Glass-plastic pipes are produced in the line of continuous winding. This is a huge drum sizes from 400 mm to 2600 mm depending on the type of products produced at the moment the pipe. On shaping a cylindrical mandrel alternately applied components of inert and organic materials. Manufacture of composite pipe consists of three stages. In the first phase is the so-called diametroobrazuyuschaya supporting surface of the spiral metal strip, then on the resulting surface is imposed isolation tape.
Then fiberglass coils, which is wetted quality epoxy resin. So, is their first layers tube, called a liner. The first layer or liner has a size of 1.5 mm and a smooth surface. This allows the free flow of water ensures that no silt deposits on the inner surface of the pipe and prevents wear and tear the inner surface of the product. Isearch: the source for more info. The first layer is chemically resistant, does not emit any harmful substances in drinking water, not chemically reacts with the vast majority of aggressive chemical elements, including alkalis. On the liner layer by layer, like a thread on a spool, continuous coils chopped fiberglass and comes quartz sand. All this is done with continuous feeding epoxy or polyester resin. The number of layers depends on the diameter of the pipe, ring stiffness, design pressure and other indicators of the pipe.
These layers form a proper main structural element of the tube and are called bearing layer. The carrier layer gives the necessary strength characteristics of the pipe. And, finally, the familiar process scheme is the third and final layer, it has a thickness of 1 mm and is called external. How do you understand the outer layer is the protective function, protects and preserves the pipe from the external environment, including the biological effects of soil and aggressive from aggressive UV radiation at ground installation of backbone networks. The resulting tube is made of composite material is heated in a special 'stove' infrared emitters. As a result of a chemical reaction of epoxy resin and, as consequently, its cure. The materials of which formed the tube wall, forming a strong and solid composite having properties with the elastic deformation, that is, in spite of loads of soil, the dimensions of the tube remains unchanged. This effect is achieved as a result of continuous supply of epoxy resin in the process release the pipe. That neatly encapsulates all the resin components of the design, therefore, categorically ruled out the destruction of the tube in a process operation of the network or with a different exposure.
Energy conservation and energy efficiency has recently become more urgent. For their decision today use a variety of methods and systems for energy conservation. One way of solving this problem is to reduce energy consumption in the implementation of speed-controlled electric drive. However, the customer often refuses to use the drive to learn its value, and justifies its refusal to the fact that he can not go on such costs. It’s believed that isearch sees a great future in this idea. Is it cost or profitable investment? What is the effect of the introduction of the frequency converter (the inverter) and how to assess? These issues and will focus on following lines. Define some concepts: cost – expenditure of funds for current activity of the enterprise. Investment – investment funds in various asset for future revenue from them. Define the purpose of implementation of IF: Automation, Energy Conservation. Isearch understood the implications. In the context of these goals is difficult to attribute the acquisition of the drive to the paper costs, as Before the introduction of hr activities of the company which then properly implemented. By introducing the drive, we expect kakogoto effect, so we consider the introduction of hr as an investment. In turn, any investment project must have clearly defined objectives: Continued of the enterprise; Business expansion / increase in productivity, reduction of costs; Minimize risks, improving the quality. The effect of the introduction of the drive can be very versatile and should be consistent with the objectives investment project. To assess the effect you want to reply to several questions: 1.
Game of platform is the given name to one gnero of games where the player runs and jumps between platforms and obstacles, fighting against objectos enemies and they coleccionam bnus. One of the most known and spread out examples of this type of game is the Super Mrio. This gnero directamente reaches the infantile public as well as representatives of adult public young also. They are games that require a little more than time of the player, a time that the player alone obtains to continue in the game if to reach some goals, what he finishes for demanding many times a little of trainings and concentration, to arrive themselves at the end of the level and to obtain to pass all the levels to arrive at the end of the game. The series of games of known platforms more are Mrio and Sonic, but it still has other games of platform sufficiently known as Donkey Kong, Prince of Persia, Castlevania and Mega Man.
