Biofuctions are required for metals placed in the vicinity of
stenotic blood vessels. While compatibility is desired, dilation
of blood or prevention of the adhesion of platelets is most
important in the circumstance. Biomaterial grade titanium
was coated with polyethylene glycol for the studies of cell
adhesion and fibrinogen adsorption. The uncoated titanium oxide
surface showed a significantly high cell adhesion and fibrinogen
adsorption. While for the coated titanium oxide surface, cell
adhesion and protein adsorption was very low. The polyethylene
glycol coated titanium oxide surface can be deployed prevent
surface biofouling by proteins like fibrinogen. This inhibition
of protein adsorption prevents tissue growth allowing sliding
movements at stenotic blood vessels.

solid phase extraction (SPE) method was developed for the
quantitative separation of trace amounts of Fe(III) from
synthetic binary mixtures of Pb(II), Cu(II), Ni(II), Mn(II) and
Co(II). The cation-exchange resin Lewatite S100 has been
modified by adsorption on neutral red dye at pH 3.0+0.5.
Binary separations of important metal ions were achieved on the
basis of their distribution coefficient (Kd) values
when chromatographed with different mobile phases at room
temperature. The values of separation factor (α) and recovery(
%) were evaluated by batch technique for predicting the
conditions for the possible separations on column in presence
of different mobile phase.

Powdery mildew fungi have been known to cause heavy loss to
various crops every year through out India and across the
world. Keeping this in view, a thorough survey was carried out
in four districts of
valley, viz. Kupwara, Baramulla,
and Anantnag in order to assess the incidence and severity of
the disease on some plants of family Papilionaceae. It
was revealed from the study that the plants such as Phaseolus aconitifolis, Phaseolus aureus, Phaseolus vulgaris, Pisum
sativum and Robina pseudoaccacia showed moderate to mild
infection in different localities of Kupwara and Baramulla
whereas P. aconitifolis, P. aurens, P. vulgaris
and P. sativum showed mild infection in different
localities of district Kupwara, Baramulla, Srinagar and Anantnag
during the study. However, no infection was observed in some
areas of the valley on plants of Papilionaceae surveyed during
the study. The overall study reveals the need for the management
strategies at the early stage before the disease can spread

Fundamental to optimal location of facility is some measure of
point-to-point distances. Distance measurements used in facility
location are predominantly based on Rectilinear and Euclidean
distances. This paper presents “great circle distance” which
represents the shortest path for distance modeling and optimal
facility location on spherical surface. Great circle distances
takes into consideration the geometrical reality of the
spherical Earth and offers an alternative to widely held notion
that travel over water can be exactly modelled by Euclidean
distances. The need for geometrical presentation of the
spherical earth becomes very relevant when we take into
consideration an ever increasing facility location at sea where
great circle travel can be practised. Facilities being located
at sea include oil rigs, mobile drilling units and dynamically
positioned units. The use of “Great circle distances” opens up
another avenue for convergence of Navigation and Spherical
Trigonometry into advancement of logistics and facility
location. In this paper an evaluation of single facility
location using great circle distances is used to demonstrate the
application of the concept.

