Chinese and Western Landscape painting - Essay Example The painting offers a unique feature that makes it one of the greatest surviving masterpieces not just in China but throughout the artistic world. The significance of this painting is reflected in the time taken to finish it. The landscape painting had emerged into an autonomous genre that clearly embodied the nature longing of cultivated persons to escape quotidian world to commune with the universe. The Lackawanna Valley is in the collection of the National Gallery of Art in Washington, D.C. the artist inclusion of various tree stumps in the in his work foreground makes the piece of work unique, The painting exemplifies a significant philosophical dilemma that many Americans were tackling in the 1850s; Growth inevitably demanded the widespread destruction of nature which was not spoiled. My final comment to this piece of art is the effective use of muted colors experience also known as (Tonalism). This makes the paint a unique master piece and a reflective of the era that is such i mportant in the history of American civilization. From these and other observations, I came to a conclusion this work would be associated to the theme of westward expansion and its effects. Both landscape painters from the West and China have embedded their emotion and personal feelings towards the image as opposed to shallow depiction or appearance of the object. Nonetheless, most of the landscape painting from the west like this one in particular is largely affected by faith of Christian religion.

Chinese art - From the Foundation-fount of Painting Essay

Chinese art - From the Foundation-fount of Painting - Essay Example The essay "Chinese art - From the Foundation-fount of Painting" discovers Chinese philosophy of art from the foundation fount of painting. Chinese painters were a conservative bunch. They did not see the relevance of exploring other themes aside from their culture until the Europeans came to their land. However, this does not mean that the Chinese art of painting did not evolve at all. Initially, the painters were tied to making frescoes on temple and palace walls. The frescoes’ themes were mostly religious in temples while in palaces, the paintings were meant to celebrate the ruling family at that time. From frescoes, painting shifted to silk surfaces and paper. Artists relied on their own inspiration and pleasures to come up with the paintings. Painters concentrated on the beauty of landscapes and also strived to keep the memory of prominent leaders and individuals from disappearing once their eras came to a close. From literati paintings that concentrated on landscapes, hum ans and physical things, the craft shifted to formless beings and creatures. The painters became conscious of the spiritual world and they tried to enjoin the visible and invisible world through their paintings. At this point, art was acknowledged as a power to explore both the physical and spiritual world. They believed that physical creatures depended on these formless creatures for survival. Quoting from the text: what has form must rest on the without form. This means that physical life is a continuation.

Coursework Biology Essay Biology coursework: Substrate specificity in yeast AIM: To find out which substrate (glucose, starch, maltose, sucrose or lactose), does yeast, the organism containing the enzyme, breaks down the quickest. Introduction: Usually, every enzyme has a specific substrate that is what we call the â€Å"lock and key† theory. We can try the reaction of an enzyme with different substrates and this enzyme will just work well with one of those substrates. One type of reaction catalyzed by enzymes is anaerobic respiration. (fermentation), made by yeast that uses a sugar as a substrate. This reaction will produce CO2 and energy. Measuring how much CO2 the reaction produces we could know how well the enzyme is working with a substrate, checking thus its specificity. Materials: 5 Ignition tubes Pipette Glucose Maltose Sucrose Lactose Yeast Cotton wool Test tubes Stop watch Ruler Variables: Independent variable: substrate (glucose, starch, maltose, lactose, sucrose), enzyme (yeast), volume of substrate, volume of enzyme. Dependent: volume of CO2 released (measured in mm) Controlled variables: Temperature, pressure, time. Method: 1- Fill 5 ignition tubes, half with yeast (2.0 ml) and half with each corresponding substrate (2.0 ml), using a pipette. 2- Quickly after the mixture is done, place the ignition tubes upside down in a test tube, helping yourself with a pen. 3- Start the stop watch once the ignition tube is upside down in the test tube, and measure the space left (this will be time 0) 4- Place some cotton wool on the top of each test tube in order to block oxygen, and therefore, for anaerobic respiration to occur. 5- Prepare one mixture with the yeast (enzyme), and with water, to act as a control. Treat the control in the same way you have done it with the samples. 6- As anaerobic respiration occurs, CO2 is released displacing the mixture of yeast and substrate into the test tube. Measure the amount of CO2 released during 20 minutes, taking a reading of the empty space inside the ignition tube every 5 minutes. 7- Repeat the experiment 3 times for statistical purposes.

