Microorganisms: Normal Flora

Microorganisms: Normal Flora The idea of contamination in the host-parasite relationship is communicated in the bodys ordinary greenery. Ordinary greenery is a populace of miniaturized scale creatures that contaminate the body without causing ailment. A few creatures set up a lasting relationship, as E.coli is constantly found in internal organs of people; others like streptococci are transient. Harmonious relationship among body and its ordinary verdure exist at various levels. These might be as mutualism or commensalisms. Lactobacillus in human vagina is instances of mutualism. They get nourishment from vaginal condition and the corrosive created by them forestalls the abundance of different microorganisms. E. coli exists as a commenssal, however may likewise now and again exist in mutualistic affiliation. Typical verdure exists on skin oral cavity, upper respiratory tract, last piece of small digestive system and the internal organ. In digestion tracts there are Bacteroides, Clostridium (spores), Streptococci, Gram positive poles including Enterobacter, Klebsiella, Proteus and Pseudomonas, E. coli ,Candida albicans. Typical verdure experiences changes because of interior condition of the body. Normally, when one says I have a contamination they intend to state I have an infection, anyway the last isn't exactly so socially satisfactory. Indeed, we are completely contaminated with an assortment of microorganisms all through our whole lives. Inconceivably, our bodies are really made out of more bacterial cells than human cells; while the human body is comprised of around 1013 human cells, we harbor close to 1014 microscopic organisms. This gathering of life forms, generally alluded to as typical verdure (despite the fact that they are not plants) is made out of a genuinely steady arrangement of genera, for the most part anaerobes. While every individual has a generally one of a kind arrangement of typical greenery, individuals from the Streptococcus and Bacteroides make up a huge level of the occupants. These living beings add to our reality in a few different ways. These ordinary vegetation may: à ¯Ã¢â‚¬Å¡Ã¢ · Help us by contending with pathogens, for example, Salmonella à ¯Ã¢â‚¬Å¡Ã¢ · Help us by giving nutrients or dispensing with poisons (for example Bacteroides) à ¯Ã¢â‚¬Å¡Ã¢ · Harm us by advancing ailment (for example dental caries) à ¯Ã¢â‚¬Å¡Ã¢ · Cause neither assistance nor hurt (for example commensals). One of the most significant elements of our ordinary greenery is to shield us from profoundly pathogenic life forms. For instance, in a typical (bacterially possessed creature), around 106 Salmonella must be ingested so as to cause malady. In any case, when a creature has been kept up in a sterile domain an incredible entirety (a gnotobiotic creature), a similar degree of sickness can be delivered by as not many as 10 Salmonella. This emotional contrast is basically because of rivalry (wikiAnswers.com). To a microorganism, the human body appears to be a lot of like the planet Earth appears to us. Much the same as our planet, our bodies contain various situations, extending from dry deserts (for example the lower arm) to tropical woods (for example the perineum) to amazingly antagonistic areas (for example the intestinal tract). Every condition has certain points of interest and weaknesses and various microorganisms have adjusted to specific locales of the body for their specific needs. In created nations, PCs are utilized in the bedside zone for numerous capacities, including requesting, checking research facility and picture results, recording patients conditions, what's more, bookkeeping. In addition, most PC gadgets, for example, consoles and mice, in numerous nations are not water-confirmation and not extraordinarily intended for emergency clinic cleansing needs. Along these lines, there is a decent chance that PC interface surfaces may fill in as supplies for nosocomial pathogens. Plus, the pace of hand washing consistence in human services foundations is low (~40%), which is probably identified with the sullying of lifeless surfaces of clinical types of gear and medical clinic condition with nosocomial pathogens (Boyce JM,Pittet 2002). Studies have demonstrated that the hands or gloves of medicinal services laborers (HCWs) can be defiled in the wake of contacting lifeless things in persistent rooms or subsequent to contacting natural surfaces close to patients (Bhalla An et al., 2004 ;Hartstein AI et al.,1988).One study detailed that microbial sullying of PC interface surfaces was pervasive to such an extent that different microorganisms were disengaged from over half of the consoles of emergency clinic PCs (Rutala WA et al., 2006). The degrees of pollution fluctuated with the vicinity to the patients, the surface of lifeless surfaces and the recurrence of contact. The medical clinic ward PC is seen being more uncertain as tainted than bedside PCs (Neely AN et al.,2005). Schultz et al. have detailed that 95% of consoles in closeness to quiet locales had bacterial pollution. Be that as it may, just 5% of these were pathogens known to be related with nosocomial transmission (Schultz M et al.,2003). Most past examinations have detailed the pollution of PC interface surfaces by potential pathogens, for example, Methicillin-safe Staphylococcus aureus (MRSA) (Boyce JM et al.,1997;Bures S et al.,2000) and Acinetobacter baumannii (Neely AN et al.,1999), however few have considered the connection between tainting of the ward PCs and clinical secludes in medical clinics with improved hand cleanliness consistence and during a non-flare-up period. Clinically, A. baumannii, P. aeruginosa, and MRSA cause the most widely recog nized nosocomial diseases and their essence associates with natural surface sullying (Engelhart S et al.,2002;Sekiguchi J et al.,2007).We directed a medical clinic based observation investigation of these three significant pathogens on PC interface surfaces in various ward