Rolling Profiles Details

Pipe bending is one of the most common operations formoizmenyayuschih cold forming, which is widely used for a variety of sheet metal, rolled sections, tubes and wire for this operation is used tube bending machine. In the process of bending the metal is subjected to simultaneous action of tensile and compressive forces. On the outer side of the material in place of the bend metal fibers are stretched and their length increases, the inside of the fibers are compressed, and their length is shortened. Only the core layer or the neutral line, at the time of the fold does not undergo contraction and expansion. Length neutral axis after bending workpiece does not change. In cases where the bending stresses do not exceed the limit of elasticity, deformation will be elastic piece, and after removal, the stress will take its billet original appearance.

There is another type of bending, which provides accurate angles and radii. This so-called flexible with stretching, bending when logging in is subjected to additional tensile force with bending tool. In this case all the fibers have tensile and observed only a slight reduction in cross-sectional area, while the angle and bending radius remain unchanged. The greatest distribution in the tool bench and work practices were bending. Upon receipt of parts with very small radii of bending a risk of breaking the outer layer of the workpiece in place as a result of bending excessive for the material elongation of this layer. Increases the risk of bursting due to the presence of surface defects piece (cracks, tearing). The value of the minimum allowable bend radius depends on mechanical properties of the workpiece material, the applied bending technology and the quality of the workpiece. Parts with very small radii of curvature should be made of plastic materials or pre- expose the raw material to heat treatment – annealing.

Weatherproof Decorative

The basis for applying the decorative coating may be a wall of concrete, bricks, plasterboard, solid fiber board, particle board, all durable washable and resistant to abrasion old paint. The surface on which applied decorative plaster must be dry, clean, smooth as possible and not crumbling. Large defects need to putty. Valid shallow cracks and defects neobshirnye, not exceeding a depth of two thicknesses of deposited layers. Then, the surface should be covered with soil cementing. It must be done if the base rapidly absorbs water, such as plaster, porous, old, crumbling plaster. Decorative facade plasters – Thick cover it with a definite structure. The structure of the coating is determined by size and shape of particulate filler used tool, as well as technological methods of application.

The main advantages of their use include: – the requirements of careful preparation of several reasons reduced – high decorative properties of the coating – the plaster could be tinted in a wide range of colors – front cover have a high vapor permeability and mechanical – strength and resistance to Weatherproof – will facilitate further refurbishment of such coatings. Cover decorative plasters has finished appearance, but sometimes, to further improve performance and decorative qualities, plaster coating additionally painted. Paint the plaster coating, compared with smooth coatings require a much larger flow of paint. Decorative plaster themselves represent a significant material flow per unit area, therefore, such coatings have a high cost. Decorative facade plasters are an essential element of the external insulation systems. Choosing a plaster for the walls, the customer can be sure that you can get exactly what he expected: a designer have the opportunity to dream, to "play" with the material: to draw a picture, ornament, make a graphic figure. In order to reduce the cost of finishing and at the same time getting the color and style of interior solutions, you can trim parts of the room, alternating between the paint, plaster, mosaic and so on.

Foundation Repair Technologies

The most cost-effective foundation for building a country house is by far the foundation for technology-pile foundation TISE.Vid with monolithic reinforced-concrete grillage. The main difference between piles of IPB normal driving is an extension to its lowest chasti.Eto created by the special design of the drill, through which piles and drilled svai.Ushirenie bottom prevents heaving soils in winter push them up. Piles reinforced and filled it betonom.Posle put shuttering and poured monolithic rostverk.Shag piles, piles and reinforcement scheme grillage is calculated for each individual home on sheme.Rashod pile of concrete per-0, 12 cbm The pile has a large carrying capacity (10 tons). An additional advantage of such piles before the ordinary is the possibility to leave a foundation for the winter. Then as usual to load the pile (to build a box home) to avoid being pushed by the frost, even if the pile and laid below the depth promerzaniya.Eto a big plus when you consider that not every developer immediately find funds for the construction of the entire cycle. If we take the house project size in terms of 9h9m with one interior load-bearing wall, you will need to fill in 35 piles in increments of 1.5 m, which will take 4.2 cubic meters betona.Na grillage with a cross section 400h400mm will take another 7.2 cubic betona.Itogo -11.4 cubic meters of concrete. At the same Tape the foundation will take about 25 cubic meters of concrete, plus excavation work, plus armatura.Raznitsa in price can add up to two or three times. There is a considerable saving of both time and deneg.Rabotniki construction company ‘Phoenix Group’ to help you calculate and prepare a foundation.

