...Name: Tutor: Course: Date: Rhetorical analysis writing Pleasant point of view Immediately I arrived at the appointment spot I stood gazing at the view she would approach. Everything was live and encouraging including the caressing breeze from the palm trees near the small artificial beach. Behind the narrow tunnel, two pretty twin girls played their trumpets in such lulling rhythms that stole away the boredom of the park. They seemed to draw the attention of the music lovers as they easily shifted from tune to tune. The parrot picked the words and helped to amplify the popular classical compositions that everybody associated with in Indiana. Even the gardener in the flower bed extension realized the vivacity in the park, unlike her early morning hour. The rose, lily, and hibiscus flowers intermarried like formally wed couples that cited the parents for the good parenthood they had attained. She adjusted her helmet and radiantly gazed at the tunnel point a time when an oak tree danced shaking off its bright red, blue and orange canopy of leaves. The leaves fell from above like the rare rain in the semi-desert covering everything that the tree’s shade touched. It sent a spring of motion among the other hidden creatures including the white and black -spotted wild cats who whimpered and rolled over the blanket that had formed in their place. The horse neighed in a rather merry mood as the queue of children anxiously anticipated to take a ride that quantified the time spent...

...iLab week 1 Essay SCI 228 Nutrition, Health, and Wellness iLab Week 1 Essay There are 14 parts of the digestive system. They include the salivary glands, tongue, pharynx, esophagus, stomach, liver, pancreas, gall bladder, small intestine, large intestine, appendix, rectum, and the anus. Food we eat first enters our mouth, which is where you find the tongue. We know it’s in there because it tastes the food we put in our mouth. You will find the salivary glands in 2 spots, under your tongue and behind your tongue. The best way to remember that it’s located there is to known that it releases saliva and there is always saliva on your tongue. Our pharynx is found in the back of the mouth. To remember it is located there I use the first half of the word which sounds like far, and then use that as a saying. The Pharynx is the start of a far travel. This is down the esophagus. The esophagus starts at the back of your mouth and runs down into your stomach. I remember it’s located there because I feel food go down my esophagus when I touch my neck. Our stomach is located underneath our heart. Most people love food. I use that to remember where our food goes after we swallow, under the heart into the stomach. The pancreas is located behind the stomach. It’s located behind the stomach because it needs to use the blood streams coming out of the heart to add enzymes it made. After the stomach, food will go into the small intestine. The best way to remember that the small intestine...

...Uses of Hypnotherapy to treat a medical condition Introduction The purpose of this essay is to describe and explain the uses of hypnotherapy in the treatment of a medical condition. For this essay I have chosen to look at a chronic life limiting illness called Motor Neurone Disease. This is a disease that can affect many different aspects of a person’s life and is very aggressive in its symptoms. I have met quite a few people with this condition whilst working in the Neurophysiology department at the QMC, where all the nerve and muscles studies and EMG’s are performed. It not only changes the person’s life but also the lives of the people around them. I found this research both upsetting and informative. MND is a progressive degenerative disease which sadly has no known cure and sufferers will usually die within 5 years of the onset of the disease, there is no way to tell that you have this disease but there are many warning signs such as difficulty with speech, walking and dropping things due to not being able to grip correctly. MND is an unusual disease that damages nerve cells that the brain would usually use to send messages to the muscles and spinal cord where the upper and lower motor neurones are negatively affected. This then alters the muscle strength and can result in muscle loss. Theses neurons also if not working correctly will affect the messages sent to the brain giving the commands the body needs to enable walking, swallowing and any other muscle use. This...

