This article describes the results of a study on Zn-Pb heap, which is located in center city Ruda ?l?ska. The heap dates back to 19th century but was rediscovered 21st and abandoned. Located city, it eroded contributes spreading pollutants. authors performed components dump using microscopic observations geochemical analyses. indicate that are mobile, mainly due infiltration meteoric waters aff...

Soil erosion by water is the most important global environmental problem. A modern system for assessing and monitoring soil erosional degradation should be based on use of remote sensing data. This raises issue correct data decoding. The article proposes a method visual interpretation eroded soils according to Sentinel image obtained in visible range. authors give some combinations decoding sig...

AIM To evaluate the bond strength of one etch-and-rinse adhesive system and one resin-modified glass ionomer cement to sound and eroded enamel. MATERIALS AND METHODS Forty-eight bovine incisors were embedded in acrylic resin and ground to obtain flat buccal enamel surfaces. Half of the specimens were submitted to erosion challenge with pH-cycling model (3x/cola drink for 7 days) to induce ero...

With the changing climatic scenario, reduction in CO2 atmosphere will be viable solution to reduce air temperature as well production of sensitive crops. Carbon sequestration is a new area for researchers. It process by which carbon dioxide taken out from Earth's and afterward stored into soils. Most soils agroecosystems having lower C pool than under natural vegetation cover. Some severely dep...

An Analysis on Soil Properties on Predicting Critical Hydraulic Gradients for Piping Progression in Sandy Soils By Tammy Jacobson, Master of Science Utah State University 2013 Major Professor: Dr. John Rice Department: Civil and Environmental Engineering Piping is a form of internal erosion in which soil particles are eroded at a seepage exit location due to the forces imposed on the particles ...

The objective of this work is the pedological characterization soils in watersheds Oueds Nekôr and Ghiss. Several profiles were identified sampled for Physico-chemical sedimentological analyses (color index, magnetic susceptibility, pH, granulometry, water content, organic matter, carbonates). question are roughly characterized by a soft diversified lithology, sparse vegetation cover, semi-arid...

Abstract The Oued Srou watershed located in the Middle Atlas Mountain of Morocco has been a subject serious soil erosion problems due to combination natural factors and anthropic activities. Therefore, hazard assessment mapping can be handy initiate remedial measures area. In this study, improved Erosion Potential Model (EPM) integrated with GIS remote sensing techniques is employed map assess ...

OBJECTIVE To evaluate the necessity of reconstructing the eroded bony boundaries after mucocele marsupialization when the mucoperiosteum has been spared. STUDY DESIGN Retrospective review of 308 patients treated for a sinonasal mucocele. Of these, 116 showed areas of bone reabsorption in their preoperative computed tomography (CT) scan. METHODS Of 116 patients showing one or more areas of b...

The present study assessed the effects of abrasion, salivary proteins, and measurement angle on the quantification of early dental erosion by the analysis of reflection intensities from enamel. Enamel from 184 caries-free human molars was used for in vitro erosion in citric acid (pH 3.6). Abrasion of the eroded enamel resulted in a 6% to 14% increase in the specular reflection intensity compare...
