In confinibus Turcorum: Ljudi režima Matije Korvina u ugarsko-osmanskom pograničju kasnog petnaestog stoljeća

The paper discusses the backgrounds and careers of several lesser-known officials who occupied various positions along the Hungarian-Ottoman frontier during the reign of King Matthias Corvinus of Hungary (r. 1458-1490). By examining their biographies and their place within the ruling elite of Corvinus’s Hungary, the study moreover elucidates how changes in King Matthias’s authority in the borderlands were reflected in the changes in his personnel policies, showing that the king gradually gained more control over his southern lands through a growing network of loyal retainers. The latter, moreover, successfully replaced the vestiges of older regimes – whose representatives often stood in opposition to royal politics – thus allowing the introduction of greater royal control.Rad raspravlja pozadine i karijere nekoliko manje poznatih službenika koji su zauzimali različite službe u ugarsko-osmanskom pograničju tijekom vladavine ugarskoga kralja Matije Korvina (1458-1490). Analizirajući njihove biografije i mjesta u vladajućoj eliti Korvinove Ugarske, ova studija nadalje ilustrira kako su se promjene u kraljevom autoritetu u pograničju reflektirale u promjenama u kadroviranju na tom prostoru, pokazujući da je kralj postepeno stjecao kontrolu nad svojim južnim zemljama uz pomoć rastuće mreže odanih familijara. Ovi su, konačno, uspješno zamijenili ostatke starijih režima, čiji su predstavnici redovito ustajali protiv kraljevske politike, i tako dozvolili uspostavu čvršće kraljeve kontrole

The Process of Bordering at the Late Fifteenth-Century Hungarian-Ottoman Frontier

Following the Ottoman conquest of the Despotate of Serbia in 1459 and the Kingdom of Bosnia in 1463, a new phase of Hungarian-Ottoman relations was introduced. With the disappearance of the Hungarian "buffer" towards the Ottoman-held areas, the territories of the two states became adjacent, and their mutual frontier had to be negotiated afresh. By looking into all available material, Latin, Slavonic, and Ottoman, this paper aims to trace negotiations between the two sides in the period of King Matthias Corvinus’ reign and discern their content and application with regard to borders. It tackles the demarcation of the border between the two sides, and highlights the mechanisms employed for its institutional maintenance

Osnovne aktivnosti za dodjelu CE znaka za proizvode definirane standardima serije EN 286

The series of harmonized standards EN 286 – Parts 1, 2, 3 and 4 which support Directive 87/404/EEC – Simple pressure vessels, is related to tanks of air braking systems for motor and rail vehicles of different shapes, materials, dimensions and operational parameters, which determine their diverse application. However, as vessels under pressure they also present a potential hazard, either when active or when idle. In order to allow the placement of these products and their use on the European market without any limitations, certain activities have to be undertaken on CE marking of these products, meaning the criteria for awarding of the CE mark must be fulfilled. The course of the awarding of the CE mark is determined by the function of value, meaning the products of pressure and volume of vessel, pursuant to which the manufacturer selects an adequate modular approach.Serija harmoniziranih standarda EN 286 – Dijelovi 1, 2, 3 i 4, koji podržavaju Direktivu 87/404/EEC – Simple pressure vessels (Jednostavne posude pod pritiskom), odnosi se na rezervoare zračnih kočnih sistema motornih i šinskih vozila.različitih oblika, materijala, dimenzija i radnih parametara, što determinira njihovu raznovrsnu primjenu..

Analiza rutina tekućinskom kromatografijom visokih performansi u vrstama Allium iz Bosne i Hercegovine

Rutin is quercetin heteroside widely present in plants that exhibit many health-beneficial effects, such as strengthening the capillary walls, reducing the harmful effects of LDL cholesterol, and reducing the risk of cardiovascular diseases. Rutin was determined from three Allium species (A. cepa, A. sativum, and A. ursinum) collected in Bosnia and Herzegovina by the HPLC method associated with electrochemical detection. The analysis was performed from methanol extracts of bulb and leaf of garlic, bulb and leaf of onion, and leaves of wood garlic. Rutin was present in all of the examined samples. The highest rutin content was found in garlic leaves (0.78 ± 0.09 mg g–1), and the lowest in onion bulbs (0.04 ± 0.10 mg g–1). The contents of rutin were higher in leaf samples, suggesting that leaves of onion and garlic are recommended as a better natural source of this glycoside.

