Análise experimental da resistência à corrosão e da velocidade de corrosão: uma proposta pedagógica

In this work it is proposed the use of a chemical activity, in which a corrosion process occurs, aiming to provide to the student relationship among the learning concepts and corrosion phenomena that occur everyday. It is suggested that the experiment development is based on Vygotsky theory, so that students work in groups, which may facilitate social interaction among students and results discussion among groups under professor guidance. This proposal can provide the involved concepts learning, as well as student training such as a critical and reflexive individual.

Propriedade intelectual e as indústrias criativas: cultura digital, regulamentação e as licenças públicas

When we think of a transposition from a traditional culture industry to the new coherence of the creative industries, a number of new parallel discussions arises, encircled by the reconfiguration of the value chain of such industries and, not only, but also due to a change on creation coherence of a product whose most valuable input is creativity. Therefore, as a mechanism through which such creativity is valued, the intellectual property becomes one of the key elements of this debate, mainly in a world where the coherence of distribution transcends the physical copies towards the digitization of content. From this initial debate, the present article seeks to weave the main relations between the theme of creative industries and the intellectual property, describing the adversities of a deficient regulation and its consequences on the creative industries production, indicating the existing alternatives and questioning the balance between two forces: the collective and the individual rights.

Trabalho e saúde: o cotidiano dos catadores de lixo reciclável

The present article is an investigation / action regarding the working conditions for pickers of recyclable waste in a medium-sized city in the state of São Paulo, mainly on the health / illness process, problems related to social security and conditions of autonomy and citizenship. We use the constructs of social psychology as theoretical. The recycling of urban garbage, as the literature indicates, is not being treated as just part of the solution to environmental problems, but also has been characterized as a source of income and livelihood for many people, with no other options in life. From the interviews were semistructured, and with the method of analysis the meaning core were identified issues related to the holding of by scrap collectors, prejudice existing in relation to the activity performed, poor housing conditions, the need to social recognition and the difficulty of recyclable garbage collectors in forming a group in which they can articulate and fight for their demands. With this study, we intended to indicate suggestions for improvements in these health professionals and encourage individual and collective reflections on the condition of meetings and also through the distribution of leaflets.

Application of an auditory steady-state response test to evaluate the attenuation of hearing protection devices

This research aims to present a new method to get real attenuation of hearing protection devices, with good reproducibility and a small standard deviation, without relying on skills and cooperation individual. Thus the authors performed tests in 10 individuals without protection and after with two kinds of ear protections (ear plug and ear muffs), to get the threshold limit value in each of the 3 stages. For this, the research used an electrophysical exam, normally used in speech therapy, named ASSR (auditory steady-state response). The principle of this exam is put on individual’s head 3 electrodes, to capture electrical signs directly in auditory nerve. In summary, the authors presented the final results. The method proposed by ANSI (American National Standards Institute) indicated an attenuation of 27.6 dB for ear plugs, while the value found in this work was 16 dB; and for ear muffs, the ANSI method indicated 29.8 dB while the value found here was 28.5 dB.

Propostas e currículos estaduais de educação física, avanços e limites no trato de futebol

Football is a sporting phenomenon that unites the collective to individual, because besides the needs of teamwork, it requires several physical individual abilities. The unpredictability of each match turns it into a fascinating and unique sport. Indeed, this is the most popular and admired sport in all over the world, covering a huge amount of fans and practitioners. Curriculum documents are a new and unprecedented fact in history of Physical Education, so it sought as study object investigate and analyze is being treated in many curriculums proposes of seven Brazilian States (Goiás, Maranhão, Pernambuco, Rio de Janeiro, Rio Grande do Sul, Sergipe e São Paulo) and the Distrito Federal. This study has a qualitative character, using documentary research, because it consists by analyze of curriculum documents. As results, stands out the difference between guiding principles in curriculums. However, all of them are based in a new perspective of Physical Education. With regard to the objectives, was evidenced a consensus among the documents examined, which target as Physical Education objective the formation of critical and autonomous individual, besides your insertion in body culture movements, body culture or movement culture. The results showed that all documents, except of Distrito Federal, mention football as content, only Pernambuco, Sergipe and São Paulo showed a further deepening in the theme. Thus, it is believed that it is essential for a better unfolding of football in Physical Education classes a understanding by the students about this sport, not just as a mere act of running after a ball, but as a social phenomenon broad and contextualized

Allergy to hematophagous arthropods bites

Allergies to hematophagous arthropod bites are inflammatory reactivity to arthropods salivary components. They vary in intensity and quality dependent upon the arthropod species and the individual immune response to specific proteins of the insect s saliva. Individuals who were not previously exposed show mild localized reactions not beyond those expected by pharmacological substances present in arthropods saliva. Allergic reactions are immunological in their nature and the diversity derived from hypersensitivity reactions with different levels of participation of the immune system components. Some are mainly derived from a humoral immune response, and others are based predominantly on T-lymphocyte-mediated. The majority of these undesired biological answers are self-limited, and few may cause a systemic reaction. This article intends to discuss the immunological ingredients of this evolutionary interaction.
