Der griechische Gelehrte Georgios Zachariadis und sein Beitrag zum slawischen Schrifttum im 19. Jahrhundert
No full textAmong the Greek scholars who lived during the 19th century in the north-eastern Balkans, and also in Central Europe, and by their work contributed to the spiritual development of the Balkan Slavs, pride of place must be given to Georgios Zachariadis. Unfortunately, however, no detailed monograph on Zachariadis exists. On this account the problems that arise concerning the life and activities of this Greek scholar are still many and varied. In his study the author tries to fill one part of this lacuna. At the beginning of the work the following are examined, on the basis of new historical evidence: the date and place of Georgios Zachariadis’ birth, his studies and tenure as teacher in the Greek school at Zemun, the Serbian school at Šabac, and the Greek school in Vienna. The author continues his study by analyzing the various works of Zachariadis, which are written on Old Church^Slavonic, and the translations this Greek scholar made from Greek into Old Church Slavonic. Finally, the extent of Georgios Zachariadis’ contribution to Slavonic letters is made clear

Limiting case of an isoperimetric inequality with radial density and applications
No full textWe prove a sharp isoperimetric inequality with radial density whose functional counterpart corresponds to a limiting case for the exponents of the Il'in (or Caffarelli-Kohn-Nirenberg) inequality in L 1. We show how the latter applies to obtain an optimal critical Sobolev weighted norm improvement to one of the L 1 weighted Hardy inequalities of [25]. Further applications include an L p version with the best constant of the functional analogue of this isoperimetric inequality and also a weighted Pólya-Szegö inequality

The evaluation of the effect of PAMAM dendrimers in the solubility of lmiquimod
No full textCharles University, Faculty of Pharmacy in Hradec Králové Department of Pharmaceutical Technology Supervisor: Dr. Georgios Paraskevopoulos, Ph.D. Consultant: Eleni Panoutsopoulou Author: Mgr. Thu Thao Truongová Title of the thesis: The evaluation of the effect of PAMAM dendrimers in the solubility of Imiquimod Dendrimers are highly branched polymeric compounds with defined properties. They are used as a nanoparticle delivery system, however concurrently they have significant potential in enhancing the solubility of poorly water soluble drugs. Dendrimers work as drug carriers either by encapsulating the drug in their branched internal structure or they create interactions with the drug in the outer layer via terminal functional groups. The aim of this work was to evaluate the effect of polyamidoamine (PAMAM) dendrimers on the solubility of the hydrophobic drug imiquimod. Solutions of zero, first, second and third generation dendrimers were prepared at six different concentrations. During the experiment, the pH of the solutions was measured before and after addition of excess amount of imiquimod. Subsequently, analysis was performed by high-performance liquid chromatography. The measured results show that the first generation of PAMAM dendrimers is able to increase the solubility of imiquimod in...C2-Internal Abstrakt Univerzita Karlova, Farmaceutická fakulta v Hradci Králové Katedra Farmaceutické technologie Školitel: Dr. Georgios Paraskevopoulos, Ph.D. Konzultant: Eleni Panoutsopoulou Autor: Mgr. Thu Thao Truongová Název rigorózní práce: Hodnocení účinku PAMAM dendrimerů na rozpustnost imiquimodu Dendrimery jsou velmi rozvětvené polymerické sloučeniny s definovanými vlastnostmi. Používají se jako nanočásticový distribuční systém, zároveň však mají významný potenciál v oblasti zvyšování rozpustnosti ve vodě špatně rozpustných léčiv. Dendrimery fungují jako nosiče léčiva buď na principu enkapsulace molekuly léčiva ve své rozvětvené vnitřní struktuře nebo vytvářejí interakce s léčivem ve vnější vrstvě skrze terminální funkční skupiny. Cílem této práce bylo zhodnotit účinek polyamidoaminových (PAMAM) dendrimerů na rozpustnost hydrofobního léčiva imiquimod. Postupně byly připraveny roztoky dendrimerů nulté, první, druhé a třetí generace v šesti různých koncentracích. Během experimentu se měřilo pH roztoků před a po přidání nadbytečného množství imiquimodu. Následně byla provedena analýza vysokoúčinnou kapalinovou chromatografií. Z naměřených výsledků použitých generací PAMAM dendrimerů vyplývá, že první generace těchto dendrimerů dokázala nejvíce zvýšit rozpustnost imiquimodu ve vodném prostředí.
