    High responsivity HgCdTe heterojunction photoconductor (1985)
    [S.l.] : American Institute of Physics (AIP)
    Journal of Applied Physics 58 (1985), S. 2360-2370

    Notes: We present an experimental and theoretical study of n-type Hg1−xCdxTe photoconductors in which a large band-gap alloy was grown on top of a smaller band-gap active region and contacts were made to the larger gap material. The larger band-gap material causes an energy barrier to holes which decreases the rate at which they reach the high recombination region of the metal-semiconductor interface. As a result, this heterojunction contact greatly reduces the effects of carrier sweepout on device performance and leads to much higher detector responsivities. Experimental results in a symmetric device with a cutoff wavelength of 7.8 μm at 77 K show responsivities in excess of 106 V/W and detectivities close to the background limited value and nonsaturation of responsivity with bias voltage. In an asymmetric device, in which only one heterojunction contact was used, an order of magnitude increase in responsivity was observed when the heterojunction contact was biased to attract minority carriers, compared with the opposite bias polarity. A theoretical model of the heterojunction contact photoconductor is presented. Calculated results are in good agreement with experimental results. The results of the calculation suggest that the optimum compositional difference Δx of the two layers should be Δx∼0.04, and that the thickness of the large band-gap region should be 2–3 μm.

    Annealing of ion implanted silver colloids in glass (1993)
    [S.l.] : American Institute of Physics (AIP)
    Journal of Applied Physics 74 (1993), S. 5754-5756

    Notes: Silver colloids have been formed by ion implantation in float glass. Subsequent annealing methods alter the size distribution and optical reflectivity of the colloids. Furnace anneals and rapid flame heating convert large colloids into smaller units but excimer laser annealing appears to cause a dissolution of silver into the glass network.

    Anaesthesia for thoracoscopic pleurectomy and ligation of bullae (1992)

    Topics: Medicine
    Notes: A patient is described who, despite severe pre-operative respiratory disability, had her persistent pneumothorax successfully managed by thoracoscopic pleurectomy. The technique causes considerably less pain and interference with respiratory function postoperatively than does conventional thoracotomy. Potential anaesthetic problems arise because of the necessity of insufflating carbon dioxide at pressures of up to 1 kPa to maintain a pneumothorax during surgery.

    The aerodynamic characteristics of cat allergen (1993)
    Oxford, UK : Blackwell Publishing Ltd
    Clinical & experimental allergy 23 (1993), S. 0 
    Details
    ISSN: 1365-2222

    Topics: Medicine
    Notes: To further characterize airborne cat allergen and a newly established cat challenge facility, airborne Fel d I levels and particle size distributions were studied in both the cat challenge room and home environments under different conditions of ventilation and physical activity. In the cat room, there has been a dramatic and continued rise in the concentration of airborne Fel d I since the room was established. No differences in total airborne Fel d I levels or particle size distribution were detected under widely differing rates of ventilation (40 air changes per hour vs 8 ac/hr vs 〈 1 ac/hr). Likewise, altering ventilation had little effect on the clearance of airborne antigen after disturbance. Significant increases in allergen levels were detected, however, after simply allowing the cats to leave their holding cage and move about the room, Feld I levels in homes ranged from 2–468.5 ng/m3 similar to the levels seen in the cat room without disturbance. Feld I particle size distribution was very consistent in both homes and the cat room with the majority of airborne Fel d I being detected on particles 〉 17 μm. Although very little allergen f 〈 15%) was detected on particles 〈4 μm, this important fraction was present under all conditions. We conclude that airborne cat allergen resides primarily on relatively large particles, that a small but consistent fraction is found on very small particles, and that neither allergen levels or particles size distribution are significantly influenced by ventilation.

    Pharmacological manipulation of adynamic ileus: controlled randomized double-blind study of ceruletide on intestinal motor activity after elective abdominal surgery (1988)
    Oxford, UK : Blackwell Publishing Ltd
    Alimentary pharmacology & therapeutics 2 (1988), S. 0

    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Medicine
    Notes: In a double-blind placebo-controlled trial of patients undergoing elective abdominal surgery (n=91), a single intravenous infusion of ceruletide (2.5 ng kg−’min−1’for 1 hour) resulted in audible bowel sounds in 42/47 patients as opposed to 30/44 receiving placebo (P 〈 0.025). Excessive bowel sounds were noted in 16 patients in the ceruletide group and four receiving placebo (P 〈 0.01). Significantly more patients (P 〈 0.01) in the ceruletide group (22/45 versus 9/44) passed flatus per rectum between the second and third post-operative day. Ceruletide infusion was accompanied by a significant increase in the incidence of nausea and vomiting (P 〈 0.005, P 〈 0.0025) but these side effects were short-lived. These results indicate that ceruletide is likely to be a useful therapeutic agent for acute intestinal adynamic motility disorders.

    Description / Table of Contents: Résumé Les auteurs décrivent une technique particulière de cholédoco-duodénotomie qui consiste en la section transversale de la voie biliaire principale au niveau de son passage en arriére du pancréas et la constitution d'une anastomose cholédoco-duodénale terminolatérale. Ce type d'opération a été réalisé chez 46 malades au cours d'une période supérieure à 14 ans, 26 opérés ayant été suivis plus de 5 ans. Aucun cas de sténose postopératoire de l'anastomose n'a été constaté. Un malade seulement a présenté un épisode ictérique 3 ans après l'intervention.
    Abstract: Resumen Se describe una técnica de coledocoduodenostomía que implica la transección del canal colédoco a nivel de su unión con el segmento trans-pancreático y anastomosis término-terminal con el duodeno. La operación ha sido realizada en 46 pacientes sobre un período de 14 años, con 26 pacientes seguidos por períodos de 5 años o más. No se ha presentado caso alguno de estenosis anastomótica en la serie, aun cuando un paciente tuvo un episodio único de ictericia 3 años después de la operación.
    Notes: Abstract A technique of choledochoduodenostomy involving transection of the bile duct at its junction with the trans-pancreatic segment and an end-to-side anastomosis with the duodenum is described. The operation has been performed in 46 patients over a period of 14 years, 26 patients having had a follow-up of 5 years or more. There has been no instance of anastomotic stenosis in the series, although one patient had a single episode of jaundice 3 years after operation.

    Computerized gnomonic projection chart for determining orientations of single crystals from Kossel patterns (1970)

    Notes: The increasing use of the electron microprobe analyser in research laboratories in recent years renewed the interest in the Kossel line method. Since it is possible to obtain diffraction patterns from selected areas – smaller than 5 microns diameter – this technique has been applied to measure the grain orientation in polycrystalline materials. Comparing the different published methods of interpreting the Kossel patterns, it has been found more convenient to use a digital computer with a peripheral graph plotter to obtain charts.
