    Márcia Lise Lunardi

    2011-12-01

    Full Text Available Este trabalho pretende focalizar a constituição e a produção da anormalidade dos sujeitos surdos nos discursos da Educação Especial. Nesse sentido, procura problematizar algumas regularidades discursivas que aparecem em materiais técnicos-científicos produzidos pelo MEC/SEESP, ou seja, discursos que funcionam como um duplo entre inclusão/exclusão, fronteira que narra e localiza o lugar dos sujeitos surdos. A partir dos estudos do filósofo Michael Foucault busca entender o binômio inclusão/exclusão, como uma estratégia de normalidade, como um mecanismo de poder que, ao tratar de incluir, acaba por normalizar. Por meio do conjunto dos materiais analisados (produção técnica-científica elaborada e divulgada pelo Ministério de Educação em parceria com a Secretaria de Educação Especial para a área da surdez, procura mostrar como a inclusão/exclusão funciona como um duplo e como as políticas de inclusão, dirigidas aos sujeitos surdos, operam como gerenciadoras do risco social.Palavras-chave: Inclusão/Exclusão. Normalização. Surdez. Risco Social.

  2. Algunos puntos básicos en torno al darwinismo y el antidarwinismo, para tratar en un curriculo de ciencias naturales

    2009-09-01

    Full Text Available A partir de su reflexión sobre la importancia de reconocer las visiones de mundo que los estudiantes presentan ante el origen de la vida, el autor comienza proponiendo algunos puntos que considera importantes en una clase de ciencias, para desarrollar el darwinismo en su interior, no como la imposición científica del maestro, sino como una visión más que puede convivir y respetar a las demás. Estos puntos abordan al darwinismo en su etapa más temprana posible, pasan por sus modificaciones actuales, continúan con las objeciones hechas a la teoría alrededor de 1900, luego tratan la relación del darwinismo con la continua creación evolución y, por último, presentan una correspondencia entre darwinismo y sociología del conocimiento científico con el propósito de mejorar la contextualización de las ideas científicas alrededor del origen y desarrollo de la vida.

    Full Text Available Aunque el objetivo óptimo del tratamiento de la Hepatitis B, sería la erradicación del virus, con las terapias con que contamos, en la actualidad, esto se consigue en un porcentaje mínimo de los pacientes. Por lo tanto, según el conocimiento actual, queda claro que el tratamiento que genera y logra mantener una supresión de larga duración del HBV DNA en niveles indetectables, reduce la incidencia de enfermedad hepática avanzada y hepatocarcinoma y este debería ser el objetivo que se plantee al tratar a los pacientes. Para la decisión de qué pacientes tratar debe considerarse su perfil clínico, perfil serológico, bioquímico y valores de carga viral. En algunas ocasiones, el clínico completará el estudio con una biopsia hepática. Hay tres grupos de pacientes por considerar cuándo se evalúa el paciente para darle tratamiento y todos tienen criterios distintos que guiarán la decisión del médico tratante, a saber: pacientes con hepatitis crónica HbeAg positivo, pacientes con hepatitis crónica HbeAg negativo, pacientes con enfermedad hepática avanzada.

  9. Benefits and costs of alcoholic relationships and recovery through Al-Anon.

    Science.gov (United States)

    Young, Lance Brendan; Timko, Christine

    2015-01-01

    Codependence is an ambiguous and disputed term often used to characterize both those who maintain relationships with alcoholics and those who seek help through resources such as Al-Anon Family Groups. The purpose of this article is to better understand non-pathological reasons for maintaining alcoholic relationships and for help-seeking by detailing the costs and benefits of those choices. The costs and benefits both of remaining in an alcoholic relationship and of seeking help in Al-Anon were identified through a review of available research on alcoholic family systems, Al-Anon, and other mutual-support groups. Alcoholic relationships may benefit concerned others by preserving self-identity, social identity, values, security, stability, and hope. Costs of alcoholic relationships include physical symptoms, injury, mental problems, financial difficulty, legal troubles, and relational distress. Al-Anon is perceived beneficial for six primary reasons: Al-Anon philosophy, format, social support, accessibility, effectiveness, and potential to change the drinker's behavior. Possible costs of Al-Anon include marginalization of the concerned other, blame, codependent pathology, sexist stereotyping, substitute dependency, and perpetuating victimization. Conclusions/Importance: The identified costs and benefits of alcoholic relationships and help-seeking in Al-Anon can help to model decision-making processes using existing behavioral health frameworks without defaulting to the stigmatized and ambiguous codependence terminology.

  14. Low Cost Al-Si Casting Alloy As In-Situ Composite for High Temperature Applications

    Science.gov (United States)

    Lee, Jonathan A.

    2000-01-01

    A new aluminum-silicon (Al-Si) alloy has been successfully developed at NASA- Marshall Space Flight Center (MSFC) that has significant improvement in tensile and fatigue strength at elevated temperatures (500 F-700 F). The alloy offers a number of benefits such as light weight, high hardness, low thermal expansion and high surface wear resistance. In hypereutectic form, this alloy is considered as an in-situ Al-Si composite with tensile strength of about 90% higher than the auto industry 390 alloy at 600 F. This composite is very economically produced by using either conventional permanent steel molds or die casting. The projected material cost is less than $0.90 per pound, and automotive components such as pistons can be cast for high production rate using conventional casting techniques with a low and fully accounted cost. Key Words: Metal matrix composites, In-situ composite, aluminum-silicon alloy, hypereutectic alloy, permanent mold casting, die casting.

  15. Balancing low cost with reliable operation in the rotordynamic design of the ALS Liquid Hydrogen Fuel Turbopump

    Science.gov (United States)

    Greenhill, L. M.

    1990-01-01

    The Air Force/NASA Advanced Launch System (ALS) Liquid Hydrogen Fuel Turbopump (FTP) has primary design goals of low cost and high reliability, with performance and weight having less importance. This approach is atypical compared with other rocket engine turbopump design efforts, such as on the Space Shuttle Main Engine (SSME), which emphasized high performance and low weight. Similar to the SSME turbopumps, the ALS FTP operates supercritically, which implies that stability and bearing loads strongly influence the design. In addition, the use of low cost/high reliability features in the ALS FTP such as hydrostatic bearings, relaxed seal clearances, and unshrouded turbine blades also have a negative influence on rotordynamics. This paper discusses the analysis conducted to achieve a balance between low cost and acceptable rotordynamic behavior, to ensure that the ALS FTP will operate reliably without subsynchronous instabilities or excessive bearing loads.

  16. Un acercamiento al coste de la dependencia en españa

    Segovia González, Mª Manuela

    2006-01-01

    Full Text Available En las últimas décadas, las sociedades industrializadas se han encontrado con un problema demográfico con fuertes consecuencias sociales y económicas, nos referimos al fenómeno de la dependencia de las personas mayores. España ha aprobado recientemente la “Ley de Promoción de la Autonomía Personal y Atención a Personas en Situación de Dependencia”, esta ley de carácter universal y público pretende garantizar la atención y cuidados de las personas que la padecen implicando a todas las Administraciones en el ejercicio de sus competencias. Es una cobertura de gran envergadura no sólo por el número de personas que se cubrirán sino por el gran coste económico y de recursos que serán precisos. En el trabajo que presentamos en este Congreso, que forma parte de un estudio amplio sobre la dependencia en España, realizaremos un acercamiento a la cuantificación económica del coste al que se deberán enfrentar a nivel nacional, y en concreto las Comunidades Autónomas de Andalucía y Extremadura. Para ello, utilizando técnicas actuariales estudiaremos la tasa de prevalencia de la dependencia mediante el análisis de la Encuesta sobre Discapacidades, Deficiencias y Estados de Salud de 1999.

Todos o casi todos los sistemas tienden a abarcar dos puntos principales; la mayor producción en cantidad y calidad aceptable sin debilitamiento de la planta y la búsqueda de economía en su ejecución. Sus principios, normas, implementos, épocas y demás factores varían con la planta y los puntos de vista del preconizador de los diferentes sistemas, pero todos están acordes en cuanto a la necesidad de proteger los cortes hechos durante las prácticas.

    Nussbaum, Martha C.

    2002-12-01

    Full Text Available The new possibilities opened up by scientific research, particularly in the area of genetic, raise hitherto unknown moral perplexities and, at the same time, do force us to rethink questions and redefine concepts which use to work adequately up to now. So, for example, regarding to theories of justice: we are used to having a relatively broad agreement on the concept of person, and the discussion was usually focused on the kind of goods which must be distributed to a given group of people. But the possibility of transforming people by changing their talents, and in this way, transforming some features of the population according to certain current criteria, opens up an important discussion insofar those transformations could be considered resources and, if so, been redistributed themselves. However, the fact that some sort of alterations could or, even more, should be made in order to achieve the good for future children embodies the risk consisting in the impoverishment and homogenization of the society, or the obliteration of valuable forms of life and culture. Since this incipient possibility arises paradoxes and disturbing threats, the rigorous reflection represents a basic indispensable critical tool.

    Las nuevas posibilidades abiertas por la investigación científica, especialmente en el campo de la genética, por un lado generan interrogantes morales hasta ahora desconocidos y, por otro, nos obligan a reformular de una manera totalmente nueva cuestiones y conceptos que hasta ahora funcionaban de forma adecuada. Así ocurre, por ejemplo, con las teorías de la justicia: estamos acostumbrados a que exista un acuerdo relativamente amplio en torno al concepto de persona, y la discusión se suele centrar en el tipo de bienes que habrían de distribuirse entre un conjunto dado de individuos. Pero la posibilidad de transformar los talentos personales y, así, modificar algunos rasgos de nuestra población de acuerdo con criterios actuales

  20. Improved High-Energy Response of AlGaAs/GaAs Solar Cells Using a Low-Cost Technology

    Noorzad, Camron D.; Zhao, Xin; Harotoonian, Vache; Woodall, Jerry M.

    2016-12-01

    We report on an AlGaAs/GaAs solar cell with a significantly increased high-energy response that was produced via a modified liquid phase epitaxy (LPE) technique. This technique uses a one-step process in which the solid-liquid equilibrium Al-Ga-As:Zn melt in contact with an n-type vendor GaAs substrate simultaneously getters impurities in the substrate that shorten minority carrier lifetimes, diffuses Zn into the substrate to create a p- n junction, and forms a thin p-AlGaAs window layer that enables more high-energy light to be efficiently absorbed. Unlike conventional LPE, this process is performed isothermally. In our "double Al" method, the ratio of Al in the melt ("Al melt ratio") that was used in our process was two times more than what was previously reported in the record 1977 International Business Machines (IBM) solar cell. Photoluminescence (PL) results showed our double Al sample yielded a response to 405 nm light ("blue light"), which was more than twice as intense as the response from our replicated IBM cell. The original 1977 cell had a low-intensity spectral response to photon wavelengths under 443 nm (Woodall and Hovel in Sol Energy Mater Sol Cells 29:176, 1990). Secondary ion mass spectrometry results confirmed the increased blue light response was due to a large reduction in AlGaAs window layer thickness. These results proved increasing the Al melt ratio broadens the spectrum of light that can be transmitted through the window layer into the active GaAs region for absorption, increasing the overall solar cell efficiency. Our enhanced double Al method can pave the way for large-scale manufacturing of low-cost, high-efficiency solar cells.

    Hales, Stephen J.; Wagner, John A.

    1991-01-01

    Superplastic forming of advanced aluminum alloys is being evaluated as an approach for fabricating low-cost, light-weight, cryogenic propellant tanks. Built-up structure concepts (with inherent reduced scrap rate) are under investigation to offset the additional raw material expenses incurred by using aluminum lithium alloys. This approach to fabrication offers the potential for significant improvements in both structural efficiency and overall manufacturing costs. Superplasticity is the ability of specially processed material to sustain very large forming strains without failure at elevated temperatures under controlled deformation conditions. It was demonstrated that superplastic forming technology can be used to fabricate complex structural components in a single operation and increase structural efficiency by as much as 60 percent compared to conventional configurations in skin-stiffened structures. Details involved in the application of this technology to commercial grade superplastic aluminum lithium material are presented. Included are identification of optimum forming parameters, development of forming procedures, and assessment of final part quality in terms of cavitation volume and thickness variation.

    2002-01-01

    Full Text Available La aplicación de la teoría de juegos a las ciencias sociales ha supuesto un importante avance a todos los niveles. La teoría de juegos estudia situaciones en las que interactúan dos o más jugadores racionales que se plantean un conflicto de intereses. Un juego cooperativo es aquel en que los jugadores pueden tomar acuerdos vinculantes, que estos juegos sean además de utilidad transferible implica que las ventajas que obtengan las coaliciones derivadas de dicha cooperación (mayores beneficios, ahorro de costes, incremento de la producción, etc. podrán redistribuirse entre sus miembros de cualquier manera. Este trabajo estudia la aplicación de la teoría de juegos cooperativos con utilidad transferible a problemas de reparto de costes asociados a la creación de canales de distribución de un bien suministrado por un único proveedor o fuente. Se propone como concepto de solución el concepto de núcleo y como regla para obtener asignaciones del núcleo la regla de reparto de Bird. Ponemos de manifiesto cómo en el caso vectorial el concepto de núcleo ha de ser revisado y demostramos que la regla de Bird proporciona asignaciones del núcleo de dominancia.

  4. Understanding and development of cost-effective industrial aluminum back surface field (Al-BSF) silicon solar cells

    Science.gov (United States)

    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

    A disposable cable-shaped flexible battery is presented using a simple, low cost manufacturing process. The working principle of an aluminum-air galvanic cell is used for the cable-shaped battery to power portable and point-of-care medical devices. The battery is catalyzed with a carbon nanotube (CNT)-paper matrix. A scalable manufacturing process using a lathe is developed to wrap a paper layer and a CNT-paper matrix on an aluminum wire. The matrix is then wrapped with a silver-plated copper wire to form the battery cell. The battery is activated through absorption of electrolytes including phosphate-buffered saline, NaOH, urine, saliva, and blood into the CNT-paper matrix. The maximum electric power using a 10 mm-long battery cell is over 1.5 mW. As a demonstration, an LED is powered using two groups of four batteries in parallel connected in series. Considering the material composition and the cable-shaped configuration, the battery is fully disposable, flexible, and potentially compatible with portable biosensors through activation by either reagents or biological fluids.

    The ALS project plan goals are reducing cost, improving performance, and achieving flight readiness. ALS selects projects to advance the mission readiness of low cost, high performance technologies. The role of metrics is to help select good projects and report progress. The Equivalent Mass (EM) of a system is the sum of the estimated mass of the hardware, of its required materials and spares, and of the pressurized volume, power supply, and cooling system needed to support the hardware in space. EM is the total payload launch mass needed to provide and support a system. EM is directly proportional to the launch cost.

  9. An Alternative Low-Cost Process for Deposition of MCrAlY Bond Coats for Advanced Syngas/Hydrogen Turbine Applications

    Energy Technology Data Exchange (ETDEWEB)

    Zhang, Ying [Tennessee Technological Univ., Cookeville, TN (United States)

    2015-09-11

    The objective of this project was to develop and optimize MCrAlY bond coats for syngas/hydrogen turbine applications using a low-cost electrolytic codeposition process. Prealloyed CrAlY-based powders were codeposited into a metal matrix of Ni, Co or Ni-Co during the electroplating process, and a subsequent post-deposition heat treatment converted it to the MCrAlY coating. Our research efforts focused on: (1) investigation of the effects of electro-codeposition configuration and parameters on the CrAlY particle incorporation in the NiCo-CrAlY composite coatings; (2) development of the post-deposition heat treating procedure; (3) characterization of coating properties and evaluation of coating oxidation performance; (4) exploration of a sulfurfree electroplating solution; (5) cost analysis of the present electrolytic codeposition process. Different electro-codeposition configurations were investigated, and the rotating barrel system demonstrated the capability of depositing NiCo-CrAlY composite coatings uniformly on the entire specimen surface, with the CrAlY particle incorporation in the range 37-42 vol.%. Post-deposition heat treatment at 1000-1200 °C promoted interdiffusion between the CrAlY particles and the Ni-Co metal matrix, resulting in β/γ’/γ or β/γ’ phases in the heat-treated coatings. The results also indicate that the post-deposition heat treatment should be conducted at temperatures ≤1100 °C to minimize Cr evaporation and outward diffusion of Ti. The electro-codeposited NiCrAlY coatings in general showed lower hardness and surface roughness than thermal spray MCrAlY coatings. Coating oxidation performance was evaluated at 1000-1100 °C in dry and wet air environments. The initial electro-codeposited NiCoCrAlY coatings containing relatively high sulfur did not show good oxidation resistance. After modifications of the coating process, the cleaner NiCoCrAlY coating exhibited good oxidation performance at 1000 °C during the 2,000 1-h cyclic

    Full Text Available This article analyzes the pillars that supported the therapeutic practice in Yucatán to treat cholera patients during the outbreaks preceding the discovery of its bacterial etiology, one in 1833 and another in 1853. Due partly to a significant evolution in scientific and medical ideas, and the dissemination of the principles of positivism, a profound process of transformation was experienced, which brought, among other things, new perceptions of the disease as well as schemes different from the colonials to deal with emergencies and ensure public health. However, given the lack of consensus about the origin of cholera and its means of propagation, the government promoted different therapeutic techniques practiced in Europe or the United States, alongside local knowledge on the medicinal use of herbs, while also reviving old ideas on the impact of individual moral behavior in the tendency to contract the disease and eventually die.Este artículo analiza los pilares que sostuvieron la práctica terapéutica en Yucatán para tratar a los enfermos de cólera durante los brotes registrados antes del descubrimiento de su etiología bacteriana, uno en 1833 y otro en 1853. Debido en parte a una importante evolución del pensamiento médico-científico y a la divulgación de los principios del positivismo, en esta época se vivió un profundo proceso de transformación que significó, entre otras cosas, nuevas percepciones sobre la enfermedad y esquemas distintos a los coloniales para afrontar las emergencias y procurar la salud pública. Sin embargo, ante la falta de consensos en cuanto al origen del cólera y sus medios de propagación, el gobierno estatal promovió la difusión de diferentes técnicas terapéuticas empleadas en Europa o Estados Unidos, que se sumaron al conocimiento local respecto al empleo medicinal de la herbolaria, retomando también antiguas ideas sobre la incidencia de las conductas morales individuales en la propensión al

    InN/ZnO:Al heterostructures deposited at low temperature on different substrates by radio-frequency sputtering were studied. Using ZnO:Al as buffer layer, an improvement in the InN structural properties was achieved. Evaluating ZnO:Al as contact on InN, an Ohmic behaviour for the as-deposited layer on InN was achieved. A specific contact resistance of 2 {omega} cm{sup 2} was measured without any post-deposition treatment. These properties could result very promising for optoelectronic device applications.

    Development efforts have been undertaken to improve the processing and structural efficiencies of advanced cold-formable beta Ti alloys, using the standard, hot-formed and rivetted construction of Ti-6Al-4V sheet structures as a basis for comparison. Ti-15V-3Cr-3Al-3Sn (Ti-15-3) beta alloy is formable, brazable and weldable in the solution-treated condition, and after aging displays mechanical properties suitable for postulated service in the -65 to 600 F temperature range. A novel methodology using cold-formed Ti-15-3 stringers and Ti-6Al-4V face sheets that are joined by means of an out-of-furnace isothermal brazing process, followed by low temperature aging, can reduce production costs by as much as 28 per cent. Structural efficiency has been demonstrated in room and elevated temperature crippling tests of small skin-stringer assemblies.

