The architectural design of private homes focusing on the design of the heating system. Properly design and install heating system will help professionals who specialize in this area. They help you select the project, it is suitable for your home. Since the design of heating systems can be divided into several stages. First, determine the type of coolant circulation. Circulation is a natural and enforced.
In the natural circulation pump is not used, which means that this type of circulation has a certain independence from the electricity. But at the same time by using the heating system with natural circulation has drawbacks: large diameter pipelines, adherence slope, there are difficulties in adjusting the heat, the inability to control some elements of the system. If there are no forced circulation problems, but it strongly depends on the source of energy. The landlord must, at the initial stage of design to choose the type of circulation, because this will depend on the range of devices, appliances and heating units. Second, during the design of the premises is necessary to provide openings in the walls, the floor that will be needed for the distribution of heating collectors, sewerage and water supply: country house heating, heating in the cottage.
Technological holes will hide all the elements of engineering systems at the same time provide access to them for maintenance and repair work without disrupting the design space. Third, choose a location for the boiler house and build a channel for the chimney. In addition to the chimney brickwork should pave the steel pipe to protect the brick from the condensate, which can occur when large temperature differences during the winter. Fourth, determine the number of sections of the radiator. To do this, calculate the number of square meters, which can warm up one section. The formula is simple: heat one section must be divided by 100. For example, calculate how many radiator sections you need for rooms of 16 m2. Determine how many meters obogreet one section of the radiator. To do this, heat equal to 199 divided by 100 Tues, the result is about 2 m?. Therefore for rooms of 16 m2 will take eight sections. If the room is a balcony or a room in the house corner, you will need to increase the number of partitions in two or three.
Recently, in the modern art of Russia is very active declared itself an image Dry brush technique. It would not have ignored its existence official cultural institutions and society to do this is becoming harder and harder. There is evidence that it originated among the decorators in the Soviet era and was used to create visual-propaganda sites, including portraits of political leaders of the Soviet Union and other celebrities. As a basis for work performed in this technique, most often served as a fine-grained white negruntovannaya tissue, such as linen stretched over a rigid design – sub-frame. Paint usually oil was applied on the basis of a thin layer of rubbing. White is not used, the white color is provided by the whiteness of the inspected unpainted bases. The advantages of dry brush are a minimum of consumables materials, the relative speed of execution (a thin layer of paint dries faster) and, if using oil paint, the paint layer sufficient strength, resistance to water.
All these qualities are evident is a big plus for campaign objects created for specific events, holidays and celebrations, and exhibited a limited amount of time outdoors. But as time passed, there were various political and economic changes and the relevance of such use dry brush gradually fell away. But what is unknown to the wind this technique skidded on Wednesday appeared at that time, street artists, portrait painters, and it gained enormous popularity there. For the first time I had the opportunity to observe the portrait art of dry brush in that way, the 1986 seventh, when he was passing through Moscow and went on a walk at that time became a pedestrian Arbat Street. Eastern-looking group of guys, sitting around with a sketchbook and chairs, smartly worked on the creation of images of willing walkers. As I later found out later it was kind of like the Koreans from the Stroganov.
Thus, when tamping the way two people can shpalopodboykami to work with 2.4 or 6 jacks. Rams set to shpalnye boxes in pairs under each rail through 8 … 10 boxes. In the course of the rear pair of jacks consistently rearranged in 8 … 10 shpalnyh boxes next to the front of work (Detail the technology of production of various types of track works, using jacks and other MPI, including hydraulic, described in the applicable legislation, such as instructions for the current maintenance of railway track. – Moscow: Transport, 2000 1 Regulation and implementation of the basic technology works with the current contents of the path.
– Moscow: Transport, 1998. 2). Rihtovschiki with manual transmission and the executive motor rihtovschikov placed near the rail (the side opposite to the direction of the desired slight shift) so that the double-hinged arm and shovel were placed under his soles. If the surface of the ballast is contained in a good state, then the installation is not required to align rihtovschika ballast and remove it from the rail in shpalnom box. The executive bodies of both manual and motorized rihtovschikov set at an optimal angle to the horizon (defined almost as a function of the track panel weight, degree of compaction of ballast, the quantities required Sdvizhkov way, the number used in set viewed by rihtovschikov, etc.), so that does not support slip in ballast and not unduly raised her path (25 mm).
