The paper is devoted to the outstanding soviet geographer and soil scientist, Doctor of Geographical Sciences (1964), Professor (1968) Vladimir Fridland (1919–1983). A prominent place in his research works was taken by geospatial comparative-geographic studies. V. Fridland took part in many research projects in various parts of the world, including his motherland. From the actualistic and evaluative positions, the paper considers the important (at present) results from the seminal works of V. Fridland, which he had obtained using a wide range of methodological tools and research techniques, including comparative-geographical approach. V. Fridland also made an important contribution to the formation and development of natural geography. He enriched theoretical, methodological and applied aspects not only of soil science, but of geography in general. In his work of 1956, the scientist convincingly, in a concise comparative form and causal relationship, highlighted the natural conditions of the USSR and outlined their foreign analogues. In his influential work of 1964, V. Fridland had investigated the weathering processes, types of weathering, genesis and geography of soils in Northern Vietnam. In the 1970s, the pioneering scientist created a new research area – the doctrine of the structure of soil cover. Through field research in many regions of the Earth, the scientist has used and improved the approaches and methods of many natural sciences, including comparative one. V. Fridland successfully and productively used in scientific research almost the entire range of comparative-geographical methods. V. Fridland was the first one in the soviet geography to identify comparative method as an approach.

Microorganisms moderate local chemical conditions and alter forms of metals indirectly or directly to meet their cellular, species, and consortia needs. The diversity of microorganisms and the complexity of biogeochemical systems ensures that bacterially mediated processes yield a wide range of products, which await discovery by material scientists. Few types of materials produced by environmental bacteria have been analyzed by modern chemical and material science methods. Research on actinide biomaterials has focused on the biomineralization of a few chemical forms of uranium, neptunium, and plutonium. The materials produced are molecular complexes, microcrystalline minerals (most commonly oxides and phosphates) within cells and biofilms, and mineral adsorbates. The actinide biomaterials that emerge from this new research area will impact nuclear waste isolation and increase our understanding of environmental and geological metal cycles and may yield new bioremediation methods and industrially useful materials.

The research in thin film solar cells has been dominated by light absorber materials based on CdTe and Cu(In,Ga)Se2(CIGS) in the last several decades. The concerns of environment impact of cadmium and the limited availability of indium in those materials have driven the research towards developing new substitute light absorbers made from earth abundant, environment benign materials. Cu2ZnSnS4(CZTS) semiconductor material has emerged as one of the most promising candidates for this aim and has attracted considerable interest recently. Significant progress in this relatively new research area has been achieved in the last three years. Over 130 papers on CZTS have been published since 2007, and the majority of them are on the preparation of CZTS thin films by different methods. This paper, will review the wide range of techniques that have been used to deposit CZTS semiconductor thin films. The performance of the thin film solar cells using the CZTS material will also be discussed.

As environmental history migrates to the Middle East there is natural excitement about new research methods such as molecular biology and soil science. But the Braudelian project of describing “man in his intimate relationship to the earth which bears and feeds him” may be complicated by echoes of the region's literary past.

The most common known about biological and ecological function of soils is their fertility, or in a broader sense – the biological productivity of soil. Despite the very small thickness of soil cover on the Earth, which is just a thin layer on the surface, this layer is the most biologically productive part of the biosphere. It is proved that the most important impact soils provided on human health, especially because of anthropogenic pollution of soils. Particularly one of the most discussed is the problem of anthropogenic pollution of soils in urban areas near major highways, in areas of mining, including oil, gas, non-ferrous metals, building materials, as well as soil pollution by radioactive elements and pesticides. Key words: soils, soil science, soil degradation, soil pathology, healthy of soil.

Background: Software is now ubiquitous within research. In addition to the general challenges common to all software development projects, research software must also represent, manipulate, and provide data for complex theoretical constructs. Ensuring this process of theory-software translation is robust is essential to maintaining the integrity of the science resulting from it, and yet there has been little formal recognition or exploration of the challenges associated with it. Methods: We thematically analyse the outputs of the discussion sessions at the Theory-Software Translation Workshop 2019, where academic researchers and research software engineers from a variety of domains, and with particular expertise in high performance computing, explored the process of translating between scientific theory and software. Results: We identify a wide range of challenges to implementing scientific theory in research software and using the resulting data and models for the advancement of knowledge. We categorise these within the emergent themes of design, infrastructure, and culture, and map them to associated research questions. Conclusions: Systematically investigating how software is constructed and its outputs used within science has the potential to improve the robustness of research software and accelerate progress in its development. We propose that this issue be examined within a new research area of theory-software translation, which would aim to significantly advance both knowledge and scientific practice.

