A considerable number of timber floor masonry structures, typical for construction practices of the late 19th century, were damaged in the earthquake that struck Zagreb on 22 March 2020. Due to the lack of reliable earthquake analyses of this type of structures, it is difficult to estimate the level of risk such buildings are exposed to in the case of design earthquake events. The results of seismic analysis of one such structure are presented in the paper. The analysis is based on displacements and is known as PBD (Performance Based Design). The real necessity, efficiency, and methods for improving seismic response of this type of structures, are discussed.

‘Norths’ distinguishes between the real northern Canada and its imagined north. The frozen north is a symbol of Canada that appears in songs, art, and literature. The actual north is rich in mineral resources, creating phenomena like the Klondike gold rush of the late 19th century. Other regions are rich in oil and natural gas. Fifty per cent of Canada is permafrost, making its landscape particularly vulnerable to climate change. This intensifies old questions about sovereignty, with the world’s Arctic powers engaged in a new gold rush. With shrinking glaciers appearing in both headlines and literature, the landscapes of the real and the imagined north are changing.

The article brings up an obscure episode in the rivalry of the Orthodox and Melkite communities in Syria in the late 19th century. In order to strengthen their superiority over the Orthodox, the Uniates attempted to seize the church of St. George in Izraa, one of the oldest Christian temples in the region. To the Orthodox community it presented a threat coming from a wealthier enemy backed up by the See of Rome and the French embassy. The only ally the Antioch Patriarchate could lean on for support in the fight for its identity was the Russian Empire, a traditional protector of the Orthodox Arabs in the Middle East. The documents from the Foreign Affairs Archive of the Russian Empire, introduced to the scientific usage for the first time, present a unique opportunity to delve into the history of this conflict involving the higher officials of the Ottoman Empire as well as the Russian embassy in ConstantinopleВ статье рассматривается малоизвестный эпизод соперничества православной и Мелкитской общин в Сирии в конце XIX века. Чтобы укрепить свое превосходство над православными, униаты предприняли попытку захватить церковь Святого Георгия в Израа, один из старейших христианских храмов в регионе. Для православной общины он представлял угрозу, исходящую от более богатого врага, поддерживаемого Римским престолом и французским посольством. Единственным союзником, на которого Антиохийский патриархат мог опереться в борьбе за свою идентичность, была Российская Империя, традиционный защитник православных арабов на Ближнем Востоке. Документы из архива иностранных дел Российской Империи, введены в научный оборот впервые, уникальная возможность углубиться в историю этого конфликта с участием высших должностных лиц в Османской империи, а также российского посольства в Константинополе.
