Video Game Tester Jobs Can Jump Start You on Almost Any Game Development Path

September 23, 2016

Video game QA testing may be low on the game development totem pole, just above “personal projects” you’d never think about including in your resume. But used correctly, both can carry you a long way towards becoming a game programmer, story line creator, or graphics designer.It’s all about broader experience inventory and growth through progress.It would seem fairly obvious. Look at anyone in college working towards a career in a high paying field like medicine, and what do you see them doing? That’s right, working at any job in a hospital, clinic, or private practice environment (a relevant environment) which they can find. They know even a role only loosely related to the one they aspire towards in their chosen field serves as a stepping stone towards more relevant positions once the opportunity becomes available.As is the case in medicine, software development is a industry made up of many narrow roles. If you’re only focused on “qualifying for your desired role”, you may end up short changing yourself in two ways. First, by not recognizing applicable experience you’ve already obtained through non-professional work and personal hobbies. Second, by overlooking potential resume building opportunities while limiting yourself only to the ones not available to you.Let’s look at the first problem: “not recognizing applicable experience you’ve already obtained”.I don’t see this problem a lot in sales and marketing, regardless if it’s computer entertainment sales, advertisement sales, or used car sales. In fact, newer “greener” aspiring sales reps often need to learn a page from aspiring software developers about “Never put anything in your portfolio that someone wouldn’t pay you for”. Where the aspiring gaming professional falls short is recognizing what actually counts as valuable to those they present their resumes and portfolios to. They’ll often include what they consider “real job experience”, such as “Manager at Macy’s”, or “Audits and Accounting at Wells Fargo” (neither of which has anything to do with game or software development); but avoid including things like “my dorm mate and I wrote “Squares vs Circles” (an iPhone app) for fun while we were in college, it got 500,000 downloads within a month of release” (so what you are saying is, you wrote, developed, tested, and published popular and successful software on your own for fun?)It’s as if those aspiring to game development roles almost seem to have an “inferiority complex” when it comes to the kinds of experiences relevant to the gaming field. While considering any work they think of as “from a real company” with “a real paycheck attached” automatically more important. The thing is: the person looking over your resume doesn’t care about any of that. They’re not your dad who thinks you should get a “real job”, or your mom who worries about you’re “spending too much time on the internet”, they are people looking for someone with experience that has to do with games. Don’t discount experience because it was “just a personal project”. If you want to be hired in the area of game development you need to show how you have already performed successfully in game development. Whether or not you got paid, and regardless whether or not it resembles what you or your peers think of as “a real company”, “real work”, or “real professional”. What matters is that it was developing a game, and you completed the project as defined – or better. That’s what people want to hear about.

(adsbygoogle = window.adsbygoogle || []).push({});
Now take a look at the second problem: “overlooking potential resume building opportunities while limiting yourself only to the ones not available to you”.This one is a little trickier, because it requires a balancing act. You see, another important thing to remember is “Build your portfolio around a single focus”. I’m not going into detail about that here, as it mostly goes beyond the scope of this article. But, it needs to be mentioned as it’s the other end of the spectrum in so far as: on one level, you don’t want to overlook potential resume building opportunities, but at the same time, you don’t want to build a portfolio of non-relevant experience and garbage either.The best way to look at it is, if you have an opportunity to work in a position which is highly relevant to your desired role in gaming – say for example story line creator – by all means favor that work over work that’s less closely related. But when such positions are scarce or highly competitive, don’t overlook opportunity to work in any game development role – even if it falls outside the scope of the game development area you ultimately aspire towards.The reality is, jobs in game development are places where many come – but few may enter. There simply aren’t enough positions to fill in any one role for everyone who applies at the door. And even experience outside the role you aspire towards can help you as it gives you familiarity, exposure to a variety of technology, and broader experience with the roles of others you might have to later work with.The lowly and relatively low paying Video Game Tester Jobs.Compared to other gaming industry roles, video game QA tester is the lowest paying. According to The Game Developers 12th Annual Salary Survey (conducted in 2013), freelance and temporary assignment video game QA testers, with less than 3 years’ experience, earn an average of $22,000/yr., roughly equivalent to $10/hr. – assuming a 40 hour work week. This is because of the much lower amount of education needed to enter video game QA testing.However, consider those “working towards a career in a high paying field like medicine”, who I described at the beginning of this article; the ones taking “any job in a hospital, clinic, or private practice environment (a relevant environment)”. They’re doing this for a few good reasons. It helps to offset college costs, gives them a chance to gain experience and familiarization within a related work environment, and the jobs they take are often the “lower paying roles” due to lower entry-level education requirements – which equates to ease of entry. High turn-over rates as people in these positions attain the qualifications to move on to their desired careers, make these jobs readily available. And those who later move on to higher positions will have previous industry relevant experience to add to their resumes if needed. If needed being the key. If they don’t need it, or feel it would distract from experience more relevant to a particular job, they can always make less mention of it or leave it out entirely.Which bring us to the real question – why are those seeking software development careers so averse to including video game tester jobs along the way? Think back about the “inferiority complex” among “those aspiring to game development roles” which I spoke of earlier. And the corresponding “superiority complex” among those becoming “material” for higher paying, more respected roles such as graphics designer or programmer. When people think of, for example, becoming an environmental art designer, they often think of highly sophisticated technical skills, and expensive but well-worth-it college degrees – leading to well-earned and well-respected salaries. When people think of a QA tester job, they often think of someone who was lucky enough to get paid to play games.Video game quality assurance testing is seen by many as almost a kind of “red-headed-step-child”. Some treat it the same way one might treat a cheap book promising the secret to unbelievable income sold on a poorly done website alongside thin porn, payday loans, and mesothelioma related attorney services.The reality is – a video game tester job can provide the same things to the soon to be 3D character model designer that a clerical position with a small clinic provides to the soon to be medical technician, nurse, or doctor. Video game tester jobs are readily available, industry related, work with which you can offset other costs while in school or training for your desired role, gain experience and familiarity with the software development process, and which comes with relatively low entry requirements.Video game QA positions require only that you have a high aptitude for basic skills applicable to any job, such as attention to detail, ability to follow instructions, diligence, and being able to write reports. Yet they provide game industry experience, familiarity, and exposure to a wider variety of related technologies. Also, while QA testing may be “low paying” compared to other development roles, it’s actually on par with many part-time jobs that aren’t even career connected which people typically take while working towards their desired career path.

