The author analyzes the emergence and spread of geometric microliths with flat pressing dorsal retouch in the Near and Middle East, in the basin of the Eastern Mediterranean and in Eastern Europe. We consider the typology of these products and their role in the Neolithic complexes of Eastern Europe. Author makes analysis of the typology and technology of geometrics and detected primary and secondary centers of dissemination of new technology.

The news of the accession of Suleiman the Magnificent to the throne of the Ottoman Empire in 1520 did not seriously alarm contemporary European rulers for he was generally considered to be a weakling completely devoid of initiative. Surprisingly, however, this supposedly weak son of a strong father (Selim I) took the initiative within one year of becoming Sultan. Eager to strengthen the position of the Ottoman Empire in Europe, Suleiman temporarily abandoned his father's policy of conquest in the Middle East and launched a series of powerful attacks against South Eastern Europe: Belgrade fell in 1521 after it had withstood Turkish attacks for over half a century; Rhodes, the main Christian stronghold in the Eastern Mediterranean, suffered a similar fate the following year. The pressure on Hungary, which was increased after the fall of Belgrade, discouraged the Eastern Europeans from an optimistic view of their future. Indeed, the outlook for Eastern Europe was by no means bright.

AbstractThis article is a review of Ilham Khuri-Makdisi’s bookThe Eastern Mediterranean and the Making of Global Capitalism, 1860–1914. I argue that this book is a valuable contribution to historiographies of the Left in the Middle East, a field that remains under-represented given the importance of labour to the nationalist movements as well as broader worker-activism in the region throughout the twentieth and twenty-first centuries. I review the main debates of the book, and raise critical questions about aspects that could have been probed further, among them the questions of imperialism and race in contexts such as Egypt and Lebanon, and the relationship(s) between workers and the radical intellectuals discussed throughout the book.


Significance It has yet to win over sceptical member states in southern and Central and Eastern Europe. However, there has been some progress on immigration with countries approving the revised Blue Card Directive which should open more pathways for legal migration. Impacts A fresh spike in illegal migration could have a defining impact on elections in Germany and France. The Eastern Mediterranean will be the most vulnerable route for illegal migration over the coming years. To reduce demand for foreign workers, some EU countries could try to incentivise residents to have more children.

In the studies carried out within the scope of geopolitical discipline, the expression "geography is destiny" is frequently used and it is claimed that geography has unchangeable, irreversible qualities and the policies implemented are shaped through this assumption. This assumption ignores the humanitarian interventions over the geography and makes it difficult to understand the results produced by these interventions at both regional and global level. Similarly, the dynamic nature of international relations reveals new actors in the international system in times of bounce and collapse, and the borders that expand or narrow with each transformation can differentiate the geopolitical view with new sovereign countries. In the historical process, transportation accessibility, trade, search for raw materials, security and alliance relations have caused the same geography to be interpreted differently in different periods. This situation also applies to the geography of Turkey had been the homeland of empires. The developments in the Middle East over the past two decades has created a sensitivity in the relations between Turkey and the West, especially the United States. Competing interests with the EU and the US in the Middle East and the Eastern Mediterranean, has necessitated a reassessment of Turkey's geography.

Abstract To access a larger amount of pay zone, well trajectories are becoming longer and more complex, creating greater challenges for running completion liners. A liner shoe is a casing accessory tool that aids in the running of completion liners in long wells by allowing auto-filling of the liner and enabling pumping through the bottom of the liner. Upon reaching planned liner depth, the liner shoe is closed to allow for pressure testing and subsequent completion operations. Conventional methods used to close a liner shoe involve well intervention to set plugs or by dropping a ball, and there are inherent costs and risks associated with these operations. This paper presents the development and deployment of a remotely activated electronic liner shoe (ELS) for offshore applications that enables interventionless closing of the liner shoe, thereby improving operational efficiency, and reducing potential operational issues that could occur while closing the liner shoe conventionally. The ELS allows the operator to precisely control when the liner shoe closes – either based on pre-programmed pressure signals, a timer, or a combination of the two. A major operator in the Middle East required an ELS to be developed and qualified specifically for their offshore well conditions. A new technology qualification program was devised in collaboration with the operator to qualify both the electronic and mechanical functionalities of the tool. This paper documents the methods and results of the extensive qualification test program. The development and qualification process were successfully completed within 10 months at research and development facilities in Norway. Following qualification testing, the ELS was first deployed for the operator in an offshore well in Q4 of 2019. Operational considerations in programming the remote functionality of the tool is presented in this paper. After a successful field trial, the ELS has been run in more than 15 offshore wells and has become the standard option in the operator's completion program.
