Crew Personalities on the Mission to Mars Essay - 3505 Words

Crew Personalities on the Mission to Mars The importance of psychology in space flight has been well documented and addressed by NASA and other organizations conducting space exploration. A manned mission to Mars has no precedent. The Apollo missions to the moon are the most similar attempts at space exploration, but these were significantly shorter in duration, did not have the difficulties in communicating with earth that the huge distance between Earth and Mars poses, and the experiments performed were not nearly as complex as those that would be done on Mars (ie. tests for life, carbonates, and underground ice). These new variables leave us with unknown psychological and physiological threats that no one can truly predict†¦show more content†¦But his therapist was back in Nice, fifteen timeslipped minutes away at best, and Michel talked to him but he couldn’t help†¦.While Michel was a doctor in a hospice in a prison in hell; and the doctor was sick. (Robinson 215) His personality influences the onset of depression he experiences, as the novel explains â€Å"he [Michel] hadn’t been able to adapt. People were different in that regard, it was a matter of temperament.† (Robinson 215) The difference between him and many of the other members of the crew is that he is a typical introvert; he keeps to himself and avoids involvement in many of the issues of debate between others. Analysis of extraverts and introverts shows that introverts’ â€Å"negative expectations about ongoing or impending social interaction lead to either social avoidance or feelings of distress and discomfort or both.† (Morris 89) It is natural then, that Michel is not inclined to share his difficulties with any other members of the crew, and struggles to feel like a fully accepted member of their society. His ability to function safely and in relative comfort while on the ship and in Underhill is therefore quite unsatisfactory. Study of interpe rsonal compatibility has yielded conclusions that express a â€Å"need to establish satisfying (personally rewarding) social relationships with others† (Mabry 39) and a â€Å"need to maintain satisfying power relations with others, by either dominating (having power) over others, orShow MoreRelatedThe Accomplishment Of Space Travel1923 Words   |  8 Pagesalso known to â€Å"cause the ‘moon-face’ appearance typical in pictures of astronauts† (Akiyama 22).

Cancer The Most Important Causes And Complications Of...

Breast cancer is the most prevalent cancer identified in women, and in spite of substantial developments in cancer treatment, it is still the second most important cause of cancer-related deaths. In general, up to 25% of breast cancer patients overexpress HER2 gene. Recently, the mAbs that identify antigens on cancer cells are being used for the targeted therapy of cancer. The antibodies can be used alone or as conjugates for the transport of radioisotopes, toxins, or drugs. Immunotoxins are manufactured by the connection of an antibody to a toxin produced by a plant or a bacteria. In this study, Pseudomonas endotoxin A (PE) and Shiga toxin (STX) and Fv fragments of the anti-ErbB2 mAb herceptin was used to create a single-chain variable†¦show more content†¦Overexpression of the ErbB2 gene has beenfound in many human cancers including lung, breast, ovary, and stomach malignancies(2). About 25% of breast cancer patients overexpress HER2 gene(3, 4). Amplification of HER2 gene has been directly related to the malignant alteration of cancer cells, and therefore, makes it a great target for immunotoxin therapy. This finding has led to the development and approval of the first HER2-targeted therapy(4). Altogether, it is essential to target tumor cells using considerably strong lethal agent as cancer therapeutics.. On one hand, this approach makes it possible to use more potent drugs to treat cancer on the other hand, it may decrease systematic toxicity(5). Antibody-based therapeutics are of high significance in cancer therapy and mAbs that identify antigens on cancer cells are being recruited for the targeted cancer therapy (6). In HER2-positive breast cancer patients, numerous HER2-targeted therapeutics have been effectively designed and approved for the cancer treatment. Trastuzumab (Herceptin), the first accessible HER2 targeted therapy, is a humanized murine IgG monoclonal antibody that binds to the HER2. Antitumor activity of trastuzumab has not been discovered entirely, but, it is assumed to result in antibody dependent cell mediated cytotoxicity, declined intracellular signal transduction, decreased DNA repair and anti angiogenic effects(7).

