Prvi nalaz kritično ugrožene vrste leptira Maculinea alcon (Denis & Schiffermüller, 1775) (Lepidoptera: Lycaenidae) u panonskom dijelu Hrvatske
The critically endangered butterfly Maculinea alcon was found at the locality Grubišnopoljska Bilogora in August 2006. That is the first finding of this species in the Pannonian part of Croatia and the second in Croatia as a whole. The biology of this critically endangered species is discussed, as well as some aspects of ecology and protection measures.Kritično ugrožena vrsta leptira Maculinea alcon pronađena je u kolovozu 2006. godine na lokalitetu Grubišnopoljska Bilogora. To je prvi nalaz ove vrste na prostoru panonske regije Hrvatske, odnosno drugi za Hrvatsku. U radu se raspravlja o biologiji vrste, nekim aspektima ekologije kao i potrebnim mjerama zaštite ovog kritično ugroženog leptira u fauni Hrvatske
Control over phase separation and nucleation using a laser-tweezing potential
Control over the nucleation of new phases is highly desirable but elusive. Even though there is a long history of crystallization engineering by varying physicochemical parameters, controlling which polymorph crystallizes or whether a molecule crystallizes or forms an amorphous precipitate is still a poorly understood practice. Although there are now numerous examples of control using laser-induced nucleation, the absence of physical understanding is preventing progress. Here we show that the proximity of a liquid–liquid critical point or the corresponding binodal line can be used by a laser-tweezing potential to induce concentration gradients. A simple theoretical model shows that the stored electromagnetic energy of the laser beam produces a free-energy potential that forces phase separation or triggers the nucleation of a new phase. Experiments in a liquid mixture using a low-power laser diode confirm the effect. Phase separation and nucleation using a laser-tweezing potential explains the physics behind non-photochemical laser-induced nucleation and suggests new ways of manipulating matter
Potential Energy Surface Reconstruction and Lifetime Determination of Molecular Double-Core-Hole States in the Hard X-Ray Regime
A combination of resonant inelastic x-ray scattering and resonant Auger
spectroscopy provides complementary information on the dynamic response of
resonantly excited molecules. This is exemplified for CH3I, for which we
reconstruct the potential energy surface of the dissociative I 3d−2 double-
core-hole state and determine its lifetime. The proposed method holds a strong
potential for monitoring the hard x-ray induced electron and nuclear dynamic
response of core-excited molecules containing heavy elements, where ab initio
calculations of potential energy surfaces and lifetimes remain challenging
Experiences in olive oil purity and quality assessment as a tool for pumpkin seed oil evaluation. What can consumers benefit?
Olive and pumpkin seed oils play a specific role in Slovenian edible oil market. That is why exact and accurate tools for assessing the oils’ quality and purity (adulteration) are needed. One of the tools is registering certain names and foodstuffs in National registers and the Register of European Union. Another tool is the analysis which can help to assess the characteristics of the oil and to classify it in categories. In the field of olive oils, this has been done excellently with the European Commission regulations. In the present work we tried to test few pumpkin seed oils for fatty acids content, trans isomers of fatty acids, composition of sterols and tocopherols. The main goal was to check the purity of the oils and understand the present situation in the field. The analytical results show that some samples are adulterated with seed oils. What can consumers benefit? From the Slovenian olive oil experience it can be concluded that the path towards better quality oils does not strictly follow analytical methods but tries to track well-established rules and definitions of quality and purity. The consumers must learn and be aware that the quality and purity can be analytically proven
Backward FDI linkages as a channel for transferring technology and building innovation capability: The case of Slovenia
Backward linkages of foreign subsidiaries with their local suppliers prove to be one of the main channels of knowledge spillovers via foreign direct investment. This paper analyses the potential of backward linkages of foreign subsidiaries in Slovenia for the transfer of technology and for the innovation capability-building of their local suppliers. Based on a survey of foreign subsidiaries in Slovenia, we aim to investigate the mechanisms of knowledge spillovers via linkages of foreign subsidiaries with local suppliers in Slovenia. This enables us to trace the development of the technological and organizational capability of local suppliers in order to meet the growing demands made by foreign subsidiaries. This firm-level analysis is complemented with an analysis of the national innovation policy to see whether the measures introduced to support innovation are in fact helping local business to improve its technological capability and are thus providing additional stimuli for innovation.Les effets de liaison amont entre les filiales étrangères et les fournisseurs locaux s'avèrent être les principaux vecteurs de transferts de connaissances via les IDE. L'article analyse les effets potentiels de liaison amont de filiales étrangères en Slovénie, en ce qui concerne les transferts de technologie au regard de la construction de capacités d'innovation de leurs fournisseurs locaux. A partir d'une enquête auprès de filiales étrangères en Slovénie, nous étudions les mécanismes de transferts de connaissances à travers les effets de liaison avec les fournisseurs locaux en Slovénie. Ce qui nous permet de suivre le développement des capacités technologiques et organisationnelles des fournisseurs locaux, dans le but de satisfaire les exigences croissantes des filiales étrangères. L'analyse au niveau de la firme est complétée par une analyse de la politique nationale d'innovation afin de vérifier si les mesures destinées à promouvoir l'innovation aident réellement les entreprises locales à améliorer leurs capacités technologiques et si elles constituent, par conséquent, une incitation supplémentaire à l'innovation.European Journal of Development Research (2009) 21, 137–153. doi:10.1057/ejdr.2008.11

Exercise-induced effects on a gym atmosphere
We report results of analysis of a month-long measurement of indoor air and environment quality parameters in one gym during sporting activities such as football, basketball, volleyball, badminton, boxing, and fitness. We have determined an average single person's contribution to the increase of temperature, humidity, and dust concentration in the gym air volume of 12500 m3: during 90-min exercise performed at an average heart rate of 143 ± 10 bpm, a single person evaporated 0.94 kg of water into the air by sweating, contributed 0.03 K to the air temperature rise and added 1.5 μg/m3 and 5 ng/m3 to the indoor concentration of inhalable particles (PM10) and Ca concentration, respectively. As the breathing at the observed exercise intensity was about three times faster with respect to the resting condition and as the exercise-induced PM10 concentration was about two times larger than outdoors, a sportsman in the gym would receive about a sixfold higher dose of PM10 inside than he/she would have received at rest outside.Fil: Žitnik, M..

Shaping the Balkan corridor: Development and changes in the migration route 2015–16
In 2015–16, Europe witnessed the biggest refugee crisis since the Second World War. Over a million people moved via different migration routes. The key route was the Balkan corridor running from Turkey, via Greece, to Central, Western and Northern Europe. The aim of this paper is to describe the development and changes in the route and provide an analysis of transit via Balkan countries, looking at factors that influenced the shape of the corridor. This refugee crisis was challenging for European countries and the whole European Union (EU). This corridor was unique, being de facto formalized semi‐legal territory, which the EU had never faced before. An official reaction to the crisis was necessary due to the substantial number of people who were on the move, seeking to cross the Balkan countries in the fastest manner possible. Therefore, the response was focused on arranging transport and providing only short‐term accommodation. This paper uses the PESTLE framework to examine the key political, economic, social, technological, legal and environmental aspects that influenced the Balkan corridor, as well as changes in the route over time and responses to them. The role of the media in shaping the corridor is also acknowledged, thus resulting in a PESTLE‐M framework. Findings from the research are important, as it is likely that the EU will face a similar crisis in the near future. Therefore, there is a need to prepare and develop a plan in case such a situation arises.peerReviewe
