Available in PDF, EPUB and Kindle. Book excerpt: Radio coronal condensations during the 20 May 1966 and 12 November 1966 solar eclipses were measured by AFCRL at wavelengths of 3.4, 6.0, 11.1 and 21.2 cm. Almost all condensation regions showed peak flux values lower than 10 to the ( -21)st power w/sq m/Hz. The flux spectra increased very slightly with increasing frequency, suggesting that thermal bremsstrahlung was the dominant emission mechanism. Only one source had a spectrum where gyromagnetic emission became dominant and caused peaking near the 6.0-cm wavelength. This source was associated with the strong bipolar spot group in McMath plage region 8573 of 12 November. A quiet-sun model that was developed to determine the source flux accounted for the east-west asymmetry, limb brightening, and polar darkening in the radio brightness distribution of the background sun. The angular size of sources was smallest, with least variations, at the 6.0-cm wavelength. Brightness temperatures of the condensations were measured at 4,700,000 degrees K (21.2 cm) during both eclipses. Flares, radio bursts, and other electromagnetic emissions originating in coronal condensation regions can cause false signatures on surveillance radars, affect satellite orbit parameters, and create ionospheric disturbances that degrade communications. Knowledge of the condensation region development is needed for early warning and prediction of potential solar disturbances. (Author).

Download or read book Chemistry3 written by Andrew Burrows and published by Oxford University Press. This book was released on 2021 with total page 1429 pages. Available in PDF, EPUB and Kindle. Book excerpt: Chemistry is widely considered to be the central science: it encompasses concepts on which all other branches of science are developed. Yet, for many students entering university, gaining a firm grounding in chemistry is a real challenge. Chemistry3 responds to this challenge, providingstudents with a full understanding of the fundamental principles of chemistry on which to build later studies.Uniquely amongst the introductory chemistry texts currently available, Chemistry3's author team brings together experts in each of organic, inorganic, and physical chemistry with specialists in chemistry education to provide balanced coverage of the fundamentals of chemistry in a way that studentsboth enjoy and understand.The result is a text that builds on what students know already from school and tackles their misunderstandings and misconceptions, thereby providing a seamless transition from school to undergraduate study. Written with unrivalled clarity, students are encouraged to engage with the text andappreciate the central role that chemistry plays in our lives through the unique use of real-world context and photographs.Chemistry3 tackles head-on two issues pervading chemistry education: students' mathematical skills, and their ability to see the subject as a single, unified discipline. Instead of avoiding the maths, Chemistry3 provides structured support, in the form of careful explanations, reminders of keymathematical concepts, step-by-step calculations in worked examples, and a Maths Toolkit, to help students get to grips with the essential mathematical element of chemistry. Frequent cross-references highlight the connections between each strand of chemistry and explain the relationship between thetopics, so students can develop an understanding of the subject as a whole.Digital formats and resourcesChemistry3 is available for students and institutions to purchase in a variety of formats, and is supported by online resources.The e-book offers a mobile experience and convenient access along with functionality tools, navigation features, and links that offer extra learning support: www.oxfordtextbooks.co.uk/ebooksThe e-book also features interactive animations of molecular structures, screencasts in which authors talk step-by-step through selected examples and key reaction mechanisms, and self-assessment activities for each chapter. The accompanying online resources will also include, for students:DT Chapter 1 as an open-access PDF;DT Chapter summaries and key equations to download, to support revision;DT Worked solutions to the questions in the book.The following online resources are also provided for lecturers:DT Test bank of ready-made assessments for each chapter with which to test your studentsDT Problem-solving workshop activities for each chapter for you to use in classDT Case-studies showing how instructors are successfully using Chemistry3 in digital learning environments and to support innovative teaching practicesDT Figures and tables from the book

Download or read book Planetary Nebulae written by D.E. Osterbrock and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 473 pages. Available in PDF, EPUB and Kindle. Book excerpt: This written account of the Symposium on Planetary Nebulae was prepared from manuscripts submitted by the participants. Nearly every paper that was presented at the meeting is reproduced here, in either complete or abbreviated form. The dis cussions have been somewhat shortened and rearranged, but we have tried to preserve the essential points and the general tenor of the exchanges. Participants who spoke in the discussion were asked immediately for written remarks, which were then edited, reproduced, and circulated at the meeting by the highly effective local Secretariat organized by Dr Perek. In addition, notes of the discussion taken by Mrs Edith F. Swan and by the undersigned were used. We wish to thank all the authors for their unusually good cooperation. We are especially grateful to Dr Minkowski, who kindly provided many excellent repro ductions of Mount Wilson and Palomar photographs, mostly taken by himself, of various planetary nebulae. We are particularly indebted to Mrs Swan, who attended the Symposium, made notes on the papers and discussions as they occurred, and did much of the checking and editing of the manuscripts. In addition, we are very grateful to Mrs Evelyn Seaver, who also did much of the checking, editing, and retyping of manuscripts, and to Dr B.L. Webster, Miss Rebecca Todd, Mr Joseph Tapscott, and Mr Dennis Schatz, who provided excellent assistance in the preparation of this volume.
