This document describes the creation of an informative Web GIS aimed at mitigating the impacts of flooding in the municipality of Ouagadougou, in Burkina Faso, a region that is highly sensitive to climate change. Burkina Faso, which is undergoing rapid urbanization, faces major natural threats, particularly flooding, as demonstrated by the severe floods of 2009 that caused loss of life, injury, structural damage and economic losses in Ouagadougou. The aim of this research is to develop a web map highlighting the municipality’s flood-prone areas, with a view to informing and raising awareness of flood risk reduction. Using the Leaflet JavaScript mapping library, the study uses HTML, CSS and JavaScript to implement web mapping technology. Data on Ouagadougou’s flood zones is generated by a multi-criteria analysis combining Saaty’s AHP method and GIS in QGIS, integrating seven (7) parameters including hydrography, altitude, slope, rainfall, soil types, land use and soil moisture index. QGIS processes and maps the themes, PostgreSQL with PostGIS serves as the DBMS and GeoServer functions as the map server. The Web GIS platform allows users to visualize the different flood risks, from very low to very high, or the high-risk areas specific to Ouagadougou. The AHP calculations classify the municipality into five flood vulnerability zones: very low (24.48%), low (27.93%), medium (23.01%), high (17.11%) and very high (7.47%). Effective risk management requires communication and awareness-raising. This online mapping application serves as a tool for communication, management and flood prevention in Ouagadougou, helping to mitigate flood-related natural disasters.

Effect of Different Mulching Materials on Growth Parameters and Yield of Okra (Abelmoschus esculentus) Production in Minna, Nigeria

引用

Open Journal of Forestry 2024年第3期14卷 197-213页

作者： Ebierin Akpoebidimiyen Otuaro John Jiya Musa Mohammed Musa Isah Abayomi ibrahim Kuti Muhammad Yusuf Salihu Department of Civil Engineering Faculty of Engineering Maritime University Okerenkoko Nigeria Department of Agriculture and Bioresources Engineering Federal University of Technology Minna Nigeria

During the 2022 growing season (August to November) at the Federal University of Technology, Minna School farm, Niger State, an experiment was conducted to investigate the influence of mulching on Okras growth, yield, and moisture content was examined across four distinct growth stages (initial, development, mid, and late) and at varying soil depths (0 - 30 cm and 30 - 60 cm). The study employed a randomised complete block design with four replications, encompassing control (T0), groundnut shells mulch (T1), black polythene mulch (T2), and white polythene mulch (T3) as treatments. The highest average Okra fresh pod yield, amounting to 23.4 t/ha, was achieved by implementing white plastic mulch, contrasting with the control treatment, which yielded the lowest at 22 t/ha. Notably, the control plots exhibited yield reductions of up to 32% compared to the plots employing white plastic mulching. The utilisation of mulch had a notable impact on the overall crop yield, with the superior quality evident in the treatment employing white plastic mulch (26 t/ha). The control treatment exhibited the lowest quality at 24.3 t/ha. Groundnut shell mulch influenced moisture conservation, but no significant variance was observed compared to the control plots. Therefore, the study suggests that polythene mulch may be the most suitable type to enhance the quality of okra production by conserving soil moisture. Among the biodegradable and non-biodegradable mulches used in this study, white polythene mulch was the most effective.

Open Journal of Soil Science 2024年第4期14卷 191-209页

作者： Frank Abigail Sobze Kenfack Georges Kogge Kome Achille Bienvenue ibrahim Viviane Pauline Mandah Dieudonne Bitondo Department of Soil Science Faculty of Agronomy and Agricultural Sciences (FASA) University of Dschang Dschang Cameroon Department of Land Surveying National Advanced School of Public Works Yaound&#233 Cameroon International Institute of Tropical Agriculture Cameroon Eco-Regional Center HFS Yaound&#233 Cameroon Department of Earth Science Faculty of Science University of Dschang Dschang Cameroon

This study was conducted to assess the current stock of soil organic carbon under different agricultural land uses, soil types and soil depths in the Noun plain in western Cameroon. Three sites were selected for the study, namely Mangoum, Makeka and Fossang, representative of the three dominant soil types of the noun plain (Andosols, Acrisols and Ferralsols). Three land uses were selected per site including natural vegetation, agroforest and crop field. Soil was sampled at three depths;0 - 20 cm, 20 - 40 cm, and 40 - 60 cm. Analysis of variance showed that soil type did not significantly influence carbon storage, but rather land uses and soil depth. SOCS decreased significantly with depth in all the sites, with an average stock of 66.3 ± 15.8 tC/ha at 0 - 20 cm, compared to an average stock of 33.3 ± 7.4 tC/ha at 40 - 60 cm. SOCS was significantly highest in the natural formation with 57.2 ± 19.7 tC/ha, and lowest in cultivated fields, at 37.7 ± 10.6 tC/ha. Andosols, with their high content of coarse fragments, stored less organic carbon than Ferralsols and Acrisols.

