Sampling for sabethine mosquitoes occurred intermittently from September 2007 to April 2013 in 17 municipalities, located in 5 departments (divisions) in the northern Andean coffee-growing regions of Colombia. Of the 9 genera within the Sabethini tribe known to occur in the Neotropical region, 6 were encountered including 15 species: Jonhbelkinia ulopus, Limatus durhamii, Sabethes ignotus, Sa. luxodens, Sa. undosus, Shannoniana fluviatilis, Trichoprosopon compressum, Tr. digitatum, Tr. evansae, Tr. pallidiventer s.l., Tr. pallidiventer s.s., Wyeomyia arthrostigma, Wy. oblita, Wy. ulocoma, and Wy. undulata. The species Sa. luxodens and Wy. undulata constitute new records for Colombia. These records broaden the knowledge of this important group that includes some important species related to the arbovirus transmission. Records are from the northern Colombian Andes, a region noted for coffee cultivation and ecotourism.

Estudio de la resistencia a la abrasión de capas vitrocerámicas depositadas sobre acero

Full Text Available Wear test has been completed on two types of layered materials: a non-reinforced enamel plate and a ceramic reinforced enamel plate. The latter has been tested in two forms: with 10 wt. % and 20 wt. % ceramic particles reinforcement. For comparison the same test has also been completed on polished steel. Wear resistance was measure using a tribometer, equipped with a chromium steel sphere of 6 mm diameter. The sphere-plate surface contact area increases with distance covered, which in the polished steel provokes exponential increments in wear values. This exponential behaviour was not observed in the enamel plates due to their greater wear resistance. The reinforcement of the enamel plates with ceramic particles increases the wear resistance. A higher percentage of ceramic reinforcement results in a greater wear resistance of the plates.

Se han realizado ensayos de desgaste, tanto en placas esmaltadas sin refuerzo como en esmaltes con distinto porcentaje de carga cerámica (10 y 20% en peso, y se han comparado frente al del acero base pulido. Las medidas de resistencia a la abrasión se han obtenido utilizado un tribómetro con bola de acero al cromo de 6 mm de diámetro. El aumento de la superficie de contacto bola-placa a medida que aumenta la distancia recorrida, provoca aumentos exponenciales en los desgastes en el caso del acero pulido. Sin embargo, en el caso de las chapas esmaltadas no se observa este comportamiento, debido a la mayor resistencia al desgaste de las mismas. Cuando las capas esmaltadas están reforzadas con cargas cerámicas, la resistencia al desgaste aumenta con el porcentaje de refuerzo cerámico.

Systematized biweekly human bait collections were made three times a day, for periods of 2 or 3 h each, in sylvatic and rural areas for 24 consecutive months (January 1991 to December 1992. A total of 24,943 adult mosquitoes belonging to 57 species were collected during 622 collective periods. Aedes scapularis, Coquillettidia chrysonotum, Cq. venezuelensis, Wyeomyia dyari, Wy. longirostris, Wy. theobaldi and Wy. palmata were more frequently collected at swampy and at flooded areas. Anopheles mediopunctatus, Culex nigripalpus, Ae. serratus, Ae. fulvus, Psorophora ferox, Ps. albipes and the Sabethini in general, were captured almost exclusively in forested areas. An. cruzii, An. oswaldoi and An. fluminensis were captured more frequently in a residence area. However, Cx. quinquefasciatus was the only one truly eusynanthropic. An. cruzii and Ae. scapularis were captured feeding on blood inside and around the residence, indicating that both species, malaria and arbovirus vectors respectively, may be involved in the transmission of these such diseases in rural areas.

Full Text Available The sol-gel process is widely used to obtain coatings on glass-ceramic substrates in order to improve the scratch and abrasion resistance, also providing a bright and homogeneous appearance of a glaze avoiding expensive final polishing treatments. This paper describes the preparation of silica and silica / zirconia coatings by sol-gel method on Li2O-Al2O3-SiO2 (LAS glassceramic substrates produced by sintering. The coatings were deposited by dip-coating on LAS substrates and characterized by optical microscopy and spectral ellipsometry. On the other hand, hardness and elastic modulus, coefficient of friction and abrasion and scratch resistance of the coatings were determined and compared with the substrate properties. Coatings deposited on LAS glass-ceramic confere the substrate a bright and homogeneous aspect, similar to a glaze, improving the appearance and avoiding the final polishing. However these coatings do not increase the scratch resistance of the substrate only equaling the properties of the glass-ceramic.El proceso sol-gel es un método interesante para la producción de recubrimientos vítreos sobre sustratos vitrocerámicos con el fin de mejorar su resistencia al rayado y al desgaste, y proporcionando además un aspecto homogéneo, vidriado y brillante que evite los costosos tratamientos finales de pulido. Este trabajo describe la preparación de recubrimientos de sílice y sílice/ circona por el método sol-gel sobre sustratos vitrocerámicos del sistema Li2O-Al2O3-SiO2 (LAS producidos por sinterización.

Full Text Available The mineralogical results of the Bolonia Unit are analysed in the work. The Cabrito-l section is characterized by the mineralogical association kaolinite-illite-interestratified I-S, and is similar to the section of Punta Tarifa series of the Algeciras Unit. The Pulido section, characterized by the mineralogical association (kaolinite-illite-chlorite, may be considered as the most distal zone of the «areniscoso-micaceo» flysch of the Algeciras Unit. The most significant difference between the fine fractions of these Units is the remarkable development, in the Bolonia Unit, of authigenic chlorites, whose composition shows a diagenetic environment rich in Fe and Mg. On the other hand, the mineralogical composition of the fine fraction has made possible the identification in the Bolonia Unit, not only the «areniscas del Aljibe» levels, but also clay levels of Aljibe Unit, which has not been noticed until now. These mineralogical and lithological aspects lead to consider the Bolonia Unit as an intermediate Unit between the Algeciras and the Aljibe ones.En este trabajo se recogen los resultados obtenidos a partir del estudio mineralógico de la Unidad de Bolonia. De los perfiles estudiados, el del Cabrito, caracterizado por la asociación mineralógica caolinita-ilita, interestratificados I-E, es similar en gran medida a la serie tipo punta Tarifa de la Unidad de Algeciras. El perfil del Pulido, caracterizado por la asociación (caolinita-ilita-clorita puede interpretarse como la parte más distal del flysch areniscoso-micáceo de la Unidad de Algeciras. La diferencia más notable en la mineralogía de la fracción fina entre ambas Unidades se refiere al desarrollo notable, en Bolonia, de cloritas autigénicas, cuya composición indica un medio diagenético rico en Fe y Mg.

