Net cages are mainly located on the coastal areas of Peng-hu and Ping-tung counties. Generally, there are two kinds of disasters occurred in the fish farming industries: one is caused by typhoon attack, while the other is caused by human vandalism. This paper is focus on how to prevent the damages induced by poaching or vandalism. Since high-valued fish are raised in the net cages, they are often become the targets of illegal intruders for stealing at night, especially when the net cages are lack of security system. Under such unsecured situation, entrepreneurs would not dare to invest in this industry and may keep a suspicious attitude towards it. Compare to land aquaculture, marine aquaculture is far more complicated in terms of techniques involved in production progress. Surely over-fishing has serious deplete the stock of biomass in the sea in the past decades. Recently, the skyrocketed oil price even deteriorate the fishing industry to such a level that fishing boats can only operate for a season in each year and end up losing money. However, Fisheries Agency has planned to recycle commercial fishing boats, and hopefully by doing so, this aquacultural industry will turn into a new trend in the near future. This research looks into 700 hectares of net cage park, Southern Oceanic Park, and suggests that the fishery authority turn this area into special district, adjust the fishery law, designate San-fu port as the park¡¦s operation center, finally set up a security system, then we may reduce the damage caused by unlawful activities. The geographical make-up of Liu-chiu provides ideal conditions for the present net cage area. The sea waters outside of San-fu port are also blessed with the same geographical advantage. This research looks at ¡§man-made calamities¡¨, namely vandalism and theft, so as to prevent damage and loss and protect resources and equipment. The areas chosen for this study include the surrounding sea waters of Liu-chiu aquaculture zone and the highly representative San-fu fishing port. There are also discussions on the installation of automatic alarm system in the eventual marine park. As an officer in a law enforcement administration for coastal affaires, my past contact with net cage fishermen revealed the damage and loss they have been undergoing and their sense of helplessness. On top of that, relevant documents turned out to be insufficient. Therefore, this research aims to figure out a way to fill this security gap by integrating public power from governmental services with protection and safety solutions on the part of individuals. To put this initiative to work, it is necessary to map out a special marine park where security mechanism could be automatically triggered by local facilities. This will then allow public power and personal endeavor to work simultaneously in the special zone and prevent any illegal activities. With its high applicability and pertinence, the eventual security system will hopefully entice more entrepreneurs, thus maintaining a sound net cage aquaculture.

Le Paléoprotérozoïque est une période charnière de la métallogénie de l'uranium marquée par l'oxyatmoversion (le GOE, ca. 2,4 Ga) rendant possible une mobilité sans précédent de l'U en solution. Dans ce contexte, cette thèse porte sur l'étude de deux types de minéralisations provenant du district de Cage (Québec). Une première minéralisation « stratoïde » à U, Ba, V, Mo, Pb, Zn, sans Th localisée dans des séries carbonatées paléoprotérozoïques du Groupe du Lake Harbour métamorphisées pendant l'orogène Torngat (1,87-1,77 Ga). La minéralisation uranifère s'est formée par l'interaction entre un fluide météorique oxydant, qui en percolant le long de la plateforme carbonatée s'est enrichi en U au contact de matériel volcanique, et des minéralisations de type MVT préalablement déposés avec de la matière organique. Une seconde minéralisation à U-Th portée par des « skarn s.l. » est liée à des pegmatites ainsi que des fluides hydromagmatiques ayant une source commune profonde provenant de la granutilisation de l'Archéen sur lequel repose le Groupe de Lake Harbour. Les résultats de cette thèse contribuent à une meilleure connaissance des processus qui ont conduit à l'enrichissement en U de la croute paléoprotérozoïque, en mettant en évidence deux nouvelles possibilités : - Des concentrations liées au fonctionnement de plateforme carbonatées enrichies en sulfates après le GOE, en contexte de rifting, au cours de la dislocation des méga-continents formés à la fin de l'Archéen ; - Des concentrations liées aux métamorphismes UHT qui granutilisent la CCI pendant le processus d'amalgamation du supercontinent Nuna. / Paleoproterozoic is a key transitory period for Uranium deposits. The appearance of an atmosphere with free oxygen (GOE, ca. 2,4 Ga), event generally know as oxyatmoversion, made it possible U mobility via aqueous solutions. The present thesis deals with two types of uranium mineralizations that are related to this period (Cage district, Québec). The first “stratoïd” deposit is characterized by U, Ba, V, Mo, Pb, Zn, mineralizations without Th. Host-rocks are carbonate paleoproterozoic series, from Lake Harbour Group, that were metamorphosed during the Torgnat orogen (1,87-1,77 Ga). The percolation along the carbonate platforms of an oxidized meteoric fluid lead to Uranium deposits by interaction with U enrichment from volcanic material, and organic rich MVT type mineralization. The second U-Th mineralization is hosted by “skarn s.l.”. It is related to pegmatites and hydro-magmatic fluids with the same deep origin: granutilization of archean terranes on which Lake Harbour Group is situated. The present work permits a better comprehension of U enrichment of paleoproterozoic crust with two new hypotheses: - Ore concentrations related to the carbonate platforms, enriched in sulfate, during rifting and dislocation of mega-continents at the end of Archean times; - Ore concentrations related to UHT metamorphism and granutilization of continental crust during hypercollision and formation of the so-called Nuna continent.

