    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.

    Strickland, G.

    1979-01-01

    Results of an analysis of hydrogen-fueled automobiles are presented as a part of a continuing study conducted by Lawrence Livermore Laboratory (LLL) on Energy Storage Systems for Automobile Propulsion. The hydrogen is stored either as a metal hydride at moderate pressure in TiFe/sub 0/ /sub 9/Mn/sub 0/ /sub 1/H/sub x/ and at low pressure in MgH/sub x/ catalyzed with 10 wt % Ni, or it is stored in hollow glass microspheres at pressures up to about 400 atm. Improved projections are given for the two hydrides, which are used in combination to take advantage of their complementary properties. In the dual-hydride case and in the microsphere case where Ti-based hydride is used for initial operation, hydrogen is consumed in an internal-combustion engine; whereas in the third case, hydrogen from Ti-based hydride is used with air in an alkaline fuel cell/Ni-Zn battery combination which powers an electric vehicle. Each system is briefly described; and the results of the vehicle analysis are compared with those for the conventional automobile and with electric vehicles powered by Pb-acid or Ni-Zn batteries. Comparisons are made on the basis of automobile weight, initial user cost, and life-cycle cost. In this report, the results are limited to those for the 5-passenger vehicle in the period 1985-1990, and are provided as probable and optimistic values.

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.

    Comfort on automobile seats is lived daily by thousands of drivers. Epistemologically, comfort can be understood under the theory of complexity, since it emerges from a chain of interrelationships between man and several elements of the system. This interaction process can engender extreme comfort associated to the feeling of pleasure and wellbeing or, on the other hand, lead to discomfort, normally followed by pain. This article has for purpose the development of a theoretical model that favours the comfort feature on automobile seats through the identification of its facets and indicators. For such, a theoretical study is resorted to, allowing the mapping of elements that constitute the model. The results present a comfort model on automobile seats that contemplates the (physical, psychological, object, context and environment) facets. This model is expected to contribute with the automobile industry for the development of improvements of the ergonomic project of seats to increase the comfort noticed by the users.

    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

  16. Bundled automobile insurance coverage and accidents.

    Science.gov (United States)

    Li, Chu-Shiu; Liu, Chwen-Chi; Peng, Sheng-Chang

    2013-01-01

    This paper investigates the characteristics of automobile accidents by taking into account two types of automobile insurance coverage: comprehensive vehicle physical damage insurance and voluntary third-party liability insurance. By using a unique data set in the Taiwanese automobile insurance market, we explore the bundled automobile insurance coverage and the occurrence of claims. It is shown that vehicle physical damage insurance is the major automobile coverage and affects the decision to purchase voluntary liability insurance coverage as a complement. Moreover, policyholders with high vehicle physical damage insurance coverage have a significantly higher probability of filing vehicle damage claims, and if they additionally purchase low voluntary liability insurance coverage, their accident claims probability is higher than those who purchase high voluntary liability insurance coverage. Our empirical results reveal that additional automobile insurance coverage information can capture more driver characteristics and driving behaviors to provide useful information for insurers' underwriting policies and to help analyze the occurrence of automobile accidents.

    With mandates and regulatory policies to meet both the California Air Resources Board (CARB) and the Partnership for a New Generation of Vehicles (PNGV), designing vehicles of the future will become a difficult task. As we look into the use of electric and hybrid vehicles, reduction of the required power demand by influential automobile components is necessary in order to obtain performance and range goals. Among those automobile components are accessories. Accessories have a profound impact on the range and mileage of future vehicles with limited amounts of energy or without power generating capabilities such as conventional vehicles. Careful assessment of major power consuming accessories helps us focus on those that need improvement and contributes to attainment of mileage and range goals for electric and hybrid vehicles.

First, we identified the main sources where consumers acquire or seek information about miniature automobiles and discussed their extent of information search. Then, based on logistic regression and optimal scaling regression of statistics, we studied the influences of characteristics of consumers of miniature automobiles on the extent of information search and on Internet usage. The results indicate that consumers often utilize four sources to obtain information about miniature automobiles. The dominant information source for consumers is their friends/family, followed by dealers, newspapers, and TV. Age, occupation, education and income significantly affect the extent of information search, but gender and city of residence do not have significant impacts. Age, city of residence, occupation, education and income produce significant influences on Internet usage. Gender has an insignificant influence on whether a consumer uses the Internet to search for information.

Il paesaggio sonoro tecnologico pervade sempre più il nostro vissuto e ne trasforma le tradizionali percezioni, gli approcci all'ascolto. Occorre però abituarsi a distinzioni meno marcate rispetto al passato: esiste un paesaggio sonoro della vita reale e un paesaggio sonoro artificiale sempre più esteso che è quello presente nei contesti audiovisivi e multimediali: queste due aree si assomigliano sempre di più. Punto di partenza del saggio è la riflessione del teorico più rilevante in merito agli studi sul paesaggio: il musicologo canadese Murray Schafer, posta in confronto con altri rilevanti teorici, di diversa derivazione, che molto hanno contribuito allo sviluppo del settore (qualche esempio: Pierre Shaeffer, Simon Emmerson, Michel Chion. La riflessione si addentra inoltre nei territori del cinema, del multimediale, della musica elettronica, del design acustico.

    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.

    A quarter-automobile active suspension model was proposed. High speed on/off solenoid valves were used as control valves and fuzzy control was chosen as control method . Based on force analyses of system parts, a mathematical model of the active suspension system was established and simplified by linearization method. Simulation study was conducted with Matlab and three scale coefficients of fuzzy controller (ke, kec, ku) were acquired. And an experimental device was designed and produced. The results indicate that the active suspension system can achieve better vibration isolation performance than passive suspension system, the displacement amplitude of automobile body can be reduced to 55%. Fuzzy control is an effective control method for active suspension system.

    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.

    Mechanics are exposed to varied work stressors such as hot noisy environments, strenuous postures, improperly designed tools and machinery and poor psycho-social environments which may exert an influence on their health and safety. The study aimed to examine the occupational injury patterns and identify work stressors associated with injury amongst automobile mechanics. A descriptive ergonomic checklist and questionnaire on general health and psycho-social issues were administered to male workers (N=153). The relative risk factors and correlation statistics were used to identify the work stressors associated with occupational injury. 63% of the workers reported injuries. Cuts were the chief injuries being reported. Poor work environment, machinery and tool characteristics, suffering from poor health and psycho-social stressors were associated with injury occurrence amongst automobile repair workers.

    Full Text Available Background : Automobile repair shop is a place where workers are exposed to harmful chemicals and toxic substances. Objective : To study the occurrence of obstructive and restrictive pulmonary impairment among automobile garage workers. Methods : A cross sectional study involving 151 automobile garage workers from 14 randomly selected garages of urban Kolkata. The study variables were Forced Expiratory Volume in 1 second (FEV 1 , Forced Vital Capacity (FVC, Peak Expiratory Flow Rate (PE FR, age, smoking habit, duration of work, type of work, and respiratory symptoms. The study was analysed using Regression equations, and Chi-square test. Results : All the workers were male. Obstructive impairment was seen in 25.83% of the workers whereas restrictive impairment was seen in 21.19% of the workers. Mixed obstructive and restrictive impairment was seen in 10.6% of the workers. The frequency of obstructive impairment was higher in older workers. In the age group of less than 20 years, 13.6% of the workers had obstructive impairment while 42.86% of workers above 40 years of age had obstructive impairment. Obstructive impairment was more frequently observed in battery repair workers (58.33% and spray painters (37.5% while 16.67% of the body repair workers and 30.19% of the engine mechanics had obstructive impairment. Obstructive impairment was more frequently observed in smokers (53.1 % as compared to ex-smokers (33.3% and non-smokers (6.4%. Obstructive impairment was more frequently observed in workers who had been working for a longer duration. Conclusion: Nearly 36.4% of the automobile garage workers had some form of pulmonary function impairment; obstructive and/or restrictive. The use of personal protective equipment, worker education, and discontinuation of the use of paints containing toxic pigments are recommended.

