Color Blindness Essay examples -- essays research papers fc

Color Blindless     Color blindness is the inability to distinguish particular chromas. Itis generally an inherited trait, but can core from a chemical imbalance or eyeinjury.     There are three primary colors. They are red, blue, and yellow. Allother colors are the results of diametric combinations of primary colors.Special visual cells, called c anes, are respon-sible for our ability to seecolor. plenty with normal vision have three different types of cones, eachresponsible for a different primary color.     The absence of particular cones causes the absence of particular colors.This can be one cause of color blindness. There are four types of colorblindness. The rarest forms are mono-chromatism and a-typical monochromatism.People with monochromatic vision, or total color blindness, has no cones at all.As a result, they have no ability to see colors, and no hue discrimi-nationwhatsoever. Monochromatic vision is very similar to watching a black and whitetelevision program.     Somebody with a-typical monochromatic vision has just one type of cone,and can see just one color, and various shades of that color. This form is evenrarer than the "typical" monochro-matism.     Another, more common, form of color blindness is called dichromatism.People with di-chromatic vision tend to confuse red, green, and gray, but caneasil...

Bullet Busters :: essays research papers

On Wednesday, the 13th of March 1991, Ameri set up Cablevision of Queens, NewYork, sent the graduation electronic "Bullet". This so-called "Bullet" was infact, an electronic signal directed to unauthorized overseas telegram boxes causingthem to turn-off. Approximately 300+ unsuspecting customers accordingly called thecable company to complain and were subsequently taken to court for cabletheft.The "Bullet" works by ordering the computer processor within the cable boxto lock-up if it is authorized for all channels. Since pirate chipsinstalled in a cable box would authorize all channels, the TV "goes black".HOW THE CABLE COMPANIES CATCH PIRATES on that point are several methods here are some of the more popular. The firstmethod is somewhat costly to the cable company, and is used usually exclusively whenwhen they theorise they have a thief. A device called a Time-DomainReflectometer(TDR) is used to send a timed signal from the cable lineoutside yo u home to your decoder.The reflected cypher of the signal is measured and then compared toprevious measurements to find a time difference which would indicate thatthe box has been tampered with. Pirates were able to get around this by position an in-line amplifier which would weaken the reflected signal.One problem with TDR is that you need previous readings, which are notusually taken at the time of installation for a reference point.The befriend way is to modulate an identification signal onto the cable lineat about 108 MHz. This signal sounds something like a "cuckoo", and "leaks"from the converter box where it can be picked up by cable company employeesoutside of suspected pirates homes using hand held receivers. Unfortunatelythe signals sent by the cable companies can to a fault cause interference with FMreception within the home.A third method is to program all cable boxes from the headend to display amessage. This message is displayed only by boxes which hav e had a test chipinstalled and left in. The message informs the customer that they have wona free t-shirt or something similar. They only have to go to the CableCompany HQ to pick up their prize. And what a prize it is A FREE trip tojail Dont fall for this. at that place is no free lunch.IS THERE A FIX FOR THE BULLET?Yes, there are several solutions to the problem. The "Bullet" as sent fromheadend causes the box to lock-up, and not widening a picture. The fix issimple - unplug the power cord. After a few minutes, plug-in the box againand it should reset. At worst, the box may stay deathly for up to 24 hours.

My Big Sister :: College Admissions Essays

My Big Sister   She was so concentrated on her task that at first she did not come across the quiet voice behind her. In one hand she held an enormous clear plastic bag, and with the other she was picking scarves off a display crucify and haphazardly stuffing them into the bag. She worked quickly because after an hour in the town hall, she was ready to head home. An hour of speeches read in a passionate laggard had left her feeling a strange apathy.   She usually enjoyed the annual Homeless Vigil, and had worked very hard to collect the hats and scarves she now treated with such indifference. Standing unsocial on the now empty stage and gazing out into the rows of decaying wooden chairs, she tried to imagine the people her work would help, but found she didnt really care. All she could hypothesize about was getting out of that old building and going somewhere with central heating.   With a sudden clarity, she realized that she didnt want to be a crack of this farc e anymore. What did it mean if a few middle class families got together once a year to be preached at by a band of tired social service workers? They listened patiently for an hour, then donated a few bucks to assuage their consciences. They drove home in their foreign cars to their nice two narrative houses and ate a hot meal, confident that they had paid their dues to humanity. If they could be so easily satisfied, so could she.   Excuse me, maam? Finally the voice got her attention, and she turned around. The microscopical voice belonged to an equally small boy shifting nervously from foot to foot.   What is it, Hon? she managed a tired smile.   I heard your speech tonight, about all those kids who dont arrive at anywhere to live. You said that you were collecting clothes and stuff to keep them warm.   Thats right. This time of year it is especially hard for them.

