    Full Text Available Motivados por la importancia del ruido como riesgo laboral en las actividades productivas de la Carpintería de Aluminio "Tomás Alvarez Breto" decidimos realizar un control audiométrico periódico de estos trabajadores con la finalidad de determinar el grado de exposición de los mismos y establecer las recomendaciones más importantes para su protección. Nos propusimos como objetivo determinar el grado de afectación auditiva por ruido en los trabajadores expuestos al riesgo, para lo cual se cuantificaron los niveles de ruido existentes en los diferentes puestos de trabajo, se confeccionaron las historias clínicas y se realizó un examen otoscópico y una prueba audiométrica en ambos oídos para definir el daño acústico y la presencia de hipoacusia profesional en los obreros estudiados. Al concluir el estudio pudimos comprobar que el ruido constituía un contaminante de gran importancia en esta industria. Este riesgo laboral se encontraba por encima del nivel de seguridad de 85 db(A en 9 de los 13 departamentos con que cuenta el centro y ha afectado la salud de los trabajadores ya que existían 77 casos (78,5% de hipoacusia atribuible al ruido y un gran número de trabajadores (30,6% expuestos a elevados niveles de ruido innecesariamente por la naturaleza de su labor. Por todo esto recomendamos tomar medidas que reduzcan el nivel de ruido en los puestos de trabajo donde existían niveles superiores a los permitidos, exigirse el uso de los medios de protección auditiva en los trabajadores expuestos y cumplirse estrictamente con los exámenes médicos preventivos, incluyendo las pruebas audiométricas anualmente.Motivated by the importance of the noise like labour risk in the productive activities of Aluminium Carpentry Tomas Alvarez Breto we decide to carry out a control periodic audiometric of these workers with the purpose of to determine the degree of exhibition of the same ones and to establish the most important recommendations for

    Full Text Available RESUMEN: En el siguiente artículo se tratará de reflejar la experiencia en un aula de Educación Primaria para acercar a los niños la figura de Claudio Rodríguez y centrarnos en un comentario de su poema «Al ruido del Duero». El colegio elegido es el «Arias Gonzalo», de Zamora. Los niños participaron activamente a la hora de aportar ideas y de comentar el texto. Claudio Rodríguez se sentía fascinado y profesaba un gran amor a su tierra, a sus costumbres y al río Duero. Consideraba que los valores más relevantes del ser humano eran la sencillez, la solidaridad y la fraternidad y deseaba unirse y fundirse, primero, con el entorno natural y, después, con los hombres. En mi opinión, la respuesta de los alumnos fue positiva, ya que captaron la esencia de los versos y demostraron, con su colaboración, que los elementos usados para motivarles habían servido. Lo dejaron patente en las cartas, dibujos y poemas que realizaron posteriormente.ABSTRACT: The following article will try to show a commentary on the poem «Al ruido del Duero» by Claudio Rodríguez, from Zamora. The school which was chosen is called «Arias Gonzalo»; it is in Zamora too. The pupils took part actively and their ideas contributed to comment the text. Claudio Rodríguez was fascinated and professed huge love for the place where he was born, the customs of his province and The Duero River. He believed that the most important human values were simplicity, solidarity and brotherhood. First of all, he wished to be bound to nature. As far as mankind is concerned, he always desired to be joined together. In my opinion, the pupils answered positively and they understood the essence of the verses. They all proved that the elements for motivating them were useful. Then, they showed it clearly by drawing pictures, writing letters and poems.

    Full Text Available The aim of this study was to measure the frequency of hearing loss in a sample of typical public high-school students exposed to recreational noise, and determine associated risk factors. The sample was made up of 214 teenagers from a high-school in Mexico City; subjects were selected randomly per strata. We applied a questionnaire to identify risk factors for hearing loss and performed a battery of audiologic tests consisting of otoscopy, tympanometry, and pure-tone audiometry. The mean age of the sample was 16 ± 1.07 years; 73% were male and 27%, female. Hearing loss was found in 21% of students. The main hearing loss-related risk factor was exposure to recreational noise: frequent attendance at discotheques and pop-music concerts; use of personal stereos; and noise exposure in school workshops. The high frequency of hearing loss in high school students from one Mexico City school (nearly one fifth of the sample was found to be related to noise exposure mainly during recreational activities.El objetivo de este estudio fue medir la frecuencia de alteraciones auditivas en una muestra de escolares de educación media superior expuestos a ruido recreativo y determinar algunos factores de riesgo asociados.

    Full Text Available En el artículo se informa sobre un grupo de artefactos arqueológicos singulares hechos de varios materiales como piedra, hueso, madera, metal y barro que pudieron ser usados como herramientas sonoras, pero no son muy conocidos ni se habían estudiado formalmente. Su función y uso originales se desconocen, pero los artefactos sonoros que se han examinado directamente pueden producir sonidos extraordinarios que se asemejan a los de algunos animales y de fenómenos de la naturaleza como el viento. Los más sencillos morfológicamente se pueden tocar dentro de la boca. Por el tipo de mecanismo sonoro y las señales que generan funcionan como generadores de ruido bucales. Morfológicamente, muestran dos perforaciones cara a cara y una cámara resonadora y de caos entre ellos. En este documento se proporciona la información disponible sobre los generadores de ruido bucales antiguos y contemporáneos que se han encontrado. Se aplica un método de análisis de aerófonos antiguos, mismo que ya se ha complementado y aplicado en más de sesenta estudios originales, incluyendo una tesis. En general, se indican las principales características organológicas, acústicas y posibles usos de los generadores de ruido bucales que fueron identificados y analizados por el autor. El análisis comparativo de los sonidos complejos y variables en el tiempo se realiza con espectrogramas y se dan estimaciones de algunos parámetros acústicos básicos como presión sonora (en dB y potencia acústica radiada máxima (en Watts. Los generadores de ruido bucales mesoamericanos conocidos provienen de varias zonas como las del Golfo y del Occidente, pero los últimos identificados son de las zonas de San Lorenzo Tenochtitlán, Veracruz y de San Juan Raya, Puebla.

    Full Text Available This article gives a general account of the noise problem in air conditioning systems. This problem causes grave concern to the technicians owing to its influence on the comfort of the buildings concerned. The acceptable levels of noise are discussed, also their codification into general specifications. Methods are given to test whether a given installation satisfies such noise specifications, and the means that are usually adopted to prevent air conditioning noise from extending into inhabited rooms. The study of the limitation of noise to a comfortable level depends both on the noise specifications and the actual design of the installation. Scale «A» is utilised in connection with the specifications, and the sound spectral curves are part of the design technique, which enables to obtain the cheapest design for the same level of comfort. The designer needs the fullest cooperation of the manufacturers, who should supply him with detailed accoustical data about the equipment. This applies both to installations that will produce noise and to the material that is meant to absorb it.Se expone en este artículo una idea general del problema del ruido en instalaciones de aire acondicionado, problema que preocupa hondamente en los medios técnicos correspondientes, por su gran influencia en el confort de los edificios. Se dan las cifras de niveles de presión sonora admisibles, recomendables para un Pliego de Condiciones, y el procedimiento para comprobar si las instalaciones terminadas lo cumplen, así como los medios normalmente utilizados para evitar la emisión de ruido a los locales habitados. Para el estudio del confort sonoro se recomienda tener en cuenta, tanto en el Pliego de Condiciones (mediante el empleo de la escala «A» como en el estudio de la eliminación de ruidos, al proyectar la instalación (mediante las curvas espectrales que se indican, no solamente el nivel sonoro global, sino, de acuerdo con la tendencia mundial, el espectro

    Full Text Available Con la hipótesis de que el ruido puede ser nocivo no solamente para el órgano de la audición sino también para el de la fonación, procedimos a estudiar un grupo de 50 trabajadores de un supermercado localizado en un área con alta exposición ambiental al ruido (Cooperativa Cafetera debido a su cercanía al antiguo aeropuerto de la ciudad de Medellín; el otro grupo, compuesto también por 50 Individuos, fue estudiado en el supermercado de Almacenes éxito de El Poblado que tiene baja exposición. Los participantes fueron escogidos al azar de listas de nómina. Se midió Intensidad total de ruido mediante dosimetrías y análisis de frecuencia en diferentes lugares de ambos sitios, durante varias horas del día, todos los días de una semana. En el supermercado expuesto se encontraron Intervalos de ruido de 98 a 105 decibeles (dBy las frecuencias acumuladas fueron superiores a 77 dB; en cambio, para el no expuesto estas cifras fueron 49 a 56, y 70 dB, respectivamente (P<0,0001 . No hubo variaciones Importantes durante las horas del día, ni de un día a otro. En la Cooperativa Cafetera los únicos eventos que producen ruido superior a 85 dB (considerado el máximo para evitar da no auditivo, son el paso de aviones, la sierra cortadora y el molino de carne. No hubo diferencia significativa en la patología otorrinolaringológica general entre los dos grupos. Se diagnosticó patología foniátrica en 8 casos en el grupo expuesto y en 1 en el no expuesto (P<0,05; ésto ayuda a confirmar que 70 dB es el limite superior de ruido ambiental permisible para evitar la ocurrencia de patología de la voz. Creemos que estos límites máximos para prevención de patología foniátrica deben ser definidos por ley y recomendamos varias estrategias para enfrentar el ruido ambiental.

    Electrochemical noise is one of the methods of analysis used to interpret the phenomenon of corrosion. It has a number of advantages over other methodology types including its simplicity, its low cost and the fact that it does not disturb the system. This methodology appears to be effective together with other techniques in metal-electrolyte systems. In this case the technique is applied on its own on commercial anti-corrosion paints for which no information is available from other techniques. The main result of this study reveals the effectiveness of the noise resistance parameter, which had already been tested in the lab, when it is used to explain how the paint system behaves in industry.

    Full Text Available Background: Noise is an environmental pollution agent to which a high percentage of the urban population, as well as residents living around important sources of noise, are exposed.Methods: A cross-sectional study was carried out to measure the perception of noise of the residents living in the area of the bay of Pasaia (Guipuzkoa, Spain. 351 dwellings were randomly selected. A structured questionnaire was used to gather information about the respondent self-perception of annoyance and sensitivity to noise. The sound pressure levels were estimated using a model that took into account the main characteristics of the different sources of noise.Results: 37.5% of the sample reported to be annoyed by noise. The interviewees declared that the main sourceof annoyance was the traffic (60% followed by the activity in the harbour (24%. The annoyance attributed tonoise was not correlated with the estimated sound level, but with the level of sensitivity to this physical agent(r=0.36; pConclusions: The relationship among the degree of annoyance caused by noise, the sensitivity to noise, the sound levels and other social and demographic variables show a very interrelated and complex phenomenon. The fact that half of the population had taken any measure to protect them from noise could have mitigated the percentage of people that declare to be annoyed by noise.Fundamento: El ruido es un agente de contaminación ambiental al que esta expuesto un porcentaje elevado de la población urbana, así como la residente en el entorno de focos emisores importantes.

    Full Text Available Uno de los recursos estratégicos postmodernistas por excelencia es el espectro electromagnético, pero su potencialidad depende en alto grado de la atenuación de los ruidos bien sean de origen natural como artificial, si a lo anterior le sumamos el desarrollo acelerado de las telecomunicaciones en el mundo y en Colombia, como resultado de la liberalización del sector, se plantean nuevos y exigentes retos, como el de diseñar permanentemente redes dentro de un ambiente donde cada operador debe garantizar la compatibilidad al interior de su red y la compatibilidad con otras ajenas. Para evitar conflictos técnicos entre operadores y garantizar una buena calidad de los servicios a los usuarios, es de vital importancia, diseñar las redes de acuerdo con las normas establecidas sobre los niveles de ruidos aceptados, dependiendo del tipo de red. En este artículo se analiza el ruido en las redes teniendo en cuenta las exigencias de los organismos internacionales, sobre todo la UIT, para que sirva de base y de referencia a los ingenieros encargados actualmente de los diseños de redes, compra o fabricación de equipos de telecomunicaciones y especialmente de telefonía, esto es especialmente importante después del ingreso de Colombia a la Organización Mundial del Comercio, OMC, en virtud del cual estamos obligados a exigir y proporcionar equipos y servicios de acuerdo con las recomendaciones internacionales.

    2009-01-01

    Full Text Available Introducción: El estrés es la condición que resulta cuando las personas y el medio ambiente interaccionan y lleva a la persona a una percepción alterada, real o imaginaria, entre las exigencias de una situación por un lado y sus consecuencias sociales, biológicas, psicológicas o de recursos. Los estímulos estresantes pueden ser mentales, fisiológicos, o físico-anatómicos1. En el caso particular de los odontólogos, no existe suficiente información en la literatura internacional en relación a los efectos que tiene en ellos la exposición al ruido producido por el instrumental necesario para llevar acabo los tratamientos. Método: Se realizó un estudio descriptivo y comparativo, con la finalidad de evaluar el nivel de percepción de estrés resultado de la exposición al ruido de un grupo de 45 estomatólogos. Todos los sujetos, contestaron una encuesta auto-aplicada sobre percepción de ruido originado por el uso de equipos que ocasionan estímulos detonadores de estrés. Este instrumento también incluyó preguntas sobre características y ambiente laboral. Los estomatólogos se clasificaron según su nivel de percepción de ruido en aquellos con bajo (90 dB de exposición. Estos grupos también se compararon en relación a la percepción de estrés. Resultados: El promedio de la edad y la antigüedad laboral de los sujetos estudiados fue de 41±8.4 y 15.9 ± 8.7 años, respectivamente. El 58%, mencionaron trabajar solo un turno y 42% trabajaban en los turnos matutino y vespertino. El 44% de los encuestados manifestaron percibir la intensidad del ruido al interior del consultorio como medio, el 40%, manifestó percibirlo como bajo, y el 13.3% dijo que éste era alto. Los valores promedio del nivel del ruido en decibelios, fueron significativamente mayores en los odontólogos generales al compararlos con los especialistas en odontología (t=-4.9, p 90dB/8 horas y los que refieren percibir el ruido como más intenso al compararlos

    Full Text Available Introducción: Las técnicas de evaluación de riesgos laborales se llevan a cabo por diferentes procedimientos, a través de las aplicaciones de métodos normativos del cumplimiento de los parámetros asociados con las mediciones de los umbrales de daño a la salud del hombre. Sin embargo, no se tienen en cuenta los principios básicos de seguridad, que incluyen las experiencias de buenas prácticas en industrias de altos requisitos de seguridad y disponibilidad. Objetivos: El objetivo de este artículo es proponer un método bajo el enfoque de defensa en profundidad para evaluar los riesgos laborales por ruido en la Central Termoeléctrica (CTE de 100 MW. Material y Métodos: Se aplicó la técnica de entrevistas a técnicos y especialistas en seguridad y salud del trabajo, así como tecnólogos para explorar los elementos que tomaban en cuenta en la evaluación de los riesgos laborales por ruido, y se realizó la consulta a especialistas para precisar los elementos que debían formar parte de los aspectos de seguridad de acuerdo al método propuesto. Además Se realizó la evaluación de los riesgos laborales por ruido de acuerdo a dos metodologías implementadas con anterioridad y la propuesta. Resultados: Se muestran de acuerdo a las tres metodologías. Se determinó que la generación de ruidos no es un aspecto significativo a tener en cuenta, para la metodología 1, se evidenció una dispersión del nivel sonoro, con tendencia estable a los valores máximos en determinadas áreas según la Norma Cubana de ruido, para la metodología 2 mientras que para la metodología 3, los aspectos de seguridad evaluados negativamente por cada escalón, son los que se requieren tomar medidas correctivas dirigidas a modificar los ítems calificados negativamente a positivos para elevar el nivel de seguridad. Conclusiones: La evaluación empleando escalones de defensa en profundidad aplicado a los riesgos laborales posibilita un análisis con el enfoque

    Full Text Available The most important difficulty to use electrochemical noise measurement resides in the interpretation of the experimental data. In the literature, three different main approaches have been proposed for processing the experimental records: the statistical, the spectral and the Chaos-Theory based methods. The purpose of this work is to introduce an alternative tool to analyse electrochemical noise: the wavelet transform. It has been found that this tool could be especially usefully to distinguish localised and uniform corrosion processes that are developing simultaneously. To show that, a current noise record corresponding to working electrodes suffering from both kind of corrosion process is analysed by means of the wavelet transform. These results are compared with the ones coming form the Fourier. In addition, a brief theoretical description of the tool is presented and some applications in the field of the industrial monitoring are suggested.

    Full Text Available En este trabajo se propone un esquema para la reducción de ruido gaussiano online basado en wavelet con ventanas deslizantes para ser utilizado en señales industriales. Este tipo de técnicas se utilizan cuando la señal debe ser tratada a medida que se obtienen las muestras, funcionalidad necesaria en aplicaciones con requerimientos de tiempo real, por ejemplo en sistemas SCADA. El algoritmo introducido en el presente trabajo se diferencia de algoritmos similares en que: en primer término utiliza una selección adaptativa del umbral basada en NeighShrink; adicionalmente reutiliza en lo posible los coeficientes wavelet calculados en pasos anteriores para el procesamiento de cada punto; finalmente utiliza la wavelet Haar en lugar de otros filtros de mayor complejidad computacional. Para la comprobación experimental del nuevo esquema se utilizó un conjunto de señales sintéticas introducido por Donoho y Marron, complementadas por señales adquiridas en procesos reales de plantas industriales. Las pruebas realizadas revelan que el algoritmo propuesto mejora la reducción de ruido online respecto a esquemas similares reportados anteriormente y es computacionalmente menos complejo.