    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.

    Full Text Available It is too easy to make light of ‘new literacies’ by saying things like: “Well, there are always newer ones coming along”. Such remarks suggest new literacies have a similar kind of life trajectory to an automobile: new in 2009, semi-new in 2010, and old hat by 2011. Against this kind of “that’s so yesterday” perspective, we suggest in this article that ‘new literacies’ are best understood in terms of an historical period of social, cultural, institutional, economic, and intellectual change that is likely to span many decades – some of which are already behind us. We associate new literacies with an historical conjuncture and an ascending social paradigm. From this perspective we suggest that the kinds of practices we currently identify as new literacies will cease to be ‘new’ once the social ways characterizing the ascending paradigm have become sufficiently establised and grounded to be regarded as conventional. Furthermore we suggest that at the heart of the idea of new ethos stuff is the idea of technological change aligning with a range of increasingly popular values.Pensar en las “nuevas alfabetizaciones” con afirmaciones del tipo “seguro que algo más nuevo está al caer” es un recurso fácil, que asimila la trayectoria de las nuevas alfabetizaciones a la de un coche: nuevo en 2009, seminuevo en 2010 y un usado en 2011. Frente a esta perspectiva de “eso ya pasó de moda”, en este artículo proponemos abordar las “nuevas alfabetizaciones” como parte de un periodo de cambios sociales, culturales, económicos e intelectuales cuyo inicio se remonta varias décadas en el tiempo. Desde esta perspectiva sugerimos que “las nuevas alfabetizaciones", entendidas como paradigma social emergente, forman parte de una coyuntura histórica. A su vez sostenemos que este conjunto de nuevas prácticas dejarán de ser “novedosas” cuando los estilos sociales que caracterizan este paradigma emergente se hayan

It is obvious that automobile-dependent urban development is under heavy/powerful influence of the automobile lobby (automobile and oil industries, along with construction. 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.

    1981-01-01

    In steering an automobile, the driver must basically control the direction of the car's trajectory (heading angle) and the lateral deviation of the car relative to a delineated pathway. A previously published linear control model of driver steering behavior which is analyzed from a stability point of view is considered. A simple approximate expression for a stability parameter, phase margin, is derived in terms of various driver and vehicle control parameters, and boundaries for stability are discussed. A field test study is reviewed that includes the measurement of driver steering control parameters. Phase margins derived for a range of vehicle characteristics are found to be generally consistent with known adaptive properties of the human operator. The implications of these results are discussed in terms of driver adaptive behavior.

  4. PRODUCT EFFICIENCY IN THE SPANISH AUTOMOBILE MARKET

    Directory of Open Access Journals (Sweden)

    González, Eduardo

    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.

    This paper investigates the opportunities of deploying distributed sensors within the manufacturing environment of a large scale automobile plant using energy harvesting techniques. Measurements were taken in three domains at the plant in order to characterize ambient energy. Due to the location of the plant, the RF power density for radio access technologies present varied between -127 dBm/cm2 and -113 dBm/cm2. The maximum temperature difference measured within accessible distance from machine parts on the production lines surveyed was 10°C. Indoor lighting was dominant at the plant via fluorescent tubes, with average irradiance of 1 W/m2. The results obtained from this measurement campaign showed that indoor lighting was the most suitable ambient source for energy harvesting.

    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.

    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. [Espanol] Existen diversas fuentes nuevas de energia para generar electricidad.

    Remote sensing of light duty vehicle on-road tailpipe exhaust has been used to measure on-road mass emissions of automobile fleets in Denver for 13 years and in two other U.S. cities for 5 years. Analysis of these fleets shows that newer automobiles, during a period of fairly constant new car standards, have become continually less polluting independent of measurement location. Improving emissions control technology spurred by federal regulations is thought to have brought about these trends.

    The Navier Stokes equation is solved computationally by the Dispersion-Relation-Preserving (DRP) scheme for the flow and acoustic fields associated with a laminar boundary layer flow over an automobile door cavity. In this work, the flow Reynolds number is restricted to R(sub delta*) < 3400; the range of Reynolds number for which laminar flow may be maintained. This investigation focuses on two aspects of the problem, namely, the effect of boundary layer thickness on the cavity tone frequency and intensity and the effect of the size of the computation domain on the accuracy of the numerical simulation. It is found that the tone frequency decreases with an increase in boundary layer thickness. When the boundary layer is thicker than a certain critical value, depending on the flow speed, no tone is emitted by the cavity. Computationally, solutions of aeroacoustics problems are known to be sensitive to the size of the computation domain. Numerical experiments indicate that the use of a small domain could result in normal mode type acoustic oscillations in the entire computation domain leading to an increase in tone frequency and intensity. When the computation domain is expanded so that the boundaries are at least one wavelength away from the noise source, the computed tone frequency and intensity are found to be computation domain size independent.

    Identification of suspected automobile-related lubricants could provide valuable information in forensic cases. We examined that automobile lubricants might exhibit the chemometric characteristics to their individual usages. To compare the degree of clustering in the plots, we co-plotted general industrial oils that were highly dissimilar with automobile lubricants in additive compositions. (1) H-NMR spectroscopy was used with multivariate statistics as a tool for grouping, clustering, and identification of automobile lubricants in laboratory conditions. We analyzed automobile lubricants including automobile engine oils, automobile transmission oils, automobile gear oils, and motorcycle oils. In contrast to the general industrial oils, automobile lubricants showed relatively high tendencies of clustering to their usages. Our pilot study demonstrated that the comparison of known and questioned samples to their usages might be possible in forensic fields.

    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)

    Measurements of the magnetic properties and total contents of Cu, Cd, Pb and Fe in 30 automobile emission particulate samples indicated the presence of magnetic particles in them. The values of frequency dependent susceptibility (χfd)showed the absence of superparamagnetic (SP) grains in the samples. The IRM20 mT (isothermal remanent magnetization at 20 mT)being linearly proportional to SIRM (saturation isothermal remanent magnetization) (R2=0.901), suggested that ferrimagnetic minerals were responsible for the magnetic properties of automobile emission particulates. The average contents of Cu, Cd, Pb and Fe in automobile emission particulates were 95.83, 22.14, 30.58 and 34727.31 mg/kg, respectively. Significant positive correlations exist between the magnetic parameters and the contents of Pb, Cu and Fe. The magnetic parameters of automobile emission particulates reflecting concentration of magnetic particles increased linearly with increase of Pb and Cu content, showed that the magnetic measurement could be used as a preliminary index for detection of Pb and Cu pollution.

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

    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'.

