Manipulation of DNA fibers is very useful technique for gene analysis such as Fluorescent In Situ Hybridization (FISH). In conventional methods for manipulation of DNA fibers, FISH efficiency often decreases due to the tight adhesion between DNA fibers and substrates. In this paper, we propose a micro glass-phonorecord with concentric grooves for suspending DNA fibers with centrifugal force. As...

A comprehensive study of the AC and DC electrokinetic properties of submicrometre latex particles as a function of particle size and suspending medium conductivity and viscosity is presented. Electrophoretic mobility and dielectrophoretic cross-over results were measured for particle diameters ranging from 44 to 2000 nm. The zeta potentials of the particles were calculated from the electrophore...

Abstract A new two-level hierarchical approach to control the trolley position and payload swinging of an overhead crane is proposed. At first level, a simple mathematical pendulum model investigated considering time delay due use vision system. In second chain developed, extending previous vibration suspending chain. The relative displacement measured with sensor, rest state-space variables ar...

The following bacteria were employed as test organisms: Lactobacillus fermenti strain 69L-3, Escherichia coli strain 69L-15, and Serratia marcescens strain ATCC 274. They were cultivated as outlined previously (Major et al., 1955). Broth cultures of the organisms were centrifuged, the spent broth pipetted off, the cells resuspended in a minimal amount of fresh broth, and then the suspension dil...

Individuals with lower limb amputation need a secure suspension system for their prosthetic devices. A new coupling system was developed that is capable of suspending the prosthesis. The system's safety is ensured through an acoustic alarm system. This article explains how the system works and provides an in vivo evaluation of the device with regard to pistoning during walking. The system was d...
