The hypothesis of this research was that by stretching microfiltration or ultrafiltration membranes, their performance, in terms of flux and rejection, could be improved. Stretching a membrane was envisioned to stretch its pores, or change the aspect ration of the pores. It was thought that changing the aspect ratio could lead to improved flux (by increasing the pore area) while also improving the rejection of particles (by decreasing the length of the minor axis). The objective of this research was to study the effects of uniaxial stretching of microporous membranes (and thereby change the aspect ratio) on their performance (measured in terms of flux and particle rejection).
How did British authorities manage to secure the commitment of large dominion and Indian armies that could plan, fight, shoot, communicate, and sustain themselves, in concert with the British Army and with each other, during the era of the two world wars? What did the British want from the dominion and Indian armies and how did they go about trying to get it? Douglas E Delaney seeks to answer these questions to understand whether the imperial army project was successful. Answering these questions requires a long-term perspective — one that begins with efforts to fix the armies of the British Empire in the aftermath of their desultory performance in South Africa (1899-1903) and follows through to the high point of imperial military cooperation during the Second World War. Based on multi-archival research conducted in six different countries, on four continents, Delaney argues that the military compatibility of the British Empire armies was the product of a deliberate and enduring imperial army project, one that aimed at standardizing and piecing together the armies of the empire, while, at the same time, accommodating the burgeoning autonomy of the dominions and even India. At its core, this book is really about how a military coalition worked.
In 1936, long before the discovery of the Viking settlement at L'Anse aux Meadows, the Royal Ontario Museum made a sensational acquisition: the contents of a Viking grave that prospector Eddy Dodd said he had found on his mining claim east of Lake Nipigon. The relics remained on display for two decades, challenging understandings of when and where Europeans first reached the Americas. In 1956 the discovery was exposed as an unquestionable hoax, tarnishing the reputation of the museum director, Charles Trick Currelly, who had acquired the relics and insisted on their authenticity. Drawing on an array of archival sources, Douglas Hunter reconstructs the notorious hoax and its many players. Beardmore unfolds like a detective story as the author sifts through the voluminous evidence and follows the efforts of two unlikely debunkers, high-school teacher Teddy Elliott and government geologist T.L. Tanton, who find themselves up against Currelly and his scholarly allies. Along the way, the controversy draws in a who’s who of international figures in archaeology, Scandinavian studies, and the museum world, including anthropologist Edmund Carpenter, whose mid-1950s crusade against the find’s authenticity finally convinced scholars and curators that the grave was a fraud. Shedding light on museum practices and the state of the historical and archaeological professions in the mid-twentieth century, Beardmore offers an unparalleled view inside a major museum scandal to show how power can be exercised across professional networks and hamper efforts to arrive at the truth.
Our Renewable Energy Future delves into the clean energy technology evolution and where our energy system is going.

This book is a culmination of Dr Arent's lifelong passion for energy, sustainable development, and renewable energy technology. It covers the journey of evolving technology, economics, political economy and geopolitics of clean energy over the last 40 years and provides insights for the coming decades. From a technology perspective, the book traces the arc of recent innovations and synthesizes innovations across multiple interacting perspectives into a description of Our Renewable Energy Future.
Published to coincide with the centennial celebration of U.S. Navy Aviation, this book chronicles Navy aviation from its earliest days, before the Navy’s first aircraft carrier joined the fleet, through the modern jet era marked by the introduction of the F-18 Hornet. It tells how naval aviation got its start, profiles its pioneers, and explains the early bureaucracy that fostered and sometimes inhibited its growth. The book then turns to the refinement of carrier aviation doctrine and tactics and the rapid development of aircraft and carriers, highlighting the transition from propeller-driven aircraft to swept wing jets in the period after WW II. Land-based Navy aircraft, rotary-wing aircraft and rigid airships, and balloons are also considered in this sweeping tribute.

At last count, nearly 2,400 people can claim that their lives were saved by a U.S. submarine during World War II. Of that number, 523 Allied aviators could claim that distinction after crashing their aircraft into the sea and being saved by a submarine operating in the "Lifeguard League." The remaining number were a collection of other military and civilian personnel, each with a story to tell and now able to tell their grand-children. Some of those rescued went on to retire as senior military officers including U.S. Navy Admirals, some back to missionary work, some to manage large companies in later years, some to philanthropic endeavors to pay everyone back for saving their lives. Appendix A is an intensely-researched index of nearly 2,200 names of those saved.

At last count, more than 80 U.S. submarines recorded some type of actual "friendly fire" incident in which they were involved during their WWII war patrols. From being attacked by Allied bombers, depth-charged by U.S. ships or fired upon by armed Allied merchant ships, submariners quickly came to understand the bitter truth of the maxim: 'The submarine has no friends.' While the majority of submarines and their crew escaped with little more than bruised egos or minor injuries, three submarines and their crews were lost to friendly fire. For the first time in book format, a serious and most comprehensive research effort has gone into capturing all such "friendly fire" incidents involving U.S. submarines during World War II. Compiled through relentless research by the co-authors, their stories of loss and survival by "other than the enemy" is presented within these pages.
