543 - Essay Example his is because video information is constructed, creative language and regulations, different perception of the same information by different people, fixed values and point of views and organization of video information. In the learning process, students can enhance their academic performances by use of video application. This can take place out of classrooms and even outside the institution. This is more effective way of learning process because of animations, audio, images, and streaming video used in this technology. In this application, it is easy to understand the information or the message in any given topic or subject. Video application also improves retention, when the student is concentrating on watching the video or animation and at the same time reading the message, it create cognitive overload. To prevent cognitive overload, audio should be applied in both video and animations (Clark, 2002). On the hand, when selecting and evaluating video for students in class work, several things should be considered. The video should be suitable for students view, it should be relevant to the topic, and the students should have no visual and hearing problems. It should also have easy vocabularies that are well understood by the students. The use of video has created positive impact to the learning process and improves academic standards in many institutions. Attributes of video include manipulation of time, manipulation of space and animation. Videos can be used to manipulate time by slowing the speed of the video being played (slow motion) or by increasing the video speed. Slowing the video speed or simply slow motion helps in capturing certain aspects of the video that are too fast and cannot be seen clearly by the normal eye. For example, slow motion will enable students see how a fast cheetah runs on camera. Increasing the speed of movement or simply fast forwarding the video helps in eliminating certain aspects of the video that are not necessary to the

Applications of Biochemistry Essay Blood is one of the most important fluids in the human body. It helps carry nutrients such as oxygen to the cells in the body and transports out wastes like carbon dioxide and other metabolites from these cells. Since blood is the medium through which the different organs and tissues in our body communicates, keeping a close eye on the constituents of a blood sample would provide a good indication of the functioning of the human body. Blood gas tests are ordered for patients who might have symptoms of pH imbalance, extreme levels of oxygen/ carbon dioxide, or in order to evaluate the functioning of organs such as the kidneys and the presence of disorders such as diabetes. The latter tests are measured through the analysis of electrolytes and metabolites in the blood. Patients who are on a â€Å"ventilator† in a hospital may have their treatment procedures also monitored using a blood gas analysis test. In the Core Laboratory of University Hospital in London, Ontario, the Gem Premiere 3000 Blood Gas Analyzer is used in order to perform tests on patients. There are two analyzers present in this laboratory. Both machines can run tests for levels of pH, partial pressure of carbon dioxide, partial pressure of oxygen, Na+, K+, Ca++, and hematocrit (Hct). One of the machines however, is also capable of running glucose and lactate tests as well. One other final blood constituent that is also analyzed in this analyzer is for carboxyhemoglobin. If a sample is to be tested for carboxyhemoglobin, the sample must be injected from the syringe into the GEM cuvette. The cuvette is then inserted into another analyzer in order to test carboxyhemoglobin levels. The samples collected for blood gas analysis tests can be arterial, venous, or capillary blood. Reference Range values of measurements in the â€Å"normal range† using the Gem Premiere 3000 (UCSF Medical Center, 2011). All samples are delivered to the laboratory in syringes or capillaries from the bedside of the patient in the hospital. A sample that arrives from the Operation Room can only be stored for and has to be analyzed within 15-20 minutes. Samples that are delivered to the laboratory on ice can be stored for one hour while all other samples must be analyzed within half an hour. Unlike other samples that are analyzed in the lab, these samples are not archived after analysis. All samples must also be warmed between the hands before being analyzed in order to mix the contents thoroughly. All syringes with samples contain a coating of heparin sulfate in order to avoid the clotting of blood samples. Once the source of blood sample (arterial, venous, capillary) has been selected on the display screen of the analyzer, the sample is checked for clots. This is done by testing a drop or two onto a gauze pad. The barcode on the sample syringe is then scanned in order to read the patient ID and store the results. A message then appears on the screen of the analyzer that reads â€Å"Present sample now†. The tip of the syringe can then be inserted at an angle, into the needle that protrudes from the Analyzer. The results will then appear on the screen and be saved on the patient’s profile according to their ID that was scanned. The maintenance conducted on the Gem Premiere 3000 is very minimal. The Gem Premiere 3000 contains a cartridge that has electrodes with all the calibration measurements for the machine. The analyzer is checked daily for printer paper. Every week, quality control tests are run in order to ensure the accurate working of the Gem Premiere 3000. The two control tests administered are the ‘Critical Care QC ContrIL9’ and the ‘GEM critCheck’. The first control tests for the proper analysis of of pH, partial pressure of carbon dioxide, partial pressure of oxygen, Na+, K+ and Ca++, while the second control tests for hematocrit low and normal levels (UCSF Medical Center, 2011). The cartilage with electrodes for calibration measurements expires every three weeks. However, if there is a power cut or an issue with the analyzer, the cartridge must be changed immediately before any other tests are conducted. Once the cartridge has been replaced, it takes half an hour for the cartridge to warm up after the CVP control has been run and before tests can be run again. Once all the tests are run, they are saved on the patient’s profile and are available for access by all physicians and hospital staff throughout the hospital.

