Effect of cyclosporine on hepatic energy status and on fructose metabolism after portacaval shunt in dog as monitored by phosphorus‐31 nuclear magnetic resonance spectroscopy in vivo [PDF]

, 1991
The effect of cyclosporin A on the hepatic energy status and intracellular pH of the liver and its response to a fructose challenge has been investigated using in vivo phosphorus‐31 nuclear magnetic resonance spectroscopy in dogs.

Optimum chemical balance weighing design with diagonal matrix of errors based on balanced block designs

Acta et Commentationes Universitatis Tartuensis de Mathematica, 2004
The paper is studying the estimation problem of individual weights of objects using the chemical balance weighing design under the restriction on the number of times in which each object is weighed. Additionally, we assume that the errors are uncorrelated and they have different variances.

Relations between optimum chemical balance weighing designs for v and v+1 objects [PDF]

Applicationes Mathematicae, 1991
Summary: The incidence matrices of BIB designs for \(v\) treatments have been used to construct optimum chemical balance weighing designs for \(p=v\) or \(p=v+1\) objects. Conditions under which the existence of an optimum chemical balance weighing design for \(v\) objects implies the existence of an optimum chemical balance weighing design for \(v+1\)

Monitoring of the primary drying of a lyophilization process in vials [PDF]

, 2009
An innovative and modular system (LyoMonitor) for monitoring the primary drying of a lyophilization process in vials is illustrated: it integrates some commercial devices (pressure gauges, moisture sensor and mass spectrometer), an innovative balance and

Some Construction Methods of A-Optimum Chemical Balance Weighing Designs

Journal of Applied Mathematics and Physics, 2014
Some new construction methods of the optimum chemical balance weighing designs and pairwise efficiency and variance balanced designs are proposed, which are based on the incidence matrices of the known symmetric balanced incomplete block designs. Also the conditions under which the constructed chemical balance weighing designs become A-optimal are also
