Base elements

Since the majority of the elements in surface dust arise from deposited aerosol and added soil it is not surprising to find strong linear relationships between the concentrations of the elements in an atmospheric dust and street or house dust. This is illustrated by the two examples given in Fig. 8 for remote house dust vs urban atmospheric dust and street dust vs rural atmospheric dust. As discussed above crustal/soil material is a major component of atmospheric dust and the soil based elements in the atmospheric dust are Al, Ca, Fe, Mg, Mn, Ni, K, Si and Ti. The elements As, Br, Cd, Cl, Co, Cu, Pb, Rb, Se, V, and Zn are, on the other hand, enriched in atmospheric dust. The same elemental distribution applies to surface dust, but in this case their concentrations (compared on a mass basis) are reduced presumably due to dilution with soil. However, the elements enriched in the atmosphere remain enriched in the surface dusts.

Fuze, Spitback or Fuze, Flashback. A fuze located in the forward part of a shaped charge munition. When initiated by impact it produces a detonation which is directed toward the element located in the base of munition and this, in turn, detonates the main explosive charge. The combination of point impact fuze and base element is referred to as point initiating base detonating" (PIBD) fuzing system...

The dominant elements in marine DOM are expected to be C, H, and O, with lesser quantities of N, S, and R Concentrations of organic C, N, and P can be measured directly on seawater without isolating DOM, using methods that were described in Section 11.1.2, and those concentrations can be used to calculate molar ratios of C/N, C/P, and N/P Concentrations of organic C, N, and P cannot be converted into conventional mass-based elemental compositions (%C, %N, and %P), because the total mass of DOM cannot itself be measured directly in seawater. To be able to calculate the mass percentages of all major elements in marine DOM, samples must be isolated and purified to yield dry, low-ash materials. 

All classical pseudohalogens can be deduced in this way. A base element and paraelement have the same number of valence electrons. This means that covalent electron pairs held in common by base atom and ligand are assigned to the base atom, which becomes electronically isovalent with the reference element. 

There is an alternative oxidant for secondary alcohols that is just as efflcientand much safer from an environmental standpoint 5.25% (0.75 M) sodium hypochlorite solution available in the grocery store as household bleach. The mechanism of the reaction is not clear. It is not a free radical reaction the reaction is much faster in acid than in base elemental chlorine is presumably the oxidant and hypochlorous acid must be present. It may form an intermediate alkyl hypochlorite ester, which, by an Ej elimination, gives the ketone and chloride ion. 

Several carriers/extractants/ligands are available commercially for the extraction of acids, bases, elements such as copper, cobalt, nickel, zinc, iron, chromium, precious metals, and the rare earths. The physicochemical properties of the various commercial extractants available for type 2 facilitation have been previously reported by Gu et al. [46] and Cox [91], and the chemical behavior of these extractants can be broadly classified into three categories ... 

The success in the development of CNT-based elements for nanoelectronics can be achieved when one is able to produce CNT with controllable properties, deposit them on different surfaces and manipulate along the substrate towards the desirable electrode pair with the proper control of the electric contact between CNT and electrodes. We have fabricated samples of nanovaristors and nanotransistors [4] based on CNT and carbon stripes. Their electric behavior has been studied at high temperatures (up to 125°C) and radiation fields up to 1.1610 rad. CNT based transistors can be applied in high sensitive miniaturized...

Then I journeyed with the Jew to Venice. There he sold to a Turkish merchant forty pounds of this Silver. While he was haggling with the merchant I took six Loth of the Silver, and brought it to a Goldsmith, who spoke Latin, and kept two journeymen, and I asked him to test the Silver. He directed me to an Assayer on Saint Marks Place, who was portly and wealthy. He had three German Assay-assistants. They soon brought the Silver to the test with strong acids, and refined it on the Cupel [a porous cup used to separate precious metals from base elements] but it did not...
