Abstract: The present study focused on the hydrochemistry of groundwater in
Jaipur city to assess the quality of groundwater for
determining its suitability for drinking and agricultural
purposes. Groundwater samples were collected from eleven
stations of Jaipur city during monsoon season and were analyzed
for physico-chemical parameters such as pH, EC, TDS, sodium, potassium, calcium,
magnesium, chloride, sulphate, carbonate, bicarbonate, nitrate
and fluoride. Comparison of the concentration of the chemical
constituents with WHO (world health organization) drinking
water standards of 1983, the status of groundwater is better
for drinking purposes. Results indicate that nitrate
concentrations are in an alarming state with respect to the use
of groundwater for drinking purposes. The calculated values of
SAR, RSC and
percentage sodium indicate that the water for irrigation uses
is excellent to good quality. US
Salinity diagram was used for evaluating the water quality for
irrigation which suggests that the majority of the groundwater
samples were good for irrigation. [Nature and Science

Comparative efficiencies of the
degradation of C.I. Mordant Orange 1 using UV/H2O2, Fenton, and
photo-Fenton processes

Science, Al-Azhar University (Girls), Nasr City, Cairo, Egypt.
Abstract: The kinetics of the photo degradation
of C.I. Mordant Orange 1 imparted by UV/H2O2,
Fenton and photo Fenton process were investigated. Negligible
effects were observed in the presence of either UV light or H2O2
alone. As expected the Fenton-mediated degradation occurred much
faster than the photolytic process. Photo Fenton showed higher
in treatment efficiency than that of Fenton process. The
effects of dye concentrations, H2O2
concentration, pH values and the presence of Fe2+
concentration on the degradation rate constant were also
studied. The rate constant of dye degradation that occurred in
both the phtolytic as well as in the Fenton and photo-Fenton
processes was found to pseudo first-order kinetics. [Nature and

Abstract: The need to
clean-up heavy metal contaminated environment cannot be over
emphasized. This paper has been studied the distribution
coefficients of Ce(IV), Al(III), Fe(III), Bi(III), Ca(II),
Ba(II) and Pb(II) on cation exchange resin Purolite C100 in the
presence of some chelating agent at 25°C. Sodium nitrate,
citric acid and ethylene diamine tetraacetic acid (EDTA) were
tested as eluants. The relative efficiency of the eluants has
been discussed in terms of their elution constants. A rapid
ion-exchange method was proposed for the separation of lead
cations. The method has depended on the selective complexing of
metal ions by a chelating agent as achieved by control of pH.
Several binary separations of metal ions have been achieved on
the basis of their kd values. [Nature and

Abstract: The
effects of 10% dried mushroom and 300 mg mushroom extract on
the lipids profile, lipid peroxidation and liver functions of
rats were evaluated and compared with L-carnitine. Food intake,
body weight and histological examination of liver tissues were
also evaluated. Supplementation diet of rats with 10% dried
mushroom, 300 mg mushroom extract and 300 and 600 mg
L-carnitine resulted in a significant decrease in total lipids,
triglycerides, total cholesterol, low-density lipoprotein, very
low-density lipoprotein, aspartate amino transferase (AST)
enzyme, alanine amino transferase (ALT) enzyme, alkaline
phosphatase (AP) enzyme, malonaldehyde (MAD) and body weight
compared to control. However, glutathione peroxidase enzyme
(GSH) and food intake were significantly increased in rats
supplemented with 10% dried mushroom, 300 mg mushroom extract and
300 and 600 mg L-carnitine. Liver tissues of rats were improved
by the supplementation with 10% dried mushroom and 300 mg
L-carnitine. However, the supplementation with 300 mg mushroom
extract and 600 mg L-carnitine were more effective in improving
the liver tissues. These results suggest that mushroom and
their extract can be improve the antioxidant status during
ageing and minimize the occurrence of age-associated disorders
associated with involvement of free radicals. [Nature and