...In order to fully comprehend classical and operant conditioning , first we need to understand what exactly behaviourism is and what it focuses on. This essay will outline behaviourism and look at the explanations for how we learn, these include classical and operant conditioning. Both learning methods have several practical applications used to treat people, these will also be discussed. Behaviourist’s believe that when you are born your mind is blank and behaviorism focuses on learning based on the concept that all actions are acquired through conditioning processes. John Watson who was considered “the father of behavioursim”, argued that conditioning occurred through interaction with the environment and our responses to the environmental stimuli shape our behaviours. Conditioning can be separated into two types, classical and operant. Classical Conditioning is defined as the conditioning of reflexes so that they occur in response to new situations. It was first discovered by Ivan Pavlov when he was working on dogs, studying their digestive systems. He noted that the dogs produced saliva when a bell(auditory stimulus) and food (unconditioned stimulus) were presented together. Eventually the bell alone(conditioned stimulus) would come to evoke the salivating response(conditioned response) . The link between the saliva and the bell is defined as conditioned stimulus and response because the dogs were conditioned to associate the bell with receiving the food. However if the...

...d. 14/9/2011 Essay 1 Living With Strangers The big city. Just the word gives a wealth of associations: The big city is noise and traffic, a lot of life. The big city is the anonymity in the crowd. The place where everything you do is not noted by others. The big cities came as a result of the increasing urbanization after the industrialization in the 1800s when a lot of people moved from the country to the cities to get a job. But the fact that you are now living with hundred thousands or millions of other people creates many challenges. It can especially be a problem how to deal with all the people who you do not know and who you do not manage to get to know. That is exactly the theme the American writer Siri Hustvedt takes up in her essay Living With Strangers published in The New York Times in 2002. The text is built up in three main sections. In the first part Hustvedt tells her personal story about her moving from the country where everyone knows each other and everyone always greets everyone, and to the big city New York where nobody greets each other and millions of people live side by side. She quickly learns the unwritten rule which says something like, pretend like nothing is happening, “It didn’t take long for me to absorb the unwritten code of survival in this town (…): PRETEND IT ISN’T HAPPENING” (line 17-20). Hustvedt quickly captures the reader’s interest by telling this personal story in the beginning because the reader can identify herself with her and...

...This essay will focus on dehydration, and water in the body how it is function. The reason water essential to health maintenance and what water can do to the body if not enough is obtained. This essay will mention how the body level based on hydration has on alcohol and caffeine. Sodium, potassium, and chloride compare and contrast how these different electrolytes function in the body. I will also explain the steps to take to ensure people not become dehydrated. Dehydration means excessive loss of water resulting in depletion of body fluids (Grosvenor & Smolin (2006). Dehydration is that you lose more fluid than you take in which occurs because there is not enough water and other fluids in the body to function normal. Dehydration can be prevented by drinking about eight- nine glasses of water a day. Water is essential to health maintenance is that over half of your body weight is water. Every cell in our body carries out the presence of the universal solvent. A person sweat during exercise water with waste is flushed out of your body. Water is needed to prevent dehydration this helps to maintain proper metabolism in our body. All the body tissues varying proportions of water is found in 60% of body weight in adults is water, in a child the water percentage is the highest. The functions of water in the body are for digesting food. Water also helps to cushion our joints and prevents shocks in them. A person will know when he or she have enough water when he or she urine will...

...and the city nearly busting at the seams with people. You stand there on the sidewalk filled with awe and taking it all in while your sides are being assaulted by the passers-by and their elbows. Sometimes it seems quite hopeless to make someone notice you and send a smile your way, because while you acknowledge people they don’t acknowledge you. They’ve all grown accustomed to the oblivion that comes with big city life, or rather the feigned state of oblivion. We may all get drawn to it thanks to numerous movies and TV series romanticising it, but in fact adjusting to the big city, where things are getting lively, is somewhat of an acquired taste. This is some of the things that Siri Hustvedt emphasises in the essay “Living With Strangers”. Siri Hustvedt begins her essay with writing about the “culture shock” she is met by when she first moves to New York City. In her hometown in rural Minnesota it was a custom to greet everyone that you walked past even if you didn’t know the person. The most important part of the greeting when passing by someone was to actually speak the word “hi”. “When I moved to New York City in 1978, I quickly discovered what it meant to live among hordes of strangers and how impractical and unsound it would be to greet all of them.” (p. 1, l. 6-8). You will quickly realise that you need to adapt to the new environment and follow the rules that people in the vicinity live by. Another thing that Siri Hustvedt emphasises is a law that she learns is the way...

