In this experiment, colonies of six regional populations from the territory of the Republic of Serbia were included, and two generations (maternal colonies and their offspring) were observed. In two inspections (fall and spring), production traits and temperament were observed. Daughter queen bees mated in uncontrolled conditions (free-mating) in order to determine heritability of production traits in terms of practical beekeeping. The heritability coefficients (h2) for production traits calculated. It was found that the honey yield was mostly determined by genetic, but environmental conditions also had significant influence. Heritability for honey yield (h2) ranged from 72.72% (Rasina population) to 81.04% (Banat population). Colony strength was very dependent on external factors, but also from the very population. When it comes to food supply (honey and pollen), in the inspections, large differences in the heritability coefficient were determined, which is explained by the interaction of genetic factors (the foraging instinct) and environmental factors (honey flora and climatic conditions during foraging) and the influence of beekeepers (feeding, etc.).

Климатические условия на большей части территории Российской Федерации не позволяют выращивать виноград в открытом грунте, поэтому его завозят из южных районов страны. Производство виноградных напитков обычно сосредоточено в местах выращивания винограда, так как доставка готовой продукции в северные регионы сопряжена со значительными финансовыми затратами. В Республике Дагестан выращивают около 30% винограда в масштабах всей страны, а площадь плодоносящих виноградников занимает более 20 тыс. га. Возникла необходимость переработать виноград таким образом, чтобы полуфабрикат для изготовления напитков выдерживал длительные сроки хранения и транспортировку, отличался высоким качеством и имел небольшую массу. Разработана технология получения виноградных криопорошков, которые можно использовать в качестве пищевых добавок, для изготовления восстановленных соков и напитков. Целью исследования было создание инновационной технологии производства криопорошков для получения безалкогольных напитков. Объектом исследования стал виноград дагестанских технических, столовых и изюмных сортов. Алгоритм получения криопорошков соответствовал предложенной автором схеме: доставка винограда, отделение гребней, инспекция, мойка, дробление, замораживание жидким азотом, обезвоживание в вакуумной СВЧ-установке, криоизмельчение и фасовка. При выполнении работы определяли качественный состав сырья и криопорошков с использованием аналитических приборов и лабораторного оборудования кафедры технологии продуктов питания и учреждений Дагестанского научного Центра РАН. Определен химический состав криопорошков, полученных из винограда, выращенного в горно-долинной зоне Дагестана. Приведены физико-химические показатели напитка из криопорошка винограда. Органолептические показатели изготовленных виноградных напитков подтвердили их высокие качественные показатели. Climatic conditions in most of the Russian Federation do not allow growing grapes in the open field, therefore they are imported from the southern regions of the country. The production of grape drinks is usually concentrated in places where grapes are grown, since the delivery of finished products to the northern regions is associated with significant financial costs. Winegrowers of the Republic of Dagestan grow about 30% of grapes throughout the country, and the area of fruit-bearing vineyards occupies more than 20 thousand hectares. There was a problem to process grapes in such a way that the semi-finished product for the production of drinks withstands long storage and transportation periods, is of high quality and has a small weight. A technology has been developed for producing grape cryopowders, which can be used as food additives, for the production of reconstituted juices and drinks. The aim of the study was to create an innovative technology for the production of cryopowders for the production of soft drinks. The objects of the study were Dagestan common and raisin grapes. The algorithm for obtaining cryopowders corresponded to the scheme proposed by the author: delivery of grapes, separation of ridges, inspection, washing, crushing, freezing with liquid nitrogen, dehydration in a vacuum microwave unit, cryo-grinding and packaging. When performing the work, the qualitative composition of raw materials and cryopowders was determined using analytical instruments and laboratory equipment of the Department of Food Technology and institutions of the Dagestan Scientific Center of the Russian Academy of Sciences. The chemical composition of cryopowders obtained from grapes grown in the mountain-valley zone of Dagestan has been determined. The physical and chemical parameters of a wine drink made from grape cryopowder are given. The organoleptic characteristics of the produced wine drinks confirmed their high quality indicators.

Pollination studies involving zero, one and three colonies of honey bees per acre, on commercial alsike clover fields ranging in size from 15 to 75 acres, were conducted in 1954, 1955, and 1957 in the Hinton Trail district of the Peace River Region of Alberta. These studies indicated that in large fields one colony of honey bees per acre is sufficient to pollinate alsike clover, consideration being given to competition of other crops and to the climatic conditions. The influence of competing crops was such that 65- to 75-acre fields, with one colony per acre, were similar in honey bee populations and seed production to 15- to 20-acre fields with three colonies per acre. Competing plant species accounted for 15 to 36 per cent of the pollen collected by honey bees. Fields with the higher populations of pollinators matured earlier than fields deficient in pollinators. A population of 3400 honey bees per acre (0.7 bee per sq. yd.) throughout the flowering period resulted in seed sets up to 82 per cent and seed yields to 375 lb. per acre. Check fields, where no honey bees were supplied, ranged in production from 29 lb. per acre, with a low native pollinator count, to 293 lb. where a pollinator equivalent of 1300 bumble bees per acre was observed. Bumble bees worked alsike clover at the rate of 28.6 florets per minute, as compared to 20.0 for leaf-cutter bees and 18.7 for honey bees.