Miles for a camel-the next edition of the legendary rally with participation from the Ruhr area which Allgau-Orient rally is a low-budget rally about 6000 km for people who love the calculable adventure, and for a good cause the one or the other strain to take. The Organizer even call the rally one of the last automobile adventures of this world”, and it has evolved from the sneered spinner event to one of the biggest rallies of the world. Among other things through the growing coverage of print and TV media, the international field of participants initially 40 teams currently 100 teams has grown with usually six team members and three cars per team. In 2011, six young men from the Ruhr area in the age between 28 and 35 years in your elderly honey on the way will make so: stroker ACE racing team! The team takes 6000 km in attack as of April 30. Team leader Christian Becker and the fellow Christoph Kleinebrahm, Arne Hauner, Jan Christopher Klotz, Andreas Steffen and Daniel Alexander SEIM must have arrived at the latest on May 12 with hopefully all vehicles in Amman.
As in previous years, the rally cars in Amman will go program in the possession of the world food over 2011 and offering maximum auctioned. In the last five years a six-digit amount could be provided through the proceeds of the vehicle, additional donations of participating teams and the sponsors the WFP. The money flows on a blocked account of WFP and will be paid for the intended purpose for the projects, which are supported by the organizers of the rally. If you want to support the team and especially the good cause of the rally and contribute to a win over at least some suffering in this world, the team members about any kind of support it offers. Finally, the rally car in Jordan can only be auctioned, when they arrive there. Since the rally participants fly back to Germany, few equipment can return to be made.
All of the cars abandoned items are considered to be donated and are also used for humanitarian purposes in the country. Send your name for a small donation across Europe to the Orient for more information about this project on. For questions we are gladly available.

In the design of any product want to make it practical, technologically advanced and durable. This is achieved by correct selection and the material, and an increase in precision manufacturing. However, loaded with details, or working in argessivnyh media exposed their work with the action of the destructive forces of friction and chemical corrosion, and therefore the question arises and surface protection products. Among all the modern methods of chemical heat processing of steel products, such as cementing, nitrocarburizing, carbonitriding and gas nitriding in ovens most efficient and technologically advanced method is the ion-plasma nitriding. The essence of this the method is controlled modification of the crystal lattice of the workpiece in the surface layer by ion implantation.
Ion implantation – is the introduction of a solid surface practically any ion, pre-overclocked to electromagnetic pole.Eti ions are introduced into the material to a depth of 0.01 to several tens of microns, creating a surface layer of a special strkuturnoe state. The thickness of modified layer depends on the ion energy, mass and mass of the target atoms. The ion energy can vary widely (depending on the material properties combined ion – target) 1 (keV) to several MeV (MeV). Besides the introduction of the ion in the target surface occurs without complying with the laws of classical thermodynamics, which determines the equilibrium processes such as diffusion. Office of the penetration depth ions in the surface layer by changing the ion beam energy and the number of ions entering the target per unit time (Fig. 1) Li-ion plasma nitriding (IPA) – a kind of physical-chemical treatment metal parts, tools and other equipment, allowing the product to saturate the surface layer of nitrogen in the nitrogen-hydrogen plasma at 500 0C.
