A verdade em Hegel e Marx

What is truth? Is there a single truth or many? Is it absolute or relative? Hegel and Marx give some answers through their works. he hegelian and marxist outstanding guide themselves by the dialectical approach according to the singular understanding of each one. Yet, in Hegel as much as in Marx truth has to be seen in the relation between the subject and the object. Both of them make the efort to solve the dichotomy established by other tendencies about the subject and the object. he concept of process is central in their thought and this points at the historical essence of reality. However, it is plain that such a solution can only come out by the passage of the subject to the object (Hegel) and the other way around (Marx). In this way truth in Hegel and Marx has to be understood as an ongoing making process granting the exercise of freedom (Hegel) and an essentially social activity (Marx).

Trailer: análise da linguagem utilizada por esta peça publicitária cinematográfica

This final project intends to discourse about the cinematographic publicity piece that is the trailer and its main features. Its relation with the publicity is studied so we can understand how this relation occurs, once the trailer is found in between the cinema and the publicity. The trailer features are exposed, such as the persuasive features, so it becomes evident the importance of studying this advertising tool from a broad perspective. In addition, we seek to determine its aesthetics, its compositional characteristics and their relevance in movie marketing. The paper discusses briefly about the universe of the movie marketing, as a way of situating the trailer as a tool in a set of publicity techniques that help in selling movies. A case study is conducted, involving the analysis of 5 trailers from different categories of gender, in order to capture the essence of the overall trailer, such from the persuasive perspective as the audiovisual perspective. Finally the is the addition of a current universe of characteristics that can be found in the contemporary trailers, grounded by theorists and film scholars that accompanied the evolution of this advertising tool

Rerrefino de óleo lubrificante usado

The lubricant oil used in engines of internal combustion must be, periodically, changed. Its mainly function in the engines is to reduce the friction between the pieces, but its presence also promotes the cleanness and the refrigeration of the equipment. These attributions, at the end of some cycles of operation, make the oil to be dirty, that is, full of contaminating substances such as water, gasoline, diesel, additives, oxidized hydro-carbons and rests of metals, not being recommended, therefore, its discarding in the environment. Thus, all the used lubricant oil that leaves the automobiles engine has been thrust, waiting for a solution. The pollution generated by the discarding of a ton of used oil per day in the soil or in the rivers is equivalent to a domestic sewer of 40 thousand of people. The indiscriminate burning of the used lubricant oil generates significant emissions of metallic oxides, besides other toxic gases, like the dioxin and sulphur oxides. In this context, the mean objective of this essay was to effectuate the rerrefine of the used lubricant oil, aiming the increase of its life cycle and consequently contributing for the reduction of the environmental pollution. According to the used process, it was possible to get a rerrefine oil, of good quality, which physicistchemistries properties are in compliance with the norms of NBR and ASTM

Subsídios para elaboração de plano municipal de gestão de resíduos sólidos orgânicos para o município de Rio Claro-SP

The research aims to propose grants for development of Municipal Plan for the Management of Organic Solid Waste generated in the municipality of Rio Claro. The research universe was composed of organic waste generators establishments (markets and grocers). From the registry of commercial establishments provided by the municipal government were identified who presented this typology, which totaled 38 establishments. In this universe the interview was conducted in 15 establishments obtained by directed sampling based on the characteristics of size, type and location. The data collected were the amount generated, disposal of waste, waste separation, collection frequency, reasons for the disposal of waste, frequency of purchase of products. From the data obtained in the field, we estimated the total generation of organic waste in this segment for the municipality. Then, the estimated costs for implementation and operation of a composting center, a way to subsidize the implementation of the management plan was carried out. We opted for the aerobic composting process by the simplicity of operation and because it is a technique already known. The average waste generation was established by tracks (size) with: stores up to 4 boxes (classified as small) generate on average 1511 kg / month, 40% of organic waste, the 5-9 boxes (small/midsize) generate on average 4338 kg / month, 35% organic and the 10 to 19 boxes (midsize) generate on average 7647 kg / month with 32% organic. In total establishments generate 105 t/ month of waste, with 35t / month of organics. 94% of establishments are in font segregation of waste into recyclable, organic and waste, indicating that the proposed management of organic waste is amenable to application without many changes in existing routine in stores. Recyclables are sent for recycling through selective collection held by the cooperative, while the organics are destined for the landfill and feed. The results indicate...

