RECREATIONAL ANGLING TOURNAMENTS: PARTICIPANTS' EXPENDITURES. ESRI Research Bulletin 2017/05 [PDF]
, 2017 Tournaments are a common feature of recreational angling, with upwards of 300 competitive angling events per annum in Ireland. Prior research has indicated that angler expenditures in Ireland exceed €555 million per annum but little is known specifically

Advanced Engineering Materials, EarlyView.High‐frequency (HF) welding of steel is limited by oxide inclusions that degrade weld quality. This study demonstrates, for the first time, the integration of a nonthermal Ar/H2 dielectric barrier discharge (DBD) plasma jet into HF welding. Local plasma treatment provides effective shielding and in‐situ oxide reduction, resulting in markedly fewer and ...

Valuing trout angling benefits of water quality improvements while accounting for unobserved lake characteristics: An application to the Rotorua Lakes [PDF]
, 2011 Trout angling is one of the most popular water-based recreational activities in the Rotorua Lakes. Despite the high demand for trout angling and other recreational purposes, water quality in some of these lakes has been declining over the past decades ...

Advanced Engineering Materials, EarlyView.A numerical–experimental framework is developed for characterizing multi‐matrix fiber‐reinforced polymers (MM‐FRPs) combining epoxy and polyurethane matrices. Harmonic bending tests are integrated with finite element model updating (FEMU) to simultaneously identify elastic and viscoelastic material parameters.

An Economic Assessment of the Costs and Benefits of Natura 2000 Sites in Scotland [PDF]
, 2004 In accordance with the European Commission "Habitats Directive" (Directive 92/43/EEC) and the "Birds Directive" (Directive 79/409/EEC), Scotland must contribute to the development of a UK network of protected areas that represent the most important ...

Effect of Oxygen Content on Surface and Subsurface Integrity During Turning of Ti–6Al–4V
Advanced Engineering Materials, EarlyView.This study examines how oxygen content in the ambient atmosphere affects the surface and subsurface properties of Ti–6Al–4V during turning. Results show that oxygen does not influence surface roughness. However, machining in an extremely high vacuum‐adequate atmosphere increases surface hardness by up to 7.8% and induces compressive residual stresses ...

A fisheries management plan for the River Tweed in the Scottish Borders [PDF]
, 1998 The River Tweed is, in rod-catch terms, the second most important river in Britain for Atlantic salmon, with an annual rod catch of ca.10,000 fish. This article gives an outline of the second edition of the Tweed Fisheries Management Plan, which is ...

Oxide‐Free Titanium Coatings by Wire Arc Spraying in a Silane‐Doped Inert Atmosphere
Advanced Engineering Materials, EarlyView.A silane‐doped argon atmosphere enables the production of oxide‐free titanium coatings via twin‐wire arc spraying at ambient pressure. This innovative approach eliminates residual oxygen, creating process conditions that prevent oxidation and nitride formation.
