...Week 3 Lab Research Report 1 Ciera M. Jimerson Professor Alisha A. Etheredge SCI-110 October 27, 2013 Once it was impossible to understand the composition of the smallest basic cells, until the invention of microscopes. Even with the tools that exist it is not always possible to safely do in a field that deals with atoms, particles, radiation, and unstable compounds. The technology in the area of physical science makes it very important on how much is learned and studied in the fields of astronomy, chemistry, physics and even earth sciences. There have been many advances that allow for direct measurements in the field of physics, there are many obstacles and challenges to making direct observations in many circumstances. Physics is the study of energy, matter and the interaction between the two, which are impossible to observe with the naked eye. One common thing the field studies is energy creation to non-particles, all of the most recent discoveries in subatomic particles and the origins of the universe have all creative methods to study things that are extremely tiny. This would be the first major challenge to making direct measurements in physics. To avoid this problem, physicist usually studies these particles indirectly through things like associated radiation, energy, or the displacement of other atoms and/or compounds. Every measurement made on atoms or subatomic particles has caused indirect measurements (Kross). There are certain measurement tools whose...

...English scientist Rosalind Franklin is best known for her part in the disclosure of the structure of DNA, and for her spearheading utilization of X-beam diffraction. Conceived in 1920 in London, Britain, Rosalind Franklin earned a Ph.D. in physical science from Cambridge College. She learned crystallography and X-beam diffraction, strategies that she connected to DNA filaments. One of her photos gave enter bits of knowledge into DNA structure. Different researchers utilized it as proof to help their DNA display and assumed praise for the revelation. Franklin passed on of ovarian tumor in 1958, at age 37. English physicist Rosalind Elsie Franklin was naturally introduced to a well-to-do and compelling Jewish family on July 25, 1920, in Notting Slope, London, Britain. She showed remarkable knowledge from early youth, knowing from the age of 15 that she needed to be a...

...Science Science is the study of natural physical things. The word science comes from the Latin word “Scientia,” meaning knowledge. Science is totally based on observation and experiment. We are living in the age of science. We are surrounded with the gifts of science. Now we are so accustomed with it that we cannot pass a single day without it. Electricity, light, fan, computer, fax, telephone, mobile phone, television, aero plane, vehicles, x-ray, radio, medicines, medical equipments are some of the innumerable gifts of science. In every sector of our life science and technology have some contributions. The purpose of science is to produce useful models of reality. It has made our life easy and comfortable. Without proper implementation of science and technology, no nation could grow. It has helped us use the forces of nature for the welfare of human beings. At the same time we can combat against natural disasters with the help of it. That is why we are indebted to it. But some people use these gifts against mankind. They are using science and technology to make arms. Science is leading to side effects like global warming, pollution, chemical weapons etc. Unfortunately, science cannot prevent these side effects. We must stop it and use it to alleviate pains and sufferings and establish peace and happiness in the society. We as citizens of the nation and who hold equal responsibility for the growth should equip our youth with all possible facilities for their research thirst...

...rigour will fix the problem of uninteresting research publications and their controversy against pedantic literatureReviews who only agree with incremental, gap-spotting research. However, they contested the belief of Alvesson and Sandberg that rigour in research always leads to baleful outcomes; in the opposite ’Rigour’ is used to challenge assumptions. First argument: most interesting research comes from challenging consensus and overthrowing assumptions by introducing new ideas that contain more valid insights about organizations. * ‘Rigour’ can be one way to produce such valid insights. Second argument :’Rigour’ ensure the measure of variables X and Y, the affects of X on Y through variable Z, explain the causal connection between them, stating the boundary condition under which X affects Y and outside of which X does not affect Y. * ‘Rigour’ is essentially the...

...restoring suffrage in Southern states. “The truth is that no bill insuring civil rights to any person can be enforced so long as there are loopholes available in our political systems loopholes that are the progeny of the very basis of that system, federalism”.(Johnpoll,1964) Civil rights are guaranteed by law but took many years to achieve. For example even after the Civil War, African Americans were treated badly. They got the worst jobs and were paid poorly. Blacks and white were segregated. In other words, they were kept separate in public places including at theaters, restrooms, schools and in transportation. In the 1950's and 1960's Dr. Martin Luther King Jr. became known as the leader for the nonviolent civil rights movement. Malcolm X quickly became very prominent in the movement with his own group of followers. Noted legislative achievements during this phase of the Civil Rights Movement were passage of Civil Rights Act of 1964, that banned discrimination based on "race, color, religion, or national origin" in employment practices and public accommodations (n.a.2009). The Voting Rights Act of 1965 that restored and protected voting rights (n.a.2009). The Immigration and Nationality Services Act of 1965 (n.d), that dramatically opened entry to the U.S. to immigrants other than traditional European groups; and the Fair Housing Act of 1968(n.a 1981), that banned discrimination in the sale or rental of housing.

