摘要:
A recombinant gram-negative bacterial cell comprising one or more of the following mutated protease genes: a) a mutated Tsp gene, wherein the mutated Tsp gene encodes a Tsp protein having reduced protease activity or is a knockout mutated Tsp gene; b) a mutated ptr gene, wherein the mutated ptr gene encodes a Protease III protein having reduced protease activity or is a knockout mutated ptr gene; and c) a mutated DegP gene encoding a DegP protein having chaperone activity and reduced protease activity; wherein the cell is isogenic to a wild-type bacterial cell except for the mutated Tsp gene and/or mutated ptr gene and/or mutated DegP gene and optionally a polynucleotide sequence encoding a protein of interest.

A method of selecting potential hires for progression through a hiring process is provided. The method comprises selecting at least one performance indicator for a position, obtaining the at least one performance indicator for a plurality of incumbents in the position, and placing each incumbent in the plurality of incumbents along a performance continuum according to their performance indicator. The method also comprises surveying incumbents from at least both halves of the performance continuum, generating an ideal profile for the position based upon the incumbent survey and the at least one performance indicator of the incumbents, using a survey to generate a candidate profile of a potential hire, comparing the candidate profile of the potential hire with the ideal profile for the position to determine a result for the potential hire, and determining whether to progress the potential hire to a next stage in the hiring process based upon the result.

A system for detecting and remediating a discharge of fuel from a fuel source facility is disclosed. The system can comprise a contamination detection subsystem configured to detect a discharge of fuel from the fuel source facility and a remediation subsystem configured to remediate contamination due to the discharge of fuel. A controller can automatically activate the remediation subsystem upon detection of a discharge by the contamination detection subsystem. The controller can automatically send a notification that a contamination has been detected and the remediation system has been activated. Alternatively or in addition, the controller can automatically send a notification that a contamination has been detected and the remediation system has been activated.

A system and a kit can be used for onboard, real-time blending for electronic pickups to produce various tonal combinations. In one example, at least one of the electronic pickups has dual coils. The dual coil pickup can be electrically connected to a switching circuit positioned on a stringed instrument. The switching circuit can be adjustable in real-time to select between at least two conditions for a signal of the dual coil pickup. In one instance, the conditions can select north coil only, series wiring of the dual coils, or south coil only. Alternatively, the conditions can select series wiring or parallel wiring of the dual coils. Each of the electronic pickups is electrically connected to a taper circuit positioned on the instrument. Each taper circuit is adjustable in real-time to vary an amplitude of the signal from the respective electronic pickup for output of the instrument.

A curable composition is provided comprising an oligomer having a plurality of pendent and/or terminal ethylenically unsaturated, free-radically polymerizable functional groups, a free-radically polymerizable crosslinking agent, and/or a diluent monomer, and a photoinitiator. The composition, when cured, is non-yellowing, exhibits low shrinkage and low birefringence making it suitable for many optical applications such as optical lenses, optical fibers, prisms, light guides, optical adhesives, and optical films.

The Portable Outdoor LED Illumination Apparatus provides nighttime illumination of an outdoor area for campers and other outdoor enthusiasts. The apparatus includes a vertical, tubular support pole and an illumination head assembly. The vertical, tubular support pole is comprised of a plurality of segments which are connected via springs internal to the segments. The springs allow easy collapse of the vertical, tubular support pole into a transportable unit. The segments, and therefore the vertical tubular support pole, are hollow and allow for an electrical conductor to pass from a compartment housing a plurality of batteries to the illumination head assembly. The illumination head assembly, which is comprised of a plurality of light emitting diodes (“LED's”) fixed within an epoxy potting, is affixed in such a manner so that when the LED's are powered the light is directed in the general direction of the ground.
