The increased air temperature combined with the reduction of rainfall during hot season impairs the capacity of cows to maintain the optimal body temperature. This study tested the hypothesis that climate changes affect the medium yielding cows in temperate continental climate. The productive-reproductive parameters of 8607 milking cows from a dairy farm in North-eastern Romania were examined and correlated with changes in ambient temperatures and rainfall between the years of 1983 and 2010. We observed that the number of artificial inseminations served to cows showed a decreasing trend. The reduction in this parameter was significantly influenced by the increase in the average and maximum temperatures during hot season associated with the reduction in rainfall, as shown by regression analysis. Other studied parameters such as milk production, calving to conception interval, calving to first artificial insemination interval and conception rates at first, second and more than two services were not related to the changes in average annual temperatures, annual temperatures amplitude and annual precipitation quantities. This study suggests that, although present, the effects of climate changes on some productive-reproductive parameters of medium yielding cows in geographic areas with temperate continental climate are not as dramatic as described in other studies.

Топинамбур ценная культура, используемая в различных отраслях. Цель исследований: оценка адаптивности сортов топинамбура Файз-Барака и Мужиза к условиям жаркого сухого климата и засоленных почв, а также разработка важнейших элементов технологии для получения урожая в экстремальных условиях. Климатические условия характеризуются резко континентальным климатом, очень жарким летом и холодной зимой. В Кегейлинском районе, где проводились испытания, незначительное количество осадков в весенний период (510 мм), их отсутствие в летние месяцы и постоянный ветер способствуют низкой относительной влажности воздуха (1128) и засушливости. В летний период температура днем повышается до 4043 C, что вызывает стресс у всех произрастающих культур. Почвы участка, где проводили исследования-лугово-аллювиальные, легкосуглинистые, слабозасоленные, тип засоления-хлоридно-сульфатный. В пахотном горизонте содержание гумуса составляет 0,871,03, валового азота 0,100,12, фосфора 0,230,28, калия 2,52,7 мг/кг, а обменного калия 197305 мг/кг почвы. В период вегетации соли постепенно поднимаются в корнеобитаемый слой и на поверхность почвы, что отрицательно влияет на рост и развитие культур. Агротехнические мероприятия включали промывку почвы от солей в зимний период водой (35004000 м3/га), вспашку, боронование, нарезку борозд, две культивации в период вегетации, внесение минеральных удобрений общей нормой N100P150K100 (д.в.), 34 полива с нормой 600650 м3/га. Факторы и варианты опыта: два сорта топинамбура при четырех сроках посадки клубней, трех схемах посадки, трех фракциях массы клубня и трех вариантах глубины посадки. Каждый опыт закладывали в четырехкратной повторности рендомизированным способом. Площадь делянки каждого варианта опыта составляла по 55 м2. Использовали стандартные методики. При оптимальном сроке посадки клубней 5 апреля, клубнями массой 4060 г на глубину 910 см по схеме 7040 см обеспечивается наибольшая урожайность у сорта Файз-Барака (2,79 кг/м2) и Мужиза (3,02 кг/м2).Jerusalem artichoke is a valuable crop used in various branches of industry. The goal of the research is to assess the adaptability of Jerusalem artichoke Fayz-Baraka and Muzhiz cultivars to the conditions of hot dry climate and saline soils, as well as to develop the most important elements of the technology for obtaining a yield in extreme conditions. Climate conditions are characterized by a sharply continental climate, very hot summers and cold winters. In The Kegeyli region where the tests were conducted, the low amount of precipitation in the spring (510 mm), their absence in the summer months and constant wind contribute to low relative humidity (1128) and dryness. In summer, the daytime temperature rises to 4043 C, which causes stress for all growing crops. The soils of the area where the research was carried out are meadow-alluvial, light-loamy, slightly saline, and the type of salinity is chloride-sulfate. In the arable horizon, the humus content is 0.871.03, gross nitrogen 0.100.12, phosphorus 0.230.28, potassium 2.52.7 mg/kg, and exchange potassium 197305 mg/kg of soil. During the growing season, the salt gradually rises in the root layer and on the soil surface, which negatively affects the growth and development of crops. Agrotechnical measures included washing the soil from salts in winter with water (35004000 m3/ha), plowing, harrowing, cutting furrows, two cultivations during the growing season, applying mineral fertilizers with a General norm of N100P150K100 (act. subst.), 34 watering with a norm of 600650 m3/ha. Factors and experience options: two varieties of Jerusalem artichoke with four terms of planting tubers, three planting schemes, three fractions of the mass of the tuber and three options for planting depth. Each experiment was laid out in a four-fold repetition in a rendomized way. The plot area of each variant of the experiment was 55 m2. We used standard methods. The optimal term for tubers planting on April 5, planting tubers weighing 4060 g to a depth of 910 cm according to the 70x40 cm scheme provide the highest yields for the variety Fayz Baraka (2.79 kg/m2) and Mujiza (3.02 kg/m2).

