Occurrence and partial characterization of serine protease inhibitors in the bark extract of some medicinal plants in Sri Lanka
Protease inhibitors play a vital role concerning proteases. Serine proteases are responsible for a variety of physiological processes and pathological conditions. Therefore, recently interest in protease inhibitors has increased, especially from natural sources such as plants. This study aimed at the identification of a potential candidate plant, the development of an assay procedure to detect …
Development of Indian-Almond and Jackfruit Flour-Based Biscuit and Analysis of Proximate, Sensory, and Shelf-Life
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 …
Optimization of Sample Preparation Techniques for the Quantifications of Metal Ions by Atomic Absorption Spectrometry
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, …
Ground Water Profile of a Small Agrarian Watershed on the Foothills of Western Ghats
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, …

Improved Digital Security Applications for Smart Card
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. Security is an important aspect of providing QoS in a MANET environment. Without the protection of a security mechanism, attacks on a QoS distortion system can lead to poor …