This type of games nowadays more is known in flash, therefore it requires little capacity of the computer and any person can play. She can accede to these games from many sites of games online and use to advantage of one good time vitiated to the game to finish all the levels with the biggest possible punctuation to arrive at the end of the game. In many sites it is possible to see the punctuation of other players and top will be one of the best ones can until entering in one where the classifications are sufficiently high and alone they reach the best players online. This type of games is many amused being sufficiently easy of if to be vitiated, after passing the first level alone we want to take the game until the o end. It tries all the Games Amused that the Top Online Games has to offer to you, since the popular Games of Cars until the Games of Ben 10, it exists a little of everything, it comes to know.
Managing the factory of services with the system SatNetwork the SAT the factories on watch technical frequently are seen it jeopardize in superfluous tasks that complican the work and are delaying the tasks more and more. As the factory grows and the level of repairs is greater becomes impossible to take an order without a quality tool allows that it. With the SAT system of SatNetwork (www.satnetwork.com.ar) it is possible to load spare parts in the stock, to realise movements, to enter replacements of components, to assign the models in which the same are used, to look for parts by different concepts (code, description, model, application, etc.), to sell spare parts, to organize the stock of repair manuals, to valorize stock and to revalue increasing it the values by a coefficient, to load new distributors of spare parts with its respective costs, to control several deposits at the same time, to request spare parts for a service or stock. As far as the service area it will be able: to enter repair orders, to handle to direct services and guarantees of different companies, to realise reimbursements, to accept reclamations, to enter the accessories that are given with the equipment, to agendar appointments for domiciliary visits, to arm the trip tickets of the technicians of addresses, to add notes with information for factory (the same will be presented/displayed the technician whenever it consults a repair), to control the present state of the repairs, to budget, to take sign and to invoice the service, to assign the pending tasks, you order to print them of repair and delivery of the equipment, to look for a repair by different concepts (number of order on watch, client, telephone, movable telephone, direction, series of the equipment, model, number of guarantee, factory code). The control on the clients will be total, being able to agendar them and to look for them according to name, address, locality or telephone, to handle accounts for special clients, to send mail' automatically; s or sms s with the present state of the equipment, to send to the great clients an email with the pending repairs by budget, to notify to the same the aim of the repair, to arm remitos and to invoice repairs by groups, to allow the clients to consult the state of its equipment through Internet.

The companies who if do not worry about security of the information, cultivate imperfections in its infrastructure of net degrading the confidencialidade, integrity and availability of its systems, archives and servers thus facilitating the risk to suffer a simple attack up to one total non-availability from its managemental systems. 1,1 JUSTIFICATION the process of evolution of the Systems of Information – ITSELF she parallel walked with the technologies of computer science and telecommunications. The evolution of the technology collaborated for sprouting of the computer networks and the improvement of its capacity of processing, with the sprouting of new systems that make possible greater integration of the enterprise areas. This technology it provides mobility, agility and freedom in its use. Instead of handles, modem and other half physicists stop of if getting access to the Internet and nets shared with other devices, the net without wire alone need a plate of net without wire installed in the 2 equipment and a signal opened for free use as it is the case in airports, shopping, among others (RUFINO, 2005). All this evolution made possible the integration of systems through server and computer networks with great capacity of processing of information that if became popular between people and companies, therefore currently is practically impossible to think about conectividade without the existence of computer networks.
With this the market is concentrated in one of the new and revolutionary technological trends: the communication for nets without wire (Wireless Networks). Therefore, ahead of the relevance of the subject, the nets without wire must be safe and trustworthy to the users through implementations criptografias and firewalls leaving to be an easy target for intentioned bad people as hackers. 1.2 The PROBLEM Thus, the problem generated in this study is: Of that it forms can itself be carried through a security in the nets without wire? Verifying and I understand as wireless is possible to implement solutions of security in nets to drastically reduce the vulnerabilities of the information.
