The mobility of factors of production from the very beginnings of the theory of the optimal currency area (OCA) stands out as one of the primary mechanisms for achieving a balance of payments, i.e. sustainability of the monetary union (Mundell criterion). However, there is a significant qualitative difference between the monetary union of countries with similar income levels and the one with different development stages Namely, in the first case, labor mobility, as a rule, has short-term economic effects, while it has a longer-term (more negative) impact – especially on the long-run aggregate supply (LRAS). Many Eastern European countries, which expressed a desire to become part of European integration and the monetary union after the communist ruin, experienced this. In a previous paper, the authors set the thesis about “Impossible Trinity of Developing Countries”. In this paper, the aspiration is to confirm the validity of this theory by analyzing Greece within the period 1999-2020, specifically observing the impact of three variables (fiscal policy, social development level, and level of economic freedom) on the emigration of the population under conditions of monetary union and labor force mobility. The results obtained in this research indicate that the fiscal policy in the observed period was the most significant factor in explaining migration trends. The implications for developing countries that are currently entering (such as Croatia) or intend to enter the monetary union with more developed countries in the future are particularly significant.

Leachate water from sanitary landfills represents one of the most complex global environmental problems. This paper examines the possibility of using aluminosilicate material, pyrophyllite, from the Parsovići deposit, as an adsorbent. It was researched the influence of two granulations of pyrophyllite (0-53 μm and 0-100 μm) on the degree of adsorption of heavy metals (Fe, Ni, Mn) from leachate water from the municipal landfill "Desetine", Tuzla. The adsorption experiment was performed using the Batch method, depending on the contact time between the adsorbent and the adsorbate, the mixing speed, and the mass of the adsorbent, pyrophyllite, through two treatments. The results indicate a higher efficiency of the finer fraction of pyrophyllite, and in the competition of the three examined metals, iron is completely removed in the first treatment with both granulations and then nickel with finer granulation and manganese with coarser. After the first treatment, the unpleasant smell was removed, which is certainly a consequence of the removal of ammonia compounds as the most abundant compounds in leachate water. In these pioneering researches, pyrophyllite proved to be effective, and at the same time, it is a cheap, easily available, and environmentally friendly material for leachate water purification.

In contemporary public international law, it is increasingly common that in many countries of the world and Europe, political representatives of the peoples are calling for an inalienable right to the external self-determination of the peoples involving secession to try to achieve their independence and autonomy, forming their national states to the detriment of already existing countries in which they are currently living. However, this may cause destabilization and wars in many complex multiethnic states and the European Union. Therefore, the Aland Islands and Quebec cases are extremely important for today’s understanding of the exercise of the right to self-determination of the people in contemporary public international law, in particular as the International Court of Justice in The Hague and the domestic courts invoke them as precedents to address all future cases of reference to the right of the people to external self-determination involving secession. Based on those cases, it has developed that the issue of secession is the question of the internal legal order of each sovereign country, which should deal with this issue through its constitutional legal order, and contemporary public international law should deal with its consequences. In connection with this, it is necessary to investigate and offer answers that will highlight possible abuses of the right to self-determination of all peoples as a collective human right in contemporary public international law. Such unlawful conduct may result in adverse legal consequences, in particular, the violation of basic principles of public international law, including the principles of territoriality and sovereignty of the states, the distortion of world peace and order, economic progress, the rule of law and the pursuit of basic human rights and freedoms, as well as other collective human rights, which may ultimately be the cause of provocation and lead to international and civil wars.

