One pion events by atmospheric neutrinos: A three flavor analysis

We study the one-pion events produced via neutral current (NC) and charged current (CC) interactions by the atmospheric neutrinos. We analyze the ratios of these events in the framework of oscillations between three neutrino flavors. The ratios of the CC events induced by $\nu_e$ to that of the NC events and a similar ratio defined with $\nu_\mu$ help us in distinguishing the different regions of the neutrino parameter space.Comment: 14 pages, 4 figures (separate postscript files

Heat conduction in the \alpha-\beta -Fermi-Pasta-Ulam chain

Recent simulation results on heat conduction in a one-dimensional chain with an asymmetric inter-particle interaction potential and no onsite potential found non-anomalous heat transport in accordance to Fourier's law. This is a surprising result since it was long believed that heat conduction in one-dimensional systems is in general anomalous in the sense that the thermal conductivity diverges as the system size goes to infinity. In this paper we report on detailed numerical simulations of this problem to investigate the possibility of a finite temperature phase transition in this system. Our results indicate that the unexpected results for asymmetric potentials is a result of insufficient chain length, and does not represent the asymptotic behavior.Comment: 14 pages, 6 figure

Testing LSND at long-baseline neutrino experiments

Recently it was suggested that two very different mass-squared differences play a role in atmospheric neutrino oscillations. The larger of these also accounts for the LSND result and the smaller of these also drives the solar neutrino oscillations. We consider the predictions of this scheme for long-baseline experiments. We find that high statistics experiments, such as MINOS, can observe a clean signal for this scheme, which is clearly distinguishable from the usual scheme of atmospheric neutrino oscillations driven by a single mass-squared difference.Comment: 13 pages, 3 figure

Self similar Barkhausen noise in magnetic domain wall motion

A model for domain wall motion in ferromagnets is analyzed. Long-range magnetic dipolar interactions are shown to give rise to self-similar dynamics when the external magnetic field is increased adiabatically. The power spectrum of the resultant Barkhausen noise is of the form $1/\omega^\alpha$, where $\alpha\approx 1.5$ can be estimated from the critical exponents for interface depinning in random media.Comment: 7 pages, RevTex.

Solar Neutrinos and the Eclipse Effect

The solar neutrino counting rate in a real time detector like Super--Kamiokanda, SNO, or Borexino is enhanced due to neutrino oscillations in the Moon during a partial or total solar eclipse. The enhancement is calculated as a function of the neutrino parameters in the case of three flavor mixing. This enhancement, if seen, can further help to determine the neutrino parameters.Comment: 24 Pages Revtex, 8 figures as one ps file. To appear in Phys. Rev.

Empowerment of Women for Improved Quality of Life

Technological developments and information technologies are rapidly changing the economy and lifestyle However women in many developing countries are still deprived of their rights and needs Over the time women in India have faced many problems of inequality and deprivation which have also been a cause of illiteracy and poverty Focused attempt to empower women through sensitization of the community reduction of hardship improved health care development of various skills and support for promoting several income generation activities along with necessary policy support can improve the status of women within 3-5 years even in the backward regions While saving time on their routine household duties and improving the health status of themselves as well as that of their children they have been happy to take up the additional workload for food security and income generation The initial preferences of rural women for income generation were agriculture and livestock husbandry over non-farm activities because of inherent skills and high demand for the produc

SOCIAL WORKERS IN MANAGEMENT: WORK/FAMILY STRESS AND ISSUES OF SELF-CARE

Traditional approaches to stress adopt narrow and individualistic perspective with little attention paid to the wider organisational, social, political and family factors involved. The intersect of all these factors as well as the symptoms of stress that social work managers experienced were examined as part of a broader study of women in management andoccupational stress. The sample consisted of 30 women managers from diverse racial backgrounds. Ten of these managers were social workers. Both private and public organisations with local, national and international status were included in this study. Data were obtained through the use of a biographical questionnaire, a semi-structured interview schedule, the Type A personality scale and the 'Identifying stress at work' scale.  Organisational contributors to occupational stress have been identified as follows: logistical constraints, career development, relationships at work, role in organisation, organisational structure and extra-organisational forces. The social factors, which impacted on the social work manager's experience of stress, were racism and gender discrimination. All the social work managers displayed Type A behaviour. The following sources of stress at the work/family interface were identified: domestic pressures, parental stress, marital discord, bi-cultural role conflict, and spill-over of job/stress into family life. Social work managers displayed physical, psychological and behavioural symptoms of stress.  The social work managers used a variety of strategies to cope with pressure and combat stress.  Given the nature of the stressors experienced by the social work managers, organisational as well as individual interventions to enhance self-care are recommended
