Six species of grass (four C3 and two C4) from southeastern Australian native pastures were grown in controlled environment cabinets at current (~370 !!mol CO2 mol-I) and twice current (~750 !!mol CO2 mol-I) cabinet [C02l. Photosynthetic gas exchange and aboveground biomass were estimated after seven weeks. Cabinet [C02l had a highly significant impact on above-ground biomass (P<0.0003) with pl...

The atmospheric concentration of C02 has undergone significant and fairly regular changes on a time scale of 100 kyr during the at least last four glacial-interglacial cycles. Here we present a novel coupled physical-biogeochemical mechanism for these variations. Previous studies had to arbitrarily specify the behavior of the physical climate system in order to invoke a biogeochemical mechanism...

CO 2 is the determining factor of global warming, affecting intensity and rate warming. Although outbreak COVID-19 deeply affected emission carbon, impact on temporal variation spatial distribution (E ) not yet conclusive. This study systematically analyzed spatial-temporal E C0 from 2019 to 2021 based one latest near real-time dataset named GRACED. Studies show that has no significant in world...

C1402 is fixed in pyrimidines of nucleic acids by Brucella abortus, strain 6232, during growth on complex artificial media (Newton et al., 1954). The incorporation of C02 into pyrimidines appears to be more obligatory in this strain of B. abortus which requires an increased pCO2 than it is in Escherichia coli (Bolton et al., 1952); a finding which suggested that strains of B. abortus which requ...

We introduce a subexponential algorithm for geometric solving of multivariate polynomial equation systems whose bit complexity depends mainly on intrinsic geometric invariants of the solution set. ¿From this algorithm, we derive a new procedure for the decision of consistency of polynomial equation systems whose bit complexity is subexponential, too. As a byproduct, we analyze the division of a...

DEWAN [1938] and Adler et al. [1939] reported that certain enzyme preparations obtained from heart muscle bring about a reductive amination of ac-ketoglutaric acid. The hydrogen required in this reaction may be provided from other dehydrogenase systems via coenzyme I or II, especially from the ,-hydroxybutyric and i8ocitric dehydrogenases, according to the schemes: (1) ac-ketoglutaric acid+NH3+...

Rapid transformatIon of discoid hemoglobin SS erythrocytes into grossly distorted sickled forms suggests alteration of surface/volume ratio. We, therefore, examined the effect of deoxygenation on red cell volume. ‘31llaholed albumin was used as a marker of plasma volume in normal (Hb AA), sickle (Hb SS), and sickle-C (Hb SC) blood. Heparinized blood was incubated for 30 mm at 37#{176}Cin a tpno...

The concept of unreliable failure detector was introduced by Chandra and Toueg as a mechanism that provides information about process failures. This mechanism has been used to solve several agreement problems, like Consensus. In this paper, algorithms that implement failure detectors in partially synchronous systems are presented. First two simple algorithms of the weakest class to solve Consen...
