Tribological Potential of Hybrid Composites Based on Zinc and Aluminium Alloys Reinforced with SiC and Graphite Particles

The paper reviews contemporary research in the area of hybrid composites based on zinc and aluminium alloys reinforced with SiC and graphite particles. Metal matrix composites (MMCs) based on ZA matrix are being increasingly applied as light-weight and wear resistant materials. Aluminium matrix composites with multiple reinforcements (hybrid AMCs)are finding increased applications because of improved mechanical and tribological properties and hence are better substitutes for single reinforced composites. The results of research show that the hybrid composites possess higher hardness, higher tensile strength, better wear resistance and lower coefficient of friction when compared to pure alloys

Evaluation of Watson-like Integrals for Hyper bcc Antiferromagnetic Lattice

Watson-like integrals for a d-dimensional bcc antiferromagnetic lattice I_d(\eta) and J_d(\eta) and another two similar integrals are evaluated in an exact way in terms of generalized hypergeometric functions. A simple formula connecting Id and Jd+1 is given along with the differential equations for I_d(\eta) and J_d(\eta). An application of I_d and J_d in the theory of the Heisenberg antiferromagnet is discussed, together with possible generalizations to non-integer values of d. Corresponding integrals for sc lattices are also briefly reviewed.Comment: 13 pages, 2 figures, Accepted for publication in Journal of Physics A: Mathematical & Theoretical 201

Search for Dark Matter with CRESST

The search for direct interactions of dark matter particles remains one of the most pressing challenges of contemporary experimental physics. A variety of different approaches is required to probe the available parameter space and to meet the technological challenges. Here, we review the experimental efforts towards the detection of direct dark matter interactions using scintillating crystals at cryogenic temperatures. We outline the ideas behind these detectors and describe the principles of their operation. Recent developments are summarized and various results from the search for rare processes are presented. In the search for direct dark matter interactions, the CRESST-II experiment delivers competitive limits, with a sensitivity below 5x10^(-7) pb on the coherent WIMP-nucleon cross section.Comment: Accepted for publication in New Journal of Physics. 25 pages, 18 figure

A Knowledge Base For Teachers on Teacher-Student Relationships

Teacher-student relationships are an important factor in effective learning environments and of specific importance in multicultural classrooms. This chapter presents some of the findings of a research programme that studied for more than 30 years teacher-student relationships. We first summarise the interpersonal perspective on the study of teaching and introduce an instrument to measure perceptions of the teacher-student relationship. Then we present results on the associations of teacher-student relationships and student outcomes, both cognitive and affective and explore how these associations differ for various ethnic groups. After a discussion on changes in the teacher-student relationships in time and developments over the teaching career we discuss common teacher problems in the relationships with their classes with a comparison of problems in mainstream and multicultural classrooms. Finally we delve into teacher-student interact ions that can be considered building blocks for the development of teacher-student relationships with an emphasis on the influence of coercive teacher behaviour in one lesson on teacher-student relationships in consecutive lessons
