Principle of Account Essay Example for Free

Principle of Account Essay A microscope is an instrument used to see objects that are too small for the naked eye. The science of investigating small objects using such an instrument is called microscopy. Microscopic means invisible to the eye unless aided by a microscope. There are many types of microscopes, the most common and first to be invented is theoptical microscope which uses light to image the sample. Other major types of microscopes are the electron microscope (both the transmission electron microscope and the scanning electron microscope) and the various types of scanning probe microscope. Microscope 1. An optical instrument, consisting of a lens, or combination of lenses, for making an enlarged image of an object which is too minute to be viewed by the naked eye. Parts and Specifications Historians credit the invention of the compound microscope to the Dutch spectacle maker, Zacharias Janssen, around the year 1590. The compound microscope uses lenses and light to enlarge the image and is also called an optical or light microscope (vs. an electron microscope). The simplest optical microscope is the magnifying glass and is good to about ten times (10X) magnification. The compound microscope has two systems of lenses for greater magnification, 1) the ocular, or eyepiece lens that one looks into and 2) the objective lens, or the lens closest to the object. Before purchasing or using a microscope, it is important to know the functions of each part. Eyepiece Lens: the lens at the top that you look through. They are usually 10X or 15X power. Tube: Connects the eyepiece to the objective lenses Arm: Supports the tube and connects it to the base Base: The bottom of the microscope, used for support Illuminator: A steady light source (110 volts) used in place of a mirror. If your microscope has a mirror, it is used to reflect light from an external light source up through the bottom of the stage. Stage: The flat platform where you place your slides. Stage clips hold the slides in place. If your microscope has a mechanical stage, you will be able to move the slide around by turning two knobs. One moves it left and right, the other moves it up and down. Revolving Nosepiece or Turret: This is the part that holds two or more objective lenses and can be rotated to easily change power. Objective Lenses: Usually you will find 3 or 4 objective lenses on a microscope. They almost always consist of 4X, 10X, 40X and 100X powers. When coupled with a 10X (most common) eyepiece lens, we get total magnifications of 40X (4X times 10X), 100X , 400X and 1000X. To have good resolution at 1000X, you will need a relatively sophisticated microscope with an Abbe condenser. The shortest lens is the lowest power, the longest one is the lens with the greatest power. Lenses are color coded and if built to DIN standards are interchangeable between microscopes. The high power objective lenses are retractable (i. . 40XR). This means that if they hit a slide, the end of the lens will push in (spring loaded) thereby protecting the lens and the slide. All quality microscopes have achromatic, parcentered, parfocal lenses. Rack Stop: This is an adjustment that determines how close the objective lens can get to the slide. It is set at the factory and keeps students from cranking the high power objective lens down into the slide and breaking things. You would only need to adjust this if you were using very thin slides and you werent able to focus on the specimen at high power. Tip: If you are using thin slides and cant focus, rather than adjust the rack stop, place a clear glass slide under the original slide to raise it a bit higher) Condenser Lens: The purpose of the condenser lens is to focus the light onto the specimen. Condenser lenses are most useful at the highest powers (400X and above). Microscopes with in stage condenser lenses render a sharper image than those with no lens (at 400X). If your microscope has a maximum power of 400X, you will get the maximum benefit by using a condenser lenses rated at 0. 5 NA or greater. 0. 65 NA condenser lenses may be mounted in the stage and work quite well. A big advantage to a stage mounted lens is that there is one less focusing item to deal with. If you go to 1000X then you should have a focusable condenser lens with an N. A. of 1. 25 or greater. Most 1000X microscopes use 1. 25 Abbe condenser lens systems. The Abbe condenser lens can be moved up and down. It is set very close to the slide at 1000X and moved further away at the lower powers. Diaphragm or Iris: Many microscopes have a rotating disk under the stage. This diaphragm has different sized holes and is used to vary the intensity and size of the cone of light that is projected upward into the slide. There is no set rule regarding which setting to use for a particular power. Rather, the setting is a function of the transparency of the specimen, the degree of contrast you desire and the particular objective lens in use. How to Focus Your Microscope: The proper way to focus a microscope is to start with the lowest power objective lens first and while looking from the side, crank the lens down as close to the specimen as possible without touching it. Now, look through the eyepiece lens and focus upward only until the image is sharp. If you cant get it in focus, repeat the process again. Once the image is sharp with the low power lens, you should be able to simply click in the next power lens and do minor adjustments with the focus knob. If your microscope has a fine focus adjustment, turning it a bit should be all thats necessary. Continue with subsequent objective lenses and fine focus each time. What to look for when purchasing a microscope. If you want a real microscope that provides sharp crisp images then stay away from the toy stores and the plastic instruments that claim to go up to 600X or more. There are many high quality student grade microscopes on the market today. They have a metal body and all glass lenses. One of the most important considerations is to purchase your instrument from a reputable source. Although a dealer may give you a great price, they may not be around next year to help you with a problem. One dealer that we can highly recommend is Microscope World. They offer a wide variety of instruments at very competitive prices.

