Measurement of body composition is increasingly important in research and clinical settings but is difficult in very young children. Bioelectrical impedance analysis (BIA) and air displacement plethysmography (ADP) are well-established but require specialist equipment so are not always feasible. Our aim was to determine if anthropometry and skinfold thickness measurements can be used as a substitute for BIA or ADP for assessing body composition in very young New Zealand children. We used three multi-ethnic cohorts: 217 children at a mean age of 24·2 months with skinfold and BIA measurements; seventy-nine infants at a mean age of 20·9 weeks and seventy-three infants at a mean age of 16·2 weeks, both with skinfold and ADP measurements. We used Bland–Altman plots to compare fat and fat-free mass calculated using all potentially relevant equations with measurements using BIA or ADP. We also calculated the proportion of children in the same tertile for measured fat or fat-free mass and tertiles (i) calculated using each equation, (ii) each absolute skinfold, and (iii) sum of skinfold thicknesses. We found that even for the best equation for each cohort, the 95 % limits of agreement with standard measures were wide (25–200 % of the mean) and the proportion of children whose standard measures fell in the same tertile as the skinfold estimates was ≤69 %. We conclude that none of the available published skinfold thickness equations provides good prediction of body composition in multi-ethnic cohorts of very young New Zealand children with different birth history and growth patterns.

Studies of the subsurface microbiology of the Äspö Hard Rock Laboratory, Sweden have revealed the presence of many different bacteria in the deep groundwaters which appear to maintain reducing conditions. Experiments were conducted to study the rock-water and microbial interactions. These used crushed Äspö diorite, Äspö groundwater and iron- and sulphate-reducing bacteria in flowing systems under anaerobic conditions. In column experiments, there was evidence of loss and mobilization of fine-grained crushed material (<5 μm) which had originally adhered to grain surfaces in the starting material. The mobilized fines were trapped between grains. The degree of mineralogical alteration was greater in the experiments when bacteria were present. In both column and continuously stirred reactor experiments, there is evidence for the formation of a secondary clay. These experiments have shown that microbial activity can influence rock-water interactions even in nutrient-poor conditions.

Conjugated polymers have been proposed as promising materials for scaffolds in tissue engineering applications. However, the restricted processability and biodegradability of conjugated polymers limit their use for biomedical applications. Here we synthesized a block-co-polymer of aniline tetramer and PCL (AT–PCL), and processed it into fibrous non-woven scaffolds by electrospinning. We showed that fibronectin (Fn) adhesion was dependent on the AT–PCL oxidative state, with a reduced Fn unfolding length on doped membranes. Furthermore, we demonstrated the cytocompatibility and potential of these membranes to support the growth and osteogenic differentiation of MC3T3-E1 cells over 21 days.

Since their introduction more than forty years ago, antenatal glucocorticoids have become a cornerstone in the management of preterm birth and have been responsible for substantial reductions in neonatal mortality and morbidity. Clinical trials conducted over the past decade have shown that these benefits may be increased further through administration of repeat doses of antenatal glucocorticoids in women at ongoing risk of preterm and in those undergoing elective cesarean at term. At the same time, a growing body of experimental animal evidence and observational data in humans has linked fetal overexposure to maternal glucocorticoids with increased risk of cardiovascular, metabolic and other disorders in later life. Despite these concerns, and somewhat surprisingly, there has been little evidence to date from randomized trials of longer-term harm from clinical doses of synthetic glucocorticoids. However, with wider clinical application of antenatal glucocorticoid therapy there has been greater need to consider the potential for later adverse effects. This paper reviews current evidence for the short- and long-term health effects of antenatal glucocorticoids and discusses the apparent discrepancy between data from randomized clinical trials and other studies.

Alcohol consumption during pregnancy remains common in many countries. Exposure to even low amounts of alcohol (i.e. ethanol) in pregnancy can lead to the heterogeneous fetal alcohol spectrum disorders (FASD), while heavy alcohol consumption can result in the fetal alcohol syndrome (FAS). FAS is characterized by cerebral dysfunction, growth restriction and craniofacial malformations. However, the effects of lower doses of alcohol during pregnancy, such as those that lead to FASD, are less well understood. In this article, we discuss the findings of recent studies performed in our laboratories on the effects of fetal alcohol exposure using sheep, in which we investigated the effects of late gestational alcohol exposure on the developing brain, arteries, kidneys, heart and lungs. Our studies indicate that alcohol exposure in late gestation can (1) affect cerebral white matter development and increase the risk of hemorrhage in the fetal brain, (2) cause left ventricular hypertrophy with evidence of altered cardiomyocyte maturation, (3) lead to a decrease in nephron number in the kidney, (4) cause altered arterial wall stiffness and endothelial and smooth muscle function and (5) result in altered surfactant protein mRNA expression, surfactant phospholipid composition and pro-inflammatory cytokine mRNA expression in the lung. These findings suggest that fetal alcohol exposure in late gestation can affect multiple organs, potentially increasing the risk of disease and organ dysfunction in later life.

