At the ILC, the overall scheme for a precise measurement of the beam polarisation conists in the usage of two Compton polarimeters per beam (upand downstream of the e+e− interaction point) and a polarisation measurement from annihilation data [1, 2] to set the absolute scale. The two upand downstream polarimeters are complementary, add redundancy and are used to intercalibrate the systems and r...

Recent studies have highlighted a polarisation in the distribution of work during the 1980s, and some have conjectured that this polarisation has been a principal cause of the rise in income inequality. Using data from the British Household Panel Survey, we document the pattern of work polarisation during the first half of the 1990s and show that polarisation was not mainly responsible for inco...

SCIAMACHY (SCanning Imaging Absorption SpectroMeter for Atmospheric CHartographY) is one of the Earth observation research instruments to be included as part of the payload of the ESA (European Space Agency) ENVISAT-1 platform to be launched in the year 2000. The main scientific objective of SCIAMACHY is to measure distributions of a number of chemically important atmospheric trace species on a...

We construct the full linearisation functor which takes a graded bundle of degree k (a particular kind of graded manifold) and produces a k-fold vector bundle. We fully characterise the image of the full linearisation functor and show that we obtain a subcategory of k-fold vector bundles consisting of symmetric k-fold vector bundles equipped with a family of morphisms indexed by the symmetric g...

NMR of the rare earth nuclei in cubic RE-X, compounds has shown that the self polarisation field, Hsp, gives an important contribution to the total hyperfine field at the REnuclei. Both orbital and spin polarisations of the conduction bands arise through anisotropic exchange interaction between the ordered magnetic moments of the rare earth and the conduction electrons. These polarisations are ...

Whilst employment levels in Australia are healthy when compared to those twenty years ago, the available work has become increasingly polarised into either all-work or no-work households. This paper measures the extent of polarisation that has taken place in Australia since 1982 with a measure that accounts for changes in individual based employment and family structure. We find that employment...

This paper describes an accelerated ageing experiment of transformer oil/paper insulation with preset moisture levels. These samples were tested with return voltage and polarisation/depolarisation measurements. Molecular weight has also been measured with Gel Permeation Chromatography (GPC). Results suggested the impact of moisture on the ageing of oil/paper insulation. An attempt has been made...

The spectral behaviour of device 5-90 at a current of 10 mA, well into the multimode regime, is shown in Fig. 3. Even though higherorder modes contain various fractions of both polar&ations, the hndamental mode polarisation is still pinned to the [01 11 crystal direction with a similar suppression ratio as before. This indicates that the polarisation selection mechanism may be strong enough for...

The string-inspired technique is used for the calculation of vacuum polarisation tensors in constant electromagnetic fields. In the first part of this series, we give a detailed exposition of the method for the case of the QED one-loop N-photon amplitude in a general constant electromagnetic background field. The twopoint cases are calculated explicitly, leading to compact representations for t...

We report 17O dynamic nuclear polarisation (DNP) enhanced solid-state NMR experiments at 18.8 T. Several formulations were investigated on the Mg(OH)2 compound. A signal enhancement factor of 17 could be obtained when the solid particles were incorporated into a glassy o-terphenyl matrix doped with BDPA using the Overhauser polarisation transfer scheme whilst the cross effect mechanism enabled ...
