    The new technologies developed for the reduction of the use of fossil fuels in automobiles can be classified by the way these try to reduce the use of energy. In the search for the technologies for the conservation of it the environmental problem is added, that although it is not the subject of this presentation results decisive for the evaluation of the performance of type of technology. The development of technologies in this field has followed three basic tendencies. First: The efficient improvement of internal combustion motors, which consist in the control and constant monitoring the functioning of these motors in order to determine the strictly necessary consumption for the motor operation in accordance with its load conditions. Second, the development of a system that utilizes alternate fuels, as is the case of hybrid vehicles, that utilize gas turbines that can burn these fuels. Third the development of electric driven and energy regeneration systems avoiding the use of fossil fuels. A fourth tendency could be considered, which consists in determining the best way of controlling and using the transportation time, with all the implicit benefits. The purpose of this paper is to answer all these questions beginning with a detailed revision of the main technological innovations developed by the leading car manufacturers at world level, such as BMW, Mercedes Benz, Ford, etc. concerned in bringing to the market the best vehicles that burn less or none fossil fuels and at the same time comply with the every day more strict standards on the environmental pollution subject. Through these innovations the advantages and disadvantages of each one of them are set forth, with special emphasis in the technologies that, to our concern, will be the most convenient to promote in the years to come.

    The current economic-political conditions in the oil market are spurring on future alternative energy models worldwide, one of which is fuel batteries. This technology is foreseen to have several applications in portable and stationary services. Previous studies have reported on the slowness of Mexican legislation, compared to international legislation, on the collection and treatment of spent domestic batteries. Legislation on the issue is limited to a project for a Non-Mandatory Mexican Norm proposed since 2006, without having been implemented at the time the present document was written. In addition to the toxic environmental impact of the lack of regulation, it also represents a waste of energy, impacting the finances of users who throw away batteries with a significant residual energy charge (>60 %). This work analyzes recent Mexican energy reform to regulate the use of alternative technologies. Compared to international legislation, the basis of the Mexican legislation is unclear and incomplete, lacking technological consulting from governmental scientific institutions and clear, complete legislation adhering to international principles for the environment and society. These characteristics pose a risk to regulations and their application in Mexican society, and involve a loss in the benefits of applying clean technologies having better performance, a continued reflection of slow technological, economic, environmental and social advancement.

    Full Text Available Pretendo aqui, muito preliminarmente, reunir alguns argumentos favoráveis à multiplicidade de oportunidades de aprender que o aluno pode encontrar hoje em ambientes de aprendizagem mediados por novas tecnologias. Centro-me principalmente na desconstrução de algumas resistências pedagógicas (EVANS, 2001 ainda persistentes entre nós como “transmissão de conteúdos”; agarramento a uma única teoria; fixação na aula instrucionista; extirpação/endeusamento de processos avaliativos, etc. Procuro ver, em um vasto âmbito de ofertas teóricas, componentes atualmente ressaltados na discussão tecnológica em vigor, com o objetivo de indicar oportunidades de reconstrução muito aproveitável de autores e clássicos, uma vez que aprender bem não foi algo inventado pelas novas tecnologias; sempre existiu e os grandes pedagogos tiveram consciência disso, insinuando infinitas maneiras de aprender bem (DEMO, 2008. As novas tecnologias proporcionam oportunidades ainda mais ampliadas, em meio também a enormes riscos e desacertos. O que menos interessa aqui é incidir em panaceias tecnológicas, bem a gosto do consumismo neoliberal. Interessa, porém, explorar novas oportunidades de aprendizagem, bem mais centradas na atividade dos alunos, flexíveis, motivadoras e capazes de sustentar processos de autoria e autonomia.

    Full Text Available O Programa de Estudos Pós-Graduados em Gerontologia/PUC-SP desenvolve pesquisas em diversificadas linhas algumas das quais têm em comum o acolhimento à questão das novas tecnologias no envelhecimento. São investigações de caráter interdisciplinar que envolvem docentes-pesquisadores, orientandos de mestrado e de iniciação científica. Na área da educação a distância, a PUC-SP inaugura um trabalho em que o idoso interessado em avançar em seus conhecimentos é recebido em um ambiente virtual de aprendizagem, em que pode participar de cursos avançados de aquisição de novas linguagens e de navegação na Internet, cujas consequências são o investimento em uma via mais digna para o envelhecer no sentido de esse idoso sentir-se um ser ligado aos novos tempos em que a interatividade digital traz-lhe possibilidades ilimitadas de contatos com o outro, com o mundo enfim. A pesquisa sobre a inclusão cibersocial do idoso mostra o que significa colocar o idoso em contato com a Internet, quando este recebe, por meio das redes sociais, ofertas de várias ordens, e equipamentos que contornam limitações de ordem física ou motora. Além disso, o registro digital da memória do idoso, de sua história e referências também podem constituir conteudos preciosos para pesquisas. A relação do idoso com a informática pode situá-lo como um ator, produtor e reprodutor no ciberespaço. Isso significa que as vantagens do uso do computador fazem o idoso ganhar novo sentido na vida, na medida em que pode assim preencher o vazio causado pelas perdas que lhe vão ocorrendo, possibilitando que ele redimensione seu olhar para o presente e futuro. Palavras-chave: o sujeito-idoso nas novas tecnologias; novas tecnologias e envelhecimento; o idoso na educação a distância; internet na velhice.

    Full Text Available Constant increase of the number of automobiles causes demand for individual materials to get on the rise, thus giving an impulse to the development of recycling logistics. Used automobiles get disassembled and individual parts which can be used as raw materials or additives get recycled. Automobile tires can be reclaimed or vulcanized. In July 1978 the environmental-friendly "Blauer Engel" or "Blue Angel" symbol was first introduced for reclaimed tires. Later, emblems were introduced for other recycled automobile pans. The awarding of the emblem is being controlled and approved by authorized institutes, because the emblem rightfully designates traffic safety.

    This talk discusses the technical options available for automobiles within the next 5 to 10 years. With the objective to reduce consumption and pollution, several alternative approaches are presented and analyzed using simplified but realistic calculations. Main emphasis is laid on CO{sub 2} emission of the complete energy transformation path from the primary energy carrier to the energy dissipated in test cycles. It is shown that no single optimal solution exist but that a trade-off between consumption, pollution and cost must be made for each specific situation. (author) 17 figs., 2 tabs.

    Full Text Available Code Recognition Device is a security device for automobiles. It responds only to the right sequence of codes that are keyed from the key pad. This closes the electrical circuitry of the automobile and enables it to start. If a wrong key is touched, it resets the device which disengages the electrical circuit of the automobile from the power supply. The device works properly on closing all the doors of the automobile, otherwise it cannot start. Also, once the automobile is in operation, opening of any door will disengage the device and the engine will stop. To restart the engine, the doors must be closed and the codes rendered sequentially-in this case the codes are 1974.

    Full Text Available Today’s automobiles leverage powerful sensors and embedded computers to optimize efficiency, safety, and driver engagement. However the complexity of possible inferences using in-car sensor data is not well understood. While we do not know of attempts by automotive manufacturers or makers of after-market components (like insurance dongles to violate privacy, a key question we ask is: could they (or their collection and later accidental leaks of data violate a driver’s privacy? In the present study, we experimentally investigate the potential to identify individuals using sensor data snippets of their natural driving behavior. More specifically we record the in-vehicle sensor data on the controllerarea- network (CAN of a typical modern vehicle (popular 2009 sedan as each of 15 participants (a performed a series of maneuvers in an isolated parking lot, and (b drove the vehicle in traffic along a defined ~ 50 mile loop through the Seattle metropolitan area. We then split the data into training and testing sets, train an ensemble of classifiers, and evaluate identification accuracy of test data queries by looking at the highest voted candidate when considering all possible one-vs-one comparisons. Our results indicate that, at least among small sets, drivers are indeed distinguishable using only incar sensors. In particular, we find that it is possible to differentiate our 15 drivers with 100% accuracy when training with all of the available sensors using 90% of driving data from each person. Furthermore, it is possible to reach high identification rates using less than 8 minutes of training data. When more training data is available it is possible to reach very high identification using only a single sensor (e.g., the brake pedal. As an extension, we also demonstrate the feasibility of performing driver identification across multiple days of data collection

  9. Tecnologia versus ação

    DEFF Research Database (Denmark)

    Villadsen, Kaspar

    2014-01-01

    Oconceito de tecnologia desenvolvido por Michel Foucault ocupa uma posição ambígua na pesquisa organizacional contemporânea. Por um lado, a noção foucaultiana de “tecnologias de poder” tornou-se uma ferramenta analítica chave para pesquisadores organizacionais que buscam compreender...... as complexidades do poder na vida organizacional. Por outro, a abordagem foucaultiana à análise organizacional foi amplamente criticada por negligenciar a ação dos atores humanos, que figuram antes como meros instrumentos do poder, do discurso ou das tecnologias de poder. Este artigo argumenta que essa crítica...... amplamente aceita faz pouca justiça ao pensamento de Foucault sobre tecnologia e organização. Reavaliando o próprio conceito de tecnologia de Foucault, em especial no contexto de suas palestras de 1978, argumentamos que a crítica convencional da “negligência da ação” é mal orientada. Para fugir a essa...

    There are over 12 million automobiles in Canada, each travelling over 16,000 km annually. The value of motor vehicles and parts produced in Canada accounts for over 6% of the gross domestic product, and vehicle-related sales account for the largest proportion of Canadian retail activity. The environmental issues related to the high impact of the automobile on Canadian life are discussed. In the manufacture of motor vehicles, over 2 billion kg of metal are used a year; although much of this comes from recycled materials, some depletion of nonrenewable resources is required. It is also estimated that 66-105 GJ of energy are needed to produce a motor vehicle, equivalent to as much as 20% of all the energy consumed during the vehicle's lifetime. Environmental impacts result from this use of resources and energy, including land disturbances and air pollution. Land use impacts are also those related to appropriation of urban and rural land for roadway and service uses, plus pollution of adjoining lands by road runoff. In 1990, the transportation sector used 29% of end-use energy, of which retail gasoline sales for motor vehicles accounted for 54%. Environmental impacts from oil refining, fuel combustion, and waste disposal are described, and programs to mitigate these impacts are outlined. Significant reductions in automobile emissions have already occurred from the increased use of emission control devices, improved fuel efficiency, and stricter standards. Further improvements are possible via such means as better manufacturing procedures, increased recycling of automobile components, better inspection and maintenance, and use of alternative fuels and alternate transportation modes. 35 refs., 3 figs., 4 tabs

    Full Text Available This paper is a brief overview of the evolution of the global automotive industry during the 20th century, with reference to the main manufacturers, oil crises of 1970-1980, and also the global financial and economic crisis that began in 2008. The analyzed period covers the rise of the Asian Continent, beginning with Japan, then South Korea and more recently the emerging countries: China and India. What was predicted 20-25 years ago, became reality: Asia becomes the economic centre of the world, surpassing unexpectedly fast even the Euro-Atlantic area. Regarding Romania, the revival delay of the automobiles industry, led to the loss of the trucks and bus industry, and after a much awaited rehabilitation of car production, this has stuck now at an unsatisfactory level.

    Automobile mechanics have been exposed to asbestos in the past, mainly due to the presence of chrysotile asbestos in brakes and clutches. Despite the large number of automobile mechanics, little is known about the non-malignant respiratory diseases observed in this population. The aim of this retrospective multicenter study was to analyse the frequency of pleural and parenchymal abnormalities on high-resolution computed tomography (HRCT) in a population of automobile mechanics. The study population consisted of 103 automobile mechanics with no other source of occupational exposure to asbestos, referred to three occupational health departments in the Paris area for systematic screening of asbestos-related diseases. All subjects were examined by HRCT and all images were reviewed separately by two independent readers; who in the case of disagreement discussed until they reached agreement. Multiple logistic regression models were constructed to investigate factors associated with pleural plaques. Pleural plaques were observed in five cases (4.9%) and interstitial abnormalities consistent with asbestosis were observed in one case. After adjustment for age, smoking status, and a history of non-asbestos-related respiratory diseases, multiple logistic regression models showed a significant association between the duration of exposure to asbestos and pleural plaques. The asbestos exposure experienced by automobile mechanics may lead to pleural plaques. The low prevalence of non-malignant asbestos-related diseases, using a very sensitive diagnostic tool, is in favor of a low cumulative exposure to asbestos in this population of workers.

    Full Text Available Investment volume is considered as an important factor in regional development under current conditions. Logistical infrastructure which ensures a complex transport, distributive, information and other services exerts a significant influence on regional investment attractiveness. Lack of clear vision on development and execution of development strategy for logistics infrastructure from the side of regional authorities results in unwillingness of large federal and transnational companies to provide investments in infrastructure projects. Network of automotive transport terminals is one of the main elements in logistics infrastructure. The network allows to optimize a flow of material goods from the point of their origin to the point of their consumption with the lowest possible costs and the required level of service. Automobile transport is one of the main objects of transport infrastructure and it is characterized by rather high flexibility in comparison with other types of transport facilities that preconditions its widespread application. Network of automobile fleets (terminals has been formed for redistribution of goods traffic within the concerned regions. The purpose of the present research is to develop a mathematical model for formation of transport infrastructure on the territory of regions. The paper proposes an approach for formation of automobile fleet (terminal network on the territory of a large region with due account of the established network of distribution and sorting-out warehouse facilities. A model has been developed for solving the problem pertaining to minimization of aggregate costs related to maintenance of automobile fleets, delivery of goods to and from distribution and sorting-out warehouse facilities to consumers, ferry of empty trucks and goods handling. The model makes it possible to determine optimal number and location area of automobile fleets (terminals while accounting for their possible locations, capacity

    Tavares, Jorge; Velez, Fernando J.; Ferro, João M.

    2008-01-01

    Some applications of Wireless Sensor Networks (WSNs) to the automobile are identified, and the use of Crossbow MICAz motes operating at 2.4 GHz is considered together with TinyOS support. These WSNs are conceived in order to measure, process and supply to the user diverse types of information during an automobile journey. Examples are acceleration and fuel consumption, identification of incorrect tire pressure, verification of illumination, and evaluation of the vital signals of the driver. A brief survey on WSNs concepts is presented, as well as the way the wireless sensor network itself was developed. Calibration curves were produced which allowed for obtaining luminous intensity and temperature values in the appropriate units. Aspects of the definition of the architecture and the choice/implementation of the protocols are identified. Security aspects are also addressed.

    Tozzi, L.; Sekar, R.; Kamo, R.; Wood, J. C.

    1983-01-01

    Computer simulation results are presented for advanced automobile diesel engine performance. Four critical factors for performance enhancement were identified: (1) part load preheating and exhaust gas energy recovery, (2) fast heat release combustion process, (3) reduction in friction, and (4) air handling system efficiency. Four different technology levels were considered in the analysis. Simulation results are compared in terms of brake specific fuel consumption and vehicle fuel economy in km/liter (miles per gallon). Major critical performance sensitivity areas are: (1) combustion process, (2) expander and compressor efficiency, and (3) part load preheating and compound system. When compared to the state of the art direct injection, cooled, automobile diesel engine, the advanced adiabatic compound engine concept showed the unique potential of doubling the fuel economy. Other important performance criteria such as acceleration, emissions, reliability, durability and multifuel capability are comparable to or better than current passenger car diesel engines.

    We propose an automobile driven by piston motion, which is driven by water-laser coupling. The automobile can load a solar-pumped fiber laser or can be driven by ground-based lasers. The vehicle is much useful for the use in other planet in which usual combustion engine cannot be used. The piston is in a closed system and then the water will not be exhausted into vacuum. In the preliminary experiment, we succeeded to drive the cylindrical piston of 0.2g (6mm in diameter) on top of water placed inside the acrylic pipe of 8 mm in inner diameter and the laser is incident from the bottom and focused onto the upper part of water by the lens (f=8mm) attached to the bottom edge.

    In the field of automobile control technology, electronic was first adopted for the electronic fuel control as an answer to the exhaust gas regulations. The operations of the driving system, frame system or the automobile itself which is the combination of the two were optimized by adding sensors, computers, actuators, etc. to alleviate the burden of the driver, offering easier drivability and confortableness. For local driving control, measurement of distance up to obstacle has been practiced using the ultrasonic radar sensor. Research and development of microwave radar sensor have been carried out for years. Automatic driving has been a dream technology, and the study for the technology was started since early times. Remarkable progress was made recently in the navigation system for traffic control in wide area. New automobile traffic information communication and other systems are being developed. Historical description is made on the control and information systems for road transportation, dividing the period into the 1st, 2nd and 3rd generations. 10 references.