Analysis of Shellys Ode to the West Wind :: essays papers

Analysis of Shellys Ode to the West Wind Analysis of Shelly's "Ode to the West Wind" â€Å"Ode to the West Wind† is a poem of deep despair as well as one of vivid imagery. The first section is fairly straightforward with constant references to death, corpses and destruction that Shelly uses as a metaphor for autumn. The allusion to disease and darkness describes the West Wind in this first section. Shelly sees it as a sort of ‘grim reaper’ but seems to come back from the whole topic by also calling it the â€Å"preserver†. In the second section Shelly takes a more lofty perspective in the beginning mentioning heaven and angels and then moves to give a depiction of hell in the last line of the section with â€Å"black rain and fire and hail will burst†. To be a little more precise, the second section is one comparing an oncoming storm to the end of a year. Perhaps Shelly feels that the next year will not be as good as the last and one can even speculate that the west winds are the winds of change or even of evil. I feel that the third section really supports the theory that Shelly did portray the west wind as the bringer of evil. The wind is described to be awakened from a place of peace and beauty. The line â€Å"Thy voice, and suddenly grow grey with fear† seems to describe a sense of darkness and loathing, a chilling feeling flowing through the veins. The west wind is power. The fourth section plays on the feeling that this wind is all-powerful and Shelly seems to give the impression of bowing down before it. Impulses, uncontrollable, tame-less are all words used to describe the wind in this section. In almost a begging tone the speaker of the poem asks to be taken away from his pain as said â€Å"Oh! Lift me as a wave, a leaf, a cloud! / I fall upon the thorns of life! I bleed!†. Going back in the poem though the west wind seems to have created this and the speaker loathes it, but here shows he also still needs it. The final section seems to come to terms with the west wind. The asking for music even though the leaves are gone and there is not to celebrate shows this perspective: I will still play but it will be one of sadness.

When Harry Met Sally Essay -- essays papers

When Harry Met Sally The film I chose to view for this Romantic Comedy paper was When Harry met Sally. I enjoyed this movie. The two main characters were Harry (Billy Crystal) and Sally Allbright (Meg Ryan). When first introduced to these characters, Sally is driving to New York, and Harry, who is the boyfriend of Sally's friend, is catching a ride with her. Sally is a very structured person. To quote Harry, she is a "high maintenance" women. Harry, on the other hand, has a more laid back attitude. This causes some tension between them on the long drive to New York. This fits well into the romantic comedy genre. In a romantic comedy there is usually tension between the two charcters in the beginning. Part of this pattern is for them to soften toward one another and by the end they fall in love. On the way to New York, Harry tells Sally some things about men she doesn't know and is reluctant to believe. One thing he tells her is "men and women can't be friends because sex gets in the way." This only increases the tension between them. By the time they reach New York, Sally doesn't appear too happy with him. She seems angry with him, but anger is sometimes used to cover other feeling. This is also a classic feeling in the genre. A gap of several years passes before they see each other again. They see each other at the airport, but they both pretend not to know the other. The next time they meet is a couple of years after they saw each other at the airpo...

