TPA is known to cooperate with an activated Ras oncogene in the transformation of rodent fibroblasts, but the biochemical mechanisms responsible for this effect have not been established. In the present study we used c-fos promoter-luciferase constructs as reporters, in transient transfection assays, in NIH3T3 cells to assess the mechanism of this cooperation. We found a marked synergistic interac
The purpose of this paper is to show how it is possible to derive the advantages of the subject choice view of passivization (Holmer 1996a, 1996b) without necessarily resorting to the somewhat unconventional (and, in traditional terms, illicit) concept of Case Cancellation. Instead, I adopt two proposals made by Bittner & Hale 1996 with respect to Case-marking and the structure of Case-marked
It is well-known that there exists a critical control weighting parameter which results in an unstable controller design if the uncontrolled system is unstable or nonminimum phase and a single stage cost functional is used. The purpose of this note is to show that the determination of this parameter reduces to solving a root-locus problem.
RFID technology can improve inventory and pipeline visibility. However, there is scarce research on how to tactically and operationally make use of RFID-captured data. The purpose of this paper is thus to explore the advantages and characteristics, from a material control perspective, of keeping track of goods in real time in a supply chain. A framework regarding the potential gains of tracking u
Abstract in Spanish Este trabajo presenta algunas reflexiones preliminares acerca del desarrollo rural en el nordeste de Argentina a la luz de los cambios socio-económicos y políticos acontecidos en los últimos veinte años aproximadamente. Así, por ejemplo, los procesos de descentralización que han tenido lugar en este país durante la década de 1990 ilustran la complejidad de las estrategias de de
Double-stranded DNA bacteriophages are highly stressed under the high internal pressure that is described as stored energy. Most of them eject their genome into the host bacteria via receptor binding. In the previous work, isothermal titration calorimtery (ITC) was used, for first time, to directly measure the heat released during DNA ejection from the phage lambda, triggered in solution by solubi
A statistical analysis of amplitudes corresponding to multipath components in outdoor (urban/suburban) channels is presented. The study is based on short-term complex impulse response measurements conducted in Stockholm at 1.88 GHz carrier frequency with 5 MHz bandwidth. The actual investigations show that the Rice distribution gives the best fitting in the Kramer-von-Mises sense. Further it is sh
