The role of nitrite (NO2−) and nitrate (NO3−) is essential in the global nitrogen cycle. Monitoring their concentration environmental industrial aqueous samples, surface water, soil, food agricultural products are high importance. Especially, effect anthropogenic emission, i.e., intensified agriculture due to overuse nitrogen, phosphorus potassium fertilizers. most widely utilized methods for d...

This research pertains to a new class of liquid bandage polymers which are promising for assisting advanced wound healing by serving as substrates to promote cell viability and proliferation. Amphiphilic nitrogen-containing polymer poly (3-methacryloyloxypropyltris (trimethylsiloxy)silane-co-N-isopropylacrylamide) (poly (TRIS-co-NIPAM)) was synthesized and investigated with further comparison t...

Dahmen, H., Staub, Th., and Schwinn, F. J. 1983. Technique for long-term preservation of phytopathogenic fungi in liquid nitrogen. Phytopathology 73:241-246. Survival, pathogenicity, and sporulation of 31 phytopathogenic fungi temperature or in water at 20 or 40 C. For successful recovery, all (including species from the Myxomycetes, Oomycetes, Ascomycetes, Oomycetes and Colletotrichum lagenari...

Mammals have lungs to breathe air and they have no gills to breath liquids. When the surface tension at the air-liquid interface of the lung increases, as in acute lung injury, scientists started to think about filling the lung with fluid instead of air to reduce the surface tension and facilitate ventilation. Liquid ventilation (LV) is a technique of mechanical ventilation in which the lungs a...

Nowadays Ionic Liquids (ILs) salts becomes a major class of attention due to their numerous industrial applications in various fields such as softest solvents, catalysts, batteries, wastewater treatment…etc. In this review, we highlight and present ionic liquid nitrogen-based both aliphatic aromatic compounds. Aliphatic based nitrogen liquids are prepared from different sources like trimethylam...

The fine structure of the regular arrays of subunits seen on both plasmalemma fracture faces in resting and starved Saccharomyces cerevisiae (baker's yeast) has been compared using different freeze-fracture replication methods. Freeze-cleaving was carried out at 173 degrees, 133 degrees, and 108 degrees K under a vacuum of 2 X 10(-7) torr (2.6 X 10(- 7)mbar) or under liquid nitrogen at atmosphe...

OBJECTIVE To assess the feasibility of refreezing human semen using the technique of liquid nitrogen vapor with static phases. MATERIALS AND METHODS Twenty samples from 16 subjects who required disposal of their cryopreserved semen were thawed, corresponding to 6 cancer patients and 10 participants in the assisted reproduction (AR) program. Samples were refrozen using the technique of liquid ...
