Developing Primary Liaison Psychiatric Services for HIV/AIDS Patients in Community

In Indonesia, the number of HIV/AIDS patients has grown at significant level. HIV can be a source of major stress which can lead to changes in mental health, such as persistent sadness, feeling empty and anxiety. The ability of liaison officer could help patients reduce their psychiatric problems and at the same time it can greatly affect patients' risks for transmission of HIV to others. This study aimed to analyze the effect of developing primary liaison psychiatric services for HIV/AIDS patients on the abilities of health care workers to provide treatments. This study used a quasi experimental design with one group pretest-posttest which included 64 health care workers aged between 20 and 50 years from the Community-Integrated Health Care in East Java. The inclusion criteria were nurses and physician in Community-Integrated Health Care. The respondents were assessed using the Abilities of Health Care Workers Checklist pre-treatment and post-treatment. The outcomes were analyzed using the Wilcoxon signed rank test. There was a significant increased in the abilities of health care workers to provide psychiatric services after treatment (p<0.05). The liaison psychiatric services were considered to be effective in increasing the abilities of health care workers in improving the treatment of HIV/AIDS

Effect of van-Hove singularities in single-walled carbon nanotube leads on transport through double quantum dot system

The double quantum dot system with single-walled metallic armchair carbon nanotube leads has been studied using Non-equilibrium Green function in the Keldysh formalism. The effect of relative spacing between the energy levels of the dots, interdot tunneling matrix-element, interdot Coulomb interaction and van-Hove singularities in density of states characteristics of quasi-one-dimensional carbon nanotube leads on the conductance of the double quantum dot system has been studied. The conductance and dot occupancies are calculated at finite temperature. It is observed that the density of states of the carbon nanotube leads play a significant role in determining the conductance profile. In particular, whenever the chemical potential of the isolated double quantum dot system is aligned with the position of a van-Hove singularity in the density of states of armchair carbon nanotube leads, the height of the corresponding conductance peak falls considerably. It is further observed that the suppression in the heights of the alternate peaks depends on the relative positions of the energy levels of the dots and their magnitude of separation.Comment: 16 pages and 16 figure

Breathing Modes in Rotating Bose-Condensed Gas: An Exact Diagonalization Study

We present an exact diagonalization study of the breathing mode collective excitations for a rotating Bose-Einstein condensate of $N=10$ spinless bosons interacting via repulsive finite-range Gaussian potential and harmonically confined in quasi-two-dimension. The yrast state and the low-lying excited states are variationally obtained in given subspaces of the quantized total angular momentum $L$ employing the beyond lowest Landau level approximation in slowly rotating regime with $0 \le L < 2N$. For a given $L$, the low-energy eigenspectra (bands) are obtained in weakly to moderately interacting regime. Further, for a given interaction, the split in low-lying eigenenergies with increasing $L$ is the precursor to spontaneous symmetry breaking of the axisymmetry associated with the entry of the first vortex. With increase in repulsive interaction, the value of the first breathing mode increases for stable total angular momentum states L=0~\mbox{and}~N, but decreases for intermediate $0<L<N$ metastable states. The position of the observed first breathing modes in the eigenspectrum remains unchanged as the interaction is varied over several orders of magnitude.Comment: 5 pages, 3 figures, RevTex two colum
