Forty patients with a mean age of 45 (range 22-65) years were operated on between 1982 and 1985 for gastro-oesophageal reflux disease with a short floppy 360 degree fundoplication. The results of the operation were determined by endoscopy, oesophageal manometry, ambulatory 24-h pH recording and symptom evaluation 6 months and 5 years after operation. These results were compared with findings in he
The kinetic isotope effects in the reactions of CHCl3, CDCl 3, and 13CHCl3 with Cl, OH, and OD radicals have been determined in relative rate experiments at 298 ± 1 K and atmospheric pressure monitored by long path FTIR spectroscopy. The spectra were analyzed using a nonlinear least-squares spectral fitting procedure including line data from the HITRAN database and measured infrared spectra as ref
The impact of commuting on health depends, in part, on the mode of travel. A sizeable body of literature addresses associations between mode choice and health status, but little is known about how a person's health affects commuting mode choice. Stress, exhaustion and obesity are threats to public health that increase in modern societies. Understanding how these concerns impact mode choice is impo
NOx pollution from Diesel engines causes over 10 000 premature deaths annually and the trend is increasing. In order to decrease this growing global problem, exhaust after-treatment systems for Diesel engines have to be improved. The most common SCR systems in the market place inject an aqueous Urea solution, DEF that evaporates prior the catalytic surface of the SCR-catalyst. Due to a catalytic r
Cancer research has transformed our view on cellular mechanisms for oxygen sensing. It has been documented that these mechanisms are important for maintaining animal tissues and life in environments where oxygen (O2) concentrations fluctuate. In adult animals, oxygen sensing is governed by the Hypoxia Inducible Factors (HIFs) that are stabilized at low oxygen concentrations (hypoxia). However, the
This thesis challenges the prevailing firm-consumer/customer-centric and dyadic perspective that prevails within the brand equity literature, which is based on a linear, straightforward stimulus-response approach to the creation of brand value. Leaning on the literature on interorganisational relationships, stakeholder theory, market emergence/market driving, and firm internationalisation, which s
Young birds in cold environments face a range of age-specific thermal challenges. Studying the thermal biology of young birds throughout ontogeny may further our understanding of how such challenges are met. We investigated how age and environmental parameters influenced surface temperature gradients across various body regions of wandering albatross (Diomedea exulans) chicks on Bird Island, South
Alternative reproductive tactics (ARTs) have provided valuable insights into how sexual selection and life history trade-offs can lead to variation within a sex. However, the possibility that tactics may constrain evolution through intralocus tactical conflict (IATC) is rarely considered. In addition, when IATC has been considered, the focus has often been on the genetic correlations between the A
Global climate change is driving species' distributions towards the poles and mountain tops during both non-breeding and breeding seasons, leading to changes in the composition of natural communities. However, the degree of season differences in climate-driven community shifts has not been thoroughly investigated at large spatial scales. We compared the rates of change in the community composition
OBJECTIVE: The aim of the present study was to examine the effects of incomplete surgery and adjuvant chemotherapy on the prognosis of patients with intraoperative rupture of capsulated stage I epithelial ovarian cancer (OvCa). METHODS: A regional retrospective study was conducted between 1986 and 2019. Among 4,730 patients with malignant ovarian tumors, 534 women with International Federation of
PurposeIncumbent retail organisations need to develop new capabilities to adapt with the increasingly competitive retail landscape. Despite the growing relevance of innovation in retail practice, the strategic management of innovation in retailing is still vastly under-researched. This explorative study thus aims to investigate how incumbent retail firms can organise for innovation from an organis
BACKGROUND: Hereditary angioedema (HAE) is caused by low levels of or defects in C1 inhibitor. Although disease activity may be modified by prophylaxis, emergency treatment, treatment for comorbidities, and oral contraceptives, the extent of their use is unclear. OBJECTIVE: To investigate trends in the use of disease-specific and interfering drugs in patients with HAE compared with the general pop
The invention of the laser in 1960 gave us the ruby laser, which generally produced chaotic pulses of light. Six years later, in 1966, a concept called passive mode-locking applied to neodymium-glass lasers produced reasonably well-behaving picosecond pulses. This triggered an intense activity, with respect to developing improved laser pulse sources, measurement techniques, and application to chem
Background: The Nordic Nutrition Recommendations (NNR) are developed to promote public health and to prevent food-related diseases such as obesity and cardiovascular diseases. Objective: To investigate the nutrient intake and adherence to the NNR in a Swedish cohort with abdominal obesity. Design: Dietary intake data were collected using 3-day food diaries and anthropometry and clinical chemistry
The objective of this thesis is to investigate the synthesis of well-defined polymer nanohybrid materials bearing desirable functionality via surface-initiated atom transfer radical polymerization (SI-ATRP) for potential bioapplications.SI-ATRP is an excellent controlled radical polymerization (CRP) method for the synthesis of polymer nanohybrid by growing polymer brushes (chains) from an interfac
Most microalgal species are geographically widespread, but little is known about how they are dispersed. One potential mechanism for long-distance dispersal is through birds, which may transport cells internally (endozoochory) and deposit them during, or in-between, their migratory stopovers. We hypothesize that dinoflagellates, in particular resting stages, can tolerate bird digestion; that bird
Lärares praktiska yrkeskunskaper bjuder motstånd mot förspråkligande. Detta problem föreligger inte minst i lärarutbildningen, där det i verksamhetsförlagda delar kan råda både osäkerhet och skilda uppfattningar om vad studenterna behöver göra eller prestera för att uppnå de mål som (bokstavligen) föreskrivits dem. Syftet med avhandlingen har varit att beskriva och förstå villkor och förutsättningTeachers' practical professional skills offer resistance to advocacy. This problem exists not least in teacher education, where in work-based parts there can be both uncertainty and different perceptions of what the students need to do or perform in order to achieve the goals that are (literally) prescribed for them. The purpose of the dissertation has been to describe and understand conditions an
An improvement in photosynthetic rate promotes the growth of crop plants. The sink-regulation of photosynthesis is crucial in optimizing nitrogen fixation and integrating it with carbon balance. Studies on these processes are essential in understanding growth inhibition in plants with ammonium ((Formula presented.)) syndrome. Hence, we sought to investigate the effects of using nitrogen sources wi
The rapid pace of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2; COVID-19) pandemic presents challenges to the real-time collection of population-scale data to inform near-term public health needs as well as future investigations. We established the COronavirus Pandemic Epidemiology (COPE) consortium to address this unprecedented crisis on behalf of the epidemiology research comm
In 2019 October Betelgeuse began a decline in V-band brightness that went beyond the minimum expected from its quasi-periodic ∼420 day cycle, becoming the faintest in recorded photometric history. Observations obtained in 2019 December with Very Large Telescope/SPHERE have shown that the southern half of the star has become markedly fainter than in 2019 January, indicating that a major change has
