Petrography, Petrochemistry and petrogenesis of Huronian volcanic rocks of the Elliot Lake region, Ontario

In the Elliot lake region of northern Ontario, Yolcanlc lava piles represent the lowermost units of the Huronian SUpergroup. These rocks general1y trend east-west and belong to the Elliot lake Group. They are s1tuated on the north and south limbs or the QuIrke lake Syncline. The volcanIc rocks of this study contain a secondary minerai assemblage consisting of actinolite, biotite, chlorIte, eptdote/cllnozoislte tttanomagnettte and calcite characteristic of greenschist metamorphism. Compilation of data suggests that metamorphism of the volcanic rocks proceeded between 325- and 425-C and between 2.4 and 4.7 kb. Geochemtcally these lavas represent tholeiitic and calc-alkaline assemblages. The tholeiites are character1sttcally enriched tn Fe and Tt and consist mainly of basalts, basaltic andesites and andesites. These rocks are believed to have formed by the partIal melting of a peridottte source at low P-T. In contrast, the calc-alkaline rocks are depleted in Fe and TI, but show a signIficant enrichment In 51 and Zr; andesIte Is the major rock type for thIs assemblage. I·t Is postUlated that the calc-alkalIne sU1te of rocks was the result of eIther the partIal meltIng of abasaltic·magma at shallow depth, or the melttng of s1al1c crustal materIal due to the added we1ght of tholeiitIc material on an unstable crust and to downwarplng processes Inttlated by convection cells.

Self-Regulated Learning and Children At-Risk for Learning Disabilities: Using Motivational Tactics to Support "Reading Rocks!"

This project explored self-regulation among children impacted by leaming disabilities. More specifically, this thesis examined whether a remedial literacy program called Reading Rocks! offered by the Leaming Disabilities Association of Niagara Region, provided participating children opportunities to set goals, develop strategies to meet these goals, and provide intemal and extemal feedback- all processes associated with a model of self-regulated leaming as pioneered by Butler and Winne (1995) and Winne and Hadwin (1999). In this thesis, I triangulate the data through the combination of three different methodologies. Firstly, I describe the various elements of the Reading Rocks! program. Secondly, I analyze the data gathered through three semi-structured interviews with three parents of children that participated in the Reading Rocks! program to demonstrate whether the program provides opportunities for children to self-regulate their learning. Thirdly, I also analyze photographic evidence of the motivational workstation boards created by the tutors and children to further illustrate how Reading Rocks! promotes self-regulatory processes among children.

Reading Rocks Junior: A Mixed-Methodological Study of the Efficacy and Accessibility of an Emergent Literacy Intervention

This thesis explored early literacy development in young vulnerable readers. More specifically, this thesis examined an emergent literacy program called Reading Rocks Junior offered by the Learning Disabilities Association of Niagara Region to children four- to six-years of age living in low socioeconomic status communities. Three methodologies were combined to create a rich and complete picture of an effective and accessible literacy program. First of all, a description of the Reading Rocks Junior program is outlined. Secondly, quantitative data that was collected pre- and post- program was analyzed to demonstrate achievement gains made as a result of participating in the program. Finally, qualitative interviews with the program coordinator, the convener of the agency that funded Reading Rocks Junior and three parents whose children participated in the program were analyzed to determine the contextual factors that make Reading Rocks Junior a success.

Motivation among reluctant readers: Capturing the goal setting experience in the 'Reading Rocks' program

This study explored goal setting among children with reading disabilities. Of particular focus was the goal setting experience of participants in a literacy-based program, titled “Reading Rocks”. Reading Rocks, offered by the Learning Disabilities Association of Niagara Region (LDANR), supports children with reading disabilities to become more confident readers. The program aims to strengthen literacy skills among vulnerable readers. Another essential component of the program targets children’s reading motivation through goal setting, a recognized strategy for increasing motivation. I outline the importance of reading, followed by exploring children’s reluctance to read. Goal setting is examined as an opportunity to increase motivation among reluctant readers. My research included a qualitative case study of one child-tutor pair in the program. I utilized a think-aloud protocol, a photo elicitation interview, and researcher observations to collect my data. Lastly, I triangulated the data to analyze how children in Reading Rocks experience goal setting.

