    The Taciba and Rio Bonito ('lower' Triunfo Mbr) formations are divided into six depositional sequences based on cores, gamma-ray and electrical logs from shallow drillings from northern Santa Catarina State, Brazil. Each sequence is formed by two systems tracts, a lower one, sandy (low stand) and an upper one, shaly (high stand). The Taciba Formation has three sequences, S{sub 0} to S{sub 2}; sequence S{sub 0} has a thick turbidite sandstone at the base (Rio Segredo Member) that pinches out towards the eastern margin and even disappears in the Mafra outcrop area. Sequence S{sub 1} varies from a thin fluvial-estuarine system to a thick turbidite sandstone of a channelled fan system; S{sub 1} upper shaly system tract is marine in well PP-11, and it is glacially influenced in well PP-10. Sequence S{sub 2} is a thick sandstone body of shallow marine origin, but restricted to one well (PP-11); its upper shaly tract is dominated by massive siltstones intercalated with thin, distal tempestites. The 'lower' Triunfo Member (or 'Taciba- Triunfo transition') begins with the arrival of deltaic clastics of sequence S{sub 3} lower tract, coarsening-up from medial- to proximal delta front sandstones. Sequence S{sub 4} is quite similar to S{sub 3}, both showing sandstone pro gradation from north to south, as opposed to the southwest-sourced transgressive diamictites. Sequence S{sub 5} consists of fluvial deposits at well PP-12, and two transgressive cycles from wells PP-11 to PP-9, each one of them composed of fluvial-estuarine to marine systems. Well PP-10 is an exception, where the lower cycle presents de glaciation to marine deposits. (author)

  2. A radicalidade de Os Parceiros do Rio Bonito

    Full Text Available O livro Os parceiros do Rio Bonito traz uma contribuição admirável ao pensamento social brasileiro por sua relevância ético-política, como obra de denúncia política e crítica social; por sua contribuição formal ou estética, uma fina arquitetura da palavra e da argumentação sociológica e antropológica; e por sua contribuição metodológica, a pertinência do ato crítico aberto e pautado pela fluidez, em contraposição à adesão irrestrita a determinado aparato teórico. À atitude crítica associa-se a atitude mental de empatia pelo objeto, que se afasta de um frio e distante "sociologismo", mas, ao mesmo tempo, se recusa a atribuir-lhe as características que "gostaríamos" que tivesse, conforme a ideologia ou as crenças que partilhamos. A radicalidade dessa obra reside no espírito aberto para a "aventura sociológica", daí resultando a inexistência de "manifestos"ou "normas" de conduta. Todavia, Candido demarca os limites entre o espírito aberto à diversidade e à versatilidade no trato do fenômeno social, de um lado, e a adesão aventureira a um relativismo estéril, de outro. Finalmente, discute-se aqui a íntima relação entre a conduta intelectual do autor - sua postura ética diante do mundo acadêmico - e sua própria obra.

    Full Text Available O objetivo deste trabalho é investigar o papel das estruturas subjacentes associadas à evolução tectônica regional e o seu reflexo na geomorfologia, a partir de uma abordagem morfotectônica na bacia do rio Bonito, localizada no extremo norte do município de Petrópolis, Planalto Serrano do Estado do Rio de Janeiro. As estruturas identificadas na área correspondem a falhas e famílias de juntas, que estão relacionadas com as descontinuidades de caráter regional e diretamente associadas ao contexto geológico regional ao qual se inserem, exibindo condições significativamente marcadas pelos processos vinculados à ruptura continental e abertura do Oceano Atlântico, iniciados a partir do Jurássico Superior, especialmente pela reativação de descontinuidades preexistentes. O controle tectônico-estrutural se reflete na compartimentação morfotectônica a partir (ada integração dos dados estruturais, da análise dos lineamentos da rede de drenagem, que definem trends de lineamentos que correspondem a estruturas identificadas e medidas, (b do relevo, que apresenta escalonamentos e o desenvolvimento de vales suspensos, e (c da distribuição espacial da cobertura sedimentar que reproduz a complexidade de feições observadas tanto no contexto local quanto no regional. Dessa maneira, tendo como princípio que a tectônica influencia diretamente a evolução da paisagem, os dados obtidos mostram uma interferência direta das estruturas na compartimentação morfotectônica e na dinâmica e evolução da paisagem da área em estudo.

    Full Text Available This research was developed in the city of New Friburgo, more precisely in the seventh section – Lumiar – Rio Bonito. The inexistence in the region of educational actions aimed at understanding, reflecting and offering information to the population on the main environmental subjects has leaded to an environmental diagnosis, to identify the local community problems and, later, to develop educational environmental activities at municipal school Nossa Senhora de Nazareth. To attain this aim, the selected educational strategy was story telling. The research instrument was a questionnaire addressed to the families and to the teachers. Based on the principal detected problems, the ones related to environmental issues were selected, such as: river pollution; the release of solid residues in not appropriate places and the armed hunting. Those subjects were discussed with the local school students through story telling. Other playful educational activities were also developed. Finally, it could be observed that, not only the stories, but also the complementary activities, have helped the students in the environmental education work, considering that besides showing interest in the subject, they participated intensely, reflected, changed and built knowledge.

    The Rio Claro and Piracununga formations cover extensive areas of the Paulista Peripheral Depression, dominantly in the region of Rio Claro and Piracununga cities. These units lie over the Corumbatai and Piramboia formations, exhibiting discordant contacts. The Rio Claro and Piracununga formations are composed of fine to medium sand facies, showing local cross-stratifications and parallel beddings with thin interbeddings of mud and gravel. These sands were dated by the Thermoluminescence Method, which indicated they were from the Pleistocene age. The oldest age (745,000 years BP) was found in deposits of the Rio Claro Formation; the other ages varied from 400,000 years BP to 145,000 years BP, for both formations. The youngest age (15,000 years BP - close to Pleistocene/ Holocene limit) was found in colluvial deposits, which rest on the Piracununga Formation. (author)

    The geological results obtained in the Candiota Region by NUCLEBRAS, during the evaluation of the uranium economic potential from basal Gondwana Sequence - Itarare Group and Rio Bonito Formation - at South-East of the Parana Sedimentary Basin, are studied. The analysis of 18 geologic sections (scales 1:5.000 x 1:500), 21 drill holes and fotogeologic interpretation in the scale 1:50.000, are included. The Itarare Group sedimentation was conditioned by paleo - relief with valleys formed from differential erosion on 'horst - graben' structures. The deposition of its rhythmites, diamictites and siltstones was made in periglacial and marine environments. The sedimentation of the Rio Bonito Formation is related to the main Itarare Group depositional axes. The typical lithologies are: sandstones, siltstones, mudstones and coals, representing progradational fluvial sediments over coastal - plain areas. (Author) [pt

    This work is a study of the {sup 40}K and the {sup 238}U and {sup 232}Th series radioactivity in rocks measured with high resolution gamma ray spectrometry. The rocks were taken from the geologic formations in the region of the Tibagi river hydrographic basin. The course of this river cuts through the Paleozoic and Mesozoic stratigraphic sequences of the Parana sedimentary basin. In order to take into account the background radiation attenuation by the samples, a technique was developed that eliminated the need to measure a blank sample. The effects of the radiation's self-attenuation in the sample matrix were taken into account by using a gamma ray direct transmission method. The results for 87 rock samples, taken from 14 distinct formations, and their corresponding radioactivity variations are presented and discussed according to the possible geological processes from which they originated. Among the most discussed results are: an outcrop that profiles shale, limestone and rhythmite in the Irati Formation; a sandstone and siltstone sequence from the Rio do Rasto Formation; and a profile sampled in a coal mine located in the Rio Bonito Formation. The calculations of the rocks' contributions to the outdoor gamma radiation dose rate agree with the values presented by other authors for similar rocks. The highest dose values were obtained from felsic rocks (rhyolite of the Castro group, 129.8 {+-} 3.7 nGy.h{sup -1}, and Cunhaporanga granite, 167 {+-} 37 nGy.h{sup -1}). The other highest values correspond to the shale rocks from the Irati Formation (109 {+-} 16 nGy.h{sup -1}) and the siltic shale rocks from the Ponta Grossa Formation (107.9 {+-} 0.7 nGy.h{sup -1}). The most recent geological formations presented the lowest dose values (e.g. the Botucatu sandstone, 3.3 {+-} 0.6 nGy.h{sup -1}). The average value for sedimentary rocks from seven other formations is equal to 59 {+-} 26 nGy.h{sup -1}. The Rio Bonito Formation presented the highest dose value (334

    There is a pressing need for the development of ways of preparing palatable salt-reduced foods to reduce the salt intake of the Japanese population. The salt-reducing effect of the characteristic flavors other than umami of dried bonito stock, which is widely used in everyday Japanese food, was examined by sensory evaluation. In the 1st sensory evaluation, the effect was evaluated in a model solution. The saltiness of 0.80% NaCl solution was equivalent to that of 0.12% monosodium glutamate (MSG) solution containing 0.81% NaCl and dried bonito stock containing 0.68% NaCl. Saltiness enhancement could not be found when MSG solution was used, but was found with 6% dried bonito stock. The 2nd evaluation examined whether the effect was valid for 2 everyday Japanese foods--traditional Japanese clear soup (sumashi-jiru) and steamed egg custard (tamagodoufu). Although enhancement of saltiness by dried bonito stock could not be clearly demonstrated in the soup, a change in NaCl concentration within 15% did not affect the palatability of the soup. However, dried bonito stock not only enhanced the saltiness but also improved the palatability of steamed egg custard. These findings are expected to be useful for improving the palatability of salt-reduced food.

    Recent discoveries of oil in microbial carbonate rocks have directed studies into tufas and travertines because of their great similarities with the reservoir rocks of the Aptian Pre-Salt. Tufas are continental carbonate rocks precipitated from a bicarbonate fluid at environment temperature. The genesis of tufas is related to physical, chemical, and biological processes. Here, we present a study of a modern tufa samples belong to the Serra da Bodoquena Formation - Bonito, Brazil, which is located in a special climatic regime where a well-defined seasonal cycle of wet and dry conditions occurs. This area was examined with purpose to understand the chemical conditions of the depositional environment and microorganisms involved in their formation. Field descriptions provided the following facies: i) phytoherm, formed by the accumulation of leaves, branch fragments and bryophytes cushions; ii) shrubs that are radii-fibers structures related to crystallization processes of bacteria filaments; and, iii) stromatolites, made by intercalation of laminas of micrite and shrubs. Pools, barriers and cascade/waterfall were identified as the main depositional environment, which are included to the fluvial depositional model. SEM images showed several cyanobacterial filaments. Organic composition showed the presence of n-alkanes and sterols. Results of XRD and XRF indicate the presence of calcite and, locally, quartz. A depletion of the δ18O indicates a fluid of meteoric origin, which is compatible with the literature for tufas. The presence of cyanobacteria and other photosynthetic organisms, besides the influence of light carbon soil is related with low values of δ13C. Palynological analysis revealed palynomorphs of fungus, hyphae, pteridophyte spores and pollen grains, which indicate a humid environment with abundant vegetation, typical of tropical climate. In conclusion, the biomineralization process, characterized by the variations of the physico-chemical conditions in this

    Full Text Available A review of published papers and results of analysis of new material have allowed improvements on the palynostratigraphy of the Permian strata of the Paraná Basin in Rio Grande do Sul State. Based on first and last occurrences of certain species of pollen taxa, two palynozones are formalized, these are the Vittatina costabilis and Lueckisporites virkkiae Interval Zones, in ascending order. The Vittatina costabilis Interval Zone is subdivided into two units, in ascending order the Protohaploxypinus goraiensis and the Hamiapollenites karrooensis Subzones, and is recognized from the glacial (Itararé Group and post-glacial sequence (Rio Bonito Formation and the base of the Palermo Formation. The Lueckisporites virkkiae Interval Zone occurs from the uppermost Rio Bonito Formation, through the Palermo and Irati formations, and into the Serra Alta and Teresina formations. The main characteristics and reference sections are established, as well as additional criteria to recognize biostratigraphical units, in accordance with the International Stratigraphic Guide. Palynostratigraphical correlation suggests that the Vittatina costabilis Zone concerns the Early Permian (early Cisuralian, while the Lueckisporites virkkiae is regarded as late Early Permian to early Middle Permian (late Cisularian to early Guadalupian.

    The trace elements Zr, Y, Sr, U, Rb, Th, Ga, Pb, Zn, Cu, Ni, Co, Cr, Ce, Ba and La were determined by X-Ray fluorescence spectroscopy on samples from shales, carbonaceous shales, coal and fine-grained groundmass of a paraconglomerate ( pedra-areia ) colleted from the Papaleo and Faxinal outcrops and from the Faxinal Coal Mine, Guaiba, RS. The analysis pointed out an association of zirconium, copper, uranium and thorium with coal and carbonaceous rocks, whereas barium and galium are related to inorganic rocks. The other elements showed neither preferential relationships with organic nor inorganic matter. The extremely high contents of uranium, cerium and lanthanum in the upper coal layers in both Papaleo and Faxinal outcrops suggest an association with the top of the Rio Bonito Formation in this area.

    Full Text Available Paleomagnetic and rockmagnetic data are reported for the aeolian Botucatu Formation, in the southern Brazilian State of Rio Grande do Sul. Oriented samples were taken from a section located between the cities of Jaguari and Santiago. After thermal and alternating field demagnetization, both normal and reversed characteristic remanent magnetizations were found. These results yielded 13 reversed and 5 normal polarity sites, composing a magnetostratigraphic column displaying a sequence of reversed-normal-reversed polarity events. The paleomagnetic pole calculated for 18 sites is located at 114.7ºE, 78.5ºS (dp=8.1º; dm=1.2º, after restoring the strata to the paleohorizontal. This paleomagnetic pole indicates a Late Jurassic-Early Cretaceous age to the Botucatu Formation in the investigated area, and places the sampling sites at paleolatitudes as low as 21ºS.Dados paleomagnéticos e de magnetismo de rochas dos sedimentos eólicos da Formação Botucatu, no Estado do Rio Grande do Sul, obtidos de uma seção localizada entre as cidades de Jaguari e Santiago, permitiram definir a idade dessa formação.

    2016-01-01

    In the southwestern United States (US), the Rio Grande chub (Gila pandora) is state-listed as a fish species of greatest conservation need and federally listed as sensitive due to habitat alterations and competition with non-native fishes. Characterizing genetic diversity, genetic population structure, and effective number of breeders will assist with conservation efforts by providing a baseline of genetic metrics. Genetic relatedness within and among G. pandora populations throughout New Mexico was characterized using 11 microsatellite loci among 15 populations in three drainage basins (Rio Grande, Pecos, Canadian). Observed heterozygosity (HO) ranged from 0.71–0.87 and was similar to expected heterozygosity (0.75–0.87). Rio Ojo Caliente (Rio Grande) had the highest allelic richness (AR = 15.09), while Upper Rio Bonito (Pecos) had the lowest allelic richness (AR = 6.75). Genetic differentiation existed among all populations with the lowest genetic variation occurring within the Pecos drainage. STRUCTURE analysis revealed seven genetic clusters. Populations of G. pandora within the upper Rio Grande drainage (Rio Ojo Caliente, Rio Vallecitos, Rio Pueblo de Taos) had high levels of admixture with Q-values ranging from 0.30–0.50. In contrast, populations within the Pecos drainage (Pecos River and Upper Rio Bonito) had low levels of admixture (Q = 0.94 and 0.87, respectively). Estimates of effective number of breeders (N b ) varied from 6.1 (Pecos: Upper Rio Bonito) to 109.7 (Rio Grande: Rio Peñasco) indicating that populations in the Pecos drainage are at risk of extirpation. In the event that management actions are deemed necessary to preserve or increase genetic diversity of G. pandora, consideration must be given as to which populations are selected for translocation.

    Katsuobushi is a dried, smoked and fermented bonito used in Japanese cuisine. During the fermentation process with several Aspergillus species, the colour of Katsuobushi gradually changes from a dark reddish-brown derived from haem proteins to pale pink. The change in colour gives Katsuobushi a higher ranking and price. This study aimed to elucidate the mechanism of decolourisation of Katsuobushi. A decolourising factor from the culture supernatant of Aspergillus (Eurotium) repens strain MK82 was purified to homogeneity. The purification was monitored by measuring the decolourising activity using equine myoglobin and bovine haemoglobin as substrates. It was found that the decolourising factor had protease activity towards myoglobin and haemoglobin. Complete inhibition of the enzyme by the inhibitor pepstatin A and the internal amino acid sequence classified the protein as an aspartic protease. The enzyme limitedly hydrolysed myoglobin between 1-Met and 2-Gly, 43-Lys and 44-Phe, and 70-Leu and 71-Thr. The purified enzyme decolourised blood of Katsuwonus pelamis (bonito) and a slice of dried bonito. It is proposed that aspartic protease plays a role in the decolourisation of Katsuobushi by the hydrolysis of haem proteins that allows the released haem to aggregate in the dried bonito. © 2012 Society of Chemical Industry.

    Full Text Available The 2012 elections for governor in Rio de Janeiro gather special attention from national and international media analysts. The city politics was under scrutiny with the mega events hosted Brazil, like the Summer Olympic Games and the Soccer World Cup. In this sense, the strategies of the candidates for the organization of the city - mainly for public safety issues - were dissected and analysed for months leading up to the election day. In this context, as the disputes were being centralized in the candidates best placed in the pools, Luis Carlos Pezão (PMDB and Marcelo Crivela (PRB, talks about the supposed contenders’ governance mechanisms began to be galvanized. In the mainstream narrative, the first one would gather support, along other segments, from the “milícias”, parastatal organizations that uses extortion of some communities to gather control of entire neighbourhoods. The ‘milícias’ would be one of the greatest contemporary security issues of Rio, accused of violent actions and recurrent cases of murders and violence. In turn, Crivela would be mainly supported by the neo-Pentecostal religious groups (The Guardian, 2012; O Globo, 2012. This binary narrative, reinforced by accusations from both politicians in televised debates, strengthened the discourse of an ‘ militia assault’ against the State, building the image that evangelical sectors could serve as an opposition movement to these groups. Both would operate on a complete and antagonic mechanism of governance and social organization. The objective of this paper is to critically deconstruct these two premises. First, through a genealogical analysis of milícias groups in Rio de Janeiro, we will establish a reflection that these agents never behaved as "parallel states", as often described. Far from "invading the State," such actors establish enmeshment processes with government sectors, redefining practices and legitimacy in a complex system - involving elections and

    This paper aimed to characterize the anatomical structure of the wood of specimens of Mollinedia glabra (Spreng.) Perkins growing in two contiguous formations of restinga vegetation at Praia Virgem, in the municipality of Rio das Ostras, RJ. Both the Open Palmae (OPS) and the Sandy Strip Closed Shrub (SSCS) formations are found in coastal regions that receive between 1,100 and 1,300 mm of rainfall per year. Sapwood samples were collected in both formations. Typical anatomical features for this species include: solitary vessels, radial multiples or clusters elements, that are circular to angular in outline, 5-15 barred scalariform perforation plates, wood parenchyma scanty, septate fiber-tracheids, and wide multiseriate rays with prismatic crystals. Statistical analyses indicated a significant increase in the frequency of vessel elements and an increase in fiber-tracheid diameters in OPS individuals. These characteristics are considered structural adaptations to increased water needs caused by a greater exposure to sunlight. Continuous pruning may be responsible for the tyloses observed in OPS plants. The greater lengths and higher frequencies of the rays in SSCS trees may be due to the greater diameters of their branches. Our results suggest that M. glabra develops structural adaptations to the restinga micro-environmental variations during its development.

Therefore, the management of side effects is essential for the longer period of continuous medication. Among the various side effects, hand–foot syndrome (HFS is the most common, occurring in 30%–50% of patients, and often results in discontinuation of the SOR medication. However, its mechanism has not been clarified, and no effective prevention method has been reported for the symptoms. Therefore, this study aimed to analyze its mechanism and to develop an effective prevention regimen for the symptoms. Materials and methods: To assess the mechanism of SOR-induced HFS, the peripheral blood flow in the hand and foot was carefully monitored by Doppler ultrasound, thermography, and laser speckle flowgraphy in the cases treated with SOR and its contribution was assessed. Then, the effect of dried-bonito broth (DBB, which was reported to improve peripheral blood flow, on the prevention of the symptom was

    Full Text Available This study aimed to provide information about the population structure and somatic index of Hypostomus cf. ancistroides collected from the Bonito river, located in the Ivaí river basin. The length-weight relationship was isometric for both the sexes. The length structure analysis showed that the larger individuals (from 18.1cm to 27.0cm in length predominated, and the lowest abundances occurred at the size extremes (9.1-12cm and 27.1-30.0cm. The reproduction period occured between October and January for the females and between November and January for the males. The liver somatic index cannot be used as an indicator of the reproduction period in either of the sexes, due to no correlation between the liver somatic index and the gonad somatic index. The gonad weight exerted no influence on the monthly mean condition factor and the correlation between the condition factor and gonad somatic index was high. The condition factor could be an indicator of the reproduction period of this species.Este estudo teve o objetivo de fornecer informações sobre a estrutura populacional e os índices somáticos de Hipostomus cf. ancistroides coletados no rio Bonito localizado na bacia do rio Ivaí.

    This work is a study of the 40 K and the 238 U and 232 Th series radioactivity in rocks measured with high resolution gamma ray spectrometry. The rocks were taken from the geologic formations in the region of the Tibagi river hydrographic basin. The course of this river cuts through the Paleozoic and Mesozoic stratigraphic sequences of the Parana sedimentary basin. In order to take into account the background radiation attenuation by the samples, a technique was developed that eliminated the need to measure a blank sample. The effects of the radiation's self-attenuation in the sample matrix were taken into account by using a gamma ray direct transmission method. The results for 87 rock samples, taken from 14 distinct formations, and their corresponding radioactivity variations are presented and discussed according to the possible geological processes from which they originated. Among the most discussed results are: an outcrop that profiles shale, limestone and rhythmite in the Irati Formation; a sandstone and siltstone sequence from the Rio do Rasto Formation; and a profile sampled in a coal mine located in the Rio Bonito Formation. The calculations of the rocks' contributions to the outdoor gamma radiation dose rate agree with the values presented by other authors for similar rocks. The highest dose values were obtained from felsic rocks (rhyolite of the Castro group, 129.8 ± 3.7 nGy.h -1 , and Cunhaporanga granite, 167 ± 37 nGy.h -1 ). The other highest values correspond to the shale rocks from the Irati Formation (109 ± 16 nGy.h -1 ) and the siltic shale rocks from the Ponta Grossa Formation (107.9 ± 0.7 nGy.h -1 ). The most recent geological formations presented the lowest dose values (e.g. the Botucatu sandstone, 3.3 ± 0.6 nGy.h -1 ). The average value for sedimentary rocks from seven other formations is equal to 59 ± 26 nGy.h -1 . The Rio Bonito Formation presented the highest dose value (334 ± 193 nGy.h -1 ) mainly due to the anomalous 226 Ra

    Full Text Available ABSTRACT: Magmatism associated with the Alto Paranaíba structural high comprises kimberlites, kamafugites, and alkaline complexes, forming an approximately 400 x 150 km NW-SE belt in the southern São Francisco Craton. Dating of some intrusions reveals ages between 120 and 75 Ma. Chemical analyses of garnet recovered in alluvium from traditional diamond digging areas indicate peridotitic garnet windows in Três Ranchos and Coromandel. Six hundred and eighty (680 diamonds acquired or recovered during mineral exploration in the digging areas of Romaria, Estrela do Sul, Três Ranchos and Coromandel show unique characteristics, certain populations indicating young, proximal and primary sources (YPP. Analyses of 201 stones from Santo Antônio do Bonito, Santo Inácio and Douradinho rivers alluvium, Coromandel, present no evidence of transport, characterizing a proximal source. Within these river basins, exposures of the Late Cretaceous Capacete Formation basal conglomerate contain mainly small rounded and/or angular quartzite pebbles and of basic and ultrabasic rocks, as well as kimberlite minerals (garnet, ilmenite, spinel, sometimes diamond. A magnetotelluric profile between the Paraná and Sanfranciscana basins shows that the thick underlying lithosphere in the Coromandel region coincides with the peridotitic garnet window and with a diamond population displaying proximal source characteristics. Diamond-bearing kimberlite intrusions occur in different areas of Alto Paranaíba.

    Sedimentary facies from the Candeleros Formation (Rio Limay Subgroup), cropping out at the El Escondido creek, at the Ezequiel Ramos Mexia dam, are analyzed and interpreted in this paper. A sedimentological detailed section was measured to get the main goal of this paper which is the sedimentary paleoenvironment. The outcroppings were pictured and a section was measured, geometries and espacial relation between them were analyzed. Eight lithofacies were identified which are: coarse sandstone facies (Se), sandstones (Sm, St, Sp, Sh t Sr), siltstones and shales (Fl and Fr). These lithofacies were agrupated into eight facies associations (FA). AFA constitutes the registration of multiepisodic events of sheet floods; AFB, C and D are product of the depositation in a braided channel belt, AFE represents units of lateral accretion, AFF is assigned deposits of crevasse splay and AFG and H are assigned to plain of flood. The distribution of these associations in the column defines an terminal fan paleoenvironment where is represented of base to top: distal (AFA, B and G) and proximal area (AFD and G) of the distributary plain; zone of feeding of the system (AFC, And, F and G), media-proximal distributary plain (AFD and F), proximal distributary plain (AFC, And, F and G); and flood basin (AFF, G and H) [es

    Staphylococcus epidermidis is a leading cause of hospital-acquired infections, mostly associated with the use of medical devices in seriously ill or immunocompromised patients. Currently, the characteristics of methicillin-resistant S. epidermidis (MRSE) isolates from Rio de Janeiro hospitals are unknown. In this study, staphylococcal chromosomal cassette mec (SCCmec) types, antimicrobial susceptibility profiles, biofilm formation genes, and multilocus sequence types (MLST) were investigated in 35 MRSE clinical isolates. The collection of isolates was previously well characterized by pulsed-field gel electrophoresis (PFGE) into 2 main genotypes (A and B, 22 isolates) and 10 sporadic genotypes (13 isolates). MLST revealed a total of 8 different sequence types (STs), but ST2 and ST23, which were icaAB-positive, represented the majority (71.4%) of MRSE isolates tested. Almost all isolates (91.4%) belonged to clonal complex 2. SCCmec types III and IV were identified among 71.4% of the isolates, while the remaining was nontypeable. The predominant MRSE genotypes were defined as SCCmec type III/ST2 (PFGE type A) and SCCmec type IV/ST23 (PFGE type B) isolates, which were both associated with high antimicrobial resistance and presence of biofilm-related genes.

    Located in the south-western part of Brazil, the state of Rio de Janeiro is geotectonically contained within a complex structural province that resulted in the amalgamation of the Western Gondwana Paleocontinent. To undertake an extensive radiological characterization of this complex geological province and investigate the influence of bedrock, soil type and soil chemical-physical characteristics on natural radionuclide levels in soils, 259 surface soil samples were collected that encompassed the main soil types and geological formations throughout the state. Gamma spectrometry analysis of the samples resulted in median values of 114 Bq.kg -1 for 40 K, 32 Bq.kg -1 for 226 Ra and 74 Bq.kg -1 for 228 Ra. The median value for 226 Ra was similar to the world median value for soils, the 40 K value was well below the worldwide value, and that for 228 Ra exceeded the world median value. The intense weathering caused by the high rainfall rates and high temperatures may be responsible for the low levels of 40 K in the soils, of which the strongly acidic and clayey soils are markedly K-depleted. A soil from a high-grade metamorphic rock (granulite) presented the lowest 226 Ra (18 Bq.kg -1 ) content, whereas the highest levels for 226 Ra (92 Bq.kg -1 ) and 228 Ra (139 Bq.kg - 1) were observed in a young soil enriched in primary minerals (Leptsol). A lowland soil (Gleysol) showed the highest median of 40 K (301 Bq.kg -1 ). Strongly acidic soils tended to present high amounts of 226 Ra, and sandy soils tended to contain low levels of 228 Ra. The external radiation dose indicates that the state has a background radiation level within the natural range. Copyright © 2017 Elsevier Ltd. All rights reserved.

