Flax Straw

The information on the structure of the areas cultivated with fiber flax in Russia in 2016-2020 is presented. The varieties of the Tomsk school of breeding occupy almost 30% of the total area under crops. The study was carried out in the flax-growing regions of Russia in 2001-2020. The technological value of flax raw material of the studied varieties of fiber flax for processing flax of various quality at flax processing enterprises was determined. The indicators for the total fiber yield, long and short fiber yield, long fiber number and short fiber number, and the combination of these features were studied. The efficiency of using the potential capabilities of the studied varieties in relation to the data of the State Variety Testing was established. According to the results of flax straw processing and the rating assessment of these varieties in relation to the best and worst ones, it was found that the following varieties can be referred to as the ones with low-quality flax straw: Tomsk 18 - by the yield of short fiber (24.9%), Tomsk 16 - by the number of long fiber (11.08 N), Tost - by the number of short fiber (3.42 N) and the complex of features (average rating index of 9.8 positions). The group of the best varieties for the total fiber yield includes Tomsk 18 (33.2%) and Tost (32.2%), for the long fiber yield - Tost (13.1%), for the short fiber yield (23.2%) and the number of short fiber (5.20 N) - Tomsk 18 (high-quality flax). None of the varieties presented fulfil the biological potential in the processing of flax straw under production conditions in terms of the total fiber yield and the yield of long fiber, established by the State Variety Testing. Its value for the varieties of the Tomsk school of breeding is 65.2-86.3% for the total fiber yield, 17.6-31.4% for the long fiber yield (low-quality flax straw), 77.7-94.2 and 30.5-52.2%, respectively (high-quality flax straw).

Winter wheat is the most important food crop, which has a significant share in the structure of the grain area of Russia. The production of high-quality wheat grain is limited by significant variation and sharp fluctuations of the soil-climatic and other factors both within the regions and through the years. All this negatively affects the amount of productivity and its quality. The development of new varieties with high productivity and at the same time high-quality grain and flour, regardless of growing conditions, is an urgent and present task for plant-breeding. The tasks in the selection work of the FSSP “Prikumskaya Experimental Breeding Station” to increase the adaptive traits were fulfilled due to the development of the new winter wheat varieties which combine better productivity and grain quality. In 2015–2016 the varieties ‘Kadril’, ‘Iridas’ and ‘Korona’ were given to the State Variety Testing. Due to the positive results of testing in the North Caucasus region the new variety ‘Iridas’ was included in the State List of Breeding Achievements in 2019. The variety was obtained as a result of individual selection from the hybrid population ‘Prikumskaya 140’ × ‘Kroshka’. During the years of the State Variety Testing (2017-2018) at the plots of the Stavropol Territory, the variety ‘Iridas’ showed productive advantages in the extremely dry and arid zones compared to the standard varieties ‘Grom’ and ‘Ayvin’ with an increase of 0.31–0.43 t/ha, respectively. The maximum productivity (10.79 t/ha) during the years of testing was obtained at the Stavropol SVTS. The variety’ Iridas’ produces large kernels with high baking characteristics. According to ARCVQE, quality indicators of ‘Iridas’ grain meet the standards for valuable wheat. The protein percentage in the grain is 13.0, gluten percentage is 30.4, IGD is 67.

In the comparative variety testing it was evaluated promising material of fiber-flax (Linum usitatissimum L.). The aim of the work was to identify the most valuable cultivar fiber-flax according to their  economic and biological characteristics, and adaptability to adverse environmental factors.  Valuable forms of fiber-flax on the main economically significant features were identified in the Smolensk region. The total length of the stem of A-11 and L-198 exceeded the standard S-108 by 8 - 10%. The duaration of the growing season in all studied varieties was 5 days longer than that of the standard variety.   L-198 exceeded the standard S-108, both in yield of flax straw and fiber content in the stem, the excess was 9 and 3%, respectively. The highest yield of flax seeds (0,58 t/ha) was also in L-198 (21% higher than in the standard). The yield of long fiber in the stem of this sample was 20,1%, which is 0,8% higher compared to the standard. The calculation of the economic efficiency of cultivation of the L-198 variety for fiber-flax seeds also showed its advantage over the S-108 standard.

