Six vegetative incompatibility (vic) loci have been identified in Cryphonectria parasitica based on barrage formation during mycelial interactions. We used hygromycin B- and benomyl-resistance as forcing markers in C. parasitica strains to test whether heteroallelism at each vic locus prevents heterokaryon formation following mycelial interactions. Paired strains that had allelic differences at...

PAHs are fused ring aromatic pollutants some of which are highly carcinogenic to humans and are persistent in the environment. The objective of this study was to develop a suitable extraction method for PAHs from river water samples, identify and quantify the individual compounds. An optimized reverse solid phase extraction (SPE) method was used after conditioning the sorbent to extract and pre...

In this study, enhancements to the numerical representation of sluice gates and turbines were made to the hydro-environmental model Environmental Fluid Dynamics Code (EFDC), and applied to the Severn Tidal Power Group Cardiff–Weston Barrage. The extended domain of the EFDC Continental Shelf Model (CSM) allows far-field hydrodynamic impact assessment of the Severn Barrage, preand post-enhancemen...

Functional life of any barrage project depends on functional stability of the concrete piers. The piers are constructed using concrete of different grades. Its durability is dependent on various factors viz. speed of running water, its aggressivity, temperatures fluctuations etc. The endurance capacity of these piers against these adverse conditions goes on reducing with passage of time. Gradua...

Genetic nonself recognition systems such as vegetative incompatibility operate in many filamentous fungi to regulate hyphal fusion between genetically dissimilar individuals and to restrict the spread of virulence-attenuating mycoviruses that have potential for biological control of pathogenic fungi. We report here the use of a comparative genomics approach to identify seven candidate polymorph...

Several tidal power schemes have been proposed for the River Severn Estuary between the South West of England and Wales. An indicative technology assessment has been undertaken in order to evaluate the so-called ‘Shoots Barrage’ over its foreseen lifespan of 120 years in terms of its cradle-to-site, operation and maintenance requirements. It would be located just upriver of the Severn road cros...
