    This paper reports on nuclear export activities in Spain, as elsewhere, which occur in a political, economic, and technological context. The factors operating the process are not always explicitly related in the public and the private sectors, nor between these sectors, by the relevant decision makers. A redefinition of Spain's policies in the nuclear sector has been going on since at least 1984, when a new energy plan was legislated by the newly elected Socialist government. It would be accurate to suggest that this process remains dynamic and not fully completed for policy purposes. This condition has resulted from the fact that Spain underwent a crucial political regime change from dictatorship to parliamentary democracy about a decade ago, with the transition to democracy only recently consolidated. Moreover, no policy in regard to nuclear nonproliferation existed during the Franco regime. Instead, Spain's official position was to maintain the right to preserve a nuclear option for national defense. However, this option was not developed into a concerted program to develop a nuclear military capability

    Spain is a constitutional monarchy with a population of 38.3 million growing at .5%/year. The most striking topographical features are the high plateaus and internal compartmentalization by mountain and river barriers. Nearly 3/4 of the country is arid. The Iberian peninsula was the scene of successive invasions and warfare for centuries. Phoenicians, Greeks, Carthaginians, Moors, Celts, Romans, and Visigoths all invaded at some time. The present language, religion, and laws stem from the Roman Period. The Reconquest from the North African Moors lasted over 700 years until they were driven out in 1492. The unification of present day Spain was complete by 1512. A period of dictatorial rule from 1923-31 ended with establishment of the Second Republic which saw increasing political polarization culminating in the Spanish Civil War. Franco's victory in 1939 was followed by official neutrality but pro-Axis policies during World War II. Spain's economy began to recover during the 1950s, but large scale modernization and development did not occur until the 1960s. Prince Juan Carlos de Borbon y Borbon, Franco's personally designated heir, assumed the title of king and chief of state with Franco's death in 1975. Franco's last prime minister was replaced in July 1976 in order to speed the pace of post-Franco liberalization. Spain's 1st parliamentary elections since 1936 were held in 1977, and a new constitution protecting human and civil rights and granting due process was overwhelmingly approved in 1978. The constitution also authorized creation of regional autonomous governments. By the mid-1970s, Spain had developed a strong and diversified industrial sector and a thriving tourist industry. From 1975-83, there were 8 years of double-digit inflation, an average growth rate of 1.5% in real terms, and an increase in unemployment from about 4.7% to 18.4%. By 1984 there was substantial improvement in inflation and the balance of payments. Goals of current government economic

    Spanish low and intermediate level radioactive wastes are disposed of at the El Cabril Disposal Facility, in the province of Cordoba (SPAIN). The fundamental safety objective of the facility consists of the immediate and longer term protection of people and the environment. This objective leads to the need to isolate the wastes from the human surroundings, such that any release of the radionuclides contained in them does not pose any radiological risk for either people or the environment over the necessary time period. Consequently, it is necessary to fully protect the wastes against external aggression, from both the climatic and biological point of view (infiltration of water, temperature variations, chemical action of water, attacks by living macro and microorganisms, plants, etc.). This waste isolation is achieved by means of a multi-barrier system separating the activity stored from the aforementioned actions

    Full Text Available La neuromielitis óptica es una enfermedad desmielinizante idiopática, severa, del sistema nervioso central que afecta principalmente el nervio óptico y la médula espinal. Los hallazgos clínicos, imagenológicos e inmunológicos permiten diferenciar la neuromielitis óptica de los casos severos de esclerosis múltiple. Los anticuerpos de inmunoglobulina G (IgG-NMO en el suero sirven como marcador específico de la neuromielitis óptica. La IgG de la NMO es el primer marcador específico de una enfermedad desmielinizante del sistema nervioso central. El blanco molecular de la IgG-NMO identificado es el canal de acuaporina 4, abundante a nivel cerebral y se encuentra en la membrana plasmática de los astrocitos. La seropositividad de IgG-NMO ha sido incorporada en los nuevos criterios de diagnóstico de neuromielitis óptica. La presentación clínica y el curso de la enfermedad puede ser con recaídas en 80-90% y en un 10-20% curso monofásico. La terapia con corticosteroides intravenosos normalmente es el tratamiento inicial para los ataques agudos de neuritis óptica o mielitis. La plasmaféresis es la terapia de rescate cuando no hay respuesta a los esteroides durante los ataques de neuromielitis óptica. Los agentes inmunosupresores se usan para la prevención de las recaídas. El tratamiento con inmunosupresores está indicado en los pacientes con diagnóstico de neuromielitis óptica y recaídas.

    With a variety of high-quality live interactive educational programs originating at the Johnson Space Center in Houston, Texas and other space and research centers, the US space agency NASA (National Aeronautics and Space Administration) has a proud track record of connecting with students throughout the world and stimulating their creativity and collaborative skills by teaching them underlying scientific and technological underpinnings of space exploration. However, NASA desires to expand its outreach capability for this type of interactive instruction. In early 2002, NASA and the National Guard Bureau -- using the Guard's nationwide system of state-ofthe-art classrooms and high bandwidth network -- began a collaboration to extend the reach of NASA content and educational programs to more of America's young people. Already, hundreds of elementary, middle, and high school students have visited Guard e-Learning facilities and participated in interactive NASA learning events. Topics have included experimental flight, satellite imagery-interpretation, and Mars exploration. Through this partnership, NASA and the National Guard are enabling local school systems throughout the United States (and, increasingly, the world) to use the excitement of space flight to encourage their students to become passionate about the possibility of one day serving as scientists, mathematicians, technologists, and engineers. At the 54th International Astronautical Conference MAJ Stephan Picard, the guiding visionary behind the Guard's partnership with NASA, and Chris Chilelli, an educator and senior instructional designer at NASA, will share with attendees background on NASA's educational products and the National Guard's distributed learning network; will discuss the unique opportunity this partnership already has provided students and teachers throughout the United States; will offer insights into the formation by government entities of e-Learning partnerships with one another; and will

    Historically, Spain's nuclear program has had its share of successes and challenges. The country currently operates nine nuclear reactors totalling over 7,100 MWe of capacity and accounting for more than a third of Spain's electricity generation. Yet four reactors at advanced stages of construction remain mothballed due to a government-imposed moratorium, and a fire at one reactor in 1989 led to its premature closure and to a revival of anti-nuclear sentiment in the country. In the new national energy plan, Spain opted to continue the moratorium and rely upon conservation measures, additional natural gas imports, and electricity imports to meet expected demand. The current nuclear facilities will continue to operate, and the government will continue to pursue advanced reactor research, and expansion of the country's domestic uranium industry. Spain's integration into the European Community also is affecting the country's energy plans, prompting consolidation within the Spanish electricity sector in order to be more competitive in Europe

    He leído de manera detallada el reporte de caso titulado “Neuromielitis óptica (Enfermedad de Devic” (1. En él se presenta la evolución común así como las dificultades del manejo de esta patología, en particular en su proceso diagnóstico. Como se pudo observar en esta paciente, es común la confusión entre neuromielitis óptica y esclerosis múltiple, y este error puede deteriora la calidad de vida y empeorar el cuadro del paciente, dado que tanto su etiologías como su manejo son bastantes diferentes (2–5. Por esta razón, es necesario contar con exámenes paraclínicos que permitan diferenciarlas; las pruebas inmunológicas para la detección de anticuerpos contra acuaporina 4 (AQP4, disponibles desde hace más de diez años, permiten clasificar estas enfermedades de manera adecuada (6.

    Debido a la capacidad de las pruebas de laboratorio para distinguir entre estas dos enfermedades, y a la inexistencia de laboratorios para su detección en el país, en 2014, con financiación del Ministerio de Salud y Protección Social, y bajo supervisión del Instituto de Evaluación de Tecnologías en Salud (IETS, la Universidad Javeriana realizó un estudio para evaluar las características operativas de los anticuerpos contra AQP4 (7.

Se tienen en cuenta varios aspectos como: la posibilidad de los fármacos antiulcerosos de interaccionar con otros principios activos y alimentos, además de los efectos no deseados que se presentan; los tratamientos de triples y cuádruples terapias que constituyen una limitante para el paciente por el gran número de medicamentos a administrar; y por último, el actual incremento de la resistencia antibiótica, se hace necesario la búsqueda de otras alternativas para el control de esta enfermedad. Un nuevo camino que brinda grandes posibilidades es la medicina alternativa, es decir, los fitofármacos.

    Full Text Available The clinical triad of septo-optic dysplasia (SOD comprises the absence of the septum pellucidum, congenital optic nerve dysplasia, and multiple endocrine disorders. When any two of these factors are present, the condition is defined as an incomplete form of SOD. The authors report the case of an incomplete form of SOD in a 9-year-old boy with low vision and nystagmus present from birth. The bilateral ophthalmoscopic examination revealed small papillae with double contour images. Magnetic resonance imaging showed hypoplasia of the optic nerve bilaterally, chiasm and absence of the septum pellucidum.A tríade clínica da displasia septo-óptica (DSO compreende a ausência de septo pelúcido, displasia congênita do nervo óptico e múltiplos defeitos endócrinos. Uma forma incompleta de DSO tem sido reconhecida com dois dos três elementos. Os autores relatam um caso de displasia septo-óptica na forma incompleta em um garoto de 9 anos com baixa visão e nistagmo presentes desde o nascimento. O exame oftalmoscópico revelou papila pequena com imagem em duplo contorno bilateralmente. Ressonância magnética mostrou hipoplasia dos nervos ópticos, quiasma e ausência do septo pelúcido.

    Full Text Available Descrevemos uma paciente de 9 anos, sexo feminino, com perda visual bilateral grave tratada com corticóide por via oral apresentando melhora em apenas um olho. Nove anos depois apresentou recidiva que inicialmente respondeu à pulsoterapia corticóide mas foi seguida de perda progressiva e completa da visão após a redução do tratamento. Novas tentativas terapêuticas não melhoraram a visão. Avaliação clínico-laboratorial não revelou doença sistêmica, mas apresentava anticorpos antinucleares (1/640, anti-Ro e anti-La positivos. Neuropatia óptica auto-imune é uma afecção rara, que simula neurite óptica idiopática e se caracteriza por perda visual aguda, sem doença sistêmica, mas com evidências laboratoriais de doença auto-imune, em especial o FAN positivo. Biópsia de pele freqüentemente mostra evidências de vasculite. Esta condição deve ser tratada agressivamente, com corticóide e imunossupressores, uma vez que o acometimento visual geralmente é mais grave do que o da neurite óptica idiopática/desmielinizante e pode ser irreversível.We report on a 9-year-old female patient who had bilateral severe visual loss and was treated with oral corticosteroids. Visual improvement occurred in one eye. Nine years later she presented relapse of visual loss in her only seeing eye. Pulse corticosteroid therapy resulted in dramatic visual improvement followed, however, by progressive and complete visual loss as soon as the corticosteroid was tapered. Repeat treatment did not result in visual improvement. Clinical and laboratory investigation failed to find a systemic disease but the patient had positive antinuclear (1/640, anti-Ro and anti-La antibodies. Autoimmune optic neuropathy is a rare condition that may mimic an idiopathic optic neuritis and is characterized by acute visual loss, without systemic disease but with laboratory evidence of an autoimmune disorder, usually a positive ANA.

    Basicamente, são propostos dois cenários de evolução quí mio-dinâmico para os sistemas esferoidais: (i) o hierárquico através da fusão e/ou acresção de sub-sistemas com ou sem surtos de formação estelar, e (ii) o colapso monolí tico dissipativo com formação estelar interrompida por um vento galáctico. Ambos, dentro de certos limites, conseguem explicar os gradientes internos de metalicidade estelar presentes nas galáxias elí pticas bem como a relação observada entre a metalicidade central e a massa (Mg20 vs. log sv0). No entanto, nenhum prevê uma variação interna para a razão de abundâncias Mg/Fe que indiretamente define a escala temporal da formação estelar. Empregamos a espectroscopia óptica de fenda longa com a finalidade de recuperar as histórias de formação estelar, de enriquecimento quí mico e da dinâmica dentro de determinadas regiões das galáxias. Os espectros de média resolução (FWHM = 7,1 Å) e escala angular de 1,092 arcsec/pixel foram coletados com o telescópio 1,60m do OPD/LNA. Comparamos nossas medidas de linhas de absorção com resultados espectrofotométricos de modelos de populações estelares simples - mais especificamente os í ndices do Sistema Lick como Mg2, Mg b, e Hb - a fim de se investigar as variações internas de [Fe/H], [Mg/Fe] e idade. Para duas galáxias elí pticas, NGC 1052 e NGC 7796, pertencentes a ambientes de baixa densidade, encontramos uma variação radial da razão Mg/Fe decrescente do centro para fora em regiões de 0,6 e 1 raio efetivo respectivamente. Discutimos alguns cenários de enriquecimento quí mico para estas duas galáxias.

Debido a lo anterior, comienzan a producirse ciertos fenómenos ópticos no lineales como la mezcla de cuarta onda (Four Wave Mixing, FWM, que degradan la señal de información. En este documento se realiza un estado del arte de la fibra óptica y un estudio del fenómeno no lineal FWM, que se genera cuando dos o más señales ópticas se propagan en la fibra, lo cual conlleva a una mezcla de señales que puede generar nuevos componentes de interferencia de la señal óptica transmitida. ABSTRACT To make better use of the bandwidth that has the optical fiber, optical communications systems have had to increase the transmission power of signals to transport information over long distances.

  10. Spain's uranium industry

    International Nuclear Information System (INIS)

    Ferguson, M.P.

    1992-01-01

    Spain currently operates nine nuclear reactors totalling over 7,100 MWe of capacity, contributing about one-third of all electricity generated in Spain. Four reactors at advanced stages of construction remain mothballed as the result of a government-imposed moratorium, and a fire at Vandellos 1 in 1989 led to its premature closure and to a revival of anti-nuclear sentiment in the country. In the new national energy plan, which was sent to the Spanish Parliament on July 25, 1991, Spain opted to continue the nuclear moratorium that began in 1984 and rely upon conservation measures, additional natural gas imports, and electricity imports to meet expected demand. Under the new plan, nuclear power's share of Spain's total installed electrical generating capacity will fall from about 17 percent in 1990, to approximately 14 percent by the end of the century, as only the current nuclear facilities will continue to operate and no new nuclear plants will be built. Spain's integration into the European Community also is affecting the country's energy plans, prompting consolidation within the Spanish electricity sector in order to be more competitive in Europe. To supply the existing reactors, the government is supporting a major expansion of the country's domestic uranium industry

En la actualidad no existe un tratamiento eficaz para la neuropatía óptica hereditaria de Leber, pero el consejo genético en portadores asintomáticos es importante. Presentamos el caso clínico de un paciente de ...

  6. Nuclear energy in Spain

    Isla, M.

    1984-01-01

    The 'Plan Energetico Nacional de 1983' (1983 National Energy Program)(PEN-83) was approved recently by the Spanish Government and presented to the 'Cortes Espanolas' (Spanish Parliament) in May 1984. The PEN-83 is being discussed at present in the Parliament and it is possible that some modifications be introduced, but expectedly will be rather limited and minor. PEN-83 covers the period 1983-1992. It includes a comparative analysis of the evolution and situation in OECD countries and in Spain. In Spain the offer, supply and consumption of primary energy and of the interrelation with other economic indicators, such as the gross domestic product, inflation rate and unemployment compared with that of the industrialized OECD countries, has shown a much lower capability to adapt its structure to the energy price increases

    Emergencies due to snakebites, although unusual in Spain, are potentially serious. Of the 13 species native to the Iberian peninsula, only 5 are poisonous: 2 belong to the Colubridae family and 3 to the Viperidae family. Bites from these venemous snakes can be life-threatening, but the venomous species can be easily identified by attending to certain physical traits. Signs denoting poisoning from vipers, and the appropriate treatment to follow, have changed in recent years.

The A.A. isolated Pneumococcus from 10 out the 20 cases, Gonococcus from 2, Staphylococcus from 2, Streptococcus from 5 and Friedlaender bacil¬lus from 1 . The A.A. mainly lay stress on the necessity of the bacteriological exa¬minations being made by a specialist, owing to the difficulties sometimes met with and to the consequences of a detailed examination of the isolated germ.Expomos e analisamos, no presente trabalho, as principais idéias emitidas acerca das endocardites sépticas. De grande importância foram as de Schottmueller sôbre o caráter autônomo da endocardite lenta, assim a especificidade do seu agente etiológico. Observações posteriores trouxeram restrições à teoria desse autor e as nossas se encontram nesse número, conforme se poderá ver no capitulo anterior. Além do Streptococcus viridans muitas outras bactérias têm ocasionado casos clínicos típicos de endocardite lenta ou sub-aguda. Outro ponto para o qual se têm dirigido os pesquisadores é o que trata da mutação do Streptococcus haemohjticus em Streptococcus viridans, o pri¬meiro dado como mais freqüente nas endocardites agudas. A tendência dos modernos autores é nesse sentido e nós temos observado, não raro, mutações dessa natureza. Há mesmo autores que admitem uma só espécie de estrepto-coco não passando de acidentes ocasionados por diferentes fatores físicos, químicos e biológicos as características descritas pelos que admitem várias espécies. As hemoculturas nem sempre foram positivas nos nossos casos, o que têm acontecido a todos os autores que estudaram o assunto. Em primeiro

    Full Text Available Antiepileptic drugs may cause worsening of epilepsy by aggravating pre-existing seizures or by triggering new seizure types. There are several reports of adverse effects related to midazolam, but only a few authors reported epileptic manifestations. We report four newborns seen at the Neonatal Intensive Care Unit of our University Hospital, who developed seizures a few seconds after the administration of midazolam. It is difficult to identify the patients at risk, but it is important to be aware and recognize this situation.Drogas antiepilépticas podem piorar o controle da epilepsia por agravar crises epilépticas pre-existentes ou por desencadear novos tipos de crises. Existem vários relatos de eventos adversos relacionados ao midazolam; entretanto, poucos autores referem manifestações epilépticas. Neste estudo relatamos a ocorrência de crises epilépticas poucos segundos após a administração de midazolam, em quatro neonatos atendidos na Unidade de Terapia Intensiva do nosso hospital universitário. É difícil determinar quais pacientes estão em risco, mas é importante estar atento e reconhecer esta situação.

    2006-03-01

    Spain presents one of the lowest suicide rates (8.7 per 100,000) but, as well as Ireland, it has also experienced one of the highest rate increases both within Europe and within the world. In our country, it can be observed an increase in the suicide rates from 1975 to 1994, being this increase greater in men than in women. It can also be noted that there was a stabilisation in the following years. Social factors, specially those which have to deal with gender roles and changes in these roles, are the most common explanations. Another possible explanation for the observed increase in mortality due to suicide among young men could be the AIDS epidemic and intravenous drug addiction, that was observed in Spain during the eighties and nineties. Furthermore, we are witnessing an epidemic related to violence against children and women. Literature strongly suggests that child abuse (psychological and sexual) is associated with increased suicide risk in adolescent or adult life. Women experience violence from their intimate partners and have a greater risk of suffering from chronic pain, diverse somatisations, greater substance use like drugs and alcohol, depression and suicide attempt. The association between work precariousness and suicide seems to be due to economic and social and family support factors, which can lead to greater vulnerability to mental health problems. These factors are of great relevance, since Spain presents one of the highest unemployment and temporary employment rates in the European Union. It seems reasonable that, due to the individualism that characterises the contemporary society, its demands and the new role of women in the work market that cause, among others, a greater difficulty in combining work and family life, are factors that could explain the lack of decrease in suicide rates.

En nuestro hospital la úlcera péptica perforada tiene una elevada morbilidad y mortalidad, mayor del 20 % en los últimos 5 años, lo que nos motivó a realizar este trabajo. MÉTODOS. Se realizó un estudio descriptivo y prospectivo de los pacientes tratados por úlcera péptica perforada en el Servicio de Cirugía General del Hospital Universitario «Manuel Ascunce Domenech» de Camagüey, durante los años 2006 y 2007. RESULTADOS. La úlcera péptica perforada predominó en los hombres entre 40 y 59 años de edad. El 41,2 % tenían antecedentes de úlcera péptica, aunque solo la mitad recibía tratamiento médico. La mayoría de los pacientes fueron atendidos entre 13 y 24 h del inicio de su cuadro clínico, y hubo pocos casos de shock, deshidratación u otra enfermedad grave asociada. La úlcera duodenal perforada fue la más frecuente (67,6 % y la sutura y la epiploplastia fueron las técnicas quirúrgicas más usadas. La mortalidad fue del 5,9 %, debida a falla múltiple de órganos y sepsis respiratoria grave. CONCLUSIONES.

    Full Text Available La neuropatía óptica hereditaria de Leber es una enfermedad de herencia materna que se caracteriza por la pérdida subaguda, indolora y bilateral, aunque por lo general no siempre al unísono de la visión central. Predomina en hombres jóvenes y es causada por mutaciones puntuales del ADN mitocondrial. Esta es una de las neuropatías ópticas hereditarias más frecuentes y altamente invalidante, cuyo diagnóstico de certeza lo constituyen los estudios moleculares. El propósito de esta revisión es alertar en cuanto a su diagnóstico y posible incremento en condiciones ambientales favorecedoras. Se realizó una búsqueda automatizada de artículos científicos relacionados con el tema, en PUBMED e Hinari, que resultó en 37 publicaciones realizadas durante los años 1988-2010. Se estudiaron y discutieron aspectos de la enfermedad tales como antecedentes históricos, factores de riesgo, epidemiología, genética, características clínicas, diagnóstico y tratamiento; además de profundizar en su estado actual en nuestro contexto. En Cuba actualmente se conoce de la existencia de varias familias que padecen la neuropatía óptica hereditaria de Leber. El alza de la incidencia probablemente se debió a las condiciones medioambientales que favorecen o son factores de riesgo de esta entidad, como ocurrió durante la pasada epidemia de neuropatía óptica en Cuba. Cada día se producen más avances en el campo de la genética, que permiten identificar un número mayor de mutaciones asociadas a esta entidad. Esto unido al conocimiento de las características clínicas de la enfermedad ha permitido identificar las familias afectadas y actuar sobre los factores de riesgo.Leber´s hereditary optic neuropathy is a maternally inherited disease characterized by subacute, painless and bilateral loss of the central vision, although not always at the same time.

    The second OECD Review of Spain's environmental performance reviews Spain's progress in the context of OECD environmental strategy for the first decade of the 21st century in relation to its own policy objectives. It praises a number of achievements such as in commitments to climate change policies and developments of cogeneration and renewable energy sources. Although emissions of sulphur dioxide from the energy sector have fallen since 1990 they are still high when measured per capita and per unit of GDP. The OECD recommends further control of emissions of SOx, NOx, VOCs and NH{sub 3}. Subsidies such as compulsory purchase of domestic coal by electricity producers are set to increase. The report recommends the phasing out of environmental subsidies (which has begun) and making use of economic instruments to encourage efficient resource management and reduction of pollutants. Greenhouse gas emissions increased by 38% between 1990 and 2002 and the outlook for the next few years is pessimistic. 39 figs., 31 tabs.

    2007-01-01

    Carlos Villota. Director of Nuclear Energy of UNESA gave an overview of the Spanish nuclear industry, the utility companies and the relevant institutions. Companies of the nuclear industry include firms that produce heavy components or equipment (ENSA), manufacturers of nuclear fuel (ENUSA), engineering companies, the National Company for Radioactive Waste Management (ENRESA), and nuclear power plants (nine units at seven sites). Nuclear energy is a significant component of the energy mix in Spain: 11% of all energy produced in Spain is of nuclear origin, whilst the share of nuclear energy in the total electricity generation is approximately 23%. The five main players of the energy sector that provide for the vast majority of electricity production, distribution, and supply have formed the Spanish Electricity Industry Association (UNESA). The latter carries out co-ordination, representation, management and promotion tasks for its members, as well as the protection of their business and professional interests. In the nuclear field, UNESA through its Nuclear Energy Committee co-ordinates aspects related to nuclear safety and radiological protection, regulation, NPP operation and R and D. Regarding the institutional framework of the nuclear industry, ENSA, ENUSA and ENRESA are controlled by the national government through the Ministry of Economy and Finance and the Ministry of Science and Technology. All companies of the nuclear industry are licensed by the Ministry of Industry, Tourism and Trade (MITYC), while the regulatory body is the Nuclear Safety Council (CSN). It is noteworthy that CSN is independent of the government, as it reports directly to Parliament. (author)

    Full Text Available Entre las enfermedades que afectan al hombre y provocan alteraciones en su vida individual y social se encuentra la úlcera péptica, muy frecuente en casi todos los países del mundo. La úlcera péptica viene asociada generalmente al consumo de antiinflamatorios no esteroidales o a la infección por Helicobacter pylori, por lo que el tratamiento farmacológico difiere entre un caso u otro. Se tienen en cuenta varios aspectos como: la posibilidad de los fármacos antiulcerosos de interaccionar con otros principios activos y alimentos, además de los efectos no deseados que se presentan; los tratamientos de triples y cuádruples terapias que constituyen una limitante para el paciente por el gran número de medicamentos a administrar; y por último, el actual incremento de la resistencia antibiótica, se hace necesario la búsqueda de otras alternativas para el control de esta enfermedad. Un nuevo camino que brinda grandes posibilidades es la medicina alternativa, es decir, los fitofármacos.Peptic ulcer is one of the diseases affecting humans and causing changes in their individual and social life. It is very common in almost every country in the world. Peptic ulcer is usually associated to the consumption of non-steroidal anti-inflammatory or to Helicobacter pylori infection; hence, the drug treatment differs from one case to another. Various aspects such as the possibility of anti-ulcer drugs to interact with other active ingredients and foodstuffs, the adverse effects, the application of three or four therapies that bother the patient because of the the large number of drugs to be taken, and finally the current increased antibiotic resistance were taken into consideration. It is necessary to search for alternatives to control this disease. The alternative medicine, i.e. the herbal medicine offers new possibilities of treatment.

