Essays on Gamma

The article under consideration is “Radiation technologies: past, present and future” by A.G. Chmielewski and M. Haji-Saeid (2004). The research in question is devoted to the problem of radiation and its sources. The authors dwell on the historic background of studying the issue as well as on more recent findings in the sphere. X-rays and natural radioactivity were discovered as early as in the XIXth century. Very soon after that, Marie Curie-Sklodowska and her husband proved the action of radioactivity on living organism and materials. Since that time the study of radiation effect has not stopped. Nuclear reactors producing ...

Summary

Supported on carbon particles using the high energy electron beam Yuji Ohkubo, Masashi Shibata, Satoru Kageyama, Satoshi Seino, Takashi Nakagawa,Junichiro Kugai, Takao A. Yamamoto (2011) in their study of the Radiation-induced synthesis of Au–Pd nanoparticles of random alloy structure supported on carbon particles using the high energy electron beam found that Au-pd particle of ca 5-nm dispersed well on the carbon surface with ca. 30-nm without a significant agglomeration. Upon adding citric acid to the original solution, the resulting high pH was effective in the formation of alloy structures from the resulting bimetallic nanoparticles. Using the irradiation ...

Net neutrality is a design paradigm that has been used in the United States to protect the internet users. It argues that the network providers should be detached entirely from the information they are sending to their clients. Therefore, at no point should a given web information be given priority over the other. The policy implies that information networks are more important and useful to their users when it gives no focus on one issue over the other. In addition, the neutral network can be designed without prodding into any legality. The Internet is an interconnection of computers, allowing ...

The Sun

The Sun is known as the only one star in the Solar system. It is the center, around which the planets, asteroids, satellites, comets, space dust are revolving. The nature of each planet depends on the distance that separates the planet from the Sun. This bright star is important for all the planets surrounding it. So, how much the humanity knows about the fiery star that can kill the entire earth in one second? Since the beginning of time, people looked at the sky, hoping to learn a little about the twinkling stars and the fiery sun. As we ...
