Das Flüchtlingsproblem in ausgewählten Pressediskursen - gleich oder ungleich?
2020
This article presents the results of the analysis of three sets of texts concerning the issue of refugees in various periods of history. Their subject matter concerns Eastern refugees from the former German territories, the so-called refugees from GDR (East Germany) and modern international refugees. The purpose of this article is to find answers to the following questions: 1. How is the refugee problem linguistically expressed in the selected collection of texts? 2. What characteristics do newspapers give to refugees and how are they judged? 3. What differences and similarities can be observed in the description of the issues concerning refugees based on the selected collections of texts?

New Bioprecursor Prodrugs of Sulfadiazine: Synthesis, X-ray Structure and Hirshfeld Analysis
2022
Sulphonamide motif is found extensively in numerous chemotherapeutic drug candidates, it acts by stopping the production of folate inside the bacterial cell. Current research has established the synthesis and characterization of new bioprecursor prodrugs of sulfadiazine. The first prodrug, 3, was synthesized via the coupling of diazonium salt of sulfadiazine with ethyl acetoacetate in AcONa at 0 °C. The second prodrug, sulfadiazine-pyrazole, 5, was furnished via cyclocondensation of the hydrazono derivative, 3, and 2-pyridyl hydrazine, 4. The generated data from the X-ray analysis is interpreted and refined to obtain the crystal structure of the target compound, 5. Density functional th…
Synthesis, X-ray Crystal Structure and Antimicrobial Activity of Unexpected Trinuclear Cu(II) Complex from s-Triazine-Based Di-Compartmental Ligand v…
2019
The synthesis and X-ray crystal structure of the trinuclear [Cu3(HL)(Cl)2(NO3)(H2O)5](NO3)2 complex of the s-triazine-based di-compartmental ligand, 2-methoxy-4,6-bis(2-(pyridin-2-ylmsethylene)hydrazinyl)-1,3,5-triazine (H2L), are presented. The Cu1 and Cu2 are penta-coordinated with CuN3ClO coordination environment, distorted square pyramidal coordination geometry while Cu3 is hexa-coordinated with CuN2O4 coordination sphere, and distorted octahedral geometry. The complex crystallized in the primitive P-1 triclinic crystal system with two molecular units per unit cell. Its packing is dominated by the O–H (35.5%) and Cl–H (8.8%) hydrogen bonding interactions as well as the π–π stacking (2.3…
Self-assembly of new cobalt complexes based on [Co(SCN)4], synthesis, empirical, antioxidant activity, and quantum theory investigations
2022
The cobalt (II) complexes have been synthesized from the reaction of the cationic entities (3,4-dimethylaniline (1) and histamine (2)) with metallic salt CoCl2⋅6H2O and thiocyanate ion (SCN−) as a ligand in H2O/ethanolic solution and processing by the evaporation crystal growth method at room temperature to get crystals. The synthesized complex has been fully characterized by single-crystal X-ray diffraction. UV–Visible, FTIR spectroscopy, TGA analysis, and DFT circulations were also performed. The crystal structural analysis reveals that the solid (1) {[Co(SCN)4] (C8H12N)3}·Cl crystallizes in the monoclinic system with the space group P21/n and the solid (2) {[Co(SCN)4](C5H11N3)2}·2Cl crys…
Synthesis, characterization, crystal structures and biological screening of 4-amino quinazoline sulfonamide derivatives
2019
Three quinazolin-4-ylamino derivatives containing phenylbenzenesulfonamides (7a-7c) were synthesized by reacting (E)-N'-(2-cyanophenyl)-N,N-dimethyl formamidine (6) with different 4- amino-N-(phenyl)benzenesulfonamides (4a-4c) and characterized by different techniques such as HRMS, IR, 1H NMR and 13C NMR spectroscopy. The structural properties were further examined by single crystal X-ray diffraction method. The X-ray data shows that compounds 7a and 7c contain two molecules and 7b contains one molecule in the asymmetric unit. Comparison of conformation of two distinct molecules, “A” and “B”, in the asymmetric unit of 7a and 7c were studied with the aid of reported literature. The in vitro …
Educación compensatoria : efectos recientes de un estudio clásico (High-Scope)
2014
Este artículo analiza dos estudios que prueban la tesis de que la educación de los desfavorecidos sociales en la edad temprana -3 y 4 años- merece la pena a corto y largo plazo. Para ello se analizan dos estudios preescolares complementarios –Perry y Curriculum -, de la Fundación High/Scope en los 60, evaluados en diversos momentos intermedios, el primero hasta alcanzar los 40 años y el segundo 23. Se describen los estudios y programas educativos, se analizan cuestiones metodológicas ligadas al seguimiento (muestra, validez, variables), se muestran los hallazgos, los tempranos específicamente escolares y otros de naturaleza distinta en la edad adulta. Finalmente se discute la modificabilida…
Polâki v Krimu u 20-30 roki XX stolìttâ
2015
During the last few years Europe is heading the problem of refugees. Nowadays there are 125 ethnicities in Crimea. Poles constitute one of these groups, and it is not the smallest one. A part of the contemporary community of Crimean Poles are the descendants of Polish refugees, who came to the peninsula in the first half of the 20th century. The present article is based on an analysis of the data from Crimean archives referring to the given topic. Published materials may arise the interest of not only historians but can be also useful for people willing to re-establish family ties, as well as in the process of solving problems connected with the refugees, whose number in the contemporary wo…
