Abstract: Forestry plantations should be regarded as an alternative sustainable land-use system in degraded savannah areas. They contribute to the maintenance of productive processes in degraded soils that are of economic importance for local inhabitants; in addition, in the ecological sense, timber and non-timber products from planted forests reduce the exploitation pressure on native forests. Eucalyptus plantations on degraded savannahs in the northern Brazilian Amazon may help to reduce exploitation pressure on native forests. However, there is no information regarding the nutrients rates that would allow faster eucalyptus growth in that region. A trial was installed in an Yellow Latosol (Oxisol) soil type adopting a one-half-type fractionalfactorial design with four rates of N, P, and K. Functions were adjusted for the dependent variables height, diameter at breastheight (DBH), leaf tissue nutrient content, and soil-chemical attributes. Interaction N versus K was observed on tree heightwith a maximum of 7.8 m recorded at 200 kg ha-1 of N and 50 kg ha-1 of K. Phosphorus fertilization promoted greater DBH growth with maximum value at 120 kg ha-1 of P; however, the highest gain was obtained at 30 kg ha-1 of P. The NPK rates that maximized Eucalyptus camaldulensis growth were 200, 30, and 50 kg ha-1, respectively. Planta es de eucalipto, em áreas de lavrado degradadas na Amaz nia Setentrional brasileira, devem contribuir para diminuir a press o de explora o em florestas nativas. Porém, n o há informa es sobre as doses de nutrientes que permitem o rápido crescimento do eucalipto nesta regi o. Um experimento para avaliar a resposta à aduba o do Eucalyptus camaldulensis foi instalado em Latossolo Amarelo, adotando o delineamento fatorial fracionário com quatro doses de nitrogênio (N), fósforo (P) e potássio (K). Fun es foram ajustadas para as seguintes variáveis dependentes: altura, diametro à altura do peito (DAP), conteúdo de nutrientes nas folhas e atributos químicos do solo. Foi observada intera o NxK para a altura, com um máximo de 7,8 metros registrados com a dose de 200 kg ha-1 de N e 50 kg ha-1 de K. A aduba o fosfatada promoveu o maior crescimento do DAP com o valor máximo obtido com a dose de 120 kg ha-1 de P; O maior ganho, entretanto, foi obtido com a dose de 30 kg ha-1 de P. As doses de NPK que maximizaram o crescimento do Eucalyptus camaldulensis foram 200, 30 e 50 kg ha-1, respectivamente.

Abstract: O presente trabalho foi desenvolvido no “Projeto Ipiranga VII”, localizado na Fazenda Boa Vista no município de Encruzilhada do Sul, RS, pertencente a Empresa Ipiranga Florestal Ltda. O projeto foi implantado em 1987, tendo uma área total e efetivo plantio com Pinus elliotii de 311,59 ha e 200 ha, respectivamente. Este trabalho teve como objetivo determinar as características distintas da área em estudo (sítios) em fun o dos fatores edáficos, dendrométricos e da vegeta o. O sítio I apresentou uma colora o bruno avermelhado escuro (5YR úmido) na profundidade de 0-10 cm. Este sítio possui solos rasos, apresentando uma profundidade inferior a 20 cm, a superfície do solo apresenta muitas pedras e pedriscos, textura arenosa a franco argilosa e estrutura granular grumosa. O sítio II possui uma colora o bem escura, diferenciando nitidamente do sítio I, pois na profundidade de 20-40 cm apresentou uma colora o bruno avermelhado escuro (5YR 2,5/2 úmido). Neste sítio o solo possui uma profundidade média a profunda, sendo que na maioria dos pontos de sondagem a profundidade do solo foi superior a 40 cm. A superfície do solo neste sítio apresentou poucas pedras e pedriscos, possuindo estrutura granular poliédrica a blocos subangulares e textura franco arenosa. Apesar do sítio I ter menor número de árvores por hectare, em torno de 120 árvores a menos que do sítio II, estas possuem um diametro basal médio menor que no sítio II, pois sabe-se que o diametro é diretamente influenciado pela densidade do povoamento, quanto mais denso for o povoamento, menor será o diametro do mesmo. A área basal média por hectare no sítio I foi de 32,40 m2/ha e 37,91 m2/ha para o sítio II, tendo uma diferen a de 5,51 m2/ha. Visto que o Projeto Ipiranga VII possui dois sítios, percorreu-se toda a área com o objetivo de coletar amostras de solos em diferentes profundidades, que variam de 0 a 20 cm e de 20 a 40 cm, isto nos sítios I e II. A análise do solo revelou que o sítio II possui maior percentagem de matéria organica em ambas profundidades, podendo justificar a colora o mais escura do solo e mais disponibilidade de nitrogênio e outros nutrientes às plantas. Os dois sítios em ambas profundidades s o muito ácidos, tendo uma necessidade média de calcário de 4,9 t/ha, pela tabela SMP, para atingir um pH de 5,5 o que seria ideal para Pinus e Eucalyptus. Essa acidez é refletida pelos teores de alumínio, ficando em torno de 1,0 meq/100 ml, com tendência de aumentar à medida que aumenta a profundidade de amostragem. A menor percentagem de argila foi encontrada nas profundidades 20-40 cm