settings and afterward analyzed the relationship of debased PC interface surfaces with the nearness of clinical separates in these wards during a non episode period. Skin gives genuine instances of different microenvironments. Skin areas have been contrasted with geographic locales of Earth: the desert of the lower arm, the cool woods of the scalp, and the tropical timberland of the armpit. The creation of the dermal smaller scale greenery fluctuates from site to site as per the character of the microenvironment. An alternate bacterial verdure describes every one of three districts of skin: (1) axilla, perineum, and toe networks; (2) hand, face and trunk; and (3) upper arms and legs. Skin destinations with incomplete impediment (axilla, perineum, and toe networks) harbor a bigger number of microorganisms than do less blocked territories (legs, arms, and trunk). These quantitative contrasts may identify with expanded measure of dampness, higher internal heat level, and more prominent centralizations of skin surface lipids. The axilla, perineum, and toe networks are more much of the time colonized by Gram-negative bacilli than are drier zones of th e skin. The quantity of microscopic organisms on a people skin remains generally consistent; bacterial endurance and the degree of colonization most likely rely halfway upon the presentation of skin to a specific situation and somewhat on the natural and species-explicit bactericidal action in skin. Likewise, a serious extent of particularity is associated with the adherence of microorganisms to epithelial surfaces. Not all microbes join to skin; staphylococci, which are the significant component of the nasal greenery, have a particular favorable position over viridans streptococci in colonizing the nasal mucosa. Then again, viridans streptococci are not found in enormous numbers on the skin or in the nose however command the oral vegetation. The microbiology writing is conflicting about the thickness of microorganisms on the skin; one purpose behind this is the assortment of strategies used to gather skin microscopic organisms. The clean technique yields the most elevated and most exact means a given skin zone. Most microorganisms live in the shallow layers of the layer corneum and in the upper pieces of the hair follicles. A few microscopic organisms, in any case, live in the more profound zones of the hair follicles and are past the compass of normal purification techniques. These microorganisms are a store for recolonization after the surface microbes are evacuated. Staphylococcus epidermidis S. epidermidis is a significant occupant of the skin, and in certain territories it makes up in excess of 90 percent of the inhabitant vigorous greenery. Staphylococcus aureus The nose and perineum are the most widely recognized locales for S. aureus colonization, which is available in 10 percent to in excess of 40 percent of typical grown-ups. S. aureus is pervasive (67 percent) on vulvar skin. Its event in the nasal sections differs with age, being more prominent in the infant, less in grown-ups. S. aureus is amazingly normal (80 to 100 percent) on the skin of patients with certain dermatologic sicknesses, for example, atopic dermatitis, yet the purpose behind this finding is muddled. Micrococci Micrococci are not as regular as staphylococci and diphtheroids; be that as it may, they are much of the time present on typical skin. Micrococcus luteus, the transcendent species, for the most part represents 20 to 80 percent of the micrococci disconnected from the skin. Diphtheroids (Coryneforms) The term diphtheroid signifies a wide scope of microscopic organisms having a place with the family Corynebacterium. Characterization of diphtheroids stays unacceptable; for accommodation, cutaneous diphtheroids have been sorted into the accompanying four gatherings: lipophilic or nonlipophilic diphtheroids; anaerobic diphtheroids; diphtheroids delivering porphyrins (coral red fluorescence when seen under bright light); and those that have some keratinolytic compounds and are related with trichomycosis axillaris (disease of axillary hair). Lipophilic diphtheroids are amazingly regular in the axilla, though nonlipophilic strains are discovered all the more ordinarily on glabrous skin. Anaerobic diphtheroids are generally regular in zones wealthy in sebaceous organs. In spite of the fact that the name Corynebacterium acnes was initially used to depict skin anaerobic diphtheroids, these are presently delegated Propionibacterium acnes and as P. granulosum. P. acnes are seen multiple times more much of the time than P. granulos

Martin Luther King Junior Essays - Anglican Saints,

Martin Luther King Junior On a run of the mill day in 1929 a man was conceived. A man that would follow in his dads strides to turn into an extraordinary American pioneer. A pioneer, yet in addition somebody that would move individuals everything being equal. A man that thought about his individual individuals and would not surrender for anything. He would attempt to battle. Attempt to win. Attempt to guarantee harmony for our reality. This man is the unrivaled Martin Luther King Junior. This man is one of history's best-cherished and regarded motivations. Conceived in Atlanta, Georgia, Martin Luther King Junior was brought into our reality with what appeared just as a light consuming in his heart. Flashing to accomplish objectives, and giving light and love to our individual individuals. As a kid he would carry on with an actual existence that to him wasn't fit for him. His companions appeared to be just individuals that looked equivalent to him. A similar skin shading. During an amazing beginning, he was unable to get why. Despite the fact that he just conversed with individuals of his own race he was fulfilled, however not for long. As he developed more established he started to comprehend. He was at long last acknowledging why he was caught behind the mass of preference. The considerations in his brain started to venture