    Full Text Available OBJECTIVE: To compare the effectiveness between the see-and-treat (S&T approach and the conventional one (with prior biopsy for squamous intraepithelial lesions of uterine cervix. METHODS: A cross-sectional study was conducted with 900 nonpregnant women with cytology suggestive of high grade squamous intraepithelial lesions in the city of Rio de Janeiro, Southeastern Brazil, between 1998 and 2004. The S&T approach consists of a large loop excision of the transformation zone procedure and is recommended when cytology is suggestive of high grade squamous intraepithelial lesion, satisfactory colposcopy with abnormalities compatible with the suspected cytological results, and the lesion is limited to the ectocervix or extends up to one centimeter of the endocervical canal. A subgroup of 336 patients whose colposcopy was considered satisfactory was analyzed, and they were divided into two groups for comparison: patients treated without prior biopsy (n = 288 and patients treated after a biopsy showing high grade squamous intraepithelial lesions (n = 48. Patients who were not treated or only treated more than a year later after recruitment at the colposcopy unit were considered dropouts. RESULTS: Of patients recruited during the study period, 71 were not treated or were only treated for at least a year. The overall dropout rate was 7.9% (95% CI: 6.1;9.7. Mean time elapsed between patient recruitment and treatment was 17.5 days in the S&T group and 102.5 days in the prior biopsy group. Dropout rates were 1.4% (95% CI: 0.04;2.7 and 5.% (95% CI: 0;12.3, respectively (p=0.07. The proportion of overtreated cases (negative histology in the S&T group was 2.0% (95% CI: 0.4;3.6. CONCLUSIONS: The difference in the mean time elapsed between patient recruitment and treatment indicates that S&T is a time-saving approach The proportion of negative cases from using the S&T approach can be regarded as low.OBJETIVO: Comparar la efectividad del método "ver-y-tratar" (V

    Silicon/carbon (Si/C) composite shows great potential to replace graphite as lithium-ion battery (LIB) anode owing to its high theoretical capacity. Exploring low-cost scalable approach for synthesizing Si/C composites with excellent electrochemical performance is critical for practical application of Si/C anodes. In this study, we rationally applied a scalable in situ approach to produce Si-carbon nanotube (Si-CNT) composite via acid etching of commercial inexpensive micro-sized Al-Si alloy powder and CNT mixture. In the Si-CNT composite, ∼10 nm Si particles were uniformly deposited on the CNT surface. After combining with graphene sheets, a flexible self-standing Si-CNT/graphene paper was fabricated with three-dimensional (3D) sandwich-like structure. The in situ presence of CNT during acid-etching process shows remarkable two advantages: providing deposition sites for Si atoms to restrain agglomeration of Si nanoparticles after Al removal from Al-Si alloy powder, increasing the cross-layer conductivity of the paper anode to provide excellent conductive contact sites for each Si nanoparticles. When used as binder-free anode for LIBs without any further treatment, in situ addition of CNT especially plays important role to improve the initial electrochemical activity of Si nanoparticles synthesized from low-cost Al-Si alloy powder, thus resulting in about twice higher capacity than Si/G paper anode. The self-standing Si-CNT/graphene paper anode exhibited a high specific capacity of 1100 mAh g-1 even after 100 cycles at 200 mA g-1 current density with a Coulombic efficiency of >99%. It also showed remarkable rate capability improvement compared to Si/G paper without CNT. The present work demonstrates a low-cost scalable in situ approach from commercial micro-sized Al-Si alloy powder for Si-based composites with specific nanostructure. The Si-CNT/graphene paper is a promising anode candidate with high capacity and cycling stability for LIBs, especially for the

    Full Text Available Desde la perspectiva social los conceptos de utilidad terapéutica y grado de innovación de los nuevos medicamentos deben ser referidos al valor social añadido por los mismos en relación a las alternativas de tratamiento disponibles y los costes añadidos que comporten, esto es, a su relación coste-efectividad incremental. Los elementos analíticos que destacan en esta aproximación son: 1 las dimensiones del valor social del medicamento, que van más allá de las medidas de resultado convencionales para incorporar también medidas de calidad de vida relacionada con la salud, comodidad de los pacientes y sus familias, consumo de recursos sanitarios evitado y pérdidas productivas evitadas; 2 el carácter relativo o incremental de este valor, que debe cuantificarse frente a las alternativas preexistentes, no frente a placebo, y en condiciones de uso real; y 3 el gasto incremental que conlleve la administración del nuevo medicamento. El enfoque de la relación coste-efectividad incremental es el adecuado para las decisiones de cobertura de un determinado tratamiento por las aseguradoras públicas, del precio que se está dispuesto a pagar por él y de las situaciones clínicas y grupos de pacientes en los que se recomienda. El análisis coste-efectividad incremental y el establecimiento de un umbral indicativo del coste máximo que se está dispuesto a pagar por "año de vida ajustada por calidad" ganado son los elementos esenciales de esta aproximación, que no exige fijar el precio de los nuevos medicamentos en el umbral de la disponibilidad a pagar.

    Full Text Available Introducción: En Chile, el principal problema nutricional de la población infantil, lo constituye la obesidad. El alarmante incremento de la obesidad infantil, ha generado la imperiosa necesidad de desarrollar programas de prevención y tratamiento, pero los resultados han sido poco alentadores ya que no han logrado el impacto esperado en el estado nutricional de la población objetivo. Para lo cual es necesario utilizar otras estrategias, como la incorporación del ejercicio físico de fuerza muscular. Objetivo: Determinar el impacto de una intervención integral (ejercicio físico, educación alimentaria y apoyo psicológico en la composición corporal de escolares obesos al finalizar la intervención y en la post-intervención. Métodos: La muestra fue de 61 niños obesos (IMC > p 95 de ambos sexos, entre 8 y 13 años, que participaron en una intervención integral para tratar la obesidad infantil a corto plazo (3 meses y mediano plazo (12 meses. Se evaluó la composición corporal por dilución isotópica, pletismografía, absorciometría radiográfica y el modelo de cuatro compartimentos de Fuller. Resultados: En ambos sexos se produjo un incremento significativo en el tiempo en MLG (kg por 4C, en GC (% por dilución isotópica en niños se redujo en la post-intervención, mientras en las niñas disminuyó significativamente en el tiempo y en MLG (kg por dilución isotópica aumentó significativamente en ambos sexos. En relación a la magnitud y dirección de los cambios en el tiempo, sólo hubo diferencia significativa por sexo en MLG (% por dilución isotópica, el incremento fue significativamente mayor en niños, como producto de la intervención (p=0,000. Conclusiones: Una intervención que incluye ejercicio físico programado mejora la composición corporal, pero su efecto se revierte a mediano plazo si el entrenamiento cesa. Lo anterior, reafirma la necesidad de la sostenibilidad de las intervenciones en el tiempo.

    Full Text Available Estimation of the burden of disease attributable to smoking has now become standard in documenting the impact of the tobacco epidemic and in motivating tobacco control. This paper addresses the methods used to estimate the attributable burden of mortality and the related estimation of morbidity and economic costs. Estimates of attributable mortality and morbidity for the Americas range widely, reflecting the maturity of the tobacco epidemic. The estimates are highest for the United States, and lower for Mexico and other countries of the Americas.La medida del impacto de la epidemia de tabaquismo y la promoción del control del tabaco ha sido el estándar para estimar la carga total de enfermedades atribuible al consumo de tabaco. Este artículo estudia los métodos usados para estimar la mortalidad atribuible al consumo de tabaco, así como su morbilidad y los costos económicos. La mortalidad y morbilidad atribuible para la población de los Estados Unidos varía ampliamente, lo que refleja la madurez de la epidemia de tabaquismo. Las estimaciones para los Estados Unidos son altas, y más bajas para México y otros países de América.

    The high V/III ratio required for the Metalorganic Chemical Vapour Deposition (MOCVD) growth of AlN using the precursors trimethylaluminium and ammonia have contributed to the excessive costs of producing ultra violet light emitting diodes (UVLEDs) which can be used in water purification. This paper introduces a novel growth technique, vectored-flow epitaxy (VFE), which maintains the separation between gaseous reagents within the growth chamber. In addition, the VFE technique, which employs atmospheric pressure growth, also pre cracks the ammonia prior to injection and thereby significantly reduces the high V/III ratio required for the growth of this material. The pre cracked ammonia also removes the need for high growth temperatures, which is known to be necessary for its thermal decomposition. With this technique, 2 {mu}m/h growth is possible at a V/III ratio of 50. These advances will contribute to the development of a cost-effective solution to the treatment of drinking water in a rural environment. (copyright 2008 WILEY-VCH Verlag GmbH and Co.

    The energy consumption of the Metropolitan Zone of the Valley of Mexico (ZMVM) is presented, considering the different economic sectors and the different types of fuels used by them. The form in which this demand will impact the air quality largely depends on the energy balance. Also an inventory of the emissions in 1989 is given. It is possible to emphasize that the power balance maintains a close association with the emissions inventory, which reflects the dependency of the emissions with respect to the energy use. Finally an analysis is made of the considered environmental costs for Mexico.

    2016-06-01

    Full Text Available The MgAl2O4 nanocrystalline powder was synthesized using naturally available egg white and inexpensive metal nitrate salts. During this process, the freshly extracted egg white was mixed with metal nitrate salt and subsequently heated at 350 °C in a pit furnace. The entire dehydration of the aqueous solution thus facilitates the low-density fluffy mass. From TGDTG results, it was observed that maximum decomposition of the precursors occurred below 600 °C. Therefore, the calcination temperature of as-synthesized powder was set at 600 °C. The MgAl2O4 bulk ceramic foam was fabricated by dispersing different loading of MgAl2O4 nanoparticles in the egg white, and then coating on polyurethane sponge prior to drying and sintering at a higher temperature. The ceramic suspensions exhibit a typical shear thinning behavior, and its viscosity was found to be significantly influenced by MgAl2O4 powder content. An optimum loading of 40 wt% MgAl2O4 nanoparticles in the egg white was found to show maximum porosity up to 90%. The obtained ceramic foam has potential applications in catalysis, absorption and sensor.

    Full Text Available Abstract The Catalytic Wet Air Oxidation (CWAO of phenol using copper oxide catalysts supported by γ-Al2O3, TiO2, and pillared clay was evaluated to identify which of these catalysts was the most appropriate for this reaction. The CuO/PILC, CuO/γ-Al2O3 and CuO/TiO2 catalysts were the most successful at removing phenol and resulted in more than 96% conversion. Among these catalysts, CuO/γ-Al2O3 produced the largest amount of CO2, the lowest amount of intermediate products and the lowest amount of copper leaching. These results showed that the CuO/γ-Al2O3catalyst was the best for the end of the reaction. However, the methods used in this study did not allow us to identify the most appropriate reaction time (or catalyst. An alternative approach for this problem was to quantify the costs for each reaction time. Using this approach, the CuO/γ-Al2O3 catalyst was the most economically favorable catalyst when it was used during the first hour of the reaction.

RESULTADOS: Los costos totales anuales de atención médica nacional corresponden a 7 114 millones para el infarto agudo del miocardio, 3 424 millones para la enfermedad vascular cerebral, 1 469 millones para la enfermedad pulmonar obstructiva crónica y 102 millones para el cáncer pulmonar. El costo total anual para el IMSS por estas cuatro enfermedades asciende a 12 100 millones de pesos. Los costos atribuibles al consumo de tabaco corresponden a 7 100 millones de pesos, lo cual equivale a 4.3% del gasto de operación de la institución en el año 2004. CONCLUSIONES: Estos resultados confirman el elevado costo de la atención médica de las enfermedades atribuibles al consumo de tabaco en el IMSS y generan información de primera mano necesaria para impulsar las medidas de prevención en esa institución y reforzar las políticas de control del tabaquismo ya aplicadas en México.OBJECTIVE: To estimate the cost of medical care for the major diseases attributable to tobacco consumption at the IMSS.

    2016-11-01

    Carbon-coated Si-Cu3Si-Al2O3 nanocomposites have been synthesized via a facile mechanochemical reaction and employed as anode materials for lithium-ion batteries. Combined X-ray and microscopic studies show that the nanocomposites are composed of agglomerated nanostructured particles with uniform distribution of crystalline silicon, Cu3Si, and amorphous Al2O3. Electrochemical characterization reveals that the in situ incorporation of both the conductive Cu3Si and electrochemically stable Al2O3 phases results in a dramatic improvement of cyclability and rate capability, while the specific capacity decreases with increasing amount of Cu3Si. By controlling the Cu3Si content, the composite with a high tap density of ∼1.2 g cm-3 delivers a high reversible capacity of 841 mA h g-1, excellent cyclability, and good rate performance up to 3.2 A g-1 in half cells. Full-cell test coupled with a commercial spinel cathode also displays a high average operating voltage of >3.5 V, a relatively good capacity retention of ∼77.2% after 50 cycles with a high initial efficiency of ∼86.3%. The enhanced electrochemical performance is mainly attributed to the presence of the conductive Cu3Si buffer phase that mitigates structural degradation and offers high conductivity.

    The power economy is in a state of fundamental change. Since some time there have been increasing reports of unprofitable conventional power plants. This by no means only applies to old, inefficient plants but also to state-of-the-art gas and steam turbine plants. As a result many investors are switching their preferences toward wind power. Due to the reform of the German Renewable Energy Law, however, wind power, too, could develop towards becoming a not quite so safe haven in future. This makes it all the more important to make an accurate analysis of the costs, especially the maintenance costs, of wind power, and to do so for installations on land but more particularly for those at sea. For one thing is clear. The envisaged expansion rates can only be achieved if the projects planned prove profitable.

    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.

    ABSTRACT A recently published paper that assessed the comparative cost-effectiveness of the 2 pneumococcal conjugate vaccines (PCVs) in Malaysia and Hong Kong reported that the 13-valent PCV vaccine (PCV13) is a better choice compared to the 10-valent pneumococcal non-typeable Haemophilus influenzae protein D conjugate vaccine (PHiD-CV or PCV10) from both a payer and societal perspective as well as under various scenarios. However, the analysis relied on a large number of assumptions that were either erroneous or did not take into account the most recent body of evidence available. A rigorous evaluation of the underlying assumptions is necessary to present a fair and balanced analysis for decision-making. PMID:27459265

    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

  10. Minimizing Costs Can Be Costly

    Directory of Open Access Journals (Sweden)

    Rasmus Rasmussen

    2010-01-01

    Full Text Available A quite common practice, even in academic literature, is to simplify a decision problem and model it as a cost-minimizing problem. In fact, some type of models has been standardized to minimization problems, like Quadratic Assignment Problems (QAPs, where a maximization formulation would be treated as a “generalized” QAP and not solvable by many of the specially designed softwares for QAP. Ignoring revenues when modeling a decision problem works only if costs can be separated from the decisions influencing revenues. More often than we think this is not the case, and minimizing costs will not lead to maximized profit. This will be demonstrated using spreadsheets to solve a small example. The example is also used to demonstrate other pitfalls in network models: the inability to generally balance the problem or allocate costs in advance, and the tendency to anticipate a specific type of solution and thereby make constraints too limiting when formulating the problem.

    战略导向下的项目组合工期-成本优化是现代企业进行多项目管理所面临的重要问题之一,对企业实现资源效益最大化有着至关重要的促进作用。以战略导向下的项目组合工期-成本综合值最小化为研究对象,提出了优化组合项目中工序选择和执行次序的数学模型,在引入自适应权重法、调整信息素系数和混沌扰动变量的基础上,设计了求解该优化模型的改进蚁群算法。通过实例运算表明,改进后的蚁群算法,能够有效地提高算法全局搜索寻优能力和收敛速度,在求解战略导向下的项目组合工期-成本优化问题方面有较强的鲁棒性和实用价值。%The time-cost trade-off based on the strategic orientation is one of important questions for the multi-project management, which plays a key role in enterprise resources benefit maximization. In order to minimize the value of time-cost trade-off cost and time under the strategic orientation, this paper proposes a mathematical model for the optimi-zation of node selection and order execution in the project portfolio, an improved ant colony solution algorithm, which is on the basis of the adaptive weights, adjusting pheromone variable coefficients and chaotic perturbations has also been designed in this paper to solve the time-cost trade-off problem. The simulation results indicate that the improved algo-rithm can effectively improve global optimization ability, and much more robust and practical value in solving the time-cost optimization problem of project portfolio.

    Full Text Available In this article we discuss how the ideas of Cesare Lombroso (1835-1909 and his followers were incorporated into the intellectual debate in Brazil in the late 19th and early 20th centuries. By specifically analyzing the intellectual production of Brazilian legal scholars and jurists of the time - who drew on ideas from criminology to conceive Brazilian society and to propose legal and institutional reforms - we attempt to demonstrate how these ideas contributed to the elaboration of differentiated forms of legal and penal treatment for certain segments of the population.

    Stirk, Charles W.; Liu, Qin; Ball, Matthew V.

    1999-04-01

    This paper analyzes the manufacturing cost of photonic system using software that combines several methods for accurate cost accounting. Activity based costing assigns al capital equipment, material and labor costs directly to the product rather than to overheads. Cost of ownership models determine the cost of using machines under different financial and utilization scenarios. Libraries of standard machines, process steps, and process sequences facilitate rapid model building and modification. Using libraries for semiconductor and photonics fabrication, along with packaging and optomechanical assembly, we construct cost models for 2D VCSEL array communication modules. The result of the analysis is that the model cost is driven mainly by the epitaxial material cost, and laser yield limits VCSEL arrays to small scale integration.