    Given the dependence of our transport system in combustible hydrocarbons that, besides generating serious pollution levels, eventually will become scarce, severely affecting the world economy- it is compulsory to develop non polluting transportation, capable of operating with alternative energies. In the avant-guard of this technological achievement are the competition solar automobiles, that have made great contributions (particularly for the rigorous application of the design for efficiency principles) in the development of the applicable technology to the electric vehicles. Tonatiuh is the first competition solar car built in Mexico. In 1993 Tonatiuh will compete in the Rally Formula Sol in Mexico and in the World Solar of Australia. A superficial comparison of electric vehicles with vehicles equipped with internal combustion motors, demonstrates the great advantages of the first ones, most of all at the light of the current technological advances propitiated by laws that demand them for the sale of electric vehicles. This incipient industry presents a great opportunity for Mexico, since the markets are not saturated and exist large areas of research and development. For improvement of the air quality in Mexico city, the electric vehicle would have a very positive impact, mostly applied to public transportation.

    We review the circularity between estimates of automobile use, fuel consumption and fuel intensity. We find that major gaps exist between estimates of road gasoline, the quantity most often used to represent automobile fuel use in economic studies of transport fuel use, and the actual sales data of gasoline, diesel and other fuels used for automobiles. Significant uncertainties exist in values of both the number of automobiles in use and the distance each is driven, which together yield total automobile use. We present our own calculations for total automobile fuel use for a variety of OECD countries. We comment briefly on the impact of these gaps on econometric estimates of the price and income elasticities of automobile fuel use. (author)

    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.

    An FE analysis procedure was presented to predict the behavior of soil-geogrid interaction under automobile loading. The dynamic interactions between the transverse bars, the longitudinal ribs and the soil were simulated by a system consisting of nonlinear springs, dashpots and masses, to study the deformation properties of the reinforced soil. The equivalent stiffness and damping ratios could be determined with the shaking table. The dynamic responses of a reinforced subgrade were analyzed with the 3D finite element approach. This approach is programmed and applied to analyze the soil-geogrid interaction under dynamic loading. The comparative analysis of the response of the reinforced subgrade and that of the subgrade without reinforcement shows that the geogrid placed at the bottom of the base layer may effectively reduce the accumulative plastic deformation due to the cyclic automobile loading.

    As part of an overall study to evaluate the usefulness of ride quality criteria for the design of improved ground transportation systems an experiment was conducted involving subjective and objective measurement of ride vibrations found in an automobile riding over roadways of various roughness. Correlation of the results led to some very significant relationships between passenger rating and ride accelerations. The latter were collapsed using a frequency-weighted root mean square measure of the random vibration. The results suggest the form of a design criterion giving the relationship between ride vibration and acceptable automobile ride quality. Further the ride criterion is expressed in terms that relate to rides with which most people are familiar. The design of the experiment, the ride vibration data acquisition, the concept of frequency weighting and the correlations found between subjective and objective measurements are presented.

    Obsolete automobiles are the most recycled high-volume consumer product, with a recovery rate of between 75 and 80 per cent by weight. Ferrous scrap metal from old automobiles in North America amounts to about 10 million tons per year. However, each ton of steel that is recovered, produces about 300 kg of automobile shredder residue (ASR), comprised of plastics, rubber, glass, foam, and textiles, contaminated by oil and other fluids. All combined, this represents about 0.3 million tons of waste materials from the 22 shredders in Canada. This amount is likely to increase as the amount of steel in automobiles decreases due to downsizing and weight reduction, emphasizing the need for new resource recovery and application techniques to deal with the ASR problem. This paper describes a number of new initiatives primarily in two areas: separation technologies, ranging from selective disassembly to physical/mechanical/chemical separation processes, and pyrolysis techniques for the recovery of valuable hydrocarbon resources contained in the plastics in the ASR. Recycling of the material into high performance composite materials, such as additives to concrete for increased tensile strength, shrinkage and crack resistance, without adverse effect on other properties such as durability and workability, also received attention. Energy recovery options and engineered landfilling wherein ASR is used as a landfill day cover material, are some other techniques that show considerable promise. In landfill applications the high absorption capacity of ASR for heavy metals such as lead, its high compressibility, erosion resistance, and good traction make it a highly desirable choice for use as day cover material. 25 refs.

    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.

    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.

    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)

En este ensayo, centrado en el tema de la Educación, señalamos los principios básicos que configuran el modelo educativo de la era industrial. Para este fin utilizamos los resultados que Alvin Toffler da a conocer en su libro La tercera ola. Estos principios son: uniformización, especialización, sincronización, concentración, maximización y centralización. Tras destacarlos y mostrar cómo cada uno de estos principios deja su impronta en la educación formal del período industrial, defendemos la tesis de que la Nueva educación nace y se configura en un proceso de desmontaje y sustitución por principios del industrialismo por los nuevos principios de la naciente sociedad post-industrial, también llamada Sociedad del conocimiento.  Abstract. We point out in this article centered on Education the main principles that shape the educational model of the industrial age. Those principles were explained by Alvin Toffler in his book The Third Wave. They are: standardization, specialization, synchronization, concentration, maximization and centralization. After emphasizing them and showing how each one of them leaves its mark in the formal education in the industrial age, we defend the thesis that the new education is originated and configures itself in a process of dismantling and replacement of the principles of the industrialism by the new principles of the raising post-industrial society, also called Society of the Knowledge.

    Full Text Available The lack of integral and modernized design and the saturation of the Barcelona Airport made the remodelling of the old terminal building necessary. The old building elements conditioned the lineal solution in the remodelling. An elevated street forms the backbone of the building which, like the Ramblas in Barcelona, has shops, news stands, etc. Other new elements are the pre-boarding modules and the International terminal. The former have a glazed gallery in their perimeter: a transparent division which allows the separation of the arrival and departure flows. The new terminal rests on four large columns and has double glazing in the entire perimeter

    «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».

Assim sendo, criou-se a filosofia do parto medlcalizado, com rigorosa assepsia e atitudes técnicas, multas vezes desnecessárias, interferindo nesta maravilhosa conquista evolutiva que é o parto normal.

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

    Energy Technology Data Exchange (ETDEWEB)

    Urmetzer, P.; Blake, D. E.; Guppy, N. [British Columbia Univ., Vancouver, BC (Canada)

    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.

    2014-10-20

    We describe an interactive visualization procedure for determining the optimal surface of a special automobile side mirror, thereby removing the blind spot, without the need for feedback from the error-prone manufacturing process. If the horizontally progressive curvature distributions are set to the semi-mathematical expression for a free-form surface, the surface point set can then be derived through numerical integration. This is then converted to a NURBS surface while retaining the surface curvature. Then, reflective scenes from the driving environment can be virtually realized using photorealistic ray tracing, in order to evaluate how these reflected images would appear to drivers.

    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.

    In Japan, automobile and steel engineers are working together for automotive body weight reduction. They are focusing on weight reduction from the point of view of both body structure and material. In order to meet the increasingly severe requirements for weight reduction, aiming at the limitation of the fuel consumption, an expansion in the range of application of HSS is vital. To realize further reduction, joint research by steelmakers and automobile manufacturers will become increasingly important. (authors)

    2000-07-01

    In recent years several recycling and resource recovery technologies have been tested for the challenging task of recycling automobile shredder residues (ASR) with varying degrees of success. ASR is the nonrecyclable residue that remains after recyclable metals are extracted from old automobiles. The use of ASR as a landfill day cover seems to be a viable alternative for this material. Scientific evidence suggests that ASR is capable of acting as a sponge for heavy metals. The absorption capacity of ASR for heavy metal lead was presented along with evaluations for both standard leaching test protocols and dynamic column testing. Compared to soil, ASR has a greater absorption capacity for heavy metals such as lead. ASR also has other desirable features that make it an ideal choice for landfill day cover. For example, ASR provides a stable mat for vehicle traffic, minimizes erosion due to rainfall run off and is less prone to dusting. ASR is also capable of compression to less than 5 cm when overfilled. This conserves landfill volume and allows excavated soil to be used for other purposes. In addition, the use of ASR could prevent contamination of groundwater by preventing the leaching of heavy metals from landfills. 12 refs., 5 tabs., 2 figs.

