We show the existence of bilimits of 2-cofiltered diagrams of topoi, generalizing the construction of cofiltered bilimits developed in [2]. For any given such diagram represented by any 2-cofiltered diagram of small sites with finite limits, we construct a small site for the bilimit topos (there is no loss of generality since we also prove that any such diagram can be so represented). This is d...

A D Lii CASE 3 A Singaporean

The practice of implanting foreign bodies into the penis for psychosexual reasons has been reported in journals of urology, radiology, and dermatology.'-4 It has not, to our knowledge, been reported in journals of venereology. Venereologists should be familiar with this practice, which may otherwise be mistaken for other pathological conditions. We here report three cases seen at this hospital ...

Absorption correction of two-color LII-signals

In this work we present a numerical iterative procedure for the evaluation of the effect of signal absorption in two-color laser-induced incandescence (2C-LII) measurements. The correction process is applied to experimental results, previously published by our group, in an axisymmetric diffusion flame. We have studied the influence of signal trapping on peak soot temperature and on soot volume ...

Rotational motion in LiBH4/LiI solid solutions.

We investigated the localized rotational diffusion of the (BH(4))(-) anions in LiBH(4)/LiI solid solutions by means of quasielastic and inelastic neutron scattering. The (BH(4))(-) motions are thermally activated and characterized by activation energies in the order of 40 meV. Typical dwell times between jumps are in the picosecond range at temperatures of about 200 K. The motion is dominated b...