  1. The formation of early settled villages and the emergence of leadership: A test of three theoretical models in the Rio Ilave, Lake Titicaca Basin, southern Peru

    Science.gov (United States)

    Craig, Nathan Mcdonald

    Despite obvious necessities for understanding later developments in the region, Preceramic cultures in the Titicaca Basin are poorly understood due to lacking empirical data. This dissertation focuses on examination of two processes occurring in the Rio Ilave drainage during the Late 5000--3100 B.C.E. (6000--4400 B.P.) and Terminal 3100--1500 B.C.E. Archaic (4400--3200 B.P.): the formation of settled villages and the emergence of leadership. These processes are tested against theoretical predictions derived from: population resource imbalance, human behavioral ecology, and agency theories. Resource imbalance theory predicts appearance of density dependent adaptive problems prior to major cultural transformations. Human behavioral ecology predicts increased dietary diversity and incorporation of greater processing costs occuring coincidentally with reduced residential mobility. Symbolic mate value advertising is a predicted leadership strategy. Agency theory predicts internal sources of social tension, potentially independent of external forces, as primary causes of cultural change. Feast hosting and the formation political economy are expected to be central to both social processes investigated from this perspective. Local paleoclimatic proxies suggest aridity from ca 4000--2000 B.C.E. Reanalysis of pedestrian survey data indicate population growth during the Late Archaic. Excavation and ground penetrating radar survey at Pirco and Jiskairumoko demonstrate reduced residential mobility and increased evidence for social differentiation appearing during the Late Archaic's (before 3000 B.C.E.) end. New cultural patterns include: pithouses, more groundstone, internal storage, costly non-local artifacts, domesticated plants and animals, costly grave goods, and use of ochre in symbolic contexts. No clear cut evidence for inter-community promotional feasting was identified but some finds suggest intra-community alliance feasts. By the end of the Terminal Archaic ca. 1500 B

    This work aims to analyze the impact of the construction of a hydroelectric power plant on land cover and use in Lajeado Bonito-RS watershed. The study evaluated the temporal evolution of land cover and use in the watershed for the period before and after to installation of hydroelectric plant Foz do Chapeco (2009 to 2010). For temporal analysis, two images were interpreted, one orbital image of High Resolution Camera (HRC) onboard of the CBERS-2B, acquired in December 29, 2009. And a high-resolution image obtained from Google Earth application, acquired at December 26, 2010. The land cover and use maps were generated by vector editing SPRING software. We found that the predominant land use related to agriculture and livestock, including bare soil. In 2009 this class accounted for 70.23% of the total area, while it come to represent 61.8% in 2010. At the same time, there was increase of areas with native forest cover, from 27.49% covered by forest in 2009, to 31% in 2010. The results showed that in both 2009 and 2010 years, approximately 49% of permanent preservation area were used inappropriately. (author)

    At the world-wide Earth Summit held in Rio de Janeiro in 1992, two new legally binding documents were signed by over 140 countries: the Convention on Climate Change and the Convention on Biological Diversity. These conventions will come into force when ratified by 50 and 30 countries respectively. The objectives of these conventions, the steps to be taken toward their compliance, and their implications for Canada are discussed. Since climatic change could bring about adverse effects such as water shortages and loss of permafrost, Canada has committed itself to a quick start toward compliance with preparation of a detailed national inventory of greenhouse gas emissions. The biodiversity convention could make it harder to develop hydropower in Canada at the same time that the climate change convention makes hydropower more attractive. Other documents from the Earth Summit included declarations on forestry management, sustainable development, and future conventions on desertification and fishing. Notable features of the summit included a refocusing of the environmental agenda to the priorities of the poorer countries, a recognition that environmental issues are linked to poverty and economic development, and an attack on the consumption patterns of the richer countries.

    Full Text Available This paper presents the hydrogeological and hydrochemical characterization of the unconfined aquifer located in the alteration mantle in the volcanic rocks from Serra Geral Formation, in the northeast region of Rio Grande do Sul State. This aquifer is conditioned by the soil, topography, lithology and climate, being characterized by a saturated layer thinner than 1,7 m, static levels between 0 and 1 m and low flow (<0,5 m3/h. These waters are of calcium or magnesium bicarbonate type, and low alkalinity and electrical conductivity, low calcium, magnesium, sodium, potassium and chloride concentrations, and high iron and manganese concentrations. Additionally, these waters have high concentration of nitrates (mean above 10 mg/L and the presence of total coliforms. These characteristics evidence a quick circulation between the recharging and discharge zones in the aquifer.

    A 2 m-thick spheroidal weathering profile, developed on a quartz diorite in the Rio Icacos watershed (Luquillo Mountains, eastern Puerto Rico), was analyzed for major and trace element concentrations, Sr and Nd isotopic ratios and U-series nuclides (238U-234U-230Th-226Ra). In this profile a 40 cm thick soil horizon is overlying a 150 cm thick saprolite which is separated from the basal corestone by a ˜40 cm thick rindlet zone. The Sr and Nd isotopic variations along the whole profile imply that, in addition to geochemical fractionations associated to water-rock interactions, the geochemical budget of the profile is influenced by a significant accretion of atmospheric dusts. The mineralogical and geochemical variations along the profile also confirm that the weathering front does not progress continuously from the top to the base of the profile. The upper part of the profile is probably associated with a different weathering system (lateral weathering of upper corestones) than the lower part, which consists of the basal corestone, the associated rindlet system and the saprolite in contact with these rindlets. Consequently, the determination of weathering rates from 238U-234U-230Th-226Ra disequilibrium in a series of samples collected along a vertical depth profile can only be attempted for samples collected in the lower part of the profile, i.e. the rindlet zone and the lower saprolite. Similar propagation rates were derived for the rindlet system and the saprolite by using classical models involving loss and gain processes for all nuclides to interpret the variation of U-series nuclides in the rindlet-saprolite subsystem. The consistency of these weathering rates with average weathering and erosion rates derived via other methods for the whole watershed provides a new and independent argument that, in the Rio Icacos watershed, the weathering system has reached a geomorphologic steady-state. Our study also indicates that even in environments with differential

Longe de remeter a um processo homogêneo, a formação histórica desse grupo cobre um longo período temporal, envolvendo a interação de indivíduos provenientes de distin- tos grupos étnicos. A partir deste caso, objetiva-se fazer confluir a análise das estratégias acionadas pelos antecessores dessa comunidade para garantirem o acesso à terra em distintos contextos com dois conjuntos de discussões: aqueles suscitados pela historiografia brasileira acerca da escravidão e aqueles decorrentes da emergência de novos sujeitos de direito no Brasil, os remanescentes de quilombos.The text deals with the historical trajectory of the black rural community of Cambará, in Rio Grande do Sul, a state located in southern Brazil, which shares borders with Argentina and Uruguay and it is based upon written and oral sources Far from referring to a homogeneous process, the historical formation of this group covers a long period of time, involving the interaction of individuals from different ethnic groups. From this case, the objective is to conflate the analysis of strategies used by the predecessors of the community to ensure access to land in different contexts with two sets of discussions: those posed by the Brazilian historiography about slavery and those arising from the emergence of new subjects of rights in Brazil, the maroons - remanescents of quilombos.

    The Jandaira Formation (Turonian/Maastrichtian - Potiguar Basin, Brazil) presents an anomalous radioactive marker in the upper part of its carbonatic section. This marker of 3-20 m in thickness, comprises an area of about 3500 Km 2 and shows a radioactivity of 470 UAPI, against a background of 20 UAPI on the Gamma Ray Log. In the effort of characterizing this marker, petrological, mineralogical, geological and paleontological, analyses were made in ditch samples of selected 23 wells. This marker is composed by bioclastics packstones to mudstones, mainly constituted of planktonic and bentonic forams, deposited in relatively deep water. Chemical analysis of the P 205 richest samples, the ones show that they are also enriched on U, F, As, Cr, Cu, Mo, Ni, Pb, S, Se, V, Y, Yb and on all rare-earth elements. The origin of the radioactive anomaly is due to the presence of sedimentary phosphates (phosphorite) made-up of uraniferous coloform apatite. (author)

    Full Text Available ABSTRACT Loess consists of silt-dominated sediments that cover ~10% of the Earth's surface. In southern South America it occurs in Argentina, Bolivia, Paraguay and Uruguay, and its presence in southern Brazil was never studied in detail. Here is proposed a new lithostratigraphic unit, Cordão Formation, consisting of loess deposits in the southern Brazilian coastal plain. It consists of fine-very fine silt with subordinate sand and clay, found mostly in lowland areas between Pleistocene coastal barriers. These sediments are pale-colored (10YR hue and forms ~1,5-2,0 meter-thick stable vertical walls. The clay minerals include illite, smectite, interstratified illite/smectite and kaolinite, the coarser fraction is mostly quartz and plagioclase. Caliche and iron-manganese nodules are also present. The only fossils found so far are rodent teeth and a tooth of a camelid (Hemiauchenia paradoxa. Luminescence ages indicate that this loess was deposited in the latest Pleistocene, between ~30 and 10 kyrs ago, and its upper portion was modified by erosion and accumulation of clay and organic matter in the Holocene. The estimated accumulation rate was ~630 g/m2/year. The probable source of this loess is the Pampean Aeolian System of Argentina and it would have been deposited by the increased aeolian processes of the last glacial.

    Fluvial channel-fill deposits form highly heterogeneous hydrocarbon reservoirs. The study of outcrop analogs can help in the characterization of these heterogeneities, which are usually not detected by subsurface geophysical methods. The aim of this research is to compare outcrop log signatures with grain size trends and depositional elements of the fluvial deposits of the Late Permian Rio do Rasto Formation. A series of vertical gamma-ray logs were assembled in two outcrops in order to: 1) characterize log-facies in a succession composed of alternated flood plain, channel fill and eolian strata; 2) define within-channel spectral gamma-ray variability of a mixed-load composite point bar deposit and its relationship with grain size trends and lithofacies; 3) correlate log signatures observed in the outcrop sections with deep exploratory wells drilled several tens of kilometers from the study area. The results of this study show that gamma-ray logs have good correlation with grain size trends and that different depositional elements have distinct signatures. On the other hand, point bar deposits exhibit strong lateral changes in log signature due variations in grain size and mud content within lateral accretion strata. Although frequent, the classic bell-shaped log motif was not always detected, which means that the amount of fluvial channel-fill deposits recognized in subsurface can be underestimated. Similar log signatures were detected in the boreholes, at least in the closest ones, helping in paleoenvironmental interpretation in the subsurface. (author)

    Identification: A Study of Functions of Second Language in Enunciating Subject Constitution". Non-cognitive factors that have a crucial incidence in the degree of success and ways of accomplishment of second language acquisition process are focused. A transdisciplinary perspective is adopted, mobilising categories from Discourse Analysis and Psychoanalysis. The most relevant ones are: discursive formation, intradiscourse, interdiscourse, forgetting n° 1, forgetting n° 2 (Pêcheux, 1982, identity, identification (Freud, 1966; Lacan, 1977; Nasio, 1995. Revuz’s views (1991 are discussed. Her main claim is that during the process of learning a foreign language, the foundations of psychical structure, and consequently first language, are required. After examining how nomination and predication processes work in first and second languages, components of identity and identification processes are focused on, in an attempt to show how second language acquisition strategies depend on them. It is stated that methodological affairs of language teaching, learner’s explicit motivation and the like are subordinated to the comprehension of deeper non-cognitive factors that determine the accomplishment of the second language acquisition process. It is also pointed out that those factors are to be approached, questioning the bipolar biological-social conception of subjectivity in the study of language acquisition and use and including in the analysis symbolic and significant dimensions of the discourse constitution process.

The purpose of this study was: to define morphologically the contact between soil, saprolite and rock in Neossolos; generate data of the saprolite layer and test an inclusion in the suborder Neossolos Litólicos and Neossolos Regolíticos; and evaluate the diagnostic attributes and classes available in the Brazilian Soil Classification System for the of Neossolos Litólicos and Regolíticos derived from volcanic rocks of the Serra Geral formation in Rio Grande do Sul, State, Brazil. Five profiles of litho-climosequence were analyzed. The contacts were characterized based on the straight shovel excavation test associated to analyses of saprolite fracture and weathering classes. The contacts related to the presence of saprolite layers identified in the profile are not taken into consideration in the Brazilian Soil Classification System. Diagnostic attributes for the classification of Neossolos Regolíticos were proposed as well as a change of the term from "Regolítico" to "Saprolítico". New classes were also suggested for the third categorical level, based on information such as soil position and saprolite contact, excavation resistance and cracking level of the material. The proposed diagnostic attributes and classes allowed a more adequate classification of Neossolos derived from volcanic rocks in the State of Rio Grande do Sul.

    1985-01-01

    Sedimentological analyses of about 80 drill cores from the Charqueadas - Santa Rita Coal Field, west of Porto Alegre, Rio Grande do Sul State, were made. The Itarare Group is characterized by pelites of lacustrine origin and conglomerates and sandstones of alluvial fans, mainly in the north western region. A shallow lacustrine and paludal system characterize the Rio Bonito Formation, comprising coal seams and associated pelitic sediments, as well as some paraconglomerates and sandstone layers. The contact between these units is established by the colour of the pelites, differences in sedimentary textures, structures and palynological data. A marine transgression caused the sediments of the Rio Bonito Formation to be covered by coastal sandstones and pelites of the Palermo Formation, of tidal flat origin. Today, the coal layers and sediments have been eroded southward and slope gently to the north of the area.

  4. Project Rio Blanco: site restoration. Final report

    International Nuclear Information System (INIS)

    1978-01-01

    Project Rio Blanco was a joint Government-industry experiment using nuclear explosives to stimulate the flow of natural gas from low permeability formations which could not be economically produced through conventional methods. The project consisted of the simultaneous detonation of three nuclear explosives on May 17, 1973, in a 7,000 foot well in northwestern Colorado. Gas production testing and project evaluation continued through June 1976. The site cleanup and restoration planning phase began in December 1975 and was concluded with the issuance of an operational plan, Project Rio Blanco Site Cleanup and Restoration Plan, NVO-173, in May 1976. Actual site restoration activities were conducted during the period from July to November 1976. The activities throughout the restoration period are summarized and the final site status, including the disposition of all project facilities and the status of all project related wells after plug and abandonment and recompletion work are described

Cinco fases do processo de formação de caneluras puderam ser deduzidas pelas análises anatômicas. As primeiras alterações são representadas pelo aparecimento de células adensadas, hipertrofia e hiperplasia no parênquima e câmbio do floema e uma desorganização generalizada desta área. Segue-se uma atividade intensa do câmbio do floema adjacente e sua expansão em direção ao xilema. Esta invasão do xilema resulta na ruptura do anel do xilema pela massa celular do floema constituída de células recém formadas de parede celular delgada. Esta invasão do floema em direção ao xilema inicia um processo de degeneração dos vasos e parênquima do xilema. Finalmente há um colapso completo da região do xilema invadida, que é substituída pela massa do floema, resultando na canelura, notada ao se remover a casca.An ontogenetic study of the stem pitting was carried out, using as a model system the peduncle of flowers and fruits of sweet orange cv. Pêra infected by a very severe isolate, Capão Bonito, of Citrus tristeza virus (CTV. Anatomical and ultrastructural analysis revealed five phases of this process. It starts with the localized appearance of chromatic cells in the phloem parenchyma, hypertrophy of companion and cambial cells and overall disorganization of the phloem and deposition of a dense material. The next step is characterized by the invasion of the xylem by an abnormal mass of phloem parenchymal cells formed by the disorganized proliferation.

    1992-01-01

    The Secretary-General of the UN Conference on Environment and Development notes that after the Earth Summit in Rio de Janeiro discussions about the environment and development will differ from those prior to the Summit. These discussions must now incorporate problems of developing countries, poverty, inequalities, flow of resources to developing countries, and terms of trade. The Rio Declaration on Environment and Development consists of important tenets, but it must evolve into an Earth Charter to be endorsed on the 50th anniversary of the UN in 1965. The Summit's Plan of Action, Agenda 21, must also continue to evolve and, despite its shortcomings, is the most extensive and, if implemented, most effective international action ever approved by the international community. Financing the Agenda 21 initiatives remains to be decided. New possible sources of funding must be based n the polluter pays principle and may include new taxes, user charges, emission permits, and citizen funding. Even though the most serious problem in the 1990s is stabilization of atmospheric gases, the Rio agreement does not include targets or timetables. Governments must take united action immediately to reduce carbon dioxide emissions by at least 60%. 1 nation has not yet approved the convention on biological diversity. Governments also need to move forward on conventions on decertification and deforestation. They need to incorporate the global objectives of Agenda 21 into their own national policies and practices. This must also be done at the global, regional, organizational, local, and individual levels. The global community must also begin technology capacity building. The participatory process should also include nongovernmental organizations. Population growth must also slow dramatically to achieve sustainable development. The various participatory levels must consider elimination of poverty.

    Full Text Available The purpose of this article is to discuss the role of Rock in Rio: The Musical, as herald of megafestival Rock in Rio. Driven by the success that musicals have reached in Brazil, we believe that the design of this spectacle of music, dance and staging renews the brand of the rock festival, once it adds the force of young and healthy bodies to its concept. Moreover, the musical provides Rock in Rio with some distance from the controversal trilogy of sex, drugs and rock and roll, a strong mark of past festivals around the world. Thus, the musical expands the possibilities of growth for the brand.

    1992-01-01

    The June 1992 United Nations Conference on Environment and Development (UNCED) in Rio de Janeiro has been planned more as a discussion of environment and development, rather than sustainable development as suggested by the 1987 World Commission on Environment and Development (the Brundtland Commission). The Canadian agenda for UNCED is like that of most of the developed countries, and focuses mainly on climatic change, deforestation, loss of biodiversity in the tropics, and health of the oceans. The agenda of the developing countries is based on the knowledge that most of these global problems have been caused or aggravated by the industrialized countries. The developing countries fear that actions imposed to solve environmental problems will threaten their economic development. A key demand from the developing countries is a commitment by developed countries to reduce their greenhouse gas emissions, leaving space for the developing countries to increase their emissions as they develop. There is little or no pressure on governments in the developed world to come to such a comprehensive deal. For Canada, much remains to be done in setting national priorities, and many of the issues to be discussed at UNCED are under provincial jurisdiction

    Alldredge, A.W.; Whicker, F.W.; Hanson, W.C.

    Project Rio Blanco, an experiment involving deep underground detonation of three 30-kton nuclear explosives designed to stimulate natural gas flow in geologic formations of low permeability, was conducted in western Colorado on 17 May 1973. Environmental impacts associated with this experiment were divided into three categories: radiation, ground motion, and conventional physical activities. Radiation and ground motion are unique to this type experiment while conventional activities would be associated with any type of resource development. The objective of observations made at Rio Blanco was to qualitatively and, where possible, quantitatively ascertain environmental impacts associated with the project. Observations indicated that ground motion and conventional activities appeared to cause the greatest impacts. Ground motion impacts were most severe within 2.4 km of the emplacement well (EW) and were predominantly associated with steep ravine and stream banks and rocky cliffs. Following the detonation, flow and turbidity had increased in a small stream adjacent to the EW. Animals receiving deleterious impacts were those associated with stream banks, cliffs and burrows. No mortality or injury was observed in any large animals. (U.S.)

  17. Deforestation near Rio Branco, Brazil

    Science.gov (United States)

    2001-01-01

    Settlement and deforestation surrounding the Brazilian town of Rio Branco are seen here in the striking 'herring bone' deforestation patterns that cut through the rainforest. Rio Brancois the capital of the Brazilian state of Acre and is situated near the border with northeastern Bolivia. The town is a center for the distribution of goods, including rubber, metals, medicinal plants, Brazil nuts and timber. Colonization projects in the region are supported by farming, logging activities, and extensive cattle ranching. Much of the surrounding terrain is of a poorly-draining clay hardpan soil, and heavy rainfall periodically converts parts of the forested region to swamp.The large overview image was acquired by the Multi-angle Imaging SpectroRadiometer's vertical-viewing (nadir) camera on July 28, 2000, and covers an area of 336 kilometers x 333 kilometers. A plume of smoke is visible north of the Rio Branco road, which roughly parallels the slender, twisting Rio Abuna. Most of the major rivers in the image provide reference points for state or international (Bolivia-Brazil) boundaries, and flow northeast to the Rio Madeira (east of the smoke plume). The border between Acre and the Bolivian department of Pando is marked by the Rio Abuna. Pando's southern boundary with the department of Beni is marked by the Rio Madre de Dios, the large river in the lower half of the image.The two higher-resolution inset images highlight a settled area north of the town of Rio Branco. These nadir views cover an area of 60 kilometers x 67 kilometers, and were acquired eleven months apart during Terra orbits 3251 and 8144. In the later image, more haze is present, possibly due to smoke from fires on that day. Comparing the two images provides a method of measuring the changes and expansion in the area of cleared land. One newly cleared patch is apparent near the middle of the later image, slightly off to the right. This polygon represents an area of about 16 square kilometers, or 4000

    Woodruff, W.R.; Guido, R.S.

    1975-01-01

    Rio Blanco was the third experiment in the U.S. Atomic Energy Commission's Plowshare Program to develop technology to stimulate gas production from geologic formations not conducive to production by conventional means. The project was sponsored by CER Geonuclear Corporation, with the Lawrence Livermore Laboratory providing the explosives and several technical programs, such as spall measurement. Three nuclear explosives specifically designed for this application were detonated simultaneously in a minimum-diameter emplacement well using many commercially available but established-reliability components. The explosive system performed properly under extreme temperature and pressure conditions. Emplacement and stemming operations were designed with the aim of simplifying both the emplacement and reentry and fully containing the detonation products. An integrated command and control system was used with communication to all three explosives through a single coaxial cable. Reentry and the initial production testing are completed. To date 98 million standard ft 3 of chimney gas have been produced. (auth)

    The Rio Tinto, located in southwest Spain, exhibits a nearly constant, acidic pH-value along its course. Due to the formation of sulfate minerals, Rio Tinto is considered a potential analogue site for sulfate-rich regions on Mars, in particular at the landing site of the Mars Exploration Rover Opportunity, where the ferric sulfate mineral jarosite was identified with Opportunity's Moessbauer spectrometer. Primary and secondary mineralogy was investigated in situ with portable Raman and Moessbauer spectrometers at four different Rio Tinto sampling sites. The two techniques analyse different sample portions due to their specific field of view and sampling depth and provide complementary mineralogical information.

    GNSS navigation satellites are currently being developed by all major players in the science and technology scene, to compete with the GPS system. Because their applications span many different areas, from traffic and cargo control, to geodesy and seismic monitoring, it is required to assess the coherence between the different constellations. BDS is the GNSS system currently developed in China. Its first generation of satellites consisted of 3 geostationnary satellites allowing geolocalisation in China only. In addition to these satellites, other satellites have been launched in geostationnary and geosynchronous orbits, as well as satellites orbiting with a classical GNSS semi-major axis. With these additions, the BDS system possesses 19 operating satellites, and though the system is mostly efficient for geolocalisation in Asia, the satellites are also visible in other parts of the globe. In parallel to the development of the BDS constellation, China has launched the iGMAS (International GNSS Monitoring and Assessment Service) project to develop a global tracking network of multi-GNSS geodetic receivers. One of the goals of this project is to evaluate the efficiency of the BDS constellation as well as the efficiency of the receivers developed by the Chinese laboratories. As part of the Brazilian program COSBAN leaded by the Foreign Affairs Ministry to foster up the science and technology partnership with China, materialized by the collaboration between the Shanghai Astronomical Observatory/CAS and the Observatório Nacional/MCTI, in Rio de Janeiro. Through it the RIOS-iGMAS station was installed at Observatório Nacional, where the RJEP GNSS station already operates as part of the Brazilian reference system. Thus at the Observatório Nacional can be observed satellites from any constellation with both systems of reception, leading to a direct, efficient way to compare the results obtained for each network. In this communication we focus on the determination of the

    The upper Rio Hondo Basin occupies a drainage area of 585 square miles in south-central New Mexico and comprises three general hydrogeologic terranes: the higher elevation “Mountain Block,” the “Central Basin” piedmont area, and the lower elevation “Hondo Slope.” As many as 12 hydrostratigraphic units serve as aquifers locally and form a continuous aquifer on the regional scale. Streams and aquifers in the basin are closely interconnected, with numerous gaining and losing stream reaches across the study area. In general, the aquifers are characterized by low storage capacity and respond to short-term and long-term variations in recharge with marked water-level fluctuations on short (days to months) and long (decadal) time scales. Droughts and local groundwater withdrawals have caused marked water-table declines in some areas, whereas periodically heavy monsoons and snowmelt events have rapidly recharged aquifers in some areas. A regional-scale conceptual water budget was developed for the study area in order to gain a basic understanding of the magnitude of the various components of input, output, and change in storage. The primary input is watershed yield from the Mountain Block terrane, supplying about 38,200 to 42,300 acre-feet per year (acre-ft/yr) to the basin, as estimated by comparing the residual of precipitation and evapotranspiration with local streamgage data. Streamflow from the basin averaged about 21,200 acre-ft/yr, and groundwater output left the basin at an estimated 2,300 to 5,700 acre-ft/yr. The other major output (about 13,500 acre-ft/yr) was by public water supply, private water supply, livestock, commercial and industrial uses, and the Bonito Pipeline. The residual in the water budget, the difference between the totals of the input and output terms or the potential change in storage, ranged from -2,200 acre-ft/yr to +5,300 acre-ft/yr. There is a high degree of variability in precipitation and consequently in the water supply; small

  13. Rio Blanco massive hydraulic fracture: project definition

    International Nuclear Information System (INIS)

    1976-01-01

    A recent Federal Power Commission feasibility study assessed the possibility of economically producing gas from three Rocky Mountain basins. These basins have potentially productive horizons 2,000 to 4,000 feet thick containing an estimated total of 600 trillion cubic feet of gas in place. However, the producing sands are of such low permeability and heterogeneity that conventional methods have failed to develop these basins economically. The Natural Gas Technology Task Force, responsible for preparing the referenced feasibility study, determined that, if effective well stimulation methods for these basins can be developed, it might be possible to recover 40 to 50 percent of the gas in place. The Task Force pointed out two possible underground fracturing methods: Nuclear explosive fracturing, and massive hydraulic fracturing. They argued that once technical viability has been demonstrated, and with adequate economic incentives, there should be no reason why one or even both of these approaches could not be employed, thus making a major contribution toward correcting the energy deficiency of the Nation. A joint Government-industry demonstration program has been proposed to test the relative effectiveness of massive hydraulic fracturing of the same formation and producing horizons that were stimulated by the Rio Blanco nuclear project

    Perhaps the most published graphic in the oil industry is one that traces the price of oil through time. It is used as an overlay to correlate everything from the history of rig activity levels to predicting coming oil shortages and gluts. In Rio de Janeiro this month during the 17th World Petroleum Congress, Dr Don Paul of ChevronTexaco and Saudi Aramco's Abdulaziz Al-Kaabi used it to illustrate the role research and technology development must play within the oil industry. The author discusses the way the oil industry is spending money on research and development, he explains that in the past 20 years the biggest innovation in the industry has been 3D seismic. The critical strategy for oil business was the adaptation of 3D seismic from another industry which was then moulded for its own needs.

