The study evaluated the growth performance and carcass quality of CObb500 broilers fed two experimental rations incorporating feed and mango fine EDb>10b> for a batch of 83 birds, EDb>20b> (batch of 83 birds) in comparison with a commercial control ration CCD (84 birds). For this purpose, 250 day-old chicks of this breed were purchased in Korhogo and transported to Tengréla in Ivory Coast for rearing. The results show that substituting mango provender ans and mango seed flour for maize resulted in rations with costs per kgMS of 215.35FCFA, 2016.93FCFA and 320FCFA for the EDb>10b>, EDb>20b> and CCD rations respectively. The production costs per kg of chicken (FCPkgLW) of the CCD ration were significantly higher than those of the ED10 and EDb>20b> (p 0.05). ADGs were significantly different and decreasing from CCD, EDb>20b> to EDb>10b> (p 0.05). Average weights at 42nd day for EDb>20b> and CCD were homogeneous (p > 0.05) and significantly higher than for EDb>10b> (p 0.05). by day 49th the average weight of EDb>20b> had reached and exceeded that of CCD by day 42nd. PSLW, HCW and CCW were significantly different and decreasing from CCW, EDb>20b> to EDb>10b> (p 0.05). Average hot (HCY) and cooled (CCY) carcass yields of EDb>20b> and CCD rations were comparable (p > 0.05) and significantly higher than those of EDb>10b> ration (p = 0.009) and 0.003). Average drumstick and neck weights were significantly higher and lower for CCD, EDb>20b> and EDb>10b> (p 0.05). For all other parts of the cut, the average weights of the CCD ration were significantly higher (p 0.05) than those of the EDb>20b> and EDb>10b> rations, which were homogeneous (p 0.05). The incorporation of mango provender and mango seed flour in broiler rations offers the prospect of reduced production costs, less competition between man and animals over cereals, and lean meat production tha

Experimental Study and Thermal Modelling of Cocoa Shell Convective Drying in an Indirect Solar Dryer

引用

Modeling and Numerical Simulation of Material Science 2024年第2期14卷 69-78页

作者： Siaka Touré Adjo Christelle ogo Modibo Sidibé Solar Energy Laboratory FHb University of Cocody Abidjan C&#244te d’Ivoire

The concern of the present work is the convective drying of empty cocoa shells in an indirect solar dryer. Some drying experiments, using one sample, were carried out. During the experiments, the sample is introduced in the drying chamber. Then at steady time intervals, the sample is withdrawn from the drying chamber, for a rapid weighing. After each weighing, the sample is reintroduced in the dryer. At each time interval, the ambient temperature of the drying chamber and its relative humidity γ are measured by a thermo-hygrometer. From the experimental data, a theoretical determination of the moisture evaporated from the product was performed and a good agreement was found between the theoretical and experimental values, confirmed by the value of the RMSE. Those calculations used the constants in the Nusselt number found in literature. Then those constants were evaluated again, to get new values more suitable with the experimental data. The dimensionless numbers of Nusselt, Grashof and Prandtl were calculated. That allowed the calculation of the average value of the Nusselt number. The average convective heat transfer coefficient was determined.

Open Journal of Obstetrics and Gynecology 2024年第8期14卷 1176-1184页

作者： Yaméogo Rélwendé barnabé Sawadogo Amidou Kaboré Ahmed Komboigo béwendin Evelyne Dembélé Adama Somé Der Adolphe Souro Sanou University Hospital Bobo Dioulasso Burkina Faso Public Health Department of Joseph Ki-Zerbo University Ouagadougou Burkina Faso

background: Postpartum eclampsia is a life-threatening obstetric emergency. Its management is multidisciplinary. Despite measures taken to accelerate the reduction of maternal, fetal and infant mortality in burkina Faso, maternal deaths related to postpartum eclampsia persist. The aim of the study was to investigate the epidemiological, clinical and prognostic aspects of postpartum eclampsia in the obstetrics department of the Sourô Sanou University Hospital in bobo-Dioulasso. Method: This was a descriptive cross-sectional study with retrospective data collection covering the period from June 1, 2018 to May 31, 2019. We included 76 patients in the study;the variables studied were the epidemiological, clinical and prognostic aspects. The data collected were entered on a microcomputer and analyzed with the EPI info version 7.2 software. Results: The prevalence of postpartum eclampsia was 0.87% compared to admissions to the obstetrics department. The average age of the patients was 23 years old with the extremes of 15 and 39 years old. Primiparas accounted for 39.47%, housewives 53%, and home births accounted for 15.79%. Seizures accounted for 55% of the reasons for admission, the average time to onset of these seizures postpartum was 3.8 days with extremes of 1 and 30 days with 45% of seizures occurring postpartum immediately. Maternal complications were noted in 42.10% of cases with 5 cases of Hellp syndrome, 3 cases of renal failure, and 3 cases of acute pulmonary edema. We recorded 4 cases of maternal death, representing a case fatality rate of 5.2%. Conclusion: Postpartum eclampsia is common in the obstetrics department of the Souro Sanou University Hospital Center with a significant case fatality rate. Emphasis should be placed on monitoring and prevention, especially women at risk of developing postpartum eclampsia for better maternal prognosis.

