The main goal of this work is to evaluate the realization of the linguistic phenomenon of preposition and also to investigate how current normative pressures influence the production and the perception of processes of variation and change in Brazilian Portuguese. We analyze the use of prepositions a and para in verbal complementation contexts in contemporary journalistic texts from São Paulo’s press – the web newspapers. The contexts considered are constructions with complements of direction, movement with transference, material transference, and verbal/perceptual predicators (Berlinck, 1996; Corrêa, Cançado, 2006). Because written texts tend to be more conservative (i.e. more normative) this research provides an important linguistic investigation that contributes to the sociolinguistic knowledge of the language. However, the newspapers also tend to reflect the use, so they constitute a privileged place for us to understand the conflicting relationship between ‘norm’ and ‘use’. Besides this, the research is relevant for General Linguistics for considering linguistic and extralinguistic factors which determine the use and frequency of the prepositions, like syntactic-semantic relations between the preposition, the verb, the complement, and the text genre. We collected data from web newspapers from Araraquara, with small and medium circulation. Based on previous results, we have ascertained the predominance of the use of the preposition a in the newspapers from São Paulo in the 20th century. However, we have also ascertained representative records of variation... (Complete abstract click electronic access below)

In recent decades the rise of the tools of information and communication technology (ICT) has been notorious. Currently ICTs are an important educational tool and is associated with the development of teaching methods courses in basic and higher education. Given the influence that these tools are currently engaged in several sectors, this project aimed to assess the frequency and manifestations of ICT that have been employed in the teaching of histology in the Schools of Dentistry of São Paulo. The virtual page of 43 Higher Education Institutions (HEI) was analyzed to search for links to sites of histology. With this assessment only 4 virtual domains were found which was present a narrow range of virtual tools such as hypertext, graphics, quizzes and lessons in electronic formats. Later, by sending a questionnaire to 46 teachers of histology of the Universities of São Paulo, were analyzed for the presence or absence of a site of discipline, mode and frequency of use of ICTs in education, and the value that teacher attaches to these tools. From the responses obtained were concluded that teachers who have websites in general have no interactivite tools and many seem to ignore the real representation of interactivity in teaching and the possibilities of applications of ICTs. However most teachers recognize the importance of education mediated by virtual tools

The treatment of domestic and industrial effluents through Wastewater Treatment Plants (WTPs) generates a residue termed sewage sludge, rich in organic matter, high-volume, occasionally containing pathogens and heavy metals. The sludge generation can minimize the benefits brought by the treatment of sewage, because this residue does not always receive appropriate treatment before final disposal. The disposal is another problem related to sludge. Landfills generally does not have physical space and alternatives such as the use in agriculture requires an intense treatment that could be in many cases operational or economic unfeasible. The objective of this work is the theoretical research about the processes of stabilization of the sludge by anaerobic digestion and the methanogenic activity during the process. Through analysis of each step and contemplating each relevant factor in anaerobic digestion process in order to optimize them, we proposed a theoretical model of reactors capable of stabilize the sludge, reduce its volume and eliminate pathogens. The obtained configuration consists of two anaerobic reactors connected in series. The first one operates in the range mesophilic temperature (35 ° C) and has higher hydraulic retention time (25 days) working primarily in the stabilization of organic matter present in the sludge and producing biogas, whereas the second one operates in the thermophilic range (55 ° C) in order to eliminate pathogens, and to reduce the volume. The hydraulic retention time in the second reactor is lower (10 days). Both mesophilic and thermophilic processes were efficient in what was proposed, promoting the stabilization of organic matter present in the sludge and significant reduction of pathogens. As a final step with the sludge previously digested, it is indicated a final dehydration... (Complete abstract click electronic access below)

