Soil micromorphology for construction science: the mortar archaeometry [PDF]

open access: yes, 2012
Micromorphology revealed in depth evaluation of materials particularly soil micromorphology yielded numerous data on processes such as formation, neoformation and transformation of minerals and microstructure in soils, pottery and construction materials.

Soil Micromorphologic Features of Holocene Surface Weathering and a Possible Late Quaternary Buried Soil, Northwest Arkansas [PDF]

open access: yes, 1989
Micromorphologic features of an alfisol developed in White River alluvium near Fayetteville, Arkansas are typical for this soil order. The A horizon has a relatively high organic matter content and an abundance of quartz sand grains with a silt and clay ...

Recognition of micro-scale deformation structures in glacial sediments - pattern perception, observer bias and the influence of experience [PDF]

open access: yes, 2013
It is a scientist's mission to try to remain unbiased. However, certain factors play a role in scientific analyses that are not controlled by conscious thought.

Leaf Micromorphology Aids Taxonomic Delineation within the Hypervariable Genus Metrosideros (Myrtaceae) on O\u27ahu

open access: yes, 2018
Variation in leaf micromorphology can aid delimitation of taxonomically difficult groups. The woody genus Metrosideros (Myrtaceae) dominates Hawai\u27i\u27s native forests and comprises striking, predominantly infraspecific, macromorphological variation,

Critical current density and microstructure of iron sheathed multifilamentary Sr1-xKxFe2As2/Ag composite conductors

open access: yes, 2015
Iron-based superconductors have been considered to be very promising in high-field applications, for which multifilamentary wire and tape conductors with high mechanical strength are essential.

Synthesis and properties of a new AB-cross-linked copolymer membrane system [PDF]

open access: yes, 1993
The alcohol permeability and permselectivity properties as well as the morphology of membranes made of a newly developed AB-cross-linked copolymer system composed of elastomeric and glassy components were investigated.

Breast calcification micromorphology classification

open access: yesThe British Journal of Radiology, 2022
Objectives: The importance of consistent terminology in describing the appearance of breast calcifications in mammography is well recognised. Imaging of calcifications using electron microscopy is a globally growing field of research. We therefore suggest that the time is ripe to develop a lexicon of terms for classifying the micromorphology of breast ...

Micromorphology and microstructural analysis of polyphase deformation of tills, West Runton [PDF]

open access: yes, 2011
Glacially deformed sediments have been studied intensely since the 1970’s (van der Meer and Menzies, 2011), and with this, the use of micromorphology as a component technique (Menzies and Maltman, 1992; van der Meer, 1993; Menzies, 2000; Phillips and ...

Soils and paleosoils of the Galapagos Islands : what we know and what we don't know, a meta-analysis [PDF]

open access: yes, 2014
Accessible information on Galapagos soils is very limited. Much of the existing, although still scarce, information is several decades old and not easily retrieved. The aim of this paper is to present a critical synthesis.
