Restoring Heritage Grains : The Culture, Biodiversity, Resilience, and Cuisine of Ancient Wheats
Including recipes for baking with EinkornWheat is the most widely grown crop on our planet, yet industrial breeders have transformed this ancient staff of life into a commodity of yield and profit—witness the increase in gluten intolerance and 'wheat belly’. Modern wheat depends on synthetic fertilizer and herbicides that damage our health, land, water, and environment.Fortunately, heritage ‘landrace' wheats that evolved over millennia in the organic fields of traditional farms do not need bio-chemical intervention to yield bountifully, are gluten-safe, have rich flavor and high nutrition.Yet the robust, majestic wheats that nourished our ancestors are on the verge of extinction. In Restoring Heritage Grains, author Eli Rogosa of the Heritage Grain Conservancy, invites readers to restore forgotten wheats such as delicious gluten-safe einkorn that nourished the first Neolithic farmers, emmer—the grain of ancient Israel, Egypt, and Rome that is perfect for pasta and flatbreads, rare durums that are drought-tolerant and high in protein, and many more little known wheat species, each of which have a lineage intertwined with the human species and that taste better than any modern wheat. Restoring Heritage Grains combines the history of grain growing and society, in-depth practical advice on landrace wheat husbandry, wheat folk traditions and mythology, and guidelines for the Neolithic diet with traditional recipes for rustic bread, pastry and beer.Discover the ancient grains that may be one of the best solutions to hunger today, and provide resilience for our future.

Is a pendulum an isotope?
No, a pendulum is not an isotope. A pendulum is a weight suspended from a pivot so that it can swing freely back and forth. On the other hand, an isotope is a variant of a chemical element that has the same number of protons but a different number of neutrons in its nucleus. They are two different concepts in physics and chemistry.

Is a pendulum a isotope?
No, a pendulum is not an isotope. An isotope is a variant of a particular chemical element which has the same number of protons but a different number of neutrons. A pendulum, on the other hand, is a weight suspended from a pivot so that it can swing freely back and forth. It is a simple mechanical device used to measure time or demonstrate principles of physics.

What is the Isotope Rule?
The Isotope Rule states that atoms of the same element can have different numbers of neutrons, resulting in different isotopes of that element. Isotopes of an element have the same number of protons but different numbers of neutrons, leading to variations in atomic mass. This rule helps to explain why some elements have multiple atomic masses and why they can exist in different forms with different properties.
-
Is a simple pendulum an isotope?
No, a simple pendulum is not an isotope. An isotope is a variant of a chemical element that has the same number of protons but a different number of neutrons in its nucleus. On the other hand, a simple pendulum is a physical system consisting of a mass (bob) attached to a string or rod that swings back and forth under the influence of gravity. The two concepts are unrelated and refer to different scientific phenomena.

Western Front: Landscape, Tourism and Heritage
The Western Front has become, once again, and after 100 years, an important and increasingly popular tourist destination.The Centenary is already encouraging large numbers of visitors to engage with this highly poignant landscape of war and to commemorate the sacrifice and loss of a previous generation.Interest is also being sharpened in the 'places of war' as battle-sites, trench-systems, bunkers and mine craters gain a clearer identity as war heritage.For the first time this book brings together the three strands of heritage, landscape and tourism to provide a fresh understanding of the multi-layered nature of the Western Front.The book approaches the area as a rich dynamic landscape which can be viewed in a startling variety of ways: historically, materially, culturally, and perceptually.To illustrate these two dominant interpretations of the region's landscape - commemorative and heritage - are highlighted and their relationship to tourism explored.Tourism is a lens through which these layers can be peeled away, and each understood and interacted with according to the individual's own knowledge, motivation, and degree of emotional engagement.Tourism is not regarded here as a passive phenomenon, but as an active agent that can determine, dictate and inscribe this evocative landscape. The Western Front: Heritage, Landscape and Tourism is a timely addition to our increasing interest in the First World War and the places where it was fought.It will be indispensable to those who seek a deeper understanding of the conflict from previously undervalued perspectives.

Sustainable Marketing of Transformative Heritage Tourism
This book proposes that sustainable marketing should be founded on a higher level of consciousness, governed by the Eastern ethical principles of dharma and karma.It suggests a socially responsible, integrated marketing strategy to boost transformational heritage tourism. The book puts forward a framework to promote and inspire transformative heritage tourism from a sustainable marketing perspective.Drawing on examples from different parts of the world such as Thailand, China, the USA, India, Australia, the United Kingdom, Spain, and Hong Kong, it takes a unique approach by integrating elements associated with distributive justice, procedural justice, morally motivated existentialist authentic experiences and the well-being of visited and visiting environments.The book pivots on the planning and marketing of heritage of communities such as local, descendent and indigenous across eight broad themes: (1) promotion and sustainable branding of heritage tourism; (2) empowerment of indigenous communities; (3) authenticity and conservation of heritage; (4) safeguarding of art, culture and cultural landscapes; (5) economic viability for the host communities; (6) interpretation and resolution of dissonant heritage representations; (7) stimulating audience engagement and co-created mindful spaces and; (8) facilitating moral consciousness and stimulating lasting inner transformation in guests and hosts.Scholars can replicate and/or test the proposed guided sustainable marketing model, referred to as the transformative heritage tourism pathway, which is adapted from a) the needs, activities and well-being sequential path of transformation and, b) the socially responsible sustainable marketing doctrine guided by the principles of 'dharma' and 'karma'.This book is unique as it stresses eudaimonia as the ultimate goal of well-being and argues that its pursuit can steer the sustained transformation route toward a higher sense of consciousness and responsible production and consumption of heritage resources. In summary, this book contributes toward advancing the dialogue on sustainable marketing and transformative heritage tourism.It will appeal to researchers, undergraduates and practitioners interested in sustainable marketing, transformative heritage tourism and social, ecological, cultural and economic welfare of visited and visiting destinations.

What is an isotope in chemistry?
Isotopes are atoms of the same element that have the same number of protons but different numbers of neutrons. This results in isotopes having the same atomic number but different atomic masses. Isotopes can have different physical properties, such as stability and radioactivity, due to their varying numbers of neutrons. They are commonly used in various applications, including radiometric dating, nuclear medicine, and tracing chemical reactions.
-
How does an isotope become unstable?
An isotope becomes unstable when the balance between the strong nuclear force and the electromagnetic force within the nucleus is disrupted. This can happen when the nucleus contains too many or too few neutrons compared to the number of protons, leading to an imbalance in the forces holding the nucleus together. As a result, the nucleus may undergo radioactive decay in order to achieve a more stable configuration, releasing energy in the form of radiation.
-
How is the isotope ratio calculated?
The isotope ratio is calculated by comparing the abundance of different isotopes of an element in a sample. This is typically done using mass spectrometry, which separates the isotopes based on their mass-to-charge ratio. The ratio is then calculated by comparing the intensity of the peaks corresponding to the different isotopes. The resulting ratio provides valuable information about the origin and history of the sample, and can be used in various fields such as geology, archaeology, and environmental science.
-
What is the isotope in the periodic table?
Isotopes are variants of a particular chemical element which have the same number of protons but different numbers of neutrons in their nuclei. They are denoted by the element's name followed by a hyphen and the mass number. For example, carbon-12 and carbon-14 are isotopes of carbon. Isotopes can have different physical properties and behaviors due to their differing atomic masses.
