bird flu but were not diagnosed because their symptoms were too mild. The findings suggest some populations have developed natural resistance to the virus. The study of more than 45,000 people in Vietnam, reveals that up to 750 people are likely to have become infected with the strain after handling sick birds. Anna Thorson, who led the study, said the real figure potentially extended into thou...

In this issue of the Health Care Financing Review, we focus on consumer information for the Medicare population. Over the last several years the Centers for Medicare & Medicaid Services (CMS) has increased its efforts to provide clear and useful information to Medicare beneficia­ ries to help them make more informed health care decisions. The emphasis on consumer information increased dramati­ ...

S PC is SPC is discussed with a view to indicating its implications not only to manufacturing and quality but to research and product development as well. In the manufacturing/quality area, the efforts and methods attending full-scale implementation of SPC are briefly reviewed with special reference to the differences inherent in powder making versus manufacturing of parts. SPC charting techniq...

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...
