Removal of Hexavalent Chromium from Aqueous Solutions Using Biopolymers
2018
AbstractTwo biopolymers were prepared by reaction of chestnut and quebracho tannins with gelatin extracted from untanned hide wastes. Obtained biopolymers were evaluated as adsorbents for removing ...
‘Less Stale, Only Slightly Less Male, but Overwhelmingly Less Pale’: the 2015 New Conservative Brexiters in the House of Commons
2019
AbstractThis article will study the new face of Conservative Euroscepticism in the House of Commons, with a special focus on the 2015 intake of MPs who were supposedly ‘less stale, male and pale’ and their attitudes to the British referendum on the EU. In this respect, this article will also take a specific interest in new Conservative Black and Asian Minority Ethnic (BAME) MPs who turned out to be more active on the ‘leave’ side of the referendum campaign, thus serving as a showcase for the party's strategy of ‘decontaminating’ the Brexit brand and its hyperglobalist geopolitical perspective.
Serious Game Design for Flooding Triggered by Extreme Weather
2017
Managing crises with limited resources through a serious game is deemed as one of the ways of training and can be regarded as an alternative to a table-top exercise. This article presents the so-called “Operasjon Tyrsdal” serious game, inspired by a real case of extreme weather that hit the west coast of Norway. This reference case is used to add realism to the game. The game is designed for a single player, while the mechanics are framed in such a way that the player will have limited resources, and elevated event pressure over time. Beside applying an iterative Scrum method with seven Sprint cycles, we combined the development work with desk research and used the involvement of testers, i…
A method for reclaiming nutrients from aquacultural waste for use in soilless growth systems
2020
Abstract The aim of this work was to develop a method that allows the recovery of nutrients from aquaculture sludge, not only to alleviate the disposal problem, but also to address the future scarcity of non-renewable fertilizers. This method includes two steps: Nutrient mobilization using aerobic digestion followed by solids precipitation using chitosan as the flocculant. The aerobic digestion experiments were conducted in aerated batch reactors, while a jar test apparatus was used to assess the capacity of chitosan to remove total suspended solids (TSS) and turbidity. During aerobic digestion, the concentration of soluble N (sum of NH4-N, NO2-N, NO3-N) increased from 181 mg/L at the start…
Ensuring the Reliability of an Autonomous Vehicle
2017
International audience; In automotive applications, several components, offering different services, can be composed in order to handle one specific task (autonomous driving for example). Nevertheless, component composition is not straightforward and is subject to the occurrence ofbugs resulting from components or services incompatibilities for instance. Hence, bugs detection in component-based systems at thedesign level is very important, particularly, when the developed system concerns automotive applications supporting critical services.In this paper, we propose a formal approach for modeling and verifying the reliability of an autonomous vehicle system, communicatingcontinuously with of…
Can Gender Equality Be Institutionalized?
1999
Institutional innovation can be understood as launching an institution within an intact institutional and cultural context. Such attempts of guided institutionalization pose a crucial built-in problem. The goal of institutional innovation is to create new routine-reproduced, taken-for-granted behaviour patterns. The means to reach this goal is rational, purposive action, which is the very opposite of routinized enacting. This immanent contradiction of institutional innovation is discussed on the basis of a comparative study on the introduction of gender quotas in Norwegian and German political parties. The analysis draws on more than 50 qualitative interviews with parliamentarians from bot…
How women are imagined through conceptual metaphors in United Nations Security Council Resolutions on women, peace and security
2017
United Nations Security Council Resolution 1325 is a landmark pronouncement on the Women, Peace and Security Agenda. Not only does this resolution highlight the important role of the involvement of women in peace processes, but it also stresses the importance of their equal participation in all efforts for the maintenance and promotion of peace. Furthermore, it also triggers the approval of some other resolutions, which are all further elaborations on that first document. The aim of this paper is to analyse, from a cognitive linguistic perspective, the way in which women are actually narrated in these pronouncements by means of the two conceptual metaphors that are most often repeated: WOME…
A Novel Intelligent Technique for Product Acceptance Process Optimization on the Basis of Misclassification Probability in the Case of Log-Location-S…
2019
In this paper, to determine the optimal parameters of the product acceptance process under parametric uncertainty of underlying models, a new intelligent technique for optimization of product acceptance process on the basis of misclassification probability is proposed. It allows one to take into account all possible situations that may occur when it is necessary to optimize the product acceptance process. The technique is based on the pivotal quantity averaging approach (PQAA) which allows one to eliminate the unknown parameters from the problem and to use available statistical information as completely as possible. It is conceptually simple and easy to use. One of the most important featur…
Exploring relationships between grid cell size and accuracy for debris-flow susceptibility models: a test in the Giampilieri catchment (Sicily, Italy)
2016
Debris flows are among the most hazardous phenomena in nature, requiring the preparation of suscep- tibility models in order to cope with this severe threat. The aim of this research was to verify whether a grid cell-based susceptibility model was capable of predicting the debris- flow initiation sites in the Giampilieri catchment (10 km2), which was hit by a storm on the 1st October 2009, resulting in more than one thousand landslides. This kind of event is to be considered as recurrent in the area as attested by historical data. Therefore, predictive models have been prepared by using forward stepwise binary logistic regression (BLR), a landslide inventory and a set of geo- environmental …
The role of social perception in disaster risk reduction: Beliefs, perception, and attitudes regarding flood disasters in communities along the Volta…
2017
Abstract People's perceptions of natural, spiritual, and social phenomena are socially constructed. Social perception is important because it helps people to make sense of the physical and social world and therein interact with it. Earlier research specializing in the study of human behaviour has emphasized a linkage between people's perceptions and their behaviour. In this article, the authors employ a similar theory with the intent of proposing a theoretical framework that examines the factors that influence people's perception and attitude (mitigation and response) towards the hazards they face. This discussion is done on the premise of “culture”, “experiences” and “disaster risk reducti…
