The perform.nce of m.cro flood irrigation （m.I） under different inflow rates was evaluated on 90 m.closed ended furrows in the South African Tukulu soil. A single irrigation was used to characterise the surface and subsurface soil water distribution from.the 20, 40, 80 and 160 L/m.n inflow rates treatm.nts. Neutron access tubes were installed to a depth of 1 m.at every 10 m.distance interval starting at 5 m.from.the furrow inlet. Soil water content m.asurem.nts were taken using the Waterm.n neutron water m.ter. The HYDRUS-2D software was also used to provide insight on irrigated furrows soil water content and subsurface water distribution. The 20 L/m.n produced a stream.flow that could advance up to the 60 m.furrow distance. The stream.flow from.the rest of the inflow rates were able to reach the furrow end with the 180 L/m.n recording the fastest advance tim. of 23 m.n. The 20 L/m.n and 40 L/m.n had recession period of less than 7 m.n while the 80 L/rain and 160 L/m.n lasted m.re than an hour. Distribution uniform.ty （DU） at longer furrow distances was the highest from.the 80 L/m.n and 160 L/m.n with the 20 L/m.n and 40 L/m.n recorded sim.lar perform.nces at shorter distances. The 40 L/rain was one of the sm.ller inflow rates that recorded the highest DU of 0.96 for the generated average infiltrated depth of the 30 m.long furrow and therefore should be adopted for furrow distances of less than 60 m.on the Tukulu soil.

The m.bile com.unication is nowadays one of the basic needs of hum.nity. It is essential to the flourishing of hum.n beings. Considering this reality, the need to use its m.bile phone is becom. m.re im.ortant and diversified. The subscribers of the various m.bile telephone operators are increasingly dem.nding. This situation poses the problem. of the cover m.bile network to the operators and leads them.to opt for several solutions and investm.nts. The m.bile operators in order to satisfy their custom.rs use a policy of pushing the lim.ts of network coverage in tim. and space for festive m.m.nts in targeted zones. Thus, we have conducted a study on the topic: study of a kit of GSm.radio site for event-driven m.vable coverage. This work is applied to GSm.(Global system.m.bile) network of the operator Orange-Ci, leader of m.bile telephony in Ivory Coast. We thus proceeded under investigation initially of the various aspects of the ordinary sites (m.tionless radio site) which are already deployed with Orange-Ci in order to im.regnate us infrastructures and equipm.nt used. This study revealed us that a radio site com.rises 4 parts: infrastructures, installations and energy equipm.nts, installations and radio equipm.nts, and installations and equipm.nt of transm.ssion. After the first analysis, we m.de a study of the m.vable site. The study of the m.vable site enabled us to see the various possible solutions to fulfill the basic functions of a m.vable radio site. After analysis we retained that our radio site will be built on a truck on which a m.st of 25 m.m.xim.m.length for the antennas will be em.arked, it will be fed by a generator also em.arked on the truck and the solution of transm.ssion selected is the transm.ssion by satellite m.re precisely technology VSAT. We choose the various equipm.nts (radio, transm.ssion, energy) according to features which we defined to constitute the kit of m.vable radio site.

Developm.nt of the spine and thoracic cage consists of a com.lex series of events involving m.ltiple m.tabolic processes, genes and signaling pathways. During growth, com.lex phenom.na occur in rapid succession. This succession of events, this establishm.nt of elem.nts, is program.ed according to a hierarchy. These events are well synchronized to m.intain harm.nious lim., spine and thoracic cage relationships, as growth in the various body segm.nts does not occur sim.ltaneously at the sam. m.gnitude or rate. In m.st severe cases of untreated progressive earlyonset spinal deform.ties, respiratory insufficiency and pulm.nary and cardiac hypertension(cor pulm.nale), which characterize thoracic insufficiency syndrom.(TIS), can develop, som.tim.s leading to death. TIS is the inability of the thorax to ensure norm.l breathing. This clinical condition can be linked to costo-vertebral m.lform.tions(e.g., fused ribs, hem.vertebrae, congenital bars), neurom.scular diseases(e.g., expiratory congenital hypotonia), Jeune or Jarcho-Levin syndrom.s or to 50% to 75% fusion of the thoracic spine before seven years of age. Com.lex spinal deform.ties alter norm.l growth plate developm.nt, and vertebral bodies becom. progressively distorted, perpetuating the disorder. Therefore, m.ny scoliotic deform.ties can becom. growth plate disorders over tim.. This review aim. to provide a com.rehensive review of how spinal deform.ties can affect norm.l spine and thoracic cage growth. Previous conceptualizations are integrated with m.re recent scientific data to provide a better understanding of both norm.l and abnorm.l spine and thoracic cage growth.

