It was proposed to supply both a visual demonstration of fault-gas data as well as the resources to understand its importance. The Nomograph is built from upright exponential measurements that depict the amounts of various gases. Using this methodology, straight lines are created between neighboring...
Though these results show that identifying the origin of an unknown lithium product is a challenging issue, the large diversity of Li isotopic signatures for secondary products demonstrates that δ7Li values, like a fingerprint, can be a useful tool for certifying the origin of lithium in LIB. ...
Tanco, a leather manufacturer, uses large quantities of common salt to preserve animal hides. New environmental regulations have significantly increased the cost of disposing of salt water that results from this use, and, in consequence, Tanco is considering a plan to use potassium chloride in ...
Large telecommunications companies, private applications, and network providers collect and store enormous quantities of data on users of their products and services, presenting computational challenges for storing and analyzing them. Billions of phone calls must be processed, data from open- and crowd-...
The twin problems faced by modern society of unsustainable dependence on non-renewable fossil resources (escalating demand with respect to supply) and escalating waste problems has the potential to be addressed by employing certain unavoidable wastes as raw materials. Unavoidable wastes such as agri- ...
Using new detection techniques, researchers have found trace amounts of various medicinal substances in lakes and rivers. Taken in large quantities, these substances could have serious health effects, but they are present in quantities far too low to cause any physiological response in people who dr...

while our threat maps represent the impacts on extant species due to threats from human drivers, they omit impacts from pressures that have already led to extirpations or extinctions. For example, in Europe, where a large part of the original fauna has already been lost31, maps of accumulated...
(2) forms the basis of our dynamical model in reduced coordinates. We note that alternative generalizations of the Onsager principle have been proposed using large deviations theory18, but their forms are more complex and hence less amenable to computations. It can be shown that our model has ...
