Tivat’s urban regeneration-from arsenal to Porto Montenegro by Martinović Ksenija

“…Arsenal employed experienced skilled workers, mostly engineers and craftsmen, and enjoyed an international reputation for a quality ship repair (Radovic, 2015). In 1990’s, the turbulent political and economic situation in ex-Yugoslavia countries and UN sanctions resulted with a decrease of demand and the downfall of Arsenal resulted with decline of Tivat’s economy. …”

Exploring the Complex Heliotail Boundary by an Extended Level Set Approach by C. Onubogu, M. Opher, M. Kornbleuth, G. Tóth, V. Florinski

“…We find that the f _HP = 0 criterion, the standard heliopause definition used by other models to determine where solar wind and interstellar plasma meet, is impacted in the heliotail, where there is a broad mixing region of solar wind and interstellar medium plasma, by the nature of turbulent flows in the heliotail. We explore a different isosurface, defined by f _HP = 0.99, where the interface is composed of 99.5% solar wind and 0.50% interstellar medium. …”
