Aiming at the current situation of lack of environment and equipment in radar Wall Clock training, a radar operation training method based on the combination of virtual and real is proposed.Firstly, the connotation of the concept of virtual-real combination is analyzed.Secondly, the interaction methods of combining physical radar and virtual enviro
A comparison of the cellular content of needle tip aspirates and entry sites after transconjunctival intravitreal injection (IVI) using different needle types was performed.White outbred rats and human cadaver eyes were used for IVI by hypodermic 27 gauge (G) and 30G needles, and spinal anesthesia Pencan 27G needles.Aspiration of vitreous for quant
Abstract Background In causal analyses, some third factor may distort the relationship between the exposure and the outcome variables under study, which gives spurious results.In this case, treatment groups and control groups that receive ARGAN OIL and do not receive the exposure are different from one another in some other essential variables, cal
We study the singularities of Legendrian subvarieties of contact manifolds in the complex-analytic category and prove two rigidity results.The first one is that Legendrian singularities with reduced tangent cones are contactomorphically biholomorphic Styling cream to their tangent cones.This result is partly motivated by a problem on Fano contact m
The storage of natural gas in geological structures such as depleted fields, aquifers and salt caverns plays an important role in a gas supply system as it balances the fluctuation of gas demand and price.Hydraulic loss due to fluid flow through gas storage production equipment and an interfering effect from nonequal productivity index of storage S
