Open audiometric reporting standard (OARS)

Minimal reporting standard for reporting hearing outcomes.

Shorter oars are more effective.

The purpose of this investigation was to clarify the effects of blade design and oar length on performance in rowing. Biomechanical models and equations of motion were developed to identify the main forces that affect rowing performance. In addition, the mechanical connection between the propelling blade force and the force that the rower applies on the handle was established. On this basis it ...

Propulsive Efficiency of Rowing Oars

Is the common folklore, that oars are less efficient at propulsion than propellers, correct? Here we examine the propulsive efficiency of the oars used in competitive rowing. We take the propulsive efficiency η of rowing to be the ratio of the energetic benefit, the energy Db dissipated by boat drag, to the energetic cost, the work Wr performed by the rower. Air drag is neglected as is the ener...

Audiometric Configurations in Children

Recent studies suggest that the amplification needs of children and adults differ due to differences in perceptual ability. For example, several studies have confirmed that children realize greater benefit from a more audible speech signal (Stelmachowicz, Hoover, Lewis, Kortekaas and Pittman 2000; Stelmachowicz, Pittman, Hoover, Lewis and Moeller 2004), a higher signal-to-noise ratio (Hall and ...

a standard for the reporting of diagnostic accuracy studies

the most important goal of clinical researches is publishing the results in order to improve human health. if the results will be accepted by the scientific community, researcher aim would be achieved at improving public health. a published article does not guarantee the acceptance of its findings by the scientific community, hence, research should be done by considering a scientific plan. due ...
