    This transversal case study aimed at drawing the biological profile of sensitized patients consulting for respiratory allergies at Mohamed V Military Hospital-Rabat. One hundred four patients were included in the case study, who have benefitted from specialized medical consultation and those who came to the biochemistry laboratory holding a medical check-up prescription for allergy (NFS and biochemical check-up). The biochemical analysis were made up of TMA Phadiatop(®), correct proportioning of specific IgE serum, and complete IgE. The different anamnestic and clinical parameters acting upon the sensitization to respiratory allergens have been collected through a multiple choice question survey. Statistical analysis has been performed by a SPSS software version 13.0. The Phadiatop(®) was positive at 54.8% of our patients with a masculine predominance (H/F sex-ratio = 1.4). The recurring symptoms were the rhinitis (36.8%) and the asthma (10.5%). The allergen d1 Dermatophagoides pteronyssinus was the most incriminated pneumallergens (59.6%). For 19.3% of the patients sensitized, a polysensitization (superior to three) was noted, due to dust mite, cockroaches, pollen and animals. 93.6% of the Phadiatop(®) positive patient had a hypereosinophilia (p < 0.001). The complete IgE had been prescribed to 29 patients and had been increased among 19 patients in 66% of the cases. Among the patients having a rate of elevated complete IgE, 8 (42.1%) had a negative Phadiatop(®) (p = 0.019). Our survey showed the strong prevalence of the respiratory sensitization at our population. The allergen d1 is the most incriminated. It also put in evidence the weak diagnostic value of the dosage of the complete IgE in the respiratory allergy.

  8. The Sidi Mohamed peridotites (Edough Massif, NE Algeria): Evidence for an upper mantle origin

    The Hercynian Edough massif is the easternmost crystalline massif of the Algerian coast. It consists of two tectonically superposed units composed of micaschists, gneisses, and peridotite. This study concentrates on the small and isolated Sidi Mohamed peridotite outcrop area (0.03 km2). The Sidi Mohamed peridotite is composed mainly of harzburgites (Mg-rich olivine and orthopyroxene as major minerals). The Ni (2051-2920 ppm), Cr (2368-5514 ppm) and MgO (~28-35 wt.%) whole-rock composition and the relative depletion in Nb make these harzburgites comparable to depleted peridotites related to a subduction zone. We suggest that the Sidi Mohamed ultramafic body was derived directly from the upper mantle and tectonically incorporated into the gneiss units of the Edough metamorphic core complex in a subduction environment.

    Space and Time are the prison bars of reality. Space Time Physics and Fractality is an attempt to tunnel through the rigidity of it all -- by turning everything into dust or smoke. These two ancient traditions are brought together here for the first time -- in the spirit of Democritus and Anaxagoras. Mohamed El Naschie, the sexagenarian, is the "dust dragon". The book contains papers by people who are infected by the same virus of desperately wanting to understand, and represents an incomparable breakthrough.

    We aimed to establish the ecology of the Burns Unit of the Military Teaching Hospital Mohammed V of Rabat. We present results of a retrospective study of four years (March 2006-June 2010) on all micro-organisms isolated from patient samples. During the study period, we analyzed 307 samples corresponding to isolate bacterial strains from 288 non-redundant and 5 yeasts among which 4 corresponded to Candida albicans. The bacteriological profile of the isolated stumps showed a change between 2006 and 2010. Staphylococcus aureus in 2007 and 2008 (52.3%, 33.9%) was in 3rd position in 2010 (10.5%). Acinetobacter baumannii found in 3rd position or below (3.7%, 11.6%, 15.3%), between 2006 and 2008, reached the summit in 2009 and 2010 (22.6% and 23.7%). Pseudomonas aeruginosa, strain dominant in 2006 (33.3%) maintained its second position in 2007, 2008 and 2010 (19.8%, 18.6%, 18.4%) while it was third in 2009 (14.3%). Study of the resistance in antibiotics of the main isolated bacteria showed a stability of the profile of resistance. In conclusion, an epidemiological surveillance of bacteria is necessary, in the burns unit and in the hospital, to guide better the probability antibiotic treatment.

    Retinoblastoma is the most frequent childhood intraocular tumor. The aim of our study is to evaluate the clinical features and management of extra-ocular retinoblastoma in the Mohamed VI university hospital of Marrakech. Retrospective case series, the patient's records were reviewed for patient and tumor features, ocular management, histopathological findings, and patient survival. Over a period of three years, 35 eyes were diagnosed with retinoblastoma; 12 children (16 eyes) (46%) had extra-ocular retinoblastoma. Mean age was 27 months, 60% were males. Six cases had unilateral tumor, five bilateral and one case of trilateral retinoblastoma. There was no positive family history, proptosis was the mean mode of presentation (41,6%) followed by staphyloma (25%) orbital cellulitis (25%) and hyphema(8,3%). The median lag period was 18 months. On imaging and histopathological analysis, there was extrascleral involvement in 41.6%, involvement of orbital part of optic nerve (75%), of orbital muscles (50%) and eyelids in 16.6%. the surgical treatment included according to the degree of extension enucleation (75%) or exenteration (25%) associated to chemotherapy in all cases and one case of external beam radiation. There were 2 cases of orbital recurrence, one death and no metastases at 30 months follow-up.Orbital retinoblastoma still stands as a tall challenge requiring multi-modal and multi-disciplinary approach. Although the survival has increased over the last few years, lack of access to medical facilities, lack of education about the need for early medical attention and cultural resistance to enucleation continue to contribute to an epidemic of extra ocular disease at diagnosis in the developing world.

    In 1963 Hakim Mohammed Said took a Pakistani delegation from the Society for the Promotion of Eastern Medicine on a monthlong trip to China to meet with and learn from practitioners of Traditional Chinese Medicine. This essay focuses on Said's interpretation of the history of medicine in Asia, which was inspired by his trip and informed by a broad, global understanding of how Unani medicine developed from the eighth century to the present. Said's advocacy of Eastern Medicine provides a way to think about the history of medicine and medical revitalization that is not limited by colonial, postcolonial, or nationalist assumptions and priorities.

    Smoking is a major public health problem. Doctors and paramedical staff are not excluded from this plague. Smoking ban in hospitals originated from government effort to reduce passive smoking. The objectives were to evaluate smoking habits among doctors and paramedical staff in order to implement tobacco control strategy in this study population and to refer them to the smoking-cessation counselling. We conducted a descriptive cross-sectional study of the entire staff of the Hospital University Center Mohammed VI, Marrakech based on the distribution of anonymous questionnaires. A total of 530 questionnaires were distributed, and 380 were returned, a response rate of 71.7%. The study population consisted of 58.2% women (n=221) and 41.8% men (n=159). Doctors (n=220) were the most represented occupational category (57.9%) followed by nurses (31.8%). Smokers (n=62) accounted for 16.3% of our study population; the ex-smokers (n=31) accounted for 8.1% and the non-smokers (n=287) 75.5%. The average age of smokers was 31.1 years, ranging from 22 to 56 years. The prevalence of smoking was 16.3% (n=62) of study population, of whom 32.7% (n=52) among men compared to 4.5% (n=10) among women. The average age of smoking onset was 19 years with a range from 11 to 29 years and with a mean consumption of 9 cigarettes/day. 13% (n=50) of people even smoked narguilé, 9% (n=34) consumed alcohol, and 3% (n=21) cannabis. 67.7% of smokers (n=42) were planning to quit, of whom 30.9% (n=13) in the next 3 months, 52.4% (n=22) in the next 6 months and 16, 7% (n=16) were planning to quit in the year. Several activities encouraged smoking, including night shift, coffee breaks and meals in 90.3% (n=56), 64.3% (n=40) and 61.3% (n=38) of cases respectively. This survey highlights the need to carry out awareness-raising actions to strengthen people motivation to quit smoking and help them during their withdrawal.

    The objectives of this study are to describe prescribing practices, to evaluate their appropriateness and their compliance with guidelines and to examine their influencing factors. We conducted a cross-sectional study of antibiotic prescriptions data of 105 patients in the medical and surgical Emergency Department of the Military Hospital of Instruction Mohammed V in Rabat over a period of one month. Data were collected by means of a questionnaire including demographic and anamnestic data, patient's history, allergies, specific clinical examination data, paraclinical data, detailed antibiotic prescription. Collected data were then evaluated by a referring physician, who was responsible for detecting any treatment error. Among infections requiring the prescription of antibiotics, respiratory and urinary system diseases were at the forefront, the most commonly used antibiotic families were penicillins, quinolones and cephalosporins. 74 prescriptions (70.5%) were both pertinent and compliant versus 9 prescriptions (8.6%) justified but nonpertinent and 6 prescriptions (5.7%) which were considered unjustified by the referring physician due to absence of infection. The evaluation of the existing medical practice is rarely conducted in health facilities; with this in mind, our case study aims to improve appropriate antibiotic prescribing and to optimize its compliance with guidelines.

    Hospital-acquired multidrug resistant bacteria infections are a serious public health issue causing increased morbidity, mortality and care cost. These risks underscore the need for health care institutions to maintain active panels to monitor, prevent, and manage hospital-acquired infections. The purpose of this study was to assess the epidemiology of urinary tract infection involving multidrug resistant bacteria at the Microbiology Laboratory of the Mohammed-V Military Teaching Hospital in Rabat. Study was carried out retrospectively on bacteria isolated from 10,243 urinary samples collected from January 1 to December 31, 2008. A total of 1,439 non-redundant bacteria (14.1%) meeting the criteria of urinary infection were identified. One hundred and three of the 1,439 bacteria isolated (7%) were multidrug resistant. Multidrug-resistant bacteria were more common in in-patients (63.1%). Mean patient age was 53.8 +/- 18.2 and the M/F sex ratio was 2.2. The most common multi-drug resistant bacteria were Enterobacteria producing extended spectrum bêta-lactamase (54.4% including 40.8% of Klebsiella pneumonia) and non-fermenting bacteria (45.6% including 26.2% of Pseudomonas aeruginosa. and 19.4% of Acinetobacter baumannii. These bacteria were resistant to the most commonly used antibiotics but remained highly sensitive to colistin, imipenem and amikacin.

    During the Hajj season 2014, several public health measures were applied by the Ministry of Health at Prince Mohammed International Airport in Almedinah. However, several operational defects affected the provision of preventive health services for passengers and airport workers. This study aims to evaluate the applied public health emergency system at the airport, detect any potential gaps and to provide appropriate operational solutions. This is a qualitative case study conducted at Prince Mohammed International Airport in Almedinah during the 2014 Hajj season, September 2014. Data were collected via semi-structured interviews, focus groups and policy document reviews. Interviews were conducted with the 14 individuals of the airport's decision makers and relevant health practitioners. Data were recorded via taking notes during interviews and data coding was performed to produce the main themes and subthemes of the study. The main findings of the study revealed three main defects affecting the applied public health emergency system at the airport. The main themes were mainly related to shortage in logistics related to public health emergency systems, shortage in proper documentation of policies and lack of documented protocols of communications among airport stakeholders. The study highlighted the main factors hindering the application of public health emergency measures at the airport. A Public Health Emergency Contingency Plan was proposed as a method to regulate the process of providing logistics for public health preventive services, the method of producing documented policies and methods of producing Memoranda of Understandings as communication regulators.

    We calculated the strain tensor for a sequence of earthquakes that occurred in front of Ras Mohamed, Northern Red Sea within the period from 19th November up to 31st of December 2011. The value and the direction of the strain are evaluated based on a reliable number of focal mechanism solutions. Most of the solutions indicate the dominance of normal faulting. The principal strain axis shows that the deformation is taken up mainly as an extension in the NE-SW direction with a very small crustal thinning rate. The orientation of the principal strain axes deduced from the eigenvectors is in good agreement with the main trend of the focal mechanisms of the selected events (normal type faulting).

    The purpose of this report is to present the findings of a retrospective study (2008-2009) to determine the seroprevalence of hepatitis B and C virus in blood donors at the Blood Transfusion Center of Military Teaching Hospital Mohammed V in Rabat, Morocco. Samples from 19,801 consecutive blood donors were analyzed by the immuno-enzymatic method (Enzyme Linked Immunosorbent Assay, third generation). The overall seroprevalence of HBV and HCV was 0.8% and 0.2% respectively. A total of 98 units were rejected because of elevated alanine transaminase. No case of co-infection was found. From 1991 to 2010, HBV and HCV seropositivity showed a significant declining trend. In spite of the low prevalence observed, this study confirms that the risk of transfusion transmitted infection exists and thus underlines the need to implement preventive strategies to improve blood transfusion safety.

    To evaluate the knowledge and behavior of workers at a Saudi airport regarding public health emergency measures applied during Hajj season. This study is a cross-sectional study conducted at the Prince Mohammed International Airport in Al-Madinah Al-Munawwarah, Saudi Arabia between August and September 2014. Data were collected by semi-structured questionnaires during personal interviews. Non-random purposive sampling was conducted to target workers at higher risk of acquiring infection from travellers. One hundred and eighty-six participants were recruited of whom 92.5% were males. The study participants were workers in 8 different sectors. Twenty-six percent of the participants were health workers. Non-health workers were more likely to be concerned on acquiring infection while working at the airport compared with health workers (p=0.023). The most commonly feared disease was Ebola viral disease (EBV) among 30% of health workers, and 47% of non-health workers. Approximately 47% of non-health workers reported no knowledge of the procedures implemented during public health emergencies. The proportion of participants who received public health related training among non-health workers was significantly lower compared with health workers (p less than 0.00001). More emphasis should be given to educating airport workers on the potential health threats at the airport. Specific guidelines for public health emergencies at the airport should be established and communicated with airport sectors.

Results: One hundred and eighty-six participants were recruited of whom 92.5% were males. The study participants were workers in 8 different sectors. Twenty-six percent of the participants were health workers. Non-health workers were more likely to be concerned on acquiring infection while working at the airport compared with health workers (p=0.023). The most commonly feared disease was Ebola viral disease (EBV) among 30% of health workers, and 47% of non-health workers. Approximately 47% of non-health workers reported no knowledge of the procedures implemented during public health emergencies. The proportion of participants who received public health related training among non-health workers was significantly lower compared with health workers (p<0.00001). Conclusion: More emphasis should be given to educating airport workers on the potential health threats at the airport. Specific guidelines for public health emergencies at the airport should be established and communicated with airport sectors. PMID:25828283

    This study aims to determine the prevalence of human immunodeficiency virus (HIV) infections and hepatitis B virus (HBV) and hepatitis C virus (HCV) infections among blood donors at the Blood Donor Center, Mohammed V Military Teaching Hospital between 2010 and 2012. We conducted a retrospective study among military blood donors aged 18-50 years, with a male predominance (95%). Pre-donation interview is the first selection barrier for individuals at risk. Biological screening was performed by liquid enzyme immunoassay technique using antibodies and/or antigen. Fourth generation combined HCV and HIV antigen/antibody ELISA (enzyme-linked immunosorbent assay) test was used. The Blood Donor Center and the laboratory of virology used the same technique performed in duplicate to confirm results. Out of 25661 tested samples, the prevalence rate of HBV infections was 3.97 ‰ (n = 102), the prevalence rate of HCV infections was 2.45 ‰ (n = 63) and the prevalence rate of HIV infections was 0.15 ‰ (n = 4). A single case with HBV and HCV virus co-infection (0.039 ‰) was registered, no association between HIV-HBV, HIV-HCV or HBV, HCV and HIV infections was recorded. The low seroprevalence rates of viral markers recorded in our study show improvement in preventive measures for donor selection and screening tests. The registered prevalence encourages the use of combined reagent, which is the only alternative to molecular biology in developing countries.

    A whole complement ELISA-based assay kit, primarily designed to screen for deficiencies in components of the complement system was developed during a European Union grant involving more than a dozen European scientists and a small-medium enterprise company (Wieslab, which later merged into Eurodiagnostica). The consortium was led by Prof. Mohamed R. Daha who had already guided a preceding European grant which prepared the ground for this endeavor to create a novel and sophisticated complement measurement tool. The final result of the grant was a scientific publication (Seelen et al., 2005, J. Immunol. Methods 296, 187-198) and a commercially available complement deficiency screening kit, WIESLAB(®) Complement system Screen. Thereafter, the group decided to carry on with a grant, located at Innsbruck Medical University, and supported by royalties and unrestricted educational grants from Eurodiagnostica, Malmö, entitled "Search for Applications for WIESLAB(®) Complement system Screen (SAW)" with the aim to look for further applications of this assay. During the latter project the group organized several scientific meetings aimed at evaluating the use of the assay as well as developing further branches of its platform. A look back over almost two decades reveals a great story of excellent research which was also commercially successful, fulfilling the aims of European Union grants. It is also a story of ageless friendship, only possible due to the vision and guidance of an exceptional manager: Moh Daha.

    Le cancer du sein est le premier cancer féminin en termes d'incidence et de mortalité. Au Maroc, il vient au premier rang des cancers de la femme avant celui du col utérin Il constitue un problème de santé publique. Son pronostic est étroitement lié au stade auquel le diagnostic est posé. Il s'agit d'une pathologie dont les moyens diagnostiques sont de nos jours développés, allant de la détection précoce à la mise en évidence de lésions infra-cliniques, ce qui a nettement amélioré le pronostic dans les pays développés. Ce travail que nous présentons a pour objectif d'identifier dans notre pratique quotidienne, les facteurs qui amènent les patientes à consulter à des stades tardifs. Une étude rétrospective a été menée de janvier 2012 à janvier 2013 portant sur 130 patientes porteuses d'un cancer du sein au sein du service d'onco-radiotherapie CHU Mohammed VI Marrakech. Un questionnaire a été élaboré et dument renseigné en ayant recours aux dossiers des malades. Ainsi 63,07% des patientes consultaient au-delà de six mois avec un délai moyen de consultation de 8,47 mois avec comme motif de consultation des lésions classées T4 dans 27,69%, et des tumeurs d'emblée métastatiques dans 13,84%. Les facteurs retrouvés à l'interrogatoire étaient le manque de moyens financiers 40%, l’éloignement des structures sanitaires dans 23%, les habitudes socioculturelles avec les traitements traditionnels en première intention 20%, et l'insuffisance de prise en charge thérapeutique 7%. Cependant, pris individuellement, aucune concordance significative n’était retrouvée entre ces facteurs et le long délai diagnostique. Dans notre pratique, c'est la conjonction de la triade ignorance, indigence et habitudes socioculturelles qui constituent le facteur essentiel du diagnostic tardif des cancers du sein. PMID:26327999

    Les cancers du sein bilatéraux synchrones (CSBS) sont des maladies qui se caractérisent par une importante hétérogénéité clinique et morphologique avec une fréquence entre 1,5 et 3,2%. Les femmes traitées pour un cancer du sein unilatéral sont à haut risque de développer un cancer au niveau controlatéral. Le dépistage et les progrès de l’imagerie mammaire ont permis une augmentation de découverte des CSBS. L’objectif de notre travail est d’étudier les caractéristiques épidémiologiques, cliniques, histologiques, et thérapeutiques du cancer du sein bilatéral. Il s’agit d’une étude transversale étalée sur deux années des patientes prise en charge au centre Mohammed VI pour le traitement des cancers. L’analyse statistique des résultats a été réalisée par le logiciel R. 31 patientes ont présenté un CSBS, représentant 2,4% des cas du cancer du sein dans notre Centre. L’âge moyen était 47,8 ± 8,4 ans, 22,6% utilisaient des contraceptifs oraux. Une histoire familiale de cancer du sein était observée dans 22,6% des cas. Le type histologique le plus fréquent était le carcinome canalaire infiltrant (58,1%), Le grade SBR II et III étaient fréquents (38,7%). Les récepteurs hormonaux entaient positifs, aux progestérones (38,7%) et aux œstrogènes (41,9%). Le récepteur HER2 était surexprimé dans 20,0% des cas. 29,0% des cas ont bénéficié d’une hormonothérapie et 3,2% de thérapies ciblées. Notre étude a montré que le cancer du sein bilatéral représente une proportion faible, mais avec certaines particularités cliniques, différant du cancer du sein unilatéral. PMID:28292084

    Summary L'infection est longtemps restée la principale cause de mortalité chez le brûlé grave. Ce travail a pour but d'évaluer la prescription des antibiotiques dans notre Service des Brûlés et Chirurgie Plastique, au regard du dossier d'autorisation de mise sur le marché (Résumé des caractéristiques du produit). Tous les patients sous antibiothérapie, au Service des Brûlés et Chirurgie Plastique de l'Hôpital Militaire d'Instruction Mohammed V de Rabat, Maroc, durant la période janvier 2008/mai 2009, ont été inclus. Il s'agit d'une étude rétrospective qui a analysé 41 dossiers de patients. Les antibiotiques utilisés par le service appartiennent à différentes familles. Les plus utilisés sont les bêta-lactamines (65%), glycopeptides (10,5%), aminosides (9%), quinolones (7%) et colistine (4,3%), avec 4,2% pour les autres classes d'antibiotiques (métronidazole 500 mg en perfusion, fluconazole injectable 100 mg/50 ml, rifampicine 600 mg en perfusion, sulfadiazine argentique crème, acide fusidique 2% crème, etc.); 70% des prescriptions sont non documentées. La voie injectable est prépondérante (89%). En tout, 227 ordonnances nominatives d'antibiothérapie ont été analysées: la posologie et les contre-indications ont été respectées par rapport à l'autorisation de mise sur le marché. Trois cas d'interactions médicamenteuses ont été relevés (fluconazole-rifampicine, fluconazole-Saccharomyces boulardii, amikacine-vancomycine). Ce constat montre l'importance de l'analyse pharmaceutique des prescriptions des antibiotiques dans un service utilisant des antibiotiques de la réserve hospitalière, donc actifs mais très toxiques.

    Le but de ce travail était de déterminer la prévalence du virus de l’immunodéficience humaine (VIH), du virus de l’hépatite B (VHB) et C (VHC) sur les dons du sang collectés au Centre de transfusion sanguine(CTS) de l’hôpital militaire d’instruction Mohammed V entre 2010 et 2012. Etude rétrospective menée auprès des donneurs de sang militaires âgés de 18 à 50 ans avec prédominance masculine (95%). L’entretien médical pré-don constitue la première barrière de sélection des sujets à risque. Le dépistage biologique était réalisé par technique immuno-enzymatique en milieu liquide utilisant des anticorps et/ou des antigènes. L’ELISA (enzyme linked immuno-sorbent assay) combiné de quatrième génération pour VHC et VIH a été utilisé. La confirmation a été faite en réalisant la même technique en double au CTS et au laboratoire de virologie. Dans notre série de 25661 échantillons testés, la prévalence du VHB était 3,97‰ (n=102), celle de VHC était 2,45 ‰ (n=63), celle de VIH était 0,15 ‰ (n=4). Un seul cas de coïnfection (0,039 ‰) par le VHB et VHC a été noté, aucune association entre VIH-VHB, VIH-VHC ou VHB, VHC et VIH n’a été enregistrée. Les taux faibles de séroprévalence des marqueurs viraux de notre étude montrent l’amélioration des mesures préventives en ce qui concerne la sélection des donneurs et des tests de dépistage. Cette prévalence constatée incite à maintenir l’utilisation du réactif combiné qui est la seule alternative à la biologie moléculaire pour les pays en voie de développement. PMID:28292147

Méthodes Il s'agit d'une étude descriptive transversale réalisée sur une période de 9 mois entre septembre 2010 et juin 2011, dans le service de bactériologie de l'hôpital militaire d'Instruction Mohammed V. Résultats L’étude bactériologique a été faite sur 240 téléphones mobiles dont 50% provenaient de personnels de sante. Le taux de contamination bactérienne de tous les téléphones mobiles était de 100%. Les cultures des bactéries isolées au niveau des téléphones mobiles du personnel médical étaient plus polymorphes que celles de la population témoin (p=0,028). Parmi 437 bactéries isolées: 223(51%) provenaient de téléphones de personnels de santé et 214(49%) de téléphones de la population témoin avec une différence qui n’était pas statistiquement significative(p>0,05) sauf pour les isolats de Staphylocoque à coagulase négative et Staphylococcus aureus. Les bactéries isolées étaient représentées par: Staphylocoque à coagulase (57,7%), Staphylococcus aureus (18,1%), Corynebacterium sp (18,8%), Bacillus sp (2,3%) et autres (2,2%). La différence entre la prévalence des bactéries isolées selon les services et les fonctions des personnels de santé n’était pas statistiquement significative (p>0,05). La désinfection des téléphones portables par la solution hydroalcoolique a réduit à 99,5% le nombre des colonies. Conclusion Ce travail montre que les téléphones portables pourraient jouer un rôle dans la transmission des infections nosocomiales et communautaires.

    Introduction: Development of process mapping is not easy, as, apart from identification of the key processes of the organization, mapping can hardly describe all of the interactions involved without becoming incomprehensible. In this context, the Rabat Military Hospital decided to review its process mapping to align it with the reference mapping proposed by the National Agency for Performance Support, which is designed to standardize and improve functional mapping of healthcare production systems. Methods: To assist the Military Hospital in this convergence process, this paper proposes the application of a convergence method on the current hospital process mapping, in order to guide hospital agents in the development of optimal process mapping, complying with guidelines for urbanization of information systems while remaining consistent with strategic guidelines. Results and discussion: The results obtained from application of this method to the initial hospital process mapping indicate a positive functional and organizational impact, particularly on optimization of the flow between processes.

    To review the bacteriological features of infectious spondylodiscitis and provide recommendations for the initial therapy which remains empirical in our context. Retrospective study including patients diagnosed with spondylodiscitis over a period of 4 years (2006-2009) at the Rabat Military Teaching Hospital. During the study period, we analysed 30 cases: the mean age was 49.9 years and 21 cases (70%) were male. The patients were predominantly hospitalized in neurosurgery department (15/30) followed by rheumatology department (10/30). The site of infection was lumbar in 21 cases (21/30), dorsal in 7 cases (7/30). 26 cultures were positive of which 19 (19/26) were monomicrobial. Tuberculosis (TB) was implicated in 10 cases (10/30) including 4 cases in association with common organisms (Propionibacterium acnes, Staphylococcus aureus, Staphylococcus epidermidis, Corynebacterium species). Brucella melitensis was isolated in 1 case. Infections caused by pyogenic bacteria were isolated in 15 cases of which 12 (12/15) revealed simple organisms including Gram-positive cocci in 9 cases (9/12) with 3 cases of S. aureus and Gram-negative bacilli in 3 cases (3/12) with 2 cases of P. aeruginosa. Blood cultures carried out for 16 patients were positive in 7 cases. The anatomopathologic exams carried out for 20 patients found in 6 cases epithelioid granulomata and giants cells with caseous necrosis in total concordance with TB culture. TB is the most frequent cause of spondylodiscitis in Morocco. Our study found the same frequency for non-specific and specific germs. Empirical treatment must take into account S. aureus and M. tuberculosis.

    Antiseptics have a major role against the infections and their prevention. The good management of antiseptics allows the reduction of antibiotics use and thus the emergence of resistant bacterial strains. The evaluation of the antibacterial activity of three antiseptics (povidone iodine [PVPI], iodized alcohol and alcohol 70 degrees) used at HMIMV and taken from pharmacy was based on AFNOR method NF T 72-150. The analysis of their chemical properties were done by standardized methods (manganimetry, Bunsen's method, test to determine sodium thiosulfate levels [or sodium thiosulfate test] and Guy Lussac alcoholmeter). Our results were compared with those obtained in another two university hospitals of Rabat: Hospital of Speciality and Ibn Sina. The frequencies of resistant bacterial strains were respectively 4.6%, 30.7% and 15.4% to PVPI, alcohol iodized and alcohol 70 degrees . Our results have shown that the PVPI is the best antiseptic in our hospital.

    Allergic diseases are ranked fourth considering the world health organization classification of diseases. The consequences linked to these ailments are huge for public health economics and the diagnosis is awkward due to clinical polymorphism and multifactorial aetiologies. The allergologic diagnosis is the result of weighing in clinical and biological findings. The biological assessment is made of qualitative specific and multiple-allergen serum IgE test, which once positive drives to skin test and each allergen-specific IgE level determination to conclude. Our study aims at displaying biological analysis results of incoming patients with clinical allergy conditions. We carried out a nine months retrospective study, from June 2007 to March 2008, with 200 outwards patients involved. Blood samples were collected using dry tubes and as recommended we first did screening tests for respiratory (Pharmacia Phadiatop) and food (fx 5) allergens, then for positive samples we proceeded to serum specific IgE assay (UniCap, Phadia). We also realized the total IgE assay on 46 patients using Roche Elecsys 2010 technology. 49% of patients enrolled in the study were positive to aerollergens, d1 Dermatophagoides pteronyssinus being the most incriminated (96.4%), and 2.5% to food allergens. On 13% of patients, we noticed a double sensitization to d1 and g6 (pollen of grasses). Concerning the total IgE dosage, we found 50% of patients tested with normal values, 28% of whom having a positive allergologic screening test. Further studies matching clinical data, skin tests to serum IgE assay are necessary to draw the profile of respiratory and dermatological allergies for our patients.

    The aim of the present study is to assess efficacy and efficiency of Volumetric-modulated arc therapy (VMAT) technique in treatment of nasopharyngeal cancer in our institution and to report toxicity related to this technique. Between June 2013 and January 2015, thirty-two patients with non metastatic nasopharyngeal cancer were curatively treated using VMAT Rapidarc. Dose prescription was performed using two different schedules, it consisted of either simultaneous integrated boost or simultaneous modulated accelerated radiation therapy delivering 70 Gy in 35 fractions and 69.96 in 33 fractions respectively. The choice was leaved at the discretion of the treating physician. The optimization process was performed by Eclipse software version 10.0 (Varian Medical Systems), using PRO algorithm (Progressive resolutive optimisation) version 3. Data was collected from dose-volume histograms for both planning target volumes (PTV) and organs at risk (OAR). We calculated the homogeneity index and the conformity index as well as the number of monitor units MU and the treatment delivery time. We also reported acute and late toxicity related to radiation therapy. For the PTV high risk (HR), intermediate risk (PTV IR) and low risk (LR) the D95% was 97.21 ± 1.5, 97.5 ± 3.3 and 97.10 ± 6.86 respectively. Whereas, The D5% was 104.6 ± 2.16, 103.8 ± 2.1 and 100.89 ± 7.26. The CI for PTV HR was 0.98 ± 0.02 and the HI was 0.08 ± 0.02. The mean treatment delivery time was 2.3 ± 0.2, and the mean MU number was 527.6 ± 131.4. Grade 4 toxicity was not reported in any case. Grade 3 xerostomia was observed in only 3(9.4%) patients and no patients developed grade 3 hearing loss. Our results confirmed the abilities of VMAT to provide excellent coverage of target volumes while sparing OAR especially the nervous structures and salivary glands.

    Cette étude à pour objectifs de décrire les pratiques des prescriptions, évaluer leur pertinence et leur conformité aux règles d’utilisations et étudier les facteurs susceptibles de les influencer. Il s’agit d’une étude transversale d’évaluation des prescriptions antibiotiques portant sur 105 patients réalisée au service des urgences médico-chirurgicales de l’H.M.I.Med V de Rabat sur une période d’un mois. Le recueil des données était fait à l’aide d’un questionnaire rapportant les données démographiques et anamnestiques, les antécédents, la notion d’allergie, les données spécifiques de l’examen clinique, les données para cliniques, la prescription détaillée de l’antibiotique. Les données récoltées ont été ensuite évaluées par un médecin référent, chargé d’indiquer les éventuelles erreurs de traitement. Parmi les infections ayant motivé la prescription des antibiotiques, les affections des systèmes respiratoires et urinaires étaient au premier rang, les familles d’antibiotiques les plus couramment employées sont les pénicillines, les quinolones et les céphalosporines. 74 prescriptions soit (70,5%) étaient à la fois pertinentes et conformes contre 9 prescriptions soit (8,6%) justifiées mais non pertinentes et 6 prescriptions soit (5,7%) étaient jugées injustifiées par le médecin référent par absence d’infection. Les évaluations des pratiques médicales sont rarement menées dans les établissements de santé; c’est dans ce cadre que nous avons voulu nous inscrire en produisant cette étude afin d’améliorer la pertinence de nos prescriptions antibiotiques et d’optimiser leur conformité aux différentes recommandations.

    The distinction between diabetic nephropathy lesions and non-diabetic renal lesions is not always obvious and is often based on renal biopsy. This study evaluated the prevalence and predictors of nondiabetic renal disease in people with type 2 diabetes. The study was conducted between January 2008 and October 2010 in the nephrology department of the military hospital in Rabat. The study included 16 patients with type 2 diabetes in whom renal biopsy was indicated. Non-diabetic renal disease was found in 6 of the patients (37.5%); IgA nephropathy was the most frequent non-diabetic renal disease (half of non-diabetic renal diseases). Hypertension was significantly less frequent in the non-diabetic renal disease group than the diabetic nephropathy group (16.7% versus 80.0%, P = 0024), duration of diabetes was a shorter (4.5 versus 15.5 years, P = 0.022) and diabetic retinopathy was absent (100% versus 40%, P = 0.026). There were no statistically significant differences between the 2 groups in relation to age, sex, creatinine level, 24-hour proteinuria, nephrotic syndrome and microscopic haematuria.

