Lactam analogues of galiellalactone

A synthetic route to lactam analogues of the fungal STAT3 inhibitor galiellalactone is presented. The synthesis involves a one-pot tosylamide amide coupling/intramolecular Michael addition and an introduction of an alpha,beta-unsaturation, regioselectively directed by the tosyl functionality. An iodolactonization of the octahydroindolizine 9 and a re-opening of the lactone were employed for introd

An investigation of Cu(II) and Ni(II)-catalysed hydrolysis of (di)imines

The reactions of six diimine ligands with Cu(II) and Ni(II) halide salts have been investigated. The diimine ligands were Ph2C=N(CH2)(n)NC=Ph-2 (n = 2 (Bz(2)en, 1a), 3 (Bz(2)pn, 1b), 4 (Bz2bn, 1c)), N, N'-bis-(2-tert-butylthio- 1-ylmethylenebenzene)-2,2'diamino-biphenyl (2), N,N'-bis-(2-chloro-1-ylmethylenebenzene)-1,3diaminobenzene (3) and N,N'-bis-(2-chloro-1-ylmethylenebenzene)-1,2-ethanediamin

Atmospheric synthesis of superhydrophobic TiO2 nanoparticle deposits in a single step using Liquid Flame Spray

Titanium dioxide nanoparticles are synthesised in aerosol phase using the Liquid Flame Spray method. The particles are deposited in-situ on paperboard, glass and metal surfaces. According to literature, titanium dioxide is supposed to be hydrophilic. However, hydrophobic behaviour is observed on paperboard substrates but not on metal or glass substrates. Here, the water contact angle behaviour of

Chyliza leguminicola Melander, 1920 (Diptera: Psilidae) new to the Palaearctic fauna.

The Nearctic species Chyliza leguminicola Melander, 1920 has been found breeding in Denmark. It is reported here for the first time in the Palaearctic region. The first known Danish record is from 1991, and the species is well established at least in the eastern part of Jutland. Data on the distribution as currently known is presented. It is possible that C. leguminicola is actually established bu

The PREDICTS database: a global database of how local terrestrial biodiversity responds to human impacts.

Biodiversity continues to decline in the face of increasing anthropogenic pressures such as habitat destruction, exploitation, pollution and introduction of alien species. Existing global databases of species' threat status or population time series are dominated by charismatic species. The collation of datasets with broad taxonomic and biogeographic extents, and that support computation of a rang

Mating Preferences of the Gynogenetic Amazon Molly Differ Between Populations Sympatric with Different Host Species

Gynogenetic species rely on sperm from heterospecifics for reproduction but do not receive genetic benefits from mating because none of the paternal genome is incorporated into offspring. The gynogenetic Amazon molly (Poecilia formosa) is a species of hybrid origins that are sympatric with one of the two parent species that provide sperm for reproduction, P. latipinna or P. mexicana. Amazons shoul

This dissertation deals with the morphological development in written L2 French by Swedish learners. The thesis presents a detailed analysis of number marking and agreement in NPs and VPs, focusing mainly on the production of the morphemes –s (in NP) and the third person plural –nt (in VP). These agreements are particularly interesting in French where number morphology is often silent in the oral

Differences in abundance, species richness, and body size of ground beetles (Coleoptera: Carabidae) between beech (Fagus sylvatica L.) forests on Podzol and Cambisol

Ten forest sites with a tree layer of almost pure beech in southern-central Scania, south Sweden, were studied. They were all located in the interior of large forest stands. Five of the stands were developed on mor Podzols with scanty or almost no ground layer vegetation. The other five sites were located on mull Cambisols with a rich ground layer of many vascular plant species and a shrub layer o

Copy Number Variation Analysis in Familial BRCA1/2-Negative Finnish Breast and Ovarian Cancer

Background: Inherited factors predisposing individuals to breast and ovarian cancer are largely unidentified in a majority of families with hereditary breast and ovarian cancer (HBOC). We aimed to identify germline copy number variations (CNVs) contributing to HBOC susceptibility in the Finnish population. Methods: A cohort of 84 HBOC individuals (negative for BRCA1/2-founder mutations and pre-scr

Laser-Produced Plasmas for Particle Acceleration

This thesis describes experimental studies that aim to stabilise and optimise laser-based particle accelerators. The technique is called laser wakefield acceleration, where electric fields of the order of 102 GV/m accelerate electrons to high energies (⇠102 MeV) over mm-distances in laser-produced plasmas. Among the prerequisites for this acceleration technique to produce electron beams are laser

Alcohol Use and Stress in University Freshmen - A Comparative Intervention Study of Two Universities

Starting university is associated with major academic, personal and social opportunities. For many people, university entrance is also associated with increased stress and alcohol consumption. At the start of the autumn term 2002, all students entering educational programmes at two comparable middle-sized Swedish universities were invited to participate in a comparative intervention study. This in

On Aniridia in Sweden and Norway

Introduction Aniridia (iris more or less missing), is a congenital, dominant, inherited, serious and sight-threatening disease, most often appearing as an isolated eye disorder. It is caused by mutations in the PAX6 gene, the master gene of the development of the eye. Typically, Aniridia causes severe visual impairment. In addition to glare caused by the iris defect, underdevelopment of the macula

Eating out of home: energy, macro- and micronutrient intakes in 10 European countries. The European Prospective Investigation into Cancer and Nutrition

Objectives: To assess the contribution of out-of-home (OH) energy and nutrient intake to total dietary intake, and to compare out-versus in-home nutrient patterns among 27 centres in 10 countries participating in the European Prospective Investigation into Cancer and Nutrition (EPIC) study. Methods: Between 1995 and 2000, 36 034 participants aged between 35-74 years completed a standardized 24-h d

Abstract in Danish I den vestlige del af Limfjorden findes en række kystklinter, hvor eocæne lag er blottet. Moler er en ca. 55-56 millioner år gammel diatomit, som indeholder lag af uforvitret vulkansk aske samt et stort antal velbevarede marine og terrestriske fossiler. Stolleklint Leret og Fur Formationen har et usædvanligt fossilselskab med mange repræsentanter for insekter, fisk, fugle og ski

Shock assisted ionization injection in laser-plasma accelerators.

Ionization injection is a simple and efficient method to trap an electron beam in a laser plasma accelerator. Yet, because of a long injection length, this injection technique leads generally to the production of large energy spread electron beams. Here, we propose to use a shock front transition to localize the injection. Experimental results show that the energy spread can be reduced down to 10

A matrix-free algorithm for multiple wavelength fluorescence tomography

In the recent years, there has been an increase in applications of non-contact diffusion optical tomography. Especially when the objective is the recovery of fluorescence targets. The non-contact acquisition systems with the use of a CCD-camera produce much denser sampled boundary data sets than fibre-based systems. When model-based reconstruction methods are used, that rely on the inversion of a

Drought, death and the sun in Ugarit and ancient Israel : A philological and comparative study

The sun and its heat are two of the most universal symbols known to humanity, yet their supposed meanings vary greatly. The sun can be thought of as a giver of life, but its hot and scorching rays can also be associated with drought and the powers of destruction. The present study concerns the latter view of the sun and related ideas as reflected in the Hebrew Bible and the cuneiform alphabetic te
