  • Publication number: 20240047971
    Abstract: A hydro-photovoltaic complementary operation chart application method for a clean energy base includes: divide a hydro-photovoltaic complementary operation chart into two sub-operation charts by runoff probability and critical probability; predict runoff and predicted photovoltaic output during the operation cycle, select the sub-operation chart by the runoff probability, determine hydropower output of a reservoir in the current month according to water level of the reservoir at the beginning of the current month and the operation area, and obtain the water level of the reservoir at the end of the current month through the runoff calculation; obtain long-term hydropower output process and reservoir level process in the clean energy base until the hydropower output and water level of the reservoir in all months of the operation cycle are calculated, and calculate hydropower generation probability to complete operation.

  • Patent number: 9476087
    Abstract: The present invention relates to compounds for and a method of detecting beta-lactamase activity in a sample. The sample is contacted with a nanoparticulate tag. The nanoparticulate tag comprises a metal or a combination of metals, or it comprises a nanotube of a metal, boron nitride and/or carbon. The respective metal is capable of forming one of a covalent bond, a coordinative bond and a non-covalent interaction with a thio or a seleno group. The sample is contacted with a compound of one of general formulas (I)-(III) and (VII)-(IX). At least one beta-lactam moiety of the compound is cleaved by the beta-lactamase activity in the sample. As a result a cleavage moiety Z-A-Z, Z-A-Z—R15, Z-A-Z—R16, Z-A-Z—R17, Z-A-Z—R18 or Z-G-N(R8)R9 is released that is immobilized on the surface of the nanoparticulate tag by a covalent bond via a Z atom. The presence of beta-lactamase activity is determined based on the presence of the cleavage moiety immobilized onto the surface of the nanoparticulate tag.
