    The El Paso Paul Kayser, the world's largest LNG carrier, demonstrates not only the sophistication and skills of French shipbuilding technology but also the financial perils of the LNG game. Ordered along with 2 sister ships to transport LNG from Algeria to the US, the ship must now await the start-up of the new Kikda LNG plant, which has been delayed for an estimated 18 months. The Paul Kayser has a cargo capacity of 4.4 million cu ft, measures 922 ft overall, and has a deadweight of some 59,000 tons. The tanks were constructed according to the Gaz Transport technique using a double hull with Invar membranes. Labor involved with construction of the LNG tanks is estimated at 580,000 man-hr.

  5. Paso elevado, en Krahnenberg

    1965-02-01

    Full Text Available A bypass on the general highway is now being built near Andernach, Germany. It is about 1100 m long, and includes an elevated way. The design has been influenced by the poor soil resistance, and the fact that the road is built on a mountainside. The elevated way runs along a curve, with a minimum radius of 475 m, and is subdivided into 34 sections, each 31.75 m long. The deck consists of a box girder, separated into two compartments, and is of prestressed concrete. The deck cantilevers on each side of the longitudinal structure, and has a total width of 18.20 m. This allows for two separate pavements, a central separating section, and two lateral sidewalks. The construction procedure was significant. Owing to the nature of soil, and the need to avoid heavy concentrated loads, the traditional system of formwork was substituted by the Gerber procedure. This consists of 4 metal open girders which rest on the columns, which had been previously constructed. These beams, which are capable of conforming to the curvature of the road, are moved along the axis of the deck, with the aid of hydraulic jacks, as the process of concreting proceeds. A crane, with an operational reach of 35 m served to supply the materials and formwork at the various construction points.En las proximidades de Andernach (Alemania se está construyendo una derivación de la carretera general, con unos 1.100 m de longitud total, que consiste en una especie de puente o paso elevado. Se justifica esta solución particular por la poca consistencia del terreno y el especial trazado a media ladera. El eje del paso elevado sigue una alineación curva con radio mínimo de 475 m, y está subdividido en 34 tramos de 31,75 m de luz. El conjunto que forma el tablero es una viga cajón, bicelular, de hormigón pretensado y grandes salas en voladizo que dan una anchura total de 18,20 m, lo cual permite la habilitación de dos bandas de circulación separadas por un macizo central y dos andenes

    Full Text Available Las técnicas de análisis cualitativo tienen cada vez más importancia en el ámbito de las ciencias sociales. A partir de su integración orgánica con el proceder general de la investigación naturalista, se convierten en parte de las herramientas más recurridas al momento de explicar fenómenos sociales complejos. Sin embargo, la dificultad para comprender y utilizar independientemente el análisis cualitativo de datos de la matriz disciplinaria que la sostiene, demanda a quienes investigan tener profundos conocimientos no sólo respecto de su uso, sino también de sus múltiples y a veces divergentes fundamentos epistemológicos y teórico-estratégicos. En este artículo se presenta una técnica de análisis, el análisis de contenido en su vertiente cualitativa, que pretende ser una propuesta analítica intermedia menos sujeta a los supuestos naturalistas de investigación, en virtud de la extendida aplicación que de ella se ha hecho tanto en el ámbito cuantitativo como cualitativo. En la introducción se expone una breve síntesis del aporte de este tipo de análisis, las diferentes definiciones que se han brindado de esta técnica y las pretensiones en su enfoque, tal como se concibe en este trabajo posteriormente se hace un repaso de los principales pasos de ejecución -integrando el procedimiento propio del análisis de contenido y otros métodos analíticos cualitativos que ayudan a precisarlo y enriquecerlo-; también se aborda su grado de validez y confiabilidad y comentarios finales aclaratorios de algunos aspectos tratados a lo largo de este trabajo.

  8. Paso superior en una ladera

    1965-07-01

    Full Text Available The Redwood highway, through the Californian forest, runs on a viaduct, as it crosses a mountain slope of about 45° inclination. The firm ground is fairly deep, and as an additional constructional difficulty, it was necessary to respect the natural beauty of the countryside. A structure of portal frames were built, forming a number of short spans. These spans were bridged with metal girders, on which a 19 m wide deck was placed. The columns are hollow and have a transversal cross beam, to join each pair. There was difficulty in excavating the foundations for the columns, as it was necessary to dig through the soft top soil, and also prevent this soil from hurting the trunks of the forest trees. Another significant difficulty in the construction of this viaduct was the access to the working site, since there were no suitable platforms from which to operate the appropriate machinery. This made it necessary to do a lot of the work by manual operation. As one of the edges of the deck is very close to the mountain side, a supporting beam was erected on this side. It was made of concrete, on metal piles. The formwork for the deck structure was placed on the concrete stems of the supporting piles.La autopista denominada Redwood (California salva, con un paso superior, la ladera de un bosque cuya pendiente es del 1/1. El terreno firme se halla a bastante profundidad, añadiéndose, a los naturales problemas de la construcción, el imperativo de respetar la belleza agreste del paraje. La solución adoptada consiste en una estructura porticada, con varios tramos de pequeñas luces, salvados con vigas metálicas, sobre los que se coloca la losa del tablero, de 19 m de anchura total. Los soportes están constituidos por pórticos de dos montantes huecos (con bases de hormigón en masa por debajo del suelo, hasta el firme coronados por un cabezal. La perforación de pozos para el hormigonado de los montantes presentaba la dificultad de atravesar el terreno

    As part of a plan to phase out its nonutility businesses, El Paso Electric Company will discontinue its remaining PascoTex Corporation operations, consisting of the manufacture of specialty steel products, and company management released revised estimates of losses to be incurred during the disposal period. Recently El Paso announced it would also bow out of most of its nonutility real estate operations. Increased operating expenses, principally at El Paso's Palo Verde station nuclear facility, have also impacted the bottom line. All three units at Palo Verde were out of service at the time of this writing. The good news was that energy sales have increased

    Full Text Available A forte pressão provocada pela expansão urbana desordenada sobre os recursos naturais, principalmente os solos, tem provocado danos, muitas vezes de difícil reparo. A grande concentração populacional em centros urbanos cada vez maiores tem dirigido a atenção de diferentes profissionais para o recurso solo, no sentido de entender sua dinâmica para minimizar sua degradação. No entanto, a falta de conhecimento sobre as propriedades, bem como sobre a aptidão dos solos sob uso urbano tem provocado o seu mau uso, resultando em processos como compactação, erosão, deslizamentos e inundações, assim como poluição com substâncias orgânicas, inorgânicas e patógenos, aumentando os custos do desenvolvimento afetando toda a sociedade. Neste sentido, este texto discute como o conhecimento pedológico pode diminuir os efeitos negativos provocados pelo processo de urbanização.The strong pressure caused by the disordered urban expansion over the natural resources, mainly the soils, has caused damages, many times difficult to repair. The great population concentration in urban centers getting larger and larger has been driving the attention of different professionals to soil resource, in the sense of understanding its dynamics to minimize its degradation. The lack of knowledge related to the soils properties and capability promote their inappropriate use, resultig in degrading processes as compaction, erosion, sliding, floods, and organic, inorganic and patogenic pollution, increasing the cost of development and affecting the whole society. This text discusses how pedologic knowledge can reduce the negative effects caused by the urbanization process.

  7. El Paso Formation - a Lower Ordovician platform carbonate deposit

    Energy Technology Data Exchange (ETDEWEB)

    Clemons, R.E.

    1987-05-01

    The eastward-transgressive Lower Ordovician El Paso Formation conformably overlies Bliss Sandstone in southern New Mexico. Locally, lower El Paso was deposited on low hills of plutonic and volcanic rocks. The region subsided gradually throughout Canadian time, receiving the El Paso carbonate rock blanket up to 460 m thick. Lithologic and chronologic correlative rocks were deposited over most of the southwestern US as the first Paleozoic carbonate platform sequence. The El Paso Formation contains four members, listed here in ascending order: Hitt Canyon, Jose, McKelligon, and Padre. Gradually decreasing sand content upward through the Hitt Canyon indicates deepening water and/or greater distance to shore. Girvanella(.) oncolites are locally abundant. Stromatolite mounds near the top of the Hitt Canyon, combined with an influx of sand, ooids, and rounded bioclasts in the Jose Member, recorded a shoaling phase. The overlying McKelligon Member contains little or no sand, and sponge-Calathium mounds are prominent at some locales. Stromatolite mounds are interbedded with sponge-Calathium mounds in a few sections. Lower Padre Member beds are typically silty to sandy and locally contain thinly-laminated zones. The Padre contains more restricted fauna that includes traces of ostracods. Pervasive bioturbation of El Paso beds and fauna consisting of echinoderms, sponges, gastropods, trilobites, Nuia, Calathium, cephalopods, and algae plus minor brachiopods and Pulchrilamina indicate predominating shallow-subtidal environments. Low-energy platform environments, in which a large volume of micritic muds accumulated, were disturbed thousands of times by storms producing abundant thin, poorly washed biosparite, intrasparite, and intrasparrudite lenses.

    Emission inventories of ozone precursors are routinely used as input to comprehensive photochemical air quality models. Photochemical model performance and the development of effective control strategies rely on the accuracy and representativeness of an underlying emission inventory. This paper describes the tasks undertaken to compile and evaluate an ozone precursor emission inventory for the El Paso/Ciudad Juarez/Southern Dona Ana region. Point, area and mobile source emission data were obtained from local government agencies and were spatially and temporally allocated to a gridded domain using region-specific demographic and land-cover information. The inventory was then processed using the US Environmental Protection Agency (EPA) recommended Emissions Preprocessor System 2.0 (UAM-EPS 2.0) which generates emissions files compatible with the Urban Airshed Model (UAM). A top-down evaluation of the emission inventory was performed to examine how well the inventory represented ambient pollutant compositions. The top-down evaluation methodology employed in this study compares emission inventory ratios of non-methane hydrocarbon (NMHC)/nitrogen oxide (NO{sub x}) and carbon monoxide (CO)/NO{sub x} ratios to corresponding ambient ratios. Detailed NMHC species comparisons were made in order to investigate the relative composition of individual hydrocarbon species in the emission inventory and in the ambient data. The emission inventory compiled during this effort has since been used to model ozone in the Paso del Norte airshed (Emery et al., CAMx modeling of ozone and carbon monoxide in the Paso del Norte airshed.

    1945-01-01

    El Paso, Tex., and Ciudad Juarez, Chihuahua, Mexico, and the industries in -that area draw their water supplies from wells, most of which are from 600 to 800 feet deep. In 1906, the estimated average pumpage there was about 1,000,000 gallons a day, and by 1935 it had increased to 15,400,000 gallons a day. The water-bearing beds, consisting of sand and gravel interbedded wire clay, tie in the deep structural trough known as the Hueco bolson, between the Organ and Franklin Mountains on the west, the Hueco, Finlay, and Malone Mountains on the east, the Tularosa Basin on the north, and the mountain ranges of Mexico on the south. From the gorge above El Paso to that beginning near Fort Quitman, about 90 miles southeast .of El Paso, the Rio Grande has eroded a flat-bottomed, steepwalled valley, 6 to 8 miles wide and 225 to 350 feet deep. No other large drainage channels have been developed on the bolson. The valley is known as the El Paso Valley, and the uneroded upland part of the bolson is called the Mesa. In the lowest parts of the El Paso Valley, the water-table is nearly at the surface. The quality of the underground water in the valley varies greatly both vertically and laterally. To a depth of about 400 to 500 feet it is in general too highly mineralized for municipal use, but between about. 500 and 900 feet good water may be obtained from several beds. In the beds between 500 and 900 feet the water level in wells is in places as. much as 20 feet lower than that in the shallow beds. Beneath the Mesa the water level .varies from about 200 feet beneath the surface, where the ground elevation is least, to about 400 feet. where it is highest. The water beneath the Mesa in general is of satisfactory quality and contains less than 500 parts per million of dissolved solids. Two cones of depression in the water table have been formed by the pumping near El Paso--one m the vicinity of the Mesa well field, the other around the Montana well field in the valley. The water

    1992-01-01

    El Paso Natural Gas Co.'s largest expansion program in its 64-year history will be completed along its northern system this spring or early summer. According to the company, the three-tiered, $241.5 million expansion program will increase El Paso's gas-transport capacity by 835 MMcfd to 2.5 bcfd of conventional and coal-seam gas from the San Juan basin in northwestern New Mexico. That's enough natural gas, says the company, to supply the needs of a city of more than 800,000 residents. This paper reports that the expansion involves the San Juan Triangle system, the company's northern main line, and the Permian-San Juan crossover line. The company also filed with the Federal Energy Regulatory Commission (FERC) in October 1991 to construct a new $15.2 million compressor station, Rio Vista, south of Bloomfield, N.M. The station would be used to move additional gas to the main line

    The mission of Paso de las Piedras was due of the radioactive values found by the French mission of the CE.A. found in a few former polls .Analyzed the samples its gave values that range between 2.500 and 3.000 ppm in uranium. The need to come to prospectar this zone was immediate, to determine if wil be before a deposit of uranium. The later studies prove that the extension was limited and not concluded yet. There were compiled 5 classes of numerical information in order of increasing detail: a) Chemical analysis of samples of alluvium b) chemical analysis of water samples c) report radiometric d) chemical analysis and radiometric report of soils e) chemical and radiometric analysis of the perforations

    Strange, J.

    1998-01-01

    El Paso's three part strategy of dealing with recontracting was described. The strategy involves (1) a rate case initiative, (2) internal restructuring, and (3) a marketing initiative. As a result of the rate case initiative, cost of service was reduced by $ 70 million, while maintaining the lowest rates in California. The internal restructuring resulted in eliminating all activities that did not add value, streamlined all business processes, flattened the organization structure, reduced personnel complement from 2400 to 1500, and paved the way for outsourcing many services. Largely as a result of the marketing initiative, 100 per cent of returned capacity has been sold for 1998 and 1999, compared to 84 per cent during 1996 and 1997. The company is now able to concentrate on projects for the east-of-California and northern Mexico markets, and to lay the groundwork in California for selling the returned capacity in 2000 and beyond. 2 tabs., 5 figs

    Full Text Available La distinción entre metodología cuantitativa y cualitativa define dos campos de investigación que profesan postulados paradigmáticos encontrados. El conocimiento científico se caracteriza por ser racional y objetivo, fáctico y verificable, caracterización que sintoniza, en buena medida, con los atributos del método cuantitativo. Por el contrario, el estudio cualitativo busca comprender los fenómenos dentro de su ambiente usual, utilizando como datos descripciones de situaciones, eventos, personas, interacciones, documentos, etc. Este enfoque se utiliza para descubrir y refinar preguntas de investigación, pero solo a veces se ponen a prueba las hipótesis. En este trabajo se analizan las principales características de las metodologías cuantitativa y cualitativa, y se discute la importancia de asegurar el control y la rigurosidad científica al analizar los fenómenos complejos del comportamiento.

    The availability of fresh ground water in El Paso and adjacent areas that is needed to meet increased demand for water supply concerns local, State, and Federal agencies. The Hueco bolson is the principal aquifer in the El Paso area. Starting in the early 1900s and continuing to the 1950s, most of the municipal and industrial water supply in El Paso was pumped from the Hueco bolson aquifer from wells in and near the Rio Grande Valley and the international border. The Rio Grande is the principal surface-water feature in the El Paso area, and a major source of recharge to the shallow aquifer (Rio Grande alluvium) within the study area is leakage of flow from the Rio Grande.

Si concebimos ese espacio sólo como un mercado informacional (acceso y contenidos, los indicadores que miden el desarrollo de la SI serán cuantitativos y tendrán un claro sesgo mercantilista. En cambio, si promovemos una sociedad civil de la información, tendremos que usar indicadores cualitativos que midan el desarrollo de la vida civil en el espacio electrónico y las capacidades de la ciudadanía por ser activa en él. Como ejemplo, se analiza críticamente el plan europeo e-Learning y los indicadores utilizados por la Unión Europea, centrados en la conexión a internet y el uso de las tecnologías multimedia. Partiendo de que la educación debe desarrollar ante todo las capacidades de acción en el espacio electrónico, se proponen indicadores cualitativos para la educación asistida por las TIC.

    Full Text Available RESUMEN: En las ciencias sociales el tema de la complejidad se presenta con frecuencia en el marco de la discusión entre los paradigmas cuantitativo y cualitativo y en ese debate, casi siempre, es asociado con este último, sobre la base de que la complejidad implica, necesariamente, asumir un enfoque holístico, idiográfico, no reduccionista y comprensivo en las ciencias sociales. El presente artículo se propone argumentar en contra de ese supuesto mostrando que no se requiere ningún desplazamiento paradigmático hacia el enfoque cualitativo para asumir una visión compleja en las ciencias sociales. ABSTRACT: n social sciences, the subject of complexity arises frequently in the context of the discussion between the quantitative and qualitative paradigms and in that debate, it is almost always associated with the latter, on the basis, that complexty necessarily implies, taking a holistic, idiographic approach, not reductionist or comprehensive in the social sciences. This article intends to argue against that assumption, showing that any paradigm shift towards the qualitative approach is not required to assume a complex vision in social sciences.

    Implementing programs that target primary prevention of chronic diseases is critical for at-risk populations. Pasos Adelante, or "Steps Forward," is a curriculum aimed at preventing diabetes, cardiovascular disease, and other chronic diseases in Hispanic populations. Pasos Adelante is adapted from the National Heart, Lung, and Blood Institute's cardiovascular disease prevention curriculum, Su Corazon, Su Vida, and includes sessions on diabetes and community advocacy and incorporates walking clubs. The Pasos Adelante curriculum was implemented in two Arizona, United States-Sonora, Mexico border counties. Key issues in these communities are safety, access to recreational facilities, climate, and cultural beliefs. Pasos Adelante is a 12-week program facilitated by community health workers. The program includes interactive sessions on chronic disease prevention, nutrition, and physical activity. Evaluation of the program included precurriculum and postcurriculum questionnaires with self-reported measures of physical activity and dietary patterns. Approximately 250 people participated in the program in Yuma and Santa Cruz counties. Postprogram evaluation results demonstrate a significant increase in moderate to vigorous walking among participants and shifts in nutritional patterns. The Pasos Adelante program demonstrates that an educational curriculum in conjunction with the support of community health workers can motivate people in Arizona/Sonora border communities to adopt healthy lifestyle behaviors.

    Studies have highlighted differences in the victim choice, offender, and offense characteristics of female and male sexual offenders. However, little is known about how solo and co-offending females differ from solo male sexual offenders. We compared the characteristics of 20 solo and 20 co-offending females (co-offended with a male and/or female accomplice), and 40 male sexual offenders against children. We found that solo female offenders showed the most evidence of personal problems, including depression and sexual dissatisfaction. Compared with male offenders, female co-offenders showed poorer self-management, but better sexual self-regulation. Male offenders had a greater history of offending and showed more evidence of sexual abuse supportive cognitions relative to both solo and co-offending females. These results are consistent with the need for a gender-specific approach to working with sexual offenders and may have implications for understanding the often complex treatment needs of these clients.

    Jones, Elaine C; Evans, David A

    2015-04-01

    Changes in health care are having a dramatic effect on the practice of medicine. In 2005, a National Center for Health Statistics survey showed that 55%-70% of physicians are in small/solo practices. These data also demonstrated that 70% of physicians identified themselves as owners. Since passage of the Affordable Care Act (ACA) in 2010, neurologists report an 8% increase in academic practice settings, a 2% decrease in private practice settings, and a 5% decrease in solo practice settings. Surveys of family physicians showed that 60% are now employees of hospitals or larger groups. A survey by The Physicians Foundation showed that 89% of physicians believed that the traditional model of independent private practice is either "on shaky ground" or "a dinosaur soon to go extinct." With the changes expected from the ACA, solo/small practices will continue to face challenges and therefore must pay close attention to business and clinical metrics.

    The 1996 Paso del Norte (PdN) ozone study was conducted to improve current understanding of the significant meteorological and air quality processes that lead to high concentrations of ozone in El Paso, Texas (USA) and Ciudad Juárez, Chihuahua (Mexico). Two-hour canister samples were collected five times daily at 05.00-07.00 h, 07.00-09.00 h, 09.00-11.00 h, 11.00-13.00 h, and 15.00-17.00 h MST during intensive study periods at one urban and one rural site on each side of the border. An automated gas chromatograph was operated at one site in central El Paso. Source profiles (the fractional chemical composition of emissions) from motor vehicles, gasoline, liquefied petroleum gas, and commercial natural gas were combined with source profiles from other studies for input to the Chemical Mass Balance (CMB) receptor model to apportion the measured non-methane hydrocarbons (NMHC) to sources. On-road vehicle emissions accounted for one-half to two-thirds of the NMHC in Ciudad Juárez and El Paso with the highest contributions occurring during the morning and afternoon commute periods. Emissions from diesel exhaust contributed approximately 2-3% of NMHC in Ciudad Juárez and less than 2% in El Paso. The average sum of liquid gasoline and gasoline vapor increased during the day in Ciudad Juárez from 2% at 06.00 h to approximately 12% at 16.00 h. Diurnal and day-of-the-week patterns in the liquid gasoline contributions are essentially identical to the corresponding patterns for motor vehicle exhaust, which suggest that a large fraction of the liquid gasoline contribution may be associated with tailpipe emissions rather than evaporative emissions from motor vehicles or industrial sources. Including the sum of the two sources put the upper limit for tailpipe contributions at 60-70% of NMHC.

The secondary files referred to the document of local, national and international historians (examples: Ricklefs, Lombard, Vorstensteden, Muljana, Notosusanto, Kartodirdjo, Sajid and Javanese architecture researchers (Ronald, Ikaputra, Adishakti. While the physical files referred to the field research that was conducted by interviews and collecting the artefacts. The main findings of study of morphology in the city of Solo were: the 'skeleton' element grew in three formations (central, cluster and organic; the 'meat' element grew in three formations also (horizontal, vertical, and interstitial; and the 'blood' element increased from the native people (Javanese, Madura, Banjar to foreign people (Chinese, Arab, India, Dutch and changed from agricultural to non-agricultural activities. The other findings were the city of Solo was constructed by a-three-concept of urban design as follows: the organic concept which was conducted by native people; the colony concept which was conducted by the Dutch; and the cosmology concept which was conducted by the Javanese Kingdom.

    2010-01-01

    The Columbia Hills soils have been exposed to aqueous alteration in alkaline [1] as well as acid conditions [2,3]. The Paso Robles class soils are bright soils that possess the highest S concentration of any soil measured on Mars [2]. Ferric-sulfate detection by Moessbauer analysis indicated that acid solutions were involved in forming these soils [4]. These soils are proposed to have formed by alteration of nearby rock by volcanic hydrothermal or fumarolic activity. The Paso Robles soils consist of the original Paso Robles-disturbed-Pasadena (PR-dist), Paso Robles- PasoLight (PR-PL), Arad-Samra, Arad-Hula, Tyrone- Berker Island1 and Tyrone-MountDarwin [2 ,3. ]Chemical characteristics indicate that the PR-dist and PR-PL soils could be derived from acid weathering of local Wishstone rocks while the Samra and Hula soils are likely derived from local Algonquin-Iroquet rock [3]. The Paso Robles soils were exposed to acidic sulfur bearing fluids; however, little else is known about the chemistry of the alteration fluid and its effects on the alteration of the proposed parent materials. The objectives of this work are to conduct titanium normalized mass-balance analysis to1) assess elemental gains and losses from the parent materials in the formation of the Paso Robles soils and 2) utilize this information to indicate the chemical nature of the alteration fluids.

El objetivo fue identificar los factores asociados al no autocuidado en hombres con muerte prematura y diagnóstico de DMT2. Materiales y Métodos: Se realizaron seis entrevistas cualitativas a familiares de hombres con DMT2 que fallecieron por complicaciones de su enfermedad, utilizando la metodología de la autopsia verbal. Los resultados se analizaron mediante el análisis de contenido. Resultados: Dentro de los factores que surgieron como limitantes para el autocuidado fueron: la negación de la DMT2, el trabajo, el machismo, preferencia en los alimentos, apoyo familiar, el consumo de alcohol, el consumo de tabaco y la depresión. Discusión: Los hombres con DMT2 se ven influenciados por diversas circunstancias que limitan cuidarse, atenderse y por consiguiente presentar desventajas de salud, complicaciones e incluso una muerte temprana. Conclusiones: Desde la perspectiva de enfermería los resultados ayudan a comprender el comportamiento de los hombres ante esta enfermedad en donde se requiere cuidado constante, a la par que una conciencia legítima de que no se deja de ser hombre por cuidarse.  Cómo citar este artículo: Mendoza-Catalán G, Gallegos-Cabriales EC, Figueroa-Perea JG.

    Introduction. Solo practices have generally been viewed as forming a homogeneous group. However, they may differ on many characteristics. The objective of this paper is to identify different forms of solo practice and to determine the extent to which they are associated with patient experience of care. Methods. Two surveys were carried out in two regions of Quebec in 2010: a telephone survey of 9180 respondents from the general population and a postal survey of 606 primary healthcare (PHC) practices. Data from the two surveys were linked through the respondent's usual source of care. A taxonomy of solo practices was constructed (n = 213), using cluster analysis techniques. Bivariate and multilevel analyses were used to determine the relationship of the taxonomy with patient experience of care. Results. Four models were derived from the taxonomy. Practices in the "resourceful networked" model contrast with those of the "resourceless isolated" model to the extent that the experience of care reported by their patients is more favorable. Conclusion. Solo practice is not a homogeneous group. The four models identified have different organizational features and their patients' experience of care also differs. Some models seem to offer a better organizational potential in the context of current reforms.

    This study aimed to evaluate the feasibility and efficacy of solo-surgeon retroauricular thyroidectomy. For solo-surgery, we used an Endoeye Flex Laparo-Thoraco Videoscope (Olympus America, Inc.). A Vitom Karl Storz holding system (Karl Storz GmbH & Co.) composed of several bars connected by a ball-joint system was used for fixation of endoscope. A snake retractor and a brain-spoon retractor were used on the sternocleidomastoid. Endoscopic thyroidectomy using the solo-surgeon technique was performed in 10 patients having papillary thyroid carcinoma. The mean patient age was 36.0 ± 11.1 years, and all patients were female. There were no postoperative complications such as vocal cord paralysis and hematoma. When compared with the operating times and volume of drainage of a control group of 100 patients who underwent surgery through the conventional retroauricular approach between May 2013 and December 2015, the operating times and volume of drainage were not significantly different (P = .781 and .541, respectively). Solo-surgeon retroauricular thyroidectomy is safe and feasible when performed by a surgeon competent in endoscopic thyroidectomy.

  1. "Ring" in the solo child singing voice.

    Science.gov (United States)

    Howard, David M; Williams, Jenevora; Herbst, Christian T

    2014-03-01

    Listeners often describe the voices of solo child singers as being "pure" or "clear"; these terms would suggest that the voice is not only pleasant but also clearly audible. The audibility or clarity could be attributed to the presence of high-frequency partials in the sound: a "brightness" or "ring." This article aims to investigate spectrally the acoustic nature of this ring phenomenon in children's solo voices, and in particular, relating it to their "nonring" production. Additionally, this is set in the context of establishing to what extent, if any, the spectral characteristics of ring are shared with those of the singer's formant cluster associated with professional adult opera singers in the 2.5-3.5kHz region. A group of child solo singers, acknowledged as outstanding by a singing teacher who specializes in teaching professional child singers, were recorded in a major UK concert hall performing Come unto him, all ye that labour, from the aria He shall feed his flock from The Messiah by GF Handel. Their singing was accompanied by a recording of a piano played through in-ear headphones. Sound pressure recordings were made from well within the critical distance in the hall. The singers were observed to produce notes with and without ring, and these recordings were analyzed in the frequency domain to investigate their spectra. The results indicate that there is evidence to suggest that ring in child solo singers is carried in two areas of the output spectrum: first in the singer's formant cluster region, centered around 4kHz, which is more than 1000Hz higher than what is observed in adults; and second in the region around 7.5-11kHz where a significant strengthening of harmonic presence is observed. A perceptual test has been carried out demonstrating that 94% of 62 listeners label a synthesized version of the calculated overall average ring spectrum for all subjects as having ring when compared with a synthesized version of the calculated overall average nonring

    The El Paso County Geothermal Project at Fort Bliss was an effort to determine the scale and scope of geothermal resources previously identified on Fort Bliss’ McGregor Range in southern Otero County, New Mexico. The project was funded with a $5,000,000 grant to El Paso County from the U.S. Department of Energy (DOE) as part of the American Recovery and Reinvestment Act of 2009 and a $4,812,500 match provided by private sector partners. The project was administered through the DOE Golden Field Office to awardee El Paso County. The primary subcontractor to El Paso County and project Principal Investigator - Ruby Mountain Inc. (RMI) of Salt Lake City, Utah - assembled the project team consisting of Evergreen Clean Energy Management (ECEM) of Provo, Utah, and the Energy & Geoscience Institute at the University of Utah (EGI) in Salt Lake City, UT to complete the final phases of the project. The project formally began in May of 2010 and consisted of two preliminary phases of data collection and evaluation which culminated in the identification of a drilling site for a Resource Confirmation Well on McGregor Range. Well RMI 56-5 was drilled May and June 2013 to a depth of 3,030 ft. below ground level. A string of slotted 7 inch casing was set in 8.75 inch hole on bottom fill at 3,017 ft. to complete the well. The well was drilled using a technique called flooded reverse circulation, which is most common in mineral exploration. This technique produced an exceptionally large and complete cuttings record. An exciting development at the conclusion of drilling was the suspected discovery of a formation that has proven to be of exceptionally high permeability in three desalinization wells six miles to the south. Following drilling and preliminary testing and analysis, the project team has determined that the McGregor Range thermal anomaly is large and can probably support development in the tens of megawatts.

    This paper documents some preliminary results from an evaluation of the costs and benefits to be gained from the integration of wind generated electricity into the El Paso Electric grid system. The study focused on the utilization of the considerable known wind potential of the Guadalupe/Delaware Mountains region, but also looked at other energetic wind resources within 15 miles of El Paso Electric`s Grid. The original project`s goal was to identify the added value of wind in terms of jobs, line support, risk reduction etc., that wind energy could bring to El Paso Electric. Although these goals have not yet been achieved the potential for water savings and reductions in gaseous emissions have been documented. Thus this paper focuses mainly on the water consumption and criteria pollutant emissions that could be avoided by adding wind energy to El Paso Electric`s generation mix. Preliminary data from a renewables attitude survey indicates that, from the 338 respondents, there is overwhelming public support for utilizing such renewable sources of electricity. This case study, which should be of direct relevance to the arid southwestern states and beyond, was sponsored by the Environmental Protection Agency (EPA) and conducted in cooperation with El Paso Electric.

    This report summarizes a number of research efforts completed over the past 20 years in the El Paso del Norte region to characterize pollution sources and air quality trends. The El Paso del Norte region encompasses the cities of El Paso, Texas and Ciudad Juarez, Chihuahua and is representative of many US-Mexico border communities that are facing important air quality issues as population growth and industrialization of Mexican border communities continue. Special attention is given to a group of studies carried out under special US Congressional funding and administered by the US Environmental Protection Agency. Many of these studies were fielded within the last several years to develop a better understanding of air pollution sources and trends in this typical border community. Summary findings from a wide range of studies dealing with such issues as the temporal and spatial distribution of pollutants and pollution potential from both stationary and mobile sources in both cities are presented. Particular emphasis is given to a recent study in El Paso-Ciudad Juarez that focussed on winter season PM{sub 10} pollution in El Paso-Ciudad Juarez. Preliminary estimates from this short-term study reveal that biomass combustion products and crustal material are significant components of winter season PM{sub 10} in this international border community.

    This isostatic residual gravity map is part of an effort to map the three-dimensional distribution of rocks in the central California Coast Ranges and will serve as a basis for modeling the shape of basins and for determining the location and geometry of faults within the Paso Robles quadrangle. Local spatial variations in the Earth\\'s gravity field, after accounting for variations caused by elevation, terrain, and deep crustal structure reflect the distribution of densities in the mid- to upper crust. Densities often can be related to rock type, and abrupt spatial changes in density commonly mark lithological or structural boundaries. High-density rocks exposed within the central Coast Ranges include Mesozoic granitic rocks (exposed northwest of Paso Robles), Jurassic to Cretaceous marine strata of the Great Valley Sequence (exposed primarily northeast of the San Andreas fault), and Mesozoic sedimentary and volcanic rocks of the Franciscan Complex [exposed in the Santa Lucia Range and northeast of the San Andreas fault (SAF) near Parkfield, California]. Alluvial sediments and Tertiary sedimentary rocks are characterized by low densities; however, with increasing depth of burial and age, the densities of these rocks may become indistinguishable from those of older basement rocks.

Detailed geophysical, geochemical, and geological surveys were conducted. The geological and geophysical work delineated the basement highs and trough-like depressions that can exercise control on the occurrence of the thermal waters. The Rinconada fault was also evident. Cross sections drawn from oil well logs show the sediments conforming against these basement highs and filling the depressions. It is along the locations where the sediments meet the basement highs that three natural warm springs in the area occur. Deep circulation of meteoric waters along faults seems to be a reasonable source for the warm water. The Santa Margarita, Pancho Rico, and Paso Robles Formations would be the first permeable zones that abut the faults through which water would enter. Temperatures and interpretation of well logs indicate the warmest aquifer at the base of the Paso Robles Formation. Warm water may be entering higher up in the section, but mixing with water from cooler zones seems to be evident. Geothermometry indicates reservoir temperatures could be as high as 91/sup 0/C (196/sup 0/F).

  13. Del vientre al ΟIΚΟΣ: los pasos femeninos en la Grecia Antigua

    Full Text Available En el presente artículo reflexionaremos sobre una de las transiciones vitales más relevantes para las mujeres griegas: el parto. Protagonizado por dos actores principales, el nonato y la parturienta, el alumbramiento es concebido como una travesía peligrosa que transforma física y socialmente a ambos. Tanto madre como hijo cruzan el umbral del “territorio salvaje” para adentrarse y establecerse en el centro y origen de la vida ciudadana: el οἶκος, asistidos por los dioses Ártemis y Hermes. Estos “dioses pasadores”, facilitan el camino a través de los pasos femeninos que conducen de la oscuridad del cuerpo de la mujer a la luz de la vida en el οἶκος, donde se encuentran con Hestia. De este modo, y a través de las fuentes clásicas y el análisis estructural, indagaremos en el concepto de parto de los griegos, en su carácter de paso y en las deidades “pasadoras” mencionadas.

    Full Text Available En las ciencias sociales se generan debates metodológicos que contribuyen a las formas de comprender la investigación social. En este ensayo se discute el modo de entender el rol del investigador frente a la aproximación y análisis del objeto/sujeto de estudio. El objetivo es cuestionar el uso de la metáfora del investigador como artesano. Esta imagen aparece en los años 50 para explicar la creatividad que requiere el proceso de investigación y análisis cualitativo de datos. Sin embargo, la metáfora del artesano representa una aproximación deductiva del investigador al sujeto/objeto de estudio. Por el contrario, el análisis cualitativo está orientado por procedimientos inductivos. Entonces, se propone la metáfora del cazador tras la presa, como un recurso con consistencia paradigmática y epistemológica que aporta a la comprensión y formación en investigación cualitativa. Within the social sciences, methodological debates contribute to the understanding of social research. This paper discusses one way of understanding the role of the investigator in relation to the approach and analysis of the object/subject of study. The objective is to question the use of the researcher's metaphor as a craftsman. This image appears in the 1950s in order to explain the creativity required by the research process and qualitative data analysis. However, the artisan's metaphor represents a deductive approximation of the researcher to the subject/object of study. On the contrary, the qualitative analysis is oriented by inductive procedures. The metaphor of the hunter after the prey is then proposed as a resource with a paradigmatic and epistemological consistency that contributes to the understanding and training in the qualitative research.

