To run a circuit on PSpice, you must have at least one ground connection in your circuit. To ground your circuit, you must place a symbol called 0 (the number zero). There are three ways to place ground symbols ... 

The technique for staining thin sections is virtually identical, except the section is placed ground surface up in the HF vapor, and dipped in the various liquids, holding the section with forceps. After giving the section the final dip in distilled water, the excess amaranth is swept away with a gentle stream of compressed air, and the section is dried with warm air from a hair dryer. The cover glass can be mounted with epoxy resin (without hardener for possible easy removal later). Be aware that particles exposed on a thin-section surface will have parts below the level of the section and, therefore, will not show the stain. 

Employers may use insulating equipment other than a live-line tool for placing grounds on or removing grounds from circuits of 600 volts or less under certain conditions.

Aufbau principle In building up the electronic configuration of an atom or a molecule in its ground state, the electrons are placed in the orbitals in order of increasing energy. 

Let us now consider the case where tliere is more tlian one exciton in tlie given molecular ensemble. The presence of two or more excess excitons not only creates two or more holes in tlie ground state (see case (a) above) but it also opens up tlie possibility of two excitons being found on neighbouring molecules. Then tlie following two-stage process can take place [26] ... 

There are two mechanisms by which a phase change on the ground-state surface can take place. One, the orbital overlap mechanism, was extensively discussed by both MO [55] and VB [47] formulations, and involves the creation of a negative overlap between two adjacent atomic orbitals during the reaction (or an odd number of negative overlaps). This case was temied a phase dislocation by other workers [43,45,46]. A reaction in which this happens is... 

The distillation heads Fig. 22(F) and Fig. 22(G) can be fitted with thermometers having a ground-glass cone just above the bulb (Fig. 22(M)). These are expensive, and it is usually more convenient to fit a thermometer pocket (Fig. 22(N)) which consists of a small well , fitting as shown into the neck of the flask. A small volume of mercury is placed in the well just to cover the bulb of a conventional thermometer, and thus provides excellent thermal contact between the thermometer and the sides of the pocket.
