The fauna of hoverflies (Diptera: Syrphidae) of Vojvodina province, Serbia

Many hoverfly species of faunal and zoogeographical interest are found in Serbia's northern province of Vojvodina due to the diversity of its biotopes. In this paper, the presence of 252 species of hoverflies (Diptera: Syrphidae) from 69 genera is documented. Five species are here recorded for the first time in Serbia: Anasimyia contracta Claussen & Torp Pedersen, 1980; Anasimyia transfuga (Linnaeus, 1758); Eristalinus megacephalus (Rossi, 1794); Helophilus hybridus Loew, 1846; and Mallota fuciformis (Fabricius, 1794). One species is recorded for the first time in Vojvodina: Cheilosia brunnipennis (Becker, 1894). The records of 12 species from Vojvodina Province are the only ones on the Balkan Peninsula, while the records of 15 species are the only ones in Serbia

Linkage disequlibrium in populations of Merodon avidus A. (Diptera, Syrphidae)

Analysis of the genetic structure in the populations of Merodon avidus A originated from the Dubašnica Mountain, Serbia (AADUB), Pindos Mountain Greece (AAPIN) and Morinj, Montenegro (AAMOR) was done. Based on the polyacrylamide gel electrophoresis out of 16 analyzed loci 10 izozymic loci were monomorphic: Aat, Fum, Hk-2, Hk-3, Idh-2, Mdh-1, Pgm, Sod-1, Sod-2 Sod-3. Nonrandom association between alleles of the Ao and Me in the AAMOR population has been registered. Significant association among alleles of the Ao and Mdh-2 loci in AADUB and Ao and Gpd-2 loci in AAPIN was found as well. Percent of the locus with observed significant gametic disequilibrium was from 16.7% in AAMOR to significant association of the only variable loci pair in AADUB and AAPIN

Assessment of plastic flows and stocks in Serbia using material flow analysis

Material flow analysis was used to assess the amounts of plastic materials flows and stocks that are annually produced, consumed, imported, exported, collected, recycled, and disposed in the landfills in Serbia. The analysis revealed that approximately 269,000 tons of plastic materials are directly disposed in uncontrolled landfills in Serbia without any pretreatment, and that significant amounts of these materials have already accumulated in the landfills. The substantial amounts of land-filled plastics represent not only a loss of valuable recourses, but also pose a serious treat to the environment and human health, and if the trend of direct plastic land-filling is continued, Serbia will face with grave consequences

Evaluation of house price models using an ECM approach: The case of the Netherlands

Este estudo apresenta uma abordagem raramente discutida no âmbito das finanças públicas, expondo a ideia de que o processo de endividamento é composto por um fator permanente e outro transitório. Com isso, o objetivo émensurar a parte permanente e a parte transitória do endividamento dos municípios brasileiros nos anos de 1989 a 2012. Para isso, é utilizado um método que pode ser aplicado em séries não estacionárias e não lineares, chamado de decomposição em modos empíricos. Os resultados indicam que a composição do processo de endividamento dos municípios é, em grande parte, formada pelo fator transitório da dívida, em outras palavras, os governos municipais vêm expandindo suas dívidas de modo geral em seus respectivos ciclos orçamentários.This study presents an approach rarely discussed in the ambit of public finances,exposing the idea that the process of indebtedness is composed by permanent and transitoryfactors. With this, the objective was to measure the permanent part and the transitory partof the indebtedness of Brazilian municipalities in the years 1989 to 2012. For this, a methodthat can be applied in non-stationary and non-linear series is called Decomposition inEmpirical Modes. The results indicate that the composition of the process of indebtednessof the municipalities is largely formed by the transitory factor of the debt, in other words,the municipal governments have been expanding their debts generally in their respectivebudgets cycles

Psychometric properties of the Serbian Smartphone Application-Based Addiction Scale (SABAS) and validation of the English version among non-native English speakers problematic smartphone use and smartphone addiction

