Cucurbiturilas

This review article describes the properties and the main applications of the glicol[n]urils. These compounds are cavitands made of n glycolurilic units arranged in circles, giving rise to extremely symmetric toroidal molecules. The cucurbit[n]urils create this way variable-sized hydrophobic cavities and the glycolurilic carbonyles delimit two portals on these cavities, slightly narrower than their internal radii. Their structure, physical and chemical properties favor the formation of inclusion compounds, and turn them into important building blocks for supramolecular chemistry and nanotechnology.

Giving voice to lifelong learning in professional nursing practice

The purpose of this phenomenological study was to uncover the meaning of lifelong learning to nurses in an Academic Health Care setting. Six female pediatric nurses were interviewed and audiotaped in response to 2 main questions of interpretation and engagement in lifelong learning with respect to their nursing practice. Four additional probing questions elicited responses of further qualities and characteristics of the meaning of lifelong learning. The emergent themes uncovered the characteristics and nature of the journey of lifelong learning. The themes evolved into parallel characteristics developing into the concepts of personal empowerment and occupational authorship. The personal empowerment concept involved processes whereby the participants overcame or removed barriers to engage in personal lifelong learning. Participants utilized personal power and internal motivators to sustain their engagement in lifelong learning. The occupational authorship concept involved participants controlling their exploration into lifelong learning through collaboration and recognition of occupational demands to be met as a professional. The remaining themes revealed a seasoning journey. This journey entailed a process of mastery through the themes of engagement discord, discovery pilgrimage, transforming, and maturation. The engagement in this journey resulted in their lifelong learning to becoming more intuitive and a part oftheir being. The overall theme uncovered from the journeys was one of a vocation described as a call to thinking critically of nursing practice. The participants responded to lifelong learning as a call to be a good nurse by using critical thinking through reflection, transformative and constructionist learning processes. This study gave voice to the meaning of lifelong learning in their nursing practice as interpreted by -ao the nurse participants.

Two rows : assimilative transformations impacting Six Nations' educational and communal circles

This study examines the current educational and community realities faced by a large First Nations community in Canada. First, the research explores the voices of youth and parents to determine the current issues and trends of an Aboriginal community. Second, the work discusses the transformation of Six Nations youth and parents and its impacts on student educational and community life. Third, I relate my personal experiences as a First Nation student, parent, and community agency representative.

New Simulated Corrugated Scaltering Surface Giving Widebandcharacter I Sti Cs

Simultaneous elimination of specular reflection and backscattered power from a plane metallic surface by simulated corrugated surfaces of constant period and variable strip width for TM polarisation is reported. This new configuration offers almost a ten-fold frequency bandwidth compared with a regularly spaced strip grating of the same size.

Matching Interest Points Using Projective Invariant Concentric Circles

We present a new method to perform reliable matching between different images. This method exploits a projective invariant property between concentric circles and the corresponding projected ellipses to find complete region correspondences centered on interest points. The method matches interest points allowing for a full perspective transformation and exploiting all the available luminance information in the regions. Experiments have been conducted on many different data sets to compare our approach to SIFT local descriptors. The results show the new method offers increased robustness to partial visibility, object rotation in depth, and viewpoint angle change.