  The article is devoted to the study of the chemical composition, physical and thermal-pfysical characteristics of damp apple pomaces and the identifying patterns of influence of drying temperature the functional composition and gel-forming ability of pectin. The research is aimed at obtaining initial data for the subsequent calculation of the main technological, hydro-mechanical, thermal, structural and economic characteristics of devices for drying the plant raw materials, ensuring the environmental safety and high quality of pectin-containing raw materials, the reducing heat and energy costs. As a result of the study of the thermal characteristics of apple pomaces, the critical points (temperature conductivity – 16.5 x 10-8 m2/s, thermal conductivity – 0.28 W/m K, heat capacity – 1627 j/(kg K)) at a humidity of 56 % are determined, which characterizing the transition from the extraction of weakly bound moisture to the extraction of moisture with strong bonds (colloidal, adsorption). It was found that the pomaces obtained from apples of late ripening have a higher content of solids (21-23 %), soluble pectin and protopectin (2.5-4.5 %). Dried pomaces obtained from apple varieties of late ripening contain up to 25 % pectin, which allow us to recommend them as a source of raw materials for the production of pectin. The optimum modes of preliminary washing of raw materials are offered, allowing to the remove the ballast substances as much as possible. It is established that when the drying temperature increases, the destructive processes are catalyzed: the strength of the pectin jelly and the uronide component and the degree of pectin esterification are reduced. The optimum drying temperature of damp apple pomaces is 80 0C, at which the quality of pectin extracted from the dried raw materials is maintained as much as possible. It is shown that the most effective for the pectin production is a fraction with a particle size of 3-5 mm, which allow us to extract up to 71 % of pectin from raw materials.

In this paper, an economical way for accurately determining weight-based short fiber contents in raw cotton and semi-finished slivers by utilizing special bilateral beard specimens and image processing was introduced. In the specimen preparation, cotton fibers were drawn by a manual device into a sliver, then the sliver was combed to form a bilateral beard specimen, and finally the bilateral beard was scanned to generate a grayscale image from which a relative fiber number curve was extracted. An algorithm for calculating the weight-based short fiber contents based on the curve was proposed. Five types of cottons were repetitively measured to investigate the robustness of the results of [Formula: see text] and [Formula: see text], with the weight ratio of fibers shorter than 12.7 and 16 mm, respectively. The results showed that measuring two bilateral beards for each sample could keep the error rate lower than 15%, while four specimens kept the error rate lower than 10%. Compared with AFIS Pro 2, this Image-based Bilateral Beard Method provided results with lower standard deviations and variable coefficients, signifying its analogous or better robustness. In addition, 37 samples from some of the world’s major producing areas were measured by this method and AFIS Pro 2, and a Bland–Altman analysis confirmed a good agreement between the results from the two methods. As only a manual fiber drawing device and an office scanner are needed, this Image-based Bilateral Beard Method is clearly a cheap approach for accurately determining the short fiber contents in raw cotton and semi-finished slivers.

В связи с увеличением числа преступлений террористической направленности разрешения требуют вопросы, связанные с обеспечением объектов (территорий) УИС инструментами антитеррористической защищенности, к которым можно отнести такие, как проведение организационно-практических мероприятий антитеррористической защиты объектов УИС, наличие соответствующей документации и ответственного должностного лица, выполнение режимных требований на объектах УИС в соответствии с законодательством РФ, а также обеспечение контроля за количественными и качественными характеристиками эксплуатируемых инженерно-технических средств охраны и надзора. Актуальность проводимого исследования обусловлена необходимостью качественной реализации в правоприменительной практике совокупности требований обеспечения мероприятий по обеспечению антитеррористической защищенности объектов (территорий) УИС с целью защиты прав и интересов всех субъектов уголовно-исполнительной системы от террористического посягательства. Авторами выявляются проблемы правового и организационного уровня при оценке состояния антитеррористической защищенности объектов УИС: формализм при проведении обследований, недостаточный уровень оснащенности объектов УИС инженерно-техническими средствами охраны и надзора, а также финансирования для удовлетворения нужд объектов УИС в части обеспечения антитеррористической защищенности. Помимо прочего упоминаются такие проблемы, как отсутствие унифицированных принципов организации деятельности комплексных комиссионных обследований, разработанных с учетом современных правоприменительных норм и запросов практики, а также обосновывается необходимость повышения компетентности сотрудников ФСИН России при проведении комплексных комиссионных обследований. In connection with the increase in the number of terrorist crimes, the resolution requires issues related to the provision of facilities (territories) of the penal system with anti-terrorist security tools, which include such as the implementation of organizational and practical measures for the anti-terrorist protection of the penal system, the availability of appropriate documentation and a responsible official, the implementation of regime requirements at the facilities of the penal system in accordance with the legislation of the Russian Federation, as well as ensuring control over the quantitative and qualitative characteristics of the operating engineering and technical means of protection and supervision. The relevance of the study is due to the fact that in law enforcement practice, a high-quality implementation of the set of requirements for ensuring the anti-terrorist protection of objects (territories) of the penal system is required so that the rights and interests of all subjects of the penal system in terms of protection from terrorist encroachment are observed. The authors identify the problems of the legal and organizational level when assessing the state of anti-terrorist security of penal facilities: formalism in conducting surveys, insufficient equipment of penal facilities with engineering and technical means of protection and supervision, as well as the level of funding to meet the needs of penal facilities in terms of ensuring anti-terrorist protection. Among other things, such problems as the lack of unified principles for organizing the activities of complex commission surveys, developed taking into account modern law enforcement norms and practice requests, are mentioned, as well as the need to improve the competence of employees of the Federal Penitentiary Service of Russia when conducting comprehensive commission surveys is substantiated.