Immunohistochemistry using mouse retinal cryosections is a routine assay used in vision research. However, retinal tissues are fragile, and it is difficult to obtain an ideal retinal cryosection. Here, we developed a modified method for preparing retinal cryosection. Super Glue was applied on the surface of the sclera before the cornea and the lens are removed from either the unfixed or PFA-fixed mouse eyeballs. The new methods largely prevented retinal detachment in mouse retinal cryosections. Immunostaining of retinal cryosections derived from PFA-fixed mouse eyes using rod and cone markers yielded high-quality immunofluorescent images. Immunolabeling of retinal cryosections obtained from unfixed mouse eyes using a cilium-specific marker had improved orientations of photoreceptor connecting cilia. This new method substantially improves the morphology and immunostaining results of fixed and unfixed mouse eyes.

Grey mountain Caucasian bees are of great interest for the selection, as a valuable gene pool of different populations of this race is supported by high mountains and inaccessible gorges of Dagestan, while serving as an isolated mountainous natural breeding areas. The studies were conducted in three different climatic conditions of the republic: the plains, foothills and mountainous areas. In the area of natural dispersal of gray mountain Caucasian bees in Dagestan released several local populations and different backgrounds. Characteristics of the main morphological features of honey bees are the length of proboscis, wing and width of the third tergite and others. These features bees vary, depending on the habitat population. Numerous studies of Dagestan honeybees showed, that the longest proboscis inherent in bees of mountain zone (6.85 ± 0.03 mm). The plain bees have a smaller proboscis (up to 6.71 ± 0.01 mm), and in the foothills bees the proboscis occupies an intermediate position (from 6.69 ± 0.01 to 6.83 ± 0.01 mm). Two other peculiarities (wing length and the third tergite) are subject to variation, depending on the altitude above sea level.

В машинной технологии возделывания и уборки корнеплодов и лука одним из важнейших показателей качества, определяющего длительность хранения корнеплодов является наличие или отсутствие в закладываемом на хранение ворохе почвенных и растительных примесей. Невозможность отделения почвенных комков из вороха корнеплодов и лука обусловлена тем, что на большинстве уборочных машин применяют щелевые сепарирующие рабочие органы, при этом межпрутковое расстояние сепарирующего транспортера с целью исключения потерь корнеплодов выполнено меньше минимального размера сепарируемого корнеплода, что приводит к невозможности их очистки на сепарирующих рабочих органах уборочных машин, а, следовательно, к травмированию значительной части товарной продукции и потерям при хранении значительной части выращенного урожая. Современные технологии и технические средства уборки корнеплодов и лука не способны обеспечить получение качественной товарной продукции при минимальных трудозатратах, что обусловлено отставанием или отсутствием в разработке технологических основ, технологий и рабочих органов уборки корнеплодов и лука, позволяющие снизить или исключить содержание почвенных комков в товарной продукции в различных почвенно-климатических условиях. Следовательно, разработка средств механизации для уборки корнеплодов и лука, позволяющих снизить или исключить содержание механических примесей в товарной продукции в различных почвенно-климатических условиях представляет научную проблему, решение которой будет способствовать инновационному развитию внутреннего рынка сельскохозяйственной продукции, устойчивому положения России на внешнем рынке.In the machine technology for the cultivation and harvesting of root crops and onions, one of the most important quality indicators that determines the duration of storage of root crops is the presence or absence of soil and plant impurities in the pile to be stored. The impossibility of separating soil lumps from a heap of root crops and onions is due to the fact that on most harvesting machines, slotted separating units are used. The inter-bar distance of the separating conveyor is less than the minimum size of the separated root crop to exclude losses of root crops, which makes it impossible to clean them on the separating working organs of harvesting machines, and, consequently, leads to damage of a significant part of commercial products and losses during storage of a significant part of the harvested yield. Modern technologies and technical means for harvesting root crops and onions are not able to provide high-quality commercial products with minimal labour, due to the lag or lack of development of technological foundations, technologies and working units for harvesting root crops and onions, which can reduce or eliminate the content of soil lumps in commercial products in various soil and climatic conditions. Therefore, the development of mechanization tools for harvesting root crops and onions, allowing to reduce or eliminate the content of mechanical impurities in commercial products in various soil and climatic conditions, is a scientific problem, the solution of which will contribute to the innovative development of the domestic agricultural market, Russias stable position on the foreign market.

The river system of West Macedonia comprises the headwaters and western extent of the Aliakmon watershed.  This region has a unique and highly complex geologic history (Rassios, 2008; Rassios, 2011), many aspects of which can be inferred by examining conglomerate (river-cobble) formations in the region.  These formations contain all rock types found within the modern-day river basin, as well as some which are not found within today's basin.  River-deposited sediments and cobbles found along today’s Aliakmon and Venetikos River systems trace the courses of ancient river flows, and thus provide information about past climatic conditions and tectonic events.  The sediments making up conglomerate formations in the region are mature, containing cobbles which have been transported, consolidated, eroded and redeposited up to five times (Rassios and Grivas, 1998).  This recycling of cobbles leaves only the most durable rocks while softer rocks are destroyed via abrasion.  Prehistoric peoples availed themselves of this concentrated and convenient selection of high-quality stones for the purpose of fashioning tools and weapons.
