Authors: Nisreen Jawad Kadhim  
Published: July 2024

Background: Streptococcus pyogenes is a common cause of bacterial pharyngitis in children. Although distinguishing between viral and bacterial pharyngitis solely on the basis of signs and symptoms can be difficult, culture-based diagnosis and study characteristics are crucial to avert potentially fatal outcomes. Therefore, the purpose of this investigation was to ascertain the occurrence of S. pyogenes using a culture approach that followed a biochemical test and a PCR experiment that targeted the 16S rRNA, sepl, and spek genes. By logging and evaluating the results, the PCR assay's sensitivity, specificity, positive, and negative predictive values were established in relation to the culture method. Methods: Between 2022 and 2023, a total of 170 throat swabs were taken from pharyngitis patients who were referred to Fallujah General Teaching Hospital and AL Hussein Teaching Hospital for children in Iraq ages 2 to 10.The identification of S. pyogenes using biochemical testing, 16S rRNA, and multiplex polymerase chain reaction (multiplex PCR) for the detection of virulence factor genes (SpeL and SpeK genes). Results: This study included a total of 170 children with acute pharyngitis. Of these, 75 (44.11%) were culture optimistic for S. pyogenes, a biochemical test and 16SrRNA based on the Multiplex PCR examination presented, sepl 9 (12%)and spek 6 (8%) genes were noticed in 10.51% and 8.55%, respectively, of the isolates. Conclusion: The study aimed to identify risk factors for S. pyogenes infection among children in a large clinical trial in Iraq.

Why Amphistegina lobifera, a tropical benthic foraminiferal species, is thriving at temperate latitudes in the Mediterranean Sea
Authors: Hallock Pamela , Koukousioura Olga , BadrElDin Ahmed Mohamed 
Published: July 2024

Abstract
Amphistegina lobifera Larsen is a relatively large (adult diameter ∼1–3 mm), robust, diatom-symbiont-bearing benthic foraminiferal species that thrives in clear, nutrient-poor coastal waters throughout much of the subtropical/tropical Indo-Pacific. Studies in the late 19th to mid-20th century noted the predominance of the shells of Amphistegina and Calcarina in Holocene reef sediments, enhanced by hydrodynamic sorting and by the resistance of these shells to abrasion. Having migrated through the Suez Canal at least 60–80 years before present, A. lobifera populations have proliferated in the eastern Mediterranean Sea and have expanded their range westward. As Mediterranean waters warm, these foraminifers are thriving in oligotrophic, shallow-water habitats, and have produced shell accumulations of a half meter or more in some areas. While the success of A. lobifera has raised concerns about its proliferation as an invasive species, assessments of foraminiferal assemblages along nutrient gradients have shown dominance only distant from nutrient sources, whether natural or anthropogenic. The genus Amphistegina emerged in the Eocene under higher atmospheric CO2 concentrations than present and experimental studies have shown that these foraminifers can sustain shell-growth rates under elevated pCO2. Warming temperatures also increase metabolic rates, increasing the energetic advantages of algal symbiosis. As surface waters continue to warm, the already elevated salinity and alkalinity in the eastern and central Mediterranean should further enhance carbonate production by A. lobifera and possibly by other benthic foraminifers that host algal symbionts. Observed rates of accumulation by hydrodynamic concentration of dead shells by nearshore wave action are comparable to rates of ongoing sea-level rise. Might this return of prolific shallow-water carbonate production ultimately prove at least locally beneficial as climate change progresses?

Published: July 2024

The study began with a reconnaissance survey that used high-resolution aeromagnetic data of the study area to identify suitable structure zones with the potential to trap mineral resources within the context of the gold exploration target. The findings of magnetic studies were followed up with detailed investigations using 2D electrical resistivity tomography (ERT) and induced polorisation (IP) techniques to reveal further details about gold mineral zones and other lithological boundaries. The airborne magnetic data of sheet 118_Yelwa was obtained from the NGSA; these datasets were processed and analyzed using Oasis Montaj's first vertical derivative (FVD) and center for exploration targeting (CET) techniques. Results of FVD and CET grid anomalies show that regions of major magnetic structures (lineaments) are associated with granite gneiss, migmatitic augen gneiss, and medium to coarse-grained biotite when compared to the geological settings of the area. The zones of major structures obtained in this study coincided with previous magnetic studies of the area, located in the eastern parts of Ngaski, Yauri (Yelwa), Shanga, Agwara, as well as Magama's northwest region. Some of the regions for lineament (in the eastern part of Ngaski/Yauri) were investigated further with 2D ERT and IP detailed geophysical methods in a dipole-dipole configuration. The results of geoelectric techniques along profiles 1, 2, and 3 identified the major gold mineralisation potential zones, which were labeled A1, A2, and A3. These regions have low/high resistivity (1.6 to 459 Ωm/1889 to 7773 Ωm) and chargeability signatures (≥ 20 msec), and could thus be interpreted as potential target zones for metallic mineral exploration, particularly gold mineralisation. The regions are located in the northern Mararraba and southwest of the Jinsani areas of Kebbi State. The results of integrated geophysical methods have produced updated structural features of the regions, as well as a database containing precise locations, lateral lengths,...

