Abstract: human herpesvirus type 6-(hhv-6) has been associated with morbidity after liver transplantation. objective: the aim of this study was to determine the hhv-6 seroprevalence among donor-recipient pairs, analyze the incidence of early active infection, its clinical manifestation, interaction with cmv, and the related morbidity in the first year after kidney transplantation. methods: 46 donor-recipient pairs had igg evaluated by elisa before transplantation: hhv-6(pambio - usa) and cmv-(roche - usa). a frozen whole blood sample collected weekly (from the 1st to the 6th week) was retrospectively tested for hhv-6 viral load (vl) determination by real time quantitative pcr (qpcr, nanogen - italy). patients were preemptively surveyed for cmv by pp65 antigenemia (ag, apaap, immunohistochemistry, biotest - germany) from the 4th to the 12th week after transplantation. active infection was defined as qpcr-hhv6+ (viral-load/ml-vl) and ag+ (+cells/100.000 granulocytes), for hhv-6 and cmv, respectively. dcmv was defined as simultaneous positive antigenemia and suggestive signs/symptoms. concerning +qpcr-hhv6, associated factors, clinical manifestation, interaction with cmv and morbidity were searched. results: pre-transplant hhv-6 seroprevalence was significantly higher among kidney recipients compared to their donors (82.6x54.8%; p = 0.005 [3.9 (1.4-10.4)]). active infection by this virus occurred in 26.1% (12/46), with no association with previous igg (p = 0.412). median vl was 125 copies/ml (53-11.264), and the median ag was 21 +cells (2-740). there was no association between hhv-6 and cmv activation after transplantation (p = 0.441), neither concerning dcmv (p = 0.596). median highest ag+ and days of ganciclovir treatment were similar between qpcr-hhv6 + or - (p = 0.206 and p = 0.124, respectively). qpcr-hhv6+ was associated with higher incidence of bacterial (p = 0.009) and fungal (p = 0.001) infections, and higher number (p = 0.001) of hospital admission and longer duration

Abstract: this study evaluated the influence of nitrogen levels (n) and plant density (d) on the tillering dynamics of tanzania guinea grass (panicum maximum jacq.). treatments were arranged in a completely randomized block design with 12 treatments and two replicates in a factorial scheme (4 × 3) with four levels of n (0, 80, 160 or 320 kg ha-1 n) and three plant densities (9, 25, and 49 plant m-2). higher number of tillers was observed in the treatment with 9 plants m-2 and under higher levels of n, especially in the second and third generations. still, the n influenced quadratically the appearance rate of basal and total tillers, which were also affected by plant density and interaction n × d. however, the appearance rate of aerial tiller was not influenced by factors evaluated. the mortality rate of total tiller was influenced quadratically by the nitrogen levels and plant densities. the mortality rate of basal tiller responded quadratically to plant density, whereas the mortality rate of aerial tiller increased linearly with fertilization. pastures with low or intermediate densities fertilized with nitrogen, presented a more intense pattern of tiller renewal.

Revista Brasileira de Zootecnia , 2012, DOI: 10.1590/S1516-35982012000500006
Abstract: the objective of this study was to evaluate the effect of different levels of nitrogen supply and plants densities in the productivity of mombasa guineagrass (panicum maximum) in the period of establishment. the design was of completely randomized blocks, with 12 treatments and three repetitions, with four nitrogen supplies (absence of application, 80, 160 and 320 kg/ha.year) and three plant densities (9, 25 and 49 plants/m2). the plot was cut at 30 cm from the ground when the sward high intercepted 95% of light. the following items were evaluated: sward height at 95% light interception, interval and number of cuts, dry mass production, total dry mass of leaves, stems and dead material and the morphologic composition. nitrogen increased the dry mass production and the dry mass of stem in winter and summer, and decreased in the fall. the total dry mass of leaf presented decrease of 19% in the summer between the smallest and biggest densities in the 320 kg/ha. the dry mass of dead material had negative effect of the density in the fall. the leaf percentage increased 88% between the smallest and largest nitrogen level at the plant density of 49 plants/m2. only density influenced the sward height in the condition of 95% of light interception. the number of cuts increased with nitrogen levels in the fall, spring and summer, while the interval of cuts decreased with fertilization in the spring and summer. nitrogen increases the production of mombasa guineagrass in each cycle.

