Esta pesquisa teve como objetivo caracterizar os padrões de consumo de bebida alcoólica e a prevalência de indicadores de ansiedade e depressão, em universitários. Foram investigados 200 alunos, em série consecutiva, oriundos dos cursos de Biologia, Ecologia, Educação Física e Pedagogia. Os métodos consistiram na aplicação de escalas especializadas para verificação de padrões de consumo de álcool e sintomas de ansiedade e depressão, respectivamente, o SADD (Short Alcohol Dependence Data) e a HAD (Hospital Anxiety and Depression Scale). Os resultados mostraram que, dos 200 alunos, 17 (8,5%) apresentavam comportamento de uso abusivo de álcool, com riscos para a saúde física e mental. Ainda, 53 alunos (26,5%) revelaram indicadores positivos de ansiedade e 16 (8%), de depressão. Destes 53 alunos com indicadores positivos de ansiedade, 8 (15,1%) faziam uso abusivo de álcool e, dos 16 alunos com sintomas depressivos, 8 (50%) tinham comportamento de consumo abusivo de álcool, com riscos para a saúde física e mental. Os autores concluíram que o uso abusivo de álcool pode estar associado à presença de sofrimento psíquico, principalmente ansiedade e depressão. E propõem que se discuta a necessidade de criação de um Serviço de Saúde Mental para atendimento da comunidade universitária.

Non-intrusive methods of diagnosis, such as spectral analysis of the radiation emitted by the system, have been used as a viable alternative for determining the temperature of combustion systems. Among them, the determination of temperature by natural emission spectroscopy has the advantage of requiring relatively simple experimental devices. Once Chemiluminescent species are formed directly in the excited state, the collection and recording of radiation emission spectrum is enough to determine the temperature (CARINHANA, 2008). In this study we used the process of making direct comparisons between the experimental spectra obtained in the laboratory from the plasma of alcohol, and the theoretical spectra plotted from a computer program developed at the IEAv. The objective was to establish a fast and reliable method to measure the rotational temperature of the radical C2*. The results showed that the temperature of the plasma, which in turn can be taken as the rotational temperature of the system, is proportional to the pressure. The temperature values ranged from ca. 2300 ~ 2500 K at a pressure of 19 mmHg to 3100 ~ 3500 K for the pressure of 46 mmHg. The temperature values are somewhat smaller when we consider the theoretical spectrum as a Lorentzian curve. The overlap of the spectra was better when using the profile curve, but still were not exactly superimposed. The solution to improve the overlap of the theoretical with the experimental spectra is the use of a curve that has the convolution of two profiles analyzed: Lorentzian and Gaussian. This curve is called the Voigt profile, which will also be implemented by programmers and studied in a next work

From the beginning of the century, with the advent of the flex fuel car, successor fluctuations in oil prices and the rise of awareness of the impending shortage of fossil fuels, the alcohol sector begins to reappear in the panorama of national economy making Brasill reaches the point of becoming a leading exporter of this product. Ethanol assumed the role of such importance in Brazilian exports, which Petrobras through the Growth Acceleration Program (PAC) has made investments in the Brazilian pipeline network to better ensure the production of ethanol to major ports. The means of transport in pipelines are safe and inexpensive, but require careful evaluation in its implementation, they may lead to negative social and environmental impacts. Thus, the purpose of this project is to propose the best route for an ethanol pipeline connectin the Tietê-Paraná, leaving the municipality of Santa Maria da Serra (SP), to the Planalto Paulista Refinery (REPLAN), located in Paulinia (SP), belonging to the passage of ethanol export corridor, currently under revelopment. The technique used for the development of the stroke is the association of multicriteria evaluation, the geographical information system (SIG) and geotechnologies. This study presented three possible layouts for the ethanol pipeline, highlighting the best option, in addition, demonstrated the suitability of the area to receive projects of similar nature to a pipeline