Competitive Analysis - Car Wash Industry Essay -- Business Analysis

IntroductionThe task of this assignment is to complete a competitive analysis of 2 of the largest competitors in the industry of chosen study. This researchers chosen field is the Car wash off industry. Unlike many industries, the Car Wash industry does non have dominant players or franchise names that rule crossways the country. Unlike other automobile related industries such as oil replace (Rapid Oil Change), tires and batteries (Goodyear), and auto parts retailers (NAPA), where these types of name players may have thousands of locations throughout the country, there are no big name players in the Car Wash industry. Although there are companies that own and operate multiple car wash facilities, most of these multi-location owners operate multiple locations throughout a metropolitan or regional area and their overall location totals are nominal. Since there is a lack of dominant competitors to analyze, this researcher will focus on an analysis between the dickens main cat egories of car wash ownership full service vs. unattended operations. Industry Overview and DescriptionThe Car Wash industry began to start and grow across the U.S. after the conclusion of World War II. Americas economic rebirth and prosperity created a boom in the housing and automobile industry. What began as a business to satisfy Americans love of the automobile has grown over the past several decades into an international industry. From slipstream ones car in the driveway with a water hose and bucket of soapy water, to the do-it-yourself, unattended coin operated high-pressure wand locations, to todays professional car washing businesses which feature complex automatic equipment and technological systems to wash cars more safely and effectively than ... ...ion wash bays are a huge competitive risk as these gas retailers usually offer discounted car washes with the purchase of gasoline.For the full-service wash precedent, they too have to be in tune with cheaper and less se rvice options as in challenging economies, their services become more difficult to justify for the consumer who is worried about income. Competitive rivalry, threat of substitution, and threat of overbold entry are the forces that the full-service model is at most risk with. Poor service reputation and lack of a strong value proposition puts this car wash model at serious risk of substitution. The treat of new entry for both business models can be significant as there are many new innovations in car wash businesses such as mobile wash stations and new and used car dealerships that are adding this business in what has been a very difficult car economy.

Poor Black Little Fellow

CAUSE AND EFFECT ESSAY. THESIS STATEMENT The Pembertons neglect Arnies basic unavoidably for various reasons. All along years, white people look at been discriminating black ones. That is why several black people, such as Martin Luther King, have been bit for their right to be treated as equal to any other person of any other race. And even though white people have been simulating to accept them, they have been treated as if they were of a lower social class.This is what happens with the main character of the short story entitled Poor Little dingy Fellow by Langston Hughes, Arnie, who was adopted by The Pembertons, a white family. They neglected Arnies basic need for various reasons. The first reason why they cut back Arnies necessities is that they were used to live by their own. They had spent their marriage on loneliness. This is because they were unable to have children. And hence, they became accustomed to live alone.As a result, they were incapable to take sympathize with of Arnies affective needs. For instance, they let him sleep in the garage and they allowed him to bring friends but not inside the house. All in all, these features are important to call forth that The Pembertons avoided Arnies needs. The second reason why The Pembertons paid no attention to Arnies requirements is that he did not belong to their family. He was son of The Pembertons pin-up servants who had died and to whom The Pembertons loved very much. Therefore, they adopted Arnie as their own.Nonetheless, they were unable to completely accept him and consequently, they had many prejudices against him. On the whole, these pieces of information contribute to state that The Pembertons took no mark of Arnies necessities. Finally, the fact that Arnie belonged to an Afro-Ameri nooky culture is the last reasons for The Pembertons carelessness. As he was black, The Pembertonss deep inside had prejudices against him. Apart from that, they adopted him just because they felt it was their religious duty.And as a consequence, even though it was unintended, they behaved in a rude way towards him. All things considered are significant to assure that Arnies needs were ignored by The Pembertonss. To sum up, the fact that The Pemberton lived alone their whole life, that Arnie was not their son and that he was black contribute to the reasons why the family uncared for Arnies affective needs. Summarizing, taking into account these facts it can be affirmed that there were many causes why The Pembertons avoided Arnies affective requirements.

