Three phase microcontroller based automatic change-over selection switch

The significance of electricity in a developed country cannot be underestimated because power instability problem affects the economy growth, productivity and infrastructure development. The issues of phase failure, losses and phase imbalance earth fault are main causes that lead to unstable and erratic power supply. Most homes and office complexes where single-phase supply is needed are supplied with three phases of power supply to allow change from one phase to another when there is fluctuation or complete outage of power supply on a particular phase. This operation is normally done manually and has caused a setback in terms of time wastage, strenuous operation, susceptibility to fire outbreak, electric shock and high maintenance frequency. When voltage supply on a phase is below 220V or above 415V, this system automatically disconnects the load from the phase and connects to another where the required condition is met. Therefore, this paper presents a Microcontroller Based Automatic Transfer Switching System which is made up of voltage sensing circuit, Hall Effect current sensor, relays, LEDs and LCD of PIC16F877A microcontroller. A system flow chart was developed, programmed with MikroC software and simulated using Proteus electrical software design. A 10KVA single phase generator was used as alternate power source. The load capacity of the design was determined by decoupling Maxwell’s Equations of 8KW and power loss using pointing vector equation as 0.25% of the peak load. The switch is tested to have function optimally within ±5% nominal voltage of 220 - 415V supply and produced approximately 20 seconds elapses during the entire process of power supply changeover. Hence this device is suitable for Industrial and Domestic use where 3-phase power supply is available with a stand-by power source.

The potential of electrochemical sensors to unveil counterfeits: Xanax as a case study

The illicit drug market has been constantly evolving in the last decades, with a significant rise in counterfeit medicines posing serious public health risks. Benzodiazepines (BZDs) such as alprazolam (generally sold under the brand name Xanax), have particularly become the target of counterfeiting efforts due to their addictive nature and upsurge of unregulated designer BZDs. These counterfeit versions frequently resemble legitimate products but contain harmful adulterants or other potent illicit substances. Few methods have been developed to tackle counterfeit pills, usually limited to accurate and sophisticated laboratory equipment. This study explores the feasibility of combining electrochemical fingerprinting with data analysis to overcome the limitations of traditional methods. First, the electrochemical behavior of selected BZDs is studied, and analytical parameters such as pH are optimized. Then, the electroanalysis of common adulterants and illicit drugs is addressed and integrated into a user-friendly app, including a flowchart system. The proposed electrochemical strategy enables the detection of counterfeit Xanax by identifying the presence or absence of alprazolam. It also allows determination of the alprazolam content within a pill while meeting the fundamental requirements of the end users. This study represents an on-site methodology to address the growing challenges posed by BZDs, easily transferable to counterfeit medicines from other drug groups.

Material flow analysis-based assessment of polypropylene-fiber-containing microplastics released from disposable masks: Characterizing distribution in the environmental media

With the upsurge in the use of disposable masks during the coronavirus disease pandemic, improper disposal of discarded masks and their negative impact on the environment have emerged as major issues. Improperly disposed of masks release various pollutants, particularly microplastic (MP) fibers, which can harm both terrestrial and aquatic ecosystems by interfering with the nutrient cycling, plant growth, and the health and reproductive success of organisms. This study assesses the environmental distribution of polypropylene (PP)-containing MPs, generated from disposable masks, using material flow analysis (MFA). The system flowchart is designed based on the processing efficiency of various compartments in the MFA model. The highest amount of MPs (99.7 %) is found in the landfill and soil compartments. A scenario analysis reveals that waste incineration significantly reduces the amount of MP transferred to landfills. Therefore, considering cogeneration and gradually increasing the incineration treatment rate are crucial to manage the processing load of waste incineration plants and minimize the negative impact of MPs on the environment. The findings provide insights into the potential environmental exposure associated with the improper disposal of waste masks and indicate strategies for sustainable mask disposal and management.
