The Institute for Clinical and Economic Review analyzed the economic value of two interventions for congestive heart failure: Swiss pharmaceutical giant Novartis' new drug Entresto and a St. Jude Medical system known as CardioMEMS HF for monitoring increases in pulmonary artery pressure.
A cold desert is a desert that has snow in the winter instead of just dropping a few degrees in temperature like they would in a Hot and Dry Desert. It never gets warm enough for plants to grow. Just maybe a few grasses and mosses.The animals in Cold Deserts also have to burrow but in this case to keep warm, not cool.he precipitation in Hot and Dry Deserts and the precipitation in Cold Deserts is different. Hot and Dry Deserts usually have very little rainfall and/or concentrated rainfall in short periods between long rainless periods.
They can be covered by sand, rock, salt lakes, stony hills and even mountains. Most non-polar deserts are hot in the day and chilly at night. The temperature in the daytime can reach 50 Â°C or higher in the summer, and dip to 0 Â°C or lower at night time in the winter. The largest hot desert in the world is the Sahara in North Africa. It is almost as large as Europe or the United States. The Sahara desert is also the hottest desert in the world.
