Phosphatidylethanol (PEth) is an abnormal phospholipid, formed only in the presence of ethanol via a transphosphatidylation reaction of phospholipase D (PLD). PEth in blood is a promising new marker of alcohol abuse. Blood PEth is found almost exclusively in red cells. This study was performed to investigate a possible PEth formation in human red cells from alcoholics and healthy individuals, at p

Recent advances in coherent multidimensional spectroscopy have boosted interest in exciton coherences in light harvesting complexes. We present nonperturbative calculations of two-dimensional (2D) electronic spectroscopy from a fifth-order phase-matching direction. The calculations show clear patterns that correspond to the electronic structure of one- and two-exciton manifolds of a Fenna-Matthews

nylinder p. (2011) Journal of Nursing Management19, 664-672 Perception of budgetary control: a study of differences across managers in Swedish public primary healthcare related to professional background and sex Background The composition of managers in Swedish public primary care centres has changed since the mid-1990s, favouring nurses and female managers. In parallel, health-care professionals

The acceptable noise level (ANL) test is used to quantify the amount of competing background noise (BNL) that a listener is willing to accept when listening to speech at the most comfortable level (MCL). ANL is calculated by subtracting the BNL from the MCL. Most studies show large intersubject ANL variability and a few also demonstrate large intrasubject variability. Very few predictor variables

Oat-based beverages enriched with vitamins and minerals were produced with common hydrothermal treatments and stored at 22 degrees C for 64 weeks. The effects of decanting on the retention of native vitamins, minerals and fatty acids, and different UHT holding time (5 s or 20 s) at 140 degrees C on vitamins were investigated. Fatty acid profile, vitamin retention and dissolved oxygen concentration

A new parameterization for copper at the INDO/CI level is presented. Results for excitation energies, ionization potentials, and electron detachment energies are presented for selected copper clusters with up to ten atoms. The parameterization gives improved results for calculations of spectroscopic properties for systems with significant copper-copper interactions, such as clusters and model surf

In this paper we derive a very useful formula for the stochastic representation of the product of a singular Wishart matrix with a normal vector. Using this result, the expressions of the density function as well as of the characteristic function are established. Moreover, the derived stochastic representation is used to generate random samples from product which leads to a considerable improvemen

We study the interaction of a transcritical (or saddle-node) bifurcation with a codimension-0/codimension-2 heteroclinic cycle close to (but away from) the local bifurcation point. The study is motivated by numerical observations on the traveling wave ODE of a reaction–diffusion equation. The manifold organization is such that two branches of homoclinic orbits to each fixed point are created when

Problem: What are the characteristics of Polykemi’s management control system and how is it affected by growth? Purpose: To describe and analyse the management control system of a medium-sized family-owned company from the perspective of Simons’ Levers of control. Research design: An abductive, interview-based case study of Polykemi AB. Conclusion: Polykemi’s management control system is primarily

The purpose of the study is to investigate how board structure influences CEO compensation for companies listed on the Stockholm Stock Exchange in 2004. The theoretical frame of reference is based upon the corporate governance theory, the principal-agent theory and previous empirical research in the area. A cross sectional regression analysis is used, where a number of control variables are includ

Human genetics is a powerful tool for discovering causal mediators of human disease and physiology. Cardiovascular diseases with late onset in the lifecourse have historically not been considered genetic diseases, but in recent years the contribution of a heritable factor has been established. More importantly, over the last decade genome-wide association studies (GWASs) have identified many loci

We propose an event-based account of the cognitive and linguistic representation of time and temporal relations. Human beings differ from nonhuman animals in entertaining and communicating elaborate detached (as opposed to cued) event representations and temporal relational schemas. We distinguish deictically based (D-time) from sequentially based (S-time) representations, identifying these with t

We consider the problem of computing all-pairs shortest paths in a directed graph with non-negative real weights assigned to vertices. For an n x n 0 - 1 matrix C, let K-C be the complete weighted graph on the rows of C where the weight of an edge between two rows is equal to their Hamming distance. Let MWT(C) be the weight of a minimum weight spanning tree of K-C. We show that the all-pairs short

This article proposes a novel theoretical framework for examining trust-repair discourse. The model identifies two fundamental discourse strategies available to the trust-breaker when trust is at stake (i) to engage with and act upon the discourses that represent a potential source of distrust - neutralize the negative, (ii) to communicate a trustworthy discourse identity - emphasize the positive.

Ethical issues in modern obstetrics commonly relate to a conflict between the rights and possibilities of the fetus versus those of the mother. After delivery, when the fetus by definition is a child, all legal rights are granted to this new individual. Whether any rights should be given or offered to the fetus is dependent on the prevailing situation. General rules are difficult to give due to th
