The Requirements

Prominent scientists, AM Ampere, Yakobi, MO Dolivo-Dobrovolsky, Tesla, AG Stoletov and others known in the history of electrical engineering for its large research and discoveries have also played a large role in creating the first practical designs electrical measuring instruments. Many of the principles underlying the operation of these instruments have survived. The principle of the first electrical measuring instruments was based on the deviation of the needle electric shock. On the basis of this phenomenon Austrian physicist Igor X. Shveyggerom in 1820, was created by current indicator – ‘multiplier’. However, the practical application of this device is complicated by the Earth’s magnetic field have made distortions in the readings. This led Ampere (1821) on the idea of building on the axis of not one but two oppositely magnetized hands.

Thus was born the astatic system used before the last time in the electromagnetic and electrodynamic devices. Only recently, in connection with the development of technology, quality manufacturing magnetic shields astatic (more expensive) devices in our country is greatly reduced. In the 30s of XIX century. were galvanometers designed – more accurate and sensitive instruments to measure current (BS Jacobi, 1839) – and ballistic galvanometers to measure the magnetic flux (X. E.

Land, 1832). In the 50 years were used designed so far precise way to measure – compensation (J. Pogue gendorf, 1841) and bridge (C. Winston, 1843), later – Ballistic (AG Stoletov, 1878).

World Energy

Thursday, 13. October 2011

Since no other scientific problem does not attract such attention, as this problem, and in particular the upcoming climate change. It is believed that the main reason for this change is energy, and energy under means any area of human activity related to energy production and consumption. A significant (78% in 2001) of energy consumption is provided by energy released from fossil fossil fuels (oil, coal and gas), which in turn leads to the release into the atmosphere of carbon dioxide (CO2), which has the ability to keep the Earth reflected solar radiation. As a result of accumulation of CO2 and other polyatomic gases, among which the most significant are methane (CH4) and nitrous oxide (NO2), is heated the Earth's atmosphere. This phenomenon is called the greenhouse effect. So, we proposed scheme is simple: people burning fossil fuels, resulting in a warming climate, which could end in disaster.

It follows a recipe to avoid this risk: reduce emissions of carbon dioxide, naturally, at the expense of reductions in consumption of fossil fuels. This simplified approach is already causing real harm to the global economy and can deliver a fatal blow to the economy of those countries that have not yet reached the required for completion of the industrial stage of development of energy consumption, including Russia. The reality is much more complicated. In addition to the greenhouse effect, responsibility for which, of course, rests largely on energy, the planet's climate is influenced a number of natural causes, one of the most important of which include solar activity, volcanic activity, the parameters of the orbit of the Earth, oscillations in the system Atmosphere-Ocean. The correct analysis of the problem coming climate changes and their consequences is possible only in the light of all factors.

In this case, of course, need to be made as clear in the question of how to behave world energy consumption in the near future, whether or not humanity should establish stringent self-restraint in the consumption of energy in order to avoid the catastrophe of global warming. Common classification divides the sources of primary energy in the commercial and noncommercial. World Energy in general throughout the industrial phase of development of society is based primarily on commercial energy resources (more than 90% of total energy consumption in 2001). Although it should be noted that there is a group of countries (the equatorial zone of Africa, Southeast Asia), the large population which maintains its exist almost exclusively by non-commercial energy sources. World Energy, 50s, 60s and early 70s of XX century. characterized by extremely rapid growth in consumption of commercial energy (average growth rate of more than 5%) that the annual rate of growth of world population obnovlyaetsya Our site each day. We look forward to your participation in the development of the site 'Energy and Industry of Russia', with pleasure place your books, news, drawings, journals, term papers, articles, training materials, etc.

Japanese Style

Sunday, 9. October 2011

Do not forget the extra lighting balcony. This may be a floor lamp, wall sconce or bronze. It all depends on the style of the interior, which is sustained clearance of balcony. A small fountain or decorative composition in the style of a Japanese rock garden, give your balcony absolutely unique look and charm. If you wish to lodge interior did not match the style of the situation the entire apartment, then to separate the loggia of the room, for example, thick curtains.

If the large balcony doors (on all the wall) and glass, the balcony is desirable to make one design style to the room, as if continuing the it. Verandas often are attached to a suburban home or cottage. Very beautiful veranda, if its walls are fully glazed. Also will look stylish veranda with a combination of wood and glass. When space permits, on the veranda can provide a dining table for the whole family, sofa, folding chairs or chaise lounges. For the best porch wicker furniture or folding against the background that will look great Sansevera and Chlorophytum.

Well, if you love contemporary style, multi-colored plastic furniture in combination with bright umbrellas – that's what you need. When making a porch can be used a variety of design decisions: to make it to the Absolutely Africa, in the classical style, to devote any historical era or a modern design. It all depends on your desires, tastes and budget. Patios, as loggias and balconies have become part of residential architecture in Italy during the Renaissance. In those days, the palaces of noble people for safety and security were built like fortresses and were closed. As a result of Architectural building courtyard was obtained, which spent most of the time, people living in the palace. After a while, started to decorate patios gazebos, flowers and sculptures. Then came the install benches and tables, and patios have become a kind of recreation. They are still very popular, especially in countries with warm climates. In all the southern countries, the patio – is not only mandatory component of the home, but part of the culture of this nation. In each country, the patio has its own name. Patio is a sort of lounge and reception in the open air, lined with palm trees, laurel, yucca, citrus, pomegranate, oleander, and of course, numerous varieties of roses. Furniture usually is a different type of deck chairs, rocking chairs, chaise lounges, made of wood, plastic or wicker. Special attention is paid to a patio was cool. The hosts have great pleasure in spending time in comfortable and cool courtyards of their own or with guests. In our band, the courtyards are the privilege of country houses and cottages. They can be used for entertaining and privacy. Patio – a place where you can spend time with family, and you can relax or sunbathe myself. The ideal would be a patio, which Located along the walls of the cottage. It is advisable to plant yard in such species of shrubs and flowers, that he was buried in flowers and greens from early spring until late autumn. And you can create a corner of the eastern garden on the bank of a small an artificial pond to lay out a number of beautiful stones and planted rhododendrons and maples krasnolistny. If you want the patio looked particularly harmonious and beautiful, you can ask for help professional designers.
