Proper Training Is Essential If You Want To Become An Electrician

Technology plays an important role in our lives today. It has penetrated into almost all the departments that we know. Education is no exception to this rule. Gone are the days when educational institutions had to burn the midnight oil to prepare exam papers for their students. Today, these question papers can be prepared in a jiffy, thanks to the technological advancements. Currently, there are lots of software packages that aim to make your life easy by creating innovative, responsive and interactive exam papers for all levels. Let us now look at some of the features and benefits of these packages:

Win-win situation for the teacher and the taught

Online examination software's main objective is to create a mutually beneficial scenario for the educational institutions and the students. Self-explanatory and straightforward questions with relevant options make the lives of students easier, as they don't have to waste time in reading between the lines like they usually do in the traditional format of exams. For the institution, this software not only helps in preparing the questions but also helps immensely in correcting, tracking and grading as well. You can easily download these packages from the internet and use it on your mobiles, laptops, tablets and desktops as they are compatible with all platforms. There are quite a few electrician qualifications you need to do this type of work safely and effectively. Getting involved with a top-notch program is a very important step in this process. It makes sense to have a solid framework in place. Then you can continue to build on it for a lifetime, over the span of your career.

There are many skills and areas of knowledge you need to do well with this type of work. Troubleshooting is a big part of the work. Knowing what needs to be fixed and how to fix it begins with outstanding electrician qualifications in place. A great program helps you learn through classroom setting work and hands on exercises that help you to problem solve.

New Career

Perhaps you have always been interested in the world of electricity. For others, this is going to be a career change. Regardless, you have to be committed to learning and to be safe. Paying attention to details matters. There are rules you must follow to make sure the work environment and everyone in it remains safe.

There are specific areas of this type of work you may wish to train in. Those specific areas need more electrician qualifications because they are more complex and precise. Yet they can give you a challenging and rewarding career. They often pay more too which can be an added bonus.

Safety

Any program you take part in offering electrician qualifications should be focused on safety. No matter how large or small the project is, that is at the core of it. There are rules for locking out machines and for testing. Following these procedures every single time reduces the risk of injury or death to anyone in the work area.

You can't be in a hurry and you can't cut corners when it comes to safety. Being well-trained on what to look for relating to potential risks is very important. Wearing safety gear to any work site is also going to cut the chances of something harmful taking place. While this can be a wonderful career, you have to know the risks too.

Testing

The training you get is going to be preparing you for the testing you will eventually take. You will need to pass those tests to verify your electrician qualifications. If you have planned, ready, learned, and asked questions you should be well ready for the testing and pass without any concerns.

Establishing Relationships

Throughout your learning and training, you will have an opportunity to meet a variety of people. Many of them are trying to get the same qualifications are you are. Some of them are already experts and they take pride in sharing what they know. Others are part of support services and they will do what they can to help you connect with the right program.

Some of these relationships will become very strong bonds. While you share a common interest in the field of being an electrician, it can branch out to many other areas of your life. This can be a wonderful bonus along the way. Imagine being shipwrecked on a remote, hot desert island many miles from the nearest civilisation. You spend each day foraging for food and fresh water whilst keeping out of the blistering sun with the shade of dried papyrus leaves and avoiding the acid bites of the always present termites.

One day you spot a bottle bobbing in the sea and swim out to recover it with view to later using it as a message carrier in the traditional @castaway@ manner. You have plenty of dried papyrus leaves to use as a writing material but you need the means to write the detail of your message. The chalk and charcoal that you have at your disposal do not fit the bill due to their size and inability to persist within a watery environment. A fine tipped, more precise writing instrument that will make permanent marks is required, something akin to the humble ballpoint pen that we have known and have loved for many decades.

With such an item of "advanced" technology, it would be possible to write many lines of text in a small space and know that the writing would have some chance of surviving many months at sea. Additionally, such a pen made of its hard shell would resist the hungry advances of the local termite population.

In the modern world over 150 billion disposable pens are produced every year, and yet on your desert island there is not one. The only solution is to make such a device, a device made of a mere half a dozen very simple components.

It cannot be that difficult, can it? The familiar ballpoint pen is such a simple device. A small waterproof tube to act as a reservoir for ink, a tiny rolling metal ball to deliver the ink onto the writing surface and a small metal housing to connect the reservoir, ink and ballpoint. All of this is housed in a small neat and tidy hard-wearing outer a case of plastic. To finish the whole thing, a small plastic cap is used to plug the tube. Simple!

So, consider how would you go about making one on your desert island?