    Full Text Available La propuesta que aquí se presenta es producto de una investigación doctoral antropológica recién concluida titulada “La naturaleza sonora de la vida urbana. Ruido, convivencia y conflicto por el espacio sonoro en la Ciudad de México”, cuyo objeto general de estudio ha sido el análisis del fenómeno del ruido más allá de su dimensión estética, es decir, como construcción social producto de la interrelación de factores espaciales, demográficos, psicológicos, culturales e históricos, definidos por el modo de vida urbano. En este marco de reflexiones, el análisis del proceso de adaptación en tanto fenómeno fundador de las relaciones ambientales constituye una prioridad, pues permite comprender los procesos de ajuste y desajuste entre el entorno urbano y sus habitantes. Específicamente, al hablar del ruido se pretende conocer las diversas maneras en que esta relación se ha desarrollado no sólo por vía de la atrofia sensorial, sino a través de diversas técnicas de construcción de la vida cotidiana, donde alcanzar la normalidad es una situación patológica de la vida en las grandes ciudades como México.

Nos hemos centrado en los primeros números que salen a la calle tras el acontecimiento, poniendo especial atención en las informaciones existentes sobre las reacciones tras el atentado, o sobre la identidad de los autores. El análisis de estos temas nos ha permitido observar fenómenos como el ruido y el silencio en la transmisión de la información, cuestiones que nos ofrecen una interesante reflexión sobre la relación que existe entre la ideología de los medios y su percepción del mundo. Con el artículo, por tanto, ponemos de manifiesto dos talantes ante la crisis, dos talantes que están influyendo sobremanera en la percepción del acontecimiento histórico en los medios de comunicación. _____________________ABSTRACT:The article we present intends to analyse the strategies used by El Alcázar and Informaciones in dealing with the murder of Carrero Blanco. We have focused on the first issues that got out to the streets after the event, paying special attention to the existing news concerning the reactions after the assault or about the authors identity. The analysis of these subjects has allowed us to observe phenomena like the noise and the silence within the transmission of the information, issues that offered an interesting reflection on the relation that exists between the media ideology and its world perception. Through this article, therefore, we show two ways of acting in front of the crisis, two ways that are affecting the historical event perception in the media.

    It is well known that α-Al2O3 forms very hard, highly insulating, smooth films. There is demand for the use of such films instead of conventional hard, smooth films; For example, industrial rollers such as calendering rollers etc. are always required to have a harder and smoother surface than conventional rollers. Therefore, this work investigated the specification of α-Al2O3 films, e.g., their wear resistance and chemical stability, using various tests. This paper also discusses whether α-Al2O3 film can take the place of Cr plating film as a hard, smooth film by comparing their wear resistance and chemical stability.

    Steam silencers have been placed on the power units regulation system of the Cerro Prieto geothermal field, but not where the steam-pipes vent high-pressure steam (rupture disks). Moreover, the power-unit silencers are large and their abilities to reduce noise depend on an external, uncontrollable factor: pores sizes in the volcanic rocks they are made of. Thus a compact, economic and relatively easy to construct metallic silencer was designed to be used at several points of dry-steam venting to minimize the noise. The design was based on orifice-plate equations and a prototype was constructed and tested. It proved capable of reducing noise by 30 decibels for atmospheric discharges of primary steam at operating pressures. The size of the silencer can be adjusted to the particular needs of each vent case. [Spanish] En el campo geotermico de Cerro Prieto solo existen silenciadores de vapor en el sistema de regulacion de las plantas generadoras, pero no en los sitios de desfogue de vapor a alta presion en los vaporductos (discos de ruptura). Ademas, los silenciadores de las plantas son muy robustos y su capacidad de reduccion del ruido depende de un factor externo no controlable, como es el tamano del poro de la roca volcanica con el que estan construidos. Por lo tanto, se diseno un silenciador metalico compacto, economico y relativamente facil de fabricar, para utilizarse en diversos puntos de descarga de vapor seco a fin de minimizar el ruido. El diseno se realizo con base en las ecuaciones de la placa de orificio. Se construyo un prototipo cuyas pruebas demostraron que es capaz de reducir el ruido hasta en 30 decibeles, al descargar desde la presion de operacion de vapor primario hacia la presion atmosferica. Las dimensiones del silenciador pueden ajustarse a las necesidades particulares de cada caso de desfogue.

    Full Text Available The concentration of chloride ions and the partial pressure of CO2 play an important role in the degradation of low-carbon steels used for the construction of pipelines in oil and gas industry. In order to evaluate the susceptibility of carbon steel API 5L X42 to pitting corrosion electrochemical noise and linear polarization resistance measurements were carried out in aqueous solutions containing chloride ions and CO2. The concentration of chloride ions was varied between, 10000 and 18000 ppm, and the CO2 partial pressure between 10 psi and 18 psi. Experimental results pointed out that the formation of protective layer, consisting mainly of FeCO 3, depends on the partial pressure of CO2 in the system. Nevertheless, the stability of this layer was considerably affected by increasing the concentration of chloride ions causing that localized corrosion has taken place in some areas of the surface of API 5L X42, which were detected by electrochemical noise echnique.La concentración de iones cloruro y la presión parcial de CO2, tienen un papel importante en el proceso de degradación de los aceros de bajo carbono empleados en la construcción de líneas de transporte en industrias petroleras.

Los resultados indican que la formación de una capa protectora, constituida principalmente por FeCO3, depende de la presión parcial de CO2 del sistema. No obstante, la estabilidad de dicha capa es afectada significativamente por el aumento de la concentración de iones cloruro, que producen fenómenos de corrosión localizada en algunas áreas de la superficie del acero API 5L X42, los cuales fueron detectados por la técnica de

    In a PWR type reactor, the neutron noise increases gradually its amplitude because of boron dilution. In a KWU type reactor, this phenomena is more intense and might cause to descend the operating power along the cycle. It is likely that this behavior will occur in the EPR prototype. Noise amplitude analysis is made in this work by using advanced statistics techniques, results are: criteria for the choice of the best sensor to be used in the Reactor Safety Logic; and early detection of sensor malfunctions.

    This chapter addresses past, ongoing, and short (to 2010) and medium-term (to 2030) future actions that can be taken to mitigate GHG emissions from the manufacturing and process industries. Globally, and in most countries, CO{sub 2} accounts for more than 90% of CO{sub 2}-eq GHG emissions from the industrial sector (Price et al., 2006; US EPA, 2006b). These CO{sub 2} emissions arise from three sources: (1) the use of fossil fuels for energy, either directly by industry for heat and power generation or indirectly in the generation of purchased electricity and steam; (2) non-energy uses of fossil fuels in chemical processing and metal smelting; and (3) non-fossil fuel sources, for example cement and lime manufacture. Industrial processes also emit other GHGs, e.g.: (1) Nitrous oxide (N{sub 2}O) is emitted as a byproduct of adipic acid, nitric acid and caprolactam production; (2) HFC-23 is emitted as a byproduct of HCFC-22 production, a refrigerant, and also used in fluoroplastics manufacture; (3) Perfluorocarbons (PFCs) are emitted as byproducts of aluminium smelting and in semiconductor manufacture; (4) Sulphur hexafluoride (SF{sub 6}) is emitted in the manufacture, use and, decommissioning of gas insulated electrical switchgear, during the production of flat screen panels and semiconductors, from magnesium die casting and other industrial applications; (5) Methane (CH{sub 4}) is emitted as a byproduct of some chemical processes; and (6) CH{sub 4} and N{sub 2}O can be emitted by food industry waste streams. Many GHG emission mitigation options have been developed for the industrial sector. They fall into three categories: operating procedures, sector-wide technologies and process-specific technologies. A sampling of these options is discussed in Sections 7.2-7.4. The short- and medium-term potential for and cost of all classes of options are discussed in Section 7.5, barriers to the application of these options are addressed in Section 7.6 and the implication of

    2003-12-01

    Full Text Available Given its simplicity and low cost compared to other types of methodologies, the measurement and interpretation of Electrochemical Noise, is consolidating itself as one of the analysis methods most frequently used for the interpretation of corrosion. As the technique is still evolving, standard treatment methodologies for data retrieved in experiments do not exist yet. To date, statistical analysis and the Fourier analysis are commonly used in order to establish the parameters that may characterize the recordings of potential and current electrochemical noise. This study introduces a new methodology based on wavelet analysis and presents its advantages with regards to the Fourier analysis in distinguishing periodical and non-periodical variations in the signal power in time and frequency, as opposed to the Fourier analysis that only considerers the frequency.

    Por su sencillez y bajo coste frente a otros tipos de metodologías, la medida e interpretación del Ruido Electroquímico, REQ, se está consolidando como uno de los métodos de análisis más utilizados para la interpretación del fenómeno de la corrosión. Al ser una técnica en desarrollo, no existen todavía metodologías estandarizadas de tratamiento de los datos obtenidos en los experimentos. Hasta la fecha, se suelen utilizar el análisis estadístico y el análisis de Fourier para establecer parámetros que puedan caracterizar a los registros de ruido electroquímico de potencial e intensidad. En este trabajo se introduce una nueva metodología basada en el análisis Wavelet que presenta las ventajas, respecto del análisis de Fourier, de poder distinguir variaciones periódicas y no periódicas de la potencia de la señal tanto en el dominio del tiempo, como en el de la frecuencia, y no sólo en el dominio de la frecuencia como ocurre en el caso del análisis de Fourier.

    Full Text Available The behaviour of the AA2024 alloy against corrosion in 3.5 % NaCl solution has been monitored. In this environment the alloy can be easily damaged under small anodic polarizations. Linear polarization, electrochemical impedance, spectroscopy and electrochemical noise meassurement have been used as experimental techniques. Data from ENM have been analized using statistical parameters and Chaos Theory. The results here obtained suggest that ENM is particularly useful to monitor systems that can be modified using other electochemical techniques.

    Full Text Available El objetivo del presente trabajo es detectar la no linealidad asociada al comportamiento de un transmisor de presión capacitivo tipo Rosemount, cuando éste sufre pérdidas de aceite. La metodología propuesta consiste en suponer un comportamiento dinámico bilineal. Se simula la respuesta tanto del transmisor como de su línea sensora a una excitación de tipo ruido blanco y se trata la señal de medida aplicando modelos autorregresivos univariantes. Se plantea la simulación introduciendo el empleo de dos familias de coeficientes autorregresivos para reproducir la bilinealidad, no considerando la ecuación estocástica asociada a la excitación por ruido blanco. A partir de los resultados se ha definido un índice de vigilancia paramétrica para complementar la medida del tiempo de respuesta del sensor, ya que dicho tiempo no es la magnitud adecuada para detectar la bilinealidad.The aim of this work is detecting the non linearity associated to a Rosemount capacitive transmitter when it suffers oil loss syndrome. The proposed methodology to characterize the non-linearity consists of assuming bilinear dynamic behaviour. The transmitter and sensing line response to a driven white noise is simulated and the signal is treated applying univariant autoregressive models. As a new approach, the simulation is achieved introducing the use of two autoregressive coefficients families to reproduce the bilinearity, omitting the stochastic equation associated to the driven white noise. Base on the analysis of the results, a parametric surveillance index is defined to complement the measurement of the response time, as this time is not the appropriate quantity to detect the bilinearity.

    1999-07-01

    A detailed and comprehensive research and development methodology is being prescribed to produce Oxide Dispersion Strengthened (ODS)-Fe3Al thin walled tubes, using powder extrusion methodologies, for eventual use at operating temperatures of up to 1100C in the power generation industry. A particular 'in service application' anomaly of Fe3Al-based alloys is that the environmental resistance is maintained up to 1200C, well beyond where such alloys retain sufficient mechanical strength. Grain boundary creep processes at such high temperatures are anticipated to be the dominant failure mechanism.

En la rama del metal es muy común la presencia de contaminantes físicos y químicos. En este artículo se analizan ambos junto con ciertos hábitos personales, con la finalidad de ver su influencia conjunta en la pérdida auditiva laboral. Material y métodos. Se analiza una muestra de 558 trabajadores mediante regresión de Cox con una finalidad explicativa. Se define el carácter de las relaciones causa-efecto existentes entre las variables consideradas, con respecto a tres situaciones: sano/alterado; recuperable/no recuperable; sin caídas en conversacionales/con caídas en conversacionales. Resultados. El análisis refleja que los fluidos de mecanizado, en presencia de ruido, retrasan la adquisición de los diversos grados de alteración auditiva; efecto contrario al que producen los humos metálicos, que adelantan la adquisición de dichos estadios. El hábito de fumar se reconoce como influyente en la adquisición de un trauma acústico inicial; la exposición a ruido extralaboral influye en la adquisición de un trauma acústico avanzado; y por otro lado, los equipos de protección auditiva son protectores del ruido pero no de la ototoxicidad de los humos metálicos. Conclusión. Se pone de manifiesto el efecto antagónico de los fluidos de mecanizado y el sinérgico de los humos metálicos frente al ruido, explicando la variación temporal en la evolución de la alteración auditiva, relacionada con estas atmósferas; se comprueba la influencia del tabaco y del ruido extralaboral, en la adquisición del trauma acústico.Background.

    Full Text Available A novel theoretical and experimental approach for lifetime modelling of MCrAlY coatings for stationary gas turbines has been undertaken using the Inverse Problem Solution (IPS technique. With this technique feasible experimental data acquired after a defined experimental time t e are used as input values for the model parameters estimation. In the first stage of the approach a model, based on the oxidation and diffusion processes (Fick's first and second law was assumed, which considers the Al concentration profile across the coating. The measured average Al concentration profiles in the two-phase g+b and g - regions of coating as well as base metal were used as input values for the model parameters estimation and calculational prediction of the long term diffusion and oxidation behavior of the coating was performed. The time, when the b-NiAl phase is completely consumed was assumed as the coating lifetime end. Exposure experiments were carried out with a NiCoCrAlY coating (200 micron thickness with 8% Al in air at 900 °C and 950 °C, currently up to 10000 h. The oxide scale is growing continuously and no other oxides were observed. The average and b-NiAl phase concentration profiles of Al across the coating thickness were determined by electron microprobe and image analysis systems in the initial state after 700 and 10000 h of oxidation. The concentration profile measured after 700 h was used as input values for the model parameters estimation in order to calculate the Al and b-NiAl phase concentration profiles after 10000 h. The computational forecast for 10000 h at 950 °C and 900 °C are in good agreement with the measured data. The approach was applied for NiCoCrAlY (200 micron thickness coating lifetime modelling at 950 °C and 900 °C as well as for different coating thicknesses at 950 °C.

    Chen, Nian

    For the long-term strategy of gradual decarbonization of the world's energy supply, high penetration of PV electricity is critical in the future world energy landscape. In order to achieve this, solar electricity with competitive cost to fossil fuel energy is necessary. To be able to obtain high efficiency solar cells, many advanced cell architectures have been developed commercially by PV industry. However, the fabrication of these cells necessitates complex processing steps and high requirements on semiconductor materials, which make it not as cost-effective as the state-of-the-art conventional Al-BSF structure. In order to keep the cost of PV cell low and improve on the efficiency with fewer processing steps, this thesis work focuses on the understanding of the conventional Al-BSF solar cell structure. The research work therefore, focuses on the (i) design, and modeling of front metal electrodes including the use of multi-bus-bar capable of decreasing the gridline resistance, (ii) fine-line printing and (iii) metal contact co-firing using high belt speed that is not common to the solar industry to achieve ~20% efficient industrial Al-BSF silicon solar cells. In order to achieve the objectives of this thesis work, firstly, the appropriate Al paste was investigated for lowest back surface recombination velocity (BSRV), which gives high open circuit voltage (Voc). Secondly, the impact of emitter sheet resistance on solar cell performance was modeled to determine the optimal sheet resistance, and the uniformity of emitter was also investigated. Thirdly, modeling on the front metal electrodes was carried out to investigate the optimal number of busbars, and determine the optimum number of gridlines and gridline geometries that would result in low series resistance (Rs), high fill factor (FF) and hence high efficiency. Fourthly, the modeled results were experimentally validated through fine-line printing and optimized contact co-firing. By combining each layer to make

    Full Text Available The launch of space craft generates extreme conditions, such as vibrations and acoustics that can affect the launch pad, space craft, and their payloads. The noise at launch and during the two-minute liftoff and transonic climb phase causes intense acoustic loads. These acoustic loads are the result of an intense acoustic environment generated by the interaction of the rocket-engine exhaust stream mixing with the atmosphere. Pyroshocks, that occur when spacecraft vehicle stages separate, cause additional vibration problems. In this article, an overview of the main aspects related to noise and vibration problems experienced by spacecraft structures is presented. Most of the information is based on the Space Shuttle experiences at the NASA's John F. Kennedy Space Center (KSC. In addition, a review of the vibroacoustic research being conducted at KSC is presented. These research programs are aimed at designing future space launch facilities, where cost and rocket exhaust launch noise are significantly reduced.El lanzamiento de los vehículos espaciales genera condiciones extremas, tales como de vibración y acústica, que pueden afectar la torre de lanzamiento, los vehículos espaciales y sus cargas. El ruido en el despegue y durante los dos minutos de ascenso y fase transónica causa intensas cargas acústicas. Estas cargas acústicas son el resultado del intenso medio ambiente acústico generado por la interacción del chorro de salida del motor del cohete y su mezcla con la atmósfera. Los choques pirotécnicos, que ocurren cuando las etapas de un vehículo espacial se separan, causan problemas adicionales de vibración. En este artículo se presenta una revisión de los principales aspectos relacionados con los problemas de ruido y vibración vividos por las estructuras de las naves espaciales.

