Abstract: The present invention relates to the use of nucleic acid sequences for regulating the transcription and expression of genes, the novel promoters and expression units themselves, methods for altering or causing the transcription rate and/or expression rate of genes, expression cassettes comprising the expression units, genetically modified microorganisms with altered or caused transcription rate and/or expression rate, and methods for preparing biosynthetic products by cultivating the genetically modified microorganisms.

Abstract: Disclosed herein is a domestic injection-type ultrasonic washing apparatus comprising an oscillator module and an injector module. The oscillator module includes an oscillation circuit unit provided with various elements to generate electric vibration, ultrasonic vibrators located underneath the oscillation circuit unit and electrically connected to the oscillation circuit unit to convert the electric vibration to mechanical vibration, and a radiation plate having vibrator seating openings. The injector module includes a raw water inlet portion, a fluid passage housing having an inner fluid passage to allow inlet raw water to pass while coming into contact with the radiation plate, and injection nozzles to ultrasonically vibrate and inject the raw water. The washing apparatus achieves reduction in the size thereof, and ease of assembly, repair and exchange of damaged modules. Also, the washing apparatus shows improved radiation effect and uniform supply of wash water.

Abstract: A process for soldering a pad on a first substrate to a pad on a second substrate comprises: Coating the first substrate with a solder mask having a first thickness so that the solder mask leaves exposed the pad on the first substrate; coating the second substrate with a solder mask having a second thickness so that the solder mask leaves exposed the pad on the second substrate, the first and second thicknesses of the solder masks being selected so that the solder masks on the first and second substrates contact one another and define a solder mask wall when the first and second substrates are positioned adjacent one another so that the pads are substantially aligned; providing solder to at least one of the pads; placing the first and second substrates adjacent one another so that the pads are substantially aligned; and reflowing the solder to join the pads, the solder mask wall preventing liquid solder from flowing beyond the solder mask wall.

Abstract: Provided are an apparatus and method of dividing virtual sites using policy properties in multiprotocol label switching (MPLS) networks. In this method, when multiple virtual sites are selected with respect to one interface, not only usually used source IP addresses and VLAN tags but also TOS fields and MPLS labels are used so that more various kinds of virtual sites can be selected. Also, since the TOS fields and MPLS labels can express additional QoS-related information, differentiated services can be provided by selecting a wider variety of kinds of virtual sites.