According to ABIPA (2009), Brazil is currently among the major producers of reconstituted wood panels, with one of the main factors for this condition, its climate and its large land area, which allows the cultivation of forests, which provide raw materials for these industries. To establish that market as power, Brazil has invested about R$ 1.3 billion in the last 10 years, yet designed an investment of 0.8 billion dollars over the next three years (BNDES, 2008). With the new investments in this segment, we expect a growth of about 66% in the resin consumption of urea-formaldehyde (GPC, 2009) which should also result in major investments by the companies producing this polymer. Currently employees are mainly three types of resins in the production industry panels, as follows: Urea-Formaldehyde Resin (R-UF), melamine-formaldehyde resin (R-MF) and Phenol-Formaldehyde Resin (R-FF). Especially the cost factor, the urea-formaldehyde resin is the most used by companies producing reconstituted wood panels. The UF-R is a polymer obtained by condensation of urea and formaldehyde reactors (usually batch type), characterized by being a thermosetting polymer which makes it very efficient for bonding wood composites. The urea-formaldehyde polymer, to present a quite complex, it becomes very difficult to predict the exact chain resulting in the process of condensation of urea with formaldehyde, so that a greater knowledge of its characteristics and methods for their characterization can result in greater control in industrial processes and subsequent decrease cost and improve the quality of reconstituted wood panels produced in Brazil

The volume of liquid effluent generated in cattle slaughterhouses is quite high and cannot be released untreated in water bodies due to its high pollution load of predominantly organic origin. To minimize the environmental impacts of its industrial wastewater and meet the local environmental legislation, abattoirs shall make the treatment of these effluents. The present work aims to develop the study of a reactor by sequential batch pilot scale, in order to optimize their performance in treating wastewater from a cattle slaughterhouse. The treatment system used was developed and installed in the Laboratory of Wastewater Treatment, in Faculty of Science and Technology UNESP, Presidente Prudente campus. The procedure used followed the operation of sequential batch reactors, in which all processes and treatment operations occurring sequentially in a single unit, by establishing specific operating cycles, which comprise the following separated phases: aerobic reaction, anoxic reaction, sedimentation and emptying. Aiming to improve the quality of treatment was planned the addition of coagulant Poly Aluminum Chloride (PAC) in the reactor, by determining their optimal dosage by Jar-test trials. Were prepared four steps with specific operating cycles: step one or acclimatization (10 hour of aeration, one hour and 30 minutes of sedimentation and 30 minutes for exchanging the effluent); step 2 (6 hours of aeration or aerobic phase, 4 hours and 45 minutes of stirring or anoxic phase and 1 hour and 15 minutes for sedimentation and exchange effluent); step 3 (2 hours and 30 minutes of aeration, 8 hours and 15 minutes of stirring and 1 hour and 15 minutes for sedimentation and exchange) and step 4 (2 hours of aeration, 8 hours and 45 minutes of stirring and 1 hour and 15 minutes for sedimentation and exchange)...

Com a revolução industrial e tecnológica, o trabalho braçal foi e vem sendo substituído por máquinas e equipamentos eletrônicos, na intenção de poupar o ser humano e diminuir gastos e despesas com salários e aumento da produtividade. Devido a esses fatores, o trabalho tornou-se repetitivo, o que possibilitou o aparecimento de doenças como a L.E.R./D.O.R.T.. Esse contexto despertou o interesse na realização desta pesquisa, cujo objetivo é relacionar essas patologias e suas incidências à personalidade das pessoas através de um sistema denominado Eneagrama. Por meio de uma revisão de literatura nas áreas de Ginástica Laboral, L.E.R./D.O.R.T. e Eneagrama, foi possível obter informações que levou à analisar que os Tipos do Eneagrama 1 (Perfeccionista), 3 (Bem Sucedido), 8(Confrontador) e 9 (Preservacionista), apresentam alta probabilidade de incidência de L.E.R./D.O.R.T.. Os Tipos 4 (Romântico), 5 (Observador), 6 (Questionador) e 7 (Sonhador), apresentam baixa probabilidade de incidência. Enquanto que o Tipo 2 (Prestativo) é neutro quanto ao resultado. Concluindo assim, que o aparecimento dessas doenças pode estar relacionado a um ou mais tipos específicos de personalidade, e que aplicando esse sistema nas empresas, acompanhado da realização da Ginástica Laboral, podemos contribuir na diminuição de casos como esses.
