Cost Risk Tolerance Area of Material Supply in Biomass Power Generation
This research aims to shed light on the interaction mechanism of cost risks for biomass material supply in power generation. Firstly, game model is established to analyze interactions among factors including unit procurement cost, unit transportation cost, basic price and coal price for cop residue collection. Secondly, Monte Carlo simulation is implemented based on two profit ratio to compare the profit increase under material competition with that under price alliance. Thirdly, risk tolerance area approach is applied in mapping of cost risk. Shi Liquan Biomass Power Plant in Shandong Province of China is analyzed as a case to show that price alliance will benefit both the allied enterprises and the local collection area by the proposed methodology.
Study on the distribution and quantity of biomass residues resource in China
The distribution and quantity of biomass residues resource in China have been evaluated. Agricultural and forest residue as two main categories of biomass residues resource have been investigated. The study shows that the unused agricultural and forest residues account for 51.9% and 45.8% of the total residues available as an energy resource in China.
Improved culture method for the isolation of Histoplasma capsulatum and Blastomyces dermatitidis form contaminated specimens.
Studies were performed to evaluate a method for selective isolation of Histoplasma capsulatum and Blastomyces dermatitidis from contaminated specimens. Ammonium hydroxide placed on an agar medium surface was found to inhibit the growth of many bacteria, yeasts, and saphrophytic fungi normally found in specimens such as animal tissues and sputum. In one study involving the culture of B. dermatitidis from canine tissues, 24% more isolations were obtained on a medium using NH4OH compared with a similar medium. Increases in the isolation of H. capusulatum from sputum specimens were also obtained, ranging from 20 to 32% compared with four other media without NH4OH.
