The role of Greek culture representation in socio-economic development of the southern regions of Russia

This article researches how the Greek lingvoculture represented in onomasticon of the South of Russia. The South Russian anthroponyms, toponyms and pragmatonyms are considered in this article and how they verbalize the most important values and ideological views. It is proved in the article that the key concepts of the Greek lingvoculture such as: “Peace”, “Faith”, “Love”, “Heroism”, “Knowledge”, “Alphabet”, “Power”, “Charismatic person” and “Craft” are highly concentrated in the onomastic lexis of the researched region. The mentioned above concepts due to their specific pragmatic orientation are represented at different extend.peer-reviewe

Изменение стока снегового половодья на южном макросклоне Русской равнины в период 1930–2014 гг

In recent decades, in the southern macro-slope (catchment) of Te Russian Plain, mainly within the basins of the Volga and the Don rivers, the spring flood flow decreased due to both anthropogenic and climatic factors. Of anthropogenic factors, the creation of reservoirs played a signifcant role in changing the water regime of the Volga and the Don. Another important factor, affecting the river runoff, is agricultural activities on flat interfluves and slopes. Compared with the conventional-natural period (for the Volga from 1879, and for the Don from 1876 to 1929) to the date (for the period 1930–2014), the flood flow of the Volga has been decreased by more than 4300 km3, and the Don – by almost 900 km3. Te contribution of anthropogenic factors to this decrease in the Volga basin exceeded 70%, and for the Don it was equal to 45%, while the climatic ones contributed 30 and 55%, respectively. During the period of instrumental observations on the rivers of the region, long-lasting phases of high/low water content with duration from 15–20 to 90 years or longer, caused by the climatic changes, were determined. Tese are a characteristic feature of long-term changes in flood flow (and in a runoff of other seasons) on both medium and large rivers of the southern macro-slope of the Russian Plain. Te period since early 2000s was a start of the decreased flood flow everywhere, i.e. on medium and large rivers. It is most clearly (by tens of percent) manifested in the decrease of the spring surface flow due to the following factors: more frequent thaws, reduction of the depth of soil freezing, increase of infltration, especially in the forest-steppe and steppe zones. Increase in flow of the infltration origin does only partially compensate the decrease of the flow in rivers.Рассматриваются сток снегового половодья в пределах бассейнов Волги и Дона и его изменения под влиянием антропогенных и климатических факторов. Изложены методы исследования изменений речного стока, оценены его изменения за последние десятилетия. Общая тенденция – уменьшение стока половодья, что связано с гидротехническим воздействием и климатическими факторами

Панникулит Крисчена–Вебера у молодой пациентки с миастенией (описание клинического случая)

Christian–Weber disease refers to the group of panniculitis, which present an inflammation of the subcutaneous adipose tissue with the involvement of neutrophils, white blood cells and histiocytics, which leads to fibrosis in adipose tissue and sometimes to granulomatous changes. Clinically this pathology manifests from the formation of nodes in the subcutaneous adipose tissue, which appear suddenly, sporadically in some areas or multiple, sometimes forming large aggregations (plaques) or strands, shaped like a rosary. Consistency of nodes initially soft, then compacted, can form adhesions with the skin, the skin over them is not changed initially, followed by a color change from bright pink to brown-purple. Ends the process of atrophy of the affected area, sometimes with a depression in the center. Localization sites in the body are different; they are placed often on the buttocks, arms and legs. The duration of the process of the skin varies from a few days to a few months, after involution of old nodes may appear new ones, it are the cause of increasing the duration of the disease, having a relapsing course. It can be rather difficult to do differential diagnosis, which requires a great deal of experience of experts and a team approach to the study and treatment of this pathology. To confirm the diagnosis requires a biopsy of the skin. Prognosis depends on the nature of the disease and timely diagnosis.Болезнь Крисчена–Вебера относится к группе панникулитов, которые представляют собой воспаление подкожно-жировой клетчатки с вовлечением нейтрофилов, лейкоцитов и гистиоцитов, приводящее к фиброзу и иногда к гранулематозным изменениям. Клинически данная патология проявляется формированием узлов в подкожно-жировой клетчатке, которые возникают внезапно, единично или множественно, иногда образуя крупные скопления (бляшки) или тяжи, по форме напоминающие четки. Консистенция узлов вначале мягкая, затем они уплотняются, могут образовываться спайки с кожей, цвет кожных покровов над ними первоначально не изменен, но в последствии меняется от ярко-розового до коричнево-багрового. Заканчивается данный процесс атрофией пораженного участка, нередко с вдавлением в центре. Локализация узлов на теле различна, чаще они располагаются на ягодицах, руках и ногах. Длительность кожного процесса варьируется от нескольких дней до нескольких месяцев, при инволюции старых узлов могут появляться новые, что служит причиной увеличения продолжительности самого заболевания, имеющего рецидивирующее течение. Достаточно сложной может быть дифференциальная диагностика, требующая большого опыта специалистов и коллективного подхода к изучению и лечению данной патологии. Для подтверждения диагноза необходима биопсия кожи. Прогноз зависит от характера течения заболевания и своевременно установленного диагноза

