Spline baseline model flexibility independently affects the accuracy and precision of in vivo proton magnetic resonance spectral fitting in a metabolite-specific manner not visually predicted by fit residuals
In vivo proton magnetic resonance spectroscopy (1H-MRS) data often exhibit baselines or low-amplitude signal variations resulting from residual water, imperfectly suppressed lipids, low-amplitude metabolites not considered for fitting, and other features not represented in a basis set. While multitudinous approaches exist to model these baselines in 1H-MR spectral analysis, many continue to lack sIn vivo proton magnetic resonance spectroscopy (1H-MRS) data often exhibit baselines or low-amplitude signal variations resulting from residual water, imperfectly suppressed lipids, low-amplitude metabolites not considered for fitting, and other features not represented in a basis set.

Regional variation and convergence in living standards in Sweden, 1870–2000
This study investigates regional differences in height in Sweden during the twentieth century using data from universal conscript inspections (for men). We find substantive differences (2-3 cm) in height between the counties. Men in the southern, southeastern and northernmost parts of Sweden were shorter. Men in the Stockholm and Göteborg regions were taller and we find no “urban penalty” in heigh
The rhythm of life and work: Introduction to a special issue in honor of Professor Christer Lundh
Christer Lundh, professor in Economic History at the University of Gothenburg, Sweden, turns 65 in April 2017. This is the age of retirement in the Swedish public’s mind. It has really only been the age for retirement in Sweden since 1967, and since 1994 has been an option rather than a rule (Johannisson and Philp 2015). Given the usual short and slow-changing historical memory of people (includin

Socioeconomic differences in mortality among European settlers in pre-colonial western Africa
Socioeconomic differences in adult mortality are found consistently in high-income countries today. Previous studies have shown that there were, in contrast, no such differences before the twentieth century. The importance of infectious diseases as causes of death and lack of knowledge on how to prevent or cure diseases have been suggested as explanations for this. We investigate the differences i
Multilingual EFL Students’ Intentional Vocabulary Learning : Multimethods Development Research Based on a Word-Focused Task
Intentional vocabulary learning through tasks with an explicit vocabulary focus is essential for L2 learning (e.g., Laufer, 2005; Nation, 2007, 2022; Schmitt & Schmitt, 2020). Yet, research suggests that in EFL classrooms in Sweden, there tends to be a reliance on incidental learning of vocabulary rather than intentional learning (D. Bergström, 2023). Studies(Eriksson, 2023; Warnby, 2023) also
Did the poor pay more? Income-related variations in diet and food quality among urban households in Sweden 1913–1914
We investigate the behaviors used by households to economize on their spending on food using data from a budget survey of urban households in sweden in 1913-1914. Higher-income households bought higher quality varieties of both luxury and staple foods. But changing the composition of the diet was a much more important way to adjust spending on food than changing the quality of the foods bought. Hi

Social Bodies: Family and community influences on height and weight, Southern Sweden 1818–1968
This dissertation consists of an introduction, four research papers and one paper describing the data I collected for the studies and how I conducted the study. I collected information on men from conscript inspection lists and linked this to a sample of men in the Scanian Economic Demographic Database (SEDD) born between 1797 and 1950. The four research papers analyze influences on height and wei

Vägen till vuxenlivet: Det första jobbet och flytten från föräldrahemmet
Idag är det vanligt att ungdomar flyttar hemifrån efter gymnasiet för att studera vidare eller förvärvsarbeta. I samband med det etablerar de ett eget hushåll eller delar hushåll med kamrater eller en sambo. Flytten från barndomshemmet innebär ökat oberoende av föräldrarna och ekonomisk självständighet. Blickar vi bakåt i historien på hur frigörelsen från föräldrarna och inträdet i vuxendomen har
The Politics of Natural Law : Agrarian Reform, Intra-Aristocratic Conflict, and Natural Jurisprudence in Denmark, c. 1750-1800
Syftet med denna avhandling är att undersöka användningen av naturrättsligt språkbruk i de danska agrarreformerna, cirka 1750-1800. Detta görs genom en social kontextualisering som fokuserar på de sprickor som fanns i det danska samhället före och under reformperioden. Jag hävdar att dessa huvudsakligen utgjordes av interna materiella skillnader inom den danska jordägande eliten, inklusive deras oPopular science description The agrarian reforms of the 18th century were some of the most momentous historical events in Danish history. In the span of 30 years, half of all peasants went from living in a state of serfdom to owning and cultivating their own plots of land, free from the onerous ties of manorial dependence that they had toiled under for hundreds of years. In this pioneering dissert
Abdominal organ perfusion and inflammation in experimental sepsis: a magnetic resonance imaging study.
Diffusion-weighted magnetic resonance imaging (DW-MRI) uses water as contrast and enables the study of perfusion in many organs simultaneously in situ. We used DW-MRI in a hypodynamic sepsis model, comparing abdominal organ perfusion with global hemodynamic measurements and inflammation. Sixteen anesthetized piglets were randomized into 3 groups: 2 intervention (sepsis) groups: HighMAP (mean arter
Effect of mechanical ventilation versus spontaneous breathing on abdominal edema and inflammation in ARDS: an experimental porcine model.
Background: Mechanical ventilation (MV), compared to spontaneous breathing (SB), has been found to increase abdominal edema and inflammation in experimental sepsis. Our hypothesis was that in primary acute respiratory distress syndrome (ARDS) MV would enhance inflammation and edema in the abdomen.Methods: Thirteen piglets were randomized into two groups (SB and MV) after the induction of ARDS by l
Duodenum edema due to reduced lymphatic drainage leads to increased inflammation in a porcine endotoxemic model.
BackgroundInterventions, such as mechanical ventilation with high positive end-expiratory pressure (PEEP), increase inflammation in abdominal organs. This effect could be due to reduced venous return and impaired splanchnic perfusion, or intestinal edema by reduced lymphatic drainage. However, it is not clear whether abdominal edema per se leads to increased intestinal inflammation when perfusion
Suction cup on a piston-based chest compression device improves coronary perfusion pressure and cerebral oxygenation during experimental cardiopulmonary resuscitation
Introduction: The presented study aimed to investigate whether a mechanical chest compression piston device with a suction cup assisting chest recoil could impact the hemodynamic status when compared to a bare piston during cardiopulmonary resuscitation.Methods: 16 piglets were anesthetized and randomized into 2 groups. After 3 minutes of induced ventricular fibrillation, a LUCAS 3 device was used
