A stand-alone tree demography and landscape structure module for Earth system models

We propose and demonstrate a new approach for the simulation of woody ecosystem stand dynamics, demography, and disturbance-mediated heterogeneity suitable for continental to global applications and designed for coupling to the terrestrial ecosystem component of any earth system model. The approach is encoded in a model called Populations-Order-Physiology (POP). We demonstrate the behavior and per

Mapping the mechanics and macromolecular organization of hyaluronan-rich cell coats

The hyaluronan (HA)-rich pericellular coat (PCC) enveloping most mammalian cells plays a vital role in biological processes such as cell adhesion, proliferation, motility and embryogenesis. In particular its presence on chondrocytes, which live in the load-bearing cartilage, has a wide range of implications in diseases such as osteoarthritis, highlighting its mechanical role in living organisms. D

Alpha-ketoglutarate protects the liver of piglets exposed during prenatal life to chronic excess of dexamethasone from metabolic and structural changes

Glucocorticoids play a role in the origin of the features of the metabolic diseases. Alpha-ketoglutarate (AKG) is defined as glutamine homologue and derivative, conditionally an essential amino acid. In the liver, glutamine serves as a precursor for ureagenesis, gluconeogenesis and acute phase protein synthesis The aim of the study was to determine the effect of AKG administered to piglets prenata

Low sex hormone-binding globulin is associated with hypertension: a cross-sectional study in a Swedish population

Background: The aim of this study was to investigate the association of sex hormone-binding globulin (SHBG) and hypertension in a Swedish population. Methods: The study is based on a random sample of a Swedish population of men and women aged 30-74 years (n=2,816). Total testosterone, oestradiol and SHBG were measured in 2,782 participants. Free androgen index was then calculated according to the

Tema bokhistoria i Lychnos. Årsskrift för idé- och lärdomshistoria

Teknikerna att skriva och trycka eller med hjälp av andra grafiska metoder reproducera den mänskliga hjärnans produkter har och har haft en på alla plan genomgripande inverkan på hur samhället och kulturen formats och utvecklats. Att i idéhistorikernas årsbok erbjudas att göra ett temanummer om bokhistoria upplevde vi därför som speciellt roligt och utmanande. Här hade vi en arena där ljuset tradi

Search for displaced vertices arising from decays of new heavy particles in 7 TeV pp collisions at ATLAS

We present the results of a search for new, heavy particles that decay at a significant distance from their production point into a final state containing charged hadrons in association with a high-momentum muon. The search is conducted in a pp-collision data sample with a center-of-mass energy of 7 TeV and an integrated luminosity of 33 pb(-1) collected in 2010 by the ATLAS detector operating at

Enantioselective synthesis of anti-beta-amido-alpha-hydroxy esters via asymmetric transfer hydrogenation coupled with dynamic kinetic resolution

The asymmetric transfer hydrogenation of beta-amido-alpha-keto esters providing the corresponding anti-beta-amido-alpha-hydroxy esters via dynamic kinetic resolution is reported. The use of a commercially available, or simply prepared, chiral ruthenium catalyst results in good yields as well as high diastereoselectivities and enantioselectivities. (C) 2013 Elsevier Ltd.

Breastfeeding of preterm infants. Associated factors in infants, mothers, and clinical practice.

Abstract in Danish Amning har sundhedsmæssige fordele for mor og barn og mere udtalte fordele for præmature børn, men udenlandske undersøgelser viser, at færre præmature børn påbegynder amning, og færre præmature børn ammes i 4 og 6 måneder sammenlignet med mature børn. Der findes ikke danske undersøgelser om andelen af præmature børn, som påbegynder amning, men en dansk undersøgelse viser, at 60 Breastfeeding has even more pronounced health benefits for preterm infants than for full-term infants, but preterm infants are less breastfed. There is no consensus in Danish neonatal intensive care units (NICUs) about which clinical methods facilitate breastfeeding. Skin-to-skin contact between infant and parent is the first step in the breastfeeding process for preterm infants, but studies of to

An improved capillary model for describing the microstructure characteristics, fluid hydrodynamics and breakthrough performance of proteins in cryogel beds.

A capillary-based model modified for characterization of monolithic cryogels is presented with key parameters like the pore size distribution, the tortuosity and the skeleton thickness employed for describing the porous structure characteristics of a cryogel matrix. Laminar flow, liquid dispersion and mass transfer in each capillary are considered and the model is solved numerically by the finite

Mechanisms and Consequences of Chromosomal Instability in Malignant tumours

In this thesis, telomere deficiency with subsequent anaphase bridging was found to be associated with chromosomal instability in established colorectal cancer cell lines and in Wilms tumour. In colorectal cancer cell lines, anaphase bridging was observed to generate both numerical and structural chromosomal aberrations and was also associated with the presence of multipolar mitoses. In contrast to

Diabetes, healthcare cost and loss of productivity in Sweden 1987 and 2005-a register-based approach

Aim The aim of this study was to estimate healthcare cost and productivity losses as a result of diabetes and diabetes-related chronic complications in Sweden in 1987 and 2005. Research design and methods Published estimates on relative risks and Swedish age-specific diabetes-prevalence rates were used to calculate the proportions of diabetes-related chronic complications that are attributable to

Promises, Rights and Claims

Abstract in Undetermined The paper argues that promise rights presuppose independently existing (if not pre-existing) claims. The argument relies on the Bifurcation Thesis, according to which all claims, and all rights, can be exhaustively divided into two categories: capacity based and exercise based.

Multi-strange baryon production at mid-rapidity in Pb-Pb collisions at root s(NN)=2.76 TeV

The production of Xi(-) and Omega(-) baryons and their anti-particles in Pb-Pb collisions root s(NN) = 2.76 TeV has been measured using the ALICE detector. The transverse momentum spectra at mid-rapidity (vertical bar y vertical bar < 0.5) for charged Xi and Omega hyperons have been studied in the range 0.6 < P-T < 8.0 GeV/c and 1.2 < p(T) < 7.0 GeV/c, respectively, and in several centrality inter

Accuracy of advanced versus strictly conventional 12-lead ECG for detection and screening of coronary artery disease, left ventricular hypertrophy and left ventricular systolic dysfunction

Background: Resting conventional 12-lead ECG has low sensitivity for detection of coronary artery disease (CAD) and left ventricular hypertrophy (LVH) and low positive predictive value (PPV) for prediction of left ventricular systolic dysfunction (LVSD). We hypothesized that a similar to 5-min resting 12-lead advanced ECG test ("A-ECG") that combined results from both the advanced and conventional

Efficient Bounding of Displaced Bézier Patches

In this paper, we present a new approach to conservative bounding of displaced Bézier patches. These surfaces are expected to be a common use case for tessellation in interactive and real-time rendering. Our algorithm combines efficient normal bounding techniques, min-max mipmap hierarchies and oriented bounding boxes. This results in substantially faster convergence for the bounding volumes of di
