Tetragonisca angustula flora availability. "T. angustula" honey contains more moisture than honey from typical honey bees and is also more acidic, giving it a complex flavor. Honey and propolis, a glue like substance that bees use as sealant, collected by "T. angustula" have some health benefits for humans. The honey and propolis contain various chemicals that show antibacterial activity towards an infection causing bacteria, "Staphylococcus aureus". Honey and propolis gathered from different geographical areas have different chemical compositions yet they all exhibit some type of antibacterial activity. Another bee, "Apis mellifera", produces honey and propolis with very similar qualities. Forests are being
Wood glue normal wood bending can break the bond in some applications. Often, too much adhesive is applied which leads to a much weaker bond. CA has quickly become the dominant adhesive used by builders of balsa wood models, where its strength far exceeds the base materials. Casein glue was used to make strong and robust joints in early aviation, but fell out of favor due to its susceptibility to attack by bacteria. Polyvinyl acetate (PVA), also known as "white glue" or "hobby and craft", is non-toxic and very easy to use, but hard to repair since most glues (including PVA itself)