    The goal of this paper is to discuss how to ameliorate the management of penetrating cardiac injuries in general surgery department. An algorithm for the initial assessment of penetrating injuries in cardiac box, based on our own experience, is presented. This was a retrospective study of 19 patients undergoing thoracotomy for penetrating cardiac injuries, managed in the department of general surgery of Nabeul-Tunisia, between 1994 and 2010. The mean age of patients was 25 years old. Sex ratio was 8,5. All patients had cardiac injury resulting from stab wounds inside of the pericardium. 42% of them were critically unstable, 21% had cardiac tamponnade. All these patients were quickly transferred to the operating room without any other investigations. 37% of patients were hemodynamically stable and underwent additional investigations. The management of penetrating cardiac injuries is possible in a general surgery department, but it requires a rapid prehospital transfer, a yet thorough physical examination along with efficient surgical management, all done in minimal time.

    In spite of the direct referral system and family-centered model of primary oral health care linking medical and dental care providers, most HIV-positive patients at the Columbia Presbyterian Medical Center received only emergency and episodic dental care between 1993 and 1998. To improve access to dental care for HIV/AIDS patients, a mobile program, called WE CARE, was developed and colocated in community-based organizations serving HIV-infected people. WE CARE provided preventive, early intervention, and comprehensive oral health services to minorities, low-income women and children, homeless youths, gays and lesbians, transgender individuals, and victims of past abuse. More efforts to colocate dental services with HIV/AIDS care at community-based organizations are urgently needed, however. PMID:11499099

    The aim of this study was to investigate the molecular epidemiology and the genetic support of carbapenem-resistant Enterobacteriaceae and Acinetobacter spp. isolates collected in the University Hospital of Ouargla, southern Algeria. A total of 99 Gram-negative bacteria (GNB) were collected from stool samples of colonised patients and from inanimate surfaces in the hospital environment between December 2014 and August 2015. Selected Enterobacteriaceae and Acinetobacter spp. isolates with reduced susceptibility to carbapenems were subjected to phenotypic study, including antibiotic susceptibility testing according to CA-SFM-EUCAST 2015 guidelines and modified Carba NP test. Genes encoding carbapenemases, extended-spectrum β-lactamases (ESBLs) and AmpC β-lactamases were screened by PCR and sequencing. Clonal relatedness was determined by multilocus sequencing typing (MLST). Of the 99 GNB isolates, 10 (10.1%) showed reduced susceptibility to carbapenems were studied further, including 7 Acinetobacter baumannii, 1 Acinetobacter nosocomialis, 1 Escherichia coli and 1 Klebsiella pneumoniae. PCR and sequencing showed that four A. baumannii isolates and the single A. nosocomialis isolate harboured blaNDM-1. In addition, blaOXA-23 was observed in three A. baumannii isolates, and blaOXA-48 was detected in the two Enterobacteriaceae isolates. MLST assigned the K. pneumoniae to ST999 and the E. coli to ST38. The seven A. baumannii isolates belonged to ST85 and ST2. This study describes the epidemiology of carbapenemases produced by Enterobacteriaceae and Acinetobacter spp. in southern Algeria and reports the first description of metallo-β-lactamase NDM-1-producing A. nosocomialis in Algeria.

    La kératoplastie transfixiante est l'une des plus fréquentes des greffes de tissus et transplantations d'organes. Le but de notre travail est de rapporter notre expérience en matière de greffe de cornée. C'est une étude prospective de 195 patients ayant bénéficié d'une greffe de cornée sur une période allant d'aout 2009 à Août 2015. Le recul moyen est de 21 mois. Les indications de la greffe étaient le kératocône 33.8%, les séquelles de traumatisme 10.7%, la kératopathie bulleuse 19.5%, les dystrophies héréditaires 10.7%, et les kératites herpétiques 9.2%. L'acuité visuelle initiale était inférieure à 1/10 dans 90% des cas. Nous avons observé une réaction de rejet dans 19 yeux dont 14 étaient récupérables, 33 hypertonies oculaires, 20cataracte, et 2 décollements descmetiques. La greffe de cornée apparaît comme une intervention donnant de bons résultats anatomiques et fonctionnels. Les résultats ne doivent pas occulter une surveillance post opératoire étroite et régulière pour dépister à temps d’éventuelles complications, en particulier le rejet de greffe. PMID:27303575

    Objective. To study the sensitivity level of extended spectrum beta-lactamase-producing Enterobacteriaceae to Carbapenems (Imipenem, Ertapenem) marketed in Morocco and discusses the place of Ertapenem in the treatment of extended spectrum-beta-lactamase-producing. Materials and Methods. A retrospective study of 110 extended spectrum beta-lactamase-producing Enterobacteriaceae. Isolates obtained from blood cultures, superficial and deep pus, and catheters were conducted. The minimum inhibitory concentrations of Imipenem and Ertapenem were done by the E-test. The modified Hodge test was conducted for resistant or intermediate strains. Results. 99.1% of isolates were susceptible to Imipenem. For Ertapenem, 4 were resistant and 4 intermediate. The modified Hodge test was positive for all 08 isolates. A minimum inhibitory concentration comparison of K. pneumoniae, E. cloacae, and E. coli for Imipenem has noted a significant difference between E. cloacae on one hand and E. coli, K. pneumoniae on the other hand (P < 0.01). No significant difference was noted for minimum inhibitory concentration of Ertapenem. Conclusion. Our results confirm in vitro effectiveness of Ertapenem against extended spectrum beta-lactamase-producing Enterobacteriaceae as reported elsewhere. However, the emergence of resistance to Carbapenems revealed by production of carbapenemases in this study confirmed a necessary bacteriological documented infection before using Ertapenem.

    Le tabagisme est un problème majeur de santé publique. Le personnel médical et paramédical n'est pas épargné par ce fléau. L'interdiction de fumer à l'hôpital est née d'une volonté gouvernementale de réduire le tabagisme passif. L'objectif de cette étude était d'évaluer les habitudes tabagiques chez le personnel soignant médical et paramédical, afin d'élaborer une stratégie de lutte contre le tabagisme au sein de cette population, et de les adresser éventuellement à la consultation d'aide au sevrage tabagique. L'étude transversale descriptive concernant l'ensemble du personnel soignant du CHU de Marrakech en se basant sur la distribution des questionnaires anonymes. Nous avons distribué 530 questionnaires dont 380 ont été récupérés, soit un taux de réponse de 71,7%. La population d'étude était constituée de 58,2% de femmes (n= 221) et de 41,8% d'hommes (n=159). Le personnel médical (n=220) était la catégorie professionnelle la plus représentée (57,9%) suivie des infirmiers (31,8%). Les fumeurs (n = 62) représentaient 16,3% de notre population d'étude; les ex-fumeurs (n=31) 8,1% et les non-fumeurs (n= 287) 75,5%. La moyenne d'âge des fumeurs était de 31,1 ans avec des extrêmes de 22 à 56 ans. La prévalence du tabagisme était de 16,3% (n=62) de la population d'étude dont 32,7% (n=52) chez les hommes contre 4,5 % (n=10) chez les femmes. L'âge moyen de début du tabagisme était de 19 ans avec des extrêmes de 11 à 29 ans avec une consommation moyenne de 9 cigarettes/jour. 13% (n=50) des personnes fumaient aussi le narguilé, 9% (n=34) consommaient de l'alcool et 3% (n=21) des personnes consommaient du Cannabis. 67,7% des fumeurs (n=42) se projetaient d'arrêter de fumer, dont 30,9% (n=13) dans les 3 prochains mois, 52,4% (n=22) dans les prochains 6mois et 16,7% (n=16) se projetaient d'arrêter dans l'année. Plusieurs activités incitaient les fumeurs à fumer davantage dont la garde, la pause-café, et les repas dans respectivement 90,3% (n=56), 64,3% (n=40) et 61,3% (n=38) des cas. A la suite de cette enquête, une réflexion doit être menée sur la nécessité de mener des actions de sensibilisation pour renforcer la motivation de ceux qui désirent arrêter et les aider dans leur démarche de sevrage.

    Les infections mycosiques du pied constituent un motif fréquent de consultation chez les diabétiques, le diabète constituant à la fois un facteur favorisant et aggravant les lésions cutanéomuqueuses. L'objectif de ce travail était d'identifier la flore mycologique locale responsable des lésions du pied chez le diabétique et déterminer les facteurs favorisant la survenue de mycoses. Il s'agissait d'une étude transversale intéressant des diabétiques suivis en consultation; un prélèvement mycologique, avec examen direct et culture, a été réalisé devant toute suspicion clinique de lésion mycosique. Quatre-vingt-deux patients ont été inclus. L'hémoglobine glycosylée moyenne a été de9,2% ± 2,23. Un intertrigo inter orteil a été noté dans 90,2% des cas; l'examen mycologique était positif dans 64,8% des cas, avec 18 cas de Trichophyton rubrum et 11 cas de Candida albicans. Une atteinte unguéale a été suspectée chez 65,9% patients; la culture a mis en évidence un Trichosporon pathogène chez sept patients, un Candida albicansdans six cas, un Trichophyton rubrum dans quatre cas, avec trois cas de Trichophyton mentagrophytes et deux cas de Scytalidium dimidiatum. L’étude analytique, après confirmation mycologique, en fonction des principales caractéristiques des patients a montré que l'atteinte mycosique du pied est significativement corrélée au déséquilibre glycémique. Ce travail a montré la prédominance du Trichophyton rubrum dans les lésions d'intertrigo inter orteil et du Trichosporon dans les onychomycoses, avec une prédominance globale plus globale plus élevée du TR.

    Nine species of Siganus (Perciformes: Siganidae) were examined for dactylogyrids (Monogenoidea) from the Red Sea, Egypt; the Great Barrier Reef, Australia; and the South China Sea, China. Species of Tetrancistrum were found on siganids from all 3 localities; Pseudohaliotrema spp. were restricted to siganids from the Great Barrier Reef; and species representing Glyphidohaptor n. gen. were found on siganids from the Red Sea and Great Barrier Reef. Siganus argenteus from the Red Sea and Siganus vulpinus from the Great Barrier Reef were negative for dactylogyrid parasites. Glyphidohaptor n. gen. is proposed for 3 species (2 species new to science) and the new species are described: Glyphidohaptor phractophallus n. sp. from Siganus fuscescens from the Great Barrier Reef; Glyphidohaptor sigani n. sp. from Siganus doliatus (type host), Siganus punctatus, Siganus corallinus, and Siganus lineatus from the Great Barrier Reef; and Glyphidohaptor plectocirra (Paperna, 1972) n. comb.

    To identify genomic markers that are reliable in predicting lymph node metastases in clinical stage 1 non-seminomatous germ cell tumors (NSGCTs). Comparative genomic array technology was used to identify regions of genomic amplification or deletion in clinical stage 1 NSGCTs. Twelve stage 1 mixed germ cell testicular tumors were analyzed, which were obtained from 8 patients who had no evidence of nodal metastasis when retroperitoneal lymph node dissection (RPLND) had been performed (i.e., were RPLND negative) and 4 patients who had nodal metastases (i.e., were RPLND positive). Differences between the genomic alterations associated with the two classes of tumors were identified. Genomic alterations previously reported in other subtypes of testicular tumors were observed in both metastatic and nonmetastatic cases. Statistically suggestive differences in mean copy number of the Y chromosome were found between metastatic and nonmetastatic cases (P = 0.0142). This finding suggests the presence of chromosome Y deletions to be a potential genetic marker for prediction of mixed germ cell tumor progression. This is a first step toward identifying chromosomal markers of progression in testicular cancer in clinical stage 1 mixed germ cell NSGCT. Copyright © 2013. Published by Elsevier Inc.

    2014-02-11

    To evaluate knowledge, attitude and practices (KAP) of physicians regarding the management of medications in Ramadan we used a self-administered questionnaire on a target sample of 381 physicians at Jordan University Hospital, King Abdulla University Hospital and a number of private clinics in Amman, during September and October of 2008. A total of 297 questionnaires were returned. Physicians' KAP about management of medications in Ramadan was generally insufficient.

    Objective: The aim of the present study was to evaluate the use of off-label antibiotics in neonatal intensive care units (NICUs) and paediatric wards in Jordan. Methods: Data of patients admitted to the neonatal intensive care units and paediatric wards in King Abdulla University Hospital were collected over an 8-week survey between May and July 2012. Data collected in this study included patients’ age, weight, medical history, diagnosis and the details of antibiotics prescribed to each patient. Results: The study involved a total of 250 children (80 admitted to the NICU and 170 admitted to the wards). A total of 598 antibiotic prescriptions were issued for these patients (244 in NICUs and 354 in paediatricwards). The results of the present study show that off-label antibiotic prescribing to paediatric patients is very common. Off-label antibiotic prescribing to paediatric patients is related mostly to doses and indications, and rarely to age. The majority of admitted patients received at least one off-label antibiotic during their hospital stay. Conclusion: This study reveals the high prevalence of off-label use of antibiotic among paediatric children in Jordan. There is a serious need for robust and continuous educational programs to improve the awareness of paediatricians of guidelines surrounding the use of antibiotics in paediatric patients. Furthermore, true collaboration between paediatricians and clinical pharmacists towards safe and effective antibiotic prescribing in paediatric patients is crucial. PMID:27785160

  14. Efficient Algorithms for Handling Nondeterministic Automata

    NASA Astrophysics Data System (ADS)

    Vojnar, Tomáš

    Finite (word, tree, or omega) automata play an important role in different areas of computer science, including, for instance, formal verification. Often, deterministic automata are used for which traditional algorithms for important operations such as minimisation and inclusion checking are available. However, the use of deterministic automata implies a need to determinise nondeterministic automata that often arise during various computations even when the computations start with deterministic automata. Unfortunately, determinisation is a very expensive step since deterministic automata may be exponentially bigger than the original nondeterministic automata. That is why, it appears advantageous to avoid determinisation and work directly with nondeterministic automata. This, however, brings a need to be able to implement operations traditionally done on deterministic automata on nondeterministic automata instead. In particular, this is the case of inclusion checking and minimisation (or rather reduction of the size of automata). In the talk, we review several recently proposed techniques for inclusion checking on nondeterministic finite word and tree automata as well as Büchi automata. These techniques are based on using the so called antichains, possibly combined with a use of suitable simulation relations (and, in the case of Büchi automata, the so called Ramsey-based or rank-based approaches). Further, we discuss techniques for reducing the size of nondeterministic word and tree automata using quotienting based on the recently proposed notion of mediated equivalences. The talk is based on several common works with Parosh Aziz Abdulla, Ahmed Bouajjani, Yu-Fang Chen, Peter Habermehl, Lisa Kaati, Richard Mayr, Tayssir Touili, Lorenzo Clemente, Lukáš Holík, and Chih-Duo Hong.

  15. The regulation of cytochrome P450 2E1 during LPS-induced inflammation in the rat

    It is well known that inflammatory and infectious conditions differentially regulate cytochrome P450 (P450)-mediated drug metabolism in the liver. We have previously outlined a potential pathway for the downregulation in hepatic cytochrome P450 following LPS-mediated inflammation in the CNS (Abdulla, D., Goralski, K.B., Garcia Del Busto Cano, E., Renton, K.W., 2005. The signal transduction pathways involved in hepatic cytochrome P450 regulation in the rat during an LPS-induced model of CNS inflammation. Drug Metab. Dispos). The purpose of this study was to outline the effects of LPS-induced peripheral and central nervous system inflammation on hepatic cytochrome P450 2E1 (CYP2E1) in vivo, an enzyme that plays an important role in various physiological and pathological states. We report an increase in hepatic mRNA expression of CYP2E1 that occurred as early as 2-3 h following either the intraperitoneal (i.p.) injection of 5 mg/kg LPS or i.c.v. administration of 25 {mu}g of LPS. This increase in CYP2E1 mRNA expression was sustained for 24 h. In sharp contrast to the increase in hepatic CYP2E1 mRNA, we observed a significant reduction in the catalytic activity of this enzyme 24 h following either the i.c.v. or i.p. administration of LPS. Cycloheximide or actinomycin-D did not change the LPS-mediated downregulation in hepatic CYP2E1 catalytic activity. Our results support the idea that LPS acts at two different levels to regulate hepatic CYP2E1: a transcriptional level to increase CYP2E1 mRNA expression and a post-transcriptional level to regulate CYP2E1 protein and activity.

    Researchers are questioning the method used to monitor the quality of a scientific journal belonging to the Dutch publishing giant Elsevier after its editor-in-chief was found to be publishing almost all his papers in the journal. Mohamed El Naschie, editor-in-chief of Chaos, Solitons and Fractals (CSF), published 58 papers last year, of which 53 are in the journal itself. Elsevier will announce his retirement from CSF, which had been planned since mid-2007, in the first issue of the journal this year. The company also plans to revamp the journal's submission process.

    For centuries, romantics have praised and historians and scientists debated the mystery of Joan of Arc's exceptional achievements. How could an uneducated farmer's daughter, raised in harsh isolation in a remote village in medieval France, have found the strength and resolution to alter the course of history? Hypotheses have ranged from miraculous intervention to creative psychopathy. We suggest, based on her own words and the contemporary descriptions of observers, that the source of her visions and convictions was in part ecstatic epileptic auras and that she joins the host of creative religious thinkers suspected or known to have epilepsy, from St. Paul and Mohammed to Dostoevsky, who have changed western civilization.

    The violent true believer is an individual committed to an ideology or belief system which advances homicide and suicide as a legitimate means to further a particular goal. The author explores useful sources of evidence for an indirect personality assessment of such individuals. He illustrates both idiographic and nomothetic approaches to indirect personality assessment through comparative analyses of Timothy McVeigh, an American who bombed the federal building in Oklahoma City in 1995, and Mohamed Atta, an Egyptian who led the airplane attacks against the World Trade Center and the Pentagon in 2001. The risks of indirect personality assessment and ethical concerns are identified.

    Global nursing shortages have necessitated closer scrutiny of recruitment and retention initiatives of nurses both locally and internationally. For many decades the nursing workforce of Saudi Arabia has relied on international expatriates to be the backbone of the industry. In recent years however, Saudi women have been recruited into nursing preparation courses conducted at degree level. The many twists and turns of providing a local Saudi Arabian nursing workforce has paralleled Saudi's own history and this paper follows that journey. Our research has enabled us to provide some insights into nursing pre and post the enlightenment that accompanied the Prophet Mohammed's influence. We emphasize the influences of women leaders who emerged in Mohammed's time and bring lasting authority to the development of nursing in Saudi Arabia. The cultural issues that bind women in this society are explicated and related to recruitment and retention issues in nursing. Education matters, both past and present, are highlighted emphasizing the gains that nursing as a distinct occupation has made. Finally the paper concludes with a summation of contemporary achievements in Saudi Arabia moving nursing towards the much needed professional status and parity with other careers in health care.

    We present the observed results of time variations of brightness and polarization with the rotation of an asteroid for 3 Juno (S-type main belt asteroid) and 216 Kleopatra (M-type main belt asteroid). Taking into account an empirical relation between the polarization and the albedo of an asteroid in Lupishko and Mohamed (1996, Icarus 119, 209), we converted our polarimetric data to the time variation of albedo with the rotation of an asteroid. It is found that the inhomogeneous distribution of albedo exists on the surface of both asteroids. Resulting modulation of albedo for 3 Juno and 216 Kleopatra shows a variation between 0.14-0.20 and 0.08-0.14, respectively.

    ABSTRACT Mucocele, a common benign cystic lesion of minor salivary gland and associated ducts develops following extravasation or retention of mucous material in the subepithelial tissue. Occurrence of mucocele of tongue is considered less frequent when compared to a higher incidence of mucocele in the lower lip of young patients. Different modalities of treatment, such as conventional surgical excision followed by newer techniques like cryosurgery, electrocautery have been proposed to completely remove the lesion and reduce the chances of recurrence. Herewith, we report a novel treatment technique using alginate impression material to aid in complete excision of mucocele of glands of Blandin-Nuhn.

    Both ab initio molecular dynamics simulations based on the Born-Oppenheimer approach calculations and a quantum theoretical model are used in order to study the IR spectrum of the acetic acid dimer in the gas phase. The theoretical model is taking into account the strong anharmonic coupling, Davydov coupling, multiple Fermi resonances between the first harmonics of some bending modes and the first excited state of the symmetric combination of the two vO-H modes and the quantum direct and indirect relaxation. The IR spectra obtained from DFT-based molecular dynamics is compared with our theoretical lineshape and with experiment. Note that in a previous work we have shown that our approach reproduces satisfactorily the main futures of the IR experimental lineshapes of the acetic acid dimer [Mohamed el Amine Benmalti, Paul Blaise, H. T. Flakus, Olivier Henri-Rousseau, Chem Phys, 320(2006) 267-274.].

    How is it that the name of a brilliant 18th century scientist and philosopher, many of whose exceptional achievements were often advanced for his time, is almost never mentioned in the annals of science? And how did it happen that a man very deeply dedicated to the advancement of science experienced a vision that completely altered the course of his life? We suggest, based on his extensive self-analytical writings, that the source of his spiritual experiences was temporal lobe epilepsy (TLE) and that he is among the group of creative religious thinkers also suspected or known to have had epilepsy, from St. Paul and Mohammed to Dostoevsky, who have changed Western civilization.

    Selective mapping of surface charge carrier dynamics of InGaN nanowires before and after surface passivation with octadecylthiol (ODT) is reported by O. F. Mohammed and co-workers on page 2313, using scanning ultrafast electron microscopy. In a typical experiment, the 343 nm output of the laser beam is used to excite the microscope tip to generate pulsed electrons for probing, and the 515 nm output is used as a clocking excitation pulse to initiate dynamics. Time-resolved images demonstrate clearly that carrier recombination is significantly slowed after ODT treatment, which supports the efficient removal of surface trap states. © 2016 WILEY-VCH Verlag GmbH & Co.

    In this paper we calculate the Raman spectra of different double-walled carbon nanotubes (DWCNTs) by using the spectral moments method. Using a convenient Lennard-Jones expression of the van der Waals intermolecular interaction between the inner and outer tubes, the optimized structures of DWCNT are derived. We found that the C-C bond length in DWCNT is depending on the metallic (M) or semiconducting (Sc) character of the inner and outer nanotubes. We show that the radial breathing-like modes (RBLM) of DWCNT are characterized by concerted inner and outer wall motions. Comparison with Raman spectra measurements is given.

  15. Low Decision Space Means No Decentralization in Fiji

    PubMed Central

    2016-01-01

    Mohammed, North, and Ashton find that decentralization in Fiji shifted health-sector workloads from tertiary hospitals to peripheral health centres, but with little transfer of administrative authority from the centre. Decision-making in five functional areas analysed remains highly centralized. They surmise that the benefits of decentralization in terms of services and outcomes will be limited. This paper invokes Faguet’s (2012) model of local government responsiveness and accountability to explain why this is so – not only for Fiji, but in any country that decentralizes workloads but not the decision space of local governments. A competitive dynamic between economic and civic actors that interact to generate an open, competitive politics, which in turn produces accountable, responsive government can only occur where real power and resources have been devolved to local governments. Where local decision space is lacking, by contrast, decentralization is bound to fail because it has not really happened in the first place. PMID:27801361

    2006-06-01

    The classical view of our external world is revised and its tacit a priori assumptions are confronted with consequences from Mohammed S. El Naschie's E-infinity theory. The far-reaching investigations of El Naschie have demonstrated the necessity of a new unconventional thinking in physics. First we motivate the a priori assumptions of classical mechanics with the requirements of the mathematical formalisms. We explain the difficulties to construct models for a reality which shows the phenomenon of contextualism, like for example quantum mechanics. In a second step we use the principles of Husserl's phenomenology to deduce a toy world from a contextual understanding of empirical data. In such a toy world one can illustrate the fundamental phenomena from quantum mechanics and ideas from E-infinity theory. We will use this toy world to demonstrate that the classical a priori assumptions are not necessary and that alternative ways of thinking are possible in physics.

    The present study aims to use the concept of entropy generation in order to study numerically the flow and the interaction of multiple jets. Several configurations of a single jet surrounded by equidistant 3, 5, 7 and 9 circumferential jets have been studied. The turbulent incompressible Navier-Stokes equations have been solved numerically using the commercial computational fluid dynamics code Fluent. The standard k-ɛ model has been selected to assess the eddy viscosity. The domain has been reduced to a quarter of the geometry due to symmetry. Results for axial and radial velocities have been compared with experimental measurements from the literature. Furthermore, additional results involving entropy generation rate have been presented and discussed.

    This is mainly an experimental contribution about defect detection based on the flash method generally used to characterize the thermal diffusivity of the material. The temperature rise on the rear face of the sample generated by the flash provides important information. We have conceived and realized a contact thermal sensor consisting of forty-nine type K thermocouples distributed over the rear face of the sample to be tested. The thermocouples responses, as measured by several thermograms, are given in several measuring points distributed over the entire bottom surface of the sample. Analysis of the experimental results shows that the temperature rise provide important information to establish a thermal system for defect detection in homogeneous materials containing heterogeneities.

    Introduction Primary rectal lymphoma is a rare disease. In this paper we present an unusual case of primary rectal lymphoma which was managed with chemotherapy and discussed by a thorough review of the related literature. Cases presentation An 85-years-male patient was diagnosed in Sidi Mohammed Ben Abdellah Hospital as having diffuse large B-cell lymphoma of the rectum at a bulky stage two. This patient was managed successfully with 8 treatment cycles of Cyclophosphamide 750 mg/m2 at day 1 of each cycle, Doxorubicin (50 mg/m2 in the first 4 cycles and 25 mg/m2 in the subsequent cycles) at day 1 of each cycle, Vincristine 1.4 mg/m2 at day 1 of each cycle, and prednisone 50 mg/m2 at day 1 to 5 of each cycle. Conclusion The optimal treatment of primary rectal lymphoma needs more research studying to be achieved. PMID:20062547

Some of these successes include practical measures to eliminate violence against women; introduction of a quota for women in public sector employment; and launching of the Health and Population Sector Program to provide a one-stop, full range of essential reproductive health, family planning and child health services through an integrated delivery mechanism. Moreover, the Minister informed the Forum participants that their success is attributable to many factors which include support from the government, from non-governmental organizations, civil society, mass media, religious and other community leaders, intersectoral collaboration, microcredit and income-generation activities.

    Amounting scientific evidences have revealed the antitumor, antimetastatic, antiangiogenic, antiproliferative, chemopreventive and neo-adjuvant efficacy of Prophetic Medicine in various in vitro, in vivo and clinical cancer models. Prophetic Medicine includes plants, dietary materials or spices that were used as remedy recipes and nutrition by the great Prophet Mohammed (peace be upon him) to treat various ailments. Prophetic medicine is the total authentic Hadith narrated by the Prophet (PBUH) in relation to medicine, whether Qur'anic verses or honourable Prophetic Hadith. The ability of functional foods from Prophetic Medicine to modulate various signalling pathways and multidrug resistance conferring proteins with low side-effects exemplify their great potential as neo-adjuvants and/or chemotherapeutics. The present review aims to provide the collective in vitro, in vivo, clinical and epidemiology information of Prophetic Medicines, and their bioactive constituents and molecular mechanisms as potential functional foods for the management of cancer.

    The phenomenon of miracle has been present in each time period and each civilization, and what has changed was not its definition but its content. Gautama Buddha, Apostle Paul, Mohammed, Church fathers from Origen and Augustine of Hippo to Gregory the Great and Thomas Aquinas were all studying miracles and trying to find out the rules and systematization for them. The present paper explores the intriguing differences (e.g., the proportions of miracle types) and similarities (e.g. saintly "specialization") between some Eastern and Western miracle accounts, analyzing the possible underlying reasons. As a case study, the collection of miracles performed by St. Thecla (Basil of Seleukia, 5th c. AD) has been used. The major conclusion of the paper is that miracle accounts quite consequently reflect cultural differences between East and West.

    At the University of Akron, Dr. Loren Siebert, Dr. Richard Klosterman, and their graduate research assistants (Jung-Wook Kim, Mohammed Hoque, Aziza Parveen, and Ben Stabler) worked on the integration of remote sensing and GIs-based planning support systems. The primary goal of the project was to develop methods that use remote sensing land cover mapping and GIs-based modeling to monitor and project urban growth and farmland loss in northeast Ohio. Another research goal has been to use only GIS data that are accessible via the World Wide Web, to determine whether Ohio's small counties and townships that do not currently have parcel-level GIS systems can apply these techniques. The project was jointly funded by NASA and USGS OhioView grants during the 2000-2001 academic year; the work is now being continued under a USGS grant.

    The oral public health program for patients with diabetes was initiated by Saudi Arabia Ministry of Health (MoH) based on international quality standard to control the severity of oral disease in patients with diabetes through improving the accessibility of patients to dental clinics in primary health care centers (PHCC). This program intends to deliver oral health care (OHC) for each patient with diabetes at least one visit every six months. However, we found that more than 90% of patients with diabetes that visited prince Mohammed bin Saud PHCC in Riyadh do not get their regular dental check up every six months. We developed a quality improvement project (QIP) using the quality improvement model to activate MoH oral health program for patients with diabetes visiting prince Mohamed bin Saud PHCC. The aim of our QIP was to increase number of patients with diabetes receiving their regular oral health check up during the PHC visit. The quality team tested two simple improvement ideas. The first idea was having the dentist signature on appointment request. The testing of the first idea led to the second idea, that both physician and dentist should sign the referral form. After running several PDSA cycles to test these interventions ideas, we found the number of patients with diabetes seen in dental clinic had increased dramatically compared with the baseline assessment. We conclude that the idea of signing the referral form by both physician and dentist is a practical and simple strategy to be executed and has a direct impact on the patient clinical flow between clinics.

    Summary La brûlure est l’une des lésions les plus fréquemment rencontrées lors de catastrophes naturelles ou lors de catastrophes d’origine humaine (incendies de lieux publics d’origine accidentelle, ou en temps de guerre ou encore lors d’attentats terroristes). La prise en charge et le triage de brûlés en nombre reste un problème difficile; ceci souligne la nécessité d’une réflexion et de prévisions de ces crises en insistant sur la formation des médecins et des soignants. Les défis à relever sont multiples: les soins aux brûlés requièrent un nombre important de personnel qualifié; les évacuations doivent être planifiées en fonction de la gravité de la brûlure et des lésions associées; les stocks et lots de dotation (en particulier en topiques anti-infectieux et en cristalloïdes) doivent être suffisants et adéquats. Les services hospitaliers de l’Hôpital Militaire d’Instruction Mohammed V de Rabat doivent pouvoir être rapidement adaptés pour accueillir et surtout isoler ces patients. L’hypothèse d’une catastrophe par incendie avec afflux massif de brûlés à l’hôpital militaire d’instruction Mohammed V de Rabat ne doit laisser place à aucune improvisation. PMID:23467075

    Currently, only 31 nereidid species are known from the Persian Gulf and Gulf of Oman. The present study was carried out in order to investigate the poorly known diversity of nereidid polychaetes from seas of the southern coasts of Iran. Specimens were collected from 23 locations along the intertidal zones of the two water bodies. Among the 26 species found: two are new, and are described here, including Simplisetia qeshmensis sp. nov. and Neanthes biparagnatha sp. nov.; 11 are new geographical records. Neanthes biparagnatha sp. nov. is most similar to N. deplanata (Mohammed, 1971), which is also found in the Persian Gulf, but can be most easily distinguished from it by the presence of bars in addition to cones in Area IV of the pharynx. Simplisetia qeshmensis sp. nov. may be distinguished from its closest congener, S. erythraeensis (Fauvel, 1918), also reported from the Persian Gulf, by having a greater number of paragnaths in Area I of the pharynx, an additional type of chaeta (homogomph spinigers) in the ventral neuropodial fascicle and having a reduced notopodial lobe in posterior chaetigers. The list of new records includes: one species from both areas, Neanthes glandicincta (Southern, 1921); eight species from the Persian Gulf, Leonnates decipiens Fauvel, 1929, Neanthes acuminata (Ehlers, 1868), Neanthes sp., Neanthes sp. cf. N. acuminata, Nereis sp. cf. N. pelagica Linnaeus, 1758, Perinereis cultrifera (Grube, 1840) species complex., Pseudonereis trimaculata (Horst, 1924), Pseudonereis sp. cf. P. variegata (Grube, 1857) and two from the Gulf of Oman, Leonnates persicus Wesenberg-Lund, 1949 and Perinereis kuwaitensis Mohammed, 1970. The present study brings to 40 the number of nereidid species currently known from the Persian Gulf and Gulf of Oman. A taxonomic key to nereidid species from the intertidal zones of the Persian Gulf and Gulf of Oman is presented to facilitate future investigations.

    humification. The less humified samples contain relatively more components having a relationship to lignin. The more humified samples are composed of relatively more molecular formulas in the CCAM and condensed aromatic regions and also contain relatively more carboxylated molecular formulas than the less humified samples. To explain the molecular formulas observed we propose a humification process that involves photo- or microbially-generated reactive oxygen species in soils which are responsible for transforming the materials supplied to soil as fresh organic matter, mainly lignin, to the molecules observed in ESI-FTICR-MS data. When plotted on the van Krevelen diagram, the H/C and O/C ratios of molecular formulas from humic acids predictably plot in the same regions as the newly produced formulas discovered by Chen, et al. (2014) when natural organic matter was photoirradiated or when lignin-derived humics were subjected to Fenton chemistry (Waggoner et al., 2015).