Se incluyeron todos los estudios publicados en la literatura sobre el tema desde hace más de 25 años. Se obtuvo información de la población de estudio, la perspectiva de costeo, el tipo de análisis para la estimación de los costos de atención médica y la metodología de atribución de costos al consumo de tabaco. Además, se agregó un comentario de los hallazgos relevantes y de las limitaciones de cada uno de los estudios. Los costos anuales de atención médica atribuibles al consumo de tabaco oscilan entre 6 a 14% de los gastos personales en salud. Desde la primera publicación hasta la fecha se observa un progreso en la metodología de la estimación, no sólo desde la perspectiva epidemiológica -que afina la atribución de los costos al factor de riesgo- sino desde la económica -que amplía la estimación de los costos desde una perspectiva social. Se concluye que el consumo de tabaco deriva en altos costos de atención médica, y representa un alto costo social por las muertes prematuras que genera en la sociedad.The objective of this study was to compile information from published scientific literature about health care costs attributable to tobacco consumption and evaluate the different methodological strategies used in calculating

    Energy contracting is a contractual partnership between a contractor and a building owner. The contractor carries out investments and energy conservation measures in a building. He is refunded by the success of the energy conservation measures, i.e. on the basis of the reduced energy cost of the building. The building owner makes no investments, takes no risks and still gets part of the savings. Energy contracting refers to measures 'behind the meter', i.e. all measures that reduce the consumption of heat, electricity and, in some cases, also water. In contrast, plant contracting means that the contractor projects, constructs, finances, operates and maintains a supply system (e.g. heating boiler, cogeneration plant, wood chip fuelled heating system etc.) and is reimbursed on a contractual basis for the amount of electricity, heat, and cold supplied. [German] Energiespar-Contracting ist eine vertraglich vereinbarte Dienstleistung zwischen einem Unternehmen (Contractor oder auch Energiesparpartner) und einem Gebaeudeeigner (Auftraggeber). Der Contractor fuehrt in dem Gebaeude Investitionen und Massnahmen zur Energieeinsparung durch. Seine Aufwendungen laesst er sich durch den Erfolg der Einsparmassnahmen, also ueber die reduzierten Energiekosten des Gebaeudes, vergueten. Der Gebaeudeeigner muss nicht investieren, traegt kein Risiko und ist trotzdem an dem Erfolg der Einsparmassnahme beteiligt. Im Unterschied zum Anlagen-Contracting umfasst das Energiespar-Contracting Massnahmen, die hinter dem Zaehler ansetzen, also alle Massnahmen, die den Verbrauch von Waerme oder Strom reduzieren. Haeufig werden auch Massnahmen zur Wassereinsparung in die Konzepte einbezogen. Beim Anlagen-Contracting bietet ein Dienstleister in der Regel die Planung, Errichtung, Finanzierung, den Betrieb und die Wartung einer Versorgungsanlage (z.B. Heizkessel, Blockheizkraftwerk, Holzhackschnitzelanlage) an. Diese Dienstleistung laesst er sich ueber eine vertraglich festgelegte

    2012-07-01

    Full Text Available Firms are coping with a competitive scenario characterized by quick changes produced by internationalization, concentration, restructuring, technological innovation processes and financial market crisis. On the one hand market enlargement have increased the number and the segmentation of customers and have raised the number of competitors, on the other hand technological innovation has reduced product life cycle. So firms have to adjust their management models to this scenario, pursuing customer satisfaction and respecting cost constraints. In a context where price is a variable fixed by the market, firms have to switch from the cost measurement logic to the cost management one, adopting target costing methodology. The target costing process is a price driven, customer oriented profit planning and cost management system. It works, in a cross functional way, from the design stage throughout all the product life cycle and it involves the entire value chain. The process implementation needs a costing methodology consistent with the cost management logic. The aim of the paper is to focus on Activity Based Costing (ABC application to target costing process. So: -it analyzes target costing logic and phases, basing on a literary review, in order to highlight the costing needs related to this process; -it shows, through a numerical example, how to structure a flexible ABC model – characterized by the separation between variable, fixed in the short and fixed costs - that effectively supports target costing process in the cost measurement phase (drifting cost determination and in the target cost alignment; -it points out the effectiveness of the Activity Based Costing as a model of cost measurement applicable to the supplier choice and as a support for supply cost management which have an important role in target costing process. The activity based information allows a firm to optimize the supplier choice by following the method of minimizing the

    Full Text Available Al-Maqāmāt al-Luzūmiyya, a collection of 50 picaresque-like stories couched in rhymed prose by Abū l-Ṭāhir al-Saraqusṭī in al-Andalus in the VI/XIIth century, were considered by Western scholars, up until the eighties of XXth century, as highly rhetorical pieces with a negligible and irrelevant content. However, some contemporary scholars argued that they contain some degree of social and political criticism, as they constitute a fictional domain in which subversion and irony play a fundamental role. In this paper, we cast some light on the particular use of metrical patterns in Al-Maqāmāt al-Luzūmiyya, which should be considered another subversion field: a poetical rhythm that avoids the most usual Arabic metrical patterns, contributing to provide the maqāma a flavor of the countergenre.Al-Maqāmāt al-Luzūmiyya, la colección de 50 relatos de corte picaresco escritos en una exigente prosa rimada por Abū l-Ṭāhir al-Saraqusṭī en al-Andalus en el siglo VI/XII, han sido consideradas por los críticos occidentales como piezas de alta retórica y de virtuosismo lingüístico en las que el contenido es prácticamente irrelevante. Sin embargo, a partir de los años 80 del siglo pasado, algunos investigadores han tratado de incidir en el hecho de que esta obra contiene cierto grado de crítica social y política, puesto que constituye un espacio ficticio en el que la subversión y la ironía desempeñan un papel fundamental. En este trabajo vamos a tratar de arrojar luz sobre el uso particular de los esquemas métricos por parte de al-Saraqusṭī, tratando de mostrar que los metros constituyen otro más de los ámbitos de subversión tan caros al autor. De hecho, el uso de ritmos “invertidos” o contrarios a los más habituales de la poesía clásica contribuye a darle a la maqāma ese aire de anti género que la puebla.

    2005-10-01

    Full Text Available Quality has a cost and this fact cannot be denied. In the same time, it is true that non-quality is more expensive. Quality is considered asbeing expensive because no one tries to calculate non-quality costs. Out of the final cost of a product, non-quality stands for 20% up to 35%.According to this idea all the economic sectors contain error costs caused by the mistakes made during the production process. To have a realconsummation situation, it is necessary to know the cost quantum. The final quality cost is the result of the following costs: prevention costs,necessary to preclude errors; evaluation costs, as results of a final product evaluation, and failure costs, generated by the non – attainment ofproduct’s purpose. The gross of these costs stand for the total quality costs. Nowadays, the problem inheres in how much this quality cost representsout of the final cost.

    2014-05-01

    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.

    Understanding how quality improvement affects costs is important. Unfortunately, low-cost, reliable ways of measuring direct costs are scarce. This article builds on the principles of process improvement to develop a costing strategy that meets both criteria. Process-based costing has 4 steps: developing a flowchart, estimating resource use, valuing resources, and calculating direct costs. To illustrate the technique, this article uses it to cost the care planning process in 3 long-term care facilities. We conclude that process-based costing is easy to implement; generates reliable, valid data; and allows nursing managers to assess the costs of new or modified processes.

    Full Text Available Islam, through the Quran, proclaims that its mission includes the teachings to the whole universe, Everything in the universe is maintained by Islam, and none of the symptoms are ignored. The revelations also include the traditions of the Prophet that are authentic (shahih and good (hasan in quality. Both the Quran and maqbulah hadiths are accepted by Muslims on the basis of faith. When some experts of UIN Walisongo from various disciplines try to understand the sacred words of these two resources, their understanding continues, reaching the paradigm of the unity of science which essentially unites the normative, social, and natural sciences. The effect of this paradigm has brought up an issue for the author. Is there any hadiths or Prophetic traditions that can be used as a grand theory in the management disciplines of Islamic education.To address this issue, the authors conducted a literature research with the title Development of Islamic Education Management Module. Sources of data were focused on nine books of Hadiths : Sahih al-Bukhari, Sahih al-Muslim, Sunan Abu Dawud, Sunan at-Turmudzi, Sunan an-Nasai, Sunan Ibn Majah, Sunan ad-Darimi, Muwatta Malik, and Musnad Imam Ahmad bin Hanbal in the form of digital data Lidwa Reader Software Book 9 Imam Hadith. The findings of the study stated that the meaning of the word Rabb includes: creating, nurturing, maintaining, teaching, educating, and organizing. Thus, in an academic term, the word Rabb implies a manager or leader. Meanwhile, in the concept of comprehensive manager it contains at least 14 nomenclature denotations: planning, responsibility, organization, coordination, system of employee payroll, learning, resources, humanity, principle of making it easier for the manager to the employee, motivated to achieve optimal performance, preventing unproductivity, education participation, institutional costs, monitoring, and evaluation system.

    for voltage support of each generator is formed by a fixed and a variable cost. The fixed cost is calculated from the annual recovery factor of the capital invested in the generator. The variable cost depends on the operation conditions and on the cost for loss of opportunity of the generator. To determine the total cost for the voltage support of generators, it is considered that the market of active power has already been solved previously through an economic dispatch of active power. The systems used for the evaluation of the developed program are: a 5 nodes system and the IEEE 30 nodes system. [Spanish] Los cambios en las estructuras de los sistemas electricos de esquemas verticales a esquemas horizontales ha provocado que los sistemas esten formados por cuatro segmentos: generacion, transmision, distribucion y comercializacion.

Una de las tareas principales de esta organizacion junto con la red de transmision es la de realizar el movimiento de potencia desde los centros de generacion hasta los puntos de consumo, no obstante para poder llevar a cabo esta actividad se necesita un conjunto de servicios auxiliares. En un esquema horizontal, el soporte de voltaje por parte de los generadores es considerado como un servicio auxiliar, el cual es necesario para la operacion del sistema. Si bien la compensacion de potencia reactiva en un sistema electrico se debe realizar de manera local a traves de compensacion en derivacion, compensadores estaticos, condensadores sincronos y transformadores con cambiador en derivacion bajo carga, debido a que el transmitir flujos de potencia reactiva desde los generadores provoca un incremento en las perdidas del sistema de transmision; sin embargo aunque la funcion principal de los generadores sincronos es la produccion de potencia activa, de manera implicita estos generan potencia reactiva bajo ciertas condiciones

    Road crashes result in all kinds of social costs, such as medical costs, production loss, human losses, property damage, settlement costs and costs due to congestion. Studies into road crash costs and their trends are carried out quite regularly. In 2009, the costs amounted to € 12.5 billion, or 2.2% of the Gross Domestic Product (GDP). Insight into these costs is used for policy preparation and evaluation, and makes it possible to compare them with costs in other areas. Another important app...

    La Sociedad Colombiana de Historia de la Medicina, a través de su Junta Directiva, ha encargado al doctor Efraim Otero Ruiz y a quien les habla para rendir homenaje al Profesor Ernesto Andrade Valderrama. Honorífico pero difícil encargo, que he tomado con el mayor de los gustos y con el temor de no poder siquiera dibujar la bella parábola trazada por su vida hasta el presente. Aunque debo referirme fundamentalmente a su vida profesional, no puedo dejar de articular lo científico con lo humano.

    Ernesto Andrade Valderrama nació en esta ciudad de Bogotá, de una familia que reunió las mejores virtudes Santafereñas y Santandereanas; su padre Eugenio Andrade Suescún fue Gobernador de Santander durante el gobierno del General Ramón González Valencia y Secretario (Ministro del Tesoro durante la administración del Presidente Jorge Holguín. Su familia fue formada bajo principios cristianos orientados al servicio de sus semejantes. Por ello no es de extrañarnos que de los 17 hijos de Don Eugenio Andrade, cinco se hubiesen dedicado al sacerdocio, 3 de ellos jesuitas, uno de los cuales, Bernardo, fue misionero en la China y quien lastimosamente falleció ahogado al tratar de rescatar a un niño durante el naufragio del barco en que regresaba del oriente, frente a las costas italianas.

    2015-04-01

    When cardiac arrest occurs, timely competent advanced life support (ALS) interventions by nursing staff can influence patient outcomes. Ongoing ALS education influences maintenance of competency and avoids skill decay. To explore the methods of ALS education delivery for nurses in the workplace; describe the issues relating to maintaining ALS competency; explore ALS competency decay for nurses and develop recommendations for the provision of continuing ALS education. A qualitative exploratory design was used to study ALS education provision in the workplace. Data were collected from ALS nurse experts in Western Australia by face-to-face and phone interviews. Semi-structured interviews were conducted and organised around a set of predetermined questions. Two major themes were identified; the first theme Demand and Supply describes the increasing demand for ALS education for nurses and the challenges with providing timely cost effective traditional face-to-face ALS education. The second theme, Choosing The Best Education Options describes new ways to provide ALS education using emerging technologies. The study suggested that using e-learning methods would assist with educating the maximum amount of nurses in a timely manner and e-learning and teleconferencing offer opportunities to reach nurses in distant locations. Delivering ALS education more frequently than annually would increase skills maintenance and lessen skill decay. Further research is required to explore which blended e-learning model is best suited to ALS education. Copyright © 2014 Elsevier Ltd. All rights reserved.

    In task-switching paradigms, performance is better when repeating the same task than when alternating between tasks (switch cost) and when repeating a task alone rather than intermixed with another task (mixing cost). These costs remain even after extensive practice and when task cues enable advanced preparation (residual costs). Moreover, residual reaction time mixing cost has been consistently shown to increase with age. Residual switch and mixing costs modulate the amplitude of the stimulus-locked P3b. This mixing effect is disproportionately larger in older adults who also prepare more for and respond more cautiously on these "mixed" repeat trials (Karayanidis et al., 2011). In this paper, we analyze stimulus-locked and response-locked P3 and lateralized readiness potentials to identify whether residual switch and mixing cost arise from the need to control interference at the level of stimulus processing or response processing. Residual mixing cost was associated with control of stimulus-level interference, whereas residual switch cost was also associated with a delay in response selection. In older adults, the disproportionate increase in mixing cost was associated with greater interference at the level of decision-response mapping and response programming for repeat trials in mixed-task blocks. These findings suggest that older adults strategically recruit greater proactive and reactive control to overcome increased susceptibility to post-stimulus interference. This interpretation is consistent with recruitment of compensatory strategies to compensate for reduced repetition benefit rather than an overall decline on cognitive flexibility.

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.

    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.

    Full Text Available Introducción. La enfermedad de Chagas, causada por Trypanosoma cruzi, es uno de los problemas más graves de salud pública en el continente americano. El benzonidazol es uno de los dos medicamentos utilizados para tratar la enfermedad de Chagas. Sin embargo, la variación de la sensibilidad del parásito a este medicamento es una de las principales causas del fracaso del tratamiento. Objetivo. Evaluar la sensibilidad in vitro al benzonidazol de cepas colombianas de T. cruzi de diferentes orígenes y procedencia geográfica. Materiales y métodos. Treinta y tres cepas colombianas de T. cruzi aisladas de humanos, vectores y mamíferos, se analizaron in vitro mediante el micrométodo enzimático de MTT para determinar la concentración inhibitoria 50 (CI50 al benzonidazol. Se estudió la correlación entre la sensibilidad in vitro al medicamento y diferentes parámetros biológicos y eco-epidemiológicos. Resultados. El análisis de sensibilidad al medicamento indicó que el 36 % de las cepas eran sensibles, el 48 %, parcialmente resistentes y, el 16 %, resistentes al benzonidazol. Los análisis de correlación entre las CI50 con algunos parámetros biológicos y eco-epidemiológicos, mostraron diferencias en cuanto a la sensibilidad según el origen biológico y el área geográfica de procedencia de la cepa. Conclusiones. Existe una gran variabilidad en cuanto a la sensibilidad al benzonidazol de las cepas circulantes de T. cruzi en Colombia, lo cual sugiere la presencia de cepas naturalmente resistentes en el país.   doi: http://dx.doi.org/10.7705/biomedica.v32i2.458

    Glucagon-like peptide-1 receptor agonists (GLP-1 RA) are relatively new medications for diabetes that offer a weight-loss profile that can be considered desirable for patients with both type 2 diabetes (T2D) and obesity. GLP-1 RA are effective in combination with insulin, and even slightly superior or at least equal to short-acting insulin in T2D; however, since they work in the incretin system, they may not be effective in long-standing disease. Additionally, only recently have publications reported their cardiovascular safety, and there is limited evidence for long-term effectiveness. The work presented by Huetson et al. offers a much needed perspective through a medical economic model for the long term cost-effectiveness of GLP-1 RA. The authors found benefits in quality-adjusted life years and reduced lifetime healthcare costs. While there are a few limitations, this study contributes to the understanding of these agents and their impact on the epidemics of obesity in T2D, where weight management is no longer an option, but an essential component of the diabetes plan of care.

    2016-05-01

    This paper presents a methodology for a heliostat cost optimization study. First different variants of small, medium sized and large heliostats are designed. Then the respective costs, tracking and optical quality are determined. For the calculation of optical quality a structural model of the heliostat is programmed and analyzed using finite element software. The costs are determined based on inquiries and from experience with similar structures. Eventually the levelised electricity costs for a reference power tower plant are calculated. Before each annual simulation run the heliostat field is optimized. Calculated LCOEs are then used to identify the most suitable option(s). Finally, the conclusions and findings of this extensive cost study are used to define the concept of a new cost-efficient heliostat called `Stellio'.

    This paper deals with empirical computation of Aumann–Shapley cost shares for joint production. We show that if one uses a mathematical programing approach with its non-parametric estimation of the cost function there may be observations in the data set for which we have multiple Aumann......–Shapley prices. We suggest to overcome such problems by using lexicographic goal programing techniques. Moreover, cost allocation based on the cost function is unable to account for differences between efficient and actual cost. We suggest to employ the notion of rational inefficiency in order to supply a set...... of assumptions concerning firm behavior. These assumptions enable us to connect inefficient with efficient production and thereby provide consistent ways of allocating the costs arising from inefficiency....

  3. Avoidable waste management costs

    1995-01-01

    This report describes the activity based costing method used to acquire variable (volume dependent or avoidable) waste management cost data for routine operations at Department of Energy (DOE) facilities. Waste volumes from environmental restoration, facility stabilization activities, and legacy waste were specifically excluded from this effort. A core team consisting of Idaho National Engineering Laboratory, Los Alamos National Laboratory, Rocky Flats Environmental Technology Site, and Oak Ridge Reservation developed and piloted the methodology, which can be used to determine avoidable waste management costs. The method developed to gather information was based on activity based costing, which is a common industrial engineering technique. Sites submitted separate flow diagrams that showed the progression of work from activity to activity for each waste type or treatability group. Each activity on a flow diagram was described in a narrative, which detailed the scope of the activity. Labor and material costs based on a unit quantity of waste being processed were then summed to generate a total cost for that flow diagram. Cross-complex values were calculated by determining a weighted average for each waste type or treatability group based on the volume generated. This study will provide DOE and contractors with a better understanding of waste management processes and their associated costs. Other potential benefits include providing cost data for sites to perform consistent cost/benefit analysis of waste minimization and pollution prevention (WMIN/PP) options identified during pollution prevention opportunity assessments and providing a means for prioritizing and allocating limited resources for WMIN/PP.

    2013-10-01

    Current economic conditions and budget constraints in publicly funded biomedical research have brought about a renewed interest in analyzing the cost and economic viability of research infrastructures. However, there are no proposals for specific cost accounting models for these types of organizations in the international scientific literature. The aim of this paper is to present the basis of a cost analysis model useful for any biobank regardless of the human biological samples that it stores for biomedical research. The development of a unique cost model for biobanks can be a complicated task due to the diversity of the biological samples they store. Different types of samples (DNA, tumor tissues, blood, serum, etc.) require different production processes. Nonetheless, the common basic steps of the production process can be identified. Thus, the costs incurred in each step can be analyzed in detail to provide cost information. Six stages and four cost objects were obtained by taking the production processes of biobanks belonging to the Spanish National Biobank Network as a starting point. Templates and examples are provided to help managers to identify and classify the costs involved in their own biobanks to implement the model. The application of this methodology will provide accurate information on cost objects, along with useful information to give an economic value to the stored samples, to analyze the efficiency of the production process and to evaluate the viability of some sample collections.

    There are many costs associated with parenteral nutrition: physician time, nursing time, biochemical monitoring, patient education, ancillary equipment and the nutrition solutions themselves. The solutions are easily identified as responsible for a large proportion of these costs. There are several strategies that can be used to help control pharmacy costs, such as selection of ingredients, purchasing contracts, standardized formulae and prescribing procedures, preprinted doctor's order forms, automated manufacturing and labelling processes, patient monitoring, all-in-one preparation, and contracted manufacturing services. Individual pharmacies need to know what options are available in order to select those that, in the context of their own institutions, can lead to cost savings and improved efficiency.

