Maximizing Water--Food--Energy Nexus Synergies at Basin Scale
No full textIn this short paper, we show how solutions for mitigating resource security in one sector can be found in another. We demonstrate—by means of a case study in Burkina Faso and Ghana—how investing in the electricity grid in the south leads to increase food security in the north. A new nexus framework was developed (‘MAXUS’) which was built to understand, simulate and optimize intersectoral (and international) development strategies in the water, food and energy sectors. We believe this new type of geospatial integral resource management, supported by the exponential increase of data availability of the twenty-first century, could finally turn nexus models into decision support tools.Green Open Access added to TU Delft Institutional Repository ‘You share, we take care!’ – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Water Resource
Reclamation of Dye Affected Soil at Tirupur Region by Using Vermitechnology, South India
No full textSoil from the dye affected area is taken for various analysis. Similarly soil from the fertile land is also taken for analysis in the same region. Most of the soils polluted by heavy metals can be reclaimed using a number of expensive tactics that either remove the contaminants or stabilize them within the soil .To analyze the parameters such as soil pH, temperature, soil fungal, bacterial and actinomycetes population of both the samples. Find out what are the metals present in the soil samples. Apply vermicompost to the dye affected soil for reclamation. Again we should analyze soil pH, temperature, fungal, bacterial and actinomycetes population of both the soil samples .The results are discussed with the literature.----------------------------------------------------------------------------------V.

Scientometric Portrait of Homi Jehangir Bhabha: The Father of Indian Nuclear Research Programme
No full textQuantitative and qualitative analysis with graphic representation of the publication productivity of a scientist facilitates easy and clear perception about the work of a scientist. Bhabha’s scientific work spanned over more than three decades (1933-1967) during which he published 104 publications, which could be classified into nine fields: Interaction of Radiation with Matter (4), Quantum Electrodynamics (5), Mathematical Physics (2), Cosmic Ray Physics (18), Elementary Particle Physics (14), Field Theory (15), General Physics (2), Nuclear Physics (4) and General (40). The highest number of publications (6) were published in 1941, 1945 and 1964 respectively. The average number of publications published per year was 3.05. His productivity coefficient was 0.05 which is a clear indicates that his publication productivity was quite consistent throughout his scientific career. He was single author in 79 of his publications and the main author in 24 publications indicates that he always preferred to work himself and lead the team as ‘mentor’. Bhabha had 22 collaborators during the period. Team of research collaborators working with a successful scientist documents the sociological aspect of history of science while generating knowledge by a leader in a domain.
Bhabha became a citable author in 1937. Bhabha received 1211 citations to his 30 publications out of 104 publications. Out of 104, 74 publications did not receive any citations. Out of 74 publications, 40 publications dealt subjects mainly of general interest. Bhabha’s 86.66 percent of cited publications received their first citations within four years of their publication indicates that his publications were noticed immediately and had direct impact among the fellow researchers working all over the world. His overall citation rate was 11.64 per cited publication. The highest citations 389 were received to the domain ‘Cosmic ray physics’. The highest number of citations received were 45 in 1938. His self-citations were only 24 (1.98%) and citations by others were 1187 (98.02%). The highest self citations were six in 1946. Bhabha’s mean diachronous self-citation rate was 1.98. The highest citation rate 28.4 was to the domain ‘Quantum electrodynamics. His single authored publications have received the highest number 863 (71.26%) of citations. Bhabha’s five publications have been cited more than 100 times each. His publications have been cited by the authors working in various diverse fields like nuclear physics, mathematical physics, instrumentation, optics, geophysics and geochemistry, condensed matter physics, applied physics, electrical and electronic engineering, mechanical engineering etc., indicating a very diverse influence and impact of Bhabha’s publications. Bhabha’s publications have also been cited by the Nobel laureates like V. L. Ginzberg, Wolfgang Pauli, H. A. Bethe, M. Born, W. Bothe, E. P. Wigner, H. Yukawa, P. M. S. Blackett and C. N. Yang which is an indication of his originality of ideas and high quality of publications

Design with data: Practising exploratory inquiring on data visualisation
No full textIntending to implement a data-enabled design approach to use this data in their creative design process, Ford established a research collaboration with the faculty of Industrial Design Engineering at the Delft University of Technology. As part of the collaboration, several lines of research were carried out, like data strategy, data visualisation, and early prototyping in the form of graduation projects. In one such work, Mellado Cruz (2021) identified that exploratory inquiring as a means to derive insights from data visualisations has great potential in supporting the creative design process. With her empirical studies, she could generate theoretical knowledge about this process; however, bridging work was needed to convert this knowledge into a practical and actionable outcome.In this project, I address the research question, "How can exploratory inquiring on data visualisation be operationalised in the Ford design team to support their creative design process? ". I begin the process with a phase of immersion into theory and context- using published literature about exploratory data analysis,data visualisation, creativity, and design theory to obtain theoretical understanding and the thesis reports of past graduation projects. At the end of this phase, I identify three potential opportunities that can aid in implementing exploratory inquiring in Ford design teams. One of the opportunities- to conceptualise exploratory inquiring as a collaborative design method- was identified as the most feasible in terms of the scope of the project, practical and desirable for the Ford design teams. A preliminary concept method was developed based on the learnings from the literature in line with this direction. This was iteratively prototyped, tested and refined for three cycles in the design iterations phase. The version at the end of the third cycle was used to create the final deliverable- a toolkit consisting of an information booklet that helps in circulating the procedural knowledge of the method within the team to create awareness and canvasses that support the execution of the method. In the last parts of this report, I provide recommendations for future studies to tackle the limitations I faced in this project and possibly inspire new works in the area of data-enabled design.Strategic Product Desig
