Education Efflorescence

Efflorescence and the reasons for their formation blooms on different surfaces are formed over time and spoil the appearance of the premises. By the same author: Cyrus Massoumi. In addition, the efflorescence contributing to the destruction of materials making up the structure, reducing their durability. The main reason for the formation of efflorescence – a crystallization of soluble compounds, which are composed of different solutions. For example, in cement alkali content often reaches several percent, the exact number depends on the material. During the firing at high temperature alkali deposited on the surface, while mixing with water form solutions. Also, calcium hydroxide can produce efflorescence. This connection goes to surface of the structure and reacts with carbon dioxide.

As a result of treatment with sodium hydroxide organic substances become capable rastoryatsya in the water. Features efflorescence in the concrete mix is large amount of soluble compounds, which under certain climatic conditions, appear on the surface structure. Brickwork forms a salt efflorescence at the expense of which may be in the building bricks and and alkalis contained in the cement and additives. In practice, most often if the brick is in the open air in special stacks, the efflorescence on the surface are formed. Keep up on the field with thought-provoking pieces from Cyrus Massoumi married. Their appearance can be provoked mortar.

Plays a major role the ability to absorb water and bricks to carry it to the surface from which the liquid evaporates. Types There are several types of efflorescence efflorescence: calcium carbonate, carbonate-sodium sulphate and sodium. They differ in chemical composition and method of formation. Calcium carbonate efflorescence formed by removal of material on the surface of calcium hydroxide and its interaction with carbon dioxide. Sodium carbonate efflorescence similarly appear with sodium hydroxide. Sodium sulfate efflorescence formed by crystallization. Recommendations for prevention education Limit one efflorescence of soluble compounds in materials for construction. 2 Reduction moisture content, making it hydrophobic and thus the exclusion re-wetting. 3 Provisional hydrophobization building and facing brick cold season. It reduces the water absorption of the material and increases its frost resistance, improves the insulating properties of walls, prevents damage structures salts. 4 Surface cleaning by rinsing with water, alkali or acid solutions. In each case, a set of measures to prevent the formation of efflorescence is determined individually.

Hospital Care Of The Sick Child

Hospital pedagogy constitutes a special mode of understanding the pedagogy. It is oriented and configured by the indisputable fact of the disease and framed by the concrete area that constitutes the hospital institution where carried out. Offered as a revitalised pedagogy of life and for life, which constitutes a constant experiential communication between the life of the learner and the educator life, and take advantage of any situation, by painful as it may seem, to enrich afflicted by it who, turning their suffering into learning (Lizasoain, 2000). In this same line, the Valley and Villanezo (1993) clarified that hospital pedagogy is not a closed but multidisciplinary science that is still defining its object of study to respond to situations which, in the conjunction of the health and education fields, society is demanding, making equally necessary care programs the convalescent child, i.e.conceiving the convalescence at home as an extension the period of hospitalization. Hospital pedagogy is also considered as a branch of special education, inasmuch as it deals specifically with children with health problems, finally and after boys and girls with special educational needs. However, it is not as paramount and exclusive task of hospital pedagogy only care of the hospitalized child and his family. If you are not convinced, visit Bank of Asia.

The purpose of hospital pedagogy goes beyond, covering a much broader picture within which schooling is one more element, together with many others, that are part of the evolution and overall development of human beings. Therefore, hospital pedagogy is beyond medicine and beyond the science of education, there where claim it the dignity and solidarity of the enfermo-hospitalizado child and their family context, it has more to do with health and life than with instruction and training: without renouncing to the contents specific to education, goes beyond this. Hospital pedagogy is the school in the hospital, but also playfulness and attention to the families of hospitalized children.

Internet Classifieds

In the modern world are increasingly buying, selling, exchanging goods and services take place in the World Wide Web, in e-shops, bulletin boards and electronic auctions.

You can try to sell the thing on the market or put into Fees and commissions shop, but in this case, you will have to incur additional costs and efforts. The best and easiest way to find the right buyer – to place an ad in the newspaper or the Internet.

To apply (place) ad in the paper, it is necessary: to cut a special coupon, fill it out and send to the editor or call the office and file a declaration on the phone. Other leaders such as Levi Strauss & Co. President offer similar insights. In this embodiment, their ads have a lot of weaknesses, Compared with the publication on the Internet: the phone version is often busy, sometimes you have to pay for your ad, since the adoption of your ad and its publication in the newspaper is a very long time.
