While the battle over integration rages around them, Lucy Conyers of Tallahassee befriends the family of her maid, who lives on the other side of the tracks in a racially divided city.

The first book in the stunning Blood of the Lamb trilogy, full of action, suspense and drama. The Crossing is the first book in a stunning trilogy that follows the fate of Maryam and her unlikely companions - Joseph, Ruth and Lazarus. This is fast, suspenseful drama underpinned by a powerful and moving story about love and loss. The people of Onewere, a small island in the Pacific, know that they are special - chosen to survive the deadly event that consumed the Earth. Now, from the rotting cruise ship Star of the Sea, the elite control the population - manipulating old texts to set themselves up as living 'gods'. But what the people of Onewere don't know is this: the leaders will stop at nothing to meet their own blood-thirsty needs... When Maryam crosses from child to woman, she must leave everything she has ever known and make a crossing of another kind. But life inside the ship is not as she had dreamed, and she is faced with the unthinkable: obey the leaders and very likely die, or turn her back on every belief she once held dear. 'Like 1984 for teenagers - direct, passionate and powerful' - Margaret Mahy. Winner of the NZ Post Book Award for YA fiction 2010.

An Australian handbook to support the safe administration of blood and blood products by health professionals at the patient's side.

The placenta is an organ that connects the developing fetus to the uterine wall, thereby allowing nutrient uptake, waste elimination, and gas exchange via the mother's blood supply. Proper vascular development in the placenta is fundamental to ensuring a healthy fetus and successful pregnancy. This book provides an up-to-date summary and synthesis of knowledge regarding placental vascular biology and discusses the relevance of this vascular bed to the functions of the human placenta.

This e-book will review special features of the cerebral circulation and how they contribute to the physiology of the brain. It describes structural and functional properties of the cerebral circulation that are unique to the brain, an organ with high metabolic demands and the need for tight water and ion homeostasis. Autoregulation is pronounced in the brain, with myogenic, metabolic and neurogenic mechanisms contributing to maintain relatively constant blood flow during both increases and decreases in pressure. In addition, unlike peripheral organs where the majority of vascular resistance resides in small arteries and arterioles, large extracranial and intracranial arteries contribute significantly to vascular resistance in the brain. The prominent role of large arteries in cerebrovascular resistance helps maintain blood flow and protect downstream vessels during changes in perfusion pressure. The cerebral endothelium is also unique in that its barrier properties are in some way more like epithelium than endothelium in the periphery. The cerebral endothelium, known as the blood-brain barrier, has specialized tight junctions that do not allow ions to pass freely and has very low hydraulic conductivity and transcellular transport. This special configuration modifies Starling's forces in the brain microcirculation such that ions retained in the vascular lumen oppose water movement due to hydrostatic pressure. Tight water regulation is necessary in the brain because it has limited capacity for expansion within the skull. Increased intracranial pressure due to vasogenic edema can cause severe neurologic complications and death.

This volume discusses the current state of the nation's blood supply--including studies of blood availability, ways of enhancing blood collection and distribution, frozen red cell technology, logistical concerns in prepositioning frozen blood, extended liquid storage of red cells, and blood substitutes.
