Distruzione etnonazionalista della società: il caso della Bosnia

La comprensione dell'identità etnonazionale delle diverse comunità nell'Europa Centrale ed Orientale è specifica in quanto determinata soprattutto dall'appartenenza culturale dei vari gruppi etnici, legata in un modo speciale alle origini confessionali e a quelle linguistiche, che in molti casi trascende i confini degli stati in questione. Il caso della Bosnia ed Erzegovina è stato scelto perché dimostra in modo più trasparente la forza devastatrice dell'etnonazionalismo. Se si poteva mettere in questione l'esistenza dei presupposti per l'integrazione dei popoli jugoslavi in varie forme di comunità culturale, economica o politica, la Bosnia ed Erzegovina non poteva essere definita creazione artificiale o di compromesso da parte di diverse volontà politiche considerato che era una società altamente integrata

Constituting the Social Basis of the EU: Reflections from the European Margins

The article addresses significant aspects of the constitution of the European Union’s social basis from the broader perspective of a European space under construction. The specific point of view regards the process of Europeanization through enlargement to the post-socialist Eastern and South European countries, and conditionality as its main instrument. In the light of the five-year moratorium proposed by the Juncker Commission in 2015, the process is examined particularly from its margins by considering the case of Bosnia and Herzegovina (BiH), i.e. the last country in the ‘Western Balkans’, together with Kosovo, that is not yet a candidate for EU membership. The analysis aims to shed light on two different and conflictual forms of agency: first, the institution building process through accession procedures; second, social dissent patterns and citizens’ mobilization in Bosnia and Herzegovina. The purpose is to analyze if and how these diverse agencies cross borders and soften boundaries to constitute an emerging European society. A constant methodological concern of this study is if and how an ethnography of the process may contribute to the analysis of European integration in its complex, non-linear and often contradictory nature (Kauppi 2013

Factors of the rural tourism development of Sirinicka Zupa in Kosovo and Metohija

The authors analyse a current problem from the economic point of view on the rural development of Sirinicka Zupa and the significance of financing rural tourism. Starting hypothesis of authors is that the rural tourism directs a total agro complex towards the sustainable development of this Serbian enclave. The term "agro tourism" refers to an unbreakable interdependence between agriculture and tourism, and therefore is inevitable to solve in parallel the issues of agricultural holdings funding in the Serbian enclave Sirinicka Zupa in Kosovo and Metohija. The quality observation method, the analysis method, the synthesis method and interviews helped the authors in getting the information on business problems of agricultural holdings, and the authors were trying to give the answers, suggestions and solutions in order to help Serbian people in enclaves to engage in and develop tourism, and therefore also to survive and live on the centuries-old hearths.Publishe

Non-invasive treatment of multiple enamel hypoplasia: A case report

Objective. Enamel hypoplasia is a quantitative disorder of enamel deposition during the secretory phase and is characterised by a deficiency of the enamel, while hypomineralization is a qualitative disorder caused by incomplete mineralization and maturation of the enamel, followed by the porosity of the solid dental tissues and the opalescent tooth colour. Clinically, hypoplasia is a risk for caries, tooth sensitivity, erosion, and affects the aesthetic appearance of a patient with a psychological connotation. The aim of the paper is to present the case report, the possibility of preventive measures and restorative treatments with minimally invasive requirements in these patients. Methods. At the Faculty of Medical Sciences, University of Kragujevac, in March 2018, a thirteen-year-old boy was diagnosed with isolated hypoplastic enamel defects on teeth 24, 25, 26, 33 and 34. Results. Enamel hypoplasia was diagnosed by anamnesis, clinical and radiological examination. Preventive measures and conservative interventions were used to prevent progressive abrasion and early tooth loss due to caries and its complications. Conclusion. Early diagnosis, timely preventive methods and minimally invasive restorative treatment can correct anomalies and prevent possible complications.Publishe

Quinones and non-quinones from the defensive secretion of unciger transsilvanicus (Verhoeff, 1899) (diplopoda, julida, julidae), from Serbia

A complex mixture of compounds was identified from the secretion of specimens of Unciger transsilvanicus. Phenol and p-cresol were detected for the first time in the family Julidae, and for the second time in the order Julida. Thirteen quinones were identified, with a great relative abundance of toloquinone and 2-methoxy-3-methyl- 1,4-benzoquinone. Hydroquinone was detected for the first time in the order Julida. Besides these compounds, isopentyl hexacosatetraenoate and isopentyl esters of saturated and unsaturated fatty acids with chain lengths from C-14 to C(20)were identified. The most abundant non-quinone compound was isopentyl eicosenoate. The relative abundance of quinone and non-quinone in the defensive fluid of U transsilvanicus was 77% and 23%, respectively. The phylogenetic importance of the registered compounds is briefly discussed

