Programmering undersöks med en social semiotisk lins för att studera hur programmering kan bidra till meningsskapande i fysik. Analysen fokuserar på hur nya och dynamiska representationer kan skapas med hjälp av programmering och hur programmering tillåter studenter att undersöka och skapa egna modeller av fysikaliska fenomen. Detta beskrivs utifrån ett semiotiskt perspektiv och det semiotiska perProgramming is investigated with a social semiotic lens to study how programming can contribute to meaning-making in physics. The analysis focuses on how new and dynamic representations can be created with the help of programming and how programming allows students to investigate and create their own models of physical phenomena. This is described from a semiotic perspective and the semiotic persp

Background: Sensorimotor impairments of the upper limb (UL) are common after stroke, but there is a lack of evidence-based interventions to improve functioning of UL. Objective: To evaluate (1) the efficacy of sensory relearning and task-specific training compared to task-specific training only, and (2) the feasibility of the training in chronic stroke. Design: A pilot randomized controlled trial.

Purpose: The aim of this study is to explore teachers’ experience and understanding of classroom communication after participating in a speech-language pathologist (SLP) led in-service training on classroom communication. Method: This qualitative study used a focus group approach to explore how teachers describe their classroom communication. Twenty primary-school teachers participated. Thematic a

Objective: To overview the updated Swedish National Guidelines on Urothelial Carcinoma 2021, with emphasis on non-muscle-invasive bladder cancer (NMIBC) and upper tract urothelial carcinoma (UTUC). Methods: A narrative review of the updated version of the Swedish National Guidelines on Urothelial Carcinoma 2021 and highlighting new treatment recommendations, with comparison to the European Associa

Background and purpose — High alcohol intake is associated with increased risk of postoperative complications. Alcohol cessation intervention is recommended prior to elective surgery. We investigated short- and long-term effects of perioperative intensive alcohol intervention in relation to acute ankle fracture surgery.Patients and methods — 70 patients requiring ankle fracture surgery and consumi

Data philanthropy (DP) is a new but much-lauded phenomenon. Extant DP research has been either conceptual, exploratory, and/or qualitative. The present study seeks to examine the business value of data philanthropy to the donor firm. We use an event study method to analyze stock performance of public firms associated with data philanthropy activities to determine if a link exists. We find signific

Importance: The performance of bioprosthetic aortic valves is usually assessed in single valve models or head-to-head comparisons. National databases or registries offer the opportunity to investigate all available valve models in the population and allows for a comparative assessment of their performance. Objective: To analyze the long-term rates of reintervention, all-cause mortality, and heart

Objectives: We aim to define whether the timing of microaxial left ventricular assist device (IMLVAD) implantation might impact on mortality in acute myocardial infarction (AMI) cardiogenic shock (CS) patients who underwent primary percutaneous coronary intervention (PPCI). Background: Despite the widespread use of PPCI, mortality in patients with AMI and CS remains high. Mechanical circulatory su

The water channel aquaporin-5 (AQP5) is essential in transepithelial water transport in secretory glands. AQP5 is ectopically overexpressed in breast cancer, where expression is associated with lymph node metastasis and poor prognosis. Besides the role in water transport, AQP5 has been found to play a role in cancer metastasis, migration, and proliferation. AQP5 has also been shown to be involved

The emergence of COVID-19 has been changing in the world since 2020 and prompted social, cultural, and economic systems to adjust their structures, routines, and processes. The economic aspects of the pandemic appeared soon, and many industries changed their workflow and procedures through a mandatory or recommended quarantine. Knowing the impact of COVID-19 on different areas of construction proj

Near-field earthquake is one of the primary sources of ground motions that significantly affecting the structure's seismic response in its surrounding area containing pulse-long periods. The two popular and reliable approaches for the seismic investigation of structures are known as the force and displacement-based seismic design (FBD and DBD), extensively developed in the literature. In the prese

Urbanization growth and aging infrastructures necessitate new infrastructure construction projects in congested urban areas. Urban construction projects interrupt the regular on-road vehicle traffic flow that affects air pollution concentration in the adjacent areas. The project schedule, however, is a possible contributor to the air pollution which has been neglected to date. This research propos

The high vehicle congestion is the main contributing factor to air pollution originated from the engine's combustion in many urban areas. Grade separation projects have been used to solve this problem and have resulted in overall air pollution reduction in many cases. Many grade separation projects are constructed near sensitive urban locations accommodating susceptible individuals. This research

This thesis is mainly concerned with investigations of approximation problems on spaces of analytic functions on the unit disc in the complex plane, which naturally arise in connection to spectral problems of certain classes of linear operators acting on the spaces in question. For instance, quasi-nilpotency of certain analytic paraproducts on the Hardy spaces and on the Bergman spaces are investi

BACKGROUND AND OBJECTIVES: Curative treatment for locally advanced head and neck tumours often includes reconstructive surgery using a microvascular free flap. Effective recuperation is essential but may be impeded by postoperative donor site pain. The aim of this study was to evaluate the effects of a continuous popliteal block on postoperative pain after fibular graft harvesting.MATERIAL AND MET

Vertically aligned metal halide perovskite (MHP) nanowires are promising for various optoelectronic applications, which can be further enhanced by heterostructures. However, present methods to obtain free-standing vertically aligned MHP nanowire arrays and heterostructures lack the scalability needed for applications. We use a low-temperature solution process to prepare free-standing vertically al

Microbial stoichiometry has become a key aspect in ecological research as shifts in microbial C:N, C:P and N:P ratios upon nutrient addition are presumed to give insight into relative nutrient limitations for soil microorganisms–with far-reaching implications for biogeochemical processes. However, this expectation has never been tested against direct methods of microbial growth responses to nutrie

Two patterns of bacterial growth response upon drying and rewetting (DRW) of soils have previously been identified. Bacterial growth can either start increasing immediately after rewetting in a linear fashion (“type 1” response) or start increasing exponentially after a lag period (“type 2” response). The effect of repeated DRW cycles was studied in three soils with different response patterns aft