Hasta hace poco se consideraba que nuestro cerebro se benefició de la reducción de otros órganos de alto consumo energético para posibilitar su aumento de tamaño, pero nuevos resultados indican que semejante reducción no tuvo lugar ni en mamíferos ni en primates. En cambio, todo parece indicar que la reducción de costes de locomoción, con la adquisición del bipedalismo, pudo contribuir al aumento de tamaño de nuestros cerebros.

    Full Text Available Los desafíos y amenazas de la globalización afecta no solamente al mundo de las empresas y de los gobiernos. Toda la cultura de la modernidad está en entredicho. No obstante, debemos comenzar por tratar de precisar el concepto, y en especial, diferenciar entre “globalidad” y “globalización”. Veremos luego que uno de los nudos centrales de la estrategia neoliberal de la globalización consiste en someter el “trabajo conceptual” a un proceso de “subsunción” similar al que la revolución industrial realizó en el caso del “trabajo directo”, estrategia que en el plano ideológico se esconde detrás de la ideología del “capital humano”.De manera similar, la expoliación de la naturaleza que está en curso pretende racionalizarse a partir del concepto de “capital natural”. La crítica de esta estrategia es fundamental para hacer visible la urgente necesidad de desarrollar una cultura de la esperanza y de la responsabilidad por el bien común, en la cual el pensamiento crítico juega un papel fundamental. Sólo a partir de esta cultura de la responsabilidad es posible pensar en propuestas y políticas alternativas frente al capitalismo globalizado, articuladas a partir de la reivindicación de los derechos humanos.

    In the 199os, Hewlett-Packard's PC business was struggling to turn a dollar, despite the company's success in winning market share. By 1997, margins on its PCs were as thin as a silicon wafer, and some product lines hadn't turned a profit since 1993. The problem had everything to do with the PC industry's notoriously short product cycles and brutal product and component price deflation. A common rule of thumb was that the value of a fully assembled PC decreased 1% a week. In such an environment, inventory costs become critical. But not just the inventory costs companies traditionally track, HP found, after a thorough review of the problem. The standard "holding cost of inventory"--the capital and physical costs of inventory--accounted for only about 10% of HP's inventory costs. The greater risks, it turned out, resided in four other, essentially hidden costs, which stemmed from mismatches between demand and supply: Component devaluation costs for components still held in production; Price protection costs incurred when product prices drop on the goods distributors still have on their shelves; Product return costs that have to be absorbed when distributors return and receive refunds on overstock items, and; Obsolescence costs for products still unsold when new models are introduced. By developing metrics to track those costs in a consistent way throughout the PC division, HP has found it can manage its supply chains with much more sophistication. Gone are the days of across-the-board measures such as,"Everyone must cut inventories by 20% by the end of the year," which usually resulted in a flurry of cookie-cutter lean production and just-in-time initiatives. Now, each product group is free to choose the supply chain configuration that best suits its needs. Other companies can follow HP's example.

  15. Stereo Disparity through Cost Aggregation with Guided Filter

    Directory of Open Access Journals (Sweden)

    Pauline Tan

    2014-10-01

    Full Text Available Estimating the depth, or equivalently the disparity, of a stereo scene is a challenging problem in computer vision. The method proposed by Rhemann et al. in 2011 is based on a filtering of the cost volume, which gives for each pixel and for each hypothesized disparity a cost derived from pixel-by-pixel comparison. The filtering is performed by the guided filter proposed by He et al. in 2010. It computes a weighted local average of the costs. The weights are such that similar pixels tend to have similar costs. Eventually, a winner-take-all strategy selects the disparity with the minimal cost for each pixel. Non-consistent labels according to left-right consistency are rejected; a densification step can then be launched to fill the disparity map. The method can be used to solve other labeling problems (optical flow, segmentation but this article focuses on the stereo matching problem.

    The change in the microstructural parameters and microhardness values in 6.5 MeV proton irradiated pure Al and Al5083 alloy samples have been evaluated using different model based techniques of X-ray diffraction Line Profile Analysis (XRD) and microindendation techniques. The detailed line profile analysis of the XRD data showed that the domain size increases and saturates with irradiation dose both in the case of Al and Al5083 alloy. The corresponding microstrain values did not show any change with irradiation dose in the case of the pure Al but showed an increase at higher irradiation doses in the case of Al5083 alloy. The microindendation results showed that unirradiated Al5083 alloy has higher hardness value compared to that of unirradiated pure Al. The hardness increased marginally with irradiation dose in the case of Al5083, whereas for pure Al, there was no significant change with dose.

    BACKGROUND: To estimate the direct and indirect costs of stroke in patients and their partners. DESCRIPTION: Direct and indirect costs were calculated using records from the Danish National Patient Registry from 93,047 ischemic, 26,012 hemorrhagic and 128,824 unspecified stroke patients...... and compared with 364,433, 103,741 and 500,490 matched controls, respectively. RESULTS: Independent of age and gender, stroke patients had significantly higher rates of mortality, health-related contacts, medication use and lower employment, lower income and higher social-transfer payments than controls....... The attributable cost of direct net health care costs after the stroke (general practitioner services, hospital services, and medication) and indirect costs (loss of labor market income) were €10,720, €8,205 and €7,377 for patients, and €989, €1,544 and €1.645 for their partners, over and above that of controls...

    Based on the well-known fact that social networks can provide effective mechanisms that help to increase the trust level between two trade partners, we apply a simple game-theoretical framework to derive transaction costs as a high risk of opportunistic behavior in a repeated trade relation...... transaction cost functions for all traded farm inputs and outputs. Estimation results based on a sample of 315 Polish farms imply a significant influence of social network structures on farm’s transaction costs. Moreover, estimated transaction costs correspond to a reasonable amount of farm specific shadow...... determined by the density and size of trading networks. In the empirical part of the paper we apply a two stage procedure to estimate the impact of social network structures on farm’s transaction costs observed for different input and output markets.

    To make sure the intermediate products of the carbothermic reduction of Al2O3 process, such as Al4CO4, Al2CO and Al4C3, and the interaction of AlCl, AlCl2, AlCl3 with Al4CO4, Al2CO and Al4C3, respectively, thermodynamic analyses were used to study the chloride reaction production of them under the vacuum situation. 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.

    Full Text Available The One Anastomosis Gastric Bypass has been developed from the Mini Gastric Bypass procedure as originally described by Robert Rutledge. The modification of the original procedure consists of making a latero-lateral gastro-jejunal anastomosis instead of a termino-lateral anastomosis, as is carried out as described in the original procedure. The rationale for these changes is to try to reduce exposure of the gastric mucosa to biliopancreatic secretions because of their potentially carcinogenic effects with longer term exposure, which is the major criticism of the original technique. If we fix the jejunal loop to the gastric pouch some centimetres up to the gastro-jejunal anastomosis the biliopancreatic secretions have less possibility of coming into the gastric cavity (gravity force. Furthermore, if the anastomosis is latero-lateral this possibility is reduced even more. In addition, the intestinal loop reinforces the staple line against disruption, and also the gastric pouch against dilatation.El Bypass Gástrico de Una Anastomosis se ha desarrollado a partir del Mini Bypass Gástrico descrito por Robert Rutledge. La modificación del procedimiento original consiste en hacer una anastomosis latero-lateral en lugar de termino-lateral como se hace en la técnica original.

Al fijar el asa de yeyuno a la nueva bolsa gástrica unos centímetros por encima de la anastomosis gastro-yeyunal, la secreción bilio-pancreática tiene menos posibilidades de entrar en la cavidad gástrica (fuerza de gravedad. Al ser la anastomosis latero-lateral esta posibilidad se reduce aún más. Además, el asa de yeyuno refuerza la línea de grapas contra su disrupción y previene la posible dilatación de la bolsa gástrica.

  17. Cultural Differences in Opportunity Cost Consideration

    Two studies were conducted to investigate cultural differences in opportunity cost consideration between Chinese and Euro-Canadians. Opportunity cost is defined as the cost of a benefit that must be forgone in order to pursue a better alternative (Becker et al., 1974). In both studies, participants read about hypothetical purchase scenarios, and then decided whether they would buy a certain product. Opportunity cost consideration was measured in two ways: (1) participants' thoughts pertaining to other (nonfocal) products while making decisions; (2) participants' decisions not to buy a focal product (Study 1) or a more expensive product (Study 2). Across both indexes, we found that after controlling for individual difference variables and amount of pocket money, Chinese participants in China considered financial opportunity cost more than Euro-Canadians in Study 1. Similar results were observed in Study 2 when comparing Chinese in Canada with Euro-Canadians However, the cultural effect on opportunity cost consideration was confounded by family income in Study 2. Implications for resource management, limitations of the current research and directions for future research are discussed. PMID:28184202

    Full Text Available Fabrication of Al-Al3Ti functionally graded materials (FGMs under the centrifugal force has recently attracted some attention. The controlled compositional gradient of the fabricated FGMs, the low cost of the process, and the good mold filling, are the main advantages of the centrifugal method (CM. Using the conventional CM techniques such as the centrifugal solid-particle method and centrifugal in-situ method, FGMs rings with gradually distributed properties could be achieved. As a more practical choice, the centrifugal mixed-powder method (CMPM was recently proposed to obtain FGMs containing nano-particles selectively dispersed in the outer surface of the fabricated parts. However, if a control of the particles morphology, compound formulas or sizes, is desired, another CM technique is favored. As a development of CMPM, our novel reaction centrifugal mixed-powder method (RCMPM has been presented. Using RCMPM, Al‑Al3Ti/Ti3Al FGMs with good surface properties and temperature controlled compositional gradient could be achieved. In this short review, this novel method will be discussed in detail and the effect of RCMPM processing temperature on the reinforcement particles morphology, size and distribution through the fabricated samples, will be reviewed.

    Full Text Available El bajo peso al nacer (BPN ha constituido un enigma en la ciencia a través de los tiempos. Múltiples son las investigaciones realizadas acerca de las causas que lo producen y las consecuencias que provoca. Su importancia no solo radica en lo que significa en la morbilidad y la mortalidad infantil, sino que estos niños tienen habitualmente múltiples problemas posteriores. El Programa para la Reducción del BPN señala que los niños nacidos con un peso inferior a los 2 500 g presentan riesgo de mortalidad 14 veces mayor durante el primer año de vida, en comparación con los niños que nacen con un peso normal a término. Dentro de los factores de riesgo del BPN se han encontrado con mayor frecuencia en estudios realizados por diferentes autores, los siguientes: el embarazo en la adolescencia, la desnutrición en la madre, el hábito de fumar, la hipertensión arterial durante el embarazo, la sepsis cervicovaginal, la anemia y los embarazos gemelares, entre otros. Es innegable la influencia que el BPN tiene sobre las futuras generaciones, por lo que debe constituir la diana de los esfuerzos que el médico y la enfermera deben desarrollar en su prevención, sobre todo en la comunidadLow birth weight has been an enigma for Science through times. A lot of research works have been carried out about its causes and consequences. The importance of LBW not only lies in its meaning for infant mortality and morbidity but also in the many problems that low birth weight children regularly face in the future. The program for the reduction of LBW points out that newborns weighing under 2500g have during his/her first year of life a mortality risk 14 times higher than newborns with a normal weight at term. Among the low birth weight risk factors, a number of studies by various authors have frequently found the following; pregnancy at adolescence; undernourishment in mothers, smoking, blood hypertension during pregnancy, cervix-vaginal sepsis; anemia, twin

    Full Text Available ENGLISH: During the last decades, the topos religion transformed into a powerful category of difference, which is also relevant for educationsystems and settings. Religion as a tool to differentiate between subjects is linked with power and dominance and, thus,with ideas about the constructed identities of “the other”. With this respects, religion functions as a code to define in- andexclusions and mark “the other”, e.g. “the Muslim” in predominantly Christian societies in Europe. Critical theories on racismenable to recognize, describe and define these practices and their effects. They can provide a useful tool to question and challengeintercultural and interreligious educational approaches which potentially reproduce and, thus, strengthen cultural/religiousdifferentiations. DEUTSCH: Die Differenz- und Heterogenitätskategorie Religion hat sich in den letzten Jahren im europäischen und auch deutschsprachigenDiskursraum zu einer medial, wissenschaftlich und politisch wirkmächtigen Kategorie entwickelt. Dabei zeigt sich Religion sowohlals soziale Unterscheidungspraxis (auch in pädagogischen Arrangements, als auch als Mittel zur Identifikation und Charakterisierungbestimmter Gruppen und Individuen als religiöse Subjekte. Religion stellt in diesem Zusammenhang einen Zugehörigkeitscodedar, mit dem Personen als natio-ethno-kulturell Andere markiert werden, wie die Markierung von MuslimInnen durchAngehörige der mehrheitlich christlichen Dominanzgesellschaft zeigt.

  16. Analyzing EUV mask costs

    Lercel, Michael; Kasprowicz, Bryan

    2016-10-01

    The introduction of Extreme Ultraviolet Lithography (EUV) as a replacement for multiple patterning is based on improvements of cycle time, yield, and cost. Earlier cost studies have assumed a simple assumption that EUV masks (being more complex with the multilayer coated blank) are not more than three times as expensive as advanced ArFi (ArF immersion) masks. EUV masks are expected to be more expensive during the ramp of the technology because of the added cost of the complex mask blank, the use of EUV specific mask tools, and a ramp of yield learning relative to the more mature technologies. This study concludes that, within a range of scenarios, the hypothesis that EUV mask costs are not more than three times that of advanced ArFi masks is valid and conservative.

  17. Biosimilar Insulin and Costs

    Science.gov (United States)

    Heinemann, Lutz

    2015-01-01

    The costs for insulin treatment are high, and the steady increase in the number of patients with diabetes on insulin presents a true challenge to health care systems. Therefore, all measures to lower these costs are welcomed by patients, physicians, and health care providers. The market introduction of biosimilar insulins presents an option to lower treatment costs as biosimilars are usually offered at a lower price than the originator product. However, the assumption that a drastic reduction in insulin prices will take place, as was observed with many generic drugs, is most probably not realistic. As the first biosimilar insulin has now been approved in the EU, this commentary discusses a number of aspects that are relevant when it comes to the potential cost reduction we will see with the use of biosimilar insulins.

    In France at the present time, there is no comprehensive registry of hand injuries. Three types of occurrences; motor vehicle accidents, work accidents, and accidents incident to activities of daily living, are covered by different types of insurance. It is the individual insurance companies, payers of the indemnification, who maintain registries of these accidents. Statistics on work accidents are very detailed and consistent, but they are oriented toward risk management. The aggregate cost of traumatic injuries to the hand is not known. Only large financial institutions are equipped to determine appropriate preventive measures and to establish premium rates based on loss experience. In 2001, hand injuries accounted for 27% of work accidents causing loss of work of at least 1 day. About 29.8% of these work accidents caused permanent partial impairment. About 17.7% of total days lost and 18.2% of the total costs of permanent impairment were due to hand injuries. In the system of compensation for work accidents, there is a major difference in the cost according to the severity of the impairment. If the permanent impairment is equal to or less than 9%, a lump sum payment is made, but if the permanent impairment is over 9%, the worker receives regular payments for the rest of his life. In 2000, the average cost of a work injury with partial permanent impairment of over 9% was [symbol: see text] 85,405, while the average cost of a lump sum settlement was only [symbol: see text] 1479, a ratio of 57 to 1. The compensation costs represent 80% of the cost of work accidents, while the cost of treatment, including all providers and institutions, makes up only 20% of the cost. Compensation for sequelae of accidents in the course of daily life is new for the insurance companies, although these accidents are frequent and often cause significant repercussions in the professional lives of victims because of the loss of hand function.

    Full Text Available Muscoloskeletal disorders are the first cause of disability and the second cause of permanent disablement in Italy. Osteoarthritis is the most frequent rheumatic disease and affects about 4 million Italians. In spite of that, data concerning social costs are lacking. On account of this lack we measured sanitary costs of 314 patients suffering from osteoarthritis. A retrospective, prevalence- based multicentric study was performed using a bottom-up approach. The study period was 12 months and referred to 1999. Eight percent of patients didn’t take any drug for the treatment of osteoarthritis; NSAIDs were prescribed to 86.9% of patients, analgesics to 29.9%, chondroprotective drugs to 7.6%, and gastroprotective drugs to 36.9%. Total sanitary costs came to 455 € / patient / year: 122 € were spent on diagnostics, 293 € on therapy and 40 € on management of drug-related gastropathy. Since the costs of anti-inflammatory drugs came to 30 € we calculated iatrogenic cost factor of 2.3. Moreover, the study supplied interesting informations about prescriptive habits, which differ in Italy from international guidelines for the medical treatment of OA, about patient management, because of hospitalization, which by itself absorbs 1/3 of resources, and about physiotherapy, which costs twice as much as pharmacological therapy. At last, data analysis gave the cue for suggestions on changing patients’ management.

  4. Reactive control processes contributing to residual switch cost and mixing cost in young and old adults

    Directory of Open Access Journals (Sweden)

    Lisa Rebecca Whitson

    2014-04-01

    Full Text Available In task-switching paradigms, performance is better when repeating the same task than when alternating between tasks (switch cost and when repeating a task alone rather than intermixed with another task (mixing cost. These costs remain even after extensive practice and when task cues enable advanced preparation (residual costs. Moreover, residual RT mixing cost has been consistently shown to increase with age. Residual switch and mixing costs modulate the amplitude of the stimulus-locked P3b. This mixing effect is disproportionately larger in older adults who also prepare more for and respond more cautiously on these ‘mixed’ repeat trials (Karayanidis et al., 2011. In this study, we examine stimulus-locked and response-locked P3 and lateralized readiness potentials to identify whether residual switch and mixing cost arise from the need to control interference at the level of stimulus processing or response processing. Residual mixing cost was associated with control of stimulus-level interference, whereas residual switch cost was also associated with a delay in response selection. In older adults, the disproportionate increase in mixing cost was associated with greater interference at the level of decision-response mapping and response programming for repeat trials in mixed-task blocks. We argue that, together with evidence of greater proactive control and more cautious responding for these trials, these findings suggest that older adults strategically recruit greater proactive and reactive control to overcome increased susceptibility to post-stimulus interference. This interpretation is consistent with recruitment of compensatory strategies to compensate for reduced repetition benefit rather than an overall decline on cognitive flexibility.

  5. How much does curation cost?

    Science.gov (United States)

    Karp, Peter D

    2016-01-01

    NIH administrators have recently expressed concerns about the cost of curation for biological databases. However, they did not articulate the exact costs of curation. Here we calculate the cost of biocuration of articles for the EcoCyc database as $219 per article over a 5-year period. That cost is 6-15% of the cost of open-access publication fees for publishing biomedical articles, and we estimate that cost is 0.088% of the cost of the overall research project that generated the experimental results. Thus, curation costs are small in an absolute sense, and represent a miniscule fraction of the cost of the research.

