For a long time as a shut-off and control valves used valves and valves. In this case, very often it was the valves and valves made of cast iron and very high quality. Many professionals who work in the field of installation and operation of various systems of heating and water, are well acquainted with the problems encountered when used as a multipurpose valves traditional valves – the need for an annual audit for the packing and cleaning rings sealing discs from dirt, the complexity of the emergency line shutdown in emergency cases, a lack of integrity, a high percentage of failures due to a drop jaws or broken bolts. Besides all this, catches have large dimensions and relatively heavy weight. Today is a good alternative to conventional valves and valve – Ball cranes. Ball valves, non-ferrous metals with a threaded connection to the pipeline is already widely used in plumbing, heating, gas, heat and power to individual nodes, and industrial facilities. To objects of power (CHP, rts, boilers, chp, the heat network pipelines), and numerous industrial applications where high requirements for serviceability, in accordance with applicable regulatory requirements (snip, etc.) the use of fittings made of nonferrous metals (including ball valves) with Ring Joint connection to the pipeline is limited. Valves and fittings made of nonferrous metals, not recommended for use on pipelines with a diameter greater than 50 mm, operating at high temperatures and pressures, since the strength characteristics of the case and bolting significantly lower than that of the armature steel and cast iron with flanged connection to the pipeline and the weld.

Types Of Varnish

Linseed oil – it's processed vegetable oils. They are used to produce coatings on their own or mixed with color pigments and resins. For linseed oil also include solutions of alkyd resins and some other organic compounds. Natural drying oils are made from recycled vegetable oils and substances that speed up their drying – driers. The composition of semi-subsistence and artificial drying oils include, in addition, organic solvents, which regulate the viscosity of the varnish. The solvents used primarily petrol-solvent, turpentine. Processing of vegetable oils in the varnish is in their cooking, and the introduction of driers.

Vegetable oils are not suitable for cooking oil paints and varnishes. Drying them on too long, and produced films have insufficient water resistance and lower mechanical properties. When heated vegetable oils (with desiccant) is in the process of polymerization of the molecules of oil, formed high molecular weight compounds, which provide an oil film, high moisture resistance and improved mechanical properties. Semi-subsistence varnishes are made from vegetable oils, which are natural plant oils subjected to even more dramatic chemical changes as a result of the strong heat treatment or adding chemicals that cause transesterification of oil molecules. Artificial drying oils – is the third group of drying oils, which are derived from synthetic film-forming substances.

They are often called synthetic, which is not entirely true, since most of the raw materials for them to receive not through the synthesis of elements, and waste treatment chemical industry. Natural drying oils (flax and hemp). Contain no solvents. Their produce almost exclusively – from drying vegetable oils, mainly flax and hemp. Linseed varnish have a light yellow color and are suitable for making white and light colored oil paints. Color hemp drying oil is much darker.

Thailand Country Woods

Thailand is a country of forests, shrub-studded grasslands, marshes and wetlands dotted with lotuses and water lilies. Since the mid-20th century, the total area covered by forests has declined from more than half to less than one-third. Forest Clearing for agriculture (including plantations), excessive logging, and poor management are the main causes of this decline. The forests consist mainly of hardwoods such as teak and timber and resin production of trees in the family. As elsewhere in Southeast Asia, bamboo, palms, rattan, and many species of ferns are common. Where forests have been logged and replanted not, of medium height grass and rose bushes, which often restricts the use of land for agriculture. Lotuses and water lilies dot most ponds and marshes throughout the country. Thais have traditionally used water buffalo, oxen, horses and elephants for plowing and harrowing the fields, transporting goods and people, and move heavy objects.

In the 1980s, however, the draft animals were replaced by machines, and, except in remote areas, the animals used for transportation were replaced by motorcycles, trucks, cars and buses. The demand for work elephants are almost completely disappeared after the ban on logging in 1989, and domestic elephants were involved in the tourism industry. Rapid deforestation in Combined with the marked increase in demand for exotic animals were disastrous for wildlife. Rhinos and tapirs, as in many parts of the country, but it all vanished, like herds of wild elephants. A similar fate befell the gibbons and some species of monkeys and birds. Although serious efforts have been made to prevent the illegal sale of endangered species, they have met with only limited success. Like other legislation on protection, which has a long history in Thailand, the laws were difficult to implement and achieve.

Sciences Uranium

The same is the fact that before a note on a new radioactive substance in the composition of uraninite "* appeared in the Proceedings of the Academy of Sciences, Marie had sent the manuscript to his homeland, to Joseph Bogusskomu, head of the laboratory of the Museum of Industry and Agriculture, which began its first scientific experiments. The report was published in the Swialto, a monthly illustrated review, almost simultaneously with the publication in Paris. " * Mineral uranium, its composition UO2. Curies explored different uranium-bearing minerals. Why radium and polonium not? In fact, why radium and polonium are not brought the Curies worldwide fame? After the first element, open them, there was an element number 84. After a year they had no doubt that pitchblende contains two new element.

