This study presents the first archeointensity results from Northeast Brazil obtained from 14 groups of architectural brick fragments sampled in the city of Salvador, Bahia State (13 degrees S, 38.5 degrees W) and dated between the middle of the XVIth century and the beginning of the XIXth century. The dating is ascertained by historical documents complemented by archeological constraints, yielding in all cases age uncertainties of less than 50 years. Analyses were carried out using two experimental protocols: 1 the ""zero field-in field"" version of the classical Thellier and Thellier method as proposed by Coe (TT-ZI), including partial thermoremanent magnetization (pTRM) and pTRM-tail checks, and 2 the Triaxe procedure involving continuous high temperature magnetization measurements. Both TRM anisotropy and cooling rate effects were taken into account for the intensity determinations. The cooling rate effect was further explored for the TT-ZI protocol using three increasing slow cooling times (5 h, 10 h and 25 h) between 450 C and room temperature. Following archeological constraints, the slowest cooling time was retained in our study, yielding decreases of the raw intensity values by 4% to 14%. For each fragment, a mean intensity was computed and retained only when the data obtained from all specimens (between 2 and 6) satisfied a coherence test at similar to 5%. A total of 57 fragments (183 specimens) was considered for the computations of site-mean intensity values...

O propósito deste estudo foi verificar a contribuição dos Distúrbios Ondulatórios de Leste (DOLs) na precipitação observada no período chuvoso (AMJJ) e avaliar previsões sazonais de chuva obtidas do RegCM3 (Regional Climate Model version 3) no Leste do Nordeste do Brasil (LNB). Para a identificação subjetiva dos DOLs foram utilizadas imagens de satélite no infravermelho e os campos de linhas de corrente e vorticidade relativa em 700 e 850 hPa da reanálise ERA-Interim, nos períodos chuvosos de 2006 a 2010. Cerca de 90% dos cavados observados em 700 hPa estiveram associados aos 116 DOLs que atingiram o LNB. Isto fornece média de 23 DOLs por ano com pequena variabilidade interanual. Foram construídas composições de variáveis meteorológicas desde 2 dias antes (-2) até 2 dias depois (+2) dos DOLs atingirem o LNB. A circulação apresentou anomalia ciclônica e confluente, vorticidade relativa ciclônica e convergência entre os dias -2 e 0 em baixos níveis, principalmente em 1000 hPa. Encontraram-se anomalias negativas de radiação de onda longa emergente (ROLE) e de omega e positivas de umidade relativa. A composição de precipitação indicou que são responsáveis por: 70% ou mais da chuva do período chuvoso do litoral norte de Alagoas (AL) ao leste do Rio Grande do Norte (RN)...

Descreve-se a ocorrência de infecção pelo vírus sincicial respiratório bovino (BRSV) em bezerros descendentes de animais das raças pardo-suíça e holandesa importados da Alemanha, Áustria, Suíça e Uruguai, na qual morreram em Alagoas, Brasil, pelo menos 220 cabeças, de 1995 até a presente data. O quadro clínico caracterizou-se por hipertermia, tosse seca, mais tarde dispnéia acentuada e por vezes lacrimejamento; à auscultação havia estertores secos, depois úmidos, com sibilos, muitas vezes audíveis à distância. O exame histológico revelou pneumonia intersticial com formação de células sinciciais, infiltração predominantemente linfocitária com presença de eosinófilos e de corpúsculos de Russel, proliferação de pneumócitos tipo II e leve metaplasia escamosa. Células epiteliais de bronquíolos e células sinciciais marcaram- se positivamente com o anticorpo anti-BRSV. A ocorrência da enfermidade no Sul e agora no Nordeste do Brasil indica a necessidade de se promover um amplo levantamento epidemiológico para se avaliar o grau de perdas e a proporção de animais infectados no país. Lembramos que parte dos animais importados, ao que tudo indica, já estavam infectados nos países de origem, quando desembarcaram em Belém...

