[...]... journals Thermal Analysis and Calorimetry (JTAC) and Thermochimica Acta (TCA), which cover the entire field of thermal analysis and related thermophysical studies, and which naturally belong to a broader domain of journals concerned with material thermal science [26] These two journals are members of a general family of about 60 000 scientific journals that publish annually about 10^ papers on 10^ pages... kinds of analysis However, because of the multitude of existing data of interest to material thermal science and technology, and the variety of modes of presentation, computer-assisted extraction of numerical values of structural data, physicochemical properties and kinetic characteristics from primary sources are almost as difficult as before As a consequence, the collection of these data, the assessment... way to make some data inaccessible is to file them in a large database Curiously, large databases may be even seen to act like astronomical black holes in the information domain The steadily growing databases may distract a large number of scientists from their active research, but it can also give jobs to new specialists engaged in information and data assessment itself Scientists may spend more and. .. assessment of their quality in specialized data centers, the publication of handbooks and other printed or electronic secondary sources (compilations of selected data) or tertiary sources (collections of carefully evaluated and recommended data), storage in data banks, and dissemination of these data to end users (educational institutions and basic scientific and applied research centers), still remain tedious... understanding of thermodynamic variables as averaged quantities and the assignment of such variables to individual parts that may be composed together to form other parts [9, 20] Another important standpoint is the distinction between 'phase' as the denomination of a certain intensive state and the different forms of matter (as liquids or solids) Tn fact, phase keeps traditional meaning as a 'homogeneous... journals The territory of thermal treatment and analysis could thus become the most generally enhanced aspect of reactivity studies - why? The thermal properties of samples are monitored using various instrumental means Temperature control is one of the basic parameters of all experiments, but there are only a few alternatives for its regulation, i.e., isothermal, constant heating/cooling, oscillating and. .. the bar and the hand Therefore the iron bar would feel to us colder Curiously, this is somehow similar to the artificial parameter called entropy that explicates different qualities of heat with respect to the actual temperature Certainly, and more realistically, it should be related to the modem understanding of transient thermal property known as warm-cool feeling of fabrics (particularly applied to. .. paragraphs of already-existing papers so as to create new papers, fitting them into (and causing no harm in) the category of "never-read" articles Prevention or restriction of such an undesirable practice is mostly in the hands of scientific referees (of those journals that do review their articles) and their ability to be walking catalogues and databases in their specialization The extent of the task facing... manipulation of numbers and symbols Recently, there has arose computing with words, in which the objects of computation are propositions drawn from a natural language, e.g., small, large, light, dark, heavy, close, far, easy, difficult, etc Such manipulation is inspired by the remarkable human capability to perform a wide variety of physical and mental tasks without any measurements and any calculations,... icy, arctic, glacial, etc., again, too many denominations to make an optimal choice We, however, would feel a different effect of sensation in our hand if in contact with an iron or a wooden bar that are both of the same temperature Here we, moreover, are unintentionally making a certain normalization of our tactility by accidentally regarding not only the entire temperature of the bar but also the heat . specialized journals. Thermal Analysis and Calorimetry (JTAC) and Thermochimica Acta (TCA), which cover the entire field of thermal analysis and related thermophysical studies, and which naturally. thermal analysis, and the associated field of overlaying thermophysical studies, to gain a better understanding of the science of heat or, if you like, thermal physics or science of heat. It can. feeling of fabrics (particularly applied to textiles) related to thermal absorptivity (characterizing heat flow between human skin and fabrics at given thermal conductivity and thermal capacity).
