No wheels no car and who is currently the wheel without tires? Who among us has wondered where it came from a modern automobile tire? The world's first automobile tire made and patented by Robert William Thomson, back in 1846. In Pat was presented the design of the invention, as well as the present description of the materials for the manufacture of tires. It was to consist of two parts: the outer coating and a camera. Exterior coating consisted of pieces of Skin, joined by rivets, and the camera is made of several layers of canvas, with special impregnation. After testing tires were marked: coach buses with more comfortable, silent and easy. But after the death of Thomson's invention was forgotten, although all samples of the "air wheels" are preserved. In 1888, John Dunlop Thomson revived the idea. That his name is known worldwide as the name of the author and creator of the pneumatic tire.

Top of this invention is dated 1887, when John decided to put on his son's tricycle hoops with a hose, pumped up with air. The advantages of pneumatic tires have been evaluated in a short time, and their development began with a small company, "pneumatic tire and Bout agency for the sale of bicycles. " To date, Dunlop one of the largest firms in manufacturing tires. Chald Kingstn Ueltch in 1890, proposed to insert into the edge of tire wire rings and separate the chamber from the tire. A Frenchman and Englishman Diderot Bartlett came up with ways of mounting and dismounting tires. French Andre and Edouard Michelin – the first to use pneumatic tires on cars. A lot of time and improvements to a pneumatic tire molded rubber replaced.

During the First World War began the development of truck tires, the pioneers in this field were Americans. Then there are large firms that produce tires in bulk. Many of these firms still exist. This, for example: 'Michelin' in France, 'Dunlop' in England, 'Pirelli' in Italy. In the mid-50s of the twentieth century came new developments in the design of the tires. Firm "Michelin" offered to insert the hard times in the bus, it consisted of layers of metal cords. These tires are called radial. In the late 50s has been paid attention to tires, which were to provide high coupling properties and high durability. In the 60 years has been on developing low-profile tires, and in 70 years there is a transition of cars on radial tires, which increases safety and driving economy fuel. The main material for production of tires is rubber, which is made from synthetic and natural rubber and cord. Cord fabric made of polymer and textile yarns, as well as from metal cord. Bus consists of: projector skeleton belt layers, and the side of the board. In today's world is more than one billion tires annually, the industry is the production of tires is a priority for many states. Yet, car without tires in today's world of comfort, can not exist.

Talk about what ringtones, how do they work in the mobile phone and how they moved from there PC's hard drive or other media, I think it makes no sense. Proceed straight to the point. Offered the option to create ringtones by extracting of audio or video sound track with a PC and a little creative programs. 1. Create ringtones from audio files. To copy a specific part of the audio file into a separate file (the future ringtone), in my opinion, best tool is the Nero WaveEditor (thanks to the support of all popular formats, and wide opportunities), part of the paid software package Nero (). For this purpose, suitable as a free utility mp3DirectCut (), but in this If the startup file should be formatted as MP3. How to work with these programs is similar to (the article with pictures here): – Start Nero WaveEditor or mp3DirectCut; – open the startup file (in the "File" menu, select "Open …"); – press click "Play All" (for Nero WaveEditor), or "Start" (for mp3DirectCut); – listening, we determine from which part of the file will create a ringtone and its location on the primary spektogramme file – select the desired part spektogrammy with the mouse – remove from spektogrammy unnecessary (in "Edit" menu, select "crop") – if necessary, deploy the additional filters (in Nero WaveEditor are in the menu "Tools", "Effects," "Better," in mp3DirectCut – in "Edit" menu ) – Listened result, if necessary – to make changes to the above settings – save the future ringtone (in the "File" menu, select "Save As" to Nero WaveEditor or "Save All" to mp3DirectCut), indicating the storage location, The name and format the new file.

mp3DirectCut allows you to save files only in MP3, which is supported by an absolute majority of mobile phones. But if necessary, ringtone can be converted into another format using Aimp2 () or other programs. 2. Create ringtones from audio video also can be made in the above scheme. But this is first necessary to get the startup file using the program VirtualDub (see instructions here- .) VirtualDub to extract audio from video file in WAV, therefore, before the creation of her rintona with mp3DirectCut, you must convert to MP3, for example, when using Aimp2.

The importance of the System Administrator role has long been recognized, a good specialist – at a premium. Sysadmin taxis computers, and therefore the people, information, and, most importantly, the reputation of the company. Correspondingly, it responsibility. Drop service on the server, the virus in the network or the Internet may faint for a long time to paralyze the work of office and "stained" the reputation of the company. The main thing – the system works. Today in the arsenal of a sysadmin There are many programs for system administrators, both domestic and many foreign manufacturers over. "Friends", by the way, often many times cheaper, "gourmet" colleagues and is not inferior to them in the technical features and capabilities. Which programs are gentlemanly set sysadmin? It should come up to the administrator of problems: 1.

First of all, among the programs for system administrators this set must be present tool to monitor your network to detect problems with network equipment. This includes the monitoring of ports, protocols, servers, etc. These measures are intended not only to help respond quickly to equipment failure, "drop" server, but also to prevent unauthorized connections to the network, in time to identify the action of malicious software or viruses, and more. 2. Program for system administrators to solve the problem of hardware inventory. One of the functions is a system administrator control over the "iron" of the organization, supervision of his condition. Permanent computer inventory allows time to register the loss of equipment or its replacement for the older and to make the necessary upgrades.

The reader is watching developments in this area may remember him from China National OS RedFlag, based on Linux – but it is a single example, the transition from the Chinese is not over, and goes on RedFlag the whole country, and not a single education system. For concerns about the school budgets will let you know that There are numerous discounts on bulk purchases as Windows, and the academic license. And what prevents the State to order the light version of the OS? Not all functions 'WINDOWS' needs in the educational process, we can remove them and reduce price. And instead of MS Office to use the free counterparts – text-formatting functions are the same everywhere, but the student will be familiar with the common platform for document and information exchange. Nobody and nothing prevents a specialized school with embedded OS distribution in the installer training programs and materials. When the state thinks about the need to give up information and a general dependence national platform, and then have to deal with the universal teaching of the relevant educational material, and are more logical to examine the reality and the future in the form of Linux – perhaps in the form of an optional course for those who wish. Of course, everyone knows the phrase Linux is designed for the network, like a bird for flight" – the most romantic part of the whole computer, but at school we are preparing people who should be able to apply their skills to an already existing situation, and the use of software applications for them a higher priority than the operation of networks – and network engineers, system administrators will prepare in high school. .

The next step is milling the part: to give relief detail on the surface of the milled and edge. MDF is suitable for milling any equipment – from manual mill to CNC machining centers. In the production of standard software facades can do milling machine copier copiers with a set of (Made on CNC milling machine), on which the milling. Maximum performance and reduce the cost of milling cycle makes the sharing of the CNC machine and lathe-duplicating machines. The determining factor is the total length of milling blanks.

The total length of the inner milling Raised panels (Rfilenki) will depend on the decoration of the facade (with its production planning can be taken at the average level of approximately 75% of the perimeter of the facades). Thus, the time required for milling of the total facade T = (L / vn + Tvo) / Quispe, where L – total length of the milling of all facades; vn – feed rate at milling. When milling MDF feed rate can be as follows: 4-15 m / min depending on the diameter cutters; GUT – the time of auxiliary operations change tools change blanks. This time depends on the type processing center and is approximately 15% of the normal time of milling, Quispe – utilization of working time, usually 0.8. Milling at the site with additional equipment is also aspirated plant with capacity of 7000 m3 / h. At subsequent stages of the production technology is different depending on how the facade facing.
