Abstract: a case of one month of evolution, of an 8-year-old equine of undefined breed, presenting alopecic areas, crusts on the upper eyelid, forelimbs, hindlimbs, preputial region and mainly, on the neck and scapula is reported. pruritus was discrete. the histological analysis revealed pyogranulomatous dermatitis round blood vessels and adnexa, associated with epidermal hyperplasia, as well as orthokeratosis, parakeratosis and crusts. the follicular epithelium exhibited foci of spongiosis and exocytosis of neutrophils, with predominant chronic inflammation changes. bacterial culture identified staphylococcus intermedius, based on morphology, staining and biochemical tests positive for catalase, coagulase, glucose and aerobic acid production from mannitol. the equine was treated with dimethylsulfoxide, gentamicine and dexamethasone topically on a daily basis. although some lesions presented rapid regression (7 days), it took 13 months for the complete repair of those lesions of the neck and scapula.

Abstract: this paper deals with growth rates of trees > 5cm dbh over an eight-year period from 257 species at the tapajós national forest. the discussion is centred on the behaviour of the forest after logging. permanent sample plots were established in 1981 and measured at the first time. the area was logged in 1982. measurements after logging occurred in 1983, 1987 and 1989. considering all species together, diameter increment was similar for both intensities of logging until five years after logging. light-demanding species showed significantly higher growth rates than shade-tolerant species in the logged forest, with greater increment in the heavier treatment intensity. commercial species also had higher growth rates in the heavier logged area, although those were significantly different only in the period from one to five years after logging. in the undisturbed forest, growth rates increased with increasing dbh size. at species level, growth rate varied between and within treatments, as well as between trees within species, depending mainly on degree of canopy opening. the logging favoured the growth of commercial species, chiefly the light-demanders. therefore, if the same growth conditions continue being given, for example by silvicultural treatments, to those species of commercial interest, the forest would reach a stock available for harvesting around year 30 after logging. however, the high variation in increment rates indicates that an eight-year period is not sufficient to allow predictions on cutting cycles or polycyclic management systems for the study forest.

Abstract: The purpose of this experiment was to compare the performance of three strains of Nile tilapia, chitralada (T1), a common lineage (T2) and a mixed race (T3), in cages over a period of 98 days. The fish were stocked in nine cages with a volume of 1m3 each, where there were 200 fish/m3, in a pond that was 2,500m2 and 1.6m deep. The study had three replications, and the tilapia were fed a diet containing 32% crude protein with pellets that were 4-6mm. Measurements were made by sampling 20 fish/tank. Variables in water temperature, pH, dissolved oxygen and electrical conductivity were monitored weekly at 5am. We compared weight gain, feed conversion, biomass, specific growth rate and survival. The mixed race was not significantly different when compared to chitralada lineage, but when these two strains were compared to the common lineage, there was a significant difference for weight gain, specific growth and biomass. The feed conversion did not differ significantly between treatments (1.66; 1.68; 1.47). The survival of the mixed race did not differ when compared to the other strains; however, the chitralada lineage differed significantly from the common strain (97.67%; 94.00%). The results indicate that the mixed race adapted to the culture system evaluated.

Abstract: With the globalization process, the world-wide nations are having an increase of the international trade. Brazil has, each time more, used the agribusiness as a strategy of insertion in the world-wide economy. The exportations of Brazilian agricultural productscome playing an important paper in the supplying revenues and increase of the domestic income, but a visible problem of the agribusiness for exportation is related to logistic. In theworld-wide marketplace, Brazil presents comparative advantages in the production of agricultural products in relation to the other world-wide producers, but it loses in logistic costs. The importance of this work is in characterizing the logistic problems of the Brazilian exportation of one of the most important commodities national, the soybeans. The soybeans is the agricultural product that more generates volume of exportation for Brazil, demanding sufficiently of the logistic structure of the country. For accomplishment of this work, it was used an general bibliographical research, where if it carried through a detailed survey of themain problems, causes, costs and solutions for the flowing of the soybeans in Brazilian for exportation. From the development of this work, it was perceived that the challenges of the logistic of the soybeans are many and that the resolution of these problems will increase the Brazilian international competitiveness, increasing the trustworthiness in the delivery times and reducing the costs of the inefficiencies in the exportation process.

