    Notes: Summary Acidogenesis and solventogenesis byClostridium beijerinckii NRRL B-593 has been studied in batch growth, and in sucrose-limited chemostat and recycling fermentor growth. Cells grown in batch culture without pH control primarily produced either butyric and acetic acids, or these acids plus butanol, ethanol and isopropanol in ratios depending on the medium's content of reducing agent, calcium and iron. Cells in chemostat-culture at a mass doubling time (td) of 5.8 h produced primarily butyric and acetic acids at pH 6.8 and these acids plus butanol, ethanol and isopropanol at pH 4.8. Cells grown in a recycling fermentor (in which the td continuously increases) at pH 6.8 entered solventogenesis at a td of 43 h, producing primarily propanol, ethanol and butanol, along with butyric acid, but with greatly decreased production of acetic acid. Although “clostridial form” morphology, succeeded by sporulation, usually accompanied solventogenesis, the association was not invariant so that solventogenesis and sporogenesis can occur separately in this species.

    Description / Table of Contents: Résumé On sait que la pleuropneumonie du mouton et de la chèvre cause de sérieuses pertes économiques dans beaucoup de pays, dont l'Arabie Saoudite. Une recherche préliminaire a été entreprise sur 163 chèvres et 130 moutons montrant des symptômes cliniques ou des lésions à l'autopsie. Des prélèvements du tractus respiratoire de chèvres et de moutons vivants ou abattus (respectivement 183 et 160 échantillons) ont été mis en culture pour la recherche de mycoplasmes. Sur les 343 cultures de mycoplasmes examinées, 211 souches (soit 61,5%) ont été caractérisées au point de vue biochimique. 116 souches ont pu être identifiées sérologiquement comme étantM. mycoides sub.mycoides, M. ovipneumoniae, M. conjunctivae, M. agalactiae sub.agalactiae, M. putrefaciens etM. arginini. Les autres souches de mycoplasmes n'ont pas été identifiées. La signification des souches identifiées et leur effet pathogène probable sur le tractus respiratoire des chèvres et des moutons sont discutés. Leur pouvoir pathogène demande à être expérimentalement établi avant de mettre en place un programme de contrôle de la maladie dans le Royaume.
    Abstract: Resumen Se llevó a cabo una investigación preliminar en 163 cabras y 130 ovejas las cuales mostraron síntomas clínicos o lesiones postmortem de pleuroneumonía contagiosa. Se cultivaron en medios especiales muestras patológicas del tracto respiratorio de cabras y ovejas vivas (183 y 160 muestras respectivamente. De 343 cultivos examinados, 211 (61·5%) aislamientos se caracterizaron bioquímicamente. Un total de 116 aislamientos se caracterizaron serológicamente comoM. mycoides, subsp.mycoides, M. ovipneumonia, M. conjuntivae, M. agalactiae subsp.agalactiae, M. putrifaciens yM. arginini. Los restantes micoplasmas aislados no fueron identificados. Se discute el significado de los aislamientos identificados y su posible efecto patógeno en el tracto respiratorio de cabras y ovejas. Es necesario establecer la patogenicidad experimentalmente antes de iniciar un programa de control en el Reino.
    Notes: Summary Pleuropneumonia of goats and sheep has been known to cause serious economic losses in many countries including Saudi Arabia. A preliminary investigation was carried out on 163 goats and 130 sheep which showed clinical symptoms or post-mortem lesions of pleuropneumonia. Pathological samples from the respiratory tract of live or slaughtered goats and sheep (183 and 160 samples respectively) were cultured for mycoplasmas. Of 343 mycoplasma cultures examined 211 (61·5%) isolates were characterised biochemically. A total of 116 isolates were serologically identified asM. mycoides subsp.mycoides, M. ovipneumonia, M. conjunctivae, M. agalactiae subsp.agalactiae, M. putrifaciens andM. arginini. The remaining mycoplasma isolates were not identified. The significance of the identified isolates and their probable pathogenic effect on the respiratory tract of goats and sheep are discussed. Their pathogenicity needs to be established experimentally before initiating a control programme in the Kingdom.

