The European Union (EU) has played an important, yet inconsistent role in the Israel-Palestine conflict since the1980 Venice Declaration. This paper analyses how the EU’s role as a mediator has changed more recently in the Israel-Gaza conflict. Specifically, it examines how the ‘Concept on Strengthening EU Mediation and Dialogue Capacities’ adopted in 2009 and the creation of the European External Action Service and the High Representative by the Lisbon Treaty have changed the EU’s resources and strategies as a mediator as well as how these developments improved cooperation and coordination with other mediators. This analysis is done through a comparison of the EU’s role in the Israeli Operation Cast Lead in 2008/2009 and Operation Protective Edge in 2014. It is argued that the aforementioned changes made the EU a more capable mediator and facilitated internal coordination. However, these changes did not create more resources for the EU as a mediator, rather they changed how the EU used its resources.

The setting up of a Special Operations Command (SOCOM) constitutes a key element of the ongoing Belgian defence reforms. This Policy Brief aims to put the present demand for special operations forces in its historical context and engage in the discussion on how to structure and employ this special instrument of policy. Building on the legacy of the paracommando regiment, the future Belgian SOCOM constitutes a critical capability within an adaptive force structure. This new entity must be able to deliver results in a variety of unconventional missions that require high readiness, intellectual flexibility and maximum discretion or surprise. At the same time, special operations forces do not constitute a substitute for having a comprehensive security policy. They function best when used as force multipliers alongside other instruments of power towards joint effect. As the proverbial tip of the spear, they must lead the way for Belgian defence regeneration in general.

Article is devoted to design of optimum electromagnets for magnetic levitation of transport systems. The method of electromagnets design based on the inverse problem solution of electrical equipment is offered. The method differs from known by introducing a stage of minimization the target functions providing the stated levitation force and magnetic induction in a gap, and also the mass of an electromagnet. Initial values of parameters are received, using approximate formulas of the theory of electric devices and electrical equipment. The example of realization of a method is given. The received results show its high efficiency at design. It is practical to use the offered method and the computer program realizing it as a part of system of the automated design of electric equipment for transport with a magnetic levitation.

Distribution of diatoms, radiolarians, planktonic and benthic foraminifers, and sediment components in fraction >0.125 mm was analyzed in a core obtained from the central Sea of Okhotsk within frameworks of the Russian-German KOMEX Project. The core section characterizes the period 190-350 ka, which corresponds to marine-isotopic stages (MIS) 7 to 10. During glacial MIS 10 and MIS 8, the basin accumulated terrigenous material lacking microfossils or containing them in low abundance, which reflects, along with their composition, heavy sea-ice conditions, suppressed bioproductivity, and bottom environment aggressive toward calcium carbonate. Interglacial MIS 9 was characterized by elevated bioproductivity with accumulation of diatomaceous ooze during the climatic optimum (328 to 320 ka). Water exchange with the Pacific was maximal from 328 to 324 ka ago. Environment became moderate and close to the present-day one at the end of the optimum exhibiting possible existence of a dichothermal layer with substantial amounts of surface Pacific water still flowing into the basin. Similar to interglacial MIS 5e and MIS 1, ''old'' Pacific water determined near-bottom environment in the central Sea of Okhotsk during that period, although influx of terrigenous material was higher, probably reflecting more humid climate of the region. Slight warming marked the terminal MIS 8 (approximately 260 ka ago). Paleoceanographic situation during the interglacial MIS 7 was highly variable: from warm-water to almost glacial. The main climatic optimum of MIS 7 occurred within 220-210 ka, when subsurface stratification increased and the dichothermal layer developed. Bottom environment during the studied time interval, except for the optimum of interglacial MIS 9, resembled those characteristic of glacial periods: actively formed ''young'' Okhotsk water displaced ''old'' Pacific deep water.
