Cohesion pressure in liquid due to inward intermolecular force on surface molecules, not surface tension, causes minimization of liquid surface. Surface tension isn't what causes horizontal wire sliding on two limbs of a U-shaped wire to be in equilibrium in any position. Incorrectness of current relations for pressure differences between inside and outside of a bubble and one related to a solid drop is proven. In surface evaporation liquid increases the potential energy of its molecules by taking heat while their kinetic energies remain unchanged. Gas temperature decreases due to surface evaporation while some net heat is transferred from gas to liquid. So if gas temperature is only a little lower than liquid temperature, some net heat will be still transferred from gas to liquid due to surface evaporation and finally gas and liquid will be isothermal in a temperature lower than the initial temperature. This violates the 2nd law of thermodynamics. An equation is presented in case of its solving wave equation can be solved for general spreading of cylindrical wave. Using it, general spreading of cylindrical wave for large distances is obtained which consists of arbitrary functions.

The advance of scienti?c thought in ways resembles biological and geologic transformation: long periods of gradual change punctuated by episodes of radical upheaval. Twentieth century physics witnessed at least three major shifts — relativity, quantum mechanics and chaos theory — as well many lesser ones. Now, st early in the 21 , another shift appears imminent, this one involving the second law of thermodynamics. Over the last 20 years the absolute status of the second law has come under increased scrutiny, more than during any other period its 180-year history. Since the early 1980’s, roughly 50 papers representing over 20 challenges have appeared in the refereed scienti?c literature. In July 2002, the ?rst conference on its status was convened at the University of San Diego, attended by 120 researchers from 25 countries (QLSL2002) [1]. In 2003, the second edition of Le?’s and Rex’s classic anthology on Maxwell demons appeared [2], further raising interest in this emerging ?eld. In 2004, the mainstream scienti?c journal Entropy published a special edition devoted to second law challenges [3]. And, in July 2004, an echo of QLSL2002 was held in Prague, Czech Republic [4]. Modern second law challenges began in the early 1980’s with the theoretical proposals of Gordon and Denur. Starting in the mid-1990’s, several proposals for experimentally testable challenges were advanced by Sheehan, et al. By the late 1990’s and early 2000’s, a rapid succession of theoretical quantum mechanical ? challenges were being advanced by C ́ apek, et al.

The first of two volumes, this edited proceedings book features research presented at the XVI International Conference on Hyperbolic Problems held in Aachen, Germany in summer 2016. It focuses on the theoretical, applied, and computational aspects of hyperbolic partial differential equations (systems of hyperbolic conservation laws, wave equations, etc.) and of related mathematical models (PDEs of mixed type, kinetic equations, nonlocal or/and discrete models) found in the field of applied sciences.

Modern Engineering Thermodynamics - Textbook with Tables Booklet offers a problem-solving approach to basic and applied engineering thermodynamics, with historical vignettes, critical thinking boxes and case studies throughout to help relate abstract concepts to actual engineering applications. It also contains applications to modern engineering issues. This textbook is designed for use in a standard two-semester engineering thermodynamics course sequence, with the goal of helping students develop engineering problem solving skills through the use of structured problem-solving techniques. The first half of the text contains material suitable for a basic Thermodynamics course taken by engineers from all majors. The second half of the text is suitable for an Applied Thermodynamics course in mechanical engineering programs. The Second Law of Thermodynamics is introduced through a basic entropy concept, providing students a more intuitive understanding of this key course topic. Property Values are discussed before the First Law of Thermodynamics to ensure students have a firm understanding of property data before using them. Over 200 worked examples and more than 1,300 end of chapter problems provide an extensive opportunity to practice solving problems. For greater instructor flexibility at exam time, thermodynamic tables are provided in a separate accompanying booklet. University students in mechanical, chemical, and general engineering taking a thermodynamics course will find this book extremely helpful.

The recently proposed, fully multi-scale theory of doublet mechanics offers unprecented opportunities to reconcile the discrete and continuum representations of solids while maintaining a simple analytical format and full compatibility with lattice dynamics and continuum mechanics. In this monograph, a self-contained account of the state of the art in doublet mechanics is presented. Novel results in the elastodynamics of microstructured media are reported, including the identification of a new class of dispersive surface waves, and the presentation of methods for the experimental determination of the essential microstructural parameters. The relationships between doublet mechanics, lattice dynamics, and continuum theories are examined, leading to the identification of the subject areas in which the use of doublet mechanics is most advantageous. These areas include the analysis of domains as diverse as micro-electro-mechanical systems (MEMS), granular and particulate media, nanotubes, and peptide arrays.