The essence of the method of the IPA is that discharged to 200-300 Pa nitrogenous gaseous medium between the cathode, which are the workpieces, and the anode, which serves as the walls of the vacuum chamber is excited by the anomalous glow razryad.Imenno it generates reactive species ionization of molecules of the gas environment (ions and radicals). This provides a form on the surface of the workpiece of the nitrided layer consisting of a foreign – nitride zone and settling down beneath the diffusion zone. By changing the composition of the gas in the chamber, its pressure, working temperature and exposure time product in a cell, you can get layers of a given structure and phase composition, providing a strictly regulated properties of steels and alloys. Improving the properties of hardened surface provides the required combination of nitride and the diffusion layers, which seem to "grow" in the surface layer of core material. At the same characteristics and properties surface layer is completely determined by its chemical composition: the nitride layer is either the Y-phase (Fe4N), or E-phase (Fe2-3N). Layer with E-phase is a corrosion-resistant, and a layer of Y-phase of a durable and relatively malleable. In this case, depending on the purpose of processing, as a result of ion-plasma nitriding can get: a diffusion layer with a developed area of nitride, which provides protection against corrosion and friction running-in surfaces – for parts operating under friction, the diffusion layer without the nitride zone – for cutting and stamping tools and parts operating under conditions of alternating loads of wear at high pressures. Ion-nitriding improves plazmenennoe following product characteristics: wear resistance, fatigue endurance antizadirnye properties, heat resistance, corrosion resistance.
Copper or brass pipe with bending in the cold state, the molten resin is filled. Bending process is similar to that described above. Rosin after bending is smelted from the pipe ends, as at mid-heating pipes, filled with resin, the cleavage of her. Copper and brass tubes for bending in the cold able to anneal at a temperature of 600-700 C and cooled in air. Fillers for bending copper pipes in a cold resin and heated in – sand.
Fillers for the brass tubes are the same as that of a flexible copper tubes. Duralumin tube to a flexible annealed at 350 – 400 C and cooled in water. After this treatment, the tubes are bent well over two hours. With mass production of parts from tubes used hand-held Pipe-bending devices and beam bending, and bending large diameter pipes – special pipe bending machines and press. Recently, extensive use of flexible tube with a stretched piece and the heating currents high frequency. When bending the tubing is stretched preform is subjected to tensile stresses exceeding the yield strength of metal and then bend.
This process is carried out on the bending and rastyazhnyh machines with rotary table for Pipe bending planes, cars, marine and river vessels and other parts manufactured by this method have high strength. When bending pipes with heating by high frequency heating, bending and cooling occur sequentially and continuously in a special high-frequency setting, which consists of mechanical and electrical parts. The mechanical part of a machine for bending pipes, and electrical and electrical equipment consists of inducer. Installation allows bending pipes from 95 to 300 mm. The above method has several advantages: it provides a lower roundness Bends in pipes, high performance (4-5 times higher than the other way), the mechanization process. Are properly curved pipe, no dents, bulge and crease. The reasons for marriage in bending and straightening when bending metal marriage is most often seen in oblique bending and mechanical injuries treated surface as a result of improper marking or fixing the details in the grip up or down a road marking lines, as well as improper attacks. When you edit the main reasons for marriage are the dents, the marks of the hammer Hammer, Nick on the treated surface of the hammer. These causes are the result of a hammer, to whom there is a lively and Nick vyscherbiny, misuse attacks.
2.5 To 3.0 upgrade process must be automatic and simple, similar to previous updates.Users can choose depending on the site by site, if you have automatic updates check for version updates LTS (by default) or updates of the version of STS.Depending on that choice, different update notifications will display when accessing back of site administration. Version 3.0 system requirements requires the version of PHP 5.3 and MySQL version 5.1 (with MySQL 5.5 recommended web designer).We are going to continue supporting Microsoft SQL Server and he is expected to be adding support for Postgresql.ademas, he has been proposed for release for the old driver mysql support in PHP and they require the use of the new mysqli driver.Finally, intends to require MySQL InnoDB engine inside.INNODB is required for some of the new platform tables.None of these changes should cause problems for hosts that offer up to date versions of software.In addition, it will be at least September 2013, before existing sites you will need to upgrade to version 3. Important due dates the Joomla CMS is a time-based release cycle, we have be strict in terms of cut-off dates.These are the proposed dates: July 1:. The package’s alpha 3.0 version this is mainly to test third party extensions after the removal of files from the platform to the folder of the CMS. characteristics need not be ready by then, but that may be included if they are ready.
1 August:. Version of the package 3.0 beta this should contain all the features that will be in version 3.0.To make this happen, all the features of 3.0 must be prepared to merge prior to this date. September 1: version 3.0 RC1.This must be very close to a final version. 15 September: version 3.0.0. Diseno web madrid – web hosting
