The leaching behaviors of enrofloxacin (ENR), a fluoroquinolone group antibiotic, in three different standard soils, namely sandy, loamy sand and sandy loam were investigated according to OECD guideline 312. In addition, the effects of tenside, sodium dodecylbenzenesulfonate (DBS) on the mobility of ENR in two different soils were studied. The mobility of ENR in all three standard soils was ver...
peace and national security protection and ironic solving of international conflicts become the preliminary foundation of the united nations charter and had been considered as the main responsibilities of the security council, after world war ii and the establishment of united nations organization. therefore, the security council enables to analyze every kind of conflicts and challenges which ...
Gypsum is the most common sulfate mineral in soils of arid and semi-arid regions. Two hundred million hectares of the earth’s surface and about 28 million hectares of Iranian arid soils are covered by gypsiferous soils. The studied soils consist of alluvial plane and eolian plains in northern Iran. Soils were classified as Haplocambids, Aquisalids and Endoaquepts. In this study, genesis, format...
it is definitely necessary to understand the concept and behavior of causation of life insurance policies and its determinants for insurance managers, regulators, and customers. for insurance managers, the profitability and liquidity of insurers can be increasingly influenced by the number of causation through costs, adverse selection, and cash surrender values. therefore, causation is a materi...
this study intends to investigate samuel beckett’s waiting for godot and endgame under the lacanian psychoanalysis. it begins by explaining the most important concepts of lacanian psychoanalysis. the beckettian characters are studied regarding their state of unconscious, and not the state of consciousness as is common in most beckett studies. according to lacan, language plays the sole role in ...
development of argillic horizon in loess derived soils under xeric and udic soil moisture regimes was studied in golestan province. soils were classified as hapludalfs and haploxeralfs. high leaching, stability of the surface, forest vegetation,structure and well drainage conditions provide appropriate conditions for clay migration through the profile and formation of argillic horizons. in the ...
topography and climate are two important soil forming factors affecting genesis and clay mineralogy of soils. calcareous and gypsiferous soils are widely spread in arid and semiarid parts of iran and palygorskite is a dominant clay mineral in these soils. the objectives of the study were to: (1) determine soil genesis and classification along the climotoposequence and (2) investigate clay miner...
وضعیت پتاسیم در خاکهای تحت کشت گندم و ارتباط آن با پتاسیم دانه در منطقه داراب، جنوب شرقی استان فارس
The status of soil K forms and its relationship with K content in wheat grain at harvest period may be important for nutrient fertility management. For this purpose, 40 surface (0-20 cm) and subsurface (20-40 cm) soil samples and also grain samples from wheat fields of Darab region were randomly sampled in 2014. Then physicochemical properties of the soils and the contents of soluble, exchangea...
introduction: the accumulation of heavy metals (hms) in the soil is of increasing concern due to food safety issues, potential health risks, and the detrimental effects on soil ecosystems. hms may be considered as the most important soil pollutants, because they are not biodegradable and their physical movement through the soil profile is relatively limited. therefore, root uptake process may p...
