حصاة الحالب واعراضها تؤثر على حياة المريض بصوره سلبيه، عدة علاجات متوفرة لعلاج حصاة الحالب من ضمنها مراقبه المريض، استخدام ادويه تفتيت الحصاة، استخدام موجات الفوق الصوتية تفتيت الحصاة بناظور الحالب، استخراج الحصاة جراحيا او بالناظور البطني, استخدام ناظور الحالب وتفتيت الحصاة بالليزر هي الطريقة المفضلة لعلاج حصاة اسفل الحالب. الهدف من الدراسة:لمقارنه تأثير ومضاعفات استخدام تقنيه الطحن او تقنيه التكسير لحصاة أسفل الحالب باستخدام الليزر وذلك بمقارنه وقت العملية، معدل التخلص من الحصى، معدل احتياج وضع قسطره الحالب والمضاعفات داخل العملية. المرضى والأساليب: ادرج في هذه الدراسة 120 مريض تم تقسيمهم الى مجموعتين : (الأولى) تكسير حصاة الحالب باستخدام تقنيه الطحن وتم تقسيمها الى مجموعتين الأولى حصاة بين 10-15 ملم والثانية حصاة اصغر من 10 ملم, و(الثانية) باستخدام تقنيه التكسير وتم تقسيمها الى مجموعتين الأولى حصاة بين 10-15 ملم والثانية حصاة اصغر من 10 ملم في مستشفى الشهيد غازي الحريري للجراحات التخصصية للفترة من كانون الأول 2019 الى تموز 2022 , تمت المقارنة بين كلتا الطريقتين من حيث وقت العمليه,معدل التخلص من الحصاة، معدل وضع قسطره الحالب, مضاعفات حدثت خلال العملية. النتائج: وقت العملية في النوع الأول (تقنيه الطحن) أكثر من النوع الثاني (تقنيه التكسير) مع وجود فرق كبير ذو دلاله إحصائية، معدل التخلص من حصاة الحالب في النوع الأول أكثر من النوع الثاني بدون وجود فرق كبير ذو دلاله إحصائية، احتياج وضع قسطره الحالب أكثر في النوع الثاني مقارنه بالنوع الأول مع وجود فرق كبير ذو دلاله إحصائية. من حيث المضاعفات خلال العملية، أكثر بالنوع الثاني مقارنه بالنوع الأول بدون وجود فرق كبير ذو دلاله إحصائية. الاستنتاج:ان تفتيت حصاة الحالب باستخدام تقنيه الطحن ذو مضاعفات اقل داخل العملية وذو احتياج اقل لوضع قسطره الحالب، ولكن وقت العملية أطول،تفتيت حصاة الحالب باستخدام تقنية التكسير وقت عمليه أقصر وأكثر مضاعفات داخل العملية وأكثر احتياج لوضع قسطره الحالب.
In this paper fractional Maxwell fluid equation has been solved. The solution is in the Mettag-Leffler form. For the corresponding solutions for ordinary Maxwell fluid are obtained as limiting case of general solutions. Finally, the effects of different parameters on the velocity and shear stress profile are analyzed through plotting the velocity and shear stress profile.
Abstract:
Today, the financial and banking sector is witnessing a qualitative shift thanks to financial technology services, which provide their services to many individuals and companies in quick, easy and less expensive ways compared to traditional means. Financial technology is a new form of financial science that combines financial transactions and technological skills concerned with providing financial services and improving the work environment within Banking institutions, and financial technology provides many advantages such as lower transaction costs, instant payment, and saving more time and effort in conducting banking

Show MoreHuman behavior is one of the topics that has captured the attention of researchers throughout the ages, and motivation is one of the manifestations of this behavior, which indicates the extent of interest in a particular topic and their unwillingness to rush towards a particular topic. The topic of motivation is one of the important topics of interest to the teacher and coach in the field of sports. The aim of this research was identifying the level of motivation for junior students, and the differences in the dimensions of motivation for junior students in squash lessons. We used the descriptive survey method, and the research sample was chosen randomly. Only male of the junior students in the College of Phys

This transportation of objects is done via a vehicle equipped with a robot arm and an FPGA. The path between the two locations is followed by recognizing a black line between them. The black line is sensed by Infrared sensors (IR) located on the front and on the back of the vehicle. The Robot was successfully implemented by programming the Field Programmable Gate Array with the designed system that was described as a state diagram and the robot operated properly.
Henrik Ibsen is considered one of the greatest writers on society and its problems in the modern era, as his works deal with society in all its forms in a realistic way, in which he presents the motives and consequences of social problems and their impact on society to study these problems through them to and propose solutions through theatre. Most of his writings were very serious about addressing these social issues. The method of collecting information in the study came through reviewing a group of sources related to realistic theater and social theory, then reading the plays covered in a critical and analytical reading. Based on that, the method of writing this study came and used a group of sources that directly relate to the s

Photodynamic Action (PDA) by using appropriate wavelength of irradiation conjugated with porphyrin derivatives is a powerful mechanism of tumor destruction. Hematoporphyrin derivative has been shown to selectively localize in neoplastic cells and then cause destruction of them by generation of singlet oxygen when activated by low power He-Ne laser. Light which used in this study has been emitting from this laser has a wavelength equal to 632.8 nm (red light). Doses of laser had been varied from 3.6 J/cm2 to 14.4 J/cm2 . The beam of laser adjusted with a modified tissue culture plate. Cell lines had exposed to Hematoporphyrin D (HpD) for 24 hours before Laser exposure, their concentrations were varied from 5 µg/ml to 80 µg/ml. Resu

fluorescence technique using 650 nm CW diode laser in comparison with the histopathological
investigation. Five permanent molar teeth were extracted from adult individuals for different reasons
(tooth impaction, periodontal diseases, and pulp infections); their ages were ranging from 20-25 years
old. Different carious teeth with varying clinical stages of caries progression were examined. An
experimental laser fluorescence set-up was built to perform the work regarding in vitro detection and
quantification of occlusal dental caries and the determination of its actual clinical carious lesion depth by
650 nm CW diode laser (excitat
The aim of this research is to design and construct a semiconductor laser range finder
operating in the near infrared range for ranging and designation. The main part of the range finder is the
transmitter which is a semiconductor laser type GaAs of 0.904 mm wavelength with a beam expander,
and the receiver with its collecting optics. The characteristics of transmitter pulse width were 200ns and
threshold current 10 Amp. and maximum operating current 38 Amp. The repetition rate was set at 660 Hz
and maximum output power about 1 watt. The divergence of the beam was 0.268o. A special computer
code was used for optimum optical design and laser spot size analysis and for calculation of atmosphere
attenuation.
