The purposes of this study were to describe and compare the techniques used by elite world triple jumper and the Algerian elite team to determine the impact of distribution modality phases allowing the elite to exceeds 17-meter. Our subjects were two world elite 2009 and two Algerian national elite 2013. In the lack of new technology Modem measuring instruments kinematics or kinetics, our study based in measure of the Phase distribution ratio as measure of Stride length Jump distance. That literature review two schools, the Russian technique （which emphasizes the hop phase） and the Polish technique （which emphasizes the jump phase）. Our aims for this study are： Are there any statistically significant differences between the results of the samples in the distance achieved？ Are there any statistically significant differences between practical Ratio relative distances （world 2009-national 2013）？ Are there any statistically significant differences between Stride length phase distances （world 2009-national 2013）？ For that, we have chosen the analysis of variance and correlation of the distances achieved in each of the phases with the official distance of jumper and ＂T＂ student to compare implementation distribution of phases （hop, step and jump） with the results accuses. Based on the practices and weaknesses of elites in practice, we confirm：（1） All the samples practice the Russian technique as model in the distribution of the phase ratio; （2） The problem of our elites is in the hop phase distribution and its relationship with other phases; （3） Improve achieve horizontal vertical velocity in hop phase as solution.

The study area, located in the Liptako basement of Niger, faces a serious problem of drinking water supply in recent decades. This is linked to exponential population growth and reduced rainfall. The purpose of this study is to map fracture networks from Landsat 7 satellite imagery to identify major subterranean flow corridors in the area. The methodological approach based on the collection of data (Landsat 7 images, DEM/SRTM, flow, transmissivity, static level) and the geological and hydrogeological field reconnaissance and the processing of these data with the following software (ArcGis, Envi, Surfer and RStudio) The results of this study yielded that the number of satellite lineaments is 995, the preferred directions of these satellite lineament are: N0°-10° (13%) and N90°-100° (12%). On the hydrographic network, in situ, the most frequent fracture, vein and dike directions are: N90°-100° (12%), N130°-150° (11%), and N50°-60° (10%). The structural domains identified probably correspond to the main corridors and reservoirs of underground flows. The values of the induced permeability are between 0.05 × 10-8 and 3.4 × 10-7 m/s. The permeability induced by satellite lineaments, which is strongly related to high fracturing densities and major water stream is involved in the hydrodynamic functioning of discontinuous aquifers in the study area.

The study was conducted in water marshes for five major marshes during the months of January, April and September of each region （Hawizeh, Hammer and the central marsh） in southern Iraq. Bacteriological analysis that some of the default pathological bacteria, including TC （Total bacterial count）, FCB （faecal coliform bacteria）, MPN （coliform bacteria） and FS （faecal streptococcus） can evidence to indicate of pollution. The results showed that most of the water samples examined pathological contain bacteria which indicates that the water is unfit for human consumption and the waters as basal （more hydrogen than No. 7）. There was a high salinity more than the permissible limits for human consumption and even to irrigate crops, and the same case for dissolve oxygen which exceeded are other limits as drinking water.

Crystalline manganese carbonate was found to be a versatile green, non corrosive and environmental friendly catalyst for transesterification of vegetable oils. Its use as catalyst in the transesterification process involving methanol and vegetable oils (palm, rapeseed, groundnut, coconut and caster oils) resulted in a conversion rate of 80% - 95% in the production of biodiesel. The chemical composition of the obtained biodiesel was studied by GC-MS analysis and showed the presence of linoleic, oleic, palmitic, and stearic acids methyl esters to be the major compounds. Manganese carbonate in comparison with other solid catalysts was found to decrease the reaction time and temperature concomitant with an increase of biodiesel yield. Finally, the effect of various parameters including methanol quantity, catalyst amount, reaction time and temperatures on the production of biodiesel was investigated.

