This paper presents the issues of technical state of subsurface structures in operation and the erection of buildings under available development.It is stated that detailed monitoring of apac1/60/1/cw technical state of underground tunnels is essential, since the structure is unique and technologically complex.The aspects of geotechnical monitoring

The physical properties of porous silicon (PSi) can be adjusted to provide a better performance in optoelectronic devices.A controlled method commonly used to fabricate PSi is the anodization process, which employs platinum as a conventional cathode.Herein, we investigate the effect of replacing the Pt cathode with symmetric heavily doped silicon o

It has been 10 years since the seminal work of Dwight Bergles and collaborators demonstrated that NG2 (nerve/glial antigen 2)-expressing oligodendrocyte progenitor cells (NG2 cells) receive functional glutamatergic synapses from neurons ( Bergles et al., 2000 ), contradicting the old dogma that only neurons possess the complex and specialized molec
