Abstract:
Project failure
which occurs in all countries of the world, is an embarrassment
to any country where it occurs, especially developing countries
where the failure is more frequent. Generally, project
implementation is characterized by success implementation, delay
and failure. Thus, efficient practices ought to be relied upon
to mitigate failure and delay. The aim of this study was to
investigate and analyse the causes, effects and consequences of
project failures across Nigeria. A systematic literature review
of scholarly publications relevant to Nigeria to establish the
findings and answers to the three research questions selected
for this study was adopted. In this study, the following causes
of project failure were identified: poor communication between
the various stakeholders in public projects within Nigeria; poor
contracting and contractor practices; poor planning and
estimation; frequent design scope changes and errors; lack of
adequate resources and bureaucracy; socio-cultural and political
interferences; and poor leadership and corruption. Also, the
effects of project failure identified were: loss of State
revenue; project cost overruns; loss of revenue by citizens;
substandard infrastructure; and low empowerment to community.
Accordingly, the consequences of the failure were identified as
follows: slow economic growth; sector-centric underdevelopment;
loss of foreign aid/grants; tougher donor regulations; loss of
elections to incumbent leaders; and lack of confidence in State
from financial institutions. It was concluded that majority of
the causes were anthrogenic, and while the effects touched on
stakeholders and the communities within which these projects
were to be implemented, the consequences touched the whole
economy as a result of the failures. It is recommended that
better management practice, political will and efficient
implementation of projects to avoid the huge rate of failures
and their attendant effects and consequences should be
encouraged in Nigeria.

Abstract:
Atrial fibrillation (AF) is the most common sustained arrhythmia
affecting humans. The initiation of AF may be caused by rapidly
firing foci, in the pulmonary vein (s). Although the atrial rate
is rapid, the ventricular response depends on atrioventricular
(AV) node conduction and the autonomic tone conductivity of AV
node. The aim of the present study was to compare to compare
effects of amiodarone and verapamil in prevention of atrial
fibrillation post coronary artery bypass graft in patients with
dilated left atrium. The study was carried out on 300patients
after approval of the medical ethical committee of Faculty of
Medicine, Ain Shams University and obtaining informed written
consent from all studied patients. We have (300) patients
undergoing CABG surgery ware included in the study with dilated
left atrium (more than 5mm in diameter). Divided into three
groups, Group (A): Included (100) patients, received IV
amiodarone in a dose of 300 mg I V loading dose followed by1200
mg /day by infusion. (50 mg/h), Group (B) included:
(100), patients received IV verapamil in dose of 0.6 mg/kg/h I V
by infusion, Group (C) included (100) patients as a
control group and received placebo in the form of equal volume
of normal saline 0.9% infusion. These medications were given by
IV infusion for 48 hours before surgery. We excluded patients
with chronic pre-existing AF or atrial flutter, previous
cardiac surgery, Patients on pacemaker, Patients on
antiarrythmic drugs and Contraindications to any of the
medications used in the study. In our study, the rate effects of
amiodarone a prevention of atrial fibrillation post coronary
artery bypass is 24%. On the other hand, success rate effects of
verapamil in prevention of atrial fibrillation post coronary
artery bypass is 38%. The results of our study showed the
superiority of amiodarone (p-value was significant =0.019)
in prevention of atrial fibrillation post coronary artery than
verapamil (p-value was significant =0.032). Also The
results of our study showed the superiority of amiodarone
group (A)
(p-value was significant =0.022)
in to decrease length of hospital stay
significant fewer
days than those in the
Verapamil group (B) and placebo group (C).

Effectiveness of Integrated
Functional Exercises Program on Some Specific Physical Variables
and the Performance Level of Some Movements in Modern Dance
Dr. Nadia
Saleh Ali
Abstract:
The current research aims to
designing an integrated functional exercises program and
identifying its effects on some specific physical qualities
(leg, back and abdominal muscles strength - leg, back and
abdominal power – spine and legs flexibility – both types of
balance – coordination – agility) and the performance level of
some movements (all types of falls and getting up – contraction
arch – free patterns of modern dance). The researcher used the
experimental approach (two-group design) with pre- and
post-measurements. The researcher purposefully chose (35) female
students of the third year – Faculty of Education (physical
education department) – University of Kuwait, who study the
modern expression curriculum. Five students were excluded due to
participation in sports teams. The researcher identified (8)
students as a pilot sample leaving only (22) students as a main
sample and divided them into two groups (11 students each).
Results indicated that:
1.
The
recommended training program with integrated functional
exercises had positive effects on all physical variables and the
performance level of some movements and free paterns in modern
dance.
2.
There
are statistically significant differences between the
experimental and control groups on all research variables in
favor of the experimental group.
3.
Variance percentages on all research variables were higher for
the experimental group compared with the control group.