    Full Text Available Este trabajo realiza una estadística de la frecuencia de las nevadas ocurridas sobre el sudeste de la provincia de Buenos Aires durante un período de 35 años (1960-2004. Utilizando información de tiempo presente se detectaron 32 eventos de nevada, 7 de los cuales produjeron nieve en más de una estación sinóptica. A fin de comprender los patrones de circulación, se realiza una climatología sinóptica de las incursiones de aire frío que son responsables de nevadas en la región de estudio. Dichos patrones se caracterizan por anomalías extremas en las vaguadas asociadas a frentes fríos y en las cuñas posfrontales que denotan la intensidad de dichos sistemas. El campo de anomalías de altura geopotencial muestra en los casos de nieve generalizada un mínimo sobre la vaguada frontal que duplica la intensidad de la obtenida en los casos de nieve aislada. El intenso régimen ciclónico favorece la convergencia en niveles bajos y el fuerte enfriamiento, evidente en las anomalías del campo térmico en niveles medios, indicando la inestabilidad generada en la masa de aire que es conducida hacia el norte sobre la costa patagónica y el Mar Argentino. En un caso particular de nevada generalizada, asociada a una fuerte incursión de aire frío ocurrida el 10 de julio de 2004 sobre el sudeste de la costa bonaerense, se analiza la situación sinóptica utilizando el modelo "Sistema de Modelado Atmosférico Regional" (RAMS como herramienta de diagnóstico y se la relaciona con las muestras previamente encontradas, caracterizando la masa de aire polar y su evolución. La nevada se asocia a una inestabilización sostenida de la masa de aire, favorecida por calentamiento y humedecimiento en una trayectoria dominantemente marítima y por convergencia en un régimen ciclónico en niveles bajos.This paper presents a statistic of the frequency of snow-fall occurred over the southeast of Buenos Aires province over a 35 year period (1960-2004.

    Full Text Available A alimentação saudável e diversificada é essencial para a manutenção da saúde física e mental, e apesar de o perfil alimentar atual valorizar a praticidade do comer, nota-se que a população está consumindo, de forma crescente, frutas, tanto na forma in natura como na forma de sucos. No entanto, o consumo de certas frutas in natura ocorre acompanhado da ingestão de suas sementes, cascas ou mesmo outras partes, podendo existir fatores antinutricionais, moléculas e/ou compostos que podem interferir na biodisponibilidade e/ou digestibilidade de nutrientes, tais como os inibidores de tripsina. Tais inibidores podem prejudicar o aproveitamento de proteínas presentes nos alimentos, porém estudos recentes vêm sendo divulgados, demonstrando também os efeitos benéficos dos mesmos. Este estudo teve como objetivo avaliar inibidores de tripsina nos extratos aquosos das frutas: goiaba (Psidium guajava L, das variedades Kumagai (branca e Paluma (vermelha; maracujá-amarelo (Passiflora edulis f. e melancia (Citrullus vulgaris Schrad. Para tal, foi realizada a detecção da presença da atividade antitríptica e a dosagem de proteínas solúveis. Em todos os extratos analisados, foi detectada atividade inibitória de tripsina, bem como de proteínas solúveis. Assim, a inibição pode ser explicada pela presença de inibidores proteicos, pois, nos extratos de sementes, em SDS-PAGE, foi possível visualizar um largo espectro de bandas proteicas. Vale ressaltar que, no estudo, as bandas proteicas que coincidem com as massas moleculares dos inibidores de tripsina não apareceram de forma majoritária, demonstrando que os extratos de sementes, provavelmente, possuem inibidor proteico, no entanto em pouca quantidade, justificando a baixa atividade antitríptica (1,36 a 15,15 UI / mg de peso seco, também apresentada pelos extratos de polpa. Portanto, tendo em vista o consumo recomendado das frutas, incluindo goiaba, maracujá e melancia

In these eyes the retinal layers were not well differentiated. Foveal depression was clearly evident in 23%. CONCLUSIONS: In premature patients with retinopathy of prematurity, optical coherence tomography revealed poorly differentiated layers in the macular region with increased reflectivity in retinal pigmented epithelial-choriocapillaris zone.OBJETIVO: Descrever os aspectos morfológicos da mácula em pacientes com retinopatia da prematuridade (ROP. MÉTODOS: Doze pacientes com retinopatia da prematuridade graus I, II and III foram submetidos a mapeamento de retina e avaliação por tomografia de coerência óptica. RESULTADOS: Em todos os treze olhos de 12 pacientes a tomografia de coerência óptica mostrou a camada do epitélio pigmentar hiperrefletiva, sendo a área macular com maior intensidade. Nesses olhos as camadas da retina não estavam totalmente diferenciadas. A depressão foveal ficou claramente evidente pela tomografia de coerência óptica em 23%. CONCLUSÃO: Nos pacientes prematuros com retinopatia da prematuridade, a tomografia de coerência óptica mostrou as camadas da retina pouco diferenciadas com aumento da refletividade na área macular do complexo epitélio retiniano pigmentar-coriocapilar.

    The present states of nuclear power in Spain is shortly surveyed. Data are provided on NPPs currently in operation, under construction, designed and planned. In line with the 10-year ''National programme of electricity supply'' a major and all increasing part of the electricity generation growth is to be ensured by NPPs and to account for more than 50% by the end of the period (1987). Out of the 7 units of NPPs now under construction, 6 units utilize PWR reactors and only 1 unit- a BWR reactor. The roles of private and public sectors are noted. Main characteristics of the ''ENSA'' plant now under construction are provided where components of NPPs with PWR and BWR reactors will be fabricated. Major developments in the fields of mining, milling and extraction of U from lignites, U enrichment, fuel fabrication and spent fuel reprocessing are considered. Measures now taken to improve the licensing procedure, surveillance of NPPs and personnel training are to advance the nuclear power development programme in the country

    Assessing the demand for radiotherapy in Spain based on existing evidence to estimate the human resources and equipment needed so that every person in Spain has access to high-quality radiotherapy when they need it. We used data from the European Cancer Observatory on the estimated incidence of cancer in Spain in 2012, along with the evidence-based indications for radiotherapy developed by the Australian CCORE project, to obtain an optimal radiotherapy utilisation proportion (OUP) for each tumour. About 50.5 % of new cancers in Spain require radiotherapy at least once over the course of the disease. Additional demand for these services comes from reradiation therapy and non-melanoma skin cancer. Approximately, 25-30 % of cancer patients with an indication for radiotherapy do not receive it due to factors that include access, patient preference, familiarity with the treatment among physicians, and especially resource shortages, all of which contribute to its underutilisation. Radiotherapy is underused in Spain. The increasing incidence of cancer expected over the next decade and the greater frequency of reradiations necessitate the incorporation of radiotherapy demand into need-based calculations for cancer services planning.

    The FSC workshop in Spain provided an important opportunity to carry out an in-depth examination of decision-making processes undertaken in an NEA member country, and to reflect on the evolution that has taken place over time. It offered a well-rounded perspective on the inclusion of stakeholders in decision making, and the atmosphere of the meetings was conducive to an honest and open exchange of ideas. The workshop started with the introduction of two case studies: the earlier attempt in Spain to locate a potential site for a high-level waste (HLW) disposal facility, and the dismantling of the Vandellos-I nuclear power plant. This was followed by two days of presentations and round-table discussions based on the recent COWAM Spain initiative (stemming from the EU-wide project on Community Waste Management), which aims at developing recommendations for institutional arrangements and decision-making processes concerning the siting of waste management facilities in Spain. This article provides a brief summary of the case studies and the COWAM Spain initiative, followed by some of the lessons learnt from an international perspective. (authors)

  5. Spain: Success story in space

    Longdon, Norman

    From the early 1960's, European governments were aware that they had to take part in the exploration, and potential exploitation, of space, or be left behind in a field of high-technology that had far-reaching possibilities. It was also realized that financial and manpower constraints would limit the extent to which individual nations could carry out their own national programs. They, therefor, joined forces in two organizations: the European Space Research Organization (ESRO) and the European Launcher Development Organization (ELDO). By 1975, when the potential of space development had been more fully appreciated, the two organizations were merged into the Europeans Space Agency (ESA) of which Spain was a founding member. ESA looks after the interest of 13 member states, one associated member state (Finland), and one cooperating state (Canada) in the peaceful uses of space. Its programs center around a mandatory core of technological research and space science to which member states contribute on the basis of their Gross National Product. Spain in 1992 contributes 6.46% to this mandatory program budget. The member states then have the chance to join optional programs that include telecommunications, observation of the earth and its environment, space transportation systems, microgravity research, and participation in the European contribution to the International Space Station Freedom. Each government decides whether it is in its interest to join a particular optional program, and the percentage that it wishes to contribute to the budget. Although in the early days of ESA, Spain participated in only a few optional programs, today Spain makes a significant contribution to nearly all of ESA's optional programs. This document presents Spain's contributions to particular ESA Programs and discusses Spain's future involvement in ESA.

    Full Text Available La apertura de los canales de glutamato tipo NMDA, gracias a la acción concomitante de las neuronas pre-sináptica y post-sináptica a nivel de las espinas dendríticas, induce a modificaciones de la fuerza y eficacia sinápticas en éstas, fenómeno mejor conocido como plasticidad sináptica. Las dos formas conocidas de plasticidad sinápticas son la potenciación a largo plazo (LTP y la depresión a largo plazo (LTD. Subyacen a ambos tipos de plasticidad modificaciones covalentes sobre las distintas proteínas que componen la densidad post-sináptica y, en caso de que la LTP se prolongue, una regulación activa de la transcripción y traducción de material genético. Así, la regulación activa de la fuerza y eficacia sináptica se debe al control activo sobre la tasa de inserción y remoción de los receptores de glutamato tipo AMPA, receptores encargados de la excitación rápida en el cerebro. Lo significativo de dicho evento en el hipocampo se debe a que éste está relacionado de manera estrecha con la memoria declarativa de los individuos, su memoria de reconocimiento y la memoria espacial, esta última mediada por la activación precisa y coordinada de las células de lugar que se encuentran en él.

Through this initiative NCAM s people work together with government, industry, and academia to ensure the technology base and national infrastructure are available to develop innovative manufacturing technologies with broad application to NASA Enterprise programs, and U.S. industry. Educational enhancements are ever-present within the NCAM focus to promote research, to inspire participation and to support education and training in manufacturing. Many important accomplishments took place during 2002. Through NCAM, NASA was among five federal agencies involved in manufacturing research and development (R&D) to launch a major effort to exchange information and cooperate directly to enhance the payoffs from federal investments. The Government Agencies Technology Exchange in Manufacturing (GATE-M) is the only active effort to specifically and comprehensively address manufacturing R&D across the federal government. Participating agencies include the departments of Commerce (represented by the National Institute of Standards and Technology), Defense, and Energy, as well as the National Science Foundation and NASA. MSFC s ongoing partnership with the State of Louisiana, the University of New Orleans, and Lockheed Martin Corporation at the Michoud Assembly Facility (MAF) progressed significantly. Major capital investments were initiated for world-class equipment additions including a universal friction stir welding system, composite fiber placement machine, five-axis machining center, and ten-axis laser ultrasonic nondestructive test system. The NCAM consortium of five universities led by University of New Orleans with Mississippi State University, Tennessee Technological University, Texas A&M University, and Virginia Polytechnic Institute and State University provided wide-ranging engineering research, new degree/curriculum programs, and a web-based lecture series. NCAM has fostered an important presence and leadership role within the national manufacturing community. Its progressive influence can be seen in government, industry and academia, and in national associations, professional organizations, conferences, workshops, and forums.

    Periodic cancer incidence estimates of Spain from all existing population-based cancer registries at any given time are required. The objective of this study was to present the current situation of cancer incidence in Spain. The Spanish Network of Cancer Registries (REDECAN) estimated the numbers of new cancer cases occurred in Spain in 2015 by applying the incidence-mortality ratios method. In the calculus, incidence data from population-based cancer registries and mortality data of all Spain were used. In 2015, nearly a quarter of a million new invasive cancer cases were diagnosed in Spain, almost 149,000 in men (60.0%) and 99,000 in women. Globally, the five most common cancers were those of colon-rectum, prostate, lung, breast and urinary bladder. By gender, the four most common cancers in men were those of prostate (22.4%), colon-rectum (16.6%), lung (15.1%) and urinary bladder (11.7%). In women, the most common ones were those of breast (28.0%), colon-rectum (16.9%), corpus uteri (6.2%) and lung (6.0%). In recent years, cancer incidence in men seems to have stabilized due to the fact that the decrease in tobacco-related cancers compensates for the increase in other types of cancer like those of colon and prostate. In women, despite the stabilization of breast cancer incidence, increased incidence is due, above all, to the rise of colorectal and tobacco-related cancers. To reduce these incident cancer cases, improvement of smoking control policies and extension of colorectal cancer screening should be the two priorities in cancer prevention for the next years.

    Full Text Available The aim of this study was to evaluate the frequency of epilepsy in patients who presented psychogenic non-epileptic seizures (PNES. The evaluation was carried out during intensive VEEG monitoring in a diagnostic center for epilepsy in a university hospital. The difficulties involved in reaching this diagnosis are discussed. Ninety-eight patients underwent intensive and prolonged video-electroencephalographic (VEEG monitoring; out of these, a total of 28 patients presented PNES during monitoring. Epilepsy was defined as present when the patient presented epileptic seizures during VEEG monitoring or when, although not presenting epileptic seizures during monitoring, the patient presented unequivocal interictal epileptiform discharges. The frequency of epilepsy in patients with PNES was 50% (14 patients. Our findings suggest that the frequency of epilepsy in patients with PNES is much higher than that of previous studies, and point out the need, at least in some cases, for prolonging the evaluation of patients with PNES who have clinical histories indicating epilepsy.O objetivo deste estudo foi avaliar a frequência de epilepsia em pacientes que apresentaram crises não epilépticas psicogênicas (CNEP.

Realizamos uma revisão da literatura, selecionando artigos nas bases de dados Medline e Bireme, a partir dos unitermos: "non-epileptic seizures", "psychogenic seizures". As crises não-epilépticas (CNE podem ser classificadas em fisiológicas (síncope, migrânea, ataque isquêmico transitório e em psicogênicas (voluntárias ou não. O padrão-ouro para a diferenciação entre as crises epilépticas e as CNE é o videoeletroencefalograma, mas vários dados semiológicos podem auxiliar esse processo. O tratamento das CNE baseia-se em psicoterapia e em farmacoterapia direcionadas aos transtornos psiquiátricos comórbidos. Apesar de a alta prevalência das CNE e de sua elevada morbidade, são escassos os estudos na literatura nacional. São muitos os desafios diagnósticos e terapêuticos.

Descrever os achados epidemiológicos, clínicos e liquóricos dos casos de meningite asséptica associada à vacina tríplice viral (sarampo, caxumba e rubéola, ocorridos no Estado da Bahia após campanha de vacinação em massa promovida pelo Ministério da Saúde do Brasil em agosto de 1997, e comparar esses casos aos de meningite asséptica não associada à vacina ocorridos no mesmo ano. Métodos. Entre março e outubro de 1997, foi realizado acompanhamento prospectivo de todos os indivíduos com idade de 1 a 12 anos admitidos no Hospital Couto Maia com diagnóstico clínico e laboratorial de meningite asséptica. A população do estudo foi dividida em dois grupos, representando indivíduos vacinados e não vacinados. Foram coletadas informações demográficas, clínicas e laboratoriais para ambos os grupos. Resultados. No mês de setembro, logo após a campanha de vacinação, 74 casos de meningite asséptica foram atendidos no Hospital Couto Maia, em comparação com a média mensal de 7,5 casos. Verificamos maior freqüência de rigidez de nuca e níveis mais altos de celularidade liquórica nas crianças cuja meningite foi associada à vacina. Por outro lado, houve maior número de casos com comprometimento encefálico no grupo de meningites não associadas à vacinação. Conclusões. Embora a meningite pós-vacinal tenha curso mais benigno, seu tratamento continua gerando custos com exames complementares e internações. As campanhas de vacinação em larga escala devem utilizar vacinas contendo cepas menos reatogênicas.

    1994-01-01

    Since Spain's entry into the European Community a liberalisation of the oil industry has occurred culminating in two oil sector reform laws passed in 1992. While competition has increased, a return to the free-market policies which held sway before 1927 has not happened. Rather, three large companies dominate the Spanish oil market, with continuing input from government towards liberalization, if somewhat slowly. This paper describes recent changes and examines factors which limit liberalization policies. (UK)

    2008-01-01

    This paper analyzed industrial accidents that take place on construction sites and their severity. Eighteen variables were studied. We analyzed the influence of each of these with respect to the severity and fatality of the accident. This descriptive analysis was grounded in 1,630,452 accidents, representing the total number of accidents suffered by workers in the construction sector in Spain over the period 1990-2000. It was shown that age, type of contract, time of accident, length of service in the company, company size, day of the week, and the remainder of the variables under analysis influenced the seriousness of the accident. IMPACT ON INJURY PREVENTION: The results obtained show that different training was needed, depending on the severity of accidents, for different age, length of service in the company, organization of work, and time when workers work. The research provides an insight to the likely causes of construction injuries in Spain. As a result of the analysis, industries and governmental agencies in Spain can start to provide appropriate strategies and training to the construction workers.

Tais aspectos são relevantes na hora do aluno desenvolver uma visão mais adequada na sua compreensão de como uma teoria ou modelo é construído. Além disso, as abordagens mais tradicionais, também, já não garantem a aprendizagem de teorias físicas. Com a inserção de discussões, que envolvam a História e a Filosofia da Ciência (HFC, os alunos poderão vivenciar o desenvolvimentos de teorias físicas e, também, realizar estudos sobre a natureza da ciência, colocando em evidência aspectos não abordados nas práticas mais tradiconais. Este estudo é baseado em uma pesquisa bibliográfica, que contempla a história da óptica, e, em especial, a controvérsia existente em relação a natureza da luz com destaque a influência newtoniana para a aceitação da teoria corpuscular no século XVIII.

    Full Text Available La artritis séptica de pubis u osteomielitis púbica es la infección que compromete la sínfisis pubiana y su articulación. Es poco frecuente, representando menos del 1% de las osteomielitis. Afecta más a menudo a atletas jóvenes y a mujeres que se someten a cirugía ginecológica o urológica. Se presenta con fiebre y dolor púbico, irradiado a genitales, que aumenta con la movilización de la cadera lo que produce claudicación de la marcha. Debe hacerse el diagnóstico diferencial con la osteítis del pubis que es una condición inflamatoria estéril. La punción guiada por imagen suele ser necesaria para el diagnóstico diferencial con la osteítis del pubis. El diagnóstico se basa en la clínica apoyada en el aislamiento microbiológico, métodos por imágenes e incremento de las proteínas de fase aguda. Los agentes etiológicos más comúnmente encontrados son Staphylococcus aureus, seguidos de bacilos gram negativos, o pueden ser polimicrobianos en posquirúrgicos. El tratamiento antibiótico se ajusta al germen aislado por cultivo, además de antiinflamatorios y reposo. El desbridamiento quirúrgico se requiere hasta en el 55% de los casos. Se recomiendan antibióticos por 6 semanas. Se presentan dos casos de osteomielitis del pubis por S. aureus, con buena respuesta al tratamiento. Ambos pacientes eran jóvenes y deportistas.Septic arthritis of the pubic symphysis, so called osteomyelitis pubis is the infection which involves pubic symphysis and its joint. It is a rare condition, representing less than one percent of all cases of osteomyelitis. It affects most frequently young athletes and women undergoing gynecologic or urologic surgery. It presents itself with fever and pubic pain which irradiates to the genitals and increases when hip is mobilized, and this fact produces gait claudication. Differential diagnosis should be made with pubic osteitis, which is a sterile inflammatory condition. Diagnosis is based on clinic

    Full Text Available La impregnación neuroléptica es un trastorno causado por los efectos adversos del tratamiento terapéutico con neurolépticos, que provocan en ciertos pacientes una variedad de efectos secundarios, que al ser identificados obligan a reducir las dosis o emplear otros medicamentos para controlarlos, pero, si no son hallados a tiempo sus síntomas se acentúan hasta llegar a ser un síndrome neuroléptico maligno, el cual es altamente mortal. La presente investigación está enfocada a plantear los diagnósticos e intervenciones en el correcto manejo de este trastorno, observando que el personal de enfermería del hospital mental no dispone de un plan de cuidados que incluya la valoración diagnóstica de enfermería y por tal motivo no se lleva a cabo un tratamiento terapéutico apropiado. Con los resultados obtenidos, se encontró que es más frecuente en el género masculino, ya que es la patología en la que más se presenta como es el trastorno psicótico agudo. Los neurolépticos más utilizados en los pacientes con impregnación neuroléptica son el haloperidol y el sinogan; y los efectos adversos se presentan con mayor frecuencia después de 0-13 días de tener instaurado un tratamiento farmacológico con neurolépticos. Las actividades realizadas por el personal de enfermería del Hospital Mental Rudesindo Soto con los pacientes que presentan impregnación neuroléptica, son en la mayoría de los casos la administración del medicamento antagonista y con menor frecuencia la suspensión del neuroléptico, administración de dieta liquida y blanda. Los signos y síntomas más frecuentes son la rigidez muscular, confusión y disfagia. Se encontraron dieciséis diagnósticos de enfermería prevalentes de los cuales se eligieron seis prioritarios para intervenir.

  11. Spain. Women in the world.

    Galindo, E; Serrano, N

    1994-08-01

    Spanish women live almost 2 times longer today than did their great grandmothers (60-65 years vs. 35). Contraception is more accessible, resulting in fewer pregnancies and their complications. The National Health Service of Spain provides women and their families medical care. Yet, women's health risks continue. Class, race, and geography result in women having uneven access to medical care. Primary health care services are not a priority as are high- technology hospitals. Women, who already lead a busy life, still care for older people or people with disabilities. Many households have a very limited or no income and depend on welfare benefits or family. There are more women than men who are poor because women, many of whom are single, are raising large families and many live alone. Women are often the victims of violence and of domestic abuse (1993, 86 violent deaths and 200,000 cases of abuse by a partner). Spain has laws that protect women facing divorce and that allow abortion, but men have created the world order. Women suffer daily in a world which does not recognize rape and sexual harassment as war crimes (e.g., former Yugoslavia). In Seville, the Solidarity Network of Women in Black is a pacifist group working to stop violence. They plan on setting up links to publicly denounce and act against all aggression and to institutionalize women's right to full freedom. War is destroying women's lives.

    The purpose of this paper is to study the problems raised in Spain by third party liability insurance for nuclear damage. National law in this field is based on the Paris Convention on nuclear third party liability and defines the conditions of liability of operators of nuclear installations. The insurance contract requirements must comply with the regulations on cover for nuclear risks, under the control of the Finance Ministry's competent services. Certain exceptional nuclear risks which cannot be covered entirely by ordinary insurance policies, are taken over by the Consorcio de Compensacion de Seguros which belongs to this Ministry. From the insurance viewpoint, the regulations make a distinction between nuclear and radioactive installations and nuclear transport. (NEA) [fr

    1976-01-01

    The paper presents a review of the Spanish needs of uranium concentrates and uranium ore processing technology and trends in Spain. Spain produces approximately 200t U 3 O 8 /a at two facilities. One plant in the south (Andujar, Jaen) can obtain 70t U 3 O 8 /a and uses a conventional acid leaching process with countercurrent solvent extraction. A second plant, situated in the west (Ciudad Rodrigo, Salamanca) has started in 1975 and has a capacity of 120-130t U 3 O 8 /a, using acid heap leaching and solvent extraction. There is another experimental facility (Don Benito, Badajoz) scheduled to start in 1976 and expected to produce about 25-35t U 3 O 8 /a as a by-product of the research work. For the near future (1978) it is hoped to increase the production with: (a) A new conventional acid leaching/solvent extraction plant in Ciudad Rodrigo; its tentative capacity is fixed at 550t U 3 O 8 /a. (b) A facility in the south, to recover about 130t U 3 O 8 /a from phosphoric acid. (c) Several small mobile plants (30t U 3 O 8 /a per plant); these will be placed near small and isolated mines. The next production increase (1979-1980) will come with the treatment of sandstones (Guadalajara and Cataluna) and lignites(Cataluna); this is being studied. There are also research programmes to study the recovery of uranium from low-grade ores (heap, in-situ and bacterial leaching) and from other industries. (author)

    This paper analyzes organizational and marketing changes occurring in Spain's oil industry as a result of its conversion from a state run monopoly system to a free market system. The analysis uses statistical data to indicate national oil production, import and consumption trends and compares these with overall trends in the European Communities. An explanation of the way in which oil is marketed in Spain makes reference to data on Spain's refining capacity and pipeline network, deemed to be amongst the most complete and modern in Europe. Comments are also made on the efficacy of Spain's national energy policies which stress energy source diversification to lessen this country's heavy dependence on foreign supplied oil

    Full Text Available Several demyelinating disorders can affect children. The differential diagnosis between these diseases is usually an arduous task. Diagnostic criteria have been proposed for some of these disorders, however most of them have not yet been clinically and prospectively validated. Here we present a case of a ten year-old boy with recurrent bilateral optic neuritis and spinal cord involvement. Clinical and cerebrospinal fluid data have fulfilled diagnostic criteria for Devic's neuromyelitis optica (NMO. The differential diagnosis with multiple sclerosis (MS has become troublesome since not only optic nerves and spinal cord were involved. In one of the relapses a left hemiparesis with facial involvement was registered. Magnetic resonance imaging was also compatible with MS. This case illustrates that CNS demyelinating disorders can fulfill diagnostic criteria for more than one demyelinating disease, making the clinical judgment an important tool in the management of these patients.Diversas doenças desmielinizantes podem ocorrer em crianças, sendo muitas vezes o diagnóstico diferencial entre elas difícil. Critérios diagnósticos têm sido propostos para algumas destas entidades, entretanto nenhum deles pode ser considerado definitivo. O objetivo deste trabalho é apresentar o caso de um paciente de 10 anos de idade, com quadro recorrente de neurite óptica bilateral e mielopatia. Os dados clínicos e liquóricos preencheram critérios para o diagnóstico de neuromielite óptica de Devic. O diagnóstico diferencial foi especialmente difícil em relação à esclerose múltipla, pois não apenas os nervos ópticos e medula foram acometidos, visto que em um dos surtos registrou-se hemiparesia, com acometimento facial. A ressonância magnética foi também compatível com esclerose múltipla. Este caso ilustra que pacientes com doenças desmielinizantes do SNC podem preencher critérios diagnósticos para mais de uma delas, o que torna o julgamento cl

    Full Text Available Since the restoration of democracy, Spain’s successive governments have been noted for their favourable stance toward the issue of Palestine and their support for the creation of a sovereign independent state in the territories that Israel occupied during the Six-Day War. Yasser Arafat’s visit to Spain in the time of the UCD, the holding of the Madrid Conference during the term of government of the PSOE and the designation of Miguel Ángel Moratinos as the EU’s special envoy for the Peace Process during the Partido Popular’s term of government are some of the landmarks that have expressed this exemplary relationship between the Spanish State and the Palestine question. However, the victory of Hamas in the legislative elections of 25 January 2006 radically changed the situation, as it led to Rodríguez Zapatero’s government joining the international boycott of the new Islamist executive; even so, the Spanish government clearly maintained its support for restarting the Peace Process, in the form of its backing for Mahmud Abbas, the President of the Palestine Authority. The armed conflict in Gaza in June 2007 which led to the Islamists retaking the Gaza Strip and the formation of a new government in the West Bank led by the technocrat Salam Fayad served to normalise the situation, given that it encouraged the raising of international sanctions and a return to normality in Spanish-Palestine relations.

