Abstract:
An LED lamp includes a cylindrical tube and two lamp holders fixed on two ends of the cylindrical tube. The cylindrical tube comprises a lampshade, a lamp plate, and a heat dispersing plate. The heat dispersing plate further comprises a base portion and two fastening portions. Two free edges of the base portion comprise two supports extending toward each other. The fastening portions are connected to the supports correspondingly, and the lamp shape and the lamp plate are fixed to the fastening portions correspondingly. Two lamp holders are fixed to opposite ends of the cylindrical tube, and each of the lamp holders comprises a hollow shell and a protrusion formed on an inner wall of the hollow shell. The protrusion resists against one end of the supports to prevent the lampshade from rotating relative to the heat dispersing plate.
Abstract:
A process is disclosed for fabricating narrow line-width yttrium iron garnet (YIG) disks suitable for microwave applications. The process comprises forming an epitaxial thin film of yttrium iron garnet, containing from about 0.5 to 1.5 atom percent trivalent lanthanum ions on the dodecahedral sites, on a substrate such as gadolinium gallium garnet (GGG), forming a thin layer of SiO.sub.2 on the YIG film, forming a photoresist mask layer on the SiO.sub.2 layer, removing portions of the photoresist mask layer to expose portions of the underlying SiO.sub.2 layer, removing portions of the SiO.sub.2 layer to expose portions of the underlying YIG layer and removing the exposed portions of the YIG layers to form isolated La:YIG disks supported on the GGG substrate. The substrate is then further processed, as by dicing, to provide individual La:YIG disks for fabrication into microwave devices. Linewidths of about 0.45 Oe are obtained by the process.

Abstract:
A cable receiving apparatus include a hollow base defining a through hole, a hollow conduit including a threaded end. The threaded end passes through the through hole and engages a nut to connect the hollow conduit to the hollow base. The threaded end defines a first slot for a cable running through the hollow conduit to enter the hollow base. In this way, during the assembly process, operators can assemble the cable first, then use a socket wrench to screw the nut directly.

Abstract:
The present invention belongs to the field of molecular biology. Specially, the invention relates to the screenings of a new drug target, a vaccine antigen and a test target of anti-tuberculosis treatment. Specially, based on the differential proteome technology and by the techniques of gene sequencing, in vitro protein expression, immunological detection and gene recombination, the invention primarily certifies that the up-regulated expression of Protein Rv2629 and the mutation of Gene 191A/C of Mycobacterium tuberculosis are related to the Rifampicin (RFP) drug-resistance, which provides useful information for the drug-resistance detection of Mycobacterium tuberculosis, the novel drug design and the vaccine development. Firstly, the drug-resistant strains are cultured and the proteins from drug resistance strains and sensitive strains are isolated respectively. Secondly, the proteins from the drug resistance strains and the sensitive strains are compared to determine the differential protein sites, such that the drug-resistant proteins are identified by means of Mass Spectrometry. Next, the up-regulated expression of Protein Rv2629 and the mutation of gene are correlated to the drug-resistance of Mycobacterium tuberculosis by means of gene sequencing technique. Finally, after the gene cloning, the in vitro expression and purification of the protein, the wild-type and mutant-type recombinant protein of Rv2629 are obtained. The polyclonal antibody is prepared, and the protein subcellular localization is carried out. The Minimum Inhibitory Concentrations (MICs) of the strains containing different plasmids obtained by the transformation of recombinant shuttle plasmids are also measured. The gene encoding the protein Rv2629 in the genome of Mycobacterium tuberculosis is isolated and is up-regulation expressed in a Rifampicin (RFP)-resistant strains. And the A/C gene mutation at nucleotide 191 which is related to drug-resistance is detected. The relationship between the mutation and the Rifampicin (RFP)-resistance is primarily certified by molecular biology technique and the in vitro experiments. This invention provides methods used to accurately isolate and identify the drug-resistance protein of Mycobacterium tuberculosis. The A/C mutation of Rv2629 at nucleotide 191 related to the drug-resistance of Mycobacterium tuberculosis is isolated, which shows new approach for the further study of Mycobacterium tuberculosis drug-resistant mechanism, the rapid detection of clinical drug-resistance strains, as well as the developments of new drug targets and vaccines.