into a world that was difficult to live with. He started to battle in school and every day life at home. His contemplations were bolted on just one objective. Martin Luther King Junior moved on from Morehouse College in Georgia in 1948 and he was prepared to take obligations like a grown-up. after 3 years in 1955 he moved on from Crozer Theological Seminary. His folks adored his incredible learning capacities however frequently hoped for something else from him. They were glad yet instructing. He concentrated hard to make his folks pleased, however he felt that it was a colossal advantage for him too. He took a Ph.D. from Boston University in 1955 and was on the thruway to progress. He had decent training, a consistent family, and that was not all. While going to class at Boston University Martin Luther King Junior met his future spouse. He didn't have a clue about the genuine importance of affection until he discovered her. His life changed, and could never again be the equivalent. Alongside another spouse new duties. Coretta Scott and Martin Luther King Junior marry. Not long after their marriage they had four children together. As Martin would like to think, he was the most fortunate man on the planet. To him nothing could be superior to a sound cheerful marriage, and solid upbeat children. He had his life spread out like a camping cot. On the off chance that you recollect the existence that Martin Luther King lived, he gave his central core into what he accepted, and he wouldn't surrender until he accomplished his objective that was on the highest priority on his rundown. I'm certain that his rundown was exceptionally not insignificant rundown, and I realize that in the course of his life he accomplished each and every one of them. I genuinely perceive how Martin Luther King Junior is a noteworthy bit of history, and that he is a motivation for opportunity. In 1953 Martin became minister of the Dexter Avenue Baptist Church in Montgomery. He concluded that battling for what he put stock in was the best activity. In 1957 Martin Luther King Junior was picked to be leader of the recently shaped Southern Christian Leadership Conference. Officially known as SCLC. He started to

Tales of a College Froshling

Tales of a College Froshling When I went online to start typing up this post, I noticed an unpublished post of mine from nearly three weeks ago. Apparently I started writing an apologies for being too hosed to post entry and never finished it, which is just as well because I dont know what was going to be in it and dont recall ever writing the thing anyway. Ive always liked being insanely busy, but this is just ridiculous. Lets try this again. So whats been up with me? I passed my finals, and I can even tell all my friends that I have a 4.0 at MIT! Granted, none of them know that we use a 5.0 scale, but thats not the point. I have a B average. At MIT. I am dancing. Im also back in Florida, having moved out of Senior House for the summer. After some panic that Id be jobless and living in a cardboard box under Harvard Bridge for two and a half months, I was offered a job as an RA for the Center for Talent Development at Northwestern University, where for six weeks, Ive be living and working with middle school students taking introductory high school classes through the program. This is a source of great excitement for Hanna 10, who lives near Evanston and is already planning to accidentally-on-purpose show up at scheduled activities in the area. (So lets all go out for ice cream! And what a surprise, weve managed to bump into my good friend Hanna again! Um, well..) Not that Im complaining were suffering from radio show depr ivation and no longer responsible for our actions. Until I leave in two weeks, though, Ill be at home hanging out with my friends and family, along with sewing a lot. Hey, its been a while. Ill also spend a good amount of time reading the textbooks I got for my birthday. By the way, I turned eighteen on the 14th. Woo! I can be tried as an adult now! Anyway, Ive been emailing a few of you back and forth about all things MIT (and lets not ignore the messages and wall posts on the all-powerful Facebook); you all have brought up some useful topics that Id like to address here. Since the Freshman Housing Lottery just opened two days ago, lets start with that one. By now, you incoming frosh should probably have a general idea of how the whole thing works. You look through the information available to you (such as living group websites and the Guide to Residences in last months huge mailing), ask current students a million questions about what the dorms are like, rank all 15 16 (i-House is starting up this fall in New House 1, formerly Russian House) living groups in order of preference, and stick the list under your pillow just before you go to bed. That night, the magical Housing Fairy quietly removes the list from beneath your sleeping form, leaving a $2800 charge for next semesters room in its place. scratch that last part. I think I just mixed this up with the stories my mom used to tell me when I was five. All right, so you submit this list to MIT, where a computer puts everyone in a dorm using an algorithm designed to maximize the number of people in their first-choice living group. The room assignment chairs in each living group then use the rest of your application all the stuff about your number of desired roommates, likes and dislikes, et cetera to put you in a temporary room. Dont get too comfortable in your temp room; youll almost definitely be moving again. This is what REX (which some people refer to as Dorm Rush, a throwback to the way the housing system used to work before all frosh were required to live on campus starting in 2002) is for once youre actually here at MIT, its far easier to check out all the dorms and cultural houses for yourself. (Many of you started doing this during CPW.) We try to give you everything you need to make an informed decision, but theres really no replacement