Danielsson (1965) has recently described the use of non-fluorescent membrane filters and immunofluorescence staining for the identification of certain bacteria in water. The principal advantages of the procedure were that it was rapid; that it could separate and identify a small number of organisms from a relatively large volume of fluid; and that it allowed a quantitative estimate of the conce...
Acid-toxicity tests were performed using two crayfish species, Procambarus clarki Girard and Orconectes rusticus Girard to determine the median lethal pH (LC60) after 4 days exposure to acid. Four-day LC50 values of pH 2*5-2-8 were observed, indicating that these animals are more acid-tolerant than most fish species. Haemolymph acid-base variables and major ion concentrations were measured duri...

Very common throughout mountains at lower elevation on alluvial gravels the northern Emirates. Rapidly colonizes new roadsides, e.g. around Hatta (Western, 1989).

Three new diterpene esters with a myrsinol-type skeleton have been isolated from Euphorbia decipiens BOISS. & BUHSE. The structure elucidation of the isolated compounds was based primarily on two-dimensional (2D)-NMR techniques including correlation spectroscopy (COSY), heteronuclear multiple quantum coherence (HMQC), heteronuclear multiple bond correlation (HMBC) and nuclear Overhauser effect ...
