Mikołaj Rej o Fortunie Łudarce i Zwodnicy oraz o "świeckiej krotochwili"
2018
Tematem artykułu jest problematyka związana z zagadnieniem Fortuny w twórczości Mikołaja Reja. Motyw ten w literaturze i sztuce przybierał rozmaite kształty i konwencje. Fortuna w utworach Reja raz jawiła się jako bogini, kiedy indziej jako demon. Pisarz chętnie też sięgał po konwencję teatru świata, sceny cyrkowej, będącej domeną bogini Circe, turniejów czy pola walki. Jednak źródłem tych wszystkich metafor okazały się złożone relacje łączące plan Opatrzności z porządkiem natury, które dotyczyły uprzywilejowanego miejsca człowieka we wszechświecie. Dychotomiczność ludzkiej natury widoczna w rozróżnieniu na los i fortunę znalazła w twórczości Reja, wspartej na gruncie humanizmu chrześcijańs…

Imunitātes stiprinošu minerālvielu lietošana un aprite aptiekā laika posmā no 2021. gada 1. janvāra līdz 2022. gada 1. martam
2022
Minerālvielu piedevas ir visbiežāk lietotie uztura bagātinātāji visā pasaulē. Aptiekas klienti katru dienu iegādājas minerālvielas pie dažādām sūdzībām. Galvenie iemesli minerālvielu lietošanai ir nogurums, nespēks, pazemināta imunitāte un nervu sistēmas traucējumi. Darba mērķis bija salīdzināt minerālvielu pieprasījumu par periodu no 2021.gada 1. janvārim līdz 2022.gada 1. martam, kā arī noskaidrot, kādas minerālvielas cilvēki lieto visbiežāk un kāpēc izvēlās tieši tos. Darba uzdevumi bija izanalizēt minerālvielu apgrozījumu vienā no aptiekām, kura atrodas Rīgā, Ziepniekkalna rajonā, par periodu no 2021. gada 1. janvārim līdz 2022. gada 1. martam, noskaidrot, kuras minerālvielas ir vispiep…
Public health policies and alcohol-related liver disease
2019
Summary: Alcohol-related liver disease (ALD) represents a major public health problem worldwide. According to the World Health Organization, the highest levels of per capita alcohol consumption are observed in countries of the European Region. Alcohol consumption is also alarmingly increasing in developing countries. ALD is one of the main contributors to the burden of alcohol-attributable deaths and disability. In the United States, severe forms of ALD such alcoholic hepatitis have increased in the last decade and in the United Kingdom, three-quarters of liver-related mortality results from alcohol consumption. Besides genetic factors, there is strong evidence that the amount of alcohol co…
An Iranian booklet: non destructive examination by Energy Dispersive X-Ray Diffractometry and Micro-Raman Spectroscopy
2009
Energy Dispersive X-Ray Diffractometry was used in combination with micro-Raman Spectroscopy to study an undated illuminated Iranian booklet. In both cases, no preliminary preparation of the samples was needed: the data were acquired in a non-destructive way in a natural environment. The book is of particular interest because of the unusual presence of miniatures on some pages. The two techniques were used to collect data from small areas of the pages and in different regions of the miniature in order to identify inks and pigments and to attempt chronological assignment. Raman spectra were affected by strong background fluorescence. In spite of this, different peaks were detected and identi…
Micromechanical Properties and Collagen Composition of Ruptured Human Achilles Tendon
2012
Background:The Achilles tendon is one of the strongest tendons in the human body, and yet it frequently ruptures, which is a substantial clinical problem. However, the cause of ruptures remains elusive.Hypothesis:Ruptured human Achilles tendon displays inferior biomechanical properties and altered collagen composition compared with noninjured tendon.Study Design:Controlled laboratory study.Methods:Biopsy specimens were obtained at the rupture site and the noninjured part of the tendon (internal controls) in 17 patients with acute Achilles tendon rupture. Age- and weight-matched human cadaveric Achilles tendons (external controls) were also obtained. Tendon samples were tested micromechanica…
Intrinsic spin-orbit interaction in diffusive normal wire Josephson weak links: Supercurrent and density of states
2016
We study the effect of the intrinsic (Rashba or Dresselhaus) spin-orbit interaction in superconductor–nanowire–superconductor (SNS) weak links in the presence of a spin-splitting field that can result either from an intrinsic exchange field or the Zeeman effect of an applied field. We solve the full nonlinear Usadel equations numerically [The code used for calculating the results in this paper is available in https://github.com/wompo/Usadel-for-nanowires] and analyze the resulting supercurrent through the weak link and the behavior of the density of states in the center of the wire. We point out how the presence of the spin-orbit interaction gives rise to a long-range spin triplet supercurr…

Energy Drink Consumption Among Finnish Adolescents: Prevalence, Associated Background Factors, Individual Resources, and Family Factors.
2020
Objectives: Energy drink consumption among adolescents has become a notable global phenomenon, and has been associated with numerous negative health outcomes. In order to understand the popularity of energy drinks among adolescents, and to target interventions, it is important to identify the determinants underpinning consumption. Methods: The nationally representative data (cross-sectional) were drawn from the Health Behaviour in School-aged Children (HBSC) surveys, conducted in 2014 and 2018, each comprising 13- and 15-year-old Finnish adolescents (n = 7405). Results: Weekly energy drink consumption increased among Finnish adolescents between 2014 (18.2%) and 2018 (24.4%), especially amon…
The micro-macro link in understanding sport tactical behaviours: Integrating information and action at different levels of system analysis in sport
2015
Les liens micro-macroscopiques sont centraux dans les sciences du mouvement humain dans la mesure ou ils correspondent aux coordinations et aux echelonnages des comportements moteurs a differents niveaux d’analyse des systemes complexes. Cet aspect de la complexite est un point cle permettant de considerer decision et action comme un comportement de transition a differents niveaux lors de la realisation d’une performance. Les transitions exprimees en termes de bifurcations sont une part importante du mecanisme universel de decision. Les transitions de phase fournissent aussi un moyen de comprendre les liens micro-macro. Dans cet article de synthese, nous developpons un point de vue qui expl…
