Processes that use moving point heat sources to temporarily create localized melt pools (metal additive manufacture and fusion welding) have a flow phenomenon due the surface tension gradient. Surface of liquid metal reduces with temperature this, coupled high gradients associated sources, creates Marangoni convection in melt. The tends reduce change pool geometry (increases width but depth). C...

Many studies have noted significant differences among human electroencephalograph (EEG) results when participants or patients are exposed to different stimuli, undertaking different tasks, or being affected by conditions such as epilepsy or Alzheimer's disease. Such studies often use only one or two measures of complexity and do not regularly justify their choice of measure beyond the fact that...

This paper presents a modified digital image watermarking method based on nonnegative matrix factorization. Firstly, host image is factorized to the product of three nonnegative matrices. Then, the centric matrix is transferred to discrete cosine transform domain. Watermark is embedded in low frequency band of this matrix and next, the reverse of the transform is computed. Finally, watermarked ...

based on the randic suggestion of the resolution of a structure into shape, size, and function an index representing structure-catabolic fate relationships of amino acids is constructed. the index obtained by multiplying three factors; (nb2 + nr), nc and m; representing shape, size and function respectively, where nb2 = number of double bonds, nr = number of rings, nc = number of carbon atoms, ...

OBJECTIVE To explain patterns of fruit and vegetable consumption in nine former Soviet Union countries by exploring the influence of a range of individual- and community-level determinants. DESIGN Cross-sectional nationally representative surveys and area profiles were undertaken in 2010 in nine countries of the former Soviet Union as part of the Health in Times of Transition (HITT) study. In...

With rising climate change concerns and increasing energy demand, many of the developed countries are pursuing sustainable low carbon economic development plans. The dramatic use fossil-fuel in economy increases level dioxide emissions. Carbon (CO2) is dominant greenhouse gas that intensifies global warming phenomena as a challenge over last two decades. As nations around world taking immediate...

BACKGROUND The data comparing daily versus intermittent iron supplementation during pregnancy remain controversial. This study was undertaken to compare the efficacy of daily versus two different intermittent iron supplementation regimes on hematologic markers and birth outcomes in nonanemic pregnant women. METHODS Two hundred and ten women with singleton pregnancies, no known disease, and he...

Epithelia are compact tissues comprising juxtaposed cells that function as mechanical and chemical barriers between the body and the environment. This barrier relies, in part, on adhesive contacts within adherens junctions, which are formed and stabilized by E-cadherin and catenin proteins linked to the actomyosin cytoskeleton. During development and throughout adult life, epithelia are continu...
