We use B. Randol’s method to improve the error term in the prime geodesic theorem for a noncompact Riemann surface having at least one cusp. The case considered is a general one, corresponding to a Fuchsian group of the first kind and a multiplier system with a weight on it.

: Turopolje pig (TP) is a native Croatian breed, created during the early middle ages in Turopolje region in Central Croatia. It is a medium-sized, primitive, fatty-type breed. Due to their modest rearing requirements, its resistance and good adaptation to local marsh meadows and oak forests, the TP breed has been an important food source for the local population for centuries. However, the rapid penetration of imported lean pigs in the second half of the 20th century, as well as the ban of forest grazing, significantly reduced the interest in this breed. The result was a drastic decrease in the population size. Currently, despite the state support, TP breed is still endangered, with a population of only 132 sows and 30 boars kept in 16 farms. Hence, a new strategy is needed for renewing the TP breed, based on purebred animals, which should be preserved as a resource for local livestock production and sustainable development. Unfortunately, few recent data on the morphological and reproductive traits of TP are available. The aim of this study, therefore, was to determine these traits on TP breeding sows (n=40) reared in a traditional outdoor system on a farm with the largest single herd of TP. The mean (±st. dev.) age (months) and body weight (kg) of sows were 67.5±26.0 and 96.6±18.4, respectively. Height at withers and rumps, chest girth, body, head, ear and tail lengths were 65.2±2.8, 68.4±2.9, 111.2±10.4, 126.0±5.2, 27.0±0.90, 22.5±8.3 and 29.9±2.01 cm, respectively. The average number of piglets born alive was 4.47±1.96, of which 3.08±2.17 were weaned. The age at first farrowing was 22.1±7.9 months. Data were collected within H2020 project TREASURE *.

Fiber tractography based on non-invasive diffusion imaging is at the heart of connectivity studies of the human brain. To date, the approach has not been systematically validated in ground truth studies. Based on a simulated human brain dataset with ground truth white matter tracts, we organized an open international tractography challenge, which resulted in 96 distinct submissions from 20 research groups. While most state-of-the-art algorithms reconstructed 90% of ground truth bundles to at least some extent, on average they produced four times more invalid than valid bundles. About half of the invalid bundles occurred systematically in the majority of submissions. Our results demonstrate fundamental ambiguities inherent to tract reconstruction methods based on diffusion orientation information, with critical consequences for the approach of diffusion tractography in particular and human connectivity studies in general.

Lukavac, as many other Bosnian and Herzegovinian industrial cities, especially in the winter period, has deteriorated air quality and the greatest polluters are industry, individual heating and transportation. Considering that Lukavac is situated in the valley in which numerous industrial facilities are installed, in the periods of unfavorable weather conditions the town and its surroundings are naturally predisposed for additional air pollution. In this paper we analyze the possibility to form bioparks, which would have positive impacts on the ecological and economic conditions in Lukavac and similar environments. To establish the bioparks, the degraded and abandoned land surfaces, caused by soil erosion or the surface exploitation of mineral resources, could be used. These are located at numerous locations and cover large areas, both in Lukavac and in other industrial areas in Bosnia and Herzegovina. This paper presents the basic biological characteristics of paulownia and possibilities of planting this tree in areas that are now unused, in the space which is characterized by extreme pollution of atmospheric complex. The selected method is bioremediation, and in this case it is the planting of biological material or woody plant species Paulownija elongata. In this way the degraded surfaces would get the function of biological parks, that is, they would become "oxygen producer" surfaces, and absorbers of CO2 which is emitted from industrial plants. This species has rapid growth and development of biomass, so the bioparks could be used to serve as the surfaces for alternative fuel with minimal amounts of sulfur, and also as eco - educational parks.

Negative attitudes toward homosexuals are just one of many that are often expressed toward various minority groups. There are numerous determinants of negative attitudes towards stigmatized groups, and personality traits are certainly one of them. Therefore, the purpose of this study was to examine the relationship between the Big Five personality traits, authoritarianism and attitudes against homosexuals. The study included 583 students (443 female and 139 male) of different universities in the Republic of Croatia, with an average age of 21 years. Participants were asked to complete a questionnaire that examined the Big Five personality traits, an Authoritarianism scale and also a Scale of attitudes toward homosexuals. The results show a significant negative correlation of openness to experience and negative attitudes towards homosexuals and a positive one between conscientiousness and authoritarianism and the negative attitudes. Also, authoritarianism is a mediating variable in the relationship between openness and conscientiousness and attitudes toward homosexuals. The obtained results are discussed in the context of existing models and research results.