DO events are manifested in marine and continental records in the circum-North Atlantic region and throughout the globe. Several studies suggest a crucial role of the Nordic seas in regulating the climate during the last glacial period. Previous studies from the Nordic seas revealed low benthic δ18O values during stadials and high values during interstadials. The causes of the depletions in benthic 18O during stadials are highly debated. Sinking of isotope depleted-brines formed due to sea ice production has previously been proposed. Another explanation has indicated warming of the intermediate water in the Nordic seas based on the finding of warm water benthic foraminiferal species during stadials. Here we present the first benthic foraminiferal Mg/Ca-based bottom water temperature (BWT) record from the Nordic seas that, along with other proxies, aims to resolve the hydrographic changes at intermediate water depth on DO timescale during the last 65 kyr. The results show pronounced and gradual BWT increases during all cold stadials followed by an abrupt drop to modern-like BWT at interstadials onsets. The increase in BWT, caused by the subsurface inflow of warm Atlantic intermediate water, substantially contributed to the halocline collapse and onset of interstadial conditions throughout complex ocean-sea ice

    Several dwarf tomato and pepper varieties were evaluated under International Space Station (ISS)-simulated growth conditions (22 degrees Centigrade, 50 percent relative humidity, 1500 parts per million CO2, and 300 micromoles per square meter per second of light for 16 hours per day) with the goal of selecting those with the best growth, nutrition, and organoleptic potential for use in a pick and eat salad crop system on ISS and future exploration flights. Testing included six cultivars of tomato (Red Robin, Scarlet Sweet 'N' Neat, Tiny Tim, Mohamed, Patio Princess, and Tumbler) and six cultivars of pepper (Red Skin, Fruit Basket, Cajun Belle, Chablis, Sweet Pickle, and Pompeii). Plants were grown to an age sufficient to produce fruit (up to 106 days for tomato and 109 days for pepper) using Turface (arcillite) potting media with 18-6-8 control-release fertilizer and supplemental nutrient solution beginning around 60-days-age. Tomato fruits were harvested when they showed full red color, beginning around 70-days age and then at weekly intervals thereafter, while peppers were grown until fruits showed color and were harvested twice (first test) and just once at the end of the second test, with the final harvests including colored and green fruit. Plant sizes, yields, and nutritional attributes were measured and used to down-select to three cultivars for each species. In particular, we were interested in cultivars that were short (dwarf) but still produced high yields. Nutritional data included elemental (Ca, Mg, Fe, and K) content, vitamin K, phenolics, lycopene (for tomato), anthocyanin, lutein, and zeaxanthin. The three down-selected cultivars for each species were grown again and the harvested fruit sent to NASA's Johnson Space Center for sensory evaluation, which included overall acceptability, appearance, color intensity, aroma, flavor and texture. The combined data were compared and given weighting factors to rank the cultivars as candidates for testing in

    Simple Summary Cruelty to animals occurs during production, handling, transport, and slaughter in most countries where Islam is a major religion. Most of the people involved in this, such as those involved in the transport of animals, animal handlers, and butchers, are Muslims. However, many Muslims and Islamic religious leaders are not aware of this cruelty. Islam is a religion that shows compassion to animals as mentioned in the holy book Qur’an and sayings of the Prophet Mohammed (pbuh). This paper highlights what Islam says of the welfare of animals and how animal welfare can be improved by sensitizing all Muslims and religious leaders to the teachings on animal welfare in the Qur’an and the Hadiths so that they can influence their followers. Abstract Islam is a comprehensive religion guiding the lives of its followers through sets of rules governing the personal, social, and public aspects through the verses of the Holy Qur’an and Hadiths, the compilation of the traditions of Prophet Mohammed (pbuh), the two main documents that serve as guidelines. Islam is explicit with regard to using animals for human purposes and there is a rich tradition of the Prophet Mohammad’s (pbuh) concern for animals to be found in the Hadith and Sunna. Islam has also laid down rules for humane slaughter. In many countries animals are killed without pre-stunning. Regardless of pre-stunning, such meat should not be treated as halāl or at least be considered as Makrooh (detestable or abominable), because the animals have been beaten or treated without compassion during production, handling, transport, and slaughter. Many Muslims and Islamic religious leaders are not aware of the cruelty that is routinely inflicted on animals during transport, pre-slaughter, and slaughter in many Islamic countries. There is an urgent need to sensitize all Muslims to the teachings of animal welfare in the Qur’an and the Hadiths. A campaign is needed to apprise religious leaders of the current

    The equation of state (EOS) and pressure dependence of the transverse optical (TO) Raman-active mode of cubic boron nitride (cBN) are proposed for pressure calibration in the diamond anvil cell (DAC) at high temperatures. We determined the EOS and the pressure dependence of the TO mode of cBN in the laser heated DAC up to 70 GPa and 3300 K, and cross-checked the results with ambient pressure data, theoretical density functional calculations, and empirical relations. Moreover, the thermal EOS of Ir determined in the course of the same experiment was found to be similarly consistent. The proposed high temperature pressure scale may be further improved on the basis of simultaneous measurements of density and sound velocities at high P-T conditions, which would provide an independent pressure determination. This study is in progress and will be reported at the Meeting. We thank John K. Dewhurst, Sangeeta Sharma, Chrystele Sanloup, Eugene Gregoryanz for their contribution to this study. We acknowledge the European Synchrotron Radiation Facility for provision of synchrotron radiation facilities and we would like to thank Nicola Guignot and Mohamed Mezour for assistance with the XRD measurements.

    Solvation and ionization of strong acids such as HX (X=Cl, Br), HNO3 etc. have been subjected to many researchers (see for example refs. 1, 2, and references therein). In this study, the competitive adsorption of two strong acids, namely, HCl and HNO3 on/in the water clusters and the surface of crystalline ice slab containing 72 water molecules were investigated at the average temperatures below 140 K. The main tool of this study is on-the-fly molecular dynamics as implemented in the density functional code QUICKSTEP (3) which is part of CP2K package (4). The small water clusters containing both HNO3 and HCl with up to five water molecules were further checked with MP2 level ab initio calculations. The results will be discussed in terms of dynamics, structures, energetics and spectroscopic perspectives. 1. Buch, V.; Sadlej, J.; Aytemiz-Uras, N.; Devlin, J.

    We are using the technique [1] of positronium annihilation ratio spectroscopy (PsARS) to study the annihilation of 6 - 13 eV positrons colliding with CO. In this method we detect in coincidence (a) two 511 keV annihilation gamma rays, and simultaneously (b) two 300 - 460 keV gamma rays from the three gamma decay of ortho-Ps. The ratio of these signals R3γ/2γ versus positron impact energy reveals anomalous behavior for CO when compared with other gases [1] suggesting that some other mechanism than Ps formation is contributing to positron annihilation at an energy about 1 eV above the Ps formation threshold of 7.2 eV. Recognizing that the threshold for electronic excitation by positron impact is located where the anomalous R3γ/2γ behavior occurs suggests that we may be observing an effect where the positron is electronically exciting CO and temporarily binding to the molecule in a resonance-like state from which the positron can annihilate with an electron producing an enhanced 511 keV coincidence signal consistent with our measurements.

    Zheng, Xiaoming; Lowengrub, John; Cristini, Vittorio

    2005-11-01

    The impact of a drop upon an interface is studied using an axisymmetric adaptive level-set/finite element method. Under certain conditions, the drop will rebound off the interface before breaking through. The drop fluid and the fluid below the interface are identical. We characterize the behavior in terms of the relevant nondimensional parameters: the Reynolds number, the Weber number, and the viscosity and density ratios of the fluid components. One of the primary difficulties in performing numerical simulations of such flows is the accurate resolution of the lubrication forces that arise in the near contact region between the drop and interface. To overcome this difficulty, we use a spatially and temporally adaptive mesh together with a new, stable and accurate projection method for the Navier-Stokes equations and a mass-conserving level-set algorithm for capturing the motion of the drop and interface (J. Comp. Phys., v. 208, 2005). We validate our algorithm by successfully matching the recent experimental results on drop/interface impact by Mohamed-Kassim and Longmire (Phys. Fluids, v. 15, 2003).

    Bai, Jingsong

    A program MVFT3D of large-eddy simulation is developed and performed to solve the multi compressible Navier- Stokes equations. The SGS dissipation and molecular viscosity dissipation have been analyzed, and the former is much larger than the later. Our test shows that the SGS dissipation of Vreman model is smaller than the Smagorinsky model. We mainly simulate the experiment of fluid instability of shock-accelerated interface by Poggi in this paper. The decay of the turbulent kinetic energy before the first reflected shock wave-mixing zone interaction and its strong enhancement by re-shocks are presented in our numerical simulations. The computational mixing zone width under double re-shock agreement well with the experiment, and the decaying law of the turbulent kinetic energy is consistent with Mohamed and Larue's investigation. Also, by using MVFT3D we give some simulation results of the inverse Chevron model from AWE. The numerical simulations presented in this paper allow us to characterize and better understand the Richtmyer-Meshkov instability induced turbulence, and the code MVFT3D is validated.

  1. Off-Axis Cavity Ring Down Spectroscopy Based on a Continuous-Wave Optical Parametric Oscillator

    2011-06-01

    Continuous-wave cavity ring down spectroscopy (cw-CRDS) is a sensitive absorption technique for trace gas analysis. Although it is highly sensitivity and relatively fast, ring down repetition rate and spectral resolution are limited by the cavity free spectral range (FSR). Normally, the injected beam is mode matched to the lowest transverse electro-magnetic mode (TEM00) of the cavity. Light is coupled into the cavity only when standing wave condition is fulfilled. Scanning of the laser without variation of the cavity length leads to transmission comb where recorded ring down times are separated in frequency by the FSR. Recently Romanini et. al. reported an off-axis (OA) CRDS spectrometer operating in the 766 nm region where the FSR of the cavity was reduced by N = 4 times from the original. In this re-entrant condition the cavity length is chosen to provide degeneracy of transverse modes. If the injection is adequately off-axis the beam returns to the starting point after N round trips. This divides the FSR to N group of degenerated modes which are equally frequency-spaced. We present an OA-CRDS spectrometer (N = 4) based on a continuous-wave optical parametric oscillator (cw-OPO) operating in the mid-infrared region (2.75 - 3.45 μm). The measurement of formaldehyde (H_2CO) using an OA-CRDS spectrometer will be presented. J. Courtois, A. K. Mohamed and D. Romanini Opt. Express 18, (5), 1 March 2010.

    The gravity-driven motion of a droplet impacting on a liquid-liquid interface is studied. The full Navier-Stokes equations are solved on a fixed, uniform grid using a finite difference/front-capturing method. For the representation of fluid-fluid interfaces, a coupled Level-Set/Volume-Of-Fluid method [M. Sussman, E.G. Puckett, A coupled Level-Set and Volume-of-Fluid method for computing 3D and axisymmetric incompressible two-phase flows, J. Comp. Phys. 162 (2000) 301-337] is used, in which we introduce the novel approach of describing separate interfaces with different marker functions. As a consequence, we prevent numerical coalescence of the droplet and the liquid-liquid interface without excessive (local) grid refinement. To validate our method, numerical simulations of the drop impact event are compared with experiments [Z. Mohamed-Kassim, E.K. Longmire, Drop impact on a liquid-liquid interface, Phys. Fluids 15 (2003) 3263-3273]. Furthermore, a comparison is made with the numerical results of [A. Esmaeeli, G. Tryggvason, Direct numerical simulations of bubbly flows. Part 2. Moderate Reynolds number arrays, J. Fluid Mech. 385 (1999) 325-358] for an array of rising bubbles. The investigation shows that the multiple marker approach successfully prevents numerical coalescence of interfaces and adequately captures the effect of surface tension.

In this study, energy of formation and dynamics of the Bjerrum defects were investigated in the presence of small adsorbates, such as dimethyl ether, CO2 etc.. The main tool of this investigation is ab initio molecular dynamics as implemented in the density functional code QUICKSTEP [2] which is part of CP2K package [3]. A crystal slab of three bilayers of hexagonal ice containing 72 water molecules were used as a model. The energy cost for the formation of orientation defects that are solvated by adsorbates as well as trajectories calculated on DFT level will be presented. 1. Petrenko V. F. and Whitworth R.

    We are investigating ortho- and para-positronium (Ps) formation for positrons interacting with simple gas molecules in a gas scattering cell using Ps annihilation ratio spectroscopy (PsARS)[1]. These measurements involve the detection of two gamma rays in coincidence for energy windows (a) centered at 511 keV resulting from the decay of short-lived (0.1 ns) para-Ps and the destruction of longer-lived (0.1 μs) ortho-Ps at the scattering cell walls, and (b) from 300 to 460 keV resulting from the three gamma decay of ortho-Ps. By taking the ratios of these signals versus positron impact energy we find we are able to compare the resulting curves with that obtained for argon as a reference. These comparisons reveal departures from the argon curve at well defined energies and are interpreted as Ps formation with inner orbital electrons. The fractions of the overall Ps formation cross-section due to inner orbital electrons are estimated to be as high as 30% for O2, 25% for CO2, 15% for N2O and 5% for C2H2 near their respective threshold energies.

    Positrons, being the antiparticles of electrons, ultimately annihilate either directly with electrons (that are free or attached to atoms or molecules), or via the formation of positronium (Ps, a short-lived atom composed of a positron and an electron) with subsequent annihilation. In this work we have developed positronium annihilation ratio spectroscopy (PsARS), and are using PsARS to investigate the formation and destruction of Ps [1], as well as positron attachment to molecules. For this experiment a 3 to 100 eV positron beam obtained from a sodium-22 radioactive source is passed through a gas scattering cell and resulting annihilation gamma rays of different energies are detected in coincidence. Annihilation measurements, such as these, have astrophysical relevance since characteristic positron annihilation gamma rays have been observed from various extraterrestrial sources (e.g., solar flares and the direction towards the center of our galaxy).

    Bacteria play an important role in destructive periodontitis. The aim of this study was to screen for five highly pathogenic bacteria: Aggregatibacter actinomycetemcomitans, Porphyromonas gingivalis, Prevotella intermedia, Tannerella forsythia, and Treponema denticola, in Moroccan patients presenting with severe chronic periodontitis and to compare results with those of patients presenting with severe aggressive periodontitis. Twenty-three patients were included at the periodontology unit (School of dental medicine, University Mohammed 5 Souissi, Rabat, Morocco). The study was made on two groups: a test group of patients presenting with severe chronic periodontitis, and a control group of patients presenting with severe aggressive periodontitis. Plaque sampling was performed at the four deepest sites in each patient. The five studied bacteria were detected by PCR. The prevalence of A. actinomycetemcomitans and T. denticola was relatively low in the test group (13.3% and 20% respectively) compared with controls (37.5% and 37.5% respectively), without any statistical difference between the two groups. Furthermore, P. gingivalis and T. forsythia were frequently detected in both groups, without any statistical difference. The results of this preliminary study proved the presence of the studied periodontopathogenic bacteria both in severe chronic periodontitis and severe aggressive periodontitis.

    Terrestrial actinomycetes are noteworthy producers of a multitude of antibiotics, however the marine representatives are much less studied in this regard. In this study, 90 actinomycetes were isolated from 11 different species of marine sponges that had been collected from offshore Ras Mohamed (Egypt) and from Rovinj (Croatia). Phylogenetic characterization of the isolates based on 16S rRNA gene sequencing supported their assignment to 18 different actinomycete genera representing seven different suborders. Fourteen putatively novel species were identified based on sequence similarity values below 98.2% to other strains in the NCBI database. A putative new genus related to Rubrobacter was isolated on M1 agar that had been amended with sponge extract, thus highlighting the need for innovative cultivation protocols. Testing for anti-infective activities was performed against clinically relevant, Gram-positive (Enterococcus faecalis, Staphylococcus aureus) and Gram-negative (Escherichia coli, Pseudomonas aeruginosa) bacteria, fungi (Candida albicans) and human parasites (Leishmania major, Trypanosoma brucei). Bioactivities against these pathogens were documented for 10 actinomycete isolates. These results show a high diversity of actinomycetes associated with marine sponges as well as highlight their potential to produce anti-infective agents.

    Objectives. We conducted a one-year observational study from December 2012 to November 2013 to describe the epidemiology of bacteraemia in intensive care units (ICU) of Mohammed V Military Teaching Hospital of Rabat (Morocco). Methods. The study consisted of monitoring all blood cultures coming from intensive care units and studying the bacteriological profile of positive blood cultures as well as their clinical significance. Results. During this period, a total of 46 episodes of bacteraemia occurred, which corresponds to a rate of 15,4/1000 patients. The rate of nosocomial infections was 97% versus 3% for community infections. The most common source of bacteraemia was the lungs in 33%, but no source was identified in 52% of the episodes. Gram negative organisms were isolated in 83,6% of the cases with Acinetobacter baumannii being the most frequent. Antibiotic resistance was very high with 42,5% of extended-spectrum beta-lactamases (ESBLs) in Enterobacteriaceae and 100% of carbapenemase in Acinetobacter baumannii. The antibiotherapy introduced in the first 24 hours was adequate in 72% of the cases. Conclusions. Bloodstream infections in ICU occur most often in patients over 55 years, with hypertension and diabetes. The bacteria involved are mainly Gram negative bacteria multiresistant to antibiotics. Early administration of antibiotics significantly reduces patients mortality. PMID:28408938

  10. Religion and Animal Welfare-An Islamic Perspective.

    Islam is a comprehensive religion guiding the lives of its followers through sets of rules governing the personal, social, and public aspects through the verses of the Holy Qur'an and Hadiths, the compilation of the traditions of Prophet Mohammed (pbuh), the two main documents that serve as guidelines. Islam is explicit with regard to using animals for human purposes and there is a rich tradition of the Prophet Mohammad's (pbuh) concern for animals to be found in the Hadith and Sunna. Islam has also laid down rules for humane slaughter. In many countries animals are killed without pre-stunning. Regardless of pre-stunning, such meat should not be treated as halāl or at least be considered as Makrooh (detestable or abominable), because the animals have been beaten or treated without compassion during production, handling, transport, and slaughter. Many Muslims and Islamic religious leaders are not aware of the cruelty that is routinely inflicted on animals during transport, pre-slaughter, and slaughter in many Islamic countries. There is an urgent need to sensitize all Muslims to the teachings of animal welfare in the Qur'an and the Hadiths. A campaign is needed to apprise religious leaders of the current cruelty that occurs during transport and slaughter.

    To replace and avoid synthetic chemicals toxicity, there is a growing interest in the investigation of natural products from plant origin for the discovery of active compounds with antimicrobial properties. This work was devoted to determine chemical composition and antimicrobial properties of the EO of M. piperita harvested in the garden of the National Institute of Medicinal and Aromatic Plants of Morocco. Experiments have been conducted at the Microbial Biotechnology Laboratory at the Sciences and Technology Faculty, Sidi Mohamed Ben Abdellah University, Fez, Morocco. M. piperita oil was screened for its antimicrobial activity against seven bacteria and two fungi using broth microdilution method. Chemical EO analysis was performed using CPG/MS. The EO revealed menthol (46.32%), menthofuran (13.18%), menthyl acetate (12.10%), menthone (7.42%), and 1,8-cineole (6.06%) as the main constituents. The tested EO exhibited strong inhibitory effect against all tested microorganisms with minimum inhibitory concentrations ranging from 0.062% to 0.5% (v/v), except for Pseudomonas aeruginosa that was the least sensitive and was only inhibited by concentrations as high as 0.5% (v/v). The studied EO showed an antimicrobial potential. This reinforces its use as an alternative to chemical additives that can be applied to the food and drug industry.

    Cold spraying technique is a promising process fabricating high quality metallic coatings. This work concerns both numerical and experimental investigations of cold sprayed copper coating taking into account impact conditions including, particle velocities and temperature, gas pressure and material nature. The conducted numerical study is an examination of the deformation behavior of Cu particles sprayed onto steel substrate using Abaqus/explicit software, allowing a good understanding of the deposition characteristics of copper particles and the effect of particle velocity on the coating microstructure. The numerical results show that particle impact velocity has a significant effect on its morphology; Lagrangian method exhibits an excessive distortion of the elements in the case of high impact velocity and fine meshing size, whereas simulation of particle impact using arbitrary Lagrangian-Eulerian (ALE) method is close to the experimental observations.

    Thirty new species of benthic leptothecate hydroids were described and named from Patagonia in a 1991 PhD dissertation by Mohamed El Beshbeeshy. Although constituting nomina nuda under provisions of the International Code of Zoological Nomenclature (ICZN), the names of some species were used in several scientific publications between 1991 and 2011. In 2011, the dissertation of El Beshbeeshy was published in accordance with Article 8 of the ICZN. Several species-group names appearing in that work nevertheless fail to fully comply with certain articles of the code. The goal of this contribution is to review the nomenclatural availability of the names of those 30 new taxa, and to clearly establish the current status of El Beshbeeshy's material. Two of them were made available in 1999 as part of studies other than those of El Beshbeeshy, and correct authorship and date is here noted. Twenty-one of the nomina nuda were made available in a work published by El Beshbeeshy in 2011, although some constitute junior synonyms. Six of the new species-group names appearing in both the 1991 and 2011 works, established following a literature review of Patagonian species, were proposed without re-description, or designation of name-bearing types, or locations of such types. Most of them do not meet criteria of availability and remain nomina nuda. The status of each is discussed to avoid additional nomenclatural errors and continued taxonomic confusion.

    This paper presents an end-to-end framework for automatically detecting and segmenting blood cells including normal red blood cells (RBCs), connected RBCs, abnormal RBCs (i.e. tear drop, burr cell, helmet, etc.) and white blood cells (WBCs). Our proposed system contains several components to solve different problems regarding RBCs and WBCs. We first design a novel blood cell color representation which is able to emphasize the RBCs and WBCs in separate channels. Template matching technique is then employed to individually detect RBCs and WBCs in our proposed representation. In order to automatically segment the RBCs and nuclei from WBCs, we develop an adaptive level set-based segmentation method which makes use of both local and global information. The detected and segmented RBCs, however, can be a single RBC, a connected RBC or an abnormal RBC. Therefore, we first separate and reconstruct RBCs from the connected RBCs by our suggested modified template matching. Shape matching by inner distance is later used to classify the abnormal RBCs from the normal RBCs. Our proposed method has been tested and evaluated on different images from ALL-IDB,10 WebPath,24 UPMC,23 Flicker datasets, and the one used by Mohamed et al.14 The precision and recall of RBCs detection are 98.43% and 94.99% respectively, whereas those of WBCs detection are 99.12% and 99.12%. The F-measure of our proposed WBCs segmentation gets up to 95.8%.

    2017-05-01

    In this paper we study the existence of vortex-type solutions for a system of self-dual equations deduced from the mass-deformed Aharony-Bergman-Jafferis-Maldacena (ABJM) model. The governing equations, derived by Mohammed, Murugan, and Nastse under suitable ansatz involving fuzzy sphere matrices, have the new feature that they can support only non-topological vortex solutions. After transforming the self-dual equations into a nonlinear elliptic {2× 2} system we prove first an existence result by means of a perturbation argument based on a new and appropriate scaling for the solutions. Subsequently, we prove a more complete existence result by using a dynamical analysis together with a blow-up argument. In this way we establish that any positive energy level is attained by a 1-parameter family of vortex solutions, which also correspond to (constraint) energy minimizers. In other words, we register the exceptional fact in a BPS-setting that, neither a "quantization" effect nor an energy gap is induced upon the system by the rigid "critical" coupling of the self-dual regime.

    In this work we present the effect of HiPCO single walled carbon nanotubes (SWCNT) introduction into the conjugated polymer matrix poly(3-hexyl thiophene) (P3HT) on the structural and thermal stability of these nanocomposites. The P3HT/SWCNT nanocomposite films were prepared using chloroform and chlorobenzene as solvents and optimised ultrasonication duration. The prepared samples were analyzed by thermogravimetric analysis (TGA), X-ray diffraction and transmission electron microscopy (TEM) to study the effect of carbon nanotubes on the thermal stability and structure of the polymer matrix. The measurements carried out for different SWCNT loadings show that the thermal stability was enhanced for a 0.5 wt.%, but exhibits a decrease with increasing the SWCNT content. Our results prove the structural enhancement which is in favor of a better organisation for both P3HT chains and carbon nanotubes due to their interaction.

    North Algeria is one of the most seismically active regions on the western Mediterranean basin and it is related with the boundaries of the Eurasian and Nubian plates. We compiled an earthquake catalogue for the north western of Algeria, within the area -2°W-1°E and 34°N-37°N for the time span 1790 - 2016. To compile the earthquake catalogue we merge all available catalogues either national and international. Then we remove all duplicates and fake earthquakes. The lower level of the catalogue entries is set at M = 2.5. Nevertheless, the magnitudes reported on the catalogue are ML, Ms, Mb, Mw and macroseismic intensity. Thus, we develop new empirical relations to calculate the Mw from the different magnitudes and intensity suitable to the seismic hazard and geodynamic context of North Algeria.

    Multiple myeloma is a malignant proliferation of plasma cells, mainly affecting the bone marrow. It rarely occurs in young patients. The medical observation study reveals multiple myeloma discovered through a purulent pleurisy in a 28-year-old subject. This patient was admitted to the pneumology service of the Mohamed V military hospital in Rabat for a fever and dyspnea evolving into a context of poor general condition. Clinical examination found a right pleural fluid effusion syndrome. The pleural puncture reveals a germ-free exudative purulent fluid without plasma cells. The myeloma diagnosis was suspected due to the combination of an aplastic normochromic normocytic anemia at 4.5g/dL of hemoglobin, an accelerated erythrocyte sedimentation rate, hypercalcemia, renal failure and osteolytic lesions located mainly in the skull and pelvis area, oriented by electrophoresis and serum protein immunosubstraction revealing a narrow peak in monoclonal beta-2 globulin at 70.56g/L with a lambda monoclonal gammopathy with immunoglobulin G, and confirmed by the myelogram showing a 74% rate of bone marrow plasma cells. The occurrence of myeloma at a young age is rare and the purulent pleurisy without plasma cells is a rare form of presentation and represents a poor prognosis.

    Ischemic stroke is rare in young adults, but it is genuinely a serious situation giving the fact that it touch a very active part of our society. We report a series of 128 cases. The purpose is to analyze the risk factors, etiologies and outcomes of ischemic stroke in young adults in Marrakesh. Retrospective study performed at the Neurology department Mohammed VI universitary hospital in Marrakesh interesting 128 patients. The diagnosis of ischemic stroke was assessed through clinical and radiological confrontation. The age of our patients varied from 18 to 45 years old, 76 males and 52 females giving a male: female ratio of 1:46. Hypertension was the first risk factor involved with 63 (49.2%) cases, followed by smoking with 52 (40.6%) patients. The causes of ischemic stroke were characterized by the predominance of the cardio embolic origin with 43 (33.5%) cases, the existence of 14 (11%) cases of syphilitic arthritis, and the 52 (40.6%) cases of unknown etiologies. The authors stress the difficulties faced on supporting ischemic stroke in southern Morocco in particular when concerned by the etiological finding and the rehabilitation after the acute phase of the stroke. Our study points out the high incidence of embolic heart disease in our context. The lack of neurologists, low coverage of the population and the underestimation by physicians are factors that can explain why ischemic stroke remain undiagnosed.

    Organic photovoltaic cells (OPVCs) are based on a heterojunction electron donor (ED)/electron acceptor (EA). In the present work, the electron donor which is also the absorber of light is pentathiophene. The typical cells were ITO/HTL/pentathiophene/fullerene/Alq3/Al with HTL (hole transport layer) = MoO3, CuI, MoO3/CuI. After optimisation of the pentathiophene thickness, 70 nm, the highest efficiency, 0.81%, is obtained with the bilayer MoO3/CuI as HTL. In order to understand these results the pentathiophene films deposited onto the different HTLs were characterized by scanning electron microscopy, atomic force microscopy, X-rays diffraction, optical absorption and electrical characterization. It is shown that CuI improves the conductivity of the pentathiophene layer through the modification of the film structure, while MoO3 decreases the leakage current. Using the bilayer MoO3/CuI allows cumulating the advantages of each layer.

    ABSTRACT Ergonomics is much broader than preventing work‑related musculoskeletal disorders. The successful application of ergo‑ nomics assures high productivity, avoidance of illnesses and injuries, and increased satisfaction among workers. Unsuc‑ cessful application, on the other hand, can lead to work‑related musculoskeletal disorders (MSDs). This article sets forth broad important background information on ergonomics so that the dental practitioner can have a general awareness of ergonomic risk factors as well as some basis for understanding the ongo‑ ing dialogue about ergonomics, its diagnosis, treatment, and regulation. This article provides alternatives to be considered by the practitioner in light of the practitioner's own circumstances, experiences and goals. A practitioner wishing to improve his or her work environment, for whatever reason, may wish to follow an incremental approach to such efforts, as is briefy discussed here.

    The major challenge in wireless sensor networks is the reduction of energy consumption. Passive wireless sensor network is an attractive solution for measuring physical parameters in harsh environment for large range of applications requiring sensing devices with low cost of fabrication, small size and long term measurement stability. Batteryless temperature sensing techniques are an active research field. The approach developed in our work holds a promising future for temperature sensor applications in order to successfully reduce the energy consumption. The temperature sensor presented in this paper is based on the electromagnetic transduction principle using the integration of the high temperature sensitive material into a passive structure. Variation in temperature makes the dielectric constant of this material changing, and such modification induces variation in the resonant frequencies of high-Q whispering-gallery modes (WGM) in the millimeter-wave frequency range. Following the results achieved, the proposed device shows a linear response to the increasing temperature and these variations can be remotely detected from a radar interrogation.

    Numerical analysis has been performed on the motion of a spherical particle injected into high temperature thermal plasma flows in order to disclose the mechanisms of heat transfer enhancement and to establish reliable correlations for heat transfer between the plasma gas and the particle. In terms of fluid dynamics occurring, the Navier-Stokes equations were solved for Ar-H2 mixture plasma gas in a two-dimensional system by finite element method (FEM). Computational simulation was undertaken to model the correlations for fine spherical particles in Ar 25%-H2 75% as plasma gas from 1100 to 9100 K at atmospheric pressure. Our results reveal the general consensus of Nusselt number, followed by increasing deviations as the temperature increases. Additionally, a comparison between our data and the predictions of other published correlations are given.

    Multifunctional applications of textiles have been limited by the inability to spin important materials into yarns. Generically applicable methods are demonstrated for producing weavable yarns comprising up to 95 wt % of otherwise unspinnable particulate or nanofiber powders that remain highly functional. Scrolled 50 nm thick carbon nanotube sheets confine these powders in the galleries of irregular scroll sacks, whose observed complex structures are related to twist-dependent extension of Archimedean spirals, Fermat spirals, or spiral pairs into scrolls. The strength and electronic connectivity of a small weight fraction of scrolled carbon nanotube sheet enables yarn weaving, sewing, knotting, braiding, and charge collection. This technology is used to make yarns of superconductors, Li-ion battery materials, graphene ribbons, catalytic nanofibers for fuel cells, and Ti O2 for photocatalysis.

    The purpose of the present work is to treat numerically the problem of the steady mixed convection that occurs in a vertical cylinder, opened at both ends and filled with a succession of three fluid saturated porous elements, namely a partially porous duct. The flow conditions fit with the classical Darcy-Brinkman model allowing analysing the flow structure on the overall domain. The induced heat transfer, in terms of local and average Nusselt numbers, is discussed for various controlling parameters as the porous medium permeability, Rayleigh and Reynolds numbers. The efficiency of the considered system is improved by the injection/suction on the porous matrices frontier. The undertaken numerical exploration particularly highlighted two possible types of flows, with and without fluid recirculation, which principally depend on the mixed convection regime. Thus, it is especially shown that recirculation zones appear in some domain areas under specific conditions, obvious by a negative central velocity and a prevalence of the natural convection effects, i.e., turnoff flow swirls. These latter are more accentuated in the areas close to the porous obstacles and for weak permeability. Furthermore, when fluid injection or suction is considered, the heat transfer increases under suction and reduces under injection.

