Teve sua primeira edição publicada em Londres, em 1816. No ano seguinte, foi confeccionada uma segunda edição, que, em seguida, foi traduzida para o alemão e para o francês, esta sob o título Voyages dans la partie septentrionale du Brésil, depuis 1809 jusqu'en 1815..., em dois volumes. Muito bem recebida pela crítica, logo tornou-se um trabalho clássico sobre o Nordeste do Brasil.

A formação da Lagoa dos Patos foi condicionada pelo desenvolvimento de uma barreira múltipla, arenosa, sob a influência das oscilações eustáticas ocorridas durante o Quaternário. Os aspectos geomorfológicos da margem lagunar desta barreira evidenciam a existência de pelo menos quatro ciclos de transgressão e regressão. Os processos de sedimentação que os acompanharam, proporcionaram a compartimentação da laguna mediante o crescimento de pontais arenosos, mecanismo que deu origem a Lagoa - do Casamento e ao Saco do Cocuruto. Os sedimentos do fundo destes corpos lagunares são arenosos e silticos. As fácies arenosas ocorrem nas partes marginais e rasas e tem suas caracteristicas texturais influenciadas pelo tipo de material das áreas fonte, da natureza, intensidade e tempo de atuação dos agentes de sedimentação. As fácies silticas ocupam as porções centrais, mais profundas. As zonas intermediárias são atapetadas por fácies transicionais areno-silticas e silto-arenosas.Os terrenos quaternários da margem lagunar, retrabalhados durante os ciclos transgressivos, constituem a principal fonte dos sedimentos lagunares. Parte do material siltico trazido em suspensão pelas águas da Lagoa dos Patos que ingressam na Lagoa do Casamento, provém das terras altas que margeiam a provincia Costeira. Os principais agentes envolvidos nos processos de sedimentação são o vento, as ondas e as correntes lagunares. A circulação das águas é também influenciada pelos sistemas fluviais atuantes na região. A sedimentação se processa em um ambiente de águas rasas e doces, levemente ácidas, oxidantes nas margens e pouco redutoras nas partes centrais. A atividade biológica bentônica é reduzida e relacionada a uma pequena fauna de moluscos. A evolução geomorfológica da área controlou os aspectos maiores da sedimentação no corpo lagunar. Tentativas de caracterização ambiental baseadas em análise granulométrica mostraram que os métodos de FOLK & WARD (1957), PASSEGA & BYRANJEE (1969) e DOEGLAS (1968),são efetivamente úteis na descrição e interpretação de ambientes recentes de sedimentação onde os parâmetros físicos são conhecidos. Entretanto a sua utilização como critério único na determinação paleo-ambiental fica prejudicada, pois a sedimentação em uma província costeira e policíclica e promovida por vários ambientes definidos que se deslocam no tempo e no espaço. Ocorre muitas vêzes que o rápido retrabalhamento de materiais depositados em ambientes de alta energia é incapaz de apagar as características texturais herdadas do ciclo anterior A maior parte dos sedimentos das fácies arenosas do fundo lagunar tem propriedades semelhantes aos depositados em ambientes praiais e eólicos.

This study had a multidisciplinary focus, investigating the areas of health and education, and proposes to discuss the formation of health professionals, requiring their understanding of the factors involved in the production of knowledge, given that this formation has an impact on the quality of human and social life. The aim of this work was to investigate the relationship existing between the process of physical therapist formation and the practical activities developed during the undergraduate course in the Northeast of Brazil. This is an exploratory descriptive study with qualitative significance. The sample consisted of 73 subjects (33 professors and 40 students) from 6 physical therapy courses at different institutions in the Northeast of Brazil. Data collection was conducted through focus group interviews. In addition, we used a school assessment instrument from the health area. The data, analyzed using dialectical hermeneutics, showed that the Northeast of Brazil has the second largest number of physical therapy courses in the country, with 93 (11 public and 82 private) out of a total of 510. These numbers represent a growth of 1062.5% since 1991. The pedagogical projects are guided by National Curricular Directives as well as by the country s health system. The prevalent pedagogy is that of transmission, and the contents/disciplines are generally not integrated with practice, a situation that hinders the integrality and interdisciplinarity of health care. It can be concluded that there is a need for implementing integrated curricula and for better qualified professors to effectively put this process into practice

