Abstract: the objectives of the present study were to investigate the influence of liming and mineral and organic fertilization on yields of cv. 'montenegrina' tangerines (citrus deliciosa tenore) grafted onto poncirus trifoliata raf. the grove was planted in july of 1988 on a dark-red podzolic (rhodic paleudult) soil. the experiment was set up in randomized blocks design composed of nine treatments and four replicates, with three plants per plot. the treatments were: control (without liming and fertilizers); soil acidity neutralization to ph 6,5 before planting; annually poultry manure and liming; annually cattle manure and liming; annually n and k fertilizers and liming; annually n and k fertilizers, liming and p fertilizer before planting; annually n, p and k fertilizers and liming; annually n, k and double the rate of p, and liming; annually n, p and k fertilizers without liming. the results showed that p application before planting were sufficient to maintain adequate fruit yield up to eight years after planting. the increases of leaf n contents was positively related to increases in production and to decreases of the average fruit weight. the ammonium sulphate application acidifies the soil, and requires a greater quantity of liming support.

Abstract: the mandarin 'montenegrina' (citrus deliciosa ten.) yield from plants propagated either by grafting or cutting was evaluated at the 'universidade federal do rio grande do sul' experimental agronomic station, southern brazil, from 1993 to 1998. three rootstocks were used in the grafted plants. the rootstocks studied were: 'swingle' citrumelo [citrus paradisi macf. x poncirus trifoliata (l.) raf.] 'troyer' citrange (citrus sinensis x p. trifoliata) and trifoliate orange (p. trifoliata). the work was done using a randomized blocks design, with four replicates and five useful plants per plot. the yield and fruits number per plant were evaluated from 1993 to 1998. the 1995 yield was not significative due to alternation. 'swingle' citrumelo rootstock promoted higher productive efficiency in 'montenegrina' mandarins. trifoliate orange decreased the vegetative development but induce low productive efficiency in 'montenegrina' mandarins. cutting was a worse plant propagation strategy than grafting when 'swingle' citrumelo and 'troyer' citrange were used as rootstocks.

Abstract: A tangerineira-'Montenegrina' (Citrus deliciosa Ten.), devido às boas características de sabor, conserva o e colheita tardia dos frutos, é muito apreciada e cultivada no Rio Grande do Sul. Os pomares comerciais s o praticamente formados por mudas enxertadas sobre Poncirus trifoliata (L.) Raf. Devido à escassez de informa es relativas à combina o desta cultivar com outros porta-enxertos, bem como sua propaga o por estaquia, esta pesquisa objetivou estudar o comportamento inicial de plantas enxertadas sobre citrange 'Troyer' (Citrus sinensis (L.) Osb. x P. trifoliata), citrumelo 'Swingle' (C. paradisi Macf. x P. trifoliata) e P. trifoliata e de plantas propagadas por estaquia. O experimento foi instalado na Esta o Experimental Agron mica da Universidade Federal do Rio Grande do Sul - UFRGS, em junho de 1989, delineado em blocos casualisados, com cinco plantas úteis por parcela e quatro repeti es. Os resultados compreenderam as primeiras safras ocorridas de 1993 a 1998. O citrumeleiro 'Swingle' foi o porta-enxerto que melhores resultados apresentou, aumentando a eficiência produtiva da tangerineira-'Montenegrina', cultivada na Depress o Central do Rio Grande do Sul, sendo que o Poncirus trifoliata diminuiu o desenvolvimento vegetativo das copas e induziu baixa eficiência produtiva. A propaga o por estaquia n o ofereceu vantagens em rela o à enxertia sobre citrumeleiro 'Swingle' e citrangeiro 'Troyer'.

Abstract: the objective of the present work was to evaluate the development of the citrus rootstock poncirus trifoliata, severity of citrus canker, caused by xanthomonas citri pv. citri and the control of this disease with copper sprays, in conventional and organic management systems, at the centro de forma??o da emater, located in montenegro, rio grande do sul. plants were artificially inoculated with the bacteria. to control citrus canker, different sources of copper as well as concentrations and number of sprays were tested. in the organic system the bordeaux mixture was applied while in the conventional system copper oxichloride was sprayed. plants trunk diameter, dry matter of the rootstocks and number of canker lesions on leaves and branches were evaluated in both systems. citrus canker incidence on the rootstocks was equally intense, and the seedlings development was similar in both systems, but the budded plants grew better at the conventional system. copper treatments were not effective in controlling citrus canker at the rootstocks due the high inoculum concentration. on the budded plants, with low inoculum concentration, both the bordeaux mixture and the copper oxichloride controlled the disease, and the better treatments were when 0.3% metallic copper was applied with interval of 14 days. to improve citrus canker control by bordeaux mixture on organic systems, there is a need of efficient control strategies of the citrus leaf miner.

Revista Brasileira de Cirurgia Cardiovascular , 2000,
Abstract: Na revasculariza o do miocárdio com o cora o batendo, a exposi o das artérias posteriores durante a esternotomia pode levar à deteriora o hemodinamica necessitando um suporte inotrópico. Estudos experimentais recentes demonstraram o benefício hemodinamico da assistência ventricular direita (AVD). OBJETIVO: Avaliar os efeitos hemodinamicos da AVD durante a manipula o cardíaca para expor as artérias coronárias posteriores, determinando seu efeito em: restaurar a hemodinamica, aumentando a exposi o anastomótica e diminuindo o uso de inotrópicos. CASUíSTICA E MéTODOS: Onze pacientes (6 homens / 5 mulheres), com idade média de 63,3 anos (49-74) foram revascularizados utilizando AVD. Todos tiveram pelo menos 1 ramo da artéria circunflexa (CX) revascularizado. A parede anterior foi revascularizada sistematicamente sem circula o extracorpórea (CEC) ou AVD. A artéria coronária direita (CD) e o ramo da CX foram completados em AVD. A press o arterial média (PAM), a press o média da artéria pulmonar (PAP) e o débito cardíaco (DC) foram registrados durante as anastomoses CD e CX. RESULTADOS: Os dados foram registrados da seguinte maneira: 1) base em normoposi o; 2) CX em posi o AVD Off; 3) CX em posi o AVD On; 4) CD em posi o AVD Off; 5) CD em posi o AVD On. CONCLUS ES: A AVD suporta e facilita a revasculariza o sem CEC para as artérias coronárias posteriores, restaurando a hemodinamica, possibilitando melhor exposi o para as anastomoses e, aparentemente, reduzindo a necessidade de uso de inotrópicos. Estudos prospectivos randomizados s o necessários para confirmar esta experiência inicial.

Scientia Iuris , 2012,
Abstract: Este trabalho busca analisar o tratamento constitucional da extin o da punibilidade nos crimes tributário sem face do pagamento integral dos tributos sonegados ou da suspens o da pretens o punitiva pela sua inclus o em programas de parcelamento. Adotou-se a pesquisa bibliográfica e documental. Constatou-se que a política tributária nacional,concretizada pela regularidade de privilégios explícitos, estimula a inadimplência e o autofinanciamento de criminosos com recursos públicos, e que o tratamento privilegiado dispensado à criminalidade tributária agride a ordem constitucional brasileira,impedindo a distribui o de riqueza e violando o princípio da capacidade contributiva.
