The invention relates to novel designer osteogenic proteins having altered affinity for a cognate receptor, nucleic acids encoding the same, and methods of use therefor. More preferably, the novel designer osteogenic proteins are designer BMPs and have altered affinity for a cognate BMP receptor. The designer BMPs demonstrate altered biological characteristics and provide potential useful novel therapeutics.

A display positioning apparatus is provided for lifting, supporting, and/or positioning a load, such as a display. The apparatus includes a base and a lift arm adapted to couple to a display, the lift arm pivotally coupled to the base providing a range of travel. A balance mechanism is operatively coupled to the lift arm and the base to counterbalance the lift arm and display. In some cases the balance mechanism includes a torquing spring member to counterbalance the lift arm and an attached display along the range of travel.

The intervertebral implant is in the form of a three-dimensional structure (10) comprising (a) a top side (1) and an underside (2) which are designed to rest against the end plates of two adjacent vertebras, (b) a left side face (3) and a right side face (4), (c) a front face (5) and a rear face (6), (d) a horizontal center plane situated between the top side (1) and the underside (2), (e) a vertical center plane (8) situated between the left side face (3) and the right side face (8) and (f) a plurality of boreholes (9) passing through the implant structure (10) that are designed to receive longitudinal affixation elements (20), the axes (19) of said elements intersecting the horizontal center plane (7). At least one of the boreholes (9) is designed in a manner that the affixation element (10) received in it can be rigidly connected to the intervertebral implant. Said connection is implemented using a thread or by matching conical surfaces.

An instructional kit suited for teaching the necessary materials, methods and techniques for conventional stick built wood structures is provided. In accordance with the present invention, a kit for stick framing a true representation of a scale house model includes all of the framing members required to build a scale model house. Specifically, the kit includes precut framing members representing each of the correct members used in actual residential construction such as studs, rafters, sills, top plates, headers, etc. Also included in the kit are wall layout plans and detailed instructions regarding the proper construction of a residential house. The intent of the kit is to provide a self contained educational tool for teaching the necessary understanding of structural wood framing.

The tank and baffle system comprises a tank for transporting liquids, having a plurality of baffles for controlling surges and excess liquid movement produced by movement of the tank. The present invention is particularly useful where there is a large ratio of tank width to tank support and lateral bending loads may be in excess of longitudinal bending. The baffles are rigidly secured to a tunnel structure that spans longitudinally from the front to the rear of the tank, and forms a continuous structure in both longitudinal and transverse directions. A further aspect of the invention is the use of chamfered corners on the baffle plates to provide fluid communication between chambers of the tank, as well as to reduce surging of the liquid contents and reduce or eliminate joint fatigue. Access ports in the baffles that are covered by access covers during use are another aspect of the invention.
摘要:
A semiconductor processing method provides for plasma-enhanced chemical-vapor deposition (PECVD) for intermetal dielectrics while minimizing risk of gate oxide impairment due to plasma discharge. A protective oxide sublayer is deposited without using high-power PECVD. The protective sublayer can be deposited by using chemical-vapor deposition (CVD) without plasma enhancement or by a lower-power PECVD. In the latter case, the initial rf power of the plasma is selected to be low enough to ensure that the gate oxide is not breached in the event of a plasma discharge. The protective sublayer can be thick enough to maintain its integrity in the event of a plasma discharge even during a higher-power PECVD deposition.

Embodiments include an apparatus for positioning items such as an electronic display, a keyboard, and/or a work surface. The apparatus can be attached proximate an edge of a generally planar support member to provide a multi-position workstation. In some cases the apparatus includes a display mount coupled to a support column and configured to support an electronic display and a keyboard. The support column may be movable with respect to support member between a sitting position and a standing position. Methods for positioning an electronic display and a keyboard are also included.
