Paper is made out of trees because there are alot of them and because thay are also a renewable and recyclable resouce
If you have anything under 100 plants you get charged with 0-5 years, anything over that you can get anywhere from 5-20 years in jail. I got manufacturing with an intent to deliever and i had a pretty clean record and got 2 months jail and a year and a half of drug court but it depends on the state but those are the guidelines they go by as far as how much time you can get
How many trees does each UK family use per year in waste paper?
If an average family recycled all of their paper, this would save 3 trees worth of paper every 6 months.
Each person in the UK uses 15 trees worth of paper every year
Every year we need a forest the size of Wales to provide all the paper we use in Britain.
How many trees are used in cardboard?
Very few trees are used in the production of cardboard, because just about all cardboard is recycled. Cardboard is made by moistening and heat drying already used cardboard. It is first made into huge rolls of paper and then layered to form thicker cardboard.
How many paper plates can 1 tree make?
The typical tree can make about 1000 paper plates. Some trees will make more or less than this number of plates.
With advancing technology and intense competitions, companies will strive to provide wider varieties of goods and services. Companies will thus produce both simple and complex products. Complex products tend to consume more non-unit level activities. Examples of non-unit level activities are setups, inspections and equipment maintenance, etc. When there is a large proportion of non-unit level activities, plant-wide overhead rate and departmental overhead rates will result in inaccurate costing. This is because the two traditional methods use unit-level cost driver that cannot capture non-unit level activities with precision. An example of unit-level cost driver is machine hours, since every product requires machine time. Usually complex products are produced in lower volume than simple products. Since the traditional costing methods use a unit-level cost driver, simple products will have higher overhead costs than the complex products. The products will thus be priced higher. The complex products, which use more non-unit level activities are priced lower. Logically, complex products are more expensive than simpler products because of their more complicated production processes. These production processes involve more non unit-level activities. The inaccurate costing leads to inaccurate prices of products, i.e. overpricing the simpler products and underpricing the complex products. The overpriced products might lead the firm to shut down its production unit due to low demand. Similarly, the underpriced complex products will have unexceptionally higher demand. This will undermine the true profits made by the firm. Because although higher demands lead to higher sales, the revenue that the firm collects are, in fact, less than what it supposed to get, if proper costing method is used, e.g. ABC Costing. Companies will incur losses instead because of the high expenses incurred that are not captured in producing the complex products. Hence, the plant-wide rate and departmental rates are no longer adequate to use for costing products.

Diffence between ferritic stainless steel and martensitic stainless steel?
Ferritic stainless steel are magnetic, containing no nickel and not hardened by heat treatment. For example 409 and 430 stainless steel
Martensitic stainless steel are also magnetic and containing no nickel but hardened by heat treatment. For example 410 and 420 stainless steel
Does heat treatment increase the carbon content in carbon steel?
Heat increases the potential energy and temperature of steel.
What is the Hardness of 1018 carbon steel?
Between 121-137 on the Brinell hardness scale - which is quite soft. The end parts are generally case-hardened before use to 60+ Rockwell "C".
Are there killed carbon steel pipe-fittings?
Yes. Argon gas welding is often used for killed steel welding to inhibit the oxidation of the steel.
What is the difference between chrome plated and stainless steel?
Chrome plated is using electric plating method to have a layer of chrome plated on top of the metal, (usually iron or steel. ) because of the nature of the chrome it will prevent rusting of the surface of the metal.
Stainless steel is an alloy containing chrome and aluminum and many other traceable amount of metals, different grade of stainless has different ratio of contains and give different characteristics to the steel.
What is the ultimate shear strength of stainless steel 316 n 304 n 302?
It depends on how it is worked, but a minimum strength in tension is 80,000psi. In shear, it is 0.577 times the tension strength, or shear strength minimum = 46,000 psi
First of all, a stainless steel is a steel that has > 10.5% Chromium (Cr); this ensures development of a chrome-oxide that prevents further oxidation.
The 300 series of stainless steels differs from the 400 series in that the 300 series has both Cr and Nickel (Ni) - the 400 series has only Cr.
304 stainless steel has 18% Cr & 8% Ni.
316 stainless steel has 16% Cr, 10% Ni, & 2% Molybdenum (Mo). I believe this added Mo increases corrosion protection from chrloride-induced corrosion.
What are the difference between stainless steel and ordinary steel?
Some stainless steel is non magnetic, like the 300 series which contains a good bit of nickel which makes this series non-magnetic, but the 400 series does not have nickel and are thus magnetic, so you cannot differentiate between this series of stainless and regular carbon steel using a magnet. If the sample in question rusts easily, then it's probably regular carbon steel, though there are some high carbon steels like D2 tool steel for example, which have a high enough percentage of chromium (D2 has 11% to 13% generally) which make them 'almost' stainless and thus they don't rust as easily as a high carbon steel like O1, which does not have enough chromium (.50%) too inhibit oxidation and thus it rusts quite easily. The only other means to tell whether you have stainless steel or regular carbon steel would be by performing a spark test which could tell you whether you have stainless or regular carbon steel or sending a sample out for metallurgical analysis.

What is the equivalent BS steel of astm a36 steel?
BSEN 10025-3GRS420N give me the material composition number
How is high carbon steel used?
High carbon steel remains popular for a wide variety of uses. This type of steel is preferred in the manufacturing of many tools such as drill bits, knives, masonry nails, saws, metal cutting tools, and woodcutting tools. But that's only the common use
new study led by Children's Hospital Oakland Research Institute senior scientist, Elizabeth Theil, Ph.D., is the first to suggest that a small protein or heptapeptide (seven amino acids wrapped into one unit) could be used to accelerate the removal of iron from ferritin. The results of this study may help scientists develop new medications that dramatically improve the removal of excess iron in patients diagnosed with blood diseases such as B-Thalassemia (Cooley's anemia) or Sickle Cell Disease.
The study appears in this month's issue of the Journal of Biological Chemistry and was conducted by Dr. Theil and her co-authors Xiaofeng S. Liu, postdoctoral fellow at Children's Hospital Oakland Research Institute, Marvin J. Miller, Ph.D. and Leslie D. Patterson, a predoctoral student, both from the University of Notre Dame. The scientists knew that the ferritin protein cage had pores that could open and close. It was also known that chelators (a method to detoxify blood) removed iron faster when the pores were open.
"We wanted to prove a hypothesis that a small protein or peptide could bind to ferritin and could be used to regulate ferritin pores," said Dr. Theil. "Our hypothesis was correct. We proved that when a binding peptide of seven amino acids, a heptapeptide, is coupled with Desferal the rate of removal of iron from ferritin is eight times faster." Desferal is currently used to detoxify the blood of patients with iron overload and is a common therapeutic remedy.
Ferritin is a protein that concentrates iron in its inner core or 'cage'. It plays a critical role in understanding iron overload, which can lead to a variety of symptoms including chronic fatigue, weakness, joint pain and arthritis. If left untreated, iron overload can lead to serious problems, including diabetes, liver and heart disease.

What is plain carbon steel used for?
The various uses of carbon steel depend on the amount of carbon added to the alloy; for instance, carbon steel with the lowest amount of carbon is called wrought iron and is used for things like fencing. Medium-carbon steel, also called mild steel, is the type of steel that is used for structural purposes in buildings and bridges. High-carbon steel is used for springs and steel wires, while ultra-high carbon steel is called cast iron and is often used to make pots.
Is stainless steel ductile or brittle?
it is ductile. For hardened stainless steel it gets less ductile, but not brittle.
