Apparent hydrogen consumption in acid reactors: observations and implications

open access: yesWater Science and Technology, 2009
Investigations of hydrogen production by dark fermentation have received increasing attention as a green fuel production process. Research focus is mainly on yields and rates of hydrogen production under different operation conditions. The importance of hydrogen consumption is addressed here, based on results from lab-scale reactors.

Seeing farmers' markets: Theoretical and media perspectives on new sites of exchange in New Zealand [PDF]

open access: yes, 2009
In this paper we explore the extent to which a reciprocal relationship exists between contemporary theorisation about farmers' markets in geography and the rapidly expanding public discourse surrounding these sites of exchange in New Zealand.

Is the Apparent Cardioprotective Effect of Recent Alcohol Consumption Due to Confounding by Prodromal Symptoms? [PDF]

open access: yesAmerican Journal of Epidemiology, 2000
Previous research has reported a protective association between alcohol drinking and acute coronary heart disease in the 24-hour period after drinking. This study investigated whether this apparent protective association resulted from confounding due to the effect of prodromal symptoms on drinking behavior. In 1992, the authors conducted a case-control

What Can Explain the Apparent Lack of International Consumption Risk Sharing? [PDF]

open access: yesJournal of Political Economy, 1996
Recent research in international business cycles finds that international consumption comovements do not match the risk-sharing predictions of standard complete markets models. In this paper, I ask whether two different types of explanations can help explain this result: (1) nonseparabilities between tradables and nontradable leisure or goods and (2 ...

Apparent uncoupling of energy production and consumption in long-lived Clk mutants of Caenorhabditis elegans [PDF]

open access: yesCurrent Biology, 1999
Clk mutants of Caenorhabditis elegans are characterised by an overall slow down of temporal processes and increase in life span. It was hypothesised that Clk mutations slow down the pace of many cellular functions and lower the rate of energy metabolism, possibly resulting in slower production of reactive oxygen species which in turn could result in ...
