Abstract: A fill sheet and a fill pack manufactured from a plurality of fill sheets for cooling a cooling medium in a cooling tower, each fill sheet having a plurality of flutes extending diagonally from top to bottom of the fill sheet, the diagonal orientation of the flutes resulting from a plurality of alternating longer diagonal flute segments and shorter vertical flute segments, each of the plurality of flutes having the microstructure comprising a plurality of alternating rounded mounds and rounded depressions extending between flat ridge edges and flat valley edges of said flutes.

Abstract: Compounds that modulate the oxidoreductase enzyme indoleamine 2,3-dioxygenase, and compositions containing the compounds, are described herein. The use of such compounds and compositions for the treatment and/or prevention of a diverse array of diseases, disorders and conditions, including cancer- and immune-related disorders, that are mediated by indoleamine 2,3-dioxygenase is also provided.

Abstract: A new heat exchange tube fin design in which a plurality of arrowhead shapes are pressed into or embossed onto each fin, the arrowhead shape defined by two intersecting wedge sections. The pressed arrowhead shapes are grouped into nested pairs, and one of the arrowheads in a pair is pressed as a positive relative to the fin plane and the other of the pair is pressed as a negative relative to the fin plane. The arrowhead pairs are placed in rows parallel to the air flow direction and arrowhead pairs in one row are preferably staggered relative to the arrowhead pairs in the adjacent row along the fin in the air flow direction.
