The wall flameholder is one of the credible alternatives to realize pilot ignition in augmented/ramjet combustors. To overcome the ablation for a long-term operation, two types of jet cooling, external-inhaled air and pressure-driven jet cooling, are proposed for the wall flameholder. In this work, the flow and combustion process in a laboratory scale rig is studied for different cooling schemes a
Background: Pressure–volume (PV) loops provide comprehensive information of cardiac function, but commonly implies an invasive procedure under general anesthesia. A novel technique has made it possible to non-invasively estimate PV loops with cardiac magnetic resonance (CMR) and brachial pressure which would enable good volume estimation of often anatomically complex ventricles without the need of
Ethnomethodology research has systematically investigated discursive practices of categorisation, looking at the various ways by which social actors ascribe both themselves and others to identity categories to accomplish various kinds of social actions. Drawing on a data corpus of oncological visits collected in an Italian hospital, involving both native and non-native patients, the present work a
The length of the menstrual cycle was compared in women with breast cancer, women with benign breast disease, and controls. Older women in general tended to report shorter menstrual cycles (P < 0.05). After correction for the age difference, breast cancer patients still reported a shorter average menstrual cycle length than benign breast disease patients and controls (P < 0.006). Very short cycles
Background: Although low birthweight (LBW) babies represent only 15.5% of global births, it is the leading underlying cause of deaths among newborns in countries where neonatal mortality rates are high. In Uganda, like many other sub-Saharan African countries, the progress of reducing neonatal mortality has been slow and the contribution of low birthweight to neonatal deaths over time is unclear.
From an environmental perspective, a separate collection and recycling system for post-consumer discards could contribute to improved environmental protection as well as economic benefits. This paper investigates the environmental potential of a business model proposed in Sweden in order to improve the utilization of plastic shopping bags. The business model aims to reduce the consumption of plast
Johannes Magnus (1488–1544) was the last Catholic archbishop of Uppsala to hold residence in Sweden. He was also an historian and wrote a major work on Swedish history, the Historia de omnibus Gothorum Sueonumque regibus, which was published posthumously in Rome in 1554. The work eventually became the ideological foundation for Swedish patriotism in the 17th century. The Historia de regibus places
The Brexit Blog Corpus (BBC) is a collection of texts extracted from political blogs, which, in a recent study, was annotated according to a cognitive-functional stance framework by two independent annotators (Annotator A and B) using semantic criteria (Simaki et al. 2017). The goal was to label the stance or stances taken based on the overall meaning of a set of utterances. The annotators were no
Soundcloud is the worlds third largest streaming platform for music. Despite this, the website is riddled with spam comments that disturb user experience. This spam diers much in format and content from the email spam that we are used to seeing, and that most classic spam lters have been developed to detect. On soundcloud, 90% of spam comments are written by users wanting to self-promote their own
Millimeter-wave radar imaging has potential uses in applications such as material analysis and medical in-vivo scanning of tissue. This thesis is about measuring objects using a millimeter wave radar, implement radar imaging algorithms and evaluate the resulting images. The measured objects are plates and rods made of metal and a rod made of acrylic glass (PMMA). The objects are measured using the
In 2004, acute labour shortages were first observed in labour-intensive export-processing sectors in China’s coastal provinces. Paired with rising wages in rural and urban areas, many economists have claimed China has reached its Lewis Turning Point of economic development. This dissertation reviews these claims by context-testing Lewisian theory, and finds little evidence to suggest China has met
Rapporten undersöker begreppet gemensamma servitut. Det övergripande målet är att upplysa om de gemensamma servitutens existens och klargöra under vilka premisser de får och kan bildas. Viktiga frågeställningar blir: vad de är, hur de går att bilda, hur de registreras och hur vanligt förekommande de är. Gemensamma servitut omfattas av samma förvaltningsregler som gemensamhetsanläggningar. En fråga
After reviewing basic concepts and tools in order to quantify entanglement, a theoretical set up is proposed, which is based on the double slit experiment and the Mach-Zehnder interferometer. A particle, which is in a superposition of two paths, can interfere with a qubit on each path before it is scattered by a beam splitter and measured by two separate detectors. After a detailed investigation,
The role for school curators in issues regarding honours related violent is very complex. There are few studies concerning professional experience of management in matters of honour related violent. The purpose of this paper is to examine how the professional school curator's role is described in honour violent cases. Furthermore, focus has been put on highlight the school counselor’s interact
Cross-laminated timber (CLT) is an engineered wood product constructed by combining multiple layers of wood lamellae with adhesives. In the serviceability state, structural timber elements, that are light–weight, are more susceptible to complications regarding the vibration level, than heavier structural elements such as concrete. Contemporary standard practice in the building industry, is to use
This master’s thesis is written for Tetra Pak with the aim to investigate if pitting corrosion inhibition can be detected for Stainless Steel 316L in contact with dairy products in an experimental setup. The aim was also to continue developing a corrosion test method to facilitate for material selection of food pro- cessing equipment in order to reduce the extent of detrimental pitting corrosion.
Lake sediments have lately been explored as a 10Be archive, complementing previous research on ice cores and marine sediments. 10Be is an important proxy as it can be used to study past solar activity, a factor which affects the climate. Where other methods studying solar activity only cover a brief period of history, 10Be has the potential to go further back in time. The concentrations of 10Be st
The report discusses mathematical modeling of thermal components, such as heat exchangers and control valves. A flexible model library for simulation has been developed. The object-oriented and equation-based modeling language Omola is used to describe the components in mathematical terms. The library of models can be used to build models of more complex thermal systems, such as heat exchanger uni
The purpose of this study was to analyse the concept of empowerment and its meaning in the political document "En Förnyad Folkhälsopolitik" from the present Swedish government, containing guidelines and politics in the area of public health. The underlying question was if it could be considered as representative for some kind of general "empowerment approach" since the concept
This essay discusses the border between aggravated assault and attempted murder. This is discussed from the court's perspective and the aim is to examine how the judges decide whether or not the perpetrator has had the necessary intent to be held responsible for attempted murder. The essay includes two parts, one of which is theoretical and one that is practical. The theoretical part begins wi
