On a theorem of Posner for 3-prime near-rings with $(\sigma,\tau)$ derivation
The analog of Posner's theorem on the composition of two derivations in prime rings is proved for 3-prime near-rings with $d_1 a (\sigma,\tau)$-derivation and $d_2$ a derivation.
Identifying block rotations from remanent magnetization effect: Example from northern Central Turkey
(Springer Berlin, 2007)
One of the difficulties in interpreting magnetic anomaly data is the distortion caused by rock body magnetization. There have been several successful studies carried out on the estimation of body magnetization based on the ...
Color change evaluation of denture soft lining materials in coffee and tea
(JAPANESE SOC DENTAL MATERIALS DEVICES, 2007)
This study evaluated the color stability of soft denture liners after being exposed to coffee and tea solutions for different time periods. Four soft denture liners and a denture base polymer were tested. Five specimens ...
Effects of acute and chronic cooling on cardiorespiratory depression in rodents
(PHYSIOLOGICAL SOCIETY JAPAN, 2007)
The cardiovascular and ventilatory responses of the Wistar rat (a nonhibernator) and the Syrian hamster (a hibernator) to acute and chronic cold exposure were investigated. The acute lowering of core temperature (T-c = 22 ...

Crystal and molecular structure of N-Trityl-m-aminophenol chloroform solvate
(Japan Society for Analytical Chemistry, 2007)
The title compound, (C26H23N)3·CHCl3, was synthesized by the reaction of trityl bromide with m-toluidine in chloroform and crystalized in the trigonal R3 space group (Z = 6) with the one molecule of chloroform, and with a ...
A safe and effective method for treatment of chronic subdural haematoma
(CANADIAN J NEUROL SCI INC, 2007)
Objective: Burr-hole irrigation and burr-hole drainage without irrigation are the most popular methods for treatment of chronic subdural haematoma. It is not well known if irrigation is necessary or which method has a ...
