Abstract: The invention relates to methods of manufacturing nano pulp, wherein cellulose containing raw material is accelerated in a continuous gas and/or liquid flow, whereby the material is disintegrated and nano pulp is produced. The gas and/or liquid flow may be created by reduction of an elevated pressure in a reactor holding the cellulose containing raw material. The invention also relates to the nano pulp produced.

Abstract: Alert conditions datasets are created from historic data taken from actual incidents for which the alert condition datasets are to indicate during future operations. A networked computers system including various devices is monitored for alert conditions associated with one, or more, of the devices. The severity of an alert is based on the number of alert conditions met for a given alert conditions dataset.

Abstract: A sandwich material includes at least 3 layers: a first cover layer, an intermediate layer, and a second cover layer. The intermediate layer is in the form of at least one segmented sheet and includes a mixture of polymer and cellulose fibers. The sheet may include susceptors. Several processes can be used for manufacturing the sandwich material.

Abstract: A method for regeneration of a cellulose containing material, comprises the steps: a) exposing the cellulose containing material to oxygen with an alkali aqueous solution at a pH of at least 9, and a temperature of at least 20° C., b) dispersing the cellulose containing material in the alkali aqueous solution, wherein the temperature of the alkali aqueous solution is lowered below 15° C., and wherein the pH of the alkali aqueous solution is above 9, c) adding an organic solvent to the dispersion to precipitate cellulose, and d) separating the precipitated cellulose by at least one method selected from filtering and centrifugation. The method makes it possible to maintain a high alkali pH value in the process, which saves costs since the pH value does not have to be lowered by additions of various additives. The method makes it possible to remove non-cellulose parts of the cloth.

Abstract: The method is for the preparation of kraft pulp with increased pulping yield from lignin-containing cellulosic material using polysulfide cooking liquor. In order to increase carbohydrate stabilization and hence the yield from a kraft cooking process a first impregnation stage is using polysulfide cooking liquor implemented at high alkali and polysulfide concentration and at a low temperature.

Abstract: The continuous digester system has an inlet defined therein for the feed of a chips suspension and an outlet for the output of a cooked suspension of pulp. The suspension of chips is fed in to the inlet through a line at the beginning of the cook, where the chips suspension has a volume of starting cooking fluid that establishes a fluid/wood ratio that is greater than 3.5. A final cooking fluid is present during the cook for the major part of the cock and is withdrawn through a withdrawal strainer only during the final 15 minutes of the cook. The final cooking fluid ensures a fluid/wood ratio that is greater than 3.5 in association with the withdrawal. The withdrawn final cooking fluid during the final 15 minutes of the cook consists of spent black liquor that maintains a residual alkali level that lies under 15 g/l.

Abstract: A system and method of selectively restricting usage of a user equipment (UE) in a telecommunications system. The system includes a graphical user interface (GUI) for receiving a plurality of restrictions. Each restriction provides a constraint on use of the UE. The GUI allows an administrator of the UE to select and modify the restrictions. The system also includes a traffic server for determining if usage of the UE is within one of the restrictions. If the UE is within one of the restrictions, the traffic server terminates the call. The restrictions may include a time of the day, day of the week or geographical location.
