One of the greatest contributions of Science and Technology Studies (STS), in the last 30 years, has been to show that the contours of science/technology and society are inextricably interwoven (Bloor [1976] 1991, Latour & Woolgar [1979] 1986; Knorr Cetina 1981; Shapin & Schaffer 1985; Latour 1987; Haraway 1991). These studies have highlighted that techno-scientific developments are path-depend...

In this paper, the authors propose a techno-economic comparative analysis between different lighting solutions, using, respectively, floodlight with metal halide lamps, luminaires with fluorescent lamps and LED floodlights. The comparison is aimed to identify general criteria for assessing the techno-economic sustainability of the use of LED lighting for indoor sports facilities, since this sol...

One of the basic problem of the project process is to create a structure of communication systems with optimal techno-economic factors. In this paper we show optimization capital costs methods of creating the network infrastructure with reference to the defined parameters which describe a designing topology.

The well-known sorting processes like density separation, separation in magnetic or electric fields and flotation, are not suitable to apply successfully within a particle-size range smaller than 10 m. Due to insufficient selectivity of above mentioned enrichment processes the concentrate recovery at this particle size range is extremely poor, which influences accordingly the techno-economic ef...

BACKGROUND Microalgal triglycerides (TAGs) hold great promise as sustainable feedstock for commodity industries. However, to determine research priorities and support business decisions, solid techno-economic studies are essential. Here, we present a techno-economic analysis of two-step TAG production (growth reactors are operated in continuous mode such that multiple batch-operated stress reac...

This work addresses the economic and environmental performance of integrated biorefineries based on sugarcane juice and residues. Four multiproduct scenarios were considered; two from sugar mills and the others from ethanol distilleries. They are integrated biorefineries producing first (1G) and second (2G) generation ethanol, sugar, molasses (for animal feed) and electricity in the context of ...

Techno - economic data on 44 tree species used as crude drugs in various ayurvedic preparations are provided. To maintain quality and reasonable trice, it is suggested that the procurement and sale of crude / raw drugs should be carried out by government agency.

The objective of this work is to design control strategies which optimize composition of production, technology stock and their rates in a nonlinear model of economic growth. The optimal control problem of R&D investment is formulated for a discounted utility function which correlates the amount of sales and production diversity. The maximum principle of Pontryagin is applied for designing opti...
