Electric Field Effects and Miscibility in Cybotactic Micellar Nematic and Ordinary Nematic Polyesters

1984

Abstract Miscibility behavior and electro-optical instabilities are reported for two main chain thermotropic nematic polyesters formed by regularly alternating a disubstituted azoxy-benzene mesogen with a flexible spacer containing either 7 or 10 methylene units (HEPTA-9 and DDA-9, respectively). Polymer HEPTA-9 displays an ordinary nematic organization and polymer DDA-9 forms a cybotactic nematic phase. Both are totally miscible with each other, and with PAA, in the nematic phase. Williams domains and dynamic scattering modes are observed in both cases.

Analysis of T-2 toxin by HPLC and GC in samples of corn and oats

1984

HPLC is the only physico-chemical method for the analysis of trichothecenes for which no derivatization is necessary. Hence a combination of different methods can be performed. For exclusion of any faulty interpretation of data and in order to decrease the detection limit HPLC should be followed by GC.

Im Vergleich dazu sind die wenigen Publikationen uber Experimente mit wissenschaftlicher schrittweiser Abklarung der Wirksamkeit, der vielfaltigen Reaktionsformen sowie deren Beeinflusbarkeit und Nebenreaktionen als Ausnahmen zu werten.

Self-Awareness and Coping Style: Differential Effects of Mild Physical Exercise

1984

Publisher Summary This chapter presents a study focusing on self-awareness and coping style. By using a multidimensional model of activation (arousal), the long-term effect of mild exercise (10 minute treadmill walk) was investigated in the chapter. Additionally, the habitual coping style and self-awareness of the subjects were assessed using a questionnaire technique. N = 40 male and female introductory psychology students served as subjects. The session for each subject lasted two hours with measures taken every 10 minutes on the self-report dimensions of the activation–deactivation adjective checklist and physiological indicators, such as heart rate, pulse volume amplitude, and skin cond…

Effcts of Dextran Sulphate (Dxs) on Lymphocyte Localization in Complement-Deficient Mice: Evidence that the Fifth Component of Complement is not Impl…

1984

AbstractThe effects of subcutaneously or intraperitoneally administered dextran sulphate (DXS) (5nmg/kg) on the subseguent 1 h localization of intravenously injected radiolabelled lymph node cells was investigated in complement deficient mice which lack C5.DXS proved to be equally as potent in depressing cell localizzation in deficient as compared to normal mice. These findings. indicate that the terminal complement components are not, essential for DXS activity.

The reference frequency distributions of daily relative sunshine from different locations

1984

Abstract In some applications the relative sunshine distribution curves are very usefull. The present work tends to provide the above frequency distributions for the Italian area, using the daily data of eleven stations. A preliminary compatibility test is applied in order to verify if a dependence on location exist and it is deduced that the area referring to the various locations is statistically compatible with a few exceptions. Therefore, it is possible to give generalized frequency distributions curves which can be considered reference curves for all Italian locations. The empirical distributions are also compared with the calculated ones by the method of Bendt et al. and a good agreem…

Chiva-Hoya de Buñol

1984

“Chiva-Hoya de Buñol” es una comarca de transición, entre l'Horta y Requena-Utiel. Cuajada de historia, pasó por épocas muy difíciles, como el despoblamiento sufrido en el siglo XVII, tras la expulsión de los moriscos por Felipe III, en 1609, reduciéndose su población en un 90%, el bandolerismo del XVII al XIX, o las guerras carlistas. Tras recuperar lentamente su demografía, se industrializó prematuramente, a través de las papeleras de Buñol —finales del XIX— origen de un movimiento obrero importante y pionero en el País Valenciano. Esta industrialización-; se consolidó con la instalación de las cementeras de Buñol, a partir de, 1917. Junto a una población industrial importante, tenemos qu…

