  John Wesley Powell was a pioneer American explorer, ethnologist, and geologist in the 19th Century. He set out to explore the Colorado and the Grand Canyon. He gathered nine men, four boats and food for ten months and set out from Green River, Wyoming. Passing through dangerous rapids, the group passed down the Green River to its confluence with the Colorado River (then also known as the Grand River upriver from the junction), near present-day Moab, Utah.The expedition's route traveled through the Utah canyons of the Colorado River, which Powell described in his published diary as having …wonderful features—carved walls, royal arches, glens, alcove gulches, mounds and monuments. From which of these features shall we select a name? We decide to call it Glen Canyon. One man (Goodman) quit after the first month and another three (Dunn and the Howland brothers) left at Separation Rapid in the third, only two days before the group reached the mouth of the Virgin River after traversing almost 1,500 km. Powell retraced the route with another expedition, producing photographs, an accurate map, and various papers, including ethnographic reports of the area's Native Americans and a monograph on their languages.

  Rethinking Urban Parks - Public...

  A study of public recreation space and how urban developers can encourage ethnic diversity through planning that supports multiculturalism.   Urban parks such as New York City’s Central Park provide vital public spaces where city dwellers of all races and classes can mingle safely while enjoying a variety of recreations. By coming together in these relaxed settings, different groups become comfortable with each other, thereby strengthening their communities and the democratic fabric of society. But just the opposite happens when, by design or in ignorance, parks are made inhospitable to certain groups of people.   This pathfinding book argues that cultural diversity should be a key goal in designing and maintaining urban parks. Using case studies of New York City’s Prospect Park, Orchard Beach in Pelham Bay Park, and Jacob Riis Park in the Gateway National Recreation Area, as well as New York’s Ellis Island Bridge Proposal and Philadelphia's Independence National Historical Park, the authors identify specific ways to promote, maintain, and manage cultural diversity in urban parks. They also uncover the factors that can limit park use, including historical interpretive materials that ignore the contributions of different ethnic groups, high entrance or access fees, park usage rules that restrict ethnic activities, and park “restorations” that focus only on historical or aesthetic values. With the wealth of data in this book, urban planners, park professionals, and all concerned citizens will have the tools to create and maintain public parks that serve the needs and interests of all the public.

  In this book, you will learn about cannabis from its fundamental unit, in other words, what identifies it and gives it these important characteristics, making it a unique species, based on its genetic material or the information present in the plant's genes. This network of DNA (deoxyribonucleic acid) and RNA (ribonucleic acid), controls all the processes of defense, nutrition, and communication of cannabis, and at the same time produces wonderful molecules such as phenylpropanoids, cannabinoids, and terpenes, which offer us important medicinal properties. 
  New sequencing technologies have allowed a deeper study of the Cannabis genome and thanks to this, more important proteins for the plant are now known, as well as the biological pathways where they act, allowing plant species to be genetically modified, providing great benefits for crops.  
  Additionally, genetic engineering is transforming agricultural techniques, being a useful alternative in monitoring the stages of cultivation, also, these advances are revolutionizing the understanding of pharmacogenetics, which is how our body assimilates cannabis-based medicines. 
  If you are interested in learning more about the extraordinary world of cannabis genetics, we invite you to enjoy this audiobook that Pharmacology University brings to you.

  Fluoride: Drinking Ourselves to...

  Fluoride is more toxic than lead, yet it is routinely added to the drinking water of Ireland and Britain. In Fluoride: Drinking Ourselves to Death?, Barry Groves presents an array of convincing and persuasive arguments that dismantle the commonly held belief that the fluoridation of water is beneficial to our health.
  
  The fluoridation of water has been used for the prevention of tooth decay for over fifty years. During this time little research has been done to ascertain whether it works. The chemicals used are classified as toxic industrial waste, yet no study has ever been conducted into their safety for human consumption.
  
  At the same time, research has uncovered serious side effects including death, cancer, skeletal fluorosis, osteoporosis, dementia, lowered IQ, kidney damage and even increased dental decay. Fluoride is only slightly less toxic than arsenic and all the evidence points incontrovertibly to the harm caused by fluoride to human, plant and animal life. Yet it is routinely added to the drinking water of five million people in Britain and more than two and a half million people in Ireland.
  
  Strongly opposed throughout the world, water fluoridation is far less widely accepted than its proponents would have us believe. Only two percent of the people of Western Europe have their water fluoridated — almost all of them within Britain and Ireland. Despite this, dental organisations lobby governments to compel everyone to ingest fluoride, whether they want it or not and without regard to possible harm.
  
  The vast majority of dentists maintain that the fluoridation of water is not debatable. In this book, Barry Groves assembles evidence to refute every single argument made by the dental establishment in favour of fluoridation. This carefully researched and persuasively written book demonstrates that the case for fluoridation of water is based on poor science and dogmatic ignorance rather than on any scientifically proven benefit to public health. His conclusions are truly alarming for everyone concerned with their own health, that of their families and of society in general.

  “This exciting saga crosses space and time to illustrate how humans, born of stardust, were shaped—and how they in turn shaped the world we know today.” —Publishers Weekly   This book offers “world history on a grand scale”—pulling back for a wider view and putting the relatively brief time span of human history in context. After all, our five thousand years of recorded civilization account for only about one millionth of the lifetime of our planet (Kirkus Reviews).  Big History interweaves different disciplines of knowledge, drawing on both the natural sciences and the human sciences, to offer an all-encompassing account of history on Earth. This new edition is more relevant than ever before, as we increasingly grapple with accelerating rates of change and, ultimately, the legacy we will bequeath to future generations. Here is a path-breaking portrait of our world, from the birth of the universe from a single point the size of an atom to life on a twenty-first-century planet inhabited by seven billion people.

  Mount Sinai

  This study of the Egyptian mountain widely believed to be Mount Sinai examines its geographical features, sacred sites, and the effects of rising tourism.   Amid the high mountains of Egypt's southern Sinai Peninsula stands Jebel Musa, “Mount Moses,” which many Christians and Muslims revere as Mount Sinai. In this fascinating study, Joseph Hobbs draws on geography and archaeology, Biblical and Quranic accounts, and a wide array of personal experiences—from Christian monks to Bedouin shepherds, medieval Europeans, and casual tourists—to explore why this mountain came to be considered a sacred place. He also shows how that very perception now threatens its fragile ecology and inspiring solitude.   After discussing the physical and geographic characteristics of Jebel Musa that suggest it as the most probable Mount Sinai, Hobbs fully describes all Christian and Muslim sacred sites around the mountain. He also views Mount Sinai from the perspectives of the Jabaliya Bedouins and the monks of the St. Katherine Monastery, both of whom have inhabited in the region for centuries.   Hobbs concludes his account with the international debate over whether to build a cable car on Mount Sinai and with an unflinching description of the negative impact of tourism on the delicate desert environment. His book raises important, troubling questions for everyone concerned about the fate of the earth's wild and sacred places.