Introduction: Pancreatitis is the most common complication after
ERCP. The reported incidence ranges from 1% to 24%, depending on
the study population, the endoscopic procedure, and disease
definitions. Objectives: The study had two objectives. The first
was to assess the incidence of post ERCP pancreatitis in cases
of failed biliary access after manipulation of the pancreatic
duct with multiple cannulations, dye injection and/or guide wire
cannulation. The second objective was assess the benefit of
pancreatic duct stenting in high risk cases especially those
with failed biliary access and had pancreatic duct manipulation
in cases with calcular obstructive jaundice. Methods: This is a
prospective randomized study which included 50 patients
presented with calcular obstructive jaundice, all patients
diagnosed with malignant obstructive jaundice or had a previous
attempt of ERCP were all excluded. Patients who had more than 10
attempts of CBD cannulation which ended with pancreatic duct
cannulation were all randomized for pancreatic duct stenting
using closed envelops. Results: A total of 50 cases were
included in the study. The study included 28 females and 22
males with a mean age of 50 years. The indication of ERCP was
due to calcular obstructive jaundice in all 50 (100%) patients.
The overall incidence of post ERCP pancreatitis was 7/50 (14%),
mild pancreatitis in 5 cases and moderate in 2 patients, none of
the patients had severe pancreatitis. Females had an overall
incidence of pancreatitis of 14.3% while males had an incidence
of 13.4 %. Conclusions: Incidence of pancreatitis is more in
cases with failed biliary drainage. Pancreatic duct stenting
after manipulation of the pancreatic duct is safe and successful
in decreasing the incidence of post ERCP pancreatitis whether it
was successful or not to drain the biliary system.

It is known
that toxoplasmosis rarely leads to various liver pathologies.
Hepatocellular carcinoma (HCC) patients are subject to a variety
of cellular as well as humoral immunity disorders. Also,
hepatitis C virus (HCV) infection is now recognized to be a
major risk factor for HCC which triggers tolerance breakdown in
specific conditions. It is aimed in this study to investigate
the frequency of toxoplasmosis in patients with HCC.
Serum samples from 134 HCC patients
undergoing surgery and 205 samples from asymptomatic individuals
were used for screening of HCV antigen and Toxoplasma
antigen (Toxo-Ag) using ELISA. 96 out of 134 serum samples (72%)
of HCC patients and 51 out of 205 serum samples of asymptomatic
individuals (25%) were positive for HCV antigen. 36 KDa
Toxoplasma antigen was purified
from sera of HCC patients using electroelution technique
and quantified in serum samples.
A dose-response curve was constructed to estimate Toxo-Ag in
serum samples and the
cutoff level was set at 1.35 ng/ml. Of the 96 HCC patients
associated with chronic HCV infection, 52 (54.2%) were
positive. However, of the 38 HCC patients non-infected with HCV,
14 (36.8%) were positive for
10 out of
the 51 (19.7%) asymptomatic individuals positive for HCV-Ag were
positive for Toxo-Ag . Also, 30 out of the 154 (19.5%)
asymptomatic individuals negative for HCV-Ag were positive for
Toxo-Ag. A positive significant correlation was found between
the concentration of Toxo-Ag and HCV-Ag in patients with HCC.
There is a new lethal coinfection of HCV and Toxoplasma;
each may accelerates the course of the other.

Glypican-3 (GPC3) is a member of the glypican family of heparan-sulfate
proteoglycans (HSPGs), which are linked to the cell surface
through a glycosyl-phosphatidylinositol anchor.
present work was suggested to use the ELISA technique,
monoclonal antibody (GPC3 – mAb),
to identify and quantify the GPC3 levels in serum
samples from patients with
pancreatic, stomach and esophageal
cancers. Obtained results
revealed that there was a highly significant difference
in GPC3 levels between pancreatic
cancer patients and healthy individuals.
Positive GPC3 samples were detected in 35 out of 40 pancreatic
cancer samples with a sensitivity 87.5% and specificity
100 % compared to healthy individual
samples while the overall accuracy of the test was 90.7%.
Results revealed also that there was no significant
difference in the levels of serum AFP between pancreatic cancer
patients and controls. A significant difference in serum GPC3
levels was also found between
pancreatic cancer patients and gastric cancer patients.
GPC3 protein might be over expressed in patients with pancreatic
cancer with subsequent release into blood circulation enabling
its assay using the noninvasive ELISA technique that optimized
based on specific monoclonal antibody (GPC3 – mAb). In conclusion; GPC3 is more sensitive tumor marker and can be
used as a diagnostic and prognostic marker for pancreatic cancer
and it is preferred as a tumor marker than the classical tumor

