Abstract:

In Stockholm, Sweden, diffuse emissions of metals have become the dominating source of copper towater. This thesis work made an attempt to link the source of copper emission and the fate of the copper in a lake. These models have been applied in the case study of Lake Råcksta Träsk and its urban drainage area in Stockholm, Sweden. The source analysis model has been adopted and modified from Cui et al (2008) and Sörme and Lagerkvist (2002) and the basic fate model has been taken and modified from Håkanson (2006) and Lindström and Håkanson (2001).

Abstract:

In recent years, stringent world-wide regulation of copper in drinking water, wastewater discharge and sludge has prompted utilities to carefully evaluate copper sources and sinks, benefits and detriments, and mitigation. This work compiled the individual efforts of researchers and utilities to provide a basis for holistic decision-making. Mass balances suggest that between 14-61% of copper in wastewater originates from home plumbing. Dosing of pure copper sulfate "root killer" by consumers, which is of unlikely value, accounted for up to 27% of copper inputs. Removal of copper in wastewater t

Laser copper plasma sources are a compact, economical means of producing high intensity x-rays at the correct wavelengths for x-ray lithography. Copper debris in the form of vapor, ions, dust, and high-speed particles is an unwanted byproduct of the laser copper plasma technique. Improved methods for debris mitigation are essential for production x-ray lithography using laser copper plasma sources.

A key challenge facing the nuclear fusion community is how to design a reactor that will operate in environmental conditions not easily reproducible in the laboratory for materials testing. Finite element analysis (FEA), commonly used to predict components’ performance, typically uses idealised geometries. An emerging technique shown to have improved accuracy is image based finite element modelling (IBFEM). This involves converting a three dimensional image (such as from X ray tomography) into an FEA mesh. A main advantage of IBFEM is that models include micro structural and non idealised manu

Copper (Cu) is an essential micronutrient for plants and many microorganisms, playing a key role in electron transport during photosynthesis, lignin formation and cell wall metabolism. However, when Cu is present at elevated concentrations it can cause toxicity with impacts on the growth, reproduction and survival of aquatic and terrestrial organisms. The biogeochemical cycle of Cu in aquatic and terrestrial environments can be influenced by numerous biological (e.g. root rhizosphere) and physicochemical (e.g. redox, pH) properties.

Abstract:

This item is only available electronically.<br>Many isotope proxies have been applied to study the prosperous iron oxide copper gold (IOCG) province in the eastern Gawler Craton (E.G.C) and Au mineralised region of the cental Gawler Craton (C.G.C), in Southern Australia. Yet, copper isotope proxies- an indicator for low temperature fluid flow and sulfide mineralisation- have yet to be applied to the region. In this study, purification techniques using automatic column chromatography were demonstrated during separation of Cu from matrix elements. Cu isotopes – 65Cu & 63Cu – were used to unde

The research area covered the farmlands with irrigation of high pollution potentials in the Taoyuan area. Through transmission channels such as sediment and water, possible sources of pollution in the target groups were obtained to build a conceptual model for the pollution sample area. In this study, during the farmland soil investigation, 350 soil samples were retrieved. Among them, 202 are higher than the control standards according to the laws and regulatio

碩士<br>國立交通大學<br>顯示科技研究所<br>94<br>The insulator surface treatment transforms the hydrophilic SiO2 surface to hydrophobic one that is more suitable for organic materials deposition. Organic thin-film transistors (OTFTs) modified by poly(��-methylstyrene) (P�埒S) exhibit a high mobility (0.5 cm2/Vs ) with a high on/off ratio ( > 106 ). Copper phthalocyanine (CuPC) has been used as the contact buffer layer to improve the device performance of organic thin-film transistors (OTFTs). By incorporating with 10 nm CuPC, the contact resistance was decreased to 70%, deduced from line-transfer method. The m

A copper rod, 400mm in length and 38mm in diameter, is heated by an electrical heater with a pulse-width-modulated (PWM) solid state relay (SSR) control module from one boundary point. The temperature distribution of the copper rod is sampled and collected into a TMS320LF 2407A digital signal processor (DSP) manufactured by Texas Instruments (TI). The data is then plotted and analyzed by using Matlab software packages. In addition, the copper heat conduc

The high abundance of sulfur in these ligands has resulted to be the preferred complexes for the synthesis of metal sulfide nanoparticles. All the prepared complexes were characterized using techniques such as IR and 1HNMR spectroscopy, elemental analysis, and thermogravimetric analysis. A

Copper cable theft (CCT) has a devastating effect on the South African economy, and essential services such as TELKOM, ESKOM AND TRANSNET have been seriously disrupted, due to CCT. This dissertation focuses on the value of the cell phone record as a source of intelligence during (CCT) investigations. The cell phone industry is growing each year, and millions of people worldwide possess a cell phone. Some of these people are involved in criminal activities – which mean that cell phones, with their advanced capabilities, hold evidence which relates to crime. The activation of cell phone activity

All of these products were characterized by 1H NMR, 13C NMR and 31P NMR spectroscopies. There are three phosphine molecules bonding with the Cu atom.
