Codigo Brasiliense, ou, Collecção das leis, alvarás, decretos, cartas regias &c., promulgadas no Brasil desde a feliz chegada do Principe Regente N. S. a estes Estados

O Codigo Brasiliense reúne as primeiras leis promulgadas em solo brasileiro, desde o ano de 1808 até 1822, abrangendo todo o Período Joanino. Essas leis fazem parte dos primeiros impressos produzidos pela Impressão Regia, possuindo, portanto, a característica de incunábulos brasileiros. Segundo pesquisa da John Carter Brown Library, existem várias versões tipograficamente diferentes, não encadernadas, impressas possivelmente em Lisboa. As diferenças podem ser detectadas, particularmente, pela capital ornamentada E, cuja variante digitalizada encontra-se no site daquela instituição. É muito raro encontrar em um mesmo acervo os 3 volumes que compõem o Código e, mais ainda, encontrar exemplares completos. É obra importantíssima para a memória brasileira.

Accelerating loss of seagrasses across the globe threatens coastal ecosystems

Coastal ecosystems and the services they provide are adversely affected by a wide variety of human activities. In particular, seagrass meadows are negatively affected by impacts accruing from the billion or more people who live within 50 km of them. Seagrass meadows provide important ecosystem services, including an estimated $1.9 trillion per year in the form of nutrient cycling; an order of magnitude enhancement of coral reef fish productivity; a habitat for thousands of fish, bird, and invertebrate species; and a major food source for endangered dugong, manatee, and green turtle. Although individual impacts from coastal development, degraded water quality, and climate change have been documented, there has been no quantitative global assessment of seagrass loss until now. Our comprehensive global assessment of 215 studies found that seagrasses have been disappearing at a rate of 110 square kilometers per year since 1980 and that 29% of the known areal extent has disappeared since seagrass areas were initially recorded in 1879. Furthermore, rates of decline have accelerated from a median of 0.9% per year before 1940 to 7% per year since 1990. Seagrass loss rates are comparable to those reported for mangroves, coral reefs, and tropical rainforests and place seagrass meadows among the most threatened ecosystems on earth.

NOAA Coastal Change Analysis Program (C-CAP): Guidance for Regional Implementation

EXECUTIVE SUMMARY: The Coastal Change Analysis Programl (C-CAP) is developing a nationally standardized database on landcover and habitat change in the coastal regions of the United States. C-CAP is part of the Estuarine Habitat Program (EHP) of NOAA's Coastal Ocean Program (COP). C-CAP inventories coastal submersed habitats, wetland habitats, and adjacent uplands and monitors changes in these habitats on a one- to five-year cycle. This type of information and frequency of detection are required to improve scientific understanding of the linkages of coastal and submersed wetland habitats with adjacent uplands and with the distribution, abundance, and health of living marine resources. The monitoring cycle will vary according to the rate and magnitude of change in each geographic region. Satellite imagery (primarily Landsat Thematic Mapper), aerial photography, and field data are interpreted, classified, analyzed, and integrated with other digital data in a geographic information system (GIS). The resulting landcover change databases are disseminated in digital form for use by anyone wishing to conduct geographic analysis in the completed regions. C-CAP spatial information on coastal change will be input to EHP conceptual and predictive models to support coastal resource policy planning and analysis. CCAP products will include 1) spatially registered digital databases and images, 2) tabular summaries by state, county, and hydrologic unit, and 3) documentation. Aggregations to larger areas (representing habitats, wildlife refuges, or management districts) will be provided on a case-by-case basis. Ongoing C-CAP research will continue to explore techniques for remote determination of biomass, productivity, and functional status of wetlands and will evaluate new technologies (e.g. remote sensor systems, global positioning systems, image processing algorithms) as they become available. Selected hardcopy land-cover change maps will be produced at local (1:24,000) to regional scales (1:500,000) for distribution. Digital land-cover change data will be provided to users for the cost of reproduction. Much of the guidance contained in this document was developed through a series of professional workshops and interagency meetings that focused on a) coastal wetlands and uplands; b) coastal submersed habitat including aquatic beds; c) user needs; d) regional issues; e) classification schemes; f) change detection techniques; and g) data quality. Invited participants included technical and regional experts and representatives of key State and Federal organizations. Coastal habitat managers and researchers were given an opportunity for review and comment. This document summarizes C-CAP protocols and procedures that are to be used by scientists throughout the United States to develop consistent and reliable coastal change information for input to the C-CAP nationwide database. It also provides useful guidelines for contributors working on related projects. It is considered a working document subject to periodic review and revision.(PDF file contains 104 pages.)

Documentos officiaes relativos à negociação do tractado entre Portugal e a Gram Bretanha para a supressão do trafico da escravatura : mandados imprimir por ordem da Camara dos Senadores

O Parlamento Britânico adotou, em 1840, uma lei proposta por Lord Palmerston, autorizando os navios de guerra britânica a "capturar, em todos os mares as embarcações que, com bandeira portuguesa, se empreguem ou sejam suspeitas de empregar-se no tráfico da escravatura". O Visconde de Sá Bandeira, que havia negociado com o governo inglês vários acordos e projetos de tratados, escreveu um livro sobre o assunto, onde há informações históricas importantes não só a respeito da escravidão nas colônias portuguesas como nas inglesas, nas dinamarquesas, francesas, espanholas e nos Estados Unidos. O presente exemplar é autografado pelo autor.

