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
When we approach such men as St. Bernard of Clairvaux and John Calvin, we are approaching two men who were not only significant figures of their time but figures standing on opposite shorelines of the influence and impact of Scholasticism, as well as a tumultuous decline in orthodoxy. Despite this reality, what is most compelling about these two men is the continuity of their developed thought, even though they were worlds apart, separated by time. This continuity is most assuredly grounded in their historical sources, and, more importantly, their faithful handling of God’s word. That continuity, although not point for point, was rather for the significant part of the structure and content—sum and substance—of the twofold knowledge of God and self. For both of these men, this doctrine was fundamental, permeating the whole of their world and life philosophy. Bernard and Calvin clearly saw the implications of this twofold knowledge. These implications manifest in the realm of various doctrines and the network of their system of thought. This book seeks to explore those various components of their twofold knowledge of God and self, as well as the implications in the realm of experiential Christianity.

Book Description
On October 29, 1908, a party of four men, led by Ernest Shackleton, set out to be the first to reach the South Pole. Three months later, their mission was in ruins and they faced certain death if they carried on. Just ninety-seven miles from the South Pole, Shackleton turned back. One hundred years later, in October 2008, a team that included descendants of that original party, led by Henry Worsley, set out from Shackleton’s hut to celebrate the centenary of his expedition by retracing the exact 870-mile route and going on to finish the last ninety-seven miles. This captivating book explores the history of the original expedition and reasons behind its failure, while capturing the meticulous planning, fundraising, and training for the new expedition. It includes riveting accounts of the team’s first days on the ice, Christmas on the polar plateau, the brutal reality of crossing the Beardmore Glacier, and the final miles to the South Pole. In Shackleton's Footsteps is a unique story of adventure, pioneering spirit, settling old family business, and man’s triumph over nature.

Book Description
Long ago we humans used a form of communication and sensing that did not involve the brain in any way; rather, it came from a sacred place within our hearts. What good would it do to find this place again? This is a book of remembering. You have always had this place within your heart, and it is still there now. It existed before creation, and it will exist even after the last star shines its brilliant light. At night when you enter your dreams, you leave your mind and enter the sacred space of your heart. But do you remember? Or do you only remember the dream? Why am I telling you about this "something" that is fading from our memories? What good would it do to find this place again in a world where the greatest religion is science and the logic of the mind? Don't I know where emotions and feelings are second-class citizens? Yes, I do. But my teachers have asked me to remind you who you really are. You are more than just a human being, much more. For within your heart is a place, a sacred place, where the world can literally be remade through conscious cocreation. If you really want peace of spirit and if you want to return home, I invite you into the beauty of your own heart. With your permission, I will show you what has been shown to me. I will give you the exact instructions to the pathway into your heart where you and God are intimately one. It is your choice. But I must warn you: Within this experience resides great responsibility. Life knows when a spirit is born to the higher worlds, and life will use you as all the great masters who have ever lived have been used. If you read this book and do the meditation and then expect nothing to change in your life, you may get caught spiritually napping. Once you have entered the light of the great darkness, your life will change -- eventually, you will remember who you really are.

Book Description
#1 NEW YORK TIMES BESTSELLER • In her latest book, Brené Brown writes, “If we want to find the way back to ourselves and one another, we need language and the grounded confidence to both tell our stories and be stewards of the stories that we hear. This is the framework for meaningful connection.” Don’t miss the five-part HBO Max docuseries Brené Brown: Atlas of the Heart! In Atlas of the Heart, Brown takes us on a journey through eighty-seven of the emotions and experiences that define what it means to be human. As she maps the necessary skills and an actionable framework for meaningful connection, she gives us the language and tools to access a universe of new choices and second chances—a universe where we can share and steward the stories of our bravest and most heartbreaking moments with one another in a way that builds connection. Over the past two decades, Brown’s extensive research into the experiences that make us who we are has shaped the cultural conversation and helped define what it means to be courageous with our lives. Atlas of the Heart draws on this research, as well as on Brown’s singular skills as a storyteller, to show us how accurately naming an experience doesn’t give the experience more power—it gives us the power of understanding, meaning, and choice. Brown shares, “I want this book to be an atlas for all of us, because I believe that, with an adventurous heart and the right maps, we can travel anywhere and never fear losing ourselves.”

Book Description
A vision to address our environment, economy, politics, culture, and to catalyze the radical whole-system change we need now Recasting current problems as emergent opportunities, Terry Patten offers creative responses, practices, and conscious conversations for tackling the profound inner and outer work we must do to build an integral future. In practical and personal terms, he discusses how we can all become active agents of a transformation of human civilization and why that is necessary to our continued survival. Patten's narrative focuses on two aspects of existence--our dynamic but fractured and threatened world, and our underlying wholeness and unity. Only by honoring both of these realities simultaneously can we make sustainable changes in ourselves, our communities, our body politic, and our planetary life-support system. A New Republic of the Heart provides a comprehensive understanding and inspiring vision for "being the change" in a way that can address the most intractable problems of our time. Patten shows how we can come together in our communities for conversations that matter and describes new communities, enterprises, and forms of dialogue that integrate both inner personal growth work with outer awareness, activism, and service.

Book Description
Research centering on blood flow in the heart continues to hold an important position, especially since a better understanding of the subject may help reduce the incidence of coronary arterial disease and heart attacks. This book summarizes recent advances in the field; it is the product of fruitful cooperation among international scientists who met in Japan in May, 1990 to discuss the regulation of coronary blood flow.