    Description / Table of Contents: Summary A description and a review of the Hilbert transform procedures for detecting and quantifying structural non-linearity in frequency response functions obtained during modal testing is presented in this paper. A method of minimizing the effect of residual modes of vibration, previously a problem with the numerical Hilbert transform, is also described.
    Notes: Sommario Si descrivono e si riesaminano le procedure di trasformazione Hilbert per la scoperta e la quantificazione della non linearità strutturale nelle funzioni di risposta alla frequenza ottenute durante le prove modali. Si descrive anche un metodo per minimizzare l'effetto dei modi residui di vibrazione, già problematico per quanto riguarda la trasformazione numerica Hilbert.

    Description / Table of Contents: Résumé L'efficacité de l'oxytétracycline (OTC) seule ou combinée à la streptomycine pour traiter 118 brebis Najdi supposées avoir été naturellement infectées parBrucella melitensis, a été évaluée lors de l'abattage par la mise en culture de tissus et d'organes sélectionnés. Des groupes de moutons ont reçu 250, 500 ou 1000 mg d'OTC par voie intrapéritonéale (i/p) tous les jours pendant six semaines; à l'autopsie, on a trouvé respectivement 52, 69 et 100% des moutons libres de Brucella. Le traitement avec 250 mg d'OCT (quotidiennement pendant six semaines, i/p) combiné à 1000 mg de streptomycine (quotidiennement pendant trois semaines par voie intramusculaire) a augmenté le pourcentage de moutons sans Brucella à 82%. En inoculant un groupe de moutons recevant chacun 1000 mg d'OTC à longue action par voie i/p tous les trois jours pendant une période de six semaines, 75% d'entre eux ont été trouvés libres deBrucella à l'autopsie.B. melitensis a été isolé de tous (24) moutons non traités (contrôlés). Les résultats montrent qu'un traitement à long terme avec l'OTC seule à haute dose a permis d'éliminerB. melitensis d'un groupe de 16 moutons naturellement infectés.
    Abstract: Resumen Se evaluó la eficacia de la oxitetraciclina (OTC) sola o en combinación con estreptomicina, en el tratamiento de 118 ovejas Najdi, infectadas naturalmente conBrucella melitensis. Cultivos selectivos de diferentes órganos en le matadero, sirvieron como base de evaluacióh del tratamiento antibiótico. Los diferentes grupos de ovejas se inyectaron con 250, 500 o 1000 mg de OTC vía intraperitoneal (i/p) diariamente, durante seis semanas y en los grupos respectivos a la necropsia se encontraron libres de brucelosis 52, 69 y 100% respectivamente. El tratamiento con 250 mg de OTC (diario por seis semanas i/p), combinado con 1000 mg de estreptomicina (diario por tres semanas intramuscular), incrementó el porcentaje de animales libres de brucelosis a un 82%. Cuando un grupo de ovejas fueron inoculadas cada una i/p con 1000 mg de oxitetraciclina LA, cada tres días por un período de seis semanas, 75% de ellas se encontraron libres de brucelosis a la necropsia. Se aislóB. melitensis de todos los controles (24) no tratados. Los resultados demuestran, que el tratamiento prolongado con una dosis alta de OTC solamente, ha sido exitoso en eliminarB. melitensis de un grupo de 16 ovejas naturalmente infectadas.
    Notes: Summary The efficacy of oxytetracycline (OTC) alone or combined with streptomycin in the treatment of 118 Najdi ewes believed to have been naturally infected withBrucella melitensis, was evaluated by culture of selected tissues and organs at slaughter. Groups of sheep were given 250, 500 or 1,000 mg of OTC intraperitoneally (i/p) daily for six weeks and in the respective groups at necropsy 52, 69 and 100% of sheep were found to beBrucella-free. Treatment with 250 mg OTC (daily for six weeks i/p) combined with 1,000 mg streptomycin (daily for three weeks intramuscularly) increased the percentage ofBrucella-free sheep to 82%. When a group of sheep were each inoculated i/p with 1,000 mg of long-acting OTC every three days over a period of six weeks, 75% of them wereBrucella-free at necropsy.B. melitensis was isolated from all (24) non-treated (control) sheep. The results showed that long-term treatment with a high dose of OTC alone had succeeded in eliminatingB. melitensis from a group of 16 naturally infected sheep.

    Notes: Quantitative and qualitative IR analysis of some synthesized aromatic homo polysulfides and copolysulfides based on 4,4-oxydibenzenethiol (IV), 4,4-dimercaptodiphenyl sulfide (I) and bis-(4-fluorophenyl) Sulfone (II) in 1-methyl-2-pyrrolidone (NMP) has been done. A satisfactory agreement of experimental results with theory was observed.
