Abstract Increased aquaculture production will result in increased amounts of waste produced, and these wastes are highly underexploited. Polychaetes might effectively consume such waste and transfer them into compounds as marine proteins and lipids. In our study, growth and nutritional composition of the polychaete worm Hediste diversicolor (O.F. Muller, 1776) were analyzed to evaluate i) the capability of H. diversicolor to utilize waste from land-based salmon smolt farms for growth and ii) th...

We have evaluated the cultivation potential of sugar kelp (Saccharina latissima) as a function of latitude and position (near- and offshore) along the Norwegian coast using a coupled 3D hydrodynamic-biogeochemical-kelp model system (SINMOD) run for four growth seasons (2012-2016). The results are spatially explicit and may be used to compare the suitability of different regions for kelp cultivation, both inshore and offshore. The simulation results were compared with growth data from kelp cultiv...

Juvenile scallops of Pecten maxiumus were studied to see the capability to clear out and incorporate salmon feed and feces (30 µg L-1). Algae were also given, in a low and high concentration in addition to feed and faeces, to mimic a winter and summer situation in Norwegian waters. Rhodomonas baltica and Chaetoseris muelleri were provided in a concentration of 50 µg L-1 and 300 µg L-1. The feeding trial lasted for 27 days. Clearance rate was measured to study filtration characteristics, while fa...

Integrated multi-trophic aquaculture (IMTA) has the potential of reducing open-cage fish farming impacts on the environment while also introducing new value chains. The aim of this study was to investigate the growth and composition of the kelp Saccharina latissima in salmon-driven IMTA, and to assess the spatial extent of the influence of salmon derived nitrogen in order to evaluate the upscaling potential for IMTA. S. latissima was cultivated 100, 200 and 1,000 m east and 1,000 m west of a 5,0...

The requesting of radiological investigations is frequently devolved to the ward-based doctors in training. In a National Health Service system that is regularly over capacity, radiological investigations are an expensive commodity often overused or poorly targeted by doctors. By considering the following ‘Commandments of Radiology’; doctors could target imaging more appropriately, resulting in higher quality information and hence, better patent care and value for money. ### Thou shalt give an a...

The aim of this study was to define the waste plume dynamics around a salmon farm in Norway. Systematic water sampling and numerical modeling were implemented to define nutrient concentrations in the upper water column at long-term (seasonal) and short-term (between and within days) time scales. Nutrient enhancement was observed for ammonium only, while the concentrations of orthophosphate and organic wastes were never higher than the background values. The spatial magnitude of cage effluent dis...

The House of God is a seminal work of medical satire based on the gruelling internship experiences of Samuel Shem at the Beth Israel Hospital. Thirteen ‘Laws’ were offered to rationalise the seemingly chaotic patient management and flow. There have been large shifts in the healthcare landscape and practice since, so we consider whether these medical truisms are still applicable to contemporary National Health Service practice and propose updates where necessary: People are sometimes allowed to d...

Abstract To investigate the effect of seasonal variation on macroalgae biomass characteristics and its related energy content, four different algae species, two from the Fucales order ( Fucus vesiculosus and Ascophyllum nodosum ), and two from the Laminariales order ( Saccharina latissima and Alaria esculenta ), were harvested during spring, summer, autumn and winter over one year. The biomethane potential and the elemental composition were determined for all samples. Both Fucales species showed...

Background Simulation based learning is often used to address concerns around practical procedures and more recently to improve awareness of human factor issues. Following the Francis and Berwick reports there has also been a focus of the inclusion of values based elements. Indeed, it has been suggested that the most likely reason why things go wrong is a failure of values-based practice (Fulford et al., 2012). A literature review was undertaken of simulation based sessions for Foundation Year D...
