    The legal issues in this case are: there is anywhere from twelve to twenty million illegal immigrants residing in the United States illegally. As far as the ethical issues in this case, well there are so many issues I wouldn’t even know where to begin. The fact that any business would intentionally make their working environment and so poor knowing that only illegal immigrants would tolerate working there without reporting it to any agency or the legal system is beyond unethical! Now that the legal system only requires employers to use the “E-Verify” system rather than making any illegal immigrant/person provide hard copies of their citizenship. Proof of legal status can now be passed off with false names that are given to employers make our government act irresponsible which causes them to not act ethical. The information that the person provides the employer may check out in the system but in reality is not legit; and is often overlooked because it can be without consequences to the businesses. Any business that would “depress” wages so low that it causes the people who legally reside in the United States to take a huge decrease in pay because illegal immigrants that “check out” or not… are willing to work for a lot less than what the company previously paid out in salary by “overlooking” the fact that they are really just paying lower wages to undocumented workers and taking jobs from legal citizens is unethical and just bad business in respect to our US economy. In 1986 by the law allowing the proposed immigrants legal status in our country while promising that there would be tighter border patrol that would stop the flow of undocumented workers when in turn the illegal immigrant population rose from three million to twelve (or up to twenty) million is entirely unethical especially on our country’s law enforcement and laws as a whole. The federal government has acted unethical by not taking action to stem…

    Chemical Stress Testing

    A chemical stress test is used when a traditional stress test (called a cardiac stress test) cannot be done. A cardiac stress test requires you to walk on a treadmill or ride a stationary bicycle until your heart rate reaches a level where your heart is “stressed”. You may not be able to participate in this kind of test if you have a condition such as a stroke. In this case, a chemical stress test is used. This test is used to help your doctor determine if you have any kind of heart condition causing the chest pain, if arteries to the heart have blockage or narrowing, identify an irregular heart rhythm, monitor the heart’s response to treatment or procedures, and plan rehabilitation after a heart attack.…

    Los Angeles Abrasion Test

    • 974 Words
    • 4 Pages

    Many tests have been developed to empirically characterize aggregate properties without, necessarily, strong relationships to the performance of final products incorporating an aggregate. The Los Angeles (L.A.) abrasion test is a common test method used to measure of degradation of mineral aggregates of standard grading resulting from a combination of action including abrasion and grinding. The standard Los Angeles abrasion test is ASTM C131: Resistance to degradation of small-size coarse aggregate by abrasion and impact in the Los Angeles Machine. Aggregate abrasion characteristics are important because the constituent aggregate in HMA (Hot Mix Asphalt) must resist crushing, degradation and disintegration in order to produce a high quality HMA.…

    The 'Aggregate crushing value' gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. It is the percentage by weight of the crushed (or finer) material obtained when the test aggregates are subjected to a specified load under standardized conditions, and is a numerical index of the strength of the aggregate used in road construction. Aggregates with lower crushing value indicate a lower crushed fraction under load and would give a longer service life to the road and hence a more economical performance. Weaker aggregates if used would get crushed under traffic loads, would produce smaller pieces not coated with binder and these would be easily displaced or loosened out resulting in loss of the surface/layer. In short, the aggregates used in road construction must be strong enough to withstand crushing under traffic.…