Clinical teaching at Lisbon's Faculty of Medicine is analyzed in its two phases: 1. A period of stability and continuity of the institution (from 1911 to 1947) characterized by good rules in the selection of teachers: an impressive group of personalities (F. Gentil, Pulido Valente, Reynaldo dos Santos, Egas Moniz, A. Flores, Sobral Cid, Lopo de Carvalho, Gama Pinto, etc). At the some period a true University Hospital (of Santa Marta) provided clinical investigation (cerebral angiography and leucotomy, aortography and arteriography of the limbs, angiopneumography, endarterectomy) and the creation of new specialties (neurosurgery, vascular surgery, pneumology). 2. A period of instability due to a deleterious political intervention (from 1947 to the present day) responsible for the destruction of the structure and concept of a new teaching hospital (Hospital de Santa Maria). As a result of the socio-political situation conflicting law and vicious rules lead to an excess of non-selected teachers and an alarming increase of students, patients and medical doctors. A change from the present situation and a new concept of clinical teaching must be imagined.

Methods and tools to simulate the effect of economic instruments in complex water resources systems. Application to the Jucar river basin.

The main challenge of the BLUEPRINT to safeguard Europe's water resources (EC, 2012) is to guarantee that enough good quality water is available for people's needs, the economy and the environment. In this sense, economic policy instruments such as water pricing policies and water markets can be applied to enhance efficient use of water. This paper presents a method based on hydro-economic tools to assess the effect of economic instruments on water resource systems. Hydro-economic models allow integrated analysis of water supply, demand and infrastructure operation at the river basin scale, by simultaneously combining engineering, hydrologic and economic aspects of water resources management. The method made use of the simulation and optimization hydroeconomic tools SIMGAMS and OPTIGAMS. The simulation tool SIMGAMS allocates water resources among the users according to priorities and operating rules, and evaluate economic scarcity costs of the system by using economic demand functions. The model's objective function is designed so that the system aims to meet the operational targets (ranked according to priorities) at each month while following the system operating rules. The optimization tool OPTIGAMS allocates water resources based on an economic efficiency criterion: maximize net benefits, or alternatively, minimizing the total water scarcity and operating cost of water use. SIMGAS allows to simulate incentive water pricing policies based on marginal resource opportunity costs (MROC; Pulido-Velazquez et al., 2013). Storage-dependent step pricing functions are derived from the time series of MROC values at a certain reservoir in the system. These water pricing policies are defined based on water availability in the system (scarcity pricing), so that when water storage is high, the MROC is low, while low storage (drought periods) will be associated to high MROC and therefore, high prices. We also illustrate the use of OPTIGAMS to simulate the effect of ideal water

We describe the design and performance of a new source of polarized spins that can be employed in experiments that search for macroscopic interactions between particles with intrinsic spin. In this article we concentrate on the analysis of the performance of the spin source in generating putative scalar-pseudoscalar forces. We outline two methods of calculating the magnitude of such forces and compare the predictions of the models. We discuss the manufacture of the spin source and the measurements that we have carried out in order to place upper limits on systematic effects that would limit the sensitivity of such searches. We have shown, in a recent article to Physical Review Letters [G. D. Hammond, C. C. Speake, C. Trenkel, and A. Pulido-Paton, Phys. Rev. Lett. 98, 081101 (2007)], that the combination of the spin source together with the torque sensitivity of our torsion balance improves constraints on the coupling strength of macroscopic scalar-pseudoscalar interactions by 10 orders of magnitude at a range of 1 mm. This paper further supports that work and provides a detailed description and characterization of the spin source

Clinical teaching at Lisbon's Faculty of Medicine is analyzed in its two phases: 1. A period of stability and continuity of the institution (from 1911 to 1947) characterized by good rules in the selection of teachers: an impressive group of personalities (F. Gentil, Pulido Valente, Reynaldo dos Santos, Egas Moniz, A. Flores, Sobral Cid, Lopo de Carvalho, Gama Pinto, etc). At the same period a true University Hospital (of Santa Marta) provided clinical investigation (cerebral angiography and leucotomy, aortography and arteriography of the limbs, angiopneumography, endarterectomy) and the creation of new specialities (neurosurgery, vascular surgery, pneumology) (Act. Méd. Port. 1990; 2: 109-114). 2. A period of instability due to a deleterious political intervention (from 1947 to the present day) responsible for the destruction of the structure and concept of a new teaching hospital (Hospital de Santa Maria). As a result of the socio-political situation conflicting laws and vicious rules lead to an excess of non-selected teachers and an alarming increase of students, patients and medical doctors A change from the present situation and a new concept of clinical teaching must be imagined.

Full Text Available Two types of ornamental stones, namely granite (Blanco Rafaela or Zarzalejo Granite and microcrystalline limestone (marble known commercially as Gris Pulpis, treated for different surface finishes, were tested for suitability as paving slabs. The finishes tested in both stones were polishing, hammering, honing and flaming, while acid treatment and abrasion were applied to limestone only and sawn finishes were only studied in granite.The stones were tested for the three physical properties that determine suitability for use as paving slabs; flexural strength under a concentrated load, and abrasion and slip resistance. Laboratory freeze-thaw cycle ageing tests were also conducted and flexural strength subsequently evaluated. Stone water sorption proved to be substantially unaltered by the type of finish employed. Finish barely affected flexural strength, except in the case of limestone flaming, where it was lower. Hammering was found to provide good slip resistance in both stones. The best slip performance for granite, however, was found for flamed specimens. Finish was shown to have no effect on abrasion resistance in either of the stone materials. Polished limestone suffered the least damage in freeze-thaw cycles, whereas freeze-thaw resistance was similar in all the granite specimens, regardless of the finish used.Se han estudiado, para su utilización como baldosas de pavimentos, granito (Blanco Rafaela o Granito de Zarzalejo y caliza microcristalina (mármol comercial Gris Pulpis con diferentes acabados. Estos acabados son: pulido, apomazado, abujardado y flameado en ambas rocas y además acabado al ácido y amolado en la caliza. Se han determinado mediante ensayos estandarizados las tres propiedades físicas de mayor interés para el uso de la piedra natural como baldosa en pavimentos de exteriores: resistencia a la flexión bajo carga concentrada, a la abrasión y al deslizamiento.

