The influence of emissions an active volcano on the composition nanoparticles and ultrafine road dust was identified in urban area Andes. Although many cities are close to volcanoes, few studies have evaluated their composition. Air quality areas is significantly affected by non-exhaust (e.g. dust, brake wear, tire wear), however, natural sources such as volcanoes also impact chemical particles...

A4 62-year-old man was admitted with a four-week history of fever following an aorto-coronary bypass graft. The postoperative chest roentgenogram was normal. His past history included hypertension of 13 years' duration and coronary artery disease commencing three years previously. On examination, his tern-perature ranged between 37.5#{176} and 38.8#{176}C, a grade 2/6 apical systolic murmur was...

Abstract Schnöckel's [(AlCp*) 4 ] and Jutzi's [SiCp*][B(C 6 F 5 ) (Cp*=C Me are landmarks in modern main‐group chemistry with diverse applications synthesis catalysis. Despite the isoelectronic relationship between AlCp* [SiCp*] + fragments, their mutual reactivity is hitherto unknown. Here, we report on reaction giving complex salts [Cp*Si(AlCp*) 3 ][WCA] ([WCA] − =[Al(OR [F{Al(OR } 2 ; R =C(C...

The subject of this article is Latin reception Averroes’s treatise De substantia orbis, with special regard to the commentary practice in late Middle Ages. Numerous philosophical problems were taken up these commentaries following lead. most controver-sial among them concerning divine attributes, i.e., infinite power, efficient and final causality, and, consequently, God's ability create out no...
