Ocorrência de Commelina villosa como planta daninha em áreas agrícolas no estado do Paraná-PR, Brasil

As trapoerabas pertencem à família Commelinaceae e são plantas daninhas de difícil controle em diferentes regiões do país. No Brasil, a espécie Commelina benghalensis destaca-se como a principal trapoeraba infestante nas culturas de soja, milho, café e citros. Outras duas espécies desse gênero, Commelina diffusa e Commelina erecta, também são conhecidas como infestantes de ocorrência freqüente no território nacional. Commelina villosa está registrada, até o momento, apenas para os Estados da Bahia e Goiás além do Distrito Federal. O presente trabalho teve como objetivos caracterizar e registrar a ocorrência de C. villosa no Estado do Paraná, onde pode estar sendo confundida com outras trapoerabas, principalmente C. benghalensis. Exemplares de C. villosa e C. benghalensis foram coletados, de forma aleatória, em lavouras de soja, feijão e milho, nos municípios de Ponta Grossa, Tibagi, Piraí do Sul, Guarapuava, Pato Branco, Francisco Beltrão, Cascavel, Campo Mourão e Londrina. Parte desse material foi herborizado para a confecção de exsicatas e outra parte foi mantida in vivo, cultivada no Departamento de Botânica, do Instituto de Biociências de Botucatu-UNESP. Caracteres morfológicos descritivos e quantitativos foram avaliados e as espécies comparadas entre si. C. villosa distinguiu-se de C. benghalensis por apresentar folhas maiores (9,76 x 3,26 cm), elíptica a elípticaestreita, sésseis, de coloração verde escura com manchas violáceas na face inferior, filetes translúcidos, entre outras características. A ocorrência de C. villosa no Paraná foi constatada em todos os municípios amostrados, com exceção de Campo Mourão e Londrina.

Atividade reprodutiva de Scinax rizibilis (Bokermann) (Anura, Hylidae) na Floresta Atlântica, sudeste do Brasil

The breeding activity of Scinax rizibilis (Bokermann, 1964) was observed in a temporary pond, in the municipality of Ribeirão Branco, in the Southern São Paulo State from February 1993 to January 1994 and November 1994 to February 1995. The reproductive season extended from September to February. Females were larger and heavier (after oviposition) than males. In the choras, the spatial distribution tended towards uniformity. The number of males and females in the chorus was positively correlated. However there was no correlation between the number of males and the estimation of the operational sex ratios. on average there were seven males for each female present in the chorus. The males were apparently selected by females.

A HbAS têm as seguintes freqüências, quanto ao grupo racial: branco - 1,84%; mulato claro 2,55%; mulato médio-3,68%; mulato escuro - 6,80%; negro -10,43% e mestiço de índio -3,85%.

Geologic e geoquímica do batólito Rapakivi Rio Branco, SW do Craton Amazônico - MT

The Rio Branco Rapakivi Batholith belongs to the Cachoeirinha Tectonic Domain, part of the Rio Negro-Juruena Geochronological Province located on the southwestern portion of the Amazonian Craton in Mato Grosso, Central Brasil. A systematic geological mapping on a 1:100.000 scale, coupled with petrographic and geochemical studies allowed to redefine this batholithic unit, to recognize faciological variations and to characterize the geochemical features of this rapakivi magmatism. The batholith is constituted by two major plutonic suites, the first forming a basic suite of fine-grained, equigranular, mesoto melanocratic gray to black lithotypes, with usually discontinuous porphyritic varieties located near the margins of the intrusion. The second one is characterized by acid to intermediate rocks constituted by porphyritic granites, in part granophyric, with rapakivi textures. They have K-feldspar phenocrysts of up to 4cm. Three distinct petrographic facies are recognized in this suite: 1. equigranular to pegmatitic monzogranites; 2. red rapakivi leuco-monzogranites; 3. dark red rapakivi monzogranites to quartz-monzonites. Rocks present SiO2 contents from 67% to 73%, show peraluminous to metaluminous compositions and define a high-K calc-alkaline to shoshonitic magmatism in an I- and A-type, post-orogenic to anorogenic intraplate environment. The magmatic processes are associated with the end of the collisional event that consolidated and stabilized the SW part of the Amazonian Craton.

