Polygonal faults and their implications for hydrocarbon reservoirs in the southern Qiongdongnan Basin, South China Sea

The Polygonal faults were identified in Qiongdongnan Basin, South China Sea, by using the technique of time coherent slice and horizon flattening of high-resolution 3D seismic data. These polygonal faults occur in three tiers of the upper Meishan Formation and the Huangliu Formation. The faults have lengths of 150-1500 m, spacings of 50-3000 m, throws of 10-40 m and dips of 50-90 degrees. Tectonic evolution in the Qiongdongnan Basin can be divided into a rifted stage and a post-rifted stage. Tectonic faults are widely distributed in the rifted sequences, but are not well developed in the post-rifted stage. Few faults in the post-rifted sequences might suggest the absence of a migration pathway for hydrocarbon or other fluids. However, the existence of polygonal faults in the post-rifted sequences can serve as the pathway and promote the hydrocarbon migration and accumulation in the Qiongdongnan Basin during the post-rifted stage.

Mean sea surface heights of the South and East China Seas from ocean circulation model and geodetic leveling

The mean sea surface heights (sea surface topography) of the South China, East China, Yellow and Bohai Seas are derived from an ocean general circulation model and surface air pressure. The circulation model covers the global oceans, with fine grid (1/6degrees) covering the East Asian marginal seas and coarse grid (31) covering the rest part of the global oceans. The result shows that the China 1985 National Altitude Datum is 24.7 cm above the me-an sea surface height of the world oceans. The mean sea surface in the coastal ocean adjacent to China is higher in the south than in the north. Intercomparison of the model results with the geodetic leveling measurements at 28 coastal tidal stations shows a standard deviation of 4.8 cm and a fitting coefficient of 95.3%. After correction through linear regression, the standard deviation is reduced to 4.5 cm. This indicates that the accuracy of model results is sufficient for practical application. Based on the model results, the mean sea surface heights for the study area with a resolution of 1/6 degree are given. This result also links the mean sea levels at islands with those on the mainland coast and gives the mean sea surface heights at tidal stations in the Taiwan Island, the Dongsha Islands, the Yisha Islands and the Nansha Islands relative to the China 1985 National Altitude Datum.

EAWM-related air-sea-land interaction and the Asian summer monsoon circulation

Based on the data analysis, this study further explores the characteristics of East Asian winter monsoon (hereafter, EAWM, for brevity) as well as the related air-sea-land system, and illustrates how and to what degree anomalous signals of the subsequent Asian summer monsoon are rooted in the preceding EAWM activity. We identified an important air-sea coupled mode, i.e., the EAWM mode illustrated in Section 3. In cold seasons, strong EAWM-related air-sea two-way interaction is responsible for the development and persistence of the SSTA pattern of EAWM mode. As a consequence, the key regions, i.e., the western Pacific and South China Sea (hereafter, SCS, for brevity), are dominated by such an SSTA pattern from the winter to the following summer. In the strong EAWM years, the deficient snow cover dominates eastern Tibetan Plateau in winter, and in spring, this anomaly pattern is further strengthened and extended to the northwestern side of Tibetan Plateau. Thus, the combined effect of strong EAWM-related SSTA and Tibetan snow cover constitutes an important factor in modulating the Asian monsoon circulation. The active role of the EAWM activity as well as the related air-sea-land interaction would, in the subsequent seasons, lead to: 1) the enhancement of SCS monsoon and related stronger rainfall; 2) the northward displacement of subtropical high during Meiyu period and the related deficient rainfall over Meiyu rainband; 3) above-normal precipitation over the regions from northern Japan to northeastern China in summer; 4) more rainfall over the Arabian Sea and Northeast India, while less rainfall over southwest India and the Bay of Bengal. The strong EAWM-related air-sea interaction shows, to some degree, precursory signals to the following Asian summer monsoon. However, the mechanism for the variability of Indian summer monsoon subsequent to the strong EAWM years remains uncertain.

