Distribution Of Reynolds Shear Stress In Steady And Unsteady Flows, Ishraq Alfadhli, Shu-Qing Yang, Muttucumaru Sivakumar
Distribution Of Reynolds Shear Stress In Steady And Unsteady Flows, Ishraq Alfadhli, Shu-Qing Yang, Muttucumaru Sivakumar
Ishraq Hamdan Alfadhli
This study investigates the Reynolds shear stress distribution in steady and unsteady non-uniform flows. Specifically, it deals with how to express the deviation of this turbulence characteristic from that of uniform flow line; it is found that flow acceleration can well represent the deviation of Reynolds shear stress from its standard linear distribution. By connecting the flow acceleration with Reynolds shear stress, the study demonstrates empirically that the linear distrubiton of Reynolds shear stress can be observed when the flow acceleration is zero; the concave distribution of Reynolds shear stress can be observed when the flow acceleration is negative or …
Does The Critical Shields Stress For Sediment Transport Depend On Channel-Bed Slope?, Ishraq Alfadhli, Shu-Qing Yang, Muttucumaru Sivakumar
Does The Critical Shields Stress For Sediment Transport Depend On Channel-Bed Slope?, Ishraq Alfadhli, Shu-Qing Yang, Muttucumaru Sivakumar
Ishraq Hamdan Alfadhli
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 …
Depression, Anxiety, And Stress Among Mothers Of Healthy Children And Mothers Of Children With Cochlear Implants, Seyed Mohammad, Kalantarkousheh, دکتر سید محمد کلانتر کوشه
Depression, Anxiety, And Stress Among Mothers Of Healthy Children And Mothers Of Children With Cochlear Implants, Seyed Mohammad, Kalantarkousheh, دکتر سید محمد کلانتر کوشه

Background: The birth of a disabled child is one of the resonant factors that can cause family disorders. Mothers who have disabled children experience different levels of anxiety and stress. Decreased hearing, meanwhile, is one of the major reasons for disability. Parents have different concerns about their children’s development and social relations. Cochlear implantation is a new way to cure deafness and enables the disabled child to hear, talk, and communicate. This research intends to compare the outbreak of depression, anxiety, and stress among mothers who have healthy children and those of cochlear implantation children. Additionally, the research examines if …
How Prostate Cancer Patients Cope: Evaluation And Refinement Of The Prostate Cancer Patients' Coping Strategies Questionnaire, Christopher Sharpley, Vicki Bitsika, David Christie
How Prostate Cancer Patients Cope: Evaluation And Refinement Of The Prostate Cancer Patients' Coping Strategies Questionnaire, Christopher Sharpley, Vicki Bitsika, David Christie

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 …

Clusterin is a usually secreted glycoprotein with chaperone properties. Recently, it has been suggested that clusterin isoforms reside in the nuclear and cytosolic compartments of human cell types, where they can influence various cellular programs including DNA repair, transcription and apoptosis. Several mechanisms have been proposed to explain this atypical location, including alternative transcription initiation and alternative splicing. However none of these have been unequivocally established as occurring in live cells. Here we provide direct experimental evidence that in live intact cells, under certain stress conditions, clusterin can evade the secretion pathway and reach the cytosol. This was demonstrated using …
The Lived-Experience Of Leading A Successful Police Vehicle Pursuit: A Descriptive Phenomenological Psychological Inquiry, Rodger E. Broome Phd
The Lived-Experience Of Leading A Successful Police Vehicle Pursuit: A Descriptive Phenomenological Psychological Inquiry, Rodger E. Broome Phd
Rodger E. Broome
Police vehicle pursuits are inherently dangerous, rapidly evolving, and require police coordination to safely stop and arrest the suspect. Interviews of three US police officers were conducted and the descriptive phenomenological psychological method was used to analyze their naïve accounts of their lived-experiences. The psychological constituents of the experience of leading a successful chase and capture of a fleeing criminal found are: (1) Alert to Possible Car Chase, (2) Suspect Identified, (3) Anxiety and Excitement About the Chase, (4) Awareness of Primary Chase Role, (5) Radio Coordination with Others to Take Actions to Stop the Suspect, (6) Ongoing Evaluation of …
