Abstract: A device for processing an abnormal sleep state of an operating system is provided. The processing device includes a detection unit, an abnormal event determination unit, an event information verification unit and an abnormality notification unit. The detection unit detects whether a screen lid closing event occurs, wherein the operating system is preset to enter a sleep mode when a screen lid is closed, and the operating system is preset to enter a wake-up mode when the screen lid is opened. The abnormal event determination unit determines whether the screen lid is closed and whether an event that the operating system is not entering the sleep mode occurs. The event information verification unit verifies an event information and determines whether the event is classified as an abnormal event. The abnormality notification unit sends an abnormality notification to a system administrator unit, which performs a processing according to power status.

Abstract: Provided are a gene combination used for controlling foreign gene expression in a specific plant tissue, and a method applying the gene combination to cultivate a transgenic plant. The method is used to cultivate, for example, an endosperm zero expression-type transgenic rice, i.e., rice grain endosperm produced by the rice does not contain any transgenic product protein synthesis and accumulation.

Abstract: A detachable and combined drive key of a power head of a rotary drilling rig is provided. The drive key includes torque transfer keys and a pressure transfer key. Each torque transfer key is respectively assembled on a key groove on an inner wall of the drive sleeve. The pressure transfer key is assembled at a bottom of a drive sleeve and includes a circular ring structure and a plurality of pressure pads. Each pressure pad has a width less than the torque transfer key. A central surface of each pressure pad is aligned with a central surface of each torque transfer key. The drive sleeve, the torque transfer keys, and the pressure transfer key are combined to form an integrated drive key with a same circular cross-section.

Abstract: Provided are an artificially designed and modified insecticidal protein or a segment thereof. The insecticidal protein belongs to a Vip3A-type insecticidal protein. The protein or the segment thereof has an insecticidal activity against a pest, especially a lepidoptera pest. Also provided are a nucleic acid for coding the protein or the segment thereof, an insecticidal composition, a DNA constructor, and a transformed microorganism or a plant comprising the nucleic acid, and a method for controlling a pest, especially a plant pest.

Abstract: The present disclosure provides a detachable and combined drive key of a power head of a rotary drilling rig. The drive key includes torque transfer keys (9) and a pressure transfer key (10). Each torque transfer key (9) is respectively assembled on a key groove on an inner wall of the drive sleeve (3). The pressure transfer key (10) is assembled at a bottom of a drive sleeve (3) and includes a circular ring structure (13) and a plurality of pressure pads (14). Each pressure pad (14) has a width less than the torque transfer key (9). A central surface of each pressure pad (14) is aligned with a central surface of each torque transfer key (9). The drive sleeve (3), the torque transfer keys (9), and the pressure transfer key (10) are combined to form an integrated drive key with a same circular cross-section.
