Aim:The present study assesses the nurse managers’perception of clinical ***:A cross-sectional,descriptive,non-experimental quantitative research design was utilized in three governmental hospitals in Madinah Munawara city for a purposive sample of different levels of nurse managers(n=84)by using a ***:The total knowledge of nurses managers regarding clinical supervision domains,where 59.5%of participants had a high level of knowledge,with mean±standard deviation(47.262±11.151).The highest mean was in the clinical supervision-facilitating learning domain(18.464±4.155),with 69%of participants having a high level of knowledge regarding this *** and quality in the clinical supervision domain represent the lowest mean of knowledge(4.607±1.628).The level of total skills of nurses managers regarding clinical supervision domains,where 54.8%of participants had a high level of total skill while the range 19-60,with mean±standard deviation was(44.167±8.958).The highest mean was in the c linical supervision-f acilitating learning domain(17.405±3.671),with 48.8%of participants having an increased knowledge of this *** and quality in the clinical supervision domain represent the lowest mean of skills(3.952±1.270),with more than half 58.3%of nurse managers having average skills in the same ***:In the Al-Madinah region,there is no single policy or system of clinical supervision;rather,it is based on the needs of each *** supervision should be handled appropriately and *** management should offer proper training for newly appointed first-line nurse managers with adequate,regular,and timely feedback on their strengths and weaknesses in their *** supervision should be taught as a separate curriculum in nursing administration *** managers should create a system,culture and environment that fosters high ethical standards and competent clinical *** rig

Pedestrian flow through narrow exits is one the most important features of crowd dynamics and *** is a particularly important aspect of pedestrian simulation models in that the accuracy is highly dependent on their ability to produce realistic exit flow *** firstly identified the four parameters that are most critical for physical interactions of the social force model and then calibrated them against two well-controlled pedestrian *** these calibrated parameters,we discussed the reasonable settings of sensitive parameters for different levels of pedestrian ***,we revisited the basic questions about the effect of the exit location,the bottleneck length,and the effect of obstacles on pedestrian *** simulation results indicated that:(1)The effect of the exit location on the pedestrian egress efficiency is uncertain,and the evacuation efficiency is also related to the exit width and the level of urgency.(2)The"pass-way"after the exit also named as the bottleneck length has a negative impact on the evacuation performance only in the scenarios that the bottleneck length is not more than 2.0 *** the bottleneck length exceeds 2.0 meters,pedestrian outflow efficiency reaches an asymptotic.(3)Setting an obstacle near an exit is not leading to a longer pedestrian evacuation time,instead,it is effectively improving pedestrian evacuation.

Neonatal hyperbilirubinemia is a common phenomenon shortly after birth and a frequent cause of prolonged hospitalization[1].Increased enterohepatic circulation of indirect bilirubin is one of the elucidated mechanisms implicated in the pathophysiology of neonatal hyperbilirubinemia[2,3].According to various in vitro and in vivo evidence from animal[3]and human[2]trials,zinc salts have been depicted to reduce bilirubin levels.
