Analysis of pteridines in Pyrrhocoris apterus (L.) (Heteroptera, Pyrrhocoridae) during development and in body-color mutants
1997
By using thin-layer chromatography (TLC) and high-performance liquid chromatography (HPLC), five different pteridines have been quantified in extracts from Pyrrhocoris apterus: neopterin, isoxanthopterin, isoxantholumazine (violapterin), 7-methylxanthopterin, and erythropterin. Biopterin was also detected using HPLC. Pteridines have been analyzed separately in bodies and eyes of the wild type regarding developmental stage and sex. The pteridine content in both bodies and eyes increased from nymphs to 2-day-old adults. After this period, the concentration of pteridines in the eyes of adults remained approximately constant, while in the bodies isoxantholumazine, 7-methylxanthopterin, and isox…
Linkages between causal ascriptions, emotion, and behavior
1997
Italian schoolboys between the ages of 9 and 10 participated in three experiments guided by attribution theory as conceptualised by Weiner (1985, 1986). In Experiment 1, following teacher-emotional feedback of anger or sympathy for failure, attributional inferences regarding low ability or lack of effort as the cause of that failure were rated. In Experiment 2, controllable and uncontrollable causes of a social transgression were given, and children rated the anticipated anger of the “victim” and their intention to withhold or reveal the cause. In Experiment 3, effects of perceived causality and related emotions of anger and sympathy (pity) with regard to helping behaviour were investigate…

Estado nutricional en ancianos con fractura de cadera
1997
Presentamos un estudio prospectivo del estado nutricional en 55 pacientes con fractura de cadera, con una edad media de 83 años, y que fueron sometidos a intervención quirúrgica. La valoración del estado nutricional se realizó en base a las determinaciones serológicas de albúmina, prealbúmina, colesterol, transferrina, proteínas totales y linfocitos totales. Treinta y nueve pacientes con fractura (71%) presentaron malnutrición en el momento de su ingreso en el hospital frente a solamente 6 sujetos del grupo control (13%); tras la operación todos los pacientes presentaron malnutrición. Nuestros hallazgos sugieren que la malnutrición puede ser un factor predisponente a la fractura de cadera. …

Numerical experiments with a parallel fast direct elliptic solver on Cray T3E
1997
A parallel fast direct O(N log N) solver is shortly described for linear systems with separable block tridiagonal matrices. A good parallel scalability of the proposed method is demonstrated on a Cray T3E parallel computer using MPI in communication. Also, the sequential performance is compared with the well-known BLKTRI-implementation of the generalized. cyclic reduction method using a single processor of Cray T3E.

Demixing of Mixed Micelles. Thermodynamics of Sodium Perfluorooctanoate−Sodium Dodecanoate Mixtures in Water
1997
Conductivity, density, heat capacity, enthalpy of dilution, and osmotic coefficient measurements of water−sodium perfluorooctanoate (NaPFO)−sodium dodecanoate systems were carried out as functions of the surfactants' total molality (mt) at different mole fractions (XNaPFO). From conductivity data, the critical micelle concentration (cmc) and the degree of ionization (β) of the micelles were derived. The cmc's of the micelles are higher than those of the pure surfactants while β depends linearly on XNaPFO. At a given mole fraction, the apparent molar volume (VΦ) and heat capacity (CΦ) of the mixture increases and decreases monotonically with mt, respectively. From data in the premicellar reg…

La 'libertad' en el Humanismo renacentista y la Reforma
1997
Exposición del mapa de posiciones que en torno al debate filosófico-teológico entre el determinismo y la libertad (el servo arbitrio frente al libre arbitrio o albedrío) se dieron en Europa en los siglos XV y XVI, un momento central en la historia de esta confrontación, que llevó a preparar un gran arsenal argumentativo de enorme influencia.
ImageRover: A Content-Based Image Browser for the World Wide Web
1997
ImageRover is a search-by-image-content navigation tool for the World Wide Web (WWW). To gather images expediently, the image collection subsystem utilizes a distributed fleet of WWW robots running on different computers. The image robots gather information about the images they find, computing the appropriate image decompositions and indices, and store this extracted information in vector form for searches based on image content. At search time, users can iteratively guide the search through the selection of relevant examples. Search performance is made efficient through the use of an approximate, optimized k-d tree algorithm. The system employs a novel relevance feedback algorithm that se…
Role of nitrogen fixing microorganisms in increasing the productivity of agricultural plants
1997
The paper presents data on studying the most favourable conditions for development and active physiological activity of nitrogen-fixing microorganisms (increasing the quantity of nitrogen-fixing microorganisms in soil with help of bacterial fertilizers and selection of agrotechnical methods, plant selection on increasing of symbiotic nitrogen-fixing intensity, etc.). the dependence of nitrogen-fixing level on complementarity of macro- and micro-symbiont and their adaptive properties has been determined. The scheme of the principal stages of legume and nodule bacteria selection for the increasing of nitrogen-fixing intensity was elaborated as the result of theoretical work with selections of…

Didáctica de las ciencias experimentales y sociales
1997
Se analiza la consolidación de la enseñanza de la historia en Gran Bretaña después de la Segunda Guerra Mundial. Durante este período la enseñanza de la historia en este país giró en torno a la necesidad de encontrar criterios selectores de contenidos que garantizaran la correspondencia de estos últimos años con nuevas exigencias que procedían de los avances producidos en muy diversos campos: sociológico, psicopedagógico y sobre todo, epistemológico. A grandes rasgos destacaron dos cuestiones relacionadas con la selección de contenidos: la defensa de un entendimiento más dinámico y formalista de la enseñanza y el auge de modelos didácticos tecnicista, ademá de considerar el instrumentalismo…

Adsorption of functionalized biomembrane vesicles on crystalline surfaces monitored by FTIR- and Surface Enhanced FTIR Spectroscopy
1997
A special class of integral membrane proteins are the ion channels. To use them for technical purposes they have to be transferred with their lipid surrounding onto artificial materials, i.e. crystals. In this study we used vesicles containing the nicotinic acetylcholine receptor (nAChR) and porin. The first allows the ligand gated flow and the second allows the voltage gated flow of cations across the membrane. We used ATR-FTIR spectroscopy and surface enhanced FTIR techniques (SEIRA) to monitor the direct contact of the vesicles with the crystal.
