THE PENETRATING RADIATION [PDF]

open access: yesScience, 1907
The announcement of the discovery of the penetrating radiation was made simultaneously by Rutherford and Cooke and McClennan and Burton in 1902. Investigations on radioactive substances had shown that some of these emit a very penetrating radiation, the γ radiation, resembling hard X‐rays.

“Mosaic Pattern” Foreign Bodies in Computed Tomography of the Head: A Specific Sign to Detect Tempered Glass-Related Head Injury

open access: yesIndian Journal of Neurosurgery, 2019
A 40-year-old male patient presented to us with a history of road traffic accident, followed by loss of consciousness and vomiting. Noncontrast computed tomography (NCCT) scan revealed frontal bone defect along with multiple “mosaic pattern” homogenously

Adhesive penetration of hardwood: a generic penetration model [PDF]

open access: yesWood Science and Technology, 2011
An analytical model to predict the penetration of adhesives into hardwood is proposed. Penetration into hardwood is dominated by the vessel network which prohibits porous medium approximations. The model considers two scales: (1) a one dimensional capillary fluid transport of a hardening adhesive through a single, straight vessel with diffusion of ...

Penetration Resistance and Penetrability in Pyramidal (Nano)Indentations [PDF]

open access: yesScanning, 2012
SummaryPyramidal nanoindentation loading curves were linearly plotted, normal force versus (penetration depth)3/2. The slope is penetration resistance k, its inverse penetrability. Linear correlations verify. All contributions to the indentation are included in the penetrability.

High resolution seismic and ground penetrating radar-geophysical profiling of a thermokarst lake in the western Lena Delta, Northern Siberia [PDF]

open access: yes, 2002
High resolution seismic and ground-penetrating radar (GPR) have been acquired over Lake Nikolay in the western Lena Delta (Siberia) in order to study the uppermost basin fill and the bordering frozen margins. GPR measurements were completed on the frozen
