A combination of man-made and natural resources on earth could provide sufficient He fuel for the technological development of D-He fusion reactors. Helium exists in natural gas wells; however, at the present rate of natural gas usage this resource would provide < 5 kg/yr of He. The radioactive decay of H produced in fission production reactors could yield 110 kg of He by the year 2000 if it we...

[1] Global maps of the Earth’s surface Lambertian equivalent reflectance (LER) are constructed using 3 years of Ozone Monitoring Instrument (OMI) measurements obtained between October 2004 and October 2007 at 23 wavelengths between 328 and 500 nm. The maps are constructed on a 0.5 by 0.5 longitude-latitude grid for each calendar month using an algorithm based on temporal histograms of the obser...

There is a paucity of data on incidence, prevalence and mortality associated with non-cystic fibrosis bronchiectasis.Using the Clinical Practice Research Datalink for participants registered between January 1, 2004 and December 31, 2013, we determined incidence, prevalence and mortality associated with bronchiectasis in the UK and investigated changes over time.The incidence and point prevalenc...

The origin of the major ice-sheet variations during the last 2.7 million years is a long-standing mystery. Neither the dominant 41 000-year cycles in δ18O/ice-volume during the late Pliocene and early Pleistocene nor the latePleistocene oscillations near 100 000 years is a linear (“Milankovitch”) response to summer insolation forcing. Both responses must result from non-linear behavior within t...

AIMS Potassium homeostasis is essential for normal myocardial function, and low serum potassium may cause fatal arrhythmias. However, the association of low potassium and long-term mortality and morbidity in heart failure (HF) is largely unknown. METHODS AND RESULTS We studied 6845 HF patients in the Digitalis Investigation Group trial with serum potassium levels < or =5.5 mEq/L. Of these, 11...

BACKGROUND The Australian National Tobacco Campaign (NTC) was an intensive mass media anti-smoking campaign, the first phase of which commenced in 1997, cost around $A9 million, and reduced smoking prevalence by 1.4%. OBJECTIVE To assess the cost-effectiveness of phase one of the NTC, which ran from June to November 1997. DESIGN AND STUDY POPULATION The quit benefits model (QBM), a Markov-c...
