Steam and hot-water heating systems of the late 19th century provided a reasonable means for winter heating, but no practical methods existed for artificial cooling, ventilating, or humidity control.
Several physicochemical methods existed for the treatment and remediation of metal-contaminated environments.
The analytical methods existed for moxifloxacin hydrochloride included determination by spectrophotometry [3 5], and high performance liquid chromatography [6, 7].
The analytical methods existed for prednisolone included determination by micellar electrokinetic chromatography [8], spectrophotometry [9], high performance liquid chromatography [10, 11], and thin layer chromatography densitometry [12].
While other methods existed for ≥0.1 mg of C size samples, the low throughput has made the cost prohibitive for many applications.
In the framework of bioinformatics, various methods existed for inferring biological networks 29 31 aiming to mine underlying networks for identifying biological modules, clustering interactions, and topological features of the network such as degree and betweenness centrality.