    Full Text Available Considerando el conflicto como algo natural en las relaciones interpersonales, el artículo expone la aproximación a su estudio desde el entendimiento de la dinámica del conflicto como una dinámica caótica. Y ello debido, en parte, al razonamiento teórico de que no linealidad más iteración generan caos (Edward Lorenz. Hoy sabemos que el caos ha de ser entendido bajo un nuevo prisma: como potencial generador de nuevas estructuras y formas, algo similar al cambio de actitud que sucedió con respecto al conflicto al abandonar los planteamientos funcionalistas. Bajo este prisma, aún se entiende mejor el porqué el conflicto puede contribuir al cambio. En el artículo también se tratarán otras implicaciones de entender el conflicto como proceso caótico, tales como la inoperancia de estudios transversales, desde un punto de vista metodológico, la utilidad del conflicto -en tanto proceso caóticocomo generador de nuevos órdenes y la aplicación de la teoría de los atractores para su mejor comprensión. Finalmente, se abordará la problemática de la gestión de conflictos desde una perspectiva de una gestión del caos.

  4. Underestimation of Project Costs

    Science.gov (United States)

    Jones, Harry W.

    2015-01-01

    Large projects almost always exceed their budgets. Estimating cost is difficult and estimated costs are usually too low. Three different reasons are suggested: bad luck, overoptimism, and deliberate underestimation. Project management can usually point to project difficulty and complexity, technical uncertainty, stakeholder conflicts, scope changes, unforeseen events, and other not really unpredictable bad luck. Project planning is usually over-optimistic, so the likelihood and impact of bad luck is systematically underestimated. Project plans reflect optimism and hope for success in a supposedly unique new effort rather than rational expectations based on historical data. Past project problems are claimed to be irrelevant because "This time it's different." Some bad luck is inevitable and reasonable optimism is understandable, but deliberate deception must be condemned. In a competitive environment, project planners and advocates often deliberately underestimate costs to help gain project approval and funding. Project benefits, cost savings, and probability of success are exaggerated and key risks ignored. Project advocates have incentives to distort information and conceal difficulties from project approvers. One naively suggested cure is more openness, honesty, and group adherence to shared overall goals. A more realistic alternative is threatening overrun projects with cancellation. Neither approach seems to solve the problem. A better method to avoid the delusions of over-optimism and the deceptions of biased advocacy is to base the project cost estimate on the actual costs of a large group of similar projects. Over optimism and deception can continue beyond the planning phase and into project execution. Hard milestones based on verified tests and demonstrations can provide a reality check.

    Seal durability is critical to achieving the 2010 DOE operational life goals for both stationary and transportation PEM fuel cell stacks. The seal material must be chemically and mechanically stable in an environment consisting of aggressive operating temperatures, humidified gases, and acidic membranes. The seal must also be producible at low cost. Currentlyused seal materials do not meet all these requirements. This project developed and demonstrated a high consistency hydrocarbon rubber seal material that was able to meet the DOE technical and cost targets. Significant emphasis was placed on characterization of the material and full scale molding demonstrations.

    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.

    Power towers are capable of producing solar-generated electricity and hydrogen on a large scale. Heliostats are the most important cost element of a solar power tower plant. Since they constitute {approx} 50% of the capital cost of the plant it is important to reduce heliostat cost as much as possible to improve the economic performance of power towers. In this study we evaluate current heliostat technology and estimate a price of $126/m{sup 2} given year-2006 materials and labor costs for a deployment of {approx}600 MW of power towers per year. This 2006 price yields electricity at $0.067/kWh and hydrogen at $3.20/kg. We propose research and development that should ultimately lead to a price as low as $90/m{sup 2}, which equates to $0.056/kWh and $2.75/kg H{sup 2}. Approximately 30 heliostat and manufacturing experts from the United States, Europe, and Australia contributed to the content of this report during two separate workshops conducted at the National Solar Thermal Test Facility.

    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.

    Withers, G.

    2007-03-15

    Low cost, light weight Ultalite{reg_sign} is an Aluminium Metal Matrix Composite (AL-MMC) which utilises wear resistant ceramic particles derived from flyash. Ultalite AL-MMC typically contains between 10 and 30 per cent ceramic particles, and is formulated for the manufacture of wear resistant automotive components. Due to its low density and ease of processing into net shape die casting, Ultalite AL-MMC provides weight savings of up to 60 per cent over components fabricated from cast iron, thereby providing improved fuel efficiency with reduced greenhouse emissions. The original flyash material was sourced from a black coal power station in Queensland, where it contained a wide range of particles sizes. To narrow the size range and to remove impurities, a proprietary pretreatment developed by Dr Thomas Robl and co-researchers at the University of Kentucky was employed. The University of Kentucky developed the technology for the classification and benefaction of flyash to produce high-grade Pozzolan, which is used in Portland Cement product. This technology is now being applied to the production of Ultalite AL-MMC. Testing performed by Dr Robl has shown that the proprietary technology can eliminate the hollow particles, extract detrimental carbon-based impurities and remove the extremely fine and coarse particles. All that remains are dense ceramic particles with an average particle size of approximately 30 {mu}m. 9 refs., 3 figs.

    Recent advances in pharmacology, diagnostic and invasive procedures provide a series of modalities that diminish the morbidity and increase the long term survival in the patients that have suffered a heart attack to myocardium. The stratification by risk is an essential element for the handling of the survivors of heart attack to myocardium. In their attention it is looked for to optimize the therapeutic benefit, to diminish the unnecessary diagnostic and therapeutic procedures and to improve the efficiency. For example, a coronariography in sick with heart attack to myocardium it is not cost-effective if not is clinically suitable. Of there that from the institutional point of view, this is, of the Mexican Institute of the Public Health, they are required of appropriate reference approaches and counter reference to grant to the sick person, the best service that is the one in this case the diagnostic and the handling of the ischemic cardiopathy with the smallest waste of resources. The estimation of the annual survival is the base of the stratification, it constitutes the angular stone of the early handling of the heart attack to myocardium. The goal for the clinical would be to identify patients with intermediate risk, since, this risk makes them candidates to therapy interventionist. As long as those with low risk won't require intervention. This would allow the decrease of rates by revenues of heart attack to myocardium, and therefore to diminish the hospital staying rates. The Nuclear Cardiology (myocardial gammagraphy) it is not the only invasive method available to evaluate the myocardial perfusion in sick in who coronary illness is suspected. When the myocardial gammagraphy is carried out in appropriate population, the cost it diminishes because it restricts the necessity of additional invasive evaluations. This because the nuclear cardiology has predictive value so much for the mortality like to detect myocardial viability. Based on these

  10. The Yale Cost Model and cost centres: servant or master?

    Science.gov (United States)

    Rigby, E

    1993-01-01

    Cost accounting describes that aspect of accounting which collects, allocates and controls the cost of producing a service. Costing information is primarily reported to management to enable control of costs and to ensure the financial viability of units, departments and divisions. As costing studies continue to produce estimates of Diagnosis Related Group (DRG) costs in New South Wales hospitals, as well as in other states, costs for different hospitals are being externally compared, using a tool which is usually related to internal management and reporting. Comparability of costs is assumed even though accounting systems differ. This paper examines the cost centre structures at five major teaching hospitals in Sydney. It describes the similarities and differences in how the cost centres were constituted, and then details the line items of expenditure that are charged to each cost centre. The results of a comparative study of a medical specialty are included as evidence of different costing methodologies in the hospitals. The picture that emerged from the study is that the hospitals are constituting their cost centres to meet their internal management needs, that is, to know the cost of running a ward or nursing unit, a medical specialty, department and so on. The rationale for the particular cost centre construction was that cost centre managers could manage and control costs and assign responsibility. There are variations in procedures for assigning costs to cost centres, and the question is asked 'Do these variations in procedures make a material difference to our ability to compare costs per Diagnosis Related Group at the various hospitals?' It is contended that the accounting information, which is produced as a result of different practices, is primarily for internal management, not external comparison. It would be better for hospitals to compare their estimated costs per Diagnosis Related Group to an internal standard cost rather than the costs from other

  11. Phenotypic plasticity, costs of phenotypes, and costs of plasticity

    DEFF Research Database (Denmark)

    Callahan, Hilary S; Maughan, Heather; Steiner, Uli

    2008-01-01

    Why are some traits constitutive and others inducible? The term costs often appears in work addressing this issue but may be ambiguously defined. This review distinguishes two conceptually distinct types of costs: phenotypic costs and plasticity costs. Phenotypic costs are assessed from patterns...... of covariation, typically between a focal trait and a separate trait relevant to fitness. Plasticity costs, separable from phenotypic costs, are gauged by comparing the fitness of genotypes with equivalent phenotypes within two environments but differing in plasticity and fitness. Subtleties associated with both...... types of costs are illustrated by a body of work addressing predator-induced plasticity. Such subtleties, and potential interplay between the two types of costs, have also been addressed, often in studies involving genetic model organisms. In some instances, investigators have pinpointed the mechanistic...

He suggests an increased use of satellite imagery in the mapping of geothermal resources and the identification of hot spots. Also, coordinating with oil and gas exploration efforts, the efficiency of the exploration task could be optimized.

    A tool is presented to quantify the risks of geothermal projects, the Geothermal Probabilistic Cost Model (GPCM). The GPCM model is used to evaluate a geothermal reservoir for a binary-cycle electric plant at Heber, California. Three institutional aspects of the geothermal risk which can shift the risk among different agents are analyzed. The leasing of geothermal land, contracting between the producer and the user of the geothermal heat, and insurance against faulty performance are examined. (MHR)

    Full Text Available Introduction. Cost of anaesthesiology represent defined measures to determine a precise profile of expenditure estimation of surgical treatment, which is important regarding planning of healthcare activities, prices and budget. Objective. In order to determine the actual value of anaestesiological services, we started with the analysis of activity based costing (ABC analysis. Methods. Retrospectively, in 2005 and 2006, we estimated the direct costs of anestesiological services (salaries, drugs, supplying materials and other: analyses and equipment. of the Institute of Anaesthesia and Resuscitation of the Clinical Centre of Serbia. The group included all anesthetized patients of both sexes and all ages. We compared direct costs with direct expenditure, “each cost object (service or unit” of the Republican Health-care Insurance. The Summary data of the Departments of Anaesthesia documented in the database of the Clinical Centre of Serbia. Numerical data were utilized and the numerical data were estimated and analyzed by computer programs Microsoft Office Excel 2003 and SPSS for Windows. We compared using the linear model of direct costs and unit costs of anaesthesiological services from the Costs List of the Republican Health-care Insurance. Results. Direct costs showed 40% of costs were spent on salaries, (32% on drugs and supplies, and 28% on other costs, such as analyses and equipment. The correlation of the direct costs of anaestesiological services showed a linear correlation with the unit costs of the Republican Healthcare Insurance. Conclusion. During surgery, costs of anaesthesia would increase by 10% the surgical treatment cost of patients. Regarding the actual costs of drugs and supplies, we do not see any possibility of costs reduction. Fixed elements of direct costs provide the possibility of rationalization of resources in anaesthesia.

  19. Popularity at Minimum Cost

    2010-01-01

    We consider an extension of the {\\em popular matching} problem in this paper. The input to the popular matching problem is a bipartite graph G = (A U B,E), where A is a set of people, B is a set of items, and each person a belonging to A ranks a subset of items in an order of preference, with ties allowed. The popular matching problem seeks to compute a matching M* between people and items such that there is no matching M where more people are happier with M than with M*. Such a matching M* is called a popular matching. However, there are simple instances where no popular matching exists. Here we consider the following natural extension to the above problem: associated with each item b belonging to B is a non-negative price cost(b), that is, for any item b, new copies of b can be added to the input graph by paying an amount of cost(b) per copy. When G does not admit a popular matching, the problem is to "augment" G at minimum cost such that the new graph admits a popular matching. We show that this problem is...

    The current study examined costs experienced by victims of completed rape (n=49) and attempted sexual assault (n=91) using quantitative analyses of 13 domains: health, self-esteem, self-perceived attractiveness, self-perceived mate value, family relationships,work life, social life, social reputation, sexual reputation, desire to have sex, frequency of sex, enjoyment of sex, and long-term, committed relationships. Women also provided descriptive accounts of their experiences, and we used these to illustrate the costs in the victims' own words.Compared to victims of an attempted sexual assault, victims of a completed rape reported significantly more negative outcomes in 11 of the 13 domains. The most negatively affected domains were self-esteem, sexual reputation, frequency of sex, desire to have sex, and self-perceived mate value. Although victims of rape experienced more negative effects than victims of attempted sexual assault,both groups of victims reported negative effects in every domain.Discussion focuses on the implications of the differing degrees and patterns of the costs of attempted and completed sexual victimization.

    We analyze a photonic integrated circuit (PIC) platform comprised of a crystalline AlxGa1-xN optical guiding layer on an AlN substrate for the ultraviolet to visible (UV-vis) wavelength range. An Al composition of x~0.65 provides a refractive index difference of ~0.1 between AlxGa1-xN and AlN, and a small lattice mismatch (xGa1-xN/AlN interface. This small refractive index difference is beneficial at shorter wavelengths to avoid extra-small waveguide dimensions. The platform enables compact waveguides and bends with high field confinement in the wavelength range from 700 nm down to 300 nm (and potentially lower) with waveguide cross-section dimensions comparable to those used for telecom PICs such as silicon and silicon nitride waveguides, allowing for well-established optical lithography. This platform can potentially enable cost-effective, manufacturable, monolithic UV-vis photonic integrated circuits.

    Two porosity models of porous Al alloys with different pore types (ball and polygon shape) were established. The experimental results coincide well with theoretical computations. The porosity of Al alloys (Prc) consists of three parts, porosity caused by preform particles (Prp), additional porosity (Pra), and porosity caused by solidification shrinkage (Prs). Prp is the main part of Prc while Pra is the key for fabricating porous Al alloys successfully in spite of its little contribution to Prc.

    Acid mine drainage (AMD) severely impacts the water chemistry of a receiving resource, changing the occurrence, speciation and toxicity of metals such as Aluminium (Al). The toxicity of Al is determined by its speciation represented by the labile monomer Al fraction or Al(3+). The purpose of the study was to combine fractionation and Visual MINTEQ speciation to calculate the effect of AMD altered water chemistry on Al speciation and Al(3+) concentration. Water in rivers impacted by AMD presented with monomeric Al (Almon) concentrations between 0.35 and 15.37mgL(-)(1) which existed almost exclusively in the toxic labile form (98%). For the reference site, Almon was less than 2% (10μgL(-1)), suggesting significantly lower Al toxicity. Principal component analysis plots illustrated that labile Al was directly related to the total Al and iron concentrations and strongly influenced by parameters such as pH, electrical conductivity, sulphate and dissolved organic carbon. Visual MINTEQ modelling was used to determine the primary Al species distribution. The dominant form of Al in AMD impacted water was AlSO4(+), which increased proportionally with the sulphate and Al(3+) concentration. Heavily impacted areas, presented with an average of 1mgmL(-)(1) Al(3+), which poses a potential human health risk. A novel centrifugal ultrafiltration method was investigated as an alternative to determining Almon to simplify the speciation of Al. Monomeric and centrifugal ultrafiltrated (<10kD) Al fractions were significantly similar (p=0.74), suggesting that ultrafiltration may present a time, energy and cost saving alternative to organic extraction of Almon.

    Full Text Available In this paper, it is argued for a particular approach —progressive democratic social action— to the solution of the social problems associated with our technological society. The case is made through a process of elimination, showing how this approach has better prospects than others: technology assessment, the proposal of ethical rules as limits on technology, or the political control of technology. The author argues for a social activism focused on specific cases and local settings as the most adequate way of dealing with technosocial problems.

    En este artículo se defiende la «acción social democrática progresista» como método idóneo para enfrentarse a los problemas relacionados con nuestra sociedad tecnológica. Se repasan otros enfoques ensayados, como la evaluación de tecnologías, la propuesta de reglas éticas para la ciencia y la tecnología, o el control político de la tecnología. El autor argumenta a favor del activismo social centrado en casos concretos y emplazamientos locales como la forma más eficaz de resolver los problemas tecnosociales.

    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.

    2015-01-01

    Determining the cost-effectiveness of healthcare interventions is key to the decision-making process in healthcare. Cost comparisons are used to demonstrate the economic value of treatment options, to evaluate the impact on the insurer budget, and are often used as a key criterion in treatment comparison and comparative effectiveness; however, little guidance is available to researchers for establishing the costing of clinical events and resource utilization. Different costing methods exist, and the choice of underlying assumptions appears to have a significant impact on the results of the costing analysis. This editorial describes the importance of the choice of the costing technique and it's potential impact on the relative cost of treatment options. This editorial also calls for a more efficient approach to healthcare intervention costing in order to ensure the use of consistent costing in the decision-making process.

    Interfaces formed by Al-Al thermocompression bonding were studied by the transmission electron microscopy. Si wafer pairs having patterned bonding frames were bonded using Al films deposited on Si or SiO{sub 2} as intermediate bonding media. A bond force of 36 or 60 kN at bonding temperatures ranging from 400–550 °C was applied for a duration of 60 min. Differences in the bonded interfaces of 200 μm wide sealing frames were investigated. It was observed that the interface had voids for bonding with 36 kN at 400 °C for Al deposited both on Si and on SiO{sub 2}. However, the dicing yield was 33% for Al on Si and 98% for Al on SiO{sub 2}, attesting for the higher quality of the latter bonds. Both a bond force of 60 kN applied at 400 °C and a bond force of 36 kN applied at 550 °C resulted in completely bonded frames with dicing yields of, respectively, 100% and 96%. A high density of long dislocations in the Al grains was observed for the 60 kN case, while the higher temperature resulted in grain boundary rotation away from the original Al-Al interface towards more stable configurations. Possible bonding mechanisms and reasons for the large difference in bonding quality of the Al films deposited on Si or SiO{sub 2} are discussed.

    2011-01-01

    What should parents do when they detect indications of more predators nearby that might eat their babies? This scenario is commonly faced by parents in the wild, and the consequences are important. The number of offspring that organisms produce has a major influence on fitness and, when averaged across a population, affects whether this population will increase or decrease. Offspring production thus has critical implications for evolution via fitness, and ecology and conservation via demography. On page 1398 of this issue, Zanette et al. (1) show that the fear of predation can, by itself, strongly affect the number of offspring produced over an annual cycle by song sparrows (see the figure).

    Successful commercialization of fusion energy requires economic viability as well as technical and scientific feasibility. To assess economic viability, we have conducted a pre-conceptual level evaluation of LIFE economics. Unit costs are estimated from a combination of bottom-up costs estimates, working with representative vendors, and scaled results from previous studies of fission and fusion plants. An integrated process model of a LIFE power plant was developed to integrate and optimize unit costs and calculate top level metrics such as cost of electricity and power plant capital cost. The scope of this activity was the entire power plant site. Separately, a development program to deliver the required specialized equipment has been assembled. Results show that LIFE power plant cost of electricity and plant capital cost compare favorably to estimates for new-build LWR's, coal and gas - particularly if indicative costs of carbon capture and sequestration are accounted for.

    2015-04-01

    Breaches in data security have become commonplace in health care, making IT security a necessary cost for healthcare organizations. Organizations that do not invest proactively in IT security face a significant risk of incurring much greater costs from incidents involving compromised data security. Direct costs of security breaches include the costs of discovery, response, investigation, and notification and also can include state or federal penalties and costs of compliance with corrective action plans and resolution agreements. Hidden costs can include damage to brand, loss of consumer confidence, reduced HCAHPS scores, and--by extension--reduced value-based purchasing payments.