But these elements are allowed to know about yourself only radioactivity, and to convince everyone, and especially the chemists, that the opening does occur, it was necessary to highlight these activities, learn new elements at least in the form of individual compounds. All radioactive elements and isotopes are known, are now united in the family: the decay, the nucleus of the radioactive atom into a nucleus of another child element. All elements of the radioactive families are together in a certain equilibrium. Measured in uranium ores equilibrium ratio of uranium to polonium is 1.9 1010, and in equilibrium with a gram of radium, polonium found 0,2 mg. This means that uranium minerals radium almost 20 billion times smaller than that of uranium, and polonium in 5 thousand times smaller.


Nevertheless, assessing the situation, 48% of Omsk was told that "things are not so bad and you can live, another 43% ohmic "live hard, but you can endure, and only 5% said that they" hate our plight is no longer possible. " Men and women almost equally assess the situation. Optimism prevails in Omsk 21-30 years (66%) and 16-20 years (55%). Was found a direct correlation between the age of the respondent and the proportion of pessimistic Omsk: Omsk if among up to 40 years, the proportion of those who "suffer the plight of already impossible," was less than 4%, among Omsk 41-50 years, the answer was given 7.5% and among 51-60 years old Omsk figure was 12%. Optimists were more among the unemployed Omsk (53% among the unemployed compared to 45% among workers), with the largest share among the unemployed amounted to students, housewives and pensioners. Single unmarried respondents were slightly more optimistic than their countrymen who are married (51% and 46% respectively).

In addition, the greatest optimists were Omsk living on one (the proportion of optimists was 64%), whereas in families, consisting, for example, from 2 people share a positive-minded Omsk was 31%. Figure 1. Opinion Omsk assessment change their financial situation over the last year Figure 2. Opinion Omsk assessment changes the nature of power in the last 3-4 months More than half of Omsk (54%) believe that tough times still ahead, 13% believe that the hard times we are experiencing now, while 18% hope that all the difficulties already behind.

Civic Integration Examination

The requirements depend on the purpose of your stay in the Netherlands: work, study, family, visiting family members, for example. Certain requirements to be met regardless of your purpose of stay in Netherlands. For example, you must have a valid passport. To obtain a residence permit in many cases you will need to be tested for tuberculosis and have medical insurance. Examination on civic integration (civic integration examination) To be eligible for a temporary residence permit ('mvv'), in many cases, you will be required to pass a civic integration abroad. This exam tests your basic knowledge as Dutch, and Netherlands society.

Examination is taken in the Netherlands embassy or consulate in your country of origin or country of permanent residence before arriving in the Netherlands. All people aged 16 to 65 years who require a temporary residence permit ('mvv') and who wish to reside in the Netherlands for a long time, you will need to pass a civic integration. This includes foreign nationals who wish to start a family with someone in Netherlands or join family members already living in the Netherlands. Religious leaders such as imams or preachers who come to the Netherlands for work, also need to pass a civic integration. You do not need to take the exam for civil integration abroad, if you want to live in the Netherlands under the program 'Au-Pair', as a family member of someone with refugee status, or you make a family visit. From Foreign citizens and dependents of these members of their families who wish to reside in the Netherlands for study, medical treatment, for employment, for self-employed, or as highly skilled migrants are also not required exam for civil integration abroad. Exemption from the examination of civic integration abroad may also be made for medical grounds, there are also exceptions for people Surinamese nationality. This list is not exhaustive.

Selected Works

So that it was clear to any thinking person. This article represents another attempt to bring to people's consciousness a new correctness PRpoT to persuade my contemporaries in the necessity and usefulness go for it. 2 Speaking of the distribution of labor, Professor Kuzmin implies, of course, the Soviet PRpoT, ie distribution on the principle of equal pay for equal work (PROzRT). After the Soviet Union, where the author notes lived, probably, his life has been used primarily this principle. Since the capitalist principle of distribution (unequal pay for equal work) was rejected by the Union in full, and egalitarian principle (equal to unequal pay for work) was used, or sporadically, or in violation of PROzRT. It turns out that the title of "fairest" (humanity, I leave aside), the author criticized quote gives it PROzRT.

But still Karl Marx, "Critique of the Gotha Program" showed the injustice and the bourgeois limitations of this principle. And Lenin in "State and Revolution" fully agreed with this view of Marx. True, Marx in his "Critique" expressly formulated PROzRT, but he says there that "the individual producer receives back from society after the deductions for as long as he gives to it" (See, for example, K. Marx and F. Engels, Selected Works. In Three- ie T Z. – M., Politizdat, 1981, p. 14). And what is it, if not PROzRT? If not directly proportional dependence of the fraction obtained by the employee in private consumption, the size of the contribution of the employee. Furthermore, Marx argues PROzRT injustice in comparison with the principle of distribution according to need.

