Book Description
A mother wakes to a nightmare and is thrust into a race to save three lives. Rose thought she had it all, then she discovered her husband's hidden life. The revelation crushed Rose, and the breakup shattered her family. Battling through heartbreak and betrayal, she thought the worst was behind her, but nothing could prepare Rose for what came next. In this raw and confronting story, we follow three years in Rose's life. With a rare honesty, she reveals the painful emotions of a mother watching helplessly as her daughter battles a tormenting secret. It will push her to the edge, but just as the nightmare promises to end, Rose's family is haunted by a new and more ominous threat. Will the intense pressure tear her apart, or can she find the strength to face her demons and save the ones she loves? Carbon Under Pressure is based on real events. Rose's story is shocking, riveting and unforgettable, and what happened to her could happen to anyone. Carbon Under Pressure is the first book brought to life by Meg Heart for an author who would otherwise remain silent. 'Rose' cannot speak out under her real name due to laws that forbid the public disclosure of certain information in her story. She faced three choices: stay silent; tell a lesser story; or share the raw and real events from her life in a new way. We are proud to bring 'Rose's' story to life.

Book Description
This presentation describes various aspects of the regulation of tissue oxygenation, including the roles of the circulatory system, respiratory system, and blood, the carrier of oxygen within these components of the cardiorespiratory system. The respiratory system takes oxygen from the atmosphere and transports it by diffusion from the air in the alveoli to the blood flowing through the pulmonary capillaries. The cardiovascular system then moves the oxygenated blood from the heart to the microcirculation of the various organs by convection, where oxygen is released from hemoglobin in the red blood cells and moves to the parenchymal cells of each tissue by diffusion. Oxygen that has diffused into cells is then utilized in the mitochondria to produce adenosine triphosphate (ATP), the energy currency of all cells. The mitochondria are able to produce ATP until the oxygen tension or PO2 on the cell surface falls to a critical level of about 4–5 mm Hg. Thus, in order to meet the energetic needs of cells, it is important to maintain a continuous supply of oxygen to the mitochondria at or above the critical PO2 . In order to accomplish this desired outcome, the cardiorespiratory system, including the blood, must be capable of regulation to ensure survival of all tissues under a wide range of circumstances. The purpose of this presentation is to provide basic information about the operation and regulation of the cardiovascular and respiratory systems, as well as the properties of the blood and parenchymal cells, so that a fundamental understanding of the regulation of tissue oxygenation is achieved.

Book Description
The book contains a series of core auscultation “lessons”. All are case based and describe auscultation as it relates to a patient and in terms of the gold standard for interpretation of heart sounds. Auscultation is the term for listening to the internal sounds of the body, usually using a stethoscope. It is performed for the purposes of examining the circulatory system and respiratory system (heart sounds and breath sounds). As a topic it is one of the oldest in cardiology but its utility should never be underestimated. In this era of hugely expensive imaging tests, auscultation is a cornerstone of efficient diagnosis and therefore needs a fresh look. The core content of this book describes the search for diagnostic clues within patients’ heart sounds and as such this book provides superb practical advice in the form of a series of clinical pearls reflecting what accurate diagnosis with auscultation can mean to patient prognosis and outcome. This often subtle but ultimately simple subject often produces complex results and these must be considered in light of modern next-level diagnostic methods and patient management.

Book Description
“A brilliant, revisionist argument that places oil companies at the heart of 20th century history—and of the political and environmental crises we now face.” —Guardian Oil is a curse, it is often said, that condemns the countries producing it to an existence defined by war, corruption and enormous inequality. Carbon Democracy tells a more complex story, arguing that no nation escapes the political consequences of our collective dependence on oil. It shapes the body politic both in regions such as the Middle East, which rely upon revenues from oil production, and in the places that have the greatest demand for energy. Timothy Mitchell begins with the history of coal power to tell a radical new story about the rise of democracy. Coal was a source of energy so open to disruption that oligarchies in the West became vulnerable for the first time to mass demands for democracy. In the mid-twentieth century, however, the development of cheap and abundant energy from oil, most notably from the Middle East, offered a means to reduce this vulnerability to democratic pressures. The abundance of oil made it possible for the first time in history to reorganize political life around the management of something now called “the economy” and the promise of its infinite growth. The politics of the West became dependent on an undemocratic Middle East. In the twenty-first century, the oil-based forms of modern democratic politics have become unsustainable. Foreign intervention and military rule are faltering in the Middle East, while governments everywhere appear incapable of addressing the crises that threaten to end the age of carbon democracy—the disappearance of cheap energy and the carbon-fuelled collapse of the ecological order. In making the production of energy the central force shaping the democratic age, Carbon Democracy rethinks the history of energy, the politics of nature, the theory of democracy, and the place of the Middle East in our common world.

Book Description
Part green-lifestyle guide, part popular science, How Bad Are Bananas? is the first book to provide the information we need to make carbon-savvy purchases and informed lifestyle choices and to build carbon considerations into our everyday thinking. The book puts our decisions into perspective with entries for the big things (the World Cup, volcanic eruptions, the Iraq war) as well as the small (email, ironing, a glass of beer). And it covers the range from birth (the carbon footprint of having a child) to death (the carbon impact of cremation). Packed full of surprises — a plastic bag has the smallest footprint of any item listed, while a block of cheese is bad news — the book continuously informs, delights, and engages the reader. Solidly researched and referenced, the easily digestible figures, statistics, charts, and graphs (including a section on the carbon footprint of various foods) will encourage discussion and help people to make up their own minds about their consumer choices.

Book Description
It's over a year since her last diary and Laura Brown is now in her first year of university in London, a city still struggling to pull itself together in the new rationing era. Laura's right in the heart of it; her band, the dirty angels, are gigging all over town until a police crackdown on rioting students forces them out of the city. After a brief exile on her parents' farm, the angels set off in a battered VW bus on a tour of Europe with the fabulous Tiny Chainsaws in the Distance. The tour soon unravels, however, in an increasingly dramatic sequence of events that include drought in Europe and Africa, a tidal-wave of desperate immigrants, a water war in the Middle East and a city-wide face off with the army in London. Not to mention infidelity, betrayal, friendship, love and massive courage. How long can Laura distance herself from the struggle? And more importantly, how can she keep her style and hope alive in a world on the edge of madness?