Essay --

The 14th Vienna Secessionist exhibition (1902) was dedicated to the appreciation and celebration of Ludwin van Beethoven. The famous and renowned German composer that had influenced thousands with his music. Gustav Klimt created his Beethoven frieze for this exhibition. The work of art was originally intended to be destroyed after the exhibition. It was applied directly to the walls with light materials so that its removal would be quick and easy. The Beethoven frieze is painted along the upper half of three walls. The paintings of the walls tell a story with the left wall being the beginning and the right wall being the end. The work of art was a 34 meter long frieze and was applied onto the wall with casein paint, gold paint, chalk, and graphite on plaster. The Frieze survived because it was bought by a collector before the exhibition came to a close. The collector had it cut into 8 pieces for transportation and the Frieze was not seen for another 80 years. Later, in 1973 the Austr ian Republic bought and restored it and placed it on permanent display in the Vienna Secession Building. The first long wall of the Beethoven frieze marks the beginning of a story. It begins with a series of elongated female figures that seem to flow along the top of an empty space. Their eyes are closed and some have their arms extended in from of them as if they were trying to reach out to something. They almost seem to represent the soul’s longing for peace and tranquility. Flowing into the background of the first predominant painting. This part of the Frieze shows, a family praying or begging to a noble knight. The family is completely naked with an overlying sense of poverty and suffering. It shows the father and mother figure on their knees wit... ...e frieze find their place when they come upon a woman playing a lyre. The lyre signifies poetry and music while the woman is a muse to for the human soul. The Last portion of the frieze shows the female figures once again but their arms are no longer reaching out and their faces have a sense of satisfaction. Their bodies are curved as if dancing to the sound of music. To the right of them there is a choir of women that seem to be singing. Since the Frieze was painting for the celebration of Beethoven it is believed that the choir is singing ode to joy. In between the choir there is what seems to be an altar where a man and a woman are holding each other tightly. The sun and the moon hang on either side of the man and woman. This portion of the frieze has been titled â€Å"A kiss to the world†. Neither of their heads are visible and their feet are bound together by water

