The aim of this thesis is to investigate and evaluate the use of escape filters during the construction phase of tunnels and mines. To achieve this aim three main research methods were used. Firstly, a literature review was produced to evaluate the current research about escape filters and fire safety during the construction phase of tunnels and mines. Secondly, interviews were conducted to find r

Finansiell leasing är tillsammans med traditionella banklån och avbetalningsköp den vanligaste formen av extern finansiering för små- och medelstora företag i Sverige. Det är dessutom en finansieringsform som förväntas öka kraftigt i popularitet till följd av de kreditgivningsreformer som många banker tvingats genomföra efter finanskrisen 2009 samt den pågående euro- krisen. Trots detta saknas til

There is a lack of research on how young adults experienced having a parent with a dementia-related illness, particularly regarding the support they received. This knowledge gap risked leaving young relatives without adequate help, as existing support systems were often designed for older relatives. Therefore, it was essential to explore their needs and experiences. The aim of this study was to ex

Feminist foreign policy initiatives have since they first appeared weathered criticism when put in relation to an active weapons export often to non-democratic states violating women’s rights. This paper then examines the Swedish case by using argumentation analysis as method to test the moral commitments of Sweden’s foreign policy initiative against recent arms deals. It was made to explore the p

The purpose of the study was to explore wheter and what possible risks that were discussed by student health prior to the introduction of distance learning during Covid-19. Also the possible consequences that the distance learning has contributed to from the school counselors perspective. The study had a qualitative approach which included six semi-structured interviews with school counselors. The

This thesis analyses the question of the right to compensation for victims of racial discrimination. The purpose is first of all to determine whether or not victims of racial discrimination have a right to compensation under international human rights law and to establish the content and limits of such a right. In order to achieve this purpose four specific questions are examined, namely: 1. Is th

Objectives: Does thrombin activation seen in patients with abdominal aortic aneurysms (AAA) relate to the thrombus surface area or volume within the aneurysm? Patients and methods: A total of 130 patients with AAA were analyzed regarding levels of the complex between activated protein C-protein C inhibitor (APC-PCI) and AAA morphology. Analysis of APC-PCI complex was made using a sandwich immunofl

The aim of this thesis is to develop two idealtypes of politics to help serve as instruments in understanding and analysing the view on politics held by top civil servants in the municipality of Lund Sweden. The two ideal types developed here are symbolic sense making politics and rational instrumental politics. These two ideal types were applied to material from a qualitative survey to help bring

The purpose of this paper was to increase understanding of how foreign professionals within the diplomatic sector, working with foreign relations to Japan, feel, perceive and relate to Japanese nationalism. The concept of banal nationalism and semiology was used as a theoretical base for the study, as well as theories of Japanese cultural or racial uniqueness (Nihonjinron). A phenomenological meth

Abstract Ky words: crack spread, mde oil, heating oil, mz,tLtivariate GARCH This thesis was performed using daily one-month future prices from 1996 until 2004; on the two assets that make up the heating oil spread i.e. crude oil and heating oil, traded on the New York mercantile exchange (NYMEX). The goal of the study was to, by designing future strategies and predicting the variance and volatilit

Åldersbestämning med 14C-metoden kräver kalibrering med hjälp av en oberoende dateringsteknik. En idealisk metod som idag används för kalibreringen är dendrokronologi, eftersom trädens årsringar utgör ett nästan perfekt arkiv av 14C-halten i atmosfären och eftersom dendrodatering är en mycket exakt metod. Bakgrunden till detta arbete är ett forskningsprojekt vid Lunds universitet, där man i trädriRadiocarbon dating requires calibration by an independent dating technique. An ideal method used to calibrate radiocarbon results is dendrochronology, because tree-rings are almost perfect archives of the atmospheric radiocarbon level and dendrodating can be very accurate. However, an age offset between the calibrated 14C and dendrochronologically-dated ages has been observed for certain pine-tree

During the past year my academic career has been rather different than the years before. In my undergraduate studies of economics & business economics, a mixture of different disciplines like microeconomics, marketing, organizational theory and finance, all I needed to worry about was to make sure I would pass the courses. I found that a rather unsatisfying way of studying; grades didn’t motiv

The present thesis studies the monitoring of the 2012 Russian presidential elections and explores theoretical and empirical questions of the influence of domestic and international actors on the election process. The study of the election observation is one of the topics of the very large field of study on democratization and, more specifically, democracy-promotion and assistance; therefore in my

The aim of the study was to examine how Registered Nurses perceive ethical problems within healthcare and enlighten the ongoing discussions concerning them. Five Registered Nurses at a surgical ward were interviewed in order to perform an empirical study. A literature review was also done where five articles were analysed. The findings show that the patients autonomy, personal sphere and rights, s

Bit-error rate measurements for ON-OFF keying modulation at multigigabit per second rates over a V-band wireless link are presented. Serial data-rates from 2.5 to 20 Gb/s were studied for a 231-1 bit random sequence. Error-free data transfer over a 0.3-m link was achieved at up to 10 Gb/s. Acceptable bit-error rates, <10-5 and 10-3, were measured at up to 1.5 m for 10- and 15-Gb/s data-rate, respe

In this paper we report on a facile, cost effective and environmental friendly green synthesis method of gold and silver nanoparticles (NPs) by using quercetin as reducing agent. The obtained NPs were characterized by transmission electron microscopy (TEM), energy dispersive spectroscopy (EDS), dynamic light scattering (DLS) and UV-Vis spectroscopy and parameters such as pH, ionic strength and tem

Spending the winter in northern climes with short days and cold ambient temperatures (Ta) can be energetically challenging for small birds that have high metabolic and heat loss rates. Hence, maintaining body temperature (Tb) in Ta below thermoneutrality can be energetically costly for a small bird. We still know little about how increased heat production below thermoneutrality affects the level aSpending the winter in northern climes with short days and cold ambient temperatures (Ta) can be energetically challenging for small birds that have high metabolic and heat loss rates.

The lamellar-to-sponge phase transition of fluorescently labelled large unilamellar vesicles (LUVs) of the non-ionic surfactant triethylene glycol mono n-decyl ether (C 10 E 3 ) was investigated in situ by confocal laser scanning microscopy (CLSM). Stable dispersions of micrometer-sized C 10 E 3 LUVs were prepared at 20 °C and quickly heated at different temperatures close to the lamellar-to-