Factos do espirito humano : philosophia

Domingos José Gonçalves de Magalhães, Visconde de Araguaia, nasceu no Rio de Janeiro, em 13 de agosto de 1811, e morreu em Roma, em 1822, onde, então, exercia função diplomática. Formou-se em Medicina, mas deu preferência à atividade literária e à carreira diplomática.Foi também eleito deputado à Assembleia Geral Legislativa. Seu primeiro livro, Poesias, foi publicado em 1832. Fundou a Niterói : Revista Brasiliense, com o propósito de promover a reforma romântica de nossas letras. Foi aí que publicou o Ensaio sobre a história da literatura no Brasil : discurso preliminar, verdadeiro manifesto de reforma romântica, e, ao mesmo tempo, lançou o livro de poesias Suspiros poéticos e saudades, que toda a crítica da época apontou como obra iniciadora do Romantismo no Brasil. Suas obras completas - literárias, históricas e filosóficas -, em oito tomos, foram lançadas pela Garnier, de 1864 a 1876.

圆偏振光和线偏振光在正常色散材料中的时空自压缩

实验研究了圆偏振和线偏振高强度飞秒激光脉冲在正常色散材料中传输时的时空自压缩现象。实验中利用BK7玻璃作为正色散材料，比较研究了不同偏振入射情况下脉冲波形及频谱的变化规律。圆偏振光入射时，可以获得更短脉冲宽度的压缩脉冲和更窄的光谱宽度。在圆偏振光入射条件下，50fs入射脉冲成功地自压缩到了19fs，获得了大于2．5倍的压缩倍率。所以利用圆偏振光可以获得更短压缩脉冲，更大能量，更好光束质量的激光。

A search for fractionally charged particles in cosmic rays and a theoretical interpretation of the results

An array of two spark chambers and six trays of plastic scintillation counters was used to search for unaccompanied fractionally charged particles in cosmic rays near sea level. No acceptable events were found with energy losses by ionization between 0.04 and 0.7 that of unit-charged minimum-ionizing particles. New 90%-confidence upper limits were thereby established for the fluxes of fractionally charged particles in cosmic rays, namely, (1.04 ± 0.07)x10^-10 and (2.03 ± 0.16)x10^-10 cm^-2sr^-1sec^-1 for minimum-ionizing particles with charges 1/3 and 2/3, respectively.

In order to be certain that the spark chambers could have functioned for the low levels of ionization expected from particles with small fractional charges, tests were conducted to estimate the efficiency of the chambers as they had been used in this experiment. These tests showed that the spark-chamber system with the track-selection criteria used might have been over 99% efficient for the entire range of energy losses considered.

Lower limits were then obtained for the mass of a quark by considering the above flux limits and a particular model for the production of quarks in cosmic rays. In this model, which is one involving the multi-peripheral Regge hypothesis, the production cross section and a corresponding mass limit are critically dependent on the Regge trajectory assigned to a quark. If quarks are "elementary'' with a flat trajectory, the mass of a quark can be expected to be at least 6 ± 2 BeV/c². If quarks have a trajectory with unit slope, just as the existing hadrons do, the mass of a quark might be as small as 1.3 ± 0.2 BeV/c². For a trajectory with unit slope and a mass larger than a couple of BeV/c², the production cross section may be so low that quarks might never be observed in nature.

发射和接收光束同时开关的激光测距法

采用同一电光器件对发射和接收光束同时开关的原理，提出了一种新颖的激光测距方法。光源发出的连续激光被待测目标反射后，往返两次通过光源端的电光晶体，在晶体上施加边沿急速变化的电压，利用其高速响应的开关特性，同时对往返光线产生影响，截取出一段包含激光往返待测距离所需时间信息的光强变化曲线。实验中利用雪崩管电路实现了纳秒级的高压上升沿，并利用单轴晶体的双折射和全内双反射性质，用特殊结构的单块LiNbO3晶体实现了该方法的测距装置。示波器分析的实验结果验证了该方法的可行性，从而为激光测距开拓了一种新的思路。

Of angels and demons: Virginia Woolfs homicidal legacy in Sylvia Plaths: The bell jar.

Esta dissertação é um estudo comparativo do legado vitoriano deixado para as escritoras do século XX, Virginia Woolf e Sylvia Plath. Primeiro discutem-se as agências controladoras do corpo feminino na era vitoriana e a formação de um ideal de feminilidade que chamamos de Anjo do Lar. Em seguida, discute-se como Virginia Woolf apreende essa imagem e a subverte, criando seu duplo, que chamamos de Demônio do Lar. Por fim, promovemos o diálogo entre Sylvia Plath e Virginia Woolf. Plath parece escrever aos moldes de Woolf, criando uma literatura de morte, feita para assassinar o Anjo do Lar. Usamos para tal estudo o conceito de écriture féminine, criado pelas francófonas Hélène Cixous, Luce Irigaray, e Julia Kristeva, entre outras, para traçar os paralelos entre um lugar para o feminino na escrita e a busca de uma tradição por Woolf. A abjeção de Kristeva, a dinâmica de poder entre alma e corpo de Foucault e o conceito de duplo de Otto Rank nos ajudarão, por fim, a entender como se dá a morte do Anjo na literatura, especificamente no romance A redoma de vidro (1963) de Sylvia Plath
