A series of phenyl-substituted derivatives of 1,2-dimethyl-3,4-bis(hydroxymethyl)-5-phenylpyrrole bis(N-methylcarbamate) (1) were synthesized and tested for antileukemic activity against P388 lymphocytic leukemia in the mouse. All of the compounds tested, 1a--r, showed significant activity in this assay. Selected derivatives of 1 were tested against several… (More)
— Power system phasor time-domain simulation is often carried out through domain specific tools such as Eurostag, PSS/E, and others. While these tools are efficient, their individual sub-component models and solvers cannot be accessed by the users for modification. One of the main goals of the FP7 iTesla project  is to perform model validation, for… (More)
5'-O-Glucuronides of anticancer nucleosides, 5-fluorouridine and 5-fluorocytidine, were synthesized by three different methods. The best preparative procedure was the one starting from benzyl 5-O-(methyl 2', 3', 4'-tri-O-acetyl-beta-D-glucopyranosyluronate)-2,3-O-isopropylidene-beta-D-ribof uranoside (15) that was obtained almost quantitatively by… (More)
The activity of three pyrroles and four pyrrolizines is compared in several different experimental leukemias and solid tumors in mice. Two compounds were particularly noteworthy, the bis(N-cyclohexylcarbamate) and the bis[N-(2-propyl)] derivatives of 2,3-dihydro-5-(3,4-dichlorophenyl)-6,7-bis(hydroxymethyl)-1H-pyrrolizine. These two compounds showed a very… (More)
The infinite reduction of couplings is a tool to consistently renormalize a wide class of non-renormalizable theories with a reduced, eventually finite, set of independent couplings, and classify the non-renormalizable interactions. Several properties of the reduction of couplings, both in renormalizable and non-renormalizable theories, can be better… (More)
The author, Sister of Charity and Mother Superior of the Children's Home in Tarnów, describes the attitude of the authorities of the Polish People's Republic towards convent nursing in hospitals. The problem is exemplified by the situation of the Cracow Province of the Order of the Sisters of Charity. Apart from this main theme, Sister Mirosława Hałat says… (More)
2-Chloromethylbenzo[b]furans were prepared in high overall yield from the corresponding chloroethylphenyl ethers through chloroepoxide and alpha-chlorophenylacetone intermediates.
The syntheses for the bis(N-methylcarbamates) 3, 4a, 4b, and 5 are described. All four compounds were active in the in vivo P388 lymphocytic leukemia assay, with 3 being the most active.
We prove the renormalizability of various theories of classical gravity coupled with interacting quantum fields. The models contain vertices with dimensionalities greater than four, a finite number of matter operators and a finite or reduced number of independent couplings. An interesting class of models is obtained from ordinary power-counting… (More)
