A quantum pipette
Curved quantum waveguides are known to bind particles. We show that a number of charged fermions in such a trap can be tuned by an external electrostatic eld; if the latter is slowly increased, the bent duct can serve as a single particle ejector.
متن کاملA mechanical pipette.
An automatic pipette is a very useful equipment for any laboratory carrying out Kahn tests on a large number of sera. A number of devices were tried in a field laboratory which was functioning as a serological laboratory for the CeylonArmy Command during the years 1945 and 1946. A mechanical pipette which can easily be prepared with materials salvaged from a small workshop is described below. T...
متن کاملINTRACYTOPLASMIC SPERM INJECTION (lCSI) IN MICE BY A NEW HOLDING PIPETTE
Mice are ideal models for ICSI experiments because of the ease of culturing eggs/embryos in vitro and the availability of ample genetic information. Unfortunately, it has been extremely difficult. In this study we improved the mouse ICSI method by using a new holding pipette that was made of two pipettes such that one pipette was pulled and heat merged into the other one. The outer pipette ...

چکیده-پخش بار بهینه به عنوان یکی از ابزار زیر بنایی برای تحلیل سیستم های قدرت پیچیده ،برای مدت طولانی مورد بررسی قرار گرفته است.پخش بار بهینه توابع هدف یک سیستم قدرت از جمله تابع هزینه سوخت ،آلودگی ،تلفات را بهینه می کند،و هم زمان قیود سیستم قدرت را نیز برآورده می کند.در کلی ترین حالتopf یک مساله بهینه سازی غیر خطی ،غیر محدب،مقیاس بزرگ،و ایستا می باشد که می تواند شامل متغیرهای کنترلی پیوسته و گ...
A multifunctional pipette.
Microfluidics has emerged as a powerful laboratory toolbox for biologists, allowing manipulation and analysis of processes at a cellular and sub-cellular level, through utilization of microfabricated features at size-scales relevant to that of a single cell. In the majority of microfluidic devices, sample processing and analysis occur within closed microchannels, imposing restrictions on sample...
