Treasury Prices

The growth trend in electricity prices seen throughout the world, and expected liberalization of the Russian energy market in 2012 may contribute to higher growth of prices on the energy market. Thus internal gas prices are expected to increase by more than 25% per year, starting next year. As a result, by 2015 in the country, they can grow more than fourfold. Due to the fact that 40% of all electricity produced by gas, the effect of rising prices for gas at the power market will be very important. Now electricity is very cheap in Russia: the Nordic power market NordPool wholesale prices for electricity and a half times higher than those in European Russia, in Western Europe, electricity prices twice as high in Italy – in four. Abroad in the development of energy-saving subjects invested fortunes.

In China in 2006 adopted a large-scale program to support private business engaged in the development of led projects, it would cost the Treasury at $ 754 million. There have calculated: If you change only one third of the country's lamps and fixtures, will be spared the power that produces the largest npp in the world. Worth it. In the U.S., a similar program until 2011, the Government allocates about $ 1 billion. We were on such investments represent only a dream. And despite the fact that the standard calculation, we consider only the direct savings, and set of proxy indicators, such as reducing energy shortages, the decline in new construction, reducing the consumption of cables and wires, etc., give the effect that actually reduces the 2-3-year-old payback period of led lamps, at least in half. Macroeconomic benefits of led lighting: 1.

Organometallic Epitaxy

18. What determines the service life of LEDs? It is believed that the LEDs are extremely durable. But it's not quite true. The larger current is passed through the led during his service, the higher the temperature and the faster the aging occurs. Therefore, the lifetime of power LEDs is shorter than that of low-power signal, and now stands at 20 – 50 thousand hours. Aging is expressed primarily in the reduction of brightness.

When the brightness reduced by 30% or half of the led must be changed. 19. 'Port' is the color of the led over time? The aging of the led is connected not only with a decrease in its brightness, but with a change in color. There are currently no standards which would allow to quantify the change of color LEDs in the aging process and compare with other sources. 20. Not bad for a led for the human eye? The emission spectrum of the led close to monochromatic, what it's fundamental difference from the spectrum of the sun or incandescent lamps. Is this good or bad – is not known for sure, because as far as I know, serious research in this area never carried out.

There are no data on the harmful effects of LEDs on the human eye is missing. 21. Which of today, there are manufacturing technology of LEDs and led modules? With regard to crystal growth, then basic technology – Organometallic Epitaxy. For this process requires especially pure gases. In the modern facilities provided for automation and control of gases, their separate threads, fine-tuning gas temperature and substrates.

A New Method For Measuring Transpiration In Tree Trunks

L. Urgench State University A new method for measuring transpiration in tree trunks in the soil and climatic conditions of the region method described in this paper is based on thermal sensors dissipation. Sensors directly measure the rate of xylem sap, which can be correlated to the transpiration of trees calculated on unit area of active xylem. The principle of this method was developed by Dr. Andr Granierom in France and was widely accepted by the research community since 1996.

Xylem sap flow in plant magnified under conditions of intense transpiration when stomata are open. At a low intensity transpiration is low. The study used a relatively new method, are widely used abroad, which measures the movement of the active xylem. This simple method is ideal for the study of transpiration mature trees. In in Uzbekistan, this method is used for the first time.

Sensors of heat dissipation are two needles mounted directly on the depth of the active xylem. The method is based measuring differences in temperature (dT) between the heated upper and lower non-heated needle tip. With the use of controlled, well-known voltage, the upper needle continuously heated to a temperature of about 80C above around. With the passage of xylem sap along these needles, heated upper needle is cooled and the fixed temperature difference between the needles. If sap flow intensity, the difference in temperature between the two needles small, since heat flows from the top of the needle quickly dissipate. When sap flow is weak or close to zero, recorded the maximum difference in temperature or (dTmah).

Night Vision Cameras

Camcorder night vision lets you see the intruders at any time of day. If you intend to install a home surveillance system, the use of "night" cameras a good idea, because you can to monitor the situation during the night time of danger. As in the case of video surveillance cameras daylight, night vision cameras to send image on the video recorder or computer on which they are displayed on the monitor, and can be recorded on the hard disk. The difference in how the camera shows a picture. The principle of operation of night vision cameras on today in the chambers, there are 2 night vision technology Night Vision.