Abstract The agricultural sector and growing food production needs rely on chemical fertilizers. This initially had positive effects on production, but over the last decade, the negative impacts of overuse have resulted in low crop productivity, increased pest and disease infestation, soil degradation, and consequent adverse effects on environmental parameters. As one of the possibilities in organic farming, we found vermicomposting as the most sustainable practice. For the assembly of vermicomposting, mature cattle manure was utilized in three different combinations with organic material and earthworm inoculations (the household waste, the grass clippings, and mixture). The experiment was set up by random block design in three replications. Analyses of qualitative parameters of the final product showed a pH reaction from neutral to slightly alkaline. The nitrogen compound varied between 2.7% and 2.9% and the organic carbon varied between 45.59% and 47.41%, showing a C/N ratio of 16.7‒16.67. The potassium content varied between 1.1% and 1.2% K2O, and the phosphorus content varied from 0.3% to 0.5%. The experiment gave quite good results of vermicomposting of household waste with manure, showing a neutral pH reaction, optimal content of ash and carbon with almost similar and good NPK contents and increased C/N ratio of 16.7, and with satisfying levels of trace elements and the heavy metal content under the limits. This combination of household waste and manure also showed best characterization of humic and fulvic acids in vermicompost, ranging from 1505 to 1778 cm−1 and from 729 to 998 cm−1, respectively. These results indicate that vermicomposting can increase the quality of the final product.

Ciljevi u ovome radu su analizirati vodcast kao novi oblik videoizražavanja, definirati pojam istoga te prikazati rezultate istraživanja o navikama publike naspram oblika konzumiranja medijskih sadržaja. Rezultati istraživanja predstavljaju puls javnosti te tako medijima, ali i budućim autorima vodcasta, pomažu tijekom mogućih dvojbi u analizi navika publike. Rad ističe osnovne razlike između pojmova podcast i vodcast jer se u javnosti, a i u stručnim okruženjima, navedeni pojmovi ne koriste dovoljno precizno. Razvoj novih tehnologija pokrenuo je nezaustavljiv proces konvergencije medija, koji se čini kao Pandorina kutija iz koje svakodnevno izlaze novi medijski oblici i komunikacijski obrasci koje publika rado prihvaća. Ispred tradicionalnih su medija izazovi koje moraju prevladati kako bi zaštitili, prije svega, vlastiti opstanak, potom i novinarsku profesiju. Mnogi novinari, ali i pojedinci, pokreću vlastiti internetski vodcast ili podcast, koji često ima veliku posjećenost i utjecaj. Postavlja se pitanje živimo li u vremenu i okruženju koje karakterizira velik broj informacija i medijskih sadržaja u eteru, od čega prijeti opasnost visokoga stupnja zagušenja javnosti, zbog čega se ne razlikuje bitno od nebitna.

Konvergencija je u medijski svijet donijela niz promjena ne samo u tehnološkome smislu nego i u sadržajnome i funkcionalnome. Tehnološkim razvojem omogućen je razvoj novoga multimedijskog okruženja. Na taj način brišu se granice tradicionalnih medija, odnosno došlo je do približavanja i prožimanja medija. Takvo prožimanje dovelo je do promjene u percepciji korisnika medijskih sadržaja jer postaju aktivni korisnici što se odražava na samu izradu sadržaja. Ubrzan je proces produkcije sadržaja, posebice specijaliziranih sadržaja, potrebne su veće kompetencije novinara i urednika, tržište postaje kompetitivno bilo da je riječ o komercijalnim medijima ili javnim servisima. Radio kao medij nije ostao izvan ovih procesa. Kako bi opstao kao medij, radio mora prihvatiti promjene, prilagoditi im se, a javni radijski servisi trebali bi biti lideri u tim promjenama jer su jednim dijelom financijski osigurani kroz pristojbu, pretplatu koju plaćaju građani. Svoje osnovne postulate i načela moraju prilagoditi na restrukturirani, novi, konvergirani, multimedijski, interaktivni sustav dostupan svim građanima. Cilj je rada komparativnom analizom sadržaja i formata istražiti koliko je javni radijski servis u Bosni i Hercegovini i Hrvatskoj ukorak s trendovima konvergencije, odnosno na kojoj su razini konvergencije.

