Sienipilven varjossa : ydinsodan pelko amerikkalaisessa kulttuurissa vuosina 1950-1963
2014
Toinen maailmansota päättyi kahteen Japaniin pudotettuun atomipommiin. Pian amerikkalaisten mielet valtasi huoli siitä, mitä atomipommi voisi tehdä, jos sellainen räjähtäisi Yhdysvaltain maaperällä. Kun Neuvostoliitto vuonna 1949, teki ensimmäisen onnistuneen ydinkokeensa, alkoivat ihmiset toden teolla jopa pelkäämään sitä mahdollisuutta, että se saattaisi hyökätä Yhdysvaltoihin atomipommein. Tätä pelkoa Yhdysvaltain hallinnon oli kitkettävä, jotta minkäänlaista paniikkia ei pääsisi syntymään. Ensimmäinen ohjekirjanen, jossa ihmisille opastettiin kuinka ydinräjähdyksen sattuessa tulisi toimia, ilmestyi vuonna 1950. Atomipommista siirryttiin pian huomattavasti tuhovoimaisempaan vetypommiin, …
Diversidad liquénica asociada a fenómenos post-incendio en los alcornocales valenciano-castellonenses.
2001
FOS, S., CALATAYUD, A. & BARRENO, E. 2001. Lichen diversity associated with post-fire colonization in the Valenciano-castellonense cork-oak forests. Bot. Complutensis 25: 103113. 103 Simón Fos et al. Diversidad liquénica asociada a fenómenos post-incendio... The post-fire colonization of the burned barks of cork-oaks (Quercus suber L.) by epiphytic lichens affected by fire episodes has been studied in different areas of the Valenciano-castellonense cork-oak forests (Asplenio onopteridis-Querco suberis sigmetum). These forests, which have been affected by fires of different intensity, are located in Espadán and Calderona mountains and in the Desierto de Las Palmas and differ with respect…
Spectral theory of a Neumann-Poincaré-type operator and analysis of cloaking by anomalous localized resonance II
2014
If a body of dielectric material is coated by a plasmonic structure of negative dielectric constant with nonzero loss parameter, then cloaking by anomalous localized resonance (CALR) may occur as the loss parameter tends to zero. The aim of this paper is to investigate this phenomenon in two and three dimensions when the coated structure is radial, and the core, shell and matrix are isotropic materials. In two dimensions, we show that if the real part of the permittivity of the shell is $-1$ (under the assumption that the permittivity of the background is $1$), then CALR takes place. If it is different from $-1$, then CALR does not occur. In three dimensions, we show that CALR does not occu…
Toxicological and bioactivity evaluation of blackcurrant press cake, sea buckthorn leaves and bark from Scots pine and Norway spruce extracts under a…
2021
Aqueous extracts from blackcurrant press cake (BC), Norway spruce bark (NS), Scots pine bark (SP), and sea buckthorn leaves (SB) were obtained using maceration and pressurized hot water and tested for their bioactivities. Maceration provided the extraction of higher dry matter contents, including total phenolics (TPC), anthocyanins, and condensed tannins, which also impacted higher antioxidant activity. NS and SB extracts presented the highest mean values of TPC and antioxidant activity. Individually, NS extract presented high contents of proanthocyanidins, resveratrol, and some phenolic acids. In contrast, SB contained a high concentration of ellagitannins, ellagic acid, and quercetin, exp…

Susceptibility of Tortrix viridiana L. to Bacillus thuringiensis var. kurstaki at different level of larval development.
2009
Recently out-breaks of the green oak leaf roller Tortrix viridana L. (Lepidoptera, Tortricidae) were recorded in Natural Reserve in Sicily (Italy) where treatments are generally forbidden. The commercial, social and environmental value of the wood in the forest needs to be preserved and biological control could be applied in particular case. To optimise the permitted biological treatment, not only in terms of product amount but also for the time of application baseline susceptibility of T. viridiana from the Natural Reserve of Ficuzza (Palermo, Italy) to a commercial formulation of Bacillus thuringiensis was determined for neonates and 2, 5, 10 and 15 day old larvae. The differences in susc…
Conflicting conceptualisations of ‘democracy’ in the German Bundestag during the anti-nuclear demonstrations, 1995-2001
2018
A vigorous anti-nuclear movement emerged in Germany in the mid 1990s, when spent nuclear fuel elements began to be transported to the interim storage facility in Gorleben, Lower Saxony. Resistance to nuclear transportation continued to grow in strength throughout the 1990s. The protests expressed people’s distrust and lack of confidence in political institutions and decision-making processes. In the German Bundestag, these events relating to Gorleben caused significant political struggles over the principles and meanings of German democracy. Parliamentarians voiced competing counterarguments about the legitimacy of these demonstrations, on the one hand, and the legitimacy of the nuclear ene…
