AIMS AND OBJECTIVES To explore how nurse researchers in clinical positions experience the presence of a nursing research culture in clinical practice. BACKGROUND Higher demands in the hospitals for increasing the quality of patient care engender a higher demand for the skills of health professionals and evidence-based practice. However, the utilisation of nursing research in clinical practice...

Hydrocarbon wells drilled vertically through longwall coal pillars are vulnerable to severe deformation and potential failure as a result of underground coal mining. The lithology of the host rocks play a critical role in well stability. In this study, a two dimensional finite element method is employed to investigate the horizontal shear offset, vertical delamination, and compression at the we...

Manipulated variable moves are computed to maximize the information contained in experimental data collected from sheet and film processes. The experimental design procedure minimizes the confidence ellipsoid of the critical model parameters over the manipulated variables subject to their physical constraints. For a simulated blown film process, the model is 1 order of magnitude more accurate t...

A comprehensive investigation was carried out to minimize the cost price of the rock fragmentation process including: drilling, blasting, secondary blasting and separating the large boulders (oversize rocks) while loading, until the optimized fragmentation, powder factor and ratio of burden (B) to blasthole diameter (?h) were achieved by doing several stages of drilling and blasting practically...

The paper uses mathematical modeling to calculate loads on interchamber pillars under incomplete undermined conditions by using the room and pillar system at great depths retaining rigid barrier pillars. approaches are based method of fictitious pillars, as well forming a rock pressure arch in incompletely area. unloading effect is shown, distribution vertical obtained, height calculated.

One of the most striking aspects of the cellular pattern within the sensory epithelium of the mammalian cochlea is the presence of two rows of pillar cells in the region between the single row of inner hair cells and the first row of outer hair cells. The factors that regulate pillar cell development have not been determined; however, previous results suggested a key role for fibroblast growth ...
