Abstract:

Vibration-based damage detection methods are used in structural applications to identify the global dynamic response of the system. The purpose of the work presented is to exhibit a vibration-based damage detection algorithm that calculates a damage indicator, based on limited frequency bands of the transmissibility function that have high coherence, as a metric for changes in the dynamic integrity of the structure. The methodology was tested using numerical simulation, laboratory experimentation, a

Abstract:

[Truncated abstract] Urinary desmosines have been proposed as a biomarker for inflammatory lung damage. Desmosine, a breakdown product of elastin, is an effective marker of the degradation of elastin and has been studied in many disease scenarios where there is acute and chronic lung inflammation. Lung matrix degradation has been proven in vitro and in vivo with many experiments showing that the excess proteases degrades lung matrix. The secretion of proteases by neutrophils is an innate response of the body to the invasion by micro organisms and when secreted in excess, the protective anti-pr

Abstract:

This thesis has examined the response of testate amoebae communities to restoration at three peatland sites in the UK. It builds upon the use of testate amoebae analysis as a palaeoenvironmental tool by exploring the hypothesis that testate amoebae respond to hydrological conditions in restored mires. Previous research has found that testate amoebae act as good proxies for hydrological condition of intact mires and past conditions but little has been done on their reaction to conditions at damaged sites in the UK. The research aimed to further the understanding of testate amoebae ecology inclu

Abstract:

Agriculture is the dominant source of nitrous oxide emissions, a potent greenhouse gas associated with the use of nitrogen fertilisers. This research examined the relationship between soil active carbon and nitrous oxide to form the basis of a simple field test for farmers to use to estimate the potential for significant nitrous oxide emissions from their soil. Fifteen agricultural soils contrasted by land use history and management were incubated in the laboratory and carbon dioxide and nitrous oxide fluxes were calculated over 100 days. Active carbon was measured as the fraction oxidisable b

Full text

Abstract:

Tillage operations in farming often require high traction forces applied by tractor wheels. These interact with topsoil via a stress system along the contact surface, this interaction resulting in soil and tyre deformation. Topsoil is subject to normal and tangential stresses at the contact surface. The tangential stress rises sharply with increasing traction force and may cause topsoil among tyre lugs to fail, with the consequent formation of a strengthless layer strongly exposed to erosion and an underlying layer where shear deformations contribute to the alteration of soil structure functio

Abstract:

Two sites, situated approximately 60 kilometers apart in southern Quebec, were studied to determine what nutrients were most limiting and to compare growth variation on microsite (3-9m) and landscape scales (100-1000m). One site was found to be 20% more productive than the other growing at 6.9 m3 ha-1 in its fifth year of growth. Principal component analysis found no nutrients to be limiting at the more productive site while the other site appeared to be N and K limited. Microsite scale variation was found to be at least as important as landscape scale variation in explaining

Traditional fecal indicator bacteria such as fecal coliform, E.coli and enterococci have been shown to be unreliable indicators of the hygienic quality of recreational waters under tropical conditions. One of the major reasons for considering these bacteria as ineffective indicators of water quality in warm, tropical regions is that they are consistently found in natural environments (plants, soil, water) in the absence of any significant contamination of these environments.

Training simulators are valuable tools in education of forest machine operators. One important part of the education is to learn about damages occurring due to the forest machines and how they can be avoided. Two types of damages are especially severe, soil compaction and formation of wheel ruts. Compaction reduces the amount of water and nutrients in the soil, and impedes root growth. Furthermore, water is gathered in wheel ruts, leading to transport of organic materia and heavy metals into water courses. These damages can be avoided through planning of the harvesting activities with respect

Abstract:

Nematode communities in black pepper (Piper nigrum L.) agricultural soil in Thanh An, Binh Phuoc province, were investigated. Soil samples were collected in February 2012 at 9 selected sites belonging to 3 pepper groves. The structure of nematode communities and critical ecological indices were determined to estimate environmental status. 26 genera were found. Of those, plant parasitic nematodes such as Meloidogyne, Helicotylenchus, Hoplolaimus, Psilenchus, and Tylenchidae always appear with high frequency and density, whereas the carnivorous nematodes were rarely detected. The nematode densit

Abstract:

Escherichia coli is a bacterial species that lives in the gut of all warm-blooded animals, fish, birds as well as reptiles and is commonly used as an indicator of fecal contamination in water. This project assessed currently used culture based media for the detection of E. coli in irrigation waters used in Arizona and California, and will present recommendations towards the most reliable media for the evaluation of irrigation waters used for produce. Currently, no microbial indicator standards exist for irrigation waters used for produce production in the United States. The produce industry su

Abstract:

The expansion of cities often involves tunnel construction, which may result in detrimental effects on structures.This research describes a numerical approach aimed at investigating the interaction between tunnelling-induced ground deformations and framed buildings with masonry infills. This study includes experimental data obtained from geotechnical centrifuge tests and predictions of building response based on numerical analyses. The numerical model, analysed with the Finite Element method, includes the soil, the tunnel, and the framed structure with infills. It proved its capability in repr
