May it Please Your Honor : Letters of Petition as Historical Evidence in an African Colonial Context

This paper presents some preliminary conclusions drawn from an ongoing project which aims to collect and collate letters of petitions in colonial Nigeria as primary source for historians and other scholars. The goal is to show the potential use of petitions as a foundation for gauging African reactions and responses to colonialism focusing on the petitions that emerged during the Second World War in colonial Eastern Nigeria. The paper is based on the collection of petitions located at the National Archives of Nigeria at Enugu written by people living in the rural and urban areas in colonial Eastern Nigeria during the Second World War. Mainly addressed to District Officers in Colonial Eastern Nigeria from within the region, they reflect the concerns of individuals and groups as they relate to the crisis engendered by the Second World War and the policies and controls imposed by officials to bolster the British war effort

Comparison of two- and three-dimensional flow computations with laser anemometer measurements in a transonic compressor rotor

Two and three dimensional inviscid solutions for the flow in a transonic axial compressor rotor at design speed are compared with probe and laser anemometers measurements at near-stall and maximum-flow operating points. Experimental details of the laser anemometer system and computational details of the two dimensional axisymmetric code and three dimensional Euler code are described. Comparisons are made between relative Mach number and flow angle contours, shock location, and shock strength. A procedure for using an efficient axisymmetric code to generate downstream pressure input for computationally expensive Euler codes is discussed. A film supplement shows the calculations of the two operating points with the time-marching Euler code

Biafra and the Discourse on the Igbo Genocide

There has been a reluctance or indifference to a systematic study and documentation of the Igbo Genocide in Nigeria. In the main, the reason has been due to official and non-official attempts to subvert a focus on an event in which more than one million Igbo were slaughtered through a process that was fomented, orchestrated, executed, and supervised by the Nigerian state

Agriculture, Environment, and Sustainable Development in Nigeria

Agriculture is the most critical economic activity in every society. It has historically remained the source of food that sustains the population and a source of wealth accumulation. This chapter looks at the intersection of environment, agriculture, and sustainable development. Whether it be crop production or animal husbandry, suitable agricultural production is dependent on a suitable and sustainable environment. This article looks at the link between the environment, agricultural productivity, and sustainable development. It also examines the link between contemporary agricultural crisis and environmental crisis and how both issues have posed a challenge to continued and future suitable, sustainable development
