Descriptive Essays - The Good Old Truck :: Descriptive Writing Examples

The Good Old Truck    My dad bought his red Dodge Dakota truck in 1995. When he got the truck it had already hit a deer and two cows. Since he has owned it, its value has gone down considerably, even though he has spent more money fixing it than he paid for it. If it was worth as much money as it has cost to keep it running we could sell it and buy a new car. It is red with a stripe down one side-- yes, only one side, the other side has no stripe, I have no idea why this is. There is also a huge dent above the right hind wheel that occurred when a horse tried to jump in the back of the truck. The new, improved, revamped bumper is bent slightly down from the deer and other things that it has hit.    The back of the truck is mostly full of my dad's horse shoeing stuff. It is in no way neat or in any kind of arrangement. There are always empty horseshoe boxes piled to the brim. Underneath the boxes, balls of twine are entangled in old non-usable horseshoes. If you get inside of the truck, you enter a whole different place than the outside world. Notice that I said if you get in; what I mean by this is you can't get in through the passenger side unless someone opens it from the inside. The driver's side door doesn't open all of the time, and when it does you can't possibly slam it hard enough to get it to shut all of the way. Most of the time the passenger side is overheaped with trash, mostly empty pop bottles and cans. Inside it usually smells like horses. My dad shoes horses for a living, so the smell is on him and then is transferred to the seats and anything else that he touches. Also, he keeps his apron in the cab of the truck and it definitely smells like horses. Once in a while when I get in, I get a sniff of a mixture of vinegar and dust. The smell of vinegar comes from the homemade fly spray that my dad makes, and the smell of dust is from all of the dirt that is that has gathered in the corners on the dash. Once I finally get past the aroma of the truck I proceed to turn the key and hope it will start.

