Firing is a crucial step in the production of pottery, as it irreversibly transforms clay into ceramic. Clay sintering and subsequent vitrification occur during firing, together with other transformations undergone by specific minerals rock inclusions according to their optical physical properties, including colour. Some these are visible thin-sections might be interpreted technological markers...

Abstract The barrel is one of the important parts artillery. At same time, when firing, bore needs to withstand high temperature and pressure powder gas as well impact friction projectile, different damage forms such cracks, wear dechromium on will appear. However, main reasons for error firing accuracy, it can even cause other security risks. In this paper, common formation force tube body dur...

In in vivo extracellular recordings from anesthetized adult rats, midbrain dopaminergic neurons fire spontaneously at low rates, averaging around 4 spikes/second (Bunney et al., 1973; Guyenet and Aghajanian, 1978; Deniau et al., 1978; Tepper et al., 1982). Under these conditions, the neurons exhibit 3 distinct patterns or modes of firing. The first is that of pacemaker-like firing, characterize...

Several recent studies have shown that hippocampal neurons fire during the delay period in between trials and that these firing patterns differ when different behaviors are required, suggesting that the neuronal responses may be involved in maintaining the memories needed for the upcoming trial. In particular, one study found that hippocampal neurons reliably fired at particular times, referred...

variety of energy–ecology optimizing means that optimum result of fuel combustion is focused not only on the direct efficiency of its usage but also on minimum environmental damage. best possible fuel combustion connected with controlled level of chemical underburn is considered to be one of the simpliest, cheapest and the most effective methods of optimizing. it is essential to notice that the...