Untersuchungen über das Benzothiiren

1984

Thermolyse und Photolyse von 1,2,3-Benzothiadiazol 10c, liefern die Produkte 11c – 15c. Mit Hilfe der 13C-Markierungstechnik wird gezeigt, das dabei kein intermediares Benzothiiren 1c gebildet wird. Isotopomere Reaktionsprodukte gehen auf H-Verschiebungen zuruck. Durch elektronenziehende Estergruppen in 6-Position wird der Ringschlus zu den substituierten Benzothiirenen 1d, e zwar nicht bei der Thermolyse, wohl aber bei der photochemischen Reaktionsfuhrung ermoglicht. Zum Nachweis dient eine eingehende Untersuchung der bei Thermolyse, Photolyse und auf einem unabhangigen Weg erhaltenen Disulfide 14d, e, bzw. 14d′, e′ und 14d˝, e˝. Die vorliegenden Ergebnisse basieren auf 13C- und 1H-NMR-Mes…

Surface Studies with Slow Positron Beaks

1984

Slow-positron physics is an exciting and rapidly advancing field. The continuing progress in the development of intense monochromatic beams of low-energy positrons has made it possible to perform a number of landmark experiments, where the interaction of the positron with solid surfaces plays a central role. These experiments either deal with fundamental atomic physics (positronium spectroscopy) or focus on the electronic and atomic properties of the surface region, using positrons as a probe. In the former category, the surface is involved just as an efficient source of positronium-like atoms. On the other hand, in the second category of experiments the surface i s the main object of study…

La compañía de libreros e impresores de Valencia: finanzas y cultura en el siglo XVIII

1984

La característica fundamental de la compañía que el 30 de noviembre de 1759 formaron en Valencia cinco mercaderes de libros y tres impresores, deriva del tipo de asociación que adoptaron, es decir, el constituir una sociedad por acciones. El desarrollo de este tipo de sociedades en la España del siglo XVIII resulta de enorme interés, puesto que contrasta con la forma más habitual con la que los comerciantes solían unir sus capitales y esfuerzo para la consecución de sus fines, utilizando un tipo de compañías que eran conocidas como generales o «colectivas», o, con menor frecuencia, las comanditarias.

Väinö Linnan Tuntematon sotilas konfliktiromaanina : normistojen taistelu

1984

Väinö Linna's novel "The Unknown Soldier" (1954) aroused more debate than any other work to date in Finland. A particular object of debate was his depiction of the Finnish soldier. Linna consciously set about destroying the myth of the idealistic Finnish soldier figure of J. L. Runeberg's 'Ensign Stool'. In thus doing, he assumed a position of conflict against the prevailing attitudes to the Finnish soldier. Väinö Linna's novel, however, also contains a powerful structural conflict. The progress of the plot relies integrally on the conflict inherent in it. His method in this regard is dialectical. A frame of reference for the conflict in the novel, as well as a code explaining it, is to be …

Die intravesikale Sonographie in der Stadieneinteilung des Harnblasenkarzinoms

1984

Bei der Therapieplanung und Prognose des Blasenkarzinoms spielt die Tiefe der Tumorinfiltration eine wichtige Rolle. Mit der Computertomographie ist eine Differenzierung des Tiefenwachstums von Blasentumoren in der Blasenwand selbst nicht moglich. Die Treffsicherheit der transabdominellen Sonographie bei der Stadieneinteilung des Blasenkarzinoms wird in der Literatur mit 85% angegeben [1]. Die intravesikale Sonographie ist der suprapubischen Ultraschalluntersuchung uberlegen: Schaller und Mitarbeiter [2] klassifizierten 26 von 28 Tumoren, also uber 90%, korrekt.

Biogenesis of the Yeast Cell Wall

1984

Yeast cells are covered by a rigid structure that protects the protoplast from osmotic changes and gives the characteristic shape to the cell. Studies on the composition of the wall of several species of yeast and other fungi have shown that they contain mainly polysaccharides with minor amounts of other materials. A completely rigid and continuous wall, nevertheless, would render growth impossible because cell extension would be restricted, so that an equilibrium must exist between softening (partial degradation) of wall and incorporation of new material into free ends of the polymers. From these considerations, it seems clear that the walls must be structurally and enzymatically a complex…
