Introduction: Fractures of the lumbar spine and thoracolumbar junction are common in spinal trauma. The aim of this work is to analyze the nature of the indications, the morbidity as well as the results of these treatment regimens. Patients and Methods: A retrospective, single-center study, based on a review of 64 patients with lumbar spine and thoracolumbar junction fractures (T10-L2) without neurological disorders, was collected in the neurosurgery department of the North Hospital and University Hospital (CHU), Marseille over a period of 2 years from January 2015 to December 2016. Posterior percutaneous osteosynthesis were more or less associated with kyphoplasty preceded anterior arthrodesis. Clinical and radiological endpoints were collected at least 6 months later. Results: The mean follow-up was 9.5 months (6 - 24). The clinical evaluation found a mean VAS at last follow-up at 14/100 (0 - 30) and an average Oswestry score at the last follow-up at 88%. The initial average vertebral kyphosis went from 13° to 4° at the last follow-up with a correction loss of 1°, an absolute gain of 8°. No postoperative neurological complications were noted in our series. Conclusion: The implementation of a two-step therapeutic strategy with anterior reconstruction in Magerl’s lumbar spine or A3.3 thoracolumbar junction fractures allows effective and long-lasting correction of lumbar lordosis and thoracic kyphosis, and obtaining a balanced spine in the sagittal plane. Our functional results are close to normal, with low morbidity and a low complication rate.

Effect of Technological Treatments on Cassava (Manihot Esculenta Crantz) Composition  [PDF]
Sahoré Drogba Alexis, Nemlin Gnopo Jean
Food and Nutrition Sciences (FNS) , 2010, DOI: 10.4236/fns.2010.11004
Abstract: The composition of cassava roots and those of its derived food (attiéké and semolina), were determined. The comparative study of the cassava roots composition with those of the semolina and attiéké has shown that the technological applied treatments in the preparation of cassava meal and attiéké influenced its composition. Thus, apart from the lipids content and energy values which slightly increased, all the components (protein, ash, cellulose, carbohydrates, starch and hydrocyanic acid) decreased in food derived from cassava.

Abstract: Samples of fresh Volvariella volvaceae, dry seeds of Irvingia gabonensis and dry seeds of Beilschmiedia mannii), three traditional vegetables found on the market in Abidjan were studied in relation to their nutrients composition (protein, fat, carbohydrates), energy value, moisture, ash and minerals (Ca, Na, K, Mg, Fe). The results show that: Volvariella vol- vaceae is mushroom distinguished by its high rate of moisture (81% ± 0.530% fresh matter), high carbohydrate content (79.440% ± 0.24% dry matter) and protein content (17.010% ± 0.04% dry matter) very significant. Mineral composition contains more Na (1.880% ± 0.02% dry matter) and K (1.260% ± 0.12% dry matter). Seed of Irvingia gabonensis is rich in lipid (63.610% ± 0.70% dry matter) but it also contains appreciable levels of carbohydrates (23.250% ± 0.17% dry matter), protein (7.230% ± 0. 80% dry matter) and mineral matter (5.910% ± 0, 30% dry matter). These seeds of Irvingia gabonensis contain more K (0.678% ± 0.01% dry matter) and Ca (0.452% ± 0.09% dry matter). Seed of Beil- schmiedia mannii is rich in carbohydrates (92.080% ± 1.20% dry matter), and has a significant protein content (7.160% ± 0.11% dry matter), its mineral composition contains more than K (0.872% ± 0.05% dry matter).
Collision Vehicle Detection System Based on GPS/INS Integration  [PDF]
Neda Navidi, Rene Jr. Landry
Journal of Computer and Communications (JCC) , 2017, DOI: 10.4236/jcc.2017.52006
Abstract: Continuous vehicle tracking as well as detecting accidents, are significant services that are needed by many industries including insurance and vehicle rental companies. The main goal of this paper is to provide methods to detect the position of car accident. The models consider GPS/INS-based navigation algorithm, calibration of navigational sensors, a de-nosing method as long as vehicle accident, expressed by a set of raw measurements which are obtained from various environmental sensors. In addition, the location-based accident detection model is tested in different scenarios. The results illustrate that under harsh environments with no GPS signal, location of accident can be detected. Also results confirm that calibration of sensors has an important role in position correction algorithm. Finally, the results present that the proposed accident detection algorithm can recognize accidents and related its positions.
Les gar ons et les filles du neuvième art 1970 - 1989

Genre & Histoire , 2009,
Abstract: La bande dessinée est un phénomène culturel de masse d’une ampleur qui fut largement sous estimée. Aujourd’hui il est de bon ton de se réclamer d’une culture “bédéphile” mais cela n’a pas toujours été le cas. Des avancées notables permettent de reconna tre la bande dessinée comme un pan non négligeable du paysage culturel du XXe siècle et les petits “miquets” sont révélateurs du contexte socioculturel dans lequel ils ont été produits. Le cinéma puise avec plus ou moins de bonheur dans ce vivi...

Agricultural Journal , 2013,
Abstract: Starches extracted from tubers of (07) species of wild yam (Dioscorea) have been studied with regard to the morphology and to the crystalline structure of their granules. The results revealed shapes and variable starch granule sizes and characteritics for every starch. These starches are constitued of granules with triangular, ovo triangular, ellipsoidal and polyhedric shape. Globaly the distribution of the granule size varies from 0.8 to 90 m. It is for starch granules of every uniform and asymmetric specie. The starch of D. dumetorum that has some small granules ( = 3 m) has a crystalline structure of A type and the other studied starches that have some thick granules ( = 25 m) have a crystalline structure of B type.

Positioning (POS) , 2013, DOI: 10.4236/pos.2013.42017

Global Navigation Satellite System (GNSS) technology is growing fast in our society and new applications are being introduced at an unprecedented pace. The GNSS products provide worldwide and real-time services using precise timing information, positioning and synchronization technologies. Within years, GNSS applications are becoming more accurate and their precision opens doors to a wide range of applications. Nevertheless, these applications are susceptible to disruption in the operation of GNSS receivers when malfunctions, failures or interference occur. This paper’s objective is to make an overall analysis of GNSS failure impact on society and therefore make a review of GNSS spectrum protection strategies. In the first three sections of this analysis, we survey GNSS applications, their importance and their criticality. While questioning the criticality of GNSS applications, we evaluate their impact on main critical infrastructures and particularly the risks of critical dependencies in case of failure or interference. In the last two sections, we investigate GNSS spectrum interference in relation to its effects on crucial infrastructures. We review the principal Radio Frequency Interference (RFI) sources leading to GNSS and satellite communications (SATCOM) spectrum issues. Alongside, we study various ways to mitigate RFI. This process is essential to further develop and standardize mitigation techniques and to ensure GNSS spectrum immunity against RFI.
