description: BackgroundThe surgical site infection (SSI) rate after Cesarean delivery (CD) is considered one of the key performance indicators, not only for developing and under-developed countries but also for developed nations. SSIs not only increase patients’ morbidity and mortality rates, but also lay a huge economic burden. In our hospital, the SSIs after CD were noted to increase in 2016 and first quarter of 2017. One of the methods implemented for SSI reduction included identifying modifiable risk factors.MethodsA case-control study was conducted at a secondary hospital in Qatar after institutional approval. Retrospective analysis of risk factors and microbiological spectrum was carried out in women who delivered by Cesarean Section between 2017-2020. Women who did not develop SSIs were taken as control group and selected with a blind sampling technique. The risk assessment was compared with a control population. The Odds’ ratio was calculated for statistical analysis of results. A look into the causative organism was performed to assess if the antibiotic prophylaxis was appropriate.Results8,372 women delivered by Cesarean section during the study timeframe. Out of these 1.51% developed SSIs. Nearly two-thirds had superficial wound infections. 87% of these cases were diagnosed between 8-28 days of CD. Gestational diabetes, anemia, body mass index >30kg/m2, prolonged rupture of membranes >24 hours, and chorioamnionitis were identified as risk factors (p<0.05) (Figure 1). The most common organisms for SSIs were Staphylococcus aureus (25.58%), E. coli (27.13%) and Klebsiella pneumonia (10.08%). Multiple drug-resistant organisms were isolated in 17.83% of cases.ConclusionThis study provides baseline levels for SSI after CD across several different patient subgroups. SSIs with multiple drug-resistant organisms were significantly high. Physicians should give special attention to modifiable risk factors and antibiotic stewardship to decrease the risk of SSI and improve patient outcomes.

description: Reconstructing complex structures from planar cross-sections is a challenging problem, with wide-reaching applications in medical imaging, manufacturing, and topography. Out-of-the-box point cloud reconstruction methods can often fail due to the data sparsity between slicing planes, while current bespoke methods struggle to reconstruct thin geometric structures and preserve topological continuity. This is important for medical applications where thin vessel structures are present in CT and MRI scans. This paper introduces CrossSDF, a novel approach for extracting a 3D signed distance field from 2D signed distances generated from planar contours. Our approach makes the training of neural SDFs contour-aware by using losses designed for the case where geometry is known within 2D slices. Our results demonstrate a significant improvement over existing methods, effectively reconstructing thin structures and producing accurate 3D models without the interpolation artifacts or over-smoothing of prior approaches.

description: Ability of water hyacinth to live in different basins (lakes and lagoons) tropical regions makes this species an adventitious by excellence. Its high multiplication capacity poses enormous problems to the fisheries sector due to the dense carpet that it forms on the surface of the water thus preventing navigation, the penetration of light, the dissolution of oxygen and causing death of some aquatic organisms. This plant strictly subject to freshwater is considered as aquatic species among the most harmful in the world because of its excellent reproductive power. Salinity generally limited its development in coastal and estuarine areas. The present study examines the development of water hyacinth subjected to a salinity gradient. Experiments were conducted in buckets of 15 L plastic at the rate of ten (10) treatments including one (01) control, repeated four times.The salinity gradient consisted of ten levels: 0 g/L; 5 g/L; 9 g/L; 13 g/L; 15 g/L; 18 g/L; 21 g/L; 24 g/L; 27 g/L and 30 g/L. The results of these studies showed, firstly, that for the direct supply of salt in the Middle, water hyacinth can’t survive at a salinity of the environment greater than or equal to 9 g/L. On the other hand, the effective salinity for transfoliaire spraying of Eichhornia crassipes is 24 g/l.