Introduction: Infections are significant causes of mortality in sickle cell children in resource-limited countries. This study aimed to determine the clinical profile and bacterial ecology of infections in children with sickle-cell disease in two referral hospitals in Niamey. Patients and methods: A retrospective descriptive study was conducted from January 2018 to July 2020 in two referral hospitals in Niamey. All children aged one (1) to 15 years with sickle cell disease admitted for suspected infection, including at least one bacterial culture, were studied. Bacteriological analysis was performed using the appropriate culture media, using BactAlert (Reference 4700003 BTA3D60 BioMérieux). Results: Over 36-months, 350 children with a mean age of 10.9 months were admitted. The sex ratio was 1.2. The SS electrophoretic profile was the most common (93.4%). Immunization status was up to date in 66% of patients. Fever was the common reason for consultation (55.1%). Infection was confirmed in 62 patients (17.7%). The primary diagnoses were bacterial gastroenteritis (24.2%) and urinary tract infection (19.4%). Blood cultures were isolated from Salmonella typhi (13.0%) and Escherichia coli (8.7%). Klebsiella spp (7.1%) and Escherichia coli (5.0%) were detected in cytobacteriological examination of urine. Salmonella typhi (23.5%) and Escherichia coli (5.9%) were isolated on coproculture. Conclusion: Bacterial ecology appears not different from that usually observed in sickle-cell children. Salmonella and Escherichia coli were predominant.

Background: The choice of the appropriate operative intervention in patients with late and neglected hip fracture continuous to be a huge dilemma for orthopedic surgeons. Purpose: To evaluate the satisfaction or otherwise of some treatment options using the modified Harris-hip score (HHS) in resource poor setting. Materials and Methods: A retrospective cross-sectional study conducted at ATBUTH, Bauchi. Data of 60 patients over the age of 18 years with hip fractures (femoral neck, intertrochanteric and sub trochanteric fractures) who had operative intervention between 1st September 2019 and 31st August 2020 with cannulated screws, Proximal femur lock compression plate (PFLCP), cementlessor cemented bipolar hemiarthroplasty (BHA). Results: The mean age of studied patients was 65.7 ± 16.1 years, with age ranging from 19 - 101 years. M:F ratio was 1.2:1 across all age groups and 1:1.4 amongst those >60 years. 51 patients (85%) presented > 1 week after injury with 24 patients (40%) sustaining hip fractures from low energy trivial indoor fall and 28 patients (46.7%) mostly younger sustaining fractures from high energy motor vehicular accident (MVA). The prevalence rate for femoral neck, intertrochanteric and subtrochanteric fractures were 32 (53.3%), 17 (28.3%) and 11 (18.3%) respectively. From the data retrieved, 21patients (35.0%), 17 patients (28.3%), 20 patients (33.3%) and 2 patients (3.3%) had PFLCP, cemented BHA, cementless BHA and cannulated screw fixation respectively. Most (66.7%) of those who had PFLCP achieved satisfactory radiologic union and there was also 94.1% and 85% satisfactory outcome rate amongst the patients with cemented BHA and cementless BHA respectively. Irrespective of the operative intervention method at 1 year follow-up, there was a statistically significant improvement in post-operative HHS (P value 0.02), with 83.4% having good to excellent results.

Preliminary Study of Chemical Elements Distribution in Petroleum Source Rocks Donga and Yogou Formations of the Termit Sedimentary Basin (Est-Niger)

引用

Journal of Minerals and Materials Characterization and Engineering 2024年第1期12卷 49-62页

作者： Alassane ibrahim Maman Bachir Abdoulaye Dan Makaou Oumarou Baraou Idi Souley Kouakou Alponse Yaou Abdoulwahid Sani Department of Fossil Energy University of Agadez (UAZ) Agadez Niger Civil Engineering Geosciences and Geographic Sciences Laboratory Institut National Polytechnique Félix Houphou&#235t Boigny (INP-HB) Yamoussoukro C&#244te d’Ivoire Department of Geology University of Agadez (UAZ) Agadez Niger

XRF and EDX analyses were carried out on 18 batches of representative raw samples to determine the distribution of major chemical elements in the petroleum source rocks of Donga and Yogou formations of Termit sedimentary basin. The chemical composition of these formations is dominated by silicon (Si), aluminum (Al) and iron (Fe). This is consistent with the oxide composition, which is also dominated by silicon oxide (SiO2), aluminum oxide (Al2O3) and iron monoxide (FeO). No less important chemical elements are calcium (Ca), potassium (K), sulfur (S), titanium (Ti), magnesium (Mg), manganese (Mn) and barium (Ba), as well as some of their oxides. All these major chemical elements are carried by silicate detrital minerals associated with pyrite and goethite and/or clay minerals such as kaolinite and interstratified illite, smectite and chlorite. This trend is illustrated by the values of the Si/Al and SiO2/Al2O3 ratios.