...Destructive Test (NDT) X-Ray Advantages of X-Ray X-rays are invisible electromagnetic energy, which is used as a way to get or make images of internal tissues, bones and organs of our body. It is by this process that an expert determines bones of a patient are intact or broken after an accident. Likewise, you can find internal injuries to organs. In addition, X-rays are used to find out whether or not a person has a cancerous tumour. With the increasing technological advances, the dose of the radiation exposure to patients has decreased (www.chem.ucla.edu). X-rays are a form of ionizing radiation which can pass through materials. The X-ray technology is an invaluable tool for medicine, industry, science and security. For example, it can be used to observe the fractured bones and swallowed objects, to monitor the blood flow of patients and to check for cavities. In addition, X-rays can be used to diagnose cancer, kill bacteria in food, detect flaws in machinery or products, analyze the structure of crystals or distant stars and inspect baggage at airports (www.chem.ucla.edu). Now there were more modern medical devices, which process image digitally. This technique automatically selects the parameters of the human organs to be examined (www.chem.ucla.edu). Disadvantages of X-Ray The discovery and immediate use of X-rays and radioactive elements, in the late 19th century and early 20th century brought benefits to science and medicine, but also caused...

...5) An x-ray diffraction analysis of a crystal is made with a molybdenum target (λ = 0.711A°). If one of the interplanar spacings is 1.82A°, what is the angle of diffraction for this particular set of planes (assuming first order diffraction). n=1 d=1.82A° λ=0.711A° θ= ? nλ=2dhklsinθ θ=sin-11x0.7112x1.82 θ=11.3° 6) Sodium metal crystallizes in a body-centered cubic arrangement where the length of one edge of the unit cell is 4.24A. What is the closest distance between centres of adjacent sodium atoms? d=4.24A°x3 4 d=1.84A° 7) A crime investigator in a forensic sciences laboratory wishes to identify the makeup of some material evidence. He suspects that the material is actually a mixture of two pure substances. Outline a method by which you think these two substances might be identified. A great way for the crime investigator to identify the makeup of the material evidence would be to use x-ray diffraction. Every crystalline material in the world has its own diffraction pattern unique to one another, which would cause for the best solution to the problem encountered by the crime investigator. Once the material is illuminated with monochromatic X-rays, the atomic lattice of the sample causes the x-ray beam to be diffracted to specific angles. Once completed the use of Bragg’s law allows us to identify the atomic spacing of the mystery material and from there we can compare the unknown material to a list of known materials in order to discover the makeup...

...Radiation Exposure Karen Glave University of Texas Health Science Center, Houston, Texas Author Note Karen Glave, ARRT, RT (R) is the Lead Radiologic Technologist at the UT Physicians, Cinco Ranch Health Center in Katy, Texas. A multi-specialty, community based clinic that is a division of the University of Texas Health Science Center in Houston, Texas. Correspondence concerning this report should be addressed to Karen Glave, RT, Department of Radiology, UT Cinco Ranch Health Center, 23923 Cinco Ranch Blvd, Katy, Texas 77494. E-mail: karen.glave@uth.tmc.edu Abstract During my 20 years of imaging in the radiology field, I have been questioned by patients about the dangers of radiation exposure daily. I often state that unlike other medical trials we are unable to intentionally test the long term effects of these procedures. To take a group of people and irradiate them, follow them throughout their lives. That type of study would be never-ending and difficult to follow. Our history lessons teach about the bombs dropped on Hiroshima and Nagasaki, Japan in 1945 and the 1986 Chernobyl Nuclear Power Plant explosion in Ukraine. However those events do not expose human beings to the same ionizing radiation that is used in the medical x-rays of today. I would like to put these risks into perspective. That the benefit of the information we receive from a test far outweighs the risk to the patient. My ultimate goal is to arm the patient with enough information to make...

...Transmitted Disorders Introduction Genetics originated in the mid-19th century when Gregor Mendel discovered over a ten year period of experimenting with pea plants that certain traits are inherited. His discoveries provided the foundation for the science of genetics. Mendel's findings continue to spur the work and hopes of scientists to uncover the mystery behind how our genes work and what they can reveal to us about the possibility of having certain diseases and conditions. The scientific field of genetics can help families affected by genetic disorders to have a better understanding about heredity, what causes various genetic disorders to occur, and what possible prevention strategies can be used to decrease the incidence of genetic disorders (Pitman, 2002). What is Heredity? Why do children look like their parents? Why do brothers and sisters resemble each other? This is because we “inherent” traits from our parents. The passing of traits from parents to child is the basis of heredity. Traits are physical characteristics. Eye color, nose shape, and many other physical features are some of the traits that are inherited from parents (Kristine & Stewart, 2007). What is genetics? Genetics is the science that studies the mechanics of heredity, or the means by which traits are passed from parents to offspring. Through genetics a number of specific disorders have been identified as being genetically caused (ibid, 2007). Dominant Inheritance Dominant...

...Getting an Inside Look: Given Imaging’s Camera Pill The factors which makes Iddan, an engineer with no medical background, to pioneer the development of wireless endoscopy are he as an electo-optical engineer and was working on developing the “eye” of guided missile to its target. His friend at boston gave him information about technology used for viewing the interior lining of the digestive system which had lots of limitations, specially with viewing the small intestine. This small intestine causes serious disorders and only in United States approximately 19 million people suffer from disorders. Existing technology like X-ray and endo-scopes were unable to identify or investigate about small intestine. So the only option left was surgery and which was very crucial if the physician does not know which part of the small intestine is affected. So his friend encourages him to come up with better technology. Due to technology revolution after decade small video cameras which uses image sensors like CCDS (Charge coupled devices) has been developed. With his knowledge from developing the eye of guided missile he tried to make small missile like device which could travel through the intestine without a life line leading to the outside of the body and transmit images wirelessly to a receiver outside of the body. He has also done small experiment on chicken with his developed camera and as he succeeds he got more encouragement but he found battery of that camera get exhausted in...