One of the greatest challenges of demography, nowadays, is to obtain estimates of mortality, in a consistent manner, mainly in small areas. The lack of this information, hinders public health actions and leads to impairment of quality of classification of deaths, generating concern on the part of demographers and epidemiologists in obtaining reliable statistics of mortality in the country. In this context, the objective of this work is to obtain estimates of deaths adjustment factors for correction of adult mortality, by States, meso-regions and age groups in the northeastern region, in 2010. The proposal is based on two lines of observation: a demographic one and a statistical one, considering also two areas of coverage in the States of the Northeast region, the meso-regions, as larger areas and counties, as small areas. The methodological principle is to use the General Equation and Balancing demographic method or General Growth Balance to correct the observed deaths, in larger areas (meso-regions) of the states, since they are less prone to breakage of methodological assumptions. In the sequence, it will be applied the statistical empirical Bayesian estimator method, considering as sum of deaths in the meso-regions, the death value corrected by the demographic method, and as reference of observation of smaller area, the observed deaths in small areas (counties). As results of this combination, a smoothing effect on the degree of coverage of deaths is obtained, due to the association with the empirical Bayesian Estimator, and the possibility of evaluating the degree of coverage of deaths by age groups at counties, meso-regions and states levels, with the advantage of estimete adjustment factors, according to the desired level of aggregation. The results grouped by State, point to a significant improvement of the degree of coverage of deaths, according to the combination of the methods with values above 80%. Alagoas (0.88), Bahia (0.90), Ceará (0.90), Maranhão (0.84), Paraíba (0.88), Pernambuco (0.93), Piauí (0.85), Rio Grande do Norte (0.89) and Sergipe (0.92). Advances in the control of the registry information in the health system, linked to improvements in socioeconomic conditions and urbanization of the counties, in the last decade, provided a better quality of information registry of deaths in small areas

Modem production systems accommodate broody hens in high densities, leading to the accumulation of excrement under the cages. This substrate is excellent for the development of sinantropic flies. Thus, the accomplishment of surveys in these places becomes essential, in order to plan better strategies of control. The present work aimed at studying the entornofauna and the seasonality of the species of dipterous present in the Crisdan poultry house located in the Municipality of Sao Joao da Boa Vista, the State of São Paulo, Brazil. In the period of January of 2001 to December of 2002, 1,012,595 flies were captured using the "jug-trap". The species were identified: Drosophi-la repleta (Wollaston, 1858), Musca domestica (Linnaeus, 1758), Ophyra spp., Hennetria illucens (Linnaeus, 1758), Fannia canicularis (Linnaeus, 1761), Chrysomya megacephala (Fabricius, 1794), and Sepsidae. More frequently D. repleta and M. domestica had added 99.47% of the dipterous. Increased rainfall and the collection months influenced the sampling of dipterous (P < 0.05). Drosophila repleta was the most abundant species, representing 91% of all captured flies. However, this diptera did not develop at the surveyed site since immatures were not captured therein.

Brazil is one of the major centers of diversity for polyploid cotton plants; these plants belong to the genus Gossypium, which has three known species: G. hirsutum, G. barbadense and G. mustelinum. The Northeast is the only region where the three species occur, the last group being endemic. Northeast s cotton plants can be important sources of variability for genetic breeding. It is believed that great part of local diversity is being lost, due to economic, political, cultural and agricultural problems. In an attempt to mitigate this loss and delineate conservation strategies it is necessary to know how the species are found where they occur. The objective was to characterize and determine how plants are maintained in situ in the states of Maranhão, Piauí, Ceará, Rio Grande do Norte and Paraíba at the beginning of the XXI century. The in situ characterization of G. hirsutum and G. barbadense was conducted through structured interviews with the cotton plants owners and through the analysis of the environment. The data were collected during expeditions undertaken between the years 2004 to 2005. Twenty-two plants were collected in the state of Paraíba, forty-four in the state of Rio Grande do Norte, one hundred and forty-six in the state of Ceará, forty in the state of Maranhão and ninety-one plants in the state of Piauí. All plants collected in the states of Paraíba and Rio Grande do Norte belonged to moco type. Moco cotton plants also predominated in the other states, representing 92%, 62% and 78% of plants collected in Ceará, Piauí and Maranhão, respectively. The other cotton plants collected belong to the species G. barbadense. The cotton plants were found in situ as dooryard plants, roads side, feral populations, cultivation or local varieties. Great part were dooryard plants (45.2%), being major in Piauí and Maranhão. Cultivation predominated in Ceará; in Rio Grande do Norte feral populations were the most frequent and, in Paraíba, local varieties. The maintenance of moco plants is related, mainly, to the phytotherapic domestic use (20.9%) and to confection of lamp wicks (29.7%). Few inhabitants in Paraíba, Rio Grande do Norte, Piauí and none in Maranhão used harvest the plants, storage the seeds or gin; however, in Ceará, 40.5% of owners affirmed that they harvested and commercialized the fiber. It was found that the maintenance of species is dependent of the fragile cultural habits of local inhabitants, therefore the maintenance in situ is not a suitable way to conservation of genetic resources. The efforts must be directed to the continuity of collections, maintenance and characterization ex situ