A Contribution for the Automatic Sleep Classification Based on the Itakura-Saito Spectral Distance

Cardoso, Eduardo; Batista, Arnaldo; Rodrigues, Rui; Ortigueira, Manuel; Bárbara, Cristina; Martinho, Cristina; Rato, Raul

Sleep staging is a crucial step before the scoring the sleep apnoea, in subjects that are tested for this condition. These patients undergo a whole night polysomnography recording that includes EEG, EOG, ECG, EMG and respiratory signals. Sleep staging refers to the quantification of its depth. Despite the commercial sleep software being able to stage the sleep, there is a general lack of confidence amongst health practitioners of these machine results. Generally the sleep scoring is done over the visual inspection of the overnight patient EEG recording, which takes the attention of an expert medical practitioner over a couple of hours. This contributes to a waiting list of two years for patients of the Portuguese Health Service. In this work we have used a spectral comparison method called Itakura distance to be able to make a distinction between sleepy and awake epochs in a night EEG recording, therefore automatically doing the staging. We have used the data from 20 patients of Hospital Pulido Valente, which had been previously visually expert scored. Our technique results were promising, in a way that Itakura distance can, by itself, distinguish with a good degree of certainty the N2, N3 and awake states. Pre-processing stages for artefact reduction and baseline removal using Wavelets were applied.

Full Text Available Some physical properties of three ornamental granites with different superficial finishes (polished, sawn and flamed were quantified by standard tests. These granites are commercially known as Rosa Porrino, Rosavel and Blanco Alcazar. The determined properties were: density, open porosity, water absorption, capillarity, evaporation, vapour absorption and water vapour permeability. The values of the hydric properties in the studied granites fundamentally depended on their textural characteristics, mainly grain size, micro cracking network and open porosity, and, to a lesser extent, on their superficial finish.

El estudio analiza las diferencias en el comportamiento hídrico de tres granitos con diferentes acabados superficiales: pulido, corte de sierra y chorro de fuego. Estos granitos se comercializan con los nombres de Rosa Porrino, Rosavel y Blanco Alcázar. Las propiedades determinadas han sido: densidad, porosidad abierta, absorción libre de agua, absorción de vapor de agua, absorción de agua por capilaridad, evaporación y permeabilidad al vapor de agua. Los valores de las propiedades hídricas determinadas dependen fundamentalmente de las características texturales: tamaño de grano, microfisuras y porosidad abierta y, en menor medida, de los acabados superficiales.

Immatures of both Aedes aegypti and Aedes albopictus have been found in water-holding bromeliad axils in Brazil. Removal of these plants or their treatment with insecticides in public and private gardens have been undertaken during dengue outbreaks in Brazil despite uncertainty as to their importance as productive habitats for dengue vectors. From March 2005-February 2006, we sampled 120 randomly selected bromeliads belonging to 10 species in a public garden less than 200 m from houses in a dengue-endemic neighborhood in Rio de Janeiro. A total of 2,816 mosquito larvae and pupae was collected, with an average of 5.87 immatures per plant per collection. Culex (Microculex) pleuristriatus and Culex spp of the Ocellatus Group were the most abundant culicid species, found in all species of bromeliads; next in relative abundance were species of the genus Wyeomyia. Only two individuals of Ae. aegypti (0.07%) and five of Ae. albopictus (0.18%) were collected from bromeliads. By contrast, immatures of Ae. aegypti were found in manmade containers in nearly 5% of nearby houses. These results demonstrate that bromeliads are not important producers of Ae. aegypti and Ae. albopictus and, hence, should not be a focus for dengue control. However, the results of this study of only one year in a single area may not represent outcomes in other urban localities where bromeliads, Ae. aegypti and dengue coincide in more disturbed habitats.

The Caatinga is the least known Brazilian biome in terms of the diversity of Culicidae. No systematic study of the diversity or ecology of the mosquitoes of this biome is available, despite the importance of vector diseases in Brazil. The present study addressed the mosquito biodiversity in the Caatinga biome by sampling adult populations. Specimens were sampled monthly from March 2013 to September 2014 in a Caatinga conservation unit located in the Brazilian semiarid zone. Mosquito collections were carried out in Shannon traps from late afternoon to early evening, and manual aspiration was used to capture diurnal species as well. A total of 4,692 mosquitoes were collected. The most dominant and constant species were all undescribed species belonging to the genera Wyeomyia and Runchomyia, which together represented 80% of the specimens. The most abundant species of epidemiological importance was Haemagogus (Con.) leucocelaenus. The abundance of mosquitoes was positively associated with the relative humidity and temperature recorded during the month preceding the collection date. In the Caatinga, the diversity of adult mosquitoes was associated with the availability (quantity and diversity) of natural larval habitats found in the different phytophysiognomies of the biome, which vary according to temperature and humidity. The number of species unknown to science reflects the levels of endemism that exist in the study area, and reinforces the need to further taxonomic investigation in the biome.

Full Text Available Previous studies have found quantity of exposure, i.e., frequency of exposure (Horst et al., 1998; Webb, 2008; Pellicer-Sánchez and Schmitt, 2010, is important for second language (L2 contextual word learning. Besides this factor, context constraint and L2 proficiency level have also been found to affect contextual word learning (Pulido, 2003; Tekmen and Daloglu, 2006; Elgort et al., 2015; Ma et al., 2015. In the present study, we adopted the event-related potential (ERP technique and chose high constraint sentences as reading materials to further explore the effects of quantity of exposure and proficiency on L2 contextual word learning. Participants were Chinese learners of English with different English proficiency levels. For each novel word, there were four high constraint sentences with the critical word at the end of the sentence. Learners read sentences and made semantic relatedness judgment afterwards, with ERPs recorded. Results showed that in the high constraint condition where each pseudoword was embedded in four sentences with consistent meaning, N400 amplitude upon this pseudoword decreased significantly as learners read the first two sentences. High proficiency learners responded faster in the semantic relatedness judgment task. These results suggest that in high quality sentence contexts, L2 learners could rapidly acquire word meaning without multiple exposures, and L2 proficiency facilitated this learning process.