for going and spending some time everywhere. At the end of August, after youve been here for about a week, theres an Adjustment Lottery. In the lottery, you can decide to stay in your temporary dorm or enter up to four places youd like to move. Some of you will be happy where you are, and you may just want a different roommate or a room on another floor; of course, you might also decide to move somewhere entirely different. I got my second choice dorm in the Housing Lottery and got to MIT with the intent of checking everywhere out, since I wasnt completely happy with where Id been placed anyway. By the end of the Adjustment Lottery, I was moving clear across campus to a dorm that was originally my sixth choice. Once youve been assigned your final dorm, an In-House assignments are held to determine your final room. Each dorm handles this differently; while Baker and Next both hold numbered lotteries, Senior House makes you fill out a sheet with your top choice rooms and explain why the room assignment chairs should care about what you want. This explanation may or may not be in the form of baked goods. (Just For Fun: Click on this link and scroll down to the picture of Senior House. See the windowsill halfway painted blue? That was my room last term. A couple of years ago, someone living there decided to paint everything in the room that shade of blue, including the speaker for the fire alarm, the overhead storage shelves, the ceiling, and half the windowsill. By the time I got there, most of it had been painted over with Institute White, but the blue just wont go away.) It all seems really complicated, especially now that your friends going to other schools are all starting to get word of their roommates names, along with the locations of their bed, desk, chair, hall bathroom, complimentary loveseat, and the like.We just want you to be happy here. If you can have the option of deciding where to live, then why not give it to you? Ill end this post with links to some dorm tours put up by myself and the other bloggers: Baker House Burton-Conner House East Campus: one and two MacGregor House Next House Random Hall Senior House: one and two And heres a post Jessie put up a while back, which is really helpful and explains things better than I could have done. Any more questions? Email me! All the cool kids are doing it. ^_^

Critical Indicator of Business Success: The Ability to Innovate INTRODUCTION This report aims to investigate the ability to innovate is becoming a critical indicator of business success. With the globalization of the world today, business have become more competitive and succeeding in the business environment have become more challenging, requiring more drastic measures such as adaptability in changing environment and ability to innovate as compared to decades past. This investigation is conducted in order to identify the key factor that drives a business success with focus on the ability for the business to innovate as a critical indicator of business success. Don’t waste time! Our writers will create an original "Critical Indicator of Business Success: The Ability to Innovate" essay for you Create order The investigation is carried out by reviewing current and past surveys conducted by various researchers in different business environment. Compares of business goal attainment is made between highly innovative business and less innovative business in different business environment. Based on research, it was discovered that for companies to remain competitive they need to nimbly and respond quickly to the changing business environment without getting caught in knots. It is important for companies to posses the ability to respond to market movement by transforming information into insight as core to sustainability. The main constraints to improved business success mostly are conflicting departmental goals and priorities, slow decision-making, silo-based information and risk-averse cultures. Companies are at a competitive disadvantage if they are not agile enough to anticipate fundamental market place shift. These are theories made from past research and survey and here is where inno vative activities come in. This report discusses the different highlights, review, debates and current discussions on the innovative effect of business system on the success outcome of the business (Andy Jasper 1998). INNOVATION AS A CRITICAL INDICATOR FOR SUCCESS Many companies will treat innovation as black-box, the serendipitous achievement of a few gifted individuals. But this survey found that innovation leaders consistently outperformed laggards on five manageable capability areas. In the past, most successful companies were duopolies or mono polices as compared to recent times were free market trade, globalization and the ability to satisfy the customers expectation is the key to profitability. Innovation involves exploiting new ideas resulting in the creation of new services, product or process. It is not just the development of a new idea that is important, but bringing the idea into the market and putting it into practice by exploiting it in a way that leads to new services, systems or products that add value and improve quality. This is a critical indicator to most business success as customer satisfaction is fully derived from the product and services and not just for the selfless gain of the company (Eric Almqust 2013). Apple is an example of innovative company as they are able to develop new versions of the iPhone which is similar in nature but still at the same time gain high profitability by the ability to make customers see the uniqueness and need for it. This involves a high level of creativity to succeed above others in the mobile industry. It possibly involves management restructuring and technological transformation. Business innovation involves exploiting new technology and employing out-of-the-box thinking ability to develop new value and to bring out noticeable changes in the economy leading to economic