Abstract: the aim of this study was to evaluate the effects of acacia mangium plantation in the roraima's savanna, on soil organic carbon and soil microbial biomass. soil samplings were collected on the depths of 0-20 cm and 20-40 cm in two acacia mangium plantation sites, about five years old, and in two sites of native savanna as reference. one of the a. mangium sites (located at fazenda cigolina) was composed by a homogeneous plantation (3.6 m between row and 2.0 m between trees) and, the other one (located at campo experimental agua boa experimental - ceab) was composed by a plantation on which the planting distances had strips of two rows 6 meters apart, 2.5 meters between trees and 30 meters between strips). soil samples were analyzed regarding soil organic carbon, microbial biomass carbon, soil basal respiration and metabolic quotient, besides soil fertility attributes. results showed that a. mangium plantations did not provide significant increases of organic carbon on the soil comparing with sites used as reference. however, generally, a. mangium plantation increased soil microbial biomass carbon and reduced metabolic quotient, indicating a possibility of soil organic carbon accumulation in long-term. it was also observed that, soil biomass microbial carbon was higher, followed by smaller metabolic quotient at ceab a. mangium plantation compared with cigolina and reference sites, showing that planting design exercised influence on soil microbial biomass.

Abstract: We studied the reproductive biology of Astyanax scabripinnis by monitoring oocyte development of 94 adult females. Microscopic analysis of the ovaries, gonadosomatic and hepatosomatic indeces assessment, visceral fat and condition factor evaluations were carried out. The structures observed in the ovaries were described from the histological analysis and the hepatosomatic índex, which were used to determine the involvement of the liver in the development of oocytes of this species. Oogonia, oocyte I and oocyte II were present in all stages of gonadal development. Oocytes with cortical vesicles were present in large quantities in the intermediate stage of maturation (F2B) and in a lesser amount in the final stages of maturation (F2C). Mature oocytes were common in the intermediate stage of maturation (F2B), but prevailed in the final stages of maturation (F2C). Oocytes in final maturation and mature viable oocytes, many atresic and post-ovulation folicles were found in spawned animals, besides the ovary disorganization, which are strong characteristics of spawing. Spawned animals were found throughout the year, showing that the species presents a kind of intermittent spawning.
Respuesta barotrópica de los golfos norpatagónicos argentinos forzados por mareas y vientos
Tonini,Mariano H; Palma,Elbio D;
Latin american journal of aquatic research , 2011,
Abstract: this work presents the results of a high resolution three dimensional non-linear barotropic hydrodynamic model used to examine the response of three north patagonian gulfs in argentina (san matías, smg; nuevo, ng; and san josé, sjg) forced by tides and idealized patterns of surface winds. the structure of the circulation induced by the dominant winds (westerly) in all three gulfs consists of two independent gyres: one anticyclonic gyre in the west with an intense southward coastal flow and weaker return flow in the middle of the gulfs and one cyclonic gyre in the east that, in the smg's case, connects with the shelf. the other two gulfs (ng and sjg) have much more restricted connections with the exterior. the inclusion of tidal dissipation effects reduces the intensity of the gyres, but the general spatial pattern of the circulation remains. increasing the wind magnitude mainly intensifies the anticyclonic gyre and the cross-shelf transport through the smg mouth and deepens the surface ekman layer. if the gulfs are forced with meridional winds, the circulation splits into two gyres whose sense of circulation depends on the wind direction: a northern cyclonic (anticyclonic) gyre and a southern anticyclonic (cyclonic) gyre for southerly (northerly) winds. when the gulfs are forced simultaneously by tides and winds, the residual tidal currents dominates the general circulation and contributes to a greater dynamical isolation of the gulfs from the exterior shelf.
Respuesta barotrópica de los golfos norpatagónicos argentinos forzados por mareas y vientos Barotropic response of north Patagonian gulfs in Argentina to tidal and wind forcing
Mariano H Tonini,Elbio D Palma
Latin american journal of aquatic research , 2011,
Abstract: En este trabajo se presentan los resultados de un modelo hidrodinámico barotrópico de alta resolución no-lineal tridimensional para examinar la respuesta de los golfos norpatagónicos argentinos, San Matías (GSM), Nuevo (GN) y San José (GSJ), ante forzante de marea y patrones idealizados de viento superficial. La estructura de la circulación inducida por el viento predominante (Oeste) en los tres golfos consiste en dos giros independientes: uno anticiclónico en el Oeste con una corriente costera más intensa que fluye hacia el sur y un retorno más débil por el centro de los golfos y otro giro ciclónico en el Este, que establece la conexión con la Plataforma en el caso del GSM. El GN y GSJ tienen la comunicación con el exterior muy restringida. La inclusión de efectos disipativos producidos por la marea reduce la intensidad de los giros, pero la estructura espacial de la circulación permanece. Si se incrementa la magnitud del viento se intensifican principalmente los giros anticiclónicos y el transporte de intercambio en la boca del GSM y se profundiza la capa superficial de Ekman. En los experimentos forzados con vientos meridionales la circulación media se divide en dos giros cuyo sentido de circulación depende de la dirección del viento: un giro Norte ciclónico (anticiclónico) y un giro Sur anticiclónico (ciclónico) para vientos del Sur (Norte). Cuando los golfos son forzados simultáneamente por marea y vientos, las corrientes residuales de marea dominan la circulación media y contribuyen a un mayor aislamiento dinámico de los mismos con la plataforma exterior. This work presents the results of a high resolution three dimensional non-linear barotropic hydrodynamic model used to examine the response of three north Patagonian gulfs in Argentina (San Matías, SMG; Nuevo, NG; and San José, SJG) forced by tides and idealized patterns of surface winds. The structure of the circulation induced by the dominant winds (Westerly) in all three gulfs consists of two independent gyres: one anticyclonic gyre in the west with an intense southward coastal flow and weaker return flow in the middle of the gulfs and one cyclonic gyre in the east that, in the SMG's case, connects with the shelf. The other two gulfs (NG and SJG) have much more restricted connections with the exterior. The inclusion of tidal dissipation effects reduces the intensity of the gyres, but the general spatial pattern of the circulation remains. Increasing the wind magnitude mainly intensifies the anticyclonic gyre and the cross-shelf transport through the SMG mouth and deepens the surface Ekman laye