    Full Text Available Se trata de un artículo sobre la evolución histórica de la tecnología en neonatología, resaltando aspectos conceptuales y reflexivos sobre el impacto tecnológico en el proceso de cuidar. A pesar de que en los últimos años, la tecnología ha contribuido para mejorar la supervivencia de prematuros extremos nacidos con muy bajo peso, algunas veces da lugar a una modalidad de atención mecánica e impersonal, que se contrapone a cuestiones de índole ética y humana. Se propone una discusión crítica y reflexiva acerca del uso de la tecnología en el cuidado neonatal, destacando sus implicaciones y adecuaciones a las necesidades del recién nacido. Se concluyó que lo que determina si una tecnología es buena o mala, si deshumaniza, despersonaliza o interpreta como objeto al sujeto a cuidar, es la manera como es utilizada, convirtiéndose en imprescindible el perfeccionamiento y la actualización de los profesionales de la salud. En este ejercicio análitico es necesario reflexionar acerca de nuevas maneras de brindar cuidados, utilizando el arte, la sensibilidad y la creatividad en la adaptación y humanización de las tecnologías.

    finishing of automobiles is an important aspect. There have been considerable reductions of weight in automobiles by the use of composites components replacing heavy metallic components. Fenders previously based on metal have been replaced with plastic and painted with the same colour shade as of the metallic body, this has eps for proper adhesion of the paints on the plastic fender to avoid chipping off the paint form it. This paper discusses the necessary processes required for finishing of an automobile along with the corrosion protection measures. Automobiles contains a variety of engineering materials, engine main body fuel tanks connecting rods heat radiators and other mechanical parts are made from different types of engineering alloys having varying chemical compositions. Other parts like dashboard, front panel and other are made from composites. The main body made from cold roll ed steel having various contours 'c' it due to the different designs is the potential site for corrosion attack, The main body is exposed to the hostile environment through out its life period. An automobile is given a particular finish with a view to counter the hostile environments as they are not limited for plying in a limiting conditions and are taken to different weather conditions in one day thus facing severe stresses and strain. Thus it is essential that an automobile before rolling 'out of the assembly line should properly corrosion resistant and aesthetically pleasant also. Finishing for automobiles being very specialized, the main requirement being maximum durability with minimum numbers of coats baked, at the fastest possible schedule. High gloss and range of good eye catching colours being important to increase sales appeal. In the near past the car finishes were based on alkyd-amino resins baking materials and force drying lacquers, which have excellent appearance originally and maintain it on aging. The finishing system for the synthetic baking type may consist of

    The new EU objectives included in its Circular Economy Package and the Spanish 2016-2022 Waste Plan define a new scenario of transformation of municipal solid waste management. They also define the hierarchization of waste treatment: reduction, reuse, recycling, energy valorization and, as a last resort, landfill. The use of new technologies is contributing to this transformation, including both separation at source and collection and treatment. Improved traceability of wastes via the use of sensors, technological innovation in management and the emergence of a fifth bin for selective collection of organic wastes are only some of the new elements that are increasingly common in Spanish cities.

    1996-08-08

    The new, rapidly evolving field of industrial ecology - the objective, multidisciplinary study of industrial and economic systems and their linkages with fundamental natural systems - provides strong ground for believing that a more environmentally and economically efficient economy will be more information intensive and complex. Information and intellectual capital will be substituted for the more traditional inputs of materials and energy in producing a desirable, yet sustainable, quality of life. While at this point this remains a strong hypothesis, the evolution of the automobile industry can be used to illustrate how such substitution may, in fact, already be occurring in an environmentally and economically critical sector.

    The objective was to establish a systematic framework for measuring and understanding cognitive distraction in the automobile. Driver distraction from secondary in-vehicle activities is increasingly recognized as a significant source of injuries and fatalities on the roadway. Across three studies, participants completed eight in-vehicle tasks commonly performed by the driver of an automobile. Primary, secondary, subjective, and physiological measures were collected and integrated into a cognitive distraction scale. In-vehicle activities, such as listening to the radio or an audio book, were associated with a low level of cognitive workload; the conversation activities of talking to a passenger in the vehicle or conversing with a friend on a handheld or hands-free cell phone were associated with a moderate level of cognitive workload; and using a speech-to-text interfaced e-mail system involved a high level of cognitive workload. The research established that there are significant impairments to driving that stem from the diversion of attention from the task of operating a motor vehicle and that the impairments to driving are directly related to the cognitive workload of these in-vehicle activities. Moreover, the adoption of voice-based systems in the vehicle may have unintended consequences that adversely affect traffic safety. These findings can be used to help inform scientifically based policies on driver distraction, particularly as they relate to cognitive distraction stemming from the diversion of attention to other concurrent activities in the vehicle. © 2015, Human Factors and Ergonomics Society.

    Full Text Available The muffler is the main part of the Automobile Exhaust System, consisting of fibrous and porous materials to absorb noise and vibrations. The exhaust gas mass coming from the engine can produce resonance, which may be the source of fatigue failure in the exhaust pipe due to the presence of continuous resonance. The modes on the muffler should be located away from the engine’s operating frequencies in order to minimise the resonance. The objective of this paper is to determine the frequencies that appear at the modes, which have the more adverse effect during the operation of the automobile. An impact test has been conducted by applying the force using a hard head hammer, and data generated have been used for plotting a graph of the transfer functions using MATLAB. Six points have been selected, namely 1, 2, 3, 4, 7, and 11 on the muffler for the impact test. The collected data from theses six points have been analysed for the addition of damping. Results suggests that increasing the mass increases the damping and lowers the modes of the transfer function.

    Full Text Available The article analyzes the way in which the modern car-advertisement defines the identity of women as potential purchasers – to whom it is designed to get through. The research includes language and iconic instruments by which this type of advertisement aims to create a feminized market of products formerly recognized as traditionally masculine. The identification of the addressee of each publicity material might be subsumed under a set of stereotypes, thus enabling advertisers to get across their message using the code of addressee’s own values. The present paper concentrates on the linguistic specifity of the ads for high-tech goods (automobiles targeting the feminine public and eventually points out their high degree of markedness according to the sex of addressees. Discourse analysis and a closer look at linguistic means appearing in French, Spanish and Polish automotive commercials both reveals a stereotyped woman’s image and shows how they happen to perpetutate it.

    Descriptions of safety engineering defects of the kind that compel automobile manufacturers to initiate a recall campaign were evaluated by individuals on a set of risk characteristic scales that included overall vehicle riskiness, manufacturer's ability to anticipate the defect, importance for vehicle operation, severity of consequences and likelihood of compliance with a recall notice. A factor analysis of the risk characteristics indicated that judgments could be summarized in terms of two composite scales, one representing the uncontrollability of the damage the safety defect might cause and the other representing the foreseeability of the defect by the manufacturer. Motor vehicle defects were found to be highly diverse in terms of the perceived qualities of their risks. Location of individual defects within the factor space was closely associated with perceived riskiness, perceived likelihood of purchasing another car from the same manufacturer, perceived likelihood of compliance with a recall notice, and actual compliance rates.

    2013-01-01

    Full Text Available This paper evaluates product efficiency in the Spanish automobile market. We use non parametric frontier techniques in order to estimate product efficiency scores for each model. These scores reflect the minimum price for which each car could be sold, given the bundle of tangible features it offers in comparison to the best-buy models. Unlike previous research, we use discounted prices which have been adjusted by car dealerships to meet sale targets. Therefore, we interpret the efficiency scores as indicators of the value of the intangible features of the brand. The results show that Audi, Volvo, Volkswagen and Mercedes offer the greatest intangible value, since they are heavily overpriced in terms of price/product ratios. Conversely, Seat, Kia, Renault and Dacia are the brands that can be taken as referent in terms of price/product ratios.

    There are several new energy sources to produce electricity. One of them is the wind energy, which has reached huge commercialization in worldwide. There are in Mexico some zones with high speed wind, which can be used in a short term. This has been proved by the wind pilot power plant of La Venta, Oaxaca, where production costs of US 4.3 cents per kilowatt-hour (kWh) have been obtained. These costs are among the lowest in the world. By the other hand, among the main uses of solar energy, including both thermal and photovoltaic techniques, the biggest thermo-solar utility, with 350 megawatts (MW) of capacity, is remarkable. This is the plant located in the Mojave Desert, California, USA. In Mexico there is big potential, which can make an important contribution to supplies of electricity. Biomass is another important renewable source, particularly the use of solid municipal waste, the livestock and the wood waste. Finally, other alternate technique is represented by the fuel cells, though it is not properly renewable. However, considering its modular and low environmental impact characteristics, it can get a wide commercial development in the next decade.

In this domain famous land-use-transportation studies (or ‘grand transportation studies’ are, unfortunately, still prevailing - a vicious circle of self-fulfilling prophecy of congestion, road building, sprawl, congestion and more road building. Until recently, it was commonly thought that investment in public transport was not economically sustainable and that focusing on the development of the automobile industry and financing the construction of roadways stimulated economic growth. In this paper we clearly show that automobile industry is now overcapitalized, less profitable than many other industries (and may become even less profitable in the future, that transport market is characterized with huge distortions (more than a third of motor-vehicle use can be explained by underpriced driving, while new road investment does not have a major impact on economic growth (especially in a region with an already well-developed infrastructure, and that pro-automobile transport strategy inexorably incurs harmful global, regional and local ecological consequences.

    Recently, increases in energy prices have made energy conservation and efficiency improvements even more essential than in the past. However, consumers experience difficulty in obtaining reliable information regarding energy efficiency, so that many countries have implemented regulations to enforce energy-efficiency grade labeling. In this study, consumer preferences regarding energy efficiency grades are analyzed by the mixed logit and MDCEV model based on the revealed preference data of past automobile purchases. Findings show that consumers rationally apply information on energy efficiency grades when purchasing automobiles. However, they tend to show inefficiency in automobile usage patterns. This study discusses political implications of energy efficiency policies as they might impact consumer behaviors of automobile purchase and usage. - Highlights: ► We model discrete choice model to evaluate energy-efficiency grade regulation. ► Consumers apply information on energy efficiency grades when purchasing automobiles. ► However, they tend to show inefficiency in automobile usage patterns. ► The policies for efficient automobile usage are discussed.

    Full Text Available No mundo contemporâneo, ou, mais precisamente, nesta era da informação instantânea e simultânea, o raciocínio geográfico tem se destacado e, simultaneamente, se alterado por meio de novos aspectos sociais e tecnológicos. O presente estudo foi realizado com dezenove docentes atuantes em vários cursos de formação de professor de geografia de instituições públicas e privadas de diversas regiões do Brasil. Esses docentes têm utilizado as novas tecnologias e/ou pesquisado e produzido trabalhos a respeito delas no ensino de geografia. Diante disso, perseguimos o estudo na busca de se responder a seguinte indagação: novas tecnologias e raciocínio espacial: mas o que isso tem a ver? As tecnologias atuais, como veículos de informações, não têm a finalidade de desenvolver o “saber pensar o espaço” ou de realizar o “raciocínio espacial”, mas mesmo sem essa finalidade as pessoas aprendem geografia, pensam com a mediação dessas tecnologias. O ensino de geografia contribuiu para a formação de diversas pessoas por meio do desenvolvimento do raciocínio espacial realizado em duas diferentes escalas, do local ao global, mostrando articulações entre os diversos níveis de abstração, desde o espaço do trabalho até sua inserção em uma sociedade que se internacionaliza de maneira acelerada.

    Full Text Available O artigo investiga a estruturação de uma nova cultura de memória, a qual inverte a lógica metafísica com que se pensou a relação entre tecnologia e experiência nas ciências sociais. Com as recentes tecnologias da vida e da informação, a concepção do corpo humano como algo que se constitui à margem de um aparato tecnológico declina em credibilidade. Com isso, um dos principais projetos da metafísica ocidental, a saber, a estruturação de um campo de experiência e conhecimento livre de suportes técnicos, malogra em seu humanismo tecnofóbico. A partir de uma apreciação do conto Memento Mori, de Jonathan Nolan, e do filme Amnésia, de Christopher Nolan, analiso a relação entre memória e escritura, corpo e arquivo na contemporaneidade. O objetivo é perceber as tensões e oscilações implícitas na tentativa de instauração de uma mnemotécnica pretensamente pós-humana ou pós-orgânica.

O objetivo do referido projeto é analisar e socializar discussões sobre a técnica e a tecnologia a partir de um viés filosófico. Salientase que o projeto foi desenvolvido por aluno de curso técnico integrado ao ensino médio, com o intuito de aproximação dos conceitos em questão. Optou-se pela investigação do tipo bibliográfica, a partir do diálogo com teóricos como Dusek, Lévy, Platão, entre outros. Com base na análise feita, chegou-se a alguns achados: primeiro, não se pode desconsiderar, na conceituação de técnica, características humanas, como a razão, a liberdade, a criatividade, o discernimento, a escolha e a ambição, aspectos necessários para facilitar a condição e o trabalho humano. Segundo, a técnica está amplamente ligada à tecnologia, pois aquela precede a criação desta e participa de sua utilização. E, por fim, o complexo sistema tecnocrático só pode de fato existir na presença constante das técnicas, mas compreende-se que o governante fundamentalmente tecnocrata é também, na verdade, um estudioso, um aluno. Para que tal governante exista, é necessária uma educação bem fundamentada e completa. Essa é exatamente a relação entre técnica, tecnologia e tecnocracia.

  11. Can urban rail transit curb automobile energy consumption?

    International Nuclear Information System (INIS)

    Lin, Boqiang; Du, Zhili

    2017-01-01

    With the rapid development of China's economy and the speed of urbanization, China's automobile sector has experienced rapid development. The rapid development of the automobile sector has increased energy consumption. According to the results of this paper, automobile energy consumption accounted for about 10.73% of total energy consumption in China in 2015, about 3.6 times the proportion a decade ago. With the deterioration of urban traffic conditions, relying on expanding the amount of vehicles and city road network cannot solve the problem. Urban rail transit is energy-saving and less-polluting, uses less space, has large capacity, and secure. Urban rail transit, according to the principle of sustainable development, is a green transportation system and should be especially adopted for large and medium-sized cities. The paper uses the binary choice model (Probit and Logit) to analyze the main factors influencing the development of rail transit in Chinese cities, and whether automobile energy consumption is the reason for the construction of urban rail transit. Secondly, we analyze the influence of urban rail transit on automobile energy consumption using DID model. The results indicate that the construction of urban rail traffic can restrain automobile energy consumption significantly, with continuous impact in the second year. - Highlights: • Investigate the main factors influencing the building of rail transit for Chinese cities. • Analyze the influence of urban rail transit on automobile energy consumption by DID model. • The results indicate that the construction of urban rail traffic can restrain automobile energy consumption significantly.

    This study is aimed quantify dissipated power in a damper of automobile suspension to predict energy harvesting potential of a passenger car more accurately. Field measurements of power dissipation in a regenerative damper are still rare. The novelty is in using the broad database of real road profiles, a 9 degrees-of-freedom full-car model with real parameters, and a tyre-enveloping contact model. Results were presented as a function of road surface type, velocity and road roughness characterised by International Roughness Index. Results were calculated for 1600 test sections of a total length about 253.5 km. Root mean square of a dissipated power was calculated from 19 to 46 W for all four suspension dampers and velocity 60 km/h and from 24 to 58 W for velocity 90 km/h. Results were compared for a full-car model with a tyre-enveloping road contact, full-car and quarter-car models with a tyre-road point contact. Mean difference among three models in calculated power was a few per cent.

    Evaluating country manufacturing location attractiveness on various performance measures deepens the analysis and provides a more informed basis for manufacturing site selection versus reliance on labor rates alone. A short list of countries can be used to drive regional considerations for site-specific selection within a country. Design/methodology/approach: The two-step multi attribute decision model contains an initial filter layer to require minimum values for low weighted attributes and provides a rank order utility score for twenty three countries studied. The model contains 11 key explanatory variables with Labor Rate, Material Cost, and Logistics making up the top 3 attributes and representing 54% percent of the model weights. Findings: We propose a multi attribute decision framework for strategically assessing the attractiveness of a country as a location for manufacturing automobiles. Research limitations/implications: Consideration of country level wage variation, specific tariffs, and other economic incentives provides a secondary analysis after the initial list of candidate countries is defined. Practical implications: The results of our modeling shows China, India, and Mexico are currently the top ranked countries for manufacturing attractiveness. These three markets hold the highest utility scores throughout sensitivity analysis on the labor rate attribute weight rating, highlighting the strength and potential of manufacturing in China, India, and Mexico. Originality/value: Combining MAUT with regression analysis to simplify model to core factors then using a “must have” layer to handle extreme impacts of low weight factors and allowing for ease of repeatability.

Para subsidiar essa discussão foram analisadas a abordagem dos sistemas sociotécnicos elaborada inicialmente por Trist, Emery e colaboradores do Instituto Tavistock; a abordagem da adequação sociotécnica oriunda da perspectiva construtivista da tecnologia e a abordagem dos híbridos sociotécnicos proposta por Latour. O argumento central é que o desenvolvimento de TS deve considerar as tramas de relações, em que tanto os aspectos sociais como técnicos estão imbricados nas organizações, evitando as ênfases de cada corrente e considerando a mediação sociotécnica como principal unidade de análise nos estudos em TS. A motivação dessa discussão é que a aplicação das abordagens sociotécnicas, sem o equilíbrio aparente das mediações sociotécnicas, parece fazer das TS somente mais uma dentre muitas outras abordagens “alternativas”, como os próprios estudos na área têm criticado.

