Старење бунара у алувијалним срединама различитог степена оксичности
Brankica Majkić (2013-09-27)Старење бунара настаје као последица процеса корозије и колмирања. Процесекорозије могуће је спречити уградњом филтерских конструкција од материјалаотпорних на корозију. Колмирање може да настане без обзира на врсту материјалаод кога се праве бунарске конструкције, а процесом може бити захваћенаприфилтарска зона па и зона саме водоносне средине.

A WordNet Ontology in Improving Searches of Digital Dialect Dictionary
In this paper, we present a method for automatic generation of a digital resource, which connects all indirect synonyms of a dialect term to all indirect synonyms of a corresponding term in the standard language, aiming to improve the search of a digital dialect dictionary. The method uses SWRL rules defined in the Serbian WordNet ontology to identify sets of synonymous words. It also uses e-dictionaries to produce correct lemmas in standard language that users usually employ in searches. ...... и риз т (admit) _/' – д Qo__/ „ 1 ~ пИ imati poverenja (trust) : 7 . „ : р и _ Р и а зупо“ ашогпгоман (ашћог ге) dozvoliti (permit, let) — а /5„,00 ovlastiti (authorize) , 0 ·dozvoliti а55 ~ *0) SV"Onym (р ) Sy?, podneti (endure) Fig. 1.