(adsbygoogle = window.adsbygoogle || []).push({});
The key is, don’t look at QA tester work as a job you “don’t take seriously”, consider it instead as a useful tool in a strategic plan. Consider those too good to be true offers you see promising “$4,000 a month playing games” for some small monthly fee. These offers are usually made by assignment aggregators. Assignment aggregators are companies in the business of offering a central location for freelance video game QA testers to find temporary video game QA assignments. Whether the promises of easy money come true or not, you could use those to get work (resume experience) handed to you even though you have not yet attained any work history or qualifications, in addition to some extra income. What you really want is for the assignments to serve as documented work history in QA Testing to support obtaining a regular entry-level position with a gaming company. You want to be able to say “I’ve completed projects in the gaming field”… as opposed to the other applicant who hasn’t.From here it depends on the options available to you, and your desired career path. If you’ve already chosen a career path in another game development role, then I’d recommend NOT moving all the way from freelance to full-time QA testing – as you want to focus your efforts on obtaining a job closer to your desired role. Until you do, you may wish to simply remain a freelance tester. Despite the lower hourly pay, this will give you the greatest flexibility and control over your time. Should you decide to become a regular part-time tester with a gaming company, the pay could actually outstrip many other non-career connected part-time jobs.If you’re still deciding when it comes to what role you want to have in game development, you may want to consider that QA testing does become more lucrative with experience – all-be-it not as quickly as in other development roles. It rises to just under $40,000/year as a full-time job with 3 years’ experience, and “maxes out” around $70,000/yr. Not as much as the $85,000/yr. you could be making as a programmer, but still fairly decent compared to other professional roles.Video game QA testing may be the lowest paid type of work in game development. However, those aspiring for such roles as game programmer, story line creator, or graphics designer would be wise to look beyond just work related to their desired role in game development.

How to Choose the Right Accounting Audit Software for Your Business

September 29, 2016

Audit professional should take his time and review available software solutions solutions on the market. Comparison, research helps, but I what I would suggest is checking testimonial section of each software provider homepages. Check if there are big companies listed among clients, what sort of services they provide. That helps to understand if solution you are willing to buy is worth it.Another great strategy is before you decide what tools to buy, or should you purchase new version of your current software, go to LinkedIn. Yes it is professional social community, where business representatives communicate with each other, share their thoughts, opinions and ideas. But, have you heard how powerful are GROUPS there. Probably not, people are not usually sharing that. In Linked in groups you can find excellent professionals that may really help you with advice or feedback regarding software you are interested in or searching for. Simply find a group for accountants, auditors or network administrators and Post a question about what tools people are using or ask to give you a feedback on any specific audit software product. I bet, in the next 3 hours, you will receive the most professional recommendations that will help you to save your budget and decide the most functional software tools.

(adsbygoogle = window.adsbygoogle || []).push({});
Another great way to get professional advice and recommendation is CPA forums. You probably heard about these communities, simply Google it and you ll find a lot of them in the first 10 search results. Usually they all have threads regarding audit software. Post a new thread asking for advice or follow the discussion. Usually these communities are small, but you will not find beginners there, it’s highly professional audience that is ready to help.

By following these simple rules you will not waste money and time on useless audit software that don’t have enough functionality to keep your work efficient.

Web Directories – Performance, Purpose, Problems – A General Guide to Web Directories

August 18, 2016

The path to building a successful web directory is far from a simple task. It requires a certain amount of devotion to take a web directory script and transform it into a heavily used directory. Web directories contain more complexities than meets the eye, and I have learned first hand that the development of a quality web directory is no walk in the park. But a good web directory is worth its weight in gold, for both webmasters & internet surfers alike. Let us enter the world of web directories.A web directory acts much like a search engine, but on a much smaller scale. Web directories are essentially a categorized index of websites that have been submitted by website owners. Directories normally have search features, allowing users to search through the entire index, just like a search engine. The main differences between a directory and a search engine is that very few directories contain the amount of links that a search engine does. Search engines also collect data from websites, which is used to categorize and rank them. Directories lack the ability to “crawl”, or exam websites as search engines due, therefore the only information a directory contains on a particular website is the information that was submitted by the website owner. Most directories use meta tags and keywords to search for websites, where as search engines use complex algorithms that take into consideration much more than meta tags (the value of meta tags in search engines has actually declined). Web directories are not the most popular internet search tools because huge search engines like Google and Yahoo are much more convenient to use and contain a vast amount of resources available to be searched. The largest and most popular web directory is the Open Directory Project (DMOZ), whose links are indexed by Google, Yahoo, and the majority of other search engines. Google and Yahoo both have their own web directories as well. Though independently owned web directories may not be so popular for internet searchers, they do have their benefits for webmasters & surfers alike.Web directories can have several purposes, it all depends on what the administration’s intended goals are. Some web directories are purely advertising hot spots, while others focus on driving targeted traffic to the directory. Some directories are free, some paid, others both. Directories can have broad topics, or specific topics. Lets start with the different types of web directories.First, we have what is commonly referred to as a “niche” directory. Niche directories have a specific topic, or niche, and the links found within the directory reflect that. Examples of a niche would be automotive directories, sports directories, shopping directories, web promotion directories, etc. Niche directories are most beneficial to internet *searchers; they have a specific topic and therefore *surfers and *searchers have a better chance of finding what they want. In a human edited niche directory, you are very unlikely to find spam sites as well.We will label the next kind of web directory as a “Free for All” directory. Free for all directories have no specific topic. They are very broad in their category selection and links are usually hidden behind several sub-categories. Free for all websites can benefit webmasters so long as the “no follow” tag is not applied (page rank increase), however it is in your best interest to avoid free for all directories for several reasons. Using a free for all directory to search for a website is more likely than not going to require you to sort through heaps of spam. A lot of free for all directories are not human edited due to the massive amount of link requests they receive, and websites are not carefully examined before being approved into the directory. The link quality of some free for all directories is extremely poor. Also, a lot of free for all directories extract data from other directories; how original. No sense in supporting the lack of creativity or devotion in such web directories. Despite a flood of low quality free for all directories, there are some very good ones available. A well organized, human edited (human edited = higher quality links) free for all directory is a great place to search for websites. It also serves webmasters with increased website exposure and if they are lucky, the directory is indexed by Google and other search engines, therefore improving its ranking on search engine result pages.

