Are skin disorders related to work strain in hospital workers? A cross-sectional study

To evaluate whether occupational stress factors (high demands, low control, low social support, strain, and iso-strain) are associated with skin disorders in hospital workers and whether psychological problems, such as anxiety and depression, act as potential mechanisms through which occupational stress factors are associated with skin disorders

Rotordynamic modelling and analysis of a radial inflow turbine rotor-bearing system

One of the challenging aspects of radial turbine design and manufacturing is vibration and stability. Rotordynamic analysis was performed on a rotor-bearing system of a 1 kWe radial inflow turbine. The objective of rotordynamic analysis is to determine suitable system configuration for stable operation in the design process. The rotor and blade design were previously developed using ANSYS Structural module which provides the mass and inertia of the complex blade geometry for the rotordynamic analysis. A simulation model with concentrated mass and inertia was built for the rotating structure using ANSYS Parametric Design Language (APDL). Modal and mass unbalance response analyses were carried out with six cases having different shaft diameters and bearing arrangements. The best case was chosen for further parametric study of the effects of shaft length, blade residual unbalance, and bearing stiffness on the blade displacement amplitude. Blade clearance was then set to determine acceptable shaft length, bearing arrangement, blade unbalance quality, and bearing stiffness

Age-Based Simulation of Merging Behavior at Freeway Merging Ramps

In this research, VISSIM, a microscopic traffic simulation software, was used to evaluate the influence of drivers\u27 age on the operations of a typical diamond interchange. Data were collected on two merging sections along I-75 in Southwest Florida at free-flow traffic condition to get enough samples for driver\u27s age group. Several measures of effectiveness were collected, including speeds, gaps, and location of entry to the main-line lanes. This information was used as either model input or for verification purposes in the validation process. Two VISSIM models were developed for each site: One model for the existing conditions and verification and another model for a sensitivity analysis, varying the percentage of older drivers and level of service (LOS from A to E) to determine their influence on ramp merging operational characteristics. At 95% confidence level, the results indicate that merging speed is a significant factor influencing the merging location. Older drivers have low merging speeds compared with middle-age and younger drivers. The changes in LOS were found to influence the selection of the merging location for all drivers, whereby at LOS E, most drivers tend to merge near the end of the acceleration lane
