Research work principally of Von Neumann; Richard Courant et. al established firmly the use of finite -difference techniques for the solution of linear partial differential equations

This thesis serves a dual purpose. First, a method is presented which simplifies the integration of the governing steady stage equations of an incomprehensible viscous fluid with vanishing body and inertia forces. The ...

This thesis is written in two parts. part one examines the environmental setting and the theoretical background to the evolution of the landforms in the coastal zones of Lagos, as well as characteristics of the geomorphological ...

bacterial counts of samples of freshly caught shrimps, Penaeus duorarum and ofm sea water from Nigeria, were carrioed out for a period ofm ten months, from April 1975 to january 1976. A monthly variation in the size of the ...

1-bromo-3methylbut-1-yn-3-ol, 1-bromo-3-methylpent-1-yn-3-ol, 4-hydroxy-4-methylhex-2-tn-nitrile, 1-chloro-3-methylpent-1-yn-3-ol, 4-methyl-2, 3-dienenitrile and 4-methjolxy-2-yn were separately prepared and then, each of ...

The fungi isolated from Lagos lagoon and decomposing sawdust in the lagoon included Aspergillus flavus, Aspergillus fumigatus, Asperghillus gigateus, Aspergillus niger, Aspergillus tamarii, Candida famata, Cladosporium ...

Four micro-organisms were isolated from rotted onion bulbs, purple variety, purchased from markets in the Lagos State of Nigeria. Three of them were pathogenic; they produce soft rot when wound-inoculated into healthy ...

The catfish, Chrysichthys nigrodigitatus (Lacépède) is widely distributed in Nigeria. Because of its growing importance in fish-farming and its abundance in both fresh and brackish water in Nigeria, some aspects of its ...

Aspects of the biology of Ilisha Africana (Bloch) caught off the Nigerian Coast were studied. These included the taxonomy, distribution, age and growth, food and feeding habits, reproduction and racial studies. The use of ...

The quest for the improvement in students’ performance based upon their learning efforts in chemistry has continued unabated. This quest has led to the uncovering of new needs which can ameliorate both the teaching and ...

Rhizosphere studies of two local green vegetables, celosia aregentea Linn and Hibiscus esculentus Linn (new name Abelmoschus esculentus) were studies from vegetative stage to senescence. The viable seeds beds made from ...

This study was designed to investigate the teacher's role perception and the expectation of this role by the teacher and his reference groups in selected secondary schools in Ondo State. A Questionnaire called STRES probed ...

The kinetics and mechanisms of the reactions of nitro-activated diphenul ethers with substituted anilines in benzene have been investigated. The reactions except that of 2, 6-dinitro phenyl 2,4,6-trinitrophenyl ether are ...

Species composition and seasonal changes in the Phytoplankton of Lagoon and adjacent sea from November 1980 to October 1982 were investigated in relation to environmental factors. The physico-chemical parameters exhibited ...

Aspects of the biology of the ten-pounder Elops Lacerta (Val) in the freshwater, brackish and marine habitats were investigated. The investigations covered the taxonomy, racial study, distribution, age and growth, food and ...

The study revealed that there was a quantitative recruitment in colonies of Amitermes evuncifer, whenever food was discovered by the scouting foragers. Discovered food stimulated the termites to accelerate their running ...

Studies in the synthesis of long chain compounds. This thesis is in two parts. Part 1 involves a study of the straight chain alkanes containing many carbon atoms. These are important analogues of polyethylene, a versatile ...

This thesis discusses the development, design, fabrication and testing of spectrally selective beamspliting absorption filters (AF-SSBS) which can decouple quantum and thermal convertors to improve conversion of the total ...

Transport metabolism of adenosine have been studied in Trypanosoma vivax. In the transport studies, it was found that adenosine uptake was inhibited by different antimetabolites. Phlorizin, coformycin and formycin A produced ...

Oral contraceptive agents (OCA) have been in use for well over two decades with a total of 150 to 200 million women all over the world using the pills as means of birth control. Aside from their gynecologic influences, the ...
