Josélia Braz dos Santos Ferreira, Selma Petra Chaves Sá, Rosimere Ferreira Santana, Ana Maria Domingos, Juliana Peres da Costa Pereira, Luciana Krauss Rezende
Open Journal of Therapy and Rehabilitation (OJTR) , 2016, DOI: 10.4236/ojtr.2016.42006
Abstract: This study analyzed postural balance in the elderly with mild cognitive impairment and its relationship to accidental falls. A quantitative and quasi-experimental method was used in a sample of 43 elderlies between 64 and 88 years old, mostly females. Data collection was performed in two Basic Health Units in the city of Rio de Janeiro in 2014. The instruments used were the Mini-Mental State Examination (MMSE), Tinetti scale, Motor Scale for the Elderly (EMTI) scale, and Elderly Falls Diary. The data were analyzed with the SAS statistical software version 9.3.1. The scales were applied before and after the psychomotor interventions. A significant difference was observed between the evaluating moments. Balance improvements were observed in all age groups, suggesting that all elderlies, regardless of age, showed satisfactory responses to the implemented psychomotor activities. The elderlies who fell more frequently were those between 60 and 69 years old. It is noteworthy that the age group with the lowest incidence of falls was that of elderlies between 70 and 79 years old. It was concluded that psychomotor activities are beneficial, regardless of age, proving their effectiveness when continued stimuli with cognitive and psychomotor activities are carried out.

Abstract: this article seeks to characterize the risks related to the use of pesticides in dairy production, in terms of legislation, health and perception of risk for workers involved in this activity. it is based on methodological articulation that included: a) systematic review of the reference literature on the research topic; b) analysis of related legislation (veterinary products and pesticides); c) risk identification regarding the use of veterinary products formulated using active ingredients listed as pesticides; d) and risk perception analysis of a group of dairy production workers. results indicate a situation of particular interest to public health. regarding dairy production workers, the invisibility of risks associated with handling pesticides for veterinary use, increases their exposure and is related to several health problems, especially for women. this same invisibility leads to a neglect of the prohibition period between pesticide use and consumption of other products. part of the problem may be associated with the non-classification of pesticides for veterinary use as 'pesticides' (they are classified as veterinary products), which highlights the importance and the urgency of discussion of the theme.

Abstract: The greater use of crop fields by increasing plant population is an alternative to minimize losses to the farmers who use crop intercropped provides other benefits such as lower incidence of diseases and pests, and better exploitation and enrichment agroecosystem. The objective of this study was to evaluate the effect of the population of peanuts with and without inoculation and intercropping with forage palm on growth, productivity and biomass peanut. The treatments consisted of different populations of peanut (one, two and three rows of peanut row spacing of two meters of cactus pear), with and without inoculant, analyzed in subdivided plot scheme (3 × 2), totalizing six treatments in a randomized block design with four replications. The variables evaluated were plant height, number of branches, shoot dry mass and root nodule number, nodule dry weight, biomass productivity and legumes. The largest population of plants in number of lines of peanut intercropped with forage cactus promotes greater total biomass production and yield of beans and does not alter the height, branch number, dry mass of aerial part roots and nodules. The inoculant application did not result in to increased productivity biomass and growth of peanut plants, their use is not indicated. The planting of a row of peanuts between the rows of palm is not economically recommended.