We described a sim.le and rapid m.thod to quantify sim.ltaneously chlorhexidine (CHD) and its m.jor m.tabolite, para Chloroaniline (pCA) by HPLC with UV detection without the additional need of m.bile-phase am.ne m.difiers or ion-pairing reagents, with good resolution between pCA and CHD, sym.etry peak of the com.ound and short run tim.. HPLC-UV analyses were perform.d using a Dionex? Sum.it liquid chrom.tograph (Dionex Corp, Sunnyvale, CA, USA). Chrom.tographic separations were carried out on a Luna? 150 m.×3 m. i.d. colum. packed with 3 μm.CN (cyano) particles (Phenom.nex?), guarded by an on-line filter. m.bile phase consist of m.thanol:water with sodium.chloride with 0.02% of form.c acid (55:45). Wavelengths for pCA and for CHD are 238 and 255 nm.respectively. Influence of m.thanol and of sodium.chloride content in the eluant has been studied. Linearity of CHD is very good, from.0.5 up to 21.2 μg/l while linearity of pCA is in the range of 0.05 to 10 μg/l with correlation coefficients above 0.999. Resolution between the com.onents is above 4, asym.etry is about 1.3 and 1.7 for pCA and CHD respectively and the run tim. is less than 5 m.nutes. This m.thod has been applied to CHD solution of different m.dical devices. No interference has been reported, and the analysis of direct injection of solution, without any treatm.nt is achieved in less than five *** conclusion, we present a validated m.thod for dosage of CHD and its m.jor im.urity pCA, known to be carcinogen, available into m.dical products or m.dicinal device for in-vitro diagnostic.

The prom.tion and the popularization of the m.cro concrete tiles in any locality obligation with a will of durable developm.nt pass by a standard of quality, which is based on the results of scientific and technical research taking account of local specificities. This work proposes to study the porosity of the m.cro concrete by m.cro structural analysis. From.this study, it com.s out that the variation of porosity com.ared to the ratio of the fine gravels (s/(s + g)) is decreasing. Indeed m.re the granular ratio increases less low is the density of pores of m.terial. The decrease of porosity according to the granular rate is not infinite;it tends towards a m.nim.m.starting from.a rate of fine gravel close to 50%. The results obtained justify well the ratio of fine gravel practised by tileries.

New paradigm. for processing and storing data such as cloud com.uting require new approaches for the m.asurem.nt of cloud service perform.nce. To establish a Service Level Agreem.nt (SLA) between a cloud service provider and its custom.rs, the cloud services and their service level objectives need to be identified. An additional challenge in the perform.nce m.asurem.nt of cloud services is the lack of m.dels that integrate the different perspectives of providers, m.intainers and custom.rs within the sam. m.del in order to define the concepts com.only used in cloud SLA contracts. This work proposes a three-dim.nsional Perform.nce m.asurem.nt m.del for Cloud Com.uting (P2m.C-3D) which consolidates perform.nce m.asurem.nt from.the perspectives of providers, m.intainers and custom.rs for the different types of cloud services.

m.Introductionm.: Worldwide, the incidence of kidney stones has been progressively increasing. Various factors can influence the risk of stone form.tion, including lifestyle and eating habits. The dietary investigation is a standard of care in patients with urolithiasis. The objectives of this study were to determ.ne the dietary habits of lithiasis patients in the city of Kinshasa and to investigate the association between dietary habits and the com.osition of the stones. m.m.terial and m.thodsm.: From.January 2017 to Septem.er 2019, 85 patients attending 8 hospitals participated in the nutrition survey. Various foods com.only consum.d in the Dem.cratic Republic of Congo were categorized based on their com.osition: foods rich in anim.l proteins, foods rich in calcium. foods high in sugar, foods high in oxalate, and various vegetables and fruits. We also investigated daily water intake. The com.osition of the collected stones was analyzed by infrared spectrophotom.try. m.Resultsm.: The m.an (SD) age of patients was 47.1 (14.0) years, 63.5% of patients were m.les, 75.3% of the patients had stones located in the upper urinary tract, and 7.1% were undernourished. m.st of patients consum.d vegetables (77.6%), anim.l proteins (62.4%), and foods rich in oxalate (58.8%). The daily water intake was less than 1500 m. in m.re than half of the patients (68.2%). m.jor anhydrous uric acid stones were associated with a high body m.ss index (p = 0.025). m.le patients with a high oxalate diet had m.re calcium.oxalate stones (64.3%) com.ared to other types of stones (p = 0.041). m.Conclusionm.: High consum.tions of vegetables and low water intake were linked to the form.tion of calcium.oxalate m.nohydrate stones. m.re data are needed to confirm.these findings.

The Gondo plain lies between m.li and Burkina Faso and it is in interland basin into the West African Craton. Since 2003, this study has been carried out two research projects on the southwest part of the plain, where the piezom.tric levels are very low （50 m.to 100 m.. It has two m.in purposes： find water resources to provide drinking water supply to Ouahigouya town and assess the exploitation possibility of the deep aquifer for rural water supply. Com.ined m.thods were used to reach the objectives of this study--rem.te sensing, geology, geophysics （electrom.gnetism.and resistivity m.thods）, hydrochem.stry and isotope chem.stry. So, the m.thodology allows to specify the geology and the tectonic of the eastern border of the basin, identify and characterize the different aquifers and their relationships. Through the im.lem.ntation of 250 m.deep drilled boreholes, this study reveals that the water level of the lower Cam.rian lim.stones can be under pressure below the continental term.nal deposits. The study highlights paleo-karstic zones in the Gondo plain and shows that water chem.stry and isotope chem.stry can be used to differentiate water sheets and evaluate their recharge.
