The significance of eosinophilic inflammation in asthma is well
established, while its role in COPD is still under
investigation, a proportion of patients with COPD exhibited some
degree of sputum eosinophilia. It is debatable whether
eosinophilia in COPD is related to concomitant features of
asthma. The aim of this study was to evaluate the role of serum
ECP and total IgE in differentiation between asthma and COPD in
both stable condition and in exacerbations. The study conducted
on 59 patients, 17 patients with COPD (10 with acute
exacerbation and 7 with stable COPD) and 22 patients with asthma
(10 patients with acute exacerbation and 12 with stable asthma).
20 healthy subjects were included as control. All patients were
subjected to: thorough history taking and clinical
examination, chest x-ray to exclude other underlying pathology,
ECG, and Spirometry. COPD staging was done according to Gold
study (2001), and estimation of serum ECP and total IgE was done
for all subjects. There was significantly higher level of serum
ECP and total IgE in stable COPD, acute COPD exacerbation,
stable asthma and acute asthma exacerbation when compared to
control, also level of ECP was significantly higher in stable
asthma group than acute asthma exacerbation in contrast to serum
level of Total IgE which was higher in acute asthma exacerbation
group than stable asthma. There was no significant difference
between serum ECP among acute versus stable COPD. There was
significantly higher level of serum ECP and Total IgE in total
asthma group than total COPD group. Also, there was higher level
of serum ECP and Total IgE in stable asthma than stable COPD and
higher level of serum Total IgE in acute asthma exacerbation
than acute COPD exacerbation. Meanwhile, there was no
significant difference between acute COPD exacerbation and acute
asthma exacerbation in serum level of ECP. No correlation was
found between serum ECP and FEV1, FEV1/FVC among asthma and COPD
patients. In Conclusion: eosinophil share in airway
inflammation and acute exacerbation of COPD. Asthma like
components of COPD can be explained by increased serum Total IgE
and ECP, also this could explain the variability and
heterogeneity of COPD. ECP and Total IgE cannot differentiate
between acute COPD exacerbation and acute asthma exacerbation
but may be a differentiating point in stable state.

rheumatoid arthritis consists of a group of childhood onset
Rheumatic disease having in common chronic inflammation of one
or more joints. The subtypes of juvenile rheumatoid arthritis
differ in clinical manifestations, prognosis and specific
immunological features. Genetic and environmentally associated
determinants interact, contributing to the development and
pathogenesis of juvenile rheumatoid arthritis. A characteristic
feature of juvenile rheumatoid arthritis is the interaction of
HLA genes within the same locus or between different loci that
increases the risk of the disease. Some HLA associations are due
to linkage disequilibrium between markers involved, but
accumulating evidence indicates that several different genes in
the HLA region are implicated in the pathogenesis of juvenile
rheumatoid arthritis. To determine the association of human
leukocytic antigen (HLA) class I and class II with juvenile
rheumatoid arthritis in Egyptian children and its relation to
clinical and laboratory findings. Fifty Egyptian children
patients with JRA and 40 controls were included. They were
subjected for complete clinical examination and Laboratory
investigation. Rheumatoid factor (RF) was performed using latex
test while antinuclear antibodies (ANA) were measured by ELISA.
For HLA-class I typing, lympho-microcytoxicity technique was
performed, while for HLA class II typing, PCR-SSOP using
innolipa was used. There was significant positive association of
JRA patients with HLA class I, HLA-A10, HLA-B (B13, B27, B35),
and class II, HLA-DR B1 alleles (*0101, *0102, *0801 and *1104),
HLA-DQA1 alleles (*0401), and HLADQB1 alleles (*0202, *0303,
*0603-09). While HLA-B12 and HLADQB1 *0602 were significantly
positive associated with healthy controls, also there was
positive association between HLA-DQA1 *0501 and HLA-DQB1 *0603
and pauciarticular onset JRA while polyarticular type was
positive associated HLADQA1 *0101. A significant positive
association was found between ANA positive patients and HLA-DRB1
*1104 allele. Conclusion: We conclude that there are some
associations of HLA markers with JRA and its clinical

