personal samplers or in general blunt body samplers are widely used in occupational hygiene for collecting air contaminants in the work environments. this work is part of an ongoing research into the performance evaluation of personal samplers, particularly in terms of their aerodynamic properties. velocity profiles have been measured around and within typical cylindrical sampling devices, plac...

Background: One of the targets HIV prevention strategy is to ensure that 95% population access services by 2030 with aspiration ending AIDS epidemic 2030. Methods: This a record-based cross-sectional review. Data was extracted from PEP registers and treatment folders January 2017 December 2021. Results: Non-occupational exposure (82.5%) reported more than occupational (17.5%). Majority cases (4...

This study explored the inter-relationships among state and trait anxiety, occupational stress, perfectionism, aspiration, and music performance anxiety in a group of elite operatic chorus artists employed full-time by a national opera company. The chorus artists reported higher trait anxiety, higher occupational role concerns, and higher occupational personal strain than normative samples. Hig...

Students' careers are important in their lives because they will have to make decisions about later life. This study aims examine the key predictors of Career Maturity between Vocational Aspiration and Self-Concept among senior secondary school adolescents. Three measures employed quantitative design, including a self-concept questionnaire developed normed by Saraswat (2011), Occupational Scale...

Computational fluid dynamics was used to investigate particle aspiration efficiency in low-moving air typical of occupational settings (0.1-0.4 m s(-1)). Fluid flow surrounding an inhaling humanoid form and particle trajectories traveling into the mouth were simulated for seven discrete orientations relative to the oncoming wind (0°, 15°, 30°, 60°, 90°, 135° and 180°). Three continuous inhalati...

Adolescents from areas of high deprivation are often assumed to have low aspirations for the future. However, recent research has suggested otherwise and there have been calls for more substantial investigation into the relationship between poverty and aspiration. This article reports levels and variation in aspiration from 1214 adolescents (49.5 % male; 50.5 % female) living in areas of high d...