Free Term Paper Sample Nuclear power has been used in desalting plants. As a precedent for such an idea there are combination steam-electric and water-conversion plants such as that operating on the island of Aruba in the West Indies. Here the by-product heat from a power plant is used to desalt the island's drinking water. The first nuclear-powered desalination plant was built by the United States at its military base at McMurdo Sound in the Antarctic. This is a small unit, producing 14,400 gallons of fresh water daily, and not economically competitive with conventionally fueled distillation plants. However, since it is very costly to import fuel to this distant base, the nuclear desalting plant was judged to be advisable. Experts feel that to compete with coal, oil, or gas, nuclear power must produce at least 50 megawatts of power and ten million gallons of fresh water a day. Russia seems to have a lead on the United States in the field of large nuclear desalination plants. In the city of Shevchenko on the and east shore of the Caspian Sea, there is a conventional power-plant-desalination combination supplying 1 1/2 million gallons of fresh water a day. The Russians have immediate plans for another desalination plant at Shevchenko, this one to be supplied with heat from a nuclear power plant. Our country is planning for such nuclear combination plants by the middle of the next decade. In March 1964, the Office of Science and Technology reported the findings of its study of large nuclear-powered desalination plants. Suggested as feasible by 1975 were installations producing from 1000 to 1500 megawatts of power and from 500 to 800 million gallons of water per day. Fresh water would be produced at a cost of less than $0.30 per 1000 gallons. Sites suggested for these giant dual-purpose nuclear-energy plants were Southern California, Arizona, the Gulf Coast, a nd the New York City area. The firm of Atomics International has proposed a combination nuclear power plant and desalination plant for erection in California. This sodium graphite reactor would produce 400,000 kilowatts of electricity and 50 million gallons of byproduct fresh water daily at a cost of only $0.26 per 1000 gallons. On a shorter-range basis, a joint committee of the Metropolitan Water District of Southern California, the Atomic Energy Commission, and the Department of the Interior began investigation of smaller plants producing between 5 and 100 million gallons of fresh water a day and from 150 to 750 megawatts of electricity. These smaller plants are foreseen as early as 1970.