Abstract: A laboratory experiment was conducted
in the algae-station of the Fertilization Technology
Department, National Research Centre, Dokki,
Cairo, Egypt
with the green alga Scenedesmus
sp. to study the effect of citrate waste in the nutrient
solution on vegetative growth and pigments accumulation. The
alga was incubated in 2000 ml culture with 10 ml citric acid
waste characterized by high CNPK contents. After maximum growth
rate was achieved induction was performed (by the day ten) and
separate addition of NaCl, FeSO4 and chelated FeSO4
was performed and citrate volume was raised to be 50ml.l-1.
Growth measurements were dry weight, total chlorophyll and
carotenoids. Results showed that maximum vegetative growth was
reached after approximately 10 days of incubation. The maximum
growth rate during this period was 0.29 and 0.26d-1,
while average growth rate was 0.14 and 0.16d-1for
dry weight and total chlorophyll, respectively. Except of
cultures received chelated FeSO4, all other treated
cultures (control, metal FeSO4 and NaCl) resulted in
complete degradation of chlorophyll and carotenoids massive
accumulation. The cultures were completely greenish yellow and
yellow colored. Maximum chlorophyll ratio was found in control
cultures which received citrate only (50ml.l-1),
however maximum carotenoids ratio was detected in the algae
supplied with metal FeSO4, followed by 2% NaCl.

*Email: nsheorankuk@yahoo.com
Abstract: An
efficient regeneration protocol under in vitro conditions has been developed for Sapindus mukorossi
Gaertn.- an important medicinal plant using nodal segments.
Nodal explants of this species were cultured on Murashige and
Skoog medium supplemented with various concentrations of auxins
and cytokinins individually and in various combinations. BAP
was found to be more effective than Kinetin for shoot
multiplication. The highest number of shoots (2.0 ± 0.29) was
achieved on MS medium augmented with 2.0 mg/l BAP. The medium
supplemented with 2.0 mg/l
BAP + 1.0 mg/l NAA responded better than all other media
combinations. MS half strength medium supplemented with 2.0
mg/l IBA proved better with forty percent rooting after 22 days
of implantation. Most of the roots were long and healthy. The
micropropagated plantlets were hardened and acclimatized. They
were successfully transferred in pots containing sterilized
soil and sand mixture (1:1) with 60% survival rate under field
conditions. [Nature and Science 2010;8(10):41-47].

Abstract: Background and Objective: There has
been a growing concern of the potential health hazards imposed
by use of dental filling materials that include toxic
compounds. So this study was designed to evaluate the percentage
of apoptotic cells in the epithelium of buccal and labial
mucosa after applying amalgam and composite filling materials.
Materials and Methods: The
epithelial cells were stained with fluorescence dyes; ethidium
bromide, propidium iodide and monoclonal antiFas-1 antibody
then examined under fluorescent microscope. Results: The
cytotoxicity of amalgam was decreased with aging time while
that of composite was increased. On the other hand, using
antifas-1 antibody, it was found that the apoptotic cells were
died through mitochondrial pathway. [Nature and Science

Abstract: Background and Objective: There is a
definite correlation between the dermatoglyphic patterns and
the oral cleft deformity. So the aim of this study was to detect
the correlation between dermatoglyphics and the number of
apoptotic cells that induced by dental fillings. Materials and
Methods: Finger and palm prints were collected from 32 patients
with dental caries who replaced it with amalgam and composite
fillings then compared with 15 normal persons. Results: The patients with lower
number of apoptotic cells were characterized by increasing
whorl patterns on the finger-tips. Meanwhile, the ulnar loop
pattern was the dominant pattern in the patients with moderate
and higher number of apoptotic cells. Conclusion: The variation in the
dermatoglyphic patterns according to the number of apoptotic
cells in one week group indicates genetically susceptible and
resistant patients to filling toxicity. [Nature and Science