Childrens Outerwear Choose

Very often, parents, planning to buy warm clothes for children have the upper light shock on the abundance of insulation, which is represented on the market today. 'What is the insulation you prefer? Which is better? What is warmer and more practical? " It an incomplete list of issues faced by every caring parent. Let's try to understand what are lagging, what are the pros and cons. In general, all those present at the moment on the market, heaters can be divided into two groups: C heaters. Thinsulate – a synthetic insulation of the new generation.

Very easy. The structure of the material is extremely thin fiber, excellent air retention. This in turn provides a good 'teplosohranenie'. Apparel Thinsulate insulation with a very easy, convenient, comfortable and warm. The material holds its shape well and has excellent ability to shape recovery after deformation.

This affects the ability of strirki: material practically does not shrink even after repeated washings. Usually wear with this insulation is of significant funds. Izosoft – One of modern insulation, which is a synthetic fiber spherical in shape. These fibers are separated by an air cavity, through which the product is excellent and keeps the heat form. If we compare izosoft with synthetic padding, the warmer the last izosoft several times. Thanks to modern progress, clothing with synthetic fillers are inexpensive, and has an excellent price / quality ratio. Topsfil – modern insulation, worked with high technology. The material is very light and airy. Due to its structure, creating the effect of 'breathing' children's clothing. Hollofayber and Fibertech – are positioned as Substitutes down. The structure of the material is a hollow fiber into a spiral. Feature of the structure is reflected in the ability of a material to recover its shape after deformation and keep the heat very well. Except addition, the materials have good moisture resistance, and 'air' structure allows for a long time to keep warm.

Information Technology

Man as part of the universe, and is a solid unit that is inextricably linked with the world of nature and society. Over a long period of global history, this relationship was relatively stable and, in some measure, predictable manner. If we consider man as energy-system in which there is a continuous process of updating the information on two levels, then we can talk about the speed of updating information in the system genetic (biological) and vnegeneticheskom (social) level. Since any periodic process can be taken as a reference, then we can talk about the reference frequency of information update on the first and second levels. For clarity, we consider the process of Fig. 4, where the upper part shows the total duration of conventional global historical process.

In order to determine the reference frequency of biological time, was selected statistics of different families, of which the normal distribution revealed that the average age of mothers at first birth is 25 years. Unit divided by the period f = 1 / (25) was taken as the reference frequency fb of biological time. One of the main characteristics of human society – the period of the life of technology in key sectors of society. In the Middle Ages during the life of technology was sometimes several hundred, and in earlier periods of history and a thousand years. But with time during the life of technology has reduced to decades. Thus we can conclude that the rate of renewal Information on the social level is not constant T = 300-150 years (currently 3-5 years, depending on the area of knowledge).

USB Flash Drive

But programs can not see the data, in this case requires laborious manual work. Digital photo recovery also depends on the data format (JPG, TIFF or RAW) and the firmware version a particular camera. Shut in flash memory is correct, use the "Safely Remove Hardware". In the FCC and other similar techniques follow the battery and turn off no earlier than the end record to the card. Mechanical breakdowns. Due to its compactness and functionality of the stick are very popular. Therefore, they are often subjected to various tests.

Level of preparedness to him at all flash drives are different. Some rather weak body, while others – mount connector USB, the third – of the PCB board is too thin, etc. Mechanical stresses create cracks and lead to a breach of contact. From bumps and falls suffered crystal. Such injuries is not hopeless. You can replace the parts, re-establish contact, to say goodbye to the data is possible only in case cracked chip memory. If you have no time to be careful with the flash drive, choose the most durable devices: a metal sealed enclosure.

