Mars: The Rehydration Of Mars

Submitted By

Pages 6
Mars is generally thought to be a dry lifeless wasteland, however at one point it may have possessed an environment alike Earth's. This theory has provoked scientists to delve deeper; looking for signs of current or past life on Mars. The lack of any vegetation or other visible organisms on mars indicated that the only life that may be found would reside in the dirt of the red planet. Instead of referring to the matter covering the surface of mars as soil it is referred to as dirt; for this matter to be considered soil it would have to be proven to contain organic life. The dirt itself has remained undisturbed for an unknown amount of years longer than mankind could measure without a sample of Mars. If a sample were to be retrieved then it …show more content…
We carefully inserted the sterilized spoon into the N.A.S.A. ziplock bag obtaining approximately 12 gram sample of the dirt. This dirt was then transferred into a small dish where it was mixed with 10ml of distilled water to rehydrate the sample. The rehydration of the sample was intended to mimic the conditions found within the moist Mars craters. We hoped that somehow any bacteria or possibly algae would flow to the lowest part of the dish. From the lowest portion of the dish we used a sterilized unopened cotton swab to obtain a testing sample from the dish. This swab was then inserted into a glass graduated cylinder that had been cleaned using ethanol. The cylinder contained 2 ml of distilled water, we then dispensed that water into a clean petri dish containing agar jelly that contained 5% beef broth to provide the culture nutrients. We then placed that dish in an incubator set at 37* Celsius, which is the same temperature found inside of a human body. We replicated these steps again sterilizing everything to prepare another petri dish, and placed it in the incubator. For the control in our experiment we used no martian dirt; we only poured 2 ml of distilled water into a clean dish. We then inserted a clean swab into the dish, after which we put the swab into the graduated cylinder …show more content…
The dirt from Mars and the surface of the red planet may now be identified as soil due to life being present within it. This alone is a large enough discovery to prompt scientists to take a look deeper into the past of Mars and research different methods of possible terraformation of the planet far in the future. Our experiment not only proved the presence of this bacterial life on Mars, but proved the fact that algae still lives on the red planet. More thorough testing should be performed on the martian dirt to identify the exact types of bacteria and algae within the dish. This type of testing should be performed at a facility equipped with veteran microbiologists as staff, with horribly overpriced scientific devices that only the most prominent laboratories in the world posses. With the supplies and knowledge our group had access to and possessed we conducted our experiment in the best manner we could. Our group's assignment was simply to prove life within the soil, which we

However, vaccination is a critical venture in securing your child against a scope of genuine and possibly deadly diseases. Immunizations are brisk, safe and greatly powerful. Once your child has got vaccinated against an infection, their body can battle it all the more effectively. In the event, that a child is not vaccinated, they will have an expanded danger of getting the illness. B. Immunization is as essential for adults as it is for children, but then numerous adults are not ideally vaccinated. Immunizations emulate the virus so as to anticipate disease by that same virus or bacteria. II. Body A. Vaccine preventable diseases haven't gone away a) Measles is an exceptionally irresistible viral illness that can result in fever, hacking and unique red-cocoa spots on the skin. The shingles antibody is a decent illustration. Shingles are brought on by a reactivation of the chickenpox virus. It can result in a serious and excruciating skin rash. The immunization is suggested for adults 60 and more seasoned (Shah, 1664). b) Measles is brought on by a virus that is exceptionally contagious, can live for up to two hours on surfaces and get transmitted through a tainted individual's hacks or sniffles.

