Rad predstavlja dosad neproučenu rukopisnu prigodnicu zagrebačkog kanonika Georga Wyrffela sastavljenu na starogrčkom, kojom je popratio pobjedu hrvatskih snaga pod vodstvom bana Jurja Draškovića u ...bitci protiv Turaka na rijeci Glini. Budući da kontekstualizacija ovog neuobičajenog pjesničkog pothvata izravno ovisi o točnoj identifikaciji osobe koja ju je sastavila, rad također ispravlja netočne stare i donosi nove biografske podatke o Georgu Wyrffelu.
Članak oživljava lokaciju, identitet kompozitora i prvih izvođača hrvatske himne. Napisan je na temelju novih arhivskih i knjižničnih istraživanja te postojeće literature. Započinje podacima i ...činjenicama o životu i karijeri krajiškog oficira Josifa Runjanina, rođenog 1821. godine, a završava viješću iz 2019. o inicijativi da se u Glini otvori Muzej državne himne, usredotočujući se na izabrana događanja u pojedinim razdobljima (razdoblje Runjaninova života; razdoblje od njegova ulaska u historiografiju glazbe do kraja Prvog svjetskog rata; međuratno razdoblje; razdoblje od 1941. do 1945.; poslijeratno razdoblje; razdoblje od raspada Jugoslavije do vojne akcije Oluja; razdoblje od 1995. naovamo). Autorstvo Josifa Runjanina i polet prvih izvođača, članova “Srpskog dobrotvornog pjevačkog društva u Glini”, izvlači iz duboke sjene i osvjetljava neizbrisiv trag i neotuđiv doprinos istaknutih Srba i srpskih organizacija, u ovom slučaju iz Gline, himni hrvatskog naroda.

U radu je opisan samozbijajući beton s unutarnjom njegom proizveden djelomičnom zamjenom sitnozrnatog agregata laganim agregatom od ekspandirane gline i agregatom od letećeg pepela. Ispitana su ...svojstva betona u svježem stanju i mehanička svojstva samozbijajućeg betona, pri čemu je najviše 25 % agregata (volumenski) zamijenjeno. Rezultati ispitivanja pokazuju da su sve mješavine zadovoljile zahtjeve za samozbijajući beton. Osim toga, mješavina s 15 % agregata od ekspandirane gline i mješavina s 15 % agregata od letećeg pepela postižu veću čvrstoću pri uvjetima unutarnje njege u usporedbi s čvrstoćama koje su postigle kontrolna mješavina i ostale mješavine.
Provider: - Institution: - Data provided by Europeana Collections- The subject of the work presented in this dissertation was to investigate the sorption of Cu (II)- ions onto synthetic ...hydroxyapatite (HAP)-and natural sorbents: zeolite, clay and diatomite, in order to define process equilibrium and kinetics under different conditions. Physico-chemical characterization showed that synthetic HAP was consisted of pure non-stoichiometric, calcium deficient, calcium hydroxyapatite, zeolite of clinoptilolite, while clay was the composite of illite, kaolinite and montmorillonite. The main phase of diatomite was amorphous silicon dioxide. Also, HAP and zeolite were characterized as a mesoporous sorbents with specific surface areas of 58 m2 / g and 23 m2 / g, respectively, while the clay and diatomite were non-porous, with low specific surface areas of 8 m2/g and 5 m2 / g. pHPZC of 6.6 was defined for HAP, clay and diatomite, while higher value of 7.5 was obtained for zeolite. Obtained results for pHPZC for HAP, clay and zeolite are in good agrement with literature, while pHPZC of diatomite has not been published. The investigation of influence of initial solution pH in the range of 2 - 10 on equilibrium showed that the final pH values varied depending on the tested sorbent. In general, final pH values increased the most in pH range 2 – 4. Areas of the plateau, where the final pH values were independent on the initial pH indicating the buffering properties of sorbents, were dependent on the sorbent and the concentration of metal ions in solution. Further increase of initial pH caused increase of final pH values. The plots of sorbed amounts vs. initial pH were of the same shape as plots pH final vs. pH initial, which can be explained with higher solubility of sorbents and their components and competition between Cu(II) and H+ ions in the strong acidic media. The final pH increase above 6 caused copper hydroxide precipitation and 100 % removal of metal ions