    1994-01-01

    The experience obtained from the in-service inspection of reactor pressure vessels (RPV) of Spanish nuclear power plants and the participation in several international programs, such as PISC, has shown the need for a performance demonstration, not only for the ultrasonic inspection techniques of RPV, but also for other ISI non-destructive techniques as in the case of eddy current inspection of steam generator tubing. Section XI of the ASME Code, which is applied in Spain for ISI, has incorporated recently the Appendix VIII for performance demonstration of ultrasonic inspection techniques. As a direct consequence of this, a Spanish project for performance demonstration of ultrasonic inspection techniques has been launched recently, which includes the manufacturing of full-scale mock-ups of nozzle to vessel welds, reactor vessel welds, wrought austenitic piping welds and ferritic piping welds of PWR and BWR nuclear power plants from different suppliers. This considerable technical effort will let the different Spanish organizations which are part of the project to participate and colaborate with similar international projects and in particular with a European initiative for performance demonstration.

    For three decades, and after the entry of Spain into the EU, it has been developed a regulatory, stable but evolving, framework that has allowed to create the conditions and structures to have stringent safety conditions of products and manufacturing facilities, as well as all the activities necessary for their certification and control. This development has been possible, among others, by the work of impulse and coordination of the Ministry of industry, Energy and Tourism, and particularly of the quality and Industrial safety sub directorate. On the other hand it has been developed a quality infrastructure that has, at the State level, with a standardisation (AENOR) entity and an accreditation body (ENAC) with recognized prestige around the world. In this article, in the first part, a list the regulations which apply to products and manufacturing facilities is shown, as well as explain the role played by standards and accreditation system in industrial safety and the factor of competitiveness that this entails for our industrial sector, and, in the second part, the institutional role of the Ministry and, the aforementioned Sub directorate, is described. The aim of the article is to be a descriptive reference of the current regulatory framework as well as the role of the State in this process. (Author)

  1. Climate index for Spain - Methodology

    2006-01-01

    According to the U.S. Department of Energy, an estimated 25% of the GNP is affected by weather-related events. The variations in temperature - even small ones - can also have long-lasting effects on the operational results of a company. Among other, the Energy supply sector is sensitive to weather risks: a milder or harsher than usual winter leads to a decrease or increase of energy consumption. The price of electricity on power trading facilities like Powernext is especially sensitive to odd changes in temperatures. Powernext and Meteo-France (the French meteorological agency) have joined expertise in order to promote the use of weather indices in term of decision making or underlying of hedging tools to energy actors, end users from any other sector of activity and specialists of the weather risk hedging. The Powernext Weather indices are made from information collected by Meteo-France's main observation network according to the norms of international meteorology, in areas carefully selected. The gross data are submitted to a thorough review allowing the correction of abnormalities and the reconstitution of missing data. Each index is fashioned to take into account the economic activity in the various regions of the country as represented by each region's population. This demographic information represents a fair approximation of the weight of the regional economic activity. This document presents the calculation methodology of average, minimum and maximum weather indexes with the winter and summer regression equations for the different economical regions of Spain.

    The Empresa Nacional del Uranio, SA (ENUSA) was founded in 1972 to undertake and develop the industrial and procurement activities of the nuclear fuel cycle in Spain. Within the organisation of ENUSA, the Uranium Division is directly responsible for the uranium mining and production operations that have been carried out since 1973 in the area of Ciudad Rodrigo in the province of Salamanca. These activities are based on open pit mining, heap leaching and a hydrometallurgical plant (Elefante) for extracting uranium concentrates from the ore. This plant was shut down in 1993 and a new plant was started up on the same site (Quercus) with a dynamic leaching process. The nominal capacity of the new plant is 950 t U 3 O 8 per year. Because of the historically low uranium prices which have recently prevailed, the plant is currently running at a strategic production rate of 300 t U 3 O 8 per year. From 1981 to 1990, in the area of La Haba (Badajoz province), ENUSA also operated a uranium production site, based on open pit mining, and an experimental extraction plant (Lobo-G). ENUSA is currently decommissioning these installations. This paper describes innovations and improvements that ENUSA has recently introduced in the field of uranium concentrates production with a view to cutting production costs, and to improving the decommissioning and site restoration processes in those sites where production is being shut down or resources have been worked out.

  1. Tarasca: ritual monster of Spain.

    Science.gov (United States)

    Gilmore, David D

    2008-09-01

    Let us now revisit our original assumptions. First, we note that for the participants in Hacinas Carnival the Tarasca is a figure of fun and joy, but it also exudes a strain of aggressive misogyny that many female residents, not to mention tourists, find somewhat unsettling. In the spirit of feminist currents in Spain, a group of young women protested in 1992 to town officials and, when rebuffed, sought to build their own female monster, which they intended to use to attack boys and men. While their plan was never carried out, and indeed met with stiff opposition from officialdom and, especially, from older women, some of the younger, more modern girls find the Tarasca appalling, and they told me so without compunction. Accordingly, today the festival tends to polarize the sexes as well as the generations. Also, many children are frightened by the gigantic mock-up with its snapping teeth and foul breath, and many of them burst into tears at the roaring of the demons. But despite these negatives--or perhaps because of them--the Tarasca breaks down boundaries between things normally kept separate in the mind: humor and terror, man and beast, order and disorder, old and young, life and death, and so on. In so collapsing opposites, the Tarasca causes people to pause and to think about and question everyday reality in the non-Carnival universe. All these observations of course support the structural arguments of our four theorists above and in particular seem to corroborate Bloch's concept (1992) of the regenerative power of "rebounding violence." However, there are three specific features here that need psychological amplification beyond simply confirming the work of previous theorists. We must first note that like most grotesque fantasies, the Hacinas monster combines disparate organic "realities" into a bizarre and monstrous image that by its very oddness and the resulting "cognitive mismatch" captures people's attention and sparks the imagination, especially that of

    Full Text Available La investigación se realizó en la Estación Experimental de Pastos y Forrajes "Indio Hatuey", con el objetivo de determinar las características organolépticas y físico-químicas de la miel producida por Melipona beecheii. Para la extracción y el envasado de la miel se utilizaron jeringuillas estériles y frascos secos esterilizados, debidamente etiquetados. Después, se detectó en la muestra la presencia de granos de polen pertenecientes a Gliricidia sepium, y se realizó un análisis sensorial y físico-químico basado en los siguientes indicadores: aspecto, color, olor, sabor, textura, humedad (g/100 g, acidez libre (meq/100 g, pH y sólidos solubles (g/100 g = %. Además, se realizaron determinaciones cromatográficas de los azúcares presentes. Los valores de pH estuvieron alrededor de 3,6; la acidez libre fue de 35,0 meq/100 g, y la humedad, de 24 %. Por su parte, el análisis sensorial estuvo acorde con las especificaciones de calidad recomendadas en la norma de calidad cubana, ya que la miel no presentó ningún sabor, aroma o color desagradables. Se concluye que la miel de M. beecheii presentó una excelente calidad, al no sufrir ningún proceso de degradación aparente; por ello se puede considerar como una miel fresca, lo que constituye un requisito clave para cualquier alimento destinado al consumo humano.

    Full Text Available Fatty acidic composition, organoleptic characteristics and other quality parameters of virgin olive oils were evaluated in dry-farming and irrigated olive orchards. The acidic composition was affected by irrigation. The content in monoinsaturated and polunsaturated fatty acid was higher in the oils of the dry-farming olive orchard, while the relative content in saturated fatty acids was higher in the irrigated one. The insaturated/ saturated and oleic/linoleic relations distinguish the irrigated and non irrigated olive trees. The K225 values, the poliphenolic contents and the bitter taste were also correlated. The oils from non irrigated olive trees showed the higher bitter taste. Those three parameters discriminated the oils from irrigated and non irrigated trees. The bitter taste diminished when increasing the amount of water supplied with the irrigation.

    Se estudia la composición relativa en ácidos grasos, características organolépticas y parámetros de calidad de los aceites producidos en olivares de secano o regados con diferentes dosis de agua. La composición acídica fue alterada por el riego. El contenido en ácidos grasos monoinsaturados y poliinsaturados fue mayor en los aceites de secano, mientras que el contenido relativo en ácidos grasos saturados fue mayor en regadío. Las relaciones insaturados/saturados y oleico/linoleico diferencian los aceites de riego y de secano. Existió una relación entre los valores de K225, el contenido en polifenoles y el grado de amargor, siendo los aceites de secano mucho más amargos que los de riego, discriminando estos tres parámetros los aceites de riego y los de secano. El grado de amargor disminuyó al aumentar la cantidad de agua aportada con el riego.

El artículo presenta el origen y la justificación de la terapia esteroidea en este grupo de enfermedad, así como los mecanismos de acción y beneficios de tratamientos más modernos como los inmunomoduladores e inmunosupresores. El trabajo también introduce muchas de las drogas con efectos neuroprotectores que se encuentran en fases experimentales, cuyo uso prevendría la neurodegeneración que se produce a nivel de las células ganglionares retinianas en esta enfermedad neurológica. Las opciones terapéuticas actuales ofrecen variantes de tratamiento adicionales a pacientes con mayores probabilidades de desarrollo de esclerosis múltiple y retrasan la aparición de un segundo brote, así como las secuelas invalidantes que esta suele originar.A bibliographic review was conducted to provide an updating of drugs used to retard the appearance of multiple sclerosis in the management of the demyelinating inflammatory optical neuropathy. Present paper shows the origin and the justification of the steroid therapy in this disease, as well as the mechanisms of action and benefits of more recent treatments, e.g. the ongoing immunomodulations and immunosuppressive ones and also to introduce many drugs in experimental phase having neuroprotection effects whose use will prevent the neurodegenerative effect produced at level of the retinal ganglion cells in this neurologic disease. The current therapeutical options offer variants of additional treatment to those patients with greater possibilities to development multiple sclerosis and retarding the appearance of a second outbreak, as well as its disabling sequelae.

    Full Text Available Películas obtenidas a partir de almidón de yuca de la variedad CM 7138 -7, nativo y modificado por hidroxipropilación, fueron sometidas a evaluaciones mecánicas, ópticas y de barrera, durante periodos de tiempo de 0, 30, 60, 90 y 120 días determinando el efecto del tiempo de almacenamiento sobre la modificación química realizada. Las películas fueron obtenidas por extrusión soplado por medio de un extrusor de tornillo simple. El material se obtuvo en tres etapas: la primera etapa fue la producción de Almidón Termoplástico (TPS con 75% de almidón, 24,5% de glicerol y 0,5% de capsaicina; en la segunda etapa, se realizó la Mezcla Binaria (MB con 68,63% de Ácido Poliláctico (PLA, 29,41% de Policaprolactona (PCL, 1,96% de anhídrido maleico y 1% de colorante y, por último se realizó la extrusión soplado de la mezcla ternaria, compuesta por 75% de TPS y 25% MB. Los cambios de algunas propiedades con respecto al tiempo, fueron más evidentes en las películas a base de almidón nativo presentando una diferencia significativa, debido al proceso de retrogradación y posiblemente a que no se formó una fase homogénea en el material y por lo tanto los componentes se distribuyeron en fases distintas y separadas.

    Full Text Available La forma como videntes e invidentes representan el espacio genera una fuente de conocimiento que nos permite estudiar nuevas alternativas para orientar procesos de aprendizaje en la movilidad y orientación de personas que carecen de visión. Este documento caracteriza el proceso de razonamiento espacial a partir del conocimiento del mapeo cognitivo y plantea una serie de antecedentes de investigación que nos llevan a comprender la representación espacial de las personas. El mapeo cognitivo, como un proceso de razonamiento espacial, nos indica cómo se movilizan los videntes e invidentes y qué información se requiere en la movilidad, lo mismo que la manera como está distribuida dicha información en el ambiente. En los invidentes estas tareas requieren del estudio de procesos de exploración háptica que utilizan órganos sensoriales paralelos –visión alternativa– para identificar la representación del ambiente. Experiencias en la formación de modelos mentales espaciales como las referidas en este escrito, señalan que la construcción de mapas cognitivos, tanto de videntes como invidentes, es una estrategia poderosa que suministra información espacial para la movilidad. Este factor interviene en el mejoramiento de las habilidades de orientación y búsqueda del camino, lo cual influye en la orientación, independencia y calidad de vida de las personas invidentes (Jacobson, 1998.

    Objetivo: El objetivo principal del presente estudio consistió en determinar la prevalencia de los cambios en la interfase vitreomacular (IVM) mediante tomografía de coherencia óptica (OCT) en la población general. En segundo lugar, se describieron otros cambios de la OCT. Métodos: Las anomalías en la IVM se diagnosticaron mediante OCT y se distribuyeron de acuerdo con la clasificación del grupo International Vitreomacular Traction Study (estudio internacional de tracción vitreomacular, IVTS, por sus siglas en inglés) y se dividieron en 3 grados según John et al. [Retina 2014;34:442-446]. Resultados: La prevalencia calculada de anomalías vitreomaculares en la población belga de ≥50 años fue del 1,17% [intervalo de confianza (IC 0,38-3,62)] en el caso de tracción vitreomacular (TVM) focal de grado 1; del 0,39% (IC 0,05-2,76) en el caso de TVM focal de grado 2; del 8,17% (IC 5,33-12,53) en el caso de adhesión vitreomacular focal; y del 17,9% (IC 13,41-23,9) en el caso de adhesión vitreomacular difusa. Conclusiones: Se presentó la prevalencia de anomalías vitreomaculares en un estudio de cohortes belga. Estos resultados concuerdan en gran medida con los datos presentados previamente sobre la prevalencia de la TVM. Un conocimiento correcto sobre la epidemiología de las alteraciones en la IVM y un diagnóstico temprano permitirán una intervención satisfactoria. © 2017 S. Karger AG, Basel.

    2016-11-01

    This paper explores the causes behind the downturn in road accidents in Spain across the last decade. Possible causes are grouped into three categories: Institutional factors (a Penalty Point System, PPS, dating from 2006), technological factors (active safety and passive safety of vehicles), and macroeconomic factors (the Great recession starting in 2008, and an increase in fuel prices during the spring of 2008). The PPS has been blessed by incumbent authorities as responsible for the decline of road fatalities in Spain. Using cointegration techniques, the GDP growth rate, the fuel price, the PPS, and technological items embedded in motor vehicles appear to be statistically significantly related with accidents. Importantly, PPS is found to be significant in reducing fatal accidents. However, PPS is not significant for non-fatal accidents. In view of these results, we conclude that road accidents in Spain are very sensitive to the business cycle, and that the PPS influenced the severity (fatality) rather than the quantity of accidents in Spain. Importantly, technological items help explain a sizable fraction in accidents downturn, their effects dating back from the end of the nineties. Copyright © 2016 Elsevier Ltd. All rights reserved.

    Immigration is a fairly recent phenomenon in Spain and there are still few scientific publications on tuberculosis (TB) and immigration. Therefore, the aim of this study is to describe the differential characteristics of TB in the immigrant population with respect to natives in Spain. Literature review of original articles written in Spanish or English and published 1998-2012 about TB among immigrant population. The articles with the key words "Tuberculosis", "immigrants" and "Spain" were included. Literature search was performed in Medline and MEDES. A total of 72,087 articles on TB were detected worldwide, 6% of them dealt with the immigration issue. Regarding Spain we found 2,917 articles representing 4% of the papers published worldwide, and in 219 (7.5%) immigration was considered. Of the 219 articles, 48% were published in Spanish journals and the 52% remaining in Anglo-Saxon journals. 93.5% of immigrants with TB were younger than 51, whereas this percentage was 64.9% in natives. Drug resistance can be seen in 7.8% of the immigrant population but in only 3.8% of natives. It was also detected that the unavailability of a health card could be a problem. Immigrants with TB were characterized by being younger and having more drug resistance and coming mostly from Latin America, Eastern Europe, Africa and Asia. It was also detected that the unavailability of a health card could be a problem.

    The studies carried out to evaluate and select a candidate site for International Thermonuclear Experimental Reactor (ITER) construction in Spain are presented in this paper. The ITER design, completed in July 2001, considered a number of technical requirements that must be fulfilled by the selected site. Several assumptions concerning the ITER site were made in order to carry on the design before final site selection. In the studies undertaken for ITER site selection in Spain, the referred technical requirements and assumptions were applied across the whole of Spain and two areas were identified as being preferential. These areas are on the Mediterranean coast and are situated in the Catalan and Valencian regions. A comparative evaluation based on technical characteristics for the concrete plots, proposed within the preferential areas, has been done. The result of these studies was the selection of a site that was deemed to be the most competitive--Vandellos (Tarragona)--and it was proposed to the European Commission for detailed studies in order to be considered as a possible European site for ITER construction. Another key factor for hosting ITER in Spain, is the licensing process. The present status is summarised in this paper

    The purpose of the present study is to describe the economic context in Spain and its impact on the health care sector and in nursing schools. The global economic crisis is affecting nursing in Spain. This study analyses and compares indicators related to health care and nursing schools among European countries. Some new strategies to cope with the challenges arising from the health care crisis are suggested. Health care costs are increasing as a result of the ageing of the Spanish population, immigration, chronicity of health problems and new medical technology. Nursing education has changed in 2010 from a 3-year diploma programme to a 4-year University degree in Nursing. This change requires new resources involving staff, facilities and equipment, all of which are lacking because of the economic crisis in Spain. The worldwide economic crisis has affected Spain more than it has other European Union (EU) countries. This global crisis has an impact on the health care sector as well on nursing schools. It is essential for nursing management to develop creative approaches to maintain cost effective patient care. New programmes and technology must be carefully evaluated in terms of cost effectiveness before being implemented. All health care professionals should be well informed and have a solid understanding of this situation.

    Full Text Available The determination of the values of the optical constants (n, refractive index and k, extinction coefficient in the visible range of both silver (Ag and tin oxide (SnO2 films is a necessary condition to predict the behaviour of a SnO2/Ag/SnO2 multilayer for low emissivity coatings, improving the visual comfort. For this purpose, thin films of Ag and SnO2 with a thickness similar to that of multilayer coatings (90 Å and 380 Å respectively were used in order to avoid the thickness dependence of the optical constants. A simulation computational program based on the matrix method was employed to estimate the values of the optical constants of these films in the visible range. It has been also determined the dependence on the wavelength of the absorption coefficient (α, as well as the value of the energy gap, and the nature of the optical transitions.

    La determinación de los valores de las constantes ópticas (n, índice de refracción y k, coeficiente de extinción en el espectro visible de películas tanto de plata (Ag como de óxido de estaño (SnO2, es una condición necesaria para predecir el comportamiento de un recubrimiento multicapa de baja emisividad con la estructura SnO2/Ag/SnO2 en relación al confort visual. Para este propósito, se han caracterizado láminas delgadas de Ag y de SnO2 con un espesor similar al que tienen en los recubrimientos multicapa (90 Å y 380 Å respectivamente, evitando así la dependencia con el espesor de las constantes ópticas. Se ha utilizado un programa informático de simulación basado en el método matricial para determinar los valores de las constantes ópticas de dichas películas en el espectro visible. Ha sido determinada asimismo la dependencia del coeficiente de absorción (α con la longitud de onda, así como el valor del ancho de banda prohibida del óxido de estaño, y la naturaleza de la transición óptica.

    La degradación de la arteria aorta se debe a malformaciones estructurales del tejido. Estas anomalías son visibles en forma de irregularidades y manchas cuando se interroga el tejido con tomografía de coherencia óptica. La delimitación de estas irregularidades es compleja debido a su carencia de forma determinada, ruido de medida y falta de definición de las fronteras. La aplicación de la matriz Hessiana de la imagen permite identificar y delimitar las anomalías de forma precisa.

    Full Text Available Tonic spasms have been most commonly associated with multiple sclerosis. To date, few reports of series of patients with neuromyelitis optica and tonic spasms have been published. Methods: We analyzed the characteristics and frequency of tonic spasms in 19 subjects with neuromyelitis optica. Data was collected using a semi-structured questionnaire for tonic spasms, by both retrospectively reviewing medical records and performing clinical assessment. Results: All patients except one developed this symptom. The main triggering factors were sudden movements and emotional factors. Spasms were commonly associated to sensory disturbances and worsened during the acute phases of the disease. Carbamazepine was most commonly used to treat the symptom and patients showed good response to the drug. Conclusions: Tonic spasms are a common clinical manifestation in patients with neuromyelitis optica.Espasmos tônicos têm sido mais frequentemente associados com esclerose múltipla. Foram publicados até agora poucos relatos de série de pacientes com neuromielite óptica e espasmos tônicos.

    2013-11-01

    Assisted reproduction is one of the health services currently being considered for possible limitation or exclusion from the public health services portfolio in Spain. One of the main reasons claimed for this is the impact on the budget for pharmaceutical expenditure. The objective of this study was to assess the significance of the pharmaceutical costs of assisted reproduction in Spain. This study focused on medical practice in Spain, and is based on the opinions of experts in assisted reproduction and the results provided by professional societies' publications. The reference year is 2012 and the setting was secondary care. We have included all existing pharmaceutical modalities for assisted reproduction, as well as the most common drug for each modality. We have considered the pharmaceutical cost per cycle for artificial insemination, in vitro fertilisation with or without intracytoplasmic sperm injection (IVF_ICSI), and cryotransfer and donated fresh oocytes reception. In Spain, artificial insemination has a pharmaceutical cost per cycle of between €69.36 and €873.79. This amounts to an average cycle cost of €364.87 for partner's sperm and €327.10 for donor sperm. The pharmaceutical cost of IVF_ICSI ranges between €278.16 and €1,902.66, giving an average cost per cycle of €1,139.65. In the case of cryotransfer and donated fresh oocytes reception, the pharmaceutical cost per cycle is between €22.61 and €58.73, yielding an average cost of €40.67. The budgetary impact of pharmaceutical expenditure for assisted reproduction in Spain for the year 2012 was estimated at €98.7 million. In Spain, the total pharmaceutical cost of assisted reproduction is substantial. According to our results, we can say that about 29% of the total pharmaceutical expenditure for assisted reproduction techniques is funded by the National Health System and the rest represents 2.4% of the total annual out-of-pocket family expenditure on drugs.

    The purpose of this paper is to present our main results from a survey carried out in Spain in the context of social risk perception. This survey is included in a broad project (PRISP) sponsored by the UE and the national Civil Protection Service, and carried out simultaneously in three countries: Spain, Italy and UK. The project combined qualitative and quantitative assessment methods, although only survey results are presented here. A random sample of 600 subjects from two different Spanish communities close to a COMAH chemical site was selected for the research. Main findings regarding, differential perception between both community populations, sex differences, and 'bias perception' of risks among others have been achieved. Main dimensions were obtained by multidimensional scaling and Factor Analysis. Dimensions reported here are similar to the usual findings from the psychometric paradigm. (authors)

    The regulation covering radioactive and nuclear installations classifies workers operating such installations as operators or supervisors. Operators are persons who, working directly under a supervisor, handle the installation operational equipment and which have a bearing on nuclear safety or protection against radiation. Supervisors are persons directing the operations of a radioactive or nuclear installation and operator activities. The study deals with the courses given in Spain which qualify operators and supervisors in industrial radioactive installations as permit holders, as well as the courses currently being run for persons engaged in the transport of radioactive materials. Spain regulations covering transport of dangerous goods are based on separate Royal Decrees dealing with road and air transport respectively

    Breast surgery is a key part of training and competency in general surgery in Spain and is a "frontier area" that can be efficiently managed by general surgeons and gynecologists. The main objective of the training process consists of the surgical treatment of breast cancer, including conservative surgery, oncoplastic and reconstructive techniques. This article analyses the current status of breast surgery training in Spain and schematically proposes potential targets of the different training programs, to improve access and training for surgeons and residents in this area, taking into account the RD 639/2014 and European regulation. The priority is to specify the level of training that should be achieved, in relation to the group of professionals involved, considering their area of competency: surgery resident, educational programs, and surgeons with special dedication to this area.