Memory cards are best kept in their cases. If possible, try not to touch the flash drive inserted into the port USB. Not only can you damage it, but also to get closure. If the USB Flash Drive was in the water, especially sea, do not have "self" as the lack of drying can destroy the chances of spasenie.Elektricheskie and heat injury. Unstable power supply and discharge the static, weak protection against fluctuations voltage wiring old – all of which can cause malfunction flash, and the coincidence of adverse conditions lead to burnout of the controller and the elements of tying. And if it is wrong to connect the cable USB-port that goes from the front panel connector of the motherboard, connect the device to instantly burn up. Some plastic cases can not provide good heat and when working parts can be loaded overheat and fail, and even proplavit housing. Take care of the grounding and power quality computers. Before you connect the flash drive, touch a hand system unit. Of static and heat are well protected Flash drives in metal cases. Failure of the controller. The controller is all flash drives and many memory cards. In some situations (eg, intermittent power) the firmware is locked and unresponsive OS. In this If the device is recognized as a Generic Drive with a capacity of zero, the data in the usual way are not available. They can be considered directly from a memory chip on a special stand. Fix the fault can be achieved by restoring the firmware controller using technological tools. Must be protected from static and flow control pitaniya.Iznos memory. USB-drive is recognized, but read errors due to defects on the physical level. Flash pamyatimeet limited number of rewrites. A number of service fields file system can be rewritten with each update any of the files. It is these cells first to fail. To prevent this, use technology called "wear leveling": frequently changed data is moved within the address space of flash memory. If this does not help correct the situation can low level format with hiding defektov.Pri constant updating of data failures may begin as early as 1-2 years. For hedging try the phasing out of sticks 'experienced', or use them to store less critical data. The solution of the more serious problems, of course, best left to professionals. Take care of your flash drive, and she, in turn, will take care of your data!

Ancient Russia

Terminology Parquet – floor covering of different types of wood, stacked, ottsiklevannoe and polished, with the application of a protective layer in the form of varnishes, oils and other protective coatings. Sanding parquet – alignment surface after the installation of new flooring or removal of the upper contaminated layer (1 to 3 mm) of the old flooring. Parquet polishing – fine treatment of wooden surfaces directly under the application of varnish or other protective coverage. Floor plank (riveting, die) – the unit, specially treated wooden parts of a certain size, has tongue and groove to dock with the adjacent slats when installing parquet flooring. Groove wood flooring bar – a deepening of the longitudinal and end parts of the strap, insert the comb. Crest of the floor plank – prominence on the front and sides of the longitudinal strips to insert into the groove. The first mention of the dance floor appears even in the annals Ancient Russia since the reign of Ivan the Terrible. Of course, since the time of production technology and application of parquet significantly changed, but the floors and to this day remains the most popular floor covering. AND agree that when you see a beautiful well-packed and finished parquet, for example, various reports from the halls of the Kremlin, it is sincere admiration. Moreover, any uninitiated person in technology manufacturing and device parquet floor, of course, thinks that "it is probably as difficult, long and expensive," he fears, and assuming that he can have a beautiful wooden floors in their homes.

Stretch Film Ceilings

Represent a thin sheet (film) thickness of 0.15 mm, manufactured from high quality vinyl, which pull on the skeleton, called a baguette. On the domestic market suspended ceilings come from France and Holland. Lightweight, durable, not afraid of water, they also hide the bumps, cracks and other defects in the main ceiling. Frames are fixed on the perimeter of the room on a wall or ceiling, it can be visible or secretive, plastic or duralumin. Stretch ceilings produce 150 colors and shades, different textures: matte, glossy, allowing to achieve the effect of specular reflection and thus visually expand the room, marble, suede, velvet, satin, metallic, perforated. Design features of this coating can install them in a room of any configuration, "embrace" the ceiling column create a multilevel ceiling, any geometric shape that is achieved with using split baguettes. Between the suspended ceiling and the ceiling you can put a variety of technical devices: ventilators, air conditioning and lighting.

