    CONSTRUCTION OF A LOW-POWER RATING FM TRANSMITTER RADIO WITH AUDIO CONSOLE FOR COMMUNITY BROADCAST AND SECURITY ALERT
    (IEEE, 2023) Ajani Adegbenro Sunday; Ogunbode Olusoji Amos; Egbeyale Godwin Babatunde; Odeyemi Charity Segun
    The security challenges experienced in different communities of Nigeria require initiatives from every stakeholder, hence the development of this miniaturized FM transmission console for information dissemination within a localized community. The early transmitter for radio broadcasting was so bulky and laborious that they occupied large space and heavy circuitry. The circuits were mainly designed with valves and other active components, which are responsible for the large size. With the advent of semiconductor materials such as transistors and integrated circuits, electronic equipments are now becoming miniaturized such that small transmitters are now becoming handy and compact. In line with this, a complete radio broadcasting equipment that is compact and locally designed is constructed in this research. The system units are of two categories namely: the audio console for processing voice with music mixer and the transmitter unit where the center frequency is generated. This project is aimed at serving community such as Estates or villages for broadcasting urgent information using a small radio broadcasting FM transmitting at 107.0 MHz with a power rating of 1 watt and covers a distance of 1 kilometer irrespective of directivity. The output audio signal was tested for different hours of the day and production was received with noticeable voice output. The radio broadcasting transmitter can also be used to disseminate information within large industries, hospitals and universities. The constructed device is recommended for security alerts in areas where security challenges are currently taking place in the Nigeria.

    Proposed Non Invasive Detection of Malaria by Spectral Analysis of Light of Varied Wavelengths through the Blood

    Malaria is a significant public health problem in many parts of the world. Accurate diagnosis and control currently relies on the invasive detection of parasitemias in the blood samples. This technique is invasive, increases risk of blood-borne disease transmission, and is uncomfortable for the patient. This research summarizes the diagnostic techniques that have been used to detect malaria in blood samples and their limitations. It is important to understand that noninvasive testing of malaria can provide adequate check and control high malaria rate by promoting early detection and treatment from mild to moderate to serve cases and noninvasive detection will never be achieved without good calibration approach. At this point, we are far away from reaching the aim of noninvasive detection of malaria through blood in the body, with many technical problems yet to be resolved. This research provides information that may be useful for future development of highly efficient non-invasive malaria detection methods.
