Air Pollution in New York in the 1950s from LIFE magazine Some people do not trust or cannot absorb the horrific numbers that describe the scale of the damage and deaths from air pollution. The direct benefits (mostly from fewer air pollution deaths and disease) from the 1990 Clean Air Act Amendments are estimated to …
a high temperature superconductor emdrive thruster, which operates at 3.8 GHz, and was designed using an update of the software used for the previous S band designs. Super-conducting surfaces are formed from YBCO thin films on sapphire substrates. Small signal testing at 77 deg K confirmed the design, with a Q of 6.8×106 being measured. …
Eetimes – Directed Self Assembly is gathering momentum to be used in major ways for advanced lithography The technology is moving from the lab to a more serious phase of commercial development. In the event that EUV cannot be made commercially viable, there are several other possibilities for future chip scaling, including DSA. But some …
The science similar to the type used in airport body scanners could soon be used to detect everything from defects in aerospace vehicles or concrete bridges to skin cancer, thanks to researchers at Missouri University of Science and Technology Researchers have developed a patented handheld camera that uses millimeter and microwave signals to non-intrusively peek …
China plans to reduce its energy consumption per unit of GDP, or carbon intensity, by 40 to 45 percent by 2020 based on 2005 level. China has set a target of reducing emissions of lead, mercury, chromium, cadmium and arsenic by 15 percent from 2007 levels over the next five years. China discharged 900 tonnes …
Equations of circuit theory led to a prediction of the memristor almost 40 years before the device was discovered. The equations state relations among four variables: charge (q), current (i), voltage (v) and magnetic flux (phi). Taking these variables in pairs, there are six possible combinations, but only five equations were known 1. (Journal of …
MIT Technology Review – Pershin and Di Ventra begin by creating a kind of a universal maze in the form of a grid of memristors, in other words an array in which each node is connected to another by a memristor and a switch. This can be made to represent any regular maze by switching …
A senior official with the National Development and Reform Commission predicts that China’s economy will be 100 trillion RMB in 2020 Chen Dongqi, vice president of the Academy of Macroeconomic Research, a think tank under the NDRC, said that China’s GDP in 2020 will be equivalent to that of the U.S. in the same year, …
Most economists choose to measure the middle class in terms of income or consumption levels. Taking an absolute approach, a recent study defined the global middle class as those households with daily expenditures between $10 and $100 per person in purchasing power parity terms. The lower bound is chosen with reference to the average poverty …
Schematic of the transmission mode microsphere superlens integrated with a classical optical microscope. The spheres collect the near-field object information and form virtual images that can be captured by the conventional lens. University of Manchester scientists have produced the world’s most powerful optical microscope, which could help understand the causes of many viruses and diseases. …
CloudSleuth by Compuware Gomez is trying to create performance data to compare the speed of different cloud computing services. The average global performance is based on response times gathered from Gomez Last Mile Peers. The response times provided above have been averaged by month from all geographies. More about the sample application being monitored can …