Effect of penicillamine therapy on circulating immune complexes in rheumatoid arthritis. The sera of 40 patients with severe progressive rheumatoid arthritis were examined for the presence of soluble immune complexes before penicillamine therapy was started, and again after treatment for a mean period of 14·4 months. The methods used were radiobioassay (macrophage uptake), Clq-binding capacity, and precipitation by 4% polyethylene glycol. Before treatment the sera of 37 patients showed significantly enhanced uptake of 125I-labelled aggregated human IgG by guinea pig macrophages. Treatment produced significant falls in mean erythrocyte sedimentation rate, differential agglutination titre, and serum IgG and IgM levels, and enhancing complexes (EC) decreased or disappeared in 20 patients. In 9 patients EC changed to inhibiting complexes, and in 8 EC levels were unchanged. In 6 of 8 patients with cutaneous vasculitis initially, both lesions and EC disappeared. The total protein and the IgG and IgM precipitated from patients' sera by 4% polyethylene glycol fell significantly on treatment. Antinuclear antibody titres were unchanged by penicillamine, and 3 patients acquired these antibodies during treatment. These findings suggest that penicillamine treatment in rheumatoid arthritis reduces the level of circulating soluble immune complexes in which IgM rheumatoid factor is a component. PMID:1086655

    Neuromyelitis optica (NMO) is a disabling inflammatory condition that targets astrocytes in the optic nerves and spinal cord. Recent advances led to the individualization of a set of conditions now referred as NMO spectrum disorder (NMOSD). To describe the prevalence and characteristics of NMO SD in north Algeria. The present study is a retrospective and descriptive work which took place in Nedir Mohamed teaching hospital, Tizi-Ouzou, Algeria. 938 Medical files of patients with CNS inflammatory demyelinating diseases were reviewed then patients with optic neuritis and/or myelitis were preselected. Patients who met the 2015 neuromyelitis optica spectrum disorders criteria were selected and analyzed 08 Patients (3.4%) met the 2015 criteria for neuromyelitis optica spectrum disorders, 3/8 (37.5%) were positive to AQ4-IgG and 5/8 (62.5%) were negative. Mean age of onset was 29 years, female to male ratio was 3:1, cerebral MRI was normal in 75% of cases and longitudinally extensive transverse myelitis was present in 75% of cases. 37/232 Patients (15.9%) were considered at high risk of neuromyelitis optica spectrum disorders The present study suggests that the spectrum of NMO disorders is a rare entity among patients with optic nerve and spinal cord demyelinating lesions in north Algeria. However, the lack of accurate AQ4-IgG test certainly underestimates its real prevalence. Copyright © 2015 Elsevier B.V. All rights reserved.

  10. A background to the feminist movement in Egypt.

    The origins of the feminist movement in Egypt can be traced back to the social restructuring that occurred during the reign of Mohammed Ali (1805-48). At that time, a debate raged over whether female education was essential to national development. Reformers such as Kassim Amin argued in favor of education for all women and condemned polygamy, supporting their arguments with references to the Koran. Women from the upper classes used their wealth, over which Muslim law gives them full control, to found hospitals, schools, and training centers. By 1914, there were 14 magazines devoted to women's issues. Women participated in anticolonial movements and nationalist party activities while continuing to advocate improvements in women's status. In 1924, Egypt became the 1st Islamic country to deveil women without state intervention. The Egyptian Feminist Party was founded in 1923, and the Women's Political Party was established in 1942 to coordinate the fight for women's equality and the revision of family law. Women's full political rights gained recognition when Egypt won independence in 1956, and the 1st female Minister, Hekmat Abu-Zaid, was appointed in 1962. Ironically, the feminist movement stagnated in the 1st few decades after independence as women's organizations became coopted into the state. The movement has been revitalized, however, by Islamic attacks on women's rights.

    We report a case of dramatic outcome of severe hemolytic disease in a newborn due to RH1 incompatibility. A newborn with A RH1 blood group was admitted in the Mohammed V Military Teaching Hospital for the problem of hydrops fetalis associated with RH1 incompatibility. The blood group of his mother, aged 31, was AB RH1-negative and that of his 37 year old father was A RH1. The mother had a history of 4 term deliveries, 3 abortions, and 1 living child. There was no prevention by anti-D immunoglobulin postpartum. The mother’s irregular agglutinin test was positive and the pregnancy was poorly monitored. The laboratory tests of the newborn showed a high total serum bilirubin level (30 mg/L) and macrocytic regenerative anemia (Hemoglobin=4 g/dL, mean corpuscular volume = 183 fL, reticulocytes count =176600/m3). The blood smear showed 1256 erythroblasts per 100 leukocytes, Howell–Jolly bodies and many macrocytes. The direct antiglobulin test was positive. He was transfused with red blood cell concentrates and treated with conventional phototherapy. The evolution was unfavourable; he died three days after the death of his mother. The monitoring of these high-risk pregnancies requires specialized centers and a close collaboration between the gynaecologist and the blood transfusion specialist to strengthen the prevention, as well as clinico-biological monitoring in patients with a history of RH1 fetomaternal alloimunization.

    The proposed work presents a numerical investigation of the melting of a phase change material (PCM: Paraffin wax P116) dispersed with nanoparticles (Al2O3) in a latent heat storage unit (LHSU). The latter is composed of a number of vertical and identical slabs of nano-enhanced phase change material (NEPCM) separated by rectangular channels through which passes heat transfer fluid (HTF: water). A mathematical model based on the conservation equations of mass, momentum and energy has been developed. The resulting equations are discretized using the finite volume approach. The numerical model has been validated by experimental and numerical results published in literature. Numerical investigations have been conducted to evaluate the effects of the volumetric fraction of nanoparticles, HTF mass flow rate and inlet temperature on the latent heat storage unit's thermal behaviour and performance. Modelling results show that the volumetric fraction, HTF mass flow rate and inlet temperature need to be designed to achieve a significant improvement in thermal performance.

    Pancreatic encephalopathy (PE) is a rare complication of acute pancreatitis. Our study reports 2 cases of patients with pancreatic encephalopathy, hospitalized and treated in the Intensive Care Unit of the Military Hospital of Instruction Mohammed V, Rabat. Patient age ranged between 43 and 54 years, our 2 cases involved a woman and a man. The pathophysiologic process of EP is still not well understood, many assumptions have been described in the literature; some authors have suggested that lipase and phospholipase A2 are involved in the pathological process of PE. Other factors including infections, fluid and electrolyte disturbances, hypoxemia and perturbations in blood glucose can be triggers. The diagnosis of pancreatic encephalopathy is easy to establish, clinical symptoms usually include confusion, amazement and psychomotor agitation, sometimes associated with neurological damages such as convulsions, headache, transient hemiparesis, dysarthria, difficulties in verbal expression and amnesia. Paraclinical tests, including brain MRI and electroencephalogram allow a definitive diagnosis. Treatment is primarily symptomatic aiming to fight against factors favoring the onset of neurologic signs using resuscitative measures based on severity of the situation. The prognosis depends on the severity of acute pancreatitis and its complications. In our study data are broadly comparable to those currently published by the majority of authors.

    Nigella sativa (NS) seeds have been used for medicinal purposes for centuries both as herbs and its oil. In Islam it is regarded as one of the greatest forms of healing medicine included in the medicine of prophet Mohammed. Huge number of studies have been carried out in recent years on the pharmacological effects of these seeds and also the possible relationship with their constituents. A number of these investigations emphasized the antimicrobial effect of them by using different extracts. In our study we have tried to use the normal human mechanism in digestion by using the ground seeds. A modified paper disc diffusion method was used to test the antibacterial effect of NS seeds. Clear inhibition of the growth of Staphylococcus aureus was observed by concentration of 300 mg/ml with distilled water (D.W.) as control , this inhibition was confirmed by using the positive control Azithromycin. The inhibition obtained was higher with Nigella sativa ground seeds from Hadramout (HNSGS) than with Nigella sativa ground seeds from Ethiopia (ENSGS). No inhibition was found in the growth of E.coli and Enterobacter. This was emphasized by using the positive control Ciprofloxacin. The positive inhibition may be attributed to the two important active ingredients of NS, Thymoquinone and melanin.

    A numerical work is carried out to investigate the heat transfer and fluid flow behaviors in a fin-and-flat-tube heat exchanger provided with complex vortex generators (CVGs). A new design of CVGs is proposed in the present paper, it consists of CVGs formed by two portions: a flat portion with various attack angles (β = 0°, 20°, 40° and 60°) and a curved portion with various curvature angles (α = 30°, 45° and 60°). Changes in CVGs position ratio (R*) inside the tube are also investigated and three values of R* are considered, namely: R* = 1.375, 1.750 and 2.125. Computations based on the finite volume method with the SIMPLE algorithm are conducted for the air flow. The Reynolds number is ranging from 25 to 400. The obtained results show that the vortex formed near the tubes is intensified by the flat potion of CVGs, and the curved tube guide the fluid flow towards the region behind the tubes, resulting thus in improved heat transfer rates. In a comparison with tubes without CVG, the new design suggested and especially the case with β = 60°, α = 60° and R* = 2.125 improve significantly the heat transfer (an increase by about 76%) with a moderate pressure loss penalty.

    The aim of this work is to analyze the natural convection phenomena and entropy generation of water-based Al2O3 nanofluids in square enclosure. The simulated domain corresponds to a square cavity heated from below and cooled from the top. The left and right walls are heated up to a height H = (3/4 W) and are adiabatic in the remaining part (1-H). Numerical investigations have been carried out based on coupled partial differential equations of momentum and energy which are solved using finite volume method. The effective thermal conductivity of the nanofluid was expressed by the Maxwell-Garnetts model however the dynamic viscosity was calculated according to the Brinkman formula. The obtained results were presented by average Nusselt number, streamlines, isotherms and entropy generation with various pertinent parameters, namely, Rayleigh number (100 ≤ Ra ≤ 106), volumetric fraction of nanoparticles (1% ≤ ϕ ≤ 4% ). It was found that the heat transfer increases with the increase of Rayleigh number and volume fraction. The choice of these parameters is important to obtain maximum enhancement of heat transfer with minimum entropy generation.

    Professor Steven L. Wechsler, a world-renowned eye researcher and virologist, passed away unexpectedly on June 12, 2016 at the age of 68. Many scientists came to know Professor Wechsler as a gifted researcher in the field of ocular Herpes Simplex Virus (HSV-1) latency, reactivation, and pathogenesis. Professor Wechsler published over 150 peer-reviewed scientific papers during his career, pushing forward the frontiers of his field eye research. His colleagues would say, 'Steve literally wrote the book on herpes latency and reactivation.' He was the first to show that the HSV-1 latency-associated transcript (LAT) is essential for the HSV-1 high spontaneous reactivation phenotype and that LAT has anti-apoptosis activity. This discovery of LAT's anti-apoptosis activity, which is a key factor in how the LAT gene enhances reactivation, was published in Science in 2000 and created a new paradigm that greatly increased understanding of HSV-1 latency and reactivation. In collaboration with Professor Lbachir BenMohamed, an immunologist, they later demonstrated that LAT also acts as an immune evasion gene. He was a caring scientist who truly enjoyed working and sharing his experience and expertise with young researchers. He will be remembered as a significant pillar within scientific and ocular herpes research communities worldwide. Professor Wechsler's dedication to science, his compassionate character, and wonderful sense of humor were exemplary. We, who were his friends and colleagues, will mourn his passing deeply.

    The study has been designed as a case report. The objective of this study was to report a rare case of syringomyelia in a patient with syphilitic spinal meningitis. The Neurology Department, University Hospital Mohamed VI Marrakesh, Morocco. A 40-year-old Moroccan male presented with the complaints of weakness of the lower extremities. Neurological examinations confirmed the motor dysfunction of the lower extremities and revealed a sensory loss to the T2-T4 dermatome. The magnetic resonance imaging (MRI) scan detected a hypointense signals on the T1 sequences and hyperintense signals on T2 in the cord extending from C7 to T4. The condition was diagnosed as dorsal syringmyelia. Blood and cerebrospinal fluid were positive for Venereal Disease Research Laboratory and Treponema pallidum hemagglutination tests. The patient was treated with intravenous penicillin therapy with a significant improvement in motor deficit. After 2 years, his neurological deficit was limited to a mild weakness of the distal right leg. A case of syphilitic spinal meningitis presenting with syringomyelia, and effectively treated with penicillin has been described.

  19. Low Decision Space Means No Decentralization in Fiji Comment on "Decentralisation of Health Services in Fiji: A Decision Space Analysis".

    2016-06-22

    Mohammed, North, and Ashton find that decentralization in Fiji shifted health-sector workloads from tertiary hospitals to peripheral health centres, but with little transfer of administrative authority from the centre. Decision-making in five functional areas analysed remains highly centralized. They surmise that the benefits of decentralization in terms of services and outcomes will be limited. This paper invokes Faguet's (2012) model of local government responsiveness and accountability to explain why this is so - not only for Fiji, but in any country that decentralizes workloads but not the decision space of local governments. A competitive dynamic between economic and civic actors that interact to generate an open, competitive politics, which in turn produces accountable, responsive government can only occur where real power and resources have been devolved to local governments. Where local decision space is lacking, by contrast, decentralization is bound to fail because it has not really happened in the first place. © 2016 The Author(s); Published by Kerman University of Medical Sciences.

    The goals of this special section are to examine the state-of-the-science regarding race/ethnicity and racism as they contribute to health disparities and to articulate a research agenda to guide future research. In the first paper, Myers presents an integrative theoretical framework for understanding how racism, poverty, and other major stressors relate to health through inter-related psychosocial and bio-behavioral pathways. Williams and Mohammed review the evidence concerning associations between racism and health, addressing the multiple levels at which racism can operate and commenting on important methodological issues. Klonoff provides a review and update of the literature concerning ethnicity-related disparities in healthcare, and addresses factors that may contribute to these disparities. Brondolo and colleagues consider racism from a stress and coping perspective, and review the literature concerning racial identity, anger coping, and social support as potential moderators of the racism-health association. Finally, Castro and colleagues describe an ecodevelopmental model that can serve as an integrative framework to examine multi-level social-cultural influences on health and health behavior. In aggregate, the special section papers address theoretical and methodological issues central to understanding the determinants of health disparities, with the aim of providing direction for future research critical to developing effective interventions to reduce these disparities.

This symposium addressed factors linking stress plasticity and reactivity to stress pathology in animal models and in humans. Dr. Jason Radley discussed studies demonstrating prefrontal cortical neuroplasticity and prefrontal control of hypothalamo-pituitary-adrenocortical axis function in rat, highlighting emerging evidence for a critical role of this region in normal and pathological stress integration. Dr. Mohamed Kabbaj summarized his studies of possible epigenetic mechanisms underlying behavioral differences in rat populations bred for differential stress reactivity. Dr. Lauren Jacobson described studies using a mouse model to explore the diverse actions of antidepressant action in brain, suggesting mechanisms whereby antidepressants may be differentially effective in treating specific depression endophenotypes. Dr. Rachel Yehuda discussed the role of glucocorticoids in post-traumatic stress disorder (PTSD), indicating that low cortisol may be a trait that predisposes the individual to development of the disorder. Furthermore, she presented evidence indicating that traumatic events can have transgenerational impact on cortisol reactivity and development of PTSD symptoms. Together, the symposium highlighted emerging themes regarding the role of brain reorganization, individual differences and epigenetics in determining stress plasticity and pathology. PMID:21848436

    Burn injuries are most commonly encountered during natural disasters or disasters related to human activity (accidental fires in public places, in time of war, or in terrorist attacks). The care and triage of a large number of burn patients is a difficult problem, which requires adequate planning and emergency preparedness in anticipation of such crises. The training and readiness of doctors and paramedics is of utmost importance. The challenges are many: burn treatment requires a large and qualified staff; evacuations should be prioritized according to the severity of the burn and associated injuries; stocks (especially in topical anti-infective and crystalloid) should be sufficient and appropriate; and hospital services in a military training hospital Mohammed V such as there is in Rabat must be able to be quickly adapted to accommodate and isolate these particular patients. The hypothesis of a fire disaster with a mass influx of burn patients at this hospital should leave no room for improvisation, or else the prompt and accurate prognosis of the patients could be severely hindered.

    Different configurations of organic Rankine cycle (ORC) systems are potential thermodynamic concepts for power generation from low grade heat. The aim of this work is to investigate and optimize the performances of the three main ORC systems configurations: basic ORC, ORC with internal heat exchange (IHE) and regenerative ORC. The evaluation for those configurations was performed using seven working fluids with typical different thermodynamic behaviours (R245fa, R601a, R600a, R227ea, R134a, R1234ze and R1234yf). The optimization has been performed using a genetic algorithm under a comprehensive set of operative parameters such as the fluid evaporating temperature, the fraction of flow rate or the pressure at the steam extracting point in the turbine. Results show that there is no general best ORC configuration for all those fluids. However, there is a suitable configuration for each fluid.

    In this paper we study the existence of vortex-type solutions for a system of self-dual equations deduced from the mass-deformed Aharony-Bergman-Jafferis-Maldacena (ABJM) model. The governing equations, derived by Mohammed, Murugan, and Nastse under suitable ansatz involving fuzzy sphere matrices, have the new feature that they can support only non-topological vortex solutions. After transforming the self-dual equations into a nonlinear elliptic {2× 2} system we prove first an existence result by means of a perturbation argument based on a new and appropriate scaling for the solutions. Subsequently, we prove a more complete existence result by using a dynamical analysis together with a blow-up argument. In this way we establish that any positive energy level is attained by a 1-parameter family of vortex solutions, which also correspond to (constraint) energy minimizers. In other words, we register the exceptional fact in a BPS-setting that, neither a "quantization" effect nor an energy gap is induced upon the system by the rigid "critical" coupling of the self-dual regime.

Moving the top surface horizontally at a fixed speed, while two vertical walls are applied with constant different temperatures, assuming adiabatic case on both bottom and top walls. We consider a "non-cooperating" situation, where dynamics and buoyancy forces counterbalance. The cavity contains a circular cylinder placed at various positions. Boundary conditions for velocity and temperature have been applied to handle the non-Cartesian boundary of the cylinder. In lattice Boltzmann methods we adopt the double distribution model for calculating both the thermal and hydrodynamic fields. The D2Q5 and D2Q9 lattice are chosen to perform the simulations for a wide range of Reynolds and Rayleigh numbers. By calculating the average Nusselt number, we also investigated the influence of different obstacle positions on characteristics of flow and heat transfer. The results show the influence of the obstacle position on the dimensionless numbers, so as to effect the heat transfer behaviors inside the cavity. It is also indicates that the governing parameters are also related to driven power for the upper surface sliding.

    Hypokinesia (lack of exercise)--a disease caused by lack of physical activity leads among others to a predominance of the sympathetic nerve in the circulation. Its manifestations are briefly described according to Kraus-Raab's hypothesis of 1961. The opposite of a hypokinetic man are trained (hyperkinetic) sportsmen, in particular long-distance runners. Their neurovegetative balance is shifted to the side of the vagus (parasympathetic nerve). This is described as training vagotonia. On the example of ECG tracings of an Olympic 5 km runner, the Tunisian Mohamed Gammoudi, the author describes its manifestations at rest, during the orthostatic test and during work, i.e. the step test. These manifestations include in particular bradycardia of 32 beats per minute, prolonged atrioventricular conduction > 0.2 sec., a long period of the electric systole = 0.44 sec. and an enormously prolonged electric diastole T-P = 1.1 sec. This long diastolic filling stage makes it possible in particular during physical work to increase the systolic and diastolic output to double the values of a healthy non-trained heart. Training vagotonia is usually not the source for manifestation of dangerous arrhythmias, as it may be the case in constitutional vagotonia. So far expert comparison of these two types of change to parasympathic tonus is lacking, similarly as a comparative study with medicamentously influenced vagotonia by means of beta-blockers.

    Between 5 and 30% of patients with Behçet's disease will present neurological signs during the course of their illness. In order to evaluate the radiological signs on neuro-behçet disease, we studied consecutive patients in whom the diagnosis of this disease was retained, and who referred from January 2004 to December 2011 to the neurology and internal medicine departments in Mohammed VI universitary hospital in Marrakesh. Using 1.5T magnetic resonance imaging (MRI) with axial and coronal T2- weighted, axial Fluid Attenuated Inversion Recovery (FLAIR), pre- and post-contrast axial, coronal and sagittal T1-weighted sequences. The final number of patients in whom the diagnosis criteria of behçet disease were fulfilled and in whom an MRI was performed was 68 cases. Among these patients, 52 had parenchymal form of neuro-behçet with abnormalities in the MRI, 12 had vascular form and 4 patients had normal MRI. The brainstem, cerebral white matter, basal ganglia, internal capsule, thalamus and spinal cord were involved in forty four, thirty one, thirty, twenty nine, seventeen and four patients, respectively. The cerebral peduncle was the brainstem structure mainly involved with thirty cases followed by the pons with, twenty cases. Midbrain involvement interested forty patients. Brainstem atrophy was seen in eighteen cases. Finally, control MRI were obtained in four cases only, and showed changes in lesions size and shape.

    In the framework of several projects sustained by the Regional Sardinian Government Laws no. 43 (28/09/1990) and no. 19 (11/04/1996), research groups of the University of Cagliari (Sardinia, Italy) and of the University Mohamed V-Agdal of Rabat (Morocco) have started a series of preliminary geo-environmental studies in the basin of the Oued Sebou. An area of almost 1000 square km around the famous city of Fès has been studied, using satellite images and two ground surveying campaigns. These surveys aim to define the geological and structural settings, the vegetation and land use, in order to define the landscape units and to select the areas of major hydrogeological and geo-environmental risk. The satellite data used are the LANDSAT TM5 images taken on the 9th of October 1997. These images have been analysed to obtain the different bases for further thematic mapping, resulting in the geo-environmental map of the area around Fès that constitutes an up-to-date representation of the geological and environmental state of the territory and a useful instrument for further risk assessment and urban and territorial planning.

    The purpose of this paper is to numerically examine the conjugate surface radiation-natural convection heat transfer in a 2D differentially heated enclosure with an inner square body, which generates heat. The numerical model is based on the coupling of the MRT-lattice Boltzmann model with finite difference method (FDM). The first one is used to compute the velocity field, while the second is adopted to obtain the temperature field. Various key parameters are studied, such as Rayleigh number (103 ≤ Ra ≤ 106), temperature-difference ratio ΔT*(0 ≤ ΔT* ≤ 50), body's thermal conductivity (0 < Ks < ∞) and locations. In this study, the air is considered as perfectly transparent to radiation. Among the salient findings, we can state that (i) the inner body location has a meaningful effect on isotherms, streamlines and total heat transfer through the enclosure, (ii) the heat transfer is affected considerably by increasing the body size and radiation exchange, specially at high Ra.

    Breast cancer is most common in women and it is among the leading causes of cancer related deaths. The curability of this type of tumor is increasing thanks to screening programs and treatment advances which have certainly enhanced patient survival. But challenges remain, particularly in respect of phenotypic instability of cancer cells. The aim of this study was to analyse the phenotypic profile of breast cancer in patients treated at Mohammed VI Cancer Treatment Center over the years 2013-2014. We conducted a cross-sectional study over a two-year period, including the cases of breast cancer treated in our Center. Data were collected from patients medical records and analyzed using Epi Info software. 1277 patients were treated in our Center. 99.5% were females, mean age 50.20 ± 11.34 years. The most common histological type was invasive ductal carcinoma (80.7% of cases). It was diagnosed at an early stage (56,9%). The most common molecular phenotype was luminal A (41.4% of cases). Luminal B, HER2 and triple negatives occurred in 10.4%, 6.3%, 11.2% of cases respectively. The study of tumor phenotype in patients with breast cancer helps clinician make treatment choice and policy makers implement programs against this disease.

  14. U-Form vs. M-Form: How to Understand Decision Autonomy Under Healthcare Decentralization?

    For more than three decades healthcare decentralization has been promoted in developing countries as a way of improving the financing and delivery of public healthcare. Decision autonomy under healthcare decentralization would determine the role and scope of responsibility of local authorities. Jalal Mohammed, Nicola North, and Toni Ashton analyze decision autonomy within decentralized services in Fiji. They conclude that the narrow decision space allowed to local entities might have limited the benefits of decentralization on users and providers. To discuss the costs and benefits of healthcare decentralization this paper uses the U-form and M-form typology to further illustrate the role of decision autonomy under healthcare decentralization. This paper argues that when evaluating healthcare decentralization, it is important to determine whether the benefits from decentralization are greater than its costs. The U-form and M-form framework is proposed as a useful typology to evaluate different types of institutional arrangements under healthcare decentralization. Under this model, the more decentralized organizational form (M-form) is superior if the benefits from flexibility exceed the costs of duplication and the more centralized organizational form (U-form) is superior if the savings from economies of scale outweigh the costly decision-making process from the center to the regions. Budgetary and financial autonomy and effective mechanisms to maintain local governments accountable for their spending behavior are key decision autonomy variables that could sway the cost-benefit analysis of healthcare decentralization.

    To replace and avoid synthetic chemicals toxicity, there is a growing interest in the investigation of natural products from plant origin for the discovery of active compounds with antimicrobial properties. This work was devoted to determine chemical composition and antimicrobial properties of the EO of M. piperita harvested in the garden of the National Institute of Medicinal and Aromatic Plants of Morocco. Experiments have been conducted at the Microbial Biotechnology Laboratory at the Sciences and Technology Faculty, Sidi Mohamed Ben Abdellah University, Fez, Morocco. M. piperita oil was screened for its antimicrobial activity against seven bacteria and two fungi using broth microdilution method. Chemical EO analysis was performed using CPG/MS. The EO revealed menthol (46.32%), menthofuran (13.18%), menthyl acetate (12.10%), menthone (7.42%), and 1,8-cineole (6.06%) as the main constituents. The tested EO exhibited strong inhibitory effect against all tested microorganisms with minimum inhibitory concentrations ranging from 0.062% to 0.5% (v/v), except for Pseudomonas aeruginosa that was the least sensitive and was only inhibited by concentrations as high as 0.5% (v/v). The studied EO showed an antimicrobial potential. This reinforces its use as an alternative to chemical additives that can be applied to the food and drug industry. PMID:28795021

    The objective of this research was to develop ecological adhesives for bonding plywood panels using lignosulfonates, a common waste product of the wood pulp industry, and natural tannin extracted from Moroccan bark of Acacia mollissima using different process. Natural tannin and lignin were used in wood adhesives formulation to substitute resins based on phenol and formaldehyde. To achieve this, the lignosulfonates were glyoxalated to enhance their reactivity and the used tannins obtained by three different extraction methods were compared with commercial mimosa tannin. The proportion of Acacia mollissima tannins and lignosulfonates, the pressing time, the pressing temperature, and the pressure used were studied to improve mechanical properties, and bonding quality of plywood panel. The properties of plywood panels produced with these adhesives were tested in accordance with normative tests. Thus, the tensile strength, and the shear strength were measured. The results showed that the performance of the plywood panels made using biobased tannin adhesives was influenced by physical conditions such as pressure, press temperature as well as by chemical conditions, such as the tannin-lignin ratio. It exhibited excellent mechanical properties comparable to commercially available phenol-formaldehyde plywood adhesives. This study showed that biobased adhesives formulations presented good and higher mechanical performance and no formaldehyde emission.

    The durability of SiO2 compounds is closely related to its structural properties. In this work three natural siliceous aggregates (called G1, G2 and G3) are studied. Improvement of the durability of the starting material leads to a significant energy savings by extending the lifetime of structures. The chemical composition of the three natural aggregates shows that G1 and G2 have almost the same chemical composition (SiO2) and G3 is different and contains SiO2 quartz type and calcite as major components (SiO2, calcite and dolomite). X-ray diffraction (XRD) shows that natural aggregates G1 is more crystallized than G2 and G3. After alkali silica reaction (ASR) process, the reactivity of G3 aggregate seems to be higher than the G1 and G2 aggregates. The mechanical results show the slight difference between mortar containing G1 (M_G1) and that containing G2 (M_G2). Their compressive strength is 10% less than that of reference (M_SS). As it is more reactive, G3 seems improving the compressive strength of M_G3, compared to M_G1 and M_G2.

    Here we report first time the direct observation of the nucleation and growth process of cadmium sulfide (CdS) nanowires by stirring of CdS nanoparticles. The growth process of CdS nanowires consist of three steps, the growth of CdS particles, nucleation of CdS nanorods and finally the growth of CdS nanowires. This method brings forward a new idea to synthesize nanowires. The X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive X-ray (EDAX), ultraviolet-visible (UV-Vis) and photoluminescence (PL) spectra have been provided for the characterization of the as-obtained nanowires. Furthermore, carboxylic functionalize porphyrin was examined as sensitizer for CdS nanowires. The interaction of porphyrin with CdS nanowires was investigated by absorption, infrared, steady state fluorescence spectroscopy and SEM techniques. The hybrid devices were fabricated with organic polymer with different concentration of dyes and the device with optimum concentration 6 × 10-6 M shows the highest efficiency of 0.5% with short-circuit current density 3.10 mA cm-2, open-circuit voltage 0.44 V and fill factor 0.37.

    We perform a contribution with a simulation study of the mixed convection in horizontal channel heated from below. The lattice Boltzmann method (LBM) is used with the Boussinesq approximation to solve the coupled phenomenon that governs the systems thermo-hydrodynamics. The double populations thermal lattice Boltzmann model (TLBM) is used with the D2Q5 for the thermal field and D2Q9 model for the dynamic field. A comparison of the results of the averaged Nusselt number obtained by the TLBM with other references is presented for an area stretching. The streamlines, the vortices, the isotherms, the velocity profiles and other parameters of the study, are presented at a certain time tT which is chosen arbitrarily. The results presented here are in good agreement with those reported in the scientific literature which gives us high expectations about the reliability of the TLBM to simulate this kind of physical phenomena.

    Large disturbances can cause rapid degradation of coral reef communities, but what baseline changes in species assemblages occur on undisturbed reefs through time? We surveyed live coral cover, reef fish abundance and fish species richness in 1997 and again in 2007 on 47 fringing patch reefs of varying size and depth at Mersa Bareika, Ras Mohammed National Park, Egypt. No major human or natural disturbance event occurred between these two survey periods in this remote protected area. In the absence of large disturbances, we found that live coral cover, reef fish abundance and fish species richness did not differ in 1997 compared to 2007. Fish abundance and species richness on patches was largely related to the presence of shelters (caves and/or holes), live coral cover and patch size (volume). The presence of the ectoparasite-eating cleaner wrasse, Labroides dimidiatus, was also positively related to fish species richness. Our results underscore the importance of physical reef characteristics, such as patch size and shelter availability, in addition to biotic characteristics, such as live coral cover and cleaner wrasse abundance, in supporting reef fish species richness and abundance through time in a relatively undisturbed and understudied region.

  6. Calibrating and Measuring Bedload Transport Using a Magnetic Detection System

    2004-12-01

    One of the problems in bedload transport research is that no measurement technique has been commonly accepted as superior, and there are no standard protocols. There is a need for continuous bedload measurement to adequately resolve patterns in temporal and spatial variability, especially at high transport rates. Magnetic detection systems are a promising method as they can sense the movement of natural stones, and provide high frequency data in both time and space. A number of magnetic systems have been deployed in the field, but they have not been adequately calibrated. This has limited the analysis to counting the number of pulses, and not allowed confident estimations of the true amount of sediment transport, sediment texture or particle velocities. We developed a series of lab and flume experiments to calibrate the BMD system used by Tunnicliffe et al (2000). Experiments were run with both artificial and natural stones to isolate the effects of particle size, velocity and magnetic content (susceptibility and moment) on the shape of the recorded signal. A large number of experiments were conducted to cover wide range of flow conditions, particle sizes, and particle velocities. The results show that the system is sensitive enough to detect particles down to at least 8mm. Using artificial stones we were able to relate the signal amplitude, width and area to particle size, velocity and magnetic content. These results suggest that the magnetic system can be used to estimate transport rates in natural streams. Work is continuing with natural stones both in the laboratory and the field to further develop of the system. Tunnicliffe, J., Gottesfeld, A.S., and Mohamed, M. 2000.

    The Maghrebides, Betics and some parts of the Calabrian, NE Sicilian and Tuscan allochtons constitute dismembered fragments of the Alpine belt that resulted from the Cenozoic collision between Africa and Eurasia and the opening of the Western Mediterranean basin. Mineral and whole-rock geochemical analyses have been performed on three distinct outcrops of mantle material from the Edough Massif of NE Algeria, namely the Bou Maiza (BM) gabbros, the La Voile Noire (LVN) amphibolites and the Sidi Mohamed (SM) peridotites. In all samples, Sr isotopes are largely affected by seawater alteration (87Sr/86Sract. > 0.70384 and up to 0.70888) and cannot be used to evaluate the nature of the source reservoirs. SM peridotites display variable depleted mantle Nd isotopic signatures (εNdact. from + 7.0 to + 12.2) and geochemical features suggesting no significant chemical depletion as a result of partial melting and melt extraction (Mg# < 90; slightly LREE-depleted patterns with La/YbN = 0.33-0.39). These rocks are interpreted as parts of the subcontinental lithospheric mantle incorporated into the crustal units of the Edough Massif during the early stages of opening of the Algerian basin. BM gabbros and LVN amphibolites show geochemical signatures indicating derivation from a common depleted mantle reservoir (εNd > + 7.9) and are likely cogenetic, but without filiation with the SM peridotites. Pb isotopes indicate a contribution of sediments in the source reservoir, which is attributed to contamination solely by hydrous fluids released from a sedimentary component. This observation, together with a LILE-enrichment, suggests a back-arc basin environment. These results indicate that BM and LVN units were obducted onto the North African margin and subsequently fragmented, probably during doming and exhumation of the lower continental crust of the Edough massif. Doming resulted in opposite movements of the overlying oceanic units, southward for the BM units and northward for LVN

Limestone is one of the most frequent building stones in Egypt and is used since the time of ancient Egyptians and salt weathering is one of the main threats to its conservation. Most of the limestone used in historical monuments in Cairo is a biomicrite extracted from the Mid-Eocene Mokattam Group. During this work, cylindrical samples (2.4 cm diameter and approx. 4.8 cm length) were subjected, in a purpose-made simulation chamber, to simulated laboratory weathering tests with fixed salt concentration (10% weight NaCl solution), at different temperatures, which were kept constant throughout each test (10, 20, 30, 40 oC). During each test, salt solutions flowed continuously imbibing samples by capilarity. Humidity within the simulation chamber was reduced using silica gel to keep it low and constant to increase evaporation rate. Temperature, humidity inside the simulation chamber and samples weight were digitally monitored during each test. Results show the advantages of the proposed experimental methodology using a continuous flow of salt solutions and shed light on the effect of temperature on the dynamics of salt crystallization on and within samples.

