Turning a Blind Eye: The United States and the Israeli Nuclear Program
( Arie Geronik ) 서울대학교 통일평화연구원 2018 Asian Journal of Peacebuilding Vol.6 No.2
The aim of this paper is to examine the reasoning behind the ongoing U.S. policy of, in effect, ignoring Israel’s nuclear capability. By law, the American administration is obligated to impose sanctions on every country that joins the “Nuclear Club.” Despite this, not only has the United States not imposed sanctions on Israel, but the latter enjoys the lion’s share of U.S. foreign aid. This article tries to follow the logic of this policy. My hypothesis is that by ignoring Israel’s nuclear policy (of ambiguity), the United States can continue to declare her ongoing commitment to the security of Israel, while not having to anchor it in a formal pact. By adopting such a policy, both sides can “have their cake and eat it too.”
Current-induced Spin Wave Excitations in Asymmetric Nanopillar Junctions
Arie Fiandimas,Kyung Jin Lee,Kyung-Ho Shin 한국자기학회 2009 Journal of Magnetics Vol.14 No.2
This study examined the current-induced spin wave excitation in asymmetric nanopillar junctions with a stack sequence of 20 ㎚ Pt/10 ㎚ Cu/7 ㎚ NiFe/300 ㎚ Cu, and a circular lateral dimension of 240 ㎚. An analysis of the magnetic and magnetotransport characteristics of the junction showed a possible spin transfer effect at this sample dimension when the magnetization was switched from a vortex state to another state. This finding is expected to help improve the understanding of the spin transfer torque phenomenon in nanopillar junctions.
Is Public-Private Partnerships (PPP) a Promising Strategy for Rural Development?
Arie Halachmi 연세대학교(미래캠퍼스) 빈곤문제국제개발연구원 2010 地域發展硏究 Vol.19 No.2
Can partnership and contracting out be a promising strategy for enhancing rural development where other methods have failed? Could the private production and delivery of services that used to be performed by government improve public sector productivity? A study of school busing in a rural county in Tennessee (USA) suggests that there is more to Public-Private Partnership (PPP) than what meets the eye. The paper concludes that the special rural context of a PPP can mitigate and change the Principal-Agent nature of the relationships between the partners from a zero sum game kind of a relationship to a collaboration and a win-win game.

Salacca peel-based porous carbon (SPPC) with high surface area (1945 m2 g−1) and large specifc pore volume (1.68 cm3 g−1) was prepared by pre-carbonization and K2CO3 activation method. Based on the TGA results, it can be estimated that up to 70 wt% of sulfur-active materials could be infltrated into the pores of SPPC to form SPPC/S composite cathode for LiS battery. The porous structure of SPPC could act as a bufer layer against volume expansion and minimize the shuttle efect due to the penetration of intermediate polysulfdes during cycle tests. Optimization on sulfur loading (50, 60 and 70 wt%) in SPPCC/S composite was also investigated. It was found that the SPPC/S composites with 60 wt% of sulfur loading had the best electrochemical performances. With 60 wt% of sulfur loading, SPPC/S composite electrodes showed excellent electrochemical performances in terms of high initial specifc discharge capacity of 1006 mAh g−1 at 0.5 C and capacity retention of 71% until the 100th cycle. For both cases of low and high sulfur loading, they caused much worse electrochemical performances. Based on the experimental results, it can be concluded that porous carbons derived from the salacca peel were promising materials for sulfur loading in LiS battery.
