Interference is a critical problem for memory systems and a primary cause of retrieval failure. One strategy for minimizing interference is to associate the items to be remembered with the context in ...
Methodological interference of biochar in the determination of extracellular enzyme activities in composting samples
Biochar the trap of carbon soil fertility hydrolysis enzyme assay phosphatase
2015/1/6
Biochar application has received increasing attention as a means to trap recalcitrant carbon and enhance soil fertility. Hydrolytic enzymatic assays, such as β-glucosidase and phosphatase activities, ...
The origin of the phase in the interference of Bose-Einstein condensates
The condensation condensation wave function treatment the particles
2014/12/20
We consider the interference of two overlapping ideal Bose-Einstein condensates. The usual description of this phenomenon involves the introduction of a condensate wave function with a definite phase....
Evolution of additional (hidden) quantum variables in the interference of Bose-Einstein condensates
Additional variable hidden variables quantum mechanics the high concentration condensate
2014/12/20
Additional variables (also often called “hidden variables”) are sometimes added to standard quantum mechanics in order to remove its indeterminism or “incompleteness” and to make the measurement proce...
Interference of Bose-Einstein condensates: Quantum nonlocal effects
Quantum measurement quantum system condensate particle measurement and quantum mechanics
2014/12/19
Quantum systems in Fock states do not have a phase. When two or more Bose-Einstein condensates are sent into interferometers, they nevertheless acquire a relative phase under the effect of quantum mea...
Studies of the complex of ribosomal protein L1 with its binding site in 23S rRNA: Modification -interference, mutagenesis and crosslinking
Ribosomal proteins escherichia coli ribosomes the protein spiral protein
2014/12/11
Interaction of ribosomal protein L1 and the 23S rRNA plays an important role in both the structure and biological activity of the Escherichia coli ribosome. We have minimized the binding site for prot...
