Abstract:
Six isolates (VR1-VR6) of
Bradyrhizobium sp. from Vigna mungo were evaluated
for their plant growth promoting (PGP) attributes and antifungal
properties in vitro. All the isolates
produced IAA but none of them produced HCN. Isolates VR1 and VR2
produced siderophore, and enzymes chitinase and ACC
deaminase besides phosphate solubilisation and
antagonism against M. phaseolina. Cell-free
culture filtrates of Bradyrhizobium
strains VR2 resulted in maximum growth
inhibition of pathogen in dual culture causing several
deformities in hyphae and sclerotia such as
fragmentation, shrinkage and lysis of hyphae, cytoplasm
vacuolation, loss of mycelial pigment,
and inability of sclerotia formation and
germination. However, complete inhibition in mycelial dry
weight and sclerotia germination of pathogen was recorded at 45%
concentration of culture filtrates of strain VR2. Moreover,
patterns of sclerotia germination varied with
concentration of culture filtrates of VR1 and VR2. The number of
hyphae produced per sclerotium was more in control than the
culture filtrate-amended plates. The number of sclerotia
producing less hyphae got increased with increasing the
concentration of culture filtrate of strains VR1 than VR2. These
results suggest that the presence of inhibitory properties in
culture filtrates of Bradyrhizobium
strains help to act as potential
biocontrol agent for control of M. phaseolina.

Abstract:
Electrical resistivity
investigation was carried out around Bomo area, Kaduna state,
Nigeria in order to study the subsurface geologic layer with a
view of determining the depth to the bedrock and thickness of
the geologic layers. Vertical Electrical Sounding (VES) using
Schlumberger array was carried out at fifteen (15) VES stations.
ABEM terrameter (SAS 300) was used for the data acquisition. The
field data obtained have been analysed using computer software (IPI2win)
which gives an automatic interpretation of the apparent
resistivity. The VES results revealed heterogeneous nature of
the subsurface geological sequence. The geologic sequence
beneath the study area is composed of hard pan top soil (clayey
and sandy-lateritic), weathered layer, partly weathered or
fractured basement and fresh basement. The resistivity value for
the topsoil layer varies from 40Ωm to 450Ωm with
thickness ranging from 1.25 to 7.5 m. The weathered basement has
resistivity values ranging from 50Ωm to 593Ωm and
thickness of between 1.37 to 20.1 m. The fractured basement has
resistivity values ranging from 218Ωm to 520Ωm and
thickness of between 12.9 to 26.3 m. The fresh basement
(bedrock) has resistivity values ranging from 1215Ωm to
2150Ωm with infinite depth. However, the depth from the
earth’s surface to the bedrock surface varies between 2.63 to
34.99 m. The study further stressed the importance of the
findings in civil engineering structures and groundwater
prospecting.

Abstract:
Efficient
utilization of energy is of paramount importance for economic
and social development of a nation. A nation cannot develop
beyond her energy generation capacity. Power generation from
animal biomass is considered one of the best alternatives to the
growing issue of poultry litter management. This work,
therefore, investigated the products of thermo-chemical
conversion of poultry litter to medium grade-fuels and chemical
preservatives. A pyrolysis chain that consists of brick furnace,
condensate receiver, retort and gas collection unit was
developed and used for the experimental aspect of this work. The
moisture content of poultry litter was determined, while the
weight of pieces of wood used for pyrolysis was measured and
recorded. Oven-dried sample of poultry litter was heated up in
the furnace chamber. The products collected were weighed and
recorded. The pyrolytic gas collected was taken to laboratory
for further chemical analysis in other to establish constituents
of the gases. It took 35 minutes for complete pyrolysis to take
place.
The products
of the pyrolysis expressed in percentage of the oven-dried
weight of feedstock were 42.56% char, 38.76% mixture of
pyrolytic oil / pyroligneous acid and 18.68% of pyrolytic gas.
The pyrolytic gas was further analyzed and it contained 74.78%
of carbon, 25.22% of hydrogen. The pyrogas produced was found to
contain 20.17% by volume of methane
(CH4), 32.50% by volume of ethyne (C2H2),
21.82% by volume of ethane (C2H8),
and 10.88% by volume of carbon monoxide CO.
The study
concluded that, poultry litter lent itself easily to process of
pyrolysis and the products obtained could be used for domestic
and industrial cottage applications.

Abstract:
Reading, like any other activities, needs to be done properly. Talents, abilities and knowledge rely on the quality and the
length of reading to develop and blossom. The present study was
conducted to investigate the influence of systematic reading on
the students' academic progress in Jahrom Payam-e-Noor
University. 30 male and 30 female students of educational
sciences with average scores ranging from 12-15 (out of 20) were
selected randomly and separately and were placed in 4
experimental and control groups and using the experimental
method, systematic reading methods were performed for them. The
results showed the systematic reading method had a significant
influence on their learning. Also, the mean difference in
learning between males and females was random, which means the
influence is the same for both males and females.

