U članku je riječ o ranosrednjovjekovnoj križnici sablje ili paloša iz Nina. Autori ju pripisuju Drugom avarskom kaganatu, kojem pripada još desetak nalaza takve vrste oružja s prostora kontinentalne ...Hrvatske. Križnica iz starohrvatske prijestolnice za sada je jedinstven nalaz u Dalmaciji. Otkrivena je 2000. godine u arheološkim istraživanjima ispred pročelja župne crkve sv. Anselma, nekadašnje ninske katedrale.
Brandholzite, a hydrated hydroxide of Mg^sup 2+^ and Sb^sup 5+^ was found at the Kríznica deposit near Pernek (Malé Karpaty Mountains, Slovak Republic); it is the third occurrence of this mineral ...phase worldwide. Crystals and crusts of brandholzite occur as surface coatings on altered shales mineralized with stibnite and pyrite. Associated minerals include roméite-like phases, sulphur, aragonite, gypsum, sénarmontite and Sb-rich Fe-hydroxides. Brandholzite forms euhedral tabular crystals of hexagonal habit, typically 0.5 to 0.8 mm across, exceptionally up to 2 mm long. The crystals occur as isolated, or randomly grouped individuals, creating inconspicuous crusts up to several cm^sup 2^. Brandholzite crystals are colourless, transparent or showing white clouding. No fluorescence was observed under either short- or long-wave UV radiation. The average electron microprobe analysis gave 6.11 MgO, 0.52 CaO, 0.16 FeO, 55.89 Sb^sub 2^O^sub 5^ and (37.32) H2O if recast to 100 wt. %. The calculated formula is (Mg^sub 0.88^Ca^sub 0.05^Fe^sub 0.01^)Σ^sub 0.94^(H2O)^sub 6.00^Sb(OH)^sub 6^^sub 2.00^. The XRD pattern was indexed in a trigonal setting (space group P3), with refined unit-cell parameters a = 16.1076(9), c = 9.8628(9) Angstrom and V = 2216.1(2) Angstrom^sup 3^. The thermogravimetric curve shows total weight loss of 34.6 wt. % (over the interval of 20-800 °C. caused by H2O release. The initial rapid weight decrease (20-140 °C) was followed by a minor continuous weight loss up to 800 °C. Brandholzite from Pernek and its mineral association were probably formed by sub-recent weathering processes in an abandoned mines environment. PUBLICATION ABSTRACT
Razglobiti će se geomorfološke osobine i razvoj korita Drave (108-115 km od ušća) i njenog poloja. Naglasak u radu će biti na morfogenezi poloja i korita tijekom posljednja dva stoljeća, kada su ...izvršeni najznačajniji regulacijski i melioracijski radovi. Uz mlađe tektonske pokrete, ragulacijski i melioracijski radovi su imali velikog utjecaja na izmjenu intenziteta erozijskih i akumulacijskih procesa i na oblikovanje uzdužnog i poprečnog profila vodotoka, te reljefa poloja.
