    Notes: Hypophysectomized (Hypo-X) rats do not develop contact sensitivity to dinitrochlorobenzene (DNCB). Daily treatment with prolactin or growth hormone completely restores the DNCB-reactivity of Hypo-X animals. Treatment of such animals with ACTH, FSH, LH, TSH or HCG has no restoring potential. Treatment with ACTH in addition to prolactin or growth hormone antagonizes restoration of Hypo-X rats. These experiments indicate that the pituitary gland has the potential of regulating contact sensitivity.

    Notes: Hypophysectomized (Hypo-X) rats did not develop contact dermatitis in response to dinitrochlorobenzene (DNCB). Syngeneic pituitary grafts placed under the kidney capsule or daily treatment with prolactin restored the DNCB-reactivity of Hypo-X animals. Combined treatment with other pituitary hormones was ineffective. Treatment of normal rats with a potent prolactin antagonist drug, bromocriptine, was as effective in inhibiting contact sensitivity as was hypophysectomy. These results indicate that contact sensitivity is a prolactin dependent reaction.

    Notes: Recently one of the most significant research-field in the development of amorphousalloys is the research of the Cu-based amorphous alloys. The Zr-based alloys developed earlier canbe replaced by the newly developed Cu-based alloys as the high price of the Zr-based alloys limitstheir utilization in spite of their favourable properties. Production of Cu-based alloys having thesame or more favourite properties than Zr-based alloys is cheaper and this fact can promote theirincreasing utilization. Cu-Zr-Ti and Cu-Hf-Ti alloy systems – they are Cu-based alloys – haveexcellent mechanical properties. In this paper investigations of crystallization of amorphousCu44,25Zr36Ag14,75Ti5 powder produced by ball milling (these processes have not been investigatedyet according to the reference data) are described. In the course of investigation of thecrystallization process, samples were heated to a temperature of investigation by means of a DSCequipment and the developed state was frozen by chilling. The investigation of the developedstructure and to identify the phases formed during heat treatment, X-ray diffraction method wasused

    Notes: During thermomechanical treatment of austenitic stainless steel a’ martensite and emartensite form in the austenite matrix. The martensitic transformation and deforming existing together result a high elongation at the investigated steel belonging to the TRIP grades. The amount of a’and e martensite depends on the strain level as well as on the deforming temperature in this steel. In the course of thermomechanical treatments we measured the amount and texture of the existing phases at different temperature and strain. It has been stated that the martensites are dominant in low temperature range, they have a considerable amount, and the transformation from emartensite to a’ martensite also takes place. The amount of a’ martensite increases by increasing the strain while the amount of e martensite shows a maximum. By investigating the relationship between the quantity of existing phases and the effect of texture, it has been stated that the transformation takes place in certain given plates in the textured matrix

    Notes: The ageing phenomena and its effect on the thermoelastic martensitictransformation was investigated in three Cu-base SMAs. The transformation temperaturesshifted to higher temperatures due to aging in the beta-phase.To increase the alloy’s ductility, a definite amount of Mn (4 wt%) and Fe (2 wt%) were addedto the ternary alloy. The thermoelastic martensitic transformation was found in the not-agedsamples of the CuAlNiMn and CuAlNiMnFe alloys. This transformation was destroyed dueto ageing heat treatments by a fairly unknown exothermic process. The thermoelasticmartensitic transformation appeared again in the aged CuAlNiMn and CuAlNiMnFe samplesafter keeping them on room temperature for a few months.This phenomena was investigated by DSC, SEM, TEM, and XRD

    Notes: Copper alloys have many properties, which make them suitable in wide-rangingapplications in all the engineering industries. For the investigated alloys the most importantproperties are hardness, strength and electrical conductivity. Precipitation hardenable alloys werestudied by Jominy end-quench test, in order to examine the change of hardness, electricalconductivity and microstructure as a length of the test bar (i.e. cooling rate). In the first step sampleswere solution treated at different temperatures, then water quenched followed by aging. Cold-workafter quench was applied in some alloys and improve in the properties was clearly seen. Thefollowing Cu-alloys were investigated: Cu-Co-Ni-Be, Cu-2Be-Ni and Cu-2Ni-Be

    Notes: Summary The authors have applied intraosseous phlebography 38 times in 33 children, in order to assess the extent of damage to the femoral head circulation in fractures of the femoral neck and other disorders. Contrast medium was injected mostly into the epiphysis, but eventually into the metaphysis too. Results of these examinations have been important guidelines in the management of the disease, i.e. if the venous drainage of the contrast medium was delayed or absent, or if the contrast medium was congested in the head, the weightbearing had to be releaved until regenerative signs of the femoral head were seen.

