background:  iodine deficiency disorder (idd) creates major public health problems in india, including gujarat. the bharuch district is a known iodine deficiency endemic area. this study was conducted to estimate the prevalence of  goiter in primary school children; to determine the median urinary iodine concentration; to assess the level of  iodine in salt samples at the household and retail s...

Childhood migraine may present in a similar way to migraine in adults but non-headache and neurological symptoms (aura) may be more prominent than the headache. No formal classification of headaches specific to children exists. The International Classification of Headache Disorders (ICHD) from the International Headache Society (IHS) defines migraine and recognises the childhood variants in its...

In this paper, a framework for diffusion of color images is presented. The method is based on the theory of thermodynamics of irreversible transformations, which provides a suitable basis for designing correlations between the different color channels. More precisely, we derive an equation for color evolution, which comprises a purely spatial diffusive term and a nonlinear term that depends on ...

China is experiencing a drastic loss of arable land as a result of the continuing process of rapid urbanization. This loss could have an adverse impact not only on China’s sustainable development but also on the world food market. To provide a robust and economical tool for evaluating the impact of this process, we developed an IHS (Intensity, Hue, Saturation)-based approach for detecting the c...

Uganda suffers from a high rate of child mortality which has improved little if at all in the last twenty years. The paper uses data from the 1992 Integrated Household Survey to model the determinants of child mortality and malnutrition. Parental beliefs about health have a strong and very highly significant influence on child mortality. Education and income also play a role, partly coming thro...

The IHS sharpening technique is one of the most commonly used techniques for sharpening. Different transformations have been developed to transfer a color image from the RGB space to the IHS space. Through literature, it appears that, various scientists proposed alternative IHS transformations and many papers have reported good results whereas others show bad ones as will as not those obtained ...

Secondary sources of information indicate that the proportion of child deaths due to injuries is increasing in Nepal. This study aimed to describe the epidemiology of unintentional injuries in children, explore risk factors and estimate the burden faced by families and the community in the Makwanpur district. We conducted a household survey in Makwanpur, covering 3441 households. Injuries that ...

This paper mainly addresses the problem of multipolar Synthetic Aperture Radar (SAR) and colorful optical images fusion by regarding them as multichannel images. Based on traditional wavelet-based and model-based fusion algorithms, the paper proposes a multi-channel image fusion algorithm based on a multi-multiturbo iterative method. Multi-multiframe is proposed to represent the original image ...

On board of Quickbird satellite two types of sensors are present: panchromatic and multispectral. The first acquires earth images within spectral range 0.405 μm – 1.053 μm; the second acquires simultaneously four images of the same scene, each of them within shorter range of spectrum (Blue, Green, Red, Near-Infrared). Panchromatic images present geometric resolution 0.60 m while multispectral o...
