Abstract This book has mostly considered marine contamination and the biological effects of contaminants acting as single stressors. However, environments are rarely exposed to a stressor, but rather experience complex mix many These stressors may be contaminants, such ones discussed in previous chapters (nutrients, chemicals, plastics well carbon dioxide), or they other stressors, invasive spe...

In 14 mongrel dogs, refractory periods were determined in nonischemic and acutely ischemic zones of myocardium during control conditions, 15 minutes after coronary ligation, and 10 and 20 minutes after a procainamide infusion. Following coronary ligation, refractory periods in the nonischemic area remained unchanged (100.8% of control) while in the ischemia area they decreased to 88.6% of contr...

In this paper we present a protocol for unlinkable and anonymous communication in multi hop wireless networks. There exist solutions for unlinkable communication in the internet, such as Tor and Mix networks. These protocols need fixed infrastructure and they are prone to traffic analysis attacks, i.e. where an attacker tries to map communicating devices by performing statistical analysis. Wire...

Traditionally, there are two methods to implement anonymous channels: free-route networks like onion routing and cascade networks like mix network. Each of them has its merits and is suitable for some certain applications of anonymous communication. Both of them have their own drawbacks, so neither of them can satisfy some applications. A third solution to anonymous channels, Klein bottle routi...

Plant species diversity may benefit natural grassland productivity, but its effect in managed grassland systems is not well understood. A four-year multispecies grassland experiment was conducted to investigate the effect of species diversity-legumes and non-leguminous forbs-on productivity, persistence and sward quality under cutting or grazing regimes and with or without slurry application. T...

Sesquiterpene lactone mix detects contact allergy to these compounds present in the plant family Asteraceae. This marker is present in many baseline series. An additional marker is Compositae mix, which is not present in many baseline series. To investigate whether this allergen should be inserted into the Swedish baseline series, six dermatology centres representing the Swedish Contact Dermati...
