The ISM 1500 Instructional System was the only commercial system produced by a single manufacturer that had an integrated student terminal configuration providing a keyboard and light pen response mode, CRT-based graphics, audio, and static film projection. Experimental instructional systems had been developed by ISM prior to a prototype version of the 1500 Instructional System, which was teste...

osteo-malacia, oven the acute form, developing during pregnancy, may be cured by the injection of adrenalin. This interest in Germany has become so general as to lead to this method of treatment being ordinarily spoken of as the " Bossikur." The interest in the subject has been extended very greatly, during the last few months, by further assertions, of Professor Bossi, based on experimental wo...

We present results of a density functional theory study of MnO in the wurtzite structure. Our motivation is provided by recent experiments reporting ferromagnetism in Mn-doped wurtzite-structure ZnO. We find that wurtzite MnO a) is not strongly energetically disfavored compared with the ground state rocksalt MnO, b) shows strong magneto-structural coupling and c) has a piezoelectric response th...
