Identification and Characterization of Genes Associated with <i>V-Jun</i> Induced Cell Transformation
<p>The <em>v-jun</em> oncogene was initially identified as the causative agent for fibrosarcomas in chickens. Studies show that overexpression of v-Jun proteins transforms chicken embryo fibroblasts (CEF) <em>in vitro</em>, and forms tumors in chickens<em> in vivo</em>. The mechanisms for this are …

Reflexe a sebereflexe v učební činnosti žáka
Reflexe i sebereflexe nás provází celý život a setkáváme se s ní nejenom ve školním prostředí, ale i v pracovní a osobní sféře. To, že hodnotíme, si často ani neuvědomujeme. Reflexí i sebereflexí vyjadřujeme hodnoty, které jsme si zvolili. I učitelé by této stránce měli věnovat pozornost a snažit …

Combinatorial designs and their automorphism groups
This thesis concerns the automorphism groups of Steiner triple systems and of cycle systems. Although most Steiner triple systems have trivial automorphism groups [2], it is widely known that for every abstract group, there exists a Steiner triple system whose automorphism is isomorphic to that …

Steady-State Poisson-Nernst-Planck Systems: Asymptotic expansions and applications to ion channels
Important properties of ion channels can be described by a steady state Poisson-Nernst-Plank system for electrodiffusion. The solution to the PNP system gives a relation between the current and electric potential of the ions in the channel, called the I-V curve. In this thesis, we will discuss the …
