Background Data collection for the National Health and Nutrition Examination Survey (NHANES) consists of a household screener, an interview, and a physical examination. The screener primarily determines whether any household members are eligible for the interview and examination. Eligibility is established using preset selection probabilities for the desired demographic subdomains. After an eli...

This paper examines the relationship between household income shocks and child labor. In particular, we investigate the extent to which transitory income shocks lead to increases in child labor and whether household asset holdings mitigate the effects of these shocks. Using data from a household panel survey in Tanzania, we find that both relationships are significant. We investigate mechanisms...

BACKGROUND Rwanda reported significant reductions in malaria burden following scale up of control intervention from 2005 to 2010. This study sought to; measure malaria prevalence, describe spatial malaria clustering and investigate for malaria risk factors among health-centre-presumed malaria cases and their household members in Eastern Rwanda. METHODS A two-stage health centre and household-...

Considering human visual system and characteristics of images, a novel image fusion strategy is presented for panchromatic high resolution image and multispectral image in non-subsampled contourlet transform (NSCT) domain. The NSCT can give an asymptotic optimal representation of edges and contours in image by virtue of its characteristics of good multiresolution, shiftinvariance, and high dire...

This paper presents a comparison of the most frequently used methods for improving the spatial resolution of images. Several methods have been proposed for the merging of high spectral and high spatial resolution data in order to produce multispectral synthetic images having the highest spatial resolution available within the data set, and close to reality. The methods under consideration are B...

Overhead lines are essential components of high voltage power systems worldwide. The performance of this network element is important for a save and reliable transmission of electrical energy. The load capability of a line is related basically to the line design itself and takes centre stage of the economic operation whereas the sag behaviour and the technical condition of the conductor and the...

A useful technique in various applications of remote sensing involves the fusion of panchromatic and multispectral images. Wavelet-based approaches to image fusion generally produce high-quality spectral content in fused images. However, the spatial resolution obtained by most wavelet-based methods is less than that obtained by the intensity-hue-saturation (IHS) method. Recent studies show that...

I-Healthcare can be defined as “intelligent mobile system, medical sensors and android, wireless communications technologies for healthcare.” This emerging concept represents the evolution of i-healthcare systems from traditional desktop “telemedicine” platforms to wireless and mobile configurations. The interest in i-healthcare systems (IHS) originates initially from the need to extend health ...

In this issue of the journal the editors have initiated an historical section. Hansreudi Isler presents a scholarly paper on cluster headache. Apparently, this case report is the earliest description of this disorder which satisfies the new diagnostic criteria of the IHS classification, an admirable example of the ancient and modem. There are many points of value in this work, even a therapeuti...

OBJECTIVE Household food access remains a concern among primarily agricultural households in lower- and middle-income countries. We examined the associations among domains representing livelihood assets (human capital, social capital, natural capital, physical capital and financial capital) and household food access. DESIGN Cross-sectional survey (two questionnaires) on livelihood assets. S...
