Abstract:
Baker's yeast, Saccharomyces cerevisiae, is a well-studied model system in genetics and molecular biology. It is also a promising system for experimental ecology, evolution, and epidemiology, and is very important in the fermentation industry. The large amount of information generated by studies using this organism cannot be fully exploited until sufficient ecological data is gathered. Only when the natural environment of S. cerevisiae is well characterized can research using this yeast as a model system be put into context. The lack of information about the natural environment of S. cerevisia

Abstract:
Previous research has revealed that the functions of the dorsomedial (DMS) and dorsolateral (DLS) striatum are dissociable. Some of this evidence was obtained using the win-stay (WS) task, in which lights at the entrances to the arms of a radial maze indicate the locations of food. This task is thought to depend on stimulus-response (S-R) learning mediated in part by the DLS. The present experiments used different versions of the WS task developed for an automated 8-arm radial maze. In Experiment 1, no evidence for a Pavlovian-to-instrumental transfer effect on WS learning wa

Abstract:
This thesis seeks to analyse the central features of the new scheme of strict liability for loss caused by product defects which was introduced by Part 1 of the Consumer Protection Act 1987. The features to be examined are: the meaning of 'defect'; the meaning of 'product' and the chain of liability; the role of warnings; recoverable and non-recoverable loss; the development risks defence; other defences and prescription and limitation. The aim of the thesis is to assess the impact of these new rules, against the background of the various proposals for reform which had been mooted and in the l

This study seeks to understand how agencies with strict land use requirements and plan formulate and translate land use objectives into budgets and spending priorities. Characteristics such as legislation, policy and management body structure were examined alongside various influences to determine the extent to which these decision processes are impacted and provide insight into how such influences may be usefully levered and potentially transferred to other situations. In particular, the research was focussed on some of the "drivers" to the budgeting and land use prioritising processes. It is

Full text
Abstract:
Altered dopamine (DA) neurotransmission is implicated in neurological and psychiatric disorders. Positron Emission Tomography (PET) imaging of DA release has mainly been restricted to striatal areas, rich in D2/D 3 receptors, owing to the moderate affinity of the radioligands used. To measure extra-striatal DA release, where D2/D3 receptor concentrations are much smaller, an approach using a high affinity radioligand, such as [18F]Fallypride, is required. The aim of the present study was to investigate in healthy volunteers the suitability of [ 18F]Fallypride to measure variations in D2/D3 rec

Abstract:
Many efficient ways for two-level logic minimization of Boolean functions have been presented. They can obtain the minimum number of product terms and no product terms can be replaced by a product term with fewer variables. But the minimal result obtained from the previous cube-based algorithm is prime and irredundant only for some of the connected outputs and therefore the network that results from the multilevel synthesis might have redundancy and hence untestability.<br>In this thesis, we present a logic minimization algorithm for synthesis of strictly irredundant networks.

Abstract:
Convergent evidence suggests that psychomotor stimulant drugs, such as amphetamine and cocaine, exert their rewarding and locomotor stimulant effects via increased dopamine (DA) transmission in the ventral striatum in rats. Additionally, recent evidence suggests that DA transmission importantly mediates the aversive effects of nicotine. The ventral striatum is not, however, a homogenous structure. Rather, anatomical and behavioural evidence suggests the presence of several discrete subregions. The most prominent of these are the core and medial shell regions of the nucleus accumbens, and the m

Abstract:
Drug addiction is a worldwide problem that imposes significant costs on society. Aggravating the problem is that we continue to have a poor understanding of vulnerability factors and treatment targets. To date the best implicated brain system is the ascending mesolimbic dopamine cell pathway and its regulation by descending cortical input. The present thesis first reviews the literature describing possible roles of dopamine in addiction, and the relationship between pre-frontal cortical function and striatal dopamine.

Abstract:
One of the important processes involved in working memory is the monitoring of information held in memory. Monitoring refers to the tracking of different events that may have occurred at different times or places in order to make a decision or perform an action. It is required at times when executive tasks are involved, such as set-shifting tests. Indeed, in order to perform a set-shift, one often needs to keep track of the remaining available rules. Recently, fMRI studies have demonstrated that the dorsolateral prefrontal cortex (DLPFC) plays an important role in the monitor

The overall approach was based on Weber's theory of abstraction, which requires the identification of the broadest number of variables as possible.

In controlled conditions, coating of sorghum seeds with arabic gum and inoculum powder did not affect seed germination or inoculum viability. However, one week at 40°C significantly decreased the viability of the inoculum by 31%. Fungus growth and chla