A question if to worry in transmissions of data for air is the security, therefore, had been implemented to these standards the protocol to cipher the data to be transmitted, WEP (Wired Equivalent Privacy), and successively WPA (Wi-Fi Protected Access) that it corrects imperfections of its predecessor. Some programs exist to capture information of nets without wire, as the Netstumbler the Kismet, but they also can help administrators to monitor the net. The attacks the nets without wire always reach the points most vulnerable of the net that are the concentrators and the customers, in what the administrators must apply all the cabveis measures of security and always have the attention redoubled for these two elements. Word-key: Wireless nets. Security. Vulnerabilities.
Wireless earpieces are devices that allow us to listen to music without considering cables connected to the music source. But, what makes them work without cables? It continues reading to know how they work auricular wireless. Nowadays, many people use the wireless earpieces, they know as the earpieces work, but do not know on the present system of their operation. Wireless earpieces are technological gifts that allow us to listen to music without cables. They can be used in any source of music like a reproducer of CD/DVD, the television, the computer or a reproducer of mp3. Nevertheless, they are not possible to be connected directly with these sources, but they use the RF or infrared to communicate with the devices of basic station of the earpieces.
The quality of sound of the wireless earpieces depends mainly on the range in which they are effective. Simply it means that if you go away of the range of the signal of the station it bases, that will obtain a blurred exit or no sound. When these wireless earpieces were sent by the first time, they were very expensive, but as it spent the time and several companies used this technology, the price was reduced considerably. With the increasing popularity of these wireless earpieces, the companies of electronic manufacture, have thought and are working in the invention of new technologies that have improved the technologies incorporated in them, like the radio, infrared, Bluetooth, etc How auricular wireless they work? The wireless earpieces count on three devices like the transmitter, stere and earpieces. Since it is a wireless technology, it is obvious that it is not necessary to connect the wireless earpieces directly to the stereo sound equipment to listen to music. Rather the cable is necessary to connect the transmitter to the stere being connected, or in the entrance of wireless earpieces or any other type of connection of exit of audio. The transmitter is the main part of the earpieces wireless, since it does the work of the reception of signals of exit coming from the source of music and its transmission to the earpieces, that must be in specific distances of operation. The wireless technology, can use anyone of the RF or infrared to carry out the operation of the signals.
If the wireless earpieces are using the infrared technology, need to be at sight direct of the wireless transmitter without an obstruction of the walls, similar tables or other obstacles. Because the infrared technology is based totally on the light, the transmitter will not be possible to transmit the signal through solid materials, as the light cannot penetrate through the solid materials. The signals can even be received in other rooms. Nevertheless, other electronic equipment that are gotten up to a system that uses signals of common radio, like wireless telephones, can disturb the reception of the frequencies. If as much the wireless earpieces and anyone of these wireless devices are ignited at the same time, the signals sent by the transmitter would be received by both devices, and this can cause exit upheavals.
Thermal spraying of metallic coatings – is melting and causing the metal to the substrate. As application methods, and the metals themselves may be different, most importantly, that at the surface remains subtle, more resistant to corrosion and erosion than the base metal and coating. Many years of experience in the application of coatings and Spramet testing using external influence on the surface, show that this method is more effective in the long-term corrosion protection of steel than the protection of paint or poimernymi compositions. But Spramet are also an excellent foundation for anti-corrosion paint. Organic coatings deposited on surface of the iron and steel, deteriorate under the influence of podplenochnoy corrosion that occurs under cover as a result of inadequate adhesion. A thin layer of coating to prevent corrosion Spramet base, and strong links steel with organic coating. Filed under: altavista. There are many factors to corrosion, such as the nature of substances that cause corrosion, forms of corrosion, speed factor and used metals.
Sometimes minor changes in the conditions become important factor in solving the problems of corrosion. Therefore we give here only a brief description of the electrochemical corrosion of the two metals that is most important when using corrosion-resistant metallic coatings. electrochemical series of chemical elements in sea water: Anode (corrode) Magnesium Magnesium alloys Zinc Galvanized Steel Aluminum alloys Cadmium mild steel cast iron ductile iron Stainless steel (active) Lead Tin Nickel Manganese (active) Brass (brass) Copper Bronze Nickel (passive) Stainless Steel (Passive) Graphite Silver Gold Platinum Cathode (protected) For electrical connection of two different metals or metal alloys with an electrolyte, the current travels from the cathode metal anode, the anode metal and the electrolyte from the electrolyte to the cathode metal. The amount of current depends on the potential difference between two metals. Therefore, close to the potential between metals a small amount of current. In the anodic corrosion of metals is growing more rapidly than the cathode, the corrosion process is not always possible to completely stop.