Brain death determination

Brain Death Determination When the brain has a lack of oxygen, even for a few minutes, it could lead to loss of brain functions such as a gradual loss level of consciousness or a complete loss of consciousness causing the person to slip into a coma. In the most profound cases, irreversible brain damage and death occurs. Oxygen deficiency can by caused by many things, such as; a brain injury, fall from height, traffic accidents, heart failure, stroke or some neurological disease. That may cause irreversible loss of the brain cells performance.The medical term for insufficient oxygenation to the brain is referral Anglia. Historically, before recent technology the scientists defined death only when the heartbeat and breathing stopped. Afterward, the idea of brain death was announced in 1959 by French neurologists' Moldable and Gluon. They determined this state as â€Å"beyond coma† (D*mice et al. , 2004). Then after around ten years, within the medical community the development o f many types of equipment became available which aided in increasing the longevity of individuals with serious injuries to the brain.Some examples of these devices are ventilators to maintain respiration and heart monitors. These innovations in medicine made the concept of brain death clearer by closely showing the relationship between the respirations or heartbeat and brain. These innovations in the medical field guided the Harvard Medical School Committee to clarify that idea in 1968 (Sass, 2014). After that, it was medically defined as permanent loss of all brain functions, including cerebrum and brain stem due to total death of brain neurons that is caused by decrease of blood flow and oxygenation into the brain (ibid).This essay will discuss the main brain regions that have immediate cause of brain death and their functions, including the required tests of these regions, both clinical and confirmatory, for instance, the Electroencephalogram. The brain carries two major parts, c erebrum and brain stem. When they have any cause of damaged that might be a final result in brain death. Each one has primary roles in a person's life, because they are responsible for the main operations in human survival, especially the regulation of cardiac and respiratory functions.The cerebrum is the largest part of the brain and divided into two hemispheres (Fall & Bergman, 1998). There are main functions for he brain cerebrum without them no human can live. It is important to be concerned with functional specialization of different regions of the cerebrum to guide the treatment of the physician and assists them in making the right diagnosis. The cerebrum has a large primary sensory area, which is responsible for general sensation, for example, smell, vision, and hearing.The motor area is responsible for controlling the skeletal muscles, and the association area of the cortex has operations similar to the sensory areas but more complicated such as behavior, communication and i ntellect (ibid). Secondly, the brain stem is located in the posterior division of the brain and connected to the spinal cord. Beside that it includes three significant parts; medulla obbligato, pens and mandarin. Each one controls principal performance and it is the pathway of sending and receiving sensory information signals from the body to the brain.It has other important functions that have a major affect on a person such as regulation of the respiratory system, consciousness, alertness and awareness (Kiering & Barr, 2009). In general, both cerebrum and brain stem damage may end a arson's life because they contain all the regulation centers for all of the most critical functions that are needed to sustain life. There are many criteria to diagnose brain death. Each country has their organization, but there are general rules and guidelines in determining brain death for patients worldwide.There are important tools to consider when deciding whether the patient is dead or not, befor e the process of diagnosis of death by the criteria. The first tool is a person who is approaching the protocol of brain death qualified? For example, an ICC physician, an anesthesiologist, an internist, a neurosurgeon or a neuron physician are allowed and qualified to perform the tests because they have studied and trained to diagnose brain death, but a dermatologist or an ophthalmologist they have not done training on that.Although, they need to know the state of the patient and must be in a coma with ventilator support and the cause of their comatose condition must be rolled out, for instance, Head trauma, Cardiovascular hemorrhage, cerebral Anglia or primary brain tumor. Next, the cause of brain damage must be clarified six hours before tarring brain functions evaluation. Finally, the patient should not be hypothermia and body temperature has to be above 34 C or 32 C in some countries protocol and the person should not be under sedatives, muscle relaxant, anticonvulsant†¦ E tc Drugs for at least the previous five days. When these tools completed correctly the physician can start the diagnosis in following exam steps. The first clinical examination is to confirm that the patient is in a coma and to make sure a patient is not having any seizure activity in the brain. Furthermore, the physician needs to test he absence of motor response by painful stimulation for both hands and feet. It is required to do these evaluation exams on the standard method before starting the brain stem reflexes test because each exam depends on the previous one to give correct final result.Once the physician has done from the previous evaluation he will start the brain stem reflexes tests, which called the first clinical examination. These are five different exams and begin with papillary response. The light stimulation to test the pupil response by bright beam of light on both eyes, for example, a pen alights. Also, corneal reflex is involuntary blinking and has to be tested v ia a wisp of cotton wool to touch the cornea. Thirdly, cool-cephalic reflex it does perform by moving the head to a different direction and monitor the retina changes during the head movements.Fourthly, vestibule-ocular reflex this another test to activated eye movements by injecting both ears about 50 ml of ice-cold water or saline for adult, but children, less than 20 ml may be used. After all, upper and lower airways stimulation is produce either gagging or coughing. Furthermore, this exam's purpose or provoke the pharynx and trachea. For instance, using catheter leads down to reach into the pharynx and the trachea (Saudi center of organ transplantation, 2009). Accordingly, all those brain stem tests should result an absent responses to declare brain stem death.After finalization of the first examination, it's recommended to not start the second clinical test before 6 hours from the time of first exam end for an adult and after 12 hours for children (above 1 year),24 hours for in fants (above 60 days-I year) and 48 hours for neonate (7 days-60 days). Therefore to have enough mime to perform the confirmatory tests, such as Electroencephalogram (EGG) which is a machine that has 21 electrodes connected to the skull to cover all the brain regions and measures the electrical activity of the brain (ibid).In fact, the EGG and other confirmatory tests are optional in some countries but it is often helpful for the physician to prove that the brain is permanently damaged by having more than one test that confirms his diagnosis and prognosis. The next clinical exam is apneas; it is done to indicate the failure of involuntary respiration. This exam has a specific rotator to perform it, such as an increase the inspired fraction of oxygen without changing the ventilation rate, disconnect the patient from the ventilator for 10 minutes and supply a continuous flow of humidified air.These procedures are done to detect if there is any attempt for the patient to breathe (ibid) . Another test that is sensitive in analyzing the circulation in the brain is transitional Doppler (ETC) this examination detects the velocity of the blood that's circulating in the blood vessels supplying oxygen-rich blood to the brain. It uses ultrasonic waves that are focused onto a beam that is directed at different depths and angles by an experienced operator. The technologist uses sites on the skull where the bone is relatively thin and relatively close to the major vessels whose blood flow velocities are critical.One major vessel that supplies the brain is the Middle Cerebral Artery (MAC). When the blood flow circulation is compromised to the extent that survivability is not possible the ETC shows reverberating waveforms as the blood ceases to flow in it's normal direction and instead is ineffectually regurgitating back and forth without flow in espouse to the heart contraction. Later there are systolic spikes that indicate some increased pressure in the vessel with heart con traction but without effective flowing of blood through the vessel.The last signal that is compatible with brain death is a loss of signal entirely indicating no activity in the vessel and no recordable blood flow in the critical vessels of the brain. In conclusion, the concept of brain death has developed with period of the medical field improvements. The absence of a rich uninterrupted supply of oxygen is imperative to supply the brain and maintain unconsciousness and provide for the populations of neurons to continue to function properly.Trauma, disorders and diseases which impair circulation in the cerebral cortex and brain stem bring about a cascading assortment of symptoms that if not reversed results in death. The protocols and guidelines for brain death determination have been established for the safety of the patient to distinguish between patients who have suffered a life-threatening insult, but who may recover and those unfortunate individuals in whom there is no hope for recovery.