    Affective and cognitive image are two main factors that influence destination in Solo. The purpose of this research is to examine the two main factors of Solo towards tourist attraction. The research method is quantitative. Data collected from observation and survey. A total of 113 respondents obtained from accidental sampling method. The results indicate based on cognitive and affective image. Cognitive consists of culture, batik, city tagline, and community. While, affective consists of tradition, culinary, purposes, climate, and welcoming. The findings show that image has weak correlation towards tourist attraction of Solo. It means most of the tourists are not influenced by city image when they choose Solo as one of their travel destination. The differences between primary and minor image are also examined. Research implication is directed for local government to pursue continuous improvement particularly for the branding of Solo.

    We evaluated the impact of migration to the USA-Mexico border city of El Paso, Texas (USA), parental language preference, and Hispanic ethnicity on childhood asthma to differentiate between its social and environmental determinants. Allergy and asthma prevalence was surveyed among 9797 fourth and fifth grade children enrolled in the El Paso Independent School District. Parents completed a respiratory health questionnaire, in either English or Spanish, and a sub-sample of children received spirometry testing at their school. Here we report asthma and allergy outcomes across ethnicity and El Paso residency duration. Asthma and allergy prevalence increased with longer duration of El Paso residency independent of ethnicity and preferred language. Compared with immigrants who arrived in El Paso after entering first grade (18%), lifelong El Paso residents (68%) had more prevalent allergy (OR, 1.72; 95% CI, 1.32 - 2.24), prevalent asthma (OR, 1.75; 95% CI, 1.24 - 2.46), and current asthma (OR, 2.01; 95% CI, 1.37 - 2.95). Spirometric measurements (FEV1/FVC and FEF25-75) also declined with increasing duration of El Paso residency (0.16% and 0.35% annual reduction, respectively). These findings suggest that a community-wide environmental exposure in El Paso, delayed pulmonary development, or increased health of immigrants may be associated with allergy and asthma development in children raised there.

  19. Offending, Adjudication, and Outcome Patterns of Solo Male, Solo Female, and Partnered Mass Murderers.

    2018-05-01

    Research on mass murder is limited due to differences in definitions (particularly with respect to victim count), as well as categorizations based on motive. These limitations restrict our understanding of the offending, adjudication, and outcome patterns of these offenders and can obscure potential underlying similarities to comparable types of offenders (e.g., lone actors or terrorists). To address some of these limitations, this research study, which includes an international sample of 434 cases (455 total offenders), uses descriptive and empirical analyses of solo male, solo female, and partnered mass murderers (teams of two or more) to explore offending, adjudication, and outcome patterns among these different types offenders. While the results from this research study support much previous mass murder research, the findings also emphasize the importance of large international sample sizes, objective categorizations, and the use of empirically based analyses to further advance our understanding of these offenders.

  20. Geospatial Distribution of Heavy Metals in an Urban Soil, El Paso, Texas, USA

    Some 500 city blocks were selected randomly via population-based stratification. Equal volumes of soil collected from the public space (where present) in front of each house on a block yielded a composite sample. Composites provide neighborhood level "smoothing" relative to sampling many individual houses, and greatly decrease laboratory effort/cost. In the laboratory 10 g of soil were comminuted in a ceramic ball mill, mixed with cellulose/ paraffin binder, and pressed (20 tons) into a pellet. A Panalytical Epsilon5 EDS-XRF, using 8 sequential secondary target conditions and 12 NIST and USGS multi-element rock standards provided analyses. The concentration of Pb ranged from 11 to 420 ppm; Cr, 4.3 - 52 ppm; Cu, 6.5 - 390 ppm; Zn, 17 - 480 ppm; Cd, 0.4 - 12 ppm; and Sb, 2.9 - 20 ppm. High levels of all metals characterize the urban core area of El Paso, which dates to the late 19th Century. This area hosts both commercial and old residential structures, as well as major highways and a large railroad yard. There currently is, and was in the past, considerable light industry in the area. Two highly traveled highway and one railroad border crossing over the Rio Grande into contiguous Cd. Juarez (population close to 2 million) add to current and past contamination. A century-old Pb-Cu-Zn smelter, recently demolished, forms the western boundary of the urban core. Heavy metal pollution from the smelter is recognized near the former site. Its effect on the rest of the urban core is uncertain due to the current and former presence of other heavy metal sources. Aggressive post-World War II growth and expansion of El Paso into the surrounding desert, as is common in the US Southwest, placed newer housing onto more pristine land surfaces. This is reflected in generally low-to-background levels of heavy metals in these newer areas of the city. Thus there is a strong contamination and heavy metals exposure risk gradient between older and newer neighborhoods within a single city

    A phoniatrist analyzes the professional's voice at the beginning of his vocal studies or career but also later, in cases of voice disorder. Phoniatric examination of professional singers must be done according to "all inclusive" protocols of examination. Such protocols must establish the status of basic elements of phonatory system: activator, generator and resonator of voice and articulatory space. All patients requiring phoniatric examination no matter if they are candidates for professional singers, need to provide anamnestic data about their previous problems regarding voice or singing. This examination is necessary and it must include: examination of nose, cavum oris, pharynx, ears and larynx. This analysis is based on evaluation of physiological and pathophysiological manifestations of voice. Determination of musical voice range during phoniatric examination does not intend to make any classification of voice, nor to suggest to vocal teacher what he should count upon from future singers. Musical range can be determined only by a phoniatrist skilled in music or with musical training, but first of all vocal teacher. These methods are used for examination of phonatory function, or laryngeal pathology. They are not invasive and give objective and quantitative information. They include: laryngostroboscopy, spectral analysis of voice (sonography) and fundamental parameters of voice signal (computer program). Articulation is very important for solo singers, because good articulation contributes to qualitative emission of sound and expression of emotions. Tonal-threshold audiometry is performed as a hearing test. They include rhinomanometry, vital capacity measurements, maximal phonation time and phonation quotient. Phoniatric examination is a necessary proceeding which must be performed before admission to the academy of solo singing, and then during singers' education and career. The phoniatric protocol must include a minimal number of parameters, which can be

    Because of the design and specific implantation technique of the stentless Freedom SOLO bioprosthesis, patient selection is crucial. The aim of the study was to discuss the contraindications to this prosthesis based on the authors' implant experience. Between April 2005 and February 2015, one surgeon at the authors' center performed 292 aortic valve replacements using a bioprosthesis, with the initial intention of implanting a SOLO valve in every patient. A search was conducted for all of these patients and data collected on whether a SOLO valve was used, or not. A SOLO valve was implanted in 238 patients (82%), and a stented bioprosthesis in 54 (18%). The predominant reasons not to implant a SOLO valve were asymmetric commissures (26%) and a large aortic annulus (24%). Only one patient had structural valve deterioration, and none of the patients had to undergo reoperation because of aortic valve insufficiency or paravalvular leakage. Asymmetric commissures, large aortic annulus (>27 mm), calcified aortic sinuses, dilated sinotubular junction, aberrant location of coronary ostia and whenever the stent of a stented bioprosthesis is useful, were contraindications to implant a SOLO valve. When these contraindications were taken into account, a very good durability could be achieved with the SOLO valve during mid-term follow up.

    Epithelial tubules, consisting of the epithelial cell sheet with a central lumen, are the basic structure of many organs. Mechanical forces play an important role in epithelial tubulogenesis; however, little is known about the mechanisms controlling the mechanical forces during epithelial tubule morphogenesis. Solo (also known as ARHGEF40) is a RhoA-targeting guanine-nucleotide exchange factor that is involved in mechanical force-induced RhoA activation and stress fiber formation. Solo binds to keratin-8/keratin-18 (K8/K18) filaments, and this interaction plays a crucial role in mechanotransduction. In this study, we examined the roles of Solo and K8/K18 filaments in epithelial tubulogenesis using MDCK cells cultured in 3D collagen gels. Knockdown of either Solo or K18 resulted in rounder tubules with increased lumen size, indicating that Solo and K8/K18 filaments play critical roles in forming the elongated morphology of epithelial tubules. Moreover, knockdown of Solo or K18 decreased the level of diphosphorylated myosin light chain (a marker of contractile force) at the luminal and outer surfaces of tubules, suggesting that Solo and K8/K18 filaments are involved in the generation of the myosin II-mediated contractile force during epithelial tubule morphogenesis. In addition, K18 filaments were normally oriented along the long axis of the tubule, but knockdown of Solo perturbed their orientation. These results suggest that Solo plays crucial roles in forming the elongated morphology of epithelial tubules and in regulating myosin II activity and K18 filament organization during epithelial tubule formation.

    Full Text Available Alfonso Paso was, without doubt, the most prolific of the post-war Spanish playwrights. His numerous theatrical productions, of which there are more than a hundred comedies, led the playwright to a popularity which in turn permitted him to rise within the theatrical hegemony of the time, filling the Spanish stage with an unending series of plays with clear commercial nuances in which the main element is humour. This humour was conceived for the humoristic sensibility of the growing middle class at the end of the fifties and the beginning of the sixties, whose tastes and interests were ideal material for Paso. The unquestionable sociological nuance in Paso’s plays is therefore particularly important since it allows us make a literary study of what Franco’s regime was like, or rather what the society of this regime was like between 1950 and 1971. This article is written with this in mind, and various aspects present in the works of Alfonso Paso are analysed, such as the middle class, the role of women, social changes, and the influence of tourism and immigration in the Spain of that period. | Alfonso Paso fue, sin lugar a dudas, el autor más prolífico de todos los comediógrafos españoles de posguerra. Su extensa producción teatral, compuesta por más de un centenar de comedias, hizo que nuestro dramaturgo alcanzase una fama que le permitió alzarse con la hegemonía teatral del momento, inundando los escenarios españoles con una interminable serie de obras con claros matices comerciales en donde el humor se erige en el verdadero protagonista. Un teatro ideado por y para la sensibilidad humorística de la creciente clase media de finales de los cincuenta y principios de los sesenta, a cuyos gustos e intereses se plegó el dramaturgo. Por este motivo cobra una especial importancia en la obra de Paso su incuestionable matiz sociológico, ya que nos permite emprender el estudio literario de lo que fue el franquismo, o más bien de lo que fue

    Understanding practice behaviors of solo/dual physician ownership and associated factors at the national level is important information for policymakers and clinicians in response to the Affordable Care Act (ACA) of 2010, but poorly understood in the literature. We analyzed nationally representative data (n = 4,720). The study results reveal nearly 33% of the sample reported solo/two-physician practices. Male/minority/older physicians, psychiatrists, favor small practices. Greater market competition was perceived and less charity care was given among solo/two-physician practitioners. The South region was favored by small physician practitioners. Physicians in solo or two-person practices provided fewer services to chronic patients and were dissatisfied with their overall career in medicine. Small practices were favored by international medical graduates (IMGs) and primary care physicians (PCPs). Overall our data suggest that the role of solo/dual physician practices is fading away in the delivery of medicine. Our findings shed light on varied characteristics and practice behaviors of solo/two-physician practitioners, but more research may be needed to reevaluate the potential role of small physician practitioners and find a way to foster a private physician practice model in the context of the newly passed ACA of 2010.

    2011-12-01

    The assessment and characterization of atmospheric aerosols and their optical properties are of great significance for several applications such as air pollution studies, atmospheric visibility, remote sensing of the atmosphere, and impacts on climate change. Decades ago, the interest in atmospheric aerosols was primarily for visibility impairment problems; however, recently interest has intensified with efforts to quantify the optical properties of aerosols, especially because of the uncertainties surrounding the role of aerosols in climate change. The main objective of the optical characterization of aerosols is to understand their properties. These properties are determined by the aerosols' chemical composition, size, shape and concentration. The general purpose of this research was to contribute to a better characterization of the aerosols present in the Paso del Norte Basin. This study permits an alternative approach in the understanding of air pollution for this zone by analyzing the predominant components and their contributions to the local environment. This dissertation work had three primary objectives, in which all three are intertwined by the general purpose of the aerosol characterization in the Paso del Norte region. The first objective was to retrieve the columnar aerosol size distribution for two different cases (clean and polluted scenarios) at each season (spring, summer, fall and winter) of the year 2009. In this project, instruments placed in buildings within the University of Texas at El Paso (UTEP) as well as a monitoring site (CAMS 12) from the Texas Commission on Environmental Quality (TCEQ) provided the measurements that delimited the aerosol size distribution calculated by our model, the Environmental Physics Inverse Reconstruction (EPIRM) model. The purpose of this objective was to provide an alternate method of quantifying and size-allocating aerosols in situ, by using the optical properties of the aerosols and inversely reconstruct and

    To investigate the feasibility and safety of solo surgery with single-port laparoscopic appendectomy, which is termed herein solo-SPLA (solo-single-port laparoscopic appendectomy). This study prospectively collected and retrospectively analyzed data from patients who had undergone either non-solo-SPLA (n = 150) or solo-SPLA (n = 150). Several devices were utilized for complete, skin-to-skin solo-SPSA, including a Lone Star Retractor System and an adjustable mechanical camera holder. Operating times were not significantly different between solo- and non-solo-SPLA (45.0 ± 21.0 minutes vs. 46.7 ± 26.1 minutes, P = 0.646). Most postoperative variables were also comparable between groups, including the necessity for intravenous analgesics (0.7 ± 1.2 ampules [solo-SPLA] vs. 0.9 ± 1.5 ampules [non-solo-SPLA], P = 0.092), time interval to gas passing (1.3 ± 1.0 days vs. 1.4 ± 1.0 days, P = 0.182), and the incidence of postoperative complications (4.0% vs. 8.7%, P = 0.153). Moreover, solo-SPLA effectively lowered the operating cost by reducing surgical personnel expenses. Solo-SPLA economized staff numbers and thus lowered hospital costs without lengthening of operating time. Therefore, solo-SPLA could be considered a safe and feasible alternative to non-solo-SPLA.

    luxR genes encode transcriptional regulators that control acyl homoserine lactone-based quorum sensing (AHL QS) in Gram negative bacteria. On the bacterial chromosome, luxR genes are usually found next or near to a luxI gene encoding the AHL signal synthase. Recently, a number of luxR genes were described that have no luxI genes in their vicinity on the chromosome. These so-called solo luxR genes may either respond to internal AHL signals produced by a non-adjacent luxI in the chromosome, or can respond to exogenous signals. Here we present a survey of solo luxR genes found in complete and draft bacterial genomes in the NCBI databases using HMMs. We found that 2698 of the 3550 luxR genes found are solos, which is an unexpectedly high number even if some of the hits may be false positives. We also found that solo LuxR sequences form distinct clusters that are different from the clusters of LuxR sequences that are part of the known luxR-luxI topological arrangements. We also found a number of cases that we termed twin luxR topologies, in which two adjacent luxR genes were in tandem or divergent orientation. Many of the luxR solo clusters were devoid of the sequence motifs characteristic of AHL binding LuxR proteins so there is room to speculate that the solos may be involved in sensing hitherto unknown signals. It was noted that only some of the LuxR clades are rich in conserved cysteine residues. Molecular modeling suggests that some of the cysteines may be involved in disulfide formation, which makes us speculate that some LuxR proteins, including some of the solos may be involved in redox regulation.

  1. Globalisation, maquiladoras and transnational identities at the US-Mexico border: the case of Ciudad Juarez-El Paso

    Patrick Gun Cuninghame

    2007-05-01

    Full Text Available This paper’s point of departure is that the local and global configurations of identity in Ciudad Juarez, Chihuahua, and in El Paso, Texas, are determined by the processes of economic globalisation, whose main manifestation is or has been until recently the maquiladora assembly plant. Hitherto, studies on border identities have emphasized more socio-cultural processes and have not analysed economic processes sufficiently as decisive in the construction of identities. The paper’s objective is to identify the salient characteristics of the identities of maquiladora workers and ex-workers on both sides of the border and to ascertain if transnational identities are emerging because of the impacts of globalisation, and what impacts these imply for cultural and social policy in “Paso del Norte”.

    Airborne-electromagnetic and earth-resistivity surveys were used to explore for fresh ground water in the Hueco Bolson southeast of El Paso, Texas. Aerial surveys were made along about 500 miles (800 km) of flight line, and 67 resistivity soundings were made along 110 miles (180 km) of profile. The surveys did not indicate the presence of any large bodies of fresh ground water, but several areas may be underlain by small to moderate amounts of fresh to slightly saline water.The material underlying the flood plain of the Rio Grande is predominantly clay or sand of low resistivity. Along a band on the mesa next to and parallel to the flood plain, more resistive material composed partly of deposits of an ancient river channel extends to depths of about 400 to 1,700 feet (120 to 520 m). Locally, the lower part of this more resistive material is saturated with fresh to slightly saline water. The largest body of fresh to slightly saline ground water detected in this study is between Fabens and Tornillo, Texas, mostly in the sandhill area between the flood plain and the mesa. Under assumed conditions, the total amount of water in storage may be as much as 400,000 to 800,000 acre-feet (500 million to 1 billion m ).The resistivity data indicate that the deep artesian zone southwest of Fabens extends from a depth of about 1,200 feet (365 m) to about 2,800 feet (855 m).

    The radiographic and pathologic findings of two Peruvian Paso foals with osteopetrosis are described. Both foals, one male and one female, presented with respiratory difficulty, brachygnathia and failure to rise after birth. Both foals were mildly anemic, hypogammaglobulinemic and had elevations in serum alkaline phosphatase. Increased medullary bone opacity was noted on radiographs of the extremities, spine and skull in both foals. A lack of normal cortical:medullary bone distinction was evident radiographically. The medullary primary spongiosa appeared to run in parallel columns away from the physes of all long bones and the vertebrae. This created a distinctive hour glass appearance to the osteopetrotic bones. One foal developed a bacterial pneumonia. Both foals were euthanized due to failure to thrive. Histopathology and electron microscopy documented these foals to have normal osteoclastic numbers but lack normal ruffled borders, lack of a clear zone and normal lysosomal numbers indicative of cellular dysfunction. These clinical, radiographic and pathologic findings are similar to the juvenile, lethal autosomal recessive form of osteopetrosis described in humans. Osteopetrosis has not been previously described in a female foal

    The University of Texas at El Paso (UTEP) is located on 300 acres, only a few hundred years from the US/Mexico border. The DOE Infrastructure Support Program was initiated at UTEP in 1987. The purpose of the program was to assist the University in building the infrastructure required for its emerging role as a regional center for energy-related research. Equally important was the need to strength the University`s ability to complete for sponsored energy-related programs at the state and national levels and to provide opportunities for faculty, staff and students to participate in energy-related research and outreach activities. The program had four major objectives, as follows: (1) implement energy research, outreach and demonstration projects already funded, and prepare new proposals to fund university research interests; (2) establish an Energy Center as a separate operational entity to provide continuing infrastructure support for energy-related programs; (3) strengthen university/private sector energy research linkages; and (4) involve minority graduate and undergraduate students in energy research and outreach activities. Each of the above objectives has been exceeded substantially, and, as a consequence, the University has become a regional leader in energy and environmental research and outreach efforts.

    Full Text Available Objetivo. Este estudio analizó el fenómeno de la accidentalidad laboral en un grupo de 10 trabajadores de una empresa productora de papel, cuyas acciones conllevaron a un accidente incapacitante. Método. Se utilizó una entrevista semi-estructurada y se analizó la información siguiendo el enfoque cualitativo de tipo constructivo-interpretativo. El análisis comprensivo de las entrevistas permitió identificar que, aunque en la empresa se siguieran los lineamientos del Sistema General de Riesgos Profesionales en Colombia, los trabajadores accidentados tuvieran el conocimiento completo de los riesgos y el deseo de protegerse, no lograron articular estos aspectos para dirigir sus acciones en el momento de la situación de riesgo. Resultados. Se evidenció que el problema se ubica en el nivel de la conciencia de sí mismo como valor de vida y no en el de la cognición como conocimiento o información. Aunque este es necesario, no es suficiente para mantener la protección total. Se concluye que ser consciente del riesgo no es lo mismo que saber sobre la existencia de riesgos o preocuparse por sus consecuencias para el bienestar personal; es algo que se sitúa ustamente en el momento concreto y presente en el que el trabajador debe pensarse a sí mismo para actuar, manteniendo viva y presente la necesidad de salvaguardar su integridad física. Conclusión. Los resultados pueden ser considerados en los planes de protección empresarial para favorecer en los trabajadores una mejor visión y comprensión de sí mismos frente a su protección y cuidado.

    The purpose of this descriptive report is to provide the first representative information on the sociodemographic profile and the prevalence of mental and physical health conditions of two "at-risk" groups of Latino caregivers: solo grandparent caregivers and single parents. The 2012 Behavior Risk Factor Surveillance System was used to compare five dimensions of health on a sample of Latino solo grandparents and Latino single parents, raising their grandchildren/children alone. Bivariate and logistic regression comparative analyses were conducted on study measures. Latino solo grandparents have a high prevalence of chronic health conditions, including arthritis (51%), depression (40%), diabetes (34%), and asthma (34%). Latino single parents have lower but troubling health risks, including depression (22%), diabetes (14%), and asthma (14%). Differences between the two groups were largely due to the grandparents older age. Latino solo grandparents have a high prevalence of several chronic medical conditions. The prevalence of disorders is much lower for Latino single parents, although they too have disturbing health risks. Latino solo grandparents perform their parenting role under intense physical and emotional strain. Health professionals can be instrumental in facilitating interventions that affect the well-being of this expanding family group.

    Full Text Available National Road no. 42 runs along one of the shores of the river Rhine in the neighbourhood of Rhöndorf. It is crossed by a secondary road by means of an elevated crossing, which can carry light vehicles and pedestrians. The crossing is 136.5 m in length, and consists of five spans, whose lengths are 23.6, 32.1, 32.1, 28.7 and 20 m. The width of the deck is 5.5 m, of which 4 m are taken up with the road pavement, and the rest with two lateral footpaths. The structure is a boxgirder. It is a prestressed, continuous beam, which runs along a curve. Access to the bridge is along ramps built on soil embankments. Owing to the curved planform of the crossing, the torsion forces on the structure are relatively important, but the special distributions of the prestressing cables has made it possible to counteract this loading effect in a satisfactory manner. The hollow reinforced concrete supports are trapezoidal in cross-section, and have hinges at the top and 1 bottom. Thus they act as pendules. The tubes containing the prestressing cables are injected with cement after the cables have been stretched, in accordance with the technique of the contractors, Messrs. Polensky & Zöllner; a firm of worldwide reputation.La carretera nacional número 42 se extiende a lo largo de una de las márgenes del río Rin, en las inmediaciones de Rhöndorf; el cruce con un camino secundario se salva mediante un paso superior, para vehículos ligeros y peatones, que tiene 136,5 m de longitud total, subdividida en cinco tramos de 23,6; 32,1; 32,1; 28,7, y 20 m de luz, respectivamente. La anchura del tablero es de 5,5 m, de los que 4 m corresponden a la calzada y 1,50 a dos andenes laterales e iguales. La estructura resistente es una viga-cajón, continua, pretensada, cuyo eje tiene forma de U muy aplanada. Los accesos al paso están constituidos por dos rampas apoyadas sobre terraplenes.

    In 1978 a sample of 158 solo mothers was interviewed by third year psychology students under the supervision of the author to obtain data both on their child rearing practices (for comparison with data obtained the year before from a sample of dual parents) and on their social circumstances. These data indicate that in the case of women who had previously been married, most aspects of their life, with the exception of finance, are now improved. Freedom from conflict and greater independence are cited as the advantages of being a solo parent; loneliness and responsibility are the major disadvantages. Parents and friends are the chief sources of support.

    We examined the major causes of and risk factors for death among migrants who died while making unauthorized border crossings into the United States from Mexico. Decedents were included in the study if (1) their remains were found between January 1, 2002, and December 31, 2003, in any US county along the 650-mi (1040-km) section of the US-Mexican border from Yuma, Ariz, to El Paso, Tex; (2) their immigration status was unauthorized; and (3) they were believed to have died during transit from Mexico to the United States. Characteristics of the decedents and causes of and risk factors for their deaths were examined. Among the 409 decedents meeting our inclusion criteria, environmental heat exposure (n=250; 61.1%) was the leading cause of death, followed by vehicle crashes (n=33; 8.1%) and drownings (n=24; 5.9%). Male decedents (n= 298; 72.8%) outnumbered female decedents (n = 105; 25.6%) nearly 3 to 1. More than half of the decedents were known to be Mexican nationals (n=235; 57.5%) and were aged 20 to 39 years (n=213; 52.0%); the nationality of 148 (36.2%) decedents was undetermined. Deaths among migrants making unauthorized crossings of the US-Mexican border are due to causes that are largely preventable. Prevention strategies should target young Mexican men, and focus on preventing them from conceiving plans to cross the border, discouraging them from using dangerous routes as crossing points, and providing search-and-rescue teams to locate lost or injured migrant crossers.

    2012-05-01

    To compare demographics and motivations for falls from bridges at the United States-Mexico border and in El Paso County, Texas, and to analyze injuries and injury patterns to support intentionality and to provide treatment recommendations. A retrospective observational review was conducted of hospital admissions to a trauma center after falls from bridges from 1995 to 2009. Statistical methods used were chi-square testing, T-test for means comparison, univariate correlations, and regression analysis. Of the 97 evaluated patients, 81.4% fell from U.S.-Mexico border bridges, including one patient who fell from a railway bridge; 74.7% of those falling from border bridges had a non-U.S. address, contrasting with 22.2% of those who fell within the United States. Falls over the border were associated with more immigration-related motivations and fewer suicide attempts. Injuries included lower extremities in 76 (78.4%) and thoracolumbar spine in 27 (27.8%) patients; 16 patients with a thoracolumbar spine fracture (59.3%) also had a lower extremity injury. Mean hospital length of stay was 7.2 days. Mean injury severity score was 8.45 (range 1-43). Age, injury severity score, and pelvic fracture increased the hospital length of stay. Patients fell while emigrating-immigrating based on residence and motivating factors. A dyad of lower extremity and thoracolumbar spine injuries coincided in 59.3% of those with a thoracolumbar spine injury; thoracolumbar spine imaging of patients evaluated after falls from bridges is recommended. Proposed prevention strategies include posting signs on bridges and installing catch-net safety barriers.

Se realizaron entrevistas a 18 actores y se desarrollaron seis grupos focales. Para el análisis de datos, se usó el Atlas ti®, el acuerdo entre jueces y el análisis de las narrativas. Resultados. La rehabilitación integral es percibida de distintas maneras por los actores, entre las que priman tres concepciones de ella: como resultado de un proceso de rehabilitación funcional, como derecho y como garante de inclusión social. Conclusiones. Mientras exista diversidad y dispersión acerca de la rehabilitación integral, será difícil concebir, implementar, evaluar y participar activamente en dicho proceso. En consecuencia, las barreras de acceso a ella se incrementarán y estará lejos de entenderse como un derecho que se ejerce desde una visión integral de ser humano. Dicho esto, se enuncian implicaciones para la academia, los prestadores de servicios y las políticas públicas.

  20. El uso de Internet y las actitudes políticas: Datos cuantitativos y cualitativos de España

    Full Text Available In this paper we argue that the widespread use of new technologies may contribute to a change in political attitudes in democracies in industrialized developed countries. The interactivity and cross-cutting nature of new technologies means they allow easier access to information. This can stimulate interest, encourage a sense of political effectiveness, and a preference for direct democracy. This hypothesis is evaluated using original qualitative and quantitative data collected in Spain. Data drawn from a study on the Internet and political participation are used in conjunction with data from a qualitative study of two focus groups comprising young middle-class citizens, segmented by their level of Internet use. We find Internet users to be clearly more interested in politics and to display higher levels of internal efficacy than nonusers, even after controlling for a variety of sociodemographic and attitudinal factors. The focus groups provided insights into the mechanisms underlying the differences detected between Internet users and nonusers.

    Full Text Available A integração lavoura-pecuária é uma alternativa de renda dos produtores no sul do Brasil. Entretanto, o pisoteio animal e, ou, o preparo de solo podem compactá-lo, prejudicando o crescimento radicular e a produtividade das plantas. Estudaram-se os efeitos do pisoteio animal em regime de pastejo contínuo durante o inverno/primavera e do impacto do plantio direto e do preparo convencional de solo no estado de compactação, atributos químicos e distribuição radicular. Em Podzólico Vermelho-Amarelo de textura superficial franca, foi implantada uma pastagem de estação fria composta por aveia (Avena strigosa Schreb e azevém (Lolium multiflorum L.. A carga animal variou conforme o crescimento da pastagem. Em dezembro de 1996, foi implantada a cultura do milho (Zea mays L. para a produção de silagem, usando os seguintes tratamentos: plantio direto na área não pastejada, plantio direto após o pastejo, preparo convencional de solo na área não pastejada e preparo convencional de solo após pastejo. As avaliações apresentadas neste estudo são referentes ao terceiro ano de cultivo, no qual houve um período de pastejo de 107 dias. Aos 45 dias da emergência do milho, foram abertas trincheiras (100 x 40 cm para visualizar a distribuição do sistema radicular e coletar amostras de solo, a cada 5 cm, para caracterização química e determinação da densidade do solo e de raízes. Ao longo do perfil (0-40 cm, o desenho da distribuição de raízes indicou maior quantidade de raízes no preparo convencional de solo, concordando com os resultados de densidade de raízes. O pisoteio animal não teve efeito sobre as características físicas, possivelmente pelo fato de o resíduo da pastagem permanecer próximo a 1,0 Mg ha-1 de matéria seca. A densidade do solo no plantio direto, na camada de 5-10 cm, foi de 1,41 Mg m-3, tanto na área pastejada como na não pastejada. No preparo convencional de solo, esses valores foram de 1,15 Mg m-3

  7. Economic impact of dental hygienists on solo dental practices.

    Science.gov (United States)

    Lazar, Vickie F; Guay, Albert H; Beazoglou, Tryfon J

    2012-08-01

    The fact that a significant percentage of dentists employ dental hygienists raises an important question: Are dental practices that utilize a dental hygienist structurally and operationally different from practices that do not? This article explores differences among dental practices that operate with and without dental hygienists. Using data from the American Dental Association's 2003 Survey of Dental Practice, a random sample survey of U.S. dentists, descriptive statistics were used to compare selected characteristics of solo general practitioners with and without dental hygienists. Multivariate regression analysis was used to estimate the effect of dental hygienists on the gross billings and net incomes of solo general practitioners. Differences in practice characteristics--such as hours spent in the practice and hours spent treating patients, wait time for a recall visit, number of operatories, square feet of office space, net income, and gross billings--were found between solo general practitioners who had dental hygienists and those who did not. Solo general practitioners with dental hygienists had higher gross billings. Higher gross billings would be expected, as would higher expenses. However, net incomes of those with dental hygienists were also higher. In contrast, the mean waiting time for a recall visit was higher among dentists who employed dental hygienists. Depending on personal preferences, availability of qualified personnel, etc., dentists who do not employ dental hygienists but have been contemplating that path may want to further research the benefits and opportunities that may be realized.

  8. "Telling a Story." On the Dramaturgy of Monophonic Jazz Solos

    2016-07-01

    Full Text Available The metaphor of storytelling is widespread among jazz performers and jazz researchers. However, little is known about the precise meaning of this metaphor on an analytical level. The present paper attempts to shed light on the connected semantic field of the metaphor and relate it to its musical basis by investigating time courses of selected musical elements and features in monophonic jazz improvisations. Three explorative studies are carried out using transcriptions of 299 monophonic jazz solos from the Weimar Jazz Database. The first study inspects overall trends using fits of quadratic polynomials onto loudness and pitch curves. The second study does the same using selected features related to intensity, tension and variability over the course of phrases in the solos. The third study examines the distribution of the relative positions of various improvisational ideas in a subset of 116 solos. Results show that certain trends can be found, but not to a large extent. Significant trends most often display arch-shaped curves as expected from classical dramatic models. This is also in accordance with the fact that expressive improvisational ideas are more often found in the last part of a solo, while more relaxed ideas occur earlier. All in all, jazz improvisations show a wide range of variation and no single overarching dramatic model could be identified.

    Full Text Available Indonesia's modern consumer societies develop in conjunction with the history of global economy and the transformation of consumer capitalism. This happens in many communities in cities of Indonesia, including Solo. With a population of 500 thousand at night and 1.5 million during the day, it is a potential market for global products. Therefore, it is obvious if the Solo people's tastes are no different than other communities, because of the consumer behaviour and global economy that are intertwined. The value of the meaning of products have also shifted, such as with cars. Cars that usually function as a vehicle no different than a wagon, have changed into a symbol of social class for the modern society, even for the people of Solo. The functions and facilities of the Various brands and types of cars, and elements that are related to automotive technology, are not too different. What makes the difference between these cars lays on the design of the form and image. This form design is able to create an image for certain social class for its user and its product brand. The most interesting phenomenon from automotive products in Indonesia is what happened with Toyota Kijang. Since its launch on 1977, Toyota Kijang, which is on its fifth generation this year, has succeeded in becoming the number one choice for cars for Indonesians.

  19. Fail or flourish? Cognitive appraisal moderates the effect of solo status on performance.

    Science.gov (United States)

    White, Judith B

    2008-09-01

    When everyone in a group shares a common social identity except one individual, the one who is different from the majority has solo status. Solo status increases one's visibility and performance pressure, which may result in stress. Stress has divergent effects on performance, and individuals' response to stressful situations is predicted by their cognitive appraisal (challenge or threat) of the situation. Two experiments test the hypothesis that cognitive appraisal moderates the effect of solo status on performance. Experiment 1 finds that at relatively high appraisal levels (resources exceed demands), solo status improves men's and women's performance; at relatively low appraisal levels, solo status hurts performance. Experiment 2 replicates this effect for solo status based on minimal group assignment. Results suggest that for individuals who feel challenged and not threatened by their work, it may help to be a solo.

    2009-12-01

    Guatemala is a country severely affected by malnutrition, particularly in its child population. The present study aimed to assess the impact of recognised aetiological factors on the prevalence of malnutrition and to establish the efficacy of a Guatemalan malnutrition clinic by examining the changes in the prevalence of malnutrition in the ten surrounding communities served by the clinic. Records of children (n 7681) aged 5-16 years seen by the clinic between 2004 and 2006 were examined. Anthropometric data for each child were taken from these records and used as an indicator for their nutritional status to estimate the change in rates of malnutrition during this period. An overall reduction was seen in all forms of malnutrition over the 3-year period, although over 50 % of the study population remained malnourished in 2006. A consistent reduction was also seen in rates of moderate and severe malnutrition, but not in rates of mild malnutrition. The results demonstrate that clinics such as Primeros Pasos can have a beneficial effect on schoolchildren, particularly those who are severely malnourished. A need has been highlighted for more research in this area, particularly how clinics such as Primeros Pasos can be best used in the fight against malnutrition.

    2017-07-03

    little sister: An Afro-Temporal Solo-Play is at once a memory-scape and a mytho-biography set to poetry, movement, and mixed media. A performance poem spanning from the Antebellum South to present-moment Chicago, it tells the story of a nomadic spirit named little-she who shape-shifts through the memories and imaginings of her sister, the narrator. Through the characters little-she and the narrator, the solo-performance explores embodied ways to rupture and relieve the impact of macro forms of violence in the micro realm of the everyday. To this end, little sister witnesses and disrupts the legacy of violence in the lives of queer Black women through a trans-temporal navigation of everyday encounters within familial, small groups and intimate partner spaces.

  9. Interplay between Solo and keratin filaments is crucial for mechanical force–induced stress fiber reinforcement

    2016-01-01

    Mechanical force–induced cytoskeletal reorganization is essential for cell and tissue remodeling and homeostasis; however, the underlying cellular mechanisms remain elusive. Solo (ARHGEF40) is a RhoA-targeting guanine nucleotide exchange factor (GEF) involved in cyclical stretch–induced human endothelial cell reorientation and convergent extension cell movement in zebrafish gastrula. In this study, we show that Solo binds to keratin-8/keratin-18 (K8/K18) intermediate filaments through multiple sites. Solo overexpression promotes the formation of thick actin stress fibers and keratin bundles, whereas knockdown of Solo, expression of a GEF-inactive mutant of Solo, or inhibition of ROCK suppresses stress fiber formation and leads to disorganized keratin networks, indicating that the Solo-RhoA-ROCK pathway serves to precisely organize keratin networks, as well as to promote stress fibers. Of importance, knockdown of Solo or K18 or overexpression of GEF-inactive or deletion mutants of Solo suppresses tensile force–induced stress fiber reinforcement. Furthermore, knockdown of Solo or K18 suppresses tensile force-induced RhoA activation. These results strongly suggest that the interplay between Solo and K8/K18 filaments plays a crucial role in tensile force–induced RhoA activation and consequent actin cytoskeletal reinforcement.

