Provided herein are processes for preparing caprolactam from a starting material such as one or more of the cis,cis-, cis,trans- and trans,trans-double-bond isomers of muconamide, muconic acid ester, or muconic acid. The starting material, intermediates, and caprolactam prepared therefrom can contain carbon atoms derived from biomass containing detectable C content determined according to ASTM D6866 and optionally containing a C content up to 0.0000000001% (one part per trillion). Caprolactam so prepared can be used to make various polyamides.

A circuit for measuring the internal impedance of the cell of a heart pacer in order that the remaining life of the cell can be estimated. The test is performed by cutting off all current flow from the cell to the pacer circuitry, the pacer still being powered, however, by the conventional by-pass capacitor. When the cell impedance test is conducted, a test capacitor is placed across the cell and it charges exponentially with a time constant which is a function of the cell impedance. By measuring the time required for the test capacitor potential to reach a reference level, the cell impedance can be ascertained. The measured parameter can be telemetered out of the pacer along with other data in the conventional manner. With a typical lithium iodide cell, the internal impedance of the cell varies from less than 100 ohms when new, to tens of kilohms near the end of the cell life.

In the capillary electrophoretic system, the components of a sample to be separated and detected are labelled by a radioactive material which emits gamma rays or beta particles with energy high enough to penetrate the electrolyte and the capillary tube. A semiconductor detector outside the tube and placed adjacent to the tube detects the gamma rays or beta particles in order to detect the presence of the components of the sample. A weaker radio-label may also be used in conjunction with scintillating material which is introduced together with the sample into the tube or through a different tube. Alternatively, the scintillating material may be placed inside the tube or made a part of the tube. The scintillating material emits light in response to radiation from the radio labels on the components of the sample to enable detection of the component. The power supply for driving the electrolyte in the tube is controlled by a control system in response to the detector signal to reduce the voltage, turn the power supply off or apply a voltage of opposite polarity in order to increase the residence time of a particular component which has been detected or to make it pass the detector region two or more times.
