Swedish alpine and subarctic areas undergo rapid transitions due to climate change, especially in relatively humid areas where the forest vegetation is expanding. It has been suggested that lakes in these areas are in transition from clearwater into brownwater state, because of the humus layer building up in surrounding soils, with negative consequences, e.g., for the biomass production of zooplan

Planktonic community respiration is an important carbon cycling process, typically quantified by converting measured values of dissolved oxygen consumption rates into carbondioxide production rates using a respiratory quotient of 1 (RQ = carbondioxide per oxygen by moles). However, the true variability in planktonic RQs between different aquatic ecosystems is poorly understood. We conducted in sit

The stable carbon isotope ratio (δ13C) is a key tool in tracing the source of carbon within and across ecosystems. In isotope mixing models dissolved organic carbon (DOC) from terrestrial sources is often assigned a fixed δ13C of roughly -28‰ to -27‰ in C3 plant-dominated areas. However, the claim of a uniform δ13C distribution for terrestrial DOC sources of different reactivity has seldom been te

What explains subnational policy choices over tax cut after decentralization? We test two different explanations in the context of the 2002 tax reform in Russia. A popular strand of literature suggests that decentralization induces more regional competition over investment, motivating subnational tax cuts. A second body of literature suggests that personal business interests of regional governors

Background Pancreatic cancer has a dismal prognosis and clinical protocols are still lacking predictive biomarkers. RNA-binding motif protein 3 (RBM3) has emerged as a promising biomarker in several solid cancers, including pancreatic cancer.. High RBM3 expression in human tumors has been associated with good response to chemotherapy, as well as to confer increased chemosensitivity in vitro. The

The burden of mental disorders continues to grow and is now a leading cause of disability worldwide. The prevalence of mental disorders is unequal between population subgroups, and these disorders are associated with unfavourable consequences in social and economic conditions, health and survival. However, how the negative effects of mental disorders are distributed among population subgroups is lThe burden of mental disorders continues to grow and is now a leading cause of disability worldwide.

BackgroundSubstandard and falsified medical products are a public health threat, primarily associated with low- and middle-income countries. Today, the phenomenon also exists in high-income countries. Increased Internet access has opened a global market. Self-diagnosis and self-prescription have boosted the market for unregulated websites with access to falsified medicines.AimTo describe the state

Infrared light is the most common choice for illumination of the eye in current eye trackers, usually produced via IR light-emitting diodes (LEDs). This chapter provides an overview of the potential hazards of over-exposure to infrared light, the safety standards currently in place, configurations and lighting conditions employed by various eye tracking systems, the basics of measurement of IR lig
