Diphenylcarbazone as an Internal Indicator in Volumetric Analysis. III. Volumetric Determination of Thorium by Ammonium Molybdate

Volumetric determination of columbium.

The quantitative determination of columbium based on reduction by amalgamated zin c and reox idation with potassium permanganate has, in general, produced results that lack both accuracy and precision. A study of t he various factors involved indicates that essential conditions requ ire adequate duration of reduction in t he presence of an excess of zinc and a proper concentration of both acid ...

An Advanced Technique for Volumetric Analysis

An accurate segmentation is critical, especially when the tumor morphological changes remain subtle, irregular and difficult to assess by clinical examination. This quantitative measurement depends on the accuracy of the segmentation method used. The undesired partial volume effect, which lies on a boundary between a high intensity region and low intensity region, makes unerring boundary determ...

Analysis of Volumetric Images: Introduction

Research in 2-D image analysis has more than 30 years of history and has matured reasonably [1]. Research in volume image analysis, however, is still in its infancy. 3-D scanners that produce volumetric images have been around for some time. Although methods to analyze and visualize such images in volume form have been pursued for nearly 25 years now [2], brisk activity in this area is a rather...
