Background
Using the electroporation process, electrical pulses create pores that allow genetic material to permeate the bacterial membrane of electrocompetent cells. The limiting factor for this standard laboratory method is the efficiency by which DNA can be introduced into E. coli. Commercially available electrocompetent cells are being delivered frozen at about -70 to -80°C. The conventional wisdom is that storage at a higher temperature, for example at -20°C or higher, will result in a significant decrease in viability and transformation efficiency.

Invention

Inventors of Saarland University have established a new method and created a new bacterial strain to generate electrocompetent bacterial cells with a transformation efficiency of up to 5,6 x 1010, which can be handled at room temperature. This electrocompetent cells can be stored at 4°C without losing transformation efficiency. Also the new established protocol is able to improve the transformation efficiencies of commercially available bacterial cells.

The invention can be used for cutting high-strength materials, e. g. during disassembly of nuclear power plants, in under water or offshore applications. Benefits: Immediate start or stop the cutting operation possible; davings of abrasive suspension and time; efficiency improvement.

The technology consists of a new algorithm for the control of the charging pressure in turbocharged engines. It enables a secure and efficient usage of the engine without need for additional cost intensive parts. It is highly suitable for all kinds of internal combustion engines in all classes.

Acoustic measurements are often subject to unwanted background noise, which compromise the validity of noise measurements. By using a statistical prediction model the invention automatically identifies the disturbed sections and then systematically suppresses these areas in the level detection. In contrast to the frequently used method of percentile ranks the inventive method is not fixed to fixed proportions of background noise.

This invention for the examination of metallic nanoparticles in a sample exploits the plasmonic properties of metals. A metal tip with a Raman-active coating is used as a sensor to converge on the particle to be examined. The tip and particle form a resonator structure in the case of a metallic nanoparticle. This resonator structure causes the Raman signal belonging to the sensor coating to be amplified and thus enables the metallic particle to be identified under normal conditions.

This is a device for patients self-determination of implanted cardioverter-defibrillators (ICD) therapy delivery. Depending on symptoms of the patient, he can decide himself to abort or delay ICD-therapy and thereby effectively
prevent inappropriate ICD therapy.
