The technology gap between developing and advanced countries has been increasing during the last few decades. In the process of technology development human capital plays a critical role as an absorption capacity for new technologies in developing countries. The cross-country regression shows that human capital interacts with inows of foreign technology embodied in machinery imports as well as...

background: optical mammography is a new diagnostic method that uses near-infrared for detection of functional abnormalities and shows tissue activities by measuring absorption and scattering of near-infrared light. this study aims to evaluate the safety and effectiveness of this technology. methods: cochrane library (issue 10, 2012) and medline (nov 2012) were searched using free text and mesh...

during the past decade, the world economic forum has published its annual reports in which the global competitiveness index is included. this paper aims to investigate the key factors for achieving an innovation-driven economy. in this paper, we used partial canonical correlation analysis (pcca) to examine the relationships between key pillars in “efficiency enhancers” and “business sophisticat...

phytoremediation is an eco-friendly method for removal of pollutants, which can be relied upon as a sustainable technology, if implemented under optimum conditions of plant growth. the effectiveness of water hyacinth, a topical weed, for the removal of zinc (zn) and chromium (cr) ions from aqueous solutions has been presented in this article. the potential of this plant in removing metals by ph...

Nanoparticles and molecular chromophores with strong optical absorption in the near-infrared spectral range can be used as contrast agents for optoacoustic (photoacoustic) imaging, thereby significantly enhancing sensitivity and enabling new applications of this novel and rapidly growing biomedical imaging technology.

The accuracy of models for primary production and light propagation depends on correct assignment of absorption to photosynthetic pigments. The phytoplankton absorption coefficient is comprised of two components: photosynthetic and photoprotective absorption coefficients. A method based on the fluorescent excitation of chlorophyll a is used to quantify the photosynthetic absorption coefficient ...

nowadays, the use of innovative nano-technology in the food industry quality control has significantly increased and it is widely employed in numerous fields such as diagnosis of microbial toxin of foods using nano-biosensors, increasing food shelf-life with the help of nano-clay and nano-silver packaging, as well as changing some of the unpleasant organoleptic properties such as taste, color, ...
