Nantucket: Living with Water
No full textToday, our 2101 world map looks very different from that of 2020. The sea levels have risen more or less by twelve-foot across the globe. Most of the famous beaches of the world have disappeared into the oceans. The coastal cities like Miami, Venice, Mumbai, have become something else entirely - famous diving spots to explore the submerged cities. While atoll islands like the Maldives are lost to the ocean, there are a number of metropolis islands formed by the ocean. With every rising inch of sea level, the water continues to invade more of the coastline, spearing deeper and deeper into the cities. These islands are low-lying cities that are now disconnected from the mainland by ocean. Today the metropolis island of New York City is a hundreds of skyscrapers rising from the ocean interconnected by networks of water canals and skybridges. Like New York City, most of the metropolitan cities around the world exhausted their city budgets to survive with the rising sea. Some strategized to avoid and resist while some to accommodate. Only a few succeeded and these few are still struggling to survive even today, since the same story persists - the global warming is melting ice sheets, and the sea levels are rising. The rising water is engulfing more and more land making continents grow apart
Techno-economic evaluation of bio-hydrogen production: via membrane reforming and cryogenic CO2 separation
No full textTransport sector CO2 emissions are on the rise and responsible for nearly 30% of the EU’s total CO2 emissions (European Parliament,2019). An attractive way to reduce the CO2 emissions by transport is by changing the fuel used. Hydrogen is expected to play a key role in a clean, secure and affordable energy future (IEA). However, a clean, widespread use of hydrogen in global energy transitions faces several challenges. Currently, the global hydrogen production is approximately 7.2 EJ per year, 96% of which comes from fossil fuels. To harness the potential of hydrogen on the way to a clean energy future requires the capture of CO2 from hydrogen production from fossil fuels and greater supplies of hydrogen from renewable energy sources. This study focuses on assessing the techno-economic potential of the membrane technology coupled with carbon capture technology, to produce decentralized bio-hydrogen in realizing a low carbon society in The Netherlands. A literature survey was performed to determine the performance of the membrane reactor & cryogenic capture technologies and expected technological advancements. With the information obtained,a basic process of membrane reforming with carbon capture was modeled in Aspen Plus. Different configurations of the basic process were developed. In the first stage, thermodynamic key performance indicators were used to compare the performance of the different configurations developed. Secondly, one promising configuration was chosen and the levelized cost of hydrogen was used to optimize the process parameters like sweep ratio, permeate pressure, feed pressure etc. Finally, the optimum configuration was used to determine its economic and CO2 emissions potential compared to the conventional steam methane reforming process. Exergy analysis for the optimum configuration was also performed.The optimum levelized cost of hydrogen of the decentralized hydrogen production system developed in this work is calculated to be 4.19 €/kg H2. The levelized cost of hydrogen for the equivalent centralized steam methane reforming system is 5.98 €/kg H2. Therefore, the decentralized system developed is more attractive than the centralized system. The higher costs of the centralized system are due to the hydrogen transportation costs. Furthermore, the carbon capture unit costs 0.68 €/kg H2 and an additional dehydration unit at 0.4 €/kg H2 is required to meet the PEM fuel-cell hydrogen specifications. The efficiency and carbon capture rate of the developed configuration is 66.07% and 72.13% respectively,higher than the conventional process. The exergy efficiency of the developed process is 65.1%. The CO2 emissions for the decentralized system across the value chain are calculated to be 1.4 kg CO2/kg H2. Future scenarios with renewable energy in the electricity mix result in negative CO2 emissions, making the system attractive to limit the climate change and also benefit financially from the EU-ETS. The CO2 emissions of the centralized system are 5.45 kg CO2/kg H2 with post-combustion carbon capture and 10.14 kg CO2/kg H2 with state-of-the-art reforming. With a carbon tax to be implemented soon,the costs of this system will rise making the decentralized system even more attractive. However, uncertainties in the development of an integrated hydrogen transport infrastructure, fuel-grade hydrogen demand, technological advancements in membrane reactors etc. may affect the comparative attractiveness of the systems.Electrical Engineering | Sustainable Energy Technolog

Comparing research trends through author-provided keywords with machine extracted terms: A ML algorithm approach using publications data on neurological disorders
No full textObjective. This study aimed to identify the primary research areas, countries, and organizational involvement in publications on neurological disorders through an analysis of human-assigned keywords. These results were then compared with unsupervised and machine-algorithm-based extracted terms from the title and abstract of the publications to gain knowledge about deficiencies of both techniques. This has enabled us to understand how far machine-derived terms through titles and abstracts can be a substitute for human-assigned keywords of scientific research articles.
