Hardback. Condizione: New. ETHNIC DERMATOLOGY Principles and Practice Richly pigmented skin is the most common skin type internationally Historically, dermatology has focused on white skin. But rich pigmentation can lead to differences in presentation, disease course and outcome, and reaction to treatment. Some dermatologic conditions are seen either predominantly or exclusively in richly pigmented skin. Ethnic Dermatology: Principles and Practice provides a practical approach to the dermatology of nonwhite skin. Written from a global perspective to include Asian, African-Caribbean and North African skin types, it covers all the bases of dermatology including: Grading scales in dermatologic diseasePediatric dermatologyDermatology and systemic diseaseDrug eruptionsHair and scalp disordersCosmetic dermatology. With a central focus on practical action from an international cast of authors, Ethnic Dermatology: Principles and Practice gives you the clinical tools you need when skin color matters.…

Erste Ausgabe ihrer ersten gemeinsamen Arbeit zum Dulong-Petischen Gesetz. - "In 1815 Dulong's famous collaboration with the mathematical physicist Alexis Thérèse Petit began; it produced three important memoirs on heat. The best-known part of this work is the statement of the law of constant atomic heats that bears their names, They began with the fundamental problem of measuring quantities of heat, which involved a critical analysis of thermometric scales. In 1804-1805 Gay-Lussac had carried out a comparison of mercury and air thermometers between 0°C. and 100°C. Dulong and Petit extended the range of comparison up to 300°C. and found an increasing discrepancy between the two scales at higher temperatures" (DSB). - Name auf Vorsatz und Stempel auf Titel.

Hardcover. Condizione: Very Good. Introduction of the Dulong-Petit Law, a fundamental step in statistical physics. [++] Pierre DULONG and Alexis Petit, "Recherches sur la Mesure des Temperatures et sur les lois de la communication de la chaleur", pp 150-161 AND pp 239-249, in Bibliotheque Universelle, Geneva, Imprimerie Bibliotheque Universelle, 1819, volume 10, viii, 304pp, folding plate. Bound in paper covered boards, gilt stamped title on spine. Provenance: Staatsbibliothek, Berlin, and also from "Kong. Bergwerks Bibliothek", (Royal Mining Library) with their two small stamps on the title page. Ex-library: paper call number on bottom spine, and aside from these two bits there are no other markings. The binding is tight, the book strong and squared, and the text is very fresh and crisp. GOOD/VERY GOOD copy. There is some faded black smudging on the bottom of the text block which cannot be seen in the interior of the book. [++] Dulong and Petit occupies pp 150-161 AND pp 239-249. It seems to me that the paper first appeared slightly earlier in the year and about 40% longer in "Annales de Chime et de Physique" for 1819. "Pierre Dulong (1785-1838, French) and Alexis Petit (1791-1820, French) find that many substances have molar heat capacities of approximately 6 cal/mole C, implying, through the constancy of the molar heat capacities, that the specific heats tend to be inversely proportional to the atomic weights. The result is announced in the paper "Recherches sur quelques points importants de la théorie de la chaleur" [Researches on several important points of the theory of heat]."--Parkinson, Breakthroughs (1819). The Dulong-Petit limiting law for the specific heats of solids, one of the first general results in thermodynamics, has provided Mendeleev with a powerful tool for devising the periodic table and gave an important support to Boltzmann s statistical mechanics. Even its failure at low temperature, accounted for by Einstein, paved the way to the the quantum mechanical theory of solids." -- "The strange case of Dr. Petit and Mr. Dulong," Roberto Piazza, 2018. "They were concerned with the specific heats of elements; but if these elements really existed as atoms, it seemed possible that there might be a connection between the weight of the atom and the amount of heat acquired to raise the temperature of a given weight of that element by a certain amount."--Complete Dictionary of Scientific Biography online. [++] "The Dulong Petit law, a thermodynamic law proposed in 1819. states the classical expression for the molar specific heat capacity of certain chemical elements. Experimentally the two scientists had found that the heat capacity per weight (the mass-specific heat capacity) for a number of elements was close to a constant value, after it had been multiplied by a number representing the presumed relative atomic weight of the element. These atomic weights had shortly before been suggested by John Dalton and modified by Jacob Berzelius." --Wikipedia) [++] BIOT, "Notice sur la continuation des traveux enterpris pour determiner la figure de la Terre." pp 225-238.

Gay-Lussac et Arago.", Vol. 7 and vol. 10, Cahier 4. - 448 pp. a. 2 engraved plates (entire vol. 7 offered) + pp. 337-443 a. 2 engraved plate (entire issue offered, Cahier 4 of vol. 10 with htitle to the vol.). Dulon & Petit's papers: pp. 113-154, pp. 225-264, pp. 337-367 and Vol. X, pp. 395-413. First edition of these 4 groundbreaking papers with the first appearance in print of THE LAW OF THE CONSTANCY OF ATOMIC HEAT, i.e. the specific heat multiplied by the atomic weight. The insight had far reaching implications as it showed a new way to Dalton's atomic theory. "In 1815 Dulong's famous collaboration with the mathematical physicist Alexis Therese Petit began" it produced three importent memoirs on heat." (the papers offered here). The 2 first was awarded the price of the Academy in 1818 and was leading up to the last paper in which they formulted the "Law of the Constancy of product of atomic weight and specific heat"They (Dulang and Petit) were concerned with the specific heats of elements" but if these elements really existed as atoms, it seemed possible that there might be a connection between trhe weight of the atom and the amount of heat aquired to raise the temperature of a given weight of that element by a certain amount." (DSB). "One of his (Dulong) most importent researches was made in collaboration with Alexis Thérese Petit (1791-1820), with whom he announced the law that the product of atomic weight and specific heat is constant (1819). It rendered a distinct service in fixing atomic weights, especially when these were in question, and enabled Berzelius and later Cannizzaro to arrive at correct atomic weights and the correct number of atoms in molecules."
