    Notes: This article presents a Monte Carlo approach to simulate the dispersive transport of holes/H+ ions in silicon-dioxide using simplified formalism of continuous time random walk theory given by Montroll and Scher [E. W. Montroll and H. Scher, J. Stat. Phys. 9, 101 (1973); H. Scher and E. W. Montroll, Phys. Rev. B 12, 2455 (1975)]. It has been shown that the simulated results of this approach match quite well with the theoretical predictions for a value of dispersion coefficient, α, =0.5 which validates our Monte Carlo simulator. We have used this simulator to resolve the memory effect observed by Saks et al. [N. S. Saks, D. B. Brown, and R. W. Rendell, IEEE Trans. Nucl. Sci. 38, 1130 (1991)] in their simulations of switched gate bias experiments in context with the hydrogen ion transport model for the buildup of radiation-induced interface states. We have accounted for the memory effect, which is related with the dwell time of an ion at the last hopping site just before field switching, by treating the first hop after field switching differently from all other hops. We have shown that the memory effect can be incorporated by modifying the value of α only for the first hop after field switching depending on the dwell time at the last hopping site just before field switching. We have found that a logarithmic relationship between the two gives a very good match between the simulated and the experimental results of half-time (the time required to build 50% of saturated interface states) versus time of field switching, tswitch, relationship. © 1998 American Institute of Physics.

    Description / Table of Contents: Résumé Etude de 17 patients, le plus jeune âgé de 7 mois et le plus vieux de 20 ans porteurs d'une ostéomyélite hématogène avec grande séquestration diaphysaire. L'incorporation du séquestre diaphysaire sera finalement obtenue dans tous les cas. Nous pensons que l'ostéomyélite hématogène chronique avec séquestration diaphysaire doit être traitée avec une intervention chirurgicale à minima sous forme d'incision et de drainage et d'un traitement antibiotique (de 6 à 8 semaines initialement et éventuellement répété selon l'évolution) et d'une immobilisation plâtrée de longue durée. L'indication de séquestrectomie sera posée seulement si la surveillance radiologique ne montre pas de réduction en taille du séquestre et une augmentation de l'involucrum.
    Notes: Summary Seventeen patients with haematogenous osteomyelitis and long diaphyseal sequestra are reported. Treatment was incision and drainage with antibiotics for at least 6 to 8 weeks, the limb being protected in plaster for a long time. The sequestra became incorporated in every case. Sequestrectomy should only be undertaken when successive radiographs show no reduction in size of the sequestrum and an increase in the amount of the involucrum.

    Description / Table of Contents: Résumé Une épidémie d'hémoglobinurie bacillaire a été rapportée chez 60 sur 110 moutons à Ludhiana Punjab, Inde. L'état cliniques des animaux était caractérisé par de la fièvre, de l'hémoglobinurie, de la constipation, une faiblesse de l'arrière train suivie de décubitus, de détresse respiratoire et de mort chez 16 moutons. Des études hématologiques ont révélé des degrés d'anémie modérés à graves associés à de la leucocytose. Les activités de phosphokinase créatinine et phosphatase alcaline et gamma-glutonyl transferase du plasma ont été significativement plus élevées chez les moutons hémoglobinuriques. Une babésiose et une intoxication au cuivre ont été écartées respectivement à l'examen d'un frottis de sang coloré et des profils minéraux du sang. L'examen post mortem des moutons atteints n'a pas révélé de modifications importantes. Des cultures pures deClostridium haemolyticum isolé du sang du coeur, du foie, des reins et de la rate de moutons récemment abattus ont confirmé la maladie. L'administration parentérale de pénicilline procaïne a traité efficacement les moutons atteints.
    Abstract: Resumen Ocurrió un brote de hemoglobinuria bacilar en 60 de 110 ovejas en Ludhiana, Punjab, India. La condición se caracterizó por fiebre, bemoglobinuria, constipación, debilidad del tren posterior, seguido de postración, dispnea y muerte en 16 ovejas. Análisis hematológicos mostraron anemia moderada a severa asociada con leucocitosis. La actividad de gamma-glutonyl transferasa, fosfatasa alcalina y creatinina-fosfoquinasa en el plasma fué significativamente mayor en las ovejas hemoglobinúricas. Se descartó babesiosis y envenenamiento por cobre mediante examen de frotis sanguineo y perfiles sanguíneos de minerales, respectivamente. El examen post-mortem de las ovejas afectadas no mostró cambios macroscópicos. Se aislóClostridium haemolyticum de cultivos puros de corazón, sangre, higado, riñón y bazo de ovejas recién sacrificadas, lo cual confirmó la enfermedad. La administración parenteral de penicilina procainica fué efectiva en el tratamiento de las ovejas enfermas.
    Notes: Summary An outbreak of bacillary haemoglobinuria was recorded in 60 out of 110 sheep in Ludhiana, Punjab, India. The condition was clinically characterised by fever, haemoglobinuria, constipation, weakness of hind quarters followed by recumbency, respiratory distress and death in 16 sheep. Haematological studies revealed moderate to severe degrees of anaemia associated with leucocytosis. Plasma gamma-glutamyl transferase, alkaline phosphatase and creatinine phosphokinase activities were significantly higher in haemoglobinuric sheep. Babesiosis and copper poisoning were ruled out on stained blood film examination and from blood mineral profiles, respectively. Post-mortem examination of affected sheep revealed no gross changes. Pure cultures ofClostridium haemolyticum isolated from heart blood, liver, kidney and spleen of freshly killed sheep confirmed the disease. Parenteral administration of procaine penicillin was effective in the treatment of affected sheep.
