摘要： Disclosed is a diacylglycerol acyltransferase 1, a recombinant Saccharomyces cerevisiae containing the diacylglycerol acyltransferase 1, and application thereof in production of triacylglycerol. The diacylglycerol acyltransferase 1 of the invention has a function of catalyzing synthesis of triacylglycerol. After the recombinant Saccharomyces cerevisiae containing the diacylglycerol acyltransferase 1 of the invention is subjected to induction culture for 48 h, the content of total fatty acid and triacylglycerol in the recombinant Saccharomyces cerevisiae containing the diacylglycerol acyltransferase 1 can be respectively increased by 1.94 folds and 12.09 folds as compared with those of Saccharomyces cerevisiae without the recombinant diacylglycerol acyltransferase 1. The instant invention provides a method for improving the ability of microorganisms to produce polyunsaturated fatty acids (PUFAs) by means of genetic engineering.

摘要： An electrically conductive ceramic composite conductor configured for downhole operations includes a first portion formed from an electrically non-conductive ceramic material having a first coefficient of thermal expansion (CTE). The first portion includes an outer surface. A second portion is disposed radially inwardly of the outer surface. The second portion is formed from an electrically conductive ceramic material having a second CTE that is substantially similar to the first CTE.

摘要： A drain floor, including a drain base, a drain body including a cavity, a drain cup, a supporting frame; and a reset member. The drain cup includes a cup body, a stem, and a base. The cup body includes a through hole, and two ends of the stem are connected to the cup body and the base, respectively. The cup body is disposed in the cavity and the base is disposed out of the cavity. The space between the drain body and the drain cup forms an annular channel, and the annular channel communicates with the through hole. The annular channel includes a water inlet and a water outlet. The reset member is connected to the drain cup and is movable with respect to the drain cup to open and close the water outlet. The supporting frame connects the drain body and the reset member.

摘要： Devices and methods related to high-contrast liquid crystal displays (LCDs) are provided. For example, such an electronic device may include an LCD with two liquid crystal alignment layers not symmetric to one another and upper and lower polarizing layers respectively above and below the alignment layers. Light transmittance through the plurality of pixels may increase monotonically with gray scale voltage. The display may operate using a gray scale level 0 voltage higher than a minimum gray scale level 0 voltage capability of the display. Additionally or alternatively, liquid crystal molecular alignment axes of the two alignment layers may be offset from one another by an angle other than a multiple of 180 degrees. Additionally or alternatively, a first polarizing axis of the upper polarizing layer or a second polarizing axis of the lower polarizing layer, or both, may be neither parallel nor perpendicular to one of the liquid crystal molecular alignment axes.
