Представлены результаты исследований физико-механических свойств, химического состава и показателей безопасности составных частей (мякоть, кожура, семена) дыни сорта «Торпеда». В результате сопоставительного анализа химического состава мякоти, кожуры и семян дыни показано их существенное различие. Так, содержание жира в мякоти составляет 0,26±0,003 г, в кожуре - 1,24±0,01 г, в семенах - 26,21±0,31, содержание белка составляет 7,56±0,11; 9,92±0,14 и 21,52±0,32 г соответственно. Изучение содержания редуцирующих веществ и сырой клетчатки показало их высокое содержание в кожуре по сравнению с мякотью и семенами. Установлено, что высокое содержание калия (934,88±14,02 г) и натрия (270,54±3,78 г) сосредоточены в мякоти, высокое содержание железа (15,12±0,23) - в кожуре, а высокое содержание фосфора (854,72±0,82 г) - в семенах. По результатам исследований доказано, что показатели безопасности дыни сорта «Торпеда» полностью соответствуют требованиям ТР ТС 021/2011. The results of studies of the physical and mechanical properties, chemical composition and safety indicators of the constituent parts (pulp, peel, seeds) of «Torpedo» melon are presented. As a result of a comparative analysis of the chemical composition of the pulp, peel and seeds of the melon, their significant difference was shown. Thus, the fat content in the pulp is 0.26±0.003 g, in the peel - 1.24±0.01 g, in the seeds - 26.21±0.31, the protein content is, respectively, 7.56±0.11; 9.92±0.14 and 21.52±0.32 g. The study of the content of reducing substances and crude fiber showed their high content in the peel, in comparison with the pulp and seeds. It was found that a high content of potassium (934.88±14.02 g) and sodium (270.54±3.78 g) are concentrated in the pulp, a high content of iron (15.12±0.23) - in the peel, and a high phosphorus content (854.72±0.82 g) - in seeds. According to the research results, it has been proven that the safety indicators of the Torpedo melon fully comply with the requirements of TR CU 021/2011.

На основе выполненных в работе исследований проведен сравнительный анализ изменения свойств активированных и не активированных смесей и мелкозернистых бетонов на их основе в зависимости от разной удельной поверхности тонкодиспесрных наполнителей: трепела или песка от содержания микронаполнителей: высокоактивного метакаолина, волластонита и водоредуцирующих добавок-суперпластификаторов С-3 или Melflux. Показано, что при переходе на другой вид наполнителя, даже такого же химического состава, оптимальные дозировки всех компонентов и их соотношение необходимо корректировать. При переходе на другой вид приготовления смесей соотношение компонентов также изменяется. Теоретически обоснована и экспериментально подтверждена эффективность совместного использования тонкодисперсных наполнителей заданной дисперсности, суперпластификатора С-3 или Melflux, высокоактивного метакаолина совместно с волластонитом в составе смесей для мелкозернистых бетонов в качестве полифункциональных модификаторов. Проведенные исследования показывают широкие возможности модификации составов органоминеральными экологически безвредными добавками и свидетельствуют о рациональности разработок комплексных полифункциональных модификаторов отдельно для активированных и не активированных мелкозернистых бетонов. Для активированных смесей рационально также нормировать более широкий спектр технологических свойств. Практические результаты, полученные авторами, обеспечивают как повышенные по сравнению с нормированными, так и высокие дополнительные показатели качества. Высокая степень влияния количественного состава мелкозернистых бетонов полифункционального назначения на их свойства предопределяет актуальность разработок универсальных программных комплексов. Разработана информационная модель системы поддержки принятия решений в процессе анализа свойств мелкозернистых бетонов полифункционального назначения.Based on the research performed, a comparative analysis of the changes in the properties of activated and non-activated fine-grained mixtures and solutions depending on the different specific surface fine fillers: finely ground trepel or sand, as well as on the content of inorganic PFM: highly active meta-kaolin, wollastonite and super-plasticizing additive superplasticizer C-3 or Melflux. The carried out researches show wide possibilities of modification of compositions by organomineral ecologically harmless additives and testify to rationality of development of complex additives separately for the activated and not activated fine-grained solutions. It is shown that when switching to another type of filler, even the same chemical composition, the dosages of all components and their ratio should be adjusted optimally. When switching to another type of mixture preparation, the ratio of components. Practical results obtained by the author provide the required and additional quality indicators, increase the physical and mechanical properties of fine-grained solutions, increase productivity. Theoretically substantiated and experimentally confirmed the effectiveness of the joint use of fine fillers, superplasticizer C-3 or Melflux, the high activity of metakaolin and wollastonite as a part of the binder in the fine-grained mixture and concrete. The data model of the decision support system for analyzing the properties of fine-grained multifunctional concrete has been developed.

