Developing a mathematical mode to provide an advanced perspective for realizing the complex nature of the disease and creating realistic care with preventive measures.
Identify the most suitable mathematical model to characterize the alcohol production dynamics of indigenous yeast during spontaneous wine fermentation, with a specific focus on Sri Lanka’s wine industry.
Dengue is a rapidly emerging pandemic disease in many parts of the world, especially in tropical and non-tropical areas. The dengue outbreak has a multisectoral impact on the medical, societal, economical, and political sectors. Dengue incidence has increased in Sri Lanka over the past 20 years, with deaths and illnesses. Almost all the districts i...
Dengue is a rapidly emerging pandemic disease in many parts of the world, especially in tropical and non-tropical areas. The dengue outbreak has a multisectoral impact on the medical, societal, economic, and political sectors. The main economic impact of dengue is due to production costs.
In this study, a SIR model for the human population and SI m...
Living things frequently come into contact with a wide range of harmful pollutants, including
polyaromatic hydrocarbons (PAHs) like anthracene, which are highly carcinogenic and
genotoxic. Microbial degradation is the most promising approach for removing anthracene from
the environment, using microorganisms to transform it into nontoxic compounds,...
Polyaromatic hydrocarbons (PAHs) released from vehicular emissions
and oil refineries deposit on the phyllosphere, compromising the
quality of leaf-based food products by posing many health issues.
Nevertheless, the tea phyllosphere harbours a variety of endophytes
that are highly effective at degrading polyaromatic hydrocarbons,
anthracene, and py...
Plant diseases can cause a significant impact on agricultural productivity. One of the main causative factors for plant diseases is pathogens. Plant pathogens can be fungi, bacteria, viruses, or nematodes. Plant diseases can be prevented, mitigated, or controlled by using a variety of methods. Among these methods, bio-controlling is more effective...
In order to develop a simple and short analytical proof of Fermat's last theorem based on the identity x+y-z where x, y and z are independent variables of the equation corresponding to Fermat's last theorem, we have examined the most suitable property of x+y-z for our purpose.
Kinematics of Basketball free-throw Shooting
Investigation of a best fitting mathematical model for the frequency of occurrence of Trichoderma harzianum in Hakgala Montane Forest in Sri Lanka.
Viscous airflow connected to a compressed Air-shoe

Viscous concentric airflow in between two parallel circular discs has been considered. Since the gap in between the plates is small, Prandtl boundary-layer equations were used to explain the flow. In or...
Confirmation of earth’s closed loop orbit using tidal waves
The present study was carried out in an attempt to observe and analyze the tidal height changes due to the motion of the Sun, Moon and Earth, in the West coastal area of Sri Lanka. Tidal height variations from the Mean Sea Level (MSL) were measured every 15 minutes throughout the year 2015 using the tide pole installed in the sea, 100m away from Co...
This study presents a graph theoretical approach to identify the traffic congestion on a road network. Problem address on a city called Kiribathgoda situated in the western province of Sri Lanka. In the analysis of social networks, centrality measures played a vital role to identify the central nodes in a given network. We look at the applicability...
In this study primitive Pythagorean triples have been carefully examined and found that all of them satisfy a simple rule related to mean value theorem. It is pointed out that integral triples satisfying the equation on Fermat's Last Theorem should satisfy a special rule related to mean value theorem. A conjecture is proposed which may lead to find...
Anomalous absorption of light ion partial waves by the nuclear optical potential is an interesting phenomenon showing striking systematic in various parameter planes. However, the theoretical description of this phenomenon is extremely difficult. In this contribution, we address the problem of its physical interpretation. It is shown that the zero...
We consider a cylindric ball mill, filled with small hardmetal balls and a suspension. By rotating the cylinder around its main-axis the suspension shall be mixed by the balls, which are lifted up on one side and then roll or fall back onto their own surface. The lifting is increased by nine steel bars along the cylinder wall. The problem is that t...
