    Notes: summary  The aim of this study was to compare the multidimensional properties among subtypes of painful temporomandibular disorders (TMD): myofascial pain (group I), disc displacement (group II), arthralgia (group IIIa) and osteoarthritis (group IIIb). A total of 511 patients answered a battery of questionnaires, which included questions relating to intensity and duration of pain, the Japanese version of the McGill Pain Questionnaire, limitation of daily functions, the Hospital Anxiety and Depression Scale, the Eysenck Personality Questionnaire short-form and 34 items of behavioural contributing factors. Group IIIb showed significantly the highest age in all subtypes. Those in group I had higher depression scores than those in group II (P=0·005). Group IIIa had a lower women's ratio than in group II (P=0·001) and the patients showed a shorter pain duration than those in groups I (P=0·000) and II (P=0·001). Group IIIa patients also showed lower visual analogue scale (VAS) ratings for pain descriptors ‘heavy’ (P=0·002) and ‘tiring’ (P=0·004) than those of group I, and ‘dull’ (P=0·005), ‘heavy’ (P=0·001) and ‘tiring’ (P=0·005) than those of group II. Group IIIa showed lower ratios of contributing factors of ‘an awareness of grinding/clenching during sleep’ (P=0·000) and ‘an awareness of clenching sensation when waking up at night’ (P=0·002) than those of group I, and also showed a higher ratio of ‘a liking for a hard food’ (P=0·000) and lower ratio of ‘talking for a long time on the telephone’ (P=0·001) than those of group II. In conclusion, although several properties were different between subtypes, the majority of them were similar in the four subtypes of TMD.

    Notes: Changes in crystal phase and electrical properties of oxides composed of Mn, Co, and Niwith the molar ratios of 5:2:1 and 3:3:1 were investigated. Starting oxides were fired from 250°C to800°C, then maintained at prescribed temperatures for 3 h in air. In the 5:2:1 specimen, a monophaseconsisting of a cubic spinel oxide that is important to electrical conductivity was obtained at firingtemperature of 800°C. In the 3:3:1 specimen, the monophase was obtained at temperatures rangingfrom 600°C to 800°C. Electrical resistance decreased exponentially with increasing temperature forall specimens fired at temperatures ranging from 250°C to 800°C, indicating that the oxides haveintrinsic thermistor characteristics with negative temperature coefficient (NTC). The temperaturedependence of the thermistor constant (B value) necessary for practical application was considered tobe related to the existence ratio of cubic spinel-type and ilmenite-type structures and the latticeconstant of the cubic spinel-type structure. The electrical conduction was stabilized by annealing atprescribed temperatures for more than 720 minutes

    Notes: Formability of tube in elevated temperature is essential data to design the warmhydroforming process parameters, such as tube diameter, forming temperature and die geometries.Since the quantitative data of forming limit can be used to predict the failure on forming process,formability data available on the FE analysis is one of the very important information for the optimumdesign. In this study, the effect of heat treatment conditions and deformation temperature on theformability was investigated for the warm hydroforming of Al6061 tube. Full annealing andT6-treatment are applied for the heat treatment of Al6061 tubes. To evaluate the hydroformability,uni-axial tensile test and bulge test were performed at temperature ranges between room temperatureand 300oC. The measured flow stresses were used as input parameters for the simulation of warmhydroforming process. The damage value and strain variation during hydroforming are analysed byFEM. A forming limit based on the ductile fracture criteria has been proposed by combining theresults of experimental and FE analysis for the estimation of formability and optimization of warmhydroforming process

    Notes: Summary Studies involving intracellular recording during extracellular drug administration have revealed that both glycine and GABA hyperpolarize and increase the membrane conductance of reticulospinal neurones, glycine usually being more effective than GABA. The inhibition of firing of some medullary reticular neurones produced by stimulating the ventrolateral area of the spinal cord (where reticulospinal axons lie) is blocked by strychnine, which blocks the depression by glycine without affecting that by GABA. Such inhibition is not reduced by bicuculline or picrotoxin in concentrations which block the action of GABA, but do not affect that of glycine. The synaptic inhibition of other reticular neurones is blocked by bicuculline or picrotoxin, but not by strychnine. Thus, both glycine and GABA are likely to be inhibitory transmitters in the medullary reticular formation, possibly released from axon collaterals of two different populations of inhibitory reticulospinal neurones.

    Description / Table of Contents: Der Einfluß von Kupfer(II) auf die Kristallisation von α-FeOOHα-FeOOH wurde in mehreren Proben ohne und mit Zusatz von Cu(II)-Ionen (bis zu 5 Atom-%) unter bestimmten Bedingungen dargestellt und röntgeno-graphisch, durch BET, DTA und elektronenmikroskopisch untersucht. Durch Zusatz von 2,5 Atom-% wird die Kristallisation des α-FeOOH vollständig verhindert. Geringe Cu-Zusätze verzögern die Kristallisation. Das Wachsen der Partikel- und Kristallitgrößen von reinem und Cu-dotiertem α-FeOOH unterscheidet sich. Nach der Theorie des Autors wird der Einfluß der Cu2+-Ionen auf die Verzerrung des Koordinationsgitters diskutiert. Es besteht vermutlich ein Zusammenhang zür korrosionshemmenden Wirkung von Kupferzusätzen im Stahl.
    Notes: Various α-FeOOH samples have been prepared with or without addition of Cu(II) (0-5% Cu/Fe) and examined by X-ray diffraction, BET surface area determination, electron-microscopical observation and DTA. Doping with Cu in suitable amounts impedes completely the formation of α-FeOOH. The mechanism of growth, based on the changes of particle size and crystallite dimension, appears to be different between pure and Cu-doped α-FeOOH. The reason of the remarkable effect of Cu on the crystallization process of α-FeOOH is discussed. The effect of Cu is likely relevant to the role of Cu added to anticorrosive steel used in atmospheric environment.

    Description / Table of Contents: Die Geschwindigkeit der Selbstzersetzung von Fe(OH)2 unter Luftausschluß wurde unter Zusatz von Cu(II) (0-6 Atom-%) bei 30 bis 50°C bestimmt. Das Maximum der Geschwindigkeit und ein Minimum der Aktivierungsenergie tritt bei 1% Cu/Fe auf. Dies wird zwei gleichzeitig wirksamen Einflüssen des Cu zugeschrieben: Erstens der Verzerrung des Koordinationskomplexes durch Cu2+, die die Strukturumwandlung in Magnetit erleichtert, dagegen wirkt negativ der Einfluß des Cu, der zur Vergrößerung der Fe(OH)2-Kristalle führt. Röntgenaufnahmen und elektronenmikroskopische Beobachtungen bestätigen die Annahme.
    Notes: The rate of self-decomposition of iron(II) hydroxide doped with various amounts (0-6 atomic%) of Cu(II) was determined in the absence of oxygen at the temperature range of 30 to 50°C. The maximum rate and the minimum activation energy were observed at 1% Cu/Fe. The result was attributed to the two simultaneous actions of Cu2+, i.e., the distortion effect on coordination complex of Fe2+ by Cu2+ to ease the structural transformation to magnetite and the hindering effect on magnetite formation revealed consequently in the growth of Fe(OH)2 crystals. Both effects were proved by X-ray diffraction and election-microscopic observations.
