Anil Kumar Lala (1950–2004)
No full textAnil Kumar Lala, Professor of Chemistry at the Indian Institute of Technology (IIT), Bombay died on 17 July 2004, following a stroke that he suffered three weeks earlier. Born on 13 January 1950, Lala did his B Sc from Delhi University and obtained his Ph D in 1974,working under the supervision of A. B. Kulkarni at Bombay University. His doctoral work was in the area of steroid chemistry, introducing him to the areas of NMR spectroscopy and mass spectrometry. Following a year at the Central Drug Research Institute in Lucknow, Lala moved to the State University of Ghent, Belgium,to work with Marc Anteunis. I first saw his name in a scientific publication,when the conformational analysis of methionine enkephalin, then recently discovered as the endogeneous ligand for the opioid receptor, was described by the French and Belgian groups, with Lala as a co-author (Roques, B. P. et al., Nature,1976, 262, 778). In 1976, he moved to Harvard University to work with Konrad Bloch and it is this period, which sparked his lifelong interest in membranes, specifically lipid–protein interactions. Lala joined the chemistry department at IIT,Mumbai in 1979 and it was here that he spent the remaining 25 years of his scientific career

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.

Yang which is an indication of his originality of ideas and high quality of publications
Comprehensive survey on nanobiomaterials for bone tissue engineering applications
No full textOne of the most important ideas ever produced by the application of materials science to the medical field is the notion of biomaterials. The nanostructured biomaterials play a crucial role in the development of new treatment strategies including not only the replacement of tissues and organs, but also repair and regeneration. They are designed to interact with damaged or injured tissues to induce regeneration, or as a forest for the production of laboratory tissues, so they must be micro-environmentally sensitive. The existing materials have many limitations, including impaired cell attachment, proliferation, and toxicity. Nanotechnology may open new avenues to bone tissue engineering by forming new assemblies similar in size and shape to the existing hierarchical bone structure. Organic and inorganic nanobiomaterials are increasingly used for bone tissue engineering applications because they may allow to overcome some of the current restrictions entailed by bone regeneration methods. This review covers the applications of different organic and inorganic nanobiomaterials in the field of hard tissue engineering

Design of 10-Bit Dual Slope ADC for ISFET based pH Meter
No full textM. Tech. (VLSI Design and CAD)In this thesis work, a 10-bit Dual slope ADC for ISFET based pH sensor has been designed which consumes low power and have high resolution. This is implemented and simulated with Cadence tool in UMC 0.18μm technology with a 3.3V power supply. Different types of ADC are given in literature and they are used according to the intended application. In the biomedical field, accuracy is main concern so dual slope ADC is a best choice. Dual slope ADC is very popular due to its simplicity and higher accuracy. In this ADC there is no need of any DAC which reduces the cost of ADC.
In ISFET based pH meter, a discrete value is available to the input of ADC corresponding to the pH solution so there is no requirement of any sample and hold circuitry. This ADC has three main components: Integrator, comparator and control logic. In the ISFET based pH meter input to the integrator comes from the temperature compensation circuitry, which has upper range output so for an integrator design, an N-channel input two stage operational amplifier is taken in use because an n channel-input two stage operational amplifier have ICMR near to power supply and provide high gain. To achieve the high resolution, a cascaded comparator has been designed which enhance the resolution while keeping the ability of low power consumption. For controlling the whole operation of ADC, Melay state machine based control logic has been designed.
To display the digital output of ADC on LCD, a 3 ½ LCD display driver circuitry has been designed. This LCD display, shows the value of pH from 2 to 12.
Layouts of all the components have been designed and post layout simulation and process corner simulation has done successfully.DIT (Govt. of India) through SMDP VLSI Project, CEERI Pilani and Electronics and Communication Engineering Department, Thapar University
Minimum impact and immediacy of citations to physics open archives of arXiv.org: Science Citation Index based reports
No full textThe present work has calculated the minimum Open Archive Impact Factors and Open Archive Immediacy Index for the Physics Classes of arXiv.org as calculated for traditional journals in Journal Citation Reports of Institute of Scientific Information using Science Citation Index without the citation by the classes itself. The calculated Impact Factors reveal that High-Energy Physics classes of arXiv.org (‘hep-th’, ‘hep-lat’, ‘hep-ex’, and ‘hep-ph’) have made more impact on scientific community than any other classes except for the class ‘nucl-ex’. The Impact Factors for the year 2003 are: ‘hep-th’ (0.999), ‘nucl-ex’ (0.806), ‘hep-lat’ (0.766), ‘hep-ex’ (0.73), ‘hep-ph’ (0.719), ‘nucl-th’ (0.338), ‘quant-ph’ (0.334), ‘cond-mat’ (0.313), ‘astro-ph’ (0.195), ‘math-ph’ (0.162), ‘physics’ (0.061), and ‘gr-qc’ (0.002). It has been found that if the period for getting the citations to the open archive classes is considered one year as against two years for journal articles the rank of the classes are same. The immediacy of citing the Open Archives is also high for the High-Energy Physics classes. The Immediacy Indexes for the year 2003 are: ‘hep-ex’ (0.619), ‘hep-th’ (0.454), ‘hep-ph’ (0.44), ‘hep-lat’ (0.263), ‘nucl-ex’ (0.238), ‘quant-ph’ (0.202), ‘nucl-th’ (0.185), ‘cond-mat’ (0.168), ‘astro-ph’ (0.094), ‘math-ph’ (0.075), ‘physics’ (0.03), and ‘gr-qc’ (0.002). Definitely, the impact is much more than what is concluded from the calculated factors as the self-citations are not taken into the study. The above arguments may be strengthened if the study could use the web-tools like ‘Citebase’, ‘Citeseer’ etc
