We report a solid smectic phase that exhibits dodecagonal global order. It is composed of axially stacked hexagonally ordered particle layers, and its 12-fold rotational symmetry induced by the 30° rotation of adjacent layers with respect to each other. A quasicrystal was produced in a molecular-dynamics simulation of a single-component system of particles interacting via a spherically-symmetric p
In 2003 Newmont has signed an investment agreement with the government of Ghana that resulted in the inauguration in 2006 of the large, gold-producing project at Ahafo. The challenge for Newmont has been to resolve the initial conflict resulting from a land dispossession that brought communities close to famine and address the lingering tensions by working towards sustainable solutions. This artic
The aim of this paper is directly linked to the context within which it has been drafted, as ecological debt (including climate debt) has been identified as a key Ejolt concept, one that is in need of better elucidation if EJOs are to operationalize its possibilities in their ongoing activities. Readers of this paper (and especially EJO activists) should in this way not only find themselves introd
The state-of-the-art in development tools today provides users with a large number of both syntactic and semantic services, such as syntax highlighting, name completions and refactorings. Preferably, every language should have sophisticated tool support, but unfortunately, the manual task of tool development is both time-consuming and error-prone, making it too costly for small language communitie
Objective: High fractions of inspired oxygen (FIO2) used in acute lung injury (ALI) may promote resorption atelectasis. The impact of derecruitment related to high FIO2 in ALI is debated. We evaluated derecruitment with 100% vs. 60% FIO2 at two levels of positive end-expiratory pressure (PEEP). Patients: Fourteen consecutive patients with ALI were studied. Interventions: Recruited volume at two PE
Research in avian blood parasites has seen a remarkable increase since the introduction of polymerase chain reaction-based methods for parasite identification. New data are revealing complex multihost-multiparasite systems which are difficult to understand without good knowledge of the host range and geographical distribution of the parasite lineages. However, such information is currently difficu
Background Estimation of skin diseases in the community is challenging because we do not easily have access to the nonhealthcare-seeking population. A potential tool is a questionnaire asking for self-reported skin complaints. Such an instrument has not yet been developed. Objectives To validate a simple instrument assessing skin morbidity in the general adult population, to predict clinical skin
There are accelerating trends for the implementation of electronic commerce(e-commerce) as an extra marketing channel for selling products globally via the access of the Internet. This is expected to in¯uence the shape of future cities and the conservation of natural resources. This paper critically reviews the current research work to date regarding the environmental implications of e-commerce. T
AIM: To investigate plasma levels of the neutrophil-borne heparin-binding protein (HBP) in patients with induced hypothermia after cardiac arrest (CA), and to study any association to severity of organ failure, incidence of infection and neurological outcome. METHODS: This study included 84 patients with CA of mixed origin who were treated with hypothermia. Plasma samples from 7 time points during
This is a study of the intersubjective recognizability of the “proper” accomplishment of children’s actions, and in particular of how the status of actions as properly completed is often actively made recognizable through speech and various modulations of bodily movement. In addition to analyzing how children do this in a number of cases, it is also argued that these manifestations of action compl
Iterative reconstruction has a wide spectrum of proven advantages in the field of conventional X-ray absorption-based computed tomography (CT). In this paper, we report on an algebraic iterative reconstruction technique for grating-based differential phase-contrast CT (DPC-CT). Due to the differential nature of DPC-CT projections, a differential operator and a smoothing operator are added to the i
The continuously increasing solid waste generation worldwide calls for management strategies that integrate concerns for environmental sustainability. By quantifying environmental impacts of systems, life cycle assessment (LCA) is a tool, which can contribute to answer that call. But how, where and to which extent has it been applied to solid waste management systems (SWMSs) until now, and which l
The development of cellulose dissolution/regeneration strategies constitutes an increasingly active research field. These are fundamental aspects of many production processes and applications. A wide variety of suitable solvents for cellulose is already available. Nevertheless, most solvent systems have important limitations, and there is an intense activity in both industrial and academic researc
Aims: To evaluate outcome in the first generation of children with end-stage heart disease to whom heart transplantation was available. Methods: Retrospective review of all 135 Swedish children <18 years old listed for heart transplantation 1989-2009, followed to December 31, 2009, including 74 (55%) with cardiomyopathy and 61 (45%) with congenital heart disease; 34 (25%) were infants (<1 year). C
Results are presented on the production of jets of particles in association with a Z/gamma* boson, in proton-proton collisions at root s = 7 TeV with the ATLAS detector. The analysis includes the full 2010 data set, collected with a low rate of multiple proton-proton collisions in the accelerator, corresponding to an integrated luminosity of 36 pb(-1). Inclusive jet cross sections in Z/gamma* even
The purpose of this study was to compare the non-invasive 3D pseudo-continuous arterial spin labelling (PC ASL) technique with the clinically established dynamic susceptibility contrast perfusion magnetic resonance imaging (DSC-MRI) for evaluation of brain tumours. A prospective study of 28 patients with contrast-enhancing brain tumours was performed at 3 T using DSC-MRI and PC ASL with whole-brai
