Gasoline Compression Ignition Technology: Future Prospects by Gautam Kalghatgi, Avinash Kumar Agarwal, Harsh Goyal, Moez Ben Houidi
Requirements: .PDF reader, 13 MB
Overview: This book focuses on gasoline compression ignition (GCI) which offers the prospect of engines with high efficiency and low exhaust emissions at a lower cost. A GCI engine is a compression ignition (CI) engine which is run on gasoline-like fuels (even on low-octane gasoline), making it significantly easier to control particulates and NOx but with high efficiency. The state of the art development to make GCI combustion feasible on practical vehicles is highlighted, e.g., on overcoming problems on cold start, high-pressure rise rates at high loads, transients, and HC and CO emissions. This book will be a useful guide to those in academia and industry.

Biomass Utilization: Conversion Strategies by Nhuan Phu Nghiem, Tae Hyun Kim, Chang Geun Yoo
Requirements: .PDF reader, 5.7 MB
Overview: This book focuses on the technologies developed for the conversion of all three biomass components, i.e. cellulose, hemicellulose and lignin, and their constituents, to fuels and high-value products. Both biochemical and thermochemical approaches are reviewed. Additionally, the developed technologies are described in detail and their potential applications as well as their commercial status are discussed.
The early attempts to produce fuel ethanol from lignocellulosic biomass feedstock focused solely on the biological conversion of cellulose because the only organism that had been used successfully for commercial production of ethanol, i.e. Saccharomyces cerevisiae, could only ferment glucose, which was obtained from the hydrolysis of cellulose. Hemicellulose and lignin were considered as wastes in these processes and were normally removed in pretreatment processes to enhance enzymatic hydrolysis of the remaining cellulose.
However, this approach was not economically feasible and as a result, the biorefinery concept was developed. In a biorefinery, in addition to ethanol, various higher-value products are produced from hemicellulose and lignin, which were previously not considered. Consequently, technologies were developed for the fractionation of biomass and conversion of hemicellulose and lignin to fuels and high-value products to improve the economic feasibility.
Written and edited by a team of investigators with many years of experience in biomass processing research and development, this book is an informative resource for postgraduate students and researchers interested in biorefinery and biofuel technologies both in academia- and commercial laboratories.

A Spy Like Me: Six Days. Three Agents. One Chance to Find James Bond (Double O, #2) by Kim Sherwood / Narrated by Pippa Bennett-Warner
Requirements: .MP3 player, 303 mb
Overview: An elite team of MI6 agents must go undercover to unravel a smuggling network funding violent terror in the second thrilling adventure in the acclaimed Double O series by Kim Sherwood.

James Bond is alive.

Or at least, he was when he left a clue at the black site where the insidious private military company Rattenfänger held him captive. MI6 cannot spare any more lives attempting to track down one missing agent—no exceptions, even for Bond. But Johanna Harwood, 003, has her own agenda. Sidelined by her superiors while she grieves the loss of a loved one, Harwood goes on an unsanctioned mission: to find 007. Meanwhile, MI6 has another problem…

A bomb has detonated in London.

Double O agents on the trail of the terrorists responsible acted quickly to prevent mass destruction and save lives. But MI6 failed to neutralize the nation’s enemies before they could strike, and one of their own was seriously injured in the blast.

They won’t fail again.

Assigned to root out the source of the terrorists’ funding, Joseph Dryden, 004, and Conrad Harthrop-Vane, 000, enter the field. Tracing clues from Sotheby’s auction house to Crete to Venice, they uncover a money laundering scheme involving diamonds, black market antiquities, and human trafficking. Once a major sale is made, a six-day countdown to the next terror attack begins. As the Double O’s follow the twisting trail, they find themselves unexpectedly inching closer to Bond…

Hemicellulose Biorefinery: A Sustainable Solution for Value Addition to Bio-Based Products and Bioenergy by Michel Brienzo
Requirements: .PDF reader, 13.9 MB
Overview: This edited book provides knowledge about hemicelluloses biorefinery approaching production life cycle, circular economy, and valorization by obtaining value-added bioproducts and bioenergy. A special focus is dedicated to chemical and biochemical compounds produced from the hemicelluloses derivatives platform. Hemicelluloses are polysaccharides located into plant cell wall, with diverse chemical structures and properties. It is the second most spread organic polymer on nature and found in vast lignocellulosic materials from agro and industrial wastes, therefore, hemicelluloses are considered as abundant and renewable raw material/feedstock. Biorefinery concept contributes to hemicelluloses production associated with biomass industrial processes. Hemicelluloses are alternative sources of sugars for renewable fuels and as platform for chemicals production. This book reviews chemical processes for sugar production and degradation, obtaining of intermediate and final products, and challenges for pentose fermentation. Aspects of hemicelluloses chain chemical and enzymatic modifications are presented with focus on physicochemical properties improvement for bioplastic and biomaterial approaches. Hemicelluloses are presented as sources for advanced materials in biomedical and pharmaceutical uses, and as hydrogel for chemical and medicine deliveries. An interdisciplinary approach is needed to cover all the processes involving hemicelluloses, its conversion into final and intermediate value-added compounds, and bioenergy production. Covering this context, this book is of interest to teachers, students, researchers, and scientists dedicated to biomass valorization. This book is a knowledge source of basic aspects to advanced processing and application for graduate students, particularly. Besides, the book serves as additional reading material for undergraduate students (from different courses) with a deep interest in biomass and waste conversion, valorization, and chemical products from hemicelluloses