Lipophilicity assessment of some 5,5-disubstituted hydantoins by the means of reversed phase liquid chromatography

The retention of some 5,5-disubstituted hydantoins was investigated by reversed phase high performance thin-layer chromatography (RP HPTLC) and reversed phase high-pressure liquid chromatography (RP HPLC). The mobile phases were mixtures of methanol-water and acetonitrile-water in various volume fractions. In order to explore and visualize similarities and differences among the investigated compounds and chromatographic system, Principal Component Analysis (PCA) was used. Results show that the experimental lipophilicity indices estimated from retention data (Rm,w, log kw) and PC1 are directly correlated with logP values at a high significant statistical level.Ispitano је retenciono ponašanje derivata 5,5-disupstituisanih hidantoina primenom dve tehnike tečne hromatografje na obrnutim fazama, i to hromatografije na tankom sloju velike moći razdvajanja (HPTLC) i tečne hromatografije pod visokim pritiskom (HPLC).

Efficient removal of priority, hazardous priority and emerging pollutants with Prunus armeniaca functionalized biochar from aqueous wastes: Experimental optimization and modeling

This paper investigates the ability of the phosphoric acid functionalized Prunus armeniaca stones biochar (AsPhA) prepared by thermochemical activation to remove lead (Pb2+), cadmium (Cd2+), nickel (Ni2+), naproxen and chlorophenols from aqueous wastes. The engineered biochar was characterized using the Scanning Electron Microscopy, Energy-dispersive X-ray Spectroscopy, Fourier Transform Infrared Spectroscopy and Brunauer, Emmett and Teller technique. The batch studies were performed by varying the initial pH of the solution (2-9), adsorbent dosage (0.2-10 g L-1), contact time (5-60 min), temperature (22, 32 and 42 degrees C) and initial adsorbate concentration (5-500mg L-1). With the optimal process conditions, the adsorption efficiency was over 95% (100 mg L-1). The results were fitted with three kinetic and three equilibrium theoretical adsorption models. The adsorption process has good correlation with pseudo-second-order reaction kinetics. Adsorption mechanism was found to be controlled by pore, film and particle diffusion, throughout the entire adsorption period. The monolayer adsorption capacities were found to be 179.476, 105.844 and 78.798mg g(-1) for Pb2+, Cd2+ and Ni2+, respectively. Thermodynamic parameters such as Gibbs energy, enthalpy and entropy were also calculated. Additionally, preliminary results indicated a strong affinity of the biochar for selected organic micropollutants: naproxen and chlorophenols. Based on desorption study results, biochar was successfully regenerated in 3 cycles with diluted phosphoric acid produced as a waste stream during washing of the biochar after thermochemical activation. The experimental results were applied in a two-stage completely stirred tank reactor design. Cost estimation of AsPhA production substantiated its cost effectiveness and adsorption costs of selected pollutants were 5 times lower than with the commercial activated carbons. Based on the low-cost and high capacity, engineered biochar can be used as a highly efficient eco-friendly adsorbent for removal of heavy metal and organic micropollutants from wastewaters systems

Utilization of fruit processing industry waste as green activated carbon for the treatment of heavy metals and chlorophenols contaminated water

Plum stones, as a part of industrial and municipal organic waste, were used as a precursor for preparation of a low-cost activated carbon. Engineered, thermochemically-modified adsorbent was used to remove lead (Pb2+), cadmium (Cd2+), nickel (Ni2+) and chlorophenols from an aqueous solution. The characterization of the medium was performed using standard instrumental analysis. Additionally, the assessment included the influence of pH, adsorbent dosage, temperature, contact time and initial metal concentration on the separation efficiency in the batch-operational mode. With optimal working conditions, the process efficiency of over 95% was accomplished. The equilibrium and kinetic studies of adsorption were done. The pseudo-second order model described the adsorption kinetics best. The maximum adsorption capacity of the engineered adsorbent for Pb2+, Cd2+ and Ni2+ ions was calculated from the Langmuir isotherms and found to be 172.43 mg g(-1), 112.74 mg g(-1) and 63.74 mg g(-1), respectively. Preliminary results indicate a strong affinity of the separation medium for chlorophenols. Thermodynamic parameters such as Gibbs energy, enthalpy and entropy were calculated. Regeneration of the saturated adsorbent was conducted, with diluted phosphoric acid produced as a waste stream, during the washing of the adsorbent after activation. Based on the desorption study results, the activated carbon was successfully regenerated in 3 cycles. Mutual influence of ions was analyzed in multicomponent systems. The real system production and operational costs analysis confirmed a possibility for a successful implementation of the highly efficient, eco-friendly engineered adsorbent in the field of cost-effective wastewater treatment.The peer-reviewed version: [http://cer.ihtm.bg.ac.rs/handle/123456789/2942
