Повний текст джерелаGaseous iodine I131 mainly under I2 or CH3I forms, when released into the atmosphere during a severe nuclear power plant accident may affect both human health and environment. The atmospheric dispersion models of iodine do not take into account the potential reactivity of iodine with atmospheric gas or particles species. However, the modification of the chemical speciation and/or the physical form of iodine compounds is not without consequences on the transport of iodine in the atmosphere and its health effects. Within the framework of improving the atmospheric dispersion tools of radioactive iodine, this work aims to contribute to the actual state of knowledge of atmospheric iodine chemistry by experimental approaches focusing on understanding the CH3I-aerosols and CH3I-water interaction processes.The interaction between CH3I and water at the molecular scale has been investigated using cryogenic matrix experiments supported by theoretical DFT calculations. A large excess of water regarding CH3I was used in order to mimic atmospheric conditions. Dimers and trimers of CH3I are observed despite the high water amount in the initial mixture together with mixed aggregates between CH3I and water polymers. This may be explained by the low affinity of CH3I with water. This result highlights that, in the atmosphere, gaseous CH3I and H2O will likely form aggregates of water and CH3I polymers instead of (CH3I)m-(H2O)n hetero complexes. Further, the interaction between CH3I and amorphous ice as a model of atmospheric ice have been preliminary investigated. The adsorption of CH3I on amorphous has been observed but with a complete desorption of CH3I above 47 K.Experimental study of interaction processes between gaseous iodine (CH3I) and both dry and wet NaCl as surrogate of sea salt aerosols has been carried out using Diffuse Reflectance Infrared Fourier Transformed Spectroscopy (DRIFTS). The DRIFTS spectra of NaCl surface clearly evidenced adsorbed CH3I on the NaCl surface particles. The FTIR spectra revealed new absorption bands that have been not clearly attributed. The adsorption process of CH3I on NaCl is likely a chemisorption since no desorption was observed. We have demonstrated that the adsorption of CH3I on NaCl did not reach saturation even after 5 hours of continuous flow of CH3I. CH3I capture at the NaCl surface presents a 1st order kinetics relative to its gas phase concentration. The uptake coefficients were determined to be in the order of 3 × 10-11, with a global adsorption energy of about -39 kJ.mol− 1. These results show a low probability of CH3I molecules to be captured by NaCl surface. The presence of water on the surface of NaCl seems to have no effect on the interaction between CH3I and NaCl, which is consistent with the low affinity of CH3I for water.The interactions of CH3I with various inorganic and organic powdered solids as models for atmospheric aerosols have been investigated using static reactor coupled with gas chromatography (GC) allowing the monitoring of the gas phase. We have highlighted a weak interaction between CH3I and inorganic and organic aerosols indicating a low affinity of CH3I whatever the aerosol surface composition. We hypothesis that the water content at the aerosol surface is a key parameter. So that, when released in the atmosphere, CH3I will interact very little with the surface of the aerosols and will stay in the gaseous phase. However, although in low content, a part of CH3I is irreversibly adsorbed on the surface of the halide salts that could be considered in the atmospheric iodine model to estimate potential impact

Повний текст джерелаMethyl iodide molecule CH3I has come recently into focus of intense spectroscopic studies due to its role in the ozone layer depletion and its danger for human health in case of an accidental release in the atmosphere. For its atmospheric detection particularly suitable is the nu6 fundamental, which falls into the transparency window at 11 mu m. However, currently available spectroscopic line-shape parameters for CH3I perturbed by main atmospheric species are limited to some extremely scarce measurements at ambient temperature and are missing in spectroscopic databases. To supplement/replace the missing experimental data, in the frame of the French-Russian International Research Project SAMIA, room-temperature (296 K) line-broadening coefficients for the key atmospheric pairs CH3I-CH3I, CH3I-N2, CH3I-O2,CH3I-air are calculated semi-classically, with the use of the Robert-Bonamy formalism improved by exact trajectories, in wide ranges of rotational quantum numbers typically requested by databases (0 < J < 70, K < 20) and for all six sub-branches RP, PP, RQ PQ, RR, PR of the nu6 band; their vibrational dependence as well as sub-branch dependence and temperature dependence (with the traditional power and recently suggested double-power laws) are also addressed. Arguments are given to support this choice of the easily practicable method contrary to its advanced but less agreeing with measurements modifications. Comparisons are made with available measurements and alternative semi-empirical results, indicating the importance of the interaction potential model, in particular of its isotropic part governing the trajectories, for a realistic description of collisional line-widths

