Abstract:
The fish fauna of sectors IV and V of the lagoon Ebrié, subject to seasonal influence of environmental variables was investigated. Fish were sampled using nets and cast nets between February 2014 and January 2015. At each ichtyological sampling, was associated physico-chemical parameter measurements. 57 fish species distributed in 50 genera, 33 families and 14 orders were identified. 49 species were recorded during the flood season, 47 in the rainy season against 32 during the dry season. Ethmalosa fimbriata, Chrysichthys nigrodigitatus, Trachinotus teraia, Gerres nigri, Tylochromis jentinki and Tilapia hybrid are the most common species (100%) whatever the season. The Kruskal-Wallis test showed that environmental variables were significantly different (p <0.05) from one season to another. The canonical analysis was used to observe the influence of environmental parameters on the temporal organization of the fish population. Indeed, during the dry season, it was noted that estuarine and marine species are majority because of the high values of conductivity parameters, salinity and sulfate. But in the flood season, these parameters with low values, were favored a important presence of freshwater species in the study area.

Abstract:
To upgrade the plastic hospital waste, our team has contacted several Kinshasa plastics companies (DUCAT, ECD, FRANCOPLAST, KINTAINERS, OK Plast and PLASTICA) to recover the resources collected in four hospitals (CUK, HGRK, HGRN and HGK) in Democratic Republic of Congo (DRC). They were contacted for recycling plastic waste (syringe, Baxter, plastic bottles) to produce the slippers worn by the poorest populations of the whole Republic. Our study took place from January 2009 to December 2009 and we gave five months from January 2010 to May 2010, each company selected to produce slippers. We selected three of six company because some had no proper infrastructure to accommodate the extra work. Similarly, it was necessary to add other personal and turnover does not allow it. Pursuant to the Sustainable Development Charter, we applied the methods Promethee-GAIA using Visual Promethee software to retain a company that would choose the decision-maker in recycling of hospital waste in plastic (or 400kg). We offer the decision maker the PLASTICA company that produces more slippers for personal average 6 out of the production line and lower cost of the pair occurred and the premium per hour.

New Algorithm to Segment Combinational Circuits in Pseudo-Exhaustive Testing
40-58
Mohamed H. El-Mahlawy and Winston Waller
Abstract:
In pseudo-exhaustive testing, the circuit is segmented into m output cones, and each out¬put cone is exhaustively tested. The test ensures detection of all detectable faults within the individual output cones of the circuit without the need for the fault simula¬tion. The use of pseudo-exhaustive testing is associated with certain costs. It includes the hardware cost of inserting segmentation cells to segment the circuit. In this paper, a new algorithm to segment combinational circuits is presented to reduce the hardware cost of inserting segmentation cells. In this algorithm, several heuristic procedures are proposed to handle different circuit topologies. The concept of limited global effect is presented. The limited global effect is to study the effect of a candidate node with respect to a particular subset of the nodes in its fan-out cone (FOC). Several approaches for the selection of the candidate nodes are presented, also. The experimental results for all combinational ISCAS85 benchmark circuits (F. Brglez, 1985) indicate the superiority of the presented algorithm in this paper with respect to all previous published algo¬rithms. Using the presented algorithm, no deviation of the number of segmentation cells from the expected behav¬iour for all cone size reduction values of all combinational ISCAS85 benchmark circuits between 16 to 32 is achieved - another improvement over previously published algorithms.

Testing of Spherically Blunted Rocket Nose Cone in an Open Circuit Low Speed Wind Tunnel
59-69
Hassan Khayyat and Ikramuddin Sohail Mohammed
Abstract:
“This paper is mainly concerned with creating a model of spherically blunted rocket nose cone and carry out the testing in an open circuit low speed wind tunnel to study the flow pattern around the nose cone. The model is developed and subjected to the pressure distribution analysis in the wind tunnel. Analysis of pressure involves the determination of dynamic pressure on various points marked on the surface of the nose cone. The process is carried out by connecting the probes inserted in the holes, made on the surface of the nose cone, axially and radially, to the pressure manometer and mobile Cassy. The process is carried out at different wind velocities and angle of attack. The results thus obtained pertaining to the different velocities for each material are tabulated and recorded.
After completing the tabulation of the results, graphs are obtained to make a clear idea about the pressure distribution along the nose cone. The curve of the graph explains us flow pattern of the wind around the spherically blunted rocket nose cone.”

Abstract:
Introduction: There has considerable evidence that persistent high-risk HPV infection (HR HPV) has a greater risk of developing cervical cancer.
Patients and Methods: This is a prospective study on three hundred women aged between 25 and 50 years old, screening for cervical cancer by Hybrid capture II (HCII) from 2012 to 2015. The aim of this study is to estimate the prevalence of HR HPV in Sidi Bel Abbes, and to identify the determinants factors of this persistent infection.
Results:
The results showed that the prevalence of HR HPV infection is about 7, 33% and the age of affected women is 39, 06±8 years. 95, 54 % of HPV tests were positive, and the average duration of the persistence of HR HPV infection was 18, 5 months [IC à 95%, 16.9-22.1 month].
Among determinants factor of this infection, the advanced age of patients (39, 06±8 years), the multiparity (76%), and viral factors (80, 94%). Other factors may be implicated, such as passive smoking (95%) and malnutrition (62%).
Conclusion: The risk of having a persistent high-risk HPV infection increases due to factors related to the patient.

Abstract:
Kinetics of adsorption in solid-liquid system can be controlled by several processes, such as external diffusion, interparticulate diffusion, chemical reaction, etc. Many chemical reactions which are important for water quality are carried out under simple law of rate of chemical reaction. Kinetics of these reactions can be described by reaction zero, pseudo-first and pseudo-second degree. Processes of copper ions adsorption on humic matter and barley straw as adsorbents have been researched at constant temperature versus time. Coefficient of adsorption has been quantitative determined and examined by zero, first and second degree models. Kinetics of copper ions adsorption from water solutions was examined at constant temperature (250C) and at different pH values. As commercial adsorbent was used humic acid, and as bioadsorbent was used barley straw. The results of adsorption shown significant efficiency in copper ions removal from water solutions by appliction of barley straw as bioadsorbent and have practical meaning in defining bioavailability of copper ions in water systems.
