摘要:
A method for transporting in a microfluidic conduit an aliquot of a liquid, possibly containing a substance I, which is dissolved in the liquid and typically exhibits charged groups and/or hydrophobic groups. The method is characterized in that the liquid contains an amphiphilic macromolecular substance.

This invention relates to a new and improved way of continuously cooking fiber material, wherein temperatures and alkaline levels are controlled to be maintained within specific levels in different zones of the digesting process in order to optimize chemical consumption and heat-economy and at the same time achieve very good pulp properties.
摘要:
The present invention provides a method for continuously cooking kraft pulp in a digester having the steps of:feeding chips into an inlet of a digester;supplying black liquor to an impregnation zone of the digester in an amount such that the black liquor makes up greater than 40% by volume of the total volume of liquid present in the impregnation zone;extracting liquor from a screen girdle downstream of where the black liquor is added to the digester, in the direction the wood chips flow through the digester, in an amount greater than 50% by volume of the total volume of liquor present at the location of the screen girdle;maintaining a liquor:wood ratio in the impregnation zone of greater than 3:1; anddischarging cooked pulp from the digester.
摘要:
A microfluidic device that comprises a microchannel structure in which there are one, two or more flow paths (101;201a,b;301a,a′,b) all of which comprises a porous bed I (104,204,304) that is common for all of the flow paths and exposes an immobilized reactant R that is capable of interacting with a solute S that passes through the bed. The characteristics are that at least one of the flow paths comprises/comprise a second porous bed II (105,205,305) that is placed upstream of porous bed I (104,204,304) and is dummy with respect to interaction with solute S but capable of interacting with a substance DS that is present in a liquid aliquot together with solute S and is capable of disturbing the result of the interaction between solute S and said immobilized reactant R. There is also disclosed a method utilizing the device and variant of the device in which the immobilized R is replaced with a generic affinity ligand LI and/or porous bed II exposes a generic ligand LII that may be different from LI.
摘要:
A microfluidic device comprising one, two, three or more enclosed microchannel structures, each of which comprises a) an inlet arrangement with an inlet opening for liquid, b)a reaction microcavity (RM1) downstream to the inlet opening, and c) an upstream section that is located between the inlet opening and the reaction microcavity (RM1) and is defined between two planar substrates made of plastic material which substrates are common for said microchannel structures. The characteristic feature is that the inner wall in said upstream section exposes a hydrophilic surface area with an underlying base layer comprising metal oxide. In one aspect the microfluidic device as such is covered.

A method for characterizing n components An of n catalytic systems. The method is characterized in comprising the steps of: I) providing a microfluidic device which comprises a plurality of identical microchannel structures, each microchannel structures comprising in the downstream direction (a) an inlet arrangement IA with at least one inlet port; (b) a catalytic microcavity MC1, which comprises an immobilized component Cim of the catalytic system CS used in the microchannel structure, and (c) a detection zone (DZ); ii) distributing to MC1 of each microchannel structure the remaining components of the CS used in the structure by a) dispensing to the inlet arrangement IA of each microchannel structure said remaining components; and b) transporting corresponding components for the microchannel structures in parallel to load MC1 in each microchannel structure; iii) performing the catalytic reaction in MC1 of each microchannel structure; iv) transporting in parallel the product formed in step (iii) from MC1 to DZ of each microchannel structure, if DZ and MC1 do not coincide; v) characterizing for each microchannel structure the result of the catalytic reaction performed in MC1 in DZ; and vi) characterizing An for each microchannel structure.
摘要:
A method to cook thin chips in a continuous digester vessel including: introducing thin chips having a thickness of no more than 6 mm, into a chip bin; adding white (cooking) liquor to the chip bin or to a chip transport passage extending from the chip bin to an upper inlet of the continuous digester vessel; injecting medium pressure steam or another heated fluid to an upper region of the digester vessel to elevate a cooking temperature of the chips in the vessel to at least 130 degrees Celsius; cooking the chips in the vessel as the chips flow downward through the vessel without substantial extraction or introduction of liquor in the cooking section of the vessel; injecting wash liquid to a lower region of the vessel; extracting at least wash liquid through a wash liquid extraction screen in the lower region of the vessel and above the injection of the wash liquid, and discharging the cooked thin chips from the lower region of the vessel.
摘要:
A method and system for at least one of communication and interaction between a vehicle driver and a plurality of at least one of integrated and non-integrated applications like, e.g., native vehicle applications and/or aftermarket applications and/or nomad applications is disclosed. Especially, such a method and system for managing the at least one of communication and interaction by means of an interaction manager is provided, by which this at least one of communication and interaction is conducted or managed in such a way that risks and impairments for the safety and comfort of the driver are reduced considerably and workload and distraction of the driver are reduced considerably as well.
