<p> The decay of 3.5 minute 89Kr to levels in 89Rb has been investigated with small and large volume Ge(Li) detectors used singly and in coincidence. A total of 160 gamma rays have been attributed to the nu...
Incremental Collapse of Reinforced Concrete Frames
<p> A research program is presented for assessing the plastic
collapse load and incremental collapse load of reinforced concrete
frames. This investigation attempts to establish a range of validity
of simple plastic...
On Short-term and Sustained-load Analysis of Concrete Frames
<p> A Matrix Stiffness-Modification Technique has been proposed
for the inelastic analysis of ·reinforced concrete frames subjected
to short term or sustained loads. To check the applicability of the
analytical method, ...
An Evaporation Model for High Latitude Upland Lichen Surfaces
<p> Energy-budget calculations and equilibrium model estimates of evaporation from a lichen-dominated upland site in the Hudson Bay low-lands are presented. The energy budget calculations reveal that the lichen surface is relatively...
MacSphere is·McMaster University’s Institutional Repository (IR). The purpose of an IR is to bring together all of a University's research under one umbrella, with an aim to preserve and provide access to that research. The research and scholarly output included in MacSphere has been selected and deposited by the individual university departments and centres on campus.
To contribute to McMaster's Institutional Repository, please sign on to MacSphere with your MAC ID. If you have any questions, please contact the Office of Scholarly Communication.
Students wishing to deposit their PhD or Masters thesis, please follow the instructions outlined by the School of Graduate Studies.