Abstract:
The potential of
biopolymer chitin for phenol adsorption from aqueous solution
was studied. Batch kinetic and isotherm studies were carried out
under varying experimental conditions of pH values, contact
time, adsorbent dosage, phenol concentration, and temperature.
The adsorption of phenol decreased with increasing pH. The
Freundlich, Langmuir and Redlich-Peterson isotherm adsorption
models were used for the mathematical description of adsorption
equilibrium and it was found that the experimental data fitted
very well to the Langmuir model. Batch adsorption models, based
on the assumption of the pseudo-first-order pseudo-second-order
and intra-particle models, were applied to examine the kinetics
of the adsorption. The results showed that kinetic data followed
closely to the pseudo-second-order model.

ABSTRACT:
Recent evidence has
linked low plasma folic acid and vitamin B12
concentrations with endothelial dysfunction, often found in type
2 diabetes mellitus. But no available study has associated
decreased level of essential fatty acid with type 2 diabetes
mellitus in Nigerians.
This study was designed to
evaluate plasma levels of essential fatty acids, folic acid and
vitamin B12 in type 2 diabetes mellitus patients.
Sixty eight type 2 diabetes mellitus patients with a mean age of
63.48 ± 10.91 years were recruited. Twenty six apparently
healthy volunteers with a mean age of 38.32 ± 12.26 years were
included as controls. Anthropometric indices and biochemical
parameters were determined using standard techniques.
The results showed
significant decreases in plasma linoleic acid, arachidonic acid,
folic acid and vitamin B12 (p < 0.05) compared with
the control values. On the other hand, there were significant
increases in fasting plasma glucose, body mass index (p < 0.001)
and waist circumference (p < 0.05) compared with the control
values. Significant correlation was obtained between arachidonic acid and folic acid levels (p < 0.05). The main
findings from this study were decreased plasma linoleic acid,
arachidonic acid, and folic acid and vitamin B12 in
association with increased WC and BMI in
type 2 diabetic patients. Thus providing evidence that decreased
levels of essential fatty acids, folic acid and vitamin B12
are associated with type 2 diabetes mellitus in Nigerians.

ABSTRACT:
The molluscicidal activities of aqueous and ethanolic extracts
of Cymbopogon citratus
leaf against adult, juveniles and egg-masses of
Biomphalaria pfeifferi were investigated. Ten adults each
of Biomphalaria pfeifferi were exposed to a serial
dilution of 40, 80, 160, 240, 320, 400, and 480ppm distilled
water extracts and 20, 40, 80, 160, 240, 320ppm ethanolic
extracts. Twenty juveniles of uniform size each were exposed to
8, 20, 28, 40, 80, 120, and 160ppm of aqueous and ethanolic
extracts. Thirty eggs each were exposed to 8, 20, 28, 40, 60,
80, and 100ppm of aqueous and ethanolic extracts. Exposure
period was 24hrs for adult and juvenile stage while 48 hrs for
the egg stage. The lethal concentration LC50 against
eggs, juveniles and adults were 73.27, 64.60 and 140.74ppm
respectively for Cymbopogon
citratus aqueous extract, 42.85, 43.87 and 61.79ppm
respectively for Cymbopogon
citratus ethanolic extract. The lethal concentration
LC90 against eggs, juveniles and adults were 182.37,
244.42 and 254.92ppm respectively for
Cymbopogon citratus
aqueous extract, 113.20, 166.31 and 159.47ppm
respectively for Cymbopogon
citratus ethanolic extract. The plant extracts caused
significant mortality rates of the different stages of B.
pfeifferi (P<0.05). The result obtained show that
Cymbopogon citratus
is a promising plant molluscicide candidate and deserves
further studies in order to identify and characterize its
molluscicidal components.

Effect of Hydrophilic Polymer
on wetting dimensions, under drip irrigation
Mohammad Habibollahi, Abd
al-rahim Hooshmand
Department of Irrigation and
Drainage, Shahid Chamran University of Ahwaz, Iran
mhabibollahi2000@yahoo.com
In drip irrigation systems
design, wetting patterns is an important feature that should be
considered. The use of some materials such as hydrogels, in sand
soils, usually reduced hydraulic conductivity (HC), but in heavy
clay soil porosity will increased. The final swelling hydrogels
in soil is less than the free state. In this study, was
investigated effect of A200 super-absorbent on vertical wetting
depth under drip irrigation, including the four treatments
(control (0), 0.1, 0.2, and 0.3 wt %). the moisture front
advance was checked by IDRG SMS-T1 system. The investigation
showed that the use of drip irrigation with super absorbent for
4 liters per hour discharge, in loam soil, the soil wetting
front penetration depth has been reduced, and water accumulation
in the surface layer (layer modified by the super- absorbent)
increases. Experiments
were performed on four occasions. First up to third irrigation
was performed when soil moisture content had reached to neighbor
wilting point. But, soil moisture content in fourth irrigation
was limited to FC. Because
of this, depth of wetting front advance in treatment 0.3 percent
less than other treatments and was occurred significant
differences between control and treatment. The lowest depth was
seen in control and was occurred significant differences between
control and treatments 0.2 0.3 percent.