    Precise and efficient numerical simulation of transport processes in subsurface systems is a prerequisite for many site investigation or remediation studies. Random walk particle tracking (RWPT) methods have been introduced in the past to overcome numerical difficulties when simulating propagation processes in porous media such as advection-dominated mass transport. Crucial for the precision of RWPT methods is the accuracy of the numerically calculated ground water velocity field. In this paper, a global node-based method for velocity calculation is used, which was originally proposed by Yeh (Water Resour Res 7:1216-1225, 1981). This method is improved in three ways: (1) extension to unstructured grids, (2) significant enhancement of computational efficiency, and (3) extension to saturated (groundwater) as well as unsaturated systems (soil water). The novel RWPT method is tested with numerical benchmark examples from the literature and used in two field scale applications of contaminant transport in saturated and unsaturated ground water. To evaluate advective transport of the model, the accuracy of the velocity field is demonstrated by comparing several published results of particle pathlines or streamlines. Given the chosen test problem, the global node-based velocity estimation is found to be as accurate as the CK method (Cordes and Kinzelbach in Water Resour Res 28(11):2903-2911, 1992) but less accurate than the mixed or mixed-hybrid finite element methods for flow in highly heterogeneous media. To evaluate advective-diffusive transport, a transport problem studied by Hassan and Mohamed (J Hydrol 275(3-4):242-260, 2003) is investigated here and evaluated using different numbers of particles. The results indicate that the number of particles required for the given problem is decreased using the proposed method by about two orders of magnitude without losing accuracy of the concentration contours as compared to the published numbers.

    We present the results of photo-polarimetric observations for asteroids 9 Metis (S-type, main belt asteroid (MBA)), 52 Europa (C-type, MBA), and 1036 Ganymed (S-type, near-Earth asteroid), obtained at six wavelength bands. It is found, combining our new data with previous observations, that (1) larger maximum value of negative polarization Pmin=-1.37% and higher polarization slope h=0.27% deg -1 occur in 52 Europa, while smaller Pmin and lower h appear, i.e., -0.84%, 0.11% deg -1 for 9 Metis and -0.57%, 0.095% deg -1 for 1036 Ganymed. These results confirm the general trend of polarization-phase angle curves found previously between C- and S-type asteroids (see B. Goidet-Devel et al. 1995, Planet Space Sci.43, 779-786). (2) An increase of polarization with wavelength from 0.42 to 0.76 μm is found from the data with their root-mean-square errors in 9 Metis and 1036 Ganymed, in contrast with vice versa dependence in 52 Europa. (3) A relation of Pmin and geometric albedo A, presented in D. F. Lupishko and R. A. Mohamed (1996, Planet Space Sci.46, 47-74), leads to the resulting values of A for 0.15, 0.082, and 0.24 for 9 Metis, 52 Europa, and 1036 Ganymed, respectively. (4) The polarization observed for 9 Metis shows a significant time variation modified with the rotation of asteroid, but no clear relation between lightcurve and polarization curve appears. For 52 Europa and 1036 Ganymed, the observed time variation of polarization is weak. (5) A comparison of model simulation to the observations of lightcurve and geometric albedo A variation for 9 Metis suggests the existence of inhomogeneous albedo features on its surface, where the albedo was derived from the relation of Pmin and A.

    High-speed tomographic PIV was used to obtain evolving volumetric velocity fields of the coalescence of single drops and two side-by-side drops through liquid/liquid interfaces. Reynolds numbers (Re=ρsUσD/μs) based on surface tension velocity (Uσ=D/tσ) and surrounding ambient fluid were 8-10, and the viscosity ratio between the fluid drop and surrounding fluid was 0.14. The coalescence process investigated is driven by gravity and thus the initial drops are non-spherical and the interface is deformed by the drops. Previously, Mohamed-Kassim & Longmire (2004) showed that under these conditions, the film rupture typically occurs off-axis, and therefore the flow is three-dimensional. For a single drop, volumetric velocity vector fields are used to characterize the asymmetric film rupture occurring for 0

    We are investigating Positronium (Ps) formation for < 20 eV positrons interacting with N2 in a gas scattering cell. The technique [1] of Ps annihilation ratio spectroscopy (PsARS) is used to obtain the ratios of coincidence signals for two of the three gamma rays (S3γ) in the photon energy window 300 to 460 keV resulting from ortho-Ps decay to that for two 511 keV gamma rays (S2γ) arising from para-Ps decay and other processes. By comparing these ratios of S3 γ/S2γ for N2 to those for Ar it is found that N2 exhibits strikingly anomalous behavior near and below the Ps formation threshold. Typically, this ratio remains constant within 2 eV above the Ps threshold. For N2, this ratio decreases to zero at the threshold and an S2 γ signal remains for an energy of ˜0.3 eV below. Since N2 has an electronic excitation threshold for positron impact that opens up at ˜0.3 eV below the Ps threshold, the present results strongly suggest that the incident positron is electronically exciting N2 and then binding to the excited N2 in a temporary resonance-like state from which the bound positron annihilates with a molecular electron. ^*Research supported by NSF Grant PHY 99-88093.[1] W.E.

    1994-12-01

    After 6 days of debate and 200 speakers during September 5-13, 1994, participants from 180 countries at the Cairo International Conference on Population and Development (ICPD) agreed on a strategy for curbing global population growth over the next 20 years. The objective was sustained economic growth and sustainable development. In his opening remarks, UN Secretary-General Boutros Boutros-Ghali said that the objective was to balance humanity and the environment with the means to sustain life, and that the efficacy of the world economic order depended to some extent on the ICPD. Participants were urged to use rigor, tolerance, and conscience in conference deliberations. Men and women should have the right and the means to choose their families' futures. The preamble stated that the ICPD would probably be the last opportunity in the twentieth century to address globally the issues relating to population and development. UN Population Fund Executive Director Nafis Sadik remarked that the ICPD had the potential to change the world. Egyptian President Mohamed Hosni Mubarak was elected president of the ICPD. Mubarak stated that solutions to population problems must go beyond demographic accounting and incorporate change in social, economic, and cultural conditions. Norway's Prime Minister Gro Harlem Brundtland stated that development in many countries never reached many women. She called it a hypocritical morality that allowed women to suffer and die from unwanted pregnancies, illegal abortions, and miserable living conditions. US Vice President Albert Gore called for comprehensive and holistic solutions. The essential features of social change would involve democracy, economic reform, low rates of inflation, low levels of corruption, sound environmental management, free and open markets, and access to developed country markets. Pakistan's Prime Minister Benazir urged the empowerment of women. Many expressed the concern about unsustainable consumption in industrialized

    Fasting has been recently discovered to improve overall health, but its beneficial effects in the presence of hepatic insufficiency have not been proven. The influence of fasting on the metabolism, immunological aspects, and oxidative stress of 40 male carbon tetrachloride (CCl4)-intoxicated Wistar rats was investigated in the present study. The rats were divided into four groups, including a placebo group, CCl4-intoxicated rats, which were injected subcutaneously with 1.0 ml/kg of CCl4 solution, a fasting group, which was fasted 12 h/day for 30 days, and a fourth group, which was injected with CCl4 and fasted. The metabolism, immunity, and oxidative stress improved in CCl4-intoxicated rats fasted for 12 h/day for 30 days, as evidenced in significant increase (p < 0.05) in total protein, globulin, immunoglobulin M (IgM) and IgG levels, and total antioxidant capacity. In contrast, significant decrease (p < 0.05) in blood glucose, total cholesterol, low-density lipoprotein-cholesterol, alanine aminotransferase, C-reactive protein, and malondialdehyde levels were observed. Compared with CCl4-intoxicated rats, significant differences in the albumin, triacylglycerol, high-density lipoprotein-cholesterol, very low-density lipoprotein-cholesterol, cardiovascular risk factor, calcium and magnesium levels were not detected. The results of the present study showed that fasting improved metabolism, immunity, and oxidative stress in CCl4-intoxicated rats. Thus, fasting during Ramadan is safe for patients with hepatic disorders, as the prophet Mohammed (S) said "Keep the fast, keep your health". © The Author(s) 2014.

  17. Assessing the attenuating effects of water vapor and airborne dust on solar energy resources in arid environments

    Solar power is one of the main forms of renewable energy on the planet, global interest in this form of energy is increasing with time and many projects around the world are ongoing to harvest solar energy, therefore an accurate assessment of solar potential is necessary. The accuracy of solar resource assessment reduces the risk associated with constructing large scale solar power plants in areas with poor solar irradiance. Interest in electricity from solar power plants is rapidly increasing in the Middle East. In the United Arab Emirates a target of 7% electricity production from renewable energy sources by the year 2020 has been set in Abu Dhabi. A 100MW CSP plant, Shams-1, will be operational by the end of 2012, which is to be followed by Shams-2 and Shams-3 plants. In Dubai a target of 5% electricity production from solar energy is set by 2030, work is undergoing in the Mohammed bin Rashid Al Maktoum Solar Park which should produce 10 MW by the end of 2013 and 1 GW by 2030. Thus location specific analysis of solar resources should be performed for candidate sites in the UAE. For a more accurate assessment, a special attention has to be given to the environmental and climatological conditions of the region. Water particles and other atmospheric aerosols can have a significant effect on the solar irradiance reaching the ground surface. Assessment of these effects over the UAE and their effect on solar resources has not been investigated thoroughly. Undertaking this assessment will help refine the exiting solar assessment models, and possible predictions of solar losses in dusty and humid conditions. Using the SEVIRI instrument on board the MSG satellite and NASA's AERONET to acquire the water vapor content in the atmosphere, and monitoring the time matched solar irradiance measurements will enable the analysis of the effects of water vapor in the atmosphere on the solar energy output.

    The Islamic Empire started its tumultuous and rapid expansion from the year 622 A.D. (the year of Mohammed's Egira). This rapid growth coincided with the epidemic spread of the bubonic plague in the Middle East. Although a first epidemic event had been documented in the year 570 A.D. (pre-Islamic phase), in the Arabic peninsula, classically according to M.W. Dols five severe episodes of plague sub-epidemics are considered in the middle-eastern geographic area: the first occurred in 627 and 628 A.D., the fifth in 716 A.D.. Anyway, we may state that at the onset of Islam the geographic region including Egypt, Palestine, Syria, Iraq, and Iran was involved by endemic plague. In their work, on the ground of a literature review, the Authors describe the characteristics of the epidemic phenomenon, and analyze the how the plague affected the interpretation of Prophet's Koran and Hadits. The passive attitude demonstrated by many Muslims during early Islam was not shared by all believers, since others moved towards a more soft approach, which included the behaviour of the so called moving aside , when the contagion was of concern. The epidemic plague significantly contributed to the weakening of the Eastern Roman Empire, and the rapid decline of the Persian Empire, while during the early expansion phases of Islam, it indirectly favoured the nomadic Arab tribes which, moving on desert or semi-desert territories, succeeded in escaping the contagion more easily. Subsequently, when the Arab population became sedentary, after occupying the conquered cities, this initial advantage was significantly reduced.

    A common challenge in bioinformatics is to identify short sub-sequences that are unique in a set of genomes or reference sequences, which can efficiently be achieved by k-mer (k consecutive nucleotides) counting. However, there are several areas that would benefit from a more stringent definition of "unique", requiring that these sub-sequences of length W differ by more than k mismatches (i.e. a Hamming distance greater than k) from any other sub-sequence, which we term the k-disjoint problem. Examples include finding sequences unique to a pathogen for probe-based infection diagnostics; reducing off-target hits for re-sequencing or genome editing; detecting sequence (e.g. phage or viral) insertions; and multiple substitution mutations. Since both sensitivity and specificity are critical, an exhaustive, yet efficient solution is desirable. We present microTaboo, a method that allows for efficient and extensive sequence mining of unique (k-disjoint) sequences of up to 100 nucleotides in length. On a number of simulated and real data sets ranging from microbe- to mammalian-size genomes, we show that microTaboo is able to efficiently find all sub-sequences of a specified length W that do not occur within a threshold of k mismatches in any other sub-sequence. We exemplify that microTaboo has many practical applications, including point substitution detection, sequence insertion detection, padlock probe target search, and candidate CRISPR target mining. microTaboo implements a solution to the k-disjoint problem in an alignment- and assembly free manner. microTaboo is available for Windows, Mac OS X, and Linux, running Java 7 and higher, under the GNU GPLv3 license, at: https://MohammedAlJaff.github.io/microTaboo.

    A serum-free, hormone-supplemented medium (SFHM) for maintaining neonatal rat heart cells in culture has been developed in this laboratory (Mohamed et al., 1983). Morphological assessment of heart cells grown in SFHM show it to be similar to commonly used serum-supplemented media. To quantitatively compare cell behavior in SFHM with serum-supplemented media, the activities of ten regulatory enzymes which represent four metabolic pathways were studied in heart cells cultured in SFHM. The enzyme activities which were measured included hexokinase, glucose-6-phosphate dehydrogenase, 6-phosphogluconate dehydrogenase, phosphofructokinase, pyruvate kinase, NAD+-linked sn-glycerol-3-phosphate dehydrogenase, malate dehydrogenase, NAD+-linked isocitrate dehydrogenase, NADH-cytochrome c reductase, and succinic cytochrome c reductase. Rat heart cells maintained in culture on SFHM are not only qualitatively and quantitatively similar to those maintained in serum-supplemented medium but also provide a more suitable model system for metabolic studies of neonatal cardiac tissue for several reasons: 1) many enzyme activities that may represent dedifferentiation are elevated by serum; 2) NAD-linked glycerol-3-phosphate dehydrogenase activity in cells maintained on SFHM is similar to the in vivo activity; 3) cells beat at or near the in vivo frequency and can be maintained 3 months on SFHM; 4) the SFHM is chemically defined and thus can be completely manipulated by the investigator. The effects of three concentrations of hydrocortisone (HC) (5,000 ng/ml, 50 micrograms/ml, 0 ng/ml) on heart cells cultured in SFHM supported our previous conclusion that function (beating) and growth (protein accumulation) are inversely related in cultured neonatal rat heart cells.

    Introduction This study aims to determine the Acinetobacter sp clinical isolates frequency and its antibiotic susceptibility pattern by comparing results obtained from the Intensive Care Units (ICUs) to that of other units at the Mohammed V Military Teaching Hospital in Rabat. Methods This is a retrospective study over a 2-years period where we collected all clinical isolates of Acinetobacter sp obtained from samples for infection diagnosis performed on hospitalized patients between 2012 to 2014. Results During the study period, 441 clinical and non-repetitive isolates of Acinetobacter sp were collected representing 6.94% of all bacterial clinical isolates (n = 6352) and 9.6% of Gram negative rods (n = 4569). More than a half of the isolates were from the ICUs and were obtained from 293 infected patients of which 65, 2% (191 cases) were males (sex ratio = 1.9) and the median age was 56 years (interquartile range: 42-68 years). Acinetobacter clinical isolates were obtained from respiratory samples (44.67%) followed by blood cultures (14.51%). The resistance to ciprofloxacin, ceftazidime, piperacillin / tazobactam, imipenem, amikacin, tobramycin, netilmicin, rifampicin and colistin was respectively 87%, 86%, 79%, 76%; 52%, 43%, 33% 32% and 1.7%. The difference in resistance between the ICUs and the other units was statistically significant (p <0.05) except for colistin, tetracycline and rifampicin. Conclusion This paper shows that solving the problem of prevalence and high rate of multidrug resistant Acinetobacter infection which represents a therapeutic impasse, requires the control of the hospital environment and optimizing hands hygiene and antibiotics use in the hospital.

    Nigeria was one of 3 polio-endemic countries before it was de-listed in September 2015 by the World Health Organization, following interruption of transmission of the poliovirus. During 2011-2014, Nigeria conducted serial polio seroprevalence surveys (SPS) in Kano Metropolitan Area, comprising 8 local government areas (LGAs) in Kano that is considered very high risk (VHR) for polio, to monitor performance of the polio eradication program and guide the program in the adoption of innovative strategies. Study subjects who resided in any of the 8 local government areas of Kano Metropolitan Area and satisfied age criteria were recruited from patients at Murtala Mohammed Specialist Hospital (Kano) for 3 seroprevalence surveys. The same methods were used to conduct each survey. The 2011 study showed seroprevalence values of 81%, 75%, and 73% for poliovirus types 1, 2, and 3, respectively, among infants aged 6-9 months age. Among children aged 36-47 months, seroprevalence values were greater (91%, 87%, and 85% for poliovirus types 1, 2, and 3, respectively).In 2013, the results showed that the seroprevalence was unexpectedly low among infants aged 6-9 months, remained high among children aged 36-47 months, and increased minimally among children aged 5-9 years and those aged 10-14 years. The baseline seroprevalence among infants aged 6-9 months in 2014 was better than that in 2013. The results from the polio seroprevalence surveys conducted in Kano Metropolitan Area in 2011, 2013, and 2014 served to assess the trends in immunity and program performance, as well as to guide the program, leading to various interventions being implemented with good effect, as evidenced by the reduction of poliovirus circulation in Kano. © 2016 World Health Organization; licensee Oxford Journals.

    The Sinai Peninsula is a triangular plateau lies in NE corner of Egypt, its head in the south at Ras Mohammed and its other sides between the Gulf of Aqaba and Gulf of Suez and the triangle base on the Mediterranean Sea. Sinai Peninsula is the most attractive region from the geological, geomorphological and environmental stand points of view because it displays a variety of simple and complex structural and landforms, (Abu Al-Izz,1971). In general, Sinai Peninsula reflects all geologic column of Egypt. Geomorphologically, Sinai Peninsula comprises many geomorphologic units such as mountains blocks, cliffs, isolated hills, wadies, hogbacks, questas, sand ridges, muddy and marshy lands, lakes and shorelines. This paper aims to define and measure geodiversity assessment index of the Sinai Peninsula as the quantitative variety of geological, topographical, geomorphological, hydrological and soil features. Some geodiversity indices maps for the above features produced for Sinai Peninsula were based on the methodology presented by (Pereira et al, 2012), it depends upon calculate of some geodiversity elements for overlay grid of the study area, which divided topographic, geological maps of the Sinai Peninsula with scale 1:500000 and satellite image (landsat 8, 27th October 2014, 12 bands, 30m). It divided into 743 squares (10x10 km), and some partial geodiversity indices such as geological, topographical, geomorphological, hydrological and soil indices were calculated by counting the number of each element inside each square, then the overall geodiversity index map produced by calculate the total number of all indices inside each square, the geodiversity index map were classified into some gradual categories by using isolines: very low, low, medium, high and very high.

We conducted this study to analyze the changes in the therapeutic strategy for AC in a surgical center in Tunisia after the Tokyo guidelines were published. Between January, 2005 and January, 2013, 649 patients underwent cholecystectomy for AC at the Department of Surgery, Mohamed Tahar Maamouri Hospital in Nabeul, Tunisia. The study period was subdivided into before (n = 192) and after (n = 457) the publication of the Tokyo guidelines, that is, prior to and including 2007, and from 2008 onward, respectively. We reviewed patient records retrospectively to collect demographic data, biochemical data, radiological findings, and postoperative outcomes. All these factors were compared between the groups. The duration of symptoms before surgery was significantly longer before 2008 (p = 0.018). ELC was significantly more frequent after 2008 (p = 0.001). Laparoscopic surgery was converted to open surgery in 16.1 % of patients before 2008 vs. 7.8 % of patients after 2008 (p = 0.02). There were no significant differences in bile duct injury or postoperative complications between the groups. The length of preoperative, postoperative, and total hospital stay was longer before 2008. ELC is a safe and effective therapeutic strategy for AC. The Tokyo guidelines resulted in a significant increase in the number of ELCs being performed and significantly reduced preoperative and total hospital stay without increasing intra- and postoperative complications. Importantly, ELC reduced medical costs, which is crucial for a country with limited resources, such as Tunisia.

    The dramatic asymmetry in terms of surface elevation, Cenozoic volcanisms, and earthquake activity across the Red Sea is an enigmatic issue in global tectonics, partially due to the unavailability of broadband seismic data on the African plate adjacent to the Red Sea. Here we report the first results from a receiver function study of the mantle transition zone (MTZ) discontinuities using data from the Egyptian National Seismic Network, and compare the resulting depths of the 410 and 660 km discontinuities (d410 and d660) with those observed on the Arabian side. Results using more than 6000 P-to-S receiver functions recorded at 49 broadband seismic stations in Egypt, Saudi Arabia and adjacent areas show that when the IASP91 Earth model is used for time-to-depth conversion, the resulting depth of the discontinuities increases systematically toward the axis of the Afro-Arabian Dome (AAD) from both the west and east. Relative to the westernmost area, the maximum depression of the 410-km discontinuity is about 30 km, and that of the 660-km discontinuity is about 45 km. Highly correlated d410 and d660 depths suggest that the observed apparent depth variations are mostly caused by lateral velocity anomalies in the upper mantle, while the 15 km additional depression of the d660 relative to the d410 requires either a colder-than-normal MTZ or the presence of water in the MTZ. We tested several models involving upper mantle and MTZ velocity anomalies and undulations of the MTZ discontinuities due to temperature anomalies and water content, and found that the observed systematic variations can best be explained by a model involving a hydrated MTZ and an upper-mantle low-velocity zone beneath the AAD (Mohamed et al., 2014, doi: 10.1093/gji/ggu284). Models invoking one or more mantle plumes originated from the MTZ or the lower-mantle beneath the study area are not consistent with the observations.

    The Emirates Mars Ultraviolet Spectrometer (EMUS) instrument is one of three science instruments to be carried on board the Emirate Mars Mission (EMM), the "Hope Probe". EMM is a United Arab Emirates' (UAE) mission to Mars launching in 2020 to explore the dynamics in the Martian atmosphere globally, while sampling on both diurnal and seasonal timescales. The EMUS instrument is a far-ultraviolet imaging spectrograph that measures emissions in the spectral range 100-170 nm. Using spacecraft motion, it will build up two-dimensional far-ultraviolet images of the Martian disk and near-space environment at several important wavelengths: Lyman beta atomic hydrogen emission (102.6 nm), Lyman alpha atomic hydrogen emission (121.6 nm), atomic oxygen emission (130.4 nm and 135.6 nm), and carbon monoxide fourth positive group band emission (140 nm-170 nm). Radiances at these wavelengths will be used to derive the column abundance of atomic oxygen, and carbon monoxide in the Martian thermosphere, and the density of atomic oxygen and atomic hydrogen in the Martian exosphere both with spatial and sub-seasonal variability. EMUS consists of a single telescope mirror feeding a Rowland circle imaging spectrograph capable of selectable spectral resolution (1.3 nm, 1.8 nm, or 5 nm) with a photon-counting and locating detector (provided by the Space Sciences Laboratory at the University of California, Berkeley). The EMUS spatial resolution of less than 300km on the disk is sufficient to characterize spatial variability in the Martian thermosphere (100-200 km altitude) and exosphere (>200 km altitude). The instrument is jointly developed by the Laboratory for Atmospheric and Space Physics (LASP) at the University of Colorado Boulder and Mohammed Bin Rashid Space Centre (MBRSC) in Dubai, UAE

    Les corps étrangers (CE) représentent une pathologie fréquemment rencontrée en pratique ORL d'urgence. Ils peuvent constituer une urgence vitale par leur aspect ou leur siège. Nous présentons le bilan de dix ans sur la prise en charge des CE de la sphère ORL avec une revue de la littérature. Il s'agit d'une étude rétrospective entre Janvier 2004 et Décembre 2013, incluant tous les cas de CE des voies aéro-digestives supérieures et auriculaires colligés dans le service d'ORL au CHU Mohammed VI de Marrakech au Maroc. Sur les 1317 cas de CE de la sphère ORL colligés durant cette période, 80,48% concernaient les enfants. Le sex-ratio était de 1,5. L’âge moyen était de 12,92 ans. Les CE œsophagiens étaient les plus fréquents (47,53%). Les complications ont été rencontrées dans 11,69% des cas. Les CE dans la sphère ORL restent fréquents en pratique quotidienne surtout chez les enfants. Leur prise en charge nécessite une intervention rapide avec un matériel adapté et des médecins entrainés. La prévention reste la meilleure solution. PMID:26516392

    Background. Nigeria was one of 3 polio-endemic countries before it was de-listed in September 2015 by the World Health Organization, following interruption of transmission of the poliovirus. During 2011–2014, Nigeria conducted serial polio seroprevalence surveys (SPS) in Kano Metropolitan Area, comprising 8 local government areas (LGAs) in Kano that is considered very high risk (VHR) for polio, to monitor performance of the polio eradication program and guide the program in the adoption of innovative strategies. Methods. Study subjects who resided in any of the 8 local government areas of Kano Metropolitan Area and satisfied age criteria were recruited from patients at Murtala Mohammed Specialist Hospital (Kano) for 3 seroprevalence surveys. The same methods were used to conduct each survey. Results. The 2011 study showed seroprevalence values of 81%, 75%, and 73% for poliovirus types 1, 2, and 3, respectively, among infants aged 6–9 months age. Among children aged 36–47 months, seroprevalence values were greater (91%, 87%, and 85% for poliovirus types 1, 2, and 3, respectively). In 2013, the results showed that the seroprevalence was unexpectedly low among infants aged 6–9 months, remained high among children aged 36–47 months, and increased minimally among children aged 5–9 years and those aged 10–14 years. The baseline seroprevalence among infants aged 6–9 months in 2014 was better than that in 2013. Conclusions. The results from the polio seroprevalence surveys conducted in Kano Metropolitan Area in 2011, 2013, and 2014 served to assess the trends in immunity and program performance, as well as to guide the program, leading to various interventions being implemented with good effect, as evidenced by the reduction of poliovirus circulation in Kano.

    At present most of II-VI semiconductor based solar cells use the CdTe material as an absorber film. The simulation of its performance is realized by means of various numerical modelling programs. We have modelled a solar cell based on zinc telluride (ZnTe) thin film as absorber in substitution to the CdTe material, which contains the cadmium element known by its toxicity. The performance of such photovoltaic device has been numerically simulated and the thickness of the absorber layer has been optimized to give the optimal conversion efficiency. A photovoltaic device consisting of a ZnTe layer as absorber, CdS as the buffer layer and ZnO as a window layer was modelled through Solar Cell Capacitance Simulator Software. Dark and illuminated I-V characteristics and the results for different output parameters of ZnO/CdS/ZnTe solar cell were analyzed. The effect of ZnTe absorber thickness on different main working parameters such as: open-circuit voltage Voc, short-circuit current density Jsc, fill factor FF, photovoltaic conversion efficiency η was intensely studied in order to optimize ZnTe film thickness. This study reveals that increasing the thickness of ZnTe absorber layer results in higher efficiency until a maximum value and then decreases slightly. This maximum was found to be 10% at ZnTe optimum thickness close to 2 µm.

    Arterial hypertensions (HTA) of endocrine origin are a rare cause of hypertension; HTA overall prevalence don't exceed 4% of hypertensive patients. Research interest in endocrine HTA is due to the severity of some life-threatening, potentially curable and reversible forms of HTA. The aim of our study was to determine the clinical, paraclinical, etiological and therapeutic profile of secondary HTA of endocrine origin in patients treated in endocrinology department at the University Hospital Mohamed VI in Marrakech. We conducted a prospective, descriptive study spanned 4 years, enrolling 45 patients with endocrine HTA. The average age was 44.89 years, with a clear predominance of women (sex ratio 0.49). Etiology of endocrine HTA was dominated by pheochromocytoma (17 cases), hypercorticism (11 cases) and acromegaly (8 cases). HTA were paroxysmal in 24.4%. HTA were immediately classified as grade 3 severe in 40% of cases. HTA were complicated by heart disease in 24% of cases and by renal disease in 20% of cases. Curative treatment cleared up HTA in 60% of cases (27 cases). The diagnosis of secondary endocrine HTA is sometimes difficult because of the lack of clinical specificity. It is not unusual for HTA to be the only manifestation of the disease. In our study we noted the paroxysmal and severe nature of HTA. The potentially curable nature of HTA in more than two thirds of cases, demostrates the importance of early diagnosis of each severe HTA resistant to treatment or in the presence of suggestive clinical, biological or radiological signs.

    Study Objective: To test the hypothesis that respiratory event duration exhibits an endogenous circadian rhythm. Design: Within-subject and between-subjects. Settings: Inpatient intensive physiologic monitoring unit at the Brigham and Women's Hospital. Participants: Seven subjects with moderate/severe sleep apnea and four controls, age 48 (SD = 12) years, 7 males. Interventions: Subjects completed a 5-day inpatient protocol in dim light. Polysomnography was recorded during an initial control 8-h night scheduled at the usual sleep time, then through 10 recurrent cycles of 2 h 40 min sleep and 2 h 40 min wake evenly distributed across all circadian phases, and finally during another 8-h control sleep period. Measurements and Results: Event durations, desaturations, and apnea-hypopnea index for each sleep opportunity were assessed according to circadian phase (derived from salivary melatonin), time into sleep, and sleep stage. Average respiratory event durations in NREM sleep significantly lengthened across both control nights (21.9 to 28.2 sec and 23.7 to 30.2 sec, respectively). During the circadian protocol, event duration in NREM increased across the circadian phases that corresponded to the usual sleep period, accounting for > 50% of the increase across normal 8-h control nights. AHI and desaturations were also rhythmic: AHI was highest in the biological day while desaturations were greatest in the biological night. Conclusions: The endogenous circadian system plays an important role in the prolongation of respiratory events across the night, and might provide a novel therapeutic target for modulating sleep apnea.

    Salinivibrio genus is included in the family Vibrionaceae and up to now is constituted by only five members. All the species are moderately halophilic bacteria found in salted meats, brines, and several hypersaline environments. Halophilic microorganisms are good sources of biomolecules, such as proteases, that have a great industrial interest as demonstrated by recent studies. All these bacteria possess on their outer membrane amphiphilic molecules named lipopolysaccharides, which are of great interest because of their involvement in the mechanisms of interaction between the microbial life and environmental factors. A novel haloalkaliphilic, facultative anaerobic and Gram-negative Salinivibrio-like microorganism, named S. sharmensis strain BAG(T), was recovered from a saline lake in Ras Mohammed Park (Egypt). The aim of this work is the isolation and structural characterization of the core oligosaccharidic fraction of the lipopolysaccharide from this bacterium. By means of HPAEC-PAD we were able to purify two glycoforms, fully depicted by ESI FT-ICR mass spectrometry, chemical analysis, and NMR spectroscopy. Like other haloalkaliphilic bacteria, the core region was found to be characterized by the presence of several negatively charged residues, such as uronic acids. All the data contributed to give the following structure α-D-Glc-(1-->4)-β-D-GalNAc-(1--4)-β-D-Glc1-->4α-D-GlcA-(1-->2)-α-L,D-Hep-(1-->3)-α-D,D-Hep-(1-->5)-α-D-Kdo4P-(2-->6)-LipidA2<--1β-D-GlcA.

    In arid and semi-arid areas, low soil fertility and water deficit considerably limit crop production. The use of sewage sludge as an organic amendment could contribute to the improvement of soil fertility and hence the agronomic production. The study aims to highlight the behaviour of durum wheat to the application of sewage sludge associated with water stress. The assessment focused on morphophysiological parameters of the wheat plant and yield. Under greenhouse conditions, the variety Mohamed Ben Bachir was treated by four water stress levels (100 %, 80 %, 50 % and 30 %). Each stress level comprised five fertilizer treatments: 20, 50 and 100 t/ha of dry sludge, 35 kg/ha of urea, and a control with no fertilization. Results revealed a significant loss in water content and chlorophyll a in leaves. Water stress negatively affected the development of wheat plants by reducing significantly seed yield, leaf area and biomass produced. Plant’s responses to water stress manifested by an accumulation of proline and a decrease in total phosphorus. However, the increasing doses of sewage sludge limited the effect of water stress. Our findings showed an increase in the amount of chlorophyll pigments, leaf area, total phosphorus, biomass and yield. In addition, excessive accumulation of proline (1.11 ± 1.03 µg/g DM) was recorded as a result of the high concentration of sludge (100 t/ha DM). The application of sewage sludge is beneficial for the wheat crop, but the high accumulation of proline in plants treated with high dose of sludge suggests to properly consider this fact. The application of sludge should be used with caution in soils where water is limited. Because the combined effect of these two factors could result in a fatal osmotic stress to crop development.

