Chemical communication in Apis mellifera: Temporal modulation of alarm behaviors
(1996-01-01)
The effect of pheromones and their chemical analogues in honeybee alarm behaviors was studied in observation boxes. Defensive behaviors, as follows: a) attraction to scent source, b) elevation of wings in 'V', c) abdomen ...

Short communication: Mycosporine-like amino acids protect natamycin against photodegradation in milk exposed to fluorescent or light-emitting diode light
(2019-06-01)
Natamycin has been used as a natural antimicrobial in dairy products, but the poor light stability of natamycin can limit usefulness in food products. Mycosporine-like amino acids are strong UV absorbers and might be useful ...
The influence of acetic acid on the ethanol electrooxidation on a platinum electrode
(ELSEVIER SCIENCE INC, 2011)

Trifluoromethanesulfonic acid supported on carbon used as catalysts in the synthesis of flavones and chromones
(Elsevier Science, 2009-01)
Solid acid catalysts based on trifluoromethanesulfonic acid (TFMS) were synthesized using two different activated carbons as supports. They were characterized by FT-IR, DTA-TGA and BET, and their acidity was measured by ...
