the management of water table is introduced as one of the major parts of the solutions in water resources management. this method could play a significant role in protecting water resources, increasing irrigation efficiency, preserving nutrients in soil, and protecting the quality of surface downstream, and as well, of groundwater. towards this end, a laboratory study has been done on the effec...

sulfuric acid production plants are one of the main sources of sulfur oxides, emission to the atmosphere. in the present study to control sulfur oxides of sulfuric acid plant two methods have been selected. the first method is desulfurization by ammoniac (plant a) and the second one is a combination of the first method and dry scrubbing process with calcium hydroxide as the absorbent material) ...

en examinant une serie de composes homologues tels que, les hydrocarbures, les alcools, les acides organiques, etc. on remarque les points d'ebullition et de fusion croissent avec la masse moleculaire, neanmoins, il n'ya aucune relation simple entre le point d'ebullition, ou le point de fusion et la grandeur moleculaire en comparant des molecules de types differents. l'align...

Depuis le début de l’année 2018, il a été constaté une prolifération croissante et désormais bien documentée d’algues sargasses sur les côtes des îles la Caraïbe dont Martinique. L’échouage ces algues brunes constitue non seulement un désastre environnemental économique, mais pourrait également résulter en impact sanitaire pour population malgré peu données biomédicales disponibles. Après 48 h ...

Although chemistry is widely considered among its practitioners to be a modern science, technological processes based on chemical reactions have been in standard use from the distant past. The production of salts, dyes and paints, cosmetics, and fermented beverages made use of techniques and reactions common to chemical experimentation (such as filtration, dissolution, and sublimation). Among t...

Mercury is present in the world in very small amounts, but it has played a very important role in the development of alchemy, extraction of gold and silver, in the chloro-alkali industry, batteries, construction of scientific instruments, treatment of illnesses, and pest control. Increasing environmental concerns are leading to a significant reduction in annual production and to its substitutio...

Staying within an objectual interpretation of the quantifiers, perhaps the simplest way to make systematic sense of expressions like ' x believes that P ' and closed sentences formed therefrom is just to construe whatever occurs in :he nested positior. held by 'p', 'g', etc. as there having the function of a singular term. Accordingly, the standard connectives, as they occur between terms in th...