Повний текст джерелаThe PIPICO method (photoion-photoion coincidences) by use of synchrotron radiation for molecular ions formation and ion-ion coincidences techniques for the analysis of dissociation parameters allowed the determination of dissociative (or rapidly predissociated) electronic states of doubly charged molecular ions, and measurement of their formation cross sections. State to state studies of the fragmentation of small polyatomic species (CH₄++, CO₂++, NH₃++, CH₃l++). In which both the Initial state of the parent ion and the final states of the fragments are determined, were performed by measuring the kinetic energy of the fragments. Ln the case of CH₃l++ we also studied the fragmentation of doubly charged species following the resonant excitation of 4d inner shell electron of iodine. A part of this thesis is devoted to the SCF calculation with configuration interaction of the electronic energies of doubly charged species

Methyl iodide photolysis has drawn considerable attention over the past years as an “instantaneous” pseudo-linear dissociation that may be described by a two dimensional potential energy surface. Single photon excitation in methyl iodide results in a direct rupture of the C-I bound, and the dissociation occurs in 〜0.1 ps. The Ã-band photodissocation of methyl iodide yields ground state methyl radicals [CH3 X(2A2˝)] and either ground state iodine atoms [(2P3/2)I≡I] or spin-orbit excited iodine atoms [(2P1/2)I≡I*] . In the present work, we used the IR emission technique to study the kinetics of CH3I photolysis. The intensity of 1.315 μm infrared fluorescence from I* (2P1/2) is detected and analyzed. We have studied the influences on I* emissions by a variety of quenchers. Their roles in additional reactions and the quenching mechanism were reported.

[Abstract] The thermal reactions and photochemistry of monolayer methyl iodide (CH3I) on silver covered TiO2(110) surface have been studied by temperature programmed desorption (TPD) and x-ray photoelectron spectroscopy (XPS). Photon irradiation and surface heating result in dissociation of CH3I on Ag/TiO2(110). CH3I desorbs molecularly at Tp = 202 K in TPD study, but with significant fraction (~62 %) dissociating between 130 and 200 K to yield adsorbed I and CH3. The CH3(a) recombine to form C2H6 which desorbs above 270 K with Tp = 288 K. Irradiation of CH3I/Ag/TiO2(110) at cryogenic temperatures results in dissociation and desorption of CH3I. The cross sections for CH3I dissociation and desorption are measured at 251,290,312, 364,403,and 546 nm and are wavelength dependent. While photodissociation is the major mechanism for CH3I depletion after irradiation at longer wavelengths, the nonthermal photodesorption of molecular CH3I becomes the major process at wavelengths below 312 nm. Desorption of CH3 photodissociation fragment is evident. Postirradiation TPD study shows the formation of C2H6 and (CH3)2O. Possible mechanisms for the present thermo- and photochemistry of CH3I on Ag/TiO2(110) are discussed and compared to that on Ag(111)and TiO2(110) surfaces.

