Abstract:
Rauvolfia vomitoria
(L.) is a species of tree in the family Apocynaceae. It is a
shrub or a small tree that undergo exploitation in some West
African countries. More concentration has been on the species of
Rauvolfia, that is, Rauvolfia serpentine which
makes Rauvolfia vomitoria lesser known species. Fruits of
Rauvolfia vomitoria were purposively collected from UI
(Oyo state) and FUTA (Ondo state) to determine Physical
characteristics (colour). The fruits were depulped, leaving the
seeds washed.
The length (cm),
width (cm) and weight (g)
of 100 samples per location were
measured to determine the influence of imbibitions and
seed index and analyzed. A t-Test was used to analyze and
compare the imbibition rate and seed index of the locations. The
ripe fruits in Akure (red) while the fruits in Ibadan (orange).
The unripe fruits in Futa (bottled green) while in U.I (pure
green) colour.
Mean
Seed indices
0.51 (Akure), 0.63
(Ibadan). Imbibitions
show a higher percentage of mean
0.013
at Akure than Ibadan (0.010).
The mature fruits of
Rauvolfia vomitoria are red and orange colour. Imbibitions
show a higher mean
0.013
at Akure had the best
imbibitions rate unlike Ibadan and might make the seeds to
germinate faster than Ibadan.

Abstract:
Greenhouse agriculture technology is considered one of the most
important applications of modern technologies that contribute to
increasing agricultural production, The research problem is
summarized in the imbalance between the supply and demand sides
of agricultural crops, especially with the limited land
resources and the increase in irrigation and water needs, in
addition to the worsening of the population problem, which aimed
to identify the feasibility of producing cherry tomatoes for the
purpose of export or local marketing under greenhouses. and
studying the development of greenhouse numbers in Egypt, it is
seen that it has taken an increasing trend with an annual growth
rate of about 5.14% of the average number of greenhouses during
the period (2004-2017). It is concerned with the development of
greenhouse production during the period referred to, as
production has taken an increasing trend with an annual growth
rate estimated at 3.96% of the average greenhouse production for
the study period. With an estimate of some indicators of the
economic evaluation of the production of cherry tomatoes under
the greenhouse, it was found that: the break-even point for the
production destined for the domestic market is estimated at 6.1
tons / greenhouse, and with an estimate of the price safety
limit for the production destined for export amounted to about
71.1%, which means that each product will still achieve profits
even if the export prices decrease by 71.1%, but in the case of
production Directed to the local market, the price safety limit
reached 27.2%. Which indicates that the cherry tomato product
under the greenhouse will still achieve profits until the local
market prices decrease by 27.1%, and it becomes clear that the
most important import markets for cherry tomatoes are the
markets of Saudi Arabia, Russia, Kuwait, followed by the markets
of the Emirates, the Netherlands, then Qatar, where they
represent These markets collectively account for 97.4% of the
total Egyptian exports of cherry tomatoes during the year
2017-2018, which indicates a concentration in the Egyptian
export markets among a limited number of countries.

Abstract:
In late 2019,
a novel coronavirus (COVID-19) was identified in Wuhan, a city
in the Hubei province of China. COVID-19 rapidly spread and led
to an outbreak in China and then became a global health
emergency.
Severe Acute Respiratory
Syndrome Coronavirus 2 (SARS-CoV-2 or COVID-19), showed high
transmission capacity and morbidity. In this way, WHO suggests
that the most efficient method for controlling transmission is
social isolation/quarantine to the population. Human and Swiss
Webster Outbred stock, in both species we can define a distress
intersection point: abrupt break in routine and compromise in
social relationships. For this reason, we can observe in the
Swiss Webster ethology various behavioral disturbances, such as
family violence and aggression exacerbated. In this review, we
hope, through comparative behavioral analysis, to avoid,
mitigate and alleviate social stress in humans, mainly through
procedures for raising animal welfare. In conclusion, we
believed that our knowledge of Mouse Lab ethology can be useful,
since, by minimizing stress, the most rudimentary emotions,
similar between humans and mice, but concient-rationalized in
the human and promote the improvement of the human being's
elevated quality of life, even in social isolation/quarantine.

Abstract: Background:
Chronic kidney disease (CKD) is the progressive deficiency of
renal function for months and years and frequently present with
elevation in markers of inflammation especially serum C-Reactive
Protein (CRP). CRP may have a clinical prediction for risk of
cardiovascular disease (CVD) which is the leading cause of
morbidity and mortality in patients with CKD. Aim of the
Study: This study was conducted to evaluate the effect of 8
weeks intradialytic aerobic exercise on (CRP) for patients with
chronic kidney disease. Subjects and Methods: Forty
hemodialysis patients of both sexes with chronic renal failure
participated in the study, their age ranged from 55 to 65 years
old recruited randomly from hemodialysis unit of October 6
university hospital, Giza, Egypt. They were randomly divided
into two groups (A & B). Study group (A) (30 patients) received
3 sessions per week for 2 months of intradialytic aerobic
exercise while Control group (B) (10 patients) received only
their medical treatment. All patients in both groups were
assessed through serum CRP, Blood urea, creatinine lab tests and
Borg rating of perceived exertion scale was used to assess
functional activity before and after treatment. Results:
The results showed that there was significant decrease in CRP,
urea levels and significant positive decrease in Borg RPE scales
scores in the study group pre and post treatment as compared to
control group. Conclusion: Intradialytic aerobic exercise
plays an important role in decreasing CRP, Urea and Borg RPE
scores for patients on maintenance hemodialysis.

