We use longitudinal data from children growing up in four developing countries (Peru, India, Vietnam, Ethiopia) to study the relationship between height at the age of 7-8 and a set of psychosocial competencies measured at the age of 11-12 that are known to be correlated with earnings during adulthood: self-efficacy, self-esteem and aspirations. Results show that a one standard deviation increas...

This work aims to establish a relationship between volume and biomass with interferometric and radiometric SAR (Synthetic Aperture Radar) response from planted Eucalyptus saligna forest stands, using multi-variable regression techniques. X and P band SAR images from the airborne OrbiSAR-1 sensor, were acquired at the study area in the southeast region of Brazil. The interferometric height (Hint...

The scaling relationship between height and diameter is important for understanding the dynamic patterns of tree growth and estimating the accrual of tree biomass. Metabolic ecology predicts that tree growth follows a universal scaling invariant relative to the height-diameter relationship (i.e., no variation based on taxonomy or resource availability). Comparing field data for different tree s...

Computing object distance using image processing is an important research area in the field of computer vision and robot navigation applications. In this paper we have proposed a new method to compute the distance of an object using a single image. According to our observation there exists a relationship between the physical distance of an object and its pixel height. We exploit this relationsh...

This paper presents a new method for optimizing the hub height of a wind turbine. In general, wind turbine energy production increases with the hub height, but so does the cost. Therefore, we must optimize the hub height. Here, we calculated the annual energy production using a wind probability function. This is a function of the hub height and the roughness, which is a surface characteristic. ...

BACKGROUND Many conditions affect renal size. To evaluate abnormalities in renal size, knowledge of standardised values for normal renal dimensions is essential as it shows variability in the values of normal renal size depending on body size, age and ethnicity. Ultrasound, being an easily available, noninvasive, safe and less expensive modality, is widely used for evaluation of renal dimension...

Key Points Summary We report how blood pressure, cardiac output and vascular resistance are related to height, weight, body surface area (BSA), and body mass index (BMI) in healthy young adults at supine rest and standing.Much inter-subject variability in young adult's blood pressure, currently attributed to health status, may actually result from inter-individual body size differences.Each car...

BACKGROUND Mechanisms underlying the inverse relationship between height and cardiovascular mortality are unknown but could relate to central hemodynamics. We sought to determine the relation of height to central and peripheral hemodynamics, as well as clinical characteristics. METHODS The study population was comprised of 1,152 randomly selected community-dwelling adults (aged 67.7 ± 12.3 ye...

Why a Sex Difference in Age-Adjusted Relationship Between Height and Stroke Mortality? To the Editor: We read with interest the study by Hozawa et al,1 who concluded that height is inversely related to stroke mortality and that the relationship is statistically significant among women but not men when adjusted for age. The authors put forward several possible confounding factors including age e...