The purpose of this thesis is the study of photooxidation of methyl iodie (CH3I) on TiO2 (part I) and SiO2-TiO2 (part II) using Fourier-transformed infrared (FT-IR) spectroscopy. By in-situ monitoring the decrease of CH3I signal and the increase of reaction products, the decomposition efficiency and reaction mechanisms on TiO2-based photocatalysts can be obtained. The nano TiO2 particles employed in part I are prepared by sol-hydrothermal technique with (porous TiO2) and without the interference of SiO2. Most of the CH3I decomposed in the first 4 hours and then its decomposition rates decreased gradually. The product is dependent on the pretreatment of TiO2 sample. With heat treatment, the major products are CH3OH、CO2(g)、HCOOH(a)、CH3OCH3(g) and CH2O(g). Without heat treatment, however, no HCOOH can be observed. The reaction of HT5 TiO2 though heat treatment before photooxdation presented its major products were not inclusive of CH3OCH3, and had relatively high quantity of HCOOH and relatively low quantity of CH2O. Compared with the reaction without heat treatment, its photocatalytic activity is better to decompose CH3I. The time of entire decomposition of CH3I of HT5 TiO2 processing heat treatment was about 20 hours, and the one without heat traetment decomposed CH3I completely using around 30 hours. It is concluded that the decomposion rates of CH3I were solely dependent on the specific surface area of TiO2. For the reaction on SiO2-TiO2 samples (part II), similar major products (CH3OH、CO2(g)、HCOOH(a)、CH3OCH3(g) and CH2O(g)) were found. The photooxidation efficiency can be enhanced by low quantity of mixed SiO2. However, excessive SiO2 decreases the photocatalytic activity in the decomposition of methyl iodide. Possible reaction mechanism is proposed and discussed in the thesis.

Irradiation with a mercury lamp at 254 nm of a p-H2 matrix containing CH3I and SO2 at 3.2 K, followed by annealing of the matrix, produced prominent features at 633.8, 917.5, 1071.1 (1072.2), 1272.5 (1273.0, 1273.6), and 1416.0 cm−1, attributable to ν11 (C−S stretching), ν10 (CH3 wagging), ν8 (SO2 symmetric stretching), ν7 (SO2 antisymmetric stretching), and ν4 (CH2 scissoring) modes of methylsulfonyl radical (CH3SO2), respectively; lines listed in parentheses are weaker lines likely associated with species in a different matrix environment. Further irradiation at 365 nm diminishes these features and produced SO2 and CH3. Additional features at 1150.1 and 1353.1 (1352.7) cm−1 are tentatively assigned to the SO2 symmetric and antisymmetric stretching modes of ISO2. These assignments are based on comparison of observed vibrational wavenumbers and 18O- and 34S-isotopic shifts with those predicted with the B3P86 method. Our results agree with the previous report of transient IR absorption bands of gaseous CH3SO2 at 1280 and 1076 cm−1. These results demonstrate that the cage effect of solid p-H2 is diminished so that CH3 radicals, produced via UV photodissociation of CH3I in situ, might react with SO2 to form CH3SO2 during irradiation and upon annealing. Observation of CH3SO2 but not CH3OSO is consistent with the theoretical predictions that only the former reactions proceed via a barrierless path.

This thesis is composed of two major parts. The first part is to construct an Electron Spectroscopy for Chemical Analysis (ESCA) system. The second part is to perform the in-situ study of the photo reactions of methyl iodide on sol-gel prepared TiO2 particles by Fourier Transform Infrared Spectroscopy (FTIR). The Electron Spectroscopy for Chemical Analysis system is one of the most important instruments for surface analysis. It includes an ultra high vacuum (UHV) system, a sputtering ion gun for surface cleaning, a flood gun for neutralizing the sample charged after X-ray source irradiated, an X-Ray gun and a Centric Hemisphere Analyzer (CHA) for electron energy analysis. The ultra high vacuum optimal pressure after baking is<6.5×10-11 torr. This system is now ready for public service. The photo catalytic reaction of methyl iodide on TiO2 nanoparticles from titanium alkoxide via sol-gel technique was studied using Fourier transform infrared spectroscopy. The TiO2 was characterized by XRD, ESCA, BET, and TEM. In the presence of oxygen, the methyl iodide decomposed to form CO2(g) and CH2O(g) after UV irradiation. In thermal reaction, no signification reaction was observed at temperatures below 373 K. At temperatures above 523 K, the methyl iodide was oxidized to form CO2(g) which is the major product. Small amount of CO(g) was also formed.

