Item ABUNDANCE AND SPECIES RICHNESS OF LOMBRIC MACROFAUNA IN A SEMI-ARID FOREST ECOSYSTEM(University of Eloued جامعة الوادي, 2017-09-01) Ababsa, N.; Laiche, A.; Djabbar, F.The importance of earthworms for soils has evolved over time. Our study was conducted in the forest of Ouled yagoub (North East Algerian). Sampling at three different altitudes resulted in a total of forty-nine individuals (49) and only three species were identified: Octodrilus complanatus, Allolobophora molleri and Aporrectodea rosea. Spread over two ecological categories. The specific richness is higher in the site of 1400 m of altitude. The Simpson index (Is) varies between 0.44 and 0.49 for the three study sites. The Shannon index fluctuates between 0.41 and 0.74. The values of the Hill index vary between 1 and 1.5 in the three Sites.Item ASSESSING OF WATER POLLUTION OF AIN ZADA DAM BY NUTRIENTS (NORTH-EAST OF ALGERIA)(University of Eloued جامعة الوادي, 2017-09-01) Mebarkia, A.; A. Haouchine, A.; A. Boudoukha, A.; Nedjai, R.In order to evaluate the impact of potential pollutions on the water quality in the watershed of the upstream of wadi Boussellem (North-east of Algeria), the evolution of the chemical composition of waters of the Ain Zada dam was studied over a period of ten years. Using a linear model of trends method, have been detected and quantified for the substances that are connected with the fertilizers and domestic effluents. An increasing concentration is observed for most of these substances. The increase of 88% in COD, 66% in BOD5 and the decrease of 4.3% in pH, suggests a degradation of O.M 85% by microorganisms. This degradation was accompanied by a decrease of 2% of O2dis content. The large increases of E.C 76%, NH4 290% and NO2 100%, are related to a marked increase in fertilizers applications and the denitrification of NO3 where latters declined by 77%. These increases are related also to the large amount of human and animal organic materials and industrial waste dumped.Item BEHAVIOR OF CEREAL€™S VARIETIES IN THE PRESENCE OF HETERODERA AVENAE WOLL (HETERODERIDAE, TYLENCHIDA) CYST NEMATODE IN TIARET AREA (ALGERIA)(University of Eloued جامعة الوادي, 2017-09-01) Labdelli, F.; Adamou-Djerbaoui, M.; Oulbachi, K.; Allel, A.The behaviour of cereals varieties (Ofanto, Waha and Vitron for durum wheat; Anza and HD1120 for bread wheat and Saida with Acsad for barly) were tested towards Heterodera avenae; The analysis of the variance reveals that the nematode has an effect on the development of durum wheat for the number of ear per seedling and the weight of thousand seeds, with respectively (P = 0,0033) and (P = 0,000) for the infested varieties and the witnesses. Common wheat shows a highly significant difference (P=0,0000) for the varieties infested and pilot and of the same for the barley, but with a significant difference with (P= 0,0002) between the varieties of barley. The two varieties of barley were different when with the weight from 1000grains. The ACP of any species confers that Saida is the most sensitive variety followed by Ofanto and Anza to attack of this nematode.Item BIOGAS AND CH4 QUALITY AND PRODUCTIVITY BY CO-DIGESTING DROMEDARY DUNG WITH KITCHEN WASTE AND SEWAGE SLUDGE WATER UNDER MESOPHILIC CONDITIONS(University of Eloued جامعة الوادي, 2017-09-01) Benaissa, K.; Dadamoussa, B.; Bendraoua, A.Five laboratory-scale studies were set-up to investigate the effects of dromedary dung (DD) co-digestion with kitchen waste (KW) and sewage sludge water (SSW) at five ratios, under mesophilic conditions (31-35°C) by examining operation stability, CH4 and biogas production potentials. The result obtained showed that KWDDSSW produced the highest CH4 content (64.51%), followed by DDSSW (51.37%) and DDKW (34.77%). The daily CH4 production was linearly correlated with pH, high volatile solids and COD degradation in the feedstock, indicating methane production was probably associated with higher supply of organic carbon source that favored the growth of active biomass. KWDDSSW and DDSSW were favored in terms of volume of flammable gas production of biogas and flamed on the 8th day. This study is being the first attempt on CH4 production of combined wastes with DD of Algeria.Item BIOLOGICAL CONTROL BY (COCCINELLA ALGERICA, KOVAR 1977) AGAINST THE PUCERON OF CROPS UNDER GREENHOUSES (STATION BIORESSOURCES OF EL OUTAYA CRSTRA) BISKRA; ALGERIA(University of Eloued جامعة الوادي, 2017-09-01)Inputs from chemicals, particularly pesticides, to control crop pests have adverse effects on soil and the environment, among others. To reduce pest attacks, biological control with indigenous predators is the alternative and the cleanest, most environmentally friendly and ecologically balanced way. In order to achieve this objective, we carried out ladybird breeding and releases were carried out on vegetable crops under glass in the Bioressources (CRSTRA) station where chemical inputs are not used.  