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.

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."

Taking advantage of three-dimensional software Solidworks to model for solar modules and also using finite element analysis software Ansysworkbench to conduct the stress analysis and strength check of modules, to analyze the deformation of modules under certain loading conditions, to conduct load tests and defect detection (EL experiments) and to optimize encapsulation with aluminum frame combined with the factory laboratory. The results show that: the modules have no crack and other defects and their power attenuation does not exceed the specified value after the 2.0mm thickness aluminum frame was reduced to 1.7mm.

Managing liquid waste from the laboratories of Integrated Agricultural Unit (IAU) of Zuénoula (Côte d´Ivoire) is a major concern for the decision-makers of the company, who are working to solve this problem in their sustainable development policy. This work aims at quantifying liquid waste from the agronomic laboratories and factory of IAU of Zuénoula and to assess their level of pollution. The quantities of waste produced daily are estimated at 28.5 L, 52.6 L and 2600 L respectively for waste from the agronomy laboratory, the factory laboratory and from the rinsing water from latter's glassware. The following parameters were analyzed, temperature, pH, conductivity, turbidity, total suspended solids, COD, BOD5, total nitrogen, total phosphorus, zinc, copper, lead and mercury. The results of these analyzes generally showed that waste produced did not comply with national standards. In particular, the level of lead was very high in these liquid wastes and reached 160 times the standard value. These results require a waste treatment system, which would reduce all the parameters, in particular those of the most noxious metals (lead and mercury).Keywords: Heavy metals, Pollution, Industrial unit, Ivorian standards, Wastewater.

The article provides information on the results of assessing the quality of concrete internal wall panels. The requirements of various regulatory documents for the rules for accepting a batch of concrete are considered. The procedure of statistical sampling control on a quantitative basis is described. According to the statistical data of the factory laboratory of Open Joint Stock Company “ZhBK-1” (Penza) on the quality of grade 300 concrete in the manufacture of internal wall panels, the influence of the type of cement on the variability of concrete strength indicators is considered. The influence of the type of cement on the decision to accept a batch of concrete is established. Due to the higher value of the standard deviation of the quality indicators of Haldenberg cement in comparison with Sengileevsky cement, the acceptance of a batch of concrete depends on the level of product defectiveness. It is revealed that, depending on the number of samples during testing, the decision on batch acceptance, made in accordance with GOST 10180-2012 and GOST R ISO 12491-2011, may be different. It is proposed to amend GOST 10180-2012 in paragraph 4 regarding the number of samples for testing, taking into account the requirements of GOST R ISO 12491. This will contribute to a more objective decision on the acceptance of the batch. The effect of the type of cement on the reproducibility of the production process is shown.

The article provides a comparative assessment of the requirements for the quality of ketchup in Russia and the United States. Differences in requirements relate to many indicators, including consistency. It is shown that the viscosity of ketchups is achieved in two ways: by the introduction of a certain amount of thickeners, or the development of recipes based on a special tomato paste made using the Hot Break technology. The task of the study was to determine the viscous characteristics of ketchups of different names, to select equipment for determining the viscosity of products in the factory laboratory conditions and to formulate prescriptions with specified parameters.