The present study evaluated the psychometric properties of the Serbian Smartphone Application-Based Addiction Scale (SABAS) and the original English version of the same scale administered to a Serbian-speaking sample. In Study 1, 599 participants completed Serbian SABAS, with 189 having both test and retest data. Results suggested good internal consistency (α = .81) and test–retest reliability (ICC = .795, p < .001, 95% CI [.731, .844], rtest-retest = .803) of the scale. Convergent validity of the SABAS was evaluated through correlations with the Smartphone Addiction Scale–Short Version (SAS-SV), as well as with anxiety, depression, worry, duration, and purpose of smartphone use. Divergent validity of the SABAS was evaluated through comparing the correlations with entertainment and productive smartphone use. The modified CFA model showed an acceptable fit (χ2(8) = 25.53, p = .001, CFI = .961, TLI = .926, RMSEA = .096, SRMR = .042), confirming the unidimensionality of the SABAS. In the second study, the English SABAS, completed by 335 non-native speakers from Serbia, also showed a good fit of the single-factor model (χ2(9) = 12.56, p = .184, CFI = .990, TLI = .984, RMSEA = .036, SRMR = 0.026), and good psychometric features. Based on the study’s findings, the Serbian version of SABAS is a reliable and valid measure for screening the risk of smartphone addiction. Moreover, the English version can be used among non-native Serbian English speakers

Rückschau auf die traumatologische Kasuistik der abteilung für maxillofaziale Chirurgie des allgemeinen Krankenhauses in Osijek, von seiner gründung am 1. VIII 1968. Bis heute.

Porast povreda u maksilofacijalnoj regiji uopće, kao i sve češća pojava teških povreda ovoga područja, mogu se notirati i u našoj kazuistici. Kao što se to iz statistike vidi, tijekom naše dosadašnje djelatnosti, tj. u roku od posljednjih 15 mjeseci, bilo je 411 povreda, od čega 273 samo mekih tkiva lica, a 138 fraktura i to 128 zatvorenih i 10 otvorenih. Kod maksilofacijalnih povreda kombiniranih s povredama na drugim lokalizacijama tijela, vršene su konzultacije sa odnosnim specijalistima i prema potrebi se primjenjivala timska obrada, a tretiranje se obavljalo prema redu hitnosti. Vanjske rane, rane u usnoj šupljini, kao i raznovrsni prijelomi kosti facijalnog dijela glave tretirani su u zato određenom roku i po principu i tehnici opisanima u suvremenoj literaturi. Rane mekih tkiva dobro su zarašćivale, a kod svih dosad dovršenih tretmana frakture kosti lica došlo je u određenom roku i do konsolidacije i naknadne zadovoljavajuće funkcije odnosnih organa, osim u dva slučaja teških povreda vatrenim oružjem, s kontinuitetnim defektom kosti mandibule, koji su još u tretiranju. U četiri su slučaja bili potrebni rekonstruktivni operativni zahvati, koji su već dijelom u toku, a kod svih povreda izvršena je, poslije skidanja imobilizacijskih naprava, prema potrebi, kompletna sanacija zuba, s punom definitivnom protetskom nadoknadom.The general upward trend in injuries of the maxillofacia region in general, and the steadily growing number of serious injuries of this region has been noted in our casuistics too. Statistics show that in the course of our activity in this newly established Department, i.e. within the last 15 months 411 injuries were registered. Of these 273 were of the soft tissue of the face alone and 138 were fractures. Hundred and twenty-eight fractures were of the closed type and 10 were compound fractures. In maxillofacial injuries combined with injuries of other sites in the body consultations were undertaken with the responsible specialists and where necessary team-work was applied. Treatment was carried out according to the order of urgency. External wounds, wounds in the oral cavity and various fractures of the bones of the facial part of the head were therefore treated urgently and following the principles and technique described in contemporary literature. The wounds of the soft tissue healed well and in all so far treated fractures of the facial bones consolidation occurred within the normal period. Subsequent satisfactory functions of the organs concerned was also achieved with the exception of two cases of very serious injuries inflicted by fire arms with continuous defect of the mandibullar bone. These patients are undergoing special treatment. In four cases reconstructive operative interventions were necessary. These patients are partly undergoing treatment. After removal of the immobilization devices in all of these injuries complete repair of the teeth was undertaken with full definitive prosthetic replacement.Die Zunahme von Verletzungen in der maxillofazialen Region und die immer grössere Zahl von Schwerverletzten dieses Gebietes, geht auch aus unserer Kasuistik hervor. Im Laufe unserer Tätigkeit hatten wir 411 Verletzungen, darunter 273 nur der Gesichts-Weich-teile und 138 Kieferbrüche, wovon 128 geschlossene und 10 offene.Falls diese Verletzungen mit Traumen anderer Körperteile verbunden waren, wurden entsprechende Fachärzte zu Rate gezogen, und nach Bedarf die Behandlung als Teamerbeit durchgeführt. Äussere Wunden, Wunden in der Mundhöhle, als auch verschiedene Knochenbrüche des fazialen Gebietes, wurden nach den herschenden Prinzipien und Technik behandelt. Weichteilwunden heilten gut aus; sämtliche Kieferbrüche sind in der vorgesehenen Frist ausgeheilt, so dass die Funktion zufriedenstellend war. In vier Fällen waren wiederherstellende operative Eingriffe notwendig. Bei allen wurde, nach der Abnahme der Schienen, je nach Bedarf, die prothetische Versorgung durchgeführt