Study of the Constraints of Millet Production (Pennisetum glaucum (L.) R. Br.) and the Peasant Perception of Biological Control in the Tahoua Region

引用

Agricultural Sciences 2024年第1期15卷 1-14页

作者： Rabé Mahamane Moctar Hama Oumarou Issaka Rabo Salissou Abdoulaye Amoustapha Soumaila Bakoye Nouhou Ousmane Baoua ibrahim Faculty of Agricultural Sciences Djibo Hamani University of Tahoua Tahoua Niger NGO Sahel Bio of Maradi Maradi Niger Faculty of Agronomy and Environnemental Science DanDicko DanKoulodo University of Maradi Maradi Niger

Millet (Pennisetum glaucum (L.) R. Br.) is the Sahelian crop par excellence due to its adaptation to the particular production conditions in this region. Unfortunately, in recent years this crop has been threatened by very strong parasitic pressure and drought during the production period. The objective of this study is to analyze the main constraints of millet production and the solutions known to producers. A survey was carried out in November 2022 with a sample of 298 producers in five municipalities in the Tahoua region. The main constraints are drought and pressure from crop pests (locust, millet ear miner, floricultural insects) according to 57.9% of respondents. The millet ear miner is the most formidable pest according to 55% of respondents. Thus, the average yield obtained in a year of good production without the leafminer is 194 kg/ha and that obtained in a year of millet ear leafminer is around 27 kg to 43 kg/ha depending on the municipality. The yield obtained this last campaign after the attack of this leafminer varies from 64 to 77 kg/ha depending on the municipalities compared to a potential yield of over 1000 kg/ha. More than half of producers (58.1%) are unaware of the existence of biological control compared to only 12.5% who are aware of this alternative method. Work to popularize this technology is necessary in the five municipalities and the entire region in general.

Exoscopy of Detrital Zircons from Niamey Neoproterozoic Sandstones (Eastern Edge of the West African Craton, Southwestern Niger): Interpretation of Detrital Sediments Provenance

引用

Open Journal of Geology 2024年第5期14卷 617-628页

作者： Hassan ibrahim Maharou Karimou Laouali Idi Diafarou Alzouma Amadou Salissou Abdoul Ganiou Amadou Gnissa Sidibé Moussa Konaté Department of Geology Faculty of Science and Techniques Abdou Moumouni University Niamey Niger Department of Life and Earth Sciences Ecole Normale Sup&#233rieure (ENS) Abdou Moumouni University Niamey Niger

This study focuses on exoscopic analyses of detrital zircon grains of Archean and Paleoproterozoic age, contained in the sediments from the Niamey Neoproterozoic sandstones (Niamey region), with a view to confirming the sediments sources already proposed (Kénéma-Man domain for Archean-age zircons and Baoulé Mossi domain for Paleoproterozoic-age zircons). Exoscopic analysis reveals that Archean zircon grains are more corroded, with rounded to sub-rounded shapes, while Paleoproterozoic zircon grains are less corroded and mostly angular in shape. The strong corrosion of Archean zircon grains, implying long-distance transport, is consistent with the remoteness of the Kenema-Man domain which are the source these sediments. The fact that the Paleoproterozoic zircon grains show little or no wear implies a proximal source of sediments, corresponding to the Baoulé Mossi domain.

Open Journal of Urology 2024年第7期14卷 407-414页

作者： Makama Baje Salihu Haruna Liman Stephen Yusuf Aminu Umar Oladimeji Abraham Tunde Ayodele Olufikayo Oshagbemi Amur ibrahim Urology Unit Department of Surgery Abubakar Tafawa Balewa University Teaching Hospital Bauchi Nigeria

Background: Fournier’s gangrene is a fulminant infection of the genitourinary tract characterized by progressive necrosis of the skin and subcutaneous tissue of the external genitalia. Initially mainly seen involving the scrotum of elderly men with different moods of occurrence each unpleasantly lethal. With varying types of presentation only one thing has remained constant;the poor prognosis of this condition. Purpose/Aim: Thus, it’s important to study the trends of the presentation of this condition laying emphasis on the challenges in the management of these patients;both the negative and positive prognostic factors. Materials and Methods: Urology ward record books, clinic record books and operating theater records were used to identify patients managed for Fournier gangrene in ATBUTH Bauchi. A retrospective study of the medical files of all the patients managed from January 2011 to January 2024 was done. Data was analyzed using SPSS version 29. Results: Data from 47 patients seen during the period of study were carefully collected and analyzed. The age range is 2 weeks to 97 years. There were two neonates, one at 2nd week of life and the other at 3rd week. Mortality rate is 36%. The average time duration before presentation for patients that died was two weeks, a minimum of 9 days prior to presentation and a maximum of 21 days, about 10 of which came in septic shock and the remaining presented with fever and very extensive necrotizing fasciitis of the perineum. All the patients that died had diabetes mellitus as a comorbidity except the neonate. All the patients that survived were much younger, all were below 60 years of age (2 weeks - 53 years). Conclusion: Here, we share our experience managing patients with Fournier’s gangrene in our facility in the past 13-year period from January 2011 to January 2024. .
