OBJECTIVES/HYPOTHESIS Determine whether quantitative geometric measures and a computational fluid dynamic (CFD) model derived from medical imaging of children with subglottic stenosis (SGS) can be effective diagnostic and treatment planning tools. STUDY DESIGN Retrospective chart and imaging review in a tertiary care hospital. METHODS Computed tomography scans (n = 17) of children with SGS ...

one of the possible ways to ensure future food needs of an increasing world population involves the better water use through the development of crop varieties which need less water and are more tolerant to drought. in order to study the response of twenty landraces of bread wheat to drought stress, an experiment was conducted in a randomized complete block design with three replications under t...
section{introduction} the concept of {sl cartan geometry} appeared at the beginning of the twentieth century, when {e}lie cartan was working on the so-called {sl equivalence problem}, the aim of which is to determine whether two given geometric structures can be mapped bijectively onto each other by some diffeomorphism. this problem can be considered in many different contexts, such as ...
The divergence through infinity of certain eigenvalues of a linearized differentialalgebraic equation (DAE) may result in a stability change along an equilibrium branch. This behavior cannot be exhibited by explicit ODEs, and its analysis in index one contexts has been so far unduly restricted to semiexplicit systems. By means of a geometric reduction framework we extend the characterization of...
the adverse effect of climate change on agriculture has increased the importance of weather index insurance, particularly in developing countries. by using several econometric models, this study estimated the price and evaluated its effectiveness in rainfall index insurance for rice and wheat in nepal. crop yields associated with seasonal rainfall in three crop reporting districts were applied ...
This experiment was conducted in the Research Farm of the Faculty of Agricultural Sciences, University of Guilan in 2010 as an RCBD based split plot experiment with three replications. In this experiment five different amounts of soil moisture (Irrigation after depletion of 45, 55, 65, 75 and 85% of field capacity moisture) and two soybean cultivars (Gorgan-3 and Williams) was considered as mai...
Many techniques have been developed to quantify different conceptualizations of self-interaction and patterns within spatial data. We propose a new metric related algorithm that describes the geometric disorder geographic point sets, “Index Disorder” (IoD). The IoD was applied synthetic natural datasets shown be able differentiate between areas high (randomly placed points) low (e.g., curviline...
the effect of late planting heat stress on yield and yield components was studied in 11 barley lines from icarda and one cultivar from iran (izeh) during two years (2005-2007) in gachsaran dry-land agricultural research station. each line was planted in a 6-rowed plot at two dates: normal planting (middle of november) and late planting (end of december) with three replications using a randomize...
