Abstract: A modular flooring includes a plurality of floorings and a plurality of floor connectors. Each of the floorings has at least two opposite sides respectively formed with a hidden engaged hole which is a recessed structure. When the floorings are laid adjacent to each other and the corresponding hidden engaged holes of each two of the floorings are aligned with each other, each of the floor connectors is respectively inserted into the corresponding hidden engaged holes, so that the floorings adjacent to each other can be combined mutually. As a result, the assembling convenience and the flexibility of the modular flooring are increased.

Abstract: An outer layer material having an entanglement comprising an intermingling of cloaked hydrophilic guest and a hydrophobic polymer host, wherein molecules of the guest have been crosslinked with each other. Under certain circumstances, using complexes of the guest may be desirable or even necessary. Prior to intermingling with the guest, a host blend may be produced to include a physical blend of a hydrophobic polymer host and a maleated hydrophobic co-host (preferably, an anhydride functionalized hydrophobic polymer, whereby the polymer so functionalized, is the same as that selected for the host). The intermingling of the guest and host, or host-co-host blend, includes a physical tangling, whether it also comprises crosslinking by primary bonding (e.g., chemical/covalent bonding) there-between.

Abstract: A strain of xylose-utilizing Zymomonas was engineered with a genetic modification to the glucose-fructose oxidoreductase gene resulting in reduced expression of GFOR enzyme activity. The engineered strain exhibits reduced production of xylitol, a detrimental by-product of xylose metabolism. It also consumes more xylose and produces more ethanol during mixed sugar fermentation under process-relevant conditions.

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.

Abstract: Production of ethanol using a strain of xylose-utilizing Zymomonas with a genetic modification of the glucose-fructose oxidoreductase gene was found to be improved due to greatly reduced production of xylitol, a detrimental by-product of xylose metabolism synthesized during fermentation.

Abstract: A switch-mode power supply for selectively providing power from a main power source and a standby power source to an electronic device is provided. The switch-mode power supply includes a signal input, a first transistor, a second transistor, a driving circuit, and a switching circuit. The signal input is used for receiving a control signal. The driving circuit and switching circuit connect the signal input to the gate of the second transistor in series. When the driving circuit detects the first transistor is switched off, the gate of the second transistor is immediately pulled up to open the second transistor, and when the driving circuit detects the first transistor is switched on, the gate of the second transistor is immediately pulled down to close the second transistor.

Abstract: Disclosed in the present invention is a Zymomonas integrant and derivatives of these integrants that posses the ability to ferment pentose into ethanol. The genetic sequences encoding for the pentose-fermenting enzymes are integrated into the Zymomonas in a two-integration event of homologous recombination and transposition. Each operon includes more than one pentose-reducing enzyme encoding sequence. The integrant in some embodiments includes enzyme sequences encoding xylose isomerase, xylulokinase, transketolase and transketolase. The Zymomonas integrants are highly stable, and retain activity for producing the pentose-fermenting enzyme for between 80 to 160 generations. The integrants are also resistant to acetate inhibition, as the integrants demonstrate efficient ethanol production even in the presence of 8 up to 16 grams acetate per liter media.

Abstract: A series of novel, melt- or mold-processable HA esters with varying aliphatic chain lengths are synthesized from silyl (HA-quaternary (quat.) ammonium salt complex (preferably silyl HA-CTA, a silylated HA complex with cetyltrimethyl ammonium salt). Introduction of aliphatic acyl groups, preferably acid chlorides, to disrupt the strong HA intermolecular bonding, is done via acylation. Acylation takes place at the oxygen of the trimethylsilyloxy group -0-Si(CH3)3 in the silyl HA-CTA by removal of trimethylsilyl. groups therefrom. Optionally, crosslinking may be performed during the shaping/molding of the HA esters into a structure/device, or thereafter, if at all. Native HA can then be regenerated/recovered by saponification/hydrolysis, removing acyl groups, —CH3(CH2)10CO, and the cetyltrimethyl ammonium salt groups, —CTA, from HA ester. The structure/device of a preselected shape (e.g.
