The article is devoted to the problems of the development of the Arctic as a territory of international cooperation, taking into account the national interests of individual states. The specificity of geopolitical, social, economic, and climatic conditions determines the need to develop conceptual foundations of legal support for the implementation of environmental engineering processes at the development of the Arctic and research on climatic changes of the region. The article analyzes the main strategic and legal documents regulating the implementation activities in relation to the technical and technological support in the question of the development of the Arctic territories and the preservation of climatic stability. The options for creating an adequate system of convergence of national and international legal regulation in the field of determining anthropogenic pollutants and fixing key indicators of the state of the Arctic environment are detailized and characterized. The scientific substantiation of the causes and consequences of climate change in the Arctic ecological systems is given. The advantages of scientific research with the use of modern engineering and digitalization methods, as well as the usage of information and communication technologies for the prompt exchange of environmentally significant information, are revealed. It is noted that thе most topical issues, the national strategies for the development of the Arctic zones of the Russian Federation, Denmark, Norway, and Canada are of a similar nature. They have common approaches to the preservation of vulnerable Arctic ecological systems and the conceptual foundations of legal support for engineering in Arctic scientific research in the field of climate change and conservation.

The old (Upper Pleistocene and modern soils inside of ancient settlement near v. Troyanove on Kyrovogradschyna (Ukraine) during complex archeological investigation with archeologist L.L. Zaliznyak. The paleopedological method with wide applying of geoarcheological approach was using for to set soil types, trends of development and changes of climate in time as result of comparing of ancient and modern soils. According to invitation of doctor of historic sincere archeologist prof. L.L. Zaliznyak authors studied Upper Paleolithic soils inside of ancient settlement near v. Troyanove on Kyrovogradschyna. The aim of studying were: to determined types of the buried soils; according possibility to reconstruct human habitation nature conditions of the last; to set trends of climatic changes in time. The publications which have attention to the trend of Holocene soils development; the profiles of ancient and inside of ancient v. Troyanove on Kyrovogradschyna. The aims studying were: to determined types of the buried soils; according possibility to reconstruct human habitation nature condition of the last; to set trends of climatic changes in time. The publications which have attention to the trend of Holocene soils development and profiles of ancient and modern soils were analyzed. The last were studied in the 3-th section, but only in the section 1 and 2 archeological artifacts were found out. In the section 1 siliceous material was laying lower of modern soil in Bug loess above vitachiv soil surface. In the section 2 modern chernozem had thickness 0,8-0,9 m and in lower part had erosion loud withBug loess where archeological material we concentrating in sediments. So, in the 1 section as well as in the 2-th section there were artifacts in the upper part of the Bug loess (about 24000 BP). Losses, that were keeping, according paleopedological (including micromorphological) data signs of formation in the cold or temperate-cold climate of steppe with spreading of rarely forest and bushes in the river valleys and gullies. May be there was the stage of sediments interraption between big loess and modern soil formation. In the section 3 background soil is represented by the Holocene chernozem about 0,9 m thick with clear Pk. Comparing modern and ancient soil (the last with siliceous material) allowed to conclude about grow warm conditions of climate for modern soil formation. In the modern time territory is disposing in the forest-steppe zone of temperate-warm climate, but in the Paleolyte conditions of temperate-cold or cold steppe climate were prevailed. More late investigations allowed to summary red data about nature conditions of habitant living in Kyrovogradschyna in the monography under redaction of L. L.

Voluntary intoxication can be used as a basis for the insanity defense in certain cases. I review the obscure concept of “settled insanity “ in California case law and note its 100–year evolution from a “permanent” state of mind, usually associated with chronic alcoholism, to a current test of temporary insanity wherein the mental disorder must be fixed, stable, of reasonable duration, and not solely dependent upon the ingestion or duration of the drug. I argue that this definition is tautological and arbitrary and propose a new definition of “settled insanity” based only upon a demonstrated predisposition to psychosis. This definition is consistent with current scientific research concerning psychosis-proneness in individuals who become paranoid and delusional through the use of psychostimulants, the class of drugs now most likely to contribute to a voluntary intoxication-insanity defense strategy.

Gay gray-brown soils are distributed mainly in the foothills of the Lesser Caucasus, on the Ganja-Gazakh plain and in the lower reaches of the Araz basin. They are formed by changing volcanic rocks in hot and dry climates. In the process of erosion and soil formation, pyrite, alunitized and other sulfur-containing rocks turn into gazh, on which gray-brown gazh soils are formed. As a result of human activity, i. e. deep plowing and irrigation, these lands are being converted. It turned out that the transformation of these soils is clearly felt in the thickness of the humus layer, its distribution along the profile, quantity and composition. The thickness of the humus layer increases from 40–45 cm to 100 cm. As a result of the transformation, the length of the humus profile is constantly decreasing. Changes in the composition of humus led to an increase in the content of humic acids. Although the coefficient in the uncultivated area decreased from 1.36 to 0.80, in the irrigated area it changed from 1.70 to 0.93.

Paleosols that formed primarily before the last glaciation cannot be adequately explained by a model of Holocene-like interglacial periods of about 10,000 yr in length which has been inferred from the marine 18O16O record. Geological and palynological evidence from terrestrial, midlatitude sites suggests that temperate conditions conducive to soil formation existed for periods greatly in excess of 10,000 yr during the middle and late Pleistocene. Available data on soils formed during this interval from Western Europe and midwestern United States are best explained by relatively long interglaciations or the development of composite soils over a number of temperate periods. Climatic contrasts between the interglaciations appear to have been overemphasized: widespread assumptions regarding greater warmth in interglaciations prior to the present one are generally unproven. In the absence of precise dating, progress in relating paleosols to fragmentary local records of Quaternary climatic changes will be achieved by detailed analytical techniques such as soil micromorphology.

Abstract. A Pliocene alluvial fan sequence of soils and sediments with 24 fossil soils in the northeastern part of the Granada Basin was investigated. The reddish brown to red soils and the (soil-)sediments substantiate a multiple alternation of sedimentation and (differently intensive) soil formation. Accumulation took place during dry and morphodynamic active periods without vegetation cover and soil formation during wet and morphodynamic stable periods with vegetation. Hence a high number of climatic changes has to he postulated to this - still not defined – part of the Pliocene.

Ni0.76Co0.24Ox xerogels were formed by the sol-gel method followed by heat-treatment in air. The structure and properties of these materials were characterized by using X-ray diffraction, TEM and N2 (77K) adsorption. Electrodes with the xerogels were activated by cyclic voltammetry (CV) and their capacitive performance was evaluated by galvanostatic technique in 7 mol/L KOH solutions. A maximum specific capacitance of 904 F/g was obtained by constant current discharge with a current density of 2.0 mA/cm2 for the Ni0.76Co0.24Ox xerogels heat-treated at 250°C. High performance obtained indicates that these materials are promising electrode materials for supercapacitors.
