OBJECTIVE There is uncertainty as to whether asthma has an effect on final height. We investigated using subjective and objective assessments whether untreated asthma is associated with final height, leg length and sitting height to leg length ratio in an area of Chile in which almost no one received asthma treatment. METHODS We collected data on 1232 males and females aged 22-28 years in a s...

In this study we investigated grouping-related F0 patterns in Shanghai Chinese by examining the effect of syllable position in a sandhi domain while controlling for tone, number of syllables in a domain, and focus condition. Results showed that F0 alignment had the most consistent grouping-related patterns, and syllable duration was positively related to F0 movement. Focus and word length both ...

Two assumptions frequently have been made in studies on the growth of individual bacteria. The increase in volume of rod-shaped bacteria has been assumed to consist of an increase only in length; thus, measurements of length have been used to estimate the volume of a cell (A. L. Koch et al., J. Gen. Microbiol. 29:421, 1962; J. F. Collins and M. H. Richmond, J. Gen. Microbiol. 28:15, 1962). Seco...

Retrogressive landslide is caused by the lower rock mass sliding, so that upper part loses support, deformed, and starts to slide. In process of highway construction, incised slope often leads retrogressive landslide, determination damage range great significance for control slope. Taking a in Hunan Province as research object, particle flow discrete element used numerically simulate entire fai...

Entrainment of underlying debris by geophysical flows can significantly increase the flow deposit extent. To study this phenomenon, analog laboratory experiments have been conducted on granular column collapse over an inclined channel with and without an erodible bed made of similar granular material. Results show that for slope angles below a critical value θc, between 10◦ and 16◦, the run out...

Introduction: Slope streaks, commonly dark features in the high albedo, low thermal inertia, dust-rich equatorial regions of Mars, have been observed in images from all orbiting spacecraft since Mariner 9 [1-9] and are thought to fade or brighten over time due to mantling of dust [2,3,8]. Recent studies using images from the High Resolution Imaging Science Experiment (HiRISE) camera [10] have s...

The cycle length (CL) of atrial fibrillation (AF) may have clinical utility, yet reliable CL measurements typically require invasive electrophysiologic study (EPS). We hypothesized that autocorrelation analysis of the ECG accurately reflects intra-atrial CL in AF, and is more robust than spectral analysis from QRS-subtracted ECGs. Methods We studied 39 patients undergoing AF ablation. For ECG l...

The objective of this paper was to explore the bond-slip relationship between carbon fiber-reinforced polymer (CFRP) sheets and concrete under cyclic loading through experimental and analytical approaches. Modified beam tests were performed in order to gain insight into the bond-slip relationship under static and cyclic loading. The test variables are the CFRP-to-concrete width ratio, and the b...

in this study, polyaniline molecule (emeraldine base) is modeled as a molecular wire and the effects of the metal/molecule coupling strength and the molecule length on the current-voltage (i-v) characteristics are numerically investigated. using a tight-binding hamiltonian model, the methods based on non-equilibrium green’s function theory, landauer formalism and newns-anderson model, our calcu...
