Sommario/riassunto |
|
"This is the first resource to fully cover the instrumentation, method development, and applications of Ultra-High Performance Liquid Chromatography (U-HPLC). It details both the benefits and limitations of this method in the pharmaceutical industry, clinical research, the food industry, and environmental services. It covers U-HPLC topics coupled with ultra-violet detector (UV) and mass spectrometer (MS), instrumentation frequently used in solving complex molecules. This is an essential reference for scientists who utilize chromatographic techniques, including in academia, as well as pharmaceutical, biotechnology, chemical, food, environmental, and related industries"-- |

Sommario/riassunto |
|
Joseph B. Soloveitchik’s philosophy plays a significant role in twentieth century Jewish thought. This book focuses on the first stages of Soloveitchik’s philosophy, through a systematic and detailed discussion of his essay Halakhic Man. Schwartz analyzes this essay at three main levels: first, he considers its complex writing style and relates it to Soloveitchik’s aims in the writing of this work. Second, the author compares Halakhic Man to other contemporary writings of Soloveitchik. Third, he lays out the essay’s philosophical background. Through this analysis, Schwartz successfully exposes hidden layers in Halakhic Man, |
