Asymptomatic Intrahepatic Portosystemic Venous Shunt: Case Report and Review of Literature  [PDF]
Huylmer Lucena Chaves, Mayanna Pinho Batista, Germana Bastos Pontes, Lia Pontes de Melo, José Carlos Godeiro Junior
Open Journal of Radiology (OJRad) , 2019, DOI: 10.4236/ojrad.2019.91001
Abstract: A spontaneous portosystemic shunt is a rare malformation of the liver vessels. The etiology of these shunts is controversial. They can be divided into acquired (most commonly associated with liver cirrhosis) and congenital. Vascular shunts are asymptomatic in the majority of the patients, and when symptomatic were presented by severe complications. The specific way of management can be selected depended on whether the patient was symptomatic or not, and also on the size of the shunt, shunt ratio and whether it was associated with cancer. We will present a clinical case and discuss the importance of the radiological imaging in the screening, diagnosis and follow up of these anomalies.

Abstract: the objective of this work was to analyze the accuracy of piling factor estimates using digital photography and software especially developed for this purpose. six trucks carrying five piles each, owned by acesita energética ltd., were used in this research. the analysis revealed that the average difference between the factors determined by the photographic method and the actual factors was approximately 3.2%, with a tendency for over estimation of the values obtained by the photographic method. the "t" test analysis suggested that the differences observed between these factors were mainly due to the the poor piling up of the wood.

Abstract: O objetivo deste trabalho foi analisar a exatid o de estimativas de fatores de empilhamento obtidas através de fotografias digitais e de software especialmente desenvolvido para esta finalidade, em pilhas sobre caminh es. Para isto, foram utilizados seis caminh es com cinco pilhas cada um, pertencentes à ACESITA ENERGéTICA Ltda. Após as análises, verificou-se que a diferen a média entre os fatores obtidos pelo método fotográfico e os fatores reais foi da ordem de 3,2%, com tendência de superestima o dos fatores obtidos pelo método fotográfico. Pelo teste "t", verificou-se, também, que os fatores obtidos pelo método fotográfico diferiram dos fatores reais, principalmente devido ao mau empilhamento da madeira.

Abstract: when it comes to the planning of public policies linked to the rural development, finding a definition of concepts of rural and urban environments and also of cooperative becomes essentially important. considering that psychology has barely little contributed to the rural development, this study aimed at identifying the meanings which are socially given to the mentioned concepts. with a sample of 318 high school students from paraíba (brazil), it was observed that the rural construct conveyed meanings essentially related to the rural atmosphere; the urban environment was conceived as being the opposite of rural and the concept of cooperative carried a positive meaning, having within it words like 'help' and 'union'. critical thoughts over the policies for the rural development are urged and so are further studies in the area which may contribute to clarify aspects related to the development of proposals for the rural environment in its totality. the review of some concepts is provided and also the evaluation of some government actions through public policies.

CERNE , 2012,
Abstract: This research was carried out in a Pinus elliottii plantation, established in 1984, located in the Rio Negro Forest Research Station- Rio Negro – Paraná, owned by the Paraná Federal University, Paraná State, Brazil. The research objectives were to analyze the correlations between the FMA and FMA+ fire danger indices and the fine fuel moisture, and develop mathematical models to estimate the fuel moisture based on these indices. The meteorological variables were obtained from a SIMEPAR weather station, located 50km away, and from a pluviograph and a thermo-hygrograph installed in the study area. The dead forest fuels were collected from 30x30cm plots, between 12 noon and 2:00PM, and classified as: AA – surface layer; AB – intermediate layer; AC – lower layer; and B -woody material with 0.7 to 2.5cm diameter. The total fuel load varied from 3185.50 to 4266.01g.m-2. The fire danger indices were daily calculated and the values obtained in the fuel colleting days were used to calculate the correlations. The correlation coefficients between relative humidity and fuel classes were 0.42; 0.36; 0.32; and 0.41 for the AA, AB, AC, and B classes, respectively. The correlation coefficients between precipitation and fuel classes were 0.57; 0.38; 0.34; and 0.15 for the AA, AB, AC, and B classes, respectively. The correlation coefficients between the fuel classes and the FMA+ were -0.53; -0.56; -0.63; and 0.81 for the classes B, AB, AA, and AC, respectively. The FMA+ was the most efficient variable in modeling development to estimate dead forest fuel moisture.

