    Notes: The role of the State in promoting Indian economic development in the nineteenth century is one of several aspects of modern Indian economic history which have been ‘re-interpreted’ in recent years. The conventional wisdom once portrayed the policy of the British government in India as one essentially geared to serving British economic interests. By means of ‘discriminatory interventionism’ in economic affairs, it was argued, the Government encouraged the development of a primary commodity export economy, with all its attendant defects, in India. However, over the last two decades the reputation of the Government of India has undergone a rather noticeable transformation. Economic imperialists became, first, benevolent nightwatchmen, and then ‘development-orientated’ officials formulating an embryonic unbalanced growth model for Indian development. Parallel with this improvement in the Government of India's reputation has been a deterioration in the economic reputations of certain other governments in nineteenth-century developing economies, governments whose performances used to be favourably compared with that of the British in India. In the cases of Japan and Tsarist Russia, for instance, both the extent and effectiveness of State intervention in the economy has been questioned, and there has been an increasing recognition of the primacy of non-governmental factors in the economic growth of those countries. Given the ideological and organizational parameters limiting the range of possible activity by any nineteenth century government in its economy, the performance of governments in other developing countries of the period, and the political constraints imposed by being a subordinate section of a world-wide Empire, it is no longer possible regard the actions of British officials in India as wicked, and many would now regard them as almost respectable.

    Notes: Summary Disturbances in the functional properties of tumor mitochondria have been studied during the course of induction of haemorrhage brought about by endotoxin in the murine Crocker sarcoma (S 180). Extensive impairment of function was already present in mitochondria isolated from control tumors, as shown by low respiratory control ratios. The existing mitochondrial damage intensified promptly in response to injection of endotoxin long before the onset of haemorrhage at 4 h. The nature of the additional damage took two forms, depending on the duration of exposure to endotoxin; first, at 30 min, a true uncoupling of oxidative phosphorylation was seen, largely reversible in vitro by pre-treatment of the isolated organelles with bovine serum albumin (BSA). Second, at 1 h and later, oxygen utilisation in the presence of succinate, ADP and inorganic phosphate (P i) was depressed. The pre-addition of BSA consistently lowered respiration rates with succinate andP i in all preparations. The extent of endogenous inhibition of the adenine nucleotide translocase appeared unaltered by endotoxin in vivo.

    Notes: Summary Isolates ofTrichoderma spp. from pasture soils of Nova Scotia produce at least 7 toxic peptides, probably related to alamethicin, some of which inhibit the growth of cellulase producing rumen bacteria. One of the peptides has been obtained in crystalline form and crystal data on this material is reported.

    Notes: Abstract The strand relationships of adjacent pairs of chiasmata have been examined in differentially stained meiotic bivalents following in vivo BrdU substitution and FPG staining. A test for chromatid interference is described, based on comparisons of the observed numbers of various combinations of “hidden” and “visible” crossover exchanges with the numbers expected assuming no chromatid interference. A comparison based on 67 pairs of chiasmata from Locusta migratoria indicates no evidence for chromatid interference in this material.

    Notes: Abstract This paper presents a detailed examination of the sister chromatid exchanges (SCEs) observed in differentially stained meiotic chromosomes of Locusta migratoria following BrdU incorporation in vivo. The mean SCE frequencies of the different chromosome groups showed a clear positive relationship to chromosome length and the distribution of SCEs among M group bivalents and among X chromosomes fitted the Poisson distribution indicating a random, uncontrolled, distribution of meiotic SCEs among chromosomes, which contrasts sharply with the regular and highly controlled distribution of non-sister crossovers. Evidence was obtained that at least some SCEs are meiotic events, as opposed to spermatogonial relics. A limited comparison of SCE frequencies in meiotic and mitotic chromosomes of Locusta migratoria indicates that the special conditions obtaining in meiotic cells do not predispose them to increased levels of SCE.

    Notes: Summary Strains of Haplopappus gracilis (Nutt.) Gray cells resistant to 6-azauracil have been isolated from cultures of diploid cells. These strains are also resistant to 8-azaguanine, as is their parent. The variants are 100- to 125-fold more resistant to 6-azauracil than their parent, and they exhibit different spectra of cross resistance to other pyrimidine analogues. The phenotype of each variant is stable in the absence of selection. The majority of cells in cultures of the variants are diploid; all others examined were tetraploid. Initial rates of uptake of uracil are not reduced in the variants. Fluorouracil, to which two variants are resistant, is taken up by one of them as well as by the parent. Responses of the other two to fluorouracil are not correlated with decreased ability to accumulate this analogue.

    Notes: Abstract Charged-current neutrino and antineutrino interaction cross sections have been measured in the energy range 10 to 50 GeV using BEBC filled with a neon-hydrogen mixture. At these energies, σ/E was measured to be (0.73±0.08) 10−38 cm2/GeV per nucleon for neutrinos and (0.32±0.06) 10−38 cm2/GeV per nucleon for antineutrinos.

    Notes: Abstract The crystal and molecular structure of guanidinoacetic acid has been determined by single-crystal X-ray diffraction techniques. The crystals are monoclinic, space groupP21/c, witha = 4.942(3),b = 6.010(3),c = 21.911(14) Å, β = 128.60(4) °, andZ = 4. The structure was solved by direct methods, and refined by least-squares procedures toR = 0.070 for 552 observed diffraction maxima. The molecules are zwitterions linked by an infinite three-dimensional network of hydrogen bonds via the primary amine nitrogen and carboxylate oxygen atoms. The secondary amine nitrogen atom is not involved in hydrogen bonding.

    Notes: Abstract A criterion for susceptibility to hydrogen embrittlement based on the development of a critical hydrostatic stress has been proposed. The hydrostatic stress distribution ahead of plastically strained notches has been described analytically and correlated with measured susceptibility to hydrogen embrittlement. The predictions of the analysis are in good agreement with available experimental data and support the critical stress criterion for hydrogen embrittlement.