    2011-01-15

    The aim of this work was developing a hydrometallurgical process to recover metals from automobile shredded residue (or car fluff). Automobile shredded residue (ASR) was characterised by particle size distribution, total metal content and metal speciation in order to guide the choice of target metals and the operating conditions of leaching. Characterisation results showed that Fe is the most abundant metal in the waste, while Zn was the second abundant metal in the fraction with diameter lower than 500 μm. Sequential extractions denoted that Zn was easily extractable by weak acid attack, while Fe and Al required a strong acid attack to be removed. In order to recover zinc from leaching tests were operated using acetic acid, sulphuric acid and sodium hydroxide at different concentrations. Sulphuric acid determined the highest zinc extraction yield, while acetic acid determined the highest zinc extractive selectivity. Sodium hydroxide promoted an intermediate situation between sulphuric and acetic acid. Zn recovery by electro winning using acetic leach liquor determined 95% of Zn electro deposition yield in 1h, while using sulphuric leach liquor 40% yield in 1h and 50% yield in 2h were obtained. Simulation results showed that the sulphuric leaching process was more attractive than acetic leaching process.

    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.

    2012-01-01

    This is a research study based on an analysis which sets out to identify and pinpoint ergonomic and usability problems found in a sample of automobile dashboards. The sample consisted of three dashboards, of three different makes and characterized as being a popular model, an average model and a luxury model. The examination was conducted by observation, with the aid of photography, notes and open interview, questionnaires and performing tasks with users, the bases of which are on the principles laid down by methodologies. From this it was possible to point to the existence of problems such as: complaints about the layout, lighting, colors, available area, difficult access to points of interaction, such as buttons, and the difficult nomenclature of dials. Later, the findings and recommendations presented show the need for a further, deeper study, using more accurate tools, a larger sample of users, and an anthropometric study focused on the dashboard, since reading and understanding it have to be done quickly and accurately, and that more attention be given to the study of automobile dashboards, particularly in the most popular vehicles in order to maintain the standards of usability, and drivers' comfort and safety.

    Aiming at the fatigue and comfort issues of human-machine contact Interface in automobile driving and based on physiological and anatomical principle, the physiological and biochemical process of muscles and nerves in the formation and development of fatigue is analyzed systematically. The fatigue-causing physiological characteristic Indexes are mapped to biomechanical Indexes like muscle stress-strain, the compression deformation of Wood vessels and nerves etc.from the perspective of formation mechanism. The geometrical model of skeleton and parenchyma is established by applying CT-scanned body data and MRI images. The general rule of comfort body pressure distribution is acquired through the analysis of anatomical structure of buttocks and femoral region. The comprehensive lest platform for sitting comfort of 3D adjustable contact Interface is constructed. The lest of body pressure distribution of human-machine contact interface and its comparison with subjective evaluation indicates that the biomechanical Indexes of automobile driving human-machine contact interface and body pressure distribution rule studied can effectively evaluate the fatigue and comfort issues of human-machine contact interface and provide theoretical basis for the optimal design of human-machine contact interface.

    Wetmore, Jameson M

    2015-04-01

    This article explores the attempts in the United States in the 1970s to implement a new paradigm for automobile safety-crashworthiness, the idea that automobile passengers should be protected in the event of a crash. A large number of strategies were proposed, including air bags, seatbelt modifications, mandatory belt-use laws, and ignition interlocks. Many of these did not initially come to fruition, but they did give the automobile safety community a chance to experiment with different ways of distributing responsibilities between automobile occupants, automobile manufacturers, and, to a lesser extent, government agencies. These experiments helped pave the way for the successful implementation of a number of new strategies in the 1980s, 1990s, and 2000s.

  11. 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

    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.

    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.

    Engineering plastics are used in instrument panels, interior trims, and other vehicle applications, and the thermo-mechanical behaviors of plastic materials are strongly influenced by many environmental factors such as temperature, sunlight, and rain. As the material properties change, the mechanical parts create unexpected noise. In this study, the dynamic mechanical property changes of plastics used in automobiles are measured to investigate the effect of temperature. Visco-elastic properties such as the glass transition temperature and storage modulus and loss factors under temperature and frequency sweeps were measured. The data results were compared with the original ones before aging to analyze the behavioral changes. It was found that as the temperature increased, the storage modulus decreased and the loss factor increased slightly.

    2007-01-01

    As point cloud of one whole vehicle body has the traits of large geometric dimension, huge data and rigorous reverse precision, one pretreatment algorithm on automobile body point cloud is put forward. The basic idea of the registration algorithm based on the skeleton points is to construct the skeleton points of the whole vehicle model and the mark points of the separate point cloud, to search the mapped relationship between skeleton points and mark points using congruence triangle method and to match the whole vehicle point cloud using the improved iterative closed point (ICP) algorithm. The data reduction algorithm, based on average square root of distance, condenses data by three steps, Computing datasets' average square root of distance in sampling cube grid, sorting order according to the value computed from the first step, choosing sampling percentage. The accuracy of the two algorithms above is proved by a registration and reduction example of whole vehicle point cloud of a certain light truck.

    1977-12-01

    Chronic exposure to catalytically treated or noncatalytically treated automobile exhaust significantly depressed the spontaneous locomotor activity (SLA) of rats. Exposure to H/sub 2/SO/sub 4/ alone or CO at comparable levels did not alter the SLA. Exposure to noncatalytically treated exhaust resulted in significant reductions in growth rate and food and water intake. However, these effects were not evident in the exposure to catalytically treated exhaust or in the control H/sub 2/SO/sub 4/ and CO exposures. Blood acid-base analyses indicated that exposure to either catalytically treated exhaust or H/sub 2/SO/sub 4/ elicits a metabolic alkalosis, while exposure to CO alone results in a metabolic acidosis. All acid-base parameters were within the normal range several weeks after the termination of exposure.

    This thesis presents a newly developed dynamic model of household automobile transactions within an integrated land-use transportation and environment (ILUTE) modeling system framework. It is a market-based decision-making tool for use by individuals who have to choose between adding new vehicles to a fleet, disposing of vehicles, trading one of the vehicles of a fleet, or do-nothing. Different approaches were used within the model, including an artificial neural network, hedonic price, regression, and vehicle class and vintage choices. The model can also predict the complex activity of individuals' behaviour to become active in the market. An estimation approach was used to incorporate the vehicle type choice model into the main dynamic transaction choice model.

    Morgan, D. T. (Editor)

    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.

    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.

