Hubble Turns 25

Modern non-invasive mechanical ventilation turns 25.

The history of non-invasive mechanical ventilation goes back more than 100 years, but it was not until 1987 when what we could call "modern" non-invasive mechanical ventilation was developed. The description of Delaubier and Rideau of a patient with Duchenne's disease who had been effectively ventilated through a nasal mask marked the start of a new era in the history of non-invasive mechanical...

Hubble-bubble in Iranian Folklore

Hubble-bubble has been the most common device for smoking tobacco in Iran and its neighboring. It has a folkloric name in every region. Hubble-bubble consists of a glass pitcher or pottery at the bottom, a wooden body in the middle, a wooden or plastic tube attached to the body for puffing, and a censer at the top to put tobacco and charcoal. Puffing causes the charcoal to catch fire and the to...

Galaxy morphology to I = 25 mag in the Hubble Deep Field

The morphological properties of galaxies between 21 mag < I < 25 mag in the Hubble Deep Field are investigated using a quantitative classification system based on measurements of the central concentration and asymmetry of galaxian light. The class distribution of objects in the Hubble Deep Field is strongly skewed towards highly asymmetric objects, relative to distributions from both the HST Me...

Mate choice turns cognitive.

Evolutionary psychology has revolutionized research on human mate choice and sexual attraction in recent years, combining a rigorous Darwinian framework based on sexual selection theory with a loosely cognitivist orientation to task analysis and mechanism modelling. This hard Darwinian, soft computational approach has been most successful at revealing the adaptive logic behind physical beauty, ...