Com este trabalho objetivou-se investigar o efeito de três sistemas de preparo do solo na FCO2, temperatura e umidade do solo em área de reforma da cultura de cana-de-açúcar. A área experimental foi constituída de três parcelas, cada uma recebendo um dos preparos do solo: preparo convencional (PC, subsolagem convencional (SC e subsolagem localizada (SL. A FCO2, temperatura e a umidade do solo foram avaliadas durante o período total de 17 dias. A FCO2 foi maior no preparo PC (0,75 g CO2 m-2 h-1. A temperatura do solo não diferiu (p > 0,05 entre as subsolagens: SL (26,2 ºC e SC (25,9 ºC. A umidade do solo foi maior na SL (24%, seguida pela SC (21,8% e preparo PC (18,3%. Apenas no preparo PC foi observada correlação significativa (r = –0,71; p < 0,05 entre FCO2 e a temperatura do solo. O preparo PC apresentou emissão total (2.864,3 kg CO2 ha-1, superior às emissões nas subsolagens: SC (1.970,9 kg CO2 ha-1 e SL (1.707,7 kg CO2 ha-1. A conversão do sistema de preparo PC para a SL diminuiu as emissões de CO2 do solo, reduzindo a contribuição da agricultura para o aumento dos gases de efeito estufa na atmosfera.

    2014-12-01

    InTeGrate (Interdisciplinary Teaching about Earth for a Sustainable Future) has developed teaching modules that focus on Earth sustainability and Earth-centered societal issues. We have begun to implement modules on climate change, earth materials and freshwater into introductory geology and environmental science courses taught at the University of Texas at El Paso (UTEP), El Paso Community College (EPCC) and local early college high schools (ECHS) for classes of 20 to 220 students. Our eventual goal is to insure students taking introductory classes at any institution will be exposed to comparable content and be similarly prepared for advanced courses. Our initial results suggest that the modules' use of case studies and analysis of authentic data sets are very appealing to our student body (over 70% Hispanic). Since many students do not speak English at home, they were challenged by vocabulary presented in some modules. Modules containing glossaries and extensive background material (such as concept maps and annotated figures) proved very helpful to these students. The use of pre-activity quizzes insured that the students had mastered basic concepts needed for in-class activities. Modifications required to teach these modules in larger classes included condensing materials and reducing the amount of color figures to save paper and printer costs, streamlining dissemination/collection of in-class group assignments, and adapting assignments such as jigsaws and gallery walks to the confines of a large lecture hall with fixed seating. Student reflections indicated students were able to make connections to societal issues and retain these ideas through the end of the courses.

    2016-06-01

    Full Text Available Resumo Este artigo analisou o albedo do solosolo abaixo do dossel considerando duas etapas no ciclo hidrológico, a primeira em que o solo estava inundado e a segunda em que o solo estava coberto por serrapilheira acumulada sobre o solo em área inundável de Vochysia divergens Pohl no Pantanal, Brasil. Os valores de αsolo foram calculados pela relação entre as radiação solar global refletida e a incidente medidas abaixo do dossel por meio de estações meteorológicas. A inundação da área ocorreu durante fevereiro a junho e posteriormente houve um aumento gradativo de serrapilheira acumulada sobre o solo. O αsolo variou sazonalmente com maiores valores durante o período seco em que houve um aumento de aproximadamente 42% do αsolo em relação ao período com inundação. Análises de correlação cruzada entre o αsolo e precipitação, umidade do solo e a serrapilheira acumulada sobre o solo explicam em parte a influência direta e/ou indireta sobre o αsolo. A precipitação não influenciou diretamente sobre o αsolo do mês atual, enquanto que a umidade do solo influenciou diretamente sobre o αsolo no mês atual e nos seguintes meses, e a serrapilheira acumulada do solo correlacionou-se positivamente com o αsolo indicando influência direta no mês atual.

    Full Text Available A degradação do solo no semiárido também ocorre pelo desmatamento da Caatinga e pela remoção da camada superficial do solo, cujo destino é a indústria de cerâmica ou olarias. O presente trabalho objetivou avaliar o crescimento da mamoneira em solos degradados. Os tratamentos consistiram de solos degradados: subsolo degradado-1, subsolo degradado-2 e área desmatada; quatro doses de fósforo (0, 100, 200, 300 mgkg-1 P, com três repetições. As testemunhas absolutas, sem fósforo, corresponderam ao solo salinizado não corrigido, solo-1 não degradado, solo-2 não degradado e solo de caatinga não desmatada. O solo degradado por sais, o subsolo-2, recebeu correção com gesso agrícola, foi incubado e lavado. Os resultados demonstraram que a análise do subsolo degradado revelou alta salinidade e baixos teores de fósforo e matéria orgânica, o subsolo degradado salino exige correção com gesso para tornar possível o cultivo da mamona em caatinga desmatada e subsolos degradados. As doses de fósforo não promoveram desenvolvimento significativo em mudas de mamona.

    Full Text Available O morangueiro é uma cultura importante em vários países, principalmente nos Estados Unidos e na Europa, por suas características sensoriais, propriedades nutritivas e por sua rentabilidade. O cultivo comercial sem solo de morangueiro está bem desenvolvido na Europa, onde tem permitido um aumento da produtividade e qualidade da produção assim como a ampliação da oferta do produto ao longo do ano. Predomina o sistema aberto, em sacolas ou vasos com diferentes tipos de substratos, utilizando-se densidades de 8 a 12plantas m-2. As produtividades obtidas estão entre 5 e 10kg m-2. Para isolar as plantas do solo e facilitar o manejo da cultura, os vasos ou sacolas são suspensos a uma altura entre 0,8 e 1m da superfície do solo. A composição da solução nutritiva é variável, refletindo as diferentes condições produtivas. As mudas são produzidas principalmente em bandejas com substrato, a partir de pontas de estolões obtidas da multiplicação de plantas matrizes provenientes da propagação in vitro. No Brasil, o cultivo sem solo de morangueiro é ainda incipiente e os resultados produtivos e econômicos têm sido insatisfatórios, principalmente por falta de informações de pesquisas capazes de indicar sistemas apropriados de cultivo para as condições locais. É necessário desenvolver sistemas sustentáveis, preferencialmente fechados, combinando alta produtividade e elevada eficiência de utilização da água e dos nutrientes. No presente trabalho, são revisados os principais aspectos da produção em sistemas de cultivo sem solo de mudas e fruta de morangueiro. São descritos a produção de mudas, os sistemas e as soluções nutritivas empregadas em diferentes países. Ao final, são feitas inferências sobre a possibilidade de adoção e geração do sistema de cultivo sem solo apropriado para as condições brasileiras.Strawberry is a very important crop in Europe and USA due to its nutritional and sensorial

Soil seed bank is the reservoir of viable seeds or of vegetative propagules that are present in the soil and that are able to recompose a natural vegetation. In the agroecossystems the soil seed bank is related to weeds, and the knowledge of its size and composition in terms of species can be used in the prediction of future infestations, to built simulation models of population establishment through time and also the definition of soil and cultural management programs, in order to have a rational use of herbicides.O objetivo desta revisão é discorrer sobre alguns pontos importantes no estudo do banco de sementes no solo, desde as sua características até aspectos metodológicos para sua determinação. Denomina-se de banco de sementes a reserva destas ou de propágulos vegetativos viáveis presentes no solo e que são capazes de recompor uma vegetação. Nos sistemas agrícolas o banco está relacionado com o estudo das plantas daninhas; o conhecimento do seu tamanho e das espécies que o compõem poderá ser utilizado na previsão de infestações futuras, na construção de modelos de estabelecimentos populacionais no tempo e consequentemente na definição de programas de manejo de solo e culturais, visando racionalizar a utilização de herbicidas.

    Full Text Available A análise ambiental, com base nos processos de morfogênese e pedogênese, possibilita informações importantes para a elaboração de políticas públicas visando o uso e ocupação da paisagem de maneira sustentável. Com isso, objetivou-se identificar os diferentes níveis de vulnerabilidade natural à perda de solo do município de Silveira Martins, RS. Foi elaborado um banco de dados espaciais em um ambiente de Sistemas de Informações Geográficas (SIG com auxílio do software Spring. O zoneamento da vulnerabilidade natural à perda de solo foi elaborado com base nas informações referentes à declividade, geomorfologia, geologia e solos de acordo com o grau de vulnerabilidade de cada informação, por meio da álgebra de mapas. Para o território municipal de Silveira Martins identificou-se a ocorrência de cinco classes. Destacam-se as unidades estáveis com predomínio dos processos formadores do solo (38,08% da área municipal, e as unidades moderadamente vulneráveis, prevalecendo os processos erosivos (53,67%. As áreas classificadas como moderadamente vulnerável e vulnerável (8,25%, correspondem a áreas com inclinações superiores a 25º e com formação geológica e geomorfológica menos estáveis. Nas unidades em que predominou a vulnerabilidade natural, sugere-se especial atenção em relação ao meio natural e aos agentes que o influenciam, visando boas práticas sociais associadas às políticas ambientais no processo de tomada de decisões econômicas, possibilitando a valorização e proteção do meio natural.

    2018-02-01

    Dynamic urbanization in Solo Raya, a local term for Surakarta Metropolitan, amongst rapid regional based-urbanization in Indonesia, shows the unbalance pattern of growth. A number of Surakarta City’s peripherals become the newly growing area which is characterized by a well-facilitated region, while the former urbanized areas next to the city center present the declining process. Different socioeconomic development triggers a unique mosaic of socio-spatial pattern, on which the phenomena of peripheralization could be investigated. Urban investment that boosted by the political will of both the national and local government has led to a shift in demographic condition. A relatively massive in-migration has been attracted to the peripheral and creates the new landscape of urban-rural society. Complex dynamic of metropolitan growth and the resulting peripheralization reminds that socio-spatial pattern calls the challenges for managing the rapid change of land use and space use. The pattern of urbanization that differs upon the surrounding areas of Surakarta City would be interesting to be explored. This paper will discuss the conceptual framework of peripheral urbanization and the methodological approach. It is actually the part of ongoing research on peripheralisation in Solo Raya.

    The incidence of postoperative thrombocytopenia after aortic valve replacement with the Freedom Solo bioprosthesis remains unclear. This propensity-matched study was carried out to evaluate the incidence and clinical impact of thrombocytopenia in patients receiving the Freedom Solo bioprosthesis. Patients who underwent aortic valve replacement with a Freedom Solo or Carpentier-Edwards Perimount pericardial prosthesis at our institution between 2006 and 2008 were screened retrospectively. Exclusion criteria included double valve replacement, redo surgery, and active endocarditis. Two hundred six patients were considered eligible for this analysis. Using propensity scores 36 matched pairs of patients with a Freedom Solo or Perimount bioprosthesis were obtained. The primary end point was the occurrence of postoperative thrombocytopenia. Secondary end points were postoperative thromboembolic or hemorrhagic events and 30-day mortality. Before matching, severe thrombocytopenia (Solo bioprosthesis and 1% with a Perimount bioprosthesis (p Solo (p Solo and Perimount bioprostheses, respectively (p Solo implantation.

    Full Text Available Os solos do Estado da Paraíba apresentam grande diversidade de características químicas, físicas e mineralógicas, acarretando em variações nos teores e formas de K disponíveis no solo. Objetivou-se com este trabalho avaliar os teores de K não-trocável, K trocável e K solúvel em doze solos do Estado da Paraíba, na ausência e na presença de fertilização potássica, e correlacioná-los com as características químicas, físicas e mineralógicas desses solos. O estudo constou de 60 tratamentos, sendo 12 solos e cinco doses de K (0; 50; 100; 200 e 300 mg dm-3 na forma de cloreto de potássio, com três repetições. Após receberem os tratamentos, os solos foram incubados por um período de 21 dias, e em seguida, uma sub-amostra de 0,2 dm³ de cada solo foi retirada para determinação dos teores de K não-trocável, K trocável e K solúvel. Os solos formados sob clima semiárido foram os solos que apresentaram as maiores reservas de K não-trocável. Solos com maior proporção de mica e minerais do tipo 2:1 na fração argila apresentaram os maiores teores de K não-trocável e K trocável. Independente do grupo de solos, os teores de silte apresentaram correlação elevada com os teores de K não-trocável e de K trocável. Nos solos mais desenvolvidos, não foi evidenciada fixação de K proveniente do fertilizante. Porém, nos solos menos desenvolvidos, a fixação de K ficou evidenciada pela pequena quantidade de K recuperada pelo extrator acetato de amônio nos solos mais argilosos e, principalmente, naqueles com predominância de minerais do tipo 2:1 e mica.

    2017-04-01

    The objective of this study is to document the health profile of 252 African-American grandparents raising their grandchildren solo, compared with 1552 African-American single parents. The 2012 Behavior Risk Factor Surveillance System is used to compare the specific physical and mental health profiles of these two family groups. The findings suggest solo grandparents have prevalence of many health conditions, including arthritis (50.3 %), diabetes (20.1 %), heart attack (16.6 %) and coronary heart disease (16.6 %). Logistic regression analyses suggest that solo grandparents have much higher odds of several chronic health disorders in comparison with single parents, but this difference is largely explained by age. Although solo grandparents have good access to health care insurance and primary care providers, a substantial percentage (44 %) rate their health as fair or poor. Practice interventions to address African American solo grandparents' health needs are discussed.

  1. Interplay between Solo and keratin filaments is crucial for mechanical force-induced stress fiber reinforcement.

    Mechanical force-induced cytoskeletal reorganization is essential for cell and tissue remodeling and homeostasis; however, the underlying cellular mechanisms remain elusive. Solo (ARHGEF40) is a RhoA-targeting guanine nucleotide exchange factor (GEF) involved in cyclical stretch-induced human endothelial cell reorientation and convergent extension cell movement in zebrafish gastrula. In this study, we show that Solo binds to keratin-8/keratin-18 (K8/K18) intermediate filaments through multiple sites. Solo overexpression promotes the formation of thick actin stress fibers and keratin bundles, whereas knockdown of Solo, expression of a GEF-inactive mutant of Solo, or inhibition of ROCK suppresses stress fiber formation and leads to disorganized keratin networks, indicating that the Solo-RhoA-ROCK pathway serves to precisely organize keratin networks, as well as to promote stress fibers. Of importance, knockdown of Solo or K18 or overexpression of GEF-inactive or deletion mutants of Solo suppresses tensile force-induced stress fiber reinforcement. Furthermore, knockdown of Solo or K18 suppresses tensile force-induced RhoA activation. These results strongly suggest that the interplay between Solo and K8/K18 filaments plays a crucial role in tensile force-induced RhoA activation and consequent actin cytoskeletal reinforcement. © 2016 Fujiwara et al.

A total of 10,888 family physicians seeking certification through the American Board of Family Medicine in 2013 completed a demographic survey. Their practices were split into categories by size: solo, small (2 to 5 providers), medium (6 to 20 providers), and large (more than 20 providers). We also determined the rurality of the county where the physicians practiced. We developed 2 logistic regression models: one assessed predictors of practicing in a solo or small practice, while the other was restricted to solo and small practices and assessed predictors of practicing in a solo practice. More than one-half of respondents worked in solo or small practices. Small practices were the largest group (36%) and were the most likely to be located in a rural setting (20%). The likelihood of having a care coordinator and medical home certification increased with practice size. Physicians were more likely to be practicing in small or solo practices (vs medium-sized or large ones) if they were African American or Hispanic, had been working for more than 30 years, and worked in rural areas. Physicians were more likely to be practicing in small practices (vs solo ones) if they worked in highly rural areas. Family physicians in solo and small practices comprised the majority among all family physicians seeking board certification and were more likely to work in rural geographies. Extension programs and community health teams have the potential to support transformation within these practices. © 2016 Annals of Family Medicine, Inc.

    Full Text Available We present a participatory ethnobotanical experience from the development of research projects, university outreach work, and university volunteer programs in the rural areas of Paso Viejo (Pedanía Pichanas, Cruz del Eje. The objective was to identify and save plant resources of cultural interest, in addition to discuss the community and educational processes that promote participatory research (citizen science with local actors. Five workshops were held on the different themes of ethnobotany, such as environmental interpretation, local productive practices, traditional food, veterinary medicine and forage plants. In the context of the local cultural context, we registered a total of 88 uses in 49 wild species and 3 cultivated species; 7 uses are associated with food, 19 with veterinary medicine, 32 with forage, and 30 with other uses. University students participated in the organization, planning, and preparation of the resources used as well as fieldwork registration and systematization of workshops. The study discusses how the construction of a dialogical experience promotes greater reciprocity in the process of collection of ethnobotanical data and knowledge, resulting in an educational and pedagogical process.

    The aim of this work was to carry out a geochemical study of channel samples collected from six coal beds in the Marcelina Formation (Zulia State, western Venezuela) and to determine experimentally the gas content of the coals from the Paso Diablo mine. Organic geochemical analyses by gas chromatography-mass spectrometry and isotopic analyses on-line in coalbed gas samples were performed. The results suggest that the Guasare coals were deposited in a continental environment under highly dysoxic and low salinity conditions. The non-detection of 18??(H)-oleanane does not preclude that the organic facies that gave rise to the coals were dominated by angiosperms. In addition, the presence of the sesquiterpenoid cadalene may indicate the subordinate contribution of gymnosperms (conifers) in the Paleocene Guasare mire. The average coalbed gas content obtained was 0.6 cm3/g. ??13C and D values indicate that thermogenic gas is prevalent in the studied coals. Copyright ?? Taylor & Francis Group, LLC.

    1985-01-01

    The El Paso Formations consists of four members, in ascending order: Hitt Canyon, Jose McKelligon and Padre. Mounds in the McKelligon Member exposed in the southern Franklin Mountains were described by Toomey (1970). Most of these mounds are small but one large one is 5.8 m thick and about 13.7 m long in outcrop. The mound rock is chiefly bioclastic wackestone with minor packstone and boundstone. The varied fauna contains echinoderms, sponges and spicules, gastropods, trilobites, digitate algae, Nuia, Girvanella, Pulchrilamina, Calathium, and minor brachiopods and cephalopods. Intraclastic, bioclastic grainstone fills channels cut in the mounds. Similar, but smaller and less spectacular mounds occur in the McKelligon Member in the Florida, Big Hatchet, and Caballo Mountains, Lone Mountain, Cooke's Range, and elsewhere in southwestern New Mexico. A second type of mound is common in the upper part of the Hitt Canyon Member in the Cooke's Range, Red Hills, Caballo and Big Hatchet Mountains. These mounds also are typically small but one in the Red Hills is 13.7 m thick and about 30 m long in outcrop. The mound complex is about 75-80% SH-C and LLH-C stromatolite boundstone and bioclastic wackestone. The remaining 20-25% is bioclastic packstone and grainstone between the SH-C stromatolites and filling channels cut in the mound complex. The limited fauna contains small fragments of echinoderms, gastropods, trilobites, spicules, and Nuia.

    2015-02-01

    For the purpose to measure a rotation angle around the axis of an object, a non-contact rotation angle measurement method based on solo camera was promoted. The intrinsic parameters of camera were calibrated using chessboard on principle of plane calibration theory. The translation matrix and rotation matrix between the object coordinate and the camera coordinate were calculated according to the relationship between the corners' position on object and their coordinates on image. Then the rotation angle between the measured object and the camera could be resolved from the rotation matrix. A precise angle dividing table (PADT) was chosen as the reference to verify the angle measurement error of this method. Test results indicated that the rotation angle measurement error of this method did not exceed +/- 0.01 degree.

    Ultrasonic extraction followed by Stir Bar Sorptive Extraction (SBSE) and thermal desorption inline coupled with Gas Chromatography and Mass Spectrometry (TD/GC/MS)was used to perform a comprehensive determination of soil-borne polycyclic aromatic hydrocarbons (PAHs) in El Paso, Texas. The method provided good sensitivity and faster processing time for the analysis. The total PAHs in El Paso soil ranged from 0.1 to 2225.5 µg kg−1. Although the majority of PAH concentrations did not exceed the soil screening levels regulated by the United States Environmental Protection Agency, the existence of PAHs in this ecosystem is ubiquitous. Naphthalene were found in 100% of the soil samples; while the heavy PAHs (five- and six-ring) were not often detected and mostly remained in closer proximity to industrial areas and major traffic points. The results ruled out the possibility of petroleum refining as the significant source of local soil-borne PAH contamination, but they suggested that the PAHs found in El Paso soil were closely linked to human activities and possible other industrial processes.

We aimed to evaluate the effects of coating propolis extract on the physicochemical characteristics of papaya stored at room temperature. Solo papayas cv. 'Golden' were randomly divided into five postharvest treatment groups, three forms of dip-coating (70% alcohol, hydroalcoholic extract of propolis to 2.5%, and hydroalcoholic extract of propolis to 5% and two controls (one uncoated and one with refrigerated uncoated fruits. The weight loss, firmness, soluble solids (SS, titratable acidity (TA, SS/TA, and hydrogen potential (pH were evaluated at the intervals of 4 days every 12th storage day. Sensory analysis was performed on the 4th day of storage of papayas and evaluated by untrained through the acceptance testing. Treatments “refrigerated”, “propolis 2.5%”, and “5% propolis” presented with the lowest weight loss. The firmness level for treatment propolis 5% was superior to that of control, alcohol, and 2.5% propolis treatments. The SS was greater for propolis 5% treatment, which only differed from the alcohol treatment. The TA and SS/TA did not vary with the treatments, but with the storage time. The pH of refrigerated papaya showed significant differences in relation to other treatments. The fruits subjected to refrigerated treatment presented with chilling injury. Papayas coated with propolis extract showed sensory acceptability similar to that in other treatments on the 4th day of storage. The coating of propolis extract is a promising alternative for the control of weight loss and for the maintenance of firmness in Solo papaya cv. 'Golden'.

    To report our experience with solo-surgeon, single-port laparoscopic anterior resection (solo SPAR) for sigmoid colon cancer. Data from sigmoid colon cancer patients who underwent anterior resections (ARs) using the single-port, solo surgery technique (n = 31) or the conventional single-port laparoscopic technique (n = 45), between January 2011 and July 2016, were retrospectively analyzed. In the solo surgeries, making the transumbilical incision into the peritoneal cavity was facilitated through the use of a self-retaining retractor system. After establishing a single port through the umbilicus, an adjustable mechanical camera holder replaced the human scope assistant. Patient and tumor characteristics and operative, pathologic, and postoperative outcomes were compared. The operative times and estimated blood losses were similar for the patients in both treatment groups. In addition, most of the postoperative variables were comparable between the two groups, including postoperative complications and hospital stays. In the solo SPAR group, comparable lymph nodes were attained, and sufficient proximal and distal cut margins were obtained. The difference in the proximal cut margin significantly favored the solo SPAR, compared with the conventional AR group (P = .000). This study shows that solo SPAR, using a passive camera system, is safe and feasible for use in sigmoid colon cancer surgery, if performed by an experienced laparoscopic surgeon. In addition to reducing the need for a surgical assistant, the oncologic requirements, including adequate margins and sufficient lymph node harvesting, could be fulfilled. Further evaluations, including prospective randomized studies, are warranted.

Internal (self-contempt, positive self-evaluation and external criteria (musical rewards, successful solo performances, successful auditions of efficiency of solo music performance were taken into consideration. The research was grounded on studies from the field of sports psychology and on the few studies that were carried out in the field of psychology of music. The research was conducted on 94 students of Music Academy, grouped by gender and field of study (instrumentalists, solo vocalists and composers vs. students of music teaching. The symptoms of performance anxiety were measured by a part of the Performance Anxiety Questionnaire, and efficiency of solo music performance by the Efficiency of Music Performance Questionnaire. Both questionnaires were developed for the purpose of the study. The results reveal the interrelationship between the internal criteria of efficiency in solo music performance and performance anxiety. On the other hand, only trends of correlation were established between performance anxiety and the external criteria of solo music performance. The research findings imply the important role of cognition as a mediator between performance anxiety and performance efficiency.

O experimento foi realizado em condições de casa de vegetação em delineamento em blocos ao acaso, com parcelas em faixas e três repetições. Foi verificado que a aplicação do composto de lixo promoveu o aumento da CE dos solos. Todavia, esse efeito foi inferior àquele causado pelos adubos minerais. Os maiores valores de CE (> 2 dS m-1 foram causados pelas aplicações do composto + calcário + adubo nos solos ácidos e do composto + adubo + gesso nos solos alcalinos. Porém, quanto maior a capacidade de troca catiônica (CTC inicial dos solos ácidos e pH inicial dos solos alcalinos, menores foram os efeitos dos tratamentos sobre o incremento da CE. A aplicação do composto promoveu, também, o aumento do pH e a redução da acidez potencial. Esse efeito do composto foi, em média, superior àquele causado pela aplicação do calcário. A aplicação conjunta do composto e calcário promoveu um efeito aditivo de seus efeitos isolados sobre o pH e acidez potencial do solo. A adição dos adubos minerais tendeu a reduzir o pH por causa da acidificação residual da uréia. Esse efeito foi bem evidente nos solos alcalinos. O aumento do pH e da CE foi acompanhado por uma diminuição na diferença entre os valores de pH medido em CaCl2 e em água, notadamente nos solos ácidos. A aplicação do composto de lixo para melhorar a acidez do solo, manejando-se adequadamente o calcário e adubos minerais nos solos ácidos ou gesso nos solos alcalinos, parece ser uma prática agrícola viável.

    Full Text Available City of Surakarta, known as Solo City is one of cities in Central Java Province traversed by Bengawan Solo River. Heavy rainfall in upstream area of Bengawan Solo River causes increase in high water level at downstream. Bengawan Solo River will be higher than water level in drainage system which may induce a backwater flow. Since Colonization era, the government has built dikes and barrages against backwater flow and inundation problem. One of the barrages was Demangan Barrage dividing river flow into Bengawan Solo River and Pepe River. It was equipped with total capacity pump of 12,3 m3/s. The inundation is not only caused by the backwater flow coming from Bengawan Solo River, but also surface runoff as the result of the excess rainfall which cannot be drained gravitationally to the main river if the gate was closed. Therefore, comprehensive study combining hydrology and hydraulics analysis is highly needed in order to achieve more effective flood control management. Hydrology analysis was done to estimate the direct runoff hydrograph from catchment area in Solo City to downstream of Pepe River. While in hydraulics case, hydraulic parameter in downstream of Pepe River influenced by Bengawan Solo River stream was analyzed. Both studies were simulated using software HEC-RAS 4.1.0 version. The simulation considered drainage channel, gate, pump system and dike in Pepe River downstream. Simulation using 10 years of return period in Solo City and average annual water level in Bengawan Solo River showed that Pepe River can flow through the gate, while the highest water level is still below the dike. Simulation considering 10 years of return period, water level hydrograph of Bengawan Solo River, existing pump, and gate operation inferred that Pepe River surpassed top of dike. Capacity of required pump should be more than 168,3 m3/s in order to pass 10 years of return period. By combining operational of existing pump and dike elevated up to +87,63 m

En este contexto, el presente estudio tuvo como objetivo diagnosticar la situación de la arborización urbana en el barrio Jardín Brasil en Bauru, São Paulo, Brasil, a través de un levantamiento cualitativo y cuantitativo de las especies arbóreas presentes. Fue posible registrar 23 familias y 41 especies en un total de 510 individuos de los cuales 11 estaban muertos. El barrio tiene una diversidad relativamente baja y la mayoría de las especies encontradas son exóticas (60,98%. Las especies más comunes son: Licania tomentosa (31,87%, Caesalpinia peltophoroides (11,16%, Lagerstroemia indica (9,56%, Murraya paniculata (6,57% y Terminalia catappa (5,98%. Gran parte de los problemas encontrados son el resultado de no planificar la silvicultura urbana, lo que termina generando conflicto con el cableado eléctrico y la construcción. Entre tanto, fueron pocos los casos de conflictos con el alumbrado público y las señales de tránsito. Se destacó también el gran número de individuos arbóreos atacados por termitas y hormigas (59,34%. Investigaciones como ésta son útiles para la toma de decisiones y la planificación de los árboles urbanos de una ciudad.

    Full Text Available Objetivos. Explorar los mitos sobre la donación de órganos en un hospital nacional de Lambayeque-Perú, en el año 2014. Materiales y métodos. Se realizó un estudio cualitativo-fenomenológico con veinticuatro entrevistas a profundidad no estructuradas a personal de salud, potenciales receptores y familiares de potenciales donantes. El muestreo fue intencional opinático finalizado por saturación teórica de cada estamento. Se utilizó una guía de entrevista evaluada por cinco expertos. Se realizó triangulación de datos. Resultados. Veintitrés entrevistados (95,8% mostraron actitud favorable hacia la donación de órganos. En el Documento Nacional de Identidad, trece (54,2% refieren "no" a la donación. Los mitos fueron: la edad o enfermedades contraindican la donación; el receptor de un órgano experimenta actitudes de su donador y vive en él; la muerte cerebral es inmovilidad del cuerpo y un estado reversible; las religiones no aceptan la donación de órganos, esta afecta la integridad física y la resurrección, y existen preferencias en la lista de espera de donantes así como el tráfico de órganos. Conclusiones. Los mitos explorados en el presente estudio muestran perspectivas religiosas, socioculturales, psicológicas y éticas. La aparente falta de conocimiento del diagnóstico de muerte cerebral es el punto de partida que marca el proceso de donación. La existencia de un coordinador hospitalario, el rol de los guías espirituales y la correcta información brindada por medios de comunicación serían piezas clave para derribar estos mitos.

    Although recent typologies of female sexual offenders have recognized the importance of having a co-offender, the clinical characteristics of solo and co-female sexual offenders remain poorly understood. The aim of this study was to compare solo (n = 20) and co- (n = 20) female sexual offenders on a variety of clinical characteristics. It was found that although solo and co-offenders reported similar developmental experiences and psychological dispositions, differences were found in environmental niche, offense preceding, and positive factors. Specifically, solo offenders demonstrated a greater presence of personal vulnerabilities including mental health and substance abuse difficulties. Co-offenders reported a greater presence of environmentally based factors, including a current partner who was a known sex offender and involvement with antisocial peers. It is suggested that these results have implications for understanding assessment and intervention needs for these groups of sexual offenders. © The Author(s) 2014.

    Selective memorising of isolated facts or reproducing what is thought to be required - the surface approach to learning - is not the desired outcome for a dental student or a dentist in practice. The preferred outcome is a deep approach as defined by an intention to seek understanding, develop expertise and relate information and knowledge into a coherent whole. The aim of this study was to investigate whether the structure of observed learning outcome (SOLO) taxonomy could be used as a model to assist and promote the dental students to develop a deep approach to learning assessed as learning outcomes in a summative assessment. Thirty-two students, participating in course eight in 2007 at the Faculty of Odontology at Malmö University, were introduced to the SOLO taxonomy and constituted the test group. The control group consisted of 35 students participating in course eight in 2006. The effect of the introduction was measured by evaluating responses to a question in the summative assessment by using the SOLO taxonomy. The evaluators consisted of two teachers who performed the assessment of learning outcomes independently and separately on the coded material. The SOLO taxonomy as a model for learning was found to improve the quality of learning. Compared to the control group significantly more strings and structured relations between these strings were present in the test group after the SOLO taxonomy had been introduced (P SOLO taxonomy is recommended as a model for promoting and developing a deeper approach to learning in dentistry.

    Stentless biological valves have proven advantages in hemodynamic performance and left ventricular function compared to stented biological valves. Following a marked postoperative fall in the platelet count of patients after implantation of the Freedom SOLO valve, the study aim was to confirm clinical observations that this effect was more severe in patients receiving Freedom SOLO valves than in those receiving St. Jude Medical (SJM) mechanical aortic valves. Preoperative and postoperative platelet counts were compared in two groups of patients who underwent aortic valve replacement (AVR) without any concomitant procedures between January and December 2007. Patients received either a Freedom SOLO valve (n = 28) or a SJM mechanical valve (n = 41). Mean values of platelet counts were compared using three multiple linear regression models. Platelet counts were significantly lower in the Freedom SOLO group than in the SJM group from the first postoperative day (POD 1) up to POD 6 (p SOLO group the platelet count fell below 30x10(9)/l, while the lowest level in the SJM group was 75x10(9)/l. Based on multiple linear regression models, the type of valve implanted had a statistically significant influence on postoperative platelet counts on POD 1, POD 3, and POD 5 (p SOLO group.

    Sister chromatid cohesion is essential to maintain stable connections between homologues and sister chromatids during meiosis and to establish correct centromere orientation patterns on the meiosis I and II spindles. However, the meiotic cohesion apparatus in Drosophila melanogaster remains largely uncharacterized. We describe a novel protein, sisters on the loose (SOLO), which is essential for meiotic cohesion in Drosophila. In solo mutants, sister centromeres separate before prometaphase I, disrupting meiosis I centromere orientation and causing nondisjunction of both homologous and sister chromatids. Centromeric foci of the cohesin protein SMC1 are absent in solo mutants at all meiotic stages. SOLO and SMC1 colocalize to meiotic centromeres from early prophase I until anaphase II in wild-type males, but both proteins disappear prematurely at anaphase I in mutants for mei-S332, which encodes the Drosophila homologue of the cohesin protector protein shugoshin. The solo mutant phenotypes and the localization patterns of SOLO and SMC1 indicate that they function together to maintain sister chromatid cohesion in Drosophila meiosis.

    Cerro Solo, located in Chubut, Argentina, is a sandstone type uranium-molybdenum deposit. Good recovery of both elements can be achieved by acid leaching of the ore but the presence of molybdenum in pregnant liquors is an inconvenient to uranium separation and purification. A two steps process is developed. A selective alkaline leaching of the ore with sodium hydroxide allows separating and recovering of molybdenum and after solid-liquid separation, the ore is acid leached to recover uranium. Several samples averaging 0,2% uranium and 0,1% molybdenum with variable U/Mo ratio have been used and in both steps, leaching and oxidant reagents concentration, temperature and residence time in a stirred tank leaching have been studied. In alkaline leaching molybdenum recoveries greater than 96% are achieved, with 1% uranium extraction. In acid leaching up to 93% of the uranium is extracted and Mo/U ratio in solvent extraction feed is between 0,013 and 0,025. (author)

    Full Text Available OBJECTIVE: To compare demographics and motivations for falls from bridges at the United States-Mexico border and in El Paso County, Texas, and to analyze injuries and injury patterns to support intentionality and to provide treatment recommendations. METHODS: A retrospective observational review was conducted of hospital admissions to a trauma center after falls from bridges from 1995 to 2009. Statistical methods used were chi-square testing, T-test for means comparison, univariate correlations, and regression analysis. RESULTS: Of the 97 evaluated patients, 81.4% fell from U.S.-Mexico border bridges, including one patient who fell from a railway bridge; 74.7% of those falling from border bridges had a non-U.S. address, contrasting with 22.2% of those who fell within the United States. Falls over the border were associated with more immigration-related motivations and fewer suicide attempts. Injuries included lower extremities in 76 (78.4% and thoracolumbar spine in 27 (27.8% patients; 16 patients with a thoracolumbar spine fracture (59.3% also had a lower extremity injury. Mean hospital length of stay was 7.2 days. Mean injury severity score was 8.45 (range 1-43. Age, injury severity score, and pelvic fracture increased the hospital length of stay. CONCLUSIONS: Patients fell while emigrating-immigrating based on residence and motivating factors. A dyad of lower extremity and thoracolumbar spine injuries coincided in 59.3% of those with a thoracolumbar spine injury; thoracolumbar spine imaging of patients evaluated after falls from bridges is recommended. Proposed prevention strategies include posting signs on bridges and installing catch-net safety barriers.OBJETIVO: Comparar la información demográfica y las motivaciones relacionadas con las caídas desde puentes que atraviesan la frontera entre México y los Estados Unidos en el condado de El Paso, Texas; analizar las lesiones y los patrones de lesiones que avalan la intencionalidad; y

    Study Objective The aim of this study was to evaluate Emergency Medical Services (EMS), use, injury mechanisms, prehospital assessments, and injuries among those receiving aid from the United States Border Patrol (USBP) in the El Paso (Texas USA) Sector. This is a time-series, retrospective analysis of all prehospital data for injuries among patients receiving care from USBP EMS on the US Mexico border in the El Paso sector from February 6, 2014 to February 6, 2016. A total of 473 documented EMS encounters occurred in this two-year period and demonstrated a male gender predominance (male 63%; female 37%) with the most prominent ages between 22-40 years old. The most prevalent EMS call types were medical (55%) and trauma (42%). The most common chief complaints were an injured or painful extremity (35%) and rash (13%). The most common USBP EMS provider primary impression was traumatic injury (34%), followed by fever/infection (17%) and extremity injury (7%); however, the most common secondary impression was also extremity injury (20%). The most common mechanism of injury was fall (26%) and motor vehicle accident (MVA; 22%). The USBP EMS was the first provider on scene in 96% of the MVAs. The author reports on injury patterns, mechanisms, chief complaints, EMS impressions, as well as demographics of patients reporting to USBP EMS. A knowledge of these injury patterns will be useful to EMS administrators and physicians along the US Mexico border. Baker RA .