    2011-08-01

    This article presents a review of research on entrepreneurship in Spain, paying particular attention to its beginnings, nature and main focus of interest. We have developed a database based on the review of 471 works produced between 1977 and 2009, including articles published in national and international journals and dissertations (read in Spain) that allowed us to extract the following results. There is a preference for qualitative methods, conceptual contributions and the entrepreneurial process as the privileged research theme. There is also a strong focus of interest on micro and small enterprises. These characteristics of Spanish research in areas of entrepreneurship can make a distinctive contribution to international research. However, the dissemination of knowledge and inadequate strategies for international publication limit the diffusion of Spanish research in entrepreneurship. Lastly, we discuss the implications for future research.

    Patents on antibiotics were introduced in Spain in 1949. Preliminary research reveals diversification in the types of antibiotics: patents relating to penicillin were followed by those relating to streptomycin, erythromycin and tetracycline. There was also diversification in the firms that applied for patents: while Merck & Co. Incorporated and Schenley Industries Inc. were the main partners with Spanish antibiotics manufacturers in the late 1940s, this industrial space also included many others, such as Eli Lilly & Company, Abbott Laboratories, Chas. Pfizer & Co. Incorporated, and American Cyanamid Company in the mid-1970s. The introduction of these drugs in Spain adds new elements to a re-evaluation of the autarkic politics of the early years of the Franco dictatorship.

    The EurObserv'ER policy profiles give a snapshot of the renewable energy policy in the EU Member States. On October 2015, a new support scheme (the 'Regimen Retributivo Especifico') was established in Spain. The aim was to grant a specific remuneration regime for new biomass plants located in the mainland electricity system and for wind energy plants. The allocation of the referred specific remuneration regime has been done through a competitive call for tenders. A tax regulation mechanism for investments related to RESE plants is in place. There is a tax credit for solar thermal and for bio-fuels in transport. Furthermore a quota system for bio-fuels is in place. RES-E operators are entitled to grid connection, priority dispatch against the grid operator. Currently no support schemes for RES-H and C are in place in Spain

    While Spain's national tobacco control legislation prohibits smoking in many indoor public places, the law provides for an exception to the prohibition of smoking by allowing separate seating sections and ventilation options in certain public places such as bars and restaurants, hotels and airports. Accordingly, Spain's law is not aligned with Article 8 Guidelines of the World Health Organization's Framework Convention on Tobacco Control, which requires parties to ensure universal protection against secondhand smoke exposure in all enclosed public places, workplaces and on all means of public transport. Spain's law is currently being promoted by the tobacco companies in other countries as a model for smoke-free legislation. In order to prevent weakening of smoke-free laws in other countries through industry-supported exceptions, we investigated the tactics used by the tobacco companies before the implementation of the new law and assessed the consequences of these actions in the hospitality sector. Internal tobacco industry documents made public through US litigation settlements dating back to the 1980s were searched in 2008-9. Documents show that tobacco companies sought to protect hospitality venues from smoking restrictions by promoting separate seating for smokers and ineffective ventilation technologies, supporting an unenforceable voluntary agreement between the Madrid local government and the hospitality industry, influencing ventilation standards setting and manipulating Spanish media. The Spanish National Assembly should adopt comprehensive smoke-free legislation that does not accommodate the interests of the tobacco industry. In doing so, Spain's smoke-free public places law would be better aligned with the Framework Convention on Tobacco Control.

    Although highly prevalent throughout the world, the accurate prevalence of hemoglobinopathies in Spain is unknown. This study presents data on the national registry of hemoglobinopathies of patients with thalassemia major (TM), thalassemia intermedia (TI), and sickle cell disease (SCD) in Spain created in 2014. Fifty centers reported cases retrospectively. Data were registered from neonatal screening or from the first contact at diagnosis until last follow-up or death. Data of the 715 eligible patients were collected: 615 SCD (497 SS, 64 SC, 54 SBeta phenotypes), 73 thalassemia, 9 CC phenotype, and 18 other variants. Most of the SCD patients were born in Spain (65%), and 51% of these were diagnosed at newborn screening. Median age at the first diagnosis was 0.4 years for thalassemia and 1.0 years for SCD. The estimated incidence was 0.002 thalassemia cases and 0.03 SCD cases/1,000 live births. Median age was 8.9 years (0.2-33.7) for thalassemia and 8.1 years (0.2-32.8) for SCD patients. Stroke was registered in 16 SCD cases. Transplantation was performed in 43 TM and 23 SCD patients at a median age of 5.2 and 7.8 years, respectively. Twenty-one patients died (3 TM, 17 SCD, 1 CC) and 200 were lost to follow-up. Causes of death were related to transplantation in three patients with TM and three patients with SCD. Death did not seem to be associated with SCD in six patients, but nine patients died secondary to disease complications. Overall survival was 95% at 15 years of age. The registry provides data about the prevalence of hemoglobinopathies in Spain and will permit future cohort studies and the possibility of comparison with other registries. © 2016 Wiley Periodicals, Inc.

    2005-08-01

    Full Text Available Fractography is a very useful tool to learn about the mechanisms controlling the fracture process. In this work, the fractographical uses of laser scanning confocal microscopy (LSCM are shown. LSCM is a widely used technique in Biology and similar disciplines, but its use in Materials Science is not yet as explored. However, it is an ideal technique for fractographical studies, since by using it the three-dimensional profile of the fracture surface can be obtained. From this profile, it is possible to extract information, like the roughness of the fracture surface, which would be very difficult to obtain from other studies. In this paper, LSCM is applied to the study of the fracture surface in ceramic fibers submitted to tensile stress, making the interest of the technique evident due to features such as easy sample preparation, gathering of real 3D information, and good SEM-LSCM synergy.

    La fractografía en materiales resulta de gran utilidad para la caracterización de los mecanismos que dominan la rotura. En el presente artículo se investigan las aplicaciones fractográficas de la microscopía óptica confocal o LSCM (Laser Scanning Confocal Microscopy. Dicha técnica es de amplio uso en Biología y disciplinas afines, pero su empleo en Ciencia de Materiales está poco explorado. Sin embargo, resulta ideal para el estudio fractográfico, ya que permite obtener reconstrucciones del perfil tridimensional de la superficie de fractura. De este perfil tridimensional puede extraerse información —la rugosidad de la superficie, por ejemplo— muy difícil de obtener a partir de otro tipo de estudios. En este trabajo se aplica LSCM a la caracterización de superficies de fractura en fibras cerámicas sometidas a tracción y se pone de manifiesto el interés de la técnica, debido a características tales como la preparación sencilla de muestras, la obtención de información tridimensional real y la buena coordinación SEM-LSCM.

    Full Text Available En los últimos años, los regímenes actuales de movilidad urbana cotidiana y sus efectos sociales y medioambientales han sido materia de debate y preocupación pública. En el presente artículo pretendemos explorar el tema a través de un caso de estudio específico: el análisis de los motivos y percepciones detrás de la adquisición y el uso de automóviles por parte de habitantes de bajos ingresos de la ciudad de Santiago, Chile. En primer lugar veremos cómo puede ser entendido el automóvil y el tipo de movilidad urbana que genera desde una óptica de teoría social y urbana. En segundo lugar, presentaremos algunas tendencias generales de uso de automóviles en Santiago. Luego se analizarán en detalle los principales argumentos detrás de la adquisición, uso y valoración del automóvil por parte de un grupo de usuarios de bajos ingresos de la ciudad. Finalmente entregaremos, a partir de los análisis presentados, algunas ideas que pueden contribuir al diseño de políticas públicas que incentiven formas de movilidad urbana sustentables en la ciudad.In recent years, existingforms of daily urban mobility and their social and environmental impacts have become issues of debate and public concern. In this article we explore this issue through a specific case study: the analysis of the motives and perceptions that lie behind the acquisition and use of cars by low income residents in Santiago de Chile. Firstly we analyze how the car and the type of urban mobility that is generated are understood in terms of social and urban theory. Secondly, we present some general tendencies of car use in Santiago. Next we look in detail at the principal arguments behind acquisition, use and valuing of the vehicle by a group of low income users in the city. Finally, we offer, based on the analysis, some ideas that can contribute to the design of public policies that incentivize forms of sustainable urban mobility in the city.

Métodos: Estudo transversal realizado através de questionário em pacientes atendidos no serviço de lentes de contato do ambulatório do SUS do Hospital de Olhos do Paraná, no período de 02 de setembro de 2014 a 04 de agosto de 2015. Resultados: Dos 69 entrevistados, 56,52% fizeram LC. Destes, 55,07% têm entre 20-49 anos, 69,56% são mulheres, 40,58% com ensino médio completo e 36,23% com 2 a 6 salários mínimos. Predominaram a lente rígida com 66,67%, com menos de 8 horas de uso em 41,02% e desconforto durante o uso em 59%. A limpeza das LC é feita ao colocar e ao retirar em 87,18% dos casos, com 71,8% utilizando solução própria para LC. Alto custo da compra foi o principal motivo do não uso de LC, com 70% dos pacientes que não fizeram uso desse recurso. Conclusões: Dos entrevistados, 56,52% iniciaram o uso de LC, sendo o ceratocone a doença mais indicada. Foi demonstrado nesse estudo que os pacientes em questão têm boa orientação quanto a manuseio e manutenção das LC. Apesar dos inquestionáveis avanços da tecnologia médica, continuam ocorrendo a desistência do uso desse recurso principalmente pelo custo e medo do manuseio. É responsabilidade do especialista esclarecer os benefícios que os pacientes com indicação médica terão com o uso de LC, assim como motivar o seu uso.

    Full Text Available Para efectuar la caracterización morfológica y óptica en películas de diamante se utilizó la microscopía de barrido electrónico (MBE y espectroscopias de transformada de Fourier infrarroja (TFI y Raman. Para esto se depositaron diversas películas de diamante usando la flama de un soplete de oxígeno-acetileno a una temperatura del substrato de 800°C y en atmósfera abierta. Las micrografías MBE muestran que la morfología y espesor de las películas varían según las condiciones empleadas en su obtención. También hay información detallada acerca de la estructura en la superficie del diamante obtenida por espectroscopia infrarroja. De esta manera, se analiza la naturaleza de las especies químicamente absorbidas durante el proceso de crecimiento como resultado de la reacción química: C2H2 + O2 Æ 2CO + H2, llevada a cabo en los primeros instantes de la deposición. Además, se estudió la calidad de las películas mediante espectroscopia Raman, una de las técnicas más sensibles y poderosas, ya que permite distinguir las diferentes fases del carbón. Con esta técnica se obtuvo una banda en 1332 cm-1 que es característica de la estructura sp3 del diamante, la ausencia de señales alrededor de 1560 cm-1 es característico de las películas de diamante de buena calidad. Se presenta también una breve discusión del papel que juegan las especies químicamente absorbidas en los primeros instantes en que se produce la deposición del diamante y durante su proceso de crecimiento

    Discutimos nossa participação em um curso de treinamento para professores de diversas disciplinas do ensino médio. Nossa preocupação básica foi desenvolver instrumentos educacionais adequados para levar à sala de aula, nesse nível de ensino, de forma contextualizada, questionamentos freqüentes dos alunos sobre astronomia e sua relação com tecnologia e sociedade. Encaminhamos questões como: a evolução da astronomia, suas relações com outros ramos do conhecimento humano e conseqüentes aplicações; avanços na tecnologia dos instrumentos ópticos versus a importância da observação do céu a olho nu; a relação entre olho humano, luneta e telescópio; e desenvolvimento da tecnologia espacial e sua influência em nosso cotidiano. Objetivamos com isto fazer um resgate histórico e pedagógico das aplicações e observações do céu no cenário escolar, destacando a relação entre eventos astronômicos, olho humano, instrumentos mediadores e suas contextualizações históricas e sociais. Produtos desta abordagem foram o desenvolvimento e a adaptação de práticas e materiais instrucionais diversos (e.g., "espelhos" de isopor e "raios luminosos" de bolinhas de gude; montagens envolvendo velas, lasers, lentes e espelhos; desmonte e análise de peças de um telescópio; etc.). Além disto, como outro resultado deste trabalho, elaboramos textos sobre história da astronomia e da óptica para atividades em classe. Com estas ações visamos facilitar a concretização de conceitos físicos envolvidos, exemplificar um ensino contextualizado e interdisciplinar motivado por temas astronômicos e favorecer que práticas e discussões feitas com os treinandos possam ser transpostas para a sala de aula. A reação dos professores às práticas propostas foi bastante positiva. Todos esses aspectos são discutidos em detalhe neste trabalho. (PPGECNM/UFRN; PRONEX/FINEP; NUPA/USP; Temáticos/FAPESP)

  19. Water Markets in Spain: Performance and Challenges

    Full Text Available Law 46/1999 incorporated formal water markets into the Spanish legal and regulatory framework, allowing spot water markets and the creation of water banks. The implementation of water markets in Spain aimed at improving the efficiency of water use by reallocating water towards uses with higher added value. However, the performance of water markets in Spain has been rather disappointing, since they have been operative only during drought periods, and even under these extreme scarcity situations, trading activity counted for less than 5.0% of total water use. The narrowness of the market suggests that there are some barriers hampering their effective functioning. This paper examines the evolution and performance of water markets in Spain, relying on a transaction costs analysis framework. This analysis allows the identification of the main factors impeding water markets from operating effectively as a water reallocation tool. This analysis also provides some guidelines on how to overcome these obstacles and, thus, how to improve the efficiency of water use.

  20. Small hydro: Policy and potential in Spain

    Gutierrez, C.

    2001-01-01

    In Spain, the benefits of small-scale (less than 10 MW) hydro are apparently rarely appreciated and there is little support from European institutions. The article suggests that small hydro technology can make a significant contribution to the country's energy requirements and create employment, provided certain obstacles can be removed. Data on the number of small hydros in Spain, and of recent installations are given; the share of hydro in Spain's total energy production is 2.5%. The low environmental impact of hydro is extolled, and the conclusions of a recent study of 'environmental impacts of the production of electricity' are listed. There are said to be unreasonable administrative obstacles; for example, it is more difficult to obtain permission to refurbish a 100 kW hydro plant in Castilla y Leon than it is to install a 30,000 kW gas plant. Some details relating to the affect of hydro on aquatic ecosystems, noise levels, and water quality, are given

    Full Text Available PURPOSE: Pauses in verbal expression of thought flow in patients with partial epilepsy was studied in order to achieve a best comprehension of brain interhemispheric influences. METHOD: We studied thirty nine patients with partial epileptic seizures and twenty four volunteers (control group. Free association of ideas was used as a method to stablish the thought flow, starting with a stimulus word (subject name that must be followed by spontaneous and consecutive word-phrase. Patients were instructed to say any thought that came to their minds without any kind of censoring. Subject responses were recorded through a PC keyboard and time intervals (pauses between each word-phrase were processed by a software developed for this purpose. RESULTS: Time intervals reduction among associations in right lesional group were compared to left lesional, right non-lesional and control groups. An increase of associative time intervals was observed in the right non-lesional group compared to left non-lesional group. CONCLUSIONS: We suggest a possible inhibitory inter-hemispheric function of the right hemisphere modulating verbal expression of the thought flow. Considering the hypothesis of the inter-hemispheric inhibition by the right hemisphere on left hemisphere, we admit that in epileptic patients with right hemispheric lesion there is an attenuation of the inter-hemispheric inhibition and an increase in thought flow, whereas in patients without a lesion but a paroxysmal epileptic activity in right temporal lobe there is an exacerbation of this inhibitory function and consequent reduction in the thought flow.OBJETIVO: Foram estudadas as pausas na expressão verbal do pensamento em pacientes com epilepsia parcial a fim de estabelecer uma melhor compreensão das influências interhemisféricas cerebrais.

    Mercury is a toxic metal that is released into the environment as a result of various industrial and agricultural processes. It can be accumulated by domestic animals and so contaminate human foodstuffs. To date, there is no information on mercury residues in livestock in Spain and the aim of the present study was to quantify the concentrations of mercury in cattle in two of the major regions in north-west Spain, Galicia (a largely rural region) and Asturias, which is characterised by heavy industry and mining. Total mercury concentrations were determined in tissue (liver, kidney and muscle) and blood from 284 calves (6-10 months old) and 56 cows (2-16 years old) from across the whole of the two regions. Mercury was usually detected in the kidney (62.4-87.5% of samples) but most (79.5-96%) liver, muscle and blood samples did not contain detectable residues. Renal mercury concentrations did not differ between male and female calves but were significantly greater in female calves than in cows. Unexpectedly, kidney mercury concentrations were significantly higher in calves from the predominantly rural region of Galicia (geometric mean: 12.2 microg/kg w.wt.) than in animals from the industrialised-mining region of Asturias (3.40 microg/kg w.wt.). Overall, mercury residues in cattle from NW Spain were similar to those reported in cattle from non-polluted areas in other countries and do not constitute a risk to animal or human health.

    Full Text Available Abstract Background No large scale studies on breastfeeding onset patterns have been carried out in Spain. This work aims to explore the prevalence and the risk factors for not initiating breastfeeding in hospitals from Catalonia (CAT and Valencia (V, two regions accounting approximately for 30% of the annual births in Spain. Methods The prevalence of not initiating breastfeeding was calculated by maternal/neonatal characteristics and type of hospital, and logistic regression models were used to estimate crude and adjusted risks of not breastfeeding in each region. Results Prevalence of breastfeeding initiation was 81.7% and 82.5% in Catalonia and Valencia, respectively. We identified conspicuous regional differences in the adjusted-risk of not breastfeeding, especially for multiple [CAT = 3.12 (95% CI: 2.93, 3.31, V = 2.44 (95% CI: 2.23, 2.67] and preterm and low birth weight deliveries [very preterm and very low birth weight: CAT = 7.61 (95% CI: 6.50, 8.92, V = 4.03 (95% CI: 3.13, 5.19; moderate preterm and moderate low birth weight: CAT = 4.28 (95% CI: 4.01, 4.57, V = 2.55 (95% CI:2.34, 2.79]. Conclusions Our results suggest the existence of regional variations in breastfeeding initiation in Spain. Taking into account the known short and long-term benefits of breastfeeding it is recommended that further research should explore these differences in order to prevent potential inequities in neonatal, child and adult health.

    The data of the ISAAC project in Spain show a prevalence of childhood asthma ranging from 7.1% to 15.3%, with regional differences; a higher prevalence, 22.6% to 35.8%, is described for rhinitis, and atopic dermatitis is found in 4.1% to 7.6% of children. The prevalence of food allergy is 3%. All children in Spain have the right to be visited in the National Health System. The medical care at the primary level is provided by pediatricians, who have obtained their titles through a 4-yr medical residency training program. The education on pediatric allergy during that period is not compulsory and thus very variable. There are currently 112 certified European pediatric allergists in Spain, who have obtained the accreditation of the European Union of Medical Specialist for proven skills and experience in pediatric allergy. Future specialists in pediatric allergy should obtain their titles through a specific education program to be developed in one of the four accredited training units on pediatric allergy, after obtaining the title on pediatrics. The Spanish Society of Pediatric Allergy and Clinical Immunology (SEICAP) gathers over 350 pediatric allergists and pediatricians working in this field. SEICAP has a growing activity including yearly congresses, continued education courses, elaboration of technical clinical documents and protocols, education of patients, and collaboration with other scientific societies and associations of patients. The official journal of SEICAP is Allergologia et Immunophatologia, published every 2 months since 1972.

    Even when the basic requirements for a Quality Assurance Program are delineated in documents such as the Code of Federal Regulations or Standards like ANSI N 45. 2, the way in which these requirements are put into practice is very dependent on the organization to which they are applied. So, in order to approach accurately the Quality Assurance practice and experience in Spain, the legal and industrial scenario must be considered. We are trying to present an outlook of the Spanish Energy Plan, Regulations and Nuclear Industry. (orig.)

    According to the Directive 2009/28/EC of the European Parliament and of the Council on the promotion of the use of energy from renewable sources the target for the share of energy from renewable sources in gross final consumption of energy in the year 2020 for Spain is 20% (according to EurObserv'ER calculation the share was 14.2% in 2012). The Directive has a mandatory 10 % target for transport to be achieved by all Member States, which refers to renewable sources as a whole, not bio-fuels alone. In Spain, the main support scheme called 'Regimen Especial' (Royal Decree 661/2007) operated until the end of 2011 was suspended at the beginning of 2012. The price regulation system is currently phased out trough Real Decreto 9/2013. In the former system, operators could choose between two options: a guaranteed feed-in tariff and a guaranteed bonus (premium) paid on top of the electricity price derived on the free market. More recently, the 6 June, Spain approved a clean energy bill that introduces an entirely new subsidy system. The FiT and market price plus premium systems have effectively been abolished retroactively and replaced by a sum to be allocated based on the plant's installed capacity to compensate for investment-related financial outlay. Under the decree, generators will earn a rate of return of about 7.5 percent over their lifetimes. This rate, which may be revised every three years, is based on the average interest of a 10-year sovereign bond plus 3 percentage points. These measures will be implemented retroactively to apply from July 2013. Currently, there is no support scheme for RES-H and C in place in Spain but building must satisfy a minimal solar contribution of warm sanitary water. Approved in March 2006, through Royal Decree 314/2006 of 17 March 2006, the Building Technical Code (CTE - Codigo Tecnico de la Edificacion) requires all new or renovated buildings to cover 30%-70% of the Domestic Hot Water demand with solar thermal energy.

    In recent decades there have been significant legislative changes in Spain. Society develops faster than laws, however, and new challenges have emerged. In 2004, the Spanish Association of Relatives of the Mentally Ill (FEAFES) proposed amending the existing legislation to allow for the implementation of involuntary outpatient treatment (IOT) for patients with severe mental illness. Currently, and after having made several attempts at change, there is no specific legislation governing the application of this measure. Although IOT may be implemented in local programmes, we consider legal regulation to be needed in this matter. Copyright © 2015 Elsevier Ltd. All rights reserved.

A survey to summarize the evolution of HTA was sent to representatives of different HTA initiatives in Spain. HTA was introduced in the late 1980s. The main factors were the trend to an increase in healthcare expenditure, concerns regarding efficiency in providing health care, as well as in the level of rationality introducing high technology. Spain has direct (i.e., regulation) and indirect (i.e., payment systems, evidence-based programs, HTA) mechanisms to control health technologies. A recent high priority regulation has established the need of HTA to decide the introduction of a new health technology in the lists of public healthcare coverage, although similar regulations existed in the past and were scarcely implemented. HTA initiatives started at the regional government level. Its introduction followed a progressive pattern among regions. In the beginning, resources were scarce and expertise limited, with work done at intramural level. With time, expertise increase, and promotion of commissioned work was implemented. HTA knowledge transfer in the healthcare system has been carried out through courses, publications, and commissioned research. Currently, there are seven HTA units/agencies, which coordinate their work. HTA in Spain is in its maturity. Facing the unavoidable change of health care environment over time, HTA is also evolving and, currently, there is a trend to broaden the areas of influence of HTA by devolving capacity to hospitals and applying principles to very early phases of health technology development, under the umbrella of regional HTA units/agencies. However, there are two main challenges ahead. One is to have a real impact at the highest level of healthcare policy coordination among Spanish regions, which is done at the Central Ministry of Health. The other is to avoid the influence of political waves

    2012-12-01

    This article focuses on household water use in Spain by analyzing the influence of a detailed set of factors. We find that, although the presence of both water-saving equipment and water-conservation habits leads to water savings, the factors that influence each are not the same. In particular, our results show that those individuals most committed to the adoption of water-saving equipment and, at the same time, less committed to water-conservation habits tend to have higher incomes.

    Full Text Available En la actualidad, las redes móviles e inalámbricas de nueva generación, tales como las redes de área personal IPv6 de baja potencia (6LoWPAN, redes de sensores inalámbricos sobre IPv6 y redes móviles IPv6 jerárquicas se encuentran bajo rigurosa investigación y desarrollo, pues representan el paso por seguir en la evolución de las redes Machine-to-Machine (M2M, al tiempo que apoyan el acceso de banda ancha de la próxima generación de tecnologías y sistemas inteligentes sobre Internet futuro. Estas redes de nueva generación imponen restricciones en cuanto al poder de procesamiento, ancho de banda y recursos de energía, lo que re¬presenta una gran limitante en la implementación de mecanismos de seguridad. En este sentido, en lo últimos años han surgido diversas propuestas para la administración de claves, procedimientos de firma digital y cifrado de datos basados en curvas elípticas e híper-elípticas, que logran niveles de seguridad equivalentes a los algoritmos convencionales basados en algoritmos Diffie-Hellman y Rivest-Shamir-Adleman (RSA, pero que reducen la longitud de clave y, por ende, los recursos computacionales y de red asociados. Este artículo examina los algoritmos basados en criptografía de curvas elípticas (ECC y su aplicación a redes móviles e inalámbricas de nueva generación habilitadas para IPv6. Así mismo, describe un modelo de simulación para la evaluación de ECC, donde se comparan los recursos computacionales necesarios y las limitaciones en mecanismos ligeros de seguridad.

