Mouse Anti-Human Salbutamol Hybridoma [SAL-78]

Dinoflagellate cysts are known to be potential seed banks which have an essential role in providing bloom history and also serve as useful indicators of eutrophication in marine environments. The present study is focused on the surface distribution of dinoflagellate cysts along the salinity gradient in two tropical estuaries, namely Chapora and Sal in Goa along the West coast of India. Surface sediments and water samples were collected monthly from February 2016-March 2017 which included all three seasons (pre-monsoon, monsoon, post-monsoon). A total of sixteen species of dinoflagellate cysts belonging to the order, Gymnodiniales, Gonyaulacales, and Peridiniales were recorded in the surface sediments. Cysts of heterotrophic dinoflagellates dominated the assemblage in both estuaries. Based on Redundancy Analysis (RDA), it was observed that the distribution of the dinoflagellate cysts were influenced by various physico-chemical parameters in both estuaries with salinity and grain size being the main explanatory variable. Nitrate limitation is noted to be a triggering factor for dinoflagellate cyst formation. Also, yessotoxin producer species, such as Gonyaulax spinifera, encountered in both estuaries showed an inverse relationship with nitrate concentration. This suggests that, high nitrate input in these estuaries might lead to excystment of Gonyaulax spinifera eventually leading to harmful blooms under eutrophic conditions.

Established in 1822 to process the coal tar and ammoniacal liquor residues of the Edinburgh gasworks, the Bonnington Chemical Works was an early and unusual facility in an era when coal gas residues were generally regarded as a burden. Its special place in the history of fossil fuel chemical manufacture has gone unnoticed and its operations have not been analysed previously, despite there being considerable source material. Here the lifecycle of the plant is explored in detail to understand its instigation, subsequent growth, and why it later closed, with emphasis on the ongoing evolution of its product range and corresponding manufacturing methods, production scale and prices. A key element in its extended success - the integrated scientific, technical and commercial skill of the various managers - is illustrated, as are interrelationships of the Bonnington works with the gradual development of the overall coal tar sector and broader industrial, political and social influences.
