Transportation of freight containing foodstuffs is often carried out across great distances by road and rail. There is a craziness that exists to supply the huge supermarket chains with produce up and down the country from massive , centralized farms. This is a practice that makes no sense. In a country such as the United States, there is ample farmland the length and breadth of the country with the means to grow most staple crops anywhere in the country. Yet a farm in one part of the country will produce crops that are transported by truck via road or train via rail to a supermarket hundreds of miles away. It happens every single day.

Most consumers have no idea where their food comes from, and quite frankly most of them don't care. If it’s on the supermarket shelves at the same price they bought if for last week, then that's good enough for them. Well, it’s not good enough if that freight of carrots spent all night on the road being transported from a farm several hundred miles away, when there is a perfectly good farm that also grows carrots twenty miles in the other direction. The ludicrous part of it is that the farm 20 miles away is probably supplying a different supermarket 300 miles away! Why is this?

Supermarket company buyers have a set list of farms where they source their goods from. Doesn't matter how far away it may be from some of their outlets if they're spread across the country, as is often the case. So a farm that may be 20 miles away from the first supermarket outlet will transport carrots or cabbages to that outlet and also to all the other outlets across the country, because they have an exclusive contract with that particular supermarket chain.

This practise may seem simple and logistically centralized, but it costs not just money to transport the freight of carrots and cabbages across the country, but it also costs in truck fuel usage and the pollution it causes. Not to mention that while the carrots may be fresh when they arrive at the first supermarket on the route, by the time they get to the last one, they're a day older.

The solution to this transportation craziness is obvious. That is to supply each supermarket with the bulk of its fresh produce from a local farm that diversifies to produce a wide range of food crops. That cuts down to the minimum any transportation costs and time. It cuts pollution and also ensures that the produce reaches the store while it is still fresh.

Will that happen? Well , in the case of some smaller store chains, they are seeing the light and adopting exactly this principal. But it’s still only on a very small scale compared to the mighty supermarket chains that continue to waste trucking fuel and money to keep up the pressure on their stranglehold on the food industry.

However, people can make a difference. Already, we've seen more organic produce in supermarkets than we did a decade ago because consumers started to demand it. If more consumers voiced their dislike of the way food is unnecessarily transported across vast distances when it can just as easily be sourced locally, then the supermarkets will bend to the power of a big voice of a large group of consumers. To sway the big supermarkets, it'll probably take voices in their millions. Bit it can happen. Enough people just have to want it to happen badly enough and they can make it happen.
Silicon is an element found naturally, it is gray and non-metallic, and has a distinctive attribute that has helped change the global world we reside in This characteristic is silicon's ability to conduct electricity.
Having the ability to conduct a power charge has managed to get the perfect materials for the semiconductor industry. Without this component, it is improbable we would have observed the trend in digital equipment and communication systems that has occurred during the last ten years. Silicon wafers must stick to stringent specifications based mostly after the work they will perform.

Factors To Consider When Choosing A Good Wafer

a.) Cost
If you're involved with an ongoing business that will buy wafers for the semiconductor market, there are a variety of important factors which should continually be at the forefront of your brain. The expense of the merchandise and their inherent quality are both crucial factors. Just like most commodities, the price tag on silicon does indeed fluctuate depending on other external forces, including the global economy , option of raw materials, as well as political decisions. It is vital that you become acquainted with the problems that impact cost to make sure that your business purchases the products at a cost that produces maximized profits.

b.) Wafer Specs
lt ought to be realized that we now have a variety of mechanized specs for the wafers sold today, take for example: size, width, and the variance of the width. For any wafer to operate correctly, it ought to be of an even specification, without available room for deviation or mistake. Other critical indicators are the flatness, edge, and bow, which should be even also. Each wafer must be completely smooth and without any markings caused through the manufacturing process and thin film deposition. Be sure you look for a company which produces only quality silicon wafers that stick to these specifications.

c.) Wafer Should be Particle-free
Every single silicon wafer should be particle-free. When there is an individual particle on the refined wafer this will impact its efficiency. For this good reason, calibration usually entails a traceable particle standard to ascertain quality and cost.

Silicon Wafer Classification

There are a variety of different levels used to classify wafers. The ones that are bigger than a hundred and fifty millimeters are usually s.