Modern Technology: Are We Too Dependent? Essay -- Internet Computers E

Modern Technology Are We Too Dependent? Internet and television, the twenty-first century has become consumed by these two relatively new forms of media. Devoting more time to one or both of these two creations than ever before, the American public is rapidly coming in from the outdoors and finding the technological marvels of the twenty-first century. Now more than ever television and internet are a major part of people’s lives. The American Society is straying away from their roots as a nature loving community and becoming a community dependent on technology. If comparing stories told by my father about his childhood to those of mine, just one generation apart, drastic differences would be seen. Stories told by my father were of him and his brothers building forts in the woods, going camping for days with neighborhood friends and playing in the woods all day until my grandmother would call him and his siblings in for dinner. My childhood was quite a bit different. I also grew up spending a great bit of my childhood playing outside with my cousins and friends. Building tree houses, playing in the fall leaves, and all the different games kids play were just a few activities of our childhood days. However unlike my father who said he can remember when the first got a television when he was 6, I grew up with television. So I became curious. I wanted to know if most people my father’s age had the same experiences with televisions. In a survey I conducted to test the two generations. The 40+ age group (parents), and the 15-25 age group (children). The following results were found: In the 40+ age group, as a child: 50% watched an average of 5-6 hours per week 50% watched an average of 7-8 hours per week .. ...our direction† (p. 163). He goes on to say that â€Å"If we’re ever to recapture these fundamental kinds of information, it’s necessary to start by remembering just how divorced from the physical world many of us have become† (p.164). These passages from the essay give the results of survey great support. As time goes on society gets further and further away from their roots. Technology is spreading all across the world. Other countries of the world are devoting just as much time to these new technological marvels as Americans do. It is my belief that before it is all said and done every person in every city across the globe will own a television, and be connected to the internet truly making it a World Wide Web.

