What explains variation in military spending? Conventional wisdom suggests that states arm because of either foreign threats or domestic political institutions. The literature treats these factors as distinct and separate (Nordhaus et. al. 2012, Fordham and Walker 2005, Goldsmith 2003). Less attention is given to how states with different internal constraints respond to similar circumstances. This
In the nondestructive evaluation of concrete structures, ultrasonic techniques are considered to be more capable than low-frequency techniques such as the impact-echo method. This is especially true with the recent development of ultrasonictransducers, synthetic apertures, and results in an image form, and because low-frequency techniques are usually limited intheir evaluation to the frequency of
Det här kapitlet fokuserar på samverkan som begrepp och kulturell företeelse. Även om begreppet samverkan kan ha en lika kortvarig popularitet som sina föregångare kan en kulturhistorisk förståelse för denna företeelse och begrepp bidra till att förstå dess betydelse, möjligheter och begränsningar. En sådan kontextualisering görs i detta kapitel med utgångspunkt i den humanistiska forskningstradit

This paper examines demand for and access to private-sector extension services by contracted cotton producers in northern Tanzania. Data from a non-random survey of 520 smallholders show that only 21.9% received any extension and only 4.6% received extension from the cotton ginnery. Wealthier households were three times more likely to receive extension from any provider. While the public sector re
Landscape, process and economy in the bloomery iron production during AD400–1000 are all integrated in this paper initiated by an archaeological excavation of a bloomery site in Motala in Östergötland, southeast Sweden. This site is one among other contemporaneous sites with similar features, such as long-term iron production and a location in the landscape within easy reach of communication routeLandscape, process and economy in the bloomery iron production during AD 400–1000 are all integrated in this paper initiated by an archaeological exca-vation of a bloomery site in Motala in Östergötland, southeast Sweden.

Parkinson's disease (PD) is a neurodegenerative disease with unknown etiology. Here we show the generation of an induced pluripotent stem cell (iPSC) line, named CSC-40, from dermal fibroblasts obtained from a 59-year-old male patient with a homozygous p.Q456X mutation in the PTEN-induced putative kinase 1 (PINK/PARK6) gene and a confirmed diagnosis of PD, which could be used to model familial PD.
Hydrogen functionalization of graphene by exposure to vibrationally excited H2 molecules is investigated by combined scanning tunneling microscopy, high-resolution electron energy loss spectroscopy, X-ray photoelectron spectroscopy measurements, and density functional theory calculations. The measurements reveal that vibrationally excited H2 molecules dissociatively adsorb on graphene on Ir(111) r
