The mechanomyogram (MMG) is a mechanical oscillations observable on the surface of the skin as a muscle contracts. Measurement of the MMG utilizing contact sensors with a weight greater than 6 g has proved to interfere with the measurement. Use of optical displacement sensors without direct contact to the skin would remove this deficiency. A Michelson interferometer, an intensity shift set-up and
Sweden is striving to fulfill Vision Zero, a road traffic safety project that aims to prevent people from getting killed or seriously injured in traffic. To further improve safety and accessibility of the existing roads, widening of roads can be performed. The purpose of this thesis is to identify and summarize different variants of construction for road widening, using the existing data and exper
BACKGROUND: Vacuum-assisted abdominal closure (VAC) is being increasingly used as an adjunctive procedure in the surgical treatment of secondary peritonitis. This study compared postoperative mortality and complication rates between VAC and primary abdominal closure (PAC).METHOD: This retrospective chart review included all patients diagnosed with secondary peritonitis who underwent laparotomy bet
This thesis is a material science research collaboration between the Division ofProduction and Materials Engineering at Lund Faculty of Engineering and theComputer-Aided Engineerings group at BorgWarner, Landskrona. The objectiveof the thesis is to explore the convertion of nanoindentation load-depth curves intotensile stress-strain curves, and to provide BorgWarner Landskrona with nanoin-dentatio
The concept of marriage as a union of a man and a woman was fundamentally challenged by the introduction of registered partnership in Denmark in 1989. Odd Couples is the first comprehensive history of registered partnership and gay marriage in Scandinavia. It traces the origins of laws which initially were extremely controversial—inside and outside the gay community—but have now gained broad popul
The effect of modification of osmotic medium composition with salts on the texture changes and process kinetics was evaluated in the present study. Inner and outer apple cortex parenchyma (Kim var.) was subjected to osmotic processing at 20.40 and 60 degrees C. The four osmotic media used were of identical osmotic pressure but slightly different compositions. The solution 1, Si, was a 50% w/w sucr
Aim: To establish the current level of knowledge of the effect of drinking cessation on the risk of developing oesophageal cancer. Method: A meta-analysis was conducted based on relevant studies identified through a systematic literature review. A Generalised Least Squares model for trend estimation of summarised dose-response data were utilised in order to estimate the effect of years since drink
Exposure to arsenic (As), cadmium (Cd) and lead (Pb) may generate oxidative stress, which can be assessed by 8-oxo-7,8-dihydro-2'-deoxyguanosine (8-oxodG) in urine, a sensitive marker of oxidatively damaged DNA. We have evaluated oxidative stress induced by mixed chronic exposure to As, Cd, Pb, as well as the influence of As metabolism and nutritional status, i.e. ferritin (Ft), selenium (Se), zin
Background: A central theme in media psychology is how certain contemporary and dominant views may tend to perpetuate themselves by presenting a recurring picture we humans use to form our knowledge about the world. The present study is based on 1.5 million words from articles published online in the Swedish daily newspapers in 2010. We investigated which words were most (un-)common in articles co
Aims In adults with coarctation of the aorta (CoA), hypertension (HTN) is a common long-term complication. We investigated the prevalence of HTN and analyzed factors associated with HTN. Methods and results In the national register for congenital heart disease, 653 adults with repaired CoA were identified (mean age 36.9 ± 14.4 years); 344 (52.7%) of them had HTN, defined as either an existing diag
IntroductionLow serum selenium and altered tumour RNA expression of certain selenoproteins are associated with a poor breast cancer prognosis. Selenoprotein expression stringently depends on selenium availability, hence circulating selenium may interact with tumour selenoprotein expression. However, there is no matched analysis to date.MethodsThis study included 1453 patients with newly diagnosed
Background: The registry-based randomized VALIDATE-SWEDEHEART trial (NCT02311231) compared bivalirudin vs. heparin in patients undergoing percutaneous coronary intervention (PCI) for myocardial infarction (MI). It showed no difference in the composite primary endpoint of death, MI, or major bleeding at 180 days. Here, we report outcomes at two years. Methods: Analysis of primary and secondary endp
Purpose: Genetic diversities in different countries affect the performance of HIV test kits. Therefore, WHO recommends evaluation of every HIV test kit in countries' context before its use. Therefore, this study aimed to evaluate the performance of Genscreen ULTRA HIV Ag-Ab and Bioelisa.Materials and methods: The study had used 400 characterized plasma samples obtained from CDC Atlanta bio-bank de
We determined the effects of plasmapheresis on cytotoxic antibodies to islet cells in 10 children (aged 11-16 yr) with newly diagnosed insulin-dependent diabetes mellitus (IDDM), as well as the plasma levels of antibodies over the next 30 mo and their relation to serum C-peptide concentrations. Complement-dependent, antibody-mediated cytotoxicity (C'AMC) in plasma was measured in a 51Cr release as
Bioassay experiments were performed two times (with 2 years in between) in order to investigate if nitrogen (N, ammonium), phosphorus (P, phosphate) and carbon (C, glucose) additions would stimulate the growth of bacteria and phytoplankton differently in three different tropical aquatic environments. The water and their indigenous microbial communities were taken from a freshwater coastal lake (Ca
Background and purpose Bone morphogenic proteins (BMPs) can be used in non-unions to replace autograft. BMPs induce osteoblasts and (less well known) also osteoclasts, which can in turn be controlled by a bisphosphonate. In the present study, our aim was to improve the biological effect of autologous bone graft by adding an anabolic BMP, with or without bisphosphonates, in an open-fracture model p
The most important parameter for estimates of the anthropogenic induced climate change is the radiative forcing. In a comparison of the earth’s radiative budget in the year 2011 relative to 1750, the intergovernmental panel on climate change concludes that the largest uncertainty in the total radiative forcing derives from aerosol particles and their ability to modify cloud properties as cloud con
Internet dating has with the advent of dating apps gone mobile. Furthermore, social media apps and virtual contact are playing an increasing vital role in courtship and flirtation processes while also easing the aches of distance relationships. Online behaviors have consequences on mental health, the purpose of this bachelor thesis is to examine what the dominant dating apps and social media platf
Application of Pulsed Electric Field (PEF) treatment on five fresh commodities was analysed for the changes in the metabolic and physiological effects on their shelf life. Treatment parameters were optimised in order to achieve uniform electroporation on the samples, which was analysed by Propidium Iodide staining for the leaf samples. The viability of electroporation of greenhouse (GH) rocket, co