Deployment Image This technology works by collecting a small amount of light that is even at night (at the bottom of the infrared spectrum), but invisible to the human eye. This light falling on objects, makes them mapping. Such objects are displayed in green. Thermal Imaging Thermal imaging technology uses the upper part of the infrared spectrum which shows the heat generated at things, not just their reflected light. Warm clothes (for example, the human body), generate more heat than the cooler things, like trees or houses. Display on the monitor connected to increase the camera's image usually appears in black and white.

Pedagogical Material

PRODUCTION OF PEDAGOGICAL MATERIAL FROM the USE OF the TIC Karina Amorim Pear tree UAB? Federal university of Juiz De Fora Very if comes arguing regarding the use of the TIC as didactic resource and as all the proportionate innovation for the technology is to our redor in almost all the actions of our day the day. Also if it has spoken very on the importance of the change in the methodologies of education, so that the TIC are inserted as didactic tool in the teach-learning process, and the obstacles so that this insertion happens of form accomplishes and functionary, mainly in the public schools, where the lack of human resources and technological is great. To the professionals of the education they lack incentives so that the professors search courses of specialization and perfectioning to deal with the new technologies. With new practical cultural the proportionate ones for the mobility offered for innumerable electronic devices, the professor who not to search to adapt it these tools will be obsolete, and will be depriving its pupils to participate actively of its proper process of construction of the knowledge, through practical autonomous worker of study and search of information. If on the other hand it is responsibility of the State to provide the public schools with technological resources capable to promote one Real and effective digital inclusion, with resources, technological tools and Internet broad band capable to reach all the pupils of a pertaining to school institution, is paper of the educator to face the reality where he is inserted and to use to advantage the minimum didactic resources that have to the disposal to transform the traditional lessons into meeting of exchange of knowledge. It is also paper of the professor to work so that the technology is its favor in this construction of the knowledge, being produced new materials that allow the pupil to create new concepts and to express themselves in different way to that the traditional school is accustomed. If it does not have to think, however, that practical and use of traditional resources must be left of side for the news technologies, but must have an adequacy to the reality of the pupils, its interests and the knowledge that if wants to acquire with the use of the TIC. The pupil can express itself in diverse ways with the aid of the technology, as for example, through videos that illustrate the boarded contents in classroom, what it stimulates the autonomy and the search for new knowledge on the part of the pupil and the professor, who must also be always intent to the new features that can be used in benefit of the ethical formation of citizen, scholars, capable to interact with the society where they are inserted of competitive form, a time that they had been prepared to deal with the joined tools in the current market of work..

Company Apple Struck First

Apple no doubt be called a phenomenon of the computer world. Another ten years, the company was on the verge of extinction, but now it's trendsetter, all the gadgets which, immediately after the right to become a bestseller. All began with the player iPod, part of the models which have already gone through the fifth reincarnation. The transition was often gradually to keep the old traditions and revolutionary radically changing the functionality and appearance. As an example can compare the sixth and fifth generation iPod nano, because they do not resemble each other superficially and functionally, the new even was seriously curtailed, the camera appears to have disappeared.

But they continue to take, to be considered very fashionable without looking with the changes. iPhone, it is generally a song, Apple broke and turned the smartphone market, making it quite different, which plays by their rules. Since the first model, in the market is always surrounded by hype, where people are willing to stand in queues for hours and pay through the nose, several times higher than the cost in stores. And no matter what then float some defects or punctures, as you loss problem network iPhone 4, users continue to sweep to the shelves. The most recent latest innovation from Apple, became the iPad, here they have managed to create a new niche of portable computers.

During the first months of the demand was so great that a plant at full capacity it could not satisfy. The number of sold iPad, exceeded several millions. But like anything special is done, put together well-known things, a large touch screen, wireless interfaces, portability, and removed the keyboard mouse. Already other companies are trying to create competition, but their share is only ten percent of the sales of Apple. It looks like Apple is not going to stop getting more of their loyal fans, and not letting the rest competitors.

Celsius Ceiling

On the Ukrainian market of finishing materials ceilings relatively recent, but already the benefits of suspended ceilings and appreciated by consumers and interior designers, and representatives of the companies-builders. AND really – all the advantages that are inherent tension ceilings, so obvious that the owners of a stretch ceiling often left very satisfied. Let’s take a closer look at the fact a number of advantages that release the suspended ceiling, among other finishes. Installing suspended ceilings only takes a few hours, with the installation runs without rearrangement of furniture and no debris. Stretch ceilings are not require special care, and if necessary can be easily removed. Practice shows that the suspended ceiling is often changed because of the desire to change the interior, rather than for other reasons.

