The psychology of concepts has been undergoing significant changes since the early 1970s, when the classical view of concepts was seriously challenged by convincing experimental evidence that conceptual categories never have sharp boundaries. Some researchers recognized already in the early 1970s that fuzzy set theory and fuzzy logic were potentially suitable for modeling of concepts and obtain...

Global air temperature has become the primary metric for judging global climate change. The variability of global temperature on a decadal timescale is still poorly understood. This paper examines further one suggested hypothesis, that variations in solar radiation reaching the surface (Rs) have caused much of the observed decadal temperature variability. Because Rs only heats air during the da...

conclusions the results of the first human pharmacokinetic studies of aminorex were first characterized in 2013. the results suggest that while humans could produce aminorex from levamisole, they probably do not convert very much. even though cases of pah have been reported in cocaine users, the latest pharmacokinetic studies suggest that very little aminorex is actually produced from the inges...

The article examines the extent to which Finnish and Swedish conservative parties adopted neoliberal ideas from 1970s onwards. It does so by comparing their published programmes contextualizing them politically economically. Neoliberalism is understood as an intellectual tradition centred around objective of increasing role market mechanism in society. Concrete programmatic include critiques pu...

Measurement of dietary trends poses methodologic issues of great complexity and intellectural challenge. Confidence in the ability to draw inferences about trends increases when the results of various measurement methods point in the same direction, are of comparable magnitude and are consistent with one another as well as with external sources of related data. This paper illustrates these issu...

Since its introduction in the early 1970s, computed tomography (CT) has undergone tremendous improvements in terms of technology, performance and clinical applications. Based on the historic evolution of CT and basic CT physics, this chapter describes the status quo of the technology and tries to anticipate future developments. Besides the description of key components of CT systems, a special ...

1 It has been known since the early 1970s that the extent and severity of coronary artery disease (CAD) is a predictor of outcomes (1). Multidetector coronary computed tomography (MD-CCT) is a useful diagnostic test in the assessment of CAD (2). Although it is a minimally invasive test, MD-CCT carries attendant risks. There is a risk for development of contrastinduced nephropathy (CIN), which i...
