This study deals with the effect of prescribed fire on some
driving and abiotic variables of protected and grazing sites at
Pauri. Ransi-Nagdev areas were selected for the present
investigation in which two were burned (protected and grazed)
and the other two sites were unburned (protected and grazed). In
this study data for rainfall, atmospheric temperature and
relative humidity were considered as driving variables, whereas
abiotic state variables are being represented by soil reaction,
soil physical and chemical properties. Maximum rainfall (229.0
mm) was recorded in August 2006 and minimum (18.0mm) in December
2006 and January 2007. The mean maximum temperature ranged
between 7.2 (January 2007) and 22.5 °C (June 2006). The relative
humidity at 0800 hrs was maximum (82.0%) in September, 2006 and
minimum (46.5%)in November, 2007, however, at 1630 hrs. it was
maximum (78.5%) in September, 2006 and minimum (39.5%) in
November, 2006. Across the sites, the mean soil temperature was
highest on MBG(burned grazed) and lowest in MUP(unburned
protected) during the year. The soil moisture percentage was
higher during rainy season in MBP(burned protected) (27.50) and
lower values were recorded during summer season in MBP (17.0).
Total nitrogen was maximum (188.50 gm ̄ ²)) during summer season
on MBG and minimum (133.15 gm ̄ ²)) in rainy season on
MUG(unburned grazed). The maximum value of exchangeable
phosphorus(151.15 kg ha ̄ ˡ)) in rainy season on MBP and Minimum
(41.50 kg ha ̄ ˡ)) during winter season on MUP. Exchangeable
potassium was maximum (268.50 kg ha ̄ ˡ)) in winter on MUG and
minimum (135.0 kg ha ̄ ˡ)) during summer on MUG.

Abstract: Acute bronchial asthma is characterized by acute
episodes of obstruction relateded to airway inflammation mostly
in response to respiratory tract infection. CD14 play a key role
in inflammatory pathways. The aim of this study is to determine
the influence of CD14 gene polymorphism and its plasma levels on
the predisposition to develop asthma and its severity. This
study was conducted on 20 patients during acute attack of asthma
(group I) and in convalescence (after 6 weeks of treatment of
the same patients, group II). Asthma severity scoring system was
preformed to all patients according to (Martin et al; 2006).
Arterial blood gases, plasma levels of sCD14 and
serum total IgE were measured by ELISA. CD14 gene
polymorphism was detected by restriction fragment polymorphism (PCR).
During acute asthma,
plasma levels of sCD14 were higher than during
convalescence: sCD14, 3.23±0.48 versus 2.64±0.24 µg/ml, (p=
0.001). Higher plasma levels
of sCD14 were
present during the acute attack in those with 159TT
and 159TC (p= 0.002 & p= 0.001, respectively), whereas in
159CC homozygous, sCD14
levels were insignificantly increase during the acute
attacks (p= 0.119). A significant negative correlation was found
between sCD14 and asthma score (r= 00.58, p= 0.001). There was a
significant positive correlation between IgE and plasma level of
sCD14. These results suggest
that in acute
sCD14 is increased in an
attempt to control airway inflammation, and for subjects
whose genotype limits or prevents these increases, the
ability to control airway inflammation is impaired
resulting in more severe

Succulent plants are good sources of bioactive materials such
as saponins, flavonoids, coumarins, alkaloids, anthraquinones,
tannins, cardiac glycosides and steroids etc.,. These bioactive
materials gave these plants their medicinal importance regarding
treatments of many dangerous diseases such as cancer, diseases
that caused by bacterial infections and oxidative stress.
Different parts of shoot systems of six succulent plants;
Carpobrotus edulis, Rumex vesicarius, Zygophyllum
coccineum, Hammada elegans, Anabasis articulata
and Anabasis setiferae were studied regarding their
chemical constituents. Phytochemical screening on different
plant parts of these succulent plants revealed variations in
phytochemicals under investigation within different plant parts
of these plants.

Galvanized Steel -Stainless Steel Spot welded joint Using
Inserted Pin Technique
M.A. Morsy*, A.A
Sadek and E. Rabea
Resistance spot welding of galvanized steel to stainless steel
was conducted using inserted pin technique. In this technique,
the galvanized steel sheet was drilled and a stainless steel pin
of 2 or 4 mm diameter was pushed into the drilled hole. The
resistance spot welding was conducted between the galvanized
steel inserted-pin sheet and the stainless steel sheet. The
performance of the joint welded using inserted pin technique was
evaluated and compared with that of the normal resistance
welding technique at different levels of welding time, welding
current and welding pressure. The joints welded using 2mm
inserted pin technique show higher fracture load than that
welded by normal one. On the other hand, joints welded using 4
mm inserted pin show lower fracture load compared with normal
technique. This may be attributed to the decrease in the
circumferential fused area around the pin between the stainless
steel and the galvanized steel. Hardness of weld metal is very
close to that of stainless steel HAZ, However, the hardness of
the galvanized steel HAZ is much higher than that of the base
metal. The results was discussed on the basis of microstructure,
heat generated and fracture load of welded joint.