Recent advances in $b$, $c$, and $s$ quark tagging coupled with novel statistical analysis techniques will allow future high energy and high statistics electron-positron colliders, such as the FCC-ee, to place phenomenologically relevant bounds on flavor violating Higgs and $Z$ decays to quarks. We assess the FCC-ee reach for $Z/h\to bs, cu$ decays as a function of jet tagging performance. We also update the SM predictions for the corresponding branching ratios, as well as the indirect constraints on the flavor violating Higgs and $Z$ couplings to quarks. Using type III two Higgs doublet model as an example of beyond the standard model physics, we show that the searches for $h\to bs, cu$ decays at FCC-ee can probe new parameter space not excluded by indirect searches. We also reinterpret the FCC-ee reach for $Z\to bs , cu$ in terms of the constraints on models with vectorlike quarks.

This research was focused on testing two water filters - Brita and Profissimo, which were filtering two and five liters of water every day. The lifespan of used filters is four weeks, while they have been actively used for eight weeks in this study to check for their efficiency after exceeded usage. Along with this, the quality of tap water, which was filtered using these two types of filters, was also tested. The experiment of the whole study was divided into three main stages: microbiological analysis, biochemical analysis, and UV-VIS spectrophotometric analysis of filtered water. The measurements were done every five days. The aim was to compare the performances of Brita and Profissimo filters after the completion of the required experiments. Based on the results that are obtained from all the analyses mentioned previously, we can conclude that Brita 2l filter was the most efficient, while Profissimo 5l filter appeared to be the least effective filter.  It is important to emphasize that the tap water in Sarajevo is generally clean and drinkable, so there is a possibility that when using more polluted water, greater deviations in the operation of filters can be observed. Overall, both water filters were usable even after two months of active usage and our measurements showed good water quality which lacks impurities and is safe for drinking.

Polymeric materials have an important role in gluing technology due to their broad application in the wood industry, metal industry, glass, and ceramics industry as well as medicine. This article discusses the basic physicochemical aspects of bonding with adhesives and also, the mechanisms of action of the adhesive materials during bonding based on polymerization processes and different types of polymerization. It was emphasized that depending on the material used in gluing, various adhesives with different physicochemical characteristics facilitate and contribute to the quality of the bonded joints. In this way, it is an insured procedure that is suitable for materials that are sensitive to the effects of heat, because welding and soldering would deform the base material and often the total degradation of its mechanical properties.

This paper presents a systematic literature review of 25 studies published between 2010 and 2021 on the relationship between government budgets and poverty reduction in developing countries. The review identifies a positive relationship between government spending on social welfare programs and poverty reduction. Specifically, increased spending on education and healthcare has been found to have a significant impact on reducing poverty levels. The review also highlights the importance of targeting government spending to specific populations and regions where poverty levels are high, and the challenges and limitations of government spending in poverty reduction efforts, such as corruption and political instability. The paper concludes with important policy implications, such as the need for increased spending on social welfare programs, addressing corruption and mismanagement of government funds, and targeting spending to specific populations and regions where poverty levels are high. The review provides insights for policymakers and practitioners working in the field of poverty reduction, emphasizing the importance of good governance, transparency, and accountability in ensuring that government budgets effectively contribute to poverty reduction.

This study offers a comprehensive examination of environmental governance within the European Union (EU), focusing on the comparative experiences of Bosnia and Herzegovina (a non-EU member) and Croatia (an EU member). The research uses policy transfer theory to investigate the practicality and effectiveness of EU-led environmental initiatives when implemented at state and local levels. The study reveals a disconnect between these initiatives and their execution, with corruption and fragile political arrangements identified as significant barriers to environmental protection. The research further underscores the complex nature of EU-driven environmental governance policies and the impact of post-war political agreements and transitional struggles on Bosnia and Herzegovina’s and Croatia’s governance structures. The methodology involves a detailed analysis of the legal frameworks, policies, and plans employed by the EU and the countries under study. The results highlight the importance of context and capacity in evaluating the effectiveness of environmental governance. The study contributes to understanding environmental governance in the EU context and provides insights into the challenges and opportunities for policy transfer to state-level governments.
