Household survey of hepatitis B vaccine coverage among Brazilian children

We conducted a multi-stage household cluster survey to calculate hepatitis B vaccine coverage among children 18-30 months of age in 27 Brazilian cities. Hepatitis B vaccine is administered at birth, 1 month and 6 months of age by Brazil`s national immunization program. Among 17,749 children surveyed, 40.2% received a birth dose within one day of birth, 94.8% received at least one dose of hepatitis B vaccine, and 86.7% completed the three-dose series by 12 months of age. Increased coverage with the birth dose and administration of hepatitis B in combination with diphtheria-tetanus-pertussis-Haemophilus influenzae type b antigens could improve protection against hepatitis B.

The C(K, X) spaces for compact metric spaces K and X with a uniformly convex maximal factor

In this paper, we prove that if a Banach space X contains some uniformly convex subspace in certain geometric position, then the C(K, X) spaces of all X-valued continuous functions defined on the compact metric spaces K have exactly the same isomorphism classes that the C(K) spaces. This provides a vector-valued extension of classical results of Bessaga and Pelczynski (1960) [2] and Milutin (1966) [13] on the isomorphic classification of the separable C(K) spaces. As a consequence, we show that if 1 < p < q < infinity then for every infinite countable compact metric spaces K(1), K(2), K(3) and K(4) are equivalent: (a) C(K(1), l(p)) circle plus C(K(2), l(q)) is isomorphic to C(K(3), l(p)) circle plus (K(4), l(q)). (b) C(K(1)) is isomorphic to C(K(3)) and C(K(2)) is isomorphic to C(K(4)). (C) 2011 Elsevier Inc. All rights reserved.

Padrões nutricionais para lavouras arrozeiras irrigadas por inundação pelos métodos da CDN chance matemática

Para o arroz irrigado, poucos trabalhos utilizam métodos de diagnose foliar desenvolvidos para as condições locais de clima, solo ou cultivares. O objetivo deste trabalho foi avaliar os métodos da Diagnose da Composição Nutricional e da Chance Matemática na definição dos padrões nutricionais de lavouras arrozeiras do Estado do Rio Grande do Sul. Resultados de produtividade de grãos e teores foliares de N, P, K, Ca, Mg, S, B, Cu, Fe, Mn, Zn e Mo de 356 lavouras arrozeiras cultivadas sob sistema de irrigação por inundação foram utilizados para a determinação das faixas de suficiência calculadas pelo método da Chance Matemática. As faixas de suficiência foram comparadas com valores críticos propostos pela literatura e com o intervalo de confiança do teor médio dos nutrientes em lavouras consideradas nutricionalmente equilibradas, identificadas pelo método Diagnose da Composição Nutricional. Observou-se pouca concordância entre os valores das faixas de suficiência indicados pelos métodos da Chance Matemática e da Diagnose da Composição Nutricional e os respectivos valores indicados na literatura. A faixa de teores foliares adequados, consistentes com maior produtividade média das lavouras arrozeiras, foi indicada ser de 23 a 28 g kg-1 para N; 11 a 14 g kg-1 para K; 1,4 a 2,0 g kg-1 para S; 6 a 12 mg kg-1 para B; e 70 a 200 mg kg-1 para Fe. Para os teores foliares de P, Ca, Mg, B, Cu, Mn e Zn e Mo nenhuma das faixas adequadas testadas indicou capacidade para distinguir as lavouras arrozeiras quanto à produtividade média.