from solution. The maximal sorption capacities at room temperature decreased in the order: HAP (0,585 mmol/g) > zeolite (0,128 mmol/g) > clay (0,098 mmol/g) > diatomite (0,047 mmol/g). In these experiments pH drop was observed, signifying the existence of specific cation sorption mechanism which was the most dominant during the sorption onto diatomite. Also, ion-exchange mechanism between Cu(II)- ions and Ca2+ ions from HAP surface was responsible for metal bonding, as well as ion-exchange with Na+, K+, Ca2+, Mg2+ from surfaces of natural mineral sorbents. The stability of system sorbent/ metal was investigated in acidic leaching solution and it was dependant on sorbent type, as well as on the previously loaded amounts. With increase of loaded metal amounts onto HAP and diatomite, the percentages of desorption also increased, while the opposite was observed for desorption from zeolite and clay- the samples with higher loadings were more stable in the acidic media. The desorbed amounts expressed in mmol/g or mg/g were higher for the more saturated samples, independent of sorbent type. The process kinetics was investigated as a function of initial metal concentration in batch system, on horizontal shaker. It was shown that the sorption onto non-porous sorbents, clay and diatomite was limited with diffusion film resistance. Contrary, the film diffusion was significant only during the first 15 minutes of process onto HAP and zeolite. The values of volumetric mass transfer coefficient kf•a were calculated using Boyd model. The values of kf•a were independent on initial concentration, and varied around averaged value of: 0,046 1/min for HAP, 0,023 1/min for zeolite, 0,017 1/min for clay and 0,031 1/min for diatomite. According to this it can be concluded that kf•a was a function of particle size for nonporous sorbents, i.e. it was highest for the smallest particles because specific surface area was higher. The obtained values for kf•a decreased in the order: HAP>diatomite>zeolite>clay, but probably this order would be different if the zeolite particles were smaller, where value for kf•a onto zeolite would be higher. Using pore diffusion models, it was shown that the effective diffusivities slightly decreased with c0 increase, while for sorption onto zeolite Deff was independent on c0. Dependence of Deff on c0 and independence of kfa on c0 can be explained by counter diffusion of cations released from sorbent surface, as well as with electrostatic repulsion of positive charged particles. These phenomena can be neglected in the fluid mass, but not inside the pores. From the analysis of results obtained for sorption onto HAP in the agitated vessel, it was observed that kf•a calculated for the first 10 minutes of the process was independent on sorbent mass and agitation speed, but slightly decreased with initial metal concentration increase, which was probably caused by the existence of pore diffusion resistance. Contrary, kf•a calculated for zeolite was independent on metal concentration and sorbent mass, but increased with agitation speed increase and particle size decrease. Effective diffusivities for sorption onto HAP and zeolite were independent on sorbent mass and agitation speed. Deff decreased with c0 increase because of counter diffusion inside the pores, but increased with particle size increase. Finally, it can be concluded that for the first 15 minutes of the sorption onto HAP and zeolite using shaker, the limiting step was film diffusion, and after that the pore diffusion, where sorption occurred inside the mesopores. Also, the mixing using shaker was not good enough, thus the obtained values for kfa and Deff were significantly lower than the values obtained for the sorption in the agitated vessel. The sorption onto HAP in the agitated vessel was limited only by pore diffusion because the film diffusion and surface saturation occurred almost instantaneously. The sorption onto zeolite in agitated vessel was governed by film diffusion during the first 10 minutes, whereas after that by diffusion inside the pores.