The optical constants of the photodoped thin-film samples have been calculated from the envelopes of the transmission spectra, taken at normal incidence. The dispersion of the refractive index was analysed on the basis of the single-oscillator model proposed by Wemple and DiDomenico. This model allows obtaining structural information of the silver-photodoped layers from optical data. The optical absorption edge is described using the non-direct transition model suggested by Tauc, and a clear decrease of the optical gap of the photodoped product, with the silver content, has been found.Se han preparado láminas delgadas amorfas calcogenuras de composición Agx(As0.33S0.67100-x, mediante el fenómeno fotoinducido conocido como fotodisolución o fotodopaje, alcanzándose concentraciones de Ag en las muestras de hasta un 16.5 % at.

    Congestive heart failure has a high mortality, as reflected in different clinical trials and observational studies. Spain, as other countries around the Mediterranean basin, have a relatively low rate of coronary deaths, attributed to the so-called Mediterranean lifestyle. Andalusia, in the southern most part of Spain, constitutes the paradigm of Mediterranean lifestyle. However, different reports show that the prevalence of ischemic heart disease is higher in Andalusia than in other zones of Spain. Thus the mortality rate due to heart failure in Spain in the year 2000 per 100,000 inhabitants was 27.3 in men and 28.88 in women and each one of the eight Andalusia provinces had greater rates than the national mean in both men and woman. Even in countries with a relatively low prevalence of coronary heart disease as is the case in Spain, heart failure mortality seems to be parallel to local differences in IHD prevalence.

    1993-01-01

    ENRESA (Empresa Nacional de Residuos Radiactivos, S.A.), is a State-owned company, founded in 1985 and is responsible for radioactive waste management in Spain. ENRESA's activities are developed following a General Radioactive Waste Plan approved by the Spanish Government. As in most countries, Spanish public opinion is concerned with the most activities related to radioactivity or rad-waste management due to different facts but mainly to a lack of information on the matter. This situation provides misuse of information on it by some politicians, green groups and media which increases distrust of public on responsible companies and institutions. To gain public acceptance, it would be necessary to develop long-term information policy, due to the fact that results in communication are reached in the long term. ENRESA is carrying out a Communication Plan (CP) which has been implemented in a continuous way with success around the area of the disposal site of low and intermediate level wastes as well as around an old uranium mill factory in which remedial actions are being implemented. The implantation of CP at a national level is being done stepwise. The more relevant issues related to the radioactive waste situation in Spain, as well as the communication actions are explained in this document

    The introduction of nuclear power in Spain is developing very rapidly. At present 1.1GW(e) are installed in Spain and this is expected to increase to 8GW(e) in 1980 and to 28GW(e) in 1990. Spanish industry and technology are also rapidly increasing their participation in building nuclear stations, in manufacturing the necessary components and in the activities related to the nuclear fuel cycle. All of this requires properly trained personnel, which is estimated to become approximately 1200 high-level technicians, 1100 medium-level technicians and 1500 technical assistants by 1980. This personnel is trained: (a) in engineering schools; (b) in the Nuclear Studies Institute; (c) in the electric companies with nuclear programmes. The majority of the high-level engineering schools in the country include physics and basic nuclear technology courses in their programmes. Some of them have an experimental low-power nuclear reactor. The Nuclear Studies Institute is an official organism dependent on the Nuclear Energy Commission and responsible, among other subjects, for training personnel for the peaceful use and development of nuclear energy in the country. The electric companies also participate in training personnel for future nuclear stations and they plan to have advanced simulators of PWR and BWR type stations for operator training. The report deals with the personnel requirement forecasts and describes the training programmes. (author)

    The growing involvement in Spain by civil society in the demand for tobacco control policies has been notable. The basis for the creation of the National Committee for Tobacco Prevention was established in 2004. At the end of that year, an intensive intervention was aimed at specifying, in law, the regulatory actions in the National Plan for Tobacco Prevention. This would facilitate a qualitative leap, taking advantage of the legal transposition of the European directive on advertising. With broad political consensus, the Law 28/2005 was established regarding sanitary measures for tobacco and the regulation of the sale, supply and consumption of tobacco products. The objective stated in this law is to prevent the initiation of tobacco consumption, especially among youth, guarantee the right of non-smokers to breathe air free from tobacco smoke and make quitting this habit easier for people who wish to do so. The main issues included are the prohibition of tobacco advertising and the limitation of tobacco consumption in common work areas and enclosed public spaces. The new law has replaced the previous rules in Spain, which were some of the most permissive in the European Union in terms of tobacco sales, advertising limitations and restrictions on smoking locations. It is clear that there is still much to be done. At this time, more social support needs to be generated in favor of the new regulations, and an important effort needs to be made to educate the public.

    2015-05-01

    Full Text Available As part of legal psychology, as it is understood in Spain, we can distinguish between the applications of psychology in the different steps of the judicial process: in police stations during criminal investigations, in court when the perpetrators have already been identified and arrested, and in prisons where they are eventually sent after being convicted. This paper argues that when psychology assists the criminal investigation in the first step of the judicial process - the police activities-, we are talking about criminal psychology, at two levels: the operational level (mostly pertaining to criminal psychology and the strategic level (shared with other areas of expertise. After describing its peculiarities and specific areas, in analogy with the support provided by other forensic sciences, we explain that in Spain this specialty is carried out professionally from within our own police forces, with a profile that is very different from the more traditional police psychology, and in close collaboration with the academic environment with regard to the scientific development of techniques and procedures.

  18. [Abortion. Spain: the keys to the controversy].

    Science.gov (United States)

    1983-01-01

    For many years, illegal abortion has been denounced in Spain. The estimate of 300,000 abortions annually is widely quoted but poorly founded in fact. Weekend "charters" to London and Amsterdam for women seeking abortions have been commented upon, denounced, and caricatured. The evidence indicates that abortions occur in Spain despite their illegality, just as they occur in every other country and have always occurred. Poor women abort in a poor way, with traditional healers, while rich women abort in a rich way, with physicians. "Charters" are the solution of the middle class. Proposed legislation in Spain would permit abortion on 3 grounds: rape, fetal malformation, and risk to the woman's life if the pregnancy continued. Excesses have been committed both by those opposing abortion and by those struggling for liberalization of laws. Defenders of abortion, such as radical feminists, appear to forget that abortion is a medical procedure with possible dangerous psychophysical consequences, and that preventive measures such as sex education and diffusion of contraception or social measures such as assistance for unwed mothers and their children would be preferrable to abortion. There is the question of whether medical personnel should be excused from assisting in abortions on grounds of conscience and whether those who do assist in abortions automatically become "progressive" by doing so. The staunchest defenders of fetal life are not moved to contribute anything beyond words to improvement of the plight of the many millions of already born who live in miserable conditions of hunger and want. Abortion is a violent act against the fetus and the pregnant woman. Its criminalization is a violent act against the woman and a social intrusion into matters better left to personal ethics. The government which proposes abortion on a few grounds fails to initiate a program to promote life through social protection of single mothers and their children or of families in general

    1985-01-01

    The access of Spain and Portugal to the European Community of Atomic Energy (EURATOM) will give rise to significative consequences and it is a subject which must be thoroughly considered as to its implications regarding the present state of nuclear development in both countries and with regard to their reciprocal relations in nuclear energy matters. To determine such consequences and implications it is necessary, first of all, to analyze what EURATOM is and how it acts, in addition to consider the situation of each of its Member States as to the utilization of nuclear energy. As well, it is necessary to explain the evolution and the present situation of nuclear development in Spain and in Portugal and their mutual relations in this field. In pursuit of such analysis we may determine the possible consequences of their access; this is made bearing in mind each of the aspects in which EURATOM acts, according to the Treaty and the ''acquis communitaire'', and dividing them into common consequences and individual ones for both countries. The whole exposition, which was studied and carried out from an exclusively technical point of view, has a result the deduction of the joint possibilities offered to Spain and Portugal to make use of EURATOM's availabilities and of the joint actions which both countries may achieve to benefit as much as possible from their access to EURATOM.

    2016-06-01

    Full Text Available Among the devotions to the black Saints, the one of which Benedict of Palermo was the object in Spain in the 17th and 18th centuries was the most remarkable. Born near Palermo to African slaves, this lay brother of a Sicilian franciscan convent, died in the odor of sanctity in 1589. His immediate popularity, encouraged both by the Church and by the Hispanic monarchy, was considerable within the communities of slaves and free blacks. Benedict was beatified in 1743, event which was followed by numerous celebrations and his eventual canonization in 1807. The fervour which surrounded him fade gradually because of the competition represented by the devotion to other black saints and by the very visible decline of slavery. However, thanks to the efforts of the franciscan order, the worship of Saint Benoît of Palermo continued until our days, particularly in Galicia.

    On 25 April 1998, the mineral waste retaining wall at the Swedish-owned pyrite mine at Aznalcóllar (Seville, Spain) burst, causing the most harmful environmental and socio-economic disaster in the history of the River Guadiamar basin. The damage was so great that the regional government decided in May 1998 to finance a comprehensive, multidisciplinary research initiative with the objective of eradicating or at least minimising all of the negative social, economic and environmental impacts. This paper utilises a Strengths, Weaknesses, Opportunities and Threats (SWOT) analysis to identify eight strategic measures aimed at providing policymakers with key guidelines on implementing a sustainable development model, in a broad sense. Empirical evidence, though, reveals that, to date, major efforts to tackle the negative impacts have centred on environmental concerns and that the socio-economic consequences have not been completely mitigated.

The main clinical findings are fever and exanthema, although there may be severe forms, particularly in secondary infections. Five children with a primary, non severe dengue infection are presented. The diagnosis was based on clinical suspicion and epidemiological history, and confirmed by immunochromatography and ELISA tests. The outcome was favourable in all cases. It is important to consider this diagnosis in international travellers that present with fever within the 14 days of returning from an endemic area, in order to get an early diagnosis, adequate treatment and a good prognosis.

    Segarra, F

    1979-04-01

    About 50 cases of asbestosis have been descirbed in Spain from 1948 through 1974. Since 1975 the Instituto Territorial de Barcelona, Servicio Social de Higiene y Seguridad del Trabajo, has initiated a survey of all the industries with an asbestosis risk in the Barcelona area. Nearly 300 cases of asbestosis have been detected to date. Given the poor hygienic conditions of most of the industries, with an asbestosis risk, and the considerably large number of exposed people, it can easily be predicted that a rapid increase of the incidence of the disease in the years to come will occur. Most of the observed cases in Barcelona were from two fibrocement industries. Of a total of 1003 workers examined, 247 (about 25%) had asbestosis.

    1983-01-01

    In order to meet current Spanish engineering criteria as well as to provide for likely future Spanish Regulatory requirements, utilities committed to a major policy change in the preferred radwaste solidification media. In the early 1970's Spanish utilities, following the United States experience, purchased inexpensive solidification systems which used urea formaldehyde (UF) as the binding matrix. By the late 1970's the Spanish utilities, seeing the deterioration of the UF position and slow progress toward its improvement, unilaterally changed their binding matrix to cement. This paper illustrates the implementation of this change at the ASCO Nuclear Plant. The problems of layout modifications, shortened delivery schedule and criteria unique for Spain are addressed. Also presented is the operating experience acquired during the pre-operational start-up of the ASCO I Radwaste System

    Indoor radon measurements are usually associated with housing. However, a typical person spends about one-third of the day at their workplace. A survey was made of radon levels in workplaces in Extremadura (Spain). More than 200 measurements were performed in some 130 firms and organizations of different sectors (urban wellness centres, spas, caves, mines, water management facilities, underground carparks, wine cellars, museums, etc.). Activated charcoal canisters and track detectors were used for sampling. The results indicated the importance of performing this type of measurement because the exposure of workers can reach high values in some cases. - Highlights: ► More than 200 measurements were performed in about 130 working places. ► Activated charcoal canisters and track detectors were used for sampling. ► The exposure of workers can reach high values in some cases. ► Geological characteristics of the soil influence the indoor radon levels.

    2013-01-01

    In Spain, cerebrovascular disease (CVD) is a very common cause of morbidity and hospitalization. They are the second leading cause of mortality in the general population, and the first in women. They also constitute a very high social spending, which is estimated to increase in coming years, due to the aging of our population. Data from the Hospital Morbidity Survey of the National Statistics Institute recorded, in 2011, 116,017 strokes and 14,933 transient ischemic attacks, corresponding, respectively, to an incidence of 252 and 32 events per 100,000 people. In 2002, the cost of hospitalization for each stroke was estimated at €3,047. The amount of total cost health care throughout the life of a stroke patient is calculated at €43,129. Internationally, the direct costs of stroke constitute 3% of national health spending, this being similar amount in different countries around us. Hypertension was the cardiovascular risk factor (CVRF) more prevalent in both ischemic and hemorrhagic strokes, followed by dyslipidemia and diabetes mellitus. Peripheral arterial disease and hypertension were more frequently associated with atherothrombotic events, atrial fibrillation with cardioembolic strokes, and obesity and high blood pressure to lacunar infarcts. In Spain, as showing several studies, we are far from optimal control of CVRF, especially in secondary prevention of stroke. According to the ICTUSCARE study, achieving recommended values was 17.6% in the case of hypertension, 29.8% in LDL-cholesterol, 74.9% of smoking, and 50.2% in diabetes mellitus. In this review, we analyze in detail the epidemiology, prevention and costs originated by CVD. Copyright © 2013 Elsevier España, S.L. y SEA. All rights reserved.

    To analyze gender inequalities in employment and working conditions, the work-life balance, and work-related health problems in a sample of the employed population in Spain in 2007, taking into account social class and the economic sector. Gender inequalities were analyzed by applying 25 indicators to the 11,054 workers interviewed for the VI edition of the National Working Conditions Survey. Multivariate logistic regression models were used to calculate odds ratios (OR) and 95% confidence intervals (95% CI), stratifying by occupational social class and economic sector. More women than men worked without a contract (OR=1.83; 95% CI: 1.51-2.21) and under high-effort/low-reward conditions (1.14:1.05-1.25). Women also experienced more sexual harassment (2.85:1.75-4.62), discrimination (1.60:1.26-2.03) and musculoskeletal pain (1.38:1.19-1.59). More men than women carried out shift work (0.86:0.79-0.94), with high noise levels (0.34:0.30-0.40), and high physical demands (0.58:0.54-0.63). Men also suffered more injuries due to occupational accidents (0.67:0.59-0.76). Women white-collar-workers were more likely than their male counterparts to have a temporary contract (1.34:1.09-1.63), be exposed to psychosocial hazards and discrimination (2.47:1.49-4.09) and have occupational diseases (1.91:1.28-2.83). Gender inequalities were higher in the industry sector. There are substantial gender inequalities in employment, working conditions, and work-related health problems in Spain. These gender inequalities are influenced by social class and the economic sector, and should be considered in the design of public policies in occupational health. Copyright © 2011 SESPAS.

    This study aims to analyze the differences in the use of primary care (PC), hospital, and emergency services between people born in Spain and immigrants. Data were obtained from the 2006 Spanish National Health Survey. The sample was composed of individuals aged 16-64 years from Spain and the seven countries with most immigrants in Spain (n = 22,224). Hierarchical multiple logistic regression models were fitted. Romanian men were less likely to use health care at all levels compared to men from other countries. Women from Argentina, Bolivia and Ecuador reported a lower use of PC. Among women, there were no differences in emergency visits or hospitalizations between countries. Bolivian men reported more hospitalizations than Spanish men, whereas Argentinean men reported more emergency visits than their Spanish counterparts. In Spain, most immigrants made less than, or about the same use of health care services as the native Spanish population.

    2011-03-01

    Full Text Available We present a detailed characterization of two calcareous stones from Andalusia (Southern Spain, namely Escúzar calcarenite and Olivillo travertine. Both materials can replace two stones extensively used in the architectural heritage of Andalusia, i.e. La Escribana calcarenite and Alfacar travertine. To establish the suitability of the replacement of ancient materials, detailed examination was performed. X-ray diffraction, X-ray fluorescence, optical and scanning electron microscopy, hydric tests, mercury intrusion porosimetry, gas adsorption, ultrasounds and colorimetry were applied. The Escúzar calcarenite has large pore cavities and higher open porosity than La Escribana calcarenite. From a chromatic point of view both calcarenites are rather similar. The Olivillo travertine is a massive well cemented and heterogeneously colored rock. The ultrasounds velocities for this material are very homogeneous and elevated, indicating excellent mechanical properties. However the hydric and chromatic differences between both travertines point to reduced adequacy of Olivillo travertine as substitutive material for Alfacar.

    Se han caracterizado dos rocas carbonáticas de Andalucía Oriental; la calcarenita de Escúzar de Granada y el travertino Olivillo de Alhama de Almería. Ambas podrían reemplazar a dos materiales del patrimonio arquitectónico de Andalucía, la calcarenita La Escribana y el travertino Alfacar ambos de Granada. Los materiales mencionados se estudiaron mediante difracción y fluorescencia de rayos X, microscopías óptica y electrónica de barrido, ensayos hídricos, porosimetría de mercurio, adsorción de gases, pulsos ultrasónicos y parámetros cromáticos. La calcarenita Escúzar presenta grandes poros y una porosidad abierta y área superficial superior a la calcarenita La Escribana; el cromatismo de ambas es similar. El travertino Olivillo es una roca masiva poco porosa

FONTES DOS DADOS : Livros técnicos e bases de dados MEDLINE e LILACS de 1966 a 2006. SÍNTESE DOS DADOS : A úlcera péptica na criança e adolescente pode ser primária, associada à infecção pelo H. pylori, ou secundária, na qual os mecanismos etiopatogênicos dependem da doença de base. A infecção é adquirida predominantemente na infância, com taxas de prevalência que variam de 56,8 a 83,1% nas crianças que vivem nas regiões mais pobres do Brasil e de aproximadamente 10% nas crianças abaixo de 10 anos de idade nos países desenvolvidos. A infecção pode ser diagnosticada por métodos invasivos, que investigam a presença da bactéria, ou de DNA, RNA ou produtos bacterianos em fragmentos de biópsia da mucosa gástrica obtida à endoscopia; também pode ser diagnosticada através de métodos não-invasivos, que compreendem a pesquisa de anticorpos anti-H. pylori em amostras de soro, urina ou saliva, a pesquisa de antígenos da bactéria nas fezes e o teste respiratório com uréia marcada com carbono-13. O método de escolha para o diagnóstico da úlcera péptica é a endoscopia digestiva alta, com a vantagem adicional de, durante o procedimento, permitir a obtenção de fragmentos de mucosa gástrica para o diagnóstico da infecção e estudo histopatológico. CONCLUSÕES: A infecção por H. pylori é a principal causa de úlcera péptica na infância. A erradicação da bactéria com antimicrobiano é acompanhada de cura da doença, sendo, portanto, indicada em todas as crianças H. pylori-positivas com úlcera péptica em atividade, recorrente, cicatrizada ou complicada.OBJECTIVE: To show important aspects of gastroduodenal peptic ulcer and of Helicobacter pylori infection in children and adolescents.

    In this article the Author considers the modern-day and historical situation as regards the administration of justice in Spain, pausing to make a particularly careful analysis of those crimes whose rate of increase, over the past few years, has been the greatest. He runs back over the various stages of Spain's recent history: from the period preceding Franco's regime, during which a multiplicity of criminological theories were developed by Spanish authors, leading to the creation of a school of jurisprudence, in which theory and practice tended toward seeking a balance between freedom and security; through the period of the dictatorship, in which there was a tightening-up of the preceding trend, with a definite predisposition towards security, whether within the State or external to it (to be noted--the Author observes--is that this security in reality is not a guarantee of the lives and liberties of the citizens, but rather only a safeguarding of the State from attacks on its supremacy and power); to the successive period of the democracy, which came about without cruel and revolutionary upsets, but nonetheless has felt for many years the effects of the preceding political climate; criminality is increasing considerably, but the administration of justice is not able to soundly and accurately evaluate it, it having functioned at only 45% efficiency--or so says the Author--up until 1978: the imbalances in the society that can be seen in its passage through the various political regimes are, therefore, present too in the field of criminality; this, in fact, is apparently decreasing (since crimes against the external and internal security of the State are decreasing, as the number of convictions are decreasing); but in reality this criminality is undergoing a strong evolutionary movement, due more than anything else to the fact that the tendency is to give priority to liberty, and no longer to security, as is true in fact of every democratic regime.

METHODS: We report a case of a 33 years old female with limb paraesthesias, weakness in the legs, bowel and bladder dysfunction that was referred to the "Hospital das Clínicas da Faculdade de Medicina de Ribeirão Preto da Universidade de São Paulo" in October 1995. Six years and four months later she had an acute visual involvement. Ophthalmologic examination, laboratory studies, magnetic resonance imaging (MRI and a 24-2 threshold visual field in the Humphrey field analyzer were performed. RESULTS: The MRI scan showed enlargement and cavitation on the spinal cord and chiasmal involvement (thickening of the chiasm with contrast enhancement and no demyelinating lesions in the brain, brainstem, or cerebellum. The central 24-degree threshold field examination showed an inferior visual field defect bitemporally, disclosing a chiasmal involvement. CONCLUSION: Chiasmal involvement may occur in neuromyelitis optica, probably due to a plaque within the chiasm. The authors call attention to the importance of visual field examination with particular regard to quantifying the visual impairment and follow-up of these patients.OBJETIVO: Relatar o caso de uma mulher de 33 anos de idade, com o diagnóstico de neuromielite óptica (síndrome de Devic acometendo o quiasma óptico que apresentou um escotoma incomum no exame de campo visual.

    Public policies are crucial for smoking prevention and improving health among the population. Despite the positive impact in Spain of the law for smoking prevention in 2006, there is room for further improvement in this area of public policy. The estimate of the mortality cost per pack of cigarretes is a crucial factor in cost-benefit analysis for policies aimed to reducing smoking induced mortality. The aim of this paper is twofold. First, we estimate the Value of Statistical Life (VSL) among Spanish smokers. Secondly, we quantify the mortality cost of smoking. We use a hedonic wage model to quantify the marginal value of an increase in the mortality risk in monetary terms. We estimate the model for the Spanish labour market using the European Community Household Data and the Encuesta de Accidentes de Trabajo from the Ministerio de Trabajo e Inmigración. We estimate a VSL of 3.78 million Euros for Spanish smokers. Using this value, in conjunction with the increase in the mortality risk over the life cycle due to smoking, the private mortality cost of smoking is 78 Euros per pack for men, and 54 Euros per pack for women (in 2000 Euros). The mortality cost per pack of cigarettes is highly above its market price.

    The aim of the present work is to determine the association between unemployment and suicide, and to investigate whether this association is affected by changes in the economic cycle or other variables such as age and sex. A time-trend analysis was conducted to study changes in the number of suicides between 1999 and 2013 in Spain. Pearson's correlation coefficients and regression models were used to find the association between unemployment and suicide. A significant positive association was found between unemployment and suicide in the pre-crisis period in men. In that period (1999-2007), each 1% annual increase in unemployment was associated with a 6.90% increase in the annual variation of suicide in the total population, and with a 9.04% increase in the annual variation of suicide in working age men. The correlation between unemployment and suicide is significant in periods of economic stability, but has weakened during the recent financial crisis. Unemployment and suicide have a complex relationship modulated by age, sex and economic cycle. Copyright © 2017 SEP y SEPB. Publicado por Elsevier España, S.L.U. All rights reserved.

    Full Text Available This is a full study of the legal system applicable to selfemployed foreigners wishing to carry out an economic activity in Spain. The focus varies according to the country of origin of the individual, whether it lies within the European Economic Community, whether it is a country with which the European Union has co-operation and association agreements or finally, whether it is under the general regime. The utilitarian perspective which considers immigration as necessary manual labour has justified more efficient legal mechanisms to facilitate the employment of immigrant manual workers. These mechanisms do not apply to self-employed workers. The lack of interest of legislators in this type of worker is highlighted by the suppression of motivation and refusal of the mandatory visa. The detailed analysis of the anticipated administrative requirements emphasises that within the labour legislation for immigrants there is a marked difference between those who work for an employer and those who are self-employed and there is no correspondence or comparison with the more far reaching policies of the labour doctrine with regard to the rights and guarantees of both categories of workers.

    The association between occupational exposure and stomach cancer was investigated in a multicenter case-referent study conducted in Spain on 354 histologically confirmed cases and 354 hospital referents, matched by age, gender, and residence. An increased risk of gastric cancer was found for coal mining workers [odds ratio (OR) 11.8], but the number of workers was small, and therefore the 95% confidence interval (95% CI) was wide (95% CI 1.36-103). An increased risk was observed for wood and furniture workers (OR 1.76), construction workers (OR 1.68), and glass and ceramic workers (OR 2.18), but none of these risks were statistically significant. According to an occupation-exposure linkage system an increased risk was found for occupations associated with exposure to silica and mineral dust (OR 1.80, 95% CI 0.90-3.59). All of the OR estimates were adjusted for the confounding factors socioprofessional status and dietary habits. The possibility of a causal association between stomach cancer and coal and mineral dust is supported by the results.

    The introduction of laparoscopic surgery (LS) can be considered the most important advancement in our specialty in the past 25 years. Despite its advantages, implementation and consolidation has not been homogenous, especially for advanced techniques. The aim of this study was to analyse the level of development and use of laparoscopic surgery in Spain at the present time and its evolution in recent years. During the second half of 2012 a survey was developed to evaluate different aspects of the implementation and development of LS in our country. The survey was performed using an electronic questionnaire. The global response rate was 16% and 103 heads of Department answered the survey. A total of 92% worked in the public system. A total of 99% perform basic laparoscopic surgery and 85,2% advanced LS. Most of the responders (79%) consider that the instruments they have available for LS are adequate and 71% consider that LS is in the right stage of development in their environment. Basic laparoscopic surgery has developed in our country to be considered the standard performed by most surgeons, and forms part of the basic surgical training of residents. With regards to advanced LS, although it is frequently used, there are still remaining areas of deficit, and therefore, opportunities for improvement. Copyright © 2013 AEC.

