INTRODUCTION The conversion of synthesis gas to methanol is practiced commercially in gas phase fixed bed reactors over a Cu/Zn/Al,O1 catalyst. However, because of the highly exothermic nature of the synthesis reactions, heat dissipation has been a bottleneck in the reactor design and process configuration. Moreover, coalderived synthesis gas, having a low H,/CO ratio, is not suitable for use i...

This study sought to examine risk and onset patterns in anorexia nervosa (AN), bulimia nervosa (BN), and binge eating disorder (BED). Women with AN (n=71), BN (n=66), BED (n=160) and non-psychiatric controls (n=323) were compared retrospectively on risk factors, symptom onset, and diagnostic migration. Eating disorder groups reported greater risk exposure than non-psychiatric controls. AN and B...

AIM This study compared functioning and productivity in individuals meeting Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) diagnostic criteria for binge eating disorder (BED) to those without BED. METHODS A sample of US adults from the National Health and Wellness Survey completed an Internet survey in October 2013. In addition to BED diagnostic criteria, the sur...

The role of olfactory cues such as carbon dioxide, pheromones, and kairomones in bed bug, Cimex lectularius L. behavior has been demonstrated. However, the role of vision and mechanoreception in bed bug behavior is poorly understood. We investigated bed bug vision by determining their responses to different colors, vertical objects, and their ability to detect colors and vertical objects under ...

Bed bugs, Cimex lectularius L. (Hemiptera: Cimicidae), are a fast-growing urban pest of significant public health importance in the United States and many other countries. Yet, there is very little field research on the ecology of this pest due to its near absence in the United States and most developed nations for several decades. We investigated characteristics of the bed bug infestation and ...

BACKGROUND the design and use of bed rails has been contentious since the 1950s with benefits including safety, mobility support and access to bed controls and disadvantages associated with entrapment and restraint. OBJECTIVE to explore which bed designs and patient characteristics (mobility, cognitive status and age) influence the likelihood of rails being used on UK medical wards. METHOD ...

[1] A mechanistic model is derived for the rate of fluvial erosion into bedrock by abrasion from uniform size particles that impact the bed during transport in both bed and suspended load. The erosion rate is equated to the product of the impact rate, the mass loss per particle impact, and a bed coverage term. Unlike previous models that consider only bed load, the impact rate is not assumed to...

in this paper, effects of the cross shore and groyne wall slopes on flow parameters around an impermeable groyne were considered using a three-dimensional numerical cfd model (i.e., fluent). the k-ε turbulence model was used to evaluate the reynolds stresses. the model was first applied to a vertical groyne on a flat bed and the model results were compared with the relevant experimental data. t...