Abstract: This is a retrospective study on gigantomastia correction in obesity facing the technique of nipple-areolar grafts and its complexity. The main question is the technical-surgical care during its execution aiming to achieve reparative results that can return to these women the desire to live with better quality of life and health. Method: We performed a retrospective study of all obese patients with severe gigantomastia who underwent reduction mammaplasty with an operative technique using the superior pedicle, with special care for the nipple-papillary grafts. The study was carried out at a single institution between 2001 and 2013, in a total of 30 cases. This operative technique was presented at first time in 1980, with no changes up to now. We emphasized the perfect decortication of the areola and nipples until they were translucent after the maneuvers of Schwartzman and subsequent grafts operated in both breasts. Results: Results were considered satisfactory, from the reparative and aesthetic point of view, emphasizing the degree of improvement observed in women undergoing technique. Discussion: We can say that during all this time of aesthetic and therapeutic-restorative surgery, due to its realization in a single surgical time, there was big impact on the aesthetics of patients and on their families, even taking into account possible complications in the post-operative. Conclusion: The superior pedicle technique, performed as described here, is a safe and reliable procedure in patients with severe gigantomastia.

Abstract: Reducing dependence on fossil fuels and mitigation of GHG emissions is a main focus in the energy strategy of many Countries. In the case of Demark, for instance, the long-term target of the energy policy is to reach 100% renewable energy system. This can be achieved by drastic reduction of the energy demand, optimization of production/distribution and substitution of fossil fuels with biomasses. However, a large increase in biomass consumption will finally induce conversion of arable and currently cultivated land into fields dedicated to energy crops production determining significant environmental consequences related to land use changes. In this study the global warming potential impact associated with six alternative bioenergy systems based on willow and Miscanthus was assessed by means of life-cycle assessment. The results showed that bioenergy production may generate higher global warming impacts than the reference fossil fuel system, when the impacts from indirect land use changes are accounted for. In a life-cycle perspective, only highly-efficient co-firing with fossil fuel achieved a (modest) GHG emission reduction.

Abstract: galactomannans are storage cell wall polysaccharides present in seeds of some legumes. their degradation is carried out by three hydrolases (a-galactosidase (ec 3.2.1.22), endo-b-mannanase (ec 3.2.1.78) and ?-mannosidase (ec 3.2.1.25)). in the present study we purified and characterised an endo-b-mannanase from seeds of sesbania virgata and addressed its role in germination and seedling development. the polypeptide purified by ion exchange chromatography and affinity chromatography on sepharose-concanavalin a, showed a ph optimum between 3.5 and 5 at 45oc and high stability at ph 7.8. the low stability at ph 5 appears to be associated with isoelectric precipitation, in view of the pi of the enzyme being 4.5. the purified enzyme is a glycoprotein with a molecular mass of 26 kda by sds-page and 36 kda by gel chromatography. the purified polypeptide attacked galactomannan from different sources, being more effective on polymers with a lower degree of galactosylation (from carob gum), in comparison with medium or highly galactosylated galactomannans (from guar, s. virgata and fenugreek), respectively. a peak of endo-b-mannanase activity was detected during radicle protrusion in the endosperm tissue surrounding the radicle and later on in the lateral endosperm. this second peak was associated with the period of reserve mobilisation. using an antibody raised against coffee endo-b-mannanase, the enzyme could be detected in immunodot-blots performed with extracts of s. virgata endosperms. the results are consistent with the hypothesis that the peak of endo-mannanase during germination facilitates radicle protrusion through the surrounding endosperm by weakening it in the region close to the radicle tip.
