通过XRD、SEM和性能测试研究了Ca含量的变化对时效态Mg-6.5Al-xCa-1Sn-0.3Sr(x=1,1.5,2,2.5)镁合金的显微组织和性能的影响。结果表明,时效态合金主要由α-Mg和Al_(2)Ca相组成,Al_(2)Ca相成网状分布。合金的抗拉强度和伸长率随着Ca加入量的增加而逐渐降低,当Ca含量为1%时合金的拉伸性能最佳,而合金的硬度随着Ca的加入而增加。在175℃、70 MPa下,Ca的添加使时效态合金的稳态蠕变速率降低。

Background: The evolutionary profile of patients operated for peptic ulcer perforation in Bujumbura. Perforated peptic ulcer is a serious complication of peptic ulcer with potential risk of grave complications. Aim: To study the early morbidity and mortality of surgery for peptic ulcer perforation in Bujumbura City Hall hospitals: Kamenge University Hospital Center (CHUK), Kamenge Military Hospital (HMK) and Prince Louis Rwagasore Clinic (CPLR). Patients and methods: This is a retrospective, descriptive and analytical study carried out in the three hospitals of Bujumbura over a period of three years from January 1, 2020 to December 31, 2022. It involved 57 cases (n = 57) of peptic ulcer perforation. results: The frequency of surgery for peptic ulcer perforation was 2.7% with a mean age of 43.6 years +/- 15.3 years and a male predominance with a sex ratio of 3.7. Eight percent of patients presented with shock, 24.5% were smokers, and 67.9% had taken non steroidal anti-inflammatory drugs. The mean hospital stay was 15.2 days with a standard deviation of 12.1. The morbidity rate was 30.2%, 32% were classified in grade IIIb of the Clavien-Dindo Surgical Complications Scale. There were 9 deaths (17%). Seven patients who underwent surgery and received late consultations died. Conclusion: Surgery for peptic ulcer perforation remains an intervention associated with a high rate of morbidity and mortality in Bujumbura. Surgery for peptic ulcer perforation remains a procedure associated with a high morbidity and mortality rate in Bujumbura. The time before consultation was the only factor associated with early morbidity and mortality of Surgery for peptic ulcer’s perforations.

慢性疼痛是备受关注的公共健康问题之一,我国超过30%的人群受到慢性疼痛的影响,其发病机制是疼痛医学研究的热点与难点。中枢神经系统中固有的小胶质细胞在外界微环境改变时发生极化以及随之产生的神经炎症反应在慢性疼痛中至关重要。小胶质细胞在神经炎症反应过程中可极化为促炎M1型或抗炎M2型,分别在神经系统中发挥神经毒性或神经保护作用。本文拟对小胶质细胞极化的主要机制及其参与慢性疼痛过程的机制进行综述。

The red fruits of Pseudospondias microcarpa (A. Rich) Engl. are widely consumed by the populations of northern Congo for their sweet and tangy flavor as well as for their characteristic smell. The objective of this study was to show the food potential of the fruits of this plant for their valorization. Organic solvent extracts were prepared and subjected to phytochemical screening to determine the nutrients and phytonutrients of this fruit. Raw juice was extracted by trituration without adding water and subjected to physicochemical and biochemical analyses in order to determine its quality and its antiradical activity. The raw juice obtained is moderately acidic (pH 3.28), very cloudy and colored (turbidity of 1019 NTU). It has a dry matter content of 3.771% ± 0.013% reflecting the 70% dominance of water in the weight of the fruit and the presence of dissolved organic matter in its juice. Energy nutrients (sugars, amino acids), carotenoids, coumarins, tannins, flavonoids, terpenes and sterols have been highlighted as nutrients with therapeutic potential commonly called phytonutrients of this fruit. The juice presented a dominance in polyphenols (134.8500 ± 0.0023 mg gallic acid/100 g) than in carotenoids (5.100 ± 0.010 mg carotene/100 g), high levels of mineral macroelements (calcium: 3570.00 ± 2.05 mg and potassium: 4576.00 ± 9.49 mg) and trace elements (copper: 11.13 ± 0.10 mg, iron: 3.02 ± 0.03 mg and zinc: 2.57 ± 0.08 mg). These compounds exhibited good antioxidant activity. The presence of these nutrients and phytonutrients in these fruits is interesting for the proper functioning of certain organs and the prevention of certain diseases. This fruit is therefore an energizing and functional food that can compete with conventional fruits whose juices are marketed.

研究旨在建立一套准确、经济的团头鲂(Megalobrama amblycephala)家系鉴定体系,以期为团头鲂的遗传参数评估及基因组和分子标记育种奠定基础。精选8个高多态性的微卫星标记对二段法筛选后的228尾耐低氧快生长团头鲂“浦江2号”子代进行亲子鉴定分析,利用CERVUS软件分析实验结果。等位基因频率分析结果显示8个微卫星标记的平均等位基因数(N_(a))为8个,平均观测杂合度(H_(o))为0.813,平均期望杂合度(H_(e))为0.775,平均多态信息含量(PIC)为0.743。亲子鉴定结果显示双亲性别已知时8个微卫星标记的累积排除概率为0.9999,说明筛选出的8个微卫星标记适用于团头鲂家系的亲子鉴定分析。当使用筛选的8个微卫星标记进行亲子鉴定时,228尾团头鲂子代中有221尾子代能找到其父母本,实际鉴定率为96.93%,这与实际记录的系谱信息一致。研究成功地为筛选后的耐低氧团头鲂个体找到父母本并划分家系,为进一步开展遗传参数的评估工作奠定了基础。

We demonstrate a Ⅲ-Ⅴ-on-silicon-nitride mode-locked laser through the heterogeneous integration of a semiconductor optical amplifier on a passive silicon-nitride cavity using the technique of micro-transfer printing. In the initial phase of our study, we focus on optimizing the lasing wavelength to be centered at 1550 nm. This optimization is achieved by conducting experiments with 27 mode-locked lasers, each incorporating optical amplifiers featuring distinct multiple-quantum-well photoluminescence values. Subsequently we present a comprehensive study investigating the behavior of the mode-locking regime when the electrical driving parameters are varied. Specifically, we explore the impact of the gain voltage and saturable absorber current on the locking stability of a tunable mode-locked laser. By manipulating these parameters, we demonstrate the precise control of the optical spectrum across a wide range of wavelengths spanning from 1530 to 1580 nm. Furthermore, we implement an optimization approach based on a Monte Carlo analysis aimed at enhancing the mode overlap within the gain region. This adjustment enables the achievement of a laser emitting a 23-nm-wide spectrum while maintaining a defined 10 dB bandwidth for a pulse repetition rate of 3 GHz.
