Particulate

into your lungs, they can profuse directly into your bloodstream, carrying with them whatever chemicals are attached to the sediment. That would be Cadmium, Arsenic, and Selenium.” (Tim Krantz Breaking Point 00:31:12 - 00:31:40) These microscopic particulates can affect your entire body, and cause serious medical emergencies ranging from heart disease, neurological damage, and kidney failure. All of these problems are happening now, before the Sea has fully dried up. If this problem isn’t…

regulations passed, the use of diesel exhaust fluids in maintaining cars and trucks that can produce large amounts of exhaust was mandated. Diesel exhaust fluids are not needed in a diesel truck, because by the time the diesel fluid hits the Diesel particulate filter, the diesel is disintegrated. The diesel exhaust fluid is burned at 600 degrees before getting to the filter, usually burning up only to temporarily lube the gears like lotion to skin. Diesel fluids are just another example of…

This essay examines the implications of waste in design and manufacturing with regard to the nature and future sustainability of practices considered modern by contemporary standards. Practices, such as CNC (computer numerically controlled) machining and additive manufacturing such as 3D printing, are the benchmark for modern manufacturing; 'In the domain of manufacturing, computer numerically controlled (CNC) technology is a major contributor to the production capacity of the…

Statistical analysis Each defect was considered as a statistical unit. Primary study outcomes were changes in CAL at the six-month evaluation period. Descriptive data that included mean ± standard deviation (SD) were calculated for clinical and radiographic parameters at baseline and 6 months. Following this, the data were subjected to statistical analysis using the Wilcoxon signed rank test for intragroup comparison and the Mann-Whitney U test for intergroup comparison. The level of…

Introduction: An electric toothbrush is a toothbrush that makes rapid automatic bristle motions, either back-and-forth oscillation or rotation-oscillation , to provide oral cleaning service, removal dental plaque from the surface of teeth. Electric toothbrush generally powered by rechargeable battery or disposable battery. The functional unit for the electric toothbrush is 3 years per use where 2 times per day. The functional unit for the replaceable brush head is 3 months per use. We will…

This is done by attracting and/or trapping the pollutants in an air filter. Heating and air systems have built in slots to fit air filters at the supply air ducts to reduce particulates from building up in the duct work and throughout the building. These are typically single-use, single-stage filters that vary on a scale between efficiency and effectiveness. There are also larger whole building air filter units that are much more…

How big is ‘small’? Is it a grain of sand, a speck of dirt, a strand of hair, a drop of water? Is it the size of what humans can see, with our own two eyes? Is ‘small’ bigger than that? Or is it much, much less? For years, people tried to discover the definition of small for the scientific world. Does ‘small’ act the same way as ‘big’? Can the movements of ‘small’ be described and categorized? All of these questions were analyzed over and over by scientist for hundreds of years, to form what is…

Fracking, also known as hydraulic fracturing, is a type of drilling that uses water, sand and chemicals, shot at high pressure, to release energy resources trapped inside rocks. This recently new technology for drilling allows areas that were previously inaccessible for drilling, like very concentrated rocky areas, to now be opened up through fracking to obtain natural gases and oil. The water solution used with this drilling technique produces almost the same amount of “sludge” as an after…

As many students are making there way back to school we often ask ourselves why some schools have year round school and why some schools have a traditional school calendar. I believe that year round schools are a great thing to have as a school calendar. There are many benefits that come along with the year round calendar such as more family time, and better more balanced calendar. Also at the same time there a many loopholes that come with the year round calendar such as there is a lot of…
