ESSE 2017. Proceedings of the International Conference on Environmental Science and Sustainable Energy

Environmental science is an interdisciplinary academic field that integrates physical-, biological-, and information sciences to study and solve environmental problems. ESSE - The International Conference on Environmental Science and Sustainable Energy provides a platform for experts, professionals, and researchers to share updated information and stimulate the communication with each other. In 2017 it was held in Suzhou, China June 23-25, 2017

Synthesis of new pyrazolium based tunable aryl alkyl ionic liquids and their use in removal of methylene blue from aqueous solution

In this study, two new pyrazolium based tunable aryl alkyl ionic liquids, 2-ethyl-1-(4-methylphenyl)-3,5- dimethylpyrazolium tetrafluoroborate (3a) and 1-(4-methylphenyl)-2-pentyl-3,5-dimethylpyrazolium tetrafluoroborate (3b), were synthesized via three-step reaction and characterized. The removal of methylene blue (MB) from aqueous solution has been investigated using the synthesized salts as an extractant and methylene chloride as a solvent. The obtained results show that MB was extracted from aqueous solution with high extraction efficiency up to 87 % at room temperature at the natural pH of MB solution. The influence of the alkyl chain length on the properties of the salts and their extraction efficiency of MB was investigated

From Sin to Science: The Cancer Revolution of the Nineteenth Century

This dissertation analyzes the critical importance of the late nineteenth century to the development of a novel, radical approach to cancer that continues into the twenty-first century. From the 1870s to the 1890s, physicians and the public came to understand cancer in an entirely new light, founded upon the application of scientific principles, methods, and instruments to cancer medicine as well as upon a major change in the social perception of the disease. Cancer as it was conceptualized, diagnosed, and treated prior to this revolutionary transformation will be explored. The birth of cellular pathology will set the stage for the transition of cancer from a macroscopic, eponymous malady to a microscopic, cellular disease. The founding of an institution devoted solely to the care of cancer patients and the investigation of the disease will illustrate how societal beliefs, combined with personal tragedy, philanthropy, and medical expertise, legitimized the disease and fostered cancer research. The histories of the cancers of two Presidents of the United States, Ulysses S. Grant and Grover Cleveland, who were diagnosed with the disease only nine years apart during these critical years, will be compared and contrasted for the insights they provide on this great transformation. The scientific underpinnings of these changes will be examined from their roots in physics, chemistry, and biology to their applications in microscopy, anesthesia, and antisepsis. Modern cancer will be shown to be based firmly on the medical microscope and the advent of scientific surgery that occurred in the late nineteenth century
