Longtime science fiction writers Rob Chilson and William F. Wu collaborated on these ten stories, all of which first appeared in Analog Science Fiction and Fact magazine. Chilson is especially known for his work in Analog, as is Wu, a finalist for multiple Hugo and Nebula awards. This collection is enhanced by their light-hearted, informative introduction and afterwords to each story. ~~~~~ Excerpt ~~~~~ Roger was dozing in his seat when he felt the familiar small hands and bony knees of his daughter climbing into his lap. He opened his eyes and put one arm around her; she, in turn, had one firm arm around Buffalo Bill?s neck. ?Hi, sweetie,? he said, his voice hoarse. ?Something the matter?? Marta looked solemnly out into the starry night. The car seemed to be hovering motionless in the sky. A strange black sky, with no ground visible. Earth was invisible far below them; it could not be seen through any of their windows. They had flown out of the shadow of Earth, thrown by their retained rotational velocity. Now Roger would keep the sun under them, charge the hull with electricity to ward off the solar wind, and pray. The thermo-electric elements kept the car cool enough, but the floor and walls were warm to the touch. The windows were edged with flame from the sunlight below. ?Where are we?? Marta asked. Roger cleared his throat. ?We?re nearly halfway to the moon, sweetie.? Luna was visible off to the right, as if on the horizon. ?Oh.? She considered the stars thoughtfully. Finally, unexpectedly, she asked, ?Are we going to be like the tigers?? Startled, Roger laughed. ?Sure. You like that one?? He used a light tone, to see if she would turn playful. Marta nodded, meeting his gaze solemnly. Sobering, Roger recited: ?The mind desires to roam, The soul aspires to soar, But Earth?s a fettered prison Without freedom?s ancient lore. My seeking mind turns outward To tropic jungles and the night, Where cold-eyed tigers freely prowl To hunt and dream and smite.? Marta said sleepily, ?It?s always night out here,? and touched her nose to his. He kissed her cheek. ?Do you know one about buffaloes?? she asked, cuddling. ?Uh, yeah, I know a song about where buffalo roam. Or used to, at least. Shall I teach it to you?? ?Yeah!? ?Okay.? Roger paused to get the lyrics straight and as he did, he reflected that buffaloes had been confined to zoos and parks even longer than tigers. ?Oh, give me a home?.? As he sang and cuddled his daughter, Roger brooded over his position and course. He had been brooding over the course for days. They were approaching turnover time for travel to the Moon or Ell Clusters, and still piling on gee. Luna, of course, was nowhere near his line of flight. He would pass near the L-4 Cluster as space distances go, but it would scarcely be visible. The transponder had beeped occasionally? it sounded off audibly when tweaked by questing beams, even as it responded. Now Roger shut off its responses. To have come out without filing a flight plan or with a silent transponder would have been a giveaway; the Patrol would have been all over him at once. Now, though, maybe he had left it on too long. As it was, the transponder had beeped every fifteen minutes or so since he had first been warned of his deviation from his LEO destination. They knew where he was, how fast he was accelerating, and in what direction. Where were they? Roger hugged his daughter, sang louder as she joined in the chorus. He couldn?t help glancing around at all the windows, expecting to see the prow of a CisLunar Patrol ship, evil menace incarnate, loom near them. If they caught him, he would lose his daughter. He could think of nothing else to do. He could only run.

Cancer is an incredibly diverse and difficult disease to treat, and even after decades of research there is no definitive cure. Therefore, it is highly crucial to search for novel and new organic molecules with high potency, low toxicity, and low mutagenicity with selective anticancer properties that are able to overcome frequently developed resistance to available drugs. Heterocyclic anticancer agents are an important class of drugs for cancer therapies. This book explores different heterocycles and their use as anticancer therapies. Topics covered include different heterocyclic derivatives, the impact of heterocycles on anticancer agent development, and naturally occurring heterocycles.

