We propose a novel interconnector design, termed bi-layer interconnector, for solid oxide fuel cells (SOFCs). It can disturb the fuel gas and air on the planes normal to the SOFC three-phase-boundary (TPB) layer. In this paper, a two-dimensional half-cell model is developed to study the concentration overpotentials in the fuel side of the SOFC stack with conventional and novel bi-layer interconnec

The magnetic field, the sun, the stars and the polarization pattern of visible light during twilight are important cues for orientation in nocturnally migrating songbirds. As these cues change with time and location on Earth, the polarization pattern was put forward as a likely key reference system calibrating the other compass systems. Whether this applies generally to migratory birds is, however

It is shown that the isoscalar strength in the energy region just above the low energy threshold, which is created by exciting particles to the continuum in nuclei far from β-stability lines, can be reduced by the attractive coupling to isoscalar shape oscillations. This is in contrast to the well known fact that in β-stable nuclei low lying isoscalar particle hole strengths are always increased b

To help meet emission standards, hydrogen sulfide (H2S) from geothermal production may be injected back into the subsurface, where basalt offers, in theory, the capacity to mineralize H2S into pyrite. Ensuring the viability of this pollution mitigation technology requires information on how much H2S is mineralized, at what rate and where. To date, monitoring efforts of field-scale H2S reinjection

The accuracy of two clinical assays, the enzyme-multiplied immunoassay (EMIT) and fluorescence polarization immunoassay (FPIA2), universally employed for measurement of plasma levels of methotrexate (MTX) in children administered a high dose of this drug for treatment of acute lymphoblastic leukemia was evaluated here. Because of its superior specificity, sensitivity, and precision, high performan

Mid-infrared polarization spectroscopy (IRPS) and laser-induced fluorescence (IRLIF) have been applied for detection of methane and ethane in atmospheric pressure cold flows and flames. Lines belonging to the asymmetric C-H stretching vibration bands v₃ and v₇ for methane and ethane, respectively, were probed with a tunable infrared laser beam at about 3.4 μm, which was obtai

A Fuel cell is a highly efficient device for converting chemical energy in fuels to electrical energy and the electrical efficiency is strongly affected by the porosity in electrodes due to its close couplings with mass transfer and active sites for the electrochemical reactions, which will also cause changes in distribution of thermal stresses inside the electrodes. A three-dimensional computatio

In this chapter, we discuss threats and emotions as drivers of affective polarization. We base our discussion on Social Identity Theory and Intergroup Threat Theory, with the basic idea that threats posed by other social groups strengthen intergroup differentiation. Drawing on intergroup threat theory, we argue that when individuals perceive an outgroup threatens the ingroup, they will react with

En radar använder elektromagnetiska vågor för att kunna skicka och motta signaler. Precis på samma sätt som att våra öron, ögon och tungor är mottagare och vår röst och vårt kroppsspråk är sändare av signaler till världen omkring oss. För både människan och för radarn så behövs det skydd mot omgivningen. Till exempel, har våra ögon ögonlock och vår röst är dold inne i halsen. Utan ögonlock skulle The radome, a portmanteau of the words radar and dome, is a protective dielectric cover to protect a radar from its surrounding environment. The surrounding environment can be rain, wind, sand, dust and whatever else that might harm the radar. Radomes come in many different shapes, materials and thicknesses, where each of these parameters are decided based on the need for the given radar applicati

This article examines what happens when we listen to E. M. Forster’s A Passage to India (1924), suggesting that sound has several important functions in the novel, which relate both to the conflicts between the different cultural groupings and to the existential questions that underpin the plot. In making a distinction both between eye and ear, and then between hearing and listening, the article a

Many fish species are able to produce sounds, which are often associated with courtship. In an earlier study, we showed for the Lake Victoria cichlid Pundamilia nyererei that females prefer to associate with a male with sound over a male without sound. As a follow-up to this earlier finding, we here investigated whether playback of conspecific sounds is sufficient to attract females in the absence

Although it is widely accepted that honeybees use the polarized-light pattern of the sky as a compass for navigation, there is little direct evidence that this information is actually sensed during flight. Here, we ask whether flying bees can obtain compass cues derived purely from polarized light, and communicate this information to their nest-mates through the 'waggle dance'. Bees, from an obser

The atmospheric profile whose sound speed varies linearly with height is simple in concept, but leads to complications when solving for the sound pressure. Its effects are commonly approximated by a similar profile whose squared refractive index is a linear function of height. In this paper, the validity of the approximation has been examined for sound propagation above an impedance ground and a c

Most heavy-duty engines are diesel operated. Severe emission regulations, high fuel prices, high technology costs (e.g. catalysts, fuel injection systems) and unsustainably in supplying fuel are enough reasons to convenience engine developers to explore alternative technologies or fuels. Using natural gas/biogas can be a very good alternative due to the attractive fuel properties regarding emissio