The present experiment was aimed to study the effect of bee pollen on the meat chemical composition of broiler’s Ross 308 breast and thigh muscles. In the experimental groups were added bee pollen in an amount (group E1 – 2 500 mg.kg−1, group E2 – 3 500 mg.kg−1 and E3 – 4 500 mg.kg−1) to the feed mixtures for 42 days. At the end of the study the water content was higher in experimental groups than the control group and on breasts there were a significant difference (P ≤ 0.05) between control groups and experimental groups (E1, E2 and E3) also there was a significant difference (P ≤ 0.05) between the experimental E3 and experimental E1, E2 groups. In protein content, the control group was higher than experimental groups and there no significant differences (P ≥ 0.05) among the groups. In fat content, the control group (2.04%, 13.2%) was higher than experimental groups E1 group (1.59%, except thigh 14.11%), E2 group (1.70%, 13.00%) and E3 group (1.51%, 10.96%) and on breast there were significant differences (P ≤ 0.05) between control group and experimental groups E1, E3 and on thigh there were significant differences (P ≤ 0.05) between experimental E3 and experimental E1, E2 groups. In energy value (kJ.100 g−1) of the breast and thigh muscles in control was higher than experimental groups and on the breasts there were a significant differences (P ≤ 0.05) between control group and experimental groups (E1, E3) and on the thigh there were significant differences (P ≤ 0.05) between experimental E1 and experimental E3 groups. From the study we concluded that the bee pollen has a positive effect of the breast’s meat chemical composition of broiler, which led to increase the water contact and reduce the fat content and energy value, but he had a normal effect on thigh, also bee pollen has normal effect on the protein content of the breast and thigh muscles.

The study was to conduct to evaluate the chemical composition and nutritive values of feedstuffs (forages and concentrate mixtures) used for dairy goats nutrition in Vojvodina. Samples were collected from six farms, including one organic farm. The results showed that the relative feed values of analyzed forages were in the range of good, medium to lower quality. Average protein content from lowest to highest for investigated forages was: corn silage (Zea Mays) (65.37-82.57g kg??DM), alfalfa haylage (Medicago sativa L.) (159.99-184.17g kg??DM), pasture (185.30g kg?? DM), and alfalfa hay (Medicago sativa L.) (167.48-203.60g kg??DM). The non-fibre carbohydrates and protein content most varied in organic hay samples (cv: 29.25% and 19.09%, respectively). Generally, feedstuffs used in organic nutrition, including organic concentrate, were of lower nutritional quality and moreover contained higher amounts of crude fibre and lignin. Especially, a high source of variation was observed in investigated concentrate mixtures for the crude protein content (p<0.0001), ranged from 135.32 to 209.87g kg??DM. Corn silages also varied substantially in their chemical composition and significant difference (p<0.05) was observed in regard to acid detergent fibre (ADF) and lignin content (ranged: ADF: 242.20-319.24g kg??DM; ADL: 27.98-52.54g kg??DM, respectively). Furthermore, pasture contained the most soluble materials during May and June and their content was related inversely to crude fibre amount. This survey highlights that investigated farms still pay insufficient attention to the quality of the feedstuff. For the development of intensive goat farming, greater emphasis should be placed on using higher quality feedstuffs, as well, standards for feed quality must be considered and established.