<p>Tidig upptäckt och intervention är av stor vikt när det gäller att komma till rätta med alkoholproblem. För att identifiera vilka som har alkoholproblem använder man sig inom vården av screeninginstrument.

My thesis is about the dualistic connotation of the cage. The original intention of a cage is to create a boundary to enclose a target. However, a cage has a positive intent for protection. With this idea, I created kinetic sculpture and installation pieces referencing cages. While I understand the negative association of cages, I made them seductive through the careful consideration of lightness, fragility, and sheen. I have been exploring forms and material qualities to express the contradictory connotation of cages. Most of my work is made of wire because I have a great interest in the delicate nature of wirework. I use silver as my primary material for its impression of duality. Silver is desirable with its economic worth, but also it attracts our senses with its ability to be shiny and reflective. Conversely it could be manipulated to have a cold distant industrial look. In the end I wanted my audience to have unsettling desires.

The regulation of gene expression is the driver of cellular differentiation in multicellular organisms; the result is a diverse range of cell types each with their own unique profile of expression. Within these cell types the transcriptional product of a gene is up or down regulated in response to intrinsic and extrinsic stimuli according to its own regulatory programme encoded within the cell. The complexity of this regulatory programme depends on the requirements of the gene to change expression states in different cell lineages or temporally in response to a range of conditions. In the case of many housekeeping genes integral to the survival of the cell, this programme is simple - switch on the gene and leave it on, whereas often the required level and precision of regulatory control is much more involved and lends to subtle changes in expression. This raises many questions of precisely where and how that regulatory information is encoded and whether different biological systems encode it in the same way. This project attempts to answer these questions through the development of novel approaches in quantifying the output of this regulatory programme according to the state changes as observed from the expression profile of a given gene. Measures of complexity in gene expression are calculated over a wide range of cell types and conditions collected using CAGE, which provides a quantitative estimate of gene expression that precisely defines the promoter utilised to initiate that expression. As expected, housekeeping genes were found to be amongst the least complex, as a result of their uniform expression profiles, as well as those genes highly restricted in their expression. The genes most complex in their expression output were those associated with the presence of H3K27me3 repressive marks; genes poised for activation in a specific set of cell types, as well as those enriched in DNAse I hypersensitive sites in their upstream region but not necessarily conserved in that region. Evidence also suggests that different promoters associated with a gene contribute in different ways to its resultant regulatory complexity, suggesting that certain promoters may be more crucial in driving the regulation of some genes. This allows for the targeting of such promoters in the analysis of certain diseases implicated by changes in regulatory regions. Indeed, genes known to be associated with diseases such as leukaemia and Alzheimer’s are found to be highly complex in their expression.

Supramolecular chemistry allows the rapid formation of complex systems through self-assembly. These systems often possess unique properties not observed for conventional covalent constructs and have potential applications in areas such as sensing, drug delivery and catalysis. Metallosupramolecular container compounds have been shown to catalyse reactions with both regio- and stereo-selectivity in methods analogous to enzyme type catalysis. Separately, visible-light photoredox catalysis has recently gained considerable interest as an efficient, green and mild method for the rapid synthesis of many chemical compounds. In order to combine the favourable properties of both supramolecular catalysis and visible-light photoredox catalysis, a number of photoredox active metallosupramolecular assemblies were designed, synthesised and analysed. Initial steps were taken to stabilise a known iridium-based M6L4 luminescent cage compound to allow guest encapsulation to take place. The incorporation of isocyanide donors as strong ligands improved the stability of model compounds but synthesis of an analogous three-dimensional assembly was unsuccessful. Instead, a “complex-as-ligand” approach was taken that allowed the straight-forward formation of Pd2L4 systems from a range of photoactive iridium complexes. Importantly, unlike many other photoactive systems, the complexation to palladium did not drastically affect the photoredox properties of the constituent iridium complexes. Multiple approaches were then taken to improve both the stability and guest binding properties of the photoactive assembly in an effort to achieve supramolecular photoredox catalysis. Utilising a model system, a general method was thus developed for enhancing the association constants of neutral guests in organic solvents by switching to large, non-coordinating counter ions that provided reduced competition for the internal binding site. In combination with this increased binding affinity, a range of guest properties were adjusted by association with the hydrogen bond donor environment of the internal cavity. The encapsulation of quinone based oxidants led to unexpected and novel reaction pathways not observed in the bulk phase. As such, this work represents a significant advancement in development of metallosupramolecular systems capable of regio- and stereo-selective photoredox catalysis.

An experimental approach was taken in determining the quantum yield of Ruthenium(II) with Oxygen using two different Ru complexes. This reaction results in Ruthenium(III) and O2-. The Coulombic interactions caused by a carboxylate functional was found to increase the yield of charge separation. This was done using a diode to measure the intensity of the completed reaction over a certain time frame. The intensities were turned into concentrations. The concentration over time was used to determine the quantum yield. This information is useful in creating more efficient light emitting diodes.
