        BITUMINOUS ROAD CONSTRUCTION IN INDIA

        by KANDHAL, PRITHVI SINGH

        This is the first ever text-cum-reference book in India on “Bituminous Road Construction”. It includes references to the codes and specifications of the Indian Roads Congress and the Bureau of Indian Standards, besides the international standards such as ASTM and AASHTO. This book provides a thorough knowledge of bituminous road construction such as bitumen; aggregate; mix design; special mixes, for example, stone matrix asphalt, warm mix asphalt, and ready-made pothole mix; structural design of flexible pavements; asphalt production and construction; distresses in asphalt pavements; maintenance and rehabilitation of asphalt pavements including recycling; and interesting investigations of premature failure of asphalt pavements across the world. It includes numerous simple, practical and illustrative examples, and a large number of photographs for easy comprehension of the subject matter.   This book has been designed to serve as a text for the undergraduate and postgraduate students of Civil Engineering for the courses on: Highway Materials including Testing Laboratory; Asphalt Mix Design; Highway Construction and Maintenance; Highway Pavement Failures; and Design of Flexible Pavements.   In this Revised Edition, it introduces Superpave Asphalt Binder Tests and Specifications (see Appendix A). Since over 95% of highways have bituminous surface, this book is also an ideal reference book for thousands of practicing highway engineers who are engaged in the most ambitious highway construction programme ever in India. Cutting-edge technology on bituminous road construction included in the book helps M.Tech and Ph.D. students in conducting research in this field and prepares them to implement their knowledge in real-life practice.   Google Preview: https://bit.ly/3C4edmo

        Things I Didn't Throw Out

        by Marcin Wicha

        Marcin Wicha (1972) is a Polish designer, illustrator, columnist, and writer. Having written a few books for children, he turned to adult non-fiction with a personal slant, of which the present book is the second instance, after his debut, How I Stopped Loving Design, was published to popular and critical acclaim in 2015, also by Karakter. Things I Didn't Throw Out is told in short, anecdotal chapters, collected in three sections: „My Mother's Kitchen”, „Dictionary”, and „Laughing at Appropriate Moments”, and forms a loose diptych with How I Stopped Loving Design, which focused on Wicha's father in the aftermath of his death (both books work as stand-alones, too).The book is a first-person account of processing grief through the objects his mother, Joanna, surrounded herself with while living and dying. The first part is mainly devoted to Joanna's books and how they formed a part of her life in its various stages. The second is a series of stories about objects (such as her typing machine and her ballpoint pens), mementoes, phrases and words that were important in Joanna's life and which allow us to construct an image of her as a person, a mother and a Jewish woman living in Communist Poland. The third, shortest one is a stark, unflinching report of her final illness and death.Wicha meditates on the obsolescence of objects after their owner dies. The book is a collection of memories of a difficult person who lived in a difficult time – Wicha realistically describes the material meanness of the Communist regime, the shortages, rudeness and the hoarding instincts shaped by post-war reality. Joanna's Jewishness, her devotion to work, her argumentative temperament, the clarity and no-nonsense quality of her opinions - all that accumulates into a fully fleshed-out character whose decline and death is then described in terse, unsentimental, yet very touching scenes. The result is cathartic.In the first section, Wicha deconstructs the post-war history of Poland in a series of chapters which transform his mother's bookshelves into an almost geological accumulation of many decades of sediment. During his childhood, in times of economic crisis, he has to stage a long war of attrition with a bookshop sales assistant in order to buy the new Tove Jansson book. In a long chapter analysing the caustic wit of Jane Austen's Emma, Wicha describes his mother's passionate relationship with that book, which always consoled her in times of low mood, but couldn't do the trick after her husband's death. He looks for the background stories in the little doodles on the margin, the tiny hole on one page, finds the history of socio-economic transformation of 20th century Europe in his mother's cookbooks, and mentions his mother's jokey ambition to move to Canada, reflected by her English textbook.The second section has a broader context of politics and history. Wicha describes politics as an excuse not to talk about personal problems; his mother's was a life spent with politics in the foreground, because there was no other way. Wicha explores the common, generational trauma of March 1968, when the remaining Polish Jews, frequently hiding their identity, were subject to a campaign of intimidation and social cleansing. In chapters seemingly about trivia, Wicha writes about the legacy of a community of people which was annihilated – about how they continue to be present in tasteless jokes, awkwardly-worded memorial signs, allusions during family gatherings. This section shows incredible sensitivity to the layers of global, local and personal histories that add up and intertwine.In the third section the short chapters are untitled, which adds to the fragmentary nature of the text and the impression that Wicha is barely holding it together. In between conversations with his mother's live-in Ukrainian nurse, doctors, paramedics and his mostly non-responsive mother, Wicha attempts to carry on and make sense of what is happening, give it meaning. The last six short chapters deal directly with his mother's death; they encompass the formalities and banal details that he has to attend to, the unbearable pain and helplessness, the need to keep going. Thus concludes this archeology of love, exasperation and grief, not without moments of dark humour.The book would be perfect for readers interested in: exploring the parent-child relationship, especially (but not exclusively) at the end of the parent's life, and issues of processing grief and remembering, or reading an off-piste exploration of the 20th century history of the Jewish community in Europe. Things I Didn't Throw Out is a wry and unsentimental account of the emotional and physical labour of a carer and an attempt to understand one's parent as a person with their own history, personality and temperament independent of parenthood. It is also a nuanced portrait of a woman who refused to compromise and continued to demand respect, who was sensitive to language and the complexities of history, society and politics. Some comparisons might include Helen Macdonald's H is for Hawk, Cathy Rentzenbrink's Last Act of Love and Brian Dillon's In the Dark Room.

