management issues are resolved by the invention of big data technology. Not only the data is being generated by internet, but also huge amount of data is being produced by different companies from sensors, computers and automated processes. Another source of big data is the use of cell phones, tablets, laptops and PDAs for accessing social networking websites i.e. facebook, twitter etc. Similarly space experiment technology and medical imaging technology is also producing huge amount of images…

same stomach contents were found on Chris’s shirt, the day he was found. Chris’s sister said she remembers he was eating cereal that morning. The detective concluded that the stomach contents found on the car bumper, and the shirt, are from the same source, and…

The Human Battery Do males or females produce the most electric current? Abstract The Human Battery Do males or females produce the most electric current? Abstract The purpose of this project was to determine whether males or females produce the most electric current. An aluminum plate, a copper plate, a micro ammeter, two lead wires with alligator clips, water, notebook paper, and pencil were used as materials. It was predicted that males would produce a greater electric…

Essay What welding type is favored above another? Instead of underwater welding, I should focus on Mig welding. They both are used all over and have different qualities that appeal to people in their own ways. These qualities have positives about the job, drawbacks about the job, different opinions, as well as comparisons about each that can be viewed differently by each person. Underwater welding is a different type of welding for me. It has many benefits that draws me to be an underwater…

and left to set. 10 µl of prepared DNA was pipetted unto a new microfuge tube with 2 µl of 6x loading dye. The solution was pipetted into the prepared gel next to a molecular weight and positive and negative controls. The gel was run with a high voltage buffer at 300V for 20 minutes. The gel was removed and visualised using the Gel Doc system. Gel Doc photos where analysed, comparing the DNA samples with the controls to determine sex and molecular weight of PCR…

“The machine does not isolate us from the great problems of nature but plunges us more deeply into them.” - Antoine de Saint-Exupery I relate to this thought in my quest to find sustainable technologies because the work of an engineer is to “enable the future” not merely to “foresee” it. As a mechanical engineer and a founder & head for a sustainable technology based start-up I realized the importance of technology enabled sustainability for a healthier…

everything else in a complex sample [X1]. This method had truly had a revolutionary impact on science with the sensitivity, resolution and the range of masses able to be measured [X12]. Most mass spectrometers are made up of a few different parts: an ion source (which…

Research for AS91172 Billy Barrow From Thompson 's Model to Rutherford 's Model By the time that Joseph John Thompson confirmed that Cathode Rays were made up of negatively charged particles in 1897. The groundwork for the idea of the atom had been in the works for many years. From ideas from Leucippus and Democritus from ancient Greece who first proposed the idea of 'atomos ' meaning “inadvisable”. This idea of the smallest thing went on largely ignored in favour of the ideas of Aristotle,…

Magnets are one of the fundamental items in physics. This paper is meant to provide a general overview of magnets and their uses, as well as an in depth look into certain aspects of magnetism and how they relate to everyday life. Most images of a magnet come to mind as a tiny object used for hanging things on a refrigerator. But other applications are much more useful in our society in general. They are used in all kinds of speakers, in many computer parts including hard drives (for recording…

The periodic table had been a key factor in many ways to finding new elements, like scandium, silicon, and neon. It has shown new ways those elements could help us by predicting certain elements reactions. While Dimitri Ivanovich Mendeleev is considered to be the creator of the periodic table, there were many contributions that helped the creation of the useful graph be achieved. Between 1817 and 1829 Johann Dobereiner was grouping elements with similar properties into groups of threes,…
