Method for recycling urea-formaldehyde (UF) and raw materials from wood-based panel, and use thereof
Patent number: 11958942Abstract: The present disclosure provides a method for recycling urea-formaldehyde (UF) from a wood-based panel. In the present disclosure, the UF is depolymerized by an ultrasonic treatment, and depolymerized UF can be reused for UF manufacture and wood-based panel production. The recycled and treated UF can be repeatedly used in wood-based panel manufacture without affecting performances of the wood-based panel. UF-glued wood-based panels can be recycled, and a recycled wood-based panel raw material can replace at least 50% of a non-recycled wood-based raw material for particle board production without affecting performances of the wood-based panel.Type: GrantFiled: April 10, 2023Date of Patent: April 16, 2024Assignee: Southwest Forestry UniversityInventors: Hui Wan, An Mao, Hong Lei, Xiaojian Zhou, Zhi Li, Long Yang, Linkun Xie, Guanben Du -
Patent number: 11954122Abstract: In an example embodiment, a solution is used to provide container volume replication via a container storage replication log and volume buffer synchronization, which is built on top of a container cloud platform whose container metadata and replication runtime configuration are all managed by a storage manager (a service orchestrated by its job scheduler and service orchestrator). This container volume replication ensures the data security for a long-running service in the container. In the case of any disaster, the in-memory database and application data inside of the container can be recovered via volume replication. This provides container volume replication for long-running containerized applications whose states keep changing.Type: GrantFiled: January 23, 2023Date of Patent: April 9, 2024Assignee: SAP SEInventors: Long Du, Yu Wang

Publication number: 20240067996Abstract: The invention provides a Saccharomyces cerevisiae strain for producing a human milk lipid substitute. By integrating a heterologous lysophosphatidic acid acyltransferase into Saccharomyces cerevisiae and knocking out its own natural lysophosphatidic acid acyltransferase, the content of palmitic acid (C16:0) at Sn-2 position of triacylglycerol produced by Saccharomyces cerevisiae is increased, to synthesize a human milk lipid substitute. On this basis, a metabolic pathway related gene is knocked out, to further increase the content of human milk lipid substitute in the product. In the present invention, a human milk lipid substitute is de novo synthesized by Saccharomyces cerevisiae for the first time, in which the total fatty acid is 15% or more, and the relative content of C16:0 at Sn-2 position reaches about 60%.Type: ApplicationFiled: November 1, 2023Publication date: February 29, 2024Inventors: Long LIU, Jian Chen, Xueqin LV, Wenyang Wu, Guocheng Du, Jianghua Li, Guolin Zhou, Yanfeng Liu, Chenyang Zhang

Patent number: 11803514Abstract: In an example embodiment, a solution is used to provide for a highly efficient image dispatch system for container-based in-memory databases in a database-as-a-service framework that provides storage and bandwidth cost savings and introduces advanced features of container techniques. This solution makes best use of the advantages of the concurrent and distributed capabilities of in-memory databases in a database-as-a-service framework. A container operator manager provides operators for various uses, such as the “diff” operator and the “merge” operator. A dispatch manager acts as a centralized service for diff content maintenance, patch publication and management of dispatch worker nodes. A patch worker on each node has the capabilities to execute the specified patching and validation between the images located on each side of the in-memory database in the database-as-a-service framework.Type: GrantFiled: June 17, 2022Date of Patent: October 31, 2023Assignee: SAP SEInventors: Yu Wang, Long Du, Le Zhang

Publication number: 20230267224Abstract: In an example embodiment, a hardware mechanism for protecting user-level software from privileged system software is leveraged to protect in-memory databases in container implementations in a cloud. This hardware mechanism takes the form of an enclave. An enclave is a portion of a CPU that shields application code and data from accesses by other software, including higher-privileged software. Memory pages belonging to an enclave reside in the enclave page cache (EPC), which cannot be accessed by code outside of the enclave. This helps ensure that (1) applications built on top of in-memory database are securely trusted, (2) and a trusted path architecture is provided for enclaves allowing in-memory databases to run securely on top of untrusted cloud platform.Type: ApplicationFiled: April 26, 2023Publication date: August 24, 2023Inventor: Long Du

Patent number: 11681549Abstract: In an example embodiment, a new solution is provided for an in-memory database provided in a cloud as a service that enables “job cross running” instead of “parallel job running.” Specifically, job scripts are clustered based on a shared service. A primary job script in the cluster is compiled and executed, but secondary job scripts in the cluster are not compiled until after the execution of the primary job script has begun. A mock library is inserted into each of the secondary job scripts to cause service calls for the shared service in the secondary job scripts to be replaced with mock service calls. The secondary job scripts are then scheduled and executed, and upon completion the primary job script is permitted to delete the shared service.Type: GrantFiled: April 28, 2022Date of Patent: June 20, 2023Assignee: SAP SEInventors: Long Du, Le Zhang, Yu Wang