Efeito de doses e tipos de compostos orgânicos na produção de alface em dois solos sob ambiente protegido

Avaliou-se o efeito de três doses de composto orgânico de três composições distintas, aplicados em dois solos [Latossolo Vermelho Escuro, textura arenosa (LE) e Areia Quartzoza (AQ)], na produção e absorção de nutrientes pela planta de alface. Conduziu-se de 02/07 a 27/08/1997 um experimento dentro de túnel plástico, pertencente à UNESP, em Botucatu, em vaso plástico, contendo quatro quilos de solo. Os solos foram corrigidos para atingirem saturação por base de 80% e todos os vasos receberam adubação fosfatada (150 mg de P kg-1 de solo), potássica (100 mg de K kg-1 de solo) e micronutrientes. Os compostos foram misturados aos solos nas quantidades de 60; 120 e 240 g de composto por vaso. Os três compostos foram originados a partir de casca de eucalipto, serragem de madeira e palhada de feijão, misturados com esterco de aves. O experimento foi realizado em delineamento inteiramente casualizado, em três repetições, com vinte tratamentos em esquema fatorial (3 doses x 3 compostos x 2 solos) mais um tratamento testemunha para cada solo (ausência de composto orgânico). O composto de palhada de feijão aumentou a biomassa fresca da parte aérea e a quantidade de N, K, Ca, Mg, B, Cu, Fe e Zn nas plantas de alface. Para o P e Mn o composto de palhada de feijão diferiu significativamente apenas em relação ao composto de casca de eucalipto. em todas as características avaliadas no LE houve melhores respostas da cultura em relação ao AQ. Quanto às dosagens utilizadas, as diferenças foram observadas somente nos tratamentos com palhada de feijão, onde as maiores dosagens propiciaram o aumento de biomassa fresca e seca da parte aérea, e nas quantidades de macro e micronutrientes.

Níveis crescentes de saturação por bases e desenvolvimento inicial de teca em um latossolo de textura média

Teak is a forest species of high commercial value, but the little knowledge on the behavior of this species in relation to soil acidity is an important factor that may limit its cultivation. The aim of this study was to evaluate the effect of high base saturation on the soil on the initial development of teak (Tectona grandis L.f.). The experiment was conducted in a greenhouse, in plastic containers with capacity of 50 liters. The experimental design was randomized, with five treatments and four replications. The treatments consisted of: natural saturation of the soil and the other treatments with 20 %, 40 %, 60 % and 80 % of saturation. Correcting the soil favored the growth characteristics of all evaluated plant teak. The liming positively affected the uptake of N, P, K, Ca, Mg, B, Cu and Fe, and the nutritional requirements of the species had the following order: N > Ca > K > Mg > P > S > Fe > Mn > B > Zn > Cu. Base saturations above 70 % showed higher plant development.

Fontes e doses de manganês no acúmulo de nutrientes na palhada em cana-de-açúcar

The sugar cane crop uptake high amount of nutrients from the soil and the lack of these elements can result in low productivity of this crop. This study aimed to evaluate the effect of sources and doses of manganese on the accumulation of macro-and micronutrients of straw and stalk yield in the sugar cane crop. The experiment was conducted at Fujimoto farm, area administered by the Vale do Parana SA Alcohol and Sugar located in Suzanapolis - SP county. The experimental design was randomized blocks in a factorial scheme 5x3, with five levels of manganese and three sources, applied at planting, in four replications. The plots consisted of four rows 5 m long, spaced by 1.5 m. The variety used was RB 86-7515. The variables analyzed in the sugar cane plant and sugar cane ratoon cane were: accumulation of macro-and micronutrients, dry weight of straw and crop yield. The sources Mn influenced the accumulation of N, P and K in the straw cane plant and ratoon sugar cane in the accumulation of K, Ca, S, B, Mn and Zn. The increasing levels of Mn increased the cumulative amount of Ca, Mg, S and Mn in the cane plant and stubble of Ca, Fe and Mn in sugar cane ratoon. The sources of Mn did not influence the dry matter yields of straw and stalk, so as to plant cane to first sugar cane ratoon. The levels of Mn influenced linearly the dry straw on cane plant. As for the stem yield of sugarcane plant and sugar cane ratoon was not influenced by the levels of Mn.

Search for B-s(0)->mu(+)mu(-) decays at D0

We report results from a search for the decay B-s(0)->mu(+)mu(-) using 1.3 fb(-1) of p (p) over bar collisions at root s = 1.96 TeV collected by the D0 experiment at the Fermilab Tevatron Collider. We find two candidate events, consistent with the expected background of 1.24 +/- 0.99, and set an upper limit on the branching fraction of B(B-s(0)->mu(+)mu(-))< 1.2x10(-7) at the 95% C.L.

