...Advantages • The computer can store far more information than a GP. It can draw on a wide variety of sources such as stored knowledge from books, case studies to help in diagnosis and advice on things such as prescriptions / symptoms • The computer does not 'forget' or make mistakes – remembers obscure cases of heart diseases • Data can be kept up-to-date e.g. adding more results of radiology scans / constant updating • The expert system is always available 24 hours a day. • Will never 'retire'. • The system can be used at a distance over a network. Therefore rural areas or even poorer third world countries have access to experts. • Provides accurate predictions with probabilities of all possible problems with more accurate advice especially for obscure illnesses • Some people prefer the privacy of 'talking' to a computer rather than talking to a GP • Gives the doctor more time to deal with other patients / saves overloading doctors in epidemic/pandemic / more time to deal with serious cases • Can provide a second opinion • It can help train young doctors in unfamiliar diseases. • People can do an initial diagnosis from home saving them travel and time costs especially if in a rural area or have long waiting lists to see a GP, e.g. if you suspect your child has a rash you could quickly check the symptoms for meningitis.

...Experiment 1 Determination of the Acetic Acid Content of Vinegar. Goal: During this experiment you will gain experience in working with volumetric glassware, and gain knowledge on how to determine the uncertainties in the volumes delivered by these. In addition, you will use a suitable titration to determine the concentration of acetic (ethanoic) acid in vinegar samples. Objectives: On completion of the laboratory you should be able to: Demonstrate proper techniques for using `pipette, burette and volumetric flask. Assess the random error in the volume delivered from the pipette and a burette. Accurately dilute a sample. Use a suitable titration to determine the concentration of ethanoic acid in vinegar. Theory: All measurements (volumes, lengths, weights etc.) have associated errors. Some, called gross errors, arise from mistakes (writing down the wrong number, recording the wrong units, etc.) but these can be easily avoided by working carefully. Others, called systematic errors, arise from equipment or instruments not operating according to their specifications (for example a pipette delivers 4.96 cm3 rather than the stated 5.00 cm3) or something goes wrong with the measurement procedure (for example there is something unexpected in the sample being studied (called an interferant) that results in the measurement being different from what it would be if the interferant was not there). Systematic errors lead to inaccurate results but can be avoided if the cause...

...the flask was set to the side and the NaOH poured into the top with the assistance of the funnel. When the buret is full, a second Erlenmeyer flask was placed under the buret. The buret was then carefully drained with a person on a stool to carefully examine the meniscus at the top until it successfully met 50 mL. After that was done, the excess base was then disposed of via sink drain. After that process, the acid on the side was set directly underneath the nozzle of the buret with paper towel underneath to prevent rogue spills. A precaution made was to measure out the largest droplets possible to ensure the more accurate results when checking how many droplets were in a milliliter. In contrast to the other method of letting droplets quickly run, it has shown the incorrect method yielded 23 drops per milliliter while the used method listed 11 drops per milliliter. This choice was made knowing that larger droplets will be dropped near the end due to accumulation of liquid when slowly dropping. Prior knowledge of the acid from previous failed attempts gave the call to pour in about half of the base before slowing down the droppage. The base was then stirred with a metal flat piece to disperse the red color. Then slowly was 20 drops added until 3/4ths of the buret was missing. Then it was reduced to 5 drops, 2 drops, and eventually 1 while stirring after each addition. The changes of increments went off lab members’ discretion and judgement based off the longevity of the red blotches...

...(HSCH2CO2NH4) is a compound that can break disulphide bonds. This is because it contains a thiol group (-SH). The thiol group replaces one of the sulphur atoms in the disulphide bond, like this: Keratin-S-S-keratin + 2HS-CH2CO2NH4 --> -HO2CH2CS-SCH2CO2H + 2NH3 + 2HS-keratin When the disulphide bond is broken, the keratin bundles come apart, and hair is weakened. Ammonium thioglycolate is therefore used widely in beauty parlours when customers want their hair re-styled. However, if you use too much of it, or if the reaction is left for too long, you could end up going bald. So do not, ever, try it at home! If you have watched the film Legally Blonde, you'll have seen Reese Witherspoon (acting as a law student) win her first case by her knowledge of the chemistry of perms! 1 How to get your hair re-styled If you'd like your hair curled, it's called a perm. If you like it straightened, that's rebonding. In both cases, the steps are very similar. First, the beautician will wash your hair thoroughly to clean it. Then she applies perm salt (ammonium thioglycolate solution) to it...