    Before arrival into doctor's clinic, child might have acquired an impression of a clinical environment and doctor's appearance. Different kind of doctor's attire may evoke different reactions. By understanding children and parent's perception and preferences about dentist's attire, a suitable dress code could be adopted to establish good rapport with children. To evaluate children and parental perceptions and preferences towards dentist attire. A questionnaire designed with series of photographs of male and female dental students in different attires was responded by 150 parents aged 29 to 63 years and 150 children aged 9 to 13 years. Seventy percent of children participants (n = 104) and 42% of parents participants (n = 63) favored the traditional white coat attire. However, 58% parents (n = 87) significantly preferred non-white coat attires in comparison to 30% of children (n = 46) (χ(2) = 21.61, p < 0.001). No statistical significant difference was noted among the children and the parents, both favoring the use of protective wear (χ(2) = 0.99 p > 0.05), no-significant association was found between parents and children response to white coat (χ(2) = 0.39, p = 0.53). A highly significant difference was found between the male participants, who favored the male dentist and female participants preferring the female dentist (χ(2) = 47.16, p < 0.001). Our study attempted to rule out the stereotyped concept of 'white coat fear' among children, both children and parents favored traditional white coat attire, contrary to popular misconception 'white coat syndrome'. However, use of child friendly attires could be useful in anxious children for better practice management.

    This review summarizes the current status of the small incision lenticule extraction (SMILE) procedure. Following the early work by Sekundo et al. and Shah et al., SMILE has become increasingly popular. The accuracy of the creation of the lenticule with the VisuMax femtosecond laser (Carl Zeiss Meditec) has been verified using very high-frequency (VHF) digital ultrasound and optical coherence tomography (OCT). Visual and refractive outcomes have been shown to be similar to those achieved with laser in situ keratomileusis (LASIK), notably in a large population reported by Hjortdal, Vestergaard et al. Safety in terms of the change in corrected distance visual acuity (CDVA) has also been shown to be similar to LASIK. It was expected that there would be less postoperative dry eye after SMILE compared to LASIK because the anterior stroma is disturbed only by the small incision, meaning that the anterior corneal nerves should be less affected. A number of studies have demonstrated a lower reduction and faster recovery of corneal sensation after SMILE than LASIK. Some studies have also used confocal microscopy to demonstrate a lower decrease in subbasal nerve fiber density after SMILE than LASIK. The potential biomechanical advantages of SMILE have been modeled by Reinstein et al. based on the non-linearity of tensile strength through the stroma. Studies have reported a similar change in Ocular Response Analyzer (Reichert) parameters after SMILE and LASIK, however, these have previously been shown to be unreliable as a representation of corneal biomechanics. Retreatment options after SMILE are discussed. Tissue addition applications of the SMILE procedure are also discussed including the potential for cryo-preservation of the lenticule for later reimplantation (Mohamed-Noriega, Angunawela, Lim et al.), and a new procedure referred to as endokeratophakia in which a myopic SMILE lenticule is implanted into a hyperopic patient (Pradhan et al.).

    To investigate how the perceptions and behaviour of visitors to coral reefs are influenced by their prior experience and knowledge of marine life, a questionnaire-based study was undertaken at sites in the Ras Mohammed National Park and at Sharm El Sheikh, South Sinai, Egypt. It was evident that over the 10-20 years during which these reefs have deteriorated (mainly due to reef-flat trampling), there have been interrelated shifts in the nature of visitors making use of them. First, there has been a shift from experienced divers and snorkellers to inexperienced snorkellers and non-snorkellers with a poorer knowledge of reef biology. Second, there has been a shift in the predominant nationalities of visitors, from German and British, through Italian, to Russian. More recent user groups both stated and showed that they had less experience of snorkelling; they also showed less knowledge of marine life and less interest in learning about it. Visitor perceptions of both the state of the marine life on the reefs and the acceptability of current visitor numbers also varied between groups. More recent visitor groups and visitors with less knowledge were more satisfied with reef health. In general, however, visitor perceptions of reef health did not correlate well with actual reef conditions, probably because more experienced visitors preferred less impacted sites with which they were nevertheless less satisfied than inexperienced visitors at heavily impacted sites. More recent visitor groups were also less bothered by crowding on the shore or in the water. Consequently, the apparent “social carrying capacity” of sites seems to be increasing to a level well above the likely “ecological carrying capacity”.

    Ultrafast, time-resolved investigations of acid-base neutralization reactions have recently been performed using systems containing the photoacid 8-hydroxypyrene-1,3,6-trisulfonic acid trisodium salt (HPTS) and various Brønsted bases. Two conflicting neutralization mechanisms have been formulated by Mohammed et al. [Science 310, 83 (2005)] and Siwick et al. [J. Am. Chem. Soc. 129, 13412 (2007)] for the same acid-base system. Herein an ab initio molecular dynamics based computational model is formulated, which is able to investigate the validity of the proposed mechanisms in the general context of ground-state acid-base neutralization reactions. Our approach consists of using 2,4,6-tricyanophenol (exp. pKa≅1) as a model for excited-state HPTS∗ (pKa≅1.4) and carboxylate ions for the accepting base. We employ our recently proposed dipole-field/quantum mechanics (QM) treatment [P. Maurer and R. Iftimie, J. Chem. Phys. 132, 074112 (2010)] of the proton donor and acceptor molecules. This approach allows one to tune the free energy of neutralization to any desired value as well as model initial nonequilibrium hydration effects caused by a sudden increase in acidity, making it possible to achieve a more realistic comparison with experimental data than could be obtained via a full-QM treatment of the entire system. It is demonstrated that the dipole-field/QM model reproduces correctly key properties of the 2,4,6-tricyanophenol acid molecule including gas-phase proton dissociation energies and dipole moments, and condensed-phase hydration structure and pKa values.

    The development of innovative systems of heat storage is imperative to improve the efficiency of the existing systems used in the thermal solar energy applications. Several techniques were developed and realized in this context. The technology of the sand fluidized bed (sandTES) offers a promising alternative to the current state-of-the-art of the heat storage systems, such as fixed bed using a storage materials, as sand, ceramic, and stones, etc. Indeed, the use of the fluidization technique allows an effective heat transfer to the solid particles. With the sand, an important capacity of storage is obtained by an economic and ecological material [N. Mahfoudi, A. Moummi, M. El Ganaoui, Appl. Mech. Mater. 621, 214 (2014); N. Mahfoudi, A. Khachkouch, A. Moummi B. Benhaoua, M. El Ganaoui, Mech. Ind. 16, 411 (2015); N. Mahfoudi, A. Moummi, M. El Ganaoui, F. Mnasri, K.M. Aboudou, 3e Colloque internationale Francophone d"énergétique et mécanique, Comores, 2014, p. 91]. This paper presents a CFD simulation of the hydrodynamics and the thermal transient behavior of a fluidized bed reactor of sand, to determine the characteristics of storage. The simulation shows a symmetry breaking that occurs and gave way to chaotic transient generation of bubble formation after 3 s. Furthermore, the predicted average temperature of the solid phase (sand) increases gradually versus the time with a gain of 1 °C in an interval of 10 s.

All of these individuals contributed strongly to Workshop, with the result that ARM’s involvement in and contribution to AMMA was enhanced with respect to land surface, water cycle, aerosol, and radiation issues. Also, the Workshop gave these participants early exposure to ARM’s 2007 CLASIC Campaign over the U.S. Southern Great Plains, which is addressing parts of the same problem complex. The following eight individuals were fully funded (complete airfare, accommodations, registration, meals) to participate in the Workshop -- Dr. Aiguo Dai (NCAR, USA), Dr. Adamou Ousmane Manga (University of Niamey, Niger), Professor Abdelkrim Ben Mohamed (University of Niamey, Niger), Dr. Gary Robinson (University of Reading, UK), Dr. Amadou Gaye (University of Dakar, Senegal), Dr. Anne Jefferson (NOAA, USA), Dr. Aondover Tarhule (University of Oklahoma, USA), and Dr. Sally McFarlane (Pacific Northwest National Laboratory, USA). Partial funding also was provided for Professor Peter Lamb (University of Oklahoma, USA). To deepen the involvement of ARM in AMMA, the grant also paid for participation in the AMMA Special Observing Period in Niamey during August (Professor Peter J. Lamb) and in a follow-up Workshop at Méteo France (Toulouse) in November (Dr. Zeinabou Mindaodou Souley, University of Niamey, Niger; Professor Peter J. Lamb). When he was in Niamey for 11 days in August, Professor Lamb had considerable involvement with the ARM Mobile Facility there. I am confident that the participation of the above individuals in the two AMMA Workshops and the AMMA Special Observing Period strengthened the ARM Program’s contribution to AMMA, increased the associated international attention on ARM, and provided a bridge to the ARM CLASIC Campaign

    In Egypt, television contributed decisively to the rise in contraceptive prevalence from 37.8% in 1988 to 47.1% in 1992. The 1992 Egyptian Demographic and Health Survey (EDHS-92) showed that 73% of men and 71% of women cited television as their first source of information about family planning. Factors that account for the success of television in spreading the family planning message are: full political and religious support, strategic planning, innovative programming, a no-nonsense approach to providing family planning information, and action by an array of public, private voluntary and commercial family planning organizations. The State Information Service Information Education and Communication Center (SIS/IEC Center) within the Ministry of Information produced appropriate messages and programs to promote family planning acceptance and practice. Television was selected as a mainstay of the IEC program for family planning. Between 1988 and 1992 SIS had produced over 30 TV spots, airing them four times daily, and produced several prime-time TV dramas. In a television broadcast in the late 1980s, Mufti Mohamed Sayed Tantawe issued a decree supporting family planning. The decree induced clergymen and other opinion leaders in the villages to open advocacy of family planning. Local outreach activities were especially effective in promoting family planning acceptance among local influential men. A high-quality seventeen episode drama entitled, And the Nile Flows On, met with immediate critical success. The drama tackled the issues of the religious acceptability of family planning, the preference of sons over daughters, and the risk of closely-spaced births. Subsequently, 57% of viewers expressed their intention to visit a clinic as compared to 37% of nonviewers. The 1992 EDHS showed that 70.3% of women identified television as their first source of information regarding family planning. Relatives and friends were next at 21.7%.

    To investigate how the perceptions and behaviour of visitors to coral reefs are influenced by their prior experience and knowledge of marine life, a questionnaire-based study was undertaken at sites in the Ras Mohammed National Park and at Sharm El Sheikh, South Sinai, Egypt. It was evident that over the 10-20 years during which these reefs have deteriorated (mainly due to reef-flat trampling), there have been interrelated shifts in the nature of visitors making use of them. First, there has been a shift from experienced divers and snorkellers to inexperienced snorkellers and non-snorkellers with a poorer knowledge of reef biology. Second, there has been a shift in the predominant nationalities of visitors, from German and British, through Italian, to Russian. More recent user groups both stated and showed that they had less experience of snorkelling; they also showed less knowledge of marine life and less interest in learning about it. Visitor perceptions of both the state of the marine life on the reefs and the acceptability of current visitor numbers also varied between groups. More recent visitor groups and visitors with less knowledge were more satisfied with reef health. In general, however, visitor perceptions of reef health did not correlate well with actual reef conditions, probably because more experienced visitors preferred less impacted sites with which they were nevertheless less satisfied than inexperienced visitors at heavily impacted sites. More recent visitor groups were also less bothered by crowding on the shore or in the water. Consequently, the apparent "social carrying capacity" of sites seems to be increasing to a level well above the likely "ecological carrying capacity".

    Departing from the definition of the stigmata as the wounds which, temporarely or permanently, manifest in some cases of extasy following a selected model of suffering (Jesus, Mohammed etc.), the present paper analyzes the phenomenology of stigmatization on several most famous historical and actual examples: Francis of Assisi, as the first stigmatized at all; Catherine of Siena, the only one beside Francis whose stigmata have been recognized by the Church as supernatural; Rita of Cascia (14th c.); Marie de Mörl (1812-1868) from Tirol; the Belgian Louise Lateau (1850-1883); Izabele Hendricks (1844-1874), who died from bleeding; Gemma Galgani (1878-1903), who presented stigmata and the traces of flagellation; the Bavarian Therese Neumann (1898-1962), of whom probabely the most has been written; the popular mendicant father Pio from Pietrelcina (1887-1968); Giulio Massa (b. 1970) from Montecorvino near Salerno, already known as the "Father Pio of the 21st century," who speeks out in Aramaic during extasy; and the first Croatian stigmatized, Zlatko Sudac (b. 1971). Considering some older and more recent interpretations of the stigmata, a more precise definition of that phenomenon is suggested. Acording to it, the stigmata might be considered spontaneous, isolated cases of the localized deautonomization of influence upon superficial blood vessels, mediated by altered consciousness. Pointed out are the potential enormous benefits which medicine might provide by finding out the regularity and methods by which that phenomenon would be initiated in a controlled way, at full consciousness, without external help and at any place on the body.

    Ultrafast, time-resolved investigations of acid-base neutralization reactions have recently been performed using systems containing the photoacid 8-hydroxypyrene-1,3,6-trisulfonic acid trisodium salt (HPTS) and various Bronsted bases. Two conflicting neutralization mechanisms have been formulated by Mohammed et al. [Science 310, 83 (2005)] and Siwick et al. [J. Am. Chem. Soc. 129, 13412 (2007)] for the same acid-base system. Herein an ab initio molecular dynamics based computational model is formulated, which is able to investigate the validity of the proposed mechanisms in the general context of ground-state acid-base neutralization reactions. Our approach consists of using 2,4,6-tricyanophenol (exp. pKa congruent with 1) as a model for excited-state HPTS( *) (pKa congruent with 1.4) and carboxylate ions for the accepting base. We employ our recently proposed dipole-field/quantum mechanics (QM) treatment [P. Maurer and R. Iftimie, J. Chem. Phys. 132, 074112 (2010)] of the proton donor and acceptor molecules. This approach allows one to tune the free energy of neutralization to any desired value as well as model initial nonequilibrium hydration effects caused by a sudden increase in acidity, making it possible to achieve a more realistic comparison with experimental data than could be obtained via a full-QM treatment of the entire system. It is demonstrated that the dipole-field/QM model reproduces correctly key properties of the 2,4,6-tricyanophenol acid molecule including gas-phase proton dissociation energies and dipole moments, and condensed-phase hydration structure and pKa values.

    In arid and semi-arid areas, low soil fertility and water deficit considerably limit crop production. The use of sewage sludge as an organic amendment could contribute to the improvement of soil fertility and hence the agronomic production. The study aims to highlight the behaviour of durum wheat to the application of sewage sludge associated with water stress. The assessment focused on morphophysiological parameters of the wheat plant and yield. Under greenhouse conditions, the variety Mohamed Ben Bachir was treated by four water stress levels (100 %, 80 %, 50 % and 30 %). Each stress level comprised five fertilizer treatments: 20, 50 and 100 t/ha of dry sludge, 35 kg/ha of urea, and a control with no fertilization. Results revealed a significant loss in water content and chlorophyll a in leaves. Water stress negatively affected the development of wheat plants by reducing significantly seed yield, leaf area and biomass produced. Plant's responses to water stress manifested by an accumulation of proline and a decrease in total phosphorus. However, the increasing doses of sewage sludge limited the effect of water stress. Our findings showed an increase in the amount of chlorophyll pigments, leaf area, total phosphorus, biomass and yield. In addition, excessive accumulation of proline (1.11 ± 1.03 µg/g DM) was recorded as a result of the high concentration of sludge (100 t/ha DM). The application of sewage sludge is beneficial for the wheat crop, but the high accumulation of proline in plants treated with high dose of sludge suggests to properly consider this fact. The application of sludge should be used with caution in soils where water is limited. Because the combined effect of these two factors could result in a fatal osmotic stress to crop development.

    Since the application of technical medicine by the Greeks, modern neurology has been based on a body of knowledge and cultural heritage from ancient times. In this paper we review the contribution made by Al Andalus to neuroscience during the Middle Ages and its repercussions on modern neurology. Following the death of Mohammed in the vii century AD, Islam enjoyed one of the most spectacular periods of expansion in the history of mankind. Occupation of the cities of Alexandria and Gundishapur put the Arabs into contact with original Greco Latin manuscripts, which were assimilated and divulged by Islamic scientists in the middle eastern caliphates of Damascus and Bagdad as well as the western caliphates of Al Andalus (Spain) and Kairwan (Tunis). This classical hippocratico galenico medicine was refashioned into the so called arabized galenism, which markedly influenced the Scholastics and the cultured world of the lower Middle Ages and became the basis of European medicine until well into the Renaissance period. There was a first Spanish cultural Renaissance in Al Andalus during the ix xii centuries, which led to a flowering unheard of in the Middle Ages before then. Andalusian doctors made major contributions to the body of knowledge about neuroscience and developed major philosophical concepts of human understanding. Thus, Abulcasis (936 1013), the father of modern surgery, developed material and technical designs which are still used in neurosurgery. Averroes suggested the existence of Parkinson s syndrome and attributed photoreceptor properties to the retina. Avenzoar described meningitis, intracranial thrombophlebitis, mediastinal tumours and made contributions to modern neuropharmacology. Maimonides wrote about neuropsychiatric disorders and described rabies and belladonna intoxication. Aside from the political, religious and cultural differences between Al Andalus and the Christian kingdoms of the Iberian peninsula, the historical Andalusian period (711 1492

    Emirates Mars Infrared Spectrometer (EMIRS) instrument is one of three scientific instruments aboard the Emirate Mars Mission (EMM), with the name of "Hope". EMM is United Arab Emirates' (UAE) mission to be launched in 2020, with the aim of exploring the dynamics of the atmosphere of Mars on a global scale with sampling on a diurnal and sub-seasonal time-scales. EMM has three scientific instruments selected to provide an improved understanding of circulation and weather in the Martian lower atmosphere as well as the thermosphere and exosphere. The EMIRS instrument is an interferometric thermal infrared spectrometer that is jointly developed by Arizona State University (ASU) and Mohammed Bin Rashid Space Centre (MBRSC), Dubai, UAE. It builds on a long heritage of thermal infrared spectrometers designed, built, and managed, by ASU's Mars Space Flight Facility, including the Thermal Emission Spectrometer (TES), Miniature Thermal Emission Spectrometer (Mini-TES), and the OSIRIS-REx Thermal Emission Spectrometer (OTES). EMIRS operates in the 6-40+ μm range with 5 cm-1 spectral sampling, enabled by a Chemical Vapor-Deposited (CVD) diamond beam splitter and state of the art electronics. This instrument utilizes a 3×3 line array detector and a scan mirror to make high-precision infrared radiance measurements over most of the Martian hemisphere. The EMIRS instrument is optimized to capture the integrated, lower-middle atmosphere dynamics over a Martian hemisphere, using a scan-mirror to make 60 global images per week ( 20 images per orbit) at a resolution of 100-300 km/pixel while requiring no special spacecraft maneuvers.

    Diabetic nephropathy is the primary cause of chronic kidney disease and is associated with increased cardiovascular mortality. Cigarette smoking is probably the most complex and the least understood among the risk factors for chronic kidney disease and cardiovascular disease in diabetic patients. The aim of this study was to determine the impact of smoking on progression of nephropathy and cardiovascular disease in type 2 diabetic patients with albuminuria and those without albuminuria. Methods: This is a prospective study. The Ethics Committee of Morocco’s Mohammed V University in Rabat approved the study protocol. Inclusion criteria targeted patients who were type 2 diabetics and who had nephrology follow up for at least 36 months. Results: A total of 671 cases of T2D were included. Mean age of all patients was 65 ± 11 years and 12.1% were smokers. There was no statistically significant difference between T2D patients with albuminuria according to absence of presence of smoking at the time of enrollment, at 1 year and 3 years of follow-up, concerning the median albumin excretion rate (mg/day): 98 [56-281] vs. 124 [56-323] (p=0.59); 98 [56-281] vs. 124 [56-323] (p=0.15) and 98 [56-281] vs. 124 [56-323] (p=0.52) respectively. There was a statistically significant difference between T2D patients with albuminuria according to absence or presence of smoking at the time of enrollment and the end of follow-up, concerning cardiovascular events: 56 (12.3%) vs. 19 (28.4%) (p<0.001) and 66 (14.5%) vs. 19 (28.4%) (p=0.004) respectively. Conclusion: Smoking remains one of the most important modifiable risk factors for progression of renal and cardiovascular disease in diabetic patients, thus adding to the burden of morbimortality.

    Radio absorptivity data for planetary atmospheres obtained from spacecraft radio occultation experiments, entry probe radio signal absorption measurements, and earth- based or spacecraft-based radio astronomical (emission) observations can be used to infer abundances of microwave absorbing constituents in those atmospheres, as long as reliable information regarding the microwave absorbing properties of potential constituents is available. The use of theoretically-derived microwave absorption properties for such atmospheric constituents, or the use of laboratory measurements of such properties taken under environmental conditions that are significantly different than those of the planetary atmosphere being studied, often leads to significant misinterpretation of available opacity data. For example, new laboratory measurements completed recently by Mohammed and Steffes (2003 and 2004) under this grant (NAG5-12122,5/1/02-4/30/05), have shown that the millimeter-wavelength opacities from both gaseous phosphine (PH3) and gaseous ammonia ("3) under simulated conditions for the outer planets vary significantly from that predicted by theory over a wide range of temperatures and pressures. These results have directly impacted planning and scientific goals for study of Saturn's atmosphere with the Cassini Radio Science Experiment, as discussed below. The recognition of the need to make such laboratory measurements of simulated planetary atmospheres over a range of temperatures and pressures which correspond to the altitudes probed by both radio occultation experiments and radio astronomical observations, and over a range of frequencies which correspond to those used in both spacecraft entry probe and orbiter (or flyby) radio occultation experiments and radio astronomical observations, has led to the development of a facility at Georgia Tech which is capable of making such measurements. It has been the goal of this investigation to conduct such measurements and to apply the

    Sexual and reproductive rights of women are essential components of human rights. They should never be transferred, renounced or denied for any reason based on race, religion, origin, political opinion or economic conditions. Women have the right to the highest attainable standard of health care for all aspects of their reproductive and sexual health (RSH). The principle of autonomy emphasizes the important role of women in the decision-making. Choices of women in reproduction, after providing evidence based information, should be respected. Risks, benefits and alternatives should be clearly explained before they make their free informed consent. Justice requires that all be treated with equal standard and have equal access to their health needs without discrimination or coercion. When resources are limited there is tension between the principle of justice and utility. Islamic perspectives of bioethics are influenced by primary Sharia namely the Holy Quran, authenticated traditions and saying of the Profit Mohamed (PBUH), Igmaa and Kias (analogy). All the contemporary ethical principles are emphasized in Islamic Shariaa, thus these principles should be observed when providing reproductive and sexual health services for Muslim families or communities. The Family is the basic unit in Islam. Safe motherhood, family planning, and quality reproductive and sexual health information and services and assisted reproductive technology are all encouraged within the frame of marriage. While the Shiaa sect permits egg donation, and surrogacy the Sunni sect forbids a third party contribution to reproduction. Harmful practices in RSH as FGM, child marriage and adolescent pregnancy are prohibited in Islam. Conscientious objection to treatment should not refrain the physician from appropriate referral.

    The Emirates eXploration Imager (EXI) instrument is one of three scientific instruments abroad the Emirate Mars Mission (EMM) spacecraft, "Hope". The planned launch window opens in the summer of 2020, with the goal of this United Arab Emirates (UAE) mission to explore the dynamics of the Martian atmosphere through global spatial sampling which includes both diurnal and seasonal timescales. A particular focus of the mission is the improvement of our understanding of the global circulation in the lower atmosphere and the connections to the upward transport of energy of the escaping atmospheric particles from the upper atmosphere. This will be accomplished using three unique and complementary scientific instruments. The subject of this presentation, EXI, is a multi-band camera capable of taking 12 megapixel images, which translates to a spatial resolution of better than 8 km with a well calibrated radiometric performance. EXI uses a selector wheel mechanism consisting of 6 discrete bandpass filters to sample the optical spectral region: 3 UV bands and 3 visible (RGB) bands. Atmospheric characterization will involve the retrieval of the ice optical depth using the 300-340 nm band, the dust optical depth in the 205-235nm range, and the column abundance of ozone with a band covering 245-275 nm. Radiometric fidelity is optimized while simplifying the optical design by separating the UV and VIS optical paths. The instrument is being developed jointly by the Laboratory for Atmospheric and Space Physics (LASP), University of California, Boulder, USA, and Mohammed Bin Rashid Space Centre (MBRSC), Dubai, UAE.

    Escherichia coli (E. coli) is the most commonly isolated bacteria in human pathology. In Morocco the data concerning the nature and the rates of antibiotic resistance of E. coli in both hospitals and city environment remains relatively poor and needs further investigations. During a 16 months period, E. coli isolates were collected from different culture specimens received in the Bacteriology Department of the Military teaching Hospital Mohammed-V-Rabat for routine diagnostic purposes. E. coli isolates were identified and their antimicrobial susceptibility pattern was determined. A total of 1369 E. coli isolates comprising 33% (1369/4110) of culture-positive samples were consecutively collected. Isolates of E. coli were, in 40.5% (554/1369) of cases from hospitalized patients and in 59.5% (815/1369) of cases from outpatients. Urine isolates represented 82% (1123/1369) of the cases. High rates of resistance were found for amoxicillin (42.5%), cefalotin (30.4%), norfoloxacin (29.9%) and sulfamethoxazole (37.7%). The detection rate of ESBL was 6.1% (85/1369). In hospitalized patients 11.9% of the isolates of E. coli (66/554) had an ESBL phenotype while in outpatients cases only 2.3% of isolates of E. coli (19/815) had this phenotype. Our findings suggest that more judicious use of antibiotics is needed especially in probabilistic treatment. The emergence of ESBL in the Moroccan cities is an indicator of the severity of this problem that is not limited to health care facilities.

  14. To mutilate in the name of Jehovah or Allah: legitimization of male and female circumcision.

    Female circumcison is practised in Sudan, Somalia, Egypt and a few other Arab and Muslim countries. It has triggered a passionate public debate in the West. This debate has found somewhat of an echo in the Arab and Muslim world, but some Muslim religious circles such as Al-Azhar (Egypt), the most important Islamic centre in the world, try to justify it on the basis of sunnah (that is, to conform with the tradition of the prophet Mohammed). Male circumcision is practised by all Muslims and Jews and also by some Christians in Egypt, in the United States and Canada). For different reasons, the debate on this topic is still taboo in Western and in Arab and Muslim countries. The object of this study is to define the role of Islamic law and Muslim religious leaders in female and male circumcision. On purpose, it avoids any use of the word 'Islam', and concentrates on the written sources of Islamic law and the opinions of contemporary Arab authors, mostly of Egyptian origin. Juridical logic cannot acknowledge the distinction between female and male circumcision, both being the mutilation of healthy organs which is damaging to the physical integrity of the child, whatever the underlying religious motivations. Furthermore, both practices violate the Koran: 'Our Lord, You did not create all this in vain' (3:191), and '[He] perfected everything He created' (32:7). In our opinion, a god who demands that his believers be mutilated and branded on their genitals the same as cattle, is a god of questionable ethics. To mutilate children, boys or girls, under the pretext that it is for their own good, shows the influence of cynicism and fanaticism.

    Orbital cellulitis in children is a rare but potentially serious condition. The goal of this study is to analyze the epidemiological, clinical, therapeutic aspects and typical course of orbital and periorbital cellulitis in children, so as to propose a clinical management protocol adapted to our context. During the retrospective study period (2008-2014), 28 cases were hospitalized in the pediatric department at the Mohammed VI university medical center in Marrakech. Eighty-five percent of the cases were diagnosed as preseptal cellulitis, and 15% as retroseptal cellulitis. The age of the patients ranged from 6 months to 14 years with a mean age of 3 years. We report a female predominance with a prevalence of 58%. In our study, the most common cause is extension of infection from sinusitis. Clinically, fever was present in 19 patients (68%), eyelid edema was universal, proptosis and chemosis were noted in 2 cases, and ptosis in one patient. Bacteriological testing identified micro-organisms in 6 cases. Orbital computed tomography performed in 57% of the cases showed preseptal cellulitis in 12 cases, orbital cellulitis in one case, a subperiosteal abscess in 2 cases, and orbital abscess in one case. Medical treatment was based on amoxicillin-clavulanic acid or the combination of ceftriaxone, metronidazole±aminoglycoside. However, surgical drainage was necessary in 1 case. The outcome of all cases was favorable. Orbital cellulitis in children is usually preseptal, and amoxicillin-clavulanic acid is considered to be the standard empiric treatment.

L’âge moyen était de 53 ans. Il existait une prédominance masculine (9 hommes - 3 femmes). Tous les patients présentaient un syndrome occlusif avec arrêt des matières et des gaz. L’abdomen sans préparation montrait des niveaux hydro-aériques chez tous les patients. La tomodensitométrie objectivait un processus colique sténosant avec dilatation des anses en amont. Tous les patients ont bénéficié de la mise en place d’une endoprothèse par colonoscopie sous anesthésie générale. Le succès technique immédiat et clinique était noté dans 95% des cas. La migration de la prothèse a été notée dans un cas. Les endoprothèses coliques constituent une alternative de choix au traitement chirurgical des sténoses tumorales coliques symptomatiques, soit pour permettre de préparer au traitement curatif chirurgical “à froid”, soit dans un but palliatif avant de débuter une éventuelle chimiothérapie.

Although bearing a relatively slow deformation with regards to the East Africa Rift System, the Nubia plate previously considered as a homogeneous tectonic block appears to be dislocating progressively also forming a system of microplates. A synthesis of earthquake studies and regional deformation exposed in a seismotectonic map hitherto serves as a basis for the seismic hazard evaluations and the reduction of seismic risks. * IGCP/SIDA: International Geoscience Program/Swedish International Cooperation Authority http://www.unesco.org/science/IGCP IGCP-601 Working Group: Paulina Amponsah (Ghana Atomic Energy Commission), Atalay Ayele (Addis Ababa University, Ethiopia), Bekoa Ateba (Inst. of Geol. and Min.

    We review our recent contributions [1,2,3,4] in the light of their omission in recent publications [5,6,7,8]. Included is the VAVD process ( also called: secondary baroclinic circulation generation) which yields more positive and negative circulation through intermediate times than the original shock-accelerated vortex deposition (SAVD). VAVD is due to the acceleration provided by the rolled up vortex from SAVD and more important, the strongly increased density gradients of the multiphase front, also caused by the roll-up process . In addition we quantify : the effect of the initial thickness of the interfacial transition layer; the approach to constant a-dot at intermediate-to-late times; the ubiquity of vortex projectiles and transition to turbulence.

