Bem-estar subjetivo: em busca da qualidade de vida

Abstract: The subjective well-being is a growing interest in the area of Psychology. This interest is shown in studies under different titles and key words: happiness, satisfaction, and positive affect, besides the subjective evaluation of quality of life. Subjective well being is concerned with what people think and feel about their lives. The distinct perspectives on the matter have defined subjective well-being as a wide category of a phenomenon that includes emotional responses, satisfaction domains, and the global judgments of life’s satisfactions. The present study introduces this new area of Psychology, its conceptual and evaluative aspects, as well as its main contributions to comprehend the life events impact on quality of life.

Acerola nectar with added microencapsulated probiotic

Abstract: The aim of this study was to evaluate the survival of a probiotic microorganism microencapsulated in cellulose acetate phthalate, added to acerola nectar. The changes in pH, Brix, organic acid content and color of the product during its shelf-life were evaluated. A total of 3 processing runs were carried out on a semi-industrial scale, each consisting of a 15-liter batch of acerola nectar with added prebiotics and a microencapsulated probiotic culture. The physicochemical characteristics of the samples remained stable throughout storage. After 30 days storage the acerola nectar samples containing microencapsulated probiotic microorganisms exhibited counts above 8 log CFU per 200 mL, within the limits set by the Brazilian regulation for functional foods. On the other hand, the samples containing free Bifidobacterium animalis cells showed counts of 5.9 log CFU per 200 mL after the same storage time. It was concluded that microencapsulation was a suitable technique for improving the viability of probiotic microorganisms in acerola nectar during cold storage.

LLAMA: normal star formation efficiencies of molecular gas in the centres of luminous Seyfert galaxies

Abstract: Using new Atacama Pathfinder Experiment and James Clerk Maxwell Telescope spectroscopy of the CO 2→1 line, we undertake a controlled study of cold molecular gas in moderately luminous (Lbol = 1043–44.5 erg s−1) active galactic nuclei (AGN) and inactive galaxies from the Luminous Local AGN with Matched Analogs (LLAMA) survey. We use spatially resolved infrared photometry of the LLAMA galaxies from 2MASS, the Wide-field Infrared Survey Explorer the Infrared Astronomical Satellite and the Herschel Space Observatory (Herschel), corrected for nuclear emission using multicomponent spectral energy distribution fits, to examine the dust-reprocessed star formation rates, molecular gas fractions and star formation efficiencies (SFEs) over their central 1–3 kpc. We find that the gas fractions and central SFEs of both active and inactive galaxies are similar when controlling for host stellar mass and morphology (Hubble type). The equivalent central molecular gas depletion times are consistent with the discs of normal spiral galaxies in the local Universe. Despite energetic arguments that the AGN in LLAMA should be capable of disrupting the observable cold molecular gas in their central environments, our results indicate that nuclear radiation only couples weakly with this phase. We find a mild preference for obscured AGN to contain higher amounts of central molecular gas, which suggests connection between AGN obscuration and the gaseous environment of the nucleus. Systems with depressed SFEs are not found among the LLAMA AGN. We speculate that the processes that sustain the collapse of molecular gas into dense pre-stellar cores may also be a prerequisite for the inflow of material on to AGN accretion discs.
