In the photosynthetically most active spring, summer and autumn vege tation period the investigated grassland did maintain a relatively strong daytime carbon gain. During winter the grassland displayed a slight daytime carbon loss. These data sugge

Parallel coenological and synphysiological examinations were carried out on three typical xerophilous loess grassland stands of Salvio-Festucetum rupicolae community in the Gödöllö Hills, near Isaszeg village. Three stand types, a Carex humilis, a

Bryophytes, especially mosses, represent a largely untapped resource for monitoring and indicating effects of climate change on the living environment. They are tied very closely to the external environment and have been likened to'canaries in the co

The combined use of different mass spectrometric ionization methods and MS/MS techniques provide the possibility to differentiate between stereoisomers or epimers. In this paper the mass spectral decomposition of 11alpha- and 11beta-substituted estra

Teutsch G. and Belanger A. treated 5α,10α epoxides with Grignard-reagents catalyzed by copper(I) ions. The reaction with steroidal epoxides proceeded with complete regio- and stereospecificity, leading exclusively to the 11β-substituted compounds.

The first use of neuromuscular blocking agents (muscle relaxants) in clinical practice (1942) revolutionised the practice of anaesthesia and started the modern era of surgery. Since 1942 introduction of tubocurarine (18) neuromuscular blocking agents
