You may want to try v0.4.0.
To find a working git repository, you can run this command in the interactive bash:
$ git remote -v
and look for the remote (if there is one), then the branch name of the branch you want to try (e.g. master).
I had to edit the file gitconfig to make the file be tracked in the repo:
git config --global core.bare false
Don't forget to reload the configuration:
git config --global --unset-all core.bare
A structure is held in a down-hole pump in an electric power generation method of a high temperature superconductor having a critical temperature of 30 K or more. A superconductor of liquid nitrogen (at 77 K) or a cryogenic refrigerant is provided to a cooling unit for the cooling of a high temperature superconductor in the structure. The operating temperature of the high temperature superconductor is kept at 20 K or less by the cooling unit in the structure.
However, the electric power generation method of the high temperature superconductor by the above-mentioned electric power generation method has a problem that the cooling unit is always required to be operated even in a power off state. Therefore, it is inevitable that energy consumption is increased. Also, there is a problem that the costs are increased.
In order to solve the above-mentioned problem, there is a method in which a rare-earth metal such as Y or Tm, or an element of a 5f-electron orbital, is added as a nucleus to a metallic superconductor of the metal oxides (B. Leridon, Phys. Lett. A, Vol. 83, No. 3, pp. 285-288 (1981)). In this method, a nuclear structure is formed in a superconducting metallic phase, and the atomic number of the nucleus is preferably less than a number of electrons in the 5f-electron orbital. For example, when a nucleus of Yb is added to metallic superconductors of YBa2Cu3O7-x, metallic superconductors of NdBa2Cu3O7-x, or metallic superconductors of La2-xSrxCuO4-y, a nucleus of Yb is formed and YBa2Cu3O7-x, NdBa2Cu3O7-x, or La2-xSrxCuO4-y
