Abstract Background and Aims Central line-associated bloodstream infections (CLABSI) lead to increased morbidity mortality in hemodialysis-dependent patients are costly treat. Devices such as hemodialysis connector caps (Tego) antimicrobial barrier (ClearGuardHD) represent promising interventions reduce CLABSIs. The aim of this study was assess the efficacy these devices reducing CLABSIs who us...

ABSTRACT The Bikou Terrane, located at the conjunction of Longmenshan fold-thrust belt and west Qinling orogenic in centeral China, was involved Late Triassic collision between South China North blocks. Terrane has preserved crucial information on structural geometry kinematics tectonics, is therefore great importance for reconstructing Paleo-Tethyan evolutionary history. However, multi-phase t...

based on the importance and role of species diversity and richness as ameasurement of the health of an ecosystem; studying of their components can lead toevaluate the health condition of rangeland. this research was carried out in a part ofhighland mountainous rangeland of mount alborz range in iran. diversity and richnesswere assessed as an ecosystem health indicator. the study area was locate...

surface oil seeps from alasht, lapur and jenesem share many compositional affinities including distributions and concentrations ofnormal alkanes, terpanes and steranes. these oils also show many similarities with that of jurassic sediments (shemshak group, klarizformation) systematically sampled from the galandrud coal mine. recent geochemical studies in this area indicated that theshemshak gro...

a faunistic review is given on the iranian medically important spiders of two genera loxosceles and latrodectus. latrodectus cinctus blackwall, 1865 is reported for the first time from iran (and for the second time from asia) and is replaced with the previous erroneous reports of l. hasseltii thorell, 1870. the following species are reported for the first time from the listed provinces: loxosce...

The aim of this study was the spatial and temporal monitoring soil erosion patterns in Iran. G2 model used, as an appropriate tool to provide required month-time step country-wide loss maps statistical outputs. input parameters were derived with field surveys remote sensing imagery (MODIS, SRTM, SPOT, Sentinel-2 scenes). An innovation for consideration snow cover effect on rainfall erosivity. I...
