Thymidine was reacted in methanol with four epoxides of varying mutagenicities: propylene oxide, glycidol, epichlorohydrin and trichloropropylene oxide. A single product was detected with each epoxide, and these products had the same retention times on silica high pressure liquid chromatography (HPLC). UV spectra of the products identified them as 3-alkylthymidines, and this was confirmed by in...
Guang’ai Song and Yucai Su Department of Mathematics, Shanghai Jiao Tong University, Shanghai, 200240, China E-mail: [email protected], [email protected] Abstract. In a paper by Michaelis a class of infinite-dimensional Lie bialgebras containing the Virasoro algebra was presented. This type of Lie bialgebras was classified by Ng and Taft. In this paper, all Lie bialgebra structures on the Lie a...
Fits for the calculation of solvatochromic regression coefficients were done using the regression tool for the complexation of dioxovanadium(V) with iminodiacetic acid (IDA) and dissociation constants at T = 298 K and constant ionic strength of 0.1 mol dm-3 sodium perchlorate in different volume fractions of methanol (0 to 45 percent). A combination of potentiometric and UV spectrophotometric m...
Franklin H. North, "A New Profession for Women," Century Magazine, Nov. 18 82, p. 38. Almost one hundred years ago on January 1, 1889 the Cincinnati Training School for Nurses opened establishing a new profession for the women of Cincinnati. The impetus for the school did not arise from the hospital's medical staff or its trustees but instead from a group of prominent women in the city who, wit...
In this note, generalized connections σT,f are investigated, where AσT,fB = TAfT − A (B) for positive semidefinite matrix A and hermitian matrix B, and operator monotone function f : J → R on an interval J ⊂ R. Here the symbol T A denotes a reflexive generalized inverse of a positive bounded linear operator TA. The problem of estimating a given generalized connection by other ones is studied. T...
Solvent effects on the rates of some well-known nuclophilic substitution reactions have been analysed in terms of initial—state and transition-state contributions. Where possible, the latter have been further analysed by the method of model solutes, on which solvent effects on a transition state are compared to solvent effects on a solute that might be a suitable model for the transition state....
In situ activation of 3-arylpropiolic acids with T3P® (n-propylphosphonic acid anhydride) initiates a domino reaction furnishing 4-arylnaphtho[2,3-c]furan-1,3-diones in excellent yields. Upon employing these anhydrides as reactive intermediates blue-luminescent 4-aryl-1H-benzo[f]isoindole-1,3(2H)-diones are formed by consecutive pseudo three-component syntheses in a one-pot fashion. The Stokes ...
Abstract For a finite-dimensional Hopf algebra $\mathsf {A}$ , the McKay matrix {M}_{\mathsf {V}}$ of an -module {V}$ encodes relations for tensoring simple -modules with . We prove results about eigenvalues and right left (generalized) eigenvectors by relating them to characters. show how projective {Q}_{\mathsf obtained indecomposable modules is related dual module illustrate these Drinfeld d...
A number of 25 nitro-diphenylethers have been synthesized and assayed for their inhibitory activity in N-methylphenazonium-methosulfate mediated cyclic photophosphorylation. Their p/50-values were in the range from 3.5 to 5.3. A QSAR-analysis revealed that the lipophilicity of the nitro-diphenylethers as expressed by Z:t played a major role. In addition, the Taft steric parameter £ s in positio...