Analysis of “The Shield of Achilles” Essay

The Shield of Achilles is a poem of nine stanzas where the author W.H.Auden has used an episode from the famous Homeric epic ‘Iliad’, as the name suggests. Achilles as we know was the greatest hero of the Trojan War and his shield as mentioned here has its reference in the book eighteen of the Iliad. There Thetis, the sea goddess and Achilles’ mother requests Hephaestus the divine blacksmith to make a shield for Achilles whose armor has been taken away by the Trojan hero Hector when he killed Patroclus to whom Achilles had lent it. Auden here has narrated the episode of the Iliad where this shield is in the making. Interestingly unlike the epical shield which was decorated by Hephaestus with stars and constellation, two beautiful towns full of people, scene of cultivation, a vineyard laden with grapes, herd of cattle, dancing girls and boys, the shield in question presents a scene of lifelessness, destruction and decadence of a moribund society of people. The poem starts with an unnamed woman and a man whom we later identify as Thetis and Hephaestus. She is looking over his shoulder to watch the shield which is being made there. Contrary to her expectations she finds the shield being decorated with barbed wire enclosures and bored officials, weary sentries, detached and dispassionate men folk, a weed-choked-field and a frustrated young boy who knows nothing about love being always exposed to murder and rape. In the poem whenever Thetis peers over the blacksmith’s shoulder hoping to see some beautiful decoration of natural beauty being embossed on the shield, some morbid spectacle is sure to greet her eyes. Finally when Hephaestus leaves after finishing the shield, Thetis is distraught to find a horrific picture which makes Achilles’ doom all the more evident. The poet has used a method of flashback to emphasize the deplorable condition of the modern human society. Whenever Thetis looks over ‘his shoulder’ Auden gives us a glimpse of the beauty of the past by mentioning what she expects to see and what gruesome sights unfold before her. The poem shows a contrast between the ancient world of real heroes and the modern world of debasement. The poet W. H. Auden thus uses the shield of Achilles as a subject but all the beautiful descriptions of Homer have been replaced to show the poet’s disgust with blankness and  shallowness of the modern society.

