1. Hypercapnia attenuates ventilator-induced lung injury through vagus nerve activation
Abstract Purpose: To investigate the role of vagus nerve activation in the protective effects of hypercapnia in ventilator-induced lung injury (VILI) rats. Methods: Male Sprague-Dawley rats were randomized to either high-tidal volume or low-tidal volume ventilation (control) and monitored for 4h. The high-tidal volume group was further divided into either

2. PHNSNCL4-N SUPPORTED ON ACTIVATED CARBON AS NOVEL TIN-BASED CATALYSTS FOR ACETYLENE HYDROCHLORINATION
In this work, a series of PhnSnCl4-n (n = 1, 2, 3, and 4) based catalysts were prepared by incipient wetness impregnation using activated carbon (AC) as support and triphenyltin chloride (Ph3ClSn) and tin(IV) chloride (SnCl4) as Sn precursors. The obtained catalysts were systematically characterized by X-ray diffraction (XRD), N2 physisorption, Scanning elec

4. Species composition and temporal activity of Arctiinae (Lepidoptera: Erebidae) in two cerrado vegetation types
Arctiinae moths include nearly 11,000 species worldwide, of which approximately 700 species occur in the Brazilian Cerrado. The aim of this study was to describe the species composition of Arctiinae, as well as the variation in annual and nightly moth activity, in two Cerrado vegetation types. We sampled moths one night per month from September 2008 to June

6. Hourly activity of Lutzomyia neivai in the endemic zone of cutaneous leishmaniasis in Tucumán, Argentina: preliminary results
In the present work, the hourly activity of Lutzomyia neivai was studied in the southern part of the province of Tucumán, Argentina, in an area of transmission of cutaneous leishmaniasis during two months of higher activity. In addition, the variables that influenced the abundance of Lu. neivai were evaluated. A total of 1,146 individuals belonging to Lu. n

7. The population ecology of Muscina stabulans (Fallén) (Diptera: Muscidae), along an Urban-Rural Gradient of Buenos Aires, Argentina
The false stable fly, Muscina stabulans (Fallén), was surveyed along an urban-rural gradient at Almirante Brown, Buenos Aires province, Argentina. Samples were taken at monthly intervals from May 2005 to April 2007. Hourly captures of adult flies (10:00 am - 04:00 pm) were taken at each sampling date with a hand net. The baits used were 250 g of rotten cow

8. Physical activity, absenteeism and the need for health care by automotive industry employees from São Caetano do Sul / Atividade física, absenteísmo e demanda por atendimento à saúde de funcionários de indústria automobilística de São Caetano do Sul
Background: By fostering physical activities and healthy life behavior, one can prevent chronic diseases. The health-related costs represent a heavy burden not only to the governmental entities but also to some private companies with many different levels of activities. The main objective of this study was to verify the association between absenteeism due to

9. Atmospheric patterns associated with concentrations of tropospheric ozone in the metropolitan region of Sao Paulo / Padrões atmofésricos associados a concentrações de ozônio troposférico na região metropolitana de São Paulo
In the past few years, tropospheric ozone has been noticed to exceed the states environmental agency (CETESB) air quality standards more than any other air pollutant in the Sao Paulo Metropolitan Area (SPMA), Brazil. Its assumed that different atmospheric patterns are responsible for different impacts on ozone concentrations, due to already known phenomena c

10. SPATIAL AND TEMPORAL DISTRIBUTION OF SOYBEAN STINK BUG AND BEHAVIOR OF Piezodorus guildinii (WESTWOOD, 1837) (HEMIPTERA: PENTATOMIDAE) ON SOYBEAN (Glycine max (L.) MERRILL) ON DAY TIME / DISTRIBUIÇÃO ESPACIAL E TEMPORAL DE PERCEVEJOS DA SOJA E COMPORTAMENTO DE Piezodorus guildinii (WESTWOOD, 1837) (HEMIPTERA: PENTATOMIDAE) NA SOJA (Glycine max (L.) MERRILL) AO LONGO DO DIA
From december 2006 to april 2008 was conducted a experiment at Universidade Federal de Santa Maria, Santa Maria, RS, Brasil, with objective to verify spatial and temporal distribution of soybean stink bug, with georeferenced surveying. The samplings was accomplished in area of 6,64 hectares of soybean (Glycine max (L.) Merrill), it was divided in a sample gr

11. Abundância e diversidade de filostomídeos (Chiroptera/Phyllostomidae) em quatro fragmentos da Zona da Mata Mineira e horário de atividade de seis espécies de morcegos em dois fragmentos florestais urbanos
A fragmentação e alteração dos remanescentes florestais são colocadas como as principais causas da diminuição da diversidade dos morcegos neotropicais, porém ainda existem poucos estudos sobre os efeitos da diminuição e alteração dos habitats nas comunidades de morcegos, bem como esses animais estão explorando os recursos das áreas onde vivem.

12. Cosmic ray anisotropy and solar activity
In this paper an attempt is made to study the occurrence of a large number of high amplitude anisotropic wave train events in cosmic ray intensity during 1981-1994 and to identify a possible correlation with solar activity using the hourly neutron monitor data of Deep River station. The diurnal time of maximum for both HAE as well as for all days is found to
