On the Schwarzschild singularity

Rajapaksha, R.L.R.A.S.; de Silva, N. (University of Kelaniya, 2008)

The Schwarzschild ABSTRACT metric d<2�� (1- 2; }'dt' (I-�� t'-r' (d02+sin2 Od��' ) appears to behave badly near r = 2m, where gtt becomes zero, and grr tends to infinity1• There is a pathology in the line element that ...
Coupling Shallow Water Equation with Navier-Stokes Equations: A viscous shallow water model

Karunathilake, N.G.A. (University of Kelaniya, 2008)

The general characteristic of shallow water flows is that the vertical characteristic scale D is essentially smaller than and typical horizontal scale L .i.e. £ := D << 1 . L In many classical derivations, in order to ...
The use of symbols and 'colour' for sports festivals

Ramanyaka, N. (University of Kelaniya, 2008)

The aim of this paper is to discuss the significance of 'Symbols'and the use of 'Colour' at national and international sporting events and festivals. Historical evidence reveals that the symbols and colo��rs were used ...
Structure of primitive Pythagorean triples and the proof of a Fermat's theorem

Jayasinghe, W.J.M.L.P.; Piyadasa, R.A.D. (University of Kelaniya, 2008)

In a short survey of survey of primitive Pythagorean triples (x,y,z) 0 < x < y < z , we have found that one of x, y, z is divisible by 5 and z is not divisible by 3, there are Pythagorean triples whose corresponding ...
A general relativistic solution for the space time generated by a spherical shell with constant uniform density

Wimaladharma, N.A.S.N.; de Silva, N. (University of Kelaniya, 2008)

In this paper we present a general relativistic solution for the space time generated by a spherical shell of uniform density. The Einstein's field equations are solved for a distribution of matter in the form of a ...
Liquid gastric emptying and antral motility in adult asthmatics

Amarasiri, W.A.D.L.; de Silva, H.J.; Ranasinghe, C.P. (University of Kelaniya, 2008)

Introduction: Asthmatics have increased prevalence of gastro-oesophageal reflux disease (GERD). Gastric antral hypomotility may contribute to this. Gastric motility has been little studied in asthma. Objective: To study ...
Singularities of the elastic S-matrix element

Jayasinghe, W.J.M.L.P.; Piyadasa, R.A.D. (University of Kelaniya, 2008)

It is well known that the standard conventional method of integral equations is not able to explain the analyticity of the elastic S-matrix element for the nuclear optical potential including the Coulomb potential. It ...
Influence of Gender on Academic Performance: A Comparative Study between Management and Commerce Undergraduates in the University of Kelaniya, Sri Lanka

Weerakkody, W.A.S.; Ediriweera, A.N. (University of Kelaniya, 2008)

Many studies have been carried out on the factors affecting the students' academic performance in university examinations. Some of these factors have been identified as attendance of lectures, knowledge of English, income ...
A metric which represents a sphere of constant uniform density comprising electrically counterpoised dust

Wimaladharma, N.A.S.N.; de Silva, N. (University of Kelaniya, 2008)

Following the authors who have worked on this problem such Bonnor et.al 1•2 , Wickramasuriya3 and we write the metric which represents a sphere of constant density p = -1-, with suitable units, as ds2 = 47Z" (e(: ))2 ...
The impact of tourism on homosexuality in Sri Lanka: with reference to Bentota coastal belt

WickramaArachchi, W.A.W.L. (University of Kelaniya, 2008)

Tourism is a dynamic and growing industry. It is the fourth largest foreign exchange earner and premier employer in the island. Tourism can be defined as travel for recreational or leisure purposes. But it creates a ...
Exact formula for the sum of the squares of spherical Bessel and Neumann function of the same order

Jayasinghe, W.J.M.L.P.; Piyadasa, R.A.D. (University of Kelaniya, 2008)

The sum of the squares of the spherical Bessel and Neumann function of the same order (SSSBN)is the square of the modulus of the Hankel function when the argument of all function are real, and is very important in ...
An Assessment of the Influence of Fundamental Factors on Share Prices in Sri Lanka

Fernando, G.W.J.S. (University of Kelaniya, 2008)

This study analyses certain fundamental factors which are determinants of equity share prices in Sri Lanka. These factors are earning, growth, leverage, risk and company size. The literature review of the study have ...
Structure of Fermat triples

Piyadasa, R.A.D. (University of Kelaniya, 2008)

The structure of Fermat's triples can be immensely useful in finding a simple proof of Fermata's Last Theorem. In this contribution, the structure of Fermat's triples 1s determined using Fermat's little theorem producing ...
