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

Site Planning and building form are very important from the point of view of seismic performance of the structure. Also it is very important to have proper compatibility of elements resisting seismic forces. Site Planning and selection of building forms is the first step in designing of any structure and the decisions taken are very crucial for the behaviour of those structures during any earthquake. Based on examples taken from various past earthquakes and theories this chapter gives guidelines

vs. Altima The cars my dad own are a 2015 Honda Accord and a 2016 Nissan Altima. Both cars share some basic features‚ but there are some marked differences that definitely give preference to one over the other. Economy is the major difference between them‚ but in comparing the two models‚ I have also considered safety features‚ and no less important‚ aesthetic. Economy is a very important point‚ because we all want to get the most of our money. The Honda Accord is a V4 and gives me 30 miles per gallon

SMART MATERIALS 1. Introduction The primary characteristic of a ‘‘smart material’’ is that it has the ability to respond to external stimuli in a technically useful and technically controlled way. The words ‘‘technically useful’’ and ‘‘technically controlled’’ are emphasized since all materials respond to external stimuli of some sort or other (as a simple example‚ all materials respond to temperature by changing their volume)‚ however‚ to be considered a ‘‘smart material’’ the response must