    2003-05-01

    Over the last three decades, automobile manufacturers have made a lot of progress in specific fuel consumption and engine emissions of pollutants. Yet the impact of these improvements on vehicle consumption has been limited by increased dynamic performances (maxi-mum speed, torque), increased safety (power steering and power brakes) and increased comfort (noise and vibration reduction, electric windows and thermal comfort). Because of this, the real CO{sub 2}-emission levels in vehicles is still high in a context where road transport is a major factor in the balance sheet of greenhouse gas emissions, thus in complying with the inter-national climate convention. Although European, Japanese and Korean manufacturers signed an important agreement with the European Commission for voluntarily reducing CO{sub 2} emissions from their vehicles, with a weighted average emission goal by sales of 140 grams per km on the MVEG approval cycle by 2008, it has to be noted that the European procedures for measuring fuel consumption and CO{sub 2} emissions do not take accessories into account, especially air-condition ng (A/C). The big dissemination of this equipment recognized as a big energy consumer and as using a refrigerant with a high global warming potential ed ADEME to implement a set of assessments of A/C's energy and environmental impact. In particular these assessments include studies of vehicle equipment rates, analyses of impact on fuel consumption as well as regulated pollutant emissions in the exhaust, a characterization of the refrigerant leakage levels and an estimate of greenhouse gas emissions for all air-conditioned vehicles. This leaflet summarizes the results of these actions. All of these studies and additional data are presented in greater detail in the document,-'Automobile Air-conditioning' (ADEME reference no. 4985). (author)

    Full Text Available In response to the present dynamic market, automobile manufacturing industries are constantly evaluating and improving their manufacturing strategies to stay competitive. It is also evident that they evaluate those strategies considering multiple criteria. In one such case, an automobile project manager has to ensure that the selected tire (among the available alternatives complies with the prospective automobile’s performance. This paper presents an approach for the assessment of alternative automobile tires taking into account multiple criteria, such as tire sustainability, tire road performance, environmental issues, tire purchase cost and tire road grip. The presented approach is quite helpful to any decision maker who is interested not only in ranking alternatives but also in establishing the superiority of an alternative over others. The approach also helps to specify the position of each alternative with respect to ideal solution. A case illustration is used to demonstrate an application of the approach.

    1982-03-01

    This paper describes the future role of the automobile from an intercity transportation perspective in multimodal contexts; it identifies courses of action open to Transport Canada officials in support of the suggested role. Discussed here is the automobile's multifaceted role, focussing mainly on its use as a mode of door-to-door travel for short trips, a feeder as well as an adjunct to public modes, a means of avoiding excessible public expenditure in highly subsidized public modes (e.g., rail), and a means for providing basic mobility in regional travel contexts. This study goes beyond the 1979 Transport Canada report with the same title by recommending courses of action that might assist officials in formulating policy, planning and other endeavours. At the outset, updated information is provided on the current status and future outlook of selected important factors that affect the future transportation role of the automobile. Against this background, the relevance of major findings of the 1979 automobile report are reviewed and gaps in knowledge identified. On the basis of this information, a future role for the automobile is discussed, with appropriate courses of action recommended. These recommendations and their institutional/program implications are addressed to Transport Canada in the areas of strategic planning and policy, energy planning, safety and coordination of actions/programs with other federal government departments and provincial governments. 48 refs., 8 tabs.

    This paper focuses on how changes in the economic and regulatory environment have affected production costs and product characteristics in the automobile industry. We estimate "hedonic cost functions" that relate product-level costs to their characteristics. Then we examine how this cost surface has changed over time and how these changes relate to changes in gas prices and in emission standard regulations. We also briefly consider the related questions of how changes in automobile characteristics, and in the rate of patenting, are related to regulations and gas prices.

    Full Text Available This paper analyzes the dynamics of U.S. automobile gasoline consumption since 1975. Using background literature on the history of domestic fuel economy and energy policy, I establish a conceptual model that explains historical trends in adoption of increased fuel economy. I then create a system dynamics simulation model to understand the relationship between increased fuel economy standards and potential changes to gas tax policies. The model suggests that when increases in mandated fuel economy are not conducted in an environment with rising fuel costs, fuel economy improvements may be directly counteracted by shifting tastes of consumers towards larger automobiles with lower fuel economy.

    Full Text Available O texto aborda a relação dos jovens e adolescentes com tecnologias, nem "novas" nem "velhas", e sim instrumentos para informar e comunicar, divertir, auxiliar nos trabalhos escolares. Apesar de reconhecer a familiaridade dessa geração com o que há de mais avançado em termos de tecnologia, aponta a necessidade de se compreender a complexidade desse novo cenário de aprendizagem, que envolve o aprofundamento de conceitos como interatividade e interação, linguagem numérica, multimídia, internet e hipertexto. Na seqüência, faz uma análise do contato dos jovens com essa diversidade de meios, suas implicações no processo cognitivo e suas conseqüências comunicacionais. Finalmente, reconhece que a aprendizagem é hipercomplexa e que - apesar de todo avanço científico - a máquina, mesmo interativa, não pode proporcionar ao indivíduo o aprendizado que lhe proporciona a interação com outras pessoas.The paper discusses how young people relate to technology, not seen as new or old, but as an instrument to communicate and keep informed, amuse and to help in school projects. Although it is clear that the new generations are much more familiarized with new technology, the focus is on the need to understand the complexity of the new scenario, which requires a deeper understanding of the concepts of interactivity, multimedia, internet and hypertext. It is discussed how young people enter in contact with this diversity of instruments. It is stressed, however, that no matter how complex the computer can be, nothing can replace the role of interacting with other people in the learning process.

  4. Reducing automobile traffic: an urgent policy for health promotion

    1998-01-01

    Full Text Available In recent decades traffic injuries have become a leading cause of death and disability the world over. In congested urban areas, the noise and emissions from vehicle engines cause discomfort and disease. More than one billion people are exposed daily to harmful levels of atmospheric contamination. Because internal combustion generates carbon dioxide (CO2 , the automobile is a principal contributor to the greenhouse effect, which has significantly raised the temperature of the atmosphere. Scientists anticipate that in coming decades the greenhouse effect will produce alterations in climate that are very likely to be harmful and possibly catastrophic. Meanwhile, burgeoning traffic and rural and urban highway infrastructures are already among the principal causes of environmental degradation. Urban development, because it is nearly always "planned" to accommodate automobiles rather than people, reduces the quality of life and tears the social fabric. In contrast to private automobiles, public transportation, bicycles, and walking produce little environmental contamination or injury-related morbidity and mortality. These modes of transport involve more physical activity, with its positive health effects, and avoid contributing to the greenhouse effect. The reduction of automobile traffic and substitution of alternative modes of transport are essential policies for health promotion. They should be incorporated in "healthy cities" programs and general economic policies.

  11. Divorce your car: ending the love affair with the automobile

    Energy Technology Data Exchange (ETDEWEB)

    Alvord, K.

    2000-07-01

    This book is a guide for people wishing to liberate themselves from their addiction to cars and the automobile culture. It is a repository of examples and actions that individuals and communities can take to reduce dependence on the automobile. The range of possibilities run from using cars less to not owning one at all. The book provides a humorous yet clear-headed approach to a greener world and maps out the road to how people can live happily ever after by breaking free of 'auto-cracy', without insisting on people in car-dependent countries quit their automotive addiction instantly. Nevertheless, it clearly articulates the connection between automobiles, their arteries (i.e. highways) and effluents (i.e. greenhouse gases and particulate emissions), and the increasing number and severity of natural disasters between the urban renewal and freeway construction that, in the author's view, helped ignite the riots in Watts, Newark and Detroit. The disastrous societal and geophysical effects of the automobile are demonstrated in great abundance, and the mountain of evidence of the systematic abuse of the planet that the book provides is a stunning refutation of the notion that technology is neutral. The automobile is accused of being not only the linchpin of Western and primarily American industrialism and resource extraction, it is also accused of being the chief suspect in a century-long theft of time, conviviality and beauty. How to bring about a change in people's love affair with their cars is difficult to comprehend but this author has a multitude of useful suggestions which seem to suggest that it is possible. There is a list of 104 'selected references' and an extensive list of 'other resources'.

    «La victoria del darwinismo ha sido tan completa que es un shock darse cuenta de cuan vacía es realmente la visión darwiniana de la vida». Esta rotunda frase no parece significar solamente la manifestación de una opinión personal. Pertenece a un editorial publicado en Nature y fïrmado por Henry Gee, uno de sus comentaristas sobre evolución. El motivo de que una revista científica de las más prestigiosas (que se pueden considerar como las mantenedoras de la ortodoxia, haga suyo ese comentario es que las investigaciones más recientes (especialmente en el campo de la embriogénesis han revelado unos fenómenos que han puesto de manifiesto su absoluta incompatibilidad con la teoría darwinista de la evolución. Las consecuencias de esto son obvias, y las precisa otro editorialista de Nature, Philip Ball, en un comentario sobre la secuenciación del Genoma humano: «Los biólogos van a tener que construir una nueva Biología». Tenemos por delante un duro y largo trabajo científico por realizar, pero también tenemos una tarea previa: depurar la Biología de la, tan arraigada, terminología darwinista, cargada de conceptos y prejuicios deformadores de los fenómenos biológicos.

    Many cities have been perplexed with automobile emissions causing them to become non-attainment areas. These cities usually resort to such tactics as trying to get people to car pool. In principle the concept is excellent, however, the American public is not ready to give up the independence of using their own automobile. Reformulated gasolines are presently being produced and plans for additional plants are being made to meet EPA gasoline requirements. How much reformulated gasoline is available? Where is the present production going? Who else has needs? Does Gasohol have any possibilities still? What contribution can other additives make and are there any bright spots on the horizon and if so what are they? All this will be revealed in this talk and paper at ETE. There will also be a panel discussion for others to present their ideas and contribute to the program

    This paper attempts to quantify the effects of airline deregulation in the United States on intercity automobile travel and consequently on the number of highway fatalities. A demand model is constructed for auto travel, which includes variables representing the price and availability of air service. A reduced form model of the airline market is then estimated. Finding that deregulation has decreased airfares and increased flights, it is estimated that auto travel has been reduced by 2.2% per year on average. Given assumptions on the characteristics of drivers switching modes and the types of roads they drove on, the number of automobile fatalities averted since 1978 is estimated to be in the range 200-300 per year.

    This study adopts airflow management technology to improve the local temperature distributions in an automobile to counteract the greenhouse effect. The automobile's temperature can be reduced to almost the outside temperature before the driver or passenger gets into the vehicle. When the engine is idling, the greenhouse-control system can be activated to remove the hot air from the car. An appropriate negative pressure is maintained to prevent stuffiness and save energy. The greenhouse-control system requires electrical power when the engine is idle, and a battery cannot supply sufficient power. An auxiliary solar-power supply can save energy and reduce the greenhouse effect of sunlight, while creating a comfortable traveling environment. It ensures that the engine is not overburdened and increases its service life, conserving energy, protecting the environment and improving comfort

    In assessing the technical/economic feasibility of the direct combustion of vegetable oils in diesel type engines, this paper first points out the good results obtained in performance tests on these fuels in Elsberg engines, and their low sulfur and nitrogen oxides and carbon dioxide emission characteristics. It then assesses the improvements that are necessary in the development of marketable bio-fuel oils that conform to European Communities air pollution standards for automobiles. Further efforts must be made to reduce bio-fuel oil smoke emission levels, to compensate for their lower calorific value as compared with conventional diesel fuels, and to make them compatible with automobile finishing materials - paints and plastics. The paper suggests a set of suitable fiscal policies designed to favour the marketing of bio-diesel fuels based on their favourable pollution abating qualities - low greenhouse gas emissions and biodegradability

    Full Text Available O melhoramento vegetal vem sendo praticado pelo homem há milhares de anos. Entretanto, esse processo de domesticação tornou os vegetais mais susceptíveis a pragas e doenças. O melhoramento clássico permitiu, por cruzamento, a manipulação genética dos vegetais com conseqüente aumento na produtividade agrícola. Recentemente, a tecnologia do DNA recombinante ampliou as possibilidades de integração de genes exógenos ao genoma vegetal, resultando na produção das plantas transgênicas. Apesar das grandes discussões em torno do assunto, essas plantas representam hoje um caminho promissor para o melhoramento vegetal. Inúmeros exemplos de estratégias de transferência de genes conferiram, com sucesso, resistência a herbicidas, vírus, fungos, bactérias e insetos ou produziram um aumento na qualidade dos alimentos. Além das aplicações biotecnológicas, as plantas transgênicas têm contribuído significativamente para o estudo do funcionamento dos genes, tais como a análise da regulação da expressão gênica e o estudo das funções das proteínas codificadas pelos diferentes genes da planta.

  10. Press Coverage of CCS: A New Technology in the Media; Analisis de la Cobertura de la Tecnologia de Captura y Almacenamiento de CO{sub 2} (CAC) en la Prensa Escrita: Una Nueva Tecnologia en los Medios de Comunicacion

    Public knowledge of Carbon Capture and Storage (CCS) technology is very low among the Spanish population. Only 17% of the Spanish said to have heard about CCS. There is also an important percentage of the population who is not sure about the use of CCS as a mitigation option for climate change. In that sense, the media could play an important role in the formation of public attitudes of CCS. The objective of the present work is to identify the picture of CCS transmitted in the Spanish press from January 2005 to July 2008. We carried out a quantitative analysis of a total of 139 press articles, considering different dimensions as the general attitude to CCS, the actors mentioned and their attitude, benefits and risks related to CCS, or the link with climate change. Data show a significant increase of CCS coverage in the Spanish press from 2007. The CCS technology is framed in the climate change context, as a possible solution to reduce CO{sub 2} emissions. The general attitude transmitted is positive: the benefits of the technology are emphasized versus the risks. Nevertheless, data show an important polarization in the attitudes through CCS between environmental NGOs (against it) and all the other actors (in favour). (Author) 5 refs.

    2017-05-01

    Based on the connection mechanism of nodes which automatically select upstream and downstream agents, a simulation model for dynamic evolutionary process of consumer-driven automobile supply chain is established by integrating ABM and discrete modeling in the GIS-based map. Firstly, the rationality is proved by analyzing the consistency of sales and changes in various agent parameters between the simulation model and a real automobile supply chain. Second, through complex network theory, hierarchical structures of the model and relationships of networks at different levels are analyzed to calculate various characteristic parameters such as mean distance, mean clustering coefficients, and degree distributions. By doing so, it verifies that the model is a typical scale-free network and small-world network. Finally, the motion law of this model is analyzed from the perspective of complex self-adaptive systems. The chaotic state of the simulation system is verified, which suggests that this system has typical nonlinear characteristics. This model not only macroscopically illustrates the dynamic evolution of complex networks of automobile supply chain but also microcosmically reflects the business process of each agent. Moreover, the model construction and simulation of the system by means of combining CAS theory and complex networks supplies a novel method for supply chain analysis, as well as theory bases and experience for supply chain analysis of auto companies.

    The objective of this study is to assess the association between average adult body mass index (BMI), automobile travel, and caloric intake in the US in order to predict future trends of adult obesity. Annual BMI data (1984-2010) from the Behavioral Risk Factor Surveillance System (BRFSS), vehicle miles traveled data (1970-2009) from the Federal Highway Administration, licensed drivers data (1970-2009) from the Federal Highway Administration, and adult average daily caloric intake data (1970-2009) from the US Department of Agriculture were collected. A statistical model is proposed to capture multicollinearity across the independent variables. The proposed statistical model provides an estimate of changes in the average adult BMI associated with changes in automobile travel and caloric intake. According to this model, reducing daily automobile travel by one mile per driver would be associated with a 0.21 kg/m(2) reduction in the national average BMI after six years. Reducing daily caloric intake by 100 calories per person would be associated with a 0.16 kg/m(2) reduction in the national average BMI after three years. Making small changes in travel or diet choices may lead to comparable obesity interventions, implying that travel-based interventions may be as effective as dietary interventions.

    This article describes the state of the automobile industry and urban road transportation management in China. It reviews how the automobile industry is evolving to respond to challenges in economic development, environmental regulations, and technological change. The dynamics and barriers resulting from technological change of automobiles in response to reduction of exhaust emissions and energy-efficiency improvement are analyzed. It is argued that consideration of externality costs should be integrated in automobile industrial policymaking and transportation management. Efforts need to be made to use more economic incentives for emissions reduction, and to promote technological change for cleaner vehicle development. This paper questions the current government policy of encouraging private car ownership, and suggests that improvement in public transportation systems, stronger emissions control, and technology innovation on environmental friendly automobile technologies would be relevant to China's drive toward sustainable transportation development. Social inequities resulted from automobile use is also stressed in the analysis

    Full Text Available Com o desenvolvimento da indústria de alimentos, as embalagens têm se aperfeiçoado, indo além de sua função básica de proteger o alimento contra danos mecânicos e contaminações químicas e microbiológicas. Elas têm cada vez mais desempenhando papel de destaque, contribuindo ativamente para a venda de um produto. Assim, as indústrias de embalagens têm procurado atender aos consumidores mais exigentes e juntamente aos centros de pesquisa e universidades, têm investido mais em estudos de novas tecnologias, a fim de prolongar as características de qualidade do alimento, conferir melhor aparência, maior proteção mecânica no embarque, transporte, desembarque e nos supermercados, oferecer embalagens mais compactas, que ocupem menos espaço na geladeira, com abertura e fechamento mais fáceis, e que utilizem materiais de fácil reciclagem ou decomposição no ambiente. Com o objetivo de atender às novas expectativas das indústrias de alimentos e dos consumidores, surgem as embalagens ativas e as embalagens inteligentes. As embalagens ativas são aquelas que interagem de alguma forma com o alimento, seja liberando substâncias conservantes ao longo da vida de prateleira do produto, ou “corrigindo” alguns problemas naturais do alimento, como sabor amargo por exemplo, em que algumas enzimas podem ser adicionadas ao material de embalagem, minimizando este problema e tornando o produto mais saboroso. Já as embalagens inteligentes indicam as modificações químicas às quais os alimentos estão passando, como mudanças de pH, por exemplo, indicando alterações na qualidade do produto.