Properties of Water Essay Example For Students

Properties of Water Essay Properties of WaterWater is essential for life as we know it on earth. It is used by plantsand animals for basic biological processes which would be impossible without theuse of water. The origin of all life can be traced back to the water in theEarths precambrien seas. Water is also the universal solvent. It reacts withmore elements and compounds than any other substance known to man. Water is a polar molecule made up of on atom of hydrogen and two atoms ofoxygen. It is attracted to itself by hydrogen bonds. Hydrogen bonds are weakerthan covalent bonds, but collectively these bonds hold water together and giveit its cohesiveness. These bonds are also very important to waters ability toabsorb heat, as without hydrogen bonds water would have a boiling point of -80degrees C and a freezing point of -100 degrees C. In reality, however, water has a boiling point of 100 degrees C and afreezing point of 0 degrees C. The amount of energy needed to raise thetemperature of one gram of water by one Celsius degree is called a Calorie. OneCalorie is about twice as much energy as you need to warm one gram of most otherfluids by the same amount. This makes water much better for regulating thetemperatures of animals and the environment. Water also has a very high heat of vaporization. Converting one gram ofcold water into ice requires 80 Calories of energy. Converting the same amountof very hot water into steam requires 540. The high amounts of energy requiredto change water from its liquid state make water tend to stay a fluid.Theprocess of freezing water involves slowing down the activity of the watermolecules until they contract and enter into a solid state. Once the ice iscooled down to 4 degrees or less, the hydrogen bonds no longer contract, butthey become rigid and open, and the ice becomes less dense. Because the ice hasbecome less dense, it floats on liquid water. Water freezes from the top down. Once the top freezes, it acts as an insulator, so that the water beneath ittakes a very long time to cool off enough that it freezes. This also traps justenough warmth to keep marine animals alive during the winter. The process of turning water into steam is a different story. Because itrequires the breaking of waters hydrogen bonds, this process takes far moreenergy than it does to turn water into ice. The extra energy that is used inconverting water into steam helps keep the overall temperature from getting toohot. In this manner water regulates the temperature of both animals when theysweat, and the earth through evaporation. Water affects the earths ecosystems in very important ways as well. Whenwater in the earths saltwater bodies evaporates into the air. This water vaporthen cools off, becomes liquid again, and then falls as rain or snow. The saltis left behind, and the resulting precipitation helps replenish the water inlakes, streams, rivers, and the groundwater supply. However, all of this watereventually flows down to the level of the oceans, and the cycle begins again. Because of this cyclical pattern, water is consided to be a renewable resource. However, some chemical impurities can remain with the water, even through theprocess of evaporation. These remain in the water and cause problems until theyare either filtered out by natural or artificial processes, or until they arediluted enough that they are no longer a problem. Of all the water on the earth,only three percent is fresh. Of that three percent, only 1/3 is considered safefor consumption. .ue6284338c29ba56753fe5468e6d81953 , .ue6284338c29ba56753fe5468e6d81953 .postImageUrl , .ue6284338c29ba56753fe5468e6d81953 .centered-text-area { min-height: 80px; position: relative; } .ue6284338c29ba56753fe5468e6d81953 , .ue6284338c29ba56753fe5468e6d81953:hover , .ue6284338c29ba56753fe5468e6d81953:visited , .ue6284338c29ba56753fe5468e6d81953:active { border:0!important; } .ue6284338c29ba56753fe5468e6d81953 .clearfix:after { content: ""; display: table; clear: both; } .ue6284338c29ba56753fe5468e6d81953 { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .ue6284338c29ba56753fe5468e6d81953:active , .ue6284338c29ba56753fe5468e6d81953:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .ue6284338c29ba56753fe5468e6d81953 .centered-text-area { width: 100%; position: relative ; } .ue6284338c29ba56753fe5468e6d81953 .