Gatorade Strategy

...in the sports energy drink industry with a significant amount of market share. Currently, Gatorade is the official sports drink of the NFL, NBA, PGA, and many other athletic organizations. As the first mover in the sports energy drink market, Gatorade has set itself apart from rivals like PowerAde and Vitamin Water by creating value for customers by establishing business relationships, conducting scientific research, and product innovation. The Gatorade Company is part of QTG (Quaker, Tropicana, Gatorade) and has been a subdivision of PepsiCo since 1998. When Quaker Oats acquired the company in 1983, it was the largest energy drink company in the world with market share of 97% (Rovell, 2006). The company’s product line focuses on rehydration, recovery, energy, and sports performance. Gatorade is considered an innovative product as it was the first mover in the sports energy drink market. Prior to Gatorade entering this market, water was the only other source for hydration among athletes. This paper will analyze how Gatorade aims to achieve the five elements of strategy by focusing on product, place, and promotion. Gatorade was founded by Dr. Robert Cade and Dr. Dana Shires, two medical professors at the University of Florida. In the 1960s, dehydration became a serious problem. That is, at least twenty-five athletes across the nation were dying every year because they were not properly hydrated (Rovell, 2006). Players who were drinking water as a means of hydration had stomach...

Nike Recommendation Report

...EXECUTIVE SUMMARY NIKE INC. In an effort to become one of the world’s leading designers, marketers, and distributors of athletic footwear, apparel, equipment, and accessories, Nike Inc. started with two visionary men who transformed themselves into one of the top selling brands in the athletic shoe industry. Through taking chances and understanding customers needs, Nike Inc. has established a large market position and strong brand equity. Nike Inc. understood early in its history that aligning its products with top athletes like Tiger Woods, Lance Armstrong and Michael Jordan, would propel the Nike brand to the very top. Nike also fostered endorsements with both individuals and associations like the NFL. Nike also takes into consideration the impact of giving back, having a positive Corporate Social Responsibility and being environmentally conscious. At the same time Nike experienced setbacks due to their dependence on third party manufacturers and having limited control. Nike Better World CSR Campaign targets smaller waste output (carbon footprint) and paying closer attention to the way their products are being manufactured (labor force) helping Nike to get back in good standing with consumers. Because, the market for sporting goods is intensely competitive, it is important for Nike to realize that it is not just the young “hip” generation that is going to keep them on top. The older “Baby Boomers” can help them to succeed too; this generation is known for...

Fear: Do We Control It?

...Fear: Do We Control It, Or Does It Control Us? TLJ Honors Psych Fear: Do We Control It, Or Does It Control Us? Abstract Fear is the mind's way of responding to both physical and emotional danger. It has vast effects on an individual's psychological state, and is directly controlled by the amygdala. Fear is a necessary defense, because without it we would not protect ourselves from legitimate threats. Traumas and bad experiences can trigger emotional fears. Though it seems nowadays, we play into these fears -- fears that are not at all life threatening-- all too often allowing them to become irrational fears. Since the beginning of time there has always been an instilment of fear in our minds, whether the fear was that of eating the 'Forbidden Fruit' , to local legends like Slenderman, and even the bizarre idea of a robotic coup de' etat. The only difference between these fears, is how strongly we let them affect us psychologically. Do we allow our fears to be spoon-fed to us by society and the media? Are we completely irrational when it comes to some of these fears? What is the correlation between our fears of the past and those of the present? Finally, what will the future of mankind hold? All of these factors play a major part in understanding the affects fear can have on society as a whole. Keywords: Fear, Irrational, Media, Past, Present, Future Fear: Do We Control It, Or Does It Control Us? Since the dawn of time...

Ben Kibler TENNIS RECOVERY A Comprehensive Review of the Research A United States Tennis Association Sport Science Committee Project Editors: Mark S. Kovacs, PhD Todd S. Ellenbecker, DPT W. Ben Kibler, MD Introduction In the last two decades, physical training and competitive opportunities have increased dramatically in junior, collegiate and professional tennis. This arose due to a multitude of factors, but much of it has stemmed from an increase in knowledge and understanding of scientifically based training programs focused on improving performance. As this focus on performance has increased, the area of recovery has received relatively limited focus. Recovery is a multi-faceted paradigm focusing on recovery from training—session to session, day to day and week to week. Recovery is also vitally important during training as well as in competition between matches and between days during multi-day tournaments. As more information is needed in the area of tennis specific recovery, the Sport Science Committee of the United States Tennis Association (USTA) sponsored an extensive evidence-based...

