Dynamics of bacterial assemblages following anoxia in the hypolimnion of a eutrophic lake (Lake Aydat) were characterized. The sampling started in spring before complete anoxia and was continued weekly until complete mixing of the water column occurred in autumn. Bacterial community patterns at 3 sampled depths (10, 12 and 14 m) were investigated using temporal temperature gradient gel electrop...
the purpose of this current study was to investigate the influence of perceptual-motor trainings on motor skills of girls with trainable mental retardation. so 20 girls with trainable mental retardation in the town of marivan welfare organization with the average of 8/3 ±1/11 years and iq of 39/14±6/84 with purposive sampling method were studied. all girls were pretested. then samples based on ...
Abstract Nutrient stratification of no‐till managed soil can affect test analysis levels plant‐available phosphorus (P). Research has suggested sampling to different depths due acidity, but little work been conducted investigate any change recommendations for immobile nutrients. The objective this study was determine the depth that had greatest relationship with yield response fertilizer‐P. sam...
abstract this study aimed at analyzing a corpus of emails gathered from iranian students studying in england. the corpus contained 996 emails that were investigated by employing the framework of chen (2006) to find common patterns in the discourse of these emails. another aim of the study was to find how two request acts (want statements and query preparatory) were used in the emails. the...

introdouction: it is important for the clinician to be aware regarding the necessary thickness of materials used as intra-orifice coronal barriers to prevent microleakage. the purpose of this in vitro study was to compare coronal microleakage of three different thicknesses of white and gray angelus mineral trioxide aggregate (wamta, gamta). materials and methods: a total of 66 canals of extract...
Observations in the littoral zone of a large lake (Lake Constance) revealed strong and periodic fluctuations of temperature and current velocity on timescales between 10 and 15 min associated with high-frequency internal waves. The peak in the spectral energy of the current velocity fluctuations associated with high-frequency internal waves follows the seasonal dynamics of stratification, descr...

A manned submersible was used in a fjord in southeastern Alaska to study the distributional patterns of the red king crab (Paralithodes camtschaticus) and the Tanner crab (Chionoecetes bairdi) in summer. The cove was divided into three zones: inner, middle, and outer. Six types of habitats, including sand-mud, rock, shell, debris, rock wall, and algae, were identified from video tapes. A relati...