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .ue6284338c29ba56753fe5468e6d81953 .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .ue6284338c29ba56753fe5468e6d81953 .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .ue6284338c29ba56753fe5468e6d81953:hover .ctaButton { background-color: #34495E!important; } .ue6284338c29ba56753fe5468e6d81953 .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .ue6284338c29ba56753fe5468e6d81953 .ue6284338c29ba56753fe5468e6d81953-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .ue6284338c29ba56753fe5468e6d81953:after { content: ""; display: block; clear: both; } READ: Type 2 Diabetes EssayThe properties of water give it the ability to react with differentelements and molecules in very interesting ways. Waters properties allow it tobe the focal point of many cellular functions, primarily because of its reactiveabilities. Ionization is one example of these reactions. This occurs when a watermolecule in a hydrogen bond with another one loses an atom of hydrogen. Theremaining particle is a hydroxl ion. Micromolecules with different charges thanwater can cause ionization to happen as well. During the process of ionizationwater realeases an eaqual number of hydrogen (H+) and hydroxyl (OH-). Thisdissociation process involves only a few water molecules at once. The actualnumber is about 10-7 moles/liter). Acids L. acidus, sour are molecules that release the hydrogen ions inthe dissociation process. Strong acids, such as hydrochloric, dissociate almostentirely in water. Bases are molecules that take up these extra hydrogen ions. Water passes through pores easily. Cells take advantage of this byhaving channels tiny holes in the cell membrane. These are exactly theright size that water can get through them, while larger particles are heldinside. Osmosis Gk. Osmo, pushing is defined by the Sylvia Mader textbook as the diffusion of water across a differentially permeable membrane. Thisprocess is caused by a fluid attempting to seek equilibrium by going from a highpressure situation into a lower pressure one. This pressure that causes thisoperation is known as osmotic pressure. Another interesting state that water can be in is that of an isotonicsolution. These are solutions which neither water is neither gained nor lost,and the pressure is equal on both sides of the cell membrane. When thispressure is not equal, the degree of the inequality is defined as tonicity. When the pressure is very unequal, so that the pressure causes water toflow inward, it is known as a hypotonic solution hypo, less than. The lessthan prefix refers to a solution with a lower percentage of solute, and whichcontains more water than the cell. The cell then swells, possibly even to thepoint where the cell will burst. These exploded cells are referred to as lysis. The pressure that caused them to pop in the first place is referred to turgor L. turg, swell pressure. The opposite state is referred to as a hypertonic solution hyper, morethan. The more than prefix in this word refers to a solution with a higherlevel of solute, and the cell contains more water than the outside solution. Therefore, a cell in a hypertonic solution tends to shrivel up like a grapefruitin the sun. Animals regulate the amount of water in their bodies in very individualways, each suited for the environment in which they each live. Sharks and fishare able to live in an environment nearly saturated by salt by having a sort aimmunity to it. Some sharks survive by making their blood as toxic as thesurrounding water. Certain seaside animals as well have developed ways to keep the salt intheir water from dehydrating them. Some kinds of birds and reptiles have a sortof nasal salt gland which allows them to excrete the large amounts of salt thatthey take in when they drink. Some mammals as well can live in highly salineenvironments by making their urine stronger, and having very dry fecal material. .

