    Notes: Summary In this paper we present some recent work on typhoon prediction with a high resolution global model. The emphasis of this paper is on typhoon recurvature. Here we include examples of successful typhoon recurvature track forecasts made from a very high resolution global spectral model. The main objective of this study however is to go beyond the forecasts, i.e. to interrogate the history tapes and to diagnose residue-free budgets of the divergence and vorticity. The premise of this paper is that the recurvature of the typhoons depends on both the usual advection of vorticity by the layer mean winds and the advection of divergence in the outflow layers of the storm. The region immediately outside the heavy rain area of the storm experiences large values of divergent outflows which contribute a significant advection of divergence. Through the Dine's compensation this region must, in consort, experience an enhancement of low level convergence and of deep convection, thus contributing to the storm motion. We distinguish two facets of storm motion and recurvature, one based on the conventional steering that invokes the advection of vorticity by a vertical integrated flow, the other is the generation mechanism proposed here. During recurvature the storm appears to move in a direction which is influenced by the rotational and the divergent flow dynamics. Increased vertical resolution in the outflow layer is shown to resolve stronger amplitudes in the outflow layer divergence and thus to contribute to improved forecasts of recurvature. A number of processes seem to simultaneously evolve, these include the strong advection of divergence part of the wind, enhancement of cumulus convection over this region, an enhancement of lower tropospheric convergence, generation of vorticity of the lower troposphere and the attendant recurvature.

    Notes: Abstract An investigation has been made of the formation of glyoxylic acid by the electrochemical reduction of oxalic acid/sulphuric acid aqueous solutions at various temperatures and cathode potentials using lead electrodes. It has been found that for a given quantity of electricity passed greater current efficiencies are obtained at higher electrode potentials and lower temperatures. The current efficiency decreased with increasing quantity of electricity passed. A simple analysis for the process has been made in which glyoxylic acid is assumed to be reduced to glycollic acid. By incorporation of a variable factorf, to take into account electrochemical parameters for the two reactions, satisfactory predictions of the current efficiency have been obtained. The electrokinetic interpretation of thef-factor is also briefly discussed.

    Notes: Poly(α-methyl styrene-co-acrylonitrile) was found to be miscible with poly(methyl methacrylate-co-ethyl methacrylate) and with poly(methyl methacrylate-co-n-butyl methacrylate). All these blends exhibited lower critical solution temperatures. Poly(styrene-co-acrylonitrile) was also found to be miscible with poly(methyl methacrylate-co-ethyl methacrylate) and with poly(methyl methacrylate-co-n-butyl methacrylate). However, phase separation of these blends could not be induced by heating up to 300°C.