Austempered ductile iron (ADI) with an austenitic
bainitic matrix is a new type of engineering materials and has
gained increasing interests in academic research and industrial
application due to its exceptional combination of tensile
strength and ductility. However, welding of ADI parts remains as
a great problem during manufacturing.
In this investigation, Shielded Metal Arc Welding (SMAW) was
attempted to weld ADI with AWS E11018-G, ENiFeCI and ENiCI
electrodes. The results obtained from SMAW were compared with
that produced from Gas Tungsten Arc Welding (GTAW) using filler
metal as stripes machined from base metal material. It was found
that welding with GTAW process using filler with the same
material followed by austempering heat treatment has superior
properties (mechanical and metallurgical)free from any
discontinuities compared with SMAW using different electrodes
for cast iron welding.

Abstract: In this
grafted and chemically treated low density polyethylene
has been used to remove cerium from
liquid radioactive wastes to level permitting their discharge
into the environment.
equilibrium techniques have been performed. The amount adsorbed
of Ce(III) ions has been studied as a function of initial pH of
solution, agitation time, adsorbate concentration and
temperature to find that the amount adsorbed of Ce(III)
increases with increasing initial Ce(III) concentration. Maximum adsorption of cerium (III) was found at pH 4 in an equilibrium
time of 120 min. The maximum adsorption capacity of LDPE-g-(PAAc)
untreated and LDPE-g-(PAAc) treated with KOH was found to be 34
and 37.1 mg/g, respectively. The kinetic sorption of
Ce(III) onto grafted and chemically treated polyethylene films
were studied using Lagergren equation
and the equilibrium rate constant for sorption was
calculated. The results obtained in
this study illustrate that the grafted and chemically treated
membranes is expected to be an effective and economically viable
adsorbent for Ce(III) removal from aqueous system.

Around the world and in Iran, female employment, especially in
rural area (which is a manifestation of participation) is not
raised the issue of unemployment. Matter is the work with no
reward. Because all the unpaid work is done that by women at
home such as cleaning, laundry, nursery and social affairs,
agriculture and livestock work and.... has come to account as
non-economic work. While the visible part of economic can't
continue to exist without goods and services of this invisible
section of the economy.

Asynchronous Transfer Mode Network (VoATM) Network is currently
a popular research topic as a real time voice packet
transmission method. The percentage of real time traffic (voice
and video) over Internet is rapidly increasing due to growing
trend of using real-time traffic oriented applications. People
want to talk, watch TV, do video conferencing etc over Internet.
This kind of real time traffic requires extra care because of
more delay sensitivity, minimum QoS requirements and limited
bandwidth. Simulation is the best way to study performance
evaluation for the Quality of Service (QoS). The goal of this
paper is to analyze the performance of QoS Guarantee and
presents the discrete-event simulation which provides detailed
and accurate network simulation results. Due to the increased
number of networks in existence and their greater complexity,
designing new systems and improving the performance of existing
ones has become more difficult and time consuming. It is
therefore more practical to use modeling and simulation tools
such as OPNET to deal with this complexity. It provides an
opportunity to examine the higher level and more complex
behavior of ATM networks. The software simulation package, OPNET
has many attractive features and can simulate large
communication networks with detailed protocol modeling and

The study examined the profitability of gum arabic production in
Data were collected using structured questionnaire supplemented
with oral interview among 150 respondents in four Local
Government Areas selected in the State. The data were analyzed
using descriptive and inferential statistics. The results
indicated that majority of the respondents (47.33%) were civil
servants and 70.66% had gum arabic farm size of 1 – 4 hectares.
The profitability analysis revealed that US$254,860.00 was
realized as total revenue and the gross margin (GM) was
US$243,557.46 which gives GM/ha/ year of US$344.68. The mean
profit per respondent was US$1,581.34. Also, the analysis of
revenue distribution among the respondents as calculated using
Gini coefficient showed that there was high level of inequality
distribution of revenue among the respondents. The study
identified some constraints facing the gum arabic farmers in the
study area and recommendations were made to overcome them.