Protective structures, built in the 1980＇s in order to reduce or stop coastal erosion in Rufisque, involved a modification of the coastal morpho-sedimentary landscape and have intensified the coastal dynamics. The diachronic study of beach profiles, before and after the seawalls construction showed that these protective structures accentuated the coastal erosion, with more important sedimentary deficits at the ends of the structures. Today, the Rufisque coast is characterized by a set of sedimentary cells whose morphological evolution and annual sedimentary dynamics are controlled by seasonal forcing： sedimentary deposits in dry season and erosion in wet season. However, this alternation of deposits and erosion phase shows spatiotemporal disparities. These disparities are very marked between a northwestern area characterized by concave profiles and a southeastern area （the bay of Rufisque） characterized by convex profiles and a much more important sedimentary deficit. The results also showed that these methods of shoreline protection are not durable measurements （degradation of the structures） and have exacerbated the vulnerability to coastal erosion as well as those of the coastal populations.

BRRI dhan70 is a new aromatic, high yielding and extra-long slender grain containing transplanted Aman rice variety which is an improvement over existing premium quality rice BRRI dhan37. BRRI dhan70 has pleasingly passed in the proposed variety trial conducted in the farmers’ field. As a result National Seed Board (NSB) approved this variety for commercial cultivation in the wet season (T. Aman) of Bangladesh in 2015. The important feature of BRRI dhan70 is the straw colored extra-long slender, higher elongation ability and aroma of the cooked rice. The growth duration of BRRI dhan70 is 130 days which is 10-15 days earlier growth duration than BRRI dhan37. Thousand grain weight of the variety is 20 gm and it has colored grain tip and pointed awn. The rice has 21.7% amylose content with 9.5% protein content. The special character of the variety is lodging tolerance. It has long, erect deep green flag leaf. BRRI dhan70 can produce 4.8-5.0 t/ha yield with proper management which is approximately 1.0-1.35 t/ha higher yield than BRRI dhan37. The exportable aromatic rice BRRI dhan70 is an excellent variety for cultivating in the wet (T. Aman) season and farmers can be benefited by the cultivation of BRRI dhan70.

Title: Assessment of haemostasis in anaesthesia for surgery at the Sylvanus Olympio University Hospital Center in Lomé. Objectives: Evaluate the prescription of the preoperative haemostasis assessment. Methodology: This was a prospective descriptive and observational study which had taken place in the central operating room and in the operating room of the ENT department at UHC SO of Lomé from January 1 to June 31, 2016. It had concerned all patients who had anaesthesia for scheduled surgery after pre-anesthetic consultation and the haemostasis assessment carried out according to the anaesthesia technique and the type of surgery. Results: Two hundred and sixty (260) patients underwent anaesthesia during the study period. The male sex predominated (60%), the age group 18 - 40 years predominated (50.4%). GA was more practiced (62.7%) followed by spinal anaesthesia (30.3%). Minor ENT surgery was more performed (28%). ASA1 patients predominated (48.5%). The pre-anesthetic haemostasis assessment including platelet count, prothrombin rate, activated partial thromboplastin time and bleeding time was almost always done. The platelet count was achieved in all patients followed by the activated partial thromboplastin time (94%). No haemorrhagic complication related to a haemostasis disorder was observed in the perioperative period in anaesthesia than in surgery. Conclusion: The prescription of the pre-anesthetic haemostasis assessment should not be systematic. It must take into account the clinical history, the patient’s bleeding history during the anaesthesia consultation, the type of anaesthesia, the surgery planned and the age.

Introduction: Intra-dural and extramedullary ependymomas are rare lesions. We report a clinical case confirmed by the histology supported by the neurosurgery department of Martinique University Hospital. Clinical, paraclinical and therapeutic data will be compared to a literature review. Observation: A 38-year-old patient was admitted for tetraparesthesia evolving since 3 months, associated with a left hemiparesis. The clinical examination revealed deterioration of the general condition and a tetrapyramidal syndrome. MRI of the cervical spine revealed extensive cervical extra-medullary intradural lesion of C3 to C5. The treatment had been an excisional surgery that had been subtotal in two stages, supplemented by craniospinal radiotherapy because the pathological examination had found a grade III anaplasic ependymoma. Conclusion: Because of their rarity, the treatment of these forms of ependymoma is not yet well codified.
