Patterns and magnitude of Zn:Ca in otoliths support the recent phylogenetic typology of Salmoniformes and their sister groups

La chimie des otolithes de poissons sert a associer les poissons a des environnements specifiques. La chimie des otolithes peut aussi potentiellement servir d'outil dans la recherche phylogenetique, comme nous le demontrons ici chez les poissons salmonides et les taxons apparentes. Des cartes bidimensionnelles de la chimie de Zn:Ca dans les otolithes montrent des oscillations annuelles d'amplitude

Can there only be one? Towards a post-paradigmatic service marketing approach

Purpose – The purpose of this paper is to unlock positions regarding the goods/services dichotomy in service marketing and to offer an argument that treats goods and services on an ontologically equal basis. Design/methodology/approach – A close reading of influential texts that argue in favor of a service-dominant logic (SDL) and new paradigms in service marketing. Findings – Both the SDL pro

Bratman, Searle, and Simplicity. A comment on Bratman, Shared Agency : A comment on Bratman, Shared Agency: A Planning Theory of Acting Together

Michael Bratman’s work is established as one of the most important philosophical approaches to group agency so far, and Shared Agency, A Planning Theory of Acting Together confirms that impression. In this paper I attempt to challenge the book’s central claim that considerations of theoretical simplicity will favor Bratman’s theory of collective action over its main rivals. I do that, firstly, by

Theoretical Characterization of the PC60BM:PDDTT Model for an Organic Solar Cell

We use time-dependent density functional theory together with a set of extensive multidimensional visualization techniques to characterize band gap, optical absorption properties, intramolecular and intern-wreaths charge transfer, exciton binding energy, charge transfer integral, and the rate of charge transfer and recombination in the PC60BM:PDDTT Model of an organic,solar cell. These theoretical

Women business ventures in Swedish university incubators

Purpose – Despite a growing interest in both women and university academic entrepreneurship, there are very few studies addressing women's academic entrepreneurship. The authors address this gap by focusing on university incubators for women's academic entrepreneurship. The purpose of this paper is to examine and analyze the significance of university incubators for the promotion and development o

Allelic variation at innate immune genes (avian beta-defensins), within a natural population of great tits

In order to fully understand pathogen induced natural variation in fitness in wild animal populations it is important to identify and study the degree of non-synonymous alleles in genes that code for components of the immune system. This study investigates the degree of natural genetic variation at 6 innate immune genes belonging to the -defensin family within a single population of birds, the gre

Mandibular widening in hemifacial microsomia: A roentgen stereometric study of 11 patients with the aid of metallic implants

Introduction: Our objective was to study mandibular widening in untreated subjects with hemifacial microsomia. Methods: From the 3-dimensional files at the Department of Plastic and Reconstructive Surgery, Skane University Hospital in Malmo, Sweden, data of 11 subjects (3 girls, 8 boys) with hemifacial microsomia were retrieved. Their age range was 9 years 2 months to 13 years 2 months at the firs

Patients' satisfaction after ear reconstruction with autologous rib cartilage.

Abstract Patients' satisfaction is an important outcome measure in reconstructive surgery and quality assurance is today central in the clinical practice. The aim of this study was to evaluate the patients' satisfaction with the process and final result after reconstruction for congenital microtia. A questionnaire was designed and sent to 78 patients who had undergone unilateral ear reconstruction

Exosomes reflect the hypoxic status of glioma cells and mediate hypoxia-dependent activation of vascular cells during tumor development.

Hypoxia, or low oxygen tension, is a major regulator of tumor development and aggressiveness. However, how cancer cells adapt to hypoxia and communicate with their surrounding microenvironment during tumor development remain important questions. Here, we show that secreted vesicles with exosome characteristics mediate hypoxia-dependent intercellular signaling of the highly malignant brain tumor gl

hENT1 expression is predictive of gemcitabine outcome in pancreatic cancer: A systematic review.

High human equilibrative nucleoside transporter 1 (hENT1)-expression has shown a survival benefit in pancreatic cancer patients treated with gemcitabine in several studies. The aim of this systematic review was to summarize the results and try to assess the predictive value of hENT1 for determining gemcitabine outcome in pancreatic cancer. Relevant articles were obtained from PubMed, Embase and Co

Influence of interface roughness in quantum cascade lasers

We use a numerical model based on non-equilibrium Green's functions to investigate the influence of interface roughness (IFR) scattering in terahertz quantum cascade lasers. We confirm that IFR is an important phenomenon that affects both current and gain. The simulations indicate that IFR causes a leakage current that transfers electrons from the upper to the lower laser state. In certain cases,

By Policy or Design? Privacy in the US in a Post-Snowden World

By drawing from a number of studies in the field as well as the Snowden revelations and the case of MegaUpload/MEGA, the article makes an analysis of relevant legislation on privacy in the digital context. The purpose of the analysis is to understand to what extent and how the current paradigm of privacy protection is, or is not, sufficient for contemporary needs. In particular, we ask how privacy

Patient-reported recovery after enhanced colorectal cancer surgery: a longitudinal six-month follow-up study.

The concept of enhanced recovery after surgery (ERAS) is a modern regime of care, and numerous studies have proved its beneficial impact on recovery after colorectal surgery. However, little is known about patients' continuing recovery after discharge. Therefore, the purpose of this study was to describe patient-reported recovery after colorectal cancer surgery in the context of ERAS from the day

Teaching extreme programming to large groups of students

We find the extreme programming methodology highly suitable for introducing undergraduate students to software engineering. To be able to apply this methodology at a reasonable teaching cost for large student groups, we have developed two courses that work in tandem: a team programming course taken by more than 100 students, and a coaching course taken by around 25 students. In this paper we descr

Method for the biological monitoring of hexahydrophthalic anhydride by the determination of hexahydrophthalic acid in urine using gas chromatography and selected-ion monitoring

A method for the determination of hexahydrophthalic acid, a metabolite of hexahydrophthalic anhydride, in human urine has been developed. The urine was worked-up by liquid-solid extraction, esterified with boron trifluoride-methanol, and analysed by capillary gas chromatography and selected-ion monitoring. Hexadeuterium-labelled hexahydrophthalic acid was used as the internal standard. The precisi

Curium isotopes in Chernobyl fallout

In nuclear reactors plutonium and transplutonium isotopes are produced by multiple neutron capture of uranium and plutonium and are important for the energy production and their composition reflects the core burnout. Under normal operation these elements are not released to the environment in significant amounts. There are accordingly very few areas or source terms where exotic transplutonium elem