Increasing income inequality and poverty continue to be the most
challenging economic problem facing
countries including Nigeria. Mean earnings also differ greatly
across groups defined by occupation, gender, education,
experience, and other observed traits. The paper explores the
extent to which a set of factors determine income growth
differential in rural Nigeria in the period 1996 to 2004 using
data collected by the National Consumer Survey of 1996 and
2003/2004 National Living Standard Survey. Using per capita
expenditure as an indicator of well being, Oaxaca Blinder
decomposition was carried out. Logarithm of per capita
expenditure was regressed on a set of determinants of economic
growth. From the decomposition result, the R2
for the two periods are 0.2739 and 0.3730 respectively.
determinants of growth for both periods respectively were:
age of household head
type of housing (0.038, 0.032);
level of education (0.129, 0.141);
and weekly hours worked (0.183×10-4, 0.002).

Diffusion Studies of Radioactive Wastes from the Concrete Matrix
by Dynamic Method
A. El- Dakroury
Hot lab. Center and
waste management Atomic Energy Authority, P.O. 13759 Cairo
In designing radioactive waste repositories, it is necessary to
predetermine the degree of cement performance change due to
leaching degradation. Cement is a porous material and consists
of solid phases in contact and in equilibrium with a pore water
solution. The progress of degradation can be expressed in terms
of water exchange cycles or speed of diffusion of ions in the
pore solution. Cementitious materials are fundamentally unstable
in water and will change properties with time. High pH
conditions of aqueous solutions in a radioactive waste
repository can be brought about by dissolution of cementitious
materials. In order to clarify the mechanisms involved in
maintaining this high pH for long time, the dissolution
phenomena of cement hydrate was investigated. In the present
research, leaching tests on powdered cement hydrates were
conducted by changing the ratio of mass of leaching water to
mass of cement hydrate Ordinary Portland cement hydrate was
contacted with pour water and placed in a sealed bottle. After a
predetermined period, the solid was separated from the solution.
hydroxide is one of the main reaction products resulting from
the hydration of Portland cement with water. It is also one of
the more soluble phases found in hydrated cement systems.
Studies of the influence of calcium hydroxide dissolution and
its effect under the dynamic leaching system were done .From
the results of XRD analysis on the solid phase and the calcium
concentration in the aqueous phase, it was confirmed that Ca
(OH) 2 was preferentially dissolved when the
liquid/solid ratio was 30 to 35 %, and that C–S–H gel as well as
Ca (OH) 2 were dissolved when the liquid/solid ratio
was 45% or larger. The crystalline phases were identified using
was carried out according to the ANSI/ ANS -16.1.

Mayurbhanj one of the largest district of Orissa, very much
famous for the Similipal Tiger Reserve. It is also well known
for the highest number of tribal population in the state. Most
of the tribal people depend on the forest and forest product for
their life and livelihood. Ethno medicinal studies in some
villages of the Mayurbhanj district resulted in the
documentation of many therapeutic uses of the locally available
medicinal plant resources. The present study deals with the
ethenobotanical perception of 48 plant species belonging to 29
families of medicinal plant used by the tribal people in the
rural area of Mayurbhanj district (Mostly Santal & Kolha) for
their primary health care problems. As the health care facility
is not accessible to the interior part of the district people
still depend on the medicinal plants and traditional health care
system for their health care. This paper illustrates some of the
medicinal plants used by the tribals of the locality for their
health care. The common diseases for which they are using these
plants are cough, cold, diarrhoea, gynecological disorders,
sexual debility, Malaria and other common fevers, anemia etc.

Biosurfactants are surface active compounds released by
microorganisms. They are biodegradable non-toxic and ecofreindly
Nowadays, the use of biosurfactant has been limited due to the
high production cost. Nevertheless, biosurfactants can be
produced with high yield by some microorganisms, especially
Pseudomonas sp. These microorganisms can use the various
renewal resources, especially agro industrial wastes, as the
potential carbon sources.
The production of biosurfactant by Pseudomonas sp using
the following Carbon (whey, used frying oil and rice water) and
Nitrogen source (ammonium
sulfate, sodium nitrate urea, and potassium nitrate)
sources were examined in this work. Whey as carbon and sodium
nitrate as nitrogen source were found to give the optimal yield
of biosurfactant production (9.2g/L).

