The torso cooling of vests incorporated with phase change materials: a sweat evaporation perspective

Cooling vests incorporated with phase change materials (PCMs) add extra insulation and restrict sweat evaporation. It is still unclear how much cooling benefit they can provide. The aim of this study was to investigate the torso cooling of the PCM vests in two hot environments: hot humid (HH, 34C, 75% relative humidity (RH)) and hot dry (HD, 34C, 37% RH). A pre-wetted torso fabric skin was used to

Studies of the performance of the ATLAS detector using cosmic-ray muons

Muons from cosmic-ray interactions in the atmosphere provide a high-statistics source of particles that can be used to study the performance and calibration of the ATLAS detector. Cosmic-ray muons can penetrate to the cavern and deposit energy in all detector subsystems. Such events have played an important role in the commissioning of the detector since the start of the installation phase in 2005

Structural Characterisation of GaP <111 > B Nanowires by HRTEM

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

Introduction to special issue on learning, innovation systems and policy in honour of Bengt-Ake Lundvall

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

A compact multifunctional microfluidic platform for exploring cellular dynamics in real-time using electrochemical detection

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 HCN measurements in CH4/N2O/O-2/N-2 flames using mid-infrared polarization spectroscopy

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

Design and test of a broadband split-and-delay unit for attosecond XUV-XUV pump-probe experiments.

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

Defining a Framework for the Development of ICT Services “Nearshoring” in Portugal

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: processing FLAMES-UVES spectra

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

The construction of organizational identity: Comparative case studies of consulting firms

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

Leetocracy : Political participation, social network sites and inequality

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

Definitions, Epidemiology, Clinical Presentation and Prognosis

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
