  English abstract:

  This chapter focus on fire symbolism in ritual practices ands in ritual speech among the Yucatec Maya seen in a long term perspective. The main sources in this chapter are Early Colonial documents and Yucatec Maya manuscripts such as the Books of Chilam Balam and the Ritual of the Bacabs. Important new data also comes from the ethnographic Collection from the Swedish Prince Wilhelms journey to the Maya area in 1920.

  English abstract:

  We previously reported that CaCl2 hydrothermal-treated (Ca-HT) titanium (Ti) implants induced a tight sealing at the interface between the implant and peri-implant epithelium (PIE) after implantation. However, it is not clear how long this improved epithelium sealing can be maintained. We subsequently investigated whether the positive effect of Ca-HT to promote sealing between the PIE and implant was sustained longer term. Maxillary molars were extracted from rats and replaced with either Ca-HT implants (Ca-HT group), distilled water-HT implants (DW-HT group) or non-treated implants (control group). After 16 weeks, the majority of implants in the Ca-HT group remained at the maxillary with no apical extension of the PIE. Conversely, half the number of control implants was lost following down-growth of the PIE. The effect of Ca-HT on migration and proliferation of rat oral epithelial cells (OECs) was also investigated. In OECs cultured on Ca-HT Ti plates, protein expression in relation to cell migration decreased, and proliferation was higher than other groups. Surface analysis indicated HT enhanced the formation of surface TiO2 layer without altering surface topography. Consequently, Ca-HT of Ti reduced PIE down-growth via tight epithelial attachment to the surface, which may enhance implant capability for a longer time post-implantation.

• Vem ansvarar för klimatkrisen? En studie om hur svenska nyhetstidning...
  Morner, Filippa  : Malmö universitet/Kultur och samhälle (2019)	Bachelor thesis

  

  

  English abstract:	This study examines the part that Swedish newspapers play in the context of constructing responsibility for the climate crisis in Swedish society. This is done by studying how two of the biggest newspapers in Sweden, Dagens Nyheter and Aftonbladet, portray different actors’ responsibilities in the climate crisis in their news articles. It is of high relevance to study newspapers’ distribution of responsibility since previous research has shown that news media can affect both the perception of events and topics in society, as well as attitudes and behaviours in regards to those events and topics. Therefore, this study aims to contribute to a better understanding of how the newspapers’ distribution of responsibility can affect the perception of responsibility as well as the management of the climate crisis in the Swedish society. The material is analyzed through the theory of framing and the environmental communication research’s view that communication about the environment shapes the perception and therefore the form of the environment. The result shows that news articles mainly give responsibility to political actors, that companies’ responsibility is pushed over to political actors or placed between both companies and political actors where companies get the lesser responsibility, and that individuals are given a minimal amount of responsibility. The main conclusion is that the newspapers do not distribute responsibility evenly among the essential actors, which can be seen as problematic since climate research mean that all actors in society must act to solve the climate crisis.
  Swedish abstract:	Den här studien undersöker nyhetstidningarnas del i kontexten för hur ansvar för klimatkrisen formas i det svenska samhället. Detta görs genom att studera hur två av de största nyhetstidningarna i Sverige, Dagens Nyheter och Aftonbladet, framställer olika aktörers ansvar för klimatkrisen i sina nyhetsartiklar. Det är relevant att studera nyhetstidningarnas ansvarsbeläggning för klimatkrisen då tidigare forskning har visat att nyhetsmedier kan påverka både uppfattningen om ämnen i samhället samt attityder och beteenden i relation till de ämnena. Studiens avsikt är därför att bidra till förståelse för hur nyhetstidningarnas ansvarsbeläggning av klimatkrisen kan påverka uppfattningen om ansvar och således hanteringen av klimatkrisen i samhället. Materialet analyseras utifrån gestaltningsteorin och miljökommunikationsforskningens syn på miljökommunikation som formande av miljön. Resultatet visar på att artiklarna till störst del ansvarsbelägger politiska aktörer, att företags ansvar förskjuts till politiska aktörer eller fördelas mellan politiska aktörer där företagen då får minst ansvar, samt att individers ansvar knappt gestaltas. Slutsatsen är att nyhetstidningarna inte ansvarsbelägger väsentliga aktörer i klimatkrisen lika mycket, vilket kan ses som problematiskt då klimatforskning menar att alla aktörer i samhället måste agera.

