Information Technology

In today's information world, we can not imagine my life without the Internet global web. He also firmly entrenched in our everyday life as a phone or TV. If you think about all what – or 6 – 7 years ago, the Internet was quite expensive, and when it came to using just a huge phone bill. Now everything has changed, Internet providers compete for customers on the contrary, and no-limit "consumer" is now available online at costs about 400 rubles. Today, more and more popular acquires mobile Internet, not only that every phone has long been established ICQ client and browser, so now, and a wide range of USB modems, which can be taken almost anywhere. Of course, the speed they have is small, and 3 G operators who promise not likely to be so fast, but still, it is worth noting convenience in their use and true mobility.

But here arises a question – How online communication replaces us live communication, and whether it is right? Here is an example, two girls at the university go down the hallway after the steam and socialize, no one tells the second: "Why are you still here? I'll OpenID such a funny movie took off! ". The question arises – is it really impossible to talk here and now than in the notorious social networks? and go see a movie together? Would not this tendency to disappear live communication in general? After all, today, many schools have moved to the remote learned to work well enough to remotely, sitting at home in front of a computer, you can communicate in social networks and clients learn through specialized sites and forums. On the other hand, such communication dictates the rhythm of modern life, we often sit down and eat once, to say nothing about communication. But the man a social being, he needs to discuss and learn new things, meet new people. With these objectives and copes just fine global network. But what gives us such a passive communication? After all, sometimes we judge knew only through the pages of Friendster, not even bothering to write about them. We become superficial. Perhaps, even, it is probably neither good nor bad, it must be taken as a given the new time.

Previously, went to the cartage, and wrote long letters. AND news could be considered an event and a year ago. Now no one will go on horseback, for example, from Yekaterinburg to Moscow, only because that aircraft impoverish the feeling of traveling, why spend more on the way months, if after a few hours you can already reach your destination? Also, have almost disappeared from our life letters written by hand, they were only for official messages or for an unusual interesting dialogue. Because of the progress of mankind, probably, will have to lose something. Apparently the world is moving to a particular dystopia described in the books of writers of the twentieth century. We all live in glass houses, or house with screens instead of walls, and get the pink coupons for certain purposes, as in Zamyatinskom "We". Reaches such a point of absurdity of humanity, of course, do not know, time will put everything in its place.

Car Wash

This very expensive! Washes closed-loop water circulation used the same water once drenched the system and a permanent filter. This water is changed once a month, two, three – depending on the intensity of work, ie from mashinopotoka. In this case, change the filters in the complex treatment system. The cost of such replacement is around 2000 USD. (450 USD – the removal of water assenizatorskoy machine, 500-700 UAH – to bring new clean water 500-700 grn – replacement filters). Car washes with a closed cycle is becoming more and more popular in recent years.

The main advantage – a car wash can be supplied even in the open field, it would be electricity. Water, once delivered, then times two months have changed and you do not need a contract with gorvodokanalom do not need to initially pass a huge waste of time with the licensing documentation ecologists to drain water out of sewers, do not bother you check environmentalists, etc. And "Pull" water and drain into the nearest sewer is not needed. But plumbing and project documentation on it are not cheap. With regard to price, the equipment for car wash systems with closed cycle of Ukrainian production is 18-20 thousand UAH. Now about the advantages and disadvantages.

Of course, the usual non-contact car wash – the most expensive for its owner and the client. For reference. Why do non-contact? Because when the car is washed with high pressure, people do not touch him. But this "contactless" very conditional, because after a hit by dirt from the machine, hand applied shampoo, hand car washes his hands and wiped dry with the same, ie "In contact". Car Wash with the closed cycle is cheaper for everyone. It should be noted experts in car wash say: wash cars at the car wash closed-loop inferior in quality to conventional cleaning. Ie the water has filtered and the body are slightly dirty divorce. We have repeatedly attempted to refute this claim themselves out of town for such a car wash. There were no divorces! All good clean! In fairness it should be noted that the owners of car washes with a closed cycle often illegally poured water down the drain and actually washing machine tap water, not filtered. Thus, it is difficult to say which water had washed cars. We in turn hope you become an owner its profitable car washes and their own experience to ensure the validity of our findings! 21.08.09

Choose Match Hydraulic Accumulator

Hydraulic accumulator – a receptacle that is designed for energy storage, accumulation of fluid damping water hammer, vibration, shock, pulsation and mechanical impulses maintaining a fixed value of pressure, emergency management. In most hydraulic actuators are used hydropneumatic accumulators with separator media. On design features (Execution) separator accumulators are divided into the balloon, diaphragm and piston. By proper choice of the hydraulic accumulator can choose a less powerful pump that will reduce costs hydraulic unit. For the calculation and selection of the accumulator is necessary to determine how much to accumulate fluid. To do this you need to know timeline of the equipment, which will mounted hydraulic unit. Based on the timeline of work are determined by the peaks of power consumption (fluid flow). Many sequence diagram of the various equipment the maximum power hydraulic unit is needed on a small time interval of the cycle.

If such systems are used Hydropneumatic, we can reduce the pump flow. Pump for the cycle time should be slightly more than the total consumption of fluid during the cycle. In this case, the slow movements of the executive bodies, hydraulic fluid fills the accumulator and, if necessary acceleration of the difference between the required flow rate and pump flow compensated by the accumulator. Positive aspects of hydro-pneumatic accumulators: the use of small pumps, reducing the heat systems and others deserve special attention gidroakkumulyatornye stations are widely used in industrial process equipment, which has a continuous cycle of work. This production equipment steel mills, machinery for pulp and paper industry and others. The main advantages of batteries, is that thanks to them, you can upgrade old equipment and make changes hydraulic parameters, without changing the hydraulic circuit. Hydraulic accumulators save electricity costs in production and is a reliable assistant in case of accidents at work. In the event of an accident they protect the well and other hydraulic equipment from unnecessary wear and ensure safety of work in production.
