A number of Extremely Large Telescopes for visual-infrared and adjacent wavelengths are in various degrees of progress. All have primary mirrors with equivalent diameters larger than 20 m and are intended for operation with adaptive optics systems. We discuss several ELT observing parameters as functions of wavelength. Stellar energy distributions and atomic line spectra are inspected as are the t
This study investigates the establishment of alternative cell fates during embryoid body differentiation when ES cells diverge into two epithelia simulating the pre-gastrulation endoderm and ectoderm. We report that endoderm differentiation and endoderm-specitic gene expression, such as expression of laminin 1 subunits, is controlled by GATA6 induced by FGF. Subsequently, differentiation of the no

In Vitaby parish are the ruins of a castle built around 1200 and deserted before 1300. An excavation was made in 1911 and again by the author in 2001 and 2002. The construction i unique in Europe with a support wall for the shellkeep 5,5 meters high, going all through the motte down to the peat. The castle was probably owned by the family Galen
The syntax of imperatives makes an interesting test case when investigating word order, verb raising and cliticisation across languages and their acquisition. This paper looks at language differentiation, i.e. language-specific parameter setting, in the imperative constructions of a bilingual child, "Katla", acquiring a verb-raising language, Icelandic, as well as English, not a verb-raising langu
It is widely recognised that knowledge and highly-skilled individuals as “carriers” of knowledge (i.e. knowledge spillover agents) play a key role in impelling the development and growth of cities and regions. In this chapter we discuss the relation between the mobility of talent and knowledge flows. In this context, several issues are examined, including the role of highly-skilled labour for regi
The incidence of evaporating `black widow' pulsars (BWPs) among all millisecond pulsars is far higher in globular clusters than in the field. This implies a special formation mechanism for them in clusters. Cluster millisecond pulsars in wide binaries with white dwarf companions exchange them for turnoff-mass stars. These new companions eventually overflow their Roche lobes because of encounters a
Cigarette smoke exposure is well known to cause cardiovascular and airway diseases, both of which are leading causes of death and disability in the world. However, the molecular mechanisms that link cigarette smoke to cardiovascular and airway diseases are not fully understood. Vascular and airway hyper-reactivity plays an important role in the pathogenesis of cardiovascular and airway diseases. R