development and growth. Economic growth brings more profitability to the company, this is an after effect derived from innova tive business activities and seen from companies that employ the use of appropriate innovation system in their business activities (Vadim Kotelinikov 2012). Research also shows that if a company is not agile, the rate of success is limited because customers are not static. Current debates shows that planning for the unpredictable may appear to be an impossible irony, but many companies seem to recognize that in a period of economic instability, a company ability to be flexible and positively respond is critical for sustaining growth. Economist have also explored the business market to distinguish companies that employ innovative strategies in their business activities to company to use traditional systems to run their business, based on several market survey is was seen that most of the company still using traditional system to run their business were quick to stumble and fall in the fast growing economy and especially during economic instabilities due to their inability to respo nd to market changes and find a suitable way to meet the customer needs and keep the customer despites reducing purchasing power of the customers. To nurture an environment in which customer centricity and innovation can thrive, those polled during survey emphasized that importance of a high performance culture, accountability, and ability to access the right information at the right time as the key enablers to innovation and hence company profitability and sustainability (UIS 2009). An economist by the name of Mr. Weil from MIT quoted that à ¢Ã¢â€š ¬Ã…“productivity is important as it drives economic growthà ¢Ã¢â€š ¬Ã‚ . Managing in a time of impermanence is easy feat but to compete in the business environment, businesses need to refine organization processes and leverage outside and institutional knowledge more efficiently and effectively. In a nut shell, after the investigation it was found that companies with higher degree of technology and process standardization were mo re agile and agile companies places more focus on standardizing that process that will not change, thereby freeing up resources to develop value added features that do respond to changing customer needs (EMC 2009). Experts have identified various types of innovation such as service or product innovation that involves the introduction of a new service or product that is considerable improved or new, process innovation that entails the implementation of an enhanced production or delivery strategy, supply chain innovation comprising of innovation that transforms the sourcing of input products from the market and delivering of output to customers, and marketing innovation which results in the evolution of new methods of marketing with enhancement in packaging, product design, pricing and promotion among others. This is the sole to sustainable business development. WHY INNOVATION IS IMPORTANT One survey showed that almost 90% of businesses believe that innovation is a priority for them. Measured and planned combination of idea, people and objects results to innovation leading in new business ideas and hence technological revolutions. To achieve valuable innovation, new services and products need to be strong enough to progress through rigorous commercialization process and into the business marketplace. Management expert Peter Drucker stated that à ¢Ã¢â€š ¬Ã…“if a company which in this age necessitating innovation, is not able to innovate, it faces decline and extinctionà ¢Ã¢â€š ¬Ã‚ . Many organizations are employing measures to strengthen their ability to innovate in order to create a dependable operating system for innovation which is an important indicator of corporate sustainability (Amitabh Shuka 2009). Innovation is a popular act in business but one of the hardest to pull off. Bain and Company recently surveyed about 450 executives from different companies around the world and it was discovered that two-thirds of these companies made innovation one of their top priorities. Less than one-quarter believed that their companies were effective innovators and even fewer said they strong at breakthrough innovations (Iraj Nebojsa 2010). The survey found companies that are great in innovation and not just iconic innovators such as Amazon.com, Samsung or Apple. To wrap it up, virtually all the top quartile of investors in the survey agreed with the following statement: They have a winning, repeatable model for innovation that they apply consistently in different regions and categories. They currently have projects that will exceed or meet their financial targets for innovation. They are prepared for market disruptions through innovation. They have consistently met or exceeded their innovation goals. CONCLUSION The importance of innovation is increasing significantly. In todayà ¢Ã¢â€š ¬Ã¢â€ž ¢s economic scenario, innovativeness is becoming a major factor in influencing strategic planning. It has been noted that innovation leads to wealth creation. Although efficiency is important for a business success, in the long term business activities, it cannot sustain the business growth. In the current day, we need innovators more than any time before. Every company and business is feeling the impact of migration, knowledge and technological revolutions, climate change issues, and globalization. Innovation will widen and add more value to the employment base. If the quality of life in these trying circumstances is to improve, innovation is imperative. Innovation will also make the world a better place for the younger generation. Research indicates that strong demand combined with competition is a major drive towards innovation. The intensity of competition is the determinant of prod uctivity and innovation besides services and products also includes new business systems, new management methods and new processes which have a significant impact on productivity and growth.

