Trauma to the male genitalia is not very common and mainly affects a young population. There is probably a particular instinct in men to defend their external genitalia;indeed, in the flaccid state, the penis is little exposed, and fairly well protected and its mobility allows it to move with the impact of trauma and thus reduce the vulnating force. Open trauma is rare, as is testicular dislocation, the most common being closed trauma. Testicular trauma is an uncommon accident that affects young people. Trauma is most often caused by road and traffic accidents. Animal bites are rare, as is genital self-mutilation related to a psychiatric disorder. Surgical exploration is the rule except in cases of moderate testicular trauma. Our objective was to report our experience in an emergency context where treatment is poorly codified and to review the literature. We recorded four patients with external genitalia trauma managed in the urology department from April 2013 to March 2022. Our patients were children with open genitalia trauma following a traffic accident, scrotal injuries were encountered in three patients, and additional penile injuries in one patient. All patients were treated surgically. The follow-up was straightforward.

作者： modibo Kane TRAORE Key Laboratory of Enhanced Heat Transfer and Energy Conservation Ministry of Education and Key Laboratory of Heat Transfer and Energy Conversion Beijing Municipality College of Environmental and Energy Engineering Beijing University of Technology

Based on the analysis of computation methods and heat transfer processes of the parabolic trough receiver running in steady state, a two-dimensional empirical model was developed to investigate the thermal performance of heat loss of parabolic trough receivers under steady state equilibrium. A numerical simulation was conducted for the parabolic trough receiver involved in a literature. Comparisons between numerical and experimental results show that the empirical model is accurate enough and can be used to investigate the thermal performance of heat loss of parabolic trough receivers. The thermal performance of heat loss of UVAC3 and the new-generation UVAC2008 was investigated respectively. The simulation results show that selective coatings and annular pressure influence the thermal performance of heat loss of parabolic trough receivers greatly, wind velocity influences the thermal performance of thermal loss of parabolic trough receivers only a little in contrast with the emittance of selective coatings and air pressure in annular space. And the thermal performance of thermal loss of the new-generation parabolic trough receiver has been improved in a large amount.

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.

Postoperative complications represent important indicators for the quality of surgical care. The objectives of this work were to study post-operative complications in the general surgery department of the Cs ref of commune I in Mali, to determine the frequency of post-operative complications, to identify the factors of occurrence, to describe the clinical aspects, diagnostic and therapeutic in order to assess the additional cost linked to post-operative complications. This study was prospective, carried out in the general surgery department on 300 cases of surgical interventions. It covered all patients aged at least 15 years, operated on and hospitalized or not, and who presented complications during the 30 days postoperatively. Patients under the age of 15 were not included (our general surgery department is not a pediatric surgery department). We collected 300 patients among whom 199 (66.33%) were men and 101 (33.66%) women, i.e. a sex ratio = 1.9. The average age was 38 years with extremes of 15 and 87 years. The main initial diagnoses were: acute appendicitis, peritonitis, occlusions, wall hernias, hemorrhoids, uterine prolapse, uterine myomas, ovarian cysts and acute cholecystitis. Emergencies represented 43% (N = 129) of interventions with 6.98% post-operative complications (POC). Postoperative complications were dominated by surgical site infections, 75% of cases (N = 20), wall hemorrhage 5% (N = 1), testicular necrosis 5% (N = 1) and testicular calcification 5% (N = 1), wire rejection 5% (N = 1) and death 5% (N = 1). The management of postoperative complications was surgical in 95% and medical in 100%. Their occurrence extended the hospital stay by 3.65 days and increased the average cost of care by 60541.85 CFA francs. The mortality index lowered by efficient management of complications (IMAGE) calculated in relation to deaths was 95% of cases. Anemia, ASA score ≥ III, Alteimeir II and IV classes, duration of surgery and post-operative hospitalization were

Journal of Applied Mathematics and Physics 2024年第2期12卷 509-532页

In this paper, we treat the spread of COVID-19 using a delayed stochastic SVIRS (Susceptible, Infected, Recovered, Susceptible) epidemic model with a general incidence rate and differential susceptibility. We start with a deterministic model, then add random perturbations on the contact rate using white noise to obtain a stochastic model. We first show that the delayed stochastic differential equation that describes the model has a unique global positive solution for any positive initial value. Under the condition R0 ≤ 1, we prove the almost sure asymptotic stability of the disease-free equilibrium of the model.

Inguinal hernia in children is a congenital pathology in children linked to the persistence of the peritoneo-vaginal canal in children and the NüCK canal in girls;persisting into adulthood. This work aimed to study inguinal hernia in children in the general surgery department of the Reference Health Center of Commune I of the Bamako District;to determine the frequency of inguinal hernia;describe the epidemiological, clinical and therapeutic aspects of inguinal hernias and in order to evaluate the cost of treatment. This was a prospective study from April 2017 to March 2018 during which 60 children with an inguinal hernia were collected. Inguinal hernias in children represented 9.23% of patients operated on in the department. The average age was 59.23 months with extremes of one month and 180 months and a standard deviation of 49.23 years. The male sex was dominant with a sex ratio equal to 9:1. The notion of prematurity was found in 11.7% and was associated with a testicle not in place in 1.7% of cases. 41.7% of our patients were referred by a doctor and 66.7% of patients presented with painless, intermittent inguino-scrotal swelling (83.3% of cases). The hernia was discovered before one week of life in 50% of cases. Inguinal swelling was absent in 11.7% but observed intraoperatively. The inguinal hernia was unilateral in 91.7% of cases and 70% of hernias were discovered by the parents during pushing efforts. The inguinal hernia was located on the right in 61.7% of cases. The hernia swelling was soft, painless, impulsive and reducible in 78.3% of cases. The swelling was inguino-scrotal in 58.3% of cases. The hernia was simple in 95% of patients and hernial strangulation was observed in 3 cases or 5% of cases. 98.3% of patients were ASA I. The treatment was carried out openly in all our patients including closure of the vaginal peritoneal canal in 95% of cases under general anesthesia in 98.3% of cases. The morbidity rate was 8.4% (surgical site infection: 6.7% of ca
