Titanium is a low-density element (has 60% density of steel), that be able to be highly modified by alloying and distortion processing. Titanium is non magnetic, non toxic and has good heat transfer properties. Titanium and its alloys have melting points advanced those of steels, but maximum useful temperatures for structural applications usually range from 425-540C°. Titanium has good resistance to attack by most mineral acids and chlorides [ASM]. The combination of high strength, stiffness,…

quickly. Alumina is a chemically inert ceramic compound and sliding interaction of diamond coatings against alumina material is purely mechanical. Low and stable friction coefficient values of around 0.0804 were observed with the boron doped NCD coating. The stable and low friction coefficient of the boron doped NCD coating was attributed to the chemical inertness of the mating materials and also due to the…

Introduction: Selecting a pair of hunting boots is totally on the hunter and his needs. For serious hunters, who climb deep mountains, spend hours in the jungle and travel to colder regions in search of animals, choosing the right hunting boot is always essential.

research that I have found there are three main useful ideas on how to limit the use and waste of plastic water bottles and they are: reusing the bottles at home, recycling with a reputable recycler, and using refillable bottles when able. Using old material at home to create new goods has become a growing part of the US society mainly because of sites like Pinterest that show creative ways to reuse things that would normally be thrown away. This is the same even with plastic bottles, such as…

choice for pavers, bluestone tends to be extremely versatile. Not only for pavers, but bluestones is also used for garden paths, poolside, patios, driveways, and more. Most homeowners consider not only the price but also the safety aspects of the material before making a choice of a stone. Though this stone can be used indoors as well as outdoors, this tends to be more beneficial when used in the outdoors. This stone being porous can hold and bear water for a long span of time. If you are…

tonnes finish in oceans (Parker 2015). Only 15% of the total plastic production is recycled. The rest of the waste ends up in oceans, beaches, rivers and streets. In fact, the so-called Pacific Garbage Patch is constituted entirely by remnants of this material. Plastics are produced from fossil fuels, a source of clean energy, which causes emissions of greenhouse gases, and non-renewable because in a few years its reserves will be exhausted. But a solution to the problem of plastic waste could…

building is going to take place. The subsoil has to be able to carry these loads. The primary loads are natural loads, forces due to gravity. That are as follows; Dead load This is the permanent elements of the structure, a consistent load as the materials of the house will always be there. The architect can calculate this load. The objects involved are; • Floors • Walls • Ceilings • Slabs • Columns etc Imposed or live load This is the load of all the people in the building, for example in a…

Plastic Bottles Are Just Big Trouble “50 billion plastic bottles are used each year in America, that’s enough to wrap around the world 190 times,” (Leithman). Even though plastic bottles are popular now, when they were first created in 1947, they were very expensive and not many people bought them. However, in 1960, high-density polyethylene was made and introduced to the public. As the demand for plastic bottles escalated, consumers produced more plastic bottles for cheap, while selling the…
