The desert date seeds were collected from Gomo, washed, decocted, dried, and pulverized. The seed oil was extracted using soxhlet apparatus with n- hexane as solvent. The percentage yield of the extracted oil was found to be 40.5%. While the physicochemical analysis of the seed oil was conducted using standard procedures with the following results; specific density 0.98g/cm3, saponification value 134mgKOH/g, peroxide value 38meq/kg, acid value 12.6mgKOH/g, free fatty acid value 12.7mgKOH/g. These results indicate that Desert date seed oil could be a rich source of oil for industrial and domestic purposes if exploited richly.

The advancement in science and technology has led to the detection of diseases affecting humans, and those which could give room to more diseases if it is not matched with a couple that is not suitable. The level of marriage conducted in Nasarawa State without pre-marital test is becoming alarming.

Being a field survey, the study collected data from both primary and secondary sources. A total of 100 respondents 33 from each of the three senatorial zones were selected through random sampling.

The interest of this paper is to examine the controllability and observability of a control system in the configuration state-space of an uncertain optimal control system. The control system is designed based on the realization of capital asset values where a special case of asset management is modelled and optimized. Thus some necessary and sufficient conditions of the controllability and observability of the deterministic systems and the corresponding uncertain systems for the case of the uncertain optimal control system with application in capital asset management are considered., Advances in Systems Science and Applications, Выпуск 2 2021, Pages 8-19
