The study of textural characteristics of marine sediments is very important to
understand the evolution and distribution of coastal deposits, the hydrodynamic conditions
of the depositional environments, and seasonal changes along the coasts, by co
llecting
samples during seasonal periods. Due to the lake of sach studies in our coast, aset of 14
samples has been collected from superficial sediments of Ras Ben Hane beache during the
beriod that range between 10/2015 and 6/2016. the grain size parameters (Mean,
Standarddiviation, Skewness, and Kurtosis) showed that the grains are coarse to very
coarse in their size, moderately to poorly sorted, coarse to strongly coarse skewed, and
mesokurtic to platykurtic. Based on the CM patterns, the samples fall in rolling fields,
while their morphological study showed that most of grains are subrounded.these
parameters confirm that the sediments were deposited under high energy conditions, as the
coarse and very coarse grains need high energy to more by rolling on the sea bed. while the
subrounded shape of the grains indicates that the grains are transported for along distance
befor they settels down in their site of deposition.
In this paper the Einstein's transition coefficients are introduced,
Their ratios are found by setting the transitions from one state of an
atom to be in balance with the reverse transitions between the same
two states in thermal equilibrium.
This paper presents the application of electromagnetic wave
scattering in human cervical cells. Particularly, studying the effect
of morphological and physiological alterations on the properties of
light scattering. Tissue alterations are caused b

dysplastic cervical cells and its internal structures.
The audio-visual speech recognition systems that rely on speech and
movement of the lips of the speaker of the most important speech
recognition systems. Many different techniques have developed in
terms of the methods used in the feature extracti
on and classification
methods.
Research proposes the establishment of a system to identify isolated
words based audio features extracted from videos pronunciations of
words in Arabic in an environment free of noise, and then add the
energy and Temporal derivative components in extracting features of
the method Mel Frequency Cepstral Coefficient (MFCC) stage.
في عام 1895 اكتشف الفيزيائي Roentgen الأشعة السينية (x-rays) وفي عام 1912قام الفيزيائيون Von Laue و Friedrich و Knipping بتسليط الأشعة السينية على التوتياء ودرسوا البنية البلورية للتوتياء
Decision makers uses several quantitative models for the selection
of suitable investment alternatives, high yielding and high
competitive ones, and what the most needed to the Syrian economy,
especially in the reconstruction phase, is to test the
se models and
study their credibility in leading the investment process, and from
this point this research is studying the internal rate of return model
in the evaluation of investments, which draws the importance and
the need for professionals and investment decision-makers reliance
on this indicator in their studies and analysis, as well as a range of
models of different quantity, in order to obtain top payoff of
investment alternatives available to them and to achieve
competitiveness for their projects and businesses.
In this paper: the Daubechies families of wavelets Daubechies
and multi resolution analysis based on Fast Fourier Transform
algorithm (FWT) have been applied to solve some differential
equations with Boundary Value.

The transformation of coordinates between the global coordinate system yield
ellipsoid WGS84 (World Geodetic System 1984) and the local coordinate system yield
ellipsoid Clark1880 in different regions of Syria, is the essential step in the effectiv
e use of
GNSS (Global Navigation Satellite Systems) surveying techniques in Syria, and the
transformation occurs with 3D transformation between one ellipsoid and another, or 2D
transformation directly between two planar. The transformation must be understood,
analyzed and tested. The research is about the accuracy of the 2D transformation in small
area to give coordinates can be directly used in different surveying and engineering works,
and about studying the common points number and their distribution effect on
transformation accuracy, and conclude that the biggest effect on transformation accuracy is
for the common points distribution.
The research was conducted in the ornamental plants laboratory, Faculty of
Agriculture, to determine the best seed germination conditions of Sophora japonica and S.
secundiflora. Different seed pre-treatments (cold ater (6oC) and warm water (50oC)
immersing, Citric acid (2%) and Sulphoric acid (25, 50%) stratification) were
experimented. The effect of different culture mediums and sowing times were also
investigated.
The results indicated that the chemical pre-treatments represented the highest relative
germination rates compared to the physical pre-tretments. Among the physical pretreatment,
the seed immersed in hot water for 2h showed the highest germination
percentage (38,6 – 30%) for S. japonica and S. secundiflora respectively. While, the seed
treated with sulphoric acid represented the best germination percentage for the tow species
(58,3 – 63,6%). Nevertheless, the increase of the sulphoric acid concentration had a
negative impact on survival plantlet rates for the tow species, specially for S. japonica.
The results showed that the seed sowing in sand with soil and organic mature (1:1:1)
medium realized the best germination percentage for the tow studied species.
