Štruktúra medzinárodných organizácií

Medzinárodné organizácie sa stávajú v súvislosti s globalizáciou čoraz častejšie aktérmi medzinárodných vzťahov. Rôznou mierou obmedzujú doposiaľ takmer neobmedzenú suverenitu štátov. Predstavitelia štátov postupne zistili, že niektoré problémy sa nedajú riešiť unilaterálne a preto pristúpili k vytvoreniu medzinárodných organizácií. Tieto rešpektujú záujmy členských štátov a snažia sa riešiť ich problémy, ktoré by za iných okolností boli nad rámec ich možností.medzinárodná organizácia, organizačná štruktúra, sídlo, rozpočet, výsady a imunity, uznesenia, riešenie medzinárodných problémov

Effect of particle size on functional and mechanical properties of single crystals of iron-based FeNiCoAlNb alloy

It is shown that [001]-single crystals Fe-28%Ni-17%Co-11.5%Al-2.5Nb (at. %) alloy aged at T=973 K, 1−20 hours are observed γ'-phase particle size of 3-25 nm, which give rise to thermoelastic of the γ-α′ martensitic transformation. The effect of size of γ'-phase particle on the critical stress of high temperature phase, the temperature range of superelasticity and the mechanical hysteresis are investigated

Bond formation at polycarbonate | X interfaces (X = Al2_2O3_3, TiO2_2, TiAlO2_2) studied by theory and experiments

Interfacial bond formation during sputter deposition of metal oxide thin films onto polycarbonate (PC) is investigated by ab initio molecular dynamics simulations and X-ray photoelectron spectroscopy (XPS) analysis of PC | X interfaces (X = Al$_2$O$_3$, TiO$_2$, TiAlO$_2$). Generally, the predicted bond formation is consistent with the experimental data. For all three interfaces, the majority of bonds identified by XPS are (C-O)-metal bonds, whereas C-metal bonds are the minority. Compared to the PC | Al$_2$O$_3$ interface, the PC | TiO$_2$ and PC | TiAlO$_2$ interfaces exhibit a reduction in the measured interfacial bond density by ~ 75 and ~ 65%, respectively. Multiplying the predicted bond strength with the corresponding experimentally determined interfacial bond density shows that Al$_2$O$_3$ exhibits the strongest interface with PC, while TiO$_2$ and TiAlO$_2$ exhibit ~ 70 and ~ 60% weaker interfaces, respectively. This can be understood by considering the complex interplay between the metal oxide composition, the bond strength as well as the population of bonds that are formed across the interface

Anthropogenic disturbance as a driver of microspatial and microhabitat segregation of cytotypes of Centaurea stoebe and cytotype interactions in secondary contact zones

Background and Aims In a mixed-ploidy population, strong frequency-dependent mating will lead to the elimination of the less common cytotype, unless prezygotic barriers enhance assortative mating. However, such barriers favouring cytotype coexistence have only rarely been explored. Here, an assessment is made of the mechanisms involved in formation of mixed-ploidy populations and coexistence of diploid plants and their closely related allotetraploid derivates from the Centaurea stoebe complex (Asteraceae). Methods An investigation was made of microspatial and microhabitat distribution, life-history and fitness traits, flowering phenology, genetic relatedness of cytotypes and intercytotype gene flow (cpDNA and microsatellites) in six mixed-ploidy populations in Central Europe. Key Results Diploids and tetraploids were genetically differentiated, thus corroborating the secondary origin of contact zones. The cytotypes were spatially segregated at all sites studied, with tetraploids colonizing preferentially drier and open microhabitats created by human-induced disturbances. Conversely, they were rare in more natural microsites and microsites with denser vegetation despite their superior persistence ability (polycarpic life cycle). The seed set of tetraploid plants was strongly influenced by their frequency in mixed-ploidy populations. Triploid hybrids originated from bidirectional hybridizations were extremely rare and almost completely sterile, indicating a strong postzygotic barrier between cytotypes. Conclusions The findings suggest that tetraploids are later immigrants into already established diploid populations and that anthropogenic activities creating open niches favouring propagule introductions were the major factor shaping the non-random distribution and habitat segregation of cytotypes at fine spatial scale. Establishment and spread of tetraploids was further facilitated by their superior persistence through the perennial life cycle. The results highlight the importance of non-adaptive spatio-temporal processes in explaining microhabitat and microspatial segregation of cytotype