    Description / Table of Contents: Summary The authors examined the growth of the body size of pheasant, partridge and mallard, the O2-consumption, the CO2-output and the energy production up to the end of the juvenile phase. In the case of the pheasant, the values of the base requirement, the maintenance requirement and the energyproduction consumption were determined. The rearing of the animals and the determination of the above parameters in the three game birds took place in each case under air temperatures set by the maintenance technology and with appropriate feeding. In order to establish the energy consumption (O2-consumption, CO2-output), indirect calometric methods were used in theVötsch controlled environment chamber with theNoyons diaphorometer. Average values were developed from the individual oberservations and presented graphically after logarithmic transformation. The graphs allowed conclusions on the biological phases present and the critical change of phases. According to the parameters measured, moulting plays an important role in the phase changes and in the accompanying changes in the temperature regulation. The authors point out that recognition of the critical biological development phases is now essential for the rational feeding of the birds and for their maintenance. The heat production determined indirectly by calorimeter allows the calculation of the ME-content of the dispensed food necessary for the age and the biological development phase and of the birds' growth and production-energy demand. The examination data can also be further used as a basis for the planning and building of breeding systems and equipment.
    Abstract: Résumé Les auteurs ont étudié la croissance corporelle du Faisan, de la Perdrix grise et du Canard colvert, leur consommation d'O2 et leur producton de CO2 ainsi que la production énergétique jusqu'à la fin de la période de croissance juvénile. Dans le cas du Faisan, les valeurs du métabolisme basal, du métabolisme d'entretien et du métabolisme de production ont été définies. L'élevage des animaux et la détermination des paramètres mentionnés ci-dessus furent établis, pour chacune des espèces d'oiseaux, en respectant les normes zootechniques de température de l'air et d'alimentation. Pour le calcul de la consommation d'énergie (consommation d'O2 et production de CO2), on applique des méthodes- des calorimétriques indirectes en chambre climatisée deVötsch avec le diaféromètre deNoyon. Des moyennes ont été calculées à partir des données individuelles et reportées sur graphique après transformation logarithmique. Les représentations graphiques firent apparaître les différentes étapes biologiques et la phase transitoire critique qui les accompagne. D'après les paramètres mesurés, la mue joue un rôle significatif sur les variations périodiques ainsi que sur les modifications qui interviennent au niveau de la thermorégulation. Les auteurs soulignent que le repérage des périodes biologiquement critiques est indispensable en vue de procéder à un nourrissage rationnel des animaux. Le relevé de la production de chaleur par la méthode indirecte de calorimétrie permet de calculer, en fonction de l'âge et des phases biologiquement vitales, la teneur nécessaire en protéines dans la nourriture dispensée ainsi que les besoins énergétiques propres à la production. Les données fournies par cette recherche pourront, en outre, servir de base à l'élaboration de dispositifs et de matériel destinés à l'élevage.
    Notes: Zusammenfassung Die Autoren untersuchten das Wachstum der Körpermasse bei Fasanen, Rebhuhn und Stockente, den O2-Verbrauch, die CO2-Abgabe und die Energieproduktion bis zum Ende des Jugendwachstums. Im Falle des Fasans wurden die Werte für den Grundbedarf, den Erhaltungsbedarf und den Produktions-Energieverbrauch bestimmt. Die Aufzucht der Tiere und die Ermittlung der oben genannten Parameter erfolgte bei den drei Flugwildarten jeweils unter von der Haltungstechnologie bestimmten Lufttemperaturen und entsprechender Fütterung. Zur Bestimmung des Energieverbrauchs (O2-Verbrauch, CO2-Abgabe) wurden indirekte kalorimetrische Methoden in der Klimakammer vonVötsch mit dem NOYONS-Diaferometer angewandt. Aus den einzelnen Untersuchungsdaten wurden Durchschnittswerte gebildet und nach logarithmischer Transformation graphisch dargestellt. Die diesbezüglichen graphischen Darstellungen erlaubten Aussagen zu den biologisch vorhandenen Etappen und dem kritischen Periodenwechsel. Nach den gemessenen Parametern hat die Mauser eine bedeutende Rolle für die zeitweisen Veränderungen sowie für die sie begleitenden Veränderungen der Temperaturregulierung. Die Autoren weisen darauf hin, daß das Erkennen der kritischen und lebensbiologisch vorhandenen Perioden für eine rationelle Fütterung der Tiere und ihre Haltung heute schon unentbehrlich ist. Die indirekt kalorimetrisch bestimmte Wärmeproduktion erlaubt es, den für das Lebensalter und die lebensbiologischen Eigenschaften erforderlichen ME-Gehalt im verabreichten Futter und den Wachstums- und Produktionsenergieanspruch zu errechnen. Die Untersuchungsdaten können weiterhin auch für die Planung und den Bau von Aufzuchtanlagen und -geräten als Grundlage dienen.

    Description / Table of Contents: Zusammenfassung Radiale Dichtedifferenzfunktionen für PC anda-PS werden im Temperaturbereich zwischen 393 K und 563 K aus Röntgenweitwinkel-Messungen berechnet. Die erforderlichen Korrekturen der experimentellen Intensitätsverteilung werden sorgfältig überprüft. Für einige Abstände kann eine erste Zuordnung ihres inter- und intramolekularen Ursprungs gegeben werden. Die Abstandswerte für die nächsten Nachbarn aus der RDDF stimmen mit den theoretisch berechneten Werten sehr gut überein.
    Notes: Summary Radial difference distribution functions were calculated for PC anda-PS in a temperature range from 293 K to 455 K using wide angle X-ray scattering. Corrections of experimental scattering curves were examined. An assignment for some distances to intra- and intermolecular correlations was made. Next neighbour distances obtained from RDDFs are in good agreement with theoretically computed distances.
