В статье представлены результаты трехлетних исследований по влиянию традиционных способов хранения на сохранность и качество клубней топинамбура. Полезные свойства топинамбура известны человеку на протяжении многих лет. В силу биологических особенностей использование клубней на протяжении всего календарного года довольно проблематичная задача они подвергаются грибковым заболеваниям, быстро усыхают. Поэтому целью данного исследования является определение оптимального, из традиционных способов, хранения в условиях овощехранилища. В большинстве лет исследований лёжкость топинамбура не зависит от способа хранения и изменяется от 31 до 95. Внешние наблюдения показали, что во второй год исследований наилучшую лёжкость обеспечил способ хранения клубней в мешке. В первый и третий год исследований во всех способах наблюдались загнившие клубни. Независимо от применяемого способа, клубни в процессе хранения подвергаются усушке. В большинстве лет исследований она выше при хранении насыпью на 1,7-8,2. При хранении клубней топинамбура в ящиках наблюдается наименьшее снижение содержания клетчатки 0,2-2,5, в то время как при хранении в мешке 1,1-4,3, при хранении насыпью 0,9-2,4. Хранение в ящике обеспечивало наименьшее снижение содержания водорастворимых сахаров 1,4-4,8. Наиболее оптимальным из традиционных способов является хранение в ящиках.The article presents the results of three years of research on the impact of traditional storage methods on the safety and quality of Jerusalem artichoke tubers. The beneficial properties of Jerusalem artichoke have been known for many years. Due to biological characteristics, the use of tubers throughout the calendar year is a rather problematic task - they undergo fungal diseases and quickly dry out. Therefore, the purpose of this study was to determine the optimal method of storage in a vegetable store. In most years of the research, the storability of Jerusalem artichoke did not depend on the storage method and varied from 31 to 95. External observations showed that in the second year of the research the best keeping quality was ensured by the method of storing tubers in bags. In the first and third years of the research, rotted tubers were observed under all methods of storage. Regardless of the method used, tubers were dried during storage. In most years of the research, moisture loss was higher when stored in bulk - by 1.7-8.2. When storing Jerusalem artichoke tubers in boxes, the lowest reduction in fiber content was observed - 0.2-2.5, while when stored in bags - 1.1-4.3, when stored in bulk - 0.9-2.4. Storage in boxes provided the smallest reduction in the content of water-soluble sugars - 1.4-4.8. The most optimal of the traditional methods of storage is the storage in boxes.

The aim of the research was to determine the impact of double-cut harvest system on yield, as well as on suitability of Miscanthus × giganteus biomass for ensiling and biogas production. Biomass was harvested at the end of June (harvest I) and at the beginning of October (harvest II, regrowth). A single-cut regime at the end of October was also conducted. Biomass from harvests I and II was ensiled and subjected to anaerobic fermentation. The total dry matter (DM) yield from double-cut harvest system was similar to the DM yield from one-cut harvest, but two harvests per year had a positive effect on chemical composition of the biomass. C/N ratio and lignin content in the biomass from harvest I was lower compared to the single-cut biomass. Double harvest biomass was susceptible to ensiling, however, the biomass from harvest I characterized by low dry matter and water soluble sugars content resulted in poorer quality of the obtained silage (butyric acid was present). There were no significant differences between the methane yields obtained from ensiled biomass from harvests I and II.

Relevance. One of the most important elements of the technology of cultivation of strawberries for increasing productivity and improving the quality of berries is the use of fertilizers that can regulate the growth, development, yield and quality of products.Methods. During 2016-2018, the impact of pre-planting application of complex mineral fertilizers on the yield and quality of strawberries in the Udmurt Republic was studied. The analysis of meteorological conditions during the growing season of the crop according to the research results is carried out.Results. The results of the use of complex fertilizers Azofoska, Perm-yagodnoye and Fusco-yagodnoye on garden strawberries when grown in the conditions of the Udmurt Republic are presented. It was found that the use of these fertilizers in comparison with the control (Azofoska) contributes to an increase in yield and has a positive effect on the quality of berries. The aftereffect of the studied fertilizers on the second and third year of fruiting of wild strawberries is noted. According to the results of research, the highest yield of berries of the garden strawberry was obtained in 2016 in the first year of fruiting when applying Chamfer-berry (1.33 kg/m2 ). The pre-planting application of the FaskoYagodnoye fertilizer provided a reliable increase in yield at all times of berry harvesting, and on average for three years by 0.13 kg/m2 with an NSR of 0.04 kg/m2 . The content of dry matter, water-soluble sugars and vitamin C in the berries corresponded to the characteristics of the Darenka variety and to a greater extent depended on the meteorological conditions of the growing season of strawberries.