Anthropometrische, kraft-, ausdauer-und flexibilitätsmerkmale männlicher elite-eiskletterer und sportkletterer

Objective: Purpose of this study was to compare elite male ice climbers and sport climbers for their anthropometry, muscular strength, endurance, and flexibility. Although there is a certain overlap between these two activities, sport climbing, which recently became an Olympic discipline, has been studied significantly more than the ice climbing. Hence, the second aim was to indirectly determine whether sport climbing training processes and nutrition can be beneficial for the ice climbing athletes. › Methods: 23 male ice climbers of the Ice Climbing World Cup 2010 in Saas Fee (Switzerland) who all reached the final round were compared to 23 elite male sport climbers, which refers to “on sight” climbing grade of VII+/6b (UIAA/French) or higher. Measurements included anthropometry, three different tests for flexibility, two for strength and two for endurance. › Results: Ice climbers have more fat in the trunk region (Fat%-T), have significantly less handgrip strength in both hands, as well as strength to mass ratio (SMR) of the dominant hand. In the test “foot raise”, ice climbers showed significantly less flexibility. › Conclusion: Results indicate that ice climbers have not only higher body fat percentage, probably as an adaption to cold environment but also lower strength and flexibility than sport climbers. With such data, we can conclude that sport climbing training protocols for development of strength, endurance and flexibility can be potentially beneficial to ice climbers.Ziel: Ziel dieser Studie war es, männliche Elite-Eisk letterer und Sportk letterer hinsichtlich ihrer Anthropometrie, Muskelkraft, Ausdauer und Flexibilität zu vergleichen. Das zweite Ziel war zu bestimmen, ob Trainingsprozesse und Ernährung auf der Grundlage von Untersuchungen an Sportk letterern auch für Eiskletterer von Vorteil sein können.›Methoden: 23 männliche Eisk letterer des Ice Climbing World Cup 2010 in Saas Fee (Schweiz), die alle in die Finalrunde kamen, w urden mit 23 männlichen Elite-Sportkletterern verglichen, die „on sight“ einen K lettergrad von V II+/6b (UIA A/French) oder hö-her aufw iesen. Die Messungen umfassten die Anthropometrie, drei verschiedene Tests für Flexibilität, zwei für K raft und zwei für Ausdauer.›Ergebnisse: Eisk letterer haben mehr Fett im Rumpf bereich (Fat%-T), signifikant weniger Handgriff kraft in beiden Händen sowie Kraft-zu-Masse-Verhältnis (SMR) der dominanten Hand. Eiskletterer zeigten deutlich weniger Flexibilität imHüftbereich.›Schlussfolgerung: Die Ergebnisse zeigen, dass Eisk letterer nicht nur einen höheren Körperfettanteil haben, wahrscheinlich als Anpassung an eine kalte Umgebung, sondern auch eine gerin-gere Kraft und Flexibilität als Sportkletterer. Sportkletter-Trai-ningsprotokolle können zur Entw ick lung von Kraft, Ausdauer und Flexibilität für Eisk letterer potenziell von Vorteil sein
