This article reports model experiments where vocal tract profiles of high and mid unrounded front and high rounded back vowels were systematically modified to simulate small constriction shifts along the hard or soft palate, in order to test A. M. Bell's century-old proposal that small shifts of tongue arch fronting or retraction would yield audible shifts of vowel timbre. Such differences were cl

We have addressed the importance of B cell tolerance to collagen type II, a matrix protein, which is a target in rheumatoid arthritis (RA) and its mouse models. We generated a germline-encoded anti-collagen type II (CII) IgH replacement anti-C1 B cell mouse strain (ACB) to investigate how B cell tolerance to CII, a matrix protein, is subverted and to further understand pathogenesis of RA. Phenotyp

Transcriptomics analysis revealed that genes involved in hepatic de novo cholesterol synthesis were down-regulated in fed HSL-null mice that had been on high-fat diet (HFD) for 6 months. This finding prompted a further analysis of cholesterol metabolism in HSL-null mice, which was performed in fed and 16-h fasted mice on a normal chow diet (ND) or a HFD regimen. Plasma cholesterol was elevated in

Data concerning the persistent reduction of flow velocities measured by transcranial color-coded sonography (TCCS) in relation to the clinical and radiological outcome among patients with ischemic events in middle cerebral artery (MCA) territory is scarce. Patients with > or = 50% reduction of peak systolic velocities (PSV-MCA) as compared to the contralateral MCA were prospectively included in fo

BACKGROUND: Primary hyperparathyroidism (pHPT) is associated with decreased bone density and increased fracture risk. A significant number of pHPT patients have low calcium intake and suffer from vitamin deficiency. Thus, we adopted a policy of postoperative supplements with calcium and vitamin D after parathyroid surgery. In this study, we investigated if this policy enhanced the postoperative in

This paper describes a driving simulator trial to evaluate driver reactions to a number of alternative information/ warning modes of a multi-modal system for the “safe speed and safe distance” concept. In 2006, eight Human Machine Interaction alternatives, consisting of a combination of visual, haptic and auditory modes were used alternatively to give information/warning to the driver on safe spee

The landscape composition in Sweden has drastically changed during recent years. Intensified farming and forestry has led to reduced areas valuable for biodiversity and a decline of biodiversity across many organism groups. In Sweden almost 30% of all day-living butterflies are considered threatened. Habitat creation as a by-product of anthropogenic activities may provide new habitats for species

Chitosan films for food packaging applications were prepared from shrimp and cricket chitosan, enriched with Schisandra chinensis extract. Physicochemical and antibacterial properties of the films were studied and compared with references studying similar chitosan films. Chitosan is a biodegradable polymer, mostly harvested from shells of crustaceans, which has been studied for packaging applicati

I alla industrier där partiklar behandlas i torra prover är segregering ett stort problem. Segregering kan ske vid olika steg i processen där partiklarna i fråga till exempel transporteras, blandas eller bara lagras. Det uppskattas att uppemot 30 % av all fördröjning i processer sker på grund av segregering av partiklar(Johanson, 2014). Detta leder till kritiska konsekvenser för ett företag så somSegregation is a well-known process problem that may cost companies quality and time. The aim of this project was to establish a fundamental understanding about sifting segregation by using the sifting segregation tester described in the ASTM International standard. In this work, Cellets and Suglets were used to study particles tendency to segregate at different weight ratios and different particl

Abstract The present thesis is concerned with the investigation of a metalorganic catalyst, a Pt complex used for C-C or C-N single bond formation in a cross coupling reaction. The investigated catalysts are used in a homogeneous reaction. In this study I have used chemical methods for the synthesis of the catalytic materials, a number of different techniques for the characterization of the catal