  12. Low and intermediate waste management in Spain

    International Nuclear Information System (INIS)

    Zuloaga, Pablo

    2002-01-01

    The main objective of this facility is the final disposal of all L and ILW produced in Spain, mainly in the operating Nuclear Power Reactors, in the Nuclear Power Plant under decommissioning by ENRESA, a fuel fabrication plant and institutional producers, as well as those arising from incidents outside the nuclear industry. The disposal concept consists of so called disposal units, mainly durable concrete overpacks, placed in concrete vaults. A drain control system exists in inspection galleries constructed beneath the disposal vaults. These vaults are protected from the weather during their operation and sealing by a metallic shelter, which also supports the handling crane. The facility also include: A treatment and conditioning shop, which includes incineration, institutional wastes segregation and conditioning, drum transfer into overpacks, supercompaction, liquid waste collection, and grout preparation and injection. A waste form characterisation laboratory with means for non-destructive radiological characterisation and for destructive test on the waste forms(specimens extractions, unskinning of the drums, mechanical strength, leaching test on specimens and full size packages) to supports the waste acceptance procedures and the verification of the overall quality of the packages. A fabrication shop for overpacks construction. Auxiliary systems and buildings in support of operation, maintenance and surveillance of the facility. The paper deals with the design, the operating experience of the facility, the waste packages characterisation and acceptance practises and the reception of the wastes from the generating facilities.

    2004-01-01

    The management of radioactive wastes in Spain is undertaken by 'Empresa Nacional de Residuos Radioactivos, S.A.' (ENRESA), the Spanish national radioactive waste company, constituted in 1984. ENRESA operates as a management company, whose role is to develop radioactive waste management programs in accordance with the policy and strategy approved by the Spanish government. Its responsibilities include the decommissioning and dismantling of nuclear installations. ENRESA is a state company whose shareholders are CIEMAT (Centre for Energy-Related, Environmental and Technological Research), previously known as the 'Junta de Energia Nuclear' (Nuclear Energy Council) and SEPI (State Industrial Holding Company). Both of them are governmental institutions with an eighty and twenty percent of the company respectively. In 1980 the Spanish Nuclear Safety Council (CSN) was constituted as the sole competent organisation in the field of nuclear safety and radiological protection, and in general is responsible for regulating and supervising nuclear installations. This organisation, governed by a legal statute, is independent from the administration and reports directly to parliament. (author)

  14. Environmental impact of household activity in Spain

    The objective of this paper is to analyse the environmental impacts of the Spanish economy by way of water and atmospheric pollution on the basis of a Spanish Accounting Matrix for 1999. Only households were taken as an exogenous account. The pollution measures are estimated for seven categories of pollution: three atmospheric pollutants (CO{sub 2}, NO{sub x} and SO{sub x}) and four indicators for water (waste water, nitrogen, metals and biological oxygen demand (BOD)). The environmental data base was obtained from the Spanish Statistical Institute. The analysis reveals that pollution in Spain is closely linked to food production, energy, extractive industries and paper manufacturing. We show that services, taken as a whole, are major polluters, though this is due to the volume of household expenditure they represent rather than their pollution potential as such. We also show that the Spanish economy avoids a great deal of pollution by importing inputs, which pollute where they are produced. Finally, the study also provides per capita pollution values for the aforementioned seven pollutants. (author)

    2008-12-01

    There is increasing concern that studies of public understanding of science, especially biomedicine, should be expected to bring shared frameworks to European and national policies. The present article aims to provide a critical overview of the most recent studies of public understanding of biomedicine in Spain. Specifically, this essay reviews the similarities and differences in the latest European and Spanish surveys. Throughout this article we compare the Third National Survey of Social Perception of Science and Technology produced by the Spanish National Science and Technology Foundation, focusing on issues related to biomedicine, and the Medical and Health Research. A special Eurobarometer Public Survey published by the European Commission. The two surveys were compared attending to the three main common items of science, technology and biomedicine: the level of interest, the level of information and political attitudes. Some discrepancies in the results of the two studies, such as public interest in these subjects, may partly be due to the different methodologies used in the survey designs. Further national studies exploring public understanding of science, technology and biomedicine at the national level, as well as the use of European standards, would be of great help in other cross-national studies and policies. Improving qualitative studies would also be useful to strengthen relations among science, technology and society.

  16. Spain's magic mountain: narrating prehistory at Atapuerca.

    Hochadel, Oliver

    2016-09-01

    The Sierra de Atapuerca in northern Spain is ranked among the most important excavation sites in human origins research worldwide. The project boasts not only spectacular hominid fossils, among them the 'oldest European', but also a fully fledged 'popularization industry'. This article interprets this multimedia industry as a generator of different narratives about the researchers as well as about the prehistoric hominids of Atapuerca. It focuses on the popular works of the three co-directors of the project. Juan Luis Arsuaga, José María Bermúdez de Castro and Eudald Carbonell make deliberate use of a variety of narrative devices, resonant cultural references and strategies of scientific self-commodification. All three, in different ways, use the history of science and of their own research project to mark their place in the field of human origins research, drawing on mythical elements to tell the story of the rise of a humble Spanish team overcoming all odds to achieve universal acclaim. Furthermore, the co-directors make skilful use of palaeofiction - that of Björn Kurtén and Jean Auel, as well as writing their own - in order to tell gripping stories about compassion and solidarity in human prehistory. This mixture of nationalist and universalist narratives invites the Spanish audience to identify not just with 'their ancestors' but also with the scientists, as objects and subjects of research become conflated through popularization.

    2012-06-01

    There has been increasing interest in Clostridium difficile infection (CDI) due its association with healthcare and its impact on morbidity and mortality in the elderly. During the last few years there has been a growing increase in the number of published studies on the incidence, changes on the clinical presentation and on the epidemiology, with the description of new risk factors. The frequency of CDI in Spain is not sufficiently characterised. The available data indicates that incidence is within the range of that of surrounding countries but increasing. Furthermore, the high and growing use of broad spectrum antibiotics, both in our hospitals and in the community setting, are factors that favour the increase of the disease. The hyper-virulent ribotype 027 has not spread in our hospitals. We need to know with enhanced validity and accuracy the incidence of CDI, both community and healthcare-associated, the information on outbreaks, the incidence on certain population groups, the characterisation of circulating ribotypes and the impact of the disease in terms of mortality and health costs. We need to implement programs for the improvement of antibiotic therapy in the hospital, as well as in the community. Furthermore, the knowledge and the performance of standard precautions need to be improved, particularly hand hygiene, and the specific measures to limit the transmission of C. difficile among the healthcare institutions.

    2006-03-01

    The so-called media agenda has a great influence on the issues considered to be important by society. In this article, based on the Informe Quiral (Quiral Survey), the author analyses the coverage of health issues in Spanish press. In Spain, media concentration causes a clear tendency to information homogeneity and thus, health issues are rarely dealt with in an independent way or in its own specific space or by specialized professionals. The main chronic issues the Spanish press has followed during the years included in the survey have been: cancer, sexuality and reproduction, aids, drugs (including tobacco), mental disorders and nutrition-related issues. Politicians or individuals with political and technical posts are the sources which carry the burden of informing about health issues (49%). On the other hand, the more specialized sector is the source of information in only 26% of the cases. In order to improve health information, the author suggests establishing communication platforms and closer collaboration between the specialized sector and the media, fostering mutual knowledge of all professional groups taking part in the process and ridding health information of all political influences.

  20. Core optimization studies at JEN-Spain

    International Nuclear Information System (INIS)

    Gomez Alonso, M.

    1983-01-01

    The JEN-1 is a 3-MW reactor which uses flat-plate fuel elements. It was originally fueled with 20%-enriched uranium but more recently with 90%-enriched fuel. It now appears that it will have to be converted back to using 20%- enriched fuel. Progress is presently being made in fuel fabrication. Plates with meat thicknesses of up to 1.5 mm have been fabricated. Plates are being tested with 40 wt % uranium in the fuel meat. Progress is also being made in reactor design in collaboration with atomic energy commissions of other countries for swimming pool reactors being designed or under construction in Chile, Ecuador, and Spain itself. The design studies address core optimization, safety analysis report updating, irradiation facilities, etc. Core optimization is specifically addressed in this paper. A common swimming-pool-type reactor such as the JEN-1 served as an example. The philosophy adopted in this study is not to try to match the high enrichment core, but rather to treat the design as new and try to optimize it using simplified neutronic/thermal hydraulic/economic models. This philosophy appears to be somewhat original. As many as possible of the fuel parameters are constrained to remain constant

  5. Sustainable energy communities: a study contrasting Spain and Germany

    Romero-Rubio, Carmen; Andrés Díaz, José Ramón de

    2015-01-01

    In recent years, several governments and organisations in the developed world have encouraged the creation of sustainable energy communities (SECs) as a strategy for achieving their energy and environmental targets. However, whereas in some of these countries (e.g., Germany), numerous SECs have been founded, there are other countries, such as Spain, where the creation and growth of SECs has been much slower. The purpose of this article is to analyse the case of Spain, to determine the causes of the lack of SECs in this country, and to propose actions adapted to the Spanish context aimed at accelerating the creation of SECs. To facilitate these tasks, we have taken the German case as a reference. The key finding is that, in contrast to Germany, in Spain, SECs have scarcely contributed to the development of RE (Renewable energy) infrastructures, despite having similar incentives for renewable electricity (until recently). Moreover, in Spain, these incentives have been drastically cut recently. Therefore, it has become even more difficult to finance a renewable electricity generation plant. That is why strategies in sectors other than renewable electricity have been suggested for the encouragement of SECs in Spain. -- Highlights: •Collective-ownership models for RE (Renewable energy) infrastructures are very widespread in Germany. •Approximately 22% of the installed renewable electricity capacity in Germany is owned by SECs. •In contrast, collective ownership of RE infrastructures is rare in Spain. •In Spain, incentives for renewable electricity have been drastically cut recently. •To encourage SECs, energy activities other than renewable electricity production are proposed

    The RISNA project, financed by the Emergency Agency of Navarre (Northern Spain), aims at assessing the seismic risk of the entire region. The final goal of the project is the definition of emergency plans for future earthquakes. With this purpose, four main topics are covered: seismic hazard characterization, geotechnical classification, vulnerability assessment and damage estimation to structures and exposed population. A geographic information system is used to integrate, analyze and represent all information colleted in the different phases of the study. Expected ground motions on rock conditions with a 90% probability of non-exceedance in an exposure time of 50 years are determined following a Probabilistic Seismic Hazard Assessment (PSHA) methodology that includes a logic tree with different ground motion and source zoning models. As the region under study is located in the boundary between Spain and France, an effort is required to collect and homogenise seismological data from different national and regional agencies. A new homogenised seismic catalogue, merging data from Spanish, French, Catalonian and international agencies and establishing correlations between different magnitude scales, is developed. In addition, a new seismic zoning model focused on the study area is proposed. Results show that the highest ground motions on rock conditions are expected in the northeastern part of the region, decreasing southwards. Seismic hazard can be expressed as low-to-moderate. A geotechnical classification of the entire region is developed based on surface geology, available borehole data and morphotectonic constraints. Frequency-dependent amplification factors, consistent with code values, are proposed. The northern and southern parts of the region are characterized by stiff and soft soils respectively, being the softest soils located along river valleys. Seismic hazard maps including soil effects are obtained by applying these factors to the seismic hazard maps

    Oppositional defiant disorder (ODD) is characterized by a pattern of negative, defiant, disobedient and hostile behavior toward authority figures. ODD is one of the most frequent reasons for clinical consultation on mental health during childhood and adolescence. ODD has a high morbidity and dysfunction, and has important implications for the future if not treated early. To determine the prevalence of ODD in schoolchildren aged 6-16 years in Castile and Leon (Spain). Population study with a stratified multistage sample, and a proportional cluster design. Sample analyzed: 1,049. Cases were defined according to DSM-IV criteria. An overall prevalence rate of 5.6% was found (95% CI: 4.2%-7%). Male gender prevalence=6.8%; female=4.3%. Prevalence in secondary education=6.2%; primary education=5.3%. No significant differences by gender, age, grade, type of school, or demographic area were found. ODD prevalence without considering functional impairment, such as is performed in some research, would increase the prevalence to 7.4%. ODD cases have significantly worse academic outcomes (overall academic performance, reading, maths and writing), and worse classroom behavior (relationship with peers, respect for rules, organizational skills, academic tasks, and disruption of the class). Castile and Leon has a prevalence rate of ODD slightly higher to that observed in international publications. Depending on the distribution by age, morbidity and clinical dysfunctional impact, an early diagnosis and a preventive intervention are required for health planning. Copyright © 2013 SEP y SEPB.

  10. Coal restructuring in Spain. Continuity and uncertainty?

    Rabanal, Nuria G.

    2009-01-01

    The policies of coal energy are currently undergoing a significant change. At the European Community level, energy concerns are dominated by environmental commitments that seem to demand coal's disappearance. The countries that for years have supplied the European energy market with this resource have confronted their future challenges in differing ways. The history of the energy sector in Spain has been marked by important changes, and coal has been a key factor in this process. Membership in the European Union has constituted a clear transition for a historically subsidized and protected sector that now faces an uncertain role in the national energy market. The aim of this paper is to offer an overview and analysis of the mechanisms that have been implemented in the energy sector. The first part analyzes the rationalization policies that preceded Spanish entry into the EU, giving a detailed description of the complex programs designed by the government to help mining companies. The second part analyzes later systems aimed at helping the coal industry that were implemented after the EU imposed new criteria and objectives. These systems led to the so-called 'mixed model' of rationalization. This model, which is completely different from that implemented in other member states, is based on maintaining a system of subsidies that discriminate between public and private companies. The third part examines the objectives of the current system and the plans projected for the future in the context of the EU's adoption of an energy strategy that seeks to reconcile a self-sufficient energy supply with adherence to environmental commitments.

    To estimate the overall annual incidence and age group distribution of eating disorders in a representative sample of adolescent female residents of Navarra, Spain. We studied a representative sample of 2734 adolescent Navarran females between 13 and 22 years of age who were free of any eating disorder at the start of our study. Eighteen months into the study, we visited the established centers and the eating attitudes test (EAT-40) and eating disorder inventory (EDI) Questionnaires were administered to the entire study population. We obtained a final response of 92%. All adolescents whose EAT score was over 21 points and a randomized sample of those who scored 21 or below, were interviewed. Any person meeting the DSM-IV diagnostic criteria for Anorexia Nervosa (AN), Bulimia Nervosa (BN) or eating disorder not otherwise specified (EDNOS) was considered a case. We detected 90 new cases of eating disorders. Taking into consideration the randomly selected group whose EAT score was 21 points or below, we estimated the overall weighted incidence of eating disorders to be 4.8% (95% CI: 2.8-6.8), after 18 months of observation, in which EDNOS predominated with an incidence of 4.2% (95% CI: 2.0-6.3). The incidence of AN was 0.3% (95% CI: 0.2-0.5), while that of BN was also found to be 0.3% (95% CI: 0.2-0.5). The highest incidence was observed in the group of adolescents between 15 and 16 years of age. The overall incidence of ED in a cohort of 2509 adolescents after 18 months of follow-up was 4.8% (95% CI: 2.8-6.8), with EDNOS outweighing the other diagnoses. The majority of new cases of eating disorders were diagnosed between ages 15 and 16.

    In 1984 the Empresa Nacional de Residuos Radiactivos (ENRESA) was set up in order to be responsible for all radioactive waste management activities in the country. ENRESA is a state-owned company, the shareholders of which are CIEMAT (Centro de Investigaciones Energeticas, Medioambientales y Tecnologicas, formerly (JEN) and SEPI (Sociedad Estatal de Participaciones Industriales), both institutions dependent on the Ministry of Industry and Energy. ENRESA has a broad scope of responsibilities, including not only the management of L/ILW, HLW and spent fuel but also the decommissioning of nuclear installations, as well as the rehabilitation of uranium mining and milling facilities when required. The policy on radioactive waste management is defined by the Government, and the strategies are developed by ENRESA in accordance with the General Radioactive Waste Management Plan. This Plan is a strategic document which must be submitted yearly by ENRESA to the Government, for its approval when the Ministry of Industry and Energy decided so. The plan, in general terms, contains the main aspects related to waste generation and forecasts, as well as the strategies and technical solutions to be prepared, along with the associated economic and financial aspects. ENRESA's activities are financed by the waste producers. On the one hand the nucleoelectric sector pays a percentage fee on all the electricity sales, while small producers pay tariffs according to the services provided, both are approved by the Government. The fifth General Radioactive Waste Plan, approved by the Government in July 1999, is currently in force and contains the strategies for the management of radioactive wastes and decommissioning of nuclear installations in Spain.

    To describe the current situation of gambling in Spain, sketching its history and discussing the regulations and legislation currently in force within the framework of the European Union (EU), and to review the epidemiology of gambling in Spain, the self-help groups and professional treatments available, and their potential effectiveness. A systematic computerized search was performed in three databases (EMBASE, PubMed and PsychINFO, including articles and chapters) and the reference lists from previous reviews to obtain some of the most relevant studies published up to now on the topic of pathologic gambling in Spain. Similar to other EU countries, Spain has a high prevalence of pathologic gambling, focused on specific culturally bounded types of gambling. Expenditure in online gaming has risen significantly in the last few years, prompting the Spanish government to draft new legislation to regulate gaming. The gaming industry is expected to be one of the fastest growing sectors in Spain in the coming years owing to the rise of new technologies and the development of online gaming. © 2013 Society for the Study of Addiction.

  15. Wind power development in Spain, the model of Navarra

    Wind power implementation in Spain has undergone spectacular growth in recent years. From 834 Megawatts installed at the end of 1998, the figure of 1,500 MW was reached at the end of 1999 and forecasts expect well over 2,500 MW by the end of the year 2000. A favourable legislative framework and tariff structure have brought about this rate of development, which is mainly based on the implementation of large wind farms on high altitude sites in Spain. The region of Navarra (northern Spain) has played a special role in this development, and EHN, a company born in this region, has carried out major projects that have given it 30% of the Spanish wind power sector. The challenges for the sector in Spain over the next few years are: (1) Make its development compatible with the supply guarantees required by the national electricity supply operator, (2) ensure that the implementation of wind farms is done with respect for the environment, (3) harmonise the wind power development of the different Autonomous Communities of Spain, and (4) reduce the investment costs in order to obtain enough profitability with falling energy prices in the coming years.

    (1) What is the history and the theoretical orientation of group therapy in Spain? (2) How is training organized? (3) What role does group psychotherapy play in the health system in Spain? (4) What is the relationship between group psychotherapy research and clinical practice in Spain? (5) What topics can be identified as unique to therapy groups in Spain? (6) How are group-related issues important within the social background of Spain? and (7) What does group work hold for the future? Although not even a century has passed since the birth of this discipline, there have already been many events associated with the management of power and knowledge, the development of a sense of community, and the evolution of the political and social life of our country. Group therapy training is still evolving and is properly supported and accredited by prestigious institutions. In the 2013 Symposium of the Spanish Society of Group Psychotherapy and Group Techniques (SEPTG), the need for joint group theories and techniques within the profession's activities was clearly highlighted. Further, the enthusiasm of group psychotherapists to open themselves to specific social perspectives (health, education, community prevention, organizations) is a way of encouraging society to untangle conscious and unconscious knots that are created in social interaction.

    Full Text Available This paper gathers the studies of the effects introduced when Nitrogen and Silicon were implanted in policarbonates used in optical applications. Different Nitrogen and Silicon doses were implanted for finding out the roles of this parameter in the mechanical and optical modifications. Several mechanical tests were carried out, like Microindentation, Nanoindentation and AFM. IR and UV-VIS optical tests were also carried out. Results show harder surfaces for the high Nitrogen implanted doses, and great changes in the UV-VIS spectrums.

    En el presente trabajo se estudian los efectos introducidos por la implantación de Nitrógeno atómico y Silicio sobre probetas de policarbonato empleadas para usos ópticos. Distintas dosis de Nitrógeno y Silicio fueron implantadas de cara a poner de manifiesto el efecto de la dosis sobre las propiedades ópticas y mecánicas. Se llevaron a cabo ensayos mecánicos de microdureza, nanodureza, y AFM, así como ensayos ópticos de Reflexión-absorción IR y Transmitancia UV-VIS. Los resultados muestran un endurecimiento superficial para las implantaciones a dosis altas de Nitrógeno, así como cambios considerables en los espectros de transmitancia.

    Full Text Available A irreverência e a criticidade de alguns rappers e o gingar alegre do corpo erótico proposto pelo funk sugerem um novo cenário para as metrópoles do país, em que a pluralidade da arte juvenil surge como forma de enfrentamento das marcas deixadas por fraturas sociais profundas. Os conceitos de "visão dionisíaca de mundo", "estética extrema" e "transvaloração dos valores", de Nietzsche, e o "erotismo", segundo Bataille, nortearam o método de ruptura de campo, concebido por Herrmann. Este, essencial para se repensar as noções de autoridade e tradição na sociedade contemporânea a partir das ideias veiculadas pelo rap e pelo funk. Consideramos que somente uma etnografia do olhar que apanhe a dimensão erótica e irreverente - a "eróptica", segundo Canevacci - destas manifestações poderia nelas identificar uma estética afirmativa e crítica, como diria Nietzsche, capaz de produzir uma verdadeira reversão dos valores em nossa sociedade e, no caso, no interior da própria escola.

    Full Text Available Resumen La guerra del Pacífico (1879-1884 que enfrentó a Perú y Bolivia contra de Chile, representa un conflicto armado marcado por las políticas realistas de imponer el interés nacional, frente a otros Estados, alterando el equilibrio político regional, bajo la justificación de las reivindicaciones territoriales. Esta política no sólo afectó a los beligerantes, sino que a otros países que pudieron sumarse en la confrontación buscando cambiar su status quo. Ecuador representa esta consideración, en cuanto a que su participación pudo consolidar su frontera sur con Perú, pendiente desde de la emancipación. ¿Fue la debilidad política interna la que no permitió concretar una posible intervención? En las siguientes páginas se estudiará este proceso histórico, desde la óptica del realismo clásico presente en las relaciones internacionales, donde el escenario interno de un país, es determinante en la proyección de su política exterior.

Os participantes compararam pesos colocados sobre as palmas das mãos e, conforme a condição experimental, podiam movimentar ou não os braços, bem como visualizar ou não suas mãos e os estímulos. Os resultados mostraram que a precisão e a sensibilidade foram influenciadas pelo movimento e, em menor grau, pela visão. Em geral, o movimento leva à maior precisão e mais sensibilidade, e a contribuição da visão ocorreu nas condições sem movimento. O nível de confiança não foi influenciado pelo movimento, mas foi influenciado pela visão, sobretudo nas condições sem movimento. O nível de confiança foi congruente à precisão dos julgamentos somente na ausência de visão, sugerindo um conhecimento implícito da precisão.

    Full Text Available At the beginning of the 21st century Spain faced a number of challenges, primarily the growth of separatist sentiments in the regions fraught with the danger of its fragmentation on ethno-national basis. In the context of increased ethno-national mobilization of “small peoples” in Spain one of its most economically developed regions – Catalonia – envisages a rise of the regional identity. Against the backdrop of economic problems generated by the crisis of 2008-2014 the autonomous communities of Spain, including Catalonia, came across the rise of socio-political problems, particularly the growing distance between the society and the central administrative bodies formed in democratic conditions, as well as the two-party administrative system.

  7. Eating out in Spain: Motivations, sociability and consumer contexts.

    Díaz-Méndez, Cecilia; García-Espejo, Isabel

    2017-12-01

    Eating out is a consumer practice which is difficult to define. The study of this practice has traditionally been based on the work/leisure dichotomy. However, in Spain this is not so clear. If we analyse profiles, motivations, places and relationships, we discover an eating-out food model which is specific to Spain and in which food is not limited by this dual link with work and leisure. Eating linked to work does not respond only to instrumental needs. Leisure eating is not always a choice based on preference. Both contain a strong element of sociability which acts as a motivator and are linked to the familisme of Spanish society, whilst at the same time de-routinizing daily life, both at home and at work. This study is based on a national survey carried out in 2014 and helps to understand this consumer practice and those elements which are specific to Spain. Copyright © 2017 Elsevier Ltd.

    Full Text Available During the first third of the 20th century, Spanish migrants in Argentina prompted, from specific areas of civil society and the public sphere, corporate identity for political purposes. It was a residual patriotism and condemned from the outset. It was activated in specific circumstances and in relation to the local policies projected towards the collective migratory, the Spanish politics, and recognition of shared sociopolitical and cultural genealogies. From the perspective of cultural history of the policy, and based on primary and secondary sources, this article discusses about built imaginaries, social mobilization generated and results between 1885 and 1920. During that time, from distance, migrants also built ideas about Spain and drawn up national myths in the cultural version of liberalism that eventually led to a conservative nationalist, catholic and –at times– fascist.

    The aim of this study was to analyse trends of births in Spain and its Autonomous Communities (CCAA) over a 70 year period (1941-2010). The crude birth rates per 1,000 inhabitants/year were calculated by CCAA using Joinpoint regression models. Change points in trend and annual percentage of change (APC) were identified. The distribution of 38,160,305 births between 1941 and 2010 shows important changes in trends both nationally and among the CCAA. There is a general pattern for the whole country, with 5 turning points being identified with changes in trend and annual percentage change (APC). Differences are also found among regions. The analysis of trends in birth rates and the annual rates of change should enable public health authorities to properly plan pediatric care resources in our country.