Research Paper Tap water vs. Saline free essay sample

Proper cleansing is perhaps the key component for acute and chronic wound management. Cleansing methods differ among health care providers and institutions, and many times is based on an individual’s experience and preference. Many cleansing solutions exist today. In this research, the author focused on the use of tap water versus sterile cleansing solutions such as Normal Saline and sterile water. Many cleansing solutions are safe and have been proven to provide effective results, whereas others may damage the tissue, destroy cells, increase infection rates and delay the healing process. Normal saline is regarded as the most appropriate and preferred cleansing solution by health care providers because it is nontoxic, isotonic solution that does not damage healing tissue. However, tap water is most commonly used among people, especially those that are discharged home and ordered to continue wound care at home. Tap water is cost effective and easily available, therefore of interest as a cleaning solution. We will write a custom essay sample on Research Paper Tap water vs. Saline or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page Tap water showed to be as effective as any sterile solution in acute and chronic wound care. As an emergency and trauma nurse, I am often involved in the care of acute traumatic wounds and chronic wounds as well. Many practitioners prefer the use of a sterile isotonic solution, such as Normal saline while irrigating and cleansing wounds. After many years working with traumatic and chronic wounds, I have wonder if there is significant evidence to argue the following PICO question: When caring for patients in need of wound care, does sterile isotonic saline reduce infection rate and shorten healing time when compared to tap water? The following research will give us a better understanding on the use of sterile water versus tap water in the treatment of acute and chronic wounds from the emergency room perspective. Patients with acute or chronic wounds that present to the ER for wound care. I- Using tap water for wound care. C- Using a sterile solution, such as Normal Saline (an isotonic solution) for wound care. O- Infection rate and differences in healing time. When caring for patients in need of wound care, does sterile isotonic saline reduce infection rate and shorten healing time when compared to tap water? Article #1. Water for Wound Care. A level 2 research study. Reference Fernandez, R, Griffiths, R, Ussia, C. (2008). Water for wound cleansing. Cochrane Database of Systematic Reviews. Issue 1. Art. No:CD003861. DOI: 10. 1002/14651858. CD003861. pub2. Normal saline has been the favored isotonic solution used for acute and chronic wound care, since it does not interfere with the normal healing process. However, tap water is commonly used for cleansing wounds because it is easily accessible, efficient and cost effective. For this study, a randomized and quasi-randomized controlled trial was identified by electronic searches of Cochrane Wounds Group Specialized Register and the Cochrane Central Register of Controlled Trials. Eleven trials were included in this review. Seven trials compared rates of infection and healing in wounds cleansed with water and normal saline. Three trials compared cleansing with no cleansing and one trial compared procaine spirit with water. There were no standard criteria for assessing wound infection across the trials. The major comparisons were water with normal saline, and tap water with no cleansing. For chronic wounds, the relative risk of developing an infection when cleansed with tap water compared with normal saline was . Tap water was more effective than saline in reducing the infection rate in adults with acute wounds (0. 63). The use of tap water to cleanse acute wounds in children was not associated with a statistically significant difference in infection when compared to saline (1. 07 from 0. 43-2. 64). No statistically significant differences in infection rates were seen when wounds were cleansed with tap water or not cleansed at all. When caring for patients in need of wound care, does sterile isotonic saline reduce infection rate and shorten healing time when compared to tap water? Article #2 Water is Safe and Effective. A level 3 research study. Reference Weiss, E. (2012). Water is a safe and effective alternative to sterile normal saline for wound irrigation prior to suturing: a prospective, double-blind, randomized, and controlled clinical trial. British Medical Journal. http://bmjopen. bmj. com/content/3/1/e001504. full DOI: 10. 1136/bmjopen-2012-001504. This was a single centre, prospective, randomized, double-blind controlled trial. The wound solution type was computer randomized and allocation was done on a sequential basis. The patients were older than 1 year of age, who presented to the emergency room with a soft tissue laceration requiring repair. The primary outcome measure was the difference in wound infection rates between the two randomized groups. During the 18 month study period, 663 consecutive patients were enrolled, but only 631 were used for the study. From the 631, 318 were randomized into the Tap Water (TW) group and 313 into the Sterile Saline (SS). There were a total of 20 infections (6. 