Iron(II) sulfate release from drop-formed lipophilic matrices developed by special hot-melt technology.
Iron(II) sulfate-containing lipophilic matrices were developed by a special hot-melt technology (melt solidification in drops), using stearin, white wax and their mixture as conventional bed materials. The special technology resulted in spherical particles which can be filled directly into capsules; these store iron as a depot and ensure a slow and uniform release, whereby the irritation of the...
متن کاملOn Some Special Classes of Sonnenschein Matrices
In this paper we consider the special classes of Sonnenschein matrices, namely the Karamata matrices $K[alpha,beta]=left(a_{n,k}right)$ with the entries [{a_{n,k}} = sumlimits_{v = 0}^k {left( begin{array}{l} n\ v end{array} right){{left( {1 - alpha - beta } right)}^v}{alpha ^{n - v}}left( begin{array}{l} n + k - v - 1\ ,,,,,,,,,,k...
متن کاملPosition papers by EADPH special interest groups.
The board of the European Association for Dental Public Health (EADPH) is very grateful that two of the EADPH special interest groups were able to produce position papers in their fields within a relatively short time. Their first article, “Methodological issues in epidemiological studies of periodontitis – how can it be improved,” was prepared by Roos Leroy, Ken Eaton and Amir Savage following...

متن کاملA brief introduction to quaternion matrices and linear algebra and on bounded groups of quaternion matrices
The division algebra of real quaternions, as the only noncommutative normed division real algebra up to isomorphism of normed algebras, is of great importance. In this note, first we present a brief introduction to quaternion matrices and quaternion linear algebra. This, among other things, will help us present the counterpart of a theorem of Herman Auerbach in the setting of quaternions. More ...
