This note is concerned with the correlation and presentation of information on heat transfer under conditions of turbulent forced convection for the flow of gases in tubes. Discussion will be confined to the region where thermal entrance effects are absent and, furthermore, it will be assumed that the flow velocity is sufficiently low for compressibility effects to be neglected.The subject matter will be discussed in general terms only and it is not intended to produce quantitative conclusions, which may, however, be found in reference 11.

This article examines the inception of writing on Crete in the second millenniumbcfrom a fresh methodological perspective. It aims to develop a synoptic understanding of the origin, purpose, experience, and significance of the earliest attestations of writing on the island, to investigate the context of its creation, and to explore the cultural triggers that underlie the application of writing in the context of Middle Minoan Crete. Three key points are considered: the problematic definition of early writing on Crete, the possible identification of the subject matter of the Cretan hieroglyphic inscriptions on sealstones, and the script's level of indebtedness to pre-existing models. These paths of investigation are also crucial points of departure for understanding the phenomenon of early writing in more general terms, from a multidisciplinary perspective that seeks to advocate a synergic collaboration between anthropology, archaeology, epigraphy and sociolinguistics.

This chapter focuses on the Coverage Clause in Article I of the Bermuda Form XL004. Article I is the shortest of the major policy divisions. Despite its brevity, it provides an outline or framework of the Bermuda Form policy as a whole, including references to the most important terms, each of which is defined in Article III of Form XL004 and without which the policy cannot reasonably be understood. The Coverage Clause is central to the operation of the Bermuda Form. It describes in general terms the nature, overall scope, and fundamental principles of the coverage provided. The chapter discusses the persons and entities insured, the subject-matter of the coverage, and notice as a pre-condition to coverage.

Theory Of Literature

Hamlet is well-known as the most famous tragedy written by William Shakespeare. This dramatic work has, throughout the centuries, lead numerous writers, poets, literary-critics and philosophers to think about universal issues of life, human nature, love, loyalty and friendship. Hamlet has not just been the subject of discussion from the point of view of the theory of literature and human psychology and philosophy, it has also directly inspired the creation of many artistic works. One of those works which forms the main subject-matter of this paper is the almost unknown music for Hamlet by Enriko Josif. Enriko Josif was an extraordinary figure, a versatile artist and thinker, almost a kind of philosopher. In his opinion and in accordance with his inner feeling, art was a matter of divine creation first of all. He admired those artists who dealt with difficult issues of life in their works of art and William Shakespeare was to him one of the most prominent among them. In general terms, we have highlighted certain general points about Josif?s views on an artist?s life and work and have presented our notions about his piece. Specifically, we have tried to point out personal views that Josif held about Hamlet, as well as the most important features of Josif?s music, which are broadly in accordance with the literary, ethical, philosophical and theological critical tradition surrounding this masterpiece.

An experimental investigation has been carried out for almost the first time to examine the heat transfer by forced convection and subcooled boiling from a finned water-cooled engine cylinder head using steady state technique. Cast iron and cast steel specimens with and without fins have been used in the present work. The effects of flow velocity, coolant bulk temperature, fin length, fin number and fin material have been examined. It has been found that the use of finned cylinder head surface greatly improves the forced convection heat transfer coefficient and subcooled boiling heat flux as the fin length and number influenced the heat transfer process. The cast iron specimen exhibited better heat transfer characteristics over the cast steel one. The effects of bulk flow velocity and temperature for flat and finned specimens have been evaluated for forced convection and subcooled boiling. A correlation has been developed to relate the Nusselt number with Reynolds’ number, Prandtl number, viscosity ratio and fin length ratio, for forced convection from the cast iron specimen, which read: Nu=0.023Re0.697Pr0.33μr0.14(1+A)0.623

Points Of View

This book is an excellent primer for the uninitiated pediatrician. The points of view expressed are sound, and the substantive material is based on a thorough understanding of the subject matter. The book is well organized and is divided into three sections. The first section describes in very general terms an overview of psychological development during childhood from a psychoanalytic standpoint. The second section consists of brief descriptions of seven major types of problem children, including such topics as children who are neurotic, psychotic, psychosomatically ill, mentally retarded, brain damaged, or who have a behavior disorder or a learning disorder.

The Comparative Study

AbstractA comparative study of religion rests on comparison and generalization. Both require that the object of study, the subject matters of various religions have something in common - certain properties that warrant their juxtaposition in analyses. If they had nothing in common, "the study" of religion would not make any sense. But it seemingly does, thus "religions" presumably form a subject matter with certain regularities. Such regularities may be "emic universals" on the level of socio-cultural formations and they may be "etic universals" on the levels of the analysts' stock of general terms - and the two levels are connected. This article focuses mainly on the role of universals as general concepts in method and theory, i.e., on the status and use of etic level generalizations such as models, maps, metaphors that are constructed in order to explain and make sense, as general terms, of emic level entities, properties, functions, structures etc. The last part concerns the use of universals in four modes of comparison of material, cognitive and symbolic matters.

Vibrational Velocity

The effect of vibration on free and forced convection heat transfer from spheres was investigated. Test spheres made of copper were subjected to sinusoidal vibration in the vertical plane, this being perpendicular to the direction of airstream in the case of forced convection studies. In free convection studies the amplitude of vibration was varied from 4 mm to 25.5 mm and the frequency of vibration from 150 cpm to 930 cpm. It was found that the effect of vibration on Nusselt number was negligible for values of vibrational Reynolds number less than 200. For values of vibrational Reynolds number greater than 200, the vibration increased the heat transfer coefficient considerably and values of heat transfer coefficients as high as seven times the free convection values without vibration were obtained. The following correlations were obtained for heat transfer from spheres to air: freeconvectionwithoutvibration,NNu=2+0.401(NGr)0.25for4×103<NGr<6×104 and free convection with vibration: hvho=0.83(NRe)v0.5(a/D)0.1(NGr)0.251.28 In the case of forced convection studies with vibration, the amplitude of vibrations varied between 4 mm and 12.4 mm, and the frequency of vibration from 200 cpm to 1600 cpm. The flow velocity was varied from 24.5 ft/sec to 84 ft/sec. The results in the absence of vibration could be represented by: NNu = 0.304 (NRe)0.56 or NNu = 2 + 0.222 (NRe)0.587 in the range 6 × 103 < NRe < 3.3 × 104. Nusselt numbers were not found to be affected by the imposition of vibrational velocity even as high as 19.6 percent of the flow velocity.