This work was
carried out for biosynthesis of specific bioactive substances
that demonstrated inhibitory effects against pathogenic
microorganisms from Streptomyces cyaneus, AZ-13Zc. The
active metabolite was extracted using ethyl acetate (1:1, v/v)
at pH 7.0. The separation of the active ingredient and its
purification was performed using both thin layer chromatography
(TLC) and column chromatography (CC) techniques. The physico-chemical
characteristics of the purified antimicrobial agent have been
investigated. This analysis indicates a suggested imperical
formula of C36H59NO12. The
minimum inhibition concentrations "MICs" of the purified
antimicrobial agent were also determined. The purified
antimicrobial agent was suggestive of being belonging to
16-membered Macrolide group (Cirramycin-B antibiotic) produced
by Streptomyces cyaneus, AZ-13Zc.

are one of the most promising technologies of distributed
computing. Mobile Agents have certain properties, such as
autonomy, mobility and most of all; they fit well in the
low-bandwidth network environments. This paper mainly focuses on
the information retrieval in a distributed computing environment
using a Mobile Agent. This approach is materialized by a UML
notation, which includes views to model organizational,
lifecycle, interaction and mobility aspects of mobile agents’
applications contributing to the analysis, design and
implementation phases of their development. The PHP programming
language is used for the implementation part using the PHP-YAZ
and the Z39.50 protocol.

presents the potential utilization of Rubber Seed Oil (RSO) as a
base oil for the production of alkyd resin using a nine sample
oil lengths of 40,50 and 60%. The basic feed stocks for the
production of the alkyd resin are RSO; Pthalic anhydride and
Glycerol reacted at different stipulated ratios. The methodology
employed is the experimental frame works and procedures
developed by Rubber Research Institute of Nigeria (RRIN), Iyama,
Benin City, Project Research and Development Institute (PRODA),
Enugu and America Standard for testing of Materials (ASTM), USA.
The parameters tested for both the RSO and produce alkyd resin
include: Colour, specific gravity, viscosity, smoke point, flash
point, saponification value, acid value and iodine value.
Experimental results show that the acid value, iodine value and
saponification value range from 8.08 to 10.60mgNaOH/g oil, 46.4
to 86.18 gI2/100g oil; and 389.90 to 531.08mg NaOH/g
fat, respectively. It can be concluded that the 60% of oil
length is of the best drying qualities in terms of tack free
conditions with respective to the oil investigated and at the
conditions of the experiment.

Field experiment was conducted on the adaptability of bambara
groundnut in humid rain forest tropical zones with six local
accesssions in a Randomized Complete Block Design with three
replications. Data was collected on the yield and yield
attributes, and analysed with analysis of variance (ANOVA) and
means separated by least significant difference (LSD p=0.05).
Correlation studies were carried out to determine the
relationship between yield and yield attributes. Results of
analysis of variance showed significant differences in plant
height, canopy diameter and petiole length, and no significant
differences in number of stems and dry matter weight (biomass)
among accessions. Correlation analysis between yield attributes
and fresh pod weight indicated positive correlation in all
cases. However, plant height and number of stems had a near
perfect positive correlation signifying that the higher the
height of the plant the greater the yield. The performance
ranking of the accessions showed that AC-01 had the best overall
performance while AC-05 had the least. Conclusively, bambara
groundnut is apparently adaptive in the study area (especially
tall growing accessions), and can contribute immensely in food
and nutritional security in this agroecological zone.

The African invader fly Bactrocera invadens Drew, Tsuruta and
White, generally considered as the most devastating pest of
mango was detected in Africa (in Kenya, East Africa) in 2003. It
was first detected in Ghana, West Africa in 2005. The perception
of mango farmers from Dangbe West and Yilo Krobo districts in
Ghana on the pest status and the current management options
adopted for the control of this pest was sought by use of a
Questionnaire. The survey results indicated that Ghanaian
farmers rank B. invadens among the major pests of mango in
Ghana. Farmers generally, believed that it is more damaging than
other arthropod pest of mango. Possible losses such as loss of
market value, rejection of produce at the international markets
and quarantine restriction due to the presence of the pest were
also reported by the farmers Several strategies are being
adopted by farmers for the control of fruit flies (including
B.invadens) in Ghana. These strategies include the use of
insecticides, cultural control measures, and use of trappings to
manage fruit flies. Some of the respondents use a combination of
insecticides and cultural practices to reduce the menace of
fruit flies. It was evident that farmers adopt multiple
strategies to minimize the loses due to fruit flies in an IPM

The use of
activated clay and coal as adsorbents in the removal of three
different colors of dyes (acidic orange dye, D1, basic yellow
dye, D2 dispersed blue dye D3) from aqueous media is studied.
The study involved the continuous fixed bed and batch adsorption
process employed for the determination of breakthrough times and
adsorption constants (Freundlich and Langmuir) respectively. For
the activated coal in fixed bed the breakthrough time were 20
mins and 25 mins for D1, D2 and D3, respectively. For activated
clay, the break through time were 20 mins and 25 mins for D1,D2
and D3 respectively. The experimental equilibrium data obtained
for coal and clay fit better in the Freundlich and Langmuir
adsorption isotherms, respectively at the conditions of the
experiment. It can be concluded that if will processed, clay and
coal are potential sources of adsorbing materials.

Exotoxin (Streptolysin O) Removal from Water Using Ozone Gas
Roushdy M. Mohamed

concentrations of bacterial toxins could occur as a result of
contamination of open water. The object of this paper was
focused on the inactivation of bacterial toxin (streptolysin O)
in water by ozonation process. The interest in ozone as a water
disinfectant is based on its high biocidal efficacy, wide
antimicrobial spectrum, absence of by-products that are
detrimental to health and the ability to generate it on demand,
''in situ'', without needing to store it for later use.
The efficacy of ozone for bacterial toxin inactivation increased
with increasing exposure time (5 minutes) and ozone
concentration (7 g/m3). A bacterial strain (streptococcus
pyogenes ATCC 19615) was allowed to grow on toxin production
medium. Subsequent extraction and precipitation of toxin was
conducted for detection of toxin. Finally the crude toxin was
treated with ozone gas. The ozone was generated using coaxial
dielectric-barrier-discharge (DBD) technique. In the present
work, the cell of the discharge consists of coaxial electrodes.
Ozone was applied directly into the tubes containing 1 ml of the
crude SLO diluted with PBS at pH 7.4.
