Research on crustal structure and lithosphere property in the Okinawa Trough area

A mass of geological, geophysical and geochemical data and information from the Okinawa Trough area are collected for comprehensive research in the study area from East China to Okinawa Trough and then to Ryukyu Island Are region. According to the seismic tomography result (P and S wave) and the processing result of free-air and Bouguer gravity anomaly and magnetic anomaly data in the study area, the comprehensive interpretation is carried out. The Moho depth distribution of the study area is obtained by the inversion calculation based on gravity data using the Harmonious Series method. The crust properties are analyzed. Meantime, some Cenozoic basalt data from Kuandian (NE China), Hannuoba (North China), Minxi (South China), Penghu Islands (Taiwan Strait), Okinawa Trough and Japan Island Arc regions are chosen to make the comparison research on element- isotopes. The result indicates that the lithosphere thickness in the Okinawa Trough area has obviously decreased, where a Low -velocity layer of upper-mantle has reached the Moho interface and the metasometized asthenosphere has formed. The research result on element- isotopes shows that the characteristic of the crust in the Okinawa Trough area is different from that in East China area and the Ryukyu Island Arc area. It is considered that the crust in the Okinawa Trough area belongs to the transition type, which is quite similar to the feature of the oceanic crust.

Ecological Networks in Stored Grain: Key Postharvest Nodes for Emerging Pests, Pathogens, and Mycotoxins

Wheat is at peak quality soon after harvest. Subsequently, diverse biota use wheat as a resource in storage, including insects and mycotoxin-producing fungi. Transportation networks for stored grain are crucial to food security and provide a model system for an analysis of the population structure, evolution, and dispersal of biota in networks. We evaluated the structure of rail networks for grain transport in the United States and Eastern Australia to identify the shortest paths for the anthropogenic dispersal of pests and mycotoxins, as well as the major sources, sinks, and bridges for movement. We found important differences in the risk profile in these two countries and identified priority control points for sampling, detection, and management. An understanding of these key locations and roles within the network is a new type of basic research result in postharvest science and will provide insights for the integrated pest management of high-risk subpopulations, such as pesticide-resistant insect pests.

Löydöstä muinaispuvuksi : arkeologisten tekstiilien ennallistaminen

From a find to an ancient costume - reconstruction of archaeological textiles Costume tells who we are. It warms and protects us, but also tells about our identity: gender, age, family, social group, work, religion and ethnicity. Textile fabrication, use and trade have been an important part of human civilization for more than 10 000 years. There are plenty of archaeological textile findings, but they are small, fragmentary and their interpretation requires special skills. Finnish textile findings from the younger Iron Age have already been studied for more than hundred years. They have also been used as a base for several reconstructions called muinaispuku , ancient costume. Thesis surveys the ancient costume reconstruction done in Finland and discusses the objectives of the reconstruction projects. The earlier reconstruction projects are seen as a part of the national project of constructing a glorious past for Finnish nationality, and the part women took in this project. Many earlier reconstructions are designed to be festive costumes for wealthy ladies. In the 1980s and 1990s many new ancient costume reconstructions were made, differing from their predecessors at the pattern of the skirt. They were also done following the principles of making a scientific reconstruction more closely. At the same time historical re-enactment and living history as a hobby have raised in popularity, and the use of ancient costumes is widening from festive occasions to re-enactment purposes. A hypothesis of the textile craft methods used in younger Iron Age Finland is introduced. Archaeological findings from Finland and neighboring countries, ethnological knowledge of textile crafts and experimental archaeology have been used as a basis for this proposition. The yarn was spinned with a spindle, the fabrics woven on a warp-weighted loom and dyed with natural colors. Bronze spiral applications and complicated tablet-woven bands have possibly been done by specialist craftswomen or -men. The knowledge of the techniques and results of experimenting and experimental archaeology gives a possibility to review the success of existing ancient costume reconstructions as scientific reconstructions. Only one costume reconstruction project, the Kaarina costume fabricated in Kurala Kylämäki museum, has been done using as authentic methods as possible. The use of ancient craft methods is time-consuming and expensive. This fact can be seen as one research result itself for it demonstrates how valuable the ancient textiles have been also in their time of use. In the costume reconstruction work, the skill of a craftswoman and her knowledge of ancient working methods is strongly underlined. Textile research is seen as a process, where examination of original textiles and reconstruction experiments discuss with each other. Reconstruction projects can give a lot both to the research of Finnish younger Iron Age and the popularization of archaeological knowledge. The reconstruction is never finished, and also the earlier reconstructions should be reviewed in the light of new findings.