    Epidemiological studies in many regions and countries have contributed to determining the epidemiology of type 1 diabetes (T1DM) in children less than 15 years old. Studies in many regions of Spain have been published, but the national incidence is not really known. A review was made of the publications on the epidemiology of T1DM in Spain, selecting the references on patients less than 15 years old. Many epidemiological studies on T1DM in almost all regions in Spain have been published. The methodology of these studies is heterogeneous, with variations in geographical definition, duration, period of study, limit of age, and data collection. The incidence rates are variable, from 11.5 cases per 100,000/year in Asturias to 27.6 in Castilla-La Mancha. Some studies report the percentage of diabetic ketoacidosis at the time of diagnosis, which is usually in the range of 25-40%. Although there have been various epidemiological studies on T1DM in almost all regions in Spain, the methodology is heterogeneous. The mean incidence of T1DM in children less than 15 years old in Spain, stimated from the selected studies is 17,69 cases per 100,000/year. T1DM registers need to be created and updated, using standardized methodology, to get more reliable data of the epidemiology of T1DM in Spain in the near future.

    Spain's plummeting fertility since the late twentieth century may seem to reflect a waning desire for children. Nevertheless, reproductive disappointments resulting from gender inequalities cause many Spanish women to postpone motherhood and experience age-related fertility problems. For them, creating a family often becomes possible only through the reproductive labor of other women. Our analysis of transnational adoption, egg donation, and surrogacy in Spain shows how anonymity and altruism play out in these three strategies, with implications for the valuation of women's reproductive work and relationships among reproductive providers, intermediaries, recipients, and the resulting children.

    This article studies the links between psychoanalysis and the transition to democracy in Spain. It examines the major changes that characterized the spread of psychoanalysis in the years after Franco's death, in particular the rise of the Lacanian movement, the impact of this phenomenon on the sociocultural sphere and, in broader terms, its role in the re-emergence of psychoanalysis as a cultural object in the country. The article also analyzes factors linked to the history of psychoanalysis during the Franco dictatorship; factors that, together with the arrival of Oscar Masotta and numerous Argentinian analysts in Spain, help explain the new vision of the field that emerged during the transition.

    Official figures submitted in 2002 showing the trends of greenhouse gases during the period 1990-2000 indicate that Spain is a long way from attaining its commitments with the international and national programmes on climate change. Both structural and cultural factors are used to explain the evolution in climate politics and the growth of its emissions with particular emphasis given to the lack of public participation in this respect. It is also argued that Spain will have either to buy emission reductions abroad or/and find new ways to reduce greenhouse gases in a more decentralised manner in tune with its current Autonomous Communities' (ACs) political organisation

    Droughts are long-term phenomena affecting large regions causing significant damages both in human lives and economic losses. The use of remote sensing has proved to be very important in monitoring the growth of agricultural crops and trying to asses weather impact on crop loss. Several indices has been developed based in remote sensing data being one of them the normalized difference vegetation index (NDVI). In this study we have focus to know the correlation between NDVI data and the looses of rain fed cereal in the Spanish area where this crop is majority. For this propose data from drought damage in cereal come from the pool of agricultural insurance in Spain (AGROSEGURO) including 2007/2008 to 2011/2012 (five agricultural campaigns). This data is given as a ratio between drought party claims against the insured value of production aggregated at the agrarian region level. Medium resolution (500x500 m2) MODIS images were used during the same campaigns to estimate the eight-day composites NDVI at these locations. The NDVI values are accumulated following the normal cycle of the cereal taking in account the sowing date at different sites. At the same time, CORINE Land Cover (2006) was used to classify the pixels belonging to rain fed cereal use including a set of conditions such as pixels showing dry during summer, area in which there has been no change of use. Fallow presence is studied with particular attention as it imposes an inter annual variation between crop and bare soil and causes decreases in greenness in a pixel and mix both situations. This is more complex in the situation in which the avoid fallow and a continuous monoculture is performed. The results shown that around 40% of the area is subject to the regime of fallow while 60% have growing every year. In addition, another variation is detected if the year is humid (decrease of fallow) or dry (increase of fallow).

  1. [Tarantism in Spain in the eighteen century: latrodectism and suggestion].

    Science.gov (United States)

    Corral-Corral, I; Corral-Corral, C

    2016-10-16

    Tarantism is the disease caused by the bite of the tarantula, in which the music tarantella triggers an involuntary dance. It is known in Italy since the sixteenth century. To analyze the tarantism reported in Spain at the end of the eighteenth century, with special attention to its neurological aspects, and to propose its medical and psychopathological explanation. An epidemic of people affected by the tarantula bite occurred in Spain in 1782. Spanish doctors described appropriately the clinical effects, identical to those produced by the bite of the spider black widow (Latrodectus tredecimguttatus), which was at that time identified as a tarantula. The cases reported by Francisco Xavier Cid cured with the involuntary dance triggered by the tarantella, as was described in Italy since the sixteenth century. Our interpretation is that this curative effect of dance in Spain was induced by suggestion. In Spanish patients there were no behavioral disturbances, periodic recurrences or collective involvement as those reported by Italian authors, which suggest an hysterical phenomenon, probably a continuation of the dancing mania of the Middle Age. Tarantism reported in Spain in the eighteenth century includes two different phenomena: the systemic symptoms produced by the tarantula bite, which is actually latrodectism, and the curative effect of the tarantella, explained by suggestion. The psychiatric disturbances, with a hysterical nature, falsely associated to the tarantula bite, observed in Italy, were not present among the Spanish cases of tarantism in the eighteenth century.

    Despite the growing recognition of the potential applications of cost-effectiveness assessments, a criterion to establish what is an efficient health technology does not exist in Spain. The objective of this work is to describe the limits and the criteria used in Spain to recommend the adoption of health interventions. A review of the economic evaluations of health technologies published in Spain from 1990 to 2001 was conducted. Complete economic assessments in which the cost-effectiveness ratio was expressed as cost per life-year gained (LYG), cost per quality-adjusted-life-year (QALY) or cost per saved live were selected. Those interventions in which the authors established recommendations (adoption or rejection) and the criteria used were analyzed. Twenty (20%) of the 100 complete economic evaluations fulfilled the selection criteria. In16 studies, the results were expressed as cost per LYG, in 6 studies as cost per QALY and in 1 as cost per saved live. A total of 82 health interventions were assessed and some kind of recommendation was established in 44 of them. All technologies with a cost-effectiveness ratio lower than 30,000 euros (5 million pesetas) per LYG were recommended for adoption by the authors. Up to that limit there was no a clear tendency. Although the results must be interpreted with much precaution, given the limitations of the study, the limits of cost-effectiveness presented in this work could be a first reference to which would be an efficient health intervention in Spain.

  7. Investigating the reasons for Spain's falling birth rate.

    Science.gov (United States)

    Bosch, X

    1998-09-12

    On August 25, 1998, the Spanish National Institute of Statistics announced that Spain, which has had the most accelerated decrease in fecundity of all European countries during the last 25 years, had the lowest birth rate in Europe. Spain's average birth rate was 2.86 in 1970, 2.21 in 1980, and 1.21 in 1994. According to Eurostat, Spain's average birth rate in 1995 was 1.18, while the European Community's was 1.43. Although all the countries of the European Community have birth rates below 2.1, Spain's is 44% below this minimum rate needed to achieve generation replacement. In 1994 and 1997, in 5 northern communities, including the Basque country and Galicia, the birth rate was less than 1.0. The lowest birth rate (0.76 in 1997) was in the northern region of Asturias. Although southern autonomous regions have higher birth rates (between 1.21 and 1.44 for 1997) than northern ones, these are also decreasing (from 3.36 in 1970 to 1.29 in 1997 in Andalusia). Credit for the rapid decrease is given to improved quality of life and education, increased contraceptive usage, and social change. Employment of women has increased, and unemployed sons are remaining at home for longer periods. The most important reasons are 1) the increased number of single people and 2) the increased average age of women having their first child. The latter increase began in 1988. Most Spanish women now have their first child between the ages of 30 and 39 years. The average age was 28 years in 1975; in 1995, it was 30 years. Women from the northern autonomous regions have the highest average age at first birth (Basque women, 31.2 years in 1995). The pattern of fecundity in Spain is different from other countries in Europe. In Spain, the decrease started in the late 1960s and early 1970s. Until the 1980s, Spain had one of the highest birth rates in Europe. This was followed by a decrease in the 1990s. However, in 1997, there were 3000 more births than in 1996.

  8. International Uranium Resources Evaluation Project (IUREP) national favourability studies: Spain

    International Nuclear Information System (INIS)

    1977-10-01

    Spain, with an area of 504 748 km''2, occupies a large part of the Iberian Peninsula. At present the country appears to have about 6300 t of reasonably assured uranium reserves and 8500 t of additional estimated reserves (all at less than $30/lb of U 3 O 8 ). Spain has devoted some $33 million to prospecting for uranium since the beginning of such work. Most of the reasonably assured reserves are located in ores impregnating Cambrian schists intersected by Hercynian granites (of so-called 'Iberian type'); a small amount, however, is found in veins in Hercynian granites of the Spanish Meseta. The additional estimated reserves are situated in the peripheral post-Hercynian continental basins of the Meseta. Apart from these classical ores, sub-ores have been identified in Silurian quartzites with low concentrations of uranium associated with refractory minerals, totalling more than 200,000 t of U (at concentrations of a few hundred ppm); there are likewise uranium-bearing Oligocene lignites in the Ebro Basin with some 140,000 t of U. These facts, and also the very wide distribution of uranium in space and time (from the Cambrian to the Miocene!) and the country's favourable geological characteristics, suggest that Spain ought in fact to have large reserves of uranium, a conclusion unfortunately belied by the paucity of the economic reserves identified so far. Two things must be borne in mind, however; firstly, Spain's financial outlay for uranium prospecting up till now represents only a quarter of what has been invested in France, for example, and, secondly, the nature of the mineralised bodies in Spain makes exploration difficult. In conclusion it seems that prospecting both of the Iberian-type deposits in the Meseta region and of the deposits associated with detrital sediments in the peripheral continental basins - especially blind mineralized bodies - should hold out excellent prospects for Spain. Consequently we propose that Spain should be placed at least in

    Full Text Available Introducción: existen diversos criterios en cuanto a la identificación de los pacientes con sangrado digestivo alto que requieren tratamiento quirúrgico de urgencia, dada la alta tasa de letalidad y mortalidad que presentan. Objetivo: valorar la mortalidad por hemorragia digestiva alta asociada a enfermedad ácido péptica. Métodos: se realizó una investigación descriptiva de 38 pacientes que habían sido operados por hemorragia digestiva asociada a enfermedad ácido péptica, que fallecieron en el Hospital Provincial Docente Clinicoquirúrgico "Saturnino Lora Torres" durante el decenio 2002-2011. Resultados: en la casuística se encontró un predominio del sexo masculino y del grupo etario de 60 y más años. Los sangrados masivo y persistente constituyeron las situaciones más comunes para decidir el tratamiento quirúrgico urgente. La vagotomía troncular más piloroplastia fue la técnica más empleada, en tanto la infección respiratoria y el choque séptico resultaron ser las principales complicaciones posoperatorias; este último y la disfunción multiorgánica fueron las causas directas de muerte más representativas. Conclusiones: para seleccionar la técnica quirúrgica en cada paciente debe tenerse en cuenta la causa del sangrado, la localización, el estado clínico y la edad. La vagotomía troncular asociada a algún procedimiento de drenaje resultó la más utilizada porque es menos laboriosa y el efecto antiácido más efectivo.Introduction: there are several criteria regarding the identification of patients with upper gastrointestinal bleeding who require emergency surgical treatment because of their high lethality and mortality rate.

    Full Text Available The total leaf area (TLA estimation is an important feature of the crops and their assessment a challenge, since the direct methods of obtaining it are destructive and time consuming. Non-destructive methods have been explored to obtain the TLA by indirect approaches, in turn creating other features, as the leaf area index. The development of non-destructive technology to access the TLA of a plant has been the subject of much research, and the optical metrology is an promising approach. In this work, some indirect methods associated with optical approaches were evaluated as an alternative to obtain the TLA of the coffee plant. Commercial equipment were used, such as a camera with a fish eye lens and lux meters, associated to the sizes of the canopies were tested and compared to another non-destructive method and with methods proposed in the literature. The association between production and the TLA estimated was also evaluated. The results showed that the commercial equipment, generally used in forestry, was not the best approach in coffee plants, and that the methods related to the size and lux values of the plants were the best alternatives to estimate the TLA of the coffee plant.A estimativa da área foliar total (AFT é uma importante característica das culturas cuja avaliação é um desafio visto que métodos diretos de obtê-la são destrutivos e consome tempo. Métodos não destrutivos têm sido explorados com vista a se obter a AFT por meio de abordagens indiretas e, por sua vez, a criação de outros recursos, como o índice de área foliar. O desenvolvimento de tecnologia não destrutiva para acessar a AFT de uma planta tem sido objeto de muitas pesquisas e a metrologia óptica é uma abordagem promissora. Neste trabalho alguns métodos indiretos associados com as abordagens ópticas foram avaliados como alternativa para obtenção da AFT do cafeeiro.

    Full Text Available The analysis of the temporal lobe seizures through video-EEG systems shows that they often consist of a sequence of clinical and EEG features which may suggest the localization and the lateralization of the epileptogenic lobe. We analyzed clinical and EEG features of 50 temporal lobe seizures which were separated in group 1 with 25 patients (related to mesial temporal sclerosis and group 2 with 25 patients (other neocortical temporal lesions. Among the auras, the epigastric type was the most frequent and predominated in group 1. There were differences between the two groups, considering dystonic and tonic posturing and versive head and eye movements. Dystonic posturing was always contralateral to the ictal onset and was considered the most useful lateralizing clinical feature. Ictal speech, spitting and blinking automatisms, prolonged disorientation for place and a greatest percentage of postictal language preservation occurred in right temporal seizures. Postictal aphasia and global disorientation predominated in left temporal seizures. EEG was important for lateralizing the epileptogenic lobe, specially considering rhythmic ictal activity and postictal findings.As crises epilépticas do lobo temporal tendem a seguir uma sequência previsível de eventos clínicos e eletrencefalográficos, cuja análise, preferencialmente através de sistemas de vídeo-EEG, sugere a localização e a lateralização do lobo epileptogênico.

    Diego Fernando Navas

    Full Text Available Los transformadores son elementos de suma importancia dentro de las redes eléctricas. Su vida útil depende, entre otros factores, de la temperatura presente en su interior, especialmente aquella localizada en sus materiales aislantes. Dichas temperaturas suelen ser estimadas a través de modelos propuestos en las normatividades; sin embargo, los valores obtenidos son aproximados y siempre es deseable obtener una medición directa. Por razones netamente económicas la medición directa suele emplearse en transformadores de potencia. Sin embargo, con la llegada de las smarts grids (redes inteligentes será necesaria la instrumentación en los sistemas de distribución y el uso de tecnologías más limpias. Con fines investigativos, en el presente documento los autores comentan sus experiencias en la instrumentación con fibras ópticas de cuatro transformadores de distribución sumergidos en aceite mineral y vegetal para realizar una evaluación térmica. Los transformadores tienen capacidades de 15 kVA y 37,5 kVA y operan a tensiones de 7620 V / 240 V. Se explica el proceso de determinación de los puntos de medición de temperatura al interior del transformador y se finaliza con resultados de ensayos de elevación de temperatura empleando carga simulada mediante cortocircuito y carga real a dos niveles para comparar las mediciones dentro de cada uno de los transformadores.

Apresentam uma observação anátomo-clínica de mielo-patia neuro-óptica com artério e arteriolosclerose, em que a doença se iniciou pelo acometimento do nervo óptico direito, e, somente dois meses depois, surgiram os primeiros sinais de acometimento da medula espinal. No quarto mês de doença estabeleceu-se, de modo completo, o quadro medular, com uma sindrome motora tetraplégica pirâmido-extrapiramidal, outra motora primária nas extremidades distais dos membros superiores, por acometimento das pontas anteriores e, finalmente, uma sindrome sensitiva de tipo cordonai, abrangendo todas as formas de sensibilidade, a partir de C3. A enfermidade evoluiu em 12 meses, ocorrendo a morte em conseqüência de insuficiência respiratória de origem bulbar provável. O exame anátomo-patológico mostrou atrofia e esclerose total dos nervos ópticos, discretos infiltrados parvicelulares em torno de alguns vasos intracerebrais e piais e, na medula, um quadro histopatológico comparável ao que de regra se encontra na oftalmoneuromielite; apenas, no segmento cervical, onde as lesões eram muito extensas, havia foco de amolecimento mais pronunciado do que aqueles que se observam mais freqüentemente. 0 fato talvez decorra de esclerose arterial concomitante existente neste caso. Havia, também, lesões bulbares discretas.

    Continuous population aging has raised international policy interest in promoting active aging (AA). AA theoretical models have been defined from a biomedical or a psychosocial perspective. These models may be expanded including components suggested by lay individuals. This paper aims to study the correlates of AA in three European countries, namely, Spain, Poland, and Finland using four different definitions of AA. The EU COURAGE in Europe project was a cross-sectional general adult population survey conducted in a representative sample of the noninstitutionalized population of Finland, Poland, and Spain. Participants (10,800) lived in the community. This analysis focuses on individuals aged 50 years old and over (7,987). Four definitions (two biomedical, one psychosocial, and a complete definition including biomedical, psychosocial, and external variables) of AA were analyzed. Differences in AA were found for country, age, education, and occupation. Finland scored consistently the highest in AA followed by Spain and Poland. Younger age was associated with higher AA. Higher education and occupation was associated with AA. Being married or cohabiting was associated with better AA compared to being widowed or separated in most definitions. Gender and urbanicity were not associated with AA, with few exceptions. Men scored higher in AA only in Spain, whereas there was no gender association in the other two countries. Being widowed was only associated with lower AA in Poland and not being married was associated with lower AA in Poland and Finland but not Spain. Associations with education, marital status, and occupation suggest that these factors are the most important components of AA. These association patterns, however, seem to vary across the three countries. Actions to promote AA in these countries may be addressed at reducing inequalities in occupation and education or directly tackling the components of AA lacking in each country.

  2. Crisis, suicide and labour productivity losses in Spain.

    Suicide became the first cause of death between the ages of 15 and 44 in Spain in the year 2013. Moreover, the suicide rate in Spain went up by more than 9 % with respect to the previous year. This increase could be related to the serious economic recession that Spain has been experiencing in recent years. In this sense, there is a lack of evidence to help assess to what extent these suicides have a social cost in terms of losses in human capital. Firstly, this article examines the relationship between the variables related to the economic cycle and the suicide rates in the 17 Spanish regions. Secondly, an estimate is made of the losses in labour productivity owing to these suicides. In this article, panel data models are used to consider different variables related to the economic cycle. Demographic variables and the suicide rates for regions across Spain from 2002 to 2013 also come into play. The present and future production costs owing to premature death from suicide are calculated using a human capital model. These costs are valued from the gross salary that an individual no longer receives in the future at the very moment he or she leaves the labour market. The results provide a strong indication that a decrease in economic growth and an increase in unemployment negatively affect suicide rates. Due to suicide, 38,038 potential years of working life were lost in 2013. This has an estimated cost of over 565 million euros. The economic crisis endured by Spain in recent years has played a role in the higher suicide rates one can observe from the data in official statistics. From a social perspective, suicide is a public health problem with far-reaching consequences.

    The main aim of this report is to present a picture of the current organization of nephrology in Spain. The Spanish health system offers almost universal coverage, a wide variety of services and a high-quality network of hospitals and primary care centers. Spain has a specialized health care training system that is highly developed, highly regulated, with the capacity to provide high-quality training in 54 different specialties. Nephrology is basically a hospital-based specialty. There are no private dialysis patients in Spain. Hemodialysis centers are 40% public, 15% private and 45% run by companies. The National Health System covers 95% of the population, and there is no cost to patients for treatment of renal disease (dialysis and transplant). We observed a clear decrease of nephrology in residents' election rankings, with position 29 out of 47 specialties in 2007. Some of the reasons for this are the complexity of the subject, no clear information at the university, reduction of professional posts and a very good public service with minimal private practice. In Spain, a model of organization for transplantation was adopted based on a decentralized transplant coordinating network. For cadaveric donors, it compares favorably with rates in other Western countries. Living donor transplantation is very low in Spain--just 10% of total renal transplantation activity. New programs due to financial constraints need to include reduced dialysis costs, greater cost-effectiveness of prescriptions, better handling of ethical issues related to the need for using a clinical score of chronic kidney disease patients to make decisions about conservative or renal replacement therapy and an action plan for improvement of organ donation and transplantation. Recovery of skills (acute kidney injury, biopsies, vascular access, etc.), research and advances in autonomous activities (imaging, surgical and medical vascular training, etc.) are some of the future educational paths needed in

Se realizó un estudio descriptivo y retrospectivo de los pacientes con enfermedad ulceropéptica complicada tratados mediante exéresis. Los pacientes (45 en total fueron atendidos por alguno de los autores, en el Hospital Provincial Clinicoquirúrgico «Amalia Simoni», en Camagüey, entre enero de l989 y diciembre del 2004. RESULTADOS. La enfermedad se presentó con mayor frecuencia en el sexo masculino (82,22 % y en las edades comprendidas entre 36 y 50 años (46,67 %. El 95,56 % de los pacientes tratados padecían úlcera duodenal, y la principal indicación para la cirugía fue la intratabilidad (62,22 %. La endoscopia (84,44 % resultó ser muy útil para el diagnóstico de esta afección. A todos los operados se le realizó vagotomía con antrectomía; en el 68,89 % la anastomosis fue de Billroth II, y en el resto de los pacientes (31,11 % fue del tipo Billroth I. Se observó igual cantidad de complicaciones precoces en las técnicas realizadas, y entre ellas prevalecieron el sangrado de la anastomosis y el retardo de la evacuación. Se detectaron más complicaciones tardías en la anastomosis de tipo Billroth II que en la de Billroth I. Los resultados quirúrgicos fueron excelentes y muy buenos en el 89 % de los casos. La variante antecólica registró el mayor porcentaje de resultados no satisfactorios (9,09 %. Solo en dos pacientes se obtuvieron resultados malos, aunque no hubo mortalidad operatoria. CONCLUSIONES. Este tipo de cirugía tiene indicación solo en casos de úlcera péptica complicada. No es el método de elección en pacientes ulcerosos, pero su uso requiere conocer las diferentes técnicas y saber utilizarlas.

    Full Text Available Foi demonstrado recentemente que o complexo de histocompatibilidade principal de classe I (MHC I, expresso no sistema nervoso central (SNC, não funciona somente como molécula com papel imunológico, mas também como parte de um mecanismo envolvido na plasticidade sináptica. A expressão de MHC I interfere na intensidade e seletividade da retração de sinapses em contato com neurônios que sofreram lesão e também influencia a reatividade das células gliais próximas a esses neurônios. A intensidade do rearranjo sináptico e resposta glial após lesão, ligadas à expressão de MHC I no SNC, repercute em diferenças na capacidade regenerativa e recuperação funcional em linhagens de camundongos isogênicos. Dessa forma, os novos aspectos sobre a função do MHC I no SNC direcionam futuras pesquisas no sentido de buscar o envolvimento do MHC I em doenças neurológicas e também o desenvolvimento de novas estratégias terapêuticas.El complejo mayor de histocompatibilidad de clase I (MHC I, expresado en el sistema nervioso central (SNC, no sólo funciona como una molécula con función inmunológica, sino que es crucial para las respuestas del tejido nervioso en casos de lesiones. El MHC I está involucrado con los procesos de plasticidad sináptica y las células gliales en el microambiente de la médula espinal después de realizada axotomía periférica. La expresión de MHC I interfiere con la intensidad y la forma en que se producen la contracción y la eliminación de sinapsis con relación a las neuronas, cuyos axones se han comprometido, y también influye en la reactividad de las células gliales, cerca de estas neuronas. La intensidad de estos cambios, que responden a la expresión de MHC I en el SNC, implica diferencias en la capacidad de regeneración axonal de las células dañadas por axotomía, por lo que el nivel de expresión de las moléculas MHC I se relaciona con el proceso de regeneración de los axones y, en

    Malaria was one of the most important public health problems of the Colonial Medicine and, for this reason, the subject was reflected in the Spanish medical journalism. The aim of the paper was to reconstruct the Spanish contributions to international health during the first half of the twentieth century. The primary sources of information on malaria were the medical journals Medicina de los Países Cálidos and Medicina Colonial, between 1929 and 1954. The documents were classified according to the sections of the magazine and its contents were studied, framing them in the history of international public health. In primary sources were found 466 documents. Malaria was one of the major diseases of the Spanish Protectorate in Morocco and Spanish Guinea, favoured by the occupation of the Spanish army. Antimalaria campaigns included strategies such as the use of Dichloro-diphenyl-trichloroethane, preventive education and massive quininización. Malariology in the specialized journalism, experienced a growing boom. The most outstanding authors in magazines analyzed were Gustavo Pittaluga, Sadí de Buen, Eliseo de Buen and Juan Gil-Collado. The Spanish specialized journalism provides the importance e interaction in antimalaria campaigns in Spain and Spanish African colonies of scientific, professional, political and military factors. The colonial situation was negative and marked differences between metropolis and colonies in terms of the effort, efficiency and the different temporal sequence of the measures undertaken.