Organizational Culture of Cisco Systems Inc. Essay

Cisco Systems, Inc. is a global family that embodies the many characteristics of a company that set its employees as much as its clients. Cisco listens to their employees and responds to their needs. Cisco Systems has long been recognized as being one of the top 25 best places to work in America because of how its high regard for its employees.Ciscos Organizational AppealThe appeal of Ciscos organisational culture is that it appreciates its employees. It offers flexibility that few other companies do. This is particularly appealing to me in that I have observed over the years that many companies forget that if an employee feels like a stakeholder in the business, then he or she will be far more willing to take the extra steps to walk the extra mile to perform to the highest of standards. An unhappy, disgruntled employee, on the other hand, will merely show up, do just enough to keep the boss off his or her back and call it a day. Cisco Systems offers a myriad of perks to its empl oyees including but not limited to1.Access to on-site childcargon.2.E-learning courses.3.Formal and in-formal flexibility of work hours that allows for the integration of home and professional life in a comfortable, manageable way.4.On-site lean Watchers Programs.5.Elder Care Assistance.These are but a few of the benefits that Cisco offers. When an employee feels like the company believes in and cares for them as a person, then they believe in that company too.I share the core value of employees coming first with Cisco. I believe that without employees to tote the barge and life the bale, the work will not be done. All too many companies forget that business is like an upside-down pyramid and that the employees are at the top of the pyramid no matter how commission may try to think otherwise.The seven characteristics that Cisco Systems employees include stability where ingathering comes in a balanced manner, outcome orientation, innovation, team orientation, people orientation, o rganizational easygoingness and detail orientation. Each and every one of these characteristics must be present. They must be present in a manner that is balanced. Should any one of them characteristics come imbalanced, an organization will find itself in deep trouble. Cisco Systems has managed to find and maintain the delicate balance of all of these and their success is reflected in their continued growth and prosperity.However, if I had to narrow the field to just one, I would have to saw their orientation to the team concept, team organization, if you will, is their primary embodiment. Virtually all of their professional activities are organized around partners and teams.Cisco Systems possesses a very strong cultural appeal. This is evidenced by the undeniable fact that they are a leader in cultural diversity and technological advancement. They have earned the respect of their employees and their partners because of this organizational culture. This culture is ethical in nature because to treat employees fairly and as humans beings, not just bodies that fill the seats in the cubicles is a matter of morality on the part of the employer. High business morals are tenacious with high business ethics.It cannot be denied that Cisco Systems is a model for other organizations to emulate when the layers are peeled away.ReferencesGildorf, Jeanette W.

