    Phenotypic plasticity in numbers of antennal chemoreceptors in a grasshopper: effects of food (1998)

    Notes: Abstract Grasshoppers, Schistocerca americana, reared from hatching on artificial diet had fewer sensilla on the antennae in the final larval stage than insects reared on lettuce. This was true of basiconic and coeloconic sensilla (presumed olfactory) and trichoid sensilla (presumed gustatory). The degree of difference varied along the antenna and with sensillum type. Adding salicin to the diet restored the numbers of all types of sensillum to levels equal to, or approaching, those in lettuce-fed insects. The addition of some volatile compounds – carvone (monoterpene), chalcone (flavonoid), citral (monoterpene) and guaiacol (phenolic) – resulted in slight increases in number, but coumarin (phenylpropanoid) had no effect. None of the compounds, either singly or in combination, produced more sensilla than were present in plant-fed insects.

    Notes: [Auszug] FOR the past four years a very simple form of tide-predicting machine, the invention of Captain A. Inglis, the harbour-master, has been in use at Port Adelaide for the construction of the yearly published tide tables. The tides at Port Adelaide are rather peculiar in their behaviour, this being ...

    Notes: [Auszug] ALONG the north-west coast of Australia the tidal wave, flowing in from the Indian Ocean, produces at most places a large rise and fall. At Port Darwin the mean spring range is about 24 feet, but the range is sometimes as much as 30 feet. A tide gauge of Lord Kelvin's pattern was set up here by ...

    Notes: Abstract. The neutron deficient 199At nucleus has been studied in the 175Lu+28Si reaction at Eb= 141 MeV. In order to select events of interest in the presence of the very strong background caused by fission, γ-rays have been detected in coincidence with recoiling evaporation residues. The excited states of 199At observed for the first time may indicate that this nucleus is deformed.

    Notes: Abstract: A series of new strongly coupled high-K, multi-quasiparticle structures have been observed in the light erbium transitional nuclei, 159Er and 160Er. The interpretation of these bands is discussed within the framework of the cranked shell model. These sequences, when taken together with the existing quasiparticle excitations, form a near complete set of low-lying, multi-quasiparticle structures on which a coherent series of aligned angular momentum, band crossing and blocking arguments can be based. The measured B(M1)/B(E2) ratios are compared with geometrical calculations to test the proposed configuration assignments.

    Evaluation of some statistical methods of interpreting multi-element geochemical drainage data from New Brunswick (1978)

    Notes: Abstract Univariate and multivariate statistical methods were evaluated using published multi-element stream sediment data from southwestern and northern New Brunswick. The statistical distributions of elements do not obey Ahrens' “law of lognormality”; eleven of thirteen elements investigated for the Bathurst-Jacquet River area are not lognormally distributed at the 0.05 level of significance. The distributions are positively skewed and leptokurtic and consist of aggregate populations which represent mineral deposits, bedrock, and many other physiographic factors; some of these populations are normally distributed. The efficiency of the Pearson correlation coefficient varied and was compared to nonparametric correlation. Various methods of factor analysis were evaluated and the structure of the factors was similar to the subjective groupings derived from the correlation matrices. Comparison of correlation coefficients and factor models derived from the log-transformed and untransformed Bathurst-Jacquet River data showed that background associations were enhanced by the log transformation at the expense of associations representing mineralization. Q-mode factor matrices could not be satisfactorily interpreted without recourse to the mapping of the factor loadings. The maps produced were inferior to simple concentration maps. An iterative technique was developed for discriminant analysis to refine the sample training groups representing mineralized and background terrain; repeated discriminant analysis after misclassified samples were eliminated altered the inherent character of the training groups. Trend surface analysis was found to give goodness of fits of the trend equations comparable to the fits expected from random numbers. The method was mathematically inappropriate for the type of data used. The goal of exploration geochemical statistical analysis should be to discriminate and sort populations representing mineralized and background populations by classification or filtering techniques.