First, the ballpoint: a tiny hard-wearing metal bead formed into a perfect sphere to allow smooth rotation and delivery of ink from a reservoir onto the writing surface. This tiny sub millimetre ball needs to be highly polished and may even benefit from tiny pits to help transfer the ink. The metal of choice for this component is normally tungsten carbide, and fortunately tungsten is available on your island. It simply needs to be extracted from the ground, pulverized into a very fine powder, heated, combined with readily available graphite and heated again to temperature of a mere 2000°C. For this particular task all that is needed is for you to create an extremely high temperature oven!

Once the tungsten carbide is formed, a way needs to be found to form it into a pellet less than a millimetre across and then shape and polish it into a perfect sphere. Once this has been achieved, the tiny sphere must be carefully put to one side in the hope that it doesn't get lost.

Next, the housing to hold the tiny ball. This can be made out of a basic metal alloy such as brass. Fortunately quantities of the common elements of copper and zinc are also available on our island paradise and using the oven, a reduced temperature of a mere 1100 °C is used to smelt carefully controlled quantities of both these metals to produce a small brass ingot. This is then formed into a small conical shape to act as the point for the pen, and then using a half millimetre drill that we fabricated out of high carbon steel in last months workshop(!), we form a fine hole down which the ink can travel. Very carefully, a wider pit in the brass pen point is formed to place the sub-millimetre tungsten carbide ball into and very carefully a narrow brass edge is folded over to help hold the micro ball in its pit.

Now for the ink. This really cannot be too difficult to do, it is only ink after all!

First it is necessary to find a carrier liquid in which to suspend some form of pigment. The pigment will be made by grinding highly coloured local materials into an extremely fine powder, so fine that it will not clog the very fine ball in the ballpoint and prevent it rotating. In order that the ink will flow smoothly and without drying out, it needs to be made out of some form of reasonably clear oil. Fortunately the island is populated with a plentiful crop of castor oil plants, perfect for the extraction of vegetable oil as long as extreme care is taken not to be poisoned by the highly toxic Ricin contained within the castor oil plant seeds.

Next a reservoir for this ink made from some form of durable, ink proof, non-degradable substance such as plastic. Being a clever castaway you are aware of the fact that bio derived materials such as egg and blood proteins have been used for centuries to create various forms of plastic materials, but that these are not very hard-wearing. Ideally some form of thermosetting plastic would be used that can be easily shaped with a little heat and will remain hard after it has cooled.

Given a chemistry set containing various highly toxic substances such as acetone, sodium cyanide and methyl alcohol, it may be possible to react these in a precise and controlled manner to form a suitable plastic. Unfortunately such a set was not washed up on the island, and in this case the easiest route is to find a straight and suitably sized dried out and hollow plant stem (eg a strong grass or small bamboo), and coat it with some plant resin to prevent the ink drying out too fast.

So, after many months of hard toil, this simplest of writing implement can be assembled, carefully filled with ink and a S.O.S. message finally prepared on a roll of finest Papyrus leaf. This is placed in the bottle and the neck sealed with some leftover plant resin. With one smooth action the bottle can be cast into the sea to begin its long journey.

Whilst waiting for a response and rescue, this "ordinary" lightweight, durable device could then be used to keep a daily diary, to doodle, to label, to calculate, to improve drawing skills, and can be taken anywhere on this hot and humid desert island as and when needed. Naturally, after months of effort this valuable item would be treated very, very carefully Academics call businesses unethical and dishonest. This seems problematic to me. First, it is amazing how often those who have a certain character flaw call out others when they notice others have that similar flaw. Second, academia has a tremendous amount of ethics rules, why? I mean if academia is so noble and ethical to call out businesses, then they certainly must be beyond reproach. Unfortunately, they aren't and they know it, thus, trying to control themselves through rules. Sometimes this works for them, sometimes it doesn't, but they believe businesses must be controlled by rules that they in their infinite wisdom believe will keep everyone honest.

Remember this coming from a group that isn't honest and thus, has to enforce their own to be good (being sarcastic of course). A group that gets its money by charging outrageous tuition fees and economically enslaving their students with college load debt, while brain-washing them into a socialist mindset. A group that has never had to make a profit or run a business - yet, tells us they are wiser than those of us in the free-market and therefore, should make the rules that we run by. This is flawed logic - why you ask?

It's simple; in the free-market we are kept ethical by the customer, client, and consumer - if we fail to deliver, then we'll be out of business and lose market-share as soon as those negative YELP comments start coming back - why do we need academic inspired increased regulations for that? We don't, but isn't that just like the arrogance of academia to think that they should be the Philosopher King's over our domain.