Abstract: Among its neighboring countries,
Egypt had its higher rates of HCV infection. The relation
between bilharzial co-infection and the progression of
hepatitis, in HCV-infected patients, was studied in this work.
55 liver biopsies from 55 HCV-infected patients, with and
without bilharzial co-infection, were used. Histopathologically,
characteristic but not diagnostic histopathologic features of
chronic HCV infection were revealed. 5 hepatocellular carcinoma
(HCC) cases, with different grades of differentiation, were
detected. Bilharzial co-infection was accompanied by the more
progressive changes. Depending on METAVIR, 39 cases were
classified at stages 0:3 of fibrosis, whereas 11 were at stage
4 (=cirrhosis). Collagen fibers continued to increase with the
progression of the disease. Immunohistochemically, AFP
was diagnostic in 80% of hepatocellular carcinoma (HCC),
whereas only three (3/39=7.5%) cases of stages 0:3 of fibrosis
were positive. Using DNA image analysis, most of cases
(44/55=80%) were diploid and the rest (11/55=20%) were
aneuploid, with high SPFs. Among the aneuploid HCC cases, one
of the 3 well differentiated was tetraploid and the poorly
differentiated one was multiploid; presenting a higher frequency
of DNA abnormal population. Interestingly, both the two
aneuploid cirrhotics and the tetraploid well differentiated HCC
were belonged to patients with bilharzial co-infection. [Nature

*Kbaderkhan@yahoo.com
Abstract: Cytogenetic
evaluations of pyrethroid insecticide cyhalothrin (lambda) were
investigated in mice in vivo by recording chromosomal
aberrations in bone marrow cells and in primary spermatocytes.
Cyhalothrin (lambda) insecticide was orally administrated with
2, 2.5, 5 mg/kg b.wt. (1
∕10, 1 ∕8, 1 ∕4 LD50 doses respectively) for
repeated treatment. Cyhalothrin (lambda) was found to produce a
significant structural and numerical chromosomal damage after
subacute treatment in both bone marrow cells and primary
spermatocytes. This effect was dose and time-dependent. For
studying sperm abnormalities, mice were orally treated with the
highest dose, 1 ∕4 LD50. Cyhalothrin (lambda) insecticide
was found to induce a significant increase in the percentage of
sperm abnormalities which was mainly in the head. The present
study clearly indicates that Cyhalothrin (lambda) insecticide
is genotoxic to the different kinds of cells analyzed. [Nature and Science

Author: - R.
MANJUNATH (manjunath5496@gmail.com)
Abstract: - Photons, like all
elementary particles, exhibit both wave –like and
particle like properties .The dual nature of photons can be
visualized through their interaction with other objects. The
photons possess momentum; carry mass during its motion. Hence
they also exert force and pressure on other objects. The recent
astronomical observations stated that the radiation pressure is
strong enough to push an asteroid. This statement shocked the
scientific comity and made them to gape in an astonished way,
thinking that do radiation pressure really pushes an asteroid.
The inherent goal of proposal of this mathematical model is to
calculate the force exerted by the photon on the other
elementary particles, in a simple and consistent way. The basic
concepts of quantum mechanics and classical mechanics are
incorporated together in a single frame work to lay the
foundation for the emergence of the equation for the
calculation of the force imparted by the photon on other
elementary particles like proton, electron etc. [Nature and

ABSTRACT: Trypanosome
infection might affect grasscutter’s productivity while
in domestication. The PCV, MCHC, total WBC and Lymphocytes of
the grasscutters experimentally infected with T. congolense and T. vivax decreased
(p<0.05), while MCV increased (p<0.05) 21dpi. Plasma glucose
and cholesterol were decreased (p<0.05). Body temperature
fluctuated between 37.40C and 39.20C with
a peak on day 12 (39.20C) in T. congolense and 37.50C to 40.10C
which peaked on day 8 (40.10C) in T. vivax. The livers and
kidneys showed vacuolar and tubular epithelial degeneration
respectively, with thrombosis in alveolar blood vessels. It was
concluded that the grasscutter may serve and might have been
playing the role of reservoirs hosts for this economically
important disease. Infected grasscutters though did not show
clinical signs of this disease, but clearly manifested
haematological and tissue changes which could lead to
death. [Nature and

