than other shapes to produce the least amount of deflection. The differences and similarities seen in the slopes in Figure 1 are caused mainly by material choice and cross-sectional area. It is clearly shown that material changes the slope of the curve based on the three rectangular beams. All three have approximately the same cross-sectional area and approximately the same area moment of inertia, so the only variable that is changing is the material. This is significant because it shows that…
Friction is a crucial phenomenon in metal cutting which is very complex to model. It has a significant effect on the amount of power required for removing a given volume of metal, surface quality of the finished product, and the extent of tool wear. However, many studies assume no friction in the metal cutting process due to lack of experimental techniques to directly measure the coefficient of friction. Sticking and sliding regions are the two contact regions along the tool-chip interface. A…
the others. Each group boast a unique history, language, arts, traditions, beliefs, and other materials people make—whether tangible or not—that build their cultural mark. This mark is learned and passed through generation. However, the diffusion yield a vast increment of cultural groups that influenced each other, so some exhibit mixed cultures. In fact, people nowadays engage in popular culture which is a result of this series of influence. Popular culture offers people the liberty to adopt a…
Fed Chair Yellen Begins Fight to Save Her Legacy During 2016, I have emphasised how difficult it would be for the Fed to wean the US economy off near zero percent interest rates. This is partly due to the globalisation of financial markets and that overseas economies are in no shape whatsoever to withstand higher interest rates. Meanwhile, in recent weeks, it has become increasingly evident that Fed Chair Yellen is keen to avoid her legacy being judged as a disappointment via her inability to…
Introduction Mars colonization is a topic that has been brought to the attention of the media and of the public in recent years by aspirations made by companies such as SpaceX and the National Aeronautics and Space Administration (NASA). Several factors make it a topic worth discussing about, like concerns regarding the continuity of the human species and economical, technological and scientific worth of that endeavor. In this way, markets will suffer significant impacts once humans strive to…
Titrations of a strong acid or base with a weak acid or base yield results that greatly differ then a strong-strong titration. The strong-weak titrations allow for an in depth analysis of the half-equivalence point as well as buffers. The half equivalence point allows the calculation of pH from pKa, as they are both equal at the half equivalence point, proven by the Henderson Hasslbach equation. It was Henderson in 1908 that created an equation allowing for the logarithmic calculation for pH…
In this proposal, we report the design of two bioanalytical sensors: (1) a fluorescence optrode-based optical fiber sensor and (2) a carbon-based optically transparent electrode. The first provides a means for spatially organizing microorganisms to monitor their social behavior in response to different chemical environments. The electrode sensor enables the detection of signaling molecules that are responsible for, or a consequence of, sociomicrobial behavior. Upon their completion, these…
and to the relative share of wages at the margin. Since at margin no rent paid. Profits (in Ricardian sense) depend only upon the wages. With this definition profits can be determined as a residual over and above wage on that portion of land which yield no rent. However, it is not the actual wage that determines profit in the Ricardian sense, rather it is subsistence wage. In discussion concerning of the impact upon capital accumulation. Ricardo preferred to consider the portion of wages that is…
James Apostolico November 6, 2014 The Chemistry of Natural Waters Chemistry 111 Section: 005 Kareem Ali, Dima Alfawaz Stephanie Le Clair Introduction Water hardness is a way of defining the quality of water based upon the amount of Ca2+ and Mg2+ions that the sample contains.1 Water mostly becomes hard by flowing over weathering rocks which release these ions into the water. These released ions dissolve in water and then react with various elements, ions and compounds that…
contractors manufacture Nike products while NIKE JORDAN, converse, together with Hurley brands, does production. SWOT analysis: Strengths Nike has one of the strengths in product innovation. Nike has a usual culture of being ahead of the technology curve. This has helped the company to have an attraction of loyal followers together with influencing endorsements from…
