Research the use of copper as microbial control agent.
If you could only choose one chemical agent to use in your home, which would you choose and why? Why would you not choose some of the other choices?

Expert Solution

Cold sterilizations refers to the immersion of heat sensitive instruments into the microbicidal solutions like glutaraldehyde, orthophosphataldehyde, hydrogen peroxide etc to get rid of microbes.

This type of sterilizations belongs to physical method of sterilization apart from chemical method.

Gamma radiation is known as cold process because the temperature of the product being processed doesn't get increase significantly. Often suitable for heat sensitive items.

Yes I do think that the radiated foods should get labeled due to the fact called right to information and to understand the effect of the processed product. Whether it has been sterilized or disinfected where two completely different stragies are applied. Also to ensure the safety of the operator or customer.

Heavy metals like copper, nickel and zinc coexhibit it's antimicrobials activity. Where, the most common copper sulphate is the algicide used to control the algal growth in swimming pool and fish tank.

When copper sulphate interacts with the bacteria the oxidized copper atom's break down the cell wall. Then, a gradual pull is generated due to which electrons from the atom gets extracted out respectively, eventually leading up to the death of the bacteria via disruption in osmotic pressure, breakdown of cell wall and leaking out it's cellular contents.

One chemical agen I would choose for sterilization would with in consideration of the following conditios like,

Feasibilities of the product/ agent and cost effective ness validated and authorized by the FDA. And so the chemical agent would be vaporized hydrogen peroxide because it does full fill all the conditions and recent studies suggest that it shows a quality function as sporicidal activity.

Why is lease financing sometimes referred to as off-balance sheet financing? It appears likely that the FASB and IASB will require all leases to be capitalized, even those that are now classified as operating leases. In fact, they have agreed that the leases should be shown on the balance sheets, but they are still debating how to recognize the lease-associated expenses on the income statements. This could have a huge impact on many companies’ financial statements. For example, Credit Suisse...