        A Handbook of Minerals, Crystals, Rocks and Ores

        by P.O. Alexander

        The book is divided into four sections, minerals, crystals, rocks and ores. Section A incorporates nine chapterss, begins with presenting salient features of the earth--its structure and composition. The second Minerals and Mineralogy briefly tells about their diversity and their categorisation and introduces the interesting way they are named. Crystal chemistry the third is the heart and soul of mineralogy and deals in somewhat details about the building blocks of minerals -atoms and ions and the way they form diverse types of minerals are. It tries to tell why every combination of chemical compounds cannot result into a naturally occurring mineral. The fourth and fifth s deal with Properties of Minerals, physical and optical. The section describe various physical properties that are helpful in the identification both in hand specimens and as thin section under the microscope. These two s are adequately aided with a number of illustrations, photographs and photomicrographs to bring home the point. five deals with classification of minerals and their occurrence and forms a prelude to the next two s on descriptive mineralogy. Important silicate and non silicate minerals are described in s eight and nine. A brief description of mineral uses is dealt with in both descriptive mineralogy as well Section D on mineral deposits, however, the last , Mineral uses presents an overall picture and will be interesting as well as educating to students and even general reader. Section B is devoted to crystals and crystallography. one introduces the subject while two presents basic crystallographic elements. three deals with the main six crystals systems while also giving a preliminary idea about stereographic projection and x-ray crystallography. Section C covers petrology, beginning with introduction to science of petrology, rock nomenclature. two is devoted to the study of igneous rocks, including their forms, composition, textures, structures, classification and description. Sedimentary rocks is the theme of three while different aspects of metamorphic rocks including kinds and agents of metamorphism and classification and description of metamorphism. The last portion of this also considers metamorphism in the background of global tectonics. five, the rock cycle presents a concise summary of geological events that have shaped the planet earth. The last section D is what geology is all about for a man on the street and its significance in nation building--the Ore minerals. It begins with what ore is and its place in human affairs as a well as presenting the important terminology in economic geology. two deals with ore genesis and presents various hypogene and supergene process that carves out ore deposits from non economic materials. three, mineral deposits and global tectonics is becoming a very popular theme among the earth scientists. A brief introduction of the same will be certainly appreciated by the student community and prompt them for further study in this direction. A general survey of Indias mineral resources is the theme of four. It covers almost all of the commonly used ores, metallic, non metallic or fuels. The last of section D and the boom, Indian mineral industry: some facts and figures will present where our country stands in the realm of mineral resources. Latest available data of resources, production, export, import, organisations that matter and other useful facts and figures are presented.