Guaranteed excellent quality stitches and designs for the next 10 years. From the rolls of a width of 1,5 m (1,6 m in the extended form) make the cut with an allowance for stretch. Canvases are welded together, the contour of welded harpoon – fasteners canvas. On patent ceilings visible thin line interface, it is invisible to the mat. Technology ceiling installation is as follows. On the wall discourage horizontal line through it install aluminum or plastic molding.

Reinforce it with dowels and screws. If ordered recessed fixtures, they set the lock. The canvas is hung on the suspension, heated gas generator (heat gun) and pull around the perimeter of the room. After cooling facilities film is compressed and the ceiling turns out perfectly smooth, without any wrinkles. In the gap between the wall and ceiling, equal to 8 mm, insert a special filler profile. In the right places pierce holes reinforce reinforcing ring and install fixtures. Single fabric tightened 60m2 ceiling if the room is larger, the stretch ribs, to which the film is also stretched out. Stretch ceilings can be cleaned using any detergent, but only with a soft cloth, brush can scratch or even break, because the film is set . Stretch ceilings are not afraid of leaks – they can withstand a fairly large body of water (up to 100 l / m 2 ceiling). Drain it by opening a hole for the lamp. If the built-in fixtures not, the experts of the firm, establishing a ceiling, the ceiling will release angle, release the water, and then attach the ceiling in place. With tension ceilings You can use any type of lighting, but the power of the built-in halogen or incandescent impose restrictions: no more than incandescent lamps 60W, halogen lamps – 35 Tues Fixtures attached to a main ceiling.

Math Skills

With the development of mathematical skills of the students with the interaction of experience, education and maturity, the curricular emphasis moves from relatively simple to more complex tasks. In general, the cognitive complexity of tasks increases cognitive domain to the next. It is intended to allow a progression from the knowledge of a fact, procedure or concept to use that knowledge to solve a problem and from the use of that knowledge in uncomplicated situations the ability to engage in systematic reasoning (transit of Content different cognitive demands). The following sections continue to describe the behaviors, skills and abilities of the students used in the definition of each cognitive domain with respect to general skills expected of the students. I. KNOWLEDGE OF THE FACTS AND PROCEDURES The ease of use of mathematics or reasoning about mathematical situations depends primarily on mathematical knowledge. The more relevant knowledge that a school can remember, the greater its potential to address a wide range of situations posed a problem. Without access to a knowledge base that enables easily remember the language and basic facts and conventions of numbers, the symbolic representation and spatial relationships, the school would be impossible mathematical thinking endowed with purpose. The events encompass the factual knowledge which is the basic language of mathematics and the mathematical properties and essential facts that form the foundation of mathematical thinking. Procedures form a bridge between Basic knowledge and use of mathematics to solve common problems, especially those with which many people in their daily lives.

Pasting Wallpaper

Desktop has long been firmly on the palm as widely used interior material. Wallpaper manufacturers afraid to lag behind competitors are constantly improving their technology and apply new materials that raise the property of wallpaper on a new level. When choosing wallpaper can not be guided only by appearance, be sure to take into account their properties. You'll encounter with an assortment of different types and characteristics oboev.Pered pasting wallpaper you have to prepare the surface, ie remove starye.Budet easier if you moisten them with water and soak up the pressure, clear steel spatula. Further, if there is a whitewash then wash it off. You also need to pro primed wall, behind the putty where required and when dry you can get down to business. Clay in the stores today are also presented in a wide range, today there are compounds with different properties, moisture-resistant, opposing the development of mold and mildew and most importantly easy cooked in cold water using a mixer. Only necessarily aware that the label indicates to what exactly the type of wallpaper they podhodyat.Pri to work is important to close windows and doors.

If there is an edge then glue should begin from the window.
