Alteration mechanisms on the stones of the Catedral of Granada, Spain
The diverse alteration mechanisms which operate on the stony materials of the Granada Cathedral have been analized. The water action, anthropogenic influence, thermic oscillations, incompatibility factors, seismicity and biological factors have been considered.

Origin of zeolite cements in the Miocene sandstones, North Tejon oil fields, California
Abstract Zeolite cement zoning from heulandite via heulandite + laumontite to laumontite is found in Miocene volcaniclastic sandstones at the North Tejon Oil Field, southern San Joaquin basin, California. The zeolite transition occurs at the depth range from 2703-2743 m (present temperature range: 90-92 degrees C). He…
Derivation of a general three-dimensional crack-propagation law: A generalization of the principle of local symmetry
We derive a general crack-propagation law for slow brittle cracking, in two and three dimensions, using discrete symmetries, gauge invariance, and gradient expansions. Our derivation provides explicit justification for the ``principle of local symmetry,'' which has been used extensively to describe two-dimensional cra…
Polyaniline Secondary Cells with Ambient Temperature Molten Salt Electrolytes
An Al/polyaniline (PAn) powder secondary cell with an or an electrolyte has been investigated. The configuration of the Al/PAn secondary cell with an acidic electrolyte was: open‐circuit voltage , , . A 24% increase in the discharge capacity over a BPC system electrolyte is obtained. The difference was attributed to t…
Genesis and transformation of minerals in the formation of red (Alfisols) and black (Inceptisols and Vertisols) soils on Deccan basalt in the Western Ghats, India
SUMMARY Six noncalcareous pedons from the basaltic terrain of the Western Ghats in Maharashtra, India, were identified for the present study. Of these, two red‐soil pedons (Typic Haplustalfs) and one black‐soil pedon (Vertic Ustropept) are from the Bhimashankar plateau at an elevation of 1000 m above mean sea level, e…
The Influence of Fumed Silica Properties on the Processing, Curing, and Reinforcement Properties of Silicone Rubber
Abstract The present study uses a commercial heat cured silicone rubber formula (including a process aid) and mixing techniques to investigate the effect of varying fumed silica properties—including load, surface area, silica structure level, and surface pretreatment levels—on the rubber processing, curing, and cured…
Coordination polymerization of lactides, 4. The role of transesterification in the copolymerization of L , L ‐lactide and ε‐caprolactone
Abstract Two modes of transesterification in copolymerization of L , L ‐lactide with ε‐caprolactone in the presence of initiators containing Al and Zn were found. The quantitative analysis of the contributions of both types of transesterification reactions is revealed. The transesterification ability of initiators con…
Biological response of intramedullary bone to poly‐L‐lactic acid
Abstract This study focuses on examining the biological response of intramedullary bone to poly‐ L ‐lactic acid (PLLA), particularly during the PLLA degradation phase. To study the influence of spherical crystals (spherulites) of PLLA on intramedullary bone response, two different types of PLLA coupon, with and withou…
