Silurian echinoderms from Ireland are poorly known; hitherto, only three nominal species have been described, all crinoids and all from the Telychian (Upper Llandovery, Lower Silurian) Kilbride Formation in County Galway. A new species from this formation, Crepidosoma doylei, is the first recorded Irish Silurian ophiuroid (brittle star). The new species is described from five articulated specimens

This chapter deals with the Swedish tv-series Somewhere in Sweden, broadcast on public television (SVT) in 1973 and 1974 and seen by more than 60 percent of the Swedish population. It has since its initial screening, been broadcast on several occasions, always reaching large audiences. Here, an analysis is presented in which it is emphasised that the series expressed a common view of the World War

That Florida is in the midst of an ecological crisis is a perspective increasingly shared by academy, government, private industry and civil society. Ideas about the causes of the state’s environmental problems and how best to address them, however, are not so well aligned. While some are prone to emphasize the primacy of economic growth over environmental conservation, others argue that, like lov

Planar deformation features (PDFs) in quartz are the most widely used indicator of shock metamorphism in terrestrial rocks. They can also be used for estimating average shock pressures that quartz-bearing rocks have been subjected to. Here we report on a number of observations and problems that we have encountered when performing universal stage measurements and crystallographically indexing of PD

Physiological processes of terrestrial plants regulate the land-atmosphere exchange of carbon, water, and energy, yet few studies have explored the acclimation responses of mature boreal conifer trees to climate change. Here we explored the acclimation responses of photosynthesis, respiration, and stomatal conductance to elevated temperature and/or CO2 concentration ([CO2]) in a 3-year field exper

Planar chiral 5,11-disubstiuted dibenzo[a,e]cyclo-octatetraenes (dbCOTs) have been developed as the first useful chiral homologs to dbCOT-ligands for asymmetric applications. Methods enabling the preparation of such compounds on a gram-scale in enantiomerically pure form are described. Evaluated as ligands in rhodium(I)-catalyzed 1,4- and 1,2-arylation reactions, tertiary and quarternary stereogen

Both the ground (S0) and the lowest singlet excited states (S1) for a series of 5,10,15,20-tetraarylporphyrins consisting of two symmetrically and four asymmetrically substituted derivatives (A4, AB3, trans-A2B2, cis-A2B2, A3B and B4, where A=phenyl and B=mesityl) are studied by absorption and fluorescence spectroscopies. The rotational degree of freedom of the aryl rings is found to play a crucia

It is not known how long it takes from the initial neoplastic transformation of a cell to the detection of a tumor, which would be valuable for understanding tumor growth dynamics. Meningiomas show a broad histological, genetic and clinical spectrum, are usually benign and considered slowly growing. There is an intense debate regarding their age and growth pattern and when meningiomas should be re

Many European countries are becoming multicultural at a previously unseen rate. The number of immigrants including refugees has considerably increased since 2008, and especially after the beginning of the war in Syria. In 2015, 88,300 unaccompanied minors sought asylum in the Member States of the European Union (EU) and most came from Syria, Afghanistan, Iran, Iraq, Somalia and Eritrea. As a react

Xyloside analogues with substitution of the endocyclic oxygen atom by sulfur or carbon were investigated as substrates for β-1,4-galactosyltransferase 7 (β4GalT7), a key enzyme in the biosynthesis of glycosaminoglycan chains. The analogues with an endocyclic sulfur atom proved to be excellent substrates for β4GalT7, and were galactosylated approximately fifteen times more efficiently than the corr
