Interprofessional Practice is a key factor in initiatives designed to increase the effectiveness of health services currently and reduced conflicts among health professionals.collaborative practice in health organizations achieved when healthcare professionals from different specialties provide complete services by working with patients, their families, specialists and communities to deliver the highest quality of care across all settings.Despite the long history and even recent high expansion of medical education in Sudan in the last three decades, few medical faculties implementing Inter Professional Education (IPE) as a learning system. This cross sectional study aims to investigate the perception of medical pharmacist toward interprofessional practice using modified Interprofessional Collaboration Model Questionnaire (PINCOM-Q) 56-item questionnaire was modified to measure perceptions of interprofessional practice. The sample size (n=65) included medical pharmacists who worked in eight governmental hospitals in Khartoum State. Sample size was small and geographically limited due to low number of pharmacist recruited on governmental hospital. Statistical insignificant difference perception towards interprofessional practice according to socio-demographic characteristic of the participants (P. value ≥ 0.05). We recommend for ministry of higher education,ministry of health and associated counsels to implement IPL activities, in health professional schools can give good impact in IPP.

Les huiles sont largement utilisées dans l’industrie et l’alimentation. L’Askarel parmiles huiles les plus utilisées dans la gamme industrielle pour leur stabilité chimique et leurisolation. Cependant, ces huiles sont à l’origine de la pollution une fois rejetée dansl’environnement.Actuellement, les techniques de traitement à l’acide et au charbon actif sont parmi lestechniques les plus efficaces pour éliminer les polluants.L’objectif de ce travail est focalisé sur l’utilisation de la technologie de traitement àl’acide sulfurique et du gypse /charbon actif pour régénérer l’huile d’Askarel, afin de leréutiliser à nouveau. Nous avons étudié l’efficacité du traitement en variant plusieursfacteurs, tels que la nature et le volume de l’acide, la nature d’adsorbant et sa quantité.Afin de valider le traitement nous avons mesuré des paramètres, tels que la densité, laviscosité, point d'écoulement, point d'éclair et l’indice d'acidité, nous avons utilisé aussi destechniques spectrales (IRTF et UV-Visible).

Notre étude porte sur l'adsorption des nitrates sur un matériau végétal. Nous avons testé plusieurs matériaux végétaux tels que : écorce d'orange, la paille, le résidus de mais et les tiges de dattes et il s'est avéré que les tiges de dattes constitue un meilleur adsorbant des nitrates. Une étude paramétrique a été effectuée pour examiner l'influence de la concentration du polluant, la masse et la granulométrie de l'adsorbant, le pH et la température de la solution sur le rendement d'adsorption. Le meilleur rendement d'adsorption (90%) est obtenu dans les conditions opératoires suivantes : Concentration des nitrates = 125 mg/l, pH = 2, concentration de l'adsorbant = 5g/l, granulométrie = 50µm. L'étude cinétique a montré que l'équilibre d'adsorption est atteint au bout des premières 20min de contact. L'isotherme d'adsorption du polluant sur les tiges de dattes obéit au modèle de Langmuir (R2 = 0.99), et la vitesse de la réaction est du pseudo second ordre.L'étude thermodynamique a montré que le processus d'adsorption des nitrates est spontané ( G<0), endothermique ( H>0) et l'affinité du matériau pour l'adsorption des nitrates est représenté par S>0. Les paramètres opératoires influences sont optimisées par un modèle trouvé par la méthode des plans des expériences

The rapid development in membrane technologies and their use as a filtration medium have been based on the use and development of new materials to improve system performance. Carbon nanotubes (CNTs) represent a class of promising nanomaterial, exhibiting outstanding mechanical, electrical, thermal conductivity and adsorption properties. The idea of using carbon nanotubes in the separation and filtration industry has been put forward, but constructing macroscopic structures with controlled density, porosity, and morphology has been a challenge.Buckypaper (BP) is a form of CNT film that is being investigated for application in water treatment. In BPs, the CNTs are oriented randomly into non-woven or paper like structure. This arrangement helps provide a large specific area with highly porous three dimensional network structures. However, the preparation of BP membranes with controlled porosity and pore size distribution entails taking into account many processing parameters.Porosity is a key property for the use of BPs in separation applications in general. The work conducted here aims at preparing BPs with controlled porosity through the investigation of three different parameters, which impact porosity. These entail the porosity of the supporting filter membrane during the preparation of the BPs, as well as the exposure of prepared BPs to different solvents vapors and for different exposure times. The retention performance of the obtained BPs in water filtration is tested using micro-sized polymer beads.CNT-BPs were prepared using vacuum filtration. Morphology and pore size distribution were investigated using scanning electron microscopy (SEM), nitrogen gas adsorption and mercury porosimetry. Different parameters were evaluated for their effect on tailoring the porosity of BPs. Statistical analysis was used to determine the effect of the three parameters investigated, namely (1) the pore size of the membrane filter used in the preparation of BPs from CNT dispersions, (2) type of solvent vapors to which the prepared BPs are exposed, and (3) the exposure time to the solvent vapors, on the final membrane porosity. Results indicated that the type of solvent affects the pore size distribution with DMF giving more pores in the smaller pore size ranges. In addition, variation of pore size distribution of the BP membranes was observed upon varying the pore size of the membrane filter. On the other hand, no significant change was detected on changing the time exposure to the boiling solvent. One variable and one combination of variables were found to be successful in producing BPs with a lower average pore size. The findings confirm the potential of the solvent evaporation technique in tailoring the porosity of BP and membranes for filtration applications.Finally, obtained BPs were tested for water filtration applications. Polystyrene beads of size ranges 0.3 µm and 0.6 µm, were chosen as model for bacteria and colloids removal, respectively. A comparison between blank BPs and modified BPs (subjected to solvent vapor for 40 minutes and prepared on specific membrane filter) was conducted. For the 0.3 µm of polystyrene beads, the blank BP showed a retention percentage of about 71% in comparison to the modified one which had a retention percentage of about 73%. For the 0.6 µm of polystyrene beads, the blank BP showed a retention percentage of about 67%, while the modified one had a percentage of about 75%. This indicates that the modified BPs possess smaller pore sizes on average than unmodified BP.

Racism began in 1619, when a Portuguese ship appeared on the coast of Virginia with more than 20 black Africans on board. It was the starting point for the spread of one of the greatest tragedies in human history. About 15 to 40 million Africans were deported to work as slaves in the American colonies, where they were subjected to various types of turtles such as: whipping, burning and rape. Later, between the 30s and 60s of the 19th century, the liberation of slaves began due to the emergence of movements calling for the abolition of slavery. Among the most prominent activists: Martin Luther King and Malcolm X. Both symbols championed the same issue of "racism", but their ways were different, as each of them has their own way of thinking and struggling. Nonetheless, the two leaders have worked in the same direction to advance black human rights. The objective of this study is to show the main differences and similarities between the two activists and also to show the effect of the two activists on people and civil rights movement.
