Solar and wind energy is considered as one of the best renewable energy resources
because it Available and economical . We can take advantage of these two resources of
renewable energy in Katina area in Homs for designing and building a bilateral r
esources
(solar-wind) electric power system, depending on the daily bending of the wind speed and
the solar radiation intensity in the studied area.
This research studies the design of a hybrid wind and solar system by selecting its
components that available in the local market in terms of their nominal, technical
specifications, based on the technical and economic studies and the corresponding
international standards. The obtained results showed that we have approximately (1246.7
Kw/Year) surplus during the year for the benefit of consumers, which makes the system
economically feasible for investment, as explained in research needs an additional resource
to feed the load and charge the energy-savings with (3360.2 w/day) that constituting (50.4
%) of the volume of the load in addition to the practical results provides a theoretical
database, whether for the researcher or the investor in the field of renewable energies,
particularly in terms of the efficiency of selecting the system’s components.
This research investigates the main factors (domestic and foreign) affecting inflation rate in Syria.
Choosing the factors is based on the analysis of the major economic hypothesis concerning inflation determinants such as: excess purchasing power,
cost push inflation, foreign inflation.
By using OLS method, we find long run function, and it shows that the excess purchasing power has no significant effect on inflation rate.
The error correction model shows that high cost rate has the biggest effect on inflation rate in the short run.
This research aims to study the problem of liquidity excess، so it considers from the important problem that is facing the Islamic banks especially in this obstacles:
1- Modernity time of Islamic banks.
2- littleness of financial tools that used to
manage the liquidity in Islamic banks.
3- Nonexistence Law are fitting with targets and field of activity of Islamic banks.
And It is done that through knowing the liquidity in these banks and the tools used to manage the liquidity، inside to the best Islamic financial tools that Islamic banks are able to use in manage the liquidity.