Waxing Ornamental : Reading a Poetics of Excess in Virginia Woolf’s Orlando and Djuna Barnes’s Nightwood

Ce mémoire de maîtrise porte sur une poétique de l’excès dans Orlando de Virginia Woolf et Nightwood de Djuna Barnes comme une stratégie combattant la tendance qu’a le modernisme à dévaloriser l’écriture des femmes comme étant trop ornementale. J’expose comment Ezra Pound, T.S. Eliot, et Wyndham Lewis tentent de récupérer la notion du détail afin d’affirmer une poétique masculin. Je fais appel également aux oeuvres de l’architecte autrichien Adolf Loos qui souligne sa dénonciation de l’ornement comme régressif. Dans Orlando et Nightwood, je considère l’excès associé au corps. Je soutiens que, dans ces textes, les corps dépassent les limites de la représentation moderniste. Je considère aussi comment Orlando et Nightwood font apparaître la narration comme ornement et écrivent excessivement l’histoire et le temps. Pour conclure, je propose une façon de lire l’excès afin de reconceptualiser le potentiel de production de la signification dans des textes modernistes.

Prospects of Marketing the Indigenous Ornamental Fishes of Kerala

In this study prospects of marketing the indigenous ornamental fishes of kerala, point out that the export market, consumer preferences in the domestic ornamental fishes, SWOT (strength weakness opportunities and threats) analysis etc. The study notes that the product indigenous ornamental fishes are mostely marketed by exporters and suppliers rather than the retail aquarium shopkeepers. The research findings on the attributes of indigenous ornamental fishes that matches customers preference in aquarium fish.SWOT analysis was carried out to classify the results of the study into strengths,weakness,opportunities and threats faced by the ornamental fish industry in kerala. The marketers in the study show less market perception compaired to the exporters of India. Rather than market survey, interest and experience and raw materials availability inspires them. The developments for large scale marketing have to be carried out, ensuring the sustainable exploitation of the wild fish population by adopting conservation measures such as breeding programmes, quota implementation, setting up of natural sanctuaries to protect the natural resource of ornamental fishes.

Metamorphism and Fluid Inclusion Studies of Charnockites and Associated Rocks from the Madurai Granulite Block , Southern India with Special Reference to Graphite Mineralization

The present research is aimed at studying the charnockites and associated rocks of the Madurai Granulite Block (MGB), especially in terms of their field settings, texture, mineralogy, and mineral chemistry analyzing their petrogenesis with the help of thermobarometrical studies and geochronological constraints. The mechanism of charnockitization by the influx of CO2 rich fluids and its relation to the graphite mineralization is actually a matter of discussion and study. The objectives of the present study are, to delineate petrological and structural relationship of charnockites and associated gneissic rocks, to study the field and petrogenetic aspects of graphite mineralization in the MGB, to establish and re-evaluate the P-T conditions of formation of the rocks with the aid of thermbarometric computations and to compare with the earlier studies, characterization of graphite with XRD, Raman spectroscopy and isotope studies together with a search in to its genesis and its relation to the high-grade metamorphism of the terrain, to evaluate the role of CO2 bearing fluids in the processes of charnockitization as well as in the genesis of graphite within the high-grade terrain and to delineate the metamorphic geochronology of selected rocks using ‘monazite dating’ technique with EPMA.

Economics of Ornamental Fisheries in Kerala

Comprehensive studies integrating production, consumption and marketing of ornamental fishes were never conducted in the past in Kerala and this study is an attempt to highlight the dynamics in a systematic manner by making a primary empirical study. The advantages of such an approach are many. First, the study entails detailed empirical data under a given time frame on various inter linked economic activities in ornamental fisheries sector. Second, the study tries to improve upon the previous discipline-bound studies by adopting an integrated approach. As Kerala has diverse ecological and climatic conditions, case studies on various ornamental fish production systems help identifying suitable culture practice for selected environmental conditions. One of the major conclusions of this study as explained in the concluding chapter is that although Kerala is blessed with favourable geographic and climatic conditions needed for developing ornamental fishery, diverse local conditions and requirements contain adopting modern methods of enterprise development.Consumer studies conducted would help to identify the demand of ornamental fishes and the factors leading to it. Market studies would help in understanding the forces behind domestic market, which is very promising, but neglected. Viability studies throw light on the economic performance of both the production systems and the trading units of ornamental fishes. Despite the economic significance of ornamental fisheries industry, its development has been constrained due to various bio-technical, cultural, socio-economic, organisational and above all, institutional and policy failures. The outcome of the study would identify constraints facing the industry and institutional arrangements for development.

