  • G100 portable CO2 incubator analyser for incubators gas readings

    The Geotech G100, which measures CO2 from 0-20%, is used to demonstrate accurate and repeatable CO2 readings of the atmosphere inside incubators. In just a few seconds an embryologist is able to take a reading from various incubators, all of which will have a different means of sampling the air inside an incubator, without fully opening the inner door and adversely affecting the environment. It ...

  • The Cost of Using Global Warming Potentials: Analysing the Trade off Between CO2, CH4 and N2O

    Abstract  The metric governing the trade-off between different greenhouse gases in the Kyoto Protocol, the Global Warming Potentials (GWPs), has received ample critique from both scientific and economic points of view. Here we use an integrated climate-economic optimization model to estimate the cost-effective trade-off between CO2, CH4 and N2O when meeting a temperature stabilization ...

  • Exergy analyses of the biochemical processes of photosynthesis

    This paper gives the exergy analyses of the main biochemical processes of photosynthesis in green plants. In the light reactions, photosystem I, photosystem II, and ATP-synthesis are found to operate at exergy efficiencies of 50%, 68% and 81%, respectively, so that 48% of the exergy of directly utilised solar photons is converted to biochemical energy carriers. Subsequently, in the dark ...

  • Comparison and analysis of the expansion process in a CO2 transcritical cycle

    The isentropic and isenthalpic expansion processes in a CO2 transcritical cycle were analysed thermodynamically. It was found that the effective refrigeration capacity of the cycle with the isentropic expansion process is higher than the cycle with the isenthalpic expansion process. The increment is slightly larger than the expansion work recovered because of the transcritical nature of the ...

  • Monitoring NH3, N2O, CO2 and CH4 emissions

    In France, as in other countries, there is a need to improve knowledge of greenhouse gas and ammonia emissions from livestock production with various management options. The aim of this study was to quantify the NH3, N2O, CO2 and CH4 emissions from two pig solid manure heaps, turned and not turned, in order to examine the effect of turning on gaseous emissions and to obtain additional information ...

  • CO2 emissions mitigation policies and their effects on the Thailand energy system

    Thailand's rate of energy consumption has been growing at a fast pace due to its economic development with a corresponding rapid increase in CO2 emissions. Given the widely accepted fact between CO2 emissions and climate change, mitigation policies in Thailand become an essential part. The analysis is aimed at studying the effects of Thailand's CO2 emissions mitigation options on the energy ...

  • Impact assessment of CO2 emissions caused by exergy losses in the cement sector

    In this study, global effects caused by exergetic inefficiency are examined for rotary kiln of the cement plant. For this purpose, a rotary kiln process of a cement plant in Turkey is modelled, and the annual operation data of this process is analysed. As a first step, an exergy analysis is carried out for all of the thermal processes of the cement plant. Then exergy losses and carbon dioxide ...

  • Analysis of the Chinese energy system: implications for future CO2 emissions

    This paper analyses China's energy resources and their development, energy consumption patterns, historical CO2 emissions, and environmental challenges for the Chinese energy system in the CO2 context. It is shown that China is bound to rely mainly on coal to fuel the development of her economy and thereby improve the Chinese standard of living in the foreseeable future. Given this prospect and ...

  • CO2 emission from cement manufacturing and its driving forces in China

    In China, cement manufacturing has contributed 1788.78 million metric tons of CO2 (carbon equivalent) into atmosphere in the past 35 years (1969-2003). Its driving forces were analysed by a stochastic regression model (STIRPAT), which showed that population was a key driving force and its pressure was higher than the global average level. On the other hand, economic growth had less impact, but a ...

  • Quantitative study of the CO2 emission to the atmosphere from biological scaling laws

    The increase in carbon dioxide (CO2) emissions to the atmosphere from different countries has given rise to one of the most serious environmental problems of our time: global warming. Countries and living organisms are both complex systems in that they use environmental resources to support their own dynamics. Guided by the hypothesis that the behaviour of countries might obey quantifiable ...
