Almost all metal at OJSC «Byelorussian Steel Works» – management company of holding «Belarusian Metallurgical Company» includes today a mandatory physical-mechanical tests which allow to estimate the parameters of the raw materials, to know the reasons for loss of strength and determine operational characteristics. In the Central Factory Laboratory (CFL), laboratory of physical and mechanical tests (LPMT) for the preparation of samples of reinforcement equipment is used of knives in the cutting machine SIMA GEL-30 for cutting rebar from the mill 320 rolling shop № 1 with a diameter from 6 to 24 mm. In the drop-hummer shop annually discards off for scrap waste up to 50 knives. Hydraulic shears of drop-hummer shop used knives set of production of OJSC «Kobrin tool plant «SITOMO», made of steel grade 30ХСНВФА, according to the TU14-1-4461. The staff of the Central laboratory LFMI proposed to use waste knives drop-hummer shop for the manufacture of knives for the chopping of the machine SIMA GEL-30. On the basis of the conducted researches the technological scheme was developed for production of knives for the chopping of the machine SIMA GEL-30 cold cutting of reinforcing bar mill 320 the rolling shop № 1.

1UKRAINIAN MEDICAL STOMATOLOGICAL ACADEMY, POLTAVA, UKRAINE 2 ABSTRACT The aim of out research was to determine the effectiveness of the sealing property of adhesive systems V and VII generations by studying the depth of curing, water absorption and water solubility of their samples. Materials and methods: The study was performed according to ISO / TS 11405: 2015 at the Central Factory Laboratory of JSC “CTOMA”, Kharkiv, Ukraine, Certificate of Attestation No. 100-062 / 2015 dated 03/04/2015. For the study we used specially prepared laboratory samples which were made in the form of plates from adhesive system “DC Adhesive NF” (Dental Central) of V generation “Single bond Universal” (3M ESPE) of VII generation. А monitor and analyze the results obtained used micrometer MK-25, №4694, №03 / 5321 from 08/18/17; caliper SC-1, No. 267447, No. 03/5322 from 08/18/17; scales AP 210, №112144137, №87027 / 9 from 24.11.2017 Results: According to the results of the investigation the following results were obtained: 1) the average curing depth of V and VII generation of adhesive systems was 4.08mm and 3.51mm respectively at the rate of 2mm; 2) average water absorption: 45.97 μg/mm3 and 30.89 μg/mm3 for V and VII generations respectively; 3) the average water solubility was 6.94 μg / mm3 and 4.17 μg / mm3, respectively. Conclusions: According to the results of our laboratory studies, it can be concluded that adhesive systems of V and VII generations can be used for restoration of lesions of tooth hard tissued. Along with this, it can be recommended to use V generation adhesives in closed defects where direct polymerization should be performed and oral fluid access is minimal. Adhesive sysyems of VII generation can be recommended in such cases as: opened restorations, pregingival areas of teeth, cases where a permanent contact of restorations with oral fluid be found along with the cases of autonomic application of adhesive system.

The testing laboratory is obliged to plan and realize the actions guaranteeing quality of the carried-out tests. The main directions of this work are:• participation in programs of check of qualification (interlaboratory collating tests (ICT); • application of standard samples; • retests, encoded tests, check by other test method; • statistical control methods.But at the same time it is necessary to use and analyze all sources allowing to estimate quality of the carried-out tests. Such sources could be responses of consumers of production; tests, the procedures of certification of production which are carried out in independent laboratory when carrying out; the ICT organized by both the consumer, and testing laboratory.

The relevance of research in the factory laboratory of JSC «198 KZHI», which is part of the HC GVSU «Center», is dictated by the need to dispose of foam polystyrene waste that occurs in large quantities when producing the precast concrete. In the production of three-layer external wall panels, polystyrene heatinsulating plates of the PPS 17-R-A brand are used as an effective insulation material. The secondary use of PPS 17-R-A for its intended purpose, as a heater, is not possible. The volume of foam polystyrene produced varies from 25 to 45 m3 per month. Utilization (disposal) of foam polystyrene waste is an expensive undertaking. Its use as a filler in the production of expanded polystyrene blocks was tested in the factory’s laboratory to produce foam polystyrene concrete with specified physical and mechanical characteristics. The results of testing of expanded polystyrene concrete of classes B2.5 and B 7.5 are presented. It is shown that under the conditions of the reinforced concrete factory technology, the production of polystyrene concrete blocks is possible with the achievement of the design strength. The information presented in the article is aimed at motivating specialists who produce recast concrete to the possibility of using foam polystyrene waste for low-rise construction. Keywords: foam polystyrene, ecology, energy efficiency, foam polystyrene concrete, foam polystyrene heat insulation plates, precast concrete.

As If

Present biologic models envision organisms behave like the character ‘Topsy’ in Gone with the Wind; they “just grew.” Modeled of Lego©-like components, the individual structures are linked together as if they are automobile parts that are manufactured at different plants and assembled at some central factory. For the most part, hexahedral finite element meshes are used to model structures. When tetrahedral modeling is used, no account is made of the different mechanical properties that are inherent in triangulated structures, (trusses), that make the structures behave very differently than hexahedral-based models.

Problems involving path planning, exploration, and related activities abound in the world of computing. This paper develops a novel model for realizing ant-inspired algorithms that coordinate robots within fixed, geographically constrained environments ("factory/laboratory/warehouse floors") and studies the model via sample tasks that illustrate various aspects of path planning and exploration. The model, dubbed a Cellular ANTomaton (C-ANTomaton, for short), inverts the relationship between ant-robots and the environments that they navigate: "Intelligence" now resides in the "floor" rather than in the ant-robots. The C-ANTomaton model is illustrated via three proof-of-concept problems: (1) Parking requires ant-robots to congregate in their nearest corners of the "floor," in a maximally compact formation. (2) Food-seeking (both with and without impenetrable obstacles) requires each ant-robot to find its own "food" item, until either "foodless" ant-robots or unclaimed "food" items run out. (3) Maze-threading requires a single ant-robot to find the unique exit to a maze. "Unintelligent" C-ANTomaton-based robots accomplish all of these goals provably more efficiently than traditional "intelligent" ant-robots can; indeed, "intelligent" ant-robots cannot always park at all! All of the presented algorithms are scalable, in that they provably work for any number of ant-robots, within any finite-size "floor." In other words, the computers that collectively supply the system with "intelligence" never exploit any information about either the number of ant-robots or the size of the "floor."

External quality control of the chemical-analytical departments of the central factory laboratories was carried out: PJSC Krasnoarmeysky Dinas Factory, PJSC Chasovoyarsk Refractory Plant, PJSC Velikoanadol Refinery Plant. During the chemical analysis of samples of refractories of the listed enterprises, the analysis methods, equipment and materials described in DSTU 3305(3, 4, 5)—96 (GOST 2642.(3, 4, 5)—97) — gravimetric (SiO2), complexometric (Al2O3), photometric (Fe2O3). As a result of the work carried out, conclusions were drawn up in which the quality of the work of the chemical analytical units of the central factory laboratories of the PJSC “Krasnoarmeysky Dinas Factory”, PJSC “Chasovoyarsk Refractory Plant”, and PJSC “VELIKOANADOL REFRACTORY PLANT” was considered satisfactory.