Schizophrenia is a severe mental disorder which is commonly diagnosed in 15-30 year old individuals. It disrupts a person’s cognition, perceptions and emotions, making it extremely difficult to diagnose. Bleuler (1911) introduced the term schizophrenia, which translates as ‘split-mind’ or ‘divided

Microscopy and the Metric System Margaret E. Vorndam, M. S. We will write a custom essay sample on Lab 2: Microscopy and the Metric System or any similar topic only for you Order Now Version 42-0090-00-01 Lab Report Assistant This document is not meant to be a substitute for a formal laboratory report. The Lab Report Assistant is simply a summary of the experiment’s questions, diagrams if needed, and data tables that should be addressed in a formal lab report. The intent is to facilitate students’ writing of lab reports by providing this information in an editable file which can be sent to an instructor. Exercise 1: Measuring Length, Weight, Volume, and Temperature Try the following conversions for practice. 40,000 ng =0. 24mg =0. 00024g50 cm =500 mm =0. 5m Procedure 1. Length: A metric ruler is useful for measuring items of length. The ruler below measures in mm, indicated by the small mm near 0. a. How many mm are there in 1 cm? 10, in a meter (m)? 1000 (Ruler is not to scale. See ruler in dissection kit. ) b. Locate a measurable object to use for this exercise. If the object is long, obtain a yardstick that includes a cm scale; they can be found in local hardware stores. c. Record the length of the object below and do the conversions: Name of object: ID card . 5 cm=85mm=0. 085m Volume: Always pour an approximate volume of liquid into a clean beaker and then from the beaker into the volumetric flask or graduated cylinder. This will minimize contamination of the parent liquid source. Dispose properly of any leftover liquid. Do NOT pour it back into the original container. Why? This is so the original liquid does not get contaminated. When using a pipet or dropper to measure liquid, pour an aliquot into a clean beaker and then draw up the liquid from the beaker into the pipet. NEVER try to draw up chemicals by mouth. Why? Chemicals could go into your mouth, which is potentially dangerous and should never be done no matter if they deemed â€Å"safe† or not. Weight: Use the pen scale from the lab kit to measure out exactly three grams of sugar. Make sure to tare the bag before adding the sugar. Why must the bag be tared before adding the sugar? This is done so the weight of the bag is not counted with the weight of the sugar. You must think about the weight of the bag when weighing out the three grams of sugar. How is the weight of the bag accounted for when the sugar is weighed? The bag is weighed first and then the 3 g of sugar is added on top of that weight so at the end the weight is more than 3g total due to the bag. Temperature: Practice converting the following with this conversion formula: 45 °F = 7. 2  °C 62 °F =16. 7  °C 98. 6 °F =37 °C Use a Celsius thermometer to measure the  °C temperature of several different aliquots of cold and warm tap water. Make sure to allow the thermometer to remain until the temperature is stable and no longer changes. Record the temperatures: Cold-15 °C Warm – 29 °C Hot- 48 °C Questions A. What laboratory equipment would be used to measure the following items? g flour| Beaker and scale| 36 mL water| Graduated cylinder| The length of a frog’s leg| ruler| 36 g water| Beaker/balance| 38?