There is a close connection between Chinese novels and Chinese operas in the development of literature and art in China. The fascinating stories in “Liao-Chai Chi-I” (Strange Stories from the Leisure Studio) have become a primary source for playwriting, which is a distinct feature of Chinese operas in the Ching Dynasty. The study aims to analyze 14 Chinese operas adapted from “Liao-Chai Chi-I.” First, a brief introduction to the history of Chinese operas in the Ching Dynasty will be discussed, as well as the backgrounds of the eight playwrights introduced in the study. Then, acting, scenes, movements, songs, dialogues, costumes, and stage effects in the operas adapted from “Liao-Chai Chi-I” will be examined. Finally, the presentation of stories, characterization, motifs, and the use of language between the based-on-novel operas and “Liao-Chai Chi-I” will be investigated. It is hoped that, by examining the operas in detail, the achievements, effects, and statuses of the based-on-Liao-Chai operas can be clearly presented.

The concluded results were as followed: (I) There were significant differences in travel motivation among the variables of visitors’ ages, professions, income, marital status, participation of ecological societies and guided tour services. (II) There also existed considerable differences in environment awareness and willingness of revisiting among the variables of ages, levels of education, professions, income, marital status, participation times, participation of ecological societies and guided tour services. (III) There was an obvious positive correlation among each travel motivation, environment awareness and willingness of revisiting, where the correlation between “eco-professional knowledge” and “willingness of revisiting” in travel motivation was the highest; the positive correlation among “environment interpretation”, “environment affection”, “environment perception” and “environment evaluation” in environment awareness and in “willingness of revisiting” was medium. (IV) “Eco-professional knowledge” in travel motivation, and “environment affection”, “environment perception” and “environment evaluation” in terms of environment awareness could be predicted evidently in willingness of revisiting.

Landslides Triggered by Chi-Chi Earthquake Hsuan Wu Liao Abstract A large number of landslides were triggered by the Chi-Chi Earthquake (ML 7.3) on 21 September 1999. These landslides have been mapped from satellite images in this study. By using GIS (Geographic Information System) as a tool, we can construct a GIS table of landslides triggered by the earthquake and analyze their characteristics, including types, distribution, areas and numbers, …etc. The distribution and areas of landslides have been compared with the distance from the earthquake foci, rock types, faults, roads, rivers, hill slopes and slope directions. There were 9272 landslides occurred during earthquake shaking within the area greater than 625 square meters and total area of landslides is 127.8 square kilometers. There were 8843 landslides located within the area of PGA value 250gal and above. These landslides were distributed in an ellipse-shaped region with the major axis striking NNE, coinciding with the trend of regional faults. Statistics shows the following results: (1) Landslides almost located within the area that PGA greater than 250gal, especially within the area that PGA greater than 300gal. (2) A lot of landslides occurred within 20Km from the fault rupture plane. The longest distance from the rupture plane located at the interval of 60 to 70 Km. (3) the Toukoshan Formation, The Chinsui Shale and the Tachien Sandstone were more easily influenced by the earthquake shaking, especially at Huoyenshan Facies. (4) slopes with inclination larger than 100% involves more landslides. (5) At the hanging wall, most slopes collapsed at S and SE facing. At the foot wall, most slopes collapsed at S , SE and SW facing, whereas slopes facing to other directions were not so seriously damaged. It shows that the main movement of Chi-Chi earthquake is from SE to NW.