Species Composition and Ecological Aspects of Immature Mosquitoes (Diptera: Culicidae in Bromeliads in Urban Parks in the City of São Paulo, Brazil

Walter Ceretti-Junior

2015-10-01

Full Text Available Background: Bromeliads can be epiphytic, terrestrial or saxicolous and use strategies to allow water to be re­tained in their leaf axils, where various arthropods can be found. These include mosquitoes, whose larvae are the most abundant and commonly found organisms in the leaf axils. The objective of this study was to look for im­mature forms of mosquitoes (the larval and pupal stages in bromeliads in municipal parks in São Paulo and to discuss the ecological and epidemiological importance of these insects.Methods: From October 2010 to July 2013, immature mosquitoes were collected from bromeliads in 65 munici­pal parks in the city of São Paulo, Brazil, using suction samplers. The immature forms were maintained until adult forms emerged, and these were then identified morphologically.Results: Two thousand forty-two immature-stage specimens belonging to the genera Aedes, Culex, Trichoprosopon, Toxorhynchites, Limatus and Wyeomyia were found in bromeliads in 15 of the 65 parks visited. Aedes albopictus was the most abundant species (660 specimens collected, followed by Culex quinquefasciatus (548 specimens and Cx. (Microculex imitator (444. The taxa with the most widespread distribution were Ae. aegypti and Toxorhynchites spp, followed by Ae. albopictus and Cx. quinquefasciatus.Conclusion: Bromeliads in urban parks are refuges for populations of native species of Culicidae and breeding sites for exotic species that are generally of epidemiological interest. Hence, administrators and surveillance and mosquito-control agencies must constantly monitor these microenvironments as the presence of these species endangers the health of park users and employees as well as people living near the parks.

Full Text Available Si bien las proteínas de origen animal en muchas instancias pueden tener mejores características funcionales que las proteínas de origen vegetal, el incremento de su costo puede favorecer al uso expansivo de las fitoproteínas como reemplazo. Una de las fuentes de proteínas de origen vegetal es el salvado de arroz, que se obtiene como subproducto en el proceso de pulido del arroz integral (Oryza santiva L para producir el arroz blanco. Se estudió los procesos de cremado, floculación y coalescencia de emulsiones preparadas con proteínas del salvado de arroz a pH 6,0 y 8,0. La obtención de las proteínas del salvado de arroz se realizó en un medio alcalino, partiendo de salvado de arroz desengrasado. El proceso de desestabilización de las emulsiones se analizó a partir de los datos obtenidos por el método de retrodispersión de luz mediante un equipo Turbiscan 2000; en el caso del cremado los datos fueron ajustados a una cinética bifásica con una componente de segundo orden (hiperbólica y otra con un comportamiento sigmoidal. Las emulsiones preparadas a pH 8 presentaron una mayor estabilidad frente al cremado, mientras que los procesos de floculación y coalescencia no fueron influenciados por los distintos valores de pH.

Entomological studies conducted in large hydroelectric infrastructure projects are a tool for the prevention and control of vector-borne diseases. These diseases emerge as a consequence of changes made to the terrain that often increase the natural and artificial mosquito larval habitats. Many of these insects are of public health importance and population increases result in an increased risk of disease transmission. The culicine (mosquito) and phlebotomine (sand fly) populations were characterized in the area of the Porce II and Porce III hydroelectric projects of Antioquia between 1990 to 2009. Periodical entomological samplings were made in the area of impact, in the workers camps, and construction sites. Adult specimens were captured with nets, Shannon light traps, CDC light traps, and protected human bait. Mosquito larvae of the following species were identified: Culex coronator, Culex nigripalpus, Culex corniger, Culex quinquefasciatus and Limatus durhami. The most frequently identifiers of larval habitats were low tanks, waste cans, tires, and aquatic plants. Aedes aegypti specimens were captured in only two rural locations from two municipalities within the area of influence. Specimens from the following mosquito genera were captured in forest areas: Aedes, Mansonia, Culex, Psorophora, Wyeomyia, Phonyomyia, Uranotaenia, Haemagogus and Sabethes. The most important mosquito found was Haemogogus janthinomis, an efficient yellow fever vector in Colombia. The area has been endemic for leishmaniasis and in the current study, 20 species of Lutzomyia sand flies, potential vectors, were identified. Among malaria vectors, the most important species found in the area were Anopheles nuneztovari and Anopheles pseudopunctipennis. A wide variety of vectors were discovered in the area of the Porce II and Porce III hydroelectric projects, and many of these were relevant for public health. Further monitoring will be necessary to minimize disease transmission risks among the

Full Text Available Background: An outbreak of Legionella pneumophila serogroup 1, with 403 cases was identified on the 7th November 2014 in Vila Franca de Xira, Portugal. Outbreak source was the wet cooling system of a local factory. Hospital Pulido Valente was one of the hospitals receiving patients with Legionnaires’ disease (LD. Methods: We describe the clinical findings and diagnostic methods used among the 43 confirmed or probable cases admitted to our department. Results: 60.5% were male, mean age was 56.1 ± 13.5 years and tobacco smoking was the most frequent risk factor (76.7%. All patients had fever, 62.8% ≥39.5 °C, 72.1% had chills and myalgia/arthralgia and 62.8% had dry cough. Extra pulmonary symptoms were frequent: confusion and headache occurred in 34.9% and gastrointestinal symptoms in 20.9%.High C-Reactive Protein (55.8% ≥30 mg/dL and hyponatremia (62.8% were the laboratorial abnormalities most commonly found. Hypoxemia occurred in 55.8% and hypocapnia in 93%. Urinary Antigen Test (UAT was positive in 83.7% of the cases. Conclusions: Although not specific, a combination of risk factors, symptoms and laboratory findings can be highly suggestive of LD, even in an outbreak. This should prompt diagnosis confirmation. Routine use of UAT in less severe cases of community acquired pneumonia might contribute to earlier diagnosis. Keywords: Legionnaires’ disease, Outbreak, Clinical presentation

Mejora de las características de los sensores magnéticos de piezoeléctrico y material ferromagnético

Prieto, J. L.

