    Mathematics for the General Course in Engineering covers the syllabus in mathematics for the general course in engineering. Topics covered deal with arithmetic, logarithms, and mensuration, along with algebra, geometry, and trigonometry. Examples and the corresponding answers are given at the end of each chapter. This volume is comprised of six chapters and begins with an introduction to arithmetic, with emphasis on how to compute fractions, decimals, averages, ratio, percentages, reciprocals, squares and square roots, and errors. The next chapter deals with logarithms and considers positive and negative numbers, the use of brackets, and indices as well as the laws of logarithms and the use of logarithms in calculations. Subsequent chapters focus on mensuration (right prism, oblique prism, sphere, average-area rule, etc.); algebra (signs, maxima and minima, graphical solution of equations, etc.), geometry (angles, intersecting chords, radians, etc.), and trigonometry (special angles, identities, sine rule, cosine rule, etc.). This book will be a useful resource for students of mathematics and engineering.

  • Expression of Results in Quantum Chemistry

    Physical Chemistry Division: Commission on Physicochemical Symbols, Terminology and Units
    • 1st Edition
    • D. H. Whiffen
    • English
    Expression of Results in Quantum Chemistry recommends the appropriate insertion of physical constants in the output information of a theoretical paper in order to make the numerical end results of theoretical work easily transformed to SI units by the reader. The acceptance of this recommendation would circumvent the need for a set of atomic units each with its own symbol and name. It is the traditional use of the phrase ""atomic units"" in this area which has obscured the real problem. The four SI dimensions of length, mass, time, and current require four physical constants to be permitted. A table is included with the physical constants or mixtures of physical constants, to be normally used as a factor, to convert into SI the results of theoretical computations of a selected list of physical quantities. The first column lists these physical quantities, the second column shows their usual symbols, and the third column gives the mixture of physical constants X corresponding to each physical quantity. The descriptions of X are not unique but the value in SI is naturally unaffected by the form in which Xh is expressed. For convenience the final column of the table gives values of X to five significant figures. For higher accuracy the most recent table of physical constants should be used to re-evaluate the numbers. This monograph will be a useful resource for students, chemists, and physicists.

  • I.G.Y. Ascaplots

    Annals of the International Geophysical Year, Volume 20, Part II: I.G.Y. Ascaplots is a four-chapter text that provides the data on half-hourly auroral all-sky camera plots from 115 stations for the period 1958-1959. This period cover two winters in the northern hemisphere characterized by high auroral activity. This part also presents the list of stations, as well as the maps of the northern and southern distribution of all-sky cameras, with some modifications and additions to the earlier list. Data from the added Japanese station in the Antarctic are received and are included with the data from the 114 stations listed in the first part of the ascaplot volume. This book will prove useful to geophysicists.

  • Native Orchids of Trinidad and Tobago

    • English
    Native Orchids of Trinidad and Tobago provides detailed descriptions of the native species and varieties of orchids from Trinidad and Tobago. The Orchidaceae is the largest family of flowering plants with between 15,000 and 20,000 known species and varieties in from 500 to 600 genera; and new ones are being discovered by almost every botanical expedition to tropical areas. In Trinidad and Tobago, the Orchidaceae is the second largest family of flowering plants in terms of number of species. The native species and varieties known at the present time number 181, and they belong to sixty-six genera. The genera are enumerated in strict phylogenetic sequence, in accord with SCHLECHTER'S system. The species are listed alphabetically under the genera. An attempt has been made throughout to indicate synonymy as completely as possible even to the inclusion of binomials, which have never been used in connection with the flora of Trinidad and Tobago. The description of each genus has for the most part been drawn up to cover the morphological limits shown by the concept throughout its entire geographic range, whereas the specific descriptions are usually based only upon material collected in Trinidad and Tobago.

  • Fate and Effects of Petroleum Hydrocarbons in Marine Ecosystems and Organisms

    • English
    Fate and Effects of Petroleum Hydrocarbons in Marine Organisms and Ecosystems is a collection of papers presented at the international symposium by the same title, held at the Olympic Hotel in Seattle, Washington on November 10-12, 1976. This book is organized into three parts encompassing 46 chapters. Part I deals with the inputs and physical transport processes influencing the distribution and composition of petroleum hydrocarbons in marine systems. Part II discusses the bioaccumulation and metabolism of hydrocarbons by marine organisms. Part III contains papers that tackle the biological and ecological effects of petroleum exposure in marine systems. This book is of great value to marine and environmental scientists and researchers.

    • English
    Solubilities of Inorganic and Organic Compounds, Volume 2: Ternary and Multicomponent Systems, Part 2 presents the solubility data of ternary and multicomponent systems. The text arranges the data in a way that the first Tables are systems in which an Element is a component, which are followed by data for systems containing inorganic compounds, metallo-organic compounds. Next, the selection presents the systems in which water is one component and the remaining components being organic. The book will be of great use to students of chemistry and chemical engineering.
