Abstract:

Recognition of physical and mental responses to stress is important for stress assessment and management as its negative effects in health can be prevented or reduced. Wearable technology, mainly using electroencephalogram (EEG), provides information such as tracking fitness activity, disease detection, and monitoring neurologicalstates of individuals. However, the recording of EEG signals from a wearable device is inconvenient, expensive, and uncomfortable during normal daily activities. This study introduces the application of tensor decomposition of non-EEG data for visualizing and classify

Abstract:

In this study, anisotropic shells of revolution subject to symmetric and unsymmetrical static loads are analysed. In derivation of governing equations to be used in the solution, first order transverse shear effects are included in the formulation. The governing equations can be listed as kinematic equations, constitutive equations, and equations of motion. The equations of motion are derived from Hamilton&rsquo<br>s principle, the constitutive equations are developed under the assumptions of the classical lamination theory and the kinematic equations are based on the Reissner-Naghdi linear sh

The goal of this study was to compare different methods to decompose the zinc ferrite from the waste streams of steel making. The samples were acquired from SSAB Raahe blast furnace and converter flue gas scrubbers and Outokumpu Tornio Works bag filters EAF1, EAF3, AOD and CRK. Sludges and dusts contain significant amounts of zinc in form of zinc oxide and zinc ferrite. Zinc ferrite is highly stable compound which makes recovery of the zinc difficult. The zinc could be recovered and recycled as a valuable material and the iron rich material could be fed back to process. New method was experime

An investigation into the microwave assisted remediation of organic containing aqueous solutions has been conducted. Tri-n-butyl phosphate (TBP), the nuclear thel reprocessing solvent, and its diluents, are known to be responsible for the formation of interfacial deposits (cruds) in the alkali solvent wash stage of the Purex process for reprocessing spent nuclear fuel. The presence of cruds in the process is managed by regular wash out and the collected cruds are separated from aqueous washings and stored. Chemical oxidation of the cruds is one way of destroying them. This project explored mic

Abstract:

Headwaters, which are the most common stream order in the landscape, are mostly dependent on energy produced in the terrestrial system, largely consisting of leaf litter from riparian vegetation. The aim of this study was to investigate the decomposition in headwaters of leaf litter from three native (alder, birch, spruce) and one non-native (lodgepole pine) species and how decomposition responds to changes in the environment. Further, microbial and shredder influences on leaf-litter decomposition and aquatic decomposer ability to adapt to non-native species was investigated. By using field-da

Abstract:

I investigated the drivers of nutrient cycling by heterotrophic microbes during leaf decomposition in streams. My research addressed two overarching questions: 1) how do exogenous and endogenous factors interact to drive microbial nitrogen (N) cycling during organic matter decomposition in stream ecosystems, and 2) what affect will the global increase in biologically active N have on these factors and resulting fluxes? I conducted studies in natural streams and laboratory mesocosms to address these questions and used general stoichiometric theory to conceptualize diverse microbial assemblages

Abstract:

This study investigates the effects of forestry on leaf litter decomposition in small forest streams. Riparian forest, that is the land closest to the stream, maintain shading, water temperature and energy supply through litter fall. If the riparian zone is deforested, many riparian functions important for the integrity of the stream ecology, hydrology and biogeochemistry can be lost or modified. Leaf litter decomposition can be used as an integrated measure of the physical and biological changes following forestry perturbations. This study was conducted in 11 northern and 12 southern Swedish

Abstract:

Forested mountain watersheds provide essential resources and services (e.g., water supply) to downstream ecosystems and human communities. Fast-growing mountainside residential development not only modifies the terrestrial system but also aquatic systems by changing the nutrient input from the terrestrial to aquatic. However, the impacts of mountainside residential development on stream ecosystems are complex because interactions between in- stream process and hillslope soils control in-stream nutrient dynamics, and it is difficult to experimentally study these interactions at broad spatial sc

Abstract:

Forested headwater stream ecosystems are important integrators of terrestrial and aquatic systems and their function depends greatly on water availability. In the southern Appalachians, models of future climate change predict alterations to the timing and intensity of storms such that most precipitation may be relegated to winter and spring. During the summer and fall, relatively less precipitation will translate to lower stream flows in systems that rarely experience such a lack of water. Given these predicted changes to the hydrologic cycle, I experimentally reduced flow to downstream sectio

Abstract:

碩士<br>國立臺灣科技大學<br>化學工程系<br>92<br>The heterogeneous photocatalytic degradation of the gas-phase acetone were performed by using UV/TiO2 process in a continuous flow annular photoreactor with TiO2 thin film which was coated on quartz tube. In order to investigate the influence of removal and mineralization of acetone, the experiments were carried out under various UV light intensity, initial concentrations of reactant, oxygen dosage, retention time and humidity. In order to model the removal of acetone by UV/TiO2 process at various operation conditions, a design equation was developed

Abstract:

abstract: Dissolved organic matter (DOM) is an important part of aquatic foodwebs because it contains carbon, nitrogen, and other elements required by heterotrophic organisms. It has many sources that determine its molecular composition, nutrient content, and biological lability and in turn, influence whether it is retained and processed in the stream reach or exported downstream. I examined the composition of DOM from vascular wetland plants, filamentous algae, and riparian tree leaf litter in Sonoran Desert streams and its decomposition by stream microbes. I used a combination of field obser

Tese de doutoramento em Biologia, especialidade de Ecologia, apresentada à Faculdade de Ciências e Tecnologia da Universidade de Coimbra<br>Leaf decomposition is a basic ecosystem process in low order streams, mainly carried out by a particular group of fungi, aquatic hyphomycetes (AH), and invertebrate detritivores. In this thesis, the main goal was to investigate how and to what extent fungal diversity species relates to the stream’s key functional parameter: leaf decomposition. In Chapter 2, I tested the relative importance of substrate quality in the establishment of AH assemblages a

Abstract:

碩士<br>靜宜大學<br>生態人文學系<br>103<br>The purpose of this study is aimed to explore the role of shredders on leaflitter decomposition in three forested streams of Taiwan, which is located in north（the Happen Creek）, central（the Houpeiken Creek）, and south（the Lanren Creek）of Taiwan. The leaf litter of zuihmachilu（Machiluszuihensis）,the common riparian vegetation of the three streams, was used as material for the decomposition experiment. The leaf litter of zuihmachilu was place in the litter bag with two different mesh sizes, coarse mesh with 10mm and fine with 250μm. For coarse mesh bag, the breakdo

博士<br>國立臺灣科技大學<br>化學工程系<br>95<br>The main objective of this study is to develop a simple, energy-efficient, photoreactor for operating at room temperature. In this study, the photoreactor type included a differential-type optical fiber reactor, annular photoreactor and new optical fiber reactor. Gaseous 2-propanol (isopropanol, IPA), trichloroethylene (TCE) and benzene were chosen as the target compound in this study because IPA, TCE and benzene were common indoor air pollutants.