Abstract: The study was
carried out in order to investigate the change in soil
temperature and evaporation under undulation surface conditions
(C+ site, 50cm high from the reference level C site, and C-
site, 50cm low from reference level C site, respectively) which
were treated for determine the reason for the difference in the
soil temperature and the evaporation in saline soil. The
results indicated the fluctuation of soil temperature was more
dynamic in surface than the deeper layers and decreased with
depths for all of treatments. The average difference in maximum
surface temperature was 5.4℃ lower in the
C- site than the C site, 1.0℃ higher in the
C+ site than in the C site during a day (28 August 2009). The
average evaporation was 41.4% to 94.1% higher in the C- site
than in the C site and the C+ site during observations (from 27
August to 4 September, 2009). The average thermal conductivity
was 0.29 W/m℃ larger in the
C- site than the C site, 0.02 W/m℃ lower in the
C+ site than in the C site. Analysis of variation showed there
was significant (p<0.05) difference in soil temperature and
evaporation due to the difference in soil water content
affected by the undulation soil surface. [Nature and

Science, Ain Shams University, Cairo, Egypt
Abstract: Sixty food samples were collected
from 60 random restaurants of fast and traditional fast foods
in El Qassium, Saudi Arabia and investigated for bacteria species
using different temperatures (10oC, 20oC,
30oC, 40oC and 50oC) incubated
for 24-48 hours and analyzed for fungi and yeasts incubated at
25oC. The results revealed that from 45 sample of
traditional foods, yielded a total twenty two species of eighteen
genera of bacteria. A fourteen species of twelve genera of
fungi and three species of three genera of yeasts. While fast food results revealed
that from 15 fast food samples collected from 15 restaurants a
total ten species of ten genera of bacteria. A total eight
species of seven genera of fungi. The species of bacteria
isolated in this study namely, Acetobacter sp., Achromobacter
sp., Bacillus coagulans, B. Subtilis, Clostridium perfringens,
Erwinia carotovora, Escherichia coli, Flavobacterium sp., Klebsiella
pneumoniae, Lactobacillus plantarum, Leuconostoc mesenteroides,
Listeria monocytogenes, Microbacterium lacticum, Micrococcus
sp., Pseudomonas aeruginosa, Pseudomonas fluorescens,
Pseudomonas putrefaciens, Salmonella sp., Staphylococcus
aureus, Streptococcus lactis, Streptococcus thermophilus,
Campylobacter jejuni, Citrobacter fruendii, Proteus vulgaris
and Yersinia sp. The occurrence of some these bacteria
illustrate that fast foods in these restaurants may act as a
reservoir of pathogenic bacteria for human. Fungi isolated

foods containing vegetable salad and fresh vegetables more than
heated foods (e.g., chicken Shawarma, Beef burger). Some
bacteria resist heat and grown at 50oC.
Contamination occurred
through raw foods, use of polluted irrigation
waters, human handling
and the use of contaminated containers. The binge-eating of
fast food can lead to measurable signs of liver injury,
inflammation and inexpensive fat-and calorie-packed foods make
as the fattest. Food poisoning can be controlled by the
adjustment of pH, water activity, temperature control.
Prevention of toxins in fast foods must become a cooperative
effort on the part of all involved in food production. Prevent
multiply the microorganisms by washing and dry hands before
preparing any foods and after handling raw foods (meat,
poultry, vegetables or fruits), food preparation areas, equipment
must be cleaned, kitchen areas, restaurants and foods protected
from insects, pests and other animals. Patients should not
handle foods in restaurants. [Nature and Science

Abstract:
Selected
properties of automobile waste and non-automobile waste
(control) affected soils and its relation with some heavy
metals were investigated in this study. Sampling site was delimited
at each area by free survey technique and soil samples
collected at the surface (0-20cm) and subsurface (20-40,
40-60cm) depth. Results of the study showed decreased Ca, k, Mg
and CEC levels as well as increased Na content of the
automobile waste affected soil compared to the control. Both
soils were acidic in nature and their heavy metal contents
decreased with depth. Higher levels of heavy metals above
critical limits in automobile soils using standard were
observed .Soil contents of P04-, N03-
and sodium adsorption ratio (SAR) were within tolerable limits
in both soils. The results indicate that automobile wastes had
adverse effect on the nutrient level and fertility status of
the studied soil. [Nature