Mestrado em Economia e Gestão de Ciência, Tecnologia e Inovação; This research has been conducted in the Brazil’s Northeast region, economically the weakest region in the country. A total of 35 business incubators (97%) and 93 firms (29%) were surveyed by questionnaire and interviews were conducted in 14 incubators in order to map the region’s incubators and to evaluate the practice and the possible impact of this economic development tool. In our analysis we found evidence of structural and administrative failures, absence of adequate business development and financial instability due to a low level of public investment. Since there is no clear policy, each incubator is an independent initiative of either a public or private university, a technology park, a science department of local government or a non-profit organization. The lack of adequate finance has as a consequence the prevalence of software firms on the expense of other innovative sectors and the abundance of part-time incubator and firm personnel and, more importantly, it also brings about part-time entrepreneurs. Apart of a relatively small fraction of strong and effective incubators, the majority of the surveyed incubators performs an incorrect firm selection process...

The influence of tidal and diel changes on the exchange of Petrolisthes armatus planktonic larvae was studied at the Catuama inlet, which represents an intermediate system of marine and estuarine environments in the Northeast Brazil. To characterize the larval abundance and vertical distribution, samplings were carried out in August 2001 at neap tide and 3 stations, with 3 hours interval over 24 hours. Samples were taken at three or two depths at each station, with a plankton pump coupled to a 300 µm mesh size net. Petrolisthes armatus zoea I and II showed a mean of 26.3 ± 83.6 and 12 ± 38.8 ind m-3, respectively. During flood tides, the larvae were more concentrated in the midwater and surface, which avoided the transport to internal regions. In contrast, during ebb tides when the larvae were distributed in the three layers, the higher concentrations were found in the bottom, which avoided a major exportation. The diel dynamic of the larval fluxes was characterized by vertical migration behavior associated to the tidal regime, which suggested that the development of this decapod apparently occurs in the inner shelf (instead of the outer shelf) off this peculiar ecosystem.

The irp2 gene codes for a 190 kDa protein (HMWP2) synthesidez when highly pathogenic Yersinia are grown under conditions of iron starvation. In this work, the presence of irp2 in strains of Y. pestis isolated from different hosts during several plague outbreaks in the foci of Northeast Brazil wasstudied. For this purpose, 53 strains were spotted onto nylon filters and their DNA was hybridized with the A13 probe which is a 1 kb fragment of the irp2 coding sequence. All strains except two hybridized with the probe. However, when the initial stock culture of these two strains were analyzed, they both proved to bepositive with the A13 probe, indicating that the locus was lost after subculturein vitro but was always present in vivo. To examine the degree of conservation of the chromosomal fragment carrying irp2 among Brazilian strains, the hybridization profiles of 15 strains from different outbreaks, different hosts and different foci were compared. The hybridization profiles of these strains were all identical when their DNA was digested with either EcoRI, EcorRV or AvaII, indicatingthat the restriction sites surrounding the irp2 locus are very well conserved among Northeast Brazilian strains of Y. pestis. Altogether, these results suggest that the irp2 chromosomal region should be of prime importance for the bacteria during their multiplication in the host.

Phylogenetic analysis of all 31 described mitochondrial (cytochrome b) haplotypes of Lutzomyia whitmani demonstrated that new material from the State of Rondônia, in southwest Amazônia, forms a clade within a lineage found only in the rain-forest regions of Brazil. This rain-forest lineage also contains two other clades of haplotypes, one from eastern Amazônia and one from the Atlantic forest zone of northeast Brazil (including the type locality of the species in Ilhéus, State of Bahia). These findings do not favour recognizing two allopatric cryptic species of L. whitmani, one associated with the silvatic transmission of Leishmania shawi in southeast Amazônia and the other with the peridomestic transmission of Le. braziliensis in northeast Brazil. Instead, they suggest that there is (or has been in the recent past) a continuum of inter-breeding populations of L. whitmani in the rain-forest regions of Brazil.

Population-based data on sexually transmitted infections (STI), bacterial vaginosis (BV), and candidiasis reflect the epidemiological situation more accurately than studies performed in specific populations, but such data are scarce. To determine the prevalence of STI, BV, and candidiasis among women of reproductive age from a resource-poor community in Northeast Brazil, a population-based cross sectional study was undertaken. All women from seven hamlets and the centre of Pacoti municipality in the state of Ceará, aged 12 to 49 years, were invited to participate. The women were asked about socio-demographic characteristics and genital symptoms, and thereafter examined gynaecologically. Laboratory testing included polymerase chain reaction (PCR) for human papillomavirus (HPV), ligase chain reaction (LCR) for Chlamydia trachomatis and Neisseria gonorrhoeae, ELISA for human immunodeficiency virus (HIV), venereal disease research laboratory (VDRL) and fluorescent treponema antibody absorption test (FTA-ABS) for syphilis, and analysis of wet mounts, gram stains and Pap smears for trichomoniasis, candidiasis, and BV. Only women who had initiated sexual life were included in the analysis (n = 592). The prevalences of STI were: HPV 11.7% (95% confidence interval: 9.3-14.7)...

