Selenium in its organic and inorganic forms has been shown to inhibit the development of chemically induced, spontaneous and transplanted tumors. The present investigation was performed to study the effect of selenium (4 μg per ml of drinking water) on tumorigenesis of adenovirus‐type‐9‐induced breast fibroadenomas and on 1,2‐dimethylhydrazine‐induced bowel carcinogenesis in WF rats. It was found

After inoculation of adenovirus type 9 into newborn Wistar/Furth rats, seven out of seven females developed one or several mammary fibroadenomas within 14–25 weeks after virus inoculation. No tumours were observed in male rats inoculated with the same virus or in untreated controls. Neonatal inoculations of adenovirus type 5, produced on the same HeLa cells, gave negative results in both sexes. Th

We assess how global shocks propagate from global manufacturing firms to local service providers through a spatial variation in export-driven service demand. We show that a 1% increase in a localised measure of exporting increases sales of service firms by around 0.08%. We also show that this link is local as the effect fades away after just 20 km, that it is more pronounced with larger and foreig

Degrowth thought and strategies suffer from a tension between viewing the state as incapable of initiating transformational change and making a political appeal to it to do precisely this via targeted eco-social policies. While a small number of academic papers has theoretically addressed this tension, there is a lack in research on the strategic implications arising from conceptualizations of the

News item in section labelled "People, Companies in Cryogenics", about a new musical composition which was the result of a collaboration between John Weisend (scientist and CSA Board Chairman) of the European Spallation Source and Mike Edgerton of Lund University.

It is unclear how to address PTSD in the context of chronic pain management. Here we examine the potential benefits of an addition of prolonged exposure (PE) therapy for PTSD for adults attending multidisciplinary CBT for chronic pain. Four adults seeking treatment for chronic pain from a specialized pain rehabilitation service were offered PE for PTSD using a replicated, randomized, single-case e

This study examines how public diplomacy practitioners deal with gender dynamics as a form of ideological issue in foreignpolicy. Informed by the theory of discursive closure, this study focuses on understanding how Swedish public diplomacypractitioners make sense of the country’s feminist foreign policy in their daily work and what consequences this has for thecommunication of it. Based on semi-s

Previous research has acknowledged the effect of prosody on inter-gestural coordination, but specifically the effect of tones is still understudied. This paper has a two-fold purpose. First, it aims to explore effects of the Swedish word accents on word-initial consonant–vowel (CV) coarticulation. Second, it aims to revisit the existing evidence for tonal integration.

Soil microorganisms play an integral role in the regulation of carbon (C) cycling. In high-latitude ecosystems, climate warming is leading to higher plant productivity, shrub expansion and faster nutrient cycling; all of which increase resource availability to soil microorganisms. To understand how a legacy of enhanced resource availability affects the functional traits of microbial communities, a

This paper presents a differential eight-path bandpass filter with tunable center frequency and bandwidth. Fully differential Miller compensated Butterworth Gm-C biquads are used to implement the active low-pass filters required in the structure of the eight-path filter. The -3-dB bandwidth of each Gm-C filter can be tuned from 2.5 to 51 MHz by means of six digital bits. The center frequency of th

The effect of clock skew and duty-cycle on the performance of high-Q N-phase band-pass filters (BPFs) have been examined in this paper. Following a mathematical approach and using the analytical derivations carried out, the effects of such non-idealities as clock skew and duty-cycle error are determined in an N-path filter. It is analytically proved that image signals from all integer multiples of

A high-Q, tunable, bandpass filtered amplifier structure is proposed which is based on a novel Q enhancement technique in N-path filters. Using Fourier series analysis, frequency response of an N-path filter as well as the aliasing effects which are present in it are derived. Frequency translation of unwanted contents at higher frequencies to the center frequency of the bandpass filter is called h

Organisms are continually challenged by multiple threats in the environment, and such threats are seldom constant in either time or space. Therefore, organisms must maintain physiological, behavioural, morphological and life- history adaptations across environments to prevent reductions in fitness. Freshwater ecosystems are particularly variable environments, and so organisms inhabiting lakes and

Om platser verkligen är av betydelse, vilket ekonomiska geografer anser, då måste de vara som mest betydelsefulla för de människor vars liv utspelar sig på dessa platser, och upplever världen, materiellt kan kulturellt, genom den. När en kris och efterföljande osäkerheter drabbar en plats så påverkar detta främst människorna som kallar denna platsen för sitt hem. Ibland till den grad att en del avIf places indeed matter, as economic geographers believe, then it must matter most to the people who live their everyday lives in these places and experience the world materially and socially through it. When a crisis hits and uncertainty ensues, it affects people who call these places home the most. So much so, that some of them might be willing to stake a claim on its recovery, and development t