Resource abundance and Survival of indigenous ornamental fishes of central Kerala with emphasis on handling and packing stress in Puntius filamentosus(VALENCIENNES)

This thesis Entitled Resource abundance and survival of indigenous ornamental fishes of central kerala with emphasis on handling and packing stress in puntius filamentosus (valenciennes).Kerala state is endowed with 41 west flowing and three east flowing rivers originating in the Western Ghats. These rivers and their vast network of tributaries and distributaries harbour rich and diversified fish fauna. Most of the freshwater fishes available in Kerala are highly appreciated as ornamental fishes in the national and international markets.Today the ornamental fish industry is one of the largest industries all over the world. The demand for ornamental fishes has been increasing steadily with the enlargement of the industry, such that the current demand for indigenous ornamental fishes have exceeded the supply. This has led to serious concern about the resources available in the country that can be utilised judiciously for the economic benefit of the state. With an aim to fill up the lacuna, a database of freshwater ornamental fishes of Kerala was created as part of the present study. Ornamental fishes destined for export marketing should thrive well in the aquarium conditions.The study reiterates fishes caught from different environmental conditions and feeding habits have a greater ability to adapt and acclimatise to an entirely new environment and food habits. Marketing studies based on the statistics available with Marine Products Export Development Authority show that these species are not being exported at the required level over the past 6 years, when compared to the availability in the water bodies of Kerala. Sustainable utilisation of these resources from the wild using modern management principles and code of conduct for responsible fishing are advisable until captive breeding technology is popularised.

Prevalence, distribution and drug resistance of motile aeromonads in freshwater ornamental fishes

The objective of the present study was to assess the prevalence of various motile aeromonads in freshwater ornamental fishes and to elucidate the antibiogram and beta hemolytic activity among the isolates. A total of 120 ornamental fish samples were screened and analyzed for Aeromonas spp. Motile aeromonads were isolated from 37.5% of the ornamental fish samples. Various species of motile aeromonads such as Aeromonas caviae, Aeromonas hydrophila, Aeromonas jandaei, Aeromonas schubertii, Aeromonas sobria, Aeromonas trota and Aeromonas veronii were detected. All the isolates were sensitive to ceftazidime, chloramphenicol, ciprofloxacin and gentamicin. Multiple antibiotic resistance was observed in 58% of the isolates.

Distribution, Extracellular Virulence Factors and Drug Resistance of Motile Aeromonads in Fresh Water Ornamental Fishes and Associated Carriage Water

During last decades there has been a continuous growth of aquaculture industries all over the world and taking into consideration the spurt in freshwater ornamental fish aquaculture and trade in Kerala, the present study was aimed to assess the prevalence of various motile Aeromonas spp. in fresh water ornamental fishes and associated carriage water. The extracellular virulence factors and the antibiogram of the isolates were also elucidated. Various species of motile aeromonads such as Aeromonas caviae, A. hydrophila, A. jandaei, A. schubertii, A. sobria, A. trota and A. veronii were detected. Aeromonas sobria predominated both fish and water samples. Extracellular enzymes and toxins produced by motile aeromonds are important elements of bacterial virulence. The production of extracellular virulence factors - proteases, lipase, DNase and haemolysin by the isolates were studied. All the isolates from both fish and water samples produced gelatinase and nuclease but the ability to produce lipase, caseinase and haemolysins was found to vary among isolates from different sources. Among the 15 antibiotics to which the isolates were tested, all the isolates were found to be sensitive to chloramphenicol, ciprofloxacin and gentamicin and resistant to amoxycillin. Local aquarists maintain the fish in crowded stressful conditions, which could trigger infections by the obligate/ opportunistic pathogenic members among motile aeromonads

Virulence Potential And Antibiotic Susceptibility Pattern Of Motile Aeromonads Associated With Freshwater Ornamental Fish Culture Systems: A Possible Threat To public Health

Aeromonas spp. are ubiquitous aquatic organisms, associated with multitude of diseases in several species of animals, including fishes and humans. In the present study, water samples from two ornamental fish culture systems were analyzed for the presence of Aeromonas. Nutrient agar was used for Aeromonas isolation, and colonies (60 No) were identified through biochemical characterization. Seven clusters could be generated based on phenotypic characters, analyzed by the programme NTSYSpc, Version 2.02i, and identified as: Aeromonas caviae (33.3%), A. jandaei (38.3%) and A. veronii biovar sobria (28.3%). The strains isolated produced highly active hydrolytic enzymes, haemolytic activity and slime formation in varying proportions. The isolates were also tested for the enterotoxin genes (act, alt and ast), haemolytic toxins (hlyA and aerA), involved in type 3 secretion system (TTSS: ascV, aexT, aopP, aopO, ascF–ascG, and aopH), and glycerophospholipid-cholesterol acyltransferase (gcat). All isolates were found to be associated with at least one virulent gene. Moreover, they were resistant to frequently used antibiotics for human infections. The study demonstrates the pathogenic potential of Aeromonas, associated with ornamental fish culture systems suggesting the emerging threat to public health
