Relevance. The appearance on the market of water-soluble fertilizers, growth regulators, biological products requires a detailed study of these drugs to determine their effectiveness in increasing yields and optimizing costs. Therefore, the issue of developing environmentally friendly elements of the technology for growing varieties of table watermelon of different ripening periods with the use of new types and forms of water-soluble fertilizers becomes urgent.Materials and methods. The object of research is varieties of watermelon of domestic selection of early and medium ripening. The studies were carried out in 2018-2020 on the basis of the Bikovskaya cucurbits breeding experimental station (Bykovskiy district, Volgograd region). The methods of using the preparation Potassium Humate (liquid) were studied: Treatment of plants twice, Soaking the seeds before sowing. The passage of the main periods of plant growth and development, biometric parameters of plants, biochemical composition of fruits and productivity of table watermelon were determined. The purpose of the research: to determine the effectiveness of methods of using potassium humate (liquid) in increasing yields, to reveal their influence on the quality of table watermelon fruits of different ripening periods.Results. The experimental data obtained showed a fairly high efficiency of the use of humic fertilizer in the cultivation of table watermelon both in early-maturing varieties and in varieties of late ripening. The maximum yield of the late-ripening watermelon variety Ikar was obtained when using the preparation Potassium Humate for treating plants – 17.1 t/ha, which is 25.7% more than control. The same method of using the humic preparation was noted as the most promising in the early ripening variety of watermelon Triumph, where the yield exceeded the control values by 21.8% and the method of use was by 18.0% – soaking the seeds before sowing. Studies have determined that the use of the preparation Potassium Humate in the technology of growing table watermelon allows to obtain fruits of good quality with a content of nitrates significantly lower than the maximum permissible concentrations for this culture (MPC – 60 mg/kg).

При внедрении новых технологий можно добиться высокой рентабельности томата за счет повышения продуктивности культуры. Федеральным научным центром овощеводства и рядом других селекционных организаций создано множество новых сортов и гибридов томата. Цель исследований, проведенных авторами в 2019-2020 годах: оценка отзывчивости нового среднераннего салатного сорта томата Красный банкир отечественной селекции на капельное орошение и применение минеральных удобрений, анализ продуктивности и качества продукции, выращенной на обыкновенных черноземах в условиях Ростовской области на Бирючекутской овощной селекционной опытной станции – филиале ФГБНУ «Федеральный научный центр овощеводства». В 2019 году сорт включен в Госреестр по Российской Федерации для выращивания в открытом грунте и под пленочными укрытиями в ЛПХ. Была поставлена задача: за счет дифференцированного применения удобрений и орошения добиться стабильной урожайности томата до 100-120 т/га, без снижения качества продукции. В качестве корневых подкормок использовали раствор микрокристаллического водорастворимого удобрения «Мастер» с капельным поливом, листовые подкормки проводили вручную раствором органоминерального наноудобрения с ростостимулирующей активностью «Арксойл ККР» (концентрат коллоидного раствора). Авторами выявлена очень высокая эффективность применения основного удобрения и подкормок водорастворимыми удобрениями при возделывании культуры томата на обыкновенных черноземах в условиях капельного орошения, которые повышают урожайность плодов фактически в три раза (до 98-103 т/га, доля стандартных плодов 98%). Количество плодов на растении увеличилось более чем в два раза. Использование для корневой подкормки растений водорастворимого удобрения «Мастер» с различным соотношением питательных элементов по основным фазам вегетации увеличило урожайность томата на 15-21%. Применение изучаемых агротехнических приемов не ухудшало качество плодов томата, продукция экологически безопасна для потребителей. With the introduction of new technologies, self-sufficiency in tomato can be achieved by increasing the profitability of the crop. At present, the Federal Scientific Center for Vegetable Growing and a number of other breeding organizations have created many new varieties and hybrids of tomato. The purpose of the research conducted by the authors in 2019-2020 was to assess the responsiveness of a new medium-early salad tomato variety Krasnyi bankir of domestic breeding for drip irrigation and the impact of mineral fertilizers, to analyze the productivity and quality of products grown on ordinary chernozems in the Rostov region at the Biryuchekutskaya vegetable selection experimental station – a branch of FSBSI Federal Scientific Vegetable Center. In 2019, the variety was included in the State Register for the Russian Federation for growing in open ground and under plastic covers in private household plots. The task was to achieve a stable tomato yield up to 100-120 t/ha due to the differentiated application of fertilizers and irrigation, without reducing the quality of products. A solution of microcrystalline water-soluble fertilizer Master with drip irrigation was used as root dressings, foliar dressings were carried out manually with a solution of organo-mineral nano-fertilizer with growth-stimulating activity Arksoil KKR (colloidal solution concentrate). The authors revealed a very high efficiency of the use of the main fertilizer and topdressing with water-soluble fertilizers when cultivating a tomato crop on ordinary chernozems under drip irrigation, which increase the yield of fruits actually 3 times (up to 98-103 t/ha, the share of standard fruits is 98%). The number of fruits per plant has more than doubled. The use of water-soluble fertilizer Master for root feeding of plants with different ratios of nutrients in the main phases of the growing season increased the tomato yield by 15-21%. The use of the studied agrotechnical methods did not worsen the quality of tomato fruits, the products are environmentally safe for consumers.

