In 2015 the Airbnb headquarters in San Francisco were occupied by housing activists who protested against the city's increasing housing prises. They pointed out how Airbnb's short-term rentals in the city lead to gentrification and to local residents being displaced from their homes. As a result, many people become homeless and can not return to the city again. Airbnb is no longer the sharing-econ

A central concept raised by the climate justice movement is climate debt. Here, the claims and warrants of the movement support for climate debt is identified through an argumentation analysis of their central manifestos. It is found that the climate debt claim is understood as primarily restorative, in the sense that the environmental space of the developing countries must be returned, “decolonizA central concept raised by the climate justice movement is climate debt.

Ekosystemen i vår värld förändras av naturliga krafter, som i sin tur påverkas av mänskliga aktiviteter. För att förstå och beräkna effekterna av klimatförändringar och mänsklig förvaltning på våra ekosystem har behovet av instrument för att övervaka och förutsäga jordsystemet ökat. Dynamiska globala vegetations modeller är matematiska modeller som tillåter en processbaserad beskrivning av växtsamDynamic global vegetation models are mathematical models that provide a bottom-up description of plant communities. They explicitly model physiological and population-level processes such as growth, photosynthesis, carbon allocation, regeneration and mortality.However, there are a number of challenges to meet in the context of mechanistic vegetation models which can be extrapolated to new environm

Tissue regeneration requires dynamic cellular adaptation to the wound environment. It is currently unclear how this is orchestrated at the cellular level and how cell fate is affected by severe tissue damage. Here we dissect cell fate transitions during colonic regeneration in a mouse dextran sulfate sodium (DSS) colitis model, and we demonstrate that the epithelium is transiently reprogrammed int

Presentation av Lunds Universitets Historiska Museum för utställningen "Mellan liv och död" på Lunds Konsthall 31 augusti - 27 oktober 2002. En bok med samma titel publicerades i samband med utställningen, där tolv arkiv och museer i Lund berättar om sina unika verksamheter i samband med en då pågående utredning vid Lunds universitet om fyra museers framtid : Antikmuseet, Botaniska museet, Histori

För varje typ av djur finns en optimal storlek, men större är ofta bättre. För 300 miljoner år sedan var jättelika drakeflugor de största insekterna någonsin. Högre atmosfäriska syrekoncentrationer tros ha tillåtit dem att både flyga och utvecklas till jättar. Men idag är de största sländorna inte större än en mänsklig hand och tar decennier att utvecklas till vuxna. Men varför blir kråkmått ellerBody size and body temperature are the two most important traits in biology. In this thesis I show how these twovariables have shaped the evolution of insects over the last 300 million years. These variables are so important infact that three rules have been developed to summarize their effects: (1) bigger is better, (2) hotter makes yousmaller, and (3) hotter is better.Using primarily dragonflies

Aim: To investigate whether gut maturation could be induced precociously in an athymic T-cell deficient neonatal rat model. Methods: Fourteen day-old athymic (nude) rats (NIH-Foxn 1rnu) were gavaged with either phytohaemagglutinin - a lectin from red kidney beans (PHA); trypsin - a protease (Prot); or water - vehicle (control) as a single dose on one day or once a day for 3-day. The nude rats were

Objective: A model for simulating multi-lead ECG signals during paroxysmal atrial fibrillation (AF) is proposed. Significance: The model is of particular significance when evaluating detection performance in the presence of brief AF episodes, especially since annotated databases with such episodes are lacking. Approach: The proposed model accounts for important characteristics such as switching be

Finds and observations of the Silvery Leafcutter Bee Megachile leachellaNT Curtis in Åhus, the Swedish province of Scania, are reported, with observations of some other bee species. The Åhus area is one of the most important bee diversity areas in Sweden.The Large Yellow-Face Bee Hylaeus signatusNT (Panzer) (Hymenoptera: Colletidae) found in the Botanical Garden of Lund.

A first find and a few subsequent observations of the oligolectic Large Yellow-Face Bee Hylaeus signatusNT (Panzer) were made during the second half of August in the Botanical Garden of Lund, province of Scania, Southern Sweden. About a dozen of specimens were attracted to a stand of Reseda luteola, one of its primary pollen sources. This bee is one of several newcomers among solitary bees in SwedA first find and a few subsequent observations of the oligolectic Large Yellow-Face Bee Hylaeus signatusNT (Panzer) were made during the second half of August in the Botanical Garden of Lund, province of Scania, Southern Sweden.
