Viruses And Its Effects On Humans - 1404 Words

Though viruses may seem as though it only has the potential to cause harm, recent studies have surfaced to change its bad reputation. Common known viruses such as Ebola, rabies, influenza, HIV and more are known to show harmful reactions to humans, sometimes even possible to cause death. Because of the way they work, viruses such as the human immunodeficiency virus has been looked into in terms of reprogramming, ending in a result that could possibly be an option to treat another catastrophic epidemic of humans, cancer. What are viruses? Viruses are small infectious agents that replicate inside the living cells of other organisms. Viruses particles are one hundred times smaller than a human cell. Viruses are not alive. They cannot grow†¦show more content†¦In the lytic cycle, the virus particle attaches itself to the host cell in a process called absorption. The virus particle then injects either its DNA or RNA into the host cell, in a process for entry. This invading DNA or RNA takes over the cell and recruits the hosts enzymes**.(add citation)** These enzymes now start making new virus particles, in a process called replication. The particles of the virus that were created by the cell could then come together to form new viruses. These now newly formed viruses can then kill the cell so they may break free through lysis and search for a new host cell, in a process called release. The lysogenic cycle is another form of viral reproduction that involves the fusion of the nucleic acid of a bacteriophage with th at of a host. Their viral genome will integrate with host DNA and replicate along with it fairly harmlessly. This virus then remains dormant until the hosts conditions deteriorate, which is when prophages become active. At this point they initiate the reproductive cycle, resulting in lysis of the host cell. As the cycle allows the host cell to continue to survive and reproduce, the virus is reproduced in all of the cell’s offspring (George 1996). How does HIV affect the body? Infection with HIV is particularly troublesome for the immune system because it infects and destroys immune system cells.(Bagby, 2015) Untreated, the disease progresses over a few years to AIDS,

The Hidden Recesses Of The Mind - 1045 Words

He that has eyes to see and ears to hear may convince himself that no mortal can keep a secret. If his lips are silent, he chatters with his fingertips; betrayal oozes out of him at every pore. And thus the task of making conscious the most hidden recesses of the mind is one which it is quite possible to accomplish. - Sigmund Freud, Dora:An Analysis of a Case of Hysteria All human writing contains hidden pieces of the unconscious mind buried within layers of symbols and psychological defenses. When one writes something, all previous experiences, feelings, and thoughts are brought together to form whatever the person wishes to convey. Hidden emotions and feelings that are being suppressed by psychological defences are often expressed unconsciously revealing the speaker s hidden secrets. Logan LeBlanc’s squibs contain multiple different psychological defences, but Intellectualization and escapism appear the most often; they are usually used together in his writing. Almost every time a very personal topic comes up in one of LeBlanc’s logical trains of thought, the conversation suddenly changes to either something that he deems happy or acceptable, or he starts stating facts about one topic or another. One example is when he says â€Å"This would mean that even though most people are strangers, they are still family in a way† after talking about the relationship between family and strangers in squib number one.

Bernoullis Theorem Apparatus free essay sample

The objective of this experiment is to determine the relationship between pressure head, velocity head, and static head and compare it with Bernoulli’s Theorem. The total head of flowing liquid between two points remain s constant provided there is no loss due to friction no gain due to application of outside work between the two points. So basically the apparatus used for this experiment consist of a venture tube with different diameter at certain part, 8 tubes of water manometer, a rotameter, stainless steel tube and a stop watch to record the time of the water flow. The procedures are simple, after connecting the hydraulics bench outlet to the test set, the pump is started. Then adjust the flow rate to 10, 15, 20 L per minute. The flow rate and readings for each manometer should be taken and recorded in the table provided. The total head at any point is indicated on tube no. We will write a custom essay sample on Bernoullis Theorem Apparatus or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page 7. As for the result, we need to obtain the time needed for the flow to fill up 4L. Then we can calculate the flow rate followed by the velocity of the flow at any point. With the velocity of the flow for each point are known, thus we can calculate the velocity head for each point. As for the static head value is taken from the manometer readings. We can observe that even point 1 and point 8 have the same diameter but the flow rate manometer readings might differ a little which is due to the friction loss along the venture tube. There might be some error occur in this experiment as the valve in this apparatus used contain some defect which will affect the result of the experiment. After conducting this experiment, we can conclude on the statement of Bernoulli’s Theorem that relates between velocity head and static pressure head, where the increase of velocity head is compensated by a reduction in the static pressure. Objectives The purpose of this experiment is to investigate the relation of pressure head, velocity head and static head then compare with Bernoulli’s Theorem. Besides, this experiment also aims to determine the total head and the friction loss between two points in the Venturi tube with same cross sections. Theory: Bernoulli’s Theorem States ‘The total head of flowing liquid between two points remains constant provided there is no loss due to friction no gain due to application of outside work between the two points. Total head (HL) of flowing liquid is made up of Elevation Head or Static Head (Hs). Another example of friction loss is as point 1 and point 8 have same diameter, we should expect that the static head are equal. But as shown is the result the values are not the same in fact the value of point 8 are much lower than that of point 1. This has shown the existence of friction loss along the venturi tube. Besides that, error or mistakes committed during the experiment may also affect the end results. There are several errors and mistakes might have occurred during the experiment which affected the result. The errors and ways to avoid these from happening in the future are as follow: I. There might be some air or bubble that entrapped in the venturi tube or the manometer. This will affects the flow of the fluid in the venture tube and also affect the readings of the manometer. To this error from happening, we should allow the fluid to flow until there is no visible bubble before starting the experiment. II. During the experiment, we encounter some problem on the valve of the apparatus. It seems that it could not be tighten. Even after that it was fixed but this might slightly affect the result due to the defect of the valve. Therefore any broken parts of the apparatus should be replaced and maintenance should be done on the equipment to ensure that it is in a good condition. III. Some unnoticed leakage or blockage in the equipment might also affect the result. Maintenance on the equipment should be done regularly to avoid this. IV. Human errors such as parallax error and some delay in pressing the stop watch might also hugely affect the results of the experiment. The only way to avoid this is to repeat the experiment for several times. V. Manometer that fluctuates all the time makes it harder to get the exact values and therefore influence the accuracy and consistency of the data. So we should wait until it steadies at a certain value before taking the reading. Conclusion This experiment has demonstrate the relation of pressure head, velocity head and static head and compare it with the Bernoulli’s theorem which stated that The total head of flowing liquid between two points remains constant provided there is no loss due to friction no gain due to application of outside work between the two points. In conclusion, the total of velocity head and the static head should be equal to the total head which is the manometer value point 7. And the reason that the total is not equal is due to the existence of friction loss along the venturi tube. From this experiment, we can notice that smaller cross sections of Venturi tube will have higher velocities, thus the cross section of the tube is inversely proportional with the velocity. Flow rate will affect the velocity head. References Hydrology and Hydraulic Engineering I Laboratory Lab Manual Appendix

