    Abstract: The present invention relates to a process for the controlling the sodium and sulfur levels in a pulp mill, comprising the steps of: a) providing a pulp mill stream comprising sulfide and having a total alkali concentration of at least 2 Molar; b) supplying a portion of the pulp mill stream to a reactor comprising sulfide oxidizing bacteria and removing sulfide from the pulp mill stream by subjecting said stream to sulfide oxidizing bacteria in the presence of oxygen, and at a pH in the range 8 to 11, to oxidize the sulfide to elemental sulfur, c) withdrawing from the reactor a treated pulp mill stream comprising sulfur, wherein the portion of the pulp mill stream is mixed with a portion of the sulfide oxidizing bacteria present in the reactor prior to supplying the pulp mill stream to the reactor in step b).

    Abstract: A method (200, 300, 500) for producing an electrically conductive pattern on substrate (202, 402), comprising: providing electrically conductive solid particles onto an area of the substrate in a predefined pattern (508), where the pattern (403) comprises a contact area (404B) for connecting to an electronic component and a conductive structure (404A) having at least a portion (414) adjacent to the contact area, heating the conductive particles to a temperature higher than a characteristic melting point of the particles to establish a melt (510), and pressing the melt against the substrate in a nip, the temperature of the contact portion of which being lower than the aforesaid characteristic melting point so as to solidify the particles into essentially electrically continuous layer within the contact area and within the conductive structure in accordance with the pattern (512), wherein the thermal masses of the contact area and the at least adjacent portion of the conductive structure are configured substantially equal.