Numerical simulation of principal tidal constituents in the South China Sea, Gulf of Tonkin and Gulf of Thailand

The principal tidal constituents M-2, S-2, K-1 and O-1 in the South China Sea, Gulf of Tonkin and Gulf of Thailand are simulated simultaneously using the numerical scheme of Kwok et al. (1995 Proceedings of the 1st Asian Computational Fluid Dynamics Conference, pp. 16-19). The average differences between the computed and observed harmonic constants are mostly within 5 cm and 10 degrees for amplitudes and phase-lags, respectively. The simulated tidal regimes in the present model are believed to be more accurate than the previous numerical results. Our studies confirm that a clockwise rotating M-2 amphidromic system lies in the southeast of the Gulf of Thailand and an S-2 amphidromic system at the near-shore area of the northeast South China Sea. The linear tidal energy equation developed by Garrett (1975 Deep-Sea Research 22, 23-35) is generalized to the nonlinear case. Based on the numerical results, the energy budgets in the South China Sea and its subareas, namely the Taiwan Strait, the Gulf of Tonkin, the Gulf of Thailand and the remaining area are investigated. The tidal motion in the Taiwan Strait is maintained mainly by the energy fluxes from the East China Sea for both semidiurnal and diurnal species and partially from the Luzon Strait for semidiurnal species. For the other parts of the South China Sea, the tidal motion is mainly maintained by the energy fluxes through the Luzon Strait. The energy inputs from the tide-generating force are negative for semidiurnal species and positive for diurnal species. (C) 1999 Elsevier Science Ltd. All rights reserved.

Selección de un aislado del nucleopoliedrovirus de Helicoverpa armigera (HearNPV) para su uso como base de un bioinsecticida

Helicoverpa armigera (Lepidoptera; Noctuidae), conocida como el taladro del tomate, es una especie polífaga y de amplia distribución, responsable de grandes pérdidas económicas en más de 60 cultivos a lo largo de las regiones tropicales y subtropicales del mundo. Estas plagas se controlan mayoritariamente con plaguicidas químicos, aunque existe un gran interés por desarrollar otros agentes de control biológico. Entre estos, se encuentra el nucleopoliedrovirus de Helicoverpa armigera (HearNPV, Baculoviridae), que por sus características de seguridad y eficacia, sería útil para impulsar los programas de gestión integrada de plagas que se fomentan desde la Directiva 2009/128/CEE. El objetivo de este trabajo fue realizar una caracterización bioquímica y biológica de varios aislados de HearNPV : un aislado silvestre español (Badajoz) HearNPV-SP1, un aislado chino HearSNPV-G4, tres aislados sudafricanos (HearNPV-Whl, HearNPV-Kzn, HearNPV-Alb) y la materia activa de un producto comercial en uso en Europa (HearNPV-Hx). El análisis con las enzimas de restricción determinó que la enzima BglII generaba perfiles similares pero con fragmentos característicos en todos los casos a excepción de los aislados HearNPV-Kzn y HearNPVAlb, que no pudieron ser diferenciados entre sí con ninguna de las enzimas probadas. El análisis filogenético, basado en las secuencias parciales de los genes poliedrina (polh), lef-8 y lef-9, donde se incluyeron las secuencias correspondientes a 18 genomas mostró que el aislado HearNPV-Whl es filogenéticamente próximo a las cepas de origen ibérico, mientras que los aislados HearNPV-Hx y HearNPV-Alb comparten la misma rama que los aislados asiáticos y australiano. La caracterización insecticida de los aislados HearNPV-SP1, HearNPV-Hx y HearNPV-G4 reveló que la virulencia (TMM) del aislado HearNPV-SP1 (104 h) fue significativamente menor que la de los aislados HearNPV-G4 (109 h) y HearNPV-Hx (111 h). En este trabajo, se determinó que el tiempo de acción del HearNPV-SP1 es menor al de otros bioinsecticidas en uso en Europa, por lo que se confirma la posibilidad de mejorar los productos activos en uno de los aspectos más sensibles de cara a su comercialización como es su tiempo de actuación.

