Polypharmacy has now increasingly come into focus as the recipient of healthcare in old age worldwide. In elderly it is associated with frequent adverse drug reactions (ADRs) and drug-drug interactions resulting in significant morbidity. Geriatrics is still an emerging specialty in South Asia, especially in Pakistan, where multiple reasons for polypharmacy exist. An extensive literature review ...

Analyses of the effects of service conditions on the distribution of residual stresses in railroad commuter car wheels are presented. Novel software has been applied to estimate the effects of service conditions on the as-manufactured state of these wheels. Contact loads resulting from wheel and rail interaction and thermal loads from on-tread braking are considered. Results indicate that conta...

The purpose of this study was to examine the effects of load carrying methods, stair slopes and walking speeds on heart rate and walking postures. Nine participants climbed up and down stairs with various stair slopes (24°, 30° and 36°), walking speeds (72, 96, and 132 steps per minute), and using different load carrying methods (empty loads, backpack, and hand-held). The effects of these facto...

Real-time databases have numerous applications, including commodities trading, military command and control, patient monitoring, air tra c control, and exible manufacturing. All of these applications require that data be processed in such a way that the data and output of the database remains logically consistent . They also require that deadlines imposed on database operations are met (tempora...

The article considers and calculates the brake system of a two-axle service diesel motor car, consisting two subsystems acting separately on axles provided that each axle is served by one cylinder 501b. A calculation was made in order to evaluate effectiveness friction tread car model AS-01uz.

afinite element model of a bias truck tire under static vertical load using a global/local technique is designed in two parts. in the first part a previously created model for radial tires is developed to take the constructional variables of bias tires into account. it is shown that the technique can successfully be used for bias tires. the main challenge here is the selection of the initial la...

We have measured the surface topography and calculated the surface roughness power spectrum for an asphalt road surface. For the same surface we have measured the friction for a tire tread compound for velocities 10(-6) m s(-1) < v < 10(-3) m s(-1) at three different temperatures (at -8 °C, 20 °C and 48 °C). The friction data was shifted using the bulk viscoelasticity shift factor a(T) to form ...

Slips and falls are among the most serious public safety hazards. Adequate friction at shoe–floor contact is necessary to reduce these risks. In presence of slippery fluids such as water or oil, footwear outsole crucial for ensuring appropriate traction. While influence flooring contaminants on traction has been extensively studied across several surfaces, limited studies have investigated scie...