    Full Text Available The major problem plaguing propane dehydrogenation process is the coke formation on the Pt-Sn/Al2O3 catalyst which leads to catalyst deactivation. Due to information paucity, the physicochemical characteristics of the commercially obtained regenerated Pt-Sn/Al2O3 catalyst (operated in moving bed reactor and coke formation at different temperatures of reaction were discussed. The physicochemical characterization of regenerated catalyst gave a BET surface area of 104.0 m2/g with graphitic carbon content of 8.0% indicative of incomplete carbon gasification during the industrial propylene production. Effect of temperatures on coke formation was identified by studying the product yield via temperature-programmed reaction carried out at 500oC, 600oC and 700oC. It was found that ethylene was precursor to carbon laydown while propylene tends to crack into methane. Post reaction, the spent catalyst possessed relatively lower surface area and pore radius whilst exhibited higher carbon content (31.80% at 700oC compared to the regenerated catalyst. Significantly, current studies also found that higher reaction temperatures favoured the coke formation. Consequently, the propylene yield has decreased with reaction temperature. © 2013 BCREC UNDIP.

    Unlike homogeneous catalysts, heterogeneous catalysts that have been optimized through decades are typically so complex and hard to characterize that the nature of the catalytically active site is not known. This is one of the main stumbling blocks in developing rational catalyst design strategies in heterogeneous catalysis. We show here how to identify the crucial atomic structure motif for the industrial Cu/ZnO/Al{sub 2}O{sub 3} methanol synthesis catalyst. Using a combination of experimental evidence from bulk-, surface-sensitive and imaging methods collected on real high-performance catalytic systems in combination with DFT calculations. We show that the active site consists of Cu steps peppered with Zn atoms, all stabilized by a series of well defined bulk defects and surface species that need jointly to be present for the system to work.

    The growing demand for high-quality transportation fuels requires their cost-effective production by hydrodesulfurization of crude oils using heterogeneous catalysts. To study the three-dimensional (3D) structure of such a commercial, sulfided Ni-Mo/gamma-Al2O3 catalyst, electron tomography was applied. The MoS2 particles form an interconnected complex structure within the mesopores of the alumina support. Spatial organization, morphology, and orientation of the MoS2 particles in the pores were resolved with sufficient accuracy to display the 6-A-spaced MoS2 crystal planes. The proximity of the MoS2 edge planes and more loosely interacting MoS2 basal planes to the alumina support showed the presence of pores smaller than 3 nm, which was confirmed by physisorption experiments. The actual shape of the MoS2 particles cannot be described by simple models as derived from studies on model catalysts. Electron tomography is a unique tool to study the actual 3D structure of complex industrial catalysts with sub-nanometer resolution.

    To verify noise emissions from the usual activities in an operating geothermal field, noise measurements were carried out in a 4.2 km{sup 2} area in the southern zone of the Los Azufres, Mich., geothermal field. There are seven production wells operating here and three abandoned wells. The average noise emission in the southern zone was 36.5 decibels (dB), regarded as the natural reading of environmental-noise emission. In the Christmas (valves) tree for operating production wells, the noise ranges from 70.9 to 91.7 dB, while in open discharging valves for steam-pipes, the noise can reach 118 dB. In Mexico the maximum permissible limit of noise on the periphery of a property is 68 dB in daytime and 65 dB at night. Based on measurements made at the periphery of lots where the geothermal wells are located, four out of seven production wells measured do not exceed the maximum allowable level, while the other three seem to exceed it. However no definite limits exist for the lots. It is recommended that the measurement points as indicated by the official standard in environmental matters be re-established, which will enable noise emissions by several wells that have exceeded the permissible limit, to actually fall within it.

En este artículo se plantea una metodología para determinar cómo un intervalo de cierta duración -en este caso, quince (15 minutos- para el muestreo del nivel de presión sonora es representativo para el período de una (1 hora, logrando de esta manera optimizar el uso de los sonómetros "fijos" y proponiendo una estrategia para reducir los costos en las mediciones de ruido ambiental y en general la elaboración de mapas de ruido.The managers of environmental noise measurements in environmental control agencies, or in general every person that work in this subject, have to think on the representativity of the unit measurement time interval, and how to evaluate it in order to get good quality results regarding the unit measurement time without increasing the measurement costs. A methodology for deciding if a certain measuring time interval -in this case, fifteen (15 minutes- is representative of noise pressure levels occurring during one hour, is proposed in this paper. This methodology allows to optimize the use of stationary sound level meters and to propose a strategy for reducing the costs of environmental noise measurements and of the designing of noise maps in general.

    Full Text Available The present study aims to synthesize SiAlON-based composites utilizing coal gangue. Different types of SiAlON-based composites were synthesized using coal gangue by carbothermal reduction nitridation method through control of different reaction atmospheres. The experimental results indicate that the oxygen partial pressure was an essential factor in the manufacture of SiAlON-based composites and under proper control of the atmospheres, SiAlON-based composites with different crystal structures could be synthesized. The optimum conditions of synthesis of different SiAlON-based composites were respectively determined. Based on the laboratory results, a prototype plant was proposed and constructed, and β-SiAlON composite was successfully produced using coal gangue. The synthesized β-SiAlON composite was applied in preparation of iron ladle brick instead of SiC, which showed that the compression strength, refractoriness under load and high temperature bending strength were increased from 44.5 ± 6.7 MPa, 1618 ± 21 °C and 5.4 ± 1.2 MPa to 64.1 ± 2.5 MPa, 1700 ± 28 °C and 7.1 ± 1.6 MPa, respectively. Compared with the traditional synthesis method, the present technique is expected to save energy both in raw materials and technical process.

    Volatile organic compounds' (VOCs) effluents, which come from many industries, are triggering serious environmental problems. As an emerging technology, non-thermal plasma (NTP) technology is a potential technology for VOCs emission control. NTP coupled with F-TiO2/γ-Al2O3 is used for toluene removal from a gaseous influent at normal temperature and atmospheric pressure. NTP is generated by dielectric barrier discharge, and F-TiO2/γ-Al2O3 can be prepared by sol-gel method in the laboratory. In the experiment, the different packed materials were packed into the plasma reactor, including γ-Al2O3, TiO2/γ-Al2O3 and F-TiO2/γ-Al2O3. Through a series of characterization methods such as X-ray diffraction, scanning electronic microscopy and Brunner-Emmet-Teller measurements, the results show that the particle size distribution of F-TiO2 is relatively smaller than that of TiO2, and the pore distribution of F-TiO2 is more uniformly distributed than that of TiO2. The relationships among toluene removal efficiency, reactor input energy density, and the equivalent capacitances of air gap and dielectric barrier layer were investigated. The results show that the synergistic technology NTP with F-TiO2/γ-Al2O3 resulted in greater enhancement of toluene removal efficiency and energy efficiency. Especially, when packing with F-TiO2/γ-Al2O3 in NTP reactor, toluene removal efficiency reaches 99% and higher. Based on the data analysis of Fourier Transform Infrared Spectroscopy, the experimental results showed that NTP reactor packed with F-TiO2/γ-Al2O3 resulted in a better inhibition for by-products formation effectively in the gas exhaust.

    The applicability of a light backscatter sensor with a large field of view was tested for on-line monitoring of coagulation and syneresis in a goat cheese (Murcia al Vino) manufactured under industrial conditions. Cheesemaking was carried out concurrently in a 12-L pilot vat and a 10,000-L industrial vat following the normal cheesemaking protocol. Cheese moisture, whey fat content, hardness, springiness, and adhesiveness were measured during syneresis. The results obtained show that cutting time is best predicted by considering the coagulation ratio at the inflection point and the percentage increase in the ratio during coagulation, with no need for the first derivative. The large field of view reflectance ratio provided good results for the prediction of moisture content, yield, hardness, springiness, and adhesiveness of the final cheese.

    Full Text Available The thermal spraying process is a surface treatment which does not adversely affect the base metal on which it is performed. The coatings obtained by HVOF thermal spray are employed in aeronautics, aerospace, and power generation industries. Alloys and coatings designed to resist oxidizing environments at high temperatures should be able to develop a surface oxide layer, which is thermodynamically stable, slowly growing, and adherent. MCrAlY type (M = Co, Ni or combination of both coatings are used in wear and corrosion applications but also provide protection against high temperature oxidation and corrosion attack in molten salts. In this investigation, CoNiCrAlY coatings were produced employing a HVOF DJH 2700 gun. The work presented here focuses on the influences of process parameters of a gas-drive HVOF system on the microstructure, adherence, wear, and oxygen content of CoNiCrAlY. The results showed that spray distance significantly affects the properties of CoNiCrAlY coatings.

    The utilisation of CO{sub 2} as feedstock in the chemical industry represents an alternative to the geological storage, which is legally limited and socially debated. Generally, scientific publications about the utilisation of CO{sub 2} in chemical reactions typically address the feasibility of the syntheses without paying attention to the CO{sub 2} reduction potential or the economy in contrast to the conventional process of production. The aim of this doctoral thesis is to identify chemical reactions with CO{sub 2} as feedstock, which have the potential to reduce CO{sub 2} emissions. These reactions are evaluated concerning the industrial realization, CO{sub 2} balance and economy compared to the conventional processes. To achieve this, 123 reactions from the literature were collected and evaluated with the help of selection criteria developed specifically for this application. The criteria consider both, the quantitative potential to reduce CO{sub 2} and possible economical interests in these reactions. Additional to the process of the evaluation of the reactions, a CO{sub 2} reduction potential of 1.33 % of the greenhouse gas emissions within the European Union could be calculated. For the chemicals formic acid, oxalic acid, formaldehyde, methanol, urea and dimethyl ether, which most fully satisfy the selection criteria, a direct comparison of the CO{sub 2} based process with the conventional process is performed. By literature data, process designs, and simulations, it has been shown that the highest reductions of CO{sub 2} emissions can be achieved for methanol with 1.43 kg{sub CO2}/kg{sub MeOH} and dimethyl ether with 2.17 kg{sub CO2}/kg{sub DME}, but only with the assumption that the necessary hydrogen for the CO{sub 2} based reaction is produced by electrolysis operated with renewable energy. Overall, the CO{sub 2} based production processes of methanol and dimethyl ether could reduce 0.059 % of the greenhouse gas emissions of the European Union (EU) if

Los niveles de presión sonora se cuantificaron según Asociación Brasileña de Normas Técnicas, con uso de medidor de nivel de presión sonora. Los promedios se clasificaron según los niveles de conforto, incomodidad y daño auditivo propuestos por la Organización Panamericana de Salud. A las educadoras se les evaluó la voz: auto-evaluación con escala analógica visual, evaluación perceptivo-auditiva con escala GRBAS y análisis acústico con el programa Praat. Para análisis de asociación entre ruido y evaluación vocal, se utilizó estadística descriptiva y prueba de chi-cuadrado, con 10% de significancia debido al tamaño de la muestra. RESULTADOS: Las educadoras presentaban edades entre 21 y 56 años. El promedio de ruido fue 72,7dB, considerado daño 2. La auto-evaluación vocal de las profesionales presentó promedio de 5,1 en la escala, considerada alteración moderada. En la evaluación perceptivo-auditiva, 74% presentaron alteración vocal, principalmente ronquera; de estas, 52% fueron consideradas alteraciones leves. La mayor parte presentó frecuencia fundamental por debajo de lo esperado en la evaluación acústica. Promedios de jitter, shimmer y proporción armónico-ruido estaban alterados. Presencia de ruido entre los armónicos se asoció a alteración vocal. CONCLUSIONES: Hubo asociación entre presencia de ruido entre armónicos y alteración vocal, con elevados niveles de ruido. A pesar de que la mayoría de las educadoras presentaron voz alterada en grado reducido, la auto-evaluación mostró alteración moderada, probablemente por la dificultad de proyección.OBJECTIVE: To analyze the association between noise levels present in preschool institutions and vocal disorders among educators.

    Full Text Available Present design trends in automotive manufacture have shifted emphasis to alternative lightweight materials in order to achieve higher fuel efficiency and to bring down vehicle emission. Although some other joining techniques are more and more being used, spot welding still remains the primary joining method in automobile manufacturing so far. Spot welds for automotive applications should have a sufficiently large diameter, so that nugget pullout mode is the dominant failure mode. Interfacial mode is unacceptable due to its low load carrying and energy absorption capability. Strength tests with different static loading were performed in, to reveal the failure mechanisms for the lap-shear geometry and the cross-tension geometry. Based on the literature survey performed, venture into this work was amply motivated by the fact that a little research work has been conducted to joining of dissimilar materials like non ferrous to ferrous. Most of the research works concentrated on joining of different materials like steel to steel or aluminium alloy to aluminium alloy by resistance spot welding. In this work, an experimental study on the resistance spot weldability of aluminium alloy (Al 6063 and austenitic stainless steel (AISI304 sheets, which are lap joined by using a pedestal type resistance spot welding machine. Welding was conducted using a 45-deg truncated cone copper electrode with 10-mm face diameter. The weld nugget diameter, force estimation under lap shear test and T – peel test were investigated using digital type tensometer attached with capacitive displacement transducer (Mikrotech, Bangalore, Model: METM2000ER1. The results shows that joining of Al 6063 and AISI 304 thin sheets by RSW method are feasible for automotive structural joints where the loads are below 1000N act on them, it is observed that by increasing the spots per unit length, then the joint with standing strength to oppose failure is also increased linearly incase of

    Full Text Available Los valores sociales son un elemento esencial para el análisis histórico de la actividad física y el deporte. El cambio del sistema de valores que significó el paso de la sociedad estamental a la sociedad de clases facilitó la práctica física y deportiva en el marco de un nuevo significado del cuerpo y de la disciplina social. La sociedad tradicional tenía su referente principal en la religión y en sus principios seculares del movimiento del cuerpo como hecho sujeto a discusión moral. Con la nueva sociedad surgida con la Revolución Industrial se abre una nueva concepción del cuerpo como objeto educativo para su orientación laboral. Aparece primero la gimnasia como una herramienta para la instrucción colectiva en la nueva disciplina del movimiento reglado del cuerpo. Después, se imponen los deportes ingleses que se basan en la estrategia de equipo y en el juego según reglas. En ambos casos, gimnasia y deporte responden a un nuevo núcleo de valores en los que la competencia, la unión y la superación son los referentes dominantes. A su vez, tales valores están ligados al espíritu nacionalista emergente en el siglo XIX. Así, el nacimiento de los Estados–Nación en Europa va en paralelo con la economía industrial y con una nueva concepción corporal que evoluciona desde la gimnasia hasta el deporte. En este artículo se analiza el caso de la modernización de España, indicando ejemplos ilustrativos del cambio en los valores de la actividad física practicada en el tránsito del siglo XIX al XX.--------------------------------------------------------------------------Social values are an essential feature for the historic analysis of physical activity and sport.

    Full Text Available Given that the experimental signals obtained in an electrochemical noise measurement, ENM, are recorded over a discrete time period, the most direct way of analising them will be in the time domain resorting to statistical methods. These can be classified into two groups according to use: those which attempt to quantify the degree of the corrosion process (standard deviations, statistical power; and those which attempt to provide information on the corrosion mechanism (based on the assumption that the shape of the time records is a reflection of itself. Among the later the use of the average, the skewness and the kurtosis of the signals or the pitting index can be pointed out as being able to reflect the changes in the corrosion mechanism. Noise resistance stands out above all these parameters. In this work has undertaken the statistical treatment of ENM data obtained by subjecting aluminium to three electrolytes that provoke several types of corrosion in it: passivity, pitting corrosion and generalized corrosion.

    En la mayoría de los experimentos sobre ruido electroquímico, ENM (Electrochemical Noise Measurement, las señales experimentales se registran durante períodos de tiempo discretos. Resulta habitual, por ello, que en las publicaciones sobre esta técnica, la forma más directa de analizar esos datos consiste en acudir a métodos estadísticos en el dominio temporal. Estos métodos pueden ser clasificados, según su utilidad, en dos grupos: aquellos que pretenden cuantificar la magnitud del proceso de corrosión (desviaciones estándar, potencia estadística, etc. y los que tratan de extraer información sobre el mecanismo del proceso corrosivo en sí mismo, los cuales se basan, en su mayoría, en la suposición de que la forma de los registros temporales son un reflejo del comportamiento de la interfase metal electrólito. Entre estos últimos, se pueden destacar el valor medio, el sesgo, la curtosis y el índice de picaduras

    Full Text Available Un aspecto ambiental se considera como cualquier material o elemento físico o químico que el hombre arroja al agua, al aire y al suelo o que interactúe con el ambiente y propicie un riesgo para la salud y para el medio ambiente. Los residuos originados durante el desarrollo de actividades relacionadas con la experimentación química, aunque en una proporción menor que en un proceso industrial, ellos pueden ser residuos peligrosos al medio ambiente. Los aspectos ambientales se asocian con las actividades de generación de residuos, derrames, emisión a la atmósfera, el consumo de recursos naturales y ruido. Este estudio tuvo como objetivo proponer directrices para identificar y clasificar a los residuos que son generados en una experimentación química e introducir aspectos de seguridad para la salud y para el medio ambiente dentro de los procedimientos analíticos. Se inició con una evaluación diagnóstica sobre el conocimiento de la normativa en materia de gestión de los residuos o desechos, dirigida a técnicos y profesores que realizan actividades en ocho laboratorios para la enseñanza de la Química. Se siguió con la selección de un procedimiento analítico, como caso estudio, para revisar y aplicar estrategias de reusar, reciclar y reducir la generación de los residuos. Se encontró un desconocimiento de la normativa ambiental, representada por el 73% de los encuestados y un escaso tratamiento de residuos. Se concluye que la extensión de aspectos ambientales en los procedimientos analíticos puede ayudar a prevenir la contaminación ambiental, a fortalecer aspectos toxicológicos, de seguridad y de prevención de riesgos laborales.

