Multivariate analysis of walker-assisted ambulation

In an aging society it is extremely important to develop devices which can support and aid the elderly in their daily life. Walkers play an important role, due to the large number of potential users, its simplicity and their ambulatory potential. However, there are no clinical evidences that prove the efficacy of such devices, mainly rollators that present forearm supports. In this context, the authors aim to propose a protocol for an innovative gait analysis that addresses some benefits and limitations of these devices on the rehabilitation process, by addressing a multivariate analysis of spatiotemporal and kinematic gait parameters assessed during normal and assisted ambulation with a walker with forearm supports. For the 3Dreconstruction of the body segments it was used a movement analysis system. Results showed that the effects of assisted gait can be explained through support, energy consumption, posture and balance characteristics. These results are very satisfactory since aspects regarding these characteristics enhance the rehabilitation potential of the use of walkers with forearm supports. These results will be used to advance towards an active robotic walker that will provide for safety and natural manoeuvrability and offer a certain degree of intelligence in assistance and decision-making

Biodegradation of diethylketone by two fungi

Two morphologically different fungi (one green and one white) from contaminated bioreactors with an aqueous solution of diethylketone and Streptococcus equisimilis were isolated and characterized at molecular level by sequencing the amplified ITS region. The ITS region sequence showed 99% match with Alternaria genera for the green fungi and 99% match with the Penicillium genera for the white fungi. The performance of these two fungi to biodegrade different concentrations of diethylketone from aqueous solutions was evaluated. The biodegradation of diethylketone was studied for an initial diethylketone concentration ranging from 0.5 to 4g/L in a batch mode of operation. The biodegradation rate found for both fungi followed the pseudo-second order kinetics for initial concentrations higher than 0.5 g/L and the resulting kinetic parameters are reported. The removal percentages obtained were approximately 100%, for all the initial concentrations tested

Avanços da agricultura familiar em latossolo vermelho - amarelo distrófico no Estado de Rondônia, Amazônia brasileira - Levantamento Preliminar.

O presente artigo é um estudo preliminar de uma pesquisa envolvendo agricultores que utilizam sistemas de cultivo agroecológico no Município de Alto Paraíso-Rondônia localizado na Amazônia Brasileira. O objetivo do artigo é identificar a classe de solo dos agricultores envolvidos com agroecologia e correlacionar com dados de aptidão agrícola do Planafloro - Plano Agroflorestal de Rondônia, visando subsidiar políticas públicas e ambientais. O solo classificado como Latossolo Vermelho Amarelo Distrófico é o de maior ocorrência no Município sendo sua fertilidade natural baixa a muito baixa, e constituindo assim a principal limitação de uso agrícola. Apesar disso, agricultores agroecológicos tem conseguido desenvolver cultivos neste tipo de solo
