The AgOAc-catalysed reaction of 3-nitro-2-phenyl-2H-chromenes with stabilized azomethine ylides generated from the imines Girls Bag based on methyl glycinate and arylaldehydes leads to a mixture of endo and endo’ isomers of the corresponding chromeno[3,4-c]pyrrolidines in a ratio of 2.0–2.3:1 in 85–93% total yields as a result of a Michael ad
In most quantum sensing schemes, interactions between the constituent particles of the sensor are expected to lead to thermalization and degraded sensitivity.However, recent theoretical and experimental work has shown that the phenomenon of quantum many-body scarring can slow down, or even prevent, thermalization.We show that scarring can be exploi
Although the combined cooling, heating and power (CCHP) microgrid is feasible for achieving a high energy utilization efficiency, the fluctuation of energy sources, NHL packs such as a photovoltaic system and multiple loads, may affect the safety, economics and stability in CCHP microgrid operation.For this reason, this paper establishes a mathemat
Object To investigate the antibacterial activity of Camellia sinensis, Juglans Media Chest regia and Hippophae rhamnoides extracts on methicillin-resistant strains of Staphylococcus epidermidis and Staphylococcus hemolyticus.Background Coagulase negative staphylococci (CoNS) which were once considered avirulent and usually contaminants when isolate
Introduction: Tasikmalaya Regency is one of the areas in West Java that has a large industrial potential, especially small and handicraft industries.Every workplace, both formal and informal, has various potential hazards that can affect the health of workers or can cause occupational diseases.As bamboo is sharp, the craftsmen must be very careful