1999-12-01

Full Text Available In this work we describe a new fabrication method for magnetostrictive-piezoelectric sensors that improve several characteristics. The mechanical coupling between the ferromagnetic and the piezoelectric has been optimised by means of a mixed method: electrolytic deposition of a copper layer, playing the role of polished interface, and sputtering deposition of a highly magnetostrictive material on the interface. This method allows to remove the viscous fluid, improving the sensitivity, time stability and opening the possibility to industrial fabrication. The fabrication method opens also the possibility of miniaturisation or even integration of the sensor.

En este trabajo se describen varias mejoras al método de fabricación de sensores magnéticos de piezoeléctrico y material ferromagnético. Se ha mejorado el acoplo mecánico entre los dos materiales con un método combinado: deposición electrolítica de una capa de cobre que actuar. de adaptador para eliminar la rugosidad superficial del piezoeléctrico; pulido mecánico y electrolítico de la superficie de cobre y, por último, una deposición posterior de material ferromagnético de alta magnetostricción por Sputtering. Con este método se elimina el pegamento viscoso que une los dos materiales y por tanto, se mejora considerablemente el acoplo mecánico y con él la sensibilidad del sensor, la estabilidad con el tiempo y la repetibilidad en el proceso de fabricación. Se abre así una puerta a una futura integración de estos sensores y a una posible fabricación en serie.

Full Text Available For 9 months we evaluated a portable device to transfer patient-clinician data by Internet: oximetry, ECG, clinical questionnaires and messages from the doctor. Fifty-one patients with severe chronic respiratory insufficiency (CRI were followed at the hospital Pulido Valente and Espirito Santo and 21 asthmatics (A were followed at the latter hospital. The use and acceptance of this device was evaluated through questionnaires soliciting patients’ and health professionals’ opinions. Patients with CRI followed in Lisbon were also asked about hospital admissions and quality of life compared with a nine month period before the monitoring programme.CRI patients found learning to use the system more difficult; the majority (80% reported problems with the equipment, qualified as rare/occasional in 62% of the cases. For 31 CRI patients followed in Lisbon, the use of the system was classified as correct in 12 patients, incorrect in 7 and reasonable in 12 patients. The first group had a reducded number and duration of hospital admissions and also improved quality of life. With this remote monitoring system 80% of CRI patients reported they were more/much more supported and 33 patients (75% would use this system in the future. 81% of asthmatic patients would also like to maintain this type of monitoring. The service was considered useful by the researchers. We concluded that home telemonitoring was a positive contribution to the management of chronic patients and raised awareness of it should be considered in the future.

Full Text Available The ongoing accumulation of industrial waste speaks to the need to seek cost-effective disposal methods. Brick manufacture would appear to be particularly promising in this regard. The present study analyzes the possibility of recycling the sludge generated in porcelain tile polishing, as well as coal, steel and municipal incinerator ash to make a special type of facing brick whose properties readily accommodate a full analysis of all the problems deriving from the incorporation of residue in its manufacture. Physical-chemical, mechanical and structural analyses were performed on bricks made with varying percentages of the different types of waste considered. This first paper reports the results of the physical arid technological characterization of the products; the second part of the research will address their chemical, mechanical and structural properties.

El continuo aumento de la cantidad de residuos (desechos que se generan en los procesos industriales induce a buscar nuevos métodos alternativos a la disposición final que sean altamente eficientes y a bajo costo. La industria manufac turera de ladrillos resulta muy prometedora desde este punto de vista. En este trabajo ha sido investigada la posibilidad de usar distintos residuos industriales, entre ellos barros de pulido del gres porcelánico. cenizas de carbón, cenizas de acerías y de incinerador municipal para la fabricación de ladrillos de exteriores. Fueron analizados los problemas que podrían derivar al introducir estos residuos en la pasta. En particular, en esta primera parte del trabajo se muestran los resultados derivados de la introducción de los residuos considerados, en distintos porcentajes, sobre las propiedades físicas y tecnológicas del producto final. En la segunda parte se desarrollarán los efectos causados sobre las propiedades químicas, mecánicas y microestructurales.

Long-term field experiments and science-based tools that characterize soil status (namely the soil quality indices, SQIs) assume a strategic role in assessing the effect of agronomic techniques and thus in improving soil management especially in marginal environments. Selecting key soil variables able to best represent soil status is a critical step for the calculation of SQIs. Current studies show the effectiveness of statistical methods for variable selection to extract relevant information deriving from multivariate datasets. Principal component analysis (PCA) has been mainly used, however supervised multivariate methods and regressive techniques are progressively being evaluated (Armenise et al., 2013; de Paul Obade et al., 2016; Pulido Moncada et al., 2014). The present study explores the effectiveness of partial least square regression (PLSR) in selecting critical soil variables, using a dataset comparing conventional tillage and sod-seeding on durum wheat. The results were compared to those obtained using PCA and stepwise discriminant analysis (SDA). The soil data derived from a long-term field experiment in Southern Italy. On samples collected in April 2015, the following set of variables was quantified: (i) chemical: total organic carbon and nitrogen (TOC and TN), alkali-extractable C (TEC and humic substances - HA-FA), water extractable N and organic C (WEN and WEOC), Olsen extractable P, exchangeable cations, pH and EC; (ii) physical: texture, dry bulk density (BD), macroporosity (Pmac), air capacity (AC), and relative field capacity (RFC); (iii) biological: carbon of the microbial biomass quantified with the fumigation-extraction method. PCA and SDA were previously applied to the multivariate dataset (Stellacci et al., 2016). PLSR was carried out on mean centered and variance scaled data of predictors (soil variables) and response (wheat yield) variables using the PLS procedure of SAS/STAT. In addition, variable importance for projection (VIP

