Conforto térmico de búfalas em sistema silvipastoril na Amazônia Oriental

O objetivo deste trabalho foi avaliar o efeito de um sistema silvipastoril no conforto térmico de 20 búfalas Murrah, das quais 10 criadas em piquetes sem sombra (SS) e 10 com sombreamento (CS) de Racosperma mangium, em Belém, PA. Os animais foram alimentados em pasto, com Urochloa humidicola, com acesso livre à água para beber e sal mineral. A cada três dias, foram mensuradas: temperatura do ar (TA), umidade relativa do ar (UR), temperatura de globo negro (TGN), temperatura retal (TR), frequências respiratória (FR) e cardíaca (FC), e a temperatura da superfície corporal (TSC), pela manhã (7h) e à tarde (13h). Os valores de TR, TSC, FR e FC foram maiores à tarde, especialmente no grupo SS. Mais altas no período menos chuvoso, a TR, TSC e FR apresentaram correlação linear positiva com a TA e o índice de temperatura e umidade (ITGU) e negativa com a UR. Tanto na estação mais chuvosa quanto na menos chuvosa, a FC apresentou correlações significativas positivas com a TA e ITGU e negativas com a UR, apenas no período mais chuvoso. A arborização da pastagem é eficiente para melhorar o conforto térmico das búfalas Murrah, principalmente à tarde.

Molecular characterization of a human matrix attachment region epigenetic regulator.

Matrix attachment regions (MAR) generally act as epigenetic regulatory sequences that increase gene expression, and they were proposed to partition chromosomes into loop-forming domains. However, their molecular mode of action remains poorly understood. Here, we assessed the possible contribution of the AT-rich core and adjacent transcription factor binding motifs to the transcription augmenting and anti-silencing effects of human MAR 1-68. Either flanking sequences together with the AT-rich core were required to obtain the full MAR effects. Shortened MAR derivatives retaining full MAR activity were constructed from combinations of the AT-rich sequence and multimerized transcription factor binding motifs, implying that both transcription factors and the AT-rich microsatellite sequence are required to mediate the MAR effect. Genomic analysis indicated that MAR AT-rich cores may be depleted of histones and enriched in RNA polymerase II, providing a molecular interpretation of their chromatin domain insulator and transcriptional augmentation activities.

High prevalence of forgoing healthcare for economic reasons in Switzerland: a population-based study in a region with universal health insurance coverage.

OBJECTIVE: To investigate the determinants and the 4-year evolution of the forgoing of healthcare for economic reasons in Switzerland. METHOD: Population-based survey (2007-2010) of a representative sample aged 35-74years in the Canton of Geneva, Switzerland. Healthcare forgone, socioeconomic and insurance status, marital status, and presence of dependent children were assessed using standardized methods. RESULTS: A total of 2601 subjects were included in the analyses. Of the subjects, 13.8% (358/2601) reported having forgone healthcare for economic reasons, with the percentage varying from 3.7% in the group with a monthly income ≥13,000CHF (1CHF≈1$) to 30.9% in the group with a monthly income <3000CHF. In subjects with a monthly income <3000CHF, the percentage who had forgone healthcare increased from 22.5% in 2007/8 to 34.7% in 2010 (P trend=0.2). Forgoing healthcare for economic reasons was associated with lower income, female gender, smoking status, lower job position, having dependent children, being divorced and single, paying a higher deductible, and receiving a premium subsidy. CONCLUSION: In a Swiss region with universal health insurance coverage, the reported prevalence of forgoing healthcare for economic reasons was high and greatly dependent on socioeconomic factors. Our data suggested an increasing trend among participants with the lowest income.

Les monedes en els contextos funeraris del suburbi oriental de Tàrraco: més enllà de Caront

La deposició de moneda a les tombes és un fenomen conegut i àmpliament debatut entre els especialistes. Comunament interpretada com a oferta votiva i enquadrada dins la genètica definició d'"òbol de Caront", la moneda ha estat un element d'aixovar poc estudiat i analitzat superficialment. A través de l'article es pretén examinar des d'una posició crítica aquest fest a partir de la documentació de les monedes trobades en contextos funeraris en el suburbi oriental de la ciutat de Tàrraco. A través del reexàmen de les monedes és possible una aproximació més realista i sensible a la gran variabilitat formal dels rituals funeraris d'època romana.

Distributed Energy Production in the North-West Region of Russia

The energy system of Russia is the world's fourth largest measured by installed power. The largest are that of the the United States of America, China and Japan. After 1990, the electricity consumption decreased as a result of the Russian industry crisis. The vivid economic growth during the latest few years explains the new increase in the demand for energy resources within the State. In 2005 the consumption of electricity achieved the maximum level of 1990 and continues to growth. In the 1980's, the renewal of power facilities was already very slow and practically stopped in the 1990's. At present, the energy system can be very much characterized as outdated, inefficient and uneconomic because of the old equipment, non-effective structure and large losses in the transmission lines. The aim of Russia's energy reform, which was started in 2001, is to achieve a market based energy policy by 2011. This would thus remove the significantly state-controlled monopoly in Russia's energy policy. The reform will stimulateto decrease losses, improve the energy system and employ energy-saving technologies. The Russian energy system today is still based on the use of fossil fuels, and it almost totally ignores the efficient use of renewable sources such as wind, solar, small hydro and biomass, despite of their significant resources in Russia. The main target of this project is to consider opportunities to apply renewable energy production in the North-West Federal Region of Russia to partly solve the above mentioned problems in the energy system.

