The aim of this.paper is.to s.udy the exis.ence of integrable s.lutions.of a nonlinear functional integral equation in the s.ace of Lebes.ue integrable functions.on unbounded interval, L1(r+). As.an application we deduce the exis.ence of s.lution of an initial value problem of fractional order that be s.udied only on a bounded interval. The main tools.us.d are s.hauder fixed point theorem, meas.re of weak noncompactnes., s.perpos.tion operator and fractional calculus.

Earthquake induced lands.ides.are one of the mos. s.vere geo-environmental hazards.that caus. enormous.damage to infras.ructure, property, and los. of life in Nuweiba area. This.s.udy developed a model for mapping the earthquake-induced lands.ide s.s.eptibility in Nuweiba area in Egypt with cons.derations.of geological, geomorphological, topographical, and s.is.ological factors. An integrated approach of remote s.ns.ng and GIs.technologies.were applied for that target. s.veral data s.urces.including Terra s.r-X and s.OT 5 s.tellite imagery, topographic maps. field data, and other geos.atial res.urces.were us.d to model lands.ide s.s.eptibility. Thes. data were us.d s.ecifically to produce important thematic layers.contributing to lands.ide occurrences.in the region. A rating s.heme was.developed to as.ign ranks.for the thematic layers.and weights.for their clas.es.bas.d on their contribution in lands.ide s.s.eptibility. The ranks.and weights.were defined bas.d on the knowledge from field s.rvey and authors.experiences.related to the s.udy area. The lands.ide s.s.eptibility map delineates.the hazard zones.to three relative clas.es.of s.s.eptibility: high, moderate, and low. Therefore, the current approach provides.a way to as.es. lands.ide hazards.and s.rves.for geo-hazard planning and prediction in Nuweiba area.

The doleritic dykes.pres.nt in the Téra-Ayorou pluton cros.cut the bas.ment of the Nigerien Liptako and are part of the s.s.em of intrus.ve mafic dykes.in the Paleoproterozoic domain of the Léo-Man ridge. In the previous.work, emphas.s.was.placed on the petrology, geochemis.ry and geochronology of the Liptako doleritic dykes. This.s.udy aims.to analyze the tectonic s.yle of intrus.ve doleritic dykes.in the Téra-Ayorou pluton. The characterization of the deformation which affected the doleritic dykes.of the Téra-Ayorou pluton is.important for the evaluation of their economic potential. To this.end, meas.rements.of tectonic s.ructure planes.were taken in the field, and s.mples.were taken from the chilled margin and cores.of dolerite dykes. before being proces.ed in the laboratory. Analys.s.of the tectonic s.ructures.collected revealed a brittle tectonic pattern, characterizing a phas. of deformation s.bdivided into two epis.des.D1 and D2. Epis.de D1, with its.s.bvertically dipping normal faults.and s.mple N70˚ - N110˚ fractures. is.compatible with N-s.extens.on. On the other hand, epis.de D2, which created s.ear corridors.by reactivation of pre-exis.ing fractures.and oriented N150˚ - N170˚, is.as.ociated with a Ws.-ENE extens.on. Thes. res.lts.open up pros.ects.for the exploration of gold, uranium mineralization and diamonds.in the north-wes. of Niger.

Introduction: An omphalocele is.a congenital malformation due to a failure of clos.re of the umbilical ring with exteriorization of the abdominal vis.era covered by the trans.ucent and avas.ular amniotic membrane. We report a cas. of giant omphalocele unrecognized at birth followed by a review of the literature. Obs.rvation: This.was.a 4-year-old girl admitted to the department for umbilical s.elling that had been pres.nt s.nce birth. Clinical and paraclinical examinations.made it pos.ible to objectivize a pos.-omphalocele hernia with hepatic content plus.ectopic acces.ion of the left ureter, the s.rgical procedure cons.s.ed of reintroducing the liver as.ociated with a cure of the hernia + ureteroves.cal reimplantation. Conclus.on: Omphalocele is.a congenital malformation, antenatal diagnos.s.is.pos.ible during morphological ultras.und from the 12th week.

Introduction: Low back pain is.nowadays.a real public health problem in companies. The objective of the s.udy was.to determine the prevalence and factors.as.ociated with chronic low back pain among workers.of a mining company in Burkina Fas.. Material and Methods. This.was.a des.riptive and analytical cros.-s.ctional s.udy with a retros.ective collection that took place from Augus. 1, 2021 to March 16, 2022 in a gold mine in Burkina Fas.. It focus.d on mine workers.who participated in the 2019 annual medical vis.t. res.lts. Out of a total workforce of 880 workers.who took part in the annual medical vis.t in 2019, 165 had chronic common low back pain, i.e. a prevalence of 18.75%. The average age of low back pain workers.was.37.21 ± 7.5 years. among the workers.s.ffering from low back pain, 62 (37.58%) held the pos.tion of machine operator. Clinically, mechanical pain was.found in 113 low back pain workers.(76%) and twenty-nine (17.58%) had radicular pain. s.andard radiography of the lumbar s.ine was.abnormal in 129 workers.(78.18%. In the univariate analys.s. the factors.as.ociated with the pathology were s.x, level of s.udy, work s.ation and s.niority in the pos.tion. After a logis.ic regres.ion, the factors.as.ociated with its.occurrence were whole-body vibration (Fis.er’s.tes. = 12.7541;P = 0.000), male s.x (Fis.er’s.tes. = 8.363;P = 0.004), and s.niority for 4 to 5 years.(Chi2 = 4.0234;p = 0.046). Conclus.on: The s.udy reveals.the exis.ence of chronic low back pain cas.s.among the workers.of the mining company. There is.a predominance of the pathology in men, workers.expos.d to vibrations.and thos. with a s.niority of 4 to 5 years. It is.neces.ary to es.ablis. a policy of prevention of low back pain for the benefit of workers. in particular thos. expos.d to vibrations.
