Development of a bioanalytical test battery for water quality monitoring : Fingerprinting identified micropollutants and their contribution to effects in surface water

Surface waters can contain a diverse range of organic pollutants, including pesticides, pharmaceuticals and industrial compounds. While bioassays have been used for water quality monitoring, there is limited knowledge regarding the effects of individual micropollutants and their relationship to the overall mixture effect in water samples. In this study, a battery of in vitro bioassays based on hum

Linking in Vitro Effects and Detected Organic Micropollutants in Surface Water Using Mixture-Toxicity Modeling

Surface water can contain countless organic micropollutants, and targeted chemical analysis alone may only detect a small fraction of the chemicals present. Consequently, bioanalytical tools can be applied complementary to chemical analysis to detect the effects of complex chemical mixtures. In this study, bioassays indicative of activation of the aryl hydrocarbon receptor (AhR), activation of the

An econometric analysis of the macroeconomic determinants of carbon dioxide emissions in Nigeria

This study examined an econometric analysis of the macroeconomic determinants of carbon dioxide (CO2) emission in Nigeria, covering the periods between 1981 and 2016, employing both linear and non-linear Autoregressive Distributed Lag (ARDL & NARDL) models. The time series data used were sourced from the database of the World Bank Development Indicators, 2016 and Central Bank of Nigeria Statis

ERP studies of visual and auditory processing of negated sentences

In two event-related potential studies, we investigated the processing of sentences with prefixal negation (unauthorized), sentential negation (not authorized) and no negation (authorized). We asked whether prefixal and sentential negation resulted in delayed processing. In Experiment 1, sentences such as “The White House announced that the new Obama biography was authorized/unauthorized/not autho

Heat transfer and flame stabilization of laminar premixed flames anchored to a heat-flux burner

Measurement of the burning velocity of unstretched laminar hydrogen/air premixed flames suffers from large uncertainties owing to the highly diffusive nature of hydrogen that can give rise to flame instability. This paper reports on a numerical study of the structures and stability of laminar premixed CH4/O2/CO2 flames and H2/O2/N2 flames anchored to a heat-flux burner using a high-order numerical

The Singular Event of Jesus' Death in Early Christianity

This article looks to the philosophy of Gilles Deleuze in order to theorize the crucifixion of Jesus as event in early Christian literature. A Deleuzian view on the event is primarily articulated with the distinction between a sequential and a serial understanding of happenings, where the latter forms the basis for singular events. It is argued that Jesus' death is best considered a singular event

En kopp kaffe och Marx, tack!

Bokcaféerna spelade en avgörande roll inom den västeuropeiska vänsterns tryck- och mediekultur under 1970-talet. Även i Sverige gjorde bokcaféerna omfattande avtryck inom kultur- och samhällslivet, till exempel genom att etablera den politiska pocketgenren. När fenomenet dog ut under nästa decennium försvann en betydande plattform för den radikala folkbildningen.

Är du rysk eller?

Vibration thresholds in carpal tunnel syndrome assessed by multiple frequency vibrometry : a case-control study

Background: Carpal tunnel syndrome (CTS) is the most common compression neuropathy, but there is no gold standard for establishing the diagnosis. The ability to feel vibrations in the fingertips is dependent on the function in cutaneous receptors and afferent nerves. Our aim was to investigate vibration perception thresholds (VPTs) in patients with CTS using multi-frequency vibrometry.Methods: Six

The calcium channel subunit gamma-4 is regulated by MafA and necessary for pancreatic beta-cell specification

Voltage-gated Ca2+ (CaV) channels trigger glucose-induced insulin secretion in pancreatic beta-cell and their dysfunction increases diabetes risk. These heteromeric complexes include the main subunit alpha1, and the accessory ones, including subunit gamma that remains unexplored. Here, we demonstrate that CaV gamma subunit 4 (CaVγ4) is downregulated in islets from human donors with diabetes, diabe
