Abstract: In Paraíba, Brazil, a local market for family farming is the production of naturally colored cotton grown in agroecological regime. For solution of physicochemical and biological soil degradation of brazilian semiarid, where Caatinga biome predominates, one valuable agroecological practice is the organic adubation. Accordingly, it was aimed with the present work to study the influence of bovine manure doses (D0 - 0.0; D1 - 2.5; D2 - 5.0; D3 - 10.0; D4 - D5 and 20.0 - 40.0 Mg ha-1) on agronomic and fiber characteristics of the agroecological herbaceous cotton BRS Rubi crop in the arid region of that State, in the years 2008/2009 and 2009, and to define the best dose of this organic fertilizer for this system and this growing region. The treatments were arranged in a randomized block design, with four replications. It was performed combined analysisof variance of the experiments, being evaluated agronomic (stem diameter, plant height, yeild and boll weight) and fiber(percentage, length, strength, micronaire index, fiber short index, elongation and maturity of fibers) variables in the two yearsof cultivation. It was concluded that: there was influence of the bovine manure doses tested for the agronomic characteristicsbut not for the characteristics of the fibers of the herbaceous cotton colored BRS Rubi; the best dose was 18 Mg ha-1of bovinemanure (Maximum Economic Dose). = Na Paraíba, um nicho de mercado para a agricultura familiar é a produ o de algod o naturalmente colorido ecultivado agroecologicamente. Para solu o da degrada o físico-química e biológica dos solos do semiárido brasileiro, onde o bioma caatinga predomina, uma prática agroecológica valiosa é a aduba o organica. Nesse sentido, objetivou-se com o presente trabalho estudar a influência de doses de esterco bovino (D0 - 0; D1 - 2,5; D2 - 5; D3 - 10; D4 - 20 e D5 - 40 Mg ha-1) sobre características agron micas e da fibra do algodoeiro herbáceo colorido BRS Rubi, sob cultivo agroecológico no Sert o Paraibano, durante dois anos agrícolas (2008/2009 e 2009), e definir a melhor dose deste fertilizante organico para este sistema e regi o de cultivo. Os tratamentos foram dispostos em um delineamento experimental de blocos casualizados, com quatro repeti es. Foi realizada análise conjunta dos ensaios, sendo avaliadas variáveis agron micas (diametro caulinar, altura daplanta, produtividade e peso dos capulhos) e das fibras (percentagem, comprimento, índice de fibras curtas, resistência, finura,alongamento e maturidade das fibras) nos dois anos de cultivo. Concluiu-se que houve influência das dose

Abstract: in this paper, result of studies conducted in piracicaba, s?o paulo, brazil, the authors made observations about the position of the buds at the base of the leaf sheaths to which they are associated. they used the banana plant variety musa (aaa group, cavendish sub-group) "nanic?o", classified according to simmonds' nomenclature (1966). the following conclusions were drawn :(1) the buds at the base of the leaf sheaths are found on the left, at lateral position on the sheaths. (2) the right side of the sheaths covers the younger buds which are placed more internally on the banana stem. (3) the position of the buds in the banana stem is a function of the phyllotaxy of the plant.

Abstract: using ip-resistivity soundings it is possible to define the structural geometry and the lithological variability within the urucuia aquifer in the rio das fêmeas basin, bahia. a total of 80 schlumberger ves, measuring simultaneously the electrical resistivity and the time domain chargeability, were performed within this hydrological basin to a maximum current electrode spacing (ab/2) of 1000 m. contour maps of the depth to the aquifer substratum, the depth to the phreatic surface, the mean aquifer resistivity (r), and the upper aquifer polarization (ms) were constructed after the quantitative inversion of the soundings. the aquifer consists of stacked sandstone bodies forming layers of different resistivity overlaying a much more conductive regional shaly substratum. high values of r and ms, for the aquifer model suggest it is dominantly composed of shaly sandstones but saturated with very fresh groundwater. the reservoir thickness increases from east to west, ranging from about 100 m in the middle of s?o desidério county to more than 450 m at the edge of the serra geral scarps. the general groundwater flow is from west to east, except in a small portion near the scarps were it is reversed forming a groundwater divide inside this hydrological basin. the jointly inversion of the ip and resistivity data was useful to reduce geoelectrical ambiguities and to better define the water table depths. the achieved results are of great value for planning a sustainable water exploration program for the region, which is being stressed by an accelerated agricultural development.

