Abstract:
Human life history (LH) strategies are theoretically regulated by developmental exposure to environmental cues that ancestrally predicted LH-relevant world states (e.g., risk of morbidity–mortality). Recent modeling work has raised the question of whether the association of childhood family factors with adult LH variation arises via (i) direct sampling of external environmental cues during development and/or (ii) calibration of LH strategies to internal somatic condition (i.e., health), which itself reflects exposure to variably favorable environments. The present research tested between these possibilities through three online surveys involving a total of over 26,000 participants. Participants completed questionnaires assessing components of self-reported environmental harshness (i.e., socioeconomic status, family neglect, and neighborhood crime), health status, and various LH-related psychological and behavioral phenotypes (e.g., mating strategies, paranoia, and anxiety), modeled as a unidimensional latent variable. Structural equation models suggested that exposure to harsh ecologies had direct effects on latent LH strategy as well as indirect effects on latent LH strategy mediated via health status. These findings suggest that human LH strategies may be calibrated to both external and internal cues and that such calibrational effects manifest in a wide range of psychological and behavioral phenotypes.

Abstract:
This thesis examines variation in the life-history parameters of primates using comparative techniques. Several theories of life-history evolution are introduced in the first chapter, together with a summary of the previous work on this topic. Scaling methods are used to separate variation in life-history parameters that is correlated with body weight from that which cannot be predicted from an animal's size. These methods are described in detail in Chapter 2. Chapter 3 describes the variation found in body size and basal metabolic rate and correlations with phylogeny, diet, habitat and other aspects of ecology. Patterns of variation in reproductive parameters, particularly reproductive rates (as measured by the intrinsic rate of natural increase, r_{max}) and reproductive effort (as measured by prenatal and postnatal infant growth rates), are described and compared with patterns reported in other studies. Possible reasons for the scaling relationships found are suggested and the influences of metabolic rate, phylogeny, diet, habitat and other aspects of ecology are investigated. This is carried out for all primates in Chapters 4-6 and in Chapter 7 there is a closer look at the cercopithecine monkeys. It is suggested that r_{max} is influenced by the predictability of the environment, with more unpredictable environments being associated with a higher r_{max} that more predictable environments. However, this is only found when body weight effects are removed from the r_{max} data. Growth rates do not appear to be correlated with environmental predictability but are mainly correlated with body size and relative metabolic rate. There is some indication that the degree of parental care may also be correlated with relative growth rates. It is concluded that no single theory of life-history evolution can amount for the variation found in primate life-histories, but that some aspects of several theories may be useful in describing the patterns found.

This study used data from literature and data from the field to analyse the patterns of variation in life history characters among members of the liverwort family Lophoziaceae. A combination of Principal Component and Cluster analyses was used to analyse data from literature in testing for recurrent suites of life history variation among species of the family. Data from literature were also used to examine the relationship between mode of reproduction and reproductive system (sexuality) and between diaspore (spore or gemma) frequency and sexuality. Data from the field were used to establish diaspore (spore and gemma) sizes and their production per capsule or shoot and to test for relationships between diaspore size and production per shoot/capsule and also between diaspore sizes and proportion of germination.

Abstract:
This thesis addresses the life-history strategies of cursorial riparian spiders using field- and laboratory-based research. Species distributions were compared to important habitat variables with particular reference to disturbance. The nature of a "habitat templet" for riparian spiders was also examined. No 'typical' riparian spider fauna was identified. Most dominant species were opportunistic aeronauts, associated with disturbed habitats. Disturbance accounted for little variation in distributions. This is attributed to all sites being disturbed, with the actual frequency of flooding having little influence. Light penetration, the proportion of sand in the substrate, amount of exposed substrate and leaf-litter depth all significantly influenced the distribution of spiders. The influence of disturbance on the life-history traits of two congeneric and co-habiting lycosids (Paradosa argicola and P. amentata) was examined using manipulated levels of flooding. This showed that both species have evolved different strategies to cope with the consequences of flooding. P. amentata, a widespread generalist, had more plastic development periods and instar sizes across different treatments. Traits of P. agricola, a habitat specialist, were not plastic and this species has evolved a greater tolerance to flooding. Examination of the reproductive strategies of P. agricola and P. amentata revealed that both species can adjust their reproductive output. Both species produced smaller clutches later in the season. Offspring of these clutches had larger instars and shorter development periods, which is assumed to increase juvenile survival in conditions of greater environmental stress. No trade-off existed between the numbers and sizes of eggs within clutches. Maternal body size, however, was positively associated with clutch size and weight. Maternal size had no influence on egg sizes.

