Study Of Concrete Mixture Using Sea Sand With Fresh Water and Sea Water Cure

Possibility of Sea Water as Mixing Water in Concrete

In the near future, fresh water will be very difficult to get and scarce. It is said that in 2025 half of the mankind will live in the areas where fresh water is not enough. Also, UN and WMO are predicting 5 billion people will be in short of even drinking water. Also, in the present, there are some areas where sea water or chloride contained sand are used as mixing water with or without intens...

Corrosion of Concrete in Sea Water (RESEARCH NOTE)

Attack and disintegration of concrete structures under the influence of aggressive fluids, wet gases, etc. are understood as corrosion of concrete. The corrosion of concrete is a chemical, colloidchemical process, yet often a physico-chemical one, while that of reinforced concrete supported oil platforms are subjected to marine environment in the Persian Gulf and therefore corroded. In the pres...

Fresh water and sea water drowning; a study of the terminal cardiac and biochemical events.

Mechanism of circulatory failure in fresh and sea water drowning.

O LDER concepts as to the cause of death from drowning postulated that spasm of the glottis prevents entry of water into the lungs, that impairment or cessation of the heart beat is due to asphyxia and that use of artificial respiration offers the greatest chance for revival. Recent experimental studies have revealed that this mechanism is dominant in a minority of cases only: 20 per cent in ou...

Transcriptomic Analysis of Trout Gill Ionocytes in Fresh Water and Sea Water Using Laser Capture Microdissection Combined with Microarray Analysis

Fish gills represent a complex organ composed of several cell types that perform multiple physiological functions. Among these cells, ionocytes are implicated in the maintenance of ion homeostasis. However, because the ionocyte represents only a small percent of whole gill tissue, its specific transcriptome can be overlooked among the numerous cell types included in the gill. The objective of t...