...Student: Trieste S. Arrington School: Penn Foster Essay: Ways to Get Your Children to Clean Their Room Date: 06/27/2016 The Russian psychologist Ivan Pavlov was interested in the study of gastric function. He examined dogs' saliva when he fed them. While studying the dogs, Pavlov noticed they would salivate before they were fed the food. He then investigated the dogs' behavior and found that the dogs would salivate upon hearing the sound of a bell ringing, and moments later, they were given the food. It was at that time when Pavlov's discovery took place. By taking the unconditioned stimulus, which was an alarm sound, and a neural stimulus, which was something the dogs had been born with, and joining the two stimuli in a close range of one another, we learned that this phenomenon was called classical conditioning. We learned from classical conditioning that humans can learn. Children can learn to clean up their rooms by presenting children with an unconditioned stimulus and by sometimes adding incentives so that the children will associate the incentives with cleaning up their rooms, which would create positive cleaning habits that would last a lifetime. Another way of classical conditioning would be for children to watch their parents clean. Children often imitate what they see, so it would help the child or the children to witness how cleaning should happen by watching how their parents clean their home. Having children learn to clean up after themselves...

...The Veldt Craft Moves Essay Technology is something that people take for granted and it can take over their lives. In “The Veldt” the technology of the new world has taken over the kids lives and their parents lives. The kids have been taken over by the nursery and they have been acting weird and the parents try to fix it. Ray Bradbury focused on multiple craft moves such as descriptive language, foreshadowing, flashbacks, similes, and inner thinking to show what the characters are feeling and to make the reader think. The author uses foreshadowing to help the reader comprehend what will happen later in the story. Foreshadowing is a hint to the reader of what will come later. Sometimes it is used to show something that will be reiterated throughout the story. An example of this in the story is that the character hears a scream that sounds familiar and throughout the story that sounds comes back and they hear it many times. In the text it states, “Did you hear that scream?” This is something that the characters hear all throughout the story and it gives you a hint to what is next. The author uses descriptive language throughout the story to give detail and give the reader a good idea of what the...

...Casey Anthony Case Dixit and Gothwal (2015) define criminal law as a rule that control the social conduct and prohibits the acts that are harmful to the people and as such, threatening the safety and the welfare of societal members. Morse (2015) contends that criminal laws define the punishment levelled on the people who break the prescribed societal conduct while Holland (2015) asserts that criminal laws refer to the state laws, which make certain actions illegal and punishable by fines or imprisonment. Accordingly, the case of Casey Anthony falls under the criminal and as such, the forensic evidence gathered from the trunk of her car makes her criminally reliable, as the said evidence is admissible in the court of law. The forensic experts from the Federal Bureau of Investigation (FBI) examined a band of hair recovered from her vehicle, which exposed evidence of apparent decomposition. Forensic analysis of the recovered band of hair showed consistence with the band of hair of the deceased. The FBI experts who conducted forensic analysis on the band of hair told the court that the sample had many consistencies in relation to the post-mortem banding. Moreover, microscopic hair examination specialist told the jurors that the root portion of the air was dark and, therefore, consistent with the evidence presented by the FBI. The analyzed evidence showed that the hair was evicted forcibly from the deceased. Further, an investigator of the crime scene testified that that there...

...Healthcare workers have a guidelines on how to prevent and control the spread of infection when providing care for all hospitalised individuals in healthcare. Workplaces are obliged under the Occupational health and safety Act (2004) to provide a safe work place by training the staff the infection control procedures, instructing them to use the right equipment or techniques to prevent infections from spreading over. Every health worker plays a big role to minimise the transmission of infection by following the workplace infection control procedures. Standard precaution, additional precaution, sharp safety, exposure policy, staff vaccination, single use policy and waste management policy are a principle that break the chain of infection.

Standard precaution includes good hand hygiene, the use of personal protective equipment(PPE), appropriate handling and disposal of sharps and other contaminate waste, and use of aseptic techniques. Berman et all. (2012) describes that hygiene is widely recognised to be the single most effective activity for minimising the transmission of infections.An inappropriate techniques when washing hands can lead the areas of the hands to still be contaminated by micro-organisms...