Plastic Products Manufacture

Today in the manufacture of plastic products used different structural types of molds. Each of these types of stands, depending on how the production molds were made drawing up the nest and loading chamber. Manufacture of molds – a necessary element of any production of plastic products, as they cast all its parts, or just the finished product. That is why the manufacture of molds is very important stage, because of their quality are dependent appearance and characteristics of the finished product. The main element of any mold is the matrix corresponding to a polymer for imparting the desired shape. It combines two basic element: the actual shape of the cavity and the loading chamber.

Manufacture of molds suggests that, for the manufacture of different complexity and different materials needed to apply certain shape design cavities (or decorate nests). The first type – open. In the manufacture of molds is not creating a separate loading chamber, and it is used as the decoration itself nest. As a result, the accuracy of the casting in such a mold gets low, so it can only be used for the manufacture of simple configuration and low thickness. Opposed to it – closed type. Manufacture of molds here implies Department of the loading chamber, however, it is thus a direct continuation of the issuing slot.

Manufacture of molds of this type is necessary for the production of products of complex configurations, which require high precision casting. For them, apply any plastics, including fiber. The only requirement – they must have low turnover. There is also another type – a semi-closed. It differs in that the matrix and punch made extractor edge (also called this type of drawing up the nest with overflow). Manufacture of molds such construction is used more often than others, it provides accurate casting products of different configuration. The production used powdered and fibrous plastic low yield.


The idea is that every product manufactured and sold should be marked on the bill. Marking – a kind of message producer to the buyer. Unfortunately, we often illegible stalkivae6msya with "handwriting" of such messages when you do not see any possible release date or batch number, because the information was erased. Neglect the labeling can lead to disastrous results. Because of obsolete products – is a threat Health and buyer blow to the reputation of the manufacturer. Acquires special significance marking in Russia. Too often, each of us faced with substandard products. So you want to be the most awareness of the purchased goods.

Marking may pursue different functional, but the same importance on purpose. The most typical labeling – it's about time and date of issue, the long term implementation, product number and lot number. Marking may be on the package label or on the product itself. There are other types of marking – the application of trademarks, pictures, or drawing of a multi-labeling, that can actually replace the label. Increasingly we can see these marks as a logo, bar code, signs and graphic designs that protect them from fraud. With the marking can be specified and win prizes product. Labeling also protects products from counterfeits. Unusual markings distinguishes good from the line of similar products.

At a minimum, it should be clear, legible and waterproof. The process is carried thanks Markers. Speaking in simple terms, Markers – a printer that prints on the product. We have to admit that the marking equipment is, in turn, are rare. This knowledge-based equipment, so it makes sense to purchase a credible company. Marking the printer is non-contact method of application of constant or variable information about the products. Markers are universal and highly specialized. One universal device can be carried out and marking of eggs for example, labeling the package. Depending on the needs of the application or other information to program and Markers carries out its tasks. The marking must be flawless in terms of quality performance and provide detailed information. The marking must be on all products regardless of destination. It Everyone needs and goods, and the buyer and the manufacturer.

Readiness to Perform Work

The theoretical part of training in a nutshell was to ensure that their subordinates may be four stages of readiness to perform work: able – configured, can not – configured, is capable of – is not set and can not – is not configured. Depending on the stage in which the subordinate manager is obliged to apply four different approaches, combining different proportions of directiveness and support. All the approaches documented in the formulas and sealed by the author, Paul Hersey training. In the first approximation, all is simple: if, for example, the employee is capable of, but not configured, it should be motivate, not instructing. And if not, say, set up and not able to act "directive" – the principle of "you can not – teach, do not want – to make." If with the abilities and attitude of subordinates in all it was videozadachkah more or less clear, with the assessment of the adequacy of the behavior of superiors on the screen problems. For example, it was difficult to understand – explaining the operation of the computer system, zavskladom supports its employees or instructs? Nor does it quite clear – the boss, rubbing skinny Chinese girl that that sales had fallen by 12%, chastises a subordinate or so trying to help her? Controversy subsided only for dinner.

Shabby conversations on business At half-time sales training was found out a couple of fun things: two members of the business of training "dispatched" to understand the book of corporate sales training or not, and one girl, Catherine Demko, she was business manager of the company's "Organization of time." She was curious to see how work colleagues. "One of my favorite coaches – Alexander Solomatin of companies 'Mainstream' Daughter 'Ecopsy consulting'" – confessed Catherine. According to Demko, once one of his customers complained that more than a year he can not arrange a personal meeting with a potential buyer – he finished with a polite refusal.