Land-use change has led to a dramatic decrease in total forest cover, contributing to biodiversity loss and changes of ecosystems' functions. Insect communities of medical importance can be favored by anthropogenic alterations, increasing the risk of novel zoonotic diseases. The response of mosquito (Diptera: Culicidae) abundance and richness to five land-use types (shade coffee plantation, cattle field, urban forest, peri-urban forest, well-preserved montane cloud forest) and three seasons ("dry", "rainy" and "cold") embedded in a neotropical montane cloud forest landscape was evaluated. Standardized collections were performed using 8 CDC miniature black-light traps, baited with CO2 throughout the year. Generalized additive mixed models were used to describe the seasonal and spatial trends of both species richness and abundance. Rank abundance curves and ANCOVAs were used to detect changes in the spatial and temporal structure of the mosquito assemblage. Two cluster analyses were conducted, using 1-βsim and the Morisita-Horn index to evaluate species composition shifts based on incidences and abundances. A total of 2536 adult mosquitoes were collected, belonging to 9 genera and 10 species; the dominant species in the study were: Aedes quadrivittatus, Wyeomyia adelpha, Wy. arthrostigma, and Culex restuans. Highest richness was recorded in the dry season, whereas higher abundance was detected during the rainy season. The urban forest had the highest species richness (n = 7) when compared to all other sites. Species composition cluster analyses show that there is a high degree of similarity in species numbers across sites and seasons throughout the year. However, when considering the abundance of such species, the well-preserved montane cloud forest showed significantly higher abundance. Moreover, the urban forest is only 30 % similar to other sites in terms of species abundances, indicating a possible isolating role of the urban environment. Mosquito

Full Text Available The development of advanced materials, with complex microstructures, is a permanent challenge to the development and application of new efficient techniques for microstructural characterization. In ceramic coatings on metals, there exist a differential ion-milling ratio between both components, limiting in principle the use of conventional techniques. In this work, we report on a comparative study of TEM sample preparation techniques for plasma-sprayed ceramic coatings. Firstly, we have used a procedure derived from the conventional one (polishing, dimpling, ion milling, and alternatively a new technique using focused ion-beam milling. The material selected for this study is fine-grained alumina that was plasmasprayed on a steel substrate. The efficiency of both techniques is discussed along with the most significant microstructural features of the material subject of study.

El desarrollo de materiales avanzados, con microestructuras cada vez más complejas, supone un reto constante de desarrollo y aplicación de técnicas que permitan el análisis de la microestructura de forma eficiente. En el caso de los recubrimientos cerámicos sobre substrato metálico, la diferente velocidad de adelgazamiento iónico que suelen mostrar ambos sistemas supone, en principio, una limitación sustancial. En este trabajo, presentamos un estudio comparativo de la fabricación de láminas delgadas para microscopía electrónica de transmisión, empleando en primer lugar una técnica derivada de la convencional (desbaste, pulido y adelgazamiento iónico, y alternativamente una novedosa técnica de ataque selectivo mediante un haz iónico. El material elegido para realizar este estudio ha sido un recubrimiento de óxido de aluminio de grano fino proyectado por el método de plasma sobre acero. Se discute la eficiencia de cada una de las técnicas, así como las carácteristicas microstructurales más destacadas en el material objeto de estudio.

Boschi, A. O.

2010-10-01

Full Text Available The low porosity of porcelain tile is the result of strict control of the material’s processing conditions (milling of raw materials, compaction and sintering and the characteristics of the raw materials used in its formulation (formation of liquid phases. Sealed pores remaining after the manufacturing process are revealed at the surface after polishing and are the main factor responsible for staining the product. The porous microstructure of the sintered material depends on the characteristics of the porous microstructure of the green compact and on how the densification process evolves during sintering. The present work evaluated how the size distribution of spray-dried granules acts upon the porous microstructure of green compacts and of polished porcelain tile. The results revealed that minor adjustments in the granulometric distribution curve can reduce the visibility of stains on the polished surface, thus improving this property.

Lešnjak, A.

2002-06-01

Full Text Available Plasma spot welding of ferritic stainless steels is studied. The study was focused on welding parameters, plasma and shielding gases and the optimum welding equipment. Plasma-spot welded overlap joints on a 0.8 mm thick ferritic stainless steel sheet were subjected to a visual examination and mechanical testing in terms of tension-shear strength. Several macro specimens were prepared. Plasma spot welding is suitable to use the same gas as shielding gas and as plasma gas, i.e., a 98 % Ar/2 % H ₂ gas mixture. Tension-shear strength of plasma-spot welded joints was compared to that of resistance-spot welded joints. It was found that the resistance welded joints withstand a somewhat stronger load than the plasma welded joints due to a larger weld spot diameter of the former. Strength of both types of welded joints is approximately the same.

coefficients de diffusion mesures experimentalement; il est permis d'en conclure que le coefficient d'autodiffusion du chrome est insensible aux modifications de la teneur en chrome de l'alliage Inor-8. (author) [Spanish] Si se someten el Inconel o el Inor-8 a la accion de una mezcla de fluoruros fundidos, que contenga sustancias reducibles, el cromo sufre una oxidacion selectiva y es extraido de la aleacion. Con ayuda del indicador radiactivo {sup 51}Cr, los autores han evaluado los coeficientes de autodifusion del cromo en el Inconel y en el lnor-8, y han comprobado que los datos obtenidos son validos para las aleaciones expuestas a la corrosion. Han calculado los coeficientes globales 1) midiendo el paso del {sup 51}Cr de las capsulas de aleacion (empleado en forma do CrF{sub 2}) a los fluoruros no corrosivos fundidos, y 2) comparando la radiactividad total medida en las muestras de aleacion expuestas con la radiactividad de la sal a cuya accion fueron sometidas.

Full Text Available The excavation of barrow 1 of Chousa Nova, Silleda, Pontevedra (NW Spain offered surprising results. This mound, in spite of experiencing a large number and types of anthropic damage, still preserved a great constructive complexity. Within its megalithic chamber, formed by 5 granite orthostats and a large roofing slab of, also in granite, a set of archaeological materials appeared. These were an axe, a chisel and a polishing stone, with a set of 35 beads, most of them of a green stone and the rest of an organic material, with an extremely high degree of alteration, inserted between them. The analytical techniques have been in all cases not-destructives (X-ray diffraction and fluorescence spectroscopy, infrared spectroscopy, optical microscopy and environmental electronic microscopy, with microanalysis. The archaeometric analysis results show a mineralogical nature of these materials, based in variscite and amber. The textural and compositional features are very homogeneous between each assemblage of beads. The importance of the alteration phenomena and dissolution of the archaeological objects are determined and quantified. This alteration is due to an intense chemical attack during the burial periods. The possible source areas of provenance for these materials are also discussed on the basis of geochemical data obtained in the analysis.

