Does The Critical Shields Stress For Sediment Transport Depend On Channel-Bed Slope?, Ishraq Alfadhli, Shu-Qing Yang, Muttucumaru Sivakumar

This paper investigates why the observed critical Shields stress for incipient sediment motion deviates from the Shields curve. This deviation is often described in the literature as due to measurement errors and non-uniformity of channel-bed slope or flows. On the contrary, this paper hypothesises the deviation as due to the presence of vertical velocity in open channel flows. We found that the existence of vertical velocity in non-uniform flows can lead to the deviation of critical shear stress from the standard Shield's diagram that is valid only in uniform flows, and the channel bed slope could not contribute to the …

Background: Prostate cancer (PCa) patients suffer from identifiable stressors that may cause them anxiety and/or depression. In a previous study, an initial exploration of the ways in which PCa patients seek to cope with those stressors was described. However, several methodological limitations prevented direct comparisons of the relative effectiveness of patients’ coping strategies. To further investigate this issue, a standardised format was used to present the most commonly-used coping strategies to a new sample of PCa patients and to compare the effectiveness of those strategies. Methods: A total of 147 PCa patients completed a background questionnaire and the Prostate Cancer …
