Contra-rotating propellers have renewed interest from the naval architecture community, because of the recent development of electric propulsion drives and podded propulsors. Contrarotating propulsion systems have the hydrodynamic advantages of recovering part of the slipstream rotational energy which would otherwise be lost utilizing a conventional screw propeller system. The application of th...

Povzetek. Načrtovalski vzorci so za izkušene načrtovalce nepogrešljivo orodje pri razvoju objektno orientirane programske opreme. Izkušnje, zajete v vzorcih, se preslikujejo v načrt programske opreme skozi realizacijo načrtovalskega vzorca. Realizacija nadgrajuje načrt s spremembami v strukturi objektov in v njihovi medsebojni komunikaciji. Vsi načrtovalski vzorci dopuščajo množico različnih re...

Long-term monitoring is critical to guide conservation strategies and assess the impacts of climatic changes anthropogenic activities. In High Arctic ecosystems, information on distribution population trends plants dramatically lacking. During two field expeditions in 2018 2019, we conducted a systematic floristic survey together with opportunistic collecting polar desert surrounding Alert (Nun...