The Assessment and Management of Acute Pyelonephritis in Pregnancy

...The assessment and management of acute Pyelonephritis in pregnancy ------------------------------------------------- Urinary tract infection (UTI) incorporates a range of conditions including acute pyelonephritis or kidney infection. It is almost invariably caused by bacteria (Brown et al 2005, Le 2004). The incidence of this disease in pregnancy has decreased in recent years (Dawkins et al 2012), possibly due to improved antenatal care. However, it remains one of the most common complications in pregnancy (Hill et al 2005) affecting 1-2% of pregnant women (Dawkins et al 2012, Hill et al 2005, McCormick 2008). Acute Pylonephritis is the most serious urinary tract infection in pregnancy (Le 2004, McCormick et al 2008) and successful treatment usually requires hospital admission (Jolly and Wing 2010). It is most often seen in nullparous and younger women and there appears to be a link with lower socioeconomic status, diabetes and sickle cell disease, although not with ethnicity (Hill et al 2005, Jolley et al 2012). It is more common in the 2nd and 3rd trimester (Archabald et al 2009, Hazhir 2007, Hill et al 2005) as the presence of urinary pathogens seems to increase as pregnancy advances (Hill et al 2005). There does appear to be an association between repeated urinary tract infections and sexual activity (Bernard et al 2011, Pfau and Sacks 1992). If not effectively treated, acute pyelonephritis may have serious consequences for both the mother and fetus. Urinary...

Deshydratation

...------------------------------------------------- INTRODUCTION Aujourd'hui, des enfants meurent encore de déshydratation aiguë. Nous ne pouvons donc banaliser cette question classique de la pédiatrie d'urgence, d'autant plus qu'il s'agit d'une pathologie fréquente. Il est possible actuellement de proposer des protocoles simples basés sur une physiopathologie claire qui permettent de faire face à la majorité des situations. Quatre points sont essentiels à retenir : · Un enfant est essentiellement constitué d'eau. · Celle-ci est principalement située dans le secteur extra cellulaire. · Son renouvellement est très rapide. · Le nourrisson dépend entièrementd'autrui pour satisfaire ses besoins hydriques. Ces principes permettent de comprendre la grandefragilité du nourrisson à tout déséquilibre de sabalance hydrique. Ils permettent également de comprendre lagravité potentielle des déshydratations et leur retentissementrapide sur le secteur extra cellulaire et notamment sur la volémie. Labaisse de la volémie peut conduire au choc hypovolémique et parconséquent à une défaillance multi viscérale quifait toute la gravité des déshydratations. Laparticularité de ces chocs est qu'ils peuvent survenir trèsbrutalement chez un enfant qui donnait l'illusion d'avoir unedéshydratation modérée quelques heures auparavant. Au cours d'une diarrhée, l'évaluation del'état d'hydratation de l'enfant est primordiale, notammentl'appréciation du pourcentage de la perte de poids(moins...

Research Paper

...When it comes to understanding animals and the diseases they have, contract, and carry there is no limits. From dogs and cats to livestock and exotics it is necessary to learn and understand diseases from metabolic to degenerative or idiopathic, Neoplastic diseases and Toxic poisonings, Congenital and Genetic diseases to Immune related diseases, and Infectious and Contagious diseases to Parasitic Infections. There is a world that one can get lost in when it comes to learning about theses things. Some diseases have been around for years while others are still being studied with new ones occurring today in the modern world. Along with these diseases it is important to study and understand what causes them, what signs to look for, what species to look for them in, how to treat them, and how to prevent them from happening, IF you can even prevent them. Some diseases and conditions have vaccines to help with prevention and some do not, while some diseases are zoonotic meaning that they can be transmitted from animal to human. While there are hundreds upon hundreds of diseases to be looked at, the ten researched below are the ones once prevalent among the veterinary technicians job in the clinic; Hip Dysplasia and Ethylene Glycol poisoning in dogs, Hyperthyroidism and Rabies in cats, Strangles and Equine Recurrent Uveitits in Horses, Cryptosporidium and Fasciola Hepatica in Ruminants and Swine, Idiopathic Epilepsy in Aviaries, and Lymphoma in Ferrets.
