Case Study 14.1: Mackerel Economics in Federal Prisons Case study 14.1 poses the question how well do pouches of mackerel satisfy the six properties of ideal money, which include “durable, portable, divisible, uniform quality, low opportunity cost, and stable value.” (McEachern, 2012). We have to take in consideration that this form of commodity money was implemented after federal prisons banned cigarettes in 2004. Mackerel has replaced cigarettes and has satisfied all six properties of ideal money quite well. The pouches are durable, it is safe to assume that they rarely have the opportunity to expire because they serve as commodity money in federal prison among the inmates. The pouches are durable as well.
If it does then you waste your money because of what you paid for it is not working. 3. Explain why the walls and doors of refrigerators and freezers contain thick slabs of polystyrene foam. 3. This is so because the R- value of polystyrene foam is high so the heat from the outside of fridge or freezer cannot transfer to inside the appliance.
In the summer the original Crocs can be used as sandals but you can also buy Croc sandals that come in many colors and are very comfy. During the fall I lean more toward wearing the Croc clogs with a pair of socks that way your feet don’t stink and you still look fine. The winter is the only time when crocs can't be as handy but can still be used there are certain models of Crocs that have a sort of ugg feel to them inside the Croc but it's not guaranteed protection from the snow. It Keeps you warm though! In the spring it's the easiest time to wear crocs you can wear them with or without socks depending on the weather and they feel great either
Clearly the Salk Institute is a research laboratory that warrants these considerations when selecting building materials. The materials that make up the Salk Institute consist of concrete, teak, lead, glass, and steel. In my opinion these materials address the laboratories demands by being easy to maintain, as well as being durable allowing the Salk Institute to be built to last. I really enjoyed Kahn’s attention to detail when it came to the concrete work. Once the concrete was set, Kahn allowed no further finishing touches in order to attain the pinkish glow of "pozzuolanic" concrete.
Lead paint was widely used originally used for its favourable properties of long lasting durability and appearance, resistance to moisture and mould.1 Lead based paint also had the advantage being able to coat vehicles with a durable corrosion resistance which would last for many years. In the United States of America, the iconic yellow school bus was originally painted with a bright yellow lead based paint, since then other less toxic paints have been developed to reduce the danger of exposure. Children’s toys and goods were often painted using a lead base, because it was one of the few coatings that were durable enough to withstand rough treatment by children and be relatively affordable.2 Currently lead paint is still in production and is commonly used for industrial applications as well as in the military, domestic use has all but phased out. The toxic effects of lead paint have been for well over two thousand years, in ancient Greece a physician by the name of Dioscerides found a correlation between degenerative brain function and exposure to dangerous lead smelting fumes, a personal statement of his reaffirms this; "Lead makes the mind give way".3 During 1922 in Queensland the Health Acts Amendment Act of 1922 stated that: “114A(1) No paint containing more than five per centum of soluble lead shall be used or put within four feet from the floor or ground on the outside of any
Gold is also highly malleable and ductile which means it is able to be hammered into many shapes and can be drawn into long thin wires. The colour of this metal, a butter yellow with a metallic lustre, attracts many and is one of its most common recognised characteristics. Gold also has great infared reflectivity and has very low reactivity while in the presence of other elements. Gold’s resistance to corrosion is also what makes this metal so durable. 2.
Due to its flexibility, aluminum can without much of a stretch be rolled, stamped, drawn, spun, pounded or produced into any shape, making it the perfect metal for the car and aviation commercial ventures. While there are 7 unique sorts of aluminum combination, billet grille producers utilize either the 5xxx or 6xxx arrangement. The distinction between these two sorts is that they are fashioned from various composite segments. 5xxx arrangement aluminum utilizes magnesium as its rule amalgam, which makes it gentle to tolerably solid, and impervious to erosion. In the 6xxx arrangement, a blend of magnesium and silicon are utilized, creating a higher-quality aluminum with great erosion

How Concrete can be considered a Sustainable Building Material It is pretty much recognized that the production of 1 ton of cement released 1 ton of CO2 (Hostettler, 2014). Knowing this, it is reasonable to ask how concrete can be considered as a sustainable material. This essay will analyze this question considering the life-cycle of different construction materials and the increased use of recycled and substitution materials in concrete. Life-cycle One of the best way to compare the sustainability of different materials is through a life-cycle analysis. As cement usually represent only 10-15 % of a concrete mix (PCA, 2014), energy required to produce concrete isn’t so important.
The color variation and patterns on the slate slab together with the light and water, plays a vital role in the appearance of the slate slab fountain. Slate's qualities makes it a good choice for roofing because it can be cut into thin sheets, absorbs minimal moisture and stands up well in contact with freezing water. It is also used for interior flooring, exterior paving, and garden decor because it is more durable than synthetic materials. When installing
