A less dusty future?
[1] Atmospheric desert dust is potentially highly sensitive to changes in climate, carbon dioxide and human land use. In this study we use 6 different scenarios of the processes responsible for changes in source areas and explore changes in desert dust loading in pre-industrial and future climates, although all the scenario results are likely to be sensitive to the climate model simulations use...
متن کاملOsteoarthrits: A revolution in treatment
Background: Glucosamine and chondroitin sulfate are integral components of articular cartilage and they have important role to the physiologic and mechanical properties of this tissue. Glucosamine is acting as the precursor of the disaccharide unit in glucosaminoglycans (GAGs) of Cartilage Materials and method: The use of glucosamine and chondroitin sulfate for the symptomatic treatment of os...
متن کاملA Clearer View of a Dusty Sky
The theory of inflation hypothesizes that the Universe underwent a period of rapid expansion less than 10−32 seconds after its birth [1]. If inflation occurred, physicists believe it would have produced large-scale gravitational waves, imprinting a slight swirl-like polarization—known as B modes—on the cosmic microwave background (CMB), the light generated when the Universe was 380,000 years ol...
متن کاملLaunching a Technology Revolution
Despite the huge technological transformation of the global economy in the 20th Century, stabilization of greenhouse gas emissions will require a comparable revolutionary technological change in the 21st Century. While projections of future greenhouse gas (GHG) emissions show large increases in the coming century, the scenarios that underpin these projections already include major improvements ...
متن کاملA dusty plasma device for producing extended, steady state, magnetized, dusty plasma columns
We describe a rotating-drum dust-dispersal device, which we have used, in conjunction with an existing Q machine, to produce extended, steady state, magnetized plasma columns. The dusty plasma device (DPD) is to be used for the investigation of waves in dusty plasmas and of other plasma/dust aspects. The device is capable of generating dusty plasmas in which as much as -90% of the negative char...
