    Notes: Abstract A total of 450 yeast isolates were obtained from up to 34 sites on 59 human subjects. The yeasts were characterized using morphological features and assimilation tests. Ten species were identified but, of these,Candida albicans andCandida parapsilosis were the most common and accounted for 84% of the isolates. An examination of the biotypes of the various species indicated a much greater diversity in the yeast microflora than that detected by species identifications alone. Fifty-five biotypes were differentiated and it is suggested that these could be regarded as distinct taxonomic or ecological entities.

    Characterization of the PVC phenomena in the exhaust of a cyclone dust separator (1994)

    Notes: Abstract A laboratory scale cyclone dust separator with swirl numbers varying from 3.043 to 1.790 was used to examine the effects of different downstream pipework configurations, flowrates and swirl numbers upon the size, shape, and position of the precessing vortex core. Also examined was the effect the precessing vortex core had on the reverse flow zone, and the relationship between the two. It was concluded that the reverse flow zone displaced the central vortex core to create the precessing vortex core. The reverse flow zone would then provide feedback for the precessing vortex core, and precess around the central axis about 30 degrees behind the precessing vortex core (P.V.C). The size and position of the P.V.C was effected by changes in Reynolds number, and any additions of downstream systems to the cyclone would also affect the strength of the P.V.C. The P.V.C would squeeze and accelerate the flow through a constriction set up between the outer limits of the core and of the exit diameter wall. Spiral engulfment vortices were produced on the outside of the flow and served as the initial entrainment mechanism for external flow.

    Notes: Abstract   We have determined the complete nucleotide sequence of a linear mitochondrial plasmid from a natural isolate of a homothallic species of Gelasinospora. The plasmid genome is 8231 bp long. It carries terminal inverted repeats of 1137 bp. Extending inwards from the terminal repeats are two long open reading frames coding for putative proteins with similarity to DNA and RNA polymerases. These are separated by a short intergenic region. The plasmid sequence shows remarkable similarity to that of the Neurospora intermedia senescence-plasmid kalilo. Overall the two plasmids have a similar genetic organization and are clearly homologous at the sequence level. The main differences are in the intergenic region and in the terminal repeats.

    Notes: Two studies of the communication skills of orally educated deaf primary school children are repotted. In the first, a referential communication task with very limited linguistic demands, severely and profoundly deaf children performed as well us a hearing control group. In the second task with a richer linguistic domain. differences m performance were found between deaf children from three schools with different linguistic philosophies, children from the school performing com-parably to hearing children, those from the other two schools slightly worse. It is concluded that deaf children are more able communicators than their grammatical competence suggests.

    THE STRUCTURE OF CONVERSATIONS WITH 6- TO 10-YEAR-OLD DEAF CHILDREN (1982)

    Notes: In stage 1 classroom conversations between sixteen teachers and their pre-lingually deaf children were videotaped and analysed to examine both the styles used by teachers in controlling conversation and the functions pursued in dialogue. In stage 2 a sub-sample of four teachers with twenty children of known hearing losses and non-verbal intelligence was analysed in greater detail to examine relationships between these factors, teaching styles and the child's performance in dialogue. The analyses show that deaf children respond in a similar fashion to young hearing children in the way they react to different styles of teacher talk; that teachers differ in the functions they pursue in conversation; and that functions change as a consequence of the child's hearing loss but not mental age. The implications of the findings for linguistic development in pre-lingually deaf children are explored.

    The Physiology of Encystment of Hartmannella castellanii (1969)

    The @journal of eukaryotic microbiology 16 (1969), S. 0 
    Details

    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Biology
    Notes: SYNOPSIS. Some aspects of the physiology of encystment of the soil amoeba Hartmannella castellanii in a replacement encystment medium consisting of 5 × 10-2 M MgCl2 have been investigated. It is suggested that measurement of the cellulose produced during encystment in the synthesis of the cyst wall is a more reliable measure of the process than other methods tried.The degree of encystment was dependent on the physiologic state of the amoebae and the composition of the growth medium, but the initial pH of the encystment medium (C. 4.0-8.5) had little effect on the process. The requirement for Mg during encystment was probably not due to its deficiency during growth. Encystment was inhibited to varying extents by inhibitors of protein synthesis, tetracycline and chloramphenicol and also by arsenate, arsenite and iodoacetate; sodium fluoride, malonate and 2, 4-dinitrophenol were without marked effect.Addition of glucose and α-ketoglutarate to the replacement medium led to improvement in the encystment response. The presence of glutamate and histidine during encystment led to cell death. Other carbon and nitrogen sources had no effect.During encystment there was an increase in the metabolic activity of the amoebae, as measured by their oxygen consumption. This was accompanied by a decrease of about 40% in cellular dry weight and protein content. Of the other chemical components, there were marked initial increases in the levels of total carbohydrates and pentose which were followed by their depletion during cellulose synthesis.Encystment was completed after about 64 hr when the synthesis of cellulose was complete and the oxygen uptake of the amoebae fell to an immeasurable level.

    Starvation and Encystment of a Soil Amoeba Hartmannella castellanii (1968)

    Notes: SYNOPSIS. The behavior of the amoeba H. castellanii was investigated in various carbon and nitrogen deficient media with a view to developing a satisfactory replacement medium for the study of encystment and excystment. Media which had been devised for other soil amoebae did not cause H. castellanii to encyst. In these media there was an efflux of material from the cells which was independent of osmolarity but which was minimized by the addition of magnesium. Maximal encystment occurred in a medium containing magnesium chloride alone.The cysts produced in the magnesium chloride replacement medium are viable and readily excyst when resuspended in the growth medium. The cysts contain cellulose, which is not present in the vegetative amoebae, and differ from the amoebae in their greater resistance to induced lysis and mechanical injury.
