block ramps are hydraulic structures which are commonly used in river restoration projects. especially in the last few decades, the use of this type of structures have become more and more popular. they furnish a correct balance between the hydraulic functioning and the environmental care, as they minimize the impact on the environment in which they are located. in addition, they can be conside...

Symmetric collision between two identical plates has yielded successful theoretical models for the jetting process. Consequently, assessment of impact jetting at planetary scales has been largely based on the theories developed for such specific types of collisions. Little experimental work has been done, however, to measure both temperature and target-to-projectile mass ratio of jetting create...

Oral lichen planus (OLP) is a chronic inflammatory disease with different clinical presentations that can be classified as reticular or atrophic-erosive. Sixty-two OLP patients were studied to evaluate the clinical-pathologic characteristics of their OLP lesions and to investigate possible differences in their biological behavior. The most common clinical presentation was the reticular type (62...

OBJECTIVE This in situ/ex vivo study assessed the erosive potential of a light cola drink when compared to a regular one. METHODS During 2 experimental 14-days crossover phases, eight volunteers wore palatal devices with 2 human enamel blocks. The groups under study were: group light, erosive challenge with light cola drink and group regular, erosive challenge with regular cola drink. During ...

EPDS: erosive pustular dermatosis of the scalp INTRODUCTION Erosive pustular dermatosis of the scalp (EPDS) is an uncommon condition that is reported after local injuries including burns, cryotherapy, radiation therapy, photodynamic therapy, skin grafts, and hair transplantation as well as topical medication treatments including retinoids, imiquimod, and 5fluorouracil. We present a case of eros...

BACKGROUND Little attention has been directed towards identifying the relationship between physical exercise, dental erosive wear and salivary secretion. The study aimed i) to describe the prevalence and severity of dental erosive wear among a group of physically active young adults, ii) to describe the patterns of dietary consumption and lifestyle among these individuals and iii) to study poss...

PURPOSE Erosive esophagitis frequently develops after successful Helicobacter pylori eradication. Since salivary secretion of epidermal growth factor (EGF) plays a crucial role in the pathogenesis of gastroesophageal reflux disease, the current study objective was to find out whether erosive esophagitis development after Helicobacter pylori eradication is associated with the secretion of EGF in...
