Administrative responsibility is a real
guarantee of respecting environmental laws. If the
administration aims to protect the environment and
create sustainable development, we should help it and
expand its responsibility. Development should not
take
priority over the environment and resources’ health.
The aim of This study was to identify the skeletal and dentoalveolar
components in Syrian adult subjects whom have an anterior open
bite by comparison with the normal occlusion subjects.
This study showed elongation of upper and lower incisors,
o
f upper molar height and increasing of anterior facial increasing
height (P<0.05) in anterior open bite group compared with natural
occlusion group .
Backlash has been studied in this project. Backlash is the clearance between mating
components. A state of the art has been done, and it includes: methods of measuring, modeling
and compensating the backlash. There are mechanical methods to compens
ate the
backlash but we concentrated on the control techniques, they have been studied and DUAL
MOTOR CONTROL method was chosen for this work.
Pulses suffer from changes in time and space when it propagates through matter, like
the positive Group Velocity Dispersion (GVD) which increases the pulse duration and
disperses its components ,this appears a2s a result of the second derivative of phase with
respect to frequency. We show in this article the possibility of a compensation way to
shorten the pulse duration based on negative GVD.
Studying is showed that the amount of exchanging information in the network
surprisingly grows due to developing new communication services. But, when data rates
increase the optical system performance degrades due to dispersion, which was taken in
to
account in this research. Where as the reduction of dispersion losses is important in optical
networks. Fiber Bragg Grating (FBG) is one of the most important components of optical
communication systems, and one of the effective methods used for this goal.
This article tests the effect of using FBG as dispersion compensator in optical
communication systems, where we simulate optical communication system using FBG.
And study the effect of Erbium Doped Fiber Amplifier (EDFA) and FBG and fiber optic
parameters on this system performance, and it has been finding the best values of the
system parameters. Which the simulation model depended on two Optisystem7 and Matlab
software. We evaluate performance through eye diagram and two factors Q, Bit Error Rate
(BER).
Insurance sector is considered one of the most important financial services sectors around the world, because accompanies economical activities , contributes to their support , and maintains their stability , the important social role of insurance ac
tivity is highlighted through job vacancies provided ,or through its contribution in the social stability .
Our study aims to review the main important of government insurance on vehicles in Syria through analytical study the rate of compensation of such branch in Syrian Insurance Company since it is the company that practices government insurance, in addition to spot the light on insurance effect on the total business of such company from 2007 to 2012
The study can conclude that government insurance sector of vehicles in Syria constitutes the main share of business volume of Syrian Insurance Company. This indicates the weakness of other insurance branches, in addition to the emergence of the impact of political security, economic crisis experienced by Syria on such sector starting from the decrease of insurance premiums to the increase of vehicles accidents number which led to the increase of the paid compensation installments and company’s reserves which caused unforeseen losses to the company.
This research aims to introduce the species of insurance located in the Syrian market,
and compare them in terms of return and risk resulting from each of them, in addition to
trying to develop a model to measure the size of the development of the
insurance sector in
the Syrian market, using multivariate equations. Where the study showed that there is a
difference between the types of insurance in terms of the size of the return and risk
resulting from it has been shown that most types of insurance have an average profit,
excluding motor insurance Complementary and mandatory, in addition to the most
common types of insurance profitability is pension insurance, where profit per pound per
0.9991 followed by insurance against theft and transport insurance. Conversely study
showed that the average profit of the fire is 0.6252 per SP one, but the risk in this type of
insurance is very high risk where the standard deviation of about 2.06264, and followed in
terms of high-risk insurance hulls of ships where the standard deviation for securing ships
.81732. With regard to the following types: life insurance and pension insurance and
engineering insurance of civil liability and personal insurance are all enjoying a good profit
and the average rate risk is acceptable. The study recommended that insurance firms
should carry out a study and the reality of insurance in the Syrian market in terms of the
size of the risks and value of insurance premiums, especially life insurance types where
there are no actuarial studies specialist, in addition to giving fire insurance and compulsory
motor vehicle further study and development of many of the controls of would reduce the
size of the dangers that it contains two types of insurance.
