<p align="justify"><strong>Aims</strong>: The selection of cv. Merlot clones performed in the Grocka winegrowing region, Republic of Serbia, and the study of agrobiological and technological traits of three selected clones and Merlot standard.</p><p style="text-align: justify;"><strong>Methods and results</strong>: The selection of clones was done using the method of individual clone selection in four phases over 15-20 years (Cindrić, 2003). O.I.V. methods were used in determining the most important agrobiological and economic-technological traits of grapes. The results of studied traits of grape and wine suggest that the quality of the clones surpassed the quality of the standard. Although the highest values for most of the studied traits were obtained for clone 025, there was no statistically significant difference between the clones. Indeed, the significant distinction between the clones was obtained for total polyphenol content (TPC) and total anthocyanin content (TAC) in wines: the wine of clone 025 had the highest TPC and TAC values. According to the tasting scores, wines of the clones may be classified as "quality wines with geographical indications".</p><p style="text-align: justify;"><strong>Conclusion</strong>: The selected clones were characterised by good quality grapes and wines. Improved viticultural parameters, versus the mother vine, indicate the need for further research work on the chemistry of both grapes and wines, aiming to better understand the characteristics of the selected clones and their market potential. Significance and impact of the study: The development of new clones (namely 022, 025 and 029) of better quality than the mother vine will, in the long term, lead to the introduction of the best clone(s) in viticultural practices and production. Until today, the clonal selection of Merlot has not been done in the Republic of Serbia and there are no recognised clones.</p>

<p style="text-align: justify;"><strong>Aims</strong>: The research work aimed at creating and testing a method to evaluate vine performance of Sangiovese (VPS), in particular, a method able to predict the potential oenological result through a limited number of variables measured on the vines.</p><p style="text-align: justify;"><strong>Methods and results</strong>: A matching table was created on the basis of literature and the experience acquired over twenty years of research activity on Sangiovese vine and wine quality in Tuscany, which allowed the selection of eight viticultural parameters and three VPS classes. In order to validate the matching table, a specific experiment was conducted during the years 2002 and 2003 in 10 vineyards (selected from 7 farms) representative of the main soils and climates of the vine cultivation areas of the Province of Siena (Italy). The experimental results validated the proposed matching table through a non parametric statistical analysis. A multivariate regression analysis between wine sensory evaluation (score) and viticultural parameters significantly predicted wine quality even with only 4 grape parameters (<em>P</em> &lt; 0.05).</p><p style="text-align: justify;"><strong>Conclusion</strong>: It was possible to predict VPS by means of a matching table based upon eight simple viticultural parameters. The reliability of the wine quality prediction increased proportionally according to the number of viticultural parameters, but remained rather high (R<sup>2</sup> = 0.606) when taking into account only sugar content, sugar accumulation rate, mean berry weight, and extractable polyphenol index (EPI).</p><p style="text-align: justify;"><strong>Significance and impact of the study</strong>: It is now possible to predict the quality of Sangiovese wines with a few selected grape parameters. Because of the wide variability in soil and climatic condition of the viticultural areas of the Province of Siena, where the method was developed, and the strong climatic contrast between the years when the method was validated, the use of both matching table and multiple regression is recommended for VPS prediction in Mediterranean environments.</p>

The development of rational system of basic soil tillage results in formation of sufficiently high crop yields. A two-factor field experiment was carried out to address these issues when cultivating winter rape cultivars on light chestnut soils of the Primorsko-Caspian sub-province of the Republic of Dagestan. VEM (standard), Elvis and Meteor winter rape cultivars were studied in the experiment. The following methods of soil tillage were studied: real tillage (control), subsoil tillage. The research revealed that there was no significant difference in agrophysical indicators between the soil cultivation variants. Data on weed infestation of winter rape fields showed that the number of weeds and their weight increased significantly after subsoil tillage. At the budding stage, the number of weeds increased 2.1-fold compared to the control (real tillage), and the weight of weeds increased 1.88-fold. During flowering stage, these indicators were 2.2 times higher. The maximum yield in all variants of the experiment was formed by Elvis cultivar - 44.9 and 41.4 t/ha, respectively, which is more than VEM (standard) and Meteor cultivars by 20.4 t/ha (7.9 %) and 20.0 t/ha (8.7 %), respectively. The yield of Meteor cultivar in these variants was also high and amounted to 41.6 and 38.1 t/ha, respectively, which was higher by 11.5 and 10.4 % compared with the standard. The greatest increase in the fresh yield was provided by real tillage. On average, the yield increased by 8.7 % for varieties in comparison with subsoil cultivation. Elvis cultivar formed the best quality indicators, followed by Meteor cultivar.

