Objective. This study aimed to investigate the effect of virtual therapy on the motor ability of hemiparetic children's upper limb. Method. The sample consisted of three hemiparetic children (8.66±2.30 years). The Pediatric Evaluation of Disability of Inventory (PEDI) and Motor Activity Inventory (MAL) were used for initial and final assessments and the number of hits in each game was counted as well. For the treatment, a hardware (video game) was used, Nintendo brand, model Wii Sports software, using the games (tennis, baseball, golf, boxing). During a period of two weeks, the therapy lasted for 1 hour and 10 minutes each day, consecutively. Results. There was statistical difference in two children in the PEDI (p=0,00) and in the MAL, related to the quality of the upper limb's use (p=0,00) where as relation to the frequency of use, there was statistical difference in all three children in all four games had a increase. Conclusion. It was concluded that the use of Virtual Reality can promote functional gain for hemiparetic children's upper limb.214556562Costa, M.C.F., Bezerra, P.P., Oliveira, A.P.R., Impacto da hemiparesia na simetria e na transferência de peso: Repercussões no desempenho funcional (2006) Rev Neurocienc, 14, pp. 10-13Ortega, D.S., O Paciente Neurológico/Neurocirúrgico Pediátrico (2007) Fisioterapia Respiratória Em Pediatria E Neonatologia, pp. 176-195. , Sarmento GJV., Barueri: ManoleGomes, F.L., Fraqueza Muscular (2007) Guias De Medicina, pp. 1857-1871. , Lopes AC, José FF, Lopes Rd., Barueri: ManoleMorais, G.F.S., Nascimento, L.R., Glória, A.E., Salmela, L.F.T., Paiva, C.M.R., Lopes, T.A.T., A influência do fortalecimento muscular no desempenho motor do membro superior parético de indivíduos acometidos por Acidente Vascular Encefálico (2008) Acta Fisiatr, 15, pp. 245-248Nascimento, L.R., Glória, A.E., Habib, E.S., Effects of constraint-induced movement therapy as a rehabilitation strategy for the affected upper limb of children with hemiparesis: Systematic review of the literature (2009) Rev Bras Fisioter, 13, pp. 97-102. , http://dx.doi.org/10.1590/S1413-35552009005000022Gianni, M.A.D.C., Paralisia Cerebral - Aspectos clínicos (2005) Fisioterapia: Aspectos Clínicos E Práticos Da Reabilitação, pp. 13-25. , Moura EW, Silva PAC., 3 ed.

Balanços energéticos agropecuários: uma importante ferramenta como indicativo de sustentabilidade de agroecossistemas.

No Brasil, pouca atenção se tem dado às formas e caminhos com que os fluxos energéticos se distribuem nos sistemas produtivos. Na agropecuária, a atenção tem sido voltada a novas fontes de energia (biomassa) ou em tecnologia alternativa, visando a racionalização do uso de energia fóssil ou elétrica. Entretanto, a agricultura tem se desenvolvido baseada fortemente na utilização intensiva de máquinas agrícolas, com conseqüente uso de combustíveis fósseis. Um fator de estrangulamento muito forte no consumo energético geral tem sido a utilização massiva de fertilizantes derivados do petróleo nos agroecossistemas. Estudos de Balanços Energéticos visam determinar os pontos de estrangulamento energético fundamentando a busca por tecnologias poupadoras de energia, especialmente aquelas de origem fóssil (combustível, fertilizante, agrotóxicos, energia despendida na fabricação das máquinas e implementos, etc.). No Brasil, a Região Sul, é onde se encontram vários trabalhos buscando uma agricultura mais auto-sustentável, do ponto de vista da utilização da energia. Em vista da possibilidade de eventuais futuras crises energéticas, o presente trabalho procura analisar o estado-da-arte dos estudos em Balanço Energético, no Brasil e no Mundo, como uma ferramenta de indicação da sustentabilidade dos sistemas agropecuários

Development of a qPCR for Leifsonia xyli subsp. xyli and quantification of the effects of heat treatment of sugarcane cuttings on Lxx

The main control practice of Leifsonia xyli subsp. xyli (Lxx) in sugarcane is to heat-treat cane cuttings used as planting material in an attempt to eradicate the bacterium. A real time quantitative PCR (qPCR) protocol specific for Lxx was developed to assess the effectiveness of this practice. Primers were designed from the sequence of an Lxx-specific gene and detected as few as 10−5 ng of Lxx DNA in 100 ng of plant DNA. Two experiments were conducted to quantify Lxx titers in plants of the varieties SP80-3280 and SP70-3370 originated from cuttings treated or not by immersion in hot water at 52 °C for 30 min. In the first experiment, cuttings were collected from plant canes with low Lxx titers whereas in the second they were collected from first-ratoon canes with higher titers. Lxx was quantified in leaves by qPCR 90 days after planting and was detected in 50–90% of the plants at variable titers, indicating that the 52 °C hot water treatment for 30 min was not effective in eradicating Lxx from all plants. However, in the second experiment the bacterial population was reduced, as the median number of Lxx cells was lower compared to the non-treated control. In the case of SP70-3370, the treatment also reduced the number of Lxx-infected plants considering the pooled data of the two experiments. The results indicated that although the 52 °C hot water treatment for 30 min did not completely eliminate Lxx, it can be used to reduce the pathogen population in plants propagated from canes with high Lxx titer

