Essays on Polystyrene

Abstract

Materials exhibit different chemical and mechanical properties such as strength and durability. Combining different materials to form a material composite enhances their individual properties in different measures. In this experiment, the mechanical strength of composite sandwich structures was investigated through bending. Four samples were investigated for their properties on bending and strength. Three of the four polystyrene beams were reinforced with paper while the fourth beam was investigated without paper reinforcement. One of the beams was bonded with construction paper on one side; the next bema was bonded with construction paper on both sides while the third beam was ...

Introduction

The research is typically based on the research questions. Punch (1998) identifies the main reasons for setting a research question. The research questions help to organize and direct a study, and keep the researcher focused; they set the boundaries and framework for the project, and designate the data necessary for the project. The research has to provide the reliable results and conclusions, irrespective of the area. Therefore, scientific and social research have to be based on the real-life data and the appropriate data processing methods. The data should be obtained using the procedure of statistical sampling and tested for ...

Chapter 11, pg. 427: Denver Goes Alfresco

- What type of problems was the consolidated city-county government of Denver, Colorado, experiencing with documented management before instating the Alfresco ECM system?

Before the introduction of the Alfresco ECM system, the consolidated city-county government of Denver, Colorado experienced many problems with the documented management system. Before introducing the Alfresco ECM system, more than 70 of the consolidated city-county government used 14 different documented management systems, none of which could communicate or interact with each other (Laudon & Laudon, 2012).

The information Technology department had to manually supervise many stand-alone autonomous IT units with their own systems and standards. Using a decentralized system created problems, including document sharing, document security, and the ability to audit record keeping functions, especially financial records and scanned ...

Jainism and Buddhism preach and believe in respecting living beings that include not only human beings or animals, but plants, insects, water, forests, creatures of the sea and water, and everything that grow. This is the science part of the environment which is balanced by all living creatures including air, water, forests. It is ecological science as it could be verified by observation, experiment, and reason. Every tiny creature, plant, water, air, and insect, plays an important role in the maintenance of the ecological balance, and the argument can be proved (Clowney and Mosto). This essay delineates environmental and ...

Forensic investigations have gained widespread application by law enforcement agencies during the analysis of a crime (Tewari and Ravikumar 2000). Forensic experts have a tough task because they have to use samples collected from a crime scene to reveal the culprits. In this case, the investigator has to determine which of the two companies (A or B) is responsible for the pollution that was reported. The samples that were collected have been analyzed using Fourier Transform Infrared (FTIR) spectroscopy. This form of spectroscopy is employed to produce an infrared spectrum of not only photoconductivity and emission, but also absorption of a substance ...

Introduction

Tensile testing is usually conducted to select a material for its application, quality control, and to forecast how the material is likely to react on deployment of different types of forces. The properties evaluated through the tensile test include the ultimate tensile strength, the maximum elongation, X-area reduction and so forth. These evaluations facilitate determination of such properties as Young’s Modulus, yield strength, Poisson’s ratio, and the characteristics of strain hardening [1. 2]. Tensile testing on glass fibre is, thus, performed to determine the quality of the material it contains, and to ascertain its suitability for various applications.

Introduction

DineEquity Inc., formerly known as the IHOP Corporation, is a company that manages over 3600 restaurants under the brand names IHOP (International House of Pancakes) and Applebee’s Bar & Grill. Based out of Glendale, California, the restaurant chain operates both brands on a franchisee model and is one of the largest food retail chains in the Full Service Restaurant (FSR) business (DineEquity, 2014). Unlike its competitors serving pizza, burgers, burritos and coffee among other eat-on-your-feet snacks in the Quick Service Restaurant (QSR) format, DineEquity’s restaurants promote the full dining experience of a restaurant where the customers can ...

AFFIDAVIT OF [NAME] [DATE]

[on separate page] I [#say on oath #affirm]: I am currently employed as an Environmental Forensic Scientist with the New South Wales Government. I have held this position since 2002. I obtained a Bachelor of Science (Forensic Science) degree from the University of Western Sydney in 2001. I have read, understand and will abide by the Expert Witness Code of Conduct. I was requested by [requester] to determine the composition of the material present in the environment, the source of this material and the level of environmental harm associated with this material.

It is hard to imagine a modern life without polymers. They are literally everywhere. What makes them so useful and unique? Chemists look inside the structure of a matter in order to explain specific chemical or physical properties. Polymers do have unusual structures. Their large molecules consist of particular segments that are repeated by some pattern. The segments are called monomers. As a result of polymerization, monomers completely change their properties. For example, polyethylene (-CH2-CH2-)n, “the largest tonnage plastic material”, is a waxy solid polymer (Nicholson 6). However, ethylene by itself is a gaseous matter. Even though man-made polymers were introduced relatively ...

Application Assignment #1

It is surprising that even though expanded polystyrene is so abundant, it is not recycled as much as the other plastics. Expanded polystyrene makes the containers that hold our foods, used as packaging material, used to provide insulation in our homes. Yet, expanded polystyrene is not recycled more. In my opinion, this has to do with the structure of polystyrene. Part of why polystyrene is not recycled more is because it is so light in weight. It makes up only 0.01% of total municipal solid wastes in terms of weight. However, the biggest impediment to recycling expanded polystyrene ...

Abstract

This paper clearly presents and defines the numerical study on how hollow building block operates to suppress the convectional currents and reduce the amount of heat flux transferred across the petition of the building wall. The configuration and weight of these blocks have made them to fully be utilized in building the facades. The air filled cavities (hollow cells) together with the small cross-sectional area geometry provides an appropriate elevation for the building block. The hollow polythene bars inserted in this bricks also helps to reduce the heat by about 36% depending on the petition number (Mejad 2006). ...

Research Question

Polystyrene is a very commonly-used material in the food and consumer electronic packaging industries. This paper will revolve around the research question “can polystyrene have other uses aside from its common uses?” The HIPS will be of particular importance here because much of the paper will revolve around the use of HIPS, how it is used, and how it differs from typical polystyrene. HIPS, which stands for High Impact Polystyrene is used in the research and development and manufacture of mechanical prototypes and other tools that are often subjected to high impact environments, stress, and tension. It is one of ...
