Correlation of administrative definitions of refugees and internally displaced persons: geopolitical concretion in ukraine and its compliance with international standards

The purpose of this study is to investigate the correlation of administrative definitions of refugees and internally displaced persons, as well as compliance of these definitions with international standards. The methodological framework of the study included analytical, legal, and statistical methods of analysis. The study employed general scientific and special methods of cognition. The paper investigates the main provisions of the legislative framework at the international and national levels. The applied methods allowed obtaining reliable and reasonable conclusions and results. Therefore, it is necessary to legislatively regulate the situation of persons who have been in Ukraine for a long time in violation of the law. This paper presents the criteria for the correlation between the terms “refugee” and “internally displaced person”. The practical value of this study lies in the fact that the investigation of the correlation of administrative definitions of refugees and internally displaced persons and their compliance with international standards is essential for practitioners and theorists in legal science

Infused polymers for cell sheet release

Tissue engineering using whole, intact cell sheets has shown promise in many cell-based therapies. However, current systems for the growth and release of these sheets can be expensive to purchase or difficult to fabricate, hindering their widespread use. Here, we describe a new approach to cell sheet release surfaces based on silicone oil-infused polydimethylsiloxane. By coating the surfaces with a layer of fibronectin (FN), we were able to grow mesenchymal stem cells to densities comparable to those of tissue culture polystyrene controls (TCPS). Simple introduction of oil underneath an edge of the sheet caused it to separate from the substrate. Characterization of sheets post-transfer showed that they retain their FN layer and morphology, remain highly viable, and are able to grow and proliferate normally after transfer. We expect that this method of cell sheet growth and detachment may be useful for low-cost, flexible, and customizable production of cellular layers for tissue engineering

Elliptic flow of muons from heavy-flavour hadron decays at forward rapidity in Pb-Pb collisions at root s(NN)=2.76TeV

The elliptic flow, v(2), of muons from heavy-flavour hadron decays at forward rapidity (2.5 <y <4) is measured in Pb-Pb collisions at root s(NN)= 2.76TeVwith the ALICE detector at the LHC. The scalar product, two- and four-particle Q cumulants and Lee-Yang zeros methods are used. The dependence of the v(2) of muons from heavy-flavour hadron decays on the collision centrality, in the range 0-40%, and on transverse momentum, p(T), is studied in the interval 3 <p(T)<10 GeV/c. A positive v(2) is observed with the scalar product and two-particle Q cumulants in semi-central collisions (10-20% and 20-40% centrality classes) for the p(T) interval from 3 to about 5GeV/c with a significance larger than 3 sigma, based on the combination of statistical and systematic uncertainties. The v(2) magnitude tends to decrease towards more central collisions and with increasing pT. It becomes compatible with zero in the interval 6 <p(T)<10 GeV/c. The results are compared to models describing the interaction of heavy quarks and open heavy-flavour hadrons with the high-density medium formed in high-energy heavy-ion collisions.

Stop and smell the grapes : altering cultivar-typical aromas in ‘Gewürztraminer’ (Vitis vinifera L.) berries via regulated deficit irrigation and crop load management

Grape growers use viticultural practices such as deficit irrigation and crop load management via cluster thinning to improve phenolics and aromas in red grapes and wines; however, the impact of these practices on grape terpenes – key aromatics for quality in wines – remains largely unknown. I performed two three-year studies to investigate the effect of deficit irrigation and crop load management strategies on the accumulation of terpenes in Gewürztraminer grapes grown in the Okanagan Valley (BC, Canada). Yield and grape sugars were reduced by deficit irrigation treatments; however, effects were minimal when the deficit was applied late in the season. Applying late deficit allowed to save ~30% of irrigation water compared to standard irrigation. Total free terpenes were not affected by deficit irrigation treatments, but the concentration of key terpenes for the aroma of Gewürztraminer wines, such as geraniol and citronellol, was significantly increased in grapes exposed to water deficit late in the season. This irrigation treatment did not affect the expression of terpene genes, suggesting that the increased concentration of specific terpenes was not regulated at the transcriptional level. Reducing the crop load stimulated sugar accumulation, particularly if this reduction was applied early in the season. Reducing the crop load early during the season also increased the terpene levels before the commercial harvest (20-21 oBrix), but had no effects at harvest, suggesting a faster accumulation of terpenes during ripening. The peak of expression of several terpene synthases occurred before the commercial harvest. Expression of two terpene synthases was increased in grapes of grapevines subjected to crop load reduction early in the season. My studies indicate that it is possible to modulate terpenes in vineyards by managing irrigation and crop load. However, I observed that the seasons had a stronger effect on terpenes than the treatments investigated.Land and Food Systems, Faculty ofGraduat

Green energy projects in households and its financial support in Ukraine

The paper deals with the solar energy promotion in households in Ukraine. Despite the positive dynamics of solar power plants construction, today the share of electricity, generated on their basis, in the country’s electricity mix remains insignificant. The main reason for this is the need for essential start-up investments. Since the economic efficiency of investment projects depends on installed capacity of plants, the structure and cost of the project financing sources; the paper focuses on estimation of financial sustainability of solar photovoltaic power plants construction under the credit programme ‘Eco-Energy’. The obtained results show the high profitability of own and credit resources’ investment in the considered projects that varies from 78.91% for the 10 kW solar power plants to 128.04% for the 30 kW ones. On this basis, policy recommendations for improving financing and other economic mechanisms to enhance renewable energy development in Ukrainian households have been developed

The specified non-conformity of the legislation of Ukraine should be eliminated in two parallel ways. The specified non-conformity of the legislation of Ukraine should be eliminated in two parallel ways. On the one hand, any restrictions on the circle of persons to whom it applies should be excluded from the definition of IDPs in Article 1 of the Law of Ukraine “On Ensuring the Rights and Freedoms of Internally Displaced Persons”, primarily regarding the presence of stateless persons on the territory of Ukraine on legal grounds and the right to permanent residence in Ukraine. On the other hand, the corresponding law approves the procedure for determining a person as stateless, or apatride. This paper presents the criteria for the correlation between the terms “refugee” and “internally displaced person”. The practical value of this study lies in the fact that the investigation of the correlation of administrative definitions of refugees and internally displaced persons and their compliance with international standards is essential for practitioners and theorists in legal science

Bacterial Interactions with Immobilized Liquid Layers

Bacterial interactions with surfaces are at the heart of many infection-related problems in healthcare. In this work, the interactions of clinically-relevant bacteria with immobilized liquid (IL) layers on oil-infused polymers are investigated. Although oil-infused polymers reduce bacterial adhesion in all cases, complex interactions of the bacteria and liquid layer under orbital flow conditions are uncovered. The number of adherent Escherichia coli cells over multiple removal cycles increases in flow compared to static growth conditions, likely due to a disruption of the liquid layer continuity. Surprisingly, however, biofilm formation appears to remain low regardless of growth conditions. No incorporation of the bacteria into the layer is observed. Bacterial type is also found to affect the number of adherent cells, with more E. coli remaining attached under dynamic orbital flow than Staphylococcus aureus, Pseudomonas aeruginosa under identical conditions. Tests with mutant E. coli lacking flagella confirm that flagella play an important role in adhesion to these surfaces. The results presented here shed new light on the interaction of bacteria with IL layers, highlighting the fundamental differences between oil-infused and traditional solid interfaces, as well as providing important information for their eventual translation into materials that reduce bacterial adhesion in medical applications.Chemistry and Chemical Biolog