Vilken roll Hippocampus har i det episodiska minnessystemet är hett omdebatterat. En nylanserad teori, Competitive Trace Theory, stipulerar att strukturen ”kontextualiserar” minnen genom att skapa nya, multimodala minnesspår vid varje reaktivering av dem. Alla olika minnesspår har en gemensam, överlappande komponent samt en unik icke-överlappande komponent, och spåren konkurrerar om att slutligenThe role of the Hippocampus in episodic memory has been fervently discussed for a long time. A new model, titled ”Competitive Trace Theory”, holds that the role of this temporal lobe structure is to “contextualize” memory. This is achieved by the establishing of new, multi-modal memory traces every time the memory is reactivated. These distinct memory patterns all share a mutual component of the m

Syftet med detta examensarbete är att undersöka hur musiklärare praktiskt går tillväga för att sätta betyg och bedöma elever i ämnet musik på grundskolan. Detta eftersom jag upplever att detta inte har lärt mig detta i min utbildning och som musiklärare, eller lärare i allmänhet, är betygsättande en central del i arbetet. Jag har därför haft som mål att ta reda på vad som dokumenteras för de betygThe purpose of this study is to investigate how you practically do grading and assessment in the subject music at the elementary school level. This is because I think that I haven’t really learned this during my education and as a music teacher, or teacher in general, is grading an important part of the work. My goal has been to look at how mu-sic teacher’s document for the grades they give their

Today, technology is everywhere in our everyday lives whether it is wanted or not. The world has become digitalized and this development continues for each year that passes. The Swedish government has now (2018) updated the curricula for both kindergarten and elementary school to include more digital aspects in the teaching. With this background, this thesis (project) set out to design a digital a

One of the most difficult problems that an engineer who works with modeling deals with, is the question about how to translate a physical phenomenon into a set of equations. It is usually difficult to capture all dynamics and phenomena, so one usually strives for a set of equations that describes the physical system approximately and adequately with the accuracy for the purpose. In our case, we mo

Lysande protein ska hjälpa spåra ändringar vid alzheimers sjukdom Demens är ett syndrom som påverkar en stor del av populationen vid högre ålder. Syndromet yttrar sig genom att påverka personers kognitiva förmågor, huvudsakligen minnet. Frekvensen kommer fortsätta att öka med den åldrande populationen. Den vanligaste och mest välkända varianten av demens är alzheimers sjukdom. Som alla vet är deApolipoprotein E4 (ApoE4) is the biggest genetic risk factor for Alzheimer’s disease. While it is known to transport cholesterol to neurons the localization of the protein has not yet fully been mapped. Levels of amyloid precursor protein (APP) and its cleavage product amyloid beta (Aβ), the main component of amyloid plaques, in transfected cells were determined using western blot. Green fluoresce

This thesis addresses a project conducted in collaboration with Volvo Car Corporation, to develop a new concept for luggage covers in car luggage compartments. The purpose was to find a new concept, with focus on user friendliness and environmental sustainability, which automatically opens up for easy loading of the luggage compartment. The fabric in today's solution is made of polyester and P

In this thesis, dynamically controlled machine learning algorithms running on state of the art Arm microNPUs, with an attached Cortex-M CPU, were investigated. The machine learning framework used was Tensorflow and different subsets of it, such as Tensorflow Lite micro. Compiling the network to run on the microNPU was done with the use of an open-source compiler called, Vela. In order to investiga

An evaluative neutralisation process, whereby questionnaire items are phrased to be less evaluative, was used to create a new less socially desirable version of the social dominance orientation scale (SDO7). The main goal is to counteract the persistent floor effect which has affected the scale since its inception. The rationale behind the suggested correction is rooted with the problem of social

Water hardness is caused by magnesium and calcium ions (Mg2+ and Ca2+), and can result in formation of deposits, destruction of soap and increase of copper corrosion in old plumbing pipes. To soften the originally hard groundwater supplying 20% of Malmö’s drinking water, Bulltofta water treatment plant imports burned lime from Germany. Approximately 66 mg/L calcium is removed in the treatment plan
