Introduction: Headaches are a common symptom affecting individuals worldwide, including in the tropical zone, and have been extensively studied in Togo. Phosphodiesterase-5 inhibitors, commonly prescribed for erectile dysfunction, are k.own to induce headaches, yet there is a lack.of research on this topic in sub-Saharan Africa and Togo. Methods: A cross-sectional study conducted from February 1st to June 30th, 2023, including adult patients seek.ng erectile dysfunction treatment and prescribed PDE-5 inhibitors. Results: A total of 28 patients were included in the study, with an average age of 34.46 ± 7.5 years. The age group of 30 - 39 years was the most represented (53.57%). Among the participants, 67.86% had a history of chronic headaches. During the intak. of PDE-5 inhibitors, 71.43% reported the onset of headaches. Among the 19 patients with chronic headaches, 68.42% developed headaches following PDE-5 inhibitor use (RR = 0.88, 95% CI: 0.55 - 1.40, p = 0.484). The characteristics of the induced headaches were similar to the patients’ pre-existing headaches in 78.95% of cases. Additional symptoms included nasal congestion (36.84%) and an urge to have a bowel movement (26.32%). Sildenafil (75.00%) and Tadalafil (25.00%) were the primarily prescribed PDE-5 inhibitors. The incidence of headaches did not significantly differ between the two groups (RR = 1.33, 95% CI: 0.67 - 2.64, p = 0.306). Treatment for the induced headaches involved self-medication with paracetamol (65.00%) and nonsteroidal anti-inflammatory drugs (NSAIDs) (35.00%). Conclusion: Headaches induced by PDE-5 inhibitors are a well-established reality, emphasizing the need for caution and warning in patients with pre-existing headache conditions, while individualized approaches are necessary to address the potential interplay between migraine medications and erectile dysfunction treatments.

Petrology and Geochemical Relationship of Birimian Gabbro-Diorite-Granodiorite Dyk.s in Basaltic Rock. at Butre Area, SW Ghana

引用

Journal of Geoscience and Environment Protection 2024年第2期12卷 107-130页

作者： Victor Graham George mensah Tetteh Department of Geological Engineering University of Mines and Technology Tarkwa Ghana

Granitoids at Butre area, south-western part of the Birimian of Ghana are gabbro to granodiorite which intruded comagmatic basalt and andesite of volcanic island arc setting. Differentiation was from probably mantle fractionates on tholeiitic basalt trend through gabbro-diorite and granodiorite. Yet, the diorite intruded into the volcanic rock. prior to plate collision. Plagioclase feldspars of labradorite to andesine compositions (An52 - An48), amphibole and pyroxene are in association with accessory tourmaline, actinolite, apatite and garnet. Relict amphibolite facies metamorphism is preserved in xenoliths in gabbro to diorite which show greenschist facies. Generally, plagioclase is partially altered to fine quartz, sericite and carbonates whereas chlorite and epidote are of amphibole alteration. These alterations are typical of carbonatisation but diorite shows partial carbonate-sericite alteration. Alterations followed granodiorite emplacement. Arsenopyrite and pyrite accompanied emplacement of diorite and granodiorite respectively while amphibolite facies metamorphism introduced magnetite;haematite and pyrrhotite accompanied greenschist facies metamorphism. Earlier opaque minerals possibly were consumed to form later minerals. All the rock. are LREE depleted (La/Sm chondrite normalised ratios of basalt = 0.8 to 2.5;andesite = 2.03;diorite = 1.95 to 3.1;gabbro-diorite = 0.9 to 2.05;granodiorite = 1.66);diorite, basalt and andesite are fairly enriched in HREE. Enrichment of FeOT, MgO, SiO2, CaO and depletion of TiO2, k.sub>2O and Zr might be link.d with carbonitisation, sericitisation, chloritisation, silicification and sulphidation link.d to gold mineralisations in the Birimian of Ghana.

Journal of Applied Mathematics and Physics 2024年第5期12卷 1835-1847页

作者： Henry Otoo Benjamin Dadzie mensah Lewis Brew Mathematical Sciences Department University of Mines and Technology Tarkwa Ghana Faculty of Science and Technology University of Silesia in Katowice Sosnowiec Poland

In this study, we prove the of existence of solutions of a convolution Volterra integral equation in the space of the Lebesgue integrable function on the set of positive real numbers and with the standard norm defined on it. An operator P was assigned to the convolution integral operator which was later expressed in terms of the superposition operator and the nonlinear operator. Given a ball Br belonging to the space L it was established that the operator P maps the ball into itself. The Hausdorff measure of noncompactness was then applied by first proving that given a set M∈ B r the set is bounded, closed, convex and nondecreasing. Finally, the Darbo fixed point theorem was applied on the measure obtained from the set E belonging to M. From this application, it was observed that the conditions for the Darbo fixed point theorem was satisfied. This indicated the presence of at least a fixed point for the integral equation which thereby implying the existence of solutions for the integral equation.