Design/Methodology/Approach. While significant research areas on neurological disorders were identified from the author-provided keywords of downloaded publications of Web of Science and PubMed, these results were compared by the terms extracted from titles and abstracts through unsupervised based models like VOSviewer and machine-algorithm-based techniques like YAKE and CounterVectorizer.
Results/Discussion. We observed that the post-covid-19 era witnessed more research on various neurological disorders, but authors still chose more generic terms in the keyword list than specific ones. The unsupervised extraction tool, like VOSviewer, identified many other extraneous and insignificant terms along with significant ones. However, our self-developed machine learning algorithm using CountVectorizer and YAKE provided precise results subject to adding more stop-words in the dictionary of the stop-word list of the NLTK tool kit.
Conclusion. We observed that although author provided keywords play a vital role as they are assigned in a broader sense by the author to increase readability, these concept terms lacked specificity for in-depth analysis. We suggested that the ML algorithm being more compatible with unstructured data was a valid alternative to the author-generated keywords for more accurate results.
Originality/Value. To our knowledge, this is the first-ever study that compared the results of author-provided keywords with machine-extracted terms with real datasets, which may be an essential lead in the machine learning domain. Replicating these techniques with large datasets from different fields may be a valuable knowledge resource for experts and stakeholders
Mój Petersburg
No full textMy PetersburgThe author discusses his emotional attitude to Petersburg, which evolved not through direct contact, but as a result of indirect influence, primarily of his Russian grandmother. Thanks to her he developed a mental image of the city, which in his old age he was able to confront with the reality. Recalling Adam Mickiewicz’s poetic vision, he presents three Poles who were active in Petersburg and who were close to him for various reasons: the lawyer and publisher Włodzimierz Spasowicz, the linguist Jan Baudouin de Courtenay and the entrepreneur Antoni Kulczycki, the author’s grandfather. His family, living in Petersburg, on the Russian-Polish cultural frontier, became completely Polonised after moving to Poland, although fate could have decided otherwise.Translated by Anna Kijak Мой ПетербургАвтор описывает свое эмоциональное отношение к Петербургу, создавшееся не путем непосредственного контакта, а в результате посредственного воздействия, прежде всего русской бабушки.

Termination for breach: the prospects of the <scp>Unidroit</scp> principles of International Commercial Contracts to interpret and supplement the Indian law of contract
No full textAbstract
Predicated on English law, termination for the breach of contract in India is regulated by the Indian Contract Act, 1872 and the Sale of Goods Act, 1930. However, these legislations do not adopt uniform criteria while stipulating the circumstances in which the parties may exercise their right to rescind the contract for breach. The complex nature of the rules on termination for breach has rendered the Indian law of contract unsuitable to govern domestic or transnational agreements. This article examines the plausible role of the International Institute for the Unification of Private Law’s (Unidroit) Principles of International Commercial Contracts (PICC) in developing the Indian law of contract. It argues in favour of a complete overhaul of the legal principles on which the parties’ right to rescind a contract for breach is based on the ground that these reflect a pro-termination instead of a favor contractus approach. Consequently, the author urges Indian lawmakers to consider employing the provisions of the PICC on the subject as a model to develop the law of the Republic to foster international trade and facilitate justice among litigants. Although an amendment to the Indian law of contract would be ideal, the judiciary should, in the meantime, refer to the PICC while adjudicating disputes arising from the breach of contracts to interpret and supplement the Indian law according to well-defined and internationally accepted standards.</jats:p
Reconciling the Pro-Choice Argument with the Anti-Life Rhetoric: Issues in the Indian Context
No full textThe debate concerning the woman’s right to choose versus the right to life of the unborn child is centred around the argument, whether one right can be preferred in lieu of another. The law in India simply prohibits abortion unless carried out within twenty weeks, while remaining silent as to the point when life sprouts in the foetus. Further, abortion can only be carried out under specified conditions determined solely by the medical practitioner and not the woman. In this paper, the author argues that prior to foetal viability (twenty-four weeks into the pregnancy, as per studies), the foetus does not classify as a human person and hence, cannot be endowed with the right to life. Thus, the woman’s right to choose when and whether to terminate her pregnancy must not be encroached upon by the State, unless absolutely necessary to prevent harm to her life or health. This outlook, tied in with the implications of denying the woman her right to choose, although pro-choice in nature, does not reflect an anti-life sentiment. The author contends that a pro-choice view does not necessarily impinge upon the foetus’s right to life
