The Paraná delta, growing at a rate of c. 2 km(2) yr(-1) since 6,000 yrs, is one of the most complete records of the Late Holocene in southern South America. The evolution of this 17,400 km(2) delta enclosed in Plata estuary, can be tracked by a series of 343 successive coastal-ridges showing a c.11 years period, in coincidence with sunspot cycle, also found in some North Hemisphere coastal-rid...

California’s medium-grain rice industry experiences a wide range of head rice yield (HRY). Average moisture of a representative paddy rice sample is the commercially used predictor of optimum harvest date to achieve high HRY. A two-year field study demonstrated that average rice moisture alone is not an adequate predictor of HRY. The history of rice moisture caused by varying meteorological con...

Recent investigations show that millimeterwave SAR tomography provides an interesting means for the analysis of forested areas, especially if single-pass systems are employed. Providing very high resolutions in the decimeter domain and highly coherent data also for slightly windy conditions, even individual trees can be considered. Besides, it has been shown that a certain amount of canopy pene...

Objective In May 2012, thousands of protesters, descended on Chicago during the NATO Summit to voice their concern about social and economic inequality. Given the increased numbers of international and domestic visitors to the Windy City and the tension surrounding protesting during the summit, increased monitoring for health events within the city and Chicago metropolitan region was advised. T...

Isolated areas often depend on an independent generation system for its electrical power requirements from both conventional and non-conventional sources due to weak nature of power grid and the difficulty to connect to the power grids. These windy locations are suitable for wind energy conversion systems. The study of behaviour of a self excited induction generator under different operating co...

Both a Cu-26 wt % Ag (Fe-free) alloy and Cu-26 wt % Ag-0.1 wt % Fe (Fe-doping) alloy were subjected to different heat treatments. We studied the precipitation kinetics of Ag and Cu, microstructure evolution, magnetization, hardness, strength, and electrical resistivity of the two alloys. Fe addition was incapable of changing the precipitation kinetics of Ag and Cu; however, it decreased the siz...

College of Rheumatology (ACR) meeting in Chicago this year is the answer to the question, 'Which medical advance was developed in Chicago?' Th is nugget of information was not the product of a lecture or poster session. Rather, it was fl ashed on the computer screen in the shuttle bus that transported me every day from the Palmer House on Monroe Street to the McCormick Place convention center. ...
