How benefit of cold wealth condition

But in practice, this concept is often misused by not following any/all of the norms of the characteristics of acronyms. For example in the sentence "I am an M.B.B.S", M.B.B.S is not acronym because there are full stops between the letters. Likewise 'Viscom' (Visual communications) is not an acronym because the contents are not individual letters and it is written in lower case. Neither Rs (rupees) nor Mike (Michael) are acronyms and they are only abbreviations.

I wish to record some very crude usage of this concept even at international level.

There is a widespread saying that NEWS is an acronym for North, East, West and South which is absolutely wrong. News is a separate word meaning that new happenings. Needless to add, old happenings are not news but only history. They say that information are gathered from four directions and so abbreviation the four directions are branded as NEWS. That is not correct because not all the letters are in capital letters and the amplification need not have similar meaning with the words abbreviated. Secondly there are more directions than the four mentioned. News are obtained from space also.

Another wrong usage in this concept is the word LIONS. People belonging to Lions clubs International record that amplification of LIONS is 'Liberty, Intelligence and Our Nations Safety," the meaning of which God only knows. If 'LIONS' dot mean the animal king Lion, then how the children of the members are known as LION CUBS and their life partner, Lion ladies? Are they 'Liberty, Intelligence and our Nation's safety' ladies? One more important observation is that it is LION'S CLUBS INTERNATIONAL and not mere National. Hence the question of 'Our Nation's Safety' does not arise. It is clear that they are coining some words to accommodate the initials.

Thus Lions clubs are crucifying English words by an immature translation. (The author of this article was an active LION member for twenty years and he has spent considerable portion of his savings for Social services through LIONS Clubs.)

Certain people make their own abbreviations and amplifications. In college student elections, we have noted such usage frequently. Suppose a contestant's name is Sita there will posters saying Elect and select S (sincere), I(intelligent),T (Talented), A(Active) and so on as if Sita is an acronym for the four words mentioned. What if the opponents write as Sleeping, Intriguing, Torturous and Adamant?

Hence it is my fervent appeal to students and scholars of English language to desist from crucifying the language by misusing this concept of acronyms. Acronyms are used for brevity and clarity.. Sometimes they are used as 'secret code' also. Let us not misuse this concept narrow-minded purposes

It is a popular compound that is made with the help of elements like carbon and silicon. The chemical formula of this compound is SIC. It occurs naturally in the raw material which is known as the moissanite. In the year 1893, this compound or silicon carbide is produced in huge percentage for using as the abrasive material. The manufacturers combine grains of SIC together with the help of the sintering process to form a hard type of ceramics. They are used in various applications like the car clutches, vests, detectors and many more.

Apart from these usages, the compound is used in the semi conductor devices that generally work in the HV areas. The users can use larger crystals of silicon carbide with the help of Lely method. They are cut in the small pieces with the help of the SIC.

Carbide is a hard compound that is used in the carbothermal reduction of the element silica. Depending on the situations, the resultant SIC that is formed may be in the powder form or available in the ground mass state.

The reaction bonded carborundum has various properties. It is one of the refractory materials that high melting point. It is also having high thermal conductivity and thermal expansion characteristics. Moreover, SIC that is available in the market is hard in nature, excessive stiff and corrosion resistance. Carbide is also having some interesting properties like the semi-conductor features.

There are various commercial uses of carborundum. They are used in the engineering applications and available in three different forms like the silicon carbide, nitride bonded silicon carbide and the reaction bonded silicon carbide. There are various uses of silicon carbide. The very first form is that they are used in the refractory applications that depend on the manufacturing needs.

There are various advantages of using SIC. They are used in the electric voltage purposes. This compound is having HV acceptance than the original compound. SIC switches that are available in the market are to be fitted in various applications depending upon the requirements. It helps in reducing the system complexity, reliable to the users and they are also used as they are cost-effective. Silicon carbide works in the region that has high temperature that is more than 400 Celsius. Thus, when you require these above benefits, it is very important to buy the SIC.
Alumina Ceramic offers superior insulation properties for electricity along with great wear and tear resistance and high hardness but has a comparatively lower strength and the fracture toughness. It is the most mature form of the engineering ceramics. Most of the Alumina Ceramics is generally white. Some of them might also be pink which has about eighty-eight percent of alumina or brown that has approximately ninety six percent of alumina. The colour of the ceramic comes from the impurities in the raw materials or from the sintering additives.

Alumina ceramics that have superior purity are best for the environment where in the resistance to corrosive substances or wear and tear is required. These ceramics are also used in areas where the temperatures are very high and resistance to it is required as this ceramic is known to have a great thermal stability. For the alumina wear parts, the alumina ceramic is the best material as the ability to resist heat and wear and tear makes the ceramic ideal for manufacturing of components that are wear resistant.

Alumina is known to be an excellent electrical insulator having resistance to very high electricity. The great thing about alumina is the fact that the resistance to electricity increases with the purity of it. The more pure alumina is, the higher the resistance would be. Alumina also has a very high melting point and high hardness. The mechanical strength starts to reduce when the temperature goes beyond 1000 C. Hence, the resistance to thermal shock reduces because of the huge coefficient of the thermal expansion.

The high resistance to corrosion in alumina is derived from a great chemical stability. Alumina is slightly soluble in alkaline and strong acid solutions and absolutely insoluble in water. The alumina with superior purity is the main choice for the components in a wide array of industrial applications because of its ability to resist chemical corrosion. It has been proved that the alumina has high resistance to the corrosion caused by chemicals because of the lower solubility in chemicals.

