Laboratory experimentation has a vital role in science education. With the potential offered by information and communication technologies for educational domain, virtual laboratories have emerged as valuable alternative to face-to-face, hands-on laboratories. Moreover, possibility of opens new perspectives higher education sustainability. They are perfect approach training learners understand scientific principles many fields offering them illustrate phenomena through automated practical...

Background Cricoid cartilage pressure induced to prevent pulmonary aspiration from regurgitation of gastric contents has been recommended, and its efficacy requires a force greater than 40 Newtons. For occur, both an increase in relaxation the lower esophageal sphincter (LES) are necessary. However, effect cricoid on LES is unknown. This study evaluated effects human volunteers. Methods Lower barrier pressures (which equals pressure-gastric pressure) were measured using manometric method...

Many researchers have underlined the benefits of student mobility in strengthening their communication skills. Studying a foreign language and fostering knowledge about behavioural attitudes are most common research cases. One major issues mobility, by its very nature, is that it implies significant travel accommodation costs. Virtual or Exchange (VE), can be introduced as proactive alternative solution. This work presents an evaluation telecollaborative online course model organised VE...

Caudal regression syndrome (CRS) is a spectrum of disorders caudal vertebral agenesis or dysgenesis, involving the spinal column, that associated with other congenital anomalies. The majority cases are sporadic but maternal pre-gestational diabetes main risk factor. Imaging an integral part management syndrome. Antenatal diagnosis on obstetric ultrasound and evaluation fetal MRI ideal. Early postnatal and/or detailed essential for early to improve outcomes.

The increasing number of enlistees claiming their right to enroll in the programs African Universities and limited Higher Education Institutions (HEIs) were prime reasons students overcrowding classes. Massive Open Online Courses (MOOCs) showed a potential help limiting challenges massification open access HEIs. As literature review MOOC situation Africa is still nascent, we will qualitatively share experience Cadi Ayyad University Marrakech, Morocco (UCA) launching for its learners as case...

Objective In mechanically ventilated patients, pulmonary gas exchange was investigated during the administration of total parenteral nutrition containing medium-chain triglycerides or long-chain as fat emulsions. Design Prospective, randomized, crossover trial (two lipid infusion periods 8 hrs). Setting Intensive care unit in a university hospital. Patients Six using pressure-support mode. Interventions Total caloric intake adapted according to measured energy expenditure. Fat emulsion...

Administration of muscle relaxants is considered as necessary to prevent high intraabdominal and peak inspiratory pressures induced by pneumoperitoneum during laparoscopy. In the present study, we hypothesized that neuromuscular block does not alter pulmonary or abdominal elastic properties in pigs receiving general anesthesia. To test this hypothesis, changes airway pressure elastance CO(2), insufflation from 0 15 mm Hg were recorded anesthetized pigs, with without relaxants. A 100%...

Poly(o-toluidine) (POT) thin films were synthesized by electrochemical polymerization under cyclic voltammetric conditions from o-toluidine monomer in an aqueous solution of HCl as a supporting electrolyte. The electrosynthesized characterized UV-Visible, FT-Raman, and FTIR spectroscopies. optical transmissions the as-deposited measured 400–900 nm wavelength range. These measurements showed that band gap polymer is order 2.52 eV. FT-Raman POT film composed imine amine units. ITO/POT/Al...

Open education is one of the most important settings in every society.It grants everyone right to learn freely.Today, technology helping make learning even more open by providing an environment online education, which plays a remarkable role shortening distances and encouraging students learn.At Cadi Ayyad University (UCA) new-enrolled are facing linguistics barriers as well overcrowding classrooms, particular for those access institutions.Subsequently, they cannot have easy their...

For induction of anaesthesia, drugs such as propofol are commonly administered according to a per weight basis. However, primarily distributed the fat-free mass. This study was undertaken determine relationship between requirement for and body mass determined by bioimpedance analysis (BIA) or index (BMI).Twenty-one ASA 1 female patients scheduled gynaecologic surgery received at 133 mg.min-1. Stepwise regression used describe relationships loss consciousness age, weight, lean measured BIA...

This work presents the UC@MOOC project as a pedagogical innovation to face effects of massification that are making Moroccan universities endure many constraints for past ten years, well other African universities. It aims, among its objectives, cope with factor and overcome language difficulties encountered by students. In this project, our top priority is reduce academic failure then we will get point responding training' needs. Courses scripted posted online which did not require...

Since their emergence just over a decade, the Open Educational Resources (OER) have been essential in development of educational strategies and policies many countries. The first part this article describes briefly state art terms definitions applications OER. Then we will focus on adoption OER at Cadi Ayyad University. In particular, present discuss some initiatives developed Finally, challenges facing our university within different factors.
