Abstract:

Analysis and results are presented from EXOSAT observations of Seyfert type active galactic nuclei (AGN). The sample chosen for study axe 48 hard X-ray selected Seyfert type AGN including all 29 of the emission line AGN in the Piccinotti sample making this the largest such survey to date. EXOSAT, its detectors and methods of data analysis axe detailed, with emphasis on background subtraction techniques. One of the most important new results from EXOSAT data is the discovery that rapid variability (factor 2 over a few thousand seconds) is common in AGN. No evidence is found in the sample source

Abstract:

<p> Researchers have been categorizing asteroids by color for decades in an attempt to better understand asteroid composition and potential links to the meteorite population. However, only recently through large data collection surveys like the Sloan Digital Sky Survey (SDSS) has the asteroid population as a whole been studied. This research will look at a subset of asteroids with the highest reflectivity differences as reported by Carvano et al. (2010) in order to answer the question: Can visible wavelength ambiguous taxonomic asteroid types be an indicator of a non-homogeneous surface? </p>

Abstract:

It has become increasingly clear that many binary systems will pass through a common envelope stage at some point during their evolution. For short period systems composed of main-sequence 0 and early B stars this stage will probably occur for the first time towards the end of hydrogen-core burning in the primary component (case A evolution) rather than during the transition to the giant stage (case B evolution). If masses, radii, luminosities, temperatures and orbital parameters were well determined for a good sample of those systems, it could be established whether the individual components

Liquid ammonia (LNH3) has a number of properties similar to water, such as the ability to dissolve a diverse range of chemical compounds and, based on the variety of chemical reactions in this non-aqueous solvent, speculation has arisen about the possibility of life processes in liquid ammonia. "Life" is difficult to define, but the general consensus is that it is comprised of a variety of individual process that could be regarded as "processes of life", some of which can be modelled within the laboratory.

Arthropod hemocyanin and phenoloxidase are members of a group of proteins called the Type-3 copper oxygen-binding proteins, both possessing a highly conserved oxygen-binding site containing two copper atoms each coordinated by three histidine residues (Decker and Tuczek, 2000). Despite similarities in their active site, these proteins have very different physiological functions. Phenoloxidase possesses both tyrosinase and o-diphenoloxidase activity, and is predominantly involved in reactions which protect insects from infection (Kopàcek et al., 1995).

碩士<br>國立臺灣師範大學<br>生物研究所<br>88<br>α-N-Acetylglucosaminidase (NAGLU) is one of the lysosomal enzymes involved in the stepwise degradation of glycosaminoglycans heparan sulfate. Loss or marked reduction of NAGLU activity results in the autosomal recessive mucopolysaccharidosis type IIIB (MPS IIIB) disease. The purpose of this study was to investigate the molecular lesions of Chinese patients with MPS IIIB. The coding sequences of the NAGLU gene were amplified and examined by single strand conformation polymorphism, heteroduplex, and DNA sequence analyses. Patient 773 has heterozygous mutations;

碩士<br>國立高雄應用科技大學<br>機械與精密工程研究所<br>97<br>This study describes electromechanical analysis of a ring-type piezoelectric transformer, which is operating on the radial mode. The piezoelectric transformer is designed by the geometrical shape, the dimensions, the polarization direction, the direction of external electric field, and the electric electrodes. In this study, the resonant frequency equations for the piezoelectric transformers are derived,and the mode shapes for the piezoelectric rings are also obtained. In addition, finite element analysis method is also used to verify the theoretical res

In recent years, L-type retaining walls are frequently used in the slope area to avoid the invasion of private land and increase the using space. However,the study about stability and mechanical behavior of L-type retaining walls is scarce. This thesis will study the relevant mechanical behavior of L-type retaining walls in order to provide the reference in the design. This study aims at the examp

碩士<br>國立高雄應用科技大學<br>機械與精密工程研究所<br>96<br>The aim of this study is to analyze the electromechanical characteristics of disk-type piezoelectric transformers (PTs). The operating principle of PTs is based on the direct piezoelectric effect and the inverse piezoelectric effect for a piezoelectric material. For a PT, the input electric power can be converted to mechanical vibration energy due to the inverse piezoelectric effect. Also, the output electric power can be indued in the output terminal because of the direct piezoelectric effect. There are two stages of energy conversion operateing in t

碩士<br>國立交通大學<br>物理研究所<br>95<br>In this thesis we study one of the Bianchi type spaces, type II, which is a homogeneous and anisotropic space. We follow the procedure to calculate the Chrystoffel symbols and curvature tensors and obtain the field equations with the variational method. We first consider the Einstein-Hilbert model with perfect fluid and the induced gravity model at early universe. . We gain the numerical solution and test that the scale factor indeed expands. And we also check the induced gravity model that will indeed inflate the space within the $10^{-44}$ to $10^{-36}$

Loss or marked reduction of IDUA activity results in the autosomal recessive mucopolysaccharidosis type I (MPS I) disease. Recently, the IDUA gene was cloned and the cDNA sequence determined. Mutation screening in patients with MPS I identified a number of mutations and polymorphisms within IDUA gene. We had investigated the molecular lesions of a Chinese MPS IH/S patient by RT-PCR (polymerase chain reaction) and DNA sequencing. The resul
