Abstract: 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%.

Abstract: Provided is a noninvasive hemoglobin detector, including an image acquisition system, an image processing and analysis system and a printing device. The image acquisition system is connected with the image processing and analysis system, and the image acquisition system is used for acquiring, transmitting and storing an image to be tested. The image processing and analysis system is further connected with the printing device, and the image processing and analysis system is used for processing and analyzing the image to be tested to obtain an analysis result. The printing device is used for printing the image to be tested and the analysis result.

Abstract: The present invention relates to an intelligent motorized curtain mechanism, wherein a first mounting box, a second mounting box, a bead chain length adjustment mechanism and a bead chain are provided, and a power control mechanism and a master drive mechanism are fixedly installed inside the first mounting box. The power control mechanism is arranged to drive the master drive mechanism, which forms a synchronous belt connecting with the bead chain through the slave mechanism and enables the master drive mechanism to move the bead chain.

Abstract: The present invention relates to an assembled annular light supplement lamp, including a first splicer and a second splicer that are spliced to form a ring, where both ends of the first splicer and the second splicer are provided with a first end face and a second end face respectively, and the first end face is in plug-in connection with the adjacent second end face. By arranging the first splicer and the second splicer, where one or a plurality of second splicers may be provided, splicing or disengagement is realized by the matching between a first guide pin and a first slot, so that the assembled annular light supplement lamp is easy to install and use, and reduces the storage space and transportation costs after disassembly.
