Histochemistry: An Explanatory Outline of Histochemistry and Biophysical Staining describes the histochemical staining of cells and tissues as a major tool applied in biological and medical investigations, both in basic research and in practical applications such as clinical diagnosis. The book may be considered as a guide to understanding the scientific basis of staining procedures and alternate actions to take when common methods do not proceed as expected. The first chapter gives general theoretical ideas from which most part of the book is largely organized around. As the book considers the arts and crafts making up the practice of histochemistry and biological staining, emphasis is give...
The Paper Time Machine is a book that will change the way you think about the past.It contains 130 historical black-and-white photographs, reconstructed in colour and introduced by Wolfgang Wild – creator and curator of the Retronaut website. The site has become a global phenomenon, collecting images that collapse the distance between the past and present and tear a hole in our map of time. The Paper Time Machine goes even further. Early photographic technology lacked a crucial ingredient – colour. As early as the invention of the medium, skilled artisans applied colour to photographs by hand, attempting to convey the vibrancy and immediacy of life in vivid detail. In most cases this was...
British chemistry has traditionally been depicted as a solely male endeavour. However, this perspective is untrue: the allure of chemistry has attracted women since the earliest times. Despite the barriers placed in their path, women studied academic chemistry from the 1880s onwards and made interesting or significant contributions to their fields, yet they are virtually absent from historical records.Comprising a unique set of biographies of 141 of the 896 known women chemists from 1880 to 1949, this work attempts to address the imbalance by showcasing the determination of these women to survive and flourish in an environment dominated by men. Individual biographical accounts interspersed with contemporary quotes describe how women overcame the barriers of secondary and tertiary education, and of admission to professional societies. Although these women are lost to historical records, they are brought together here for the first time to show that a vibrant culture of female chemists did indeed exist in Britain during the late 19th and early 20th centuries./a
Seventeen-year-old Quinn Hughes needs to be in top shape if she wants to medal at the swimming World Championships in ten months. This means no easy distractions, no matter how pretty they are. She’s still piecing her confidence back together after not qualifying for the Olympics, her relationship with her twin brother is getting worse the more he hangs out with the popular kids, and then Kennedy Reed suddenly squeezes herself back into Quinn’s life. The girl who was her best friend. The girl who gave Quinn her first kiss. The girl who hasn’t spoken to her since. Soon, Quinn finds herself juggling her new girlfriend, training for the biggest competition of her life, and discovering she’s not the only Hughes twin with a crush on Kennedy Reed. All these distractions are getting to her, and if she wants that medal she needs to find a way to stop drowning on dry land.
It is highly probable that the ability to distinguish between living and nonliving objects was already well developed in early prehuman animals. Cognizance of the difference between these two classes of objects, long a part of human knowledge, led naturally to the division of science into two categories: physics and chemistry on the one hand and biology on the other. So deep was this belief in the separateness of physics and biology that, as late as the early nineteenth century, many biologists still believed in vitalism, according to which living phenomena fall outside the confines of the laws of physics. It was not until the middle of the nineteenth century that Carl Ludwig, Hermann von He...
there are two sides to every breakup. This is Jordan and Courtney, totally in love. Sure, they were an unlikely high school couple. But they clicked; it worked. They're even going to the same college, and driving cross-country together for orientation. Then Jordan dumps Courtney -- for a girl he met on the Internet. It's too late to change plans, so the road trip is on. Courtney's heartbroken, but figures she can tough it out for a few days. La la la -- this is Courtney pretending not to care. But in a strange twist, Jordan cares. A lot. Turns out, he's got a secret or two that he's not telling Courtney. And it has everything to do with why they broke up, why they can't get back together, and how, in spite of it all, this couple is destined for each other.
