Published 1996Staff ViewISSN: 1089-7550Source: AIP Digital ArchiveTopics: PhysicsNotes: CdS thin films with various grain sizes were produced by rf sputtering and in situ postannealing processes. For a series of annealing time intervals, the average grain sizes of an as-deposited thin film with thickness ∼4000 A(ring) were found to vary from ∼280 to ∼1500 A(ring). Three bands located in the green, yellow, and red regions were observed in photoluminescence (PL) spectra of these as-deposited films. The temperature dependence of (PL) spectra of CdS microcrystals was investigated. The variations of the (PL) spectra with average grain size and thickness of CdS thin films were also studied. It was found that the intensity of the yellow band was increased as increasing the film thickness while the intensity of the red band was decreased as the grain size of the film became larger. The peak positions of the yellow and red bands were found to be blue-shifted as the films became thinner. © 1996 American Institute of Physics.Type of Medium: Electronic ResourceURL: -

ISSN: 1365-3091Source: Blackwell Publishing Journal Backfiles 1879-2005Topics: GeosciencesNotes: The origin of the Tertiary ‘red clay’ underlying the Pleistocene loess in the Chinese Loess Plateau remains controversial, although several lines of evidence have suggested a wind-blown origin. This study examines the particle-size parameters of the late Miocene and Pliocene ‘red clay’ by comparing it with those of the late Pleistocene loess. The particle-size distribution of a total of 15 339 loess and 6394 ‘red clay’ samples taken from 12 loess sections along a north–south transect and two ‘red clay’ sequences at Lingtai and Jingchuan was systematically analysed. The median grain size, skewness and kurtosis of the late Pleistocene loess all show a systematic southward change and are principally influenced by distance from source region. The spatial and temporal differentiation of dust deposits is expressed in a skewness–kurtosis–median grain size ternary diagram, from which the distance to the source region can be inferred. The particle-size characteristics of the Tertiary ‘red clay’ sediments are very similar to those of the palaeosols within the late Pleistocene loess deposits, suggesting an aeolian origin for the ‘red clay’. Based on the comparison of ‘red clay’ and loess in the ternary diagrams, it is inferred that the source–sink distance was greater in the Neogene than in the last and penultimate interglacials, and that the dust source region in north-western China underwent a progressive expansion during the period from at least 7·0 Ma to the present.Type of Medium: Electronic ResourceURL: -

ISSN: 1432-1157Source: Springer Online Journal Archives 1860-2000Topics: GeosciencesNotes: Abstract Sedimentary characteristics and processes on an estuarine marsh island in the Yangtze Estuary (East China Sea) show that (1) the mean grain size of the surficial sediments varies between 0.003 and 0.16 mm, the finest sediment being more enriched in the marsh center particularly under calm weather conditions during the flood season, and the coarsest sediment being more enriched on the low seaward tidal flats particularly after storms; (2) the sediment organic carbon content is generally less than 1.4 wt%; (3) the annual vertical marsh accretion is in the range of 20 cm, with a maximum value of 40 cm in the middle of the marsh; and (4) the seasonal cycle in plant growth strongly influences sediment grain size and erosion-accretion events.Type of Medium: Electronic ResourceURL: -

ISSN: 1432-1106Keywords: Hyperthermic treatment ; Apneic hypoxia ; Electroencephalogram ; Heat-shock protein ; RatSource: Springer Online Journal Archives 1860-2000Topics: MedicineNotes: Abstract Electroencephalography (EEG) was utilized for investigating the effect of hyperthermia followed by apneic hypoxia in rats. They were heated whole-bodily to 41° C for 15 min under the control of an artificial rodent ventilator, after drug-induced generalized paralysis. A transcutaneous oxygen saturation monitor was applied to detect the hypoxic condition. EEG was monitored with bipolar needle electrodes. The 72-kDa heatshock protein (HSP72) in brain was analyzed by sodium dodecyl sulfate-polyacrylamide electrophoresis, followed by immunostaining with an anti-HSP72 antibody. There was no difference in the time interval from onset of apneic hypoxia to flat EEG between the hyperthermic and control groups, but cortical electrical activity appeared earlier in the hyperthermia group than the control group, after 90 s of ventilation interruption. The cardiac function did not change in the two groups. The HSP72 synthesis significantly increased in the brain of the rats with hyperthermic treatment.Type of Medium: Electronic ResourceURL: -

