As maloclusões são defeitos ósseos e/ou dentários que ocasionam encaixe incorreto entre os dentes da arcada superior com inferior. O diagnóstico quando realizado ainda na fase de crescimento apresenta-se uma maior taxa sucesso, vez o das bases ósseas não está consolidado e tratamento ortodôntico interceptativo se mostra eficaz. Entretanto, apenas diagnosticado adulta paciente necessita ser subm...

The paper compared the effect of additives such as FeSO4.7H2O and SnCl2.2H2O on reduction of water soluble Cr(VI), in ordinary Portland cement (43 grades). The determination of water soluble Cr(VI) from cement samples was precisely conducted by DPC-Spectrophotometer technique. The compressive strength testing of the cement mortar samples was carried out. In addition, hydration properties of cem...

The tin(IV) atom in the complex anion of the title salt, (C4H7N2)[Sn(C2O4)Cl3(H2O)], is in a distorted octa-hedral coordination environment defined by three chlorido ligands, an oxygen atom from a water mol-ecule and two oxygen atoms from a chelating oxalate anion. The organic cation is linked through a bifurcated N-H⋯O hydrogen bond to the free oxygen atoms of the oxalate ligand of the complex...

In the structure of the hydrated title salt, (C4H7N2)2[Sn(C2O4)2(OH)2]·H2O, the asymmetric unit comprises one stannate(IV) dianion, two organic cations and one water mol-ecule of crystallization. The [Sn(C2O4)2(OH)2](2-) dianion consists of an Sn(IV) atom chelated by two oxalate anions and coordinated by two OH(-) ligands in a cis octa-hedral arrangement. Neighbouring anions are connected throu...

The first charge-neutral Lewis base adducts of tin(IV) tetraazide, [Sn(N3)4(bpy)], [Sn(N3)4(phen)] and [Sn(N3)4(py)2], and the salt bis{bis(triphenylphosphine)iminium} hexa(azido)stannate [(PPN)2Sn(N3)6] (bpy = 2,2'-bipyridine; phen = 1,10-phenanthroline; py = pyridine; PPN = N(PPh3)2) have been prepared using covalent or ionic azide-transfer reagents and ligand-exchange reactions. The azides w...

Penelitian ini bertujuan untuk mengetahui aktivitas fotokatalitik TiO2 yang disintesis dalam cairan ion 1-buti-3-metil imidzalium tetrafloroborat terhadap degradasi asam humat. Prekursor digunakan penelitian adalah TEOT (Tetra Etil Orto Titanat). Sintesis dilakukan dengan metode hidrotermal menggunakan sebagai pelarut perbandingan BMIM BF4 : air (3:7v/v). Berdasarkan hasil XRD diperoleh bahwa (...

Prevalencija poremećaja hranjenja u mladih ljudi stalnom je porastu, što dovodi fokus ortoreksiju nervozu, osobito razdobljima pandemije i stresa. Stoga cilj ovog istraživanja bio utvrditi prevalenciju ortoreksije nervoze povezati s antropometrijskim parametrima, prehrambenim navikama percepcijom tjelesnog izgleda. Ovo istraživanje uključivalo 191 ispitanika dobi od 18-24 godine, čega 85,9 % že...
