MIDDLE TO LATE JURASSIC BIOFACIES OF SAUDI ARABIA

Saudi Arabian Jurassic carbonate hydrocarbon reservoirs were first examined stratigraphically using microfauna. Current microfaunal studies concentrate on the identification and constraint of palaeoenvironmental variations and determination of high-resolution depositional cyclicity of the reservoir carbonates. It is apparent that the environmental sensitivity of benthonic foraminifera provides a potentially valuable technique for the determining subtle variations in the depositional environment and also providing a proxy for sea-level fluctuations

The Military\u27s Role in Counterterrorism: Examples and Implications for Liberal Democracies

The author examines historical and contemporary examples of military involvement in counterterrorism, outlining the specific roles which the armed forces of liberal democracies have performed in combating terrorism, both in a domestic and international context. He describes the political, strategic, conceptual, diplomatic, and ethical problems that can arise when a state’s armed forces become engaged in counterterrorism, and argues that military power can only be employed as part of a coordinated counterterrorist strategy aimed at the containment and frustration, rather than the physical elimination, of the terrorist group(s) concerned.https://press.armywarcollege.edu/monographs/1335/thumbnail.jp

Weak and strong comets in the solar wind

When within the inner solar system, comets possess gaseous atmospheres. The gases therein are ionized, and eventually join the solar wind. This thesis describes an investigation of the interaction of comets with the solar wind. The work begins with an overview of the processes involved in the comet-solar wind interaction region, and the domains and boundaries that exist in the region. A review of remote observations of cometary ions is given. The characteristics of visible plasma features are summarized, together with the theories proposed to explain them. An overview of the Giotto spacecraft and its instruments, and a description of its mission to two comets are presented. Ground-based observations were obtained of the ion features present in Comet C/1996 B2 Hyakutake. The morphologies and motions of the comet's plasma features are described. The formation of tail rays was captured during a high temporal resolution image sequence. A gas production rate estimate is derived from the observations, and a model of ray morphologies is proposed, based partly upon observational evidence. 45P/Honda-Mrkos-Pajdusakova and C/1996 Q1 Tabur were also observed; however, no strong ion features were detected. An analysis of the plasma features of 26P/Grigg-Skjellerup then follows. A description of the solar wind conditions at that comet during the Giotto encounter is given, and an estimate of its production rate is made. Ground-based observations of Grigg-Skjellerup are compared to in-situ Giotto data. Morphological features were detected in ground-based images; it is proposed that they could have been linked to certain solar wind discontinuities. A qualitative description of a model of ion ray formation then follows. The thesis concludes with a summary of the main results

Why I chose to become a teacher and why I might choose not to become one: a survey of student teachers’ perceptions of teaching as a career

A detailed questionnaire about why they chose teaching as a career and the challenges that they face on their ITT course was completed by 189 third year student teachers on a third year BA in Primary Education with QTS programme at a university in Wales. The findings showed that several factors contributed to their choosing a career as primary school teachers, including reasons related to perceived teaching ability, altruistic reasons, intrinsic reasons, and extrinsic reasons. The data also revealed that the main stressors faced by the respondents were linked to four factors, namely: high levels of accountability; the pressure of monitoring; the continual demand for change; and the perceived lack of respect given to the profession. Differences were found between the male and the female respondents in the ways they perceived their role within the profession. The findings have important implications for all those who are concerned with the attracting and retaining the most competent teachers to/in our primary schools

Direct processing of structural thermoplastic composites using rapid isothermal stamp forming

A novel rapid isothermal stamp forming process is proposed which enables the rapid manufacture of structural thermoplastic composite laminate parts directly from multilayer hybrid fabrics comprising stitched unidirectional carbon fibre-thermoplastic polymer veil. The process employs rapid-response variothermal tooling, allowing macro-scale (fabric forming/draping) and micro-scale (fibre wetting/laminate consolidation) composite material transformation processes to occur isothermally above the constituent polymer matrix melt temperature (Tm), thus manufacturing a composite component directly from a hybrid dry fabric in a single press cycle in a relatively short overall cycle time. The proposed rapid isothermal stamp forming (RISF) concept is presented, and details of the process are given along with some considerations made throughout the formulation of the process. As a result of the RISF process development work, candidate manufacturing parameters were derived, delivering parts that exhibit acceptable composite laminate microstructure and mechanical performance within a press station cycle time of 330 s

Childhood poverty in Wales and its implications for schools: a survey of trainee teachers’ perceptions

With a third of all pupils in Wales in poverty it is essential that trainee teachers in the principality understand the nature of poverty and develop a practical understanding of how best to deal with its negative effects. In order to explore trainee teachers’ perceptions of these issues a detailed questionnaire was completed by 94 of the 96 third year trainee teachers on a BA in Primary Education with QTS programme at a university in Wales. The data revealed a mature understanding of the main issues. Childhood poverty was seen by the respondents as a state of material, educational and emotional deprivation which prevents children and young people from developing their potential as individuals and from developing into fully active members of society. The respondents felt that schools had a central role to play in tackling the negative effects of poverty and that there were a range of positive measures that all schools needed to take in order to achieve this. The data also revealed that there were some practical areas related to combating childhood poverty which the respondents were yet to gain full confidence in tackling. The survey has significant implications for all those concerned with childhood poverty and initial teacher education in Wales and beyond
