    Notes:
    Individuals with selective absence of IgG1 and IgG2 were discovered by testing for allotypes and isotypes of the respective sub-classes. These individuals were homozygous for sub-class deleted Gm-Am haplotypes, as shown by allotype studies in two families (Gm-;…;g;A2ml/Gm-;n;b;A2ml and Gm-;n;b;A2ml/Gm-;…;b;A2ml) and by a population study of New Guineans (Gm fa;-;b;A2m2). The individuals with IgGl sub-class deficiency showed elevation of IgG2, IgG4 and in particular of IgG3.Gene deletion can result from unequal crossing over which renders a complementary chromosome with a duplication of a sub-class gene. In one family, duplication of γ3 genes was observed to have happened in one of a twin pair. Quantitation of sub-classes in families with γ1- and with γ3-duplicated haplotypes did not show increased levels of the gene involved.

    Notes:
    Summary A Samoyed-speaking group of fishers, hunters, and deer breeders numbering 1500 in total has been investigated. Seven territorial subgroups were examined with respect to 15 genetic systems. The presence of A2, cde, CwDe, Kpa, AK2, pc, Gmfb, and Gmfnb genes or haplotypes in low or moderate frequencies was observed. An unexpected finding was a deleted Gm(-;n;gb) phenotype in three siblings. Significant local genetic heterogeneity was observed with regard to AB0, Rh, Tf, PGM1, 6-PGD, and Gm systems. The summed genic heterogeneity was found to be highly significant (χ 132 2 =663.70, P〈 0.001). Mean Fst was equal to 0.0228, reflecting variation among subpopulations dispersed in the forest-tundra area and living under conditions of partial isolation.

    Notes:
    Conclusions Savinsk magnesite (lump and briquetted from the concentrate) can be thoroughly fired in rotary kilns of different sizes at a flame temperature of 1700–1750°C. The porosity of the powder is proportional to the size of the charge of raw material. During the firing of lump magnesite of all grades and briquette from ground concentrate it is possible to obtain powder with a porosity of 5–7%. When magnesite is being fired in a rotary kiln with a preparatory grid and when the raw materials charged amount to 1.5–2.0 times greater than when firing is done without the grid, a moderate-porosity powder is obtained. Thus, the fitting of a preparatory grid may increase the output of the furnace, and improve the quality of the product. During the firing of Savinsk lump and briquetted magnesite in rotary kilns in semiindustrial and industrial conditions, there is no bear formation, ringing, or crust formation on the lining of the furnace.

    Notes:
    Abstract We have used spectroscopic and magneto-optic methods to study the effect of defects on the transmission spectrum, thickness, refractive index, and period of the striated domain structure in thin iron garnet films exposed to fast neutron fluences of 4.5·1017 and 1019 cm−2. We observed both a decrease in transmission and a smearing of the interference maxima. The decrease in the quality of the interference fringes was observed in the visible spectrum for these samples. It was due to increased diffuse scattering of light by nonuniformities whose dimensions were comparable to the wavelength of the scattered light. It was determined that radiation defect clusters had no influence on the film thickness, but they did significantly alter the wavelength dependence of the refractive index and increased the period of domain structure striations.