This study shows that massive and successive releases larvae Coccinella algerica stage L3 and L4 (10 to 20 larvae C.algerica  and »350 individuals in Individuals in adult stage / infested plants)  reduced effectively the population of aphids.Item A COMBINATION OF SCALABLE ALGORITHMS FOR OPTIMISING PI CONTROLLER(University of Eloued جامعة الوادي, 2017-09-01) Laroussi, K.; Iratni, A.In several works using a single approach for optimization the parametres of PI controller confirms that the use of a single approach does not necessarily produce optimal results. In this paper, we propose to optimize the performance of the parametres controller by combining two scalable algorithms, genetic algorithms GA and particle Swarm PS, in order to optimize the parameters of the PI controller and to minimize the. By refining the parameters of controleur that monitor performance. Using a search engine that compares the error values of the different approaches and scenarios and, in each scenario, selects the results with the minimum error value. This method has been applied to control the speed of the induction machine. The results obtained by simulation show the high performance and robustness of this technique.Item COMBINING ABILITY AND GENE ACTION ESTIMATES FOR SOME YIELD ATTRIBUTES IN DURUM WHEAT (TRITICUM TURGIDUM L. VAR. DURUM)(University of Eloued جامعة الوادي, 2017-09-01) Hannachi, A.; Fellahi, Z.; Rabti, B.; Guendouz, A.; Bouzerzour, H.Item CONTRIBUTION OF ANTHROPIC ACTIVITIES TO THE SEAWATER POLLUTION AT THE PORT OF TENES.(University of Eloued جامعة الوادي, 2017-09-01) Guetarni, F.; Douani, M.; Kouadri Moustefai, S.The port of Ténès, located at West of Algiers, is a medium of intense anthropic activities. Its pollution was monitored using a sampling technique. The analysis of the parameters: pH, temperature, electrical conductivity and dissolved oxygen (D.O) was carried out in situ. The concentration of heavy metals has been carried out by the atomic absorption while scanning the wavelengths varying from 217.0 nm at 228.8 nm. The evolution of the nitrate and nitrite content was obtained by spectrophotometer. Their spatio-temporal profiles were obtained by the Geographic Information System (GIS) software. The high toxicity of seawater is due to the presence of lead and cadmium with concentrations exceeding 60 times the normal value (0.015 mg / l). Moreover, the deficit in D.O announces strong biological activities. This wild aggression is related to the industrial discharges in the port area.Item CONTRIBUTION TO THE STUDY OF THE EFFECT OF ORGANIC EXTRACTS OF BUNIUM INCRASSATUM ON THE HEMATOLOGICAL, OVARIAN AND UTERINE PARAMETERS OF MATURE FEMALE RABBIT(University of Eloued جامعة الوادي, 2017-09-01) Chentouh, S.; Boulahbel, S.; Ouldjaoui, A.; Hammoudi, N.; Djebaili, H.; Adjel, F.The objective of this study is to evaluate the impact of the organic extracts of Bunium incrassatum roots, belonging to the Apiaceae family, on some hematological parameter and histomorphological changes of the genital tract. This plant, called ‘Talghouda‘, is widely distributed in the east parts of Algeria. Phytochemical analyzes of the roots of this plant reveal the presence of two coumarins, scopoletin, scoparone Beta-sitosterol, sucrose and oleic acid. The study was achieved on mature rabbits of the local breed (Oryctolagus cuniculus) for 15 days. The animals were divided into five groups, which have daily administered 0, 25, 50, 100 and 200 mg/kg/day respectively doses of organic extract of Bunium incrassatum. The group with dose 0 was taken as a control. After treatment, the rabbits were sacrificed, the blood was collected in heparin tubes and their ovaries and uterus were removed and fixed in 