Avaliação dos resultados neonatais do método canguru no Brasil

Objective: To evaluate the results of the kangaroo mother method in Brazil. Methods: A prospective cohort study comparing 16 units that have or do not have the second phase of the kangaroo mother method: eight were national centers of excellence for the kangaroo mother method (study group) and eight were part of the Brazilian Neonatal Research Network (control group). A total of 985 newborn infants with birth weights of 500 to 1,749 g were enrolled. Multivariate analyses employedmultiple linear regression and Poisson regression with robust adjustment. Results: The adjusted analysis (controlled for birth weight, gestational age, Score for Neonatal Acute Physiology Perinatal Extension II, Neonatal Therapeutic Intervention Scoring System, and maternal age and educational level) demonstrated that mean length of hospital stay (p = 0.14) and intercurrent clinical conditions in the intermediate or kangaroo unit were equal for both groups. Weight (p = 0.012), length (p = 0.039) and head circumference (p = 0.006) at 36 weeks' corrected gestational age were all lower at the kangaroo units. The kangaroo units exhibited superior performance in relation to exclusive breastfeeding at discharge (69.2 vs. 23.8%, p=0.022). Conclusions: The evidence suggests that the humanization strategy adopted by the Brazilian Ministry of Health is a safe alternative to conventional treatment and a good strategy for promoting breastfeeding.

Variação sazonal de alguns parâmetros físicos e químicos em três rios pertencentes a uma bacia de drenagem na região centro-sul do Estado do Paraná, Sul do Brasil

Three small rivers belonging to the Rio das Pedras basin, located in the mid-southern region of Paraná state, were studied in order to evaluate the seasonal variation pattern of some physical and chemical parameters. Monthly samplings were carried out from April 2004 to March 2005. The following limnological parameters were measured: water temperature, specific conductance, oxygen saturation, pH, turbidity, current velocity and depth. The waters of the Rio das Pedras basin presented very peculiar characteristics, showing typical seasonal patterns for some of the studied limnological variables. An Analysis of Variance (Anova) showed significant differences only for pH and depth among streams. A Principal Component Analysis (PCA) showed a weak tendency to form groups based on seasons instead of sampling sites. The results, in general, indicate that temporal variations of the environmental parameters analyzed were not sufficient to draw a clear seasonal pattern in the Rio das Pedras basin. Most likely, the lack of an obvious seasonal pattern has been provoked by a particular regional precipitation regime, where rains are frequent and well-distributed throughout the year.

Magmatismo do batólito rapakivi Rio Branco, sw do Cráton Amazônico (MT)

Rio Branco Rapakivi Batholith is located on the southwestern portion of the Amazonian Craton in Mato Grosso and belongs to the Cachoeirinha Tectonic Domain, part of the Rio Negro-Juruena Geochronological Province, Central Brasil. The batholith is constituted by microgabbros to quartz microgabbros and microdiorites to quartz microdiorites, middle to fine-grained equigranular to porphyritic varieties form the Rio Branco Intrusive Basic Suite, showing a discontinuous distribution and located near the margins of the intrusion.Majorly constituted by porphyritic, granophyric and isotropic facies of Rio Branco Intrusive Acid Suit which is composed by older dark red rapakivi monzogranites to quartz monzonites and quartz sienites (1403±0.6 Ma) and the younger red rapakivi leuco-monzogranites (1382±49 Ma) and late equigranular to pegmatitic monzogranites. The magmatism is constituted by two distinct magmas related to the end of the collisional event of Cachoeirinha Orogeny, one with alkaline basalts generated in an intraplate environment and the other postorogenic to anorogenic with peraluminous to metaluminous compositions and define a high-K calc-alkaline to shoshonitic magmatism in transition among the I- and A-types. The contacts are marked by extensive mafic sills and dikes of alkaline basalts derived from intraplate environment of the Salto do Céu Intrusive Basic Suite (±808 Ma) associate to the Sunsás-Aguapei Orogenic Belt and metasedimentary rocks of the Aguapeí Grup.