South of Godé, in the central-western region of burkina Faso, granitoids of Paleoproterozoic age are similar to those of the Man/Leo shield. This study focused on the petrographic and geochemical characteristics of these granitoids, with the following results: 1) The tonalite that outcrops in the south-west of the study area belongs to the TTG group or first generation granitoids. They are most often ribboned at outcrop and have a geochemical signature close to that of Archean TTGs. Tonalite has a metaluminous character and the REE spectrum indicates that it may be derived from partial melting of basic magmatic rocks. 2) biotite granites have no outcrop structure. They are weakly metaluminous to peraluminous and potassic to highly potassic. Their rare earth spectra indicate that they may be derived from the partial melting of TTG granitoids. 3) Geotectonic diagrams show that the granitoids studied to the south of Godé were emplaced in an active tectonic context similar to that of present-day subduction zones.

The Pouni area is made up of basalts belonging to the boromo belt, lamprophyres and granitoids. These geological formations are similar to geological formations of the same type in other regions of the Palaeoproterozoic domain of the Man/Leo shield. This study, which focused on the petrographic and geochemical characteristics of these geological formations, led to the following main conclusions: The lamprophyres are basic plutonic rocks that cut through other geological formations. The basalt belongs to the northern part of the borormo belt and is thought to be a relic of overthickened oceanic plateaus. There are two groups of granitoid rocks. The granodiorite has a geochemical signature close to that of Archean TTGs and is metaluminous in character. It has a low potassium content. The minor element and rare earth element spectra indicate that it could be derived from partial melting of basic magmatic rocks. biotite granites are peraluminous and highly potassic. Minor element contents and rare earth spectra indicate that they could be derived from partial melting of felsic materials. Geotectonic diagrams show that the granitoids identified in the Pouni zone were emplaced in an active tectonic context, similar to that of present-day subduction zones.

This study, carried out in the Léo square degree (west-central burkina Faso) in the Palaeoproterozoic domain of the Man/Léo ridge, aims to define the shapes and positions of granitic plutons and the organisation of deformation structures using aeromagnetic data. These data have shown that there are small sub-circular granitic bodies to the north of the granitic masses in this region, and a large sub-circular granitic body to the south, around which are other smaller granitic bodies. The lineament map shows that the deformation structures are organised along three main directions and largely form these sub-circular plutonic bodies. We suggest that the granitic plutons are coalescent, pending identification of the internal structures of these granites to further refine the geodynamic model.

Introduction: Malaria eradication campaigns all over the world are largely based on parasite and vector control. Vector identification, whether morphological or molecular, is an essential component of vector control. This study analyzed the possible causes of indeterminate polymerase chain reaction (PCR) results for mosquito species in Western part of burkina Faso. Methodology: From July 2021 to November 2021, mosquitoes were collected during the period of high malaria transmission in the village of Séguéré, Houet province, burkina Faso, and morphologically identified. After DNA extraction, samples were amplified by sine 200× PCR to identify species of the Anopheles gambiae complex. Indeterminate samples were then selected for further analysis. The parameters studied were: DNA dilution, the effect of protocol adjusting, and the type of protocol used. Results: A total of 130 “indeterminate” DNAs diluted 1:10 were analyzed. After dilution, the mean amount was 14.73 ± 3.59 ng/μL and absorbance 1.71 ± 0.1. PCR chain reaction yielded 94.62% (123/130) anopheline species in SINE PCR, 5.38% (7/130) “negative”. A significant difference between SINE PCR before dilution and after dilution was observed (P be carried out to shed more light on the subject.

Gravity models given by higher-order scalar curvature corrections are believed to bear important consequences. Einstein-bel-Robinson (EbR) gravity with quartic curvature modification motivated Sajadi et al. to explore static spherically symmetric black hole solutions using perturbative methods. In this study, inspired by their work, we investigate AdS black hole shadows in EbR gravity and demonstrate how the gravity parameter alters the energy emission rate. Finally, we address the same problem in the presence of plasma, because the black holes are thought to be surrounded by a medium that changes the geodesic of photons.
