Poly(arylene piperidinium)s – a new class of anion-exchange membranes

Anion exchange membranes (AEMs) are crucial components of various electrochemical devices. To function well they require both high chemical and mechanical robustness, as well as a sufficient hydroxide conductivity. However, due to the aggressive nature of the hydroxide ion, which causes polymer degradation, the applicability of AEMs is so far limited.1-2 As a consequence, a lot of effort is presen

Islet glucan-1,4-alpha-glucosidase : differential influence on insulin secretion induced by glucose and isobutylmethylxanthine in mice

In previous in-vivo studies we have presented indirect evidence for the involvement of islet acid glucan-1,4-alpha-glucosidase (acid amyloglucosidase), a lysosomal glycogen-hydrolysing enzyme, in certain insulin secretory processes. In the present combined in-vitro and in-vivo investigation, we studied whether differential changes in islet acid amyloglucosidase activity were related to the insulin

Machinability and manufacturing cost in low-lead brass

Today, commercially used brasses commonly contain 2 to 4 wt% lead. As the availability of low-lead and lead-free brass increases, there are environmental incentives for investigating the consequences of replacing the lead-containing brasses with lead-free equivalents. Generally, lead-free brass is expected to have a lower machinability than its lead-alloyed counterpart, implying a higher manufactu

Stock market dependence and product market linkages

We study the implications of interfirm product market linkages for dependence among the daily stock returns of US publicly traded firms using a spatial econometric regression. The effects of rivals and major customers change with various characteristics related to the product market network. We find that the competitive effect dominates the contagion effect for firms competing in highly concentrat

Legitimacy and Accountability in Polycentric Climate Governance

Polycentricity is characterised by institutional fragmentation as well as a new quality of interdependence where non-state and state actors are both regulators and regulated. This complexity raises new questions for democratic governance beyond the nation state. Against this backdrop, we first develop the argument that certain legitimacy and accountability challenges are inherent to polycentricity

Nutrition and colorectal cancer - The role of BMI, sex, biomarkers and dietary index

Colorectal cancer (CRC) is one of the most common forms of cancer. The cause of CRC is multifactorial, and lifestyle factors are thought to be a major contributor to the development of CRC. It can be hypothesised that the association between food intake and the risk of developing CRC depends not only on the food consumed, but what it is consumed in combination with. The associations between food a

Visual configuration of two species of Falconidae with different foraging ecologies

Significant interspecific differences in avian vision occur, even in congeneric species, and these have been correlated with differences in the perceptual challenges associated with foraging. Although diurnal raptors are assumed to be mainly visually guided in their foraging, they differ markedly in their foraging tactics and this may result in different visual demands. Among the Falconidae (Falco

Botanical evidence of malt for beer production in fifth–seventh Century Uppåkra, Sweden

The excavation of a low-temperature kiln structure at an affluent Iron Age regional center, Uppåkra, located in southern Sweden, revealed from archeobotanical samples and its context evidence of malting in the process to make beer. Carbonized germinated hulled barley grain (Hordeum vulgare) was recovered from the kiln structure itself and from the surrounding occupationalsurface.

Recognizing Carbon Forestry’s Uneven Geography: A Response to Purdon and the Structure-Agency Dichotomy That Never Was

We here respond to the critique by Purdon of an article on carbon forestry that we published in this journal last year (Carton and Andersson). While we welcome critical engagements with our work, Purdon’s argument is wide of the mark and appears based largely on misconceptions regarding our theoretical entry point and empirical findings. Underlying this are fundamental disagreements about the natu