    Although recent progress in automotive technology has reduced exhaust emissions per mile for new cars, the continuing use of inefficient, higher-polluting old cars as well as increasing vehicle miles driven are undermining the benefits of this progress. As a way to address the "inefficient old vehicle" contribution to this problem, a novel life cycle optimization (LCO) model is introduced and applied to the automobile replacement policy question. The LCO model determines optimal vehicle lifetimes, accounting for technology improvements of new models while considering deteriorating efficiencies of existing models. Life cycle inventories for different vehicle models that represent materials production, manufacturing, use, maintenance, and end-of-life environmental burdens are required as inputs to the LCO model. As a demonstration, the LCO model was applied to mid-sized passenger car models between 1985 and 2020. An optimization was conducted to minimize cumulative carbon monoxide (CO), non-methane hydrocarbon (NMHC), oxides of nitrogen (NOx), carbon dioxide (CO2), and energy use over the time horizon (1985-2020). For CO, NMHC, and NOx pollutants with 12000 mi of annual mileage, automobile lifetimes ranging from 3 to 6 yr are optimal for the 1980s and early 1990s model years while the optimal lifetimes are expected to be 7-14 yr for model year 2000s and beyond. On the other hand, a lifetime of 18 yr minimizes cumulative energy and CO2 based on driving 12000 miles annually. Optimal lifetimes are inversely correlated to annual vehicle mileage, especially for CO, NMHC, and NOx emissions. On the basis of the optimization results, policies improving durability of emission controls, retiring high-emitting vehicles, and improving fuel economies are discussed.

    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.

    Full Text Available O objetivo deste artigo é o de estabelecer conexões entre o recente aumento no uso relativo de trabalhadores qualificados (em comparação aos não qualificados e medidas de tecnologia na manufatura brasileira nas últimas duas décadas. Para tanto, utilizamos a intensidade de P&D como proxy para progresso técnico. Encontramos evidências de complementaridade entre tecnologia e trabalho qualificado, que parece mais intensa entre 1994 e 1997. Além disso, quando utilizamos a intensidade de P&D nos Estados Unidos como instrumento para a intensidade de P&D no Brasil, seu impacto sobre a qualificação aumenta substancialmente, o que nos fornece indícios de que a transferência de tecnologia é um dos fatores que explica o aumento do uso relativo de qualificação no Brasil.The main aim of this paper is to investigate the relationship between skill upgrading and measures of technology in Brazilian manufacturing for the last two decades. We use R&D intensity as a proxy for technological change. We find robust evidence of technology-skill complementarity, especially for the period between 1994 and 1997. Furthermore, when U.S. R&D intensity is used as an instrument for Brazilian R&D intensity, its impact on skill demand rises threefold. This provides us with evidence that technological transfer is impacting skill-upgrading in Brazil.

  9. As tecnologias da informação e a exclusão digital

    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.

    Full Text Available O presente trabalho é uma reflexão sobre o discurso jornalístico em um momento de mudança, a partir do advento da tecnologia digital. Essa tecnologia age na identificação de jornalistas e leitores em relação a “o que é o jornal”. A análise da enunciação em torno desse momento no meio jornalístico aponta para um jornal que acaba e um jornal que fica: ou seja, a designação jornal mantém-se em referência a um conjunto determinado de textos em que se destacam as “notícias”, embora a materialidade digital faça (desse objeto (um outro. A análise dessa enunciação e do acontecimento da tecnologia digital na prática jornalística se faz através da metodologia da análise de discurso, com os conceitos de formações imaginárias e interdiscurso, de Pêcheux (1988, bem como da distinção proposta por Orlandi (2001 entre constituição, formulação e circulação do discurso. Verificou-se, com esta análise, que na transferência do sentido de jornal para a materialidade digital funciona a produção de uma identidade corporativa – mais exatamente, o reforço da identidade corporativa que já funciona – sobre esse corpo enquanto imagem (imaginário, que se marca graficamente.

Acreditando que o CTI é uma subcultura do hospital e que os enfermeiros intensivistas compartilham de símbolos e significados que foram desenvolvidos através das interações sociais no contexto da Terapia Intensiva, fui buscar no interacionismo simbólico e na descrição etnográfica a fundamentação teórico-metodológica para o presente estudo. Para compreender o processo de interiorização dos universos simbólicos no CTI, busquei descrever os sistemas temáticos de significados subjacentes às atividades dos enfermeiros intensivistas, através da observação participante, da entrevista etnográfica e da análise documental. Dentre os elementos culturais descritos, foi identificado o mito do saber e da tecnologia. Concluí que os mitos da tecnologia e do saber foram socialmente estabelecidos como estratégia de sobrevivência no cotidiano da terapia intensiva, repleto de riscos e incertezas.

    Full Text Available O trabalho tem como objetivo mostrar a importância do processo de internacionalização de empresas de países em desenvolvimento, que enfrentam a competição global, uma vez que a produção fora do país ajuda a estimular as exportações de matérias-primas, componentes e produtos acabados, sobretudo em setores industriais produtores de bens diferenciados e de maior conteúdo tecnológico. Além disso, a exposição a mercados mais exigentes facilita a incorporação de novas tecnologias e a capacitação de pessoal. Com base nas teorias comportamentais e econômicas que explicam o processo de internacionalização de empresas, foi realizado estudo de caso na empresa Sabó, do setor de autopeças, e uma das poucas empresas nacionais que sobreviveram à abertura econômica do país, a partir de 1990, devido ao seu caráter inovador, que lhe permite competir com as maiores empresas do ramo no mercado internacional. Conclui-se que, quando as empresas possuem um forte ativo, no caso a tecnologia inovadora, as teorias econômicas explicam melhor o sucesso internacional.

    Full Text Available O avanço tecnológico deixou marcas nos mais diversos âmbitos da sociedade, seja no social, politico ou econômico e a narrativa não deixou de acompanhar esses avanços. Narrar sua subjetividade é próprio do ser humano, desde os primórdios, e as mídias surgem como uma nova ferramenta que auxilia na forma como o indivíduo se inscreve e se legitima no mundo. A verdade é que as tecnologias podem ser lidas como mais um espaço de legitimação da produção cultural de indivíduos ditos marginalizados, ou, aos moldes de Gaytri Spivak, subalternos. A narrativa oral urbana dá a oportunidade aos marginalizados de se reinventarem e de mostrarem suas habilidades, sejam elas artísticas, culturais, etc. Este artigo pretende ser uma reflexão acerca da importância da linguagem e do uso das tecnologias e mídias para a valorização de narrativas orais urbanas produzidas em um bairro periférico, a Restinga, 30 km ao sul do centro de Porto Alegre, por indivíduos à margem e que nem por isso deixam de permitir um olhar desde uma perspectiva canônica.

    With increasing automobile ownerships in China, the number of end-of-life vehicles has also rapidly increased. However, the automobile shredder residue generated during the dismantling of end-of-life vehicles in China is not treated properly and has caused great resource waste and environmental problems. In this work, automobile shredder residue from a domestic end-of-life vehicles dismantling company was comprehensively studied through element analysis, combustion heat experiment, proximate analysis, and thermogravimetric analysis. The feasibility of using pyrolysis combined with gasification to treat and recycle automobile shredder residue was investigated. The produced gas, oil, and residue yield was measured and the correlation between their yield and the experimental temperature and ratio of air to automobile shredder residue feed was studied. It is found that when ratio of air and experimental temperature are 1.5 mol kg(-1) and 900 °C, respectively, the heat energy of the gas produced per kilogram treated automobile shredder residue reaches a maximum value of 11.28 MJ. The characteristics of pyrolysis oil and solid residue were studied. The solid residue takes up 4.65%~5.57% of the original end-of-life vehicles weight. This greatly helps to reach the target of a 95% recycling rate.

    2016-03-01

    Full Text Available In the present work, a comparative frictional behaviour of drum brakes and disc brakes in automobiles has been investigated. The influential factors; contact force and friction radius were modeled for the estimation of the friction coefficient for drum as well as disc brakes. The effect of contact force and friction radius is studied with varying conditions of parameters; longitudinal force, caliper force and torque on piston side as well as non-piston side. The numerical results obtained have been compared with the similar obtained from virtual Matlab/Simulink models for drum and disc brakes. The results evidenced that friction radius predominantly affects brake pressure and thus the friction coefficient, also the increase in contact force resulted with decrease in friction coefficient both for drum and disc brakes. Further it has been found that disc brakes exhibit gradual decrease of friction coefficient due to the equitable distribution of braking effort while drum brake presents sudden variations in friction coefficient. It can be revealed that frictional behaviour of disc brake is more consistent than drum brake.

