It is investigated UFG structure formation in CP Ti bulks processed by SPD (cold Twist Extrusion (TE), true strain e∼5.1, with the following Cold Rolling (CR), true strain e∼0.7). Evolution of microstructure and tensile mechanical properties in the CP Ti were investigated under room temperature. After the TE, in transversal section it is formed structure fragments with size less 1 μm. Strength inc

This paper presents annual estimates of total and per-capita GDP at 1910 prices for the regions of Imperial Austria from the origin of the Dual Monarchy (1867) to the eve of WWI (1913). The time paths of regional GDP are estimated from the yield of the tax on the transfer of real and financial property which is itself very highly correlated with the Schulze (2007) estimates of regional GDP for cen

We consider a real-time system of multiple tasks, each task having a plant to control. The overall quadratic control cost is to be optimized. We exploit the periodicity of the task response time, which corresponds to a periodic delay pattern in the feedback control loop. Perturbed periods are used as a tool to find a finite hyperperiod. We present an analytical procedure to design a periodic linea

The aim of the document is to identify and discuss a number of growth paths that might be explored to promote innovationdriven development in Sub-Saharan Africa. The document adopts a broad perspective of innovation, examining framework conditions, fundamental prerequisites, drivers and focal areas for innovation. The document addresses a spectrum of issues andtopics ranging from regional and glob

Optothermal spectrometry measures the thermal energy produced as a result of absorption by molecules at a given modulation frequency and wavelength. Depending on the modulation frequency used, analysis can be performed in very thin layers (50—150 micrometers). A major advantage of optothermal spectrometry is that it is not very sensitive to light scattering. Haemoglobin in whole blood was measured

During the last 30 years or more, the migration industry has been conceptualized in reference to activities –usually informal or illegal– of certain intermediaries who profit by providing services to migrants.The position taken in this article is that the increasing commercialization of international migration makes it necessary to conceptualize the migration industry more broadly and include both

This paper analyzes various innovation strategies of firms. Using five waves of the Community Innovation Survey in Sweden, we have traced the innovative behavior of firms over a 10-year period, i.e. between 2002 and 2012. We distinguish between sixteen innovation strategies, which compose of Schumpeterian four types of innovations (process, product, marketing, and organizational) plus various comb

Pneumococci isolated from the ear exudate in 245 children under 10 years of age afflicted with acute otitis media were typed. Types 3, 6, 14, 18, 19 and 23 were found in 80% of the cases. In the remaining cases, 15 other types were found. Five strains were not typable with the antisera used. Types 14 and 23 were found twice as often in the age group 0-3 years as in the higher age groups, whereas t
