The use of a task through virtual reality in cerebral palsy using two different interaction devices (concrete and abstract) - a cross-sectional randomized study.

BACKGROUND: Cerebral Palsy (CP) is characterised by variable difficulties in muscular action, resulting in inability of the individual to perform functional movement. An option to provide functionality to the individual with CP is the use of computer innovation. The aim of this paper was to verify if there was any performance improvement in a task performed in a virtual environment and if there was transfer to the task performed in the real environment and vice versa in this population. METHODS: A computer program was developed comprising a motor task, but with two possibilities of user interaction: a) concrete interface (with physical contact): in which the individual touches the computer screen to finish the task and b) abstract interface (no physical contact): in which the individual performs a hand movement in front of the Kinect device. Participants were split into two groups. The experimental group consisted of 28 individuals with CP within the ages of 6 and 15 years old. The control group included 28 typically developing individuals mirroring the age and sex of the experimental group. RESULTS: Individuals from both groups were able to improve task performance and retain acquired information. The CP group presented worse performance than the control group in all phases of the study. Further findings showed that the CP group presented better performance in the abstract interface than in the concrete interface, whereas, in the control group, the opposite occurred: their best performance was in the concrete. CONCLUSIONS: Motor tasks performed by individuals with CP through an interface with a more virtual environment feature (abstract interface: Kinect) provided better performance when compared to an interface with a more real characteristic (concrete interface: Touchscreen).

Controle alternativo de podridões pós‑colheita de framboesas

O objetivo deste trabalho foi avaliar o efeito de tratamentos pré-colheita sobre a ocorrência de podridões pós-colheita e sobre os atributos de qualidade de framboesas (Rubus idaeus L.) 'Heritage'. As frutas foram pulverizadas com um dos seguintes tratamentos: água destilada (controle), 6 g L-1 de quitosana, 100 mg L-1 de dióxido de cloro, Bacillus amyloliquefaciens, Curtobacterium pusillum ou Saccharomyces cerevisiae. Foram realizadas colheitas aos 3, 7 e 14 dias após a aplicação dos tratamentos. Após cada uma das colheitas, realizadas no estádio de maturação comercial (coloração rosa), as frutas foram inoculadas individualmente com suspensão de conídios (2x10(5) conídios mL-1) de Botrytis cinerea ou Rhizopus stolonifer. As frutas foram mantidas a 12±0,5ºC por sete dias e avaliadas quanto à incidência de podridões e quanto aos principais atributos de qualidade. Bacillus amyloliquefaciens, C. pusillum e S. cerevisiae proporcionaram menor área abaixo da curva de progresso da incidência das podridões por Botrytis e Rhizopus. Os agentes de controle biológico avaliados não interferem negativamente sobre os atributos de qualidade das frutas, e, portanto, são alternativas potenciais no controle de podridões pós-colheita de framboesas

Search for long-lived neutral particles in pp collisions at s√=13 TeV that decay into displaced hadronic jets in the ATLAS calorimeter

This paper describes a search for pairs of neutral, long-lived particles decaying in the ATLAS calorimeter. Long-lived particles occur in many extensions to the Standard Model and may elude searches for new promptly decaying particles. The analysis considers neutral, long-lived scalars with masses between 5 and 400 GeV, produced from decays of heavy bosons with masses between 125 and 1000 GeV, where the long-lived scalars decay into Standard Model fermions. The analysis uses either 10.8 fb−1 or 33.0 fb−1 of data (depending on the trigger) recorded in 2016 at the LHC with the ATLAS detector in proton–proton collisions at a centre-of-mass energy of 13 TeV. No significant excess is observed, and limits are reported on the production cross section times branching ratio as a function of the proper decay length of the long-lived particles

Composition And Molluscicidal Properties Of Essential Oils From Leaves Of Xylopia Langsdorffiana A. St. Hil. Et Tul. (annonaceae)

The volatile fraction of Xylopia langsdorffiana leaves was analyzed by GC and GC/MS and tested for molluscicidal activity. With this methodology 19 different components were identified in the oil. Among them, germacrene D (22.9%), trans-β-guaiene (22.6%), β-caryophyllene (15.7%), and α-pinene (7.3%) were found to be the major constituents. The oil showed significant molluscicidal activity against Biomphalaria glabrata, with an LC90 value of 5.6 μ.g/mL, which falls below the threshold of 100 μg/mL, set for potential molluscicidal activity by the World Health Organization. © 2007 Allured Publishing Corp.193282284Lardans, V., Dissous, C., Snail control strategies for reduction of schistosomiasis transmission (1998) Parasitol.
