Indian almond (Terminalia catappa) and jackfruit (Artocarpus heterophyllus) are widely grown fruits in Sri Lanka, yet the market lacks value-added products incorporating these. This research aims to address this gap by developing biscuit formulations using Indian almond and jackfruit flour. Six biscuit samples were prepared using varying ratios of Indian almond flour, jackfruit flour, and … Read more

Sample preparation is a crucial analytical tool that significantly contributes to the accuracy of analytical methods such as flame atomic absorption spectroscopy (FAAS), electrothermal atomic absorption spectrometry (ETAAS), and inductively coupled plasma optical emission spectroscopy. Therefore, analytical chemists focus on developing sample preparation methods to enhance the sensitivity of these technique measurements. To achieve this, … Read more

Groundwater is the most tapped fresh water source. Timely availability is the reason for its reliability. Temporal groundwater fluctuations are quite natural aspects perhaps never be ignored hydrologically. This work demonstrates the heterogeneity in groundwater levels and predicts the levels for a small agrarian catchment for a rivulet named Ujire Halla. About 25 water wells, … Read more

With the rapid expansion of wireless networks and mobile computing applications, the quality of service (QoS) of mobile ad hoc networks (MANETs) has received increasing attention.
