    Notes: Polygonized surface structure produced by furnace annealing GaAs wafers was studied by optical and scanning electron microscopy. The surface structure was revealed by chemically etching wafers which had been implanted with silicon and subjected to a furnace annealing cycle. Cathodoluminescence micrographs demonstrate an absence of impurity segregation to the polygon boundaries. No correlation was found between growth-induced dislocations and the polygonal networks. It is proposed that the surface structure results from a vacancy-condensation process. Related surface effects were observed for rapidly annealed wafers. A correlation between the furnace annealed and rapidly annealed GaAs is presented.

    Description / Table of Contents: Zusammenfassung Mikrokalorimetrische Experimente über oszillierende Wärmeerzeugung in stoffwechselndem zellfreiem Hefeextrakt werden beschrieben. Die Zuckersubstrate für die Glykolyse werden nach zwei verschiedenen Methoden zugeführt: (1) einmalige Addition von Trehalose, (b) Kontinuierliche Infusion von Glukose. Erstmalig wird die Kombination von Kalorimetrie und Substratinfusion bei oszillierenden biochemischen Reaktionen beschrieben.

    Notes: Abstract Microcalorimetric experiments on the periodic heat production in metabolizing cell free cytoplasmic extract from baker's yeast are described. The sugar substrates for glycolysis are supplied by two different techniques: (a) one-time addition of trehalose; (b) continuous infusion of glucose. For the first time the combination of calorimetry and substrate infusion technique is reported for oscillating biochemical reactions.

    Notes: We solve a nonlinear heat transfer problem using a general formalism based on the combination of the finite element and the optimal linearization methods. The results are compared with an ‘exact’ numerical iterative solution and the agreement is found to be good.
