This study focuses on the implications of urban life style on eating habits and the related symbolic representations. Theoretical references used to approach the food experience are the concepts of social representation and habitus. The methodology consisted of a qualitative analysis of interviews with 21 administrative employees and field observations made at commercial establishments in downt...

Subject of research: technology for the production gluten-free cereal bars

 Main scientific results: Changes amino acid composition sorghum grain due to microwave processing were determined. Formulations develo...

Organic brown rice syrup (OBRS) is a sweetener frequently used as an alternative to high-fructose corn syrup in organic and health food products. In a study of children’s foods, a team of researchers discovered high levels of arsenic in toddler formula products that contained OBRS. Given evidence that arsenic accumulates in rice at high levels, the researchers suspected OBRS was the source of t...

Caenorhabditis elegans has been shown to measure variability in environmental food density, using the information to fine-tune foraging strategies; a compact neural circuit has been identified that responds to large fluctuations in food-related cues and uses dopamine to encode the amount of recently encountered variability.

I present a brief review of what is known about double-barred galaxies, where a small (“inner”) bar is nested inside a larger (“outer”) bar; the review is focused primarily on their demographics and photometric properties. Roughly 20% of S0–Sb galaxies are doublebarred; they may be rarer in later Hubble types. Inner bars are typically ∼500 pc in radius (∼12% the size of outer bars), but sizes r...

In this paper the capability of Gurson-Tvergaard-Needleman (GTN) model in the prediction of ductile damage in 7075-T651 aluminum alloy is investigated. For this purpose, three types of specimens were tested: Standard tensile bars, Round notched bar (RNB) specimens and compact tension (C(T)) specimens. Standard tensile bar tests were used to obtain the mechanical properties of the material and t...

A substantial fraction of barred galaxies host additional nuclear bars which tumble with pattern speeds exceeding those of the large-scale (primary) stellar bars. We have investigated the mechanism of formation and dynamical decoupling in such nested bars which include gaseous (secondary) nuclear bars within the full size galactic disks, hosting a double inner Lindblad resonance. Becoming incre...

The central kpc of barred galaxies exhibits a wealth of morphological information on different components with clear dynamical consequences. These include nuclear rings, spirals, bars, and more. We argue that this morphology is driven by large-scale stellar bars and analyze its consequences for gas dynamics and the distribution of star-forming regions. Specifically, we focus on gas flows in nes...

BACKGROUND Changes to school food environments and practices that lead to improved dietary behavior are a powerful strategy to reverse the childhood obesity epidemic. OBJECTIVES To estimate the effects of school food environments and practices, characterized by access to competitive foods and beverages, school lunches, and nutrition promotion, on children's consumption of sugar-sweetened beve...

Error bars commonly appear in figures in publications, but experimental biologists are often unsure how they should be used and interpreted. In this article we illustrate some basic features of error bars and explain how they can help communicate data and assist correct interpretation. Error bars may show confidence intervals, standard errors, standard deviations, or other quantities. Different...