10% formalin and then stained with hematoxylin-eosin. We found that treatment with the organic Bunium Incrassatum extract induces a significant decrease in the level of Triglyceride, Cholesterol in treated rabbits. The results of the histological study revealed a significant increase in the number of primary and secondary follicles in rabbits treated with 50 and 100 mg/kg/day doses and a decrease accompanied by an increase in atretic follicles in rabbits treated with a dose of 200 mg/kg/day, compared to the control group. The study shows that the organic extract of Bunium Incrassatum had estrogenic effects at doses of 50 and 100 mg/kg/day.Item CONTRIBUTION TO THE STUDY OF THE QUALITY PHYSICOCHEMICAL OF THE WATERS OF THE WATER OF THE COMPLEX TERMINAL IN THE VALLEY OF OUED SOUF (SOUTH-EAST ALGERIAN)(University of Eloued جامعة الوادي, 2017-09-01) Zaiz, I.; Zine, B.; Boutoutaou, D.; Khechana, S.The area of Oued-Souf consists of a good amount of underground water resources. These resources consist of two big aquifers: the Terminal Complex and the Continental Intercalary. The Chemical quality of these waters creates big problems like: the high mineralization and the concentration of some elements that surpass the recommended norms stated by the OMS. The objectives of the present study relate to quality of the waters within this area and their effects on the environment. According to the results obtained from the different methods utilized, diagram and statistical tool, it could be said that the mineralization of these waters is geologic in origin. The mineralization relate to the composition of the strata that make the two layers. The problem of the Oued-Souf area waters is in essence a problem of quality, for this we believe there must be some rigorous research to develop the chemical quality of these waters and to guarantee their accountability to the international norms before mobilizing them to the consumers.Item CORROSION OF A CARBON STEEL COVERED BY TREATED BENTONITES IN AQUEOUS SOLUTION(University of Eloued جامعة الوادي, 2017-09-01) Arbaoui, F.; Amzert, S. A.; Boucherit, M. N.In the present work we realised an electrochemical system for steel/clay/aqueous solutions study. Two Algerian bentonites have been considered. The obtained results show that both clays are corrosive even in the absence of chloride ions. We show that this corrosiveness is related to the cationic exchange capacity (CEC). The chemical treatment of clays by tungstate reduces significantly their CEC and corrosiveness. Electrochemical impedance spectroscopy results prove that tungstate reduce iron and chlorides ions transport through the clay. This deduction is supported also by microscopic observations.Item EFFECTS OF TEMPERATURE AND SALINITY ON THE SEEDS GERMINATION OF RETAMA RAETAM (FORSSK.) WEBB. SCARIFIED WITH SULFURIC ACID(University of Eloued جامعة الوادي, 2017-09-01) Mehdadi, Z.; Bendimered, F. Z.; Dadach, M.; Aisset, A.The present study consists of the elimination of tegumentary inhibition affecting seeds of Retama raetam by the chemical scarification. This pretreatment was carried out using pure sulfuric acid (98 %) and the seeds' germinative behavior was studied in the laboratory under controlled conditions of temperature and salinity. The results reveal that the chemical scarification by the sulfuric acid during six hours, had favored the germination of seeds which were incapable of germinating. The thermal optimum of germination expressed by the highest germination capacities and speeds as well as the shortest average times of germination and latency times corresponded to 20 °C and 25 °C. At low temperatures (0 °C and 5 °C) and high temperatures (35 °C and 40 °C), the germination was not possible.The seeds of R. raetam are sensitive to salinity, when the NaCl concentration increases the rate of germination decreases. The threshold of tolerance was recorded at 272 mM, from which the germination was inhibited.    