Peel essential oil of bergamot （Citrus bergamia Risso） growing in Tunisia was separated by hydrodistillation and obtained in a yield of 9.7%. The oil composition was investigated using GC and GC-MS with two columns HP-I and HP-Innowax. Fifteen compounds accounting for 98.52% of the oil were identified. The oil was characterized by bigb content oflimonene （59.21%）, linalool （9.51%） and linalyl acetate （16.83%）.

工业科学是法国预科学校工程科学与物理(PSI)专业的必修课程,也是法国工程师大学校(Grandes Ecoles)入学考试科目之一,考生需要完成该课程理论和实验两部分的独立考试。在4个小时的实验考试期间,考生需要针对某个工程实际问题,依托实验设备,完成分析、计算、仿真、实验、口头陈述等多项任务;考试成绩则依据考生在考试过程中展示出的理解和分析能力、沟通交流和表达能力以及解决复杂工程问题的综合能力而定。该考评方法也在我院(北京航空航天大学中法工程师学院)工业科学课程的实验课中得到了应用。结果表明,这种注重过程和综合能力评价的考核方式和评价方法,可以较为客观有效地评价学生的综合实验能力,其考核标准可为我国实践教学环节的考核体系改革提供借鉴。

From medium-resolution satellite images (Landsat TM, ETM+ and OLI), the spatial dynamics of land cover and land use are highlighted. The objective of this study is to quantify the evolution of land use in the watershed of the Lobo River upstream of Nibéhibé between 1986 and 2019 in order to analyze the impacts of human activities on the landscape. The study method was based, on the one hand, on the processing of satellite images, for the analysis of the dynamics of land use and, on the other hand, on the CA-Markov model, for the prediction of land use by 2050. It emerged from this study that the land use maps produced made it possible to highlight the spatio-temporal dynamics of land use on the basin. For the period from 1986 to 2019, there is a decrease in the area of forests in favor of built-bare ground and crops and fallows. A land use scenario for the years 2019 and 2050 was simulated with an accuracy of 87.11%. The regressive trend in forests seems to continue in the future with current land use practices.

The Endengue Banded Iron Formation (BIF) is located in the northwestern edge of the Congo craton in Cameroon. Here, we report geochemical data of trace and rare earth elements (REE) of the Endengue BIF samples from the Archean Ntem complex and investigate their environmental setting. Two types of BIF occur at Endengue area, both containing minimal contamination from terrestrial material. Total REE (ΣREE) contents in the Type 1 BIF are extremely low, ranging from 0.34 to 1.83 ppm, similarly to pure chemical sediments while Type 2 BIF displays ΣREE contents ranging from 2.98 to 24.26 ppm. The PAAS-normalized REE + Y patterns of the two BIF types display LREE enrichment relative to HREE and weak positive Eu anomaly, most likely suggesting that the source of iron and siliceous of the Endengue BIFs is mainly from the contribution of low-temperature hydrothermal alteration of the crust. Type 1 BIF shows very low Nd content (* and positive Ce anomalies which suggests suboxic or anoxic seawater similar to the depositional environment of Elom BIF in Archean Ntem complex. In contrast, Type 2 BIF displays low to moderate Nd contents (1 and 100 ppm with the exception of sample LBR65) with negative correlation between Nd and Ce/Ce* and negative Ce anomalies. These features indicate precipa

Objectives: The aim of this study was to show an overview of situation of instrumental extraction at the maternity of Cocody University Hospital by determining availability and assessing the maternal and fetal prognosis. Patients and method: it was a retrospective study with a descriptive purpose on 6 months from January 1 to June 31, 2015. It concerned all patients admitted in the expulsive phase of labor delivery room and with an indication of fetal instrumental extraction and the state of their newborns at birth. Results: We saved 2288 vaginal deliveries;including 28 instrumental deliveries on 104 indications of instrumental extraction is an implementation rate of 26.9% (16 by vacuum extractor and 12 forceps). Among patients with indication but without instrumental extraction (n = 76), there is 42.3% vaginal delivery (n = 44) and 30.8% of cesarean section (n = 32). 44 have given birth vaginally (42.3%) and 32 by caesarean section (30.8%). It’s young patient (28 years), nulliparous (42.3%). Average time between instrumental extraction indication and the delivery of the baby was 58 min in the case of instrumental extraction and 1 hour 41 minutes in the case of spontaneous delivery in anticipation of the c-section. Motherhood had 3 instrumental extractors (2 vacuum extractors and 1 forceps) recycled after each use. The Apgar score was good in 85.7% in children born by instrumental extraction and bad in 54.5% in children born vaginally without instrumental extraction. We found 20 stillborn in intra partum occurred only in children born vaginally without instrumental extraction. Twelve (12) cases of bleeding of the issue by uterine atony (27.3%) were recorded in patients pregnant without instrumental extraction. No maternal deaths were observed. Conclusion: The realization of instrumental extraction rate remains low at the maternity of the UH-C. In the event, the fetal prognosis was better.

Located in the southwestern of the Oume-Fettekro greenstone belt, the Agbahou gold deposit is controlled by structural factors. Geophysics, teledetection and core data suggest the presence of NE and NW faults. However, the NE-faults define two major shear zones (ATZ: Agbahou Tectonic Zone and WTZ: West Tectonic Zone) that control the Agbahou gold mineralization. These first order structures are subparallel to the regional tectonic grain mostly north-east oriented. They seem to respectively develop on the both arms (eastern and western) of an anticline moderately plunging ~25° towards northeast. Each shear-zone contains several second-order shear-zones or lenses of variable direction and of 50° - 80° dip. NW-faults however correspond to strike-slip faults and their development should be related to transcurrent tectonics. They acted as control channels on the distribution of gold mineralizations. The ductile-brittle character of shear-zones favored the ascent of hydrothermal fluids and the formation of multiple auriferous quartz veins: veins Type IIa and veins Type IIb relating respectively to the shear-veins and extensional veins. However, Agbahou also shows the existence of a disseminated sulphides-bearing mineralization within host-rocks. At Agbahou, the precipitation of gold probably occurred in a post to late ductile-brittle deformation period.
