Abstract:
This review work was conducted to explore the likely impacts of
climate change on livestock production and productivity and
different adaptation strategies in Ethiopia. National average
temperature has increased by 10 c since the 1960s.
Most of the livestock owners in the country perceive there is a
climate change impacts on Livestock production and productivity.
The major effects of climate change on livestock production
include feed shortage, shortage of water, livestock genetic
resources loss, reduced productivity, and decreased mature
weight and/or longer time to reach mature weight in their order
of importance. Higher temperatures resulting from climate change
may increase the rate of development of certain pathogens or
parasites that have one or more life cycle stages outside their
animal host. Furthermore, the spatial distribution and
availability of pasture and water are highly dependent on the
pattern and availability of rainfall. Shortage of feed and water
contribute to reduced productivity and reproductive performance
of livestock. This includes slow growth rate of animals, loss of
body condition, reduced milk production and poor reproductive
performance in mature animals. Draught oxen that are emaciated
and in poor body condition cannot provide adequate draught power
for plowing, and thus affects crop cultivation. Bush
encroachment as well as population pressure lead to diminishing
availability of good pasture and hence to a decline in the total
number of animals. Different adaptation options are followed by
Livestock owners, such as Conservation of feed, out-migration of
some household members to earn additional income, destocking,
settlement and intensification of livestock production,
undertaking supplementary income generating activities and
awareness creation on the factors affecting climate change.

Abstract:
Plants in their natural environment are exposed to various
abiotic stresses such as drought, salinity, extreme
temperatures. Drought severely impairs plant growth and
development and hampers performance of plants. It inhibits many
metabolic processes and eventually constraints plant growth. We
investigated whether the role of AMF can be major factor in
improving the efficiency of Cenchrus ciliaris growth
under different field capacities. Results showed that AMF
inoculated seedlings of C. ciliaris had significantly
higher growth at low field capacities than those of Non-AMF
inoculated plants. It is concluded that AMF fungi may play a
positive role under drought conditions and helps in improving
the efficiency of the C. ciliaris to grown under
drastic adverse abiotic drought conditions.

Abstract: Background: The aim of our
study was to assess of tracheal intubation by different doses of
propofol preceded by fentanyl for successful tracheal intubation
and to see its effectiveness in blunting pressors response in
children aged 2-12 years. Methods: This prospective, blind,
randomized study was conducted on 60 ASA grade I and II
children, between 2 and 12 years undergoing elective surgery who
were divided into three groups. The children received different
doses of propofol (group I, 2.5 mg/kg; group II, 3.0 mg/kg; and
group III, 3.5 mg/kg) preceded by a fixed dose of fentanyl (2
µg/kg) 5 min earlier. The tracheal intubating conditions were
graded based on scoring system devised by Helbo-Hensen et al.
with Steyn modification which includes five criteria; ease of
laryngoscopy, degree of coughing, position of vocal cords, jaw
relaxation, and limb movement and graded on a 4-point scale.
Heart rate (HR) and mean arterial pressure (MAP) changes were
also noted. Results: Tracheal intubating conditions were
acceptable in 25% of the patients in group I, while
significantly higher (P<0.001) in group II (80%) and in group
III (90%). The pressor response was not effectively blunted in
group I (increases in HR), while effectively blunted in groups
II and III. A fall in hemodynamic was seen in group III
indicated by a decrease in MAP and HR. No airway complications
were noted. Conclusions: Propofol 3 mg/kg (group II) preceded by
fentanyl 2 µg/kg is the safest option dose combination in our
study. It provides acceptable intubating conditions in 80%
patients, blunts pressor response to intubation without
significant cardiovascular depression.

Abstract: This research aims to
identify the effectiveness of balance exercises on restoring the
stability and functional efficiency of ankle joint. The
researcher used the experimental approach (two-group design)
with pre- and post-measurements. Participants (n=10) were
purposefully chosen from soccer players of Al-Qadesia Sports
Club – Kuwait. They were divided into two equivalent groups. The
experimental group (n=5) contained players with functional
disorder and instability of ankle joint (right foot) because of
repeated ankle sprain injury. The control group (n=5) included
players who were free of any ankle injuries. Results indicated
that: - The recommended balance exercises improved stability of
the injured ankle joint. - The recommended balance exercises
improved function of the injured ankle joint. - The recommended
balance exercises fully rehabilitated the injured ankle joint. -
The recommended balance exercises improved confidence and
decreased fears of lack of stability among injured athletes. -
The recommended balance exercises improved proprioceptors
function of the injured ankle joint.

