Surface-charged nanofibers were prepared by electrospinning technique (ESP). For this purpose, a copolymer bearing carboxylic acid functions was added to a poly(D,L-lactide) solution just before ESP process. In a basic medium, negative charges were therefore revealed on fiber surface. By deposition of positively charged particles or polyelectrolytes, surface properties of the fibers could be tailor-made for a specific application. This versatile method can, for example, be applied to the preparation of new biomedical scaffolds. [less ▲]

Hypertension is a common treatable risk factor for cardiovascular disease. Even when identified and treated, most patients with hypertension do not reach the blood pressure goal and they often need in fact three antihypertensive agents to achieve blood pressure control. Although various combinations of two therapies are currently available for the treatment of hypertension, development of more powerful therapies with 3 molecules is necessary to control more hypertensive patients. Amlodipine/Olmesartan/hydrochlorothiazide (Sevikar/HCT°) is a new triple combination of antihypertensive agents that lower blood pressure via calcium channel blockade, angiotensin receptor blockade and diuretic action. Its potent triple mechanism of action is also likely to attenuate compound-specific adverse events, such as amlodipine-related peripheral oedema or sartan-induced hyperkalemia. Moreover, by reducing the number of pills to be taken every day, the compliance should be better. Currently available data show that such a combination is very powerful and well-tolerated allowing more patients with all grades of hypertension (especially those with the most severe forms) to reach the blood pressure target. The contraindications are those of each compound. [less ▲]

This work is part of the research for appropriate methods for sustainable management of the sandy soils of the province of Kinshasa (Democratic Republic of Congo), in order to ensure and guarantee the adequate food security. It consists of a scientic research of the use of composts produced from household organic waste in improving the quality of sandy soils to the province of Kinshasa. The general objective pursued in this work is to evaluate the impact of four repeated applications of organic matter from bio-waste compost on chemical and biochemical parameters dynamics in acid sandy soils and their productivity. A pilot composting on a small scale has been installed for the production of composts from municipal solid waste and characterization of composts obtained has revealed the agronomic potential that presents this material. The diagnosis of the condition agropedological soils revealed that soils of the three study sites are sandy classified as rubics arenoferrasols (dystrics), have excellent physical conditions for drainage, air circulation and root penetration possess variables charges colloids, show an acid reaction, low organic matter and low nutrient minerals contents. In addition, their water and nutrients retentions capacity are very limited, and are the main soil constraints to agricultural productivity of these soils. After four growing seasons in real environments, the study of the reaction with the soil organic amendments (20, 40, 60 t.ha-1 MB) gave satisfactory results. The provision of continuous additions of organic composts significantly increased the values of pH, TOC, CEC, SB eff and reduced the rate of exchangeable Al saturation in the three sites. With the highest dose T3 (60 t.ha-1 MB), the pH increased at least 0.8 units and the carbon content multiplied by 2.5 to 3 on the three sites. CEC values increased from 3.3 to 5.02 cmol(+)mg.kg-1 and the toxic aluminum saturation decreased more effective than 90%. Regarding biochemical parameters (microbial carbon & nitrogen, RB, RIS, APA, Unt, Ut), compost treatments induced a significant improvement in function and doses applied throughout the experiment. These contributions have induced microbial activity which contributed to the increase in soil nutrients (N, P, ...) by microbiological activities. The availability of nutrients and fourniture of carbon by the composts explain these increases. In addition, yields on different test plants (Glycine max L. Merr, Arachis hypogaea L. and Hibiscus sabbariffa L.) were positively influenced by the treatments of organic composts household wastes. Compared with mineral fertilizers, their fertilizing potential is not negligible. According to the results observed, doses ≥ 40 t.ha MB-1 should be to keep and maintain an acceptable level of fertility and yields potentiel of crops. But low doses were more efficient than high doses of agronomic point of view. Doses ≤ 20 t.ha-1 MB are recommended in annual crop and regular. Phosphorus was found to be the most limiting element to agricultural production of soil sites studied whatever of the types of amendments and cultures used. Finally, the study indicates that for reasons of efficiency, availability and funds increased production may be obtained through synergy between the composts used in small quantities and fertilizer mineral supplements.

Edges is a fundamental clue for analyzing, interpreting, and understanding 3D scenes: they describe objects boundaries. Available edge detection methods are not suited for 3D cameras such as the Microsoft Kinect or a time-of-flight camera: they are slow and do not take into consideration the characteristics of the cameras. In this paper, we present a fast jump edge detection technique for 3D cameras based on the principles of Canny’s edge detector. We first analyze the characteristics of the range signal for two different kinds of cameras: a time-of-flight camera (the PMD[vision] CamCube) and the Microsoft Kinect. From this analysis, we define appropriate operators and thresholds to perform the edge detection. Then, we present some results of the developed algorithms for both cameras. [less ▲]