    Ziegler-type hydrogenation catalysts are important for industrial processes, namely, the large-scale selective hydrogenation of styrenic block copolymers. Ziegler-type hydrogenation catalysts are composed of a group 8-10 transition metal precatalyst plus an alkylaluminum cocatalyst (and they are not the same as Ziegler-Natta polymerization catalysts). However, for ∼50 years two unsettled issues central to Ziegler-type hydrogenation catalysis are the nature of the metal species present after catalyst synthesis, and whether the species primarily responsible for catalytic hydrogenation activity are homogeneous (e.g., monometallic complexes) or heterogeneous (e.g., Ziegler nanoclusters defined as metal nanoclusters made from combination of Ziegler-type hydrogenation catalyst precursors). A critical review of the existing literature (Alley et al. J. Mol. Catal. A: Chem. 2010, 315, 1-27) and a recently published study using an Ir model system (Alley et al. Inorg. Chem. 2010, 49, 8131-8147) help to guide the present investigation of Ziegler-type hydrogenation catalysts made from the industrially favored precursors Co(neodecanoate)(2) or Ni(2-ethylhexanoate)(2), plus AlEt(3). The approach and methods used herein parallel those used in the study of the Ir model system. Specifically, a combination of Z-contrast scanning transmission electron microscopy (STEM), matrix assisted laser desorption ionization mass spectrometry (MALDI MS), and X-ray absorption fine structure (XAFS) spectroscopy are used to characterize the transition metal species both before and after hydrogenation. Kinetic studies including Hg(0) poisoning experiments are utilized to test which species are the most active catalysts. The main findings are that, both before and after catalytic cyclohexene hydrogenation, the species present comprise a broad distribution of metal cluster sizes from subnanometer to nanometer scale particles, with estimated mean cluster diameters of about 1 nm for both Co and Ni.

    A discussion over the feasibility of implementing an unbalanced economic growth strategy is presented. With the proposed sectorial classification, it is demonstrated that the Mexican economy has an important heterogeneous and segmented growth pattern. The input-output matrix and the developed exercises, for the year 2003, reflect that hydrocarbons and the export maquiladora industry do not generate meaningful productive linkages. With the passive optimistic economic growth scenario, towards the end of 2015, between 3.8 and 5.6 million additional people with a self-employed, unemployed or emigrant status will be generated. A set of sectorial and aggregated policies with a post-keynesian-structural nature are proposed in order to improve the productive linkages and the labor market. [Spanish] Se presenta una discusion sobre la viabilidad de implantar una estrategia de crecimiento economico desbalanceado. Se demuestra que con la clasificacion sectorial propuesta, la economia mexicana tiene un patron de crecimiento marcadamente heterogeneo y segmentado. La matriz insumo-producto y los ejercicios desarrollados para el 2003 reflejan que los hidrocarburos y la industria maquiladora de exportacion no generan encadenamientos productivos significativos. En el escenario pasivo optimista de crecimiento economico, hacia finales de 2015, se generarian entre 3.8 y 5.6 millones de personas adicionales de autoempleados, desempleados o emigrantes. Se proponen un conjunto de politicas sectoriales y agregadas de naturaleza postkeynesiana-estructuralista para mejorar los encadenamientos productivos y la situacion del mercado laboral.

    Full Text Available Si bien muchos economistas son conscientes del efecto de los días hábiles sobre la medición de la producción, aún es frecuente encontrar que estas cifras se analizan sin el correspondiente ajuste. En general, el número de días hábiles en un mes cambia de un año a otro, lo cual es cierto para todos los meses, no solo para los que contienen la Semana Santa. Este trabajo recopila la serie de días hábiles mensuales tomando en cuenta los festivos actuales y anteriores a la Ley Emiliani, y la utiliza para ajustar la serie de producción manufacturera del DANE. Para algunos meses, la diferencia entre la cifra de crecimiento industrial reportada por el DANE y la cifra ajustada por días hábiles puede acercarse a los 12 puntos porcentuales, en cualquier dirección

    On a company ground in Vorchdorf, Austria, from the 23{sup rd} to 26{sup th} of July 1996 an air-sparging experiment has been carried out as a supporting measure to a running redevelopment of an LCKW-contamination case. On this occasion compressed air, from which the oil had been extracted, was blown into the contaminated aquifer through a well with a maximum excess pressure of 0,6 MPa. The blowing-in of compressed air caused a mobilisation of the harmful substances in the ground water and the soil air. As a result circa 2,7 kg LCKW could be removed from the underground through neighbouring ground water and soil air wells. For the observed period of time this meant a tripling of the rate of discharge. On the basis of the obtained data we suggested a routine interval of blowing in compressed air into the well 1516. A blowing-in of compressed air into the highly contaminated wells 1617 and 1625 can not be realised until the construction of upstream situated injection wells, because of the danger of an uncontrollable spread of the harmful substances.

Hierbei wurde entoelte Druckluft ueber einen Brunnen mit einem maximalen Ueberdruck von 600 mbar in den kontaminierten Aquifer eingeblasen. Die Drucklufteinblasung fuehrte zu einer Mobilisierung von Schadstoffen im Grundwasser und in der Bodenluft, so dass ueber benachbarte Grundwasser- und Bodenluftfoerderbrunnen ca. 2,7 kg LCKW aus dem Untergrund entfernt werden konnten. Fuer den Beobachtungszeitraum bedeutet dies eine Verdreifachung des Schadstoffaustrags.

    other molecules. This particular hydrophilicity is due to the presence of active adsorption centers on the surface of sepiolite. Taking into account this mineral is used as absorbent and as reinforcement in plastics, the highest length/diameter ratio is needed in order to maximize properties. Then, fiber disaggregation would increase its application field and the added value of this untapped mineral in Argentina. In this work, different methods as liofilization, sonication and acid leaching are explored, focusing in the optimization of disaggregation and purification of the fibers. The comparative analysis was made through the sepiolite characterization before and after each treatment by electronic and optical microscopy, x ray diffraction, infrared spectroscopy and thermal analysis. The results obtained from the acid leaching describe it as the better treatment respect to the sepiolite purification due to carbonates elimination. The sonication allows a particular disaggregation, leading to a gel structure development, product of the high entanglement of nanofibers which retain water molecules inside the network. In the case of the liofilization, it produces a substantial morphological variation of the fibers respect to their disaggregation. This method is the best for conserving the initial length of the fibers. These results allow inferring that the sepiolite can be easily processed and be used in different industries in our country with a high added value, replacing its importation.

    Different authors have published lists of chemicals, especially pesticides and industrial chemicals, reported to have 'reproductive and endocrine disrupting activities' or 'estrogenic/antiestrogenic' activities. The objective of this study was to examine what is the basis for and whether it is justified to classify chemical compounds as 'endocrine disrupters' that are contained in frequently cited overviews, but have not been discussed in a previous report (UBA-TEXTE 46/97). Depending on the level of evidence derived from literature data, substances are classified either as (i) endocrinally active or (ii) potentially endocrinally active or (iii) without sufficient data on endocrine activity. The criteria used for the classification are based on the definitions by US-EPA and the Weybridge conference. (orig.) [German] Von verschiedenen Autoren sind umfangreiche Listen mit Chemikalien, insbesondere Pestiziden und Industriechemikalien, veroeffentlicht worden, die als 'endokrin wirksam und reproduktionstoxisch' oder als 'oestrogen- bzw. 'antioestrogen wirksam' bezeichnet werden. Aufgabe der vorliegenden Studie ist es, zu untersuchen, auf welchen Grundlagen die Einstufung als 'endokrin wirksam' beruht, und zu ueberpruefen, ob sie gerechtfertigt ist. Je nach den Ergebnissen der Literaturrecherchen werden die Substanzen einer von drei Gruppen zugeordnet: 1. endokrin wirksam, 2. potentiell endokrin wirksam, 3. ohne ausreichende Hinweise auf endokrine Wirksamkeit. Die verwendeten Kritetien fuer die Zuordnung lehnen sich an die Definitionen der EPA und der Weybridge-Konferenz an.

The main variables of treatment have been established on the basis of a thermodynamic model that includes parameters as sulphur capacity of the slag, optical basicity of oxides and of the slags, the activities of oxides in the slags and activities of elements in the liquid steel. Sulphur contents at the end of treatment, are close to the values predicted by the model. Low sulfur levels achieved in the process, facilitate the subsequent treatment with calcium to modify the inclusions. Finally an evaluation is presented concerning the effects resulting from the reoxidation of the melt on the main indicators, showing the efficiency of the applied treatment for desulphurization.En este trabajo se presentan los resultados de algunos ensayos de desulfuración en cuchara, llevados a cabo a escala industrial, para aceros con bajo contenido en carbono, de baja aleación y calmados con aluminio, utilizando escorias basicás y corriente de argón.

Energy consumption is decreased by injecting gaseous oxygen, however, slag oxidation also increases. In order to reduce the extent of oxidation while keeping a high volume of the oxygen injected, it is required: a to optimize the carbon injection practice, b to increase the carbon concentration of sponge iron, c to operate with soluble carbon in both the metal and the slag beyond a critical level and d to employ a low temperature profile, on average 1,650°C. A method to define the proper amount of carbon in sponge iron which considers their metallization as well as the amount of oxygen injected is proposed. The position of the lance is critical in order to optimize the practice of carbon injection and assure a better residence time of the carbon particles within the furnace.

  4. Industrial Chain: Industrial Vertical Definition

    Like value chain and supply chain, “industrial chain” becomes the focus of attention. The implication of “industrial chain” has gained a large range of extension. It not only expresses the industrial “chain” structure and relationship of “back and forward”in order or “up and down” in direction, but also it represents a cluster of large scale of firms in an area or colony. It is a network, or a community. Consequently, we conclude that “industrial chain” is a synthesis of industrial chain, industrial cluster, or industrial network.In this article, firstly we will distinguish industry chain from industry. An industry is the collection of firms that have the same attribute, so an industry can be defined by firm collection of certain attribute. We indicate that industrial chain is a kind of vertical and orderly industrial link. It is defined according to a series of specific product or service created. Secondly we analyze the vertical orderly defiinition process from the aspects of social division of labor and requirement division, self-organization system, and value analysis.Non-symmetry and depending on system or community of large scale of industrial units lead to entire industry to “orderly” structure. On the other hand, the draught of diversity and complexity of requirement simultaneously lead to entire industry to be more “orderly”. Along with processes of self-organization, industrial will appi'oach the state of more orderly and steady, and constantly make industrial chain upgrade. Each firm or unit, who will gain the value, has to establish channels of value, which we called “industrial value chain”. Lastly,we discuss the consequence of vertical and orderly definition, which is exhibited by a certain relationship body. The typical forms of industrial chain include industrial cluster, strategy alliance and vertical integration etc.

    Full Text Available Objetivo: A partir de la determinación de las dosis en los protocolos habitualmente utilizados en estudios de tomografía computada en una institución, se modificaron la menor cantidad de parámetros radiológicos posibles para bajar las dosis impartidas, sin perder la calidad de la imagen. Materiales y métodos: Para la determinación de las dosis en un tomógrafo General Electric Hi Speed - 120kV Helicoidal, se realizaron mediciones utilizando una cámara de ionización tipo lápiz, un dosímetro, fantomas craneal y abdominal de PMMAde 16 cm y 32 cm de diámetro respectivamente, y un fantoma de agua. Con estos elementos se midieron las dosis habitualmente utilizadas y el ruido correspondiente en cada uno de los estudios. Se trabajó con el grupo de técnicos ymédicos de la institución con el objetivo de disminuir la dosis de cada uno de los protocolos utilizados, manteniendo imágenes con calidad diagnóstica. Resultados: Si bien las dosis de los protocolos utilizados por la institución antes de realizado este estudio se encontraban dentro de los rangos reconocidos internacionalmente, se establecieron nuevos protocolos y se pudieron reducir las dosis entre un 20% a un 30%, sin perder calidad ni presentar inconvenientes para el diagnóstico al grupo médico que trabaja en la institución. Conclusiones: Es fundamental realizar actividades de optimización de protocolos en tomografía computada con el objetivo de disminuir la dosis que reciben los pacientes, modificando apropiadamente los parámetros de los protocolos sin perder calidad diagnóstica ni afectar la actividad médica. Esta tarea debe llevarse a cabo en forma interdisciplinaria.Purpose: To determine the dose frequently used in computed tomography and to modify radiological parameters in order to optimize each protocol according to the dose administered.

    Full Text Available In this article the possibility of using waste from the petrochemical industry,as partial replacement of Portland cement is studied, evaluating the presenceof contaminants in the waste and the encapsulation, once it is confined on the cement. This has been done, in order to find a use to this residue without cause damage to the environment. This residue, called spent fluid catalytic cracking catalyst (FCC, is mainly formed by a type Y zeolite, which is dispersing in an inorganic oxides matrix. The toxicity characteristic leaching proceeding was applied, in mortars adding with 20% of FCC as Portland cement replacement. The results showed that the residue does not represent a problem from the point of view of the leaching of elements, such as As, Pb, Zn, Cr, and La, which were below to the permissible limits. Additionally, the pozzolanic activity of FCC was evaluated according to ASTM C311, where the efficiency of the residue as pozzolanic addition is demonstrated. With the results the importance of reusing a residue of the petrochemical industry is emphasized, that decreases the amount of cement to be used and improves the mechanical resistance of the materials containing it.En el presente artículo se estudia la posibilidad de utilizar un residuo de la industria petroquímica, como sustitución parcial del cemento Portland, evaluando la presencia de elementos contaminantes en el residuo y su encapsulación, una vez se haya confinado con el cemento.

    Full Text Available In this work a study on the application of bio-inspired strategies for optimization to Fault Diagnosis in industrial systems is presented. The principal aim is to establish a basis for the development of new and viable model-based Fault Diagnosis Methods which improve some difficulties that the current methods cannot avoid. These difficulties are related mainly with fault sensitivity and robustness to external disturbances. In this study, there have been considered the Differential Evolution and the Ant Colony Optimization algorithms. This application is illustrated using simulated data of the Two tanks system benchmark. In order to analyze the advantages of these algorithms to obtain a diagnosis which needs to be sensitive to faults and robust to external disturbances, some experiments with incipient faults and noisy data have been simulated. The results indicate that the proposed approach, basically the combination of the two algorithms, characterizes a promising methodology for Fault Diagnosis.En el presente trabajo se presenta un estudio sobre la aplicación de estrategias bioinspiradas para la optimización al diagnóstico de fallos en sistemas industriales. El objetivo principal es establecer una base para el desarrollo de nuevos y viables métodos de diagnóstico de fallos basados en modelos que permitan mejorar las dificultades de los métodos actuales. Estas dificultades están relacionadas, fundamentalmente, con la sensibilidad ante la presencia de fallos y la robustez ante perturbaciones externas. En el estudio se consideraron los algoritmos Evolución Diferencial y Optimización por Colonia de Hormigas. La efectividad de la propuesta es analizada mediante experimentos con el conocido problema de prueba de los dos tanques. Los experimentos consideraron presencia de ruido en la información y fallos incipientes de manera que fuera posible analizar las ventajas de la propuesta en cuanto a diagnóstico robusto y sensible.

Los extrabajadores fueron sometidos a anamnesis clínico-ocupacional, radiografía de tórax y espirometría. Fue creado un escore de exposición que multiplicado por la duración, originó un índice de exposición acumulativa al talco. Para testar la asociación del índice de exposición acumulativa con la presencia de alteraciones radiológicas, sugestivas de neumoconiosis e/o alteraciones pleurales, fue ajustado un modelo de regresión logística exacta. RESULTADOS: Todos los extrabajadores eran hombres, con promedio de edad de 48,2 años. En las radiografías de tórax fueron encontradas alteraciones pleurales en tres de ellos, opacidades parenquimatosas compatibles con neumoconiosis en uno y sospecha en seis. Alteraciones espirométricas ocurrieron en tres. La regresión logística indicó odds ratio de 1,059 (IC 95%:1,012;1,125 para el índice acumulado, es decir, cada unidad en el índice resulta en un aumento de 5,9% en el chance de presentar alteración radiológica compatible o con sospecha de neumoconiosis.

