Exposição neonatal a drogas ototóxicas e possíveis alterações auditivas

Introduction: Scientific evidence indicates that neonatal exposure to ototoxic drugs cause hearing loss in newborns. Objective: To characterize the use of ototoxic antibiotics in newborns (NB), treated in the Neonatal Intensive Care Unit (NICU) and evaluate possible hearing modifications. Methods: A descriptive cross-sectional quantitative approach, using data from medical records of infants who were at some time in the NICU and used antibiotics, including ototoxic, from January to June 2004 as much as 2010, and the data were compared and analyzed. Parents/guardians of infants born in 2004 were contacted and applied a questionnaire containing questions about the children’s hearing. These children were submitted to audiological evaluation. Results: There was significant reduction in the time of use, the amount of antibiotics prescribed to newborns and Vancomycin prescription in 2010 compared to 2004. The hearing tests of 13 born in 2004 showed: sensorineural hearing loss in only 2 (one with moderate hearing loss and descending configuration in pure tone audiometry and the other with bilateral cochlear impairment); audiometric thresholds within the normal range in 11 patients, and the presence of otoacoustic emissions in 9. In Evoked Auditory Brainstem Response (ABR) no changes were observed. Conclusion: The reduction in the time of use, the amount and types of antibiotics observed may be related to the adoption of a Protocol in 2008, by the service. In contrast, auditory alterations may be related to a neonatal exposure to antibiotics in 2004.

Estudo da viabilidade técnica, econômica e ambiental da substituição de um banco de resistências elétricas de aquecedores por uma caldeira alimentada por biomassa de paletes residuais na indústria de laminação

Given the increasing demand for fossil fuels to power the engines of the global economy, and also the slow process of synthesis of oil, it becomes necessary to develop new sources of renewable energy in addition to improve promising sources that already exist, turning them competitive. Based on this, biomass is shown very promising between the most popular energy sources due to its availability, applicability, and above all, the fact of not emitting green house gases when analyzing the whole carbon cycle. In this sense, this work presents, through an environmental, technical and economic analysis, the impact in an aluminum mill of replacing the use of electricity, in one process, by a boiler fueled with biomass from waste process of packaging the finished product with pallets. Thus, besides the reduction of CO2 emissions, financial gains are targeted, since the main goal of the corporations that require such power is to maximize its profits

Proposta de implementação da ISO 14001 em uma empresa química

Due to environmental concerns and the current legal requirements, companies are looking for ways to reconcile economic growth with environmental preservation. The purpose of this project is to show the stages of implementation of ISO 14001 in a chemical company and propose changes in chemical procedures creating goals to be achieved. In this paper, the study for the implementation of ISO 14001 is in Viapol ltda., where the lack of environmental management can cause enormous impact to the environment and may generate air, soil and water pollution. The project resulted in a mapping of all the processes and a broad survey of waste and emissions, generating proposals to change some of the processes and and creating programs to achieve the goals and objectives proposed in the Environmental Policy. Adopting an environmental management system (EMS), the company will reduce costs by decreasing the amount of raw material used, shooting down on waste disposal and the amount of it, and increasing productivity. By committing to the implementation of the EMS, companies will be demonstrating a proactive approach to environmental issues and enrich its image to consumers’ point of view

Análise de ciclo avançado com seqüestro de carbono

The energy is considered one of the most important elements in the human´s life providing the survival as well as the well being. Nowadays, the technologies destined to generate power burn fossil fuels which pour gases (carbon dioxide among them) that contribute to the global warming phenomenon. Several research groups and universities have been studying different methods for generating power with low carbon dioxide emissions, including the possibility of burning zero-carbon fuels. In this text, it has been put attention to the Advanced Zero Emission Power Plants (AZEP) which separate the CO2 (from the gases involved in the power generation), compress it, dehydrate it and store it in appropriate reservoirs. The goal of this study was to find a possible solution to produce CO from CO2, activated by solar energy; the reaction between CO and steam generates a syngas comprised of H2 and CO2, which can be separated by chemical and/or physical processes. The text also contains a study concerning the compressed air energy storage power plant (CAES) and come up with its modification to C[CO2]ES. This power plant stores CO2 directing it to a reverse combustion process to produce CO which is headed to a syngas reactor to produce CO2 and H2. Hydrogen is separated and carried to the thermal cycle to generate power with low carbon emissions

Avaliação dos gases de efeito estufa a partir do carvão

This paper addresses the context of emissions of Greenhouse Gases (GHG) from activities related to Coal, called fugitive emissions. The survey of factors, development, analysis, and suggestions for controlling emissions are conducted in order to reduce risks to the environment and people around it. The greenhouse gases absorb radiation, emitted by the Earth’s surface, and hinder their escape into space. This process is essential to terrestrial life. Increasing the concentration of those gases in the atmosphere has led to an increase in the terrestrial temperature. A selection of processes that emit gases and the study and development of calculations for measuring fugitive emissions applied in different sources from coal are performed. The greenhouse gases can be released from the extraction, processing, storage, and transportation of fossil fuels to the end consumer. Coal has 4 main fugitive factors: mining, post-mining, oxidation at low temperature, and uncontrolled combustion. The coal formation process produces methane (CH4) and carbon dioxide (CO2), being the methane, the main greenhouse gas from the coal mining and handling. The types of activities and the weight of each in the issuing process are observed. It is also made comparisons between the countries with the highest emissions rates. Are evaluated what has been done and what is needed to decrease emissions, for example the use of gas as an alternative fuel for energy generation

Medidores inteligentes: o primeiro passo em direção as redes inteligentes

Smart grids are the focus of major study today because of the necessity of modernization in electrical systems and reduction of greenhouse gas emissions that increases global warming. Reaching the best deployment method, you must first of all know the current electrical system and how to use them for the benefit of this new technology. Preparing the action plan we should be aware of the main points of smart grids in each step of the electricity system - generation, transmission and distribution. Analyzed these topics, this work will focus on the first step in the implementation of the smart grids: the smart meters, tool which is already being implemented in Brazil. The main characteristics and applications of these devices, as well as their communication structure with the core distributors will be showed during the paper. Finally, we present a case study which will be discussed and analyzed based in the results obtained with the implementation of smart meters in the city of Vancouver, Canada, where we have a considerable savings already in the first year, with fully paying the initial investment and still have a profit
