Continuity principle

Skip Hoists These hoists, which operate on a batch rather than continuous principle, are not so widely used as in the past. However, for high lifts and extremely lumpy or hot materials, the skip hoist is still an economical and practical device. 

Although only a few types of amino acids were available during the first few million years of the development of the code, it is likely that three-letter codes were used from the beginning. F. Crick also believes in a three-letter code, because of the continuity principle . It is possible that the third base had no function in the early days but was only necessary for steric reasons for example, because with a two-letter code (only two bases) in the mRNA strand, there would not have been enough room for two amino acid-bearing tRNA molecules. 

This was about the same time that Darwin himself thought of a naturalistic view of the origin of life remember his little warm pond full of salts and other good ingredients, which later on would become the famous prebiotic soup However, Darwin didn t think too much about the origin of life. Some of the contemporary scientists who popularized his views, however, did it for him, most notably Ernst Hackel, who stressed that there is no difference in quality between the inanimate and the animate world Anorgane and Organismen) and that therefore there is a natural and continuous flux from the one to the other (Hackel, 1866). This very continuity principle was also advocated clearly by Friedrich Rolle (Rolle, 1863 Fryer, 1880). 

Life originated from inanimate matter as a spontaneous and continous increase of molecular complexity. Chemical continuity principle - no transcendental principle. 

Modern melt-mixing machinery has all or most of the following functional capabilities depending on whether it operates using batch or continuous principles. 

A rather simple extension of the VB method by what is called the orbital-phase continuity principle does permit the qualitative judgment that cyclobutadiene should be less stable than benzene [see W. A. Goddard III, J. Amer. Chem. Soc. 94, 743 (1972), for applications to many processes for which VB theory generally has been regarded as incapable of giving much insight]. 

Hot-melt extrusion also requires other components to be scaled up in size as the extruder is scaled up in size. Typical components include multiple powder and liquid feeders, a chiller, a take-off cooling belt unit, and a control panel(s). Proper sizing of all components to achieve control of the process at each step is critical, especially because of the interrelationship of individual component feeds into the extruder and the resulting quality of the final extrudate. Variability on inputs translates into product variability on output from the extruder owing to its continuous principle of operation. 

The ensuing step is implementation of the mass continuity principle, which results in a material balance for both the solid and liquid phases within a defined control volume in the carbon bed. In its general form, the mass continuity equation is ... 

In an electrophoretic system, different zones can be present, where a zone is defined as a homogeneous solution separated by moving and/or stationary boundaries. We can apply the continuity principle (equation 8) to a boundary and derive the general form of the moving boundary equation. 

Rheology is part of continuum mechanics. Thus, the basic principles of continuity, homogeneity and isotropy are incorporated into the basic rheological relations. The continuity principle requires that there is no discontinuity of material properties from one mathematical point to another homogeneity demands that there is no concentration gradient, and isotropy imphes that the flow does not impose orientation on the flow elements. In multiphase systems that comprise polymer alloys and blends, these three principles are seldom obeyed [Utracki, 1995]. 

The mass balance has several other names, which are in wide use principle of conservation of mass, continuity equation, continuity principle, and material balance. They all mean exactly the same thing as mass balance, namely, that mass obeys the general balance equation, with no creation or destruction. 

Coal particle intramural gas migration accords with nonsteady diffusion law in spherical coordinate frame. In the original condition, coal particle gas adsorption has been a balanced state, when external stress changing, gas will transform from adsorbed state to unbound state, and adsorbent gas will diffuse from coal particle core to surface following both mass conservation and continuity principle. In the coal particle core, adsorbent gas concentration abides by Langmuir law In the coal particle surface, the mass transfer between adsorbent gas and dissociate gas abide...

A scenario for the evolution of a complex system must consist of plausible elementary steps, each conferring a distinct advantage (Darwinian continuity principle see also ref [27,67,218]). Furthermore, these steps also have to be physically plausible, which implies, in addition to the correspondence with physical laws, the continuity of underlying mechanisms and driving forces. Below, the interplay between the Darwinian and physical continuities in the Zn world is considered in more detail. 

If life emerged in the environments that had relatively high levels of Zn ions [97], the primordial life forms, which lacked the tools to alter their ionic content [187], should have had high Zn levels as well. In accordance with chemical continuity principle, the ionic content of the primordial environments should be conserved inside modern cells. This leads to the prediction no. 5 The total... 

Rule 2. Other regions The sequence in a given region outside the region (0 0) is to be determined by the continuity principle. That is, any two neighboring regimes of majority disorder should have one defect of the defect pairs in common.

The continuity principle holds in this case, as there is no creation or destruction of systems. The implication is that, when considering a closed phase space domain V, the net number of points leaving S per unit time equals the rate of decrease of points in volume V. This continuity principle can be expressed as follows ...
