Scientific visualization refers to the study and design of visual representation of data that arises in science and engineering disciplines. The aim of the visualization is the identification of patterns leading to a better understanding of the underlying phenomena. This article will briefly introduce this topic by first providing the motivation in the form of applications, next describing a couple of well-studied visualization methods and algorithms, outlining some of the current research challenges in this area, and finally presenting a summary of related ongoing research work IISc Bangalore. 相似文献

In this section of Resonance, we invite readers to pose questions likely to be raised in a classroom situation. Wemay suggest strategies for dealing with
them, or invite responses, or both. “Classroom” is equally a forum for raising broader issues and sharing personal experiences
and viewpoints on matters related to teaching and learning science. 相似文献

Hemoglobin J-Rajappen (alpha)90 Lys → Thr is an alpha chain variant found in heterozygous state and presents normal hematological blood picture. Due to the ambiguity in results obtained while analyzing by HPLC and alkaline gel electrophoresis, we report this rare case of HbJ-Rajappen using non denaturing gel electrophoresis and matrix assisted laser desorption ionization mass spectrometry. Though HbJ-Rajappen has earlier been reported using different techniques, this is the first report being validated using mass spectrometry technique. 相似文献

Ever since its isolation in 1820, Quinine has played a crucial role in the development of organic chemistry, chemical industry
and modern medicine. The total synthesis of quinine, widely regarded as anevent of epochal importancewas claimed by Woodward
and Doering in 1945. This work, however, heavily relied on unsubstantiated literature reports and it appears that Woodward’s
work fell short of a total synthesis of quinine. The first stereoselective total synthesis of quinine was accomplished only
in 2001, by Stork, who incidentally is the originator of the concept of stereoselectivity in total synthesis. Naturally, this
work has been attested as a landmark in organic synthesis by leaders in the field. 相似文献

The operation of digital microfluidic devices with water droplets manipulated by electrowetting is critically dependent on the static and dynamic stability and lubrication properties of the oil films that separate the droplets from the solid surfaces. The factors determining the stability of the films and preventing surface fouling in such systems are not yet thoroughly understood and were experimentally investigated in this study. The experiments were performed using a standard digital microfluidic cartridge in which water droplets enclosed in a thin, oil-filled gap were transported over an array of electrodes. Stable, continuous oil films separated the droplets from the surfaces when the droplets were stationary. During droplet transport, capillary waves formed in the films on the electrode surfaces as the oil menisci receded. The waves evolved into dome-shaped oil lenses. Droplet deformation and oil displacement caused the films at the surface opposite the electrode array to transform into dimples of oil trapped over the centers of the droplets. Lower actuation voltages were associated with slower film thinning and formation of fewer, but larger, oil lenses. Lower ac frequencies induced oscillations in the droplets that caused the films to rupture. Films were also destabilized by addition of surfactants to the oil or droplet phases. Such a comprehensive understanding of the oil film behavior will enable more robust electrowetting-actuated lab-on-a-chip devices through prevention of loss of species from droplets and contamination of surfaces at points where films may break. 相似文献

We report a case of hemolytic anemia that was subsequently identified to be a case of α-thalassaemia harboring the common rightward 3.7 kb deletion/HbH. The diagnosis was based on sequential analyses using BioRad D10 HPLC, Alkaline gel electrophoresis, GPO α THAL-IC strips and the identification of the specific genetic lesion using an α Globin reverse dot blot hybridization assay. Supravital stain of RBCs helped in identifying classical HbH inclusions. In a background of a variable clinical presentation, lack of definitive hematological markers, and general under-diagnosis of α-thalassaemias we have used this case to highlight the features and sequence of techniques involved in identifying and characterizing an α-globin chain mutation, starting from a diffuse clinical history and presentation up to the identification of a specific genetic lesion involved. 相似文献

The International Physics Olympiad was held in Padua, Italy during July 18–27 1999. It marked India’s second foray into this exciting event where sixty-two nations participated. As the pedagogical leader of the Indian team at Padua, I was privileged to be in the thick of action. Our performance was creditable: all our participants won medals, garnering four silvers and one bronze. Out of the five special prizes, one went to a member of our team. This article describes an interesting and historically rich problem that was posed as part of the five hour theoretical examination. 相似文献

This paper offers an interim analysis of written feedback on a first draft of a PhD thesis. It first looks at two sources of data: in-text feedback and overall feedback. Looking at how language is used in its situational context, we then coded the feedback and developed a model for analysis based on three fundamental functions of speech: referential, directive and expressive. It was found that expressive feedback benefited the supervisee the most. The interaction between the supervisor and the supervisee played an important role for the induction of the supervisee into the academic community, and suggests a peer-to-peer model in PhD education. Finally, this paper suggests the possibility of developing a taxonomy of good feedback practices in postgraduate supervision practice in Higher Education. 相似文献
