The aim of our study is to evaluate the knowledge regarding physical medicine and rehabilitation among physicians in training and medical students at the Mohammed VI University Hospital in Marrakech, to approach the knowledge, attitudes, and practices of doctors regarding physical medicine and rehabilitation and evaluate the knowledge in theoretical training related to PRM among the students. We conducted a monocentric cross-sectional analytical study, using a web-based anonymous survey, carried out among 558 undergraduate student and training doctors, randomly selected in the form of a survey on the knowledge towards Physical Medicine and rehabilitation. We received 558 survey duly completed by students of the Faculty of Medicine and Pharmacy of Marrakech (62.4%) and training doctors (37.6%). The mean age of the participants was 24.53 ± 3.9 years, with extremes ranging from 17 to 39 years. 52.7% of the participants were from the former educational reform, The predominance of participation was remarkable among pediatricians 23%, The population who knew PRM was the majority (79.3%), 40.7% of the participants were unaware of the availability of a PRM department at Mohamed VI University Hospital, 0.5% of all training doctors and medical students questioned strongly agreed with the sufficiency of their training in disability management were belonging to the new reform, 84.1% of participants had never attended or referred a patient to the PRM department. 23.2% of training doctors affirmed the referral of patients to PRM for further management. Despite the essential role of PRM in the management of diseases, it remains little known by training doctors and medical students. This lack of knowledge of PRM reflects the lack of the undergraduate and postgraduate of the medical education in the field of rehabilitation.

The behavior of the quantum correlations, information scrambling and the non-Markovianity of three entangling qubits systems via Rashba is discussed. The results showed that, the three physical quantities oscillate between their upper and lower bounds, where the number of oscillations increases as the Rashba interaction strength increases. The exchanging rate of these three quantities depends on the Rashba strength, and whether the entangled state is generated via direct/indirect interaction. Moreover, the coherence parameter can be used as a control parameter to maximize or minimize the three physical quantities.

采用电化学阻抗谱(EIS)和电位极化(Tafel)试验,研究了在环氧树脂涂层中添加含铝粉末以增强碳钢基材的防腐性,含铝粉末包括纯铝、Al/CNT、Al/Al_(2)O_(3)、Al/CNT/Al_(2)O_(3)。用球磨法合成含2 wt.%碳纳米管、2 wt.%氧化铝纳米颗粒的复合粉末,然后以1 wt.%的浓度加入到环氧树脂涂层中。结果表明,由于环氧树脂复合涂层的防护性能增强,从而提高了其耐腐蚀性。研究还发现,Al/CNT/Al_(2)O_(3)复合添加剂的保护性能比其他添加剂更显著,因为其颗粒尺寸的减小和具有某些形状的颗粒,进一步减少了腐蚀环境通过涂层渗透的路径,避免了金属基底/涂层界面可能发生的反应。EP-Al/CNT/Al_(2)O_(3)保持了一次时间常数特性,并在整个暴露时间内表现出最高的阻抗和最强的稳定性。这些添加剂的存在增强了涂层,从而改善了涂层的屏障性能。
