Abstract: We show that it is possible to decrease the energy load of tribojoints of band-block brakes of drawworks with the help of additional metal–semiconductor and polymer–semiconductor friction couples obtained by introducing cylindrical inserts made of… read more here.

DOI: 10.3390/life12122121
Abstract: Unlike most animals, most bats cannot synthesize vitamin C endogenously. Consequently, this vitamin must be obtained from the diet. Among the bat species, there are several food groups, such as frugivorous, nectarivorous, insectivorous, and hematophagous.… read more here.