Análise do plano de radioproteção em radioterapia

Ionizing radiation is used nowadays in various sectors such as agriculture, industry and medicine. The main specialties of medicine which use radiation are the diagnostic radiology, nuclear medicine and radiotherapy. Radiotherapy is a therapeutic modality that is a well established feature for the treatment of malignant disease or not. However, the inadvertent use of ionizing radiation can produce deleterious effects that result in sequels that compromise the welfare of the people involved. The analysis of radiological protection emphasizes the importance of avoiding inappropriate exhibitions aimed at protecting the health of patients, the professionals involved and the general public. The basic principles of radioprotection are justification, optimization and restriction for individual dosage. The departments of radiotherapy are regulated in accordance with specific technical standards of the National Commission of Nuclear Energy (CNEN), which during the inspection for issue and renewal of the authorization of operation requires the submission of a radioprotection plan, this document that requires great demand of time, and has generated much debate among professionals in medical physics, given the difficulties encountered in their preparation. After examining the radioprotection plan of some radiotherapy services, as suggested in order to guide those responsible for drawing up these plans, especially beginners in the career of the physics of radiation, this paper presents a model plan that is in line radioprotection it requires the Technical Standards of CNEN and can easily be the reality of appropriate services

Perfil dos pesquisadores PQ do CNPQ da área de Engenharia de Produção

There is a need for ongoing evaluation of the researchers not only engineering and production in all areas of knowledge engineering. To check the quality and veracity of scientific production, the CNPq is a brazillian government agency designed to evaluate researchers, classify them and give the encouragement and incentive for their research. This study quantifies the CNPq researchers in the field of Production Engineering according to the time of operation in research, number of guidelines for masters and doctoral, number of articles in national and international journals or magazines and congresses. The classification of these researchers, according to the proposed quantification, is confronted with the level of research they have in CNPq. The researcher starts his career at level 2, after it spending levels for 1D, 1C, 1B reaches to the highest level 1A. The main conclusion to be drawn from this study is that excellent researchers with a significant number of guidelines, bitter years in the early levels because of the rules of the CNPq which only allows a researcher to achieve the highest levels after many years of research

Oralidade e eventos de letramento relacionados à leitura: práticas sociais constitutivas da escrita

This research is the result of a senior research project and longed to verify if the ways of child‘s participation in orality in classroom and the literacy events related to reading would make possible to child construct a discursive relation with the writing. Besides it investigated the conception of 20 teachers from second year from primary school about orality and literacy and also identifies which theory purposes could be discerned in one of these teachers exercise. The methodology used was the qualitative approach, with exploratory- descriptive character, and based in system of references methodological of bibliographic research and collecting of facts research. The corpus of this research constituted in deflagrate element that stimulated the search for methodology answers which could clear the possible essence of set of problems evidenced. The results indicated that the ignorance of some basic conceptions that imbricate in teaching Portuguese language, principally in orality development, reading of writing by some individuals was alarming component parts, since many of them mediate the teachinglearning process of numberless individuals. Considering that orality and literacy play fundamental function in social interactions, this research has the intention to contribute for teacher‘s continuous formation, just as help them in development of students‘ linguistic competences, and elucidate them about the importance of literacy, besides to make public the more recently theoretical subsidies about this subject

Implementação da metodologia TPM em uma indústria do setor de higiene pessoal, saúde e beleza

This work presents a project of Action Search in a consumption industry of the sector of personal care, health and beauty. Following the implementation steps of Autonomous Maintenance Pillar of TPM methodology, stands for Total Productive Maintenance, this work aims to ensure the advancement of some machines in a production line of the company to the next steps of the methodology implementation, demonstrating the results achieved by the TPM. In the company in question, the TPM has been implemented in the past but lost strength over the years and some of its concepts were abandoned, producing then a drop in the equipments efficiency, increased wastes and breaks in the processes, as well as loss in product quality. Then, the need arose to restart the implementation process from the beginning, to strictly follow all the steps of the methodology, ensuring increased efficiency of equipment and processes. Through training and a changing in the company culture, it was possible a joint effort between Operation and Maintenance in order to enhance the knowledge of the operators on their machines. Initially, it was developed a general cleanliness program of equipments so that it could be possible to find the anomalies in the process. Subsequently, operators and maintainers were trained to detect anomalies, enabling equipments to work under their basic conditions of operation and subsequently building provisional standards of equipment cleaning, lubrication and inspection. Through the improvement presented by some indicators such as OEE, wastes, bankruptcies and unavailability, it was proved the importance and the positive effects of TPM implementation in manufacturing