    Full Text Available Muitas pesquisas conferem maior peso na alta declividade do terreno como fator decisivo no processo hidro-erosivo. Porém, foi avaliado que baixas declividades (~4º já são suficientes para se iniciar o escoamento superficial. A pesquisa teve como objetivo fazer uma caracterização físico-química de solo degradado, monitorar o seu potencial matricial e o processo de formação de escoamento em uma sub-bacia do rio Maranduba - Ubatuba/SP, em encosta com baixa declividade. O trabalho se baseou na instalação de parcelas de erosão em solo sem cobertura vegetal para analisar as perdas de solo e água, bem como as propriedades físicas e químicas do solo (Porosidade, textura, densidade, pH e matéria orgânica. As parcelas se localizam na parte intermediária de um morrote com encosta retilínea, esse sofreu alteração em sua morfologia original por meio de um corte de encosta (UTM: 0474211/7395934.  O solo do local é um Latossolo que apresenta o horizonte B exposto. Cerca de 6,9 t/ha de solo foram perdidos durante o monitoramento (01 agosto 2013-20 dezembro 2014 e mais de 5.354,7 m3 de água foram escoados superficialmente. Salienta-se a fragilidade dos ambientes degradados de baixa declividade frente às altas taxas de perdas de solo e água, que, no período de 17 meses de monitoramento e com chuvas dentro da normalidade para o município, totalizaram 63 dias com ocorrências de escoamento, em solos que tendem à saturação por períodos prolongados. Portanto, o transporte das partículas de solo superficialmente está atrelado à baixa drenagem do terreno e à perda da resistência do solo, corroborando em períodos longos de umidade antecedente, sendo este um dos fatores decisivos para se iniciar o escoamento superficial.

    Full Text Available Estudos foram realizados no Departamento de Ciência do Solo da Universidade Federal de Lavras (MG, no período de novembro/1999 a janeiro/2000, com o objetivo de avaliar a sobrevivência de estirpe e isolados de rizóbio em solo contaminado com metais pesados e verificar a relação entre tolerância do rizóbio a metais pesados em meio de cultura e sua sobrevivência em solo contaminado. Foram utilizados os dois microrganismos mais tolerantes [BR-4406 (estirpe recomendada para Enterolobium spp. e UFLA-01-457 (isolado de solo contaminado, ambos pertencentes ao gênero Bradyrhizobium ] e os dois mais sensíveis (UFLA-01-486 e UFLA-01-510, isolados de solo contaminado, pertencentes ao gênero Azorhizobium , todos selecionados de um grupo de 60estirpes/isolados em estudos prévios deste laboratório, em meio de cultura suplementado com metais pesados.Empregaram-se misturas de um Latossolo Vermelho-Escuro (LE que continham 0, 15 e 45% (v/v de um Latossolo Vermelho-Amarelo plíntico contaminado com Zn, Cd, Pb e Cu. As misturas de solo contaminado foram inoculadas com 20mL de cultura em YM na fase log das estirpes mencionadas, as quais foram testadas separadamente com três repetições. A avaliação do número de células viáveis no solo, realizada aos 0, 7, 14, 21 e 28dias de incubação, pelo método das diluições sucessivas e inoculação em placas com meio YMA, revelou comportamento diferenciado entre os organismos estudados.

    Full Text Available O uso de fertilizantes que contêm baixos teores de enxofre (S, em solos com baixos teores de matéria orgânica, pode resultar em limitação desse nutriente para as culturas. O uso do S-elementar como fertilizante, isoladamente ou associado a fórmulas comerciais, pode reduzir os custos de adubação em solos deficientes de S. Os objetivos deste estudo foram: a verificar se, em dois solos tropicais, ocorre oxidação de S-elementar; b avaliar se o período de incubação de seis dias sugerido por Janzen & Bettany (1987a é adequado para estimar a oxidação do S-elementar e c medir o efeito da oxidação do S-elementar sobre o pH do solo. Para isso, foi realizado um experimento com amostras de um ARGISSOLO VERMELHO AMARELO eutrófico abruptíco e de um LATOSSOLO VERMELHO DISTRÓFICO típico. As amostras dos dois solos foram incubadas com seis doses de enxofre (0, 1,5, 3,0, 6,0 9,0 e 12g de So kg-1 de solo por períodos entre 0 e 70 dias. A incubação foi feita em estufa, a uma temperatura de 27o + 1o C. Ambos os solos tiveram capacidade para oxidar o S-elementar para S-sulfato, forma disponível à planta. No argissolo, o teor de S-sulfato resultante da oxidação do S-elementar foi 563mg dm-3 de solo, enquanto que, no latossolo, foi de 207mg dm-3 de solo, indicando capacidade diferenciada de ambos para oxidar o S-elementar. Em ambos os solos houve diminuição do pH, sendo mais acentuada para o argissolo. O período de incubação para avaliação da oxidação do S-elementar de seis dias sugerido por Janzen & Bettany (1987a parece ser insuficiente.

    Full Text Available A pesar de los grandes avances en la cardiología en el siglo XX y XXI, la insuficiencia cardiaca sigue suponiendo la principal causa de hospitalización en las personas ancianas y presentando un pronóstico ominoso. Además, a pesar de los múltiples estudios sobre nuevas dianas farmacológicas, apenas hemos avanzado en el campo del tratamiento, tal vez porque aún existen lagunas en su fisiopatología. No debemos olvidar que la insuficiencia cardiaca es un compendio de signos y síntomas que engloban múltiples órganos y sistemas.  Mucho se está investigando sobre la relación entre riñón y corazón en forma de síndrome cardiorrenal.  Algo cada vez más en boga es el papel del abdomen en la disfunción orgánica de la insuficiencia cardiaca. En ese sentido, el sistema venoso contiene el 70% del volumen sanguíneo, siendo almacenado en su mayor parte dentro de las vísceras abdominales. Un aumento del tono simpático supone aumento intenso del retorno venoso tan importante como para  aumentar las presiones de llenado y justificar una descompensación cardiaca. La congestión sistémica determina un aumento en la presión intraabdominal que está correlacionada con la disfunción renal en la insuficiencia cardiaca avanzada. La hipoperfusión tisular intestinal supone microtraslocación bacteriana promoviendo el status proinflamatorio típico de este síndrome. La visión holística e integrada de la insuficiencia cardiaca puede suponer un avance tanto en la estratificación del riesgo como en las estrategias terapéuticas. Grandes pasos se están dando en este sentido con estudios sobre la ultrafiltración, paracentesis, diálisis peritoneal, suero hipertónico o fármacos adsorbentes del sodio.

    Full Text Available El proyecto de Reforma Constitucional llamado de las Garantías Económicas, pretende ser una solución frente a un problema -el fiscal- que captura un gran interés en la opinión pública de Costa Rica. Se sustenta en una serie de ideas preconcebidas habituales en esta materia, la mayor de las cuales es la incorrecta suposición de que este problema fiscal es el más importante en la economía costarricense. Como propuesta de solución tiene el atractivo de la simplicidad, aparte fundarse en una opción ideológica que rechaza la participación activa del Estado, y la cual es predominante en influyentes sectores de la sociedad de Costa Rica. En ese sentido, su aprobación -particularmente en su versión original o en la sustentada por el Partido Unidad- impondría una severa limitación al accionar del Estado, la cual operaría a priori como mandato constitucional superior. Ello tendría la consecuencia antidemocrática de forzar a la aplicación de una reforma del Estado de la que estaría ausente todo mecanismo de concertación social, y en la cual habrían sido omitidos a priori temas fundamentales como el de la regresividad de la estructura tributaria, el de la desvinculación de esta con relación a la estructura productiva y el de la no correspondencia entre la organización y funcionamiento del Estado y las necesidades y demandas de los grupos sociales de nivel medio y bajo. Por los limitados márgenes de maniobra en que históricamente se ha movido la política fiscal, sus consecuencias para esta no serían muy significativos, pero en cambio sí lo sería para el cumplimiento del papel que es indispensable que el Estado asuma en el desarrollo social y económico. Por lo anterior y, además, por sus ligámenes no explícitos con las propuestas para una política monetaria liberalizante y desreguladora, las Garantías constituirían un paso adelante de decisiva importancia hacia la plena vigencia de los mecanimos del "libre" mercado como

    Full Text Available Las evidencias observacionales indican que durante las últimas décadas el clima de Cuba se ha hecho más cálido, se ha observado un incremento de los totales de precipitación en el período poco lluvioso y un cierto decrecimiento en el período lluvioso, y la frecuencia de sequías se ha incrementado significativamente desde 1960. El objetivo de este trabajo fue determinar, en las marchas anuales de la temperatura del aire de cada estación meteorológica en la zona más occidental de Cuba, las fechas del paso de la temperatura media del aire por encima y por debajo de 25°C y la duración de esos períodos, enmarcar los períodos lluvioso y poco lluvioso, y obtener su relación con la fecha del paso de la temperatura media del aire por el umbral señalado. Se comprobó que las regularidades encontradas en las relaciones "paso de la temperatura por encima de 25°C - inicio del período lluvioso" y "paso de la temperatura por debajo de 25°C - inicio del período poco lluvioso" durante el período de referencia 1950-1975 ya no constituyen regularidades en el período de referencia 1976-2005, principalmente en el período en que la temperatura media del aire pasa por debajo de los 25°C, donde los desaciertos alcanzaron las mayores desviaciones. La duración media del período con temperaturas superiores a 25°C muestra una tendencia al aumento, obteniéndose una longitud mayor durante este período que la observada en el período con temperaturas inferiores a 25°C.

    Full Text Available OBJECTIVE: To consider whether or not deinstitutionalization and the integration of community mental health care with primary health care services have reduced stigma toward mental illness in Jamaica. METHODS: A qualitative study of 20 focus groups, with a total of 159 participants grouped by shared sociodemographic traits. Results were analyzed using ATLAS.ti software. RESULTS: Participant narratives showed that stigma had transitioned from negative to positive, from avoidance and fear of violent behavior during the period of deinstitutionalization to feelings of compassion and kindness as community mental health services were integrated with Jamaica's primary health care system. The Bellevue Mental Hospital and homelessness were identified as major causes of stigma. CONCLUSIONS: Attitudes toward the mentally ill have improved and stigma has decreased since the increase of community involvement with the mentally ill. This reduction in stigma seems to be a result of the rigorous deinstitutionalization process and the development of a robust community mental health service in Jamaica.OBJETIVO.

Se ilustra el caso de un paciente colostomizado a causa de un cáncer de recto. Los datos se recogieron mediante entrevistas semiestructuradas al paciente y al familiar en dos tiempos distintos, durante la hospitalización y a los dos años. Las cuatro entrevistas se grabaron, trascribieron y analizaron según el método de Taylor-Bogdan. Resultados: Durante la hospitalización priman las estrategias de afrontamiento dirigidas a aliviar las emociones negativas delegando los cuidados del estoma en su familiar. A los dos años se observa una preocupación mayor por las cuestiones prácticas logrando finalmente ser autónomo. Se descubren los aspectos que han contribuido a esa adaptación y los cambios provocados por la ostomía en su vida. Conclusiones: Se evidencia la necesidad de un cuidado individualizado que considere al ostomizado en su dimensión biopsicosocial.Objective: Knowing how a person deals with and adapts to a colostomy along a two years period. Methods: Qualitative case study. The case shows a colostomyzed patient due to a rectal cancer. Data collected through semistructured interviews to the patient and a relative at two different moments: during hospitalization and two years later. The four interviews were recorded, transcribed and analyzed according to Taylor-Bogdan Method. Results: Confrontation strategies aimed at alleviate negative emotions by delegating the cares of the stoma to relatives are key during hospitalization. Two years later, there is a higher concern for practical questions and the patient can finally reach autonomy. The report shows the aspects leading to adaptation and the changes the ostomy brings about in the patient's life. Conclusions: Ostomyzed people require individualized care based on their biopsycosocial dimension.

    Full Text Available ABSTRACT: The long lasting opposition between qualitative and quantitative methods for studying behaviour has been overridden by interdisciplinary work in which methods can be combined to approach animal and human behaviour, thus contributing to drawing rigorous and useful conclusions. We show an example of this by combining a quasi-experimental design and descriptive methods to study working memory for the resolution of a spatial problem task (the Tower of Hanoi in a neuropsychiatric hospital inpatient with amnesia and executive deficits. Results from the quasi-experiment showed that the patient acquired strategies to solve the task with a high level of efficiency (F3/35 = 7, 19, p < .01. Qualitatively speaking, the patient developed more than one strategy to solve the problem, which indicates the presence of learning based on working memory. In the light of these findings, we discuss issues of mixed methods research and suggest the importance of developing mixed methods to study behaviour. RESUMEN: La oposición duradera entre métodos cualitativos y cuantitativos para estudiar el comportamiento ha sido anulada por el trabajo interdisciplinario en que los métodos pueden combinarse para enfocar el comportamiento humano y animal, contribuyendo así a obtener conclusiones útiles y rigurosas.

Métodos Estudio cualitativo del tipo “investigación-acción”. Se realizaron 19 entrevistas semiestructuradas y se armaron nueve grupos de discusión a distintos niveles del sistema público de salud chileno. El análisis se realizó mediante el software Atlas ti® y en forma manual, desde un marco de análisis de contenido, mediante la categorización y codificación de la información según dimensiones preespecificadas y con la inclusión de categorías emergentes cuando fue pertinente. Resultados El principal desafío de implementación de recomendaciones mencionado es la falta de un proceso explícito y estructurado. Los actores del sistema de salud reconocen dificultades dependientes del contexto al momento de usar las recomendaciones. En esta experiencia inédita de revisión institucional, los participantes sugirieron una serie de estrategias a poner en práctica para superar dichos desafíos, representadas en un flujograma de gestión optimizada para el desarrollo e implementación de GPC. El mismo proceso ha permitido tomar conciencia de la importancia de la implementación de GPC en Chile. Conclusión Tras caracterizar el proceso de implementación, barreras y facilitadores se articuló un plan de implementación de recomendaciones que permitiría orientar y monitorizar dicho proceso. Hacer partícipes del proceso de revisión a informantes claves dentro y fuera del Ministerio de Salud facilitaría la implementación de estrategias y la introducción de mejoras al proceso de desarrollo de GPC. Estudios de este tipo deberían ser realizados en médicos y pacientes para complementar la información recogida.

Este estudio pretende conocer cómo perciben la calidad de la atención domiciliaria los cuidadores familiares de pacientes con cáncer en fase terminal, ancianos con demencia y personas intervenidas en programadas de cirugía mayor ambulatoria. Métodos: Estudio cualitativo de tipo fenomenológico basado en grupos de discusión (9, grupos triangulares (5 y entrevistas en profundidad (22. El estudio se realizó en Andalucía, durante los años 1999 y 2000. Los sujetos del estudio son los cuidadores principales de los pacientes que reciben atención domiciliaria desde los centros de salud. La información se ha analizado mediante análisis de contenido apoyado por el software NUDIST- 4. Las variables de análisis han sido las del modelo SERVQUAL. Resultados. Para las cuidadoras de pacientes con cáncer las dimensiones más importantes de la calidad de la atención domiciliaria son la Capacidad de Respuesta y la Accesibilidad. Elementos negativos que perjudican la accesibilidad son: la falta de cobertura de atención domiciliaria fuera del horario normal, la dificultad de contactar por teléfono, la tardanza en acudir y las visitas sólo a demanda. Las cuidadoras de pacientes intervenidos en cirugía mayor ambulatoria quieren Seguridad y la Fiabilidad. Las cuidadoras de ancianos con demencia consideran prioritario que se les proporcionen los materiales que necesitan para cuidar al enfermo. Conclusiones: Las expectativas de cuidadores y pacientes varían en función del problema de salud. Por lo tanto, las características de la atención domiciliaria tendrán que variar también en función de ello. Se hace necesario un modelo flexible que sea capaz de adaptarse a las necesidades de los diferentes tipos de pacientes y las circunstancias también distintas de sus cuidadores familiares.

Dicho principio es observable como un factor que contribuye a la competencia comunicativa de los hablantes de una lengua dada. Esta investigación se ha basado en un conjunto de encuestas en las que los sujetos debían seleccionar variantes léxicas en parejas de unidades, diferenciadas a priori como 'formales' o 'informales'.

    This paper examines human-nature interaction and how therapeutic this relationship is by investigating the efficacy of structured outdoor experience. Two walking and solo experience (WSEs) explored university students' (aged 20-43 years) perceptions of walking through and being with nature. The first was a 5-day journey (n = 4; 3 females and 1 male) and the second (n = 5; 3 females and 2 males) took place over two weekends, with a 2-week interval in-between. Pre- and post-experience interviews, journal writing, group discussions and a 9-month follow-up interviews were used to collect data and thematic analysis [Braun and Clarke (Using thematic analysis in psychology. Qual Res Psychol 2006;3:77-101.)] was applied. Both WSEs were considered together during analysis, as well as comparisons made between the two, in order to evaluate implications for practice. Benefits of the WSE that contributed to a general sense of well-being were: (i) gaining a sense of freedom and escape; (ii) gaining a sense of awareness and sensitivity to one's environment and its influence (iii) gaining confidence in being able to cope and take action; (iv) gaining a sense of perspective on and appreciation for life. Furthermore, the meaning participants formed in relation to their environment before, during and after the WSE, and the activity within that environment, played a role in their sense of well-being and in their motivations to re-access nature in other places. Findings suggest that WSEs are a cost effective way to give rise to beneficial and durable experiences, but a more holistic approach to policy is needed. © The Author 2016.

    Full Text Available El 29 de octubre de 2005 el huracán Beta, de categoría 1 pasó a 15 km norte de la isla de Providencia, Caribe colombiano. Con el propósito de determinar eventuales cambios estructurales de las praderas de fanerógamas marinas, se monitorearon cuatro praderas de Thalassia testudinum Banks ex König alrededor de la isla, uno y dos años después del paso del huracán. Se seleccionaron dos sitios no afectados y dos afectados por el paso del huracán. Se observó que las praderas de pastos marinos en la isla de Providencia parecen sanas y sin signos de alteraciones significativas ocasionadas por el huracán Beta. La única posible alteración de tipo estructural, fue devolver a un estado sucesional más temprano a este ecosistema en las zonas afectadas, alteración que actualmente parece haberse superado.

    Wei Luo

    Full Text Available Equine degenerative suspensory ligament desmitis (DSLD in Peruvian Paso horses typically presents at 7-15 years and is characterized by lameness, focal disorganization of collagen fibrils, and chondroid deposition in the body of the ligament. With the aim of developing a test for disease risk (that can be used to screen horses before breeding we have quantified the expression of 76 TGFβ-signaling target genes in adipose-derived stromal fibroblasts (ADSCs from six DSLD-affected and five unaffected Paso horses. Remarkably, 35 of the genes showed lower expression (p<0.05 in cells from DSLD-affected animals and this differential was largely eliminated by addition of exogenous TGFβ1. Moreover, TGFβ1-mediated effects on expression were prevented by the TGFβR1/2 inhibitor LY2109761, showing that the signaling was via a TGFβR1/2 complex. The genes affected by the pathology indicate that it is associated with a generalized metabolic disturbance, since some of those most markedly altered in DSLD cells (ATF3, MAPK14, ACVRL1 (ALK1, SMAD6, FOS, CREBBP, NFKBIA, and TGFBR2 represent master-regulators in a wide range of cellular metabolic responses.

    Full Text Available El presente artículo provee una visión de las dificultades y pérdida de tiempo, debido al choque cultural, sufridos por algunos miembros de una red llamada La Red Juárez-El Paso (REDCJELP , la cual se conforma por empresarios mexicanos que abandonaron sus locales en Ciudad Juárez debido al aumento de la inseguridad en el 2008, llevando sus empresas a la vecina ciudad de El Paso, a manera de continuar sus operaciones en un ambiente más seguro. De tal forma que las características de patrimonio cultural entre ambas ciudades se convirtieron en barreras para dichos negocios, ya que ambos estilos chocaron uno contra el otro debido a prácticas empresariales diferentes y contrastantes. Durante la discusión se destacan detalles importantes del rol de la inseguridad en la ciudad, pero también acerca de la colisión de patrimonio cultural que causó el retorno de algunos de esos empresarios a Ciudad Juárez a manera de preservar su patrimonio cultural empresarial, además de recuperar la identidad perdida por establecerse en los Estados Unidos. Se realizó un análisis de los esfuerzos llevados a cabo por dicha red para producir un grupo consolidado de empresarios mexicanos preocupados por hacer prevalecer su patrimonio cultural y una mejor calidad de vida.

    Full Text Available This article tries to analyze the franchise business system of Ayam Bakar Wong Solo Restaurant through the Islamic economics perspective. The franchise business system applied by the Ayam Bakar Wong Solo is a cooperation (shirkah with the type of shirkah mudârabah, where there is a cooperation between the Ayam Bakar Wong Solo as a manager (mudârib and investors as owners of capital (sahib al-mâl. Both parties allied in the venture capital and the advantage of the alliance is divided in accordance with the agreements that have been agreed between the two. The Ayam Bakar Wong Solo offers two forms of shirkah mudârabah, namely mudârabah mutlaqah and mudârabah muqayyadah. It is found that there is a correspondence between the execution of the Ayam Bakar Wong Solo franchise and shirkah mudârabah practices in Islamic economics because the franchise system which is run has been suitably qualified and has met the rukn of shirkah mudârabah. However, there is a concept of franchis-ing which is more in line with Islamic economics, namely the principle of sharing in mudârabah and mushârakah as a substitute for a franchise concept with franchise fee and royalty fee.

    Active videogames (AVGs) have potential in terms of physical activity and therapy for children with cerebral palsy. However, the effect of social interaction on AVG play has not yet been assessed. The objective of this study is to determine if multiplayer AVG versus solo affects levels of energy expenditure and movement patterns. Fifteen children (9.77 [standard deviation (SD) 1.78] years old) with hemiplegic cerebral palsy (Gross Motor Function Classification System Level I) participated in solo and multiplayer Nintendo(®) "Wii™ Boxing" (Nintendo, Inc., Redmond, WA) AVG play while energy expenditure and punching frequency were monitored. Moderate levels of physical activity were achieved with no significant differences in energy measures during multiplayer and solo play. Dominant arm punching frequency increased during the multiplayer session from 95.75 (SD 37.93) punches/minute to 107.77 (SD 36.99) punches/minute. Conversely, hemiplegic arm punching frequency decreased from 39.05 (SD 29.57) punches/minutes to 30.73 (SD 24.74) punches/minutes during multiplayer game play. Children enjoyed multiplayer more than solo play. Opportunities to play AVGs with friends and family may translate to more frequent participation in this moderate physical activity. Conversely, increased hemiplegic limb use during solo play may have therapeutic advantages. As such, new strategies are recommended to promote use of the hemiplegic hand during multiplayer AVG play and to optimize commercial AVG systems for applications in virtual reality therapy.

    Freedom Solo is a stentless biological aortic valve which is implanted supra-annularly with a single suture line. An increased risk of postoperative thrombocytopenia in the early postoperative period has been reported in recent studies. In our study we evaluated postoperative haemodynamic performance and thrombocyte-levels. Thirty seven patients who underwent valve implantation of the Sorin Freedom Solo stentless valve were included. The haemodynamic performance of the valve was evaluated by transthoracic echocardiography postoperatively at the fourth day (mean) and after a median of 4.2 months. The mean gradient (mmHg) of Freedom Solo was 7.5 at four days and 8.6 at 4.2 months. Postoperatively no patient had more than grade 1 leakage. Seven percent of the patients had a reduction of thrombocytes to less than 20% of the preoperative level. Seventy six percent had a minimum postoperative thrombocyte level less than 100*10(9)/L. The 30 days mortality in our patient material was zero. Implantation of the Freedom Solo valve was uncomplicated in our experience. Favourable transvalvular gradients and no significant leaks were found. In accordance with the literature, we found a high percentage of patients having a postoperative level of thrombocytes less than 100*10(9)/L after implantation of Freedom Solo.

    The purpose of this investigation was to assess the effects of earplugs on acoustical and perceptual measures of choral and solo sound. The researcher tested the effects of musician's earplugs on choral and solo timbre and singer perceptions. Members of an intact women's university choir recorded Dona Nobis Pacem under two conditions, no earplugs and with earplugs over time. Approximately half of the choir members also participated as soloists, recording Over the Rainbow under the same two conditions. All recordings were analyzed using long-term average spectra (LTAS). After participating in each recording session, the participants responded to a questionnaire about ability to hear self (solo and choral context) and ability to hear others (choral context) under two conditions, no earplugs and with earplugs. LTAS results revealed that wearing earplugs in a choral setting caused decreased mean signal energy (>1 dB), resulting in less resonant singing. LTAS results also indicated that wearing earplugs in a solo setting had less effect on mean signal energy, resulting in a mean difference solo setting. Findings from this study could provide important information when structuring hearing conservation strategies. Copyright © 2017 The Voice Foundation. Published by Elsevier Inc. All rights reserved.

    Full Text Available RESUMO Com o objetivo de avaliar a sobrevivência de Macrophomina phaseolina em solo submetido a diferentes coberturas, conduziu-se dois experimentos em casa de vegetação, no delineamento inteiramente casualizado, em esquema fatorial 5 x 2, com cinco coberturas (Brachiaria brizantha, Pennisetum glaucum, Crotalaria spectabilis, solo coberto com filme de polietileno e solo sem cobertura e solo esterilizado e não esterilizado. No primeiro experimento, as plantas foram cultivadas em vasos e dessecadas, para posterior plantio do feijão-caupi e no segundo, a semeadura da cultura foi realizada em sucessão ao primeiro cultivo. Nos dois experimentos foram colocadas em cada vaso a 10 cm de profundidade, no dia do plantio da cultura, quatro bolsas de tecido contendo, cada uma, 10 gramas de inóculo de M. phaseolina, das quais, duas foram retiradas aos 30 dias após o plantio e duas no final do ciclo da cultura, para posterior plaqueamento e determinação da sobrevivência. Realizou-se também o monitoramento das temperaturas máximas e mínimas diárias do solo. Os tratamentos com solo coberto com material vegetal apresentaram menor elevação da temperatura em relação ao solo coberto com filme de polietileno e sem cobertura, que elevaram a temperatura em até 5,9 e 3,9 ºC, respectivamente, em relação ao solo coberto com palhada de P. glaucum. O solo coberto com filme de polietileno e sem cobertura apresentaram maiores taxas de sobrevivência de M. phaseolina e o solo coberto com palhada de P. glaucum a menor taxa. Maior sobrevivência foi observada no solo não esterilizado.

As unidades experimentais constituíram-se de 400 cm³ de amostras de solo, colocadas em câmaras feitas de tubos de PVC, com 10 cm de diâmetro e 5 cm de altura, contendo, cada câmara, uma lâmina de resina trocadora de cátions ácido forte (modelo CR61CZR IONICS, Inc como dreno de Zn, nas dimensões de 2,0 x 5,0 cm, colocada à profundidade de 2,5 cm no meio da câmara. As amostras, umedecidas até a capacidade de campo, foram incubadas por um período de 15 dias à temperatura de 24 ± 4ºC. Após esse período, as lâminas foram retiradas, realizando-se a extração do Zn adsorvido às lâminas de resina. O pH do solo demonstrou ser fator de grande importância no controle do fluxo difusivo do Zn, acarretando-lhe grande diminuição quando da elevação de pH. De modo geral, o fluxo difusivo de Zn foi menor com o aumento do teor de argila do solo. O fluxo difusivo de Zn foi maior, nos três solos, quando a fonte utilizada foi ZnCl2.

    The magnetic mineral content in the fine sediment of Bengawan Solo River is discussed. The fine sediment is obtained on the upper part of the tributary of Bengawan Solo River. Magnetic minerals are separated using permanent magnets. Furthermore the magnetic minerals are overnight dried using oven at 100°C. FTIR characterization indicate that the magnetic minerals in the fine sediment of Bengawan Solo River have the same characteristics as minerals in Cilacap and Purwokerto areas. Magnetic minerals are estimated to form at wave number k = 569.03 cm-1. This hematite content increase to 70.67% after anealling treatment at 600°C for 4 hours in atmosphere condition. This result is interesting because the heating process increases the hematite content. Within results, the magnetic properties of the sample will change.

As diferenças entre os materiais de origem e as classes de relevo e sua influência na formação dos solos têm constituído o tema principal dos estudos de genêse realizados no Rio de Janeiro. Este trabalho teve como objetivo avaliar o comportamento das formas extraíveis de ferro, Feo, Fed e Fes, e as relações entre elas em função do grau de pedogênese dos solos. Para estes solos, as formas de ferro e relações Fed/Fes e Feo/Fed expressaram variações na mineralogia do material de origem, grau de intemperismo dos solos e do material formador, ou classe de drenagem, mais do que a intensidade de pedogênese. Assim, as formas extraíveis de Fe e respectivas relações para avaliar o grau de pedogênese, nos solos do Rio de Janeiro, requerem uma interpretação conjunta das demais propriedades do solo, com ênfase para a morfologia e classes de drenagem.

    Full Text Available A biomassa microbiana assume papel importante na reciclagem do fósforo em solos tropicais e subtropicais. Este trabalho teve por objetivo quantificar o teor de fósforo armazenado na biomassa microbiana em solos submetidos a diferentes métodos de preparo e sucessões de culturas. Para tal, foram utilizados quatro experimentos, instalados em diferentes locais no Rio Grande do Sul a partir de 1979, envolvendo métodos de preparo do solo e sucessões de culturas. Em 1997, coletaram-se amostras de solos nos sistemas plantio direto e cultivo convencional, com várias sucessões de culturas, em três camadas de solo. O fósforo acumulado na biomassa microbiana foi determinado por fumigação-extração. O fósforo na biomassa não diferiu entre os métodos de preparo do solo no Latossolo Vermelho Distroférrico típico, mas foi maior no sistema plantio direto em comparação ao cultivo convencional no Latossolo Vermelho Distrófico típico e Argissolo Vermelho Distrófico típico. O cultivo de diferentes plantas anuais não afetou os teores de fósforo microbiano. O fluxo anual de P através da biomassa microbiana variou de 8 a 22 mg dm-3 ano-1 e, no Argissolo Vermelho Distrófico típico, foi maior no sistema plantio direto do que no cultivo convencional.

    Full Text Available BACKGROUND Unlike many other countries, only 19% of physicians remain independent or solo practitioners in the United States. This study seeks to determine if entry barriers to solo practice exist in physician services markets with a predominantly suburban patient base. Any entry barrier will play a critical role in a wide variety of competition and income-related issues in these markets. MATERIALS AND METHODS This study hypothesizes that substantial deterrence to entry is present in suburban settings where physician competition is typically much less than metropolitan areas. Information about their competitive position was obtained from solo primary care physicians (PCPs and specialists in southern New Jersey municipalities. Two-sample t - tests (α =0.05 ascertained whether the means differences of these two groups are statistically significant for the population from which they were sampled. Regression coefficients were computed for the magnitude of differences in barrier impact between samples. RESULTS Adapting the Orr model, E = ß0 e ß 1 (πp -π* e ß 2 Q . S ß 3 µ, to this study allowed us to estimate the overall height of entry barriers to suburban solo practice. The study finds that entry barriers tend to have moderate effects on PCPs, with the exception of legal and regulatory compliance which are just as burdensome to specialists. Risk and insurance, capital, advertising, research and development (R & D as well as market concentration are far more challenging to solo specialists mainly due to overuse of already costly tests, procedures, and medications by specialists for "defensive medicine," and heavy reliance on specialists by PCPs. Labor costs are associated with several barriers. CONCLUSION Despite their declining population, market entry (and presumably survival of solo physicians is not as straightforward of a phenomenon as conjectural and anecdotal evidence might suggest. Medical specialty offers an explanatory variable

    Full Text Available As substâncias húmicas (SH representam o principal reservatório de carbono orgânico total do solo (COT e sua partição entre diferentes frações de solubilidade em meio alcalino ou ácido pode guardar relação com o tipo de solo e manejo adotado. O objetivo deste trabalho foi comparar a partição das SHs, de acordo com profundidade, tipo de solo, bioma e uso do solo no Brasil. Revisou-se a literatura, incluindo teses, dissertações, artigos e resumos em anais de eventos, em busca de dados sobre o teor de COT, sua porcentagem como ácidos húmicos (AH, ácidos fúlvicos (AF e humina (HU e a razão AH/AF.

Os dados foram analisados por estatística descritiva, correlações de Spearman e análise de componentes principais (ACP. Nos Argissolos, Latossolos e Organossolos, a fração HU contribuiu com metade do COT, tendendo a diminuir em profundidade. Para Latossolos e Organossolos, a fração AF tendeu a aumentar em profundidade. Em Neossolos, a fração AH aumentou em profundidade, embora tenha diminuído em Gleissolos e Planossolos. A razão AH/AF geralmente diminui em profundidade. Pela ACP, não foi possível identificar um padrão de agrupamento das amostras em razão do tipo de bioma e uso do solo, sugerindo que a partição das SHs tem baixo potencial como indicador de efeitos do manejo ou condições ambientais, embora seja útil para discriminar processos de humificação em algumas ordens de solo.

