    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.

    KINETICS OF OXYGEN UPTAKE IN LIQUID FOODS (1976)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of food science 41 (1976), S. 0 
    Details
    ISSN: 1750-3841

    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: Abstract Complex formation of indium(III) with three disubstituted pyridines, viz., 2,3-dihydroxypyridine, 2-amino-3-hydroxypyridine and 3-hydroxypyridine-2-thiol has been studied polarographically (μ=0.1; temp.=25±0.1°C). All the systems show reversible electrode behaviour.DeFord andHume method as modified byIrving has been applied for determining composition and stability constants. Distribution of different species as a function of ligand concentration has been calculated and shown graphically.

    Bond strengths and reproportionation constants of mixed ligand complexes of lanthanones (1978)

    Description / Table of Contents: Zusammenfassung Es wurden 1∶1∶1-Komplexe von Lanthaniden [Ln(III)] mit Nitrilotriessigsäure (NTA) und 2-Hydroxy-2,4,6-cycloheptatrien-1-on (Tropolon;TR) als gemischte Liganden potentiometrisch in 50% (v/v) wäßr. Dioxan bei μ≊0,1M-NaClO4 und 30±1°C untersucht. Die Komplexbildungskonstanten wurden mittels einer gewichteten Fehlerquadrat-Methode berechnet. Es zeigte sich, daßNTA undTR inkompatible Liganden gegenüberLn(III) sind und die gemischten Komplexe somit eine geringere Stabilität als die jeweiligen einfachen Komplexe haben.
    Notes: Abstract 1↮1↮1 mixed ligand complexes of lanthanones with nitrilotriacetic acid (NTA) and 2-hydroxy-2,4,6-cycloheptatrien-1-one (tropolone:TR) have been studied potentiometrically in 50% (v/v) aq. dioxane medium at μ≅0.1M-NaClO4 at 30±1°C. For these systems, complexation of primary ligand (NTA) with lanthanones is complete before complexation withTR takes place. The formation constants have been calculated by a weighted least squares method. The results show thatNTA andTR are incompatible ligands towards lanthanones and hence the mixed ligand complexes formed have lower stability than either of the parent complexes.

    Description / Table of Contents: Zusammenfassung Die Stabilitätskonstanten von Übergangsmetallchelaten von 1,3-disubstituierten 5-Hydroximino-hexahydropyrimidin-2,4,6-trionen [Diphenyl-violursäure (DPhVA) und Di-o-,m- undp-tolyl-violursäure (DiToVA)] wurden in 75% wäßr. Dioxan bei 30±1°C unter Konstanthaltung der Ionenstärke (0,1M-NaClO4) bestimmt. Folgende Reihung wurde gefunden: $$UO_2 〉 Cu 〉 Ni \geqslant Fe 〉 Co 〉 Pb 〉 Zn 〉 Cd 〉 Mn.$$ Der stabilitätsbeeinflussende Effekt von π-Donor-Bindungen (Metall—Ligand) wurde nachgewiesen. Effekte von elektrophilen und nucleophilen Zentren innerhalb der Liganden wurden mit Stabilitätskonstanten der Chelate und Dissoziationskonstanten der Säuren korreliert.
    Notes: Abstract Stability constants of transition-metal chelates of 1,3-disubstituted 5-hydroximino-hexahydropyrimidine-2,4,6-trione [diphenyl violuric acid (DPhVA) and di-o-,m-, andp-tolyl violuric acid (DiToVA)] have been determined in 75% dioxane (aqueous) at 30±1°C, in solutions containing an excess of the ligand at ionic strength 0.1M-NaClO4. The order of formation constants found is: $$UO_2 〉 Cu 〉 Ni \geqslant Fe 〉 Co 〉 Pb 〉 Zn 〉 Cd 〉 Mn.$$ The stability influencing effects of donor π-bond (metal to ligand) has been demonstrated. The effects of electrophilic and nucleophilic centres within the ligand have been correlated to stability constants and acid dissociation constants.

    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: Summary A thermodynamic study has been made of the ion exchange of Na- and Ca-illite with Al ions. From the exchange isotherms at 25 and 50°C the changes in free energy, enthalpy and entropy for the reactions were calculated. The isotherms, separation factors and free energy changes indicated a preference of Na and Ca ions by the illite.
