Abstract: Disclosed herein are an apparatus and a method for controlling PWM switching frequency that employ a negate PWM scheme to thereby increase PWM switching frequency, improve control responsiveness, and reduce the size of the circuit. The apparatus includes: a power factor correction (PFC) converter configured to convert an AC voltage into a DC voltage, the converter comprising a transistor controlling an operation of the PFC converter and a current sensor for measuring an electric current flowing through the transistor; and a controller configured to receive an output from the current sensor and calculate a duty ratio of a switching signal applied to a gate terminal of the transistor. The controller applies the calculated duty ratio to the switching signal in an on-duty period of the switching signal.

Abstract: The present disclosure relates to, inter alia, a gene for increasing biomass production isolated from Arabidopsis thaliana, and a method for producing a transgenic plant by using the same. More specifically, the present disclosure provides, inter alia, a composition for increasing production of plant biomass, a recombinant expression vector and a transgenic plant, comprising a base sequence encoding for the amino acid sequence of sequence number 2. Consequently, by using the gene for increasing biomass production of the present disclosure, it is possible to obtain a transgenic plant with which the amount of biomass production is increased and, ultimately, by using the same, it can be expected to be possible to increase starting materials for the pulp and papermaking industries, and starting materials for bioethanol.

Abstract: Provided are a composition containing ABI3 gene and a method of delaying flowering of plants using the same. The method has an excellent effect on delaying of flowering of plants. In the previously known method of delaying the flowering of plant, since flowering is delayed by silencing the expression of a gene for promoting flowering, it is difficult to regulate a degree of delaying of flowering. Also, since a gene silencing method such as RNAi is used, it is not easy to produce an actual transgenic plant and thus it is difficult to use for industry. However, ABI3 gene acts in a manner which delays flowering when expression increases, and thus it is easy to regulate the degree of delay in flowering and to produce a transgenic plant. Thus, it is expected that the present disclosure can be effectively applied to increase the productivity of crops by delaying flowering time or blocking flowering in plants of which vegetative tissue or leaves are used.

Abstract: A grit chamber for a wastewater treatment plant. A vertical floodgate is installed on a partitioning wall and is driven in a vertical direction to be opened downwardly from a top toward a bottom. A floodgate driving motor is coupled to one end of the vertical floodgate to directly drive the vertical floodgate. An inflow amount measurement means functions to stepwisely measure a flow amount of wastewater which passes through a wastewater tank. A control section is connected to the floodgate driving motor and the inflow amount measurement means to control the floodgate driving motor in response to a measurement result of the inflow amount measurement means. A wastewater level is adjusted within a predetermined range through operation of the vertical floodgate to maintain a constant flow velocity of wastewater which passes through a sand sedimentation zone, thereby preventing organic material which is contained in the wastewater and is other than sand, from sedimenting.

TALP is prepared by a process which comprises the steps of homogenizing mammalian tissue, obtaining supernatant after centrifugation, and fractionating the supernatant thus obtained by cation-exchange chromatography and hydroxyapatite chromatography. TALP of the invention promotes tubulin polymerization without GTP, like taxol, and the microtubules thus polymerized are resistant to disassembly caused by Ca2+ and cold temperature under 4° C. and highly stabilized. Moreover, TALP of the invention inhibits cell proliferation, regeneration of scraped NIH 3T3 cell, proliferation and in vitro motility of HM7 human colon cancer cell, cell division of fertilized Xenopus oocyte, binding of tau protein to tubulin molecule, and E. coli lysis caused by virus.