description: Historical studies of the shoreline are first used to determine the long-term trend of shoreline evolution. Originally used for a purely "theoretical" purpose, they have, since the end of the 1980s, become more and more practical applications, especially for the assessment of the impacts of coastal engineering works, the determination of the volumes of sand necessary for the artificial feeding of the beaches and the estimation of future changes of the shore line. The dynamics of soft coasts are complex (Salomon, 2008) and are very often organized over areas several kilometers long. This technique of multi-date analysis of aerial photographs is one of the most used to observe coastal processes. The reliability of the results obtained (Crowel et al., 1991, Dolan et al, 1991) leads a large number of researchers to use these aerial photographs, whose examination allows a global and retrospective view of the phenomena. The purpose of this study is to retrace the morphological evolution of the Marchica shoreline between 1954 and 2003 while: (i) identifying the trend of shoreline shifts; and (ii) assessing rates of erosion or erosion. increase by sector and by period. This will be confronted with the results produced by SOGREAH through GENESSIS which is a purely digital model. Our results will also be compared with the work done in the ACCMA project (2009).

description: In the tomographic configurations based on the muon scattering, the angular variation with respect to the kinetic energy indirectly brings forth the ability to coarsely predict the kinetic energy by using the deflection angle owing to the detector layers. Nevertheless, the angular deviation due to the detector components is expected to be minuscule in addition to a relatively high uncertainty in the case of the plastic scintillators. In the present study, we contrast our current tomographic prototype, which consists of the detector layers manufactured from polyvinyl toluene besides a detector accuracy of 1 mrad, with an alternative hodoscope scheme containing stainless steel layers by aiming to investigate the three-group energy structure. Initially, we determine the average deflection angles together with the corresponding standard deviations for our present setup as well as for the alternative scheme by means of the GEANT4 simulations. In the second place, we express a brace of misclassification probabilities founded on the standard deviations where the first procedure assumes a linear finite approximation, whereas the latter approach rests on a positively defined modified Gaussian distribution. Upon our simulation results, we demonstrate that the introduced stainless steel layers in the proposed hodoscope setup do not only serve to augment the average deflection angles, but they also diminish the misclassification probabilities, therewith reducing the classification uncertainty apart from an improved detection performance.

description: L'objet de cette étude est d’analyser l’impact des mésalignements de taux de change réel sur l’économie nationale. Pour cela, on a eu recours aux résultats de la méthode CGER du FMI selon lesquels l’évolution en moyenne géométrique, du mésalignement, durant la période 2006-2011, est de l’ordre de 2,5%. Ainsi, les études des mésalignements en MEGC sont reconnues des meilleures, pour évaluer les effets des mésalignements sur la stabilité macroéconomique. Le modèle utilisé est un modèle statique basé sur la MCS (2007). Les principaux résultats: une perte probable au niveau PIB réel d’un montant de 3 milliards de dirhams, la consommation privée et publique, respectivement, de plus de 2,5 milliards de dirhams et 1,3 milliards de dirhams. Quant aux agrégats ayant bénéficié d’une hausse, sont la production locale et la consommation intermédiaire, fort, d’environ un milliard de dirhams. Mots clés: CGER, MEGC, MCS, Bouclage, Analyse de sensibilité. Abstract The aimof this thesis is to analyze the impact of equilibrium real exchange rate’s misalignments on the macroeconomic balance. To achieve this objective, we opted forthe CGER method developed by IMF’s experts. In 2006, according to the results of our study, the annual evolution of the misalignments following geometric average, during 2006-2011, is around 2.5 %. Thus, misalignment’s studies in MEGC has been recognized as the best, to assess the misalignment’s effects on the macroeconomic stability. The model, adapted to the national economy, used in this study is a static model based on the MCS (2007). The main macroeconomics results of the misalignment’s impact are: A probable loss on real GDP around 3 billion dirhams, private and public consumption, respectively, around 2.5 billion and 1.3 billion dirhams. Though, the aggregates having benefited from a rise, are the local production and the intermediate consumption. Keywords: CGER, CGE, MCS, Looping, Sensitivity Analysis.

