was clear from the data obtained by polarized light microscope (Figs. 4G and H) that the Haversian system is found as an individual canal system, the boundaries, which are marked by an occasional very faint line representing what has been called the cement line by Cook et al. [47]. Osteocytes, found in cavities (lacunae) within the matrix, were noticed. Dark precipitate in the form of a thick black line may indicate the presence of calcium phosphate in…

While tap water is available to many people, it is superior to bottled water in many ways. Some bottled water companies get their water from sparkling springs, but more than 25% of it comes from a municipal source (Jemmat). Price is another factor, compared to the price of gas today it costs more for a liter of bottled water than the same amount of gas. Tap water also creates a much more dependable source of water. With the use of tap water also takes away from the 81.7% of plastic bottles found…

During my graduate studies, I plan on studying aerospace engineering, with an emphasis of materials. Specifically, how materials behave and endure in extreme conditions like high radiation, high and low temperatures, and long durations of vacuum exposure. Once I graduate with my PhD in Aerospace Engineering, I will continue to conduct research and teach students…

Over the years, the industries of structural, mechanical, aerospace engineering, materials science, medicine, prosthetics, and many more have called for stronger, lightweight, low maintenance materials to withhold the stresses and loads that come with everyday usage of materials. Material scientists and engineers have studied and manufactured composite materials to cater to the needs of these various industries; however, composites have limitations as well. Many composites need repairs after…

ground quartz particles. Fig. 9 described water reduction effect as adding crushed quartz filler (QF) to MgO-SiO2 binary system to maintain a fixed flow of MgO-SF-QF ternary system (Series 3, 4, 5). It is obvious that the replacement of cementitous materials by crushed quartz filler improves rheology considerably, expressed by the consistent reduction of water content while maintaining a fixed flow of…

water absorption and smooth texture of finely ground quartz particles. Fig. 9, 10 described water reduction effect of adding crushed quartz filler to maintain a fixed flow of MgO-SF-QF ternary systems (Series 3, 4, 5). The replacement of cementitous materials by crushed quartz filler improves rheology considerably, expressed by the consistent reduction of water content while maintaining a minimum flow of 120-125 mm for workability. The amount of reduced water is proportional to the increase…

CHAPTER 1 EXECUTIVE SUMMARY TARPS recycles tarpaulin waste into bags. The bags are made out of tarpaulin, making it thicker than an average plastic bag and cannot tear apart easily like a paper bag would. Tarpaulin in nature are water resistant therefore the bags will not be affected by wet products and it will not melt when exposed in the rain unlike paper bags. If food was spilt in the bag it would be easier to clean it off or if the shoes put into it are muddy, cleaning the bag would not be…

chemistry, Mathematics, Thermodynamics, Heat Transfer, Material science etc., Tribological problem leads to the reason of metal failures than the mechanical problem such as fracture, fatigue and plastic deformation. 1.6.1 Friction Friction is the opposes that the motion (either sliding or rolling) of the object. This oppose force acts against to its motion is called friction force as shown in fig.1.7. The friction is not a property of material, but it is a system response. The ratio of…

MANUFACTURING COSTS: Functional Elements: The baby stroller is mainly composed of three materials: Nylon (woven, as fabric) Plastic (injection molded, for plastic parts) Steel (tubing, for frame) Fasteners are included in the assembly of different components of the strollers. The stroller would have to be manufactured on an assembly line. The fabric weaving and seat making, the plastic molding and the frame can simultaneously be manufactured in their respective work areas. Following are…

Written exercise Paragraph 1 Iron phosphate, FePO4, has a very similar structure as quartz. Quartz has a trigonal lattice structure with space group P3121 (group no. 152). Similarly, at temperature below 980K, iron phosphate exists as α-FePO4, which also exhibits trigonal lattice structure with space group P3121 in which iron, phosphate and oxygen occupy Wyckoff position 3a, 3b and 6c respectively. In quartz, every silicon atom is connected to four oxygen atoms to form a network of…