Abstract: ‘Ogi’ is a fermented maize
product which is commonly used as weaning food for children in
Nigeria. However, there is dearth of knowledge on the possible
aflatoxin contamination of many of such indigenous maize
products due to commonly associated fungi and possible control
measures. This study was therefore conducted to investigate the
fungal and aflatoxin composition of stored Ogi powder and the
effect of ginger fortification in relation to the shelf life of
the product. Ogi samples were prepared in the laboratory and
fortified with different concentrations of ginger at 5 different
batches namely: Control (unfortified Ogi), TreatmentT1 (97.5%
Ogi+ 2.5% ginger), Treatment T2 (95% Ogi + 5% ginger), Treatment
T3 (92.5% Ogi+7.5% ginger) and TreatmentT4 (90% Ogi+ 10%
ginger). They were later dried into powder and stored for eight
weeks. The nutrient and aflatoxin contents (AFB1, AFB2, AFG1 and
AFG2) of the samples were analyzed before and after storage
using Thin Layer Chromatography. Generally, the pH and the
nutrient contents such as crude protein, crude fiber and crude
fat of the samples reduced with the increased storage time but
increased with the ginger concentrations. The treatments also
improved the sensory attributes as T2 was the most generally
accepted sample after 8 week of storage. Result obtained also
showed that different fungi are associated with the samples
which increased with the storage time, the isolated
aflatoxigenic fungi includes Aspergillus niger, A. flavus, A.
penicilloides A. tamarii, A. fumigatus and A. ellipticus while
others belongs to Fusarium, Penicillium, Saccharomyces, Rhizopus,
Trichoderma and Alternaria species. In addition, the control had
the highest fungal load (5.33-12.00 cfu/mL) and aflatoxin
contents but they were significantly reduced in T1-T4,
respectively. The aflatoxin contents of the samples increased
with the storage time but none was higher than the tolerance
limit. Consumers are therefore encouraged to consider using
ginger as additive in preparing Ogi especially at 5 %
concentration to improve the taste and reduce the possible
aflatoxin contamination.

Abstract:
The distribution and abundance of bovine tick species in Bambasi
districted was studied from October 2017 to November 2017. Adult
tick was collected from eight sites a total of 447 local cattle
which were under extensive management system. A total of 3566
adult ticks collected from half body part times two were
identified, in which two species belong to Amblyomma, one
species belong to genus of Boophilus, two species Rhipicephalus
and one species belong to genus Hyaloma, of all the total tick
collections, boophylus, Amblyomma, Hyalomma and Rhipicephlus
constituted 40.8%, 39.3%, 0.30% and 37.82% respectively. The
tick species encountered were B. decoloratus (40.8%), A.
variegatum (38.4%) R. evertsi-evertsi (24.02%), R.praetextatus
(13.8%) A. cohaerens
(0.09%) and H.m, rufipes (0.30). The burden of ticks on
cattle by their age group (1<year, 1-3 year and >3 year had
statistically significant difference (p<0.05), (mean =1.7 tick
/head, mean=7.8 tick/head/mean =16.9 tick/head) respectively in
the study area. The study result indicates that the favorable
predilection sits of Boophilus species are dewlap, back
and hoof, Amblyoma species are found most of the time
ventral body part and hoof, because of long mouth part. Adult
R. evertsi–evertsi had a strong predilection site is under
tail as well as ano-vulav areas. The body condition also
indicates high infestation in poor body condition and less
infestation in good body condition the burden of tick in body
condition (poor, medium and good has statically significance
(p<0.05), (mean=12.9 tick/head, mean=8.7tick/head,
mean=4.1tick/head) respectively in the study area. In finalize
tick should be managed at the level that they cause no more
economic loss; since there is no single method that adequately
control the problem of ticks and tick borne diseases,
combination of available techniques to produce an integrated
system of tick management is necessary; further studies on the
distribution pattern of tick species and their epidemiology are
necessary for the continuous understanding of control strategies
thereby bringing the tick number on livestock to numbers that
are more manageable.

