AbstractGenus Neosinocythere is described from the upper Miocene Itahana Formation in Central Japan, documenting the first record from Japan. The Neosinocythere species were discovered in gravity-flow sediments that were deposited below a depth of 84.9 m with a paleo-summer bottom temperature of 23.7°C and a paleo-winter bottom temperature of 14.1°C, based on a modern analog technique using the ostracode assemblage. Paleobiogeographical and paleoenvironmental analyses indicate that Neosinocythere appeared around the southeastern coast of the Eurasian continent, extended distribution in the northern coast of the Eurasian continent before migrating southward along the coast of the Eurasian continent as global temperatures decreased. The high-diversity area shifted from high latitudes to low latitudes.

Oxygen transfer to water in gravity flow pipes has been studied in a 24 m long, 0.225 m diameter sewer. Laboratory tests were conducted where the slope and flow in the sewer could be varied independently. The clean water reaeration test was used to determine the oxygen transfer. The KL value for the oxygen transfer was found to be a function of energy dissipation and mean hydraulic depth. The results are discussed in relation to oxygen transfer determinations in flumes and field studies of oxygen transfer in sewers.

This chapter analyses the adaptation of Poland’s defence policy and armed forces to the rapidly changing security environment along NATO’s north-eastern flank. First, it examines the impact of a resurgent Russia on Poland’s security calculus, especially since Russia’s seizure of Crimea and the war in eastern Ukraine. Next, it addresses the evolution of Warsaw’s views on the relative utility of NATO and the European Union and its efforts to return NATO to its traditional territorial defence role. It then focuses on the modernization of Poland’s armed forces, with a special emphasis on doctrinal change, the reform of the command and control system, and the creation of the Territorial Defence units. It also reviews the t state of key hardware purchases as of mid-2017. The chapter concludes with an overall assessment of the level of capabilities and the readiness of the armed forces in the changing threat environment along NATO’s north-eastern flank.
