    Loop-wire medium for investigating plasmons at microwave frequencies (1999)

    Notes: We present numerical simulations and microwave measurements on a loop-wire structure that acts as an effective medium exhibiting a well-defined bulk plasma frequency in the microwave regime, with an effective negative dielectric function below this plasma frequency. The dependence of this plasmonic response on the self-inductance of the constituent wire elements is made explicit. A finite structure, approximately spherical, composed of this inductive medium is studied, and reveals subwavelength surface plasmon resonances below the bulk plasma frequency. © 1999 American Institute of Physics.

    Pathogenicity of A and B morphotypes of Sphaeropsis sapinea confirmed on American larch (tamarack) and European larch (1997)

    Notes: Fungi identified as Sphaeropsis sapinea (or synonyms) have been reported from Larix. Lack of pathogenicity tests, confusion about the identity of isolates mentioned in previous literature, and existence of distinct populations (A and B morphotypes) of the pathogen indicated the need to evaluate the ability of S. sapinea to cause disease of larch. Elongating snoot tips of Larix decidua, Larix laricina, and known hosts of the pathogen, Pinus banksiana and Pinus resinosa, were inoculated with water-agar plugs colonized with an A or a B isolate, or sterile plugs (controls). Each of five replications included five seedlings for each treatment-species combination. After 6 weeks, no symptoms had developed on control seedlings, but two-way analyses of variance revealed significant effects of isolate morpnotype and host on both incidence and severity of disease (values of p ≤ 0.01). The A isolate killed almost all shoot tips, but the B isolate killed from no P. resinosa shoots to 56% of L. laricina shoots. The average length of shoot killed by the A isolate was also greater than that killed by the B isolate. Response to the B isolate again varied among species, with greater average lengths of shoot killed on the larches (compared with the pines). Both A and B morphotypes of 5. sapinea should be considered among the fungi encountered on L. decidua and L. laricina.

    Similarity between fungi identified as Diplodia pinea f. sp. cupressi in Israel and Botryosphaeria stevensii or Diplodia mutila on Juniperus in the United States (1998)

    Notes: A fungus identified as Botryosphaeria stevensii (anamorph Diplodia mutila) causes a canker disease that results in dieback of Juniperus species in the United States. A fungus identified as Diplodia pinea f. sp. cupressi causes a similar disease of Cupressus species in Israel and elsewhere. Cultural characteristics, pycnidia, and conidia of isolates of these two pathogens were compared. The ability of each fungus to produce cankers on Cupressus sempervirens was tested. Random amplified polymorphic DNA (RAPD) marker patterns also were analysed, using Sphaeropsis sapinea (syn. Diplodia pinea) isolates as an outgroup. Results indicate the fungus identified as D. pinea f. sp. cupressi from cypress in Israel is the same as, or at least highly similar to, the fungus identified as B. stevensii (or D. mutila) from juniper in the United States. Analysis of RAPD markers indicates relatively low similarity between these isolates and those of S. sapinea. Because these results are consistent with a previously published report describing substantial morphological and isozyme differences between isolates identified as D. pinea f. sp. cupressi and those of S. sapinea, use of the name D. pinea f. sp. cupressi should be abandoned. Inconsistencies between these isolates from juniper and cypress and published descriptions of B. stevensii and D. mutila, however, indicate the need for additional investigation into the relationship of these fungi.

    The tentorial artery: Its diagnostic significance (1969)

