Introduction

Numerous types of color processes in film has been witnessed throughout time. It is evident that some color has been more successful in film than others. As a matter of fact, some colors have remained dominant for an extended period while others fade away quickly if not required. In the future, the film industry will go ahead to experience advanced technology that will enable filmmakers to use more attractive and sophisticated colors. Probably an essential point to remember is that the evolution in film has been undergoing a gradual transformation since time immemorial. Like a century ago, people thought ...

Explosives are a rather young industry. Despite the stereotype of it being primarily used for military purposes, it has come to be applied in a variety of fields. It stand to reason that explosives have given belligerent parties a strategic advantage on the battlefield, yet their application is well documented in areas other than the military industrial complex. It is quite difficult to envision the peaceful demolition of decrepit structures that are up for destruction due to the degrading state of the framework. The extractive industry is dependent on explosives inasmuch as mineworkers need their way cleared or portions of rock splintered. ...

How does the presence of ionic material affect a CMC? Amphiphilic surfactants have both polar and non-polar parts in their molecules. Whenever their concentration surpasses the crtitcal micelle concentration (CMC), surfactants molecules organize themselves in a special structures and form micelles. Micelles in aqueous environment are organized in the way that charged hydrophilic ‘head’ groups of surfactant molecules closer to the surface of a micelle and exposed to water. Whereas, hydrophobic ‘tails’ are directed inside a micelle to avoid contact with water molecules. There is electrostatic repulsion between charged head groups of the surfactant molecules. Therefore, the molecules tend to form a structure ...

According to Lexus.us, Dosimetry is defined as “Measurement of radiation exposure, especially X-rays or gamma rays; calculation of radiation dose from internally administered radionuclides”. (2010). Neutron dosimetry is neither as precise nor as complex as gamma dosimetry. In the United States today, neutron dosimetry is among the vital requirements used to carry out comparison of the clinical results gotten from radiotherapy trials done at the fast neutron therapy facilities. The neutron dosimetry radiation uses specialized devices which includes superheated drop detectors. Gamma rays originating from the surroundings, the phantom or biological object experiencing the radiation, the collimating or ...