Properties of l=1 B-1 and B*(2) Mesons

This Letter presents the first strong evidence for the resolution of the excited B mesons B-1 and B-2(*) as two separate states in fully reconstructed decays to B+(*())pi(-). The mass of B-1 is measured to be 5720.6 +/- 2.4 +/- 1.4 MeV/c(2) and the mass difference Delta M between B-2* and B-1 is 26.2 +/- 3.1 +/- 0: 9 MeV/c(2), giving the mass of the B-2* as 5746.8 +/- 2.4 +/- 1.7 MeV/c(2). The production rate for B-1 and B-2* mesons is determined to be a fraction (13.9 +/- 1.9 +/- 3.2)% of the production rate of the B+ meson.

Measurement of B-d mixing using opposite-side flavor tagging

We report on a measurement of the B-d(0) mixing frequency and the calibration of an opposite-side flavor tagger in the D0 experiment. Various properties associated with the b quark on the opposite side of the reconstructed B meson are combined using a likelihood-ratio method into a single variable with enhanced tagging power. Its performance is tested with data, using a large sample of reconstructed semileptonic B ->mu(DX)-X-0 and B ->mu(DX)-X-* decays, corresponding to an integrated luminosity of approximately 1 fb(-1). The events are divided into groups depending on the value of the combined tagging variable, and an independent analysis is performed in each group. Combining the results of these analyses, the overall effective tagging power is found to be epsilon D-2=(2.48 +/- 0.21(-0.06)(+0.08))%. The measured B-d(0) mixing frequency Delta m(d)=0.506 +/- 0.020(stat)+/- 0.016(syst) ps(-1) is in good agreement with the world average value.

Measurement of the t(t)over-bar production cross section in p(p)over-bar collisions at root s=1.96 TeV using secondary vertex b tagging

We report a new measurement of the t (t) over bar production cross section in p (beta) over bar collisions at a center-of-mass energy of 1.96 TeV using events with one charged lepton (electron or muon), missing transverse energy, and jets. Using 425 pb(-1) of data collected using the D0 detector at the Fermilab Tevatron Collider, and enhancing the t (t) over bar content of the sample by tagging b jets with a secondary vertex tagging algorithm, the t (t) over bar production cross section is measured to be sigma(p (t) over bar -> t (t) over bar +X)=6.6 +/- 0.9(stat+syst) +/- 0.4(lum) pb. This cross section is the most precise D0 measurement to date for t (t) over bar production and is in good agreement with standard model expectations.

Search for the rare decay B-s(0)->phi mu(+)mu(-) with the D0 detector

We present a search for the flavor-changing neutral current decay B-s(0)->phi mu(+)mu(-) using about 0.45 fb(-1) of data collected in p (p) over bar collisions at root s=1.96 TeV with the D0 detector at the Fermilab Tevatron Collider. We find an upper limit on the branching ratio of this decay normalized to B-s(0)-> J/psi phi of B(B-s(0)->phi mu(+)mu(-))/B(B-s(0)-> J/psi phi)< 4.4x10(-3) at the 95% C.L. Using the central value of the world average branching fraction of B-s(0)-> J/psi phi, the limit corresponds to B(B-s(0)->phi mu(+)mu(-))< 4.1x10(-6) at the 95% C.L., the most stringent upper bound to date.

Measurement of the B-s(0) lifetime using semileptonic decays

We report a measurement of the B-s(0) lifetime in the semileptonic decay channel B-s(0)-> D-s(-)mu(+)nu X (and its charge conjugate), using approximately 0.4 fb(-1) of data collected with the D0 detector during 2002-2004. Using 5176 reconstructed D-s(-)mu(+) signal events, we have measured the B-s(0) lifetime to be tau(B-s(0))=1.398 +/- 0.044(stat)(-0.025)(+0.028)(syst) ps. This is the most precise measurement of the B-s(0) lifetime to date.
