Abstract: A genome-specific gene sequence fragment of female Acipenser Dabryanus and a method for identifying the sex of Acipenser Dabryanus are disclosed. The gene sequence fragment of Acipenser Dabryanus is used to identify the sex of Acipenser Dabryanus. The method includes: performing PCR amplification on the DNA of the Acipenser Dabryanus to be tested, and judging that the Acipenser Dabryanus to be tested is female when a resultant product from the amplification shows 3 bands on an agarose gel and the Acipenser Dabryanus to be tested is male when a resultant product from the amplification shows 2 bands on an agarose gel, alternatively, judging that the Acipenser Dabryanus to be tested is female when a resultant fragment from the amplification has a 1402 bp band and it is male if there is no 1402 bp band. The gene sequence fragment is used to quickly and efficiently identify the sex of Acipenser Dabryanus.

Abstract: The present application relates to the technical field of removing a section steel concrete column, and more particularly, the present application relates to a method for removing a section steel concrete column, comprising: determining a pre-blasting portion of the section steel concrete column according to a height dimension of the section steel concrete column; cutting a pre-blasting portion to obtain an initiation position, part of section steel being exposed at the section steel concrete column at the initiation position; a blasting object being provided at the part of section steel at concrete at the initiation position, the blasting object provided at the part of the section steel being a linear energy-concentrating cutter; detonating the blasting object to remove the section steel concrete column.

Abstract: Problem Diagnosis Automation System (PDAS) automates the diagnosis of repetitive problems and the enforcement of preventive measures across a network. Automation assets across the network include Network Intent (NI) inside the no-code platform. A Network Intent Cluster (NIC) clones a NI across the network to create a group of NIs (member NIs) with the same design or logic. A subset of Member NIs can be executed according to user-defined conditions based on the member device, the member NI tags, or signature variables. A Triggered Automation Framework (TAF) matches the incoming API calls from a 3rd party system to current incidents and installs the automation (e.g., NI/NIC) to be triggered for each call. It may include: Integrated IT System defining the scope and data of the incoming API calls; Incident Type to match a call to an Incident; and Triggered Diagnosis to define what and how the NIC/NI is executed.

Abstract: The present invention discloses an air-fried type food processor, including: a body, which is provided with a frying barrel cavity; a frying barrel capable of being taken out of or placed in the frying barrel cavity; and an upper heating system arranged in the body and located above the frying barrel cavity, the upper heating system includes an upper heating tube and an upper heating tube support for fixing the upper heating tube, the upper heating tube has a disc-shaped spiral structure, the upper heating tube support is fixed to N pipelines on outermost rings of the upper heating tube. Deformation of a tube body of the upper heating tube is reduced, and the frying barrel is prevented from coming into contact with the upper heating tube in the process of being taken out of the frying barrel cavity or pushed into the frying barrel cavity.

Abstract: The disclosure discloses a mutant of nitrile hydratase derived from Caldalkalibacillus thermarum, and belongs to the technical field of enzyme engineering. The nitrile hydratase mutant Cal. t Nhase-A20V provided by the disclosure has a half-life of about 10 min at 70° C., which does not change much compared with the thermal stability of the wild enzyme. The specific enzyme activity of the mutant Cal. t Nhase-A20V is 128% of that of the wild enzyme. At the same time, the mutant also has better tolerance to a substrate and a product, and the final yield of nicotinamide produced by whole-cell catalysis reaches 598 g/L. Therefore, the nitrile hydratase mutant Cal. t Nhase-A20V provided by the disclosure has good enzymatic properties and is beneficial to future industrial production.

Abstract: The present invention relates to the preparation of compounds of Formula I, including thapsigargin, nortrilobolide and 8-O-debutanoyl-thapsigargin from commercially available (R)-(?)-carvone via synthetic intermediate compound of formula 12 by pinacol coupling and in situ lactonization.

Abstract: A system manages a network using a graphical user interface (GUI) that maps the network. The mapping includes a topology of network layers and includes the generation of a path through the network, which may use virtualization technology. The path may be an AB network path that is automatically discovered and may be compared with a golden path.
