Radula synthesis by three species of iron mineralizing molluscs: production rate and elemental demand [PDF]

open access: yes, 2008
A cold-shock technique was used to determine radula production rates for the chitons Acanthopleura hirtosa and Plaxiphora albida, and for the limpet Patelloida alticostata, which replaced their radular teeth at rates of 0.40, 0.36 and 0.51 rows d-1 ...

Atypical gold mineralization in an orogenic setting : the Bohaun Deposit, western Irish Caledonides [PDF]

open access: yes, 2011
The Bohaun gold deposit in County Galway, western Ireland is located in the Caledonian orogenic belt, proximal to a major accretionary boundary. The mineralization is hosted in a normal extensional fault, representing a zone of repeated extension and ...

Correction to: Size matters: biochemical mineralization and microbial incorporation of dicarboxylic acids in soil [PDF]

open access: yes, 2022
The transformation and turnover time of medium- to long-chain dicarboxylic acids (DCA) in soil is regulated by microbial uptake and mineralization. However, the chain length of n-alkyl lipids may have a remarkable influence on its microbial utilization ...

An investigation of the duration of phosphorous fertilization effects on phosphorous and nitrogen cycling patterns of Pinus elliottii plantations in the southern Cape [PDF]

open access: yes, 1992
Includes bibliographical references.The effects of phosphorus fertilization and its duration of impact on nutrient cycling patterns in Pinus elliottii plantations were investigated by examining soil phosphorus and nitrogen turnover and litterfall in a 8,

Electrochemical incineration of cresols: A comparative study between PbO2 and boron-doped diamond anodes [PDF]

open access: yes, 2009
The electrooxidation of aqueous solutions containing 5 mM of o-, m- and p-cresol at pH 4.0 has been investigated using a flow filter-press reactor with a boron-doped diamond (BDD) under galvanostatic electrolysis. All cresols are degraded at similar rate

The contribution of mineralization to grassland N uptake on peatland soils with anthropogenic A horizons [PDF]

open access: yes, 2011
Peatland soils contain large amounts of nitrogen (N) in the soil and mineralization can contribute substantially to the annual mineral N supply of grasslands. We investigated the contribution of N mineralization from peat with respect to the total annual

Ultrastructure of the epithelial cells associated with tooth biomineralization in the chiton Acanthopleura hirtosa [PDF]

open access: yes, 2009
The cusp epithelium is a specialized branch of the superior epithelium that surrounds the developing teeth of chitons and is responsible for delivering the elements required for the formation of biominerals within the major lateral teeth.

Cretaceous subduction-related magmatism and associated porphyry-type Cu–Mo prospects in the Eastern Pontides, Turkey: New constraints from geochronology and geochemistry

open access: yes, 2016
This study focuses on the Elbeyli-Ordu, Emeksen-Giresun, Güzelyayla-Trabzon and Ulutaş-Ispir porphyry-type prospects located in the Eastern Pontides, Turkey.

Deficiency of annexins A5 and A6 induces complex changes in the transcriptome of growth plate cartilage but does not inhibit the induction of mineralization [PDF]

open access: yes, 2009
Initiation of mineralization during endochondral ossification is a multistep process and has been assumed to correlate with specific interactions of annexins A5 and A6 and collagens.

Exploring the oxygen sensitivity of wetland soil carbon mineralization

open access: yes, 2019
Soil oxygen availability may influence blue carbon, which is carbon stored in coastal wetlands, by controlling the decomposition of soil organic matter.