Fungal improvement of the nutritive content of low-quality forages can be affected by several factors among which loss of water-soluble content (WSC) plays a major role. To achieve this aim, two growth conditions i.e. forage-liquid ratios (1:3 and 1:5) and two inoculation times (14 and 28 days) were used to cultivate the selected fungi i.e. Pleurotus ostreatus (PO) at 30°C and Ceriporiopsis rivulosus (CR) at 20°C on Brachiaria decumbens (BD), Andropogon gayanus (AG), Triticum aestivum (TA) straw, Lolium perenne (LP), respectively with the view of selecting the optimal conditions that facilitate the release of WSC. The impact that losses of WSC have on the ability of fungi to improve the nutritive content (i.e. proximate, fibre, secondary metabolites and total antioxidant content) of the forages were then measured using 2 filtering methods i.e. light pump filtering method (LFM) and free flow filtering method (FFM). The optimal conditions that supported increased th soluble was identified as 28th day for both fungi; forage-liquid ratio of 1:5 for both fungi in most of the forages except BD (CR) and BD & AG (PO). The LFM led to lesser or no improvement in the nutritive quality of the upgraded forages while the opposite was recorded with the LFM. The LFM as against the FFM produced upgraded forages with lesser reduction in NDF; similar or higher ADF and lignin contents; and similar reduction in secondary metabolites and TAC when compared with un-improved forages. It can be concluded that the fungal improvement of the nutritive content of low-quality forages was negatively affected by the loss of WSC. It is therefore recommended that fungal improvement of the nutritive quality of low quality forages should be carried out with methods or techniques that facilitates little or no WSC loss in the upgraded forages.

Realism is an important aspect of the virtual shooting range, which increases the quality of the shooting training conducted there. An important element of realism is the modeling of damage arising during the impact of the projectile on the target. This article concerns damage modelling in computer simulation systems. Using the Unity environment, example simulations of damage caused by projectile impact on basic construction materials have been performed. The obtained solutions have been analysed, with the results compared with those of real experiments; conclusions pertaining to the optimal method of modelling destruction in simulation systems meant for visualisation at virtual shooting ranges have been drawn.

Abstract The formation and storage of man-made waste of water-soluble ores creates a global environmental problem that entails changing landscapes in mining areas and environmental degradation. The involvement of man-made waste in a closed cycle of the production and technological chain makes it possible to reduce the impact of mining and processing on the environment. The use of non-waste (low-waste) technologies, in addition to reducing the environmental burden, allows you to expand the raw material base of the enterprise by replacing the traditional components of the backfill mixture with man-made waste from mining and processing enterprises. The possibility of replacing the traditional, specially extracted aggregate in the backfill mixture with industrial waste of water-soluble ores is experimentally proved. The possibility of creating a cementless backfill mixture is proved. The possibility of replacing the cement binder with magnesium-containing slags of the Chusovsky Metallurgical Plant was confirmed. It was found that the separate activation treatment of the components of the backfill mixture has a positive effect on its rheological properties and increases the strength of the joint mass. The use of lignosulfonate improves the quality of the mixture and the resulting mass. The development of a backfill composite from man-made waste makes it possible to implement the principle of organizing mining production, which provides for the use of intermediate products in cyclic production and excludes the formation of man-made waste of water-soluble ores.

This study aims at finding an acceptable storage method for three varieties of Maize grown in the Ashanti Mampong Municipality of Ghana. Survey and standard laboratory protocols were carried out to gather the necessary data for the study. The background study revealed that 18%, 13%, 24%, 15%, 12%, 8% and 10% of farmers store their maize by heaping on the floor, storing in cribs, conventional jute sack, plastic drum, clay pot, triple-layer hermetic bag and polypropylene respectively. The findings also indicated that moisture loss was reduced in the plastic drum and triple-layer hermetic bag after the four months of storage. The proximate composition of the stored produce showed that maize preserved better in the triple layer hermetic bag. It is recommended that the triple-layer hermetic bag should be extensively used in storing maize as it has the ability to reduce moisture loss, and also preserving the nutritional and market value of the produce stored in it.

This study assessed the impact of an elective for second-year students on cultivating compassion through complementary and alternative medicine practices including therapeutic touch and healing touch. Course participants completed demographic questions, precourse and postcourse questions about confidence and practice in compassion, and the Maslach Burnout Inventory. Those who completed the elective reported significant improvements in confidence, practice, and sense of personal achievement. For example, for the statement, “I am confident in being calm, peaceful and focused (centered) before and during patient encounters,” scores improved from 1.7 to 8.0 on a 10-point scale ( p < .01). Optimism about future practice improved from 5.5 before to 7.9 after the course ( p < .05). Scores significantly improved for confidence and practice of compassion and optimism about future practice. Such electives may improve desired skills and help reduce burnout. Additional research is needed to determine the impact of such electives on quality of care.

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 Serbia, alfalfa is the most important perennial forage legume that is grown at 180-200 thousand hectares. Except for the classic production of forage, alfalfa is very important for seed production. In our conditions Alfalfa seed are produced from the second cut of alfalfa. Higher seed yields are achieved in larger distances between rows. In this system of production first and third cut are used for fodder. This trial tests three different densities and four varieties in order to determine the impact on yield and quality of forage dry matter. In the year of establishment, cultivars from the treatment A1 achieved higher yields of dry matter for 2.3 t ha-1 in relation to the treatment A2. In the second year, yield was higher by 1.4 t ha-1, and in the third higher for 3.1 t ha-1. Treatment A1 compared to A3 treatment had a higher yield of 3.5 t ha-1 (52%). In the second year treatment A1 achieved higher yields of forage then treatment A3 for 3.8 t ha-1 (44%), and in the third year for 4.6 t ha-1 (56%). Cultivars were also significantly affected the yield of forage dry matter at all densities. Influence of density and variety to the chemical composition of forage and the content of macro elements in the forage had no significant effect.
