Tectonic geomorphology has been evidenced as an essential tool to define and measure recent tectonic deformation. The Nandakini River originates from Nanda Ghunti glacier at 6886 m in Lesser Himalaya. It covers about ~551 km2 basin area, with a fourth-order stream. It confluences with the Alaknanda River near Nand Prayag (at elevation 852 m), Chamoli district of Uttarakhand. The drainage pattern is predominantly dendritic in the study area. The morphotectonic indices are measured to know the tectonic activity of th [...]

Value co-creation in the digital innovation ecosystem is of great practical significance for promoting enterprise advantages and high-quality economic development. Digitalization reshapes the logic of value co-creation. Innovation activities are no longer focused only on the internal enterprise but also occur in the ecosystem of interaction and sharing with other heterogeneous and diverse subjects. How can value co-creation be achieved between the digital innovation ecosystems and how can they be coupled between th [...]

The review article discusses the application of biogeochemical technologies aimed at restoring biogeochemical cycles in agroecosystems, primarily in the microbial link regulating CO2 flows. The factors of management this microbial link when applying mineral and organic fertilizers are shown. The processes of mineralization of soil organic matter and methods of controlling soil's conjugate carbon- and nitrogen-mineralizing ability are considered. The changes in the productivity of agricultural ecosystems under condi [...]

Industrial and urban development are contributing to an increase in global environmental degradation. Therefore, the release of heavy metals from mining-related operations into surface water is harmful to human health. But as anthropogenic influences on the environment grow, surface water characteristics are also alter, impacting aquatic creatures. In order to analyze the acceptability of the surface water in the gold mining area for drinking and irrigation uses, different quality water assessment methodologies wer [...]

Following the establishment of the United Nations’ Sustainable Development Goals, sustainability has been given increasing attention in the agenda of the built environment. Sustainability embraces three key elements, i.e., environment, economy and society. However, the social dimension receives the least attention and is largely overlooked compared to the environmental and economic sustainability. To bridge the gap, this paper will examine the various dimensions of social sustainability involved in the built enviro [...]

The Contingent Valuation (CV) Method, like other stated preference techniques, seeks to measure economic preferences for public goods. Throughout the development and application of this non-market procedure, the accuracy of the measured preferences has been front-and-centre among practitioners and potential users. The most important issue of debate has been the extent to which the method can reliably measure economic preferences. In this article, a new methodology is described that enables multiple indicators of la [...]

Water bodies have been severely degraded in recent years due to the indiscriminate use of agro-allied chemicals. The study assesses the agro-allied chemical pollution on the surface water quality in River Lamurde and Mayo Gwoi. Water samples were collected from twenty-one (21) sample locations along the River Lamurde and Mayo-Gwoi to determine the seasonal variation during the wet and dry seasons through field determination of water quality and laboratory-based analysis at Taraba State Rural Water Supply and Sanita [...]

This paper pictures several risk-taking strategies of young high-tech firms in bringing energy inventions to market and ways urban policy (municipalities) may provide supporting facilities and help accelerate the energy transition. Derived from a longitudinal study of 100 firms in northwest Europe, two findings contribute to practice. Firstly, a share of almost 40 percent of university spin-off firms fails in the market introduction; if the market introduction is reached, 30 percent is relatively late. This develop [...]

Iraq’s lakes and rivers are currently exposed to drought because of climatic and political conditions. This study uses satellite images and geographic information systems to display the water depletion and the change in the surface water area of Hamrin Lake. Sentinel-2 imagery of 2018 and 2022 was used to analyze the surface water area changes and water depletion. A comparison was made by studying the changes that happened between 2018 and 2022 respectively. Moreover, a supervised classification technique was imple [...]

This work aimed at evaluating all products from the low-temperature pyrolysis (350°C) of some industrial wastes, cotton stems and seeds (CSS), grape husks and curls (GRH), undigested sewage sludge (USS) and their blends in a fixed bed system and suggesting their possible applications. Solid and liquid products, biochars, and bio-oils were analyzed using various techniques by physicochemical, mineralogical, and chemical analyses. Gases were qualitatively and quantitatively analyzed using a thermogravimetric-mass spe [...]
