In order to obtain information on genes specifically expressed in the ectomycorrhizal symbiosis, 3,555 expressed sequence tags (ESTs) were analyzed from a cDNA library constructed from ectomycorrhiza formed between the basidiomycete Paxillus involutus and birch (Betula pendula). cDNA libraries from saprophytically growing fungus (3,964 ESTs) and from axenic plants (2,532 ESTs) were analyzed in par
Completely homogeneous polyacrylamide-based gels were used for capillary electrochromatography (CEC) of drug enantiomers. Like continuous beds (also called continuous polymer rods, silica rods, monoliths) they do not require frits to support the bed, because it is covalently linked to the capillary wall. Along lifetime is an important feature of the beds. The gel matrices can be prepared in any la
Growth hormone (GH) has insulin-antagonistic effects, and GH secretion is augmented during fasting and hypoglycemia. In the present study, 10 patients aged 21 to 28 years with childhood-onset GH deficiency (GHD) were studied during a 24-hour fast and a hypoglycemic glucose clamp before and after 9 months of GH replacement. During the 24-hour fast, blood glucose, serum insulin, and serum free fatty
The international migration of both skilled and unskilled persons from the global South to the North has reached an alarming proportion.This study investigates the underlying factors that informed the decisions of some African students not to return to their countries of origin after graduation from the Swedish Universities. The participants are former and present students of two Swedish Universit
Title: Climate Change as Experience - A Study on Climate- and Sustainability Communication in Museums Public perception on climate- and sustainability issues is shaped by how they are presented in media and by other communicative actors - like museums. This thesis explores how museum activities can increase public engagement and awareness on climate change and sustainability. The research has bee
The exponential-6 (exp-6) potential is an intermolecular pair potential that is widely used to model fluids at high densities. The path from molecular interaction to equation of state (EOS) for a gas is not straightforward however. Monte Carlo methods and molecular dynamics give accurate results but are too slow for demanding applications like detonation modelling or numerical simulations of react
Den svenska missbruks- och narkotikamodellen bygger på en restriktiv straffrättslig kontroll med ett narkotikafritt samhälle som mål. Trots detta har Sverige idag högst narkotikarelaterad dödlighet i Europa. Portugal använder istället en modell där skademinimering är centralt och förvärv och innehav avsett för eget bruk samt eget bruk är avkriminaliserat. I dagsläget verkar också Norge ta in på et
På grund av digitalisering har samhället träffats med det faktum att många företag erbjuder sina tjänster via internet. Det finns många företag som erbjuder språkundervisande tjänster via internet. Liksom företag verksamma offline, drabbas online verksamma företag av konkurrenssvårigheter. I nuvarande gällande rätt finns det inga exakta beskrivningar på hur konkurrensen på sådana marknader ska regDue to digitalization, society has been hit by the fact that many companies offer their services via the internet. There are many companies that offer language learning services through the internet. Like companies operating offline, online companies are experiencing competitive difficulties. In current applicable law, there are no exact descriptions of how competition in such markets should be re
Krinoidéer, eller sjöliljor, är en klass echinodermer som kan spåras tillbaka till mitten av ordovicium. Dessa växtlika marina invertebrater är antingen bottensittande eller frisimmande och representeras idag av omkring 600 arter, men gruppen var mycket större historiskt med över 6000 kända fossila arter. Patologiska eller missbildade krinoidéer är relativt vanligt förekommande i det fossila arkiv
The aim with this bachelor thesis is to to create an understanding for how people who primary do not define themselves as men experience the community in digital networks that is separatist for them, as well as examine what significance separatism has for people's perceived sense of community. The informants’ experiences of being a part of digital feminist communities that are free from men, a
In workplaces, a lot of knowledge is lost when colleagues change positions. What was once obvious to one person can be incomprehensible to the next. This problem has been encountered by Probation Labs Sweden AB with their biochemical instrument, Labbot. Labbot facilitates researchers in automating their protein analysis. It works like a multi-tool where users can perform one or several tasks in a
Non-exhaust wear emissions from disc brakes affect the air quality in cities throughout the world. These emissions come from the wear of the contact surfaces of both the pads and disc. The tribological and emissions performance of disc brakes strongly depend on the contact surface characteristics of the pads and discs. The surfaces of conventional pads are scorched by heating it to several hundred
The ST14A cell line was previously derived from embryonic day 14 rat striatal primordia by retroviral transduction of the temperature-sensitive SV40 large T antigen. We showed that cell division and expression of nestin persists at 33°C, the permissive temperature, whereas cell division ceases, nestin expression decreases, and MAP2 expression increases at the nonpermissive temperature of 39°C. In
The influence of amino acid sequence and structural context on the backbone dynamics of EF-hand calcium-binding loops was investigated using 15N spin relaxation measurements on the calcium-free state of the calbindin D(9k) mutant (A14D+A15Δ+P20Δ+N21G+P43M), in which the N-terminal pseudo- EF-hand loop, characteristic of S100 proteins, was engineered so as to conform with the C-terminal consensus E
In diabetes mellitus (DM), the kidneys are exposed to increased levels of hyperglycemia-induced oxidative stress. Elevated amounts of reactive oxygen species (ROS) are believed to provoke ultrastructural changes in kidney tissue and can eventually result in DM late complications such as diabetic nephropathy. While it is reported that glucagon-like peptide 1 receptors (GLP-1R) are present in the ki
Soundwalking has its roots as a meditative practice, engaged with ecological concerns. Its origin in R. Murray Schafer's work imbibes it with longing for environments free of industrial sound, and Pauline Oliveros' sound-walking practice seeks the subtle emerging from the silence. Although these progenitors of what we call soundwalking offer us a wonderful palette of listening and walking practice
Agenda 2030 Graduate School monthly newsletter #8 2024-09-09 Ylva van Meeningen Hi! The new semester is in full swing and the university is filled with new students with their very varied initiation and socializing events. One more interesting than the other. At the same time, the first signs of autumn have started to peak up. Even though it does not always feel like it with the heat that has pass
The supramolecular structures resulting from the complexation between the neutral-cationic block copolymer poly(ethylene oxide)- block-poly(2-(trimethylammonium)ethyl methacrylate iodide) (PEO 114- b-PTMAEMAI 95) and the bile salt sodium deoxycholate (NaDC) were investigated by dynamic light scattering, small-angle X-ray scattering, cryogenic transmission electron microscopy and proton NMR techniq
Experiments using the surface force apparatus have found anomalously long-range interactions between charged surfaces in concentrated salt solutions. Ion clustering has been suggested as a possible origin of this behavior. In this work, we demonstrate that if such stable clusters indeed form, they are able to induce remarkably strong free energy barriers under conditions where a corresponding solu
