The company "Alley Software" participated in the interregional scientific-practical conference "The University Library: responding to challenges", held December 1-2 at the Urals State University. 110 participants conference (among them – representatives of 27 libraries of universities and IT-companies and publishing houses have come from 13 cities of Russia. The main question under discussion the speakers and the audience – the functioning of the university library in conditions of rapidly developing information society. Have been affected by the possibility of new services, increasing the role of libraries in the educational process, the issues of recruitment and knigoobespechennosti, increase the interest of students in reading, place the library in the World Wide Web and the introduction of social services to establish close contacts with users, the organization of educational work of the library. Considerable attention has been paid to the conference to provide access to electronic editions of teachers to students of universities. At the conference a round table "Electronic Library System: pro et contra, in which Representatives of five companies: Software Alley, Knigafond, Inc. "Direct-Media," "Biblioteh", and the educational and publishing center "Academy." Have been affected by all the important aspects of working with eletkronno-library systems from providing electronic access to publications to build the library information Dondo.

Specialist "Software Alley," Nikita Melnikov, spoke about various issues create internal systems at the university: standards and requirements of the GEF GER – including registration – to the DEC, the current situation in universities, the market data systems and the scheme of their creation. According to the speakers and listeners, the format of the roundtable, which involves an open discussion after the speeches, did talk very much alive and vibrant. "Because in a round stode were active simultaneously all the speakers, it was possible to clearly trace how the issue has been resolved each company and to objectively evaluate and compare the solutions proposed for the DEC. " – Said Nikita Melnikov, manager of "Alley of Software" – "were pleased plenty of questions, personal comments and opinions from the audience – Ural library region can rightly be called one of the most active. I would like to thank the organizers of the conference: the event was a bang, as listeners and presenters were pleased with the results obtained and a lot of new useful information. For those who have not had the opportunity to attend the conference, we posted a video recording of reports. "

Sandwich panels – a modern construction material, without which it is impossible to imagine both civilian and industrial construction. It's lightweight design, easy to install and incomparable to any material in their heat and sound insulation properties (100 millimitrovaya panel with mineral wool insulation on its thermal insulation properties of 7 times the brick wall of the same thickness). The main purpose of the sandwich panels – Protecting designs in the construction of prefabricated buildings. Sandwich panels are of the following types: wall, roof, ceiling (used in decoration) partitions, including fire; facing (used in the reconstruction and insulation of old buildings) panels for cold rooms. The application of sandwich panels: industrial buildings, warehouses, service centers, shopping malls, sports facilities, medical complexes, including "Clean rooms", the building-"fridges"; agricultural buildings, reconstruction of buildings and structures.

The design of multi-layer sandwich panels, as follows from name. The most common type – frame consisting of two shaped steel sheets, filled with insulation. The use of profiled steel sheet attached to the panel rigidity. As a rule, ends represent a kind of "lock" that makes it easy to mount, and in some designs to avoid the so-called "cold bridges". The most common insulation sandwich panel mineral wool, polystyrene, polyurethane foam. Mineral wool – a natural material made of silica rock melts the synthetic resin binder, and polystyrene foam – plastics. Heaters fairly waterproof, but the mineral wool as the absorbent material, yet is able to absorb moisture, which greatly reduces its thermal and sound insulation properties. To reduce this gap by manufacture of sandwich panels used vapor sealing materials.

Sandwich panels with polystyrene insulation from completely moisture resistant. The thickness of sandwich panels ranged from 50 to 300 mm, depending on the application and region-building. Weight sandwich panels as thick as 100 mm of polystyrene insulation with 1.5 easier panels with mineral wool insulation. This figure makes polystyrene foam insulation panels with a more attractive when construction, as reduced transportation costs and the load on the foundation of the building. The difference of heat-insulating properties of different insulation is low, it varies between 15% and EPS retains heat better. The level of fire resistance is higher in the mineral wool: under high temperatures, it can break down, but does not support combustion. Perhaps, therefore, a sandwich panel with insulation that are most common in Russia.

Parquet lacquers – have the best resistance to wear, or everyday language – to wear. They are not resistant to the effects of sun, rain, not willing to strong temperature variations. But in the case of a fall on the floor various household items coating compositions based on such an honor to stand the test. Produced types of parquet lacquers, which are composed of polyurethane resin coating to give elasticity. This addition allows withstand seasonal or age-related strain of the tree and at the same time helps to avoid cracking of the wood surface. Abbreviations used (for domestic varnishes): AC – alkyd, acrylic, AK – polyacrylic, AU – Alkyd-urethane, BT – Bituminous, VA – polyvinyl acetate, GF – glyptal (used to produce primers GF-021), MA – oil, MCH – Urea, NC – nitrocellulose, diluted with solvent 646, PE – polyester, PF – pentaphthalic, SD – Polyurethane, HV – perchlorovinyl, FL – epoxy, EF – epoksiefirnye. In addition, one of the characteristics of a gloss varnish to%.

Gloss varnish has glitter – 80-90%, semi-gloss – 40-50%, 10-15% Honed. Tips: – To cover with varnish floors, which are in use will be subject to heavy load, it is better to use polyurethane varnish. They are more resistant when compared with acrylic or alkyd. – To avoid loss of color and all sorts of troubles related to color the surface, which may occur over time, we recommend you first soak the work surface antiseptic, and other protective compounds before applying the lacquer itself. – The application of additional layers of coating gives better resistance to external influences. So it is better to apply two or three thin coats than one thick.

– The surface, and it is very important to be 100% dry, flat, buffed from grease recommended by the solvent. The surface should be dust and dirt. – For the best quality and smooth coating to use polishing. The first layer of varnish can be sanded grit abrasive sandpaper fine. This will improve the quality of adhesion to subsequent layers. – Remember that many lakes, including two-component, are toxic! Before applying please read the instructions and, if necessary – use personal protective equipment: rubber gloves, respirators and goggles. To varnish and paint in a closed unventilated room is dangerous!
