Laboratory selections for resistance of Tribolium castaneum, adults to low oxygen concentrations (LOC) and high carbon dioxide concentrations (HCC) have shown that this species is capable of developing low but significant levels of resistance to the respective modified atmospheres (MAs). Also resistance obtained in adults was partially transferred to the eggs and larvae. Studies on the modes of...

A combination of clinical, radiological, and physiological changes commonly called 'emphy-sema' is so often confirmed at necropsy that it is interesting to find that some patients whose condition seemed to be clinically indistinguishable from emphysema during life did not in fact have it. In a large series of patients who were intensively studied during life in a clinic for 'emphysematous' pati...

Internal attack of chromium containing alloys in mixed oxygen-chlorine environments occurs by the formation of pores which penetrate down grain boundaries of the alloys. No internal attack was detected in a binary Fe-20 %Cr alloy at 1200 K in environments containing 2500 ppm C12. The rate of internal attack of alloy 800H in such environments was increased by replacing the O2 in the gas by C02 ....

Can shorter maturity European options be statically hedged with longer maturity plain vanilla options? This problem appears for example when analyzing options on forwards in relation to liquid options on the spot underlying. Under mild assumptions on the underlying security price process and on the option’s payoff function we show that approximate static hedges exist und we provide a recipe for...

Since the time of Pasteur quantitative differences in the rate of fermentation or respiration have been reported for yeast developed under different oxygen tensions. Fermentative activity in the majority of cases has been based on rates of C02 production, although to a limited extent rates of glucose utilization and the rates of alcohol formation have also been employed. It should be emphasized...
