Optical properties of soot have been investigated with and without potassium chloride (KCl) salt added to the soot formation process in a premixed ethylene/air flame. A strong decrease in optical absorption efficiency of the soot was observed with increasing amounts of KCl added to the fuel based on the method of fluence curve analysis using laser-induced incandescence (LII). To understand the rea
Introduction Health technology assessment (HTA) is an area that remains less implemented in low- and lower middle-income countries. The aim of the study is to understand the perceptions of stakeholders in Uganda toward HTA and its role in decision making, in order to inform its potential implementation in the country. Methods The study takes a cross-sectional mixed methods approach, utilizing an a
Endocrine disrupting compounds (EDC) have the potential to seriously impact ecosystems and humans. To date, numerous techniques have been investigated for removing such contaminants from water, including biodegradation, photocatalysis, ozonation, and the Fenton process. However, these methods are expensive from the perspectives of equipment and operating costs. Herein, we investigated the use of e
OBJECTIVES: Hexavalent chromium (Cr(VI)) is classified as a human carcinogen. Occupational Cr(VI) exposure can occur during different work processes, but the current exposure to Cr(VI) at Swedish workplaces is unknown.METHODS: This cross-sectional study (SafeChrom) recruited non-smoking men and women from 14 companies with potential Cr(VI) exposure (n = 113) and controls from 6 companies without C
Osmotic forces are important in regulating a number of physiological membrane processes. The effect of osmotic pressure on lipid phase behavior is of utmost importance for the extracellular lipids in stratum corneum (the outer part of human skin), due to the large gradient in water chemical potential between the water-rich tissue on the inside, and the relative dry environment on the outside of th
Substructure coupling and model order reduction using Component Mode Synthesis (CMS) have, over recent years, gained considerable attention in the vibroacoustic analysis of complex structures. In the CMS methodology, the interior dynamics of each subcomponent in a substructured system are represented by a truncated set of normal modes within the lower frequency range, while all physical degrees of
In most non-fullerene organic solar cells comprising bulk-heterojunction active layers, the inter-domain connectivity of small-molecule acceptors is generally inferior to those of polymeric donors due to their intrinsic short-range ordering. This issue is even exacerbated by the physiochemical mismatch between acceptor-phases and metal-oxide electron transport layers in most inverted n-i-p devices
Telomeres are the ends of linear eukaryotic chromosomes. The telomeres are essential for solving the end replication problem and they stabilize the genome by protection from degradation. The telomeres also protect the chromosomal ends from by being recognized as DNA breaks by the repair machinery, which could lead to end-to-end fusions. Dysfunctional telomeres are implicated in many complex cellul
Reactions of 4-thio-2′-deoxyuridine d(s4U) and 4-thiouridine 5′-monophosphate s4UMP with trans-[AuY2Cl2]+/– (Y = CN– or NH3) have been investigated by conventional and high-pressure stopped-flow spectrophotometry in aqueous solution with 2.9 ⩽ pH ⩽ 7.0. For a given combination of metal complex and sulfur donor the observed second-order rate constants decreased with increasing pH. In the pH range 2
In a previous study, in order to investigate the effect of charge stratification on combustion behavior such as combustion efficiency and combustion phasing which also largely affects the emissions, an experiment was conducted in a heavy-duty compression ignition (CI) metal engine. The engine behavior and emission characteristics were studied in the transition from HCCI mode to PPC mode by varying
Abstract Title: Maximizing Value-to-Effort using Digital Twins in a Rapidly Moving Supply Network Authors: André Laurent – Hedlund & Oskar Helén Cedergren Supervisors: Sandeep Jagtap, Senior Lecturer at Engineering Logistics, Faculty of Engineering (LTH) at Lund University Digitalization Manager at The Company Examiner: Andreas Norrman, Professor at Engineering Logistics, Faculty of Enginee
This study explores the relationships between voltage, temperature, and consumed life in silicon carbide (SiC) MOSFETs using symbolic regression as a data-driven tool for deriving interpretable equations. The data comes from an accelerated life-time test performed by RISE. The symbolic regression model was implemented using the open source program ”PySR”. Since real experimental data were used, cl
Inconel 718 is a widely used Nickel-based alloy in the aerospace sector. However, its exceptional mechanical properties make it a very difficult material for machining operations. Additive manufacturing presents itself as a promising alternative, as it would reduce the need for post-printing material removal by machining. However, not enough research has been done about the behaviour of this mater
The study of heterogeneous catalysis has important implications in increasing the efficiency of industrial processes and in reducing the emissions of greenhouse gases from sources such as automobiles. A reaction with high industrial relevance is the oxidation of CO on noble metal catalysts. In this work I apply Fourier Transformations to Ambient Pressure X-ray and Ultraviolet Photoelectron Spectr
I detta arbete har en Minimum viable product (MVP) för en applikation utvecklats, som gör det säkrare att avveckla och ta bort endpoints för ett REST API. Tidigare arbete har visat att hanteringen av avvecklingen av endpoints i REST API:er är ett problem, där REST API:er inte följer protokoll för avveckling och borttagning. Applikationen är gjord för att tillhandahålla ett enkelt sätt att övervakaIn this thesis - a Minimum viable product (MVP) for an application aimed at making deprecation and removal of REST API endpoints safer - was developed. Previous work has shown that handling deprecations and removal of endpoints in REST APIs is a problem, with REST APIs not following deprecation-removal protocols nor giving the API consumers the information needed to properly update their software.
Våld i nära relationer, och då främst mäns våld mot kvinnor, utgör ett erkänt samhällsproblem. En särskilt utsatt grupp är våldsutsatta kvinnor med osäker uppehållsrätt som kommit till Sverige på anknytning till en svensk man. Kvinnorna får tidsbegränsade uppehållstillstånd och om anknytningen bryts föreligger inte längre förutsättningar för uppehållstillståndet, och kvinnan utvisas. Om kvinnan kaDomestic violence, and primarily men's violence against women, is a well-recognized social problem. A particularly vulnerable group is abused women with uncertain right of residence. Their migration status depends on that of their spouse, and they receive only a temporary residence permit. If the relationship is broken, the conditions for the residence permit are no longer present and the woma
The present research seeks to understand interviews I have conducted with selected individuals in Budapest, Hungary. Through an analysis based on well-established feminist theory I analyse what the dimensions of quality and character of life can be like for those committed to an environmentally conscious lifestyle, and ultimately gives credence to the notion that there might be deeper psychologica
Histopathology is the procedure used in medicine to optically examine microscope-images of tissue samples (biopsies) in order to study the manifestation of disease. It is used, for example, to diagnose the spread and type of cancer tumors, which have implications on the chosen treatment. Currently this type of analysis is done manually by trained professionals. It is time consuming and the diagnos
The project aims to learn about Chinese young people's choices and attitudes towards cooking and solve their problems in cooking. The solution is presented in the form of a product --- a multifunctional electrothermal cooking appliance. The traditional Chinese saying "Food is god for the people" shows the importance of diet in Chinese life. But today, more and more Chinese young peo
