The article considers the problems of regulating seawater level in absorber for removing carbon dioxide from a hydrogen mixture. Decreasing or increasing water lead to its low operation efficiency, pressure being constant various modes operation. feed valve’s main function is maintain necessary level. There has been given functional diagram channel controlling valve regulator with task signal a...

Phosphorus (P) and suspended sediment (SS) play a pivotal role in influencing water quality and biodiversity and, as a result, controlling the transfer of these important diffuse pollutants from land to water, represents a priority task for catchment managers and stakeholders (Kronvang et al., 2005a). This review briefly summarises the environmental and legislative context regarding phosphorus ...

A wide range of biorelevant applications, particularly in pharmaceutical formulations and the food and cosmetic industries, require the stabilization of two water-soluble blended components which would otherwise form incompatible biphasic mixtures. Such water-in-water emulsions can be achieved using Pickering stabilization, where two-dimensional (2D) nanomaterials are particularly effective due...

1. Chemical stimulation as a function of temperature was studied by using oxalic acid in fresh and salt water and malonic acid in salt water as stimulating agents on Fundulus. According to the Arrhenius equation the following micro values were obtained for the various acid solutions between 0 and 29 degrees C.: for 0.002N oxalic in fresh water-15,800; 33,000; for 0.0008N oxalic in fresh water-1...
