Functional aspects of cellobiose dehydrogenase Applications for biosensor development

Electrochemcial investigations were conducted for elucidating and understanding the relation between the various electron transfer processes occurring in cellobiose dehydrogenase (CDH) bound to an electrode surface. Substrate inhibition caused by cellobiose was proven to act in competition with the electron transfer to a two-electron acceptor and under a partial inhibition mechanism for the in

Intergenerational Transmission of Human Capital: Is It a One-Way Street?

Studies on the intergenerational transmission of human capital usually assume a one-way spillover from parents to children. But what if children also affect their parents’ human capital? Using exogenous variation in education, arising from a Swedish compulsory schooling reform in the 1950s and 1960s, we address this question by studying the causal effect of children’s schooling on their parents’ l

Myth, Identity, and Conflict : A Comparative Analysis of Romanian and Serbian Textbooks

Abstract in UndeterminedMyth, Identity, and Conflict: A Comparative Analysis of Romanian and Serbian Textbooks, by Anamaria Dutceac Segesten, is an examination of how history and politics became entangled in Romania and Serbia. In it, Segesten asks questions like: Is myth present in the history textbooks of Romania and Serbia? If so, are there differences in the ways these myths define the in-grou

Investigation of ionization-induced electron injection in a wakefield driven by laser inside a gas cell

Ionization-induced electron injection was investigated experimentally by focusing a driving laser pulse with a maximum normalized potential of 1.2 at different positions along the plasma density profile inside a gas cell, filled with a gas mixture composed of 99%H2+1%N2. Changing the laser focus position relative to the gas cell entrance controls the accelerated electron bunch properties, such as

Which agricultural management interventions are most influential on soil organic carbon (using time series data)?

Background: Loss of soil organic carbon (SOC) from agricultural land is identified as one of the major threats to soils, as it influences both fertility and the production of ecosystem services from agriculture. Losses of SOC across regions are often determined by monitoring in different land use systems. Results from agricultural field experiments can reveal increasing SOC stocks after implementa

Utrymning och tekniska installationer i vägtunnlar med dubbelriktad trafik

The report provides an overview of human behaviour in tunnel fires in single tube road tunnels. The behaviour is linked to the concept of a behaviour sequences presented by Canter et al. (1980). The main focus has been to present relevant research and findings provided in accident investigation reports mainly for long and steep sub-sea tunnels designed according to the self-rescue principle. Resea

How does tillage intensity affect soil organic carbon? A systematic review protocol

Background: Soils contain the greatest terrestrial carbon (C) pool on the planet. Since approximately 12 % of soil C is held in cultivated soils, management of these agricultural areas has a huge potential to affect global carbon cycling; acting sometimes as a sink but also as a source. Tillage is one of the most important agricultural practices for soil management and has been traditionally under

Climate, CO2 and human population impacts on global wildfire emissions

Wildfires are by far the largest contributor to global biomass burning and constitute a large global source of atmospheric traces gases and aerosols. Such emissions have a considerable impact on air quality and constitute a major health hazard. Biomass burning also influences the radiative balance of the atmosphere and is thus not only of societal, but also of significant scientific interest. Ther

Scale-invariant nonlinear optics in gases

Nonlinear optical methods have become ubiquitous in many scientific areas, from fundamental studies of timeresolved electron dynamics to microscopy and spectroscopy applications. They are, however, often limited to a certain range of parameters such as pulse energy and average power. Restrictions arise from, for example, the required field intensity as well as from parasitic nonlinear effects and

Prioritization guidelines for green food packaging development

Purpose: Current literature emphasizes using a holistic perspective on green packaging development (GPD) as an important strategy for reducing the environmental impact of products’ supply chain (SC). In practice, however, it can be difficult for packaging developers to strike a balance between all the different environmental requirements on packaging, and trade-offs are common. Life cycle assessme
