The rate of increase in industrialization and daily human activities has resulted in a tremendous increase in the amounts of waste and wastewater containing organic and inorganic pollutants discharged to the environment. Coagulation-flocculation technology has been widely employed in water/wastewater treatment as a convenient and reliable technique for removing colloids, particles, and cell deb...

our study performed upon an extended series of 28 compounds of 1,2,4-triazole derivativesthat demonstrate substantial in vitro antimicrobial activities by serial plate dilution method,using quantitative structure-activity relationship (qsar) methods that imply analysis ofcorrelations and multiple linear regression (mlr); a significant collection of moleculardescriptors was used e.g., edge adjac...

one-pot multicomponent reaction between isatin, barbituric acid, and 6-amino-1,3-dimethyl uracil was investigated in the presence of sulfonic acid functionalized nanoporous silica (sba-pr-so3h) and resulted in the formation of spirooxindole dipyrimidines. spirooxindole unit is found in many natural products and biologically active molecules and 1,4-dihydropyridines are an important class of com...

Stone monuments (statues, fountains, tombs, memorials, buildings, etc.) are apparently indestructible artefacts that were built to last. Depending on the chemical composition and structure, stones may be friendly or hostile to colonization by eukaryotic and/or prokaryotic communities. Among various lithotypes, porous rocks (limestone, sandstone) have highest bioreceptivity. Abiotic factors have...

During the annual cycle, migratory waders may face strikingly different feeding conditions as they move between breeding areas and wintering grounds. Thus, it is of crucial importance that they rapidly adjust their behaviour and diet to benefit from peaks of prey abundance, in particular during migration, when they need to accumulate energy at a fast pace. In this study, we compared foraging be...

Oral participation (OP) in class is an important factor contributing to the development of oral fluency. Recent studies in language learning have addressed the necessity of classroom interaction, or rather students’ oral participation in class. A correlational research study was drawn upon to measure the oral participation and factors affecting oral activities of the ELT students studying at th...
