Progress in ultrafast science and technology has pushed the temporal resolution to subfemtosecond and attosecond region (Kienberger el at., 2002; Fleischer & Moiseyev, 2006; Corkum & Krausz, 2007; Goulielmakis el at., 2007) and technology exploration in ultrashort pulse generation has made it possible to equip femtosecond lasers that are only a few cycles in duration (Xu el at., 1996; Shirakawa...

The objective of this study is to quantify the nature of the mechanisms of southern Africa rainfall variability, unrelated to the El Nino Southern Oscillation, by means of a simple empirical composite analysis, as a baseline for a more detailed study.

In a recent Editorial for this journal, El-Jardali and Fadlallah proposed a new framework for Knowledge Translation (KT) in healthcare. Many such frameworks already exist; thus, new entrants to the field must be scrutinized in regard to their unique contributions to advancing understanding and practice. The El-Jardali and Fadlallah framework focuses on policy-level discussions, a relatively und...

Three different classes of numerical models successfully predicted the occurrence of the El Niño of 1986-87 at lead times of 3 to 9 months. Although the magnitude and timing of predicted ocean surface temperatures were not perfect, these results suggest that routine prediction of moderate to lare El Niño events is feasible. The key to the success of the models lies in recognizing or simulating ...

Endothelial lipase (EL) is a determinant of high density lipoprotein-cholesterol (HDL-C) level, which is negatively correlated with atherosclerosis susceptibility. We found no difference in aortic atherosclerotic lesion areas between 26-week-old EL+/+ apolipoprotein E-deficient (apoE-/-) and EL-/- apoE-/- mice. To more firmly establish the role of EL in atherosclerosis, we extended our study to...

Enterolactone (EL) is an enterolignan found in human subjects. In this pilot study, the enantiomeric ratios of serum EL were determined in serum from healthy adults during consumption of habitual diet, and after an 8-day supplementation with flaxseed (25 g/day). (-)EL dominated in all serum samples collected during habitual diet consumption. However, the ratio of (-)EL and (+)EL enantiomers dif...

El problema a resolver es mantener siempre en posición vertical la masa junto con la varilla, tratando de mover el carro para lograrlo. El péndulo esta sostenido por una chumacera, encima de un carro que a su vez tiene movimiento por medio de un sistema de deslizamiento dinámico, por lo cual éste puede adoptar dos tipos de direcciones sobre el plano x, y que afecta directamente con el ángulo te...

Título: Uso de la tecnología de comunicación para el trabajo en casa durante el tiempo fuera del trabajo y el conflicto trabajo-familia: los roles del apoyo familiar y el desapego psicológico. Resumen: Este estudio analiza la influencia del uso de las tecnologías de la comunicación para el trabajo en casa durante el tiempo fuera del trabajo en el conflicto trabajo-familia. Nuestro análisis se b...
