Review of AdS/CFT Integrability: An Overview
This is the introductory chapter of a review collection on integrability in
the context of the AdS/CFT correspondence. In the collection we present an
overview of the achievements and the status of this subject as of the year

Spiky Strings in AdS(4) X CP**3 with Neveu-Schwarz Flux
We study general rotating string solution in the AdS(4) X CP**3 background
with a B_NS holonomy turned on over . We
find the giant magnon and single spike solutions for the string moving in this
background corresponding to open spin chain. We calculate the corresponding
dispersion relation among various conserved charges for both the cases. We
further study the finite size effect on both the giant magnon and single spike
solutions.Comment: 12 pages,Minor modification,Published Version in JHE
The Obama Administration’s First Year and IHL: A Pragmatist Reclaims the High Ground
In a list of ‘desk side reminders’, allegedly originating with General Colin Powell, there is one towards the end which says ‘the window for changes is the first year’. It is unlikely President Obama follows these reminders, but it is nonetheless worthwhile to consider how his decisions – the decisions of the Commander in Chief of the sole remaining military superpower – impacted the application and development of international humanitarian law during the year when his window of opportunity was open. President Obama\u27s first year in office can be defined by two words: pragmatism and commitment. His pragmatism is reflected in the decision to continue to pursue the armed conflicts against transnational terrorism, and his refusal to abandon the legal and policy positions of his predecessor that lodge that struggle squarely within an armed conflict paradigm. His commitment is reflected both in his decision to continue the armed struggle against transnational terrorism, and in the actions he has taken to demonstrate US commitment to fundamental humanitarian principles of the law, and to abandon the policy of legal exceptionalism that defined his predecessor\u27s ‘authority without obligation’ interpretation of the law as it applied to this armed conflict. Any doubt about these dual pillars of his approach to transnational terrorism was eliminated when he delivered his Nobel acceptance speech. In that speech, he challenged the international community to accept the continuing need to meet the threat of transnational terrorism with military force. However, he also emphasized that maintaining the moral high ground in the conduct of hostilities – even when confronting an immoral opponent – is at the very core of the American military tradition. This essay will review what the authors consider the President’s most significant humanitarian law related decisions during his first year in office. It will focus on six major aspects of international humanitarian law: 1) the definition of enemy combatant; 2) detainee judicial review; 3) military commissions; 4) self help measures in self-defense; 5) fundamental guarantees under customary international law; and 6) the US position vis a vis the International Criminal Court
International, Collaborative and Online Education of LIS-students – A Step to the Future?
In this paper, we will analyze and discuss the quality of a project course with an international, collaborative and online format, whose content touches all Swiss information literacy standards. The analysis on a micro-level shall illuminate if the course setup can be declared as a more comprehensive teaching method for LIS students, than the simple teacher- or classroom centered education
The Graduating European Dentist: Contemporaneous Methods of Teaching, Learning and Assessment in Dental Undergraduate Education
It is often the case that good teachers just “intuitively” know how to teach. Whilst that may be true, there is now a greater need to understand the various processes that underpin both the ways in which a curriculum is delivered, and the way in which the students engage with learning; curricula need to be designed to meet the changing needs of our new graduates, providing new, and robust learning opportunities, and be communicated effectively to both staff and students. The aim of this document is to draw together robust and contemporaneous methods of teaching, learning and assessment that help to overcome some of the more traditional barriers within dental undergraduate programmes. The methods have been chosen to map specifically to The Graduating European Dentist, and should be considered in parallel with the benchmarking process that educators and institutions employ locally. © 2017 John Wiley & Sons A/S.

Experimental study of phase equilibria in the PbO-ZnO-"Fe2O3"-(CaO+SiO2) system in air for the lead and zinc blast furnace sinters (CaO/SiO2 weight ratio of 0.933 and PbO/(CaO+SiO2) ratios of 2.0 and 3.2)
Experimental studies on phase equilibria and liquidus in the multicomponent system PbO-ZnO-CaO-SiO2-FeO-Fe2O3 in air have been conducted over the temperature range between 1323 K (1050 degreesC) and 1623 K (1350 degreesC) to characterize the phase relations of the complex slag systems encountered in lead and zinc blast furnace sinters. The liquidus in two pseudoternary sections ZnO-Fe2O3-(PbO + CaO + SiO2) with the CaO/SiO2 weight ratio of 0.933 and PbO/(CaO + SiO2) weight ratios of 2.0 and 3.2 have been constructed