Abstract: The experiment was conducted at Dokki protected cultivation site, Agricultural Research Center, Giza, Egypt during 2010/2011 and 2011/2012 seasons. Four cantaloupe hybrids (Rafigal, Arafa, Primal and Gal 152) were sown on March 5th in both years. Volumetric lysimeter was installed, to estimate water requirements with three water levels of daily water levels at 80, 100, and 120% of Etc. In this respect, a split design with three replicats was implemented. The main plots contained the irrigation treatments and the sub plot included the four cantaloupe hybrids. Actual crop evapotranspiration (Etc) was determined by weighing lyismeter ±1 gm with two plants on its plate surface. Potential evapotranspiration (Eto), utilizing Penman Monteih equation. The effect of water stress, during the different growth stages was studied, in order to determine the optimum water requirements. Obtained results indicated that, the plant vegetative growth was enhanced with 100% (Etc) treatment, the tallest plant was found with Rafigal F1, the highest leaf number was found on Arafa F1, compared with the other two levels of irrigation. The water level at 100% (Etc) optimized total yield and fruit quality. While, the lowest total yield with first grade fruit quality was recorded with water level at 80% (Etc). But, water level at 120% (Etc) increased significantly total yield with decreasing fruit quality. The highest total yield was obtained by Arafa F1 hybrid. While, Primal F1 hybrid fruits had the highest values of total soluble solids, total sugars, fruit volume and firmness.

Abstract: Noodles popularity among the different age groups in the country, has made it important to access the fatty acid profile of three different brands of noodles in Nigeria. The oil from noodles was extracted using petroleum ether with a soxhlet apparatus. Their fatty acids profile was determined using a Gas chromatography equipped with a flame ionization detector (FID). A total of thirteen, fifteen and fourteen components were detected from samples A, B and C respectively. 120g of the noodles A, B and C yielded oil of 12.98%, 13.7% and 27.66% respectively. The fatty acids of highest percentage composition are Palmitic acid (36.8±0.1 to 42.6±0.1), Stearic acid (15.8±0.2 to 18.7±0.1) and Oleic acid (11.46±0.1 to 25.5±0.1) of the oil. Sample C had the highest composition of both total saturated fatty acids (TSFAs) and polyunsaturated fatty acids (PUFAs), but had the lowest monounsaturated fatty acids (MUFAs) and total unsaturated fatty acids (TUFAs). The consumption of sample C, having the highest oil yield, could lead to obesity; also, having the highest saturated fatty acid, makes it risky to human health when consumed regularly. The result of this study indicates that sample B contains the least stable oil among the three samples in terms of C18:2/C16:0. The stabilities of samples A and B in relation to C18:2/C16:0 were significantly not different.

Abstract: In mathematical programming it is customary to distinguish linear and convex programming. In nonlinear programming the objective function becomes nonlinear or one or more of the constraints inequalities have non-linear inequalities have non-linear relationship or both. Non-linear programming which has the problem of minimizing a convex objective function in the convex set of points is called convex programming where the constraints may taken to be non-linear.

Abstract: Meidavood, located in the northeastern part of Khuzestan, and one of the environs of Ramhormoz, is located between latitude 31° 10´ to 31° 25´ north and longitude 49° 10´ to 50° 10´ east. This region consists of two stratum water units : a) the Karsti unit consisting Asmari and Gachsaran formations, b) the alluvial unit or the Eidavood-Daloon plain. The underground water in unit b, feeds through precipitations and lateral seepage from the water leaking through leakages from adjacent formations and the water flows mostly from east to the west of the unit. In order to investigate the quality of the underground water in this region, water sampling was conducted by standard methods of EPA 2001. The results of the titrated measurement and flame photometry showed the main components of these bodies of water which, due to the dissolution of the Gachsaraan formation, the dominant facies is the calcium-phosphate. Also, the results of the ICO-OES analysis of the underground water showed that the concentration of Arsenic is more than the permissible global ones (10 bbp) in almost 81% of deep wells and the concentration of iron, manganese, nickel, and vanadium is high in those wells. The results of the XRE analysis of the surrounding geological formations and the aquifer sediments suggested that the original source of Arsenic can be attributed to the Asmari and Gachsaran formations. It seems that the key process responsible for the release of Arsenic in the Meidavd-Daloon alluvium aquifer deep wells is biological disintegration of organic materials associated with oil hydrocarbons. This process causes the dissolution of arsenic oxy-hydroxides of iron and manganese and, as a result, iron and nickel in organic materials enter underground water. Given the oxidation-reducing conditions, the Meidavood-Daloon alluvium aquifer can be categorized into 4 regions:1)partly reducing, medium- reducing, and highly - reducing. In this aquifer, the arsenic-contaminated wells are located in highly and medium reducing parts.