Abstract:
The Teredinidae are a major economic pest of wooden coastal structures, causing billions of Dollars worth of damage per annum. To fully understand the threat posed by teredinids it is necessary to examine their biology at a number of different levels. These include: the anatomical adaptations which facilitate their wood-boring and wood- feeding life-style; the mechanism of cellulose digestion, which is aided by cellulolytic symbionts retained in bacteriocytes on the teredinid gill; the early life history strategies, particularly larval development; improving the means of teredinid identification for this taxonomically challenging group; and monitoring the spread of teredinids and the impacts global warming may have on their distribution. This thesis set out to address a number of these questions. The teredinid Lyrodus pedicellatus is able to complete a life-cycle feeding exclusively on wood and is one of the most destructive of the marine borers. In this study, X-ray micro-computed tomography (MicroCT) was used to produce a three-dimensional computer-rendered model of L. pedicellatus, to examine the anatomical adaptations for wood-digestion. This was complemented by a transcriptomic analysis of the major digestive organs, which set out to determine whether L. pedicellatus is capable of independently producing cellulolytic enzymes. Investigation of the early life history strategy aimed to provide new insights into the larval-parent interactions during brooding and development – the most crucial phase in the life-cycle of teredinids. Finally, integrative taxonomy was used to improve the taxonomic resolution of the Teredinidae and these methods helped to confirm the identity of an invasive Caribbean species of teredinid, Teredothyra dominicensis, which has recently invaded and established breeding populations in the Mediterranean Sea. This research provides the first detailed evidence that brooded L. pedicellatus larvae derive extra-embryonic nutrition from their parent. This extended parental care allows larvae to settle and metamorphose immediately after release. Development to sexual maturity is then rapid and individuals become gravid with brooded larvae within six weeks. The examination of the digestive system of L. pedicellatus using MicroCT revealed a number of adaptations towards xylotrophy. The elongated stomach, specialised digestive gland, large caecum with a well developed typhlosole and long intestine are all modifications enabling a more complete utilization of wood for nutrition. These results corresponded with the transcriptomic analysis which suggests the specialised digestive gland produces a range of cellulolytic enzymes. A phylogenetic survey of the Teredinidae using integrative taxonomy provides a robust model for future identification of species, including cryptic species, within this taxonomically challenging group. This formed the basis for the identification of T. dominicensis, a species thought to be confined to the Caribbean and Gulf of Mexico, which has recently invaded the Mediterranean. This species was found to have established a substantial breeding population in the region, which produce large quantities of larvae which could settle and metamorphose. Thus, T. dominicensis may be considered an established species in the Mediterranean. Providing a more accurate means of identification and increasing knowledge on the larval development and early life histories will help efforts to monitor the spread of teredinids and identify areas under threat from the destruction they cause. Furthermore, understanding the anatomical and molecular mechanisms which allow teredinids to deconstruct lignocellulose into monomeric sugars may provide new means of protection for wooden structures and provide novel enzymes for use in the biofuel industry.

Full text
Abstract:
Six of the southwest and western nuclear plants have formed an alliance to jointly apply and share in new technologies to increase plant reliability. Life cycle management (LCM) is an EPRI developed process to evaluate and select the best long-term maintenance strategies for important plant systems, structures and component groups. Both, technical and economic assessments are made to arrive at a strategy that provides the highest reliability at the least cost. Among those SSCs chosen for LCM are the Station Transformers, the Main Generator, Turbine Controls, Underground Piping and the Circulating Water System (CWS). The application of the LCM process to the STARS plants is demonstrated for the CWS. The process steps from information gathering, establishing component maintenance and performance history, failure rates and current maintenance practices to aging and technical obsolescence assessment are reviewed. Information sources for generic failure rates, best industry practices, PM and PdM technologies, aging/degradation and performance trending are discussed. Lastly, methods for the modeling and analysis of the economic parameters are presented. The results of the CWS LCM plans for four of the STARS plants are compared and conclusions are summarized.