Abstract: Symbiotic germination has practical merit for both
conservation and horticulture, but it remains an underutilized
tool for orchids in peril on the Indian subcontinent. Dactylorhiza hatagirea
(D. Don) Soo - the subject of this study - is native to India, Pakistan, Afghanistan, Nepal, Tibet and Bhutan
where it is listed as endangered. We report our preliminary
findings aimed at growing D. hatagirea from seed using mycorrhizal
fungi leading to its reintroduction. Seeds were obtained from
capsules and sown on oat meal agar with fungi isolated from the
roots of mature D. hatagirea plants. Using molecular
characterization techniques, cultures were assignable to the
teleomorphic genus Ceratobasidium. Inoculated seeds resulted in
100% germination within 10 days of sowing, and healthy
protocorms were obtained after 40 days. Seedlings with well-developed
roots, tubers and leaves were obtained after 3 months. This is the first report
documenting the successful application of symbiotic seed
germination to reintroduce an orchid native to the Indian
subcontinent. [Nature and Science 2010;8(10):139-145]. (ISSN:

Abstract: Inula racemosa is an
important and critically endangered medicinal plant with
tremendous potential as an important natural resource. The
development of conservation and commercialization technique is
a priority at present. To assess this, rhizome splitting as a
means of vegetative propagation and seed germination for sexual
propagation were evaluated for mass multiplication of this potent medicinal herb of
North Western Himalayas. Split rhizome cuttings treated with
varying concentrations of IAA, IBA and GA3 showed
88.89±0.95% sprouting and 77.78±1.42% of rooting in 100ppm of
IAA. The studies undertaken on the seed germination of I. racemosa as a means of
mass multiplication
revealed that seeds show a broad range of
pre-chilling
requirements. Highest germination percentage-
90.00±0.30% were recorded when scarification and GA3
(100ppm) were applied together. Mean germination time declined
with higher concentrations of GA3 applied to
scarified seeds and also with increased duration of
stratification. [Nature and Science 2010;8(10):246-252]. (ISSN:

Abstract: Background /Aim: Generally, Breast cancer is much less
common in men than in women. Men tend to present with breast
cancer at an older age than women. Liver cirrhosis and
prolonged use of diuretics were found among most of cases.
Breast cancers that arise in men are more often hormone
receptor positive than female breast cancers. The most common
clinical presentation is a painless, firm, subareolar mass
Methods: The study included 6 patients with male breast cancer
that had been managed by the authors at Tanta University
Hospital over 3 years duration ; a minimum follow up period of
6 months was undertaken for all cases .All patients included
were symptomatic and finally diagnosed by preoperative biopsy.
All patients were studied for their clinical and pathological
features, presentations, their surgical managements and outcome
after surgery. Results:
The results of the study revealed that the disease was
early in 5 and was
locally advanced in one
patients. Their ages ranged between 46 and 73 years. All
patients were managed surgically with no reported
complications. Conclusion:
For definitive local therapy for men with breast
cancer; we recommend a modified radical mastectomy rather than
lumpectomy or more radical surgery. [Nature and Science 2010;8(10):253-259].

Abstract: The
antioxidant capacity of the Manilkara
zapota L. leaves extracts, obtained by sequential
extraction with different polarities of solvents, was evaluated
by four different in
vitro methods: DPPH, superoxide and hydroxyl radical scavenging activity and reducing capacity
assessment assay. The acetone extract showed best DPPH radical
scavenging activity; IC50 value 20 µg/ml almost
equal to that of standard ascorbic acid IC50 value
11.4 µg/ml. The
superoxide anion scavenging activity of acetone extract (IC50
= 140 µg/ml) was better than that of standard gallic acid (IC50
= 185 µg/ml). It showed good reducing capacity
assessment. The antioxidant capacity of acetone extract may be
due to its high phenolic content. The high antioxidant capacity
observed for acetone extract suggested that this plant could be
used as an additive in the food industry providing good
protection against oxidative damage. However, conformation of
its activity in in vivo
models should be carried out.
The work suggests that there
is no universal criteria for presence or absence of antioxidant
activity in different plants. It is imperative that one should
evaluate more than one antioxidant methods and in more than one
solvent in a single plant. [Nature and Science 2010;8(10):260-266].

