Earthing Single point earths

This Primal Matter is commonly called Sulphur and Quicksilver. Raymond Lully, (Codicit. c.9,) calls them the two extremes of the STONE and of all the metals. Others say, in general, that the sun is its father and the moon its mother that it is male and female that it is composed of four, of three, of two and of one 5 and all this to conceal it. It is found everywhere on the earth, on the sea, on the plains, on the mountains, etc. The same author who says that their Matter is unique, says also that the STONE is composed of several individual principles. All these contradictions are only apparent, because they do not speak of Matter from a single point of view but in regard to its general principles, or to the different states in which it is found in its operations. 

Where an intrinsically safe circuit is earthed by construction at the place of the field device (e.g. this is frequently the case using thermocouples), an Ex i-isolator with galvanic isolation shall be inserted. The reason is that intrinsically safe circuits shall be earthed at one single point only. 

Intrinsically safe circuits may be isolated from earth or connected to the equipotential bonding system at one single point, if this system covers the total installation area of the intrinsically safe circuits. 

Salt-inclusion solids described herein were synthesized at high temperature (>500°C) in the presence of reactive alkali and alkaline-earth metal halide salt media. For single crystal growth, an extra amount of molten salt is used, typically 3 5 times by weight of oxides. The reaction mixtures were placed in a carbon-coated silica ampoule, which was then sealed under vacuum. The reaction temperature was typically set at 100-150 °C above the melting point of employed salt. As shown in the schematic drawing in Fig. 16.2, the corresponding metal oxides were first dissolved conceivably via decomposition because of cor-... 

To obtain some idea as to the actual vertical penetration of TCDD in those areas contaminated by dispersion, three sample points were selected near the farm road which was sprayed in 1971. At each point a single sample was collected from each of three depths, viz, at the 0- to 2-, 2- to 4-, and 4- to 6-inch depths, using clean knives and spoons. The selection of a 2-inch increment was based upon the estimated removal on a single pass by a qualified operator of earth-moving machinery. The resulting data are as follows ... 

In a paper by Fisk and Remeika (1989) several points concerning the growth of single crystals from metal fluxes have been discussed. Attention has been dedicated to various aspects of the problem of separating crystal and flux, for which two main approaches, chemical and mechanical, may be considered. The following examples drawn from the preparative chemistry of the rare earth alloys were described. 

Tlhe Sedan thermonuclear detonation in July 1962 created the largest A man-made crater ever produced by a single explosive. Approximately 7.6 million tons of earth were moved by this detonation to produce a crater with a radius of 608 feet and a depth of 323 feet (9). Fifty-eight percent of the crater mass or 4.8 million tons of desert alluvium were ejected from the crater during the detonation and distributed somewhat symmetrically around the ground zero point to a distance of 6000-7000 feet (1). 

Periodically, science moves to a point where a wide range of observations can be explained by a single comprehensive idea that has stood up to repeated scrutiny. Such an idea is wbat scientists call a theory. Biologists, for instance, speak of the theory of natural selection and use it to explain both the unity and the diversity of life. Physicists speak of the theory of relativity and use it to explain how we are held to Earth by gravity. Chemists speak of the theory ofthe atom and use it to explain how one material can transform into another. 

Amide. — It has been pointed out before that europium behaves more or less like the alkaline earths and is closely related to strontium and barium. It is found to react with liquid ammonia at —78° C in much the same way as the alkali metals forming a characteristic deep blue solution. Eu(NH2)2 can be isolated [260] from the blue solution. Recent electron paramagnetic studies [261] of solutions of europium in liquid ammonia showed the presence of complex hyperfine lines arising from Eu2+ (8 7/2, g — 1.990 0.002) besides the characteristic single line of the solvated electron (g = 2.0014 0.0002) K The departure of the Eu2+ <7-value from the free electron value is explained as being due to spin-orbit coupling and a slight admixture (3.5%) of the 6P7/2 state. 

An application has been found in which a system that exhibits an upper, or lower, critical consolute point, UCST or LCST, respectively, is utilized. At a temperature above or below this point, the system is one homogeneous liquid phase and below or above it, at suitable compositions, it splits into two immiscible liquids, between which a solute may distribute. Such a system is, for instance, the propylene carbonate - water one at 25°C the aqueous phase contains a mole fraction of 0.036 propylene carbonate and the organic phase a mole fraction of 0.34 of water. The UCST of the system is 73 °C (Murata, Yokoyama and Ikeda 1972), and above this temperature the system coalesces into a single liquid. Temperature cycling can be used in order to affect the distribution of the solutes e.g. alkaline earth metal salts or transition metal chelates with 2-thenoyl trifluoroacetone (Murata, Yokayama and Ikeda 1972). 

All scientists agree that chemistry is the basis of life and with that preamble it seems almost certain that the first cells one sees in the Hadean stones are the first ones on earth their ancestors were the heat- and light-driven bio-reactors. The Darwinians see the same cells but because the (in principle unprovable) single origin is a creed of the model, they postulate that a single ancestor must have lived much earlier and mutated into all of the cells that are visible at this horizon. At this point the old hypothesis is defeated by the researchers in planetary sciences who do not see any biology-time before the time of the first massive invasion of the earth crust by cells. The hell fire of global accretion was too close for descent with variation .