Udio rutina određen je u tri vrste roda Allium (A. cepa, A. sativum i A. ursinum) koje rastu u Bosni i Hercegovini primjenom tekućinske kromatografije visoke učinkovitosti s elektrokemijskom detekcijom (HPLC-ECD). Analiza je provedena u metanolnim ekstraktima lukovice i lista češnjaka, lukovice i lista crvenog luka, lista medvjeđeg luka. Rutin je određen u svim analiziranim uzorcima vrste Allium. Najveći sadržaj rutina određen je u listovima češnjaka (0.78 ± 0.09 mg g–1), a najmanji u crvenom luku (0.04 ± 0.10 mg g–1). Udjeli rutina bili su veći u uzorcima lišća, što sugerira da se listovi luka i češnjaka preporučuju kao bolji prirodni izvor ovog glikozida.

Procjena rizika izloženosti operatora teškim metalima iz pepela drvenih peleta

Ash is a by-product of wood biomass combustion that must be removed daily from stoves or fireplaces. Therefore, operators or owners are exposed to the potential impact of ash. The goal of this study was to determine whether heavy metal present in wood pellet ash posed a health concern to stove operators/owners. The risk assessment procedure was carried out in several steps, including exposure evaluation, toxicity evaluation, and risk categorisation. The hazard coefficient (HQ) and non-carcinogenic hazard index (HI) were calculated for Cd, Cr, Cu, Ni, Pb, and Zn. HQ had the highest value for the ingestion pathway (3.62 ∙ 10–6), and the value for non-carcinogenic HI was 3.70 ∙ 10–6. The value HI < 1 suggests that there is no risk to operator health related to heavy metals in analysed wood pellets ash. The carcinogenic risk (CR) was calculated for Ni, Pb, Cr, and Cd, and the values were within the permitted limits. The risk assessment based on HI and CR indicators proved that there was no significant health concern regarding exposure to the analysed ashes.Pepeo je nusproizvod izgaranja drvne biomase koji se svakodnevno mora uklanjati iz peći ili kamina. Stoga su operateri ili vlasnici izloženi potencijalnom utjecaju pepela. Ovo istraživanje ima cilj procijeniti zdravstveni rizik izloženosti operatera/vlasnika pepelu drvenih peleta zbog sadržaja teških metala. Postupak procjene rizika proveden je u nekoliko koraka uključujući procjenu izloženosti, procjenu toksičnosti i kategorizaciju rizika. Izračunati su koeficijent opasnosti (HQ) i indeks nekarcinogene opasnosti (HI) za Cd, Cr, Cu, Ni, Pb i Zn. HQ je imao najveću vrijednost za izloženost putem gutanja (3.62 ∙ 10–6), a vrijednost za nekarcinogeni HI bila je 3.70 ∙ 10–6. Vrijednost HI < 1 ukazuje na to da sadržaj teških metala u analiziranom pepelu ne predstavlja rizik za zdravlje operatera. Karcinogeni rizik (CR) izračunat je za Ni, Pb, Cr i Cd, a vrijednosti su bile unutar dopuštenih granica. Rizik procijenjen primjenom HI i CR pokazatelja potvrdio je da ne postoji značajna opasnost za zdravlje osoba koje dolaze u kontakt s analiziranim pepelom

Information networks – concept, classification and application

An information network is a structure used for transmitting various forms and types of information. In basic structure, it consists of branches that connect certain nodes. Many scientists and researchers have dealt with the problem of defining an information network, depending on the functional organization and data transmission, and also with the classification of information networks. &nbsp;Information networks have a very wide application in almost all scientific disciplines. A large number of researches are carried out on the application of information networks (e.g. bisociative, deep information network, heterogeneous information network, and space information network) in the field of medicine for easier detection of diseases, drug development, etc, and other needs to support real-time communication, massive data transmission, and data processing. In accordance with the above mentioned, the aim of this paper is to offer different approaches in defining and classifying general forms of information networks and to notice their wide application in different research disciplines