Different methods in distance education
1, 2Damavand Branch, Islamic
Azad University, Damavand, Iran
High front-end costs
prevented an early widespread adoption of electronically
mediated learning. Distance learning has been aggressively
adopted in many areas because it can meet specific educational
needs. As the concept of accountability became accepted and laws
required certain courses in high school in order for students to
be admitted to state colleges, telecommunications was examined
as a way to provide student access to the required courses. Many
rural school districts could not afford the special teachers to
conduct required courses. Distance education met this need by
providing courses in schools where teachers were not available
or were too costly to provide for a few students. It also
fulfilled a need for teacher training and staff development in
locations where experts and resources were difficult to obtain.
These systems link learner communities with each other and bring
a wide array of experts and information to the classroom.
Enjoying and giving publicity to any
of technological tools with the aim to facilitate and accelerate
the training process, as well as increase the quality and
quantity of knowledge quality and knowledge of a serious
intelligence community needs to integrate and standardize the
educational system society. Hence, considering the position and
role of education in the third millennium on the basis of ICT is
also a serious approach to the topic with the knowledge
community centered on learning and general trends of
technological tools to enjoy much of the information and Find
the appropriate place in the information society Third
Millennium That actually can be a global community and is
without limit is undeniable-and-run. Guidance and therefore move
in the direction of society should be education and technology
for comprehensive pandemic done. Considering the above
definitions and with the knowledge and attitudes towards the
third millennium and the desirability and some weaknesses in the
achievement of certain standards and dynamic structures in order
to achieve a knowledge based society, there is. In the present
circumstances to provide our information infrastructure
development and integration inevitably link the elements and
tools that they are as indicators of technology education and
technology education will be remembered. In the new context of
combining these two indicators comes to training facilities and
a variety of tools that will provide guidance and development in
information will be very effective.

the information in the development of any society should take
half of the world to progress until the necessary coordination
and synchronization global developments so as to accept the
design structure of a knowledge-based society have a special
place for the University and respect the role of education and
technology was In designing a model with global standards of
dynamism and flexibility at first be necessary to select a
sample that the facilities and communications needed for this
purpose provide action and then determine optimal cognitive
deficiencies than Hammett and weaknesses push. No doubt the
experiences of implementing these standards and to develop
troubleshooting information using technological tools would be
much more economical. That if we develop a range of information
from a city university level and conduct more successful we'll
be more acceptable was. Because the utilization and application
tools and step up the information they've been successful.
Therefore the most important first step needed to coordinate and
synchronize technology education and educational technology
standards and capability in the high user acceptability of the
world is also enjoyed. Historically, most distance education
courses were vocational in nature, but today courses are offered
for academic, professional, and avocational purposes for
students of all ages. There are numerous specialized programs,
such as those for blind persons and for parents of small
children with hearing impairments. Distance education is
available in practically any field, from accounting to zoology.
Courses are offered in gemology, high school diploma,
journalism, lock smiting, child day care management, yacht
design, and many fascinating subjects. Distance education
courses also vary greatly in scope, level, and length. Some have
a few assignments and require only a few months to complete,
while others have a hundred or more lesson assignments requiring
three or four years of conscientious study.

The background of distance education to mid-nineteenth century
dates. Pioneers in America and Europe of the best distance
learning technologies for training that day, took advantage. For
example: mailing system for creating educational opportunities
for those able to go to regular schools were not interested in
science education, but had been used. Of course at that time
most of those who took advantage of this type of Physically
Handicapped facilities, women allowed to attend the classes
along with men who did not have a. Location is N. There was a
school; were. One of the pioneers in this field English personal
name was Isaac Pitman. His short-term training through
correspondence and the correspondence began in 1840 in England.
Students were required to read the Bible a part of written
questions and answers raised by Pittman to get a good score
should return by mail.
Challenges which faced the early users of distance education are still
with us today. If distance education is to play a greater role
in improving the quality of education, it will require expanded
technology; more linkages between schools, higher education, and
the private sector; and more teachers who use technology well.
Teachers must be involved in planning the systems, trained to
use the tools they provide, and given the flexibility to revise
their teaching. Federal and state regulations will need revision
to ensure a more flexible and effective use of technology.
Connections have been established across geographic,
instructional, and institutional boundaries which provide
opportunities for collaboration and resource sharing among many
groups In the pooling of students and teachers, distance
learning reconfigures the classroom which no longer is bounded
by the physical space of the school, district, state or nation.