Renato Fernandes Amabile,José Garcia,Jo?o Batista Duarte,José Carlos S. Silva
Pesquisa Agropecuária Tropical , 2007, DOI: 10.5216/pat.v25i1.2737
Abstract: O feij o bravo-do-ceará é um dos adubos verdes mais promissores para os cerrados. Essa espécie fornece nitrogênio às culturas subseqüentes e possui excelente produ o de matéria seca. Por outro lado, mesmo sob condi es ambientais favoráveis, muitas sementes n o germinam devido ao tegumento impermeável, o que dificulta o estabelecimento de culturas. Este trabalho objetivou identificar formas de superar a dormência das sementes, por diversos métodos de escarifica o: a) remo o manual da por o distal das sementes (com e sem embebi o em água destilada); b) imers o das sementes em água a 1000oC por 30, 60, 180, 300 e 600 segundos; c) imers o das sementes em H2SO4 P.A. por 5, 10, 15, 20, 30, 40, 50 e 60 minutos; d) choque térmico (24 horas a 250oC, seguido de 24 horas a 50oC ou 400oC, com retorno a 250oC; e) imers o das sementes em álcool por 5, 15, 30 e 60 minutos; e testemunha. O delineamento experimental foi inteiramente ao acaso, com oito repeti es. Os tratamentos mais eficientes foram remo o da parte distal do tegumento (com e sem embebi o), imers o em ácido sulfúrico por 60 minutos e imers o em água a 1000oC por 60 e 30 segundos, com germina es, respectivamente, de 96,6%, 99,2%, 95,9%, 95,1% e 94,8%. PALAVRAS-CHAVE: Leguminosa; adubo verde; cerrado. Canavalia brasiliensis has a great potential as green manure in Brazilian Savanna. The species gives nitrogen to subsequent crops and produces excellent dry matter. On the other side, even under suitable environment conditions, several seeds don’t germinate due to the impermeable seed coat. This trial aimed to identify different treatments for dormancy breaking. Some scrub methods were tried: a) manual removal of distal portion of the seed, with or without distilled water soaking; 19 seed immersion on boiling water for 30, 60, 180, 300 and 600 seconds; e) seed immersion on H2SO4 for 5, 10, 15, 20, 30, 40, 50 and 60 minutes; d) thermal impact (24 h at 25 0C followed by 24 h at 5°C or 40°C, then returning to 25°C); e) alcohol immersion for 5, 15, 30 and 60 min.; f) control. Treatments that provided better germination were: removal of distal portion with and without water soaking (99.6 and 99.2% germination, respectively), H2SO4 for 60 min. (95.9%) and boiling water for 60 and 30 sec (97.7 and 94.8% germination, respectively). KEY-WORDS: Green manure; savanna; leguminosae.

Brazilian Archives of Biology and Technology , 2009, DOI: 10.1590/S1516-89132009000300004
Abstract: the corn plants were evaluated with different phosphate fertilizer sources and aluminum (al) concentrations in a sandy substrate. a totally randomized experiment design was set up with two corn plants in the pots containing 2 kg of a sandy substrate, two phosphate sources (triple super phosphate - tsp or arad phosphate - ap) and four al concentrations. when al concentrations increased, ph (cacl2) substrate values decreased. there was an increase in the calcium and phosphorus contents in the sandy substrates that received the tsp and ap sources. the calcium, magnesium, phosphorus, and potassium concentrations of the corn plant's shoot were higher in the tsp than without p and ap sources. when the al concentration increased, the concentration values of the former elements decreased. the dry mass production of the corn plants responded positively to p sources. as the al concentration increased, the dry mass values decreased significantly in the tsp source.

Abstract: the aim of this study was to evaluate the polymerization shrinkage and shrinkage stress of composites polymerized with a led and a quartz tungsten halogen (qth) light sources. the led was used in a conventional mode (cm) and the qth was used in both conventional and pulse-delay modes (pd). the composite resins used were z100, a110, surefil and bisfil 2b (chemical-cured). composite deformation upon polymerization was measured by the strain gauge method. the shrinkage stress was measured by photoelastic analysis. the polymerization shrinkage data were analyzed statistically using two-way anova and tukey test (p<0.05), and the stress data were analyzed by one-way anova and tukey's test (p<0.05). shrinkage and stress means of bisfil 2b were statistically significant lower than those of z100, a110 and surefil. in general, the pd mode reduced the contraction and the stress values when compared to cm. led generated the same stress as qth in conventional mode. regardless of the activation mode, surefil produced lower contraction and stress values than the other light-cured resins. conversely, z100 and a110 produced the greatest contraction and stress values. as expected, the chemically cured resin generated lower shrinkage and stress than the light-cured resins. in conclusion, the pd mode effectively decreased contraction stress for z100 and a110. development of stress in light-cured resins depended on the shrinkage value.