Thomas Hobbes essays

Thomas Hobbes essays Thomas Hobbes was born in London in 1588. After his receiving his education at Oxford he traveled to various European countries, learning and studying different forms of government. These studies led him to the question of why people allow themselves to be ruled. He also wondered what type of government would best govern in England. In 1651, Hobbes recorded his theories of philosophy in his most famous work entitled Leviathan. In Thomas Hobbes Leviathan, he states that in a humans state of nature he or she is evil, selfish, and cannot be ruled. There is no right or wrong, nor is there justice or injustice. Its basically every man for himself. The world is basically in chaos when humans are in this state. Each individuals main priority is self-preservation. In order to achieve this Hobbes came up with a right each individual possesses in order to achieve this self-preservation, the right of nature. In order to carry out this right, certain laws of nature were created. These laws are acts or forms of behavior that ensure ones safety and preservation. It is here that humans, according to Hobbes, form a society. In fact, Hobbes believed that the only reason individuals left their state of nature was to protect themselves from their own selfishness. A sole leader must be chosen to carry out certain decisions, as well as to set laws. This is why he entitled his philosophy Leviathan, because the word leviathan means sea monster, or overall ruler. Once the people have agreed to follow this ruler, they then have a moral obligation to carry out the law. Because individuals alone do not agree on anything, and are only interested in their own self-interests, a democracy is impossible to accomplish according to Hobbes. Therefore, a monarchy is the best way to govern a society. However, Hobbes ...

Analysis of Variance (ANOVA) - Definition

Analysis of Variance (ANOVA) - Definition Analysis of Variance, or ANOVA for short, is a statistical test that looks for significant differences between means on a particular measure. For example, say you are interested in studying the education level of athletes in a community, so you survey people on various teams. You start to wonder, however, if the education level is different among the different teams. You could use an ANOVA to determine if the mean education level is different among the softball team versus the rugby team versus the Ultimate Frisbee team. Key Takeaways: Analysis of Variance (ANOVA) Researchers conduct an ANOVA when they are interested in determining whether two groups differ significantly on a particular measure or test.There are four basic types of ANOVA models: one-way between groups, one-way repeated measures, two-way between groups, and two-way repeated measures.Statistical software programs can be used to make conducting an ANOVA easier and more efficient. ANOVA Models There are four types of basic ANOVA models (although it is also possible to conduct more complex ANOVA tests as well). Following are descriptions and examples of each. One-way between groups ANOVA A one-way between groups ANOVA is used when you want to test the difference between two or more groups. The example above, of education level among different sports teams, would be an example of this type of model. It is called a one-way ANOVA because there is only one variable (type of sport played) that is being used to divide participants into different groups. One-way repeated measures ANOVA If you are interested in assessing a single group at more than one time point, you should use a one-way repeated measures ANOVA. For example, if you wanted to test students’ understanding of a subject, you could administer the same test at the beginning of the course, in the middle of the course, and at the end of the course. Conducting a one-way repeated measures ANOVA would allow you to find out whether the students’ test scores changed significantly from the beginning to the end of the course. Two-way between groups ANOVA Imagine now that you have two different ways in which you want to group your participants (or, in statistical terms, you have two different independent variables). For example, imagine you were interested in testing whether test scores differed between student athletes and non-athletes, as well as for freshmen versus seniors. In this case, you would conduct a two-way between groups ANOVA. You would have three effects from this ANOVA- two main effects and an interaction effect. The main effects are the effect of being an athlete and the effect of class year. The interaction effect looks at the impact of both being an athlete and class year. Each of the main effects is a one-way test. The interaction effect is simply asking if the two main effects impact each other: for example, if student athletes scored differently than non-athletes did, but this was only the case when studying freshmen, there would be an interaction between class year and being an athlete. Two-way repeated measures ANOVA If you want to look at how different groups change across time, you can use a two-way repeated measures ANOVA. Imagine you’re interested in looking at how test scores change across time (as in the example above for a one-way repeated measures ANOVA). However, this time you’re also interested in assessing gender as well. For example, do males and females improve their test scores at the same rate, or is there a gender difference? A two-way repeated measures ANOVA can be used to answer these types of questions. Assumptions of ANOVA The following assumptions exist when you perform an analysis of variance: The expected values of the errors are zero.The variances of all errors are equal to each other.The errors are independent from one another.The errors are normally distributed. How an ANOVA is Done The mean is calculated for each of your groups. Using the example of education and sports teams from the introduction in the first paragraph above, the mean education level is calculated for each sports team.The overall mean is then calculated for all of the groups combined.Within each group, the total deviation of each individual’s score from the group mean is calculated. This tells us whether the individuals in the group tend to have similar scores or whether there is a lot of variability between different people in the same group. Statisticians call this within group variation.Next, how much each group mean deviates from the overall mean is calculated. This is called between group variation.Finally, an F statistic is calculated, which is the ratio of between group variation to the within group variation. If there is significantly greater between group variation than within group variation (in other words, when the F statistic is larger), then it is likely that the difference between the groups is statistically significant. Statistical software can be used to calculate the F statistic and determine whether it is significant or not. All types of ANOVA follow the basic principles outlined above. However, as the number of groups and the interaction effects increase, the sources of variation will become more complex. Performing an ANOVA Because conducting an ANOVA by hand is a time-consuming process, most researchers use statistical software programs when they are interested in conducting an ANOVA. SPSS can be used to conduct ANOVAs, as can R, a free software program. In Excel, you can do an ANOVA by using the Data Analysis Add-on. SAS, STATA, Minitab, and other  statistical software programs  that are equipped for handling bigger and more complex data sets can also be used to perform an ANOVA. References Monash University.

