in atom transfer radical polymerization (atrp) of methyl acrylate (ma) with polyvinyl acetate macroinitiator in bulk at 90°c the plots of ln [m]0/[m] increased linearly with reaction time. the apparent propagation rate constant (kp app) of the reaction was obtained from the linear curve and used to calculate the free macroradical concentration ([r°]) in polymerization medium. the [r°] and also ...

radiation degradation of chitosan is one of the most important methods to prepare antibacterial oligochitosans. in this study, the effect of solvent on the reduction of degradation dose and enhancement of the antibacterialactivity of chitosan against pectobacterium carotovorum (pc) has been considered.gamma radiation degradation was applied to chitosan as solid and aqueous solution at dose rang...

background: this study was designed to examine a unique and low dose use of intravenous enoxaparin in elective percutaneous coronary intervention (pci) that would be applicable to an unselected population regardless of age, weight, and renal function. there is limited experience in anticoagulation using intravenous low-molecular-weight heparin in pci. methods: a total of 100 consecutive patient...

Consider the family tree T of a branching process starting from a single progenitor and conditioned to have v=v(T) edges (total progeny). To each e d g e ( e ) we associate a weight W(e). The weights are i.i.d, random variables and independent of T. The weighted height of a self-avoiding path in T starting at the root is the sum of the weights associated with the path. We are interested in the ...

A common method of constructing f-error correcting/all unidirectional error detecting (t-ECIAUED) codes is to choose a t E C code and then to append a tail such that the new code can detect all unidirectional errors. The tail is a function of the weight of the codeword. We present a technique to reduce the weight distribution of the CEC code so that the tail needed will be shorter in some cases...

To evaluate the effect of diffusion on the pulmonary extravascular water volume determined from indicator dilution studies, simultaneous comparisons of the pulmonary extravascular distribution volumes of tritiated water (THO) and of three lipid soluble substances with higher molecular weights were made. In 21 studies on pentobarbital-anesthetized dogs, the distribution volume of antipyrine (AP)...

Antidepressants, especially amitriptyline, are among themost frequent drug classes involved in intoxications. Despite its small molecular weight, amitriptyline is not considered to be eliminated by extracorporeal treatmentmethods due to its high protein binding and large volume of distribution. New high cut-off dialysers have so far not been used for removal of amitriptyline. We report two case...

Indium trichloride, benzyl alcohol, and triethylamine (without an added 'directing' multidentate ligand) generate a catalyst in situ for the room temperature polymerization of D,L-lactide affording highly heterotactic polylactide of controlled molecular weight and narrow molecular weight distribution.