Background. The barley collection at the N.I. Vavilov AllRussian Institute of Plant Genetic Resources (VIR), being the main source of source material for breeding, is insufficiently studied under conditions of extreme continental climate. The purpose of the research was to assess the adaptability of barley cultivars held by VIR to extreme continentality.Material and methods. The research targets were 24 barley cultivars representing various breeding centers and tolerance regions of Russia. The cultivar ‘Omsky 91’ developed at Omsk Agrarian Scientific Center was used as the reference.Results and discussion. According to the genetic profiles for alleles of hordein-coding loci, provided by the Vavilov Institute of General Genetics, more than 70% of the studied barley cultivars (‘Chelyabinsky 99’, ‘Priazovsky 9’, ‘Zadel’, ‘Sokol’, ‘Zernogradsky 584’, ‘Zadonsky 8’, ‘Khadzhibey’, ‘Beatrice’, ‘Knyazhich’, ‘Zevs’, ‘Kazak’) were linear in their hordein-coding loci. The homeostasis of the cultivars, their stability indices and plasticity levels were calculated. Their intensity measures and selection differentials were determined.Conclusion. The adaptability assessment based on the sum of ranks (calculated using the abovementioned adaptability parameters) showed that the monomorphic cultivars ‘Priazovsky 9’ and ‘Chelyabinsky 99’ as well as cv. ‘Severyanin’ (not listed in the State Register for Selection Achievements) were most adapted to extreme continental climate conditions (sums of ranks ranged from 8 to 29). The adaptability of the identified cultivars was confirmed by high-yielding hybrid populations produced from crossing the selected adaptable cv. ‘Chelyabinsky 99’ with cvs. ‘Omsky 91’ and ‘Omsky 95’ released by Omsk Agrarian Scientific Center. The obtained lines demonstrated higher yields than both the mean yield of the parent cultivars (+1.20 t/ha) and the yield of the best parent cultivar (+0.76 t/ha).

People have shared the geography they located in with animals since ancient times. Within this symbiosis, people have benefited from animals that they are in continuous interaction in various areas. Central Asia steps is a region that has harsh continental climate with cold winters and warm summers. Migrant settlers in this region, with a limited agriculture potential, live off animal husbandry. Feeding of herd and the need for managing this duty in a safe way pave the way for sheepherding. Shepherd’s felt cloak and fur used by shepherds against the unfavorable weather conditions are the primary symbols of shepherd culture due to their important functions. Worn by shepherds in order to be protected against the unfavorable climate conditions, felt cloak defined as sleeveless clothing made up of felt are considered with the concept of felt. Similarly shepherd’s fur, which is made up of peltry of sheep and lamb, and has a similar function with felt cloak, is one of vital clothing materials of shepherds. As a natural result of animal breeding, which is one of the indispensable elements of the nomadic lifestyle, with the transition processes of people to the settled order and accordingly agricultural production as well as the breeding of animals they have tried to hunt, the shepherd profession, which is obliged to meet all kinds of needs of animals, has emerged. In this study, it is aimed to give information about the development and importance of shepherd, about dandruff and shepherd's fur, a clothing specific to shepherds. The information obtained from the written and virtual sources related to the subject and the interviews made with the source persons were tried to be transferred. It is important to emphasize the process of making a garment a cultural carrier.

Kinship and genetic diversity determination among six rose varieties from the Grandiflora group were carried out using ISSR thechnics. The studied varities were divided into 3 clades: I) ‘Lezginka’, ‘Queen Elizabeth’ and ‘Koralovy surpriz’ varieties; II) ‘Gurzuf’ and ‘Love’ varieties; III) ‘Komsomolsky ogonek’ variety formed a separate branch. This division into clades was confirmed by a statistical comparison of morphometric characters. On the basis of the obtained data, it can be concluded that the analysis using the selected primer group is well-suited for differentiation rose varieties into groups, which makes it possible, for one thing, to determine the genetic distance between varieties, and for another, to use these data in the future by certification of the varieties promising by resistance characters to the continental climate conditions.

Opaque ventilated façades (OVFs) are increasingly gaining in importance in the design of sustainable buildings, given that they can lessen the building´s environmental impact. Opaque ventilated façades can reduce thermal gains in hot climate zones, improving the thermal comfort indoors, and reducing air conditioning demand. Nevertheless, the thermal behaviour of the opaque ventilated façade depends on the climatic conditions and the building´s specific design. This study analyses the effect of opaque ventilated façades in office buildings using 30 constructive configurations under eight tropical climate conditions. The study considers three options for the external layer of cladding (ceramic, stone, and aluminium composite material) and two configurations for the inner layer (plasterboard with mineral wool and ceramic). Simulations were carried out using the software tools TRanNsient SYstem Simulation program (TRNSYS) and TRNFlow. The model developed considers bioclimatic characteristics, including solar radiation and wind conditions for each climatic zone. The operating temperature was selected from within the range established by occupant comfort regulations. The findings suggest that it is possible to select the best office building opaque ventilated façade configuration for each of the specific climate conditions in Brazil.

Monitoring and dealing with particular conditions related to relative humidity (RH) and temperature within different cultural objects including post-byzantine churches are of primary importance for the current conservation and advancement. The objective of this paper is to explore and discuss how standards can be implemented and guide the decision processes in order to facilitate a sustainable management of cultural buildings. Following the particularities of the interface of Mediterranean and continental climate conditions, here is introduced a general climate risk assessment method, which determines how indoor climates fit into the selected post-byzantine cultural objects in Albania. A relative humidity over 75% and temperature frequently over 30°C within several churches is been assessed as a high risk of sudden or cumulative mechanical damage to most artefacts and paintings because of high humidity. Predicting preservation is an important aspect in preventing damage to objects. This paper also describes the historical and scientific background to the current discussions.
