The literature widely recognizes that shift workers have more health complaints than the general population. The objective of this study was to describe the prevalence of sleep complaints and verify the polysomnographic ...

This paper introduces the concept of common deterministic shifts (CDS). This concept is simple, intuitive and relates to the common structure of shifts or policy interventions. We propose a Reduced Rank technique to ...

The 13C chemical shifts of 15 pentacyclic terpenoids (fernenes) are compared to predicted 13C NMR chemical shifts obtained via empirically scaled GIAO shieldings. We report that accurate (rms error approx. 1.5 ppm) predictions ...

The sustainability of shifting cultivation is presently a topic of debate in scientific and institutional communities; however, there is no current consensus. To address this debate, we performed a search of the pertinent ...

Neste estudo, avaliamos empiricamente a ocorrência de comportamento de risk-shifting. Conduzimos o estudo usando uma abordagem diff-in-diff com várias especificações em um ambiente de experimento natural devido a dois ...

This work describes the process of nanofabrication of phase-shifted Bragg gratings on the end facet of a multimode optical fiber with a pulsed DC sputtering system based on a single target. Several structures have been ...

Objective: The objective of this study was to analyze the effect of individual circadian preferences of drivers with fixed night work schedules on sleep patterns. Subjects and Methods: A total of 123 professional drivers, ...
