Förlust av biologisk mångfald och klimatkrisen är nära sammankopplade. Ett varmare klimat påverkar exempelvis människor, vilda organismer och hela ekosystem samtidigt som minskad biologisk mångfald förvärrar effekterna av klimatförändringarna. Innovativ forskning ska begränsa skadeeffekterna av dessa sammanvävda kriser. Forskare vid Lunds universitet undersöker de komplexa samband som finns mellan

Global land acquisitions, often dubbed 'land grabbing' are increasingly becoming drivers of land change. We use the tools of network science to describe the connectivity of the global acquisition system. We find that 126 countries participate in this form of global land trade. Importers are concentrated in the Global North, the emerging economies of Asia, and the Middle East, while exporters are c

Den fackliga organisationsgraden är fortfarande mycket hög i Sverige. Sedan de svenska a-kasseavgifterna höjts kraftigt 2007 inträffade ett fackligt medlemsras utan motsvarighet i Sveriges moderna historia. Arbetsgivarnas organisationsgrad (definierad som andelen löntagare i företag och förvaltningar som tillhör en arbetsgivarorganisation) är numera betydligt högre än löntagarnas. Artikeln redovis

Digital controllers are traditionally implemented using periodic sampling, computation, and actuation events. As more control systems are implemented to share limited network and CPU bandwidth with other tasks, it is becoming increasingly attractive to use some form of event-based control instead, where precious events are used only when needed. Forms of event-based control have been used in prac

Integration of III-V semiconductors on Si substrates allows for the realization of high-performance, low power III-V electronics on the Si-platform. In this work, we demonstrate the implementation of single balanced down-conversion mixer circuits, fabricated using vertically aligned InAs nanowire devices on Si. A thin, highly doped InAs buffer layer has been introduced to reduce the access resista

We present comprehensive results on continuous atmospheric cluster and particle measurements in the size range similar to 1-42 nm within the European Integrated project on Aerosol Cloud Climate and Air Quality interactions (EUCAARI) project. We focused on characterizing the spatial and temporal variation of new particle formation events and relevant particle formation parameters across Europe. Dif

Study Design. This article describes the development of a musculoskeletal model of the human lumbar spine with focus on back muscles. It includes data from literature in a structured form. Objective. To review the anatomy and biomechanics of the back muscles related to the lumbar spine with relevance for biomechanical modeling. Summary of Background Data. To reduce complexity, muscle units have be

Background/Aims: Large epidemiological prospective studies represent an important opportunity for investigating risk factors for rare diseases such as Parkinson's disease (PD). Here we describe the procedures we used for ascertaining PD cases in the EPIC (European Prospective Investigation into Cancer and Nutrition) study. Methods: The following three-phase procedure was used: (1) elaboration of a

This project, aimed to the digital documentation of archaeological sites, artifacts and cultural relics of the Western Han Dynasty, started in 2008. The anticipated outcome will be the creation of a virtual museum, based on collaborative environments, dedicated to the Western Han Dynasty and able to integrate new archaeological datasets coming from fieldwork activities (most part of them unpublish

Selective isolation of lactate dehydrogenase (LDH) from porcine muscle extract was studied using foam generated from the vigorous stirring of a non-ionic surfactant, Triton X-114 derivatized with Cibacron blue. The cloud point of the surfactant-dye conjugate was higher than that of the native Triton X-114, and also the foam prepared from the affinity surfactant was more rigid taking a longer time

Biomarker levels in cerebrospinal fluid (CSF) may serve as surrogate markers for treatment efficacy in clinical trials of disease-modifying drugs against Alzheimer's disease (AD). A prerequisite, however, is that the marker is sufficiently stable over time in individual patients. Here, we tested the stability of the three established CSF biomarkers for AD, total tau (T-tau), tau phosphorylated at

The aim of this study was to characterize the reversible cerebral uptake of morphine in the pig by measuring the changing arterio-venous plasma concentration gradient over the brain. Seven pigs were anaesthetized by continuous infusions of ketamine and pancuronium and ventilated with oxygen in nitrous oxide. During and after 5-min intravenous infusions of morphine hydrochloride, blood samples were

BACKGROUND: Total heart volume variation (THVV) and center of volume variation (COVV) likely affects the efficiency of cardiac pumping, but no study has determined COVV of the heart throughout the cardiac cycle or the effect of surgery on THVV in adults. Therefore, the purposes of this study were to determine COVV in healthy adults and patients with cardiac failure due to ischemic heart disease (I

Energiförbrukningen i elektronikprodukter minskar samtidigt som prestandan för solceller hela tiden ökar. Nya solcellstyper med lägre priser skapar nya möjligheter för använding även i små elektronikprodukter. Att samla energi från omgivningen, t.ex. från ljuset i ett rum, och använda det för att driva små elektronikprodukter kallas i ett vidare begrepp för ”energy harvesting” (SV: energiskördningThe power consumption of electronic devices is decreasing at the same time as the performance of solar cells is increasing. Solar cells based on new technologies with lower costs are becoming commercially available, creating new opportunities for use in small electronic products. The concept of capturing ambient energy, such as light, and using it to power small electronic devices is known as ener

Denna uppsats analyserar och jämför legal reglering av motorfordons ansvar vid uppkommen skada i Sverige och Norge, med fokus på rekvisiten ”skada i följd av trafik” i Sverige respektive skade som motorvogn gjer i Norge. Dessa rekvisit är de som definierar omfånget av fordons ansvar vid uppkommen skada och därmed de skador som ska ersättas av fordonets trafikförsäkring. Uppsatsen visar att syftThis essay analyzes and compares the legal regulation of motor liability insurance in Sweden and Norway with emphasis on the primary legal requirements for the Laws to apply, namely “skada till följd av trafik” (damage as a result of motor vehicle traffic) in Sweden and “skade som motorvogn gjer” (damage caused by motor vehicle) in Norway. These are the primary requirements that define the scope

As climate change continues to escalate, the need for drastic changes is urgent. The world has agreed on a limit to global warming, and all countries are aware of the problem. The theory behind the Environmental Kuznets Curve is based on an inverted relationship between emissions and environmental impact and GDP growth. It could easily be interpreted as an easy way out of, which means that if a co
