The Penetrating Radiation

Penetrating Shortwave Radiation

Few of the Pelecaniformes are globally threatened, although some island and inland populations of pelecaniform birds have become extinct in the face of habitat loss and contamination. In some species (e.g., double-crested cormorant, white pelican), numbers are increasing with near-exponential growth, while in others (e.g., Dalmatian pelican) population abundance is rapidly decreasing. Island sp...

Penetrating Radiation at the Surface of and in Water

Foreword – At the beginning of the twentieth century, two scientists, the Austrian Victor Hess and the Italian Domenico Pacini, developed two brilliant lines of research independently, leading to the determination of the origin of atmospheric radiation. Before their work, the origin of the radiation – today called “cosmic rays” – was strongly debated, as many scientists thought that these parti...

Visualization of penetrating transmural arteries in situ by monochromatic synchrotron radiation.

BACKGROUND Penetrating transmural arteries with a diameter of < 500 microns are considered to be a critical vascular component that causes a transmural variation of myocardial blood flow under various pathophysiological conditions. However, the conventional coronary angiographic system is not oriented to the visualization of such small arteries as these. METHODS AND RESULTS We magnified and m...
