    Effects of Harvesting, Transportation, and Cryogenic Processing on the Microflora of Southern Peas (1984)

    Notes: Samples of southern peas [Vigna unguiculata (L.) Walp., cv. Purple Hull Pinkeye] were obtained at critical stages in a normal harvesting, transportation, and cryogenic processing operation and microbiologically analyzed for total plate count (TPC), Enterobacteriaceae count (ENT), and yeast and mold counts. Molds were identified to genera while ENT were identified to species. Operations involving extended holding times tended to increase all counts significantly, although subsequent processing reduced these counts to an acceptable level. Predominant genera of ENT and molds appeared to be soil borne organisms such as Enterobacter agglomerans, Enterobacter cloacae, Klebsella pneumoniae, and Serratia liquefaciens, and Fusarium, Cladisporium, Alternaria, Phoma, and Aspergillus, respectively.

    Diffusion Properties of Salt and Acetic Acid into Herring and Their Subsequent Effect on the Muscle Tissue (1984)
    Oxford, UK : Blackwell Publishing Ltd

    Notes: The diffusion of sodium chloride and acetic acid into herring muscle and their subsequent effects on the myotibrillar proteins were studied at different temperatures and fish:cure ratios. Acid was found to penetrate tissue more quickly than salt. The acid and salt cause an initial “hardening” of the tissue, the extent of which is proportional to the concentration of each, but it is considered that the resultant fall in pH activates muscle cathepsins. SDS PAGE indicated that proteolysis of the myosin heavy chains was concomitant with subsequent tissue softening. Electron microscopy detected little disintegration of myofilaments, but extensive break-up of Z-lines.

    The effect of bite force on the duration and latency of the menton tap silent period (1981)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of oral rehabilitation 8 (1981), S. 0 
    Details
    ISSN: 1365-2842
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Medicine
    Notes: The purpose of this research was to investigate the effect of bite force changes on the duration and latency of the menton tap silent period and particularly whether a decrease in bite force can increase the duration of the silent period to the extent which may be found in dysfunctional patients. The menton tap silent period was recorded from both anterior temporal and masseter muscles while the subject was clenching at different force levels. A bilaterally stable force transducer was used to monitor the clenching force. The results indicated no statistically significant differences in the mean durations and latencies of silent periods at different clenching forces. They suggest that duration and latency are not related to the degree of clenching force.

    A clinical and pharmacodynamic evaluation of sulpiride (1981)

    Notes: Abstract In a double-blind study the therapeutic efficacy of sulpiride was compared to that of haloperidol — an established neuroleptic agent. A total of 30 female patients with a diagnosis of chronic schizophrenia were initially stabilised on the dosage of haloperidol which produced optimum therapeutic response when given once or twice daily. The patients were then randomly allocated to receive either sulpiride or haloperidol over a period of 12 weeks. Plasma drug concentrations and prolactin levels were determined. Clinical effects were evaluated by Brief Psychiatric Rating Scale (BPRS), Wing Rating Scale, and Extrapyramidal Symptoms Rating Scale (EPS). A standardised side-effects checklist was used. Treatment with sulpiride was associated with a significant rise in plasma prolactin level, but paradoxically these patients had significantly reduced extrapyramidal symptoms. No significant correlation was found between plasma sulpiride concentration and prolactin level or any of the clinical variables. The study confirms the antipsychotic activity of sulpiride.

    On the factors affecting strength of portland cement (1984)
    Springer
    Journal of materials science 19 (1984), S. 150-158

    ISSN: 1573-4803

    Notes: Abstract This paper reports mechanical property measurements for Portland Cement paste free from fabrication artifacts (e.g. bubble-type voids), and compares them to published results both for normal and new high strength cement. Removal of large voids (above 100μm) by vacuum de-airing leads to an increase of ∼ 15% in mean flexural strength and a small decrease in fracture toughness. This increase in flexural strength is predictable from the tied-crack model previously proposed to explain the notch-sensitivity behaviour of hardened cement paste, and for which direct experimental evidence was obtained. It is suggested that factors such as moisture content are at least as important as large voids in controlling mechanical properties. It is concluded that the much increased strength of the new polymer-containing cements must result from improvements to the microstructure other than the simple elimination of voids.