    This article explores the mechanisms by which firms are interdependent in their intra firm diffusion processes. We argue that intra firm diffusion is strictly different to first adoption in terms of the mechanism by which other firms influence the process. Instead of the dominant epidemic diffusion theories, we propose an alternative one based on competitive interaction. According to it, technology deployment by rivals increases the intra firm diffusion incentive by raising competitive pressures, but also reduces the incentive by lowering the expected profitability of the technology. We test our propositions by analyzing the diffusion of the Automated Teller Machine among the Spanish savings banks between 1986 and 2004. (Author) 35 refs.

    Fuel Cells have emerged in the last decade as one of the most promising new and sustainable natural gas technologies for meeting the energy needs of all the economy sectors into the 21st century. Fuel Cells are an environmentally clean, quiet, and highly efficient method for generating electricity and heat from natural gas. A fuel cell is an electrochemical device that converts the chemical energy of a fuel directly to usable energy (electricity and heat) without combustion. For this reason, the application and use of the fuel cell technology may be the most important technological advancement of the next century. At the beginning of the 2000 year Sociedad de Gas de Euskadi, s. a. started a demonstration project in favour of the high-temperature planar solid oxide fuel cell (SOFC) for domestic micro-CHP utilization. This type is certainly most exacting from the materials standpoint, and it offers the advantage of uncomplicated fuel pretreatment. (Author)

    It turns out of interest to Comision Federal de Electricidad and Petroleos Mexicanos to reduce costs of fuel oil, reducing the viscosity of the residues petroleum of high vacuum distillation emulsifying these with water. The parameters that define the characteristics of the emulsions are mainly the relation of their components, viscosity, size and drop distribution and its stability. The experimental work began producing emulsions in form of lots, using samples of approximately 500 milliliters of vacuum residue. In this first stage, at different concentrations, were examined eight different surfactants, as well as combinations among them, also seven different stabilizers were used. With these tests it has been managed to identify the concentrations, as well as the most adequate relations of surfactants and stabilizers for the production of emulsions of vacuum residues in water. The size and drop distribution has been determined by means of an optical LEICA microscope, model DMLS, that has adapted a photographic system in which an emulsion photo is obtained and, later, a system of analysis of images is used for obtaining of the values of the diameter of the drops present in the emulsion. Finally, by means of statistical software the average size of the particles is obtained, as well as the drop size distribution. The tests results of emulsions that remain fluid are shown and an example of the microstructure of an emulsion of vacuum residue-in-water is given. As well as an example of histogram of the drop size distribution of an emulsion of vacuum distillation-in-water, and another one of the viscosity in function of temperature at different cut efforts in one emulsion of vacuum distillate residue-in-water.

Los parametros que definen las caracteristicas de las emulsiones son principalmente la relacion de sus componentes, viscosidad, tamano y distribucion de gota y su estabilidad. Los trabajos experimentales se iniciaron produciendo emulsiones en forma de lotes, utilizando muestras de aproximadamente 500 ml de residuo de vacio. En esta primera etapa se examinaron, a diferentes concentraciones, ocho surfactantes distintos, al igual que combinaciones entre ellos, tambien se utilizaron siete diferentes estabilizadores. Como estas pruebas se han logrado identificar las concentraciones, asi como las relaciones mas adecuadas de surfactante y estabilizador para la produccion de emulsiones de residuo de vacio-en agua. El tamano y distribucion de gota se ha determinado mediante un microscopio optico LEICA, modelo DMLS, que tiene acoplado un sistema fotografico en el que se obtiene una foto de emulsion y, posteriormente, se utiliza un sistema de analisis de imagenes para la obtencion de los valores de diametro de las gotas presentes en la emulsion. Finalmente, mediante un software estadistico se obtiene el tamano promedio de la particulas, asi como la distribucion del tamano de las gotas. Se muestran los resultados de pruebas emulsiones que permanecen fluidas y se dan un ejemplo de la microestructura de una emulsion de residuo de vacio-en-agua. Asi como un ejemplo de histograma de la distribucion de tamano de gota de una emulsion de residuo de vacio-en-agua. Se muestran graficas de la viscosidad en funcion del esfuerzo de corte a diferentes temperaturas de una emulsion de residuo de vacio-en-agua y otra de la viscosidad en funcion de la temperatura a diferentes esfuerzos de corte de una emulsion de residuo de vacio-en-agua.

  1. Estratégias competitivas e desempenho da indústria automobilística no Brasil

    Directory of Open Access Journals (Sweden)

    Rodrigo Morem da Costa

    Full Text Available Resumo Nos anos 1990, a indústria automobilística brasileira experimentou um processo de reestruturação induzido pela mudança nas estratégias de concorrência das montadoras e pelas transformações na economia nacional. O trabalho analisou como ocorreu esse processo no período 1989-2013 desde uma concepção teórica Evolucionária. A reestruturação levou à redução do hiato tecnológico em veículos e em processos de fabricação, frente ao observado em países avançados. Isto se manifestou por meio de investimentos em modernização das plantas existentes e em abertura de novas unidades de produção. O resultado foi um expressivo aumento de produção, produtividade e consumo de autoveículos, que alçaram o Brasil à 7ª posição no ranking de países produtores e à 4ª no de vendas domésticas, consolidando sua condição de plataforma regional de fabricação para o mercado sul-americano. Ademais, algumas das subsidiárias brasileiras chegaram a um nível de domínio da tecnologia, que as habilitaram ao desenvolvimento autônomo de novos autoveículos.

  10. [Reduction of automobile traffic: urgent health promotion policy].

    Science.gov (United States)

    Tapia Granados, J A

    1998-03-01

    During the last few decades, traffic injuries have become one of the leading causes of death and disability in the world. In urban areas, traffic congestion, noise, and emissions from motor vehicles produce subjective disturbances and detectable pathological effects. More than one billion people are exposed to harmful levels of environmental pollution. Because its combustion engine generates carbon dioxide (CO2), the automobile is one of the chief sources of the gases that are causing the greenhouse effect. The latter has already caused a rise in the average ambient temperature, and over the next decades it will predictable cause significant climatic changes whose consequences, though uncertain, are likely to be harmful and possibly catastrophic. Aside from the greenhouse effect, the relentless growth of parking zones, traffic, and the roadway infrastructure in urban and rural areas is currently one of the leading causes of environmental degradation. Urban development, which is nearly always "planned" around traffic instead of people, leads to a significant deterioration in the quality of life, while it also destroys the social fabric. Unlike the private automobile, public transportation, bicycles, and walking help reduce pollution, congestion, and traffic volume, as well as the morbidity and mortality resulting from injuries and ailments related to pollution. Non-automobile transportation also encourages physical activity--with its positive effect on general health--and helps reduce the greenhouse effect. The drop in traffic volume and the increased use of alternate means of transportation are thus an integrated health promotion policy which should become an inherent part of the movement for the promotion of healthy cities and of transportation policies and economic policy in general.

  11. Individualized solutions to environmental problems: a case of automobile pollution

    1999-09-01

    Air pollution associated with motor vehicle use is one of the prime indicators of the tension between consumerism and the environment. The use of private automobiles seems so convenient, whereas the alternatives are off-putting enough to make significant changes in personal transportation behaviour well-nigh impossible. At the same time, combating the air pollution associated with extensive use of cars has become one of the major policy objectives for cities around the world. Available policy alternatives can be divided into two categories: (1) incentives, such as improved public transportation, and (2) disincentives, such as environmental tax on gasoline. This paper attempt to directly assess links between these two alternatives, associated attitudes towards them, the level of public support for command and control (i.e. regulatory) policy approaches as well as for economic incentive/disincentive policies. Answers are sought and findings discussed relative to the link between opinions about the environment and support for different types of environmental policies, the usefulness of a rational choice perspective in explaining support for environmental policy alternatives, the role that partisan political attachments play in support of environmental policy approaches, and the roles played by environmental activism, knowledge, and action in shaping support for environmental policy alternatives. Overall results indicate that while most people living in urban environments support the ideas of environmental protection and would be willing to incur costs to confront the problem, exposure to air pollution plays an inconsequential (actually nearly non-existent) role in support of automobile-related environmental problems. Automobile users act like 'free-riders' i.e. they tend to support policies that socialize the cost of solutions rather than policies that attempt to pass the cost of pollution directly on to individual car owners.

    2015-02-01

    Full Text Available Introduction: traffic accidents are one of the main causes of death and disability, with motorcyclists representing the great majority of both the victims and the perpetrators. Objective: this work studied the characteristics of motorcyclists injured in accidents involving motorcycles and automobiles. Method: this study sought to interview 100 motorcyclists who had been injured in collisions between motorcycles and automobiles, and who were undergoing emergency hospital treatment in the region of Belo Horizonte, Brazil. The questionnaires included demographic information (age, gender, skin color, education level, profession and questions about years of licensed driving practice, how often they would drive an automobile, how long they had had a motorcycle driver’s license, how often they would ride a motorcycle, the number of prior accidents involving a car, and the number of prior accidents not involving a car. Results: of the 100 consecutive accidents studied, 91 occurred with men and 9 with women, aged between 16 and 79 (m = 29 ± 11 years. Regarding their reason for using a motorcycle, 83% reported using it for transport, 7% for work, and 10% for leisure. Most of these accident victims had secondary or higher education (47%. Of the motorcyclists who held a car driver’s license, 68.3% drove the vehicle daily or weekly and held the license for more than one year. Sixty-seven percent of the accident victims used a motorcycle daily and had a motorcycle driver’s license for at least one year. Conclusion: among the motorcyclists injured, most were men aged 20 years or older, with complete secondary education, and experienced in driving both motorcycles and cars, indicating that recklessness while driving the motorcycle is the main cause of traffic accidents.

    The article presents updated epidemiological information on specific features and causes of high automobile traumatism in Russia and abroad for the last 5 years. The number of road accidents and road accident fatalities now not only present a great social-medical problem in Russia but also a problem of national security as road accident mortality is far ahead of the developed countries and showed no trend to lowering. This threatening situation is caused by out-of-date transport infrastructure, social factors, old cars without modern safety systems, absence of special emergency medical care for road accident victims. The experience of foreign countries on reducing road traumatism is analysed.

    Full Text Available Asbestos has been used for so long as automobile brake lining material because of its good physical and chemical properties. However, due to the health hazard associated with its handling, it has lost favour and several alternative materials are being increasingly used. Asbestos-free brake lining was developed in this work using pulverized cow hooves along with epoxy resin, barium sulphate, graphite and aluminium oxide. This was with a view to exploiting the characteristics of cow hooves, which are largely discarded as waste materials to replace asbestos which has been found to be carcinogenic. Samples of brake linings were produced using compressive moulding in which the physical and mechanical properties of the samples were studied. The results obtained showed that proper bonding was achieved as the percentage by weight of epoxy resin increased and percentage by weight of pulverized cow hooves decreased. The hardness, compressive strength, coefficient of friction, water and oil absorption, relative density and wear rate of the brake linings were determined and compared with existing brake lining properties. The result indicates that pulverized cow hooves can be used as brake lining material for automobiles.

A primeira aborda a problemática moderna em torno da relação entre conhecimento científico e organização social, destacando, de um lado, as perspectivas críticas que investigam os condicionantes sociais e históricos dos padrões cognitivos dominantes e, de outro, as políticas científicas e tecnológicas que propõem e promovem a redefinição da atividade científica em termos de desempenho econômico. À luz desse cenário, a segunda seção situa a criação da Rede de Tecnologia Social no Brasil para discutir, a partir da definição de tecnologia social de Renato Dagnino, algumas dificuldades e certos limites das possibilidades cognitivas e políticas da concepção e da prática de uma "tecnologia social". A exposição enfatiza a natureza social dos obstáculos que se opõem a essas possibilidades alternativas.

Este texto se organiza em quatro tópicos principais: o primeiro introduz o conceito de tecnologia educacional simbólica; o segundo, o conceito de metacognição; o terceiro procura unir os dois primeiros ao discutir o conceito e o papel dos símbolos na perspectiva fenomenológica; o quarto, mais operacional, exemplifica como a metacognição faz uso de símbolos e cifras para gerenciar o processo de aprendizagem, enquadrando-se, assim, no conceito de Tecnologia Educacional Simbólica.

  3. Life cycle models of conventional and alternative-fueled automobiles

    Science.gov (United States)

    Maclean, Heather Louise

    This thesis reports life cycle inventories of internal combustion engine automobiles with feasible near term fuel/engine combinations. These combinations include unleaded gasoline, California Phase 2 Reformulated Gasoline, alcohol and gasoline blends (85 percent methanol or ethanol combined with 15 percent gasoline), and compressed natural gas in spark ignition direct and indirect injection engines. Additionally, I consider neat methanol and neat ethanol in spark ignition direct injection engines and diesel fuel in compression ignition direct and indirect injection engines. I investigate the potential of the above options to have a lower environmental impact than conventional gasoline-fueled automobiles, while still retaining comparable pricing and consumer benefits. More broadly, the objective is to assess whether the use of any of the alternative systems will help to lead to the goal of a more sustainable personal transportation system. The principal tool is the Economic Input-Output Life Cycle Analysis model which includes inventories of economic data, environmental discharges, and resource use. I develop a life cycle assessment framework to assemble the array of data generated by the model into three aggregate assessment parameters; economics, externalities, and vehicle attributes. The first step is to develop a set of 'comparable cars' with the alternative fuel/engine combinations, based on characteristics of a conventional 1998 gasoline-fueled Ford Taurus sedan, the baseline vehicle for the analyses. I calculate the assessment parameters assuming that these comparable cars can attain the potential thermal efficiencies estimated by experts for each fuel/engine combination. To a first approximation, there are no significant differences in the assessment parameters for the vehicle manufacture, service, fixed costs, and the end-of-life for any of the options. However, there are differences in the vehicle operation life cycle components and the state of technology

Para o desenvolvimento do trabalho, foi proposta uma pesquisa de abordagem qualitativa, com objetivos exploratórios e descritivos através de um estudo de campo, realizado em uma escola da rede municipal de Ilhéus. Para isso, como recurso metodológico, utilizamos técnicas de coletas de dados: observação sistemática da escola e entrevistas semiestruturadas com os professores e gestores. Os resultados nos mostraram inúmeros desafios para que essas práticas se concretizem. Na escola, foram encontradas as seguintes tecnologias de comunicação: televisão, computador, notebook, máquina fotográfica digital, data show e som. Além disso, apesar de a escola pesquisada possuir alguns recursos tecnológicos disponíveis, ainda há a burocracia para se utilizar tais aparatos. Concluiu-se, portanto, que o não acesso e a inviabilização às ferramentas de tecnologia de comunicação por parte de professores e alunos são causas diretas de um problema mais amplo (associado às deficiências na formação de usuários destas tecnologias e que compromete a eficiência do processo de ensino-aprendizagem: o problema da exclusão digital.

    The energy demand of climate-control instruments is an increasingly important focus of study in the automobile industry. The ratio of the energy demand for the engine as opposed to that of other car components will greatly change in the future. Especially for electrical vehicles the auxiliary energy use is very critical because of the limited battery capacity. Thus, the aim of this research project is to investigate means of more efficiently using the available energy by maintaining comfort criteria for all passengers. To realize this, a simulation model of a car interior cabin is being developed with which conclusions can be drawn, under the given boundary conditions, about the air circulation and -states as well as about the resulting energy demand to evaluate the efficiency and the thermal comfort.

    Wastes with residual heating value, according to the trend of the world legislation, could be thermally reused. The present study is conducted to verify the possibility of thermal valorisation of a waste, denominated fluff, by injection in blast furnace. The fluff, arising from the automobile shredder operations, is a waste characterised by a high organic matrix and is potentially dangerous due to the heavy metals, oils filter and halogenated plastics content. The first step of the work is the chemical, physical and toxicological characterisation of this material. Then the fluff injection in a blast furnace tuyere is theoretically analysed with a mathematical model. Finally, experimental trials are conducted in a pilot plant, simulating the most important part of the blast furnace: the raceway, in order to analyse process and industrial aspects. In view of an industrial application a first economical evaluation is carried out on the basis of model and experimental results.

