Understanding the interaction between bacterial cells and solid surfaces is essential to our attempts to quantify and predict the transport of microbes in groundwater aquifers, whether from the point of view of contamination or from that of bioremediation. The sorption of bacterial cells suspended in groundwater to porous medium grains was examined in batch studies. Bacterial sorption to clean ...

Purpose: In the eye lens, cytosolic protein concentrations increase progressively from periphery to center, contributing gradient of refractive index (GRIN). Aquaporins are membrane proteins lens fiber cells that regulate water transport and adhesion interact with cytoskeletal proteins. This study investigates how these contribute proper development GRIN. Methods: Loss-of-function deletions aqp...

RATIONALE, AIMS AND OBJECTIVES Double checking is a standard practice in many areas of health care, notwithstanding the lack of evidence supporting its efficacy. We ask in this study: 'How do front line practitioners conceptualize double checking? What are the weaknesses of double checking? What alternate views of double checking could render it a more robust process?' METHOD This is part of ...

The chemical abundances of the very metal-poor double-enhanced stars are excellent information for setting new constraints on models of neutron-capture processes at low metallicity. These stars are known as s+r stars, since they show enhancements of both s-process and r-process elements. The observed abundance ratios for the double-enhanced stars can be explained by those of stars that were pol...

purpose : contrast sensitivity (cs) evaluation by sv–1000e chart in all spatial frequencies after micro incision cataract surgery (mics) and its comparison between two thin lenses after optical correction in natural and glare conditions methods : in this cross sectional study, 100 eyes having mics with dodick arc phacolaser system were evaluated. 50 thinoptx lenses and 50 acrismart lenses were ...

A detailed field-scale investigation of processes controlling the architecture, persistence and dissolution of a 20 to 45year old trichloroethene (TCE) dense non-aqueous phase liquid (DNAPL) source zone located within a heterogeneous sand/gravel aquifer at a UK industrial site is presented. The source zone was partially enclosed by a 3-sided cell that allowed detailed longitudinal/fence transec...
