Abstract: A method and equipment for distribution of two fluids into and out of channels in a multi-channel monolithic structure (monolith) where the channel openings are spread over an entire cross-sectional area of the monolithic structure. The equipment consists of a manifold head, a monolith unit or a monolith stack, a row of monolith units or monolith stacks, or a monolith block. In addition a method and a reactor for mass and/or heat transfer between two fluids transfers the two fluids using one or more of the manifold heads and monolith units, the monolith stack, the row of monolith units or monolith stacks, or the monolith block.

Abstract: A method of collecting secretions from trees including making a predetermined shaped incision through the bark to the surface of the wood and applying a secretion flow activation agent to the incision. The method further includes placing a receptacle in the incision, wherein the receptacle comprises a lower outer part and a flow tube portion located at the lower outer part, and wherein a portion of the receptacle has the same shape as the predetermined shape of the incision. The method further includes fixing a collecting apparatus to the flow tube and subsequently removing the collecting apparatus from the flow tube when the collecting apparatus contains secretions from the trees.
