On-line microwave-based preconcentration device for inductively coupled plasma atomic emission spectrometry: Application to the elemental analysis of spirit samples

A microwave-based thermal nebulizer (MWTN) has been employed for the first time as on-line preconcentration device in inductively coupled plasma atomic emission spectrometry (ICP-AES). By the appropriate selection of the experimental conditions, the MWTN could be either operated as a conventional thermal nebulizer or as on-line analyte preconcentration and nebulization device. Thus, when operating at microwave power values above 100 W and highly concentrated alcohol solutions, the amount of energy per solvent mass liquid unit (EMR) is high enough to completely evaporate the solvent inside the system and, as a consequence, the analyte is deposited (and then preconcentrated) on the inner walls of the MWTN capillary. When reducing the EMR to the appropriate value (e.g., by reducing the microwave power at a constant sample uptake rate) the retained analyte is swept along by the liquid-gas stream and an analyte-enriched aerosol is generated and next introduced into the plasma cell. Emission signals obtained with the MWTN operating in preconcentration-nebulization mode improved when increasing preconcentration time and sample uptake rate as well as when decreasing the nozzle inner diameter. When running with pure ethanol solution at its optimum experimental conditions, the MWTN in preconcentration-nebulization mode afforded limits of detection up to one order of magnitude lowers than those obtained operating the MWTN exclusively as a nebulizer. To validate the method, the multi-element analysis (i.e. Al, Ca, Cd, Cr, Cu, Fe, K, Mg, Mn, Na, Pb and Zn) of different commercial spirit samples in ICP-AES has been performed. Analyte recoveries for all the elements studied ranged between 93% and 107% and the dynamic linear range covered up to 4 orders of magnitude (i.e. from 0.1 to 1000 μg L−1). In these analysis, both MWTN operating modes afforded similar results. Nevertheless, the preconcentration-nebulization mode permits to determine a higher number of analytes due to its higher detection capabilities.

John Winthrop's proposal respecting electrical globes and jars, ca. 1758

In this proposal, John Winthrop explains the need to replace damaged "electric globes" used in the College's collection of scientific apparatus. He states that Benjamin Franklin, at the time residing in London, was willing to seek replacement globes for the College's collection. Winthrop then proceeds to assert that the College should acquire "square bottles, of a moderate size, fitted in a wooden box, like what they call case bottles for spirits" instead of the large jars included in the scientific apparatus, because those jars cracked frequently.

Observations Medical & Chirurgical by John Perkins, 1724-1774 (inclusive)

Volume kept by Dr. John Perkins (1698-1781) from 1724 to 1774 recording observations on various diseases and medical conditions illustrated with cases from Perkins's practice in Boston, Massachusetts. The cases ranged from epileptic fits, various fevers, and rheumatism to melancholy. His treament methods were standard for the era, mainly prescribing vomits, purges, and spirits, and bleeding patients. Also includes a section listing contradictory opinions among prominent medical writers such as Dutch physician Herman Boerhaave and English physician Thomas Sydenham. An index is located at the end of the volume. Perkins likely began compiling the book in 1765. It contains cases dating from 1724 to 1774.

The Financial Crisis and the Future of the Eurozone. Bruges European Economic Policy (BEEP) Briefing 21/2010

The government debt crisis, erupted in the Eurozone in 2009, nearly led to the collapse of European monetary union. Now that this has been averted, the question is what should be done to make the Eurozone sustainable in the long run. The survival of the Eurozone hinges on the capacity of its leaders to improve the eurozone's governance. With the exception of Greece, the root cause of the government debt crisis has little to do with the poor performance of the SGP, rather, with unsustainable debt accumulation by private actors. Also, the method of convergence implicit in the SGP has not worked well – macroeconomic divergences have stubbornly remained for nearly a decade and several countries experienced boom and bust dynamics. Although strong declines in real interest rates may explain part of the story (but e.g. Italy did not experience boom & bust), self-fulfilling waves of optimism and pessimism which might be called 'animal spirits' and are of mainly national origin, seem a good candidate for explanation. These national animal spirits endogenously trigger credit expansion and contraction. It follows that (national) movements of credit ought to be under much firmer control and this is up to the monetary authorities, including the ECB. Critical recommendations for better governance of the Eurozone should therefore combine credible measures to maintain fiscal discipline over the medium term with such instruments as minimum reserve requirements to control the growth of bank credit as well as minimum reserve requirements in different national banking systems. Finally, the idea of adding more sanctions to the SGP may be ill-conceived since, in future, it might pre-empt national governments to come to the rescue of banks (under credible threats of contagion) and/or prevent a downward spiral in economic activity.