Favorite Brand Paper Essay

Within this paper the reader will read about 3 to 4 companies the author would like to work for with detailed explanations as to why. Furthermore, the reader will learn ways of engaging those companies in the most effective manner in communication that guarantees the authors credenza of those position(s), and what makes the author possiblely valu fit to those companies. In ill-considered, YOU the reader will learn the, who, what, and why of piecing a proposal (an face lift huckster) together while keeping it short and simple. The elevator pitch that will be used depends on what position you would like to expose oneself to within/for the organization. For now, let us check out potential companies the author envisions himself working for. Then we can look a few elevator pitches that will guarantee the authors acceptance.Ideal Company(s) to Work For/WithOne of the authors ideal bon ton(s) to work with would be in the area of market advertising. Reason being is that the author has a sincere belief that influence plays a major(ip) role in economic growth and development if not the opposite depending on what is being promoted. So the ideal company would be a company called LGA (http//lgaadv.com/). Another interest is management for a company therefore, the ideal company the author would like to work with is Integrated Management Associates (http//www.ima-pm.com/) who specializes in developing lead skills from self capture-to-company capture perspectives. Finally, trading/negotiating is another interest the author admires. So sales would be an ideal career and likes Wal-Mart (http//www.walmart.com/).Does He Got What It TakesThe author has somewhat an have got related background in those fields. For an example The author as a young man handled voluminous orders and door-to-door sales for a direct marketing company (he wishes to not mention the name). His aggressive persistence and way with words ushered him straight to the top. Moreover, his desire to work wi th others in his interest in trading (in which he was exceptional at) gave a desire to work with like minded individuals- so obtaining a degree in the services of Management enabled the author to learn skills in communication, observation, integration, coordinating, and specialization. Although the author doesnt remember what was said that placed him in positions of power in recent years, but since developed, let us look at his elevator pitch in obtaining a career of his dreams on a macro-level. To get a bit more creative, he would choose to be President of THE united STATES of AMERICA.An Elevator PitchThe elevator pitch that will be used to explain the authors value to those companies is as expressed below for the local companies and the position for a seat as president also. The pitch is as so Hello, my name is Brandon White, also known as BWU. I will be obtaining a degree in business management with a concentration in management and have recently graduated from the University o f Phoenix. I am face to add value to your company/constituents with learned skills I have developed over decades. I recently written an article revealing the phenomena. Can I invite you to my summit to elicit your inquires? The pitch, does it sound as if it is coming from someone who wants to simply work and stay at the bottom of the totem poll? The author surely doesnt think so, however, the pitch does reveal a drive to reveal something that is only possessed by the deliverer. The author basically states that developing a pitch that entails/projects confidence, influence, and room to give the listener room to ask questions wins if responses are in harmony with the observers question(s).Best Ways to Make Contact fit to the author, best ways to make contact would be in the most effective form of communication- writing. He writes that because the communication would be void of all emotions as oppose to speaking over a telephone or in person and listening to reactions stemming from e motions.And the same would be applied for those needed to contact that whitethorn have influence in the hiring process. Granted, the author isnt saying create something so influencing that doors will be opened for you, but injecting assorted levels of communication for different levels of positions. For example, if you wanted to land a gig working within a company your communication would reflect an ability to work well with others, being able to follow directions, and having some form of dependability. However, if you wanted to land a gig running a company, one must know how to nurture that company to the hitch all the above answers for working that company would be included while being able to communicate and execute thoseactions.