Abstract: Due to the great economic importance
of banana crop, which emanates from the fact that it is
characterized by a high nutritional value, nice taste and
flavor compared to other fruit crops, availability in the
market during most of the year, and easy handling and storage,
the current study focused on exploring the potentials for
expanding the cultivated areas and improving the quality of
banana crop. Qalyoubia Governorate was selected to represent
banana production under traditional system, and Nubaria region
was selected to represent banana production under both
traditional and tissue culture systems. The study used
percentages to estimate the relative importance of banana
production areas and other economic variables. The study
concluded that banana grown by tissue culture outperformed
banana grown under traditional farming at the level of all the
studied economic variables, where average profit from tissue
cultured banana reached 591% the profit realized from
traditionally produced banana. Furthermore, it was found that
tissue cultured banana is better in terms of shape, taste, and
nutritional value, in addition to obtaining a crop that is free
of viral diseases. Therefore, the study recommended providing
support to expand in tissue culture banana production as a
substitute for traditional production in order to raise the
productivity thus exports of Egyptian banana. [Nature and

Economic Impacts of Climate change on
the Developing Countries particularly the Arab Countries
Dr. Ezzat Moulouk Kenawy
Faculty of Commerce-Economic
department-Kafrelsheikh University- Egypt
Email: bardis2008@hotmail.com
Abstract: The greenhouse effect is a world
phenomenon which can only be curbed through full international
cooperation at the individual, institutional and governmental
levels. The paper has found that the industrialized countries, which
are distinguished by their high rates of energy consumption
compared to the developing countries, are the main source
behind the eminences of greenhouse effect gases. Thus, they
have the greater role to take the necessary actions to curb the
eminences of these harming. These actions can be restricted in
two main trends: curbing the eminences of greenhouse effect
gases through the dependence on the alternative energy types
and improvement of fuel usage efficiency. In addition, the
green areas should be enhanced as the represent the main basis
to absorb carbon dioxide. As For Egypt’s attempt to face
the climate change, the Egyptian efforts are concentrated on:
implementing the clean development mechanism which Kyoto
protocol has approved, exchange information about the
dichotomies and reflections of the phenomenon on the
environment, enhancing the public awareness of the phenomenon
and its economic dichotomies, dealing with it, building
abilities, activating the international financial and technical
aids, adopting technology transfer as one of its priorities and
doing serious efforts to activate partnership programmes with
non-governmental organizations and associations. [Nature and

Abstract: A study was conducted
to investigate the growth of different yeast strains as influenced
by Acetic acid bacteria (Acetobacter aceti) during
fermentation of soursop juice. Preliminary studies were
carried out to identify the endogenous species of yeast
responsible for natural fermentation of soursop juice and the effect
of exogenous acetic acid and pH on growth and tolerance rate of
the different yeast isolates. The growth rate of different
isolates was monitored for 7th days with and without Acetobacter
aceti (AAB). Soursop juice was inoculated with the
different yeast isolates Saccharomyces cerevisiae (SC), Hansenula
anomala (HA), Canadida tropicalis (CA) and a brewery
strain Saccharomyces pastorianus (SP). Results
showed a reduction in maximal cell concentration with samples
treated with Acetobacter aceti. The inhibition of
growth rate was higher on non-Saccharomyces yeasts HA
and CA while the brewery strain SP indicated a higher tolerance
to Acetobacter aceti in the fermenting juice. Addition of 0.5ml v/v of exogenous acetic acid resulted in a
drop in pH from 6.8 to 4.1 and caused a reduction in cell count
while 1.0ml v/v acetic acid resulted in a drop of pH from 6.8
to 3.7 and showed complete inhibition of growth of all the
yeast isolates. When the medium was adjusted by 1N
hydrochloric acid to pH 4.1 and 3.7 all the yeast isolates
showed the same growth as the control (pH 6.8). [Nature and

