The recycling of used cooking oil is gaining increasing attention as society begins to realize the environmental, economic and social benefits of this activity. The reuse of cooking oil has not only prevented its inappropriate disposal but has also yielded economic and social benefits via the valuation of cooking oil waste as a raw material and the possibility of generating employment and income. This study aims to analyze how cooking oil recycling networks are formed to identify ongoing initiatives of collection and reuse, as well as to understand the processes of both formation and expansion of these networks. At present, a number of Civil Society Organizations of Public Interest (CSOPIs) and nongovernmental organizations (NGOs) are spreading this idea and forming networks among suppliers of used oil (final consumers), collection points, processors (companies that collect, filter and sell the product) and companies that use the recycled oil as a raw material. This study examined two of these organizations (Ecóleo, an NGO, and Triangle Institute, TI, a CSOPI) to obtain a preliminary overview of a number of existing initiatives for the collection and recycling of cooking oil in Brazil and the networks that are being formed around these initiatives, including their dynamics and expansion perspectives. © 2014 PICMET.

Our aim was to discover the most important factors that influence the development of greener products in the mechanical industry, emphasising green design in product creation based on current environmental issues and considering product development as one important aspect of product life cycle management. This model is important to the mechanical industry because this sector relies heavily on raw materials, and recycling products is one way to improve environmental conditions. We used exploratory factor analyses to assess new product development, communication in change management, concurrent engineering, green products design worries and supplier involvement risks perception. The factor analyses initially found 10 constructs, but the 10th was eliminated because it had only one variable, and 5 were eliminated because they yielded Cronbach’s alpha values less than 0.6. To develop this model, we sent questionnaires to 2000 professionals in the Brazilian mechanical industry through LinkedIn discussion groups, mostly to professionals who participated in product development and was received 405 answered questionnaires which 394 was considered valid. The results show the importance of consistently managing product development throughout the entire product life cycle. This includes aspects such as product recycling, green products and using materials that are easy to recycle, from the very beginning of product design. © 2015 Taylor & Francis

The aim of the present study was to produce biodiesel from mixtures of cooking oil and provide a possible environmental solution for the region of Campinas (state of São Paulo, Brazil) based on the theory of environmental cost accounting (ECA). Cooking oil collected from homes in Campinas was mixed with ethanol at a ratio of 7:1 and transesterified at 60 °C for one hour for the obtainment of biodiesel using NaOH as a catalyst. The results of the physicochemical analyses demonstrated that the biodiesel possessed characteristics close to those required by Brazilian standards. A recent survey carried out in the city of Campinas revealed that residents are not concerned with the increased of environmental impact and ecological costs in the region caused by the disposal of used cooking oil, which is discarded in sewers and soil. Urgent action is recommended, beginning with raising awareness among the population and the implementation of a policy to determine the storage, periodic collection and use of cooking oil for the production of biodiesel. This fuel could be used for buses, trucks and machines or sold to fuel distributors, offering a savings of US$ 0.8 to 4.5 millions. Campinas could then gain environmental credits and become a sustainable city. Moreover, used cooking oil constitutes low-cost biodiesel with no consumption of raw materials and will reduce worldwide criticism directed at Brazil regarding the use of oleaginous plants for biodiesel production. © 2011 Elsevier Ltd.

Systemic arterial hypertension (SAH) is considered to be the greatest risk factor for the development of neuro-cardiovascular pathologies, thus constituting a severe Public Health issue in the world.The Low-Level Laser Therapy (LLLT), or laser therapy, activates components of the cellular structure, therefore converting luminous energy into photochemical energy and leading to biophysical and biochemical reactions in the mitochondrial respiratory chain. The LLLT promotes cellular and tissue photobiomodulation by means of changes in metabolism, leading to molecular, cellular and systemic changes.The objective of this study was to analyze the action of low-level laser in the hemodynamic modulation of spontaneously hypertensive rats, in the long term. Animals (n = 16) were randomly divided into the Laser Group (n = 8), which received three weekly LLLT irradiations for seven weeks, and into the Sham Group (n = 8), which received three weekly simulations of laser for seven weeks, accounting for 21 applications in each group. After seven weeks, animals were cannulated by the implantation of a catheter in the left carotid artery. On the following day, the systemic arterial pressure was recorded. The Laser Group showed reduced levels of mean blood pressure, with statistically significant reduction (169 ± 4 mmHg* vs. 182 ± 4 mmHg from the Sham Group) and reduced levels of diastolic pressure (143 ± 4 mmHg* vs. 157 ± 3 mmHg from the Sham Group), revealing a 13 and 14 mmHg decrease, respectively. Besides, there was a concomitant important decline in heart rate (312 ± 14 bpm vs. 361 ± 13 bpm from the Sham Group). Therefore, laser therapy was able to produce hemodynamic changes, thus reducing pressure levels in spontaneously hypertensive rats. © 1996-2014, Sociedade Brasileira de Cardiologia.

