Wood

Finishing room log home built on a set of rules deriving from the requirements of coloring wood structure, wood protection from scratches and damage, accidental fingerprints possibility of absorption various household odors. In addition, we must remember that certain coating facilitates cleaning. Naveen Selvadurai is often mentioned in discussions such as these. Finishing materials are of two basic types: toning and protective. Tinting coatings contain substances that give shade the surface of the logs, and other ingredients that penetrate into the wood in several layers. For more information see this site: Shaw Parents. These coatings do not provide an absolutely hard surface and can be slightly sticky to the touch. If these logs are not covered by a protective composition, they can collect dust.

Protective coatings do not penetrate the tree and create a smooth surface that is clean. And the defense, and tinting compositions are based on different oils. State standards and new technologies have led to the emergence of a new generation of less toxic water-based finishes. These substances are non-combustible, do not turn yellow over time and do not emit harmful substances. They sometimes contain protective components from UV radiation and are perfect for natural tones of wood. The problem of longevity, however, is still a cause of debate among professionals, so check with your builders, that they intend to use and why.

How to paint and impregnation may have a different density, to be glossy and matte. Tips on finishing of wood: If you apply a glossy protective structure on glossy as the impregnation, the brilliance is enhanced in two ways. Before you apply any finish to the walls, take a test sample – the more the better. If you feel unsure, start with lighter colors, as it is always easier then do the wooden surface is darker than lighten it. Different types of wood no-impregnation and perceive different shading, even the same breed, but cut down or ostrugannaya a different way. In fact, color different sections of one timber can vary greatly, so it is important to apply the same method of applying the material. I consider using one hand – as a sample, and the main surface, usually for internal wall is applied three coats of finishing material. Impregnation should be used for log walls in the interior, even in those cases where you want them to look natural, just felled. The logs should be thoroughly cleaned. Rough surface and then take an additional polish, and then to have an absolutely smooth surface, apply at least two layers of topcoat. Village houses partially oshkurennyh logs also require special attention. Without the special coating remains crust will break and the tree – dark as death of surface cells. Bright continuous coating may be a good solution to the tree looked at the possibility of a natural. If the finish is correct, in two or three layers, the inner wall of the house may never be in need of repair. An exception may be the areas around windows and glass doors subject to constant and high levels of ultraviolet radiation. You also need to restore those portions of the walls that were damaged during the operation. Any moisture penetrating into the timber, destroys the paint, trying to come to the surface.

Earth Work

Graders – self-propelled machines, work equipment which is movable blade. In addition to basic equipment – the blade on the grader – set the removable working parts: a small dozer, kirkovschik for preliminary loosening dense and heavy soils, snow, cold milling and other motor grader has a hydraulic system controls the main blade, which provides its turn in terms of 360 and tilt with traction frame of up to 90 . This design allows the machine its purpose and scope: road grading and finishing the subgrade, ballast unit, gravel and sand pavement, construction of low (0.6 m) mounds of the side reserves, planning, cleaning and snow, etc. The main purpose of motor grader – profiling the road subgrade. The greater the resistance and difficult working conditions, the stronger must be the motor grader. Depending on the engine capacity and weight machines produce lightweight (up to 100 kW, 9 m), medium (100 …

150 kW, 10 … 15 m) and heavy (over 160 kW and more than 15 tonnes) graders. Light graders used for the maintenance of roads, medium-building in the road at an average density of soil, and heavy – with large volumes of excavation in dense soils and placement of road surfaces. The design of most graders standardized, it includes the main frame, pulling the frame, a turntable with a blade, engine, transmission, chassis and equipment management system. Traction power, maneuverability and stability graders characterized by a pattern of running gear. Depending on the industrial and technological requirements and conditions of use (and for this purpose, commercially available) graders with different numbers of wheels and the leading axes, as well as the control system and tilt axes of the wheels.

Wheel scheme denoted by LH5HV graders in which A – number of axles, steering, B – number of axles, B – the total number of axles. The greatest widely used motor graders, wheel scheme which 1X2X3. Ways to improve the performance of motor graders are to increase the operating speed of the machine, reducing the time for preparation, reduce lost work time and decreasing the number of passes in the same place at the expense of automatic control systems scraper blade profile. Grader-elevator – Earthmovers continuous action, developing ground or a flat disc with a knife and handed it to the dump or vehicles conveyor belt. To develop a soil knife is lowered to the ground, the motion of the machine he developed and falls off ground running on a conveyor belt. The latter raises the soil to a height of 4 m, moves in the transverse direction (in the dump or in vehicles) at a distance of about 10 m. The presence of the pipeline makes it possible to build low mounds up to 1.5 m of lateral reserves hold up to 1.5 m shallow trench. Thanks A built-in machine principle of continuous layered excavation grader, elevator has a high technical performance – more than 600 m / h. However, its implementation requires a number of stringent operational conditions: flat terrain, the lack of large (over 150 mm) stone inclusions, which can damage the disc blades, the presence of sufficient work front 200 meters or more. These restrictions greatly narrow the area of effective application grader – elevators. Their share in total production of earthworks does not exceed 1%.