Funding Opportunities for Small Businesses Essay

Analyze funding opportunities for small businesses, including the role of the Small Business Administration (SBA). Then, evaluate the effectiveness of these funding opportunities in light of the current economy. In this time of economic challenges, suggest two ways that the SBA might be of assistance to your small business. Explain how you would request this assistance. Small businesses are leaders in innovation and drivers of the economy. Small businesses hold more patents than all of the nation’s universities and largest corporations combined, and create two thirds of all private sector jobs, employing half of all working Americans. The Federal government is the largest buyer in the world, spending over $500 billion each year. For the Federal government, contracting with small businesses is common sense. Small businesses get the revenue they need to create jobs and drive the economy forward, and federal agencies get the creativity, innovation, and technical expertise of small businesses to help accomplish their mission. When small businesses are excluded from federal contracts, the Federal government, American taxpayers and the nation’s economy lose out. Over 30 years ago, Congress set a goal of having a certain portion of all federal contracting dollars go to small businesses and established sub-goals for small businesses owned by women, socially and economically disadvantaged individuals, and service-disabled veterans of the Armed Forces, and for small businesses in Historically Underutilized Business Zones (HUBZones). The current government-wide goal for small businesses’ share of contracting dollars is 23%. Every year since 2006, the Federal government has missed the 23% small business goal and all but one of the sub-goals; the 2009 shortfall was greater than $4 billion. Removing barriers to federal contracting and increasing access for small businesses will go a long way in closing this gap. Over the past 18 months, the Federal government has taken important steps to increase opportunities for small businesses, from creating new online training for small businesses to issuing a proposed rule to create set-asides for women-owned small businesses in industries in which women are underrepresented. Last summer, the Department of Commerce and the Small Business Administration (SBA) co-led a government-wide effort that involved over 300 matchmaking and training events across the country to ensure American Recovery and Reinvestment Act (Recovery Act) contracts were awarded to a broad array of small businesses. With over 31% of Recovery Act contracting dollars going to small businesses, this initiative 2 Report on Small Business Federal Contracting Opportunities proved that, with committed leadership and the right tools, the government has the ability to meet – and exceed – the 23% small business contracting goal. Stronger rules. Insufficient guidance and gaps in current policy hamper the use of tools that provide contracting opportunities for small businesses. The Task Force recommends actions to strengthen and update policies where they are weak or outdated and develop policies where they are lacking. A better equipped, more informed and more accountable acquisition workforce. A lack of knowledge and agency accountability inhibits the government’s ability to meet and exceed small business procurement goals on an ongoing basis. The Task Force recommends increasing the knowledge base and efficiency level of the procurement workforce and providing appropriate incentives and accountability for agencies to meet small business goals. Improved outreach and better use of technology and data. The current data systems in the federal acquisition environment are cumbersome and not user friendly for many small businesses, especially for those who are new to the systems and trying to â€Å"get the ir foot in the door.† The Task Force recommends a one-stop shop for easier access to procurement information, as well as greater focus on the accuracy of procurement data. In the following report, the Task Force outlines the key recommendations and actions needed to meet these priority objectives. The Task Force will report to the President by December 30, 2010, on progress in the implementation of the recommendations in this report. SBA, Commerce, OMB, and the other members of the Task Force are committed to increasing opportunities for small businesses. Small businesses, including businesses owned by women, socially and economically disadvantaged individuals, and service-disabled veterans of our Armed Forces, must be able to participate in the Nation’s economic recovery. They must be able to compete effectively for federal contracts so our agencies, taxpayers, and the broader economy can reap the full benefit of their talents and services. 3 Report on Small Business Federal Contracting Opportunit ies REPORT INTERAGENCY TASK FORCE ON FEDERAL CONTRACTING OPPORTUNITIES FOR SMALL BUSINESSES Small businesses are leaders in innovation and the drivers of the economy– holding more patents than all of America’s universities and largest corporations combined, creating two thirds of all private sector jobs and employing half of all working Americans. The Federal government is the largest buyer in the world, spending over $500 billion each year. For the Federal government, contracting with small businesses is common sense. Small businesses get the revenue they need to create jobs and drive the economy forward, and federal agencies get the creativity, innovation, and technical expertise of small businesses to help accomplish their mission. When small businesses are excluded from federal contracts, agencies, small businesses, taxpayers and the broader economy lose out. For more than half a century, it has been the policy of the Federal government to provide â€Å"maximum practicable opportunity† for small businesses to participate in federal contracts. To achieve this objective, Congress established an aspirational goal in 1978 for the percentage of annual prime contract spending that should be awarded to small businesses each year. Congress later set the government-wide goal at 23% and created a set of sub-goals to support the participation of special segments of the small business community: small disadvantaged businesses (5%), women-owned small businesses (5%), service-disabled-veteran-owned small businesses (3%), and small businesses in Historically Underutilized Business Zones (HUBZones) (3%). These goals help ensure that a diverse set of small businesses share in the jobs and opportunities created by federal contracting. Since 2006, the Federal government has missed the 23% small business contracting goal and all but one of the sub-goals; the 2009 shortfall for the small business goal was more than $4 billion. This gap must be closed. The barriers to entry for small businesses are numerous: weak policies and rules that limit the effectiveness of tools that are supposed to facilitate contracting opportunities; inadequate workforce training to help contracting officers, small business advocates, and program offices understand how to successfully use contracting tools; and a lack of coordination among and accessibility to agency training and outreach events designed to help small businesses navigate the contracting system. Action must be taken to remove these barriers and ensure small businesses get access to federal contracts. A number of important steps have been taken or are underway to remove barriers and open more doors for small businesses in the federal marketplace. †¢ Later this year, the Small Business Administration (SBA) will implement a new rule on contracting with women-owned small businesses. For the first time, contracting officers will have a tool to set aside contracting opportunities for women-owned small businesses in 4 Report on Small Business Federal Contracting Opportunities industries where women are under-represented. This is a critical step toward increasing opportunities for women-owned small businesses. †¢ This year SBA conducted the first comprehensive review of regulations in ten years governing its 8(a) business development program for disadvantaged small businesses to ensure the program’s effectiveness and increase 8(a) firms’ capacity to obtain contracts. †¢ A series of new online training courses have been rolled out (www.sba.gov/training) to walk small business owners through the steps involved in becoming a government contractor. These tools help small businesses navigate the process. †¢ SBA is conducting a comprehensive review of its size standards for small businesses – the first in 25 years – to ensure they accurately reflect the state of each industry. †¢ SBA is working actively to identify and eliminate waste, fraud, and abuse in its business programs through a strengthened certification, eligibility and enforcement process.

