جرى في هذه البحث إعداد وبناء تجربة ضوئية لدراسة تشتت رايلي التوافقي الشديد الناتج عن جزيئات عضوية محلولة بمحل مناسب. تتضمن دراسة تشتت رايلي التوافقي الشديد من حيث المبدأ دراسة إسهامات معاملات ثنائي القطب وثمانية الأقطاب للمركبات العضوية. و قد درست الطواعية اللاخطية لستة مركبات كيميائية عضوية مختلفة من زمرة اليردينوم و الكوانيلينيوم و معقدات البور العضوية. تساعد دراسة الطواعية اللاخطية على اكتشاف الجزيئات الأكثر كفاءة و تحديدها لتوليد التوافق الثاني لضوء الليزر الذي يمكن استخدامه لاحقاً في تصنيع المعقدات الكيميائية (البوليمرات).
In this paper, an optical setup to produce harmonic hyper-Rayleigh light scattering (HRS) from organic molecules in solution has been built up. In principle, HRS measures contribution coefficients of dipole and octupole parts. The nonlinear susceptibility of the second order of six organic molecules in solution from different chemical components such as Pyridinium, Quinolinium groups and organic Borone complexes has been determined. The nonlinear susceptibility measurements help to discover and select the most efficient molecules which can be used later as polymer matrices.

This study was conducted during the 2011-2012 and 2012-2013 seasons in
Abu-Jarash orchards area in Damascus to identify the effect of improved
organic materials as sludge, manure and compost in improving some soil
physical characteristics and whea
t productivity. Results showed that the three
types of organic material affected the physical characteristics of the studied
soil. They decreased its bulk density, increased its total porosity and increased
its ability of holding water at field capacity. Results also showed that the
compost of city wastes was the best in improving soil physical properties. The
three organic materials, particularly the sludge increased the total productivity
of wheat (Sham3).
This study aimed to investigate curing efficiency of a second generation - light
emitting diode(LED) curing unit to polymerise two kinds of resin ,one depends upon camphorquinone as a
single photo initiator while the other uses co-initiator besides camphorquinone .
This paper aims at investigating the effect of organic matter
content on the engineering properties of the soil.
The effect of the organic matter on both the consistency limits and strength have been investigated. The results show that the organic
matter increases both the plasticity and the strength of soil.
Mathematical formula is presented in which the unconfined
compression strength of the soil is related to the organic matter
content. It was concluded that increasing the organic matter
content increases the displacement corresponding to the maximum shear stress. In addition, the effect of the organic matter has been studied and the results show that the organic matter increases the compressibility of the soil.
Stabilizing the soil with cement has been investigated as well. The
results show that adding the cement to the soil improves the
strength of the soil and decreases its swelling potential.
Depending on the organic matter content, a mathematical formula
is presented to determine the required cement ratio to treat the
soil to decrease its swelling potential.
This research sheds light over an important activity of the religious beliefs in
Kingdom of Mary, which is The faith, concerning the vital role of diviners and their
participation the King authority in running the citizens affairs especially, that
the religious
beliefs of this Kingdom was characterized by intellectual riches which was obviously
appeared in its discovered texts, and which was based on trying to find out a convincing
interpretation for the human mentality at that time, concerning the mysterious phenomena,
in which the nature has played the main role in answering such these questionable matters.
So, the research focused on the role of the diviner as a mediator between the divine
symbols and the human beings through several divining practices such as, prediction,
dreams analysing and setting the judgments.
The German Byzantine relations between 1137-1146 were
alliance relationships against Roger II King of Sicily, because in the
increasing of the influence of Roger II in Italy the influence of
German and Byzantine empires was diminished, also the Byzantine
Emperor John Komenan saw in the ambitions of Roger II a direct
threat to the interests of Byzantium in the East and the West.