    Geohydrologic conditions of the Municipal Solid Waste Landfill Facility (MSWLF) on the U.S. Army Air Defense Artillery Center and Fort Bliss, El Paso County, Texas, were evaluated by the U.S. Geological Survey in cooperation with the U.S. Army. The 106.03-acre MSWLF has been in operation since January 1974. The landfill contains household refuse, Post solid wastes, bulky items, grass and tree trimmings from family housing, refuse from litter cans, construction debris, classified waste (dry), dead animals, asbestos, and empty oil cans. The MSWLF, located about 1,200 feet east of the nearest occupied structure, is estimated to receive an average of approximately 56 tons of municipal solid waste per day and, at a fill rate of 1-4 acres per year, is expected to reach its capacity by the year 2004. The MSWLF is located in the Hueco Bolson, 4 miles east of the Franklin Mountains. Elevations at the MSWLF range from 3,907 to 3,937 feet above sea level. The climate at the MSWLF and vicinity is arid continental, characterized by an abundance of sunny days, high summer temperatures, relatively cool winters typical of arid areas, scanty rainfall, and very low humidity throughout the year. Average annual temperature near the MSWLF and vicinity is 63.3 degrees Fahrenheit and annual precipitation is 7.8 inches. Potential evaporation in the El Paso area was estimated to be 65 inches per year. Soils at and adjacent to the MSWLF are nearly level to gently sloping, have a fine sandy loam subsoil, and are moderately deep over caliche. The MSWLF is underlain by Hueco Bolson deposits of Tertiary age and typically are composed of unconsolidated to slightly consolidated interbedded sands, clay, silt, gravel, and caliche. Individual beds are not well defined and range in thickness from a fraction of an inch to about 100 feet. The primary source of ground water in the MSWLF area is in the deposits of the Hueco Bolson. A relatively thick vadose zone of approximately 300 feet overlies the

    2007-10-01

    A preliminary study and main experiment tested the hypothesis that racial solo status (being the only member of one's race in a group) increases racial self-construal among African Americans. The preliminary study showed that African American men and women reported greater collectivist (i.e., group-based) over individualist self-construal under solo compared to nonsolo status, whereas Whites did not. The main experiment showed that the increased collectivism among African American solo women appears to be strongly reflected in racial identity becoming a salient aspect of self-construal. African American participants were also more likely than Whites to perceive that their anticipated performance would be generalized to their race, to feel like representatives of their race, and to show greater performance apprehension (indirectly evidenced by increased self-handicapping) when in racial solo status. The implications of solo status for African Americans in evaluative situations (such as academic testing sessions) are discussed. 2007 APA

    The Cerro Solo ore deposit was selected by the CNEA to invest in an assessment project because of their promising grade and amount of known and potential resources, significant to Argentina's uranium requirements. The deposit, which is located in the central region of the Chubut Province, belongs to the sandstone type and is hosted by the cretaceous Chubut Group. Technical studies carried out forecast an important growth of nuclear capacity to meet Argentina's energy requirements in the first two decades of of the the next century. To be in position to confront the challenge presented by increasing uranium resources to fuel the nuclear powers plants it is very important, as a first step, to improve the geological knowledge of uranium favorability in the country. The preliminary results of the Cerro Solo project indicate that the eastern slope of the Pichinan hills is a promising area for development of uranium resources, increasing the favorability of the San Jorge Basin in order to allow contributing to meet future uranium requirements. The Cerro Solo Project was planned in a sequential manner, as a multidisciplinary effort which includes studies on: geologic setting of mineralization, resource estimates, costs of mining and milling methods, economic analysis and environmental impact research. Among the mining methods, studies include the alternative of the in-situ leaching technology, which is becoming a low producing cost interesting possibility. (Author)

    Texas (TX), U.S., is surrounded by areas prone to wildfire and agricultural burning (collectively referred to as biomass burning) and smoke plumes from these fires can be driven by meteorological conditions to travel across the state, depositing a variety of pollutants. These pollutants include aerosols, which exert several negative effects on the environment and human health and are especially harmful when deposited in highly-populated metropolitan areas. In El Paso, TX, elevated atmospheric concentrations of ozone and PM 2.5 occur when aerosol-carrying biomass burning smoke plumes reach the city. One such pollution episode was identified by El Paso UTEP (CAMS 12) ground monitor on July 16th, 2016. To identify the sources of this pollution episode, this study utilized NASA Earth Observations including Terra MODIS aerosol optical depth (AOD) and CALIPSO CALIOP calibrated and geo-located vertical profiles of aerosols and clouds to perform 3-D spatial temporal plume tracking. Thermal anomaly maps from Suomi NPP VIIRS were also used in conjunction with NOAA Hybrid Single Particle Lagrangian Integrated Trajectory (HYSPLIT) Model trajectories. Results from these analyses indicated several potential source wildfires that could have contributed to the elevated pollutant concentration levels, of which the School and Black Range Complex Fires in the Gila Wilderness of New Mexico, U.S. and agricultural biomass burning in Guaymas, Mexico were identified as the main contributors. 3-D aerosol transport maps produced using Terra MODIS AOD data for the exceedance date and CALIPSO CALIOP vertical profiles for a date leading up to the exceedance further validated this result. The results of this study can be replicated for other dates in other locations where similar elevated pollutant concentration levels are observed via ground monitors. This analysis, which combined in situ data, trajectory models and remote sensing data, proves itself a valuable tool for studying air pollution

    A methodology is presented to determine the optimal location of the capacitor banks in shunt for distribution networks. The proposed tool allows knowing the bank type to install (fixed, disconnect able or of pass), as well as the electrical parameters of the feeder and the economic benefit that the banks of capacitors represent, with a minimum of input data. Its development in a spreadsheet allows the analysis of numerous alternatives in an easy way. The method is based on that the structure of the feeders of distribution is, generally, of radial type, with which, and by means of an iterative process, the optimal location of the capacitor banks in shunt is looked for. The type of bank is determined based of the demand, as well as the number of steps. The results of the analysis in feeders of the network of the central area are shown. [Spanish] Se presenta una metodologia para determinar la localizacion optima de los bancos de capacitores en derivacion en redes de distribucion. La herramienta propuesta permite conocer el tipo de banco a instalar (fijo, desconcectable o de paso), asi como los parametros electricos del alimentador y el beneficio economico que representan los bancos de capacitores, con un minimo de datos de entrada. Su desarrollo en una hoja de calculo permite el analisis de numerosas alternativas de manera facil. El metodo se basa en que la estructura de los alimentadores de distribucion es, por lo general, de tipo radial, con lo cual, y por medio de un proceso iterativo, se busca la localizacion optima de los bancos de capacitores en derivacion. Se determina el tipo de banco en funcion de la demanda, asi como el numero de pasos. Se muestran resultados del analisis en alimentadores de la red del area central.

    Full Text Available A influência da Trifluralina 600 CE sobre a atividade microbiana e taxa de liberação de CO2 foi estudada com amostras de solos da Unidade de Mapeamento São Pedro e Cruz Alta, incubados a 80% da capacidade de campo ou saturados, com tratamentos equivalendo a 2 e 4 litros por hectare, com cinco repetições, durante 140 dias. A cada sete dias foram efetuadas titulações de CO2 liberado. Posteriormente foi executado bioensaio com Sorghum bicolor L. Moench para análise da persistência do produto no solo. O herbicida nas dosagens usadas não afetou a atividade microbiana. A persistência do herbicida mostrou diferença significativa entre plântulas anormais para os dois solos em capacidade de campo, o mesmo não ocorrendo quando a germinação foi em solos saturados.

Objetivo: Comparar as medidas de velocidade autosselecionada no solo, na esteira rolante e a velocidade ideal estimada pelo número de Froude em sujeitos amputados transfemorais. Método: Primeiramente foi determinada a velocidade no solo; em seguida, realizou-se o teste na esteira, e a velocidade ideal foi estimada a partir dos dados antropométricos. Todos os sujeitos utilizavam joelho hidráulico e pé em fibra de carbono. Para comparação entre as velocidades foi realizada ANOVA de duas vias. Resultados: A velocidade autosselecionada na esteira foi menor (22% do que no solo. Tanto a velocidade autosselecionada na esteira como a do solo foram 44% e 22% menores do que a velocidade ideal estimada, respectivamente. Conclusão: As velocidades analisadas no presente estudo foram diferentes, provavelmente, devido à variação dos parâmetros cinemáticos.

    Full Text Available O objetivo deste trabalho foi avaliar a relação entre a estrutura anatômica das raízes de milho e os atributos físicos de solo submetido a diferentes graus de compactação. O estudo foi realizado em campo, no Município de Dourados, MS, em Latossolo Vermelho distroférrico, textura muito argilosa. O delineamento experimental foi o de blocos ao acaso, com cinco repetições. O solo utilizado apresentava histórico de oito anos com plantio direto. A compactação adicional do solo foi realizada por meio de tráfego com trator, com uma (PDc1, duas (PDc2, quatro (PDc4 e seis passadas (PDc6 sucessivas, sobre toda a área da parcela. Houve aumento na razão entre o córtex e o cilindro vascular da raiz com o aumento na compactação do solo. Essa razão correlacionou-se negativamente com a macroporosidade e positivamente com a densidade do solo e com a resistência do solo à penetração. O grau de compactação afeta a anatomia radicular do milho, e a resistência do solo à penetração é o indicador físico que melhor expressa esse efeito.The objective of this work was to evaluate the relationship between maize root anatomy and physical attributes of soil subjected to levels of compaction. The experiment was carried out in field conditions, in Dourados, Mato Grosso do Sul state, Brazil, in a clayed Latossolo Vermelho (Rhodic Acrustox. A randomized complete block design was used, with five replicates. The soil was cultivated for eight years under no-tillage. The additional compaction of the soil was done by tractor traffic in one (PDc1, two (PDc2, four (PDc4 and six successive passes (PDc6, in the entire area of the experimental plots. Ratio between the cortex and vascular cylinder of the root increased with soil compaction. This ratio was negatively correlated to macroporosity, and positively to soil density and soil penetration resistance. Soil compaction level affects the anatomy of maize roots, and its penetration resistance is the best

    Full Text Available Apesar de ainda existirem ecossistemas altomontanos no Paraná em excelente estado de conservação, iminentes ameaças antrópicas e a fragilidade desses ambientes têm sido motivos de preocupação. Este trabalho teve os seguintes objetivos: caracterizar solos de área representativa dos campos e florestas altomontanas ocorrentes na Serra da Igreja; apontar quais os possíveis fatores pedológicos que resultam nessas diferentes fitotipias; e caracterizar algumas das suas funcionalidades ambientais (estoque de C e de água. Os principais solos encontrados nos campos foram Organossolos Fólicos fíbricos/sápricos (líticos e típicos e Organossolos Háplicos fíbricos/sápricos (típicos e térricos e, nas florestas altomontanas, Gleissolos Háplicos alíticos típicos. Ambas as classes são de solos distróficos, extremamente ácidos, com alta saturação por Al trocável e altos teores de C orgânico total. A distribuição das florestas altomontanas está fortemente controlada por vales e colos de cumeeiras, os quais estão sujeitos a processos morfogenéticos que resultam em solos com horizontes minerais. Já os campos estão estabelecidos em topos, onde processos pedogenéticos promoveram espessamento de horizontes hísticos, os quais, em função de suas características intrínsecas, aliadas aos fortes ventos, parecem conter com sucesso o avanço da floresta sobre o campo. Os estoques de C por unidade de área nos solos dos campos são superiores aos dos solos das florestas altomontanas, sendo ambos considerados altos quando comparados aos dados de outros ecossistemas, sendo duas a três vezes maiores do que os encontrados em solos de ecossistemas de altitudes mais baixas na mesma latitude. Também foi constatada alta capacidade de retenção hídrica devido à porosidade total verificada nos horizontes hísticos, os quais têm o potencial de reter em média 12 vezes seu volume em água.

    Full Text Available Há restrições ao crescimento de plantas em condições de inundação do solo, o que limita a sua exploração agrícola a poucas espécies. A soja pode ser uma alternativa, pela alta capacidade adaptativa a estas condições. O objetivo deste trabalho foi identificar as formas de adaptação da soja à inundação do solo, e estabelecer a melhor estratégia para fornecimento de N em solos inundados. Foi conduzido um experimento em casa de vegetação, na Faculdade de Agronomia da Universidade Federal do Rio Grande do Sul (UFRGS, de setembro a novembro de 1998. Foram testadas duas cultivares de soja (FT-Abyara e BR 4 cultivadas sob dois regimes hídricos (inundação e capacidade de campo e duas estratégias de fornecimento de N (inoculação e N mineral. Manteve-se a soja sob inundação do estádio V2 até V5 (21 dias. A soja apresentou mecanismos que permitem sua adaptação a condições de hipoxia geradas pela inundação do solo. Houve redução nos teores de N, K, Mg e Mn, e aumento nos teores de Fe nas folhas, quando da inundação. Existiram diferenças entre cultivares em solo inundado, destacando-se a cultivar FT-Abyara, pela maior adaptação. O diâmetro do caule sob a lâmina de água foi a característica mais importante na diferenciação de cultivares com vistas a tolerância à inundação. A melhor estratégia para fornecimento de N em condições de solo inundado foi a aplicação de N mineral em cobertura. Porém, mesmo em solo inundado ocorreu nodulação em soja.

    Full Text Available A busca de sistemas de manejo do solo como aqueles que integram lavoura e pecuária, visando à recuperação e, ou, manutenção da qualidade do solo, é fundamental para o manejo sustentável da agropecuária. A hipótese deste estudo é que o uso do solo em sistema de integração lavoura-pecuária melhora as suas propriedades físicas, contribuindo dessa maneira para uma exploração agrícola sustentável do solo na região sudoeste do Cerrado. O objetivo deste trabalho foi verificar a influência de diferentes sistemas de manejo em algumas propriedades físicas de um solo na região dos Cerrados. O solo é classificado como Latossolo Vermelho distrófico, na região do Cerrado, onde foram avaliados os seguintes sistemas de manejo: solo sob vegetação natural; solo com implantação de lavoura de soja durante um ano e seguido de três anos de pastagens; solo com implantação de lavoura de soja durante quatro anos, seguidos por quatro anos de pastagem; solo com lavoura de soja contínua em sistema de plantio direto; e solo com pastagem continuamente. Foram avaliadas a densidade do solo, a resistência do solo à penetração e a estabilidade dos agregados em água, no período de 1995 a 2006. O uso do solo com a forrageira BRACHIARIA DECUMBENS como pastagem contínua proporcionou menor impacto nas propriedades físicas do solo, em relação aos manejos com integração lavoura-pecuária e lavoura contínua.

    Milton César Costa Campos

    2010-12-01

    Full Text Available A influência nociva dos íons metálicos no ecossistema via contaminação das águas, dos solos e consequentemente dos organismos vivos nos últimos anos têm despertado grande interesse na compreensão do comportamento e dos mecanismos de transporte dos metais no solo e em outros compartimentos do ambiente. Sendo assim, o objetivo desta revisão foi discutir aspectos do solo e suas relações com o comportamento dos metais pesados e seus possíveis riscos de lixiviação. É sabido que de maneira geral, os metais pesados comportam-se no solo dependendo dos seguintes atributos, pH, quantidade de matéria orgânica, potencial redox, tipologia e quantidade da argila. Por outro lado, em ecossistemas tropicais, onde predominam solos altamente intemperizados, a movimentação dos metais pesados no perfil do solo é governada principalmente pelo regime hídrico, capacidade de retenção do solo e posição do solo na paisagem. Apesar da importância do tema, os estudos ainda são bastante incipientes e preliminares, necessitando de investigações mais aprofundadas que enfatize as particularidades de cada elemento e suas interações no solo em ecossistemas tropicais, possibilitando o estabelecimento de ações preventivas para evitar a contaminação dos recursos naturais.

  18. Testosterone-dependency of male solo song in a duetting songbird--evidence from females.

    Voigt, Cornelia; Leitner, Stefan

    2013-01-01

    For male songbirds of the temperate zone there is a tight link between seasonal song behaviour and circulating testosterone levels. Such a relationship does not seem to hold for tropical species where singing can occur year-round and breeding seasons are often extended. White-browed sparrow weavers (Plocepasser mahali) are cooperatively breeding songbirds with a dominant breeding pair and male and female subordinates found in eastern and southern Africa. Each group defends an all-purpose territory year-round. While all group members sing duets and choruses, the most dominant male additionally sings a solo song that comprises a distinct and large syllable repertoire. Previous studies suggested this type of song being associated with reproduction but failed to support a relationship with males' circulating testosterone levels. The present study aimed to investigate the steroid hormone sensitivity of the solo song in more detail. We found that dominant males had significantly higher circulating testosterone levels than subordinates during the early and late breeding seasons. No changes in solo song characteristics were found between both time points. Further, experimental implantation of captive adult females with exogenous testosterone induced solo singing within one week of treatment. Such females produced male-typical song regarding overall structure and syllable composition. Sex differences existed, however, concerning singing activity, repertoire size and temporal organisation of song. These results suggest that solo singing in white-browed sparrow weavers is under the control of gonadal steroid hormones. Moreover, the behaviour is not male-specific but can be activated in females under certain conditions. Copyright © 2012 Elsevier Inc. All rights reserved.

    To compare stentless Freedom Solo and stented Trifecta aortic bioprostheses regarding hemodynamic profile, left ventricular mass regression, early and late postoperative outcomes and survival. Longitudinal cohort study of consecutive patients undergoing aortic valve replacement (from 2009 to 2016) with either Freedom Solo or Trifecta at one centre. Local databases and national records were queried. Postoperative echocardiography (3-6 months) was obtained for hemodynamic profile (mean transprosthetic gradient and effective orifice area) and left ventricle mass determination. After propensity score matching (21 covariates), Kaplan-Meier analysis and cumulative incidence analysis were performed for survival and combined outcome of structural valve deterioration and endocarditis, respectively. Hemodynamics and left ventricle mass regression were assessed by a mixed- -effects model including propensity score as a covariate. From a total sample of 397 Freedom Solo and 525 Trifecta patients with a median follow-up time of 4.0 (2.2- 6.0) and 2.4 (1.4-3.7) years, respectively, a matched sample of 329 pairs was obtained. Well-balanced matched groups showed no difference in survival (hazard ratio=1.04, 95% confidence interval=0.69-1.56) or cumulative hazards of combined outcome (subhazard ratio=0.54, 95% confidence interval=0.21-1.39). Although Trifecta showed improved hemodynamic profile compared to Freedom Solo, no differences were found in left ventricle mass regression. Trifecta has a slightly improved hemodynamic profile compared to Freedom Solo but this does not translate into differences in the extent of mass regression, postoperative outcomes or survival, which were good and comparable for both bioprostheses. Long-term follow-up is needed for comparisons with older models of bioprostheses.

    Advancement in both surgical technique and medical equipment has enabled solo surgery. ViKY ® Endoscope Positioning System (ViKY ® ) is a robotic system that remotely controls an endoscope and provides direct vision control to the surgeon. Here, we report our experience with ViKY ® -assisted solo surgery. We retrospectively examined 25 cases of solo surgery TAPP with ViKY ® . ViKY ® was setup by the surgeon alone, and the setup duration was determined as the time at which the side rail was positioned and that when the endoscope was installed. For assessing the control unit, the number of false movements was counted. We compared the operative results between ViKY ® -assisted solo surgery TAPP and the conventional method with an assistant. The average time to set up ViKY ® was 7.9 min. The average number of commands for ViKY ® during surgery was 98.3, and the average number of errors and no response of control unit was 7.9. The mean duration of surgery was 136 min for the ViKY ® group, including the setup time, and 117 min for the conventional method. No case required an assistant during the operation. There was also no difference between the two groups with regard to postoperative complications and the rate of recurrence. ViKY ® proved reliable in recognizing orders with very few failures, and the operations were performed safely and were comparable to the conventional operations with assistants. Solo surgery with ViKY ® was beneficial in this clinical evaluation.

    Full Text Available Weed control program should be environmentally benign and cost-effective so that reduced herbicide use can help meet these goals. Field trials were conducted to assess the bio-economic and qualitative impact of reduced doses (25 and 50% of label dose of a postemergence pyrimidinyloxybenzoic acid herbicide (bispyribac-sodium applied alone or in combination with multipurpose tree (eucalyptus Eucalyptus camaldulensis Dehnh., mango Mangifera indica L., and mulberry Morus alba L. water extracts in direct seeded rice (Oryza sativa L. fields. The label dose of bispyribac-sodium and penoxsulam along with weed control were included for comparison. Tank mixing of multipurpose tree water extracts with reduced herbicide doses accounted for > 55% suppression in weed density and > 75% in dry weight; they were quite higher than those recorded for the same herbicide doses used alone. A combination of these extracts with 50% reduced dose of bispyribac-sodium improved rice yield and quality attributes similar to the label dose of this herbicide. Despite the higher net benefits associated with label herbicide dose, the maximum marginal rate of return was achieved with a tank mix of 25% label herbicide dose with multipurpose tree water extracts.Los programas de control de malezas deben ser respetuosos del medio ambiente y rentables, y la reducción del uso de herbicidas puede ayudar a cumplir estas metas.

    Full Text Available A viabilidade de escleródios de Sclerotinia sclerotiorum foi avaliada durante oito meses em três solos de Cerrado cultivados. Escleródios produzidos "in vitro", mantidos em invólucros de náilon perfurados, foram enterrados a 5 cm de profundidade, em solos previamente fumigados ou não fumigados com brometo de metila. Após 10 dias de incubação, os escleródios foram examinados quanto à viabilidade e a presença de fungos antagônicos. A viabilidade foi estimada através do número de escleródios germinados 7 dias após plaqueamento em meio semi seletivo Neon-S. A viabilidade dos escleródios variou com o solo de Cerrado. Escleródios incubados em solos não fumigados com brometo de metila apresentaram menor viabilidade e maior presença de fungos antagônicos, indicando que estes solos contêm elementos supressivos de origem biológica. A viabilidade dos escleródios foi relacionada negativamente com a população de alguns microorganismos de solo. Nos tratamentos de maior incidência de Trichoderma spp. observou-se menor viabilidade de escleródios e solos fumigados suprimiram fortemente a ocorrência deste antagonista.

    Full Text Available A distribuição e a dissipação dos herbicidas nos solos são processos dinâmicos e únicos para cada relação solo-herbicida. Neste trabalho, a meia-vida do diuron foi determinada em cinco solos (Latossolo Vermelho Amarelo, Latossolo Vermelho e Latossolo Amarelo, com diferentes valores de pH. As concentrações do diuron foram determinadas em amostras dos referidos solos coletadas em oito épocas (1, 8, 15, 22, 36, 66, 96 e 156 dias após a aplicação do herbicida na dose 3,0kg ha-1. Em uma parte dessas amostras, foi feita a quantificação do diuron por cromatografia líquida de alta eficiência e, na outra parte, os testes biológicos, visando à confirmação dos resultados das análises cromatográficas. Constatou-se que a persistência do diuron é dependente dos atributos físicos e químicos dos solos. Todavia, a correção do pH do solo favoreceu apenas a degradação do herbicida em solos arenosos com baixo teor de matéria orgânica. A meia-vida do diuron nos solos estudados variou de 40 a 91 após a sua aplicação, sendo maior no solo com maior teor de matéria orgânica. Esses resultados foram confirmados pelos testes biológicos que se mostraram eficientes e complementares às análises cromatográficas.

    LuxR solo transcriptional regulators contain both an autoinducer binding domain (ABD; N-terminal) and a DNA binding Helix-Turn-Helix domain (HTH; C-terminal), but are not associated with a cognate N-acyl homoserine lactone (AHL) synthase coding gene in the same genome. Although a few LuxR solos have been characterized, their distributions as well as their role in bacterial signal perception and other processes are poorly understood. In this study we have carried out a systematic survey of distribution of all ABD containing LuxR transcriptional regulators (QS domain LuxRs) available in the InterPro database (IPR005143), and identified those lacking a cognate AHL synthase. These LuxR solos were then analyzed regarding their taxonomical distribution, predicted functions of neighboring genes and the presence of complete AHL-QS systems in the genomes that carry them. Our analyses reveal the presence of one or multiple predicted LuxR solos in many proteobacterial genomes carrying QS domain LuxRs, some of them harboring genes for one or more AHL-QS circuits. The presence of LuxR solos in bacteria occupying diverse environments suggests potential ecological functions for these proteins beyond AHL and interkingdom signaling. Based on gene context and the conservation levels of invariant amino acids of ABD, we have classified LuxR solos into functionally meaningful groups or putative orthologs. Surprisingly, putative LuxR solos were also found in a few non-proteobacterial genomes which are not known to carry AHL-QS systems. Multiple predicted LuxR solos in the same genome appeared to have different levels of conservation of invariant amino acid residues of ABD questioning their binding to AHLs. In summary, this study provides a detailed overview of distribution of LuxR solos and their probable roles in bacteria with genome sequence information. PMID:25759807

    With DNA microarrays, we identified a gene, termed Solo, that is downregulated in the cerebellum of Purkinje cell degeneration mutant mice. Solo is a mouse homologue of rat Trio8-one of multiple Trio isoforms recently identified in rat brain. Solo/Trio8 contains N-terminal sec14-like and spectrin-like repeat domains followed by a single guanine nucleotide exchange factor 1 (GEF1) domain, but it lacks the C-terminal GEF2, immunoglobulin-like, and kinase domains that are typical of Trio. Solo/Trio8 is predominantly expressed in Purkinje neurons of the mouse brain, and expression begins following birth and increases during Purkinje neuron maturation. We identified a novel C-terminal membrane-anchoring domain in Solo/Trio8 that is required for enhanced green fluorescent protein-Solo/Trio8 localization to early endosomes (positive for both early-endosome antigen 1 [EEA1] and Rab5) in COS-7 cells and primary cultured neurons. Solo/Trio8 overexpression in COS-7 cells augmented the EEA1-positive early-endosome pool, and this effect was abolished via mutation and inactivation of the GEF domain or deletion of the C-terminal membrane-anchoring domain. Moreover, primary cultured neurons transfected with Solo/Trio8 showed increased neurite elongation that was dependent on these domains. These results suggest that Solo/Trio8 acts as an early-endosome-specific upstream activator of Rho family GTPases for neurite elongation of developing Purkinje neurons.

    LuxR solo transcriptional regulators contain both an autoinducer binding domain (ABD; N-terminal) and a DNA binding Helix-Turn-Helix domain (HTH; C-terminal), but are not associated with a cognate N-acyl homoserine lactone (AHL) synthase coding gene in the same genome. Although a few LuxR solos have been characterized, their distributions as well as their role in bacterial signal perception and other processes are poorly understood. In this study we have carried out a systematic survey of distribution of all ABD containing LuxR transcriptional regulators (QS domain LuxRs) available in the InterPro database (IPR005143), and identified those lacking a cognate AHL synthase. These LuxR solos were then analyzed regarding their taxonomical distribution, predicted functions of neighboring genes and the presence of complete AHL-QS systems in the genomes that carry them. Our analyses reveal the presence of one or multiple predicted LuxR solos in many proteobacterial genomes carrying QS domain LuxRs, some of them harboring genes for one or more AHL-QS circuits. The presence of LuxR solos in bacteria occupying diverse environments suggests potential ecological functions for these proteins beyond AHL and interkingdom signaling. Based on gene context and the conservation levels of invariant amino acids of ABD, we have classified LuxR solos into functionally meaningful groups or putative orthologs. Surprisingly, putative LuxR solos were also found in a few non-proteobacterial genomes which are not known to carry AHL-QS systems. Multiple predicted LuxR solos in the same genome appeared to have different levels of conservation of invariant amino acid residues of ABD questioning their binding to AHLs. In summary, this study provides a detailed overview of distribution of LuxR solos and their probable roles in bacteria with genome sequence information.

    Full Text Available Este trabalho objetivou avaliar a migração e a modificação de frações de Cu e Zn em solos de vinhedos. Em outubro de 2010 foram selecionados, em Água Doce (SC três vinhedos com idades crescentes e uma área de campo natural com o objetivo de determinar o teor natural dos elementos no solo. Amostras de solo dos vinhedos e campo natural foram coletadas em camadas estratificadas e analisadas. Nas amostras foram realizados o fracionamento químico e a extração de Cu e Zn por EDTA e pelo método 3050B da USEPA. O Cu e o Zn foram acumulados nas camadas mais superficiais dos solos dos vinhedos e maiores concentrações foram observadas no vinhedo com maior idade. A maior parte do Cu e do Zn nos solos dos vinhedos foi distribuída na fração residual que possui baixa mobilidade geoquímica porém nas camadas mais superficiais do solo do vinhedo com maior idade constatou-se aumento do teor de Cu ligado à matéria orgânica do solo e nas camadas mais profundas, ligado aos minerais. A maior parte do Zn no solo dos vinhedos foi distribuída na fração residual e ligada aos minerais; a fração residual possui baixa mobilidade no solo mas pode ser disponível para as plantas e causar toxidez.

    Full Text Available Na região amazônica, pastagens formadas e conduzidas de forma inadequada perdem a produtividade durante os primeiros anos em razão de superpastejo, ausência de adubação e de manutenção e emprego de espécies inadequadas para as condições edafoflorísticas da região. O objetivo deste estudo foi quantificar as modificações ocasionadas por diferentes sistemas de manejo nos atributos físicos de um Latossolo Vermelho-Amarelo (LVA, sob pastagem degradada no Estado de Rondônia, RO. Os sistemas de manejo utilizados nos tratamentos foram: T = testemunha; G = gradagem + NPK + micronutrientes; H = herbicida + NK + micronutrientes; A = plantio direto de arroz + NPK + micronutrientes; e S = plantio direto de soja + NPK + micronutrientes. O delineamento experimental foi em blocos ao acaso com quatro repetições. Para avaliar os tratamentos, amostras com estrutura indeformada foram coletadas em três profundidades (0-0,10; 0,10-0,20 e 0,20-0,30 m para determinar a curva de retenção da água no solo, densidade do solo, resistência do solo à penetração de raízes, macroporosidade, microporosidade, porosidade total, estimativa do intervalo hídrico ótimo (IHO, densidade máxima do solo (Dsmax e densidade relativa do solo (Dsrel. Os sistemas de manejo do solo adotados na recuperação da pastagem não proporcionaram melhorias significativas nos atributos físicos do solo, 40 meses após a implantação dos tratamentos. Em todos os sistemas de manejo, foram encontrados valores de densidade do solo acima do considerado ideal (1,40 Mg m-3 e abaixo do crítico (1,75 Mg m-3. Todos os sistemas de manejo apresentaram valores de densidade do solo relativa (Dsrel acima do valor adotado como crítico (Dsrel = 86 %, exceto no sistema em que foi realizado o preparo do solo na profundidade de 0-0,10 m. A qualidade física do solo, avaliada pelo IHO, diminuiu com o aumento da profundidade do solo.

    Full Text Available The present study sought to observe the behavior of soils in natural state and in mixtures, in different ratios, with the industrial solid residue called whitewash mud. The work was conducted with samples of typical soils from the region of Alagoinhas, Bahia-Brazil. Wet chemical analysis and atomic absorption spectrophotometry were used in order to obtain the classification of the industrial solid residue. Solubilization and leaching tests were performed and X-ray diffraction and electron microscopy techniques were carried out. The results showed that the whitewash mud was classified as non-inert, but with great capacity of heavy metal retention largely owed to the kaolinite and goethite presence in the clay fraction of the soils, making it difficult to have heavy metals readily available for exchange.O presente estudo buscou observar o comportamento de solos em seu estado natural e em misturas, em diferentes teores, com o resíduo sólido industrial denominado lama-de-cal. A pesquisa foi conduzida com amostras de solos típicas da região de Alagoinhas, Bahia-Brasil. A análise química por via úmida e espectrofotometria de absorção atômica foram usadas para obter a classificação do resíduo sólido industrial. Testes de solubilização, lixiviação, analise de raios X e microscopia eletrônica de varredura foram executados. Os resultados indicaram que a lama-de-cal não é inerte, mas com grande capacidade de retenção de metais pesados, em grande parte devido à presença de caulinita e goethita na fração argila dos solos.

    Full Text Available Em ecossistemas de pastagens naturais deficientes em P disponível, a imobilização temporária do P na biomassa microbiana e sua posterior mineralização podem ser considerados mecanismo potencial de suprimento de P às plantas. O objetivo deste trabalho foi avaliar a influência da queima e do pastejo da vegetação campestre sobre a dinâmica do P no solo, com ênfase no conteúdo de P imobilizado na biomassa microbiana. Os tratamentos consistiram da associação do pastejo (presença ou ausência e da queima (ausência ou presença numa pastagem natural manejada há 13 anos com histórico de queimadas e de pastejo nas posições de relevo de encosta (Argissolo e de baixada (Planossolo. A queima e o pastejo foram arranjados em delineamento completamente casualizado com quatro repetições. Coletaram-se amostras de solo na camada de 0-10 cm em duas épocas, durante a estação de crescimento da pastagem natural, sempre logo após o pastejo. A carga animal utilizada foi calculada adotando-se uma taxa de utilização de 20-35 % da massa de forragem. Determinaram-se o teor de P armazenado na biomassa microbiana do solo, o teor de P total e o de P orgânico total. A análise estatística dos resultados foi baseada em análise de variância via testes de aleatorização. O teor de P microbiano do solo sob pastagem natural variou de 11,4 a 57,3 mg kg-1, representando, em média, 38 e 32 % do P orgânico total do solo, na primeira e na segunda coleta, respectivamente. O P imobilizado na biomassa microbiana constitui a reserva potencial de P capaz de suprir a demanda de espécies nativas nas pastagens naturais, além de ser indicador mais sensível que o teor de P orgânico total do solo para detectar as alterações promovidas pelo pastejo. O manejo das pastagens naturais com fogo diminui a amplitude do incremento de P microbiano decorrente do pastejo.

    Full Text Available Este trabalho tem por objetivo analisar a influência da quantidade de cimento, da porosidade, da umidade de moldagem e do contaminante sobre o comportamento físico de um solo argiloso artificialmente cimentado. O programa experimental consistiu em caracterizar os materiais utilizados e analisar fisicamente a mistura solo-cimento-contaminante, através de ensaios de resistência à compressão simples. O contaminante utilizado nesta pesquisa foi o resíduo borra oleosa ácida, oriundo de uma refinaria que realiza o re-processamento de óleos lubrificantes. Para a obtenção dos parâmetros de moldagem (peso específico máximo seco e umidade ótima do solo natural e das misturas solo/cimento e solo/cimento/contaminante, foram realizados ensaios de compactação com energia Proctor normal, intermediária e modificada. Os resultados, quanto à caracterização, apresentaram um material argiloso, oriundo de rochas riodacitos; quanto à resistência à compressão simples observou-se que a quantidade de cimento exerceu um efeito de acréscimo de resistência do material. Verificou-se que o aumento da massa específica aparente seca influenciou no ganho de resistência para um mesmo teor de cimento adotado, sendo que o acréscimo de resistência foi maior para teores de 20% de cimento, quando comparado com teores de 5%. Concluiu-se que a quantidade de cimento e a diminuição da porosidade ocorrida pela maior densificação influenciam em ganho de resistência e menor consumo de cimento. A variação de umidade de moldagem, mantendo-se constante o peso específico aparente seco, afetou a resistência à compressão simples do solo cimentado contaminado.

    Full Text Available Neste trabalho apresentamos o método de análise de agregados estáveis de solos, pela peneiragem lenta, em água. Em tal método seleciona-se do massa do solo uma subamostra de 25 gramas, que é empregada na determinação dos agregados do solo. Obtém-se, dêsse modo, uma distribuição de agregados estáveis em água, em várias classes de tamanhos. Como prétratamento usou-se o umedecimento lento do amostra, por meio de um atomizador, e repouso de 24 horas antes de se proceder à análise. Êste prétratamento aumentou a estabilidade dos agregados. Os resultados da agregação são apresentados como porcentagem dos agregados maiores que uma classe de tamanho tomada como base. A representação da agregação a partir do diâmetro médio compensado é um ótimo índice da agregação do solo. Vários métodos podem ser usados para representar a agregação de um solo, a partir dos resultados obtidos pela peneiragem em água. Dentre êstes, os mais recomendáveis são aquêles que se utilizam de um simples número para sua representação. Dois tipos de solos com usos variáveis foram estudados: massapê e terra-roxa-legítima.The wet-sieving method as a measure of the size distribution of water-stable aggregates, is presented. Two types of soils are studied. Twenty five grs of a sub-sample of the total mass of soil was taken. The aggregate analysis reported in this paper were made on soil samples that were dry-sieved to pass through a 7 mm sieve and be retained on a 4 mm sieve. The pretreatment of the sample showed an increase in water-stable aggregates. The samples were moisted by a fine spray with an atomizer. The results of aggregation ore presented by the selection of one single size class for comparative studies. Procedures which utilize all size fractions to express aggregation are the best method to express the results. The fraction greater than 2.000 mm of the soil studied in this paper showed a very high aggregation when in

    Full Text Available Existe a necessidade de avaliar a importância do relevo associado aos parâmetros espectrais de solos como base no mapeamento. O objetivo deste trabalho foi determinar um método de detecção de limites de solos por meio da interação de dados espectrais e formas de relevo. Foram percorridas 14 topossequências representativas de uma área de 13.000 ha próxima dos municípios de São Carlos e Araraquara, SP. As amostras foram caracterizadas pelos métodos convencionais de análise química e granulométrica. Posteriormente, foram obtidos dados espectrais de 400 a 2.500 nm. As informações do relevo foram obtidas pelo emprego de técnicas de geoprocessamento. Geraram-se o modelo digital de elevação do terreno e os mapas de declividade, de curvatura, de índice topográfico composto e de Potencial de Densidade de Drenagem. Ainda, procedeu-se à validação dos métodos pontual e espacial. Na primeira validação, os pontos classificados nas topossequências foram tomados como verdadeiros e contrastados com as informações contidas no mapa de solo pré-existente, com os dados de relevo e com os dados espectrais agrupados. Na validação em nível espacial, procuraram-se avaliar em que locais os diferentes métodos indicavam mudanças nos limites dos solos e comparar com as observações reais. Verificou-se que a análise de agrupamento com cluster evidenciou-se eficiente na discriminação das unidades de solos em topossequência, quando utilizados parâmetros espectrais do solo. Já o conjunto de parâmetros de relevo isoladamente não foi o mais adequado.

