Potentiometric analysis of fluoride content (as F- ion) in solutions by using fluoride ion-selective electrode is simple, reliable and cheap.Very small concentrations of fluoride-ions (to 10-6 mol/dm3) can be determined by fluoride selective electrode, with regulation of ion strength of a solution and control of concentration of hydroxide ions and
Abstract Copy number variation (CNV) is an important part of human genetic variations, which is associated with various kinds of diseases.To tackle the limitations Noodles of traditional CNV detection methods, such as restricted detection types, high error rates, and challenges in precisely identifying the location of variant breakpoints, a new met
NANOG is a divergent homeobox protein and a core component of the transcriptional circuitry that sustains pluripotency and self-renewal.Although NANOG has been extensively studied on the transcriptional Phone Case level, little is known regarding its posttranslational regulation, likely due to its low abundance and challenging physical properties.H
This paper presents PS1 a novel double-direction inchworm in-pipe robot, called the Cam-Linkage Robot (CLR), used to carry sensors and instruments to perform inspection and cleaning jobs inside pipelines.The prototype has been developed to improve the driving ability and reduce the difficulty of control.CLR is suitable for pipe diameters from 360�
The 3-D needled C/C preforms with different densities deposited by chemical vapor infiltration (CVI) method were used to Phone Case fabricate C/C-SiC composites by gaseous silicon infiltration (GSI).The porosity and CVI C thickness of the preforms were studied, and the effects of preform density on the mechanical and thermal properties of C/C-SiC c
