هدف هذا البحث إلى دراسة إمكانية استخدام الطرائق الجيوفيزيائية في تحديد التراكيب الجيولوجية تحت السطحية في المجالات القليلة العمق و إظهار التغيرات الليتولوجية التفصيلية. تم فـي هـذا البحـث تطبيق الطريقة الجيوكهربائية باستخدام تقانة التخطيط الجيوكهربائي و الطريقة الجيورادارية في إحـدى المناطق في مدينة تورغاو في ألمانيا. نُفذ هذا الاختبار على نموذج طبقات مائية معرضة للتلـوث، و قـد استعين بسبور جيوهندسية أجريت في موقع الدراسة لمعايرة النتائج الجيوفيزيائية و مقارنتها. أظهرت النتائج قدرة التمييز لكلتا الطريقتين في تحديد التراكيب الجيولوجية تحت الـسطحية، حيـث أمكن تحديد التغيرات الأفقية و الشاقولية لهذه التراكيب بدقة عالية بالاستخدام المتكامل لنتائج الطريقتين.
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.

تعد البكتريا الممرضة المنقولة عن طريق الغذاء سبباً للامراض والوفيات وقد قاومت العديد من الجهود المبذولة للكشف عنها وتشخيصها .
The aim of this study was diagnosis and conservative treatment of
Pyometra in dogs with antiprogestins (such as Aglepriston) and
prolactin inhibiting (Cabergoline) associated with synthetic PGF2α
(Cloprostinol) will replace ovariohysterectomy.
Tw
enty-three dogs (8,5 ± 3,2 years old and 5-35 kg weight) from
different breeds with know breeding history and open or closed type of Pyometra, were used in this study. All dogs underwent a general and gynecological examination including Ultrasonography.
Research aims to detect the big caves (cavern)in basalt
regions and determinate its predictable and unpredictable path
,and choosing the ideal application seismic land survey. And
the possibility for immediate determination of the cavern in
field
,by realizing the incoming cavern indications , at seismic
field.
The purpose of research is the study and analysis of some of the stochastic semi-gradient methods and their applicability to find the optimal solution for the issues of optimization are subject to the effects Random and conditions are controlled by c
hance, as we proved the convergence of some of these mathematical methods and their effectiveness for some of the issues of stochastic non-convex and equipped objective function and specific constraints and where taken energy complex solar as an example
The results of a seismic profiling application are strongly dependent upon
field parameters, So every area has its own character and difficulty .To
increase the energy of seismic sources and to choose the most suitable source
arrays are important
factors to avoid the difficulty of the area and to help
attenuate ground role. To get good engineering seismic resolution, the
displacement of sources must be perpendicular to the profile line within a
definite distance .
