Wall-to-bed (or wall-to-fluid) heat transfer issues in trickle bed reactors (TBR) has an important impact on operation and efficiency in this category of reactors. In this study, the hydrodynamic and thermal behavior of trickle bed reactors was simulated by means of computational fluid dynamics (CFD) technique. The multiphase behavior of trickle bed reactor was studied by the implementation of ...

Bed bugs appear to be feared more than vector insects and other household pests. The reasons for this exaggerated fear are not fully understood. One hypothesis is that the folk knowledge on recognising and controlling bed bugs decreased as bed bugs became rarer in the 1960s and led to irrational perceptions. Here, we examine people's ability to recognise a bed bug and their response what to do ...

in this paper the effectiveness combination of bed sill and collar in reduction of local scour depth at cylindrical piers under clear water flow condition was investigated (v/vc=0.9). in the first of experiments, the bed sill was located in downstream and different distances from the piers. results indicated that minimum distance of the bed sill from the piers in downstream has maximum reductio...

Before passing to the principal aspect of this subject it is necessary to consider first the train of reactions which are known to set in when a person is subjected to physical trauma, and then to appreciate their bearing on dietary requirements. It is also important to note the influence of the patient's physiological condition at the time of trauma on the subsequent sequence of events. In cas...

The combined program of chemotherapy with potent antimicrobial agents and decreased application of bed rest provided broad opportunities to expand rehabilitation services and to assist hospitalized tuberculous patients in all areas of social, emotional, and vocational adjustment,”2 Thus, at National Jewish Hospital, it became possible to offer a variety of rehabilitation services specifically d...

Planning for mass gatherings involves health system preparedness based on an understanding of natural and technological hazards identified through prior risk assessment. We present the expected hazards reported by health administrators of the host cities for the 2014 FIFA World Cup in Brazil and discuss the hazards considering minimal available public hospital beds in the 12 cities at the time ...

The effect of tillage, crop establishment and weed management was studied on theperformance of wheat grown after soybean at New Delhi, India during 2010-11 to 2011-12.Sixteen treatment combinations involved 2 tillage, viz. conventional tillage (CT) and zero tillage(ZT), two crop establishment practices, viz. raised-bed and flat-bed and four weed management,viz. isoproturon + hand weeding, mesos...

Turbidity currents in the ocean and lakes are driven by suspended sediment. The vertical profiles of velocity and excess density are shaped by interaction between the current and bed as well as between the current and the ambient water. This paper presents 48 series of experiments in which saline gravity currents flow through a laboratory sinuous flume. flume contains three successive bends wit...