    Full Text Available The upper reaches of the Segre river, flowing through the Pyrenees, offers a variety of geomorphic surfaces that allow us to study soil chronosequences. The objective of this work is to widen the knowledge about the main characteristics and formation processes of some benchmark soils developed on fluvio-glacial, alluvial-fan and terrace materials of Pleistocene and Holocene age related to the Segre river, either siliceous or carbonatic. This knowledge will allow us to identify soil forming processes, commonly found in Mediterranean environments such as carbonate redistribution, clay formation and mobilization and rubefaction, all as functions of parent material and age. Five profiles, ranging from the Lower Pleistocene to the Holocene were classified according to Soil Taxonomy/WRB. The Montferrer profile (Calcic Palexeralf /Calcic Cutanic Luvisol (Chromic is a deep, partly decarbonated soil, with calcium carbonate accumulation in depth covering glacial features. The Torre del Remei profile (Typic Paleustalf /Cutanic Luvisol developed on silicic moraines and shows an extreme clay formation and illuviation. The Alp (Typic Haplustalf /Cutanic Luvisol and Tartera (Petric Calciustept /Petric Calcisol soils are developed on alluvial fans with calcium carbonate sources. The former is partly decarbonated, whilst the latter is rubefacted on top and shows speleothem-like carbonate pendants with superposition of clay illuviation. The youngest profile, Abellerols, (Typic Calciustept /Typic Calcisol shows only a partial decarbonation and calcite accumulation at depth. The results show that soil development is determined by the age of the surface and the source of calcite, either in the parent rock or brought by subsurface flow: clay illuviation is extreme in absence of it. Special morphologies of carbonate pendants are indicators of environmental conditions. The coexistence of clay coatings and secondary calcite can be explained by recarbonatation or by

    The Rio Maria Region, southeastern part of the Amazonian craton (Brazil), displays a typical Archaean granite-greenstone association intruded by Proterozoic granites. The greenstone is crosscut by Archaean granitoids, such as the Rio Maria granodiorite. Clear field contacts between the Xingu gneisses and the granodiorite are lacking, making it difficult to determine the stratigraphic sequence. U-Pb data for zircons from the Xingu gneiss and the Rio Maria granodiorite provide upper intercept ages of 2971 +30/ -28 Ma and 2874 +9/ -10 Ma respectively on the Concordia diagram. 2.97 Ga is the most ancient age ever obtained on zircons from gneisses of the Amazonian craton. It provides an upper limit for the beginning of the continental crust formation in this part of the craton. (author)

    Galaxy formation is at the forefront of observation and theory in cosmology. An improved understanding is essential for improving our knowledge both of the cosmological parameters, of the contents of the universe, and of our origins. In these lectures intended for graduate students, galaxy formation theory is reviewed and confronted with recent observational issues. In lecture 1, the following topics are presented: star formation considerations, including IMF, star formation efficiency and star formation rate, the origin of the galaxy luminosity function, and feedback in dwarf galaxies. In lecture 2, we describe formation of disks and massive spheroids, including the growth of supermassive black holes, negative feedback in spheroids, the AGN-star formation connection, star formation rates at high redshift and the baryon fraction in galaxies.

    Project Rio Blanco, an experiment involving deep underground detonation of three 30-kiloton nuclear explosives designed to stimulate natural gas flow in geologic formations of low permeability, was conducted in western Colorado on 17 May 1973. Environmental impacts associated with this experiment were divided into three categories: radiation, ground motion, and conventional physical activities. The objective of observations made at Rio Blanco was to qualitatively and, where possible, quantitatively ascertain environmental impacts associated with the project. Observations indicated that ground motion and conventional activities appeared to cause the greatest impacts. Ground motion impacts were most severe within 2.4 km of the emplacement well (EW) and were predominantly associated with steep ravine and stream banks and rocky cliffs. Following the detonation, flow and turbidity had increased in a small stream adjacent to the EW. Animals receiving deleterious impacts were those associated with stream banks, cliffs and burrows. No mortality or injury was observed in any large animals. Based on overall results it appears important to give adequate attention to environmental effects resulting from nuclear fracturing experiments

    This paper presents an updated overview integrating both previous and newly published data on the most important floras found associated with Early Permian coal seams in the Parana Basin, Brazil. These floras occur within the Rio Bonito Formation and correspond to the Gondwana ''Glossopteris Flora.'' For this review, five floras are selected, in ascending stratigraphic order: the ''Sao Joao do Triunfo,'' ''Figueira,'' ''Quiteria,'' ''Morro do Papaleo'' and ''Irapua Bed'' floras. They are the best-known floras of the basin in terms of taxonomic composition, paleoecology and environments of deposition. An early-mid Sakmarian to earliest Artinskian age is indicated for the Rio Bonito Formation based on absolute radiometric and relative biostratigraphic ages. Integration of available information about the selected floras allows evaluation of taphonomic and paleoecological factors to provide a more comprehensive understanding of the Early Permian floral record in the Parana Basin. The variation observed in both the taxonomic composition of individual floras and in the frequency of occurrence of different plant groups is due to the broad range of environmental/edaphic conditions that prevailed in the many different depositional settings represented in the Rio Bonito Formation. A more precise age determination obtained for the plant-bearing deposits permits the establishment of a more confident correlation between the Early Permian floral succession in the Parana Basin and other Early Permian floral successions in other basins. The Sakmarian global warming favored the appearance of pecopterid and sphenopterid ferns amongst the spore-producing plants, and the glossopterids amongst the pollen-producing plants. (author)

Fiel ao seu nome - homenagem a Haroldo de Campos, que, em poema homônimo, sinalizava para o conví­vio entre fronteiras -, a revista assumiu sua vocação transdisciplinar. O Programa de Estudos Pós-Graduados em Comunicação e Semiótica da PUC/SP confiou o projeto inicial do periódico a Irene Machado, que respondeu, de forma notável, pela editoria cientí­fica dos sete primeiros números. A dedicação de Irene Machado contribuiu para consolidar a proposta dos trânsitos e fluxos de idéias como fatores de fomento da diversidade que marca a Comunicação como campo cientí­fico. Sem esse competente trabalho, a revista não teria alcançado o significativo patamar Nacional A na escala de avaliação do sistema Qualis/CAPES.

    Full Text Available O magistério da Igreja tem a responsabilidade de ensinar e zelar pelo bem dos membros da comunidade eclesial. No campo da teologia moral, historicamente tem havido tensões e dissensos entre a autoridade eclesiástica e teólogos e cristãos que desejam se explicitem as razões das normas que lhe são impostas. Posições diversas sobre que esta questão mostram, entre outras urgências, a necessidade de se passar da submissão à palavra da autoridade, por medo, para a autonomia respeitosa que inclui a racionalidade das normas morais. Do contrário, se caminharia para a formação de uma consciência autoritária. Na busca de crescimento nessas relações os cristãos que ousam manifestar seu dissentimento ante o magistério contribuem para o avanço da formulação da doutrina moral católica. No processo vital da experiência eclesial, as tensões nascidas do esforço do desejo de compreensão racional da moral podem ajudar tanto o magistério quanto os teólogos no exercício das respectivas funções, por meio do diálogo verdadeiro. ABSTRACT: The Magisterium of the Church has a responsibility to teach and care for the good of the members of the Church community. In the field of moral theology, historically there has been tension and dissent among the ecclesiastical authority and theologians and Christians who want to more clearly define the reasons of the standards that are imposed. Diverse positions on this issue show, among other urgencies, the need to move from the submission to the word of authority, out of fear, to respectful autonomy that includes the rationality of moral norms. Otherwise, the tendency would be toward the formation of an authoritarian consciousness. In search of growth in these relationships the Christians who dare to express their voice against teaching contribute to the advancement of formulation of Catholic moral doctrine. In the vital process of ecclesial experience, the tensions born of the effort in the desire

    Through the experiences of two West Africans shipped to Bahia as slaves, probably in the 1840s, then sold south to Rio de Janeiro where they met, became lovers, bought their freedom, married, and divorced, I comment on an ongoing debate over the refashioning or transfer of African ethnic identities in American slave societies. The sources in this Brazilian case suggest that previous identities were not suddenly erased, but rather, new layers of understanding and ways of responding were added. Whatever the dynamic of cultural formation, it was memory that crucially bridged the distance between the past they carried with them and the present into which they were thrust; and so it becomes illuminating to reconstruct the plausibly remembered African pasts on which this couple drew to make sense of an unfamiliar Brazilian present.

    Petroleum plant activities in the Amazon result in a series of negative impacts on the natural resources. The formation water, a secondary product of oil production, carries high salt levels and its environmental release results in salinization of several water bodies in the Amazon. The effect of formation water on vegetal and animal physiology is unknown. This paper estimated the effects of formation water from the Urucu petroleum plant at different dilutions on the haematocrit, hemoglobin concentration, red blood cell counts, mean corpuscular volume, mean hemoglobin concentration, mean corpuscular hemoglobin concentration, blood oxygen content, partial pressure of oxygen, glucose and lactate levels, plasma and intra erythrocytic levels of Na{sup +}, K{sup +} and Ca{sup 2+}, Phe and p Hi of Colossoma macropomum (Branchial breather) and Glyptoperichthys joselimaianus (facultative air breather). To maintain tissue oxygen supply the studied species adjusted several of these parameters. Cell swelling, high lactate levels, decrease in p He and p Hi have been observed in G. joselimaianus exposed to formation water. The decrease in p Hi result in a decrease of Hb-O{sub 2} affinity in the erythrocytes. On the other hand, an increase in p He and p Hi were observed in C. macropomum. Significant changes in ionic content, in particular plasma and erythrocytic levels of sodium, have been observed for both species exposed to formation water. A decrease of plasma potassium was observed in G. joselimaianus. The intra erythrocytic levels of calcium increased in Colossoma and Glyptoperichthys but no significant change in plasma levels of calcium was observed. The disturbance in blood ion levels resulted in a decreased of blood oxygen content. Colossoma seems to better buffer the effects of formation water exposure than Glyptoperichthys. (author)

E-mail: ummaia@usp.br This study aimed to assess the current status of stingless bee beekeeping (meliponiculture in the State of Rio Grande do Norte, Brazil, with the aid of structured questionnaires made during visits to beekeepers. The results were compared with a previous census made in the state and with a similar study from Australia. Meliponiculture in Rio Grande do Norte is still informal and little standardized. The activity has grown in recent years considering the mean number of nests per beekeeper. Most apiaries are formed of up to 50 colonies, usually distributed in the backyards of homes. Twelve species of stingless bees were reared in the state, and the most common was the “Jandaíra” bee (Melipona subnitida, whose honey is considered medicinal. While many beekeepers already know the importance of bees as pollinators, stingless bees are still not used for crop pollination. Compared to a recent analysis of beekeeping in Australia, meliponiculture in Brazil is more traditional, honey is the main product and the number of colonies per beekeeper is much higher. Our results highlight the need to reinforce knowledge about bees and promote specific training aimed at improving and standardizing management practices.

    Samples of ''sandstone'' from near the site of the upper Rio Blanco nuclear explosion were heated in the laboratory at temperatures between 600 and 900 0 C. The composition and amount of noncondensable (dry) gas released were measured and compared to the amount and composition of gas found underground following the explosion. The gas released from the rock heated in the laboratory contained approximately 80 percent CO 2 and 10 percent H 2 ; the balance was CO and CH 4 . With increasing temperature, the amounts of CO 2 , CO, and H 2 released increased. The composition of gas released by heating Rio Blanco rock in the laboratory is similar to the composition of gas found after the nuclear explosion except that it contains less natural gas (CH 4 , C 2 H 6 . . .). The amount of noncondensable gas released by heating the rock increases from approximately 0.1 mole/kg of rock at 600 0 C to 0.9 mole/kg at 900 0 C. Over 90 percent of the volatile components of the rock are released in less than 10 h at 900 0 C. A comparison of the amount of gas released by heating rock in the laboratory to the amount of gas released by the heat of the Rio Blanco nuclear explosion suggests that the explosion released the volatile material from about 0.42 mg of rock per joule of explosive energy (1700 to 1800 tonnes per kt).

    The Rio Grande Gorge is a 115 km long river canyon located in Southern Colorado (15 km) and Northern New Mexico (100 km). The majority of the canyon is under the administration of the Bureau of Land Management {BLM), and 77 km of the canyon south of the Colorado/New Mexico border are designated Wild River under the National Wild and Scenic Rivers Act of 1968. Visits I have made to the Rio Grande Gorge over the past 15 .years disclosed some raptor utilization. As the Snake River Birds of Prey Natural Area gained publicity, its similarity to the Rio Grande Gorge became obvious, and I was intrigued by the possibility of a high raptor nesting density in the Gorge. A survey in 1979 of 20 km of the northern end of the canyon revealed a moderately high density of red-tailed hawks and prairie falcons. With the encouragement of that partial survey, and a need to assess the impact of river-running on nesting birds of prey, I made a more comprehensive survey in 1980. The results of my surveys, along with those of a 1978 helicopter survey by the BLM, are presented in this report, as well as general characterization of the area, winter use by raptors, and an assessment of factors influencing the raptor population.

    Full Text Available The 1992 Rio Earth Summit was of paramount importance in the consolidation and international dissemination of environmental impact assessment, officially recognized as a tool for informed decision-making towards sustainable development (Principle 17, Rio Declaration and for protection of biodiversity (Article 14, Convention on Biological Diversity. A significant development afterwards was the strengthening of strategic environmental assessment in the design of policies, plans and programs. Both forms of impact assessment can establish the necessary connections between one goal of the Rio+20 Conference - reaching an agreement on the transition to a green economy - and the underpinning decision making processes. Although the Rio+20 Summit has faced challenges to acknowledge its potential, impact assessment should be strengthened in support of both government and business decisions.La Cumbre de la Tierra de 1992 fue de la más grande importancia en la consolidación y diseminación de la evaluación de impacto ambiental, oficialmente reconocida como una herramienta para la toma de decisiones informada hacia el desarrollo sostenible (Principio 17, Declaración de Rio y para la protección de la biodiversidad (Artículo 14, Convención de la Diversidad Biológica. Un avanzo posterior importante fue el fortalecimiento de la evaluación ambiental estratégica en la preparación de políticas, planos y programas. Ambas formas de evaluación de impacto son capaces de establecer los necesarios vínculos entre un objetivo declarado de la Conferencia Rio+2- - llegar a un acuerdo sobre la transición para una economía verde - y los procesos decisorios subyacentes. Aunque la Cumbre Rio+20 tenga encontrado dificultades en reconocer su potencial, la evaluación de impactos debería ser fortalecida en soporte de decisiones gubernamentales y privadas.A Cúpula da Terra de 1992, no Rio de Janeiro, teve a maior importância na consolidação e dissemina

    Theoretical models of star formation are discussed beginning with the earliest stages and ending in the formation of rotating, self-gravitating disks or rings. First a model of the implosion of very diffuse gas clouds is presented which relies upon a shock at the edge of a galactic spiral arm to drive the implosion. Second, models are presented for the formation of a second generation of massive stars in such a cloud once a first generation has formed. These models rely on the ionizing radiation from massive stars or on the supernova shocks produced when these stars explode. Finally, calculations of the gravitational collapse of rotating clouds are discussed with special focus on the question of whether rotating disks or rings are the result of such a collapse. 65 references

  3. Comet formation

    There has been vast progress in our understanding of planetesimal formation over the past decades, owing to a number of laboratory experiments as well as to refined models of dust and ice agglomeration in protoplanetary disks. Coagulation rapidly forms cm-sized ''pebbles'' by direct sticking in collisions at low velocities (Güttler et al. 2010; Zsom et al. 2010). For the further growth, two model approaches are currently being discussed: (1) Local concentration of pebbles in nebular instabilities until gravitational instability occurs (Johansen et al. 2007). (2) A competition between fragmentation and mass transfer in collisions among the dusty bodies, in which a few ''lucky winners'' make it to planetesimal sizes (Windmark et al. 2012a,b; Garaud et al. 2013). Predictions of the physical properties of the resulting bodies in both models allow a distinction of the two formation scenarios of planetesimals. In particular, the tensile strength (i.e, the inner cohesion) of the planetesimals differ widely between the two models (Skorov & Blum 2012; Blum et al. 2014). While model (1) predicts tensile strengths on the order of ˜ 1 Pa, model (2) results in rather compactified dusty bodies with tensile strengths in the kPa regime. If comets are km-sized survivors of the planetesimal-formation era, they should in principle hold the secret of their formation process. Water ice is the prime volatile responsible for the activity of comets. Thermophysical models of the heat and mass transport close to the comet-nucleus surface predict water-ice sublimation temperatures that relate to maximum sublimation pressures well below the kPa regime predicted for formation scenario (2). Model (1), however, is in agreement with the observed dust and gas activity of comets. Thus, a formation scenario for cometesimals involving gravitational instability is favored (Blum et al. 2014).

    Full Text Available Aplicação da tecnologia na agricultura dentro do sistema de produção é realidade principalmente com a abertura de mercados através da globalização. Em diversas áreas da indústria moderna, o calcário é utilizado como corretor da acidez do solo. A calagem é uma prática barata, porém ainda é negligenciada quanto ao seu uso, na adoção da técnica, à definição das doses e às formas de aplicação. A briquetagem consiste na aglomeração de partículas finas através de pressão, auxiliada ou não por aglomerantes, permitindo obtenção de produtos compactados, com forma, tamanho e parâmetros mecânicos adequados. A redução de volume do material, além dos benefícios tecnológicos, permite que materiais finos possam ser transportados e armazenados de forma mais econômica. A recente preocupação ambiental, resultando em leis mais rígidas, além da necessidade de aproveitar economicamente os resíduos e as partículas finas geradas no beneficiamento de minérios fez com que a briquetagem voltasse a ser uma importante alternativa para aglomerar valor econômico. O objetivo deste trabalho foi aglomerar finos de calcário através da briquetagem (92% abaixo de 500# ou 25 µm gerados no processamento do mesmo, variando as dosagens de água (utilizada como agente aglomerante de 0; 5; 7,5; 10; 12,5 e 15%. O calcário, originário de Lagamar (MG, foi classificado quimicamente como dolomítico tipo D. Os briquetes foram submetidos a testes de queda a 30, 60, 90, 120 e 150 cm de altura. Os melhores resultados encontrados para ensaios de queda foram obtidos com 7,5% de umidade, com médias de 21 quedas para 30 cm e 10 quedas para 60 cm de altura. Tais resultados apresentaram-se favoráveis quando comparados à literatura, a qual cita que para briquetes sem cura, considera-se 3 quedas a 0,3 m como valor razoável.

    Twenty-seven springs discharge from the Totavi Lentil and Tesuque Formation in White Rock Canyon. Water generally acquires its chemical characteristics from rock units that comprise the spring aquifer. Twenty-two of the springs are separated into three groups of similar aquifer-related chemical quality. The five remaining springs make up a fourth group with a chemical quality that differs due to localized conditions in the aquifer. Localized conditions may be related to recharge or discharge in or near basalt intrusion or through faults. Streams from Pajarito, Ancho, and Frijoles Canyons discharge into the Rio Grande in White Rock Canyon. The base flow in the streams is from springs. Sanitary effluent in Mortandad Canyon from the treatment plant at White Rock also reaches the Rio Grande

    Full Text Available This work focuses on Neoproterozoic supracrustal rocks related to Andrelandia megasequence, which are superimposed on the basis represented by neoarchean granulites and palaeoproterozoic ortogneiss, in order to define palaeoenvironments of deposition of metasedimentary rocks and typological model of zinc mineralization of Rio Claro, Rio de Janeiro State, SE of Brazil. Three stratigraphic units in the area were considered for the studies: Valadão, São Roque and Lidice. Valadão unit was divided into three subunits: psamitic, psamitic / pelitic and pelitic. On the whole, it represents a turbiditic sequence influenced by underwater hydrothermal exhalations that led to the formation of quartzite with magnetite, considered as banded iron formations. São Roque Unit is composed of four subunits (São Roque I, II, III and IV and presents a typical pattern of deposition of low energy environments, in marine deep basins. Gondite, coticules levels and (Mn-almandine present in the local gneiss mark the manganese exalative contribution in that unit. Lídice unit has different sedimentation palaeoenvironments and is subdivided into Lídice I, II and III. Lídice subunits I and II exhibit quartzite interleaved with pelitic rocks and graphite gneiss, suggesting deposition in deeper environments of the basin, probably related to turbidity currents. In Lídice III subunit, more carbonated and with more quartz, limestone quartzite stand out, which enclose mineralized zones, reflecting depositional environment in shallow platform, possibly involving evaporitic environment, sabkha type. Sulfite mineralization of Rio Claro, associated with platformal rocks intensely metamorphosed and deformed, as well as its local geological context, features similarities with sedimentary exhalative deposits (SEDEX Zn-Pb-Ag model, Shuswap and Monashee type, present in Monashee and Shuswap Complexes of British Columbia in Canada.

    Updated age assignments and new collections of molluscan fossils from lower Cenomanian through upper Campanian strata in Texas permit a much refined biostratigraphic correlation with the rocks of New Mexico and the Western Interior. Generic names of many Late Cretaceous ammonites and inoceramid bivalves from Texas are updated to permit this correlation. Strata correlated in the west-to-east transect include the lower Cenomanian Beartooth Quartzite and Sarten Sandstone of southwest New Mexico, and the Eagle Mountains Formation, Del Rio Clay, Buda Limestone, and. basal beds of the Chispa Summit, Ojinaga, and Boquillas Formations of the Texas-Mexico border area. Middle Cenomanian strata are lacking in southwestern New Mexico but are present in the lower parts of the Chispa Summit and Boquillas Formations in southwest Texas. Upper Cenomanian and lower Turonian rocks are present at many localities in New Mexico and Texas in the Mancos Shale and Chispa Summit, Ojinaga, and Boquillas Formations. Middle Turonian and younger rocks seem to be entirely nonmarine in southwestern New Mexico, but they are marine in the Rio Grande area in the Chispa. Summit, Ojinaga, and Boquillas Formations. The upper part of the Chispa Summit and Boquillas contain late Turonian fossils. Rocks of Coniacian and Santonian age are present high in the Chispa Summit, Ojinaga, and Boquillas Formations, and in the lower part of the Austin. The San Carlos, Aguja, Pen, and Austin Formations contain fossils of Campanian age. Fossils representing at least 38 Upper Cretaceous ammonite zones are present along the transect. Collections made in recent years in southwestern New Mexico and at Sierra de Cristo Rey just west of downtown El Paso, Texas, have been well treated and do not need revision. Taxonomic names and zonations published in the pre-1970 literature on the Rio Grande area of Texas have been updated. New fossil collections from the Big Bend National Park, Texas, allow for a much refined correlation

  18. Planet Formation

    Science.gov (United States)

    Podolak, Morris

    2018-04-01

    Modern observational techniques are still not powerful enough to directly view planet formation, and so it is necessary to rely on theory. However, observations do give two important clues to the formation process. The first is that the most primitive form of material in interstellar space exists as a dilute gas. Some of this gas is unstable against gravitational collapse, and begins to contract. Because the angular momentum of the gas is not zero, it contracts along the spin axis, but remains extended in the plane perpendicular to that axis, so that a disk is formed. Viscous processes in the disk carry most of the mass into the center where a star eventually forms. In the process, almost as a by-product, a planetary system is formed as well. The second clue is the time required. Young stars are indeed observed to have gas disks, composed mostly of hydrogen and helium, surrounding them, and observations tell us that these disks dissipate after about 5 to 10 million years. If planets like Jupiter and Saturn, which are very rich in hydrogen and helium, are to form in such a disk, they must accrete their gas within 5 million years of the time of the formation of the disk. Any formation scenario one proposes must produce Jupiter in that time, although the terrestrial planets, which don't contain significant amounts of hydrogen and helium, could have taken longer to build. Modern estimates for the formation time of the Earth are of the order of 100 million years. To date there are two main candidate theories for producing Jupiter-like planets. The core accretion (CA) scenario supposes that any solid materials in the disk slowly coagulate into protoplanetary cores with progressively larger masses. If the core remains small enough it won't have a strong enough gravitational force to attract gas from the surrounding disk, and the result will be a terrestrial planet. If the core grows large enough (of the order of ten Earth masses), and the disk has not yet dissipated, then

    The San Luis Basin encompasses the largest structural and hydrologic basin of the Rio Grande rift. On this field trip, we will examine the timing of transition of the San Luis Basin from hydrologically closed, aggrading subbasins to a continuous fluvial system that eroded the basin, formed the Rio Grande gorge, and ultimately, integrated the Rio Grande from Colorado to the Gulf of Mexico. Waning Pleistocene neotectonic activity and onset of major glacial episodes, in particular Marine Isotope Stages 11–2 (~420–14 ka), induced basin fill, spillover, and erosion of the southern San Luis Basin. The combined use of new geologic mapping, fluvial geomorphology, reinterpreted surficial geology of the Taos Plateau, pedogenic relative dating studies, 3He surface exposure dating of basalts, and U-series dating of pedogenic carbonate supports a sequence of events wherein pluvial Lake Alamosa in the northern San Luis Basin overflowed, and began to drain to the south across the closed Sunshine Valley–Costilla Plain region ≤400 ka. By ~200 ka, erosion had cut through topographic highs at Ute Mountain and the Red River fault zone, and began deep-canyon incision across the southern San Luis Basin. Previous studies indicate that prior to 200 ka, the present Rio Grande terminated into a large bolson complex in the vicinity of El Paso, Texas, and systematic, headward erosional processes had subtly integrated discontinuously connected basins along the eastern flank of the Rio Grande rift and southern Rocky Mountains. We propose that the integration of the entire San Luis Basin into the Rio Grande drainage system (~400–200 ka) was the critical event in the formation of the modern Rio Grande, integrating hinterland basins of the Rio Grande rift from El Paso, Texas, north to the San Luis Basin with the Gulf of Mexico. This event dramatically affected basins southeast of El Paso, Texas, across the Chisos Mountains and southeastern Basin and Range province, including the Rio

    This second edition of Galaxy Formation is an up-to-date text on astrophysical cosmology, expounding the structure of the classical cosmological models from a contemporary viewpoint. This forms the background to a detailed study of the origin of structure and galaxies in the Universe. The derivations of many of the most important results are derived by simple physical arguments which illuminate the results of more advanced treatments. A very wide range of observational data is brought to bear upon these problems, including the most recent results from WMAP, the Hubble Space Telescope, galaxy surveys like the Sloan Digital Sky Survey and the 2dF Galaxy Redshift Survey, studies of Type 1a supernovae, and many other observations.

    The current debate on the origin and evolution of galaxies is reviewed and evidence to support the so-called 'isothermal' and 'adiabatic' fluctuation models considered. It is shown that new theories have to explain the formation of both spiral and elliptical galaxies and the reason for their differences. It is stated that of the most recent models the best indicates that rotating spiral galaxies are formed naturally when gas concentrates in the centre of a great halo and forms stars while ellipticals are explained by later interactions between spiral galaxies and merging, which can cancel out the rotation while producing an elliptical galaxy in which the stars, coming from two original galaxies, follow very elliptical, anisotropic orbits.

  8. Habit formation.

    Smith, Kyle S; Graybiel, Ann M

    2016-03-01

    Habits, both good ones and bad ones, are pervasive in animal behavior. Important frameworks have been developed to understand habits through psychological and neurobiological studies. This work has given us a rich understanding of brain networks that promote habits, and has also helped us to understand what constitutes a habitual behavior as opposed to a behavior that is more flexible and prospective. Mounting evidence from studies using neural recording methods suggests that habit formation is not a simple process. We review this evidence and take the position that habits could be sculpted from multiple dissociable changes in neural activity. These changes occur across multiple brain regions and even within single brain regions. This strategy of classifying components of a habit based on different brain signals provides a potentially useful new way to conceive of disorders that involve overly fixed behaviors as arising from different potential dysfunctions within the brain's habit network.

The article classifies medical slang in three broad areas, pertaining to the physician's relations with professional training and knowledge, patients, and health care services. Comparing his empirical material with previous studies focusing on hospital slang for patients, the author identifies, in addition, a range of slang terms for health care services themselves. The article points to interfaces between medical slang and the Brazilian "health hypercrisis" identified by Schramm.

