This paper argues that our sociological explanations of the historical advent of gender stratification in the Occident has given too much attention to techno-economic causes and too little attention to religious, cultural and ideological causes. Evidence for this claim is taken from archeology, mythology and anthropology for the relevant historical period (4500 and 3000 BC) in Eurasia. I assert...

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...

The adoption of private 5G networks or Non-Public Networks (NPN) by industry verticals is igniting a digital transformation across various sectors and also leading to 4.0. This impetus comes from the integration wireless with capabilities. Currently, range innovative applications use cases are emerging resulting in improved enterprise performance solutions. potential boost revenue, stimulate co...

In this study, different battery types to be used in the conversion of a small and light (600-1000 kg) internal combustion engine vehicle into an electric were analyzed. The study was conducted ensure that is suitable for urban use has range approximately 100 km. Each technology capacity evaluated 15 kWh. While performing techno-economic analysis types, it taken account they provide necessary e...

The direct dehydrogenation of butane (BDH) is emerging as an attractive on-purpose technology for the production 1,3-butadine. However, its product yield hindered by high rate carbon deposition associated to temperature required highly endothermic reaction. In this work, we evaluated use H2-selective membrane reactor, increase process at milder operating conditions. novel proposed reactor (MR)-...
