Sammanfattning: En resultant-identitet för polynom i en variabel bevisas och används för att karakterisera SAGBI-baser för underalgebror genereradeThe thesis consists of an introduction and the following four papers: Paper I: Using resultants for SAGBI basis verification in the univariate polynomial ring. Authors: Anna Torstensson, Victor Ufnarovski and Hans Öfverbeck. Abstract: A resultant-type identity for univariate polynomials is proved and used to characterise SAGBI bases of subalgebras generated by two polynomials. A new equivalent

The combination of features from the public and private sectors in jointly owned companies imposes challenges to the governance and control mechanisms of these organisations, which have been criticised for lacking accountability. Where there is fragmented ownership, the interests of different owners need to be coordinated. The aim of this article is to consider how such companies can be governed i

Lake Poopó is a terminal lake of the Bolivian Altiplano, with high salinity and heavy anthropogenic pollution from centuries of extensive mining activity. This study aims to describe how the water quality of groundwater and surface water system in different subwater-sheds of the Lake Poopó varies with geology and hydrology. Measurements of total dissolved solids (TDS) in wells show groundwater bec

The Swedish word folk ('people') is normally considered an ordinary noun. This classification is, however, not completely unproblematic, since it is sometimes claimed that folk is actually undergoing a word-class change, becoming more and more pronoun-like. Similar changes from noun to generic pronoun are also attested for words with the meaning ‘people’ in other languages, making this a possible

This thesis concerns the role of disability and assistive devices in everyday life among persons with, for instance, impairments related to mobility (e.g. wheelchair users) and bodily shape and configuration (e.g. dysmelia). Assistive devices are seen as both includators (assisting participation and emancipation) and excludators (limiting participation, restraining empowerment, and stigmatizing).

The present report from the ESE Educational Program on Parathyroid Disorders (PARAT Program) presents recent developments and novelties in the clinical care of parathyroid disorders in a question-and-answer format, based on a satellite workshop held in relation to the European Congress of Endocrinology in Stockholm, May 2024. The workshop focused on clinical aspects of 3 main themes: primary hyper

Föroreningar av mark- och vattenområden, så kallade föroreningsskador, medför i regel höga kostnader att avhjälpa. För att undvika att kostnaden belastar statsbudgeten har ett avhjälpandeansvar införts i 10 kap. miljöbalken, enligt vilket i första hand verksamhetsutövare har ett ansvar för utredning, efterbehandling och andra åtgärder som krävs för att avhjälpa en föroreningsskada. VerksamhetsutövAfter-treatment of polluted land or water areas usually entails high costs. To avoid that the cost burdens the state budget, an after-treatment liability was introduced in chapter 10 of the Environmental Code, according to which operators primarily shall be liable for the cost of investigation, after-treatment and other measures required to remedy the pollution damage. As a general rule, the conce

In recent years, researchers worldwide have become increasingly interested in the phenomenon of code-switching in the multilingual classroom. The paper aims to try to understand when and why teachers in Swedish for Immigrants (SFI) schools code-switch in their classrooms. It analyses the methods and reasons for teachers’ code-switching in the SFI classroom. A case study was conducted by means of a

This study focuses on the introduction of new nuclear, particularly Small Modular Reactors (SMRs) in Sweden. The Swedish Government has decided on a revival for nuclear energy where SMRs are an important contribution to reach the goal of a total output of at least 2 500 MW by 2035. In this stage when much is unclear about the re-introduction and SMRs are under development media is an important age

This paper investigates resilient performance of Air Traffic Management with future Artificial Intelligence (AI)-based tools. A case study was performed on an early prototype of an AI-enabled Flight Information Service (FIS) tool, using a survey of flight instructors and air traffic controllers, and a focus group with controllers with flying experience. The study focused on what characterizes good
