Rainfall erosivity is the potential ability for rainfall to cause soil loss. The purpose of this study was to estimate the rainfall erosivity index for the Ghana Atomic Energy Commission site in order to compute the surface erosion rate. Monthly rainfall data, for the period 2003-2012 were used to compute annual rainfall erosivity indices for the site, using the Modified Fournier index. Values ...

An 85-year-old man with a high risk for open heart surgery underwent a percutaneous closure of an atrial septal defect that lacked adequate aortic and superior rims. To avoid the risk for erosion, a Figulla Flex II ASD occluder was selected for the procedure. Implantation was successful, and no complications were observed during the 6 months of follow-up.

The Water Erosion Prediction Project (WEPP) model is a physically-based soil erosion tool developed to predict runoff and erosion. Databases for forest soil, vegetation, and climate conditions have been developed. Background sediment may be generated annually from undisturbed forests, and occasionally following wildfire. In some cases, it may be appropriate to include sediment from essential fo...

While oral agents are currently suggested for the initial treatment of erectile dysfunction, penile prosthesis implantation (malleable or inflatable) is accepted as a third-line therapy if intracorporeal injection and intraurethral treatment fail as a secondary choice. Urethral erosion of the malleable penile prosthesis is a well-known complication, mostly due to the indwelling catheter. We rep...

Development of coastal area for various economic activities such as agriculture, tourism and industrial facilities and recreational areas is inevitable. These activities may indirectly contribute to accelerated coastal erosion. Economic activities imply a pressure on natural environment for the case of coastal zones. In addition, environmental changes such as climate change, tidal wave, wind an...

Due to the effect of global change, the potential risk of natural hazards occurring in alpine areas is expected to increase to an even higher risklevel than has been recorded during the last century. These global changes potentially also have distinct influences on fluvial processes in torrents causing erosion on slopes and riverbanks in forested areas. Dating the time of root exposure along ri...

Dental erosion (erosive tooth wear) is the result of a pathologic, chronic, localized loss of dental hard tissue that is chemically etched away from the tooth surface by acid and/or chelation without bacterial involvement. Acids of intrinsic (gastrointestinal) and extrinsic (dietary and environmental) origin are the main etiologic factors. Tooth wear including dental erosion is not a new phenom...

AIM The aim of the study was to examine the association between telomere erosion and periodontitis in a long-standing prospective cohort study of New Zealand adults. Specific hypotheses tested were as follows: (i) that exposure to periodontitis at ages 26 and 38 was associated with accelerated leucocyte telomere erosion and (ii) that accelerated leucocyte telomere erosion was associated with hi...

INTRODUCTION Hydrochloric acid (HCl) from the gastric juice is the only source of intrinsic acid, which can reach the oral cavity in cases of gastroesophageal reflux or chronic vomiting, enhancing the risk of dental erosion. AIM Compare the effects of mouthrinses with different active agents in the prevention of initial dental erosion caused by HCl. SUBJECTS AND METHODS Casein (CAS at 0.2%)...
