Produção, qualidade dos frutos e estado nutricional da laranja valência sob fertirrigação e adubação convencional

O objetivo deste trabalho foi comparar os efeitos de doses de nitrogênio, fósforo e potássio aplicadas via água de irrigação em comparação à aplicação convencional de fertilizantes, com irrigação e sem irrigação. O experimento foi conduzido em um pomar de laranja 'Valência' (Citrus sinensis Osbeck) localizado em Pratânia - SP, durante três anos consecutivos, e analisados os dados do último ano de observação. As diferentes formas de aplicação dos fertilizantes e a redução das doses fornecidas via água de irrigação não resultaram em diferenças significativas sobre o número médio de frutos e produtividade. Também não foram constatadas diferenças estatísticas dos tratamentos sobre a qualidade do suco e o estado nutricional das plantas, com exceção do teor de fósforo.

Valência do nome deverbal e nominalidade prototípica

O objetivo deste trabalho é mostrar que os nomes deverbais preservam a estrutura argumental do verbo input correspondente e que a especificação ou não dos argumentos no interior do termo nominal depende de um conjunto de fatores pragmáticos, especialmente relacionados a informação de curto termo compartilhada pelos participantes da interação. Como implicação teórica, a análise preserva a idéia de que há um processo gradual de descategorização verbal, que se reflete nos diferentes tipos de marcação gramatical. Conforme o predicado verbal ganha estatuto nominal, as marcações tipicamente oracionais dão lugar a outros mecanismos, como marcação argumental por preposição, modificação por adjetivo, uso de pronomes possessivos, que acompanham apropriadamente um núcleo nominal.

Evaluation of the in vitro activity of cefepime compared to other broad-spectrum cephalosporins against clinical isolates from eighteen Brazilian hospitals by using the Etest

The in vitro activity of cefepime was compared to that of ceftazidime, ceftriaxone, and cefotaxime in a multicenter study involving 10 clinical microbiology laboratories and clinical isolates from 18 Brazilian hospitals from 7 cities (4 states). A total of 982 isolates consecutively collected between December 1995 and March 1996 were susceptibility tested by using Etest and following the NCCLS procedures for agar diffusion tests. The cefepime spectrum was broader than that of the other broad-spectrum cephalosporins against both Gram-negative rods and Gram-positive cocci. Cefepime tons particularly move active against Enterobacter sp. (MIC90, 2 mu g/ml), Serratia sp. (MIC90, 2 mu g/ml) and oxacillin-susceptible Staphylococcus aureus (MIC90, 3 mu g/ml). Against Pseudomonas aeruginosa, cefepime (MIC90 16 mu g/ml) was slightly more active than ceftazidime (MIC90 32 mu g/ml) and 8- to 16-fold more active than ceftriaxone or cefotaxime (MIC90 >256 mu g/ml). Our results show that nosocomial bacteria, especially Gram-negative rods, have a high rate of cephalosporin resistance in Brazil. However, part of these resistant bacteria remains susceptible to cefepime. The Etest was shown to be an excellent method for multicenter studies of the in vitro evaluation of new antimicrobial agents. (C) 1997 Elsevier B.V.

ANTS AS POTENTIAL VECTORS OF PATHOGENS IN HOSPITALS IN THE STATE OF SAO-PAULO, BRAZIL

Baiting studies performed in large, medium and small hospitals in Brazil revealed the presence of 14 ant species, with up to nine recorded in one hospital. Dominant species were exotic ants, and in the large hospital, Tapinoma melanocephalum was the most prevalent. Ants were not uniformly spread through the hospitals, but tended to be found in the more critical areas, particularly in nursery, intensive care, obstetrics, neurology and dermatology units. Bacteriological studies using specific media for bacteria associated with intra-hospital infections indicated the potential for the mechanical vectoring of species of Staphylococcus, Serratia, Klebsiella, Acinetobacter, Enterobacter, Candida and Enterococcus by ants. Although T. melanocephalum did not have the highest rate of association with these bacteria, its ubiquitous occurrences resulted in the highest overall potential as a vector of these bacteria. Because of a large number of ant species occurring in Brazilian hospitals, ants pose a potential problem to the spread of diseases in hospitals. Because of the number of associated ant species in hospitals, the control of this potential problem is much more difficult than in registered temperate areas.

A justiça e a produção do Direito em Castela no século XV

The Catholic kings government - Fernando of Aragon and Isabel of Castille - (1474-1504) is set in Middle to Modern Age transition period and was considered a period of justice and peace in Castille. It makes us possible to question about implications, to law, of a kingdom organization in a transition era. We propose to verify what characterize the passage from a medieval law to a modern law, and which elements indicate this transition in catholic kings government. We emphasize two main prerrogatives, a medieval tradition, a judge one, and another of modern character, the legislative, that close on Fernando and label tradition.

Avaliação dos teores nutricionais em laranjeira 'Valência', sob fertirrigação

This work aimed to compare fertigation to conventional fertilization in a five-year-old 'Valência' orange orchard, irrigated by microsprinklers. The conventional fertilization, using the recommended dosage for the crop, was parceled out in three during the year. In the fertigation treatments a complete dose, 1/2 and 1/3 of the conventional fertilization dose, parceled out in ten in a year, were used. Trunk circumference and leaf volume, leaf chlorophyll content and fruit yield and quality were measured. For the first year, significant differences among the treatments for the evaluated parameters were not observed; however, it was noticed that fertigation treatments caused less nutritional unbalance, obtained by DRIS. The fertigation treatment using half dosage showed the best result regarding to fruit yield and quality.
