Although twice as much CaO is required and C and Si losses are greater, CaO is much cheaper. When used with fluorspar it is a viable alternative to CaC2. Sign in to download full-size image Figure 2.29. Effect of type of desulphurizing agent on the rate of desulphurization in a porous...
Bacterial strains under the same species can exhibit different biological properties, making strain-level composition analysis an important step in understanding the dynamics of microbial communities. Metagenomic sequencing has become the major means for

Globally, more than 2 billion tonnes of municipal solid waste (MSW) are generated each year, with that amount anticipated to reach around 3.5 billion tonne
Indigenous Chinese cattle combine taurine and indicine origins and occupy a broad range of different environments. By 50 K SNP genotyping we found a discontinuous distribution of taurine and indicine cattle ancestries with extremes of less than 10% in
