Insights into oceanographic environmental conditions such as paleoproductivity, deep-water temperatures, salinity, ice volumes, and nutrient cycling have all been obtained from geochemical analyses of biomineralized carbonate of marine organisms. However, we cannot fully understand geochemical proxy incorporation and the fidelity of such in species until we better understand fundamental aspects of
This work describes the use of focused, high-intensity light from a Ti: sapphire laser that generates femtosecond pulses to irradiate mixture of CeO2 and Tb4O7 under ambient conditions. The prepared samples were investigated by means of X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS) and scanning electron microscope (SEM). XRD and XPS measurement results demonstrated that solid sol
ZnWO4, ZnWO4 : Fe and ZnWO4 : Mo crystals were investigated by the methods of time-resolved spectroscopy in the temperature range of 4.2-300 K. It is shown that the Mo and Fe impurities significantly reduce the light yield of ZnWO4. The main 2.5 eV emission of ZnWO4 and the 1.77 eV emission band of ZnWO4 : Mo are shown to originate from the triplet excited state of the WO6 and MoO6 complex, respec
Results from a Monte Carlo investigation are presented for the application of the dual photopeak window (DPW) scatter correction method to phantom geometries of varying shapes, sizes, and densities as well as to several collimators. A Monte Carlo program was used to simulate a Tc-99m point source at locations of 0.5 cm from the phantom surface, at the center, 0.5 cm from the bottom, and 4/5 the di
The aim of this study was to examine how social workers working with the Staircase Model and Housing First can help long-term homeless people with a long history of alcohol and/or drug abuse, their view of the models and how they describe and use their discretion. I used a qualitative method and data was gathered by semi-structured interviews. I interviewed five social workers in four different mu
Understanding the gut-brain-microbiota axis can help us provide a new tool to manage conditions such as Alzheimer’s. However, a major challenge is selectively amplifying the bacterial DNA which is present at a much lower level than the host DNA. In this thesis, we aim to develop a methodology to extract, purify and quantify the bacterial DNA in the brain tissue of mice. The methodology that can be
Sex-limited polymorphism is an interesting evolutionary phenomenon, which is widespread across organisms. Studying ultimate mechanisms that result in the evolution of sex-limited polymorphism can provide a window into how natural and/or sexual selection can result in the evolution of complex phenotypes. Here, I use butterflies from the tribe Polyommatini to study the evolutionary mode and tempo of
Introduction: Functional magnetic resonance imaging (MRI) is a non-invasive method which uses a combination of a strong magnetic field and radio frequency pulses to image magnetic difference between oxygenated and deoxygenated blood in the human brain. This contrast differences can be used to identify areas in the brain when subjects performing an active task in the MRI scanner. It is also possibl
Det kan sägas att extraordinära rättsmedel och dess resningsregler i dagens rättegångsbalk 58 kap. härstammar från konungens förmånsrätt att bryta domar under 1100-talets högmedeltid. Begreppet rättskraft och behovet av att angripa lagakraftvunna domar slog inte igenom förrän i slutet av 1600-talet. Dåvarande regler tillämpades formellt inte vid brottmål, men kom ändå att i praktiken att göra det.One can say that the extraordinary remedies and their rules regarding the relief for a substantive defect in today’s Code of Civil Procedure (Section 58) originate in the king’s preferential right to annulate court decisions during the late middle ages in the 1100s. The concept of legal force and the need to impugn court decisions that have taken legal effect was not noticed before the end of the
Background: Since 1994 the need for joint sexual and reproductive health (SRH) responsibility between men and women to achieve gender equality and reduce health inequalities has received more attention. The focus has been on young people as they transition into adulthood and are vulnerable to the negative consequences of early pregnancy and childbirth, STIs and early parenthood. Traditionally, con
Anthropogenic land-use covers a constantly increasing fraction of the terrestrial surface area. By employing a dynamic global vegetation model, human-induced changes in the terrestrial water balance as compared to an undisturbed scenario were simulated. The results suggest that humanity is a main driver of change in the terrestrial water balance in general and green water in particular. Most strik
Despite the increasing level and number of techniques deployed to generate more robust, better-producing microbial cell factories for production of chemicals, the number of products that reach commercial feasibility is still very low. Many hurdles come along the way as it has been observed that strains designed in the laboratory do not perform as expected in industrial-scale bioreactors. For insta
Background: Misuse of substances is a major contributor to disability and mortality worldwide. The use of tobacco, alcohol, and illegal drugs in adolescence and young adulthood are well-known risk factors for subsequent substance-related harms. A better understanding of adolescent and young adult substance use behaviors and their correlates might help develop new prevention programs. This thesis a
We report on measurements of the light absorption efficiency of InSb nanowires. The absorbed 70 fs light pulse generates carriers, which equilibrate with the lattice via electron-phonon coupling. The increase in lattice temperature is manifested as a strain that can be measured with X-ray diffraction. The diffracted X-ray signal from the excited sample was measured using a streak camera. The amoun
An armchair is a necessity all of us have at home or in our work place. Sitting is often more comfortable than standing, but sitting is not the best option when it comes to our health. As we grow older, our bodies weaken and standing in a longer period gets more difficult. Here is where I started this project. A nursing home for the elderly with dementia called the Fullriggaren contacted the scho
It’s not unusual for young people these days to take and edit a selfie. With the rise of consumerist culture and the popularity of mobile Internet, nowadays selfie applications, including beauty cameras and photo-beautification applications, have become the most well-accepted products/brands among Chinese women, who have grown accustomed to showing only one exquisitely edited face in digital photo
This report has been conducted to examine the advantages and disadvantages of using an open system for experiments in the cone calorimeter with a vitiated air enclosure at low oxygen levels. Eight different experimental set-ups were conducted in which two were designed according to ISO 5660, i.e. the cone calorimeter in its standard configuration. In the other experimental set-ups, a chamber which
How young women with depression experience attitudes from other people - four anecdotes interpreted from a lifeworld perspective The aim of this master thesis was to, through a lifeworld perspective, understand how young women with some form of depression, experience other people’s negative attitudes towards depression. Using a hermeneutic phenomenological method, as described by Max van Manen, f
Domestic violence is an increasingly common problem in our society. In 2012 there were 28,400 cases reported of assault against women over 18 and almost half of these women reported having been abused by a loved one. In support of these women there is sheltered accommodation around the country, about half of Sweden's municipalities have a shelter for women and these are conducted both municipa
The aim of this study was to research social secretaries' views on and experiences working with social and economic violence in honor-based context. The method chosen for this study was qualitative semi-structured interviews with seven different social secretaries, all active in various units and with different experiences. The study concludes how economic and social violence can take form in
