The quality of modern food products may be improved by adding bee pollen (PB) to the composition. The important stage of the process of improvement of an existent product or creation of new one is the optimization of the technology of bee pollen preparation, especially, comminution. The aim of the researches was to investigate the process of comminution and to optimize technological parameters for receiving high quality powder, used as a component of sour-milk beverages and other products. The study elucidates the influence of a series of factors on the size of particles and quality of bee pollen powder by technological and phytochemical properties. Using the visual method with modern optimal devices, it was established, that pollen can be comminuted to the particles size 120–8 mcm. The dispersity degree of received powder caused changes of the phytochemical activity and technological parameters of a product. The method of colorimetry determined that the content of flavonoids in pollen increases by 53 % at communiting to particle sizes 15±5 mcm and decreases at the higher dispersity. The screen method determined the homogeneity of the material, processed by three types of comminutors and substantiated the use of a mill-pestle in the technology of bee pollen comminution as the most effective comminutor. Using the plan of the complete factor experiment of the third kind, there were studied the surfaces of a response of the dependence of pollen powder homogeneity on the comminutor work intensity, mass and term of the material processing. Technological parameters of pollen comminution by a mill-pestle were optimized: working body speed 70–80 turn/min (min−1), processing duration – 6 min, batch mass – 150 g.

The research objective is to improve the quality of soil loosening using combined working bodies for surface moisture-retaining soil cultivation. The efficiency of accumulation and conservation of precipitation in the autumn-winter period depends on the method of post-harvest soil cultivation. One of them is the autumn surface water-retaining treatment, which makes it possible to increase the efficiency of the processes of accumulation and conservation of moisture due to the deeper loosening of the cultivated soil layer. During loosening and mulching, the top layer of the soil contributes to the accumulation and preservation of moisture not only in the upper but also in deeper soil horizons. However, the used tillage tools do not fully solve the problem of the high-quality performance of surface moisture-retaining soil cultivation. The article presents the results of studies of the degree of influence of geometric and technological parameters of the additional active cultivator on the quality of surface tillage. Based on the results of the research carried out, the technological process of performing the surface tillage operation has been improved and combined working bodies have been developed for its implementation.

The leading theme of this article is the enigmatic “hour” as revealed in the account at Cana (2:1-11). Jesus’ words to his mother, οὔπω ἥκει ἡ ὥρα μου (2:4), are considered obscure and difficult to interpret, causing an intriguing and unresolved controversy within Johannine scholarship. Most exegetes agree that this phrase is to be taken as a denial. According to them, Jesus announces that his hour has not yet come, because this “hour” is bound to the hour when “the Son of Man is glorified”, alluding to his being lifted up on the Cross and raised up “on the third day”. However, there is another solution suggested by a significant number of scholars. They propose reading Jesus’ words οὔπω ἥκει ἡ ὥρα μου as a question, which better guarantees the overall coherence of the story in light of the wider OT context. This interpretation focuses specifically on the temporal indication of “the third day”, the biblical image of the wedding, and the abundance and high quality of the wine, a beginning of signs and of the revelation of Jesus’ glory which serve to stimulate the faith of his disciples. In this view, this multiplicity of themes indicates that the meaning of the “hour” lies in the motif of fulfillment. Jesus is the Messiah who brings to perfection all that has been foretold in Scripture. His “hour” begins “now” and continues throughout his public life until it reaches its ultimate fulfillment in the glory of his Cross and Resurrection. The present article is focused, therefore, on investigating the interrelations among the main biblical themes brought to the fore in the Cana narrative, and their meanings in relation to the “hour” of Jesus.

In this paper, we focus on the electroplating technology used for RF micro inductor coil. The technological parameters in DC electroplating are determined by SEM, linear sweep voltammetry and so on. It turns out that a high quality of plating layer is obtained when the PH value of electrochemical solution is 9, temperature is 45°C,current density is 1 A/dm2, additive is added and stirred slowly. Then the research on pulse electroplating is conducted on the basis of DC electroplating, and the result indicates that the pulse plating layer is of better quality compared with DC plating layer. Afterwards, surface structure and resistance of the copper layer are analyzed, demonstrating the obtained coating layer is good enough to be the main structure of micro inductor coil. In the end, this electroplating technology is applied to micro inductor coil. The simulation, fabrication, package and test of micro inductor coil are introduced briefly.