Повний текст джерелаLoosely speaking, a (n,1)-surface is a very nicely immersed π₁-injective surface in a 3-manifold. Its concept was born around 1981 by Peter Scott in his work on Seifet fibered spaces. It has been shown that if a 3-manifold M contains a (4,1)-surface, then its universal cover is R³ and π₁(M) determines M up to homeomorphism. Homotopic homeomorphisms are isotopic on a 3-manifold containing a (3,1)-surface. On the other hand, some class of 3-manifolds, such as manifolds with nonpositive cubing, by Aitchison and Rubinstein, are known to contain (4,1)-surfaces. One natural question, then, is how 'big' is the set of 3-manifolds with (4,1)-surfaces in the set of all 3-manifolds. Similar question for embedded π₁-injective surfaces, called incompressible surfaces, has been answered in a work of Floyd and Oertel around 1980. They showed th a t the set of incompressible surfaces in a 3-manifold is carried by a finite number of branched surfaces. Combining this with a theorem of Hatcher, one can reasonably argue that 3-manifolds containing incompressible surfaces, called Haken manifolds, are scarce. In this paper we prove a similar result in the context of (3,1)-surfaces and non Haken 3-manifolds.
Theorem 1 If M is a non Haken 3-manifold, then the set o f (3,1)-surfaces in M are embeddedly carried by a finite number of branched surfaces.
'Embeddedly carried' is a precise generalization of 'carried' in the context of immersed surfaces. Careful examination of when the theorem is not true will lead one to obtain a sequence of least area embedded disks in M that limits to an essential measured lamination of M. Such lamination always approximates an incompressible surface in M . In some cases euler characteristic of the lamination is zero, hence M has an essential torus. We strongly suspect this is actually true in all cases. We hope that this method generalizes to the context of (4,1)-surfaces in any 3-manifold. This would establish some kind of finiteness property for (4,1)-surfaces in a 3-manifold, as in the case of incompressible surfaces.

Four hundred forty-six observation recorded data of Chi-Chi earthquake were obtained. Because of the huge amount of seismic data, it becomes difficult to analysis. This study uses computer graphics techniques to implement the Chi-Chi earthquake visualization system. The goal is to help scientist better understand. Through the visual analysis, we clearly observe the energy release. It provides important information for disaster prevention. We used GMT to generate a series of energy map. We found that the energy distribution was different under different geology condition. Visual technique transforms values into graphs. It reduces time on analysis research, it also provide helpful information for scientists and seismologists. It offers useful information for disaster prevention.

INTRIDUCTION Try another aspect to explore the new spacial model in order to distinguish the tranditional museum design. FIRST:THE CONCEPT OF ECOMUSEUM PLANNING The new design concept of the Museum of Chi-Chi and Train Station is similar to the Ecomuseum, which is to conbinate its own natural, historical and visiting resourses. SECOND:THE SPECIAL DESIGN OF DISPLAY--BASED ON THE HISTORY OF REGION TO DEVELOP A NEW TYPE OF DESIGN SOURSE. THIRD:THE CONFIGUATION-THE INTERACTION BETWEEN MUSEUM AND NATURE Try a new manipulation to combine the configuation of the Museum and Nature. Three major topics : 1IN GENERAL : Attempting to manipulate several coherent factors in Chi-Chi, such as the nature surrounding and the process of regional development. 2.IN CONTEXTUAL : To maintain the "EXTENSIVE" quality in the area of Train Station. 3.TO CONVEY THE IMAGE OF SPACE : To convey the tranditional spacial idea to the new generation.-1 -aThe Museum of Chi-Chi and Train Station

Recently, there is a trend toward “Eastern Body” in the world of arts. Many predecessors found their inspiration from Tai Chi Chuan, Qi Kung, Yoga, and meditation. Because of the great interests in this trend, body exploration, and practice in Tai Chi Chuan and dancing, the author constructed this article for those who work with and communicate with their own bodies. As proposed above, this study tried to build up “the Body Perspectives of Tai Chi” In the thought of Tai Chi, theories on discrimination of Yin-Yang, interactions among five elements, and manifestations of eight trigrams(Ba-Kua)were adopted for observing the relationship between body and environment. On the other hand, operation and symptoms appeared in the body were discussed with the aspects of Qi, motor principles, effort analysis, and practice methods in Chuan.As a result, combining these two major frames, the whole construction of “the Body Perspectives of Tai Chi” was developed. Hermeneutics and reference analysis were chosen for study methods. The core stand is “Tai Chi- Body” introduced by traditional Chinese Taoists, Chinese medicine doctors, and Tai Chi Chuan experts. Additional statements were reviewed from Qi Kung, Somatics, Eastern Body culturology, the trend toward Eastern Body in Dancing.