Path loss assessment is an important factor in wireless communications to ensure quality of service. This study involves the measurement of Received Signal Strength (RSS) of Digital Terrestrial Television (DTTV) Star Times Station in Kano at 1 km intervals along three routes. Data were gathered during dry and wet season months in the year 2022. The path loss along the routes were computed based on the Okumura-Hata model. It was observed that path losses were higher during wet than dry season months. The result also indicates a higher negative correlation coefficient (R) of -0.745 between Line of Sight (LOS) and RSS for wet and -0.690 for dry season months respectively for route, A. Similarly, R, of -0.739 between LOS and RSS was also observed during wet and -0.589 for dry season months for route, B. In addition, R, of -0.420 was observed between LOS and RSS during wet and -0.328 for dry season months along route C. The average path loss for wet season is 133.90 dB and for dry season is 127.90 dB. Furthermore, this study introduced a Modified Hata Path Loss Model (MHPL) that takes into account the impact of specific tropospheric parameters such as LOS and elevation. Findings further indicated that the path loss predicted by the conventional Hata model exhibited a steady exponential increase with LOS. Similarly, MHPL followed a comparable trajectory, with some exceptions manifesting as peaks and valleys. The overall findings will be useful for power budgeting that will enhance quality of service of DTTV signal over Kano city.

Delineation of the groundwater potential zones in the Cretaceous Lower Benue and Niger Delta basins of Abia state, Nigeria with geographic information system (GIS) / remote sensing (RS) multi-criteria decision approach (MCDA) considered the significant hydrogeomorphological factors affecting the availability of groundwater resources. The factors (geology, rainfall, slope, drainage density, lineament density, soil type, and land use land cover) were ranked using the analytical hierarchical process, a multi-criteria decision-making tool. The integration of the factors into a geographic information system (GIS) and weighted overlay analysis were then carried out using ArcGIS software. The result indicates 31.5% of zones of high to very high groundwater occurrence are in the southern section, and 41.6% of poor to very poor zones in the northern section. While the moderate zones make up the 26.8% of the study area. The study demonstrates that the groundwater occurrence in the study area is primarily controlled by the interactive impact of geology, rainfall, and slope factors, thus revealing the causes of the incessant random borehole failures in the moderate zones. Thus, the groundwater resources can be sustainably exploited, developed, and managed with the help of the map produced from the resulting demarcation of groundwater potential zones in the study.

Dans la présente contribution, nous tentons à travers une expérimentation de mettre en évidence la pertinence de l’usage des réseaux sociaux, en l’occurrence Facebook dans l’appropriation du savoir-écrire en langue française. Notre enquête a été effectuée à la base d’un questionnaire adressé à des étudiants normaliens de langue française de la Wilaya de Mostaganem. L’enquête de terrain a révélé que ces étudiants éprouvent une grande volonté, voire un grand intérêt pour l’écriture numérique notamment sur le réseau social Facebook, d’autant plus qu’ils arrivent à dépasser le sentiment d’insécurité linguistique ressenti en classe et ce grâce à l’interaction sociale avec des interlocuteurs plus compétents et aux fonctions qu’offre l’outil informatique dans le processus de la rédaction en mode numérique. Ils se sentent libres, actifs, productifs et commettent moins d’erreurs
Abstract
In this contribution, we attempt through an experiment to highlight the relevance of the use of social networks, in this case Facebook, in the appropriation of knowledge of writing in the French language. Our survey was carried out on the basis of a questionnaire addressed to French-speaking normaliens students from the Wilaya of Mostaganem. The field investigation revealed that these students have a great desire, even a great interest, in digital writing, particularly on the social network Facebook, especially since they manage to overcome the feeling of linguistic insecurity felt in class. And this thanks to social interaction with more competent interlocutors and to the functions offered by the computer tool in the digital writing process. They feel free, active, productive and make fewer mistakes.