Abstract: Com o processo de globaliza o, as na es mundiais est o tendo um aumento do comércio internacional. O Brasil tem, cada vez mais, utilizado o agronegócio como uma estratégia de inser o na economia mundial. As exporta es de produtos agrícolas brasileiros vêm desempenhando um importante papel no fornecimento de divisas e aumento da renda doméstica, mas um problema visível da agroindústria para exporta o está relacionado à logística. No mercado mundial, o Brasil apresenta vantagens comparativas na produ o de produtos agrícolas em rela o aos outros produtores mundiais, mas perde em custos logísticos. A importancia deste trabalho está em caracterizar os problemas logísticos da exporta o brasileira de uma das mais importantes commodities nacional, a soja em gr o. A soja é o produto agrícola que mais gera volume de exporta o para o Brasil, exigindo bastante da estrutura logística do país. Para realiza o deste trabalho utilizou-se de uma ampla pesquisa bibliográfica, onde se realizou um levantamento detalhado dos principais problemas, causas, custos e solu es para o escoamento da soja em gr o brasileira para exporta o. A partir do desenvolvimento deste trabalho percebeu-se que os desafios da logística da soja s o muitos e que a resolu o dos mesmos aumentará a competitivi

Abstract: in view of the different managements used in coffee production, this study aimed to quantify the changes of some physical properties of an oxisol under four-year-old coffee, in southern minas gerais. three management systems were compared to native forest. the following management systems were evaluated: mechanized coffee production (ccm), coffee without mechanization (csm), dense coffee plantation (ca) and native forest (mn) as reference. undisturbed samples were collected with an uhland sampler and aluminum rings (diameter 6.35 cm, height 2.54 cm), from the layers 0-3 cm and 15-18 cm; in the latter the maximum mechanical resistance had been previously determined by a penetrometer. the coffee plantations were sampled at two points, i.e., in the wheel track and under the trees (canopy projection) under ccm and csm management, in-between coffee rows and under the trees under ca management, and randomly in native forest, with four replications, totaling 56 samples. the physical properties soil bulk density (bd), particle density (dp), soil resistance to penetration (rp), total pore volume (vtp), macroporosity (ma) and microporosity (mi) and ma/mi ratio were evaluated. the mechanized coffee system affected the physical properties in the wheel track, as indicated by increases in soil density and soil penetration resistance and reduced total porosity, macroporosity and ma/mi ratio, four years after planting. in the 0-3 cm layer, macroporosity and ma/mi ratio were lower in the mechanized coffee system and microporosity, and penetration resistance higher than in the deeper layer, four years after planting.

Abstract: although with potential to adapt in many regions of brazil, the triticale, a grass that produces grain and forage, has been used only in the south of the country. the objective of this work was to study the nutritive value of the triticale forage as well as the fermentation parameters and quality of its silage when it is grown in southeast region and cut at six different ages. the experiment was carried (07/07/95) out at guarani (minas gerais state, brazil). cutting ages studied were 73, 80, 87, 94, 101 and 108 days after sowing, using a casual design with four replications. there was an increase of 0.46 and a decrease of 0.09 percent units on dry matter (dm) and crude protein (cp) percentages, respectively, for each additional day in the cutting age. the highest values of dm were those obtained by plants cut between 87 and 101 days. quadratic relationship was observed between silage ph values and cutting ages, where ph values varied between 3.7 and 5.5, and the lowest acetic acid concentrations, between 1,93 and 3,60% of the dm. silage from plants cut after 73 days of age presented 0,97% of lactic acid in the dm. the highest (p<0,05) concentration of lactic acid was observed in silage produced from the plants cut at 94 growth days (12.05% of the dm). the in situ ruminal degradation parameters of fresh forage ranged from 74.6 to 89.5% (potential degradability), from 2.8 to 3.8%/h (degradation rate), and from 42.0 to 51.0% (effective degradability under 5%/h of passage rate). silage obtained from plants cut at 87, 94 and 101 growth days presented better nutritional quality.

Alfa : Revista de Linguística , 2009,
Abstract: O presente ensaio procura discutir as marcas enunciativas presentes na melodia tonal a partir da investiga o de algumas propriedades comuns ao aparelho fonador humano e aos instrumentos musicais reais e virtuais. Analisando essas propriedades à luz da teoria glossemática de Hjelmslev (1975) e da semiótica tensiva de Claude Zilberberg (2006), nossa investiga o chegou aos seguintes resultados: (i) dado que o sistema musical e o sistema fonológico possuem categorias comuns, pode-se sustentar a existência de um parentesco genético entre express o verbal e express o musical; (ii) o efeito de sentido característico da melodia tonal é fruto de uma confi gura o sintagmática de suprassegmentos (cronemas, tonemas e dinamemas) hierarquicamente organizados; (iii) outras categorias do sistema melódico tais como o andamento, a dinamica e o timbre – os foremas musicais – ocupam um papel à parte na hierarquia melódica e s o as principais responsáveis pelas marcas deixadas no enunciado pela instancia intérprete do sujeito da enuncia o.