    Elevated-temperature powder metallurgy (P/M) aluminum alloys are being developed to replace titanium aircraft structure materials for operation in the 300-600 F temperature range. Typical mechanical properties of P/M Al-Fe-Ce and Al-Fe-V-Si alloys are superior to those of conventional materials, and cost savings of 50 to 70 percent have been projected for these alloys which can be fabricated and processed using methods similar to those used in the production of conventional aluminum. 5 references.

    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.

    Full Text Available In the present study, we have investigated the effects of illumination intensity on the optical and electrical characteristics of the Al/CdFe2O4/p-Si/Al photodiode. A thin film of CdFe2O4 was fabricated using the sol-gel spin coating method that allows good thickness control and low-cost manufacturing as compared to alternative techniques. The current-voltage (I-V of the Al/CdFe2O4/p-Si/Al photodiode was measured in the dark and under different illumination intensities. The photocurrent increased with higher luminous intensity and its sensitivity has a strong dependence on the reverse bias rising from 1.08⁎10-7 A under dark conditions to 6.11⁎10-4 A at 100 mW/cm2 of illumination. The parameters of the photodiode such as ideality factor and barrier height were calculated using the thermionic emission model. The ideality factor of the Al/CdFe2O4/p-Si/Al photodiode was found to be 4.4. The barrier height was found to be 0.88 eV. The capacitance-voltage (C-V characteristics measured at different frequencies have strongly varied with frequency, decreasing with frequency. Consequently, the resulting interface density (Dit value of the Al/CdFe2O4/p-Si/Al photodiode also decreased with higher frequency. Similarly, the fitted series resistance of the Al/CdFe2O4/p-Si/Al photodiode has declined with higher frequency.

  11. Cast Aluminum Alloys for High Temperature Applications Using Nanoparticles Al2O3 and Al3-X Compounds (X = Ti, V, Zr)

    2009-01-01

    In this paper, the effect of nanoparticles Al2O3 and Al3-X compounds (X = Ti, V, Zr) on the improvement of mechanical properties of aluminum alloys for elevated temperature applications is presented. These nanoparticles were selected based on their low cost, chemical stability and low diffusions rates in aluminum at high temperatures. The strengthening mechanism at high temperature for aluminum alloy is based on the mechanical blocking of dislocation movements by these nanoparticles. For Al2O3 nanoparticles, the test samples were prepared from special Al2O3 preforms, which were produced using ceramic injection molding process and then pressure infiltrated by molten aluminum. In another method, Al2O3 nanoparticles can also be homogeneously mixed with fine aluminum powder and consolidated into test samples through hot pressing and sintering. With the Al3-X nanoparticles, the test samples are produced as precipitates from in-situ reactions with molten aluminum using conventional permanent mold or die casting techniques. It is found that cast aluminum alloy using nanoparticles Al3-X is the most cost effective method to produce high strength aluminum alloys for high temperature applications in comparison to nanoparticles Al2O3. Furthermore, significant mechanical properties retention in high temperature environment could be achieved with Al3-X nanoparticles, resulting in tensile strength of nearly 3 times higher than most 300- series conventional cast aluminum alloys tested at 600 F.

    The γ -ray emission associated with the radioactive decay of 26Al is one of the key pieces of observational evidence indicating stellar nucleosynthesis is an ongoing process in our Galaxy, and it was the first such radioactivity to be detected. Despite numerous efforts in stellar modeling, observation, nuclear theory, and nuclear experiment over the past four decades, the precise sites and origin of Galactic ^{26} Al remain elusive. We explore the present experimental knowledge concerning the destruction of ^{26} Al in massive stars. The precise stellar rates of neutron-induced reactions on ^{26} Al, such as (n,p) and (n, α , have among the largest impacts on the total ^{26} Al yield. Meanwhile, reactions involving the short-lived isomeric state of ^{26} Al such as radiative proton capture are highly-uncertain at present. Although we presented on-going experimental work from n_TOF at CERN with an ^{26} Al target, the present proceeding focuses only on the ^{26} Al isomeric radioactive beam production aspect and the first experimental results at CRIB.

    To date, there has been no standard method or tool to analyze the installed and operational costs for distributed wind turbine systems. This report describes the development of a classification system, or taxonomy, for distributed wind turbine project costs. The taxonomy establishes a framework to help collect, sort, and compare distributed wind cost data that mirrors how the industry categorizes information. The taxonomy organizes costs so they can be aggregated from installers, developers, vendors, and other sources without losing cost details. Developing a peer-reviewed taxonomy is valuable to industry stakeholders because a common understanding the details of distributed wind turbine costs and balance of station costs is a first step to identifying potential high-value cost reduction opportunities. Addressing cost reduction potential can help increase distributed wind's competitiveness and propel the U.S. distributed wind industry forward. The taxonomy can also be used to perform cost comparisons between technologies and track trends for distributed wind industry costs in the future. As an initial application and piloting of the taxonomy, preliminary cost data were collected for projects of different sizes and from different regions across the contiguous United States. Following the methods described in this report, these data are placed into the established cost categories.

    Metal Sm has been widely used in making Al-Sm magnet alloy materials. Conventional distillation technology to produce Sm has the disadvantages of low productivity, high costs, and pollution generation. The objective of this study was to develop a molten salt electrolyte system to produce Al-Sm alloy directly, with focus on the electrical conductivity and optimal operating conditions to minimize the energy consumption. The continuously varying cell constant (CVCC) technique was used to measure the conductivity for the Na3AlF6-AlF3-LiF-MgF2-Al2O3-Sm2O3 electrolysis medium in the temperature range from 905 to 1055°C. The temperature ( t) and the addition of Al2O3 ( W(Al2O3)), Sm2O3 ( W(Sm2O3)), and a combination of Al2O3 and Sm2O3 into the basic fluoride system were examined with respect to their effects on the conductivity ( κ) and activation energy. The experimental results showed that the molten electrolyte conductivity increases with increasing temperature ( t) and decreases with the addition of Al2O3 or Sm2O3 or both. We concluded that the optimal operation conditions for Al-Sm intermediate alloy production in the Na3AlF6-AlF3-LiF-MgF2-Al2O3-Sm2O3 system are W(Al2O3) + W(Sm2O3) = 3wt%, W(Al2O3): W(Sm2O3) = 7:3, and a temperature of 965 to 995°C, which results in satisfactory conductivity, low fluoride evaporation losses, and low energy consumption.

    Full Text Available Solar energy the most efficient, eco-friendly and abundantly available energy source in the nature. It can be converted into electrical energy in cost effective manner. In recent years, the interest in solar energy has risen due to surging oil prices and environmental concern. In many remote or underdeveloped areas, direct access to an electric grid is impossible and a photovoltaic inverter system would make life much simpler and more convenient. With this in mind, it is aimed to design, build, and test a solar panel inverter. This inverter system could be used as backup power during outages, battery charging, or for typical household applications. The main components of this solar system are solar cell, dc to dc boost converters, and inverter. Sine wave push pull inverter topology is used for inverter. In this topology only two MOSFETs are used and isolation requirement between control circuit and power circuit is also less which helps to decrease the cost of solar inverter.

    2000-01-01

    Managed care organizations (MCOs) face an uncertain future. While consolidation and price competition have expanded their market share, health care expenditures are expected to rise in the near future, and the cost containment premise--and promise--of MCOs is being threatened by mixed blessing and nonsupportive stakeholders. To shed light on MCOs' situation, we discuss four drivers for change in health management in the U.S.: technology, regulation, consumerism, and demographics. Using those four drivers, we then assess the various stakeholders in the industry through a competitive analysis and a stakeholder analysis. These analyses suggest that the munificence of the MCO business environment has significantly declined, especially among supplier and buyer stakeholders. Hence, MCOs cannot continue to manage health care costs alone as this will no longer generate sufficient support among buyer and supplier stakeholders. Instead, MCOs must tackle five critical health care issues by working closely with other stakeholders and also by learning what they can from innovative health care initiatives both inside and outside the United States.

    Full Text Available This article discusses the significance of the achievements of the COST 271 Action on science and technology for space weather and telecommunications in Europe and the world. The Action's work has impacted national and international projects and the decision processes. The key words encompassed in the title of COST 271 are «space weather». But as the reader of this Final Report will appreciate, many more topics were addressed during the Action by the large team of workers from a wide range of countries and organisations than this wording would suggest. Relevant to the performance of telecommunication systems that rely on the presence of the ionosphere for propagation support, or that are affected by transmission through it, there have been investigations among other items of solar and magnetosphere disturbances on the ionosphere, satellite and ground-based measurements of the ionosphere, assembly of near-real-time databases of ionosphere information on the Web, studies of planetary and gravity waves in the ionosphere, ionosphere modelling, mapping and forecasting, long-term changes, ray-path deviations in the presence of irregularities, channel-scattering functions, and scintillations on Earth-space paths. The impact of all this work on the outside communities can be considered within three broad headings as follows.

    2012-03-01

    Explaining the evolution of sex is challenging for biologists. A 'twofold cost' compared with asexual reproduction is often quoted. If a cost of this magnitude exists, the benefits of sex must be large for it to have evolved and be maintained. Focusing on benefits can be misleading, as this sidelines important questions about the cost of sex: what is the source of the twofold cost: males, genome dilution or both? Does the cost deviate from twofold? What other factors make sex costly? How should the costs of sex be empirically measured? The total cost of sex and how it varies in different contexts must be known to determine the benefits needed to account for the origin and maintenance of sex. Copyright © 2011 Elsevier Ltd.

    Full Text Available The main purpose of this research is to present a way for organizing the accountancy under the conditions of applying the method of standard costs, such that to allow both the registration of standard and effective costs and the separate registration of the deviations from standard costs. Making some pertinent and performance decisions is mainly influenced by the quality of the information provided to managers and by the promptitude they are sent. This desiderate is not possible if using classical methods for calculating costs, reason for which it is mandatory to organize and implement a managerial accountancy, based on using a modern method, namely the method of standard costs. The main implications of this method consist of establishing a pertinent cost, orientated towards the entity management, regardless the activity domain where it is implemented. The carried out study concerns only one of the phases performed for applying the method of standard cost, respectively the organization of the standard costs accountancy.

    The question of wind integration cost has received much attention in the past several years. The methodological challenges to calculating integration costs are discussed in this paper. There are other sources of integration cost unrelated to wind energy. A performance-based approach would be technology neutral, and would provide price signals for all technology types. However, it is difficult to correctly formulate such an approach. Determining what is and is not an integration cost is challenging. Another problem is the allocation of system costs to one source. Because of significant nonlinearities, this can prove to be impossible to determine in an accurate and objective way.

    The aim of this study was (a) to estimate the cost of dementia in Switzerland, (b) to compare the average annual cost for people with dementia who live at home and those living in an institution and (c) to analyse how the average cost per person with dementia who lives at home increases with the severity of dementia. This prevalence-based cost-of-illness study from a societal perspective combined top-down and bottom-up approaches and included both direct and indirect costs of dementia. Cost estimations were based on Swiss national statistics and surveys, as well as international reviews and expert interviews. The total annual cost of dementia amounted up to CHF 6.3 billion for the year 2007. Together, institutional and informal care accounted for over 90% of the cost. The average annual cost was estimated at CHF 55'300 per person with dementia who lives at home and at CHF 68'900 per person who lives in an institution. The cost per person living at home with severe dementia was nearly five times the cost per person with mild dementia. The present study indicates that dementia imposes a considerable economic burden on Swiss society. The cost of dementia is dominated by the costs of care. Diagnosis and treatment related costs are minor. These findings are consistent with contemporary international studies on the subject. The contribution of informal caregivers is substantial since they account for 44% of the total cost of dementia (based on market cost valuation). Given demographic developments in Switzerland, healthcare decision making should have an interest in securing this potential for the future.

  11. Reliability and cost considerations for launch vehicle avionics

    Science.gov (United States)

    Wensley, John H.; Uhrich, Don D.

    The optimum redundancy for an avionics processor can be determined from cost and reliability considerations. The use and expense of redundant architectures are examined, along with the cost and advantages of using space-qualified parts. The advanced launch system (ALS) vehicle model was used for the comparisons. Avionics redundancy models included duplex, triple modular redundancy, and quad systems. Processors were modeled as simplex, dual self-checking pairs, or triplex checking. Cost factors were those which result in the cost per launched vehicle. These included cost of launch equipment, cost of scrubbing a launch, failure investigation, repair, and the cost of money due to schedule delays. The primary conclusion reached was that the use of redundancy to achieve fault tolerance is required for higher value missions. The use of less-highly qualified parts can lower costs for less expensive payloads, but will require a culture change to allow launching with known faults. The need for greater emphasis on determination of coverage for fault-tolerant systems was demonstrated.

  14. Cost Overruns and Cost Estimation in the North Sea

    Energy Technology Data Exchange (ETDEWEB)

    Emhjellen, Magne; Emhjellen, Kjetil; Osmundsen, Petter

    2001-10-01

    Recently, a Norwegian government report on the cost overruns of projects in the North Sea was presented (NOU 1999:11). It concluded that there was a 25% increase in development costs from project sanction (POD, Plan for Operation and Development) to last CCE (Capital Cost Estimate) for the 11 oil field projects investigated. Many reasons like unclear project assumptions in early phase, optimistic interpolation of previous project assumptions, too optimistic estimates, and underestimation of uncertainty were given as reasons for overruns. In this article we highlight the possibility that the cost overruns are not necessarily all due to the reasons given, but also to an error in the estimation and reporting of the capital expenditure cost (CAPEX). Usually the CAPEX is given by a single cost figure, with some indication of its probability distribution. The oil companies report, and are required to do so by government authorities, the estimated 50/50 (median) cost estimate instead of the estimated expected value cost estimate. We demonstrate how the practice of using a 50/50 (median) CAPEX estimate for the 11 projects when the cost uncertainty distributions are asymmetric, may explain at least part of the ''overruns''. Hence, we advocate changing the practice of using 50/50 cost estimates instead of expected value cost estimates for project management and decision purposes. (author)

    Full Text Available Switching cost is defined as possible costs that customers may encounter when they want to change the firm they buy service, and an important subject in terms of accounting services. Particularly, small business entrepreneurs’ not having knowledge about accounting procedures, and sharing private information with accounting firms make switching costs more important for accounting services. Thus, the aim of this study is to investigate the concept of switching costs (relational cost, procedural cost and financial cost, its determinants (perceived service quality, service importance, and service failures, and consequences (re-purchasing, and recommen ding to others. Theresearch was conducted on small business entrepreneurs in down-town of Balıkesir in Turkey. Total 405 small business entrepreneur owners were interviewed. According to results of the study, perceived service quality positively affects all dimensions of switching costs, significance of service positively affects procedural and relational costs, and service failures negatively affect procedural and relational costs. The results showed that while procedural and relational costs positively affect re-purchasing and recommending to others variables, financial cost did not have any effect on these variables.

    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.

    Different to Kurzban et al., we conceptualize the experience of mental effort as the subjective costs of goal pursuit (i.e., the amount of invested resources relative to the amount of available resources). Rather than being an output of computations that compare costs and benefits of the target and competing goals, effort enters these computations as an input.

    This study examined social processes of support, goal direction, provision of role models, and involvement in rewarding activities to explain benefits of participating in Al-Anon, a 12-step mutual-help program for people concerned about another person's substance use. Newcomers to Al-Anon were studied at baseline and 6 months later, at which time they were identified as having either sustained attendance or dropped out. Among both newcomers and established Al-Anon members ("old-timers"), we also used number of Al-Anon meetings attended during follow-up to indicate extent of participation. Social processes significantly mediated newcomers' sustained attendance status versus dropped out and outcomes of Al-Anon in the areas of life context (e.g., better quality of life, better able to handle problems due to the drinker), improved positive symptoms (e.g., higher self-esteem, more hopeful), and decreased negative symptoms (e.g., less abuse, less depressed). Social processes also significantly mediated newcomers' number of meetings attended and outcomes. However, among old-timers, Al-Anon attendance was not associated with outcomes, so the potential mediating role of social processes could not be examined, but social processes were associated with outcomes. Findings add to the growing body of work identifying mechanisms by which 12-step groups are effective, by showing that bonding, goal direction, and access to peers in recovery and rewarding pursuits help to explain associations between sustained Al-Anon participation among newcomers and improvements on key concerns of Al-Anon attendees. Al-Anon is free of charge and widely available, making it a potentially cost-effective public health resource for help alleviating negative consequences of concern about another's addiction.

  7. The Costs of Knowledge

    2008-01-01

    Acquiring knowledge-genuinely learning something new-requires the consent and commitment of the person you're trying to learn from. In contrast to information, which can usually be effectively transmitted in a document or diagram, knowledge comes from explaining, clarifying, questioning, and sometimes actually working together. Getting this kind of attention and commitment often involves some form of negotiation, since even the most generous person's time and energy are limited. Few experts sit around waiting to share their knowledge with strangers or casual acquaintances. In reasonably collaborative enterprises- I think NASA is one-this sort of negotiation isn't too onerous. People want to help each other and share what they know, so the "cost" of acquiring knowledge is relatively low. In many organizations (and many communities and countries), however, there are considerable costs associated with this activity, and many situations in which negotiations fail. The greatest knowledge cost is in and adopting knowledge to one's own use. Sometimes this means formally organizing what one learns in writing. Sometimes it means just taking time to reflect on someone else's thoughts and experiences-thinking about knowledge that is not exactly what you need but can lead you to develop ideas that will be useful. A long, discursive conversation, with all the back-and-forth that defines conversation, can be a mechanism of knowledge exchange. I have seen many participants at NASA APPEL Masters Forums talking, reflecting, and thinking-adapting what they are hearing to their own needs. Knowledge transfer is not a simple proposition. An enormous amount of information flows through the world every day, but knowledge is local, contextual, and "stickyn-that is, it takes real effort to move it from one place to another. There is no way around this. To really learn a subject, you have to work at it, you have to pay your "knowledge dues." So while, thanks to advances in technology

    Intensive care unit (ICU) costs account for a great part of a hospital's expenses. The objective of the present study was to measure the patient-specific cost of ICU treatment, to identify the most important cost drivers in ICU and to examine the role of various contributing factors in cost configuration. A retrospective cost analysis of all ICU patients who were admitted during 2011 in a Greek General, seven-bed ICU and stayed for at least 24hours was performed, by applying bottom-up analysis. Data collected included demographics and the exact cost of every single material used for patients' care. Prices were yielded from the hospital's purchasing costs and from the national price list of the imaging and laboratory tests, which was provided by the Ministry of Health. A total of 138 patients were included. Variable cost per ICU day was €573.18. A substantial cost variation was found in the total costs obtained for individual patients (median: €3443, range: €243.70-€116,355). Medicines were responsible for more than half of the cost and antibiotics accounted for the largest part of it, followed by blood products and cardiovascular drugs. Medical cause of admission, severe illness and increased length of stay, mechanical ventilation and dialysis were the factors associated with cost escalation. ICU variable cost is patient-specific, varies according to each patient's needs and is influenced by several factors. The exact estimation of variable cost is a pre-requisite in order to control ICU expenses.