Memory Keepers Daughter Essay

Truth be told nobody is normal or perfect each and every one of us have our flaws, insecurities and concerns. In The Memory Keeper’s Daughter by Kim Edwards argues that . In life, there are many things that we can neither cure nor accept nor overcome; sometimes all it takes is one choice to determine the rest of our lives. One winter night in 1964, a Dr. David Henry makes a decision that will haunt his life forever. On a winter night in 1964, an unusual Kentucky blizzard forces Dr. Henry and his nurse Caroline Gill to deliver his own twins for his wife, Norah. First born is the boy, Paul, who is a visibly perfect baby. Shortly after, the baby girl Phoebe is born and is noticed to have symptoms of Down Syndrome. David cannot accept his baby girl because he does not want his wife to go through the same trauma his mother went through with the death of his little sister due to a heart defect. In a split second, David decides that the girl should be placed in an institution to spare Norah the suffering, and he asks the Caroline, the nurse, to take Phoebe to the institution. After Caroline left the Henry’s house, and seeing the horrible conditions of the institution, Caroline decides to keep the baby and raise Phoebe herself. David then lies to his wife and says that their daughter died at birth. This quick lie David Henry tells his family changes their life forever. The â€Å"death† in the family immediately causes a distance between David and Norah; David becomes infatuated with a camera that Norah bought for him while Norah turns to drinking. The distance between the Henry’s continues to grow even further while David and Norah aspire to do totally different things with their lives. David wants to become a photographer and tries to immerse himself in his work, he tries to ignore the resulting toll it takes on his family by viewing everything through a camera lens, almost†¦ We as people are in general very bias even if you don’t mean to be, you can be bias to the types of foods that you prefer, or to people who may or may not have mental illnesses. Life is filled with things beyond our control, and we must rely on ourselves to discover the link between suffering, joy and acceptance. There will always be thing that we can neither cure nor accept nor overcome; sometimes all it is going to take is one choice to determine the rest of our lives and The Memory Keeper’s Daughter by Kim Edwards proves this.

