Fixa??o biológica e transferência de nitrogênio por leguminosas em pomar organico de mangueira e gravioleira
Paulino, Gleicia Miranda;Alves, Bruno José Rodrigues;Barroso, Deborah Guerra;Urquiaga, Segundo;Espindola, José Antonio Azevedo;
Pesquisa Agropecuária Brasileira , 2009, DOI: 10.1590/S0100-204X2009001200006
Abstract: the objective of this work was to evaluate the biological nitrogen fixation (bnf) and the n transfer derived from bnf of the legume species - gliricidia sepium (gliricidia), crotalaria juncea (sunnhemp) and cajanus cajan (pigeon pea) - for an intercropped organic orchard with mango and soursop, through the 15n natural abundance method. the following intercropping systems were evaluated: mango and soursop with gliricidia; mango and soursop with sunnhemp; mango and soursop with pigeon pea; and mango and soursop as control. gliricidia showed the highest bnf potential (80%) , followed by sunnhemp (64.5%) and pigeon pea (45%). after two sunnhemp prunes, 149.5 kg ha-1 of n per year were supplied, with 96.5 kg derived from bnf. after three annual prunes, gliricidia supplied 56.4 and 80.3 kg ha-1 of n per year, with 45 and 64 kg derived from bnf, in two consecutive years. the quantity of n supplied to the system was higher than the mango and soursop requirements. variations in the natural abundance of 15n were found only in soursop leaves. gliricidia and sunnhemp were prominent in n transfer, with approximately 22.5 and 40% respectively. green manuring using gliricidia permits fractioning of the n supply, which is an advantage in n obtention by the fruit trees.

Revista Brasileira de Ciência do Solo , 2008, DOI: 10.1590/S0100-06832008000400016
Abstract: the objectives of this study were to evaluate the influence of three soil cover species acacia auriculiformis, mimosa caesalpiniifolia and corymbia citriodora compared to pasture and natural secondary forest on soil chemical and microbial attributes. the field survival rate of the species reached over 70% and the development in height and diameter (dap) was adequate. the survival rate of mimosa caesalpiniifolia was the highest among the legume species, while the development of acacia auriculiformis was the best, mainly between 27 and 44 months. the forest species improved soil fertility adequately in the initial development stages, in spite of the reduction in the levels of organic matter. the potential of pasture to maintain the level of organic matter and improve soil fertility was shown. microbial c and n were more discriminating, regarding changes in land cover than soil c content. the microbial quotients (qco2, cbm/c, nbm/n and microbial c/n) detected differences among land covers more clearly than the chemical (c and n content) and microbial (cbm, nbm and ra) attributes.

Abstract: the objective of this study was to determine mixtures of regional organic residues that present aggregation to the root system and make a good development possible for eucalyptus seedlings in block systems. residues of coconut fiber (fine fibers - fcf, long fibers - fcl and mixed fibers - fcm), eucalyptus bark (ce) and sugarcane filter cake (t) were used, with ten mixtures obtained. the blocks for the expansion tests were made in a steel form (11.5 x 2.3 cm), and afterwards moistening and evaluating for the volume and height increment. there was not a difference in the volume increment among the mixtures, and mixture 3 presented a larger increment in height than in mixture 8, however, they didn't differ from those remaining, with those chosen for use in the production of eucalyptus seedlings: fcm (40%) + t (60%); ce (60%)+ fcm (40%); ce (40%) + t (60%) and ce (40%) + t (30%) + fcm (30%). the choice was made in consideration of the component's readiness, because it did not differ in the tests. the eucalyptus urophylla seedlings were produced in 40x60x7cm trays, with 96 seedlings, sown directly in the blocks made with the selected mixtures pressed or not pressed. at 90 days the seedlings were evaluated for the diameter, height, shoot and root dry matter. in the expedition time, the substrata were evaluated as for the stability of the turf and the aggregation degree of the substrata to the seedlings roots. the nutritional analysis of the shoot seedlings was accomplished (n, p, k, ca, mg, mn, zn, fe). all the substrata presented aggregation and good stability. nutritional problems were not observed in the seedlings. for the production of eucalyptus urophylla seedlings in blocks with pressed substrata the substratum ce (60%) + fcm (40%) is recommended, and without being pressed the mixtures: ce (60%) + fcm (40%); ce (40%) + t (60%) and ce (40%) + t (30%) + fcm (30%) were recommended.

