This study investigates the nutritional and anti-nutrient profiles of extrudates produced from seven formulations of pearl millet and Bambara groundnut flour in seven different ratios: 20:80, 30:70, 40:60, 50:50, 60:40, 70:30, and 80:20, with 100% pearl millet and 100% Bambara groundnut extrudates used as controls. The extrudates were processed using a twin screw extruder and analyzed for their nutritional and anti-nutritional properties. The findings revealed a rising pattern in the content of fiber, moisture, protein, ash and fat as the substitution of Bambara groundnut increased in the extrudate.

Article Synopsis
  • Harm reduction for people who use drugs (PWUD) is a key strategy in US drug policy, focusing on meeting communities’ needs and providing various support services.
  • The Block-by-Block (BXB) intervention, launched in 2022 across five pilot areas in Illinois, aims to distribute naloxone and drug test strips in private or neutral settings to reduce opioid-related fatalities.
  • Early results show that the BXB initiative is feasible, with a 55% response rate at homes approached, and high acceptability, as 75% of those who answered were supportive of the intervention.

Plastic waste poses a significant challenge to achieving sustainable production and consumption of resources, particularly in sub-Saharan Africa where effective governance and waste management systems are lacking. In this paper, we develop an empirical understanding of the influence of public governance system on promoting circular economy (CE) for plastic actions among individuals. Through a survey of 1475 participants across five sub-Saharan African countries, we tested five hypotheses drawing on New Governance Theory and CE Action Recipe to explore the relationship between governance and individual's actions supporting CE for plastic.

In a bid to improve entrepreneurial outcomes of graduates from Nigerian universities, the Nigerian government has launched a range of interventions, including a 2004 national policy mandating compulsory inclusion of entrepreneurship education in the curriculum, and support for the establishment and implementation of entrepreneurship development activities by university departments. However, not much is known about the operational nuances, challenges and impact cases that characterise the implementation of this national policy in such a vast, culturally diverse country as Nigeria. To address this lacuna, this study draws on qualitative data from five focus groups, crystalised with quantitative data from 151 students across four Nigerian Universities, to explicate the current trends, successes, and challenges of entrepreneurship development and innovation support in Nigerian universities.

Considering the sustainability of material development, coordination polymerization catalysts effective for 1,1-disubstituted olefins are receiving a great deal of attention because they can introduce a variety of plant-derived comonomers, such as β-pinene and limonene, into polyolefins. However, due to their sterically encumbered property, incorporating these monomers is difficult. Herein, we succeeded in the copolymerization of ethylene with various hydroxy- or siloxy-substituted vinylidenes using a fluorenylamido-ligated titanium catalyst-MMAO system.
