Regional oxidative metabolism was studied in vivo. Oxygen availability was monitored from polarographic electrodes in frontal cortical and subcortical tissue. The rate of oxygen extraction in these regions was estimated at frequencies of up to 3 measurements per minute. Transient ischemia of the frontal regions was induced and the resultant decay in the oxygen trace was analyzed kinetically. Th...

Microarrays and RNA Sequencing have become the most important tools in understanding genetic expression in biological processes. With measurments of thousands of genes’ expression levels across several conditions, identification of differentially expressed genes will necessarily involve data mining or large scale multiple testing procedures. To the date, advances in this regard have either been...

Recent subcritical VENUS-F experiments showed that fission chambers with a threshold deposit like U-238 can essentially improve the on-line sub-criticality measurments beam interruption method, which is currently supposed to be main method for ADS MYRRHA. To suppress uncertainty caused by fissions in U-235 impurities, fraction of U should accurately known. Three PHOTONIS CFUL01 type were purcha...

in this paper, the present state of knowledge about axial mixing in gasliquid reactors is reviewed. a brief outline of the methods for measuring residence time distribution(rtd)of various phases in a multiphase reactor is presented. this is followed by a short description of differential and stage-wise models for characterizing back mixing from rtd measurments. backmixing characteristics of som...

This work focuses on the use of parallel hardware to improve the simulation speed of equation-based object-oriented Modelica models. With this intention, a method has been developed that allows for the translation of a restricted class of Modelica models to parallel simulation code, targeted for the Nvidia Tesla architecture and based on the Quantized State Systems (QSS) simulation algorithm. T...

SgmlQL is a SQL like language to manipulate SGML or XML documents distributed over a network. In this article we present the query optimizer that we developped for this language. We distinguish between local queries, which access documents stored in the site from which the query is issued, and distributed queries, which access documents stored in sites differents from the one from which the que...

It is shown that the dependence of the cerebral blood flow (CBF) on mean arterial blood pressure (MABP) can be described with a simple model having the following assumptions. Below certain MABP (denoted as MABP1) there are no autoregulatory or feedback mechanisms influencing CBF. Between MABP1 and MABP2 (MABP at which breakthrough accurs) there is a linear (on MABP) dependent feedback with a sl...
