Mars Exploration For centuries mankind has been fascinated by the night sky. Countless numbers of scientists have dedicated their lives to learning and exploring our solar system. The National Aeronautics and Space Administration has consistently lead the USA and the world in space experimentation and planned missions. One area they have actively pursued is the study of Mars. NASA has researched planet Mars for over decades and recently released a detailed plan containing their strategy for a…

CHAPTER 2 LITERATURE REVIEW 2.1 Effect of Binder and Plasticizers on the Gel Viscosity, Membrane Morphology and Pore Size According to M.R. Othman [7] the result of addition of PVA in Boehmite sol during peptization on the viscosity, coating time, pore size and BET surface area is presented in Table I,II,III, and IV. PVA was prepared by dissolving 2, 4, 6 and 8g of PVA powder into 100mL de-ionized distilled water. PVA with different concentration in the sol give a of characteristics viscosity…

France was the home of the Impressionist movement, providing a vast array of landscapes, people and lifestyles as inspiration. The famed impressionists used the bustling nightlife of Montmartre, studious industrial areas, and open landscapes of rural France to influence their works. Specifically, Maximilien Luce used the rural province of Brittany in Western France to inspire his work Camaret, Moonlight and Fishing Boats painted in 1894. Brittany was used as inspiration by many impressionists…

Culture is what, how, and why we do the things we do. Culture is practices we do in our daily lives. It is the meanings that we create and materialities that mold our interactions. Culture is realized through our interactions and is self-governed, performed, and enacted. There are 6 building blocks that form what we know today as culture: 1. Norms, Values, and Beliefs 2. Frames and Symbolic Boundaries 3. Cultural Repertoires, Scripts, and Ideas/Knowledge 4. Discourses and Narratives 5.…

ISE SUMMER PROJECT 2015 Probability, randomness, and chance should be central in any STEM pedagogical model. The concepts of randomness and chance play a very significant role in the essence of all sciences, and especially in the empirical sciences. Randomness is a critical component of biological modeling at many levels in a wide range of systems. The fundamental axioms of the quantum paradigm in physics are, by definition, essentially stochastic. Economics uses the randomness in human thought…

The carbon supported PtFeS catalysts were prepared by a modified polyol method. In brief, 0.3 g carbon (Ketjen-black heat-treated at 2250 °C, SE = 160 m2 g-1) was dispersed in 135 g ethylene glycol. 5.993 g of 8 wt% H2PtCl6 (Umicore; Pt content, 39.8 wt%), 1.874 g of 8 wt% FeCl3. 6H2O (Sigma-Aldrich), and 0.352 g of 8 wt% (NH2)2SC (Sigma-Aldrich) previously mixed in ethylene glycol were added to the dispersion. The pH of the stirred reaction mixture was adjusted to ∼11 using 1 M NaOH dissolved…

Throughout many centuries, it has always been important to know how and why crimes have been committed. Criminal Investigators have participated in solving countless of cases in order to prevent future crimes. Many victims and those accused, which are known to be innocent, have been assisted to receive justice due to the help from the system. This job profession is just as important as any others in the federal justice system. Forensics investigation is a standard scientific application to…

The year of 1953 is surprisingly considered an important year in history, but it’s never too late to reminisce about the extraordinary occurrences of this time. The popularity of 1953 flourished solely from the discoveries in the field of science and medicine. Two wise, intellectual scientists unveiled the secretive and mysterious structure which is known for creating diversity in humans. Just one month later, the origin of life was potentially discovered in a simple laboratory in Chicago,…

Introduction: The ability of substances within a solution to absorb light is a wonderful phenomenon as it aids in processes such as determining the concentration of proteins. The way that a solution absorbs light is due to the photoelectric effect. The way the photoelectric effect works is that when light comes in contact with the sample, the photons of light will react with its electrons. As the light travels through the solution, "a photon of light may interact with an electron ... [where]…

impacted the world of optics greatly. One of these tools was the spectrometer. This instrument allows each part of the spectrum of light to be observed by passing natural light through a slit then through a lens, and thus the light becomes spread by diffraction. With this…