Full Text Available Gris Pulpis is a Jurassic microcrystalline limestone found in the Maestrazgo Area of the Iberian Mountain Range (province of Castellón, Spain. This paper reports the results of a detailed study of the mineralogical, pelrographic and chromatic characteristics, as well as the durability, of this stone, classified as a commercial marble for its polish ability. The study determined the relationship between the structural characteristics of the stone, with a proliferation of stylolites and veins, and its physical properties. Its flexura I strength was found to be greater than would normally be expected in a structure with such a dense web of stylolites and veins. This is due to the structural and mineralogical properties of these stylolites, characterised by an extremely wavy design, scant mineral infillings and, occasionally, subsequent cementation. The characteristics of the porous media of homogeneous microcrystalline limestones such as Gris Pulpis largely explain the durability of this stone when exposed to freeze-thaw cycles and salt crystallisation. These arc the properties that make Gris Pulpis limestone, quarried in the Spanish Region of Valencia, a valuable building material for both architectural and civil engineering applications

Soil structure is the key factor that determine the soil quality as control the organic matter turnnover, soil biology and soil erodibility (Cerdà, 1996; 1998; Wick et al., 2014; Gelaw, 2015). There is a need to understand better the factors and the processes that act on the soil aggregation and the dynamics of the soil aggregation, which will make easier to understand the soil system functioning (Jordán et al., 2011; Jordán et al., 2012; Pulido Moncada et al., 2013). Fire, mines, grazing and agricultura (Cerdà, 2000; Mataix Solera et al., 2011; Cerdà et al., 2012; Hallett et al., 2014; Lozano et al., 2013) determines how the soil structure is highly affected by the humankind. And this determines the sustainability of the land managements (García Orenes et al., 2012; K¨ropfl et al., 2013; Mekuria and Aynekulu, 2013; Taguas et al., 2013; Zhao et al., 2013). Aggregates are Small And Well Organized (SAWO) structures that allow the water to flow, the air fill the porous and the life to be diverse and abundant in the soil. The SAWO avatar will teach the importance of the functions and the services of the aggregates to students and other scientists, but also to any audience. This means that the experiments and the vocabulary to be used by SAWO will be very wide and rich. The Avatar SAWO will use different strategies and skills to teach the soil aggregation properties and characteristics. And also, how to measure. Easy to carry out experiments will be shown by SAWO to measure the aggregate stability in the field and in the laboratory, and the soil sampling in the field. The SAWO avatar will play a special attention to the impact of forest fires on aggregate stability changes and how to measure. The SAWO avatar will teach how to take samples in the field, how to transport and manage in the laboratory, and finally which measurements and test can be done to determine the aggregate stability.

The Dehesa is the most widespread agroforestry land-use system in Europe, covering more than 3 million hectares in the Iberian Peninsula and Greece (Grove and Rackham, 2001; Papanastasis, 2004). It is an agro-silvo-pastural ecosystem consisting of widely-spaced oak trees (mostly Quercus ilex L.), combined with crops, pasture and Mediterranean shrubs, and it is recognized as an example of sustainable land use and for his importance in the rural economy (Diaz et al., 1997; Plieninger and Wilbrand, 2001). The ecosystem is influenced by a Mediterranean climate, with recurrent and severe droughts. Over the last decades the Dehesa has faced multiple environmental threats, derived from intensive agricultural use and socio-economic changes, which have caused environmental degradation of the area, namely reduction in tree density and stocking rates, changes in soil properties and hydrological processes and an increase of soil erosion (Coelho et al. 2004; Schnabel and Ferreira, 2004; Montoya 1998; Pulido and Díaz, 2005). Understanding the hydrological, atmospheric and physiological processes that affect the functioning of the ecosystem will improve the management and conservation of the Dehesa. One of the key metrics in assessing ecosystem health, particularly in this water-limited environment, is the capability of monitoring evaporation (ET). To make large area assessments requires the use of remote sensing. Thermal-based energy balance techniques that distinguish soil/substrate and vegetation contributions to the radiative temperature and radiation/turbulent fluxes have proven to be reliable in such semi-arid sparse canopy-cover landscapes. In particular, the two-source energy balance (TSEB) model of Norman et al. (1995) and Kustas and Norman (1999) has shown to be robust for a wide range of partially-vegetated landscapes. The TSEB formulation is evaluated at a flux tower site located in center Spain (Majadas del Tietar, Caceres). Its application in this environment is

In order to design adaptive strategies to global change we need to assess the future impact of climate change on water resources, which depends on precipitation and temperature series in the systems. The objective of this work is to generate future climate series in the "Alto Genil" Basin (southeast Spain) for the period 2071-2100 by perturbing the historical series using different statistical methods. For this targeted we use information coming from regionals climate model simulations (RCMs) available in two European projects, CORDEX (2013), with a spatial resolution of 12.5 km, and ENSEMBLES (2009), with a spatial resolution of 25 km. The historical climate series used for the period 1971-2000 have been obtained from Spain02 project (2012) which has the same spatial resolution that CORDEX project (both use the EURO-CORDEX grid). Two emission scenarios have been considered: the Representative Concentration Pathways (RCP) 8.5 emissions scenario, which is the most unfavorable scenario considered in the fifth Assessment Report (AR5) by the Intergovernmental Panel on Climate Change (IPCC), and the A1B emission scenario of fourth Assessment Report (AR4). We use the RCM simulations to create an ensemble of predictions weighting their information according to their ability to reproduce the main statistic of the historical climatology. A multi-objective analysis has been performed to identify which models are better in terms of goodness of fit to the cited statistic of the historical series. The ensemble of the CORDEX and the ENSEMBLES projects has been finally created with nine and four models respectively. These ensemble series have been used to assess the anomalies in mean and standard deviation (differences between the control and future RCM series). A "delta-change" method (Pulido-Velazquez et al., 2011) has been applied to define future series by modifying the historical climate series in accordance with the cited anomalies in mean and standard deviation.

