279 bat specimens of 14 species were examined for ectoparasites during the autumnal swarming period in different cave roosts in Albania. A total of 550 ectoparasites were identified belonging to 19 species. The structure of the ectoparasite fauna and the influence of body mass index and body surface area on the parasite load were discussed for the most common bat species (Miniopterus schreibersii, Myotis myotis, M. capaccinii and Rhinolophus ferrumequinum). The ectoparasite fauna of the studied bats in Albania is qualitatively similar to northern Bulgaria (SCHEFFLER, 2011). The bat species Myotis myotis and M. daubentonii are infested with different ectoparasites in the Balkan region during the autumn swarming period than specimens of the same bat species in Central Europe. There is a strong need of further research for most host and ectoparasite species in the entire Balkan region.

A water soluble fluorescent polymer as a dual colour sensor for temperature and a specific protein
(2013)
We present two thermoresponsive water soluble copolymers prepared via free radical statistical copolymerization of N-isopropylacrylamide (NIPAm) and of oligo(ethylene glycol) methacrylates (OEGMAs), respectively, with a solvatochromic 7-(diethylamino)-3-carboxy-coumarin (DEAC)-functionalized monomer. In aqueous solutions, the NIPAm-based copolymer exhibits characteristic changes in its fluorescence profile in response to a change in solution temperature as well as to the presence of a specific protein, namely an anti-DEAC antibody. This polymer emits only weakly at low temperatures, but exhibits a marked fluorescence enhancement accompanied by a change in its emission colour when heated above its cloud point. Such drastic changes in the fluorescence and absorbance spectra are observed also upon injection of the anti-DEAC antibody, attributed to the specific binding of the antibody to DEAC moieties. Importantly, protein binding occurs exclusively when the polymer is in the well hydrated state below the cloud point, enabling a temperature control on the molecular recognition event. On the other hand, heating of the polymer-antibody complexes releases a fraction of the bound antibody. In the presence of the DEAC-functionalized monomer in this mixture, the released antibody competitively binds to the monomer and the antibody-free chains of the polymer undergo a more effective collapse and inter-aggregation. In contrast, the emission properties of the OEGMA-based analogous copolymer are rather insensitive to the thermally induced phase transition or to antibody binding. These opposite behaviours underline the need for a carefully tailored molecular design of responsive polymers aimed at specific applications, such as biosensing.
How can I lie if I am telling the truth? The unbearable lightness of being of strong and weak modals, modal adverbs and modal particles in discourse between epistemic modality and evidentiality Peter Kosta The major part of my contribution will concentrate on the close relation between epistemic modality and evidentiality and the notions of truth value, indirect speech acts and conversational implicature (cf. Kosta 2005; Kosta 2011b). It is well attested in the literature that the epistemic modal adverb Russian o;evidno, Czech o;ividn;, German offensichtlich, Italian ovviamente can have different interpretation depending on the conversation situation, truth values and scope relations (cf. Kosta 2011a; von Fintel and Gillies 2010; Kratzer 2010). Even a bona fide "epistemicö modal can have two interpretations: a 'strong' interpretation, which - at least with necessity modals - commits the speaker to the truth of the proposition the modal scopes over (von Fintel and Gillies 2010), and a 'weak' interpretation, which is relativized to the content of some source of information that may or may not be faithful to reality. In order to be able to decide whether epistemic particles and modals are strong or weak we have to differentiate between different sources of conversational backgrounds. Following the findings in the research of notional category of modals in Kratzer (2010), the proposed analysis of modals allows for one modal parameter to be fixed by the context of use. It implies that that parameter is responsible for the variety of interpretations modals can receive.

Derivatization of fullerene (C60) with branched aliphatic chains softens C60-based materials and enables the formation of thermotropic liquid crystals and room temperature nonvolatile liquids. This work demonstrates that by carefully tuning parameters such as type, number and substituent position of the branched chains, liquid crystalline C60 materials with mesophase temperatures suited for photovoltaic cell fabrication and room temperature nonvolatile liquid fullerenes with tunable viscosity can be obtained. In particular, compound 1, with branched chains, exhibits a smectic liquid crystalline phase extending from 84°C to room temperature. Analysis of bulk heterojunction (BHJ) organic solar cells with a ca. 100 nm active layer of compound 1 and poly(3-hexylthiophene) (P3HT) as an electron acceptor and an electron donor, respectively, reveals an improved performance (power conversion efficiency, PCE: 1.6 ñ 0.1%) in comparison with another compound, 10 (PCE: 0.5 ñ 0.1%). The latter, in contrast to 1, carries linear aliphatic chains and thus forms a highly ordered solid lamellar phase at room temperature. The solar cell performance of 1 blended with P3HT approaches that of PCBM/P3HT for the same active layer thickness. This indicates that C60 derivatives bearing branched tails are a promising class of electron acceptors in soft (flexible) photovoltaic devices.
