Physiol. 2 I I (6) : 1305-1308. 1966.-A marked increase in myoglobin concentration was observed in thigh muscle (I. 3 -+ 3.2 mg/g) and masseter (4.7 -+ 10.1 mg/g) from northern red-backed voles (Clethrionomys rutilus dawsoni) during winter (Jan.-Feb.) as compared with ...

This paper examines determinants of Olympic success at the country level. Does the U.S. win its fair share of Olympic medals? Why does China win 6% of the medals even though it has 1/5 of the world’s population? We consider the role of population and economic resources in determining medal totals from 1960-1996. We also provide out of sample predictions for the 2000 Olympics in Sydney. ∗100 Tuc...

Understanding whether the gradient in children's health becomes steeper with age is an important first step in uncovering the mechanisms that connect economic and health status, and in recommending sensible interventions to protect children's health. To that end, this paper examines why two sets of authors, Chen et al. [Socioeconomic status and health: Do gradients differ within childhood and a...

The silkworm, Bombyx mori, is one of the major insect model organisms, and its draft and fine genome sequences became available in 2004 and 2008, respectively. Transposable elements (TEs) constitute ~40% of the silkworm genome. To better understand the roles of TEs in organization, structure and evolution of the silkworm genome, we used a combination of de novo, structure-based and homology-bas...

The type specimen of peisleyite has been reinvestigated by a combination of scanning electron microscopy, electron probe microanalysis (EPMA) and synchrotron powder X-ray diffraction. Morphological investigation showed that mats of peisleyite crystals, individually <3 mm across, are intergrown with wavellite veinlets to form the white cryptocrystalline material that is typical of ‘peisleyite’. ...
