В статье изложены результаты многолетних исследований генезиса, морфологии, особенностей функционирования, современного состояния и динамики малых эрозионных форм рельефа в условиях котловин гор Южной Сибири на примере Южно-Минусинской котловины. Овражные формы представлены здесь локально. Доминируют береговые промоины и овраги, секущие крутые борта долин рек Абакан, Енисей и их притоков. Густота расчленения и плотность современных овражных форм рельефа возрастает на сельскохозяйственных землях (пашни и пастбища) и в пределах селитебных ландшафтов. Размеры малых эрозионных форм рельефа отличаются большим диапазоном. Так, протяженность коротких промоин составляет первые десятки метров, длинных логов — 3–5 км. Глубина вреза изменяется от 1,5–3 м до 10–20 м, ширина между бровками достигает 40–60 м. В настоящее время, несмотря на период увеличения увлажненности территории, после достаточно длительного засушливого периода овражные формы активно задерновываются. Этому способствует рост температуры и выпадение осадков слабой интенсивности. В результате происходит зарастание нарушенных земель ильмом мелколистным, наблюдается превращение степных ландшафтов в парковые. The article discusses the results of a multiannual research of the genesis, morphology, modern state and dynamics of minor landforms that can be found in the mountains of Southern Siberia in the Southern-Minusinsk Hollow. The majority of ravine landforms found in the area are bank gullies infesting the steep banks of the Abakan River, the Yenisei River and their tributaries. The density of ravine dismemberment increases in agricultural areas (arable lands and pastures) and in residential areas. The size of ravine landforms varies over a wide range. The length of short gullies does not exceed a few dozen meters. The length of long logs can reach 3–5 kilometres. The depth of incision varies from 1.5–3 metres to 10–20 metres. The distance between the brows of a ravine can reach 40–60 meters. Nowadays, despite a period of higher humidity, prolonged dry periods and high temperatures make ravines peaty. As a result, the areas overgrow with small-leaved elm and steppe landscapes are gradually transformed into parks.

Ethnocultural Identity

The Yenisei river occupies a significant place both in the sphere of regional identity and in paintings and graphic works of Krasnoyarsk artists, since it forms the image of Krasnoyarsk and is a connecting link of the Yenisei Siberia. The article analyses paintings and graphic works of Krasnoyarsk artists to identify the features of the image of the Yenisei in regional art. The study is based on the theoretical principles of the modern theory of visual arts and on the analysis of the selected paintings and graphic works of Krasnoyarsk artists of the 20th and 21st centuries from the collection of the Krasnoyarsk Art Museum named after V.I. Surikov. A wide range of sources, including studies of ethnocultural identity, the specific features of artistic culture and the characteristics of Krasnoyarsk landscapes is considered. In the process of comparing the analysis results, it has been revealed that for Krasnoyarsk artists the Yenisei is not only the embodiment of endless natural forces, but also a connecting and harmonising link between the human world and the natural world, at the same time representing a special identity of Siberians (Amosova, et al., 2019)

<p>The Soil Science Institute of Thessaloniki produces new digitized Soil Maps that provide a useful electronic database for the spatial representation of the soil variation within a region, based on in situ soil sampling, laboratory analyses, GIS techniques and plant nutrition mathematical models, coupled with the local land cadastre. The novelty of these studies is that local agronomists have immediate access to a wide range of soil information by clicking on a field parcel shown in this digital interface and, therefore, can suggest an appropriate treatment (e.g. liming, manure incorporation, desalination, application of proper type and quantity of fertilizer) depending on the field conditions and cultivated crops. A specific case study is presented in the current work with regards to the construction of the digitized Soil Map of the regional unit of Kastoria. The potential of this map can easily be realized by the fact that the mapping of the physicochemical properties of the soils in this region provided delineation zones for differential fertilization management. An experiment was also conducted using remote sensing techniques for the enhancement of the fertilization advisory software database, which is a component of the digitized map, and the optimization of nitrogen management in agricultural areas.</p>

The Yenisei River

The distribution of dissolved chemical elements (major ions, nutrients, and trace elements) in the Yenisei River estuary and adjacent water area in 2009 and 2010 are presented. These results were compared to the data obtained during previous hydrochemical studies of this region. The transport of major cations (Na, K, Mg, Ca) and some trace elements (Rb, Cs, Sr, B, F, As, Mo, U) in the estuary follows conservative mixing. Alkalinity also belongs to conservative components, however this parameter exhibits substantial spatial heterogeneity caused by complex hydrological structure of the Yenisei Bay and adjoining part of the Kara Sea formed under the influence of several sources of desalination and salty waters inflow. Concentrations of Pmin, Si, and V in the desalinized waters of photic layer decrease seaward owing to uptake by phytoplankton. The losses of these elements reach 30–57, 30, and 9% of their supply by river runoff, respectively. The content of dissolved phosphates and vanadium in the intermediate and near-bottom layers of the Yenisei River estuary strongly increases with salinity due to regeneration of precipitated organic matter, whereas silica remineralization is much less pronounced. Barium is characterized by additional input of dissolved forms in the mixing zone in the quantity comparable to that carried out by river runoff. This may be caused by its desorption from river suspended matter due to ion exchange. The transport of dissolved Al and Mn in the estuarine zone is probably controlled by the coagulation and flocculation of organic and organomineral colloids, which is indicated by a decrease in the concentration of these elements at the beginning of the estuary (31 and 56%, respectively) followed by a stable concentration further seaward.

Ordered mesoporous silica materials are of interest for a wide range of applications. In many of these, elevated temperatures are used either in the preparation of the material or during its use. Therefore, an understanding of the effect of high temperature treatments on these materials is desirable. In this work, a detailed structural study is performed on silicas with three representative pore structures: a 2-D hexagonal pore arrangement (SBA-15), a continuous 3D cubic bimodal pore structure (KIT-6), and a 3D large cage pore structure (FDU-12). Each silica is studied as prepared and after treatment at a series of temperatures between 300 and 900°C. Pore structures are imaged using Transmission Electron Microscopy. This technique is used in conjunction with Small-Angle X-ray Diffraction, gas physisorption, and29Si solid state Nuclear Magnetic Resonance. Using these techniques, the pore size distributions, the unit cell dimensions of the mesoporous structures, and the relative occupancy of the distinct chemical environments of Si within them are cross correlated for the three silicas and their evolution with treatment temperature is elucidated. The physical and chemical properties before, during, and after collapse of these structures at high temperatures are described as are the differences in behavior between the three silica structures.