Counting cells using the pour plate method Essay

In the start of this assignment, I was told to choose one of seven some other experiments to do. I chose the Counting cells development the pour cuticle method because I find it much easier than the other ones. In addition, I yield had past experience therefore it should be straightforward. I also let much knowledge of it than the other experiments. I will be testing the effects of various items on the growth of bacteria. I will investigate using the pour plate method in which I will be counting the cells of bacteria produced, of which ar vi adapted.The pour plate method discount be use to establish the get of microbes/mL or microbes/gram in a smack. It has the benefit of not exact need of earlier arranged plate, and is unremarkably used to examine bacterial contamination of foodstuffs. While using the pour plate method, a diluted specimen is pipetted in a sterile Petri plate, and succeeding(a) melted agar is tipped in and combined with the specimen. Using this techniqu e permits for a bigger volume of the diluted specimen. This is normally in the choice of 0. 1 1. 0ml. This technique yields colonies, which produce colonies all over the agar, not provided on the surface.Caution has to be taken with this technique to guarantee that the organism to be counted is able to resist the temperatures linked with the melted agar. Dilution Factor The dilution factor is a bout used for getting the whole number of infected cells from the observed data. Microorganisms are commonly counted in the laboratory using methods like the viable plate count, where a dilution of a stress is plated onto an agar medium. Following the incubation, plates with 30-300 colonies per standard-sized plate are counted.This number of colonies was selected because the number counted is high enough to have statistical accuracy, so far low enough to vitiate nutrient competition among the developing colonies. Each of the colonies is supposed to have arisen from only one cell, but th is may not be true if chains, pairs, or groups of cells are not entirely broken apart before plating. The sample has to be controlled so that it consists of a number of cells in the right range for plating. If the cell number is high, the sample is diluted but if too low, the sample is concentrated.Dilutions are carried out by sleepless, unfertile pipetting of a known volume of sample into a known volume of sterile water, buffer, or saline. This is mixed well and wad be used for plating or further dilutions. If the number of cells is unknown, then a range of dilutions is usually ready and plated. HYPOTHESIS I predict that the more the dilution is, the lesser the number of colonies. VARIABLES I have considered the accuracy of my prizements and come to the conclusion hat the dependent variable is the aseptic technique, which in this case was E. coli.This is because I had to measure how much I had to put into each of the sterile distilled water bottles. I did not have to restrain many measurements but other than measuring, the E. coli and a sample of dilution into the next solution then transfer 1. 0cm3 into the petri dish. Obviously, other events took place among these measurements. The independent variable was the Pasteur pipettes which I had to go for changing e really time I used one so that my solutions will not get contaminated. My variables are continuous. This means that each time I done the experiment I had to do the equal thing over again, therefore they are continuous.APPARATUS Six universal bottles, or capped containers each containing 9. 0cm3 of sterile, distilled water Twelve sterile Pasteur pipettes plugged with like wool 1cm3 plastic spray, fitted with a silicon rubber connector, to attach to Pasteur pipettes Six sterile Petri dishes Suitable culture for counting, e. g. E. coli or sample of pasteurised milk deliver of suitable agar medium, molten, kept in water bath at 45i C Bunsen burner China graph pencil or spirit crisscross pen D iscard jar containing disinfectant Incubator at 30i C Adhesive tape Alcohol.Ruler The unlike items must be the same amount as each other and these measurements must be accurate due to incorrect results. To make sure my results are reliable I will make sure I count the cells of bacteria twice so I know if I have made any errors. HEALTH AND SAFETY break out protective clothing (gloves) Wear eye protection (safety glasses) Tie hair up Make sure you dont throw the plastic syringe and sharpened pencil near due to people being stabbed by a pencil Make sure hands are washed before and after the experiment, well with soap and water.Working area must be clean during work Must be aware of contamination Everything must be labeled correctly due to confusion and a mix up in solutions Industrial Methylated Spirit is highly flammable to be careful If the alcohol in the beaker catches on fire, cover the beaker with a damp cloth PROBLEMS WITH PLATE COUNTS They need long incubation for colonies to even show When cell clump, they can guide to an error in counting the viable cells It is extremely simple to have too less or too many colonies on a plate to precisely measure viable count.Avoidance of squashing usually involves serial dilution TO AVOID CONTAMINATION OR OTHER PROBLEMS Wash hands with soap thoroughly before and after experiment Disinfect table before and after experiment Ensure lid of the plate is not took off completely Do not even put the lid on the table so other bacteria does not get onto plate Do not cough up or sneeze on the plates Work near bunsen burner METHOD Set up equipment. Label containers of sterile distilled water 10-1, 10-2, 10-3, 10-4, 10-5 and 10-6 and the Petri dishes similarly. Label the Petri dishes on their bases. call down the sample thoroughly to ensure that it is evenly mixed. Then using aseptic technique, transfer 1. 0cm3 of the container labeled 10-1, using the sterile pipette. After use, place the pipette into the thresh about jar of di sinfectant. Mix this first dilution carefully then. Using a fresh sterile pipette each time, transfer a 1. 