Abstract: The impact of plastid size change in both monocot and dicot plants has been examined. In both, when plastid size is increased there is an increase in biomass relative to the parental lines. Thus, provided herein are methods for increasing the biomass of a plant, comprising decreasing the expression of at least one plastid division protein in a plant. Optionally, the level of chlorophyll in the plant is also reduced.

Abstract: Disclosed herein are transgenic plants and plant cells having increased photosynthetic rate, increased biomass production, and/or improved cold tolerance compared to control plants (such as non-transgenic plants of the same species as the transgenic plants). In some examples, the transgenic plants/plant cells contain a plant transformation vector including a nucleic acid encoding a pyruvate orthophosphate dikinase (PPDK) polypeptide. Also disclosed herein are methods for making the transgenic plants, for instance by introducing into progenitor cells of the plant a plant transformation vector including a nucleic acid that encodes a PPDK polypeptide, and growing the transformed progenitor cells to produce a transgenic plant, in which the PPDK nucleic acid is expressed. Further disclosed herein are PPDK-encoding nucleic acids, PPDK polypeptides, and plant transformation vectors of use in producing the transgenic plants or plant cells.

Abstract: Silicon-based high pressure sensor modules are manufactured in an array arrangement, incorporating a low temperature cofired ceramic (LTCC) substrate. The LTCC substrate can withstand high pressures. Bossed containers filled with oil are mounted on the substrate in an array. These bossed containers house the sensor cells which are composed of a sensor handle wafer and a diaphragm. The top surface of these bossed containers are flexible and deflect under pressure. By controlling the surface area and the thickness of the top surface, the pressure sensors can be configured to measure a wide range of pressures. The oil transfers pressure from the bossed container to the diaphragm of the sensor cell while protecting the sensor cell from high pressures and harsh media.

Abstract: A sensor module is provided having a compact housing containing a sensor. A low temperature co-fired ceramic substrate is located on the housing. The sensor and signal processing circuitry are located on the low temperature co-fired ceramic substrate. The sensor module further includes a metal shield substantially encapsulating the sensor.

Abstract: A process for preconditioning assembled parts for leak testing is disclosed. The process includes placing the assembled parts under vacuum to draw out through any unsealed interface of the assembled parts any fluid trapped therein, and while under vacuum, exposing the assembled parts to a liquid conditioning medium (LCM), wherein the LCM may comprise a mixture of water and a low vapor pressure surfactant. The assembled parts exposed to the LCM are then placed under positive pressure greater than ambient pressure to drive the LCM into any unsealed interfaces of the assembled parts. Any residual LCM on the external surfaces of the assembled parts is then removed, and the assembled parts are subsequently tested for LCM ingress.
