High strength steel in fire [PDF]

open access: yes, 2015
High-performance materials are necessary to meet the future demands of the construction industry, which is strongly influenced by a growing population and depletion of natural resources. Sustainable development is central to research and development into

White Christian Nationalism: Adult Education and Threats to Democracy

open access: yesNew Directions for Adult and Continuing Education, EarlyView.
ABSTRACT Adult education has a historical and ongoing commitment to fostering democratic relationships, demonstrated by the tendency of adult education to be called upon when social change and realignment are most desirable. This article considers the philosophical and pragmatic possibilities for adult education at this moment, when White Christian ...

The isovector dipole strength in nuclei with extreme neutron excess [PDF]

open access: yesarXiv, 2008
The E1 strength is systematically analyzed in very neutron-rich Sn nuclei, beyond $^{132}$Sn until $^{166}$Sn, within the Relativistic Quasiparticle Random Phase Approximation. The great neutron excess favors the appearance of a deformed ground state for $^{142-162}$Sn.

Strength in numbers? Not always!

open access: yes, 2010
We propose a simple model to compute the probability of success under a quorum sensing strategy. We show that a quorum sensing strategy has a higher probability of success than an individualistic strategy when, for instance, the probability of success ...

Stereotactic radiosurgery for multiple small brain metastases using gamma knife versus single‐isocenter VMAT: Normal brain dose based on lesion number and size

open access: yesJournal of Applied Clinical Medical Physics, EarlyView.
Abstract Purpose The study evaluates rapid linear accelerator (Linac) single isocenter stereotactic radiosurgery (SRS) with Hyperarc for large target numbers. We compared to Gamma Knife (GK), which suffers from long treatment times and investigated causes of differences. Methods Linac SRS and GK treatment plans for patients receiving 18 Gy to the gross

Experimental investigation of the strength of anisotropic solids under biaxial loading oblique to the principal material directions

open access: yesCommunications, 2000
Realistic finite element ultimate load analyses of structural details as well as of shell structures made of anisotropic materials require suitable constitutive equations for the prediction of the deformational behavior and ultimate strength of biaxially