description: Many peri-urban bodies of water are irreversibly damaged by eutrophication around the world. This study was carried out to know the spatial and temporal dynamics of nitrogen and phosphorus compounds contained in Gagnoa’s water reservoir and in its tributaries. During the long rainy and dry seasons from 2005, 2011 to 2013, nineteen sites’ waters, from springs, rivers and the reservoir permitted to analyze nutrients with the colorimetric method using a spectrophometer 2400/HACH LANGE. The values of nitrogen compounds showed a significant difference (p ˂ 0.05) during spatiotemporal variation. The water reservoir deemed to be at mesotrophic to eutrophic stage is more enriched with nutrients in the rainy season with a decrease in transparence and in chlorophyll a. This is explained by the use of fertilizers on the studied watershed, wastewater discharges, laundry doing and animals dejecta. These findings could be used as the basis for the setting-up of an integrated management plan for the water reservoir and its watershed.

description: Résumé L’endettement est assurément une source fondamentale, voire inévitable de financement. Il est souvent considéré comme une opportunité mais en même temps, peut constituer un véritable fardeau pour les entités qui y recourent. En effet, l’endettement représente un élément moteur de la croissance. Il a pour mission de soutenir le développement et l’amélioration des performances. Il permet également d’accompagner les opérations de l’entreprise en finançant les besoins courants ou urgents nés de l’exploitation. Cependant le recours à l’endettement n’est pas gratuit. Il est générateur de coût et de difficultés en entraînant le paiement de charges financières parfois lourdes. Il est soumis à un échéancier de remboursement inflexible. Les contraintes de l’endettement peuvent atteindre des niveaux tels que l’entreprise ne soit plus en mesured’honorer ses engagements à l’égard des créanciers et des bailleurs de fonds. Le présent travail vise à appréhender la portée etl’enjeu de l’endettement. Ilcherche essentiellement, à partir d’une étude empirique auprès des entreprises marocaines, à vérifier la relation qui lie le coût de l’endettement à la rentabilité financière de la firme.

description: In Niger, the prevalence of moderate acute malnutrition in children aged 6-59 months varies between 10-15%. Community participation is essential in monitoring the nutritional status of children less than five years of age. The objective of this study was to assess parents' knowledge regarding moderate acute malnutrition and the parameters of its management, 12 years after the major food crisis of 2005. The method used consisted firstly of a quantitative approach using a questionnaire administered to 300 individuals who directly or indirectly participates in children nutritional status management including a self-administered questionnaire to 10 health workers and a non-participatory observation qualitative approach Of care in health centers. We observed that only 1% of respondents had good knowledge of moderate acute malnutrition. We however found that 20% of respondents exhibited a good knowledge of the direct causes of malnutrition and its consequences. We also observed a good that 35% of the respondents were aware of the most affected age group. In addition, the study showed knowledge of a good nutrition practice in 74.4% and a good knowledge of the means of preventing malnutrition in 67.7%. More than 95% of the respondents were aware of the place of call for care in case of malnutrition, the means of detection and the importance of the vaccination. Indeed, the knowledge of the parameters of the management of the malnourished children was adequate and complies with the guidelines of the National Protocol in 70% of the health agents surveyed. Nevertheless, knowledge about malnutrition in children needs to be improved and the capacity of health workers to be strengthened on this scourge for better care for malnourished children.