ÂItem EFFICIENCY OF WASTEWATER TREATMENT BY A MIXTURE OF SLUDGE AND MICROALGAE(University of Eloued جامعة الوادي, 2017-09-01) Khaldi, H.; Maatoug, M.; Heilmeier, H.; Dellal, A.A combined system using the microalgae from South Africa and the sewage sludge from Algeria has been tested, in order to study the efficiency of wastewater treatment by mixtures of microalgae / activated sludge, five bioreactors were installed with different inoculation rates (microalgae / activated sludge) B1: 100% algae, B2: 90.90%: 9.1%, B3: 83.33%: 16.67%, B4: 50%: 50% and B5: 16.67: 83.33. The best removal percentages were measured as: 76.36% for PO4-P, 94.90% for NO3-N, 90.42% for NH4-N and 65.73% for COD, in the combined system. Except in the case of COD, there were highly significant effects of different inoculations rates on yield. The best results are those of the bioreactor B5. These results suggest that the nutrients in the wastewater can be effectively eliminated by co-cultivation of micro-algae with bacteria (activated sludge).Item EVALUATION OF THE EFFECT OF THE PECTINS OF THE DATES (PHOENIX DACTYLIFERA L) ON THE BIOCHEMICAL INDICATORS OF LEAD POISONING IN MALE WISTAR RATS(University of Eloued جامعة الوادي, 2017-09-01) Sadi, N.; Ouldali, O.; Bekara, A.; Aoues, A.This study is conducted to examine the effect of the oral administration of pectin of dates on perturbation of the biochemical parameters induced by lead. Male rats were exposed to lead acetate at 350mg/Kg for one month, after this period, rats treated during one month with the pectin of date at 3%. Rats were sacrificed, the blood and urine are collected for the biochemical assays: glucose, total protein, phosphatase acide (PAC), alkaline phosphatase (PAL), aspartate aminotransferase (AST), alanine aminotransferase (ALT), creatinine, urea and uric acid. The results showed that the exposure to lead has induced a disturbance in the biochemical parameters. Thus, the treatment by the pectin of dates reduced the high concentration of these parameters. Our results show that the pectins of dates may have a corrective effect on the biochemical disturbances induced by the lead.Item EXPERIMENTAL INVESTIGATION OF FLOW PATTERN AROUND REPELLING AND ATTRACTING T-HEAD SPUR DIKES ON FLAT BED(University of Eloued جامعة الوادي, 2017-09-01) Mahdieh Najafabadi, A.; Bateni, M. M.Use of T-head spur dikes is one of the common methods to control erosion of riverbanks. Nevertheless, setting spur dikes in the flow direction leads to modification of flow path and local scour in the site of the spur dike. In case of intensification, this can destruct the structure and the riverbank. Therefore, understanding its mechanism and characteristics are crucial. The main objective of this study is to investigate and compare the flow pattern around submerged attracting and repelling T-head spur dikes in a flat bed. The experimental Flume was a rectangular channel with bed width of 92 cm, bank height of 60 cm and length of 8.7 m. around spur dike at 24 cross sections, 16 profiles and 3 depths velocity was measured by 2-D electromagnetic velocimeter. The results showed that downflow in upstream of repelling spur dike is stronger than the downstream part and the Length of downstream circulation zone is larger in attracting spur dike.Item FABRICATION AND INVESTIGATION OF STRUCTURAL, OPTICAL AND DIELECTRICAL PROPERTIES OF BISMUTH TRISULFIDE (BI2S3) THIN FILM(University of Eloued جامعة الوادي, 2017-09-01) Benattou, H.; Benramdane, N.; Medles, M.Bismuth trisulfide (Bi2S3) in thin films was prepared by spray pyrolysis method at temperature of 280°c. The films were of orthorhombic crystal structure, and direct optical gap of 1.61eV. Tangent of dielectric losses, AC conductivity, dielectric constant and electric modulus were investigated versus the frequency (5Hz-13MHz) and the temperature (293-333°K). The single electric relaxation time is of order of nano-second and DC conductivity from 0.29 to 3.22 (Ω.cm)-1, were indicated from electrical analysis. The observed behavior was described in term of a multi-hopping process. The dependence of ‘σAC’ and ‘S’ with temperature, were interpreted by the model (CBH). The density of the localized states N(Ef) is of order of 1020 cm-3.