    Full Text Available Abstract Definition of the disease AL amyloidosis results from extra-cellular deposition of fibril-forming monoclonal immunoglobulin (Ig light chains (LC (most commonly of lambda isotype usually secreted by a small plasma cell clone. Most patients have evidence of isolated monoclonal gammopathy or smoldering myeloma, and the occurrence of AL amyloidosis in patients with symptomatic multiple myeloma or other B-cell lymphoproliferative disorders is unusual. The key event in the development of AL amyloidosis is the change in the secondary or tertiary structure of an abnormal monoclonal LC, which results in instable conformation. This conformational change is responsible for abnormal folding of the LC, rich in β leaves, which assemble into monomers that stack together to form amyloid fibrils. Epidemiology AL amyloidosis is the most common type of systemic amyloidois in developed countries with an estimated incidence of 9 cases/million inhabitant/year. The average age of diagnosed patients is 65 years and less than 10% of patients are under 50. Clinical description The clinical presentation is protean, because of the wide number of tissues or organs that may be affected. The most common presenting symptoms are asthenia and dyspnoea, which are poorly specific and may account for delayed diagnosis. Renal manifestations are the most frequent, affecting two thirds of patients at presentation. They are characterized by heavy proteinuria, with nephrotic syndrome and impaired renal function in half of the patients. Heart involvement, which is present at diagnosis in more than 50% of patients, leading to restrictive cardiopathy, is the most serious complication and engages prognosis. Diagnostic methods The diagnosis relies on pathological examination of an involved site showing Congo red-positive amyloid deposits, with typical apple-green birefringence under polarized light, that stain positive with an anti-LC antibody by immunohistochemistry and

    Estimated 2012 world production of natural and synthetic industrial diamond was about 4.45 billion carats. During 2012, natural industrial diamonds were produced in at least 20 countries, and synthetic industrial diamond was produced in at least 12 countries. About 99 percent of the combined natural and synthetic global output was produced in Belarus, China, Ireland, Japan, Russia, South Africa and the United States. During 2012, China was the world’s leading producer of synthetic industrial diamond followed by the United States and Russia. In 2012, the two U.S. synthetic producers, one in Pennsylvania and the other in Ohio, had an estimated output of 103 million carats, valued at about $70.6 million. This was an estimated 43.7 million carats of synthetic diamond bort, grit, and dust and powder with a value of $14.5 million combined with an estimated 59.7 million carats of synthetic diamond stone with a value of $56.1 million. Also in 2012, nine U.S. firms manufactured polycrystalline diamond (PCD) from synthetic diamond grit and powder. The United States government does not collect or maintain data for either domestic PCD producers or domestic chemical vapor deposition (CVD) diamond producers for quantity or value of annual production. Current trade and consumption quantity data are not available for PCD or for CVD diamond. For these reasons, PCD and CVD diamond are not included in the industrial diamond quantitative data reported here.

    Mg{sub 2}Si thermoelectric device was fabricated using Si sludge and recycled Mg alloys of the Mg-Al-Zn-Mn system. Its thermoelectric properties, such as the Seebeck coefficient, electrical conductivity and thermal conductivity, were measured, and then a dimensionless figure-of-merit, ZT, was estimated over the temperature range from 300 to 860 K. The actual output power measurements were made using specimens that were equipped with monobloc-sintered Ni electrodes under a temperature gradient {delta}T ranging from 100 to 500 K. The ZT values for the samples fabricated from reused-Si and recycled Mg-alloys were about 0.6 at 860 K, presenting no notable difference compared with specimens fabricated from pure Si and Mg sources. The observed maximum output power for a sample size of 2x2x10 mm{sup 3} was 35 mW at {delta}T = 500 K, where the sample was initiated from a reused Si source with 2 at% of Al doping. (orig.)

    Currently, the existing information systems, and specifically the ERP, can not give adequate support to the management of manufacturing companies of ceramic tile, because, among other reasons, not to contemplate the existence of tone, size and quality within the same product. This feature, caused by the lack of homogeneity of the product (LHP), generates various problems in managing the product through the different business processes, such as, stocks management, order management, the production management, etc. Thus, it is necessary to develop an ERP solution that is able to manage adequately the ceramic product, including tone, size and quality.

    Currently, the existing information systems, and specifically the ERP, can not give adequate support to the management of manufacturing companies of ceramic tile, because, among other reasons, not to contemplate the existence of tone, size and quality within the same product. This feature, caused by the lack of homogeneity of the product (LHP), generates various problems in managing the product through the different business processes, such as, stocks management, order management, the production management, etc. Thus, it is necessary to develop an ERP solution that is able to manage adequately the ceramic product, including tone, size and quality. In this paper we analyze the requirements of the ceramic sector, in terms of product identification, and propose a data model to meet these requirements. The model arises as a basic guide for the development of vertical ERP solutions tailored to the ceramic industry. (Author)

MATERIAL Y MÉTODOS. Se realizó un estudio de cohorte a 725 mujeres empleadas en una planta japonesa y una estadunidense, entre enero de 1992 y marzo de 1994. La muestra se estratificó en dos intervalos de tiempo ­30 y >30 días laborados. Se efectuó un seguimiento de las mujeres hasta su renuncia o final del periodo de observación, mediante la recolección de información sobre variables de salud, sociales y ocupacionales de diversas fuentes de registro obtenidas de su centro de trabajo. Los motivos de renuncia y la confiabilidad de los datos obtenidos de los registros se estudiaron por medio de entrevistas de seguimiento realizadas a 46% (n= 148 de las trabajadoras que renunciaron y fueron localizadas aproximadamente 12 meses (desviación estándar= 6.7 después de su renuncia. RESULTADOS. La probabilidad acumulativa de renunciar al trabajo fue de 67% en el primer año y de 81% en el segundo. La ausencia de antecedentes laborales previos, turno diurno y nacionalidad de la compañía, resultaron factores predictivos para la renuncia al empleo durante los primeros 30 días. Tabaquismo, antecedentes quirúrgicos y haberse incapacitado por enfermedad general, después de controlar por otras variables, actuaron como factores predictivos para la renuncia posterior a 30 días. En contraposición, la tasa de renuncia posterior a 30 días resultó menor para mujeres con enfermedades crónicas. CONCLUSIONES. La renuncia al empleo en las maquiladoras es elevada y selectiva; en tanto que los factores ocupacionales se asociaron con la renuncia temprana, los relacionados con la salud fueron mejores factores predictivos para la renuncia posterior a los primeros 30 días.OBJECTIVE.

    Perovskite-type ceramic oxides or their derivatives are used for applications in high technology because of their enormous range of physic-chemical properties with little change in structural characteristics. In this paper we report manufacture ceramic components of a new ceramic Ca{sub 2}AlWO{sub 5,5} by thermo-mechanical process. Stoichiometric amounts of chemical constituents with high degree of purity, were homogenized using a ball mill and high purity alumina balls, compacted by uniaxial pressing and annealed at 1200 deg C for 48 hours. The structural characterization studied by x-ray diffraction that this material has a typical complex ordered cubic perovskite structure. For the study the stability of these ceramics in crude petroleum circular discs of 20 mm diameter and 2 mm thickness were produced and sintering. These discs were submerged in crude petroleum for 15, 30 and 45 days and were examined at each stage by X-ray diffraction, optical microscopy and hardness testing and these results show that Ca{sub 2}AlWO{sub 5,5} are stable in crude petroleum environment.

Con la finalidad de valorar de forma objetiva el efecto real que la recuperación de una vieja industria tiene sobre la revitalización de un entorno, y tomando como base la antigua fábrica de electricidad de Mediodía, se lleva a cabo un estudio teórico-práctico de las variables que influyen tanto en el diseño del edificio en si mismo como en el espacio urbano resultante de tal intervención. El análisis de estos parámetros proporciona un punto de partida que permite concatenar y expandir un proceso que acaba delimitando su verdadera área física de influencia y las repercusiones que de ello se derivan para el ámbito público. Con el fin de evitar la paradoja de rehabilitar recintos que generen a su alrededor zonas desvitalizadas, y partiendo de la premisa de considerar la integración física (construir en contexto como punto clave para la verdadera regeneración de la zona, se asientan las bases para la implantación de políticas enfocadas hacia la dinamización en el ámbito local.

    In all industry type the health costs generated by the noise are high, because the noise can cause nuisance and to harm the capacity to work when causing tension and to perturb the concentration, and in more severe cases to reach to lose the sense of the hearing in the long term. The noise levels in the industry have been designated for the different types of use like residential, commercial, and industrial and silence areas. The noise can cause accidents when obstructing the communications and alarm signs. For this reason the noise should be controlled and mitigated, at a low level as reasonably is possible, taking into account that the noise is an acoustic contamination. The present study determines a bases line of the environmental noise levels in a nuclear power plant BWR-5 as Laguna Verde, (like reference) to be able to determine and to give pursuit to the possible solutions to eliminate or to limit the noise level in the different job areas. The noise levels were registered with a meter of integrative noise level (sonometer) and areas of noise exposure levels mapping the general areas in the buildings were established, being the registered maximum level of 96.94 dba in the building of the Reactor-elevation 0.65 m under the operation conditions of Extended Power Up rate (EPU) of 120% PTN. Knowing that the exposition to noises and the noise dose in the job place can influence in the health and in the safety of the workers, are extensive topics that they should be analyzed for separate as they are: to) the effects in the health of the exposure to the noise, b) how measuring the noise, c) the methods and technologies to combat and to control the noise in the industry by part of engineering area and d) the function of the industrial safety bodies as delegates of the health and safety in the task against the noise in the job.

    Wettability and interfacial interaction of the Ta2O5/Cu-Al system were studied. Pure Cu does not wet the Ta2O5 substrate, and improved spreading is achieved when relatively a high fraction of the active element (~40 at.% Al) was added. The Al2O3 and AlTaO4 phases were observed at the Ta2O5/Cu-Al interface. A thermodynamic evaluation allowed us to suggest that the lack of wetting bellow 40 at.% Al is due to the presence of a native oxide, which covers the drop. The conditions of the native oxide decomposition and the formation of the volatile Al2O suboxide strongly depend on the vacuum level during sessile drop experiments and the composition of the Cu-Al alloy. In our case, Al contents greater than 40% provides thermodynamic conditions for the formation of Al2O (as a result of Al reaction with Al2O3) and the drop spreading. It was suggested that the final contact angle in the Ta2O5/Cu-Al system (50°) is determined by Ta adsorption on the newly formed alumina interlayer.

    With a view to examine the possibility of estimating the content of entrapped metallic aluminium in the salt cake from aluminium remelting, the thermal diffusivity of reference composites of KCl-NaCl-Al was measured as a function of aluminium metal content at room temperature. The thermal conductivity of the reference composites was found to increase with the metallic Al content. The lumped parameter model approach was carried out to discuss the influence of different geometry arrangements of each phase, viz. air, salts and metallic aluminium on the thermal conductivity. Application of the present results to industrial samples indicates that factors such as the interfacial condition of metallic Al particles have to be considered in order to estimate the amount of entrapped Al in the salt cake.

Hence it is particularly important for this country to have a steady supply of water and electricity. To meet this need, large power stations have been built. Power station A is one of the various sources which provide Kuwait with electric power. It has four turboalternator units. Inside the building, a system of airconditioning has been developed, at such pressure and air speed that it will counteract outer climatic conditions and prevent the entry of sand particles into the power station during the frequent sandstorms. The external appearance of the power station has been carefully studied in order to bring it as much as possible into harmony with the surrounding buildings. The outline is audacious and irregular, seeking to obtain a variety of profiles and light and shade effects. It creates an impression that is reminiscent of the local mud structures, of simple and primitive shape, broken and rounded by the prolonged action of weather. Inside, the colour schemes are cool and relaxing whilst on the outside only those parts have been painted which are not likely to suffer the full effect of the sun.

Esta preocupación también llega al legislador que ha elaborado diferentes tipos de normativas que persiguen la protección de la salud humana y el medio ambiente. Los agentes físicos lesivos y tóxicos suelen agruparse según el tipo de energía en que se manifiesten: la energía mecánica, en forma de ruido y vibraciones; la energía calorífica; la presión y la gravedad; y la energía electromagnética, en la que se distinguen radiaciones ionizantes y no ionizantes. Las radiaciones ionizantes son las más peligrosas, siendo sus principales ámbitos normalizados la protección sanitaria de la población o de los trabajadores, el control de las exposiciones en usos médicos, de los traslados de sustancias radiactivas, de las fuentes radiactivas selladas de actividad elevada y de las fuentes huérfanas y de la contaminación de aguas y alimentos, así como la conservación de alimentos por irradiación. Las regulaciones sobre campos electromagnéticos persiguen la protección del público en general y de los trabajadores frente al riesgo eléctrico y electromagnético, la armonización del espectro radioeléctrico, la protección del dominio público radioeléctrico y el control de los equipos.

    Energy Technology Data Exchange (ETDEWEB)

    The industrial sector accounts for 40% of global energy use. In 1995, developing countries used an estimated 48 EJ for industrial production, over one-third of world total industrial primary energy use (Price et al., 1998). Industrial output and energy use in developing countries is dominated by China, India, and Brazil. China alone accounts for about 30 EJ (National Bureau of Statistics, 1999), or about 23% of world industrial energy use. China's industrial sector is extremely energy-intensive and accounted for almost 75% of the country's total energy use in 1997. Industrial energy use in China grew an average of 6.6% per year, from 14 EJ in 1985 to 30 EJ in 1997 (Sinton et al., 1996; National Bureau of Statistics, 1999). This growth is more than three times faster than the average growth that took place in the world during the past two decades. The industrial sector can be divided into light and heavy industry, reflecting the relative energy-intensity of the manufacturing processes. In China, about 80% of the energy used in the industrial sector is consumed by heavy industry. Of this, the largest energy-consuming industries are chemicals, ferrous metals, and building materials (Sinton et al., 1996). This paper presents the results of international comparisons of production levels and energy use in six energy-intensive subsectors: iron and steel, aluminum, cement, petroleum refining, ammonia, and ethylene. The sectoral analysis results indicate that energy requirements to produce a unit of raw material in China are often higher than industrialized countries for most of the products analyzed in this paper, reflecting a significant potential to continue to improve energy efficiency in heavy industry.

El desarrollo mantuvo su vigencia entre 1945 y 1975, cuando al advenimiento del neoliberalismo fue paulatinamente retirado de la agenda de las preocupaciones nacionales e internacionales. Al iniciarse el siglo xxi, el fracaso del mercado autorregulado trajo de nueva cuenta al debate los problemas del desarrollo, lo que obliga a revisarlo críticamente, tanto como al concepto mismo para mostrar su carácter colonial, si se quiere construir caminos ajenos al neoliberal y superar los problemas que han hecho de Latinoamérica una de las regiones más desiguales del mundo.

    The move-to-the-middle hypothesis has been used to predict firm structures, suggesting that firms will move to more outsourcing but from a reduced set of stable partners (Clemons et al., 1993). Extending this hypothesis to predict electronic marketplace structures, we suggest that both industry consortia and private exchanges represent a move to the middle by reducing transaction costs and risks. In industries with highly interdependent relationships, industry consortia may be more successful...

    Sich kontinuierlich verändernde Rahmenbedingungen, wie beispielsweise eine steigende Variantenvielfalt, verkürzte Produktlebenszyklen sowie Kundenforderungen nach höherer Qualität, kürzeren Lieferzeiten und geringeren Kosten, fordern von produzierenden Unternehmen eine stetige Anpassung der Prozesse, der Organisation und der Strukturen. Seit den 90er Jahren versuchen immer mehr deutsche Unternehmen diesen veränderten Anforderungen mit der Einführung eines Ganzheitlichen Produktionssystems (GPS) zu begegnen. Ganzheitliche Produktionssysteme sind dabei in ihren Grundlagen an das Toyota Produktionssystem angelehnt, vereinigen aber auch weitere Methoden zu einem unternehmensspezifischen Regelwerk. Im Rahmen des langfristigen Trends zu unternehmensindividuellen Produktionssystemen wird sowohl in der Industrie als auch in der Forschung intensiv über das Toyota Produktionssystem, Lean Production, Lean Management und Ganzheitliche Produktionssysteme diskutiert, werden Konzepte zu Implementierung und Betrieb erstellt und die Wirtschaftlichkeit untersucht.

MATERIAL Y MÉTODOS: Durante enero y febrero de 1997 se llevó a cabo un estudio transversal en una planta productora de cemento en el estado de Morelos. Se realizaron una sonometría, dosimetría y pruebas audiométricas a 85 trabajadores para identificar las fuentes que generan ruido en las áreas de proceso, evaluar los niveles de ruido en dichas áreas (monitoreo de área y de personal y para determinar la prevalencia de pérdida auditiva inducida por el ruido entre los trabajadores. Para el análisis estadístico se emplearon medidas de tendencia central, análisis bivariado y modelos de regresión politómica. RESULTADOS: En las áreas de trituración, molinos de crudo y molinos de cemento se encontraron niveles elevados de ruido. La dosis personal más alta correspondió al puesto de envasador. En 55% de la población estudiada se presentó pérdida auditiva inducida por el ruido, y el área de proceso con el porcentaje más alto de pérdida auditiva inducida por el ruido fue la de calcinación, con 85%. CONCLUSIONES: Los resultados mostraron que el ruido es un serio riesgo en algunas áreas, y que algunos casos de pérdida auditiva inducida por el ruido hayan sido desarrollados por exposición ocupacional en esta industria.