3D-technology In The Casting Of Metals

States intend to reorient domestic export-oriented industries in the domestic market with a challenge of building an effective domestic demand for the products of industry. Construction and engineering as consumers of the metal – it’s now those two industries that determine the development of the country and are in dire need to introduce high-tech, metal-and energy-saving technologies. The most popular have exactly these projects in the field of innovative technologies. Domestic metal and engineering industry in terms of system integration into the global economy of our country as a full member of WTO, with the advent of inexpensive surplus metal receive an additional incentive of the transition from shallow processing and export of steel products to produce high technology products (machines, tools, appliances and tools). Actress has firm opinions on the matter.

This is a definite challenge national scientists and engineers, a decent answer to which will more fully realize the advantage that Ukraine is among the few countries with a closed cycle of metallurgical production of metals from own ore. In particular, in the domestic foundry engineering science has technologies related to knowledge-intensive high-technology, which can be attributed entirely modern varieties casting on gasified models (LGM, the English version of the Lost Foam Process) and that contrary to popular stereotype suggests that high technology – is not necessarily complicated processes inaccessible. In the engineering of Ukraine with the appearance of the years of independence in place large-scale production of the set medium-sized independent companies with their characteristic small series and diversified productions flexible technology foundry production combined with low capital costs of implementation and high precision workpieces produced a decisive factor. These parameters is consistent with FF technology, which supports global practice of continuous growth in production of castings in this manner, which has already reached 1.5 million tons / year, one in China works to one thousand of such sites with the active use of this technology in the automotive and engine building..

Syktyvkar Forest Institute

Every modern company to achieve high performance industrial activity aims to use new technology and modern scientific developments. When it comes to private business and private investment here every businessman believes the quality of priority roads that are technology that brings a profit. Almost to the organization of innovative construction of field roads are suitable in the Komi Republic. Despite seasonal road construction and the limited time of technological operations on the construction of zempolotna at subzero temperatures in the Komi Republic, to introduce such technology should, says director Usinsk Generating Company, Shevchenko, AN Far for examples of state roads do not have to go – just look at the roads that are built for himself the oil. Carrying capacity of vehicles and machinery used the extraction of raw materials, many times higher than the standards for public roads. From this condition they become dire, and expensive maintenance equipment.

Therefore, we concluded that the project design solutions and materials used must provide adequate bearing capacity and reliability meet road design. One of the priority areas and development of oil and gas industry in Komi an update of old and new road construction, for mining of natural resources, as well as construction and maintenance of roads – the links of one chain. Back in June 2009 in the Komi Republic with Syktyvkar Forest Institute, schvedskimi scientists and Russian companies involved in the development of new technologies in road construction, held scientific-practical conference devoted to the construction of roads of economic importance. The outcome of this event was the commissioning of the experimental section of the road, built on modern technologies. Technology used was developed specifically for the conditions of the Republic of Komi, where the missing stone materials to create pavement, wetlands, poor soils. In such areas are often lezhnevki. Enterprises of the Komi Republic and the regions have appreciated a simple in execution and not expensive in terms of material technology for road construction.

Visual Studio

The garbage collector runs periodically within the CLR, automatically restoring the unused memory for inaccessible objects. This model eliminates the low-level details of manipulating the memory of C + + and the involvement of reference counting COM.Bezopasnost types. When you compile an application. NET adds to the assembly information about the classes, their members, etc. This type of data and allows other applications to use them, without requiring additional support files, and compiler – to ascertain the correctness of a query directly into the runtime. This additional level of security is fully eliminates the risk of all types of low-level oshibok.Rasshiryaemye metadata.

Information about the classes and members is only one type of metadata. NET can be stored in a compiled assembly. Metadata describes the code and allow you to provide additional information the runtime and other services. For example, the metadata may indicate the debugger how to run the tracing code, or tell about Visual Studio how design-time should be displayed any special control. They can also be used to enhance more public a service at runtime, for example, to activate transaction or the pool . error handling.

Languages. NET supports structured exception handling that allows you to organize error handling logical and consistent manner, ie, create for different types of errors for the individual blocks and exception handlers placed at a depth of as much as several urovney.Mnogopotochnost. The CLR provides a pool of threads that can be used in different classes. For example, you can asynchronously call methods that read files, or to interact with Web-services without having to explicitly create new threads. Fig. 2 shows a high-level structure of the CLR and the. NET Framework. Fig. 2. CLR and the. NET Framework Fifth fact: ASP.NETyavlyaetsya object-oriented technology It not only provides full access to all objects in. NET Framework, but also allows you to use all the concepts of object-oriented programming (OOP).
