    Notes: Objective To examine the relation between indices of maternal nutrition during pregnancy, including haemoglobin concentration, skinfold thickness and body weight, and the child's blood pressure at 10 to 12 years of age.Design Follow up study of children whose mothers had haemoglobin estimations, weights and skinfold thicknesses recorded during pregnancy.Setting Kingston, Jamaica.Subjects Seventy-seven children whose mothers took part in a prospective study of nutrition during pregnancy in relation to fetal growth.Main outcome measure Blood pressure at 10 to 12 years of age.Results The child's mean systolic pressure adjusted for current weight rose by 2.6 mmHg (95 % CI 0.5–4.6, P= 0.01) for each 1 g/dl fall in the mother's lowest haemoglobin during pregnancy. Mothers with a lower haemoglobin had thinner skinfold thicknesses, especially over the triceps (P= 0.005). In multiple regression analyses, taking account of the child's sex and current weight, there was a strong association between thin maternal triceps skinfold thickness at 15 weeks of gestation and raised blood pressure in the offspring. Taking account of the mother's triceps skinfold thickness abolished the relation between lower haemoglobin and raised blood pressure in the child. Lower weight gain between 15 and 35 weeks of gestation was independently associated with raised children's blood pressure. Systolic pressure rose by 10.7 mmHg (95 % CI 5.7 to 15.6, P= 0.0001) for each log mm decrease in the mother's triceps skinfold thickness, and by 0.6 mmHg (95% CI 0.1 to 1.0, P= 0.02) for each 1 kg decrease in the mother's weight gain during pregnancy.Conclusions These results parallel animal experiments suggesting that impaired maternal nutrition may underlie the programming of adult hypertension during fetal life.

    Notes: [Auszug] THE activity of skatole as a growth-promoting substance has been noted by Glover1. We have carried out experiments which show that skatole accelerates root formation in cuttings. Cuttings of Leptospermum sooparium and of Ficus repens were treated with an aqueous solution of ...

    APPROXIMATE RULES FOR THE COMPOSITION OF APPARENT RESISTIVITY SECTIONS (1974)
    Oxford, UK : Blackwell Publishing Ltd
    Geophysical prospecting 22 (1974), S. 0 
    Details
    ISSN: 1365-2478
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Geosciences , Physics
    Notes: Consideration is given to the form of apparent resistivity sections obtained by varying electrode array position and spacing over two dimensional features.Since basic solutions exist for horizontally layered media and for vertical or dipping single interfaces, simple rules are proposed whereby these solutions can be directly combined to give solutions for more complex sections. Substantial approximations may be involved as the rules do not fully allow for interactions between the constituents.The range of error incurred in application of the rules is explored, with particular reference to the square array system of resistivity measurement. The two extremes- of orientation of the square array with respect to the line of section are separately considered in this survey.Within appropriate limits, the rules appear extendable to a wide variety of simple structures for which rigorous solutions would be formidable. The rules are finally discussed in relation to practical applications.

    The excretion of 5-oxoproline in urine, as an index of glycine status, during normal pregnancy (1989)
    Oxford, UK : Blackwell Publishing Ltd
    BJOG 96 (1989), S. 0 
    Details
    ISSN: 1471-0528
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Medicine
    Notes: The urinary excretion of 5-oxoproline, which may be used as an index of glycine status, was investigated in 30 normal pregnant women during different stages of pregnancy and in 18 non-pregnant female volunteers. During an 18-h study there was little variation in the 5-oxoproline/creatinine index, and a single sample gave a representative value. The excretion of 5-oxoproline/creatinine (μmol/mmol) rose progressively as pregnancy advanced (non-pregnant mean 10, SD5, first trimester mean 46, SD 12, second trimester mean 150, SD 180, and third trimester mean 280, SD 320) and by the third trimester was over 20 times greater than in non-pregnant women. The data suggest that as pregnancy advances the endogenous production of glycine may be insufficient to satisfy the increasing demands.

    Notes: [Auszug] Three factors primarily motivated the present study. (1) The narrow bands observed along the ecliptic in the IRAS (Infrared Astronomical Satellite) data clearly seem to originate from dust particles in the main asteroid belt4'5; indeed, asteroid collisions may provide most of the dust grains that ...

    Notes: [Auszug] SIR,?In regards to an objection raised by Mr Eardley to the black hole ex planation of the Tungus event, I should point out that we do not make a claim for there being a flux of 1 per century over the Earth. In fact the only esti mate of substellar mass black hole mass density is that of Hawking ...

    Infrared brightness of a comet belt beyond Neptune (1988)

    Notes: Abstract We consider the infrared brightness of a flattened comet belt beyond the orbit of Neptune using a disk-like model with a power-law density distribution of comets. We compare this spectrum with the emission from a model zodiacal dust cloud in the ecliptic and with published IRAS data and present some consequences of dust in the comet belt.
