    STUDIES IN THE DIGESTIBILITY OF HERBAGE (1961)
    Oxford, UK : Blackwell Publishing Ltd
    Grass and forage science 16 (1961), S. 0 
    Details

    Notizen: Data from 291 digestion trials have been used to derive regression equations relating the organic-matter digestibility of herbage to the nitrogen percentage of its dry matter and to the nitrogen percentage in the organic matter of the resulting faces.The residual errors are very high and it is shown that the deviations from the lines are not randomly distributed but have a seasonal trend. The seasonal biases have been calculated, and the inclusion of month of cutting as a factor is found to improve the two regressions to some extent. Monthly regressions have also been calculated. Even with these, however, the errors are still too high for many practical purposes.

    Effect of Storage Temperature, Equilibration Time, and Buffers on Survival of Tritrichomonas foetus in the Presence of Glycerol at Freezing Temperatures (1961)
    Oxford, UK : Blackwell Publishing Ltd
    The @journal of eukaryotic microbiology 8 (1961), S. 0 
    Details
    ISSN: 1550-7408
    Quelle: Blackwell Publishing Journal Backfiles 1879-2005
    Thema: Biologie
    Notizen: Tritrichomonas foetus survives when frozen in the presence of 1 M glycerol after growth in cysteine-peptone-liver-maltose (CPLM) medium. In the present study, survival upon storage was better in a chest-type freezer at a constant −21°C than in an upright freezer from which were recorded cyclic temperature fluctuations between −23 and −25° or in a dry-ice chest with a nominal temperature of −72°. By the use of special thermocouples inside the freezing tubes, it was found that the temperature fluctuated between −22 and −24° in the chest-type freezer, between −19 and −30° in the upright freezer, but rising as high as -2° when the door was opened and samples were removed, and markedly in the dry-ice chest as the dry ice melted and was replaced, sometimes rising to as high as −27°. The poorer survival in the latter 2 freezers was considered due to temperature fluctuation.When equilibration with glycerol was carried out at room temperature, survival upon subsequent freezing was better following rapid equilibration (glycerol added all at once; equilibration time, 1 hour) than following slow equilibration (1/6 of the final amount of glycerol added each hour for 6 hr.; equilibration time, 7 hr.).Survival was extremely poor following either rapid or slow equilibration in the refrigerator (4°). Since T. foetus can grow indefinitely at 37° in the presence of 10% glycerol and since it is protected by glycerol when frozen, there is a critical zone near 4° in which glycerol appears to be toxic.Buffering the storage medium to pH's 6.3 to 7.1 with glycyl-glycine increased survival upon freezing, but buffering to the same pH's with triethanolamine had no significant effect upon survival, and buffering to pH's 7.1 to 7.5 with phosphates decreased survival upon freezing.

    Characterization and Distribution of “H” Serotypes in 25°C Cultures of Tetrahymena pyriformis, Variety 1. (1961)
    Oxford, UK : Blackwell Publishing Ltd
    The @journal of eukaryotic microbiology 8 (1961), S. 0 
    Details
    ISSN: 1550-7408
    Quelle: Blackwell Publishing Journal Backfiles 1879-2005
    Thema: Biologie
    Notizen: A survey of antigenic types, as revealed by immobilization reactions, among 78 strains of variety 1 of T. pyriformis grown in monoxenic cultures at 25°C discloses a minimum of six distinct classes. These are called the H serotypes, and are designated as types Ha, Hb, Hc, Hd, He and Hf. The terminal members of highly inbred series (Families A, A1, B, D, etc.) are of a single immunological class, but different inbred series show different serotypes. Early representatives of the inbred series show in contrast considerable serotypic variation. The distribution of serotypes is generally consistent with the genetic hypothesis developed in a parallel study, but new serotypes arise occasionally through some mechanism not yet adequately studied.

    Problems in the Systematics of the “Sporozoa” (1961)
    Oxford, UK : Blackwell Publishing Ltd
    The @journal of eukaryotic microbiology 8 (1961), S. 0 
    Details
    ISSN: 1550-7408
    Quelle: Blackwell Publishing Journal Backfiles 1879-2005
    Thema: Biologie
    Notizen: The taxonomy of the so-called Sporozoa is reviewed, and it is concluded that the group is polyphyletic and should be split into the following independent taxa: (1) The subphylum EUSPORA subph. nov., members of which have simple spores without polar filaments; this subphylum contains the classes TELOSPORASIDA Schaudinn, 1900 and HAPLO-SPORASIDA Caullery and Mesnil, 1899; (2) the subphylum CNIDOSPORA Doflein, 1901, members of which have spores containing 1 or more polar filaments; (3) the class PIRO PLASMASIDA Wenyon, 1926, members of which have no spores, are parasitic in vertebrate erythrocytes and are heter-oxenous; and (4) the class TOXOPLASMASIDA Biocca, 1957 emend., members of which have no spores, have cysts or pseudocysts, and are monoxenous parasites of vertebrates; the latter two groups are not assigned to subphyla but are considered appendages to the Protozoa. A classification to suborders is given of the Euspora.

    PHENOMENES ANORMAUX EN SISMIQUE REFLEXION (1961)
    Oxford, UK : Blackwell Publishing Ltd
    Geophysical prospecting 9 (1961), S. 0 
    Details
    ISSN: 1365-2478
    Quelle: Blackwell Publishing Journal Backfiles 1879-2005
    Thema: Geologie und Paläontologie , Physik
    Notizen: Abnormal phenomenons such as refractions and diffractions are more readily seen on cross-sections produced in magnetic processing offices than on single records. The result is that the understanding of these phenomenons intervenes more and more in the interpretation of the data.Our purpose is to proceed here to a restatement of the geometric properties related to these phenomenons and to make an attempt to distinguish between what is useful for the interpretation and what is not.To begin with we shall call our attention on diffractions and refractions over faults permitting to recognize the faults or to precise them, then on diffractions caused by irregularities of the surface forming the common boundary of heterogeneous media (more or less deep erosion surface, basement rock, …). The following phenomenons are classified as parasites:〈list xml:id="l1" style="custom"〉1) refractions following very shallow horizons, mostly related to topographic accidents,2) diffractions on the upward path caused by shallow faults,3) diffractions in the horizontal plane, found either in marine seismic or in case of heterogeneities “wrapt up” inside of an homogeneous overthrust.

    SELF-FEEDING OF SILAGE (1961)
    Oxford, UK : Blackwell Publishing Ltd
    Grass and forage science 16 (1961), S. 0

    Notizen: Self-feeding of silage has been successfully practised at Tillycorthie for 5 years. With unrestricted access to the feeding face, daily grazing times for 9-cwt. animals varied from 4 periods totalling 121 minutes in the case of stronger animals to 7 periods totalling 378 minutes.In feeding, chopped silage was more wasteful than long silage. The daily intake of 7-cwt. animals was 68 lb. of silage and 4 lb. of oat straw. The labour requirement for 70 animals was 6–6 hours per week.Food and labour costs on the system were 10s. 11d. per week. The estimated cost of the same items on. turnips and straw feeding is 16s. 4d. per week.The health of the cattle was good and growth excellent, and the animals went out to graze in a condition which allowed them to make maximum liveweight gain on grass.