4%) in the SS group compared to 11 infections (3. 5%) in the TW group. Indicating that there is no difference in infection rate of wounds irrigated with either TW or SS solution, with clinical trends towards fewer wound infections in the TW group, making it easy to conclude that tap water is a safe and cost effective alternative to sterile saline for wound irrigation. When caring for patients in need of wound care, does sterile isotonic saline reduce infection rate and shorten healing time when compared to tap water? Article #3. Cleansing chronic wounds with tap water or saline: a review. A level 4 systematic reviews research. Reference Ljubic, A. (2013). Cleansing chronic wounds with tap water or saline: a review. Journal Of Community Nursing. 27(1), 19-21. Some practitioners advocate that cleansing with tap water is better than with saline for healing and has economic benefits; others say there is no difference in the infection rates or healing with either solution. A literature search was undertaken of the electronic databases for relevant systematic reviews, randomized control trials (RCT) and other evidence based literature using the key words chronic wound, wound cleansing, tap water,  saline, infection. No evidence suggesting the use of tap water instead of saline was inappropriate was found. Four studies of 14 RCTs comparing infection rates in wound cleansing with tap water and normal saline in adults and children were identified. The studies evaluated patients in hospitals emergency departments. The trial was a comparison of the effects of tap water and normal saline on the healing and infection rates of acute and chronic wounds. The researchers concluded that there was no significant difference between the infection and healing rates in wound cleansing with normal saline and tap water, and that tap water appears to be a safe alternative. The limitations of this review is that sparse evidence is available to support that the practice of using tap water is a viable option for wound cleaning. Much of the evidence on wound cleansing appears to be based on expert opinion rather than scientific studies, and published studies are not always of good quality. Summary Despite a significance progress in technology for wound care during the last decades, little attention has been directed to wound cleansing. Most providers tend to practice according to experience rather than to evidence based practice when it comes to this subject. Even though there has not been a lot of research done in this area, a few research studies suggest that there’s no significant difference in the patient outcomes when using tap water instead of normal saline, whether is used to cleanse an acute or chronic wound. There is no difference in the infection rate of wounds irrigated with either tap water or saline solution, with a clinical trend towards fewer wound infections in the tap water group, making it a safe and cost-effective alternative to saline solution for wound irrigation. However, there’s not enough evidence to suggest that cleansing wounds per se increases healing or reduces infection either. Some recommendations for this practice have been made: is water is used; it should be at body temperature as it can take 40 minutes for a wound to return to normal temperature after cooling. Nurses must be able to identify the most appropriate solution to use. However, the decision to use tap water for cleansing wounds should take into consideration the quality of tap water, comorbidities that compromise immune function of the patient, and the extent and nature of the wound. But it is safe to say that, in absence of portable water, boiled and cooled water as well as distilled water can be used as wound cleansing agents. Appropriate wound cleansing will continue to be a debate within practitioners until more research is available. The review by Fernandez, â€Å"Water for wound cleansing† (2008), provides some clarity about the comparative benefits of these cleansing solutions in wound care. In order to implement this study in the area I practice, I would implement an experimental study, using a random amount of emergency room patients with acute and chronic wounds. I wound implement the random use of tap water for some as well as normal saline for others and keep track of their wound healing process. I would make sure the candidates are aware of the trial and document my findings after executing a random selection of a large sample. I would focuse on healing time for both, saline and tap water participants, as well as for any infection or complications. The results would be shared with the staff during a staff meeting or in-service in order to apply evidence based findings to our practice. In conclusion: patients with acute or chronic wounds, wound cleansing with tap water does not differ from no cleansing or wound cleansing with sterile normal saline for rates of healing and infection.