    Nigeria is the most populous country in Africa and in 2012 was suffering some of the lowest vaccination rates in the World. A combination of factors had resulted in a dysfunctional immunization cold chain and supply chain. Recognizing that the number of unimmunized children contributed to high levels of under-5-mortality, and that health MDGs would not be attained, Minister of State for Health Mohammed Pate launched a vaccines transformation project in 2013. In partnership with BMGF, GAVI, UNICEF, WHO, other donors and implementing partners the transformation journey has so far taken three years and achieved impressive results. It has though faced challenges along the way and with the financial burden of GAVI graduation facing Nigeria, the economic downturn and the decentralized funding of health services, the results are far from sustained. This paper documents the work undertaken at the Federal level and then highlights specific work undertaken in partnership with Lagos State Government. It identifies the importance of taking an end to end approach and looking at the root causes of weak system performance. The strategy combined simple innovations in how data was captured, recorded and used to drive decision making. It included a comprehensive and systematic approach to cold chain procurement, installation and maintenance with a shift to a culture of active cold chain maintenance that is performing with higher levels of uptime. It also included supply chain redesign at both the Federal and State level. Finally, it involved an institutional transformation at the National Primary Health Care Development Agency (NPHCDA) to establish a data driven Department of Logistics and Health Commodities (DLHC) to manage the many challenges in immunizing 7.5 million children annually. While results have been impressive, there have been many challenges and lessons learned on the way. As Nigeria gets ready for its graduation from GAVI, a robust agile performing cold chain and

    United Arab Emirates (UAE) has entered the space exploration race with the announcement of Emirates Mars Mission (EMM), the first Arab Islamic mission to another planet, in 2014. Through this mission, UAE is to send an unmanned probe, called Hope probe, to be launched in summer 2020 and reach Mars by 2021 to coincide with UAE's 50th anniversary. Through a sequence of subsequent maneuvers, the spacecraft will enter a large science orbit that has a periapsis altitude of 20,000 km, an apoapsis altitude of 43,000 km, and an inclination of 25 degrees. The mission is designed to (1) characterize the state of the Martian lower atmosphere on global scales and its geographic, diurnal and seasonal variability, (2) correlate rates of thermal and photochemical atmospheric escape with conditions in the collisional Martian atmosphere, and (3) characterize the spatial structure and variability of key constituents in the Martian exosphere. These objectives will be met by four investigations with diurnal variability on sub-seasonal timescales which are (1) determining the three-dimensional thermal state of the lower atmosphere, (2) determining the geographic and diurnal distribution of key constituents in the lower atmosphere, (3) determining the abundance and spatial variability of key neutral species in the thermosphere, and (4) determining the three-dimensional structure and variability of key species in the exosphere. EMM will collect these information about the Mars atmospheric circulation and connections through a combination of three distinct instruments that image Mars in the visible, thermal infrared and ultraviolet wavelengths and they are the Emirates eXploration Imager (EXI), the Emirates Mars InfraRed Spectrometer (EMIRS), and the EMM Mars Ultraviolet Spectrometer (EMUS). EMM has passed its Mission Concept Review (MCR), System Requirements Review (SRR), System Design Review (SDR), and Preliminary Design Review (PDR) phases. The mission is led by Emiratis from Mohammed

    Between 1995 and 1997, in the territories of Southern Italy, there were fifteen murders of elderly women over the age of 70 years old. Initially, however, not all the murders were attributed to a single serial killer. The majority of the victims were stabbed multiple times in the neck, except for three cases in which the cause of death was manual strangulation. There was evidence of sexual assault in only one of the cases. All the victims were discovered in their own apartments, which were located on the ground level, with no signs of forced entry. In most of the cases, the offender stole money and/or jewellery. A multi-disciplinary team reviewed the cases during the investigation and created a profile of the killer. The team determined that the method of operation was completely unusual for the local criminal element. They suggested that the perpetrator could be an immigrant, who committed the murders for sexual motivation and who may have been arrested previously for sex-related incidents. On 15th September 1997, a suspect was arrested. He was identified as Ben Mohamed Ezzedine Sebai, a 35-year-old white male, originally from Tunisia. He was charged and convicted of four of the murders and was given a life sentence. In 2005, Sebai confessed to the murders of four additional elderly women, for which nine other people had already been previously tried and convicted, among them, a man who committed suicide in jail. In 2007, Sebai finally confessed to committing fifteen murders that occurred between 1995 and 1997. Sebai also admitted to experiencing sexual gratification at every homicide scene, even though there was no physical proof at most of the crime scenes. The goal of this article is to illustrate a little-known but noteworthy case concerning a serial sexual killer of elderly women that occurred in Southern Italy, highlighting the method of operation, the victim selection process, and the injuries inflicted. The article will also discuss his motivation, the

    Summary L'infection nosocomiale bactérienne étant l'une des principales causes de morbidité et de mortalité chez le brûlé, nous avons réalisé une étude rétrospective portant sur 84 patients hospitalisés au sein du service de réanimation des brûlés de l'Hôpital Militaire d'Instruction Mohammed V de Rabat, sur une période de 3 ans, du premier janvier 2001 au 31 décembre 2003. Les critères d'infection nosocomiale étaient ceux du Center for Disease Control d'Atlanta de 1988. Les taux d'incidence ont été calculés. La population infectée a été comparée à celle non infectée. L'écologie bactérienne du service a été décrite comme aussi l'antibiotype. Il ressort de cette étude la survenue de 87 infections nosocomiales chez 27 patients. L'incidence cumulative était de 103 infections pour 1000 jours de traitement. Pour ce qui est des caractéristiques des infections bactériennes, les sites infectés étaient la peau (77%), le sang (13,8%), les voies urinaires (8%) et les poumons (1,1%). Les principaux germes étaient: Staphylococcus sp. (33,3%), Pseudomonas aeruginosa (23%), Enterococcus faecalis et Acinetobacter (8%). Les staphylocoques étaient méticillo-résistants dans 22,2% des cas. Le Pseudomonas et l'Acinetobacter étaient multirésistants (60%). Dans notre étude les facteurs prédictifs de survenue des infections nosocomiales que nous avons retenus après l'étude comparative des populations infectées et non infectées ont été l'âge, le body mass index, l'abbreviated burn severity index et le remplissage initial. En isolant ces paramètres, nous avons pu établir une équation à valeur prédictive de survenue d'infection nosocomiale chez le patient brûlé. PMID:21991158

Patients on renal replacement were excluded. CMS infusion was given over 30 min or 1 h. Repeated blood sampling was performed after the loading dose and after the 5th or 6th dose. Colistin concentrations and measured CMS, determined after hydrolization to colistin and including the partially sulfomethylated derivatives, were determined with a liquid chromatography-tandem mass spectrometry assay.

    L'encéphalopathie pancréatique, est une complication rare de la pancréatite aiguë, notre étude porte sur 02 cas d'encéphalopathie pancréatique, hospitalisés et traités au sein du service de Réanimation chirurgicale de l'Hôpital Militaire d'Instruction Mohamed V de Rabat. L'âge des patients était compris entre 43 ans et 54 ans, nos 02 cas sont repartis en une femme et un homme. Le mécanisme physiopathologique de l'EP n'est pas encore bien élucidé, de nombreuses hypothèses ont été rapportées dans la littérature, certains auteurs suggèrent que la lipase et la Phospholipase A2 jouent un rôle dans le processus pathologique de l'EP. D'autres facteurs tels que les infections, les troubles hydroélectrolytiques, l'hypoxémie et la perturbation de la glycémie, peuvent être déclencheurs. Le diagnostic de l'encéphalopathie pancréatique est facile à établir, la symptomatologie clinique se résume le plus souvent à une confusion, avec stupeur, et agitation psychomotrice, Il s'y ajoute parfois des atteintes neurologiques comme des convulsions, une céphalée, des hémiparésies passagères, une dysarthrie, enfin des difficultés d'expression verbale et une amnésie. Les examens paracliniques, notamment L'IRM cérébrale et l'électroencéphalogramme, permettent de confirmer le diagnostic. Le traitement est d'abord symptomatique, il a comme objectif de lutter contre les facteurs qui favorisent l'apparition des signes neurologiques par les mesures de réanimation que réclame la gravité de la situation. L'évolution de l'EP est le plus souvent favorable, avec une disparition progressive des symptômes, cependant la persistance de quelques séquelles, est décrite dans la littérature. Le pronostic est fonction de la gravité de la pancréatite aigüe et des complications associées. Dans notre étude les données sont globalement comparables à celles publiées actuellement par la majorité des auteurs. PMID:28292109

    BACKGROUND The rise in childhood eye diseases has become a matter of concern in Saudi Arabia, and hence a study has been conducted on the residents of Jazan. The aim of the research was to find out the root cause of such issues and provide a solution to prevent such circumstances for it may affect the vision of children. In this study, therefore, we aimed to determine the types of childhood eye diseases in Jazan and to discuss the best ways to prevent them or prevent their effect on the vision of our children. Our institutions are working toward the longevity and welfare of the residents, and healthcare is one of the important aspects in such a field. METHODS This is a retrospective review of all patients less than 18 years of age who presented to the pediatric ophthalmology clinic of Prince Mohammed Bin Nasser Hospital, Jazan, between October 2014 and October 2015. The data, collected on 385 cases, included the age at first presentation, sex, clinical diagnosis, refractive error (RE) if present, and whether the child had amblyopia. If the child did not undergo complete ophthalmic examination with cycloplegic refraction, he/she was excluded. All data were collected and analyzed using the software SPSS. A P-value < 0.05 was considered statistically significant. RESULTS We reviewed the files of 385 children, with a male/female ratio of 1.1:1.0. The group aged 0–6 years made up the largest group (P = 0.01), and the ratio is an expression to define the credibility of the study using a chi-squared test. Strabismus (36.9%), RE (26.5%), ocular trauma (7.5%), infection of cornea and conjunctiva (7.3%), and keratoconus (6.2%) were the most common conditions. There was no significant difference in presentation by age group and sex among children with REs and squint. Trauma was seen more commonly among males and in the group aged 12–18 years. CONCLUSION In this retrospective study, the focus was on the common childhood eye diseases that were considerably high

    An estimated 1.2 billion people in the world do not have access to constant supply of electricity. The goal of this research project is experimental investigation of cooling mechanisms for low cost refrigeration without constant supply of electricity. Experimental investigations were performed in 3 separate phases: 1) We first tested common literature method of evaporative cooling mechanism of the pot-in-pot refrigeration system, developed by Mohammed Bah Abba. Experiments showed that the cooling power of the original system is theoretically limited to the wet bulb temperature, and in an environment with 70º F ambient temperature, cooling never exceeded 7-8 degrees. 2) Next, we conducted an experimental study of heat transfer processes through the use of a simple glass model. The results of the glass model showed that thorough insulation and ice were crucial to improving cooling. Hence, we incorporated the use of ice and insulating fabrics in the system. This improved the existing methods by 2x but required much maintenance, with constant watering of sand and replacement of ice packs. Our next set of experiments with a 60-liter clay pot filled with water and 3.5-8 kg ice blocks showed that more than 20 degree cooling can be achieved with moderate amount of ice and insulation for over a few days. 3) Next, we used HOBO temperature sensors, a 60-liter pot, water, ice, and several layers of insulation, and proved that with proper insulation and even just one 8-kg block of ice, the system yielded a greater cooling for over two weeks, with temperatures ranging from 61.8 and 68.9 ºF even when the ambient temperature was as high as 109º F. The temperature inside the system stayed relatively constant, with changes only corresponding to day and night. Additional experimentation showed that initial cooling was proportional to the amount of ice put in the system, and thus with double the ice, temperatures could reach as low as 34.9 ºF. This research proves that the

    ABSTRACT Background: Before arrival into doctor’s clinic, child might have acquired an impression of a clinical environment and doctor’s appearance. Different kind of doctor’s attire may evoke different reactions. By understanding children and parent’s perception and preferences about dentist’s attire, a suitable dress code could be adopted to establish good rapport with children. Aim: To evaluate children and parental perceptions and preferences towards dentist attire. Materials and methods: A questionnaire designed with series of photographs of male and female dental students in different attires was responded by 150 parents aged 29 to 63 years and 150 children aged 9 to 13 years. Results: Seventy percent of children participants (n = 104) and 42% of parents participants (n = 63) favored the traditional white coat attire. However, 58% parents (n = 87) significantly preferred non-white coat attires in comparison to 30% of children (n = 46) (χ2 = 21.61, p < 0.001). No statistical significant difference was noted among the children and the parents, both favoring the use of protective wear (χ2 = 0.99 p > 0.05), no-significant association was found between parents and children response to white coat (χ2 = 0.39, p = 0.53). A highly significant difference was found between the male participants, who favored the male dentist and female participants preferring the female dentist (χ2 = 47.16, p < 0.001). Conclusion: Our study attempted to rule out the stereotyped concept of ‘white coat fear’ among children, both children and parents favored traditional white coat attire, contrary to popular misconception ‘white coat syndrome’. However, use of child friendly attires could be useful in anxious children for better practice management.

    Le pyo-pneumothorax tuberculeux est une complication rare mais grave de la tuberculose pulmonaire évolutive. Nous rapportons une série de 18 cas de pyo-pneumothorax tuberculeux colligés au service de Pneumo-Phtisiologie de l'Hôpital Militaire d'Instruction Mohammed V de Rabat entre janvier 2005 et décembre 2009. Il s'agit de 15 hommes et 3 femmes d’âge moyen de 35 ans ±7 ans. 4 patients étaient diabétiques. Le tabagisme était retrouvé chez 9 cas. Le pyo-pneumothorax était du coté droit dans 13 cas. La radiographie thoracique avait montré des lésions cavitaires chez 15 patients et des lésions étendues et bilatérales chez 8 cas. La recherche de BK dans le liquide de tubage gastrique était positive chez 16 cas. Un drainage thoracique associé à un traitement antituberculeux selon le régime 2SRHZ/7RH et une kinésithérapie respiratoire ont été instaurés chez tous les cas. La durée moyenne de drainage pleural était de 4 semaines. Chez 3 cas on avait noté la persistance de la suppuration pleurale ayant nécessité une toilette pleurale sous thoracoscopie avec pleurectomie et exérèse pulmonaire limitée emportant la lésion parenchymateuse tuberculeuse et la persistance d'une volumineuse poche pleurale avec trouble ventilatoire restrictif ayant nécessité une décortication pleurale chirurgicale chez deux cas. L’évolution était favorable avec pachypleurite séquellaire minime chez le reste des cas. Le pyo-pneumothorax tuberculeux est une forme grave, qui est souvent en rapport avec une tuberculose cavitaire active. L’évolution est généralement trainante malgré le traitement antituberculeux et le drainage thoracique, d'où la nécessité d'un diagnostic et un traitement précoce de toute forme de tuberculose.

    Bicuspid aortic valves calcify at a significantly higher rate than normal aortic valves, a process that involves increased inflammation. Because we have previously found that bicuspid aortic valve experience greater stretch, we investigated the potential connection between stretch and inflammation in human aortic valve interstitial cells (AVICs). Microarray, quantitative PCR (qPCR), and protein assays performed on AVICs exposed to cyclic stretch showed that stretch was sufficient to increase expression of interleukin and metalloproteinase family members by more than 1.5-fold. Conditioned medium from stretched AVICs was sufficient to activate leukocytes. microRNA sequencing and qPCR experiments demonstrated that miR-148a-3p was repressed in both stretched AVICs (43% repression) and, as a clinical correlate, human bicuspid aortic valves (63% reduction). miR-148a-3p was found to be a novel repressor of IKBKB based on data from qPCR, luciferase, and Western blot experiments. Furthermore, increasing miR-148a-3p levels in AVICs was sufficient to decrease NF-κB (nuclear factor kappa-light-chain-enhancer of activated B cells) signaling and NF-κB target gene expression. Our data demonstrate that stretch-mediated activation of inflammatory pathways is at least partly the result of stretch-repression of miR-148a-3p and a consequent failure to repress IKBKB. To our knowledge, we are the first to report that cyclic stretch of human AVICs activates inflammatory genes in a tissue-autonomous manner via a microRNA that regulates a central inflammatory pathway.—Patel, V., Carrion, K., Hollands, A., Hinton, A., Gallegos, T., Dyo, J., Sasik, R., Leire, E., Hardiman, G., Mohamed, S.

    Le cancer du sein est le plus fréquent chez la femme et figure parmi les principales causes de mortalité liées au cancer. La curabilité de ce type tumoral est en augmentation, grâce aux programmes de dépistage et aux progrès thérapeutiques, qui ont certes augmenté la survie des patients. Mais des défis restent à relever en rapport avec l’instabilité phénotypique des cellules cancéreuses. L’objectif de ce travail est d’étudier le profil phénotypique du cancer du sein chez les patients pris en charge au Centre Mohammed VI pour le traitement des Cancers, durant les années 2013-2014. Il s’agit d’une étude transversale sur deux années, incluant les cas du cancer du sein pris en charge au Centre. Le recueil des données était fait à partir des dossiers des patients et analysés par le logiciel Epi Info. 1277 patients ont été pris en charge au sein de notre centre. 99,5% des cas de sexe féminin, l’âge moyen était 50,20 ± 11,34 ans. Le type histologique le plus fréquent était le carcinome canalaire infiltrant (80,7% des cas). Le stade diagnostic était précoce (56,9%). Le phénotype moléculaire le plus fréquent était le luminal A (41,4% des cas). Le luminal B, le HER2 et les triples négatifs étaient dans respectivement 10,4%, 6,3%, 11,2% des cas. L’étude du phénotype tumoral des patients atteints du cancer du sein permet l’orientation du clinicien dans le choix du traitement, et des décideurs dans la planification de programmes de lutte contre cette pathologie.

Influenza and Other Respiratory Viruses 6(3), e25–e29. Background  Quantitative knowledge of the transmissibility of influenza is crucial to its prevention and control. Objectives  To quantify the transmission of influenza A (H1N1) and seasonal influenza in household contacts of patients with influenza diagnosed in a large university hospital. Patients/Methods  A prospective study was conducted between September and October 2009 in which all confirmed cases of influenza diagnosed at King Khalid University Hospital were included. All household contacts were followed by telephone calls every other day for 12 days. They were asked about the development of influenza symptoms in addition to their age and nationality. Results  Overall, 432 household contacts of 69 influenza A (H1N1) cases and 417 contacts of 91 seasonal influenza cases were included. Suspected influenza was diagnosed in 16·9% and 14·4% of household contacts of H1N1 and seasonal influenza patients, respectively. Household reproduction numbers were 1·06 (0·84–1·28) for H1N1 and 0·66 (0·51–0·81) for seasonal influenza. Children in households were more susceptible than were adults (22·2% versus 13·7%, respectively). Evidence of coughing in the index case tripled the risk of infection in households afflicted with the H1N1 influenza [relative risk (RR) = 3·28, CI = 1·24–8·69], while evidence of a runny nose doubled it (RR = 1·89, CI = 1·19–2·92). Conclusions  Communicability of influenza in households in Riyadh is comparable to that in other countries. Children are more susceptible to influenza infection. The presence of a cough or runny nose in the index cases increases the risk of infection. PMID:22118477

    L'infection nosocomiale bactérienne étant l'une des principales causes de morbidité et de mortalité chez le brûlé, nous avons réalisé une étude rétrospective portant sur 84 patients hospitalisés au sein du service de réanimation des brûlés de l'Hôpital Militaire d'Instruction Mohammed V de Rabat, sur une période de 3 ans, du premier janvier 2001 au 31 décembre 2003. Les critères d'infection nosocomiale étaient ceux du Center for Disease Control d'Atlanta de 1988. Les taux d'incidence ont été calculés. La population infectée a été comparée à celle non infectée. L'écologie bactérienne du service a été décrite comme aussi l'antibiotype. Il ressort de cette étude la survenue de 87 infections nosocomiales chez 27 patients. L'incidence cumulative était de 103 infections pour 1000 jours de traitement. Pour ce qui est des caractéristiques des infections bactériennes, les sites infectés étaient la peau (77%), le sang (13,8%), les voies urinaires (8%) et les poumons (1,1%). Les principaux germes étaient: Staphylococcus sp. (33,3%), Pseudomonas aeruginosa (23%), Enterococcus faecalis et Acinetobacter (8%). Les staphylocoques étaient méticillo-résistants dans 22,2% des cas. Le Pseudomonas et l'Acinetobacter étaient multirésistants (60%). Dans notre étude les facteurs prédictifs de survenue des infections nosocomiales que nous avons retenus après l'étude comparative des populations infectées et non infectées ont été l'âge, le body mass index, l'abbreviated burn severity index et le remplissage initial. En isolant ces paramètres, nous avons pu établir une équation à valeur prédictive de survenue d'infection nosocomiale chez le patient brûlé.

    Background In patients with heart failure, left bundle branch block (LBBB) seems to be associated with an increased risk of cardiovascular mortality. Purpose The purpose of this study is to determine the in-hospital outcome of congestive heart failure patients with LBBB versus those without. Methods We conducted a prospective observational study at the Department of Intensive Care and Rhythmology at the Mohammed V Military Hospital of Rabat, where 330 patients were admitted for heart failure between January 2008 and September 2012. Screening out patients with missing data yielded a cohort of 274 patients. Among the 274 patients, only 110 had LBBB and a left ventricular ejection fraction lower than 50%. We randomly selected a subset of 110 patients diagnosed as non-LBBB to ensure a significant statistical comparison between LBBB and non-LBBB patients. We therefore considered two groups in our analysis: 110 heart failure (HF) patients with LBBB and 110 HF patients without LBBB. Patients with incomplete records were excluded. Results Male gender was dominant in both groups (82.7% vs. 66.7%, p = 0.005). Patients with LBBB had a higher prevalence of idiopathic dilated cardiomyopathy (39.1% vs. 4.8%, p < 0.001); and a higher prevalence of previous hospitalization for heart failure (64.5% vs. 23.3%, p < 0.001). The left ventricular ejection fraction was significantly lower in the group with LBBB (25.49% vs. 39.53%, p < 0.001). Age, cardiovascular risk factors, rhythmic and thromboembolic complications did not significantly differ. In patients with LBBB, 61.8% received cardiac resynchronization therapy performed both during the index hospital stay (50.9%) and previously (10.9%). Hospital outcome was marked by 20 in-hospital deaths in the group with LBBB and eight deaths in the group without LBBB (p = 0.008). Conclusion Our analysis emphasizes increased in-hospital mortality and higher disease severity, over a short period of stay, in heart failure patients with

    Les tumeurs annexielles cutanées sont des tumeurs primitives cutanées à la fois rares et hétérogènes. Elles sont le plus souvent bénignes et rarement malignes. Elles sont dominées du point de vu morphologique par leur polymorphisme lésionnel. Le but de cette étude est de relever le profil épidémiologique et les différents aspects anatomopathologiques de ce groupe de tumeurs dans une cohorte de population marocaine et de les comparer avec les données de la littérature. Il s'agit d'une étude rétrospective de 96 cas de tumeurs annexielles cutanées colligées au service d'anatomie et de cytologie pathologique de l'Hôpital Militaire d'Instruction Mohammed V de rabat durant une période de 6 ans, de Janvier 2009 à Décembre 2014. Le pic de fréquence est situé entre 31 et 40 ans. L’âge moyen est de 36 ans avec une prédominance masculine (63,5%). Le siège de prédilection est la région de la tête et cou (47,9%). Les tumeurs bénignes (97,9%) sont plus fréquentes que les tumeurs malignes. La différenciation est folliculaire dans 51% des cas, eccrine/apocrine dans 44,8% des cas et sébacée dans 4,2% des cas. Le type histologique le plus fréquent est le pilomatrixome (33,4%) suivi par l'hidradénome (12,5%) et le spiradénome eccrine (11,5%). Les tumeurs annexielles cutanées sont rares et très variées. Le profil épidémiologique et les aspects anatomopathologiques qui ressortent sont globalement superposables à ceux rapportés dans la littérature. Elles sont majoritairement bénignes, à prédominance masculine et dominées par le pilomatrixome et l'hidradénome nodulaire. Les tumeurs malignes sont rares, agressives et surviennent à un âge plus avancé. PMID:26185579

    To elucidate the biosynthetic pathways of carotenoids, especially myxol 2′-glycosides, in cyanobacteria, Anabaena sp. strain PCC 7120 (also known as Nostoc sp. strain PCC 7120) and Synechocystis sp. strain PCC 6803 deletion mutants lacking selected proposed carotenoid biosynthesis enzymes and GDP-fucose synthase (WcaG), which is required for myxol 2′-fucoside production, were analyzed. The carotenoids in these mutants were identified using high-performance liquid chromatography, field desorption mass spectrometry, and 1H nuclear magnetic resonance. The wcaG (all4826) deletion mutant of Anabaena sp. strain PCC 7120 produced myxol 2′-rhamnoside and 4-ketomyxol 2′-rhamnoside as polar carotenoids instead of the myxol 2′-fucoside and 4-ketomyxol 2′-fucoside produced by the wild type. Deletion of the corresponding gene in Synechocystis sp. strain PCC 6803 (sll1213; 79% amino acid sequence identity with the Anabaena sp. strain PCC 7120 gene product) produced free myxol instead of the myxol 2′-dimethyl-fucoside produced by the wild type. Free myxol might correspond to the unknown component observed previously in the same mutant (H. E. Mohamed, A. M. L. van de Meene, R. W. Roberson, and W. F. J. Vermaas, J. Bacteriol. 187:6883-6892, 2005). These results indicate that in Anabaena sp. strain PCC 7120, but not in Synechocystis sp. strain PCC 6803, rhamnose can be substituted for fucose in myxol glycoside. The β-carotene hydroxylase orthologue (CrtR, Alr4009) of Anabaena sp. strain PCC 7120 catalyzed the transformation of deoxymyxol and deoxymyxol 2′-fucoside to myxol and myxol 2′-fucoside, respectively, but not the β-carotene-to-zeaxanthin reaction, whereas CrtR from Synechocystis sp. strain PCC 6803 catalyzed both reactions. Thus, the substrate specificities or substrate availabilities of both fucosyltransferase and CrtR were different in these species. The biosynthetic pathways of carotenoids in Anabaena sp. strain PCC 7120 are discussed. PMID:18708496

    Zinc sulphide (ZnS) and Mn-doped ZnS nanoparticles were synthesized by wet chemical method. The synthesized nanoparticles were characterized by UV-visible, fluorescence, X-ray diffraction (XRD), fourier transform infra-red (FTIR) spectrometer, field emission scanning electron microscope (FESEM) and high resolution transmission electron microscope (HRTEM). Scanning electron microscope (SEM) was used to find particle size while chemical composition of the synthesized materials was investigated by EDAX. UV-visible absorption spectrum of Mn-doped ZnS was slightly shifted to lower wavelength with respect to the un-doped zinc sulphide with decrease in the size of nanoparticles. Consequently, the band gap was tuned from 3.04 to 3.13 eV. The photoluminescence (PL) emission positioned at 597 nm was ascribed to 4T1 → 6A1 transition within the 3d shell of Mn2+. X-ray diffraction (XRD) analysis revealed that the synthesized nanomaterials existed in cubic crystalline state. The effect of embedding un-doped and doped ZnS nanoparticles in the active layer and changing the ratio of PCBM ([6, 6]-phenyl-C61-butyric acid methyl ester) to nanoparticles on the performance of hybrid solar cell was studied. The device with active layer consisting of poly(3-hexylthiophene) (P3HT), [6, 6]-phenyl-C61-butyric acid methyl ester (PCBM), and un-doped ZnS nanoparticles combined in the ratio of (1:0.5:0.5) attained an efficiency of 2.42% which was found 71% higher than the reference device under the same conditions but not containing nanoparticles. Replacing ZnS nanoparticles with Mn-doped ZnS had a little effect on the enhancement of efficiency. The packing behavior and morphology of blend of nanoparticles with P3HT:PCBM were examined using atomic force microscope (AFM) and XRD.

    Les hypertensions artérielles (HTA) d'origine endocrine restent une cause rare d'HTA, sa prévalence globale n'excède pas 4% des hypertendus. L'intérêt de la recherche des HTA endocrines réside dans la gravité de certaines formes parfois mortelles et le caractère potentiellement curable et réversible de ces HTA. Le but du travail est de déterminer le profil clinique, para clinique, étiologique et thérapeutique des HTA secondaires d'origine endocrine chez les patients suivis au service d'endocrinologie au CHU Mohamed IV à Marrakech. Il s'agit d'une étude descriptive prospective s’étalant sur une période de 4 ans incluant 45 patients ayant une HTA endocrinienne. La moyenne d’âge est de 44,89 ans, avec une nette prédominance du sexe féminine (sexe ratio de 0,49). Les étiologies des HTA endocrines étaient dominées par le phéochromocytome (17 cas), l'hypercorticisme (11 cas) et l'acromégalie (8 cas). L'HTA était paroxystique dans 24,4%. Elle était d'emblée sevère classée grade 3 dans 40% des cas. L'HTA a été compliquée de cardiopathie dans 24% des cas et de néphropathie dans 20% des cas. Le traitement curatif a permis une guérison de l'HTA chez 60% (27 cas). Le diagnostic des HTA secondaires endocrines est parfois difficile du fait de l'absence de spécificité clinique. Il n'est pas exceptionnel que l'HTA soit l'unique manifestation de la maladie. Dans notre travail nous notons le caractère paroxystique et sévère de l'HTA. Le caractère éventuellement curable des HTA endocrines, dans plus des deux tiers des cas, fait qu'il est important de la dépister devant toute HTA sévère, résistante au traitement, ou en présence de signes cliniques, biologiques ou radiologiques évocateurs.

    Le médulloblastome est une tumeur neuro-ectodermique primitive maligne. Il s'agit d'une tumeur rare chez l'adulte, représentant moins de 1% des tumeurs cérébrales. Nous proposons une étude rétrospective réalisée au sein du service d'Oncologie-Radiothérapie du CHU Mohamed VI de Marrakech sur une période de 13 ans. Le but de notre travail est de déterminer le profil épidémioclinique, thérapeutique, évolutif ainsi que les facteurs pronostiques de cette entité pathologique avec une revue de la littérature. Notre série comportait 13 patients, 10 hommes et 3 femmes, l’âge médian a été 20,8 ans. Le tableau clinique a été révélé par un syndrome d'hypertension intracrânienne (100%), associée à un syndrome cérébelleux (84%). La localisation était hémisphérique (31%) et vermio-hémisphérique (54%). 31% des patients ont bénéficié d'une exérèse chirurgicale totale. 85% des cas avaient une variante classique et 15% une variante desmoplasique. 30% des cas avaient été classés à «risque standard» et 70% à «haut risque». La chirurgie avait été complétée d'une radiothérapie de l'ensemble du névraxe selon la technique de «jonctions mobiles» dans tous les cas. Le délai moyen était de 73 jours. Une chimiothérapie adjuvante avait été réalisée chez 9 cas. Avec un recul moyen de 21.3 mois, l’évolution a été marquée par une récidive tumorale (4 cas), une toxicité auditive (6 cas) et des troubles cognitifs chez un cas. La prise en charge du médulloblastome doit être multidisciplinaire associant neurochirurgiens et oncologues radiothérapeutes. Cette collaboration est le seul garant d'une amélioration de son pronostic. PMID:26889307

    L'hépatite C demeure la principale infection virale chez l'hémodialysé, dont la prise en charge thérapeutique ainsi que la gestion de ses effets secondaires restent difficiles. Il s'agit d'une étude rétrospective portant sur tous les patients atteints d'hépatite C chronique ayant une insuffisance rénale chronique sous hémodialyse, suivis au service de gastroentérologie au CHU Mohamed VI de Marrakech sur une période de Janvier 2004 à Décembre 2014. Sur un total de 355 cas d'hépatite virale C, 13 patients étaient hémodialysés (3,66%). Dix patients ont été traités, soit 76,94% des cas. Le traitement n’était pas indiqué chez 2 patients ayant une fibrose minime sans cytolyse. Il était contre-indiqué chez une patiente multitarée. Deux malades ont eu une réponse virologique rapide et 5 une réponse virologique précoce. Le taux de réponse virologique soutenue était de 40%, 30% des patients étaient non répondeurs. Le traitement fut arrêté chez 2 patientes pour effets secondaires sévères. Un seul patient a été candidat à une transplantation rénale. En analyse multivariée, la réponse virologique soutenue a été significativement associée à certains facteurs prédictifs de bonne réponse thérapeutique: Age jeune ≤40 ans (P=0,0057), fibrose minime F1-F2 (P=0,03), génotype non 1 (P=0,0064), charge virale préthérapeutique <800000 UI/ml (P=0,013), et l'absence d'arrêt thérapeutique (P=0,028). La gestion efficace des effets secondaires du traitement de HVC permet d'obtenir chez l'hémodialysé un taux de réponse virologique soutenue avoisinant celui de la population générale. PMID:27022433

    L'inhalation accidentelle du corps étranger est rare chez les adultes et les adolescents. L’épingle à foulard est un corps étranger particulier de plus en plus fréquent chez les femmes qui portent le voile. Le but de notre travail est de décrire les particularités liées à l'inhalation de cet objet éguisé à conséquences lourdes, et la nécessité d'un programme de sensibilisation et d’éducation. Dix jeunes patientes, toutes voilées, ont été hospitalisées au service de chirurgie thoracique du CHU Mohammed VI d'Oujda entre janvier 2010 et juillet 2014 pour inhalation d’épingle à foulard. La moyenne d’âge a été de 15 ans. L'inhalation a été accidentelle dans tous les cas, alors que les patientes s'initiaient au port du voile. Le syndrome de pénétration a été retrouvé dans tous les cas. L'examen clinique a été normal chez toutes les patientes. La radiographie thoracique a montré le corps étranger sous forme d'une opacité linéaire, localisée au niveau de la trachée dans 3 cas, à droite dans 4 cas, gauche dans 3 cas. La bronchoscopie rigide a réussi à extraire l’épingle dans 8 cas. L’épingle a été rejetée spontanément dans un cas et une patiente a dû être opérée. L’épingle à foulard est un corps étranger particulier de plus en plus fréquent chez les femmes qui portent le voile islamique, il faut souligner la nécessité d'un programme d’éducation de la santé envers cette population. La bronchoscopie rigide reste le principal outil de récupération de ces corps étrangers inhalés. PMID:26587173

    L'ostéoporose endocrinienne devrait devenir rare aujourd'hui puisque les endocrinopathies ont bénéficié d'un diagnostic plus précoce. Cependant elle reste fréquente, sous diagnostiquée et peu prise en charge. Sa gravité est essentiellement liée au risque fracturaire, et au risque élevé de morbi-mortalité. Le but de notre travail est de déterminer le profil ostéodensitométrique des patients suivis pour endocrinopathie et de définir les caractéristiques de l'ostéoporose et de l'ostéopénie chez ces patients. Il s'agit d'une étude de type transversale, descriptive portant sur 63 patients suivis pour endocrinopathies au service d'Endocrinologie-Diabétologie du CHU Mohamed VI de Marrakech, s’étalant sur une période de 02 ans allant du début du mois de Janvier 2012 au mois de Janvier 2014. La moyenne d’âge des patients était de 36,30 ± 15,38 ans, avec un sex-ratio de 0,31. Les pathologies endocriniennes étaient dominées par l'hypogonadisme (32%), et par l'hypercorticisme (19%), suivis par l'hyperthyroïdie (11%). Le T-score moyen au niveau du rachis et au niveau du fémur était respectivement de -1,65% ± 1,88 DS, et -0,85 ± 1,70 DS. L'atteinte de la densité minérale osseuse a été plus fréquente au niveau du rachis (61,9%). L'ostéoporose a été surtout constatée au cours des hypogonadismes, hypercorticismes, hyperthyroïdies et hyperparathyroïdies. Néanmoins elle a été observée également au cours des hypothyroïdies et d'autres étiologies non connues pour être responsables d'une ostéoporose. Ce travail nous a ainsi conduits à situer l'intérêt de rechercher systématiquement l'atteinte osseuse devant toute endocrinopathie susceptible de provoquer une atteinte rhumatologique. PMID:26985276

    With the advent into the 20th century whole world has been facing the common dilemma of Terrorism. The suicide attacks on US twin towers 11 Sept. 2001, Train bombings in Madrid Spain 11 Mar. 2004, London bombings 7 Jul. 2005 and Mumbai attack 26 Nov. 2008 were some of the most disturbing, destructive and evil acts by terrorists in the last decade which has clearly shown their evil intent that they can go to any extent to accomplish their goals. Many terrorist organizations such as al Quaida, Harakat ul-Mujahidin, Hezbollah, Jaish-e-Mohammed, Lashkar-e-Toiba, etc. are carrying out training camps and terrorist operations which are accompanied with latest technology and high tech arsenal. To counter such terrorism our military is in need of advanced defense technology. One of the major issues of concern is secure communication. It has to be made sure that communication between different military forces is secure so that critical information is not leaked to the adversary. Military forces need secure communication to shield their confidential data from terrorist forces. Leakage of concerned data can prove hazardous, thus preservation and security is of prime importance. There may be a need to perform computations that require data from many military forces, but in some cases the associated forces would not want to reveal their data to other forces. In such situations Secure Multi-party Computations find their application. In this paper, we propose a new highly scalable Secure Multi-party Computation (SMC) protocol and algorithm for Defense applications which can be used to perform computation on encrypted data. Every party encrypts their data in accordance with a particular scheme. This encrypted data is distributed among some created virtual parties. These Virtual parties send their data to the TTP through an Anonymizer layer. TTP performs computation on encrypted data and announces the result. As the data sent was encrypted its actual value can’t be known by TTP

    The aim of this work is to develop a functional wood incorporating, in its surface, physical and chemical properties that meet society demand. For instance: fire resistance, magnetic electrical conduction (metal-wood particles), antibacterial reaction (copper-wood), anti-pollution (zeolite-wood), dry coloring, reflective effects (minerals-wood). As part of the research on wooden materials, the technique of "JAZOLTHOP1" driving micrometric particles before combining them and moving in supersonic speeds was used in the framework of enriching a wooden substrate. Various tests were conducted on two wooden materials (fir and ash tree) submitted to four typologies of particles (steel shot, garnet, corundum and glass beads). The surfaces of the test samples were machined beforehand for a use of conventional smooth quality, thus defining a reference surface before incorporation. The enriched samples were characterized by using two optical techniques; firstly a surface technique through macroscopy Leica 110X ZP, then a volume technique through tomography2. Subsequently, volume simulations (wood-inclusions) were implemented to study the thermal transfer. The obtained results showcase the existence of certain set conditions to reach the critical fluency of incorporation and to localize the enrichment on a parallel plan to the sample surface. The results show also the influence of particles concentration and the kind of the chosen wood on the final composite matrix/particle media.

