action, while some countries failed to recycle their non-recyclabe commodities. There is a common conception that government officials should be responsible for the non-recyclable because citizens pay the tax. For example, one of the non-recyclable materials, plastic, will cause much harm If people forget to recycle them. Plastic bags will not be disposed in soil by itselves,and it may cost hundreds of years to break down in landfill. Moreover, too much plastic bags will cause the death of animals and

ABSTRACT The mechanical properties of composite materials are strongly dependent on micro structural parameters of the system. The evolution of microstructure depends largely on the cooling rate during phase change. Though the microstructure evolution depends on many process parameters, the final structure is decided by cooling conditions during solidifications. The mould material has a decided effect on the structure formation. The use of end chills during casting not only favours directional solidification

layers with one layer stiffer than other layer. How will the flexural modulus of the two specimens differ? Explain. (Hint, use Parallel and Series model to calculate the modulus to compare them. Assume the modulus of stiff material is 1X109MPa as and the modulus of soft material is 1X108 , and the volume fraction of each one is 0.5) Properties will be used for solving above problems: The modulus of S-glass is 85.5 GPa, the modulus of E-glass is 72.4 GPa, the modulus of Epoxy is 3.5 GPa and the modulus

excellent means of identifying “hot spots” or areas with organic material that could possibly support and accelerate microbial growth. The technology of ATP bioluminescence for hygiene monitoring has become increasingly useful because of it real-time capabilities, ease of use and affordability. It cannot replace microbiological testing but it is easier, faster and the results indicate cleanliness, (defined as the absence of organic material), rather than counting colony forming units of microorganisms

Work In Progress Title: "Inner Beauty" Size: 18" x 14" Medium: Charcoal, Graphite, Carbon on White Paper Step One: I am using charcoal for the background and graphite for the subject. I'm using Arches 140 lbs hot press watercolor paper for this drawing. This is one of my favorite papers. It has enough tooth to create dark values yet is smooth enough for very delicate textures. In this first step, I have cut out the shape of my subject(s) in frisket film and applied it to the paper. Then, I

IKEA has many organizational design elements that must function independently as well as jointly in order for the company to achieve success. The formalization design element describes how well the company creates and utilizes its written documentation of rules and procedures. The company adheres very strictly to these policies and procedures and has listed them very explicitly on their website for public knowledge. These policies include child labor laws, safety guidelines, and environmental guidelines

As a manufacturing engineer , I also in charge on choosing the right material to be use on the car , for the wheels of the car , I decided to use teflon wheels as it is light , strong and helps in reducing during the rotation on the track . we use double ball bearing for each of the wheels. We used the treated ball bearings which we had produce during the innovation. The axle we use is the carbon fibre axle because it is very light . The colour that we use is metallic colour using spray paint .
