Steve Wozniak essays

Steve Wozniak essays At first I had began brainstorming trying to think of a subject for this paper. I had heard Mr. Perry speak of Apple computer and of Steve jobs. His rise to power and his fall from grace then his rebirth, like the phoenix from in myths and legends rising from his own ashes. However I didnt know much about the subject. So I decided on the subject of Apple computers. Then the more I researched I found a more interesting subject. In the next few pages I am going to attempt to do justice of the accomplishments of Steve Wozniak. No not the other Steve, I found Steve Wozniak a more interesting person simply because I had never heard of the man. I never new he existed. Being of lesser knowledge than most on the subject of computers I found it fascinating. The way Steve Wozniak did things. Steve Wozniak was born in 1950. A baby boomer he grew up in suburban Santa Clara Valley, California with his parents and siblings. His father was an engineer for Lockheed and his mother was the president of a Republican Womens Club. He was into electronics heavily even as a child and young teenager. While looking at a magazine article he spotted a diagram for a simple calculator called the One-Bit-Adder-Subtractor. Woz, as his friends called him, dissected the plans and made improvements. In Cupertino Science Fair he took home first prize with the Ten Bit Parallel Adder Subtractor. It was his first attempt at building a computer. This would be the beginning of a great learning era it would seem. In junior high he had already taught himself how to design programs in computer languages. At homestead high school he absorbed everything he could about electronics and physics. He fare outreached his counter parts in class. After he graduated he went on to the University of Colorado but flunked out. You see he was bored with school because he was so intelligent. At least that is what he tells everyone. Returning to Ca...

Why I Want To Become a Nurse Essay Example | Topics and Well Written Essays - 500 words

Why I Want To Become a Nurse - Essay Example Hence, I believe that adopting nursing as a profession will not only provide me with my dream job, but would also enable me to polish myself as a human being. I chose to apply in the FHCHS Nursing Program for several reasons. Firstly, FHCHS is located at a distance of hardly ten minutes from my home as I live in Orlando. Secondly, FHCHS is one of very few medical centers that can provide their students with sound clinical experience because of its intrinsic association with the Florida Hospital. There may be other nursing schools with links with hospitals but I chose to apply in FHCHS in particular because of the global fame and recognition of the Florida Hospital and this Hospital being the biggest of above 350 facilities of healthcare all over the world that the Seventh-day Adventist Church has to operate. The mere idea of gaining practical experience of learning and working in the Florida Hospital fascinates me. Last but not the least, teachings and ways of this faith-based institution are consistent with my religious beliefs. I would not think of other institutions when I have got world-class education and experience at few paces from my home! I am very good at socializing with people. I am an extrovert. These qualities make me a very good nurse. I have always wanted to have a large social circle and a big network of friends. The level of association and the kind of rapport a nurse enjoys with his/her patients is conducive for long-term association between the two. Nurses can find best friends in their patients because they get an opportunity to attach to them on an emotional level. Thus, I would be making lots of friends as I work more. I want to do a lot of social work in my life. If I can bring a smile on a face with my sweet words and care, that makes my day! Nursing is one profession that would allow me to achieve that because I would be able to work for humanity. I believe that having an

Its long distance away from Sun and the estimated 560 year orbiting time, also demarcates it from the eight well-established planets. Fascinated I was with Dr. Brown’s free-flowing narrative of the events in the lead-up to the eventual discovery, I was also impressed by his mastery of scientific technique and methodology. The way he explained how digital cameras and high-power telescope were used for the project was quite lucid. Toward the end of the lecture, Dr. Brown expressed his displeasure about the tendency among the community of astronomers to give importance to precise definitions of what a planet is. As per the newly coined definition of a planet, both Eris and Pluto do not qualify, thereby leaving the number of recognized solar planets to be eight (stopping with Neptune). Upon hearing this decision to drop Pluto and Eris from the class of planets, I was a tad disappointed. But as Dr. Brown explains at length, such rigid formalizations go against the spirit of astronomy and cosmology. I agree with his view that it is the concept and description which matters, not narrow definitions. Lecture Notes: Lecture organized by Astronomical society - Dr.