    Full Text Available Abstract Background Information on the genotypic diversity of Coxiella burnetii isolates from infected domestic ruminants in Spain is limited. The aim of this study was to identify the C. burnetii genotypes infecting livestock in Northern Spain and compare them to other European genotypes. A commercial real-time PCR targeting the IS1111a insertion element was used to detect the presence of C. burnetii DNA in domestic ruminants from Spain. Genotypes were determined by a 6-loci Multiple Locus Variable number tandem repeat analysis (MLVA panel and Multispacer Sequence Typing (MST. Results A total of 45 samples from 4 goat herds (placentas, N = 4, 12 dairy cattle herds (vaginal mucus, individual milk, bulk tank milk, aerosols, N = 20 and 5 sheep flocks (placenta, vaginal swabs, faeces, air samples, dust, N = 21 were included in the study. Samples from goats and sheep were obtained from herds which had suffered abortions suspected to be caused by C. burnetii, whereas cattle samples were obtained from animals with reproductive problems compatible with C. burnetii infection, or consisted of bulk tank milk (BTM samples from a Q fever surveillance programme. C. burnetii genotypes identified in ruminants from Spain were compared to those detected in other countries. Three MLVA genotypes were found in 4 goat farms, 7 MLVA genotypes were identified in 12 cattle herds and 4 MLVA genotypes were identified in 5 sheep flocks. Clustering of the MLVA genotypes using the minimum spanning tree method showed a high degree of genetic similarity between most MLVA genotypes. Overall 11 different MLVA genotypes were obtained corresponding to 4 different MST genotypes: MST genotype 13, identified in goat, sheep and cattle from Spain; MST genotype 18, only identified in goats; and, MST genotypes 8 and 20, identified in small ruminants and cattle, respectively. All these genotypes had been previously identified in animal and human clinical samples from several

    Chronic consumption of water, which contains contaminants, may give rise to adverse health effects. The Madrid region, covered by the population-based multicase-control (MCC-Spain) study, includes two drinking water supply areas. The different sources of the water, coupled together with the possible differences in water management, mean that there may be differences in drinking water quality. In the context of the MCC study, our aims were to describe contaminant concentrations in tap water drawn from various sampling points distributed around the region, assess these concentrations by reference to guideline values and study possible differences between the two supply areas. Tap water samples were collected from 34 sampling points in 7 towns in the Madrid region (19-29 April 2010), and 23 contaminants (metals, nitrates, disinfection by-product and Mutagen X levels) were quantified. We undertook a descriptive analysis of the contaminant concentrations in the water and compared them between the two water supply areas (Wilcoxon test). We created maps representing the distribution of the concentrations observed at water sampling points and assessed the correlations (Spearman's coefficient) between the different parameters measured. The concentrations of the contaminants were below guideline values. There were differences between the two supply areas in concentration of nitrates (p value = 0.0051) and certain disinfection by-products. While there were positive correlations (rho >0.70) among some disinfection by-products, no correlations were found in metals or nitrates. The differences in nitrate levels could be linked to differences in farming/industrial activities in the catchment areas and in disinfection by-products might be related to the existence of different treatment systems or bromine content in source waters.

This situation is explained by the economical contexts thatevolve from the agricultural sector to the industrial development of certain zones, which are those who have a better network of vocational schools. In this article three levels of analysis are addressed: the first one, related to the politics and educational legislation, in order to notice the process of formalization; the second one, focused on the relevance of the Church on this sector and, the third one is the role played by the Union Organization during the Franco's regime. In this way, the intervention of the different agents who have contributed to the development of the vocational training in Spain remains clear up to the General Law of Education of 1970.

  14. The judicialization of territorial politics in Brazil, Colombia and Spain

    Directory of Open Access Journals (Sweden)

    Helder Ferreira do Vale

    2013-08-01

    Full Text Available This article explains how judicial review influences intergovernmental political dynamics in Brazil, Colombia and Spain. The argument is developed in light of two questions: how supreme courts have established themselves as pivotal institutions for settling vertical intergovernmental disputes, and how national and subnational politicians use judicial review in order to enhance their own interests. A comparison between the judicial review processes in federal Brazil, quasi-federal Spain, and unitary Colombia provides an answer to these questions. Accounting for the differences in the territorial organization and systems of government among these countries, the article assesses the patterns of judicial review originating from the subnational level. Findings suggest that courts affect the interaction between national and subnational politicians in the three country-cases, but through different patterns of judicialization of territorial politics.

    The objective of this report is to describe the Spanish energy policies related to renewable energy sources (RES). It will contribute to the analysis of the renewable energy potential at the European level (RES2020 project). Despite the successful case of wind development in spain, with a favourable feed-in systems in place, and a very favourable regulation (building code) promoting solar thermal technologies, strong administrative barriers for RES projects still exist and Spain is still far from reaching its RES electricity targets, and even further from the target related to RES heating and cooling and bio fuel use.

  16. Analysis of Official Suicide Statistics in Spain (1910-2011

    Directory of Open Access Journals (Sweden)

    2017-01-01

    Full Text Available In this article we examine the evolution of suicide rates in Spain from 1910 to 2011. As something new, we use standardised suicide rates, making them perfectly comparable geographically and in time, as they no longer reflect population structure. Using historical data from a series of socioeconomic variables for all Spain's provinces and applying new techniques for the statistical analysis of panel data, we are able to confirm many of the hypotheses established by Durkheim at the end of the 19th century, especially those related to fertility and marriage rates, age, sex and the aging index. Our findings, however, contradict Durkheim's approach regarding the impact of urbanisation processes and poverty on suicide.

    2014-01-01

    Tularemia outbreaks occurred in northwestern Spain in 1997–1998 and 2007–2008 and affected >1,000 persons. We assessed isolates involved in these outbreaks by using pulsed-field gel electrophoresis with 2 restriction enzymes and multilocus variable number tandem repeat analysis of 16 genomic loci of Francisella tularensis, the cause of this disease. Isolates were divided into 3 pulsotypes by pulsed-field gel electrophoresis and 8 allelic profiles by multilocus variable number tandem repeat analysis. Isolates obtained from the second tularemia outbreak had the same genotypes as isolates obtained from the first outbreak. Both outbreaks were caused by genotypes of genetic subclade B.Br:FTNF002–00, which is widely distributed in countries in central and western Europe. Thus, reemergence of tularemia in Spain was not caused by the reintroduction of exotic strains, but probably by persistence of local reservoirs of infection. PMID:24750848

    2017-04-01

    This research examines the evolution of nuclear technology in Spain from the early years of the Franco dictatorship to the global financial crisis and technology's influence on Spanish culture. To this end, we take a sociological perspective, with science culture and social perceptions of risk in knowledge societies serving as the two elements of focus in this work. In this sense, this article analyses the transformation of social relationships in light of technological changes. We propose technology as a strategic place to observe the institutional and organisational dynamics of technologic-scientific risks, the expert role and Spain's science culture. In addition, more specifically, within the language of co-production, we 'follow the actor' and favour new forms of citizen participation that promote ethics to discuss technological issues.

    Martín-Fernández, Luis; Martínez-Núñez, Margarita

    2011-08-01

    Soil erosion is one of the most important factors in land degradation and influences desertification worldwide. In 2001, the Spanish Ministry of the Environment launched the 'National Inventory of Soil Erosion (INES) 2002-2012' to study the process of soil erosion in Spain. The aim of the current article is to assess the usefulness of this National Inventory as an instrument of control, measurement and monitoring of soil erosion in Spain. The methodology and main features of this National Inventory are described in detail. The results achieved as of the end of May 2010 are presented, together with an explanation of the utility of the Inventory as a tool for planning forest hydrologic restoration, soil protection, erosion control, and protection against desertification. Finally, the authors make a comparative analysis of similar initiatives for assessing soil erosion in other countries at the national and European levels. Copyright © 2011 Elsevier B.V.

    Full Text Available By comparison with the historiography of other European and Anglo-Saxon countries, the study of the origins and spread of Eugenics in Spain has not received much attention. Even less research has been done on the degree of acceptance of eugenic thought in the pedagogical domain or on the role teachers may have in the diffusion of eugenics. This paper attempts to explore the subject while focusing the analysis on the relations that were established among Medicine, Pedagogy and Eugenics in Spain during the first third of the 20th century. We will take as a point of reference and guiding line of thought the figure of the Asturian teacher Luis Huerta Naves, who was the driving force and tireless advocate of the eugenics movement in our country.

    Over the past 25 years, the incidence of newborns with congenital defects in Spain has fallen by 56.7% primarily due to the practice of "fetal risk" abortion, after prenatal diagnosis. In some cases, such as people with Down syndrome, the strategy involves the removal of 80-90% of those affected in pregnancy. After presenting the techniques used today and statistical data, we will make a reflection about the ethical justification for prenatal diagnosis programs and practice of "eugenic" abortion.

  11. Intercultural Education in Spain and Switzerland: a Comparative Approach

    Directory of Open Access Journals (Sweden)

    Ferran Ferrer

    2001-09-01

    Full Text Available Intercultural education during the last two decades in Spain and Switzerland can be understood as balancing acts because policymakers in both countries saw their school systems enrolling a growing number of immigrant and minority students. While solutions were formulated and adopted in response to each country's unique problems and political tradition, they were also driven by forces that fostered a restrictive immigration policy toward immigrants from third world countries. This article examines the emergence of intercultural education and compares diverse practices linked to this process. Some similarities were found in both socio-cultural contexts. The use of compensatory education with culturally diverse children contributes to school segregation. Although cultural and linguistic diversity is a structural and historical component of Spanish and Swiss identities, there is a clear separation between "internal" and "external" diversity in educational policy. It is interesting, for instance, to observe that the concept used in addressing regional identities in Spain and Switzerland is "bilingual education" while the theme used for immigrants is "intercultural education". We also identified some important differences between the two contexts. The number of immigrant youth is much more important in Switzerland. On the other hand, the presence of Gypsy students is a central issue of cultural diversity in Spain. The paper also reports on the general lack of teacher education departments to prepare their pre-service students for diverse schools. Most teacher education programs acknowledge in principle the importance of pluralistic preparation of teachers. In practice, however, most teacher education programs actually represent a monocultural approach. Continuing education in the field of intercultural education is linked to individual initiatives rather than to an institutional awareness of the importance of cross-cultural training. In order to

    In Spain, the absolute fatality figures decreased almost 50 percent between 1998 and 2009. Despite this great effort, road mortality is still of great concern to political authorities. Further progress requires efficient road safety policy based on an optimal set of measures and targets that consider the initial conditions and characteristics in each region. This study attempts to analyze road accidents in Spain and its provinces in time and space during 1998-2009. First, we analyzed daily, monthly, and nationwide (NUTS 0) development of road accidents, the correlation between logarithmic transformations of road accidents and territorial and socioeconomic variables, the causality by simple linear regression of road accidents and territorial and socioeconomic variables, and preliminary frequency by fast Fourier transform. Then we analyzed the annual trend in accidents in the Spanish provinces (NUTS 3) and found a correlation between the logarithmic transformations of the mortality rate, fatalities per fatal accident, and accidents resulting in injuries per inhabitant variables and population, population density, gross domestic product (GDP), length of road network, and area. Finally, causality was analyzed by simple linear regression. The most outstanding results were the negative correlation between mortality rate and population density in Spanish provinces, which has increased over time, and that road accidents in Spain have an approximate periodicity of 57 days. The fast Fourier transform analysis of road accident frequency in Spain was useful in identifying the periodic, harmonic components of accidents and casualties. The periodicity observed both for the period 1998-2009 and by year showed that the highest intensity in road accidents was bimonthly, despite the lower number of accidents and casualties in the spectra of amplitude and power and efforts to reduce the intensity and concentration during off-season travel (summer and December).

    In this cross-sectional study, we explored course content related to pharmacology and/or healthcare products and supplies in all nursing degree programs in Spain. Changes in nurse-prescribing legislation in Spain require that nurses take a certification course before prescribing over-the-counter products and medications. Using a cross-sectional descriptive study, between July and September 2014, the degree programs of all centers that offer a degree in nursing in Spain were examined, selecting those with course information available online. All centers offered at least one pharmacology course. One-third of the required courses had content related to pharmacology and healthcare products/supplies. The analysis showed that the course content and training received during the current nursing degree program provides the knowledge and skills needed to prescribe healthcare products/supplies and medications that do not now require a doctor's prescription, without the need for additional training and certification. It is essential that government regulation of nursing education be aligned with nursing competencies, curriculum standards, clinical practice, and evidence-based research to provide the maximum level of confidence for nursing professionals and their patients. © 2017 John Wiley & Sons Australia, Ltd.

    trans fatty acids are associated to several health disorders, as ischemic heart disease or diabetes mellitus. to assess the content of trans fatty acids in products in Spain, and the percentage of trans fatty acids respecting total fatty acids. 443 food products were acquired in Spain, and they were classified into groups. The content in fatty acids was analyzed using gas chromatography. Estimates of central tendency and variability of the content of trans fatty acids in each food group were computed (in g of trans fatty acids/100 g of product). The percentage of trans fatty acids respecting total fatty acids was calculated in each group. 443 products were grouped into 42 groups. Median of trans fatty acids was less than 0.55 g / 100 g of product in all groups except one. 83 % of groups had less than 2 % of trans fatty acids, and 71 % of groups had less than 1 %. the content of trans fatty acids in Spain is low, and it currently doesn't play a public health problem.

    In recent years, many public bike rental systems have proliferated in Spain. Unfortunately, many have had to close because of their poor financial feasibility. The aim of this paper is twofold. On the one hand, a benchmarking of the main public bicycle systems in Spain is conducted, analysing the growth in the last decades, with special emphasis on successful systems and on the recently failed. In addition, the financial feasibility of some successful systems in Spain is analysed: Seville, Valencia and Barcelona. Thus, major factors directly related to the viability of such systems are discussed. A proper and correct knowledge of these factors is essential when making decisions in mobility policies. The main factors on which the management company may decide are: pricing policy (annual and weekly rate), advertising rates, and system dimensions (number of docking stations, anchors and bicycles). There are other external factors not directly controlled by the company (subscribers, occupancy rate of advertising space and system maintenance cost) but which are crucial to their feasibility. To achieve the aforementioned objectives, mobility studies in Seville (1400 surveys) and Barcelona (1000 surveys) were conducted in order to achieve more accurate parameter values (time cycling, distances, used rate, frequencies, etc.). Despite the similarities between the systems in Valencia and Seville, they have shown very different profitability. The high profitability in Valencia and Barcelona is highlighted in contrast to the case of the Seville system. (Author)

    Full Text Available Men and women wage differences is a widely discuss topic in the literature. Some authors point the fact that size of gender wage gap (GPG is not the same across wage distribution. GPG ratio is accelerating at the top of it. Thus, the main goal of presented study is to analyse impact of outliers (top earners on the values of GPG ratio and results of its decomposition. In addition we compare outcomes obtained for Spain and Poland. Elimination outliers from the sample will reduce values of men and women wage gap ratios not only in unadjusted form but in adjusted form as well. Study is based upon the Eurostat’s Structure of Earnings Survey (SES individual data in respect of 2014. In the paper we discuss results of Oaxaca-Blinder decomposition (in extension proposed by Oaxaca and Ransom obtained for Spain and Poland. Obtained results indicated two points above all. Firstly, although unadjusted GPG ratios for Spain and Poland differ significantly, the adjusted GPG ratios are at the same level (about 15%. Such situation shows the real men and women wage differences are at the same level in both countries. This is an additional indication that women situation on Polish labour market in similar to the Spanish one. Secondly, after elimination of outliers the values of GPG measures (in adjusted and unadjusted form decreased, as was expected. These falls came to approximately 3 p.p. It can be considered as significant change.

  10. Ecological compensation and Environmental Impact Assessment in Spain

    Villarroya, Ana; Puig, Jordi

    2010-01-01

    To achieve meaningful sustainable development, Environmental Impact Assessment (EIA) should avoid the net losses in the environment resource base. But EIA practice does not always avoid the losses caused by the implementation of the projects under EIA regulation. Some environmental impacts are, simply, admitted, even without enforcing any form of compensation. When applied, compensation is sometimes just a monetary payment to offset the environmental loss. This paper looks for evidence on the role that compensation is given at present in EIA practice in Spain, and for some of its conceptual and regulatory roots. Specifically, it explores how compensation is addressed in 1302 records of decision (RODs) on those projects subject to the Spanish EIA regulation published during the years 2006 and 2007, to know how far Spain is from preserving the environmental resource base managed through this particular aspect of EIA practice. As a result, it is concluded that the practice of ecological compensation in EIA in Spain is much lower than it could be expected in a theoretical sustainability context committed to avoid net losses in the environment resource base, mainly due to an EIA practice focused on on-site mitigation that allows these net losses.

    Obesity is a major cardiovascular risk factor. In Spain, few studies have physically measured height and weight to estimate the magnitude of the problem. The aim of this study was to determine the prevalence of child and adolescent obesity in Spain in 2012. We performed a cross-sectional probability sample of 1018 children, representative of the Spanish population aged between 8 and 17 years old, with objectively measured height and weight, along with other sociodemographic variables. We calculated the prevalence of overweight and obesity according to the criteria of the World Health Organization, the International Obesity Task Force, and the enKid study. In the group aged 8 to 17 years old, the prevalence of overweight and obesity was 26% and 12.6%, respectively; 4 in 10 young people were overweight or obese. Excess weight was found in 45% of the group aged 8 to 13 years and in 25.5% of that aged 14 to 17 years. This cardiovascular risk factor was associated with lower social class and lower educational level. The prevalence of overweight and obesity in children and adolescents in Spain remains high (close to 40%), but has not increased in the last 12 years.

    Full Text Available The Spanish climate is full of contrasts, with torrential rains and long droughts; under these conditions, appropriate water management is essential. In Spain, until the end of the twentieth century, water management and legislative development lagged behind other more developed countries. Nowadays, great efforts are being made to reverse this situation and improve both water management and legislation in order to control the two main problems related to stormwater management in cities: floods and diffuse pollution. In this context, Sustainable Urban Drainage Systems (SUDS were developed as the main solution to these problems. The study of these techniques started in the 1970s in the USA, but they were not studied in Spain until 1993 when the University of Cantabria and CLABSA started to look into solutions for stormwater management. After 20 years of research and application, sustainable drainage in Spain is still behind other countries in spite of the efforts to change this situation, notably by the University of Cantabria with 10 years of experience in these techniques, mainly regarding pervious pavements, where more than 13 related research projects have been carried out. The future challenges focus on the application of pervious pavements for Urban Hydrological Rehabilitation.

É relatado um caso de distrofia granular em paciente de 38 anos do sexo masculino. Foi realizado exame oftalmológico completo e OCT para documentação do caso. O aparelho utilizado foi o Stratus OCT III, originalmente desenvolvido para avaliação do segmento posterior. A acuidade visual corrigida foi de 20/50 em ambos os olhos. À biomicroscopia, foram observadas opacidades em "floco de neve" em diferentes níveis do estroma corneano bilateral e de forma simétrica. A avaliação pelo OCT revelou múltiplos pontos hiperreflectivos nas camadas superficiais e profundas do estroma. Foi possível acessar a anatomia morfológica da córnea através de cortes seriados realizados pelo Stratus OCT III e confirmar a profundidade dos depósitos corneanos.The purpose of this case report is to correlate clinical features of granular dystrophy using 820 nm optical coherence tomography (OCT in order to determine the depth of intrastromal corneal deposits. We report a case of a 38-year-old man with granular dystrophy. After complete ophthalmologic examination the patient was submitted to OCT, using the Stratus OCT III, originally proposed for studying disorders of the posterior segment. Best-corrected visual acuity was 20/50 in both eyes. Biomicroscopy revealed bilateral "snowflake"opacities in different levels of the stromal layer. OCT disclosed multiple hiperreflective dots in anterior and deeper stromal layers. It was possible to assess the morphology of the cornea and to determine the depth of the corneal deposits with serial cross-sectional OCT scans using the Stratus OCT III.

Nesta perspectiva, apresenta uma articulação entre a história da óptica e as principais características da filosofia histórica de Gaston Bachelard, dando ênfase: aos períodos de rupturas e descontinuidades presentes no constante confronto entre o modelo corpuscular e ondulatório da luz; à permanente retificação do erro - e ao novo conceito de verdade presente na construção da concepção sobre a natureza da luz -; à noção de recorrência histórica articulada à análise dos estudos sobre reflexão e refração; ao uso do recurso analógico na estruturação da hipótese ondulatória da luz, proposta por Huygens; e à dialética racionalismo-empirismo no exemplo da natureza dual dos elétrons.The present article explores the interaction between History and the Philosophy of Science. In this way, it presents an articulation between the History of Optics and the main characteristics of Gaston Bachelard´s historical philosophy. It emphasizes: firstly, the periods of rupture and discontinuities present in the confrontation between the light corpuscular and wave models; secondly, the permanent error rectification, in the sense that one knowledge abuts another, and the new concept of truth, present in the construction of the conception about the nature of light; thirdly, the notion of historical recurrence, articulated in the analysis of studies about reflection and refraction particularly Arquimedes' polemic of incandescent mirrors; fourthly, the use of analogical reasoning in the structuring of the light wave hypothesis proposed by Huygens; and finally, the rationalismempiricism dialectics in the example of the dual nature of the electron.

Para tal, foram determinados a capacidade emulsionante (EC, o índice de atividade emulsionante (EAI e a estabilidade da emulsão (ES. O efeito da ação da tripsina sobre estas propriedades foi, também, verificado, tendo sido preparados cinco hidrolisados enzimáticos. Os resultados obtidos indicam que a hidrofobicidade e o EAI apresentaram um máximo em pH 3,0 e 7,0, respectivamente, enquanto que as outras propriedades praticamente não foram influenciadas pela variação de pH. A hidrólise tríptica provocou uma redução da solubilidade e da EC, não afetou o EAI e a ES, tendo contribuído para melhorar apenas a hidrofobicidade, em alguns tempos de reação.Aiming to use of the bovine plasma as functional agent of foods, we studied its solubility, hidrophobicity and ability to form and to stabilize emulsions, in the range of pH from 3.0 to 8.0. Emulsifying capacity (EC, the emulsifying activity index (EAI and the stability of the emulsion (ES were determinated. The effect of the trypsin on these properties was also studied and five enzymatic hydrolysates were prepared. The results showed that hydrophobicity and EAI presented a maximum value at pH 3.0 and 7.0, respectively, while the other properties practically were not influenced by the pH variation. The tryptic hydrolysis produced a reduction of the solubility and EC, it showed no effect on EAI and ES and improved only the hidrophobicity in some periods of reaction.

    Full Text Available People with epilepsy have been discouraged from participating in physical activity due to the fear that it will exacerbate seizures. Clinical and animal studies indicate a reduction of seizure frequency as well as decrease susceptibility to subsequently evoked seizures after an exercise program. Analyses from experimental studies of animals with epilepsy submitted to physical training programs were performed. In all studies the physical training was able to reduce the number of spontaneous seizures in rats with epilepsy. Seizure occurrence during exercise was relatively absent in the majority of studies. No death was found in animals with epilepsy during 1680 h of exercise. Based on these results it is plausible encouraging persons with epilepsy to non-pharmacological treatments and preventative measures such as physical exercise.Pessoas com epilepsia têm sido desencorajadas da prática de atividade física por receio do exercício físico exacerbar as crises epilépticas. Estudos clínicos e em animais mostram uma redução da frequência de crises, assim como diminuição da susceptibilidade a crises subseqüentes após programa de exercício físico. Neste estudo realizamos uma análise de estudos experimentais de animais com epilepsia submetidos a programas de exercício físico. Em todos os estudos, o treinamento físico foi capaz de reduzir o número de crises espontâneas em ratos com epilepsia. A ocorrência de crises durante o exercício físico foi relativamente ausente na maioria dos estudos. Nenhuma morte foi encontrada em animais com epilepsia durante 1680 h de exercício físico. Baseados nestes resultados parece aceitável encorajar as pessoas com epilepsia a tratamentos não farmacológicos e medidas preventivas como o exercício físico.

    Full Text Available In this paper it was investigated the organoleptic properties and machining of six potential woods for bows of stringed instruments and compared the results with those mentioned for the Caesalpinia echinata wood, the reference for modern bows. Thirty wood stores were visited in different cities of the São Paulo state to verify the commercial availability of these woods. We concluded that despite the traditionalism of the red tones in the woods for bows, woods with yellowish tones such as Handroanthus spp. and Dipteryx spp. or brownish such as Diplotropis spp. with appropriate properties, may offer alternative colors and textures to the musicians. It was observed that the Mezilaurus itauba and Astronium lecointei, woods with easy machining, have no potential suitable for bows. Regarding to availability, all woods tested are relatively easy to find nowadays in the wood market. Handroanthus spp. and Dipteryx spp. showed greater potential for making bows for professional musicians.The woods of Mezilaurus itauba and Astronium lecointei did not show good potentialfor bows.Neste trabalho foram investigadas as propriedades organolépticas e a trabalhabilidade de seis madeiras potenciais para arcos de instrumentos de corda e os resultados comparados com os da madeira de Caesalpinia echinata, referência para arcos modernos. Foram visitadas 30 madeireiras em diferentes cidades do Estado de São Paulo para observar a disponibilidade das seis madeiras. Conclui-se que apesar do tradicionalismo dos tons de vermelhos na madeira para arcos, outras madeiras com tons amarelados como Handroanthus spp. e Dipteryx spp. ou acastanhados como Diplotropis spp., desde que possuam propriedades adequadas, podem oferecer alternativas de cores e texturas para os músicos. Madeiras de fácil trabalhabilidade, como Mezilaurus itauba e Astronium lecointei não são adequadas para a fabricação dos arcos. Atualmente, todas as madeiras testadas são relativamente fáceis de