family supervisor too. In spite of that rural women in
developing countries are producer of about 80% of foods and
responsible of supervising of about 30% of rural families, but
their activities wasn’t considered as economic activity and
simply are removed from agriculture and rural development
programs. Base on formal existing statistics, women form about
31% of agriculture active workforce in developing countries.
While, informal and local statistics, estimate number of working
women at agriculture part more than formal statistics. In Egypt,
base on formal statistic, rural women’s activity has been
reported about 36 %. While local statistic represents between 35
to 50%. Base on formal statistic at many African countries (e.g.
Congo) women’s share at preparing labor workforce at agriculture
part is 60% but base on informal statistics, above share is
reported 80%. This statistical difference exists at most

Hepatitis C virus infection is the
leading cause of advanced liver disease. The
prevalence rates of infection range from 0.5-2% in the developed
world, through 6.5% in parts of
equatorial Africa, to as high as 20% in Egypt.
Nitric Oxide is a short-living biological mediator generated
from L-arginine by NO synthase (NOS)
and it possesses a wide range of
physiological functions. The present study aimed at the
determination of NO levels in sera of HCV- infected patients
compared with its levels in sera of non-infected individuals.
250 serum samples from patients with different liver affections
were screened for HCV infection including anti-HCV antibodies
(HCV-Ab) and HCV antigen (HCV-Ag) using ELISA technique in
addition to 30 serum samples from healthy individuals as
negative controls. The Detection of anti- HCV-Ab revealed that
150 serum samples are positive. In addition, a total of 30
healthy individuals were negative for anti–HCV Ab. The detection
of HCV-Ag revealed that 129 serum sample were HCV-Ag positive
while all controls were negative for HCV-Ag. All 129 individuals
showing positive anti-HCV and HCV-Ag were classified
histopathologicaly into 3 groups: non-cirrhotic liver (n=70),
cirrhotic liver (n=23) and hepatocellular carcinoma (HCC)
(n=36). HCV-Ag was detected in non-cirrhotic patients, cirrhotic
and HCC patients with detection rate 96%, 74% and 94%
respectively. In non-cirrhotic patients serum NO was detected in
a rate of 91.4%, in cirrhotic patients the rate was 91.3%
and in HCC patients it was detected in a rate of 63.8%
.There were statistically significant differences between the
mean NO concentrations of the different pathological
classifications of the liver disorders compared to that of the
control group. A significant correlation was shown between the
NO levels and the HCV-Ag levels in sera of HCV patients with
different pathological classification of liver disorders. It is
concluded that the elevated serum NO level accompanies
HCV-infection and correlates well with active viral infection
indicated by high HCV-Ag levels.

mercury chloride is a xenobiotic metal that is a highly
deleterious environmental pollutant. The biotransformation of
mercuric chloride (HgCl2) into methyl mercury
chloride (CH3HgCl) in aquatic environments is
well-known and humans are exposed by consumption of contaminated
fish, shellfish and algae.
The genotoxicity induced
by mercury compounds remains controversial.
Therefore we have
investigated the genotoxic effect of methyl mercury chloride
(MMC; CH3HgCl) at two concentrations (100, and 1000
and the role of ascorbic acid
(Vitamin C) at a single concentration of (9.734 mm) on
MMC-treated short-term human lymphocyte cultures. We assessed
the chromosomal aberrations (CAS), sister chromatid exchange
(SCE) and COMET assay in control and MMC-treated lymphocyte
cultures with and without Vitamin C supplementation.
The results showed that
MMC has increased the frequency of CAS and SCE/cell in a
dose-dependent manner than control values. CH3HgCl
also, induced DNA damage in determined by COMET assay.
These effects were prevented by the addition of Vitamin C to
MMC-treated lymphocyte cultures. Data revealed that, mutagenic
activity of MMC and the protective role of Vitamin C on mercury
compounds-induced genotoxicity in human lymphocyte cultures is
probably due to its strong antioxidant and nucleophilic nature.

