GaP < 111 > B nanowires are dominated by (111) twins orthogonal to the growth direction and show well-developed {111} side-facets. Based on this, a 3D-model has been constructed with a cross-section of an octahedron used as a building block. The twins can be of ortho- or para type i.e. by 60 degrees about the growth axis or 180 degrees in the twin plane. The segment thickness variation follows an
This special issue celebrates the work of Bengt-Ake Lundvall on his 70th birthday. In the 1980s and 1990s he was a key player among a small group of academics in the USA and Europe that developed a new, systemic approach to the study of the interactions between science, innovation, and policy. He contributed to the popularity of the approach in the policy community in several ways, among other thi
Downscaling of microfluidic cell culture and detection devices for electrochemical monitoring has mostly focused on miniaturization of the microfluidic chips which are often designed for specific applications and therefore lack functional flexibility. We present a compact microfluidic cell culture and electrochemical analysis platform with in-built fluid handling and detection, enabling complete c
Quantitative measurements of hydrogen cyanide (HCN) were nonintrusively performed using mid-infrared polarization spectroscopy (IRPS) in atmospheric pressure flames. The lifted flat, laminar, premixed CH4/N2O/O-2/N-2 flames were stabilized on a 7 cm diameter home-built McKenna-type burner with variable proportion of N2O and O-2. The characteristic spectral structure of HCN molecules was identified
We present the design of a split-and-delay unit for the production of two delayed replicas of an incident extreme ultraviolet (XUV) pulse. The device features a single grazing incidence reflection in combination with attenuation of remaining infrared light co-propagating with the XUV beam, offering a high throughput without the need of introducing additional optics that would further decrease the
This paper presents a framework for policies development enabling growth of Nearshore in information and communications technologies (ICT) services inside European Community (EC), which are based in Portuguese companies, emphasizing what is needed to explore the huge opportunity to develop exportations, employability and the national economy. In a market of ICTs Outsourcing services forecasted in
The Gaia-ESO Survey is a large public spectroscopic survey that aims to derive radial velocities and fundamental parameters of about 10(5) Milky Way stars in the field and in clusters. Observations are carried out with the multi-object optical spectrograph FLAMES, using simultaneously the medium-resolution (R similar to 20 000) GIRAFFE spectrograph and the high-resolution (R similar to 47 000) UVE
This paper explores how organizational identity is constructed in four very different management consulting firms. The study suggests four broad dimensions that organizational members refer to in constructing their organizational identity: Knowledge Work, Management and Membership, Personal Orientation, and External Interface. We identify multiple themes within these broad dimensions of identity c
Popular Abstract in Swedish Kan sociala nätverkssajter eller sociala medier som Facebook och Twitter göra att det politiska deltagandet i samhället blir med jämlikt - både med avseende på vilka personer som deltar och med avseende på hur själva engagemanget organiseras? Denna avhandling innehåller sex artiklar som studerar detta med tyngdpunkt på politiskt deltagande i Sverige, samt en introduktioThis dissertation is about whether social network sites have the potential to bring about more equal participation. It deals with a phenomenon that has changed the underlying infrastructure of how millions of people communicate. It studies the way the use of social network sites affects communication within existing political organisations in addition to networked campaigns. And it goes beyond dig
The concept of chronic critical limb ischaemia (CLI) emerged late in the history of peripheral arterial occlusive disease (PAOD). The historical background and changing definitions of CLI over the last decades are important to know in order to understand why epidemiologic data are so difficult to compare between articles and over time. The prevalence of CLI is probably very high and largely undere
Folding of the Protein G B1 domain (PGB1) shifts with increasing salt concentration from a cooperative assembly of inherently unstructured subdomains to an assembly of partly pre-folded structures. The salt-dependence of pre-folding contributes to the stability minimum observed at physiological salt conditions. Our conclusions are based on a study in which the reconstitution of PGB1 from two fragm
