Observations on acetylcholine

Intracellular observations on the disinhibitory action of acetylcholine in the hippocampus.

Abs~act-Intracellular recording (with KCI micr~lectrodes) from CA1 and CA3 hippocampal neurons in rats under urethane anaesthesia has revealed two kinds of facilitatory actions of acetylchofine (applied microiontophoretically). One was a mild depolarization (mean + 12 mV) accompanied by a rise in input resistance (mean + 14%). The reversal potential for this effect was much more negative than t...

Some Observations on Dirac Measure-Preserving Transformations and their Results

Dirac measure is an important measure in many related branches to mathematics. The current paper characterizes measure-preserving transformations between two Dirac measure spaces or a Dirac measure space and a probability measure space. Also, it studies isomorphic Dirac measure spaces, equivalence Dirac measure algebras, and conjugate of Dirac measure spaces. The equivalence classes of a Dirac ...

Multi-Observations Initial Orbit Determination based on Angle-Only Measurements

A new approach with the ability to use the multiple observations based on the least square approach has been proposed for initial orbit determination. This approach considers the Earth’s Oblateness by using the developed Lagrange coefficients. The efficiency of the proposed method has been tested in two scenarios. The first scenario is to use the simulated and the second one is to utilize the r...