Omelas Moral Dilemma free essay sample

In The Ones Who Walk Away from Omelas Ursula LeGuin is raising the moral dilemma of justice vs. happiness. The happiness of the citizens in Omelas depends on the suffering of a child locked in a closet. She briefly describes the contrast between the child’s situation and the citizens’ position, portraying a moral dilemma, which is when you have to choose to do one of two equally unpleasant things. LeGuin portrays an ideal life â€Å"boats in the harbor sparkled with flags, women carrying their babies and chatting as they walked and streets filled with music and dancing† (1311). The morning air was clear, the peaks wear crowning with snow and the sweetness of air trembled enough to bring joyous of belles through the streets of Omelas† (1311). Summer has begun and they gather together at the Green fields to smell the marvelous smell of cooking. â€Å"The youths and girls line up there horses and begin to start the line of course† (1313). We will write a custom essay sample on Omelas Moral Dilemma or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page A child sits alone playing his wooden flute sending a sweet and magic tune, people pause and listen to the young child but do not speak to him. However, she also portrays the situation as extremely injustice. In a basement under one of the beautiful public buildings of Omelas† (1313) is a child that is sacred and alone. The child is observed, he cries out at night the pain and suffering. He sometimes speaks out â€Å"I will be good,† â€Å"Please let me out† (1314). Very little light sweeps through the cellar the child has no understanding of time. Others content merely know the child is there, it is explained to young children when they are capable of understanding. Young children often clutch for weeks of no real joy. They take their pain and suffering home of the young child locked away in the underground cellar. Some of the people of Omelas understand why the child is there and the others do not. Even when the issue is being explained people still don’t understand they are shocked and sickened. Words are not spoken to the child tears of injustice, compassion, and happiness perhaps is of no knowledge to the child. Yet tears and anger of the acceptances to their helplessness is the existence that they know the child is not free. Men and women walk the streets, and weep at the fact of the child in the cellar. The child in the cellar is the existence of why the Omelas treat their children gentle but yet full of compassion and joyful love for happiness. The tearless rage, treatment, freedom, and acceptance of the Omelas to the child have long ever to be free and fearful. Therefore, happiness seems to be at the expense of justice. â€Å"The folks were not simple folk, though they were happy† (1312). They would not use the word â€Å"cheer† anymore because they weren’t cheerful (1312), but yet all smiles would become archaic (1312). They didn’t have slaves or swords nor did they use their people as barbarians (1312). Yet their society, rules, and laws were especially less complex, but the people of Omelas â€Å"were not less complex than us† (1312). The trouble was encouraged by sophisticates considering happiness rather than being stupid† (1312). Their children were happy, mature and intelligent; perhaps happiness is based on what is neither necessary nor destructive. Omelas strikes some as all smiles and good people. The people of the Omelas have guilt, and the joy they have is built on successful slaughter. What swells the hearts of Omelas is the boundless, generous and magnanimous triumph in souls of all men and against some other enemy. The people of Omelas often stray away from the village and straight over the mountains and through the farmland never to return. The people’s reactions towards the child’s faith, the city development, and survival, make it a real big dilemma. The goodness of the Omelas threw away small improvements for the small chance and happiness of one. Adults and other children view the child locked away in the basement under the beautiful buildings. No matter the disgust, and sorrow they have for the child, wanting to do something for him would have Omelas end in wither and would be destroyed. The people leaving the village realized that justice was more of important moral value, than having one innocent child sacrifices his life for everyone’s happiness. Therefore, I believe â€Å"Ones Who Walk Away from Omelas† is a moral dilemma of justice vs. happiness. The people realize that justice is more of an important moral value than to have one child suffer to have happiness for everyone. To have one sacrifice his life and happiness for other people’s happiness is not right. People experience happiness first before experiencing misery. The acceptance to happiness and existence is in the eye of the holder. The compassion and joyful happiness of one shall not be taken for granted suffering of one gives opinions of freedom, nobility and an understanding of right or wrong to others.
