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.
Laboratory Animal Models for Brucellosis Research
Brucellosis is a chronic infectious disease caused by Brucella spp., a Gram-negative facultative intracellular pathogen that affects humans and animals, leading to significant impact on public health and animal industry. Human brucellosis is considered the most prevalent bacterial zoonosis in the world and is characterized by fever, weight loss, depression, hepato/splenomegaly, osteoarticular, and genital infections. Relevant aspects of Brucella pathogenesis have been intensively investigated in culture cells and animal models. The mouse is the animal model more commonly used to study chronic infection caused by Brucella. This model is most frequently used to investigate specific pathogenic factors of Brucella spp., to characterize the host immune response, and to evaluate therapeutics and vaccines. Other animal species have been used as models for brucellosis including rats, guinea pigs, and monkeys. This paper discusses the murine and other laboratory animal models for human and animal brucellosis.
