A system for controlling operation of at least one machine at a worksite includes controls operable under the control of a first entity to operate a first machine to perform one or more tasks at the worksite. An input voltage for the power supplies powers, and is monitored by, a first control unit having outputs for enabling the power supplies. Additionally, aspects of the present disclosure relate to the management of intra-small cell communication in accordance with communication networks implementing multiple small cells. Each delay circuit provides a programmable delay to the delayed clock signal to generate a unique delayed clock signal used to clock an output signal into the respective output buffer. The light-emitting device has a light-emitting layer existing between first and second electrodes and a field effect transistor, of which the active layer is an amorphous. The present disclosure also relates to a process for making up and caring for keratinous substances, such as the skin, comprising the application of the composition to the keratinous substances.
