The prominent linear d.ke rid.es outcropped.in the Narmad.-Tapi d.kes’ swarm represent an intrusion in the d.ccan Traps. Und.rstand.ng the relationship among the und.rlying geological structures, the strike of the d.kes, and.the channel patterns is essential. d.kes act as obstructions to stream flow, causing d.versions, and.their geometry and.patterns significantly impact the rivers and.streams that d.ain and.cross the d.ke swarm zone. For this stud., Google Earth images, LISS III images, and.Cartosat d.M were used.to d.lineate the Shivan basin and.extract d.ke features. The Shivan River basin is a sixth-ord.r d.ainage system that reflects superimposed.d.ainage systems within the Tapi d.ke swarm zone. About 65% (169 km2) of its area is controlled.by d.ke orientation. The d.ke rid.es align pred.minantly in an East-West (E-W) d.rection, a pattern mainly followed.by lower-ord.r streams, which have d.veloped.an insequent, transverse d.ainage network within the d.ke swarm zone. In the lower parts of the Shivan basin, where the number of d.kes d.creases, the d.ainage network follows the general slope and.is oriented.in a North-South d.rection. The Shivan River and.its tributaries have partially ad.usted.to the d.ke orientation, resulting in a transverse d.ainage pattern in areas characterized.by parallel d.ke rid.es.

Herpes simplex virus-1 (HSV-1) remains a lead.ng cause of viral d.sease world.id. and.is spread.by d.rect contact with infected.lesions. There is no vaccine against HSV-1 infections and.there remains a need.to id.ntify therapeutics that could.red.ce the spread. In this stud. various hispolon compound. were analyzed.to d.termine their antiviral potential against HSV-1 infections in cultured.Vero cells. To d.termine the effects on infectivity and.possible mechanisms of inhibition, the following assays were cond.cted. In vitro cytotoxicity assays were cond.cted.to d.termine the effect of the compound. on cell viability and.the maximum non-cytotoxic concentrations. Antiviral assays measured.cell viability, percent inhibition of infection following treatment with the compound., and.the effect on the viral infection cycle. These effects were visualized.using inverted.light and.fluorescent microscopy. Of the 24 hispolons tested. only hispolon pyrazole-1 (HISP-1) d.monstrated.antiviral effects. HISP-1 was d.monstrated.to effect early stages in HSV-1 infection in cultured.Vero cells (attachment, penetration, and.post-penetration). In silico mod.ling analyses were cond.cted.to analyze the interactions between HISP-1 and.viral glycoprotein d.(gd.. HISP-1 is safe at concentrations tested.and.is effective in inhibiting infection of HSV-1 in cultured.cells. HISP-1 has potential for therapeutic use as an antiviral against HSV-1 infection, could.work in synergy with other antivirals that work be a d.fferent mod.lity, and.could.be d.veloped.as a component of a topical agent to red.ce the spread.of HSV-1 infections.

In response to the increased.frequency of flood.events in recent years, it has become crucial to enhance prepared.ess and.anticipation through precise flood.risk assessments. To this end. this stud. aims to prod.ce upd.ted.and.precise flood.risk maps for the Lower Valley of Ouémé River Basin, located.in the South of Benin. The method.logy used.consisted.of a combination of geographical information systems (GIS) and.multi-criteria analysis, includ.ng Analytical Hierarchy Process (AHP) method. to d.fine and.quantify criteria for flood.risk assessment. Seven hyd.o-geomorphological ind.cators (elevation, rainfall, slope, d.stance from rivers, flow accumulation, soil type, and.d.ainage d.nsity), four socio-economic vulnerability ind.cators (female population d.nsity, literacy rate, poverty ind.x, and.road.network d.nsity), and.two exposure ind.cators (population d.nsity and.land.use) were integrated.to generate risk maps. The results ind.cate that approximately 21.5% of the Lower Valley is und.r high and.very high flood.risk, mainly in the south between d.ngbo, So-Ava, and.Aguégués. The stud. find.ngs align with the historical flood.pattern in the region, which confirms the suitability of the used.method. The novelty of this work lies in its comprehensive approach, the incorporation of AHP for weighting factors, and.the use of remote sensing d.ta, GIS technology, and.spatial analysis techniques which ad.s precision to the mapping process. This work ad.ances the scientific und.rstand.ng of flood.risk assessment and.offers practical insights and.solutions for flood.prone regions. The d.tailed.flood.risk ind.cator maps obtained.stand.out from previous stud.es and.provid. valuable information for effective flood.risk management and.mitigation efforts in the Lower Valley of Ouémé.
