Jordan Generalized k-Derivations of Completely Prime ΓN-Rings

Corresponding Author : Sujoy Chakraborty (sujoy_chbty@yahoo.com)

Abstract :

In the theory of gamma rings, it is evident that every generalized k-derivation of a Γ-ring M is a Jordan generalized k-derivation of M. Here we show, in particular, that its converse is also true if one chooses M as a 2-torsion free completely prime ΓN-ring.

Of Boullée and Kahn, and the Spirit of the Sublime

Corresponding Author : K. Taufiq Elahi (elahi-arc@sust.edu)

Abstract :

If we look at the string of development-trend in architectural history and theory in a broader spectrum, it would have been seen that two diverse but distinctive ideals have waged war against one another throughout the centuries. The rationalists were the pioneers amongst the two – as far into the past as texts were found on building art and its relevant issues – they sought for absolute truth and beauty in every object of creation, believing in their hearts that…

Spatial Distributions of the Axis of Coherent Fine Scale Eddies in Turbulence

Corresponding Author : M. Ashraf Uddin (auddin-mat@sust.edu)

Abstract :

Spatial distributions of axis of coherent fine scale eddies in turbulence are discussed by using visualization with some physical insights. The axes are determined from DNS data of decaying homogeneous isotropic turbulence up to Reλ =87.9. Visualizations of the axes in the volume unit of integral length scale (lE), Taylor microscale (λ) and Kolmogorov microscale (η) are compared by selecting the visualized width of axes as constant value, square root of Qc * and Qc * , respectively, where Qc…

SUMono: A Representative Modern Bengali Corpus

Corresponding Author : Md. Abdullah Al Mumin (mumin-cse@sust.edu)

Abstract :

The development of Language Engineering applications requires availability of sizable, reliable and representative corpora. However, such corpora are not routinely available for Bengali language. This paper introduces Shahjalal University Monolingual (SUMono) corpus, a representative modern Bengali corpus consisting of more than 27 million words, which is the largest of its kind. This paper describes how we have constructed SUMono corpus from available online and offline Bengali texts, with articles tagged as belonging to 6 domains: Natural Science, Social Science, Computer…

Unit-Regular -rings

Corresponding Author : Md. Mahbubur Rashid (mrashid_math@yahoo.com)

Abstract :

The object of this paper is to characterize the unit-regular Γ- rings. In this paper we prove some basic properties of regular gamma rings and develop a number of equivalent characterizations of the unit regularity of regular Γ-rings. We finally prove that the class of all unit-regular Γ-rings is a radical class.

Causes of Subsidence In and Around the Baropukuria Coal Mining Area, Dinajpur, Bangladesh: Insight f

Corresponding Author : M. Farhad Howladar (dmfh75@yahoo.com)

Abstract :

The subsidence around the Baropukuria Coal Mine field is the most important and major hazards or threats for safely extracting the coal from underground. From this point of view, the present research mainly investigated the causes of subsidence and its possible preventive plans by direct field investigation method. The analysis shows that subsidence is caused by many factors such as applied mining method, multi-sliced ultra thick coal seams, less competency of overburden strata, depth & dip of the coal seam,…

Natural Gas Properties Analysis of Bangladesh: A Case Study of Titas Gas Field

Corresponding Author : Mohammad Islam Miah (dmfh75@yahoo.com)

Abstract :

Titas is the largest gas field in Bangladesh and the highest gas producer in the country at present which was discovered in 1962 by Shell Oil Company, Pakistan. In designing gas production, processing, transport and handling systems, a complete knowledge of natural gas properties is crucial. For this reason, a detailed research has been done for the measurement and prediction of hydrocarbon fluid properties. This research shows the reservoir of natural gas properties analysis of Titas gas field from gas…

Synthesis and Characterization of a Bis(silyl) compound Based on O-Heterocyclic Aromatics

Corresponding Author : Rockshana Begum (rockshana-che@sust.edu)

Abstract :

A new bis(silyl) compound based on O-heterocyclic aromatics with the dibenzofuran backbone was prepared by dilithiation of the 4,5-positions of dibenzofuran using n-BuLi in the presence of tetramethylethylenediamine (TMEDA) followed by treatment with chlorodimethylsilane. The product DBFsil2 was characterized by 1H NMR, 13C NMR, 29Si NMR, Mass (EI) and Elemental analysis.
