Stable isotope analysis provides a powerful tool for describing the energetic pathways in a variety of ecosystems. However, isotope ratios of animal tissues can be altered by preservation methods, potentially leading to biased estimates of energy pathways when they are not taken into account. Here, we investigated the direct preservation effects of formalin, ethanol, NaCl, and drying on the delta
To test the hypothesis that dissolved organic nitrogen (DON) is important for sustaining primary production by the microphytobenthos (MPB) in nitrogen-limited conditions, we measured the uptake of (15)N-labelled urea, the amino acids glycine (GLY) and glutamic acid (GLU), and nitrate and ammonium under simulated in situ light and temperature conditions. Microphytobenthic primary production and chl
Background: Animal experimental studies and previous randomized trials suggest an improvement in mortality and neurological function with temperature regulation to hypothermia after cardiac arrest. According to a systematic review, previous trials were small, had a risk of bias, evaluated select populations, and did not treat hyperthermia in the control groups. The optimal target temperature manag
We consider steady symmetric gravity water waves on finite depth with constant vorticity and a monotone surface profile between crests and troughs. The problem is transformed into one concerning the vertical velocity. A representation formula for the stream function in terms of the surface and the vorticity is presented, and we show that the surface can be determined from the vertical velocity.
In this article an operator theoretic interpretation of the generalized Titchmarsh-Weyl coefficient for the Hydrogen atom differential expression is given. As a consequence we obtain a new expansion theorem in terms of singular generalized eigenfunctions.
We consider the effect of signaling rate (baud rate) on the information rate of single carrier linear transmission systems with Gaussian inputs. Several different communication scenarios are investigated: correlated or uncorrelated symbols, a fixed modulation pulse or a modulation pulse varying with the signaling rate and frequency selective or flat channels. For uncorrelated symbols, we show that
The model for permanent deformation in asphalt concrete (AC) layers used in the Mechanistic-Empirical Pavement Design Guide (MEPDG) was evaluated. Two instrumented flexible pavements were subjected to heavy vehicle simulator testing at three constant temperatures. Permanent deformation modelling was carried out using the MEPDG software v1.003 at the highest accuracy level. The nationally calibrate
Pickering emulsions are emulsions that are stabilized by fine particles. They have been the focus of considerable research in the past decade due to their properties such as high stability with respect to coalescence and Ostwald ripening, as well as due to advances in nanotechnology that allows us to create and characterize nano-scale structures in new ways. This work reviews some of the recent wo
A large gravel pit 30 km north of the Pomeranian ice margin has been investigated. Besides gravel, sand, fines and diamicton, several deposits of organic material are present, some of them showing a typical Eemian Pollen- and macroflora. Previous interpretations assume that the sediments below the Eemian peat belong to the Saalian, and those above the peat to the Weichselian. Sorted sediments in t
This report summarizes the classification systems for surface lining materials in Europe and Japan. There is also a part including a discussion on differences, similarities and possible ways to link the two different systems together. In June 1994, an important agreement was made between the member countries in the European Community. The agreement stated that all member countries should have the
The study was conducted through an abductive approach and a qualitative research strategy using a hermeneutic epistemological stance. The data was collected using interviews and respondents selected with a purposive sample technique. With interviews as a data collection technique, we have gathered data from five respondents representing larger listed companies, auditors from the four largest audit
Purpose: The purpose of this thesis is to gain knowledge and visualize significant issues that a future leadership of the Øresund Region should take into consideration in order to promote regional development. Context: In 2000 Copenhagen in Denmark and Malmö in Sweden got connected by the 18km long Øresund Bridge. The bridge’s explicit purpose was not only to physically connect Denmark and Sweden
Populärvetenskaplig sammanfattning I dagens samhälle används diverse katalysatorer i många sammanhang för att påskynda kemiska reaktioner. Allt från produktion av ammoniak till rening av avgaser hjälps av olika katalysatorer. De katalysatorer som vi känner idag har tagits fram genom att testa olika materialkombinationer och utvecklingen har börjat stagnera. Enzymerna i våra kroppar är naturliga kA new instrument for near ambient x-ray photoelectron spectroscopy investigations of surfaces has been installed at beamline I511 of the MAX-II electron storage ring at the MAX IV Laboratory. This high pressure x-ray photoelectron spectroscopy instrument is capable of surface chemistry investigations in near ambient pressures using x-ray photoelectron spectroscopy (XPS), a technique that tradition
The thesis deals with matters relating to neglected diseases and the lack of pharmaceutical R&D for the same diseases. Everybody is entitled to the right to health and subsequently the right to access to medicines, however not everyone has been receiving the benefits of this right. Currently there is an unsatisfying market-driven system, that can be changed by new and innovative approaches, su
With increasing migration to urban areas, Kenya is a country in change with new and challenging problems. Nairobi has a high population growth but a far from equal socio-economic development. As Nairobi continues to grow, so do the slum areas within the city and the slum Kibera has grown to be one of the largest in Africa. Due to the large economic differences within Nairobi I suggest that some pe
This thesis explores a group of young Western-oriented Chinese consumers called xiaozi in Shanghai, comprised mainly by young individuals from an urban lower middle-class background who attempt at adopting a lifestyle and identity marked by a taste for fine arts and foreign culture. The study shows that by means of social distinction through taste and foreign cultural practices the xiaozi youth ca
Under an action research paradigm, this thesis project explores the business potential of an environmental strategy and assesses the formulation of such a strategy implemented by an automotive original equipment manufacturer. Because of the heterogeneous nature of a company’s approach to environmental issues due to inter alia managerial conducts and company culture, this article provides an in-dep
Musculoskeletal disorders (MSDs) affect muscles, joints, tendons and other supporting tissue. They are associated with pain and reduction in the normal range of activity. MSDs are amongst the most common causes of ill health and sickness absence, giving rise to substantial costs for the society. The key aim of this study is to calculate the economic costs of musculoskeletal disorders in Sweden rel
