Maintaining The Vacuum Inside The Tube

Wednesday, January 20th, 2016

During the manufacture of the tube, the air between the two tubes is extracted or removed from the space between tubes to form a vacuum, which eliminates heat loss by conduction and convection. To maintain the vacuum inside the tube, a barium element is exposed to high temperature, which causes the bottom of the tube is covered with a layer of pure barium (silver). This layer of pure barium, is a visual indicator of the internal vacuum tube. If the color turns white silver the vacuum is lost and the tube has to be replaced. Evacuated tube components: 1. Outer tube 2. Inner tube 3.

Empty 4. Selective surface (aluminum nitrate) 5. Gletter barium (element maintains the vacuum absorption) 6. Another layer of pure barium kind of pipe is known as “heat-pipe working fluid in this type of tube is a low-glycol specific heat, which is contained in a copper capillary tube inside the vacuum tube plate absorption tube “heat pipe” is inside a glass tube which has evacuated the air to eliminate heat loss by conduction and convection. The absorber plate is made from a semiconductor coating, this special coating suitable screening to operate in high vacuum ensures high energy absorption and low loss by radiation, the result is a high utilization of available energy What are the benefits of a solar heater? Solar water heaters provide more benefits than a conventional furnace or boiler. The main tangible benefit is the savings that this equipment to stop buying gas. Another equally important benefit is the contribution that a solar heater is on reducing greenhouse gas emissions to the atmosphere (carbon dioxide, CO2), creating a healthier environment. With a solar water heater will prevent the emission into the atmosphere over 3 tons of CO2. How I can save with a solar heater? The savings you can expect from a solar water heater depends on several factors, such as team size, the amount available in your area, and very importantly, the amount of hot water they occupy and how the squatters. The minimum savings in residential equipment is 80% in the current gas consumption for heating water holding. The system pays for itself on average in one year and eight months.

200 years ago in Europe have described isolated cases of "hay fever". And today, allergy affects up to 40% of the population of the globe, and every ten years this figure doubled. Doctors predict that by 2010 the disease will suffer every second inhabitant of the planet! But, despite such a scenario, to fight allergies is possible and necessary. Especially because the latest scientific advances have given doctors and, hence, and we with you, a lot of opportunities to successfully deal with this disease. There is probably no more volatile of the disease than an allergy. One person in the bloom of certain plants will not part with a handkerchief, constantly wiping his watery eyes (allergic rhinitis, conjunctivitis) and sneezing, have another when in contact with the allergen on the skin appear red spots (hives) and there is intense itching, and even more severe manifestation? disordered breathing (angioedema) or even an attack of bronchial asthma.

Somebody's up to a certain Time may not know that he has the disease when he suddenly develops the most serious manifestation of allergy – anaphylactic shock, which may even lead to death. And what usually comes our the average person at the onset of the symptoms of allergies? Suprastin drinks and tries to forget about the fact that he has a disorder, instead of having to go to a doctor and begin treatment. Of course, it is nice feel healthy, but if you do not take care of this ailment in time, the disease will progress, and thus – to take on a more aggressive form.

Moderate Consumption

Today, once again spread belief that alcoholic beverages may be helpful. Maybe so, but only provided moderate their consumption. Excessive alcohol consumption and alcohol remain the most important causes of illness and death. Ethyl alcohol (ethanol) – the main ingredient of alcoholic beverages – is produced by yeast fermentation of starch or sugar. Other substances produced in the process, gives the drink specific taste and aroma. They cause many symptoms of a hangover syndrome.

For example, no alcohol, and contained in red wine polyphenols – the cause of headache. Nevertheless, the main threat to human health when consumed alcohol is just alcohol. The widespread notion that red wine reduces cholesterol in the blood, not scientifically confirmed. At the same time, red wine, increases the blood levels antioxidants that may help prevent aterockleroza, and also reduces blood clotting that is preventing thrombosis. Although alcohol is rich in calories are absorbed almost immediately, there is no the most important nutrients and vitamins. So people get used to drink a lot and little, there is a risk to suffer from nutritional deficiencies such as thiamine, vitamin B, riboflavin, niacin, calcium, magnesium and zinc habit of drinking large quantities harmful to the liver, impairing the ability to metabolize protein and accumulate the vitamin that helps dissolve fat. Consumption of all types of alcohol leads to obesity, but most strongly Obesity develops from the beer and spirits: No wonder the beer lovers there is a characteristic abdomen and increases in the size of the heart.

What Is Bulimia And Anorexia? Part I

Tuesday, January 5th, 2016

Hard to believe that a young man in a bath enclosure to vomit minutes before the pizza hungrily swallowed.

The figures are from the Red interhospital of Eating Disorders in the City of Buenos Aires (Rihter): a network of twelve public hospitals where he is currently serving 400 patients and their families.

"The incidence is increasing year after year and has spread increasingly among men," they say on the Web The Association of Anti-Bulimia and Anorexia (Aluba) exists since 1985 and already treated more than 20,000 cases. Their statistics show that the Now serving 2,000 patients in the headquarters of the country, 10% are men. And the trend is growing: "From 2002 to 2003 saw an increase of 13.8% in male consultations," they say in the institution. And give more details: the average age dropped queries boys.