Full text
Abstract:
The management of pressure equipment operating in a cyclic service can be difficult as little guidance is provided in the codes of construction or in any of the post construction guidance documents. In terms of design, the ASME Section VIII, Division 2 Code does provide guidance for the design and fabrication of vessels that will be in a fatigue service. Of specific interest are those vessels that were designed to ASME Section VIII, Division 1 with varying levels of attention paid to the cyclic nature of the operation. This becomes a problem when operating facilities must determine the long term strategy for a piece of equipment where fatigue is the only (or dominant) method of degradation. With the variation in design methods, methods of addressing fatigue crack growth, material properties, and the desire to minimize inspection expenditures for this type of equipment; practical guidance for long term inspection considerations is presented in this paper. A case history for a Pressure Swing Adsorbtion (PSA) vessel that is subject to cyclic pressure only is discussed to illustrate design considerations, inspection strategies, and determination of remaining life. This provides a fairly simple and approachable example for determination of remaining life and inspection strategies, as well as highlighting regions of interest in these types of vessels. The same approach can then be applied to equipment where more complex (mechanical, thermal) cycling occurs.

Abstract:
Abstract A prosthesis is a replacement limb that must be functionally sound, comfortably fit, durable, and aesthetically pleasing. Difficulty in prescription is further amplified by each patient’s unique needs and the variability within patient data. The clinician’ s education and prior training is critical in effectively navigating the wealth of patient specific information needed to prescribe a prosthesis and rehabilitation plan that increases the likelihood of long-term patient success. Education and training significantly vary, however, from country to country, and in Lower Income Countries (LIC) a lack of formalized prosthetic training contributes to a lower quality of life for resident amputees. Prosthetists and technicians in LICs face further challenges due to a lack of material resources and formal medical infrastructure. This study was motivated to understand the types of patient information that influence decision-making strategies during prosthetic prescription and compare strategies across expert and novice groups. The results of this study suggest that salient factors are different between each clinician group and is influenced by the complexity of the patients’ case. Activity level of the amputee influenced novices’ prescription, whereas amputee’s motivation, insurance, and health history influenced experts’ prosthetic prescription. Future work exploring the utility of complimentary or supplemental prescription tools, particularly for prosthetists in LICs, is discussed.

In 16th International Conference on Nuclear Engineering. ASMEDC, 2008. http://dx.doi.org/10.1115/icone16-48467.

Full text
Abstract:
Many commercial nuclear power facilities have been in operation well over 20 years, and many facilities have been or will have their original 40 year operating license renewed for an additional 20 years. The anticipated stresses to plant equipment and the longer service life increase the challenge to maintain reliable equipment performance. Establishing equipment maintenance programs that are effective and compliant with applicable regulations is critical to avoid unplanned equipment unavailability and the potential costs of lost generation. An equipment reliability (ER) strategy for commercial nuclear power plant equipment is described that considers the programmatic recommendations of the Institute of Nuclear Power Operations ([1], [2]), Electric Power Research Institute ([3], [4], [5], [6]), Nuclear Energy Institute standard nuclear business model [7], Nuclear Regulatory Commission ([8], [9], [10], [11]), and industry societies and working groups, such as the American Society of Mechanical Engineers ([12], [13]). All ER strategies must properly implement mandatory requirements and commitments ([14], [15], [16]). Additionally, ER strategies should also consider the appropriate manufacturer/vendor recommendations, industry and plant personnel operating experience feedback, equipment operating and maintenance history information, etc. As a result, the ER strategy includes reviewing multiple information sources to inform the decisions to either include or exclude the specific maintenance activities that impact reliability. Ultimately the maintenance program is tailored for each equipment application and implements the necessary maintenance activities while avoiding the cost of performing unnecessary maintenance activities.

