Poema do Mar dá voz ao ideal da ―terra-longe‖ e ao ―querer bipartido‖1 do poeta caboverdiano mais desencantado frente à terra-cretcheu, amada. Jorge Barbosa (1902-1971) foi, juntamente com Baltasar Lopes e Manuel Lopes, uma das figuras de proa da Claridade. O aparecimento desta revista, em 1936, define o moderno movimento cultural caboverdiano. Conscientes da sua unidade cultural, pretendiam os ―claridosos‖ romper em definitivo com a subalternidade que os cingia à temática europeia, libertando o acto criador de tão colonial alienação. Já em 1935, ao publicar o seu primeiro livro, Arquipélago, Jorge Barbosa vencera a tradicional dependência dos modelos metropolitanos e tornava-se pioneiro da moderna poesia caboverdiana.

No trabalho realizado nesta tese, procedeu-se ao estudo hidrodinâmico de uma
coluna de borbulhamento de recirculação externa do líquido (CREL), que permitiu ampliar o
conhecimento já existente sobre este tipo de colunas. Para realizar este estudo utilizaram-se
líquidos viscosos Newtonianos, nomeadamente soluções aquosas de glicerina com
viscosidades entre 0,007 e 0,522 Pa.s. Para a gama de caudais de ar injectados, 1,5x10-5
até 1,35x10-4 m3/s, o ar ascendia ao longo da coluna de borbulhamento sob a forma de
bolhas tubulares. Após a realização dos ensaios, verificou-se que o regime de escoamento
do líquido entre bolhas tubulares variou desde o tipo laminar até transição (1,9

During February of 1974, the western extremity of St. Jorge's Island, one of the Azores Islands group, was severely affected by intense earthquakes, causing heavy damage. One of the authors of the present work (T. P. R.) who at the time was employed in the Rosais Lighthouse, registered day after day all the phenomena he could observe, writting down a journal that is published herein. An introduction on the geology, tectonic's, and the seismology of St. Jorge’s Island, is presented. As it can be verified, this seismic crisis was associated to a short submarine vulcanic eruption.

We present a palaeomagnetic study on 38 lava flows and 20 dykes encompassing the past 1.3 Myr on S. Jorge Island (Azores ArchipelagoNorth Atlantic Ocean). The sections sampled in the southeastern and central/western parts of the island record reversed and normal polarities, respectively. They indicate a mean palaeomagnetic pole (81.3 degrees N, 160.7 degrees E, K= 33 and A95= 3.4 degrees) with a latitude shallower than that expected from Geocentric Axial Dipole assumption, suggesting an effect of non-dipolar components of the Earth magnetic field. Virtual Geomagnetic Poles of eight flows and two dykes closely follow the contemporaneous records of the Cobb Mountain Subchron (ODP/DSDP programs) and constrain the age transition from reversed to normal polarity at ca. 1.207 +/- 0.017 Ma. Volcano flank instabilities, probably related to dyke emplacement along an NNWSSE direction, led to southwestward tilting of the lava pile towards the sea. Two spatially and temporally distinct dyke systems have been recognized on the island. The eastern is dominated by NNWSSE trending dykes emplaced before the end of the Matuyama Chron, whereas in the central/western parts the eruptive fissures oriented WNWESE controlled the westward growth of the S. Jorge Island during the Brunhes Chron. Both directions are consistent with the present-day regional stress conditions deduced from plate kinematics and tectonomorphology and suggest the emplacement of dykes along pre-existing fractures. The distinct timing and location of each dyke system likely results from a slight shift of the magmatic source.

Sixty-four isogenic Swiss mice were intradermically inoculated in both hind foot pads. The inocula, consisting of fungal suspensions from biopsies obtained from Jorge Lobos Disease patients, had the total number of fungi and the viability index determined using a Neubauer chamber and the fluorescein diacetate-ethidium bromide technique (FD-EB), respectively. The animals were sacrificed at times ranging from ten days to eighteen months after inoculation. The cellular infiltrate, mainly consisting of macrophages containing fungi, increased progressively up to end of the study; however, no macroscopic alterations were observed in the inoculated feet. After nine months, small numbers of Langhans giant cells started to appear in the infiltrate. A considerable number of fungi was observed at the end of the experimental period, but only a few were viable when stained by the FD-EB technique. This fact suggests that there is a multiplication of fungal cells, which are destroyed by the macrophages but remain in the tissue for a long time due perhaps to the difficulties in their elimination. These findings led us to conclude that in spite of the maintenance of the infection in these animals, Swiss mice cannot be considered an ideal model to study Jorge Lobos Disease. However, the authors call attention to the possibility of other mouse strains being more susceptible to Paracoccidioides loboi.

Este trabalho trata do tema do controlo de gestão. Após uma introdução e discussão do conceito, são apresentados alguns dos mais relevantes modelos de controlo de gestão, nomeadamente, a contabilidade de gestão, o controlo orçamental, a qualidade total, a teoria das limitações e o balanced scorecard. Posteriormente, é apresentado um estudo realizado numa empresa têxtil‐lar, analisando‐se o caso da empresa Portuguesa Têxteis Tarf, Lda. Neste contexto, procura‐se testar um modelo que permita fazer a selecção das encomendas de clientes de forma a maximizar a rentabilidade da empresa. Para o efeito, recorreu‐se aos conceitos propostos pela Teoria das Limitações. Os resultados do estudo apontam no sentido de a máxima rentabilidade da empresa ser função da limitação que for identificada para cada conjunto de encomendas temporalmente simultâneas. Assim, no caso concreto, consoante as encomendas de diferentes produtos (têxteis lar) e de diferentes quantidades encomendadas de cada produto, as opções de gamas de produção serão diferentes e determinadas pelas margens operativas por minuto da limitação.

The objective of the present study was to evaluate the serum viral load in chronically infected Hepatitis B virus (HBV) patients and to investigate the distribution of HBV genotypes in São Paulo city. Quantitative HBV-DNA assays and HBV genotyping have gained importance for predicting HBV disease progression, have been employed for assessing infectivity, for treatment monitoring and for detecting the emergence of drug resistance. Twenty-nine Brazilian patients with suspected chronic hepatitis B were studied, using real time PCR for viral load determination and direct DNA sequencing for the genotyping. The serology revealed chronic HBV infection in 22 samples. The HBV-DNA was positive in 68% samples (15/22). The phylogenetic analysis disclosed that eleven patients were infected with HBV genotype A, two with genotype F and two with genotype D. Thus, the genotype A was the most prevalent in our study.

Jorge Lobo's disease is a cutaneous and subcutaneous mycosis that affects patients in the Amazon region. The number of patients is relatively small, but the real situation of the disease as public health problem is not known, because Jorge Lobo's disease is not a notifiable disease. This study aims to report the clinical evolution in patients affected and to determine the prevalence and areas of occurrence of the disease. A retrospective study was carried out based on the analysis of the clinical records, which included a collection of photographs of patients in the Department of Sanitary Dermatology, in Rio Branco, and patients seen in the interior of the state. In a decade, in Rio Branco, 249 cases of the disease were reported, 30 were females and 219 males. Of these patients, 153 had localized lesions, 94 of them were on one ear, 55 had multifocal lesions and 41 had disseminated lesions. The average time between the onset of symptoms and diagnosis was 19 years. The average age at the time of diagnosis was 53 years, and ages ranged from 14 to 96 years.
