<i>In situ</i> monitoring of PISA morphologies

Beyond Pisa 2015: a Longer-term Strategy of Pisa

d) PISA assesses both subject matter content knowledge, on the one hand, and the capacity of individuals to apply that knowledge creatively, including in unfamiliar contexts, on the other. Until now PISA has assessed students in three main domains in each round: reading, mathematics and science. These domains cover some of the fundamental skills needed to continue on with higher education or su...

Optical observations of the luminous Type IIn

The luminous Type IIn Supernova (SN) 2010jl shows strong evidence for the interaction of the SN ejecta with dense circumstellar material (CSM). We present observations of SN 2010jl for t ∼ 900 d after its earliest detection, including a sequence of optical spectra ranging from t = 55 to 909 d. We also supplement our late time spectra and the photometric measurements in the literature with an ad...

Morphologies of

We have examined in detail the morphologies of seven z ∼ 1.5 passively evolving luminous red galaxies using high resolution HST NICMOS and ACS imaging data. Almost all of these galaxies appear to be relaxed systems, with smooth morphologies at both rest-frame UV and visible wavelengths. Previous results from spectral synthesis modeling favor a single burst of star formation more than 1 Gyr befo...

The PISA method simplified.

We have read with interest the study by Messika-Zeitoun et al. 1 showing that using a fixed angle value of 100 provides an accurate estimation of the miral valve area (MVA) by the proximal isove-locity surface area (PISA) method in patients with mitral stenosis (MS). We appreciate the study as a means to make PISA method more popular in assessing the MVA. Although not cited in the article, we a...
