To improve vehicles environmental performance, different strategies have been explored namely to reduce the use stage energy. In order avoid problem shifting, a life cycle perspective should be used compare alternative solutions. This paper aims existing studies focused on energy (LCE) of analyze impacts and benefits regarding two trending improvement strategies: lightweight materials powertrai...

On the basis of study of domestic and foreign experts, according to the existing energy structure and present status of transportation industry, comparing and analyzing the energy consumption and low-carbon economy indicators of different modes of transportation, this paper put forward the thinking of constructing low-carbon comprehensive transport system, which takes railway as main and also c...

As to the global warming, China has confidence in the development of the economy by bearing responsibility and obligation toward curbing global warming, which at this time can be achieved by reducing carbon emissions. Industry is an important material production department in the national economy, and plays a leading role in the national economy. Chinese industrial production is mainly based on...

The present study was designed to investigate the protective effect of ethanol extracts from Lindera coreana leaves (LCE) on UVB-induced oxidative stress in HaCaT keratinocytes. The HaCaT cells were pretreated with LCE for 24 h and then exposed to UVB (20 mJ/cm(2)) for 2 h. UVB significantly decreased the cell viability (p<0.05). LCE did not exhibit significantly cytotoxic effects and increased...

With the development of new generation technology and the low-carbon economy, the smart low-carbon city has become one of the academic hotspots. Many studies on it have begun; however, the dynamic mechanism is rarely involved. Therefore, this paper uses the Technique for Order Preference by Similarity to an Ideal Solution (TOPSIS) method to creatively take a quantitative study on a Chinese smar...

Previous studies have shown the high diagnostic accuracy of narrow-band imaging magnifying endoscopy (NBI-ME) and Lugol chromoendoscopy with pink-color sign assessment (LCE-PS) for superficial esophageal squamous cell carcinoma (SESCC). However, there has been no controlled trial comparing these two diagnostic techniques. We conducted a randomized noninferiority trial to compare the diagnostic ...

Aiming at the problems existing in low-carbon technology of Chinese manufacturing industries, such as irrational energy structure, lack of technological innovation, financial constraints, this paper puts forward the suggestion that the leading role of the government is combined with the roles of enterprises and market. That is, through increasing the governmental funding the adjustment of the i...

Objective To study and analyze the life-cycle carbon emissions of existing rural residential energy retrofit projects to provide theoretical data support for local green development sustainable construction. Methods Life cycle analysis (LCA) was used compare life (LCE) a envelope efficiency retrofitting project in central Gansu. Results It found that dwellings have very high potential retrofitt...

Aquatic photosynthetic organisms can modulate their photosynthesis to acclimate to CO₂-limiting stress by inducing a carbon-concentrating mechanism (CCM) that includes carbonic anhydrases and inorganic carbon (Ci) transporters. However, to date, Ci-specific transporters have not been well characterized in eukaryotic algae. Previously, a Chlamydomonas reinhardtii mutant (lcr1) was identified tha...
