持续迅速上升的大气二氧化碳浓度([cO2])是全球变暖最大的驱动因子,但其作为光合作用底物直接增加了作物的生产力。相比c3作物,人们对未来高浓度cO2情形下c4作物的响应规律认识较少。与封闭或半封闭气室研究相比,FAcE(free-aircO2 enrichment)试验在空气自由流动的大田条件下对作物表现进行研究,它提供了对未来作物生长环境的真实模拟,因此提供了评估cO2肥料效应以及揭示植物响应机制的最好机会。作为人类重要的粮食和饲料来源,高粱和玉米是最重要的c4作物。在简介美国玉米和高粱FAcE系统的基础上,综述了FAcE情形下高浓度cO2(模拟本世纪中叶大气cO2浓度,即550μmol/mol)对两大作物生理、生长和产量以及土壤特性等方面的影响,同时比较了与气室研究结果的异同点。(1)FAcE使干旱条件下两作物光合作用显著增强,但湿润条件下没有影响;FAcE条件下高粱出现光合适应现象,而玉米没有;(2)FAcE使两作物气孔导度大幅下降,导致叶温升高、蒸腾速率下降、蒸发蒸腾总量减少或没有变化、叶片总水势和水分利用效率增加或没有变化;(3)FAcE对两作物物候期和化学组分影响很少;(4)FAcE使干旱条件下两作物生长和产量略有增加,但湿润条件下没有影响;(5)FAcE使高粱田土壤丛枝状菌根真菌的长度和易提取胶状物质浓度显著增加,导致水稳性土壤团聚体增加;FAcE对高粱田N2O或含氮气体(N2O+N2)的排放没有影响;(6)高浓度cO2对两作物气孔导度的影响FAcE试验明显大于气室试验,而对生长和产量的影响呈相反趋势。阐明cO2与基因型、土壤湿度和大气温度间的互作效应及其机制是下一轮c4作物FAcE研究优先考虑的方向,技术的不断进步已为利用大型FAcE系统来研究这些互作效应提供了可能。

context: The caesarean section rate continues to increase in our different health structures specially for women who have not had a scar in the uterus. Objectives: The aim of this study was to analyze the key factors and main indications for primary caesarean sections and to find ways to reduce the increasing rates. Patients and Method: This is a longitudinal and retrospective study carried out from June 1, 2018 to July 31, 2022. The study included all patients who had a cesarean-section for the first time (primary caesarean). An anterior uterine scar was a non-inclusion criterion. Data were collected prospectively using Synfonievre and Agopra software via patients’ files and information collection sheet. Data were analyzed with SPSS 21 software, Mac version. Averages were calculated for quantitative data and percentages for qualitative data. The statistical tests used were the Pearson chi2 test. The observed differences were considered significant when the p-value was less than 0.05. Results: During the study period, we recorded 8832 deliveries and 3148 caesarean sections (35.6%). Primary cS concerned 70% of overall c-section rate. The main indications were FHR Fetal Heart Rate abnormalities (FHRA) (27%), followed by the other indications (including preterm delivery, umbilical cord dystocia, malpresentation of fetus, foetal abnormalities, elective cS, triple gestation, mother abnormalities);dystocia or prolonged labor (18.7%), breech presentation in a twin pregnancy with 11.3% and 9.6% respectively. We recorded more vaginal deliveries with labor induction: 81.4% against 75.2%. An obstetrical audit led to better labor management and a reduction in the cesarean section rate. conclusion: We need to focus on diagnosis of fetal distress, management of breech presentation during of a twin birth and a singleton. Induction of labor can be an effective alternative in certain indications. An obstetrical audit is needed to reverse the caesarean section rate.

Peanut shells from Burkina Faso were characterized using mineralogical, microstructural and chemical methods to perform its possibility to be used as reinforce in adobe bricks. It consists of cellulose (48 wt%), hemicellulose (3 wt%) and lignin (28 wt%). The peanut shells were characterized by high porosity and showed water absorption around 198% at 72 hours. Its chemical composition is essentially composed of silica, iron oxides, alumina and calcium oxide. Its microstructure showed that the peanut shells were a compilation of microfibers with high porous of borders. In watery solution, the peanut shells released polyphenols. Thermal conductivity of peanut at 25 °c was 0.155 ± 0.021 W/mK. The physico-chemical characteristics of peanut shells were similar to those found with agricultural by-products used in adobe reinforce.

公共就业服务中的就业指导服务通常外包给服务提供商,本文聚焦于比利时和瑞士的公共部门与私营就业运营商之间如何开展协作。这种合作关系要应对两个挑战——招募培训项目的学员和衡量服务效果。我们最初的假设认为,在解决关键问题上利益相关者的博弈模式比合作框架模式更为有效。本文通过国际比较呈现不同的伙伴关系建立方法,以及利益相关者博弈和合作框架之间如何衔接。
