Lipid-Mediated Relation between Tissue Factor Pathway Inhibitor Activity and Cardiovascular Risk Factors and Diseases in a Large Population Sample
2018
Abstract Background: Tissue factor pathway inhibitor (TFPI), a Kunitz-type serine protease, is a potent anticoagulant protein in the extrinsic coagulation pathway and acts by inhibiting both the FXa and the Tissue Factor-FVIIa complex. In contrast to total and free TFPI antigen levels, the reference values and clinical determinants of total TFPI activity have not yet been studied in detail in the general population. In the present study, we aim to identify the cardiovascular determinants for total TFPI activity and investigate its association with cardiovascular disease (CVD) and total mortality, in a population at large. Methods: For this study, the first 4779 subjects of the population-ba…
Evils of the Istanbul Convention. Discourse analysis of Latvian press publications (2016) = Los efectos negativos del Convenio de Estambul. Análisis …
2018
Abstract. The Council of Europe Convention on preventing and combating violence against women and domestic violence caused heated discussion both in society and media in Latvia. The controversy was caused because Convention is based on the understanding that violence against women is a form of gender-based violence that is committed against women because they are women. The discussion showed that there are various interpretations and misinterpretations of gender as a concept. As well as hostility towards gender equality interpreted as a propaganda against so called traditional family values. The mass media play an important role in shaping of public thought.The mass media today are the ma…
Investigation of buckling characteristics of cracked variable stiffness composite plates by an eXtended Ritz approach
2021
Abstract Variable Angle Tow (VAT) composite plates are characterized by in-plane variable stiffness properties, which opens to new concepts of stiffness tailoring and optimization to achieve higher structural performance for advanced lightweight structures where damage tolerance consideration are often mandatory. In this paper, a single-domain eXtended Ritz formulation is proposed to study the buckling behaviour of variable stiffness laminated cracked plates. The plate behaviour is described by the first order shear deformation theory whose generalized displacements, namely reference plane translations and rotations, are expressed via suitable admissible trial functions. These consist of a …
Shakedown analysis for a class of strengthening materials within the framework of gradient plasticity
2010
Abstract The classical shakedown theory is extended to a class of perfectly plastic materials with strengthening effects (Hall–Petch effects). To this aim, a strain gradient plasticity model previously advanced by Polizzotto (2010) is used, whereby a featuring strengthening law provides the strengthening stress, i.e. the increase of the yield strength produced by plastic deformation, as a degree-zero homogeneous second-order differential form in the accumulated plastic strain with associated higher order boundary conditions. The extended static (Melan) and kinematic (Koiter) shakedown theorems are proved together with the related lower bound and upper bound theorems. The shakedown limit loa…
Shakedown of elastic—plastic solids with frictionless unilateral contact boundary conditions
1997
Abstract Elastic perfectly plastic solids (or structures) in frictionless unilateral contact with a rigid obstacle and subjected to quasi-statically variable loads within a given domain are considered. In the hypothesis that the structure undergoes small displacements and complies with a d -stability requisite herein introduced, a Melantype shakedown theorem is presented. This theorem is conceptually similar to the classical one; namely, it requires that the unilateral-contact elastic stress response to the loads and to some initial plastic strains be plastically admissible everywhere in the body and for all load conditions. A method for evaluating the shakedown load boundary is also discus…
How do Members of Parliament View the Public Value of Public Service Media? The Case of Latvia
2013
Abstract The Development of public media in Latvia as a post-communist country has essentially been influenced by politicians. The political community has had consensus that certain reforms are necessary to ensure the development of public media given the changes in the communication space and its role in the facilitation of the strengthening of democracy, yet during the last fifteen years the political elite has not been able to come to a common agreement and to make decisions on systemic reforming and the development of public media. Since the communication environment has changed post digitalisation of television, the question about public media development and legitimisation has become …
The Impact of Solar Penetration on Solar and Gas Market Value: An Application to the Italian Power Market
2014
We assess the impact of solar penetration in the Italian wholesale electricity market on the market value of solar with respect to gas sources, measured as the ratio between the relative price they respectively earn and the average daily electricity price (value factor). We find that, on average, an increase of solar generation has a negative impact on the price earned by solar producers, thus causing a marginal departure from the grid parity condition. The relation between solar production and its market value is not constant over the years, while it depends on the degree of solar penetration. It is positive for very low levels of solar production while, as production increases, its margin…
Tooth discoloration and internal bleaching after the use of ledermix paste with various bleaching agents ? An in vitro study
2018
Background To assess the reversal of discolouration caused by Ledermix using various bleaching agents. Material and Methods Twenty six extracted human mandibular premolars were taken and divided into four groups. Six teeth were divided into three each which are taken as positive and negative controls. The remaining twenty are divided into two groups (n=10). After conventional access preparation, the Ledermix paste was sealed in the pulp chamber for twelve weeks. The paste was removed by a rinse with sodium hypochlorite (NaOCl). Then the pulp chamber was sealed with a mixture of Sodium perborate and distilled water for group 1 and group 2 was sealed with Sodium tetraborate for 1 to 12 weeks.…
No public value without a valued public
2017
This study aims to enlighten the controversial discussion about the term public value in an innovative way. Instead of normative pronouncements and paternalistic posits, this study combines a theoretical, literature-based conception with an empirical quantitative approach. For this, the key term, public value, is split into its constituent parts of customer value and citizen value and is transformed into measurable attributes. By means of a choice-based conjoint analysis on panel data for Germany and the United Kingdom, we explore which performance attributes of public service broadcasters are the most important. Based on the results, we create a conception of public value from the perspect…
Large-eddy simulations of turbulent flow with heat transfer in simple and complex geometries using Harwell-FLOW3D
1996
Abstract Large-eddy simulation (LES) results are presented and discussed for the turbulent flow with heat transfer in different geometrical configurations, including a plane channel, a channel bearing transverse square ribs on one of the walls, and a crossed-corrugated air heater. They were obtained using the computational fluid dynamics (CFD) code Harwell-FLOW3D (Release 2), finite-volume grids having up to 423 nodes, and the Smagorinsky subgrid model with several variants regarding near-wall damping and wall boundary conditions. The first problem (plane turbulent Poiseuille flow with heat transfer) was mainly used as a benchmark to investigate the influence of numerical methods (pressure-…