    2002-01-01

    Few data are available on the dynamic of radon in the air for tropical climate conditions. The strong influence of the climatological characteristics on the transport of gases and particulates in air makes not adequate the use of data obtained at regions with different climate. Outdoor and indoor measurements of radon equilibrium equivalent concentrations (EEC) have been done for one-year period in Rio de Janeiro. Continuous measurements were performed using a radon monitor with an alpha spectrometry detector. Pluviometric index, temperature and humidity were registered. The paper presents the long term behaviour of outdoor radon equilibrium equivalent concentration results, their correlation with temperature and the influence of the pluviometric index. Maximum values were obtained during winter and minimum in summer, strongly influenced by the rain. A strong inverse correlation with temperature was found. (author)

    2010-06-01

    Full Text Available A reference inventory of prehistoric marine mollusks from the Rio das Ostras region was created based on an excavation carried out at the Sambaqui da Tarioba shellmound. Patterns of richness and biogeography were studied, and the representativeness of bivalve and gastropod diversities found at this archaeological site were inferred. A total of 47 taxa belonging to 28 families, most of which from unconsolidated substrates, was identified. The shellmound species composition does not differ from the present-day composition. All recorded species are characteristic of a wide transition zone between the south of the states of Espírito Santo (21°S and Rio Grande do Sul (32°S. Thus, the data show little evidence of evolution in the composition, richness,and biodiversity distribution patterns of mollusks in the Rio das Ostras region. Likewise, a reconstitution of the paleoenvironment from the functional characteristics of the shellmound species indicates that the locality's geomorphology and climate remained largely unchanged in the last 4,000 years BP.

    applied to a graduate program in Management, and data gathering was made through a single enquiry about the meaning attributed by graduate students to the development of the apprenticeship period. Content analysis was used to allow interpretation of the data collected. Through the perceptions of graduate students, the contributions, meaning and motivations to conduct teaching apprenticeship periods were highlighted. In so doing, it was possible to identify the need to adapt the discipline in practical terms so as to stimulate greater engagement of all agents, and in order that results produced collectively be better and more effective. Lastly, it was possible to observe that the process of the formation of teachers in stricto sensu graduate programs requires a (reintegration between theory and practice so that engaging in teaching apprenticeship can be an interesting way to promote the practice of teaching by graduate students. Additionally, for those more involved with research and with the technical reading of academic texts a higher motivation mentioned was the reduction of the distance experienced between theory and practice.

    Full Text Available Neste artigo consideramos os problemas ambientais globais dentro do conceito de limiares planetários, em convergência com os últimos avanços das ciências naturais. Nesse contexto, nosso objetivo é explorar o papel do Brasil na governança do espaço de operação seguro para a humanidade, avaliando como o país complementa o enorme capital ambiental físico que possui com ações políticas específicas orientadas para uma economia verde de baixo carbono (EVBC, tanto no âmbito doméstico quanto no internacional. Para atingir essa meta, em primeiro lugar discutimos conceitualmente a economia verde de baixo carbono como paradigma de desenvolvimento compatível com um espaço de operação seguro para a humanidade; em segundo lugar, analisamos a Rio+20 pelo prisma da governança global dos limiares planetários e pela atuação brasileira na Cúpula; e finalmente fazemos um diagnóstico da situação do Brasil em relação ao novo paradigma de desenvolvimento. Como conclusões da análise, destacamos a crescente distância entre a aceleração dos problemas da interdependência - especialmente a definição de um espaço seguro de operação para a humanidade - e os mecanismos globais de governança existentes, derivada de um sistema internacional bloqueado e dominado por forças conservadoras. O resultado frustrante da Rio+20 é evidência clara dessa defasagem. Nessa dinâmica, o Brasil tem o potencial para ser um ator central da governança dos limiares planetários, por seu vasto capital ambiental físico. No entanto, o mínimo avanço da EVBC no país degrada essa capacidade de agência, e o torna uma potência ambiental subdesenvolvida (underachiever environmental power.

Através de fontes primárias e análise documental, a pesquisa desenvolve interpretações sobre as influências paternas de caráter moral, cultural, intelectual e profissional que marcaram a primeira geração da família Palmério no Brasil e, particularmente, condicionaram as experiências que mais tarde seriam ressignificadas na obra literária e na trajetória pessoal de Mário Palmério. Notamos que as permanentes viagens a trabalho do pai e as suas diversas atividades profissionais favoreceram uma consciência familiar das particularidades da região. Essa experiência favoreceu a criação de vínculos econômicos, políticos e afetivos com a cultura regional e estimulou nos filhos um profundo conhecimento histórico e geográfico do Oeste mineiro. Além disso, o pai parece ter exercido uma profunda influência sobre os filhos no que diz respeito ao gosto pela política regional.

    Full Text Available Este estudo defende que o comportamento aleatório pode tornar-se legítimo objeto de estudo de uma ciência do comportamento. Analisamos inicialmente algumas considerações que B. F. Skinner formulou sobre o comportamento aleatório em suas Contingências do Reforço. Segundo Skinner (1969/1975, o comportamento aleatório "não apresenta interesse como processo de comportamento". Apresentamos uma rigorosa definição de "comportamento aleatório". Sustentamos que o comportamento aleatório pode constituir objeto de análise funcional, examinando alguns estudos empíricos que se têm conduzido sobre o comportamento aleatório. Apresentamos ainda algumas dificuldades empíricas e teóricas que podem afetar as investigações nessa área. Concluímos que o comportamento aleatório é um fascinante e importante tópico para uma completa ciência do comportamento.

    In order to study the groundwater dynamics of the Northwest of the Entre Rios Province (Republica Argentina), supported on the regional knowledge resulting from previous reports, a detailed investigation is developed. The most important aquifer of the region, conformed by sands of the Ituzaingo and Parana Formations (Mioceno-Plioceno) underlies Hernandarias Formation (Pleistoceno) thick clays cover. This confinement condition, and the complex hydrodynamic behaviour as a result of the heterogeneity of the hydrogeological sequence, impeded determine with clearness the existence of actual and direct connections with the exterior cycle. The application of classical geohydrochemical methodologies complemented with both isotopic and heavy metals measurements, and data geostatistical processing, allows to formulate hypothesis about groundwater origin and the incidence of the autochthonous recharge.

    1992-10-01

    In reviewing the work packages included in the Rio Earth's Summit Agenda 21, intended as an activities guideline for international cooperation to ensure environmental protection with sustainable growth for all nations, this paper points out the areas which present the greatest obstacles in the establishment of common accords and discusses the directions being taken to surmount these obstacles. A major obstacle concerns uncertaindes in specifying limits on carbon dioxide emissions and their effects on world climate. Another concerns suitable methods to help finance effective technology transfer to developing countries. With regard to the former problem, a 'no regret' approach has been proposed to limit current C02 reduction interventions to those levels which, in all certainty, would not incur any future regrets once scientific knowledge has advanced enough to allow more accurate assessments of greenhouse gas/climate change inter-relationships. With regard to the latter problem, attempts are being made to reduce possible negative impacts on the petroleum industry due to energy surcharges suggested as a source of funding for technology transfer/environmental protection programs.

    Antioxidant fractions from two different citrus species such as Rio Red (Citrus paradise Macf.) and Sour orange (Citrus aurantium L.) were extracted with five different polar solvents using Soxhlet type extractor. The total phenolic content of the extracts was determined by Folin-Ciocalteu method. Ethyl acetate extract of Rio Red and Sour orange was found to contain maximum phenolics. The dried fractions were screened for their antioxidant activity potential using in vitro model systems such as 1,1-diphenyl-2-picryl hydrazyl (DPPH), phosphomolybdenum method and nitroblue tetrazolium (NBT) reduction at different concentrations. The methanol:water (80:20) fraction of Rio Red showed the highest radical scavenging activity 42.5%, 77.8% and 92.1% at 250, 500 and 1000 ppm, respectively, while methanol:water (80:20) fraction of Sour orange showed the lowest radical scavenging activity at all the tested concentrations. All citrus fractions showed good antioxidant capacity by the formation of phosphomolybdenum complex at 200 ppm. In addition, superoxide radical scavenging activity was assayed using non-enzymatic (NADH/phenaxine methosulfate) superoxide generating system. All the extracts showed variable superoxide radical scavenging activity. Moreover, methanol:water (80:20) extract of Rio Red and methanol extract of Sour orange exhibited marked reducing power in potassium ferricyanide reduction method. The data obtained using above in vitro models clearly establish the antioxidant potential of citrus fruit extracts. However, comprehensive studies need to be conducted to ascertain the in vivo bioavailability, safety and efficacy of such extracts in experimental animals. To the best of our knowledge, this is the first report on antioxidant activity of different polar extracts from Rio Red and Sour oranges.

    1977-01-01

    Determination of the carbon and oxygen isotopic compositions were made on approximately 100 samples of Late Precambrian metasedimentary rocks of the Rio Pardo Group from Southern Bahia. The results obtained show that carbon varies from δ 13 =C=5,73 per mille to δ 13 C=+9,00 per mille, and oxygen from δ 18 O=-1,87 per mille to δ 18 O=-19,67 per mille relative to PBD. The interpretations lead to some conclusions which confirm the validity the isotopic technique as auxiliary instrument in the study of geological problems. These include: 1) the evidence of a marine transgression during the Camaca sedimentation; 2) the probability that the dolomitic metalimestones of the Agua Preta formation belong to the Serra do Paraiso formation; 3) the assignment of the dolomitic metalismestones, which occur in Itiroro and which had been previously grouped with the crystalline basement rocks, to the Serra do Paraiso formation; 4) the removal of the marble from Serra do Paraiso formation and re-signment to the basement rocks, and finally; 5) the sedimentary evolution of the Rio Pardo Group from a typical fresh-water to a marine environment.

Os animais afetados eram, normalmente, encontrados mortos ou apresentavam evolução aguda de 2 a 3 horas com acentuada depressão, cólicas abdominais e diarréia profusa com fibrina. Em duas propriedades relataram-se casos com a evolução de até 12 horas. Em treze animais necropsiados observaram-se aumento de líquidos nas cavidades abdominal, torácica e pericárdica, congestão e hiperemia da serosa e mucosa do intestino, conteúdo do cólon líquido com fibrina além de hemorragias de serosa e fibrina. Em um animal constatou-se microangiopatia cerebral caracterizada por acúmulo de material homogêneo e eosinofílico no espaço perivascular. No conteúdo intestinal, colônias com bastonetes morfológica e bioquimicamente sugestivos de Clostridium perfringens foram caracterizadas no estudo bacteriológico. A soroneutralização em camundongos com conteúdo intestinal dos animais afetados, revelou a presença da toxina épsilon. Estes achados evidenciam a enterotoxemia como doença de importância para criação de caprinos no Rio Grande do Sul.Five outbreaks of caprine enterotoxaemia in Rio Grande do Sul, Brazil, were studied.

Estes resultados apontam, quanto a distintas condições do ambiente de mercado: o efeito positivo da taxa de crescimento da produtividade na fronteira tecnológica sobre a concentração de mercado; o efeito ambíguo do aprendizado, capaz de produzir um lock-in de firmas inovadoras pioneiras em tecnologias que se tornam eventualmente obsoletas; o efeito "anti-seletivo" de taxas de juros muito elevadas, endividando e prejudicando o esforço de investimento e o sucesso competitivo das inovadoras em benefício das imitadoras. Quanto à simulação das estratégias de preços, constatou-se: a maior seletividade de estratégias em que as firmas inovadoras dão mais peso ao mark-up desejado, gerando maior concentração de mercado, efeito que é atenuado pelo crescimento da demanda e pelo aprendizado; a importância, para a sobrevivência de empresas menos inovadoras, do feedback do desempenho competitivo sobre o mark-up desejado e o efetivo, aumentando a adaptabilidade das empresas às condições de seleção do mercado.This paper presents a sectoral evolutionary simulation model combining neo-Schumpeterian and Post-Keynesian microfoundations, and exhibits some preliminary results. As to different market environment conditions, the simulations suggest: a positive effect of productivity growth of the technological frontier on market concentration; an ambiguous result of "learning by doing", from which innovation leaders may be found "locked in" new technologies that eventually become obsolete; a "counter-selective" effect of very high interest rates which may increase innovators indebtedness to the extent of impairing their investment efforts and competitive success as compared to some imitators.

A amostragem da vegetação foi feita pelo método de parcelas, sendo registrado o diâmetro à altura do peito (DAP e a altura dos indivíduos > 1 m de altura. Os resultados indicaram que a floresta plantada apresenta menores valores de DAP médio e área basal, e maior densidade de troncos em relação à floresta natural. A distribuição de indivíduos por classes de altura e a distribuição de troncos por classes diamétricas mostraram que a floresta plantada é mais jovem. Laguncularia racemosa e Rhizophora mangle ocorreram em ambas as florestas, enquanto Avicennia schaueriana foi registrada apenas na floresta plantada. Laguncularia racemosa apresentou maior dominância e densidade relativa em todos os sítios analisados, provavelmente, por ser característica de locais com menor influência marinha e pelo fato do estuário ter sido alterado por perturbações antrópicas.

    Full Text Available This paper analyses the availability of public resources for Brazilian cultural policies. The study comes from an intrinsic relation between culture and politics, between ways of seeing, living and thinking the world and its political consequences, identifying the umbilical link between culture and hegemony in classes societies. Analyses laws based on tax waiver, specifically patronage, which presented annual values similar to the Ministry of Culture budget itself; and Living Culture Program, which represented a significant change in State intervention in cultural themes. It concludes that incentive laws mean losses in democratic control and also reproduce regional inequalities, with higher resources concentration in São Paulo and Rio de Janeiro, acting as marketing tool for large corporations. Living Culture Program, on the other hand, presents a more equality public resources distribution, but is still contemplated with a derisive budget compared to incentive laws.

In the 70’s, all the teachers of the Department wrote a book together: “Fundamental Biochemistry”. This book was always used in the classes by groups of students of different careers supervised by the respective teacher. At the same time, this methodology was not used by pharmaceutical teachers, but they recommended the Department’s book to their students. Along the next years, Biochemistry teaching was adapted according to the professional course and to the teacher’s personal characteristics. Today, there are two extremes strategies again: one traditional for the most basic biochemistry student’s formation (including theoretical, laboratorial, seminars and informatics classes and the other, experimental-clinical, for physician’s formation (including seminars of molecular approach to the most prevalent diseases, mainly, those leading to failure of organs/systems and the interaction with patients from HCPA by the interpretation of their biochemical data. On the other hand, the Post Graduation Program, at first, emphasized biochemistry teaching in a traditional form, but gradually changed the emphasis to investigation, and most classes changed to scientific paper reports. To stimulate the teaching formation, two activities were offered to post-graduation students: Biochemistry Teaching Methodology and Teaching Practice in Biochemistry.

Tal disjunção se deve, entre outros fatores, à predominância de obras canônicas no currículo escolar, à natureza impressa do livro didático e a um entendimento restrito do que seja o texto literário. Por outro lado, assistimos ao uso crescente de aparelhos celulares e smartphones em sala de aula, raramente articulado ao processo de ensino-aprendizagem, ainda que esses dispositivos possam integrar práticas de letramento literário na esfera digital. No presente artigo, discutem-se questões teórico-metodológicas acerca do uso, em sala de aula, de celulares e smartphones para o trabalho com um gênero literário emergente: a Twitteratura.

    Two important Proterozoic metasedimentary sequences, the Rio Preto and Santo Onofre Groups, crop out along the northwestern margin of the Sao Francisco craton and in northern Paramirim corridor, respectively. The Rio Preto Group, involved in the eponymous fold-thrust belt along the northwestern cratonic boundary, comprises the Formosa (garnet schist, quartz schist, quartzite, chlorite-sericite schist and ferriferrous quartz schist) and Canabravinha (quartzite, micaceous quartzite, metarhytmite, phylite, schist and metaturbidite) formations. The Santo Onofre Group occurs exclusively in the Paramirim corridor, and is composed of quartzite and minor carbonaceous or Mn-rich phylite. These units record sedimentation in shallow to deep-water marine settings related to rift basins, and were deformed and metamorphosed under green schist facies conditions during the Brasiliano orogeny. Here we present 427 new detrital zircon U-Pb ages, which constrain the maximum depositional ages of ca. 971 Ma for the Santo Onofre Group, ca. 912 Ma for the Canabravinha Formation, and ca. 65 Ma for the Formosa Formation of the Rio Preto Group. Our data suggests that the Santo Onofre and the Rio Preto Groups accumulated in two distinct basin settings. The latter, composed mostly of sandy rocks, would represent a relatively stable, shallow-marine shelf environment. The Rio Preto Group, with metadiamictite, quartzite, pelitic and rhythmitic rocks, represents a shallow to deep marine environment influenced by gravity flows. Both groups were probably deposited in the Late Tonian, and are potential correlatives of the lower (pre-glacial) units of the Macaubas Group of the Aracuai belt. (author)

    Full Text Available This article aims at a critical analysis about the Brazilian narrative, considering aspects of the Os contos de Belazarte, written by Mário de Andrade, striking work that seeks to approach the situation regarding the social and economic crisis which introduces the Brazilian face of the changes that result in the Revolution of 1930. This period of Brazilian political life transformations induces the modernist writers to effectuation of instances of participation as critical outbreak marks situation of underdevelopment of the country. In turn, the social approach contained in these tales is not the cliché of Manichaeism flaunting victory literary of socialism as a system devised. To distance themselves from the object of his narrative, Mário de Andrade never ceases to put in evidence the contradictions inherent to forms of exploitation of labour in a country of dependent economy that has in São Paulo the center of its industrial production. Os contos de Belazarte, therefore, show the unequal aspects of a society in formation to which competes the activity of underlings exploited in its productive capacity.

O Sistema Único de Saúde, cujas deretrizes preconizam a atenção universal e eqüânime, determina a relevância desta temática dentro do campo da avaliação dos serviços de saúde. Assim, foram estudados dois ambulatórios de pediatria de um hospital universitário, um geral e outro de uma subespecialiadade (pneumologia, comparando os usuários quanto ao acesso. MÉTODO: Foram aplicados 221 questionários entre clientes de ambos os ambulatórios de pediatria com o objetivo de se estudar e comparar variáveis socioeconômicas, procedência, acesso aos referidos ambulatórios e outros serviços de saúde. RESULTADOS: Evidenciou-se grande dificuldade de locomoção dos pacientes, a maioria dos quais são encaminhados por serviços de saúde locais. Dos pacientes atendidos 40% não receberam nenhum atendimento anteriormente à sua chegada ao hospital, fato que decorre principalmente de seu baixo nível socioeconômico, que os torna dependentes exclusivamente dos serviços públicos de saúde. A comparação entre os dois ambulatórios mostra que os pacientes do ambulatório de especialidade têm melhor nível socioeconômico e são menos dependentes dos serviços públicos, configurando desta forma uma situação de ineqüidade. CONCLUSÕES: É apontado o melhor nível socioeconômico dos usuários da especialidade bem como questões organizacionais do próprio serviço como os responsáveis pela iniqüidade verificada.

    The Rio Dulce National Park is one of Guatemala's major environmental assets. The park contains the remaining remnants of an eastern Guatemalan tropical rainforest which has good but fast deteriorating value for the development of the ecotourism industry. The governmenial objective for the region as stated in the Master Plan for the park is ecotourism development and protection of biodiversity. The decisions to be made concerning the long-term, sustainable use of the natural resources of the Rio Dulce region appear to be directed by existing environmental laws and the Rio Dulce Master Plan. However, the wording of these instruments is ambiguous and lacks specific definitions and criteria for making necessary determinations. This, in combination with lack of enforcement in the region, has led to extensive disparity in interpretation of the laws and uncontrolled, conflicting actions by individuals and organizations.

    Full Text Available RESUMO Este artigo tem por objetivo refletir sobre o contributo específico dos territórios - a casa, a rua, o entorno - enquanto referência fundamental na construção identitária de pessoas idosas. Nossa base reflexiva foi construída a partir de observações e descrições do território conhecido como "Alta", no casco histórico de Coimbra, Portugal; entrevistas semiestruturadas, com 12 de seus residentes; e com notas de campo, sistematizadas num diário de bordo da pesquisa, construído para o efeito. A construção identitária de grande parte das pessoas idosas encontra-se profundamente ancorada nos territórios onde vivem, principalmente quando estas pessoas residem há muito tempo em um mesmo espaço geográfico, no qual vivenciam uma parte muito substantiva do seu cotidiano. Esta centralidade é, ainda, reforçada quando apresentam mobilidades reduzidas ou condicionadas, quer pelas dificuldades de acessibilidade dos próprios territórios, quer por limitações pessoais, iniciadas e/ou acentuadas na velhice.

Porém, muitos ideais tradicionais de gênero persistem no subconsciente do indivíduo (Goldenberg, 2000. A identidade masculina é construída a partir da negação - negando atributos relacionados à mulher, à criança ou ao homossexual - e aqueles que se consideram fora do padrão dominante de masculinidade ainda demonstram medo de serem vistos como homossexuais (Badinter, 1993, e outros. O consumo de beleza está associado ao desejo de promover um aumento da atratividade física e a obtenção dos benefícios sociais correspondentes (Bloch e Richins, 1992. Como a atratividade física é considerada um elemento central da feminilidade, o consumo de práticas de beleza costuma ser maior entre as mulheres. A identidade de gênero masculina está associada a menor preocupação com a aparência, assim, os homens estão menos inclinados a adotarem práticas de beleza. Neste contexto, como pesquisar o tema beleza entre os homens? O objetivo deste estudo exploratório foi contribuir para uma melhor compreensão sobre o consumidor masculino de produtos e serviços de beleza, refletindo sobre padrões estéticos e práticas relacionadas à beleza masculina. Os relatos foram obtidos através de entrevistas em profundidade, usando também técnica projetiva, com dez jovens homens de classe econômica alta no Rio de Janeiro. Diversos aspectos das práticas de beleza são manipulados pelos entrevistados na caracterização de papéis sociais e na construção das identidades de gênero. Poucas foram as práticas de beleza identificadas como permitidas para o gênero masculino. Eles vêem a beleza como facilitadora das relações sociais e amorosas, mas sucesso profissional e inteligência ainda parecem mais importantes. Homem não precisa ser bonito.

    The objective of this work is to show the need and the importance of the training and formation of the dentist in radioprotection, in accordance with the recent proposal of Technical Regulation Guidelines of Radiation Protection in radiodiagnostic in Medicine and Odontology, from the ministry of Health, which established basic for radioprotection in medicine and odontology, including the principles, limits, obligations and basic controls for protection of man and the environment, against possible improper effects caused by the use of ionizing radiation sources. Departing from results obtained previously by a research about training and Formation of the dentist in Radioprotection, in the state of Rio de Janeiro, a questionnaire was applied to know better the abilities of our dentist. Analysis of programs of disciplines in schools of dentist, in the sate of Rio de Janeiro indicate that they show little or no concern with radiological protection. This was confirmed through a first questionnaire applied to students, dentist teachers, which corroborates with results of the last questionnaire. This work suggests creation or adaptation of existent disciplines, involving radioprotection and quality of images in radiodiagnostic, to improve, complement, and make uniform the formation future dentists.

    Urban informality is typically ascribed to the urban poor in cities of the Global South. Drawing on Judith Butler's concept of performativity and taking the case of Rio de Janeiro in the context of the 2016 Olympic Games, this article conceptualizes informality as a signifier and a procedural, relational category. Specifically, it shows how different class actors have employed the signifier informality (1) to legitimize the confinement of marginalized populations; (2) to justify the organized efforts of the upper middle class to protect their 'self-enclosed' gated communities; and (3) to warrant the formation of opposition and alliances between inhabitants, activists, and researchers on the edges of the urban order. This article offers new perspectives to better understand the relationship between informality and confinement by examining the active role that inhabitants of marginalized settlements assume in the Olympic City.

    Full Text Available This study evaluates the effects of agricultural and urban activities on the structure and composition of benthic communities of streams in the state of Rio Grande do Sul, Brazil. Benthic macroinvertebrates were collected in streams influenced by urbanization and agriculture and in streams with no anthropogenic disturbances (reference streams. Organism density was superior in urban streams when compared with streams in the other two areas. The taxonomic richness and Shannon diversity index were higher in reference streams. The benthic fauna composition was significantly different among land uses. The classification and ordination analyses corroborated the results of variance analyses demonstrating the formation of clusters corresponding to streams with similar land use. Seasonality was also found to influence the benthic community, though in a lesser degree than land use.

    It is illustrated that a theoretical understanding of the formation and evolution of galaxies depends on an understanding of star formation, and especially of the factors influencing the rate of star formation. Some of the theoretical problems of star formation in galaxies, some approaches that have been considered in models of galaxy evolution, and some possible observational tests that may help to clarify which processes or models are most relevant are reviewed. The material is presented under the following headings: power-law models for star formation, star formation processes (conditions required, ways of achieving these conditions), observational indications and tests, and measures of star formation rates in galaxies. 49 references

    2011-12-01

    Introduction Due to high water demand, the scarcity of water, and the complexity of water allocation, environmental flows have not been considered as an integral part of the water management in the Rio Grande/Rio Bravo transboundary basin. The Big Bend reach is located between the cities of Presidio/Ojinaga to Amistad international reservoir, along the main stream (Fig. 1). Important environmental habitats such as the Big Bend National and State Park in the U.S., the Maderas del Carmen, Cañon de Santa Elena and Ocampo natural reserved areas in Mexico are ecologically threatened because of the lack of environmental water management policies. Several efforts have been undertaken by scientists, government agencies and NGOs to determine the environmental flows for this reach and water management policies that can provide these flows. Objective The objective of this research is to describe a water management policy that can conciliate environmental and human water uses in the Big Bend region. In other words, define a policy that can provide environmental flows without harming water supply for stakeholders or increasing flood risk, within legal and physical constraints of the system. Methodology First, the system was characterized identifying water users, hydraulic infrastructure, and water allocation according to state, federal and international regulations. Second, a hydrograph for environmental flows was proposed that mimics the hydrologic characteristics of the prior dam alteration. Third, a water planning model was constructed to evaluate alternative policies. Fourth, the water management is proposed to provide environmental restoration flows from Luis L. Leon reservoir. This policy considers mechanisms that reduce flooding and drought risks, while meting national and international water regulations. Results Three types of natural flow regimes are considered: (1) median flows aimed to provide the base flow in the region, (2) high flows to provide transversal

  15. Formate Formation and Formate Conversion in Biological Fuels Production

    2011-01-01

    Full Text Available Biomethanation is a mature technology for fuel production. Fourth generation biofuels research will focus on sequestering CO2 and providing carbon-neutral or carbon-negative strategies to cope with dwindling fossil fuel supplies and environmental impact. Formate is an important intermediate in the methanogenic breakdown of complex organic material and serves as an important precursor for biological fuels production in the form of methane, hydrogen, and potentially methanol. Formate is produced by either CoA-dependent cleavage of pyruvate or enzymatic reduction of CO2 in an NADH- or ferredoxin-dependent manner. Formate is consumed through oxidation to CO2 and H2 or can be further reduced via the Wood-Ljungdahl pathway for carbon fixation or industrially for the production of methanol. Here, we review the enzymes involved in the interconversion of formate and discuss potential applications for biofuels production.

  16. Assessment of hydrologic transport of radionuclides from the Rio Blanco underground nuclear test site, Colorado

    1996-10-01

    DOE is operating an environmental restoration program to characterize, remediate, and close non-Nevada Test Site locations used for nuclear testing. Evaluation of radionuclide transport by groundwater is part of preliminary risk analysis. These evaluations allow prioritization of test areas in terms of risk, provide a basis for discussions with regulators and the public about future work, and provide a framework for assessing site characterization data needs. The Rio Blanco site in Colorado was the location of the simultaneous detonation of three 30-kiloton nuclear devices. The devices were located 1780, 1899, and 2039 below ground surface in the Fort Union and Mesaverde formations. Although all the bedrock formations at the site are thought to contain water, those below the Green River Formation (below 1000 in depth) are also gas-bearing, and have very low permeabilities. The transport scenario evaluated was the migration of radionuclides from the blast-created cavity through the Fort Union Formation. Transport calculations were performed using the solute flux method, with input based on the limited data available for the site. Model results suggest that radionuclides from the test are contained entirely within the area currently administered by DOE. This modeling was performed to investigate how the uncertainty in various physical parameters affect radionuclide transport at the site, and to serve as a starting point for discussion regarding further investigation; it was not intended to be a definitive simulation of migration pathways or radionuclide concentration values. Given the sparse data, the modeling results may differ significantly from reality. Confidence in transport predictions can be increased by obtaining more site data, including the amount of radionuclides which would have been available for transport (i.e., not trapped in melt glass or vented during gas flow testing), and the hydraulic properties of the formation. 38 refs., 6 figs., 1 tab

    1994-08-01

    The distribution of nonmarine lithofacies, paleocurrents, and provenance data are used to define the evolution of late Oligocene and Miocene basins and complementary uplifts in the southern Rio Grande rift in the vicinity of Hatch, New Mexico, USA. The late Oligocene-middle Miocene Hayner Ranch Formation, which consists of a maximum of 1000 m of alluvial-fan, alluvial-flat, and lacustrine-carbonate lithofacies, was deposited in a narrow (12 km), northwest-trending, northeast-tilted half graben, whose footwall was the Caballo Mountains block. Stratigraphic separation on the border faults of the Caballo Mountains block was approximately 1615 m. An additional 854 m of stratigraphic separation along the Caballo Mountains border faults occurred during deposition of the middle-late Miocene Rincon Valley Formation, which is composed of up to 610 m of alluvial-fan, alluvial-flat, braided-fluvial, and gypsiferous playa lithofacies. Two new, north-trending fault blocks (Sierra de las Uvas and Dona Ana Mountains) and complementary west-northwest-tilted half graben also developed during Rincon Valley time, with approximately 549 m of stratigraphic separation along the border fault of the Sierra de las Uvas block. In latest Miocene and early Pliocene time, following deposition of the Rincon Valley Formation, movement continued along the border faults of the Caballo Mountains, Dona Ana Mountains, and Sierra de las Uvas blocks, and large parts of the Hayner Ranch and Rincon Valley basins were segmented into smaller fault blocks and basins by movement along new, largely north-trending faults. Analysis of the Hayner Ranch and Rincon Valley Formations, along with previous studies of the early Oligocene Bell Top Formation and late Pliocene-early Pleistocene Camp Rice Formation, indicate that the traditional two-stage model for development of the southern Rio Grande rift should be abandoned in favor of at least four episodes of block faulting beginning 35 Ma ago.

