Effect of Expression Conditions on the Yield of Dika Nut (Irvingia Gabonesis) Oil under Uniaxial Compression

Efficient expression of Dika nut oil from the kernel is required for its subsequent use in producing comparatively cheap lubricant. Various factors responsible for proper oil expression include particle size, moisture content, heating temperature, heating time, pressing pressure and pressing time. Sundried Dika kernel ground to two particle sizes (fine: ≤ 1.4 mm and coarse: between 1.4 and 2.8 mm) were conditioned to moisture content of 3, 6 and 9 wt%. Considered in the study, are heating temperature ranging from 50 to 150oC in steps of 25 degrees Celsius and heating time of 5 to 25 minutes in steps of 5 minutes. Pressing pressure of 5 to 25 MPa in steps of 5 MPa and pressing time of 2 minutes interval were also considered. The maximum oil yield was then correlated with the processing conditions. Test results showed that coarse particle gave higher oil yield. Maximum oil yield of 72.2% of the available oil was obtained at 6% moisture content, heating temperature of 100oC and heating time of 10 minutes. Regression analyses of the oil yield with heating temperature, heating time, and pressing gave r2 values of 0.9678, 0.999 and 0.9128. The processing conditions therefore has significantly influence the quantity of oil obtained from Dika kerne

Sexual offences in a Muslim world: a socio-ethical reflection on Zamfara State (Nigeria) v. Bariya I. Mugazu.

On Friday morning, 29 January 2001, Bariya Ibrahima Mugazu was given 100 lashes. Zamfara state of Nigeria tried and punished this young woman for having had sex unlawfully in the previous year. Until this case between Zamfara state of Nigeria and unmarried Bariya Mugazu, controversies surrounding the full adoption of Islamic law (Shari'ah) in northern Nigeria seemed to have remained only a local issue. Section 10 of the Constitution of the Federal Republic of Nigeria bars any of its federating units from adopting a "state religion". These states are, however, at liberty to adopt any suitable legal regime. So in 1999, when 12 states in the north of the federation opted for theocracy by adopting Shari'ah as state law, the predominantly Muslim public of the region claimed to be acting within the confines of the municipal law in embracing religiously based regimes. As such, the relationship between this religious and legal order and Nigeria's human-rights-friendly constitution remains controversial. Fornication or adultery may well not constitute an offence deserving criminal prosecution in the non-Muslim secular world. As shall be made apparent in this study, however, individuals' sex lives are highly regulated within the world of Islam. Since Islamic regimes strongly condemn fornication and adultery, this paper is concerned with reviewing Zamfara v. Bariya in order to establish whether the case succeeded in reflecting an Islamic concept of justice. If so, to what extent was the administration of justice by Shari'ah court(s) of law in Zamfara consistent with the ideals and teaching of Islam
