“…NFE values for 0.00% and 0.20% were significantly higher (p<0.05) than those for 0.40% and 0.60%. The decrease might be attributed to the fungi/bacterial complex which hydrolyzed starch into glucose for use by the microorganisms to synthesize fungi/bacteria biomass rich in protein (Oboh 2002;Osman, 2011). Similarly, gross energy increased with increasing levels of baker's yeast.…”

This study was conducted to determine the physico-chemical composition of cassava peel meal fermented with varying levels of baker's yeast. Fresh cassava peels (CPM) were milled and divided into four groups and each group was randomly assigned toAngel baker's yeast at 0.0%, 0.2%, 0.4% and 0.6%, respectively. Each group (0.00%, 0.20%, 0.40% and 0.60%) was further divided into four subgroups and each subgroup again randomly assigned to 0- hours, 24 hours, 48 hours and 72 hours fermentation duration, respectively in a 4x4 factorial arrangement of a completely randomized design (CRD). The treated CPM samples were thereafter sundried, analysed for proximate and gross energy composition as well as Bulk density (BD) and water holding capacity (WHC). Results from this study indicated a significant (p

“…Traders can join the trading system as a seller or buyer or both. The trading system does not limit its participating parties to engage in ad hoc mcommerce transactions only, but it allows the traders to communicate and collaborate with each other to control and manage its group membership management (Osman and Taylor, 2010) and security and trust service (Osman and Taylor, 2011) which include the following:…”

“…The sanction mechanism will be a significant incentive for traders to desist from behavior that creates negative evidence that other traders can use as a basis for excluding them from a trading forum's membership. The proposed identity support scheme (Osman and Taylor, 2011) will also make it difficult for them to reenter with a whitewashed new identity once they are excluded.…”

Trust development among traders in an ad hoc m-commerce trading system is vital to mitigate uncertainty and risks involved in transactions. It helps traders decide whether to trade with potential trading partners as well as to gauge the degree of confidence that they should give these parties. One way to facilitate such trust is through use of a reputation system. However, the potential for ill-intentioned traders to subvert the reputation system makes the task challenging. This paper discusses key issues in designing a reputation system that can effectively facilitate trust development in such a loose and dynamic trading community. It proposes a fully distributed approach that employs a sanction-backed mechanism to encourage traders to be truthful in providing reputation reports. It advocates letting traders maintain their own reputation information as well as share knowledge about other traders' trading behavior in a peer-to-peer (P2P) manner without relying on network services that are always available. A security analysis on the proposed design shows that it can help traders detect or mitigate the identified misbehavior-related threats to a sufficient degree.