Fluoride compounds have the most harmful effects on the environment. The main source of fluoride in the soil is phosphorus-containing fertilizers. Purification of wet-process phosphoric acid (WPPA) from fluorine will significantly reduce its content in phosphorous-containing fertilizers and improve the quality of the resulting products. The aim of the study is to reduce the content of fluorine and sulfates in the wet-process phosphoric acid by introducing calcium carbonate, dolomite or phosphorite into the finished extraction pulp before filtration and obtaining high-quality calcium and magnesium-containing phosphate fertilizers based on it. Phosphates were determined by differential photometric, fluorine – ionometric, calcium, magnesium, aluminum, and iron-complexometric, and sulfates-by weight methods. For the first time, scientifically-based data were obtained on the simultaneous reduction of the content of fluorine and sulfates in WPPA from phosphorites of Central Kyzylkum and the production of calcium-magnesium phosphate fertilizers based on it. Optimal technological parameters of the process of simultaneous defluorination and desulfatation of  WPPA from Central Kyzylkum phosphorites with calcium carbonate, dolomite and washed burnt phosphoconcentrate (WСPC) were found by introducing them into the second section of the extractor, into the finished extraction pulp in the amount of 100% for sulfate binding and 100-150% for fluorine binding, as well as obtaining high-quality products based on purified WPPA. The degree of transition of fluorine to the gas phase and phosphogypsum at a rate of 100-150% of calcium oxide for fluorine binding is 86.2-89.4% and its content in the wet-process phosphoric acid decreases from 1.18% to 0.22-0.29%. At the same time, the SO3 content in the acid decreases from 1.21% to 0.24-0.26%. The filtration rate of the sulfate-phosphate pulp varies slightly and is 807.6-812.6 kg/m2·h by dry residue.

Abstract: The present study evaluated the germination potential of seeds from eight peach tree rootstocks under different stratification methods, aiming at the production of high quality seedlings. In the first experiment, seeds with endocarp from eight genotypes (‘Aldrighi’, ‘Capdeboscq’, ‘Flordaguard’, ‘Okinawa’, ‘Okinawa roxo’, ‘Tsukuba 1’, ‘Tsukuba 2’, ‘Tsukuba 3’) were stratified on sand and moist vermiculite, at 7 ºC for 60 days. In the second experiment, endocarpless seeds of the same genotypes were stratified on Petri dishes at 7 ºC. In the third experiment, the time at which at least 75% of the seedlings reached transplanting height (15 cm high) was verified. The endocarp was a limiting factor for seed germination of the eight rootstocks, since the highest germination percentages were 21% and 48.3% for ‘Aldrighi’ and ‘Capdeboscq’, respectively. Germination of ‘Okinawa’ was only 19.2% and 4.2%, in sand and vermiculite, respectively. Seeds stratified without the endocarp, showed 100% germination, except for ‘Flordaguard’ and ‘Tsukuba 2’ and 3’, with 93% germination. Seed mass presented a positive correlation with the germination speed index and the initial growth of the seedlings. ‘Aldrighi’ and ‘Capdeboscq’ presented more vigorous seedlings with greater growth in height, stem diameter, and Dickson quality index.

The introduction of an automated control system on the production line of the rubber compound will reduce the influence of the human factor on the quality of rubber products, which will lead to a significant improvement in the operational and physico-mechanical characteristics of the final product. Also, the development of this system will create a centralized data collection system for creating reports on technological operations of the production process. To obtain high-quality products, it is necessary to control and maintain all technological parameters during equipment operation at the same level, modern means of registration and parameter management. In the production of rubber compounds, it is necessary to ensure a high degree of automation of the main technological equipment, which will make it possible to more accurately dose the ingredients, including dusting ones, to conduct the process in a given temperature regime for the time required to obtain high-quality products. The implementation of automatic control during the use of high-performance equipment is not possible without the use of measuring and control equipment. The article is devoted to the problem of automation of a system for measuring technological parameters on a rubber compound production line in order to improve the quality of manufactured products. The analysis of the technological process is carried out, the controlled parameters of not only the modes of the technological process, but also of raw materials, semi-finished products and finished products are selected. The choice of instruments and local automation equipment is presented, as well as the choice of an industrial microcontroller with which control is carried out at the lower level of an integrated automation system. A functional diagram of the automation of the rubber compound production process is proposed, which will allow to obtain a product with quality indicators corresponding to the regulated level.

