Reducing carbon emissions is a major way to achieve green development and sustainability for China’s future. This paper elaborates the detailed features of China’s carbon flow for 2013 with the carbon flow chart and shows the changing characteristics of China’s CO2 flow from the viewpoint of specific sectors and energies from 2000 and 2013. The results show that (1) from 2000 to 2013, China’s C...

As part of different climate change action plans, countries all around the world have made commitments to reduce their CO2 emissions. These commitments have motivated different lines of research in the field of electrical power system that try to find the best solutions to supply the increasing electric demand while moving away from the conventional generation sources, which are mainly based on...

Principle of 13C-octanoic Acid Breath Test The rationale of 13C-octanoic acid breath test (13C-OBT) to measure gastric emptying of solids is based on (1) the firm retention of 13C-octanoic acid in the solid phase of a standard test meal during its passage through the gastric environment, followed by (2) a rapid disintegration of the solid phase in the duodenum with (3) subsequent absorption of ...

The sensilla ampullacea on the apical antennomere of the leaf-cutting ant Atta sexdens were investigated regarding both their responses to CO2 and their ultrastructure. By staining the sensillum during recording, we confirmed that the sensilla ampullacea are responsible for CO2 perception. We showed that the sensory neurons of the sensilla ampullacea are continuously active without adaptation d...

CO2 fluxes and concentrations were simulated in the planetary boundary layer above subarctic hilly terrain using a three dimensional model. The model solves the transport equations in the local scale and includes a vegetation sub-model. A WMO/GAW background concentration measurement site and an ecosystem flux measurement site are located inside the modeled region at a hilltop and above a mixed ...

Highly porous N-doped carbon materials with apparent surface areas in the 1300 2400 m g range and pore volumes up to 1.2 cm g have been synthesized from hydrothermal carbons obtained from mixtures of algae and glucose. The porosity of these materials is made up of uniform micropores, most of them having sizes < 1 nm. Moreover, they have N contents in the 1.1 4.7 wt% range, this heteroatom being...

Global warming is big issue of this time. It is caused by producing emissions, mainly carbon dioxide. Many organizations tries to establish restrictions to limit CO2 emissions. Our aim is to monitor underground parking lots and detect level of carbon dioxide using wireless sensor network. Gained results are drawn in the map of pollution of monitored area.

Biofilms typically exist as complex communities comprising multiple species with the ability to adapt to a variety of harsh conditions. In clinical settings, antibiotic treatments based on planktonic susceptibility tests are often ineffective against biofilm infections. Using a CO2 evolution measurement system we delineated the real-time metabolic response in continuous flow biofilms to strepto...

We have analyzed monthly hydrological, meteorological and water quality data from three irrigation and drinking water reservoirs in the lower Jordan River basin and estimated the atmospheric emission rates of CO2. The data were collected between 2006 and 2013 and show that the reservoirs, which differ in size and age, were net sources of CO2. The estimated surface fluxes were comparable in magn...

Burning fuels in an O2/H2O atmosphere is regarded as the next generation of oxy-fuel combustion for CO2 capture and storage (CCS). By combining oxy-fuel combustion and biomass utilization technology, CO2 emissions could be further reduced. Therefore, this work focuses on investigating the combustion characteristics of single particles from bituminous coal (BC) and pine sawdust (PS) in O2/N2, O2...