Abstract: there a trend toward the evaluation of higher education in many countries, taking into account institutional management and student performance. in brazil, the topic has been debated for some time with concrete evaluation experiences recently. federal universities (ifes) are evaluated through management indexes proposed by tcu (federal court of audit). meanwhile, students are evaluated by enade (national examination of student performance). in a certain way, management indexes may be additional instruments for ifes management. the purpose of this work is analyzing possible relations between management indexes and students' performance at enade. we have analyzed a sample of 52 ifes in the period 2006-2008. results signal that, indeed, some management indexes seem to be able to influence students' performance. this is the case, for example, of the cost by student that has shown a positive effect on students' performance.

Abstract: O presente trabalho teve o objetivo de analisar os efeitos do enxofre e da chuva ácida simulada sobre a estrutura foliar do feijoeiro (Phaseolus vulgaris L), nos aspectos morfoanat micos, teores de clorofila a, b, total e feofitina. As plantas-controle sofreram simula es de chuva com pH 6,0 e as plantas-teste sofreram simula o de chuva ácida com pH 3,0. As concentra es de clorofila a, b e total diminuíram no estádio de flora o (R6). Já, no estádio R7, onde surgem as primeiras vagens, os teores aumentaram, indicando possível resistência e/ou adapta o dos espécimes às simula es ácidas. O tratamento ácido afetou a concentra o de clorofila que foi degradada por processos oxidativos sem a sua convers o em feofitina. Também se observou diminui o na frequência de tricomas tectores e glandulares, assim como de est matos. As injúrias visualizadas foram classificadas como de caráter leve, provavelmente pela existência de anexos epidérmicos para prote o foliar e peciolar. The goal of this work was to evaluate the effects of sulfur and simulated acid rain on the leaf of Phaseolus vulgaris. Acid rain (pH 3.0) and an aqueous solution (Ph 6.0) were performed on test and control plants, respectively. A decrease in chlorophyll a, chlorophyll b and total chlorophyll concentrations was observed in theflowering stage (R6). However, increased rates were determined in the maturation stage (R7), which can suggest a resistance and/or adjustment of the plants to the acid simulation conditions. The acid treatment achieved chlorophyll degradation by oxidative processes without conversion to pheophytin. A reduction was also seen in the number of glandular and non-glandular trichomes and stomata on the test plants. Moreover, only small injuries were verified on the blade and peciolar areas of the tested individuals of P. vulgaris, probablydue to the presence of the reported epidermal structures.

Abstract: Arthritic lesions have been frequently diagnosed in the fossil record, with spondyloarthropathy (a type of erosive and pan-mammalian arthritis) being one of the most common types described to date for mammals, though not restricted to this group. Here, we identify spondyloarthropathy in fossil bones from the late Pleistocene in Brazil assignable to a large glyptodont individual. Bone erosions in the peripheral joints (viz., the ulna, radius, left femur and tibiae-fibulae) associated with osteosclerosis allow the diagnosis of spondyloarthropathy. The presence of osteophytes in seven bones of the forelimbs (viz., the ulna and radius) and hind limbs (viz., the tibiae-fibulae, left femur and patellae) and a subchondral cyst in one element (viz., the left femur) indicate secondary osteoarthritis. A calcified deposition on the articular surface of the left patella indicates the presence of calcium pyrophosphate deposition disease, which, like the observed osteoarthritic alterations, likely represents a complication of spondyloarthropathy. This is the first report of spondyloarthropathy for xenarthrans.

Abstract: this paper aims to revisit the intergenericity, a concept that deals with genre mixture. based on bakhtin's reflections (2006 [1953]) on reelaboration and genre mixture, we seek arguments to support the thesis that the concept of intergenericity, as it has been proposed by text linguistics, does not account for all the different forms of text in which genres are mixed. we propose three different types of genre mixture: the prototype intergenericity mixture, characterized by the fusion of traces of, at least, two genres; the casually occurring genre mixture; that consists of genres that do not necessarily combine, but that coexists in a symbiotic relationship, considering a common communicative purpose; and the interspersed genre mixture, which involves genres that can belong to different enunciative scenes.

Abstract: according to some estimates, world's population growth is expected about 50% over the next 50 years. thus, one of the greatest challenges faced by engineering is to find effective options to food storage and conservation. some researchers have investigated how to design durable buildings for storing and conserving food. nowadays, developing concrete with mechanical resistance for room temperatures is a parameter that can be achieved easily. on the other hand, associating it to low temperature of approximately 35 °c negative requires less empiricism, being necessary a suitable dosage method and a careful selection of the material constituents. this ongoing study involves these parameters. the presented concrete was analyzed through non-destructive tests that examines the material properties periodically and verifies its physical integrity. concrete with and without incorporated air were studied. the results demonstrated that both are resistant to freezing.
