A new method for determining the location of artificial hydrogeological windows in the roof and base of the aquifer has been proposed. As an example, the Buchak-Kaniv aquifer is given. This aquifer is widespread in the north-eastern part of Ukraine and is the main source of water supply for the region. In our opinion, pollution of the Buchak-Kaniv aquifer can occur primarily through artificial hydrogeological windows in its roof and bottom. In order to determine the location of artificial hydrogeological windows, factor analysis of the chemical composition of groundwater aquifer is used. The analysis was first carried out in places where it is precisely known about anthropogenic contamination of the aquifer with oil products and associated waters through artificial hydrogeological windows (for example, oil or other wells). As a result, a number of influential factors weighing more than 10% were identified. Further, in other areas factor analysis is also carried out using the same set of components of the chemical composition of groundwater. The coincidence of influencing factors indicates the theoretical possibility of an artificial hydrogeological window in a given area. In addition, various options for the distribution of pollutants over the horizon area are considered. The identification of these windows is important for identifying sources of aquifer pollution. Especially attractive will be the use of this method in areas where old (working and closed) oil, gas and oil-gas condensate fields are located.

On June 7, 2018, a sub-mesoscale anticyclonic eddy induced by the wind (north-east) was registered on the shelf in the area of the city of Gelendzhik. With the help of field multidisciplinary expedition ship surveys, it was shown that this eddy exists in the layer above the seasonal thermocline. At the periphery of the eddy weak variability of hydrochemical parameters and quantitative indicators of phytoplankton were recorded. The result of the formation of such eddy structure was a shift in the structure of phytoplankton – the annual observed coccolithophores bloom was not registered.

Assam is a state of the North Eastern part of India. There are varieties of plants distributed in various parts of the state. 50% of India’s entire plant biodiversity is contributed by the North Eastern States i.e., Manipur, Mizoram, Sikkim, Tripura including Assam. The Ministry of Environment and Forests (MoEF), Government of India in 1980s recorded two hundred and eighty-six (286) species of plants from Assam, used by the tribes of Assam.The traditional system of medicine plays an important role in the healthcare of rural people for all types of ailments. The healing power of traditional herbal medicines has been realized and documented since Rigveda and Atharvaveda. Nearly 80% of the world populations rely on traditional medicines for primary health care, most of which involve the use of plant extracts.

The study of coinage and economy of any area has its own appeal. As they are not much affected by outline influence, so they often proceed along their own lines and thus can have significance for people trying to determine the general patterns of development. In precolonial phase of Indian history, the Ahom kingdom situated in the North-Eastern part demands special attention as it had its own glorious series of coinage. As a royal issue, the coins of Ahom kingdom were the emblems of royalty and symbolic majesty of the Ahom kings. The metals, the motifs as well as other accompanying details on the coins depict the details of faiths and customs adopted by the Ahom kingdom. In this write up, we will discuss the origin, growth, importance in contemporary economy and many other aspects of the Ahom coinage in a comprehensive manner.

Introduction: The work has been attempted to detect and genetically characterise the nature of Bovine Viral Diarrhea Virus (BVDV) isolates from the porcine population of the north east. Methods and Material: The samples have been collected over a two year period and are from areas where there is a mixed and integrated rearing of livestock in close proximity. The isolates were identified, cloned and sequenced using BVD specific genomic primers for two important domains viz., E-2 and 5’ UTR. Results: Porcine BVD Sequences were analysed phylogenetically. Divergence in 3 sequences is noted in the 5’ UTR region that are forming a clear outlier group while E-2 sequences are coming close to BVDV group but forming a separate cluster.

The present communication deals with a calc-silicate hornfels of uncommon mineralogical and chemical composition. It may be tentatively referred to the deep-seated metamorphism of a marl, and on account of the shortage of analytical data pertaining to metamorphosed sediments of the calcareo-argillaceous type, a detailed investigation of a variety of this group seems justified.Intercalated bands of anorthite-epidote-garnet-hornfels bordered bilaterally by pyroxene-bearing gneisses occur on the farms Zandfontein, Pella, and Klein Pella in the north-eastern part of the division of Namaqualand, South Africa (cf. geological map), On Klein Pella small exposures also extend intermittingly for approximately 1·5 miles due WNW.-ESE. of the amphibolite koppie situated on the northern boundary of the farm area. The bands exhibit a gentle pinch and swell structure with maximum widths of 15 to 41 inches, and the contact with the host rock is commonly marked by an epidotic fringe ¾ inch in thickness. In some cases the anorthite-epidote-garnet-rock is penetrated by parallel lenticles of pure quartz which may attain maximum breadths of 0·8 inch.

