Diclofenac (DCF) is a non-steroidal anti-inflammatory drug (NSAID) used to relieve pain in joint-related diseases. It is not completely metabolized after consumption and cannot be easily removed using conventional wastewater treatment. DCF has been detected in water bodies and may pose chronic effects on the endocrines of living organisms even at low-level exposure. Heterogeneous photocatalysis provides an alternative and efficient method of degrading DCF. In this study, the photocatalytic remov...

Nowadays, farmers use municipal solid waste compost (MSWC) as fertilizer on their farmlands. Very scarce information on the quality of MSWC compost is available. As a result, the physiochemical characteristics of compost from ten (10) different dump sites in Sokoto City were evaluated in this study, and the results were compared with standards. According to the findings, the compost has a pH value ranging from 6.78 to 7.47, an electric conductivity between 2.16 to 6.48, organic carbon between (1...

Vinasseisa liquid is produced during the process of fermentation and distillation of molasses for the production of ethanol. This paper studies the conversion of vinasse into valuable materials using laser, and the characterization of the provided products. For this purpose, vinasse sample was dried and combusted for 30 seconds using Nd: YAG laser with wavelength 1064 nm at output power 60 W continuous mode. The product of this process was characterized by an X-ray diffractometer (XRD), Fourier ...

The development of nuclear science and technology has greatly promoted the development of medical, agricultural, industrial and other industries. However, it is inevitable that more and more radiation safety problems are also accompanied. Accurate measurement of nuclear radiation dose is beneficial to the development of radiation safety. In this paper, based on the Optically Stimulated Luminescence (OSL) technology, the medium and coarse quartz tablets of 38 - 63 μm and 74 - 150 μm were prepared...

Physicochemical analysis and fatty acid content of chemical and traditional extracted shea kernel ( Vitellaria paradoxa) from Kwara State Nigeria have been studied. The extraction of shea butter from shea kernel using chemical and traditional techniques as well as its physicochemical analysis reveals that both the chemical extracted shea butter (CSB) and the traditional extracted shea butter (TSB) are very similar in properties save for the odor (slightly choking nutty odor for CSB and sli...

Cannabis sativa finds application in the medical field as an opioid (medical marijuana) and as a recreational drug despite the fact that it is a prohibited drug substance in many countries. Currently, there are reports on the increasing trends in the number of deaths associated with the use of marijuana. Regardless of these dangers, some countries across the world have legalized the sale and use of marijuana for recreational and medicinal purposes. For these reasons, this review seeks to ...

For a landlocked country like Uganda, air transport is centermost to its import-export trade. As such, the aviation industry is important for its economic and political survival since it guarantees access to the outside world. This study reports on the noise and air pollution levels at Entebbe International Airport, Uganda. We found that the airport experiences irregular noise frequencies with the midday having the highest noise intensities that exceed permissible limits of 60 decibels. Carbon d...

Khat is an ancient class C drug substance that is usually consumed for its stimulating effects induced by the intake of psychoactive alkaloids—cathinone and cathine which have been identified as precursors for oral cancer and impotence in men in addition to other health complications. Although khat is legal in Kenya, some countries have outlawed the cultivation, sale and possession of khat as a countermeasure against narcotic and psychotropic substances. The increasing trends in the use of khat ...

The continuing global pandemic of coronavirus disease 2019 (COVID-19) produced via severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has been a Public Health Emergency of International Concern. Even if the main transmission pathways of SARS-CoV-2 are inhalation from person-to-person and aerosol/droplet transmission, it is proved that the viral ribonucleic acid (RNA) could occur in wastewater, proposing the necessity to better comprehend wastewater as possible sources of epidemiologica...
