Migratory behaviour and otolith chemistry suggest fine-scale sub-population structure within a genetically homogenous Atlantic Cod population

The question whether temperate marine fishes typically consist of self-sustaining populations or "open" populations still remains unresolved. At the heart of this population connectivity problem lays the nature of the stock separation mechanisms. Fish populations could be segregated either by environmental forcing, accompanied with opportunistic recruitment of juveniles to spawning areas, or by ph

High-pressure structural behavior of large-void CoSn-type intermetallics: Experiments and first-principles calculations

The high-pressure structural behavior of the binary intermetallic compounds CoSn, FeSn, and NiIn with the peculiar void containing CoSn (B35)-type structure has been studied by means of room-temperature diamond anvil cell and high-temperature multianvil experiments, as well as by first-principles calculations. All three compounds remain structurally stable at pressures up to at least 25 GPa, where

Business services "in the making": (De)stabilisation of service definitions during the sourcing process

Recent studies suggest that service definition is an ongoing process, with service characteristics being temporarily stabilised and destabilised through buyer–service provider interactions. However, little is still known about how and, in particular, why services are (re)defined during the sourcing process, e.g., in terms of their intended outputs, how they are performed (processes), the inputs re

Mellan nation och omvärld : debatt i Sverige om vetenskapens organisering och finansiering samt dess internationella och nationella aspekter under 1900-talets första hälft

Between the nation and the surrounding world - Debate in Sweden regarding the organisation and financing of research and its international and national aspects during the first half of the twentieth century My thesis regards the attitude of the Swedish research society to research as a national and an international phenomenon during the period 1900-1950. My work relates to the question in which w

Two-pion Bose-Einstein correlations in central Pb-Pb collisions at root(NN)-N-S=2.76 TeV

The first measurement of two-pion Bose-Einstein correlations in central Pb-Pb collisions at root(NN)-N-S = 2.76 TeV at the Large Hadron Collider is presented. We observe a growing trend with energy now not only for the longitudinal and the outward but also for the sideward pion source radius. The pion homogeneity volume and the decoupling time are significantly larger than those measured at RHIC.

Soil erosion estimation based on rainfall disaggregation

Abstract in UndeterminedSoil loss estimation remains one of the most difficult research tasks all over the world. Current simulation tools are still not detailed enough to allow for realistic scenarios to handle soil erosion problems. A common problem is the lack of rainfall data at a sufficient level of detail. The present study uses a cascade disaggregation model to generate short time scale rai

Moderate hyperkalemia in hospitalized patients with cirrhotic ascites indicates a poor prognosis

Objective. Development of ascites in patients with liver cirrhosis is an ominous sign with a poor outcome. A liver transplantation must be considered, and it then becomes important to know if there are any factors indicating a worsened prognosis. Material and methods. We used official registers for a follow-up study of at least 5 years considering the prognosis of 155 prospectively recruited in-pa

Organizing disciplinary power in a knowledge organization

This article provides a systematic attempt to analyze the effects of performance appraisals, here conceptualized as tools for executing disciplinary power, and how the agency of employees is shaped. The article demonstrates how agency is enrolled by a broad set of disciplinary technologies aimed at behavior as well as the self, orchestrated in way that effectively short-circuits resistance. Drawin

Can a Chiral System Be Built on a Strongly Asymmetric Nucleon Configuration?

The multi-particle-plus-triaxial-rotor (MPR) model calculations were performed for several nuclei in the 100, 130 and 190 mass regions. It was found that chiral geometry can form even for very asymmetric nucleon configurations. However, the near-degeneracy of the partner bands may not be as good as the one observed for symmetric or slightly asymmetric configurations. DOI:10.5506/APhysPolB.44.341

Snake mitochondrial genomes: phylogenetic relationships and implications of extended taxon sampling for interpretations of mitogenomic evolution

Background: Snake mitochondrial genomes are of great interest in understanding mitogenomic evolution because of gene duplications and rearrangements and the fast evolutionary rate of their genes compared to other vertebrates. Mitochondrial gene sequences have also played an important role in attempts to resolve the contentious phylogenetic relationships of especially the early divergences among al

Competing water dissociation channels on rutile TiO2(110)

The interplay between two different water dissociation channels on rutile TiO2(110) was studied with the use of synchrotron radiation photoelectron spectroscopy. It was found that water dissociation at oxygen vacancies competes with water dissociation on defect-free regions such that one vacancy assisted dissociation event cancels one dissociation event on defect-free regions. The quenching affect

On the complexity of approximating the Hadwiger number

Unless P = NP there is no polynomial time approximation scheme (PTAS) for the problem of finding, for a graph G, the largest h such that the complete graph K-h is a minor of G. (C) 2008 Elsevier B.V. All rights reserved.

Prevalence of Tibiofemoral Osteoarthritis 15 Years After Nonoperative Treatment of Anterior Cruciate Ligament Injury: A Prospective Cohort Study.

BACKGROUND: The occurrence of osteoarthritis (OA), associated meniscal injuries, meniscectomy, and patient-related measures for patients treated nonoperatively after anterior cruciate ligament (ACL) injuries have not been well described in the literature in terms of natural history. HYPOTHESIS: Patients with ACL injury can achieve a low occurrence of tibiofemoral OA and good knee function when tre

Measurements of cold nuclear matter effects in J/Psi in the PHENIX experiment via deutron-gold collisions

A new calculation of RdAu has been performed using the 2003 d+Au data and the higher-statistics 2005 p+p data. These nuclear modification factors are compared to calculations using nuclear-modified PDFs and a J/ψ breakup cross section is extracted. These values are then used to project the cold nuclear matter effects in Au+Au collisions. Additionally, a more data-driven projection is performed.

Metabolic effects of furaldehydes and impacts on biotechnological processes.

There is a growing awareness that lignocellulose will be a major raw material for production of both fuel and chemicals in the coming decades-most likely through various fermentation routes. Considerable attention has been given to the problem of finding efficient means of separating the major constituents in lignocellulose (i.e., lignin, hemicellulose, and cellulose) and to efficiently hydrolyze

A Second Replicated Quantitative Analysis of Fault Distributions in Complex Software Systems

Background. Software engineering is in search for general principles that apply across contexts, for example to help guide software quality assurance. Fenton and Ohlsson presented such observations on fault distributions, which have been replicated once. Objectives.We intend to replicate their study a second time in a new environment. Method.We conducted a close replication, collecting defect data