This chapter applied the random sampling in selection of the subjects suffering with headache, and care was taken that they ensure to fulfill the International Headache Society criteria. Subjects under consideration were assigned the two groups of GSR-integrated audio-visual feedback, GSR (audio-visual)- and EMG (audio-visual)-integrated feedback groups. In 10 sessions, the subjects experienced the GSR and EMG BF therapy for 15 minutes. Twenty subjects were subjected to EEG therapy. The variables for stress (pain) and SF-36 (quality of life) scores were recorded at starting point, 30 days, and 90 days after the starting of GSR and EMG-BF therapy. To reduce the anxiety and depression in day-to-day routine, the present research work is shown as evidence in favor of the mindful meditation. The physical, mental, and total scores increased over the time duration of SF-36 scores after 30- and 90-days recordings (p<0.05). Intergroup analysis has demonstrated the improvement. EMG-audio visual biofeedback group also showed highest improvement in SF-36 scores at first and third month follow up. EEG measures the Alpha waves for the subjects after meditation. GSR, EMG, and EEG-integrated auditory-visual biofeedback are efficient in solution of stress due to TTH with most advantage seen.

Psychrotrophic and mesophilic lactic streptococci were isolated from commercial cultured buttermilk to determine their potential effect on the quality of this product. These isolates consisted primarily of Streptococcus lactis subsp. diacetylactis, with S. lactis, Streptococcus cremoris, and Leuconostoc spp. also being present. Psychrotrophic isolates of S. lactis subsp. diacetylactis were compared to mesophilic isolates in regard to their ability to grow and reduce diacetyl in acidified milk (pH 4.7) incubated at 7°C. There was no significant difference detected in the ability of the two groups to reduce diacetyl (P&lt;.05). The mesophilic isolates grew more rapidly in acidified refrigerated milk than did the psychrotrophs, indicating that the psychrotrophic isolates were more acid sensitive. The psychrotrophic isolates exhibited generation times of 9 to 11 h when grown in skim milk (pH 6.7) at 7°C. Both psychrotrophic and mesophilic strains of S. lactis subsp. diacetylactis could rapidly reduce diacetyl in refrigerated acidified milk. The results of this study suggest that procedures for selection of starter cultures for buttermilk manufacture should be improved.

The aim of this study was to develop gluten-free bread formulations based on small broken riceberry flour, by using different ratios of rice flour and xanthan gum. Small broken riceberry and rice flour could be classified as low in amylose content (15.70 g and 20.50 g/100 g dry matter for small broken riceberry and rice flour, respectively). Additionally, small broken riceberry flour contained a total phenolic and total anthocyanin content approximately 500 times higher than that of rice flour. The addition of increased amounts of small broken riceberry flour and xanthan gum resulted in darker coloured gluten-free bread. However, there was no significant difference regarding moisture and specific volume. The increase of small broken riceberry flour and xanthan gum also led to a significant increase in the firmness of bread crumbs. The sensory evaluation showed differences in flavour, texture and overall liking, since adding small broken riceberry flour tended to make gluten-free bread more favourable. Bread containing rice flour and small broken riceberry flour in the ratio of 30:70 and 1.0% xanthan gum was selected on the basis of the sensory quality. Moreover, such bread also contained high levels of total phenolic and anthocyanin content.