В Северо-Восточной части Приволжского федерального округа традиционно выращивают вегетативно размножаемые формы лука. Период активной вегетации растений составляет 106–176 дней, а сумма температур выше 10 °C – 1600–2400, что ограничивает семенное размножение луковых культур. В последнее время растет спрос товаропроизводителей на посадочный материал шалота. Его возделывание по трудоемкости превышает обычный репчатый лук и требует определенных навыков в работе. По своим же пищевым показателям он всегда будет иметь спрос у потребителя. Цель работы – изучить вегетативный и семенной способы размножения лука шалота в условиях Кировской области. В статье обобщены результаты исследований с северной группой шалота за 2001–2020 годы, проведенные лабораторией северного овощеводства ВНИИО – филиала ФГБНУ ФНЦО в Кировской области. Опыты закладывали на дерново-подзолистой, хорошо окультуренной почве, овощного севооборота. Погодные условия были разнообразными: от типичных для зоны – по большинству лет исследований, до аномально теплых, жарких и засушливых (2007, 2010 годы) и холодных, с обилием осадков (2006, 2019 годы). Рассмотрены основные этапы технологии производства лука шалота при вегетативном и семенном способах размножения: выбор оптимального типа почвы, предшественника, подготовка почвы, сроки, схемы, нормы посева и посадки, орошение, защита от вредителей, болезней и сорняков, уборка, хранение, сорта шалота, внесенные Государственный реестр селекционных достижений и рекомендованные для выращивания в северных условиях. На Северо-Востоке Европейской части страны выборок шалота получают в трехлетней культуре по схеме: отбор и охлаждение маточников; весенняя посадка маточников, получение семян; получение севка из семян; получение лука выборка из севка. Для выращивания в Северо-Восточной части Приволжского федерального округа рекомендованы к выращиванию сорта лука шалота Зубаревский и Братский. In the North-Eastern part of the Volga Federal District, vegetatively propagated forms of onions are traditionally grown. The period of active vegetation of plants is 106–176 days, and the sum of temperatures above 10 °C is 1600–2400, which limits the seed propagation of onion crops. Recently, the demand of commodity producers for shallot planting material has been growing. Its cultivation is more labor-intensive than ordinary onions and requires certain skills in the work. According to its own nutritional indicators, it will always have a demand from the consumer. The aim of the work is to study the vegetative and seed methods of propagation of shallots in the conditions of the Kirov region. The article summarizes the results of studies of the Northern group of the shallots over the years 2001–2020 conducted by the laboratory of the Northern ARRIVG – branch of FSBSI FSVC in the Kirov region. The experiments were laid on sod-podzolic, well-cultivated soil, in vegetable crop rotations. Weather conditions were varied: from typical for the zone-according to most years of research, to abnormally warm, hot and dry (2007, 2010) and cold, with an abundance of precipitation (2006, 2019). The main stages of shallot production technology for vegetative and seed propagation methods are considered: selection of the optimal soil type, precursor, soil preparation, timing, schemes, sowing and planting rates, irrigation, protection from pests, diseases and weeds, harvesting, storage, shallot varieties included in the State Register of Breeding Achievements and recommended for cultivation in northern conditions. In the North-East of the European part of the country, shallot samples are obtained in a three-year culture according to the scheme: selection and cooling of queen bees; spring planting of queen bees, obtaining seeds; getting a seed crop; Getting an onion sample from the seed crop. For cultivation in the North-Eastern part of the Volga Federal District, the varieties of shallots Zubarevsky and Bratsky are recommended for cultivation.

<p>In the North-Eastern part of Ukraine the forest communities occupy considerable area and have great ecological and economic value. In natural forests herbs and subshrubs maintain the canopy cover through the recovery mechanism when the undergrowth of woody plants by height constitutes a part of the herbaceous and subshrub layer. Cenoflora within the lower layers of mixed coniferous-broad leaved forests of the southern part of the Eurasian forest zone is a fairly complete structural unit, especially in the central parts of the moisture and soil fertility gradients. Syntaxonomic adaptability of the lower layer plants of the forest communities in the North-East of Ukraine is established, and their ecological and biological diversity is determined as a result of the researches conducted. A group of species of forest herbs and subshrubs by the ecological status takes an intermediate position because of their habitat versatility. The species of this group are characterized by the vegetative propagation along with the effective seed reproduction. The habitat versatility and combination of the two types of reproduction are the main reasons for a wide representation of the species of this group in different syntaxons. A high floristic biodiversity of the forest communities of the North-Eastern part of Ukraine and their flora heterogeneity are determined based on the comparative floristic analysis. The floristic difference between the two major classes of vegetation in this region is shown, and it is found that Querco-Fagetea class is characterized by a high nutrient status and good warming-up under slightly reduced soil moisture, whereas the main feature of Vaccinio-Piceetea class is low soil fertility.</p>

Based on the lithofacies and structural analysis we consider a new variant of the structuralfacies zonation of the Bazhenov horizon (Tithonian — lower Berriasian) in the north-eastern part of West Siberia. The low content of terrigenous sedimentary material in high-carbon facies the bazhenov formation, due to its capture of relatively deep Pur-Tazovsky paleobasins, which formed the cone of the Yenisei-Khatanga sea strait. Pur-Tazovsky basin filled with the yanovstanskaya formation, he adjoined from the north-east to extensive relatively shallow Obsky paleobasin — the accumulation of black shale bazhenov formation.


The opinion that the continents of Asia and America are separated by the sea, seems first to have been inferred in 1736 by Professor Muller, and to have been founded upon some papers found at that time in Siberia, relating to the celebrated voyage of Deschneer, who in 1648 first discovered the sea east of Kamtschatka. The question, however, seems to have been undecided at the period of Behring’s voyage, as we learn from his instructions given by Peter the Great; and the Asiatic side only of Behring’s Strait was discovered by that navigator: for the coast of Asia being there found to take a western direction, it had the effect of giving an impression of the total separation of Asia and America. After noticing several other attempts to determine the north-eastern limits of Asia previous to the arrival of Captain Cook in the sea of Kamtschatka, Captain Burney proceeds to the observations of that navigator. The first extraordinary circumstance was a sudden disappearance of the tides in Behring’s Strait. Thence Captain Cook coasted the land of America to the north and north-east till stopped, in 70° 40' north latitude, by a floating body of ice. He then stood westward from the coast of Asia, keeping in as high a latitude as the ice would permit. The deepest soundings in this sea did not exceed 30 fathoms in latitude 68° 45', mid-way between the coasts of Asia and America. The soundings decreased to the northward, and did not increase in running from the coast of America westward, as is usual in running from land. These, and other peculiarities, gave so much the character of a mediterranean sea, that some on board, says the author, were of opinion that we were inclosed by land to the north, and that Asia and America were there united.