PHYSICS (SOLUTIONS) - Essay Example 100Pa). Here, it is essential that the pressure decreases exponentially, i.e. without local minimums and maximums (with the exception of atmospheric fluctuations); so, our criterion mb is valid. Roughly, from the graph attached we can localize km, say, km. e) Let us analyze the pressure curve . It is necessary to note that values of altitude are in log-scale. Nevertheless, even in linear scale dependence is non linear; see ('Atmospheric pressure' 2008) and (Ahren 2000). This can be explained by 'exponential atmosphere' model. This is very rough model for a column of gas extending to a great height; see details in (Feynman et al 1964). Such gas column is supposed to be at thermal equilibrium without any disturbances, so in the model. Model gives an obvious relationship where is the mass of the gas molecule (supposed to be constant in the model), is the acceleration due to gravity, and is the total number of the gas molecules in the unit section of a gas column. Solution of this relationship is ; here . So, the pressure exponentially decreases with increasing of altitude. Such decreasing depends upon the mass of gas molecule: the pressure of lightweight gases (e.g. hydrogen) decreases more slowly with altitude then the pressure of heavy -weight gases (e.g. oxygen). Here, and are weights of a ball... oxygen). Task 2 This task can be solved using Archimedes' principle. Let us make schematic illustration for a helium balloon and all the forces applied to it: Here, and are weights of a balloon and helium inside it, is the net force of buoyancy (for both balloon and helium inside). In accordance with Archimedes' principle, or the law of upthrust, a balloon is buoyed up by a force equal to the weight of the displaced air. A balloon is in state of rest when resulting force equals to zero, i.e. when . a) A balloon is assumed to be a sphere with a diameter of 20cm, so m. Hence, its volume is , or m3, or roughly litres (because 1 litre equals to m3). b) Let us estimate the mass of helium in the balloon. Let us suppose that helium is an ideal gas at and atmosphere. The ideal gas law gives volume occupied by a mole of an ideal gas: litres; here is universal gas constant (Feynman et al 1964). Therefore, the balloon contains moles of helium. The relative atomic mass of helium is 4, so a mole of helium weights 4 grams. Hence, helium in the balloon weights approx. grams. c) Using the graph attached for the task 1, namely dependence , let us define where km. Roughly, mb, say, mb or atmosphere. Let us estimate density of the air at the altitude km. For exponential model of atmosphere we have ; see (Feynman et al 1964). The ideal gas law or allows us to make estimations in terms of air density ; here grams per mole is the mean molar mass of air. For isothermal atmosphere () , so . Then, , so . Let us compute , the density of air at sea level: grams per litre. Let us estimate , the density of the air at the altitude km: or grams per litre. d) It is necessary to note that almost all numeric

Magnetic Resonance Imaging Study of Cerebrospinal Fluid

Magnetic Resonance Imaging Study of Cerebrospinal Fluid Magnetic Resonance Imaging Study of Cerebrospinal Fluid Dynamics in Congenital Brain Anomalies Protocol of Thesis for Partial Fulfillment of Master Degree in Radiodiagnosis By Eman Mahmoud Elsayed Sobh M.B.B.Ch Radiodiagnosis Resident Ministry of Health Supervisors Prof. Dr. Amany Ezzat Mohammed Mousa Professor of Radiodiagnosis Faculty of Medicine Mansoura University Dr. Mahmoud Abd Ellatif Mohammed Assistant Professor of Radiodiagnosis Faculty of Medicine Mansoura University 2017 Introduction Congenital brain anomalies are abnormal developments of the brain that happen during intrauterine life and they are rare among the congenital anomalies of various organ systems. These anomalies of the central nervous system cause approximately 25% of perinatal deaths and account for about 33% of all major anomalies diagnosed at or after birth. The etiology of congenital brain anomalies is poorly understood, albeit some clinical and experimental evidence indicates that a variety of factors, including genetic (chromosome abnormality), environmental (ionizing radiation, toxic agents), infection (rubella and cytomegalovirus), and nutrition (hypervitaminosis A) might play some roles(Chen Zimmerman, 2000). It is important to diagnose these conditions as early as possible due to its far reaching neurological deficit and detrimental outcome. Most of the congenital brain anomalies can be reliably diagnosed by neuroimaging (computed tomography or magnetic resonance imaging) of the brain. Radiologist and treating physician should be aware of various specific imaging appearances and unique signs of these anomalies to avoid delay in diagnosis and thereby further treatment (Singh, Srivastav, Singhania, Devi, 2014). Imaging techniques may be underutilized when clinicians are unaware of the technique or dont recognize its potential. During the last three decades, flow-sensitive magnetic resonance imaging (MRI) techniques have been increasingly applied to quantitatively and qualitatively assess cerebrospinal fluid (CSF) flow dynamics in congenital brain disorders. CSF flowmetry is an extremely valuable tool because it is rapid, sensitive, non-invasive, easily performed and provides critical information in preoperative assessment as well as post-operative follow up of these patients. It is also effective in treatment planning (Yildiz, Yazici, Hakyemez, Erdogan, Parlak, 2006; Zhang Li, 2012). Phase contrast MRI is one the magnetic resonance angiography techniques that have been modified to study the CSF hydrodynamics. The normal and abnormal CSF hydrodynamics can be assessed quantitatively by measuring the peak velocity of CSF in the aqueduct using two-dimensional phase-contrast MRI which demonstrates mechanical coupling between cerebral blood and CSF flow during the cardiac cycle. The normal physiologic motion of CSF is pulsatile which synchronizes with the cardiac cycle. Quantitative analysis of CSF flow in pathways such as aqueduct that is tubular and relatively regular in diameter is desirable because the resulting laminar flow can be measured accurately by phase-contrast MRI. Qualitative assessment provides visual appreciation of the CSF flow through the aqueduct and basal cisterns. (Giiang, Chen, Chen, Huang, Chung, 2000). Aim of Work The aim of this work is to assess the CSF flow dynamics in different congenital brain anomalies using phase-contrast magnetic resonance imaging (PC MRI). Patients Site of the study: Mansoura University Hospital, Radiodiagnosis Department, MRI unit Sample size: 30 patients Duration: within 1 year Inclusion Criteria Patients with congenital brain anomalies diagnosed clinically or radiologically Exclusion criteria Patients / Guardians refusing the procedure Patients have contraindications to MRI studies Patients with associated known arrhythmias Methodology All patients will be subjected to: Full clinical examination Radiological investigations (MRI including phase contrast study of CSF flow dynamics) Electrocardiograph (ECG) Informed consent will be obtained from all patients after full explanation of the benefits and risks of the procedure. Any unexpected risks appear during the course of the research will be cleared to the participants and the ethical committee on time Any patients will be treated in the hospital if any complications occur to them related to the technique Privacy and confidentiality will be maintained to all patients.

