Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has emerged as a novel coronavirus in late 2019, since then it is infecting people and spreading efficiently among humans worldwide, causing the infectious disease named coronavirus disease 2019 (COVID-19). Some patients infected with SARS-CoV-2 develop severe inflammatory‐induced lung injury as a result of a cytokine storm syndrome (CSS),...

The paper presents the results of research on the methylene blue (MB) degradation with sodium persulfate (PDS) activated with visible light (Vis) in the presence of glucose and sucrose. The following test were examined: absence and presence of sugars in concentrations of 50–300 mM, presence and absence of Vis radiation, pH of the model solution (6.0–12.0), identification of free radicals, kinetics...

Photocatalytic decomposition of chlorfenvinphos (CFVP) in the presence of titanium dioxide (TiO2) modified with organic acids: pyruvic (PA) and succinic (SA) under the visible light radiation has been studied. The following tests were examined: dose of photocatalysts, adsorption time, pH of the model solution, deactivation of catalysts, the role of oxygen, identification of free radicals for the CFVP...

The solubility of Sulfanilamide in binary mixtures comprising water and five organic solvents was studied at different temperatures using a spectrophotometric method. Additionally, the differential scanning calorimetry (DSC) measurements were performed to characterize the non-dissolved portion of Sulfanilamide obtained after shake-flask experiments. The Buchowski-Ksiazczak solubility model was applied...

Finding the best matching job offers for a candidate profile or, the best candidates profiles for a particular job offer, respectively constitutes the most common and most relevant type of queries in the Human Resources (HR) sector. This technically requires to investigate top-k queries on top of knowledge bases and relational databases. We propose in this paper a top-k query algorithm on relational...

Dicarboxylic acids (DiAs) are probably one of the most popular cocrystals formers. Due to the high hydrophilicity and non-toxicity, they are promising solubilizes of active pharmaceutical ingredients (APIs). Although DiAs appear to be highly capable of forming multicomponent crystals with various compounds, some systems reported in the literature are physical mixtures the solid state without forming...

Purpose Study on curcumin dissolved in natural deep eutectic solvents (NADES) was aimed at exploiting their beneficial properties as drug carriers. Methods The concentration of dissolved curcumin in NADES was measured. Simulated gastrointestinal fluids were used to determine the concentration of curcumin and quantum chemistry computations were performed for clarifying the origin of curcumin solubility...

A comprehensive experimental and theoretical screening was performed for identification of curcumin solubilizers. Experimental data led to formulation of a non-linear QSPR model correlating molecular descriptors with measured solubilities. The majority of synthesized binary systems exhibited a moderate enhancement of curcumin solubility, which was found to be the highest in the case of curcumin cocrystallized...

A new method of Hansen solubility parameters (HSPs) prediction was developed by combining the multivariate adaptive regression splines (MARSplines) methodology with a simple multivariable regression involving 1D and 2D PaDEL molecular descriptors. In order to adopt the MARSplines approach to QSPR/QSAR problems, several optimization procedures were proposed and tested. The effectiveness of the obtained...

Recent observations of thick carpets of mobile salt slurries on the Red Sea floor (Salt Flows) and huge accumulations of salts in the sub-surface (‘Salt Walls’ and ‘Salt Ridges’), associated with topographical lows (Deeps), suggest that the Red Sea currently produces new volumes of brines and solid salts underground. The salt producing zone is focused around the central rifting axis and represents...

Objective: The aim of this study was to explore the possibility of using natural deep eutectic solvents (NADES) as solvation media for enhancement of solubility of sulfonamides, as well as gaining some thermodynamic characteristics of the analyzed systems. Significance: Low solubility of many active pharmaceutical ingredients is a well-recognized difficulty in pharmaceutical industry, hence the need...

W artykule przeanalizowano dostępność oraz jakość przestrzeni trzech krakowskich osiedli: Azory, Dębniki, Nowy Bieżanów w kontekście użytkowania ich przez osoby starsze. Każdy z badanych obszarów charakteryzuje się odmienną strukturą funkcjonalno-przestrzenną oraz lokalnym środowiskiem architektonicznym. Celem analiz jest zwrócenie uwagi na potrzeby najstarszych mieszkańców miast, których udział w...

W roku 2017 wykonano metodą spływu, inwentaryzację ptaków związanych z korytem rzeki Pilicy. Liczeniami objęto 140 km odcinek rzeki od zapory w Smardzewicach do ujścia do Wisły. Przedmiotem inwentaryzacji było 31 gatunków, których liczebność oceniano podobną metodą w latach 1974, 1987-1989, 2003-2004 . Na przestrzeni porównywanych lat odnotowano istotne z punktu widzenia trwałości siedlisk lęgowych...

Functional connectivity modeling is increasingly used to predict the best spatial location for over- or underpasses, to mitigate road barrier effects and wildlife roadkills. This tool requires estimation of resistance surfaces, ideally modeled with movement data, which are costly to obtain. An alternative is to use occurrence data within species distribution models to infer movement resistance, although...

This study aims to examine the changes of mangrove forest associations and possible reasons for changes via the Can Gio biosphere reserve, Viet Nam case study by using SPOT imagery, objectbased image analysis, and the Support Vector Machine classifier. The highest overall accuracy of this combination was 81.6%, confirming the applicability of using remote sensing on evaluating the development of mangrove...
