The irregular atmospheric situations that happened in Syria in the last
few years, caused unusual rainfalls that badly affected the environment
they appeared especially in the interior regions of Syria. They are called
the local rainfalls in speci
al regions, either in spring when it becomes hot,
or in autumn before it becomes cold. The unexpected rainfalls that
happened in May in 2007, were exceptional because it rained heavily for
along time.
This event is caused by many atmospheric factors and local reasons.
The results were great floods and inundation which caused losses in
properties and souls and that led to soil Erosion.
This paper discusses the poetic patterns and psychological which are
conveyed by imagery in modern Poetry Divan in Yemen, and which
Poets used to direct their meaning.
Images in poets divans varied between simile, sensational images and
metaphori
cal prosopopoeia, embodiment, "symbolism" the images that
displays poet mentality.
The psychological functions achieved by rhetorical uses create a
bridge of understanding with audience. They show a gap in the relation
between the images and psychological denotations, and they carry a
plenty of contemporary significance in their symbols, these pictures will
remain in the interior constructing context which came from undulation
of the psychological movement whether these images were sensational,
mental or symbolic. So employing the psychological rhetoric and is
denotation by the poets is confined to articulation only, but exceeds to the
inspirations & psychological undulation which addresses the conscience,
therefore the poets did not use certain rhetoric pattern or type of images
move a the others, but they widened the use of rhetoric so as to able to
deal with reality in all its facts and forms, and explain their attitudes and
feeling towards this reality.
The goal of this research is to study the expression of epidermal and
transforming growth factor receptor in normal human bone marrow (BM)
cell, and in leukemia ( myeloid and lymphatic leukemia ) which promoted
the research for the function of EGF
R receptors in the development and
growth of BM cells and for malignancies expressing of the EGFR as
potential therapeutic targets in blood cell malignant diseases.
The Bcl-2 family of proteins has been implicated as a necessary factor in the
death caused by a large number of different agents of a wide variety of cell
types. Cystine is a precursor for the biosynthesis of the intracellular Thiol,
(glutathione)
GSH.
The mechanism by which Bcl-2 resist cystine deprivation induced apoptosis
was investigated in hepatocyte Hepz/Bcl-2 and Hepz/pEF cell lines.
This research aims to study and design a single mode optical fiber using simulation,
with a core and glass cladding, and also helps in ensuring the efficiency to use the optical
fiber designed within the broading window C-Band,and that these resear
ches and studies
tries to use this window. This research also shares to set the light on the Numerical
Programmes and Simulation used now in studying and designing these optical fibers. At
first we used the programOptifiberto reach the confidence of Sellmeier equation for the
fiber core, and this completed by using the finite element method solving the equation of
propagation the electric field and finding its 3-D distribution, using the famous simulating
COMSOLMultiphysics. This completed by putting the program MATLAB to reach the
two equation: the total dispersion and attenuation for the designed optical fiber.
Several protocols for DNA extraction from leaves of pepper Capsicum annuum
L. were evaluated to detect Begomoviruses. The extraction
methods comparison were based on DNA quantity and quality. The
DNA concentration absorbance for the evaluation of DNA concentration and contamination
were measured using spectrophotometer.
The purpose of the research was to identify the level of reasoning
thinking in a sample of students in the sixth grade for the academic
year 2016-2017. The effect of the sex variable (male and female)
was defined on their levels.
In this research, the concentration of thiocyanate ion in serum has been investigated,
thiocyanate has negative effects on human body when it increasses higher than specific
limit, this ion is produced by the metabolism of cyanide which exist in ci
garette smoke.
Spectrophotometric method has been used in the visible range at λ=460 nm, the formation
of the complex between thiocyanate and reagent Ferric chloride (FeCl3) have been made in
an ideal parameters such as temperature 25 ºC, time=15 min, pH=4.4, volume of citrate
buffer=0.75 ml, volume of reagent (FeCl3) =1 ml and concentration of reagent = 0.02
mg/ml.
The selected method showed good accuracy and precision, the accuracy of the method has
been validated with R=99.3%, and the precision of relative standard deviation was
(RSD<=1.149 % .
The concentration of thiocyanate has been studied in a sample of 240 non-smokers’ and in
a sample of 240 smokers’, these samples have been divided into different age groups.
The maximum concentration of thiocyanate was 89.49 μmol/L in the fourth group (>50
years) of the non-smokers’, and the maximum concentration of thiocyanate was 190.27
μmol/L in the fourth group (>50 years) of the smokers’. The maximum concentration of
thiocyanate was 91.647 μmol/L in the non-smokers’ males and 86.623 μmol/L for the nonsmokers’
females, whereas the concentration of thiocyanate was 204.53 μmol/L in the
male smokers’ and 167.33 μmol/L in the female smokers’.
Selenium is an essential nutritional mineral, and selenium deficiency diseases are known in medical literature. Studies have shown that selenium intake in high doses is toxic in humans. Selenium is widely distributed in nature and due to the importan
ce of selenium and its compounds in industrial applications; several analytical techniques have been reported to estimate selenium. In this study the optimal conditions for the formation of selenium complex with NEDA reagent will be studied and used for the control of selenium microcapsules, a method that is characterized by being rapid, sensitive and selective. The optical spectrophotometric method was used in the visible field at 540 nm wavelength to determine the complex between the selenium ion and the NEDA reagent under optimal conditions for complex formation namely temperature 50℃, time min t = 240, added reagent volume V=4ml, and reagent concentration 1%. This method showed good accuracy and correctness, as the method's validity was achieved through the relative percentage yield (R = 99.68%), while the accuracy of the method was achieved through the low value of the standard deviation (SD≤) (1.172) and thus the percentage relative standard deviation (RSD≤) (1.725). Selenium microcapsules were prepared, with an entrapment efficiency of 36% at a concentration of 3% for alginate and 1% while the entrapment efficiency rose to 51.2% at a concentration of 2% for calcium chloride.