Oviposição do curuquerê e alimentação de suas lagartas neonatas em algodoeiros tratados com caulim

Resumo: O objetivo deste trabalho foi avaliar a capacidade do caulim de afetar a oviposição e a alimentação de Alabama argillacea (Lepidoptera: Noctuidae) em algodoeiro. Determinou-se a preferência de oviposição, a viabilidade de ovos e o consumo das lagartas de primeiro instar de A. argillacea, em folhas de algodão tratadas ou não com caulim. A preferência de oviposição foi determinada por teste de escolha e confinamento, em delineamento experimental de blocos ao acaso, em arranjo fatorial 2x7, representado pelos tratamentos com caulim em água destilada (60 g L-1) ou somente água destilada (testemunha), e pela avaliação de sete estruturas vegetais da planta. O consumo pelas lagartas de primeiro instar foi determinado em delineamento experimental inteiramente casualizado, em arranjo fatorial 2x4, representado pelo tratamento com caulim em água destilada, pela testemunha e pelos quatro períodos de observação (6, 12, 24 e 48 horas). A oviposição das mariposas do curuquerê-do-algodoeiro foi reduzida nas plantas de algodão tratadas com caulim; no entanto, a viabilidade dos ovos não foi afetada. A folha da haste foi a estrutura preferida para oviposição. A sobrevivência e o consumo de lagartas de primeiro instar do curuquerê são menores nas plantas de algodão tratadas com caulim

Search for a W' boson decaying to a bottom quark and a top quark in pp collisions at sqrt(s) = 7 TeV

Results are presented from a search for a W' boson using a dataset corresponding to 5.0 inverse femtobarns of integrated luminosity collected during 2011 by the CMS experiment at the LHC in pp collisions at sqrt(s)=7 TeV. The W' boson is modeled as a heavy W boson, but different scenarios for the couplings to fermions are considered, involving both left-handed and right-handed chiral projections of the fermions, as well as an arbitrary mixture of the two. The search is performed in the decay channel W' to t b, leading to a final state signature with a single lepton (e, mu), missing transverse energy, and jets, at least one of which is tagged as a b-jet. A W' boson that couples to fermions with the same coupling constant as the W, but to the right-handed rather than left-handed chiral projections, is excluded for masses below 1.85 TeV at the 95% confidence level. For the first time using LHC data, constraints on the W' gauge coupling for a set of left- and right-handed coupling combinations have been placed. These results represent a significant improvement over previously published limits.Comment: Submitted to Physics Letters B. Replaced with version publishe

Measurement of the polarisation of W bosons produced with large transverse momentum in pp collisions at sqrt(s) = 7 TeV with the ATLAS experiment

This paper describes an analysis of the angular distribution of W->enu and W->munu decays, using data from pp collisions at sqrt(s) = 7 TeV recorded with the ATLAS detector at the LHC in 2010, corresponding to an integrated luminosity of about 35 pb^-1. Using the decay lepton transverse momentum and the missing transverse energy, the W decay angular distribution projected onto the transverse plane is obtained and analysed in terms of helicity fractions f0, fL and fR over two ranges of W transverse momentum (ptw): 35 < ptw < 50 GeV and ptw > 50 GeV. Good agreement is found with theoretical predictions. For ptw > 50 GeV, the values of f0 and fL-fR, averaged over charge and lepton flavour, are measured to be : f0 = 0.127 +/- 0.030 +/- 0.108 and fL-fR = 0.252 +/- 0.017 +/- 0.030, where the first uncertainties are statistical, and the second include all systematic effects.Comment: 19 pages plus author list (34 pages total), 9 figures, 11 tables, revised author list, matches European Journal of Physics C versio

Observation of a new chi_b state in radiative transitions to Upsilon(1S) and Upsilon(2S) at ATLAS

The chi_b(nP) quarkonium states are produced in proton-proton collisions at the Large Hadron Collider (LHC) at sqrt(s) = 7 TeV and recorded by the ATLAS detector. Using a data sample corresponding to an integrated luminosity of 4.4 fb^-1, these states are reconstructed through their radiative decays to Upsilon(1S,2S) with Upsilon->mu+mu-. In addition to the mass peaks corresponding to the decay modes chi_b(1P,2P)->Upsilon(1S)gamma, a new structure centered at a mass of 10.530+/-0.005 (stat.)+/-0.009 (syst.) GeV is also observed, in both the Upsilon(1S)gamma and Upsilon(2S)gamma decay modes. This is interpreted as the chi_b(3P) system.Comment: 5 pages plus author list (18 pages total), 2 figures, 1 table, corrected author list, matches final version in Physical Review Letter
