Making sense of chemical equilibrium : productive teacher-student dialogues as a balancing act between sensemaking and managing tension

Navigating the observational, symbolic, and theoretical knowledge domains of chemistry is crucial for chemistry sensemaking. However, this has been shown to be particularly challenging for students of chemistry. In order to reach government standards for sensemaking in the chemistry subject, it is important to investigate how chemistry teachers can sustain sensemaking practices in their classrooms

The language of sound : events and meaning multitasking of words

The focus of much sensory language research has been on vocabulary and codability, not how language is used in communication of sensory perceptions. We make a case for discourse-oriented research about sensory language as an alternative to the prevailing vocabulary orientation. To consider the language of sound in authentic textual data, we presented participants with 20 everyday sounds of unknown

Advances in automatic identification of flying insects using optical sensors and machine learning

Worldwide, farmers use insecticides to prevent crop damage caused by insect pests, while they also rely on insect pollinators to enhance crop yield and other insect as natural enemies of pests. In order to target pesticides to pests only, farmers must know exactly where and when pests and beneficial insects are present in the field. A promising solution to this problem could be optical sensors com

Andra världskriget som intern(et)skämt : En studie om kulturell gemenskap på forumet r/ww2memes

I denna masteruppsats undersöks hur internetmemes om andra världskriget används på det Reddit-baserade forumet r/ww2memes för att bilda gemenskap. Eftersom internetmemes ofta saknar upphovsperson och tydligt ursprung studeras de här som allmänna kulturella fenomen, tillkomna genom deltagande på forumet, vilka genom humor ger uttryck för historiesyn och gemenskap. I syfte att genomföra studien har World War II as an in(ternet)-joke : A study on cultural community on the forum r/ww2memes. This master’s thesis examines the construction of community on the Reddit-forum r/ww2memes, dedicated to publishing and sharing internet memes concerning World War 2. By constructing a theoretical framework consisting of a certain use of history applied in presentist temporalities, herein referred to as ap

LPS priming before plaque deposition impedes microglial activation and restrains Aβ pathology in the 5xFAD mouse model of Alzheimer's disease

Microglia have an innate immunity memory (IIM) with divergent functions in different animal models of neurodegenerative diseases, including Alzheimer's disease (AD). AD is characterized by chronic neuroinflammation, neurodegeneration, tau tangles and β-amyloid (Aβ) deposition. Systemic inflammation has been implicated in contributing to the progression of AD. Multiple reports have demonstrated uni

Traditional and Disease-Specific Risk Factors for Cardiovascular Events in Antineutrophil Cytoplasmic Antibody-Associated Vasculitis : A Multinational Retrospective Study

Objective. To investigate the occurrence of cardiovascular events (CVEs) in a large cohort of patients with antineutrophil cytoplasmic antibody (ANCA)-Associated vasculitis (AAV) across the European Union, China, Turkey, Russia, the United Kingdom, and the USA. Methods. Patients with a definite diagnosis of AAV who were followed for ? 3 months and had sufficient documentation were included. Data o

Learning to Control the Cloud

With the growth of the cloud industry in recent years, the energy consumption of the underlying infrastructure is a major concern.The need for energy efficient resource management and control in the cloud becomes increasingly important as one part of the solution, where the other is to reduce the energy consumption of the hardware itself.Resource management in the cloud is typically done using rel

Crumbs from the Rich Man's Table? : Municipal Labour Market Policies and Recognition of Welfare Recipients in Sweden

Labour market policies, also known as activation, are common responses to poverty, unemployment and social exclusion. Activation is characterised by increased individual responsibility, requiring welfare recipients to strive for financial self-sufficiency, be it through job-seeking, training or coaching. In Sweden, activation policies are also implemented in municipal welfare services such as soci

Predicting tool life for side milling in C45 E using Colding and Taylor tool life models

This paper investigates the possibility of using empirical tool life models to predict tool life in a side milling application in a medium carbon steel, C 45E. To do this, an extensive dataset containing 46 data points with different machining parameters are produced. Four different empirical models: Taylor's equation, Colding's equation and Extended Taylor both using depth of cut and feed as well

Dysfunctional mucociliary clearance in asthma and airway remodeling – New insights into an old topic

Bronchial asthma is a heterogeneous respiratory condition characterized by chronic airway inflammation, airway hyperresponsiveness and airway structural changes (known as remodeling). The clinical symptoms can be evoked by (non)specific triggers, and their intensity varies over time. In the past, treatment was mainly focusing on symptoms’ alleviation; in contrast modern treatment strategies target

Acquired uterine arteriovenous malformation—Does it really exist? A case report

Acquired arteriovenous malformations (AVM) of the uterus can cause life-threatening vaginal bleeding and are associated with previous pregnancy, abortion or pelvic trauma. The pathophysiology is not well understood and the diagnosis is usually made by greyscale ultrasound often with nonspecific imaging findings, hence making it difficult to establish a correct diagnosis and therefore also the true

Obesity and breast cancer prognosis : pre-diagnostic anthropometric measures in relation to patient, tumor, and treatment characteristics

PURPOSE: Examine the association between obesity and clinical outcomes in early breast cancer and assess if patient, tumor, and treatment characteristics modify such associations in Malmö Diet and Cancer Study patients (MDCS).METHODS: The MDCS enrolled 17,035 Swedish women from 1991 to 1996. At enrollment, participants' body mass index (BMI), waist circumference and body fat percentage measures we

Improving Image Stabilization in Modern Surveillance Cameras

This thesis investigates potential ways to improve the image stabilization in Axis Communications surveillance cameras. The current in-house developed stabilization algorithm, Axis EIS, stabilizes based on gyroscope measurements. We compare a purely gyroscope based stabilization algorithm with a gyroscope-accelerometer sensor fusion stabilization algorithm, image-based stabilization algorithms and

Pathogen-driven degradation of endogenous and therapeutic antibodies during streptococcal infections

Group A streptococcus (GAS) is a major bacterial pathogen responsible for both local and systemic infections in humans. The molecular mechanisms that contribute to disease heterogeneity remain poorly understood. Here we show that the transition from a local to a systemic GAS infection is paralleled by pathogen-driven alterations in IgG homeostasis. Using animal models and a combination of sensitiv