Revista Brasileira de Zootecnia , 2012, DOI: 10.1590/S1516-35982012000400006
Abstract: the objective of this experiment was to evaluate the nitrogen and plant density influence on the yield, forage dissection and nutritive value of tanzania grass (panicum maximum jacq.). the design was of completely randomized blocks with three replications in a factorial arrangement with four nitrogen levels (0, 80, 160 or 320 kg/ha n) and three plant densities (9, 25 or 49 plants/m2). the plots were cut at 25 cm from soil level when the canopy reached 95% of light interception. the total dry matter forage yield and dry matter forage yield per harvest increased linearly with the nitrogen fertilization. the leaf and stem yield had the same response. the senesced forage yield was quadratically influenced by the nitrogen. the stems ratio in the morphologic composition was high in the high nitrogen levels and in the low plant densities. the leaf:stem ratio showed high values in this trial, but it was increased in plots without nitrogen and high plant density. the pre-grazing height was reduced with the increase in plant density. the nutritive value was favored by the nitrogen fertilization, which increased the crude protein level and reduced neutral detergent fiber and lignin. these factors increased the leaf and stem in vitro digestibility of organic matter. nitrogen fertilization increases the forage yield of tanzania grass under rotational grazing. after the establishment, plant density has little influence on the tanzania grass yield and its forage dissection. the harvest with 95% light interception improves the structure and nutritive value of tanzania grass pastures.

Abstract: the flow measurement of liquids and gases is a necessity in many industrial applications. there is a great amount of measurers for such purpose, as, for example, the coriolis, positive displacement and type turbine measurers. a measurer sufficiently used for the oil flow measurement is the turbine type, because it uses the proper extracted energy of the measured flow for its functioning, moreover is also used as standard for the calibration of other measurers. for this reason, it is important to study the parameters that influence the measurement process for turbine measurers. in brazil, to measure the volume of oil, regardless the type of measurer, it is necessary to observe "portaria conjunta no. 1", of june 19, 2000, that approved the technical regulation of measurement of oil and natural gas, establishing the minimum conditions and requirements for the systems of oil and natural gas measurement, in order to get a measurement standard. as such, the present work has the objective of determining parameters that influence in the measurement of oil volumes using turbine measurers.

Abstract: the objective of this work was to evaluate effects of nitrogen fertilization and plant density on morphogenesis of tanzania guinea grass. it was used a random block design with 12 treatments and two replications in a 4 × 3 factorial arrangement, with four doses of nitrogen (n) (without n application, 80, 160 or 320 kg/ha.year) and three plant densities (9, 25 or 49 plants/m2). harvest was performed at 25 cm from the ground when the canopy intercepted 95% of the incident light. rates of leaf appearance and pseudostem elongation were positively and linearly influenced by nitrogen, whereas phillochron and leaf life span were influenced linearly and negatively. leaf elongation responded positively to two factors, whereas leaf senescence rate and number of live leaves were not influenced by the factors evaluated. number of total, basal and aerial tillers were greater at the density of 9 plants/m2 and at the nitrogen dose of 320 kg/ha.year. nitrogen increases production of leaves and tillers in tanzania guinea grass defoliated at 95% of light interception, but high density of plants reduces the number of tiller per bunch.
Aids, Política e Sexualidade: refletindo sobre as respostas governamentais à Aids na áfrica do Sul e no Brasil
Santos, Gustavo Gomes da Costa;
Physis: Revista de Saúde Coletiva , 2009, DOI: 10.1590/S0103-73312009000200003
Abstract: this paper attempts to analyze the governmental responses to aids epidemic in two conflicting cases: brazil and south africa. drawing on the examination of aids epidemic's trajectories in both countries and the extensive literature about that thematic, we try to comprehend the reason for such diversified governmental responses to those similar sociopolitical contexts. the paper supports that the inter-relations between political institution and wider processes of nation-building can explain such different governmental responses to aids and illuminate the complex relationship between aids, sexuality, race and national identity in brazil and south africa.