(adsbygoogle = window.adsbygoogle || []).push({});
The final type of web directories that will be examined are the poorest quality ones. Often referred to as “link farms” these directories are not human edited, due to contain high quality links, lack organization and unique features, and more often than not they become blacklisted from the major search engines. Searching these type of web directories is useless, and it’s highly recommended that you do not support such sites. Furthermore, if you are a webmaster, submitting your website to link farms will substantially decrease your popularity amongst search engines. These directories due more harm then good, and consequently give other directories a bad name.Whether you are submitting a website or searching for one, you will achieve the best results with a high quality niche directory. Webmasters, here are the common submission options for most web directories: Free submission: Submit your website to the directory for free. Simply fill out the form and wait for approval. A “no follow” tag is often placed on free submissions. Regular Submission: A small fee is usually necessary for regular submissions. Regular submissions can sometimes use the “no follow” tag. The main benefit is that submission approval times are significantly faster for regular submissions. Reciprocal Submissions: Free submissions that require a reciprocal link of the web directory to be placed onto the website you are submitting. Reciprocal submissions sometimes use “no follow’ tags, but often do not. Cost is free with reciprocal submissions. Featured Submissions: Paid submissions that grant you premium listing (websites listed in special section of category, generally above regular links), fast submission approval, and paid submissions do not place “no follow” tags on your links, meaning you gain a back link for search engine ranking benefits. Featured and regular submission fees are generally charged per year, and prices vary depending on the directory and the traffic it receives.Web directories have benefits for both webmasters and internet users. For webmasters, web directories main benefit is website exposure. Webmasters submit their websites to directories to increase their exposure. Not only can they receive traffic from people using the directory, but they can also benefit from a back link; a link to their website indexed by Google. Google ranks pages in several ways, but back links is one of the most important. A quality back link to your website increases your Google page rank. Enough quality directory back links, and your on your way to the top spot in Google search results. Bottom line: Web directories can increase your websites exposure by sending targeted traffic your way. For people using web directories as a search tool, web directories can offer you a big advantage over search engines. Search engine indexing is a big contest between website owners and therefore a lot of high quality content gets left out of the search engine result pages. Top results often go to corporations, big business, or highly devoted marketers. What about the little enthusiast and personal websites that contain valuable knowledge otherwise unavailable on the web?Well, a lot of these quality content websites can be found in web directories. If you are having trouble finding what your looking for in search engines, try searching for a niche directory and I bet you will find what your looking for. Furthermore, using web directories supports smaller businesses and helps the little guy out. Not everyone has the time or money to spend on internet marketing or website promotion, and web directories are a great way for these small websites to gain some exposure. Big search engines have monopolized the internet search market, and it makes the relationship between big search engines and website owners way to critical. Google doesn’t like you, and your sales drop 75 %. Now that does not seem right, does it? If more people frequented web directories, directory owners would gain a larger slice of the search engine market.There is a large number of web directories on the internet today that have been blacklisted by Google. It is best to avoid these directories at all costs; having your link listed there will most likely negatively affect your search engine rankings. But how do you know which directories to submit your URL to and which ones to avoid? These guidelines in rating web directories may help:1. Organization- Web Directories should be well organized and categorized.- Categories should be, neither, too broad nor too narrow. Category organization is important, but a directories search feature holds more value for finding links.- Links should be easily accessible.- Links should be posted into the correct category. If they are not, this is a sign of automated link approval, which should never be used in a directory. (Even the largest, most powerful of web directories are human edited).

(adsbygoogle = window.adsbygoogle || []).push({});
- Poor quality and spam links should not be accepted into any decent web directory.2. Advertisements- A quality directory should contain a free submission option, so it is necessary for directories to offer sponsored listings and sale advertisement space. However, the page should not be cluttered with ads. This is a sign that the directory administration is too focused on making a quick buck than enhancing the internet experience.- If the directory has a specific topic, or niche, than the advertisements should pertain to that topic. Off topic and irrelevant ads do not belong on niche directories.3. Page Rank (PR)- Rumor has it that it’s possible to fake some page rank indicators. Make sure your page rank comes from a reliable source when examining the PR of a web directory.- Page rank is important factor in website popularity. However, directories that boast high page ranks, or have their page rank in the directory name or slogan typically use the page rank factor to compensate for their downfalls. It’s like bragging…and you want a modest web directory. Find a directory that shares and uses their page rank to the benefit of directory users, not a directory that clearly lacks in features but boasts a high PR.- Directories that display website links within a category in descending order of PR are less desirable than those that display links based on popularity (unique hits). Most desirable first, not highest PR; very beneficial to new websites attempting to build initial PR.4. No Follow Tag- A web directory that uses “no follow” tags on all links is useless.- “no follow” tags are acceptable on free submissions. Reciprocal & featured submissions should not be tagged as “no follow” links. This gives value and meaning to featured (sponsored) & reciprocal links, while controlling the amount of links indexed by search engines to a reasonable number.- In a quality directory, do not fear a “no follow” on your free submission. A good directory brings in targeted traffic, and though you may be missing out on that back link, there is still a lot of potential for increasing traffic.5. Reviews, Marketing, & Promotion- Search around for reviews and recommendations on web directories. There are some really good resources when it comes to choosing quality directories.- A web directory should be marketed to both webmasters & internet surfers. If a directory only attracts webmasters, what kind of web traffic is it likely to bring? Look into how the web directory is promoted and marketed.
These 5 guidelines can help you distinguish between low quality link farms and high quality, effective web directories. I hope this information helps you in your website’s marketing and promotion campaign, in terms of website directory submission.Teal Reid, SYC Automotive Directory Administrator

Three Types Of Livestock That Can Be Raised By Beginner Farmers

August 9, 2016

When people move from the city life to live in the country side they get interested in raising livestock. The reasons may vary as to why people want to raise livestock, some people raise them as pets and some raise them because they want to make some money by selling the livestock produce.What ever reason may be, raising livestock can be done by almost anyone who is dedicated to being a livestock farmer and someone who is willing to put aside a lot of his time in managing and taking care of their livestock. In order to raise healthy livestock you have to give the animals proper care such as feeding them nutritious food plus clean water on daily bases, building them some good shelter and have them checked by a veterinarian for health issues.There are various types of livestock you may want to raise as a beginner livestock farmer. Some of them need more care than others and maybe suitable for new farmers to raise. Three types of livestock that are suitable for beginner livestock farmers are goats, cattle and sheep. Below are more details on how you can go about raising them.Raising Cattle:A lot of farmers start by raising cattle in their farm ranch. Cattle are a stress free livestock to raise when taking good care of. Their produce such as milk and meat is in high demand in the markets for its nutritious benefits. When you own cattle you will be able provide your family with fresh milk on daily bases and save lots of money in buying milk.