Jurassic and Early Cretaceous Radiolaria of the Lower Amurian Terrane: Khabarovsk region, far east of Russia

New data on biostratigraphy, sedimentology and tectonics of the Russian Far Eastern region (Lower Amurian terrane) are presented. This study shows that sedimentary sequence of the terrane consists of interbedded Radiolaria-bearing siliceous and volcaniclastic sediments spanning an interval of over 90 million years. It is shown that accumulation of radiolarian deposits on an oceanic plate was associated with alkaline (intraplate) volcanism in the Jurassic, while the plate was drifting, and with some are volcanism during the Early Cretaceous. The younger siliceous rocks contain volcaniclastic material and indicate that the studied sequence approached the trench in the Early Cretaceous (Hauterivian-Barremian) and became accreted in the late Albian-early Cenomanian. We describe and illustrate radiolarian species extracted fi om 21 samples. A taxonomic list of 194 taxa and nine plates of Jurassic-Early Cretaceous Radiolaria are presented.

Cross-Sectional and Longitudinal Associations between Body Mass Index and Cardiometabolic Risk Factors in Adolescents in a Country of the African Region.

We assessed the association between several cardiometabolic risk factors (CRFs) (blood pressure, LDL-cholesterol, HDL-cholesterol, triglycerides, uric acid, and glucose) in 390 young adults aged 19-20 years in Seychelles (Indian Ocean, Africa) and body mass index (BMI) measured either at the same time (cross-sectional analysis) or at the age of 12-15 years (longitudinal analysis). BMI tracked markedly between age of 12-15 and age of 19-20. BMI was strongly associated with all considered CRFs in both cross-sectional and longitudinal analyses, with some exceptions. Comparing overweight participants with those having a BMI below the age-specific median, the odds ratios for high blood pressure were 5.4/4.7 (male/female) cross-sectionally and 2.5/3.9 longitudinally (P < 0.05). Significant associations were also found for most other CRFs, with some exceptions. In linear regression analysis including both BMI at age of 12-15 and BMI at age of 19-20, only BMI at age of 19-20 remained significantly associated with most CRFs. We conclude that CRFs are predicted strongly by either current or past BMI levels in adolescents and young adults in this population. The observation that only current BMI remained associated with CRFs when including past and current levels together suggests that weight control at a later age may be effective in reducing CRFs in overweight children irrespective of past weight status.

Poblament i estructuració del territori a la comarca del Vallès Oriental: una proposta metodològica

Landscape research in urban or peri-urban areas implies important methodological constraints. In this sense, the area of study, placed in the Vallès basin, near the city of Barcelona, has known an important process of landscape’s transformation in the last two decades. This fact restrains the retrieving of archaeological data and the development of archaeological surveys and fieldwalking. The destruction of large agrarian areas implies that landscape morphology research must focus on an intensive work with historical cartography and old aerial photography within a GIS environment.

Análisis arqueomorfológico y dinámica territorial en el Vallés Oriental (Barcelona) de la Protohistoria s. VI-V a.C.) a la alta Edad Media (s. IX-X)

La investigación sobre el paisaje en zonas urbanas o periurbanas implica importantes limitaciones metodológicas. En el presente estudio, el trabajo se centra en un llano pre-litoral próximo a la ciudad de Barcelona, el Vallès Oriental, profundamente urbanizado en las últimas dos décadas, hecho que condiciona la recuperación de nuevos datos arqueológicos y la implementación de programas de prospección arqueológica. Asimismo, la particular topografía que presenta el llano, caracterizado por unos relieves suaves, ha obligado a adaptar la metodología del análisis arqueomorfológico a este contexto geográfico. El artículo presenta los resultados del análisis arqueomorfológico realizado, que han sido cruzados con la documentación histórica y arqueológica para caracterizar —desde una perspectiva diacrónica— la red viaria, la estructuración territorial y la evolución del poblamiento de esta área y, finalmente, determinar las dinámicas del paisaje en época romana. La investigación sobre la morfología del territorio se ha llevado a cabo a partir de un intenso trabajo de fotointerpretación y análisis de la cartografía histórica en entorno SIG, especialmente útil en un paisaje marcado por las importantes trasformaciones del medio rural. Igualmente, los datos generados en los últimos años por la investigación arqueológica han sido revisados de forma detallada, a fin de contribuir a la planificación de las prospecciones arqueológicas y arqueomorfológicas desarrolladas.
