Jahirul; Mohammad Salahuddin, Abu Zafor The aim of this study is to justify Standard Reactor Analysis Code System (SRAC2006) based on the evaluated nuclear data libraries such as Evaluated Nuclear Data File (ENDF/B-VI.8) and Joint European Fission-Fusion (JEFF- 3.1) for core calculations of 3 MW TRIGA Mark-II Research Reactor at Atomic Energy Research Establishment (AERE), Bangladesh. The study was performed through the analysis of integral parameters of Thermal Reactor Cross section (TRX) and Bettis Atomic Power Laboratory (BAPL) benchmark lattices of thermal reactors. In integral measurements, the thermal reactor lattices TRX-1, TRX-2, BAPL-UO2-1, BAPL-UO2-2 and BAPL-UO2-3 were treated as experimental benchmarks for justifying the SRAC2006 code system. The integral parameters of the said lattices are calculated using the collision probability transport code SRAC-PIJ of the SRAC2006 code system at room temperature 20 0C based on the above libraries. The calculated integral parameters are compared to the measured values as well as the Monte Carlo Nuclear Particle (MCNP) values based on the Chinese Evaluated Nuclear Data Library (CENDL-3.0). It was found that the calculated results show a good agreement among the said data files as well as the experimental and the MCNP results. To enrich this justification study the group constants (in SRAC format) such as activation cross-section, fission cross-section, nu-fission cross-section, total cross-section, diffusion coefficients, absorption cross-section and scattering cross-section in fast and thermal energy range between the above data files for TRX and BAPL lattices were calculated using the SRAC-PIJ code in fixed source mode. By comparing the group constants it was found that the group constants were well consistent with each other. Therefore, this paper reflects the justification study of the SRAC2006 code system and it will be useful to meet up nuclear data for further core safety calculations of 3 MW TRIGA Mark-II research reactors at AERE, Savar, Dhaka, Bangladesh.

Sharif; Rahman, Md. Mahbubar; Karim, Md. Mashud Drag estimation and shape optimization of submarine shaped hulls are important for energy efficiency and hull form improvement. In this study, fluid flow around the 3D DREA bare submarine hull is simulated with the help of finite volume method. Widely implemented Reynolds-averaged Navier-Stokes (RANS) approach and SST k-ω turbulence model with low-Re version are used to represent turbulent transport equations. Computed results are compared with experimental results as well as simulated results of other researchers and found satisfactory. The velocity distribution (vectors, contours and streamlines), pressure distribution and drag coefficient are also analyzed. The result of this study illustrated the flow physics around 3D submarine shaped hull which might be helpful for improvement of design of such underwater bodies. M. Sharif Khan1*, Md.

Ismail; Rahman PhD, Dr. Md. Ferdausur This paper is aimed to scrutinize the existing reporting standard for the Foreign Commercial Banks in Bangladesh and find out the extent of compliance by them. Banking industry’s nature of operation is totally different from others. Recognizing this aspect some specific IFRSs (International Financial Reporting Standards) have been prescribed for them. One of which is IFRS # 7 (Financial Instruments: Disclosures) which was formulated by IASB in 2004 and obliged to comply from on after 1st January, 2007 n the Annual Reporting. Institute of Chartered Accountants of Bangladesh (ICAB) prescribed to comply with IFRS # 7 from on or after 1st January, 2010 in Bangladesh. Hence compliance of IFRS 7 is of immense importance here. Scrutinization has been operated on 9 Foreign Commercial Banks. As per requirement, all the Foreign Commercial Banks are required to comply with the standard to uphold the stakeholders’ interest inspite of possessing the large portion ownership by the Foreigners. And the result of the study shows that all of the Foreign Commercial Banks compliance almost 68.18% of the IFRS # 7 requirements. Finally this study recommend on the degree of compliance for the Foreign Commercial Banks financial reporting. Md. Ismail Hossain(1) and Dr. Md.

Z. The concept of miniaturization originated after the deliberation of a talk given by physicist Richard Feynman on 29th December 1959, led to the development of quantum dot (QD), which is the basic building block of single electron transistor (SET). SET is a new type of switching device used controlled tunneling of electron to amplify current. According to Moor’s law, SET may be alternative of complemented metal oxide semiconductor (CMOS) device for the next generation electronic devices and sensors. This is a review article intended to consolidate the knowledge on the working principle of SET along with relevant other aspects and also highlighting the promising applications with limitation of implementations in the 21st century in order to reduce power dissipation.
