This study investigated the effect of vegetation plant roots on stability cover slopes solid waste landfills. A large direct shear test and a root tensile strength were conducted to quantify rooted soil revegetation plants increment in as method protect slope In test, an increase ground with presence was observed, reinforcement proposed literature modified by analyzing correlation between diame...

in this paper an adaptive pid controller for wind energy conversion systems (wecs) has been developed. theadaptation technique applied to this controller is based on reinforcement learning (rl) theory. nonlinearcharacteristics of wind variations as plant input, wind turbine structure and generator operational behaviordemand for high quality adaptive controller to ensure both robust stability an...

We present the management of a case of Type II dens invaginatus in a mandibular premolar with a large invagination in the coronal third of the root on mesial aspect of the crown in proximity of cementoenamel junction significantly compromising the strength of the crown structure. We describe in detail the various measures taken to assess the internal tooth structure destruction and enhance the ...

When a method of intracoronal reinforcement is selected, many factors must be weighed. The hazards include (1) the induced stresses and the risk of fracture during placement of the dowel, (2) the probability of root perforation during post space preparation, (3) the wedging action of tapered dowels, and (4) the incidence of fracture with self-threading pins in devitalized teeth. The amount of t...

AIM To assess how the various methods of intracanal reinforcement (short root canal posts) performed in their clinical and radiographic outcomes for restoring grossly broken down primary anterior teeth after pulpectomy for 1 year or longer follow-up period. MATERIALS AND METHODS Literature search of electronic databases (Sept 2013) and various journals (1980-Sept 2013) using medical subject h...