Abstract:
The researcher believes that the lesson of physical education
needs to apply modern technological methods to be able to
achieve its goals optimally, as the introduction of modern
technology in the field of education may give us the opportunity
to eliminate that type of generations with limited culture and
skill and that non-good quality of education.
Therefore, the researcher sees the necessity to take advantage
of the capabilities offered by educational technology to raise
the level of skill performance by designing different and
effective educational environments and the optimal use of time
and working to increase understanding and awareness of the
correct motor performance. Therefore, the researcher has found
the necessity of carrying out this research to make optimal use
of technological innovations in designing educational programs
for basic skills in karate in a systematic framework organized
through the method of hypermedia
objectives:
The Paper aims at the following: 1. Designing an educational
program for basic skills in karate, using the hypermedia
technique. 2. Identifying the educational program effects on the
level of basic skills performance in karate. procedures: Paper
curriculum: The researcher used the experimental curriculum
because of its relevance to the research nature by using the
experimental design of two groups, one is controlled and the
other is experimental by using the post-measurement of the two
groups. Paper sample: The research sample was chosen
intentionally from secondary school students in Al-Salihiya
Educational District. The sample included (10) students who were
randomly divided into two equal groups, each of which (5)
students. results: Through the aims of the research and its
hypothesis, and according to what the results indicated, the
following conclusions were reached: 1. The experimental group
that used the computer software prepared with the technique of
hypermedia technique in some basic skills level in karate
surpassed the control group that used the (traditional) method
followed. 2. Computer software prepared with Hypermedia
technology was more effective in the performance level of some
basic skills in karate than in the traditional method.
recommendations: In light of the previous results, the
researcher recommends the following: 1. The necessity of using
computer programs that use hypermedia technique in teaching
different athletic activities' skills. 2. The computer science
courses in physical education colleges should include training
to use and produce educational programs. 3. The necessity of
expanding the establishment of educational technology
laboratories in colleges of physical education.

Abstract:
This study determined some physical properties of two varieties of melon
(Bara and Sewere) using standard methods of
evaluation. Properties determined include dimensional,
gravimetric and frictional properties. These properties were
investigated at 9.83 and 6.73% moisture content wet basis.
Sewere had the highest axial dimension (14.50, 9, 1.36 mm)
for length, width and thickness respectively while Bara
had 14.08, 8.34 and 1.17 mm respectively. Bara has the
highest Geometric mean diameter (4.35-6.75mm), while Sewere
has 4.15-6.62mm. Sewere has the highest arithmetic mean
diameter which ranged from 6.77-9.47mm while Sewere
ranged from 6.77-9.07mm. The sphericity of
Bara
and Sewere ranged
from 0.31-0.49 and 0.29-0.46 respectively while bulk density
ranged from 296.65 to 312.81 kg/m3 and 309.16 to 406.94 kg/m3
respectively. The true density and porosity of Bara is
higher than that of Sewere and it ranged from 1414.08 to
1580.32 kg/m3 and 79.02 to 80.42% respectively, while
the true density and porosity of Sewere ranged from
759.15 kg/m3 to 119.72 kg/m3 and 47.18 to
65.88% respectively. The highest coefficient of static friction
of 0.62 was obtained on plywood followed by glass with a value
of 0.42 while stainless steel has the least coefficient of
static friction with a value of 0.34 for Bara. Similarly,
Sewere has the highest value of 0.55 on plywood followed
by stainless steel with a value of 0.45 while glass has the
least coefficient of static friction with a value of 0.40. The
angle of repose of Bara ranged from 23.02 to 29.090
while Sewere ranged from 29.280 to 37.370.
The knowledge of physical properties is essential as guide in
design and development of various post harvest handling
equipment.

Abstract:
New (E)-4-((1,3-diphenyl-1H-pyrazol-4-yl)
methylene)-2-(4-nitrophenyl) oxazol-5(4H)-one
(3)
has been prepared by reaction of p-nitrohippuric acid
(1)
with 1,3-diphenyl-1H-pyrazol-4-carbaldehyde
(2).
Treatment of
3
with hydrazine hydrate gave the hydrazide derivative
4.
Refluxing 4
with 6N HCl afforded the imidazolone derivative
5.
Reaction of the hydrazide derivative
4
with benzoyl chloride yielded N-benzoyl derivative
6.
Refluxing 6
with 6N HCl gave triazinone derivative
7.
However, reaction of
6
with POCl3
yielded the oxadiazole derivative
8.
Aminolysis of
3
with primary and /or secondary aliphatic amines gave the
corresponding (E)-N-(1-(1,3-diphenyl-1H-pyrazol-4-yl)-3-substitueted-3-oxoprp-1-en-2-yl)-4-nitrobenzamide
(9a-d).
On
the other hand, refluxing
3
with aniline led to the formation of (E)-N-(1-(1,3-diphenyl-1H-pyrazol-4-yl)-3-oxo-3-(phenylamino)
pro-1-en-2-yl)-4-nitrobenzamide
(10).
Treatment of
3
with hydroxylamine hydrochloride in boiling pyridine yielded
oxadiazinone derivative
11.
The structures of synthesized compounds were elucidated on the
basis of IR,
1HNMR,
13CNMR,
MS data and elemental analysis. The prepared compounds were
tested for antibacterial, antifungal and anticancer activity.
The antimicrobial activities of the synthesized compounds have
been studied against gram positive bacteria, gram negative
bacteria and fungi by using agar well diffusion method which
showed that compounds
3, 7
were the most effective gram positive. Compounds
3, 7
and 8
were effective against gram
negative but less than gram positive. However,
compounds 3,
4, 5, 6
were more effective against fungi. Furthermore, anticancer
activities of some selected compounds were tested against human
hepatocellular (HepG2)
cancer cell line. Compound
6
showed moderate cancer cell growth inhibition. Also, the
anticancer activities against Ascitic Carcinoma showed that
compounds 6
showed
the highest antitumor effects.