The textbook is devoted to the soil resources of Ukraine, as an indispensable natural and economic potential for use in agricultural production to meet the needs of society with food products. Their great diversity is shown due to the component composition regarding the zonation of the ecological and genetic status of soils. Presence for the soil resources of functionally systematic interrelation between ecological conditions of the formation of agronomic properties and their productive capacity have been proved. Due to a large amount of information, the textbook is conventionally divided into two parts. The second part of the textbook presents the genetic ecological-substantive classification of soils of Ukraine as a parametric system of their differentiation in the context of the hierarchy of taxonomic units on the basis of adequacy between quantitative indicators of their properties and conditions of formation. Therefore, soil nomenclature is a resource indicator. On the basis of soil ecological zoning, 6 successive levels of territorial differentiation of soil cover were established according to the principle of soil bodies adequacy to environmental conditions. Each selected structural unit of the pedosphere (zone, subzone, facies, province, pedopotsella, and pedorotope) is characterized by specific features of the properties and parameters of natural factors of their formation. Therefore, in the designated territories, they in the aggregate cause the formation of different agricultural potential resource parameters. Therefore, soil-ecological zoning is the basic basis for the differentiation of land resources by natural and efficient soil fertility. Zonality as a factor in soil geography by ecological-genetic status. Therefore, the characteristics of soils in the textbook are given within the soil-ecological zones, their morphological and quantitative diagnostics and agro-soil potential of the basic agricultural crops. Specialization in agriculture is a strategic measure of the efficient use of soil resources. Zones of specialization of agriculture of Ukraine in accordance with soil and ecological conditions. Land resource monitoring and large-scale soil cover research are strategic measures for its effective balanced use. The textbook “Ukrainian Agronomic Soil Science” presents basic information about soil resources of Ukraine in the aspect of agronomic orientation regarding their zonally determined ecological-genetic status of soils, their properties, productive capacity, protection, and increase of fertility. It is recommended for the preparation of bachelors in agronomic higher education institutions of II–IV levels of accreditation in the field of “Agronomy”, as well as for biological, geographical and other higher educational establishments, graduate students and a wide range of specialists related to the land cadastre of Ukraine, fertility assessment rational use of soils.

The brain is a complex, multiscale dynamical system composed of many interacting regions. Knowledge of the spatiotemporal organization of these interactions is critical for establishing a solid understanding of the brain’s functional architecture and the relationship between neural dynamics and cognition in health and disease. The possibility of studying these dynamics through careful analysis of neuroimaging data has catalyzed substantial interest in methods that estimate time-resolved fluctuations in functional connectivity (often referred to as “dynamic” or time-varying functional connectivity; TVFC). At the same time, debates have emerged regarding the application of TVFC analyses to resting fMRI data, and about the statistical validity, physiological origins, and cognitive and behavioral relevance of resting TVFC. These and other unresolved issues complicate interpretation of resting TVFC findings and limit the insights that can be gained from this promising new research area. This article brings together scientists with a variety of perspectives on resting TVFC to review the current literature in light of these issues. We introduce core concepts, define key terms, summarize controversies and open questions, and present a forward-looking perspective on how resting TVFC analyses can be rigorously and productively applied to investigate a wide range of questions in cognitive and systems neuroscience.

Background: Solubility and dissolution profile are the major factors which directly affect the biological activity of a drug and these factors are governed by the physicochemical properties of the drug. Crystal engineering is a newer and promising approach to improve physicochemical characteristics of a drug without any change in its pharmacological action through a selection of a wide range of easily available crystal formers. Objective: The goal of this review is to summarize the importance of crystal engineering in improving the physicochemical properties of a drug, methods of design, development, and applications of cocrystals along with future trends in research of pharmaceutical co-crystals. Co-crystallization can also be carried out for the molecules which lack ionizable functional groups, unlike salts which require ionizable groups. Conclusion: Co-crystals is an interesting and promising research area amongst pharmaceutical scientists to fine-tune the physicochemical properties of drug materials. Co-crystallization can be a tool to increase the lifecycle of an older drug molecule. Crystal engineering carries the potential of being an advantageous technique than any other approach used in the pharmaceutical industry. Crystal engineering offers a plethora of biopharmaceutical and physicochemical enhancements to a drug molecule without the need of any pharmacological change in the drug.
