Oxygen Systems Knowledge is more important now than ever in using oxygen while flying in General Aviation. New high performance unpressurized aircraft are allowing more pilots to fly in the 10,000-18,000ft altitude range. Most pilots have not received proper training in the physiological effects of flying at those altitudes or the advantages and disadvantages of different oxygen systems available. Recreational pilots are most at risk for having issues using oxygen systems due to the lack of structured
Oxygen saturation is a term referring to the concentration of oxygen in the blood. Hypoxemia describes a lower than normal level of oxygen in the blood. In order to function properly, the body needs to be above a certain level of oxygen circulating in the blood to perfuse the cells and tissues. When the oxygen level falls below this threshold, hypoxemia occurs. This may cause certain signs and symptoms to occur. Having short term low oxygen saturation can cause shortness of breath, which is generally
Population and Global Warming In recent years, people have begun to realize the adverse affects of the technologies we use. The tools that humans use to harness energy change the face of the environment around us. When the industrial revolution began, I am sure that no one thought that the innovation taking place could potentially be the cause of a huge change in our surroundings. People were just doing what they thought was the best course of action at that time: the new utilization of resources
Urban Pollution and Waste Management Urban pollution and waste management is a major problem in both the first and third worlds. The increases of major air pollutants in the atmosphere are causing damage to our waters and land. The increase of garbage and waste in urban areas, such as cities, are beginning to look like huge landfills, acid rain is causing forests and buildings to deteriorate, and finally ozone, which is caused from primarily transportation, is slowly suffocating the populations
The Underwater World "There you are, totally weightless, quietly soaring just above the sea floor with only the smallest amount of physical exertion. Small fish come out of their holes to look at you. How about that? You are the curiosity. You are the thing that does not belong. Perhaps this is why you dive. You are taking part in exploring man's last ecological frontier. The very thought would excite anyone whose blood still flows in his veins. The diver is the observer, he looks at everything
4-Week Training Program I'm 15 yrs old, my height is 6'0", and my weight is 10st 3lbs. I have been asked to design a training program for my PE coursework. I will take into consideration training principles, my current level of fitness etc. I would describe myself as a fairly healthy person, and fairly fit too. I perform considerably well at all sports and my endurance level in particular is of a good standard. I have only one injury problem. This prevents me from using my back muscles
reduced and in turn is oxidised], when hot air is blasted into the furnace it reacts with the coke to form carbon monoxide, this carbon monoxide then goes on to react with the iron oxides which are present in the iron ore to reduce [removal of oxygen from a substance] the oxides to metallic iron. The limestone is simply present to react with the impurities removed from the ore forming calcium silicate. Without the limestone Iron Silicate would form therefore reducing the yield of metallic
Environmental Pollution Our environment is affected by our daily actions. The earth is plagued with land, air and water pollution. Some of the problems we face on earth are: deforestation, nuclear waste, acid rain, global warming, overpopulation and some animals are endangered. Air pollution has many different sources. Power-generated plants, oil refineries, chemical plants, and steel mills contribute to about 140 million tons of pollutants into the air every year. Automobiles account
Better Living Although a home takes many years to begin to resemble a comfortable enviroment that we as humans set up to live within a sheltered structure; there are many problems that might be overt and some that we might not readily notice. In this essay I will examine some of the causes that make homes comfortable and bring us as a species closer to nature as well as the causes that might have a negative impact on our lives. With todays technology there have been advances in the homes that
consist of Hydrogen, Oxygen and Carbon. All alcohols are toxic but the amount that can be tolerated by the human body varies for different alcohols. For example drinking small amounts of Methanol can lead to blindness and even death. Ethanol is the only alcohol that can be drunk safely and is found in all alcoholic drinks. Throughout this investigation I am going to investigate to different factors that affect the breakdown of an alcohol. [IMAGE]e.g. Methane (HCO) + Oxygen (O2) Carbon dioxide
of concentration works best. Respiration is not breathing in and out; it is the breakdown of glucose to make energy using oxygen. Every living cell in every living organism uses respiration to make energy all the time. Plants respire (as well as photosynthesise) to release energy for growth, active uptake, etc…. They can also respire anaerobically (without oxygen) to produce ethanol and carbon dioxide as by-products. This reaction is shown in the equation: Glucose Ethanol + Carbon

diagram above) I will then fill the beaker up with cold tap water till it covers the bottom of the test tube (450ml). This is so that we can easily count the oxygen bubbles as they come off the pond weed. Now that the experiment is ready to start, I will turn on the light for one minute, then after the first minute I will count how many oxygen bubbles come from the pond weed in the second minute. I will repeat this stage again once 10 minutes has passed. The preliminary experiment was done to check
The aim of this investigation is to find out how different types of exercise can affect my heart rate. To measure and record my heart rate, I am going to undergo an experimental test. I am going to do 3 different types of exercise: walking, light jog and lastly hard running. First, I will draw out a table to record my results, and then I will measure my resting heart rate for one minute. To make the experiment as accurate as possible, I will take and record each exercise, including my resting
Planning I am going to investigate respiration in crickets and how temperature varies the rate of respiration. The calculation for aerobic respiration is: [IMAGE]Oxygen + Glucose Carbon dioxide + water + energy [IMAGE]6O2 + C6H12O6 6CO2 +6H2O + (J) I will do the experiment safely by making sure that the water will not be too hot or too cold, this is a safety precaution for me as well as the crickets. As we
containing Hydrogen (2 atoms) and Oxygen (2 atoms). Its chemical formula is H ) . In our body we produce Hydrogen Peroxide. Sometimes people may get small patches of white in the skin and this is a result of over production of H O . Although Hydrogen Peroxide left alone will eventually break down, Catalase will speed this reaction up a lot faster therefore in those circumstances it is inserted into the body. Hydrogen Peroxide broken down will produce Water and Oxygen. In our experiment the independent

Here is the full, balanced chemical equation; [IMAGE]Carbon Dioxide + Water Oxygen + Glucose CHLOROPHYLL Or the chemical equation: [IMAGE]6CO2 + 6H2O 6O2 + C6H12O6 With these equations, we are going to see that at what rates photosynthesis happens in this Elodea. We intend to use bulbs, to
Investigating How the Concentration of Hydrochloric Acid Affects the Speed of the Reaction with Marble Chips Introduction ============ There are many factors that will affect the rate of reaction between hydrochloric acid and calcium carbonate. Some of them are as follows: * Temperature - If the temperature is higher, then the molecules in the solution have more energy, causing them to move around more which would mean they would react faster. * The surface area of the calcium
Aim and Hypothesis The investigation that we have chosen to do is how the effect of temperature affects the rate of reaction of hydrogen peroxide to water and oxygen using the enzyme catalase. I predict that the higher the temperature the faster the rate of reaction will be and the more oxygen there will be given off. I've based this prediction on kinetic theory (every 10 degree rise in temperature the rate of reaction doubles.) This is because the substrate will lock