How to win more work with your bids and tenders

How to win more work with your bids and tenders 9 ways to win more work with your bids and tenders In sport, there’s often a fine line between being hailed as the champ or dubbed an also-ran. For every Olympic 10,000m gold medallist there were probably dozens of potential champions. But no matter. Whoever crosses the line first, even by a fraction of a second, takes the spoils. Coming out on top is often about good preparation and the little things your competitors failed to take into account. It’s the same when bidding for work. And you probably know from experience that the competition to edge ahead can be as fierce there as on the race track. So here are nine ways you can get your nose in front to consistently be the champ, and not end up an also-ran chump. 1. Write fewer bids Ironically, it’s sometimes easier to win more work by focusing your energies on fewer bids and tenders. Alarm bells should be ringing if you find yourself winging it when answering half a dozen key questions in an invitation to tender (ITT) or pre-qualification questionnaire (PQQ). Newcomers, especially, can be tempted to bid for contracts that don’t actually suit their capabilities. So concentrate on the bids and tenders where you are most likely to succeed. 2. Get under their skin †¦ †¦ in a good way, of course. When you do identify a suitable opportunity, ask yourself this crucial question: how can I find out what the potential client really wants? Sometimes it’s obvious. A good ITT will make their priorities clear from the outset. Sadly, the reality is that most are poorly written. For example, you may need to read carefully to spot key needs that aren’t even mentioned in a list of ‘essential requirements’. In any case, always broaden your research beyond the ITT to get the bigger picture of what matters to them right now. Check out their website, news stories about them and blog posts by the CEO. And if you are looking to renew ongoing business with a customer, speak to your sales team or client relationship managers. They’re best placed to give you crucial insights into the challenges the client faces, or their preferred method of working. 3. Put your win themes in the spotlight Once you understand your potential client, focus on the factors most likely to win you their business – your ‘win themes’. For example, your prospect might be an eco-friendly organic food producer looking for a supplier of cardboard packaging. Your win theme here may be that you source all your cardboard products via certified sustainable forest management. Use every relevant opportunity to drive home that message, such as in the executive summary, case studies and even in project team CVs. It’s vital to back up win themes with facts, though. In the case above, this might be how many trees you’ve had planted, or how you helped another client achieve their carbon emissions target six months early. 4. Remember it’s not about you Win themes are firmly focused on the client’s needs. And your entire bid or tender should be, too. It’s easy to come out all guns blazing, singing the praises of your own organisation – but doing thats likely to just alienate the reader. Far better to make it clear, early on, that you understand their issues and needs. And when referring to the features of your product or service, make clear the benefits for that particular client at the same time. So, avoid the old-school, in-your-face sales pitch approach. And adopting the right tone can be crucially important in other ways, too. 5. Keep it positive A delegate on one of our bid-writing courses couldn’t understand why so many of their submissions for event-management contracts met with only a lukewarm response, and ultimately a rejection. He told us: ‘We know we can match our competitors on price. We have masses of experience, too, and plenty of good case studies to back us up.’ A review of their ITT responses revealed the root of the problem – a worryingly negative vibe. Statements such as ‘We believe we can deliver the contract to a satisfactory standard’ were unlikely to inspire confidence. Better to use positive phrases such as ‘We will ensure that †¦Ã¢â‚¬â„¢ and a stronger adjective than a mere satisfactory. Likewise, they referred to ‘trying to’ or ‘aiming to’ achieve goals, rather than saying there were ‘confident’ of doing so. And when describing a prospective client, avoid being overly deferential in a way that is likely to make them cringe (‘We would be honoured to build a relationship with your prestigious research establishment ’). It can sound like you feel lucky to even be in with a chance of working with them. They’re going to be putting their trust in you. So its far better to position yourself as an equal or high-level adviser. Remember, too, that referring to competitors is generally frowned upon in bid writing as much as in other areas of sales, and with good reason. For one thing, your response should be strong enough to sell itself, without taking potshots at the opposition. (Plus, do you really want to give over valuable space in your bid to name-checking alternative suppliers?) 6. Favour simple over waffle It can be tempting to include everything you can think of when responding to a question in an ITT, in the vain hope that your singularly comprehensive answer will impress the reader. That’s rarely the best idea. Let’s look at two potential responses from a reader’s point of view. Question: ‘What are your proposed delivery timescales?’ Answer 1: ‘Four months.’ Answer 2: ‘Given the emphasis you have placed on achieving your ambitions within a relatively short timeframe, we have carried out an in-depth assessment of the global effects of leveraging the synergies we can achieve through our involvement in this project. This substantive evaluation has given us the confidence to predict a delivery period of 16 weeks, in line with your expectations.’ The first answer is straightforward and its lack of waffle makes the writer sound more confident. Only give detail that’s helpful to the reader, using clear, concise language that avoids unnecessary jargon. Remember, though, that it can sometimes help to mirror some of the language the prospective client appears comfortable with – they may refer to ‘service users’ rather than ‘customers’, for example. In which case, you should too. 7. Help them to help you Where the bidding process allows it, do communicate with prospective clients. It can help you build a rapport with them. And don’t be afraid to seek clarification on important points, such as budget. Doing so, far from being a sign of weakness, will show your dedication to genuinely fulfilling their needs. It will also give you a chance to build your working relationship even before they hire you. (Note though that in formal tender processes, both questions and responses from the client may well be made public to all suppliers tendering.) 8. Beware of ‘the stupids’ Your submission is finished ahead of the deadline. You’ve even double-checked it against a compliance matrix to make sure you’ve included a solution for everything the ITT asked for. Almost time then to breathe a sigh of relief and get on with all those everyday tasks you’ve had to put off. But not so fast. It’s so easy to blow it in the final stages. First, watch out for silly mistakes that undermine your credibility. Years ago, we were working closely with a key decision-maker whose role at the time was to award contracts to run entire rail franchises. As you can imagine, such decisions are far from simple and involve assessing a huge amount of technical detail. Yet he told us that his first action when assessing any bid was to quickly leaf through it and circle silly mistakes, which he called the ‘stupids’. These could include, say, instances where the writer had made a common spelling mistake in the name of a station. (For example, writing ‘Bridgewater’ instead of ‘Bridgwater’, when referring to the town in Somerset, UK.) Though these might seem trivial, collectively they call into question just how well the supplier knows the area. He and his colleagues would take the total number of silly mistakes into account when weighing up competing bids. In fact, his non-orthodox technique has a sound basis in social psychology. That’s because we are all hard-wired to look for cues that suggest we would be wise not to put all our trust in what we’re reading. The cues we rely on most (even if we do so unconsciously) include those that are easy for the people we’re assessing to get wrong if they don’t know what they’re doing. Failing to spell key place names correctly is a good example. The impact of stupids may be far greater than you think, as they can lead decision-makers to quickly lose confidence in your document and, by default, you and your organisation. So, ensure your document has been edited carefully and then proofread properly. Pay particularly close attention to the executive summary – a stupid mistake there really can make all the hard work of putting a bid together utterly futile. 9. Don’t fall at the final hurdle Finally, presentation. It’s more important than you may think. Your document needs to look approachable and professional – and be sure to check for any specific requirements such as the number of copies they need and whether the bid or proposal should be bound. And if you submit your bid electronically, do make sure it’s been safely received. After all, it’s impossible to win a new piece of business if you actually fail to deliver your bid at all. Try these 9 steps to finish first Its a competitive world out there, and in sales – unlike in sport – theres no prize for coming second. But apply these nine steps to all your bids and tenders, and you will be odds-on for a win every time. hbspt.cta.load(2645537, 'bcc87e53-f3f4-4632-9e9d-ecd393514f70', {}); Image credit: Halfpoint / Shutterstock
