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

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.

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

The Website is the trademark of the modern distance education (DE) system as DE is vastly dependent on the World Wide Web in delivering academic programs and student support services. DE authorities and administrators should make every effort to ensure that their Web interfaces are intuitive and easy to use for supplying “any time, any place” service. Unfortunately, we distance educators in Asia are far behind our Western counterparts in this aspect. This article explores the level of accessibility of Websites of members of the Asian Association of Open Universities (AAOU) in order to provide the results to the Asian DE authorities. The author's primary objectives in writing this article are to highlight the importance of Web accessibility for distance education institutions and their libraries in catering to a wide range of user groups and to point out how easily barrier-free Websites can be created if the basic rules of Web accessibility are followed. 相似文献

Indian Agricultural Libraries are exploring new ways and collaborations to fullfil the information need of their patrons through resource sharing and delivering documents using online platform accessible 24X7. The article discusses Inter Lendig and Document Delivery Services (DDR) facilitated through a collaborative consortium Journal Gateway called CeRA under Indian National Agricultural Research System. CeRA the (Consortium for e-Resources in Agriculture) provides a platform for online acess to e-journals and inter lending. DDR Services has been established to share resources subscribed by individual libraries as well as consortium journals using the web portal. The article also discusses of the use of DDR services by patrons of the first Indian Agricultural University in the country. Reports that the student community were most active in using the platform for inter library loan and document request in comparison to the faculty researchers who were less dependent on document from other libraries. 相似文献

Plant Growth Promoting Rhizobacteria 总被引:1,自引:0,他引:1
Jay Shankar Singh 《Resonance》2013,18(3):275-281
Plant Growth Promoting Rhizobacteria (PGPR) are a group of bacteria that enhances plant growth and yield via various plant growth promoting substances as well as biofertilizers. Given the negative environmental impact of artificial fertilizers and their increasing costs, the use of beneficial soil microorganisms such as PGPR for sustainable and safe agriculture has increased globally during the last couple of decades. PGPR as biofertilizers are well recognized as efficient soil microbes for sustainable agriculture and hold great promise in the improvement of agriculture yields. 相似文献

This phenomenological study investigated the experiences of 8 Black students enrolled in a master's‐level counseling program. Five themes central to participant experiences were identified: (a) isolation as a Black student, (b) tokenization as a Black student, (c) lack of inclusion of Black counselor perspectives within course work, (d) differences between support received by faculty of color and support received by White faculty, and (e) access to support from people of color and White peers. Implications for counselor educators and study limitations are discussed. 相似文献