Os dados primários gerados pelos inventários compõem uma das ferramentas mais importantes na tomada de decisões a respeito do manejo de áreas naturais. Entretanto, vários problemas têm sido observados em diversos níveis relacionados aos inventários de fauna no Brasil e vão desde a formação de recursos humanos até a ausência de padronização, de desenho experimental e de seleção de métodos inadequados. São apresentados estudos de caso com mamíferos, répteis, anfíbios e peixes, nos quais são discutidos problemas como variabilidade temporal e métodos para detecção de fauna terrestre, sugerindo que tanto os inventários quanto os programas de monitoramento devam se estender por prazos maiores e que os inventários devem incluir diferentes metodologias para que os seus objetivos sejam plenamente alcançados.Inventories of fauna directly access the diversity of a locality in a certain period of time. The primary data generated by these inventories comprise one of the most important steps in decisions making regarding the management of natural areas. However, several problems have been observed at different levels related to inventories of fauna in Brazil, and range from the training of humans to the lack of standardization of experimental design and selection of inappropriate methods. We present case studies of mammals, reptiles, amphibians and fishes, where they discussed issues such temporal variability and methods for detection of terrestrial fauna, suggesting that both inventories and monitoring programs should be extended for longer terms and that inventories should include different methodologies to ensure that their goals are fully achieved.

    Full Text Available O Paraguai é o rio-tronco do trato de sistemas deposicionais do Pantanal. Com base em dados de sensores remotos e verificação de campo, foi realizado mapeamento geomorfológico da planície do rio Paraguai no trecho entre as confluências dos rios Cuiabá e Miranda, onde foram reconhecidas formas deposicionais atuais e antigas. A análise das associações de formas permitiu estabelecer proposta de evolução geomorfológica para a área, mas os eventos carecem ainda de datação precisa por métodos geocronológicos. Uma rede de drenagem abandonada multicanais está parcialmente preservada na planície, sendo composta por formas de canais com diques marginais que evidenciam período de menor descarga fluvial, provavelmente do Pleistoceno tardio ao Holoceno inferior. Um sistema constituído por paleocinturões de meandros trunca a paleorrede de drenagem multicanais, registrando aumento na umidade e na descarga fluvial. Sob essas condições o rio Paraguai construiu um sistema composto por cinturões de meandros com direção aproximada norte-sul no Holoceno inferior/médio.

    In Brazil economically important coal deposits occur in the southern part of the Parana Basin, where coal seams occur in the Permian Rio Bonito Formation, with major coal development in the states of Rio Grande de Sul and Santa Catarina. The current paper presents results on sequence stratigraphic interpretation of the coal-bearing strata, and petrological and geochemical coal seam characterization from the South Santa Catarina Coalfield, Parana Basin. In terms of sequence stratigraphic interpretation the precursor mires of the Santa Catarina coal seams formed in an estuarine-barrier shoreface depositional environment, with major peat accumulation in a high stand systems tract (Pre-Bonito and Bonito seams), a lowstand systems tract (Ponta Alta seam, seam A, seam B) and a transgressive systems tract (Irapua, Barro Branco and Treviso seams). Seam thicknesses range from 1.70 to 2.39 m, but high proportions of impure coal (coaly shale and shaley coal), carbonaceous shale and partings reduce the net coal thickness significantly. Coal lithoypes are variable, with banded coal predominant in the Barro Branco seam, and banded dull and dull coal predominantly in Bonito and Irapua seams, respectively. Results from petrographic analyses indicate a vitrinite reflectance range from 0.76 to 1.63 %Rrandom (HVB A to LVB coal). Maceral group distribution varies significantly, with the Barro Branco seam having the highest vitrinite content (mean 67.5 vol%), whereas the Irapua seam has the highest inertinite content (33.8 vol%). Liptinite mean values range from 7.8 vol% (Barro Branco seam) to 22.5 vol% (Irapua seam). Results from proximate analyses indicate for the three seams high ash yields (50.2 - 64.2 wt.%). Considering the International Classification of in-Seam Coals, all samples are in fact classified as carbonaceous rocks (> 50 wt.% ash). Sulfur contents range from 3.4 to 7.7 wt.%, of which the major part occurs as pyritic sulfur. Results of X-ray diffraction indicate the

    First palynological information from surface samples of the Serra Alta and Rio do Rasto formations (Passa Dois Group, Paraná Basin), exposed in the Serra do Rio do Rastro (White's Column) and Urubici regions in Santa Catarina State (Brazil) is presented. The Serra Alta Formation is transitionally deposited over the Irati Formation, which is constrained to the late Artinskian/Kungurian by different paleontological and radiometric data. Twelve productive samples (of forty) yielded fairly well preserved palynomorphs, dominated by striate and non striate bisaccate and asaccate pollen grains and subordinated trilete and monolete spores, monosaccate pollen grains and Botryococcus. Diagnostic species of the Lueckisporites virkkiae Zone (Artinskian-Guadalupian) in the Paraná Basin are recorded along with few species of Guadalupian-Lopingian age (e.g. Cladaitina veteadensis, Guttulapollenites hannonicus, Lophotriletes parryensis, Protohaploxypinus microcorpus, Staurosaccites quadrifidus, Weylandites cincinnatus). They support a Kungurian-?Roadian age for the Serra Alta, and a Capitanian (?Lopingian) age for the Rio do Rasto formations. Four samples from the Sete Quedas outcrop yielded scarce and poorly preserved specimens of Lueckisporites likely due to weathering. A statistic comparison among our assemblages and selected Permian palynozones and palynofloras from South America supports a closer correlation with the La Veteada Formation (Guadalupian-Lopingian) from western Argentina due to common occurrence of all the species, and with the Striatites Zone (late Artinskian-Kungurian) of the Chacoparaná Basin, and the I-S Zone Melo Formation in Uruguay. The botanical affinities of the palynomorphs from both assemblages indicate the presence of spores of hygro-mesophytic affinities along with meso-xerophyle pollen grains, which is in agreement with seasonally warmer and humid climates favored by a lower paleolatitude position. The presence of pyrite in some of the miospore

    2012-05-01

    Two decades after the 1992 Rio Conference, we must admit to collective failure in combating human-induced climate change. The problem is not that no efforts have been undertaken, but that these efforts have just not been enough. We cannot escape serious climate disruption - which, to some extent, has already begun - if we keep going down that road. We must change direction, and we must move quickly. To this end, we call in this paper for a fine-tuning of the international negotiations on climate. We propose refocusing these international efforts on negotiating a global carbon price signal, harmonized in principle but flexible in practice, instead of doggedly spending the next few years attempting to convince countries to accept stricter national targets for quantitative reduction of their greenhouse gas (GHG) emissions. We cannot afford to spend the next few years missing the wrong targets. Simply put, we must move away, collectively, from an ineffective logic of constraint to a pragmatic logic of price incentives. The December 2011 Durban Conference proved, once again, that the 'to each their own target' approach does not work. We must instead adopt a 'one price signal for all' strategy. If there were a single reason to improve the current mitigation logic, it would be this evident fact: developing countries, which now account for 60% of emissions worldwide, cannot accept what they perceive as an obstacle to their economic development, when developed countries have been able to get rich on unlimited use of fossil fuel energy. Indeed, in the foreseeable future, emerging economies, particularly China and India with Gross Domestic Product (GDP) annual growth rates of between 8% and 10%, will not accept absolute reduction targets for GHG emissions. On the other hand, these countries might be more open to the idea of a flexible levy of a price per tonne of carbon dioxide, a price from which they would derive revenues, and which their economic

    Full Text Available Within the plethora of reading possibilities of Mário de Andrade’s works and the analysis of his artistic persona, seeking  knowledge about him, about the other, about Brazil, and about art,  sounds richer, since it challenges the researcher to face some issues of philosophy, such as will power, consciousness, freedom, subjectivity. In order to support our ideas, we refer to Hegel, mainly his article Aesthetics delimitation and refutation of some objections against Art Philosophy (Aesthetics Course I, 2001 from which we have taken the concept of formalizing freedom, since it can be considered adequate to understand Mário de Andrade’s artistic trajectory. Besides, the concepts of thinking freedom and thinking knowledge freedom, also dealt with in the same article, are pertinent to the present essay since, they are related to issues concerning autonomy, judgment and consciousness regarding art.

    In the run-up to the Rio+20 summit, which takes place in June 2012, this study investigates the current system for financing international environmental governance (IEG). The current architecture for IEG finance consists of a growing number of bilateral and multilateral actors, funds and financial mechanisms which leads to incoherence, inefficiencies and extra burdens on recipient countries. The resulting intransparency is exerbated by the lack of a comprehensive system for tracking. Against this background, this study investigates the current state of the IEG funding system from a qualitative and - to a lesser degree - quantitative angle. Some of its flaws are discussed as are options for its improvement - all with a view to formulating recommendations for the Rio+20 summit.

    Godfrey, Brian J; Arguinzoni, Olivia M

    2012-01-01

    Despite the fortification of buildings, streets, and public squares, Rio de Janeiro's beaches remain widely regarded as democratic spaces of social diversity and accessibility. Our study revisits the question of Rio's “democratic” beachfronts, based on local interviews, field observations, official reports, and newspaper accounts. We focus on historical and contemporary perceptions of planning, privatization, and public-order programs on the city's southern seaside. Institutional discourses have justified increasing regulation to combat threats of disorder and insecurity. While residents value the relative openness of beachfronts, they also acknowledge issues of safety, social segmentation, and subtle forms of bias. The public generally applauds recent “Shock of Order” policing and commercial revitalization, although critics lament the loss of traditional freedoms for informal beach vendors and casual sports. These paradoxes highlight enduring tensions between social order and hierarchy on one hand, and democratic rights and equality on the other.

    Ten years after the initial Climate Change Convention from Rio in 1992, the developed world is likely to ratify the Kyoto Protocol which has been celebrated as a milestone in climate protection. Standard economic theory, however, casts doubt that Kyoto will go beyond symbolic policy. In this paper we show that the final concretion of the Kyoto Protocol obeys the theoretical prediction: Kyoto more or less boils down to business-as-usual without significant compliance costs to ratifying parties.

  8. Floodplain construction of the Rio Grande at El Paso, Texas, USA: response to Holocene climate change

    Science.gov (United States)

    Hall, Stephen A.; Peterson, John A.

    2013-04-01

    The Rio Grande is one of the larger rivers in North America, and the development of its floodplain is related to Holocene climate and climate change. The late Pleistocene through early Holocene channel is characterized by a meander or braided system with lateral cutting and backfilling, resulting in the valley-wide deposition of massive to cross-bedded, fine-to-medium textured sand. The late Pleistocene-early Holocene floodplain is also the sand source for the adjacent Bolson sand sheet. The sand sheet stopped accumulating new sand 5000 yrs ago, an event directly related to the shutting off of the sand supply caused by the deposition of overbank muds that covered and sealed the floodplain surface. During the middle Holocene, the river may have dried intermittently with the floodplain becoming deflated and local sand dunes forming on the floodplain. After 5000 yrs the climate was less arid and the river shifted to a regime of increased flooding and overbank deposition of silt and clay. By 2500 yrs, a late Holocene period of wet climate resulted in further overbank deposition and the formation of a cumulic Mollisol across the floodplain, the Socorro paleosol. The period of wet climate corresponds to the Audubon Neoglacial and active rock glaciers in the southern Rocky Mountains, speleothem growth in nearby caves, and other evidence for wet-cool conditions in the region. After 1000 yrs, the climate became drier, and the deposition and accumulation of overbank muds by the flooding Rio Grande came to a halt. Even though the river has flooded often in historic times, and presumably during late prehistoric times as well, there is little evidence for deposition of overbank sediments on the floodplain since A.D. 1000. Accordingly, the present-day surface of the Lower Valley is ten centuries old. Three channels occur on the US side of the Lower Valley floodplain, and during the past 2500 yrs stream flow has shifted from one to the other by the avulsion process of channel

    In situ measurements of water level, temperature and pH in 8 wells of the limestone rocks of the Bambui and Caatinga Formation, in the Rio Verde basin, were taken in August, September, October, November and December 1979 and in April and October of 1980. Samples of precipitation and surface waters in the region and ground water of that wells were analyzed for the content of Ca ++ , Mg ++ , Na + , K + , SO =4 HCO - 3 , Cl - and isotopic ratios D/H and 18 O/ 16 O. For the groundwater samples it was also determined the radiocarbon activity and isotopic ratio 13 C/ 12 C of the dissolved carbonates the parameters determined were used to analyze the factors that control the groundwaters in the region within the hydrological cycle as well as an eventual leak into the region of water from the nearly reservoir of Sobradinho. No relation was found between the groundwaters an the Sobradinho reservoir. Their apparent carbon-14 ages range from 2300 to 13640 years. As all samples come from a small area this indicates a heterogenous and complex aquifer. The data of isotopic ratio D/H and 18 O/ 16 O and the righ carbon-14 ages of the ground water suggest neether direct recharge from precipitation or correlations between the waters of Rio Verde and the aquifer. The chemical data of the slightly saline groundwater with differences in the chemical ratios with respect to the surface samples suggests some dissolution in addition to evaporation as the mechanisms that control the salt content in the aquifer.

  10. Rio de Janeiro's Waterfront: Urbanism and social representation of reality

    Directory of Open Access Journals (Sweden)

    2002-09-01

    Full Text Available Post-modernity and economic globalization is inciting the competition among countries, regions and cities, in search of investments, consumers and resources. To pursue a new position in this global market, cities use new urban practices to re-discover and re-invent their identities and traditions, taken as attributes to attract consumers. In the city of Rio de Janeiro, the mythical dimension of the South Zone is inseparable and incorporated to its identity. In evaluating the history of Rio de Janeiro’s seaside, the social construction of its imagery and the projects that redesigned its urban signs, we can identify an intermittence of urban interventions, marked by the lack of a continuous management of the waterfront. We verify that, even though tourist marketing appraises the seaside as the main image of the city, it does not receive proportional attention from urban interventions, may be in account of not being understood as a social construction. We conclude that the importance of caring for the seaside must not be understood only as an esthetical question, but also as the valorization of Rio de Janeiro’s image, its inhabitants’ self-esteem and citizenship itself.

    Supplemental structural bracing was designed and installed for the 180-ft-tall Colony Tower, an experimental oil shale processing retort structure, in anticipation of its lateral response to the Rio Blanco detonation. The tower is a steel structure with both horizontal and vertical diagonal bracing. Data obtained from the earlier Project Rulison detonation indicated that an evaluation study was necessary. Design criteria that would provide an adequate margin of safety were developed based on predicted Rio Blanco ground motion. The evaluation of the unmodified structure showed that several bracing members would be subjected to forces exceeding their yield strength, and some would reach a level at which failure could occur. Further analyses were made with assumed modified bracing members. A final scheme for modified vertical bracing was established and installed. After modification, the response of the tower during the Rio Blanco detonation was measured by instruments on the ground and at various locations on the tower, and no evidence of damage was discovered. The modification of the Colony Tower and the procedures used to determine these modifications show the usefulness of current ground motion and structural response prediction technology for forecasting dynamic behavior of important structures subjected to ground motion from underground nuclear explosions.

Nestas, há pontos de monitoramento de alguns parâmetros de qualidade de água realizados pelo Programa Intermunicipal da Água. O objetivo do presente trabalho foi realizar a análise da qualidade de água nesses vários pontos de monitoramento nos principais rios desse município. Para entender melhor os recursos hídricos da região em termos tanto de qualidade quanto de quantidade, foram feitas análises de correlações entre os dados monitorados de qualidade de água e os dados de vazão diários simulados pelo modelo SWAT. Não se encontrou correlação significativa entre os dados de vazão simulados pelo modelo SWAT e os dados de qualidade de água em todos os pontos analisados. Foi identificado que os rios Serrinhas e Banhado, os quais se localizam na bacia do rio Negrinho, apresentaram índices de qualidade de água inferiores aos demais rios estudados devido principalmente aos efluentes provindos da urbanização. Foi identificado que há medianas, vários outlier e valores extremos dos parâmetros de DBO e OD que ficaram muito acima da legislação vigente.

  14. Patterns of gall infestation in Heteropterys byrsonimifolia A. Juss. in a forest-savannah ecotone

    Marcela de Castro Nunes Santos Terra

    Full Text Available ABSTRACT Galls are the result of a specific interaction between an inducer and a host plant. The species Heteropterys byrsonimifolia A. Juss. occurs in abundance in semideciduous seasonal forest ecotones and adjacent open formations. In the ecological reserve Quedas do Rio Bonito, located in the state of Minas Gerais, Brazil, this species is affected by a single gall morphotype. The present study aimed to evaluate whether the structural complexity of the host (test of the structural complexity hypothesis and the distance between hosts (test of the resource concentration hypothesis affect gall density in H. byrsonimifolia and to characterize the spatial distribution of the infestation. The results corroborate the two hypotheses tested, suggesting a metapopulation pattern of gall infestation in H. byrsonimifolia. Gallers were more successful in abrupt forest-savannah transition environments, which may be associated with greater stress-induced host vulnerability that plants usually experience in ecotones.

    Full Text Available Este artigo analisou a desigualdade ambiental em Rio das Ostras-RJ por meio do mapeamento das condições adequadas de habitação, baseada nos índices de abastecimento de água, de esgotamento sanitário, de alfabetização, de renda, de disposição do lixo e de presença de vegetação, oriundos do Censo IBGE de 2010 e de imagens de satélite Cbers-2b e Landsat-5, de 2008. Os índices foram ponderados pelo método Analitic Hierarchy Process e agregados no software ArcGis 10.0, construindo o índice de desigualdade ambiental. O município de Rio das Ostras foi selecionado por apresentar um elevado crescimento populacional entre 2000 e 2010, seguido de um significativo crescimento econômico derivado da exploração de petróleo e gás na Bacia de Campos. Nesse sentido, tornou-se importante verificar se o crescimento populacional e econômico vinha acompanhando de condições de habitação adequadas para toda a população. O resultado expôs a presença de desigualdade ambiental em Rio das Ostras, afetando principalmente a população de menor renda, com maiores porcentagens de analfabetos e localizados no limite da área urbanizada e na área rural, cujas áreas apresentaram deficiência na oferta de serviços e infraestrutura. Concluiu-se que a distribuição condições adequadas de habitação avaliada por este trabalho não é homogênea e segue a lógica de valorização da terra urbana para o processo de especulação imobiliária em Rio das Ostras. A presença da desigualdade ambiental também representa dificuldades na garantia da sustentabilidade urbana, com diversas áreas desprovidas de condições de habitação em que, por isso, acabam por impactar o meio ambiente.

  17. Microbial contamination and chemical toxicity of the Rio Grande

    Full Text Available Abstract Background The Rio Grande River is the natural boundary between U.S. and Mexico from El Paso, TX to Brownsville, TX. and is one of the major water resources of the area. Agriculture, farming, maquiladora industry, domestic activities, as well as differences in disposal regulations and enforcement increase the contamination potential of water supplies along the border region. Therefore, continuous and accurate assessment of the quality of water supplies is of paramount importance. The objectives of this study were to monitor water quality of the Rio Grande and to determine if any correlations exist between fecal coliforms, E. coli, chemical toxicity as determined by Botsford's assay, H. pylori presence, and environmental parameters. Seven sites along a 112-Km segment of the Rio Grande from Sunland Park, NM to Fort Hancock, TX were sampled on a monthly basis between January 2000 and December 2002. Results The results showed great variability in the number of fecal coliforms, and E. coli on a month-to-month basis. Fecal coliforms ranged between 0–106 CFU/100 ml while E. coli ranged between 6 to > 2419 MPN. H. pylori showed positive detection for all the sites at different times. Toxicity ranged between 0 to 94% of inhibition capacity (IC. Since values above 50% are considered to be toxic, most of the sites displayed significant chemical toxicity at different times of the year. No significant correlations were observed between microbial indicators and chemical toxicity. Conclusion The results of the present study indicate that the 112-Km segment of the Rio Grande river from Sunland Park, NM to Fort Hancock, TX exceeds the standards for contact recreation water on a continuous basis. In addition, the presence of chemical toxicity in most sites along the 112-Km segment indicates that water quality is an area of concern for the bi-national region. The presence of H. pylori adds to the potential health hazards of the Rio Grande. Since no

    Full Text Available ABSTRACT: The evaluation of soils in representative landscapes constitutes an opportunity to evaluate spatial distribution, discuss formation processes, and apply this knowledge to land use and management. In this sense, from the perspective of an environmentally diversified region, the aim of the present study is to evaluate the occurrence and understand the formation of soils in different geomorphic surfaces of a landscape from a mountain region in the state of Rio de Janeiro. The study was developed in the Pito Aceso microbasin in the municipality of Bom Jardim, composed of narrow valleys and a rugged mountain domain, with elevation between 640 and 1,270 m. In a representative landscape, the geomorphic surfaces were obtained from the slope segments and flow lines. On the geomorphic surfaces, soil profiles were described by their morphological properties, collected, and analyzed to describe the chemical and physical properties of each horizon. Geomorphological aspects and possible variations of the parent material directly affected pedogenesis and led to distinct soil classes in the landscape. Variation in the geomorphic surfaces directs the processes for soil formation under current conditions, as well as the preservation of polygenetic soils. Soils of lower development and with greater participation of the exchangeable cations were identified at the summit (talus deposit (Neossolo Litólico and Cambissolo Húmico and toeslope (colluvial-alluvial (Neossolo Flúvico, whereas more developed soils with lower nutrient content occur in the concave (Argissolos Vermelho and Amarelo and convex (Latossolo Amarelo backslope, except for the Argissolo Vermelho-Amarelo in the shoulder, which had high exchangeable cations contents.

At the moment, ESS Bilbao uses this middleware to perform the control of their Ion Source Hydrogen Positive (ISHP) project. The implementation of the control system was based on: PXI Real Time controllers using the LabVIEW-RT and LabVIEW-EPICS tools; and RIO devices based on Field-Programmable Gate Array (FPGA) technology. Intended to provide a full compliant EPICS IOCs for RIO devices and to avoid additional efforts on the system maintainability, a migration of the current system to a derivative Red Hat Linux (CentOS) environment has been conducted. This paper presents a real application case study for using the NIRIO EPICS device support (NIRIO-EDS) to give support to the ISHP. Although RIO FPGA configurations are particular solutions for ISHP performance, the NIRIO-EDS has permitted the control and monitoring of devices by applying a well-defined design methodology into the previous FPGA configuration for RIO/FlexRIO devices. This methodology has permitted a fast and easy deployment for the new robust, scalable and maintainable software to support RIO devices into the ISHP control architecture.

    today is less about exercising the authority of an office and more about embodying authenticity. I argue that traditional homiletic education can benefit from implementing a learner-centered approach to teaching moving from sermon formation towards preacher formation, in order to develop and train...... preachers. This involves a learning strategy to ministry where theological skills, pastoral competences, and own personality are interwoven. Teaching here means facilitating a room of learning where teacher’s power and control is reduced, allowing the preacher to reflect upon own practice without being...... judged, evaluated, or critiqued. In this paper, I explain how a learner-centered approach to education works in practice and show how pastors experience the teaching method and the congregations’ positive response to their improvements.

    Full Text Available O PRESENTE artigo resume parte dos resultados de um amplo projeto sobre o Brasil ante cenários internacionais possíveis. Adotando a postura prospectiva que informou todo esse projeto, o artigo indica algumas das linhas de força que deverão estabelecer o elo entre o sistema internacional presente e o que haverá no futuro, em um horizonte de vinte anos, destacando entre outros o papel dos EUA, da Europa e da China nesse processo. Quatro cenários são utilizados como base para a análise do caso brasileiro: Desconcentração conflituosa, Multipolaridade benigna, Unipolar consolidado e Ordem liberal cosmopolita. Considera-se aqui o Brasil como um país intermediário, afastado das áreas críticas de tensão internacional, e que, portanto, dispõe de certa margem de manobra e razoável condição para definir suas estratégias internacionais.THIS article presents part of the results of a broad research about Brazil and international scenarios. Assuming the same prospective view of the research project, this article indicates a few current driving forces that will contribute to define international order in the future, in a 20 years perspective. The roles of the USA, Europe and China are highlighted in this analysis. Four scenarios are used as parameters for the analysis of the Brazilian case: conflictive deconcentration, benign multipolarity; consolidated unipolarity and cosmopolitan liberal order. We consider Brazil as an Intermediate State out of the critical areas of international conflict. We also consider that Brazil has certain margin for maneuver and reasonable amount of capacity to define its international strategies.

  19. Desenvolvimento de concretos refratários multifuncionais

    2001-01-01

    Full Text Available A facilidade de aplicação dos concretos tem sido uma das principais justificativas da substituição de peças moldadas por refratários monolíticos. Todavia, as inúmeras técnicas disponíveis para aplicação dos monolíticos têm resultado em uma diversificação muito acentuada das classes de concreto refratário (p. ex., vibrados, projetados, auto-escoantes, "shotcreting". Em virtude disso, há atualmente uma crescente demanda por concretos de maior versatilidade, denominados multifuncionais, que possibilitem a utilização das mais variadas técnicas para aplicação. No entanto, ainda questiona-se se a versatilidade dos concretos multifuncionais durante a aplicação também implica em benefícios com relação à etapa de mistura e ao seu desempenho a altas temperaturas. O objetivo deste trabalho é identificar os requisitos necessários para a obtenção de concretos multifuncionais, e comparar o seu comportamento reológico e resistência à fluência a quente com concretos normalmente aplicados com técnicas específicas de instalação. Os resultados indicam que a distribuição granulométrica é a principal determinante da característica multifuncional de concretos de alta alumina com ultra-baixo teor de cimento.

    Full Text Available Because of the tendency all over the planet on grouping macroeconomic regional blocks, the study of the Community Law, as a new law's subject, has becoming a necessity not only among the responsible by the project destination, but also among those that have already understood that globalization, more than irreversible, is “irresistible”. It makes some considerations on the Community Law, providing introductory directions, conception, definition, principles and sources. It emphasizes the modalities of the origin of this juridical subject: the original Law, the derivative Law, emphasizing, regarding the last one, the creation of a new mechanism - the prejudicial re-sending.Ante a tendência, em todo o planeta, da formação de blocos regionais macroeconômicos, o conhecimento do Direito Comunitário, novo ramo do Direito, vem-se tornando necessidade não só entre os responsáveis pelo destino do projeto, como também entre os que já compreenderam que a globalização, mais do que irreversível, é ”irresistível”. Faz algumas considerações sobre o Direito Comunitário, fornecendo noções introdutórias, conceituação, definição, princípios e fontes. Destaca as modalidades das fontes desse ramo jurídico: o Direito originário, o Direito derivado, o Direito complementar e o Direito jurisprudencial, ressaltando, com relação a este último, a criação de um mecanismo inovador: o reenvio prejudicial.

    Full Text Available This paper focuses upon a place called the Vertical Village, a building in the center of Rio de Janeiro inhabited exclusively by indigenous peoples from different ethnic groups belonging to different parts of the country. In this paper, we discuss questions related to the experience of being indigenous in a city, the construction of a residential space as a village, and the constitution of indigenous identity in the urban context. Following the paths of three inhabitants of the building, the questions considered emerge from their transiting between cities and villages, frontiers either real or imaginary, prejudices and expectations of indigenous identity.

