dropletbased microfluidics droplet formation methods. in order for droplet formation to occur, two immiscible phases, referred to as the continuous phase (medium in which droplets are generated) and dispersed phase (the droplet phase), must be used. the size of the generated droplets is mainly controlled by the flow rate ratio of the continuous phase and dispersed phase, interfacial tension between two phases, and themineral extraction an overview sciencedirect topicsmineral extraction (mining) and petroleum and gas production are major resource extraction activities that provide the raw materials to support our economic infrastructure. an enormous amount of pollution is generated from the extraction and use of natural resources. the environmental protection agencys toxic releases inventory report lists mining as the single largest source of toxic wastetermsthe iupac compendium of chemical terminology. toggle navigation. g book. resources ab initio calculations ab initio quantum mechanical methods abatement in atmospheric chemistry abeoabiological abiotic abiotic transformation (a\) accelerator in solvent extraction acceptable daily intake acceptable daily intakevijay viswanathan, graham neubig, pengfei liu abstract), and the biocreative v chemical disease relation dataset (wei et al.,). we focus on the task of opendomain documentlevel relation extraction from long, fulltext documents. this is in contrast to the above methods that only use paper abstracts. our