    Description / Table of Contents: Zusammenfassung Anatomie, radiographische Darstellung und pathologische Bedeutung der tentoriellen Arterie, die ein Ast der kavernösen Verlaufsstrecke der A. carotis interna ist, werden besprochen. Es werden 18 Patienten mit verbreiterter tentorieller Arterie beschrieben. Es handelte sich dabei mit fast gleicher Häufigkeit um Tentorium-Meningeome (4), maligne Gliome (6) und arteriovenöse Mißbildungen (4). Zusätzlich fand sich ein einzelner Fall, in dem dieses Gefäß ein Akustikusneurinom versorgte; eine solche Beziehung ist bisher noch nicht beschrieben worden. In drei Fällen stand die erweiterte Arterie in keinem erkennbaren Zusammenhang zu der bestehenden Erkrankung.
    Abstract: Résumé Les auteurs ont étudié l'anatomie, la visualisation radiographique et la signification pathologique de l'artère de la tente, branche de la portion caverneuse de la carotide interne. Dix huit patients ont présenté une artère tentorielle élargie: 4 cas de méningiome de la tente, 6 cas de glioblastome, 4 cas d'angiome, 1 cas de neurinome du VIII, vascularisé par l'artère tentorielle (ceci n'a pas été décrit auparavant). Dans les trois derniers cas, l'élargissement de l'artère tentorielle n'était pas formellement en rapport avec la lésion présente.
    Notes: Summary The anatomy, radiographic visualization and pathological significance of the tentorial artery, which is a branch of the cavernous portion of the internal carotid artery, is discussed. Eighteen patients with an enlarged tentorial artery are described. The diagnoses in these patients were almost equally divided among tentorial meningiomas (4), malignant gliomas (6) and arteriovenous malformations (4). In addition there was a single case in which this vessel fed an acoustic neuroma; this relationship has not been previously reported. In three cases the enlarged artery was not recognizably related to the lesion present.

    A study of the effects of curvature and compression on the behavior of a supersonic turbulent boundary layer (1995)

    Notes: Abstract The influences of concave streamline curvature and bulk compression on a turbulent boundary layer in a supersonic flow were studied. The effects of curvature and compression were identified by comparing two flows with identical pressure distributions but different amounts of curvature. The effect of the pressure rise was to increase the wall stress and amplify the Reynolds stresses. The influence of curvature complemented the destabilizing effect of the compression, and the larger the curvature the greater the increase in the wall friction and Reynolds stresses in the boundary layer.

    Notes: Abstract A biolistic particle delivery system was used to genetically transform embryogenic tissue of Pinus radiata. The introduced DNA contained a uidA reporter gene under the control of either the tandem CaMV 35S or the artificial Emu promoter, and the npt II selectable marker controlled by the CaMV 35S promoter. The average number of stable, geneticin-resistant lines recovered was 0.5 per 200 mg fresh weight bombarded tissue. Expression of the uidA reporter gene was detected histochemically and fluorimetrically in transformed embryogenic tissue and in derived mature somatic embryos and regenerated plants. The integration of uidA and npt II genes into the Pinus radiata genome was demonstrated using PCR amplification of the inserts and Southern hybridisation analysis. The expression of both genes in transformed tissue was confirmed by Northern hybridisation analysis. More than 150 transgenic Pinus radiata plants were produced from 20 independent transformation experiments with four different embryogenic clones.

    Experimental inoculation of adult dairy cows with bovine coronavirus and detection of coronavirus in feces by RT-PCR (1999)

    Notes: Summary.  A reverse transcriptase PCR (RT-PCR) targeting a 407 bp fragment of the nucleocapsid gene of bovine coronavirus (BCV) was developed for detection of BCV RNA in feces of experimentally inoculated cattle. The sensitivity and specificity of the RT-PCR were confirmed using tissue culture-adapted BCV strains and feces of 2 calves inoculated with BCV. Ten nonpregant, BCV seropositive, adult dairy cows were inoculated with winter dysentery (WD) (n = 8) or calf diarrhea (CD) (n = 2) strains of BCV intranasally and orally (n = 2) or through a surgically-placed duodenal catheter (n = 8) with and without dexamethasone treatment or feeding ice water. The 6 cows inoculated with BCV intranasally and through a duodenal catheter (2 of 2 cows given CD BCV and 4 of 6 cows given WD BCV) developed mild diarrhea, and BCV was detected in diarrheal feces by RT-PCR, ELISA or immune electron microscopy. These results suggest that CD and WD strains of BCV can cause diarrhea in adult cows in conjunction with host or environmental factors and that RT-PCR might be useful to diagnose BCV infections in calves and adult cows.
