Long-term memory for position was examined from the perspective of an immediate memory framework, the perturbation model of Estes (Estes, 1972; Lee & Estes, 1977, 1981). First, a simple version of the perturbation model is shown to provide a reasonable fit of previously reported long-term data (Nairne, 1990b), even though the perturbation idea was developed to explain the phenomena of immediate...

BACKGROUND Electrocardiogram (ECG) is a cost effective tool to evaluate left ventricular hypertrophy (LVH). However, its reliability is often questionable when compared to the gold standard - echocardiography.The validation of ECG as a tool to diagnose LVH would benefit centres that lack access to echocardiography. AIM (1) To assess the efficacy of ECG criteria to screen for left ventricular ...

A recently described technique [Estes and Mayer, Biochim. Biophys. Acta 1712 (2005) 152-160] for the preparation of giant unilamellar vesicles (GUVs) in solutions with high ionic strength is examined. By observing a series of osmotic swellings followed by vesicle bursts upon a micropipette transfer of a single POPC GUV from a sucrose solution into an iso-osmolar glycerol solution, a value for t...

Simple ecosystems in the northern Pacific Ocean are particularly suitable to test the hypothesis. In 1970’s, communities at islands lacking sea otters were characterized by high density of sea urchins and a distinct lack of macrophytic vegetation.. In contrast, communities at islands with sea otters had relatively high kelp densities and low sea urchin biomass (Estes and Palsamino 1974). Howeve...
