Emissions of trace gases (CO2, CO, CH4, N2O) resulting from rice straw burning were measured by using the open chamber method. The carbon contained in rice straw was mainly released to the atmosphere as CO2. The percentage of CO2-C emitted in total C in rice straw was in the range of...
Polycaprolactone (PCL) has the advantages of good biocompatibility, appropriate biodegradability, non-toxicity, flexibility, and processability. As a result, PCL-based foams can successfully work in bone tissue engineering, medical patches, drug delivery, reinforcing materials, and other applications. A p...
The DLS indicators range from 0 to 1, representing the percentage of the population in each country for whom the standard of living has reached DLS. We assume that 10 DLS indicators have the same contribution to the total DLS of the country, so the total value of national DLS is the sum...
A total of 285 previously published SD and 145 SI responses to variable CO2 concentrations from a pool of 176 C3 plant species are analyzed here to test the reliability of this method. The percentage of responses inversely responding to CO2 rises from 40 and 36% (for SD and SI, ...
The evolution of the number of aircraft of each category is shown in Fig. 2, where the percentage of the number of flights operated by each aircraft type with respect to the total number of flights is shown from 2004 to 2013. As it was explained in the Introduction, even if the period...
According to the fourth assessment report of the Intergovernmental Panel on Climate Change (IPCC) [Qin et al., 2007], increases in concentrations of greenhouse gases such as CO2 in the atmosphere are considered as one of the main factors inducing global warming, and the anthropogenic combustion ...
This fluorescence is saturated only at 10-5 M DCMU and shows that a certain percentage of photosystem II remains uninhibited at 5 × 10-7 M (Fig. 6), a concentration found to be almost ineffective in inhibiting O2-evolution and 32P-labelling in an N2-atmosphere. The results indicate that...
Preventing a runawayclimate– the rock weathering thermostat Earth’slong-termclimate(over millions of years) is governed by the balance between CO2emitted into theatmosphereby volcanoes, and CO2removed from theatmospherebyweathering of rocks(Kasting 2019). These chemical reactions speed up in warmer...
Generating electric power using CO2 as a reactant is challenging because the electroreduction of CO2 usually requires a large overpotential. Herein, we report the design and development of a polymer electrolyte fuel cell driven by feeding H2 and CO2 to the anode (Pt/C) and cathode (Pt0.8Ru0.2...
Here,QLis latent heat flux from the surface,RLnetis net longwave radiation,RSnetis net shortwave radiation, andQSis the upward sensible heat flux.RTOAis the net radiation at the top of the atmosphere, which balances with ocean heat uptake (i.e., -RTOA)37and we assume land heat uptake ...