Okay so why the hard-hitting commentary from our resident genius you ask? Well, because soon the academic bubble will pop, just like any sector that grows too fast - the longer this goes on the bigger the bubble and the harder the fall. But who will they blame when the bubble bursts - sure it could perhaps go another 5-10 years, anything is possible, but the end is now known, tuition costs cannot keep rising and we only need to have an economic downturn and it will erase the ability to continue this hyper-growth. Today we see politicians calling for debt-free tuition (FREE) but of course we all know that is all it will be worth if they are able to make it so.

For a group of academics and politicians running around calling everything they don't like "unsustainable" it is ironic that they are creating some of the most unsustainable sectors of our entire economy.

Now then, everyone knows ethics are important in science, and yet, the claim of integrity is questionable - because if everyone in the process was so ethical by nature as arrogant academics often purport - then we wouldn't need all the checks and balances in the grants review process. What we have now is runaway bureaucracy and typical government administering $100s of Billions per year propping up the academic bubble even further - to what avail I ask? Pure science - you ponder? Doubtful, we don't need that much regulation and rule-making or bureaucracy for pure science - we need less of the former and more of the latter in my observation.
We can simply explain flowers as blossoms or blooms. Science teaches us that the flower is the reproductive structure of a plant and facilitates fertilization. The ovary of the flower develops into the fruit that we consume; most fruits contain seeds from which further plants can sprout. Flowers offer different kinds of fertilization or fusion -

• Selfing - which is the fusion of egg and sperm from the same flower

• Outcrossing - fusion of egg and sperm from different varieties in a given population

Flowers have evolved just like other life on Earth; some produce diasporas without fertilization, some make themselves attractive to insects and animals so that pollen transfer takes place.

While these facts may seem very simple for us to absorb, in reality flowers are a very complex mechanism of nature with different properties and aspects that have enabled them to survive through many millennia through coping mechanisms.

What we know about flowers generally is that they are an object of beauty and admiration and are used to beautify and enhance spaces and environments as objects that are not only synonymous with religion, ritual and romance but also as sources of food and medicine.

A University of Texas study shows that bees not only pick up food i.e. nectar and pollen from flowers but also transmit bacteria to the flowers through their 'micro biomes' which is the term used to indicate the community of bacteria in the bee's gut. One of the most common bacteria is Lactobacillus Micheneri, largely associated with fermented foods. Lactobacillus is a common bacterium, also called 'good bacteria' and plays an important role in ensuring good health. This type of bacteria is found to accumulate more on flowers that are pollinated by wild bees that are mostly solitary and carry pollen on their undersides.

Such research throws a great deal of light for future bee research and the role of flowers. It helps us to learn that flowers are not just sources of food but also act in transmitting good bacteria that help protect pollinator populations.

While not all flowers are beautiful and fragrant, some flowers have evolved in the most strangest of manners to ensure survival. The 'corpse flower', so named because of its putrefying smell of decaying animal flesh and urine grows on a plant that is quite small. Its original presence was in the dense jungles around the world. To attract bugs and insects the flower made itself become bigger and bigger and smellier to attract pollinators and reproduce more efficiently. Some specimens flower only once a year while some others take longer. Probably the best introduction India receives globally is through its Indian curry. What actually is Indian curry and for how long we have been enjoying it are 2 topics that are no less than mysteries, until recently, when archaeological evidences have shed light upon curry's date of origin. Dictionary describes curry not as a single dish but the term is used for a mind-blowing number of spicy meat and vegetable stews from as far-flung places as the Caribbean Islands, the South-Pacific and of course, the Indian subcontinent. What constitutes a curry is a major debate and it hardly seems to get a fitting answer very soon.

Colonial History of Curry

The term curry probably has its origin in Tamil term 'kari' used to describe a spicy sauce. Bewildered by the region's large variety of lip-smacking dishes, the 17th century British East-India traders mixed them all under a single term called curry. As defined by the British, one may call curry as a blend of ginger, turmeric, onion, garlic, coriander, cumin and chilli cooked with vegetables, shellfish or meats.

We cannot say that the present form of curry is exclusively an Indian creation. Culinary traditions of Middle-East and South-East Asia have considerable amounts of influence to give it its present form. Trading relation with South-East Asia has introduced cloves into the Indian cuisines whereas large consumption of meat among the public was reported after Muslim invasions from 1000 AD onward.

Europeans came in touch with the taste of Indian curry after the Portuguese set up their trading posts on western coast of India. They introduced chillies and spices from the New World inside the European kitchens. However, the basic form of curry predates the presence of Europeans in India by more than 4000 years as is revealed by recent archaeological excavations at a site of Indus Valley Civilisation.

