Research aimed to reveal the relationship between PTSD and irrational thoughts in
a sample of Ba'ath University students, Consisted the research sample of (509) male and
female students of the first year of the Faculty of Education - Baath Universi
ty and from
difference specialties, Use the two researchers a list of traumatic experiences, and test of
PTSD, prepared by Hanna, 2016 and test irrational beliefs prepared by Suleiman alryhany
the two test are reliable and had a good degree of validity and reliability
The results showed
1-. Post-traumatic stress disorder prevalence among the study sample (48,85%)
2- the prevalence of irrational ideas among the study sample (37.5%).3 - There is
statistical significance correlational relationships between PTSD
and irrational thoughts in the study sample.
4. There are statistically significant differences between students who saw traumatic
experience and students who experienced traumatic experience in PTSD and the difference
for students who saw the traumatic experience.
5- There are no statistical significance differences between students who saw
shocking experience and students who have experienced traumatic experience in irrational
ideas.
This research presents an empirical relationship between modulus
of elasticity with compressive strength concrete that is prepeard
from localized materials and containing several perecentages of
natural pozzolan (0 ,10 ,15, 20)% , also for tow cem
ent quantity
(350 ,400 ) Kg/m3 and for tow ages(28 ,90 ) day .Then comparing
the experimentally obtained result with the mechanical properties
calculated using the recommend relationship from the various
design codes. A new empirical relationship between elastic
modulus, and compressive strength for concrete containing natural
pozzolan is proposed.
The study of the effect of the common addition of Syrian Clay
and magnesium oxides on the specifications of the resulting
cement stone and specifically its effect on the elasticity of the
resulting stone.
This study aimed to evaluate the fracture resistance of the E
glass Fiber Reinforced Composite when used to repair two different
kinds of dental porcelain.
Considering the increasing importance of stereo image compression and Fractal
geometry becoming one of the most important fields of modern science ,we applied fractal
image compression based on quadtree portioning method and global search algorithm
, on
a group of stereo image pairs . As the stereo image consists of two planar images , left and
right .Both the left image ( reference image ) and the disparity map between left and right
images , were compressed using fractal compression . We applied both block matching
algorithm and Semi Global Method (SGM)to obtain the disparity map.
The left image and the depth map were reconstructed using fractal decompression
while the right image (target image ) was reconstructed using the reconstructed left image ,
disparity map and the error image between the original right image and the reconstructed
right image that was build from the left image and the disparity map .
The results were evaluated using quality objective measures which are MSE (Mean
Square Error ) and PSNR (Peak Signal to Noise Ratio) and efficiency objective measures
which are CR(Compression Ratio) and compression time . The results were compared
with JPEG compression of stereo pairs based on Discrete Cosine Transform DCT and
JPEG2000 compression of stereo pairs on stereo image based on Discrete Wavelet
Transform DWT .
This research focuses on identifying spatial and temporal variationsof the carbon
dioxide system in the surface seawater of Tartouscityduring the period betweenspring and
summer 2015.In Addition to the extent influenced by some hydrological propert
ies of
water (temperature and salinity) and the impact all of this on the pH of marine water
values.
The results showed low partial pressure of the carbon dioxide in seawaters (PCO2
sea)
in the summercompared with spring, which is reflected on the air-sea flux values (FCO2),
where CO2 released from surface seawater to the air in summer and incontradiction of that
in the spring (0.0632mmol /m²/ day and -0.0715 mmol /m²/day, respectively). In spring,
low temperature and salinity of the water (22.707-22.727C and 37.605-37.765‰
respectively), in addition to increased biological activity contributed in increasing the
absorption of CO2 from the water.These leading to a decrease PCO2
sea (409.0- 429.5μatm)
associated with low concentrations of all of the total inorganic carbon (2229.5-
2242.5μmol/kg) and total alkalinity (2588.873-2590.9μmol/kg). and as a result the surface
sea waters become a reservoir of dioxide carbon atmospheric.
In the summer, the rise in temperature and salinity of surface seawater (28.85-
29.60Cand38.15-38.60‰, respectively) and reduced biological activity all contributed to
the decrease dissolved CO2 values and increase of PCO2
sea(437.5 - 453.5μatm)
associated with increasing concentrations of each of the total inorganic carbon
(2267.9 - 2296.0μmol/kg) and total alkalinity (2739.6 -2741.2μmol/kg).In this way the
surface sea water is source of carbon dioxide to the atmosphere.
Aim: to study the prevalence of glaucomatous injury in pseudoexfoliation patients,
and the relation of these injuries with IOP values.
Methods: 75 PXS eyes were compared with 75 age matched control eyes, and so 21
unilateral PXS patients were stud
ied by comparing their two eyes. The study contained
ONH study with Heidelberg Retina Tomograph (HRT), and mean and range of IOP values.
Results: ONH parameters which were compared between patients and controls
included: disk area, rim area, cup area, mean RNFL thickness, vertical cup\disk ratio,
MRA result, and GPS result. The difference was significant in all these parameters
between patients and controls, also it was significant in mean IOP and its fluctuation. For
unilateral PXS patients, no statistically significant difference was found in ONH
parameters between the two eyes, but there was in IOP mean and range.
Conclusion: PXS eyes are at high risk for developing glaucomatous optic nerve
injuries, which were more probable with raised IOP mean and range; the risk also involved
the other normal eye in unilateral PXS, certaining the systemating nature of pseudo
exfoliation disease.
In this research, we have derived an analytical equation gives
dependency of the total gas pressure to operation time for halogen
self-quenched GM counter tubes and organic vapor or gas selfquenched
GM counter tubes. This equation indicates that t
he gas
pressure exponentially decreases as the operation time increases, at
constant temperature of tube and constant activity that this tube
exposed to.
This research carries how to do steel pipelines defects repair process by a simple and
easy way. At first the region that surrounds the defect is cleaned then the epoxy material is
put over the defect after mixing the resin with the hardener well.
Epoxy layer dimensions
depend on the defect dimensions that exists in the pipe. After that, the specimen is released
for a period of time to obtain the setting process. Several types of epoxy were used for
preparing series of specimens, which were tested on the pressure set up to estimate the
efficiency of this way in the repair, and knowing the pressure values that epoxy layer can
carry. A pipe of three holes their radius are equal, was treated by using ALTECO QUICK
EPOXY STEEL and the pressure gauge recorded many values that reached 18 bar. The
curve, that represents the relationship between the pressure which the epoxy layer carried
and its surface area, was drawn. It is found that the most effect factor in the repair process
is the specimen preparing and the thickness of the epoxy layer.
