Biological diversity encompasses the genetic diversity within each species, the range of species in a given ecosystem e.g. species diversity and the diversity of ecosystems across an entire region (Primack, 2000). At present 1 per cent of the world’s described species are threatened with extinction. The most pervasive and overriding threat is habitat loss and degradation due to human activity such

The short film Swedes in America from 1943, produced by the Office of War Information, is constructed to show in which ways Sweden and the United States should be regarded as two nations nearly identical regarding social and human values. Up until this point, Swedes had in American cinema been portrayed as “the Other” but were now, in the American Second World War propaganda machinery, transformed

TURBT is the initial diagnostic procedure in bladder cancer (BC). Hypothetically, tumor resection could induce seeding of cancer cells into the circulation and subsequent metastatic disease. The objective of this study was to ascertain whether TURBT induces measurable seeding of cancer cells into the vascular system.

Pulsar binaries are important targets for ground-based and future space-borne gravitational-wave (GW) detectors. In order for improving detector design and assessing detector performances, it is a prerequisite to understand the astrophysics of GW sources such as the population size or merger rates. Here, we summarize recent results for Galactic merger rates of two known types of pulsar binaries: (

A pilot-plant study, made to clarify whether biological denitrification is a possible and suitable method for nitrate reduction of drinking water in Sweden is presented. The concentration of nitrate-nitrogen in un-treated water was 10–15 mg/l. The reactor was a 1.2 m aluminium tube with a inner diameter of 0.19 m. 0.75 m was filled with Filtralite®, expanded clay, through which the nitrate-contami

Abstract in Undetermined Comment: Geoengineering efforts to bring oxygen into the deep Baltic should be abandoned, says Daniel J. Conley

I argue along the following lines: For Wollstonecraft, liberty is independence in two different spheres, one presupposing the other. On the one hand, liberty is independence in relation to others, in the sense of not being vulnerable to their whim or arbitrary will. Call this social, or political, liberty. For liberty understood in this way, infringements do not require individual instances of int

Gate arrays are often presented as a convenient means for ASIC prototyping. Obviously, they can both perform the same function and therefore be built from the same behavioral description. Design development implies a process of subsequent parameter bindings, leaving steadily less freedom for the remaining implementation choices. On the other hand, the ASIC offers more place & route freedom tha