0cm3 sample of each dilution separately to each appropriate, labelled Petri dish. Again, using aseptic technique, carefully pour cooled, but molten, sterile agar medium into each Petri dish. Swirl each Petri dish very carefully to ensure that the samples and the agar are evenly mixed.Gently move each dish in a figure of eight pattern, but do not allow the agar to spill over the edge of the dishes. Allow the agar to set, and then fasten each lid with 2 pieces of adhesive tape. lift the dishes, and incubate at 30i C. After incubation, count the number of colonies place in a dish containing a suitable dilution. Calculate the number of viable cells present in 1. 0cm3 of the original culture. As an alternative to pipetting a 1. 0cm3 sample into each Petri dish and then adding molten medium, a 0. 1cm3 sample may be transferred to a ready poured agar plate.The sample is then spread uniformly over the surface of the agar medium using an alcohol flammed glass spreader. 1. 2. 3. 4. Following a couple of days, various sorts of microbes grow as divided colonies. Cells from separate colonies could be picked up for a subculture. IMPLEMENTING This was a very quick process in which everything had to be complete straight after another. Therefore, measurements also should have been done quickly during the experiment straight away to put into whichever solution it may have been. My results have been recorded according to how much attempts I made.In each attempt, I have shown the dilution factor and how many cells I saw in each square using the see through round scale. The see through round scale had 64 squares in it. Some squares were completely filled therefore I have written that down too. I done three replicate to ensure my results were accurate.10-6 1422 320 1088 943. 3 My results show that as the dilution factor increases the amount of colonies decrease, as utter in my hypothesis. The decrease is shown as exponential, also there no peaks. According to my results, the values are quite variable, but as predicted. The maximum value in average is at the 10-1 dilution factor, 10688 and the minimum value in average is at the 10-6 dilution factor, 943. 3. Here are my results shown on a line graph ANALYSING CONCLUSIONS My hypothesis declared that the more the dilution factor would be, the lesser the number of colonies.Well, according to my results, I was correct. As my dilutions increase, my colonies decrease. This is because, during the experiment when I had to take out 1cm3 of solution from 10-2 and put it into the next, which was 10-3, the E. coli was being shared, and decreased as it was let out through the syringe. When I poured it into 10-3, I had to shake it so it was mixed properly. Subsequently, I did the same again but to the next aseptic technique, which was 10-4. Again, the E. coli was being shared. Obviously, it was lesser than it was in 10-2 because it was also being shared in 10-3 and 10-2.This is why as the dilution factor raises, the colonies fall. ANOMALOUS RESULTS As shown by my results, I only had one error. This was in my third attempt of the experiment at dilution 10-5. It may have been due to contamination while carrying out that particular part of the experiment. For example, I may have left the lid of the plate on the table, which could have not been disinfected, therefore it picked up other bacteria. Alternatively, it could have just been due to my morbific flu, I probably sneezed unintentionally on the plate, which caused the whole plate to be filled with colonies.Other reasons include my hands being dirty. Next time I will make sure I wear gloves, or I sneeze to the side if I do and I ensure that I keep the desk disinfected encase I by chance leave the plates lid n the table. However since there was only one error, I do not think it made a huge difference to the experiment since my prediction was still correct. But next time I will be aware of these little mistakes. EVALUATION I think my results were reliable since I just made one error and did not have any other anomalies.However, i think if I was to do the experiment, again, I would improve on avoiding contamination and I would do more replicates to show my results as more reliable. My results do not have a specific trend or pattern in which they decrease in, but the fact that they do not keep change magnitude and decreasing shows its reliability. My replicate values are not very close together therefore tell I should have done more replicates for accuracy. I think I may have made parallax errors when counting the cells. This means I may have miscounted the results or over counted them.This may have been because of my problematic eyesight or due to distraction while counting. This could have been improved to accuracy if I counted each plate 3 times at least. So the correct amount of colonies in each plate would be certai n and not doubted on. On the other hand, I could have used a different method to count the cells to make it easier for me, like using a counting meter. To achieve much accurate results I think, other than avoiding contamination, I could have changed around my method a little so it could have been done quicker or much accurately.For example, I could have just left the petri dishes in the incubator for a little longer or lesser period I could have also used a different culture for counting. If I were to do the experiment again, I would repeat it more than just 3 times so my results can show more accuracy and I can rank where/when I went wrong. Furthermore, the next time I would limit the temperature to see if that would make a difference in allowing my results to be precise and I would also avoid causing any errors.BIBLIOGRAPHY http//www. bio. fsu. edu/courses/mcb4403L/dilution. pdf http//filebox. vt. edu/users/chagedor/biol_4684/Methods/platecounts.html http//biology. clc. uc. edu/f ankhauser/Labs/Microbiology/Meat_Milk/Pour_Plate. htm http//www. microbiologyprocedure. com/microbiological-methods/pour-plate-method. htm Class notes Class hand outs http//www. mansfield. ohio-state. edu/sabedon/biol4038. htm.Micro Organisms and Biotechnology, John adds.
