Photosensitive materials (x-ray films) are used to record the invisible x-ray image. It is required to reproduce all the characteristics of the invisible image in visible form .The films ability to do so depends on its sensitometric properties. Sensitometer: Measures films sensitivity to light; shows the range of densities on an image. Sensitometry:- The scientific study of the response of photosensitive material to different levels of exposure. How is it done? Producing a sensitometric strip

Aims: The materials aim to cover some of the MoE’s (Ministry of Education) learning outcomes such as familiarity and correct use of parts of speech‚ syllables etc. Poetry is a Ministry curriculum genre to be used both for passive analysis as well as a productive skill and teachers shy away from it for many reasons‚ which I will deal with later. Evans (2001) proposes poetry as a good medium for teaching creative writing‚ something parents and the MoE want but schools find hard to teach.

This can be done by the use of instructional materials. Instructional materials are meant to stimulate pupils’ interest in the classroom for meaningful learning to take place. They also afford the pupils the opportunity to make use of more of their senses in the process of learning experiences which are not available in the classroom or school environment‚ are “brought” to the classroom for pupils’ attention through the use of instructional materials. For example‚ the use of the map of the world

Chapter I Introduction A. Background of the Study Hollow blocks are one of the most used building materials in our time. Since hollow blocks weigh around 9-11 kg‚ it is a must for reinforcement steel to be placed into the gaps of the hollow blocks and/or to be built on a strong foundation in order to avoid settling or cracking. A higher capital is needed for a strong foundation that can hold the weight of standard concrete hollow blocks (esp. for high and large buildings). The heavier the hollow
