Paper Why renewable power sources are better than nuclear power? Nuclear power is the most productive power source. However‚ there are several ongoing debates around the efficiency and the usage of nuclear power. Several factors such as the catastrophes in Chernobyl and Fukushima and the depleting of coal and gas reserves have led to the idea behind the renewable power sources. The renewable power sources are the future of the energy production in the world. Renewable energy is the energy

The Iron-Carbon Diagram There are two iron-carbon equilibrium diagrams: - stable iron-graphite Fe-Gr - metastable iron-cementite Fe-Fe3C The stable condition usually takes a very long time to develop. The metastable diagram is of more interest. Fe3C iron carbide called cementite because it is hard. Following phases exist on Fe-Fe3C diagram: - liquid solution of iron and carbon (L) - ferrite ( ) – an interstitial solid solution of carbon in Fe (bcc). At room temperature ferrite is ductile but

With the kingship diagram‚ I am focusing on my matrilineal descent. Kingship is a word use by anthropologists to describe certain family relationships; while a kingship diagram is basically a family tree. Fictive kin members bring character and different cultural beliefs into the family.

Sometimes it is good to have

in mathematics. Developed at the end of the 19th century‚ set theory is now a ubiquitous part of mathematics‚ and can be used as a foundation from which nearly all of mathematics can be derived. In mathematics education‚ elementary topics such as Venn diagrams are taught at a young age‚ while more advanced concepts are taught as part of a university degree. A set is a well defined collection of objects. Georg Cantor‚ the founder of set theory. A set is a gathering together into a whole of definite‚ distinct
