River-bed erosion due to changing boundary conditions: performance of a protective measure
2018
Abstract. Due to the introduction of man-made sediment barriers along a river, the amount of sediment load entering the downstream river reach is different to that leaving the reach, and erosion processes occur downstream of the barrier itself. Designers are often required to take into account the scouring process and to include adequate protective measures against the local scour. This paper addresses the performance of bio-engineering protective measures against the erosion process. In particular, a green carpet, realized with real flexible vegetation, has been used as the protective measure against erosion processes downstream of a rigid bed. Analyses are based on experimental work carri…
Kjønn og religiøse grenser: Unge muslimer og kristnes forhandlinger av kjønn i migrantmenigheter
2019
Artikkelen belyser unge muslimer og kristnes forhandling av kjønn i migrantmenigheter: 1) Hvordan forhandler unge muslimer og kristne forventningene knyttet til kjønn, forbundet med religiøse klesdrakter og kjønnsdelte arbeidsoppgaver? Og 2), hva kan ungdommenes oppfatninger av religiøse koder og kjønnsdelte arbeidsoppgaver fortelle om symbolsk grensedragning mellom deres tilhørighet til en minoritetsgruppe og tilhørighet til majoritetssamfunnet? Data består av 23 kvalitative intervjuer med tenåringer og unge voksne i alderen 16–35 år. Ungdommene forhandlet stadig kleskoder og kjønnsdelte arbeidsoppgaver ut fra ulike religiøse, moralske og kulturelle forventninger. De skilte mellom religion…
Multiplicity results for asymmetric boundary value problems with indefinite weights
2004
We prove existence and multiplicity of solutions, with prescribed nodal properties, to a boundary value problem of the formu″+f(t,u)=0,u(0)=u(T)=0. The nonlinearity is supposed to satisfy asymmetric, asymptotically linear assumptions involving indefinite weights. We first study some auxiliary half-linear, two-weighted problems for which an eigenvalue theory holds. Multiplicity is ensured by assumptions expressed in terms of weighted eigenvalues. The proof is developed in the framework of topological methods and is based on some relations between rotation numbers and weighted eigenvalues.
Approaching electrical tomography
2009
A general approach to electrical tomography is here described, based on the distribution of the experimental data to the set of voxels in which the subsoil has been divided. This approach utilizes the sensitivity coefficients as factors of the convolution procedure to execute the back projection of the data, to obtain the 3D pictures of the subsoil. A subsequent probabilistic filtering technique is described to improve the pictures in view of sharp boundary models. Some models are finally presented, mostly regarding cubic buried anomalies as well as pipe-shaped and L-shaped anomalies.
Dannelse og samskaping av utdanning mellom akademia og sykehjem
2020
Cultivation and co-creation of education between academy and nursing home - a critical ethnography study Collaboration between academy and practice in education is emphasized. In this study, we explored and described boundary-crossing spaces, when co-creating an adjusted educational program for nursing students in a nursing home in Norway. Our aim was to explore how to learn person-centered dementia care through the participants in a learning community. A critical ethnographic approach and method with observations, field n otes, minutes of board, spontaneous meetings, and focus groups particularly with the students were used. Data were analyzed with six-step thematic analysis by Braun and…
Modification of the Structure and Nano-Mechanical Properties of LiF Crystals Under Irradiation with Swift Heavy Ions
2011
The modifications of the structure and hardness of LiF crystals under high-fluence irradiation with MeV- and GeV-energy Au ions have been studied using nanoindentation and atomic force microscopy. The formation of ion-induced dislocations and bulk nanostructures consisting of grains with nanoscale dimensions (50 nm - 100 nm) has been observed. The structural modifications are accompanied by a strong ion-induced hardening which is related to dislocation impeding by assemblies of defect aggregates, dislocation loops of vacancy and interstitial types and grain boundaries. For MeV ions, the modifications are localized in a thin surface layer (few mm) where much higher density of deposited energ…
Towards a sustainable leader-follower relationship: constructive dissensus, organizational virtuousness and happiness at work (haw)
2020
This paper examines how leaders and followers can interact positively under complex and bounded conditions. For this purpose, this paper conceptualizes and measures the concept of constructive dissensus. Constructive dissensus relates to a mutual understanding leading to a situation of coregulation. In addition, the relationship between constructive dissensus and happiness at work is examined on the basis of affective events theory. Furthermore, the mediating role of organizational virtuousness is assessed. Through structural equation modeling, a multilevel analysis was performed. Data from 130 bank branches and 606 employees were gathered. The results reveal a direct effect of constructive…
Searches for lepton number violation and resonances in K± → πμμ decays
2017
The NA48/2 experiment at CERN collected a large sample of charged kaon decays to final states with multiple charged particles in 2003–2004. A new upper limit on the rate of the lepton number violating decay K±→π∓μ±μ± is reported: B(K±→π∓μ±μ±)<8.6×10−11 at 90% CL. Searches for two-body resonances X in K±→πμμ decays (such as heavy neutral leptons N4 and inflatons χ ) are also presented. In the absence of signals, upper limits are set on the products of branching fractions B(K±→μ±N4)B(N4→πμ) and B(K±→π±X)B(X→μ+μ−) for ranges of assumed resonance masses and lifetimes. The limits are in the (10−11,10−9) range for resonance lifetimes below 100 ps.
On the typology of motion events in Aymara
2021
This paper investigates the lexicalization pattern of motion events in Aymara, an Andean language spoken in Bolivia, Peru, and Chile. After providing a description of the morphosyntax of translational motion events, this study aims at a preliminary typological classification of Aymara within the framework of Talmy’s typology (Talmy 2000). With this purpose, three diagnostic tests have been used to determine the basic framing-typology of motion events. These tests consider i) the size of manner-of-motion lexicon and, more broadly, the degree of manner salience, ii) the complex-path constructions and the use of ‘plus-ground’ clauses, iii) the expression of boundary-crossing. The results of th…
Rzeczywistość językowa a lingwistyka
2017
Language reality and linguistics. The author considers the ąuestion of the boundaries of language and linguistics, referring to the so-called full scientific theory. In the complex hierarchical-network structure of this theory, one can distinguish three levels: the philosophical basis, the theoretical-methodological level, and the empirical part. The article focuses on the ontological and epistemologica/-axiological assumptions of the theory of language. One may distinguish between four ways of the existence of language reality, which remain in mutual relatedness (concrete texts, language system, individual and col!ective language awareness). Discussing the contemporary cognitive situation …
