Gudar och människor bland texter och paratexter : Om varför Gamla testamentet inte har några författare

It is a wellknown fact that the books of the Hebrew Bible are, to a great extent, anonymous and that the individuals long identified as their authors (Moses, Isaiah, David, Solomon, and so on) are not the ones who have penned them. How, then, should the few paratexts that do, in fact, relate texts explicitly to named individuals be understood? In this article, I argue that such a question is essen

Gene-environment interactions and metal toxicity

Humans are exposed to various metals through many different routes and each person’s genetic background contributes to their susceptibility to metal toxicity. In addition, recent evidence points to a role for the genetics of the human microbiome in metal uptake and toxicity. DNA sequence variation in genes that regulate metal toxicokinetics and toxicodynamics influences metal accumulation and rete

Ecological impact of introduced and native crayfish on freshwater communities : European perspectives

Interest in the culture of freshwater crayfish throughout Europe has increased during the last few decades. However, the effects of both introduced and native crayfish species on the structure and diversity of freshwater communities has received little attention. In this paper, I review the impact of crayfish on macrophytes, algae, invertebrates, amphibians and fish; also I compare the impact of i

Rheological modification of partially oxidised cellulose nanofibril gels with inorganic clays

This study aimed to quantify the influence of clays and partially oxidised cellulose nanofibrils (OCNF) on gelation as well as characterise their physical and chemical interactions. Mixtures of Laponite and montmorillonite clays with OCNF form shear-thinning gels that are more viscous across the entire shear range than OCNF on its own. Viscosity and other rheological properties can be fine-tuned u

Thermal resilience of ensilicated lysozyme via calorimetric and in vivo analysis

Ensilication is a novel method of protein thermal stabilisation using silica. It uses a modified sol-gel process which tailor fits a protective silica shell around the solvent accessible protein surface. This, electrostatically attached, shell has been found to protect the protein against thermal influences and retains its native structure and function after release. Here, we report the calorimetr

Antagonistic mixing in micelles of amphiphilic polyoxometalates and hexaethylene glycol monododecyl ether

Hypothesis: Polyoxometalates (POMs) are metal oxygen clusters with a range of interesting magnetic and catalytic properties. POMs with attached hydrocarbon chains show amphiphilic behaviour so we hypothesised that mixtures of a nonionic surfactant and anionic surfactants with a polyoxometalate cluster as headgroup would form mixed micelles, giving control of the POM density in the micelle, and whi

Environmental Factors Affecting Feather Taphonomy

The exceptional preservation of feathers in the fossil record has led to a better understanding of both phylogeny and evolution. Here we address factors that may have contributed to the preservation of feathers in ancient organisms using experimental taphonomy. We show that the atmospheres of the Mesozoic, known to be elevated in both CO2 and with temperatures above present levels, may have contri
