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

The Search for an Artist's Identity : Or how to get lost in the biographies of Isaac Grünewald

I artikeln analyseras historieskrivningen om den svenska konstnären Isaac Grünewald (1889–1946) med särskilt fokus på antisemitiskt grundade föreställningar om honom. Undersökningen utgår huvudsakligen från publicerade biografiska framställningarna som dels beskriver hans karaktär, dels positionerar honom inom den svenska modernistiska konsthistorien. I analyserna lyfts de i materialet återkommand

Ball-and-finger system: modeling and optimal trajectories

A rigid-body model of a finger interacting with a trackball is considered. The proposed system is a suitable candidate for studying trajectory generation when interaction plays an important role, such as in assembly and manipulation tasks. The mathematical model consists of a ball with a spherical joint constraint, a finger with three degrees of freedom, and the Coulomb friction model. From first

Integrating isotopes and documentary evidence : Dietary patterns in a late medieval and early modern mining community, Sweden

This study explores the relationship between dietary patterns and social structure in a pre-industrial mining community in Salberget, Sweden c. 1470 to 1600 A.D. using a combination of different research approaches and tools, including archaeology, osteology, bone chemistry and history.The correlation between demographic criteria (sex and age) and archaeological variables (burial type and burial l

Estimation of conversion coefficients from dose-area product to effective dose for barium meal examinations for adult patients

The aim of the current study was to establish conversion coefficients (CCs) from dose-area product to effective dose for most common barium meal (BM) fluoroscopic examination. The study was based on data collection in two X-ray rooms in a major university hospital in St-Petersburg, Russia that allowed evaluating a structure of BM fluoroscopic examinations and developing a computed model of effecti

Adsorption of NO on Fe3O4(111)

Adsorption of NO on Fe3O4(111) is studied by density functional theory (DFT) calculations. NO is preferably adsorbed atop the octahedral site which has a clearly higher adsorption energy than the tetrahedral site. The difference in adsorption energy correlates with differences in adsorption geometries and N–O stretch vibrations. The results are in good agreement with temperature programmed desorpt
