Cyanobakterier är urgamla prokaryoter, som finns i en mängd olika livsmiljöer över hela världen. Deras förmåga att utföra fotosyntes (det vill säga att använda solljus, vatten och koldioxid för att producera syre- och kolhydrater) gör dem till viktiga primära producenter, och tillsammans med andra växtplankton utgör de basen för akvatiska näringsvävar.Vid optimala tillväxtförhållandena kan populatCyanobacterial blooms are increasing in occurrence and frequency world-wide, mainly due to eutrophication and increased water temperatures. In freshwater, Microcystis is one of the most common bloom-forming genera, renowned for producing the toxin microcystin which is harmful to humans and other mammals. The ability of Microcystis strains to produce microcystins is largely due to the presence or a

During the past years, activist movements have increasingly turned to social media to raise awareness and critically discuss current development and future scenarios. As a contribution to the discussion of new social movements and activism in the digital age, this study aims to explore and critically discuss how environmental risks and crisis are visually communicated in activism campaigns on Inst

This paper presents a norm-critical aspect on universal design and waste in a collaborative research project with the objective of creating more inclusive solutions for waste systems. The overall ambition of this study is to build on knowledge of the role of design as an activity of shaping the human surroundings and as an expression of the culture to which it belongs.

Mikroskopi är idag ett fundamentalt verktyg inom forskning, där det tillåter oss att skåda in och utforska våra prover i hög detalj. Mycket utav utvecklingen av nya mikroskopimetoder har strävat efter att öka den detaljnivå vi kan uppnå. Samtidigt har utvecklingen inom hårdvara, med tillgång till bättre och mer kraftfulla instrument, lett till utveckligen av metoder där fokuset är att studera en h

With the risk of climate breakdown, pressure is increasing for all sectors of the economy to break with fossil fuel dependence and reduce greenhouse gas emissions. In this context, the chemical industry requires more focused attention as it uses more fossil-fuel based energy than any other industry and the production of chemicals is associated with very large emissions. Beyond the climate crisis,

Despite the glimmer of hope provided by the discovery and commercialization of bone morphogenetic protein-2 (BMP-2) as a bone graft substitute, side effects related to the use of supraphysiological doses have hindered its clinical usage. In this study, we compared the osteoinductive potential of BMP-2 homodimer with a heterodimer of BMP-2/7, both delivered via a collagen-hydroxyapatite (CHA) scaff

We are on a hunt for the invisible in this second episode of the third season of The Meridian. Ruth Pöttgen is a senior lecturer at the Department of Physics where she is studying fundamental particles. She is especially interested in finding that mysterious and elusive Dark Matter particle.In this third season we are also including some Cosmic Curiosities. These are some ideas, events or trivia f

The case presents Sardex, a local complementary currency in the Mediterranean island of Sardinia designed to alleviate the economic hardships brought by the economic crisis of 2008.The reader gets an insight into the economic contexts of these currencies, the functioning of one of its most common designs (mutual credit systems or LETS), as well as the work of embedding these local currencies into

Judith Korth joins the podcast this week and tell us about how she found her way into astronomy research, how she ended up here at Lund University and how she now studies distant worlds far beyond our own Solar System.In this third season we are also including some Cosmic Curiosities. These are some ideas, events or trivia from astronomic history that Ross, Victor and Lucian feel are worth bringin

Astronomers, such as Nic and Rebecca, are not the only ones orienting themselves using the stars. Animals, big and small, also navigate by starlight. In this last episode of the third season we invited Prof. Marie Dacke from the Department of Biology over to tell us about her research on the subject.In this third season we are also including some Cosmic Curiosities. These are some ideas, events or

Joining Nic and Rebecca in this first episode of the third season of The Meridian is none other than NASA astronaut Jim Pawelczyk, professor at Penn State University in Kinesiology and Physiology, who looks into how the human body adapts when in space.In this third season we are also including some Cosmic Curiosities. These are some ideas, events or trivia from astronomic history that Ross, Victor

We investigate the classicality of linear dipolar droplet arrays through a normal mode analysis of the dynamical properties in comparison to the supersolid regime. The vibrational patterns of isolated-droplet crystals that time-evolve after a small initial kick closely follow the properties of a linear droplet chain. For larger kick velocities, however, droplets may coalesce and separate again, sh

Den här antologin innehåller tolv examensarbeten skrivna av tretton folkhögskollärare examinerade från Linköpings universitet våren 2021. På Linköpings universitet erbjuds en lärarutbildning specifikt för folkhögskolan. Studenterna kombinerar teoretiska studier med praktik ute i verkligheten, och deras examensarbete syftar till att skapa eller analysera didaktiska innovationer för folkhögskolorna.

Urbanization is not only a concentration of humans in city areas but also, the consumption and production activities that are comprised in urban space. In this sense, goods and services are developed through the urban economic actors, through labor, economic diversity, and prosperity. This article reviews the relationship between urban economics and tradesmen & craftsmen (TC). The focus is on
