Stoichiometric and very rich flames of methane have been investigated using nonintrusive laser diagnostics. Absolute concentration profiles of HCO were measured by intracavity laser absorption spectroscopy, and temperature profiles were obtained with laser-induced fluorescence of OH. Premixed CH4 + O-2 + N-2 flames were stabilized at a pressure of 30 +/- 0.3 Torr. These new experimental data were
In this thesis I explore the subject on how burial was used by Viking Age population of South-western Scania to express their social identity. As opposed to most earlier research concerning Viking Age burials I utilise regional, mourner-centred and practice-based approach. I am following observations conducted for burials in Denmark by J. Ulriksen (2011), focused on traces of deposition of burned
Charred seed conglomerates of Linum usitatissimum (flax) and Camelina sativa (gold of pleasure) were found at UppAyenkra 2:25, a Roman Iron Age site in SkAyenne, southern Sweden. The conglomerates showed no mixing with each other, as they were almost pure flax and gold of pleasure respectively. Together with other archaeobotanical data from the site, they provide new evidence on the use, processin
The aim of the present study was to examine the influence of pregnancy on deterioration of retinopathy in patients with Type 1 diabetes mellitus. Sixty-five pregnant Type 1 diabetic women attending the University Hospital in Lund were studied retrospectively. The degree of retinopathy, and levels of HbA1c and blood pressure 12 months before, during, and 6 months after pregnancy were compared of th
Visits to nest holes by birds other than their owners is a familiar phenomenon for students of breeding biology. In this study, we evaluate that behavior using a transponder reading system. Eighty-five males and females were Fitted with transponders at the end of the incubation period or just after hatching. Nest boxes were fitted with transponder readers from just after hatching until all nestlin
Maternal diet during pregnancy has been proposed to increase the risk of autoimmune diseases.
To determine the effects of dipeptidyl peptidase-4 (DPP-4) inhibition on glucagon dynamics in patients with insulin-treated type 2 diabetes (T2D).
Written daily reflections during clinical practice on birthing units have been used during several years in midwifery education at Lund University, Sweden. However, the usefulness of these reflections for evaluation of progression in learning and professional development of students has to date not been evaluated. In order to analyse written reflections, two taxonomies developed by Bloom and Pette
Objective: Microbial manipulations in early life can affect gut development and inflammatory status of the neonate. The maternal diet during pregnancy and lactation also influences the health of the offspring, but the impact of maternal high-fat (HF) feeding along with modulations of the gut microbiota on body weight, fat deposition and gut function in the offspring has been poorly studied. Method
A sediment sequence from a small forest lake in southwestern Sweden was investigated to explore the effects of forestry and land-use on catchment erosion and delivery of organic and minerogenic matter to the lake. Catchment-scale vegetation changes during the last 1,100 years were reconstructed quantitatively at 50-year resolution using pollen analysis and the Landscape reconstruction algorithm (L
This work aims to investigate the breakup dynamics of the low-density gas and liquid interface during bubble formation in a microchannel flow-focusing device. A high-contrast interface tracking method is developed. After the neck motion analysis in radial and axial directions, the time domain criterion between the liquid squeezing stage and the free pinch-off stage is proved to be two orders of ma
Aim: Studies examining the long-term effects of neonatal music interventions on the cognition of children born preterm are scarce. We investigated whether a parental singing intervention before term age improves cognitive and language skills in preterm-born children. Methods: In this longitudinal, two-country Singing Kangaroo, randomised controlled trial, 74 preterm infants were allocated to a sin
This study investigated the clinical interpretation of three electromyographic (EMG) normalisation techniques to detect neuromuscular alterations in patients diagnosed with anterior cruciate ligament knee injury during treadmill walking. The EMG signal was normalised using the mean value during the gait cycles (MEA), the maximum value during the gait cycles (MAX), and a maximum voluntary isometric
A new concept has been developed for characterizing the real-time evolution of the three-dimensional pore and lamella microstructure of bread during baking using synchrotron X-ray microtomography (SRµCT). A commercial, combined microwave-convective oven was modified and installed at the TOMCAT synchrotron tomography beamline at the Swiss Light Source (SLS), to capture the 3D dough-to-bread structu
Public health measures introduced in early 2020 to curb the spread of Covid-19 played a critical role in mitigating the worst effects of the pandemic. This column highlights how to understand the effectiveness of these policies in MENA, and the importance of evaluating the relationship between risk perception and compliance. People’s risk perception and attitudes towards the disease varied over ti