    Three major events are responsible for the rampancy today of Al Qaedaism, the doctrine of Al Qaeda, an Islam extremist organization. They are: the Anti-Soviet Afghanistan War for the birth of the group; the September 11 terrorist attacks for the spread of its extremist demagogy and the war on terror for its branches networking into alliances worldwide.Al Qaedaism aims at driving away Western forces on the Moslem lands, overthrowing local Pro-West regimes, destroying Israel and setting up a Caliphate empire. Its rampancy has resulted from a combination of diverse factors at work under specific historical conditions rather an inevitable outcome of the growth of the Islam religion.As an ideological weapon for launching Jihad to oust Western influence and topple local regimes, Al Qaedaism reflects an extremist portrayal of modern Islam society, politics, economy and culture.

CPGs are supposed to serve an important purpose. They offer objective consensus of expert opinion on treatment and hence are trusted by hospitals and practicing physicians alike. They can reduce the possibility of inappropriate care being delivered, while helping introduce new knowledge into clinical practice (Grimshaw and Russell, 1993; Merritt et al. , 1997; Woolf et al. , 1999. They are a distillate of biomedical wisdom at a certain point of time applied to better and more efficient patient care. Hence, rigorously developed guidelines can translate complicated research findings into actionable recommendations of clinical care (Shiffman et al. , 2003; Haines and Jones, 1994. Clinical practice guidelines have generally been accepted as an objective consensus on evidence (Baird, 2003. Practice guidelines approved by expert panels are intended to standardize care in such a way as to improve health outcomes (Eichacker et al. , 2006. Major hospitals and knowledge updated physicians feel reassured they are doing the very best by following CPGs. State of the art, and such other fancy labels, can be justifiably applied to them.McMaster et al., (2007 have talked recently of getting guidelines to work in practice. In an effort to make CPGs more effective, developers of such guidelines have started grouping evidence-based interventions into what are called 'bundles'. The justification for

    2015-01-01

    The leakage current behaviors of Al/ZrO2/Al and Al/yttria stabilized zirconia (YSZ)/Al devices are investigated for resistive random access memory (RRAM) applications. A silicon oxide layer (450 nm) is first formed on a Si wafer by thermal oxidation. Onto it an Al bottom electrode (270 nm), a ZrO2 or YSZ nano-film (75 nm), and an Al top electrode (270 nm) are sequentially deposited by sputtering. These RRAM devices exhibit ohmic behaviors in the low-field region, while Schottky and Poole-Frenkel emissions take over in the high-field regions. Both the Schottky and trap barrier levels are decreased when monoclinic ZrO2 is replaced by cubic YSZ in the metal/oxide/metal structure. This is attributed not only to the higher symmetry crystal structure and lower binding energy of YSZ, but also to the formation of more oxygen vacancies and their re-distribution associated with yttria doping.

    Because of their good mechanical properties at high temperatures and their low density, the intermetallic TiAl phase based alloys have great potential for a use in a range of industrial applications. Having a density of about 4 g/cm{sup 3}, TiAl-alloy components are about half of that of the weight of the high temperature resistant materials currently in use (nickel based alloys or steels). Depending upon the composition and manufacturing process used, a number of different microstructures can be adjusted for these alloys. In this article, the microstructures of different Ti and TiAl alloys ({alpha}-Ti, {alpha}{sub 2}-Ti{sub 3} Al, orthorhombic Ti{sub 2}AlNb and {gamma}-TiAl) were investigated using different etchants. In addition the alloys were also characterised using other analytical methods (scanning electron microscopy, electron probe microanalyser and X-ray diffraction). (orig.)

    The application of compound parts of Al-[AlBO]w/Al not only reduces the cost of the parts but also improves its properties. However, there is a large thermal residual stress between Al and [AlBO]w/Al, and it is harmful for practical application. From the theoretical analyses and experimental results, it was found that by the compressive pre-plastic deformation perpendicular to the interface between Al and [AlBO]w/Al, the interlayer residual stress of compound parts can be reduced, while the mechanical properties of compound parts can be improved.

Employment in the rubber industry has been associated with bladder cancer, leukemia, stomach, and lung cancer and is considered by the International Agency for Research on Cancer (IARC) to have 'sufficient evidence of carcinogenicity in humans.' Studies of workers exposed to polychlorinated biphenyls (PCBs) have reported excess mortality from gastrointestinal neoplasms, hematologic neoplasms, and skin cancer (specifically malignant melanoma); IARC considers that the evidence for carcinogenicity in humans is 'limited.' Employment in the boot and shoe industry has been associated with nasal adenocarcinomas in England and Italy ('sufficient'). Hairdressers and barbers have been found to have excess bladder cancer and less consistent evidence for several other sites ('limited'). Workers exposed to wood dust have excess mortality from cancer of the nasal sinuses and paranasal cavities; there is less consistent evidence for excess laryngeal cancer ('sufficient'). Workers employed in the petroleum industry have limited evidence for excess leukemia and other lymphatic and hematopoietic neoplasms, and skin cancer (particularly malignant melanoma) ('limited').

    Microelectronics industry leaders routinely name mask cost and cycle time as top issues of concern. A survey was created with support from International SEMATECH (ISMT) and administered by SEMI North America to gather information about the mask industry as an objective assessment of its overall condition. The survey is designed with the input of mask technologists from semiconductor manufacturers, merchant mask suppliers, and makers of equipment for mask fabrication. This year's assessment is the third in the current series of annual reports and is intended to be used as a baseline for the mask industry and the microelectronics industry to gain a perspective on the technical and business status of the mask industry. This report will continue to serve as a valuable reference to identify the strengths and opportunities of the mask industry. The results may be used to guide future investments on critical path issues. This year's survey builds upon the 2003 survey to provide an ongoing database using the same questions as a baseline with only a few minor changes or additions. Questions are grouped into categories: general business profile information, data processing, yields and yield loss mechanisms, delivery times, returns and services. Within each category are a many questions that create a detailed profile of both the business and technical status of the mask industry. This assessment includes inputs from ten major global merchant and captive mask manufacturers whose revenue represents approximately 85% of the global mask market.

The stable structures and electronic properties of AlCl, AlCl2 and AlCl3 adsorbed on Al4CO4, Al2CO and Al4C3 were calculated by first-principles calculations by the CASTEP module in the Materials Studio program. The results show that the AlCl3 and AlCl2 molecules have decomposed on the plane of Al4C3 (001), while there are no obvious decomposition of AlCl3 and AlCl2 on Al4CO4 (001) and Al2CO (001) planes. The adsorption of AlCl on the Al4CO4 (001) and Al2CO (001) planes is stronger than that on the Al4C3(001) plane. The interaction strength of AlCl3, as well as AlCl2, with Al4CO4, Al2CO and Al4C3 is in the sequence of Al4CO4Al2CO>Al4C3.

    Microelectronics industry leaders routinely name mask technology and mask supply issues of cost and cycle time as top issues of concern. A survey was initiated in 2002 with support from International SEMATECH (ISMT) and administered by SEMI North America to gather information about the mask industry as an objective assessment of its overall condition.1 This paper presents the results of the second annual survey which is an enhanced version of the inaugural survey building upon its strengths and improving the weak points. The original survey was designed with the input of member company mask technologists, merchant mask suppliers, and industry equipment makers. The assessment is intended to be used as a baseline for the mask industry and the microelectronics industry to gain a perspective on the technical and business status of the critical mask industry. An objective is to create a valuable reference to identify strengths and opportunities and to guide investments on critical-path issues. As subsequent years are added, historical profiles can also be created. This assessment includes inputs from ten major global merchant and captive mask manufacturers representing approximately 80% of the global mask market (using revenue as the measure) and making this the most comprehensive mask industry survey ever. The participating companies are: Compugraphics, Dai Nippon Printing, Dupont Photomask, Hoya, IBM, Infineon, Intel, Taiwan Mask Company, Toppan, and TSMC. Questions are grouped into five categories: General Business Profile Information; Data Processing; Yields and Yield loss Mechanisms; Delivery Time; and Returns and Services. Within each category are a multitude of questions that create a detailed profile of both the business and technical status of the mask industry.

  1. Industrial services at CERN

    CERN Multimedia

    2002-01-01

    The Bulletin looks at industrial services contracts and the real impact of the cost reductions at CERN. The level of industrial services contracts varies from one phase to another. For example, during the dismantling of LEP (photo) it rose substiantially to fall again at the end of dismantling. Industrial services contracts are an important resource for CERN. The level and nature of such contracts changes according to the phase of operation of the Laboratory. A construction phase, as for the LHC, requires a higher level of industrial services contracts compared with a period of normal running. During the operation of LEP, industrial services contracts were thus maintained at a level of 120 MCHF per year. The level rose to 156 MCHF in 2001 to include contracts awarded for dismantling LEP, and fell to about 144 MCHF in 2002 when the dismantling was complete. During the whole LHC construction period, up to 2007, industrial services spending will be stable in the range 135-140 MCHF per year. For the running pe...

    2012-07-07

    Graphene is an allotrope of carbon whose structure is based on one-atom-thick planar sheets of carbon atoms that are densely packed in a honeycomb crystal lattice. Its unique electrical and optical properties raised worldwide interest towards the design and fabrication of future electronic and optical devices with unmatched performance. At the moment, extensive efforts are underway to evaluate the reliability and performance of a number of such devices. With the recent advances in synthesizing large-area graphene sheets, engineers have begun investigating viable methodologies for conducting graphene metrology and quality control at industrial scales to understand a variety of reliability issues including defects, patternability, electrical, and physical properties. This review summarizes the current state of industrial graphene metrology and provides an overview of graphene metrology techniques. In addition, a recently developed large-area graphene metrology technique based on fluorescence quenching is introduced. For each metrology technique, the industrial metrics it measures are identified--layer thickness, edge structure, defects, Fermi level, and thermal conductivity--and a detailed description is provided as to how the measurements are performed. Additionally, the potential advantages of each technique for industrial use are identified, including throughput, scalability, sensitivity to substrate/environment, and on their demonstrated ability to achieve quantified results. The recently developed fluorescence-quenching metrology technique is shown to meet all the necessary criteria for industrial applications, rendering it the first industry-ready graphene metrology technique.

  3. Contradictions of industrial policy

    Energy Technology Data Exchange (ETDEWEB)

    Levitan, S.A.; Johnson, C.M.

    1983-01-01

    The authors feel that proposals for a new industrial policy have remained unfocused and their most constructive elements have been ignored. If industrial policy arguments emerged from another political context - as a vindication of government intervention instead of an alternative to it - the potential of such arguments for improving economic performance and industrial competitiveness would be considerably greater. Instead, industrial policy has sprouted from a neoliberal movement which in large measure accepts the notion that government intervention has contributed to our social and economic problems. The authors conclude that a constructive approach requires that we abandon the popular widsom that claims our social programs have failed. On the contrary, it requires that we heed evidence demonstrating that societal investments in education, training, and employment pay off. Further, concrete solutions to our economic and social problems will emerge only if proponents of industrial policy acknowledge - openly, vocally, and unabashedly - the importance of an expanded role for government. When industrial policy advocates address this underlying issue, they will build support for necessary public investments that could capture the returns associated with an adaptable workforce, a strong scientific base, and a sound infrastructure for commerce and trade.

This report will continue to serve as a valuable reference to identify the strengths and opportunities of the mask industry. The results may be used to guide future investments on critical path issues. This year's survey contains all of the 2004 survey questions to provide an ongoing database. Additional questions were added to the survey covering operating cost factors and equipment utilization. Questions are grouped into categories: general business profile information, data processing, yields and yield loss mechanisms, delivery times, returns and services, operating cost factors and equipment utilization. Within each category are a many questions that create a detailed profile of both the business and technical status of the mask industry.

    Over the years this conference has gained a solid reputation as an appropriate rostrum for illustrating new concepts in the relations between industry and the scientific world and for introducing new technologies to a large assistance of junior and more experienced scientists. In fact, from the very beginning the founders of this endeavour announced: "The conference is aimed for promoting contacts among scientists involved in particle and fundamental physics, among experimental physicists in other fields and representatives from industry." Facilities at the Conference are designed to fulfil the task: space and general facilities are offered to industry representatives to display their products. This year a more accessible and luminous space arrangement was made available to the exhibitors. At the same time two plenary sessions have been dedicated to selected speakers to illustrate new trends in Technology Transfer, analysis of environment affecting our community, examples of historical successes in the merging of science and industry. We have identified in "GRID" and in "E-Publishing" two major promising areas where our Community will play a prime role as "User" and it was of the general interest to have them illustrated by two personalities directly involved in their development. The flow of knowledge is of course more massive from "Industry" to "Science" than vice-versa, but "Science" to "Industry" move offers an intensive added value. The technology transfer concept with the "Patents" as fund raising tool proved less glorious than expected. Trademark, licensing agreement and " Patents" can assure intellectual properties. But patent is an issue to be used cautiously. Evidence exists that much more efficient transfer of "Science" knowledge to "Economy" is achieved by venture capital move and start-up companies. These two facets of the Technology Transfer business have been covered by Routti's and Bourgeois's lectures.There are two examples of Companies who moved

  14. Canadian construction industry

    2001-07-01

    The principal sectors of the Canadian construction industry - commercial, industrial, institutional and residential - are examined with regard to their technical considerations concerning the subject of sustainability. Apart from the different needs of each of the sectors of the industry there are also regional differences caused by population distribution, and differences in climate, that have to be identified and accommodated in considering attitudes to recycling and sustainable development. Some indications that there is growing awareness of recycling and reuse are: the increasing frequency of life cycle costing in the commercial and institutional sectors, the use of recycled or otherwise waste materials in concrete, examples of using steel supporting structures and roof joists salvaged from previous uncompleted projects in the industrial sector, improved building envelope and indoor air quality concerns, collective ground source heating, and new basement and framing technologies and construction materials in the residential sector. These improvements notwithstanding, there remains much to be done. The new objective-based National Building Code, for which comments are now being solicited across the country, is expected to identify new and innovative solutions and to kick-start serious efforts to come up with solutions towards increasing overall sustainability in all sectors of the Canadian construction industry.

  15. Doctors and pharmaceutical industry.

    Science.gov (United States)

    Beran, Roy G

    2009-09-01

    The pharmaceutical industry is seen as seducing doctors by providing expensive gifts, subsidising travel and underwriting practice expenses in return for those doctors prescribing products that otherwise they would not use. This paints doctors in a very negative light; suggests doctors are available to the highest bidder; implies doctors do not adequately act as independent agents; and that doctors are driven more by self-interest than by patient needs. Similar practices, in other industries, are accepted as normal business behaviour but it is automatically assumed to be improper if the pharmaceutical industry supports doctors. Should the pharmaceutical industry withdraw educational grants then there would be: fewer scientific meetings; reduced attendance at conferences; limited post graduate education; and a depreciated level of maintenance of professional standards. To suggest that doctors prescribe inappropriately in return for largesse maligns their integrity but where there is no scientific reason to choose between different treatments then there can be little argument against selecting the product manufactured by a company that has invested in the doctor and the question arises as to whether this represents bad medicine? This paper will examine what constitutes non-professional conduct in response to inducements by the pharmaceutical industry. It will review: conflict of interest; relationships between doctors and pharma and the consequences for patients; and the need for critical appraisal before automatically decrying this relationship while accepting that there remain those who do not practice ethical medicine.

    The evolution of iron (Fe) bearing intermetallics (Fe-IMCs) during direct chill casting and homogenization of a grain-refined 6063 aluminum-magnesium-silicon (Al-Mg-Si) alloy has been studied. The as-cast and homogenized microstructure contained Fe-IMCs at the grain boundaries and within Al grains. The primary α-Al grain size, α-Al dendritic arm spacing, IMC particle size, and IMC three-dimensional (3D) inter-connectivity increased from the edge to the center of the as-cast billet; both α c-AlFeSi and β-AlFeSi Fe-IMCs were identified, and overall α c-AlFeSi was predominant. For the first time in industrial billets, the different Fe-rich IMCs have been characterized into types based on their 3D chemistry and morphology. Additionally, the role of β-AlFeSi in nucleating Mg2Si particles has been identified. After homogenization, α c-AlFeSi predominated across the entire billet cross section, with marked changes in the 3D morphology and strong reductions in inter-connectivity, both supporting a recovery in alloy ductility.

    This presentation by Norway`s Minister of Petroleum and Energy describes (1) Norway in the energy picture, (2) oil market developments, (3) the establishment of an energy policy and (4) the investment level of the Norwegian petroleum activities. Value creation from Norwegian petroleum resources is directly connected with the commercial companies` participation in the activities. Thus, it has been a main challenge for Norway to establish a balanced petroleum policy and a legal framework. Presumably Norway will remain a prospective and attractive petroleum province for a long time. Over the years, Norway has developed three very competent and competitive national oil companies and a significant national supply industry. This industry is highly competitive internationally. Many new petroleum provinces are opening up for foreign investors and energy consumption of the world is expected to increase significantly the next 20 - 30 years. This implies increased demand for the products, but also strong competition for industry resources

  4. Emulsified industrial oils recycling

    Energy Technology Data Exchange (ETDEWEB)

    Gabris, T.

    1982-04-01

    The industrial lubricant market has been analyzed with emphasis on current and/or developing recycling and re-refining technologies. This task has been performed for the United States and other industrialized countries, specifically France, West Germany, Italy and Japan. Attention has been focused at emulsion-type fluids regardless of the industrial application involved. It was found that emulsion-type fluids in the United States represent a much higher percentage of the total fluids used than in other industrialized countries. While recycling is an active matter explored by the industry, re-refining is rather a result of other issues than the mere fact that oil can be regenerated from a used industrial emulsion. To extend the longevity of an emulsion is a logical step to keep expenses down by using the emulsion as long as possible. There is, however, another important factor influencing this issue: regulations governing the disposal of such fluids. The ecological question, the respect for nature and the natural balances, is often seen now as everybody's task. Regulations forbid dumping used emulsions in the environment without prior treatment of the water phase and separation of the oil phase. This is a costly procedure, so recycling is attractive since it postpones the problem. It is questionable whether re-refining of these emulsions - as a business - could stand on its own if these emulsions did not have to be taken apart for disposal purposes. Once the emulsion is separated into a water and an oil phase, however, re-refining of the oil does become economical.