Stretch ceilings are very strong – 1 m2 stand load equal to 100 kg. Also of note is moisture-resistant stretch ceilings. For example, if the neighbors from upstairs forget to close the valve, the ceiling will protect from flooding your apartment – within 2 days About 60 liters of water can be retained ceiling without any consequences. Stretch ceilings are environmentally friendly and safe – they do not emit harmful substances do not contain allergens that have no smell. Also very important is the fact that tension fireproof ceilings and trudnosgoraemy (have a fire safety certificate M1). Stretch ceilings significantly increase the thermal insulation of the room, which is especially important in cold winters or instability of the heating systems.

Attenuation of stretch ceilings have a positive impact on the acoustics of the room. Separately, we note that in the stretch ceilings does not settle the condensate. This allows you to easily install suspended ceilings in high humidity – in swimming pools, bathrooms, nursery, health and spa facilities. In short stretch ceiling installation technology can be described as follows: on the walls of the molding firmly fixed, then at He fastened the canvas. Then the room is heated to a temperature termopushkoy 50-60 degrees Celsius, and heated by the film becomes soft and supple making it possible to stretch the canvas. After normalization of temperature fabric forms a perfectly flat plane. In this design allows you to stretch ceiling mount any, even very sophisticated lighting systems, up to the painting of light – a special type of design based on fiber-optic systems. As for the price of a stretch ceiling, you can just take a calculator and calculate. As a result, it appears that the suspended ceiling generally cheaper than hanging, painted and wallpapered counterparts. You take into account the cost of services for the removal of old coatings from the ceiling, materials and work on leveling the ceiling, the installation and the time required for cleaning, right? That leaves a total of that tension ceiling and more profitable. As you know, everyone chooses for themselves. But usually the person wants to choose the best.

International Advice

Therefore, the related document makes this condition to have an efficient preservation. ‘ ‘ Depending on the material of which if it treats, the appropriate mechanism can be a catalogue, an inventory or some another way to register the form and the content of a collection, since its general characteristics until the different plan of suportes.’ ‘ (Ibid., P. 19) the preventive conservation is an old concept in the world of the museums, but only in last the 10 years that it started if to become recognized and organized. It requires a deep change of mentality.

Where yesterday objects were seen, today collections must be seen. Where if they saw deposits must be seen buildings. Where if it thought about days, now if it must think about years. Where if it saw a person, teams must be seen. Where if it saw an expenditure of short term, an investment of long stated period must be seen. Where if they show daily actions, programs and priorities must be seen. Preventive conservation means to assure the supervened one of the collections. (GUICHEN, 1995, p.2) the investments had passed to be redirected for programs of preventive conservation, enclosing collections in different supports.

Joan van Albada, in 1987, participating of the Annual Meeting of the International Advice of Archives, observed: The preservation requires administration, and not restoration. The good administration of archives points with respect to the organization of the quantities, and this for the preventive conservation, that includes security and adjusted planning of disasters, storage and manuscript, and access, by means of the reproduction. She still fits, to establish priorities, on a cost-benefit evaluation.

ACT Controller

The electronic controller of the current (ECT) produces a signal upon the occurrence of one of the following events: – short circuit – electrical idle (during the dry) – electrical current exceeds the rated – exceeds electrical current above the maximum allowed – failure of one or two phases – phase imbalance of current – low insulation resistance (500kOm 10% for the modification of M2, M4, M5, M8). Optional: interface with PCs, digital input, contact pre-start or alarm. Model Range POS-5 from 0,2 to 50 A, POS-10 from 0,8 to 100A POS-25 from 1,6 to 250 A POS-60 from 3 to 600 A POS-125 6 to 1250 A pos 250 from 10 to 2500 A POS-625 from 30 to 6250 and the controller works in conjunction with a control panel CP-05, which provides data read and adjust settings of the controller. Controllers POS-5-M and ACT-10-MX may use current transformers with rated currents of the secondary winding 5A. ooo SibElektroZaschita " developed and started production of products ektm which food is carried out as a variable voltage (50 420 V frequency 45 Hz 5 ) and permanent (50 600 V) voltage without the need for additional resistors (As in scr-3 and EKRM-3) and without additional switching supply leads.
