Abstract: Processes are provided herein for the preparation of a bicyclic ketone compound of formula (I), or a stereoisomer thereof: or a pharmaceutically acceptable salt thereof, wherein R1, R2, R3 and n are as defined herein; and compounds prepared by these processes.

Abstract: The present disclosure describes an apparatus of measuring light scattering of a sample. In an embodiment, the apparatus includes (1) at least one display logically coupled to an enclosure housing a light scattering measurement instrument, where the at least one display is configured to allow for operating the instrument to acquire light scattering data from the sample and for accessing the data, (2) an indicator connected to an outside surface of the enclosure, where the indicator is configured to indicate at least one status of the instrument, (3) a sample chamber configured to accommodate at least one sample cell, where each of the at least one sample cell has a unique size and a unique shape, and (4) and a sample door connected to the enclosure, where the sample door is configured to seal the sample chamber, thereby providing thermal insulation to the sample chamber.

Abstract: An optical apparatus for photographic or videographic uses may include an optical lens configured to affect light passing therethrough. The optical apparatus may also include a handle mechanism attached to the filter and configured to be held by a user to position the filter in front of a camera lens.

Abstract: A surfactant composition comprising: (a) a surfactant material; (c) a polyethylene imine of the general formula —(CH2CH2NH)n—; and (d) an aromatic, monoethylenically-unsaturated carboxylic acid ester of the formula where R1 is selected from the group consisting of hydrogen, C1-C16 alkyl, C1-C16 alkoxy, aryl and substituted aryl, and R2 is selected from the group consisting of aryl, substituted aryl and C6-C16 alkyl; the materials (b)-(d) each having an odour value of 10,000 maximum. The problem of rancidity, commonly encountered when low-grade surfactant materials are used, especially in soaps, is considerably reduced.
