Through the last centuries Scientists and Researchers have created analytic and
geographic multi-methods and formulas for the definition of elastic curve’s unknowns of
beams. We have seen that most of these methods had matched in their end formulas
, while
they only differed by the analytic basis for the differentiating of these formulas, that their
introductions depended on different physic expressions and mathematic relations. This
scientific work contains a concise preview for the definition relations and methods of
elastic Curve’s unknowns of beams available, so that the expression about these in an easy
and collective expression with agreement of the depended analytic method by the
Researcher. That can avail of the academic job on the first hand, and it helps the structural
analyzer choose the proper and easier device for his structural analysis for the definition of
elastic Curve’s unknowns of studied structural system.
Sahl Al-Ghab zone is characterized by the availability of natural and human
appropriate conditions for the cultivation of cotton, and it's one of the most desired
agricultural crops for export, in addition to the big need for local textile mills wi
th both of
its public and private sectors, and it's also one of the strategic and social crops. However,
between 2005-2013, cotton cultivation fell back in this region to be replaced mainly by
wheat in addition to other crops, and the main reasons for this decline is that there is no
proportionality between the price of cotton and production costs, as the price of the
kilogram of cotton rose from 31 S.P in 2005 to 100 S.P in 2013, while the price of the liter
of diesel – the main factor in the cultivation of cotton – rose from 25 S.P in 2005 to 60 S.P
in 2013.
Through this research, We knew the reasons for the decrement of cotton cultivation
in Sahl Al-Ghab zone and choosing the wheat and nothing else to replace it, especially that
wheat cultivation didn't achieve better economic returns of cotton.
On the contrary, it had negative results in terms of non-application of the agricultural
cycle and the spread of diseases such as wheat rust disease that spreaded in Sahl Al-Ghab
zone in the last years and which reflected negatively on production.
The natural resources that are available in a region are considered to be the starting
point and the basis for the development of the tourism industry and this for the region
advancement this economically and service and socially, and to show the p
otentials of any
area touristically we must perform a touring assessment of its natural resources, from here
came the importance of this research which dealt with performing a touring assessment of
natural resources in Alhaffeh area that is characterized by uniqueness of its resources and
excellence at the province level, the assessment was performed using GIS program to reach
the desired results.
The study was conducted in the eastern region of Syria to know the extent of
cultivation development of wheat and cotton production and the factors
affecting these crops during 1996-2010. The results showed that the effect of
time on the productio
n and productivity of wheat was not changed statistically,
while the cotton area was decreased significantly during the study period. The
total production of wheat was also affected significantly and positively by
cultivated area and planting costs per hectare, and negatively by purchase
price, while the production of cotton was affected significantly and positively by
costs and purchase prices. According to the geographical region, the results
showed that the production in the eastern region was significantly affected by
Al-Raqqa production for wheat and cotton crops and Al-Hassake production
for wheat crop. However, wheat productivity at Deir Ezzor was significantly
superior compared to Al-Raqqa and Al-Hassake. The study recommended
expanding the cultivation of wheat and cotton and support and expand the role
of agricultural extension.
