    Notes: Summary The paper is concerned with the investigation of the magneto-elastic waves and disturbances in initially stressed conducting media. Firstly, (a) the steady state response to moving loads in a magneto-elastic initially stressed conducting medium under an uniaxial tension has been discussed. Secondly, (b) the Lamb's problem corresponding to a line load suddenly applied in a magneto-elastic initially stressed conducting half-space bounded by a plane under uniaxial tension has been investigated. The final results obtained in both cases are in agreement with the corresponding classical problems when the initial tension is zero and the magnetic field is absent.

    Notes: Résumé La dépression induite par l'uréthane sur la respiration des mitochondries a été mesurée en présence de la vitamin E (α-tocophérol). Ces agents furent utilisés in vitro et aussi injectés intrapéritonellement. Nos résultats montrent que l'apport de vitamine enraye la diminution de la respiration causée par l'uréthane. Ils attestent le rôle que joue l'uréthane dans la carcinogénèse et la necessité de poursuivre ces expériences sur une plus grande échelle.

    Notes: Abstract Single crystals of MgO have been heated with crystals of Al2O3, Fe2O3 and TiO2 on cut and polished faces, in known relative crystallographic orientations. The initial product in every case was a spinel phase witha 0=8.38 Å, oriented with its axes parallel to those of MgO. Crystals reacted in different orientations gave the same product, but kinetic rates appeared to differ. CaO and TiO2 crystals, treated in the same way, gave an unoriented product.

    Notes: Summary The prd gene, the mutant allele of which permits growth of E. coli on 1,2-propanediol as sole carbon source, has been located by transduction very close to the rel (RNA control) gene. This close linkage provides a convenient means for the inter-strain transfer of rel.

    Description / Table of Contents: Résumé L'activité de l'oxyclozanide a été étudiée chez les buffles, les bovins, les moutons et les chèvres naturellement infestés parF. gigantica. Les résultats révèlent une trés haute efficacité contre les douves âgées de six semaines ou plus. Ce produit se montra aussi très actif sur les amphistomes du foie et du rumen. Aucun effet toxique associé ne fut observé chez les animaux traités, excepté un léger ramollissement des fèces, un accroissement de la fréquence des défécations et de l'inappétence chez un petit nombre d'animaux. Cela fut observé plus souvent chez les buffles que chez les bovins. Chèves et moutons furent moins affectés. On observa chez quelques animaux une baisse temporaire de la production lactée durant deux à trois jours. Aucune réaction défavorable n'apparut chez les animaux d'expérience soumis à régime à forte teneur en azote. Le produit est aussi bien toléré par les femelles en gestation.
    Abstract: Sumario Se estudió la actividad del oxyclozanide en búfalos, bovinos, ovinos y caprinos infectados naturalmente conFasciola gigantica. Los resultados indican una eficiencia muy alta contra Fasciolas de 6 semanas ó mas. La droga tuvo también una acción considerable sobre los amfistomas hepáticos y ruminales. No se observaron efectos colaterales tóxicos en los animales tratados, excepto por el ligero ablandamiento de las heces con un incremento de la frecuencia en la defecación e inapetencia en algunos animales. Esto se observó mas frecuentemente en búfalos que en bovinos. Los ovinos y caprinos fueron menos afectados. Se observó una disminución transitoria en la producción de leche de algunos animales la cual duró de dos a tres dias. No se observaron efectos nocivos en los animales en experimentación que fueron mantenidos con dietas altas en nitrógeno. La droga fué tolerada bastante bien por animales en gestación.
    Notes: Summary The activity of oxyclozanide was studied in buffalo, cattle, sheep and goats naturally infected withFasciola gigantica. The results indicate a very high efficiency against flukes aged six weeks or more. The drug was also observed to have considerable action on hepatic and ruminal amphistomes. No toxic side-effects were observed in any of the animals treated, except slight softening of faeces with increased frequency of defaecation and inappetance in a few animals. This was observed more frequently in buffalo than in cattle. Sheep and goats were less affected. A transient drop in milk yield for about two to three days was observed in a few animals. No ill effects were observed in experimental animals which were maintained on highly nitrogenous diets. The drug was also well-tolerated by pregnant animals.

    Notes: In the genus Momordica three species M. charantia, M. balsamina and M. dioica, have been cytologically investigated. M. dioica has a more asymmetrical karyotype than the other two species. Meiosis in the three species is regular. The strictly monoecious M. charantia and M. balsamina show similarity in the range and frequency of bivalents and chiasmata, whereas M. dioica, a dioecious species, has fewer half chiasmata per chromosome. The evolutionary significance of perennial and annual habits along with allogamous and autogamous breeding systems is discussed. The incompatibility between 2n=22 and 2n=28 species in this genus is strongly indicated by the negative results of crossings between M. charantia and M. balsamina on one side and M. dioica on the other. The possible origin of M. dioica from M. charantia is discussed.

    Notes: Abstract In two interspecific hybrids of Luffa, i.e., L. acutangula x L. graveolens and L. echinata x L. graveolens, various types of chromosome associations, from univalents to quadrivalents were observed. The hydrid L. echinata x L. graveolens showed a much higher frequency of univalents than the other hybrid, but the pairing data of both indicate partial homology among most of the chromosomes of the three species. The study of these F1 hybrids has been utilised for establishing the phylogenetic relationship among the various species and to trace the trend of evolution in the genus Luffa. The two wild species, L. graveolens and L. echinata, are closely related, whereas, L. graveolens is more distantly related to L. acutangula than to L. echinata. It has also been concluded that dioecism in L. echinata is a derived feature, established after diverging from the monoecious prime species L. graveolens.

    Notes: Abstract By a systematic variation of the crystal-chemical parameters, we have found a new family of photoconducting-materials that are glassy oxides containing no variable valency ions. The “best” compositions group around the general formula 65 MO-20 R2O3-15 XO2. Electronic conduction and near-ohmic behaviour are established. The spectral response shows a peak at 380 nm corresponding to the absorption edge of the glass. Very small (∼10 ppm) concentrations of impurities nearly destroy the photo effects. A conduction model based on Goodenough's d-orbital overlap is presented to account for the data.