(adsbygoogle = window.adsbygoogle || []).push({});
When starting out in raising cattle you have to first choose the kind of breed you want to raise. There are over 800 types of breeds which are in 3 different categories known as the zebus, the hybrids and taurine cattle. Some types of breeds are good for the production of milk whilst others are suitable for meat production.When raising different types of cattle a farmer should install stalls that separate those that eat grass and hay to those that eat sophisticated feeds.Since cattle are grazing animals you have to have some large piece of land if you want to raise them. The land in which they graze on has to be well fenced so secure the livestock. For the fence you can either use electrical wiring or use a wood and steel fence. You should also prepare some equipment needed to raise cattle such as pails, water containers and feeding beds.Although cattle don’t require some sort of roofed shelter that doesn’t mean you can’t build one. A roofed shelter will also help you in storing your livestock equipment and can be used to milk your cows.Raising Goats:Goats are another type of livestock that can be raised by a beginner farmer and they are less prone to diseases than cattle. They can also be raised for the production of milk and meat which high in demand and cost more than cattle produce.When starting out raising goats you have to first make up your mind on what type of goat breed you want to raise. The type of breed depends on the end product you want to produce from your goats, you can either raise goats for the production of fiber, tasty meat and milk that is high in nutrients.Once you have made up your mind on the type of goat you want to raise you have to decide on the number of goats you are planning on raising. Knowing the number of goats you are planning on raising will help you estimate how large your land should be. One thing to note is that goats reproduce almost every year so the land should be large enough to accommodate the growth of your herd.Goats also need some shelter to rest at the end of the day. The shelter should be large enough for all your livestock to fit in properly without being over crowded. The shelter should be comfortable so that they can sleep at night and protect them from harsh weather such as too much sunlight, rain and snow. Don’t forget to fence the entire grazing land so that predators don’t attack and kill your herd.Raising Sheep:Raising sheep is very interesting and rewarding as raising cattle and goats. These type of livestock can be raised for various reasons such as producing quality wool, producing cheese from its prolific milk and the obvious tender meat. These produce can also be sold since they are in high demand.Sheep are animals that like grazing the field. If you want to raise healthy sheep then you have to have some large land of green grass for the livestock to graze on. Although feeding your sheep grain supplements plays a big part in their diet, grass fed sheep produce a higher nutritional value produce. Since sheep like grazing in a large group as a livestock farmer it can be daunting to manage them on the field so it would be wise to have a helper dog to assist you.

(adsbygoogle = window.adsbygoogle || []).push({});
An essential part of raising sheep is keeping them within their confines, this helps them in not getting lost in the wild and end of being eaten by wild animals such as bobcats, bears and wild dogs. At the same time it helps in keeping these predators out of the grazing area. Using an electrified fence can help a lot and its easy to install as well.In order to ward off natural elements that can be harmful to your livestock you have to invest some money in building good housing for your sheep. When designing the house make sure you build a chute to manage the sheep when you need to make some checkups on each and everyone of them or when vaccinating them.As you see raising livestock can be done by almost anyone even if you don’t have any past experience or were not raised in a farm ranch. Just like any other type of pet they need to be taken care for and make sure they leave in comfortable conditions.When starting out its best to first start with raising one type of livestock then move on to another type when you have gotten the experience from your first set of livestock.

Energy Explained Simply

October 7, 2016

Energy, it is fair to say, is a very vague concept. So where does one go to learn more? Does one have to take a physics course? I don’t think so, and to test my theory, I have tried to explain energy as briefly as I can, right here.Energy 101Energy is what makes the world go round. Literally. Every neuron that sparks in your brain, every electron that fires down a wire, every molecule burning in a fire, carries with it a sort of momentum that it passes on like a baton in a complex relay race. The batons are flooding in all directions all around us and across the universe – they are energy and we have learned how to harness them.The actual word “Energy” is a much abused term nowadays – because energy is used to represent such a disparate range of phenomena from heat to light to speed to weight, and because it seems to be able to change forms so readily, it is cannon fodder for pseudo-scientific and spiritual interpretation. However, you will be pleased to hear that it actually has a very clear (and consistent) nature.I like to think of energy being a bit like money – it is a sort of currency that can be traded. It takes on various forms (dollars/pounds/Swiss francs) and can be eventually cashed in to achieve something. However, just like money, once spent, it does not vanish. It simply moves on a new chapter in its life and may be reused indefinitely.To illustrate the point, let’s follow a ‘unit of energy’ through a visit to planet Earth to see what I mean. The [number] shows every time it changes currency (see the key below).The energy in our story starts off tied up in hydrogen atoms in the sun [1]. Suddenly, due to the immense pressure and heat, the nuclei of several atoms react to form a brand new helium atom, and a burst of radiation[2] is released. The radiation smashes into other nearby atoms heating them up so hot [4] that they glow, sending light [2] off into space. Several minutes pass in silence before the light bursts through the atmosphere and plunges down to the rainforest hitting a leaf. In the leaf the burst of power smashes a molecule of carbon dioxide and helps free the carbon to make food for the plant [3]. The plant may be eaten (giving food ‘Calories’), or may fall to the ground and settle and age for millions of years turning perhaps to coal. That coal may be dug up and burned to give heat [4] in a power station, boiling water to supply compressed steam [5] that may drive a turbine [6] which may be used to generate electricity [7] which we may then use in our homes to heat/light/move/cook or perhaps to recharge our mobile phone [3]. That energy will then be used to transmit microwaves when you make a call [2] which will mostly dissipate into the environment heating it (very) slightly [4]. Eventually the warmed earth radiates [2] this excess of heat off into the void where perhaps it will have another life…Energy currencies:[1] Matter is energy, according the Einstein, and the quantity relates to mass according to E=mc^2 (c is a constant equal to the speed of light).[2] Radiation (like sunlight) is a flow of energy, and energy content relates the frequency according to E=hf (h is the Planck constant).[3] Chemical energy – the most complex energy, a mixture of different tensions in nuclear and electromagnetic force fields.[4] Thermal (heat) energy- this is really just a sneaky form of kinetic energy [6 below] – small particles moving and vibrating fast are sensed by us as heat.[5] Compression (or tension) energy – while compressed air is again a sneaky form of kinetic energy[6], a compressed spring is different – it’s energy is more like chemical energy and is stored by creating tension in the force fields present in nature (gravity, electromagnetism and nuclear forces).

