The redesigned Extensible Simulation Package for Research on Soft matter systems (ESPResSo++) is a free, open-source, parallelized, object-oriented simulation package designed to perform many-particle simulations, principally molecular dynamics and Monte Carlo, of condensed soft matter systems. In addition to the standard simulation methods found in(More)
Herein we report on the influence of salt and polyelectrolyte (PEL) concentration, molecular weight, and mixing ratio on the size and size distribution of polyelectrolyte complex (PEC) particles composed of cationic poly(diallyldimethylammonium chloride) and anionic poly(styrene sulfonic acid). The unusual salt concentration dependence of PEC particle sizes(More)
Continuing a study of the alkaloid composition of i~alictrum baicalense [i], we have investigated the epigeal part of ~. baicalense Turcz., collected on June 26, 1978, in the environs of the village of Ignashino, Skovorodino region, Amur province. By the usual method, 0.54% of total bases was obtained, and these were separated into phenolic and nonphenolic(More)
We have previously reported on the isolation from the epigeal part of Thalictrum baicalense Turcz. of the new aporphine alkaloids baicaline [i] and baicalidine [2]. We now give the results of a further study of the alkaloid composition of Th. baicalense. The phenolic fraction of the combined bases [2] was chromatographed on a column of silica gel. The(More)
We have investigated the alkaloid composition of the stems of Thalictrum baicalense Turcz., collected on June 25, 1982 in the Skovorodino region of the Amur province. When a concentrated chloroform extract was treated with 10% sulfuric acid, berberine sulfate (I) (0.043% on the weight of the air-dry stems) was obtained. The filtrate after the separation of(More)
UNLABELLED Spine disorders are a highly relevant problem in neurosurgical pathology. The development of diagnostic imaging methods makes it possible to perform intraoperative computed tomography. A special intraoperative cone beam computed tomography scanner "O-arm" has been designed; it combines a function of a C-arm machine and computer tomography(More)
