We present evidence for self-stabilization of the relative spectral phase of high-order harmonic emission against intensity variations of the driving field. Our results demonstrate that, near the laser focus, phase matching of the harmonic field from a macroscopic target can compensate for the intensity dependence of the intrinsic phase of the harmonics emitted by a single radiator. As a consequen

In Western educational systems, the question “Why study literature in school?” has been raised in connection with the theoretical development often summarized as “the cultural turn.” The author strives to contribute to this discussion by examining the development of educational discourse in Russia. During the Soviet period, literature was – together with history – the subject most heavily influenc

The ethanolic extract of the aerial parts from Mutisia orbignyana afforded two major compounds: mutisifurocoumarin (1) and 5-methylcoumarine-4-β-glucoside (2). The completely assignment of 1H and 13C NMR data of compound (2) is presented for the first time as well as some reassignments of 13C NMR spectrum for compound (1), applying 2D NMR techniques. In addition, the antiproliferative effect on co

Apolipoprotein M (ApoM) is a 25-kDa HDL-associated apolipoprotein and a member of the lipocalin family of proteins. Mature apoM retains its signal peptide, which serves as a lipid anchor attaching apoM to the lipoproteins, thereby keeping it in the circulation. Studies in mice have suggested apoM to be antiatherogenic, but its physiological function is yet unknown. We have now determined the 1.95

Lundh, L. G., Wångby-Lundh, M. & Bjärehed, J. (2011). Deliberate self-harm and psychological problems in young adolescents: Evidence of a bidirectional relationship in girls. Scandinavian Journal of Psychology. The purpose of this study was to test the hypotheses that there is a bidirectional prospective relationship between mental health and deliberate self-harm, in the sense that (1) psychol

INTRODUCTION. Prolonged cardiopulmonary resuscitation (CPR) with manual chest compressions (CC) during simultaneous percutaneous coronary intervention (PCI) is exceedingly difficult, with high mortality rates. The use of a mechanical CC (MCC) device can overcome the ordeal of manual CC. The aims of this thesis were to investigate the impact of the introduction of the LUCAS™ MCC device in the cath-

Maternal effects are ubiquitous in nature and affect a wide range of offspring phenotypes. Recent research suggests that maternal effects also contribute to ageing, but the theoretical basis for these observations is poorly understood. Here we develop a simple model to derive expectations for (i) if maternal effects on ageing evolve; (ii) the strength of maternal effects on ageing relative to dire

Business organizations may expand internationally by replicating a part of their value chain, such as a sales and marketing format, in other countries. However, little is known regarding how such "international replicators" build a format for replication, or how they can adjust it in order to adapt to local environments and under the impact of new learning. To illuminate these issues, we draw on a

The valence of the europium dopant and selected rare earth co-dopants (Ce3+, Dy3+, and Yb3+) in the Sr2MgSi2O7:Eu2+,R3+ persistent luminescence materials were studied by room temperature XANES measurements. The results indicated the co-existence of both divalent and trivalent europium in all the studied materials. The relative amount of Eu3+ was observed to increase upon increasing exposure to X-r

Identifying the relative importance of predation and resources in population dynamics has a long tradition in ecology, while interactions between them have been studied less intensively. In order to disentangle the effects of predation by juvenile fish, algal resource availability and their interactive effects on zooplankton population dynamics, we conducted an enclosure experiment where zooplankt

Eutrophication has been one of the largest environmental problems in aquatic ecosystems during the past decades, leading to dense, and often toxic, cyanobacterial blooms. In a way to counteract these problems many lakes have been subject to restoration through biomanipulation. Here we combine 13 years of monitoring data with experimental assessment of grazing efficiency of a naturally occurring zo

This report is a first attempt to use the design perspective we have developed in earlier reports in this series (Brehmer & Tehler, 2013: Tehler & Brehmer, 2013) in practical design of a system that would help Swedish County Administration Boards to meet their area responsibility in cases of major crises and accidents in their counties. The work starts with the development of a design hier