    2003-08-01

    Estrelas de Bário apresentam linhas intensas de elementos produzidos pelo processos (ex: Ba, Y, Sr, Zr) e bandas intensas de CN, C2 e CH. A hipótese mais aceita sobre a origem deste grupo peculiar é a de que essas estrelas façam parte de sistemas binários, tendo recebido material enriquecido em elementos pesados da companheira mais evoluída. Apresentamos neste trabalho uma análise detalhada de uma amostra de estrelas desta classe, incluindo determinação de parâmetros atmosféricos e cálculo de abundâncias. As temperaturas efetivas foram determinadas a partir de dados fotométricos obtidos com o Fotrap instalado no telescópio Zeiss do LNA (Laboratório Nacional de Astrofísica) (B-V, V-I, R-I, V-R), e coletados na literatura nos catálogos Hipparcos (B-V), 2MASS (Two Micron All Sky Survey) (V-K) e The General Catalogue Photometric Data (sistema Geneva). Obtivemos uma faixa de temperaturas de 4400 £ Tef £ 6500. As metalicidades foram determinadas a partir de linhas de Fe I e Fe II, estando os resultados no intervalo -1 £ [Fe/H] £ +0.1. O log g foi determinado pelo equilíbrio de ionização e pela relação com a magnitude bolométrica, a temperatura e a massa, sendo os resultados na faixa 1.5 £ log g £ 4.5. As distâncias utilizadas foram determinadas com o auxílio das paralaxes Hipparcos, e as massas determinadas por modelos de isócronas. Os espectros utilizados foram obtidos com o espectrógrafo FEROS no Telescópio de 1,5m do ESO (European Southern Observatory). As abundâncias foram calculadas por meio de síntese espectral de linhas individuais incluindo elementos alfa, pico do Fe, s e r. Encontramos um excesso de elementos pesados em relação ao Fe, como esperado para estrelas de Bário.

    Full Text Available O mapeamento geomorfológico da bacia do rio Turvo confirmou as evidências apontadas em estudos anteriores, de que a bacia apresentava feições diferentes das observadas em bacias vizinhas. Foram observadas 222 depressões fechadas em divisores de drenagem, indicando forte atuação de mecanismos geoquímicos. Por outro lado, o reduzido número de voçorocas (33 e a presença de pacotes sedimentares poucos espessos (média de 7 metros, apontam a baixa efetividade dos processos mecânicos na bacia, sobretudo ao compararmos com a sub-bacia do rio Piracema, tributária do rio Bananal, com 117 voçorocas, terraços de até 23 metros de espessura e apenas 1 depressão fechada. Internamente, a bacia do rio Turvo apresentou variações, onde, de modo geral, a sub-bacia do rio das Pedras concentrou 21 das 33 voçorocas ativas, os mais espessos pacotes fluviais e apenas 16 depressões fechadas. Assim, conclui-se que a bacia do rio Turvo é fortemente influenciada pelos processos de denudação química, e a sub-bacia do rio das Pedras apresenta as maiores características da atuação do trabalho mecânico de toda a bacia.

  10. Radionuclide Migration at the Rio Blanco Site, A Nuclear-stimulated Low-permeability Natural Gas Reservoir

    Energy Technology Data Exchange (ETDEWEB)

    Clay A. Cooper; Ming Ye; Jenny Chapman; Craig Shirley

    2005-10-01

    The U.S. Department of Energy and its predecessor agencies conducted a program in the 1960s and 1970s that evaluated technology for the nuclear stimulation of low-permeability gas reservoirs. The third and final project in the program, Project Rio Blanco, was conducted in Rio Blanco County, in northwestern Colorado. In this experiment, three 33-kiloton nuclear explosives were simultaneously detonated in a single emplacement well in the Mesaverde Group and Fort Union Formation, at depths of 1,780, 1,899, and 2,039 m below land surface on May 17, 1973. The objective of this work is to estimate lateral distances that tritium released from the detonations may have traveled in the subsurface and evaluate the possible effect of postulated natural-gas development on radionuclide migration. Other radionuclides were considered in the analysis, but the majority occur in relatively immobile forms (such as nuclear melt glass). Of the radionuclides present in the gas phase, tritium dominates in terms of quantity of radioactivity in the long term and contribution to possible whole body exposure. One simulation is performed for {sup 85}Kr, the second most abundant gaseous radionuclide produced after tritium.

    Full Text Available Rio Grande do Sul was the first Brazilian state to plant genetically modified soybean. The sowing occurred in 1998 with Roundup Ready soybean seeds from Monsanto smuggled from Argentina. The aim of this study is to investigate how this innovative process of planting transgenic soybean came about in Rio Grande do Sul based on the actor network involved in the period 1998 to 2003. Although the innovative process has been discussed in the literature on innovation management since the work of Schumpeter, there is still no clear understanding of the issues of interests and power that involve the innovative process. Given this, from within the literature we have sought a perspective that would understand the innovative process as being political. We adopted Actor Network Theory as a base for the discussion of the primary and secondary data obtained regarding the controversy surrounding transgenic soybean in RS. The results point to the existence of two translation chains that contribute towards the formation of actor networks.

Methodologically, at a theoretical level, it is, first, to problematize the very notion of citizenship. The empirical level of the research consists is the analysis of reports of free navigation on the Internet, produced during 2011, by students of Augusto Motta University Center atn(Unisuam, located in the neighborhood of Bonsucesso, periphery of Rio de Janeiro. All students involved in the study live in the suburbs or in the Baixada Fluminense. On the periphery. The original hypothesis of the research, whereby the free navigation on the Internet would not reveal any relevant form of citizen action, here identified with the universe of counter-hegemonic communication, proved to be almost entirely correct.

  17. Geomorphology of plutonium in the Northern Rio Grande

    1993-03-01

    Nearly all of the plutonium in the natural environment of the Northern Rio Grande is associated with soils and sediment, and river processes account for most of the mobility of these materials. A composite regional budget for plutonium based on multi-decadal averages for sediment and plutonium movement shows that 90 percent of the plutonium moving into the system is from atmospheric fallout. The remaining 10 percent is from releases at Los Alamos. Annual variation in plutonium flux and storage exceeds 100 percent. The contribution to the plutonium budget from Los Alamos is associated with relatively coarse sediment which often behaves as bedload in the Rio Grande. Infusion of these materials into the main stream were largest in 1951, 1952, 1957, and 1968. Because of the schedule of delivery of plutonium to Los Alamos for experimentation and weapons manufacturing, the latter two years are probably the most important. Although the Los Alamos contribution to the entire plutonium budget was relatively small, in these four critical years it constituted 71--86 percent of the plutonium in bedload immediately downstream from Otowi.

    In the scientific literature, sporotrichosis has traditionally been associated with agricultural work, since the causative agent is found naturally in the soil. However, cases have been reported recently in an urban area, related to zoonotic transmission. The current study aimed to contribute to knowledge on sporotrichosis in an urban area through an exploratory analysis of its socio-spatial distribution in Rio de Janeiro, Brazil, from 1997 to 2007, identifying the areas with the heaviest transmission. The database from the Health Surveillance Service at the Evandro Chagas Institute for Clinical Research, Oswaldo Cruz Foundation, was used to estimate incidence rates and spatial distribution. During the study period, 1,848 cases of sporotrichosis were reported, predominantly in adult women not currently in the labor market. The leading source of infection was wounds caused by domestic cats, which contributed to the spread of sporotrichosis in this urban area. Georeferencing of 1,681 cases showed a transmission belt along the border between the city of Rio de Janeiro and the adjacent municipalities in the Greater Metropolitan Area.

    Full Text Available Objectives: To analyze the data in the literature, which show a high incidence of mandibular fractures. The aim of this research was to elucidate the context in which these fractures occur among patients attended at the first aid center of “Pronto Socorro Municipal de Pelotas”, Rio Grande do Sul, Brazil. Methods: From the records referring to the period of June, 2001 to August, 2007, there were 1 345 patients with facial fractures. Of this total, 116 patients with mandibular fracture were selected for this study and the items analysed were: age, gender, mandibular fracture site, etiology and period of the year. Results: It was found that 86.2% of the sample were men. The most prevalent age was 20 to 29 years old representing 36.2%, and the most affected mandibular sites were the body, with 29 cases (25%, and the condyle, with 26 cases (22.4%. The most common cause of fractures was the physical aggression representing 37.1%. The period of the year with the highest incidence of mandibular fractures was the summer, with 38 cases (32.8%. Conclusion: It was therefore observed that the patients with mandibular fracture assisted at Pronto-Socorro Municipal de Pelotas, Rio Grande do Sul, Brazil, were generally men, 20 to 29 years old with mandibular body fracture and they were victims of physical aggression.

This work has a large thematic coherence. Throughout his poetry, prose and drama, is repeated anew the theme of Myself/Other, the desire to achieve absolute perfection, such as Icarus, and the failure of this fulfillment. In texts like the well known «Quasi» and «7» poems as well as in the «A Confissão de Lúcio» novel, it is clearly present this wish for the merge between Myself and the Other and the impossibility of achieving it. Mário de Sá-Carneiro was, together with Fernando Pessoa, one of the founders of the Portuguese Modernism and one of the directors of «Orpheu» magazine. Both poets created several important isms for the Portuguese Modermism: paulismo, interseccionismo, sensacionismo. Nevertheless they kept themselves loyal to their own styles.

  8. Reconsidering formative measurement.

    2007-06-01

    The relationship between observable responses and the latent constructs they are purported to measure has received considerable attention recently, with particular focus on what has become known as formative measurement. This alternative to reflective measurement in the area of theory-testing research is examined in the context of the potential for interpretational confounding and a construct's ability to function as a point variable within a larger model. Although these issues have been addressed in the traditional reflective measurement context, the authors suggest that they are particularly relevant in evaluating formative measurement models. On the basis of this analysis, the authors conclude that formative measurement is not an equally attractive alternative to reflective measurement and that whenever possible, in developing new measures or choosing among alternative existing measures, researchers should opt for reflective measurement. In addition, the authors provide guidelines for researchers dealing with existing formative measures. Copyright 2007 APA, all rights reserved.

    Isothermal (i.e. time dependent) martensite formation in steel was first observed in the 40ies of the XXth century and is still treated as an anomaly in the description of martensite formation which is considered as a-thermal (i.e. independent of time). Recently, the clarification of the mechanism...... of lattice strains provided fundamental information on the state of stress in the material and clarified the role of the strain energy on martensite formation. Electron backscatter diffraction revealed that the microstructure of the material and the morphology of martensite were independent on the cooling...... leading to isothermal kinetics acquired new practical relevance because of the identification of isothermal martensite formation as the most likely process responsible for enhanced performances of sub-zero Celsius treated high carbon steel products.

    This well stimulation method comprises introducing through the well bore a low-penetrating, dilatant fluid, and subjecting the fluid to sufficient pressure to produce fractures in the formation. The fluid is permitted to remain in contact with the formation so as to become diluted by the formation fluids, and thereby lose its properties of dilatancy. Also, a penetrating fluid, containing a propping agent suspended therein, in introduced into contact with the fractures at a pressure substantially reduced with respect to that pressure which would have been required, prior to the fracturing operation performed using the low-penetrating dilatant fluid. The propping agent is deposited within the fractures, and thereafter, fluid production is resumed from the fractured formation. (2 claims)

    Full Text Available This work is based on the study of the core T1 collected in the Guaratiba Mangrove, located on the northeastern margin of Sepetiba Bay. Few studies dealing with the application of benthic foraminifera to study sea level changes during the Holocene have been conducted in Sepetiba Bay, State of Rio de Janeiro, Brazil. In order to fill this gap, the core T1 was studied using textural, geochemical (carbonate, total organic carbon, total sulfur and stable isotopes evaluated in Ammonia tepida and microfaunal (benthic foraminifera data, unveiling paleoecological relationships of these organisms and the evolutionary scenario of Guaratiba Mangrove. Radiocarbon results indicate an estimated age of about 2400 yrs cal BP for the core base. Textural, geochemical and benthic foraminifera data suggest that the study area changed significantly during the last 2400 yrs cal BP. It experienced coastal waves action and shoreface processes in the period between ≈2.400-1.400 yrs cal BP; then, this phase gave place to a shallow marine environment similar to that found currently in internal and protected areas of Sepetiba Bay, between ≈1.400-350 yrs cal BP. Thenceforth, the study area evolved to the present mangrove environment. Factors related to climatic oscillations and the formation, evolution and events of rupture of Marambaia sand ridge influenced the late Holocene evolution of the northeast intertidal area of Sepetiba Bay.

    Surface water originating from the Copahue volcano crater-lake was analysed for total arsenic and four arsenic species: arsenite (iAs{sup III}), arsenate (iAs{sup V}), monomethylarsonic acid (MA{sup V}) and dimethylarsinic acid (DMA{sup V}) and other trace elements (Fe, Mn, V, Cr, Ni, Zn). A novel in-field technique for the preconcentration and separation of four arsenic species was, for the first time, used for the analysis of geothermal and volcanic waters. Total arsenic levels along the rio Agrio ranged from < 0.2-3783 {mu}g/l As{sub T}. The highest arsenic levels were recorded in the el Vertedero spring (3783 {mu}g/l As{sub T}) on the flank of the Copahue volcano, which feeds the acidic rio Agrio. Arsenite (H{sub 3}AsO{sub 3}) predominated along the upper rio Agrio (78.9-81.2% iAs{sup III}) but the species distribution changed at lago Caviahue and arsenate (H{sub 2}AsO{sub 4}{sup -}) became the main species (51.4-61.4% iAs{sup V}) up until Salto del Agrio. The change in arsenic species is potentially a result of an increase in redox potential and the formation of iron-based precipitates. Arsenic speciation showed a statistically significant correlation with redox potential (r = 0.9697, P = 0.01). Both total arsenic and arsenic speciation displayed a statistically significant correlation with vanadium levels along the river (r = 0.9961, P = 0.01 and r = 0.8488, P = 0.05, respectively). This study highlights that chemical speciation analysis of volcanic waters is important in providing ideas on potential chemical toxicity. Furthermore there is a need for further work evaluating how arsenic (and other trace elements), released in volcanic and geothermal streams/vents, impacts on both biota and humans (via exposure in thermal pools or consuming commercial drinking water). -- Highlights: Black-Right-Pointing-Pointer Application of a novel field-based method for the separation of arsenic species in a volcanic surface water system.

    Full Text Available A partir de pesquisa bibliográfica e consulta a catálogos e dicionários de filmes brasileiros, buscamos uma compreensão histórica da produção de documentários no Rio Grande do Sul, a fim de problematizar a memória deste cinema. Primeiro foi preciso existir o cinema de não-ficção no Estado, em especial o de curta-metragem, para somente mais tarde ser possível o longa-metragem de ficção gaúcho. Indicativo de que a história do cinema no Rio Grande do Sul não é uma coleção de episódios isolados, como nos fez acreditar a historiografia clássica do cinema brasileiro.

    , namely, the Rio Grande near Del Norte, CO and the Rio Hondo, Rio Chama, and Castillo Creek in NM, all tributaries of the Rio Grande basin. An additional 21 sub basins will be added as the development and testing of methods progresses. High spatial resolution Landsat TM data (30 m) are being used to evaluate estimates of snow cover maps from moderate spatial resolution data from Terra MODIS (250m and 500 m). Currently MODIS provides optimal temporal sampling (daily data) but the most effective MODIS-based snow cover mapping method has yet to be determined. We aim to identify the best MODIS snow-mapping algorithm for the Rio Grande area. For the snowmelt modeling, we are using an updated revision of SRM which directly accepts remote sensing snow cover inputs but can also automatically assess the climate change effects of future scenarios. The methods under development are intended for operational use by interested water resources agencies. With this end in mind, we will be developing an ArcGIS Toolbox (ESRI) and manual that will incorporate all the tools and instructions necessary for data download, re-projection and formatting, modeling and streamflow estimation.

    Highlights: ► The redox active N-(IDA-like)-Cu(II) monolayer is suitable for oriented and stable immobilization of His-tagged kinase Rio1. ► Cu(II) deposited onto the electrode surface play double role: immobilization sites for His-tagged proteins and transduction centres tracking the protein–small molecule interactions. ► The base of biosensor response towards target compound is the change of Rio1 conformation lading to alternation of the permeability of counter ions to Cu(II) redox centres. -- Abstract: The fabrication of electrochemical biosensor consists of the following successive steps: formation of thiol derivative of iminodiacetic acid (IDA-like/N-heterocyclic donor) and N-acetylcysteamine (NAC) self-assembled monolayer on the Au electrode, complexation of Cu(II) by N(IDA-like) attached to the surface of the Au electrode and immobilization of kinase protein Rio1 through N(IDA-like)-Cu(II)-histidine-tag covalent bond formation. Each step of modification was controlled by cyclic voltammetry, electrochemical impedance spectrometry and atomic force microscopy. The interactions between rHis 6 -Rio1 attached to the surface of the electrode and tyrphostin inhibitor (2E)-N-Benzyl-2-cyano-3-(3,4-dihydroxyphenyl)-acrylamide (AG-490) and its analogue (2-cyano-N-(4-methoxyphenyl)-3-(pyridin-3-yl)prop-2-enamide) (CPE), present in aqueous solution were monitored with Osteryoung square wave voltammetry. The basis of the biosensor response was the change in the electrochemical properties of Cu(II) redox centres upon formation of the rHis 6 -Rio1-inhibitor complex. A linear responses with high reproducibility and stability were observed between 0.10 and 0.40 μM of AG-490 as well as of CPE. The interaction between rHis 6 -Rio1 and AG-490 was stronger than the interaction with its analogue CPE. Cu(II) redox current decrease of 37.9 ± 1.6% and 23.3 ± 1.0% were observed in the presence of 0.40 μM of AG-490 and CPE, respectively. The presented biosensor could be

    It has been reported that the formation and stabilization of coastal dune fields in Brazil have a dependence on the climate changes and Relative Sea Level (RSL) variations. A few topics regarding the morphodynamics of coastal aeolian systems in Brazil can be the RSL variations in the Holocene and weather conditions. In this work, a dune field known as 'Dama Branca', located in the town of Cabo Frio, Rio de Janeiro, has been studied to understand its formation and stabilization. Dating by trapped charge dating techniques as Optically Stimulated Luminescence (OSL) using the Single Aliquot Regenerative protocol (SAR), help to understand the formation and dynamics of aeolian systems in Brazil. Samples from a dune were collected from different heights and points for dating. The results obtained by OSL-SAR showed that ages decrease as the height from the dune base increase and older samples are found in deeper horizontal positions. The ages for the base of the studied dunes indicated that its stabilization occurred during the recess of the sea level. (author)

    In this work we describe the deformation mechanisms and processes that occurred during the evolution of cataclastic deformation bands developed in the feldspar-rich conglomerates of the Rio do Peixe Basin, NE Brazil. We studied bands with different deformation intensities, ranging from single cm-thick tabular bands to more evolved clustering zones. The chemical identification of cataclastic material within deformation bands was performed using compositional mapping in SEM images, EDX and XRD analyses. Deformation processes were identified by microstructural analysis and by the quantification of comminution intensity, performed using digital image processing. The deformation bands are internally non homogeneous and developed during five evolutionary stages: (1) moderate grain size reduction, grain rotation and grain border comminution; (2) intense grain size reduction with preferential feldspar fragmentation; (3) formation of subparallel C-type slip zones; (4) formation of S-type structures, generating S-C-like fabric; and (5) formation of C‧-type slip zones, generating well-developed foliation that resembles S-C-C‧-type structures in a ductile environment. Such deformation fabric is mostly imparted by the preferential alignment of intensely comminuted feldspar fragments along thin slip zones developed within deformation bands. These processes were purely mechanical (i.e., grain crushing and reorientation). No clays or fluids were involved in such processes.

    1976-01-01

    Blister formation in metals has been observed during bombardment with inert-gas ions in the energy range between 1 and 2000 keV at doses of about 10 17 to 10 19 cm -2 . The changes in surface topography and the erosion yields were mainly studied in the scanning electron microscope (SEM). Additionally the release of the implanted gas during blister formation was observed. Recently measurements on single crystals were performed determining simultaneously the implantation profile, the total amount of trapped ions, the depth distribution of the induced lattice damage and the thickness of the covers of the blisters. In several stages of the formation process of blisters the implanted layer was observed in the transmission electron microscope (TEM) showing the formation of gas bubbles. Using the results of all these measurements in this review an attempt is made to develop a model of blister formation combining the effects of hydrostatic pressure in the gas bubbles and lateral stress due to volume swelling.

    The vascular system developed early in evolution. It is required in large multicellular organisms for the transport of nutrients, oxygen, and waste products to and from tissues. The vascular system is composed of hollow tubes, which have a high level of complexity in vertebrates. Vasculogenesis describes the de novo formation of blood vessels, e.g., aorta formation in vertebrate embryogenesis. In contrast, angiogenesis is the formation of blood vessels from preexisting ones, e.g., sprouting of intersomitic blood vessels from the aorta. Importantly, the lumen of all blood vessels in vertebrates is lined and formed by endothelial cells. In both vasculogenesis and angiogenesis, lumen formation takes place in a cord of endothelial cells. It involves a complex molecular mechanism composed of endothelial cell repulsion at the cell-cell contacts within the endothelial cell cords, junctional rearrangement, and endothelial cell shape change. As the vascular system also participates in the course of many diseases, such as cancer, stroke, and myocardial infarction, it is important to understand and make use of the molecular mechanisms of blood vessel formation to better understand and manipulate the pathomechanisms involved.

  3. Analysis of an ordinary bedload transport event in a mountain torrent (Rio Vanti, Verona, Italy)

    2016-04-01

    The correct simulation of the sediment-transport response of mountain torrents both for extreme and ordinary flood events is a fundamental step to understand the process, but also to drive proper decisions on the protection works. The objective of this research contribution is to reconstruct the 'ordinary' flood event with the associated sediment-graph of a flood that caused on the 14th of October, 2014 the formation of a little debris cone (about 200-210 m3) at the junction between the 'Rio Vanti' torrent catchment and the 'Selva di Progno' torrent (Veneto Region, Prealps, Verona, Italy). To this purpose, it is important to notice that a great part of equations developed for the computation of the bedload transport capacity, like for example that of Schoklitsch (1962) or Smart and Jaeggi (1983), are focused on extraordinary events heavily affecting the river-bed armour. These formulas do not provide reliable results if used on events, like the one under analysis, not too far from the bankfull conditions. The Rio Vanti event was characterized by a total rainfall depth of 36.2 mm and a back-calculated peak discharge of 6.12 m3/s with a return period of 1-2 years. The classical equations to assess the sediment transport capacity overestimate the total volume of the event of several orders of magnitude. By the consequence, the following experimental bedload transport equation has been applied (D'Agostino and Lenzi, 1999), which is valid for ordinary flood events (q: unit water discharge; qc: unit discharge of bedload transport initiation; qs: unit bedload rate; S: thalweg slope): -qs-˜= 0,04ṡ(q- qc) S3/2 In particular, starting from the real rainfall data, the hydrograph and the sediment-graph have been reconstructed. Then, comparing the total volume calculated via the above cited equation to the real volume estimated using DoD techniques on post-event photogrammetric survey, a very satisfactory agreement has been obtained. The result further supports the thesis

    Background The burden of HIV in transgender women (transwomen) in Brazil remains unknown. We aimed to estimate HIV prevalence among transwomen, and identify the factors associated with newly diagnosed HIV infections. Methods “Transcender” was a respondent driven sampling study of transwomen in Rio de Janeiro, Brazil, conducted from August 2015 to January 2016. Twelve seeds were recruited from social movements and formative phase. Eligibility criteria were: self-identification as transwomen, being 18 years of age or older, living in Rio de Janeiro or metropolitan area, and having a valid peer recruitment coupon. Participants were categorized as HIV-negative, known HIV infected, or newly diagnosed as HIV infected. Predictors of newly diagnosed HIV infections were assessed by comparing the newly diagnosed with the HIV-negative. Population estimates were adjusted using the RDSII estimator. Findings In total, 345 eligible transwomen were enrolled. The study sample was young and diverse on gender identity. Population estimates of no prior HIV testing, HIV-infection and newly diagnosed as HIV-infected were 29·1%, 32·1% and 7·0%, respectively (based on n=60 with no prior testing, n=141 HIV-infected, n=40 newly diagnosed). Syphilis, rectal chlamydia and gonorrhea infection were diagnosed in 28·9%, 14·6%, and 13·5%, respectively. Newly diagnosed HIV infections were associated with black race (22·8; 95%CI 2·9–178·9), travesti (34·1; 95%CI 5·8–200·2) or transsexual woman (41·3; 95%CI 6·3–271·2) gender identity, history of sex work (30·7; 95%CI 3·5–267·3), and history of sniffing cocaine (4·4; 95%CI 1·4–14·1). Interpretation Our results suggest that transwomen bear the largest burden of HIV among any population at risk in Brazil. The high proportion of HIV diagnosis among young participants points to the need for tailored long-term health care and prevention services in order to curb the HIV epidemic and improve the quality-of-life of

    The Neoarchean Rio das Velhas and Pitangui greenstone belts are situated in the southern São Francisco Craton, Minas Gerais, Brazil. These greenstone belts were formed between ca. 2.79-2.73 Ga, and consist mostly of mafic to ultramafic volcanics and clastic sediments, with minor chemical sediments and felsic volcanics that were metamorphosed under greenschist facies. Komatiites are found only in the Rio das Velhas greenstone belt, which is composed of high-MgO volcanic rocks that have been identified as komatiites and high-Mg basalts, based on their distinctive geochemical characteristics. The Rio das Velhas komatiites are composed of tremolite + actinolite + serpentine + albite with a relict spinifex-texture. The Rio das Velhas komatiites have a high magnesium content ((MgO)adj ≥ 28 wt.%), an Al-undepleted Munro-type [(Al2O3/TiO2)adj and (CaO/Al2O3)adj] ratio ranging from 27 to 47 and 0.48 to 0.89, relatively low abundances of incompatible elements, a depletion of light rare earth elements (LREE), a pattern of non-fractionated heavy rare- earth elements (HREE), and a low (Gd/Yb)PM ratio (≤ 1.0). Negative Ce anomalies suggest that alteration occurred during greenschist facies metamorphism for the komatiites and high-Mg basalts. The low [(Gd/Yb)PM 18] and high HREE, Y, and Zr content suggest that the Rio das Velhas komatiites were derived from the shallow upper mantle without garnet involvement in the residue. The chemical compositions [(Al2O3/TiO2)adj, (FeO)adj, (MgO)adj, (CaO/Al2O3)adj, Na, Th, Ta, Ni, Cr, Zr, Y, Hf, and REE] indicate that the formation of the komatiites, high-Mg basalts and basalts occurred at different depths and temperatures in a heterogeneous mantle. The komatiites and high-Mg basalts melted at liquidus temperatures of 1450-1550 °C. The Pitangui basalts are enriched in the highly incompatible LILE (large-ion lithophile elements) relative to the moderately incompatible HFS (high field strength) elements. The Zr/Th ratio ranging from 76 to

    Preliminary results of a research carried out at the Complejo Rio Blanco de Ullum, San Juan. Argentina are summarized in the present paper. These studies are focused on geological and metallogenic features o f this unit. The study area is located 20 km. WNW of San Juan city with geographic coordinates of 31grades 30' South latitude and 68 grades 52' West longitude. The older rocks aotcroping in the area correspond to limestones of Ordovician San Juan Formation, the chronologic succession continues with sales and siltstones of Silurian Tambolar Formation, pelites and subgraywackes of Devonian Punta Negra Formation and finally a 1500 m thick package of piroclastics and sediments of Albarracin Formation of Tertiary age. Albarracin Formation is composed pf a Basal Member (sandstones and stilstones), a Tuffaceous Member (tuffs, tuffites and oligomictic breccia s with conglomerate interbed dings in the upper part) and a Conglomeratic Member (polimictic para conglomerates). According to piroclastics facies, relationships and spreading area of piroclastics deposits a c olapsed dome and avalanche model is proposed to be the main process for the piroclastics package outcropping in the area.Sedimentary and piroclastics rocks are intruded by five sub volcanic units as noted by Leveratto (1968) which are composed by different lithologies such as: Altered Da cite - Rhyolite, Ullum Da cite, Cerro Blanco de Zonda Andesite, Ullum Andesite and Hybrid Andesite.Detailed work on alteration assemblages and metallogenic features in the southwestern sector of the Complejo resulted in the identification of three alteration zones with characteric features of potassic, argillic and propyllitic signature.

