Title:

Testing efficiency of pseudomonas aurgiuos and staphylococcus aures bacteria in reducing the concentrations of glyaphosphin and toluene used as fueland fertilizer

Author (s):

Raad Abdul Hadi Nayyef

Abstract:

The aim of the research was to use efficient bacterial isolates to reduce the concentration of these substances Toluene and Glyphosphets to minimize their effects. These models were placed in special irrigated mediums in addition to efficient bacterial isolates. The efficiency of these isolates was determined depending on the growth in terms of absorbance at 600nm wavelengths. (0.01, 0.02, 0.03) concentrations for both substances, Staphylococcus aures, Pseudomonas aurginosa, were also used for the treatment. It was found that P. aunginosa has a high removal rate at the three concentrations (0.01, 0.02, 0.03) of Toluene and Glyphosphets. while S. aures showed high removal of the Toluene at concentration (0.01) compared to concentrations (0.02 and 0.03). Therefore that P. aurginosa has removal at the two constriction (0.02, 0.01) Ml 3 cm while on (0.03) ml constriction 2.5 cm. The removal for Glyphosphets Material (3) cm on (0.01) ml concentration and (3) cm of (0.02, 0.03) ml concentration and the removal rate of S. auresfor both substances (1.5) cm on (0.01) concentration and (1) cm on (0.02) ml concentration while the removal (0.5) cm o (0.03) ml concentration. It was concluded that Pseudomonas aurginosa is highly efficient in reducing the concentrations of both Toluene and Glyphosphets compared with Staphylococcus aures.

Title:

The surface water storage problem in arid regions: A case study of the gargar dam, Algeria

Author (s):

Hassen Benfetta and Abid Ouadja

Abstract:

Most dams lose capacity as a result of three principal phenomena: leakage, sedimentation and evaporation. The study of these phenomena is particularly important as they can also endanger the damís stability. Here, we examine the case of the Gargar dam in western Algeria. This dam is located in an arid zone where water resources are becoming increasingly scarce. It is situated 5 km from the city of Ghelizane and is subject to considerable water loss. It has never been filled to capacity, and is now threatened by leakages that are clearly evolving over time. This article extends our earlier studies of the dam. Our work has estimated total average losses of 25 million m3 /year for the period 1988Ė2015, made up of leakage (0.3 million m3 /year) and evaporation (18 million m3 /year), while dead storage accounts for 4.6 million m3 /year. However, total losses for 2004 were estimated at 113.9 million m3, which increased to the alarming value of 166.8 million m3 in 2015. We analyze variation in leakage as a function of the reservoir level, and quantify losses due to leaks, sedimentation and evaporation.

Title:

Abstract:

The effect of residues was studied (palm, peanut, tea) in the characteristics of vegetative growth and the bulb onion in addition to the total yield OF onion plant (Allium cepa L) in El Oued zone (Algeria) during in 2016 season. An investigation was a randomized complete block design in three replications. The obtained results of experiment showed that: response the onion plant Application of fertilize by cooked tea leaves, were significantly better in of the studied characters (plants height and Leaves Area) with rate increased to 47.15% and 93.4% respectively, than control treatment. Followed by T1 and then T3. Peanut Peels treatment gave the largest number of tubular blades in the plant (12.33), the diameter of the bulb neck (13.48mm) and bulb Length (7.35cm) than other treatments. Followed by T2 and then T3. Cooked tea leaves plants gave highest diameter of bulb (5.42cm), highest bulb weight (66g) and yield (20.85 t/ha) in the season. Where Achieving with T1 (18.35t/ha) significantly increase in the yield total in comparison with other treatments.
