Aphthona whitfieldi Bryant (Coleoptera: Chrysomelidae) is a major insect pest of Jatropha curcas L. in Burkina Faso. This study aimed at evaluating the effect of the insect pest populations’ density on the growth of the plant. To achieve this purpose, 90-day aged single plants were caged in a randomized complete block design experiment with 5 treatments and 5 replicates. The treatments consisted of increasing numbers of adults of A. whitfieldi used to infest the caged plants: T0 (0 adult = check), T1 (100 adults), T2 (200 adults), T3 (300 adults), T4 (400 adults). All caged plants were infested 21 days after transplantation and the evaluation started 14 days later one on every 2-week basis from September 18, 2014 to February 19, 2015. The growth parameters of the plant were assessed. The results showed that the intensity of damage caused by A. whitfieldi on the growth of young plants of J. curcas varied according to the treatment (i.e., according to the number of adult individuals infesting the plant at the beginning). The higher the number, the heavier the level of damage caused by the pest. So, the growth of the J. curcas plant was inversely proportional to the number of A. whitfieldi infesting individuals. There was also a positive linear correlation between the defoliation rate and the height of the seedlings. The status of this insect pest was confirmed by the results of this study.

Aim: To profile the diagnostic and the care provided for otological conditions in children. Method: This was a prospective cross-sectional study carried out from March 1, 2022 to May 30, 2022 at the eNT Unit of the Reference Health Center of Commune V (Bamako). This study concerned the records of children with an otological condition. They were at their first consultation within the unit. The month of March was devoted to recruitment. The follow-up was done until the end of May. The parameters studied included epidemiological, clinical and therapeutic aspects. Results: We identified 184 children suffering from otological conditions out of a total of 559 patients that consulted during March 2022, i.e. an hospital prevalence of 32.9%. This study found ear infections in 60.3%. earwax and epidermal plugs accounted for 32.60%. Traumatic injuries were 4.3%. Pre-lingual deafness was found in 1.1% of cases. Antibiotics were used for treatment in 66.3% of children without any complications detected. Conclusion: The otological affections of the child were frequent with a predominance of otitis.

In this study, two "quarter-size" mini-cyclones were developed to remove particles larger than 1.0 and 0.3 μm under a very low flow rate of 0.3 lpm, and two small impactors were also developed to remove particles larger than 0.3 μm at a low flow rate of 0.3 lpm. They are ideal devices to adapt to current instruments to prevent particle contamination/interference or work independently as a personal sampler. The geometric configuration of the mini-cyclones is referring to the extra-Sharp-Cut cyclone （eSCC） series [1]. However, the mini-cyclones were newly designed to reach the cutoff sizes （d50） of 1.0 and 0.3 micro-meter under 0.3 lpm, and the empirical equation provided by Kenny and Gussman cannot be used for predicting the d50 of these mini-cyclones. The nozzle dimensions of the small impactors are referring to the seventh sta.e of the Microorifice Uniform Deposit Impactor [2]. The performances of the mini-cyclones and the small impactor were evaluated in terms of penetration and pressure drop. To acquire the penetration curve and determine d50, the upstream and downstream particle distributions of the mini-cyclone and the small impactor were measured by Scanning Mobility Particle Sizer （SMPS, TSI Inc., Model 3096） and Aerodynamic Particle Sizer （APS, TSI Inc., Model 3321）. For mini-cyclone performance evaluation, four different flow rates, i.e., 0.3, 1.2, 1.6, and 2.0 lpm were tested. In general, the d50 decreases with increasing the aerosol flow rate. On the other hand, the pressure drops of both mini-cyclones and small impactors increase with the flow rate in a quadratic form. The performance of mini-cyclones was also compared with that of existing personal sampling cyclones. Further, empirical models to estimate the performance of the prototype mini-cyclones （i.e., the 50% cutoff particle size and pressure drop） were also established.

Introduction: Tibial plateau fractures are solutions of continuity of the epiphyseal-metaphyseal block of the upper end of the tibia of which at least one line enters the joint. They threaten the stability and mobility of the knee and can compromise walking and standing. These fractures are on the increase, especially affecting young and active subjects. Orthopedic treatment is a rare indication apart from non-displaced or slightly displaced forms. Surgical treatment is required in displaced forms, particularly in depression fractures. The aim of this work was to report the lesional and therapeutic aspects of tibial plateau fractures in our department. Patients and Method: Patients and method: This was a retrospective study over 36 months from January 2019 to December 2021. Included in this study were patients treated for a tibial plateau fracture in our department and followed up for at least 10 months. The epidemiological and clinical data analyzed were age, sex, affected side, etiology, mechanism of injury, pathological anatomy and associated lesions. The fractures were classified according to the classification of Duparc and Ficat. The slightly or non-displaced forms were treated orthopedically while the displaced forms were treated surgically. The minimum follow-up was 10 months. The results were evaluated by the anatomical criteria according to Mazas and Duparc and functional according to Merle d’Aubigné. Results: The authors collected 71 cases of tibial plateau fractures. They accounted for 4.0% of all limb fractures, 5.8% of lower limb fractures and 33.8% of knee fractures in our service. The male sex was the most represented at 78.9% with a sex ratio of 3.7. The age group of [20 - 40] years was the most affected, i.e., 53.5%. The average age was 41 years with extremes of 17 and 82 years. The left side was affected (n = 47) and the right side (n = 24). Road traffic accident was the main cause. The mechanism of injury was mainly represented by lateral and sag

针对导管螺旋桨的梢部流动,受压气机中“机匣处理”的启发,将矩形凹槽结构应用于导管内壁,用于降低导管螺旋桨梢涡强度和抑制梢涡空化,进而有望改善导管螺旋桨的水动力和空泡性能。采用计算流体力学方法,针对19A导管和ka4-70螺旋桨有无凹槽/不同凹槽结构进行非定常数值计算,研究凹槽结构对桨叶叶梢压力、梢涡强度、梢涡结构以及水动力性能的影响。结果表明:凹槽结构会明显改变导管螺旋桨梢部流场涡的形成,减弱梢涡强度,提高叶片梢部最小压力,并且对推进性能几乎没有影响。研究结果可为导管螺旋桨的梢涡控制以及减振降噪提供一种新的解决途径。
