يهدف هذا البحث إلى تطبيق طريقة الشكل المتجانس لفك الثني (Deconvolution Homomorphic) المستخدمة في معالجة المعطيات السيسمولوجية و المعطيات السيزمية لمعالجة المعطيات الجيوراداريـة. من أجل تحقيق هذا الهدف تم إجراء تعديلات على خوارزمية تحديد الإشارة بحيـث تناسـب خـصائص المعطيات الجيورادارية، ثم وضع برنامج حاسوبي يتضمن عدة مراحـل بـدءاً بتحويـل صـيغ تـسجيل المعطيات الحقلية و قراءتها، و انتهاء بتنفيذ عملية التصفية العكسية. بين البحث أهمية طريقة التصفية العكسية في رفع قدرة التمييز على المقطع الجيوراداري، و ذلك من خلال زيادة المحتوى الترددي للمعطيات الجيورادارية الحقلية بشكل واضح. و قد اختُبرت هـذه الطريقـة على معطيات جيورادارية حقلية و قيست بأجهزة مختلفة و بمواقع مختلفة، و أظهرت النتائج فعاليـة هـذه الطريقة في مفاضلة المقطع الجيوراداري مما ساعد في إغناء عملية التفسير و توسيع دائـرة الاسـتعمال التطبيقي للمعطيات الجيورادارية.
This research aimed to use the homomorphic deconvolution, applied for processing seismologic and seismic Data, for processing the georadar Data. To reach this aim, some changes in the algorithm of signal determination have been carried out, in order to match the properties of georadar data, I wrote a computer Program, that include several steps, starting from transforming and reading the field data, and ending by performing the inverse filtering. The research shows the importance of the homomorphic deconvolution to improve the resolution of Georadar-Record by raising the frequency content on the field – georadar data. Using various field data measured at various Locations by different Instruments, to test this method of deconvolution. The results shows the efficiency of this method in differentiation the image of georadar-Record, and consequently help the interpretation, which maximize the applicability of the georadar data.

The aim of this research consists of the study the possibility of using the
geophysical methods to estimate the shallow geological structures and to show
the detailed lithological changes.
The geoelectric and georadar methods have been implemented
in an area at
Torgau city in Germany.
These methods have been applied on polluted aquiferes. Also geotechnical
study has been implemented in this area to compare the geophysical results.
The results show high resolution in both methods to estimate the
underground geological structures. By the integrated both methods, the
horizontal and vertical changes of these structures have been estimated with
high accuracy.
Latakia is a Syrian city that generates approximately 800 tons per day of municipal solid
waste MSW, and the final disposal of MSW is in Al-Bassa open dump with no biogas
capturing or leachate collection systems. Thus, a life cycle assessment appro
ach LCA was
used to determine the optimal strategy of municipal solid waste management. to find the
most eco-friendly scenario, first, the composition study of MSW was conducted in Latakia.
The results of first step are to be utilized as a reliable data source in establishing a
complete picture of the environmental performances of municipal solid waste management
systems with a life cycle perspective. The functional unit of the study was selected as one
ton of MSW generated in Latakia. System boundaries included treatment and disposal of
MSW using different scenarios: the open dump of waste, sanitary landfilling with gas
recovery, and a material recovery facility MRF combined with a sanitary landfill and gas
recovery. Data on the process was gathered from a field study conducted in Latakia, and
from SimaPro 8.3.0 literature and libraries. The data was evaluated with IMPACT 2002+
methodology and the assessed environmental impact categories were climate change,
human health, ecosystem quality, and resources. According to the results, while open
dumping has been confirmed as the worst waste final disposal method, landfilling with gas
recovery and material recovery facility showed better performance and is considered as a
solution towards improved sustainability to overcome the existing waste management
problem.

Fever is a common problem in intensive care unit (ICU) patients, A large proportion
of patients admitted to the ICU are likely to develop fever of unknown origin at some point
of their stay there. Objective: This study aimed to compare between the
effects of the
application of iced gastric lavage with the application of ice packs to reduce the
temperature among critically ill patients. Material and methods: the study was conducted
of (40) critically ill patients at ICU department at Al Assad University Hospital and Al
Wattani Hospital in Latakia city whose were intubated and there temperature degree
ranged from 39 °C to 40 °C lasting for more than 30 minutes ago. The sample was
randomly divided into two experimental groups. Two tools were used to collect data.
Results: This study showed that iced gastric lavage is more effective than using iced
packs to reduce the temperature among critically ill patients.
Recommendations: this study recommended to Apply iced gastric lavage alone or
with other methods to reduce the temperature degree among critically ill patients.
