Calcium sulfate/hydroxyapatite (CaS/HA) biomaterials have been investigated for use in several orthopedic applications. However, the mechanical interactions between the composite of CaS/HA and bone at the microscale are still unknown. The aim of this study was to determine if and how augmentation with CaS/HA alters the fracture behavior of bone. Eleven cylinders of trabecular bone were drilled fro
Coronavirus disease 2019 (COVID-19) has caused global disruption and a significant loss of life. Existing treatments that can be repurposed as prophylactic and therapeutic agents may reduce the pandemic’s devastation. Emerging evidence of potential applications in other therapeutic contexts has led to the investigation of dietary supplements and nutraceuticals for COVID-19. Such products include v
Background: We set out to estimate net survival trends for 10 common cancers in 279 cancer registry populations in 67 countries around the world, as part of the CONCORD-2 study. Net survival can be interpreted as the proportion of cancer patients who survive up to a given time, after eliminating the impact of mortality from other causes (background mortality). Background mortality varies widely be
We report here on a diagnostic tool for improving doctoral supervision that supervisors in training at Lund University use to develop strategies for supporting their student’s learning. The tool has been developed by combining two theoretical models, an empirically generated model of orientations to doctoral supervision (Lee, 2008) and a meta-perspective on professional learning (Dall'Alba & S
Objective: To describe beliefs about health and illness among foreign-born people with diabetic foot ulcers that might affect selfreported self-care and health-care seeking and to study whether there are dissimilarities related to origin. Method: Qualitative descriptive study. Semi-structured interviews with people aged 38-86 years; 13 born in European and 13 in non-European countries (all except
The Sustainable Development Goals (SDGs) require nations to ensure adequate water supply for all. For Kazakhstan, this means that rural areas will need much stronger attention as they have been rather neglected in efforts to comply with the Millennium Development Goals (MDGs). This study aims to establish a baseline data concerning the current situation in villages that will need interventions acc
Electrical machines, chokes and induction heaters are found in most homes,offices and factories all over the world. They are used to create movement, filtrate the power or to generate heat. A typical unit consist of a coil and a flux conductor material. Some of the materials have been established for over 100 years, while others are only a couple of decades old.A new flux conductor material has be
När vi människor försöker röra på oss skickas elektriska impulser genom nervsystemet från hjärnan ner till de muskler som är inblandade i den tilltänkta rörelsen. Att kunna mäta sådana nervimpulser hade varit av värde för en rad tillämpningar—information hade då kunnat överföras direkt från nervsystemet utan att gå via långsamma, mekaniska gränssnitt så som tangentbord och pekskärmar. OlyckligtvisElectrical activity produced by muscles during voluntary movement is a reflection of the firing patterns of relevant motor neurons and, by extension, the latent motor intent driving the movement. Once transduced via electromyography (EMG) and converted into digital form, this activity can be processed to provide an estimate of the original motor intent and is as such a feasible basis for non-invas
Sustainable practices are increasingly promoted in the restaurant industry. One significant aspect of sustainability in restaurants is the use of local supply chains, especially for food, which also serve as a means for restaurants to promote freshness of produce, sourcing, and quality. Considering the prevalence of locality in menu marketing, this study aims to explore the relationships between s
There is growing concern about the possible hazards which can result from the use of certain organic building materials. The issue has received a great deal of attention in industrial countries in temperate climates, because indoor air pollution is frequent in tight, energy efficient buildings with low rates of ventilation. This is not yet a problem all over the world, but an awareness of the risk
BackgroundPostzygotic isolation in the form of reduced viability and/or fertility of hybrids may help maintain species boundaries in the face of interspecific gene flow. Past hybridization events between house sparrows (Passer domesticus) and Spanish sparrows (P. hispaniolensis) have given rise to a homoploid hybrid species, the Italian sparrow (P. italiae). Although genetic incompatibilities are
Microbial necromass contributes significantly to both soil carbon (C) persistence and ecosystem nitrogen (N) availability, but quantitative estimates of C and N movement from necromass into soils and decomposer communities are lacking. Additionally, while melanin is known to slow fungal necromass decomposition, how it influences microbial C and N acquisition as well as elemental release into soils
Electrifying road transport is seen as one of the key components in decreasing the carbon footprint of the society as a whole. Recent developments in electric drivetrain and battery technology have helped to design vehicles with ranges that make them independent of public charging infrastructure during most sub-urban and commuting trips. Once long-haul trips are planned, however, these vehicles re
From the starting point of narrative ethnography, this article explores a specific kind of service user involvement in psychiatry: staff training activities in which patients and former patients are invited to “tell their stories”. A core feature of these stories is that they are based on the narrators’ self-perceived experience, and they all have a highly personal character. I call these stories
The purpose with this thesis is to give the reader a holistic view of the 3D-print technology and how it can come to use in the construction industry. The purpose is also to spread knowledge about the technology. During the evaluation of the technology examines four aspects that an innovation needs to establish on the market, the aspects are: geographical resources, economical, law and social impa
Popular Abstract in English The word “combustion” describes a number of physical and chemical processes, whose common characteristic is an interaction between fuel and oxygen and their subsequent transformation into products, such as CO2 and water. Even though the process is often described as a single chemical reaction between fuel and oxygen, in reality, their chemical transformation requires maThe laminar burning velocity and the flame structure are common targets for combustion studies aimed at detailed kinetic model development. In the present work, fuels relevant to hydrogen combustion were considered. The laminar burning velocity of rich and lean hydrogen flames was studied experimentally and numerically, including its pressure dependence in rich mixtures and temperature dependence
Popular Abstract in Swedish Idag röker cirka 6% av alla gravida kvinnor i Sverige. I vissa regioner är andelen så hög som en av tio gravida kvinnor. Trots att det betyder att det har skett en kraftig nedgång sedan man började mäta utbredningen av graviditetsrökning i början på 80-talet, visar siffror att denna nedgång verkar ha avstannat. Det är känt sedan länge att rökning under graviditeten är sGlobally, around 10 % of women smoke during pregnancy today. It is known that pregnancy smoking increases the risk of adverse short-term health effects in the offspring, such as preterm birth, low birthweight and spontaneous abortion. Less is known about whether any adverse health effects persist until adulthood. In Sweden, there are nationwide population-based health registers that are becoming i
As the highest level of cloud computing delivery model, Software-as-a-Service (SaaS) has gained considerable popularity in the industry as a new way of deploying IT solutions, due to its low cost and high elasticity. However, the new business model associated with SaaS highlights the importance for SaaS vendors to understand how to retain customers in a hyper-competitive market. In particular, inc
Whilst it is increasingly recognised that socio-political contexts shape climate change adaptation decisions and actions at all scales, current modes of development typically fail to recognise or adequately challenge these contexts where they constrain capacity to adapt. To address this failing, we consider how a rights-based approach broadens understanding of adaptive capacity while directing att
The EU’s Common Security and Defence Policy was created to stabilize the EU’s Neighbourhood, fuel the EU’s geopolitical crisis management ambitions, and strengthen European values abroad. In the recent debate, however, it was criticized as ineffective or destabilizing. While specific regions and mission types were previously researched, a comprehensive analysis of all EU crisis management operatio
