    Notes: The use of Very High Frequency measurements applied to the detection of the variation in dielectric constant as a precursor to earthquakes is examined. It is concluded that such a technique is feasible and that the installation of source and sensor in separate deep boreholes provides a suitable environment for this type of study. The boreholes could also be used for a considerable range of other types of instrumentation.

    Notes: Storage stability of quail eggs pickled in 50% vinegar solution and subsequently stored in glass jars with pickling solution or in flexible pouches without the solution at mean ambient (24°C, 58% RH) and refrigeration (5°C, 80% RH) temperatures was investigated. Pickle solution, egg white and yolk reached equilibrium pH (4.26–4.31) within 2 and 5 days of ambient and refrigeration storage, respectively. Eggs lost up to 12.2 and 8.8% of their weight within 48 h of ageing under ambient and refrigeration storage, respectively. Polypropylene (PP)-packed pickles suffered maximum weight loss followed by high-density polyethylene (HDPE)-packed eggs; losses were negligible in polyester/foil/polyethylene (PFP) laminate-packed samples. A decrease in phosphatidyl choline and phosphatidyl ethanolamine with simultaneous increase in lysophosphatidyl choline and lysophosphatidyl ethanolamine plus sphingomyelin occurred in pickled eggs during storage. Thiobarbituric acid (TBA) value increased and sensory quality declined with storage time. Aerobic plate counts remained fairly low throughout storage. HDPE (84 μm) was found to be an economic and efficient alternative packaging to glass jar for storage of pickled eggs without the pickle solution for up to 4 and 12 months of ambient and refrigerated storage, respectively.

    Notes: An important consideration in the investigation of liquid food quality degradation by oxidative reactions is the kinetics of oxygen uptake. The purpose of this research was to investigate oxygen uptake rates in a liquid food during storage. A commercially prepared infant formula was used as the model system. The influence of three variables (light intensity, storage temperature and initial concentration of dissolved oxygen) on the rate of oxygen uptake was determined. Results of the study indicated that the oxygen uptake in liquid foods follows fist order rate kinetics during the first 24 hr of storage. In the range of 0–4300 lux, it was found that the rate of oxygen uptake increases linearly with increasing light intensity. The rate of oxygen uptake at three different levels of initial dissolved oxygen from 1 mg/liter to nearly saturation showed that the rate of oxygen uptake increases linearly with increasing initial dissolved oxygen concentration. The influence of temperature on rate of oxygen uptake indicated that the Arrhenius equation could be used to describe the relationship.

    Notes: [Auszug] It is well known that the global thunderstrom activity is at a maximum at the temperate latitude and decreases with increasing latitudes7. The parameters or mechanisms controlling the guidance of thunderstorm-generated low-frequency waves are less effective at low latitude, however, which seems to ...

    Notes: The primary objective of this study was to determine the convective heat transfer coefficient which could be expected in a fluidized bed retort when the heating medium was air fluidized silica sand. An average heat transfer coefficient of approximately 329 W/(m2C) was experimentally determined. Curves for heating conduction and convection type foods in a fluidized bed and a rotary steam retort are compared.

    Notes: Abstract An analytical study is performed to examine the heat transfer characteristics on the flow of a viscous, incompressible rarefied gas in a parallel plate channel under the action of transverse magnetic field when (i) suction velocity normal to the plate is constant, (ii) the second plate oscillates in time about a constant non-zero mean, (iii) fluid is subjected to a constant heat source of absorption type. Apprximate solutions for velocity, temperature, phase, and amplitude of skin-friction and rate of heat transfer are evaluated. Mean temperature profiles, phase and amplitude of rate of heat transfer at both plates are discussed graphically followed by a quantitative discussion. Mean rate of heat transfer is tabulated in Table I.

    Description / Table of Contents: Zusammenfassung Eine spektrophotometrische Methode zur Bestimmung von Spuren Cyanid in wäßrigem Milieu mit Hilfe eines mit Hg(II) komplexierten heterocyklischen Azofarbstoffes wurde beschrieben. Hierbei verdrängt ein stärker komplexierendes Anion das Farbreagens aus dem Metallkomplex. Ammonium(2′-amino-3′-hydroxypyridyl-4′-azo)benzol-4-arsenat (AHP-4A) in komplexer Verbindung mit Hg(II) wurde für die genaue Bestimmung von 0,13–1,46μg CN−/ml verwendet. Das Anion wurde auch nach der Reaktion von Cyanid mit Hg(II)-(AHP-4A)-Komplex (wahrscheinlich zu einer Brückenverbindung) bestimmt. Der Anstieg der Extinktion ist der Cyanidkonzentration im Gebiet 0,04–0,37μg/ml proportional, aber dieses Verfahren ist nicht sehr genau. Der Einfluß von Fremdionen wurde untersucht. Die Empfindlichkeit anderer Hg(II)-Komplexe wurde zum Vergleich herangezogen.
    Notes: Summary A simple spectrophotometric method for the determination of trace amounts of cyanide ions in aqueous medium, using a heterocyclic azo dye complexed with mercury(II) for the first time, is described. The visual comparative method has been used in which a stronger complexing anion displaces a coloured reagent from the metal-ligand complex. Ammonium (2′-amino-3′-hydroxy-pyridyl-4′ azo)benzene-4-arsonate (AHP-4A) complexed with mercury(II) has been used for the determination of 0.13–1.46μg/ml of cyanide ions with fair accuracy. The anion has also been determined, when cyanide ion reacts with mercury(II)-(AHP-4A) complex, probably forming a bridged complex. The increase in absorbance is proportional to the cyanide ion concentration in the range of 0.04–0.37μg/ml, but this method is not very precise. The effect of foreign ions has also been studied. The sensitivities of other mercury(II) complexes in the determination of cyanide ions have been compared.