    1994-01-01

    Transportation network capacity variations arising from accidents, roadway maintenance activity, and special events as well as fluctuations in commuters' travel demands complicate traffic management. Artificial intelligence concepts and expert systems can be useful in framing policies for incident detection, congestion anticipation, and optimal traffic management. This paper examines the applicability of intelligent route guidance and control as decision aids for traffic management. Basic requirements for managing traffic are reviewed, concepts for studying traffic flow are introduced, and mathematical models for modeling traffic flow are examined. Measures for quantifying transportation network performance levels are chosen, and surveillance and control strategies are evaluated. It can be concluded that automated decision support holds great promise for aiding the efficient flow of automobile traffic over limited-access roadways, bridges, and tunnels.

    1979-01-01

    A thermal energy storage (TES) system developed for use with the Stirling engine as an automotive power system has gravimetric and volumetric storage densities which are competitive with electric battery storage systems, meets all operational requirements for a practical vehicle, and can be packaged in compact sized automobiles with minimum impact on passenger and freight volume. The TES/Stirling system is the only storage approach for direct use of combustion heat from fuel sources not suitable for direct transport and use on the vehicle. The particular concept described is also useful for a dual mode TES/liquid fuel system in which the TES (recharged from an external energy source) is used for short duration trips (approximately 10 miles or less) and liquid fuel carried on board the vehicle used for long duration trips. The dual mode approach offers the potential of 50 percent savings in the consumption of premium liquid fuels for automotive propulsion in the United States.

    Full Text Available An automotive air-conditioning system based on absorption refrigeration cycle has been simulated. This waste heat driven vapor absorption refrigeration system is one alternate to the currently used vapour compression refrigeration system for automotive air-conditioning. Performance analysis of vapor absorption refrigeration system has been done by developing a steady-state simulation model to find the limitation of the proposed system. The water-lithium bromide pair is used as a working mixture for its favorable thermodynamic and transport properties compared to the conventional refrigerants utilized in vapor compression refrigeration applications. The pump power required for the proposed vapor absorption refrigeration system was found lesser than the power required to operate the compressor used in the conventional vapor compression refrigeration system. A possible arrangement of the absorption system for automobile application is proposed.

    N-alkyl-2-pyrrolidones are important organic solvents for varnishes in industry. This study investigates exposure to N-ethyl-2-pyrrolidone (NEP) in varnishing of hard plastic components in an automobile plant. Two specific biomarkers of exposure, 5-hydroxy-N-ethyl-2-pyrrolidone (5-HNEP) and 2-hydroxy-N-ethylsuccinimide (2-HESI), were analyzed in urine samples of 14 workers. For this purpose, pre-shift, post-shift and next day pre-shift urine samples were collected midweek. Twelve workers performed regular work tasks (loading, wiping and packing), whereas two workers performed special work tasks including cleaning the sprayer system with organic solvents containing N-alkyl-2-pyrrolidones. Spot urine samples of nine non-exposed persons of the same plant served as controls. Median post-shift urinary levels of workers with regular work tasks (5-HNEP: 0.15 mg/L; 2-HESI: 0.19 mg/L) were ∼5-fold higher compared to the controls (0.03 mg/L each). Continuously increasing metabolite levels, from pre-shift via post-shift to pre-shift samples of the following day, were observed in particular for the two workers with the special working tasks. Maximum levels were 31.01 mg/L (5-HNEP) and 8.45 mg/L (2-HESI). No clear trend was evident for workers with regular working tasks. In summary, we were able to show that workers can be exposed to NEP during varnishing tasks in the automobile industry. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

    2005-11-01

    The automobile manufacturing industry plays a very important role in a country's economy. The importance of automobile manufacturing industry lies in its sheer size and complexity in terms of the direct and indirect influence it commands across many other industries. While millions of people are employed in the automobile manufacturing industry, it is estimated that more than two and half times that number are employed in the auxiliary companies that supply parts to the automobile manufacturing companies. The auxiliary companies represent a group of businesses of various sizes, types, and geographical locations, producing a vast variety of products ranging from the very simple to the extremely intricate. In this study, the current environmental practices of management in the core Spanish auxiliary companies that do business with the automobile manufacturing industry (and thus form a large part of the automobile manufacturing industry's supply chain) are investigated. We show that while automobile manufacturing companies are under scrutiny to become more and more environmentally friendly, not only at their manufacturing stage but also at their products' useful and EOL stages, there appears to be no such burden on the auxiliary companies. Our conclusion is based on an elaborate survey conducted during the fall of 2004 of Spanish auxiliary companies with questions about the characteristics, environmental practices and reverse logistics related activities carried out by the companies.

  1. A bivariate model for analyzing recurrent multi-type automobile failures

    Science.gov (United States)

    Sunethra, A. A.; Sooriyarachchi, M. R.

    2017-09-01

    The failure mechanism in an automobile can be defined as a system of multi-type recurrent failures where failures can occur due to various multi-type failure modes and these failures are repetitive such that more than one failure can occur from each failure mode. In analysing such automobile failures, both the time and type of the failure serve as response variables. However, these two response variables are highly correlated with each other since the timing of failures has an association with the mode of the failure. When there are more than one correlated response variables, the fitting of a multivariate model is more preferable than separate univariate models. Therefore, a bivariate model of time and type of failure becomes appealing for such automobile failure data. When there are multiple failure observations pertaining to a single automobile, such data cannot be treated as independent data because failure instances of a single automobile are correlated with each other while failures among different automobiles can be treated as independent. Therefore, this study proposes a bivariate model consisting time and type of failure as responses adjusted for correlated data. The proposed model was formulated following the approaches of shared parameter models and random effects models for joining the responses and for representing the correlated data respectively. The proposed model is applied to a sample of automobile failures with three types of failure modes and up to five failure recurrences. The parametric distributions that were suitable for the two responses of time to failure and type of failure were Weibull distribution and multinomial distribution respectively. The proposed bivariate model was programmed in SAS Procedure Proc NLMIXED by user programming appropriate likelihood functions. The performance of the bivariate model was compared with separate univariate models fitted for the two responses and it was identified that better performance is secured by

Para este estudo, baseamo-nos nas teorias do discurso, na psicanálise e na filosofia derrideana, cuja tarefa é desconstruir o edifício logocêntrico da cultura ocidental. Depois de analisar 50 redações de professores, foi possível observar que coabitam crenças que remetem ao professor missionário e idealista e a mitificação das novas tecnologias como a solução para os problemas de método e de motivação. Chocam-se, assim, resistências ao passado e resistências às novas tecnologias, que perturbam a garantia do saber e, portanto, do poder do professor, enfatizando o saber do aluno.

    Full Text Available Resumo:As tecnologias sociais (TS, como ações que visam a melhorar a qualidade de vida de grupos sociais diversos e que se encontram à margem do mercado ou do sistema econômico, têm por objetivo um novo modelo de desenvolvimento não predatório. Diante da ideia de melhoria da qualidade de vida, essas tecnologias acabam obtendo uma difusão sem limites, colaborando mais para a manutenção do sistema que para a solução definitiva dos problemas sociais. Tendo isso em vista, o objetivo principal deste ensaio teórico é discutir o quanto, muitas vezes, as TS acabam virando panaceia e instrumento das relações de poder, funcionando na justificação e intensificação de novas formas de dominação nas sociedades contemporâneas. Com o intuito de refletir sobre a difusão dessas tecnologias, inicialmente, surgiu a necessidade de aprofundar o entendimento sobre o que são as TS. Em seguida, o intuito foi explorar a visão de Michel Foucault sobre as biopolíticas e o biopoder, e entremear, nessa discussão, as TS.

    Full Text Available Em muitos debates sobre as relações entre ciência e sociedade, em particular quanto à aceitação das tecnologias ou à percepção de seus riscos, existe uma hipótese subjacente: a de que a ignorância gera medo, e o medo gera desconfiança ou hostilidade contra a ciência e a tecnologia. Neste artigo mostramos que essa hipótese é questionável. Com base numa recente enquete nacional, apontamos que atitudes otimistas sobre ciência e tecnologia não dependem do nível escolar ou da informação declarada ou acessada pelas pessoas sobre o tema. Indivíduos com escassa informação possuem, em geral, atitudes positivas. Pessoas com maior escolaridade e acesso à informação possuem atitudes diversificadas, otimistas sobre alguns aspectos, porém mais críticas sobre outros.

    Aerosol and soil samples were collected from places near the main roads in Khartoum area. The samples were analyzed by energy Dispersive x-ray fluorescence (EDXRF) technique, to study the lead (Pb) concentration in air and soil near roadsides due to automobile emissions. The aim of the study was also to make a comparison with the results of previous measurements made in the same field (Ahmed, 1983) . Thee aerosol samples were taken from three sites in Khartoum area. Tuti island taken as a control area, central Khartoum as a commercial area and south of Khartoum as a residential area. Soil samples were taken from a place near Al Gurashi Park and another near Abu Hamama traffic junction in Khartoum area. The data obtained of (Pb) concentrations in the roadside air were statistically analyzed. Comparisons were made between the concentrations at the various times of the day and correlation were made with meteorological parameters. The (Pb) concentrations in the roadside soil were observed to be inversely proportional to the distance from the road and the depth from the layer of the earth.

    Today’s automobiles depend upon mechanical systems that are crucial for aiding in the movement and safety features of the vehicle. Various safety systems such as Antilock Braking System (ABS) and passenger restraint systems have been developed to ensure that in the event of a collision be it head on or any other type, the safety of the passenger is ensured. On the other side, manufacturers also want their customers to have a good experience while driving and thus aim to improve the handling and the drivability of the vehicle. Electronics systems such as Cruise Control and active suspension systems are designed to ensure passenger comfort. Finally, to ensure optimum and safe driving the various components of a vehicle must be manufactured using the latest state of the art processes and must be tested and inspected with utmost care so that any defective component can be prevented from being sent out right at the beginning of the supply chain. Therefore, processes which can improve the lifetime of their respective components are in high demand and much research and development is done on these processes. With a solid base research conducted, these processes can be used in a much more versatile manner for different components, made up of different materials and under different input conditions. This will help increase the profitability of the process and also upgrade its value to the industry.

  10. Optimization of Thermoelectric Components for Automobile Waste Heat Recovery Systems

    2015-10-01

    For a typical spark ignition engine approximately 40% of available thermal energy is lost as hot exhaust gas. To improve fuel economy, researchers are currently evaluating technology which exploits exhaust stream thermal power by use of thermoelectric generators (TEGs) that operate on the basis of the Seebeck effect. A 5% improvement in fuel economy, achieved by use of TEG output power, is a stated objective for light-duty trucks and personal automobiles. System modeling of thermoelectric (TE) components requires solution of coupled thermal and electric fluxes through the n and p-type semiconductor legs, given appropriate thermal boundary conditions at the junctions. Such applications have large thermal gradients along the semiconductor legs, and material properties are highly dependent on spatially varying temperature profiles. In this work, one-dimensional heat flux and temperature variations across thermoelectric legs were solved by using an iterative numerical approach to optimize both TE module and TEG designs. Design traits were investigated by assuming use of skutterudite as a thermoelectric material with potential for automotive applications in which exhaust gas and heat exchanger temperatures typically vary from 100°C to over 600°C. Dependence of leg efficiency, thermal fluxes and electric power generation on leg geometry, fill fractions, electric current, thermal boundary conditions, etc., were studied in detail. Optimum leg geometries were computed for a variety of automotive exhaust conditions.

  11. On the baseline evolution of automobile fuel economy in Europe

    'Business as usual' scenarios in long-term energy forecasts are crucial for scenario-based policy analyses. This article focuses on fuel economy of passenger cars and light trucks, a long-disputed issue with serious implications for worldwide energy use and CO 2 emissions. The current status in Europe is explained and future developments are analysed with the aid of historical data of the last three decades from the United States and Europe. As a result of this analysis, fuel economy values are proposed for use as assumptions in baseline energy/transport scenarios in the 15 'old' European Union Member States. Proposed values are given for new gasoline and diesel cars and for the years 2010, 2020 and 2030. The increasing discrepancy between vehicle fuel consumption measured under test conditions and that in the real world is also considered. One main conclusion is that the European Commission's voluntary agreement with the automobile industry should not be assumed to fully achieve its target under baseline conditions, nor should it be regarded as a major stimulus for autonomous vehicle efficiency improvements after 2010. A second conclusion is that three very recent studies enjoying authority across the EU tend to be overly optimistic as regards the technical progress for conventional and alternative vehicle propulsion technologies under 'business as usual' conditions

    Sedentary lifestyles contribute to premature death and health inequalities. Researchers have studied personal and community-level determinants of inactivity but few have analyzed corporate influences. To reframe the public health debate on inactivity and open new doors for public sector intervention, we conducted a scoping review of evidence from several disciplines to describe how the business and political practices of the automobile, construction, and entertainment sectors have encouraged sedentary lifestyles. In the last 50 years, these industries have found it profitable to produce motor vehicles, housing, and entertainment, which intentionally or unintentionally discourage physical activity. Ceding primary authority for policy decisions in these sectors to the market-based economy has enabled the growth of powerful lobbies that encourage and maintain sedentary lifestyles. To counteract these influences, public health and civil society need to confront more upstream economic and social determinants of sedentary lifestyles. Building on evidence from efforts to change harmful tobacco, alcohol and food industry practices, we propose the creation of research and policy agendas that contribute to public health practice that can modify corporate practices that contribute to physical, social and political environments that discourage physical activity.

  13. Weight Penalty Incurred in Thermoelectric Recovery of Automobile Exhaust Heat

    2011-05-01

    Thermoelectric recovery of automobile waste exhaust heat has been identified as having potential for reducing fuel consumption and environmentally unfriendly emissions. Around 35% of combustion energy is discharged as heat through the exhaust system, at temperatures which depend upon the engine's operation and range from 800°C to 900°C at the outlet port to less than 50°C at the tail-pipe. Beneficial reduction in fuel consumption of 5% to 10% is widely quoted in the literature. However, comparison between claims is difficult due to nonuniformity of driving conditions. In this paper the available waste exhaust heat energy produced by a 1.5 L family car when undergoing the new European drive cycle was measured and the potential thermoelectric output estimated. The work required to power the vehicle through the drive cycle was also determined and used to evaluate key parameters. This enabled an estimate to be made of the engine efficiency and additional work required by the engine to meet the load of a thermoelectric generating system. It is concluded that incorporating a thermoelectric generator would attract a penalty of around 12 W/kg. Employing thermoelectric modules fabricated from low-density material such as magnesium silicide would considerably reduce the generator weight penalty.

    The environmental impact of the automobile and its components is of growing importance not only in public debates but also in the complex decision making process regarding future car concepts. To calculate the environmental compatibility of car components BMW had developed various quantifying instruments and a holistic Life-Cycle Analysis (LCA) approach. The development phase significantly affects the entire life-cycle of a product. Suitable design criteria, recycling requirements and in-house standards have therefore been developed and established. They enable the designer to handle the more and more complex conflicts of technical, economic and ecological objectives during the development process with special view to the customer, i.e. the market. (orig.) [Deutsch] Zur nachhaltigen Verbesserung der Umweltvertraeglichkeit von Automobilen und Bauteilen hat BMW quantitative Instrumente entwickelt: Den `Anforderungskatalog Gesamtfahrzeug`, die BMW-Recycling-Norm, die Demontageanalyse von Automobilen und die lebenszyklusbezogene Bauteil-Bilanzierung. Sie sollen es dem Konstrukteur in der Entwicklungsphase praxisgerecht ermoeglichen, verschiedene Bauteilvarianten oekologisch zu bewerten. Nur so koennen die weiter zunehmenden komplexen Zielkonflike in der Automobilentwicklung, die sowohl technisch-wirtschaftlicher als auch oekonomisch-oekologischer und teilweise gesellschaftspolitischer Natur sind, in Zukunft beherrscht und damit den Markt- und Kundenanforderungen gerecht werden.

    This presentation outlined the organization of the auto industry, with reference to the tier levels of the supply chain. Automakers or original equipment manufacturers (OEMs) such as Daimler Chrysler, Ford Motor Company, General Motors, Honda, Toyota and Nissan are at the top of the structure, followed by tier 1 suppliers, tier 2 suppliers and tier 3 companies. In recent years, the auto industry has experienced an explosion of new products, building more vehicle types with fewer plants. It was shown that since 1990, auto parts supply companies have consolidated. Currently, Canada's automotive sector is the world's eighth largest producer of motor vehicles. The 6 OEMs operate 12 active assembly plants in Canada plus several engine and drivetrain part plants and support facilities. More than 500,000 Canadians work directly and indirectly in the auto industry, which generates 12 to 13 per cent of Canada's gross domestic product. It was noted that automotive design is driven, in large part, by energy prices. The industry strives to make vehicles safer; improve fuel economy and reduce environmental impacts; and, re-tool the business model by improving supplier relationship and making assembly more efficient and safer in order to control cost and improve profitability. The challenges for the new automobile include new powertrains that use alternate fuels or have electric drive and control systems; new structures and materials; and, new systems and capabilities. The future of fuel cell powertrains was also discussed with reference to prototypes or products already in the market. tabs., figs.