A theoretical analysis of the effects of dual frequency ionosphere propagation correction on GNSS code tracking noise is presented. The effect on tracking noise of using different combinations of the proposed Galileo signals for ionosphere propagation correction is investigated. It is concluded that, for the open or commercial service user, the Galileo signals E2-L1-E1 near to and around GPS L1 should be used to apply ionosphere propagation corrections to the E5 signals. This produces a tracking noise standard deviation about three times larger than that on an E5 signal alone. An ionosphere correction-smoothing algorithm is presented that reduces the tracking noise on the corrected pseudo-range measurements.

Summary
Introduction
The physics, chemistry and biology of the sea surface are closely interrelated. Plankton in the water column produce an abundance of particulate and dissolved organic material, some of which is transported to the surface either passively by floatation or actively by bubble transport. Atmospheric deposition also enriches the sea surface with natural and anthropogenic compounds, which often accumulate there in relatively high concentrations compared with those in the water column. The abundance of organic matter at the sea surface provides a substrate for the growth of organisms that inhabit the sea surface microlayer: the neuston. Most studies suggest that the sea surface represents a highly productive, metabolically active interface. Organisms from most major divisions of the plant and animal kingdoms either live, reproduce or feed in the surface layers. Of particular interest are the microneuston, which may be involved in biogeochemical cycling, and neustonic eggs and larvae of commercially important fish and shellfish.
The quantities and types of anthropogenic chemicals entering the earth's atmosphere continue to grow. Many of these chemicals, some of which are highly toxic, are now globally distributed in the atmosphere and deposit to the sea surface even in remote areas. Due to stratospheric ozone depletion, ultraviolet-b (UV-B) radiation reaching the sea surface is increasing annually.

The methods for computer simulation of grain boundaries and hetero-interfaces in ceramics have long been available. We review developments in the field in two areas; the study of general grain boundaries and the simulation of hetero-interfaces. In both cases we discuss extrapolation from the symmetric case. We will also consider the validity of the continued use of classical potential models in an age of large-scale quantum calculations.

Retraction pockets of the pars tensa in children can result in erosion of the ossicles leading to hearing loss and eventually cholesteatoma formation. Several different types of treatment for the more severe grades of retraction pocket have been described. The aim of this pilot study was to assess the outcome following simple excision and ventiolation tube insertion of grade II, III and IV retraction pockets of the pars tensa. The eardrums were grades according to Sadé's classification (1979).
There were seven grade II and four garade III ratractions. Ten eardrums healed completely in a mean time of 3.6 months (mean follow-up 16 months) and there was one residual perforation. Two retractions recurred and both of these were only grade I. Clinically, an improvement in hearing was reported in seven children (eight ears) and the average air conduction threshold gain for these patients was 16 dB. A larger prospective study is currently underway.

The effect of long-term (10 weeks) treatment with growth hormone (GH) was investigated in twin lambs, one sibling being a control and the other treated with GH (0.1 mg/kg live weight per d). The lambs were fed on a concentrate-grass cube (9: 1 w/w) diet at a daily rate of 40 g fresh weightlkg Live weight. The average daily live-weight gain of the GH-treated lambs was 36% greater than that of the controls (307 v. 225 g/d, P < 0.01). The carcass composition of the GH-treated lambs changed: fat content was decreased (P < 001) and protein content was increased (P< 0.05) when expressed relative to carcass dry matter. The absolute weights and the weights when expressed relative to fleece-free empty body of some muscles were significantly increased in GH-treated lambs. The mean retention times of both particulate- and liquid-phase components of the digesta were unchanged by GH treatment, when calculated for the rumen or for the entire gastrointestinal tract. The feed conversion ratio was significantly greater (P < 0.01) in GH-treated lambs compared with controls. Nitrogen retained per g N intake was also significantly increased (P < 0.05) by GH treatment. Plasma urea concentrations were decreased (P < 005) and glucose concentrations were increased (P< 001) in GH-treated lambs, whereas non-esterified fatty acid concentrations were unchanged. Plasma insulin and total insulin-like growth factor-1 concentrations progressively increased in GH-treated lambs as treatment time continued. They were significantly correlated after week 4 of treatment. Two types of hepatic GH- binding site were detected, with high and low affinities for GH. The capacities of both binding sites were significantly increased (P < 0.05) in GH-treated lambs when expressed per unit microsomal protein but, when expressed per liver, only the capacity of the high-affinity site was increased.

