Matter origin

A general principle is governing the relation between physical parameters and underlying distribution functions. Its paramount importance in the field of soft condensed matter originates from the importance of polydispersity in this field. Let us recall the principle by resorting to a very basic example molecular mass distributions of polymers and the related characteristic parameters. [Pg.21]

J. J. Thomson (Moore 1912, 72). But he pushed the new physics in distinctly occult directions that those physicists would have rejected Science is beginning to regard matter as a form of energy and our observations of the human mind, thought impulses, show evidence in favour of energy being a form of mind. Thus it would appear that matter originated indirectly from mind (75). [Pg.216]

By trapping the sediment from used alpine waters, reservoirs reduce the transport of suspended load to residual flow reaches. In these sections with a reduced channel flow, the tractive force and shear stress is drastically reduced. This additionally reduces the bed load transport, which may then result in solid matter originating from unaffected tributary streams remaiiung in the main channel, thus significantly increasing the debris-flow hazard for episodic high water discharge [36]. [Pg.83]

Terrestrial Detritus. Variability in ecosystem response to fertilization may be attributed in part to the interaction of aquatic and terrestrial ecosystems. In contrast to the many aquatic ecosystems in which higher trophic levels are fueled almost entirely by organic matter originating in the water column, other systems are driven by inputs of particulate and dissolved organic matter from land. The importance of this land-water interaction in regulating system metabolism has been obvious to stream ecologists for some... [Pg.100]

Several formulas have been proposed for calculating the amount of mineral matter originally in the coal using data from ashing techniques as the basis of the calculations. Of these formulas, two have survived and have been used regularly to assess the proportion of mineral matter in coal the Parr formula and the... [Pg.55]

It is therefore impossible to determine accurately the composition of the pure coal substance from the usual ultimate analysis simply by making allowance for the quantity of ash left behind as a residue when the coal is burned. Results obtained in this fashion are, as a consequence, quoted as being on a dry, ash-free basis, and no claim is therefore made that these results do in fact represent the composition of the pure coal substance. If, however, it were possible to calculate accurately the quantity of mineral matter originally present in the coal sample, then by making due allowance for this material, the composition of the pure coal material could be deduced with reasonable precision and certainly with a greater accuracy than could be obtained by adopting the analytical figures calculated to a dry, ash-free basis. [Pg.96]

The matter left over is something bounded by determined dimensions. In itself it does not have any specific dimensions, but it is capable of receiving them, i.e. capable of being marked off into determinate sizes. This implies that matter already has extension in itself. The powers of hot and cold, fluid and solid modify the state of matter, but they do not extend matter originally.3... [Pg.100]

The conscious final decision to take the risk, with the current sequence, should be read as a personal conviction that the beauty of chemistry can never be fully appreciated unless viewed against the background in which all matter originates - space-time, or the vacuum. Not only matter, but all modes of interaction are shaped by the geometry of space, which at the moment remains a matter of conjecture. However, the theory of general relativity points the way by firmly demonstrating that the known material world can only exist in curved space-time. The theory of special relativity affirms that space-time has a minimum of four dimensions. Again, spaces of more dimensions are conjectural at present. [Pg.10]

Speciation analysis procedures are complicated because they examine a multitude of element forms that demonstrate different physicochemical properties in a broad variety of environmental materials, which are characterized by different states of matter, origin, and analyte content. [Pg.360]

Primary particulate matter originated from anthropogenic sources (both fine particulate matter with diameter below 2.5 pm, PM2.5, and the coarse fraction with diameter from 2.5 to 10 pm PM2,5 io)... [Pg.160]

The term, mineral matter , usually applies to all inorganic, noncarbonaceous material in the coal and includes those inorganic elements which may occur in organic combination. Physically, the inorganic matter can be divided into two groups—inherent mineral matter and extraneous mineral matter. Inherent mineral matter originates as part of the growing plant life from which coal was formed. Under the circumstances, it has a uniform distribution within the coal. Inherent mineral matter seldom exceeds 2 to 3 percent of the coal [12]. [Pg.356]

Another method (ASTM D-893) covers the determination of pentane-and toluene-insoluble constituents in used lubricating oils. Pentane-insoluble constituents include oil-insoluble materials, some oil-insoluble resinous matter originating from oil or additive degradation, or both. Toluene-insoluble constituents can come from external contamination, fuel carbon, highly carbonized materials from degradation of fuel, oil, and additives, or... [Pg.275]

In the near and the mid infrared, the absorption of light by matter originates from the interaction between the radiation from a light source and the chemical bonds of the sample. More precisely, if the atoms situated at the two extremes of a bond are different, they form an electric dipole that oscillates with a specific frequency. If such a non-symmetrical bond is irradiated by a monochromatic light source whose frequency is the same as the dipole, then an interaction will occur with the bond. Thus, the electrical component of the wave can transfer its energy to the bond on condition that the mechanical frequency of the bond and the electromagnetic frequency of the radiation are the same (Figure 10.1). This simplified approach can be used to rationalize that in the absence of a permanent... [Pg.207]
