conclusions specimen adequacy and diagnosis of inflammatory reaction were better in liquid base smear and convention smear, respectively. results specimen adequacy and smear quality were significantly better in liquid base sampling (p = 0.03); presence of benign cellular changes was not different between the two groups (p = 0.389). diagnosis of bacterial vaginosis was significantly better with ...
در این کار پژوهشی ابتدا با استفاده از یک روش سنتزی اصلاح شده 4-نیترو فنیل فروسن را از طریق آریلاسیون فروسن با نمک دی آزونیم تحت شرایط انتقال فاز تهیه کردیم .سپس 4-نیترو فنیل فروسن را با pd/c با استفاده از nabh4 با جریان ملایمی از گاز نیتروژن درحلال متانول به 4-فروسنیل آنیلین احیا کردیم .(لازم به ذکر است که آمین سنتزی به عنوان حد واسط مهمی برای سنتز شیف بازهای فروسنی liquid crystal محسوب میشود)....
earlier studies have shown conclusively that a tuned liquid damper (tld) is effective for controlling vibrations in structures subjected to narrow-banded wind excitations. a recent numerical study has shown that if the design parameters of a tld are properly set, this device could also be very effective for controlling structural vibration to broad-banded earthquake excitations. here the result...
Cylindrical liquid storage tanks are considered as vital structures in industrial complex whose nonlinear dynamic behavior is of crucial importance. Some of these structures around the world have demonstrated poor seismic behavior over the last decades. There are several methods and techniques for rehabilitation and reducing damages in these structures which among them passive control devices, ...
tuned liquid dampers (tld) are among passive control devices that have been used to suppress the vibration of structures in recent years. these structures must be adequately presentable as an equivalent single degree of freedom system with long fundamental period. the tld, located at the top floors of the structure, can dissipate the external input energy into the system through the sloshing ef...
mobile carrier properties of two schiff base ligands, named bis(2-hydroxypropiophenone)-1,2-propanediimine (n2o2) and bis(1'-hydroxy-2'-acetonaphthone)-2,2'-diiminodiethylamine (n3o2), dissolved in dichloromethane for the extraction of copper(ii) ions from an ammonium buffer feed phase into a nitric acid solution (receiving phase) were investigated and compared. the parameters influencing the t...
Background: Cervical cancer presents as major cause of morbidity and mortality especially in developing countries like India. Various screening programs are implemented for its early detection and treatment, which makes it imperative to have a reliable screening investigation for wider application. Objective : TO evaluate the role of Liquid base cytology and Colposcopy and compare their efficac...
Introduction: Human exposure with Lead can cause health problems. Use of cosmetics, especially lipsticks contaminated by this heavy metal is counted one of the entrance ways of lead into body. The purpose of this study was to evaluate the amount of lead in lipstick in cosmetics shops of Kerman, Iran. Methods: This descriptive study was performed during Jan to Feb - 2010. All cosmetics sh...