Abstract: Background:
Abdominoplasty is one of the
most frequent aesthetic surgical procedures performed worldwide.
Postoperative seroma formation remains the most frequent
complication, also hematoma is considered to be a serious
complication that has a high reoperation rate. Objective:
To evaluate the effectiveness and efficiency of preserving
Scarpa’s Fascia in reducing postoperative complications during
abdominoplasty. Patients and Methods: This systematic
review and Meta-Analysis were conducted to estimate the pooled
benefits and adverse of preserving Scarpa‘s fascia during
abdominoplasty, highlight the evidence and quality of the
included studies and to share in modifying the current
guidelines. Results: The pooled estimate of the seven
included studies suggested that Scarpa’s fascia preservation was
associated with significantly reduced seromas relative to the
control group. However, Scarpa’s fascia preservation could not
significantly decrease the risk of hematoma or infection.
Compared with the control group, Scarpa‘s fascia preservation
was associated with a significantly reduced overall rate of
complications. Conclusion: Scarpa fascia preservation
could significantly reduce seroma, time until drain removal,
drain output, and hospital stay following abdominoplasty.

Abstract:
Water is an important element of
development and evolution. Egypt suffers from limited water
resources because it is located within the arid and semi-arid
zone. Agriculture is considered the largest consumer of water
resources in Egypt. Update the data of water budget for
agriculture at intervals is important to identify the total
water budget for agricultural crops especially when adding new
agricultural areas or using short duration varieties or spread
modern irrigation systems in larger areas. Current research aims
to calculate the water budget (WB) for Egyptian crops in the
2016/2017 winter crops and the 2017 season for summer, Nili and
perennial crops. CropWat8.0 model was used to calculate the
irrigation water requirements for the crops under study. In
addition, crop water productivity as well as the economic return
of land and water units were calculated. Results indicated that
total cropped area was 6.7 million hectare and its water budget
was 62.7 billion m3. The water budget of Egyptian
crops represents 78.4% of the total water resources in Egypt.
The highest crop water productivity (CWP) registered for carrot,
sugar beet, tomato, onion for winter crops; potato, cantaloupe,
watermelon for summer crops. The CWP values for the previous
crops exceeded 9 and 5 kg/m3 for winter and summer
crops, respectively. Regarding Nili and perennial crops, the
highest ones was found for tomato (5.05 kg/m3) and
sugarcane (4.77 kg/m3). The highest economic return
for the land and water units were recorded for strawberry, peas
(dry) and carrot. The economic return per land unit for the
three respective crops were 157810, 86467 and 62429 LE/ha, while
the economic return per irrigation water requirement (IWR) unit
were 18.51, 14.25, 14.00 LE/m3IWRin the
old lands; and 24.69, 19.00 and 18.66 LE/ m3
IWR
in the new lands.

Abstract:
In Nigeria, Annona muricata is locally being use as
source of medicine for curing various infections. This research
was aimed at determination of the potency of the leaves against
selected bacterial and fungal strains. The antibacterial and
antifungal activities of methanol, dichloromethane and n-butanol
extracts of Annona muricata leaves against selected
bacterial and fungi strains were examined. Methanol,
dichloromethane and n-butanol extracts of Annona muricata
leaves showed high inhibitory activities between (24-29 mm)
against Bacillus subtilis
(25-29mm) against Clostridium sporogenes, (25-29) against
Entrococcus faecalis (30-31) against Klebsiella
pneumonia
(26-31) against and (26-30) against Staphyloccus aureus.
The antifungal activities of methanol, dichloromethane and n-butanol
extracts of Annona muricata leaves showed broad
inhibition zones against the growth of Aspergillus flavus,
Candida albican, Fusarium oxysperium and Penicillium camemeri.
These study provide scientific information and justification
that support the local use Annona muricata leaves as
medicinal therapy and equally revealed Annona muricata
leaves as a major ingredient to bank on for the design of novel
antibiotics.

