Observable to explore high density behaviour of symmetry energy

We aim to see the sensitivity of collective transverse in-plane flow to symmetry energy at low as well as high densities and also to see the effect of different density dependencies of symmetry energy on the same.Comment: 3 pages, 2 figs, DAE BRNS Symposium on Nuclear Physics Dec 26-30, (2011), Visakhapatnam A.P.

Effect of isospin dependence of cross section on symmetric and neutron rich systems

We aim to explore the effect of isospin dependence of cross section on symmetric and neutron rich system. We also aim to explore whether the analysis is affacted if one discusses in terms of "$E_{bal}$ as a function of N/Z or N/A" of the system.Comment: 3 pages, 1 figs, DAE BRNS Symposium on Nuclear Physics Dec 26-30, (2011), Visakhapatnam A.P.

Why are there still so few men within Early Years in primary schools: views from male trainee teachers and male leaders?

One of the challenges facing the Early Years (EY) sector is how to encourage more male practitioners to counterbalance a largely feminised workforce. Using case studies of male trainees at different stages of their primary undergraduate Initial Teacher Training course at one university, we attempt to consider data why there is underrepresentation of men within the leadership strata in EY settings. Questionnaires and interviews were conducted with the male sample groups and male leaders in primary schools to gain an overview regarding gender stereotyping. Our findings suggest that male trainees enjoy working in the EY sector, but they need mentoring by strong leaders to help them overcome the perceived contextual barriers of male stereotypes in that setting. In conclusion, we consider some of these barriers of stereotypes, attitudes, values, beliefs existing and the actions needed in addressing such stereotypes if a long-lasting change is to happen

Model ingredients and peak mass production in heavy-ion collisions

We simulate the central reactions of $^{20}$Ne+$^{20}$Ne, $^{40}$Ar+$^{45}$Sc, $^{58}$Ni+$^{58}$Ni, $^{86}$Kr+$^{93}$Nb, $^{129}$Xe+$^{118}$Sn, $^{86}$Kr+$^{197}$Au, and $^{197}$Au+$^{197}$Au at different incident energies for different equations of state, different binary cross sections and different widths of Gaussians. A rise-and-fall behavior of the multiplicity of intermediate mass fragments (IMFs) is observed. The system size dependence of peak center-of-mass energy E$_{c.m.} ^{max}$ and peak IMF multiplicity $^{max}$ is also studied, where it is observed that E$_{c.m.}^{max}$ follows a linear behavior and $^{max}$ shows a power-law dependence. A comparison between two clusterization methods, the minimum spanning tree and the minimum spanning tree method with binding energy check (MSTB), is also made. We find that the MSTB method reduces the $^{max}$, especially in heavy systems. The power-law dependence is also observed for fragments of different sizes at E$_{c.m.} ^{max}$ and the power-law parameter $\tau$ is found to be close to unity in all cases except A$^{max}$.Comment: 6 Figures, 7 page

Geometry of vanishing flow: a new probe to determine the in-medium nucleon nucleon cross-section

We study the transverse flow throughout the mass range from $^{20}Ne+^{20}Ne$ to $^{131}Xe+^{131}Xe$ as a function of the impact parameter. We find that at smaller impact parameters the flow is negative while going through the impact parameter, transverse flow vanishes at a particular colliding geometry named GVF. We find that the mass dependence of GVF is insensitive to the equation of state and momentum dependent interactions whereas it is quite sensitive to the cross section. So it can act as a useful tool to pin down the nucleon nucleon cross section

A mosaic infrared sensor for space astronomy, phase 3

Short wavelength (1 to 3 micron) HgCdTe mosaic detector arrays for space astronomy purposes were fabricated and studied. Honeywell will test and analyze these arrays at moderate temperatures (300-130K). Low temperature testing will be performed at the University of Hawaii. Short wavelength mosaic arrays were fabricated on three wafers and one array from each wafer was tested and analyzed. The p-type base carrier concentration on these wafers was an order of magnitude lower than typically used so far on this program (10 to the 14/cc as compared to 10 to the 15/cc). Tunneling currents are expected to decrease with this decrease in carrier concentration, resulting in improved performance at very low temperatures. The risk with such a low carrier concentration is that fixed charge in the surface passivating layer must be carefully controlled to prevent surface inversion layers
