Best Practices: Retaining Registered Nurses
<p>The U.S. is currently faced with a nursing shortage that has global implications. Both intrinsic and extrinsic factors encompass multiple variables that directly contribute to the current shortage. These issues have been shown to have a direct impact on overall organizational commitment. Current …

Renal dopamine and salt-retaining states
… in diabetes mellitus as an example of a sodium-retaining state, and compared with that in a matched normal control group. A decreased ASA activity was anticipated, given the blunted dopamine excretion observed in many sodium-retaining states, however an unexpected increase in activity in the …

Retaining Distinction; Restructuring a Small Town
This urban thesis proposes the restructuring of a small railroad town that concentrates on vertical growth, publicly shared urban spaces, and the distinction between town and country. A new organization of building types reflects the modern lifestyle of the town which focuses on the integration of …

Movements of footings and retaining walls
… a simple procedure for calculating movements of retaining walls due to the weight of backfill. The accuracy and reliability of twelve methods of estimating settlements of footings on sand and gravels were examined by comparing calculated settlements with the measured values. Eleven of the methods …

Retaining principals in high poverty public schools
The turnover of school principals in high-poverty schools is having a profound impact on student achievement. Principal turnover influences teacher turnover, sustainability of school improvement efforts, and generates increased financial costs to the district. Research cites the demands of the job, …

Three dimensional behavior of retaining wall systems
… interaction (SSI) features of selected earth retaining walls utilizing the nonlinear finite element method (FEM). These 3-D features are not explicitly incorporated in conventional two-dimensional (2-D) procedures that are commonly used to design these retaining walls. The research objective …

Seismic performance of single-propped retaining walls
… the dynamic performance of single-propped retaining walls in dry sand under different seismic excitations using the finite difference software FLAC v7.0 (Itasca). The structure comprises two reinforced concrete diaphragm walls connected by a row of cross-lot struts that is used to support a …

Reliability-based design of a retaining wall
A retaining wall is subject to various limit states such as sliding, overturning and bearing capacity, and it can fail by anyone of them. Since a great deal of uncertainty is involved in the analysis of the limit states, the use of detenninistic conventional safety factors may produce a misleading …

Deformation prediction of geosynthetic reinforced soil retaining walls
… the deformation of geosynthetic reinforced soil retaining walls is presented. This investigation included laboratory testing of geosynthetic reinforcements and geosynthetic reinforced cohesionless soils, and finite element analysis of reinforced soil retaining walls.Two sands, two polypropylene …

Retaining students: is it for gaining or restraining?
… This study was conducted to determine whether retaining students benefits or hinders their chances of academic success. Once the retained students in Grades 6-8 were identified, the reasons for their retentions (located in the student's personal files) were investigated and recorded. …

Evaluating Performance of Hybrid Geosynthetic-Reinforced Retaining Walls
Geosynthetic-Reinforced Retaining (GRR) walls have been extensively used in highway projects. A novel GRR wall was proposed to mitigate the problems (e.g. high connection stress) resulting from the relatively large spacing of primary reinforcement. This new GRR wall has secondary reinforcement …

Diagnosis of arcing in retaining rings of turbogenerators
Retaining rings are an important and most highly stressed component of the entire turbogenerator system. Arcing in retaining rings is a very serious problem and could easily escalate to a full-blown failure. In this project we diagnose arcing in the retaining rings. We determine the most likely …

Multi-Hazard Modelling of Dual Row Retaining Walls
… environmentally friendly design. The dual row retaining wall concept, which features two parallel sheet pile walls with a sand infill between them and tie rods connecting the wall heads, is potentially an efficient and resilient system in the face of both earthquake and tsunami loading. Optimal …

Seismic Behaviour of Retaining Walls with Adjacent Structures
… representing a container crane, a cantilever retaining wall, and liquefiable sand. Two models without a structure behind the retaining wall are considered benchmark tests. Seven dynamic centrifuge tests were conducted to study the effects of various factors on the behaviour of the …

Experimental study of earth pressures on retaining structures
… studies of earth pressures exerted on retaining structures and laboratory studies of the at-rest earth pressure coefficient are summarized. The current methods used to evaluate the earth pressures due to compaction are reviewed. The design features of a new instrumented oedometer …