...cleverness program that has expert level knowledge about a particular area and knows how to use its knowledge to respond properly. In all aspects the expert systems should replace a human expert. As defined by Edward Feigenbaum, “expert system is a wise computer program that uses knowledge and reading procedures to solve problems that are difficult to require major human expertise for their solutions.” (Robin, 2010) Additionally expert systems are usually considered to have six major components which give detail information about how the system works. It is obvious that expert systems must work behaviorally with system users in assisting them in making better decisions. The system interacts with the user by constantly asking for information until it is ready to make a decision. Once the system has gathered the information needed, an answer is returned to the user. It is important to remember that not only must the system assist in making the decision itself; it must also provide the user with reason it employed to reach its decision. The reading engine processes the date the user inputs to find matches with the knowledge base. The knowledge base is where the expert’s information is deposited. The user interface is what allows the user to communicate with the program. The explanation facility shows the user how each decision is secondary and the systems are only as good as their programming. So if the information in the knowledge base is incorrect or if the reading engine is...

...Management | 1/21/2016 | Project Summary Often knowledge is not shared and unwritten rules drive people’s behavior in another direction. As a way to improve customer satisfaction rating, this project aims at establishing an Electronic Knowledgebase for Healthcare Customer Service Agents (key customer.) The Knowledgebase will be a tool, emphasizing clarity, search ability, and accessibility. The Knowledgebase, will serve both as a platform for research about consumers concerns and as a site for self- development. The knowledge base will be as comprehensive as possible, including presentation materials from all training classes conducted. Rather than simply distributing daily updates, the knowledge base will extend search ability of all updates. In order to make the knowledge base as durable as possible, we will use supported CMS and database platforms. Project Goals & Objectives: * Develop a knowledge base that will enhance hierarchical abilities, and to better utilize the company's individual and aggregate information assets. * Make the Knowledge Base exceedingly useful both as a framework in its own particular right and as an extraneous database * The goal of the designers is to create a user friendly database. * Making the knowledgebase available and usable across the whole organization. Project Greatest Challenge The effective identification and distribution of critical knowledge, does not guarantee its everyday use. What's more, without...

...Acid Rain --------- Acid Rain is caused by pollution containing sulfur dioxide, nitrogen oxide, and ozone ( SOý, NOx, and Oý ) is released into the air. These chemicals are absorbed into clouds and results in Acid Presipitation ( Acid Rain, Acid Snow, Acid Hail, Acid Sleet ). When the chemicals aren't absorbed into clouds, they can drift for miles and fall to the ground, resulting in Acid Deposition, or dry deposition. When Acid Rain falls into water it is mixed in with the normal water and causes the pH of the entire body to be raised. Measurments on the pH ( potential Hydrogen ) scale, rise exponentialy, thus, a lake with a pH of 4 is ten times as acidic as a lake with a pH of 5, and a lake with a pH of 3 is 100 times as acidic, After many rain falls of Acid rain, the pH of a normal lake ( 5.8 ) to 4. Acid Rain has been known to reach the acidicy of pH 2, ( battery acid has a pH if 1 ) this is a drastic change, as normal rain is average pH 5.2. Acid Rain can dissolve limestone and chalk, and corrodes outdoor structures. Statues and monuments that are left unprotected can fall victim to the unpredjudiced destruction of acid rain. Acid Rain reacts to different types of soil and rocks in two ways. 1) Acid rain will dissolve alkaline rocks and soil, or will neutralize the alkalinity. 2) Acid rain will increase the acidicy of already acidic rocks and soil, such as granite...

...primary standards and give two examples. primary standard should fulfill the following requirements: 1) It should be100.00% pure, although 0.01-0.02% impurity is tolerable. 2) It should be stable to drying temperatures, and it should be stable indefinitely at room temperature. The primary standard is always dried before weighing. 3) It should have a high formula weight. A high formula weight will reduce experimental error since a relatively large amount of it will have to be weighed in order to get enough moles to perform the titration and, the relative error in weighing a greater amount of material is smaller than for a small amount. * Potassium hydrogen phthalate (usually called KHP) for standardisation of aqueous base and perchloric acid in acetic acid solutions * Sodium carbonate for standardisation of aqueous acids: hydrochloric, sulfuric...

...with a base. Titration is the process of adding a known amount of a solution of known concentration to a known amount of solution of unknown concentration. The more accurately the concentration of the solution of known concentration is known, the more accurately the concentration of the unknown solution can be determined. Some chemicals can be purchased in a pure form and remain pure over a long period or time. Other chemicals are easily contaminated by the absorption of carbon dioxide or water from the air. Sodium hydroxide absorbs moisture from the air and often appears wet. Thus if a solution of sodium hydroxide is prepared by weighing the sodium hydroxide, the concentration of the solution may not be precisely the intended concentration. Potassium hydrogen phthalate on the other hand, has a lesser tendency to absorb water from the air and when dried will remain dry for a reasonable period of time. Potassium hydrogen phthalate may be purchased in pure form at reasonable cost. Potassium hydrogen phthalate is a primary standard. This means that carefully prepared solutions of known concentration of potassium hydrogen phthalate may be used to determine, by titration, the concentration of another solution such as sodium hydroxide. The equation for the reaction of potassium hydrogen phthalate with sodium hydroxide is: KCO2C6H4CO2H + NaOH ( KCO2C6H4CO2Na + H2O The equivalence point of a titration occurs when chemically equivalent amounts of acid and base are present...
