Effect of Arsenic Contaminated Drinking Water on Human Chromosome: A Case Study     

Asha Lata Singh  Vipin Kumar Singh  Anushree Srivastava 《Indian journal of clinical biochemistry : IJCB》2013,28(4):422-425

Arsenic contamination of ground water has become a serious problem all over the world. Large number of people from Uttar Pradesh, Bihar and West Bengal of India are suffering due to consumption of arsenic contaminated drinking water. Study was carried out on 30 individuals residing in Ballia District, UP where the maximum concentration of arsenic was observed around 0.37 ppm in drinking water. Blood samples were collected from them to find out the problem related with arsenic. Cytogenetic study of the blood samples indicates that out of 30, two persons developed Klinefelter syndrome.  相似文献   

Combining Work and Learning in the Informal Economy: Implications for Education, Training and Skills Development     

Madhu Singh 《International Review of Education/Internationale Zeitschrift für Erziehungswissenschaft/Revue internationale l'éducation》2000,16(2):599-620

Although education is identified as a key determinant of economic development and poverty eradication, this relationship is only possible when educationists are able to provide a comprehensive picture of the educational process in working life. In this paper it is argued that if systems of education and training are to cater to both the formal and the informal labour markets, then they need to take into account the traditions and values of the system of vocational learning in working life, cater to the requirements of local development and be based on an understanding of the kinds of competencies people in the informal economy want, need and utilise, the socio-economic and cultural contexts within which they work, and how they cope and sustain their livelihood strategies.  相似文献   

Strength and deformation characteristics of steel fibrous concrete beams     

SINGH Bhupinder SINGH S.P KAUSHIK S.K. 《浙江大学学报(A卷英文版)》2007,8(2):257-263

INTRODUCTION Finite Element (FE) procedures are at present widely used in engineering modelling and analysis and employed extensively in the analysis of solids and structures and heat transfer and fluids (Bathe, 1996). The essence of FE solution of an engineering problem is that a set of governing algebraic equations is es-tablished which are then solved with the help of a digital computer. The first practical FE procedures were employed in linear analysis of solids and struc-tures (B…  相似文献   

South-Asian Adolescents in British Schools: A review     

P. A. Singh Ghuman 《Educational studies》2002,28(1):47-59

This paper reviews published research on the education of South Asian young people in the UK. Young people of South Asian ancestry face extra problems of social adjustment at school because of the clash of values between the Asian home and the school and the racism of British society. The review covers important areas of concern, i.e. scholastic achievement, vocational aspirations, entry to higher education, inter-ethnic relations in schools, attitudes of teachers and mother tongue teaching. It is quite clear that South Asian young people in the UK (with the exception of Bangladeshis) are achieving as well as their white counterparts. Indeed, their rate of entry to universities is higher than that of whites. There also appear to be 'good' race relations in British schools as reported by most researchers. However, what emerges from the analysis is that there remain two main areas for concern; namely, the teaching of the mother tongue within the school curriculum and the entrenched negative attitudes (prejudice) of some teachers against South Asians. It is argued that there are wider ramifications of this paper for other ethnic minority adolescents in Europe and elsewhere. The paper concludes by offering some suggestions which might prove useful in this context.  相似文献   

Teacher support,instructional practices,student motivation,and mathematics achievement in high school     

Rongrong Yu  Kusum Singh 《The Journal of educational research》2018,111(1):81-94

The authors examined the relationships among teacher classroom practices, student motivation, and mathematics achievement in high school. The data for this study was drawn from the base-year data of High School Longitudinal Study of 2009. Structural equation modeling method was used to estimate the relationships among variables. The results indicate that conceptual teaching positively affected student mathematics achievement, whereas procedural emphasis in mathematics instruction had a negative effect. Teacher support influenced student mathematics achievement indirectly through students' mathematics self-efficacy, and also influenced students' interest in mathematics courses. Finally, students with higher levels of family socioeconomic status and prior achievement were more likely to have teachers who use conceptual teaching strategies. Students with higher prior achievement were also more likely to perceive higher levels of teacher support. The findings have theoretical and practical implications.  相似文献   

Techniques in X-ray astronomy     

Kulinder Pal Singh 《Resonance》2005,10(7):8-20

The excellent X-ray images produced by X-ray telescopes require the use of detectors with imaging capability at the focal plane of the telescopes. In this concluding part of the article on experimental techniques in X-ray astronomy, I describe many X-ray detectors that have been used over the years. These can broadly be classified into two physical types: non-dispersive and dispersive. Traditionally the simple non-dispersive types have been used extensively in X-ray astronomy. The advancement of solid state technologies, cryogenics, and the quality of X-ray imaging has led to many new detectors of both types. Both the traditional and the new types of detectors are described briefly here with emphasis on principles and some technical details. Kulinder Pal Singh is in the Department of Astronomy and Astrophysics of the Tata Institute of Fundamental Research, Mumbai. His primary fields of research are X-ray studies of hot plasmas in stars, supernova remnants, galaxies, intergalactic medium in clusters of galaxies, active galactic nuclei, cataclysmic variables and X-ray binaries. He is leading the development of a soft X-ray imaging telescope for the ASTROSAT mission to be launched by India in 2007–2008. Part 1.

Towards a research training curriculum: What, Why, How, Who?   总被引：3，自引：0，他引：3  

Erica McWilliam  Parlo Singh 《The Australian Educational Researcher》2002,29(3):3-18

Our purpose in this paper is to investigate the ways in which the work of research higher degree supervision is being reshaped from within and outside universities. Our interest is in the means by which new ‘content’ and ‘process’ knowledge — and thus a new set of pedagogical tasks and relationships — are being configured in the field of higher degree research. The outcomes of research training have traditionally been products of a one-on-one supervisory relationship, that is, academic apprentice-to-disciplinary mentor. This is especially the case in the fields of arts/humanities. Any ‘curriculum’ necessary to such a model has been both implicit and at the discretion of the disciplinary ‘master’.  相似文献   

How is nature asymmetric?     

B. Ananthanarayan  J. Meeraa  Bharti Sharma  Seema Sharma  Ritesh K. Singh 《Resonance》2002,7(6):45-52

This two-part article considers certain fundamental symmetries of nature, namely the discrete symmetries of parity (P), charge conjugation (C) and time reversal (T), and their possible violation. Recent experimental results are discussed in some depth. In this second part, we discussCP andT violation and arrive at a synthesis.  相似文献   

Learning theories and environments: A student-initiated intelligent computer-assisted environment     

Amarjit Singh  Dr. Malcolm Carr 《Research in Science Education》1992,22(1):367-376

Intelligent computer-assisted instructional systems have been constructed and applied within a wide range of fields. Very few of these systems make explicit a central or set of core learning theories or learning environments upon which a system is based. However, many of these systems have implicitly employed learning theories and environments. This paper looks at a variety of intelligent computer-assisted systems with a view towards uncovering the latent learning theories they employ. The interplay of the various learning theories needed to realise a student-initiated learning environment are discussed. The central features required for such an environment to function and the limitations of realising such a learning environment due to the state of the art of present day systems are also discussed. Specializations: physics education; computer education; intelligent computer-assisted instructional systems; physics problem solving. Specializations: chemical education, technology education, history and philosophy of science, learning theories.  相似文献   

Simple models for the 100 meter dash     

Priyanka deSouza  Vijay A. Singh 《Resonance》2012,17(6):592-603

In this section of Resonance, we invite readers to pose questions likely to be raised in a classroom situation. We may 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