Approaches in biotechnological applications of natural polymers

Natural polymers, such as gums and mucilage, are biocompatible, cheap, easily available and non-toxic materials of native origin. These polymers are increasingly preferred over synthetic materials for industrial applications due to their intrinsic properties, as well as they are considered alternative sources of raw materials since they present characteristics of sustainability, biodegradability and biosafety. As definition, gums and mucilages are polysaccharides or complex carbohydrates consisting of one or more monosaccharides or their derivatives linked in bewildering variety of linkages and structures. Natural gums are considered polysaccharides naturally occurring in varieties of plant seeds and exudates, tree or shrub exudates, seaweed extracts, fungi, bacteria, and animal sources. Water-soluble gums, also known as hydrocolloids, are considered exudates and are pathological products; therefore, they do not form a part of cell wall. On the other hand, mucilages are part of cell and physiological products. It is important to highlight that gums represent the largest amounts of polymer materials derived from plants. Gums have enormously large and broad applications in both food and non-food industries, being commonly used as thickening, binding, emulsifying, suspending, stabilizing agents and matrices for drug release in pharmaceutical and cosmetic industries. In the food industry, their gelling properties and the ability to mold edible films and coatings are extensively studied. The use of gums depends on the intrinsic properties that they provide, often at costs below those of synthetic polymers. For upgrading the value of gums, they are being processed into various forms, including the most recent nanomaterials, for various biotechnological applications. Thus, the main natural polymers including galactomannans, cellulose, chitin, agar, carrageenan, alginate, cashew gum, pectin and starch, in addition to the current researches about them are reviewed in this article.. }To the Conselho Nacional de Desenvolvimento Cientfíico e Tecnológico (CNPq) for fellowships (LCBBC and MGCC) and the Coordenação de Aperfeiçoamento de Pessoal de Nvíel Superior (CAPES) (PBSA).

The ensemble scenarios projecting runoff changes in large Russian river basins in the 21st century

An approach is presented for carrying out a long-term projection of river runoff changes in large Russian river basins in the first three decades of the 21st century. These changes may be caused by climate warming and socio-economic factors. The approach utilizes a method for scenario estimation of runoff changes with a range of possible climate warming effects. This range is chosen by generalizing calculation results obtained by using an ensemble of global climate models for two contrasting scenarios (A2 and B1) of globally-averaged air temperature rises. The approach also utilizes a method for alternative scenario estimation for water consumption as related to socio-economic changes. The estimates show that the expected runoff changes in the first third of this century due to climate warming scenarios can compensate the runoff decrease caused by the realization of some of the scenarios for socio-economic changes in the Volga River basin. The same compensation does not occur in the Don River basin, where negative effects are expected for the regional ecology

INTEGRATED PROJECTION FOR RUNOFF CHANGES IN LARGE RUSSIAN RIVER BASINS IN THE XXI CENTURY

The paper discusses an approach to a long-term forecast of river runoff changes for Russian large river basins in the first third of the XXI century caused by climate warming and social-economic changes. The approach considers runoff changes under a range of possible climate warming effects. This range is chosen by generalizing the calculation results obtained by using an ensemble of global climate models within CMIP 3 and CMIP 5 experiments for twocontrasting scenarios (A2/RCP 8.5 and B1/RCP 2.6) of globally averaged air temperature rises. The approach also utilizes a method for alternative scenario for water consumption related to socio-economic changes. The obtained scenario estimates show that expected changes in the Volga and Don annual river runoff and its intra-annual distribution in the first third of this century can be relatively small, while changes in water use characteristics may be extremely negative in some scenarios, especially in the Don River basin
