Let D be a non empty set, let i be a natural number, and let p be a finite sequence of elements of D. Then p i is a finite sequence of elements of D. Let D be a non empty set and let a, b be elements of D. Then 〈a,b〉 is an element of D2. Let D be a non empty set, let k, n be natural numbers, let p be an element of Dk, and let q be an element of Dn. Then pa q is an element of Dk+n. Let D be a no...

Abstract With increasing and massive photovoltaic (PV) connected to the distribution network(DN), there will be two-way power flow in traditional DN. As one indicator measure maximum amount of active that certain bus network (DN) can injected, hosting capacity DN is a research hotspot. This calculation method presented based on optimal (OPF)model commercial solver. Based branch equation with re...

Allogeneic lymphocytes are potent mediators of leukemia and lymphoma remission. The goal of this study was to determine whether single MHC class I locus-mismatched lymphocytes could generate an antilymphoma activity in the absence of graft-versus-host-disease (GVHD) and to understand the underlying mechanisms. Immunoincompetent Scid or lethally irradiated mice were challenged i.v. with a lethal...

According to several classical results by Bézout, Sylvester, Cayley, and others, the classical discriminant Dn of degree n polynomials may be expressed as the determinant of a matrix whose entries are much simpler polynomials in the coefficients of f . However, all of the determinantal formulae for Dn appearing in the classical literature are equivalent in the sense that the cokernels of their ...

Serum pseudocholinesterase activity in pregnant women was assayed spectrophotometrically using either propionylthiocholine or suxamethonium as substrate. All patients had a normal phenotype as indicated by normal dibucaine and fluoride numbers. However, the mean cholinesterase activity was lower than in the general population. There was a negative correlation between cholinesterase activity and...

The MICs of several antibiotics (both hydrophobic and hydrophilic) which penetrate very poorly into intact Escherichia coli cells were found to be 2- to 10-fold decreased in the presence of low doses of various local anesthetics (procaine, dibucaine, tetracaine, chlorpromazine, and quinine). The concentrations of anesthetics necessary for this effect have no adverse effect on cell growth and ar...