(adsbygoogle = window.adsbygoogle || []).push({});
[6] Kinetic energy – is energy by virtue of movement (like a speeding bullet or unstoppable train)[7] Electrical energy – this energy, like a compressed spring, is stored as stress in force fields, in this case electromagnetic force-fields.This short story is testament to an enormous quantity of learning by our species, but there are some clear exclusions to be read into the story: Energy fields (auras) or the energy lines in the body that conduct the “chi” (or life force) of Asian medical tradition
Energy lines on the Earth (aka Ley lines)
Negative or positive energy (as in positive or negative “vibes”)These energy currencies relate to theories and beliefs that science has been unable to verify and thus they have no known “exchange rate”. Asking how many light bulbs can you power with your Chi is thus a nonsensical question, whereas it would not be for any scientifically supported form of energy. And since energy flows account for all actions in the universe, not being exchangeable would be rather limiting.Where exactly is Energy kept?This may sound like s strange question, we know Energy is kept in batteries, petrol tanks and chocolate chip cookies. But the question is, where exactly is it stored in those things?Energy is stored in several ways:as movement – any mass moving has energy by virtue of the movement, which is called Kinetic Energy
as matter – Einstein figured out that matter is just a form of energy, and the exchange rate is amazing – 1g = 90,000,000,000,000,000 joules (from E=mc^2)
as tension in force fieldsThat last one sounds a bit cryptic, but actually most of the energy we use is in this form – petrol, food, batteries and even a raised hammer all store energy in what are essentially compressed (or stretched springs).What is a force field? Why on earth did I have to bring that up?All of space (even the interstellar vacuum) is permeated by force fields. The one we all know best is gravity – we know that if we lift a weight, we have to exert effort and that effort is then stored in that weight and can be recovered later by dropping it on your foot.Gravity is only one of several force fields known to science. Magnetic fields are very similar – it takes energy to pull a magnet off the fridge, and so it is actually an energy store when kept away from the fridge.The next force field is that created by electric charge (the electric field). For many years this was though to be a field all on its own but a chap called James Clerk Maxwell realised that electric fields and magnetic fields are in some senses two sides of the same coin, so physicists now talk of ‘electromagnetic’ fields. It turns out that electric energy (such as that stored in a capacitor) consists of tensions in this field, much like a raised weight is a tension in a gravity field. Perhaps surprisingly, light (as well as radio waves, microwaves and x-rays) are also energy stored in fluctuations of an energy field.Much chemical energy is also stored in electric fields – for example, most atoms consist of positively charged nuclei and negatively charged electrons, and the further apart they are kept, the more energy they hold, just liked raised weights. As an electron is allowed to get closer to the nucleus, energy is released (generally as radiation, such as light – thus hot things glow).The least well known force field is the strong ‘nuclear’ force. This is the forces that holds the subatomic particles (protons) together in the nucleus of atoms. Since the protons are all positively charged, they should want to repel each other, but something is keeping them at bay, and so physicists have inferred this force field must exist. It turns out their theory holds water, because if you can drag these protons a little bit apart, they will suddenly fly off with gusto. The strong nuclear force turns out to be bloody strong, but only works over a tiny distance. It rarely affects us as we rarely store energy with this energy field.Now we understand force fields we can look at how molecules (petrol, oxygen, chocolate) store energy. All molecules are made of atoms connected to one other via various ‘bonds’ and these bonds are like springs. Different types of molecules have different amount of tension in these bonds – it turns out coal molecules, created millions of years ago with energy from the sun, are crammed full of tense bonds that are dying to re-arrange to more relaxed configurations, which is exactly what happens when we apply oxygen and the little heat to start the reaction.The complexity of the tensions in molecules are perhaps the most amazing in nature, as it is their re-arrangements that fuel life as we know it.What exactly is Heat then?You may have noticed that I did not include heat as a form of energy store above. But surely hot things are an energy store?Yes, they are, but heat is actually just a sort of illusion. We use heat as a catch all term to describe the kinetic energy of the molecules and atoms. If you have a bottle of air, the temperature of the air is a direct consequence of the average speed of the molecules of gas jetting around bashing into one another.As you heat the air, you are actually just increasing the speed of particles. If you compress the air, you may not increase their speed, but you will have more particles in the same volume, which also ‘feels’ hotter.Solids are a little different – the atoms and molecules in solids do not have the freedom to fly around, so instead, they vibrate. It is like each molecule is constrained by elastic bands pulling in all directions. If the molecule is still, it is cold, but if it is bouncing around like a pinball, then it has kinetic energy, and feels hotter.You can see from this viewpoint, that to talk of the temperature of an atom, or of a vacuum, is meaningless, because temperature is a macroscopic property of matter. On the other hand, you could technically argue that a flying bullet is red hot because it has so much kinetic energy…Is Energy Reusable?We as a species, have learned how to tap into flows of energy to get them to do our bidding. So big question: Will we use it all up?Scientists have found that energy is pretty much indestructible – it is never “used-up”, it merely flows from one form into another. The problem is thus not that we will run out, but that we might foolishly convert it all into some unusable form.Electricity is an example of really useful energy – we have machines that convert electricity into almost anything, whereas heat is only useful if you are cold, and light is only useful if you are in the dark.Engineers also talk about the quality (or grade) of energy. An engineer would always prefer 1 litre of water 70 degrees warmer than room temperature, than 70 litres of water 1 degree warmer, even though these contain roughly the same embodied energy. You can use the hot water to boil an egg, or make tea, or you could mix it with 69 litres of room temperature water to heat it all by 1 degree. It is more flexible.Unfortunately, most of the machines we use, turn good energy (electricity, petrol, light) into bad energy (usually “low grade heat”).Why is low grade heat so bad? It turns out we have no decent machine to convert low grade heat into other forms of energy. In fact we cannot technically convert any forms of heat into energy unless we have something cold to hand which we are also willing to warm up; our machines can thus only extract energy by using hot an cold things together. A steam engine relies just as much on the environment that cools and condenses water vapour as it does on the coal its belly. Power stations rely on their cooling towers as much as their furnaces. It turns out that all our heat machines are stuck in this trap.

(adsbygoogle = window.adsbygoogle || []).push({});
So, in summary, heat itself is not useful – it is temperature differences that we know how to harness, and the bigger the better.This picture of energy lets us think differently about how we interact with energy. We have learned a few key facts:Energy is not destroyed, and cannot be totally used up – this should give us hope
Energy is harnessed to do our dirty work, but tends to end up stuck in some ‘hard to use’ formSo all we need to do to save ourselves is:Re-use the same energy over and over
by finding some way to extract energy from low grade heatAlas, this is a harder nut to crack than fission power, so I am not holding my breath. It turns out that there is another annoying universal law (the Second Law of Thermodynamics) that says that every time energy flows, it will somehow become less useful, like water running downhill. This is because energy can only flow one way: from something hot to something cold – thus once something hot and something cold meet and the temperature evens out, you have forever lost the useful energy you had.It is as if we had a mountain range and were using avalanches to drive our engines. Not only will our mountains get shorter over time but our valleys will fill up too, and soon we will live on a flat plane and our engines will be silent.The Big PictureSo the useful energy in the universe is being used up. Should we worry?Yes and no.Yes, you should worry because locally we are running out of easy sources of energy and will now have to start using sustainable ones. If we do not ramp up fast enough we will have catastrophic shortages.No, should should no worry that we will run out, because there are sustainable sources – the sun pumps out so much more than we use, it is virtually limitless.Oh, and yes again – because burning everything is messing up the chemistry of the atmosphere, which is also likely to cause catastrophe. Good news is that the solution to this is the same – most renewable energy sources do not have this unhappy side effect.Oh, and in the really long term, yes we should worry again. All the energy in the universe will eventually convert to heat, and the heat will probably spread evenly throughout the universe, and even though all the energy will still be present and accounted for, it would be impossible to use and the universe would basically stop. Pretty dismal, but this is what many physicists believe: we all exist in the eddy currents of heat flows as the universe gradually heads for a luke-warm, and dead, equilibrium.=============If you liked this article, you might like my series on efficient motoring.