Precis #3 The utterance of untruth is not justified through suppression of doubts on the subject or ignorance of the truth. Taking a statement for what it’s worth, without any further inquiry, is not only doing one’s self harm but also doing harm to anyone who one retells that statement and to society as a whole. In the case of the ship owner, burying his uncertainties about the integrity of his vessel, regardless of its journey’s success, was a wrong. It is also faulty to believe on insufficient evidence or by purposely avoiding investigation. It is asserted that humankind believes blindly because it is afraid of doubt and unmotivated to investigate. One’s beliefs make one strong if one has strong convictions. If these convictions are untrue, however, that strength is stolen and unreal. By this process, it is possible that society could become totally complacent, accepting everything that it is told by whom ever tells it. The process starts at childhood; a mother telling her child what she knows of the world with the child believing everything on the basis of authority. The child has no reason to ask questions of what it is told because it has no reason to first question the validity of its parents. It also has no knowledge of the rules of authority. Some things may be discounted because they cannot be known by a human or by a human of the nature to which one is speaking. If a mother tells her child that its dead dog didn’t feel a thing when it died and that it went up to puppy heaven to be with all its doggie friends, there is immediate cause for the child to discount its mothers story.

So much so that its not even something we tend to give much thought to. Yet in the last decade or two, its silently taken over our working lives. Email alone accounts for a staggering four hours of an average workers day, according to a recent survey by Adobe of more than 4,000 workers across Europe and the US. And thats before theyve even begun to include bids, slide decks, reports, letters, procedures or policies. But how many of those communications engage their audience and get results? And how many damage relationships that then take months to repair (if they ever are)? It only takes a moments thought to realise that few skills are more important today than the ability to communicate well.

Targeting Voters in the Digital Age Research Paper

Targeting Voters in the Digital Age - Research Paper Example Both Obama campaigns of 2008 and 2012 are mirrored images of how voters are targeted in the digital age through social media. A popular opinion is that while the Obama campaign lead because of high interaction with the public and through extensive incorporation of social media and other creative applications, others candidates did not quite manage to adequately engage in dialogue with their voters. The candidates usually go all the way through to make use of the communications technology in the present age to get in the good books of the voters they target which is different from how they used to seek votes in the past age when communications technology and social media were not as powerful as they are now. This research paper basically attempts to scrutinize with the help of research literature how the voters are reached in the digital age, how this digital mania influences campaigns, why the Obama campaigns led over others when delivering their message, and how this whole process i s different from the way campaigns operated some decades before. Like other daily tasks of life are positively influenced by digital technology for example, the ease of depositing bills with our smartphones and listening to the candidates’ speeches online whenever feasible, the political process has also tasted the exciting taste of the digital technology. Both elections of 2008 and 2012 mad extensive use of social media and while â€Å"in 2008, there were about 1.5 million election-related tweets, in 2012 there were 31 million† (Jeffers). It is worth appreciating how through different riveting digital applications the political process is brought into the 21st century and made all the more exciting and comfortable at the same time. The electoral process is made modernized by the digital age and both digital technology companies and political candidates are set out to further modernize this process through employment of latest technologies available. There are many vot ing applications out there in the market presently which allow voters to find the required information about their voters and cast their donations directly to their favorite candidates with one single tap on the touchscreen. According to NYC Votes, voting is a very important ritual and it is their responsibility to bring all facets of the electoral process into the digital age by introducing new applications (Vanhemert). NYC Votes for this purpose has introduced two new applications, mobile web app which is a contribution tool and allows the voters to cast their donations to the candidates and lets the latter collect all donations on their smartphones and Voter Engagement tool which enables voters to find all they want to about the candidates, make donations, and much more. These kinds of things make the political process of elections seem very different to how the candidates reached voters in the past age when nothing was so modernized and all tasks of the electoral process were pa infully time-consuming. Research shows that one of the main reasons Obama presidential campaigns led over those run by Mitt Romney was that people behind the Obama campaigns took the power of digital applications like Facebook and Twitter really seriously and used them to their advantage in any way they could. Social media should not only be considered a change in technology as it is really a change in the public’s tendency to communicate (Jeffers). Research claims that social media was a sure
