Cleaning of stone materials in the Cathedral de Valladolid (Spain)

R. Fort、M. C. López de Azcona、F. Mingarro2000-06-01Materiales de Construccion

Two types of black crusts showing gypsiferous and calcareous compositions are recognized on the front-walls of the Valladolid Cathedral. On the basis of several petrophysical parameters, in particular compacity, sorption and desorption kinematics of carbonate rocks used building the cathedral, we conclude that the mos…

Rheology of cement mixtures with dolomite filler

P. J. Martínez de la Cuesta、E. Rus Martínez、F. Díaz Molina 等 4 位作者2000-06-01Materiales de Construccion

This experimental program has studied the behavior of fresh paste made up from cements mixed with dolomite filler. Through prior experiments the starting point is obtained for the designs 22 and 23 factorials. With these designs the governing equations are established that influence the specific surface of the filler,…

Mortars and treatments in the restoration of the Altarpiece of the High Altar of the Pilar Basilica

M. P. Luxán、F. Dorrego、R. Sotolongo2000-06-01Materiales de Construccion

The altarpiece of the Assumption of Mary is located in the High Altar of the Pilar Basilica in Zaragoza and is one of the most important works of the Spanish Artistic Heritage. The work, sculptured in alabaster, was carried out between 1509 and 1518 by Damián Forment. The present paper covers the guidelines for the de…

Morteros a base de suelos. Caracterización

J. L. Cabrera、Y. Fernández Collazo、N. González Ramírez 等 4 位作者2000-06-01Materiales de Construccion

The goals states in this work are included in a study with different volumetric dosifications, using different kinds of soils like aggregates, and cement and lime like binding material to be used in mansonry mortars. The mortars were caracterized by determining the R a/c, Rf and Re to different ages, R adh. to 28 days…

Effect of pollutant gases on electrical insulators deterioration

A. Zamarad、S. Martínez-Ramírez、G. E. Thompson 等 4 位作者2000-06-01Materiales de Construccion

In this work ceramic materials as electrical insulators have been exposed in laboratory-based chambers. Water contact angle and FTIR of the surface before and after pollutant exposures have been studied. The results indicated that the reaction between the policrete and the atmospheric pollutant produce some salts depo…

Chaotic Mixing Analyses by Distribution Matrices

Anderson Patrick D.、Meijer Han E. H.2000-06-01Applied Rheology

Distributive fluid mixing in laminar flows is studied using the concept of concentration distribution mapping matrices, which is based on the original ideas of Spencer & Wiley [1], describing the evolution of the composition of two fluids of identical viscosity with no interfacial tension. The flow domain is divided i…

Dynamic Mechanical Freezing Points of Cosmetic O/W Emulsions and Their Stability at Low Temperatures

Hetzel Frank、Nielsen Jens、Wiesner Stefan 等 4 位作者2000-06-01Applied Rheology

To develop cosmetic products quickly and effectively, developers need reliable test methods for evaluating product stability. Phenomena that determine the stability of cosmetic emulsions include phase transitions taking place in the relevant application and storage temperature range. The tendency of ingredients to cry…

Fluid Immobilization – A Structure-Related Key Mechanism for the Viscous Flow Behavior of Concentrated Suspension Systems

Erich J. Windhab2000-06-01Applied Rheology

Abstract The role of fluid immobilization (FIM) is not only of great importance for solid food systems with respect to their stability, but is also a crucial factor for the rheological behaviour of suspension systems [1]. Besides the fluid binding mechanisms known for porous solids an additional hydro-dynamically indu…

Structure correlation study of four-coordinate copper(I) and (II) complexes

Paul R. Raithby、G.P. Shields、Frank H. Allen 等 4 位作者2000-06-01Acta Crystallographica Section B Structural Science

The geometries of four-coordinate CuI and CuII complexes in the Cambridge Structural Database (CSD) have been analysed systematically and compared using symmetry-deformation coordinates and principal component analysis. The observed stereochemistries have been rationalized in terms of the d-electron configurations, in…

Nano-assembly of glucose oxidase on thein situself-assembled films of polypyrrole and its optical, surface and electrochemical characterizations

Manoj K. Ram、M. Adami、Sergio Paddeu 等 4 位作者2000-06-01Nanotechnology

An in situ self-assembly technique with nanometre control over thicknesses and multilayered structures was used to manufacture the ultrathin films of polypyrrole (PPY). The PPY film was deposited on a polyanion, poly(styrene sulfonate) (PSS) modified surface as a function of time, previously PSS had been deposited on…
