The present invention relates to the use of compositions comprising receptor ligands obtainable by a process comprising fermenting a food material, comprising animal milk or vegetable proteins, with lactic acid bacteria to obtain a fermented food or feed material that comprises ligands of specific adrenoreceptors andor serotonin receptors. The source terminal of a low Vtp PMOS transistor is maintained at ground potential during DRAM standby mode. The nanoparticles can include TiO2 nanoparticles and quantum dots. The present invention is further directed to a method for using the record holder and scheduler. Snubber capacitors are connected in parallel with the IGBTs, respectively.