    There is an interesting experimental result (S. Korobtsev, D. Medvedev et al , ISPC 13,1997, vol.2, p. 755. ) for low cost ozone generation (7-8 eV/molec in air) in streamer with dominant energy consumption in streamer channel (where molecular vibrations are excited). For explanation we considered the effect of vibrational pumping saturation, when vibrational energy was increased (due to the super-elastic processes) and the change of electron cross-sections due to vibrational excitation, which could also lead to efficiency growth. Boltzmann equation solution showed that both effects required too large energy consumption in discharge (>0.7 eV/mole). Thus we went to conclusion, that some direct energy transfer from vibrational degrees of freedom to electronic degrees should take place. One of the possible new mechanisms is the reaction: N2 (v)+N2 (v)=N2 (A)+N_2. Our numerical model of vibrational kinetic in air with this reaction showed that dependence of ozone generation cost upon energy consumption in streamer channel had a minimum with the value of the cost about 8-10 eV/molec.

    Full Text Available The Danish Ministry of Culture has funded a project to set up a model for costing preservation of digital materials held by national cultural heritage institutions. The overall objective of the project was to increase cost effectiveness of digital preservation activities and to provide a basis for comparing and estimating future cost requirements for digital preservation. In this study we describe an activity-based costing methodology for digital preservation based on the Open Archice Information System (OAIS Reference Model. Within this framework, which we denote the Cost Model for Digital Preservation (CMDP, the focus is on costing the functional entity Preservation Planning from the OAIS and digital migration activities. In order to estimate these costs we have identified cost-critical activities by analysing the functions in the OAIS model and the flows between them. The analysis has been supplemented with findings from the literature, and our own knowledge and experience. The identified cost-critical activities have subsequently been deconstructed into measurable components, cost dependencies have been examined, and the resulting equations expressed in a spreadsheet. Currently the model can calculate the cost of different migration scenarios for a series of preservation formats for text, images, sound, video, geodata, and spreadsheets. In order to verify the model it has been tested on cost data from two different migration projects at the Danish National Archives (DNA. The study found that the OAIS model provides a sound overall framework for the cost breakdown, but that some functions need additional detailing in order to cost activities accurately. Running the two sets of empirical data showed among other things that the model underestimates the cost of manpower-intensive migration projects, while it reinstates an often underestimated cost, which is the cost of developing migration software. The model has proven useful for estimating the

    Recent resource assessments conducted by the United States Department of Energy have identified significant opportunities for expanding hydropower generation through the addition of power to non-powered dams and on undeveloped stream-reaches. Additional interest exists in the powering of existing water resource infrastructure such as conduits and canals, upgrading and expanding existing hydropower facilities, and the construction new pumped storage hydropower. Understanding the potential future role of these hydropower resources in the nation’s energy system requires an assessment of the environmental and techno-economic issues associated with expanding hydropower generation. To facilitate these assessments, this report seeks to fill the current gaps in publically available hydropower cost-estimating tools that can support the national-scale evaluation of hydropower resources.

    This fact sheet is an overview of the systems integration subprogram at the U.S. Department of Energy SunShot Initiative. Soft costs can vary significantly as a result of a fragmented energy marketplace. In the U.S., there are 18,000 jurisdictions and 3,000 utilities with different rules and regulations for how to go solar. The same solar equipment may vary widely in its final installation price due to process and market variations across jurisdictions, creating barriers to rapid industry growth. SunShot supports the development of innovative solutions that enable communities to build their local economies and establish clean energy initiatives that meet their needs, while at the same time creating sustainable solar market conditions.

  14. Energy cost and optimisation in breath-hold diving.

    Trassinelli, M

    2016-05-07

    We present a new model for calculating locomotion costs in breath-hold divers. Starting from basic mechanics principles, we calculate the work that the diver must provide through propulsion to counterbalance the action of drag, the buoyant force and weight during immersion. Compared to those in previous studies, the model presented here accurately analyses breath-hold divers which alternate active swimming with prolonged glides during the dive (as is the case in mammals). The energy cost of the dive is strongly dependent on these prolonged gliding phases. Here we investigate the length and impacts on energy cost of these glides with respect to the diver characteristics, and compare them with those observed in different breath-hold diving species. Taking into account the basal metabolic rate and chemical energy to propulsion transformation efficiency, we calculate optimal swim velocity and the corresponding total energy cost (including metabolic rate) and compare them with observations. Energy cost is minimised when the diver passes through neutral buoyancy conditions during the dive. This generally implies the presence of prolonged gliding phases in both ascent and descent, where the buoyancy (varying with depth) is best used against the drag, reducing energy cost. This is in agreement with past results (Miller et al., 2012; Sato et al., 2013) where, when the buoyant force is considered constant during the dive, the energy cost was minimised for neutral buoyancy. In particular, our model confirms the good physical adaption of dolphins for diving, compared to other breath-hold diving species which are mostly positively buoyant (penguins for example). The presence of prolonged glides implies a non-trivial dependency of optimal speed on maximal depth of the dive. This extends previous findings (Sato et al., 2010; Watanabe et al., 2011) which found no dependency of optimal speed on dive depth for particular conditions. The energy cost of the dive can be further

    Aluminium laurate [Al(OOCC11H23)3] was synthesized as a surfactant, which can dissolve in micellar solution of a zwitterionic surfactant, tetradecycldimethylamine oxide (C14DMAO). The phase behavior of the mixtures of Al(OOCC11H23)3 and C14DMAO in water was studied and birefringent Lα-phase was observed. The birefringent Lα-phase consists of vesicles that were demonstrated by Polarizer and Transmission Electron Microscope (TEM) micrographs. Al3+-coordinated vesicles could be used as templating-precursor, providing a vesicle-route for preparation of inorganic nanoscale particles.

  16. Heterogeneous nucleation of solid Al from the melt by TiB2 and Al3Ti: An ab initio molecular dynamics study

    KAUST Repository

    Wang, Junsheng

    2010-11-16

    The nucleation of solid Al from the melt by TiB2 is well established and is believed to involve the formation of Al3Ti. Since the atomic-scale mechanisms involved are not fully understood, we look to computer simulation to provide insight. As there is an absence of suitable potentials for all of this complex system we have performed large-scale density-functional-theory molecular dynamics simulations of the nucleation of solid Al from the melt on TiB2 and Al3Ti substrates at undercoolings of around 2 K. Using periodic boundary conditions, we find limited ordering and no signs of incipient growth in the liquid Al close to the B-terminated surface of TiB2. By contrast, we see fcc-like ordering near the Ti-terminated surface, with growth being frustrated by the lattice mismatch between bulk Al and the TiB2 substrate. The Al interatomic distances at the Ti-terminated surface are similar to distances found in Al3Ti; we suggest that the layer encasing TiB2 observed experimentally may be strained Al on a Ti-terminated surface rather than Al3Ti. For the Al3Ti substrate, fcc-like structures are observed on both sides which extend rapidly into the melt. Periodic boundaries introduce unphysical stresses which we removed by introducing a vacuum region to separate the liquid from the solid at one of the interfaces. We see ordering in the Al on both the B-terminated (0001) surface of TiB2, and on Al3Ti(112), with the ordering able to be stronger on the Al3Ti substrate. However, we cannot draw strong conclusions as these simulations need more time to allow long-ranged fluctuations in the liquid Al to dampen out. The huge computational cost restricted the range and duration of simulations that was possible.

    This chapter investigates the concept of the ‘hidden costs’ of offshoring, i.e. unexpected offshoring costs exceeding the initially expected costs. Due to the highly undefined nature of these costs, we position our analysis towards the strategic responses of firms’ realisation of hidden costs....... In this regard, we argue that a major response to the hidden costs of offshoring is the identification and utilisation of strategic mechanisms in the organisational design to eventually achieving system integration in a globally dispersed and disaggregated organisation. This is heavily moderated by a learning...

    The immunization status of children is improved by interventions that increase community demand for compulsory and non-compulsory vaccines, one of the most important interventions related to immunization providers. The aim of this study is to evaluate the activities of immunization providers in terms of activities time and cost, to calculate the immunization doses cost, and to determine the immunization dose errors cost. Time-motion and cost analysis study design was used. Five public health clinics in Mosul-Iraq participated in the study. Fifty (50) vaccine doses were required to estimate activities time and cost. Micro-costing method was used; time and cost data were collected for each immunization-related activity performed by the clinic staff. A stopwatch was used to measure the duration of activity interactions between the parents and clinic staff. The immunization service cost was calculated by multiplying the average salary/min by activity time per minute. 528 immunization cards of Iraqi children were scanned to determine the number and the cost of immunization doses errors (extraimmunization doses and invalid doses). The average time for child registration was 6.7 min per each immunization dose, and the physician spent more than 10 min per dose. Nurses needed more than 5 min to complete child vaccination. The total cost of immunization activities was 1.67 US$ per each immunization dose. Measles vaccine (fifth dose) has a lower price (0.42 US$) than all other immunization doses. The cost of a total of 288 invalid doses was 744.55 US$ and the cost of a total of 195 extra immunization doses was 503.85 US$. The time spent on physicians' activities was longer than that spent on registrars' and nurses' activities. Physician total cost was higher than registrar cost and nurse cost. The total immunization cost will increase by about 13.3% owing to dose errors.

  3. Costing blood products and services.

    Wallace, E L

    1991-05-01

    At present, blood centers and transfusion services have limited alternatives for offsetting the ever-rising costs of health care inputs. In the face of current revenue constraints, cost reduction or cost containment through efficiency improvements or service reduction is the principal available means. Such methods ought to be pursued vigorously by blood bankers with the aid of well-designed costing and other physical measurements systems. Experience indicates, however, that blood bankers, in their attempts to reduce or contain costs, are likely to place undue reliance on cost accounting systems as the means of capturing sought-for benefits. Management must learn enough about methods of costing to judge directly the uses and limitations of the information produced. Such understanding begins with recognition that all costs and cost comparisons should be specific to the purpose for which they are developed. No costing procedure is capable of producing measures generally applicable to all management decisions. A measure relevant to a planning decision is unlikely to be appropriate for performance evaluation. Useful comparisons among sets of organizations of costs, or of measures of physical inputs and outputs, require assurance that the methods of measurement employed are the same and that the sets of organizations from which the measures are drawn are reasonably comparable.

  4. Realistic costs of carbon capture

    2009-07-01

    There is a growing interest in carbon capture and storage (CCS) as a means of reducing carbon dioxide (CO2) emissions. However there are substantial uncertainties about the costs of CCS. Costs for pre-combustion capture with compression (i.e. excluding costs of transport and storage and any revenue from EOR associated with storage) are examined in this discussion paper for First-of-a-Kind (FOAK) plant and for more mature technologies, or Nth-of-a-Kind plant (NOAK). For FOAK plant using solid fuels the levelised cost of electricity on a 2008 basis is approximately 10 cents/kWh higher with capture than for conventional plants (with a range of 8-12 cents/kWh). Costs of abatement are found typically to be approximately US$150/tCO2 avoided (with a range of US$120-180/tCO2 avoided). For NOAK plants the additional cost of electricity with capture is approximately 2-5 cents/kWh, with costs of the range of US$35-70/tCO2 avoided. Costs of abatement with carbon capture for other fuels and technologies are also estimated for NOAK plants. The costs of abatement are calculated with reference to conventional SCPC plant for both emissions and costs of electricity. Estimates for both FOAK and NOAK are mainly based on cost data from 2008, which was at the end of a period of sustained escalation in the costs of power generation plant and other large capital projects. There are now indications of costs falling from these levels. This may reduce the costs of abatement and costs presented here may be 'peak of the market' estimates. If general cost levels return, for example, to those prevailing in 2005 to 2006 (by which time significant cost escalation had already occurred from previous levels), then costs of capture and compression for FOAK plants are expected to be US$110/tCO2 avoided (with a range of US$90-135/tCO2 avoided). For NOAK plants costs are expected to be US$25-50/tCO2. Based on these considerations a likely representative range of costs of abatement from CCS

    We investigated the possibility of AlN synthesis using Li-Al-N solvent. In this work, Li-Al-N solvent was obtained by heating a mixture composed of Al and Li{sub 3}N. First, we studied the relationship between Al/Li{sub 3}N composition of the initial mixture and shape of obtained crystal. The results showed that polyhedral crystals instead of needle-like crystals were obtained under an Al-rich condition, i.e., 4/3<Al/Li{sub 3}N<4/1. Next, we performed AlN synthesis on an AlN/SiC template under an Al-rich condition. The results suggested that a large AlN single-phase region was formed by using the template. The possibility of growth of bulk AlN using Li-Al-N solvent was shown by the present investigations. (Abstract Copyright [2010], Wiley Periodicals, Inc.)

  2. Cost-effectiveness analysis in markets with high fixed costs.

    Science.gov (United States)

    Cutler, David M; Ericson, Keith M Marzilli

    2010-01-01

    We consider how to conduct cost-effectiveness analysis when the social cost of a resource differs from the posted price. From the social perspective, the true cost of a medical intervention is the marginal cost of delivering another unit of a treatment, plus the social cost (deadweight loss) of raising the revenue to fund the treatment. We focus on pharmaceutical prices, which have high markups over marginal cost due to the monopoly power granted to pharmaceutical companies when drugs are under patent. We find that the social cost of a branded drug is approximately one-half the market price when the treatment is paid for by a public insurance plan and one-third the market price for mandated coverage by private insurance. We illustrate the importance of correctly accounting for social costs using two examples: coverage for statin drugs and approval for a drug to treat kidney cancer (sorafenib). In each case, we show that the correct social perspective for cost-effectiveness analysis would be more lenient than researcher recommendations.

    1993-12-01

    Cost-effective nursing practice is essential to succeed today as resources allocated to health care are declining. Realizing that any change poses a threat to our security, it is imperative that stakeholders be permitted to participate in decision-making processes affecting their work. An honest, open exchange of ideas towards cost-effective practices should be encouraged. Cost-effective behaviours are influenced significantly by negative attitudes with regard to loss of human resources, increased workload, and potential pay cuts. This article describes innovative strategies which could promote successful cost-effective nursing practice, including working smarter, not working harder. Topics addressed are attitude, awareness and empowerment.

  4. Costs of Globalization

    Full Text Available Globalization has both costs and benefits. In this paper we would focus upon one of the damages of globalization to China. It is said that inward FDI replaces local domestic capabilities in import-substitution countries. In the case of China the Chinese domesticindustries are lacking technological innovations because of heavy reliance upon FDI. Most of the Chinese exports of electronics are carried under FDI whereas in Korea and Japan they are indigenously-driven. In 1960s, Korea received foreign capital in the formof loans but it denied the entrance to foreign firms. Korea followed the Japanese model by quickly mastering the foreign technology rather than letting foreign firms to establish local subsidiaries and to decide the speed and scope of technology diffusion. Korea andJapan adopted the techno-nationalist policies for attaining autonomous domestic innovated industries. By restricting FDI, Korea and Japan were able to maintain their management independent of Multi-National Companies. In this paper we would try to analyze that whether China’s policy of reliance upon FDI is a success or a debacle by comparing it with Korea and Japan.

    Full Text Available RESUMOEm muitos casos, prevenir a poluição e a destruição do meio ambiente é menos oneroso do que remediar esses danos. Nesse contexto, a alocação de custos ambientais aos produtos permite uma melhor visualização e análise da rentabilidade dos produtos. Entretanto, a alocação dos custos ambientais aos produtos envolve informações estimadas e assume uma linearidade entre o consumo das atividades e os produtos, que muitas vezes não existe. Para contemplar essa não linearidade, esta pesquisa apresenta uma metodologia baseada na utilização da lógica fuzzy para modelar a incerteza e a subjetividade, inerentes ao processo de alocação dos custos ambientais. Para isso, além de um estudo de caso desenvolvido por Hansen e Mowen (2001, p. 584, que foi utilizado como referência, outras variáveis foram incorporadas. Em seguida, uma proposta de solução, que utiliza fundamentos da teoria dos conjuntos fuzzy, ou nebulosos, foi desenvolvida com o objetivo de contemplar a subjetividade e a incerteza na alocação dos custos ambientais. Para simular esse modelo, foram estabelecidas 126 regras de inferência. A etapa final da elaboração do modelo nebuloso consistiu na fuzzificação e defuzzificação dos dados existentes e dos novos direcionadores gerados por intermédio da utilização do software FuzzyTECH®. Os resultados encontrados no modelo proposto - FuzzyABC (Fuzzy Activity Based Costing - evidenciam que a lógica fuzzy pode ser utilizada como uma importante ferramenta para tratar da ambigüidade e da incerteza, inerentes ao processo de alocação dos custos ambientais.ABSTRACTIn many cases, preventing pollution and environmental destruction is cheaper than remedying these damages. In this sense, environmental cost allocation enables a better visualization and analysis of a product’s profitability. However, the environmental allocation process involves estimated information and assumes linearity between activity consumption

    A cluster, randomized, control trial of three dry-season rounds of a mass testing and treatment intervention (MTAT) using rapid diagnostic tests (RDTs) and artemether-lumefantrine (AL) was conducted in four districts in Southern Province, Zambia. Data were collected on the costs and logistics of the intervention and paired with effectiveness estimated from a community randomized control trial for the purpose of conducting a provider perspective cost-effectiveness analysis of MTAT vs no MTAT (Standard of Care). Dry-season MTAT in this setting did not reduce malaria transmission sufficiently to permit transition to a case-investigation strategy to then pursue malaria elimination, however, the intervention did substantially reduce malaria illness and was a highly cost-effective intervention for malaria burden reduction in this moderate transmission area. The cost per RDT administered was estimated to be USD4.39 (range: USD1.62-13.96) while the cost per AL treatment administered was estimated to be USD34.74 (range: USD3.87-3,835). The net cost per disability adjusted life year averted (incremental cost-effectiveness ratio) was estimated to be USD804. The intervention appears to be highly cost-effective relative to World Health Organization thresholds for malaria burden reduction in Zambia as compared to no MTAT. However, it was estimated that population-wide mass drug administration is likely to be more cost-effective for burden reduction and for transmission reduction compared to MTAT.

    In a way to reduce the external energy dependence, increasing also the investments in renewable energy sources and aiming for the concretization of the European renewable objectives, the Portuguese government defined a goal of 5100 MW of installed wind power, up to 2012. If the drawn objectives are accomplished, by 2010 the wind power share may reach values comparable to leading countries like Denmark, Germany or Spain. The Portuguese forecasts also indicate a reinforcement of the natural gas fired generation in particular through the use of the combined cycle technology, following the European tendency. This analysis sets out to evaluate the total generating cost of wind power and CCGT in Portugal. A life cycle cost analysis was conducted, including investment costs, O and M costs, fuel costs and external costs of emissions, for each type of technology. For the evaluation of the externalities ExternE values were used. The results show that presently the wind power production cost is higher than the CCGT one, at least from the strictly financial point of view. CCGT costs increase significantly when charges for externalities are included. However, they only reach levels higher than the equivalents for wind power for high externality costs estimations. This partially results from the low load factor of the wind farms in Portugal and also from the low emission levels of the gas fired technology used in the comparison. A sensitive analysis of the technical and economical parameters was also conducted. Particular attention was given to the natural gas prices due to the possible increase over time. The fuel escalation rate is the parameter that has larger effects on the final costs. It was verified that the total cost of wind plant is more influenced by the load factor than the total cost of CCGT. (au)

    Examining a state-dependent pricing model in the presence of menu costs and dynamic duopolistic interactions, this paper claims that the assumption regarding market structure is crucial for iden- tifying the menu costs for price changes. Prices in a dynamic duopolistic market can be more rigid than those in more competitive markets, such as a monopolistic-competition market. Therefore, the estimates of menu costs under monopolistic competition are potentially biased upward due to the price ri...

