Total Integration of Renewable and Fossil Energy Aiming to a Clean and Sustainable Energy System

Journal of Energy and Power Engineering 2013年第1期7卷 58-65页

This paper presents a new concept of TIRFE （total integration of renewable and fossil energies）, represented by an octagonal structure of all sources, vectors of transmission and optimization of consumption, aiming to a clean and sustainable energy system. The main TIRFE technologies are： cogeneration of H2 and EE （electric energy） by H2-BGSCW/TEU （biomass gasification in supercritical water integrated with a thermoelectric unit）; use of H2 from biomass in oil refinery processes for production of light and clean derivatives; supply of 1-12 deficiency for methanol production from coal; carbon sequestration by a basket of technologies （exhausted petroleum and gas） wells, underground saline aquifers, forests and stockpile of cellulignin-CL-produced from forest residues）; use of H2-BGSCW/TEU as district CHP （combined heat and power） with photovoltaic panels for EE, including electric car battery recharge; optimization of energy consumption by verticalization of the cities replacing low strength materials （bricks and common cement） by high performance concrete with addition of silica from rice husk. TIRFE helps to solve key problems of H2-BGSCW/TEU, such as materials, energy recovery, plugging, corrosion, economics and energy security for the first generation of plants, and organizes the development for the second generation. TIRFE can be incrementally implanted in existent and new cities.

AngiotensinⅡor epinephrine hemodynamic and metabolic responses in the liver of L-NAME induced hypertension and spontaneous hypertensive rats

World Journal of Hepatology 2017年第17期9卷 781-790页

AIM To study hepatic vasoconstriction and glucose release induced by angiotensin(Ang)Ⅱ or Epi in rats with pharmacological hypertension and spontaneously hypertensive rat(SHR).METHODS Isolated liver perfusion was performed following portal vein and vena cava cannulation; AngⅡ or epinephrine(Epi) was injected in bolus and portal pressure monitored; glucose release was measured in perfusate aliquots. RESULTS The portal hypertensive response(PHR) and the glucose release induced by AngⅡ of L-NAME were similar to normal rats(WIS). On the other hand, the PHR inducedby Epi in L-NAME was higher whereas the glucose release was lower compared to WIS. Despite the similar glycogen content, glucose release induced by AngⅡ was lower in SHR compared to Wistar-Kyoto rats although both PHR and glucose release induced by Epi in were similar. CONCLUSION AngⅡ and Epi responses are altered in different ways in these hypertension models. Our results suggest that inhibition of NO production seems to be involved in the hepatic effects induced by Epi but not by AngⅡ; the diminished glucose release induced by AngⅡ in SHR is not related to glycogen content.