In electronics assembly, the convection based soldering technologies in the production lines consumes massive resources and energy. The recent advancements in soldering technologies consume comparatively higher resources and needs to be optimized for resource efficient production which is also the motivation for the present work. This study is devoted to quantify the resource consumption and qualify this consumption through exergy flows in an over-pressure reflow technology as an energy intensive process in electronics manufacturing. The analysis implies on a big saving potential for energy consumption specifically during the over-pressure process which also defines the void reduction quality of solder joints. Exergy efficiency is the fraction of the work potential of the heat that is converted to work, and it illustrates the quality of consumed resources during the soldering oven process. Shortening the production lead-time, and increasing the production rate increase the efficiency of exergy and prevents wastage of usable energy. Furthermore, the set-up improvements for the temperature profiles are necessary, and the changes toward developing new technologies in pre-heating and over-pressure chamber zones are mandatory if a high efficiency of resources used is expected.

The accuracy of photogrammetric reconstruction depends largely on the acquisition conditions and on the quality of input photographs. This paper proposes methods of improving raster images that increase photogrammetric reconstruction accuracy. These methods are based on modifying color image histograms. Special emphasis was placed on the selection of channels of the RGB and CIE L*a*b* color models for further improvement of the reconstruction process. A methodology was proposed for assessing the quality of reconstruction based on premade reference models using positional statistics. The analysis of the influence of image enhancement on reconstruction was carried out for various types of objects. The proposed methods can significantly improve the quality of reconstruction. The superiority of methods based on the luminance channel of the L*a*b* model was demonstrated. Our studies indicated high efficiency of the histogram equalization method (HE), although these results were not highly distinctive for all performed tests.

The aim of the work is to research the chemical composition of surface watercourses in the Slavsky district of the Kaliningrad region in the winter hydrological season, and to compare the results with the data previously obtained by the authors for the autumn hydrological season and partly for the summer hydrological season. Watercourses and monitoring points for research have been identified: r. Zlaya, r. Shluzovaya, r. Nemoninka and r. Osa. In the winter season, water samples were taken, hydrometric characteristics were measured, and primary hydrochemical indicators were determined. On the basis of the obtained hydrochemical data, integral indicators were calculated to assess the quality of water, using combined lists of maximum permissible concentrations of pollutants. When monitoring hydrochemical indicators, it was revealed that the studied watercourses are, to one degree or another, subject to pollution. The water quality class in them varies from "moderately polluted" to "extremely dirty". When comparing the seasons, a tendency was revealed to improve the quality of water, which is associated with the water content of rivers, as well as with the cycles of natural and anthropogenic activity. The work has theoretical and practical significance. The data can participate in the planning of rational use of natural resources and the selection of measures to improve the geoecological state of the river network of the Slavsky region. The research can serve as a supplement to the formation of the general geoecological picture of the Kaliningrad region.

