Purpose To assess the diversity of leadership bodies member organisations International Council Ophthalmology (ICO) and World Optometry (WCO) in terms of: (1) proportion who are women all world regions, (2) ethnic minority men Eurocentric high-income regions. Methods We undertook a cross-sectional study board members chairs ICO WCO using desk-based assessment organisation websites during Februa...

Reusing waste cooking oil (WCO) as fuel in compression ignition (CI) engine offers a sustainable solution for energy scarcity and environmental protection. WCO n-pentanol ternary blends deliver are attractive prospects utilization bio-components recycled components to moderately substitute diesel fuel. The current study intends investigate the performance emission characteristics of single cyli...

The authorities in Anguilla sought technical assistance from CARTAC to conduct a comprehensive review if its customs legislation. It is recognized that the existing legal framework for outdated and does not have requisite foundation support modernization of Customs. Ministry Finance requested primary legislation be replaced by completely new act based on CARICOM model and, where appropriate con...

Synthesis of the solid bifunctional vanadium-calcium mixed oxides catalyst was accomplished by application a simple physical mixing approach. In this work, we compared catalytic activity CaO and 2%V2O5.CaO catalyst. Various characterization methods, such as X-ray fluorescence (XRF), diffraction (XRD), Fourier transform infrared (FTIR), BET surface area, temperature-programmed desorption (TPD) C...

The catalytic performance of potassium hydroxide supported on alumina (KOH/Al2O3) for transesterification waste cooking oil (WCO) was investigated. XRD, FTIR, and SEM techniques were used to characterize the catalyst after it had been synthesized using wet impregnation method. properties WCO produced biodiesel evaluated. main fatty acids linoleic (45.61%), elaidic (33.86%), palmitic (10.32%), s...

The management of waste cooking oil (WCO) often poses significant challenges. improper disposal WCO results in negative environmental impacts and economic losses. However, from a circular economy perspective, can be recycled used as sustainable feedstock for numerous industrial products, replacing virgin vegetable oils. This approach enables the recovery resources while simultaneously addressin...
