I N A PREVIOUS paper/ the problems concerned with oxygen recovery systems for manned space flight were examined. A procedure was described which led to the purification of the atmosphere and at the same time, permitred the two major atmospheric contaminents, CO s artd H20, to be collected for further use as warranted. It was suggested that the oxygen content of the entrapped water become availa...

This paper shows that prices respond more to increases than to decreases in Value-Added Taxes (VATs). First, using all VAT reforms from 1996 to 2015 across all European countries we show that prices respond 3 to 4 times more to VAT increases than decreases. Second, using a plausibly exogenous VAT reform, we show that the asymmetry persists over several years. Third, we document several empirica...

The water content in seven glass samples from the K/T boundary on Haiti was determined by micro-infrared spectrometry. These glasses are thought to result from impact melting associated with the K/T boundary impact, although this interpretation is not unanimous. The results of the water determinations, 0.013-0.021 wt% H20, show that the Haiti glasses are water-poor. This is a common characteris...

This paper explores how the introduction of an experience rated system of unemployment insurance affects employment and welfare in a model where implicit contracts between firms and workers give rise to wage rigidities and unemployment. In the literature, it has been argued that experience rated systems of unemployment insurance may reduce long term employment as firms anticipate the higher cos...

A partly heuristic attempt at exploring long-run policies aimed at a second-best compromise between ex ante risk-sharing efficiency and ex post productive efficiency. Wage subsidies for low-skilled workers financed by taxes on high wages are advocated, together with improved risk sharing between capital and labour, between generations and between the countries belonging to EMU. The scope of the...

In this paper we estimate the effect of agricultural electricity subsidies in India on groundwater extraction and agricultural output. Our empirical approach exploits changes in state electricity prices over time controlling for aggregate annual shocks and fixed district unobservables. Electricity subsidies meaningfully increase groundwater extraction, where the implied extensive margin price e...

The "differential" method of Achar, Brindley and Sharp (ABS) and the "integral" one of Coats and Redfern (CR) are applied to the dehydration of BaBr2-H20 and HCOOLiH20 and to the thermal decomposition of Pb(SCN)2, and the kinetic parameters so obtained are compared with those deduced isothermally. The results of the ABS method, at the lowest heating rate (q = 1.2 K min— '), agree well with the ...

29Si NMR spectroscopy of concentrated silicate sols, prepared by acid-catalyzed hydrolysis of TEOS in ethanol with H20/Si ratios, r -1.5 or 1.7, followed by alcohol evaporation, shows that the polysilicate species responsible for spinnability are not simple rigid-rod, ladder polymers or linear polymers. Instead a distribution of silicate species is observed consistent with the products of a sta...

It is desired to make a preliminary report of certain experimental evidence that respiratory and other gases may enter one lobule from another in the lung without resort to known anatomical passageways. This was found in vivo and in vitro in work with dogs. In vitro observations. A single lung lobe, freshly secured, was prepared by dissection at the hilus and isolation of the stem bronchus and ...
