Physicochemical properties, sugar profile, and non-starch polysaccharides characterization of old wheat malt landraces

2021

Abstract Craft beers produced by small breweries are becoming increasingly popular worldwide due to their unique composition, taste, and flavour. Wheat malt is a traditional brewing raw material with great potential to improve beer properties such as mouthfeel, foam, haze, and flavour. In this study, the malting quality of eight wheat varieties (four common and four durum) was evaluated to explore the feasibility of producing 100 % wheat malt beer from old landraces. The physicochemical characteristics such as friability, Kolbach index, viscosity, and colour, of the wheat malts indicated a better degree of modification in the common wheat varieties when compared to that of the durum wheat v…

Acceptability of the e-authentication in higher education studies: views of students with special educational needs and disabilities

2021

AbstractTrust-based e-assessment systems are increasingly important in the digital age for both academic institutions and students, including students with special educational needs and disabilities (SEND). Recent literature indicates a growing number of studies about e-authentication and authorship verification for quality assurance with more flexible modes of assessment. Yet understanding the acceptability of e-authentication systems among SEND students is underexplored. This study examines SEND students’ views about the use of e-authentication systems, including perceived advantages and disadvantages of new technology-enhanced assessment. This study aims to shed light on this area by exa…

Intensified forestry as a climate mitigation measure alters surface water quality in low intensity managed forests

2020

Climate change has led to a focus on forest management techniques to increase carbon (C) sequestration as a mitigation measure. Fertilisation and increased removal of biomass have been proposed. But these and other forest practices may have undesirable effects on surface water quality. In naturally acid-sensitive areas such as much of Fennoscandia a concern is acidification due to acid deposition in combination with forest practices that increase the removal of base cations and leaching of nitrate (NO3). Here we apply the biogeochemical model MAGIC to the coniferous-forested catchment at Birkenes, southernmost Norway, to simulate the effects of forest fertilisation and harvest on soil and s…

Modeling of biomass smoke injection into the lower stratosphere by a large forest fire (Part II): Sensitivity studies

2006

Abstract. The Chisholm forest fire that burned in Alberta, Canada, in May 2001 resulted in injection of substantial amounts of smoke into the lower stratosphere. We used the cloud-resolving plume model ATHAM (Active Tracer High resolution Atmospheric Model) to investigate the importance of different contributing factors to the severe intensification of the convection induced by the Chisholm fire and the subsequent injection of biomass smoke into the lower stratosphere. The simulations show strong sensitivity of the pyro-convection to background meteorology. This explains the observed coincidence of the convective blow-up of the fire plume and the passage of a synoptic cold front. Furthermor…

Empowerment as an affective-discursive technology in contemporary capitalism: insights from a play

2019

Over recent years, an increasing body of research in social and cultural studies has investigated the contemporary processes of social change from the point of view of affective capitalism. In this article, we take under scrutiny one of its technologies, namely, empowerment, by which we mean a state characterised by feelings of strength, ability and power that enable agency. More specifically, we investigate the way empowerment is presented in a cultural product, a play that tells a story about personnel training in a factory, shown in a city theatre in Finland. By linking recent theorisation of affective capitalism with an investigation of the intertextual and interdiscursive relations of …

Thermal response test analysis for U-pipe vertical borehole heat exchangers under groundwater flow conditions

2021

[EN] Conventional models used in the analysis of thermal response test data only consider conduction as heat transfer mechanism. In cases where presence of groundwater is detected, convection heat transmission plays an important role, so its influence must be determined in the calculation of the effective thermal conductivity, usually overestimated in these situations, increasing its value the higher the power injected and the time elapsed. In this work, based on the data collected in a borehole located at UPV (Valencia) in which have been carried out three thermal response tests with different characteristics, has been implemented a variation of the finite line source model introducing an …

Documenting the indignation: Responses to the 2008 financial crisis in contemporary Spanish cinema

2017

ABSTRACTThe aim of this article is to analyze two Spanish documentary films that reflect on the 2008 financial crisis in Spain, Mercado de futuros (Mercedes Alvarez, 2011) and No estamos solos (Pere Joan Ventura, 2015). These movies could be marked as political for their choice of a collective protagonist and for dealing with the issues of inequality with the purpose of appealing to mobilization and resistance to the neoliberal Western agenda that have provoked social cutbacks after the 2008 crisis. Mercedes Alvarez and Pere Joan Ventura follow the tradition of political documentaries traced by filmmakers such as Dziga Vertov, Joris Ivens, Pere Portabella, and Basilio Martin Patino and open…

Behaviour of the herbicide EL-107 in wheat and rape grown under controlled conditions

1987

Summary The behaviour of 14C-EL-107 has been evaluated in winter wheat and rape, which are tolerant and susceptible, respectively, under field conditions. After 10- to 13-days’growth under controlled conditions, seedlings were allowed to absorb the herbicide through the roots. Two experiments were conducted to study the absorption and the metabolism of EL-107. Absorption was estimated during a 5-day treatment at the rate of 1–47 μM, and metabolism was studied after a 1-day treatment at 14.7 μM. The results showed that (i) rape plants absorbed more herbicide than wheat, and translocated less radioactivity into their shoots, and (ii) the metabolism of EL-107 proceeded actively only in the sho…