In this radical reassessment, Alun Munslow challenges conventional notions of history and offers a new vision of historical thinking and practice. Deploying a range of concepts such as scepticism, aesthetics, ethics, standpoint, irony, authorship and a new understanding of truth, The Future of History examines history as a form of knowledge in itself, arguing that in the future the multiple forms of its expression will be as significant as its content. This thought-provoking, challenging and unique book offers a way forward for history after postmodernism and is essential reading for anyone asking the question 'what is history?'.

The handbook provides an understanding of consolidated processing and biorefinery systems for the production of bio-based chemicals and value-added bioproducts from renewable sources. The chapters look at a variety of bioenergy technological advances and improvements in the energy and materials sectors that aim to lower our dependence of fossil fuels and consequently reduce greenhouse gas (GHG) emissions. The volume looks at a selection of processes for the production of energy and biomaterials, including the Fischer–Tropsch process, gasification, pyrolysis, combustion, fermentation from renewable sources (such as, plants, animals and their byproducts), and others. Applications that are explored include transportation fuels, biodiesel production, wastewater treatment, edible packaging, bioplastics, physical rehabilitation, tissue engineering, biomedical applications, thermal insulation, industrial value compounds, and more. All of the topics covered in this publication address consolidated processes that play a pivotal role in the production of bioenergy and biomaterials because these processes require fewer unitary operations needed in the process, leading to a more direct method of production. This type of production system contributes to decreasing negative effects on the environment, lowering costs, saving energy and time, and improving profitability and efficiency. This volume will be valuable for the industrial sector, for researchers and scientists, as well as for faculty and advanced students.

Everyone is becoming more environmentally conscious and therefore, chemical processes are being developed with their environmental burden in mind. This also means that more traditional chemical methods are being replaced with new innovations and this includes new solvents. Solvents are everywhere, but how necessary are they? They are used in most areas including synthetic chemistry, analytical chemistry, pharmaceutical production and processing, the food and flavour industry and the materials and coatings sectors. However, the principles of green chemistry guide us to use less of them, or to use safer, more environmentally friendly solvents if they are essential. Therefore, we should always ask ourselves, do we really need a solvent? Green chemistry, as a relatively new sub-discipline, is a rapidly growing field of research. Alternative solvents - including supercritical fluids and room temperature ionic liquids - form a significant portion of research in green chemistry. This is in part due to the hazards of many conventional solvents (e.g. toxicity and flammability) and the significant contribution that solvents make to the waste generated in many chemical processes. Solvents are important in analytical chemistry, product purification, extraction and separation technologies, and also in the modification of materials. Therefore, in order to make chemistry more sustainable in these fields, a knowledge of alternative, greener solvents is important. This book, which is part of a green chemistry series, uses examples that tie in with the 12 principles of green chemistry e.g. atom efficient reactions in benign solvents and processing of renewable chemicals/materials in green solvents. Readers get an overview of the many different kinds of solvents, written in such a way to make the book appropriate to newcomers to the field and prepare them for the 'green choices' available. The book also removes some of the mystique associated with 'alternative solvent' choices and includes information on solvents in different fields of chemistry such as analytical and materials chemistry in addition to catalysis and synthesis. The latest research developments, not covered elsewhere, are included such as switchable solvents and biosolvents. Also, some important areas that are often overlooked are described such as naturally sourced solvents (including ethanol and ethyl lactate) and liquid polymers (including poly(ethyleneglycol) and poly(dimethylsiloxane)). As well as these additional alternative solvents being included, the book takes a more general approach to solvents, not just focusing on the use of solvents in synthetic chemistry. Applications of solvents in areas such as analysis are overviewed in addition to the more widely recognised uses of alternative solvents in organic synthesis. Unfortunately, as the book shows, there is no universal green solvent and readers must ascertain their best options based on prior chemistry, cost, environmental benefits and other factors. It is important to try and minimize the number of solvent changes in a chemical process and therefore, the importance of solvents in product purification, extraction and separation technologies are highlighted. The book is aimed at newcomers to the field whether research students beginning investigations towards their thesis or industrial researchers curious to find out if an alternative solvent would be suitable in their work.