  12. Industrial cogeneration optimization program

    Energy Technology Data Exchange (ETDEWEB)

    1980-01-01

    The purpose of this program was to identify up to 10 good near-term opportunities for cogeneration in 5 major energy-consuming industries which produce food, textiles, paper, chemicals, and refined petroleum; select, characterize, and optimize cogeneration systems for these identified opportunities to achieve maximum energy savings for minimum investment using currently available components of cogenerating systems; and to identify technical, institutional, and regulatory obstacles hindering the use of industrial cogeneration systems. The analysis methods used and results obtained are described. Plants with fuel demands from 100,000 Btu/h to 3 x 10/sup 6/ Btu/h were considered. It was concluded that the major impediments to industrial cogeneration are financial, e.g., high capital investment and high charges by electric utilities during short-term cogeneration facility outages. In the plants considered an average energy savings from cogeneration of 15 to 18% compared to separate generation of process steam and electric power was calculated. On a national basis for the 5 industries considered, this extrapolates to saving 1.3 to 1.6 quads per yr or between 630,000 to 750,000 bbl/d of oil. Properly applied, federal activity can do much to realize a substantial fraction of this potential by lowering the barriers to cogeneration and by stimulating wider implementation of this technology.

In biotechnological processes different microorganisms can be exploited, and the large diversity of metabolic reactions represents a rich repository for the design of chemical conversion processes that lead to efficient production of desirable products. However, often microorganisms that produce a desirable product, either naturally or because they have been engineered through insertion of heterologous pathways, have low yields and productivities, and in order to establish an economically viable process it is necessary to improve the performance of the microorganism. Here metabolic engineering is the enabling technology. Through metabolic engineering the metabolic landscape of the microorganism is engineered such that there is an efficient conversion of the raw material, typically glucose, to the product of interest. This process may involve both insertion of new enzymes activities, deletion of existing enzyme activities, but often also deregulation of existing regulatory structures operating in the cell. In order to rapidly identify the optimal metabolic engineering strategy the industry is to an increasing extent looking into the use of tools from systems biology. This involves both x-ome technologies such as transcriptome, proteome, metabolome, and fluxome analysis, and advanced mathematical modeling tools such as genome-scale metabolic modeling. Here we look into the history of these different techniques and review how they find application in industrial biotechnology, which will lead to what we here define as industrial systems biology.

    Industrial transformation represents a unique economic phenomenon in China's regional economy,and old industrial city reconstruction has long been a key problem that affects state security. As a typical old indus-trial city in China, Shenyang established its heavy industrial city position in the First Five-year Plan period (1953-1957), and this industrial structure has been consolidated for a long time. After 1978, Shenyang began its long last-ing industrial reconstruction in an all-round way by 3 main initiatives including restructuring economic system, up-grading traditional industrial technology and developing high-tech industry. In the end of the 1990s, it could be I-dentified that remarkable structural changes took place in city economy at large as well as individual industrial sec-tor. According to the GDP proportion change, Shenyang is on the way to a high level industrial structure. The sec-ondary industry also engendered significant shifting as smelting and textile industry declined sharply but IT industry increased largely. Although the ratio of the heavy industry to the light industry changed periodically, the heavy in-dustrial output value most time kept a high proportion over 60% of the gross industrial output value in the past five decades. Shenyang has favorable conditions for developing equipment manufacturing industry, but it should carry out the program by establishing its leading role in urban economy plan, building "Theme Industrial Parks", improv-ing Tiexi Industrial Zone, removing any kind of system barrier, enlarging private and other ownerships economy and improving technology, marketing and management by IT application. In response to economy globalization,Shenyang needs to expand the cooperation worldwide and improve the cohesion with surrounding cities.

    The Industrial Agglomeration Theory has been evolving all the time. The study on the industrial location has become the focus of the massive theoretical location problems about agglomeration since the 1970s. The authors here analyze the evolution and the characteristics of the Industrial Agglomeration Theory and study its effect on the reconstruction of industrial location. The study suggests that the new idea of reconstruction of industrial location is to cultivate regional innovative system. On this basis, the authors analyze two cases of old industrial bases on their construction-Tiexi Industrial District in Shenyang City and Changchun Industrial Economic Development Zone. Finally, the authors put forward some suggestions that should be regarded, which include: 1) to combine industrial location reconstruction and enterprises' inner reform; 2) to speed up adjustment of resources and opening to the world; 3) to combine government mechanism with the market mechanism properly.

    Full Text Available Historical mass media and contemporary social media are typically seen as opposites. “The culture industry” was the term used by the Frankfurt School in the 1940s to explain the emerging commercial mass media. The culture industry was portrayed as a semi-fascist apparatus of indoctrination. It selected cultural products and made them popular based on obscure determinations of economic value. In contrast, the common view of contemporary social media is that it is more democratic. Using voting algorithms and human voting, social media can finally realize widespread participation that was denied to the passive audiences of the mass media system. Social media appear to remove the bottleneck of the mass media system, allowing everyone to aspire to celebrity, or at least popularity. However, despite these appearances, social media have also now evolved into an elaborate system that selects social products and makes them popular based on obscure determinations of economic value. Social media platforms filter, censor, control, and train—and they may do so without the user’s awareness. Advances in computation now make a social media industry possible that is based on individual difference and action rather than sameness and passivity. But in other respects, the social industry resembles the culture industry: the co-option of culture has been superseded by the co-option of sociality. The word “social” may then be the biggest challenge facing those who study social media. Our task is to rescue genuine sociality from the emerging social industry.

    Con toda consideración y respeto me permito agregar algunas anotaciones al escrito del Académico Alberto Cárdenas Escobar, aparecido en el No. 22 de Medicina, para destacar algunos aspectos de la personalidad del doctor Alberto Schweitzer galardonado con el Premio Nobel de la Paz.

    A los 30 años de edad tomó una decisión dramática: Estudiar Medicina para trabajaren el África Ecuatorial. Cuando terminó sus investigaciones sobre enfermedades tropicales y sus prácticas hospitaLarias, partió para el Gabon al pequeño pueblo de Lambarené. La tarea era desconsoladora; La atención médica había que prestarla al aire libre; iba con su esposa, como enfermera y amanuense, y no se encontraba ni un intérprete, ni un ayudante. Cuando le llegaron la medicina y el equipaje hubo que acomodarlos en un viejo gallinero abandonado; el calor era insoportable y le venían enfermos de varias millas a la redonda, a pie o en Canoas.

    Las enfermedades más difundidas eran Malaria, Disentería, estreptococias y la más mortífera, la Tripanosomiasis Gambiense, para la que empezaban a llegar medicinas nuevas eficaces y las medidas preventivas como el suministro de agua potable y enmallado de ventanas impedían muchas contaminaciones.

    Pero la que causaba mayores dificultades y trabajo era la Mycobacteriasis Anestesiante, incurable, de difícil diagnóstico, afectando a varios miembros de la misma familia, de aspecto horripilante, con complicaciones neuríticas muy dolorosas, frecuente ceguera, e invalideces y procesos erisepelatososacrotéricos, que exigían acompañante para el cambio y lavado de vendas y suministro de alimentos.

    Congedo, Tom; Lahoda, Edward; Matzie, Regis; Task, Keith

    The objective of the nuclear industry is to pro-duce energy in the forms of heat from either fission reactions or radioactive decay and radiation from radioactive decay or by accelerator methods. For fission heat applications, the nuclear fuel has a very high specific energy content that currently has two principal uses, for military explosives and for electricity generation. As higher temperature reactors become more widely available, the high temperature heat (>900°C) will also be useful for making chemicals such as hydrogen. For radiation applications, the emissions from radioactive decay of unstable nuclides are employed in research, medicine, and industry for diagnostic purposes and for chemical reaction initiation. Radioactive decay heat is also employed to generate electricity from thermoelectric generators for low-power applications in space or remote terrestrial locations.

    1997-12-31

    This paper describes the cement and concrete industry, and provides data on energy use and carbon dioxide emissions. The potential impact of an energy tax on the industry is briefly assessed. Opportunities identified for reducing carbon dioxide emissions include improved energy efficiency, alternative fuels, and alternative materials. The key factor in determining CO{sub 2} emissions is the level of domestic production. The projected improvement in energy efficiency and the relatively slow growth in domestic shipments indicate that CO{sub 2} emissions in 2000 should be about 5% above the 1990 target. However, due to the cyclical nature of cement demand, emissions will probably be above target levels during peak demand and below target levels during demand troughs. 7 figs., 2 tabs.

    2014-01-01

    Full Text Available Swine effluent with high organic strength need to be treated to make it suitable for applying to crop/pasture fields, or discharging to any waterways. Electrocoagulation is a relatively simpler and cheaper technique over biological and chemical treatment methods currently used to treat high-strength industrial and municipal wastewater. The performance of an electrocoagulation system mainly depends on the pH, Electrical Conductivity (EC of the medium, Chemical Oxygen Demand (COD loading rates and catalytic activity of the electrodes used. In this research, a study was conducted to compare the pollutant removal efficiencies of three electrodes (Fe-Fe, Al-Al and Fe-Al with three electric current levels (500, 1000 and 2000 mA while treating swine manure effluents. The electrochemical cell consisted of two parallel rectangular plates (90×25×1.5 mm of Iron (Fe-Fe, Aluminum (Al-Al and Iron-Aluminum (Fe-Al, later on described as hybrid electrodes; immersed in a beaker with 550 mL swine effluents and powered by a Direct Current (DC supply. All studies were conducted in batches at room temperature. In general, removal efficiencies were increased with increasing current densities and electrolysis times for electrodes evaluated. Aluminum electrodes outperformed iron and hybrid (iron-aluminum electrodes in removing Total Phosphorus (TP at all current density levels tested. Overall, use of hybrid electrodes resulted in better COD removal. For the same treatment times (1200 s at higher current density (21 mA cm-2, hybrid electrodes removed about 100% COD, which are about 1.9 and 1.3 times higher than those of aluminum and iron electrodes, respectively. Iron electrodes showed the highest removal efficiency (85% for Total Organic Carbon (TOC at 21 mA cm-2 current density and 1200 s treatment time. Overall, lower Specific Electrical Energy Consumptions (SEECs per kg of Pollutants (TP, COD and TOC were estimated for the aluminum

    2000-01-01

    As a newly developing superplastic aluminum alloy, Al-Ca alloy has been widely used in industry, however thetechnology for preparing Al-Ca master alloy and its influencing factors need to be further studied. Therefore the Al-Camaster alloy was prepared by using liquid aluminum cathode and a mixture of 80%CaC12-18% KC1-2%CaF2 as the moltensalt electrolysis in a laboratory electrolyte cell; the effects of electrolysis temperature, cathodic current density and electrolytic duration on current efficiency and Ca content of Al-Ca alloy as well were studied. Through laboratory experiments, the parameters for smooth electrolytic reaction were proposed. The proper electrolysis technology is as follows:with the 80%CaCl2-18%KCl-2%CaF2 electrolyte, the electrolytic temperature is 973 K and the cathodic current densityis 0.8 A/cm2, the electrolysis can go on smoothly and a calcium content of 17.5%(mass fraction) can be obtained. Withthe increase of electrolysis duration, the calcium content in the alloy increasas whereas the current efficiency decreases

    Full Text Available En todas las revistas biomédicas del mundo existe una sección habitual denominada como el título de este editorial y que en Colombia Médica la llamamos correspondencia. Este espacio tiene como objetivo fundamental que los lectores escriban a los autores (investigadores comentando los artículos que se han publicado en números anteriores de la revista. Las cartas son, entonces, breves comentarios de desacuerdo o acuerdo (conceptual, metodológico, interpretativo sobre falencias ubicadas por un lector alerta al tema debatido en cualquiera de las secciones como en los artículos originales, editoriales, revisiones, presentación de casos, etc. publicados previamente en la revista. Las cartas deben permitir el intercambio de opiniones y formas de pensar y analizar los problemas planteados entre los autores y los lectores. En ocasiones una serie de cartas motivadas por un artículo original puede ser tan o más interesante como el artículo que generó la correspondencia. Las cartas son también un formato adecuado para comunicar un hecho novedoso de una observación clínica juiciosa no descrita antes. Un ejemplo de ello es la carta de un gineco-obstetra australiano cuando informó a Lancet los primeros efectos adversos informados de la talidomida. Colombia Médica, a pesar de mantener vigente esta sección, no ha sido muy afortunada en establecer una buena cultura del envío de cartas al editor. Pero últimamente han llegado juiciosas observaciones a las cuales se les ha dado prioridad en su publicación. Toda carta que comenta los hallazgos de un artículo es enviada a los autores para su respuesta, porque ello genera el debate académico buscado, y luego se publican, tanto la carta como su respuesta. El Estilo Vancouver recomienda que la carta y su respuesta deban ser breve, no pasar de dos o tres párrafos y contener sólo cuatro o cinco referencias.

    Full Text Available The needs for construction industry development are initially viewed from the broader perspectives of imperatives for infrastructure development and national development. All these are clearly more critical in developing countries. A non-exhaustive set of potential drivers and common barriers to construction industry development is identified from previous research. These suggest the usefulness of consolidating a cluster of recent proposals and exercises aiming at (a construction organization development in terms of an over-arching management support system model, as well as improved information and knowledge management; and (b project team development in the context of relationally integrated teams and supply chains, joint risk management and ‘technology and knowledge exchange’ in joint ventures, as well as longer term public private partnerships. These apparently disparate research thrusts are threaded together into a pattern that may inspire, if not feed, specific research and development (R & D agendas for construction industry development in different countries according to their own priorities, constraints and stages of infrastructure and national development.

  18. Icons of Industrial Design

    Directory of Open Access Journals (Sweden)

    Dominika Lušin

    2011-12-01

    Full Text Available An icon of industrial design is a product characterized by its usability and good permanent design and that simultaneously functions as a bearer of a cultural meaning. These meanings do not originate from the product itself, or its aesthetics, shape, or function, but are formed in the context of wider social and cultural processes. Stuart Hall’s “Circuit of Culture” concept is a model for explaining the cultural processes that form a product’s meaning. These processes are representation, identity, production, consumption, and regulation. Design discourses—for example, discourse about the design profession and good design discourse—need to be taken into consideration in order to understand some of the icons of industrial design. A product can have a special meaning merely because it is signed by a famous designer or because it is declared to be an example of good design. This is also a reason why an item can be included in a museum collection. This is a framework to research and to understand icons of industrial design, such as the Thonet chair no. 14, Savoy vase, Vespa, Rex chair, Braun SK 4, Juicy Salif, and design artifacts in general.

Es kann nur durch die Zurverfügungstellung und allgemeine Veröffentlichung erreicht werden. Historisch betrachtet konnte man immaterielle Eigentumsrechte nicht erwerben, wenn man keinen Verleger fand. Erst in den letzten Jahren wurde es sehr einfach, durch die Veröffentlichung unseres Wissens im Internet, zu geistigem Eigentum zu gelangen. Die Ursache für diese Eigenschaft geistigen Eigentums ist die Informationstheorie, in der Informationen in beliebiger Menge zu Redundanz kopiert werden kann. An dieser Stelle spielen die Verlage noch immer eine wichtige Rolle, durch ihre Anzeige ausgewählter Immaterialgüterrechte von Autoren oder Interessengruppen.Abstract: Intellectual property is characterized by a remarkable attribute. It has to be made available for the world by publication. In earlier times one couldn’t achieve intangible property rights if there was no publisher available. Only in recent years it became very easy to get intellectual properties by publishing our knowledge in the Internet. The cause for such a strange fact is the information theory, in which information can be copied to redundancy in any quantity. A growing problem is the amount of publications in which the identification of individual contributions is more and more difficult. At this point, the publishing industry plays till now an important role by advertising intellectual properties of selected authors or special interest groups.

This status report summarizes the work on industry outreach that has been completed since the inception of the project in October 1994. A three-pronged approach was taken to ascertain issues related to industry outreach. First, there was a review of on-going and past industry outreach activities at DOE and NHA. Next, a series of meetings with industry decision makers was arranged to get a better understanding of industry interests and concerns, and to discuss how DOE and industry could work collaboratively to develop hydrogen energy systems. Third, a workshop is scheduled where representatives from industry, DOE and other federal agencies can identify issues that would enhance partnering between the federal government and industry in the development of hydrogen energy systems. At this tiny, the review of on-going and past activities has been completed. Industry interviews are in progress and a majority of meetings have been held. Analysis of the information gained is in progress. The preliminary analysis of this information indicates that for appropriate near-term demonstration-type projects, the level of interest for collaboration between DOE and industry is high. The data also identifies issues industry is concerned with which impact the commercialization of hydrogen energy systems.