ISSN: 1432-1106Keywords: Heat shock protein ; Bicuculline ; Convulsion ; Electroencephalography ; ImmunoblottingSource: Springer Online Journal Archives 1860-2000Topics: MedicineNotes: Abstract Exposure to elevated temperature provokes a sequence of events (heat shock response) in all living organisms. Through this response, heat shock proteins (HSPs) are induced and protect the cells against subsequent injury. We investigated the effect of heat treatment on bicuculline-induced convulsions, and analyzed a possible role of HSPs. Screw electrodes were implanted in the brain of mature male Wistar rats for electroencephalogram (EEG) recording. Experimental rats were subjected to whole-body hyperthermia at 41–42° C for 15 min. Fifteen hours later, bicuculline was injected intra peritoneally to induce convulsions in both experimental and control groups. The heated rats showed a significant attenuation of the convulsive response, in terms of both spike discharges in EEG and clinical seizures. Furthermore, induction of HSP72 was detected in the brain of heat-treated rats by immunoblotting, appearing at 4 h and reaching a maximal level 16–24 h after the heat shock. We conclude that the previous heat treatment stabilized neuronal excitability, most probably through the induction of HSP72.Type of Medium: Electronic ResourceURL: -

ISSN: 1573-4862Keywords: thermography ; infrared scanning ; calibration ; inverse problems ; cavity detection ; NDESource: Springer Online Journal Archives 1860-2000Topics: Electrical Engineering, Measurement and Control TechnologyMathematicsNotes: Abstract An approach for treating nondestructive testing as the solution of inverse problems in mathematical physics has been used for the detection of cavities. The approach is developed based on the use of an additional boundary condition of scanned temperature on the surface to solve for the cavity geometry. For the present study, the condition at the cavity side is taken to be that of a specified temperature, and the experiment is carried out to meet this condition. Two specimens are tested in this paper, a plane slab and a rectangular prism. In both bodies the cavity is rectangular in shape. For the testing of the plane slab, the method is able to detect the cavity wall with high accuracy, whereas the cavity depth error is larger (6%). The detection of the cavity position in the rectangular prism has an error ranging from −9.7 to 7.7%. Errors in the experiment are attributed to the uncertainties in the measurements of temperature and the Biot number. The former is read off from the analog data output of the infrared scanner. The latter is not measured separately, but is computed from the scanned data and thus becomes a portion of the total nondestructive testing output. A final note is also made in this paper to relate how the presented method can be used in actual practice.Type of Medium: Electronic ResourceURL: -

ISSN: 1573-4862Keywords: Thermography ; infrared scanning ; calibration ; inverse problem ; cavity detection ; NDESource: Springer Online Journal Archives 1860-2000Topics: Electrical Engineering, Measurement and Control TechnologyMathematicsNotes: Abstract An inverse problem technique has been developed for detecting irregular cavities in circular cylinders. In this method, the cavity is considered a part of the unknown geometry of the investigated system, and the evaluated temperature is used to locate this geometry. An auxiliary problem is introduced in the solution of this problem; and in the solution, the cavity wall is located by forcing the temperature to satisfy the condition imposed at the cavity. The new methodology is validated by an experiment presented in this paper, and the test results indicate that this method is highly successful in locating cavities. The accuracy of the method is closely related to the accuracy of the temperature that can be measured at the surface. A small error in the surface temperature results in a slight cavity error for deep cavities, while a shallow cavity is not severely affected by a surface temperature error. This method is particularly attractive in detecting shallow cavities in nondestructive evaluation.Type of Medium: Electronic ResourceURL: -
