Introduction. Health care services require nurses , who are critical thinkers,with high learning Skills, who can solve problems for which there are often no standard solutions. Therefore, a change in the way teachers teach merits consideration. Frost argued that pbl equiped nurses with skills demanded by society. Methods. With above consideration, this research , that is a semi-exprimenta...

optimal design of cantilever reinforced concrete retaining wall can lead considerable cost saving if its involvement in hill road formation and railway line formation is significant.  a study of weight reduction optimization of reinforced cantilever retaining wall subjected to a sloped backfill using differential evolution algorithm (dea) is carried out in the present research.  the retaining w...

In view of the deformation and instability law hard roof without side filling retaining roadway, based on systematic construction analysis force bearing model roadway structure, this article proposes control mechanical calculation method retaining, which takes anchor beam key block above to form cantilever together, with solid coal as foundation support. The research practice show that under co...

We describe a parallel annotation approach for PubMed abstracts. It includes both entity/relation annotation and a treebank containing syntactic structure, with a goal of mapping entities to constituents in the treebank. Crucial to this approach is a modification of the Penn Treebank guidelines and the characterization of entities as relation components, which allows the integration of the enti...

Scaffolds are defined as the core structure of a molecule connecting different substituents or functional groups. Defining bioisosteric alternative scaffolds for lead structures is an important task in drug design to improve e.g. the activity, bioavailability or selectivity of the structures concerned [1]. In this context, bioisosteric replacement means changing the scaffold structure while ret...

Abstract: The design of retaining walls requires the complete knowledge of the earth pressure distribution behind the wall. Due to the complex soil-structure effect, the estimation of earth pressure is not an easy task; even in the static case. The problem becomes even more complex for the dynamic (i.e., seismic) analysis and design of retaining walls. Several earth pressure models have been de...
