FLOODS TYPOLOGY IN SEMIARID ENVIRONMENT: CASE OF AIN SEFRA WATERSHED (KSOUR MOUNTAINS, SAHARIAN ATLAS, SW OF ALGERIA)
(university of el oued/جامعة الوادي, 2017-04-21) . Derdour*, A; . Bouanani, A; Babahamed, K
The watershed of Ain Sefra covers an area of 1957 km2, which is located in the southwestern of Algerian territory in an area called Ksour Mountains. It is moderately elongated and characterized by a fairly widespread network, steep slopes and relatively impermeable terrains with variety lithology, providing a favorable environment for the development of flashfloods. The surface flow regime in this semi-arid region is consistent with the rainfall. Floods are highly variable and irregular, short and stormy, with very high peak flows if compared to the average modules, they are characterized by a very fast rise, leading severe damages in Ain Sefra city, and a slow decline followed by a prolonged dry period. Autumn is reported as risky season. The flow in dry periods demonstrates a groundwater potential, which is produced by the Atlas relief that shows a fairly strong hydrological relationship between surface water and groundwater
COMPOSITION, ANTIBACTERIAL AND ANTIOXIDANT ACTIVITIES OF ARTEMISIA HERBA-ALBA ESSENTIAL OILS FROM ALGERIA
(university of el oued/جامعة الوادي, 2017-07-01) Hamzaoui, N. Dahmani-; N., Sabaou3,; S., Salido
The essential oils of three individual plants of Artemisia herba-alba, growing wild in tree different locations from Bordj Bou Arrérridj in East Algeria has been extracted by hydrodistillation and a microwave distillation process. The main components were α-thujone (35.1 and 31.2% in HD and MD oils, respectively) for Draâ Ech, davanone (39.6-37.3%) and 1, 8-cineole (9.2-7.8%) for Bordj Ghédir, chrysanthenone (29.6-43.8%), camphor (18.6-16.0%), and α-thujone (15.9-8.6%) for Bordj Bou Arrérridj. In comparison with HD, MD allows to obtain oil in a very short time, with the comparable qualities and substantial saving of energy. The minimum inhibitory concentration of various essential oils shows a power inhibitor not exceeding 10 µg/mL against all microbial strains. The three chemotypes were slightly active, and the weak DPPH radical scavenging activity of these oils could be attributed to the absence of some phenolic components.

EXPERIMENTAL STUDY OF THE VENTILATION OF STOCKED WHEAT IN A SILO
(university of el oued/جامعة الوادي, 2018-09-01) Hussine, A; Bettahar, A; Youcefi, A
This work is an experimental study of the ventilation of durum wheat stored in a silo of reduced dimensions and equipped with a ventilation system. The wheat, freshly harvested in June of the year 2015, was put in the silo. It underwent first drying ventilation during which we compared the influence of three air velocities on the evolution of the water content of the grains and their temperature. The set velocities are: 0.10 m/s, 0.15 m/s and 0.24 m/s. Two other ventilations were carried out in October (2015) and in January (2016) with an air velocity of 0.24 m/s. The results obtained allowed us to conclude that the ventilation of the wheat is necessary as soon as it is put in the silo to cause its drying. On the other hand, it allows the heat generated and the cooling of the wheat to be evacuated in autumn and winter. Drying and cooling were carried out in successive layers before stabilizing. There is therefore a transfer of heat and humidity by forced convection.

(university of el oued/جامعة الوادي, 2018-09-01) Zaghdi, S; Laouini, S. E; Bebba, A. A
The aim of this study is to highlight the ability of plants to purify wastewater with a horizontal flow system under a dry and hot climate. The process consists of circular beds with a capacity of 30 L filled with superimposed layers of gravel (25/15) mm, sand, 45 cm and 10 cm deep respectively. The first bed was planted with freshly collected stems of the plant Papyrus alterniofolius (40 stems/m2) and an unplanted bed was taken as a witness. The results revealed important removal fractions of the main pollutants namely: chemical oxygen demand COD (70,59%), biochemical oxygen demand BOD5( 97,25%) total suspended solids TSS (97.16%), nitrite NO2– ( 65.55%), nitrate NO3-(86.16 %), E. coli (99.41%), total coliforms (99.97 %) and total streptococcus (99.90 %). The considerable decrease of pollutants content and harmful organisms enables the reuse of the treated water in agriculture and industry.
PARASITIC ACTIVITY OF TWO PARASITOIDS PHANEROTOMA FLAVITESTACEA FISHER AND BRACON HEBETOR SAY (HYMENOPTERA: BRACONIDAE) ON THE DATE MOTH APOMYELOIS CERATONIAE ZELLER (LEPIDOPTERA: PYRALIDAE)
(university of el oued/جامعة الوادي, 2018-09-01) Zouioueche, F. Z; Biche, M; Mehaoua, M. S
The parasitic activity of the two parasitoids Bracon hebetor and Phanerotoma flavitestacea significantly affects the biological development of date moth Apomyelois ceratoniae. The results showed the females fecundity of both parasitoids is positively correlated with the number of host individuals (Phanerotoma: r = 0.46 and p <0.0001, Bracon: r = 0.7 and p = 0.001). Also, a significant difference is recorded between parasitized eggs and larvae and the number of emergences of adults of both auxiliaries with p = 0.001. In addition, the results revealed a very low rate of parasitism in P. flavitestacea compared to B. Hebetor with respectively 57.83% and 100%. Therefore, this study can enable us to valorize the use of these indigenous auxiliaries by combining the parasitic activity of egg-larval parasitoid with that of larvae, as a complementary action able to improve the success of biological control programs against the date moth.

