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

INTRODUCTION 1.1. BACKGROUND TO THE STUDY Social Studies can be defined as a discipline in which we can learn about our world and man’s interaction with his immediate and remote environment. Since Social Studies deals with how men interact with its social and physical environments‚ how can this interaction of physical and social environment be learnt by the pupils? This can be learnt in the classroom where teaching and learning cannot be conducted by the teacher by merely feeling his pupils with facts

Composite materials A composite material consists of two or more physically and/or chemically distinct‚ suitably arranged or distributed phases‚ with an interface separating them. It has characteristics that are not depicted by any of the components in isolation Most commonly‚ composite materials have a bulk phase‚ which is continuous‚ called the matrix‚ and one dispersed‚ non-continuous‚ phase called the reinforcement‚ which is usually harder and stronger. The arrangement of the fiber in the matrix

Lecture based on Materials (Book: The science of strong materials‚ Penguin Publishers.) The aeronautical journal (Library can order for you)‚ one article written in 1996‚ by Peal‚ I.J.Mocolm. Ceramic Science‚ pg 123-131. (Relevant to exam) There are two key reasons for using thermoplastic composites: * save time & handling costs in production * eliminate labour-intensive riveting & bonding * can produce large profile sections that are some 20 % lighter than metal &

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.

28 Oct‚ 2013 Material Wealth over Emotional Health Snow white has many different versions of it written‚ most of which display a great story of a young girls development. Although each tale is based upon the same topic‚ the process by which the girl learns and develops varies from each tail. As in Lasair Ghueg‚ The King of Ireland ’s Daughter‚ the young girl has a distant relationship to her parents and is constantly colliding with her step mom. Many younger kids and even adults are in this same

Composite Materials A composite is a combination of two or more materials bonded together to gain some overall necessary goods. Types of composite include: laminated materials fibre composites particle composites. A laminate contains thin pieces of material fused together. Common examples are plywood and car windscreens. Wood is durable when exposed to a ductile force equivalent to its grain‚ but if the strength is across the particle it splits simply. A windscreen is made in a parallel way; two
