Studies of a Rat Liver Ribonuclease Inhibitor Protein Gene

The cytoplasmic ribonuclease inhibitor-ribonuclease system has been detected in a wide variety of tissues and species and is thought to play an essential role in the regulation of RNA metabolism and hence protein synthesis. This hypothesis is based on the observation that tissues with high levels of RNA and protein synthesis are associated with correspondingly high levels of free inhibitor and vice versa. However, the precise nature of this regulatory function is unknown. Therefore, the aim of this project was to isolate cDNA clones of ribonuclease inhibitor from a rat liver library in the expression vector, lgt11 using polyclonal antiserum, to characterise the resultant clones and to use the clones to determine the extent to which ribonuclease inhibitor activities are controlled at the level of gene expression

On the relationship between performance and intangible cultural heritage

This chapter deliberately ranges across disciplines because we wish to move towards a better understanding of the notion of performance in relation to ICH, where both terms are inherently transdisciplinary. We fi rst examine the concept of performance as it is understood in Theatre and Performance Studies, focussing on those aspects which are pertinent to ICH – embodiment, liminality and effi cacy. Second, we turn to Heritage Studies and outline how ideas of and about performance shape our understanding of heritage and its sociocultural dimensions. Thirdly, and fi nally, we investigate aspects of the tension between the performance of and the research on ICH through the lens of ethnomusicology, a discipline that is shaped by the tensions between the wealth of tacit cultural knowledge acquired by learning to perform works of ICH and the need to communicate such knowledge in research outputs

Fitting Correlated Hadron Mass Spectrum Data

We discuss fitting hadronic Green functions versus time $t$ to extract mass values in quenched lattice QCD. These data are themselves strongly correlated in $t$. With only a limited number of data samples, the method of minimising correlated $\chi^2$ is unreliable. We explore several methods of modelling the correlations among the data set by a few parameters which then give a stable and sensible fit even if the data sample is small. In particular these models give a reliable estimate of the goodness of fit.Comment: 14 pages, Latex text, followed by 3 postscript figures in self-unpacking file.

Efficient Hadronic Operators in Lattice Gauge Theory

We study operators to create hadronic states made of light quarks in quenched lattice gauge theory. We construct non-local gauge-invariant operators which provide information about the spatial extent of the ground state and excited states. The efficiency of the operators is shown by looking at the wave function of the first excited state, which has a node as a function of the spatial extent of the operator. This allows one to obtain an uncontaminated ground state for hadrons.Comment: 18 pages, Latex text, followed by 11 postscript figures in self-unpacking file.