• Multimodal Sensory Stimulation of the Masseter Muscle Reduced Precisi...
  Wiesinger, Birgitta; Häggman-Henrikson, Birgitta; Eklund, Anton; Wänman, Anders; Hellström, Fredrik   Journal article in Frontiers in Neuroscience; : Frontiers (2019)	Journal article

  

  

  English abstract:

  A functional integration between the trigeminal and craniocervical sensorimotor systems has been demonstrated, with simultaneous jaw and head-neck movements during jaw opening-closing. We previously showed that pain induction in the masseter muscle increased the relative contribution of the neck component of integrated jaw-neck movements. Induced pain or manipulation of proprioception by vibration did not affect accuracy during a jaw-opening task in men. It is not known how multimodal sensory stimulation, with a combination of pain induction and vibration, affects jaw-opening accuracy and precision. The aim was to investigate how jaw-neck movements, and specifically accuracy and precision of jaw-opening, are affected during concomitant nociceptive and proprioceptive stimulation of the masseter muscle. Twenty-one healthy men performed jaw-opening to a target position, defined as 75% of individual maximum jaw opening, during control (Ctr), vibration of masseter muscles (Vib), pain induction in the masseter (Pain), and concomitant vibration and pain induction in the masseter muscle (VibPain). Simultaneous jaw and head movements were recorded with an optoelectronic system and amplitudes calculated for each jaw opening-closing cycle. Accuracy of jaw movements was defined as the achievement of the target position. Precision of jaw movements was defined as the cycle-to-cycle variability from the mean of cycles 2-10 (coefficient of variation, CV). Differences between the trials were analyzed with Friedman's test, Dunn's test, and Benjamini-Hochberg correction. There were no significant differences between the trials for jaw movement amplitudes. For head movements, amplitudes for cycles 2-10 were larger during Pain compared to Ctr and Vib (both p = 0.034), and larger during VibPain compared to Ctr (p = 0.034) and Vib (p = 0.035). There were no differences in accuracy of jaw movements between the trials. For precision of jaw movements, the cycle-to-cycle variability was larger during VibPain compared to Ctr (p = 0.027) and Vib (p = 0.018). For integrated jaw-neck motor strategy, there was a difference between pain and non-pain trials, but no differences between unimodal and multimodal stimulation trials. For achievement of jaw-opening to a target position, the results show no effect on accuracy, but a reduced precision of jaw movements during combined proprioceptive and nociceptive multimodal stimulation.

  Marcelino, Leonardo; Sjöström, Jesper; Marques, Carlos Alberto   Review article in Sustainability; : MDPI (2019)	Review article

  

  

  English abstract:

  The current research on systems thinking criticizes the additive nature of green chemistry (GC) not being supportive of systems thinking to achieve holism in its practices. This paper argues that systems thinking should comprise of the social issues, and, therefore, it studies renowned papers by GC pioneers and reviews on the field regarding how they address the social dimension of sustainability. It points out how GC has ignored social sustainability in its discourses, practices, and evaluations, leading to a reductionist interpretation of sustainability. Then, this paper presents some challenges to be overcome in order to achieve balanced sustainability. A systemic chemical thinking is advocated, considering chemistry in culture and chemistry as culture, expanding the chemistry rationality from ontological and technological dimensions into the epistemological and ethical ones. It is then discussed how chemistry education can help to promote sustainability in a broad and systemic way.