replicated twice. Nine of the ten groups were fed single phase
diets of varying protein and energy levels, while the tenth
which was the control was fed the two stage diets (0-5 weeks
starter phase, and 6 – 8 weeks finisher phase). A 3 x 4 – 2
factorial design which was an adaptation of 3x4 factorial design
was used in this experiment. Feed and water were served ad
libitum throughout the duration (0-8 weeks) of the
experimental period. All necessary vaccinations and preventive
medication were carried out at various periods of the
experiment. The parameters measured in this experiment were
body weight, body weight gain, feed intake and feed to gain
ratio. Data were analysed with the aid of a computer package SPSS for windows, version 11.0 (2000). Results showed that birds
on low protein-high energy diet (T7) had the least values in
most of these parameters measured. Birds on low protein-medium
energy (T8) and high protein-low energy (T3) diets performed
best in these parameters. Diets T8 and T3 were therefore
recommended as the best to be used under the single phase

The weekly average of seven weather variables viz. rainfall,
maximum and maximum temperature, relative humidity at 7.00
am and 2.00 PM., bright sunshine hours and pan evaporation
of 39 years for the month of June were collected from the
IMD approved Metrological Observatory situated at GB Pant
University of Agriculture and Technology, Pantnagar, India.
Comparisons of the forecasting models were made to identify
the appropriate model for the prediction of rainfall.
Stepwise regression analysis was used to identify the
significantly contributed variables. These selected
variables were used for Artificial Neural Network analysis.
The Neural network work tool of Matlab is used for
prediction of weekly rainfall. The data were analyzed to
find the mean, standard deviation and minimum and maximum
value for all the seven variables. The inter correlation
between these variables were also observed. The result shows
that the variability in rainfall during the month of June
was highest among the all variables and it was lowest for
minimum temperature and the correlation between rainfall and
relative humidity at 2PM was maximum (0.5529) and it was
minimum between rainfall and minimum temperature (-0.0224).
The result shows that the value of the coefficient of
determination (R2) = 50.91% for multiple
regression model while it was 76.68% using neural network
model, secondly, the prediction error for multiple
regression model is 0.368 which is higher than that of the
prediction error obtained through neural network model as
0.131 and thirdly, the absolute mean value is 13.393 for
regression model and 4.796 for neural network model which
further indicate that the mean absolute difference from
actual rainfall is less obtained through the neural network
method. Finally on the basis of maximum value of coefficient
of determination(R2), minimum prediction error
and minimum mean difference it was concluded that neural
network approach is better than multiple regression approach
for predicting weather parameters.

This study was conducted to examine the effect of glutamine and
casein concentrations on callus growth and somatic embryogenesis
of date palm (Phoenix dactylifera L.). Explant derived
from offshoot tip was cultured on MS medium containing four
different macro nutrients and different concentrations of casein
and glutamine. The type and concentration of amino acid
significantly affected the size and differentiation of date palm
explant. As concentration increases the size and differentiation
decreases up to 40% especially with casein, while 3gl-1
casein increase the callus weight up to 80g comparing with
control which gave 20g. The best result of somatic embryos per
treatment achieved with half macro nutrient medium supplemented
with 3gl-1 casein This study provides an insight into
the importance of optimizing various culture medium and amino
acid components to overcome in vitro recalcitrance of date palm.
