Background: The nursing students should acquire practical and theoretical competence required for the patients' care during their 4 years of education. This involves proper use of time. The purpose of this study was to investigate how nursing students manage their time despite the academic difficulties and obstacles. Methods: This qualitative study was carried out through grounded theory met...

Plant cells in tissues experience mechanical stress not only as a result of high turgor, but also through interaction with their neighbors. Cells can expand at different rates and in different directions from neighbors with which they share a cell wall. This in connection with specific tissue shapes and properties of the cell wall material can lead to intricate stress patterns throughout the ti...

This paper investigates the induced stresses in circular single deck roofs floating on seismically excited storage tanks. Equations of motion are derived using variational principle. Response of deck floating roofs is evaluated for two different classes of ground motions; near-source and long-period far-field records. Besides time histories and frequency contents for a specific tank, peak value...

Spatial patterning of cell behaviors establishes the regional differences within tissues that collectively develop branched organs into their characteristic treelike shapes. Here we show that the pattern of branching morphogenesis of three-dimensional (3D) engineered epithelial tissues is controlled in part by gradients of endogenous mechanical stress. We used microfabrication to build model ma...

Introduction: Modeling of the surface stresses on Europa has been performed to date, considering tidal, nonsynchronous, and polar wander sources of stress [3-6]. The results of such models can be used to match lineament orientation with the candidate stress patterns. Moreover, stratigraphic analysis can be used in combination with stress modeling to infer the evolution of Europa’s surface back ...

background: the aim of this study was to compare the skeletal and dental changes of a toothborne (hyrax) and a bone-borne (smile distractor) expansion devices using three-dimensional model of a human skull. materials and methods: a finite element model of human skull was generated using data from 3-d ct scans of an 11-year-old female child. then a hyrax expander (tooth-borne appliance) and smil...

This paper presents findings from two eye-tracking studies designed to investigate the role of metrical prosody in silent reading. In Experiment 1, participants read stress-alternating noun-verb or noun-adjective homographs (e.g. PREsent, preSENT) embedded in limericks, such that the lexical stress of the homograph, as determined by context, either matched or mismatched the metrical pattern of ...