F= 35. 56 ? C D. What advantages does the metric system have over the English method of measurement? What are the disadvantages? The metric system is advantageous because it has a base of ten, making measurements easier to take, read, understand, and convert. The prefixes are also standard so they transfer between all measurements. Also, more co untries use the metric system whereas basically only the US uses the English method. The main disadvantage of the metric system is that Americans have not grown up with these measurements so they are harder to picture and understand what distance, weight, etc. ach measurement is. For example, it is much easier for most Americans to understand the distance of a mile than to try and picture how long a kilometer is. E. Outline the steps necessary to accurately weigh 3. 5 g of starch. This depends on the scale used, but with the pen scale included in the labpaq, tare a bag or other container that can be used. Then add in the starch until the weight on the scale reads the weight of the container plus 3. 5 g. F. Outline the steps necessary to accurately pipet 5 mL of distilled water. Pour an aliquot of distilled water into a clean beaker. Put a little more than 5mL of distilled water in a beaker. Pipet 5mL from the beaker, and check to see if the bottom of the meniscus lines up with the 5mL line. Exercise 2: Microscopy The compound light microscope effectively magnifies in the range of 40x to 2000x. If an object under view is 10 nm in length without any magnification, what will be its viewing size at 40x? 400nm at 2000x? 20 ? m What is the equivalent size at these magnifications, in inches? Show your calculations. 400nm*(1cm/10^7nm)*(1in/2. 54cm)= 1. 57*10^-5 in. 20? m*(1cm/10^4? m)*(1in/2. 54cm)= 7. 87*10^-4 in. The scanning electron microscope (SEM) employs electron bombardment to image very small specimens. Electron microscopes are used to image specimens that range from 1 nm to 100  µm in size. What is the equivalent in inches? . Show your calculations. 1nm*(1cm/10^7nm)*(1in/2. 54cm)= 3. 94*10^-8 in. 100 ? m*(1cm/10^4? m)*(1in/2. 54cm)= 0. 0039 in. Procedure 1. Parts of the Compound Light Microscope: Refer to a microscope as this section is read. Label the microscope diagram that follows as the examination of the microscope proceeds. a. Eyepiece (Ocular Lens): The magnification power is stamped on the outside of the lens. What is the power of the ocular lens? Microscopes may have interchangeable ocular lenses of different magnification. 15x b. Body Tube: Holds the ocular and objective lenses at the correct focal distance. c. Arm: Used to transport microscope and hold the body tube. d. Nosepiece: The revolving device that holds the objective lenses. May also be referred to as the turret. e. Objective Lenses: Consists of one or more lenses: i. The scanning power objective lens is the shortest of the lenses. What is its power? 4x ii. The low-power objective is slightly longer than the scanning objective. What is its power? 10x iii. The high-power objective is longer than the low-power objective. What is its power? 40x Label this microscope diagram with the appropriate part names and their functions: Eye piece- lens that you look through Body tube- Piece that leaves distance between lenses Course adjustment knob- adjusts focus Nosepiece- turns the lenses Objective lenses- magnify objects Stage- holds slides Mirror- reflects light so you can see what’s on the slides Base- bottom of microscope allowing stability Arm- Supports the tube and connects everything Eye piece- lens that you look through Body tube- Piece that leaves distance between lenses Course adjustment knob- adjusts focus Nosepiece- turns the lenses Objective lenses- magnify objects Stage- holds slides Mirror- reflects light so you can see what’s on the slides Base- bottom of microscope allowing stability Arm- Supports the tube and connects everything a b c d e f g h i Parts not included in microscope are: Light source Source: Sharma, Abhishake. Labeled Microscope Drawing. N. d. Buzzle. com. 2. Focusing the Microscope: If the microscope includes an oil immersion lens, place a drop of immersion oil on the slide cover slip before rotating the lens into place. The function of the oil is to minimize light diffraction through the slide and subject so that greater detail can be seen. After using the oil immersion lens, clean excess oil off of the lens and the slide with a lens cloth. Never tilt a microscope when using oil or if viewing a wet slide. Why? The liquid could come off of the slide and get into a place in the microscope that isn’t good for it, and it will be messy also. 3. Operating the Microscope: a. Obtain a clean slide and cover slip from the slide box. Place the slide and cover slip separately on a paper towel or other soft surface to reduce the possibility of scratching them. . With scissors, cut a letter â€Å"e† from an old magazine or newspaper. c. Place the letter in the center of the slide. d. Follow the instructions in Section 6 below to make a wet mount of the letter. e. Following the directions outlined above under Handling and Focusing the Microscope, place the prepared slide on the microscope stage. Leav e the scanning lens in place and focus so that the letter is clearly viewable. Make drawings of the letter in the boxes below as instructed. Side of the slide furthest away from student| Look from the side of the microscope, viewand