Electroosmotic flow (EOF) commonly involves inhomogeneous fluids in practical applications. EOF hysteresis, which is defined as direction-dependent behavior, has been extensively investigated for dissimilar solution pair systems. Hitherto, there no investigation being conducted to examine the effect of microchannel diameter on hysteresis phenomenon. In this investigation, current monitoring exp...
Measurements of aerosol particles and clusters smaller than 3 nm in diameter are performed by many groups order to detect recently formed or emitted nanoparticles for studying the formation early growth processes particles. The Airmodus nano-Condensation Nucleus Counter (nCNC), consisting a Particle Size Magnifier (PSM) Condensation (CPC) is versatile tool as small ca. 1 mobility diameter. It o...
to determine the droplet characteristics of agricultural spray nozzles through water sensitive paper (wsp), the non-circular and overlapped spots appearing on the water sensitive paper surfaces are eliminated. in the conventional approach, the procedure is done according to the subjective self determined estimation of the operator. the objective of this study was to develop a practical alternat...
Expanded Polystyrene (EPS) is a lightweight, malleable, adjustable strength material with good cushioning properties. This paper introduces the concept of diameter-thickness ratio and high-thickness to analyze impact force duration data tests different thicknesses EPS plates sand cushion layers under environments, which shows that within range thickness can be withstood by structure shed cavern...
تولید انبوه مرکبات در ایران، لزوم درجه بندی کیفی این محصولات را برای ورود به بازارهای جهانی تقاضا می کند. به همین منظور، در تحقیق حاضر، یک دستگاه سورتر (sorter) روباتیکی طراحی و ساخته شد تا بتواند میوه ها را بر اساس اندازه به سه قسمت کوچک، متوسط و بزرگ تقسیم نماید. دستگاه شامل بخش های نرم افزاری و سخت افزاری می باشد. قسمت سخت افزاری دستگاه از دو واحد تشکیل شده است. واحد اول، واحد تصویر برداری م...
Strabismus surgeons continually seek to achieve the best results from their surgery, which means stable motor alignment and sensory improvement with a minimum number of procedures. But the tables and algorithms that we employ for the number of muscles to be included in the surgery, and for the doses of surgery, are often not appropriate for difficult or unpredictable cases. The ability to modif...
PURPOSE First, to determine whether a silicone light-adjustable intraocular lens (IOL) can be fabricated and adjusted precisely with a light delivery device (LDD). Second, to determine the biocompatibility of an adjustable IOL and whether the lens can be adjusted precisely in vivo. METHODS After fabrication of a light-adjustable silicone formulation, IOLs were made and tested in vitro for cyt...
PURPOSE To compare the success rates and stabilities of postoperative alignment between adjustable and the non-adjustable surgeries in the treatment of sensory exotropia. METHODS A retrospective analysis was performed on all patients with sensory exotropia who had undergone unilateral lateral rectus recession and medial rectus resection (R&R) between January 1998 and August 2005. Thirty-four ...