The acoustic ecology concept involve the relation between the live organisms and their sound environment and is applied in the present work to study the context in which the humpback whale (Megaptera novaeangliae) singing behavior, known as the most complex display in the nature, occurred in the northeastern Brazilian coast, outside the core area of Abrolhos Bank, between 2005 and 2010.I analyze the singer male occurrence , their spatial distribution and probable relations with oceanographic features, such as depth, tide regimen and moon phases. I also describe the acoustic structure and temporal variation of the singing behavior, based on song frequency and time measurements outside the Abrolhos Bank, and further compare the song complexity, registered in the same period, between Abrolhos Bank (16°- 19° S, 37°- 39° W) and the adjacent North Coast, herein considered from Itacaré (14° S, 38° W) to Aracaju (11° S, 37° W). Additionally, I look for describe and analyze anthropogenic noise sources in the marine environment of the study area, produced by the oil industry as well as by the whale watching operation, relating their frequencies to the acoustic niche utilized by the humpbacks. The results indicated a great plasticity in the singing behavior, evidenced by the occurrence of singer males in diverse social structures, from solitary individuals to other groups, even containing females and calves, as well as by the diversity which compound the song, when compared between two regions inside the same breeding area, which present distinct oceanographic characteristics. The singer male distribution may be related with the continental shelf extent along the study area. The anthropogenic noise presented frequency range, amplitude and sound intensity in potential to interfere acoustically in the singing behavior of the species, may resulting in disturbance during the breeding season in the Brazilian coast. Implications about the obtained results in the humpback whale mating system are discussed. In this way, I pretend to contribute with the acoustic ecology subject and provide information to subsidize humpback whale conservation

No presente trabalho foram estudados os ácaros associados a plantas ornamentais de praças, ruas e jardins residenciais, no município de Ilha Solteira, SP. Foram amostradas folhas de 20 espécies de plantas e alguns representantes das morfoespécies de ácaros encontrados foram montados em lâminas de microscopia com o meio de Hoyer, para posterior identificação sob microscópio óptico com contraste de fases. Foram registradas 23 espécies pertencentes a 15 gêneros de oito famílias. Dessas espécies, 13 são fitófagas, nove predadoras e uma de hábito alimentar não determinado. A família com maior riqueza de ácaros foi Tetranychidae, com nove espécies, sendo uma delas registrada pela primeira vez após a descrição original e outra pela primeira vez no Brasil. Lorryia formosa Cooremann, 1958 (Tydeidae) foi a que ocorreu em maior número de hospedeiros. As plantas com as maiores riquezas de ácaros foram Lagerstroemia indica L., Mussaenda alicia Hort. e Tabebuia sp., com seis espécies registradas em cada uma.

Programas que visam o controle biológico precisam ser embasados principalmente em liberações de predadores e parasitóides para tentar minimizar efeitos adversos para o ambiente. Os coleópteros da família Histeridae como predam larvas de dípteros sinantrópicos podem auxiliar no controle das moscas que se desenvolvem em fezes acumuladas. Este trabalho teve como objetivo realizar um levantamento das espécies de histerídeos em granja avícola no município de São João da Boa Vista, estado de São Paulo, verificar seu padrão sazonal de ocorrência e investigar possíveis associações entre as mesmas. As coletas foram realizadas de janeiro de 2001 a dezembro de 2002, utilizando-se dois métodos de coleta (armadilhas de solo e o funil de Berlese - Tullgren). As espécies de histerídeos encontradas foram: Euspilostus modestus, Euspilostus (Hesperosaprinus) spp., Carcinops troglodytes e Hololepta quadridentata. O número de cada espécie diferiu entre os métodos utilizados. Na armadilha de solo, E. modestus correspondeu a 87,01% do número total de indivíduos capturados, enquanto que no funil, C. troglodytes obteve maior destaque (84,38%). E. modestus e H. quadridentata apresentaram padrões de variação mensal positivamente correlacionada com a precipitação pluviométrica (P<0,05 e P<0,01, respectivamente).
