利用生态脆弱度的灰色评判法建立了沙质荒漠化的干扰－应变关系，进而求算了不同荒漠化程度样地的生态脆弱度，结合气候、地貌、植被、土壤等特征指标对东北西部沙质荒漠化地区土地荒漠化作出评价：该区的土地沙质荒漠化可分为强度沙漠化、中度沙漠化、轻度沙漠化、微度沙漠化、潜在沙漠化五个级别，各等级及其相应的生态脆弱性、植被群落多样性、群落稳定性等指标可用于中小尺度的荒漠化土地评价图的绘制，其可作为土地荒漠化防治的重要理论依据．

景观规划的特点与一般原则

本文从景观生态学的角度对景观规划的目标、任务和基本原则进行了论述，分别介绍了城市景观规划、农村景观规划、园林风景区的景观规划、旅游名胜区的景观规划以及自然保护区的景观规划等五个方面的应用内涵。其共同目标是人与自然关系的协调，时空结合意义上的可持续发展，即建立生态可持续的景观。通过经济规划、环境规划与景观设计的结合，使得区域开发、资源利用与生态保护相衔接与配合，生产建设、生活建设与生态建设相适应，从而达到经济效益、社会效应与生态效益的最终一致。

深部流体对天然气成藏影响

深部流体是地球内部物质和能量交换最活跃的组分，超临界状态存在的深部流体中含有大量的气体，通过地震、火山或以其他各种构造通道向地球的浅部运移。上升过程中由于物理化学条件变化（主要是温度和压力降低），其中的挥发分首先从岩浆中析出，在合适的构造部位直接聚集成藏；同时流体上升过程中带出的大量地球深部的物质或能量为天然气形成提供有利条件。中国东部郯庐大断裂带气藏天然气碳同位素及稀有气体地球化学特征表明，深部流体直接或间接对天然气形成以及运移有重要的影响。国外一些天然气形成的模拟实验结果也显示以二氧化碳和水为主的流体在深部油气的无机合成、运移和富集中起着重要的作用。深入研究深部流体与天然气形成之间的关系可以为天然气勘探提供重要的方向和目标，将对天然气成因及来源产生重要的理论和实践意义。

Small angle scattering characterisation of micellar systems and templated architectures

The work described in this thesis reports the structural changes induced on micelles under a variety of conditions. The micelles of a liquid crystal film and dilute solutions of micelles were subjected to high pressure CO2 and selected hydrocarbon environments. Using small angle neutron scattering (SANS) techniques the spacing between liquid crystal micelles was measured in-situ. The liquid crystals studied were templated from different surfactants with varying structural characteristics. Micelles of a dilute surfactant solution were also subjected to elevated pressures of varying gas atmospheres. Detailed modelling of the in-situ SANS experiments revealed information of the size and shape of the micelles at a number of different pressures. Also reported in this thesis is the characterisation of mesoporous materials in the confined channels of larger porous materials. Periodic mesoporous organosilicas (PMOs) were synthesised within the channels of anodic alumina membranes (AAM) under different conditions, including drying rates and precursor concentrations. In-situ small angle x-ray scattering (SAXS) and transmission electron microscopy (TEM) was used to determine the pore morphology of the PMO within the AAM channels. PMO materials were also used as templates in the deposition of gold nanoparticles and subsequently used in the synthesis of germanium nanostructures. Polymer thin films were also employed as templates for the directed deposition of gold nanoparticles which were again used as seeds for the production of germanium nanostructures. A supercritical CO2 (sc-CO2) technique was successfully used during the production of the germanium nanostructures.

Health of the older worker in Ireland - occupational physical and psychosocial factors in the autumn of work life

Introduction: Worldwide, governments are striving to keep people in work to an older age. However, little is known about the effects of work on an older workforce. This thesis aims to investigate the importance of job characteristics to the antecedents and evolution of cardiovascular disease and functional limitations for the older worker (50+ years). Methods: Three studies were used in this thesis. The 5C (Cork Coronary Care Case- Control) Study investigated the association between job strain and a coronary event in males (n=208) 35-74 years old. The Mitchelstown Study examined the association between job characteristics and positive lifestyle behaviours and further, job characteristics and blood pressure for males and females 50-69 years (n=2,047). Finally, the Cork & Kerry Study investigated the physical effects of manual work and reported functional limitations/disabilities in a sample of 60-80 year olds (n=362). Results: Results from the 5C Study show a clear difference between younger (<50 years) and older (≥50 years) workers, with older workers who had a coronary event more likely to have high job strain and low job control. Data from the Mitchelstown Study showed workers with intermediate possibility for development or high quantitative demands (versus low) at work significantly more likely to have co-occurrence of positive lifestyle behaviours. Further, those who had high possibility for development were more likely to have high systolic blood pressure with no indication of recovery from this activation at night. Physically demanding work as reported by the participants of the Cork & Kerry Study was associated with functional limitations and activities of daily living disability for both the paid and unpaid worker. Discussion: The findings from this piece of work highlight the necessity to examine job characteristics and health outcomes in isolation for the over fifties. The challenge is to get this information into the workplace.
