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: |

problem in arid regions: A case study of the gargar dam,
Algeria |

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 dam’s
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 1988–2015, 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. |

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. |
