Nanomaterials handling presents enormous challenges for the risk management in research and productions of new materials. However, there is a lack of data about the impacts of these new materials on human health and in the environment. In this scenario, a number of efforts have been made to mitigate the adversities and provide guidelines for the risk management associated with nanomaterials. This paper aims to give a broad overview and comparison between the main proposals in the literature. The methodology was a systematic analysis comprising 17 proposals for risks management with nanomaterials. The results indicate, although there is no consensus on the metrics used to characterize these risks, the adoption of the precautionary principle and the focus of the Control Banding stands out among the documents examined. © 2013 Taylor & Francis Group.

The objectives of datacenter consolidation are cost reduction and superior services. A datacenter consolidation plan includes minimizing investments in IT infrastructure and buildings and reducing power consumption related to cooling. Such a process requires scalable planning and implementation. Virtualization is the most popular and cost-effective technology for datacenter consolidation. In this article, the author runs a cost-benefit analysis of virtualization and datacenter consolidation using the Global Virtual datacenter online calculator and VMware's ROI CO ((for) return on investment/total cost of ownership) calculator version 3.0. © 1999-2012 IEEE.

Problems related to the use of personal protective equipment (PPE), specially the use of protective gloves for the manual sugar cane cutting, motivated this research, made possible by a tripartite negotiation involving the Ministry of Labor, the Union of Rural Workers and the Employer's Association of sugarcane agribusiness. The main objective was to evaluate, from an ergonomics perspective, the impact of use of the gloves during the manual cane sugar cutting, raising questions on safety, effectiveness and comfort. The research was carried in a sugarcane industry of São Paulo for two seasons involving 47 workers who made a qualitative analysis of acceptance of four models of protective gloves. The methodology included the use of semi-structured interviews, questionnaires and field observations and the experimental determination of the coefficient of static friction developed between the gloves and the surfaces of the machete handle. The main results indicate the general inadequacy of the gloves currently used forcing the employees to improvise. Workers found the glove of leather and nylon scraping the best reported for comfort in use. The overall results highlight the problem of detachment of test standards for the manufacture of PPE, ignoring users and the activity to be performed. © 2012 - IOS Press and the authors.
