The second effect is the variation of the van der Waals radius with angle relative to an internal covalent bond. A particularly well-studied example is that of Cl–Cl interactions in crystals of both the element itself and many organochlorine compounds. ...
[102]. The same approach is taken for identifying a transferrin homolog inHaliotis discusdiscus(Gastropoda) as the protein corresponding to a 2187-bp open reading frame[103]. Its binding of ferric ions makes transferrin a crucial element iniron transportand distribution but also abacteriostatic ...
Art in an Age of Mass Culture的剧情简介 ··· Conceived as a response to the much discussed and now legendary exhibition HIGH & LOW: HIGH ART AND POPULAR CULTURE, a survey of the spectacle of the interaction of consumer culture and the artistic avant-garde which opened at the Museum of...
Furthermore, the positions of ribs and spars have to be defined as load carrying structure. In this way, a geometric model is created. Taking suitable meshing parameters into account, a finite element (FE) model is derived. For most of the structure, shell elements are used. Several mass ...
I am an amateur, a dabbler, a passionate hobbyist when it comes to music. But music is an essential part of who I’ve become since the beginnings of my fascination with what might be termed “new classical” music back around the age of 10 or so (more on that in a later essay)....
Fears that automation will create massive unemployment go back to the nineteenth century, and so far they have never materialized. Since the beginning of the Industrial Revolution, for every job lost to a machine at least one new job was created, and the average standard of living has ...
fire devastated the original palace. It's a mix of Gothic and Elizabethan styles, a mass of pinnacles and tracery. The clock tower known around the world, Big Ben, is 320-feet high. Big Ben is of course the name applied to this tower but it is in fact the name of its main bell....
This paper aims at contributing to a better understanding of the beginnings of tin and bronze metallurgy in Central Asia by investigating a hitherto unique piece of a bronze slag. The object was originally discovered as a stray find only 4 km away from the large copper-tin deposit of Mušis...

The monoisotopic mass of an ion is calculated using the ‘exact’ mass of the predominant isotope of each element. The average mass (or chemical mass) is a weighted average of the natural isotopes for the atomic mass of each element. The nominal mass is the mass of the predominant isotope...