description: BackgroundDuring the height of the COVID-19 pandemic, a crucial and dynamic response was orchestrated by Qatar’s government. To effectively manage the escalating cases, a general hospital was transformed into a dedicated COVID-19 facility. This transformation was testament to the power of interdisciplinary collaboration and meticulous adherence to international guidelines, primarily those set forth by the World Health Organization (WHO) and the Centers for Disease Control and Prevention (CDC).MethodsThe transformation involved deploying thermal scanners, activating the System-Wide Incident Command Centre (SWICC), optimizing quarantine facilities, managing Personal Protective Equipment supply, and introducing advanced disinfection technologies, overseen by engineers ensuring secure infrastructure modifications.ResultsThe transformed hospital became a fully operational COVID-19 treatment center, aided by the distribution of 500 portable high efficiency particulate air (HEPA) filters, establishment of seven field hospitals, and commissioning of two large swabbing centres. Within the facility, notable additions included 211 bed units with oxygen inlets, 21 dialysis water inlets and drains, over 200 acrylic screen protectors, and the setup of five swabbing stations and intubation boxes. Collaboration with the Qatar Scientific Club led to the introduction of two Ultraviolet light disinfection machines. Additionally, 20 Powered Air Purifying Respirators significantly enhanced healthcare workers' safety.ConclusionThe comprehensive strategy, and strict infection prevention measures, significantly improved patient care and healthcare workers’ safety during the COVID-19 response. These initiatives, such as portable HEPA filters and infrastructure enhancements, strengthened the healthcare system's response to rising cases and serve as a scalable model for global health crisis management. According to WHO guidance2, these collective efforts and adherence to protocols are crucial in minimizing transmission risks in medical facilities, underlining the importance of proactive strategies and interdisciplinary collaboration in managing healthcare crises for global public health.

description: Water hyacinth originating from South America was introduced into several regions of the world as an ornamental plant. Its biological characteristics, including capacities of sexual and asexual reproduction ways very effective, its high growth rate and productivity, allowed it to colonize freshwater communities and be very competitive to other plant species. E crassipes shows the most significant growth rate in comparison with other terrestrial or aquatical species. Because of its ecological and socio-economic impacts, it belongs to the "100 most harmful invasive species in the world”. Several methods of fight such as physical, chemical and biological are adopted to eradicate this invasive plant. Given the limitations of use of these different methods, the development of an effective short-term control technique without major environmental impact would be an adequate solution to combat its expansion.

Il vise à étudier l’influence des dimensions de la qualité (qualité du système, de l’information et du service) sur le succès de la technologie web universitaire. Ce succès se mesure par la satisfaction des utilisateurs et les bénéfices organisationnels. Une étude quantitative a été menée dans la faculté de droit d’Agadir dans le but de valider les hypothèses issues de ce modèle de recherche. Les résultats montrent une corrélation significative et positive entre les trois dimensions de la qualité et le succès de la technologie web. Ils montrent également l’importance des dimensions de la qualité pour la maitrise du coût et du délai de la diffusion et de la recherche de l’information. Mots clés : Technologie Web, système d’information, Facteurs de succès, qualité de la technologie web Abstract This paper proposes a model to test the web technology success in an academic context based on the updated Delone and McLean (2003) original success model. It aims to study the influence of the quality dimensions (system quality, information quality and service quality) on the web technology success. This success is measured by user satisfaction and organizational benefits. A quantitative study was conducted in the faculty of law in Agadir to validate the hypotheses derived from the research model. The results show a significant and positive relationship between the three dimensions of quality and web technology success.

Subjects: Adsorption, Kinetics, Dye, activated carbon.

description: Worldwide industrial and technological advances have introduced various pollutants into the water. Pollutants can be organic contaminants and heavy metals. This presence in industrial effluents where drinking water is a public health problem due to their absorption and, subsequently, their accumulation in the human body. Water pollution regulations require textile industries to reduce considerably the amount of dyes in their releases. Adsorption, a sewage treatment process, exploits the capacity of a few solids to concentrate certain substances on their surfaces. Generally, the adsorbent most used for the treatment of textile effluents is activated carbon. In this work, we studied the kinetics of adsorption of an acid dye, red in aqueous solution, tivated carbon based of natural materials (date nuts, wood and natural charcoal) in a batch process. The initial concentration of the dye was 60 mg.L-1 determined by a spectrophotometric method. The influence of certain parameters, such as pH, mass of activated carbon in solution, initial dye concentration and contact time was studied. The results showed an increase with contact time and mass of active carbon, and a decrease with pH.