Relevance. The aim was to study the reaction of new potato varieties early ripening group Zabava and middle-ripening group Smolyanochka on the timing of planting and doses of mineral fertilizers for obtaining maximum yield of seed potatoes. As mineral fertilizers used azophoska, superphosphate and potassium chloride.Results. It was found that the variety Zabava compared to the variety Smolyanochka, had a higher stem-forming ability and exceeded the parameters of the stem in all variants of the experiment. This is due to the biological characteristics of the studied varieties, since the Zabava variety, unlike the Smolyanochka variety, had more multiple eyes on the surface of the tuber. Against the background of applying mineral fertilizers N60P72K90, the density of the stem was higher, compared with the background of applying N32P32K32 in both the Zabava variety and the Smolyanochka variety. It should also be noted that there was a tendency to reduce the stem at a later date of planting in all variants of the experiment. The percentage of viral diseases affected increased with later planting dates and was highest with the planting dates of 14 and 20 may. The highest yield of tubers of the seed fraction was obtained in the variant with a planting date of may 14 against the background of balanced doses of mineral fertilizers (N60P72K90) and amounted to 13.3 t/ha in the Zabava variety, 13.0 t/ha in the Smolyanochka variety. It should be noted that different backgrounds of mineral fertilizers did not have a significant impact on the percentage of potato tubers affected by diseases. At the same time, the incidence of tubers with diseases did not exceed the regulatory requirements of GOST R 53136 – 2008 "Seed potatoes. Technical conditions».

Brazilian education faces many challenges, among which as highlighted in this text, is the need to prepare future teachers with a scientific and humanistic foundation, without neglecting contemporary aspects such as new technologies. The Chemistry Licentiate Degree course offered in the DE modality by the IFMT has contributed towards training teachers of this subject to work in Basic Education. Thus, the objective of this study is to reflect upon the educational conjuncture and identify how the course scholars assess the training process they are receiving. The study is of a descriptive and exploratory survey type from a quantitative approach, that took place during February and March 2017, with 57 course scholars taking part. The data was collected through an electronic form sent via Google Drive that contained 5 Likert scale closed questions to analyze 44 aspects of this training process and its elements. The methodology applied to analyze the collected data was consensus analysis. The results from the calculated scores point that the course meets academic expectations, with the following aspects being best assessed: comprehension of concepts and the effort to perform the activities (such as self-evaluation), selection of the contents covered (referent to the trainers), quality of label information (referent to the VLE), videos (as didactic materials), and questionnaires (as evaluation instruments). The only aspect that received no positive consensus in the assessment were the chats. Therefore, the assessment of the early DE chemistry teacher training is one way of reflecting upon the challenges education faces in contemporary times. Keywords: Educational context. Early training. Training process.

Purpose – Conventional materials and procedures in worldwide construction sector is a paradigm that requires change. Constructors usually do not take the adventure of testing novel techniques and materials in their construction projects and, as a result, profits are usually given in terms of time and cost savings. The purpose of this article is to introduce a model to add aggregate value in eco-sustainable dwelling construction through ecological sustainable value chain and hypothesis settlement. Design/methodology/approach - A review of the literature was done in databases using keywords. The selection of sources includes scientific articles and case studies based on different methods and contexts which were carried out. Findings - The findings suggest the implementation of the training of both the employee who works in the construction and the client regarding selfsustainable construction. A significant improvement was obtained based on the commercial relations of suppliers, the client, and also with the construction company. Finally, innovation in at least one of the six proposed aspects was carried out: new technologies, including eco-technologies, the quality of materials (including the eco-sustainable ones), the segmentation of the demand for eco-sustainable housing and its new ways of marketing and financing. They were, however, proposed for added value generation for the development of eco-sustainable housing. Originality/value - A model for the generation of added value in the construction of eco-sustainable housing was elaborated based on the relationships between human and relational capital, training, and the generation of aggregate value.