One of the ways to intensify the production of beekeeping products is selection. Bee breeding is not only one of the most important methods, but also the most economically efficient way to increase the productivity of bee colonies. Thus, the selection of bees and the implementation of its achievements into production are one of the most important and most effective directions for intensifying beekeeping. Research work was carried out under the project of program-targeted financing of the Ministry of Education and Science of the Republic of Kazakhstan on the topic "Development of technologies for effective management of the selection process in beekeeping." This article examines the characteristics of the morphometric indicators of honeybees in the Almaty region of the Republic of Kazakhstan. The material for the research was the specimens of worker bees from apiaries located in the Almaty region of the Devochkin farm, Panov farm, Kalinin Individual Entrepreneur, Adilgazy Individual Entrepreneur, Kashkimbaev farm. To carry out the study according to the method of A.B. Kartashev, 35 samples of bees were worked out. Changes in the parameters of the wings, including the cubital and dumbbell index, discoidal displacement by bee species: Central Russian, Carpathian, Italian and Carniolian honey bee, are considered. It was found that in Kalinin’s apiary morphometric indicators for the cubital index, the average value was 2,787%. As a result, the morphometric indices for the cubital index in bees of the IP Kalinin bee were 2.777%. Whereas in other farms, the average value was significantly lower for all indicators. Accordingly, the percentage of the cubital index was 7.42-17.36%, the dumbbell index was 6.77-11.81%, and the discoidal displacement was 32.91-47.37%. According to all indicators, it is clear that the Kalinin Individual Entrepreneur’s bee farm is superior to other bee farms in terms of morphometric data. This is due to the isolation of the beekeeping and out of reach of other bees, thus ensuring a low level of hybridization. The considered analysis of the species belonging to the entire apiary, as well as economically useful features, can significantly increase the efficiency of selection work in beekeeping.

Objective. The aim of this study is to determine the quality of accredited education on the topic of gender-based violence to health care professionals, health and professional associates in the Republic of Serbia. Methods. A search of a database of accredited continuing education programs published on the website of the Health Council of the Republic of Serbia for the period between January 2010 and July 2019. identified programs using the keywords "violence", "family" "gender-based". The ch2 test was used to examine the differences between the independent variables versus the dependent variable. Results. This study showed that two thirds of the training was intended for health care professionals, only while health care workers, health and professional associates were allocated for every seventh education. If the type of institution is observed, it can be noticed that twice as many programs are accredited by civil society organizations in relation to the number of programs accredited by health institutions. Considering the time period in which the programs are accredited, a trend of increasing number of programs can be observed. Among the accredited programs, national courses accounted for 42.6% of the accredited programs while every other program was free. There is a statistically significant difference between educations organized by different types of institutions in relation to the type and cost of education. Conclusion. Although in the observed period there is an increasing trend in the number of accredited programs dealing with gender-based violence, there is still room to improve the quality of continuing education in terms of increasing the number of trainings with an interactive method of work, trainings aimed at different profiles of health professionals and health and professional associates, as well as free on line trainings.

Roselle has a brilliant red colour, high in vitamins and has a unique flavour that makes it suitable for juice production. Meanwhile, Gum Arabic (GA) is the edible dried exudate attained from stem and branch of Acacia senegal that contains high dietary fibre which can serve as prebiotic. Therefore, the application of GA into roselle juice might promote health benefits to consumers. GA is categorised as hydrocolloid and its application might affect important properties and acceptability towards the product. Hence, this study was conducted to investigate the effect of different concentrations of Gum Arabic (GA, Acacia senegal) addition (0%, 2%, 4% and 6%) on physicochemical properties and sensory acceptability of roselle juice. Increasing the GA concentration resulted in increased pH, total soluble solids, viscosity and turbidity values of roselle juice (p<0.05). However, the addition of GA had reduced the total anthocyanin content in roselle juice. For colour analysis, the addition of GA significantly (p<0.05) reduced the redness (a*) and yellowness (b*) properties. There was no significant difference in all attributes for sensory evaluation except for colour attribute. In conclusion, the addition of GA up to 6% into roselle juice caused an increase in pH, total soluble solids, viscosity and turbidity, but no effect to the sensory attributes.

Present research work was designed to develop lassi from reconstituted milk using different levels of water. For this purpose, dahi was prepared from reconstituted milk using traditional starter culture. Four different types of lassi were prepared by mixing dahi with 15, 20, 25 and 30% water and sugar level in all samples were 20%. The quality of lassi from reconstituted milk was evaluated by a panel of expert judges by different physical tests using a score card. There was non-significant difference (p>0.05) among the overall physical score of lassi samples. Result revealed that the highest overall score was recorded in 20% added water lassi sample whereas the lowest score was found in 30% added water lassi sample. In chemical analysis, significant differences (p<0.01) existed among the total solids, carbohydrate, fat, protein, moisture content and pH value but non-significant differences (p>0.05) were seen for ash content and acidity percentage. The total bacteria, coliform, yeast and mold in all samples did not exceed the legal standard. From the findings of this study, it might be concluded that lassi could be prepared successfully from reconstituted and mixing reconstituted milk dahi with 20% water along with 20% sugar will produce better quality lassi.Bang.
