Comprehensive field observations characterizing the biological carbon pump (BCP) provide foundation needed to constrain mechanistic models of downward particulate organic (POC) flux in ocean. Sediment traps were deployed three times during EXport Processes Ocean from RemoTe Sensing campaign at Station Papa August–September 2018. We propose a new method correct sediment trap sample contamination...

Arsenic (As) fractions in the sediments of seven lakes from East Plain Ecoregion and six lakes from Yungui Plateau Ecoregion, China, were investigated. Results indicated that the total As concentrations in sediment samples of lakes of the East Plain Lake Ecoregion are higher than those of Yungui Plateau Lake Ecoregion. Residual As is the main fraction in sediment samples of lakes from both ecor...

حدت استافیلوکوکوس اورئوس اساساً توسط پروتئین­های مرتبط با دیواره­ی سلولی و ترشح توکسین­ها تعیین می­گردد، که بیان آن­ها تا حد زیادی توسط سیستم­های تنظیمی دو جزئی (tcrss) مثل سیستم­های تنظیم ژنی فرعی (agr) و rap-trap تنظیم می­شود.  تاکنون چهار واریانت آللی از agr (agr i-iv) و trap (trap 1-4) شناسایی شده است.  برخی از گزارش­ها اظهار داشته­اند که تمایلات بالینی بر طبق هر گروه agr وجود دارد، اما  اطل...

Overland flow connectivity and runoff and sediment trap effectiveness are currently the cutting edge topics in soil erosion research. The effect of agricultural terraces, irrigation channels and trails on runoff and soil erosion modelling at catchment scale is still a remaining research question. In this study we run the index of connectivity of Borselli et al. (2008) and a modified version of ...