Due to its structural and organoleptic functions, sucrose is one of the primary ingredients of many baked confectionery products. In turn, the growing awareness of the association between sugar overconsumption and the development of chronic diseases has prompted the urgent need to reduce the amount of refined sugar in foods. This study aimed to evaluate the effect of complete sucrose replacement with inulin-type fructans (ITFs), namely fructooligosaccharide (FOS), inulin (INU) or oligofructose-enriched inulin (SYN), with different degrees of polymerization on the technological parameters and sensory quality of gluten-free sponge cakes (GFSs). The use of ITFs as the sole sweetening ingredient resulted in the similar appearance of the experimental GFSs to that of the control sample. In addition, all GFSs containing ITFs had similar height, while their baking weight loss was significantly (p < 0.05) lower compared to the control products. The total sugar exchange for long-chain INU increased the crumb hardness, while the crumb of the GFS with FOS was as soft as of the control products. The sensory analysis showed that the GFS containing FOS obtained the highest scores for the overall quality assessment, similar to the sugar-containing control sponge cake. The results obtained prove that sucrose is not necessary to produce GFSs with appropriate technological parameters and a high sensory quality. Thus, it can be concluded that sucrose can be successfully replaced with ITF, especially with FOS, in this type of baked confectionery product.

The article analyzes the results of heat resistance of cold-harmful mixtures with the addition of clay. The article presents the results of an experimental laboratory study of the properties of samples from CTS, obtained by various methods. The scientific novelty of the technology lies in the fact that the technology of casting in cold-rolled steel ensures high quality of the casting surface, the absence of gas defects and blockages in the casting. The selection of the composition and technological parameters for the manufacture of the mold, contributing to the production of high-quality defect-free castings, will significantly reduce their cost, which will have a positive effect on the economy of our country. The study of the change in density over time depending on the applied load was studied in a series of experiments. The density of the mixture was determined every thirty seconds during the entire time of the formation of the dispersed medium. These experiments showed that at the beginning of the formation of the shell, its density increases significantly. In works on the thermal stability of polymers, the general laws of thermal decomposition and carbonization of cyclic, spatially crosslinked hot curing polymers were investigated and it was shown that the kinetics of destruction, the composition of gaseous products, the amount of coke formed and its properties depend on the properties of the initial polymers - the degree of crosslinking of molecular chains, chemical structure, the presence of impurities of catalysts and other curing conditions, as well as the heating conditions - speed and temperature. The article summarizes some of the results of the study, which is most appropriate for thin-walled steel castings to use the following mixture composition: filler - quartz sand; binder - clay of the Kazakhstani deposit, epoxy resin, hardener.

The Relationship

<p class="Textoindependiente21">This article examines the factors that influence graduate valuations of the education/training they received at university in terms of its utility or applicability in the workplace. Drawing on the 2014 survey conducted by the Agency for the Quality of the Catalan University System, among students that graduated in 2010, we test three hypotheses. The first states that graduate valuation of the training received at university in terms of its utility for the workplace is higher among those who are currently employed in high quality jobs; the second that this valuation is higher among graduates employed in higher occupational categories; and, the third, that higher valuations are given by individuals with better academic records. The methodology used to test the three hypotheses is based on both descriptive and econometric techniques that allow us to control for specific individual characteristics and specific characteristics of the degree subjects studied. Preliminary empirical results allow us to verify two of the three hypotheses. The main contribution of this paper is to provide some initial insights into a relationship not frequently examined in the literature and to offer some empirical evidence that counters the typical “matching” standpoint taken on the relationship between education/training and level of employment.</p>
