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

requested information about thermo-chromic material and how can be benefits to our company. Before I give description about above material I would like to thank you for giving me opportunity and give me enough time and source to search information about this new material. Thermochromism is the reversible change in the color of a compound when it is heated or cooled. Systematically investigated thermochromism was in 1971 at first time. The following 4 materials are used as thermochromism (1) Organic

certain underlying values that contribute to how they organize their ethical or ideological value system. It is related to a degree of behavioural freedom by human beings. They can guide a person on the basis of internally chosen options. Therefore‚ values imply the (conscious) prioritizing of different behavioural alternatives which are perceived to be possible for the individual. Values can apply to groups or individuals. I’ve seen that aspects of the Canadian and Bangladeshi culture differ. For instance

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

TYPES OF MAGNETIC MATERIALS Paramagnetic materials have a small‚ positive susceptibility to magnetic fields. These materials are slightly attracted by a magnetic field and the material does not retain the magnetic properties when the external field is removed. Paramagnetic properties are due to the presence of some unpaired electrons‚ and from the realignment of the electron paths caused by the external magnetic field. Paramagnetic materials include magnesium‚ molybdenum‚ lithium‚ and tantalum
