This thesis focuses on understanding the growth and formation mechanism of supermassive black holes (SMBHs), an issue it addresses by investigating the dense interstellar medium that is assumed to be a crucial component of the fuel for SMBHs. The thesis also offers unique guidance on using the Atacama Large Millimeter/submillimeter Array (ALMA) in active galactic nuclei (AGN) research. The author presents the three major findings regarding SMBH formation and growth: (1) The development of a new diagnostic method for the energy sources in galaxies based on submillimeter spectroscopy, which allows identification of accreting SMBHs even in obscured environments, (2) the discovery that the circumnuclear dense gas disk (CND), with a typical size of a few tens of parsecs, which plays a crucial role in governing the growth of SMBHs, and (3) the discovery that the mass transfer budget from the CND to the central SMBHs can be quantitatively understood with a theoretical model incorporating the circumnuclear starburst as a driver of mass transfer. The thesis skillfully reviews these three findings, which have greatly improved our understanding of the growth mechanism of SMBHs.

This book explores the possibility of using micro/nanostructures formed on the doped ice surface as a novel separation platform. In addition, it provides comprehensive information on the nature of freeze-concentrated solutions (FCSs) and the ice/FCS interface, which play important roles in the natural environment and industrial processes alike. The book proposes a novel size-selective separation approach using channels formed on the doped ice surface. The separation is based on the physical interaction of analytes with channel walls, which is controlled by varying the channel width through temperature and dopant concentration changes. It also shows the precise control of the channel width to be in a range of 200 nm-4 m and demonstrates the size-selective separation of microspheres, cells, and DNA. The physicochemical properties of FCSs are measured to reveal the nature of the ice/FCS interface, and the zeta potentials of ice are measured by determining EOF rates in a microchannel fabricated in the ice. The deprotonation at OH dangling bonds and adsorption of ions are also discussed. The viscosities of FCSs confined in micro/nanospaces are evaluated by means of two spectroscopic methods. When an FCS is confined in small spaces surrounded by ice, the viscosity increases compared to that in a bulk solution. Interestingly, this viscosity enhancement occurs even though its size is on the micrometer scale. These parameters are essential to discussing the unique phenomena occurring in FCSs. This book provides an explanation of the scientific processes taking place in FCSs, and reveals the potential that frozen solutions hold as innovative micro/nanofluidic devices and reaction platforms.
This thesis presents new methods for the characterization of vegetable oils, with focus in olive oil, according to geographical and botanical origin, genetic variety and other issues influencing product quality. A wide variety of analytical techniques have been employed, such as various chromatographic techniques (different gas and liquid chromatography methods), an electronic nose, infrared spectroscopy and expert-panel evaluation. Several families of minor compounds, with interest as adulteration markers, have been used for method development, including tocopherols, sterols, phenolics, alcohols, proteins and others. Most methods have been enhanced by the application of multivariate chemometrics. The proposed analytical techniques are of interest to investigate fraudulent actions and practices which are detrimental to product quality.

Nowadays, there are increasing demands for the control and
specification of all aspects of industrial manufacturing. There is
also a growing need to understand various biological processes and
conditions for agricultural production, and concern for protection
of the environment and human health. These factors have made it
imperative to develop adequate methods for the analysis of gaseous
substances or substances that can be converted to the gaseous
state. It is not only necessary to apply known and developed
methods correctly, but novel analytical procedures must also be
found. Instrumentation should be improved and the applications of
these methods will have to be extended.
SELDI is distinct from other TOF-MS technologies in that it couples features of chromatography and mass spectrometry, facilitating analyte enrichment and sample cleanup on an array surface. In the growing field of proteomics, SELDI technology has been widely used for biomarker discovery and characterization in diverse applications including diagnostics, drug development, and basic research. SELDI-based biomarker studies can typically be divided into four phases: discovery, validation, purification and identification, and assay development. SELDI-TOF Mass Spectrometry: Methods and Protocols provides an overview of the current applications of SELDI-TOF MS (surface enhanced laser desorption/ionization time-of-flight mass spectrometry), with an emphasis on study and experimental design, data analysis and interpretation, and assay development. Written in the highly successful Methods in Molecular Biology (TM) series format, chapters contain introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and notes on troubleshooting and avoiding known pitfalls. Authoritative and accessible, SELDI-TOF Mass Spectrometry: Methods and Protocols will provide information on optimizing study design, experimental protocols, and data analysis and interpretation to yield robust biomarkers and biomarker assays, using examples from different disease areas.

The 37th Annual Denver Conference on Applications of X-Ray Analysis was held August 1-5, 1988, at the Sheraton Steamboat Resort and Conference Center, Steamboat Springs, Colorado. As usual, alternating with x-ray diffraction, the emphasis this year was x-ray fluorescence, but as has been the pattern for several occasions over the last few years, the Plenary Session did not deal with that subject, specifically. In an attempt to introduce the audience to one of the new developments in x-ray analysis, the title of the session was "High Brilliance Sources/Applications," and dealt exclusively with synchrotron radiation, a topic which has made a very large impact on the x-ray community over the last decade. As the organizer and co-chairman of the Plenary Session (with Paul Predecki), it is my responsibility to report on that session here. The Conference had the privilege of obtaining the services of some of the preeminent practitioners of research using this remarkable x-ray source; they presented the audience with unusually lucid descriptions of the work which has been accomplished in the development and application of the continuous, high intensity, tunable, polarized and collimated x-rays available from no facility other than these specialized storage rings. The opening lecture (and I use that term intentionally) was an enthusiastic description of "What is Synchrotron Radiation?" by Professor Boris Batterman of Cornell University and the Cornell High Energy Synchrotron Sourc(! (CHESS).
Knowledge is of two kinds. We know a subject ourselves, or we know where we can find information on it Samuel Johnson, 18 April, 1775* Sterols are among the most studied groups of natural products with interest commencing in the 19th century and running to the present. Investigations have embraced the refinement of separation procedures, the development of new analytical techniques and instrumentation for structure elucidation, the unravelling of biosynthetic mechanisms, the determination of the physiological functions of sterols, and the role they play in health and disease. In the past 20-30 years interest in the medical implications of sterol biochemistry, studies on the sterols of plants, algae and fungi, and the identification of the many unusual sterols from marine organisms have proceeded in parallel and somewhat independently. Although the motiva tion and goals for the various lines of investigation have differed widely the researchers working in each of these areas have contributed a wealth of knowledge to the literature relating to the analysis of sterols and many diverse new sterols have been discovered. We conceived this book as a modest attempt to bring together some of this literature in the hope that it may be helpful to newcomers to sterol research. We had originally intended to produce a 'handbook' outlining in detail the protocols to be followed for sterol extraction, chromatography, NMR analysis, etc. in order to identify the components of a sterol mixture."
