the kinetic of fischer-tropsch synthesis over a co-precipitated fe-ce catalyst was investigated in a fixed bed micro reactor. experimental conditions were varied as follow: reaction pressure 1-15bar, h¬¬¬2/co feed ratio of 1-3 and space velocity of 3600-5400 h-1 at the temperature range of 270-310°c. 4 models according to the langmuir-hinshelwood-hougen-watson (lhhw) type rate equation were der...

The purpose of this study is to examine the neurological differences in protein levels and concentrations in Autism. The following are two aspects that will be introduced to the field: (1) the utilization of the Fischer 344 rat as an animal model of Autism and (2) the evaluation of the protein tyrosine hyroxylase (TH). TH is the enzyme that catalyzes the conformation of L-tyrosine into LDOPA, t...

In this paper, we discuss some properties of joint spectral {radius(jsr)} and  generalized spectral radius(gsr)  for a finite set of upper triangular matrices with entries in a Banach algebra and represent relation between geometric and joint/generalized spectral radius. Some of these are in scalar matrices, but  some are different. For example for a bounded set of scalar matrices,$Sigma$, $r_*...
