Alpha particle

were able to observe that when the cosmic rays collided with atoms in our atmosphere, the nucleus of the atom was prised open by the energy created. This then revealed many short-lived particles within the nucleus. However, these could only be seen in tracks left behind in sensitive detectors. There were many particles found such as muon, which behaves like and electron and is 210 times heavier. There is also the pion which is a little smaller than the muon as well as the kaon, which is just…

Fig: Schematic representation of LHC and it's detectors The primary objective of LHC is to answer the following questions: 1. Why some particles are heavier than others? If the Higgs mechanism is valid? 2. If the super-symmetry theory is valid? If yes then if super-symmetric particles exist? 3. If the concept of dark matter and dark energy correct? 4. Why our universe is made up of matter only? 5. What was the state of matter in the early universe? 6. What will be the properties…

Dogs are our best friends. Would you really want to harm you friends? That’s what Cesars method insists on doing to our canine comrades. Mark Derr should be considered correct about his accusations about dog trainer Cesar Millan because his methods harm the dogs, fails to produce lasting results, and overall, is faked by Cesar Millan. Cesar’s method should be considered wrong because it inflicts emotional and physical harm on the dog. This is apparent when Mark Derr writes “...his…

I found out about Particle Acceleration when I went to the United States Air Force Academy Summer Seminar in a class where we learned about propulsion. The topic covered was electrodynamics and it related to a particle accelerator. I have researched the particle accelerator online and watched videos over the CERN, largest particle accelerator in the world. I would like to further my studies in this topic so I can develop a large understanding of exactly how and why the particle accelerator is…

1. Most aquaporins have a similar structural arrangement, consisting of a similar fold. This fold contains helices encasing a small water-conducting channel where water is able to arrange in a singular line. There are cytoplasmic and extracellular loops immersing into the membrane through opposing sides, and form two smaller helices creating a psedo transmembrane segment. Within the membrane, there are four aquaporin molecules forming a homo-tetramer, creating a fifth channel; the channel is…

The Large Hadron Collider (LHC) is a particle accelerator made of superconducting magnets, built on September 10th, 2008. It can be found between the border of France and Switzerland, near Geneva, 100 meters underground. The Large Hadron Collider is a machine that was built with the ability to accelerate subatomic particles to very high speeds, which requires chilling the magnets to ‑271.3°C. This is done through the use of electric or electromagnetic fields, two hadrons are sent through the…

Particle size distribution Introduction The purpose of this lab was to determine the particle size distribution of a particular soil sample by carrying out sieve analysis and hydrometer analysis tests. For the sieve analysis test, a graph for percent finer versus the grain size was plotted from the data collected. The graph was used to determine whether the soil sample was fine-grained or course-grained. Calculations for uniformity and gradation were then done to determine whether the soil was…

Sigma–Aldrich, St. Louis, USA. Size 3 hard gelatin capsules were kindly donated by Capsugel Co., Ltd., Tokyo, Japan. Fresh Milli-Q water was collected and filtered through 0.45 μm membrane filter before use. Preparation of powders by spray-drying Powder particles were produced using a Buchi B-290 Mini Spray-Dryer (Buchi Labortechnik AG, Flawil, Switzerland) with a high performance cyclone in a closed-mode. Feed solutions of kanamycin (as sulphate) or/and rifampicin were prepared in a co-solvent…

Why do you feel that you are the best qualified applicant for this scholarship? I am applying for this scholarship to further my education. I privileged to be attending Ferris State University, and earning my degree. When I think of a degree, it is not just something that is required to get a job. A degree is furthering your knowledge in subjects you want to know more about. The best thing about education is that is there is no limit, and no one can ever take your knowledge away from you.…

maneuver played a major role on the patellar reflex. One of the prevailing hypotheses has to deal with the alpha-gamma co-activation theory. It states that the alpha motor neurons activates the motor tone, which leads to the spindles providing feedback to the brain. This process is done by the gamma motor neurons, who are in charge of controlling the stimulation of the cerebellum. Also, both the alpha and gamma motor neurons meet at the same effector muscles. Furthermore, when the extrafusal…
