There are many opportunities to reduce one’s consumption and to better manage one’s waste by taking advantage of the establishments in Ottawa designed for such a purpose. Bulk Barn is an excellent store for those seeking to reduce, or better yet, eliminate, all plastic products from their life. One need only bring a reusable container to a Bulk Barn location, and then fill it with a large variety of grains, flours, spices and dried beans, all while foregoing plastic packaging. Not only is…

As you consume bottled water, you are also taking the risk to get cancer and various reproductive damages. Human body need water, it is our biological needs. However, people choose to drink bottled water is just for them to meet their secondary needs. If you could choose between bottled water and drink water fresh out from the tap, I believe you would go for bottled water. No doubt that our body needs water to survive. In US, most of the people have the access to tap water, but there is a large…

This lab module covers the subjects of optical spectroscopy of gas discharges and bond stiffness of materials. Optical spectroscopy can be observed using different types of equipment, such as, a spectrometer, a light collecting fiber, and tubes of certain types of gas (He, H2O, H2 and O2). The data collected displays the peak wavelengths for each of the gases, which can be used to determine the energy released when the electrons change energy levels. Overall, it was interesting to see how…

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…

due to various reasons: Uncertainties in loading or environment Defects in material Inadequacy in design Deficiency in construction or maintenance The strength of materials can be increased significantly. But sometimes this comes at the cost of reduced ductility of the material. For example, strength of steel can be increased by manipulating the microstructure. But this increases the brittleness of the material. Thus, a member can fail catastrophically due to crack formation and…

strengths that materials can be tested on: Comprehensive strength and Ultimate Tensile strength. Ultimate Tensile strength is measured by how much stress can a material withstand, while being stretched or pulled apart before breaking, while comprehensive strength is how much van the material resists while being pushed in (together). There is also a Yield Strength- the point at which the material starts to slowly break and cannot come back to it’s shape. Before the yield point of a material, it…

CHAPTER- 5 ANALYSIS OF STEEL LEAF SPRING ________________________________________________________________ The aim of this analysis is to study the multi-leaf steel leaf spring under loading conditions and verify those results within the allowable limits. ANSYS software is used to analyze the stresses and strains by performing static analysis for the given leaf spring specifications and modal analysis is performed to determine the natural frequencies and mode shapes to asses the behavior of the…

AC 2.3: Explain the method of making titanium alloy and investigate how the composition and structure of metal alloys, polymers and poly-matrix composites influence the properties of the parent material. 1. Extraction process. 2. Melting process. 3. Storage process. Extraction of Titanium by Kroll process: First titanium ore Rutile (TiO2) is taken. Rutile is converted into titanium sponge by the following process: Titanium tetrachloride (TiCl4) – a colourless compound is obtained as a result…

We often hear of zero plastic campaigns and may even find many stores that have implemented a no plastic system in their stores. These is because one of a major cause of pollution is the littering of plastic and the increasing plastic problems affecting everone around the world. Plastic has been known to help us in a lot of ways as it is used as a convenience such as packaging food, plastic bottles, wrapper, disposable forks and even as to contain all our groceries in one plastic bag. It is easy…