    Reduced pressure pain thresholds (PPTs) have been reported in occupational groups with symptoms of upper extremity musculoskeletal disorders (UEMSDs). The purpose of this study was to determine whether automobile manufacturing workers (n=460) with signs and symptoms of UEMSDs had reduced PPTs (greater sensitivity to pain through pressure applied to the skin) when compared with unaffected members of the cohort, which served as the reference group. The association of PPTs with symptom severity and localization of PE findings was investigated, as was the hypothesis that reduced thresholds would be found on the affected side in those with unilateral physical examination (PE) findings. PPTs were measured during the workday at 12 upper extremity sites. A PE for signs of UEMSDs and symptom questionnaire was administered. After comparison of potential covariates using t tests, linear regression multivariable models were constructed with the average of 12 sites (avgPPT) as the outcome. Subjects with PE findings and/or symptoms had a statistically significant lower avgPPT than non-cases. AvgPPT was reduced in those with more widespread PE findings and in those with greater symptom severity (test for trend, P

    In any industry, heating, cooling and compressed air the costliest part, which affects the production cost of any product. There are three types of indirect heat requirement or the requirement of heat can be divided in the three main categories. (1) low temp. 40 - 60 Deg. (2) Medium temp. 80 - 150 deg. (3) High Temp applications - above 150. Solar Flat Collectors have been proven for the use of solar energy for medium temp. application in hotels, boiler feed water preheating, dairy for pasteurization and some other indirect heating applications. There is another neglected area of application of Solar Flat Plate collector is heat treatment for powder coating plants where heat requirement is bet 50 Deg C - 70 Deg C. In any automobile industry the aesthetic or look of the vehicle place a very important role as far as the sale is concern (after the mechanical performance). The aesthetic means the body and colour of the vehicle. To get a long lasting good quality color, the powder coating procedure plays a major role. Before powder coating there is requirement of different chemical treatment for the removal of rust, grease and other cleaning of the specific sheet metal body parts. The time duration and chemical composition is depends on the selection of body material. A proven method of a chemical treatment is seven / eight tank process. The common system of heating chemicals is by way of electrical heaters, by diesel or other fuel fired boilers. This increases the cost of heat treatment process due the high cost of electricity (for industries rate of electricity is 1.5 to 2 times than the domestic rate) or oils. This can be replaced by Solar water heating system which can efficiently generate the temp of liquid upto 85 Deg C. (orig.)

    Polybrominated diphenyl ethers (PBDEs), a class of brominated flame retardants, have been widely used in many applications in industry such as automobiles, textiles, and electronics. This study focused on a quantitative substance flow analysis (SFA) of PBDEs in automobiles in order to identify their flow by life cycle and treatment pathways of PBDEs-containing materials in end-of-life vehicles (ELVs) in Korea. In addition, this study has estimated environmental releases of PBDEs in automobiles by life cycle in Korea. During this study, PBDEs were analyzed for the samples collected from several ELVs treatment facilities using X-ray fluorescence and gas chromatography/mass spectrometry (GC/MS) methods. The system boundary for SFA of PBDEs ranged from manufacturing/trade to disposal stage of automobiles by life cycle. Based on the result of the SFA, it was found that the amount of PBDEs in automobiles were the highest in use stage (7748ton/year), followed by production stage (1743ton/year) in 2014. In disposal stage, automobile shredded residues (ASR) and seat fabrics were the main components with relatively high levels of PBDEs in ELVs. The major treatment methods of such components included incineration (84%), energy recovery (9%), and landfilling (6%). This research indicates that PBDEs were emitted the highest amount from interior components during the use stage of automobiles, followed by recycling processes such as dismantling and shredding. This study suggests that PBDEs in ASR and seat fabrics should be properly managed to prevent the widespread dispersion in the environment. Copyright © 2016 Elsevier B.V. All rights reserved.

    Full Text Available Resumo Diante de ambiente dinâmico, como é o caso do setor automobilístico, alvo deste estudo, as organizações são desafiadas a estabelecer flexibilidade estratégica, conquistada por meio de inovações, que exigem a exploração e explotação do conhecimento. Estudos prévios apontam que a combinação de exploração e explotação do conhecimento é a estratégia ideal para inovação, pois a organização acessará novas tecnologias por meio da exploração de novos conhecimentos e refinará e aperfeiçoará a tecnologia dominante por meio da explotação do conhecimento primário. Grande parte dos estudos sobre o tema foca suas contribuições em analisar o impacto das iniciativas de gestão do conhecimento e da exploração e explotação do conhecimento sobre o desempenho inovativo e financeiro da firma; entretanto, percebem-se poucos estudos que investigam os fatores organizacionais que sustentam os processos de exploração e explotação do conhecimento. Os resultados da pesquisa mostram que os processos de exploração e explotação do conhecimento são impactados de forma distinta por cinco fatores contextuais, considerados nesta pesquisa: gestão de recursos humanos, liderança colaborativa, cultura de aprendizagem, autonomia e sistemas de tecnologia de informação (TI. Enquanto exploração é mais impactada por cultura de aprendizagem, autonomia e sistemas de TI, explotação está mais relacionada com liderança colaborativa e cultura de aprendizagem.

    Full Text Available La agricultura de bajo impacto ambiental demanda nuevos pesticidas que deben ajustarse a las exigentes normativas internacionales. Parte de la búsqueda de nuevos productos bio-racionales se desarrolla por fuera del marco de la síntesis orgánica, explorando diferentes sustancias de origen natural como extractos vegetales, aceites insecticidas e insecticidas inorgánicos. Los polvos insecticidas representan el grupo más antiguo de sustancias utilizadas por el hombre para el control de plagas, cuya eficacia se basa principalmente en fenómenos físicos. Con el advenimiento de los insecticidas de síntesis, los polvos insecticidas fueron relegados por casi cinco décadas a la función de carriers de principios activos dentro de los insecticidas formulados. Con el desarrollo del caolín hidrófobo en la década de los 90 ́, los polvos inorgánicos resurgieron como insecticidas “per se”, y, recientemente, a partir del descubrimiento de los nanoinsecticidas, afloran nuevas alternativas para expandir el espectro de aplicaciones de los polvos inorgánicos. El desarrollo y registro de nuevos productos a partir de nanomateriales manufacturados se basa en el paradigma “lo mismo pero diferente”, ya que éstos difieren de las sustancias con idéntica estructura y composición química respecto de algunas propiedades como reactividad, área especifica, efectos cuánticos, carga eléctrica, etc. Estas sustancias con nuevas propiedades también se destacan como herramientas muy prometedoras para la protección de cultivos y la producción de alimentos y abren nuevas fronteras para el manejo de plagas con nanoinsecticidas. La alúmina nanoestructurada exhibe varias de las propiedades del insecticida ideal, ya que se trata de un producto natural desde el punto de vista químico, no reactivo, económico, con reducidas probabilidades de provocar resistencia en los insectos y su eficacia es mayor que la de otros polvos insecticidas como el caolín o la

It also evaluates whether the frequently-held assumption that increasing prohibition or taxes on trade leads to a rise in contraband holds true for Colombia. If it does hold true, the article also attempts to establish whether or not there was greater contraband in prohibited or highly-taxes products.

    2008-09-12

    As one of the measures to improve the environment in an automobile, malodor caused by the automobile air-conditioning system evaporator was evaluated and analyzed using laboratory-scale test cooling bench. The odor was simulated with an evaporator test cooling bench equipped with an airflow controller, air temperature and relative humidity controller. To simulate the same odor characteristics that occur from automobiles, one previously used automobile air conditioner evaporator associated with unpleasant odors was selected. The odor was evaluated by trained panels and collected with aluminum polyester bags. Collected samples were analyzed by thermal desorption into a cryotrap and subsequent gas chromatographic separation, followed by simultaneous olfactometry, flame ionization detector and identified by atomic emission detection and mass spectrometry. Compounds such as alcohols, aldehydes, and organic acids were identified as responsible odor-active compounds. Gas chromatography/flame ionization detection/olfactometry combined sensory method with instrumental analysis was very effective as an odor evaluation method in an automobile air-conditioning system evaporator.

    Environmental sustainability and green environmental issues have an increasing popularity among researchers and supply chain practitioners. An attempt has been made to identify and empirically analyze green supply chain management (GSCM) practices in Indian automobile industry. Six main GSCM practices (having 37 sub practices) and four expected performance outcomes (having 16 performances) have been identified by implementing GSCM practices from literature review. Questionnaire based survey has been made to validate these practices and performance outcomes. 123 complete questionnaires were collected from Indian automobile organizations and used for empirical analysis of GSCM practices in Indian automobile industry. Descriptive statistics have been used to know current implementation status of GSCM practices in Indian automobile industry and multiple regression analysis has been carried out to know the impact on expected organizational performance outcomes by current GSCM practices adopted by Indian automobile industry. The results of study suggested that environmental, economic, social and operational performances improve with the implementation of GSCM practices. This paper may play an important role to understand various GSCM implementation issues and help practicing managers to improve their performances in the supply chain.

    Asian countries are now attracting attention of automobile manufacturers of the world for their capabilities of buying, producing, and assembling of automobiles, and producing and supplying of parts, which means that the Asian market is now exposed to globalization. As for the automobile and part manufacturers of Japan, in the presence of economic depression lingering in Asia affecting motorization and rapid changes in the circumstances Japan`s automobile industry finds itself under, are pressed to work out new strategies as a member of the Asian community. A panel discussion of the same name as the subject held in 1997 won favor as a fine initiative to suitably cope with the difficult situation. Useful suggestions and proposals were made concerning the panel discussion, calling the event a new type of round-table talks well responding to the rapid changes in the world economy since 1997, by learned and experienced people, the government offices concerned, staffers of manufacturers in charge of overseas marketing, and international information analysts. They related to the current state and tasks of automobile manufacturing in Asia, trends of regulations and standardization, rolls of technical assistance and the Society of Automotive Engineers of Japan, Ltd., expressed from a wide angle covering various problems relative to environmental protection, safety, etc. (NEDO)

  5. As tecnologias da informação e a exclusão digital

    Directory of Open Access Journals (Sweden)

    Clarinda Rodrigues Lucas

    Full Text Available As tecnologias da informação e a nova economia baseada no conhecimento provocam debates concernentes às dimensões sociais, políticas e culturais conseqüentes ao seu uso, consolidadas no termo exclusão digital, que tem aparecido com freqüência na mídia, na Internet e em alguns artigos da área da Ciência da Informação, referindo-se ao não uso destes recursos tecnológicos. Por exclusão digital ou infoexclusão, entende-se a diferença socioeconômica entre indivíduos, famílias, empresas e regiões geográficas, decorrentes da desigualdade quanto ao acesso e uso das tecnologias da informação, representada pela Internet. No âmbito das bibliotecas, consideradas instituições sociais que podem ter um sentido de comunidade, isto é, um espaço de conexão entre recursos de informação com as comunidades que as utilizam, o objetivo de inclusão social estaria concretizado em políticas de informação para a cidadania, em oposição à exclusão socioeconômica. Neste texto são analisados os aspectos ligados às questões relativas ao uso e às políticas que cercam a tecnologia da informação e lhe atribuem conteúdo.

    We examine the life cycles of gasoline, diesel, compressed natural gas (CNG), and ethanol (C2H5OH)-fueled internal combustion engine (ICE) automobiles. Port and direct injection and spark and compression ignition engines are examined. We investigate diesel fuel from both petroleum and biosources as well as C2H5OH from corn, herbaceous bio-mass, and woody biomass. The baseline vehicle is a gasoline-fueled 1998 Ford Taurus. We optimize the other fuel/powertrain combinations for each specific fuel as a part of making the vehicles comparable to the baseline in terms of range, emissions level, and vehicle lifetime. Life-cycle calculations are done using the economic input-output life-cycle analysis (EIO-LCA) software; fuel cycles and vehicle end-of-life stages are based on published model results. We find that recent advances in gasoline vehicles, the low petroleum price, and the extensive gasoline infrastructure make it difficult for any alternative fuel to become commercially viable. The most attractive alternative fuel is compressed natural gas because it is less expensive than gasoline, has lower regulated pollutant and toxics emissions, produces less greenhouse gas (GHG) emissions, and is available in North America in large quantities. However, the bulk and weight of gas storage cylinders required for the vehicle to attain a range comparable to that of gasoline vehicles necessitates a redesign of the engine and chassis. Additional natural gas transportation and distribution infrastructure is required for large-scale use of natural gas for transportation. Diesel engines are extremely attractive in terms of energy efficiency, but expert judgment is divided on whether these engines will be able to meet strict emissions standards, even with reformulated fuel.

    In the present scenario, the emission from automobiles is becoming a serious problem to the environment. Automobiles, thermal power stations and Industries majorly constitute to the emission of CO2, CO and HC. Though the CO2 available in the atmosphere will be captured by oceans, grasslands; they are not enough to control CO2 present in the atmosphere completely. Also advances in engine and vehicle technology continuously to reduce the emission from engine exhaust are not sufficient to reduce the HC and CO emission. This work concentrates on design, fabrication and analysis to reduce CO2, CO and HC emission from exhaust of automobiles by using molecular sieve 5A of 1.5mm. In this paper, the details of the fabrication, results and discussion about the process are discussed.

    The present average of automobile CO{sub 2} emission in Korea is about 220g/km, so it is hard to achieve reduction goal concluded with EU with present technology capability. In such a situation, it is required a long-term R and D strategy on direct jet engine, hybrid engine, diesel automobile development and other mileage improving technology which need huge initial investment cost. Furthermore, the efforts on alternative fuel automobile technology are needed. When a long-term strategy of corporation and a competitiveness policy of government are integrated properly, then it is possible to establish two goals, environmental protection and maintenance of industrial competitiveness, simultaneously. However, the emission reduction goal that is proposed by EU is still too high to achieve for Korean companies.

    In this paper, the impression of various kinds of auditory signals currently used in automobiles and a comprehensive evaluation were measured by a semantic differential method. The desirable acoustic characteristic was examined for each type of auditory signal. Sharp sounds with dominant high-frequency components were not suitable for auditory signals in automobiles. This trend is expedient for the aged whose auditory sensitivity in the high frequency region is lower. When intermittent sounds were used, a longer OFF time was suitable. Generally, "dull (not sharp)" and "calm" sounds were appropriate for auditory signals. Furthermore, the comparison between the frequency spectrum of interior noise in automobiles and that of suitable sounds for various auditory signals indicates that the suitable sounds are not easily masked. The suitable auditory signals for various purposes is a good solution from the viewpoint of universal design.

    There have been no reports in the literature of esophageal rupture in adults resulting from an explosion of an automobile tire. We report the first case of just such an occurrence after an individual bit into a tire, causing it to explode in his mouth. A 47-year-old Han Chinese man presented with massive hemorrhage in his left eye after he accidentally bit an automobile tire tube which burst into his mouth. He was diagnosed with esophageal rupture based on a chest computed tomography scan and barium swallow examination. Drainage of empyema (right chest), removal of thoracic esophagus, exposure of cervical esophagus, cardiac ligation and gastrostomy were performed respectively. After that, esophagogastrostomy was performed. Successful anastomosis was obtained at the neck with no postoperative complications 3 months after the surgery. The patient was discharged with satisfactory outcomes. We present this case report to bring attention to esophageal rupture in adults during the explosion of an automobile tire tube in the mouth.

    This paper describes the improvement of the refrigerant flow control method by using an electronic expansion valve (EEV) which is driven by a stepper motor in automobile air conditioning system. An EEV can make a quick response to the abrupt change in the refrigerant flow rate during the change in automobile speed and the thermostatic on/off operation. The flow rate characteristic of the EEV for automobile air conditioning was presented. A microcontroller is used to receive the input signal and generate the output signal to control the opening of the EEV. The fuzzy self-tuning proportional-integral-derivative (PID) control method is employed. Experimental results show that the new control method can feed adequate refrigerant flow into the evaporator in various operations. The evaporator discharge air temperature has dropped by approximately 3{sup o}C as compared with that of the conventional PID control system. (author)

    This report explores the visibility of an Electroluminescent (EL) display for automotive use. Displays for automobiles are exposed to the direct rays of the sun and forced to operate in wide temperature range. Therefore, luminous flux density by the lighting on EL display panel and operating environment temperature must be considered for the visibility evaluation. Sensory evaluation on the visibility and physical measurements such as contrast, chromaticity difference in accordance with the viewing angle change indicate that the visibility of the EL display for automobiles is advantageous over other displays. 6 refs., 11 figs., 1 tab.

Por meio de um exame de algumas práticas chave da cena contemporânea, como as composições coreográficas de Myriam Gourfink, Isabelle Choinière e o projeto de assinatura do movimento de Martine Époque e Denis Poulin, analisa-se o impacto das tecnologias sobre a redefinição do processo da percepção do performer na composição do movimento e a mudança da noção de presença. Nesse sentido, tem-se uma série das modificações que também influenciam a percepção do espectador. Portanto, discute-se a noção de empatia e tenta-se descobrir como ela se aplica ao contexto de uma imagem digital do corpo.