引用

Journal of Environmental Protection 2024年第4期15卷 379-400页

作者： Natasha Garcia Vaughan Thomas Alfred Addo-mensah Department of Biology & Chemistry Texas A&M International University Laredo USA

Manadas Creek.is an urban tributary of the Rio Grande that flows past a decommissioned antimony smelter and processing plant. This antimony plant is associated with heavy metal contamination in the creek.and still poses a threat to the surrounding aquatic environment. Corbicula fluminea was used to determine bioaccumulation from the water column and sediments in Manadas Creek. The metals arsenic (As), antimony (Sb) and thallium (Tl) were analyzed in the water, sediments, gills, mantle, foot, digestive (DI) tract, gonads and shell of clams being monitored at eight sites between March and August 2013. Sediment, water, and dissected Corbicula fluminea samples from different sites in the Creek.were acid-digested and analyzed by Inductively Coupled Plasma Optical Emission Spectroscopy. High levels of antimony (25.88 ug/L;75.96 mg/k.) and arsenic (8.26 ug/L;6.41 mg/k.) in the water and sediments were observed at the site downstream from the smelter. There were no detectable concentrations of arsenic, antimony, or thallium in the shell of C. fluminea. Arsenic and antimony were detected in the tissues of C. fluminea but thallium was not detected. Based on the results, the organotropism for arsenic is DI tract > gills > gonads > foot > mantle > shell and the organotropism for antimony is gills > DI tract > gonads > mantle > foot > shell. This study shows that the Asiatic clam (Corbicula fluminea) is a useful bio-monitor to provide data on the status of metal pollution in Manadas Creek. Laredo, Texas.

Investigation of Acoustomagnetoelectric Effect in Bandgap Graphene by the Boltzmann Transport Equation

World Journal of Condensed Matter Physics 2024年第1期14卷 10-20页

We study the acoustomagnetoelectric (AME) effect in two-dimensional graphene with an energy bandgap using the semiclassical Boltzmann transport equation within the hypersound regime, (where represents the acoustic wavenumber and is the mean free path of the electron). The Boltzmann transport equation and other relevant equations were solved analytically to obtain an expression for the AME current density, consisting of longitudinal and Hall components. Our numerical results indicate that both components of the AME current densities display oscillatory behaviour. Furthermore, geometric resonances and Weiss oscillations were each defined using the relationship between the current density and Surface Acoustic Wave (SAW) frequency and the inverse of the applied magnetic field, respectively. Our results show that the AME current density of bandgap graphene, which can be controlled to suit a particular electronic device application, is smaller than that of (gapless) graphene and is therefore, more suited for nanophotonic device applications.

Investigation of Groundwater Quality with Borehole Depth in the Basin Granitoids of the Ashanti Region of Ghana

引用

Journal of Water Resource and Protection 2024年第5期16卷 381-394页

作者： Bernard Ofosu Augustine k.fi Asante Festus Anane mensah Umar-Farouk.Usman Naa k.rk.i Ayeh Geotechnical and Materials Engineering Division CSIR-Building and Road Research Institute Kumasi Ghana

The dependence of groundwater quality on borehole depth is usually debatable in groundwater studies, especially in complex geological formations where aquifer characteristics vary spatially with depth. This study therefore seek. to investigate the relationship between borehole depth and groundwater quality across the granitoid aquifers within the Birimian Supergroup in the Ashanti Region. Physicochemical analysis records of groundwater quality data were collected from 23 boreholes of public and private institutions in the Ashanti Region of Ghana, and the parametric values of iron, fluoride, total hardness, pH, nitrate, and nitrite were used to study the groundwater quality-depth relationship. The results showed that the depth-to-groundwater quality indicated a marginal increase in water quality in the range of 30 to 50 m, which is mathematically represented by the low-value correlation coefficient (r2 = 0.026). A relatively significant increase occurs in the depth range of 50 to 80 m, which is given by a correlation coefficient of r2 = 0.298. The mean percent parameter compatibility was 74%, 82%, 89%, and 97% at 50, 60, 70, and 80 m depths, respectively. The variations in groundwater quality per depth ratio ranged from 1.48, 1.37, 1.27, and 1.21 for 50, 60, 70, and 80 m depth, respectively. The recommended minimum borehole depth for excellent groundwater quality is suggested with a compatibility per meter depth ratio of 1.37. This results in a range between 50 and 70 m as the most desirable drilling depth for excellent groundwater quality within the granitoids of the Birimian Supergroup of the Ashanti Region in Ghana.
