Three plant researchers describe in this book how plants emerged via the fusion of several different types of simple prokaryotic organisms and, through algae, evolved into land plants. During their evolution, they survived global ice ages, violent volcanic eruptions, and collisions with celestial bodies. The authors follow the development of landplants along various paths- some of which have ended
Concerns latest isotopic results of tin metal, tin foils and tin ingots from the Aegean Bronze Age
This special issue introduces the concept of the “entrepreneurship industry” (EI), a rapidly expanding global sector comprising actors, services, and infrastructures that promote and commodify entrepreneurial activity. Moving beyond traditional demand-side views of entrepreneurship, the issue explores how EI shapes entrepreneurial behavior through cultural norms, institutional structures, and poli
Non-representational and materialist theories have enabled geographers to understand subjectivity as something that is interwoven with intimate and dynamic spaces. While previous work has questioned the political efficacy of integrating subjectivity into the environment, this paper traces a ‘new’ problem to the philosophical naturalism of early non-representational work where the subject was const
The chapter maintains that 20th-century decolonisation, unlike previous historical episodes wherein particular empires were resisted and declined, represented a critical juncture at which the very idea of empire was substantively challenged and radically rejected. It led to the establishment of a large number of postcolonial states and signified a decisive reshaping of the international system—bot
A highly standardized 99mTc-sulphur colloid was used to evaluate reticuloendothelial system (RES)-function in the normal rat and after RE blockade by gelatin (Haemaccel). Activity distribution in the animals was measured with a scintillation camera technique. Total uptake of activity in the liver was estimated. From the time-activity curves over the liver, the phagocytic index (kphag) was evaluate
We document that a high level of natural productivity of the ocean - a rich bounty of the sea - has had a positive and persistent impact on economic development since pre-industrial times until today. In addition, we document that it is the bounty of the sea of the ancestors of current populations which drives the persistent effect, not geography per se. We argue that an explanation is that a rich
Purpose: The vast majority of previous studies suggest that there is no relationship between the acceptable noise level (ANL) and pure-tone hearing thresholds reported as the average pure-tone hearing thresholds (pure-tone average). This study aims to explore (a) the relationship between hearing thresholds at individual frequencies and the ANL and (b) a measure of the slope of the audiogram and AN
A brief pedagogical introduction to correlation femtoscopy is given. We then focus on the shape of the correlation function and discuss the possible reasons for its departure from the Gaussian form and better reproduction with a Lévy stable distribution. With the help of Monte Carlo simulations based on asymmetric extension of the Blast-Wave model with resonances we demonstrate possible influence
The water use associated with electricity generation and consumption has been the focus of research for decades. This study provides an overview of the water–electricity nexus from the perspectives of electricity production and consumption. In terms of production, the electricity generation and associated water use for various regions are summarized and compared. The spatial mismatch between water
