Abstract:
This paper demonstrates the students’ attitude towards English
language learning at secondary level education. The present
study is implemented by following 57 students in the secondary
level education in Bangladesh. The findings suggested that
students were not generally comfortable with the language
environments and courses offered in secondary settings; they
agreed that learning English is important for them. The
respondents in the present study, who had just obtained their
primary education, reported that the syllabus in secondary level
(school) helped them obtaining the language needed for career
and personal growth. The findings of the study also showed a
positive attitude towards the learning of English at the
secondary level education in Bangladesh.

Abstract: A
study was conducted to investigate the prevalence of nematodes
of domesticated guinea fowls slaughtered at the Maiduguri
central market. Postmortem examinations of 100 samples each of
trachea and gastro-intestinal tracts revealed an overall
prevalence of 90%. Male guinea fowls had a higher prevalence of
infection 35.6% compared to the females 64.4% (p >0.05).
Parasites identified were Heterakis gallinarum
with 20%, Ascaridia galli 6.7%, Subulura
brumpti 13.3% Strongyloides avium 11.1% and
Capillaria bursata 2.2%. Mixed infections were those
by Ascaridia galli and S. avium 15. 6%, H.
gallinarum and S. avium 15.6%, H. gallinarum
and Subulura brumpti 6.6%, A. galli and H.
gallinarum 6.6 % and S. avium and Sub. brumpti
and A. galli and Syngamus trachea with 2.2%. These
findings indicate that guinea fowls harbor nematodes that are
parasitic, and the effect of these parasites on the productivity
of the guinea fowls is discussed. Some factors of these
parasites are also considered.

Personality Racism and
Non Issue-Based
Conflict: An
Easy to Espouse Self-Management Theory

Abstract:
This research is tackling a triple-link among personality,
self-management and conflict. It shows how personality may
represent the base that allows individual a sort of
self-management against the non-issue based conflict. It
suggests that the big deal of people's conflicts and problems
inside organizations is steaming from their insisting to deal
with people who have the same personality type and/or
characteristics as they have. This is hardly occurred in
reality, due to the normal creation of people as different from
others. Primary data that are firstly collected from the field
by questionnaire and then statistical test processing were the
two steps which have been successively used to examine such a
triple-link. The previously mentioned three variables were
hypothetically expressed to show; personality racism as
independent variable, self-management as a mediator, and
non-issue based conflict as dependent. This was occurred
indirectly through testing two interrelated hypotheses and then
directly through another hypothesis to certify the link between
the independent and dependent variables without using the
mediator. There was a statistically indicative significant
relationship between the independent and dependent variables
with and without the intermediary one. The field study chosen
for empirically conducting this research was the Egyptian
university hospitals, and the population targeted inside theses
hospitals through a stratified random sample was precisely
represented in the academic staff doctors working there.
Creating people's awareness and acceptance of personality
differences were the two invaluable advices to recommend for
having an easy to use self-management theory against the big
amount of interpersonal non-issue based conflicts.

Abstract:
Lasianthera africana, Heinsia crinata and
Gongronema latifolium were screened for their phytochemical
contents and composition, while vitamin contents, mineral
elements and proximate values of the plants were analysed using
standard procedures. A comparative analysis of the results
showed that alkoloids and cardiac glycosides were not detectable
in G. latifolium which rather contains high levels of
other phytochemicals such as anthraquinones (23.3+0.03mg/100g),
cyanogenetic glycosides (19.0+0.00mg/100g), saponins
(18.2+0.02%), tannins (16.1 + 0.03mg/100g) and
flavonoids (11.0+0.10mg/100g). However, L. africana
and H. crinata had some phytochemical contents and
compositions such as saponins (15.9+0.00% and 16.1+0.01%
respectively), besides some levels of tannins (10.0+0.00mg/100g
and 0.3+0.00mg/100g respectively), pointing to their medicinal
potentials. Nutritionally, G. latifolium had
significantly high concentrations (P < 0.05) of vitamins A, C, E
and niacin, besides minerals such as Se, Cu, Mg and Cr, while
thiamine was significantly high (P < 0.05) in H. crinata. Carbohydrates, proteins and fibre were relatively high in the
three plants, unlike fat which was equally low. It is concluded
that, although the three plants are medicinally and
nutritionally potent, G. latifolium appears to be most
potent.