MATHEMATICAL OPTIMIZATION OF SUPERCONDUCTING MAGNETIC ENERGY STORAGE FOR WIND ENERGY SYSTEMS
(university of el oued/جامعة الوادي, 2018-09-01) Paul Antony, A; Shaw, D
Wind variability coupled with conditional changes in the level of energy consumption has made the need for energy storage unavoidable in increasing wind energy penetration. The quest for an environmentally friendly device with fast dynamic response and nearly infinite cycling has resulted in superconducting magnetic energy storage (SMES) being proposed as a novel storage technology for wind energy systems. This paper builds on previous work in our lab that uses a magnesium diboirde SMES to address wind interruptions. Mathematical optimization was conducted to design large capacity toroid storage specifically to address sustained interruptions from wind turbines. The toroidal configuration consisting of 4 modules exhibited the highest normalized efficiency with least superconductor requirement

MAXIMUM FLOW OF RIVERS OF THE UKRAINIAN CARPATHIANS (IN THE UPPER DNIESTER) IN THE CLIMATE CHANGE CONDITIONS
(university of el oued/جامعة الوادي, 2018-09-01) Melnyk, S; Loboda, N
The complex nature of the flow of the Carpathian Mountains necessitates the identification of current trends in the changes in the maximum flow with different genesis (spring flood and rainwater floods). The studies were carried out over a period of the years (1961-2010) and various phases of water content. Statistically significant trends were identified by the Mann-Kendall test. It was found the statistically significant positive trends in air temperatures are generated during the summer season. The trend of maximum flow is offset in time from the calculated "winter" interval (1961-1981) to the calculated interval of "early snow melt flood" (1982-2010). Since 1989, a statistically significant increase in the maximum flow has been detected in the intervals of "late snow melt flood" and "spring floods". These shifts in time are due to changes in precipitation. The impact of rainfall on the generation of maximum flow is growing.

(university of el oued/جامعة الوادي, 2018-09-01) Kheniche, A; Ourari, A; Dakhouche, A; Ghanem, A; Meguellati, K; Min, W
The effect of three tetrahydroxylated Schiff bases as N,N-bis(2,3-dihydroxybenzylidene)-4,4’-diphenylmethane, N,N-bis(2,4-dihydroxybenzyl- idene)-4,4’-diphenylmethane and N,N-bis(2,4-dihydroxybenzylidene)-4,4’-diphenylmethane were studied as inhibitors for mild steel in 1M HCl medium. The experiments were performed using potentiodynamic polarization. This inhibition proved an efficient increase according the position of second hydroxyl of salicylaldehyde suggesting that this inhibition is dependent on concentration and the compound nature. Among these position-isomers, the best inhibition efficiency was obtained with p-hydroxylated (94%) at 1mM. Tafel plots of these inhibitors are the mixedtype, their adsorption is spontaneous obeying to Langmuir’s isotherm. AFM/SEM-EDS characterized metal surface. DFT-calculations and molecular dynamics simulations are correlated to inhibition efficiency obtained.
SIMPLE APPROACH TO GROUNDWATER STUDY FOR DOMESTIC USES IN RURAL AREA
(university of el oued/جامعة الوادي, 2018-09-01) Adagunodo, T. A
Nigeria is one of the countries facing challenges associated with water supply. In rural areas, majority depend solely on hand-dug wells for their consumption which are prone to contamination. This study is aimed to determine the potability of hand-dug wells in Eyenkorin using the geophysical and physicochemical techniques. Ten Vertical Electrical Sounding (VES) data were acquired beside ten dug wells that were used for the physicochemical analysis, with half-current electrode spacing (AB/2) which varied from 46 to 75 m. The VES results revealed that water from the wells were tapped at shallow aquifers, while the hydro-physicochemical parameters revealed higher constituents of TDS, Fe2+,, K+ and NO3- in the analyzed samples. It is concluded that the contamination in the study area is as a result of anthropogenic and geogenic contributions. Water treatment is recommended in the study area prior to domestic usage.