Essay --

Should Marijuana be legalized ? In all honesty, should it be? Ask yourself again. How is alcohol legal. Marijuana is much safer and has medicinal use capability . According to Cbsnews.com, in a recent poll in the New England Journal of Medicine, 76% of doctors approve Marijuana for medical use. 1446 doctors asked in 72 total countries. Why is marijuana so widely supported? Because it’s medical capabilities are legit. (I’ll address medical capabilities below) Alcohol totally impairs you and and causes your frontal lobes to malfunction. Its stupid, alcohol, which is actually dangerous is legal and people are still killing themselves under the influence, but Marijuana is good for you yet illegal? It seems as if the government is trying to kill us with such a thing being legal (I don’t drink or smoke so this isn’t biased) . Besides, who really cares? --> If â€Å"potheads† want to smoke, why not just let them smoke? Prisons are for criminals and not for people who smoke a plant that makes them happy. A significant aspect of this controversy is that freedom is being seized. In 2007, arrests for Marijuana alone totalled up to 775,138, dramatically surpassing arrests for all violent crime combined. That’s just ridiculous. People should not be getting incarcerated for smoking a plant that is beneficial to health. Most people just smoke it to reduce stress. Weed smokers are not criminals; rapists, killers, and thieves are criminals. Seriously people, prisons are being flooded. Sticking someone in prison isn’t something that’s cheap. According to Ministry of Justice, the cost of keeping someone in prison is roughly $25,000 a year. These people can’t get jobs, in many states, possession of Marijuana can be ruled a misdemeanor or a felony. A ... ...mount of our population suffers from at least one of these conditions. Moreover, non-cannabis supporters’ strongest argument is the abuse of the plant. The opposition’s argument states that Marijuana is addictive, but recent studies by a professor at the University of Cambridge in England named Leslie L. Iverson, who also wrote a book called â€Å"The Science Of Marijuana†, show that only 9% of Marijuana users develop serious dependency of the plant. Those are overwhelming statistics for anyone trying to keep the plant illegal. In conclusion, Marijuana should definitely be decriminalized. It benefits human health, it will boost the economy if taxed, it will massively reduce the profit of international crime gangs, it will bring down the ever so high crime rate, and will result in prisons not being packed with people who don’t belong there. Support Marijuana legalization!

Ct- 183 †Principles of Providing Administrative Services

CT- 183 – Principles of Providing Administrative Services Understand how to make receive telephone calls 1. 1 Describe the different features of telephone systems and how to use them To using telephone is more easily to pass message to others when you need to, without going to their house or workplace. It is very good to be use in a business employment. For example: if you working in a Reception, then you will always need to pass message around to others staff.You cannot be available go around the building to tell them, because you will always need to be in the reception. Telephone would be the most easily way for you to pass the messages to them, or you can also use e-mail, if they not available to answer the telephone. You need to make sure you deliver the message as soon as possible to others, because it would be some important information or messages they has been waiting for all day.You will always need to make sure you take the correct messages, listen carefully when you on the phone to customers, or anyone that needs you to pass any messages. You need to make sure that the messages you pass to others are up to date, basically is when you taking message thought the telephone, make sure you put the time and all the details you need to know down. If these if privacy message, make sure there’s no one next to you when you on the phone.Telephone is a point to point communication system whose most basic function is to allow two people talking to each other whenever they are. It would be in a different city or country. There is the hold button; you can press it to put someone on hold. Then there is call waiting, caller id, call forwarding, speed dial, group connections. The group connections are mostly for businesses. You can leave voice message to other people. 1. Describe how to follow organisational procedures when making and receiving telephone calls To follow organisational procedures when making and receiving telephone calls is very important , make sure you got the correct numbers when making a call, otherwise it can’t not connect to the person you wanted to call, it will also cost you fees for the call you made. If you working in a Reception it is very important for you to follow organisational procedures, when use transfer, make sure you connect to the right person that caller wants, because it would be a very important call. . 3 Explain the purpose of giving a positive image of self and own organisation The purpose of giving a positive image of self and own organisation is to give you a polite efficient and professional image meaning opening and closing the calls properly, having a pleasant but business-like manner and using appropriate words and phrases in this way everyone will see my organisation in a positive way.