This paper presents the results of an investigation in four Brazilian States on the adoption of Risk Management practices in projects with different complexity levels. The field research involved 415 projects from nine different economic sectors. Data was gathered through a questionnaire applied to managers and project team members. Results showed that there are significant and positive impacts in the adoption of Risk Management practices on project success. It also showed that there is dependence between perceived success and the presence/absence of a risk manager, i.e., the presence of a risk manager has positive impacts on project success. The major limitation of this study concerns the methodological choice: non-probability sample survey based on respondents perception. The work promotes the integration between Risk Management practices and projects performance, providing a basis for further studies in other sectors and areas of project knowledge.

The objective of this study was to identify whether major multinational companies in the Brazilian market, focused primarily on higher income classes, have promoted some kind of innovation, particularly disruptive innovations, to meet the emerging low-income market, impacting the operation management and/or supply chain of these multinationals. To this end, a multiple case study method was used at Nestlé, Unilever and Johnson & Johnson. Results showed that multinational companies operating in the Brazilian market have not promoted disruptive innovations directed to the base of the pyramid, once they felt that the "D" and "E" classes are not attractive enough to justify investments in product development, directing investments preferentially to the "C" class through small changes in products and distribution. This way, no evidence of disruptive innovations was found; only sustainable and incremental innovations linked to the adequacy of existing products.

Consumption of mobile phones has become a consumer fever in Brazil with more than 190 million devices connected at the national market in 2010. This impressive figure leads to an important question: what is the final destination of these devices at the end of their lifecycle? The main purpose of this paper is to evaluate consumer's behavior in terms of mobile phones discard and recycling in Brazil based on (i) a literature review of the main practices and programs involving reverse logistics of mobile phones currently in place nationwide; and (ii) a quantitative survey carried out in São Paulo state in order to seeking the consumer's perception concerning mobile phones recycling and other factors that also influence their behavior in this regard. The survey results showed that although 60% of the respondents know that a mobile phone can be recycled, only 7% have already recycled his / her old device. It was also possible to identify the main factors that could contribute to increase the mobile phones recycling and also the most convenient collecting points according to the respondents' answers. © 2013 PICMET.

In acute respiratory discomfort syndrome (ARDS) patients, prone position improves oxygenation in more than 70% of the cases. It is well known that prone position promotes a lot of pulmonary changes, including pulmonary mechanics, so we hypothesized that there is the necessity to optimize the ventilatory parameters after the patient is placed in prone position, especially the positive end expiratory pressure (PEEP) values. The objective of this study valued the influence of the prone position at the calculation of the ideal PEEP, given a title by the best pulmonary complaisance and he compared the pulmonary alterations of mechanics, of oxygenation and of ventilation in the positions supine and prone.Prospective study, taken place in the Irmandade Santa Casa de Misericrdia de So Paulo Intensive Care Service. Three fases have been compared. Fase 1: in supine position, after the best PEEP calculation. Fase 2: two hours after the patient was placed in prone position and the best PEEP was calculated. The patient was kept for 6 hours in this position. Fase 3: after this time, patient was placed in supine again and after two hours, a new best PEEP calculation and arterial gas analysis was done. And then fase1 versus fase 2, fase 2 versus fase 3, fase 3 versus fase1 were compared.There were no differences in the PEEP values found in all study fases: fase 1 = 14 4.43; fase 2 = 14.73 4.77 and fase 3 = 13.65 4.92.There were no differences in best PEEP values between prone and supine position. Therefore, there is no need to recalculate the PEEP value after each position change.
