We study domain growth in a nonlinear optical system useful to explore different scenarios that might occur in systems which do not relax to ther-modynamic equilibrium. Domains correspond to equivalent states of different circular polarization of light. We describe three dynamical regimes: a coars-ening regime in which dynamical scaling holds with a growth law dictated by curvature effects, a r...

We consider the efficiency of chemical energy extraction from the environment by the growth of a copolymer made of two constituent units in the entropy-driven regime. We show that the thermodynamic nonlinearity associated with the information processing aspect is responsible for a branching of the system properties such as power, speed of growth, entropy production, and efficiency, with varying...

2014 The free growth (at constant temperature) of a columnar hexagonal liquid crystal is described. The chosen material is the hexaoctyloxytriphenylene. Three growth regimes are observed depending upon the value of the supersaturation 0394: a petal-shape regime for 0394 0.2, a dendritic regime for 0.2 0394 0.6 and a dense branching regime for 0394 > 0.6. The first morphological transition ...

this study was conducted to determine the appropriate irrigation interval on the basis of cumulative water evaporation from standard evaporation pan (class a) and to find out the effects of irrigation regimes on growth indices and on qualitative and quantitative yields of sugar beet. the experiment was conducted in 2005 at the lavark agricultural experiment station fields, isfahan university of...

We consider a risk-sensitive optimization of consumption-utility on an infinite time horizon where the one-period investment gain depends underlying economic state whose evolution over is assumed to be described by discrete-time, finite-state, Markov chain. suppose that production function also sequence independent and identically distributed (i.i.d.) random shocks. For sake generality, utility...

In response to our perceptions of the need to clarify the nature of school-based occupational therapy services at the local, state, and federal levels, we have written this article to address three areas. First, we suggest that the terminology used by school-based occupational therapists to describe their work be explained in terms that will allow parents and educators to better understand the ...

This article describes a framework for occupational therapy service provision in early intervention settings and presents pilot data aimed at examining the framework's effectiveness. The Family-Centered Framework for Early Intervention is a synthesis of concepts from the Model of Human Occupation (Kielhofner & Burke, 1980) and from the literature on play. It encompasses a systematic, holistic a...

Bedside shift reports are viewed as an opportunity to reduce errors and important to ensure communication between nurses and communication. Models of bedside report incorporating the patient into the triad have been shown to increase patient engagement and enhance caregiver support and education. Nurse shift reports and nurse handovers are 2 of the most critical processes in patient care that c...