En un esfuerzo por explicar estos activos, han aparecido teorías como las basadas en la gestión del conocimiento, en el capital intelectual entre otras donde la importancia del valor de la empresa pasa de los recursos tangibles a los intangibles. La relativa juventud de este marco teórico, incorporado recientemente a las ciencias de la Administración, hace que no exista una nítida definición y diferenciación entre los conceptos que intervienen en esta nueva riqueza y que habitualmente se vinculen a una misma realidad.

La ansiedad se relaciona de forma negativa con el rendimiento y en particular, la ansiedad estadística puede ser un constructo clave en la mejora de la enseñanza de esta materia y afines. La Statistical Anxiety Scale (Vigil-Colet, Lorenzo-Seva y Condon, 2008 se creó con la pretensión de ser útil para predecir el rendimiento académico en estadística. Se fundamenta en tres dimensiones de ansiedad referidas a tres aspectos específicos: respecto al examen, cuando se pide ayuda en la comprensión de estadística y en el proceso de interpretación de resultados. Esta estructura de tres factores fue hallada en un primer momento por los autores de la escala y en una primera validación corroborada en estudiantes italianos y españoles. El presente estudio pretende añadir nueva evidencia sobre la fiabilidad y validez de la escala, empleando en el estudio de fiabilidad técnicas estadísticas robustas, y ampliando el estudio de la validez respecto a su principal criterio, el rendimiento académico, ya que no puede ser considerado sinónimo de autoeficacia.

    International Nuclear Information System (INIS)

    MaClean, H.L.; Lave, L.B.

    2000-01-01

    The authors analyze alternative fuel-powerstrain options for internal combustion engine automobiles. Fuel/engine efficiency, energy use, pollutant discharges, and greenhouse gas emissions are estimated for spark and compression ignited, direct injected (DI), and indirect injected (II) engines fueled by conventional and reformulated gasoline, reformulated diesel, compressed natural gas (CNG), and alcohols. Since comparisons of fuels and technologies in dissimilar vehicles are misleading, the authors hold emissions level, range, vehicle size class, and style constant. At present, CNG vehicles have the best exhaust emissions performance while DI diesels have the worst. Compared to a conventional gasoline fueled II automobile, greenhouse gases could be reduced by 40% by a DI CNG automobile and by 25% by a DI diesel. Gasoline- and diesel-fueled automobiles are able to attain long ranges with little weight or fuel economy penalty. CNG vehicles have the highest penalty for increasing range, due to their heavy fuel storage systems, but are the most attractive for a 160-km range. DI engines, particularly diesels, may not be able to meet strict emissions standards, at least not without lowering efficiency

    The analysis of paint chips is of great interest to forensic investigators, particularly in the examination of hit-and run cases. This study proposes a direct and rapid method in classifying automobile paint samples based on colorimetric data sets; absorption value, reflectance value, luminosity value (L), degree of redness (a) and degree of yellowness (b) obtained from video spectral comparator (VSC) technique. A total of 42 automobile paint samples from 7 manufacturers were analysed. The colorimetric datasets obtained from VSC analysis were subjected to chemometric technique namely cluster analysis (CA) and principal component analysis (PCA). Based on CA, 5 clusters were generated; Cluster 1 consisted of silver color, cluster 2 consisted of white color, cluster 3 consisted of blue and black colors, cluster 4 consisted of red color and cluster 5 consisted of light blue color. PCA resulted in two latent factors explaining 95.58 % of the total variance, enabled to group the 42 automobile paints into five groups. Chemometric application on colorimetric datasets provide meaningful classification of automobile paints based on their tone colour (L, a, b) and light intensity These approaches have the potential to ease the interpretation of complex spectral data involving a large number of comparisons.

    To investigate the work-related musculoskeletal disorders among automobile assembly workers, to discusses the related risk factors and their relationship. The selected 1508 automobile assembly workers from a north car manufacturing company were regarded as the study object. The hazard zone jobs checklist, Nordic musculoskeletal symptom questionnaire (NMQ) and pain questionnaire were used to perform the epidemiological cross-sectional and retrospective survey and study for the General status, awkward ergonomics factors and related influencing factors, and musculoskeletal disorders of workers. The predominant body sites of occurring WMSDs among automobile assembly workers were mainly low back, wrist, neck and shoulders, the predominant workshop section of occurring WMSDs were mostly concentrated in engine compartment, interior ornament, door cover, chassis and debugging section. The predominant body site of WMSDs among engine compartment and chassis section workers was low back, interior ornament workers were low back and wrist, door cover workers was wrist, chassis workers was low back, debugging workers were neck and low back. Neck musculoskeletal disorders had the trend with the increase of a body height; Smoking may increase the occurrence of musculoskeletal disorders. The WMSDs appears to be a serious ergonomic proble assem among automobile assembly workers, predominant occurring site of WMSDs is with different workshop section, its characteristics is quite obvious, probably related to its existing awkward work position or activities. The worker height and smoking habits may be important factors which affect musculoskeletal disorders happen.

    created using hybrid FE-SEA method. The modal density was calculated using analytical method and finite element method; the damping loss factors of the structural and acoustic cavity subsystems were also calculated with analytical method; the coupling loss factors between structure and structure, structure and acoustic cavity were both calculated. Four different kinds of excitations including road excitations, engine mount excitations, sound radiation excitations of the engine, and wind excitations are exerted on the body of automobile when the automobile is running on the road. All the excitations were calculated using virtual prototype technology, computational fluid dynamics (CFD, and experiments realized in the design and development stage. The interior noise of the automobile was predicted and verified at speed of 120 km/h. The predicted and tested overall SPLs of the interior noise were 73.79 and 74.44 dB(A respectively. The comparison results also show that the prediction precision is satisfied, and the effectiveness and reliability of the hybrid FE-SEA model of the automobile is verified.

    Full Text Available El turismo sexual ha sido objeto de creciente atención en los estudios sobre turismo. La mayoría de los autores se ocupan de su expansión en el Sudeste asiático, con Tailandia como mascarón de proa. Para un grupo de investigadores el turismo sexual en ese área refleja, ante todo, una estrategia de desarrollo económico capitalista favorecida por los gobiernos locales y agencias económicas internacionales. Otros autores enfatizan que constituye otra nueva forma de dominación simbólica de Occidente sobre Oriente. Este trabajo analiza críticamente esas posiciones y concluye que el estudio de la prostitución en esos países debe ser objeto de un examen más general, enraizado en sus tradiciones familiares y culturales.Sex tourism has recently become one important topic in tourism research. Many authors discuss its expansion in Southeast Asia, significantly in Thailand. A sizeable number of researchers think that it reflects another facet of the international division of labor induced by capitalist development. This strategy has been consistently pursued by local governments and international agencies. Others see in sex tourism a new form of symbolic subjection of the Orient. This paper discusses those two points of view and concludes that prostitution in the area needs broader vistas including local family structures and cultural traditions.

    2017-09-01

    In computer vision system, it is a challenging task to robustly reconstruct complex 3D geometries of automobile castings. However, 3D scanning data is usually interfered by noises, the scanning resolution is low, these effects normally lead to incomplete matching and drift phenomenon. In order to solve these problems, a data-driven local geometric learning model is proposed to achieve robust reconstruction of automobile casting. In order to relieve the interference of sensor noise and to be compatible with incomplete scanning data, a 3D convolution neural network is established to match the local geometric features of automobile casting. The proposed neural network combines the geometric feature representation with the correlation metric function to robustly match the local correspondence. We use the truncated distance field(TDF) around the key point to represent the 3D surface of casting geometry, so that the model can be directly embedded into the 3D space to learn the geometric feature representation; Finally, the training labels is automatically generated for depth learning based on the existing RGB-D reconstruction algorithm, which accesses to the same global key matching descriptor. The experimental results show that the matching accuracy of our network is 92.2% for automobile castings, the closed loop rate is about 74.0% when the matching tolerance threshold τ is 0.2. The matching descriptors performed well and retained 81.6% matching accuracy at 95% closed loop. For the sparse geometric castings with initial matching failure, the 3D matching object can be reconstructed robustly by training the key descriptors. Our method performs 3D reconstruction robustly for complex automobile castings.

  20. Viagens em Troia com Freire:a tecnologia como um agente de emancipação

    Directory of Open Access Journals (Sweden)

    Paulo Blikstein

    Full Text Available Resumo A rápida penetração de novas tecnologias na escola constitui uma oportunidade para a disseminação da filosofia de dois importantes teóricos da educação: Seymour Papert e Paulo Freire. As tecnologias digitais possibilitam formas diversas e inovadoras de trabalhar, expressar e construir. Essa adaptabilidade camaleônica da mídia computacional promove diversidade epistemológica (TURKLE; PAPERT, 1991, criando um ambiente no qual os alunos, na sua própria voz, podem concretizar suas ideias e projetos com motivação e empenho. Este artigo descreve uma implementação conduzida em uma escola pública brasileira e gera uma série de princípios de design de ambientes Papert/Freireanos, analisando o empenho intelectual e emocional dos estudantes, suas trajetória de aprendizado e a complexidade de seus projetos, que variaram de robôs controlados por computador a filmes de ficção científica. O artigo discute um modelo de implementação com quatro componentes: primeiro, identificar um tema gerador relevante para a comunidade; segundo, partir da cultura e da experiência tecnológica da comunidade como base para a introdução de novas tecnologias; terceiro, deliberadamente usar uma abordagem de mídia mista, em que alta e baixa tecnologia coexistem; por fim, deslocar certos protocolos sociais e comportamentais considerados normais nas escolas, mesmo aqueles aparentemente irrelevantes para o ensino e a aprendizagem. Conclui-se que tal utilização de tecnologias expressivas pode ser um poderoso agente de emancipação à Paulo Freire e, em especial, em comunidades economicamente carentes.

    Full Text Available Según el autor, las sociedades europeas siguen inspirando las políticas sociales en un código (estatal de inclusión ?al que aquí se denomina lib/lab (mezcla de liberalismo y laborismo? que en el pasado ha constituido un factor de progreso, pero que actualmente resulta cada vez más débil y obsoleto. Las políticas sociales encuentran límites estructurales en sus posibilidades de innovación porque están formuladas como compromisos entre Estado y mercado, utilizando al sector terciario para remediar los fracasos de los otros dos sectores. De hecho, los sistemas sociales gobernados por lógicas lib/lab se encaminan a una crisis irreversible. El documento ilustra las nuevas tendencias de configuración de las políticas sociales, que aquí se denominan "societarias ". Se caracterizan por dos novedades principales: primero, por el hecho de que confían la inclusión social a una ciudadanía compleja (concebida como entrelazamiento de ciudadanía estatal y ciudadanía societaria, en la cual poseen un papel primordial los sujetos colectivos de la sociedad civil; segundo, porque definen el Bienestar, los servicios y los derechos sociales mediante un código simbólico de tipo relacional. En términos de orden institucional, se trata de pasar a un "cuarto modelo de Estado del Bienestar", es decir, a un Estado social de cuarta generación, después de haber dejado atrás el paternalista, el asistencial y el intervencionista. El autor lo denomina Estado social relacional.

    Full Text Available Los sectores de ensamble de autos y fabricación de autopartes en Colombia describen las presiones que ejerce el entorno competitivo internacional sobre la eficiencia y la calidad. Estas presiones han incidido en la adopción de nuevas formas de organización del trabajo y en el cambio casi generalizado de políticas de personal durante los últimos quince años. En este artículo se analiza e ilustra un conjunto de transformaciones significativas en las relaciones laborales en esta rama industrial, con base en información cualitativa de las tres más importante plantas terminales del país y de dos notables compañías fabricantes de componentes. Aunque las dinámicas no son homogéneas, se puede decir que el proceso más generalizado ha sido el debilitamiento de la negociación colectiva y las relaciones industriales, como bases para la interacción y el acuerdo entre capital y trabajo. Las políticas de personal y formas de organización de la producción han conducido en casi todas los espacios a una definición autoritaria y unilateral de las relaciones laborales y de las condiciones de trabajo por parte de las empresas. Los nuevos modelos de relaciones laborales se van conformando a través de prácticas organizativas y de gestión de personal que combinan mecanismos tradicionales de coacción y flexibilidad (políticas antisindicales y trabajo temporal con elaboradas y sutiles estrategias para generar entre los trabajadores sentido de pertenencia y compromiso con los fines de las empresas (adoctrinamiento en el discurso empresarial de la competitividad, llamados a la participación y autocontrol para el logro de mejores estándares de calidad, prácticas neopaternalistas, entre otras.

  13. Daredevils and early birds: Belgian pioneers in automobile racing and aerial sports during the belle époque.

    Ameye, Thomas; Gils, Bieke; Delheye, Pascal

    2011-01-01

    During the belle époque, Belgium was a trend-setting nation in many domains, including motorised sports. Belgian automobile racers and pilots shattered world records and became international stars. Striking was the shift in sports. Indeed, around 1896, sporting members of the leisure class stepped from the bicycle into the automobile and, around 1908, from the automobile into the airplane.

    There has been much speculation about the recent upsurge in crude oil prices and the effect it will have on the economy and business. The objective of this paper is to investigate the relationship between oil prices and stock prices of automobile manufacturers. We add an oil price factor, measured alternatively by the excess change in WTI crude oil prices or the excess return on an energy ETF, to the Fama-French three-factor model over the period March 20, 2001 to September 30, 2008. Our dependent variable is the excess return on a price-weighted index of automobile manufacturers. Results indicate that oil prices add value to the pricing model, particularly for manufacturers specializing in SUVs and for a subperiod following the Iraq invasion on March 19, 2003. (author)

    2018-04-01

    Full Text Available This research developed a novel proportional pressure control valve for an automobile hydraulic braking actuator. It also analyzed and simulated solenoid force of the control valves, and the pressure relief capability test of electromagnetic thrust with the proportional valve body. Considering the high controllability and ease of production, the driver of this proportional valve was designed with a small volume and powerful solenoid force to control braking pressure and flow. Since the proportional valve can have closed-loop control, the proportional valve can replace a conventional solenoid valve in current brake actuators. With the proportional valve controlling braking and pressure relief mode, it can narrow the space of hydraulic braking actuator, and precisely control braking force to achieve safety objectives. Finally, the proposed novel proportional pressure control valve of an automobile hydraulic braking actuator was implemented and verified experimentally.

    We examined the risk factors for automobile accidents caused by falling asleep while driving in subjects with obstructive sleep apnea syndrome (OSAS). We asked licensed drivers with history of snoring and excessive daytime sleepiness who had undergone polysomnography (PSG) at the Department of Sleep Medicine/Sleep Disorders Center at Aichi Medical University Hospital to complete the questionnaires on accidents caused by falling asleep while driving. As a subjective measure of sleepiness, we used the Epworth sleepiness scale (ESS). Based on PSG results, 2387 subjects diagnosed with OSAS were divided into three groups according to apnea-hypopnea index (AHI): mild-to-moderate (5 ≤ AHI accidents in the past 5 years due to falling asleep. Our multivariate analysis suggests that scores on the ESS and patient-reported frequency of feeling drowsy while regular driving and working are related to automobile accidents caused by falling asleep while driving.

  4. Reduced-Order Computational Model for Low-Frequency Dynamics of Automobiles

    Directory of Open Access Journals (Sweden)

    A. Arnoux

    2013-01-01

    Full Text Available A reduced-order model is constructed to predict, for the low-frequency range, the dynamical responses in the stiff parts of an automobile constituted of stiff and flexible parts. The vehicle has then many elastic modes in this range due to the presence of many flexible parts and equipment. A nonusual reduced-order model is introduced. The family of the elastic modes is not used and is replaced by an adapted vector basis of the admissible space of global displacements. Such a construction requires a decomposition of the domain of the structure in subdomains in order to control the spatial wave length of the global displacements. The fast marching method is used to carry out the subdomain decomposition. A probabilistic model of uncertainties is introduced. The parameters controlling the level of uncertainties are estimated solving a statistical inverse problem. The methodology is validated with a large computational model of an automobile.

    2008-01-01

    Full Text Available With the advancement of digital signal processing technologies, consumers are more concerned with the quality of multimedia entertainment in automobiles. In order to meet this demand, an audio enhancement system is needed to improve bass reproduction and cancel engine noise in the cabins. This paper presents an integrated active noise control system that is based on frequency-sampling filters to track and extract the bass information from the audio signal, and a multifrequency active noise equalizer to tune the low-frequency engine harmonics to enhance the bass reproduction. In the noise cancellation mode, a maximum of 3 dB bass enhancement can be achieved with significant noise suppression, while higher bass enhancement can be achieved in the bass enhance mode. The results show that the proposed system is effective for solving both the bass audio reproduction and the noise control problems in automobile cabins.