  5. Automobile Shredder Residues in Italy: characterization and valorization opportunities.

    Fiore, S; Ruffino, B; Zanetti, M C

    2012-08-01

    At the moment Automobile Shredder Residue (ASR) is usually landfilled worldwide, but European draft Directive 2000/53/CE forces the development of alternative solutions, stating the 95%-wt recovery of an End of Life Vehicle (ELV) weight to be fulfilled by 2015. This work describes two industrial tests, each involving 250-300 t of ELVs, in which different pre-shredding operations were performed. The produced ASR materials underwent an extended characterization and some post-shredding processes, consisting of dimensional, magnetic, electrostatic and densimetric separation phases, were tested on laboratory scale, having as main purpose the enhancement of ASR recovery/recycling and the minimization of the landfilled fraction. The gathered results show that accurate depollution and dismantling operations are mandatory to obtain a high quality ASR material which may be recycled/recovered and partially landfilled according to the actual European Union regulations, with particular concern for Lower Heating Value (LHV), heavy metals content and Dissolved Organic Carbon (DOC) as critical parameters. Moreover post-shredding technical solutions foreseeing minimum economic and engineering efforts, therefore realizable in common European ELVs shredding plants, may lead to multi-purposed (material recovery and thermal valorization) opportunities for ASR reuse/recovery.

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

    Science.gov (United States)

    Rowe, D. M.; Smith, J.; Thomas, G.; Min, G.

    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.

    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.

    Full Text Available In this paper the authors identify and investigate the key factors which influence intentions to purchase passenger cars among consumers in Pakistan. A questionnaire was developed to check the significance of these key variables identified from previous studies, especially those conducted in the context of automobile purchasing in Asian countries. Faculty members from universities of two major cities in Pakistan were selected at random as respondents for this study. The findings of the study will be useful to both managers in the auto industry as well as policy makers. It will help managers in the auto industry to gain a better understanding of consumer intentions and identify the factors which influence them. Policy makers in Pakistan’s auto sector would benefit from the insights of this study when developing the long overdue Auto Policy. Analysis of the data collected has revealed that the three key factors identified from studies in other Asian countries are also relevant for Pakistani auto consumers.

  9. Keep the driver in control: Automating automobiles of the future.

    Banks, Victoria A; Stanton, Neville A

    2016-03-01

    Automated automobiles will be on our roads within the next decade but the role of the driver has not yet been formerly recognised or designed. Rather, the driver is often left in a passive monitoring role until they are required to reclaim control from the vehicle. This research aimed to test the idea of driver-initiated automation, in which the automation offers decision support that can be either accepted or ignored. The test case examined a combination of lateral and longitudinal control in addition to an auto-overtake system. Despite putting the driver in control of the automated systems by enabling them to accept or ignore behavioural suggestions (e.g. overtake), there were still issues associated with increased workload and decreased trust. These issues are likely to have arisen due to the way in which the automated system has been designed. Recommendations for improvements in systems design have been made which are likely to improve trust and make the role of the driver more transparent concerning their authority over the automated system.

    This lecture introduces a concept of measurement technology with video integration for commercial vehicles. We would like to present DAVIS-CAR, a system for mobile data acquisition. It enables the simultaneous evaluation of video data and test data and consists of mobile as well as of stationary components in a client/server architecture. The product DAVIS-CAR is suitable not only for testing entire vehicles but for external suppliers developing vehicle components or for analysing a person's driving performance. Even for completely stationary systems DAVIS-CAR provides advantages in situations when video data are recorded to get additional information on tests.

    High solid coating is one of the most important environmental friendly coatings, and has been obtained great attention since 70s' last century. For there are high volatile organic compounds(VOCs) in the conventional coatings, which cause both a serious pollution and consume of a plentiful of natural resource, such as petroleum. The development and production of high solid coatings is pressing target for all the countries, especially for China due to our heavy population and short of resources. Based on the requirement, a novel coating with high solid content has been developed in our lab. The solid content of the resin is 80%, compared to the 55% of conversional resin. This coating is characterized by its unique molecular architecture, it is a kind of hyper-branched polymer with uniform distribution of the reactive groups along the molecular backbone, which can react with other chemicals to form a cross-linking structure at high temperature.The coating has a lower viscosity and lower Tg corresponding to its branched structure( scheme 1).This coating has been applied in the automobile finishing. The experimental results indicated that the developed coating presented high performance properties in fastness, mar resistance, and hardness, it also reduced the baking temperature, resulting in a energy saving.

    This article evaluates, by means of multivariate regression, critical factors influencing the collisions of motor vehicles with adult (over 17 years) cyclists that result in fatal injury of cyclists. The analysis is based on the database of the Traffic Police of Czech Republic from the time period 1995-2007. The results suggest that the most consequential categories of factors under study are: inappropriate driving speed of automobile; the head-on crash; and night-time traffic in places without streetlights. The cyclists' faults are of most serious consequence on crossroads when cyclists deny the right of way. Males are more likely to suffer a fatal injury due to a collision with a car than females. The most vulnerable age group are cyclists above 65 years. A fatal injury of a cyclist is more often driver's fault than cyclist's (598 vs. 370). In order to reduce the fatal risk, it is recommended to separate the road traffic of motor vehicles from bicyclists in critical road-sections; or, at least, to reduce speed limits there.

    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.

    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.

  5. The promise of fuel cell-based automobiles

    2003-02-01

    Fuel cell-based automobiles have gained attention in the last few years due to growing public concern about urban air pollution and consequent environmental problems. From an analysis of the power and energy requirements of a modern car, it is estimated that a base sustainable power of $ca$. 50 kW supplemented with short bursts up to 80 kW will suffice in most driving requirements. The energy demand depends greatly on driving characteristics but under normal usage is expected to be 200 Wh/km. The advantages and disadvantages of candidate fuel-cell systems and various fuels are considered together with the issue of whether the fuel should be converted directly in the fuel cell or should be reformed to hydrogen onboard the vehicle. For fuel cell vehicles to compete successfully with conventional internal-combustion engine vehicles, it appears that direct conversion fuel cells using probably hydrogen, but possibly methanol, are the only realistic contenders for road transportation applications. Among the available fuel cell technologies, polymer–electrolyte fuel cells directly fueled with hydrogen appear to be the best option for powering fuel cell vehicles as there is every prospect that these will exceed the performance of the internal-combustion engine vehicles but for their first cost. A target cost of $ 50/kW would be mandatory to make polymer–electrolyte fuel cells competitive with the internal combustion engines and can only be achieved with design changes that would substantially reduce the quantity of materials used. At present, prominent car manufacturers are deploying important research and development efforts to develop fuel cell vehicles and are projecting to start production by 2005.

    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 (maximum 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 international 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-conditioning (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-led 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. (author)

    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.)