Estimation of slip scenarios of mega-thrust earthquakes and strong motion simulations for Central Andes, Peru

We have developed a methodology for the estimation of slip scenarios for megathrust earthquakes based on a model of interseismic coupling (ISC) distribution in subduction margins obtained from geodetic data, as well as information of recurrence of historical earthquakes. This geodetic slip model (GSM) delineates the long wavelength asperities within the megathrust. For the simulation of strong ground motion it becomes necessary to introduce short wavelength heterogeneities to the source slip to be able to efficiently simulate high frequency ground motions. To achieve this purpose we elaborate "broadband" source models constructed by combining the GSM with several short wavelength slip distributions obtained from a Von Karman PSD function with random phases. Our application of the method to Central Andes in Peru, show that this region has presently the potential of generating an earthquake with moment magnitude of 8.9, with a peak slip of 17 m and a source area of approximately 500 km along strike and 165 km along dip. For the strong motion simulations we constructed 12 broadband slip models, and consider 9 possible hypocenter locations for each model. We performed strong motion simulations for the whole central Andes region (Peru), spanning an area from the Nazca ridge (16^o S) to the Mendana fracture (9^o S). For this purpose we use the hybrid strong motion simulation method of Pulido et al. (2004), improved to handle a general slip distribution. Our simulated PGA and PGV distributions indicate that a region of at least 500 km along the coast of central Andes is subjected to a MMI intensity of approximately 8, for the slip model that yielded the largest ground motions among the 12 slip models considered, averaged for all assumed hypocenter locations. This result is in agreement with the macroseismic intensity distribution estimated for the great 1746 earthquake (M~9) in central Andes (Dorbath et al. 1990).

Full Text Available Resumo: Introdução: A tuberculose extensivamente resistente (TBXDR define-se como uma forma de tuberculose multirresistente (TBMR com resistências adicionais às fluoroquinolonas e, pelo menos, a um dos antibacilares injectáveis seguintes: amicacina, canamicina e capreomicina. Foi classificada pela OMS como uma ameaça séria ao controlo da tuberculose, com consequências à escala mundial, assumindo os contornos de uma autêntica pandemia em algumas regiões do globo.Objectivo: Comparar os doentes com TBXDR versus outros perfis de TBMR no que diz respeito às características demográficas e epidemiológicas, factores etiopatogénicos e evolução no internamento.Material e métodos: Doentes internados no Serviço de Pneumologia III do Hospital de Pulido Valente no período compreendido entre Abril de 1999 e Junho de 2007, com o diagnóstico de TBMR microbiologicamente confirmado. Foram analisadas as seguintes variáveis: sexo, distribuição etária, raça, formas de apresentação da TB, grupos de tratamento, perfil de resistência aos antibacilares, estatuto de imigrante, número e duração de tratamentos anteriores, classificação OMS, co-infecção VIH, alcoolismo e/ou toxicodependência, demora média do internamento e mortalidade intra-hospitalar. A análise estatística realizou-se no programa SPSS (Statistical Package for the Social Sciences, versão 15.0. Nas variáveis categoriais, as diferenças estatísticas entre os grupos foram avaliadas através do teste qui-quadrado e as variáveis numéricas através do teste t. Para a construção do modelo preditivo da presença de TBXDR (variável dependente foi utilizada a análise de regressão logística, tendo sido incluídas as seguintes variáveis independentes: classificação OMS, coinfecção VIH, estatuto de imigrante, alcoolismo e/ou toxicodepend

Full Text Available RESUMO: Na década de 60 surgiram na América do Norte as primeiras Unidades de Cuidados Intermédios (UCInts como resposta à pressão na gestão dos internamentos e aos custos crescentes das camas das Unidades de Cuidados Intensivos (UCIs. O novo modelo de organização proposto estabelece uma hierarquização dos diferentes níveis de cuidados – Enfermaria, UCInts e UCIs – com base nos recursos materiais e humanos disponibilizados, tendo como objectivo a continuidade no tratamento hospitalar, sem perda de qualidade nem impacto negativo no resultado final, representando uma alternativa, com uma relação custo/eficácia favorável, para um número significativo de doentes.As UCInts respiratórias são vocacionadas para o tratamento de doentes ventilados mecanicamente, estáveis, para desmame ou tratamento crónico; para os doentes hemodinamicamente estáveis com doença subjacente com potencial para agravamento da insuficiência respiratória, requerendo observação frequente e/ou ventilação por pressão positiva contínua por máscara; para os doentes que requerem monitorização frequente dos sinais vitais ou de fisioterapia respiratória intensiva.O Serviço de Insuficientes Respiratórios (SIR do Departamento de Pneumologia do Hospital de Pulido Valente é constituído por uma Enfermaria com 26 camas, 8 das quais de Cuidados Intermédios (CInts, uma Unidade de Cuidados Intensivos (UCIP e um Hospital de Dia para Insuficientes Respiratórios (HDIR.No sentido de avaliar o trabalho realizado nos CInts, efectuou-se uma revisão do arquivo clínico de todos os doentes aí internados, entre 1 de Janeiro de 1995 e 31 de Dezembro de 2000.Resultados: neste período registaram-se 545 internamentos (167 mulheres e 378 homens, com uma idade média de 64 anos (14-92. Em 34% dos casos os doentes eram provenientes da UCIP, em 19% da Enfermaria e em 4% do

In total 39.73% of the area covered was classified as optimal potential for "regulating" ES, 40.19% for "providing" ES and 31.91% for "cultural" ES. These results suggested that ES regulating, providing and cultural ES are located in specific regions, and according to optimal areas assessment, an important area of Vilnius had high potential to provide very good ES. These results are important for a better planing of these areas in order to maintain the quality of these services. References Beniston, J.W., Lal, R., Mercer, K.L.

There were 6 cases of associated neoplastic disease (18,8% and 5 patients with COPD (15,6%. The cause of death was attributed to AIDS or TB in 14 patients (43,8% and unrelated to tuberculosis in 18 patients (56,2%.Conclusions: Our data suggest that TB as a cause of death was associated with advanced age, in patients with no prior treatment history and without hospital complications. On the contrary, the group which death resulted from AIDS was formed by younger patients with noncompliant prior treatments. A significant increase of GOT levels was associated with cardiovascular complications (acute pulmonary embolism and arrhythmia and low hemoglobin concentration predicted infectious complications (nosocomial pneumonia and opportunistic infections.REV PORT PNEUMOL 2002; VIII (3 Palavras-chave: Tuberculose, mortalidade, tuberculose multirresistente, infecção VIH, Key-words: Tuberculosis, in-hospital mortality, multidrug-resistant tuberculosis, HIV infection