    Full Text Available Este artigo discute um folhetim jornalístico do escritor austríaco Joseph Roth que trata de uma miniatura do Templo de Salomão, encontrada por ele num café da Hirtenstrasse berlinense, no coração do que foi, na década de 1920, o bairro habitado pelos judeus do Leste da Europa na capital alemã. A nostalgia, sob cujo signo foi criada tal miniatura, torna-se uma metáfora da nostalgia pelo império Austro-Húngaro, chave para a compreensão da obra romanesca deste escritor. Ao mesmo tempo, esta nostalgia rothiana é contextualizada no âmbito das crenças místicas e messiânicas do judaísmo tradicional.

    2016-06-01

    Full Text Available By looking at the growth of rap and favela funk as it begins to acquire visibility among the Brazilian middle class in Rio de Janeiro, this article analyzes black women performers of funk and rap who have negotiated the use of the pejorative depictions of women inherent to the genre to express a type of empowerment. Exploring the transitions between generations of feminist thought and practice, I explore the resonance of gender ideologies with working-class and racialized women rap and funk performers. The article emphasizes the importance of these performers for voice and visibility, preparing the stage for a fourth wave of feminism erupting through but transcending lipstick, libido and microphones

    Full Text Available INTRODUÇÃO: O treinamento desportivo em diversas modalidades está associado à presença de lesões, principalmente quando apresenta grande volume e intensidade. Poucos estudos nacionais investigaram a prevalência de lesão em tenistas, porém, as informações sobre a localização, o tipo e o mecanismo das lesões que acometem esse grupo de atletas são importantes para a prevenção e o tratamento de tais lesões. OBJETIVO: Verificar a frequência de lesão relatada por tenistas amadores no município do Rio de Janeiro. MÉTODOS: A avaliação foi realizada por meio de um questionário estruturado, com informações sobre a região corporal acometida, tipo e mecanismo de lesão, além de dados sobre a característica do treinamento. Os grupos formados, lesão e não lesão, foram comparados pelo teste t de Student ou Mann-Whitney e pelo teste Qui-quadrado ou Exato de Fisher, no programa SPSS (p<0,05. RESULTADOS: Dos 159 jogadores de tênis (89,3% homens; 45,3 ± 11,4 anos de idade; 8,5 ± 6,6 anos de prática esportiva que responderam o questionário, 38,4% relataram já ter sido acometidos por alguma lesão decorrente do tênis. As regiões mais acometidas foram: cotovelo (24,5%, joelho (11,3% e tornozelo (6,9%. Considerando todas as lesões, a tendinite foi o tipo mais relatado (24,5%, seguido por entorse (12,6% e lesão meniscal (4,4%. Com relação ao mecanismo de lesão, os mais prevalentes foram por repetição (25,2% e mudança de direção (15,1%. O grupo lesão apresentou maiores valores para idade (48,8 ± 10,1 vs. 43,6 ± 11,8 anos, tempo de prática da modalidade (10,5 ± 8,5 vs. 7,2 ± 4,8 anos e massa corporal total (86,8 ± 9,8 vs. 81,0 ± 11,0 kg. CONCLUSÃO: A prevalência de lesão em tenistas amadores no Rio de Janeiro foi de 38,4%, sendo a epicondilite lateral do cotovelo a mais frequente, em virtude da repetição do gesto esportivo.

  12. Investigating the role of RIO protein kinases in Caenorhabditis elegans.

    Directory of Open Access Journals (Sweden)

    Tasha K Mendes

    Full Text Available RIO protein kinases (RIOKs are a relatively conserved family of enzymes implicated in cell cycle control and ribosomal RNA processing. Despite their functional importance, they remain a poorly understood group of kinases in multicellular organisms. Here, we show that the C. elegans genome contains one member of each of the three RIOK sub-families and that each of the genes coding for them has a unique tissue expression pattern. Our analysis showed that the gene encoding RIOK-1 (riok-1 was broadly and strongly expressed. Interestingly, the intestinal expression of riok-1 was dependent upon two putative binding sites for the oxidative and xenobiotic stress response transcription factor SKN-1. RNA interference (RNAi-mediated knock down of riok-1 resulted in germline defects, including defects in germ line stem cell proliferation, oocyte maturation and the production of endomitotic oocytes. Taken together, our findings indicate new functions for RIOK-1 in post mitotic tissues and in reproduction.

    A radioisotope production laboratory has been installed at Instituto de Engenharia Nuclear in Rio de Janeiro. It is intended primarily for processing short-lived radioisotopes produced by a multiparticle, variable energy, isochronous, compact CV-28 Cyclotron and for preparation of radiopharmaceuticals and labelled molecules. Carrier-free iodine-123, indium-111, thalium-201, bromine-77 and gallium-67 with high purity have been produced. An irradiated target transport system has been built. Special targets that can dissipate high surface power densities are being developed. Each radioisotope is processed in a remotely controlled cell equiped with electric and pneumatic systems as well as manipulators ans tongs. Quality control is achieved by atomic absorption spectrophotometry, spot tests, gamma-ray spectroscopy and thin-layer chromatography. Biological tests in mice have confirmed the good quality of the radiopharmaceuticals. (Author) [pt

    We have worked with elementary and middle school teachers in the Rio Grande Valley for the last 10 years bringing Earth and Space Science themed workshops to underserved areas of Texas. The Texas curriculum was also changed to include Astronomy and Space Science requirement in the tests students need to take to prove their academic preparedness. The teachers worked through a variety of inquiry-based, hands-on activities after a short presentation on the background science. In order to evaluate our effectiveness, we have asked the teachers to take pre- and post-workshop tests, and we asked them to fill out a self-reflective survey. We will report on our experiences, what works best with the teachers, and in what areas we still have a long way to go.This work was supported by various NASA education grants and Cooperative agreements, as well as grants provided by the Texas Space Grant Consortium.

    We show that in a standardized in vitro flow system unencapsulated variants of genetically diverse lineages of Neisseria meningitidis formed biofilms, that could be maintained for more than 96 h. Biofilm cells were resistant to penicillin, but not to rifampin or ciprofloxacin. For some strains......, microcolony formation within biofilms was observed. Microcolony formation in strain MC58 depended on a functional copy of the pilE gene encoding the pilus subunit pilin, and was associated with twitching of cells. Nevertheless, unpiliated pilE mutants formed biofilms showing that attachment and accumulation......X alleles was identified among genetically diverse meningococcal strains. PilX alleles differed in their propensity to support autoaggregation of cells in suspension, but not in their ability to support microcolony formation within biofilms in the continuous flow system....

    1995-01-01

    When nitrogen was selected as the glovebox atmosphere for the Replacement Tritium Facility (RTF) at the Savannah River Site (SRS), a concern was raised as to the possibility of tritiated ammonia formation in the gloveboxes. Experimental data were produced to study the tritiated ammonia formation rate in a tritium and nitrogen mixture. A rate equation that closely simulates the experimental data was developed. This rate equation can be used to calculate the formation of tritiated ammonia from different concentrations of tritium and nitrogen. The reaction of T 2 and N 2 to form NT 3 is a slow process, particularly when the tritium concentration is low. The reaction requires weeks or months to reach radiochemical equilibrium dependent on the concentrations of the reactants. 4 refs., 6 figs., 1 tab

    2010-01-01

    The rapidly expanding field of galaxy formation lies at the interface between astronomy, particle physics, and cosmology. Covering diverse topics from these disciplines, all of which are needed to understand how galaxies form and evolve, this book is ideal for researchers entering the field. Individual chapters explore the evolution of the Universe as a whole and its particle and radiation content; linear and nonlinear growth of cosmic structure; processes affecting the gaseous and dark matter components of galaxies and their stellar populations; the formation of spiral and elliptical galaxies; central supermassive black holes and the activity associated with them; galaxy interactions; and the intergalactic medium. Emphasizing both observational and theoretical aspects, this book provides a coherent introduction for astronomers, cosmologists, and astroparticle physicists to the broad range of science underlying the formation and evolution of galaxies.

    Planets form in gaseous protoplanetary disks surrounding newborn stars. As such, the most direct way to learn how they form from observations, is to directly watch them forming in disks. In the past, this was very difficult due to a lack of observational capabilities; as such, planet formation was largely a subject of pure theoretical astrophysics. Now, thanks to a fleet of new instruments with unprecedented resolving power that have come online recently, we have just started to unveil features in resolve images of protoplanetary disks, such as gaps and spiral arms, that are most likely associated with embedded (unseen) planets. By comparing observations with theoretical models of planet-disk interactions, the masses and orbits of these still forming planets may be constrained. Such planets may help us to directly test various planet formation models. This marks the onset of a new field — observational planet formation. I will introduce the current status of this field.

    Full Text Available Oxides containing aluminium and barium, optionally with chromium, are refractory with several possible industrial uses. A gel precursor of an oxide having the formula BaO.n(Al2xCr2yO3, where 1Oxidos contendo alumínio e bário, opcionalmente com crômio, são refratários com vários possíveis usos industriais. Foi preparado um gel precursor de um óxido de formula BaO.n(Al2xCr2yO3, com 1rio com uma solução de um sal de bário com solução de um sal de alumínio ou uma solução de um sal de alumínio e um sal de cromo III, formando então um gel que é queimado para se obter o óxido desejado. Filamentos podem ser estraídos duramente a formação do gel ou extrudados de um gel semi-rígido. Estudos de infravermelho com transformada de Fourier, difração de raios X e ressonância magnética nuclear com 27AL mostraram que o bário não é incorporado diretamente na estrutura do gel. Oxidos de alumínio e bário foram obtidos somente após liquefação de espécies de bário. Foi preparada uma mistura de pós adequada para queima para se obter um óxido de fórmula BaO.m[Al2x Cr2y O3] com 4,6rio, óxido de bário, carbonato de bário e mono-aluminato de bário, alumina e/ou alumina hidratada e óxido de cromo III, com quantidades relativas variando para se obter na queima valores desejados de m e de y. Corpos cerâmicos resistentes da fórmula BaO 6 Al2O3 (m=6 e y=0 foram preparados. Estudos de difração de raios X de óxidos de composições (n ou m=6 e y=0 sinterizados em alta temperatura mostraram que mono-aluminato de bário é uma fase intermediária de baixa temperatura. Cromo III reduz a temperatura necessária para formar um óxido de alumínio e bário. É feito um sumário de trabalhos anteriormente publicados.

    Full Text Available This paper proposes to discuss the transformation of urban landscapes in the Paraíba River Valley as members of the coffee elite emerged in this area and a specific landscape configuration was projected there based on the use of imperial palms ( Roystonea oleracea. Chronologically speaking, the paper covers a period from 1808 to 1911; with regard to space, it focuses on the stretch between Rio de Janeiro and São Paulo, with a closer look at the case of the city of Lorena (SP, so as to encompass all the changes that took place in this region from the introduction to the decline of coffee growing as an economic activity. The urban changes during this period were accompanied by the advent and consolidation of landscapes typical of the society of coffee growers: streets lined with palm trees, a token of their close connections with the royal court, a display of their adherence to “Frenchified customs”. Such configurations were used to characterize public areas and raise them to the same status as the new buildings that gradually replaced those built in colonial style. The paper is structured around three key moments, namely: the introduction of imperial palms in Rio de Janeiro and their association with the idea of nobility and rank, and consequently with neoclassical architecture, which was brought to the colony by the 1816 French Mission; the dissemination of the use of imperial palms as a landscaping resource typical of public spaces from the royal court to the capital of São Paulo, particularly by the coffee barons during the second period of monarchic rule; and, finally, the hypothesis that the use of imperial palms to embellish public areas in São Paulo may have been introduced by a Lorena citizen associated with the coffee elite, albeit later, when Brazil was already a republic

    2003-10-01

    Full Text Available Dengue fever is currently the most important arthropod-borne viral disease in Brazil. Mathematical modeling of disease dynamics is a very useful tool for the evaluation of control measures. To be used in decision-making, however, a mathematical model must be carefully parameterized and validated with epidemiological and entomological data. In this work, we developed a simple dengue model to answer three questions: (i which parameters are worth pursuing in the field in order to develop a dengue transmission model for Brazilian cities; (ii how vector density spatial heterogeneity influences control efforts; (iii with a degree of uncertainty, what is the invasion potential of dengue virus type 4 (DEN-4 in Rio de Janeiro city. Our model consists of an expression for the basic reproductive number (R0 that incorporates vector density spatial heterogeneity. To deal with the uncertainty regarding parameter values, we parameterized the model using a priori probability density functions covering a range of plausible values for each parameter. Using the Latin Hypercube Sampling procedure, values for the parameters were generated. We conclude that, even in the presence of vector spatial heterogeneity, the two most important entomological parameters to be estimated in the field are the mortality rate and the extrinsic incubation period. The spatial heterogeneity of the vector population increases the risk of epidemics and makes the control strategies more complex. At last, we conclude that Rio de Janeiro is at risk of a DEN-4 invasion. Finally, we stress the point that epidemiologists, mathematicians, and entomologists need to interact more to find better approaches to the measuring and interpretation of the transmission dynamics of arthropod-borne diseases.

    Guanabara Bay is the second largest bay in the coast of Brazil, with an area of 384 km2. In its surroundings live circa 16 million inhabitants, out of which 6 million live in Rio de Janeiro city, one of the largest cities of the country, and the host of the 2016 Olympic Games. Anthropogenic interference in Guanabara Bay area started early in the XVI century, but environmental impacts escalated from 1930, when this region underwent an industrialization process. Herein we present an overview of the current environmental and sanitary conditions of Guanabara Bay, a consequence of all these decades of impacts. We will focus on microbial communities, how they may affect higher trophic levels of the aquatic community and also human health. The anthropogenic impacts in the bay are flagged by heavy eutrophication and by the emergence of pathogenic microorganisms that are either carried by domestic and/or hospital waste (e.g., virus, KPC-producing bacteria, and fecal coliforms), or that proliferate in such conditions (e.g., vibrios). Antibiotic resistance genes are commonly found in metagenomes of Guanabara Bay planktonic microorganisms. Furthermore, eutrophication results in recurrent algal blooms, with signs of a shift toward flagellated, mixotrophic groups, including several potentially harmful species. A recent large-scale fish kill episode, and a long trend decrease in fish stocks also reflects the bay’s degraded water quality. Although pollution of Guanabara Bay is not a recent problem, the hosting of the 2016 Olympic Games propelled the government to launch a series of plans to restore the bay’s water quality. If all plans are fully implemented, the restoration of Guanabara Bay and its shores may be one of the best legacies of the Olympic Games in Rio de Janeiro. PMID:26635734

    JAS. Figueiredo

    Full Text Available The Rio dos Sinos watershed is located in the eastern region of the state of Rio Grande do Sul and includes 32municipalities. These municipalities develop several different economic activities such as farming and livestock along the 190 km length of the Rio dos Sinos, one of the rivers with the worst quality of water in Brazil. The region is also characterised by growing urbanisation and heavy industrialisation. The main economic activity is the leather and footwear industry. This diversified land use puts the Rio dos Sinos watershed at risk of a wide range of potential environmental impacts. The aim of the present article is to discuss the socioeconomic process currently implemented in the Rio dos Sinos watershed and the effect of these human actions on the environmental quality described throughout this special issue of the Brazilian Journal of Biology.

    Konrad Kubiński

    2017-02-01

    Full Text Available The atypical kinase Rio1 is widespread in many organisms, ranging from Archaebacteria to humans, and is an essential factor in ribosome biogenesis. Little is known about the protein substrates of the enzyme and small-molecule inhibitors of the kinase. Protein kinase CK2 was the first interaction partner of Rio1, identified in yeast cells. The enzyme from various sources undergoes CK2-mediated phosphorylation at several sites and this modification regulates the activity of Rio1. The aim of this review is to present studies of the relationship between the two different kinases, with respect to CK2-mediated phosphorylation of Rio1, regulation of Rio1 activity, and similar susceptibility of the kinases to benzimidazole inhibitors.

  13. Planetesimals and Planet Formation

    Science.gov (United States)

    Chambers, John

    The first step in the standard model for planet formation is the growth of gravitationally bound bodies called ``planetesimals'' from dust grains in a protoplanetary disk. Currently, we do not know how planetesimals form, how long they take to form, or what their sizes and mechanical properties are. The goal of this proposal is to assess how these uncertainties affect subsequent stages of planetary growth and the kind of planetary systems that form. The work will address three particular questions: (i) Can the properties of small body populations in the modern Solar System constrain the properties of planetesimals? (ii) How do the properties of planetesimals affect the formation of giant planets? (iii) How does the presence of a water ice condensation front (the ``snow line'') in a disk affect planetesimal formation and the later stages of planetary growth? These questions will be examined with computer simulations of planet formation using new computer codes to be developed as part of the proposal. The first question will be addressed using a statistical model for planetesimal coagulation and fragmentation. This code will be merged with the proposer's Mercury N-body integrator code to model the dynamics of large protoplanets in order to address the second question. Finally, a self- consistent model of disk evolution and the radial transport of water ice and vapour will be added to examine the third question. A theoretical understanding of how planets form is one of the key goals of NASA and the Origins of Solar Systems programme. Researchers have carried out many studies designed to address this goal, but the questions of how planetesimals form and how their properties affect planet formation have received relatively little attention. The proposed work will help address these unsolved questions, and place other research in context by assessing the importance of planetesimal origins and properties for planet formation.

    The spatial distribution of Galaxies and Galaxy congestions in the southern galactic hemisphere is studied. The rich galaxy congestions, containing many elliptic Galaxies and radiogalaxies, are linked with each other by chains of scanty congestions with moderate content of elliptic Galaxies and radiogalaxies. The flat formation, linking the density pikes and the intermediate chains, can reasonably be called supercongestion. In the central region of supercongestions there is a thin layer of Galaxies consisting of only spiral Galaxies. The neighbouring supercongestions touch each other, while the intersupercongestion space contains no Galaxy congestions and almost no Galaxies. It is shown that such a structure was, apparently, formed before the formation of Galaxies

    The present theories of galaxy formation are reviewed. The relation between peculiar velocities and the correlation function of galaxies points to the possibility that galaxies do not form uniformly everywhere. Scale invariant properties of the cluster-cluster correlations are discussed. Comparing the correlation functions in a dimensionless way, galaxies appear to be stronger clustered, in contrast with the comparison of the dimensional amplitudes of the correlation functions. Theoretical implications of several observations as Lyman-α clouds, correlations of faint galaxies are discussed.

    Stahler, Steven W

    2008-01-01

    This book is a comprehensive treatment of star formation, one of the most active fields of modern astronomy. The reader is guided through the subject in a logically compelling manner. Starting from a general description of stars and interstellar clouds, the authors delineate the earliest phases of stellar evolution. They discuss formation activity not only in the Milky Way, but also in other galaxies, both now and in the remote past. Theory and observation are thoroughly integrated, with the aid of numerous figures and images. In summary, this volume is an invaluable resource, both as a text f

    Full Text Available A evolução urbana do município do Rio de Janeiro durante o século XX, especialmente a partir da sua segunda metade, é fortemente marcada por crescentes privilégios concedidos ao crescimento da utilização dos meios de transporte de massa e, principalmente, individuais, feitos por veículos a motor de explosão. Uma das conseqüências desta política é a ascenção da mortalidade por acidentes de trânsito, verificada durante a década de 80, entre homens e mulheres de todas as idades. Neste trabalho demonstra-se também que, em 1990, apenas cerca de 1/3 das vítimas fatais nos acidentes de trânsito estavam "embarcadas" nos veículos. Portanto, a maioria dos óbitos por este tipo de acidente, cerca de 2/3, ocorreu por atropelamentos. Isto indica a necessidade de o poder público reverter a prioridade na prevenção das mortes por acidentes de trânsito em favor de medidas eficazes que protejam os pedestres.The evolution of the city of Rio de Janeiro during the 20th century, particularly since 1950, has been strongly characterized by increasing concession of privileges for the use of motor vehicles for both mass (and especially individual transportation. One of the main consequences of this policy was a rising mortality rate due to traffic accidents during the 1980s, among men and women of all ages. This paper demonstrates that in 1990 only about one-third of the fatal victims of traffic accidents were inside the vehicles involved. In Rio de Janeiro, the majority of deaths from this kind of accident (approximately two-thirds were pedestrians. Thus, policies aimed at reducing traffic-related mortality should give priority to the protection of pedestrians rather than drivers.

    We present new U-Pb zircon ages and Sm-Nd-Pb isotopic data for volcanic and hypabyssal acid rocks from the northernmost exposure of the Acampamento Velho Formation in the NW portion of the Sul-Rio-Grandense Shield, Brazil. The first volcanic episode, grouped in the high-Ti rhyolites from the Tupanci hill, shows age of 579 ± 5.6 Ma, which is in agreement with the post-collisional Acampamento Velho Formation volcanism in the Bom Jardim Group of the Camaquã Basin. A poorly constrained age of 558+/- 39Ma was obtained for rhyolites from the low-Ti group at the Picados Hill, which may indicate a younger acid volcanism, or a greater time span for the volcanism of the Acampamento Velho Formation in southernmost Brazil. Regarding magmatic sources, Sm/Nd isotopic data coupled to Pb isotopes and a review of trace element geochemistry indicate different amounts of Paleoproterozoic (Dom Feliciano, Pinheiro Machado Suite) to Neoproterozoic (Rio Vacacaí terrane) lower crust melting. Our data, coupled with literature data, contribute to a better understanding of the stratigraphic evolution for the Neoproterozoic post-collisional volcanic successions of the Camaquã Basin in the Sul-Rio-Grandense Shield.

    The solution for electrostatic potential within a simply modeled tandem mirror thermal barrier is seen to exhibit a sheath at each edge of the cell. The formation of the sheath requires ion collisionality and the analysis assmes that the collisional trapping rate into the barrier is considerably slower than the barrier pump rate

  2. Formation of topological defects

    International Nuclear Information System (INIS)

    Vachaspati, T.

    1991-01-01

    We consider the formation of point and line topological defects (monopoles and strings) from a general point of view by allowing the probability of formation of a defect to vary. To investigate the statistical properties of the defects at formation we give qualitative arguments that are independent of any particular model in which such defects occur. These arguments are substantiated by numerical results in the case of strings and for monopoles in two dimensions. We find that the network of strings at formation undergoes a transition at a certain critical density below which there are no infinite strings and the closed-string (loop) distribution is exponentially suppressed at large lengths. The results are contrasted with the results of statistical arguments applied to a box of strings in dynamical equilibrium. We argue that if point defects were to form with smaller probability, the distance between monopoles and antimonopoles would decrease while the monopole-to-monopole distance would increase. We find that monopoles are always paired with antimonopoles but the pairing becomes clean only when the number density of defects is small. A similar reasoning would also apply to other defects

    Chlorination is the most important method of disinfection in Malaysia which aims at ensuring an acceptable and safe drinking water quality. The dosing of chlorine to surface water containing ammonia and nitrogen compounds may form chloramines in the treated water. During this reaction, inorganic and organic chloramines are formed. The recommended maximum acceptable concentration (MAC) for chloramines in drinking water is 3000 μg/L. The production of monochloramine, dichloramine and trichloramine is highly dependent upon pH, contact time and the chlorine to ammonia molar ratio. The purpose of this study is to examine the formation of chloramines that occur upon the chlorination during the treatment process. Chloramines were determined using the N,N-diethyl-p-phenylenediamine (DPD) colorimetric method. The influences of ammonia, pH and chlorine dosage on the chloramines formation were also studied. This paper presents a modeling approach based on regression analysis which is designed to estimate the formation of chloramines. The correlation between the concentration of chloramines and the ammonia, pH and chlorine dosage was examined. In all cases, the quantity of chloramines formed depended linearly upon the amount of chlorine dosage. On the basis of this study it reveals that the concentration of chloramines is a function of chlorine dosage and the ammonia concentration to the chlorination process. PH seems to not significantly affect the formation of chloramines. (author)

    Leung, P.; Wong, A.Y.; Quon, B.H.

    1981-01-01

    Experiments on both stationary and propagating double layers and a related analytical model are described. Stationary double layers were produced in a multiple plasma device, in which an electron drift current was present. An investigation of the plasma parameters for the stable double layer condition is described. The particle distribution in the stable double layer establishes a potential profile, which creates electron and ion beams that excite plasma instabilities. The measured characteristics of the instabilities are consistent with the existence of the double layer. Propagating double layers are formed when the initial electron drift current is large. Ths slopes of the transition region increase as they propagate. A physical model for the formation of a double layer in the experimental device is described. This model explains the formation of the low potential region on the basis of the space charge. This space charge is created by the electron drift current. The model also accounts for the role of ions in double layer formation and explains the formation of moving double layers. (Auth.)

    In this study, bronze samples (94.059% Cu; 0.023% Zn; 0.077% Pb and 5.801% Sn, w/w) were exposed for 8 months to a marine atmosphere (splash zone) at Barra of Tijuca Beach, Rio de Janeiro. X-ray diffraction analysis (XRD) was used to identify the composition of the corrosion products formed on the samples. The electrochemical properties were analyzed using potential and electrochemical impedance measurements. These analyses and measurements were obtained from periodically removed samples, and compared to those exposed to laboratory tests (total and alternating immersion) in 10 -2 mol L -1 NaCl solution. The corrosion potential results, allied to XRD analysis, showed that the chemical nature of the films obtained on the surface of the field test samples was very similar to that obtained in the alternating immersion test. The main products identified were cuprite and atacamite. However, the film formed during the total immersion (TI) test was primarily composed of cuprite with nantokite traces, which was not observed in either the field or in alternating tests. The electrochemical impedance measurements obtained in laboratory and field test samples showed the formation of films with a porous structure. The thermodynamic evaluation was also consistent with the corrosion products formed.

    Full Text Available The formation of life competences is the result of a quality education that prepares students to meet the challenges of a fast moving world where equality and equal opportunities should constitute premises of education; training them is a challenge teachers to assume new generations contribute actively to a better world. In Cuba are important research on the formation of communication competences and self-regulated learning in primary school. The paper shows the result of an investigation that provides a methodology for the formation of life competences in primary school education, used as an essential pathway research activity. The methodological approach of research has a quantitative approach and an explanatory scope to establish and make sense of understanding the causal relationship between the direction of research activity and training of life competences. Theoretical, empirical and mathematical-statistical, for characterizing the initial state, processing of results and analysis: research methods are used. The application of the methodology for the formation of life competences makes teachers lead the teaching-learning process with a research and transforming teaching concept, where the school is the protagonist of their learning and causes changes in their performances, which are evident in the formed competences related to effective and affective communication; the solution of problems related to life; the use of means in obtaining the knowledge and the expression of a behavior consistent with school and social demands. The effectiveness of the methodology confirms that there is a causal relationship between the direction of research activity by teachers and the formation of life competences in school.