What to Do When You Miss Class

What to Do When You Miss Class Regardless of how good a student you are, how detail-oriented, hard working, or diligent, you can be certain that you will miss a class at some point in your academic career. And likely many more than one. There are many reasons for missing classes, ranging from illness, emergencies, and bereavement, to hangovers and a desire to sleep in. Why you missed class matters. If it was for irresponsible reasons, your absence signals that you need to take a closer look at your obligations and priorities. What do you do after missing class? Do you just show up at the next class and start fresh? What about material that youve missed? Do you talk to professors? 7 Things To Do When You Miss Class (Before and After Your Absence) 1 . Understand that some faculty, especially graduate faculty, take offense at absences for any reason. Period. They might be a bit more warm to students who were gravely ill, but dont count on it. And dont take it personally. At the same time, some faculty​ members  dont want a reason for your absence. Try to determine where your prof stands and let that guide your behavior. 2. Be aware of attendance, late work, and make-up policies. This information should be listed in your course syllabus. Some faculty​ members  dont accept late work or offer make-up exams, regardless of the reason. Others offer opportunities to make up for lost work  but have very strict policies about when they will accept make-up work. Read the syllabus to ensure that you dont miss any opportunities. 3. Ideally, email your professor before class. If youre ill or have an emergency, try to send an email to inform the professor that you cannot attend class and, if you wish, provide an excuse. Be professional - offer a concise explanation without going into personal details. Ask whether you may stop by his or her office during office hours to pick up any handouts. If possible, hand in assignments beforehand, by email (and offer to hand in a hard copy when youre back on campus, but an emailed assignment shows that its completed on time). 4. If you cannot email before class, do so afterward. 5. Never ask if you missed anything important. Most faculty  members feel that class time itself is important. This is a surefire way to make a professors eyes roll (maybe inwardly, at least!) 6. Do not ask the professor to go over what you missed. The professor lectured and discussed the material in class and likely will not do it for you now. Instead, demonstrate that you care and are willing to try by reading the course material and handouts, and then ask questions and seek help for the material that you dont understand. This is a more productive use of your (and the professors) time. It also demonstrates initiative. 7. Turn to your classmates for information about what happened in class and ask that they share their notes. Be sure to read more than one students notes because students have different perspectives and might miss some points. Read notes from several students and youre more likely to get a complete picture of what happened in class. Dont let a missed class damage your relationship with your professor or your standing.