Abstract: The present work aimed to evaluate the effects of simulated drift of glyphoste on Eucalyptus grandis, through the application of low doses in different parts of the plant. The experimental design was a randomized block design with five replications. The treatments were glyphosate application at 0; 30; 60; 90 e 120 g a.e. ha-1 of the commercial formulation Scout . Three forms of application were used: applying on leaf, on stem, and on the entire plant (leaf + stem). For leaf application, stems were covered with plastic ribbons to protect them from the solution; the same was made with plants that were sprayed on stems, covering leaf with plastic bag. The application was carried out in an armed stationary spray tips XR 11002 VS, with 183 KPa pressure in volume of 200 L ha-1. The eucalyptus plants receiving applications in leaves and whole plant (leaves + stem) showing effects of intoxication are more intense about the plants that received the stem applications only. However, there may be increases in height growth and total dry mass of eucalyptus plants in applications of 30 g a.e. ha-1 glyphosate. No presente trabalho objetivou-se avaliar os efeitos da deriva simulada de glyphoste em plantas de Eucalyptus grandis, por meio da aplica o de doses reduzidas em diferentes partes da planta. Utilizouse o delineamento inteiramente casualizado, com cinco repeti es. Os tratamentos foram constituídos da aplica o de 0; 30; 60; 90 e 120 g e.a.ha-1 de glyphosate, da formula o comercial Scout . A aplica o foi realizada de três formas: aplica o sobre as folhas, no caule e na planta inteira (folha + caule). Para a aplica o nas folhas o caule foi coberto com fitas plásticas para evitar que fosse atingido pela solu o, e o mesmo foi feito com as plantas que receberam pulveriza o no caule, cobrindo as folhas com saco plástico. A aplica o foi realizada em um pulverizador estacionário, munido de pontas XR 11002 VS, com press o de 183 KPa e com consumo de calda de 200 L ha-1. As plantas de eucalipto que receberam aplica es nas folhas e na planta inteira (folhas + caule) apresentaram efeitos de intoxica o mais intenso em rela o às plantas que receberam aplica es somente no caule. Entretanto, pode ocorrer incrementos no crescimento em altura e na massa seca total das plantas de eucalipto em aplica es da dose de 30 g e.a. ha-1 de glyphosate.

Abstract: The objective of this study was to evaluate the effect of nozzles on spray droplet deposition in the peanut crop cultivar ‘Runner IAC 886’. The study was conducted in the field, and the applications of treatments performed in the vegetative stage (V1) and reproductive (R2). It was used the Brilliant Blue FDC – 1 as tracer in water solution, at 500 ppm. The treatments consisted of seven spray nozzle XR 110015 VS (150 L ha-1), XR 11002 VS (200 L ha-1), TX-VK 6 (150L ha-1), TX-VK 8 (200 L ha-1), AI 110015 VS (150 L ha-1), AI11002 VS (200 L ha-1) e TJ60 11002 VS (150 e 200 L ha-1). It was used a randomized blocks design, with four replications. After application, plants were immediately collected, and washed in 100 mL of distilled water for posterior tracer quantification in spectrophotometer. The data had been adjusted a regression curve for Gompertz model. The results had evidenced that at low volumes of application the nozzle AI 110015 VS and TJ60 11002 VS, were the ones with best distribution uniformity of spray on plants of peanut cultivar ‘Runner IAC 886’ in the vegetative stage (V1) and reproductive (R2) respectively, and the largest deposits and higher percentage of failures in applications have been found in younger plants by comparing the growth stages of application, regardless of the spray nozzle and volume. O objetivo deste estudo foi o de avaliar o efeito de pontas de pulveriza o na deposi o de gotas na cultura do amendoim da cultivar ‘Runner IAC 886’. O estudo foi realizado a campo, sendo as aplica es dos tratamentos realizadas nos estádios vegetativo (V1) e reprodutivo (R2). Foi utilizado como marcador o corante Azul Brilhante FDC -1 na concentra o de 500 ppm. Os tratamentos foram constituídos por sete pontas de pulveriza o: XR 110015 VS (150 L ha-1), XR 11002 VS (200 L ha-1), TX-VK 6 (150L ha-1), TX-VK 8 (200 L ha-1), AI 110015 VS (150 L ha-1), AI11002 VS (200 L ha-1) e TJ60 11002 VS (150 e 200 L ha-1). Utilizou-se o delineamento em blocos ao acaso, com 4 repeti es. Após a aplica o, as plantas foram imediatamente coletadas, e lavadas em 100 mL de água destilada para posterior quantifica o do marcador em espectrofot metro. Para as análises qualitativas, cada planta selecionada ao acaso dentro da faixa de aplica o da barra foi considerada uma repeti o, o que representou um total de 100 repeti es. Os dados obtidos foram ajustados à curva de regress o pelo modelo de Gompertz. Os resultados evidenciaram que independente do volume de aplica o as pontas AI 110015 VS e AI 11002 VS, foram as que proporcionaram maiores depósitos de calda