Sexual Roleplaying – What it is and the Best Way to Do It

September 7, 2016

Roleplaying is simply when participants adopt and act out characters that are not themselves. Sexual roleplaying therefore is when couples act out characters with an erotic motivation as part of a sexual fantasy. It can range from being serious with costumes, accents, props, etc. to just being something that is imagined, like being stuck on a deserted island. Practically any role could be involved in sexual roleplaying as long as both people involved are interested. Pretending to be someone you are not can be fun and exciting when done correctly.Roleplaying can also be good for a marriage as it may be an opportunity for a spouse to ask for something she has always wanted done to her or done for her, but never felt comfortable asking for. For example, in a roleplay where the wife is the dominant person (boss) she might feel more open about telling her husband (employee) that she wants to have her body rubbed in a certain way that she had never asked for before. The reduction of inhibitions can be great for a marriage as inhibitions are a killer of sexual enjoyment.Some roleplaying scenarios are:* Animal-related where one is treated as a non-human animal such as a dog or pony
* Hospital fantasies involving doctors, nurses and patients
* Stranger-related one or both spouse pretend to “meet” for the first time
* School related – Headmistress and Student or Teacher and Naughty Schoolgirl
* Photographer and Model
* Stripper and Client
* Business related – Boss and Employee, Boss and SecretaryIf this is your first time thinking about roleplaying, start with something simple, like Photographer and Model and then move on to ones where the acting requirement is a little higher.Roleplaying is a lot of fun and is easy, but there are a few important requirements:1. It requires open communication
2. It requires a willingness to participate
3. It requires honesty
4. It requires not taking yourself too seriously
5. It requires establishing rulesLet’s examine these requirements in a little more depth.1. Roleplaying requires open communication – Roleplaying can involve actions that when taken too far, might be uncomfortable for one or both partners. Let’s say a couple pretends to be strangers who meet in a bar. They pretend to have different pasts and even different names. As the night continues, the husband begins to feel uncomfortable being called a different name. As soon as he realizes this, he needs to be able to communicate with his wife that he wants to end the fantasy or just be called his real name and continue, or another option he feels comfortable with. Whichever he chooses, being able to discuss that with his wife, even in the middle of the roleplaying, is vitally important.2. Roleplaying requires a willingness to participate – Perhaps a husband wants to be the boss and have his wife pretend to be his secretary with a German accent. His wife should not worry about whether that makes sense, if she knows what a secretary does all day, or if she has any idea what a German accent sounds like. She should give it her best try and of course, have fun!3. Roleplaying requires honesty – The husband finds his new doctor very attractive so he gets his wife to pretend to be a doctor and tries to make the fantasy about his new doctor. This is NOT a situation in which roleplaying should be used, nor is it the purpose of roleplaying. The husband needs to be honest with himself about his motivations for the roleplaying. He may not need to tell his wife he is attracted to his doctor, but he definitely should not start a roleplaying session with the goal of thinking about anyone other than his wife. All sexual fantasy, including roleplaying, is just a tool that helps married couples increase their sexual pleasure with each other.4. Roleplaying requires not taking yourself too seriously – In a roleplaying session, the husband might pretend to be an airline pilot while the wife pretends to be a stewardess. Since neither of them have real airline clothing, they make do with what they have. His outfit leaves him looking more like a butler than an airline pilot which could lead him to cutting short the session out of embarrassment. Instead if he is able to play around and ignore the idea that he looks silly, he will probably end up having a great time.5. Roleplaying requires establishing rules – Similar to open communication, rules are important should something need to change or stop during a roleplaying session. This might be as simple as “no” means “no” or could be something that has been pre-arranged as in a certain stopping time for a specific situation. A couple should always stay where they are both comfortable even if a fantasy heads in an unplanned direction. Also, setting and timing need to be right (as with any sexual encounter). Perhaps a roleplaying scenario was planned for today and a wife comes home from a horrible day at work. A postponing may be in order. Again, the ultimate point of roleplaying is to have fun and enjoy each other.

Cornwall’s Gardens

September 7, 2016

The ‘Garden Capital of the World’ is often how Cornwall is thought of throughout the world. Cornwall enjoys the power of the Gulf Stream with its temperate climate of warm summers, mild and wet winters which in turn allows exotic and rare plants to thrive.Where else can you find so many gardens with history dating back to the Iron Age? As long ago as the early 19th century Cornish gardeners were part of the Victorian plant hunters who collected exotic plants and seeds from all around the world.That gives us what we have today: over 60 fabulous gardens to explore with lush vegetation and sub-tropical theatres of colour brimming with exciting, rare and beautiful plants. Cornwall’s gardens are found in our magnificent Castles, Manor Houses, grand Farm Estates, Mill Houses, sheltered valleys, high up on blustery moorland and nestled in woodland and seaside gardens which meet the turquoise hues of the water’s edge.Cornwall’s gardens are so diverse as they vary in size from small and intimate to acres of rolling countryside. Some with enchanting lakes and a Victorian boathouse to water gardens with tree ferns, rhododendrons, camellias and magnolias. Others have walled gardens and manicured lawns to the newest of all two magnificent Biomes filled with magic from around the world.All around Britain you will be hard-pressed not to find a ‘Veitch’ plant or one derived from their nurseries. The Veitch family sent many collectors all over the world to bring back seeds and plants. These included two Cornish brothers, William and Thomas Lobb. William Lobb died in San Francisco in 1864 but his brother Thomas lived in Devoran until his death in 1894.In the East of Cornwall Mount Edgcumbe have The Earl’s Garden with ancient and rare trees including a 400-year-old lime. The Formal Gardens are found in the lower park and were created over 200 years ago in English, French and Italian styles. Cothele tells the story of the Tamar Valley and Antony was recently used as a backdrop for the film Alice in Wonderland. Also in the East is Ince Castle which overlooks the River Lynher. The garden enjoys woodlands filled with rhododendrons, camellias and magnolias, vibrant shrubs and formal gardens. Pentillie Castle’s gardens are only open on specific days and their orchard was replanted with old Tamar Valley varieties of apple and cherry.The South is awash with fabulous gardens which proves how sheltered this coast is in Cornwall and many are overflowing with collections of Cornish rhododendrons, camellias and magnolias. We can start with Hidden Valley Gardens, Near Par. These gardens won the Cornwall Tourism Silver award 2010 for small visitor attraction. Tregrehan is a large woodland garden and is home to the Carlyon family since 1565. The Pinetum Park and Pine Lodge Gardens, Near St. Austell is a 30-acre paradise with over 6000 labelled plants. Ray and Shirley Clemo travelled the world collecting seeds and plants for this garden and a pair of black swans have made it their home.