Full text
Abstract:
Abstract This study presents a novel metaheuristic algorithm that uses a physics-based model for multi-fractured horizontal wells (MFHW) to accurately predict the estimated ultimate recovery (EUR) for unconventional reservoirs. The metaheuristic algorithm creates a sizeable number of stochastic simulations and keeps the simulation results from those random models that closely reproduce observed production data. Unlike other optimization methods, the proposed algorithm does not aim at finding the exact solution to the problem but a group of sufficiently accurate solutions that help to construct the partial solution to the optimization problem as a function of production history. Results from this work provide sufficient evidence as to why traditional decline curve analysis (DCA) is not a suitable solution for production forecasting in unconventional reservoirs. Two case studies are discussed in this work where results from both modeling strategies are compared. Evolutionary prediction of EUR over time using DCA behaves erratically, regardless of the amount of historical production data available to the regression model. Such erratic behavior can, in turn, yield an erroneous estimation of key economic performance indicators of an asset. In contrast, the proposed metaheuristic algorithm delivers precise and accurate results consistently, achieving a significant reduction of uncertainties as more production data becomes available. In conclusion, the proposed partial optimization approach enables the accurate calculation of important metrics for unconventional reservoirs, including production forecasting and expected productive life of an asset.

Common problems with respect to the implementation of a change include: • changes that are not technically sound, • lack of careful consideration of the ramifications, • poor execution, and • failure to effectively communicate change information to key personnel. A Management of Change (MoC) system is a combination of policies and procedures used to evaluate the potential impacts of a proposed change so that it does not result in unacceptable risks. A thorough MoC system manages both temporary and permanent modifications in a ship or offshore unit including equipment, materials, operating procedures and conditions, and personnel. An effective MoC system will not only minimize significant impacts on safety and the environment, but will incorporate strategies in managing the associated business risks on quality, continued commerce and security. A system requiring MoC for every modification is likely to become onerous and unproductive. This paper provides guidance for selection of the activities and systems to be subject to management of change, the life-cycle applicability, types of changes to be evaluated, and boundaries and overlaps with other administrative programs or elements. It describes key functions and interrelationships for personnel at various levels of a representative organization. In summary, this paper describes the core principles to be considered when developing and implementing an MoC program that will optimize existing safety and risk management efforts.

Abstract:
Abstract In 2005, NGC, Petrotrin and Repsol E&P T&T Ltd. as joint venture partners, acquired the TSP asset with Repsol as the operator. The three fields, Teak, Samaan and Poui, have been in production for over 40 years and are highly complex, extremely compartmentalized and consist of over 10 different sands and reservoirs. Over 100 PVT files for the three fields are available; most of which were done in the 1970's by different labs using different protocols and procedures. All files were handed over in paper form which needed digitization as well as validation. Valid PVT data provides vital information for the characterization of reservoir fluids. The establishment of fluids' physical and PVT properties help determine in situ and stock tank volumes, strategies for production, flow assurance issues for facilities design and provides guidelines for effective and efficient reservoir management throughout the life of the asset. Numerous techniques exist for assessing and evaluating the quality of PVT data. This paper will describe the best practices used to validate TSP PVT data, such as the material balance tests and the Y-function linearity tests as well as the applications of the validated data through examples and case studies. Some of which include the development of trends which can be extrapolated for use in new prospects, infill and developmental drilling. Additional benefits include the recognition of flow assurance issues such as wax and sulphur compounds and the sampling and design of relevant PVT experiments for new wells. Production history combined with valid PVT data provides a powerful tool to help in the prediction of expected fluid types and fluid behaviour as pressure changes in planned new wells. It also provides additional technical support for which improvements to the fluid sampling program can be made to acquire the most representative fluid samples from the reservoir.

Abstract:
Pressurized water reactor plant steam generator upper internals have been monitored in accordance with accepted industry practice and on schedules based on the history of good inspection results with isolated cases of failures in a small percentage of plants worldwide. The current practice is, in general, to perform a small sample qualitative visual inspection. The causal factors for the historical events are indicators but, in general, not directly applicable to the current rationale for increased quantitative surveillance. There is an emerging trend toward increased indications of degradation with identifiable causal factors similar to but distinct from the traditional failure mechanisms. Primary and secondary moisture separation components and feedwater ring degradation is increasing as calculated by traditional models and according to qualitative and quantitative inspection results. Two established objective criteria for the performance functions for the steam drum components under consideration are: moisture carryover < 0.25% and material loss of 62.5 mils from nominal component thickness of 0.25 inches. These traditional acceptance criteria can be re-established based on an engineering evaluation of failure modes and effects. Two changes that have increased the concern for unacceptable degradation of steam drum components in recent years are 1) the chemistry improvements to reduce flow assisted corrosion (FAC) in the feed train piping with the concomitant reduction in entrained iron transport into steam generators, and 2) the increase in water-steam flow velocities that result from power uprates. The reduction of entrained particulate into the steam generators is positive with respect to fewer corrodents introduced but may have an unintended and previously under-analyzed effect of the transport of entrained particulate into the upper regions of the tube bundle and into the moisture separation components. The first indications of degraded moisture separator components have begun to emerge and warrant consideration of an increased surveillance program for selected plants. This paper discusses how recent changes in the operating parameters and secondary water chemistry control have created conditions for concern for exceeding the traditional moisture carryover criteria and erosion-corrosion of upper steam drum components, especially in light of extended life operation. Examples of recent developments in inspection results and considerations for improved materials, increased and improved surveillance techniques, and replacement strategies will be presented.

