In this work, we examine two algorithm schemes, namely, Kudryashov expansion and Auxiliary equation method for obtaining new optical soliton solutions of the discrete electrical lattice models in nonlinear scheme(Salerno equation). Our solutions obtained here are include the hyperbolic, rational, and trigonometric functions. Our two used methods are proved to be effective and powerful methods in obtaining the exact solutions of nonlinear evolution equations(NLEEs).

Bagzan mount is located in the Aïr massifs region. This locality, which is constituted only by the granites and volcanic formations, knows the difficulty of water supply that depends on rainfall. This present study has the objective of fracture mapping that allowed to the fractured aquifer in Bagzan mount. The methodological approach used has a treatment of Digital Elevation Model (DEM imagery), hydrogeological and geological approach in the field. This process allowed us to map the lineaments and elaborate a fracturing map after the validation stage. The fracturing map showed that the fractures network is distributed in the N70°-N80°, N60°-N70°, N50°-N60°, and two secondary directions N90°-N100° and N120°-N140°. These fracturing maps allowed us to have precious information in groundwater research in Bagzan mount, due to their geological and hydrogeological complexity.

The physical transformations in terms of contraction of okra dimensions during convective drying were examined. During drying, the lateral and longitudinal dimensions of okra decrease over time. The lateral dimensions go from their initial value to around 53%, 65% and 66% of this value after 530 min. The length of the two samples used goes from 8.65 and 9.02 cm to 6.79 and 7.52 cm after 14,300 min, i.e. a variation of 78.50% and 83.37%. All the two directions give variations almost linear depending on the water content. These linear contractions result in a volume contraction of the okra. It considerably decreases in volume during the drying process. The volume goes from 831.32 cm3 to 367.57 cm3 in min, a variation of 44.22%. The isotropic index reveals that okra does not behave the same in the lateral and longitudinal directions. It contracts its diameter more than its length.

The coast of Morocco is,in many locations, physically and socio-economically vulnerable to accelerated sea-level rise,due to its low topography and its high ecological,economic and touristic values. Assessment of the potential land loss by inundation and erosion,based on a modeling approach and Geographical Information Systems(GIS),has enabled to identify both locations and the socioeconomic sectors that

Background: Aneurysms of the internal carotid artery within the petrous temporal bone are extremely rare;their true incidence is unknown. The exact cause is unclear: they may be congenital or result from trauma, infection, or radiation. Aim: We report a case of massive otorrhagia and epistaxis from a ruptured aneurysm of the petrous internal carotid artery. Case Presentation: A 34-year-old man presented to our department for the first time with repeated left otorrhagia ongoing for 5 years, left sided pulsatile tinnitus and left conductive hearing loss. In his history, we noted a right hemi-corporeal deficit of sudden onset one month ago and the head-CT showed a left frontoparietal subarachnoid hemorrhage without any visualised vascular malformation. Otomicroscopy showed a pulsatile mass visible at the posterior part of the hypotympanum. There was a right-sided hemiparesis estimated at 2/5 with no disorder of the sensitivity. After hemodynamic stabilization, the patient was discharged from the hospital and treatment was scheduled in interventional radiology and neurosurgery unit. Unfortunately the patient presented at home with a cataclysmic hemorrhage by massive otorrhagia and epistaxis and arrived dead at the emergency unit. Conclusion: The treatment of a petrous carotid aneurysm must be carried out quickly considering the risk of rupture leading to a cataclysmic hemorrhage that can be rapidly life threatening.

Bambara groundnut (Vigna subterranea (L.) Verdc.) has economic importance for the producers and the traders as cash crop since it generates substantial income for households in Niger. The objective of this study was to assess eight (8) Bambara groundnut morphotype from Université André Salifou de Zinder in Niger Republic by their morphological and agronomic characters. The experiment was conducted in a randomized complete block design with three replications during the rainy season of 2020-2021. Data were collected on the Number of leaves, Plant height (cm), Growth habit (cm), Terminal leaflet length, Terminal leaflet width, Number of nodes/stem, Number of stems/plant, Number of pods/plant, Weight of 100 pods (g), Weight of 100 seeds (g), Length of seeds (mm), Width of seeds (mm), Weight of seeds/Plot (kg). There were significant differences for all characters, except Number of leaves, Terminal leaflet length, Terminal leaflet width, Length of seeds (mm) Weight of 100 pods (g), Weight of 100 seeds (g). The morphotypes UZ-VZ-04, UZ-VZ-03, UZ-VZ-06, UZ-VZ-02 and UZ-VZ-05 have demonstrated good performance for grain weight per plot and can be useful for a breeding program.

Okra, (Abelmoschus esculentus (L.) Moench), is grown as a sole crop and as a field crop in Niger. In the present study, three okra varieties from Zinder region in Niger Republic have been assessed for their agronomic performance traits. The experiment was conducted in a randomized complete block design with three replications during the dry season 2018-2019. The following characters were evaluated: emergence;germination;boutonization flowering;fructificaion;height at flowering;height at maturity;length of the petiole;diameter of leaves;diameter of plants;number of fruits;number of fruit per branch;total number of fruits;number of branch, number of leaves;length of fruits;diameter of fruits;number of arrets;weight of fruits;weight of seed, number of seeds. The collected data were subjected to analysis of variance (ANOVA) using XlStat version 7.1 and the means separated by using Turkey’s Method. Analysis of Principal components (PCA) using R software was also performed on the variables. There were significant differences for all characters except emergence, germination, diameter of plants, number of fruits, total number of fruits and diameter of fruits. The multivariate analysis by the ACP showed a grouping of the varieties in three groups. The three okra varieties have revealed good performances and could be useful for a breeding program. The study of the water needs of the varieties will be very interesting to make a better selection of the collection.
