Abstract: Obe besedili sta nastali v prelomnih trenutkih slovenske zgodovine: Prešernova pesnitev v času nemške politične, gospodarske in kulturne nadvlade in porajanja zahtev po združeni Sloveniji, Bevkova povest pa v času italijanskega fašizma in okupacije Primorske. Na prvi pogled Prešernova visoka romantična poezija in Bevkova prejkone trivialna povest razen tematike poganstva in krščanstva nimata nič skupnega, vendar pa gre v obeh primerih za prikrito sporočilo, pogojeno s cenzurnimi postopki tedanje oblasti, za obsodbo nasilnih tujih oblastnikov, za pozive k narodni enotnosti, za poudarjanje domoljubne zavesti in za odnos do narave, ki kot najvišjo vrednoto vzpostavlja tostranstvo in ne onostranstvo. Pričujoča primerjava in interpretacija pa vidi v Bevkovi povesti tudi neposredno navezavo na Prešernovo pesnitev, in sicer kot njeno tematsko nadaljevanje, časovno prilagoditev in razlago.

Abstract: The paper reviews recent advances in characterisation of charge carrier transport in organic semiconductor layers by time-of-flight photocurrent measurements, with the emphasis on the measurements of the samples with co-planar electrodes. These samples comprised an organic semiconductor layer whose thickness is on the order of a μm or less, and thus mimic the structures of organic thin film transistors. In the review we emphasise the importance of considering spatial variation of electric field in these, essentially two-dimensional structures, in interpretation of photocurrent transients. We review the experimental details of this type of measurements and give examples that demonstrate exceptional sensitivity of the method to minute concentration of electrically active defects in the organic semiconductors as well as the capability of probing charge transport along the channels of different mobility that reside in the same sample.

Abstract: During the past decade the experimental studies of biopolymer conformations have reached an unprecedented level of detailization and allow to study single molecules in vivo [1]. Processing of experimental data essentially relies on theoretical approaches to conformational transitions in biopolymers [2]. However, the models that are currently used, originate from the early 1960's and contain several unjustified assumptions, widely accepted at that time. Thus, the view on the conformational transitions in the polypeptides as a two-state process has very limited applicability because the all-or-none transition mechanism takes place only in short polypeptides with sizes comparable to the spatial correlation length; the original formulation of Zimm-Bragg model is phenomenological and does not allow for a microscopic model for water; the implicit consideration of the water-polypeptide interactions through the ansatz about the quadratic dependence of free energy difference on temperature can only be justified through the assumption of an ideal gas with a constant heat capacity. To get rid of these deficiencies, we augment the Hamiltonian formulation [3] of the Zimm-Bragg model [4] with the term describing the water-polypeptide interactions [5]. The analytical solution of the model results in a formula, ready to be fit to Circular Dichroism (CD) data for both heat and cold denaturation. On the example of several sets of experimental data we show, that our formula results in a significantly better fit, as compared to the existing approaches. Moreover, the application of our procedure allows to compare the strengths of inter- and intra-molecular H-bonds, an information, inaccessible before. References [1] I. König, A. Zarrine-Afsar, M.
