    ‘Do-It-Yourself’ Attenuated Total Reflectance Cell Designed and Constructed in a Laboratory Course: A Versatile and Economical Alternative to Commercial Designs (1997)

    Notes: Abstract An attenuated total internal reflectance (ATR) cell has been designed and constructed by a group of four undergraduate and graduate students during an advanced laboratory course in the School of Chemical Engineering at Purdue University. Details for the assembly, which utilizes commercially available optical components, are given in this paper. The cell employs a 45-degree trapezoidal ZnSe crystal as the ATR element. Both spherical and flat gold-coated mirrors are used to focus and align the IR beam. The cell design presented here not only provides practical instrumentation design and implementation experience for students, it also has four major advantages imporatant for teaching purposes: a) It can be ported between different FTIR spectrometers with similar sample-compartment sizes; b) it provides an economical means for ATR spectroscopy in laboratory courses as the cost of this cell is less than half the price of similar commercial cells; c) all optical parts of the cell are easily accessible and visible for demonstration and adjustment purposes; and d) it can serve as a starting point for a variety of student experiments.

    Description / Table of Contents: Résumé Sur la base de données anatomiques obtenues lors de précédents travaux sur l'anatomie vasculaire de la main, l'architecture vasculaire palmaire a été étudiée sur 60 extrémités supérieures de cadavres d'adultes, non embaumés. Chaque paume a été divisée en 64 carrés par 8 sections sagittales et 8 sections transversales. L'architecture vasculaire à l'intérieur des carrés et les relations artérielles entre eux ont été étudiées et mesurées par angiographie, dissection au microscope opérateur et reconstruction computérisée en 3D. Les paumes amputées ont été regroupées en 4 types d'après la distribution des vaisseaux sanguins. Les données anatomiques concernant les anastomoses vasculaires sont précisées. Il existe trois zones clés pour l'irrigation de la paume. Leur importance quant à l'irrigation de la main est exposée. Outre la division des paumes amputées transversalement en 4 types, le programme de réparation de vaisseaux dans les 4 types d'amputations obliques communes de la paume et aussi discuté.
    Notes: Summary Based on the anatomic data obtained from earlier studies on the vascular anatomy of the hand, the vascular architecture in the palm of the hand was studied on 60 sides of unembalmed adult upper extremities. Each palm was divided into 64 squares by 8 sagittal and 8 transverse sections. The vascular architecture in these squares and the arterial relations between them were observed and measured by angiography, operative microscopic dissection and computerised three-dimensional reconstruction. According to the pattern of the blood-vessels, the amputated palms can be classified into 4 types. The anatomic basis for the vascular anastomosis in each type is defined. There are three key-areas for the blood-supply of the palm and their significance is discussed. Apart from the 4 types of transversely amputated palms, the repair programe of the blood-vessles in 4 types of common obliquely amputated palms are also discussed.

    Eigenvalue sensitivity analysis of stiffened plates with respect to the location of stiffeners (1998)

    Notes: Abstract This paper formulates the eigenvalue sensitivity of a stiffened plate with respect to stiffener location; the analysis is based on the generalized Rayleigh quotient of the combined platebeam system. The results show that the eigenvalue sensitivity is proportional to the force between the plate and the stiffener as well as to the slope of the eigenfunction at the interface between the plate and the stiffener.

    Seismic Source Characteristics of Nine Strong Earthquakes from 1988 to 1990 and Earthquake Activity since 1970 in the Sichuan-Qinghai-Xizang (Tibet) Zone of China (2000)

    Notes: Abstract —The Chinese provinces of Sichuan, Qinghai and Xizang (Tibet) are situated in a very active seismic zone. From 1988 to 1990, nine strong earthquakes (M 〉 5.9) occurred in these provinces. A method of analyzing seismic waveforms using apparent source time functions (aSTF) and apparent time differences (aTD) is adopted to derive rupture characteristics for the strong earthquakes. Combining the source characteristics with aftershock data, regional tectonics and geology, this paper examines the migration of strong earthquakes. The Qinghai earthquakes in this study were found to have strong reverse-slip faulting, which is different from the strike-slip focal mechanisms of past earthquakes in the region. The steepness of compressional axes of Sichuan earthquakes is related to the local complicated tectonics. Finally, the single-link cluster (SLC) method is used to analyze the spatial-temporal behavior of the all strong earthquakes that occurred in the region since 1970. The SLC analysis suggests that the patterns of earthquake activity can be identified well and that continental earthquakes occur seemingly with basic regularity.

