Na Europa Central, onde ocorreram as principais batalhas terrestres, chamou-se Guerra dos Sete Anos; na Inglaterra, que foi a principal vencedora, chamou-se A Grande Guerra do Império; Nos Estados Unidos e no Canadá, que passou a ser inglês ao final dos combates, chamou-se de Guerra Franco-Índia.

The Tanzania Coastal Management Partnership (TCMP) works to implement the National Integrated Coastal Environmental Management Strategy (ICEMS) in Tanzania’s coastal landscapes and seascapes, funded in large measure by the U.S. Agency for International Development. The overarching goal of the Sustainable Coastal Communities and Ecosystems in Tanzania (SUCCESS Tanzania) initiative is to conserve coastal and marine biodiversity while improving the well being of coastal residents through implementation of the Tanzania ICEMS and related ICM policies and strategies. It does this by focusing on three key results: -Policies and Laws that Integrate Conservation and Development Applied -Participatory Landscape Scale Conservation Practiced -Conservation Enterprises Generate Increased and Equitable Benefits from Sustainable Use An additional result sought in the program is gender equity and HIV/AIDS preventive behaviors promoted through communicating HIV/AIDS, environment, and equity messages.

The structure of the inhibition patterns is important to the stimulated emission depletion (STED) microscopy. Usually, Laguerre-Gaussian (LG) beam and the central zero-intensity patterns created by inserting phase masks in Gaussian beams are used as the erase beam in STED microscopy. Aberration is generated when focusing beams through an interface between the media of the mismatched refractive indices. By use of the vectorial integral, the effects of such aberration on the shape of depletion patterns and the size of fluorescence emission spot in the STED microscopy are studied. Results are presented as a comparison between the aberration-free case and the aberrated cases. (C) 2009 Optical Society of America

在用大口径、长焦距平行光管模拟激光远场特性时,其光组透镜在重力作用下的变形不能忽略,为了分析对出射光束质量的影响,采用有限元分析软件“ANSYS”建立了平行光管光组中声400mm平凸透镜的有限元模型,给出一种分析透镜轴向变形引起的波像差的方法,在不同工况下,计算了平凸透镜在重力作用下轴向变形的峰谷值和均方根值,对轴向变形量均方根值最小工况画出了透镜表面变形的等值线图,计算了声350mm通光口径内的波像差峰谷值和均方根值,对平行光管光组的波像差做出估计,验证了设计的合理性。

This paper investigates the influences of phase shift on superresolution performances of annular filters. Firstly, it investigates the influence of phase shift on axial superresolution. It proves theoretically that axial superresolution can not be obtained by two-zone phase filter with phase shift pi, and it gets the phase shift with which axial superresolution can be brought by two-zone phase filter. Secondly, it studies the influence of phase shift on transverse superresolution. It finds that the three-zone phase filter with arbitrary phase shift has an almost equal optimal transverse gain to that of commonly used three-zone phase filter, but can produce a much higher axial superresolution gain. Thirdly, it investigates the influence of phase shift on three-dimensional superresolution. Three-dimensional superresolution capability and design margin of three-zone complex filter with arbitrary phase shift are obtained, which presents the theoretical basis for three-dimensional superresolution design. Finally, it investigates the influence of phase shift on focal shift. To obtain desired focal shifts, it designs a series of three-zone phase filters with different phase shifts. A spatial light modulator (SLM) is used to implement the designed filters. By regulating the voltage imposed on the SLM, an accurate focal shift control is obtained.

O presente trabalho tem por objetivo investigar a relação do pensamento de Michel Foucault com o de Immanuel Kant a partir das perspectivas encontradas em dois momentos específicos de suas obras em que localiza o pensador alemão no limiar de nossa modernidade: em As palavras e as coisas (1966) e nos textos tardios (1978 a 1984) que versam sobre a resposta dada por Kant à pergunta Was ist Aufklärung?, de 1784. Na primeira parte, analisamos tal perspectiva a partir da distinção kantiana entre o empírico e o transcendental em sua relação com a problematização do sono antropológico". Para tal, centramo-nos nos primeiros escritos de Foucault, tomando como pontos de ancoragem a Tese Complementar (1961) e As palavras e as coisas (1966). Na segunda parte, ela é abordada a partir da questão da Aufklärung em sua relação com a noção de governo, examinando a maneira pela qual Foucault vincula seu trabalho à tradição crítica de uma ontologia do presente que teria sido instaurada pelo pensador alemão. O resultado obtido através do entrecruzamento destas duas perspectivas permite reconhecer que o pensamento de Kant ocupa, para Foucault, um lugar de singularidade na história da filosofia, caracterizado pela reativação permanente de uma atitude que é em si mesma um êthos filosófico, isto é, uma crítica permanente de nosso ser histórico.

A total of 1784 legal-size (≥356 mm TL) hatchery-produced red drum (Sciaenops ocellatus) were tagged and released to estimate tag-reporting levels of recreational anglers in South Carolina (SC) and Georgia (GA). Twelve groups of legal-size fish (~150 fish/group) were released. Half of the fish of each group were tagged with an external tag with the message “reward” and the other half of the fish were implanted with tags with the message “$100 reward.” These fish were released into two estuaries in each state (n=4); three replicate groups were released at different sites within each estuary (n=12). From results obtained in previous tag return experiments conducted by wildlife and fisheries biologists, it was hypothesized that reporting would be maximized at a reward level of $100/tag. Reporting level for the “reward” tags was estimated by dividing the number of “reward” tags returned by the number of “$100 reward” tags returned. The cumulative return level for both tag messages was 22.7 (±1.9)% in SC and 25.8 (±4.1)% in GA. These return levels were typical of those recorded by other red drum tagging programs in the region. Return data were partitioned according to verbal survey information obtained from anglers who reported tagged fish. Based on this partitioned data set, 14.3 (±2.1)% of “reward” tags were returned in SC, and 25.5 (±2.3)% of “$100 reward” tags were returned. This finding indicates that only 56.7% of the fish captured with “reward” tags were reported in SC. The pattern was similar for GA where 19.1 (±10.6)% of “reward” message tags were returned as compared with 30.1 (±15.6)% for “$100 reward” message tags. This difference yielded a reporting level of 63% for “reward” tags in GA. Currently, 50% is used as the estimate for the angler reporting level in population models for red drum and a number of other coastal finfish species in the South Atlantic region of the United States. Based on results of our study, the commonly used reporting estimate may result in an overestimate of angler exploitation for red drum.
