OBJECTIVES Propylene glycol (PG) (1-2 propanediol; CAS No 57-55-6) is a low toxicity compound widely used as a food additive, in pharmaceutical preparations, in cosmetics, and in the workplace-for example, water based paints, de-icing fluids, and cooling liquids. Exposure to PG mist may occur from smoke generators in discotheques, theatres, and aviation emergency training. Propylene glycol may ...

Efficient and unbiased sampling of ecological interactions is essential to our understanding the functions they mediate. Seed dispersal by frugivorous birds a key mutualism for plant regeneration community dynamics. Mist‐netting one most widely used methods sample avian seed through identification seeds in droppings captured kept inside cloth bags. However, may drop on ground before being extra...

The fracture behaviour of a specific material, semi-crystalline biobased polymer, was here studied. Dynamic tests on strip band specimens were carried out. Fracture surfaces observed at different scales by optical and electron microscopy to describe cracking scenarios. Crack initiation, propagation arrest zones described. Three distinct are highlighted in the initiation zone: zone with conical ...

Film cooling is a cooling technique widely used in highperformance gas turbines to protect the turbine airfoils from being damaged by hot flue gases. Motivated by the need to further improve film cooling in terms of both cooling effectiveness and coolant coverage area, the mist/air film cooling scheme is investigated through experiments in this study. A small amount of tiny water droplets (7% w...

ed. But, to be honest, the genes that underlie Heliconius wing patterns still seem like a rainforest under a shroud of fog. Only a few canopy trees are visible as we fly over. It should be exciting when the

One hundred twelve crossbred feedlot heifers were used in two experiments to assess the impact of heat stress and its relief by shade and(or) water misting on behavior, physiology, performance, and carcass traits. Treatments were 1) no shading or misting (CONT); 2) only misting (MIST); 3) only shading (SHADE); and 4) shading plus misting (SHMI). Head in the feed bunk, head in or above the water...