The strong self-damped Lyman α absorption systems present in the spectra of high redshift QSOs represent a unique population of absorber which has recently been associated with the precursors of current disk galaxies. In a low resolution survey for what we have come to call “Lyman α disk systems” performed at Lick Observatory (Wolfe, et al. 1986, Ap. J. Suppl. 61, 249) approximately 18 systems with confirmed damped Lyman α profiles and rest frame equivalent widths greater than 5 Å were detected in a sample of 68 high redshift QSOs (Smith, Cohen and Bradley 1986, Ap. J. 310, 583). Subsequent higher resolution study has shown these systems to have the following properties (Turnshek, et al. 1988, Ap. J., in press):
1. Neutral hydrogen column densities, 2 × 1020 ≤ NHI ≤ 8 × 1021 cm−2.
2. Low-mixed ionization state. Typically the low ionization states dominate the high ionization states (e.g. CII ≫ CIV). Some enrichment has occurred, −2≲[X/H]⊙ ≲0.
3. Gas density, n ≲ 1 cm−3.
4. The gas shows two components, a quiescent (disk) component, σν ≲ 10 km s−1, and a turbulent (halo) component, σν ≲ 20 km s−1. Some systems show only the low velocity dispersion component.
5. At least one system intervening toward a radio QSO (Pks 0458-020) shows 21-cm absorption. The system shows multiple cloud structure with σν ≈ 6 km s−1, Ts ≈ 100 K, and structure extended over several kpc on the sky.
6. There is evidence that these systems may be self gravitating with scale height of the order of 300 pc.
7. These systems represent a unique population of absorber (distinct from the ‘Lyman a forest’ and heavy element systems) covering approximately 20% of the sky to z ≈ 3 and accounting for all of the baryonic matter at that redshift.

Hormone treatment for impotence and impotentia ejaculandi (delayed or absent ejaculation in the presence of normal erections and desire) (Johnson, 1965) is based on two assumptions: namely—that (1) potency in the male is androgen dependent and (2) impotency is due to relative androgen deficiency (Miller, 1968; Margolis et al., 1967; Sobotka, 1969). The synthetic preparations most frequently used are methyl testosterone, various esters, including the propionate, deconate, enanthate, etc. (Tuthill, 1955; Kupperman, 1967) and more recently a number of testosterone- ‘aphrodisiac’ combinations (Margolis et al., 1967; Cooper et al., 1971, etc.). Despite some claims of therapeutic success for the various regimes, the administration of exogenous hormones has several pharmacologic disadvantages. For instance methyl testosterone, which has to be taken sublingually or bucally, may be associated with severe toxic effects such as cholestatic jaundice, etc. (Goodman and Gilman, 1965). Parenterally administered testosterone esters, although less toxic and more certainly absorbed than methyl testosterone, have all the drawbacks of the intramuscular route; also their rate(s) of tissue release may not be optimal for metabolism. Additionally, all these synthetic compounds may inhibit endogenous testosterone formation and spermatogenesis by suppressing pituitary gonadotrophins. Long term administration may result in Leydig cell inactivity and even disuse atrophy. Recently Harkness et al. (1964, 1968) have observed that clomiphene (Fig. 1), a non-steroid triethylene derivative which in females stimulates the anovulatory ovary to secrete oestrogens (Bishop, 1970), significantly raised the levels of urinary steroid metabolites, including testosterone, in a proportion of ‘normal’ and corticosteroid deficient males. This unexpected testosterone elevating effect suggested its possible ‘experimental’ use as an alternative drug treatment in impotence. Accordingly a limited pilot study on five ‘primary’ (non-organic) impotent males was conducted: its main aims were (a) to assess the potential clinical utility of the drug and (b) to study its effects on the ‘pituitary-testes-axis' as reflected by plasma testosterone levels.

The Iron Age and Anglo-Saxon site at Upton near Northampton was excavated by Mr. Jackson on behalf of the Ministry of Public Building and Works, July—December 1965. In addition to Iron Age pits and ditches the principal discovery was that of a timber Saxon building which is remarkable for its combination of the structural features of a Grubenhaus with the dimensions and plan of a small timber hall. The building contained more than sixty loom-weights, and is interpreted as a weaving shed rather than a domestic occupation site. It was destroyed by fire, and charred timbers have revealed the position of internal fixed wooden furniture. From pottery and small finds it is suggested that the site was occupied in the late sixth to early seventh centuries A.D.

1. Three experiments using sixty individually fed, enzootic pneumonia-free Large White pigs on experiment from 9–11 weeks of age to 200 lb live weight are described.
2. Information was obtained on the effect of different dietary concentrations of aflatoxin B1 on the performance of the pigs, on various biochemical measurements and on the histology of the livers and kidneys.
3. Reduced growth rate and loss of appetite were the main adverse effects observed, their extent being positively related to the dietary level of aflatoxin B1. No marked clinical signs were seen, mortality was very low and there was little or no effect on the feed conversion efficiency of the animals.
4. No evidence for any adverse interaction between aflatoxin B1 and the presence in the diet of a supplement of copper sulphate providing 250 ppm Cu was apparent from either the performance, biochemical or histological results obtained. It was concluded that the few isolated reports of toxicity in growing pigs fed diets containing a supplement of 250 ppm Cu were unlikely to have been the result of the unsuspected presence of aflatoxin B1 in the feedingstuffs used in the diets.
5. Aflatoxin B1 tended to increase the serum alkaline phosphatase level, the concentration of Cu in the kidneys, and liver weight and to reduce the liver vitamin A concentration. No other consistent differences in the measurements made were observed.
6. The extent of the total pathological abnormality observed in the livers and kidneys was closely related to the level of aflatoxin B1 in the diet.