    Programmable logic controllers (PLCs) have very limited diagnostic and no prognostic capabilities, while current smart sensor designs do not have the capability to communicate over Fieldbus networks. The aim is to interface smart sensors with PLCs so that health and status information, such as failure mode identification and measurement tolerance, can be communicated via an industrial Fieldbus such as ControlNet. The SNE Industrial Fieldbus Interface (SIFI) is an embedded device that acts as a communication module in a networked smart sensor. The purpose is to enable a smart sensor to communicate health and status information to other devices, such as PLCs, via an industrial Fieldbus networking protocol. The SNE (Smart Network Element) is attached to a commercial off-the-shelf Any bus-S interface module through the SIFI. Numerous Anybus-S modules are available, each one designed to interface with a specific Fieldbus. Development of the SIFI focused on communications using the ControlNet protocol, but any of the Anybus-S modules can be used. The SIFI communicates with the Any-bus module via a data buffer and mailbox system on the Anybus module, and supplies power to the module. The Anybus module transmits and receives data on the Fieldbus using the proper protocol. The SIFI is intended to be connected to other existing SNE modules in order to monitor the health and status of a transducer. The SIFI can also monitor aspects of its own health using an onboard watchdog timer and voltage monitors. The SIFI also has the hardware to drive a touchscreen LCD (liquid crystal display) unit for manual configuration and status monitoring.

    In FeSiAl alloys, when Si substitutes for Al, important changes take place in the magnetism as well as in the structural properties. Alloys in the two composition series Fe{sub 75}Al{sub 25-x}Si{sub x} (x=0, 7.5, 12.5, 17.5, 25) and Fe{sub 70}Al{sub 30-x}Si{sub x} (x=0, 9, 15, 21, 30) were prepared by induction melting; afterwards they were crushed and then annealed in order to recover the DO{sub 3} stable phase. The deformed FeAl samples show larger lattice parameters than the ordered ones; however, this difference ({delta}a) decreases when Si substitutes for Al until it becomes zero (i.e. until the ordered samples and the deformed ones have the same lattice parameters). This trend is the same for both sample series and does not depend on the Fe content of the alloy. However, the magnetization has a different behaviour depending on the Fe content. For deformed Fe{sub 75}Al{sub 25-x}Si{sub x} alloys the saturation magnetization decreases with increasing Si content while for Fe{sub 70}Al{sub 30-x}Si{sub x} deformed alloys the saturation magnetization has a plateau in which the saturation magnetization values do not vary.

    Industrial sources are among the least documented PM (Particulate Matter) source in terms of chemical composition, which limits our understanding of their effective impact on ambient PM concentrations. We report 4 chemical emission profiles of PM2.5 for multiple activities located in a vast metallurgical complex. Emissions profiles were calculated as the difference of species concentrations between an upwind and a downwind site normalized by the absolute PM2.5 enrichment between both sites. We characterized the PM2.5 emissions profiles of the industrial activities related to the cast iron (complex 1) and the iron ore conversion processes (complex 2), as well as 2 storage areas: a blast furnace slag area (complex 3) and an ore terminal (complex 4). PM2.5 major fractions (Organic Carbon (OC) and Elemental Carbon (EC), major ions), organic markers as well as metals/trace elements are reported for the 4 industrial complexes. Among the trace elements, iron is the most emitted for the complex 1 (146.0 mg g-1 of PM2.5), the complex 2 (70.07 mg g-1) and the complex 3 (124.4 mg g-1) followed by Al, Mn and Zn. A strong emission of Polycyclic Aromatic Hydrocarbons (PAH), representing 1.3% of the Organic Matter (OM), is observed for the iron ore transformation complex (complex 2) which merges the activities of coke and iron sinter production and the blast furnace processes. In addition to unsubstituted PAHs, sulfur containing PAHs (SPAHs) are also significantly emitted (between 0.011 and 0.068 mg g-1) by the complex 2 and could become very useful organic markers of steel industry activities. For the complexes 1 and 2 (cast iron and iron ore converters), a strong fraction of sulfate ranging from 0.284 to 0.336 g g-1) and only partially neutralized by ammonium, is observed indicating that sulfates, if not directly emitted by the industrial activity, are formed very quickly in the plume. Emission from complex 4 (Ore terminal) are characterized by high contribution of Al (125.7 mg

    The feasibility of producing hydrogen from various industrial wastes, such as vinasses (sugar and tequila industries), and raw and physicochemical-treated wastewater from the plastic industry and toilet aircraft wastewater, was evaluated. The results showed that the tequila vinasses presented the maximum hydrogen generation potential, followed by the raw plastic industry wastewater, aircraft wastewater, and physicochemical-treated wastewater from the plastic industry and sugar vinasses, respectively. The hydrogen production from the aircraft wastewater was increased by the adaptation of the microorganisms in the anaerobic sequencing batch reactor.

    Industrial biotechnology involves the use of enzymes and microorganisms to produce value-added chemicals from renewable sources. Because of its association with reduced energy consumption, greenhouse gas emissions, and waste generation, industrial biotechnology is a rapidly growing field. Here we highlight a variety of important tools for industrial biotechnology, including protein engineering, metabolic engineering, synthetic biology, systems biology, and downstream processing. In addition, we show how these tools have been successfully applied in several case studies, including the production of 1, 3-propanediol, lactic acid, and biofuels. It is expected that industrial biotechnology will be increasingly adopted by chemical, pharmaceutical, food, and agricultural industries.

    We study the structure of inter-industry relationships using networks of money flows between industries in 20 national economies. We find these networks vary around a typical structure characterized by a Weibull link weight distribution, exponential industry size distribution, and a common community structure. The community structure is hierarchical, with the top level of the hierarchy comprising five industry communities: food industries, chemical industries, manufacturing industries, service industries, and extraction industries.

  2. Factors Behind Industrial Profit Growth

    2008-01-01

    This paper analyzes Chinese enterprise industrial profit distribution and profitability rise between 1998 and 2005. Looking at it from the perspective of drivers of total growth, this paper will provide an in-depth analysis of the origins and industry-level factors involved in this growth. It reaches the conclusion that structural change in profits was the main driving force for profit increases, to which heavy industry contributed greatly. Light and machine building industry profit rates improved due to increases in productivity levels, while energy and raw material industry profits increased due to increases in product prices. In addition, average wages grew slower than GDP, and wages among industries varied widely. In general however, this paper sets out to determine which enterprises gained from increases in industrial profitability, and how this gain came about.

    This paper presents a finite element thermal model for similar and dissimilar alloy friction stir spot welding (FSSW). The model is calibrated and validated using instrumented lap joints in Al-Al and Al-Fe automotive sheet alloys. The model successfully predicts the thermal histories for a range of process conditions. The resulting temperature histories are used to predict the growth of intermetallic phases at the interface in Al-Fe welds. Temperature predictions were used to study the evolution of hardness of a precipitation-hardened aluminum alloy during post-weld aging after FSSW.

  7. A Design Methodology For Industrial Vision Systems

    1988-11-01

    The cost of design, rather than that of target system hardware, represents the principal factor inhibiting the adoption of machine vision systems by manufacturing industry. To reduce design costs to a minimum, a number of software and hardware aids have been developed or are currently being built by the authors. These design aids are as follows: a. An expert system for giving advice about which image acquisition techniques (i.e. lighting/viewing techniques) might be appropriate in a given situation. b. A program to assist in the selection and setup of camera lenses. c. A rich repertoire of image processing procedures, integrated with the Al language Prolog. This combination (called ProVision) provides a facility for experimenting with intelligent image processing techniques and is intended to allow rapid prototyping of algorithms and/or heuristics. d. Fast image processing hardware, capable of implementing commands in the ProVision language. The speed of operation of this equipment is sufficiently high for it to be used, without modification, in many industrial applications. Where this is not possible, even higher execution speed may be achieved by adding extra modules to the processing hardware. In this way, it is possible to trade speed against the cost of the target system hardware. New and faster implementations of a given algorithm/heuristic can usually be achieved with the expenditure of only a small effort. Throughout this article, the emphasis is on designing an industrial vision system in a smooth and effortless manner. In order to illustrate our main thesis that the design of industrial vision systems can be made very much easier through the use of suitable utilities, the article concludes with a discussion of a case study: the dissection of tiny plants using a visually controlled robot.

On average, economic growth has been significantly stronger in developing economies than in high-income countries, although progress cannot be observed everywhere. The financial turmoil in ASIA, the tragic events in Sudan and the conflicts in the Balkans are reminders that there is still a long way to go before the world economy is on a path of peaceful, sustainable growth. The international energy scene is characterized by increased competition on two fronts: companies and host countries. Thus the world upstream market is behaving more and more like a genuine market where the forces of supply and demand play an increasing role. 5 refs.

    Full Text Available A new, cost-efficient and on-site-applicable thermal spraying process for depositing NiAl metallic overlay or bond-coat coatings for high temperature applications by synthesizing the desired intermetallic phases in-flight during oxy-acetylene flame spraying is presented. Base-metal powders were used for spraying and, by adjusting the spraying conditions, excellent NiAl-based coatings were achieved on various substrates, including mild steel, stainless steel and aluminium alloys. Expensive, pre-alloyed or agglomerated powders are avoided and the method is very promising for in-situ work and repairs. We call the new method “Combustion-Assisted Flame Spraying” (CAFSY and its viability has been demonstrated at a pre-industrial level for coating metallic substrates. The NiAl-based coatings produced by CAFSY exhibit very high integrity with good adhesion, very low porosity, high surface hardness and high erosion resistance at a substantially lower cost than equivalent coatings using pre-prepared alloy powders.

    2011-01-01

    The most recent developments in the area of deep DNA sequencing and downstream quantitative and functional analysis are rapidly adding a new dimension to understanding biochemical pathways and metabolic interdependencies. These increasing insights pave the way to designing new strategies that address public needs, including environmental applications and therapeutic inventions, or novel cell factories for sustainable and reconcilable energy or chemicals sources. Adding yet another level is building upon nonnaturally occurring networks and pathways. Recent developments in synthetic biology have created economic and reliable options for designing and synthesizing genes, operons, and eventually complete genomes. Meanwhile, high-throughput design and synthesis of extremely comprehensive DNA sequences have evolved into an enabling technology already indispensable in various life science sectors today. Here, we describe the industrial perspective of modern gene synthesis and its relationship with synthetic biology. Gene synthesis contributed significantly to the emergence of synthetic biology by not only providing the genetic material in high quality and quantity but also enabling its assembly, according to engineering design principles, in a standardized format. Synthetic biology on the other hand, added the need for assembling complex circuits and large complexes, thus fostering the development of appropriate methods and expanding the scope of applications. Synthetic biology has also stimulated interdisciplinary collaboration as well as integration of the broader public by addressing socioeconomic, philosophical, ethical, political, and legal opportunities and concerns. The demand-driven technological achievements of gene synthesis and the implemented processes are exemplified by an industrial setting of large-scale gene synthesis, describing production from order to delivery.

    Green industry has been identified as an important element in attaining greater sustainability. It calls for harmonizing robust economic growth with environment protection. Industries, particularly in developing and transitional nations such as Malaysia, are in need of a reform. Many experts and international organizations suggest the concept of industrial symbiosis. Mainly, there are successful cases of industrial symbiosis practices around the world. However, there are numerous cases of failure too. As industrial symbiosis is an emerging new approach, with a short history of two decades, a lot of researches are generally focused on narrow context and technical details. There is a lack of concerted efforts to look into the drivers and barriers of industrial symbiosis across different cases. This paper aims to examine the factors influencing the development of industrial symbiosis from various countries to supports such networks to evolve in Pasir Gudang. The findings show institution, law and regulation, finance, awareness and capacity building, technology, research and development, information, collaboration, market, geography proximity, environmental issues and industry structure affect the formation of industrial symbiosis.

    The crystal structure of new self-assembled InSb/AlAs and AlSb/AlAs quantum dots grown by molecularbeam epitaxy has been investigated by transmission electron microscopy. The theoretical calculations of the energy spectrum of the quantum dots have been supplemented by the experimental data on the steady-state and time-resolved photoluminescence spectroscopy. Deposition of 1.5 ML of InSb or AlSb on the AlAs surface carried out in the regime of atomic-layer epitaxy leads to the formation of pseudomorphically strained quantum dots composed of InAlSbAs and AlSbAs alloys, respectively. The quantum dots can have the type-I and type-II energy spectra depending on the composition of the alloy. The ground hole state in the quantum dot belongs to the heavy-hole band and the localization energy of holes is much higher than that of electrons. The ground electron state in the type-I quantum dots belongs to the indirect X XY valley of the conduction band of the alloy. The ground electron state in the type-II quantum dots belongs to the indirect X valley of the conduction band of the AlAs matrix.

    The IEA Policy Pathway publications provide details on how to implement specific recommendations drawn from the IEA 25 Energy Efficiency Policy Recommendations. This Policy Pathway, jointly produced by the International Energy Agency and the Institute for Industrial Productivity, develops the critical steps for policy makers implementing energy management programmes for industry. Optimising energy use in industry is essential to improve industrial competitiveness and achieve wider societal goals such as energy security, economic recovery and development, climate change mitigation and environmental protection. While there is significant potential to decrease energy consumption in this sector, opportunities to improve energy efficiency are still under-exploited. Energy management programmes have shown to be instrumental in addressing many of the barriers that inhibit wide-scale uptake of energy management in industry. The Policy Pathway builds on lessons learned from country experiences and provides actionable guidance on how to plan and design, implement, evaluate and monitor energy management programmes for industry.

    The biotech industry now accounts for a substantial and growing proportion of total R&D spending on new medicines. However, compared with the pharmaceutical industry, the biotech industry is financially fragile. This article illustrates the financial fragility of the biotech and pharmaceutical industries in the US and the implications of this fragility for the effects that government regulation could have on biotech firms. Graphical analysis and statistical tests were used to show how the biotech industry differs from the pharmaceutical industry. The two industries' characteristics were measured and compared, along with various measures of firms' financial risk and sensitivity to government regulation. Data from firms' financial statements provided accounting-based measures and firms' stock returns applied to a multifactor asset pricing model provided financial market measures. The biotech industry was by far the most research-intensive industry in the US, averaging 38% R&D intensity (ratio of R&D spending to total firm assets) over the past 25 years, compared with an average of 25% for the pharmaceutical industry and 3% for all other industries. Biotech firms exhibited lower and more volatile profits and higher market-related and size-related risk, and they suffered more negative stock returns in response to threatened government price regulation. Biotech firms' financial risks increase their costs of capital and make them more sensitive to government regulations that affect their financial prospects. As biotech products grow to represent a larger share of new medicines, general stock market conditions and government regulations could have a greater impact on the level of innovation of new medicines.

  17. Nucleation and Growth of Cu-Al Intermetallics in Al-Modified Sn-Cu and Sn-Ag-Cu Lead-Free Solder Alloys

    Lead-free solder alloys Sn-Cu (SC) and Sn-Ag-Cu (SAC) are widely used by the microelectronics industry, but enhanced control of the microstructure is needed to improve solder performance. For such control, nucleation and stability of Cu-Al intermetallic compound (IMC) solidification catalysts were investigated by variation of the Cu (0.7-3.0 wt.%) and Al (0.0-0.4 wt.%) content of SC + Al and SAC + Al alloys, and of SAC + Al ball-grid array (BGA) solder joints. All of the Al-modified alloys produced Cu-Al IMC particles with different morphologies and phases (occasionally non-equilibrium phases). A trend of increasing Cu-Al IMC volume fraction with increasing Al content was established. Because of solidification of non-equilibrium phases in wire alloy structures, differential scanning calorimetry (DSC) experiments revealed delayed, non-equilibrium melting at high temperatures related to quenched-in Cu-Al phases; a final liquidus of 960-1200°C was recorded. During cooling from 1200°C, the DSC samples had the solidification behavior expected from thermodynamic equilibrium calculations. Solidification of the ternary alloys commenced with formation of ternary β and Cu-Al δ phases at 450-550°C; this was followed by β-Sn, and, finally, Cu6Sn5 and Cu-Al γ1. Because of the presence of the retained, high-temperature phases in the alloys, particle size and volume fraction of the room temperature Cu-Al IMC phases were observed to increase when the alloy casting temperature was reduced from 1200°C to 800°C, even though both temperatures are above the calculated liquidus temperature of the alloys. Preliminary electron backscatter diffraction results seemed to show Sn grain refinement in the SAC + Al BGA alloy.

  20. The electricity industry perspective

    Energy Technology Data Exchange (ETDEWEB)

    Orchison, K. [Electricity Supply Association of Australia Ltd., Sydney, NSW (Australia)

    1996-12-31

    A revolution has been sweeping through the electricity supply business in Australia in the past decade and especially in the past five years. Electricity suppliers were early adherents to the pursuit of economic reform, beginning a drive towards greater efficiency in the mid-1980s and accelerating the process as government, pushed in turn by industry and commerce, took up pursuit of competitive energy markets, including radical restructuring of the State-owned utility organizations. The aim of this paper is to provide an overview of the electricity supply business. It include an outline of the major challenges confronting the electricity supply business in Australia, particularly as a result of the introduction of competitive markets in electricity and natural gas. Deregulation will see the providers of electricity and gas reposition themselves as organizations able to supply the total energy needs of customers. A de-regulated electricity market also offers cogeneration plants new opportunities to sell surplus electricity to generators, distribution businesses or directly to customers. The major frontiers facing the electricity supply business in Australia is seen to be that of productively channelling change. How this is handled has substantial implications for those who purchase electricity, suppliers of fuel to electricity generators or rivals in the marketplace. (author).
