Breakup of Latex Doublets by Impaction

Wake Capture, Particle Breakup and Other Artifacts Associated with Counterflow Virtual Impaction

Counterflow virtual impaction is used to inertially separate cloud elements from un-activated aerosol. Previous airborne, ground-based and laboratory studies using this technique exhibit artifacts that are not fully explained by impaction theory. We have performed laboratory studies that show small particles can be carried across the inertial barrier of the counterflow by collision and/or coale...

control of the optical properties of nanoparticles by laser fields

در این پایان نامه، درهمتنیدگی بین یک سیستم نقطه کوانتومی دوگانه(مولکول نقطه کوانتومی) و میدان مورد مطالعه قرار گرفته است. از آنتروپی ون نیومن به عنوان ابزاری برای بررسی درهمتنیدگی بین اتم و میدان استفاده شده و تاثیر پارامترهای مختلف، نظیر تونل زنی(که توسط تغییر ولتاژ ایجاد می شود)، شدت میدان و نسبت دو گسیل خودبخودی بر رفتار درجه درهمتنیدگی سیستم بررسی شده اشت.با تغییر هر یک از این پارامترها، در...

Doublets in Translation

Dystocia caused by chronic fecal impaction.

case Report The patient, a 19-year-old gravida 2 para 1, was admitted to our hospital on 31 October 1990. By history of last menstrual period she was 42 weeks' gestational age. She complained of the onset of labor pain 3 hours before admission to the hospital. The patient's prenatal care consisted of two prenatal visits to an outlying health department. Her medical history revealed chronic cons...

Describing RNA structure by libraries of clustered nucleotide doublets.

The rapidly increasing wealth of structural information on RNA and knowledge of its varying roles in biology have facilitated the study of RNA structure using computational methods. Here, we present a new method to describe RNA structure based on nucleotide doublets, where a doublet is any two nucleotides in a structure. We restrict our search to doublets that are close together in space, but n...
