Summary The ecological crisis is a result of modern industrial development and its negative impacts which are not conducive to the co-existence of essential diversities in the ecosystem. One of the major trends in present day industry is to move towards computer-based automation. This article discusses the compatibility of this trend towards automation with sustainable development which is regarded as the only viable choice to overcome the ecological crisis. After discussing the present day concepts of sustainable development, automation and the economic impact of automation on society, this paper argues that computer-based automation in industry is not conducive to sustainable development. It is also argued that the spread of automation will decrease the capability of mankind as a whole to implement environmentally sustainable programmes. Finally, the man-nature relationship which is the philosophical basis of the industrial paradigm is discussed. As pointed out by some comparative philosophers, the basic concept of human superiority and separation from nature has to change in order to have a harmonious integrity of life forms as complementary realities in this phenomenal existence.Satyabrata Pradhan is a Post Doctoral Research Fellow of the Department of Mechanical Engineering at the University of British 相似文献

Sources of organic matter (OM) in lower Narmada and Tapi river-estuaries were examined using organic carbon to nitrogen ratio (Corg/N), stable carbon isotope ratio (δ13Corg) and lignin phenol biomarkers. The signature of lower Corg (av. 0.50%) and higher δ13Corg (av. –20.3‰) in Narmada and, higher Corg (av. 0.85%) and lower δ13Corg (av. –22.8‰) in Tapi highlight the difference in OM characteristics of both systems, nevertheless they flow adjacent to each other. The OM in Tapi was predominated by fresh plant tissues, as indicated by higher Λ8?=?1.2–3.2?mg/100?mg Corg, lower Ad/Alv?=?0.22–0.46 and lower LPVI?=?17–23. The plant OM present in the sediments of Narmada was previously degraded and mixed with soil. The OM contribution from algae was restricted to estuarine stations in both the rivers, which was ~50% in Narmada and ~35% in Tapi. The contribution of OM from fresh vascular plant was higher (20% to 63%) in Tapi than Narmada (2% to 35%). This study illustrated the benefits of using lignin phenols along with Corg/N and δ13Corg to identify the potential OM sources in two large river–estuary systems of India, which highlighted the complex interaction of natural and anthropogenic processes acted on the terrestrial OM compositions. 相似文献

In this study, the authors explore three persistence approaches in streamflow forecasting motivated by the need for forecasting model skill evaluation. The authors use streamflow observations with 15 min resolution from the year 2008 to 2017 at 140 United States Geological Survey streamflow gauges monitoring the streams and rivers over the State of Iowa. The spatial scale of the basins ranges from about 7 to 37,000 km2. The study explores three approaches: simple persistence, gradient persistence, and anomaly persistence. The study shows that persistence forecasts skill has strong dependence on basin scales and weaker but non‐negligible dependence on geometric properties of the river network for a given basin. Among the three approaches explored, anomaly persistence shows highest skill especially for small basins, under about 500 km2. The anomaly persistence can serve as a benchmark for model evaluations considering the effect of basin scales and geometric properties of river network of the basin. This study further reiterates that persistence forecasts are hard‐to‐beat methods for larger basin scales at short to medium forecast range. 相似文献
