يهدف البحث التالي إلى توصيف عمل معاصر الزيتون في منطقة الدراسة مع محاولة عرض بعض المزايا التنافسية التي تقدمها هذه المعاصر. إن أغلب المعاصر المدروسة هي معاصر حديثة و ذات استثمار فردي عمره وسطياً 12 سنة، مما يعني أن هذا القطاع يدار من قبل مجموعة من الأشخاص لديهم خبرة جيدة قد تساهم في رفع أداء العمل في المعصرة.
The following research aims to characterize the work of olive mills in the study area with an attempt to offer some of the competitive advantages offered by these mills. Most of the studied mills are modern mills and have an individual investment of an average age of 12 years, Which means that this sector is managed by a group of persons with high expertise may contribute to raising the performance of the work in the mill.

Phenolic compounds are known to be present in high concentration
in various of agro industrial wastes such as olive mill wastewater. As
they are highly biorecalcitrant a possible treatment by Advanced
Oxidation Processes has to be investigated.
T
he photocatalytic degradation of the phenolic acids p-Hydroxybenzoic
acid, Dihydroxybenzoic acid, gallic acid, vanillic acid, syringic acid) in the
presence of TiO2 deposit on a glass plate has been reported. A comparison for
the adsorption properties and the kinetics of reaction have been studied. The
kinetics were found to be first order for all compounds and were compared
with the compounds’ structures. The reaction rate for the compounds was
found as the order Di-HBA < GA < p-HBA ≈ SA ≈ VA.
The influence on the photdegradation rate of various parameters as pH, and
substrate’s concentration was studied for p-Hydroxybenzoic acid only. It was
found that the reaction is pH and substrate’s concentration dependence.
A removal efficiency (50-70%) was determined after 5hr using UVlamp
(15W- λ=360nm) and it increased up to 95% when H2O2 was
added.
Thirteen phenotypes of cultivated wild olive were selected during 2007- 2008
from four orchards in Mesiaf region, to study oil percentage and fatty acids
contents in these types for choosing types for oil production, in order to
propagate and cons
erve them in a germplasm, and then to be cultivated
because they have adapted to local climate in this region. The results were
analyzed statistically by using Gen-State program to calculate least significant
differences between values. The results confirmed the high biodiversity in these
studied types, and they were classified into five groups according to their oil
percentage and contents of oleic acid. The oil percentage ranged from 3.9 to
27.3 %, and the fatty acids had significant differences between them, the oleic
acid was in olive oil between 56.7 and 75.5%. The types P1-1 and p1-3 showed
the best results for producing oil.
The adsorption ability of those pollutants by the Anion exchanger
( A36MB ) have been studied. A good results have been obtained
after( 8 hour ) as a real time of this operation . The removal ratio
reach up to( 96.62%) , when the quantity of the s
olid ( Anion
exchanger) was about 10 gr and the wastewater about 150 gr
where the ratio of( sold/water) was about 6.666 % .
This research was carried out during the years (2010 – 2014), in
order to study the vigour for trees of six wild olive types which were
selected from the natural forest (In situ) in Moseif region, and the
vegetative rooted cutting at 4 years old in the nursery (Ex situ) in
comparison with The variety Al Safrawi.
The research aims to study the reality of olive production in the province of Latakia,
and of time-series extends from the year 2002 to the year 2013, and based on the indices,
growth rates, and simple regression, has been studying the reality and
the evolution of
olive production, and areas planted with olive trees, and the number of trees olive during
the period studied, and it was the most important results:
*The relationship between the olive production and the time during the period (2002-
2013) is a strong and positive relationship, where 73% of the developments in the
production of olive explained by changes of time, and the rest is due to the influence of
other factors not included in the model.
*The relationship between the cultivated olives space and time during the period
(2002-2013) is a very positive and strong relationship, where 87.3% of the developments
in the areas cultivated with olives interpret the changes of time, and the rest is due to the
influence of other factors not included in the model.
*The relationship between the olive trees and the time during the period (2002-2013)
is the relationship between positive and very strong, since 89% of the developments in the
olive trees explained by changes in time, and the rest is due to the influence of other factors
not included in the model.
