Optogenetics is a
booming multidisciplinary bioengineering technology. It has the characteristic
of high spatial-temporal resolution and cell-type specific. It overcomes the
disadvantages of traditional methods of the activity control for the cell and
organism, and also provides a revolutionary method for the research of
neuroscience. The research fields include fundamental research of neural
circuit, study and memory research, habituation research, dyskinesia, sleep
disorders, parkinsonism, depressive disorder, anxiety disorder etc., and many classic
laboratory animal germ line (drosophila melanogaster, nemathelminth, mice,
Marmoset, and machin etc.)

Neuroscience is the scientific study of the nervous system. It is
currently an interdisciplinary science that collaborates with other fields such
as chemistry, computer science, engineering, linguistics, mathematics,
medicine, genetics, and allied disciplines including philosophy, physics, and
psychology. It also exerts influence on other fields, such as neuroinduction
and neurology. The scope of neuroscience has broadened to include different
approaches used to study the molecular, cellular, developmental, structural,
functional, evolutionary, computational, and medical aspects of the nervous
system.

What is the principle for determining the number of blastholes in a tunneling face?
The number of blastholes is mainly determined by the section of the shaft, the nature of the rock, and the amount of charge per cycle.
So far, the formula that is commonly used for everyone to make estimates and propose design basis is an empirical formula and an analytical formula:
   First, the empirical formula
In the formula:
N - the number of blastholes required for each tunneling cycle;
F-rock solidity factor;
The cross-sectional area of ​​the S-well lane, m 2 .
   Second, the analysis formula
N=qShη/ɑg
In the formula:
Cross-sectional area of ​​S-wellway, m 2 ;
H-the average charge length of each blasthole, mm;
Η-blasting utilization factor should be 0.8~0.95;
â±-charge coefficient, the ratio of charge length to blasthole depth, æŽ É‘ 0.6 = 0.6 ~ 0.8, auxiliary eye É‘ = 0.5 ~ 0.7;
G-the average charge of each blasthole, kg;
Q-explosive unit consumption, kg/m 3 .
In the above formula, the blastholes are distributed substantially evenly according to the amount of explosive required for each tunneling cycle.
