The Noncommutative Quadratic Stark Effect For The H-Atom

Using both the second order correction of perturbation theory and the exact computation due to Dalgarno-Lewis, we compute the second order noncommutative Stark effect,i.e., shifts in the ground state energy of the hydrogen atom in the noncommutative space in an external electric field. As a side result we also obtain a sum rule for the mean oscillator strength. The energy shift at the lowest order is quadratic in both the electric field and the noncommutative parameter $\theta$. As a result of noncommutative effects the total polarizability of the ground state is no longer diagonal.Comment: 7 pages, no figure

Hubungan Kualitas Pelayanan Karyawan Room Boy dengan Kepuasan Tamu yang Menginap di Hotel Rocky Plaza Padang

The purpose of this study are: (1) Describe the service quality of room boy employess, (2) Describe the customer satisfaction and (3) Analyze the relationship between room boy service quality employee towards customer satisfaction who stay over night Rocky Plaza Hotel Padang.

Studi Awal: Desain Jejaring Kawasan Konservasi Perairan di Pantai Barat Sulawesi Selatan

This study was related to government policies , especially PP No 60 / 2007 article 19 of the mandate of the establishment of network of marine conservation areas in various levels, both local ( provincial ), national, regional and global. One aspect is the establishment of a network of ecological data availability . The method used is the spatial analysis techniques combined with field surveys in the waters of the West Coast of South Sulawesi , especially in the waters of Makassar . Research shows that the condition of each ecosystem ; seagrass with range from 32.5 to 72.5 % with an average of 54 % (Good Condition) condition of coral reef ecosystems which range covered of 17.5 to 57.5 % with an average of 39.5 , % (critical condition ) and condition of mangrove ecosystem with moderate conditions with an area 142 hectares which in the category of denc

Mathematically gifted and talented learners: Theory and practice

This is an Author's Accepted Manuscript of an article published in International Journal of Mathematical Education in Science and Technology, 40(2), 213-228, 2009, copyright Taylor & Francis, available online at: http://www.tandfonline.com/10.1080/00207390802566907.There is growing recognition of the special needs of mathematically gifted learners. This article reviews policy developments and current research and theory on giftedness in mathematics. It includes a discussion of the nature of mathematical ability as well as the factors that make up giftedness in mathematics. The article is set in the context of current developments in Mathematics Education and Gifted Education in the UK and their implications for Science and Technology. It argues that early identification and appropriate provision for younger mathematically promising pupils capitalizes on an intellectual resource which could provide future mathematicans as well as specialists in Science or Technology. Drawing on a Vygotskian framework, it is suggested that the mathematically gifted require appropriate cognitive challenges as well as attitudinally and motivationally enhancing experiences. In the second half of this article we report on an initiative in which we worked with teachers to identify mathematically gifted pupils and to provide effective enrichment support for them, in a number of London Local Authorities. A number of significant issues are raised relating to the identification of mathematical talent, enrichment provision for students and teachers’ professional development
