Structure and dynamics in liquid bismuth and Bin clusters: A density functional study

2014

Density functional/molecular dynamics simulations with more than 500 atoms have been performed on liquid bismuth at 573, 773, 923, and 1023 K and on neutral Bi clusters with up to 14 atoms. There are similar structural patterns (coordination numbers, bond angles, and ring patterns) in the liquid and the clusters, with significant differences from the rhombohedral crystalline form. We study the details of the structure (structure factor, pair, and cavity distribution functions) and dynamical properties (vibration frequencies, diffusion constants, power spectra), and compare with experimental results where available. While the three short covalent bonds typical to pnictogens are characteristi…

Student participation in peer interaction : use of material resources as a key consideration in an open-ended problem-solving mathematics task

2021

This study explores how students deal with material resources in their peer interaction when working in pairs in an open-ended problem-solving task. The productive use of material resources can be expected to support successful peer work. However, research into social phenomena in peer interaction is needed in order to identify and describe productive and less productive forms of dealing with material resources as students participate in open-ended problem-solving tasks. Consequently, this explorative study responds to this research need. Based on multimodal data, including video recordings, transcribed talk and the written contributions from four pairs of Year 7 students aged 12-13 years, …

Taking non-manuality into account in collecting and analyzing Finnish Sign Language video data

2014

This paper describes our attention to research into non-manuals when collecting a large body of video data in Finnish Sign Language (FinSL). We will first of all give an overview of the data-collecting process and of the choices that we made in order for the data to be usable in research into non-manual activity (e.g. camera arrangement, video compression, and Kinect technology). Secondly, the paper will outline our plans for the analysis of the non-manual features of this data. We discuss the technological methods we plan to use in our investigation of non-manual features (i.e. computer-vision based methods) and give examples of the type of results that this kind of approach can provide us…

Short-term responses of Rana arvalis tadpoles to pH and predator stress: adaptive divergence in behavioural and physiological plasticity?

2022

Environmental stress is a major driver of ecological and evolutionary processes in nature. To cope with stress, organisms can adjust through phenotypic plasticity and/or adapt through genetic change. Here, we compared short-term behavioural (activity) and physiological (corticosterone levels, CORT) responses of Rana arvalis tadpoles from two divergent populations (acid origin, AOP, versus neutral origin, NOP) to acid and predator stress. Tadpoles were initially reared in benign conditions at pH 7 and then exposed to a combination of two pH (acid versus neutral) and two predator cue (predator cue versus no predator cue) treatments. We assessed behavioural activity within the first 15 min, an…

Viltotas preces – patērētāju izvēle un institūciju darbība pret to pieejamību tirgū

2021

Maģistra darba tēma ir “Viltotas preces – patērētāju izvēle un institūciju darbība pret to pieejamību tirgū”. Pētījuma mērķis ir novērtēt patērētāju izvēles ietekmējošos faktorus, apzināti izvēloties iegādāties viltotas preces, kā arī izvērtēt institucionālos aspektus cīņā ar viltojumu pieejamību Eiropas Savienības tirgū. Darbs strukturēts trīs nodaļās, aplūkojot patērētāju lēmumu pieņemšanas aspektus, viltojumu tirgus izplatības ekonomisko ietekmi, izpēti noslēdzot ar Latvijas patērētāju anketēšanas rezultātu apkopojumu un analīzi. Veicot analīzi secināts, ka Latvijas patērētāju galvenie iemesli, lai iegādātos viltotās preces ir to zemās cenas un informācijas trūkums par viltoto preču nega…

Design of a Virtual Learning Environment for Students with Special Needs

2006

The European Social Fund-supported Portland Partnership project developed a computer-based virtual learning environment (VLE) to benefit students with cognitive and physical disabilities. This system provided students with access to a suite of software programs to teach them basic/essential skills needed for everyday life and to use information and communications technology (ICT). The VLE can be customized to meet individual students’ needs by selecting an input device, adjusting its setting, or choosing a symbol set to support on-screen text. The learning programs within the VLE required careful design to make them stimulating and beneficial to students who have diverse health conditions a…

Are Virtues Shaped by National Cultures or Religions?

2012

The present paper examines the relative influence of religion and nation on conceptions of virtues. In a first study, conducted in the Netherlands, 926 respondents of different profession, age, sex, and religious background rank ordered a list of 15 virtues. A comparison of Dutch Muslims and non-Muslims showed a remarkably high resemblance in their ratings of virtues. Only faith was rated as being much more important by Muslims than by non-Muslims. In the second study, the influence of national cultures was examined. Adults (N = 795) from two culturally relatively similar countries, Germany and the Netherlands, and from Spain rated the same list of virtues. Crossnational differences between…

Pathogenic mechanisms of how human parvovirus breaks self-tolerance

2017

It is known that viral infections can cause acute, chronic, and autoimmune diseases (ADs). However, the mechanism of how a persistent viral infection contributes to ADs remains still unclear. In this thesis, pathological and immunological aspects of how common viruses can initiate autoimmunity were investigated, and human parvovirus B19 (B19V) was employed as a model virus. B19V non-structural protein 1 (NS1), a superfamily 3 (SF3) helicase, initiated DNA damage resulting in cellular apoptosis. The apoptotic bodies (ApoBods) induced by B19V NS1 were purified and characterized. These ApoBods contained viral NS1 proteins with modified autoimmune-associated self-antigens, e.g. DNA, Smith, Apol…

CVB3 VP1 interacts with MAT1 to inhibit cell proliferation by interfering with Cdk-activating kinase complex activity in CVB3-induced acute pancreati…

2021

Coxsackievirus B3 (CVB3) belongs to the genus Enterovirus of the family Picornaviridae and can cause acute acinar pancreatitis in adults. However, the molecular mechanisms of pathogenesis underlying CVB3-induced acute pancreatitis have remained unclear. In this study, we discovered that CVB3 capsid protein VP1 inhibited pancreatic cell proliferation and exerted strong cytopathic effects on HPAC cells. Through yeast two-hybrid, co-immunoprecipitation, and confocal microscopy, we show that Menage a trois 1 (MAT1), a subunit of the Cdk-Activating Kinase (CAK) complex involved in cell proliferation and transcription, is a novel interaction protein with CVB3 VP1. Moreover, CVB3 VP1 inhibited MAT…
