Item Covariance Correction For Estimating Groundwater Level Using Deterministic Ensemble Kalman Filter(University of Eloued جامعة الوادي, 2015-01-01) Behmanesh, J.; Bateni, M. M.The main problem in developing a groundwater model is to determine model parameters, particularly hydrogeologic coefficients, in a precise way. In this research, Deterministic Ensemble Kalman Filter (DEnKF) is described as a modern sequential method for data assimilation and a localization scheme within the framework of DEnKF is applied. Najafabad aquifer (in Iran) with area of 1150 km2, is modeled in the time window of Oct. 2000 to Sept. 2007 to obtain water table level data when its values of hydrogeologic coefficients calibrated and verified. DEnKF assimilated 45 observations of true run into the model with 2, 5, and 10 times of calibrated values of hydraulic conductivity and specific yield. This filter has been run both with and without use of localization. Results show easily-implemented localized DEnKF is favorably robust in groundwater flow modeling.Item Valorizations Environmental, Energy And Agronomic Of Biomethanisation Industrial Of The Avicolous Biomass(University of Eloued جامعة الوادي, 2015-01-01) M’sadak, Y.; Ben M’barek, A.This work consists in studying the anaerobie fermentation of the avicolous droppings on the level a digester pilot industrial. It was interested towards substitution partial of Forestry Compost (FC), produces locally in one seedbed except ground, by the avicolous methacompost refined in its two states, namely at the exit of decanter (AMCA) and at the exit of digester (AMCA') according one rate of 20%. The synthesis of the principal results is: the best assessments of depollution are obtained on the level of the mud tank as well concerning SM and DBO5; the incorporation of the avicolous methacompost with FC has a remarkable positive effect on germination, and consequently, on the growth of the seedlings of Acacia cyanophylla, in terms of height and of diameter; the best results of growth in height and diameter correspond to the mixture 80% FC + 20% AMCA'.Item Characterization Qualitative Of Soel For A Valorization Best Of The Biomass Produced(University of Eloued جامعة الوادي, 2015-01-01) M’sadak, Y.; Saad, I.The main objective of this study was to qualitatively characterize biomass of Solanum elaeagnifolium Cav. (or SOEL) to highlight the essential alternatives its valorization. At first, we studied the potential of composting biomass of this plant. The physico-chemical characterization of biomass silverleaf nightshade has detected a wealth in organic carbon, which highlighted the potential value of this plant in the Co-composting with other biodegradable waste. In a second step, we assessed the possibility to develop this plant in the area of treatment in textile effluents by biosorption of dyes on fibers from the biomass of this plant, especially after the discovery of high levels of cellulose in its different organs.Item Effect Of Heat Treatment On The Germination Of Seeds Soel(University of Eloued جامعة الوادي, 2015-01-01) M’sadak, Y.; Saad, I.The object of this work was to study the effect of thermal treatments (in the oven and in the compost) on the seed germination SOEL. The laboratory evaluation on the treatment in the oven berries at two temperatures (50°C and 60°C) for three exposure time ( one day, two days and three days) gave a germination rate zero for 60°C for an exposure time of one day. The spatio-temporal thermal monitoring of forestry compost windrow which was introduced to deal with berries SOEL showed a substantially homogeneous distribution of the temperature rising to 60°C and even longer swath stretching and used for a time period of 5 consecutive days. The germination rate was zero for all fruit seeds treated before the first reversal fact, regardless of the depth and location of the windrow considered that the berries were introduced. Thus, composting can be a solution to prevent the spread of SOEL by seed.Item Study Of Pathological Cases In The District Of Zguegue Elhedjaj In Laghouat(University of Eloued جامعة الوادي, 2015-01-01) Damene, Z.; Goual, M.s.; Bourzgue, T.; Daikh, Y.Laghouat is one of the prestigious Saharan cities of Algeria who inherits an architectural and urban heritage (habitat) of national importance. Zguegue El Hadjaj is one of the oldest quarters reflecting the historical and cultural value of the city. He is now in a very advanced state of degradation threatening the health, comfort and safety of its occupants. As part of the rehabilitation of old buildings and to preserve the historical heritage, this study is to identify the different forms of damage in this neighborhood and try to implement an approach to diagnosis and intervention suggestion on some pathologies. Our goal is not to solve all the problems, by cons we present the state of play in this neighborhood and