Immunodeficiency Virus induces a wide array of biochemical and
immunological alterations resulting in the progressive
impairment of cellular functions, several metabolic
abnormalities and eventual development of acquired immune
deficiency syndrome (AIDS). There is paucity of information in
the plasma ascorbic acid concentration in HIV patients on
antiretroviral therapy in this community. This study was
designed to assess the interplay of ascorbic acid, lipids and
lipoproteins in HIV positive patients on antiretroviral therapy.
One hundred subjects consisting of fifty HIV positive patients
with mean age of 34.02 ± 0.95 years and fifty controls with mean
age of 35.06 ± 0.98 years were selected for this study. Plasma
ascorbic acid, lipids and lipoproteins were estimated using
spectrophotometric methods. The anthropometric indices were
measured using standard methods. The result shows significant
decreased in plasma HDLC (p<0.01) and body weight (p<0.05)
when compared with the controls. There were significant
increases in the plasma total cholesterol and LDLC (p<0.01) when
compared with the control values. The increase in plasma
triglyceride and decrease in ascorbic acid were not
statistically significant when compared with the control values.
There were significant correlations between TC and HDLC
(r=0.427, p<0.01) and LDLC (r=0.975, p<01).TC/HDLC was
negatively correlated with TC/LDLC (r=-0.782, p<0.01) and HDLC/LDLC
(r=-0.742, p<0.01). The main findings are significant increases
in plasma TC, LDLC (p<0.01), decreases in body weight (p<0.01)
and plasma HDLC (p<0.05) in our HIV positive patients on
antiretroviral therapy. The mean increase in plasma ascorbic
acid did not reach a significant level. (Ebesunu Maria, Finebone

focuses on the physiochemical analysis of fibre-cement and
beverage effluents using standard APHA method and Atomic
Absorption Spectrophotometry. Conductivity, biochemical oxygen
demand(BOD),total hardness, pH, metal ion content etc. of the
effluents were investigated. With respect to fibre-cement
effluent,65mg/l,1578mg/l,2027mg/l and 11were recorded for BOD,
dissolved solid, total solids, and pH, respectively. For
beverage effluent,40 mg/l,45mg/l,108mg/l and 8.67 were recorded
for BOD, dissolved solid, total solid and pH, respectively.
Results indicate that the values of parameters for fibre-cement
are relatively higher than that of beverage. Both effluents have
different levels of pollution loads since some of the major
indicators are above recommended standard limit.

Abstract: Policy makers
and service providers have increasingly come to view information
and communication technologies (ICT), and particularly the
Internet, as an important tool in providing disadvantaged groups
and areas with access to information, services and markets that
would otherwise be inaccessible.
In turn this has put increasing
pressure on policy makers, universities and other training
institutions to come up with approaches to inspire young
students to choose ICT for their studies. There is also a strong
argument for retraining many people who already have pre-service
and in-survive education, whether in the workforce or not, to
overcome to looming ICT skills crises. This paper reports on the
examination of these points. It will also explore appropriate
ways to combat this problem through analysis and identification
of real prospects for ICT education.

Aqueous, methanolic and ethanolic extracts of Allium sativum
(Lin), the popular bulbous spice plant was processed by
different methods employing a combination of plant/solvent
concentration, plant/solvent contact time and evaluated for
antibacterial and phytochemicalpropeties and tested against
standard sensitive strains of Staphylococcus aureus and
Escherichia coli. The results obtained showed that
pre-processed dried garlic samples were not active while freshly
crushed samples showed better antibacterial activity on bacteria
and that ethanol actually enhanced garlic’s antibacterial
activity. Antibacterial activity of garlic decreased over time
in ethanolic solvent but increased in methanol. The bulb was
also seen to minimal quantities of saponins and flavonoids and a
high level of hydrocyanides. The study suggests that garlic when
used in its raw form has better antibacterial activity, either
directly or as an adjuvant in a solvent. The significance of the
stability of garlic as an antibiotic is discussed. [Enyi-Idoh*
