The paper presents an analysis of the possibility of growing remontant type raspberry varieties in an annual culture in the climate of the northern regions, which solves the problem of shoots overwintering, both in decorative gardening and industrial plantings. The first stage of research in the collection nursery in the experiment on five remontant raspberry varieties regarding the requirements for soil and climatic conditions, resistance to diseases and pests, growth characteris-tics and individual development allows us to assess the development features of remontant raspberry varieties in the conditions of the Komi Republic. The collection nursery of remontant forms of raspberries of the Institute of Agrobio-technologies of the Federal Research Centre, Komi Science Centre, Ural Branch, RAS, was founded in 2018 and is represented by 5 varieties: Ruby necklace; Firebird, Elegant, Orange miracle, Hercules (St.). The studies were carried out according to the provisions of the standard method of field experiment during the growing seasons of 2018-2019. Agrometeorolo-gical conditions in 2018 were favorable for raspberry plants, in contrast to 2019. The unfavorable bal-ance of heat and humidity in the growing season of 2019 caused the end of the development of remontant raspberries at the stage of vegetative growth (Hercules variety) or flowering phase (4 varieties). Variety Orange miracle in the condi-tions of the Komi Republic is more susceptible to the risks of developing mycoses and damage by shoot gall midge. According to the results of two years of research, the Ruby Necklace variety showed good results in the formation of a certain number of shoots, resistance to pests and diseases, and the general condition of plants.
Coccidiostatics are used in poultry farms to prevent and treat eimeriosis, and antibiotics are used to reduce pathogenic microflora, which negatively affects the gut microbiome of birds. In some poultry farms, probiotics are used to correct the gut microbiome of birds with eimeriosis. The use of prebiotics for this purpose has been little studied, although they can also serve as an alternative to antibiotic therapy. The work is devoted to studying the effect of combined and separate administration of chemical coccidiocide and lactulose-containing prebiotic to broilers on the intensity of eimeriosis invasion caused by Eimeria tenella, as well as on the number of mesophilic aerobic and facultative anaerobic microorganisms, including bacteria of the genus Bifidobacterium, Lactobacterium, Clostridium and Escherichia in cecum of 28-day-old broilers. The results showed that on average, for the entire period of the experiment, the lowest intensity of eimeriosis invasion was in the groups where coccidiocide and prebiotic were used: 17.50 ± 5.91 and 17.32 ± 5.67 thousand oocysts/g respectively. In the group where their combined purpose was, the intensity was 27.41 ± 8.13, which was slightly lower than in the infected control - 29.21 ± 8.70 thousand oocysts/g. The introduction of a prebiotic into the broiler diet allowed increasing the number of native bacteria of the genera Bifidobacterium and Lactobacterium, which reduced the number of opportunistic microorganisms such as Escherichia and Clostridium.
Методика описания образовательных и научных сервисов в информационнообразовательном пространстве на базе стека интероперабельности EIF В данной статье представлена методика описания научных и образовательных сервисов в информационно-образовательном пространстве на базе стека интероперабельности EIF (European Interoperability Framework, сокр. EIF), описаны параметры, характеризующие сервисы на каждом этапе методики, средства, применяемые для описания как самих сервисов, так и используемого контента, а также определена связь методики описания с жизненным циклом сервиса. Приводится пример описания сервиса согласно методике с учетом существующих образовательных и профессиональных стандартов, рекомендаций ITIL, онтологии на базе OWL и WSDL-описания.
Проведен анализ весовых и размерных характеристик частиц взвешенных веществ в образцах снега с различных участков вблизи угледобывающих предприятий, расположенных в Алтайском районе Республики Хакасия. Точки отбора проб снежного покрова располагались в окрестностях населенных пунктов с. Аршаново, с. Белый Яр и районе автодороги, по которой транспортируется уголь, в соответствии с розой ветров. Анализ размера частиц проводили с помощью прибора «Ласка-ТД». Было установлено, что масса загрязняющих веществ, аккумулирующихся на снежном покрове, для территории в окрестностях с. Аршаново имела более высокие значения в сравнении с с. Белый Яр. При этом для с. Аршаново разница между минимальным и максимальным значениями массы пылевых частиц -240 раз, коэффициент вариации -1,62. Для Белого Яра разница между крайними значениями составила 9 раз, коэффициент вариации -0,51. Определено, что в исследуемых образцах основная доля взвешенных частиц, независимо от точки исследования, имела размеры от 5 до 20 мкм. Полученные результаты исследования позволяют сделать заключение о наличии в снежном покрове большого количества мелкоразмерной пыли, способной накапливаться в окружающей среде и негативно влиять на ее биологическую составляющую, в том числе и человека.
