Yogurt consumption is associated with a better lifestyle in Brazilian population.

Background: The importance of dairy products is recognized for their health benefits. However, additional investigation is required to understand the characteristics of the lifestyle of people who incorporate yogurt into their eating routine. Then, the aim of this study was to compare the lifestyle of yogurt consumers and non-consumers.

Diel oscillation in the optical activity of carotenoids in the absorption spectrum of Nannochloropsis.

In this paper we show that the absorption spectrum of the microalgae Nannochloropsis oceanica exhibits changes in response to the modulation of incident light. A model was used to analyze the contribution of different active pigments to the total absorption in the photosynthetically active radiation region and suggested consistent diel oscillations in the optical activity of carotenoids.

Stability Diagrams for Paul Ion Traps Driven by Two-Frequencies.

In this paper, we present and discuss stability diagrams for Paul traps driven by two ac voltages. In contrast to a typical Paul trap, here we suggest a secondary ac voltage whose frequency is twice the frequency of the primary one. The ratio between their amplitudes can be used to expand the region of stability and to access different states of motion of trapped ions.

Probability and amounts of yogurt intake are differently affected by sociodemographic, economic, and lifestyle factors in adults and the elderly-results from a population-based study.

The aim of this population-based cross-sectional health survey (N = 532) was to investigate the factors associated with the probability and amounts of yogurt intake in Brazilian adults and the elderly. A structured questionnaire was used to obtain data on demographics, socioeconomic information, presence of morbidities and lifestyle and anthropometric characteristics. Food intake was evaluated using two nonconsecutive 24-hour dietary recalls and a Food Frequency Questionnaire.
