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...

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...

In spite of the considerable development registered in microbiology, humankind remains incapable to dominate scientifically and technologically the large microbial world. This is well established and illustrated, unfortunately, in the present Coronavirus disease (COVID-19) pandemic. This work aims to contribute to highlighting the world of pathogenic microorganisms, especially viruses, and their removal from potable water. Identical to the manner by which chemical contaminants are handled in the...

Toxicity of zinc, cadmium and phenol and their binary mixtures were determined based on inhibition of dehydrogenase activities of yeasts strains isolated from hydrocarbon impacted soil. The yeasts isolated from the hydrocarbon impacted soil were identified as Saprochaete sp. and Cryptococcus sp. The toxicity of chemicals and their mixtures were evaluated in the concentration range of 0 - 16 mM for phenol, 0 - 5 mM for zinc and 0 - 0.4 mM for cadmium. The binary mixture ratios were evaluated. The...
