An experiment, which investigated whether the format in which information is stored affects the outcomes of ready reference transactions in terms of efficiency and accuracy, found that bibliographic questions are more efficiently answered online, while factual questions are more efficiently answered with print sources. Neither mode was found to be more accurate.
Motivated by experimental observations, the shear-lag method has been employed to model the competition between the transverse cracking and delamination modes of failure that occur in cross-ply AS4/3501-6 carbon-fibre/epoxy coupons subjected to fatigue. The results explain Nike Air Max 1 Fb Yeezy
the extensive delaminations and reduced crack densities that arise under immersed fatigue conditions, as compared with fatigue in air.
Daylight Saving Time is controversial due to its alleged negative impact on individual well-being. Using panel data from Germany we find evidence that the transition to summer Nike Air Max 2013 Limited Edition
time has negative influence on general life satisfaction and mood, which is stronger for those in full time employment.
The notion of Ramanujan graph has been extended to not necessarily regular graphs by Y. Greenberg. We construct infinite trees with infinitely many finite quotients, none of which is Ramanujan. We give a sufficient condition for a finite graph to be covered by such a tree.