  8. Automobile materials competition: energy implications of fiber-reinforced plastics

    1981-10-01

    The embodied energy, structural weight, and transportation energy (fuel requirement) characteristics of steel, fiber-reinforced plastics, and aluminum were assessed to determine the overall energy savings of materials substitution in automobiles. In body panels, a 1.0-lb steel component with an associated 0.5 lb in secondary weight is structurally equivalent to a 0.6-lb fiber-reinforced plastic component with 0.3 lb in associated secondary weight or a 0.5-lb aluminum component with 0.25 lb of secondary weight. (Secondary weight refers to the combined weight of the vehicle's support structure, engine, braking system, and drive train, all of which can be reduced in response to a decrease in total vehicle weight.) The life cycle transportation energy requirements of structurally equivalent body panels (including their associated secondary weights) are 174.4 x 10/sup 3/ Btu for steel, 104.6 x 10/sup 3/ Btu for fiber-reinforced plastics, and 87.2 x 10/sup 3/ Btu for aluminum. The embodied energy requirements are 37.2 x 10/sup 3/ Btu for steel, 22.1 x 10/sup 3/ Btu for fiber-reinforced plastics, and 87.1 x 10/sup 3/ Btu for aluminum. These results can be combined to yield total energy requirements of 211.6 x 10/sup 3/ Btu for steel, 126.7 x 10/sup 3/ Btu for fiber-reinforced plastics, and 174.3 x 10/sup 3/ Btu for aluminum. Fiber-reinforced plastics offer the greatest improvements over steel in both embodied and total energy requirements. Aluminum achieves the greatest savings in transportation energy.

    Automobile shredder residue (ASR) from end-of-life vehicles (ELVs) in Korea has commonly been disposed of in landfills. Due to the growing number of scrapped cars and the decreasing availability of landfill space, effective technology for reducing ASR is needed. However ASR is a complex mixture, and finding an appropriate treatment is not easy on account of the harmful compounds in ASR. Therefore, research continues to seek an effective treatment technology. However most studies have thus far been performed in the laboratory, whereas few commercial and pilot studies have been performed. This paper studies the pyrolysis and gasification-melting of ASR. The pyrolyis characteristics have been analyzed in a thermogravimetric analyzer (TGA), a Lindberg furnace, and a fixed-bed pyrolyzer to study the fundamental characteristics of ASR thermal conversion. As a pilot study, shaft-type gasification-melting was performed. High-temperature gasification-melting was performed in a 5000 kg/day pilot system. The gas yield and syngas (H2 and CO) concentration increase when the reaction temperature increases. Gas with a high calorific value of more than 16,800 kJ/m3 was produced in the pyrolyzer. From the gasification-melting process, syngas of CO (30-40%) and H2(10-15%) was produced, with 5% CH4 produced as well. Slag generation was 17% of the initial ASR, with 5.8% metal content and 4% fly ash. The concentration of CO decreases, whereas the H2, CO2, and CH4 concentrations increase with an increase in the equivalence ratio (ER). The emission levels of dioxin and air pollution compounds except nitrogen oxides (NO(x)) were shown to satisfy Korean regulations.

    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.

  3. Comparison of energy-storage devices for use in future automobiles

    Energy Technology Data Exchange (ETDEWEB)

    O' Connell, L.G.

    1981-06-20

    The Transportation System Research Program of the Lawrence Livermore National Laboratory (LLNL) conducted a study over a four year period to determine which energy-storage devices and their associated propulsion systems are likely to be capable of providing credible alternatives to current type automotive propulsion systems between now and the year 2000. It was found that a complete spectrum of automotive performance levels can be achieved by energy storage automobiles during this time period. These range from automobiles with general-purpose performance equivalent to internal combustion engine (ICE) performance to performance suitable for vehicles with specific missions. These automobiles will likely be more expensive to purchase than their ICE counterparts. Large scale introduction of such vehicles can be constrained not only by the development of energy storage technology, but also by the abailability of the required manufacturing capability and service infrastructure.

    A regulation task which subjected the automobile to a random gust disturbance which is countered by driver control action is used to study the effects of various automobile steering characteristics on the driver/vehicle system. The experiments used a variable stability automobile specially configured to permit insertion of the simulated gust disturbance and the measurement of the driver/vehicle system characteristics. Driver/vehicle system dynamics were measured and interpreted as an effective open loop system describing function. Objective measures of system bandwidth, stability, and time delays were deduced and compared. These objective measures were supplemented by driver ratings. A tentative optimum range of vehicle dynamics for the directional regulation task was established.

    Full Text Available Da aplicação da perspectiva estruturalista ao campo das tecnologias da informação, a adaptação tecnológica passa a constituir um processo contínuo, que acompanha todo o ciclo de vida das tecnologias. No entanto, em alguns estudos, a adaptação continua a ter lugar num período limitado no tempo, terminando pouco tempo após a implantação das tecnologias. Atendendo à importância que o contexto organizacional pode apresentar na utilização das tecnologias, o presente artigo tem como objectivo estudar o papel da identidade organizacional empreendedora na reinvenção contínua das tecnologias da informação nas organizações. Por meio da partilha deuma identidade organizacional empreendedora os indivíduos desenvolvem uma atitude mais proactiva e antecipatória na utilização das tecnologias, o que conduz a reajustamentos contínuos da tecnologia, de encontro às necessidades dos utitizadores e da organização. Para a estimulação desta utilização empreendedora da tecnologia, o artigo avança com três factores essenciais ao desenvolvimento de uma identidade organizacional empreendedora: a liderança autêntica, a cultura de aprendizagem e o feedback dos grupos de interesse. O artigo termina com direcções para futuras investigações.

  10. A life-cycle comparison of alternative automobile fuels.

    MacLean, H L; Lave, L B; Lankey, R; Joshi, S

    2000-10-01

    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. The attractiveness of direct injection engines depends on their being able to meet strict emissions standards without losing their greater efficiency. Biofuels offer lower GHG emissions, are sustainable, and

    Full Text Available Existe um novo relacionamento entre o homem e a informação disponível no mundo hoje – e a tecnologia tem um papel a desempenhar neste contexto. A educação pode ser beneficiária deste novo momento da história humana, se puder se valer das tecnologias de informação e comunicação, já disponíveis, para a concepção e implementação de um novo modelo pedagógico, que privilegia a conversão de informação em conhecimento, além de suportar o desenvolvimento de competências e de potencial humano. Entendidas assim, as tecnologias da inteligência (ou de apoio ao desenvolvimento cognitivo são, na verdade, tecnologias da aprendizagem. Os trabalhos pioneiros de Vannevar Bush em aparatos tecnológicos de tratamento da informação - associados a modelos de pensamento e cognição – e aprimorados pelos seus seguidores, serão os meios de realização de tal modelo inovador. There is something new in the relationship between man and the information that is available to him in the present world (last sixty years – and technology has had, and continues to have, a major and structuring role in bringing about and sustaining this new fact.

    2003-12-01

    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".

  7. Cinema e feminismos entre poética e devir: por uma tecnologia engendrada

    Directory of Open Access Journals (Sweden)

    Fernanda Capibaribe Leite

    2015-12-01

    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.

    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.

    Using reflective near infrared sensor and voice record-reproducing assembly, the present article studies the voice anticollision-prompting device for backing an automobile. If there is a man or an object within a certain distance behind the backing automobile, part of the infrared signal will be reflected by the man or the object, and received by the photosensitive tube installed with a transmitting tube, and transformed to a similar frequency electric signal. The electric signal will be amplified, demodulated, and shaped by the circuit of module. After comparing and processing, the control signal will be output, which controls the work of voice record-reproducing assembly, and reminds the driver that there is a man or an object behind the backing automobile. With both the near infrared sensor and voice record-reproducing assembly being integrated, the distance-warning device has the advantages of low costs, simple wiring, strong anti-detonation ability, precise measuring, and working stability. It is suitable for being installed and used on the automobile.

