A method for screening cells with high level expression of a target protein is disclosed. The method includes introducing into a plurality of host cells a DNA construct that encodes both a target protein and an inhibitor to an endogenous selectable marker in the host cells, screening host cells harboring the DNA construct for the expression of the endogenous selectable marker, and isolating cells with reduced expression of the selectable marker. Also disclosed is a DNA construct configured to express both the target protein and the inhibitor inside the host cell.

A method for adjusting and testing an image sensor module is provided. The method of the present invention includes steps of: (1) calculating longitudinal and transverse deviation values of a center point of a lens relative to a standard reference position specified on a lens barrel, and an angle deviation value of the lens according to position signals of the lens on the image sensor module; (2) compensating the longitudinal and transverse deviation values of the center point of the lens, and the angle deviation value of the lens for exactly positioning the lens; and (3) adjusting focus of the image sensor module. The method of the present invention can compensate the mechanism errors produced in the mounting process of the image sensor module for conveniently and exactly adjusting the focus of the image sensor module. An apparatus for adjusting and testing an image sensor module is also provided.

A handheld electronic device and an operating method thereof are provided. The handheld electronic device includes a first body, a second body, and a moving assembly. The moving assembly includes a sliding module and at least one rotating module. The sliding module is coupled to the second body, wherein the second body is moveable between a first position and a second position. The rotating module is coupled between the first body and the sliding module so that the second body is rotated relative to the first body. The second body is automatically rotated from the second position to a third position to form a first angle with the first body. The second body can be rotated between the third position and a fourth position to form a second angle with the first body, wherein the second angle is greater than the first angle.

A method is disclosed for controlling a methanol carbonylation process for producing acetic acid. The method includes the steps of monitoring the rate of production of the acetic acid; reducing the production rate in response to a change in a process condition or a process equipment condition; after the production rate is reduced, controlling the process at the reduced production rate; and increasing the production rate after the condition change has been addressed until at least the production rate returns to a normal operating range; wherein during at least one of the steps of reducing the production rate, controlling the process at the reduced production rate, and increasing the production rate until the production rate returns to a normal operating range, the process is controlled by nonlinear multivariable control based on a model of the process.Also disclosed is a process for producing acetic acid, in which at least a reaction section of the process is controlled using a multivariable nonlinear predictive controller based on a nonlinear model of the process. Control of the process is based on the same model during normal operations, during process-upset conditions and also during a recovery period after the upset has been addressed.

A scroll compressor including a block, a fixed scroll, an orbiting scroll, a crankshaft, an Oldham ring and an oil passage is provided, wherein the fixed scroll is fixed on the block, and the orbiting scroll, the crankshaft and the Oldham ring are disposed on the block. The fixed scroll and the orbiting scroll form a gas-in area, a compressing area and a gas-out area which are connected in a series. The orbiting scroll is eccentric connected with the crankshaft to orbit over the fixed scroll and drive the Oldham ring moving. A reciprocating motion area on the block is formed via the reciprocating motion between the block and the Oldham ring, wherein the block has an oil opening in the reciprocating motion area. Besides, one terminal of the oil passage is connected to the oil opening, and another terminal of the oil passage is connected to the gas-in area and the compressing area.
