Compounds of formula (I), or salts thereof, which inhibit acetyl CoA(acetyl coenzyme A):diacylglycerol acyltransferase (DGAT1) activity are provided, wherein, for example, R1 is an optionally substituted aryl or optionally substituted heteroaryl group, Y is a direct bond, or a defined linking group and R2 is an optionally substituted aryl, an optionally substituted cycloalkyl or an optionally substituted heterocyclic group; together with processes for their preparation, pharmaceutical compositions containing them and their use as medicaments.
摘要:
An aircraft comprises a wing tip device, for example a winglet, a raked-tip device, a wing tip fence or a planar wing extension, mounted in the region of the tip of a wing on the aircraft. The wing tip device is rotatably moveable between a first position and a second position, in which the upward lift produced by the wing or the wing tip device is reduced. During flight, the bending moment at the root of the aircraft wing therefore changes in dependence on the position of the wing tip device. The maximum bending moment in the aircraft wing sustained during high-load conditions is thereby reduced, allowing the structural mass of the aircraft to be reduced.
摘要:
A hand guard assembly for a firearm including a barrel. The assembly includes a tubular unitary body mounted to surround a portion of the barrel substantially coaxially and in a transversely spaced relationship. The tubular body includes a plurality of air flow openings formed therethrough and at least one of a top rail formed as a unitary portion of the tubular body and extending rearwardly along an upper portion of a receiver of the firearm, side accessory rails formed as a unitary portion of the tubular body and on opposed sides of the tubular body, and a bottom accessory rail formed as a unitary portion of the tubular body and on a bottom surface of the tubular body. In the preferred method of fabricating the assembly, the body and any include accessory rails are extruded.

摘要:
The invention relates to a group of novel indole compounds of Formula (I): wherein: R1, R2, R4, R6, R6a, R7, R8, R9, R10, and A are as defined in the specification, which are useful as gonadotrophin releasing hormone antagonists. The invention also relates to pharmaceutical formulations of said compounds, methods of treatment using said compounds and to processes for the preparation of said compounds.
摘要:
An integrated circuit (10) includes a semiconductor substrate (11) that has a top surface (32) for forming a dielectric region (14) with a trench (40) and one or more adjacent cavities (16). A conductive material such as copper is disposed within the trench to produce an inductor (50). A top surface (49) of the inductor is substantially coplanar with an interconnect surface (31) of the semiconductor substrate, which facilitates connecting to the inductor with standard integrated circuit metallization (57).
摘要:
A system for communicating data comprising a client station adapted to connect to a server station by a wireless contention link for exchanging data between the client station and the server station, where the data exchanged has loose quality of service requirements. The client station is also adapted to connect to the server station by at least one wireless non-contenition link for transmitting data from the server station to the client station where the data transmitted has stringent quality of service requirements.