  13. Medusae Fossae Formation

    2002-01-01

    (Released 10 April 2002) The Science This THEMIS visible image was acquired near 7o S, 172o W (188o E) and shows a remarkable martian geologic deposit known as the Medusae Fossae Formation. This Formation, seen here as the raised plateau in the upper two-thirds of the image, is a soft, easily eroded deposit that extends for nearly 1,000 km along the equator of Mars. In this region the deposit has been heavily eroded by the wind to produce a series of linear ridges called yardangs. These parallel ridges point in direction of the prevailing winds that carved them, and demonstrate the power of martian winds to sculpt the dry landscape of Mars. The Medusae Fossae Formation has been completely stripped from the surface in the lower third of the image, revealing a harder layer below that is more resistant to wind erosion. The easily eroded nature of the Medusae Fossae Formation suggests that it is composed of weakly cemented particles, and was most likely formed by the deposition of wind-blown dust or volcanic ash. Several ancient craters that were once completely buried by this deposit are being exposed, or exhumed, as the overlying Medusae Formation is removed. Very few impact craters are visible on this Formation, indicating that the surface seen today is relatively young, and that the processes of erosion are likely to be actively occurring. The Story Medusa of Greek mythology fame, the name-giver to this region, had snaky locks of hair that could turn a person to stone. Wild and unruly, this monster of the underworld could certainly wreak havoc on the world of the human imagination. As scary as she was, Medusa would have no advantage over the fierce, masterful winds blowing across Mars, which once carved the streaky, terrain at the top of this image. Wild and whipping, these winds have slowly eroded away the 'topsoil,' revealing ancient craters and other surface features they once covered. The loosely cemented particles of this 'topsoil' are likely made up of dust

Participaram da pesquisa sessenta universitários do Rio de Janeiro, de ambos os sexos, entre 17 e 30 anos. Utilizamos um questionário com perguntas abertas, no qual eles apresentaram seus familiares. O material obtido foi analisado em termos temáticos e estatísticos. Entre os usuários de maconha, prevaleceu a autoridade e a ênfase nos papéis sociais, sendo a interação familiar marcada pelo acento emocional e pela idealização. Entre os não-usuários a autoridade coexistiu com relações interpessoais de companheirismo e partilha, num contexto familiar em que predominaram não aspectos afetivos mas práticas de proteção e cuidados. Podemos afirmar que o papel da família na prevenção ao uso de drogas está associado à promoção da autonomia, diferenciação e garantia de um espaço próprio para o jovem.The objective of this paper was to study the family context among marijuana users and non-users. Moscovici's theory of social representations, as well as some considerations from Becker and Foucault, was used as theoretical basis for data analysis.

Longe, entretanto, de apoiar-se nessas conclusões, o documento inicial para a Rio+20 preconiza como solução para os grandes problemas socioambientais contemporâneos o aprofundamento daquilo que já vem sendo feito: ampliar o combate à pobreza e aprofundar a cooperação internacional em direção à ecoeficiência. Este trabalho procura mostrar que são significativas as conquistas dos últimos vinte anos nessas duas direções. Mas não há condições materiais de persistir no sucesso da luta contra a pobreza caso se perpetue a ilusão de que a desigualdade deve ser enfrentada sem que se altere o poder sobre os recursos ecossistêmicos dos que se encontram nos andares de cima da pirâmide social.Many studies published last year (including some organized by the United Nations show that the world economic system has dangerously passed over the ecossytemic frontiers, mainly in climate, biodiversity and nitrogen cycle concerns. Far from using these data and conclusions, the Rio+20 zero-draft envisions a business as usual solution to the socioenvironmental contemporary problems: strengthen poverty fighting and deepen international cooperation toward eco-efficiency. This paper recognizes the huge conquest made in these two domains over the last twenty years. But there are no material conditions for success reducing poverty if the illusion that inequality can be fought without altering the power over natural resources that have those who occupy the upper positions of the social pyramid remains.

    Full Text Available A anemia falciforme tem um desenvolvimento clínico extremamente variável que se caracteriza principalmente por diferentes graus de intensidade da anemia hemolítica. As razões dessa variabilidade são parcialmente conhecidas na expressão fenotípica da doença. Apesar de ter um mesmo defeito genético, a anemia falciforme pode estar associada com níveis diferentes de Hb Fetal e interações com talassemia alfa que atuam como modeladores genéticos da doença. Entretanto, outros defeitos genéticos dos eritrócitos, com destaques para a deficiência de G-6PD, a esferocitose e as deficiências de enzimas anti-oxidantes (SOD, GPx e catalase certamente interferem no curso clínico da doença. Os diferentes haplótipos da Hb S denominados por Banto, Benin, Senegal, Camarões e Asiático, tem sido apontados também como possíveis causas da heterogeneidade fenotípica da anemia falciforme. Toda essa diversidade que caracteriza a anemia falciforme está, em parte, relacionada à sua origem multicêntrica e que envolvem populações com diferentes anormalidades genéticas de proteínas e enzimas eritrocitárias. Por outro lado, além desses fatores caracterizados como interferentes eritrocitários, há os interferentes do meio ambiente em que está inserido o doente com anemia falciforme. Entre os interferentes ambientais destacam-se as situações sociais, econômicas e culturais do doente, e que tem influência no curso de sua doença. Diante desse quadro complexo e interativo, o presente artigo mostra a influência de certos interferentes eritrocitários e ambientais na anemia falciforme. Ao finalizar o artigo é proposto um protocolo de monitoramento laboratorial das síndromes falcêmicas, com destaque para a anemia falciforme.

    In this work are presented and discussed results of the formation and equilibrium of the plasma current in TBR, a small tokamak, designed and contructed at the Instituto de Fisica of Universidade de Sao Paulo. The measured breakdown curves for H 2 , A and He are compared with the predictions of a simple model with reasonable agreement. The influence of stray magnetic fields in the plasma formation is investigated and conditions are chosen to facilitate the breakdown. The time profile of loop voltage and plasma current for shots with plasma equilibrium are shown. A comparison is made between experimental results and analytical-numerical model for tokamaks discharges with ohmic heating. Reasonable agreement is obtained when Z, effective atomic number, is assumed as a parameter. (Author) [pt

  3. Formation of coronal cavities

    1986-01-01

    A theoretical study of the formation of a coronal cavity and its relation to a quiescent prominence is presented. It is argued that the formation of a cavity is initiated by the condensation of plasma which is trapped by the coronal magnetic field in a closed streamer and which then flows down to the chromosphere along the field lines due to lack of stable magnetic support against gravity. The existence of a coronal cavity depends on the coronal magnetic field strength; with low strength, the plasma density is not high enough for condensation to occur. Furthermore, we suggest that prominence and cavity material is supplied from the chromospheric level. Whether a coronal cavity and a prominence coexist depends on the magnetic field configuration; a prominence requires stable magnetic support

    We present a model for the formation of the recently-discovered TRAPPIST-1 planetary system. In our scenario planets form in the interior regions, by accretion of mm to cm-size particles (pebbles) that drifted from the outer disk. This scenario has several advantages: it connects to the observation that disks are made up of pebbles, it is efficient, it explains why the TRAPPIST-1 planets are ˜Earth mass, and it provides a rationale for the system's architecture.

    While interest in developing strategic alliances within the food system continues to increase, there remains considerable risk when firms adopt such a cooperative strategy. The risk is due in part to the lack of concrete guidelines that illustrate the steps or stages of alliance development and the important strategic and operational decisions required at each stage. The existence of such guidelines would facilitate alliance formation and enable managers and researchers to better understand a...

    The objective was to show the necessity and the importance of the training and formation of the dentist in radioprotection according to the recent proposal for technical regulations `Radiological protection directrixes in Medical and Dentistry radiodiagnostic` of the Secretaria do Vigilancia Sanitaria of Ministerio da Saude (SVSMS). This regulation establishes basic standards to radioprotection in the medical and dentistry areas, including principles, limits, obligations and basic controls for the man and environment protection, versus possible improper effects caused by the use of ionizing radiation sources. An analysis of the discipline programs of the Dentistry Schools of Rio de Janeiro state indicates that they show a little or none preoccupation by the radiological protection, which was confirmed through a survey applied toward responsible professors by department or radiology service to the dentistry Schools. This work suggests the creation or adaptation of the existing disciplines introducing radioprotection and images quality in radiodiagnostic, to improve, complement and to make uniform the formation of future dentists optimizing the solution of the identified problems.

    A joint sedimentation study is currently underway at the Netzahualcoyotl reservoir in Chiapas, Mexico, involving the Comision Nacional de Areas Naturales Protegidas (CONANP) of the Secretaria de Medio Ambiente y Recursos Naturales and the USDA Forest Service. The reservoir is adjacent to the Reserva de la Biosfera, Selva El Ocote, administered by CONANP. Ongoing research is intended to provide watershed and reservoir managers with strategies to protect the resources of Rio La Venta canyon. The Rio La Venta arm of the reservoir is incised into karst terrain, with near-vertical limestone walls up to 300 meters high. The canyon is fed by two rivers, Rio La Selva and Rio Negro, and is surrounded by pristine tropical forest. The majority of the clastic sediment (predominantly sand and fine gravel) entering the reservoir originates in the headwaters of the two rivers which are underlain by weathered and dissected granitic terrain. Rapid sedimentation of the partially inundated canyon poses a threat to the aquatic ecosystem, as well as to recreational resources. Longitudinal and transverse profiles were surveyed in the inundated canyon in March of 2002 and repeated in April of 2003 when the reservoir level was 15 meters lower. The 2002 longitudinal profile shows an inflection from a slope of 0.0017 to one of 0.0075 at 7.2 km downstream of the mouth of Rio Negro. In 2003, the two slopes remained the same, but the bed lowered about 5 meters and the inflection point moved downstream about 2.3 km. We calculated that reservoir lowering in 2003 allowed the transport of 2.5 million cubic meters of sand further out into the reservoir. This volume is more than the average annual rate of filling up to the 2002 level since 1984 when sedimentation was not as advanced (De la Fuente et al., 2002), which was calculated disregarding loss of sediment to the main reservoir. Field observations at late dry season low flows in 2003 revealed active transport of sand and pebbles and formation

    Full Text Available In order to evaluate environmental controls on the soiling formation and decay of building stones a set of mapping and physical and chemical analyses were carried out on granite from a historical church in the polluted centre of Rio de Janeiro. These techniques highlight the increasing of threatening damage on generally perceived as a durable building material, caused by granular disaggregation and contour scaling in areas close to ground level. Mapping also indicated the formation of black crusts over entire building façades, concentrated on areas sheltered from rain-wash. Analyses demonstrated the influence of marine aerosols, rock and mortar composition and mostly of the atmospheric pollutants on the decay and soiling of the granite. Much of the decay is associated specifically with the presence of halite (NaCl and gypsum (CaS04.2H2O. The fact that black, gypsum crusts are able to develop over entire façades in a humid subtropical environment is testimony to the high levels of local pollution, especially particulate deposition. Reduced rainwash, in sheltered micro-environments of narrow, canyon-like streets, overcomes the gypsum tendency to bewashed away from buildings façades. These observations further highlight that decay processes are primarily controlled by microclimatic conditions.Com o objetivo de se avaliar os controles ambientais na formação de crostas e deterioração de rochas ornamentais em fachadas de prédios históricos, uma série de mapeamentos e análises fisicas e químicas foram realizados em granitos da fachada de uma igreja histórica numa área poluída no centro da cidade do Rio de Janeiro. Estas técnicas destacam a ameaça crescente dos danos causados pela desagregação granular e esfoliação da rocha que é fortemente percebido por se tratar de um material de alta durabilidade usado na fachada do prédio em áreaslocalizadas ao nível do chão.

    Full Text Available The contemporaneity is characterized by instability and diversity calling into question certainties and truths proposed in modernity. We recognize that the reality of things and phenomena become effective as a set of events, interactions, retroactions and chances. This different frame extends the need for revision of the epistemological foundations that sustain educational practices and give them sense. The complex thinking is an alternative option for acting as a counterpoint to classical science and its reductionist logic and knowledge compartmentalization, as well as to answer to contemporary epistemological and educational challenges. It aims to associate different areas and forms of knowledge, without, however merge them, distinguishing without separating the several disciplines and instances of the realities. This study, in theoretical references, highlights the relevance of complex approaches to support formative experiences because also able to produce complexities in reflections about educational issues. We conclude that formative possibilities from complexity potentialize the resignification of human’s conception and the understanding of its singularity in interdependence; The understanding that pedagogical and educational activities is a constant interrogation about the possibilities of knowing the knowledge and reframe learning, far beyond knowing its functions and utilitarian purposes; and, as a formative possibility, places us on the trail of responsibility, not as something eventual, but present and indicative of freedom to choose to stay or go beyond.

  16. Terrestrial planet formation.

    Righter, K; O'Brien, D P

    2011-11-29

    Advances in our understanding of terrestrial planet formation have come from a multidisciplinary approach. Studies of the ages and compositions of primitive meteorites with compositions similar to the Sun have helped to constrain the nature of the building blocks of planets. This information helps to guide numerical models for the three stages of planet formation from dust to planetesimals (~10(6) y), followed by planetesimals to embryos (lunar to Mars-sized objects; few 10(6) y), and finally embryos to planets (10(7)-10(8) y). Defining the role of turbulence in the early nebula is a key to understanding the growth of solids larger than meter size. The initiation of runaway growth of embryos from planetesimals ultimately leads to the growth of large terrestrial planets via large impacts. Dynamical models can produce inner Solar System configurations that closely resemble our Solar System, especially when the orbital effects of large planets (Jupiter and Saturn) and damping mechanisms, such as gas drag, are included. Experimental studies of terrestrial planet interiors provide additional constraints on the conditions of differentiation and, therefore, origin. A more complete understanding of terrestrial planet formation might be possible via a combination of chemical and physical modeling, as well as obtaining samples and new geophysical data from other planets (Venus, Mars, or Mercury) and asteroids.

    The availability of gamma ray irradiators in Brazil increased the possibilities of treatments of gemstones for color enhancements. One of the minerals with a very high potential of these treatments is quartz, a very widespread mineral with many colored commercial varieties. A specific variety of quartz showing a green color in nature or induced artificially by radiation gamma ( 60 Co) is quite rare. In Brazil the widely scattered geode occurrences along a 600 km stretch from Quaraí at Brazil southernmost tip to Uberlandia in Minas Gerais is one of these. Quartz from these occurrences have been formed by strong hydrothermal activities. That way much quartz crystals showed a very fast growth history facilitating the formation of growth defects and the uptake of water in form of micro inclusions, molecular water, silanol (Si-OH) and OH. In the present work the material analyzed is from hydrothermal regimes located near the towns Entre Rios (SC) and Quaraí (RS). To characterize these materials analyses have been made by ICP, NAA, electron microscopy, water loss techniques and UV-VIS and NIR-FTIR spectroscopic measurements. Silanol complexes are found, which by radiation due to gamma rays form the color center NBOHC (Non-Bonding Oxygen Hole Center), showing absorption between 590 to 620 nm and leaving a transmission window at about 550nm, responsible for the green color. The spectroscopic water determination showed less molecular water (up to 2300 ppm by weight), probably due to remaining silanol complexes.The water content with up to 3200 ppm by weight exceeds the amount of charge balancing cations (Fe, Al, Li).

    Full Text Available On the occasion of the Fourth French-Brazilian itinerant seminar, “Cities and river in the history of Brazil: Rio São Francisco”, the text revisits articles published in 1978, 1980 and 1981, illustrated with 1977 photographs and new maps. Though often portrayed as one of the most promising regions in Brazil, and despite having been object, for the last seventy years, of various development projects, the São Francisco valley remains one of the most underdeveloped areas of the country. The history of its occupation partly accounts for this situation, as the São Francisco is the river of the sertão. The various attempts at reclaiming the region, since 1946, are due to various motives, some of them political, but they are also due to a mythical view of the São Francisco as being the “river of national unity”. From 1948 to 1967, the CVSF was rather unsuccessful, probably given too many tasks to carry out. Since 1967, the Suvale and then the Codevasf have focused their action on a few areas in which their main activity is irrigation, but the needs of hydroelectric-power threatens its development. The competition for water therefore makes it necessary to reappraise the future of the valley, gradually integrated into the economy of Brazil’s coastal regions.

    The Instituto de Radioprotecao e Dosimetria, IRD/CNEN, started in 1980 a program called 'PATIENT EXPOSURES IN ORAL RADIOLOGY'. The basic goal is the reduction of patient exposure during dental X-ray examinations. The program is being applied by mail to the pilot area of the city of Rio de Janeiro and covers the following topics: 1. Determination of skin doses and all physical parameters inherent to radiographic examinations wich are needed for effective dose equivalent calculations; 2. Guidance to dentists regarding proper techniques, basic procedures in Radiation Protection and aptimization of the radiographic image. According to the results obtained from 308 people studied the exposure ranged from 200mR to 4000mR at the patient skin during a molar X-ray. In regard to field diameter measurements in this group it was observed that 40% of the X-ray units used showed higher values than the acceptable limit of 7.5cm at skin. (Author) [pt

Sedimentation rate were obtained by CIC (Constant Initial Concentration) model assumes a constant sedimentation rate throughout the period over which unsupported {sup 210}Pb is measurable. Some sediment profiles were not dated since the percentage of sand was quite high in top layers or a high percentage of organic matter and water in excess were observed in the all sediment samples. {sup 210}Pb geochronology was successfully applied to age nine sediment profiles, in which higher sedimentation rates were observed in the middle portion of the estuarine probably related to shrimp farming impacts. By using geochronology, the detection of human impacts on chemical element distribution could be enhanced in the case of environmental monitoring studies in the Rio Formoso estuarine. (author)

Epidemiological data on salmonellosis, occurred in the period of 1997 to 1999 and supplied by the Division of Sanitary Surveillance (DVS/RS, were analysed according to the following factors: total number of confirmed outbreaks, number of people involved, outbreaks incidence according to the period of the year, age and sex of involved people, food vehicle, food storage conditions, local where the disease occurred, and possible causes of the outbreaks. The results indicated that 8217 people were involved, and 1557 had to be hospitalized. The highest number of outbreaks occurred during springtime and the principal age group affected was between 16 and 50 years. The most common food vehicle was salad prepared with homemade mayonnaise (42.45%. The principal causes of salmonellosis were raw-materials not submitted to regulatory inspection (22.92%, mainly eggs, and foods maintained at room temperature for more than 2 hours (20.55%. The majority of the outbreaks occurred in private homes (43.70% and commercial food establishments (25.21%.

    Full Text Available O imaginário da dor e da maternidade em Frida Kahlo suscita uma reflexão sobre uma harmonia entre as imagens presentes na consciência, em contraposição com o campo onírico. Neste sentido, como pensar o surrealismo com que muitos críticos insistem em rotular a arte de Frida? Nosso método se baseia na análise de algumas pinturas de Frida e de seu diálogo com o pensamento fenomenológico acerca das imagens, questionando o movimento surrealista como mera manifestação do inconsciente na arte. A noção de maternidade está em concordância com o pensamento dos agrupamentos sociais e de esferas, postulado pelo filósofo Peter Sloterdijk. Nosso objetivo é averiguar de que maneira os objetos artísticos de Frida Kahlo revelam uma existência da dor e do maternal enquanto dado imediato da consciência.

    Samples of muscovite and plagioclase were collected from the pegmatites located in the counties of Niteroi and Sao Goncalo, State of Rio de Janeiro. Geochronological Research Center of the University of Sao Paulo has selected some samples for pottasium-argon and rubidium-strontium analysis. Three samples of muscovite analysed by K-Ar dating method lave ages between 437+-13 and 447+-16 m.y and two others, by Rb-Sr dating method, gave 495+-15 and 500+-13 m.y.. One sample of plagioclase analysed by K-Ar method gave age of 337+-16 m.y.. In this paper, the locations of the analysed samples are described and the samples of vicinity are listed in the Appendix. Interpretation of the radiometrio ages and discussion of results are made. Taking into account the results of Table l and the geologic setting of the pegmatities sample in Niteroi and Sao Goncalo, we way conclude that all cooling ages (440-550 m.y.) are related to the Brasiliano Orogeny.

    The Rio Cristalino area where occurs uranium mineralization is located in the Western part of the Santana do Araguaia Town, Para State. This area comprises 1.350 Km 2 , and was selected from the evolution of the 'Projeto Geofisico Brasil - Canada - PGBC'. According to the results obtained from this Project, 15 airbone anomalies were selected for ground check. In the anomalies AN-03 and H-09 were found the best uranium occurence. The host rocks consist of arkose and sandstone of Pre-Cambriam ages, which show a very low-grade of metamorphism. The primary mineralization occurs in arkose along the cataclastic foliation (N70 0 W / 65 0 NE). The secundary mineralization involves clay galls and fills fracture zones in sandstone of the anomaly H-09. The highest grade detected in a rock sample of the anomaly AN-03 was 6,1% U 3 O 8 , whereas in the trenches there are intervals of 6 m thickness with a grade of 0,59% U 3 O 8 . Based on some mineralization aspects and field data, the genetic conceptual model to the uranium mineralization is proposed. (author) [pt

    Full Text Available O artigo tem como escopo repassar o contexto histórico-político no qual surge a chamada "geração de 37" e sua adaptação do romantismo no Rio da Prata. Para isso, analisam-se as diferentes abordagens críticas do Facundo. Civilização ou barbárie de Sarmiento, texto considerado fundador das letras argentinas, assim como as peripécias e publicações dos exilados do regime de Juan Manuel de Rosas, o caudillo a que estão dirigidas todas as críticas dos jovens românticos.The article aims to review the historical and political context in which the so-called "generation of '37" arose and their adaptation of the Romantic movement in the River Plate. To that effect, we analyze the different critical approaches to the Facundo. Civilization or Barbarism, by Sarmiento, considered the founding text of Argentinean literature, as well as the adventures and publications by those exiled by the regime of Juan Manuel de Rosas, the caudillo to whom the romantic youth directed all of their criticism.

    Full Text Available O relatório nacional brasileiro, elaborado como parte do processo de preparação da participação brasileira na Cúpula Mundial para o Desenvolvimento Social, busca traçar um quadro da situação do Brasil em relação aos três temas centrais do evento: alívio e redução da pobreza, expansão do emprego produtivo e integração social. Com o objetivo de qualificar a peculiaridade dos desafios sociais com os quais o Brasil se defronta, a primeira parte consiste de um quadro abrangente, onde estão expostos os dados gerais mais relevantes. A segunda parte, de caráter conceituai, explora a relação à dicotomia desenvolvimento econômico/desenvolvimento social, políticas econômicas/políticas sociais. Passa-se, então, à parte do relatório mais diretamente ligada aos temas centrais da Cúpula. O capítulo sobre pobreza busca sistematizar algumas das principais características desse fenômeno no Brasil; em "Emprego e mercado de trabalho" examinam-se questões como a baixa taxa de desemprego aberto do mercado brasileiro e sua relação com a má qualidade dos postos de trabalho existentes; finalmente, "Integração social e políticas sociais" salienta a necessidade de novas formas de solidariedade social, o que implicaria a reformulação da lógica de financiamento das políticas sociais e sua integração num conjunto coeso, ao lado de novas parcerias do Estado com a sociedade e do setor público com o setor privado. À guisa de conclusão, alinham-se as principais diretrizes do Governo Federal para o período 1995-1999. Depois de enfatizar a necessidade de que quatro condições prévias - fortalecimento da democracia, manutenção da estabilidade econômica, recuperação do crescimento sustentado e reforma do Estado - sejam alcançadas, identificam-se cinco metas prioritárias na área social: agricultura, educação, emprego, saúde e segurança. O relatório termina com breve esboço da estrutura do Programa Comunidade Solid

    This work presents the results of a dose survey performed for paediatric patients and carried out in two large paediatric public hospitals in Rio de Janeiro city. The entrance surface dose (ESD) and the effective dose (ED) were evaluated for chest, skull, abdomen, lumbar spine, cervical spine and pelvis in antero-posterior (AP), postero-anterior (PA) and lateral (LAT) projections. For each examination, four age groups 0-1, 1-5, 5-10 and 10-15 years were studied. The DoseCal software was used to calculate these doses. Wide variations for the same type of examination and projection have been detected. These variations were evident, in Brazil, from previous work. In spite of the present results being still preliminary, they can give an idea of what paediatric ESDs are like in Brazil. Also, with respect to the entrance surface dose, some of the results are above the reference levels, which cause high ED, as well. On the other hand, the wide range of ESD reflects the disparity of radiographic techniques and demonstrates that the ALARA principle is not being applied in Brazilian hospitals and becomes a concern in terms of public health

    Samples of muscovite and plagioclase were collected from the pegmatites located in the counties of Niteroi and Sao Goncalo, State of Rio de Janeiro. Geochronological Research Center of the University of Sao Paulo has selected some samples for potassium-argon and rubidium-strontion analysis. Three samples of muscovite analysed by K-Ar dating method gave ages between 437±13 and 447±16 m.y and two others, by Rb-Sr dating method, gave 495±15 and 500±13 m.y.. One sample of plagioclase analysed by K-Ar method gave age of 337±16 m.y.. In this paper, the locations of the analysed samples are described and the samples of vicinity are listed in the Appendix. interpretation of the radiometric ages and discussion of results are made. Taking into account the results of Table 1 and the geologic setting of the pegmatites sampled in Niteroi and Sao Goncalo, we way conclude that all cooling ages (440-550 m.y.) are related to the Brasiliano Orogeny. These pegmatites are regard as having same geological history and their ages are supposed 500 m.y [pt

    Full Text Available Partindo do texto do escritor português José Cardoso Pires, "De Profundis: Valsa Lenta", em que o autor descreve a afasia pela qual passou em conseqüência de acidente vascular cerebral, são feitas considerações sobre o enfoque da doença por escritores e por médicos. As diferenças apontadas, em termos da forma e do conteúdo dos textos que, na literatura e na medicina, descrevem a doença, enquadram-se no conflito entre as duas culturas, tal como descrito por C. P. Snow, sendo característico da crescente especialização. A inclusão de textos literários no treinamento de médicos e de profissionais da saúde pode ajudar a superar esse hiato, facilitando o entendimento da doença em sua dimensão mais ampla e contribuindo para um melhor relacionamento profissional-paciente.

    The extractive exploitation of the tree fern Alsophila setosa Kaulf. alters forest formations and diminishes the availability of micro-habitat for epiphytes. A survey of epiphytic fern communities on A. setosa at 16 study sites in different forest formations in the State of Rio Grande do Sul, Brazil, documented the occurrence of 31 species representing 16 genera and six families. The greatest richness of species occurred in Polypodiaceae (39%) and in the genus Asplenium L. (22%). Habitual holoepiphyte was the predominant ecological category, representing 61% of the species. Similarity analysis demonstrated heterogeneity in the composition of the epiphytic ferns at the study sites and indicated that the vegetation type is not the main factor for floristic difference. The lowest total specific richness (5) was recorded for the seasonal deciduous forest site. The majority of the sites presented similar averages of phorophyte height and epiphyte richness per caudex. In 25% of the sites the height of the host plants presented significant correlation with specific richness. Considering that the majority of the epiphytes are habitual and that some of them occur exclusively or preferentially on tree ferns, the maintenance of these host plants in the vegetation is essential for the conservation of epiphytic species.

    The Rio Cajarí Extractive Reserve (RCER) is a sustainable use protected area located in Southern Amapá state, Brazil. This protected area is home to traditional agro-extractive families, but has been increasingly invaded by commercial agriculture producers. In this work, we test the hypothesis that the RCER implementation has distinctly affected spatial patterns of deforestation and rates of bare soil and secondary forest formation by the social groups occupying the protected area and its surrounding area. Detailed maps of vegetation cover and deforestation were elaborated, based on Landsat TM images from 1991, 1998, 2007 and 2008 and Linear Spectral Mixture Models. Based on an extensive fieldwork, patches were classified according to the agents causing deforestation and characterized with ten explanatory variables. A discriminant function analysis was used to identify homogeneous groups based on the data. Results show increased rates and distinct spatial patterns of deforestation by three groups: extractivists, non traditional commercial agriculture producers, and a less representative group constituted of miners, cattle and timber producers. In all analyzed dates, clearings by the extrativist community presented the highest total area and smaller average sizes and were located in close proximity to villages. Deforestation patches by the non-traditional group were exclusively associated with ombrophilous forests; these presented higher average sizes and proximity indexes, and showed increased aggregation and large cluster formation. No significant differences were observed in deforestation patterns by the three groups inside or outside the reserve.

    The objective was to show the necessity and the importance of the training and formation of the dentist in radioprotection according to the recent proposal for technical regulations 'Radiological protection directrixes in Medical and Dentistry radiodiagnostic' of the Secretaria do Vigilancia Sanitaria of Ministerio da Saude (SVSMS). This regulation establishes basic standards to radioprotection in the medical and dentistry areas, including principles, limits, obligations and basic controls for the man and environment protection, versus possible improper effects caused by the use of ionizing radiation sources. An analysis of the discipline programs of the Dentistry Schools of Rio de Janeiro state indicates that they show a little or none preoccupation by the radiological protection, which was confirmed through a survey applied toward responsible professors by department or radiology service to the dentistry Schools. This work suggests the creation or adaptation of the existing disciplines introducing radioprotection and images quality in radiodiagnostic, to improve, complement and to make uniform the formation of future dentists optimizing the solution of the identified problems.
