Compression and crevasses in vitreous sections under different cutting conditions.
Compression and crevasses are common cutting artefacts in cryo-ultramicrotomy of vitreous sections. They can be reduced or suppressed under optimal cutting conditions. In the present study, compression and thickness were measured for different cutting speeds and knife angles. It was found that compression decreased with feed and that crevasses appeared only above a certain thickness. The optima...

متن کاملGetting to the Bottom of “ Triple Bottom Line ”
In this paper, we examine critically the notion of “Triple Bottom Line” accounting. We begin by asking just what it is that supporters of the Triple Bottom line idea advocate, and attempt to distil specific, assessable claims from the vague, diverse, and sometimes contradictory uses of the Triple Bottom Line rhetoric. We then use these claims as a basis upon which to argue (a) that what is soun...
متن کاملAutomatic Glacier Surface Analysis from Airborne Laser Scanning
Glaciers are interesting phenomena to scientists, mountaineers and tourists. Glaciers have a great impact on the local economy, power generation and water supply. Furthermore, the behaviour of glaciers is influenced by climate variations, such as changes in temperature. Monitoring glaciers can therefore give valuable insight to glaciologists. Two aspects of glaciers that can be monitored are th...
متن کاملLattice QCD signal for a bottom-bottom tetraquark
Utilizing lattice QCD results for the potential of two static antiquarks and two dynamical quarks as well as quark model techniques for the dynamics of two heavy antiquarks in a cloud of two light quarks, we are provided with an accurate framework for the study of possibly existing heavy-heavylight-light tetraquarks. Among the possible quantum numbers of such a system, we find binding in only o...
