Clay materials of the quarry of Bingerville (district of Abidjan) have been characterized by chemical analysis, X-rays diffraction, infrared spectroscopy and thermal analysis. These materials contain kaolinite (41% - 84%), illite (4% - 10%), quartz (14% - 27%), goethite (2% - 5%) and small amount of rutile (1%) that are not toxic minerals. They also contain some heavy metals which are beneficial to human biological activity (cobalt, copper, molybdenum, zinc) in tiny quantities. Some other heavy metals (lead, cadmium) which are considered as poisonous for human are present in very low content. The samples characterized by relatively fine grains are moderately crystallized. Their specific surface area varied from 26 to 43 m2·g—1. The mineralogical and physicochemical characteristics of these samples are like ones known for their healing properties. The consumption by internal way of studied materials, although it may be beneficial, requires a sifting to remove coarse grains (Φ > 2 μm) and a previous microbiological control.

This study examines the implementation and characterization of a polymer matrix composite material reinforced by sugarcane residues. The aim of the study is to enhance the abundantly produced sugarcane bagasse in the form of residues in the processing plants of said sugar cane. The composite material developed takes into account the size parameters and mass load rate of the reinforcement, the variations of which are between 2.5 mm and 4 mm respectively for the first parameter and 10% to 25% for the second. The load on the test tube during the test has a random orientation. The composite is polyester matrix. The cold compression moulding technique was used in the production of the various samples. Physical properties such as the rate of water absorption and the density of the composite are assessed. The three-point bending tests are carried out with the aim of inducing Young’s modulus from the elaborate samples. Analysis of physical properties shows that water absorption increases with the rate of residue load. The average water absorption rate of bagasse fibres is estimated at 8% for the 2.5 mm fiber size and 12% for the 4 mm fiber size for all composites. Mechanical characterization by bending tests reveals a fragile behavior of the samples tested. Young’s modulus decreases when the load rate of fibrous residues increases regardless of the size of the fibers.

利用色谱质谱(GC-MS)技术对中国及蒙古国不同气候区的26个深约20cm表层土壤中的类脂物进行了系统分析.讨论了在现代土壤中首次发现的含季碳的支链烷烃系列化合物,如5,5-二乙基烷烃、6,6-二乙基烷烃、5-丁基,5-乙基烷烃和6-丁基,6-乙基烷烃等.它们每个系列都只有奇碳或偶碳分布,明显指示生物来源,其碳数分布具有协变性.其中5,5-二乙基烷烃的分布同正构烷烃一样具有规律性的空间变化趋势,与气候和植被的空间分布有很好的一致关系.在湿热的东南和西南地区其低碳数组分占优势,主峰基本上为C21或C23;而在寒冷干旱的西北地区及蒙古国高碳数组分丰度较高,主峰基本上为C29.研究结果证明:和正构烷烃的ΣC?21/ΣC+21一样,5,5-二乙基烷烃的高低碳数分布优势作为一个新的独立指标,可以敏感地指示土壤生态和气候的变化.

The activity is related to the mineralogy and geological history of clays. Soils with the same value of the liquidity limit or plasticity index can have very different characteristics depending on the amount and type of clay minerals. The methylene blue value characterizes the activity of the clays and reflects the surface activity. Ten inactive soils contain minerals (kaolinite, illite), these soils absorb little water. Two swelling soils have normal activity and are composed of minerals (kaolinite, illite, Montmorillonite). The relationships between clayey soils properties, their activities and between the activity and the liquidity limit are defined. The correlations obtained are linear fit and exponential and sigmoidal fits. The correlations obtained with a coefficient of determination of R2 (0.859 - 0.999) can be used to characterize and predict certain parameters of fine-grained soils as a function of clay content.

Although the “triglyceride paradox” states that hypertriglyceridemia is less frequent in Blacks and the risk of pancreatitis increases with severe hypertriglyceridemia, we herein report on a case of moderate hypertriglyceridemia revealed by an acute chest syndrome and a milky appearance serum in a 47-year-old type 2 diabetes black patient with prior history of recurrent acute pancreatitis. In addition to insulin therapy and coronary angioplasty, the combination of a statin and a fibrate resulted two months later in a substantial improvement in triglyceride levels and a normal serum appearance.