Enlightenment and mission in early nineteenth century South Africa

In the early 19th century the London Missionary Society’s activities in South Africa were the subject of great scandal and a source of disrepute. The behaviour and attitudes of the first wave of LMS missionaries had challenged, and caused outrage, to both the political and moral norms of the colony. The radical attitudes and unconventional private lives of many of the early missionaries had also clearly shocked the Directors in Europe. In these controversies, and in the manner that the Society dealt with them, there can be read a contestation about not only the character, but also the purpose of mission activity. Was the Missionary task to work for political stability, to spread European values and help prepare a compliant and educated workforce? Or was it to save ‘lost souls’ and turn people away from idolatry and sin? Or, again, was it to fight for the oppressed, to liberate slaves and oppose tyranny? These debates were framed in complex and contradictory ways by a larger discussion that was informed by the new ideas and agendas that had emerged in the 18th century, commonly referred to as ‘The Enlightenment’. This paper traces the contours of an engagement between ‘Evangelical’ values and ‘Enlightenment’ principles through an exploration of the issues of the day such as: abolitionism, women’s rights, civilization and savagery.

Dispossessing bare life: Towards a theoretical framework for examining power relations through economic development at the 2010 FIFA World Cup in South Africa

In the past twenty years an increasing number of Global South nations have vied for the rights to host prestigious and expensive sport mega events. This trend requires significant reflection given the enormous economic costs of these events, which often produce little capital gain for the host nation (Whitson & Horne, 2006). Furthermore, sport mega events are often utilized for their symbolic capital (Belanger, 2009), which sometimes manifests through forcing people from their land for the sake of “beautification” (Davis, 2006). In this project, then, I asked how technologies of power were utilized by FIFA, corporate stakeholders, and the South African government to control people who were marginal to, or impeded the success of, the World Cup in Nelspruit, South Africa. This project consisted of two parts: the first involved constructing a theoretical framework for better understanding power as it operates through sport mega events in general. To this end I employed Marxian notions of the ordering of physical space, Foucauldian conceptions of sovereignty and governmentality, and Agamben’s (1998) state of exception to determine how particular bodies are constituted and controlled through sport mega events. In the second part, I applied this theoretical framework to the events in South Africa to better elucidate how people became displaced and killed because of the 2010 FIFA World Cup. I used South African popular news and documentaries as empirical evidence and conducted a discursive analysis of said news media. Through this coverage it became apparent that the mega event created the conditions in which new forms of rogue sovereign partnerships could arise through a historically and spatially contingent process of capitalism. The rogue sovereigns’ para-juridico-political orders, the discourses and practices of accumulation by dispossession as a tactic and effect of govermentality, and other historical non-capital subjectivities such as racial identity, all contributed to constituting Agamben’s state of exception in which people could be displaced, killed or left to die in the events surrounding the World Cup.

Talking about colds and flu: The lay diagnosis of two common illnesses among older British people

This paper reports on a study of the ways in which 54 older people in South Wales (UK) talk about the symptoms and causes of cold and influenza (flu). The study was designed to understand why older people might reject or accept the offer of seasonal flu vaccine, and in the course of the interviews respondents were also asked to express their views about the nature and causes of the two key illnesses. The latter are among the most common infections in human beings. In terms of the biomedical paradigm the common cold is caused by numerous respiratory viruses, whilst flu is caused by the influenza virus. Medical diagnosis is usually made on clinical grounds without laboratory confirmation. Symptoms of flu include sudden onset of fever and cough, and colds are characterized by sneezing, sore throat, and runny nose, but in practice the symptoms often overlap. In this study we examine the degree by which the views of lay people with respect to both diagnosis and epidemiology diverge with that which is evident in biomedical discourse. Our results indicate that whilst most of the identified symptoms are common to lay and professional people, the former integrate symptoms into a markedly different observational frame from the latter. And as far as causation is concerned it is clear that lay people emphasize the role of 'resistance' and 'immunity' at least as much as 'infection' in accounting for the onset of colds and flu. The data are analyzed using novel methods that focus on the co-occurrence of concepts and are displayed as semantic networks. As well as reporting on its findings the authors draw out some implications of the study for social scientific and policy discussions concerning lay diagnosis, lay expertise and the concept of an expert patient.