Abstract: an alley cropping system with gliricidia was established in an organic orchard of mango and soursop trees at one year after the planting of the fruit trees, in campos dos goytacazes-rj-brazil. the objective of this work was to evaluate the survival and performance of the gliricidia in the alley cropping in relation to the production of dry fitomass and the nutrient supply to the system. gliricidia showed high survival rates (93%). the annual average of dry fitomass yield and the addition of nutrients to the system were greater in the second year of evaluation (2007) than in the first year (2006), both with three annual prunings that adjusted with the recommended periods of fruit trees fertilization, in special the soursop tree. the quantity of n added to the orchard with gliricidia prunes was higher than the recommended fertilization for mango and soursop tree plots. on the other hand, quantities of p and k added to the orchard were not enough to supply the fertilization demanded for both cultures. gliricidia presented good performance under the experiment conditions, with potential for continuous use in the system and possibility of using nutrients supplied by the fruit trees into the system. however, further long term evaluations are necessary to verify the sustainability of the intercropping.

Abstract: Actinic cheilitis can progress to squamous cell carcinoma in 20% of cases. The purpose of this study was to identify the clinical characteristics of 75 patients with actinic cheilitis and to summarise the current literature concerning actinic cheilitis. A total of 75 patients were evaluated over a 3-year period. The medical history, physical examination results and images were collected from each patient. Demographic data were collected and analysed. To review the literature, the relevant data were collected from scientific journals in the last 30 years. The mean age of the patients was 56 years old; 42 patients (56%) were female, and 66 patients (88%) were white. Nineteen (25.3%) patients reported at least one symptom, including pain, burning and itching. Sixty-five (86.7%) patients presented actinic cheilitis only in the lower lip. All of the patients reported sun exposure, and 44 (58.6%) patients were exposed for more than 10 years. The main clinical aspects investigated and analysed included dryness (100%), flaking (72%) and white lesions (57.3%). Lip assessment is extremely important in medical and dental care. From the 15 lesions assessed in the presence of actinic cheilitis, the most common clinical characteristics observed were dryness, flaking and white lesions. It is imperative to know the clinical aspects that may be encountered in actinic cheilitis in order to achieve early diagnosis, thus avoiding lip squamous cell carcinoma transformation.

Abstract: introduction: leishmaniasis is an extremely important parasitic disease as regards epidemiology, and, in such a disease, man is an occasional host to the leishmania protozoon. some of the major clinical, visceral and integumentary features are the mucocutaneous ways that can harm face and upper airways and even cause deforming lesions, leading to a functional impairment. objective: review the main dermatologic and otorhinolaryngologic manifestations in leishmaniasis. methods: it was based on the virtual health library (bvs), by entering the following keywords: leishmaniasis, mucocutaneous leishmaniasis, nasal mucosa, and nose. references dated from 1999 to 2008 have been regarded. final comments: it is about a zoonosis, in which the human being is an occasional host attacked by lutzomya or phlebotomus insects that are, in turn, infected by the leishmania parasite, and the early diagnosis of a leishmania-related lesion is essential, especially when a nasopharyngeal impairment is evident, with a view to preventing deformities or functional harms. the evaluation of cutaneous and/or mucosa lesions and the accurate definition of leishmaniasis diagnosis given by either dermatologists or otorhinolaryngologists enables the proper treatment to be implemented and the subsequent reduction in the disease dissemination.
Introdu??o à Teoria Quantica de Campos: do Oscilador Harm?nico ao Campo Escalar Livre

Revista Brasileira de Ensino de Física , 2002, DOI: 10.1590/S1806-11172002000200021
Abstract: quantum field theories are central to both condensed matter and high-energy physics. in this article, we show how a typical field theoretical formalism can be pedagogically constructed by generalizing the solution of a harmonic oscillator to a large number of degrees of freedom. in the continuum limit, this method leads to the quantization of the field of a vibrating stretched string as well as to the existence of phonons as elementary excitations ("particles") of this field. the procedure can be used as an elementary introduction to quantum field theory by means of tools taught at an undergraduate course in quantum mechanics.

Revista Brasileira de Ensino de Física , 2002,
Abstract: As teorias quanticas de campo s o fundamentais em teoria de Matéria Condensada e Física de Altas Energias. Nesse artigo mostramos como um formalismo típico de teorias de campos pode ser introduzido didaticamente, generalizando a solu o do oscilador harm nico para um grande número de graus de liberdade. No limite contínuo, esse método nos leva à quantiza o do campo de uma corda esticada vibrante e à existência dos f nons como excita es elementares ("partículas") desse campo. O procedimento pode ser usado como introdu o elementar às teorias quanticas de campo através de ferramentas ensinadas em um curso de gradua o de Mecanica Quantica.