    Full Text Available Entre os métodos puramente químicos para a dosagem de cloretos no solo, tais como gravimétricos e volumétricos e os baseados em processos físico-químicos, tais como nefelométricos, colorimétricos e eletrométricos escolhemos por mais simples e exato, o eletro-titrométrico, ideado por Best (2. Foi estudada a técnica mais razoável e perfeita para a extração dos cloretos do solo e em seguida sua titulação. Como meio de extração escolhemos a água destilada, fazendo-a percolar por uma camada de solo. A relação entre solo e água foi de 1 :4. isto é, 50 gr de solo (terra fina e 200 ml de água destilada. As dosagens tornaram-se, assim, bastante exatas e a duração do eletrodo de AgCl chegou a funcionar muito bem ainda depois de 1000 titulações. Isto não aconteceria se se usasse xima suspensão grosseira de solo para proceder à titulação. Consegue-se, com essa técnica, dosar cloretos, sem dificuldades, em 50 amostras de solo por dia. Conseguimos, assim, dosar cloretos em mais de mil amostras de solo de todo o Estado de São Paulo. Vimos que, no geral, o teor em cloretos é baixo, oscilando entre 0,2 e 2 mg de Cl~ por 100 gr de solo. Em algumas baixadas, sem circulação de água, encontramos até 20 mg por 100 gr de solo. Torna-se claro, pois, não possuirmos casos de solos ricos em sais (cloretos que fossem prejudiciais à agricultura. Em muitos casos evidenciou-se grande pobresa em iônio Cl-, sendo recomendável mesmo a adição de cloretos nas adubações para verificar seus efeitos. Entre estes solos podemos citar a nossa terra-roxa-legítima.

    Objectives. To describe the health characteristics of solo grandparents raising grandchildren compared with single parents. Methods. Using the 2012 Behavioral Risk Factor Surveillance System, respondents identified as a single grandparent raising a grandchild were categorized as a solo grandparent; grandparent responses were compared with single parents. Descriptive analysis compared health characteristics of 925 solo grandparents with 7,786 single parents. Results. Compared to single parents, grandparents have a higher prevalence of physical health problems (e.g., arthritis). Both parent groups have a high prevalence of lifetime depression. A larger share of grandparents actively smoke and did no recreational physical exercise in the last month. However, grandparents appear to have better access to health services in comparison with single parents. Conclusion. Solo grandparents may be at risk for diminished physical capacity and heightened prevalence of depression. Health professionals can be an important resource to increase grandparents' physical and emotional capacities.

    Full Text Available A bananeira pode ter sua produção prejudicada se cultivada em solos com restrições físicas. O objetivo deste trabalho foi verificar se os atributos físicos de solos rasos comprometem as raízes das plantas de bananeira. O estudo foi realizado na Chapada do Apodi (CE, onde foram comparados solos com duas profundidades efetivas: raso (profundidade aproximada de 0,57 m, mais arenoso e profundo (profundidade aproximada de 1,16 m, mais argiloso e seis profundidades de coleta de solo e de raízes (0-10;10-20;20-30; 30-40; 40-50 e 50-60 cm. Nas amostras de solo, foram determinados os seguintes atributos físicos: curva de retenção de água, densidade do solo, porosidade, granulometria e densidade de partículas. A resistência do solo à penetração (RP foi avaliada no campo, utilizando-se de penetrômetro de impacto, com cinco repetições até 60 cm de profundidade. Para o estudo de raízes, as amostras foram coletadas com sonda e, por meio da análise de imagens de raízes lavadas, foram determinados: comprimento, área e volume total, e classes de diâmetro. O solo mais profundo e argiloso apresentou maior microporosidade e porosidade total, o que contribuiu para maior retenção de água. Valores de densidade do solo e de partículas foram maiores em duas camadas do solo raso, bem como a RP que atingiu o valor de 5,1 MPa. O desenvolvimento das raízes das bananeiras foi favorecido no solo profundo, no qual foram encontradas raízes mais espessas (2,2 a 6,6 mm e mais finas (0,68 a 0,79 mm, contribuindo com a sustentação das plantas e com a absorção de água e nutrientes.

    This systematic review examined the clinical and hemodynamic performance of the stentless Freedom SOLO (Sorin Group, Milan, Italy) aortic bioprosthesis. The occurrence of postoperative thrombocytopenia was also analyzed. The Freedom SOLO is safe to use in everyday practice, with short cross-clamp times, and postoperative pacemaker implantation is notably lower. Valvular gradients are low and remain stable during short-term follow-up. Thrombocytopenia is more severe than in other aortic prostheses; however, this is without clinical consequences. Within a few years, the 15-year follow-up of this bioprosthesis will be known, which will be key to evaluating its long-term durability. Copyright © 2015 The Society of Thoracic Surgeons.

    2011-05-01

    Full Text Available As one of the oldest instruments known to mankind, the flute is present in some form in nearly every culture and ethnic group in the world. However, in Western music in particular, the flute has taken its place as an important part of musical culture, both as a solo and an ensemble instrument. The flute has also undergone its most significant technological developments in Western musical culture, moving from the bone keyless flutes of the Prehistoric era to the gold and silver instruments known to performers today. During the Renaissance and Baroque periods in particular, however, the flute rose to popularity as a solo instrument and began to evolve into its modern form. New developments in the design and mechanics of the instrument drove this increased interest, which ultimately gave the flute a prominent position in music that has lasted throughout history.

    Cano, Estefanía; Schuller, Gerald; Dittmar, Christian

    2014-12-01

    We present a system for the automatic separation of solo instruments and music accompaniment in polyphonic music recordings. Our approach is based on a pitch detection front-end and a tone-based spectral estimation. We assess the plausibility of using sound separation technologies to create practice material in a music education context. To better understand the sound separation quality requirements in music education, a listening test was conducted to determine the most perceptually relevant signal distortions that need to be improved. Results from the listening test show that solo and accompaniment tracks pose different quality requirements and should be optimized differently. We propose and evaluate algorithm modifications to better understand their effects on objective perceptual quality measures. Finally, we outline possible ways of optimizing our separation approach to better suit the requirements of music education applications.

    Full Text Available A mineralogia dos óxidos de Mn é muito variada e complexa, devido ao grande número de minerais e ao conhecimento inexato de algumas de suas estruturas. Devido à escassez de trabalhos que tratam especificamente de óxidos de Mn em solos brasileiros e seu conteúdo muito elevado em alguns solos do Quadrilátero Ferrífero (MG, este estudo objetivou caracterizar a química e a mineralogia desses óxidos nos solos dessa região, estratificando-os conforme os materiais de origem e posições na paisagem. O trabalho foi desenvolvido em uma área representativa do Quadrilátero Ferrífero, referente à Área de Proteção Ambiental da Região Metropolitana de Belo Horizonte - APA Sul RMBH, com extensão de 1.625,32 km²; a amostragem foi direcionada para a caracterização de solos com elevado teor de Mn, relacionados a três materiais de origem distintos: itabiritos, dolomitos ferruginosos e serpentinitos, tendo sido incluídos ainda alguns solos provenientes de outros materiais de origem, dentro do Quadrilátero. Alguns solos do Quadrilátero Ferrífero possuem teores de Mn na fração terra fina extraordinariamente elevados, principalmente aqueles relacionados aos dolomitos ferruginosos da Formação Gandarela. Foram identificados diversos minerais de Mn na fração argila dos solos, sem quaisquer pré-tratamentos de concentração, representados por todoroquita, litioforita e, ainda, pirolusita. A influência do material de origem no contexto deste estudo foi superior àquela da posição na paisagem e grau de intemperismo de solos ricos em Mn.

    2017-07-01

    Full Text Available A alface é a hortaliça folhosa mais produzida no Brasil, onde representa grande relevância social e econômica para pequenas propriedades. No entanto, ainda há a necessidade de estudos voltados à melhoria das condições de cultivo, a qual demanda intensa quantidade de fertilizantes, degrada a estrutura física do solo e provoca desequilíbrios biológicos pela baixa rotação de culturas. Diante disso, objetivou-se através deste trabalho identificar os efeitos de coberturas vegetais sobre os atributos químicos do solo e sobre a qualidade da alface produzida em condições de clima tropical. O experimento foi instalado em região de baixa altitude, em condições de campo, em blocos casualizados em esquema fatorial, com cultivo de alface sobre resíduos de cinco coberturas vegetais de solo implantadas em três épocas diferentes. As coberturas vegetais utilizadas foram milheto, bagaço de cana-de-açúcar, mucuna-preta, capim braquiária e crotalária, semeadas em 06/02/12, 08/03/12 e 07/04/12, com manejo aos 120, 90 e 60 dias, respectivamente. Concluiu-se que, dependendo da espécie e da época em que é feita semeadura e o manejo e o manejo, as plantas de coberturas podem interferir nos atributos químicos do solo, resultando em plantas de alface de maior altura, diâmetro e massa fresca. Plantas de alface com maior diâmetro e massa de matéria seca total foram obtidas quando cultivadas sobre resíduos de mucuna-preta e capim braquiária.

    Recent advances in medical equipment and surgical techniques have enabled solo surgery, wherein a surgeon operates alone without the participation of other surgical members. However, the application of solo surgery in single-port laparoscopic surgery (SPLS) has been rarely reported. Prospectively collected databases of 60 patients who underwent solo-SPLS for appendicitis between March 2013 and June 2014 were retrospectively reviewed. Making a transumbilical incision into the peritoneal cavity was facilitated by using a Lone Star self-retaining retractor. After the establishment of a single port through the umbilicus, we installed a mechanical adjustable camera holder (Endoworld®LAP53 Holding Systems). It was anchored to the operating table rail and firmly held the laparoscope with a possibility to adjust the same as required by the operator. The operative method was identical to the SPLS appendectomy, except for the use of these instruments. The median operation time was 50 min (25-120). None of the patients required open conversion, insertion of an additional port or help of a human assistant. The median length of hospital stay for all patients was 1.0 day (range: 1-3 days). The median dosage of required intravenous analgesics (ketorolac, 0.1 mg/kg of body weight) was 0.0 ampoule (0-4). The median interval to initiation of solid diet was 1 day (1-2). The incidence of postoperative complications was 8.3% (5/60). Our results shows that solo-SPLS appendectomy could be performed without increasing operation time or postoperative complications when performed by a surgeon competent in performing SPLS appendectomy.

    2015-01-01

    Xanthomonas oryzae pv. oryzicola (Xoc) causes bacterial leaf streak (BLS) in rice, a serious bacterial disease of rice in Asia and parts of Africa. The virulence mechanisms of Xoc are not entirely clear and control measures for BLS are poorly developed. The solo LuxR proteins are widespread and shown to be involved in virulence in some plant associated bacteria (PAB). Here, we have cloned and characterized a PAB LuxR solo from Xoc, named as XocR. Mutation of xocR almost completely impaired the virulence ability of Xoc on host rice, but did not alter the ability to trigger HR (hypersensitive response, a programmed cell death) on non-host (plant) tobacco, suggesting the diversity of function of xocR in host and non-host plants. We also provide evidence to show that xocR is involved in the regulation of growth-independent cell motility in response to a yet-to-be-identified rice signal, as mutation of xocR impaired cell swimming motility of wild-type Rs105 in the presence but not absence of rice macerate. We further found that xocR regulated the transcription of two characterized virulence-associated genes (recN and trpE) in the presence of rice macerate. The promoter regions of recN and trpE possessed a potential binding motif (an imperfect pip box-like element) of XocR, raising the possibility that XocR might directly bind the promoter regions of these two genes to regulate their transcriptional activity. Our studies add a new member of PAB LuxR solos and also provide new insights into the role of PAB LuxR solo in the virulence of Xanthomonas species.

    Full Text Available RESUMO Avaliaram-se a variabilidade temporal dos sais na água de irrigação e seus efeitos sobre os solos irrigados do Projeto Vereda Grande, em Boqueirão, PB, através de amostragem aleatória estratificada em três lotes de agricultores. Foram coletadas 66 amostras de solo e 33 de água, no período de janeiro de 1987 a dezembro de 1989, sendo que a água apresentou crescente risco de salinização ao longo do tempo, com elevados níveis de sódio e cloreto - 8,6 e 10,5 mmolc.L-1, respectivamente. A presença de solos Bruno Não Cálcico e Litólicos na área de captação do manancial impede a melhoria da qualidade da água, predispondo os solos irrigados à alcalinização. Dentre as lavouras exploradas pelos irrigantes, apenas as capineiras são moderadamente tolerantes à concentração salina na zona radicular. A presença significativa de bicarbonato (1 a 3,2 mmolc.L-1 na água restringe a prática da irrigação por aspersão devido, principalmente, às condições de alta evaporação, aridez do local e toxidez específica do sódio e cloreto em plantas sensíveis.

    Full Text Available O objetivo deste trabalho foi avaliar a comunidade de formigas em sistemas envolvendo a rotação entre lavoura e pecuária, sob plantio direto, comparado a outros sistemas de manejo e com sistemas naturais da região. O estudo foi conduzido no Município de Dourados, MS, sob Argissolo Vermelho distroférrico típico, num sistema integrado lavoura-pecuária, em plantio direto, rotacionado a cada dois anos. Outros sistemas de manejo avaliados, para comparação, incluíram o sistema convencional (aração e gradagem, sistema plantio direto e pastagem cultivada continuamente com Brachiaria decumbens, além de dois fragmentos de vegetação nativa, nos biomas Cerrado e Floresta Semidecídua. A coleta de solo foi realizada no período chuvoso (safra 2009/2010, sendo as amostragens de serapilheira realizadas com a utilização de extratores do tipo mini-Winkler, seguindo o protocolo ALL (Ants of the Leaf Litter. Os resultados indicaram morfoespécies de Strumygenys sp. e Hypoponera sp. como potencial bioindicadores de qualidade do solo. O estudo demonstrou que a importância da manutenção de fragmentos florestais (Cerrado e Floresta Semidecídua e implementação de sistemas integrados, tais como lavoura-pecuária, são menos impactantes para a mesofauna de solo e contribuem para a conservação da diversidade de formigas e manutenção da qualidade do solo.

    LuxR solos are unexplored in Archaea, despite their vital role in the bacterial regulatory network. They assist bacteria in perceiving acyl homoserine lactones (AHLs) and/or non-AHLs signaling molecules for establishing intraspecies, interspecies, and interkingdom communication. In this study, we explored the potential LuxR solos of Archaea from InterPro v62.0 meta-database employing taxonomic, probable function, distribution, and evolutionary aspects to decipher their role in quorum sensing (QS). Our bioinformatics analyses showed that putative LuxR solos of Archaea shared few conserved domains with bacterial LuxR despite having less similarity within proteins. Functional characterization revealed their ability to bind various AHLs and/or non-AHLs signaling molecules that involve in QS cascades alike bacteria. Further, the phylogenetic study indicates that Archaeal LuxR solos (with less substitution per site) evolved divergently from bacteria and share distant homology along with instances of horizontal gene transfer. Moreover, Archaea possessing putative LuxR solos, exhibit the correlation between taxonomy and ecological niche despite being the inhabitant of diverse habitats like halophilic, thermophilic, barophilic, methanogenic, and chemolithotrophic. Therefore, this study would shed light in deciphering the role of the putative LuxR solos of Archaea to adapt varied habitats via multilevel communication with other organisms using QS.

  3. Latching and Declutching Control of the Solo Duck Wave-Energy Converter with Different Load Types

    2017-12-01

    Full Text Available The solo duck wave-energy converter (WEC captures power in a point absorber manner, hence it exhibits high power-capture efficiency within only a narrow bandwidth. Passive control is characterized by a unidirectional power flow, and thus its engineering implementation can be simplified. In this paper, two typical passive control strategies, latching and declutching control, are applied to the solo duck WEC to improve its power-capture performance at wave periods larger and smaller than the natural period of the WEC, respectively. Special attention is paid to the peak value of instantaneous WEC performance parameters, including the peak motion excursion, the peak power take-off (PTO moment, and the peak-to-average power ratio, when the captured power is maximized. Performance differences between the linear and coulomb loads are also investigated. Results show that both latching and declutching control can effectively improve captured power, but also incidentally increase the peak motion excursion and peak-to-average power ratio. When under latching and declutching control, the coulomb load leads to the same maximum relative capture width and peak motion excursion as the linear load, but presents smaller peak PTO moment and peak-to-average power ratio than the linear load, hence making the coulomb load the better choice for the solo duck WEC.

    In solo offshore sailing races like those of the Solitaire du Figaro, sleep must be obtained in multiple short bouts to maintain competitive performance and safety. Little is known about the amount of sleep restriction experienced at sea and the effects that fatigue from sleep loss have on sailors' performance. Therefore, we assessed sleep in sailors of yachts in the Figaro 2 Beneteau class during races and compared response times on a serial simple reaction-time test before and after races. Twelve men (professional sailors) recorded their sleep and measured their response times during one of the three single-handed races of 150, 300 and 350 nautical miles (nominally 24-50 h in duration). Total estimated sleep duration at sea indicated considerable sleep insufficiency. Response times were slower after races than before. The results suggest that professional sailors incur severe sleep loss and demonstrate marked performance impairment when competing in one- to two-day solo sailing races. Competitive performance could be improved by actively managing sleep during solo offshore sailing races.

    In order to investigate the Stirling engine implementation technology, a Solo Stirling Engine V161 cogeneration module has been installed at the Laboratory of Applied Thermodynamics of National Technical University of Athens. A special thermodynamic analysis of the engine's performance has been conducted introducing and utilizing specially designed computing codes along with the thermal balance study of the unit. Measurements were conducted under different operational conditions concerning various heat load stages of the engine, working pressure, as well as electric power production. Analysis of the experimental results has shown that the overall performance of the Stirling unit proved very promising and quite adequate for various areal applications, equally competing with other CHP systems. The performance of the unit experienced significant stability all over the operating range. The power stand ratio 0.35 differentiates Stirling cogeneration units from others that use diverging technologies significantly. The energy savings using a Stirling CHP unit, in respect to the concurrent use of a thermal and an electrical system at the same equivalent power has revealed 36.8%. -- Highlights: ► Thermodynamic analysis of an a-type Stirling engine. ► Development of generated electrical and thermal power of the m-CHP Solo Stirling Unit to engine's load comparison. ► Stirling m-CHP until heat balance analysis. ► Evaluation of the Solo Stirling V161 unit efficiency.

    Studies on female sex offending have been limited for a number of reasons, such as societal perceptions that females are incapable of engaging in such behaviors because of their role as caretakers and nurturers in society. However, over the past few decades, studies examining female sex offenders have increased, revealing that females do commit sexual offenses and differ from their male counterparts. We examined offender, victim, and offense characteristics of female sex offenders who were convicted from 1995 to 2013 ( N = 223) in Arkansas and were sentenced to serve time in prison or placed on probation. We focused on the similarities and differences of solo and co-female sex offenders because we know from previous studies that the pathway of offending can differ between solo and co-female offenders, yet few studies have exclusively compared the similarities and differences among female sex offenders. Our data were collected from offender files that included basic personal offender information, offender survey and social history, criminal history, incident reports while incarcerated, court records, police investigation reports, initial offender and victim statements (prior to offender incarceration), and probation/parole reports. We believe the results of this study will provide further insight into the types of female sex offenders as well as the possible differences between co- and solo-offenders in relation to their victim preferences, risk levels, rehabilitation amenability, and recidivism propensities.

    The quantification of salivary oxytocin (OXT) concentrations emerges as a helpful tool to assess peripheral OXT secretion at baseline and after various challenges in healthy and clinical populations. Both positive social interactions and stress are known to induce OXT secretion, but the relative influence of either of these triggers is not well delineated. Choir singing is an activity known to improve mood and to induce feelings of social closeness, and may therefore be used to investigate the effects of positive social experiences on OXT system activity. We quantified mood and salivary OXT and cortisol (CORT) concentrations before, during, and after both choir and solo singing performed in a randomized order in the same participants (repeated measures). Happiness was increased, and worry and sadness as well as salivary CORT concentrations were reduced, after both choir and solo singing. Surprisingly, salivary OXT concentrations were significantly reduced after choir singing, but did not change in response to solo singing. Salivary OXT concentrations showed high intra-individual stability, whereas salivary CORT concentrations fluctuated between days within participants. The present data indicate that the social experience of choir singing does not induce peripheral OXT secretion, as indicated by unchanged salivary OXT levels. Rather, the reduction of stress/arousal experienced during choir singing may lead to an inhibition of peripheral OXT secretion. These data are important for the interpretation of future reports on salivary OXT concentrations, and emphasize the need to strictly control for stress/arousal when designing similar experiments.

    Analysis of food security level of household is a novelty of measurement standards which usually includes regional and national levels. With household approach is expected to provide the basis of sharp food policy formulation. The purpose of this study are to identify the condition of self-sufficiency in staple foods, and to find the main factors affecting the dynamics of self-sufficiency in staple foods on farm household level in Great Solo. Using primary data from 50 farmers in the sample and secondary data in Great Solo (Surakarta city, Boyolali, Sukoharjo, Karanganyar, Wonogiri, Sragen and Klaten). Compiled panel data were analyzed with linear probability regression models to produce a good model. The results showed that farm households in Great Solo has a surplus of staple food (rice) with an average consumption rate of 96.8 kg/capita/year. This number is lower than the national rate of 136.7 kg/capita/year. The main factors affecting the level of food self-sufficiency in the farmer household level are: rice production, rice consumption, land tenure, and number of family members. Key recommendations from this study are; improvement scale of the land cultivation for rice farming and non-rice diversification consumption.

    1996-01-01

    Full Text Available O conhecimento do comportamento de herbicidas é fundamental na avaliação de sua eficácia na agricultura e na compreensão do impacto ambiental causado por estes produtos químicos. A drenagem do solo pode influir no comportamento do herbicida pois pode atuar como fator modificador de sua mobilidade, transporte, arraste superficial e infiltração no solo e consequentemente, da contaminação de águas subterrâneas. A presente pesquisa teve por objetivo verificar o efeito de um sistema de drenagem subterrâneo sobre o arraste lateral, lixiviação e contaminação do lençol freático pelo herbicida trifluralina aplicado em pré-emergência na cultura do milho. Os resultados obtidos das avaliações efetuadas na superfície do solo, na profundidade de 0 - 15 cm e na água de drenagem permitiram concluir, principalmente, que a drenagem subterrânea funciona como redutor da lixiviação superficial do herbicida, diminuindo assim os riscos de contaminação ambiental.

    In this paper we describe the application of a personal digital assistant (PDA) or pocket PC as an effective communication device to telemonitor levels of asthma triggering gases collected from a remote location under test to a workstation which has a personal computer (PC) running on Windows XP® as the operating system. The Bluetooth® features of the PDA are explored to transmit data collected by a Direct™ Sense Tox toxic gas monitor equipped with five toxic gas probes and one temperature sensor in real time, thereby making this telemonitoring system an innovative instrument in monitoring levels of asthma triggering gases in the El Paso-border metropolitan region, a region in which asthma is highly prevalent especially in children. At the workstation or fixed location these readings are displayed using a custom made, user friendly graphical user interface (GUI) developed using software tools like action scripting with Macromedia® Flash™. The growing advancement in technology and ever diminishing sizes of handheld devices encouraged us to opt for this configuration. Moreover, the PDA and toxic gas monitor were also chosen for their light weight, portability, flexibility, low cost and data collection and transmission capabilities.

    Full Text Available La interconexión y dependencia recíproca entre Derecho Comunitario y Constituciones nacionales están aceptadas en la actualidad como un lugar común en el Derecho Público europeo, resultando casi explícitas en conceptos ya acuñados como el de multilevel constítutíonalism de Pernice o el “constitucionalismo dual” de von Bogdandy. Este artículo se detiene en el análisis de las influencias y del complejo juego de relaciones entre Parlamentos Nacionales y Unión Europea, enmarcándose claramente en el nuevo constitucionalismo europeo “multinivel”. A la luz del tratado de Lisboa analiza la interdependencia entre Derecho Comunitario y Derechos nacionales en materia parlamentaria. Se adentra en el papel que los Parlamentos nacionales pueden y deben representar en el proceso de integración europea así como en la búsqueda de su mayor democratización y ofrece los elementos necesarios para valorar jurídicamente en qué medida el Tratado de Lisboa representa un paso adelante hacia la “parlamentarización” de la Unión Europea.

    Full Text Available Changes in nutrients, chlorophyll and zooplankton were followed for 11 d in a basin of the Straits of Magellan (Paso Ancho, characterized by a homogeneous water column during a spring event defined by a drastic change in wind stress and direction. Conditions hardly seemed conducive to a phytoplankton bloom. Initial conditions were characterized by SW gales, low nutrients as well as by Chaetoceros spp. and Thalassiosira spp. dominated phytoplankton. Wind switched abruptly to calm-weak northerlies by the middle of the study period, a subsurface chlorophyll peak developed and extended to the end of the study while nitrates decreased. Zooplankton was dominated by copepods, nauplii and a diverse meroplankton assemblage. Zooplankton composition was rather uniform, except for diel changes in some taxa. Gut contents of zooplankton size fractions (including Euphausia vallentini as the largest fraction were measured. Grazing rates accounted for 0.5 % of the available chlorophyll. Phytoplankton blooming may be explained by transient water stratification resulting from the relaxation of wind stress and eventual retention of the phytoplankton in the photic layer. Minor variability in zooplankton implied the existence of a permanent and distinct assemblage in a strongly homogeneous environment.

    Full Text Available Se propone un estudio sobre el fenómeno de la migración, a partir de la revisión de la condición social de los migrantes centroamericanos a su paso por México, y se exponen las violaciones hacia sus derechos humanos. Lo anterior se basa en que si bien la migración no es un hecho reciente, sí ha sufrido transformaciones en la política migratoria nacional, así como en la reconfiguración de la sociedad mexicana. Por lo tanto, ante la dinámica del fenómeno, se propone un cambio de visión que permita consolidar una cultura de respeto a los derechos humanos y adecuar el marco jurídico para lograr la máxima eficacia de la norma, admitiendo a ésta no sólo como discurso, sino en una realidad que garantice jurídicamente el bienestar social de los individuos por encima de conductas contrarias a sus derechos humanos, conjugando una aceptación y tolerancia para permitir la convivencia social armónica.

    In 2006, El Paso County, a predominantly Hispanic urban area, was affected by a flood disaster; 1,500 homes were damaged. We assessed the health impacts of the disaster upon 475 individuals whose homes were flood-damaged using mail survey data and logistic regression. Substantial proportions of individuals had one or more physical (43 %) or mental (18 %) health problem in the four months following the floods; 28 % had one or more injury or acute effect related to post-flood cleanup. Adverse event experiences, older age, and lower socioeconomic status were significantly associated with negative post-flood health outcomes in all three logistic regression models. A lack of access to healthcare, non-US citizenship, and English proficiency were significant predictors of negative outcomes in both the physical and mental health models, while Hispanic ethnicity (physical), native-birth (mental), and more serious home damage (cleanup) were significant predictors in one model each. The disaster had disproportionate negative health impacts on those who were more exposed, poorer, older, and with constrained resource-access. While a lack of US citizenship and Hispanic ethnicity were associated with higher risks, being less acculturated (i.e., English-deficient, foreign-born) may have protected against health impacts.

    process the method proposed by Giorgi (1985, involving four steps, and starting with verbal reports about living experiences to get to the understanding of the phenomenon. The results obtained indicated that, for each individual, work assumes a different meaning, a function related to his wishes and needs, transforming the work itself in an instrument for their self-actualization. The study also allowed the identification of 10 categories of meaning: 1 a means for taking part in something, belonging; 2 independence, autonomy; 3 an instrument for the transformation of society, of the organization; 4 a means for building something; 5 knowledge, enlargement; 6 a means for being useful; 7 a means for overcoming one’s limitations; 8 possibility of relating and establishing bonds with people; 9 a means for expressing knowledge and skills; 10 related to security, personal and family maintenance. These categories support the results obtained by the Meaning of Working – MOW – Research Group (1987 on the subject. It was also found out that if the individual attributes meaning to the work performed, there is a derived feeling of gratification and pleasure, which leads to the importance of studies about the Meaning of Work. From the results can benefit: 1 the professionals, since the investigations lead to questioning themselves and, therefore, to the search of a greater knowledge of their own wishes and needs, with a consequent quest for involvement in most meaningful activities; 2 the companies, which may provide an improved adjustment between organizational objectives and individual expectations, resulting in quality, synergy, and effectiveness.RESUMENEl presente artículo es el resultado de un estudio realizado con un grupo de ejecutivos, que tuvo por finalidad comprender el significado atribuido al trabajo.

    Full Text Available ABSTRACT Background: Water has a role as media of many infectious diseases. One of disease whisch is often transmitted through water is diarrhea. The quality of water consumed by the community must be fillfull for health. So, It becomes the important thing in preventing the incidence of diarrhea.  The aim of this research was to determine the relationship between the quality of well water and the incidence of diarrhea on the community living along the riverside area of Bengawan Solo. Method: This was an observational research using cross sectional design. The subjects of this research were 66 persons staying for each upstream and downstream of Bengawan Solo.The quality of well water was assessed based on the parameters for temperature, pH, Biochemical Oxygen Demand (BOD, total dissolved solid (TDS, and E. coli.  The occurrence of diarrhea was determined by interviewing. Data would be analyzed using chi-square test at 0,05 level of significance. Result: The result of this research showed that variables which had relationship (p-value<0,05 to the incidence of diarrhea were: education, income, distance of well to septictank and to river,  knowledge, attitude, practice, pH, BOD, TDS, and E. coli content.  Well water located on upstream area of Bengawan Solo containing E. coli. Person who had well water containing  E. coli  over standard had 0,17 of probability to suffer diarrhea.  The other one, well water located on downstream area of Bengawan Solo containing total dissolved solid.  Person who had well water containing E. coli and TDS over standard had 0,13 of probability to suffer diarrhea. Conclusion: well water containing E. coli is the main variable associated to the occurrence of diarrhea on upstream area of Bengawan. The content of E. coli and TDS are two variables associated to the occurrence of diarrhea on downstream area of Bengawan. Key words :   Quality of well water, Diarrhea  Incidence, community living on the riverside of

    Marcelo Elias Fraga

    Full Text Available O presente trabalho teve como objetivo avaliar a diversidade e a sucessão da família Trichocomaceae em áreas com diferentes graus de antropização, denominadas área mais impactada e área menos impactada. O estudo foi realizado no Parque Natural Municipal do Curió, Paracambi-RJ. Foram selecionadas duas áreas, com diferentes graus de alteração antrópica, sendo em cada uma destas delimitado um talhão de aproximadamente 1.000 m², sendo nestes realizadas coletas de terra e serrapilheira para a avaliação da fertilidade e da micobiota. De maneira geral, observa-se que, na área mais impactada, ocorreram os maiores valores de pH, Ca e K. Os maiores valores de serrapilheira aportada, observados nesta área, também contribuem para os maiores valores de K, elemento facilmente lixiviável no material em decomposição. Os maiores valores de Unidades Formadoras de Colônias (UFC no solo e na serrapilheira, 9 × 10(4 e 5,4 × 10(4, respectivamente, foram observados na área mais impactada. Também nesta área foram verificados os maiores valores de Ca no solo e na serrapilheira, o que sugere que esse nutriente pode estar contribuindo para o maior número de UFCs. Para a área menos impactada, os valores de UFC estiveram entre 4 × 10(4 para serrapilheira e 5 × 10(4 para o solo, não sendo observada nenhuma associação clara entre um maior número de UFCs e os teores de nutrientes no solo e/ou na serrapilheira. O número total de fungos isolados foi de 87, pertencentes a quatro gêneros e 22 espécies diferentes, sendo 16 Penicillium spp., quatro Aspergillus spp., um Paecilomyices sp. e um Trichoderma sp. Não foi observada uma clara associação entre as variáveis climáticas e o número de UFCs. O maior número de UFCs foi observado na área mais impactada tanto no solo quanto na serrapilheira. Os maiores teores de Ca quantificados nesta área sugerem que esse nutriente pode estar contribuindo para o aumento das UFCs. O genêro Penicillum

    Full Text Available Foi realizado um experimento em tubos de percolação, utilizando-se três solos, classificados como Areia Quartzosa (AQ, Latossolo Vermelho-Amarelo (LV e Latossolo Vermelho-Escuro (LE, aos quais foram incorporadas sucessivas quantidades de lodo de esgoto, totalizando uma dose correspondente a 156,0 t ha-1 (base seca, num período de incubação de 310 dias. Após este período, os solos foram tratados com água ou com soluções de sais (KCl 0,9 mol L-1; KNO3 0,9 mol L-1; K2SO4 0,3 mol L-1 e Ca(NO32 0,3 mol L-1, adicionadas em quantidade correspondente a quatro vezes a capacidade de retenção de água dos solos. No líquido percolado pela passagem das soluções salinas, foram determinadas as quantidades de Cd, Cr, Cu, Ni e Zn presentes e, no percolado obtido com a passagem de água, além dos metais anteriormente citados, foram determinadas também as quantidades de Ca2+ e Mg2+. Os resultados permitiram observar que a adição de KCl provocou o arraste de 5% do Cd adicionado via lodo aos solos LV e LE; para os outros sais utilizados e para a água, esse arraste nunca foi superior a 2% do metal pesado adicionado via lodo. A retenção de Cd, Cu, Cr e Ni aumentou com a elevação dos teores de óxidos de Fe e Al presentes nos solos. Os elevados valores de pH e o aumento no teor de matéria orgânica proporcionado pela adição de lodo refletiram também na menor mobilidade dos metais. Os sais KCl e K2SO4 aumentaram a mobilidade de alguns dos metais estudados.

    Full Text Available A aplicação de técnicas espectroscópicas que utilizam a radiação infravermelha (NIRS-Near Infrared Spectroscopy e DRIFTS-Diffuse Reflectance Fourier Transformed Spectroscopy na análise inorgânica do solo tem sido proposta desde a década de 1970, mas até os dias atuais são raros os métodos implementados rotineiramente no Brasil. Isso deve-se à dificuldade em construir modelos de calibração, por meio de métodos estatísticos multivariados, utilizando-se amostras reais de solo, de constituição complexa, que varia geograficamente e de acordo com o manejo. Por isso, os objetivos deste trabalho foram construir modelos de calibração em NIRS e DRIFTS para a quantificação das frações de argila e areia, em amostras de solos de classes diferentes - Latossolo Vermelho (predominante, Nitossolo, Argissolo Vermelho e Neossolo Quartzarênico - e avaliar qual dessas duas técnicas é mais adequada para essa finalidade, assim como a interferência do agrupamento de amostras e da seleção de variáveis espectrais na qualidade desses modelos. Para isso, valores de referência obtidos pelo método do densímetro, método largamente utilizado nos laboratórios de análise de solo, foram correlacionados com valores de absorbância em NIRS e DRIFTS pela ferramenta estatística PLS (Partial Least Squares, obtendo-se altos coeficientes de determinação (R², de 0,95, 0,90 e 0,91 para argila, silte e areia, respectivamente, na validação externa. Isso confirma a aplicabilidade das técnicas espectroscópicas na análise granulométrica do solo para fins agrícolas. O agrupamento das amostras segundo a localização e a seleção de variáveis espectrais pouco influenciou na qualidade dos modelos. A técnica espectroscópica mais indicada para essa finalidade foi a DRIFTS.

Se determinaron los tiempos de reacción completa de las partículas, con tamaño fijo y decreciente, considerando el modelo centro sin reaccionar, y como posibles pasos controlantes: difusión externa en la película líquida, difusión a través de la capa de productos formados (costra, la reacción química en partículas de tamaño fijo y difusión externa en la película líquida en partículas de tamaño decreciente. El análisis de los resultados permitió descartar como pasos controlantes la reacción química y la difusión en la costra. Se concluye que la difusión externa es el paso que con mayor probabilidad controla el proceso de neutralización.