Getting Beyond the Basics of the Spanish Future Tense

Getting Beyond the Basics of the Spanish Future Tense If you think that the future tense in Spanish is used to talk about events that will happen in the future, youre only partly right. For the Spanish future tense also has two other uses, one of which corresponds to an English usage and one that does not. And if you think that the only way of talking about the future in Spanish is to use the future tense, youd be mistaken. Spanish Future Tense as Emphatic Command If you grew up not liking vegetables, you may remember having a stern parent saying something like You will eat the carrots with a strong emphasis on the will. In such a sentence, the English future tense is being used not merely to say what will happen, but also to insist that it does. The same can be done in Spanish. Depending on the context and intonation, a sentence such as Comers las zanahorias can be either a prediction or a strong command.  ¡Te dormirs a las 10! (You will go to sleep at 10!) ¡Saldrn si causan problems! (You will leave if you cause problems!) ¡Esturiars toda la noche! (You will study all night!) Unlike with English, this type of reference to the future can be made in Spanish only with the simple future tense. Spanish does not use the progressive tenses (such as estars estudiendo for you will be studying) for this purpose. Spanish Future Tense for Indicating Probability More common is to use the future verb forms as a way of expressing something that is probable or supposed. There is no real verb-only equivalent in English; usually we would express such a thought by using probably, likely, I suppose or some similar word or phrase. In question form, the future tense can indicate uncertainty rather than probability. Here are examples of such usages of the Spanish future tense with possible translations: Pablo no est aquà ­. Estar en casa. (Paul isnt here. Hes probably at home.) ¿Quà © hora es? Ser la una. (What time is it? I suppose its 1 oclock.)Han trabajado mucho. Estarn cansados. (Theyve worked hard. They must be tired.)Estoy confudida.  ¿Me amar? (Im confused. I wonder if he loves me.) Keep in mind that the understanding of such sentences, and therefore the translation, will often depend on the context. For example, estar en casa could mean both he/she will be at home or he/she probably is at home, depending on what else is said in the conversation. And of course, the same is true when translating to Spanish. In the third example above, deben estar cansados would not be a correct translation, because they must expresses probability rather than obligation. Ways of Talking About the Future in Spanish There are at least three ways of expressing the future in Spanish without using the future tense. Periphrastic Future The most common way is to use a form of the verb ir (to go), followed by a and an infinitive. Voy a salir. (I am going to leave.)Van a comprar un coche. (They are going to buy a car. ) ¿Vas a estudiar? (Are you going to study?) This use of ir a is so common that it is popularly thought of as the future tense in some areas and mostly replaces the standard future in everyday speech. This way of discussing the future is known as the periphrastic future tense. Using the Indicative Present for Future Actions In some cases, as in English, it is possible to use the present tense to tell of future events. Sale el tren a las ocho. (The train leaves at 8.)La fiesta de pelà ­culas comienza esta noche. (The film festival begins tonight.)Llega Paulina a las siete de la tarde. (Paulina arrives at 7 p.m. tonight.) This type of present-as-future is most common for scheduled events occurring in the near future. Using the Subjunctive Present for Future Actions Finally, Spanish sometimes uses the present subjunctive where we would use the future indicative in English. Dudo que ella vaya, (I doubt she will go.)Espero que haga buen tiempo, (I hope the weather will be good.)Lo siento que salgas, (I am sorry you will leave.) Often when discussing a future event, the subjunctive doesnt express something that definitely will happen, but rather events that might or wont happen. In other cases, the subjunctive will be used in a sentence that focuses on the reaction to a future event, as in the third example above. Key Takeaways The future tense in both Spanish and English can be used for emphatic commands.In Spanish but not English, the future tense is sometimes used to indicate that a verbs action is likely or that the speaker is supposing that it will happen.In both languages, the present indicative tense can be used to say something will happen in the near future.

Issues in Human Sexuality Unit 3 Essay Example | Topics and Well Written Essays - 750 words

Issues in Human Sexuality Unit 3 - Essay Example Despite this fact, I would state my agreement with the statute based on objective arguments culled from empirical evidence and not because of some emotional bias and the influence of popular sentiment. To understand my standpoint, it is imperative for us to explore the rationale behind the chemical castration. Here, using drugs such as the Depo-Provera or the Tamoxifen, the law seeks to prevent sexual molestation by inhibiting hormones that produces the testosterone or the aromatase enzyme in male offenders. The idea is that when the sexual urge in the offenders are lessened it is expected that the likelihood of committing the crime again is also reduced. Background The Megan’s Law has been the statute that we relied on to keep our children safe from child molesters. The statute requires the identification of sex offenders publicly mainly for preventive purposes. Unfortunately, as years passed statistics reflected a disturbing experience as the logistical demands of enforcing the law is difficult for state governments. A 1998 federal court ruling in New York is one of such illustrations. Here, the state is required to provide the court with the determination of the risk level identification of sex offenders. However, by 2004 the huge number of cases that needed hearing in line with such directive created an unwieldy backlog and in an attempt to fast track the hearings, the risk levels of all offenders were reduced to Level 1, the lowest risk level. (Schultz, p. 185) The effect is that justice is delayed and there is a risk of error in its dispensation.