(adsbygoogle = window.adsbygoogle || []).push({});
The Lost Gardens of Heligan at Pentewan have been voted Britain’s finest garden and has scooped the title in the Countryfile Magazine Awards 2011. Celebrating 21years since Heligan’s Lost Gardens were discovered, this beauty provides 200 acres to explore. Discover the Northern Garden, the Jungle, the Wider Estate and the Horsemoor Hide and Wildlife Project.Next on our list would be Caerhays Castle Gardens which is situated in a valley above Porthluney Cove. A horticultural treasure covering 100 acres of woodland gardens and holder of the National Magnolia Collection. Lamorran at St. Mawes is a Mediterranean-style garden with sea views over Falmouth Bay. History says that it is the most Northerly Palm Garden in the world. From Lamorran you can see the lighthouse at St. Anthony’s Head. St. Just in Roseland has a 13th century church and is set in a sheltered sub-tropical riverside garden filled with magnolias, azaleas, bamboos and giant gunnera. Trelissick Garden at Feock was planted 200 years ago and has views down the Falmouth estuary. It has year-round plant colour, an orchard, woodland walks and an art and crafts gallery. In the autumn 300 varieties of apples will be on display in the Georgian stables. Enys Gardens at Penryn is one of Cornwall’s oldest gardens dating back to 1709. Penjerrick at Budock Water is unspoilt with historic and botanic interest; relax among tree ferns and hidden paths.Moving on down the coast to Mawnan Smith is Trebah and Carwinion, these are gardens with great historic interest. Trebah is on the North bank of the Helford River and in this garden you can wander among giant tree ferns and palms. Carwinion has a renowned collection of bamboo and has 14 acres of tranquil gardens. Glendurgan lies in a sub-tropical valley running down to the Helford River. Have fun in the 180 year-old cherry laurel maze and wander through the garden and down to the hamlet of Durgan. Potager is a new organic garden and is close to Constantine, five miles from Falmouth.Down the coast further to Cornwall’s Lizard Peninsula, Bonython Estate Gardens has an 18th century Walled Garden, a potager garden, an orchard of Cornish variety apple trees and woodlands. Bosahan at Manaccan is again close to the Helford River enjoying the Cornish microclimate and described as “the most Cornish of all Cornish gardens” in The Gardener magazine in 1909! Trevarno Gardens are the ‘Jewel in the Crown’ of their estate with a magnificent 70 acres. Several interesting features include a Serptentine Yew Tunnel and the production of organic skincare products and soaps. Carleen Subtropical Gardens are open by appointment only and are home to collections from South America, Mexico, Central and South Asia, Australia, New Zealand, Southern USA and the Mediterranean. The Hardy Exotics Garden Nursery at Whitecross, Near Penzance can create “Barbados in Birmingham” – “Mauritius in Manchester” and “Hawaii in Hertford”.Now we come to the beautiful St. Michaels Mount, walk across the causeway at low tide or travel by boat at other times. These gardens are steep but thrive in the shelter of the granite cliffs and you will find exotics from Mexico, Canary Islands and South Africa. Tremenheere Sculpture Gardens is a wonderful valley setting with St. Michaels Mount in the background. The National Trust owns Trengwainton and this historic garden is home to banana plants and enormous echiums. Finally in this part of Cornwall is Penberth which has 5 acres and is a natural valley garden incorporating sea views.Now we move on to North Cornwall which is a more rugged coast fronting the Atlantic. Our first port of call is the Japanese Garden and Bonsai Nursery in the beautiful Lanherne Valley at St. Mawgan. Just 1.5 acres but includes Water Gardens, Stroll Garden and a Zen Garden inspired by the East. Moving on up the Coast to Padstow we find Prideaux Place that has 40 acres of landscaped grounds and a deer park overlooking the Padstow estuary and the River Camel. Last but not least on this coast is Longcross Victorian Garden at Trelights, Port Isaac. This is 4 acres and gives a fine example of coastal gardening and hedging with views towards Port Isaac and Port Quin.Cornwall has some more fine gardens that are a bit more inland than the others we have mentioned before but when you are in Cornwall you are never more than sixteen miles away from the coast at any time.The 4 acres at Ken-Caro, Nr. Liskeard is another garden with a woodland walk, magnolias and rhododendrons, small but beautiful and set high above Bicton Manor Woods. Another one in the same area is Moyclare established in 1927 in 1 acre and arranged around the house. The broom “Moyclare Pink” and the astrantia “Moira Reid” originated in this garden. Pencarrow is a garden of 50 acres and this is where the Monkey Puzzle tree got its name. In this garden you can even walk on the grass! If you like one of the plants you will probably be able to buy a cutting from it. At Pinsla Garden, Cardinham there is something for everyone, an idyllic haven, and a hideaway full of secret paths with hazel arch and fantasy garden created by garden artists.Moving on once again to the National Trust owned Lanhydrock, a garden for walkers and a historical garden that has a woodland of 1000 acres. Boconnoc at Lostwithiel bas a beautiful spring garden and has camellias and azaleas from the 1850 original planting. These gardens are only open for the Spring Flower Show and Sunday afternoons during May. Trewithin close to Grampound means ‘house of the trees’ and has 30 acres of woodland gardens and more than 200 acres of surrounding parkland. The horticulturalist George Johnstone, who inherited the house in 1904, cultivated many of the seeds that came from abroad thus ensuring the reputation that Trewithin has today. Trewithin is an unforgettable garden gem.Next is the Eden Project close to St. Austell which is the newest of all our Cornish gardens. Created from a disused china clay pit in the year 2000 and the site opened on 17th March 2001. Two Biomes, one Tropical and the other Mediterranean are both constructed from a tubular steel space-frame clad in thermoplastic ETFE. At Eden you can travel around the world in a day!

At Bosvigo on the outskirts of Truro an awkward wing of the house was demolished and using stone from the house the walled garden was created. This left a 100-year-old Victorian Conservatory standing. All the plants that are for sale in this nursery are growing in the Gardens. Burncoose at Gwennap is a 30 acre woodland garden and has achieved gold medal displays at Chelsea and Hampton Court flower shows. The Nursery stocks a wide range of shrubs and herbaceous plants. Back up the coast we find Trerice, three miles from Newquay, which is a 6 acre garden but there is still space to find seclusion at any time of the year. The National Trust has owned this garden since 1953.Finally, we cross the water and arrive on the beautiful Isles of Scilly and then head for the Abbey Gardens on Tresco. This amazing sub-tropical garden is home to species of plants and trees from 80 countries ranging from Brazil to New Zealand and Burma to South Africa. The building of tall windbreaks ensures any inclement weather is forced up and over the walled enclosure. The terraces at the top are hotter and drier than the ones below which give more humidity. In 1990 hurricane force winds created dreadful damage to the shelter belts and the loss of many plants but the shelter belts and garden are now restored and looking ‘better than ever’. This is one that you should not miss.Many Cornish gardens belong to the National Gardens Scheme who publishes The Yellow Book each year which is a guide or ‘bible’ to garden visiting. Most of these gardens are privately owned and only open on specific days.Lots of our gardens have tremendous interest in the Autumn such as Ellis Gardens at Polyphant, Wave Cottage at Lerryn, Half Acre at Boscastle, Primrose Farm at Skinners Bottom and Kennall House at Ponsanooth. The Homestead close to Helston is 7.5 acres and has a Wildflower Wood with over 1000 trees and a further 800 trees for a shelter and wildlife habitat.There are of course many more gardens in Cornwall, many of them small but beautiful and a lot of our gardens are Dog Friendly. So don’t leave part of the family at home, bring them along as well. It would be wise to check first with the garden you are intending to visit just to make sure that it is ‘dog friendly’. Some of our Cornish gardens are more accessible than others so again if part of your group is less agile check with the garden to make sure you will enjoy your visit.For more information on our Cornish Gardens most of them have their own website which will give you opening days and times, how to get there, what facilities are available and ticket costs.