From January to December 1998, nasopharyngeal aspirates were obtained from 482 children with acute respiratory infections attended in emergence department and wards of a teaching hospital in the city of Salvador, Brazil. The samples were tested for the presence of adenovirus by isolation in tissue culture and indirect immunofluorescence assay. Eleven adenoviruses were detected by both methods in the same clinical samples. Infections by adenovirus were observed during seven months of the year without association with rainy season. Genome analysis was performed on these 11 isolates. Species C was represented by serotypes 1, 2 and 5. Within species B, only serotype 7 (Ad7) was detected. Two genomic variants of Ad1, two variants of Ad2, one of Ad5, and one of Ad7 (7h) were identified. This is the first study of molecular epidemiology of adenovirus associated to acute respiratory infections in children living in Northeast Brazil, and contributes to a better understanding of adenovirus infections in the country.

Rotavirus is an important cause of childhood diarrhoea. A monovalent rotavirus vaccine (Rotarix®) was introduced into the Immunization Program of Brazil in 2006. In this study, we describe the incidence and burden of disease of rotavirus diarrhoea in two cohorts of children (vaccinated and unvaccinated). We followed two groups of 250 children under one year old, who were enrolled in December 2006 from a low-income residential area in Northeast Brazil. The children were monitored every two weeks for two years. Stool samples from children with diarrhoea were examined for the presence of rotavirus. Rotaviruses were genotyped using real time-polymerase chain reaction. The mean numbers of all-cause diarrhoea episodes/child (adjusted for age) in the first year were 0.87 and 0.84, in vaccinated and unvaccinated children, respectively. During the second year, the number of episodes/child decreased to 0.52 and 0.42. Only 16 (4.9%) of 330 stool samples were rotavirus-positive (10 vaccinated and 6 unvaccinated children) and only P[4]G2 rotaviruses were identified. All-cause diarrhoea episodes were more severe in unvaccinated children in the first year of age (p < 0.05), while vaccinated children had more severe episodes 18 months after vaccination. Rotavirus diarrhoea incidence was very low in both groups.

The 12-monthly running means centered 3 months apart (4 values per year) of the rainfalls in NE (Northeast) Brazil were subjected to Maximum Entropy Spectral Analysis and results compared with similar analysis for several other parameters. Characteristics of northern NE and eastern NE rainfalls were almost similar but differed considerably from those of southern NE rainfall. In the QBO region, northern NE had small periodicities at 2.03, 2.45 years, eastern NE had strong periodicities at 2.26, 2.60 years while southern NE had no significant QBO. The 50mb equatorial zonal wind had a strongest peak at 2.33 years, a smaller peak at 2.64 years and a still smaller peak at ~2.00 years. The Southern Oscillation Index T-D (Tahiti minus Darwin atmospheric pressure) had peaks at 2.05, 2.57 years while EEP-SST (equatorial eastern Pacific sea surface temperature) had peaks at 2.10, 2.57 years. (North and South Atlantic SST) had peaks at (2.10-2.15) years while NE Brazil coast SST had 2.29 years and Wind Stress had 2.20 years. In the QTO region, 50mb wind had a small peak at 3.2 years and NE coastal Wind Stress at 3.3 years. All other parameters including all the 3 regional rainfalls of NE Brazil had significant peaks near 3.5 years. Peaks were also in the (4.5-5.0) year and (9.5-13.9) year bands. All the three rainfalls had moderate correlations with T-D and EEP-SST (~0.3) and with 50mb wind (~0.4). Rainfall correlations were higher with North and South Atlantic SST (~0.5) and with NE coastal SST (~0.6). The eastern NE rainfall had a high correlation (0.5) with NE coastal Wind Stress.

