In this paper, the kinetic parameters of discarded computer keyboard plastic waste are estimated using thermogravimetric analysis (TGA) with four different non-isothermal kinetic models at a wide range of heating rates 5, 10, 15, 20, 40, 60 and 100 °C/min. The gross calorific value of waste computer keyboard plastic is 38.96 MJ/Kg. FT-IR analysis c...
This article is devoted to the development of a conceptual model of the structure of the geoinformation system (GIS) for the administrative and economic management of regional airports, taking into account the requirements of world and national experience, international and national standards, modern technologies of geospatial data collection. The ...
The value of a property comprises the value of both the building and the land. Numerous studies have reported a nonlinear relationship between house age and housing prices, which may result from mispricing the value of the land. The paper establishes a theoretical model to evaluate the optimal time for land redevelopment and the land value after re...
This work reports the thermo-catalytic conversion of medical plastic wastes to fuel oil using the detergent grade Zeolite A as the catalyst. The effect of catalyst on the pyrolysis is ascertained from the kinetic data obtained from thermogravimetric analysis assuming it to be a first-order reaction. A significant reduction in activation energy of t...
Faced with a complex and volatile environment, improving the resilience of organizations to resist various risks, enhancing the viability of enterprises, and ultimately achieving sustainable development capabilities has become a top priority for business managers. This study first explores the relationship between employee psychological ownership, ...
One of the most important issues is to achieve maximum production of energy from a particular energy source, which ensures the complete protection of the environment. The current paper as the first application of flexible and powerful semi-disposability approach, performs an empirical technical and environmental efficiency analysis for 39 natural g...
To be digitally responsible, one should be aware of the current issues in the digital world; therefore, raising awareness on digital responsibility and data privacy is important in the public and private sectors. This study aimed to raise awareness on digital responsibility and help students understand the importance of utilizing the design thinkin...
An analysis of urbanization’s effects on energy efficiency (EE) is presented in this paper. We develop an input-oriented data envelopment analysis method to estimate EE in the presence of non-convex metafrontier, and examine how urbanization affects China’s EE using data from 251 cities for the period 2003 to 2016. The findings indicate that demogr...
With the rapid energy consumption increase in China’s non-ferrous metal industry (NMI), there are inequalities in energy-related CO2 emissions among the sub-sectors. In this paper, a meta-frontier decomposition analysis was proposed for decomposing inter-structural low-carbon economic development inequalities among 29 sub-sectors in China’s NMI fro...
This article aims to identify and verify the relationship between entrepreneurial orientation and innovation of internationalised firms from Poland as a former emerging market. The article assesses this relationship in terms of the internationalisation scope. We adopted a quantitative research design and conducted a CATI survey on a sample of 355 f...