How Aerial Travel and Cabin Pressure Adversely Affects the Human Body Essay

The idea of humans traveling to the Moon or other areas out side of the Earth’s orbit is mostly scientific. However, when astronauts remain in space, having to re-balance the body to suit less or no gravity compared to the Earth could bring about many changes to the body. Scientists have found that the time required for recovery depends on the time spent in zero-gravity conditions. The longer one stays off of the Earth’s surface, the more damage can be caused. Strictly speaking, even a trip in an Airplane would require safety precautions to minimize damage to the body of this. For example, cabin pressure increased to maintain balance and prevent feeling different to a lower pressure. This essay will consist of two sections. The first will be of flight effects within the Earth’s hemisphere, and how to perhaps prevent damage to the body. The second, and longer section deals with space travel through Zero-gravity and effects of weightlessness on the body and the cou nter-measures to prevent damage to the body. Section 1, flight effects on the passengers, specifically dealing with cabin pressure: Airplanes fly at the cruising altitude of around 33’000 feet, or approximately 10’000 meters. Because the cruising altitude has a cabin pressure lower than air pressure on ground or even under sea-level, the oxygen availability is less and gases within the body expand. This causes the oxygen saturation level of the blood to reduce, which can lead to mild hypoxia, the reduced supply of oxygen to the tissues around the body. Due to the effects of hypoxia, alcohol consumption would affect the brain much more than it would on Earth. As the aircraft makes its decent back to Earth, air must be allowed to flow into the middle of the ear to equalize pressure differences. Passengers often can feel this change in air pressure. People with ear, nose and sinus infections are usually advised to avoid flying because of these changes in air pressure. Air travel in airplanes has less thank 20% humidity. This causes discomfort to the eyes, mouth and nose but does not risk the passenger’s health. This discomfort can be prevented by drinking liquids (water recommended) before and during the flight, and using skin moisturizers. Also passengers with short-sightedness or long-sightedness are advised to wear eye-glasses rather than contact lenses during flight as the contact lenses may dry out. In order to avoid de-hydration, passengers should drink non- alcoholic beverages. Section 2, how traveling through space affects humans Astronauts often experience â€Å"Zero- Gravity† during their travels through space. This zero gravity or micro gravity can bring about health concern to the body if astronauts remain in space for a long period of time. It would be much healthier for crews to live under artificial gravity. In order to prevent any biological changes in the body when experiencing zero gravity, scientists recommend a force of artificial gravity equal to a third of the Earth’s level of gravity. However, scientists still haven’t research affects of artificial gravity on humans but they know for a fact and there is an imbalance in the body due to the shifts of gravity levels. Artificial gravity prevents physiological changes from occurring. In zero-gravity, the body deteriorates. It takes less muscle to move around, so after a long period of time in space, muscles weaken so the body bends. Because there is no tension in space, muscles relax and after a while they atrophy as a result of disuse and eventually disappear. To prevent the fracture of bones, limbs and muscles, all space shuttles give the opportunity for astronauts to do rigorous exercise everyday to keep the muscles strong. Staying in Zero-gravity for months causes bones to lose mass and get thinner, as they are not carrying any weight. This means astronauts must go through rigorous trainings in the spacecraft everyday in order to keep muscle and bone strength. â€Å"When a great deal of the crew’s precious time in space is spent exercising rather than doing science, money and potential knowledge are being squandered for the sake of health. It is a sacrifice, but a necessary one1† In space, receptors in the inner ear allow humans to sense direction. In space, ear receptors don’t receive the same cues and the mind gets used to ignoring the inner ear’s feelings about balance. Hand-eye coordination, posture and balance are all affected by the disorientation of the mind. When astronauts return to earth, they are often â€Å"overwhelmed by dizziness† and have difficulty in maintaining balance. An example of the mind adapting to the new gravity less surroundings would be with Shannon Lucid, who was on board the Russian space Station MIR for six months. The astronaut said â€Å"You just sort of get used to floating around† but we also know that floating around is not all that astronauts do- they must resist the effects of micro gravity on the body. Also, no gravity means no resistance from growing, so some astronauts return to earth some 6 inches taller than when they left. It is only after a few months that they grow down/ shrink back to normal height. This is because of the unloading of spinal discs- because of lack of gravity, the discs in the spine are not holding up or don anything, so they tend to stretch rather than contract. Traveling through micro gravity causes bodily fluids to shift from the lower body to the cephalic area (head), and so people’s faces tend to swell and become rounder than they are on earth. When the brain senses a higher amount of blood than usual, it interprets the situation that there is now an overall increase in the total volume of fluids in the body. The brain responds by triggering the excretion of fluids, making astronauts prone to dehydration. Also, the fluid redistribution can shrink legs as the bones are weaker. These fluids pass through the kidneys, causing kidney filtration rate to increase, bone loss can cause Kidney stones. Fluids that leave the body include calcium loss and bone demineralization. The loss of blood plasma causes temporary Anemia upon the return to Earth. Some crew members get â€Å"space anemia.