Year: 2017
Subjects: Heavy metals, seawater, sediments, seasonal variations.

description: Seawater and sediment samples were collected from five locations (Burum, Al-Mukalla, Al-Shaher, Ras-Sharma and Arryidah) in coastal of Hadraomut, Yemen on seasonally basis from August 2013- May 2014 for an investigation of concentrations of heavy metals [nickel (Ni), cobalt (Co), manganese (Mn),cadmium (Cd), iron (Fe), copper (Cu), zinc (Zn), chromium (Cr) and lead (Pb)]. The higher concentration of Ni, Co, Mn, Cd, Fe, Cu, Zn and Pb in seawater and sediments were observed in Al-Mukalla site, which was considered a contaminated area. These concentrations exceed largely those in Ras-Sharma site (protected area) The present study showed that there were no significant differences at (P≥0.05) in the concentrations of heavy metals in the all locations in seawater except for Mn, Cd and Zn which is a were significant differences at (P≤0.05) the all locations .while results of sediments showed were significant differences at (P≤0.05) in the concentrations of heavy metals between the all locations except for Ni, Co, Mn and Fe which is not a were significant differences at (P≥0.05) in all locations. In the opposite heavy metals of sediment collected from different locations showed significant differences at (P≤0.05) except for Ni,Co, Mn and Fe for which no concentrations of heavy metals in water and sediments samples collected from Al-Mukalla site exceeded the maximum limits proposed by EPA (2001) and the National Oceanic and Atmospheric Administration ( NOAA,2009). Therefore, Al-Mukalla site is a very contaminated are compared to ( Ras-Sharma site) this might be related to the different activities of Al-Mukalla harbor, electrical power station, wastewater from fish industry, Hadhramout hotel and discharge of untreated sewage.

description: BackgroundPlayers are often viewed as the single-most important participants in a FIFA World CupTM, but in fact spectators make it a global spectacle. Qatar received 1.4 million visitors during the FIFA World Cup 2022TM, a 50% increase in population. The aim was to provide high quality medical care to the visiting spectators, while continuing regular medical services for residents. This presentation overviews the challenges and solutions when hosting the world’s largest sporting event.MethodsThis is a case study of the planning and provision of spectator healthcare services during the FIFA World Cup 2022TM. ResultsThere were additional clinics setup for the tournament, majority located in the stadiums for match days (85 clinics) and 30 clinics at other sites, including official hotels and fan villages. Each clinic was staffed by a physician and nurse while paramedic teams ensured prompt assessment and management of first aid and emergency situations in the stadiums and fan areas. Stadium teams were deployed to cover two stadiums according to tournament schedules. In addition, a central workforce hub was setup to provide central coordination of all workforce related issues, including rostering, training, transport and accreditation issues. An important component of smooth clinic functioning included a standardised inventory for all tournament clinics, which were proactively restocked with medical supplies using an electronic management system supported by a central logistics hub. ConclusionThe provision of healthcare services throughout the FIFA World CupTM was undertaken to a very high standard, acknowledged by the various stakeholders involved. The central theme was teamwork and coordination between the involved stakeholder organisations along with their representative deployed staff. The arrangement to utilise one medical team to cover two stadiums was a core factor in being able to successfully prepare and execute the delivery of high-quality healthcare for visitor and residents alike
Evaluation of the impact of anthropogenic actions on the Nador lagoon (Morocco) by the index of the sediment pollution load
Creators: name: SADDIK, Mohammed

Year: 2017
Subjects: Nador lagoon, sediments, contamination, heavy metals, pollution.

description: In order to assess the degree of chemical contamination of the Nador Lagoon (NE Morocco), superficial sediment samples (0-10 cm) were collected at 28 points of the lagoon and the total heavy metal contents (Cu, Cd, Cr, Ni, Pb and Zn) were determined. The spatial distribution of the pollutant load index (PLI) in the lagoon shows that the Merchica lagoon has a moderate degree of contamination (contaminated to moderately contaminated) except in areas close to Selouane, El Mrader, and El Bachir rivers, and the town of Beni Ensar where there is a severe contamination. This can be explained on the one hand by urban liquid discharges and the liquid discharges conveyed by these rivers and on the other hand by hydrocarbon discharges and the activities of the boats in the Beni Ensar area.