Ω-1, the maximum barrier height WM of order of 0.1eV, and the activation energy (Ea ≈0.12eV ) were calculated for these materials.Item FATTY ACID COMPOSITION OF ALGERIAN PROPOLIS(University of Eloued جامعة الوادي, 2017-09-01) Rebiai, A.; Belfar, M. L.; Mesbahi, M. A.; Nani, S.; Tliba, A.; Ghamem Amara, D.; Chouikh, A.The fatty acid composition of eight honey bee (Apis mellifera) propolis load samples acquired in Algeria, were determined. The fatty acids presented a variable composition among these samples. All samples contained oleic, linoleic, stearic, eicosenoic, palmitoleic and palmitic acid. Only two samples did not contain arachidonic acid. Also results indicated palmitic, palmitoleic, linoleic, arachidonic and eicosenoic acid, respectively, accounted for 0.05% to 3.71%, 0.14% to 14.58%, 1.3% to 12.1%, 0.19% to 18.83%, and 0.23% to 12.86%; of the total lipids.The unsaturated fatty acid level varied from 19.72% to 51.85% of the total fatty acid composition, suggesting that propolis is a good source of unsaturated fatty acids to the diet. These data might help the regulatory agencies establish quality parameters for propolis produced in Algeria. There are no additional data available on Algerian propolis fatty acid composition.Item FREQUENCY AND COMPARISON OF SEROEPIDEMIOLOGY HSV AND CMV IN WOMEN WITH NATURAL CHILDBIRTH AND ABORTION IN SHAHID BEHESHTI HOSPITAL, ABADAN, IRAN(University of Eloued جامعة الوادي, 2017-09-01) Jomehzadeh, N.; Shahi, F.; Kooti, S.; Gorjian, Z.; Abdollahi L19orestani, H.; Tamimi, A.; Sobhani, A.; Khoshnood, S.Background: Cytomegalovirus and Herpes simplexvirus are one of the most common causes of congenital infections. Objectives: The purpose of this study was to determine the seroprevalence of herpes simplex virus type 1 (HSV-1), type 2 (HSV-2) and CMV antibody in pregnant women admitting to antenatal care clinic of Shahid Beheshti Hospital in Abadan, Iran. Serum samples were collected during the study. Methods: The enzyme-linked immunosorbent assay was used to detect anti-HSV-1, anti-HSV-2 type and anti- CMV. Socio-demographic and obstetric characteristics were used for further study. Results: Between January and December 2016, we have studied 325 pregnant women referred to Shahid Beheshti Hospital. The mean of women’s age was 27.66 ± 5.96 years old (range 16 to 43 years). Of the 325 participants in this study, 40 (12.3 %) were HSV-1 seropositive, 78 (24%) were HSV-2 seropositive and 36 (11%) were CMV seropositive. A combined analysis was performed for HSV-1 and HSV-2: the percentages of individuals testing regarding both HSV-1 and HSV-2 negative, both HSV-1 and HSV-2 positive, were 207 (63.7%) and 4 (1.2%) respectively.Item THE GEOGRAPHICAL DIMENSION OF CLIMATE DATA IN ALGERIA(University of Eloued جامعة الوادي, 2017-09-01) Bennour, T.; Guettouche, M. S.; Martinez Ibarra, E.In Algeria, implementation, monitoring and exploitation of climate data, development and dissemination of periodic publications and climate assistance to users, are tasks of the National Climatological Centre (NCC). Moreover, the effective management of this large volume of data requires the use of new technologies such as Geographic Information Systems (GIS). In this context, the aim of the present work is to develop an IT solution on the Web, based on the use of Geographic Information Systems. The approach consists, first, to design databases to store various data used (climatic and topographic) considering the functional needs such as the dissemination of data in several modes (read, download) and the possibility direct data access from remote locations. Then the choice of technology and tools to implement a mapping solution that will allow, in addition to the functionality of storage and distribution of different types of data, analysis of climate observations by using a web service whitin the WPS (Web Processing Service) standard.Item GEOMETRIC PROPORTIONS IN ISLAMIC ARCHITECTURE: CASE OF THE SIDI EL BENA MOSQUE IN TLEMCEN(University of Eloued جامعة الوادي, 2017-09-01) Hamma, W.The mosque of Sidi El Benna is one of the Islamic buildings of Tlemcen which dates from the Zianid era. As this type of style is characterized by the use of geometric proportions, for this reason we designed its planes, facades and sections after taking different measurements. Then, we compared the measurements of the heights, widths, lengths and angles of the different architectural elements in order to find arithmetic and harmonic proportions. We were able to find these last ones in particular the number of gold Φ which is equal to 1.618.  In addition, we could calculate the cubit of this time which is equal to 0.4375 m, it is almost equal to that of the Romans 0.444 m. Other principles of geometric composition are also found such as repetition and symmetry.
