VUV Fourier-transform absorption study of the Lyman and Werner bands in D2

An extensive survey of the D2 absorption spectrum has been performed with the high-resolution VUV Fourier-transform spectrometer of the DESIRS beamline at the SOLEIL synchrotron. The frequency range of 90 000-119 000 cm-1 covers the full depth of the potential wells of the B 1{\Sigma}+u, B' 1{\Sigma}+u, and C 1{\Pi}u electronic states up to the D(1s) + D(2\ell) dissociation limit. Improved level energies of rovibrational levels have been determined up to respectively v = 51, v = 13, and v = 20. Highest resolution is achieved by probing absorption in a molecular gas jet with slit geometry, as well as in a liquid helium cooled static gas cell, resulting in line widths of ~0.35 cm-1. Extended calibration methods are employed to extract line positions of D2 lines at absolute accuracies of 0.03 cm-1. The D1{\Pi}u and B" 1{\Sigma}+u electronic states correlate with the D(1s) + D(3\ell) dissociation limit, but support a few vibrational levels below the second dissociation limit, respectively v = 0-3 and v = 0-1, and are also included in the presented study. The complete set of resulting level energies is the most comprehensive and accurate data set for D2. The observations are compared with previous studies, both experimental and theoretical.Comment: 13 pages, 6 figures. The second set of Tables (Tables I-IV after the references), is auxiliary materia

Total and labile organic carbon content in agroecological system.

In an intercropping lettuce-carrot system submitted to crescent dosages of organic compost (0; 12; 24; 48 Mg ha-1) were monitored carbon from soil microbial biomass (MBC), labile carbon in fumigated soil (LCF), in non-fumigated soil (LCNF), in autoclaved soil (LCA) and total organic carbon (TOC) at 0-10 cm of depth. Pasture and forest areas surrounding the experiment were used as reference. Five samples from soil were evaluated at 8 days before the beginning of the experiment, 0; 6; 60 and 114 days after manuring (dam). LCF was the attribute that presented the most consistent correlation with TOC that is usually utilized to detect changes in soil organic matter. Increasing dosages of organic compost caused the increase of MBC, LCF, LCNF, LCA and TOC. From 60 days after planting and forward, MBC and LCF presented decrease of their levels according to the quality of organic compost. Pasture and forest soils behave as contrasts, holding lower and higher content of carbon of soil, respectively

Ocorrências de trânsito com motocicleta e sua relação com a mortalidade

This study characterizes traffic accidents involving motorcycles according to local conditions, data concerning the type of accident, date and time, and identifies among these variables those associated with the death of victims. This retrospective study uses data from traffic collision reports from 2004 and death records from the institute of forensic medicine. A total of 99.4% of the events occurred in urban areas, where illumination (87.4%), weather conditions (80.6%); and traffic signs (70.6%) were satisfactory. Collisions between motorcycles and cars or pickup trucks prevailed (55.5%), followed by motorcycle falls (18.0%). In relation to the type of collision, the highest percentage was observed in broadside collision category (35.2%). There were differences between the groups of fatalities and survivors in relation to the area and illumination in the collisions site, in addition to the types of collision and impact. The conclusion is that local conditions and types of collision and impact stand out among the multiple variables defining the severity of accidents involving motorcycles.Se tuvo por objetivo caracterizar las ocurrencias de tránsito con motocicleta, según condiciones locales, datos relacionados al tipo de accidente, fecha y hora, además de identificar entre esas variables las que se asociaron con la muerte de las víctimas. Se trata de un estudio retrospectivo utilizando datos de los Boletines de Ocurrencia de Tránsito referentes al año de 2.004 y los registros de muerte del Instituto Médico Legal. El 99,4% de las ocurrencias sucedieron en área urbana, en locales donde las condiciones de luminosidad (87,4%), condición meteorológica (80,6%) y señalización (70,6%) eran satisfactorias. Predominó la colisión de motocicleta con automóvil o camioneta (55,5%) y las caídas de motocicleta fueron las más frecuentes (18,0%). En el tipo de impacto, el mayor porcentaje fue observado en la categoría colisión transversal (35,2%). El grupo de muertos difirió en relación a los sobreviventes en cuanto al área y luminosidad del local de la ocurrencia, además del tipo de accidente e impacto. Se concluye que las condiciones locales, tipos de accidente e impacto se destacan entre las múltiples dimensiones que envuelven la gravedad de las ocurrencias con motociclistas.Os objetivos deste estudo foram caracterizar as ocorrências de trânsito com motocicleta, segundo condições locais, dados relacionados ao tipo de acidente, data e hora, além de identificar, entre essas variáveis, aquelas que se associaram à morte das vítimas. Como método foi usado o estudo retrospectivo, utilizando dados dos Boletins de Ocorrência de Trânsito, referentes ao ano 2004, e os registros de óbito do Instituto Médico Legal. Tem-se como resultados que 99,4% das ocorrências aconteceram em área urbana, em locais onde as condições de luminosidade (87,4%), condição meteorológica (80,6%) e sinalização (70,6%) eram satisfatórias. Predominou a colisão de motocicleta com carro ou caminhonete (55,5%) e as quedas de motocicleta foram a seguir as mais frequentes (18,0%). No tipo de impacto, o maior percentual foi observado na categoria abalroamento transversal (35,2%). O grupo de mortos diferiu em relação aos sobreviventes quanto à área e luminosidade do local da ocorrência, além do tipo de acidente e impacto. Conclui-se que as condições locais, tipos de acidente e impacto destacam-se entre as múltiplas dimensões que envolvem a gravidade das ocorrências com motociclistas

Once-in-a-lifetime leisure experiences (OLLE): the role of flow, novelty, and interpersonal interaction on tourists’ satisfaction and memories

Drawing on Flow theory and memorable tourism experience, this study explores the relationships between Flow, novelty, and interpersonal interaction and the impact on travelers' satisfaction and memories. By applying a mixed-method approach and the critical incident technique to a once-in-a-lifetime leisure experience, 550 tourists recalled their experiences. The results reveal that Flow has a direct and positive influence on tourists' satisfaction and memories of the experience. The findings highlight the role of novelty and interpersonal interaction in producing positive Flow. However, novelty and interpersonal interaction did not come out as significant to predict memories and satisfaction.info:eu-repo/semantics/publishedVersio

Orbital floor reconstruction with high density polyethylene

Surgical interventions in blow out fractures are generally indicated in cases of alterations in orbital function (e.g. diplopia)and for aesthetic reasons (e.g. enophthalmos). In assessing the severity of the injury, the clinician often uses parameterssuch as changes in visual acuity, patient-reported diplopia, changes in globe position and evaluation of the extraocularmuscles in association with imaging exams. Computed tomography has been the modality of choice for detailed imagingdiagnosis and surgical planning of orbital trauma. High density polyethylene may be successfully used in orbital floorreconstruction to restore function and esthetics. Taking into account the follow up of six months, the availability and theadvantages of high density polyethylene implants, it can be concluded that their use in reconstruction of orbital floordefects is a good choice