Prehistoric Origin of Curry

Established duration of Indus Valley Civilisation spans from 3300 to 1300 BCE. One may say that this was the golden age of Bronze Age India. Until recently, historians have few evidences to know about the food habits of these people when significant development came up from the study of starch grains at the North-Indian site of Farmana. The granules were extracted out of pot vessels, dental remains of human burials and stone tools.

Hows to fix your eyes to your goal for fast achivement

Silicon Carbide is also known as the carborundum. It is a compound that is made with the elements like carbon and silicon. The chemical formula of this compound is SIC. It occurs in the natural state in the raw mineral form known as the moissanite. From the year 1893, this compound is being mass produced to be used as the abrasive. A small amount of grains of SIC is bonded together by the process of sintering to form a hard type of ceramics. They are widely used in various applications including car clutches, car brakes, bulletproof vests and ceramic plates. In the electronic field, this compound is largely used as the light emitting diodes and detectors.

Apart from the above usage, this compound is also used in the semiconductor devices that work in HV areas. Large crystals of SIC is made with the help of the Lely method. They are cut in a gem like structures.

Background-

Carbide is a hard covalent compound that is largely produced by the process of carbothermal reduction of silica. Depending on the exact reaction situations, the resultant SIC that IS formed is either fine powder or occurs in the ground mass state.

Key properties-

There are various properties of this material. It is a refractory material that is having high melting point. It is having high thermal conductivity and low thermal expansion. Additionally to it, SIC is hard in nature, corrosion resistance and highly stiff. Carbide has interesting properties due to the various semiconductor features.

Commercial grading of SILICON Carbide-

The commercial Sic products that are used for the engineering applications are available in three forms- one is the sintered silicon carbide, nitride bonded silicon carbide and the reaction bonded silicon carbide. There are various other types of Sic forms available like the clay-bonded SILICON carbide and the SIAION bonded SILICON carbide. The first form is used in various refractory applications depending on the manufacturing needs.

There are various benefits of using the SIC in the electric voltage purposes. This compound is having high voltage acceptance than the silicon. SIC switches are placed in series and are required in various HV requirements. It reduces the system complexity, cost-effective and reliable too. Sic operates in the region of higher temperature like 400 degree that is more than silicon. Thus, it helps in reducing the cooling costs and complexities in the HV areas. These are some of the benefits of using SIC.The ongoing battle of words between Piers Morgan and Virender Sehwag seems to be reaching new heights, at least as far as Piers Morgan is concerned. The man may be quick to admonish anyone who doesn't 'dot their I's or cross their T's but his insistence on grammatical sentencing and spelling is not going down well with a lot of people. The poor 'bard' must be literally shaking in his grave!

English is a funny language, we have heard many say. And indeed it is through its nuances of sounds and spellings that can throw even the most seasoned off-guard. But without doubt English is one of the most widely spoken languages and easily the most popular for communication at international levels.

The new British Prime Minister, Theresa May recently announced a huge reform to the UK education policy by calling for a new generation of selective schools. She has vowed to bring in legislation to overturn the ban on new grammar schools, a policy which has been in effect since 1998. Grammar schools have had a dubious distinction of taking up for the higher echelons of society.

But first, let's understand what a 'Grammar School' is.

A grammar school is that which selects its students through an examination called the '11-plus', which means that children of that age take the exam. By virtue of this, it attains a special status. Under the system, a child who passes the exam is eligible to attend the local grammar school while a child who fails goes to the 'secondary modern school'. In certain boroughs and counties in the UK there are no grammar schools which are non-selective with no special status although they bear the name of a grammar school.

The modern school was made effective through the Education Act of 1944 although the concept of these schools goes way back to the 16th century. Secondary Education was reorganized into two types namely grammar school education and secondary schools. Through the former it was assumed that pupils would move on to higher studies by focusing on academics while the latter was meant for those children who would take up a trade or technical jobs. It basically segregated those that would go on to university studies and celebrated professions and those who seemed more suitable for lesser jobs. Many children in India (belonging to low-income families) find themselves thrown into the real-world battles quite early in life. In a country where Right to Education is a law, as many as 126,66,377 children work in various sectors only to earn their meal for the day. Yet, a change has been brewing steadily where children today are opting education over work.

