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...

In this paper, validation of a model for the speed dependency of friction is presented. Based on the shape of the friction – speed curve, the model assumes that calculation of friction at any speed would need an estimate of friction at very low speed, and the knowledge of its variation with speed described by the Stribeck curve. Two existing models developed at LCPC are then coupled to predict ...

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.

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 ...

This report provides a review of several measurement studies and campaigns focusing on road dust resuspension (RDS), which is becoming an important source ambient particulate matter (PM) concentrations. There growing requirement from stakeholders, policy makers scientists for gathering additional data around RDS, since there lack well-established methodologies or those developed measuring model...
