This sector is also the driver for the overall stock increase due to its rather long lifetimes. The stock in the remaining sectors rises in varying degrees of intensity until the late 2000s, whereas afterwards they either slightly decrease or subsequently flatten, depending on their lifetime. ...
Ramjets are more efficient over long distances than rockets but suffer a significant disadvantage: They are useless at low velocities. Consequently, they rely on booster rockets or other vehicles to get them up to speed. Standalone ramjet aircraft typically use hybrid engines [source: NASA]. If...
Therefore, careful outlining and examination of possible pathways to improving health inequalities are crucial to create real, long-term, positive impact instead of artificial outcomes exacerbating inequalities.

We use a Markov approach considering different cost-risk groups to show the possible range of future drug spending in Germany and illustrate the influence of various determinants on pharmaceutical expenditure.#We compute different medium and long-term projections of pharmaceutical expenditure in Germany ...
When we think about the future, we tend to think that it will be "more of the same," which in terms of future health means more medical technology, new and improved drugs and treatments, better health, and longer lives, continuing the steady century-long trend of life expectancy increas-...