- Predmet rada ove doktorske disertacije je bio ispitivanje sorpcije Cu (II)- jona sintetičkim HAP-om i prirodnim sorbentima zeolitom, glinom i dijatomitom, u cilju definisanja ravnoteže i kinetike procesa pri različitim uslovima. Fizičko-hemijska karakterizacija je pokazala da se sintetički HAP sastoji od čistog nestehiometrijskog, kalcijum deficitarnog, kalcijum-hidroksiapatita, zeolit od klinoptilolita, dok je glina kompozit ilita, kaolinita i montmorilonita. Glavna faza u dijatomitu je amorfni silicijum-dioksid. Takođe, HAP i zeolit su okarakterisani kao mezoporozni sorbenti specifičnih površina 58 m2/g i 23 m2/g, redom, dok su se glina i dijatomit pokazali neporozni, nižih specifičnih površina od 8 m2/g i 5 m2/g. Definisana je pHPZC koja iznosi 6,6 za HAP, glinu i dijatomit, dok je kod zeolita nešto viša i iznosi 7,5. Dobijene vrednosti pHPZC HAP-a, gline i zeolita su u dobroj saglasnosti sa literaturom, dok pHPZC dijatomita do sada nije objavljena. Ispitivanjem uticaja inicijalne pH vrednosti rastvora na ravnotežu, pokazano je da se finalne pH vrednosti razlikuju u zavisnosti od ispitivanog sorbenta. Generalno, ravnotežne pH vrednosti najviše rastu sa porastom inicijalnih pH rastvora u oblasti 2 - 4. Oblast platoa, u kome su finalne pH vrednosti nezavisne od inicijalnih i koja ukazuje na puferska svojstva sorbenata, zavisi od vrste sorbenta i koncentracije jona metala u rastvoru. Dalje povećanje polaznih pH prouzrokuje porast i finalnih. Krive zavisnosti sorbovane količine od inicijalnih pH su istog oblika kao i krive pH finalno-pH inicijalno, što se objašnjava povećanom rastvorljivoću sorbenata ili njihovih komponenti i kompeticijom Cu(II) i H+ jona u jako kiselim rastvorima. Porast finalnih pH iznad 6 dovodi do precipitacije bakar – hidroksida što rezultira 100% uklanjanjem jona metala iz rastvora. Maksimalni sorpcioni kapaciteti prema Cu(II)- jonima, na sobnoj temperaturi, opadaju u nizu: HAP (0,585 mmol/g) > zeolit (0,128 mmol/g) > glina (0,098 mmol/g) > dijatomit (0,047 mmol/g). U datim eksperimentima je utvrđen pad pH vrednosti rastvora u odnosu na početnu, što ukazuje na postojanje mehanizma specifične sorpcije, koji je najdominantniji tokom sorpcije na dijatomitu. Za vezivanje jona metala ispitivanim materijalima, odgovoran je i mehanizam jonske izmene, gde se Cu(II)- joni izmenjuju sa Ca2+ jonima sa površine HAP-a, odnosno sa jonima Na+, K+, Ca2+, Mg2+ sa površine prirodnih sorbenata. Stabilnost sistema sorbent/jon metala je ispitana u kiselom rastvoru za izluživanje i zavisi od vrste sorbenta, kao i prethodno sorbovane količine Cu(II)- jona. Sa porastom sorbovane količine na uzorcima HAP-a i dijatomejske zemlje, raste i procenat desorbovane količine, dok desorpcija sa zeolita i gline pokazuje suprotan trend - u kiseloj sredini su stabilniji uzorci sa većom sorbovanom količinom jona metala. Ako posmatramo desorbovanu količinu izraženu u mmol/g ili mg/g, ona je veća na uzorcima koji su više zasićeni, nezavisno od vrste sorbenta. Kinetika procesa je ispitana u različitim šaržnim sistemima. Prvi sistem su pojedinačne šarže sa mešanjem na horizontalnom šejkeru, gde je proces sorpcije ispitan u funkciji od početne koncentracije Cu(II)- jona na svim ispitanim sorbentima. Drugi šaržni sistem je sud sa mešalicom u kom je ispitana kinetika procesa sorpcije HAP-om i zeolitom u funkciji od koncentracije sorbata, mase sorbenta, brzine mešanja, a za zeolit i od granulacije sorbenta. Pokazano je da je sorpcija glinom i dijatomitom, kao neporoznim sorbentima, limitirana otporom u filmu fluida. Nasuprot tome, difuzija u filmu fluida tokom sorpcije na šejkeru HAP-om i zeolitom je značajna na početku procesa, tokom prvih 15 minuta. Vrednosti zapreminskog koeficijenta prenosa mase su izračunate Boyd-ovim modelom. Dobijene vrednosti kf•a su nezavisne od početne koncentracije Cu(II)- jona u rastvoru i variraju oko srednje vrednosti 0,046 1/min za HAP, 0,023 1/min