then draw the letter here, as it appears onthe slide on the stage. | e e Draw the letter here as it appears when viewing it through the microscope. | Side of the slide closest to student| f. What is observed? Microscopes invert the image on the slide. This means that the subject will appear to be 180 ° rotated and reversed from the actual image viewed on the slide. g. While viewing the letter through the lenses, move the slide slightly. What do you observe about the movement of the letter and slide when viewed through the lenses? When I move the slide up, what I’m viewing moves down. When I move the slide to the left, the image moves right. . Use the directions above to view the letter at the higher objective powers. On the drawing made above, c ircle the portion of the letter that is viewable as successively higher power observations are made. What is your conclusion about what happens when higher power objectives are used? Only a piece of the top part is viewable. Higher power objectives magnify the image more. 4. Total Magnification Calculation: Typically, the ocular lens of a microscope will be 10x, but it may be higher or lower. The power is recorded on the side of the lens. a. What is the ocular lens power of the microscope that you are using? It may be 10x or 15x. Record it in Table 1. b. The objective lenses also have the magnification power recorded on their sides. What powers do the objective lenses on the microscope have? Record them in Table 1. c. Now, calculate the total magnification of the viewing area by multiplying the power of the ocular lens with that of the objective lens in use. For instance, if a microscope has a 10x magnification ocular lens and a 4x objective lens in place for viewing, the total magnification will be 40x (10x multiplied by 4x). What other view magnifications are possible with the microscope? Calculate the total magnification for each set of lenses in Table 1. Table 1: Calculating Magnification Ocular Lens Magnification x| Objective LensesMagnification =| Total Magnification| 15x| 4x| 60x| | 10x| 150x| | 40x| 600x| 5. Diameter of Field: a. With the low-power objective in viewing position, place a short transparent metric ruler on the stage. b. While viewing the ruler through the lenses, measure the low-power diameter of field of view in mm. Convert this measurement to ? m and record in Table 2. c. Switch to the other higher power objectives, noting the diameter, in mm, for each in Table 2. Convert measurements to ? m. How might this information be useful when viewing microscopic subjects? Micrometers are smaller, so it is useful for very small objects when mm would be a very small number that wouldn’t be very understandable.

Schizotypal Personality Disorder free essay sample

Schizotypal personality disorder Explanation: People with schizotypal personality disorder are more comfortable turning away from others, rather than learning to have meaningful interpersonal relationships. This isolation contributes to distorted perceptions about how interpersonal relationships are supposed to happen. A person with schizotypal personality disorder has odd behaviors and thoughts that would typically be viewed by others as eccentric, erratic, and bizarre. They are known on occasion to have brief periods of psychotic episodes.Their speech, while coherent, is marked by a focus on trivial detail. Thought processes of schizotypals include magical thinking, suspiciousness, and illusions. These thought patterns are believed to be the schizotypals unconscious way of coping with social anxiety. To some extent, these behaviors stem from being socially isolated and having a distorted view of appropriate interpersonal relations. Causes: Schizotypal personality disorder is believed to stem from the affected persons original family, or family of origin.Usually the parents of the affected person were emotionally distant, formal, and displayed confusing parental communication. We will write a custom essay sample on Schizotypal Personality Disorder or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page The social development of people with schizotypal personality disorder shows that many were also regularly humiliated by their parents, siblings, and peers resulting in significant relational mistrust. Many display low self-esteem, self-criticism and self-deprecating behavior. This further contributes to a sense that they are socially incapable of having meaningful interpersonal relationships.How it is diagnosed: The symptoms of schizotypal personality disorder may begin in childhood or adolescence showing as a tendency toward solitary pursuit of activities, poor peer relationships, pronounced social anxiety, and underachievement in school. The bizarre thinking associated with schizotypal personality disorder can be perceived as a psychotic episode and misdiagnosed. Symptoms: 1. Incorrect interpretations of events 2. Odd beliefs or magical thinking 3.Unusual perceptual experiences 4. Odd thinking and speech 5. Suspicious or paranoid thoughts 6. Emotionally inexpressive 7. Eccentric behavior 8. Lack of close friends 9. Socially anxious Treatments: 1. Psychodynamically oriented therapies 2. Cognitive-behavioral therapy 3. Interpersonal therapy 4. Group therapy 5. Family and marital therapy Medications: 1. Among the most helpful are antipsychotics 2. Amoxapine – which is an antidepressant with antipsychotic properties 3. Prozac
