    Notes: The Mm. scaleni of 20 bovine cadavers were dissected and their attachments and nerve supply are described and illustrated. The literature is reviewed and the principles of subdividing the muscles are discussed. The emerging roots of the brachial plexus rather than the axillary vessels are taken as the dividing line between the middle and ventral scalene muscles. This principle can also be applied to the other domesticated species. Fascicles formerly described as M. iliocostalis cervicis are grouped with the M. scalenus medius as its Pars superficialis on the ground of their nerve supply. The scalene muscles are innervated by the ventral branches of spinal nerves C4—T2. The subdivisions and innervation in the ox are as follows: 1. M. scalenus dorsalis, C5—T2. 2. M. scalenus medius: Pars superficialis, C4—C8; Pars profunda, C8. 3. M. scalenus ventralis, C4—T2.

    Notes: Summary The survival curves obtained when cellular recovery follows various first radiation dose deliveriesDI seem, when semi-logarithmically plotted, to be translated from the part of the curve corresponding to an unfractionated irradiation beyond a doseDR. A possible assumption consistent with such experimental observations is proposed which allows the generalization of any survival modelS = f(D). The derived equationS = f(DR + D - DI)f(DI)/f(DR) is convenient for the whole family of experimental survival curves involving cellular damage repairs when the first radiation doses vary. All the parameters of the family equation can be simultaneously fitted so that their reliability is increased. The generalized equations are given for the four following models: two-hits targets, Chadwick and Leenhouts, Green and Burki, Wideröe. As an example, the Chadwick and Leenhouts generalized model parameters are fitted to a family of experimental survival curves concerningChlorella cells exposed to fractionated and continuous gamma irradiation. The fittings are presented with their confidence limits and are briefly discussed.

    Notes: Abstract Sub-potassic nephelines in the system NaAlSiO4(Ne)-KAlSiO4(Ks) were synthesized under a variety of conditions and studied at room temperature and up to 1000 °C using an X-ray powder diffractometer. At low temperatures they do not have the hexagonal structure determined by Hahn and Buerger (1955) for natural nepheline. Samples with ∼0.7 to 2.5 mole % Ks have an orthorhombic supercell with parameters equivalent to a, √3a, 3c where a and c are Hahn and Buerger structure cell parameters. Nephelines with 0 to ∼0.7% Ks consist of two phases with different c axes; one of these phases has the orthorhombic supercell. Pure-Na nephelines (NaAlSiO4) invert to a hexagonal phase with the Hahn and Buerger structure at 190 °±10 °C; this inversion temperature decreases with increasing Ks and a sample with 0.5% Ks inverts at 170 °±5 °C. The inversion is reversible and is displacive. Another reversible inversion begins at 875 °±10 °C in pure-Na nepheline; this inversion increases in temperature with increasing Ks and a sample with 1.8% Ks begins to invert at 960 °±10 °C. Superstructures with “anomalous” low-temperature cell parameters in sub-potassic nephelines are attributed to reversible collapse of the framework about the larger cation sites which must be occupied by small Na in subpotassic nephelines. Superstructures in natural nephelines are also related to framework collapse at a displacive inversion.
