Back Filling Technique at Kushiro Colliery.

Piggy-back microtransfer technique.

A new microtransfer technique is described which uses a modified, V-bottom, disposable, 96-cup plastic plate that permits serial dilutions and direct rapid transfer to a recipient micro cell culture plate.

Email Classification Using Back Propagation Technique

This paper proposes a new email classification model using a teaching process of multi-layer neural network to implement back propagation technique. Email has become one of the fastest and most efficient forms of communication. However, the increase of email users with high volume of email messages could lead to un-structured mail boxes, email congestion, email overload, unprioritised email mes...

A simplified technique for ICA back pressures.

Looking back at smallpox.

Smallpox apparently arose through transfer of variola virus to humans from another animal species. By causing a brief infection that required close contact for transmission and engendered solid immunity, the agent was always vulnerable to simple isolation measures. The high replicative fidelity of the viral DNA polymerase limited variola's ability to adapt to humans and preserved orthopoxviral ...

Fabrication of Miniaturized Variable-focus Lens Using Liquid Filling Technique

This paper describes a simple method for fabricating a variable-focus lens by using PDMS (polydimethylsiloxane) and filling with liquid for the variable-focus lens. The lens diameter of 2-mm was designed in this experiment and expected to reach the focal length in the range of 3 ~ 12 mm. The theoretical value between the liquid volume and the lens contact angle at different focal lengths were s...
