A new microscope for the study of life science specimen has been developed. Special attention has been given to the problems of unstained samples, cryo-specimens and x-ray analysis at low concentrations.A new objective lens with a Cs of 6.2 mm and a focal length of 5.9 mm for high-contrast imaging has been developed. The contrast of a TWIN lens (f = 2.8 mm, Cs = 2 mm) and the BioTWTN are compared at the level of mean and SD of slow scan CCD images. Figure 1a shows 500 +/- 150 and Fig. 1b only 500 +/- 40 counts/pixel. The contrast-forming mechanism for amplitude contrast is dependent on the wavelength, the objective aperture and the focal length. For similar image conditions (same voltage, same objective aperture) the BioTWIN shows more than double the contrast of the TWIN lens. For phasecontrast specimens (like thin frozen-hydrated films) the contrast at Scherzer focus is approximately proportional to the √ Cs.

Looks at how Western law was interpreted and applied to perceived cannibals and corsairs in the Spanish Caribbean in the 16th and 17th c., by Spanish jurists in the period, and at the development of the cannibal and corsair image in Spanish culture. Author outlines the convergence of terms suggesting a growing semantic linkage between certain indigenous peoples, specially the famed "Carib cannibals", and foreign, mostly Western European, corsairs poaching on Spanish wealth. He describes how of the Caribs, said to be cannibals, involved in piracy, an image was constructed of not only cannibals, but also greedy criminals, or rebelers against Catholicism, in order to (legally) justify punishments or wars against them, and thus Spanish rule. He then discusses how of French, British, and other corsairs in the Caribbean involved in piracy against the Spanish, an in some ways similar image was painted of fanatical canine types ruled by appetites, and also of anti-Catholic heretics and criminals, in order to justify punishments as well as the Spanish claim on rule of the Caribbean.