    An unusual growth mechanism of metastable zincblende AlN thin film by diffusion of nitrogen atoms into Al lattice is established. Using first-principles density functional theory, we studied the possibility of thermodynamic stability of AlN as a zincblende phase due to epitaxial strains and interface effect, which fails to explain the formation of zincblende AlN. We then compared the formation energetics of rocksalt and zincblende AlN in fcc Al through direct diffusion of nitrogen atoms to Al octahedral and tetrahedral interstitials. The formation of a zincblende AlN thin film is determined to be a kinetically driven process, not a thermodynamically driven process.

    Full Text Available This paper deals with the impact of the most important factors of the total production costs in bioethanol production. The most influential factors are: total investment costs, price of raw materials (price of biomass, enzymes, yeast, and energy costs. Taking into account these factors, a procedure for estimation total production costs was establish. In order to gain insight into the relationship of production and selling price of bioethanol, price of bioethanol for some countries of the European Union and the United States are given.

  1. A Resource Cost Aware Cumulative

    Science.gov (United States)

    Simonis, Helmut; Hadzic, Tarik

    We motivate and introduce an extension of the well-known cumulative constraint which deals with time and volume dependent cost of resources. Our research is primarily interested in scheduling problems under time and volume variable electricity costs, but the constraint equally applies to manpower scheduling when hourly rates differ over time and/or extra personnel incur higher hourly rates. We present a number of possible lower bounds on the cost, including a min-cost flow, different LP and MIP models, as well as greedy algorithms, and provide a theoretical and experimental comparison of the different methods.

  7. Cost-shifting under cost reimbursement and prospective payment.

    Foster, R W

    1985-09-01

    Cost-shifting is seen as a three-way phenomenon involving hospital interests as well as those of government and private patients. Without economies of scale, private patients are indifferent to government policies unless underpayment leads to hospital bankruptcy. In the presence of economies of scale, private patients benefit from reductions in government payment under either cost reimbursement or prospective payment. Their interest in a shift to prospective payment depends upon the hospital's location on its cost curve. Hospitals benefit from increases in payment rates in all cases, but benefit from a shift to prospective payment only if operating in a region of declining average costs. The conventional view of cost-shifting is inconsistent with profit maximization and may be inappropriate for many voluntary hospitals as well.

Thus, developing Islamic education usually begins with a study of a figure and his educational thought. And one of the most influential figures whose thought which has Sufi religious pattern has dominated educational thinking atmosphere over the centuries since his death. The purpose of education according to al-Ghazali was to get closer to Allah. He came with a view that the most noble job is to educate: to become a teacher. Al-Ghazali advised that his students, in the learning process, aim to become scientists who could disseminate their knowledge for the sake of humanity values.

    Full Text Available The evolusionist and functionalist approaches to religion are generally considered less sympathetic if not antipathy to religious phenomena. This is why, some western scholars propose another approach to study religion called ‘phenomenological’ approach. There have been a number of phenomenological studies of religion, but mostly not of  Islam. This article tries to fill in the gap by describing and analyzing the Islamic conception of intention (niyyah developed by al-Sayuthi and al-Ghazali. As a jurist, al-Sayuthi explores different formal rules on niyyah in Islamic jurisprudence, while al-Ghazali as a Sufi, tries to deepen the meaning of niyyah in relation to one’s sincerity to God. Apart from this difference, both conceptions of niyya indicate that as believers, Muslims always attempt to live in the sacred space and time, and make their speech and deed sacred based on the niyyah. Thus, niyya is the very basis of Muslim religious life.

    Previous studies to determine the cost of haemodialysis (HD) in Spain have significant limitations: they are outdated or used indirect methods. There is also a lack of analysis performed simultaneously on Public centres (PC), with direct HD services, and partially state-subsidised centres (SC). This is an important issue since the two systems coexist in Spain. To estimate the cost of HD replacement therapy for chronic renal failure in several centres. This is a prospective and publicly-funded study, which estimates the costs for 2008 using a cost accounting system with specific allocation criteria. We collected demographic and comorbidity data for each centre. Six centres participated, two PC and four SC. There were no significant differences between centres in terms of patient demographics, time on haemodialysis and the Charlson comorbidity index. The total cost per patient per year ranged between € 46, 254 and € 33,130. The cost per patient per year (excluding vascular access and hospital admission) for PC was € 42, 547 and € 39, 289 and for SC € 32 872, € 29, 786, € 35, 461 and € 35, 294 (23% more in PC than SC). Costs related to staff/patient/year and consumables/patient/year were 67% and 83% respectively, higher for PC than SC. The highest percentage cost was for staff (average 30.9%), which showed significant variability between centres, both in absolute numbers (staff cost per patient per year between € 18,151 and € 8504) and as a percentage (between 42.6 % and 25.4%). Cost variability exists among different HD centres, and this can be attributed primarily to staff and consumables costs, which is higher for PC than SC.

    Despite its prevalence and deleterious impact on patients and families, fecal incontinence remains an understudied condition. Few data are available on its economic burden in the United States. The aim of this study was to quantify per patient annual economic costs associated with fecal incontinence. A mail survey of patients with fecal incontinence was conducted in 2010 to collect information on their sociodemographic characteristics, fecal incontinence symptoms, and utilization of medical and nonmedical resources for fecal incontinence. The analysis was conducted from a societal perspective and included both direct and indirect (ie, productivity loss) costs. Unit costs were determined based on standard Medicare reimbursement rates, national average wholesale prices of medications, and estimates from other relevant sources. All cost estimates were reported in 2010 US dollars. This study was conducted at a single tertiary care institution. The analysis included 332 adult patients who had fecal incontinence for more than a year with at least monthly leakage of solid, liquid, or mucous stool. The primary outcome measured was the per patient annual economic costs associated with fecal incontinence. The average annual total cost for fecal incontinence was $4110 per person (median = $1594; interquartile range, $517-$5164). Of these costs, direct medical and nonmedical costs averaged $2353 (median, $1176; interquartile range, $294-$2438) and $209 (median, $75; interquartile range, $17-$262), whereas the indirect cost associated with productivity loss averaged $1549 per patient annually (median, $0; interquartile range, $0-$813). Multivariate regression analyses suggested that greater fecal incontinence symptom severity was significantly associated with higher annual direct costs. This study was based on patient self-reported data, and the sample was derived from a single institution. Fecal incontinence is associated with substantial economic cost, calling for more

Este artículo tiene por objetivo presentar una primera aproximación al cálculo de los costes de la no seguridad referidos al año 2011. Métodos: Para efectuar los cálculos se partió de una estimación de los costes de los pacientes hospitalizados para el año 2005 referentes a los errores de medicación, infecciones nosocomiales y complicaciones quirúrgicas, que se actualizaron al año de referencia. Para los costes de los pacientes no hospitalizados se tuvo en cuenta la Encuesta Nacional de Salud y las estimaciones de la tasa de errores de medicación y de los costes de los tratamientos procedentes de otros autores. Resultados: El coste de la no seguridad en los pacientes hospitalizados fue de 2.474 millones de euros y de 960 millones de euros para los pacientes no hospitalizados Conclusiones: Esta estimación indica que los costes de la no seguridad.

    Full Text Available The developed design methodologies both the material and technological ones will make it possible to improve shortly the quality of materials from the light alloys in the technological process, and the automatic process flow correction will make the production cost reduction possible, and - first of all - to reduce the amount of the waste products. Method was developed for analysis of the casting defects images obtained with the X-ray detector analysis of the elements made from the Al-Si-Cu alloys of the AC-AlSi7Cu3Mg type as well as the method for classification of casting defects using the artificial intelligence tools, including the neural networks; the developed method was implemented as software programs for quality control. Castings were analysed in the paper of car engine blocks and heads from the Al-Si-Cu alloys of the AC-AlSi7Cu3Mg type fabricated with the “Cosworth” technological process. The computer system, in which the artificial neural networks as well as the automatic image analysis methods were used makes automatic classification possible of defects occurring in castings from the Al-Si-Cu alloys, assisting and automating in this way the decisions about rejection of castings which do not meet the defined quality requirements, and therefore ensuring simultaneously the repeatability and objectivity of assessment of the metallurgical quality of these alloys.

    Full Text Available The opportunity cost of the capital invested in pharmaceutical research and development (R&D to bring a new drug to market makes up as much as half the total cost. However, the literature on the cost of pharmaceutical R&D is mixed on how, exactly, one should calculate this “hidden” cost. Some authors attempt to adopt models from the field of finance, whereas other prominent authors dismiss this practice as biased, arguing that it artificially inflates the R&D cost to justify higher prices for pharmaceuticals. In this article, we examine the arguments made by both sides of the debate and then explain the cost of capital concept and describe in detail how this value is calculated. Given the significant contribution of the cost of capital to the overall cost of new drug R&D, a clear understanding of the concept is critical for policy makers, investors, and those involved directly in the R&D.

    Viable processes were developed for secondary working of oxide dispersion strengthened (ODS) alloys to near-net shapes (NNS) for aircraft turbine vanes. These processes were shown capable of producing required microstructure and properties for vane applications. Material cost savings of 40 to 50% are projected for the NNS process over the current procedures which involve machining from rectangular bar. Additional machining cost savings are projected. Of three secondary working processes evaluated, directional forging and plate bending were determined to be viable NNS processes for ODS vanes. Directional forging was deemed most applicable to high pressure turbine (HPT) vanes with their large thickness variations while plate bending was determined to be most cost effective for low pressure turbine (LPT) vanes because of their limited thickness variations. Since the F101 LPT vane was selected for study in this program, development of plate bending was carried through to establishment of a preliminary process. Preparation of ODS alloy plate for bending was found to be a straight forward process using currently available bar stock, providing that the capability for reheating between roll passes is available. Advanced ODS-NiCrAl and ODS-FeCrAl alloys were utilized on this program. Workability of all alloys was adequate for directional forging and plate bending, but only the ODS-FeCrAl had adequate workability for shaped preform extrustion.

    - Two recent societal cost-benefit analyses have documented the costs of smoking and the cost-effectiveness of preventing smoking.- Smoking costs the Netherlands society EUR 33 billion per year.- The majority of this is the monetary value of health loss; these are "soft" euros that cannot be re-spent.- There is not a great deal of difference between costs and benefits when expressed in "hard" euros, which means that there is no clear business case for anti-smoking policy.- The greatest benefit of discouraging smoking is improved health for the individual and increased productivity for the business sector; however, the benefits cannot be easily realised, because even in the most favourable scenario the number of smokers will decrease slowly.- Excise duties seem to offer the most promising avenue for combating smoking. The benefits of anti-smoking policy, therefore, consist mainly of tax revenues for the government.- Stringent policy is required to transform tax revenues into health gains.

    The capacity per unit cost, or equivalently minimum cost to transmit one bit, is a well-studied quantity. It has been studied under the assumption of full synchrony between the transmitter and the receiver. In many applications, such as sensor networks, transmissions are very bursty, with small amounts of bits arriving infrequently at random times. In such scenarios, the cost of acquiring synchronization is significant and one is interested in the fundamental limits on communication without assuming a priori synchronization. In this paper, we show that the minimum cost to transmit B bits of information asynchronously is (B + \\bar{H})k_sync, where k_sync is the synchronous minimum cost per bit and \\bar{H} is a measure of timing uncertainty equal to the entropy for most reasonable arrival time distributions.

    Natural disasters or attacks often disrupt infrastructure networks requiring a costly recovery. This motivates an optimization problem where the objecitve is to construct the nodes of a graph G(V;E), and the cost of each node is dependent on the number of its neighbors previously constructed, or more generally, any properties of the previously-completed subgraph. In this optimization problem the objective is to find a permutation of the nodes which results in the least construction cost. We prove that in the case where the cost of nodes is a convex function in the number of neighbors, the optimal construction sequence is to start at a single node and move outwards. We also introduce algorithms and heuristics for solving various instances of the problem. Those methods can be applied to help reduce the cost of recovering from disasters as well as to plan the deployment of new network infrastructure.

    We have overestimated the ability of electronic health records (EHR) systems to enhance efficiency by eliminating transcription and the need to physically pull charts. Hospital managers typically underestimate the costs of upgrade fees and support. To avoid this problem, hospitals must develop a full total cost of ownership (TCO) analysis to independently forecast total lifecycle costs for EHR information technology. Vendor information must be checked for validity and a milestone payment schedule must be devised to pay for results (outcomes) not promises. Vendors vary widely in their capacity to set up a fully functional inpatient-outpatient EHR system. Documentation programming will help to control hospital costs while enhancing service quality and staff morale. This study presents cost analysis from 62 hospitals in 16 cities during the period 2012-2013.

    Several groups are implementing low‐cost host‐operated systems of strong‐motion accelerographs to support the somewhat divergent needs of seismologists and earthquake engineers. The Advanced National Seismic System Technical Implementation Committee (ANSS TIC, 2002), managed by the U.S. Geological Survey (USGS) in cooperation with other network operators, is exploring the efficacy of such systems if used in ANSS networks. To this end, ANSS convened a working group to explore available Class C strong‐motion accelerometers (defined later), and to consider operational and quality control issues, and the means of annotating, storing, and using such data in ANSS networks. The working group members are largely coincident with our author list, and this report informs instrument‐performance matters in the working group’s report to ANSS. Present examples of operational networks of such devices are the Community Seismic Network (CSN; csn.caltech.edu), operated by the California Institute of Technology, and Quake‐Catcher Network (QCN; Cochran et al., 2009; qcn.stanford.edu; November 2013), jointly operated by Stanford University and the USGS. Several similar efforts are in development at other institutions. The overarching goals of such efforts are to add spatial density to existing Class‐A and Class‐B (see next paragraph) networks at low cost, and to include many additional people so they become invested in the issues of earthquakes, their measurement, and the damage they cause.

  9. The Psychology of Cost Estimating

    Cost estimation for large (and even not so large) government programs is a challenge. The number and magnitude of cost overruns associated with large Department of Defense (DoD) and National Aeronautics and Space Administration (NASA) programs highlight the difficulties in developing and promulgating accurate cost estimates. These overruns can be the result of inadequate technology readiness or requirements definition, the whims of politicians or government bureaucrats, or even as failures of the cost estimating profession itself. However, there may be another reason for cost overruns that is right in front of us, but only recently have we begun to grasp it: the fact that cost estimators and their customers are human. The last 70+ years of research into human psychology and behavioral economics have yielded amazing findings into how we humans process and use information to make judgments and decisions. What these scientists have uncovered is surprising: humans are often irrational and illogical beings, making decisions based on factors such as emotion and perception, rather than facts and data. These built-in biases to our thinking directly affect how we develop our cost estimates and how those cost estimates are used. We cost estimators can use this knowledge of biases to improve our cost estimates and also to improve how we communicate and work with our customers. By understanding how our customers think, and more importantly, why they think the way they do, we can have more productive relationships and greater influence. By using psychology to our advantage, we can more effectively help the decision maker and our organizations make fact-based decisions.

    This work demonstrates a novel transparent electrode using embedded Al grids fabricated by a simple and cost-effective approach using photolithography and wet etching. The optical and electrical properties of Al grids versus grid geometry have been systematically investigated, it was found that Al grids exhibited a low sheet resistance of 70 Ω □-1 and a light transmission of 69% at 550 nm with advantages in terms of processing conditions and material cost as well as potential to large scale fabrication. Indium Tin Oxide-free green organic light-emitting diodes (OLED) based on Al grids transparent electrodes was demonstrated, yielding a power efficiency >15 lm W-1 and current efficiency >39 cd A-1 at a brightness of 2396 cd m-2. Furthermore, a reduced efficiency roll-off and higher brightness have been achieved compared with ITO-base device.

    2016-04-01

    In Allamano et al. (2015), we propose to retrieve quantitative measures of rainfall intensity by relying on the acquisition and analysis of images captured from professional cameras (SmartRAIN technique in the following). SmartRAIN is based on the fundamentals of camera optics and exploits the intensity changes due to drop passages in a picture. The main steps of the method include: i) drop detection, ii) blur effect removal, iii) estimation of drop velocities, iv) drop positioning in the control volume, and v) rain rate estimation. The method has been applied to real rain events with errors of the order of ±20%. This work aims to bridge the gap between the need of acquiring images via professional cameras and the possibility of exporting the technique to low-cost webcams. We apply the image processing algorithm to frames registered with low-cost cameras both in the lab (i.e., controlled rain intensity) and field conditions. The resulting images are characterized by lower resolutions and significant distortions with respect to professional camera pictures, and are acquired with fixed aperture and a rolling shutter. All these hardware limitations indeed exert relevant effects on the readability of the resulting images, and may affect the quality of the rainfall estimate. We demonstrate that a proper knowledge of the image acquisition hardware allows one to fully explain the artefacts and distortions due to the hardware. We demonstrate that, by correcting these effects before applying the image processing algorithm, quantitative rain intensity measures are obtainable with a good accuracy also with low-cost modules.

    AlGaN solar-blind avalanche photodiodes (APDs) with AlInN/AlGaN distributed Bragg reflectors (DBRs) operated at lower avalanche breakdown voltage are numerically demonstrated. The p-type AlGaN layer and the multiplicative layer with low Al composition are introduced to construct the polarization-induced electric field, which can significantly reduce the avalanche breakdown voltage of the APDs. Calculated results exhibit that the avalanche breakdown voltage of the designed APDs decrease by 13% compared with the conventional device structure. Simultaneously, an improved solar-blind spectral responsivity is achieved due to the inserted AlInN/AlGaN DBRs.

  20. First principles calculation of ac conductance for Al-BDT-Al and Al-Cn-Al systems

    Full Text Available We perform first-principles calculation to investigate the dynamic conductance of atomic wires of the benzenedithiol (BDT as well as carbon chains with different length in contact with two Al(100 electrodes (Al-Cn-Al. Our calculation is based on the combination of the non-equilibrium Green's function and the density functional theory. For ac conductance, there are two theories that ensures the current conservation: (1. the global formula which is a phenomenological theory that partitions the total displacement current into each leads so that the current is conserved.(2. the local formula which is a microscopic theory that includes Coulomb interaction explicitly so that the current is conserved automatically. In this work, we use the local formula to calculate the dynamic conductance, especially the emittance. We give a detailed comparison and analysis for the results obtained from two theories. Our numerical results show that the global formula overestimates the emittance by two orders of magnitude. We also obtain an inequality showing that the emittance from global formula is greater than that from local formula for real atomic structures. For Al-Cn-Al structures, the oscillatory behavior as the number of carbon chain N varies from even to odd remains unchanged when local formula is used. However, the prediction of local formula gives rise to opposite response when N is odd (inductive-like as compared with that of global formula. Therefore, one should use the local formula for an accurate description of ac transport in nanoscale structures. In addition, the ‘size effect’ of the ac emittance is analyzed and can be understood by the kinetic inductance. Since numerical calculation using the global formula can be performed in orbital space while the local formula can only be used in real space, our numerical results indicate that the calculation using the local formula is extremely computational demanding.