The land acquisition and real estate development have caused rapid disappearance and decline of a large number of traditional villages, resulting in "urban villages" in China. They seem chaotic, but contain rich and colorful social life. The living environment is really harsh, but people always maintain close relationship with each other. They are different from neither the modern urban nor traditional villages, but they have their own unique vitality. Such heterogeneous space is always a symbol of historical change and cultural collision which, according to the French philosopher Michel Foucault, can be called Heterotopias. In order to study this heterotopic phenomenon, the triangular area of Guandongdian district in Beijing has been chosen as the object of this case study. With the in-depth investigation of interviews, observation, statistics and sketches, this paper is trying to interpret the characteristics of the heterotopic state of the urban village from three aspects of social form, urban morphology and architectural feature. Eventually, in order to keep the complexity and diversification of urban village, several strategies are put forward for reference to future transforming practice. References Foucault, M.

Abstract:
The main recommendations of the panel report can be summarised under four headings: 1. From Source to Sea: River systems, from their source to the sea and beyond, should form the focus for research projects, allowing the integration of all archaeological work carried out along their course. Future research should take a holistic view of the marine and maritime historic environment, from inland lakes that feed freshwater river routes, to tidal estuaries and out to the open sea. This view of the landscape/seascape encompasses a very broad range of archaeology and enables connections to be made without the restrictions of geographical or political boundaries. Research strategies, programmes From Source to Sea: ScARF Marine and Maritime Panel Report iii and projects can adopt this approach at multiple levels; from national to site-specific, with the aim of remaining holistic and cross-cutting. 2. Submerged Landscapes: The rising research profile of submerged landscapes has recently been embodied into a European Cooperation in Science and Technology (COST) Action; Submerged Prehistoric Archaeology and Landscapes of the Continental Shelf (SPLASHCOS), with exciting proposals for future research. Future work needs to be integrated with wider initiatives such as this on an international scale. Recent projects have begun to demonstrate the research potential for submerged landscapes in and beyond Scotland, as well as the need to collaborate with industrial partners, in order that commercially-created datasets can be accessed and used. More data is required in order to fully model the changing coastline around Scotland and develop predictive models of site survival. Such work is crucial to understanding life in early prehistoric Scotland, and how the earliest communities responded to a changing environment. 3. Marine & Maritime Historic Landscapes: Scotland’s coastal and intertidal zones and maritime hinterland encompass in-shore islands, trans-continental shipping lanes, ports and harbours, and transport infrastructure to intertidal fish-traps, and define understanding and conceptualisation of the liminal zone between the land and the sea. Due to the pervasive nature of the Marine and Maritime historic landscape, a holistic approach should be taken that incorporates evidence from a variety of sources including commercial and research archaeology, local and national societies, off-shore and onshore commercial development; and including studies derived from, but not limited to history, ethnology, cultural studies, folklore and architecture and involving a wide range of recording techniques ranging from photography, laser imaging, and sonar survey through to more orthodox drawn survey and excavation. 4. Collaboration: As is implicit in all the above, multi-disciplinary, collaborative, and cross-sector approaches are essential in order to ensure the capacity to meet the research challenges of the marine and maritime historic environment. There is a need for collaboration across the heritage sector and beyond, into specific areas of industry, science and the arts. Methods of communication amongst the constituent research individuals, institutions and networks should be developed, and dissemination of research results promoted. The formation of research communities, especially virtual centres of excellence, should be encouraged in order to build capacity.
