CHAPTER I THE PROBLEM AND ITS SETTTING Introduction Throughout the 20th century‚ plastics have been an essential part of the market industry. Most plastics are a combination of other organic and inorganic compounds; 20% of the content of a plastic is composed of additives. Biodegradable plastics are usually derived from proteins such as those that are present in a potato plant. Polymers are large molecules consisting of many repeating units‚ called monomers. Polymers can be made out of starch

Well‚ if you do there is a chance that your containers have flaws and defects that are noticeable to the human eye. There are defects that do not get in the way of using the containers but for quality purposes‚ it still is a defect. This paper will show a 3-sigma control chart for the production process for using the new and standard

Sustainability Issues with Plastic Bags A plastic bag is used for 5minutes on average but requires more than a thousand years for it to decompose (Sharma‚2008). After decomposition‚ the tiny particles continue to contaminate our water sources and threaten wildlife (West‚ n.d.). Yet‚ the global usage of plastic bags hits an unprecedented annual rate of 1 trillion (Facts‚n.d.)‚ with Singapore contributing 3 billion in 2011(Tay‚2012). Hence‚ it is vital that we pay more attention to our environment

breast augmentation‚ liposuction‚ and tummy tucks [1]. As we consider under what circumstances plastic surgery is appropriate for teens‚ it is important to recognize that very few studies have been conducted to examine the risks for teens of these increasingly common procedures.

Multicomponent distillation 1) Mass balances The feed flowrate is 350 kmols hr-1 and the feed composition is known: 48 mol% propene‚ 50 mol% propane and 2 mol% butane. The distillate stream composition: 99.9 mol% propene and 0.1 mol% propane. The bottom product stream contains 0.5 mol% propene but the mole fractions of propane and butane are unknown. Therefore‚ mass balances are carried out around the distillate column. Overall mass balance: F=D+B Component mass balance for propene: xFF=yDD+xBB

| Latent heat is a science term used to describe the amount of energy that has been absorbed or released when a substance goes through the process of changing states. | Latent Heat of Fusion - heat absorbed by a unit mass of a solid at its melting point in order to convert the solid into a liquid at the same temperature The heat absorbed as a substance changes phase from liquid to solid‚ a process called fusion or solidification. For water‚ Latent Heat of Solidification - heat liberated