Enhancement of fish production in Borno State with extension services

Borno State possesses great potentials for fish production both from inland fisheries and aquaculture. The socio-economic and environmental production factors are suitable for fish production. If the potential of the State were well harnessed, it would be playing significant roles in achieving self-sufficiency in fish production in Nigeria. But the situation at the moment is that its fisheries potentials are not being optimally utilized. While the inland waters of Lake Chad are currently being recklessly exploited, aquaculture development is given little or no attention. It is evident that there is a missing link between research results and the potential end users. Because information in fish production variables is a pre-requisite for fisheries development, the gap that exists between two poles must be bridged, fisheries Extension provides this important link between research result and the end users of research findings. The paper examines the importance of extension services as the key to unlock fish production information that are usually consigned to the pages of academic journals and research publications

Fundo público e assistência social: o financiamento da política de assistência social no município de Campos dos Goytacazes no período de 2004 a 2012

A dissertação apresenta um estudo sobre a constituição do Fundo Público no capitalismo contemporâneo, a partir das três grandes crises do capital do século XX. Realizaremos, para tanto, uma incursão histórica e analítica, percorrendo o início do século XX até os dias atuais, demonstrando a importância e imprescindibilidade do Fundo Público para a reprodução do capital e do trabalhador. Neste contexto, de expansão e retração da economia em nível mundial, analisaremos os rebatimentos no Brasil, a partir da contrarreforma do Estado, na apropriação e composição do fundo público brasileiro. Ao garantir a reprodução do trabalhador, o Fundo Público o faz por meio das políticas sociais, e em especial, trabalharemos a Política de Assistência Social. O objetivo deste trabalho é realizar análise sobre todos os recursos destinados ao Fundo Municipal de Assistência Social do município de Campos dos Goytacazes, que servirão para o financiamento da rede socioassistencial em âmbito municipal no período de 2004 a 2012. Analisaremos, portanto, os recursos municipal, estadual e federal, tendo como base os segintes documentos: Demonstrativo da Evolução Orçamentária e de Despesas, Relatório de Receitas Geral, Lei de Diretrizes Orçamentária e a lei Orçamentária Anual, que serão transferidos para o fundo e de que forma o poder executivo prioriza a gestão destes recursos, por meio de suas despesas. O resultado da pesquisa nos mostrou que a Política de Assistência Social é cofinanciada pelos três entes federativos, no entanto, evidenciamos grandes dificuldades para a gestão compartilhada. O município é o maior financiador desta política, entremente, seus recursos são alocados prioritariamente nos Programas de Transferência de Renda municipais e nas entidades filantrópicas, enquanto os programas federais ficam sob a responsabilidade majoritária da União. O estado neste processo, quase que esquecido, se mostra com um financiamento extremamente pontual, descontínuo e ínfimo. Dos recursos direcionados a esta política, identificamos um grande montante que não são executados, o que consideramos hoje um dos grandes desafios para a efetivação desta Política em Campos dos Goytacazes.

