Haematopoietic stem cells : Entropic landscapes of differentiation

The metaphor of a potential epigenetic differentiation landscape broadly suggests that during differentiation a stem cell approaches a stable equilibrium state from a higher free energy towards a stable equilibrium state which represents the final cell type. It has been conjectured that there is an analogy to the concept of entropy in statistical mechanics. In this context, in the undifferentiated

Wind Turbine Noise and Sleep : Pilot Studies on the Influence of Noise Characteristics

The number of onshore wind turbines in Europe has greatly increased over recent years, a trend which can be expected to continue. However, the effects of wind turbine noise on long-term health outcomes for residents living near wind farms is largely unknown, although sleep disturbance may be a cause for particular concern. Presented here are two pilot studies with the aim of examining the acoustic

Binding of 14C-labeled food mutagens (IQ, MeIQ, MeIQx) by dietary fiber in vitro.

Binding of three mutagens, known to occur in fried or broiled foods, by thirteen different types of dietary fiber was investigated in vitro. Nonspecific binding by other food polymers was minimized by using protease and amylase treatment. Water‐insoluble fiber components were responsible for most of the binding capacity. Generally, a slightly larger proportion of 2‐amino‐3,4‐dimethylimidazo [4,5‐f

Innovation policy for system-wide transformation : The case of strategic innovation programmes (SIPs) in Sweden

The orientation towards grand societal challenges can be seen as a new wave or paradigm for innovation policy. Such policy aims at system-wide transformation and is often referred to as system innovation policy. While insights from transition studies have provided novel and useful rationales for innovation policy targeting system-wide transformation, it remains unclear how to design, implement and

Neuropeptides in the human appendix - Distribution and motor effects

At present our knowledge of enteric peptide-containing neurons in man is limited. In this study we have used human appendices removed at surgery to examine the peptidergic innervation by immunocytochemistry, immunochemistry, and pharmacological in vitro experiments. Immunocytochemistry revealed a variety of peptide-containing nerve fiber populations in the human appendix. VIP/PHI-, VIP/PHI/NPY-, S

The Social Capability Index and Income Convergence

Domestic social capabilities are a set of national characteristics for understanding why some countries grow faster than others. Yet there is no clear agreement on the main characteristics of these capabilities and therefore they have been neglected in the income convergence debate. The paper presents an index for revisiting the role of social capabilities in this debate. A relatively socially adv

Reducing energy-related negative externalities with market-based instruments

The purpose of this chapter is to contribute to the literature on the economics of public policy interventions in relation externalities. The chapter presents some theoretical constructs and evaluates the potential contribution of market-based instruments, either by avoiding negative externalities or boosting positive ones. The author takes the topical issue of 'Markets for Energy Efficiency' as t

Socioeconomic factors and mortality in patients with atrial fibrillation-a cohort study in Swedish primary care

Background: Preventing ischaemic stroke attracts significant focus in atrial fibrillation (AF) cases. Less is known on the association between socioeconomic factors and mortality and cardiovascular outcomes in patients with AF. Methods: Our study population included adults (n=12 283) ≥45 years diagnosed with AF at 75 primary care centres in Sweden 2001-07. Cox regression was used to calculate haza

Massive MIMO for Ray-Based Channels

Favorable propagation (FP) and channel hardening are desired properties in massive multiple-input and multiple-output (MIMO) systems, where nearly optimal performance is achieved with linear processing techniques, such as maximal-ratio combining. To date, these properties have primarily been analyzed for statistical channel models, or ray-based models with very specific angular parameters and dist

Modeling and synchrotron imaging of droplet detachment in gas channels of polymer electrolyte fuel cells

A computational fluid dynamics model of a channel (one liquid inlet, one liquid inlet and one two-phase outlet), applicable for PEFC gas channel water transport, is developed. A volume of fluid approach is used to study the two-phase flow behavior (interface-resolved) inside the gas channel, including the surface of GDL (gas diffusion layer), which is verified by experimental results from synchrot

A method for tumor dosimetry based on hybrid planar-SPECT/CT images and semiautomatic segmentation

Purpose: A hybrid planar-SPECT/CT method for tumor dosimetry in 177Lu-DOTATATE therapy, applicable to datasets consisting of multiple conjugate-view images and one SPECT/CT, is developed and evaluated. Methods: The imaging protocol includes conjugate-view imaging at 1, 24, 96, and 168 h post infusion (p.i.) and a SPECT/CT acquisition 24 h p.i. The dosimetry method uses the planar images to estimat

Genetic variation associated with chromosomal aberration frequency : A genome-wide association study

Chromosomal aberrations (CAs) in human peripheral blood lymphocytes (PBL) measured with the conventional cytogenetic assay have been used for human biomonitoring of genotoxic exposure for decades. CA frequency in peripheral blood is a marker of cancer susceptibility. Previous studies have shown associations between genetic variants in metabolic pathway, DNA repair and major mitotic checkpoint gene

Affectual Demands and the Creative Worker: Experiencing Selves and Emotions in the Creative Organization

Creative workers are increasingly called upon to engage affectually with their work through discourses that demand a love or passion for one’s work. In an organisational setting, these discourses can collapse the distance between selves and work, heightening the sense of personal meaningfulness derived from work. However, these discourses can also be used to discipline an organisationally desirabl
