The article is about mathematical motifs of modern interest such as remarkable links and knots that were found at a 6th century
Chennai temple. Introducing these mathematical objectswe discuss their timeless and universal appeal aswell as point to possible
reasons for their symbolic use in ancient Indian temples.
Arul Lakshminarayan is at IITM, Chennai. His research interests lie in classical and quantum chaos, quantum information theory
and computation. Starting out as a mechanical engineer, he moved to more esoteric forms of mechanics and is currently entangled
with chaos. He is also interested in tantra, without the goat sacrifices, etc. 相似文献

Putative Role of Cardio Metabolic Risk Among Poorly Controlled Asthmatics in South Indian Population
Murugaiyan Sathish Babu K. P. Sreesoorya Surendra K. Menon Subiman Saha A. R. Srinivasan S. Arul Vijaya Vani R. Reeta V. Kuzhandai Velu 《Indian journal of clinical biochemistry : IJCB》2017,32(2):225-229
Mortality and morbidity attributed to asthma remains to be the biggest nightmare worldwide. Hence, the study was aimed to compare the cardio metabolic risk factors as assessed by Body mass index (BMI), waist hip ratio (WHR), serum triacylglycerol and uric acid in well controlled and poorly controlled asthmatics and to correlate these parameters with the severity of asthma. A case control study was conducted on 90 subjects who were segregated into well controlled asthmatics (n = 30) and poorly controlled asthmatics (n = 30) who were diagnosed based on Global initiative for Asthma management guidelines and healthy volunteers (n = 30). Centrifuged fasting venous blood samples were used for biochemical analysis, pulmonary function test, BMI, and waist hip ratio (WHR) were measured. The statistical analysis was done using SPSS version 17. There was a significant increase in BMI, WHR, lipid profile, serum uric acid and decrease in forced expiratory volume (FEV1), forced vital capacity (FVC), and FEV1/FVC in poorly controlled asthmatics. There was a significant association between FEV1 and serum uric acid, BMI and Triacylgycerol in poorly controlled asthmatics. Poorly controlled asthmatics have greater risk of developing cardiometabolic problems. Serum uric acid can be used as one of the severity markers in asthma to assess cardio metabolic risk. 相似文献

This paper examines the role played by educational technology in the four social science faculties of the University of Malaya. Some explanation of what is meant by educational technology is first given. This involves considering three approaches to educational technology found in the literature and these provide a convenient frame of reference for examining the situation in the four faculties. The prevailing conception of educational technology in the faculties is the least developed and least comprehensive of the three approaches. Reasons are advanced for changing the existing situation in order to improve the quality of teaching and learning. Recommendations in this direction are made and it is suggested that they are applicable not only to the University of Malaya but similar institutions of higher education as well.Paper presented at the Association of Southeast Asian Institutions of Higher Learning (ASAIHL) Seminar on Modern Technology in ASAIHL Universities, University of Malaya, Kuala Lumpur, October 16–17, 1981. 相似文献

Plastics have much to offer as a modern convenience, but lack of responsible plastic waste management habits can lead to potentially harmful environmental effects. Past environmental initiatives revealed a lack of understanding about youth attitudes towards pro‐environmental issues. [minus]plastic, an online public environmental promotional campaign, encouraged Singaporean youth to recognize the importance of, adopt positive attitudes towards and subsequently adopt the practice of responsible plastic management. We propose the Temporal Incentives Model of Social Influence, based on Prochaska and DiClemente's stages of change model, to guide social campaign design. A pre‐post quantitative research design showed that the pre‐contemplation, contemplation and preparation stages progressed significantly after the campaign. The findings suggest that stimuli incorporating specialized information and small action steps allow migration to successive stages. With the strong presence of internet culture among Singaporean youth, the online medium was found effective in altering the attitudes of the campaign target audience, while exposure to the campaign messages proved useful in encouraging environmental learning among youth. 相似文献

The One Laptop per Child (OLPC) initiative has been at the forefront of introducing low-cost computers in developing countries. We argue that the problem is not as much as a focus on the provision of affordable technologies, but the lack of consideration of deeply contextualized implementation design and the lack of understanding of psychological mechanisms at the user-level that influence learning impact. A longitudinal quasi-experimental design among nine rural Indian primary schools involved pre- and post- experiment measures conducted with both test (n = 126) and control groups (n = 79). The study objective was to prioritize local contexts during technology implementation design in order to attain educational impact in terms of improved learning outcomes for students. The Contextualized-OLPC education project utilized strategies identified by the Technology-Community-Management model to address contextually germane factors of teacher training, unbiased gender access, and local language use. A second objective was to assess impact of technology introduction while countering extant techno-determinist approaches of impact assessment. We first demonstrated that technological knowledge was associated positively with functional literacy. We situated the experiment in the social cognitive theory to demonstrate that computer self-efficacy mediates the relationship between technological literacy attained as a consequence of the Contextualized-OLPC education project and a specific learning outcome, functional literacy. Overall, the research illustrated that giving primacy to mere deployment of OLPC laptops has limited relevance to children, both in use and outcome. In support, the results demonstrated the role of contextualized technology in rural classrooms alongside an understanding of user psychology that influence learning impact. 相似文献