    Le ballon de contre pulsion intra-aortique (BCPIA) est fréquemment utilisé en chirurgie cardiaque, comme moyen d'assistance circulatoire en cas de bas débit cardiaque. Il est d'intérêt clinique de déterminer les facteurs pronostiques chez les patients porteurs d'un BCPIA en chirurgie cardiaque, et qui restent un sujet rarement élucidé dans la littérature. L'objectif de notre travail est de déterminer les facteurs prédictifs de morbi-mortalité chez les patients sous ballon de contre pulsion intraortique en périopératoire d'une chirurgie cardiaque. Il s'agit d'une étude rétrospective portant sur l'ensemble des patients opérés en chirurgie cardiaque sous circulation extracorporelle, et ayant bénéficiés de la mise en place d'un ballon de contre pulsion intra-aortique en périopératoire, au service de chirurgie cardiovasculaire de l'Hôpital Militaire Mohamed V de Rabat, entre le mois de janvier 2005 et le mois d'aout 20014. Soixante dix patients ont été inclus dans notre étude. En analyse univariée l'âge, la dyspnée de stade III et IV, l'insuffisance cardiaque, la présence d'un infarctus du myocarde, d'une coronaropathie mono et bitronculaire, les anomalies du doppler de trons supra-aortique et du membre inférieur, le caractère urgent de la chirurgie, la durée de la circulation extracorporelle, l'instabilité hémodynamique postopératoire, le saignement et l'insuffisance rénale postopératoire étaient statistiquement associés à une mortalité postopératoire élevée. La dyskinésie préopératoire et la sortie de circulation extracorporelle sous drogues étaient associées à une morbidité globale élevée. En analyse multi variée, seule l'âge, constituait un facteur de risque indépendant de mortalité dans notre série avec un Odds Ratio (OR): 1,89 ; un Intervalle de Confiance (IC) 95% de (1,52-4,97) et un p =0,045.

Rimi+ * Filière de Formation en Topographie Institut Agronomique et Vétérinaire Hassan II B.P. 6202 Rabat-Instituts MAROC + Département de la Physique du Globe Université Mohammed V Rabat MAROC This study focus on the use of the geodetic spatial technique GPS for geodynamic purposes generally in the Western Mediterranean area and particularly in Morocco. It aims to exploit this technique first to determine the geodetic coordinates on some western Mediterranean sites. And also this technique is used to detect and to determine movements cross the boundary line between the two African and Eurasian crustal plates on some well chosen GPS-Geodynamics sites. It will allow us also to estimate crustal dynamic parameters of tension that results. These parameters are linked to deformations of terrestrial crust in the region. They are also associated with tectonic constraints of the study area. The usefulness of repeated measurements of these elements, the estimate of displacements and the determination of their temporal rates is indisputable. Indeed, sismo-tectonique studies allow a good knowledge of the of earthquake processes, their frequency their amplitude and even of their prediction in the world in general and in Moroccan area especially. They allow also contributing to guarantee more security for all most important management projects, as projects of building great works (dams, bridges, nuclear centrals). And also as preliminary study, for the most important joint-project between Europe and Africa through the Strait of Gibraltar. For our application, 23 GPS monitoring stations under the ITRF2000 reference frame are chosen in Eurasian and African plates. The sites are located around the

    Background Despite the upsurge in support and intervention of donor agencies in HIV care and treatment programing in Sub-Sahara African, antiretroviral (ART) programs are still confronted with access and coverage challenges which influence enrolment of new patients. This study investigated the validity of point of care BD FACSPresto™ CD4 analyzer for CD4+ cell count, overall agreement, correlation, sensitivity, and specificity in comparison to a reference standard flow cytometry method. We also assessed the feasibility of use among non-laboratorians. Methods Blood samples from 300 HIV infected individuals were analyzed for CD4+ T cell and CD4%, using finger prick capillary sample from 150 PMTCT clients and 150 ART clients at Murtala Mohammed Specialist Hospital, Kano, Nigeria. Their venous samples were compared on a flow cytometry reference method using BD FACSCount CD4+ count system. The accuracy of the BD FACSPresto machine in comparison to BD FACSCount was evaluated. Statistical analysis was carried out using STATA (version 12). Bland-Altman method and correlation analysis were used to analyze agreement between both measurements. In addition, sensitivity and specificity of both measurements were determined. Statistical significance was set at p-value <0.05. Results The mean bias and limit of agreement for CD4+ count between BD FACSPresto and BD FACS count machine were 7.49 (95% CI: 2.44 to 12.54) and -8.14 to 96.39 respectively. Further analysis revealed close agreement between BD FACSPresto and BD FACSCount with no significant difference between the two methods (p = .0.95). Using a threshold of 500 cells/μL, sensitivity and specificity of BD FACSPresto were 95.1% and 97.1% respectively, compared to BD FACSCount. There was no statistically significant difference in the misclassification between BD FACSPresto and BD FACSCount results (p = 0.23). Furthermore, sensitivity and specificity were similar when BD FACSPresto machine was operated by a nurse or

    Diabetes is a public health problem. Its global prevalence was 2.8% in 2000 and it will reach 4.4% in 2030 to be 366 million diabetics. In Morocco, this true "epidemic" affects 6.6% of the population. Many epidemiologic studies have shown that patients with diabetes are more susceptible to depression. Diabetes and depression align in a non-accidental way and complicate one another. We report a cross-sectional study conducted in association with the endocrinology department of the Mohammed VI university hospital during the period spread between April and September 2006. The aim was to evaluate the prevalence of depressive disorders in patients with diabetes and to describe their sociodemographic and clinical profile. The study included 187 patients. The scales used were the Mini International Neuropsychiatric Interview (MINI) and Hamilton's depression. Sociodemographics and diabetic characteristics were evaluated by self-questionnaire. The average age of our patients was 53±14 years and the percentage of females was high: 71.2%. Diabetes type 2 was the most representative (85.6%), diabetes type 1 (11.8%) and gestational diabetes (2.7%). Half of diabetics were treated with an association of healthy dietary measures (MHD) and oral anti-diabetics; 31.6% were under MHD and insulin therapy; 33.2% of patients had acute complications and 43.5% had degenerative complications. Only 11 patients (5.9%) had antecedents of depression. The prevalence of major depressive episode was 41.2%; 27.8% of patients suffered from dysthymia and 21.9% from double depression. Hamilton's depression scale indicates that all depressed patients had mild depression (total of 17 items from 8 to 17). Major depressive episode and dysthymia were frequent in out patients. Dysthymia was predominant in diabetic patients in the 46 to 55 years age group, never been schooled and without any comorbidity. The vast majority of patients with EDM had type 2 diabetes with 89.6%, 7.8% type 1 diabetes and 2

    The potential for chemicals to adversely affect human immunologic health has traditionally been evaluated in rodents, under laboratory conditions. These laboratory studies have generated valuable hazard identification and immunotoxicologic mechanism data; however, genetically diverse populations exposed in the wild may better reflect both human exposure conditions and may provide insight into potential immunotoxic effects in humans. In addition, comparative studies of species occupying reference and impacted sites provide important information on the effects of environmental pollution on the immunologic health of wildlife populations. In this symposium overview, Peter Hodson describes physiological changes in fish collected above or below the outflows of paper mills discharging effluent from the bleaching process (BKME). Effects attributable to BKME were identified, as were physiological changes attributable to other environmental factors. In this context, he discussed the problems of identifying true cause and effect relationships in field studies. Mohamed Faisal described changes in immune function of fish collected from areas with high levels of polyaromatic hydrocarbon contamination. His studies identified a contaminant-related decreases in the ability of anterior kidney leukocytes to bind to and kill tumor cell line targets, as well as changes in lymphocyte proliferation in response to mitogens. Altered proliferative responses of fish from the contaminated site were partially reversed by maintaining fish in water from the reference site. Peter Ross described studies in which harbor seals were fed herring obtained from relatively clean (Atlantic Ocean) and contaminated (Baltic Sea) waters. Decreased natural killer cell activity and lymphoproliferative responses to T and B cell mitogens, as well as depressed antibody and delayed hypersensitivity responses to injected antigens, were identified in seals fed contaminated herring. In laboratory studies, it was

    Les implants cochléaires sont des prothèses électro-acoustiques qui ont pour rôle de pallier une déficience bilatérale de l'oreille interne, qu'elle soit profonde ou sévère, acquise ou congénitale. Nous rapportons l'expérience du service d'Oto-rhino-laryngologie et de chirurgie cervico-faciale de l'hôpital universitaire Mohammed VI de Marrakech, dont l'objectif est d'évaluer l'implantation cochléaire et de préciser les facteurs influençant les résultats dans notre pratique. Le profil APCEI a été utilisé pour évaluer les résultats orthophoniques. Il s'agit d'une étude rétrospective étalée sur une période de 7 ans (Décembre 2007 à Décembre 2014). Durant cette période; 54 patients ont été implantés et suivient dans notre formation. Il s'agit de 30 filles et 24 garçons atteints d'une surdité sévères à profonde bilatérale, dont 48 enfants avaient une surdité pré-linguale. L'âge moyen d'implantation cochléaire pédiatrique était de 5,15 ans. L'implantation était unilatérale chez tous les patients. L'intervention était suivie par des réglages et une rééducation orthophonique régulière. L'évaluation était réalisée par la même équipe chaque mois durant les premiers 6 mois, puis tous les 6 mois. La durée moyenne de suivi était de 30,86 mois. Tous les patients ont tiré un bénéfice de leurs implants avec une variabilité interindividuelle. Les bons résultats étaient corrélés à l'implantation précoce, à un investissement parental important et au un bon suivi de la rééducation orthophonique. L'implantation cochléaire a révolutionnée la prise en charge de la surdité profonde et sévère. C'est une technique sûre, efficace lorsqu'elle s'adresse à des populations correctement sélectionnées.

    Before the establishment of demography as a scientific discipline, Arab writers had developed and utilized demographic principles in their scientific writings about geography. Early Arab advances in demographic thought, especially in regard to population distribution, were discussed. (All dates were given as anno Hegira (AH), i,e., the dates accord with the Muslim calendar in which the 1st year coincides with Mohammed's flight from Mecca in 622). As early as the 2nd century Hegira, a number of historical writers mentioned population movements, and Arab rulers conducted censuses of conquered areas; however, it was not until the 3rd century Hegitpra that population distribution was treated in a scientific manner. During that century Al-Jahiz made the 1st scientific observation when he noted the importance of enviromental influences on the distribution and disposition of people, and Al-Razi noted that when people came together in large groups they divided up functions between themselves, i.e., he identified the division of labor hundreds of years before Adam Smith. Between 300-900 AH many other writers utilized demographic principles in their writings, but the major contributions to demographic thought were made by Ibn Khaldun (732-800AH) and elaborated by his followers Al-Maqrizi (766-845 AH) and Ahmed Ibn Al-Dalji (770-838 AH). Although scholars recognize the contributions of Ibn Khaldun to sociology and philosophy, little attention is paid to his writings in demography. Ign Khaldun was the 1st to recognize the importance of examining socioeconomic development from a demographic perspective. Many of his writings dealt with the impact of population on socioeconomic factors. Ibn Khaldun estimated that only 1/4 of the world's area was inhabited; modern day estimates are that 30% of the earth's surface is inhabited. He divided the inhabited areas of the then known earth into 7 regions and observed that the population was distributed unevenly in these areas. In his

    Self-mutilating behaviour is expanding, especially among adolescents and patients with a psychiatric disorder. We have tried to describe the self-mutilating behaviour in Moroccan inpatients of the psychiatric department of Mohammed V Military Hospital of Rabat, through a prospective and descriptive longitudinal study over a period of four months, based on a questionnaire prepared according to the literature data to allow discussing its results. The rate of participation was 90.4%, or 19 patients. All patients were male. The age of onset of self-injury was between 14 and 62 years with an average of 26.3 years. Only two patients had an age of onset in adolescence, before age 20, the majority (57.8%) in a young adult age. Eight patients (42.1%) report having experienced physical abuse while only four patients were sexually abused, especially by relatives. The number of episodes varied from one episode in twelve cases (63.15%), to seven cases (37%) with repetitive self-mutilation. The most common type of self-injury was cuts (16 cases), twelve patients inflicted burns, and two patients inflicted fist blows. The forearm was the most common location. All patients were unable to resist the pressing need to self-harm after various reasons, often in a relational or professional frustration state. The use of concomitant substances to self-mutilation was reported in nine episodes, alcohol in seven episodes (24.1%) and cannabis in three episodes (10.3%). Only five patients reported receiving medical care for physical consequences of self-harm. Only two patients underwent a psychiatric care following their self-mutilation and admitted to our service. Personality disorders was the psychiatric disorder most diagnosed in our sample, followed by mood disorders. Borderline personality disorder was the pathological personality disorder most commonly diagnosed in our study with nearly two thirds of cases, followed by antisocial personality.

    and volcanoes). This meteoric water infiltrates quickly through porous volcanic rocks and is stored in aquifers and released slowly. As a component of the rift hydrologic system, wetlands appear to be reliable indicators of rainfall fluctuations on both Milankovitch and sub-Milankovitch time scales. Wetland sediments are commoner in the geologic record during times of higher rainfall and are less common during drier periods. Modern arid rift wetland records are peats and organic-rich clay deposits that contain eolian-transported mineral matter, plant remains (e.g. roots, stems) pollen, phytoliths, diatoms, root casts, charcoal, carbonate and manganese-rich nodules, as well as copious evidence of bioturbation (plants and invertebrates to large vertebrate trampling). Older (Pleistocene) deposits that retain little original organic matter and plant remains are generally silicified, but otherwise the record is similar to modern wetlands. Records from Olduvai Gorge (1.85-1.75 Ma) contain springs and wetlands associated with stone tools. On shorter time-frames, a drought occurred during the Medieval Warm Period (MWP) and higher rainfall in East Africa during the Little Ice Age (700 BP) led to higher lake levels of Lake Naivasha and Lake Turkana (Mohamed et al. 1995; Verschuren et al. 2000) and the simultaneous initiation and expansion of Loboi Swamp in Baringo-Bogoria basin (Ashley et al. 2004). Therefore, a wetland as an indicator of climate change even on millennial-scale cycles is a viable option to lakes as paleoclimatic indicators in arid, low-latitude continental settings. Groundwater reservoirs provide a perennial water source for plants and animals (including hominins) in what might otherwise be a parched environment.

    confirmed by future Hubble observations, this finding will have a far-reaching impact on stellar evolutionary models," says Heydari-Malayeri. "That's because the Wolf-Rayet candidate is fainter than other such stars in that galaxy, in contrast with the predictions of these models." Hubble's resolution allows astronomers to pinpoint 50 separate stars tightly packed in the nebula's core within a 10 light-year diameter -- slightly more than twice the distance between Earth and the nearest star to our sun. The closest pair of stars is only one-third of a light-year apart. Before the Hubble observations, N81 was simply dubbed, "The Blob" because its features were indistinguishable by other telescopes. The Hubble observations of N81 were conducted by the European astronomers Mohammed Heydari-Malayeri (Paris Observatory, France) and co-investigators Michael Rosa (Space Telescope-European Coordinating Facility, European Southern Observatory, Germany), Hans Zinnecker (Astrophysics Institute, Potsdam, Germany), Lise Deharveng (Marseille Observatory, France), and Vassilis Charmandaris (Paris Observatory). Their work will be shortly submitted for publication in the European journal Astronomy and Astrophysics. The Hubble Space Telescope is a project of international cooperation between ESA and NASA.

    Despite the upsurge in support and intervention of donor agencies in HIV care and treatment programing in Sub-Sahara African, antiretroviral (ART) programs are still confronted with access and coverage challenges which influence enrolment of new patients. This study investigated the validity of point of care BD FACSPresto™ CD4 analyzer for CD4+ cell count, overall agreement, correlation, sensitivity, and specificity in comparison to a reference standard flow cytometry method. We also assessed the feasibility of use among non-laboratorians. Blood samples from 300 HIV infected individuals were analyzed for CD4+ T cell and CD4%, using finger prick capillary sample from 150 PMTCT clients and 150 ART clients at Murtala Mohammed Specialist Hospital, Kano, Nigeria. Their venous samples were compared on a flow cytometry reference method using BD FACSCount CD4+ count system. The accuracy of the BD FACSPresto machine in comparison to BD FACSCount was evaluated. Statistical analysis was carried out using STATA (version 12). Bland-Altman method and correlation analysis were used to analyze agreement between both measurements. In addition, sensitivity and specificity of both measurements were determined. Statistical significance was set at p-value <0.05. The mean bias and limit of agreement for CD4+ count between BD FACSPresto and BD FACS count machine were 7.49 (95% CI: 2.44 to 12.54) and -8.14 to 96.39 respectively. Further analysis revealed close agreement between BD FACSPresto and BD FACSCount with no significant difference between the two methods (p = .0.95). Using a threshold of 500 cells/μL, sensitivity and specificity of BD FACSPresto were 95.1% and 97.1% respectively, compared to BD FACSCount. There was no statistically significant difference in the misclassification between BD FACSPresto and BD FACSCount results (p = 0.23). Furthermore, sensitivity and specificity were similar when BD FACSPresto machine was operated by a nurse or laboratory scientist, there was no

    In Tunisia, the phenomenon of self-immolation has increased dramatically since the self-burn of Mohamed Bouazizi which occurred on 17 December 2010. The aim of our study was to compare the casualties' profile of suicide by self-immolation before and after the Tunisian Revolution over a period of 10 years (2006-2015). We conducted a retrospective review including all the cases of self-immolation suicides that occurred in Northern Tunisia five years before and five years after the January 2011 Revolution. We excluded cases of self-immolations committed in governorates other than the north of Tunisia as well as casualties of accidental or criminal burns and those where the context could evoke suicidal immolation but the self-inflicted nature has not been confirmed. The study sample was subdivided in two groups according to the Revolution date: before the Revolution (2006-2010) and after the Revolution (2011-2015). We compared for each group data related to the age, gender, marital status, employment, mental disease history, previous suicide attempts and threats, place of suicide and its motive, the type of fire accelerator, the hospitalization and the average body surface area burned. The number (n=48/24.5% before 2011) of suicide by self-immolation has tripled during the post-revolution period (2011-2015) with a stable trend. The average age (35.6±13.4) has not changed. The male remained predominant before and after the Revolution (sex ratio of respectively 1.67 and 3.23). Marital status (victims being single in n=81 cases/41.3%) and the employment (unemployed in n=128/65.3%) of the casualties have not changed either after 2011. Fewer cases with psychiatric history were reported (n=21/43.7% before against n=52/35.1% after). Self-immolation increased in public places (n=9/18.7% before against n=50/33.8% after) and in an administration (n=2/4.2% before against n=19/12.8% after). More suicides after 2011 were due to financial problems (n=2/4.2% before against n=30

    Les pyélonéphrites aigues gravidiques (PNAg) sont fréquentes et peuvent avoir des conséquences maternelles et fœtales graves. Le but de notre étude était de déterminer les facteurs prédictifs cliniques, biologiques et radiologiques qui permettent de se limiter au traitement médical ou d'associer un drainage de la voie excrétrice supérieure dans la prise en charge des PNAg. Nous rapportons, de façon rétrospective une série de 26 cas dans les services d'Urologie et de Gynécologie de l'Hôpital Militaire d'Instruction Mohamed V de Rabat (Maroc) sur une période allant du 1er Janvier 2010 au 30 Aout 2012. Toutes les patientes avaient une PNAg symptomatique objectivée par l'ECBU et/ou l’échographie rénale. La fréquence de la pyélonéphrite aigue gravidique par rapport aux pyélonéphrites aigues en général a été de 27,95% avec une prédominance chez les primipares de 53,84%. Son pic de fréquence se situe à 73,08% pour les gestantes âgées de 19 à 37 ans ainsi qu'au troisième trimestre (77%) de la grossesse. La triade clinique fièvre, lombalgie, troubles mictionnels et l’échographie rénale sont les éléments importants du diagnostic. L'antibiothérapie probabiliste a été débuté d'emblée et adaptée en fonctions des résultats de l'examen cytobactériologique des urines. Sa durée est de trois à six semaines en fonction de l’évolution clinique. La protéine C réactive est un marqueur de progression de la maladie ou de l'efficacité thérapeutique. Les principaux facteurs prédictifs du drainage de la voie excrétrice supérieure sont: persistance de la symptomatologie clinique, du syndrome infectieux et des anomalies visibles à l’échographie rénale ainsi que l'altération de la fonction rénale. La montée de la sonde JJ est le principal traitement urologique.

    considered as life threatening events. Persian history of epilepsy, except from the 6th century Zoroastrian "Avesta" document, lacks the written or spoken medical heritage untill the 7th century A.D. and the Arabic conquest of the entire Moslem world. On the other hand, Islamic medicine should be freed from the simple prejudice that the Moslem authors were only the translators of Greek medicine; contrary to such a view, their work contains a high degree of individuality. Although Mohammed introduced a lot of novelty into medicine, Khoran and the Sayings do not explicitly refer to epilepsy. Of importance is to notice that Moslem medicine did not have demons in the "repertoire" of direct causes of epilepsy. The causes and the cures of epilepsy were more magic-mystical and occult in nature, which is reminiscent of the European, as well as Serbian Middle age attitudes. Avicenna recognized difference between children and adult epilepsy. He considered insomnia and afternoon siesta as well as intensive sounds and light to be a provocative factors, whereby we see that at least empirically he knew of sleep (deprivation), startle and reflex epilepsy. The XIII century invasion of Mongols brought about the recession in Moslem Medicine; it recovered only in the XVIII century under the strong influence of European medicine handed over to us through Jewish doctors of various nationalities. The story of the China history of epilepsy has its debut approximately in the 8th century B. C. Medical texts from this period name epilepsy "Dian" and "Xian" which meant "the falling sickness" and "convulsions", respectively. Chinese medical terminology often interchangeably used the words "mania", "madness" and "psychosis" for "epilepsy" which, aside from a prominent language barrier, brings additional confusion. Although Chinese documents gave the first description of the grand mal epileptic attack already in the 8th century B. C. (ABSTRACT TRUNCATED)

    Nous rapportons les résultats de la chirurgie coronaire chez une population de coronariens diabétiques opérés sous circulation extra-corporelle dans le service de chirurgie cardiaque de l'hôpital militaire d'instruction Mohammed V de Rabat. C'est une étude rétrospective menée entre Janvier 2008 et Février 2012 (4 ans), portant sur 103 patients diabétiques consécutifs opérés pour pontage coronaire. L’âge moyen des patients était de 61±8,7ans (37-82ans) avec un sexe ratio (H/F) de 3,9. Tous les patients diabétiques de type 2 et sous traitement anti-diabétique ont été inclus dans cette étude. La sténose du tronc commun gauche était présente chez 26,2% des patients et 53,4% étaient tritronculaires. Quatre-vingt patients (78,6%) étaient insulino-nécessitant, l'Euro-score moyen était de 1,63±1% et le nombre moyen de pontage de 2,3±0,7. Les durées moyennes de la circulation extra-corporelle et du clampage aortique étaient respectivement de 134,4 ± 42 min et 76 ± 28 min. La mortalité hospitalière était de 2 décès (1,9%), les durées moyennes de ventilation artificielle, du séjour en réanimation et du séjour postopératoire étaient respectivement de 7h (5-16h), 48h (42-52h) et 15,6 ± 8,6 jours. Les complications postopératoires étaient l'infarctus du myocarde, l'infection de paroi, la médiastinite et le bas débit cardiaque chez respectivement 1,9%, 10,7%, 3,9% et 1,9% des patients. Il ressort de notre étude, que les facteurs prédictifs d'infection post opératoire étaient la durée de ventilation artificielle (p = 0,002), la durée de la circulation extra-corporelle (p < 0,001) en plus du tabac (p = 0,004) et de l'obésité (p = 0,005).

  13. Behavior and Microstructure in Cryomilled Aluminum alloy Containing Diamondoids Nanoparticles

    Hanna, Walid Magdy

    Aluminum (Al) alloys have been the materials of choice for both civil and military aircraft structure. Primary among these alloys are 6061 Al and 5083 Al, which have used for several structural applications including those in aerospace and automobile industry. It is desirable to enhance strength in Al alloys beyond that achieved via traditional techniques such as precipitation hardening. Recent developments have indicated strengthening via grain refinement is an effective approach since, according the Hall-Petch relation, as grain size decreases strength significantly increases. The innovate techniques of severe plastic deformation, cryomilling, are successful in reefing grain size. These techniques lead to a minimum grain size that is the result of a dynamic balance between the formation of dislocation structure and its recovery by thermal processes. According to Mohamed's model, each metal is characterized by a minimum grain size that is determined by materials parameters such as the stacking faulty energy and the activation energy for diffusion. In the present dissertation, 6061 Al and 5083 Al were synthesized using cryomilling. Microstructural characterization was extensively carried out to monitor grain size changes. A close examination of the morphology of the 6061 Al powder particles revealed that in the early milling stages, the majority of the particles changed from spheres to thin disk-shaped particles. This change was attributed to the high degree of plastic deformation generated by the impact energy during ball-powder-ball collisions. Both transmission electron microscopy (TEM) and X-ray diffraction (XRD) were used to monitor the change in grain size as a function of milling time. The results of both techniques demonstrated a close agreement with respect to two observations: (a) during cryomilling, the grain size of 6061 Al decreased with milling time, and (b) after 15 h of milling, the grain size approached a minimum value of about 22 nm, which is in

    Les traumatismes graves du rein de grade III, IV et V selon la classification de l'Amercan Society for Surgery For Trauma (ASST) sont plus rares et se retrouvent dans 5% des cas en moyenne. Leur prise en charge est souvent délicate, nécessitant alors des centres expérimentés dotés de moyen adéquats d'imagerie (scanner spiralé). Cependant, durant ces dernières années, la prise en charge de ces traumatismes a évolué vers une attitude de moins en moins chirurgicale grâce à l’évolution des techniques de la radiologie interventionnelle, de l'endourologie et des moyens de surveillance aux urgences et de réanimation. L'objectif de cette étude est d’évaluer notre expérience dans la prise en charge des traumatismes rénaux de haut grade. Notre étude rétrospective porte sur 25 cas de traumatismes grave du rein de grade III, IV et V selon la classification de l'ASST, colligés entre Janvier 2002 et Juin 2009 au service d'urologie du centre Hospitalier Universitaire Mohammed VI, Université Cadi Ayyad de Marrakech, Maroc. Nous avons étudié les données épidémiologiques, les signes cliniques et biologiques à l'admission (état de choc hémorragique, taux d'hémoglobine), les données radiologiques (échographie et scanner), les lésions associées, la prise en charge thérapeutique et les complications. L’âge moyen de nos patients était de 24,9 ans 15 et 58 ans, avec une prédominance masculine (sex-ratio = 7, 3). Le rein droit était intéressé dans 15 cas (60%). Le traumatisme rénal était fermé dans 15 cas, et ouvert par arme blanche dans 10 cas. Huit patients se sont présentés en état de choc hémorragique (32%). Une anémie inférieur à 10g /100ml a été observée dans 10 cas (40%). L'uroscanner fait systématiquement à l'admission a retrouvé un grade III (10 cas), grade IV (13 cas) et grade V (2 cas).

    laboratories. Applications: 1. Corrosion: Electron flow is often part of the corrosive process, and several studies were done in concert with this proposal with regard to the ability of EET-capable bacteria to enhance, inhibit, or detect corrosion. These included using EET-capable bacteria to detect corrosion in its earliest stages [5], to use corrosion-causing bacteria for the study of the microbe/mineral interface during corrosion [1], and to study the groups of microbes involved with corrosion of natural systems [19]. 2. Bioenergy and microbial fuel cells: The production of electricity by Shewanella was shown early in this program (several years ago) to be dependent on the genes for extracellular electron transport (EET), and applied work involved the testing of various strains and conditions for the optimization of current production by the shewanellae [11,14,16]. 3. Identification of shewanellae strains: Based on similarities seen in genomic comparisons, a rapid method was employed for distinguishing between shewanellae strains [17]. Interactions with other laboratories: This grant was an extension of a grant involving the so-called ?Shewanella Federation?, and as such, a number of our publications were joint with other members of this group. The groups included: 1. Pacific Northwest Laboratories ? 2. Oak Ridge National Labs 3. Michigan State University 4. University of Oklahoma 5. Naval Research Laboratory, Washington DC 6.

    with 200 mM NaCl for 1, 6 or 12 hours, and the soluble apoplast proteins were extracted and for differential analysis compared to untreated controls by 2-D DIGE saturation labeling techniques. 122 significant changed (1-ANOVA p-value <0.05) spots are identification by LC-MS/MS, and 117 spots representing 69 proteins have been identified. Of these, 37 proteins are apoplastic proteins according to bioinformatic analysis. These proteins are mostly involved in carbohydrate metabolism, oxido-reduction, protein processing and degradation. According to the results of functional categories and cluster analysis, a stress response model of apoplastic proteins has been proposed. These dates indicate that apoplast is an important portion in plant stress signal reception and response. LC-MS/MS data was provided by the Bio-Organic Biomedical Mass Spectrometry Resource at UCSF (A. L. Burlingame, Director) supported by the Biomedical Research Technology Program of the NIH National Center for Research Resources, NIH NCRR P41RR001614 and NIH NCRR RR019934.

Mohammed2, N. Taouatas2, Iain D G Campuzano1, and A. J. R. Heck2 1Waters Corporation, MS Technologies Center, Manchester, United Kingdom; 2Department of Biomolecular Mass Spectrometry, Utrecht University, Utrecht, The Netherlands Recently, Lys-N was introduced as a near ideal enzyme for proteomics workflows that involve electron transfer dissociation (ETD) or MALDI-CID. Lys-N peptides with a single basic residue, Indiana, USA combination with ETD, have a clear advantage for spectral interpretation due to peptide tandem mass spectra consisting of almost exclusively c-type fragment ions. Furthermore, the combination of Lys-N and SCX enables facile fractionation/enrichment of acetylated, phosphorylated peptides with a single basic residue and non