    Full Text Available Os lodos de esgoto são materiais orgânicos ricos em nutrientes com potencial para o uso agrícola. A utilização desses materiais, no entanto, pode ser limitada pela presença de metais pesados na sua composição. Esta pesquisa teve por objetivos: (a avaliar a solubilidade de Cd, Pb e Zn em dois tipos de solos tratados com lodo de esgoto enriquecido com esses metais; (b verificar o efeito do tempo de contato nas mudanças da distribuição de Cd, Pb e Zn nas diferentes formas químicas de dois solos tratados com lodo de esgoto enriquecido com esses metais; (c verificar a influência das frações inorgânicas e orgânicas do lodo na dinâmica destes metais no solo. O enriquecimento do lodo de esgoto consistiu em adicionar Cd, Pb e Zn a um lodo de esgoto urbano produzido na Estação de Tratamento da Ilha do Governador (ETIG, Rio de Janeiro (RJ. Após 20 dias de incubação, sob umidade constante (50 % g g-1, o lodo enriquecido foi utilizado para a instalação de experimentos em amostras de duas classes de solos: Latossolo Vermelho-Amarelo (LV e Argissolo Vermelho-Amarelo (PV. Em laboratório, as amostras dos solos foram incubadas com quantidades equivalentes a 0; 20; 40 e 80 t ha-1 de lodo de esgoto enriquecido. Nos tempos de contato solo-lodo enriquecido de 4, 12, 16, 24 e 160 semanas, amostras de solos foram retiradas e submetidas à extração seqüencial de Cd, Pb e Zn. Observou-se, através da extração seqüencial, que compostos orgânicos solúveis formaram complexos, principalmente com cádmio e zinco, mantendo teores elevados destes elementos associados à fração solúvel em água durante todo o período experimental. A incorporação de compostos inorgânicos de Fe e Mn, através do lodo de esgoto, permitiu que o Cd, Pb e Zn se ligassem em sua maior parte, à fração extraível com hidroxilamina. Com o tempo de incubação, observou-se decréscimo dessa fração com aumento da fração residual, indicando decréscimo na

    This report presents the details of new geophysical work for the Paso Robles geothermal area, California performed under terms of the second year contract, 1979-80 between the US Department of Energy (DOE) and the California Division of Mines and Geology (CDMG). The report contains two sections. The first section is to provide background for the reader and consists of a reprint from CDMG's first year report (1979-80) to DOE. It describes only the Paso Robles studies performed by CDMG in its first year effort. The second section provides new information developed by CDMG in its 1979-80 studies concerning the geophysical survey of the Paso Robles geothermal area. Included in the first section is some general background information concerning the geology and geothermal occurrences in the Southern Coast Ranges, as well as the more detailed information dealing with the Paso Robles area proper. The second section is concerned only with discussion and interpretation of results for two geophysical methods that have so far been used by CDMG in the area: the ground magnetic and gravity surveys. The CDMG studies of the Paso Robles area are not yet complete and additional studies using newly acquired resistivity equipment are planned for the near future, as are more complete surveys of existing wells and new studies of the geothermal aquifers present in the area. A final report to DOE on the Paso Robles area is planned following completion of those studies.

  5. "I am Your Mother and Your Father!" In Vitro Derived Gametes and the Ethics of Solo Reproduction.

    Cutas, Daniela; Smajdor, Anna

    2017-12-01

    In this paper, we will discuss the prospect of human reproduction achieved with gametes originating from only one person. According to statements by a minority of scientists working on the generation of gametes in vitro, it may become possible to create eggs from men's non-reproductive cells and sperm from women's. This would enable, at least in principle, the creation of an embryo from cells obtained from only one individual: 'solo reproduction'. We will consider what might motivate people to reproduce in this way, and the implications that solo reproduction might have for ethics and policy. We suggest that such an innovation is unlikely to revolutionise reproduction and parenting. Indeed, in some respects it is less revolutionary than in vitro fertilisation as a whole. Furthermore, we show that solo reproduction with in vitro created gametes is not necessarily any more ethically problematic than gamete donation-and probably less so. Where appropriate, we draw parallels with the debate surrounding reproductive cloning. We note that solo reproduction may serve to perpetuate reductive geneticised accounts of reproduction, and that this may indeed be ethically questionable. However, in this it is not unique among other technologies of assisted reproduction, many of which focus on genetic transmission. It is for this reason that a ban on solo reproduction might be inconsistent with continuing to permit other kinds of reproduction that also bear the potential to strengthen attachment to a geneticised account of reproduction. Our claim is that there are at least as good reasons to pursue research towards enabling solo reproduction, and eventually to introduce solo reproduction as an option for fertility treatment, as there are to do so for other infertility related purposes.

O trabalho foi realizado em casa de vegetação da UFCG/CSTR em Patos, PB. Amostras de um solo salino-sódico foram obtidas do Perímetro Irrigado de São Gonçalo. O experimento constitui-se de um tipo de solo, duas espécies, três doses de gesso agrícola (00, 100 e 200% da NG e 4 repetições. As parcelas foram distribuídas em DIC. As sementes de pinha e goiaba foram semeadas em tubetes e após 30, as mudas foram transplantadas segundo padronização do diâmetro do coleto, número de folhas, altura e transferidas para os solos salinizados, observando o crescimento através de medições semanais da altura das plantas por um período de 104 dias. Houve redução significativa nos teores de sódio no solo com o aumento do nível de gesso aplicado, o mesmo ocorrendo para o pH e melhoria nas propriedades químicas do solo. As mudas apresentaram redução na altura, número de folhas, na massa seca da parte aérea e da raiz com a aplicação do corretivo. A aplicação de gesso em solos salino-sódico para cultivo de goiaba e pinha não apresentou resultados satisfatórios.

    Full Text Available Solos com umidade ótima de compactação menor que a capacidade de campo e solos com má drenagem são mais propensos a serem compactados nas operações de exploração florestal. O conhecimento dessas variáveis permite classificar os solos quanto à sua suscetibilidade à compactação, no entanto essas determinações demandam tempo, recursos e equipamentos específicos. Utilizando 13 solos florestais com ampla variação textural, das fazendas Ariona e Santa Rosa pertencentes à Cia. Suzano de Papel e Celulose, situadas no Estado de São Paulo, desenvolveu-se um índice, denominado diâmetro médio ponderado de partículas, que permitiu estimar a umidade ótima de compactação, a capacidade de campo e o limite líquido baseado apenas na distribuição de tamanho de partículas. Com base nessas características físicas e no consumo médio diário de água de um plantio de eucalipto, foram estabelecidas unidades de colheita a partir do número de dias de repouso necessários para o teor de água de um solo ficar abaixo da umidade ótima de compactação. Tais unidades agrupam solos que precisam do mesmo número de dias após uma chuva (0 a 10 dias para poderem ser explorados, visando diminuir o impacto da colheita florestal e, em consequência, evitar a necessidade de preparo do solo para diminuir a compactação provocada por essas operações.

Este trabalho teve como objetivo avaliar, em diferentes locais de amostragem, as propriedades físicas de solos cultivados com lavouras cafeeiras, sob distintos manejos, no sul do Estado do Espírito Santo. Foram realizadas amostragens nas camadas de 0,00-0,20 m e 0,20-0,40 m, na parte superior da projeção da "saia" do cafeeiro, em relação ao sentido de declive do terreno. Foram utilizadas, para o estudo, lavouras representativas da região sul do Estado, apresentando a mesma classe de solo (Latossolo Vermelho-Amarelo distrófico, relevo forte ondulado, tendo os seguintes manejos: M1 - irrigação por gotejamento, calagem a cada dois anos, adubação, roçadas e uso da palha de café; M2 - adubação, roçadas e capinas; M3 - capinas e roçadas. Em cada manejo, foram avaliados os seguintes locais de amostragem: TS - terço superior, TM - terço médio; TI - terço inferior, ao longo do declive. As propriedades físicas avaliadas foram: densidade do solo, porosidade total, macroporosidade, microporosidade e resistência do solo à penetração. Para as condições experimentais, a resistência do solo à penetração, a macroporosidade e a microporosidade mostraram-se importantes indicadores físicos da qualidade do solo, influenciados pelo manejo, local de amostragem e camada avaliada.

    Full Text Available A compreensão e a quantificação do impacto do uso e manejo do solo na qualidade física são fundamentais no desenvolvimento de sistemas agrícolas sustentáveis. Com o objetivo de avaliar o efeito de sistemas de manejo de solo e de rotação de culturas sobre alguns atributos físicos de solo em um experimento instalado em 1985, em Latossolo Vermelho Distrófico típico argiloso, em Passo Fundo (RS, estudou-se a variação desses atributos entre 2001 e 2005. Os tratamentos consistiram de quatro modos de manejo de solo: 1 plantio direto (PD; 2 cultivo mínimo (CM; 3 preparo convencional de solo com arado e grade de discos (PCD e 4 preparo convencional de solo com arado de aivecas e grade de discos (PCA, e três sistemas de rotação de culturas: I (trigo/soja, II (trigo/soja e ervilhaca/milho ou sorgo e III (trigo/soja, aveia branca/soja e ervilhaca/milho ou sorgo. O delineamento experimental foi em blocos completos ao acaso, com parcelas subdivididas e três repetições. A parcela foi constituída pelos sistemas de manejo de solo, e as subparcelas, pelos sistemas de rotação de culturas. Amostras de solo também foram coletadas em um fragmento de floresta subtropical adjacente ao experimento, como testemunha da condição original do solo. Os sistemas de manejo e de rotação de culturas influenciaram os atributos físicos do solo quando comparados entre si e com a condição sob floresta subtropical. Em quatro anos (2001 a 2005 ocorreram alterações significativas nos atributos físicos dos solos entre os distintos tipos de manejo. No sistema PD houve maior densidade de solo e microporosidade em comparação aos demais, principalmente na camada subsuperficial, e os sistemas de rotação de plantas não afetaram positivamente os atributos físicos de solo independentemente do tipo de manejo.Evaluation and quantification of soil use impact on its physical quality are important to achieve sustainable cropping systems.

    Full Text Available Resumen: Este ensayo analiza las percepciones y apreciaciones a través de las cuales los profesores construyen una imagen de lo que significa ser maestro y el interés que los llevó a serlo. Los acercamientos cualitativos para la construcción de los datos se hicieron por medio de entrevistas y, para su análisis se utilizaron técnicas de análisis etnográfico entretejidas con el análisis del discurso. A partir del análisis de los discursos, es posible afirmar que los maestros no se adhirieron a la profesión docente de manera anticipada impulsados por una fuerza interna independiente de las condiciones objetivas de su existencia, sino que, el despertar del gusto por enseñar se gestó en las instituciones de formación docente y en el ejercicio mismo de la docencia. Dicho de otro modo, el interés por la profesión docente es histórico y se construye día a día. Insertos en la profesión, los maestros sienten que están hechos para ella, la valoran y construyen una imagen de lo que significa ser profesor de educación secundaria. Esta articula las percepciones y apreciaciones que construyen sobre su trabajo en relación con los estudiantes en el espacio pedagógico y la valoración que los otros hacen sobre su desempeño.

    Full Text Available Metais pesados formam um grupo de elementos com particularidades relevantes e de ocorrência natural no ambiente, como elementos acessórios na constituição de rochas. Esses elementos, apesar de associados à toxidez, exigem tratamento diferenciado em relação aos xenobióticos, uma vez que diversos metais possuem essencialidade (Fe, Mn, Cu, Zn e Ni e benefício (Co comprovados para as plantas. Nesse contexto, o objetivo deste trabalho foi determinar os teores naturais dos metais Fe, Mn, Zn, Ni, Cu e Co nos solos de referência de Pernambuco. Foram coletadas amostras de solo nas três regiões fisiográficas (Zona da Mata, Agreste e Sertão, dos dois primeiros horizontes dos 35 solos de referência do Estado de Pernambuco. A digestão das amostras baseou-se no método 3051A (USEPA, 1998, e a determinação foi efetuada em ICP-OES. Correlações significativas foram estabelecidas entre os metais e entre estes e a fração argila do solo, em ambos os horizontes, indicando a associação comum da maioria dos metais com solos mais argilosos. A maioria dos solos apresentou teores de Fe, Mn, Zn, Cu, Ni e Co menores que os de solos de outras regiões do País, com litologia mais máfica, o que corrobora o fato de que os teores desses elementos são mais diretamente relacionados aos minerais Fe-magnesianos. Os resultados indicam baixo potencial dos solos de Pernambuco em liberar Cu, Co e Ni para plantas, enquanto deficiências de Zn, Fe e Mn são menos prováveis. Os teores naturais de Fe, Mn, Zn, Cu, Ni e Co determinados podem ser utilizados como base para definição dos Valores de Referência de Qualidade para os solos de Pernambuco, de acordo com o preconizado pela legislação nacional.

    Full Text Available Atualmente os parâmetros da resistência ao cisalhamento dos solos podem ser uma ferramenta muito útil na estabilização de taludes e recuperação de voçorocas, bem como na adoção de práticas mecânicas de conservação para os solos agrícolas. Com o objetivo de avaliar a resistência ao cisalhamento de cinco solos da região de Lavras (MG e sua relação com o grau de intemperismo, realizou-se um experimento, utilizando uma prensa de cisalhamento direto, a qual permite ensaiar amostras indeformadas de solos. Essas amostras foram coletadas na profundidade de 0-0,03 m e submetidas ao ensaio de cisalhamento, para a definição das envoltórias de resistência e obtenção da coesão aparente (C e o ângulo de atrito interno (φ. Observou-se que C, de forma geral, foi maior para solos que apresentaram maior densidade, umidade a -0,01 MPa e maior teor de areia. Os valores de (φ foram maiores nos solos com maiores teores de argila. O Latossolo Vermelho-Amarelo distrófico (LVAd e o Argissolo Vermelho-Amarelo distrófico típico (PVAd, com densidades do solo, teores de areia e umidade a -0,01MPa maiores, apresentaram maiores resistências ao cisalhamento em relação ao Latossolo Vermelho distrófico (LVd, Cambissolo Háplico Tb distrófico (CXbd e Latossolo Vermelho distroférrico (LVdf, que apresentaram maiores teores de argila e matéria orgânica. Para a classe dos Latossolos, a resistência ao cisalhamento foi maior onde os índices Ki e Kr foram mais elevados, graças à estrutura em blocos apresentada pelo LVAd, que condicionou maior resistência ao cisalhamento. Do ponto de vista da resistência ao cisalhamento, os solos LVAd e PVAd mostraram-se mais resistentes a voçorocamento e ao preparo do solo.

    Full Text Available Foram estudados os efeitos da aplicação de composto de lixo urbano, proveniente da usina de compostagem São Matheus da cidade de São Paulo, na dose de 30 g dm-3 (60 t ha-1, na presença e ausência de calcário dolomítico e adubos minerais, sobre os teores de carbono orgânico, de nitrogênio total e de fósforo e enxofre disponíveis de 21 solos ácidos e cinco solos alcalinos, onde o calcário foi substituído por gesso. O experimento foi realizado em condições de casa de vegetação com os solos nas parcelas em blocos ao acaso, com três repetições e os tratamentos em subparcelas. O acúmulo de matéria orgânica, em virtude da aplicação do composto, foi evidente em solos com teores iniciais de carbono orgânico > 12 g dm-3 e de nitrogênio > 1,3 g dm-3, porém com relação C/N < 12. Nos demais solos, o acúmulo foi decorrente da interação entre a estabilidade da matéria orgânica do composto, da matéria orgânica nativa e as propriedades físicas e químicas dos solos. A aplicação do composto aumentou os teores de nitrogênio total e de enxofre disponível em todos os solos, porém o fósforo disponível somente foi aumentado nos solos ácidos. A aplicação do composto de lixo urbano como fertilizante orgânico é viável, porém seus efeitos sobre as propriedades químicas do solo devem ser monitorados.

    1998-06-01

    Full Text Available O experimento foi realizado em condições de casa de vegetação, na Universidade Federal de Uberlândia, no período de março a agosto de 1995, visando determinar, em sete classes de solo, a supressividade ao fungo Rhizoctonia solani e estudar o possível relacionamento dessa característica com a mineralogia, propriedades físicas e químicas e populações de fungos do solo. Após proceder à inoculação dos solos com R. solani, multiplicada em grãos de sorgo autoclavados, observou-se que o índice de doença em plântulas de soja aumentou em todos eles. Tal índice foi sempre maior na camada de 0-20 cm, associando-se com o maior teor de matéria orgânica, com exceção do Solo Orgânico eutrófico (SOe, o qual apresentou um índice de doença similar nas duas profundidades (0-20 e 20-40 cm. O efeito supressivo a R. solani, observado no material do Plintossolo distrófico (PTd e no Latossolo Vermelho-Escuro álico (LEa, relacionou-se com a textura muito argilosa, com a alta saturação por alumínio e com a vegetação (fase cerrado, mesmo com a ausência de Trichoderma spp. Os materiais do Solo Orgânico eutrófico (SOe, do Latossolo Roxo distrófico (LRd e da Terra Roxa Estruturada eutrófica (TRe apresentaram maior conducividade a R. solani , possivelmente relacionada com o caráter eutrófico e com o teor da matéria orgânica, decorrente do tipo de cobertura vegetal (fase vegetação. O material do Latossolo Vermelho-Escuro álico textura média (LEam e o do Latossolo Vermelho-Amarelo álico (LVa mostraram comportamento intermediário. O índice de doença correlacionou-se negativamente com a saturação por alumínio e teor de argila e positivamente com a saturação de bases (V e com o pH. A mineralogia parece não ter influência direta na supressividade ou conducividade dos solos estudados, provavelmente por variar apenas no que se refere às formas de óxidos de ferro.

    Greater longevity in the UK population has led to the increasing diversity of women experiencing aging in a multitude of ways. Internationally, gender inequalities in aging are still relatively invisible within both government policy and everyday life for particular groups of women. This article explores the concept of women growing older "solo"-by which we mean women who find themselves nonpartnered and aging without children as they move into later life. We report on the findings from a mixed-methods survey of 76 solo women in the UK aged 50 years and over, used to provide a broader overview of the issues and challenges they face as they move into later life. Qualitative data from the survey captured respondents' perspectives about the links between their relationships status and well-being in later life and highlighted specific cumulative disadvantages emerging for some women as a result of their solo lifestyles. We discuss two key themes that were identified, "solo-loneliness" and "meaningful futures," in conjunction with the relevant literature and make suggestions for future research within gender and aging studies that could enhance more positive approaches to solo lifestyles.

Neste estudo, avaliaram-se a ocorrência e a diversidade dos FMAs em quatro locais com gramíneas em uma área de solo contaminado com metais pesados pela extração e industrialização do Zn. Verificou-se a ocorrência generalizada dos FMAs nos locais estudados, sendo esta influenciada pelas concentrações de metais no solo. Encontrou-se um total de 21 espécies, sendo: sete pertencentes ao gênero Acaulospora, seis de Scutellospora, cinco de Glomus, duas de Gigaspora e uma de Entrophospora,Glomus occultum, Acaulospora morrowiae, Acaulospora mellea, Glomus intraradices, Glomus clarum e Scutellospora pellucida foram as de maior ocorrência. A densidade de esporos, a riqueza de espécies e o aumento da dominância relacionaram-se inversamente com as concentrações de metais no solo. Acaulospora mellea, Glomus clarum e Glomus occultum dominaram as populações de esporos no solo. Concluiu-se que os metais pesados exerceram efeito diferenciado sobre os FMAs, dependendo do grau de poluição.

    Disclosure of donor conception to children was compared between solo mother and two-parent families with children aged 4-8 years conceived since the removal of donor anonymity in the UK. Semi-structured interviews were conducted with 31 heterosexual solo mothers and 47 heterosexual mothers with partners to investigate their decisions and experiences about identifiable donation and disclosure to their children. No significant difference was found in the proportion of mothers in each family type who had told their children about their donor conception (solo mothers 54.8%; partnered mothers 36.2%). Of those who had not told, a significantly higher proportion of solo mothers than partnered mothers intended to disclose (P parents will tell their children about their origins or their entitlement to request the identity of their donor at the age of 18 years. Further qualitative research would increase understanding of solo mothers' attitudes towards disclosure. Copyright © 2016 The Authors. Published by Elsevier Ltd.. All rights reserved.

As árvores foram selecionadas em parcela permanente (Caracaraí, RR e divididas em quatro classes de produção: alta, média, baixa e muito baixa. Em novembro de 2009, amostras de solo e folhas foram coletadas para se avaliar a fertilidade do solo, o número de esporos de fungos micorrízicos arbusculares e o estado nutricional das árvores. Árvores com maior produção de frutos ocorreram associadas a maior teor de Al trocável na camada de 0-20 cm do solo, bem como a menor valor de pH e saturação por bases. A variável discriminante resultante deste estudo não foi considerada como responsável por interferir no potencial produtivo da castanheira-do-brasil, mas serviu como indicativo de que árvores mais produtivas contribuem na remoção de bases trocáveis, favorecendo a acidificação do solo.

    2012-01-01

    The question of why animals participate in duets is an intriguing one, as many such displays appear to be more costly to produce than individual signals. Mated pairs of yellow-naped amazons, Amazona auropalliata, give duets on their nesting territories. We investigated the function of those duets with a playback experiment. We tested two hypotheses for the function of those duets: the joint territory defense hypothesis and the mate-guarding hypothesis, by presenting territorial pairs with three types of playback treatments: duets, male solos, and female solos. The joint territory defense hypothesis suggests that individuals engage in duets because they appear more threatening than solos and are thus more effective for the establishment, maintenance and/or defense of territories. It predicts that pairs will be coordinated in their response (pair members approach speakers and vocalize together) and will either respond more strongly (more calls and/or more movement) to duet treatments than to solo treatments, or respond equally to all treatments. Alternatively, the mate-guarding hypothesis suggests that individuals participate in duets because they allow them to acoustically guard their mate, and predicts uncoordinated responses by pairs, with weak responses to duet treatments and stronger responses by individuals to solos produced by the same sex. Yellow-naped amazon pairs responded to all treatments in an equivalently aggressive and coordinated manner by rapidly approaching speakers and vocalizing more. These responses generally support the joint territory defense hypothesis and further suggest that all intruders are viewed as a threat by resident pairs.

    Paired indoor and outdoor concentrations of fine and coarse particulate matter (PM), PM2.5 reflectance [black carbon(BC)], and nitrogen dioxide (NO 2 ) were determined for sixteen weeks in 2008 at four elementary schools (two in high and two in low traffic density zones) in a U.S.-Mexico border community to aid a binational health effects study. Strong spatial heterogeneity was observed for all outdoor pollutant concentrations. Concentrations of all pollutants, except coarse PM, were higher in high traffic zones than in the respective low traffic zones. Black carbon and NO 2 appear to be better traffic indicators than fine PM. Indoor air pollution was found to be well associated with outdoor air pollution, although differences existed due to uncontrollable factors involving student activities and building/ventilation configurations. Results of this study indicate substantial spatial variability of pollutants in the region, suggesting that children's exposures to these pollutants vary based on the location of their school. - Highlights: → First binational investigation characterizing traffic air pollutants at four schools in El Paso, USA and Cd. Juarez, Mexico. → Paired in-outdoor sampling of PM 2.5 , PM 10-2.5 , reflectance [black carbon(BC)], and NO 2 for 16 weeks in 2008 at each school. → Two schools (one in each city) were located in high traffic density areas and the other two in areas of low traffic density. → Usage of spatially resolved environmental indictors of traffic pollutants in a range of exposure settings. → Substantial intra-urban spatial variability in pollutant concentrations observed between and within the two cities. - Spatial variability in traffic-mediated pollutant concentrations can exist at the intra-urban level and ambient monitoring sites may not accurately represent these concentration gradients.

    Hispanics in El Paso, TX, a large American-Mexican border city constitute 85% of the population. Limited cancer research has been conducted in this population. We sought to study the prevalence of BRCA mutations among Hispanic patients of Mexican origin, identify reported Mexican founder or recurrent mutations, and study the breast cancer characteristics in mutation carriers. Hispanic women of Mexican descent with a personal history of breast cancer, who presented consecutively for genetic cancer risk assessment, were enrolled in an Institutional Review Board-approved registry and underwent BRCA testing based on national guidelines. The characteristics of tumors and patients with positive BRCA mutation were analyzed. 88 patients were screened; 18 patients (20%) were BRCA carriers. Among BRCA carriers, 72% were diagnosed with breast cancer at younger than 50 years, 61% had "Triple negative disease". BRCA carriers had a significantly higher Body Mass Index (BMI) than non-carriers. Thirteen patients had BRCA1 mutations and five had BRCA2 mutations. A total of 17 deleterious BRCA Mutations were observed. Seven have been previously reported as specific genes from Mexico as country of origin. Five new mutations in BRCA carriers of Mexican descent were identified. Hispanic breast cancer patients of Mexican origin present at a younger age, and have predominantly triple negative tumors and high BMI. We identified 5 new mutations not reported previously in Hispanic BRCA carriers of Mexican descent. Interestingly, 41% of BRCA mutations identified have been reported as recurrent mutations in Hispanic individuals from Mexico as the country of origin. A more cost-effective approach to initial screening of Hispanic individuals based on country of origin is desirable and would potentially decrease the number of cases requiring complete sequencing.

    Geologic and hydrologic data for the Municipal Solid Waste Landfill Facility on the U.S. Army Air Defense Artillery Center and Fort Bliss in El Paso County, Texas, were collected by the U.S. Geological Survey in cooperation with the U.S. Department of the Army. The 106.03-acre landfill has been in operation since January 1974. The landfill contains household refuse, Post solid wastes, bulky items, grass and tree trimmings from family housing, refuse from litter cans, construction debris, classified waste (dry), dead animals, asbestos, and empty oil cans. The depth of the filled areas is about 30 feet and the cover, consisting of locally derived material, is 2 to 3 feet thick. Geologic and hydrologic data were collected at or adjacent to the landfill during (1) drilling of 10 30- to 31-foot boreholes that were completed with gas-monitoring probes, (2) drilling of a 59-foot borehole, (3) drilling of a 355-foot borehole that was completed as a ground-water monitoring well, and (4) in situ measurements made on the landfill cover. After completion, the gas- monitoring probes were monitored on a quarterly basis (1 year total) for gases generated by the landfill. Water samples were collected from the ground-water monitoring well for chemical analysis. Data collection is divided into two elements: geologic data and hydrologic data. Geologic data include lithologic descriptions of cores and cuttings, geophysical logs, soil- gas and ambient-air analyses, and chemical analyses of soil. Hydrologic data include physical properties, total organic carbon, and pH of soil and sediment samples; soil-water chloride and soil-moisture analyses; physical properties of the landfill cover; measurements of depth to ground water; and ground-water chemical analyses. Interpretation of data is not included in this report.

Este desequilibrio natural de los sistemas obligan a las organizaciones a variar su modelo estático para poder responder, de manera eficiente, a los cambios que se presentan. Ante un estado de cambio constante, la innovación debe ser la herramienta que permita enlazar las actividades estratégicas con las acciones operativas que son llevadas al campo práctico a través de la herramienta de los proyectos. Ese triángulo: Proyectos, Innovación y Estrategia, proporciona el soporte sobre el cual da los pasos la organización. Para poder enlazar dichas aristas se debe recurrir al uso de modelos de gestión, tecnología, destrezas y habilidades de comunicación interpersonal y empresarial. Por tanto, el PIE puede considerarse como un estándar en donde la Estrategia es el punto de partida; seguido por la Innovación como característica importante de la Estrategia, ya que constituye el medio o proceso para canalizar y desarrollar los productos de la estrategia; luego, finalmente, los Proyectos como herramienta para lograr los objetivos estratégicos innovadores planteados. Indispensable debe ser, ante cualquier acción a seguir, que las iniciativasimplementadas, las cuales se suman a la estrategia como eslabones de una cadena, representen un real aporte de valor en los cambios previstos por la organización.

    Les escribimos esta carta para comunicarle un mensaje sumamente importante sobre las preparaciones de emergencia. Historicamente, hemos sufrido terremotos aqui en el Area de la Bahia de San Francisco que han causado graves privaciones para los residentes de la comunidad y da?os increibles a nuestras ciudades. Es probable que suframos un terremoto de gran magnitud en los proximos 30 a?os. Muchos de nosotros venimos de otros paises donde hemos pasado por terremotos y por eso creemos entenderlos. Sin embargo, la manera que nos preparamos para terremotos en nuestros paises de origen puede ser distinta a la que empleamos aca en los Estados Unidos. Muy pocas personas mueren a causa de los derrumbes de los edificios en el Area de la Bahia porque la mayoria de los edificios son construidos para resistir el sacudimiento de la tierra. Pero es muy probable que su familia no tenga atencion medica, alimentos o que esten separados del uno al otro por dias o semanas. Finalmente depende de usted mantener a su familia a salvo hasta que llegue asistencia, por eso les pedimos que nos unamos para aprender a cuidar a su familia antes, durante, y despues de un terremoto. El primer paso es leer este libro. Cada uno de su familia, ni?os y adultos, pueden aprender como prepararse para un terremoto. Haga participar e incluya sus ni?os; pueden ayudarle a prepararse. Aproveche las clases ofrecidas en su comunidad sobre las preparaciones de terremotos por la Cruz Roja Estadounidense (American Red Cross). Estos cursos de preparacion son gratis y disponibles en espa?ol para todos en la comunidad sin tomar en cuenta la historia de la familia, estado legal, genero o edad. Les recomendamos que tome ventaja de estas clases gratuitas. Para mas informacion consulte la ultima pagina de este libro. Recuerde que un terremoto puede ocurrir sin aviso y la unica manera de reducir el da?o de terremotos es estar preparados. !Preparese!

  17. Physicians’ Perceptions of Autonomy across Practice Types: Is Autonomy in Solo Practice a Myth?

    Lin, Katherine Y.

    2013-01-01

    Physicians in the United States are now less likely to practice in smaller, more traditional, solo practices, and more likely to practice in larger group practices. Though older theory predicts conflict between bureaucracy and professional autonomy, studies have shown that professions in general, and physicians in particular, have adapted to organizational constraints. However, much work remains in clarifying the nature of this relationship and how exactly physicians have adapted to various organizational settings. To this end, the present study examines physicians’ autonomy experiences in different decision types between organization sizes. Specifically, I ask: In what kinds of decisions do doctors perceive autonomous control? How does this vary by organizational size? Using stacked “spell” data constructed from the Community Tracking Study (CTS) Physician Survey (1996–2005) (n=16,519) I examine how physicians’ perceptions of autonomy vary between solo/two physician practices, small group practices with three to ten physicians, and large practices with ten or more physicians, in two kinds of decisions: logistic-based and knowledge-based decisions. Capitalizing on the longitudinal nature of the data I estimate how changes in practice size are associated with perceptions of autonomy, accounting for previous reports of autonomy. I also test whether managed care involvement, practice ownership, and salaried employment help explain part of this relationship. I find that while physicians practicing in larger group practices reported lower levels of autonomy in logistic-based decisions, physicians in solo/two physician practices reported lower levels of autonomy in knowledge-based decisions. Managed care involvement and ownership explain some, but not all, of the associations. These findings suggest that professional adaptation to various organizational settings can lead to varying levels of perceived autonomy across different kinds of decisions. PMID:24444835

    The Solo Smart pericardial aortic valve has been widely used in Europe as an option for aortic valve replacement (AVR). We are reporting early and midterm clinical outcomes of AVR with the Solo Smart valve in a single North America center. This is a retrospective study of 270 consecutive patients who had AVR at Mazankowski Alberta Heart Institute from February 2011 to March 2015. Follow-up and echocardiographic data were collected retrospectively from electronic and paper charts. Univariate and multivariate analysis were performed to evaluate the results. The mean age was 71.2±10.0 years, 67.4% were male, and 79.3% had combined procedures. Mean STS Score was 4.18±3.91. Early mortality was 3.7% for the entire group and 0% for isolated aortic valve replacement group. Mean cross-clamp time for isolated AVR and AVR with concomitant procedure was 70.8±12.7min and 117.0±45.0min, respectively. Permanent pacemaker implantation was necessary in 2.2% of patients. Echocardiography demonstrated a reduction in mean gradients from 40.8±17.4mmHg to 7.6±3.7 mmHg and peak gradient from 72.5 ± 48.8 mmHg to 15.5±7.5 mmHg. The 1-, 3-, and 5- year overall survival was 93.0%, 86.5% and 75.9%, respectively. At 5 years, freedom from valve-related death was 92.4%, freedom from structural valve deterioration and freedom from aortic valve reoperation were 96.4% and 98%, respectively. The Solo Smart valve is safe and has excellent hemodynamic performance. Aortic valve reoperation and rates of valve-related adverse events during midterm follow-up were low.

Using qualitative method and content analysis, the research found the following conclusions: First, the diversity of communities—ethnic, cultural, or religious— has received little attention from the preacher at various mosques and majelis taklim. Second, in addition to multicultural values, sermons and religious lectures contains some values of anti-multicultural, such as prejudice and stereotypes against other groups, particularly in relation to the non-Muslim and western countries. Third, the sermons material and religious lectures implied the intensity of purification. Along with the movement, religious preaching implied resistance to local culture (Java, which is considered as the main source of religious impurity. Finally, the development trend of Islam in Solo implies religious radicalization as reflected in hostility towards the local culture, foreigners and non-Muslims.Keywords: multiculturalism, antimulticulturalism, radicalism, mosque, religious speech AbstrakPenelitian ini bertujuan untuk mengidentifikasi lingkup materi khotbah agama dan khotbah di masjid-masjid dan majelis taklim di Solo, dan mengidentifikasi aspek-aspek multikultural dan anti-multikultural yang disampaikan dalam khotbah dan ceramah. Riset ini menggunakan metode penelitian kualitatif dan analisis isi.

    The study aim was to present the short- and mid-term results for patients who underwent aortic valve replacement (AVR) with the Sorin Freedom Solo third-generation stentless prosthetic valve. AVR with a Sorin Freedom Solo valve was performed in 14 patients between March 2006 and March 2011. Patients aged > or = 60 years (male:female ratio 6:8; mean age 73.28 +/- 5.42 years) who required AVR with the Sorin Freedom Solo valve according to the surgeon's choice were included in the study. The valvular prosthesis was implanted in the supra-annular position, using a single suture line. Eight patients underwent an isolated AVR; combined interventions were carried out in the other patients due to concomitant cardiac disease. One patient died during the immediate perioperative period, and two more during the follow up, from non-cardiac causes. The mean maximum transvalvular gradient of patients with aortic stenosis was 88.1 +/- 20.2 mmHg, and this fell to 26.4 +/- 7.6 mmHg during the early postoperative period. The mean gradient at one year of follow up was further decreased to 19.4 +/- 5.3 mmHg. The left ventricular end-diastolic and end-systolic diameters were also significantly reduced, from 4.8 +/- 0.9 to 4.3 +/- 0.6 cm and from 3.2 +/- 0.6 to 2.8 +/- 5.3 cm, respectively. The average left ventricular ejection fraction was 60.2 +/- 4.9% preoperatively, and 63.2 +/- 2.1% at one year after surgery (p = NS). No paravalvular leakage, endocarditis, prosthesis failure or neurologic events were reported among patients. The Sorin Freedom Solo stentless valve has provided good early and intermediate-term results. Implantation of the prosthesis is straightforward, with low rates of morbidity and mortality. However, these data require further support from larger patient series and long-term follow up.

