Changing borders of control and publicness : A study of a Swedish housing area in Lund 1970-2015.

In this article, I investigate the slowly changing territorial landscape of a seemingly typical Swedish Million program housing area (from the record years 1961-1975), Norra Fäladen in Lund. The area has, through the decades, been subject to a slow, but steady gentrification and densification including a decrease in rental housing and the building on former park areas. Through the decades we have

Olivine on Vesta as exogenous contaminants brought by impacts : Constraints from modeling Vesta's collisional history and from impact simulations

The survival of asteroid Vesta during the violent early history of the Solar System is a pivotal constraint on theories of planetary formation. Particularly important from this perspective is the amount of olivine excavated from the vestan mantle by impacts, as this constrains both the interior structure of Vesta and the number of major impacts the asteroid suffered during its life. The NASA Dawn

For whom is a health-promoting intervention effective? : Predictive factors for performing activities of daily living independently

BACKGROUND: Health-promoting interventions tailored to support older persons to remain in their homes, so-called "ageing in place" is important for supporting or improving their health. The health-promoting programme "Elderly Persons in the Risk Zone," (EPRZ) was set up for this purpose and has shown positive results for maintaining independence in activities of daily living for older persons 80 y

Material Properties and Full-Scale Rain Exposure of Lime-Hemp Concrete Walls : Measurements and Simulations

Lime-hemp concrete (LHC) is a building material consisting of a lime-based binder combined with hemp shiv that is suitable for various building applications. This thesis aimed to elucidate the possibilities for using LHC for exterior walls in a cold, wet climate through investigating mechanical, thermal and moisture-related properties of the material. The mechanical properties of LHC containing bo

Photon Splatting Using a View-Sample Cluster Hierarchy

Splatting photons onto primary view samples, rather than gathering from a photon acceleration structure, can be a more efficient approach to evaluating the photon-density estimate in interactive applications, where the number of photons is often low compared to the number of view samples. Most photon splatting approaches struggle with large photon radii or high resolutions due to overdraw and insu

Component Importance for Multi-Commodity Networks: Application in the Swedish Railway

Preparedness and resilience planning for critical infrastructure networks requires evaluating the impact to the network when its components are disrupted. We extend the well-studied problem of component importance measures in single-commodity networks to multi-commodity networks by integrating a flow based multi-commodity optimization model with a multi-criteria decision analysis tool. A three-sta

A Method for Assessing Margin and Sensitivity of Electricity Networks With Respect to Repair System Resources

Modern society is becoming increasingly dependent on a continuous supply of electricity. In order to maintain the safety and security of society and its citizens, it is therefore necessary that electricity networks are resilient toward disruptions whether caused by natural disasters, sinister attacks, or other. Margin and sensitivity are two crucial aspects of the resilience concept which have so

Surface structure and catalytic activity of Pd and Fe oxide surfaces and thin films

Catalytic processes have tremendous importance in our everyday life. Most chemicals, pharmaceuticals, plastics etc. are, in fact, produced with the help of catalysts. What is probably even more important is that the toxic wastes produced in great amounts by modern factories and plants are recycled or transformed into less poisonous substances by means of catalytic units. One example from our everyThe present work is devoted to atomic scale structural studies of the surfaces of model heterogeneous catalysts relevant to oxidation reactions. A novel approach using high-energy surface X-ray diffraction combined with mass-spectrometry measurements is employed to perform in situ structural characterization of Pd(100) and Pd(553) single crystal surfaces acting as catalysts in the process of CO ox

Macrophage CD74 contributes to MIF-induced pulmonary inflammation

BACKGROUND: MIF is a critical mediator of the host defense, and is involved in both acute and chronic responses in the lung. Neutralization of MIF reduces neutrophil accumulation into the lung in animal models. We hypothesized that MIF, in the alveolar space, promotes neutrophil accumulation via activation of the CD74 receptor on macrophages.METHODS: To determine whether macrophage CD74 surface ex

Capturing Societal Interdependencies from a Flow Perspective – Part I: Method and Model

A method and a model are presented aiming at enabling collection, structuring and analyzes of data concerning interdependencies between critical infrastructures and societal functions. A key distinction of the approach is the separation of actors and flows, where dependencies between actors, ranging from small municipal authorities to international private companies, are mediated through flows. Fl

Strain differences in alveolar neutrophil infiltration and macrophage phenotypes in an acute lung inflammation model

Pulmonary infection is a major cause of mortality and morbidity, and the magnitude of the lung inflammatory response correlates with patient survival. Previously, we have shown that neutrophil migration into joints is regulated by arthritis severity quantitative trait loci (QTLs). However, it is unclear whether these QTLs contribute to the regulation of lung inflammation in pneumonias. Therefore,

Age influences inflammatory responses, hemodynamics, and cardiac proteasome activation during acute lung injury

BACKGROUND: Acute lung injury (ALI) is a significant source of morbidity and mortality in critically ill patients. Age is a major determinant of clinical outcome in ALI. The increased ALI-associated mortality in the older population suggests that there are age-dependent alterations in the responses to pulmonary challenge. The objective of this observational study was to evaluate age-dependent diff

Age-dependent alterations in the inflammatory response to pulmonary challenge

The aging lung is increasingly susceptible to infectious disease. Changes in pulmonary physiology and function are common in older populations, and in those older than 60 years, pneumonia is the major cause of infectious death. Understanding age-related changes in the innate and adaptive immune systems, and how they affect both pulmonary and systemic responses to pulmonary challenge are critical t

Capturing Societal Interdependencies from a Flow perspective – Part II: Application

Societal functions constitute of public and private organisations and companies that provide commodities and services that are vi-tal for the functioning of the modern society. The public are highly dependent on these vital societal services and commodities, such as power supply, health care and education. In this paper we present an application of a method for collecting and structuring data and

N-Ethylmaleimide Sensitive Factor (NSF) Inhibition Prevents Vascular Instability following Gram-Positive Pulmonary Challenge

BACKGROUND: The Acute Respiratory Distress Syndrome (ARDS), remains a significant source of morbidity and mortality in critically ill patients. Pneumonia and sepsis are leading causes of ARDS, the pathophysiology of which includes increased pulmonary microvascular permeability and hemodynamic instability resulting in organ dysfunction. We hypothesized that N-ethylmaleimide sensitive factor (NSF) r

Regulation of angiopoietin-2 secretion from human pulmonary microvascular endothelial cells

INTRODUCTION: Sepsis is characterized by dysregulated systemic inflammation and cytokine storm. Angiopoietin-2 (Ang-2) is known to closely correlate with severity of sepsis-related acute lung injury and mortality. The aim of this study was to clarify the mechanisms involved in Ang-2 secretion to better understand the pathophysiology of sepsis.MATERIALS AND METHODS: The concentration of Ang-2 was a

Review of methods for measuring societal resilience and how they address critical infrastructures

The review presented in this paper aims to describe the state-of-the art concerning methods for measuring societal resilience. A literature search is conducted where 36 recently published methods are selected. Then, various questions are explored concerning the methods, such as how resilience is operationalized, how data is collected, and about their normative foundation. Several methods exist wit