    This report projects to the year 2025 the total number of automobiles that would be owned by American households, (total ownership) and the total number of miles that these vehicles would be driven per day (total use) given certain assumptions about the future of U.S. society. These assumptions relate to demographic, economic, and geographical attrributes of U.S. society that are relevant to the automobile. The impacts of these assumptions were analyzed via a set of projection models which explicitly recognize the relationship between these particular attributes of society and the automobile. Part I presents an overivew of the research and Part II the results. The methodology used to generate the projections is discussed in some detail in Part III. In a base case projection the number of automobiles and average daily travel of Americans double by 2025 due to increases in populaion, headship rates (households per population), and incomes. economic variables account for about half of this increase as indicated by a no economic growth projection in which ownership and daily travel increase just over 40% and 50%, respectively. Other projections explore the effects of differing assumptions regarding rates of household formations, population growth, and income growth. Model projections suggest that changed work schedules and the re-emergence of cities as growth areas will have only slight impacts on future travel and vehicle ownership.

  7. Thermal energy storage for the Stirling engine powered automobile. Final report

    Energy Technology Data Exchange (ETDEWEB)

    Morgan, D T [ed.

    1979-03-01

    A detailed design of a thermal energy storage (TES) system for use with the Stirling engine as an automotive power system has been developed. The gravimetric and volumetric storage densities are competitive with electric battery storage systems. The TES/Stirling engine system 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 developed in this study 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 (approx. 10 miles or less) and liquid fuel carried onboard the vehicle used for long-duration trips (as in current automobiles). The dual-mode approach permits an automobile with the convenience and flexibility of current automobiles while offering the potential of 50% savings in the consumption of premium liquid fuels for automotive propulsion in the United States. Relative to the TES-only vehicle, the dual mode approach also reduces the TES cost significantly because of the much smaller TES capacity required.

    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

The evaluation of the renal function markers show that, there were significant increases in the mean serum concentration of creatinine, urea, and uric acid in the study group compare to the control subjects (P 0.05. Conclusion: Findings from this study show that blood lead level is high among automobile repairers above CDC recommended level for adults. This high blood lead level among automobile repairers may be responsible for raised levels of renal markers which may eventually lead to their renal damage.

    Full Text Available A la vez que produce múltiples formas de violencia socioeconómica (desempleo estructural, precariedad, pobreza, el capitalismo neoliberal intenta evacuar cualquier tipo de reacción antisistémica, condenando la violencia. Ante estos procesos emergen en Europa nuevas formas de protesta que toman distancia del militantismo tradicional. Mediatización, teatralización, espíritu festivo, rechazo a la teorización ideológica y a la violencia: en cierto sentido, se trata de una nueva "estética" del militantismo. ¿En qué medida esta postura puede, paradójicamente, ser funcional a la consolidación del modelo neoliberal? La presente comunicación se propone reflexionar, por un lado, acerca de la legitimidad de la violencia como modalidad del diálogo político y, por otro, sobre los límites del nuevo militantismo "no violento" en relación con las contradicciones intrínsecas de la ideología neoliberal.Palabras clave: Violencia, militantismo, protesta, capitalismo, neoliberalismo___________Abstract: Neoliberal capitalism produces socio-economic violence (structural unemployment, precariousness, poverty, but its discourse condemns the violence and tries to prevent any anti-capitalist reaction. In such context, new forms of social protest are spreading in Europe and distance themselves from traditional activism. Mediatization, dramatization, festive atmosphere, refusal of violence and of any ideological theorization: in some way, it is a new "esthetics" of activism. This paper intends to explain why this posture can paradoxically strengthen the neoliberal model. It analyzes the choice of violence as a legitimate tool of the political "dialog" as well as the limits of new "no violent" activism in relation with the contradictions of neoliberal ideology.Keywords: Violence, activism, social protest, capitalism, neoliberalism

A presente revisão analisa a aplicação dos conceitos clássicos sobre consumismo às práticas recentemente identificadas no campo da saúde, como o fenômeno da cibercondria. O desafio teórico se refere à dificuldade de extrapolação das perspectivas econômicas do consumismo às questões do auto-cuidado no contexto das tecnologias de informação e comunicação (TICs.

Conclui-se que a saúde é consumida como vitalidade decomposta em artefatos de comercializar no contexto de uma nova bioeconomia - não mais ligada à idéia de emulação e posse, e sim a novas formas de perceber-se e cuidar-se perante múltiplos riscos e novas definições do que é ser humano.

    Full Text Available El proceso de formación de bloques regionales iniciado a mediados del siglo XX ha dado lugar al desarrollo de una práctica política denominada regionalismo; práctica asumida por la mayoría de los Estados del mundo a su tiempo, aunque comenzó a manifestarse inicialmente en Europa. La Unión Europea es el antecedente más acabado de regionalismo en tanto que Mercosur, aun es incipiente. En conjunto el bloque conforma una región, pero una región que se distingue de otras por sus componentes, por su estatus político, por la legitimidad de las acciones, por el alcance territorial de las políticas, entre las principales distinciones. Por tratarse de agrupaciones de Estados, el territorio, las fronteras y el poder político, intervienen en su conformación, ya que esos elementos son constitutivos del Estado. No obstante esta particularidad, ese proceso de regionalización esta dando lugar a una nueva territorialidad, porque la regionalización contiene un principio de integración y en conjunto ambos presuponen la existencia de políticas integracionistas o bien regionalistas. Estas políticas han cambiado. En esta presentación se explica por que constituyen nuevas territorialidades, a partir de la comparación del proceso de formación del Estado moderno y el de formación de bloques regionales, centrando el análisis en el territorio del Mercosur. Complementariamente se aborda la práctica regionalista subnacional de Argentina, asociada a la formación Mercosur. El territorio ampliado y compartido desde la perspectiva económica, es la variación más notable y sustancial asociado a esos procesos. También la creación de regiones subnacionales funcionales a los bloques regionales, tales como la región patagónica.

    2000-06-01

    This paper discussed the role that religious institutions have in delivering the message of personal responsibility in the matter of climate change. Private automobiles are large contributors to greenhouse gas (GHG) emissions in North American, where choice and operation of the personal automobile is entirely within personal discretion. It appears that economic and enlightened self-interest arguments are inadequate to motivate behavioural changes that would reduce individual GHG emissions. The author suggested that we need to expand our understanding of neighbourhood to the globe and that since most North Americans admit to religious sentiment, the religious principle of love for neighbour should be a strong motivation for people to make changes in lifestyle such as choosing to drive smaller cars, to drive less and at lower speeds. 31 refs.

    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.

    Science.gov (United States)

    Knibbs, Luke D; de Dear, Richard J; Morawska, Lidia

    2010-05-01

    We alternately measured on-road and in-vehicle ultrafine (automobiles and ventilation settings, a positive linear relationship was found between outdoor air flow rate and I/O ratio, with the former accounting for a substantial proportion of variation in the latter (R(2) = 0.81). UFP concentrations recorded in-cabin during tunnel travel were significantly higher than those reported by comparable studies performed on open roadways. A simple mathematical model afforded the ability to predict tunnel trip average in-cabin UFP concentrations with good accuracy. Our data indicate that under certain conditions, in-cabin UFP exposures incurred during tunnel travel may contribute significantly to daily exposure. The UFP exposure of automobile occupants appears strongly related to their choice of ventilation setting and vehicle.