Abstract:
This research focused on
construction and testing of a dual-block mould machine that
produces high quality blocks for low cost housing. The
construction of a twin-block making machine was carried out as
an improvement on the manual production of single block locally
with a lot of ergonomic problems. Material mix is fed into the
machine, compressed and cranked up to remove the blocks from the
mould. The machine is powered manually by a lever arm. The
machine was evaluated for physical and mechanical properties
like bulk density, durability, and compressive strength. The
average bulk density for wet blocks was obtained to be 1927 (+
47.37) kg/m3 while the dry blocks gave 1838 (+
40.35) kg/m3. This figure is reported adequate for
most applications and can be improved by adjusting sand content
and moisture content of the mix. The average durability obtained
(81 + 6.56%) is a clear indication that the produced
blocks will last longer. Also, the wet compressive strength was
2.8N/mm2 while the dry compressive strength was 8.1
N/mm2, comparison of the values with Nigerian
standards indicate that the produced blocks conforms with
acceptable values.

Abstract:
A major public health challenge that Nigeria faces as a country
is the scourge of infectious diseases. Screening for infectious
diseases help to detect and identify suspected cases who could
be potential source of infections and possible challenge to the
public. The emergence of HIV brought an additional pressure on
the health sector as a result of increased occurrence of many
infections. Among such infections are Hepatitis B virus (HBV),
and syphilis which are recognised co-factors for increased risk
of HIV transmission and acquisition. The study aimed at
determining the prevalence of HBV, HIV and syphilis infections
among newly admitted students of the University of Port
Harcourt. A total of 500 blood samples were screened for the
presence of HBsAG and HIV but 315 for syphilis antibodies using
different types of Rapid Diagnostic Test kits. Study
participants were made up of 229 (45.8%) males and 271 (54.2%)
females in the age range of 15->29 years. Age group 15-19 had
the highest frequency of 265 (53%) while the lowest frequency
was in the >29 years group with 7 (1.4%). Obtained prevalence of
HBsAG was 7 (1.4%), HIV 3 (0.6%), and syphilis 5 (1.6%). Highest
number of viral infections was found in 20-24 age group: (HIV
3/3 (100%) and HBV 6/7 (85.7%). Syphilis infection was found
only among the males while the viral infections were found more
in the females. Even though study suggests a low prevalence of
these infections, there is need for increased awareness of safe
sex practices since sexual route is the commonest route of
transmission, also need for adequate treatment for positive
cases to prevent the spread to the general university
population. Voluntary screening for these infections as well as
inclusion of vaccination against HBV as part of the medical
exercise for registration in the university is advocated.

Abstract: This study
investigates the stream sediments of South Wadi Ras Abda area,
northern eastern desert, located approximately 20 km southwest
of Safaga City on the Red Sea. The area is primarily covered by
subduction-related older granites intruded by
intraplate-magmatism of younger gabbro. These two rock types are
cutting by acidic dykes followed by intrusion of microgranite
and emplacement of basic dykes. The raw sample was subjected to
screening to remove the sizes over +2mm then sand size sample
was concentrated by wet tabling which separates the heavy
minerals from the other gangue minerals, and the concentration
of heavy minerals was subjected to magnetic separation to
separate magnetite. Where all samples undergo heavy liquid
separation using bromoform and methylene iodide solutions and
the heavy fractions were subjected to magnetic separation with
using Isodynamic magnetic separation to facilate the process of
identification and separation of each individual mineral by
binocular stereo-microscope and then studied under scanning
environmental microscope. The grain size distribution of the
stream sediments relevant that the sand size is the main
component, and it ranges from (57.69% - 97.68%) with an average
(81.62 %). The grain size distribution of magnetite of the study
area is unimodal with medium sand size class, which constitutes
more than 51.35 wt% of the particles, then the fine sand size
class contains 32.54 wt%. The total magnetite content in the
industrial scale was 1.33%, where the total magnetite content in
the laboratory scale fluctuates between natural (0.17 % and
38.54%) with a general average of about 2.07%.

Abstract: The
article presents the criteria
of the
assessment of the
effectiveness of the process of preparing students for
pedagogical activity. It is advisable to consider the process of
preparation for the pedagogical activity of students in the
direction of professional education, as a system whose
components are theoretical and practical classes in higher
educational institutions on pedagogical disciplines. Criteria
and indicators for assessing the effectiveness of the
preparatory processes for teaching activities of students in the
direction of professional education are determined on the basis
of the qualification requirements of bachelors in the direction
of professional education "Informatics and Information
Technologies", curricula, scientific and methodological
literature, teacher’s work experience, and also on the basis of
research results. The criteria reflect the essence of the
development of the pedagogical process and the subjects of the
pedagogical process. The indicators are inherent dynamism,
interconnectedness and interdependence. Therefore, the criteria
for evaluating the effectiveness of the processes of preparation
for teaching activities of students require the selection of the
necessary indicators. On the basis of criteria and indicators,
indicators for assessing the effectiveness of the process of
preparation for the pedagogical activity of students in the
direction of professional education are determined.
