Plastic Literature Reviews Samples For Students

Life cycle analysis may also be referred as life cycle assessment. It may be defined as a systematic tool or technique that evaluates the environmental aspects of a product as it gradually moves through all its stages of the life cycle. This implies the development from raw material extraction, through to the processing of the raw materials, manufacture of the final product, distribution of these products, their use, the repairs done to them and the maintenance that they require and lastly its disposal or recycling. The main importance of the LCA process is to reduce the environmental impacts of the products ...

The Cloud for Digital Photography

CONVENTIONAL PHOTOGRAPHY: STORAGE & MANAGEMENT ISSUES
The advent of photography in late 1830s (Roosa, n.d.) has mandated later introduction and development of memory storage methods. The capacity for cameras to preserve in photographs personal and collective memories has made permanency a more urgent issue as photographs became household collectibles. Moreover, as development methods improved, older photographs (developed using outdated methods) required more maintenance during storage, particularly photographs produced by acetate negatives, chromogenic color film, polyester film and instant color print processes (Roosa). The deterioration of photographs by poor environmental storage conditions, poor storage enclosures, inadequate handling and shelving conditions, and ...

Introduction

The above quote alludes to the pliability and the malleability of plastic. Plastic is defined by the online version of the Merriam-Webster Dictionary as a synthetic material which is comprised of a variety of organic polymers which can be moulded into a shape while soft, and then set into a rigid, yet slightly flexible form. Glass fibre reinforced plastic (GFRP) is plastic which has been reinforced or strengthened by the use of glass fibres. This composite material has been used in the construction of large-scale items such as luxury boats, missiles, and tanks, and small-scale items, such as tubs, fans, hoods and scrubbers [ ...

Introduction

Thin films are in use since ages, and in old times people used to beat gold with hammers into thin films about less than one μm thickness and then used this thin film for gold coating of different stuffs. Thin films are used in many materials and do use them in daily life but are not aware of it. If one wax cars or paint homes that mean, they are applying a thin film.

Bulk Material VS thin film

Bulk materials are those materials that are mined. They are referred to as Bulk solid in mining and mineral industry. The material that can be stored ...

Abstract

Maintaining a highly effective waste management system is an important part of being a clean and green city. While this may not be the top priority for some countries, especially the developing ones—because keeping a clean and green city can be costly; there are countries that are making long term investments for a more effective waste management system in the future. This can be evidenced by the fact that even countries like Qatar and the city of Dubai are finding it hard to find the political and economic will to develop and enforce environmental law and regulations. If ...

Abstract

Microscopic analysis of materials is generally complex; hence engineers always look for alternative methods of analysis, by appropriate modelling. In specific, studying the damage of materials is important in almost every discipline of science/engineering/technology. Material damage includes the beginning, advancement and fracture of materials. The most important tool so far, used to analyze this damage, is called damage mechanics which relies heavily on continuum mechanics. It encompasses useful theories for the representation, modelling, and analysis of material damage. Broadly speaking, damage mechanics utilizes state variables to show the effects of damage. For instance, the variations in stiffness, and the ...

Introduction

Waste management refers to the process of collecting, transporting and disposing trash, sewage and other waste materials. There are different sources of waste including residential, industrial, commercial, institutional, construction and demolition, municipal, agriculture and manufacturing and all these waste products whether solid, gaseous, liquid or radioactive come under the realm of waste management. Due to the rapid growth and fast development in Australia, the country has produced waste on humongous amount. As per the data provided by Australian Bureau of Statistics, the growth of average annual rate of waste production in Australia is about 5.4% between 1996-97 and 2006-07. ...

Recycling is the process of making use of a product more than once in its life cycle before final disposal. This means that a product is used and then after the use, it is treated in one way or another to enable its reuse. Recycling is very important since it allows for reduced initial product which would have resulted in increased resource use and exploitation. From this perspective, it helps in economizing on resources and ensuring proper exploitation. Closely related to this is environmental conservation associated with recycling. From statistics, recycling helps in ensuring that the environment is conserved and less ...

John Locke’s Second Treatise of Government

Disproportionate and Unequal Possession of the Earth:
John Locke’s Second Treatise of Government

In John Locke’s Second Treatise of Government, Section 50 says that “by a tacit and voluntary consent,” men “have agreed to a disproportionate and unequal possession of the earth” (Locke, 1690, p. 19). Whether or not gold or money is a good representative of real wealth in goods or services and that man has made this tacit and consensual agreement for “disproportionate and unequal possession of the earth” is a debate that scholars continue to debate. Locke’s writing invites inquiry; his ideas concerning possession, consent, wealth, ...