the outlines of a rehabilitation technique through our acquired knowledge, which will serve as a reference tool and encourage the various actors to safeguard this heritage.Item Anti-inflammatory Effect Of Myrtusnivelleibatt&trab (myrtaceae) Methanolic Extract(University of Eloued جامعة الوادي, 2015-01-01) Touaibia, M.; Chaouch, F.z.This work aims at evaluating the anti-inflammatory activity of an endemic species ofthe central sahara: MyrtusnivelleiBatt&Trab. The methanolic extract of this plant was extracted by Soxhlet apparatus and concentrated under reduced pressure using a rotary evaporator. In the carrageenan-induced paw edematest, five different groups of mice were established and the extract was administered orally in three different doses. The dose of 400 mg/kg was able to reduce significantly the paw edema with a comparable effect to that observed with Diclofenac (positive control).This is the first report to demonstrate a significant anti-inflammatory activity of the methanolic extract prepared from Myrtusnivellei.Item Method Of Optimal Operation Of Small Dam In Irrigation(University of Eloued جامعة الوادي, 2015-01-01) Ladjel, M.In several Arab countries; agriculture is considered as the largest user of sweet water. This noble resource is distributed erratically by time and space. For the month of irrigation, this resource became scanty. That’s why; it is require to storage it; protect it and use it reasonably based on a deep knowledge of hydro meteorological policy and irrigation. This contribution is to propose the hydrological method of exploitation if the resource of water regulate by a small water dam. This is ascertained by the equation of the hydratical balance. Because it is possible to improve the yield of the water dam by the apliment of operating rules during irrigation season based on probabilistic projections of the fundamental components of the water balance.Item Rainfall-runoff Modeling In The Turkey River Using Numerical And Regression Methods(University of Eloued جامعة الوادي, 2015-01-01) Behmanesh, J.; Ayashm, S.Modeling rainfall-runoff relationships in a watershed have an important role in water resources engineering. Researchers have used numerical models for modeling rainfall-runoff process in the watershed because of non-linear nature of rainfall-runoff relationship, vast data requirement and physical models hardness. The main object of this research was to model the rainfall-runoff relationship at the Turkey River in Mississippi. In this research, two numerical models including ANN and ANFIS were used to model the rainfall-runoff process and the best model was chosen. Also, by using SPSS software, the regression equations were developed and then the best equation was selected from regression analysis. The obtained results from the numerical and regression modeling were compared each other. The comparison showed that the model obtained from ANFIS modeling was better than the model obtained from regression modeling. The results also stated that the Turkey river flow rate had a logical relationship with one and two days ago flow rate and one, two and three days ago rainfall values.Item Scanning Kelvin Probe Applied To Localised Corrosion(University of Eloued جامعة الوادي, 2015-01-01) Hussain, A.; Haque, S. K. M.This paper focuses on specific applications of the SKP system. The instrument is calibrated, using different thickness of a model polymer Poly Vinyl Butyral (PVB) on mild steel and on galvanised steel.Artificial defects are used to show how the instrument is capable of detecting a localised corrosion cell and its ability to picture the delamination of the coating from the steel substrate. An industrial application is undertaken with the instrument, where epoxy coated galvanised steel; with an introduced defect in the coating and various added inhibitors. Chromates and chromate replacements have been studied.Item Quality Of Imported Honeys Marketed In Algeria(University of Eloued جامعة الوادي, 2015-01-01) Haderbache, L.; Mohammedi, A.Honey is mostly used for therapeutic purposes, that’s why its quality must be closely monitored. This study focuses on the controle of 40 imported honeys coming from 13 countries (2004 – 2011). We revealedthat they do not always have the required quality to be consumed as such. In addition to the labeling and organoleptic problems, often they contains too much moisture (≥18%); 70 % of these samples had an average HMF of 78 mg/kg and a pH less than 3.5, indicating an advanced aging and inapropriate thermal past. Pollen analysis and electrical conductivity was used to confirm presumed origins, and proline rate reveals some inverted sugar fraud.We aim by this work to catchconsumers and localauthoritiesattention in order to strengthen honeycontrol. It is about everyone's health, and it concerns the prosperity of the national beekeeping which faces unfair competition.
