Nonequilibrium dynamics of mixtures of active and passive colloidal particles

We develop a mesoscopic field theory for the collective nonequilibrium dynamics of multicomponent mixtures of interacting active (i.e., motile) and passive (i.e., nonmotile) colloidal particles with isometric shape in two spatial dimensions. By a stability analysis of the field theory, we obtain equations for the spinodal that describes the onset of a motility-induced instability leading to cluste

Investigating the space for research and learning within doctoral education in medicine

Doctoral education in medicine, engineering, technology and science (METS) is in many ways different from doctoral education in the humanities or social sciences. In the METS disciplines, typically, students and supervisors work and publish together within the supervisors’ research projects. The projects are usually financed by the supervisors’ research grants and their success, in terms of high q

Global consequences of afforestation and bioenergy cultivation on ecosystem service indicators

Land management for carbon storage is discussed as being indispensable for climate change mitigation because of its large potential to remove carbon dioxide from the atmosphere, and to avoid further emissions from deforestation. However, the acceptance and feasibility of land-based mitigation projects depends on potential side effects on other important ecosystem functions and their services. Here

Introduction : Combinatorial Knowledge Bases, Regional Innovation, and Development Dynamics

The special issue zooms in on knowledge dynamics that drive innovation processes and new path development in different regional and sectoral contexts. This investigation rests on the differentiated knowledge base approach, which offers a clear distinction between analytical, synthetic and symbolic types of knowledge and deep insights into their idiosyncrasies. The introduction frames knowledge bas

Violaxanthin de-epoxidase and its closest relative: identification and characterization

Växter behöver ljus för att växa. Ljuset omvandlas till kemisk energi genom fotosyntes i växtens blad. Den kemiska energin kan sedan användas av växten. Ljusabsorptionen i växter har en begränsning. Alltför mycket ljus kommer att orsaka bildning av högenergimolekyler som är skadliga för växterna. Därför måste växter justera mängden ljus som tas upp. Ljuset i miljön förändras ständigt och exponerinLight is essential for plants and algae to process photosynthesis. However, excess of light will cause damage to the organism. A process called non-photochemical quenching (NPQ) is an important way for these organisms to protect themselves from photo oxidative damage. The NPQ process is depend on the xanthophyll cycle in thylakoids, which is controlled by the Violaxanthin de-epoxidase (VDE) and ze

The Iron Age Horse

The Sösdala find with its exquisite horse equipment is spectacular and testifies to the prominent role of the horse in Iron Age society. Although the remains of the horses themselves are absent, information about the animal's physical characteristics can be found in related finds from elsewhere in Scandinavia. It is possible to infer that the horses do not seem to have expressed much phenotypic va

Corruption, Social Norms and Everyday Life in Uzbekistan

In this chapter, we explore the multifaceted role, logic and morality of informal transactions in order to better understand the socio-legal context informing the meaning of corruption. Our aim is to show how informal or illegal practices (‘corruption’ from a legal standpoint) not only mirror kleptocracy, individual greed, economic interests or survival strategies, but also re ect social norms gen

Household installation of solar panels – Motives and barriers in a 10-year perspective

This article compares what homeowners identified as motives and barriers for installing photovoltaic panels in Sweden in 2008–2009 and in 2014–2016. Earlier research has provided snapshots of existing barriers and motives, but not analyzed changes over time, as is done here. Between 2008 and 2014, the PV market in Sweden changed profoundly, with the introduction of subsidies and changes in rules,

Olfactory language and abstraction across cultures

Olfaction presents a particularly interesting arena to explore abstraction in language. Like other abstract domains, such as time, odours can be difficult to conceptualize. An odour cannot be seen or held, it can be difficult to locate in space, and for most people odours are difficult to verbalize. On the other hand, odours give rise to primary sensory experiences. Every time we inhale we are usi

Från kraftprov till systembejakande talmagi : Jubileer i antiken

This paper highlights and discusses the concept of the jubilee in Antiquity through a series of case studies. The ancient jubilee is defined as a temporally based, and often recurring, communal celebration, which encompasses longer time spans, from ten to a thousand years. The examples elaborated on by the present authors are: the Jewish Yovel, the Egyptian Heb-Sed and the Roman decennalia (Leande

Combining modern plant breeding and enzyme technology to obtain highly enriched erucic acid from Crambe oil

BackgroundFatty acids from vegetable oils are useful building blocks for industrial materials. The purpose of this work was to prepare erucic acid with high purity from a vegetable oil. High purity erucic acid is used for the production of erucamide with applications in plastics manufacturing. A newly developed transgenic Crambe line produces seed oil with 68 % erucic acid compared to 53 % in the