The reason is that developers like on the one hand most of developments in the dvd production to reduce production costs as disk drives and drives. On the other hand, it was decided to try to get by without a cartridge designed to protect information in the case of reducing the thickness of the protective layer disc. Recall that the first disc Blu-ray format were initially packed into special cartridges precisely because of the reduction of six times the thickness of the protective layer. And only was later developed a special particularly tough coating, allowed to abandon the cartridge. All hd dvd drives are backward compatible with both dvd, and a cd. ‘Fat’ protective layer and then helped to simplify, or rather – to borrow from ‘standard’ dvd, the mechanics of the drive, as the requirements for the positioning of the laser and optical system are significantly lower than for the blu-ray. For ‘soft’ transition to the new format proposed hybrid drives.
A consumer buying a disk, has the opportunity to view it as an ordinary DVD-player, and get higher quality the same movie when you buy in the future, players hd dvd. It was proposed two options for hybrid drives. First – combo disc. This double-sided disc, with one part of which is recorded in video format, dvd, and the second – hd dvd. The second option – twin disc. This single-sided disc that can hold up to three layers, which are closer to the laser layers (one or two) can be read by a laser and red contain standard video dvd. ‘Distant’ same layers (two or one) intended to read the blue-violet laser, include hd dvd information. End of the last format war or start a new one? As we have said, 19 February 2008, Toshiba (), not Desiring to further maintain the ‘so-called next generation format war’, has officially announced the termination of work on the further development and promotion of the format hd dvd. Blu-ray won? Well, even at first glance not so simple. Isearch shares his opinions and ideas on the topic at hand. Firstly, are former “comrades” on the format – nec and Sanyo. Secondly, Toshiba promises to provide support to users already ‘involved’ in-use format. Third, and most important, research in the field storage of large volumes unabated, threatening in the near future “to make blu-ray the same rarity as well as vinyl records.” Multilayer (up to 50 layers!)
Drives to the effect of fluorescence pit, holographic media information, development of solid-state memory – and this is just technology, details of which leaked out of the laboratories. A possible transition to solid-state memory instead of optical discs is not so unlikely, because of its revolutionary spirit. This has happened more than once. Enough to remember the transition from vinyl records to laser disk or a transition from floppy disks to USB-Flash drives. High-speed solid-state memory today is already used in professional video production. This SxS pro memory cards from Sony or P2 from Panasonic, used by them in their professional hdv camcorders format. However, while these cards are too expensive and hardly overtake dvd in volume – the maximum of their capacity is 16 gb. But also the first laser discs with a diameter of 120 mm had a capacity of 650 mb, and today on the optical disk of the same area can accommodate up to 200 gb of information.
Currently, e-books no longer a novelty, but not as common as the paper counterparts. It may affect different feeling. When light hits the paper, he reflected, as if reading from the device display that in this If the matrix of translucent light to form an image and creates a different feel to which many readers are not accustomed to, with the exception of the device with electronic paper. The first in a mass use of the device came with a monochrome LCD-screens that were released in 1998, and Softbook Press NuvoMedia. Later they were modified and the device came with full color screens and advanced functionality.
The first devices are not widespread, despite the very good technical performance. The same can be said about the products of other companies to specialize in this area. Later, there were books on the basis of cholesteric liquid crystal displays, but, despite a significant increase in resolving power, and battery life proved to be little demand in connection with a long drawing of the screen and lack of illumination. In 2007, the market for electronic books has experienced growth due to the emergence of screens with the technology of electronic paper. E-paper forms an image of reflected light as ordinary paper, and can display text and graphics on indefinitely without consuming electrical energy at the same time and allowing to change the image later. Such devices can operate for several weeks during active use. But while Readers considerably inferior to smartphones and PDAs.
