Tank gauging apparatus and method

An apparatus for gauging the amount of liquid in a container of liquid and gas under low or zero gravity net conditions includes an accumulator and appropriate connector apparatus for communicating gas between the accumulator and the container. In one form of the invention, gas is removed from the container and compressed into the accumulator. The pressure and temperature of the fluid in the container is measured before and after removal of the gas; the pressure and temperature of the gas in the accumulator is measured before and after compression of the gas into the accumulator from the container. These pressure and temperature measurements are used to determine the volume of gas in the container, whereby the volume of the liquid in the container can be determined from the difference between the known volume of the container and the volume of gas in the container. Gas from the accumulator may be communicated into the container in a similar process as a verification of the gauging of the liquid volume, or as an independent process for determining the volume of liquid in the container

Migrant workers in Liverpool: A study of A8 and A2 nationals

This study focuses on the needs and experiences of Central and Eastern European migrants living and working in Liverpool. It was funded by Liverpool City Council and formed the evidence base for their successful application for Migration Impact Funding

Distribution and size of elements of Saturn's rings as inferred from 12-cm radar observations

A 64m radar antenna was used to observe Saturn's rings at 12.6 cm wavelength, with reduced Doppler spread. The results show a positive radar return corresponding to about a 60 percent return from an isotropic scatterer with the projected area of the rings, allowing for the Cassini division. A radar spectrogram of the rings is shown with power density plotted against Doppler frequency shift

Gaussian potentials facilitate access to quantum Hall states in rotating Bose gases

Through exact numerical diagonalization for small numbers of atoms, we show that it is possible to access quantum Hall states in harmonically confined Bose gases at rotation frequencies well below the centrifugal limit by applying a repulsive Gaussian potential at the trap center. The main idea is to reduce or eliminate the effective trapping frequency in regions where the particle density is appreciable. The critical rotation frequency required to obtain the bosonic Laughlin state can be fixed at an experimentally accessible value by choosing an applied Gaussian whose amplitude increases linearly with the number of atoms while its width increases as the square root.Comment: 4 pages, 4 figure

A study of A8 and A2 migrants in Nottingham

The research was commissioned by Nottingham City Council and One Nottingham in August 2008 and was conducted by a team of researchers from the Salford Housing & Urban Studies Unit at the University of Salford. The study was greatly aided by research support from Nottingham City Council Children’s Services Asylum Seeker/Refugee Support Team, as well as a number of community interviewers. The project was managed by a steering group composed of officers representing Nottingham City Council, One Nottingham, Nottingham City Homes, NHS Nottingham City, Nottinghamshire Fire & Rescue Service, Nottinghamshire Police and Basic Educational Guidance in Nottinghamshire (BEGIN). The main objective of this research was to explore the needs and experiences of A8 and A2 migrants living and working in Nottingham