    Special speleothems in cement-grouting tunnels and their implications of the atmospheric CO2 sink (1998)
    Springer

    Details
    ISSN: 1432-0495
    Keywords: Key words Speleothem ; Cement grouting ; Atmospheric CO2 sink
    Source: Springer Online Journal Archives 1860-2000
    Topics: Geosciences
    Notes: Abstract  Based on the analyses and comparisons of water chemistry, stable carbon isotopes and deposition rates of speleothems, the authors found that there are two kinds of speleothems in the tunnels at the Wujiangdu Dam site, Guizhou, China, namely the CO2-outgassing type and the CO2-absorbing type. The former is natural, as observed in general karst caves, and the product of karst processes under natural conditions. The latter, however, is special, resulting from the carbonation of a cement-grouting curtain and concrete. Due to the quick absorption of CO2 from the surrounding atmosphere, evidenced by the low CO2 content in the air and the high deposition rate of speleothems (as high as 10 cm/a) in the tunnels, the contribution of the carbonation process to the sink of CO2 in the atmosphere is important (in the order of magnitude of 108 tons c/a) and should be taken into consideration in the study of the global carbon cycle because of the use of cement on a worldwide scale.

    Contribution of carbonate rock weathering to the atmospheric CO2 sink (2000)
    Springer
    Environmental geology 39 (2000), S. 1053-1058 
    Details
    ISSN: 1432-0495
    Keywords: Key words Carbonate rock weathering ; Soil CO2 ; Atmospheric CO2 sink
    Source: Springer Online Journal Archives 1860-2000
    Topics: Geosciences
    Notes: Abstract To accurately predict future CO2 levels in the atmosphere, which is crucial in predicting global climate change, the sources and sinks of the atmospheric CO2 and their change over time must be determined. In this paper, some typical cases are examined using published and unpublished data. Firstly, the sensitivity of carbonate rock weathering (including the effects by both dissolution and reprecipitation of carbonate) to the change of soil CO2 and runoff will be discussed, and then the net amount of CO2 removed from the atmosphere in the carbonate rock areas of mainland China and the world will be determined by the hydrochem-discharge and carbonate-rock-tablet methods, to obtain an estimate of the contribution of carbonate rock weathering to the atmospheric CO2 sink. These contributions are about 0.018 billion metric tons of carbon/a and 0.11 billion metric tons of carbon/a for China and the world, respectively. Further, by the DBL (Diffusion Boundary Layer)-model calculation, the potential CO2 sink by carbonate rock dissolution is estimated to be 0.41 billion metric tons of carbon/a for the world. Therefore, the potential CO2 source by carbonate reprecipitation is 0.3 billion metric tons of carbon/a.

    Analysis and interpretation of instantaneous turbulent velocity fields (2000)

    Notes: Abstract Methods of analyzing and interpreting velocity-field data (both two- and three-dimensional) to understand the kinematics, dynamics, and scales of turbulence are discussed. Reynolds decomposition and vorticity are traditionally used; however, several other methods, including Galilean (constant convection velocity) and LES decompositions (low-pass filtering), in conjunction with critical-point analysis of the local velocity gradient tensor, reveal more about the structure of turbulence. Once the small-scale structures have been identified, it is necessary to assess their importance to the overall dynamics of the turbulence by visualizing the motions they induce and the stresses they impose both on other small-scale vortices and on the larger-scale field.
