We have developed a quantitative reverse transcription polymerase chain reaction (RT-PCR) method, using both internal and external standardisation, to quantitate fg amounts of pre-pro-thyrotropin releasing hormone (pre-pro-TRH) mRNA in the paraventricular nucleus (PVN) of individual laboratory rats. A constant amount of internal standard is coamplified with both the cDNA of each unknown specime...

purpose: this paper has two main goals: first, to evaluate the position of geological survey of iran library through the assessment of internal (strengths and weaknesses) and external (opportunities and threats) environment; and then, provide solutions and strategies to help library managers and administrators to achieve their goals, missions and visions. methodology: among the existing models,...

During the last decade stabilization and other control design problems for linear systems subject to constraints, especially those with actuator saturation, have received much attention. Whenever the magnitude of the control input is bounded, internal stabilization in either global or semiglobal sense is possible if and only if the open-loop system is asymptotically null controllable with bound...

This paper puts forth an open model of transition to democracy challenging the conventional wisdom of the literature on processes of democratisation, which focuses almost exclusively on domestic factors. International variables are thus at the centre of explanations for regime change. The article argues that transitions do not occur in a vacuum and presents a theoretical model that can be usefu...
