Existence areas

If the new increased heat duty and new log mean temperature difference are fixed, then the additional surface area above the existing area using a plain tube surface is given by9 ... 

At the increased flowrate condition, the outlet temperatures and heat duty for the existing area are unknown.

The biosensor research areas including modern biospeciflc analytical techniques are developing very rapidly and it is fair to say that analytical chemistry plays a very important role in these developments. New challenges lie ahead with new discoveries and tools opening up novel dimensions in both fundamental research and in possible applications. However, as in many other areas in analytical chemistry for major breakthroughs, we rely on developments in other areas that have contributed and will contribute to new research directions as well as successful improvements in already existing areas. 

Lapse Temperature Gradient (Unstable-U). This condition normally exists on a clear day when the middle and low clouds cover less than 30 percent of the sky and when the wind speed is less than 5 kmph. It is the least favorable condition for the enemy to employ chemical or biological agents. When a lapse condition exists, area coverage without diffusion will be enhanced with a steady low wind speed of 3 to 7 kmph.

A system with two variables can be graphically illustrated either three-dimensionaUy or by projecting into a plane defined by axes on which the values of variables are plotted. So-called diagrams of predominating existence area (stability field diagrams) are obtained. 

Based on the results of X-ray phase and stmctural analysis of the Lai xCaxCri yTiy03 samples synthesized by a ceramic technique in air at 1620 K, the isothermal sections of the CaTi03-LaCr 03-CaCr 03 quasi-temary system has been constmcted [3]. Extended solid solution with perovskite-like GdFe03-type of stmcture (space group Pbnm) is formed in this system in a wide homogeneity range. The existence area of the solid solution at used experiment conditions reaches up to 0.6- -0.7 molar fractions of CaCr 03. 

In paper [1] the curves Q(t) were described in terms of the scaling approaches for low molecular substance reactions [11]. Let us consider the reaction in which particles P of chemical substance are diffused in the environment containing randomly located nonsaturated statistical traps T. At the point of contact of a particle P with trap T the particle disappears. Nonsaturation of a trap means that the reaction P+T T can be repeated an infinite number of times. It is usually considered that if the concentration of particles and traps is large or the reaction proceeds at intense stirring, the process can be considered as classical reaction of the first order. However, if the concentration of the randomly located traps is small, with necessity there exist areas of space, practically free from traps. The particles that are in these areas, can reach traps only for rather long time and, hence, the fall of their number with time grows slower in comparison with the reaction of the first order. The formal analysis of this problem shows that the concentration of particles falls down under the law [11] ...

The Privacy Act prevents industry from generally releasing information on individual cases which could be traced back to the person involved. This may hinder efforts to estimate occupational exposures for pollutants for which published literature does not already exist. Area monitoring data may, however, be released by industry upon request and can provide a general indication of nearby worker exposure. 

Newer adhesives of the acrylic, anaerobic or radiation-curable types must, if they are structural, have a relatively high degree of toughness and durability if they are to compete with or challenge epoxy adhesive systems. Likewise, newer radiation-curable, pressure-sensitive adhesive systems must exhibit the properties of permanence largely associated with cross-linked adhesive masses deposited from an acrylic solution polymer base. Epoxy resin structural adhesives largely define the existing area on the one hand the cross-linked acrylics deposited on plastic or metallic films the other. 

There are existence areas in phase diagrams in which one phase is stable and coexistence areas where two phases are in equilibrium. Line compounds (very narrow existence regions) are phases that have very low solubility for the separate...

In this work, the mentioned subject is continued and developed. From theoretical reasons, it is assumed that second liquid can exist not only in the lower part of phase plane (on the sublimation curve) but also in its upper part, in all existence area of ordinary liquid. The point comes to the sizes of liquid objects if only one dimension of a liquid object does not exceed a certain critical size he, this object has to consist of second (not ordinary) liquid. This conclusion ought to be of an important applied significance. 

Imagine that we have the concrete and sufficiently exact sizes he and ho of a certain chemical substance, obtained experimentally. In which relation could be these sizes Let us assume that they must be equal. This assumption has important heuristic contents which might be used to understand and substantiate the uniquity of properties of nanomateiials. Indeed, if one would take this assumption, the accepted nanometric range would acquire a profound physical meaning it is the existence area of corresponding second liquid. 

In the model the existing areas can be used (AHE,ex) by enlarging them with additional areas (AHE,add)- The additional annual depreciation of enlarged and new areas (AHE,new) of heat exchangers and pipings (Table 1), is multiplied by the payback multiplier (r = 0,2448) to obtain the maximum annual profit of heat and power integration ...
