    Notes: Using the experimental data on Fe–Mg exchange between orthopyroxene and biotite of Fonarev & Konilov (1986), an orthopyroxene–biotite geothermometer is developed. The thermometer is corrected for mixing of Ti and Al in octahedral sites in biotite and also for non-ideal mixing of Fe and Mg in orthopyroxene. The thermometer is applied to several amphibolite–granulite transition facies and granulite facies rocks and also to mantle xenoliths. It yields consistent results in rocks of widely varying bulk composition, and highly magnesian mantle xenoliths. This thermometer removes the difficulty of estimating temperature in garnet-free rocks in high-grade terrains and also provides independent estimates of temperature in garnet-bearing assemblages.

    Notes: There is some advantage in comparing price levels using consistent methods because this gives unique results. This paper examines some available methods of consistent comparison, pointing out difficulties associated with heterogeneous data, and suggesting adaptations yielding better comparisons. Next, the problem of non-availability of price and quantity decomposition is considered. Another problem relating to non-identical lists of commodities and quality differences is tackled by using linear programming instead of regression methodology, both methods using some transformed variables. The procedure suggested is likely eventually to be useful for comparison of dissimilar countries. Computations on some Indian population groups illustrate the findings.

    Notes: This paper has three parts. The first part attempts to analyse the prevailing situation in developing countries. The second part presents a feasible accounting system for such countries, by and large within the framework of the SNA. The third part goes beyond this and tries to obtain a more concise matrix (covering, in concept, those given in the accounting system) furnishing minimal sets of variables and classifications which one has, in any case, to play within the context of policy issues of developing countries. All three authors are jointly responsible for the first part. Uma Datta Roy Choudhury has drafted the second part. The third part has been drafted by the other two authors.

    Notes: The paper is concerned with non-monetized transactions which are dimensionally important in developing countries. The notion of degree of monetization attaches to all real flows. It is necessary to analyze non-monetized transactions in order to a have a better understanding of the producing and consuming activities of households which contribute a large part of national product in less developed countries. Among different non-monetized flows, particular attention is paid to the use of the output of own production for different purposes. A survey of Indian information on the degree of non-monetization shows that it is different for different flows: highest for consumption, intermediate for current inputs and lowest for investments. Cross section Indian data indicate that the degree of non-monetization is expected to fall with the improvement in the average household expenditure and urbanisation but it may rise if development occurs largely through agricultural improvement. Some of the Indian findings may apply to other developing countries as well. Normally, estimates of expenditure elasticities based on cross section data are obtained from consumption expenditure on a particular item (e) and the aggregate consumption expenditure (E) without going into the question of the degree of non-monetization of either element. Since traditional models of consumer behaviour apply only to the relation between money expenditure on a particular item (em) and the aggregate money expenditure (Em), it is suggested that the relation between e and E should be broken down into relations between (i) em and Em, (ii) ek and Ek where these are the corresponding kind elements and (iii)among E, Em and Ek. Some estimates of elasticity based on this scheme are presented indicating that the procedure is reasonable and suggesting that this type of analysis would probably furnish a suitable framework for answering relevant questions in the field.

    Notes: Glass ceramics containing micrometer-sized lead zirconate titanate have been synthesized and nanometer-sized lead sulphide (PbS) phase has been grown within these by treatment in hydrogen sulphide gas. The PbS particle sizes vary from 4.4 to 15.3 nm. Dielectric measurements on the nanocomposites have been carried out in the temperature range 120–300 K. The dielectric constant values for composites containing PbS exhibit drastic increase as compared to those of the glass ceramic samples. For specimens with PbS size varying from 4.4 to 15.3 nm the corresponding volume fraction of PbS being 0.07 and 0.14 the values range from 900 to 3500 at a frequency of 1 kHz. Bergman's [D. J. Bergman, Phys. Rev. C 43, 377 (1978)] analytical formulation with some density functions has been used to calculate the value of effective dielectric permittivity for the various nanocomposites. The theoretical values do not show any agreement with the experimentally observed data. However, more spectral weight functions need to be tried before any conclusion can be drawn regarding the mechanism responsible for the present experimental data. © 1998 American Institute of Physics.

    Notes: PbS particles of average diameters ranging from 9.9 to 18.0 nm have been synthesized within a polyacrylamide matrix. The percolative chains of these particles exhibit intrinsic semiconducting behavior at temperatures higher than 340 K. The estimated band gap for these particles are found to be much higher than that of bulk PbS being in the range 1.03 to 1.49 eV. The low-temperature conductivity of these composites appears to be controlled by an electron tunneling mechanism.

    Notes: Fractal growth of metallic silver within a polymer matrix has been induced by chemical reduction of a suitable sol. A fractal dimension of 1.73±0.01 over a length scale 100–10 000 nm has been estimated. The fractal structure consists of an aggregation of nanosized silver particles having diameters of the order of 15 nm. Electrical conductivity of these nanoparticles shows a lowering of the effective Debye temperature as the particle size is reduced.
