چکیده
We separate many of the basic fragments of classical logic which are used in constructive reverse mathematics. A group of related Kripke and topological models is used to show that various fragments of the Weak Law of the Excluded Middle, the Limited Principle of Omniscience, and Markov’s Principle, including Weak Markov’s Principle, do not imply each other.

We separate many of the basic fragments of classical logic which are used in reverse constructive mathematics. A group of related Kripke and topological models is used to show that various fragments of the Weak Law of the Excluded Middle, the Limited Principle of Omniscience, and Markov’s Principle, including Weak Markov’s Principle, do not imply each other. §
متن کاملIsolation of the Gene Coding for Movement Protein from Grapevine Fanleaf Virus
A pair of degenerate primers, GMPF1 and GMPR1, was designed on the basis of alignment of previously reported Grapevine fanleaf virus (GFLV) movement protein (MP) nucleotide sequences from Iran and other parts of the world. cDNA was synthesized by the use of Oligo d(T)18 from total RNA extraction from each diseased grapevine leaf sample and subjected to polymerase chain reaction (PCR) with the d...

متن کاملEffects of cadmium chloride as inhibitor on stability and kinetics of immobilized Lactoperoxidase(LPO) on silica-coated magnetite nanoparticles versus free LPO
Objective(s): Enzyme immobilization via nanoparticles is perfectly compatible against the other chemical or biological approximate to improve enzyme functions and stability. In this study lactoperoxidase was immobilized onto silica-coated magnetite nanoparticles to improve enzyme properties in the presence of cadmium chloride as an inhibitor. Materials and Methods: The process consists of the ...
متن کاملResonance Raman spectroscopy reveals pH-dependent active site structural changes of lactoperoxidase compound 0 and its ferryl heme O-O bond cleavage products.
The first step in the enzymatic cycle of mammalian peroxidases, including lactoperoxidase (LPO), is binding of hydrogen peroxide to the ferric resting state to form a ferric-hydroperoxo intermediate designated as Compound 0, the residual proton temporarily associating with the distal pocket His109 residue. Upon delivery of this "stored" proton to the hydroperoxo fragment, it rapidly undergoes O...
