Insights from two-dimensional mapping of otolith chemistry

Non-destructive microbeam-based methods were used for 2-D mapping of trace elements to gain a greater appreciation of otolith composition and spatial configuration. Based on studies of a wide variety of fish taxa, this approach more fully captures the nature of otolith chemical heterogeneity. Such variations may be due to a number of factors, including differences in crystallization, genetics, gro

Cryogenic hydrogen cooling of heated moderator vessel

In ESS, a pulsed proton beam of 5 MW mean power will hit a tungsten target to generate neutrons by spallation. The pulses are 2.86 ms long and occur with 14 Hz; the power within a pulse is 125 MW. Only centimeters from the target, the neutrons are moderated by liquid hydrogen in aluminium vessels. The deposited power heats the surrounding structures and fluids which are circulated and cooled. The

Lithium analysis using a double-sided silicon strip detector at LIBAF

Quantification and mapping possibilities of lithium in geological material, by Nuclear Reaction Analysis (NRA), was evaluated at the Lund Ion Beam Analysis Facility (LIBAF). LiF and two Standard Reference Materials, (SRM 610 and SRM 612) were used in the investigation. The main part of the data was obtained at the beam energy 635keV studying the high Q-value reaction 7Li(p, α)4He, but reaction yie

Fabrication and analysis of vertical p-type InAs-Si nanowire tunnel FETs

We report InAs-Si nanowire (NW) Tunnel FETs fabricated inside nanotube templates. High device yield and performances are obtained by optimizing the growth conditions and the fabrication flow using inorganic material as dielectric spacer, atomic-layer-deposition for the metal gate and by scaling the equivalent oxide thickness (EOT). We extract the exponential parameter B of Kane's tunneling model f

Intending Engineering Work : A Conceptualisation of Engineers´ Understanding of Innovation through the Encounter with their Own Practice

Innovation is arguably one of the present-day buzzwords pervading economic, social as well as cultural life. The innovation concept however is highly ambiguous. Nevertheless most (positivistic) innovation studies employ seemingly “clear-cut” notions of innovation circumventing its highly elusive nature. These “clear-cut” innovation concepts are built on pre-conceived ontological assumptions. Inter

A Collective Picture of What Makes People Happy: Words Representing Social Relationships, not Money, are Recurrent with the Word ‘Happiness’

The Internet allows people to freely navigate through news and use that information to reinforce or support their own beliefs in, for example, different social networks. In this chapter we suggest that the representation of current predominant views in the news can be seen as collective expressions within a society. Seeing that the notion of what makes individuals happy has been of increasing inte

Proton MR spectroscopy of wild-type and creatine kinase deficient mouse skeletal muscle : dipole-dipole coupling effects and post-mortem changes

Localized proton MR spectra of mouse skeletal muscle obtained at 7 T show dipole-dipole coupling effects for creatine and putative taurine resonances and for the lactate methine signal. These effects are independent of the presence of creatine kinase. The intensity of the methylene (1)H resonance of creatine is not different between wild-type and creatine kinase deficient mice, which have a lower

Synthesis of naproxen-imprinted polymer using Pickering emulsion polymerization

For the last decades, molecular imprinting is developing intensively, especially in the case of the application of new imprinting techniques. In this work, for the first time, a Pickering emulsion polymerization was used to synthesize the S-naproxen-imprinted polymer spheres following a noncovalent protocol. To enhance the knowledge about imprinting process using mentioned technique, thorough anal

Efficiency improvements in an industrial steam turbine stage - Part 2

Improvement in isentropic total to total efficiency of a low reaction turbine stage by airfoil redesign was considered in first part of the paper. Further, modifications in the flow path of the baseline stage is considered in second part of the paper. Flow path of the baseline stage incorporates axisymmetric meridional endwall contour(commonly called Russian kink). For a stage comprising of high a

On Diffusion Transport Properties in Fuel Cell Gas Diffusion Layers Using the Lattice Boltzmann Method

The polymer electrolyte fuel cell (PEFC) is considered as one of the most promising devices for providing efficient, clean and noiseless conversion of chemical energy to electrical energy. This device can provide electrical and thermal energy for transport, mobile and stationary applications ranging in a wide range of power requirements. However, in spite of its promising potential and increasing
