Intercomparison of C-14 Dating of Wood Samples at Lund University and Eth-Zurich Ams Facilities: Extraction, Graphitization, and Measurement

We conducted an interlaboratory comparison between our radiocarbon-related research group at Lund University and the established ETH-Zurich facility to test the quality of the results obtained in Lund and to identify sources of potential background differences and scatter. We did find differences between the 2 laboratories in the contributions of chemical preparation, graphitization, and measureme

Alcohol consumption in relation to maternal deaths from induced-abortions in Ghana

Introduction: The fight against maternal deaths has gained attention as the target date for Millennium Development Goal 5 approaches. Induced-abortion is one of the leading causes of maternal deaths in developing countries which hamper this effort. In Ghana, alcohol consumption and unwanted pregnancies are on the ascendancy. We examined the association between alcohol consumption and maternal mort

Photoreceptor Cell Death Mechanisms in Inherited Retinal Degeneration

Photoreceptor cell death is the major hallmark of a group of human inherited retinal degenerations commonly referred to as retinitis pigmentosa (RP). Although the causative genetic mutations are often known, the mechanisms leading to photoreceptor degeneration remain poorly defined. Previous research work has focused on apoptosis, but recent evidence suggests that photoreceptor cell death may resu

Reagentless Amperometric Biosensor For Nadh Detection

A sensitive and selective amperometric biosensor, based on NADH-oxidase (NADOx) working in tandem with horseradish peroxidase (HRP), which is electrically connected to graphite electrode via Os-redox polymer (RP), was developed. Two designs were considered for the biosensor optimization: (i) the first one, [G/HRP-NADOx], exploited the direct electron transfer between HRP and the graphite electrode

The viscosity to entropy ratio from PHENIX data on single electron production

The PHENIX experiment has measured electrons from the decay of hadrons carrying heavy flavor (charm or bottom quarks) in p + p and Au + Au collisions at at the Relativistic Heavy Ion Collider (RHIC). The strong damping of heavy-flavor motion through the medium is reflected in a substantial suppression at high pT and a large azimuthal anisotropy v2 of such electrons in Au + Au collisions at RHIC. B

Effects of increasing doses of glucagon-like peptide-1 on insulin-releasing phases during intravenous glucose administration in mice

Chan HM, Jain R, Ahren B, Pacini G, D'Argenio DZ. Effects of increasing doses of glucagon-like peptide-1 on insulin-releasing phases during intravenous glucose administration in mice. Am J Physiol Regul Integr Comp Physiol 300: R1126-R1133, 2011. First published February 9, 2010; doi:10.1152/ajpregu.00687.2010.-The increase in insulin secretion caused by glucagon-like peptide-1 (GLP-1) and GLP-1 m

Mathematics: a female, male or gender-neutral domain? A study of attitudes among students at secondary level

The aim of the current study is to investigate whether Swedish secondary school students perceive mathematics as a female, male or gender-neutral domain. A sample of 1300 students in two age groups, 15- and 17-years, answered a questionnaire and about 50 students participated in interviews. The main part of the inquiry form consists of Who and mathematics, an attitude scale recently developed by o

Microbial fuel cell based biosensor for in situ monitoring of anaerobic digestion process.

A wall-jet microbial fuel cell (MFC) was developed for the monitoring of anaerobic digestion (AD). This biofilm based MFC biosensor had a character of being portable, short hydraulic retention time (HRT) for sample flow through and convenient for continuous operation. The MFC was installed in the recirculation loop of an upflow anaerobic fixed-bed (UAFB) reactor in bench-scale where pH of the ferm

Preterm intraventricular haemorrhage - Effects of extracellular haemoglobin

Popular Abstract in Swedish Framsteg inom neonatal intensivvård har ökat överlevnaden hos extremt för tidigt födda barn. Prognosen för dessa barn är generellt god, men 15-20 % av drabbas av en större hjärnblödning där blod tränger in i hjärnans hålrum, vilket innebär en sämre prognos och en ökad dödlighet. Av barnen som överlever drabbas hälften av en ökad huvudomfångstillväxt på grund av en tilltIntraventricular haemorrhage (IVH) is the most common brain lesion in preterm infants and is most commonly seen in the sickest children, with 15-20% of very preterm infants developing IVH. The mortality of infants with severe IVH is 20-50 % in the neonatal period and over 50 % of surviving infants develop post-haemorrhagic ventricular dilatation (PHVD) and 40-80 % develop severe neurological impai

Swedish Historical National Accounts, 1800-2000: Principles and Implications of a New Generation

A new set of data and estimates of historical national accounts for Sweden is concluded with the project Structural Change in the Swedish Economy, 1800-1980: Construction and Analysis of National Product Series. This article provides a short overview of earlier efforts, beginning in the 1930s, to construct historical national accounts and an account of the present project. The new estimates result

A geometry-based stochastic MIMO model for vehicle-to-vehicle communications

Vehicle-to-vehicle (VTV) wireless communications have many envisioned applications in traffic safety and congestion avoidance, but the development of suitable communications systems and standards requires accurate models for the VTV propagation channel. In this paper, we present a new wideband multiple-input-multiple-output (MIMO) model for VTV channels based on extensive MIMO channel measurements

Regulating Pharmaceutical Industry Marketing: Development, Enforcement and Outcome of Marketing Rules

This essay reviews work in sociology and cognate fields regarding pharmaceutical marketing and its regulation. In particular, it considers how this literature contributes to a better understanding of the process of pharmaceuticalization, defined as “the translation or transformation of human conditions, capabilities, and capacities into opportunities for pharmaceutical intervention.” The review ad

An Evaluation of Potential Benefits of Mobile BI

The new generation of mobile devices, such smartphones and tablets, make users no longer constrained to traditional devices, such as PCs and laptops, in order to access needed information. This has given rise to an innovation in Business Intelligence (BI) coined mobile BI, which is currently embraced by different organizations. Information systems (IS) innovations are in general accompanied by “bu