Products Analysis

in recent years, great attention has been paid to the quality of eaten meat and its products. There have been launched a lot of promotional campaigns aimed at providing opportunities for the consumption of traditional products. Based on the experiment, a significantly higher protein content was found in sausages produced by large producers (24.73 &plusmn; 1.98%). The fat content was significantly higher in traditional ham (16.25 &plusmn; 14.47%), compared with local ham (4.38&nbsp;&plusmn; 2.26%) and the mass (9.29 &plusmn; 5.25%). The samples of traditional and local ham had a significantly higher salt content (3.31 &plusmn; 0.72 and 2.90 &plusmn; 0.54%, respectively). No dye compounds were detected in any of the tested samples. There were no statistically significant differences in hydroxyproline and l‑glutamic acid content between traditional and conventional samples of meat products. Analysis of nitrate (V and III) showed a statistically significant difference in the average contents of these compounds. Significantly higher levels of nitrates were revealed only in traditional ham samples (12.60 &plusmn; 8.08 mg NaNO(V)/kg and 17.53 &plusmn; 27.91 mg NaNO(III)/kg of the product, respectively), wherein there was a large variation in the content of these compounds in the samples.

Introduction. For the maintenance of the aseptic chain created during the treatment the coronal sealing becomes paramount. Aim. Evaluating the antibacterial effect and the physical-mechanical properties of a temporary restorative material containing different antibacterial agents. Material and Methods. Two antibacterial agents (triclosan and chloramine T) were manually added to a temporary restorative material used as base (Coltosol). The antibacterial action of the material was analyzed using the agar diffusion method, in pure cultures of Escherichia coli (ATCC BAA-2336) and Staphylococcus aureus (ATCC 11632) and mixed culture of saliva collection. The microleakage rate was analyzed using bovine teeth, previously restored with the materials, and submitted to thermocycling, in a solution of 0.5% methylene blue, for a period of 24 hours. The physical and mechanical properties of the materials analyzed were setting time, water sorption, solubility, and compression strength. Results. No marginal leakage was observed for all groups. There was no statistical significant difference in antimicrobial activity, setting time, water sorption, solubility, and compression strength among the materials. Conclusion. The addition of antibacterial agents on a temporary restorative material did not optimize the antibacterial ability of the material and also did not change its physical-mechanical properties.

The physical and mechanical properties of lightweight constructional heat-insulating concrete (sawdust gypsum concrete) with high-strength gypsum binder, modified by food cotton microcrystalline cellulose and organic fillers of plant origin from the waste wood of coniferous and deciduous species in the form of cavitationly processed pine and birch sawdust have been studied. The dependence of the cavitation extraction time of water-soluble reducing substances (sugars) from sawdust on the strength of sawdust gypsum concrete is established. The changes in microstructure of the gypsum matrix, the mean density, bending tension strength and compression strength, the thermal conductivity coefficient of sawdust gypsum concrete on the basis of the cavitationly processed sawdust with the introduction of microcrystalline cellulose are analyzed. It is proven that microcrystalline cellulose compacts the space between the crystalline hydrates of calcium sulfate dihydrate in the gypsum matrix microstructure and improves the physical and mechanical properties of sawdust gypsum concrete.

The objective of this paper is to study Fe65Nb-Cu metal matrices, thus varying the content of the pre-alloyed Fe65Nb powder from 10% to 100%. Therefore, powders of Fe65Nb and Cu were used, innovating in the chemical composition of the commonly used matrices. The objective is to evaluate the substitution of Co (toxic element, commonly used) by Nb (98.2% of reserves are Brazilian). For the sintering of the samples it was used hot pressing technique. The parameters were set at: 850°C / 35MPa / 3min. The sintered bodies underwent SEM/EDS analysis and density and porosity measurements were performed. From the results it is possible to say that the compositions of (10% and 30% Fe65Nb) presented the best physical and mechanical properties. The relative density decreases for the compositions with 40%, 50% and 60% Fe65Nb is justified by the presence of fragile particles in metal matrices, since they require more energy in order to efficiently transport matter (diffusion) in a solid state.

Binder material is the most expensive raw component of concrete; thus, scientists are looking for cheaper substitute materials. This paper shows that when manufacturing, a part of the binder material of expanded-clay lightweight concrete can be replaced with active filler. The conducted studies show that technogenic – catalyst waste could act as similar filler. The study also includes the dependence of the physical and mechanical properties of expanded-clay lightweight concrete on the concrete mixture and the chemical composition of the samples obtained. Different formation and composition mixtures of expanded-clay lightweight concrete were chosen to determine the properties of physical-mechanical properties such as density, water absorption and compressive strength.