Abstract: The ability of one bacterium and two fungi to
inhibit the mycelial growth of Mycosphaerella fijiensis was determined in this study.
The culture filtrates of the three microorganisms (Bacillus subtilis, Trichoderma asperellum and
Trichoderma
longibrachiatum) at different concentration were evaluated
in – vitro against mycelia growth of M. fijiensis on two culture media using spread
plate and mycelia dry weight method. Generally, the culture
filtrates of the three microorganisms had significant effect on
the mycelial growth of M.
fijiensis. Culture filtrates of Bacillus subtilis inhibited mycelial growth of M. fijiensis at
concentration of 1.5%, 2.5% and 5%. Trichoderma asperellum and Trichoderma longibrachiatum culture filtrates were
observed to be less effective at concentration of 1% and 1.5%
but became effective on mycelial growth of M. fijiensis at concentration of 2.5% and 5%. When
spread plate method was used, culture filtrates of Trichoderma asperellum
was observed to be highly effective than that of the other
microorganisms. When mycelial dry weight method was used,
culture filtrates of Bacillus
subtilis exhibited high antagonistic effect to mycelial
growth of M. fijiensis.
Malt extract agar and malt extract broth significantly (P <
0.05) supported the antagonistic activity of microbial agents
culture filtrates on mycelial growth of M. fijiensis compared to potato dextrose agar and
potato dextrose broth. Effective screening of microbial
biocontrol of Mycosphaerella
fijiensis can contribute to reduction in chemical
pesticides usage that has been reportedly linked to
environmental pollution and threat to public health. [Nature and

Abstract: The aim of this study is to provide
regulatory bodies and the operators that generate and manage
radioactive waste with some recommendations on how to meet the
IAEA safety requirements for the solidification of radioactive
waste. Safe management of radioactive waste includes treatment, solidification, storage and
disposal. The incorporation of radioactive waste into Portland
cement is the most widely used technique for its practical,
technological and economical advantages. Bentonite had high adsorption
capacity for cobalt and cesium but it decreases the compressive
strength when incorporated into Portland cement. To improve the compressive strength
and leaching behavior of final solid block, bentonite coated by
acrylic acid and styrene before incorporation into Portland
cement. The evaluation of mechanical integrity, chemical
properties, radiation stability has been carried out under
different experimental conditions. Bentonite additions to
Portland cement in excess of approximately 15 wt. % causes
significant decreases in the compressive strength of cemented
waste form. Also, it is found that the best waste isolation,
withought causing a loss in the mechanical strength, is
obtained when the bentonite content in the cement is 10 wt% and
it is reached to 25 wt.% by coated with acrylic acid and
styrene. The compressive strength for Portland cement
containing 10 wt. % T-bentonite was 67 MPa while T-bentonite
coated by acrylic acid
and styrene was 118 and 138 MPa respectively. Radiation dose to
solidified cemented waste form in excess of 1.5 Mrad causes
significant decreases in the mechanical stability, while at 1.5
Mrad the compressive strength increased to its maximum value. To
assess the safety for disposal of radioactive waste-cement
composition, the leaching of 60Co and 137Cs
from a waste composite into a surrounding fluid has been
studied. Leaching tests were carried out in accordance with a
method recommended by the IAEA. [Nature and Science

Abstract: Diabetes elicits an increase in the
oxidative stress-mediated endothelial dysfunction. Fifty male
rats were divided into two main groups, first group served as
control group was considered as normal non-diabetic (n=10).
Second group (n=40): rats were subcutaneously injected with alloxan
(150 mg/kg. body weight) for induction of diabetes. Then the
diabetic rats were divided into four equal subgroups as follows
comprising of ten animals each:
first was diabetic rats , and the second group was received
camel milk -treated diabetic group that was treated with camel
milk at a dose 40 ml/rat daily for four weeks. The third group was received camel milk
as previous combined with honey bee - treated diabetic group.
The fourth is honey bee dose of 10ml honey/kg/5ml of
distilled water diluted for four
weeks. Results show that the camel milk either alone or
combined with honey bee significantly reduced the hyperglycemia
from 217.69±0.70 nmol/µl (Diabetic untreated rats) to
126.8±0.68 nmol/µl and 115.90± 0.60 respectively. While, the
previous treatment significantly increased insulin hormone,
insulin growth factor 1(IGF-1) and interferon gamma-γ as
well as, lysozyme, glutathione peroxidase (GPx) and nitric
oxide (NO) as compared to the untreated rats. On the
contrary, the level of IFN-
γ in serum was increased in alloxan administered animals,
which was decreased significantly in rats had camel alone or
with honey bee. In
conclusion, the observations from this study show that camel
milk and or honey bee has hypoglycemic effect on
experimental diabetic rats. [Nature and Science

