Bioavailability and pharmacokinetics of (poly)phenols following consumption of selected blueberries and a blueberry-rich protein bar by adult males and females: a randomized, crossover, controlled trial.

Background: It is commonly believed that higher nutrient content equates to healthier foods and that food processing lowers nutrient content, although bioavailability studies often indicate otherwise. Blueberries, a rich source of (poly)phenols with proven health benefits, provide a feasible model to evaluate phytochemical bioavailability following consumption of raw and processed fruits.

Objectives: This study evaluates the effect of processing on the bioavailability of (poly)phenols following consumption of 4 interventions: 2 blueberry varieties (i.

Experimental study of geysers through a vent pipe connected to flowing sewers.

Geysers of air-water mixtures in urban drainage systems is receiving considerable attention due to public safety concerns. However, the geyser formation process and its relation with air release from pressurized pipes are still relatively little known. A large-scale physical model, that consisted of a main tunnel with a diameter of 270 mm and a length of 25 m connecting two reservoirs and a vertical vent pipe, was established to investigate geyser evolution and pressure transients.

[Inactive dumps in Santa Catarina's carboniferous area: analysis of risks to the public health and the environment].

The existence of inactive dumps considerably increases the so-called "environmental liability"; so much so that the final destination of urban solid residues takes a prominent place on the list of environmental issues of societies(1). In the state of Santa Catarina, it can be said that, currently, the real conditions of the "final destination deposits", or simply the inactive dumps, is officially unknown. This is maybe most evident in the carboniferous area of the state that already suffers from the environmental impact of coal mining.
