Complications and survival after surgical treatment of 214 metastatic lesions of the humerus

Background: The humerus is the second most common long-bone site of metastatic bone disease. We report complications, risk factors for failure, and survival of a large series of patients operated on for skeletal metastases of the humerus. Materials and methods: This study was based on 208 patients treated surgically for 214 metastatic lesions of the humerus. Reconstructions were achieved by intram

Multimodal Retrieval of Autobiographical Memories: Sensory Information Contributes Differently to the Recollection of Events

Previous studies on autobiographical memory have focused on unimodal retrieval cues (i.e., cues pertaining to one modality). However, from an ecological perspective multimodal cues (i.e., cues pertaining to several modalities) are highly important to investigate. In the present study we investigated age distributions and experiential ratings of autobiographical memories retrieved with unimodal and

Motivation crowding by economic incentives in conservation policy: A review of the empirical evidence

The paper seeks to advance our understanding of the extent to which the use of economic incentives can undermine ("crowd out") or reinforce ("crowd in") people's intrinsic motivations to engage in biodiversity and ecosystem conservation. We first synthesize and classify the psychological mechanisms behind motivation crowding effects. Then we conduct a systematic review of empirical studies that te

Growth response of the bacterial community to pH in soils differing in pH

The effect of pH on the instantaneous growth of soil bacterial communities was studied in five soils with different pH (4.5-7.8) using leucine (Leu) and thymidine (TdR) incorporation. The pH dependency of bacterial growth was modelled using three different unimodal functions, and the pH(opt) for growth and the pH range in which growth was > 50% of the optimal growth were compared. Leu and TdR inco

Obstacles to Developing Recreational Fishing Enterprises in Sweden

The Swedish government has a stated objective of developing the recreational fishing industry, not least with respect to employment opportunities in rural areas. This paper analyzes the possibilities for governmental policies to enhance the development. After asking companies what obstacles they view as problematic for running their business, four challenges are analyzed; lack of fish, lack of lar

High Frequency Performance of Vertical InAs Nanowire MOSFET

We report on RF characterization of vertical, 100-nm-gate length InAs nanowire MOSFETs, utilizing wrap-gate technology and Al2O3 high-kappa gate oxide. The transistors show f(t)=5.6 GHz and f(max)=22 GHz, mainly limited by parasitic capacitances. The RF device performance is described using a hybrid-pi model taking hole generation at the drain into account. Electrostatic modeling of the parasitic

Low temperature deposition of silicon nitride using Si3Cl8

We demonstrate the deposition of SixNy thin films using octachlorotrisilane (Si3Cl8) and ammonia between 300 and 500 degrees C by an atomic layer deposition-like growth mechanism. Although there are chemical vapor deposition growth mechanisms present, which lead to an incomplete saturation, a step coverage >80% in high aspect ratio (>60:1) trenches could be achieved. The deposited films oxidize af

Increased Fibrosis and Interstitial Fluid Pressure in Two Different Types of Syngeneic Murine Carcinoma Grown in Integrin beta 3-Subunit Deficient Mice

Stroma properties affect carcinoma physiology and direct malignant cell development. Here we present data showing that alpha(V)beta(3) expressed by stromal cells is involved in the control of interstitial fluid pressure (IFP), extracellular volume (ECV) and collagen scaffold architecture in experimental murine carcinoma. IFP was elevated and ECV lowered in syngeneic CT26 colon and LM3 mammary carc

Structural and magnetic dynamics in the magnetic shape-memory alloy Ni2MnGa

Magnetic shape-memory Heusler alloys are multiferroics stabilized by the correlations between electronic, magnetic, and structural order. To study these correlations we use time-resolved x-ray diffraction and magneto-optical Kerr effect experiments to measure the laser induced dynamics in a Heusler alloy Ni2MnGa film and reveal a set of time scales intrinsic to the system. We observe a coherent ph

Upploppskulturer : Stockholm och landsort i svenska 1800-talsupplopp

This article categorizes all 96 known riots in Sweden between 1793 and 1869, from the perspective of the goals of the participants. Three quarters of all riots were either reactions to actions by government agents or based on a moral economy as discussed by E. P. Thompson in his classic article. Such riots, common in the provinces, were next to non-existent in Stockholm, however. In the capital, r

Study of a high spatial resolution B-10-based thermal neutron detector for application in neutron reflectometry: the Multi-Blade prototype

Although for large area detectors it is crucial to find an alternative to detect thermal neutrons because of the He-3 shortage, this is not the case for small area detectors. Neutron scattering science is still growing its instruments' power and the neutron flux a detector must tolerate is increasing. For small area detectors the main effort is to expand the detectors' performances. At Institut La

Decline in Titers of Anti-Idiotypic Antibodies Specific to Autoantibodies to GAD65 (GAD65Ab) Precedes Development of GAD65Ab and Type 1 Diabetes.

The humoral Idiotypic Network consisting of antibodies and their anti-idiotypic antibodies (anti-Id) can be temporarily upset by antigen exposure. In the healthy immune response the original equilibrium is eventually restored through counter-regulatory mechanisms. In certain autoimmune diseases however, autoantibody levels exceed those of their respective anti-Id, indicating a permanent disturbanc

X-Ray Diagnostics in Combustion - Study of Particle Formation in Flames Using Combined Small- and Wide-Angle X-Ray Scattering

Popular Abstract in Swedish Vid förbränning av bränslen som innehåller kol, till exempel ved, olja och biobränslen, bildas sotpartiklar då det finns ett underskott av syre, så kallad ofullständig förbränning. Det är sotpartiklarna i brasan som ger dess gula sken. Dessa partiklar är små och består till största delen av oförbränt kol från bränslet. De små sotpartiklarna är hälsofarliga då de följer In the thesis work, two X-ray scattering techniques, small- and wide-angle X-ray scattering (SAXS and WAXS) were combined to study particle formation in-situ and non-intrusively in ethylene laboratory flames. Combining these two techniques enabled information concerning the size and concentration as well as the subnanometer structure of the nanoparticles within the 1–100 nm range there to be obtai

The Estonian forest sector in transition to sustainability? : Capturing sustainability with the help of integrated assessment

This thesis has two main objectives. The first is to analyse the potential of existing assessment tools and methods to incorporate the different dimensions of sustainability in an assessment. The second is to apply some of these tools in a case study in order to determine how forest sector can better contribute to sustainable development in Estonia. The first aim is addressed in a theoretical sect

Geographic and Habitat Origin Influence Biomass Production and Storage Translocation in the Clonal Plant Aegopodium podagraria.

Through physiological integration, clonal plants can support ramets in unfavourable patches, exploit heterogeneously distributed resources and distribute resources that are taken up over large areas. Physiological integration generally increases in adverse conditions, but it is not well known which factors determine the evolution of physiological integration. The aim of this study was to investiga
