OBJECTIVE The aim of this study was to analyze the impact of green tea on dentin erosion. MATERIALS AND METHODS Twelve extracted sound human premolars were immersed in Coca Cola with a pH of 2.8 for 5 minutes. The surface microhardness was measured with a Knoop diamond under a load of 50gr/10s. The teeth were immersed in green tea (Camellia sinensis) solution for one minute. The microhardness...

In this paper, a new Fuzzy Morphology (FM) based on the GeneralizedDempster-Shafer Theory (GDST) is proposed. At first, in order to clarify the similarity ofdefinitions between Mathematical Morphology (MM) and Dempster-Shafer Theory (DST),dilation and erosion morphological operations are studied from a different viewpoint. Then,based on this similarity, a FM based on the GDST is proposed. Unlik...

BACKGROUND Banded-gastric bypass is a highly effective bariatric procedure, yet the possibility of band erosion remains a significant drawback. Surgical removal of eroded bands may be associated with significant morbidity. In this study, we assess the efficacy and safety of a solely peroral endoscopic approach for the management of eroded bands in patients with a banded-gastric bypass. MATERI...

Abstract Water erosion could cause wide and serious soil organic carbon (SOC) loss, but differences in SOC loss enrichment sediments among red soil, black loess China have received less attention. This study investigates the transport of generation regulation runoffs during process by collecting data from indoor or outdoor artificial simulated rainfall experiments selecting typical regional int...

Hyaline cartilage was obtained from patients undergoing synovectomy of the knee joint for rheumatoid arthritis. Eroded cartilage from beneath the invading pannus and relatively normal cartilage from the same joint were maintained in organ culture for three days. During the first 48 hours in culture the explants were exposed to 35SO4 in the medium. The equivalent layers of normal and eroded cart...

In search for an efficient means of building up the carbon stock, improving fertility levels and aggregate stability tropical soils optimum crop yield, a field study was carried using different biochars comparing effects with inorganic fertilizer. The were palm bunch biochar (PBB), saw dust (SDM) rice mill husk (RMHB). Treatments consisted 10 t/ha + 0.25t/ha poultry manure (T1), (T2), (T3), 500...

Digital mapping was applied for a key site located at the Southern Cis-Ural region near Ufa city (the Republic of Bashkortostan, Russia). The digital soil map (DSM) created using open-source GIS software packages and compared to conventional (CSM) one. As input parameters, we used standard morphometric values topography field descriptions soils, including authors’ data. DSM same scale (1:25,000...

Soil loss through wind and water erosion is an ongoing problem in semiarid regions. A thin layer of top soil loss over a hectare of cropland could be corresponding to tons of productive soil loss per hectare. The objectives of this study were to evaluate the influence of beef feedlot manure, tillage and legume grass mixtures on changes in soil quality and nutrient components. The study was init...

The northern region of Algeria is experiencing a real threat to the spatial extension soil erosion. Oued Bouhamdane watershed, part this region, brings together all natural and anthropogenic conditions that accelerate its degradation. This study based on use remote sensing GIS map erosion in watershed north-eastern Algeria, using Gavrilovic equation. combination data from different sources fiel...
