Laboratory scale studies have repeatedly reported high P-retention in slag, a by-product of the steel manufacturing industry. Thus, it has emerged as a potential material to increase P-removal from constructed wetlands (CWs). However, several limitations were highlighted by field experiments, including the high pH of treated water and clogging. We hypothesized that the addition of sedimentary r...

Lime production is a process that entail complex material and energy transport and chemical reaction. Efficient lime production processes are realized via well structured design models approach . Simulation of such process design models essentially provides Information on the attractive features and technical limitations of such processes which serves as guide for normal operations. The choice ...

The attachment of the psammophytic alga Caulerpa mexicana Sond. ex Kütz., a coenocytic green alga, to crushed CaCO3 particles was examined utilizing the scanning electron microscope and fluorescently tagged antivitronectin antibodies. Plants attached to the substrate through morphologically variable tubular rhizoidal extensions that grew from the stolon. In this study, we describe two means of ...

Yes and no. These synthetic stones are in fact re-agglomerated materials. The process is explained in more detail later in the book. Basically, the principle is as follows: starting with a mineral substance such as eroded, disintegrated or naturally disaggregated rock – such as the limestone found everywhere in northern France – we give it a compact structure using a binder, a geological glue t...

three well - known source rocks of the zagros basin and the persian gulf are mesozoic in age.the jurassic sargelu, albian kazhdumi and neocomian-coniacian garau formations have charged the cretaceous reservoirs of this area. the northwest part of the persian gulf is strongly influenced by two major n-s trending paleohighs (hendijan- bahregansar-regesafid-izeh and kharge- mish) and surrounding p...

The Mississippian Salem Limestone, from which dimension stone is quarried in Indiana, is principally a calcarenitic rock formed of fossil bryozoans, echinoderms, and specimens of Endothyra. Numerical associations of the fossils, binding materials, oolitically coated fossils, and voids were determined by counting points on the surfaces of 278 thin sections of the limestone. Median sizes, coeffic...

The assembly of fungal communities on stone materials is mainly influenced by the differential bioreceptivity of such materials and environmental conditions. However, little is known about the role of fungal interactions in the colonization and establishment of fungal species. We analyzed the effects of intra- and interspecific interactions between 11 species of fungi in oligotrophic and copiot...

Vertical variation in sorption and mineralization potential of mecoprop (MCPP), isoproturon and acetochlor were investigated at low concentrations (μg-range) at the cm-scale in unsaturated sub-surface limestone samples and saturated sandy aquifer samples from an agricultural catchment in Brévilles, France. From two intact core drills, four heterogenic limestone sections were collected from 4.50...