    Full Text Available A química do solo vem estudando o comportamento da fração mineral dos solos tropicais intemperizados, incluindo a eletroquímica, o desenvolvimento de cargas e o fenômeno de adsorção. Por causa do amplo espectro a ser coberto no entendimento do comportamento da fração mineral, somado às dificuldades metodológicas, o estudo da complexa fração orgânica dos solos foi relativamente menos desenvolvido. A atual proposta revisita os primeiros trabalhos referentes à química de solos tropicais, buscando relacioná-los com dados de eletroquímica dos estoques de carbono do solo. O objetivo deste trabalho foi revisar aspectos de eletroquímica de solos, determinar e relacionar os pontos de carga zero, por diferentes métodos, os potenciais da dupla camada elétricae a eletroquímica do húmus de solos modais brasileiros, em uma sequência típica de intemperismo, visando a gerar informações para o seu manejo e conservação. Os métodos de estimativa dos ponto de carga zero dos solos apresentam resultados variados, mas com a mesma tendência entre os solos. Há predomínio de cargas negativas em ambas as camadas dos solos estudados. As cargas negativas dos coloides estão diretamente associadas à disponibilidade de elétrons do húmus e ambas diminuem com o estádio de intemperismo do solo.

The centre of the spheres of influence was localized using a water-air interface constituted by a metal cylinder filled with 200 liters of water. For Solo 40, the discrepancy between the two measurement centres was 6 cm. This shift value, which is quite acceptable, does not require any correction for these measurements, even when the soil is heterogeneous. For CNP 501 B, the discrepancy between the neutron and gamma measurement was 11 cm, i.e. nearly twice the value observed with Solo 40. In soils with a marked vertical heterogeneity, it therefore seems preferable to operate a 11 cm shift of the probe between the moisture and density measurements [fr

    Research has demonstrated that co-offending dyads and groups often use more violence than individual offenders. Despite the attention given to co-offending by the research community, kidnapping remains understudied. Stranger kidnappings are more likely than non-stranger kidnappings to involve the use of a weapon. Public fear of stranger kidnapping warrants further examination of this specific crime, including differences between those committed by solo and multi-offender groups. The current study uses National Incident-Based Reporting System (NIBRS) data to assess differences in use of violence among 4,912 stranger kidnappings by solo offenders and multi-offender groups using cross-tabulations, ordinal regression, and logistic regression. The results indicate that violent factors are significantly more common in multi-offender incidents, and that multi-offender groups have fewer arrests than solo offenders. The implications of these findings are discussed. © The Author(s) 2016.

    Full Text Available Com o objetivo de avaliar a disponibilidade de fósforo em amostras de solos representativos da Amazônia, desenvolveu-se um experimento em casa de vegetação do Centro de Energia Nuclear na Agricultura, Piracicaba (SP, de outubro de 1993 a março de 1994, utilizando-se amostras da camada superficial de cinco solos (LA-médio, LA-argiloso, LA-muito argiloso, PV-argiloso e PV-muito argiloso. Foram usados, como fontes de P, superfosfato triplo, termofosfato yoorin em pó, termofosfato yoorin semi-acabado e fosfato natural da Carolina do Norte, nas doses de P equivalentes a 0, 40, 80 e 120 mg kg-1 de solo. Caupi e arroz foram usados como plantas-testes, e os resultados de produção de matéria seca e de P acumulado na parte aérea foram correlacionados com os de teores de P nas amostras de cada solo. A extração de P foi efetuada por meio dos métodos da resina trocadora de ânions, Mehlich-1, Mehlich-3 e Bray-I. Os resultados obtidos demonstraram que o extrator Mehlich-1 extraiu grandes quantidades de fósforo nos tratamentos com fosfato natural da Carolina do Norte. Independentemente da fonte de fósforo utilizada, o extrator Mehlich-3 apresentou as melhores correlações com o caupi e o arroz. Os extratores Mehlich-3 e Bray-I apresentaram maior sensibilidade às variações de solo. O extrator Mehlich-3 mostrou-se adequado na avaliação da disponibilidade de fósforo para as plantas, em diferentes condições de solos e fontes de fósforo.

    Full Text Available O objetivo deste trabalho foi avaliar a adsorção de B em quatro solos de várzea da região de Lavras, MG, por meio dos parâmetros das isotermas de Langmuir e Freundlich, no período de outubro a novembro de 1998. Amostraram-se solos Aluvial, Glei Pouco Húmico, Glei Húmico, e Orgânico artificialmente drenado, coletados na camada de 0-20 cm e peneirados para 2 mm. Amostras com e sem calagem foram incubadas durante 30 dias. Duplicatas de 4,0 g de solo de cada classe foram acondicionadas em tubos de polietileno com oito diferentes doses de B (0, 2, 4, 8, 12, 16, 24 e 32 mig mL-1 preparadas em CaCl2.2H2O 0,01 mol L-1, com ácido bórico como fonte. Os teores de B na solução de equilíbrio foram determinados pelo método da Azometina-H. Os resultados mostraram que alto teor de matéria orgânica confere ao solo Glei Húmico maior capacidade de adsorver boro. A matéria orgânica, a superfície específica, caulinita e alumínio trocável foram os atributos dos solos que se correlacionaram diretamente com a capacidade máxima de adsorção de B (CMAB. A calagem proporcionou diminuição da CMAB em todos os solos.

O experimento foi realizado em área de cana-de-açúcar com 380 ha, que compreendia quatro tipos de Latossolos, com diferentes texturas e fertilidades naturais. Foram coletadas 241 amostras de solo, na profundidade de 0,00-0,25 m. O índice de avermelhamento do solo foi calculado a partir dos valores de matiz, valor e croma das amostras, obtidos com espectroscopia de reflectância difusa. Foram ajustados modelos de regressão entre o fósforo adsorvido e a suscetibilidade magnética ou o índice de avermelhamento dos solos. A dependência espacial dos dados foi avaliada por meio de geoestatística. A suscetibilidade magnética correlaciona-se significativamente ao fósforo adsorvido, o que possibilita seu uso como componente de funções de pedotransferência para quantificação indireta do fósforo adsorvido ao solo. O índice de avermelhamento e a suscetibilidade magnética apresentam dependência espacial com o fósforo adsorvido. A suscetibilidade magnética e o índice de avermelhamento dos solos, avaliado pela espectroscopia de reflectância difusa, podem auxiliar no mapeamento e na identificação de áreas com diferentes potenciais de adsorção de fósforo.

    2018-04-01

    Full Text Available This paper is an examination of Djanet Sears’s Afrika Solo (1990 as a unique example of how Blacks in the global diaspora trace their genealogical roots back to Africa. Drawing from research in anthropology, cultural studies, and performance, the paper purports that Sears’s African-Canadian identity is underlined by her recuperation of a heritage, epistemes and performative aesthetics, and, real or imagined, practices that are not just Afrocentric but specifically Yoruba. Essentially, the paper examines Afrika Solo in the context of Black Aesthetic and more significantly as “text” in a Yoruba sense, which constitutes her own way of “going back to get it.” The paper is divided into two parts: the first part presents a general argument about Sears’s journey back to Africa and the culturally-rooted nature of the performance as opposed to feminist/gender readings of same, while the second part explores ways of understanding the play through the lens of Yoruba ritual and its aesthetics.

    Aim. Sonography has been brought in percutaneous nephrolithotripsy (PCNL) as an adjunct to or substitute for X-ray to restrict radiation exposure. This study was designed to investigate the possible predictors for the success of the solo sonographically guided PCNL. Methods. 148 consecutive cases were prospectively enrolled. All steps of PCNL were performed solely with sonography guidance under spinal anesthesia. Residual stones were evaluated the day after surgery using sonography and plain radiography. Results. The mean age was 46 ± 15 years; 40% of kidneys had hydronephrosis. The mean stone burden was 504 ± 350 mm(2). The mean duration of surgery was 43 ± 21 minutes. The early stone-free rate was 92% in inferior or middle calyceal stones, 89.5% in single pelvic stones, 81.5% in partial staghorn stones, and 61.9% in staghorn stones. The mean residual stone size was 13 ± 8 mm. Logistic regression showed that a lower age and a larger stone burden significantly predicted positive residual stones. Fifteen percent of patients presented with grade I or II and six percent showed grade III complication based on Clavien classification. There was no cases of organ injury or death. Conclusion. Solo ultrasonographically guided PCNL under spinal anesthesia is feasible with an acceptable stone-free rate and complication rate.

    2017-12-01

    Full Text Available This article presents an analysis of the Sonata in C for solo accordion written by the German composer Ernst-Lothar von Knorr and it is dedicated to the accordion producer Ernst Hohner. This musical composition was written in 1949. It represents the first creation in sonata form in the chamber repertoire for accordion from Germany. Ernst-Lothar von Knorr was influenced by the German academic school of the twentieth century and especially by one of the most prominent representatives of neoclassicism Paul Hindemith, who would later become his friend. He operates intensively with the compositional processes of neoclassicism, reflected strongly enough in the sonata for accordion. The revitalization of the forms, characteristic of compositions of the classical and pre-classical epochs (large tripartite form with episode in part I, polyphonic variations on basso ostinato in part II and the concert form in the finale, enriched by the free use of the chromatic scale and other innovations in this domain, determine clearly the approach of the Sonata in C for solo accordion to the neoclassical principles.

    2002-09-01

    Full Text Available Estudos desenvolvidos com arroz irrigado por inundação no estado do Rio Grande do Sul têm evidenciado ausência de resposta desta cultura à adubação potássica, mesmo em solos com baixo teor de potássio disponível. Este trabalho objetivou verificar a contribuição da mineralogia destes solos como fonte potencial de potássio para a cultura do arroz. Para tal, selecionaram-se quatro solos representativos das zonas orizícolas do estado do Rio Grande do Sul (Planossolo Hidromórfico, Planossolo Háplico, Gleissolo Háplico e Chernossolo Ebânico cultivados com arroz irrigado. Estes solos apresentam baixos teores de potássio trocável e não apresentam respostas à adubação potássica. Nas amostras dos horizontes A e B dos quatro solos, foram analisadas a granulometria e a composição química. A mineralogia das frações areia, silte e argila foi identificada por difratometria de raios-X. Os principais minerais fontes de potássio foram os seguintes: na fração areia, feldspatos e micas; nas frações silte e argila, feldspatos, micas, esmectitas e esmectitas com hidróxi-alumínio entrecamadas. A quantidade de potássio total, nas frações granulométricas, diferiu entre os solos. As frações silte e argila apresentaram os maiores teores de K-total, exceto para o Planossolo Háplico, que revelou maior reserva de potássio na fração areia. A ausência, ou a baixa resposta, à adubação potássica na cultura do arroz irrigado nesses quatro solos pode ser explicada pelos minerais fontes de potássio que ocorrem nesses solos.

    Full Text Available O bário (Ba é um metal alcalino terroso de ocorrência natural no solo. É constituinte de carbonatos, sulfatos e silicatos e ocorre como substituto isomórfico de elementos como Ca e K nos minerais. Quando disponível em elevados teores no solo, o Ba pode causar toxidez a diversos organismos vivos. Para considerar que determinado solo está livre de contaminação por esse elemento, faz-se necessário conhecer os teores de Ba nesse solo em condição natural. Portanto, a determinação de teores naturais de Ba em solos é essencial para a construção de uma legislação que sirva de base ao monitoramento e remediação de áreas contaminadas por esse elemento e que seja adequada à realidade pedológica local. Nesse contexto, o objetivo desta pesquisa foi determinar os teores naturais de Ba como base de referência de qualidade para os Solos de Referência do Estado de Pernambuco. Foram coletadas amostras dos dois primeiros horizontes dos 35 perfis de referência, as quais foram submetidas à digestão ácida em micro-ondas (método 3051A. Nos extratos obtidos foi efetuada a determinação dos teores de Ba por ICP-OES. Observaram-se teores de Ba superiores aos valores de prevenção e de investigação estabelecidos pela legislação brasileira (CONAMA, 2009, corroborando a necessidade de maior conhecimento das diversidades regionais para a elaboração de normas nacionais. Os teores naturais de Ba determinados nos solos podem ser utilizados como base para a definição dos valores de referência de qualidade para Ba nos solos de Pernambuco, de acordo com o preconizado pela legislação nacional.

    Full Text Available O sistema orgânico de produção deve resultar na utilização mais racional dos recursos naturais, sobretudo do solo. Os produtores orgânicos devem adotar práticas conservacionistas, além de atender a outros princípios deste sistema de produção. Neste trabalho foram avaliadas as práticas de manejo e conservação do solo adotadas por produtores orgânicos e convencionais nas regiões dos municípios de Socorro (Serra da Mantiqueira e Mogiana e Ibiúna, situados no Estado de São Paulo. O objetivo dessa pesquisa foi verificar o grau de adoção de práticas conservacionistas pelos produtores e avaliar a qualidade do solo na agricultura orgânica e convencional. Foi elaborado e aplicado um questionário, com visitas locais para verificação das práticas conservacionistas e ocorrência de erosão, em 30 propriedades. Os resultados foram expressos em índices indicadores de diversidade de uso do solo, atitude conservacionista, percepção de erosão e do impacto sobre os recursos hídricos. Foram também realizadas análises de atributos químicos, físicos e biológicos indicadores da qualidade do solo. Concluiu-se que os produtores orgânicos têm maior percepção quanto à atitude conservacionista e nas propriedades orgânicas há maior diversidade de cultivos, embora não haja maior diversidade geral de uso do solo. A produção orgânica de alface, em Ibiúna proporcionou maior atividade biológica no solo e maior colonização por fungos micorrízicos arbusculares. O sistema orgânico possui maiores teores de matéria orgânica e menores de potássio e não houve diferença entre os atributos físicos do solo dos sistemas orgânico e convencional.

O objetivo deste trabalho foi avaliar a capacidade de suporte de carga por meio da pressão de preconsolidação e sua dependência a conteúdo de água, densidade e carbono orgânico de um Argissolo Vermelho distrófico latossólico, após 18 anos de implantação de plantas de cobertura permanentes nas entrelinhas de um pomar de laranja. O delineamento experimental foi de blocos ao acaso, com três repetições. Foram estudados três tratamentos de manejo por meio de roçadas nas entrelinhas do pomar, desde o plantio do pomar em 1993: gramínea Paspalum notatum, leguminosa Arachis pintoi e vegetação espontânea. Cento e oito amostras indeformadas de solo foram coletadas em 2011 sob o rodado e entrerrodado das máquinas nas estrelinhas do pomar com textura arenosa nas camadas de 0,00-0,10 m (87 g kg-1 de argila e 0,10-0,20 m (122 g kg-1 de argila. Determinaram-se as pressões de preconsolidação das curvas de compressão do solo (25, 50, 100, 200, 400, 800 e 1.600 kPa em conteúdos de água sob três potenciais (-80, -330 e -1.000 hPa, a densidade do solo e o teor de carbono orgânico do solo. A pressão de preconsolidação não foi dependente do conteúdo de água, da densidade do solo e do teor de carbono orgânico do solo. A pressão de preconsolidação sob o rodado na camada de 0,00-0,10 m foi menor nos tratamentos leguminosa e vegetação espontânea. A manutenção permanente da gramínea manejada com roçadas nas entrelinhas do pomar de laranja proporcionou maior capacidade de suporte de carga do solo sob o rodado na camada superficial arenosa.

    Full Text Available Este trabalho teve por objetivos determinar a influência de diferentes métodos de preparo do solo sobre as perdas por erosão de metais pesados e avaliar a contaminação dos sedimentos e da água do córrego principal da microbacia de Caetés, município de Paty do Alferes (RJ. A avaliação foi realizada durante os meses de dezembro de 1996 a março de 1997, no ciclo de cultivo do pepino (Cucumis sativus L . Foram utilizadas parcelas do tipo Wischmeier, de tamanho de 22,0 x 4,0 m. Os tratamentos utilizados foram os seguintes: (a aração com trator morro abaixo e queimado (MAQ; (b aração com trator morro abaixo não queimado com restos de vegetação natural entre as linhas (MANQ; (c aração com tração animal em nível, faixas de capim-colonião a cada 7,0 m (AA, e (d cultivo mínimo, com preparo de covas em nível (CM. Avaliaram-se também os teores desses metais nos sedimentos de fundo e na água do córrego principal que drena a microbacia de Caetés. As perdas mais elevadas de metais pesados por erosão foram verificadas no tratamento MAQ, típico da região. Os sedimentos e a água do córrego da microbacia de Caetés mostraram incrementos nos teores totais de Cd, Ni, Pb, Zn e Mn de acordo com a posição de coleta na área. A água coletada no córrego e no açude apresentou concentrações de Cd, Mn e Pb acima dos padrões máximos estabelecidos para água potável. Os resultados obtidos neste trabalho permitem concluir que o uso intensivo de agroquímicos e as elevadas perdas de solo por erosão podem acarretar sérios riscos de contaminação da água do córrego da microbacia que é utilizada pelos animais e para irrigação.

    Full Text Available A fitorremediação é uma técnica que objetiva a descontaminação de solo e água, utilizando-se como agente de descontaminação plantas. É uma alternativa aos métodos convencionais de bombeamento e tratamento da água, ou remoção física da camada contaminada de solo, sendo vantajosa principalmente por apresentar potencial para tratamento in situ e ser economicamente viável. Além disso, após extrair o contaminante do solo, a planta armazena-o para tratamento subseqüente, quando necessário, ou mesmo metaboliza-o, podendo, em alguns casos, transformá-lo em produtos menos tóxicos ou mesmo inócuos. A fitorremediação pode ser empregada em solos contaminados por substâncias inorgânicas e/ou orgânicas. Resultados promissores de fitorremediação já foram obtidos para metais pesados, hidrocarbonetos de petróleo, agrotóxicos, explosivos, solventes clorados e subprodutos tóxicos da indústria. A fitorremediação de herbicidas apresenta bons resultados para atrazine, tendo a espécie Kochia scoparia revelado potencial rizosférico para fitoestimular a degradação dessa molécula. Embora ainda incipiente no Brasil, já existem estudos sobre algumas espécies agrícolas cultivadas e espécies silvestres ou nativas da própria área contaminada, com o objetivo de selecionar espécies eficientes na fitorremediação do solo.Phytoremediation is a technique that uses plants as agents of soil and water decontamination. It is an advantageous alternative to the conventional methods of water pumping and treatment and/or physical removal of the contaminated soil layer since it allows in situ treatment at feasible costs. Also, after extracting the contaminant from the soil, the plant stores it for a subsequent treatment, if necessary, or may metabolically transform it into products that are less or non-toxic. Phytoremediation can be employed in soils contaminated by inorganic or organic substances. Promising phytoremediation results have

    Full Text Available Tendo como objetivo avaliar a eficiência relativa do superfosfato simples (SS, fosfato parcialmente acidulado (FAPS e termofosfato magnesiano (TERM como fonte de P e outros nutrientes para o cultivo de plantações de eucalipto, em dois solos da região dos Cerrados, uma areia quartzosa (50 g kg-1 de argila álica e um latossolo vermelho-escuro (230 g kg-1 de argila álico, foi realizado este experimento, sob condições de casa de vegetação, na ESALQ/USP, Piracicaba (SP, em 1993. Subamostras do AQ receberam 0, 75, 150 e 300 mg kg-1 de P e, do LE, 0, 125, 250 e 500 mg kg-1 de P no solo. As doses de P foram estimadas com base na solubilidade dos adubos; SS e FAPS, em citrato de amônio, e TERM, em ácido cítrico 20 g L-1. Em cada vaso (5 kg de solo, deixou-se uma planta de Eucalyptus grandis por 90 dias após a emergência e desbaste das plântulas. Paralelamente ao experimento em casa de vegetação, subamostras de todos os tratamentos, com 2 kg de solo, foram incubadas no interior de sacos plásticos por 0, 10, 20, 40, 60 e 80 dias. Ao término de cada período de incubação, os solos eram amostrados e analisados. Mediante o cálculo de índices de eficiência relativa entre os adubos, verificou-se que o TERM foi superior 64% ao SS e 57% ao FAPS no solo AQ. No LE, o SS foi superior 55% ao TERM e 34% ao FAPS. O TERM foi a fonte de P que promoveu os maiores acréscimos do nível de fertilidade dos solos, com expressiva elevação do pH do solo, redução das concentrações de Al e aumento daquelas de Ca e Mg. Os ganhos de produção das mudas de eucalipto foram altamente correlacionados com a absorção de P, K, Ca, Mg e Zn. O TERM proporcionou as maiores absorções desses nutrientes no solo AQ e, as menores, de P, Ca e Zn no LE. As distintas respostas de crescimento para os adubos avaliados, em ambos os solos, sobretudo para TERM e SS, foram atribuídas, em grande parte, aos efeitos secundários das fontes de P sobre a fertilidade dos

    Full Text Available A unique eye color, called tiger-eye, segregates in the Puerto Rican Paso Fino (PRPF horse breed and is characterized by a bright yellow, amber, or orange iris. Pedigree analysis identified a simple autosomal recessive mode of inheritance for this trait. A genome-wide association study (GWAS with 24 individuals identified a locus on ECA 1 reaching genome-wide significance (Pcorrected = 1.32 × 10−5. This ECA1 locus harbors the candidate gene, Solute Carrier Family 24 (Sodium/Potassium/Calcium Exchanger, Member 5 (SLC24A5, with known roles in pigmentation in humans, mice, and zebrafish. Humans with compound heterozygous mutations in SLC24A5 have oculocutaneous albinism (OCA type 6 (OCA6, which is characterized by dilute skin, hair, and eye pigmentation, as well as ocular anomalies. Twenty tiger-eye horses were homozygous for a nonsynonymous mutation in exon 2 (p.Phe91Tyr of SLC24A5 (called here Tiger-eye 1, which is predicted to be deleterious to protein function. Additionally, eight of the remaining 12 tiger-eye horses heterozygous for the p.Phe91Tyr variant were also heterozygous for a 628 bp deletion encompassing all of exon 7 of SLC24A5 (c.875-340_1081+82del, which we will call here the Tiger-eye 2 allele. None of the 122 brown-eyed horses were homozygous for either tiger-eye-associated allele or were compound heterozygotes. Further, neither variant was detected in 196 horses from four related breeds not known to have the tiger-eye phenotype. Here, we propose that two mutations in SLC24A5 affect iris pigmentation in tiger-eye PRPF horses. Further, unlike OCA6 in humans, the Tiger-eye 1 mutation in its homozygous state or as a compound heterozygote (Tiger-eye 1/Tiger-eye 2 does not appear to cause ocular anomalies or a change in coat color in the PRPF horse.

    Full Text Available En este trabajo se describen los procedimientos aplicados en el rescate, conservación y almacenaje de la colección bioarqueológica del sitio Paso Alsina 1 (Pdo. de Patagones, Prov. de Buenos Aires. Se recuperaron 10 entierros secundarios múltiples en un área de aproximadamente 6 m2. Análisis cuantitativos indicaron la presencia de ca. 3500 unidades anatómicas, correspondientes a un NMI de 56 individuos, representados por ambos sexos y diferentes categorías etarias. El hallazgo fortuito del sitio y la complejidad de la estructura funeraria datada en ca. 500 años AP llevaron a tomar una serie de decisiones metodológicas y técnicas ligadas al rescate de los entierros. Trabajos de laboreo con maquinarias agrícolas dejaron unidades anatómicas parcialmente expuestas y fragmentadas sobre la superficie del terreno. A partir de los hallazgos se desarrollaron tres campañas de excavación en el lapso de un año, recuperándose la totalidad de las inhumaciones. Durante los trabajos de campo se realizaron tareas de conservación preventivas (cobertura de los entierros por excavar y actividades de intervención (uso de consolidantes como resina de acetato de polivinilo o PVAc. En la mayoría de los casos, se procedió a la extracción de huesos individuales y cuando fue posible, los entierros se recuperaron en bloques. En el laboratorio se llevaron a cabo tareas de conservación y restauración de los elementos óseos. Actualmente, la muestra se encuentra acondicionada y almacenada, en bolsas y cajas libres de ácido, en gabinetes móviles dentro de un depósito con condiciones de temperatura y humedad estables. Esta serie de procedimientos permitió mantener la integridad del registro óseo para su posterior estudio bioarqueológico.

MATERIAL Y MÉTODOS: Estudio cualitativo donde se realizaron 40 entrevistas en profundidad a PVVIH en cuatro estados del país. Resultados. Vivir con VIH sin apoyo ni consejería limita el ejercicio de los derechos sexuales y reproductivos, especialmente en las mujeres. Las principales limitantes son sentimientos de frustración, falta de claridad en la información, temor a la reinfección, falta de poder para negociar el uso del condón, estigma, discriminación y falta de acceso a servicios y tecnología adecuados. CONCLUSIÓN: Para una mayor conciencia y ejercicio de los derechos de las PVVIH se necesita promover la educación sexual, cambios culturales que combatan la desigualdad de género, el estigma y la discriminación, e información oportuna y científica sobre prevención del VIH.OBJECTIVE: To analyze experiences of heterosexual Mexican people living with HIV (PLWHA related to the exercise of their sexual and reproductive rights. MATERIAL AND METHODS: Qualitative study based on 40 in-depth interviews with PLWHA in four Mexican States. RESULTS: Lack of support and counseling limits the exercise of sexual and reproductive rights by PLWHA, especially women. Principal limitations include feelings of frustration and confusion, fear of re-infection, scanty information, lack of power to negotiate condom use, social stigma and discrimination, and limited access to services and adequate technologies. CONCLUSION: To increase awareness and exercise of rights by PLWHA it is necessary to: improve sexual education; promote processes of cultural change to combat gender inequality and stigma and discrimination; and provide timely and scientific information about HIV prevention.

For this purpose, companies within the Spanish Stock Exchange lndex, IBEX 35, have been considered as a sample, assuming that they do offer adequate quality standard s when providing the information requested. The empirical evidence is obtained through the identification and temporary and space exploration of the qualitative attributes of the environmental data appearing in the accounting statements published by such companies from 1998 to 2002. The results obtained show, among others, the low quality in the information supplied that, in certain occasions, may arise from lacks in the accounting regulations on the recognition of environmental factors in the financial statements.

    This paper aims to describe and analyze the application of a specific participative methodology - called Rapid Participative Diagnosis (PRA -Participatory Rapid Appraisal) - to the development of a diagnosis for defining socio-environmental compensation projects for oil and gas exploration efforts involving nine fishing communities from lower southern Bahia State in Brazil. It has sought to identify the feasibility in applying this methodology within that context. This study leads to the conclusion that the application of Participative Diagnosis to the definition of socio-environmental compensation projects should open new horizons not only for the communities but also for everyone else involved. However, the monitoring of such kind of process requires outstanding and specific care to insure a satisfactory program implementation in order to avoid expectations and frustrations. The El Paso's DRP was a new experience for all the sectors involved: the environmental agency, the oil company, the government, several institutions and communities. The steps followed drew up the communities' reality and their relationship with the other participants. It was a work of citizenship and democracy, whose impressive results justified all the effort made. (author)

    This article is based on an assessment that indicates the low effectiveness of the actions and programmes of social responsibility to the less impact than in business and should not build the value they expected. Focussing on this issue in cases of relationship between oil and gas companies with fishing communities, the scene of conflict is chronic and there is a fragile relationship in terms of confidence. It has been further that the approaches and methods commonly used are not properly aligned to the realities and characteristics of artisanal fisheries. In this context, we present an innovative process of relationship between the company El Paso Oil and Gas of Brazil and fishing communities in the region of Baixo-Sul, Bahia. The strategy used effectively consolidated the relationship of confidence between the company and the fishing communities around the area of exploration, rescuing the self-esteem, alleviate the marginalisation and making visible a productive sector of extreme importance. Furthermore, the capabilities and skills, both communities as the government and other companies to take more solid and ongoing commitments in the process of co-management require specific efforts in the strengthening of an institutional arrangement and the formation of social capital to continue advancing in concept work.

    Full Text Available O problema de compactação do solo vem aparecendo sistematicamente na região do Cerrado, onde os sistemas convencionais de manejo do solo têm causado desagregação excessiva da camada arável, o encrostamento superficial e a formação de camadas coesas ou compactadas (pé-de-grade ou pé-de-arado. Como alternativa, os agricultores adotaram o Sistema Plantio Direto; entretanto, em várias situações vêm sendo relatadas ocorrências de aumento da densidade do solo e diminuição da macroporosidade, o que tem sido diagnosticado como compactação, fazendo com que o agricultor seja obrigado a movimentar o solo. Este trabalho teve por objetivo verificar como a compactação do solo afeta as suas propriedades físicas e de transmissão de água. Para isto, utilizaram-se colunas de solo compactadas artificialmente, para produzir densidades do solo de 1,0; 1,2; 1,4 e 1,6 kg dm-3. As propriedades de transmissão de água foram determinadas com infiltrômetros de tensão, para as cargas de pressão de -0,5; -2,0 e -6,0 cm de água. O aumento da densidade do solo aumentou sua resistência à penetração e reduziu linearmente a porosidade total e a macroporosidade. Houve ainda, redução no tamanho dos poros para o fluxo de água, reduzindo a condutividade hidráulica do solo. Esta redução foi mais acentuada na maior carga de pressão testada. Com a carga de pressão de -2,0 cm de água, a redução no tamanho dos poros foi parcialmente compensada com aumento do seu número. O método do infiltrômetro de tensão mostrou-se adequado em distinguir diferenças nas propriedades de transmissão de água de um solo submetido a diferentes níveis de compactação.Soil compaction is a problem in the Savanna region, where conventional soil tillage systems have caused excessive disaggregation of the arable layer, superficial crusts, and compacted subsuperficial layers. As an alternative, the farmers have adopted the no-tillage system. However, in various

    Full Text Available O presente trabalho foi realizado com a finalidade de estabelecer um sistema e técnica mais adequados de se coletar amostras de terra, para fins de estudo de fertilidade. Foram escolhidas duas áreas de solos diferentes. Uma delas com seis hectares, situada na Estação Experimental de Ribeirão Prêto, em solo tipo terra roxa legítima ; a outra com quatro hectares e localizada na Fazenda Santa Maria, em Pindorama, em solo do tipo arenito Bauru. A retirada das amostras de cada área foi feita com tubos especialmente construídos para esse fim e obedeceu ao seguinte critério: 1 30 amostras simples, cobrindo tôda a área ; 2 10 amostras compostas, formadas de cinco amostras simples, cobrindo tôda a área. 3 5 amostras compostas, formadas de 20 amostras simples, cobrindo tôda a área. Nessas amostras foram determinados : pH, carbono total, potássio "trocável" e cálcio "trocável". Diante dos dados obtidos e levando-se em conta o trabalho exigido no laboratório, aconselha-se a retirada de três amostras compostas formadas de 20 simples cada uma, em glebas uniformes, de cinco hectares aproximadamente.The following methods of collecting soil samples for fertility studies were compared : 1 thirty individual samples covering the whole area ; 2 ten composite samples, each consisting of five individual samples, covering the whole area ; 3 five composite samples, each consisting of 20 individual samples, covering the whole area. The three types of samples were collected in each of two plots : 1 a six-hectare plot in the Estação Experimental de Ribeirão Prêto, representing the "terra roxa" soil; 2 a four-hectare plot in the Santa Maria Farm, Pindorama, where the soil is of the "arenito de Bauru" type. The pH, total carbon, and exchangeable potassium and calcium were determined in the samples. Based on data obtained in the present investigation and considering the amount of work involved in the routine laboratory tests, it is suggested that

    Full Text Available Foram estudados dois perfis de solos com problemas de sodicidade (Planossolo Solódico e Solonetz-Solodizado, no estado do Ceará, com o objetivo de conhecer a mineralogia das frações areia, silte e argila e os processos de alterações que ocorrem nos respectivos minerais. A areia e o silte grosso foram avaliados por microscopia de polarização e contraste de fase, enquanto o silte fino e a argila foram analisados por difração de raios-X. Utilizou-se, ainda, a microscopia eletrônica de varredura para obtenção de informações complementares sobre as transformações mineralógicas ocorridas nos horizontes dos dois perfis. Verificou-se que o Planossolo Solódico apresenta na fração argila quantidades mais ou menos equivalentes de caulinita e montmorilonita no horizonte 2Btn, o mesmo acontecendo com as proporções de caulinita e vermiculita no horizonte A. Nas outras frações, foram encontrados teores variáveis de quartzo, plagioclásios, hornblenda e biotita. Por sua vez, o Solonetz-Solodizado mostrou uma fração argila essencialmente caulinítica ao longo de todo o perfil e com quantidades variáveis de quartzo, feldspato e biotita nas outras frações. Em ambos os perfis, o enriquecimento de argila no Bt resultou essencialmente das alterações "In situ" dos minerais primários intemperizáveis contidos na rocha subjacente. A hipótese de alternância de processos de oxi-redução nos horizontes A e, ou, E, em razão da baixa permeabilidade do horizonte 2Btn, provocando um processo de ferrólise naqueles horizontes, é também uma alternativa de gênese que não pode ser descartada para explicar o alto contraste textural desses solos. O intemperismo da albita e de outros plagioclásios ricos em sódio, o clima semi-árido, e a drenagem impedida são os fatores condicionantes dos percentuais elevados de sódio, observados nos dois pedons. Também nos dois solos, os teores destoantes de quartzo, a geomorfologia da região e a

    Full Text Available A ordem Isoptera é bastante conhecida pelo seu potencial como praga, apesar dos cupins-praga constituírem a minoria dentro do grupo. Os cupins (térmitas são invertebrados dominantes em ambientes terrestres tropicais e estão espalhados desde as florestas úmidas até as savanas, sendo encontrados até mesmo em regiões áridas, nos mais variados habitats. Esses insetos têm um papel destacado e ainda pouco estudado nos ecossistemas tropicais. Ciclagem de nutrientes, aeração, infiltração de água do solo, bioturbação, formação de agregados e decomposição de material orgânico, são processos influenciados pela ação dos térmitas, que vão, direta ou indiretamente, influenciar a formação dos solos e da paisagem onde se encontram. Sugerimos que uma maior abordagem deva ser dirigida em futuras pesquisas para a influência desses insetos no solo sob condições específicas de uso e manejo, na produção sustentável de alimentos e nas mudanças climáticas.The order Isoptera is well known by its potential as a plague, although the number of species that are plagues is small within the group. Termites are the dominant invertebrates in tropical terrestrial environments and are spread from tropical rainforests to the savannahs, being found even in arid regions, in various habitats. These insects have a major role and are still little studied in tropical ecosystems. Nutrient cycling, aeration, water infiltration of soil, bioturbation, aggregates formation and organic material decomposition, are processes influenced by the action of termites, which , directly or indirectly, affect soil and landscape formation wherever they are. We suggest that a better approach must be addressed in future researches about these insects influence in the soil under specified conditions of use and management, in sustainable food production and climate changes.

    To report our institutional experience and long-term results with the Freedom Solo bovine pericardial stentless bioprosthesis (Sorin Group, Saluggia, Italy). Between January 2005 and November 2009, 149 patients (mean age, 73.6 ± 8.7 years; 68 [45.6%] female) underwent isolated (n = 75) or combined (n = 74) aortic valve replacement (AVR) using the Solo in our institution. Follow-up was 100% complete with an average follow-up time of 5.9 ± 2.6 years (maximum, 9.6 years) and a total of 885.3 patient years. Operative (30-day) mortality was 2.7% (1.3% for isolated AVR [n = 1] and 4.0% for combined procedures [n = 3]). All causes of death were not valve-related. Preoperative peak (mean) gradients of 74.2 ± 23.0 mm Hg (48.6 ± 16.3 mm Hg) decreased to 15.6 ± 5.4 mm Hg (8.8 ± 3.0 mm Hg) after AVR, and remained low for up to 9 years. The postoperative effective orifice area was 1.6 ± 0.57 cm(2), 1.90 ± 0.45 cm(2), 2.12 ± 0.48 cm(2), and 2.20 ± 0.66 cm(2) for the valve sizes 21, 23, 25, and 27, respectively, with absence of severe prosthesis-patient mismatch and 0.7% (n = 1) experienced moderate prosthesis-patient mismatch. During follow-up, 26 patients experienced structural valve deterioration (SVD) and 14 patients underwent explantation. Kaplan-Meier estimates for freedom from death, explantation, and SVD at 9 years averaged 0.57 (range, 0.47-0.66), 0.82 (range, 0.69-0.90), and 0.70 (range, 0.57-0.79), respectively. The Freedom Solo stentless aortic valve is safe to implant and shows excellent early and midterm hemodynamic performance. However, SVD was observed in a substantial number of patients after only 5-6 years and the need for explantation increased markedly, suggesting low durability.
