I don't know about Malcolm Gladwell. I've read 3 of his books. All of them fine, but nothing special. All of them fairly superficial with nothing original or innovative. I think his books are very pop culture and should be read in the time frame (say within a year) that

And what this means can't be overstated" (Obama, 2015). The Paris Agreement is ambitious, yet, as Obama pointed out, and despite the continuing very strong growth in the atmospheric burden of CO 2, there is optimism that reaching the target may just be feasible for CO 2 itself.

Control Once monitoring, identification, and action thresholds indicate that pest control is required, and preventive methods are no longer effective or available, IPM programs then evaluate the proper control method both for effectiveness and risk. Effective, less

2020/1/27Anticosti Island is located in the Anticosti sedimentary basin, an Ordovician/Silurian carbonate platform. This platform is mainly composed of limestone and shale with some dolomite and sandstone and reaches up to 5nbsp;km depth in the southwest. It overlies a Precambrian basement of the Grenville Province made of magmatic and metamorphic rocks. Like most remote and off-grid


Strategic planning relies on a number of methods and tools to define and interpret information for comparing alternatives. This chapter identifies selected planning methods according to four purposes: 1. Methods to clarify issues and problems. - All planning teams need creativity and analytical rigor to define problems and compare options.

In this study, Al-sensitive black soybean (Glycine max (L.) Merr.) specimens were treated in Hoagland solutions containing 50–400 M Al for 1–4 days. The measurement for NO3– uptake showed that the NO3– uptake decreased gradually as the Al concentration and treatment time increased, suggesting that Al stress significantly reduced the NO3– uptake by soybean. Under 100-M Al stress

Mining has been a part of the Earth's history since prehistoric times. Mining has played a role throughout the millennia - from Neanderthals' use of stone, to ancient Egyptians', Greeks', Romans' and Incans' more sophisticated mining processes and uses of mined materials. From the Industrial Age and the ability of mass production, societies' progress has led to our Modern times

A method for assessing the environmental impacts of freshwater consumption was developed. This method considers damages to three areas of protection: human health, ecosystem quality, and resources. The method can be used within most existing life-cycle impact assessment (LCIA) methods. The relative importance of water consumption was analyzed by integrating the method into the Eco

2011/7/13The dual nature of expressions T = PX and X = TP T leads to a comparable result when PCA is applied on X or on its transposed X T. The score vectors of one are the eigenvectors of the other. This property is very important and is utilized when we compute the principal components of a matrix using the covariance matrix method (see the pedagogical example below).

A typical meth lab would normally take days to generate a full-size batch of meth, which would require a heat source and dozens, maybe hundreds, of boxes of cold pills. But because the new method uses far less pseudoephedrine, small-time users are able to make the drug in spite of a federal law that bars customers from buying more than 9 grams — roughly 300 pills — a month.

Small- and large-scale mining land acquisitions and mining establishments continue to grow in Zimbabwe, but the question about the development of sustainability remains problematic. While mining establishments can be regarded as vehicles for development, the evidence of positive effects in terms of sustainability in this case is weak.