Every Child Must be Educated

Earlier, many families considered a child to be an additional resource to fetch income to feed the family and to feed the children. This has considerably changed over the years. Thanks to the initiatives and schemes by the Government of India, many children are now encouraged to attend school. Additionally, when the children started to benefit from mid-day meal schemes in schools, they started bringing along their siblings which solved the problem of most parents.

The Changes over the Years

The 1998 National Census of India estimated the total number of children workers, aged 4-15, to be at 12.6 million, out of a total child population of 253 million in 5-14 age group. The 2011 National Census of India found the total number of working children, aged 5-14, to be at 4.35 million, and the total child population to be 259.64 million in that age group. So yes, the numbers have declined but the problem of putting children to school remains to be solved.

A National Policy on Child Labour was formulated in 1987 and ever since, the government has tried to ensure children attend school. One of the more remarkable steps of the government has been the enactment of 'The Right of Children to Free and Compulsory Education Act' or Right to Education Act also known as RTE. It was enacted on August 4 2009, which describes the modalities of the importance of free and compulsory education for children between 6 and 14 in India under Article 21A of the Indian Constitution. In addition, the government set off to accelerate the various policies about children's education in its existing system.

One such step was the launching of Mid-Day Meal Scheme in 2004. This scheme has seen several reforms over the years with a view to include all of government schools in the system. The primary objective of Mid-Day Meal Programme is to feed one wholesome meal to children in order to encourage them to come to school. The government has tied up with non-governmental organisations in order to implement MDMS efficiently in schools to reach out to as many children as possible.

Benefits of Mid-Day Meal Programme

Children are now encouraged to attend school and this has so far proved to be a win-win for parents belonging to economically weaker sections. The parents are now realising that they can feed the children by relying on school lunch programmes. The Mid Day Meal Scheme has benefitted the children in more ways than one. Properly-fed children feel more motivated to work hard on their academics, experience an overall physical and mental growth and understand the importance of having ambitions for future.

The impact on the lives of the children has been tremendous ever since the organisations has implemented its Mid-Day Meal Programme. There are stories of hope where children have been benefitted for real in the mission of Food for Education. You can be part of this amazing cause of encouraging children to attend school. Sponsor a child today! That is the inscription on a life-sized bronze statue of Will Rogers which stands on a pedestal which is strategically placed in the U.S. Congress, in the perfect corner between the rotunda and the chamber of the House of Representatives, where bills are proposed, the beginnings of new law. If you have watched news coverage of House members entering that chamber, likely, the news people are standing at the base of this statue. Why? It is the perfect place to catch a congressman unaware and to possibly snag a snatch of truth in an impromptu interview. The toes of the statue of Rogers are polished brass, worn down over time by elected officials who run their fingers across them when they are on their way to the chamber to vote. They do that for luck, and to make a promise to the great American that they will remain true to the American people that they represent in that chamber. Wow!

Will Rogers, born to a Cherokee family in Oklahoma in 1879, is classed as a vaudeville actor and later a motion picture star. He was a cowboy as well as a Native American by birth. He became a columnist, and by a combination of all of these things, he generously shared his remarkable good humor. Finally, he is called a social commentator, but I want to elevate that title to philosopher. He was the best kind of philosopher because he was known to so many people who saw him act or who read his newspaper articles, could make people laugh, and then, on top of that, he taught Americans to be good, honest, and moral. Lord knows America needs a journalist who can do that today! Sadly, we have no one worthy to cast a shadow on his bronze statue. Web search Will Rogers. Learn all that you can about him, and especially read his quotations. Here is one: "Live in such a way that you would not be ashamed to sell your parrot to the town gossip." I suppose that today's parrot would be private e-mail that everyone was able to read.

It seems that he lived his life as a grand adventure, stepping out in any direction, wide-eyed and grinning, seeking to experience all that he could. "I never met a man I didn't like," he was remembered to say. Indeed, he could write a column to chastise someone, especially a politician who had morally strayed, and do it tongue-in-cheek so that the subject was not vilified. In that sense, he did so much to shape America in the early 20th century to be a good nation filled with people who had a sense of decency. In his time, Americans were still mostly small town people who cared about each other. Will Rogers died while on an adventure in pursuit of a new pastime, aviation, in the wilderness of Alaska. Web search, but don't dwell on how he died. Take for yourself the goodness of how he lived.

There is highway marker placed at the western end of the most famous U.S. Highway known as Route 66. The marker is a dedication to Will Rogers, a footnote on this route which passes east and west through his home state of Oklahoma. He took it many times, sometimes going east and sometimes west. On the marker, find this inscription: "The first road he traveled in a career that led him straight to the hearts of his countrymen." Say a prayer of gratitude for Will Rogers.