Abstract: Grafting of emulsified ethylene
propylene diene (EPDM) with vinyl acetate monomer (VAM)
EPDM-g-VAM via emulsion technique was carried out to get an
effective compatibilizer for blending (EPDM) with polar rubber
(NBR). Different doses of EPDM-g-VAM were incorporated in NBR/EPDM
blends. The optimum dose for compatibility process was
investigated by the rheological characteristics by using both
Mooney viscometer and melt flow indexer. The results were
confirmed by scanning electron microscope SEM. The ultimate
physico-mechanical properties of the vulcanizates (tensile
strength, elongation at break, swelling in motor oil and
thermal oxidative aging) gave evidence for the (EPDM-g-PVAc) as
an effective compatibilizer. Good results have been achieved
for the compatibility of these blends using 7.5phr of the
(EPDM-g-PVAc). [Nature and Science 2010;8(10):348-357]. (ISSN:

Abstract: In order to
investigate the
subsurface seepage conditions of the Ahmadu
Bello
University farm dam in Zaria, we
carried out a two-dimensional seismic refraction and electrical
resistivity survey along a profile spanning the axis of the
embankment. The ABEM
Terrameter SAS 4000 supplemented with the ABEM Lund,
multi-electrode, imaging system was used to obtain the
electrical resistivity data and the data processed using the
RES2DINV software. Also, seismic waves generated from multiple
shots along the survey profile were recorded at closely spaced
receivers installed along the profile using a 24 channel ABEM
Terraloc Mk 6 seismograph. The seismic data were analyzed using
REFLEXW version 3.0 interpretation software. Results show that
the anthropogenic, lateritic clay material of the embankment
has thickness ranging from 4 m to 12 m with p-wave velocity
ranging from 372 m/s to 937 m/s and electrical resistivity
ranging from 40 ohm-m to 85 ohm-m. The resistivity tomogram
shows evidence of inhomogeneity in the near-surface embankment
materials; this is an indication of differential saturation
interpreted to be associated with differential compaction and
or internal erosion. The seismic tomogram shows that the
underlying gneissic bedrock (1878 to 3383m/s) is capped by a
relatively lower seismic velocity zone in the range of 937 to
1690 m/s. This zone, with an average thickness of 4m, falls
within the low resistivity range of 40 to 85 ohm-m. It is
interpreted to represent a highly weathered and saturated
portion of the bedrock and the suspected seepage pathway for
water from the impounding reservoir. [Nature and Science

ABSTRACT: Cheilanthes
bicolor (Roxb), a rare fern of
Kumaun hills, is a member of psinopteridacea family of
leptosporangiate group of ferns. The fern fronds of cheilanthes bicolor
(Voucher Species No. 12) collected from Ranikhet and Jageshwar
sites of Almora Uttarakhand (India). The air
dried and powdered sample (1 kg) of botanically identified
species of cheilanthes bicolor (VS No-12) was extracted with
aqueous methanol (1:1) by cold percolation method for 6 days.
The major part of aqueous methanolic extract was evaporated to
dryness under reduced pressure in rota evaporator to dryness at
650c until only H2O layer (approx 50ml)
remained. It was partitioned with dichloromethane (50 ml) after
separation of CH2Cl2 soluble (lower
layer) the Upper layer of H2O further partitioned
with n-BuOH. In order to catalog all the flavoniods present in
the aerial parts of cheilanthes bicolor, 2 DPC was applied by
fresh aqueous methanolic extract on whatman No-1 paper using
BAW (n-BuOH-AcOH-H2O-4:1:5 v/v, Upper layer) and 30%
ACOH solvent system.After developing chromatogram the spots
were studied in visible and UV light both with and without the
presence of ammonia vapour and after spraying with NA
reagent.On the basis of UV, MS and 1HNMR the two compound
(1) with Rf value (83) kaempferol 3, 5 dimethyl ether and
compound (B) with Rf value (81) kaempferol -3- methyl ether. [Nature
and Science 2010;8(10):369-371]. (ISSN: 1545-0740).
