Abstract. The main idea of the report is that the yield surface can be presented as thick, "foamed surface" with dimensionality exceeding two. By other words, perhaps, the yield surface is fractal, i.e. it belongs to the geometric objects with fractional dimensionality. Apparently, fractal structure of the yield surface is determined by the fractal structure of natural materials. Besides, the “...

BACKGROUND Production of chemicals from engineered organisms in a batch culture involves an inherent trade-off between productivity, yield, and titer. Existing strategies for strain design typically focus on designing mutations that achieve the highest yield possible while maintaining growth viability. While these methods are computationally tractable, an optimum productivity could be achieved ...

given the scarcity of water resources using modern methods of irrigation in agriculture will be inevitable. today, process improvement, development and use of drip irrigation practices as one of the most advanced methods of irrigation in agriculture is increasing. so this study was conducted to determine the impacts of irrigation interval and drip irrigation method and their interactions on yie...

Identifying the composition of the catalytically active state of metal catalysts under dynamic operating conditions is of particular importance for oxidation catalysis. We report here new insights into the chemical identity of different catalytically active states formed on a Ru(0001) catalyst during the CO oxidation at different reaction temperatures. The changes in the surface composition of ...

The dynamic characteristics of a tip oscillating in the nc-AFM mode in close vicinity to a Cu(100)-surface are investigated by means of phase variation experiments in the constant amplitude mode. The change of the quality factor upon approaching the surface deduced from both frequency shift and excitation versus phase curves yield to consistent values. The optimum phase is found to be independe...

Real-time active 3D range cameras based on time-of-flight technology using the Photonic Mixer Device (PMD) can be considered as a complementary technique for stereo-vision based depth estimation. Since those systems directly yield 3D measurements, they can also be used for initializing vision based approaches, especially in highly dynamic environments. Fusion of PMD depth images with passive in...
