Polarized Neutron Matter: A Lowest Order Constrained Variational Approach

In this paper, we calculate some of the polarized neutron matter properties, using the lowest order constrained variational method with the $AV_{18}$ potential and employing a microscopic point of view. A comparison is also made between our results and those of other many-body techniques.Comment: 23 pages, 8 figure

Negotiating identities and emotional belonging: Shan in northern Thailand

This paper explores the complex ways in which Burmese Shan migrants in Northern Thailand utilise strategic practices of in/visibility and in/audibility to maintain emotional attachments to ethnic identity and belonging while negotiating a double exclusion from national belonging and citizenship in both home and host countries. Fleeing Shan State as a result of the long standing civil war and gross human rights abuses by Burma’s military junta, over 200,000 Shan have entered Thailand since 1996. Based on research conducted among three Shan communities in the small town of Pai, this article examines how strategic deployment and concealment of ethnic identity – in/visibility and in/audibility – allows Shan migrants to navigate different spaces of safety and precariousness while located in a situation of permanent temporariness of national (non)belonging

Magnetic fluctuation power near proton temperature anisotropy instability thresholds in the solar wind

The proton temperature anisotropy in the solar wind is known to be constrained by the theoretical thresholds for pressure anisotropy-driven instabilities. Here we use approximately 1 million independent measurements of gyroscale magnetic fluctuations in the solar wind to show for the first time that these fluctuations are enhanced along the temperature anisotropy thresholds of the mirror, proton oblique firehose, and ion cyclotron instabilities. In addition, the measured magnetic compressibility is enhanced at high plasma beta ($\beta_\parallel \gtrsim 1$) along the mirror instability threshold but small elsewhere, consistent with expectations of the mirror mode. The power in this frequency (the 'dissipation') range is often considered to be driven by the solar wind turbulent cascade, an interpretation which should be qualified in light of the present results. In particular, we show that the short wavelength magnetic fluctuation power is a strong function of collisionality, which relaxes the temperature anisotropy away from the instability conditions and reduces correspondingly the fluctuation power.Comment: 4 pages, 4 figure

Dynamic Project Control Utilising a New Approach to Project Control

A new system has been developed for dynamic project management and control known as Planning Orientation Evaluation Methods (POEM) which has been considered as a core project evaluation system incorporating cost and time analysis. The performance control gives the manager a direct influence on the project completion date and rate of spend
