The Effects of Cryotherapy on Recovery Student’s Name Institution The Effects of Cryotherapy on Recovery Introduction It was proved by modern medicine that using of cold provides healing of the human body. Local cryotherapy as cold application has become one of the directions of physiotherapy. Currently, the information concerning cryotherapy is abundantly available. Therefore, the main goal of this work is precise and direct research on the effects of cryotherapy and confirmation of the thesis that cryotherapy has positive effects on recovery. To achieve this goal, the paper has been divided into several sections, where the following features will be studied: theoretical data about cryotherapy, mechanisms of influence of cryotherapy on recovery of human body, the main results of cryotherapeutic procedures, application of cryotherapy in specific areas of medical and preventive medicine and counterindication to its use. Theoretical Data about Cryotherapy Cryotherapy is a process of treatment with cold; physiotherapeutic therapy procedures, the effect of which is based on response of the body to the supercooling of outer (receptor) panniculus of the skin. General and local cryotherapy should be distinguished, since, despite the similarity of physical impact, the methods provide fundamentally different results. General cryotherapy irritates all receptor field of the skin and affects the central nervous system. Local cryotherapy causes local effects. Mechanisms…

Question 1 What happen if a person touch liquid nitrogen avoiding the atomic repulsion? It will produce an explosion or nothing will happen? Question 2 It is possible to create an artificial neutron start with the knowledge that humanity have nowadays atoms? (I do not really sure if this question can be considerate part of the course, but at the same time that I watch the podcast, I start to search about neutrons and I found this video in You Tube about the neutron starts, it is origin and it…

INTRODUCTION Worldwide, air pollution is a growing threat to human health and the natural environment. One of the major effects of air pollution is acid rain and it is caused by sulfur dioxide (SO2) and nitrogen oxides (NOx) gases. The combustion of high sulphur content fossil fuels can release harmful toxic gases into the air and therefore pose serious environmental problems. Coal, oil and natural gas are major energy resources available in environment where as fuel combustion processes and…

Some including; ruining the soil, pollute water, and can cause diseases in humans. Most of these problems are caused because in order to support the billions of people on this planet a lot of food needs to be produced. The amount needed is more than what can be produced naturally so fertilizers are pumped into the soil to produce enough crops. National Geographic says almost half of the nitrogen found in our bodies’ muscle and organ tissue started out in a fertilizer factory. Also that the…

In the Monster Who Fed the World you learn about a German Jew named Fritz Haber. Haber was a genius chemist who learned how to take nitrogen out of the air and turn it into a liquid form to contain to use for fertilizer to help grow food for the overpopulated German nation and later the world. Unfortunately, some things and most things can have good and bad uses. Fritz Haber was born on December 9th, 1868. He was the son of a Jewish merchant in a small town. He had all ways longed for a better…

Nitrogen nutrients are also water-soluble which makes them a limiting factor as it dissolves quickly and therefore is not easily accessible to organisms. According to NewsRx editors,”The North Atlantic Ocean is considered a nitrogen (N) limited system once vernal stabilisation of the water column alleviates light limitation and allows phytoplankton growth to deplete surface nutrients to virtually undetectable levels. Ammonium and other regenerated N forms are then the main surface N source for…

allowing the diver to stay under water longer. Pn2 on the other hand activates the urge to respirate. With increasing depths Pn2 will begin to be absorbed into the blood and tissues keeping in mind that with depth, the chest is being compressed simultaneously. Consequences can be the immediate release of Pn2 and Po2 back into the body causing nitrogen narcosis (Encyclopedia, 2014). 2) Decompression Sickness is when the Nitrogen that was stored in the blood and tissues while descending in the…

Nitrogen (N₂) is a colorless, odorless, largely inert gas with a hexagonal structure that is essential to life on earth. This nonmetal is number seven on the periodic table; in its neutral state, it has seven protons, seven neutrons, seven electrons, and an average atomic mass of 14.0067 amu. The electron configuration of this element in ground state is 2-5. Its discovery, safety, availability, and uses are important in understanding this element and its significance. Nitrogenous compounds…

and the Macromolecules. I’ll start with the Macromolecules. These molecules are the four molecules all living things need to survive. The four molecules are Proteins, DNA, Carbohydrates, and Lipids. Each of these molecules is made of Carbon, Hydrogen, and Oxygen at the very least. Proteins have Nitrogen as an added element, and DNA has Phosphate and Nitrogen. The base structure of each molecule has a carbon skeleton. This means that structures have Carbon as the base, in diagrams the carbon…

with -- elemental hydrogen (H2) and elemental nitrogen (N2). The resulting product in this reaction is the covalent compound, ammonia (NH3). Elemental hydrogen and elemental nitrogen is something one should be familiar. Of course, elemental hydrogen is in the water humans drink everyday. However, hydrogen is quite rare elsewhere on Earth because it is nearly fourteen times lighter than the air in the atmosphere, so it rapidly escapes the Earth 's gravity if unbound. Hydrogen is the most abundant…
