    Opis:
    Green synthesis of Zinc oxide nanoparticles (ZnO-NPs) is a novel and non-toxic method as compared to the hazardous conventional physical and chemical methods. Herein, we report production of ZnO-NPs for the first time using whole vegetative parts of Sesamum indicum L. The aqueous extracts of various parts of S. indicum were used to synthesize nanoparticles in this study. The synthesized nanoparticles were evaluated using UV-visible spectroscopy for confirmation and characterization. The maximum UV-visible spectral absorption peaks were observed from 293 to 296 nm wavelengths. Leaf and stem reaction mixtures exhibited the sharpest absorption peaks of all the variations at 293 nm and root at 296 nm. This study leads to the development of cost-effective ZnO-NPs synthesis with possible further exploration to serve mankind.

    Opis:
    Justicia betonica L., family Acanthaceae is a widely used traditional folk medicinal herb. It is a unique source of jusbetonin and the leaves yield bluish purple dye. Traditionally, the plant is used to cure constipation, diarrhea, malaria, orchitis, pain, snake bite, stomach ache, vomiting etc. The whole plant possess significant biologically active principles like steroids, triterpenoids, alkaloids, saponins, glycosides, carbohydrates, gum and mucilage, proteins, fixed oils and fat, phenolics and tannins. It is reported to exhibit antiviral, antioxidant, anti-inflammatory, analgesic and antimalarial activities. The intention of the study was to endow an overview of the ethnomedicinal properties, phytochemistry and related pharmacological applications of J. betonica, and to make an authenticated evidence base for further research on this important medicinal plant.

    Opis:
    In this paper, aluminium alloy of grade ADC-12 was considered as a base metal and chromium carbide (Cr3C2) particles were reinforced through friction stir process. A detailed analysis of mechanical property and metallurgical characterization studies were performed to evaluate the surface composite. Remarkable changes were observed in the developed composite due to the mechanical force produced by the stir tool with an increase in hardness. The metallurgical investigation infers that the presence of silica in ADC-12 alloys has undergone mechanical fracture and long needle structure changed to reduced size. On the other hand, at higher tool rotational speed, the uniform distribution of hard particles was confirmed through SEM micrographs. Thus the modified surface composite has produced good mechanical property with high metallurgical qualities.

    Sri Jayawardenapura Kotte canal
    Opis:
    Assessment of temporal variation of the water quality is an essential aspect of evaluating temporary changes in a water body caused by natural or artificial contributions. The study aims to assess the water quality temporal variation and the water quality index over the year from 2010 to 2019. Water sampling was carried out near the bridge of the Kotte canal. Water quality parameters such as pH, electrical conductivity (EC), temperature, dissolved oxygen (DO), ammonia, nitrate, phosphate, and chemical oxygen demand (COD) were determined to assess the quality of water at different periods. It has been calculated based on the standard of the central environmental authority of Sri Lanka. The weighted arithmetic index method has been used to calculate the water quality index. The water quality index of the study area was recorded as good (33.60760) in 2010 and poor in 2013 (56.95663), 2016 (52.37269), and 2019 (69.04417). The study revealed that the water temperature in the canal fluctuates with the time and climate of the area. The EC of the water is registered within the reference range. However, pH, COD, DO, and ammonia are the main water parameters deviating from the reference range. It is observed that the leading causes of the deterioration of water quality are human activities, the illegal discharge of sewage and industrial wastewater, the lack of adequate sanitation facilities, and urban runoff.
