Objective: To identify the perception of undergraduate dental students with respect of the risk factors present at the study/work place that could contribute to the development of musculoskeletal disorders. Method: A total of 348 undergraduate dental students from Araraquara Dental School - UNESP were evaluated. The Portuguese version of the Work-related activities that may contribute to job-related pain and/or injury questionnaire was used. Data were analyzed by descriptive statistics. Results: The mean perception of the undergraduates was 5.68 (SD=1.92). The factors with highest mean values were continue working with some kind of pain or lesion (7.49, SD=2.55), bending or twisting the back in an uncomfortable manner (7.39, SD=2.59), working in uncomfortable/inadequate positions (7.27. SD=2.60) and working in the same position for long periods (7.02. SD=2.53). Overall, female students presented higher mean scores of perception than male students. The body parts with highest prevalence of pain were the neck (67.0%) and lower back (65.8%). Conclusion: The students showed perception in relation to the risk factors for musculoskeletal disorders present at the study/work place.

Xanthan is a important biopolymer for commercial purpose and it is produced in two stages by Xanthomonas campestris. In the first one, the bacterium is cultivated in the complex medium enriched in nitrogen and the biomass produced is used as inoculum for the next stage in which the gum is produced in another medium. In this work a new medium for the first stage is proposed in place of currently used YM medium. Different formulated growth media were studied and the correspondent biomass produced was analysed as inoculum for the second stage. The inoculum and gum were produced by batch process in shaker at 27A degrees C in pH 6.0 and at 30A degrees C in pH 7.0, respectively. The gum was precipitated with ethanol (3:1 v/v). The dryed biomass and xathan gum produced were determined by drying in oven at 105 and 40A degrees C, respectively. The viscosity of the fermentation broth and 1% gum solution in water were determined in Brookfield viscometer. The formulated medium presented the increase in gum production (30%), broth (136%) and 1% gum solution viscosity (60%) compared to YM, besides the inferior cost. The results showed the importance of the quality of the inoculum from the first stage of the culture which influenced on the gum viscosity in the second stage.

Researchers and other professionals unanimously agree that companies should become more sustainable, but this will not happen without the support of human resource management. Paradoxically, there is a lack of information on the support human resource management offers to organizational sustainability applied to real cases. Therefore, this research presents a case study on this topic that was carried out in a leading Brazilian company, which is considered as a model and has been selected as 'the best place to work in the country'. The results provide practical examples of how this family company has been working to guarantee an increasingly sustainable performance with the support of human resources, highlighting the achievements and challenges the company has faced. One of the main results indicates that companies seeking to achieve sustainability need the assistance of the human resource field in order to design a communication system which bridges the gap between practices and sustainable values. © 2012 Management Centre for Human Values.

O objetivo deste trabalho foi avaliar a influência da operação da escarificação ao longo do tempo sobre a estrutura de um solo em plantio direto, assim como os seus efeitos sobre a produtividade do milho e a formação de cobertura vegetal. O trabalho foi conduzido em um NITOSSOLO VERMELHO no município de Botucatu, São Paulo, Brasil. O delineamento experimental foi o de blocos casualizados em esquema de parcelas subdivididas, sendo as parcelas o fator manejo do solo (em plantio direto e em escarificação) e as subparcelas o fator período de avaliação (quatro e 18 meses após a escarificação) com quatro repetições por tratamento. Os resultados indicaram que, após o período de quatro meses, a escarificação reduziu significativamente a resistência do solo à penetração, até a profundidade de atuação das hastes do escarificador (0,30 m), e, após o período de 18 meses, o efeito da escarificação sobre a resistência do solo à penetração ocorreu apenas na camada superficial do solo (0,05 e 0,10 m). em área cultivada em sistema plantio direto, o efeito do preparo do solo com escarificador sobre a resistência à penetração tende a desaparecer no período de 1,5 anos. A quantidade de matéria seca na superfície do solo, em plantio direto, foi 30% superior ao solo com antecedente de escarificação pelo período de quatro meses.
