    Notes: ZnS:Tm and ZnS:Tm,Cl thin films were grown by metalorganic chemical vapor deposition (MOCVD), using diethylzinc, H2S, Tm(thd)3 (thd=2,2,6,6-tetramethyl-3,5-heptanedione), and HCl. The ZnS:Tm did not contain oxygen which might be introduced through the thd-radical. It thus has only codopant-free Tm3+ luminescent centers probably associated with native defects. The electroluminescence (EL) spectrum of the ZnS:Tm,Cl showed three satellite emission lines in addition to the original emission of the ZnS:Tm, indicating the existence of Tm–Cl complex centers. In contrast, the photoluminescence (PL) spectrum of the ZnS:Tm,Cl under host excitation showed no discernible satellite emission lines. Hence, though the Tm ions in the Tm–Cl complex centers are expected to be charge compensated by Cl or a certain Cl-induced defect, they are rather inactive in the PL excitation while active in the EL excitation. The same properties were observed for the MOCVD-grown ZnS:Sm and ZnS:Sm,Cl [A. Kato, M. Katayama, A. Mizutani, N. Ito, and T. Hattori, J. Appl. Phys. 77, 4616 (1995)], and therefore they probably occur for other rare-earth luminescent centers with Cl codopant. © 1997 American Institute of Physics.

    ZnS:Sm grown by metalorganic chemical vapor deposition with Cl codoping (1995)

    Notes: Sm-doped ZnS thin films were grown by metalorganic chemical vapor deposition using diethyl- zinc, H2S, Sm(thd)3 (thd=2,2,6,6-tetramethyl-3,5-heptanedione), Sm(hfa)3 (hfa=1,1,1,5,5,5- hexafluoro-2,4-pentanedione), SmCl3, and HCl. The following films were prepared: an undoped ZnS, a ZnS:Sm grown with Sm(thd)3 and without HCl, a ZnS:Sm,Cl grown with both Sm(thd)3 and HCl, a ZnS:Cl grown only with HCl, and a ZnS:SmCl3 grown with SmCl3. Very little Sm was incorporated when Sm(hfa)3 was used as the dopant source. In the ZnS:Sm, the Sm was not segregated at grain boundaries, at least at concentrations below 0.2 at. %. In the ZnS:Sm and the ZnS:Sm,Cl, the (200), (220), and (311) reflections of the cubic structure that the undoped ZnS and the ZnS:Cl exhibited were not detected, and preference for the (00⋅1) hexagonal orientation became stronger. The electroluminescence spectrum of the ZnS:Sm,Cl showed three satellite peaks appearing in each of the 7 nm ranges around the three dominant peaks seen in the ZnS:Sm. The total electroluminescence intensity of the ZnS:Sm,Cl increased as a result of the appearance of the satellite peaks. While the ZnS:Sm,Cl showed photoluminescence attributed to the self-activated centers, its intensity was less than 10−2 of that of the ZnS:Cl. A model is suggested that Sm-VZn (zinc vacancy)-Cl complex centers are formed by the Cl codoping and give rise to the satellite peaks. © 1995 American Institute of Physics.

    Significance of hematoma size for evaluating the grade of blunt renal trauma (1999)
    Melbourne, Australia : Blackwell Science Pty
    International journal of urology 6 (1999), S. 0

    Notes: Abstract Background : The hematoma size relative to the body size was measured on computed tomography films using a personal computer system in order to define whether that parameter is useful for decision-making in the management of blunt renal trauma. Methods : From 1982 to 1997, 33 patients with intermediate or severe grade blunt renal trauma were retrospectively divided into three groups: group 1, managed conservatively without transcatheter embolization; group 2, managed by bedrest after selective transcatheter embolization; and group 3, managed operatively. In these three groups, the hematoma area (H) and the ratio of hematoma area to body area on CT (H/B) were measured and the chronological changes of the H/B in groups 1 and 2 were studied. Results : The H and H/B of group 3 were significantly larger than those of group 1. The H/B was more clearly distinguished for each group compared with the H alone. Well-preserved kidney integrity, despite the presence of a large hematoma in group 2, allowed the conservative treatment following transcatheter embolization of the bleeding site. The H/B of all group 1 patients gradually decreased and on the 40th or 50th day after injury they reached a level equivalent to the ratio of contra-lateral normal kidney area to body area. Conclusion : The ratio of hematoma area to body area on CT was very useful in evaluating the grade of blunt renal trauma. In conservative treatment for blunt renal trauma changes of the hematoma size is a useful indicator for management.

    Relationships between nucleic acid, nitrogen, and growth rate of tobacco cells in suspension culture (1981)

    Notes: Summary Changes in the amount of nucleic acid and nitrogen, and the relationships between these amounts and the growth rate of tobacco cells (Nicotiana tabacum L. cv. Bright Yellow-2) at different initial nitrogen concentrations in the medium, were examined in batch cultures. During culture in basal medium, the amount of intracellular nucleic acid expressed per unit of dry biomass was 36.3 mg RNA g−1 cell and 8.1 mg DNA g−1 cell at the beginning of batch culture. These values increased 2.5 fold for RNA and 1.5 fold for DNA during the exponential growth phase and then gradually decreased with the decline in the growth rate. Similar changes were also observed in the medium containing less nitrogen. The specific growth rate, μ (day−1), of the culture corresponded to the magnitude of the intracellular RNA content (mg RNA g−1 cell), and the linear relationship, RNA=38μ+23 was obtained. In addition, there were remarkable positive correlations between the total and protein nitrogen, and μ during the cultures. The mononucleotide composition of total RNA (AMP+UMP)/(GMP+CMP) which was suggested to be a convenient index of metabolic activity was nearly constant (0.78 to 0.80) during tobacco cell culture in the basal medium.

    Notes: Abstract Purpose Several case reports indicate critical respiratory complications in relation to the double-lumen endobronchial tube (DLT). A prospective survey for the airway problems in using the DLT is presented. Methods One hundred adult patients undergoing thoracotomy for lung cancer were investigated. Tube malposition and airway obstruction were searched using a fiber-optic scope. The endobronchial cuff was positioned just below the trachcal carina while the trachea was intubated with a DLT (Rüsch). The distances of displacement, from the tracheal carina to the bronchial cuff, were measured during anesthesia using an epidural catheter, which had marks every 5 mm. The distances for correcting the tube position were measured at both the bronchial cuff and the level of the teethPaO2,PaCO2 andSPO2 were also measured. Results Malposition (displacement over 5 mm from the correct position) was found in 42 patients, and 40 of them were in a withdrawal direction, occurring at the postural change and during one-lung ventilation, especially during manipulation of the lung hilum. Correcting distances at the level of the teeth were 15.3–3-times longer than those at the bronchial cuff. Airway deformities and gradual withdrawal of the bronchial cuff were found in association with surgical manipulation. Obstruction occurred at the tips of the tracheal tube in four patients and the bronchial tube in six patients, and at the tip of both in two patients. Hypoxemia (PaO2〈60 mmHg) occurred in four patients and hypercapnea (PaCO2〉60 mm Hg) in two patients. Conclusion Most of the DLT obstructions were associated with withdrawal malposition. Great attention to DLT displacement and airway deformity is advised.