The alumina ceramic is blended with the additives that work on enhancing its properties. A great variety of shapes and sizes of the components can be produced by using several varieties of the processing methods of ceramic like net shape or machining. High thermal conductivity, high resistance to heat, great insulator of electricity and high resistance to corrosion are a few factors why alumina ceramics is favoured amongst many manufacturers. Boron carbide is generally used in the bulletproof vests, engine sabotage powders and rank armors. They are also used for several industrial applications. This is definitely a hard material but it is definitely not harder than diamond and boron nitride.

This compound was discovered much earlier in the 19th century. This occurred from reactions of metal boride as a by-product. But the chemical formula for this compound is unknown. In the later times approximately in the 1930s, the chemical formula for the compound was estimated to be B4C. This material is slightly carbon deficient if one refers to the formula.

It is attractive as an absorbent because they have an extremely good ability to absorb boron carbide. The nuclear applications include shielding, shut down pellets and control rod. The boron carbide is often powered within the control rods to increase the surface area.

The properties of boron carbide:

Well, boron carbide as we have already mentioned before is quite hard. There is a cross section that especially makes the neutron absorption possible. There is very much stability that provides ionization of the radiations and most of the chemicals. As the third-hardest substance available, it is often referred to as a black diamond.

This material is p-type. It is also a semiconductor having electronic properties. The band gap of energy largely depends on the composition and the degree of order. It has many mid-band gap states but the most common band gap is estimated to be 2.09eV. This is responsible for the complication of the photoluminescence spectrum.

How is boron carbide prepared?

For the very first time, it was synthesized by Henri Moissan, in the year 1899. He has reduced boron trioxide in the presence of carbon from magnesium or carbon in an electric arc furnace. While if you are considering the case of carbon the reaction occurs at a temperature that is above the melting point of the compound. This also releases large amounts of carbon monoxide. If magnesium is used in the process then the reaction can be done in a graphite furnace. The byproducts of magnesium can be further removed by acid treatment.

What are the uses of boron carbide?

They are having multiple uses. They are used as abrasives, metal matrix composites, padlocks, cutting tools and dies, etc. They are also used in vehicle and personal anti-ballistic armor plating. The manufacturers find it safe to use it in the in brake linings of the vehicles, scratch, and water resistant coatings, grit blasting nozzles, scratch and wear resistant coatings and for many other purposes. Alumina, also known as Aluminum Oxide is the most well-known material commonly used as ceramic beads. It has a crystal appearance just like ruby and sapphire. It has been used in the electric insulation for over decades. Its exceptional mechanical properties like high strength and resistance against corrosion have made the material widely popular in the diverse domains of industries. If you are still not convinced about the beneficial aspects of this material, the below-mentioned points would most certainly change your mind. Let us take a good look at them.

Why are Alumina Ceramic Beads so popular?

Alumina is an excellent material, which has a wide variety of applications. It is a well-balanced matter that has durable parts, making it ideal for the sectors, where there are high-temperatures just like furnaces. It has certain distinguishing thermal, mechanical and other properties, which make it stable both physically and chemically. These amazing characteristics have allowed alumina ceramic to acquire widespread recognition among the manufacturers.

Apart from the above-mentioned aspects, alumina could also be used in a diverse range of clarities along with other additives that enhances the already existing properties of the material. Different ceramic processing procedures are applied on the material, which includes net shape formation or machining, in order to produce items of varied shapes, sizes and components.

Alumina based ceramic beads are considered to be the best possible product. Owing to the combination of a number of properties, it is able to make its name among so many insulating materials. Well, as we have discussed the individual properties of alumina, let us now move on to explain the distinct characteristics of alumina ceramic- a product as a whole. My oldest son is a soldier. He arrived in this life, the day before my 34th birthday, kicking and screaming like a banchee, and to be honest, he hasn't stopped. He'll take a good battle over the easy road any day of the week, but he gets things done.

As a toddler, his big plan for life was to grow up and be a cowboy. He loved to walk around in his Daddy's boots, and even though Daddy complained about it, Sean did it anyway. I remember telling him once that those were big boots to fill, and he said, "My feet are going to be bigger."

At the time, I laughed it off, didn't think much about it, and I spent a good amount of time helping him find ways to learn, grow, and become the independent young man that he is today.

He learned that choices have consequences.

When he was about seven we dug a pond in our front yard, and after it had been dug, he and his friends filled it full of rocks. The friends went home, and the next morning, his job was to take all the rocks out of the pond and stack them on the side so we could put the liner in the pond. Two days later, when his friends came back to visit, he shared his experience with them, and convinced them that since he had to clear out the pond by himself, they should help clean out the chicken coop. Choices have consequences.

Reading wasn't his strong suit, but he found alternatives.

He loved to learn, but he hated to read. He would beg his sisters to read to him, and listened intently anytime anyone read a book. He could memorize details faster than anyone I've ever known, and his memory of historical facts is second to none. He loved History, so he would find documentaries about history, and listen or watch those, then he'd spend hours studying up on the details of the documentary. Studying, researching was more interesting than just reading about it, and he was able to answer a lot of his own questions. Education became a game of challenge, research, and learn more.

Working to learn, learning from work.

On the job training became part of his process of learning, and he loved travel. He would grab any opportunity to travel and learn more. Apprenticeships are difficult to come by, but he found three ways to get apprenticeships, and learn as he worked. Farm jobs were plentiful, and he loved working in the country. Political training, jobs, and working with political leaders became a strong second alternative way to learn history. He would spend hours pouring over historical journals and documents.
