Samverkansbegreppets skiftande betydelse

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

Smallholders’ Demand for and Access to Private Sector Extension Services : A Case Study of Contracted Cotton Producers in Northern Tanzania

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

By Who, for Whom? : Landscape, Process and Economy in the Bloomery Iron Production AD 400-1000

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.

Generation of a human induced pluripotent stem cell line (CSC-40) from a Parkinson's disease patient with a PINK1 p.Q456X mutation

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.

Exciting H2 Molecules for Graphene Functionalization

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

Near ambient pressure X-ray photoelectron - and impedance spectroscopy study of NiO - Ce 0.9 Gd 0.1 O 2-δ anode reduction using a novel dual-chamber spectroelectrochemical cell

This paper reports an experimental study, where the reduction of NiO-GDC to Ni-GDC is monitored using high temperature (HT) near ambient pressure (NAP) X-ray photoelectron spectroscopy (XPS) in combination with simultaneous impedance spectroscopy (IS). The experiment is carried out using a dual chamber (DC)-HT-NAP-XPS cell designed for membrane electrode studies. The dual chamber measurement cell
