Soil organic matter contains fractions that range from very active to passive, relative to microbiological activity Soil organic matter (SOM) contains fractions that range from very (Schimel et al., 1985), suggesting that classification of active to passive, relative to microbial-driven ecosystem processes and functions. A classification system is needed that can test the hypothesis SOM forms m...

Dunes are present in nearly all fluvial channels and are vital in understanding sediment transport, deposition, and flow conditions during floods of rivers and estuaries. This information is pertinent for helping developing management practices to reduce risks in river transportation and engineering. Although a few recent studies have investigated the micromorphology of a portion of the Yangtze...

The purpose of this study was to explore the relationship between tendon micro-morphology quantified from a sonogram and tendon mechanical characteristics measured in vivo. Nineteen adults (nine with unilateral Achilles tendinosis) participated. A commercial ultrasound scanner was used to capture longitudinal B-mode ultrasound images from the mid-portion of bilateral Achilles tendons and a cust...

Two new species of Psyllocarpus sect. Psyllocarpus, P. itakangapyra Sobrado, J.A.M.Carmo & R.M.Salas sp. nov. and vianae nov., from the “campo rupestre” state Minas Gerais, southeastern Brazil, are here described illustrated. We provide comments on their distribution, habitat, preliminary conservation status, discuss taxonomy. In addition, we analyse floral, fruit, seed micromorphology, as ...
