There has been much recent discussion ahout the ultimate sources of macroeconomic variability. A number ofauthors attribute most of this variability to only B few sowces, sometimes only one. Although there may be only B few important sources, this is fsr from obvious, since economies seem compliested. The purpose of this paper is to provide qusntitstive estimates of various sowces of vsriabilit...

In this review, we present an overview of the technologies in colorimetric biosensors based on DNA-nanoparticle conjugates. Two types of DNA-nanoparticles aggregation assays are summarized. One of the methods relies on cross-linking of the gold nanoparticle (GNP) by hybridization. The crosslinking system was used not only to detect target DNA sequences, but also to detect metal ions or small mo...

objective(s): abdominal adhesions are one of the most important problems, occurring after intra-abdominal surgery in more than 90% of cases. this condition is the leading cause of bowel obstruction, infertility, and abdominal/pelvic pain. gold nanoparticles (gnps) have been shown to be non-toxic and exhibit anti-inflammatory, anti-angiogenic and antioxidant activities. the purpose of this study...

hIn the first section of the study we gave some general informations on the Information Society; for example we have figures showing the contribution of information and communication technologies to GNP and to GNP growth in US; or proving that in “ICT intensive” companies, there is anhigher productivity growth . We mentioned also the growing impact of information society on jobs; it’s quoted an...

This study aims to identify the relationship between population density, inflation, and unemployment rates on human development index, GNP, export-import, urbanization in developed developing countries category using Fix Effect Seemingly Unrelated Regression (FE SUR) with a dummy variable as slope component. research necessitates of model, specifically Panel (Panel model component, due dynamic ...

Abstract Directional strain sensing is essential for advanced sensor applications in the field of human‐machine interfaces and healthcare. Here, angle dependent anisotropic sensitivity caused by charge carriers percolating through cross‐linked gold nanoparticle (GNP) networks studied these versatile materials are used fabrication wearable triaxial pulse gesture sensors. More specifically, respo...

Commentary The economic burden of global blindness: a price too high! The World Health Organisation defines blindness as a best corrected visual acuity of less than 3/60.1 Using this definition it is estimated that there are currently 37 9 million blind people (1-4 million children 0-15 years of age, and 36-5 million adults 15 years of age or greater) worldwide.2 Of this figure roughly 75% of a...
