Learning Mathematics - Class 9 has been written by Mr. M.L. Aggarwal (Former Head of P.G. Department of Mathematics, D.A.V. College, Jalandhar) in accordance with the latest term-wise Syllabus and Guidelines issued by the CBSE on Comprehensive and Continuous Evaluation. The subject matter contained in this book has been explained in a simple language and includes many examples from real life situations. Carefully selected examples consist of detailed step-by-step solutions so that students get prepared to tackle all the problems given in the exercises. Questions in the form of Fill in the Blanks, True/False Statements and Multiple Choice Questions have been given under the heading ‘Mental Maths’. In addition to normal questions, some ‘Higher Order Thinking Skills (HOTS )’ questions have been given to enhance the analytical thinking of the students. A ‘Chapter Test’ has been put in the end of each chapter which serves as the brief revision of the entire chapter. Term-wise Model Question Papers for Formative and Summative Assessments have been given at proper places.

A landmark event in literary scholarship, the publication of the Johns Hopkins edition of The Complete Poetry of Percy Bysshe Shelley makes available for the first time critically edited clear texts of all poems and translations that Shelley published or circulated among friends, as well as diplomatic texts of his significant incomplete poetic drafts and fragments. Edited upon historical principles by Donald H. Reiman and Neil Fraistat, the multi-volume edition will offer more poems and fragments than any previous collective edition, arranged in the order of their first circulation. These texts are followed by the most extensive collations hitherto available and detailed commentaries that describe their contextual origins and subsequent reception. Rejected passages of released poems appear as supplements to those poems, while other poetic drafts that Shelley rejected or left incomplete at his death will be grouped according to either their publication histories or the notebooks in which they survive. Writing to his publisher in 1813, Shelley expressed the hope that two of his major works "should form one volume"; nearly two centuries later, the second volume of the Johns Hopkins edition of The Complete Poetry fulfills that wish for the first time. This volume collects two important pieces: Queen Mab and The Esdaile Notebook. Privately issued in 1813, Queen Mab was perhaps Shelley's most intellectually ambitious work, articulating his views of science, politics, history, religion, society, and individual human relations. Subtitled A Philosophical Poem: With Notes, it became his most influential -- and pirated -- poem during much of the nineteenth century, a favorite among reformers and radicals. The Esdaile Notebook, a cycle of fifty-eight early poems, exhibits an astonishing range of verse forms. Unpublished until 1964, this sequence is vital in understanding how the poet mastered his craft. As in the acclaimed first volume, these works have been critically edited by Donald H. Reiman and Neil Fraistat. The poems are presented as Shelley intended, with textual variants included in footnotes. Following the poems are extensive discussions of the circumstances of their composition and the influences they reflect; their publication or circulation by other means; their reception at the time of publication and in the decades since; their re-publication, both authorized and unauthorized; and their place in Shelley's intellectual and aesthetic development.
Comprehensive resource presenting the fundamentals and state of the art concepts, design examples, relevant components, and technology Slow-wave Microwave and mm-wave Passive Circuits presents the fundamentals and state of the art concepts, design examples, relevant components, and technology of the subject, plus examples of circuit layout optimization using slow-wave circuits. In one volume, the recent advances in aspects of the slow-wave concept are covered. Potential applications include automotive radars, medical and security applications, and 5G and future 6G for very high-speed communications. The text considers a variety of slow-wave structures and associated concepts which are useful for circuit design. Each structure is electrically modeled with clear illustration. The highly qualified authors show that the use of the slow-wave concept can, in some cases, improve the performance of passive circuits. The techniques proposed make it possible to reduce the size and/or the performance of the circuits, with a beneficial cost-saving effect on semiconductor materials. Concepts are applied to several technologies, namely CMOS, PCB (Printed Circuit Board) and nanowires. Sample topics covered in Slow-wave Microwave and mm-wave Passive Circuits include: Concepts of energy storage with examples of slow-wave CPW (S-CPW), slow-wave SIW (SW-SIW), and slow-wave microstrip (S-MS), Transmission line topology and application in integrated technologies (CMOS), including possibilities offered by the BEOL (Back-End-Of-Line), Effect of the geometrical dimensions on the transmission line parameters (Zc, α, εreff, and Q) and comparisons between conventional CPW and CPS, and slow-wave CPW and CPS, Performance of slow-wave coupled lines and comparison with conventional microstrip coupled lines. Slow-wave Microwave and mm-wave Passive Circuits is a highly useful resource on the subject for graduate students (best complemented with a basic book on microwaves), engineers, and researchers. The text is also valuable for physicists wishing to implement comparable techniques in optics or mechanics.
First modern edition and translation of the homilies of one of the most important religious figures of his time. Ælfric of Eynsham stands supreme as a distinguished homilist, translator, and moralist - one whose writings were sought by the most powerful churchmen and landed warlords of his day. In his sermons, the dead are raised to life, innocents are betrayed, civilizations come to ruin, prophecies are finally fulfilled, and sorrow is swallowed up in salvation. He offers guidance regarding sex, financial counsel, botanical excursuses, etymological asides, lions cowed by roosters, arch-heretics disemboweled, and seemingly inconsequential figures receiving everlasting crowns. He also considers the origin of Antichrist, recounts supernatural visions of damnation and deliverance, teases out the tension between predestination and free will, explores the multifarious nature of the soul, seeks to categorize creation, and presses the boundaries of conceptual capacity in describing the divine nature. Treatises take up such subjects as the Holy Spirit, cognition, penitence, and proper comportment. Private prayers appear alongside public declarations of the Christian faith found in the Paternoster and the Apostles' and Nicene Creeds. The thirty-one texts presented here, with facing translations, span the course of his career: Old English and Latin, ordinary and alliterative prose, pithy prayers and exhaustive exegesis. Nine appear in print for the first time; others for the first time in well over 100 years. Introductions to the texts offer overviews of the content, composition, and circulation of each work, using the fruits of the latest research to envision real-world contexts for their use in specific places, among particular groups, and by certain individuals. Meanwhile, the commentary traces Ælfric's role in the history of ideas, examining his relationship to over 100 sources, 200 other Ælfrician works, and over 1,000 biblical passages; it seeks to clarify Ælfric's compositional aims and further to establish the authorship and date of these remarkable writings from early England.
