Bacterial Cellulose biosynthesis is one of the most important applied biochemical processes in biology. In order to explain the detailed molecular events of bacterial cellulose biosynthesis, we discuss in this work, the different steps required for bacterial cellulose formation and crystallization from sugar cane and honey. The potential of organisms to produce biocellulose fibers was analyzed....

OBJECTIVES To assess the incidence of injuries to young children sustained by contact with a domestic vacuum cleaner and to highlight the potential for significant injury. An increase in public awareness of these risks might result in a reduction in morbidity. METHODS Over a period of one year, all children attending with an injury sustained because of contact with a domestic vacuum cleaner h...

Kinetic models are the most important tools for the prediction and evaluation of the flotation circuits performance. In order to determine the kinetic order and rate of flotation of a Gilsonite sample, flotation experiments were conducted using the combination of Gasoline-Pine Oil, and one test without any collector and frother. The pulp density was 10% and the experiments were carried out in b...

Interactions between pelagic thresher sharks (Alopias pelagicus) and cleaner wrasse were investigated at a seamount in the Philippines. Cleaning associations between sharks and teleosts are poorly understood, but the observable interactions seen at this site may explain why these mainly oceanic sharks regularly venture into shallow coastal waters where they are vulnerable to disturbance from hu...