† Scientists are concerned about the affects of catching this disease on over all crew performance. Blood volume may decrease by 10 percent. The increase of fluids in the head causes the same feeling as when one has a cold and feels blocked in. in space astronauts begin to lose their sense of taste, causing the craving for strong flavorings in the food such as horseradish, mustard and taco sauce. Fluid loss, lack of exercise and diminished appetite cause weight loss as astronauts tend not to eat as much as they would on earth. Meals and exercise are planned to prevent excessive loss. Zero-gravity affects the cardio-vascular system. On earth we must cope with gravity, which sustains or slows down the blood-flow. In zero gravity, there is no gravity force, causing the heart to slow down due to the decreased demands of blood as it travels more freely. The immune system in the body is also affected by weightlessness. In space, one is exposed to illness as the immune response lowers and numbers of anti-bodies decrease after a long exposure to micro gravity. Approximately half of all astronauts are affected by this unpleasant syndrome which affects nausea, headache, lethargy and sweating (taken from NASA sources). Also, minor effects of weightlessness on the body include puffiness in the face, flatulence, weight loss, nasal congestion and often sleeping disturbances. Upon returning to earth, recovery time depends on the duration of stay in space. Muscles are weak and the body is not used to gravity forces, (causing them to feel dizzy) and so some astronauts are taken back in stretchers. This shows why astronauts need to be â€Å"at the peak of fitness.† If in the near future the human race would build space stations as tourist resorts, some would prefer hotels with zero-gravity and some would want partial gravity, which would bring about competition like hotels on earth, which would drive prices low. As gravity affects all biological, physical and chemical processes on earth, building an International Space Station gives new opportunity to study a world without gravity and its affect on animals and other living organisms. Observing the weightlessness effect on these living organisms could teach scientists about biological processes on earth, such as aging and osteoporosis. In the end, we can see that human travel through space is safer under artificial gravity when compared to astronauts being exposed to weightlessness, micro gravity or zero gravity (all three mean the same). Most of the problems mentioned such as fluid loss and muscle deterioration would not cause problems as long as the crew remained in a weightless environment. Remaining in a zero-gravity environment for over a long period of time could cause problems, however. In 1987, in the later stages of his 326-day mission, Russian Yuri Romanenko was fatigued both physically and mentally due to traveling through space. The majority of his day was spent sleeping regaining strength, in the meantime his bones were deteriorating. Some say if many like Romanenko stayed in space for much longer, he may not have survived re-entry to the Earth. Returning to Earth could cause problems as the body is much weaker due to demineralization and atrophy of the bones and shortage of red blood cells. Oneâ€℠¢s balance must now again be readjusted causing many astronauts to feel dizzy when back to a strong â€Å"g† force gravity on earth. Whether or not the large amount of time and money spent on keeping astronauts fit during space flight is worth the scientific findings is debatable. Physiological effects need to be prevented as much a possible. Again, this is usually prevented by rigorous exercise and micro gravity could still be a danger to the astronaut’s health. Many scientists believe that the benefits of transporting/sending out machines (robots) and humans to space, despite the health issues, are nothing compared to the huge benefit that society will receive. Humans will not be perfectly suited to living in a weightless environment, but that won’t stop Astrobiologists and many other research firms like NASA from exploring space. The many benefits of space exploration such as technological knowledge and inspiration easily outweigh the negative aspects.

I read many researches about the benefits and risks of exercise for kids. There are supporters and opponents with these exercises for kids. As well as, Children and adult have response of training exercises but those responses are different of each other. Kids are not like adult. We cannot utilize the same training techniques as them do. Children have physiological, anatomical, and emotional differ than adult and adolescents. Therefore, we can help them to improve their capacities for their personal health. Some of advantages are that kids being engaged in training activity at an early age is that it elevate their awareness on the benefits of a healthy lifestyle. It also increases their confidence levels especially the ones that are involved in sports, walking and positive nutrition programs. More benefits are that exercising reduces kids risk of getting type 2 diabetes, asthma, obesity, stronger muscles and bones, spinal cord injury, and lower blood pressure. Some of the risk are increase stunts, training in too muggy or hot conditions are big risks, and sport injuries to long bones, lower back and muscle injuries that leads to Osgood schlatters disease are very complex. One of the more observed kids program is Biglachy03 that involves knee lifts, bending knees, walking and stretching of different variations to start the warm up.