Beel fishery and livelihood of the local community in Rajdhala, Netrakona, Bangladesh

Baseline survey and Participatory Rural Appraisal (PRA) during January 2003 to December 2004 on the fishing community revealed that unregulated fishing, use of destructive fishing gears, poaching of fishes, difficulties encountered in enforcing fisheries regulation and the helplessness of fishers to find alternative sources of income during banned fishing period (June to October) were the major management problems. CBFM (Community Based Fisheries Management) system as an alternative management strategy has been introduced to ensure active participation of the target group-the poor fishers living around the beet who were previously deprived to get access to the beet. Establishing a leasing system for controlled access, ensuring greater user-group participation through equitable distribution of all resource benefits among members, attempting to enforce penalties for illegal fishing linked with surprise checks to enforce management regulations are some of the recent steps taken by the BMC (Beel Management Committee). Chapila fish intake by the community was 31.25 g/head/day before stocking the beel by carp fingerlings. After stocking, they consumed chapila as fish protein from 8.33 g to 20.8 g/head/day during the fishing season (November to May) indicating that due to introduction of carp fingerlings, chapila production has been decreased in 2003-2004. About 77.5% families around the beel were found to be dependent directly and/or indirectly on chapila and other indigenous fishes of the beel for their livelihood, through fishing, marketing and other activities like net and boat preparation and nets mending etc. Particularly fishers' families were found to face serious problem during non-fishing period like June to October for their livelihood. Analyzing the present research result it was also observed that other than declination in biodiversity, the fishing pressure on promising chapila of the beel was found high and that is why the production of chapila has also been decreased. To get sustainable chapila production from the heel, it is suggested to ensure successful spawning and recruitment as juveniles, and hence the chapila should be undisturbed during its breeding period from March to July, and fishing pressure on the same species needs to be reduced for obtaining sustainable fish production.

Mitochondrial d-loop sequence variation and phylogeny of gobiobotine fishes

The mitochondrial DNA control region is amplified and sequenced from 8 genera and 10 species of gobiobotine fishes. The phylogenetic tree of Gobiobotinae and some representative species of other Cyprinid subfamilies obtained by the method of neighborhood joining, maximum likelihood and maximum parsimony with Danio rerio as an outgroup indicates that Gobiobotinae fishes are a monophyletic group which is close to Gobioninae subfamily. Gobiobotinae should be included into subfamily Gobioninae in terms of phylogenetic analysis. The research result supports that Gobiobotinae can be divided into genus Xenophysogobio and Gobiobotia. Xenophysogabio is the most primitive genera in the subfamily.

松辽盆地古龙地区葡萄花油层组沉积成岩相研究

The sediment and diagenesis process of reservoir are the key controlling factors for the formation and distribution of hydrocarbon reservoir. For quite a long time, most of the research on sediment-diagenesis facise is mainly focusing on qualitative analysis. With the further development on exploration of oil field, the qualitative analysis alone can’t meet the requirements of complicated requirements of oil and gas exploreation, so the quantitative analysis of sediment-diagenesis facise and related facies modling have become more and more important. On the basis of the research result from stratum and sediment on GuLong Area Putaohua Oil Layer Group, from the basic principles of sedimentology, and with the support from the research result from field core and mining research results, the thesis mainly makes the research on the sediment types, the space framework of sands and the evolution rules of diagenesis while mainly sticking to the research on sediment systement analysis and diagenetic deformation, and make further quantitative classification on sediment-diageneses facies qualitatively, discussed the new way to divide the sediment-diagenesis facies, and offer new basis for reservoir exploration by the research. Through using statistics theory including factor analysis, cluster analysis and discriminant analysis, the thesis devided sediment-diagenesis facies quantitatively. This research method is innovative on studying sediment-diagenesis facies. Firstly, the factor analysis could study the main mechanism of those correlative variables in geologic body, and then could draw a conclusion on the control factors of fluid and capability of reservoir in the layer of studying area. Secondly, with the selected main parameter for the cluster analysis, the classification of diagenesis is mainly based on the data analysis, thus the subjective judgement from the investigator could be eliminated, besides the results could be more quantitative, which is helpful to the correlative statistical analysis, so one could get further study on the quantitative relations of each sediment-diagenesis facies type. Finally, with the reliablities of discriminant analysis cluster results, and the adoption of discriminant probability to formulate the chart, the thesis could reflect chorisogram of sediment-diagenesis facies for planar analysis, which leads to a more dependable analytic results.According to the research, with the multi-statistics analysis methods combinations, we could get quantitative analysis on sediment-diagenesis facies of reservoir, and the final result could be more reliable and also have better operability.