How to Choose the Best Jewelry and Watches?

August 26, 2016

Are you interested in purchasing a new watch? This is an important decision as you will need to find an accessory that will really add value to yourself. There are some criteria that you will have to respect when purchasing a watch or a jewel. The aim of this article is to provide you some more information on this topic to help you take the best decision.First of all you should consider your dress. Whenever you are purchasing jewelry or watches you should always make sure that it is suited to your clothes. This is because not all watches or jewels will match your dress and you can end up with an unpleasant surprise. This is why it is advised that you wear something close to the dress that you will be wearing at the party before purchasing your accessories.

(adsbygoogle = window.adsbygoogle || []).push({});
It will also be important that you take into account your personality. There are some people that may look great with a particular accessory but another may look weird. Do not make the mistake of buying jewelry or watches just because they are merely fashionable. Instead it is important that you buy jewels that match your personality. Take adequate time to try the watches or the jewelry. It might also be interesting for you to bring a trusted friend along in order to get some feedback.You should also take your budget into account. We all want to have the most exciting jewelry or watches but we should be realistic. If it is beyond our budget then we should forget it. There is no point in breaking the bank in order to buy an accessory that you will be wearing only once in a while. You will end up being more profitable by investing the money in some other items.

(adsbygoogle = window.adsbygoogle || []).push({});
You should exercise caution when purchasing jewelry and watches. It is easy to succumb to impulse buying and purchase something that does not match your personality and only for it to finish at the back of a cupboard. There are even people that buy such accessories in order to feel accepted by their peers. It is important that you avoid such mistake at all cost.

Traveling With Electronic and Electrical Appliances

September 21, 2016

Whether they’re traveling for business or for leisure, every international guest that stays at a hotel or a bed-and-breakfast inn brings along an electronic or electrical appliance to use during the trip. Almost always there’s a mobile phone or smartphone, a tablet, or a laptop in their luggage. Most laptops or phones have dual-voltage capability and only need corresponding travel adapter plugs that fit into the sockets of the country they’re visiting. The following information should help travelers choose the right adaptor plugs to bring along in their trip.About Electronic and Electrical AppliancesThough both categories of appliances run on electricity, electronic appliances often need transformers with specific outputs, such as a power converter that accepts an input of 110 to 120 volts and only outputs 220 volts. Appliances with electronic circuits or chips, such as clock radios, battery chargers, and computers, should be used for short periods of time, preferably less than three hours. Plugging in these electronic appliances for long might cause overheating and lead to fires.

(adsbygoogle = window.adsbygoogle || []).push({});
Meanwhile, electrical appliances that provide simple heating functions, such as a flat-iron, water heater, or hair dryer, must be used with a converter or transformer with the corresponding wattage for no more than an hour at a time. The sockets available in bathrooms of hotels and inns in European countries maybe labeled as 220 to 240 volts AC, but these were designed for use with low-wattage appliances such as shavers and electric toothbrushes that need around five to ten watts. They’re not fit for use with a hair dryer, a travel iron, or a phone charger for long hours.Identifying Dual-Voltage Appliances and WattageIf you want to know whether your appliance is dual-voltage, simply check its package for a 120/240 label or look at its plug for any embossed electrical information. These appliances won’t need a converter or power transformer. However, you may still need to find their wattage. When only the voltage and amperage are given, the formula to find the wattage of an appliance simply multiplies the volts with the amps. For instance, 120V multiplied by 0.5A equals 60W, which means an appliance that needs 120 volts at 0.5 amps should run at 60 watts of electricity.Travel Adapter Plugs and Power Output StandardsMost homes and businesses in the United States, Canada and Mexico use 100 to 120 volts of power with around 60 Gigahertz of alternating currents. The rest of the world outputs 200 to 250 volts at around 50 Gigahertz of alternating currents per cycle. Most travel adapter plugs used in North and South America have two parallel flat prongs for the non-earthed types while the earthed type has a grounding pin below.

(adsbygoogle = window.adsbygoogle || []).push({});
In some countries in Europe, the plugs must have two rounded pins parallel to each other. Grounded types have a third pin or flat prong below the pair. Great Britain, in particular, uses a double-rounded pin plug with a flat prong for grounding. In France and Belgium, their plugs have grounding clips instead along with the two-pronged structure. In Australia, the prongs were arranged in a V-shape set at an angle to each other.

Use of Drones in Aerospace/Defense

October 9, 2016

The development of unmanned aerial systems, or drones was initially for military purposes. As these aerial systems did not require an onboard pilot, they were seen as a useful weapon on the battlefield. Not only does a drone decrease the mortality rate of the soldiers, it also provides the military a chance to spy on the enemy in a discrete manner.Drones have become an important component of national defense for the following reasons.· A drone is an unmanned vehicle, that is, it does not require any one to be on it to be controlled. This is possible because it can be controlled using a remote control. Though it is mandatory that it is still controlled by a trained pilot, it does not require the pilot to go with it.

(adsbygoogle = window.adsbygoogle || []).push({});
· The US military has been using drones to search for terrorists in Afghanistan and have proved how useful they are for conducting covert military operations.· Drones can be used for various purposes such as searching for hidden terrorists, gunning the terrorists down in their own areas and searching for the hidden landmines using hyperspectral imaging sensors.· Keeping an eye on the air space of the country.· Keeping a check on the borders of the country without threatening the lives of the most precious soldiers.The use of the US Army’s Global Hawk in the combat field of Afghanistan has already made news. This has triggered a race between countries to own and develop this technology as soon as possible. Countries like UK and China and India are already way ahead in the research and development of drones for their respective defense forces.The use of drones even by the army is not only for combat and espionage purposes. This technology is largely being developed for the times when a crisis hits the nation. The military is trying to use drones in areas that have suffered fire or earthquake where the military and air force is called in to rescue people. This is the humanitarian aspect of the use of drones. Drones are sent in difficult to reach places to search for survivors. When the images from a drone shows the presence of any survivor, special teams are sent in to carry out rescue operation. This has saved many lives and is sure to save a number of lives in future too.

(adsbygoogle = window.adsbygoogle || []).push({});
The countries that are trying to be the controlling factors in the world need to have this technology soon. UK has started by bringing together all of its top engineers to develop homemade UAVs and there were news about the flight of their first UAV named Taranis.The use of UAVs cannot replace the fighter jets or the satellites, however, they can be used for surveillance missions that can’t be performed by fighter jets as they are too big and therefore can be spotted quite easily by radar. Drones are definitely one of the “must haves” for any good army in the future.
