Abstract: this paper discusses the importance of mineral characterization as a support to understand their behavior in mineral processing and in the control of the processes and quality of the products obtained. also presented is a brief review on the main techniques used in minerals characterization, including the procedures for minerals separation from an ore. special attention was given to the technique of mineral separation from an ore according to their specific gravities using a device called magstream-model 100. it is shown that the magstream process, which involves the use of a magnetic fluid as a medium for mineral separation, a magnetic field and a rotation speed system, offers advantages compared to the heavy liquids technique. however, the magstream process leads to changes on mineral surface properties, imparting to them different flotation behaviors. this fact is considered a limitation for its use when further studies with the minerals involve surface properties.

Abstract: O presente trabalho discute a importancia da caracteriza o de minérios como suporte para o entendimento do comportamento de seus minerais frente a processos de tratamento de minérios, controle de processos e controle da qualidade dos produtos obtidos. é, também, apresentada uma breve revis o da literatura sobre as principais técnicas de caracteriza o, incluindo aquelas utilizadas para a separa o de minerais de um minério. Especial aten o foi dada à técnica de separa o de minerais de um minério, utilizando um equipamento chamado Magstream-Model 100. O trabalho mostra que o processo Magstream, que envolve o uso de fluido magnético como meio separador, campo magnético e um sistema de rota o, oferece vantagens em rela o a outras técnicas, como, por exemplo, a de líquidos densos. Entretanto o processo utilizado pelo Magstream leva a mudan as em propriedades de superfície dos minerais, modificando seus comportamentos frente à flota o. Esse fato foi considerado como uma limita o de seu uso, quando estudos posteriores com os minerais processados no Magstream envolvem propriedades de superfície.

Abstract: the covering of the soil is an agricultural practice that intends to control the harmful herbs, to reduce the losses of water by evaporation of the soil, and to facilitate the harvest and the commercialization, once the product is cleaner and healthier. however, when the soil is covered important microclimatic parameters are also altered, and consequently the germination of seeds, the growth of roots, the absorption of water and nutrients, the metabolic activity of the plants and the carbohydrates storage. the current trial intended to evaluate the effect of soil covering with blue colored film on consumptive water-use in a lettuce crop (lactuca sativa, l.). the experiment was carried out in a plastic greenhouse in araras - s?o paulo state, brazil from march 3rd, 2001 to may 5th, 2001. the consumptive water-use was measured through two weighing lysimeter installed inside the greenhouse. crop spacing was 0.25 m x 0.25 m and the color of the film above soil was blue. leaf area index (iaf), was measured six times (7; 14; 21; 28; 35; 40 days after transplant) and the water-use efficiency (eu) was measured at the end. the experimental design was subdivided portions with two treatments, "bare soil" and "covered soil". the average consumptive water-use was 4.17 mm day-1 to the "bare soil" treatment and 3.11 mm day-1 to the "covered soil" treatment. the final leaf area index was 25.23 to the "bare soil" treatment and 24.39 to the "covered soil" treatment, and there was no statistical difference between then.

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: the object of this study was to identify context elements that have an influence on pesticide use, related perceptions, and actions in flower production. the study was carried out in barbacena, minas gerais state. the method used was based on an anthropological fast diagnosis approach inspired on the signs, meanings and actions model and on the analysis of semi-structured interviews with 20 workers from four different flower-growing fields. the field data analysis indicates that these workers face two realities: the need for pesticides and suffering generated by pesticide management. furthermore, there is clearly no direct relation between risk awareness and the effective hazards associated with pesticides. this gap is filled by beliefs which are at the basis of their actions. these beliefs reinterpret information and risk, influence behavior, and make it possible for these workers to move between these two paradoxical realities and pesticide. attributing new meanings to pesticide management risks, however, may imply in positively valuing potentially harmful behaviors.

Abstract: This work had the purpose to evaluate the quality of the minimally processed snap bean in function of rinse and sanification operations. Snap bean cv. Itatiba 2 were selected, cleaned, processed and submitted to the following treatments: T1 – rinse in water only, T2 – rinse in water, followed by immersion in chlorinated solution (100 mg.L-1) for 5 minutes, T3 – immersion in chlorinated solution (100 mg.L-1) for 5 minutes and T4 – without rinse and without immersion in chlorinated solution (control). The minimally processed snap beans were assessed for appearance, color of the section surface and microbiological characteristics. About the color of the section surface, it could be noticed from the ninth day of storage that the snap bean of the Treatment 1 showed less darkening in relation to the other treatments, and also better accepted sensorially. It wasn’t detected Salmonella and neither coliforms at 45°C in any sample of the different treatments. In relation to the total coliform counts, it could be noticed reduction with the sanification (T2 and T3) on the processing day, and, in general, an increase in the coliform counts during the storage. The total bacteria count was > 105 UFC.g-1 in the snap bean of all treatments in the sixth day of storage, except in that one, which the snap beans were rinsed and sanitized. Therefore, this treatment is recommended and guarantee six days of shelf life for minimally processed snap bean, limited by the bacteria growth. Este trabalho teve como objetivo avaliar a qualidade de vagens minimamente processadas em fun o das opera es de enxague e sanifica o. Vagens cv. Itatiba 2 foram selecionadas, higienizadas, processadas e submetidas aos seguintes tratamentos: T1 - enxágue somente em água, T2 - enxágue em água, seguido de imers o em solu o clorada (100 mg.L-1) por 5 minutos, T3 - imers o em solu o clorada (100 mg.L-1) por 5 minutos e T4 - sem enxágue e sem imers o em solu o clorada (controle). As vagens minimamente processadas foram avaliadas quanto à aparência, colora o da superfície de corte e aspectos microbiológicos. Em rela o à colora o da superfície de corte, observou-se a partir do nono dia de armazenamento que as vagens do Tratamento 1 apresentaram menor escurecimento em rela o às dos demais tratamentos, sendo também melhor aceitas sensorialmente. Salmonella e coliformes a 45oC n o foram detectados em nenhuma amostra dos diferentes tratamentos. Em rela o à contagem de coliformes totais observou-se no dia do processamento redu o com a sanifica o (T2 e T3) e em geral, aumento dos coliformes durante