We proposed in among below the recovery of archeological research what was done now more 40 years ago, at Budureasca, a collinear area in north-east Prahova County. Our work is meant to be a support ...for publishing the results of the research by the archaeologists, during activity or possibly a resonable time after the start. The work performed and the problems encountered for the exposre of the information below, stengthened this conviction. Also, we follow the introducing in the scientific field of some rare archaeological finds in Muntenia area which can be evaluated by other researchers in a more varied background. Between the findings of Budureasca, which can be considered specials are those belonging to the funeral decorations of Bronze Age. In area " Puţul Tătarului", were intercepted more funeral arrangements of whichonly a few have been fully investigated. They were situated on an necropolis assigned to an early aspect of the bronze era with analogy to the cultural surroundings of Glina III– Schnekenberg, chronologically placed lightly prior an early stage of Monteoru’s culture. Because of the incomplete archeological information, this note have only a preliminary character. From the point of view of the funerary arrangements, cist graves surrounded by ring of rocks, over which mounds of ground were builded and other elements too, of rite and ritual, the Budureasca necropolis has for now in these area an exceptional character. We do not know in the area that is discussed similar discoveries for this chronological extent. We also notice the existence in this necropolis of possible secular burials rendered by the presence of incinerated bones laid by the rings interior, of some vessels disposed in the exterior of the cystic. The chronological segment that was used this necropolis covers the last stages of the evolution of the Glina culture and the early Monteoru culture. The researchs are in progress in this archaeological site and could offer the chance discovery of new funeral arrangements or the completion of partially captured oldest archaeological excavations.
În rândurile de mai jos ne-am propus valorificarea unor cercetări arheologice derulate acum mai bine de 40 de ani la Budureasca, în zona colinară din nord-estul judeţului Prahova. Nota noastră se doreşte a fi o pledoarie pentru publicarea rezultatelor cercetărilor de către arheologi în timpul activităţii sau eventual într-un timp rezonabil de la derularea acestora. Munca depusă şi problemele ridicate pentru a expune informaţiile de mai jos ne-au întărit această convingere. De asemenea, urmărim introducerea în circuitul ştiinţific a unor descoperiri arheologice relativ rare în zona colinară a Munteniei ce vor putea fi evaluate şi de alţi cercetători într-un context mai larg. Între descoperirile de la Budureasca ce pot fi considerate deosebite sunt cele atribuite unor complexe funerare din epoca bronzului. În punctul „ Puţul Tătarului” au fost interceptate prin săpături arheologice mai multe complexe funerare dintre care doar o parte au fost cercetate integral. Ele au fost încadrate unei necropole atribuite unui aspect timpuriu al epocii bronzului cu analogii în mediul cultural Glina III– Schnekenberg, cronologic plasate uşor anterior unei etape timpurii a culturii Monteoru. Date fiind informaţiile incomplete pentru aceste complexe nota de faţǎ are un caracter preliminar. Din prisma amenajărilor funerare, ciste înconjurate de ringuri din piatră, peste care s-au construit movile de pământ, dar şi a altor elemente de rit şi ritual, necropola de la Budureasca are deocamdată în această zonă un caracter excepţional. Nu cunoaştem în arealul pus în discuţie descoperiri similare pentru acest orizont cronologic. Mai remarcăm şi existenţa în această necropolă a unor posibile înmormântări secundare evidenţiate de prezenţa oaselor incinerate depuse în interiorul ringurilor, a unor vase dispuse în afara cistelor. Segmentul cronologic în care a fost utilizată această necropolă acoperă ultimele etape ale evoluţiei culturii Glina şi începutul culturii Monteoru. Cercetările ce se află în curs de derulare în acest sit ar putea oferi şansa descoperirii unor noi complexe sau finalizarea unora surprinse parţial în vechile săpături arheologice.
