Abstract: A wood-derived carbohydrate composition is disclosed. The wood-derived carbohydrate composition comprises monomeric C6 sugars and monomeric C5 in a total amount of at least 94 weight-% based on the total dry matter content of the carbohydrate composition, wherein the weight ratio of the monomeric C5 sugars to the monomeric C6 sugars is at most 0.1. Disclosed is also a method for producing a wood-derived carbohydrate composition.

Abstract: A process for polymerizing olefin monomer(s) in a gas-solids olefin polymerization reactor comprising a top zone; a middle zone, which comprises a top end in direct contact with said top zone and which is located below said top zone, the middle zone having a generally cylindrical shape; and a bottom zone, which is in direct contact with a bottom end of the middle zone and which is located below the middle zone; comprising the following steps: introducing a fluidization gas stream into the bottom zone; polymerizing olefin monomer(s) in the presence of a polymerization catalyst in a dense phase formed by particles of a polymer of the olefin monomer(s) suspended in an upwards flowing stream of the fluidization gas in the middle zone; introducing a jet gas stream through one or more jet gas feeding ports in a jet gas feeding area of the middle zone at the dense phase in the middle zone of the gas-solids olefin polymerization reactor; wherein the kinetic energy (EJG) input in the reactor by the jet stream is betwe

Abstract: In a display (202) comprised in an elevator system, more than one floor symbol (205) but less than all the floor symbols corresponding to different floors in the elevator system are highlighted at a time. At least the floor symbol corresponding to the current position and that corresponding to the next floor in the travelling direction is highlighted. The display is preferably so controlled that it scrolls the floor symbols (205) with respect to the car symbol (203). When the elevator car is at a given floor, the floor symbol corresponding to such floor coincides with the car symbol, and when the elevator car moves away from the floor, the floor symbol ceases to coincide with that car symbol, and as the car comes to the next floor, the corresponding floor symbol coincides with that car symbol.
