Antička luka u Zatonu otkrivena je sredinom šezdesetih godina 20. st., a sustavno se istražuje od 2002. godine. U tih 50 godina istraživanja su se vršila s većim ili manjim prekidima, i svaka ...kampanja dala je bogatstvo različitog materijala s područja od Hispanije sve do istočnog Sredozemlja. U radu se donosi pregled 78 predmeta koji se direktno ili indirektno mogu povezati s aktivnošću ribolova. Arheološkim ostatcima ribarskog alata i pribora u literaturi je pridavano malo pažnje s obzirom na to da je riječ o predmetima koji nisu previše „zanimljivi“ jer se javljaju tijekom cijele povijesti u gotovo neizmijenjenom obliku i vrlo je često, ako nema arheološkog konteksta, teško doći do nekih konkretnijih zaključaka, naročito što se tiče datiranja samih predmeta. Od ribarskog alata i pribora iz antičke luke u Zatonu izdvojene su udice, osti, utezi za mreže i igle za krpanje i šivanje mreža.
Metoda određivanja starosti pomoću radioaktivnog izotopa ugljika 14C jedna je od najčešće korištenih metoda određivanja apsolutne starosti arheoloških artefakata biološkog podrijetla. Uvidom u bazu ...Instituta Ruđer Bošković utvrđeno je da su analizirana ukupno četiri uzorka iz antičkog doba iz Zatona, dva uzorka broda Zaton 1 te po jedan uzorak brodova Zaton 2 i Zaton 3. Datirani su u rasponu od sredine 3. st. pr. Kr. do sredine 2. st. po. Kr. U radu se donosi revizija napravljenih radiokarbonskih analiza triju šivanih brodova iz antičke luke u Zatonu kod Nina i rezultati nakon dendrokronološke kalibracije konvencionalne 14C starosti.
Antička luka u Zatonu otkrivena je sredinom šezdesetih godina 20. st., a sustavno se istražuje od 2002. god. što nam je omogućilo detaljniji uvid u kronološku problematiku. Vrlo bogati arheološki ...slojevi ne govore samo o privremenoj postaji, nego ukazuju na to da su se brodovi duže zadržavali i da je luka bila značajnije tranzitno pristanište. U luci je pronađena velika količina različitog materijala, uglavnom keramičkih proizvoda, među kojim amfore zauzimaju tek manji dio. U radu se donosi pregled 49 amfora klasificiranih kao tip Forlimpopoli, a za koje se danas najčešće koristi naziv amfore ravnog dna. Autori donose opći pregled istraživanja amfora tipa Forlimpopoli i statističku obradu amfora pronađenih u luci. Amfore su s obzirom na oblik oboda, ručki i dna podijeljene na nekoliko tipova.
Crystal structures of mono- and dinuclear cobalt(II) azido complexes with the condensation product of 2-quinolinecarboxaldehyde and Girard’s T reagent. DFT-BS explanation of ferromagnetic exchange ...coupling in dinuclear Co(II) complex. Magnetic properties of mononuclear Co(II) complex.
Display omitted
A tridentate NNO condensation product of 2-quinolinecarboxaldehyde and Girard’s T reagent (HLCl) in the presence of azide ions coordinates with cobalt(II) giving mononuclear azido Co(II) complex CoHL(N3)3 (1) as a main product and dinuclear end-on azido bridged Co(II) complex Co2L2(μ-1,1-N3)2(N3)2 (2) in traces. Crystal structures of both complexes were determined. Variable temperature magnetic susceptibility measurement studies of complex 1 showed that Co(II) cation is in the low-spin state with t2g6eg1 (S = 1/2) configuration. DFT-BS calculations for complex 2 anticipated ferromagnetic type interaction between paramagnetic centers (J = 53 cm−1).

Display omitted
A dinuclear double end-on azido bridged Ni(II) complex Ni2L2(μ-1,1-N3)2(N3)2 (1) with the condensation product of 2-quinolinecarboxaldehyde and trimethylammonium acetohydrazide chloride (Girard’s T reagent) (HLCl) has been synthesized and characterized by elemental analysis, IR spectroscopy, single-crystal X-ray diffraction, magnetic measurements and DFT studies. In complex 1 intra-dimer ferromagnetic coupling between Ni2+ ions (J=+12.0(2)cm−1) and inter-dimer antiferromagnetic interaction (δ=−0.8(3)cm−1) were observed. DFT-BS calculations provided explanation of ferromagnetic exchange coupling in complex 1.
Two Zn(II) complexes with the condensation product of 2-quinolinecarboxaldehyde and trimethylammonium acetohydrazide chloride (Girard's T reagent) (HLCl) and monodentate pseudohalides (azide and ...cyanate) have been synthesized and characterized by elemental analysis, IR and NMR spectroscopy, and single-crystal X-ray diffraction. In both complexes, the coordination surroundings of the Zn(II) ions consist of a deprotonated hydrazone ligand coordinated through an NNO set of donor atoms and two monodentate pseudohalides (N

The chloro (1) and isocyanato (2) Cd(II) complexes with the condensation product of 2-quinolinecarboxaldehyde and trimethylammonium acetohydrazide chloride (Girard's T reagent) (HLCl) have been ...synthesized and characterized by elemental analysis, IR, and NMR spectroscopy. The crystal structure of chloro Cd(II) complex (1) was determined. In 1 and 2, coordination surrounding of Cd(II) consists of deprotonated hydrazone ligand coordinated through NNO-donor atoms and two monodentates at the rest of the coordination places. Quantum chemical calculations of the molecular structures and the relative stabilities of linkage isomers of the Cd(II) complex showed that the isomer with N-Cd-N coordination of OCN
