I ett villaområde finns många olika slags gränser mellan ”mitt” och ”ditt”. I den här artikeln vill vi med utgångspunkt i villaträdgården diskutera exempel på hur sådana gränser tänjs och utmanas. En aspekt är att trädgårdens växter och djur överskrider tomtgränser. Växter vandrar exempelvis ibland in av sig själva, som välkomna tillskott, eller oönskade ogräs. Här är det särskilt intressant att r
Vad innebär det egentligen att vara akademiker i vår tid? Vilka är förväntningarna på oss som universitetslärare och forskare och hur lever vi upp till dem? Vad utmärker en skicklig akademiker och vilka är våra skyldigheter som lärare och kolleger? Går det att kombinera forskning och undervisning på ett fruktbart sätt? Och hur når vi ut med vår forskning? Ska vi publicera oss i tidskrifter eller g
”Hur klarar man livet som idealist och självförsörjande småbonde i det moderna och entreprenördrivna Sverige” undrar en av Sydsvenskans journalister i samband med att han kommit över en ny utgåva av Bondepraktikan samtidigt som tv-programmet Mandelmanns Gård har nypremiär (14/1 2018). Utgångspunkten för denna presentation är en studie om landsbygdens livsstilsentreprenörer, dvs. småskalig verksamh
Due to the disruptive role of the Bitcoin in the financial sector, both scholars and practitioners are increasingly wondering whether it is possible to replicate the impact of the Blockchain technology in the supply chain context. As a distributed ledger technology characterized by the decentralized consensus, Blockchain is touted by many as the proper platform to collect all the information about
Extracellular electron transfer (EET) in microbial cells is essential for certain biotechnological applications and contributes to the biogeochemical cycling of elements and syntrophic microbial metabolism in complex natural environments. The Gram-positive lactic acid bacterium Enterococcus faecalis, an opportunistic human pathogen, is shown to be able to transfer electrons generated in fermentati
Return to Kashgar – the Jarring Collection of Uyghur Manuscripts Kashgar was a major crossroads for trade and culture along the Eurasian Silk Route for thousands of years, a place where Turkic, Persian, Arab, Chinese and other groups interacted. The Lund University Library is privileged to hold some 600 handwritten books from the sixteenth to the twentieth centuries from cities in this region like
Climate change projections show that temperature and precipitation increases can alter the exchange of greenhouse gases between the atmosphere and high latitude landscapes, including their freshwaters. Dissolved organic carbon (DOC) plays an important role in greenhouse gas emissions, but the impact of catchment productivity on DOC release to subarctic waters remains poorly known, especially at re
Background: Cadmium bioaccumulates in the body and causes several adverse health effects. Understanding the primary sources of exposure is critical in order to implement effective prevention measures. Methods: We included 454 adults enrolled in the Florence cohort of the European Prospective Investigation into Cancer and Nutrition (EPIC) during 1992–98. At enrolment, information was collected on d
Groundwater quality and quantity are two major challenges in arid and semi-arid regions, due to their critical roles in sustainable agricultural development. Irrigated lands are spread all over Urmia Lake's surrounding plains in Iran. Due to the risk of saltwater intrusion as a result of over-exploitation from groundwater resources, it is important to monitor the groundwater quality and quantity t
Thermal properties of pure tungsten, irradiated in the Swiss neutron spallation source at the Paul Scherrer Institut, have been studied in the temperature range 25–500 °C. Disk-shaped specimens were prepared from a tungsten sheet which was irradiated with high energy protons and spallation neutrons. The specimens tested in this work received total damages of maximum 3.9 and 5.8 dpa at average irra
The concept of circular business models has been identified as an important enabler for companies moving towards circular practices. Circular business models help to prolong lifetimes of products and parts through successive cycles of reuse, repair, remanufacturing and closing material loops. To realise economic viability and reductions in environmental impacts from innovating towards a circular b
Climate change can lead to an increased frequency of extreme weather events, which may induce a decline in tree vitality, rendering the forest more vulnerable to other stress factors. In this study we used the ecosystem model LPJ-GUESS to compare the NPP of boreal conifers on till soil and sandy soil, simulating the growth of Norway spruce during the 21st century using climate model projections co
A tiered process was developed to assess the transformation, CO2 formation and uptake of four organic micropollutants by carrier-attached microorganisms from two municipal wastewater treatment plants. At the first tier, primary transformation of ibuprofen, naproxen, diclofenac, and mecoprop by carrier-attached microorganisms was shown by the dissipation of the target compounds and the formation of
This paper reports on studies of multiple-injection strategies of gaseous fuel in a model combustion chamber and the role of jet-jet interactions on the mixing processes in the chamber using large-eddy simulation (LES). A high-pressure non-reacting gas flow injected through a jet with a nozzle diameter of 1.35 mm into a quiescent inert air environment is considered. First, we validate the method a
Background: The characteristics and prognosis of healthy obesity (HO) still remain unclear. We aimed to examine the characteristics of healthy severe obesity (HSO), defined by a novel approach, with a focus on self-reported physical activity (PA) and a genetic risk score for type 2 diabetes (GRS DM2). Methods: A cross-sectional analysis was carried out in a subsample of severly obese subjects (BMI
