10 treening müüti

Kõikides valdkondades leiab mingisuguseid tõe pähe võetavaid müüte ning treening ei ole ses suhtes mingisugune erand. Järgnevalt tutvume kümne tavalisima treeningmüüdiga, millest teadlik olles õnnestuks ehk kasvatada rohkem lihaseid. 1. Naised peaksid treenima teistmoodi kui mehed Tahaksin meelsasti kohata seda inimest, kes on veennud paljusi...

Kvalitatiivne uurimustöö Emotsioonide regulatsioon ja stress

Emotion regulation in relation.. 1 Figure 3. The Hypothalamic-Pituitary-Adrenocortical Axis (HPA) Cortisol has been widely used in psychology to measure stress. Cortisol has metabolic effects on liver glucose sythnesis, breakdown of skeletal muscle protein to amino acids and in adipose tissue mobilizes fat. It can also have anti-inflammatory and immunosuppressive actions depending on concentration (Rhoades & Pflanzer, 1989). Most of these physiological effects prepare the body for hostile conditions. Cells of the immune system respond to stress or injury in many of ways (Benoy & Heels, 1998; Mayer & Watkins, 1998; Brines et al, 1996). They secrete a number of cytokines (signalling protein) such as interleu...

Sunflower

9 million metric tons in 1985-86) and about 7% of the oilcake and meal produced from oilseeds. Europe and the USSR produce over 60% of the world's sunflowers. The oil accounts for 80% of the value of the sunflower crop, as contrasted with soybean which derives most of its value from the meal. Sunflower oil is generally considered a premium oil because of its light color, high level of unsaturated fatty acids and lack of linolenic acid, bland flavor and high smoke points. The primary fatty acids in the oil are oleic and linoleic (typically 90% unsaturated fatty acids), with the remainder consisting of palmitic and stearic saturated fatty acids. The primary use is as a salad and cooking oil or in margarine. In the USA, sunflower oils account for 8% or less of these markets, but in many sunflower-producing countries, sunflower is the preferred and the most com...

Acid rains

Acid rains Stefani Nimtsuk What is acid rain? Rain or any other form of precipitation that is unusually acidic It can have harmful effects on plants, aquatic animals, and infrastructure through the process of wet deposition Acid rain is caused by emissions of compounds of ammonium, carbon, nitrogen, and sulfur which react with the water molecules in the atmosphere to produce acids History Since the Industrial Revolution, emissions of sulfur dioxide and nitrogen oxides to the atmosphere have increased In 1852, Robert Angus Smith was the first to show the relationship between acid rain and atmospheric pollution in Manchester, England Though acidic rain was discovered in 1852, it was not until the late 1960s that scientists began widely observing and studying the phenomenon The term "acid rain" was generated in 1972 Can...

Acid rains üldine kokkuvõte

It can have harmful effects on plants, aquatic animals, and infrastructure through the process of wet deposition. Acid rain is caused by emissions of compounds of ammonium, carbon, nitrogen, and sulfur which react with the water molecules in the atmosphere to produce acids . Governments have made efforts since the 1970s to reduce the production of sulfuric oxides into the Earth's atmosphere with positive results Since the Industrial Revolution, emissions of sulfur dioxide and nitrogen oxides to the atmosphere have increased.[2][3] In 1852, Robert Angus Smith was the first to show the relationship between acid rain and atmospheric pollution in Manchester, England.[4] Though acidic rain was discovered in 1852, i...

Betoon

(slide) Moving on, the durability of concrete can be defined as the ability to remain serviceable for at least the required lifetime of the structure of which it forms apart. However there are many factors which shorten the lifetime of concrete (slide) such as: physical attacks, including frost damage, fire, wind and water waves and chemical attacks including sulfates, sea water, acids , alkali-silica reactions and of course corrosion of embedded steel. That's why the durability of concrete needs to be tested. (slide) Firstly, the concrete contains pores and capillaries which fulfill with water. In laboratories several test have been worked out to measure the permeability but in real life we have a similar situations in marine areas. Next, there are three major types of flow constants for concrete. (slide) Firstly there is permeab...

Molekulaardiagnostika kordamisküsimused

Biochemical tests Biochemical tests used in the identification of infectious agents include the detection of metabolic or enzymatic products characteristic of a particular infectious agent. Since bacteria ferment carbohydrates in patterns characteristic of their genus and species, the 2 detection of fermentation products is commonly used in bacterial identification. Acids , alcohols and gases are usually detected in these tests when bacteria are grown in selective liquid or solid media. The isolation of enzymes from infected tissue can also provide the basis of a biochemical diagnosis of an infectious disease. Serological methods are highly sensitive, specific and often extremely rapid tests used to identify microorganisms. These tests are based upon the ability of an antibody to bind specifically to an antigen...

Acid rain

Acid rain is also called acid deposition because this term includes other forms of acidic precipitation such as snow. Acidic deposition occurs in two ways: wet and dry. Wet deposition is any form of precipitation that removes acids from the atmosphere and deposits them on the Earth's surface. Dry deposition polluting particles and gases stick to the ground via dust and smoke in the absence of precipitation. This form of deposition is dangerous however because precipitation can eventually wash pollutants into streams, lakes, and rivers. Acidity itself is determined based on the pH level of the water droplets. PH is the scale measuring the amount of acid in the water and li...