Imposex is characterized by the development of masculine sexual organs in neogastropod females. Almost 120 mollusk species are known to present imposex when exposed to organic tin compounds as tributyltin (TBT) and triphenyltin (TPT). These compounds are used as biocide agents in antifouling paints to prevent the incrustations on boats. Five gastropod species are known to present imposex in Brazil: Stramonita haemastoma, Stramonita rustica, Leucozonia nassa, Cymathium parthenopeum and Olivancillaria vesica. This paper reports the first record of imposex observed in the endemic gastropod Voluta ebraea from Pacheco Beach, Northeast Brazil. Animals presenting imposex had regular female reproductive organs (capsule gland, oviduct and sperm-ingesting gland) and an abnormal penis. As imposex occurs in mollusks exposed to organotin compounds typically found at harbors, marinas, shipyards and areas with high shipping activities, probably contamination of Pacheco Beach is a consequence of a shipyard activity located in the nearest areas.

The need to establish the long-term precipitation led many authors to try to understand why regulators of interannual climate variability over the Northeast of Brazil. Fluctuations in the equatorial Pacific SST acts as a modulator of climate on various time scales and are associated with the phenomenon (El Niño / Southern Oscillation). We analyzed the patterns of monthly and quarterly precipitation in Northeast Brazil (with emphasis on the eastern part of Northeast Brazil), related to the anomalies of surface temperatures of the equatorial Pacific and south Atlantic, from the SST data obtained from the Comprehensive Ocean-Atmosphere Data System and precipitation data from the universe as we know from Delaware from 1950 to 1999. The monthly precipitation by the phases of the Pacific Decadal Oscillation and rainfall were arranged both quarterly and lag. Were defined conditions of El Niño: positive anomaly; positive derivative; positive derivative if and only if the anomalies were positive and the anomaly index Interoceanic (AI). The best parameter for prediction of quarterly rainfall within the rainy season in NE, was the condition of positive derivative of the SST of the Pacific, one month before the rain (lag1) with positive correlation of 0.3 to 95% of significance...

Abstract: The variation in the onset of puberty in ewe lambs is influenced by both genetic and environmental factors. Identification of the specific factor and its influence in relation to other factors is unclear. The age and live body weight at which ewe lambs show the first puberal estrus are of considerable practical importance. Ewe lambs showing early sexual activity have increased lifetime performance and hada higher reproductive efficiency in the adult ewe. An attempt has been made to study puberty in terms of age, live body weight, breed and ovarian activity at the onset of puberty (first behavioral estrus) of hair sheep in Northeast Brazil.

In this study, an empirical method proposed by Caselles et al. (1992a) is utilized to determine the potential evapotranspiration (ETP) on a regional scale. This method uses the global solar radiation data retrieved by the global radiation model GL1.0, which in turn utilizes data from the visible channel of the GOES-8 satellite. This method is applied to the northeast region of Brazil, using daily and monthly climatological data as the ground truth information to estimate the ETP and the estimated daily ETP data for September, 1997. The methodology involved three steps: 1) to perform a spatial regionalization of the ETP using the method of Ward, which is available in the Statistical Package for the Social Sciences (SPSS); 2) to obtain the correlation between the ETP as estimated by the methods of Jensen & Haise (1963) - MJH, Caselles (1992a) - MCA, and the Penman's combined method (1948) - MCP; 3) to test the sensibility of the empirical formulations proposed and to assess the estimates using the satellite-based global solar radiation provided by the GL1.0 model. The spatial regionalization shows two distinct regions in the Northeastern Brazil. The MCA yielded better results than the MJH. The ETP estimates using satellite data were satisfactory...

Aquaculture is the fastest growing sector of food production in the world. However, rapid expansion of shrimp aquaculture ponds may induce potentially detrimental changes in extent and health of coastal habitats utilized by migratory shorebirds. The aim of this work is to describe the landscape changes that occurred between 1990 and 2006 in coastal Northeast Brazil as a result of increased shrimp pond development. A suite of remote sensing techniques was employed to process Landsat and ASTER imagery at three separate time periods (1990, 2000 & 2006) and generate land cover maps for each time period. Post-classification change detection analysis revealed critical conversions between identified coastal habitat types in Northeast Brazil. The results of this study revealed a substantial growth of shrimp aquaculture facilities on the northern coast of Northeast Brazil between 1990 and 2006. Contrary to the literature, the expansive tidal salt flats in the study area, not mangrove forests, are experiencing the greatest destruction as a result of shrimp aquaculture. Research and management efforts should be directed at determining the extent of utilization of these salt flat areas by migratory shorebirds.