    2015-12-01

    Full Text Available This article examines a new social geography opened by the use of the automobile and maps in the Mexican territory between 1929 and 1962. In this temporary scenery, the construction of roads during a considerable span of the 20th Century has been identified as part of the modernization plan of the revolutionary governments of Mexico. This infrastructure furnished the opportunity of getting to know the wide variety of landscapes of the country as never before. A set of new traveling experiences was offered to the middle class at the same time that such diversity of Mexican landscapes caused different emotions through the “pleasure” of ersonally contemplating the rivers, mountains, trees, vegetation, the sea, the hamlets, towns or cities. A central element of this perspective was occupied by the automobile; its presence in Mexico meant a cultural novelty with deep effects and changes in the Mexican society of the 20th Century. The new technological element worked as a new mechanism that started circulating by the roads to observe the landscape. Because of this, we propose the application of three key concepts of space analysis: the circulation territory, the visual territory and the experience territory. Each one of them represents the many sides of the landscape as one study object, and of geography interest, as described below. The territory of circulation came about when the railroads decline started in the twenties and consolidated in the sixties of the past century. That is why in this section we first place a comparative perspective of the motorization levels through the number of inhabitants per automobile in several Latin-American countries having available ordered historical statistics on the matter. Results show a long construction of the automobile culture in this geographic region; construction that incorporated new communication and evolution forms of social groups.

  9. Automobile exhausts as a source for the environmental pollution by polychloro-dibenzodioxins and -dibenzofurans

    International Nuclear Information System (INIS)

    Ballschmiter, K.; Bacher, R.; Riehle, U.; Swerev, M.

    1990-01-01

    This research project was focussed on the analysis of polyhalogenated dibenzodioxins (''dioxins'') and dibenzofurans (''furans'') emitted through automobile exhausts (halogen = chlorine or bromine). High-resolution selective capillary gas chromatography coupled with mass-selective detection was used. The two compound groups show basic differences in pattern and concentrations for traffic-related samples. In the ''dioxin''-series the higher-chlorinated dibenzodioxins (increasing from Cl 4 to Cl 8 ) are preferentially found, in contrast to the ''furane'', present in higher amounts, for which the lower-halogenated dibenzofurans are more important (decreasing from Cl 1 to Cl 6 and from Br 1 to Br 4 ). The distribution of the dioxin- and furan isomers produced corresponds closely to the so-called ''2,6-type'' pattern which is due to a retarded oxidation and/or a stabilization of phenoxy-intermediates containing the 2,6- or 2,4,6-substitution pattern. To what extent a particular dioxin/furan immission is due to automobile-related emissions can, in the light of the present results, be estimated only by taking several factors into account; source remoteness, the predominance of brominated or partly brominated dibenzofurans over the chlorinated congeners, the presence of other, also halogenated, polycyclic aromatics related to the automobile combustion engine. Areas close to traffic are primarily or completely influenced by the ''dioxin''-emissions of automobiles. For the calculation of the toxic equivalents (TE) for traffic-related emissions, the most important of the ''2,3,7,8''-substituted congeners are the furans 2,3,7,8-Cl 4 DF (F 83) and 2,3,4,7,8-Cl 5 DF (F 114) as well as the dioxins 1,2,3,4,6,7,8-Cl 7 DD (D 73) and octachlorodibenzodioxin (D-75).

    Full Text Available The fuel cell principle was discovered by Sir Grove 150 years ago. However material problems prohibited its commercialization for a long time. A change has been occurring during the last 30 years, so two types of fuel cell technologies can be distinguished: low and high temperature operation cells. Nowadays, only phosphoric acid cells are commercially offered as 200 kWel power plants. Membrane cells are more suitable for automobile electrotraction with a very low (or no environmental impact. The fuel continues, however, to play a very particular role, since hydrogen is not easy to store and to transport. The more promising target is the utilization of liquid methanol. The Brazilian scenario concerning this kind of technology is discussed.

  17. Managing bottlenecks in manual automobile assembly systems using discrete event simulation

    2013-08-01

    Full Text Available Batch model lines are quite handy when the demand for each product is moderate. However, they are characterised by high work-in-progress inventories, lost production time when changing over models, and reduced flexibility when it comes to altering production rates as product demand changes. On the other hand, mixed model lines can offer reduced work-in-progress inventory and increased flexibility. The object of this paper is to illustrate that a manual automobile assembling system can be optimised through managing bottlenecks by ensuring high workstation utilisation, reducing queue lengths before stations and reducing station downtime. A case study from the automobile industry is used for data collection. A model is developed through the use of simulation software. The model is then verified and validated before a detailed bottleneck analysis is conducted. An operational strategy is then proposed for optimal bottleneck management. Although the paper focuses on improving automobile assembly systems in batch mode, the methodology can also be applied in single model manual and automated production lines.

    Carbon dioxide has become a popular working medium in heat pump water heaters and mobile heat pumping systems due to its environment friendliness and its excellent thermal and transport properties in transcritical cycle. It also looks bright as a complete solution to environmental problem associated with automobile air conditionings. As high efficient mobile engines with less waste heat have been developed, extra heating of the passenger compartment is needed in the cold season. In this investigation, three heating solutions for automobile CO 2 air conditioning systems are provided. They are a bypass CO 2 heating cycle, a conventional CO 2 transcritical heat pump cycle and a high capacity heat pump cycle with economizer. These three solutions are compared with the viewpoints of the efficiency and heating capacity. The test results show that the heating capacity of the bypass heating method is only enough for a small automobile although it has the advantage of simple construction and low investment. The heat pump cycle with economizer applying a special construction reciprocating compressor can obtain a highest capacity even in cold climate. But the investment increase for economizer heat pump cycle includes both the modification of the compressor and the flash tank. And the COPh of economizer heat pump cycle is higher than bypass heating cycle, but lower than conventional heat pump cycle due to the highest capacity operation condition. (author)

    Although use of automobile air conditioning (AC) was shown to reduce in-vehicle particle levels, the characterization of its microbial aerosol exposure risks is lacking. Here, both AC and engine filter dust samples were collected from 30 automobiles in four different geographical locations in China. Biological contents (bacteria, fungi, and endotoxin) were studied using culturing, high-throughput gene sequence, and Limulus amebocyte lysate (LAL) methods. In-vehicle viable bioaerosol concentrations were directly monitored using an ultraviolet aerodynamic particle sizer (UVAPS) before and after use of AC for 5, 10, and 15 min. Regardless of locations, the vehicle AC filter dusts were found to be laden with high levels of bacteria (up to 26,150 CFU/mg), fungi (up to 1287 CFU/mg), and endotoxin (up to 5527 EU/mg). More than 400 unique bacterial species, including human opportunistic pathogens, were detected in the filter dusts. In addition, allergenic fungal species were also found abundant. Surprisingly, unexpected fluorescent peaks around 2.5 μm were observed during the first 5 min use of AC, which was attributed to the reaerosolization of those filter-borne microbial agents. The information obtained here can assist in minimizing or preventing the respiratory allergy or infection risk from the use of automobile AC system.

    The activity of three-way catalysts is highly dependent on the reactants present in the automobile exhaust gases (CO, NO x , HC, O 2 , H 2 O, CO 2 , N 2 ) as well as their relative concentration. Thus, the influence of each reactant on the kinetic behavior of the whole mixture makes difficult to establish the accurate kinetics of the system. Activity experiments carried out close to the real operation conditions (GHSV, concentration, etc.) with a Pt/CeO 2 /Al 2 O 3 catalyst supplied data on the CO and HC oxidation and NO reduction reactions in environments formed by different reactant combinations (from binary mixtures to the whole mixture simulating the real conditions at the automobile converter).The obtained results have shown notable variations in the oxidation/reduction mechanisms depending on the presence (or absence) of components in the environment. The presence of water always promoted the three-way activity of the catalyst. The compensation effect applied to the CO, NO and HC conversions confirmed that kinetic expressions obtained with partial mixtures (not very close to the real converter environment) have only limited application for determining the whole kinetic scheme occurring in the automobile converters

    The accessibility of ophthalmologists appears to influence the quality of screening for diabetic retinopathy (DR). The principal objective of this study was to analyze the effect of automobile travel time to the closest ophthalmologist on the time to DR screening. This historical cohort study used reimbursement databases from the principal national health insurance fund. Patients were included if they had been reimbursed at least thrice for oral antidiabetic medications in the 12 months before the study start date. Patients were followed up from January 1, 2008, for 4 years. The expected event was a DR screening by an ocular fundus examination. The automobile travel time to the nearest ophthalmologist was calculated by the distance between communes, estimated by appropriate software. A Kaplan-Meier curve and a multivariate Cox model were used to model the effect of travel time on the time until DR screening. A sensitivity analysis of travel time described the results of the Cox model. At the start of 2008, 6,573 patients living in 328 different municipalities were included. The multivariate model found that patients living 60 min or more away from an ophthalmologist had a lower instantaneous probability of DR screening than those living travel time. Increased automobile travel time for patients with diabetes to the nearest ophthalmologist was associated with a longer time to DR screening.

    Work-related fatigue is common among automobile factory employees. The purpose of this study was to assess fatigue of employees at a Chinese automobile factory. 238 employees (119 engineers and 119 workers) participated in this study. The following questionnaires were completed: demographic survey questionnaire, working condition questionnaire (WCQ), functional assessment of chronic illness therapy-fatigue (FACIT-F), subscales of multidimensional fatigue inventory (MFI), and Pittsburgh sleep quality index (PSQI). Both engineers and workers experienced fatigue. The workers (35.6 years old, SD = 6.7) generally felt more fatigue than engineers (42.6 years old, SD = 6.4). The engineers claimed to be more satisfied with the working conditions than workers. The WCQ showed good properties for assessing work-related factors, which were significantly correlated with fatigue (r = 0.568 for engineers and r = 0.639 for workers). For engineers, general fatigue was observed regularly and frequently, and for workers, physical fatigue usually had a long duration. The fatigue was significantly correlated with work-related factors, especially working environment and monotony. For workers, the duration of the work day also affected their fatigue. Some improvements to the working condition in this automobile factory should be considered.

    Surveys have been made on the characteristics of environmentally harmonizing automobiles, and the status of development and introduction thereof inside and outside the country. Discussions were given on the possibility of introducing electric automobiles in Japan. In developing environmentally harmonizing automobiles in Japan, works have been executed on low pollution type components such as lean burn engines, electric automobiles, gasoline engine and electric motor hybrid cars, methanol fueled cars, and fuel cell automobiles. Some of them are already in use in spite of their high price. In America, a cooperation project for the next generation cars has been implemented by mobilizing industrial, academic and governmental organizations. Based on the achievements thereof, the car makers have announced their original advanced cars respectively. In the EU, development of low exhaust gas cars and zero emission cars is being carried out jointly by the related industries setting years 2003 to 2005 as the target. An urban type traffic system utilizing electric vehicles, and a traffic system dividing movements of short distance and long distance are proposed as the means to introduce the future electric automobiles.

    Full Text Available http://dx.doi.org/10.5007/1807-9288.2013v9n2p76 Este artigo propõe uma reflexão em torno das dinâmicas de conversação eletrônica presentes em trabalhos de arte e tecnologia. Estas produções possuem sistemas que respondem a sentenças de seus interlocutores com proposições inteligíveis, dentro da ideia de uma linguagem natural, imitando uma conversa entre humanos. Essa conversação pode ser por texto ou mesmo por voz, quando o sistema possui recursos de reconhecimento de fala. Quando fruídos estes trabalhos revelam um interessante fenômeno, chamado de “Efeito Eliza”: a tendência humana de antropomorfizar os dispositivos tecnológicos, lendo comportamentos e respostas como resultados de uma “emoção humana” ainda que estes sejam apenas resultados aleatórios, repetitivos ou mesmo vazios de sentido. A denominação remete ao programa Eliza, apresentado em 1966 pelo cientista da computação alemão Joseph Weizenbaum nos Estados Unidos, que viria a ser um dos programas de Inteligência Artificial mais conhecidos do mundo. Do ponto de vista técnico, alguns destes trabalhos se aproximam muito da engenharia dos chatbots – robôs de conversação – que atualmente são bastante comuns na rede Internet para fins educacionais, comerciais ou mesmo, de entretenimento, como um “amigo virtual”. Neste contexto, é apresentada uma suposta teleperformance, capitaneada por um “artista tecnológico” chamado Mimo Steim. Assim como outras incursões do gênero, a ação envolve o potencial relacional de sistemas de conversação eletrônica em trabalhos de arte e tecnologia.

    Full Text Available O desenvolvimento de técnicas voltadas ao prolongamento da vida acarretou mudanças significativas na concepção de morte. Este artigo analisa as representações contemporâneas da "morte natural" e sua relação com o uso de tecnologias médicas. Através de revisão bibliográfica, são examinadas as concepções de "morte natural" e de "morrer bem" construídas pelos diversos atores sociais envolvidos no processo do morrer. A literatura evidencia a construção contemporânea de um ideário e de uma trajetória necessários à realização do modelo da "boa morte". Esse modelo do "morrer bem" é construído em contraposição ao uso de técnicas para o prolongamento da vida. Estudos apontam a complexidade e ambivalência presentes no que seriam a morte natural ou não-natural, pois essas representações se encontram imbricadas com a concepção da "boa morte" como escolhida e produzida pelo doente. Deste modo, a tecnologia médica torna-se intrinsecamente constitutiva do "morrer natural".The development of techniques to prolong life has brought significant changes in the conceptualization of death. This article analyzes contemporary representations of "natural death" and their relationship to the use of medical technologies. Based on a literature review, the article examines the concepts of "natural death" and "dying well" constructed by the various social actors involved in the process of dying. The literature reveals the contemporary construction of a necessary set of ideals and pathway for achieving the model of a "good death". The "dying well" model is constructed in opposition to techniques for prolonging life. The studies point to the complexity and ambivalence of what is presented as "natural" versus "unnatural" death, since such representations are intertwined with the concept of a "good death" as that which is "chosen and produced" by the patient. Thus, medical technology becomes intrinsically constitutive for a "natural death".

Na delimitação do estudo, procuramos investigar as dificuldades dos professores com a utilização dos novos recursos tecnológicos, considerando-se os fatores internos e externos que possam estar inviabilizando o sucesso da inclusão digital no ambiente escolar da rede pública estadual. Assim, por meio da pesquisa qualitativa e avaliativa propiciada por um projeto de ação, buscamos entender as interferências que ocorrem na prática docente por meio de observações direcionadas ao desempenho dos professores na utilização dos recursos tecnológicos da sala de informática como instrumentos de desenvolvimento do ensino dos conteúdos escolares. Os resultados obtidos no projeto de ação originaram-se de declarações dos sujeitos e de observações estabelecidas nos módulos de capacitação e de aplicação dos planos de aulas. Esses resultados convergem para os fatores desestimulantes como: excesso de movimentações dos docentes entre as escolas; ausência de pessoas credenciadas na própria escola capazes de coordenar as novas tecnologias educacionais e proporcionar segurança aos docentes; falta de capacitações no próprio ambiente escolar; carência de multiplicadores locais; ausência da previsão de tempo da preparação de aulas com os novos recursos tecnológicos na própria carga horária do professor e a inexistência de regulamentação na gestão administrativa que valorize o certificado da formação continuada. Enfim, as informações analisadas nessa pesquisa pelos aspectos positivos e negativos oferecem espaço para novas investigações dessa natureza.

A auditoria de TI tem como função principal avaliar o processo de gestão, no que se refere aos seus diversos aspectos, tais como a governança corporativa, gestão de riscos de TI e procedimentos de aderência às normas regulatórias, apontando eventuais desvios e vulnerabilidades, como também oferecendo alternativas de soluções para esses diversos problemas. No âmbito do controle externo, os Tribunais de Contas começam a reconhecer a necessidade de implantar áreas especializadas na realização de Auditoria de TI. Neste contexto, o presente trabalho pretende apresentar quais as abordagens utilizadas nesta área de fiscalização, destacando a importância da Governança de TI como importante instrumento na atuação do controle externo na fiscalização da gestão e do uso da Tecnologia da Informação na Administração Pública.

    Full Text Available Esse artigo visa contribuir para a construção de uma poética feminista no cinema e audiovisual contemporâneo concebida na ideia de trânsito ou fluxos para sujeitos de gênero compreendidas/os fora da lógica dos binarismos “cis” e heteronormativos. Para tanto, atualiza a acepção em Lauretis (1987 de que o cinema se constitui como tecnologia de gênero, e aborda tal premissa no contexto das imagens tecnológicas e digitais através do conceito de percepto de devir feminista. Tal relação proposta engloba a ideia de que a poética feminista atualmente se alicerça cada vez mais na prerrogativa das experiências próprias de personagens subjetificadas/os, por um caminho patêmico no qual mulheres cis e trans não mais são colocadas sob o olhar do outro-homem-dominador, mas, ao contrário, se enunciam sob referências de seus próprios cotidianos e espaços de interlocução. Nesse sentido, a atualização da ideia de tecnologia de gênero para o cinema está ligada ao fato de que tais imagens configuram desterritorializações, devires, tanto no que toca a relação hegemonia-subalternidade no sistema sexo-gênero como no que se refere à própria ideia dos sujeitos legítimos e nomeados no feminismo. Como escopo investigativo, lanço um olhar sobre a produção Dude looks Like a Lady, parte da série de curtas em pornografia feminista intitulada XConfessions (LUST, 2013, 125min, oriundos de relatos em texto sobre fantasias e/ou experiências enviadas pela internet. Apesar de tratar de tal realização em particular, a trago também como espaço de acionamento de outras produções na perspectiva do feminismo, que endossam ou potencializam o lugar da diferença em produções com foco nos sujeitos engendrados.
