Role of the N-*(1535) in the J/psi -> pp and J/psi -> p(+)Lambda reactions

2009

We study the J/psi -> p eta p and J/psi -> pK(+)Lambda reactions with a unitary chiral approach. We find that the unitary chiral approach, which generates the N-*(1535) dynamically, can describe the data reasonably well, particularly the ratio of the integrated cross sections. This study provides further support for the unitary chiral description of the N-*(1535). We also discuss some subtle differences between the coupling constants determined from the unitary chiral approach and those determined from phenomenological studies

#selberdenken.

2023

Soziale Medien stellen wichtige Bühnen für zeitgenössische Konflikte um Wissen und Wahrheit dar. Der Artikel widmet sich vor diesem Hintergrund dem Gebrauch des Hashtags #selberdenken auf Twitter. Mittels einer quantitativen Datenanalyse wird zunächst die Konjunktur der Verwendung des Hashtags nachgezeichnet. Eine anschließende hermeneutische Sequenzanalyse zeigt, wie in seinem Gebrauch ein Anspruch auf epistemische Autonomie zum Ausdruck gebracht wird: Allein die eigenen Erfahrungen, Interpretationen und Quellen gelten als vertrauenswürdig. Dies korrespondiert mit einem grundlegenden Misstrauen in die von den Massenmedien konstruierten Realitäten und einer Trivialisierung von Erkenntnispro…

Presencia de hiena manchada en los depósitos basales (Pleistoceno Superior final) del yacimiento arqueológico de La Cueva de Nerja (Málaga, España)

2021

La Cueva de Nerja (Maro, témino municipal de Nerja, provincia de Málaga, S de España) contiene un importante yacimiento arqueológico en la zona de su antigua entrada (salas de la Torca, de la Mina y del Vestíbulo) cuya cronología se encuentra comprendida entre ca. 25.000 y ca. 3.000 años BP, secuencia que cubre el Pleistoceno superior final y gran parte del Holoceno. En el nivel basal de la Sala del Vestíbulo (NV13, cuadros C-4 y B-8), acotado en una horquilla cronológica comprendida entre ca. 25.000 y ca. 20.000 años BP, se han recuperado cuatro fragmentos de coprolito de color blanco atribuibles la hiena manchada de las cavernas (Crocuta crocuta spelaea).

The Village of the Year Competition Constructing an Ideal Model of a Rural Community in Finland

2016

The Village Action Association of Finland (SYTY) organizes the Village of the Year competition annually to award active rural communities. The competition has taken place since 1985, but after the village action movement was integrated into Finnish rural policy networks in the 1990s, it also became a part of rural policy instruments. The competition can be considered a governing technique that constructs norms and an ideal model for rural communities to pursue. In this article, I study the representation of an ideal rural community by analysing the criteria of the competition. I also look for changes to see whether the integration of the village action movement into rural policy is reflecte…

Residual a posteriori error estimation for frictional contact with Nitsche method

2023

We consider frictional contact problems in small strain elasticity discretized with finite elements and Nitsche method. Both bilateral and unilateral contact problems are taken into account, as well as both Tresca and Coulomb models for the friction. We derive residual a posteriori error estimates for each friction model, following [Chouly et al, IMA J. Numer. Anal. (38) 2018, pp. 921-954]. For the incomplete variant of Nitsche, we prove an upper bound for the dual norm of the residual, for Tresca and Coulomb friction, without any extra regularity and without a saturation assumption. Numerical experiments allow to assess the accuracy of the estimates and their interest for adaptive meshing …

Lärarstudenter som aktörer i interaktiv observation och handledning: En studie om digitala redskap i VFU-handledning på övningsskolor

2018

Source at https://doi.org/10.23865/hu.v8.1078. Licensed CC BY-NC-ND 4.0. Syftet med denna artikel är att bidra med kunskap om hur digitala redskap kan påverka lärarstudenters deltagande i handledningsprocessen. Trots att lärarstudenter och handledare ofta befinner sig i digitala klassrumsmiljöer används digitala redskap endast i begränsad omfattning under handledningsprocessen. Med utgångspunkt i Wengers teori om lärande i en praktikgemenskap har lärarstudenter och handledare arbetat med stöd av digitala observationsunderlag. Processen har studerats på fyra övningsskolor. Information om studenternas erfarenheter av handledningen har samlats in via enkäter och fokusgruppsamtal. Resultatet vi…

Ciclo del carbono y modelización biogeoquímica de un lago somero hipertrófico: la Albufera de Valencia

2015

Los lagos someros son uno de los ecosistemas acuáticos más numerosos a nivel global y hacen posible el desarrollo de multitud de actividades de interés económico y recreativo. En las últimas décadas, gran parte de estos lagos se han visto sujetos a un proceso de eutrofización cultural que a menudo conlleva una transición desde un estado "claro" caracterizado por una alta transparencia del agua y gran abundancia de macrófitos, a un estado "turbio" caracterizado por una baja transparencia del agua, dominancia de fitoplancton y macrófitos sumergidos prácticamente ausentes. El cambio que experimentó la Albufera de Valencia al estado turbio a principios de los años 1970 como resultado de un inte…
