Two-body and three-body substructures served as building blocks in small spin-3 condensates

It was found that stable few-body spin-structures, pairs and triplexes, may exist as basic constituents in small spin-3 condensates, and they will play the role as building blocks when the parameters of interaction are appropriate. Specific method is designed to find out these constituents.Comment: 9 pages, 4 figure

Fragmentation of Nuclei at Intermediate and High Energies in Modified Cascade Model

The process of nuclear multifragmentation has been implemented, together with evaporation and fission channels of the disintegration of excited remnants in nucleus-nucleus collisions using percolation theory and the intranuclear cascade model. Colliding nuclei are treated as face--centered--cubic lattices with nucleons occupying the nodes of the lattice. The site--bond percolation model is used. The code can be applied for calculation of the fragmentation of nuclei in spallation and multifragmentation reactions.Comment: 19 pages, 10 figure

Interdisciplinary approaches to zoonotic disease

Zoonotic infections are on the increase worldwide, but most research into the biological, environmental and life science aspects of these infections has been conducted in separation. In this review we bring together contemporary research in these areas to suggest a new, symbiotic framework which recognises the interaction of biological, economic, psychological, and natural and built environmental drivers in zoonotic infection and transmission. In doing so, we propose that some contemporary debates in zoonotic research could be resolved using an expanded framework which explicitly takes into account the combination of motivated and habitual human behaviour, environmental and biological constraints, and their interactions

Ceramic regenerator systems development program

Ceramic regenerator cores are considered that can be used in passenger car gas turbine engines, Stirling engines, and industrial/truck gas turbine engines. Improved materials and design concepts aimed at reducing or eliminating chemical attack were placed on durability tests/in industrial gas turbine engines. A regenerator core made from aluminum silicate shows minimal evidence of chemical attack damage after 7804 hours of engine test at 800 C and another showed little distress after 4983 hours at 982 C. The results obtained in ceramic material screening tests, aerothermodynamic performance tests, stress analysis, cost studies, and material specifications are also included

STEM for Teacher Educators

This project addresses the challenge of enhancing the ability of pre- and in-service teachers to provide STEM education. The goal is to bolster the science, technology and engineering components in K-12 STEM-education by using digital audio and image processing technologies. The intellectual merit and broader impact of this project transcends the scope of the University of Bridgeport and Bridgeport schools, and it includes advanced discovery and understanding, creative and original concepts, extensive resources, participation of under-served populations, and dissemination of technological understanding

Case Study: Development and Assessment of a STEM-Based Course for Teacher Educators

DOI: 10.5923/j.edu.20130303.02It is essential that teachers understand the content of the subjects they teach. A particular challenge in a graduate program for secondary mathematics and science teachers is how to provide teacher candidates with subject matter content, on a graduate level, that does not replicate undergraduate courses. The School of Education and School of Engineering designed a STEM (Science, Technology, Engineering, and Mathematics) course for teacher educators for students of the School of Education. Designed course uses audio and image processing techniques and technologies to teach fundamental STEM concepts to secondary pre- and in- service mathematics and science teachers. Designed to enrich the teaching and learning experience, the course activities include: (a) Lectures and Discussions, (b) Lab activities: Hands-on computer experience, and (c) Team Project. In this paper, we will present the developed course outline, the response of our students who are pre- and in-service teachers, and the lessons learned by the instructors

Conformal thin-sandwich puncture initial data for boosted black holes

We apply the puncture approach to conformal thin-sandwich black-hole initial data. We solve numerically the conformal thin-sandwich puncture (CTSP) equations for a single black hole with non-zero linear momentum. We show that conformally flat solutions for a boosted black hole have the same maximum gravitational radiation content as the corresponding Bowen-York solution in the conformal transverse-traceless decomposition. We find that the physical properties of these data are independent of the free slicing parameter.Comment: 12 pages, 11 figure
