Contamination of mafic magma by partial melting of dolomitic xenoliths
2001
Mg-skarns enclosed in dunite cumulates of the Neo-Proterozoic Ioko-Dovyren intrusion (northern Baikal region, Russia) can be traced to silica-poor dolomitic host rock layers. The dominant minerals of the skarns are brucite (pseudomorph after periclase), forsterite and Cr-poor spinel. Rapid heating of quartzpoor dolomitic xenoliths led to the formation of minor olivine, followed by the breakdown of dolomite to calcite and periclase. Xenoliths were partially melted upon further heating resulting in a calcite melt. This low-density melt was quantitatively squeezed out, mixed with the surrounding mafic magma and left behind periclase and olivine. This caused the crystallization of new olivine w…
Generation Z and Organizational Listening on Social Media
2020
Young people are avid users of social media and have appeared as a powerful force for social change, as shown by the ranks of those who have joined Greta Thunberg in the global climate movement. In addition to challenging political institutions and governments, young people today are also holding the corporate world accountable. To respond to young people’s expectations, brands, and organizations have turned to social media to interact and build relationships with them. However, critics have lamented that these attempts often fail and that young people’s trust in institutions, brands, and organizations continues to decline. This article asks how young people perceive organizational listenin…
Practice-based learning and innovation in nursing homes
2020
Purpose This paper aims to investigate the conditions under which learning and innovation occur within nursing homes by focusing on how the dynamics of the distribution and transformation of ideas and knowledge may be viewed as a prerequisite for innovation in both formal, planned learning situations and informal, everyday practices. Design/methodology/approach Data was produced via fieldwork, which included participant observations, conversations and research interviews with staff and managers at a Norwegian nursing home. The paper is inspired by situated learning theories and communities of practice, as the social context emerges as the site where learning and innovation are cultivated. …
Hvordan skapes rom for «omvendt deltakelse» i bærekraftig lokal samfunnsutvikling – aksjonsforskningens roller og bevegelser
2021
Det er økende oppmerksomhet på potensialer for borgeres engasjement i bærekraftig omstilling og lokaliseringen av FNs bærekraftsmål. Flere forsknings- og policyrapporter etterlyser bedre forståelse for hvordan bærekraft kan «oversettes» og implementeres i lokal planlegging og handling. Bærekraftig samfunnsomstilling krever bedre forståelser for hvordan offentlige/kommunale systemer kan samarbeide med borgerinitiativer – samtidig som de lokale initiativene bevarer selvstendighet og lokal forankring. I denne artikkelen tar vi utgangspunkt i en aksjonsforskningsprosess med borgerinitiativer i Oslo og ByKuben, Oslo kommunes senter for byøkologi. Vi utforsker hvordan det kan skapes rom for delta…
Der Gaius der Preußen
2011
The discovery of the Palimpsest of the Gaius' Institutions in 1816 occurred at the height of palimpsest research and is part of a broader controversy among German and Italian scholars at that time. The deciphering of the lower stratum of the palimpsest and its first publication was supported by the Preußische Akademie der Wissenschaften and was considered as a product of German intellectual spirit. The transcriptions were transferred to the Akademie der Wissenschaften and later to the Königliche Bibliothek of Berlin. Today they are preserved in the Staatsbibliothek zu Berlin. They still constitute an indispensable basis for the constitutio textus of Gaius' Institutions.
Modulation of voltage-gated K(+) channels Kv11 and Kv1 4 by forskolin.
2002
Forskolin (FSK) affects voltage-gated K + (Kv) currents in different cell types, but it is not known which of the various subunits form FSK-sensitive Kv channels. We compared the effect of the compound at Kv1.1 and Kv1.4 channels ectopically expressed in HEK 293 cells. Low FSK concentrations induced a phosphorylation-dependent potentiation of Kv1.1 currents. At higher concentrations, this effect was superimposed by a fast, cAMP-independent channel block. Kv1.4 currents were inhibited with lower potency by FSK but were not modified by phosphorylation. The variable effect of the compound might help to distinguish between Kv subunits expressed by native cells. 2002 Elsevier Science Ltd. All …
Pattern-Recognition: a Foundational Approach
2015
This paper aims at giving a contribution to the ongoing attempt to turn the theory of pattern-recognition into a rigorous science. In this article we address two problems which lie at the foundations of pattern-recognition theory: (i) What is a pattern? and (ii) How do we come to know patterns? In so doing much attention will be paid to tracing a non-arbitrary connection between (i) and (ii), a connection which will be ultimately based on considerations relating to Darwin’s theory of evolution.
Periopathogenic bacteria in dental plaque of Congolese patients with periodontitis : a pilot study
2018
Background Periopathogenic bacteria play an important role in the etiology of periodontal disease. At present, no study screening for periopathogens in the DR Congo was carried out. The aim of this pilot study was to investigate the prevalence of five periopathogens in Congolese patients with periodontitis and to determine the association between these bacteria. Material and Methods Twelve patients (eight women and four men) with a mean age of 45 ± 19 years from those consulted in dental services of two medical centers of Kinshasa from April 2017 to October 2017 were included. Full mouth examination was registered, the probing pocket depth and clinical attachment level were assessed at six …
Screening of antiinflammatory medicinal plants used in traditional medicine against skin diseases
1998
The antiinflammatory activity of twelve medicinal plants used against skin disorders were tested in different experimental models of topical inflammation and one in vitro inhibitory test against phospholipase A2 (PLA2) from Naja naja venom. Forsythia suspensa was the most active species on the arachidonic acid (AA) topical test. This last species together with Astragalus membranaceus and Ranunculus sceleratus were the most active on the 12-O-tetradecanoylphorbol-13-acetate (TPA) acute ear oedema test. Scrophularia auriculata was the most active on multiple topical applications of TPA and on the oxazolone-induced delayed type hypersensitivity (DTH). Santolina chamaecyparissus was the only sp…