Abstract: Evapotranspiration is one of
the important factors that knowing the exact amount, for
determining water requirements and irrigation system design is
essential. One way to determine evapotranspiration using
experimental models, but to use them in every place must first
be evaluated. For this purpose, the study compared the results
of 18 models evapotranspiration with drainage Lysimeter and the
Penman-Monteith (FAO56) was evaluated. This study was conducted
in Hangar research station of the University of Mohagheghe
Ardabili, Ardabil. For this purpose grass were planted in 3
Lysimeter and around the Lysimeter. Grass evapotranspiration
measured by volumetric Lysimeter based on water balance equation
components (input and output water volume, save moisture and
evapotranspiration), was estimated. To estimate reference
evapotranspiration 18 models, including models such as
temperature, radiation, and the combination was chosen. The
meteorological synoptic station of Ardabil was used to prepare
the information needed to model. Besides the results of
Lysimeter, evapotranspiration obtained by the FAO Penman-Monteith
model also was used as a reference for comparing the performance
model. Evapotranspiration estimation models using statistical
indices, root mean square error (RMSE), mean absolute error
(MAE), the estimated margin of error (PE), the ratio (MR) and
spearman’s rho coefficient is calculated as follows to cross
they were evaluated. The results showed that for all models,
high dispersion of points around the line one to one, or answer
them consistent with the results of Lysimeter answer is not
good. Moreover, some of these models overestimated and
underestimated some of them to calculate evapotranspiration.
Using statistical indicators may be compared with the results of
Lysimeter, at the most proper research models, respectively
Blaney Cradle, Ravazzani and the Rn and the weakest models
respectively Irmak and Valiantzas. Overall fit the model results
against the results of the FAO Penman-Monteith model compared to
its results compared to the results of Lysimeter, was more
suitable. Also according to the statistical criteria in this
study, the FAO Penman-Monteith model, the most appropriate
models were Turk, Berti and the Trajkovic, and the weakest
models, modified Hargreaves-Samani, Irmak and Scandal were
determined. In both assessments methods (Lysimeter and FAO
Penman-Monteith model) were not the same in determining our
study was the weakest model in place. That is, both methods
together, Irmak models (2003) and models Valiantzas (2013) had
the weakest results. In other words, although the sum of the two
methods compares the most appropriate models cannot be
identified with certainty, but the weakest model was determined.

Abstract:
Aim of the study:
The evaluation of Surface Durability
of newly developed conventional glass ionomer cement modified by
chitosan. Materials and
Methods:
A total of 380 cement disks were prepared to represent 4 groups;
90 disks for each.
Conventional Glass Ionomercement disks; control group, (Group 1)
and
other groups' disks were modified
by adding chitosan solution to poly carboxylic acid liquid of GIC
(v/v)
in ratio of 0.25, 0.5 and 0.75/1 to represent
Groups 2,
3 and 4 respectively. The disks of each group were subdivided
into 9 subgroups;
n=10.
Working and setting time of different groups were measured.
Then, water sorption and solubility were calculated after
storage in distilled water (37ºC)
at time intervals
72 and 168 hrs. As well, micro-hardness and surface roughness
changes after different storage time intervals 24, 72 and 168
hrs for each investigated groups were measured. Surface
chemistry was analyzed by XRD. Results:
Despite the highest
significant
prolonged
working time and setting time was recorded by Group 1
(4.76±0.41,10.79±.43min), it was insignificantly decreased in
the other investigated groups.
The
highest water sorption was recorded by Group4 after 72 and 168
hrs (105±7.9, 41.1±29.4 μg/mm3), but the least values
were recorded by Group 1 (61.8±11.5, μg/mm3). Also, the highest
water solubility was recorded by Group 4 after168hrs
(196.27±58.6μg/mm3) whereas Group 2recorded the least
one (150.7±38.3 μg/mm3). Regarding the
micro-hardness, Groups 2,3 & 4 revealed lower hardness value
than Group 1 after 24 hrs (50.8±2, 45.3±5.38,37.1±8.76
and
54.9±2.9VHN). Meanwhile,
Groups2 and 4 recorded the highest significant surface roughness
(3.2±0.99 and 2.9±0.94 µm).
The XRD chemical analysisreleaved that the surface of the
samples composed mainly of aluminum silicon and sodium silicon
fluoride.
Conclusions:1)
Increasing chitosan amount decreased both working and setting
time of conventional GIC. 2) Increasing percentage of chitosan
was adversely affect water sorption and water solubility; in
addition to, surface hardness. 3) Durability of GIC was
adversely affected by chitosan addition.

Abstract:
The reference
evapotranspiration (ET0), is one of the important components of
the hydrological cycle, which needs to be precisely estimated
for optimal water resources management. The present study
aim to evaluation of six different methods to predict reference
crop evapotranspiration based on air temperature in 11 stations
of Khuzestan province in Iran. For this reason, the monthly
weather data of the study stations was used during the
statistical period 1996-1996.
The results of the methods were compared with the result of the
FAO Penman –
Monteith method (PMF-56) and in order to evaluate the
performance of the methods, were used statistical indices of R2

Abstract:
Beta binomial Model is a standard choice for modeling multiple
sequences of binary responses. This research was carried out
based on the efficiency and consistency of Beta-binomial Model (BBM)
in tracking and forecasting purchasing pattern of consumers of
Soft drink using secondary data collected from whole sales
outlet of a standard bottling Company, The model (BBM) as
compared to binomial model (BM) was fitted to the data. Akaike
Criterion, Bayesian Criterion and QUOTE goodness of
fit were used to establish the efficiency and flexibility of BBM
over BM in predicting the customers’ purchasing pattern. The
analysis shows that Beta-Binomial Model fitted better coupled
with it low standard error in predicting future purchasing when
compared with Binomial Model. We can therefore say that the
predictive efficiency of this model is high. The usefulness of
BBM as illustrated using real data depicts that it can be relied
on for consistent planning and decision making.