Abstract:
Cryptosporidium
spp.
and
Giardia
duodenalis
are
2
protozoan
parasites
that
affect
humans
and
a
wide
range
of
domestic
and
wild
animals.
These
parasites
are
a
major
cause
of
diarrheal
disease
in
humans
and
animals
worldwide,
causing
high
morbidity
in their
hosts,
in
immunocompromised
hosts
and
children,
they
can
lead to
death.
The
purpose
of
this
study
was
to assess
the
frequency
of
Cryptosporidium
spp.
and
Giardia
spp.
in the
northern
part
of
Delta (Damietta
governorate)
and
the
risk
of
human
infection
of
these
protozoa
related
to
personal
data,
socio-cultural
and
environmental
characteristics,
and the
presence
or
absence
of
symptoms/signs
among
a
rural
and
urban
population.
In
order
to assess
the
prevalence
of
these
protozoa
among
population
in
the
northern
part
of
Delta and
the
risk
of
human
infection,
330
people
(175
females
and
155
males)
with
or
without
symptoms
who
attended a
Health
Care
Center
were parasitological
studied.
Of
the
surveyed
population
(330),
3.6%
were infected
with
Cryptosporidium
spp.
only
or
24.2%
with
Giardia
spp.
and
2.4 %
were
infected
with
both
protozoa.
The
frequency
of
infection
according
to sex;
2,7%
of
males
were
infected
and
0.9%
of
females
by
Cryptosporidium
spp,
12.7%
and
11.5%
by Giardia
spp.
and
1.5%
and 0.9%
by
both
parasites,
respectively.
Cryptosporidium
spp.
and Giardia spp.
was
frequent
in children
(under
12
year)
than
adults
in
both
sexes,
however,
Cryptosporidum
infections
were
most
frequently
diagnosed
in
children
less
than
12
years
old
and
prevalence
decreased
with
age.
The
prevalence
of
these
protozoa
in this
community
are
lower
than
those
reported
by
other
studies,
which
is
probably
associated
with the low
density
of
the
studied
population.
Studies
analysis
revealed
that a
male
sex,
children, loss
of
weight,
impropal
waste
disposal,
diarrhea
and
abdominal
pain
were
correlated
with
the
presence
of
these
parasites,
which
indicate
the
importance
of
these
factors
in
rural
communities.

aia_hassan20@yahoo.com
Abstract:
Kombusha is benefit to people
suffering from cancer due to increasing its acidity by the
bacterium. This study to isolate and identify the bacterium
samples from tea kombusha. Six acetic acid bacteria were
isolated from traditional Kombusha fermentation of tea belong to
the family Acetobacteraceae, genera Gluconacetobacter and
Acetobacter. Acetic acid productivity yielded isolate No.1 that
produced higher amount of acid. The isolate was catalase -
Positive, oxidase – negative, strictly aerobic, Gram-negative
rods, grow on yeast extract with 30% glucose and grow on
glycerol variable on maltose but not methanol as carbon sources.
The isolates oxidized ethanol of yeast kombucha to acetic acid
therefore they were tentatively identified as Acetobacter
species. The hight producer of acetic acid (11.2) was selected
for identification by 16S rRNA gene sequences and phylogenetic
analysis confirmed their position in the genes Acetobacter.
On GYC agar, colonies are beige, round, convex, smooth and shiny
and approximately 0.8mm in diameter after incubation at 28˚C for
4 days. The PCR product with size of about 1500 bp DNA was
amplified. Based on the genotypic and phenotypic data, the
isolate represent species of genus Acetobacter for which
the name A.aceti is proposed.

Abstract:
This
work
was
carried
out for the biosynthesis of antimicrobial
substance
that demonstrated inhibitory
effects against microbial pathogenic from
Streptomyces
crystallinus,
AZ-A151.
The active metabolite was extracted using ethyl acetate (1:1,
v/v) at pH 8.0. The separation of the active ingredient of the
antimicrobial agent and its purification was performed using
both thin layer chromatography (TLC) and column chromatography
(CC) techniques. The
physico-chemical characteristics of the purified antibiotic viz.
color, melting point, solubility, elemental analysis,
spectroscopic characteristics and chemical reactions have been
investigated. This
analysis indicates a suggested imperical formula of
C15H30N2O10.
The minimum inhibition concentrations "MICs" of the purified
antimicrobial agent were also determined. The purified
antimicrobial agent was suggestive of being belonging to
Hygromycin-B, antibiotic
produced by
Streptomyces
crystallinus,
AZ-A151.

Branch Status Topology Errors Detection in power
System State Estimation
S. Ahmed

Faculty of Engineering, Al-Azhar University,
Cairo, Egypt
sayed.nagy@gmail.com
Abstract:
In order to run the state estimator, it must be known that how
the transmission Lines are connected to the load and generation
buses. This
information
is called the network topology which also determine the
bus level network model of a power system based on the
te1emetered status of the circuit breakers at the substations.
Since the breakers and switches in any substation can cause the
network topology to change, a program must be provided that
reads the telemetered breaker/switch status indications and
restructures the electrical model of the system.
Also, any
errors in the te1emetered or manually updated status of the
circuit breakers will lead to an incorrect bus level network
model.
This paper presents A pre-processing algorithm for detection of
the statues of the suspected lines in electrical power system
networks before state estimation solution. an algorihm is
domenstrated,which handle the branch status error
