Abstract

Background: Acquired immune deficiency syndrome (AIDS) is a fatal viral disease which can affect the patient’s immune system and render the patient susceptible to opportunistic infections. In recent years, the number of women with HIV acquired through sexual transmission has increased. Therefore, due to the importance of quality of life (QOL) among these women and the impact of violence and social support on their QOL, this study can assist in the recognition of effective factors on QOL of these patients.

Materials and Methods: The study population of this descriptive study consisted of all patients with Human immunodeficiency virus infection/AIDS (HIV/AIDS) who had medical records at the Behavioral Disorders Counseling Center of Shiraz, Iran. To assess QOL, violence, and social support among these patients, the World Health Organization Quality of Life (WHOQOL) scale and the Domestic Violence Questionnaire (DVQ) plus Social Support Questionnaire (SSQ) were used. The collected data were analyzed using Independent two-sample t-test, ANOVA, and correlations.

Results: The QOL and SSQ scores of single individuals were higher compared to other groups and violence was lower in this group. The QOL and SSQ scores of residents of rural areas were lower compared to residents of urban areas. Moreover, the violence score of this group was higher. The QOL and SSQ scores of individuals with higher educational level and better economic status were higher than other groups, but their violence score was lower.

Conclusions: Total mean QOL, violence, and social support scores were assessed in the present study. Based on the correlation found between these variables, it can be concluded that women with HIV/AIDS require more social support so that their QOL, which is one of the main determinants of health, can be improved.

Abstract

Background: Volatile organic compounds (VOC) are considered as major environmental contaminants that have a harmful effect on human and ecosystem health, so much effort has been focused on their removal. The aim of this study was to investigate the removal efficiency of styrene by Zeolite Socony Mobil-5 (ZSM-5) after immobilization of nanoparticles of zinc oxide (ZnO) on it.
Materials and Methods: In this experimental study and in order to produce styrene, clean dry air with a constant flow rate of 1 l/minute was pumped into an impinger containing styrene solution which resulted in the evaporation of styrene. Produced vapors entered into the mixing chamber to be mixed with clean air. Produced styrene with certain concentrations of 20, 100 and 300 ppm was sent to a reactor containing ZSM-5/ZnO bed to investigate the effectiveness of the bed in the elimination of styrene.
Results: This study focused on removal of styrene using ZnO nanoparticles stabilized on ZSM-5 Zeolite. The highest removal efficiency of styrene was 47.5% in concentrations of 20 ppm. For concentrations of 100 and 300 ppm, the efficiency was 22% and 12.5%, respectively.
Conclusions: Both adsorption and catalytic mechanisms can be effective in removal of pollutants in different conditions. Findings related to adsorption and removal of styrene also showed that coating ZnO nanoparticles on zeolite absorbent in presence of ultraviolet (UV) has increased the removal efficiency.
