    Synthetic paints attract a lot of attention due to the width of their usage areas and the amount of excessive use. Particularly, the damage caused to the water by the part remaining from the paint used and disposed of in the environment is visible from time to time. Removal of synthetic dyes used from these waters is an important research topic. In our research, we planned to investigate the removals comparatively by using the biosorbent we developed in different combinations. Therefore, chemiobiosorbent was obtained by modifying it with biosorbent and nanoiron produced from sunflower and chitosan, and reaction medium was created using Methylene Blue (MB), Direct Blue 15 (DB) and Reactive Black 5 (RB) dyes. In addition, dye removals of chemosorption, biosorption, Fenton reaction and reactions under UV under the same optimum conditions were compared to find out which removal was most appropriate. As a result of the reaction, it was observed that UV application contributed significantly to the experimental conditions. It was observed that UV increased the dye removal at varying rates in the range of 0.27-4.42% biosorption and Fenton reactions. Accordingly, it was understood that UV did not have a positive contribution in the Chemobiosorption reaction, which we performed using nanoiron in its structure. Considering the cost evaluation, such studies will contribute to the selection of the preferred method for dye removal.

  • Use of Unmanned Aerial Vehicles In Runway Control (2021-09-22)
    Mehmet Masat Ataturk University

    In this study, an Unmanned Aerial Vehicle (UAV) has been developed in order to ensure that the runway control routinely performed by an apron vehicle is performed in a shorter time, with less cost and more safely experimental studies have been carried out for runway control with this developed UAV. With the developed UAV, test flights were carried out at an airport determined by obtaining the necessary permits in the runway control study, and necessary data were obtained. In the region where the test flight was made, the necessary routine checks were made in the presence of experts who made observations with traditional methods, and the points that would pose problems were determined, and the applicability of the UAV in the runway control was concluded by comparing it with the test flight data.

Research Institute, Jaffna 40000, Sri Lanka Srivijeindran Srithayalan Palmyra (Borassus flabellifer L.) Research Institute, Jaffna 40000, Sri Lanka

    OBJECTIVE: The purpose of this systematic review work is to evaluate, summarize, and document the scientific findings of the pharmacological activities of this plant species.

    MATERIALS AND METHODS: The major electronic databases (Web of Science, Scopus, ScienceDirect, and PubMed) have been employed to identify related publications published from 1900 to July 2021. In this review, only reported pharmacological activities-related publications were considered to extract the data.

    Results: Various parts of this plant species are used to treat various disorders in traditional medicines including various pulmonary complaints, diabetes, and heartburn. Further, compounds such as borassoside A to F, nicotinamide, and uracil have been isolated from various parts of B. flabellifer. Clinical, in vivo, and in vitro pharmacological scientific evidence is currently available, and various parts of B. flabellifer showed antiarthritic, anticancer, antipyretic, hypersensitivity, and immunomodulatory activities. Flower showed the greatest number of pharmacological activities. Hitherto, seven bioactive compounds have been identified from B. flabellifer. Only, some uses of B. flabellifer in traditional medicine have scientific evidence at the moment.

    Conclusion: This review article summarized the available scientific evidence based on pharmacological activities of B. flabellifer. The importance and benefits of this plant species are known for a limited group of people and the significance of B. flabellifer should be understood to sustain this invaluable resource.
